In general, the net premium principle is used for determining insurance premiums. However, in traditional crop insurance sometimes the realized loss is larger than expected loss. To overcome this problem, insurance companies need to determine the premium where there is risk-loading in the premium. There are several methods that can be used to determine this premium. This research focused on the Proportional Hazard Transform method which results a premium called a risk-adjusted premium. In this paper, we give calculations of the risk-adjusted premium with insurance coverage modifications where an ordinary deductible and a policy limit are applied to an insurance contract, that is the risk-adjusted premium for per-loss and per-payment random variable. We provide a relationship between the calculation of the risk-adjusted premium for per-loss and per-payment random variable. The relationship shows that the value of the risk-adjusted premium for a per-payment random variable is greater or equal than the value of the risk-adjusted premium for a per-loss random variable. Simulation with data of losses experienced by rice farmers from insurance companies in Indonesia is presented in this paper. [ABSTRACT FROM AUTHOR]

The coral reefs of Panjang Island, Jepara have been under pressure both by natural factors and by human (anthropogenic) activities, which have resulted in the degradation coral reef area. Research on changes in coral reefs is needed, but the constraints are time, cost, and labor. Remote sensing interpretation of satellite image data is an alternative to determine changes in the area of coral reefs. The use of multitemporal image data can be applied to analyze changes that occur, in this study using four Landsat image data with the acquisition of 2001,2005, 2010, and 2019. The purpose of this study was to determine changes in the area of coral reefs in Panjang Island for the period 2001-2019. The research material used is Landsat 7 and Landsat 8 imagery. The research method is a survey method with a multispectral classification of the maximum possibilities for extracting coral reef cover data from multitemporal images that have been corrected geometrically and radiometrically. A field survey (ground check) was conducted to determine the percentage mapping accuracy. Data on coral reef cover were overlaid to obtain the results of changes in the area of coral reefs for the period 2001-2019. The results showed that the coral reefs in Panjang Island had undergone extensive changes, namely: The area of living coral reefs decreased to 64,34%, with a change rate of 0.17 HaYear-1from 2001-2019. In 2001, the distribution of live coral reefs was seen on the northeast, east, south, and west sides of Panjang Island then reduced coral reefs area, finally left on the northeast and south sides of the island in 2019. Terumbu karang di Pulau Panjang ,Jepara telah mengalami tekanan baik oleh peristiwa alam maupun oleh aktivitas manusia (antropogenik), yang menyebabkan terjadinya degradasi luasan areal. Penelitian tentang perubahan luas terumbu karang sangat diperlukan, namun kendaalanya adalah waktu lama, biaya serta tenaga yang banyak. Penginderaan jauh interpretasi data citra satelit adalah salah satu alternatif guna mengetahui perubahan luas terumbu karang.Pemanfaatan data citra multitemporal dapat diterapkan untuk menganalisis perubahan yang terjadi, dalam penelitian ini menggunakan empat data citra landsat dengan akuisisi tahun 2001,2005, 2010 dan 2019. Tujuan penelitian ini adalah untuk mengetahui perubahan luas terumbu karang di perairan Pulau Panjang perode tahun 2001-2019. Materi Penelitian yang dipergunakan adalah citra Landsat 7 dan Landsat 8.Metode penelitian adalah metode survei dengan klasifikasi multispektral dari kemungkinan maksimum untuk ekstraksi data tutupan terumbu karang dari citra multitemporal yang telah dikoreksi secara geometris dan radiometrik.survei lapangan (ground check) dilakukan untuk mengetahui persentase akurasi pemetaan. Data luas tutupan terumbu karang dioverlay guna mendapatkan hasil perubahaan luas terumbu karang periode tahun 2001-2019. Hasil penelitian menunjukan bahwa Terumbu karang di Pulau Panjang telah mengalami perubahan luas yaitu 64,34% dengan laju penurunan sebesar 0,17 HaTh-1dari Tahun 2001-2019. Pada tahun 2001 sebaran terumbu karang hidup terlihat di sisi timur laut, timur, selatan dan dan barat dari Pulau Panjang, kemudian semakin mengecil areanya, hingga tersisa pada sebelah sisi timur laut dan selatan pulau saja pada tahun 2019.

- Abstract
© 2017 Elsevier B.V. Strontium (Sr) is a valuable metal found in abundance in seawater. However, its recovery from seawater has received little attention despite its many industrial applications. Batch and column adsorption experiments were conducted on the removal of Sr by resorcinol formaldehyde (RF) resin in the presence of co-existing cations at pH 7.5–8.5, where maximum adsorption was found. Batch adsorption capacities of cations followed the decreasing order of Sr > Ca > Mg > K, the order being the same as that of reduction of negative zeta potential. The adsorption data for Sr, Ca and Mg satisfactorily fitted to the Langmuir adsorption model with maximum adsorption capacities of 2.28, 1.25 and 1.15 meq/g, respectively. Selectivity coefficients for Sr with respect to other metals showed that Sr was selectively adsorbed on RF. Column adsorption data for Sr only solution fitted well to the Thomas model. Sr adsorption capacity in the presence of seawater concentrations of Ca, Mg, K and Na was reduced in both batch and column experiments with highest effect from Ca and Mg. However, if Ca and Mg are removed prior to RF adsorption process by precipitation, the negative effect of these ions on Sr removal can be significantly reduced.

