Group 14 Zintl anions [Ex]q−(E = Si–Pb,x= 4, 5, 9, 10) are synthetically accessible, and their diverse chemical reactivity makes them valuable synthons in the construction of larger nanoclusters with remarkable structures, intriguing patterns of chemical bonding, and tunable physical and chemical properties. A plethora of novel cluster anions have now been isolated from the reactions of polyanionic [Ex]q−precursors with low-valent d-/f-block metal complexes, main-group organometallics, or organics in polar aprotic solvents. The range of products includes intermetalloid clusters with transition metal atom(s) embedded in main-group element cages, organometallic Zintl anions in which [Ex]q−acts as a ligand, intermetallic Zintl anions where [Ex]q−is bridged by ligand-free transition metal atom(s), organo-Zintl anions where [Ex]q−is functionalized with organic-group(s), and oligomers formed through oxidative coupling reactions. The synthesis and characterization of these unconventional complexes, where important contributions to stability come from ionic, covalent, and metal–metal bonds as well as weaker aurophilic and van der Waals interactions, extend the boundaries of coordination chemistry and solid-state chemistry. Substantial progress has been made in this field over the past two decades, but there are still many mysteries to unravel related to the cluster growth mechanism and the controllable synthesis of targeted clusters, along with the remarkable and diverse patterns of chemical bonding that present a substantial challenge to theory. In this Account, we hope to shed some light on the relationship between structure, electronic properties, and cluster growth by highlighting selected examples from our recent work on homoatomic deltahedral [Ex]q−anions, including (1) germanium-based Zintl clusters, such as the supertetrahedral intermetallic clusters [M6Ge16]4–(M = Zn, Cd) and the sandwich cluster {(Ge9)2[η6-Ge(PdPPh3)3]}4–with a heterometallicGe@Pd3interlayer; (2) tin-based intermetalloid clusters [Mx@Sny]q−and the application of [Co@Sn9]4–in bottom-up synthesis; and (3) lead clusters with precious metal cores, including the largest Zintl anion [Au12Pb44]8–. In addition to their intrinsic appeal from a structural and electronic perspective, these new cluster anions also show promise as precursors for the development of new materials with applications in heterogeneous catalysis, where we have recently reported the selective reduction of CO2.

Introduction: Globally, there is a dramatic rise in cesarean section rate which has increased the maternal morbidity and adverse effects in a subsequent pregnancy. Robson’s classification will aid in the optimization of the cesarean section use, assessment of the strategies aimed to decrease the cesarean section rate and thus improve the clinical practices and quality of care in various health care facilities. The main aim of this study is to find out the prevalence of caesarean section for Robson’s group 2 among total caesarean sections done in a tertiary care hospital. Methods: A descriptive cross-sectional study was carried out at a tertiary care centre in Nepal from August 2020 to January 2021. Ethical approval was taken from the institutional review committee (reference number: 1607202003) and data were entered using Robson’s criteria. The convenient sampling technique was used. Data was analyzed using Microsoft Excel. Point estimate at 95% Confidence Interval was calculated along with frequency and percentage for binary data. Results: According to Robson’s group 10 classification, among 380 caesarean sections, 110 (28.94%) (24.38-33.50 at 95% Confidence Interval) cases were in Robson’s group number 2. Conclusions: This study showed that the prevalence of caesarean section which lies in Robson’s group 2 in our study is higher than the standard of World Health Organization. It showed that Robson’s group 2 was one of the significant contributors to the greater caesarean section rate. Improved case selection, standardization, and protocol for induction of labour as well as regular audit could also reduce caesarean section rates.