Macrobenthos animals are an architect of a variety of roles including as a part of the food web of aquatic ecosystem and improve the structure of the sediment and can determine the quality of the water. Macrobenthos communities have shown their potential role in biomonitoring to analyze contaminant loads due to high sensitivity to organic pollutants along the coastal water area. Besides, it is also used to determine heavy metals and petroleum hydrocarbons in coastal water due to their long sustainability with chemicals are primarily related with industrial calamities and occupational activities. Based on above perspectives, this systematic review has shown interesting findings about the macrobenthic diversity including community composition in the coastal areas of Malaysia. The study has focused on the diversity and abundance of macrobenthos communities along some potential coastal areas of Malaysia which emphasis on the states of Johor, Pulau Pinang, Selangor, Pahang, Terengganu, and Sarawak. Several studies have evidently revealed that pollutants and human activities have contributed to loss of macrobenthos towards abundance (individuals/m2) and species richness. The highest abundance of macrobenthos was Coleoptera sp. (1650 ind./m2 followed by Hemiptera sp. (860 ind./m2) were observed in Sarawak and Crustacea sp. (597 ind/m2) was found in Selangor, respectively. While Crustacea (10 ind/m2) was found as the lowest in the coastal water Pahang only. A major shortcoming among the studies was sampling time along with sampling method which was observed in this systematic review of different studies of macrobenthic assemblages in the coastal waters of Malaysia. However, the existing study reveals the baseline information on macrobenthic community which are still inadequate in Malaysia. Hence, a long-term monitoring for eco-biology and species diversity of macrobenthic assemblages are necessary for their sustainable development in this fascinating tropical coastal water of Malaysia.

- Abstract
© 2016 Elsevier B.V. All rights reserved. Recovering economically valuable rubidium (Rb) from natural resources is challenged due to its low concentration and limited selectivity of extracting agents. Equilibrium and kinetic studies were conducted on the sorptive removal of Rb at low concentration (5 mg/L) using a commercial and a laboratory prepared potassium cobalt hexacyanoferrate (KCoFC). These laboratory and commercial KCoFCs exhibited similar characteristics in terms of chemical composition, surface morphology (scanning electron microscopy) and crystal structure (X-ray diffraction peaks). KCoFC exhibited a higher sorption capacity for Rb (Langmuir maximum sorption 96.2 mg/g) and cesium (Cs) (Langmuir maximum sorption 60.6 mg/g) compared to other metals such as lithium (Li), sodium (Na) and calcium (Ca) (sorption capacity < 2 mg/g). KCoFC sorption capacity for Rb was affected only when Cs was present at twice the concentration of Rb, while the influence of other metals (Li, Na, and Ca) was minimal even at high concentrations. High Rb sorption capacity was due to the exchange of Rb for K inside the crystal lattice and strong sorption on the sorbent surface. These were evident from the data on K release during Rb sorption and reduced negative zeta potential at the sorbent surface in the presence of Rb, respectively. Kinetic sorption of Rb was satisfactorily described by the pseudo-second order model with intraparticle diffusion and exchange of Rb with structural K acting as major rate limiting steps. Up to 74% desorption of Rb was achieved with 0.1 M KCl. Overall, the results established the superior selectivity of KCoFC for Rb sorption.

- Abstract
© 2016 by the authors; licensee MDPI, Basel, Switzerland. Discharging phosphate through wastewaters into waterways poses a danger to the natural environment due to the serious risks of eutrophication and health of aquatic organisms. However, this phosphate, if economically recovered, can partly overcome the anticipated future scarcity of phosphorus (P) resulting from exhaustion of natural phosphate rock reserves. An experiment was conducted to determine the efficiency of removing phosphate from a membrane bioreactor effluent (pH 7.0–7.5, 20, 35 mg phosphate/L) produced in a water reclamation plant by adsorption onto Dowex 21K XLT ion exchange resin and recover the phosphate as fertilisers. The data satisfactorily fitted to Langmuir adsorption isotherm with a maximum adsorption capacity of 38.6 mg_ P/g. The adsorbed phosphate was quantitatively desorbed by leaching the column with 0.1 M NaCl solution. The desorbed phosphate was recovered as struvite when ammonium and magnesium were added at the molar ratio of phosphate, ammonium and magnesium of 1:1:1 at pH 9.5. Phosphate was also recovered from the desorbed solution as hydroxyapatite precipitate by adding calcium hydroxide to the solution at a phosphate to calcium molar ratio of 1:2 at pH 7.0. The P contents of struvite and hydroxyapatite produced were close to those of the respective commercial phosphate fertilisers.

- Abstract
© 2016 Balaban Desalination Publications. All rights reserved. Rubidium (Rb) is a highly valued and economically important metal present in large quantities in many natural and wastewaters. However, its recovery is hampered by its low concentration and extracting agents’ limited selectivity. A batch sorption study showed that a potassium cobalt hexacyanoferrate (KCoFC) sorbent had much higher sorption capacities for Rb and caesium (Cs) than for lithium (Li), sodium (Na) and calcium (Ca). Equilibrium sorption data at pH 7 and 24 ± 1°C for Rb and Cs satisfactorily fitted to the Langmuir model with sorption maxima of 96 and 61 mg/g, respectively. A fixed-bed column (12 cm height) containing a mixture of 2.2 g KCoFC and 19.8 g granular activated carbon had a breakthrough sorption capacity of 61 mg/g when a solution containing 5 mg Rb/L was passed through the column at a velocity of 2.5 m/h (0.7 L/h). When 1 and 5 mg Cs/L were added to the Rb solution, Rb sorption capacity dropped to 46 and 41 mg/g, respectively. During Rb sorption, K from the KCoFC lattice was released. Leaching the column containing sorbed Rb with 0.1 M KCl for 60 min at a velocity of 10 m/h desorbed 99% of sorbed Rb. A process for recovering Rb from sea water reverse osmosis brine is presented.

Coronavirus (SARS-CoV-2) causes a new type of severe acute respiratory syndrome that first appeared in Wuhan in December 2019; it is a very fast-spreading and deadly virus. Therefore, urgent discovery or development of “lead compounds” against this virus is crucial. Natural compounds have always served as a great source, especially the use of traditional medicinal plants, in modern drug discovery. This study aimed to investigate the SARS-CoV-2 protease inhibition potential of the phenolic compounds in the genus Satureja L. The affinities of the chosen natural products were understood using molecular docking simulation against the SARS-CoV-2 protease enzyme. The study proved that three different phenolic compounds namely 5,6-dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7,8-dimethoxy-4H-chromen-4-one, 2-(3,4-dimethoxyphenyl)-5,6-dihydroxy-7,8-dimethoxy-4H-chromen-4-one, and 5,6-dihydroxy-2-(3-hydroxy-4-methoxyphenyl)-7,8-dimethoxy-4H-chromen-4-one obtained from Satureja L. taxa were found as promising against SARS-CoV-2 main protease.

BackgroundMigraine without aura (MwoA) is a very frequent and remarkable comorbidity in patients with idiopathic/genetic epilepsy (I/GE). Frequently in clinical practice, diagnosis of MwoA may be challenging despite the guidance of current diagnostic criteria of the International Classification of Headache Disorders 3 (ICHD-3). In this study, we aimed to disclose the diagnostic gaps in the diagnosis of comorbid MwoA, using a zone concept, in patients with I/GEs with headaches who were diagnosed by an experienced headache expert.MethodsIn this multicenter study including 809 consecutive patients with a diagnosis of I/GE with or without headache, 163 patients who were diagnosed by an experienced headache expert as having a comorbid MwoA were reevaluated. Eligible patients were divided into three subgroups, namely, full diagnosis, zone I, and zone II according to their status of fulfilling the ICHD-3 criteria. A Classification and Regression Tree (CART) analysis was performed to bring out the meaningful predictors when evaluating patients with I/GEs for MwoA comorbidity, using the variables that were significant in the univariate analysis.ResultsLonger headache duration (