In this article, we present a selection of previously unpublished metal jewellery (decorative pins, fibulae, bracelets, neck rings, and earrings) housed at Diyarbakır Museum, where they were acquired by requisition or purchase. The objective of this study is to evaluate these jewellery items with common characteristics as a group and to provide a chronological assessment based on comparative typological analysis in reference to ancient Near Eastern jewellery. This contribution furthers our knowledge about the archaeological record of the Upper Tigris basin in southeast Turkey, where Diyarbakır province is located. All categories of jewellery items examined in this study show typological variability in sub-types and exhibit stylistic diversity. The majority are made of bronze, while fewer are gold-plated or made of gold, silver or iron. Jewellery items vary in terms of manufacturing technology, as well: toggle pins are produced by lost wax (cire pérdue) technique; fibulae and bracelets are made by casting; and earrings and metal neck rings are made by hammering. Decorations are executed as incised patterns in linear style. Figurative adornments of toggle pins, fibulae, bracelets, and neck rings bear testimony to the high level of craftsmanship that their makers had achieved. These artefacts from Diyarbakır Museum, like most known jewellery in the archaeological record, must have been used as grave offerings or worn as items of personal adornment, amulets or accessories for garments. Based on comparative analysis, the 47 jewellery items in Diyarbakır Museum examined here are dated to the Early and Middle Iron Age.

Objective: To determine the prescription patterns of antiarrhythmic drugs and variables associated with their use in a population of patients affiliated with the Colombian Health System. Methods: A cross-sectional study was performed on a population database with patients who received antiarrhythmics from March to May 2016. Sociodemographic, pharmacological and comedication variables were included. SPSS-24 was used for data analysis using X2 tests and multivariate analyses. Results: In total, 2772 patients were treated with antiarrhythmics in the evaluated period. The mean age was 70.1 ± 13.1 years, and 51.2% were women. In total, 79.4% used a β-blocker, 58.5% amiodarone and 2.9% a calcium channel blocker. Moreover, 1192 (43.0%) patients were prescribed a single antiarrhythmic, and 1580 (57.0%) received two or more. There were 2603 patients (93.9%) with comedication, including lipid-lowering drugs (62.6%), inhibitors of the renin angiotensin aldosterone system (62.6%) and antiplatelet drugs (42.0%). Age older than 65 years increased the probability of comedication (odds ratio [OR]: 2.48; 95% confidence interval [95% CI]: 1.59-3.85), and the risk was proportional to age. We identified 1364 patients treated with conditional risk medications for QT prolongation (49.2%), 68 with a possible risk (2.5%) and 171 (6.2%) with a known risk. Conclusion: Antiarrhythmic drugs recommended by clinical practice guidelines are mainly used; however, risk interactions interactions of QT prolongation were identified and should be taken into account by physicians to avoid adverse events or complications. Resumen Objetivo: determinar los patrones de prescripción de fármacos antiarrítmicos y variables asociadas a su utilización en una población de pacientes afiliados al sistema de salud de Colombia. Métodos: estudio de corte transversal sobre una base de datos poblacional con pacientes que recibieron antiarrítmicos entre marzo y mayo de 2016. Se incluyeron variables sociodemográficas, farmacológicas y de comedicación. Para el análisis de datos se utilizó SPSS-24, realizando pruebas X2 y análisis multivariado. Resultados: se encontraron 2 772 pacientes en tratamiento con antiarrítmicos en el periodo evaluado, la edad promedio fue 70,1 ± 13,1 años, 51,2 % eran mujeres. El 79,4% utilizó algún β-bloqueador, 58,5% amiodarona y 2,9 % algún bloqueante de canales de calcio. Al 43 % se les prescribió un solo antiarrítmico y 57 % recibieron dos o más. El 93,9 % tenía con alguna comedicación, especialmente hipolipemiantes (62,6 %), inhibidores del sistema renina angiotensina aldosterona (62,6 %) y antiagregantes (42 %). Ser mayor de 65 años aumentó la probabilidad de comedicación (OR:2,48; IC95 %:1,59-3,85) y el riesgo fue proporcional al incremento de la edad. El 49,2 % (n=1364) estaban tratados con medicamentos de riesgo condicional de prolongación del QT, 2,5 % (n=68) con riesgo posible y 6,2% (n=171) de riesgo conocido. Conclusión: se están utilizando los mismos fármacos recomendados por las guías de práctica clínica; sin embargo, se encontraron interacciones de riesgo de prolongación del intervalo QT que deben ser tenidas en cuenta para evitar eventos o complicaciones en los pacientes.