University of Technology, Sydney. Faculty of Engineering and Information Technology. The wastewater treatment industry has identified the discharge of inorganic anions such as nitrate, phosphate and fluoride into waterways as a risk to the natural environment and human health. Of the various methods for removing these anions, adsorption/ion exchange methods are promising because they are simple, efficient, economical and result in less sludge production and therefore experience minimal disposal problems. Of the four ion exchange resins tested (Purolite A520E, Purolite A500PS, Purolite FerrIX A33E and Dowex 21k XLT), Purolite A520E emerged as the most efficient adsorbent, having a high adsorption capacity for the removal of nitrate from water. Purolite A520E proved to be the most efficient at removing nitrate (84%) followed by Dowex 21k (81%), and Purolite A500PS (75%) within 120 min. The lowest removal efficiency was found for Purolite FerrIX A33E (48%).The Langmuir adsorption capacity was 33 mg N/g for this resin and the highest column adsorption capacity was 21.3 mg N/g at an inlet concentration of 20 mg N/L, 12 cm bed height and 2.5 m/h filtration velocity. The kinetics of nitrate adsorption by Purolite A520E in the batch study was satisfactorily described using pseudo-first-order, pseudo-second-order and HSDM models. The experimental and Thomas models predicted breakthrough adsorption capacities (12.0-13.5 mg N/g and 8.2-9.7 mg N/g, respectively) agreed fairly well. The presence of other co-ions such as SO₄²⁻, F⁻, C1⁻ and PO₄³⁻ did not compete much with nitrate at equal concentrations for adsorption on Purolite A520E; only high concentrations reduced the effectiveness of this resin’s ability to adsorb nitrate. Moreover, at all nitrate to phosphate ratios in solution, the ratio of nitrate to phosphate adsorbed was higher for Purolite A520E which suggested that the nitrate selectivity for adsorption was higher than phosphate. It was found that solution pH had little effect on nitrate adsorption in the pH range 5-8. Moreover, Purolite A520E was regenerated and used at least three times without significantly reducing the adsorption capacity. Of the six adsorbents tested in a batch study (Purolite A520E, Purolite A500PS, Purolite FerrIX A33E, Dowex 21k XLT, HFO (iron (iii) oxide HFeO₂) and Zirconium (IV) hydroxide (H₄O₄Zr)), Purolite FerrIX A33E had the highest phosphate removal efficiency (98%) followed by Dowex 21k (91%), Zirconium (IV) hydroxide (89%), Purolite A500PS (75%) and Purolite A520E (69%) within 240 min. HFO was found to have the least removal efficiency (36%). The batch adsorption isotherm data for Purolite FerrIX A33E was satisfactorily explained using the Langmuir, Freundlich and Tempkin isotherm models. Meanwhile the kinetic adsorption data fitted reasonably well to the pseudo-second-order, Elovich and intraparticle diffusion models. The Langmuir maximum adsorption capacity of Purolite FerrIX A33E was 48 mg P/g which constituted one of the highest phosphorus adsorption capacities reported in the literature. Three empirical models - Bohart-Adams, Thomas and Yoon-Nelson - and a numerical model based on the advection-dispersion equation satisfactorily described phosphate adsorption behaviour in a fixed-bed column containing Purolite FerrIX A33E. The phosphate adsorption capacity of the column was estimated by: firstly, the Thomas model to be 22.7 mg P/g; and secondly, the breakthrough curve calculation to be 16.3 mg/g at the inlet concentration of 30 mg P/L, 12 cm bed height and 10 m/h filtration velocity. pH had little effect on phosphate adsorption by Purolite FerrIX in the pH range 4 – 10. The decreasing order of the anions’ competition with phosphate was as follows: SO₄²⁻ > C1⁻ > NO₃⁻ > F⁻. The Purolite FerrIX A33E resin was regenerated by leaching the adsorbed phosphate with 1 M NaOH solution and reused at least four times without significantly reducing the adsorption capacity. This phosphorus desorbed was recovered as struvite by adding magnesium chloride (MgC1₂.6H₂O) and ammonium sulphate (NH₄)₂SO₄ at the molar ratio of phosphate, ammonium and magnesium of 1:1:1. Calcium hydroxide (Ca (OH) ₂) was added to the desorbed solution to recover phosphorus as hydroxyapatite at the molar ratio of phosphate and calcium of 1:0.5 and 1:2. The XRD and FTIR analyses confirmed the recovered compounds were struvite and hydroxyapatite. These compounds’ phosphorous content was 12-14% which was similar to the phosphorus content of struvite and hydroxyapatite. Hydrous ferric oxide (HFO) had the highest fluoride adsorption capacity of seven adsorbents tested (Purolite A520E, Purolite A500PS, Purolite FerrIX A33E, Dowex 21k, HFO (iron (iii) oxide HFeO₂), Zirconium (IV) hydroxide (H₄O₄Zr) and α-Alumina (A1₂O₃)). Among the seven adsorbents, HFO had the highest fluoride removal efficiency (56%) followed by Dowex 21k (52%), Zirconium (IV) hydroxide (38%), Purolite A502PS (35%), Purolite FerrIX A33E (29%) and Purolite A520E (25%) within 120 min. The lowest removal efficiency was found for α-Alumina (4%). The batch adsorption of fluoride on HFO was satisfactorily explained using both the Langmuir and Freundlich isotherms while the column adsorption data fitted reasonably well to the Thomas model. However, by using an artificial neural network approach the model’s capability did improve. The Langmuir maximum adsorption capacity at pH 6.5 was 6.71 mg F/g and the highest column breakthrough adsorption capacity was 7.06 mg F/g at the inlet concentration of 30 mg F/L, 12 cm bed height, pH 5 and 2.5 m/h filtration velocity. The adsorption capacity predicted by the Thomas model was also highest (12.7 mg F/g) for these experimental conditions. The kinetic data concerning the fluoride adsorption on HFO was better described with the pseudo-second-order model compared to the pseudo-first-order model. The HFO was regenerated by leaching the adsorbed fluoride with 0.1 M NaOH solution and reused for at least three times. However, the fluoride adsorption capacity declined with repeated use.

Objective: Neurological manifestations associated with coronavirus disease-2019 (COVID-19) are broad and heterogeneous. Although the predominant clinical presentation is respiratory dysfunction, concerns have been raised about the neurological hallmarks. Many reports suggest some findings on electroencephalography (EEG) can be relevant to COVID-19. Materials and Methods: Patients with COVID-19 admitted to hospital and referred for EEG from March 1, 2020 to February 15, 2021, were retrospectively enrolled. When research databases were queried with the terms “COVID-19 (ICD code: 10: U07.3) and “EEG”, total number of patients obtained was 32. Number of patients excluded due to unconfirmed diagnose with COVID-19 was 12. Twenty adult patients with certain diagnose of COVID-19 who underwent 21-electrode routine EEG during the outbreak with neurological deterioration were identified. Results: Background abnormalities was evident in one of fourth patients (n=5, 25%). Mild diffuse slowing (n=3, 15%) and focal slowing (n=3, 15%) with left frontotemporal tendency (n=2, 10%) were observed. Epileptiform abnormalities and seizures were detected showing focal (n=4, 20%) or generalized onset (n=1, 5%). Conclusion: Here we performed a retrospective single-centre study to evaluate the electroencephalographic findings in patients diagnosed with COVID-19 since it remains unknown. it needs to be more clarified with increasing number of recordings

Epilepsia partialis continua is characterized by continuous clonic contractions of a certain area of the body. One of the most common causes of Epilepsia partialis continua in adults is cerebrovascular events. Other causes include meningoencephalitis, Rasmussen encephalitis, diabetic nonketotic hyperosmolar coma, central nervous system malignancies, tuberculosis, cerebral venous thrombosis, or idiopathic. A 70-year-old male patient was admitted to the emergency department with abdominal muscle contractions for about an hour. Neurodiagnostic imaging revealed an encephalomalasia area secondary to the area of the previous infarction in the left frontoparietal region. Focal motor findings were controlled within 5 min after the VPA (valproic acid) treatment at a dose of 15 mg/kg admission, and then the treatment was continued with 1500 mg/day Valproic acid. Here, we aimed to emphasize that myoclonic jerks confined to the abdominal region is a rare motor phenomenon and may be a feature of Epilepsia partialis continua, the history of stroke should be questioned in the etiology, and seizures can be controlled with IV Valproic acid treatment.

- Abstract
© 2014, Islamic Azad University (IAU). Removing excessive nitrate from water is essential because it causes eutrophication which in turn has a harmful effect on aquatic life, resulting in a reduction in biodiversity and posing a danger to people’s health when the water is used for drinking. In this study, nitrate removal from aqueous solutions was studied using an ion exchange resin (Purolite A520E) in batch and fixed-bed column experiments. Batch adsorption kinetics was very well described by pseudo-first-order, pseudo-second-order and homogeneous surface diffusion models for resin doses 1.5 and 3.0 g/L at a nitrate concentration 20 mg N/L. Column kinetic data satisfactorily fitted to the empirical Thomas model and a numerical model based on advection–dispersion equation for filtration velocities 2.5 and 5.0 m/h at a column height of 12 cm and inlet concentration 20 mg N/L. The experimental and Thomas model predicted breakthrough adsorption capacity ranges for the two filtration rates were 12.0–13.5 and 8.2–9.7 mg N/g, respectively, whereas the maximum adsorption capacity determined using Langmuir adsorption isotherm model in the batch study was 32.2 mg N/g.

Coral reefs currently are suffered from natural factors along with increasing anthropogenic activity. Panjang Island, a small reef island located in Jepara Regency, may also be experiencing such conditions. Therefore, this work was aimed to observe the condition of the coral cover of Panjang Island. Line intercept transect was applied to survey the coral cover and mortality index from fourteen stations. Insitu data consisted of the bottom substrate composition of the reefs and the physical parameters of the sea. The secondary data, i.e. coral reef area maps from 2001 to 2019 were taken from Landsat Image 7 and 8, data of wind were obtained from www.ogimet.com, while tidal data were collected from BMKG. The bathymetry was determined from the Geospatial Information Agency data, salinity global analysis forecast Phy 001.024 (CMEMS). Sea surface temperature (SST), and chlorophyll-a distribution were analyzed using ENVI software. The result showed that Panjang Island has a poor to the moderate condition of hard coral. Two out of six categories of abiotic and dead coral were found to be high. The mortality index of coral was in the high category (average 0.52). During research periods the sea waters were characterized by high sea surface temperature (29.34-30.94°C), chlorophyll-a was also tended to be high (0-2.65 mg.m-3), and an average of salinity was high 32 ‰. The weak currents came to all sides of the island, therefore the coral reef was not exposed to extreme currents. The waves came from the east, then the energy decreases after being blocked by coral reefs on the eastern side of the island, so that coral reefs in the northeast and south sides were safer to be exposed. The results suggest that hydrodynamic ecology directly or indirectly affected the percentage of coral cover and mortality index at the reefs of Panjang Island.

- Abstract
Phosphorus removal is important as it causes eutrophication that in turn has a harmful effect on fish and other aquatic life, resulting in a reduction in biodiversity as well as unfavourable human environmental health. In this study, phosphorus removal from aqueous solutions was studied using an ion-exchange resin (Purolite FerrIX A33E) in fixed-bed column experiments. The effects of adsorbent bed height (3-19 cm) on the breakthrough characteristics of the adsorption system were studied. An increase in bed height (3-19 cm) increased adsorption capacity but the breakthrough time was shorter. As the bed height increased, the detention time increased and the phosphate was in contact with the purolite ion-exchange resin for a longer time, resulting in more efficient removal of phosphate. The shape of breakthrough curve was steeper for a shorter bed height. A mathematical model (advection-dispersion equation) was solved numerically to predict the dynamic behaviour of the columns. Finally, sensitivity analysis results apparently revealed that the dynamic adsorption behaviours of phosphate in Purolite FerrIX A33E were mainly controlled by the external mass transfer rather than the axial dispersion and the intra-particle diffusion. © 2013 © 2013 Balaban Desalination Publications.

- Abstract
Elevated intake of fluoride (F), mainly through drinking water, is a major threat to human health worldwide. A study was conducted to remove F from aqueous solution by adsorption onto hydrous ferric oxide (HFO) in batch and fixed-bed column experiments. Of the seven adsorbents (four anion exchange resins, three multivalent metal oxides) tested, HFO had the highest adsorption capacity. Fluoride adsorption on HFO fitted well to Langmuir and Freundlich models with a Langmuir adsorption maximum of 6.71mg F/g at pH 6.5. Fluoride adsorption continuously decreased from pH 3 to 7. Point of zero charge of HFO was pH 5 which fell to pH 4 in the presence of 10mg F/L and 1g HFO/L, indicating that F was specifically adsorbed on HFO. Fluoride was not desorbed by 0.1M NaCl and 0.1M Na2SO4 but effectively desorbed by 0.1M NaOH. The F adsorption capacity in column experiments (10% or 20% HFO+90% or 80% anthracite) was progressively reduced with increasing number of adsorption/NaOH desorption cycles up to three cycles reaching a final value of 3.26mg F/g HFO. The breakthrough data from column studies at different bed heights, inlet concentrations, and pHs were fairly well described by Thomas model, but using an artificial neural network approach improved the model capability. © 2014 Elsevier B.V.