The penetration and use of smart mobile phones with internet connectivity paved way to the increased use of social media tools and among them, WhatsApp is widely used by farmers for personal and group use. The efforts made by public institutions, development departments in reaching farmers and general public through WhatsApp has led to a creation of number of farmers WhatsApp groups for sharing of agricultural knowledge and information. The present study was carried out to analyse the content shared through KVK WhatsApp group. Viluppuram KVK WhatsApp group was purposively selected and the content shared was analyzed by non-participant observation method for 30 days. Data analyzed using frequency and percentage analysis. It was found that majority (83.97%) of the content shared by the farmers were related to agricultural activities. Farmers preferred to use text communication (37.18%) over other mode of messages. Farmers were actively engaged during morning hours in WhatsApp group due to their free time rather than later hours. Farmers opined that WhatsApp positively impacted them in obtaining timely information as well as personalized information.

The food system of the Brazilian Armed Forces is governed by specific rules and financed by federal collections. In this context, the research proposes a methodology that allows evaluating the average level of satisfaction of users of the foodservice provided in the Procurement of the 2nd Engineering Group, located in the city of Manaus, capital of Amazonas. Therefore, an online questionnaire was developed and applied, adapted from the model proposed by Barros (2013), using four quality dimensions: (i) product quality; (ii) environmental conditions; (iii) facilities; and (iv) employees. The questionnaire has 19 items distributed among the four dimensions, in which the respondent indicated their level of satisfaction using the 10-point Likert scale. The questionnaire was available for ten days and obtained 105 respondents. Data were analyzed using the mean and standard deviation of dimensions and items. It was observed that the “employees” dimension obtained the best evaluation, and the item with the best performance was “employees' hygiene”. On the other hand, the “facilities” dimension had the worst performance, and the main item that needs improvement is “access to people with special needs”. After analyzing the data, the main conclusion of the survey was that the level of customer satisfaction with the aforementioned food service is “GOOD”. In the end, improvement suggestions were made for five items considered to be the most critical. For future studies, it is suggested to evaluate the level of customer satisfaction with that service after applying the improvement actions suggested in this work.

Chalcogen bonds are the specific interactions involving group 16 elements as electrophilic sites. The role of chalcogen atoms as sticky sites in biomolecules is underappreciated, and the few available studies have mostly focused on S. Here, we carried out a statistical analysis over 3562 protein structures in the Protein Data Bank (PDB) containing 18 266 selenomethionines and found that Se···O chalcogen bonds are commonplace. These findings may help the future design of functional peptides and contribute to understanding the role of Se in nature.

Buxrugulosides A-E, four lignan glycosides (1-4) and a protocatechuate derivative (5) featuring a rare (N, N-diethyl)methyl amino group at aromatic rings, were obtained from the aerial parts of Buxus rugulosa, which is famous for treating coronary heart disease. Their structures including absolute configurations were elucidated by HRMS, 1D and 2D NMR, and by comparing their CD data with previous reports. Compound 1 was a rare sesquilignan, and all of these compounds were the first example of lignans with (N, N-diethyl)methyl amino group.