- Abstract
Removing phosphate from water is important as it causes eutrophication, which in turn has a harmful effect on aquatic life, resulting in a reduction in biodiversity. On the other hand, recovery of phosphate from phosphorus containing wastewater is essential for developing an alternative source of phosphorus to overcome the global challenge of phosphorus scarcity. Phosphate removal from aqueous solutions was studied using an iron oxide impregnated strong base anion exchange resin, Purolite FerrIX A33E in batch and fixed-bed column experiments. Phosphate adsorption in the batch study satisfactorily fitted to the Langmuir isotherm with a maximum adsorption capacity of 48mgP/g. In the column study, increase in inlet phosphate concentration (5-30 mgP/L), and filtration velocity (2.5-10 m/h) resulted in faster breakthrough times and increase in breakthrough adsorption capacities. Increase in bed height (3-19 cm) also increased adsorption capacity but the breakthrough time was slower. The breakthrough data were reasonably well described using the empirical models of Bohart-Adams, Thomas, and Yoon-Nelson, except for high bed heights. Phosphate adsorbed was effectively desorbed using 1M NaOH and the adsorbent was regenerated after each of three adsorption/desorption cycles by maintaining the adsorption capacity at >90% of the original value. Greater than 99.5% of the desorbed P was recovered by precipitation using CaCl2. © 2013 The Korean Society of Industrial and Engineering Chemistry.

Ancient physicians frequently used the resin of Ferula species to treat cancer. Today, some folkloric recipes used for cancer treatment also contain the resin of Ferula species. The dichloromethane extract of the roots of Ferula huber-morathii exhibited cytotoxic activities against COLO 205 (colon), K-562 (lymphoblast), and MCF-7 (breast) cancer cell lines (IC50 = 52 µg/mL, 72 µg/mL, and 20 µg/mL, respectively). Fifteen sesquiterpene coumarin ethers with cytotoxic activity were isolated from the dichloromethane extract of the roots of F. huber-morathii using bioactivity-directed isolation studies. Extensive spectroscopic analyses and chemical transformations have elucidated the structures of these sesquiterpene coumarin ethers as conferone (1), conferol (2), feselol (3), badrakemone (4), mogoltadone (5), farnesiferol A (6), farnesiferol A acetate (7), gummosin (8), ferukrin (9), ferukrin acetate (10), deacetylkellerin (11), kellerin (12), samarcandone (13), samarcandin (14), and samarcandin acetate (15). The absolute configuration of samarcandin (14) was unequivocally determined by the X-ray crystallographic analysis of the semi-synthetic (R)-MTPA ester of samarcandin (24). Conferol (2) and mogoltadone (5) were found to be the most potent cytotoxic compounds against all three cancer cell lines; furthermore, these compounds exhibit low cytotoxic activity against the non-cancerous human umbilical vein epithelial cells (HUVEC) cell line. Investigation of the biological activity mechanisms of mogoltadone (5) revealed that while suppressing the levels of Bcl-XL and procaspase-3 in the COLO 205 cancer cell line, it did not have a significant effect on the Bcl-XL, caspase-3, and β-catenin protein levels of the HUVEC cell line, which may explain the cytotoxic selectivity of mogoltadone (5) on cancer cell lines.

Summary Gelastic seizures are typically associated with hypothalamic hamartoma. Given the rarity of gelastic seizures, pathways for the motor and emotional aspects of laughter have been hypothesized but remain unclear. Only few case reports of patients with tuberous sclerosis complex who developed gelastic epilepsy have been reported. In this case study, we report a case of TS that presented itself mainly with dermatologic manifestations and without any neurological findings other than gelastic seizures. Ictal EEG revealed an active epileptic activity on the right fronto-temporal region. Clinical and laboratory findings were consistent with gelastic epilepsy that originated from temporal and extra-temporal lobes. Seizures were controlled using carbamazepine and levetiracetam polytherapy. In our case, there is no evidence of cortical and subcortical tubers, subependymal glial nodules, giant cell astrocytomas or aneurysm.

Abstract The international CIHLMU Occupational Safety and Health Symposium 2019 was held on 16th March, 2019 at the Ludwig-Maximilians-Universität Munich, Germany. About 60 participants from around the world representing occupational health and safety professionals, students, instructors from several institutions in Germany and abroad, attended the symposium. The main objective of the symposium was to create awareness on global challenges and opportunities in work-related respiratory diseases. One keynote lecture and six presentations were made. While the keynote lecture addressed issues on occupational diseases in the twenty-first century, the six presentations were centered on: Prevention and control of work-related respiratory diseases, considerations; Occupational health and safety in Mining: Respiratory diseases; The prevention of TB among health workers is our collective responsibility; Compensation and prevention of occupational diseases and discussion on how artificial intelligence can support them: Overview of international approaches; Work-related Asthma: Evidence from high-income countries; and The role of imaging in the diagnosis of work- related respiratory diseases. A panel discussion was conducted following the presentations on the importance and challenges of data acquisition which is needed to have a realistic picture of the occupational safety and health status of workers at different levels. The current summary is an attempt to share the proceedings of the symposium.