Purpose: To determine the relation of choroidal structural parameters and body mass index (BMI) in an adult population. Methods: About 144 eyes of 144 healthy individuals were incorporated. There were four groups according to BMI values: Group 1 (⩽18.5), group 2 (18.6–24.9), group 3 (25.0–29.9), and group 4 (30.0–34.9). The enhanced depth imaging optical coherence tomography images were binarized using Image-J software. Choroidal thickness (CT), circumscribed choroidal area (CCA), luminal area (LA), stromal area (SA), and choroidal vascularity index (CVI) were calculated. Results: Mean subfoveal, nasal, and temporal CT were lower in group 4 rather than group 1 ( p = 0.032, p = 0.001, and p < 0.001, respectively). Mean nasal and temporal CT also showed a decrease in group 4 as compared to group 2 ( p = 0.04 and p = 0.039). Mean CCA and LA were decreased in group 4 in comparison to group 3 ( p = 0.001 and p = 0.001), group 2 ( p < 0.001 and p < 0.001), and group 1 ( p = 0.001 and p < 0.001). Mean SA showed a decrease only in group 3 rather than group 2 ( p = 0.021) and group 1 ( p = 0.008). Mean CVI was decreased in group 3 and group 4 in comparison to group 1 ( p < 0.001 and p < 0.001) and group 2 ( p = 0.002 and p < 0.001). Conclusion: Increased BMI percentile was associated with a decrease in CT and structural parameters.

This communication reports experimental and theoretical evidences of σ‐hole interactions in adducts between nitrogen or oxygen nucleophiles and tetroxides of osmium or other group 8 elements. Cocrystals between pyridine or pyridine N‐oxide derivatives and osmium tetroxide are characterized through various techniques and rationalized as σ‐hole interactions using DFT calculations and several other computational tools. We propose the term “osme bond” (OmB, Om=Fe, Ru, Os, (Hs)) for naming the noncovalent interactions wherein group 8 elements have the role of the electrophile. The word osme is the transcription of ὀσμή, the ancient Greek word for smell that was used to name the heaviest group 8 element in relation to the smoky odor of its tetroxide., σ‐Hole interactions in adducts between nitrogen or oxygen nucleophiles and tetroxides of osmium or other group 8 elements are reported. Cocrystals between pyridine or pyridine N‐oxide derivatives and osmium tetroxide are characterized through various techniques including computational tools. We propose the term “osme bond” (OmB, Om=Fe, Ru, Os, (Hs)) for naming the noncovalent interactions wherein group 8 elements have the role of the electrophile.

Macrolactones constitute a privileged class of natural and synthetic products with a broad range of applications in the fine chemicals and pharmaceutical industry. Despite all the progress made towards their synthesis, notably from seco-acids, a macrolactonization promoter system that is effective, selective, flexible, readily available, and, insofar as possible, compatible with manifold functional groups is still lacking. Herein, we describe a strategy that relies on the formation of a mixed anhydride incorporating a pentafluorophenyl group which, due to its high electronic activation enables a convenient access to macrolactones, macrodiolides and esters with a broad versatility. Kinetic studies and DFT computations were performed to rationalize the reactivity of the pentafluorophenyl group in macrolactonization reactions.

BACKGROUND: There has been a lack of data on injuries in young adults, including university students, in particular medical students. AIM: The current study was conducted to explore the percentage, and related factors of injuries among a group of medical students, who constitute an important risk group for accidents and injuries. METHODS: This exploratory cross-sectional study was conducted in Kasr Al-ainy Medical School. A convenient sample of medical students was chosen. 1300 survey questionnaires were distributed along all academic years, 807 from them were completely retrieved. The questionnaire form was adopted from “Health behavior survey among university students in low- and middle-income countries questionnaire.” Data entry and analysis were carried out using SPSS 21.0. RESULTS: One-quarter reported having a form of injury last year. Falling was the most nominated cause of injuries by the participant students (5,31.3%). Only those who “perceived” their general health as “well” reported being injured significantly more than those who perceived their general health as poor, with a p value = 0.006 and odds ratio of 1.6 (1.1–2.2). Taking drugs was the only factor significantly determining how the injury happened; whether it is intentional or unintentional with a p = 0.01 highlighting that about one-third (5, 31.3%) of those who were intentionally injured were taking drugs. CONCLUSION: Two factors were identified which will increase the understanding of public health of injuries in university communities to design programs for injury prevention programs specifically targeting medical students.