INTRODUCTION: This study is aimed to determine the effect of ventrogluteal injection training on the health professionals' knowledge levels and preferences about the use of the ventroglu- teal region for intramuscular injections. METHODS: The semi-experimental study was conducted as a pretest and post-test design. This study was performed at a private hospital between January and September 2018 with 81 health professionals. The data were collected with a questionnaire in line with the lit- erature. Participants were divided into two groups, after completion of questionnaire forms. Each group received 2 hours of in-service, and one-to-one theoretical and also practical training on models. After the training each participants' level of proficiency on their ventrogluteal injections was evaluated with a form developed by the researchers. Six months later using the same questionnaire form their knowledge level and preferences on the use of ventrogluteal region for intramuscular injections were evaluated. RESULTS: After the training, it was seen that the average number of correct answers about the information for the ventrogluteal region was increased. It was determined that 60.5% of the participants did not prefer to use the ventrogluteal region for injections before the training, but this number was lowered to 29.6% after the training. In addition to this, the 27.5% who used the dorsogluteal region for injections before the training indicated that they would prefer the ventrogluteal region after the training. DISCUSSION AND CONCLUSION: It was determined that less than expected number of professionals chose the ventrogluteal region as the first preference for IM injection despite the fact that the par- ticipants gained the proficiency for IM injection on ventrogluteal region after the training. As a result, it is recommended that in-service training should be given to health profes- sionals and they should be encouraged to use the ventrogluteal region for intramuscular injections during clinical practices.

congenital alveolar rhabdomyosarcoma ,childhood ,pleural effusion ,Medicine - Abstract
Rhabdomyosarcoma (RMS) is a malignant form of neoplasm that originates from skeletal muscle. RMSs can exist anywhere in the human body but are more commonly detected in the neck region and extremities. The alveolar type is one of the subtypes of RMS that has a poor prognosis. Because the clinical manifestation of a tumour can be a painless mass, symptoms might be non-contributary to the diagnosis. Herein, a four-month-old girl was admitted to the emergency department with complaints of respiratory distress without a runny nose, cough, and fever. Recurrent effusions subsided with subsequent tube thoracostomy. Video-assisted thoracoscopic surgery (VATS) was performed to determine the aetiology of the recurrent effusion. The Tru-Cut biopsy obtained during VATS resulted in the diagnosis of alveolar rhabdomyosarcoma. Pleural effusion decreased, and the tube drainage was stopped rapidly after first vincristine, actinomycin-D, and cyclophosphamide chemotherapy cycle. Persistent and recurrent pleural effusions should alert physicians to rule out unusual diagnoses like that of our case.

Medicine ,Science - Abstract
There is an increasing number of cancer patients undertaking treatment-focused genetic testing despite not having a strong family history or high a priori risk of being carriers because of the decreasing cost of genetic testing and development of new therapies. There are limited studies on the psychosocial outcome of a positive result among breast cancer patients who are at low a priori risk, particularly in women of Asian descent. Breast cancer patients enrolled under the Malaysian Breast Cancer Genetic Study between October 2002 and February 2018 were tested for BRCA1, BRCA2 and PALB2 genes. All 104 carriers identified were invited by a research genetic counsellor for result disclosure. Of the 104 carriers, 64% (N = 66) had low a priori risk as determined by PENN II scores. Psychosocial, risk perception and health behaviour measures survey were conducted at baseline (pre-result disclosure), and at two to six weeks after result disclosure. At baseline, younger carriers with high a priori risk had higher Cancer Worry Scale scores than those with low a priori risk but all scores were within acceptable range. Around 75% and 55% of high a priori risk carriers as well as 80% and 67% of low a priori risk carriers had problems in the “living with cancer” and “children” psychosocial domains respectively. All carriers regardless of their a priori risk demonstrated an improved risk perception that also positively influenced their intent to undergo risk management procedures. This study has shown that with sufficient counselling and support, low a priori risk carriers are able to cope psychologically, have improved perceived risk and increased intent for positive health behaviour despite having less anticipation from a family history prior to knowing their germline carrier status.

Owing to their facile integration into existing commercial products, high volume manufacturing of organic solar cells (OSCs) can be expected in the upcoming years. Therefore, it is important to evaluate the performance and sustainability of various active layer coating methods for OSCs. Herein, we compare four active layer coating processes: spin-coating, blade-coating, spray-coating and push-coating for poly(2,7-carbazole-alt-dithienylbenzothiadiazole):[6,6]-Phenyl-C71-butyric acid methyl ester (PCDTBT:PC71BM) active layers deposition. The optical, morphological and photovoltaic parameters of the active layers are studied. The suitability of each coating method for industrial manufacturing of PCDTBT:PC71BM OSCs is discussed in terms of environmental impact, necessary investments and running costs. Our results confirm that, despite producing high quality and high performance OSCs, spin-coating is unsuitable for high volume manufacturing due to the large amounts of materials and hazardous solvents wasted in the process. Blade-coating provides a good balance between low running costs, low environmental impact and decent performances but the process introduces lateral compositional gradients which could be detrimental for large area OSC processing. Spray-coating requires minimal initial investments but has relatively low performance and low manufacturing sustainability. Push-coating yields OSCs which perform as well as spin-coated ones, with a much lower environmental impact and cost. We should thus look forward to seeing whether this green and sustainable technology can develop into a large area coating process in the future.

The COVID-19 pandemic has impacted the investment climate in the Indonesian capital market, influencing investors’ decisions in choosing resilient stocks during the crisis. Socially responsible stocks are perceived to be more reliable during a crisis than other stocks. This study aims to assess the difference in abnormal returns before and after the five events related to COVID-19 news, using the Banks Sub-Sector representing the finance sector and SRI-KEHATI Index stocks. A purposive sampling technique was used to select samples of 41 stocks of the Banks Sub-Sector and 11 stocks of the SRI-KEHATI index. Data analysis employed various statistical tests, including paired-sample Wilcoxon signed-rank test and paired- sample t-test. The findings of this study indicate various significant abnormal returns and trading volumes for the two classifications.

Environmental sciences ,GE1-350 - Abstract
Sustainability issues have increased the need for stakeholders toward environmental information disclosure. Environmental information is pivotal for stakeholders to assess a firm’s environmental performance. A firm’s environmental performance significantly influences a firm’s environmental properly. This study examines the influence of a firm’s environmental performance on Firm environmental disclosure, moderated by the firm’s characteristics. The study involved fifty listed firms on Indonesia Stock Exchange (IDX) and PROPER participants (Company Performance Rating Program in Environmental Management) from 2017 to 2020. The firm’s characteristics in this study refer to size, profitability, and leverage. The estimated Generalized least square panel regression test indicated that firm environmental performance significantly explains the variance of environmental disclosure. The influence of firm environmental performance on firm environmental disclosure is significantly moderated by profitability and firm size.

- Abstract
Water pollution due to the excessive presence of nutrients (nitrogen and phosphorus) is a serious environmental worldwide problem, because both species are implicated in the eutrophication of receiving surface waters and elevated nitrate concentration in drinking water can be toxic to infants. The removal efficiencies of nitrate and phosphate from water spiked with different ratios and concentrations of these nutrients by two ion-exchange resins (Purolite A500PS and Purolite A520E) were studied in batch kinetics and equilibrium adsorption experiments. Both purolites were found to be selective towards nitrate removal at all ratios of nitrate to phosphate in solution. Purolite A520E showed higher (<85%) removal efficiency of nitrate than Purolite A500PS (about 65%) from a solution containing 20mgN/L as nitrate and 10mgP/L as phosphate at a resin dose of 1.5 g/L. However, Purolite A500PS showed higher (65%) removal of phosphate than Purolite A520E (48%). Langmuir and Freundlich isotherm models fitted well for the adsorption of nitrate on Purolite A520E (R2 = 0.95-0.96). However, the adsorption of nitrate on Purolite A500PS can be explained satisfactorily only by Freundlich model (R2 = 0.98). The adsorption of phosphate on the resins fitted well to Freundlich model (R2 = 0.90) for Purolite A500PS as well as for Purolite A520E (R2 = 0.90). The adsorption of phosphate and nitrate on both ion-exchange resins was much better described by pseudo-second-order kinetic model (R2≥0.99) than by pseudo-first-order kinetic model (R2 = 0.25-0.94).© 2012 Desalination Publications.

Serous cystadenoma is a rare benign cystic lesion of pancreas. They are mostly known as benign cystic tumors of pancreas but malign transformation as serous cystadenocarcinoma is also reported. It is more commonly observed in women with the mean age of onset is 62 years. The majority of patients present nonspecific symptoms such as abdominal pain, weight loss, nausea, vomiting, fever, and melena. One-third of the patients are asymptomatic. A 60-year-old woman presents with abdominal pain and nausea for 1 month was admitted. Physical and laboratory findings were normal. Abdomen computed tomography scan confirmed a large number of millimetric cysts of 45 × 47 × 50 mm in size at the head of the pancreas. Due to patient's symptoms and mass effect, Whipple procedure was performed. In the gross examination, a nodular area of 5 × 5 × 4 cm was observed in the head of the pancreas. The microscopic examination of the material revealed cystic structures with fibrous stroma dotted with single layered cuboidal epithelium in the pancreatic tissue. The pathology report confirmed benign macrocystic serous cystadenoma. Serous cystadenomas are rare benign cystic lesions of the pancreas. Although they are benign lesions, it is crucial to differentiate them from other cystic lesions of the pancreas and malignant serous cystadenocarcinomas.

In 2013, the German Federal Foreign Office launched the German Biosecurity Programme with the aim to minimise risks associated with biological substances and pathogens. In this context, the German-Kazakh Network for Biosafety and Biosecurity was established in 2013 and constitutes a successful collaboration between Kazakh and German biomedical organisations, under the co-management of the Bundeswehr Institute of Microbiology (IMB), and the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH. Ever since then, a network of scientists, stake holders and policymakers has been established, aiming to work on highly pathogenic, potential biological warfare agents with the focus on biosafety and biosecurity, surveillance, detection and diagnostics, networking and awareness raising of these agents in Kazakhstan. Over the past 8 years, the project members trained four PhD candidates, organised over 30 workshops and trainings with more than 250 participants and conducted more than 5,000 PCR assays and 5,000 serological analyses for surveillance. A great success was the description of new endemic areas for Orthohantaviruses, the mixture of two Crimean-Congo haemorrhagic fever virus genetic clusters, new foci and genetic information on tick-borne encephalitis virus and rickettsiae in Kazakh oblasts. The latter even led to the description of two new genogroups. Furthermore, joint contributions to international conferences were made. In this report, we summarise the evolution of the German-Kazakh Network for Biosafety and Biosecurity and critically reflect on the strengths and possible weaknesses. We were able to establish a viable network of biosafety and biosecurity shareholders and to accomplish the aims of the German Biosecurity Programme to lower biosecurity risks by increased awareness, improved detection and diagnostic methods and surveillance. Further, we reflect on forthcoming aspects to lead this interstate endeavour into a sustainable future.