ConspectusThe prediction of crystal structures assembled in three dimensions has been considered for a long time, simultaneously as a chemical wasteland and a certain growth point of the chemistry of the future. Less than 30 years after Roald Hoffmann's statement, we can categorically affirm that the elevation of reticular chemistry and the introduction of metal-organic frameworks (MOFs) significantly tackled this tridimensional assembly issue. MOFs result from the assembly of organic polytopic organic ligands bridging metal nodes, clusters, chains, or layers together into mostly three-periodic open frameworks. They can exhibit extremely high porosity and offer great potential as revolutionary catalysts, drug carrier systems, sensors, smart materials, and, of course, separation agents. Overall, the progressive development of reticular chemistry has been a game changer in materials chemistry during the last 25 years.Such diverse properties often result not only from the selected organic and inorganic molecular building blocks (MBBs) but also from their distribution within the framework. Indeed, the size and shape of the porous system, as well as the location of active sites influence the overall properties. Therefore, in the continuity of achieving the crystallization of three-periodic structures, chemists and crystal engineers faced the next challenge, as summarized by John Maddox: "it remains in general impossible to predict the structure of even the simplest crystallographic solids from knowledge of their chemical composition". This is where rational design takes place.In this Account, we detail three specific approaches developed by our group to facilitate the design and assembly of finely tuned MOFs. All are based on careful geometrical consideration and a deep study and understanding of the existing nets and topologies. We recognized that highly connected nets, if possible, edge-transitive, are ideal blueprints because their number is limited in contrast to nets with lower connectivity. Therefore, we embarked on taking advantage of existing highly connected MBBs, or, in parallel, promoting their formation to meet our requirements. This is achieved by utilizing externally decorated metal-organic polyhedra as supermolecular building blocks (SBBs), serving as a net-coding building unit, comprising the requisite connectivity and directional information coding for the chosen nets. The SBB approach allowed the synthesis of several families of SBB-based MOFs, including fcu, rht, and gea-MOFs, that are detailed here.The second strategy is directly inherited from the success of the SBB approach. In seeking highly connected building units, our group naturally expanded its research focus to nets that can be deconstructed into layers, pillared in various ways. In the supermolecular building layer (SBL) approach, the layers have an almost infinite connectivity, and the framework backbone is fixed in two dimensions while the third is free for pillar expansion and functionalization. The cases of trigonal pillaring leading to rtl, eea, and apo MOFs as well as the quadrangular pillaring leading to a family of tbo-MOFs are discussed here, along with recent cases of highly connected pillars in pek and aea-MOFs.Finally, our experience with highly coordinated MBBs led us to develop a novel way to use them as secondary building units of lower connectivity and unlock the possibility of assembling a novel class of zeolite-like MOFs (ZMOFs). The case of the Zr-sod-ZMOFs designed through a cantellation strategy is described as a future leading direction of MOF design.

Objectives: To investigate the effect of Co-curing versus Staged-curing and No-bonding on retention of different resin-based sealants (RBS). Study design: For shear bond strength (SBS) and microleakage tests, 90 extracted premolars were divided equally into 3 groups (I, II, III). Each group was further subdivided equally into 3 subgroups (a, b, c). No-bonding subgroups did not receive a bonding agent, Staged-curing subgroups received a bonding agent that was cured before sealant application, while Co-curing subgroups received a bonding agent that was cured after sealant application. Seal-it was applied for group I, Helioseal-F for group II and Clinpro for group III. SBS buttons were tested using Instron machine, while microleakage specimens were examined using micro-CT. Results: Clinpro showed the highest SBS values in Staged-curing and No-bonding groups (8.72±2.39, 12.51±3.16) respectively. Staged-curing was significantly greater in SBS values than those for other groups (P

Morphologically, children aged 3-5 years are able to use basic words and rephrases, while children aged 5 years are able to use three word forms (basic words, rephrases and affix words). Syntactically, children aged 3-5 are able to communicate using 2-3 words while children aged 5 years are able to use 2-5 words in communicating.

Monitoring of health status and metabolism of dairy cows is essential for modern milk production. At the current level of productivity of dairy cows, in addition to essential elements, increasing attention must be paid to controlling the exchange of toxic elements, a significant number of which belong to the category of heavy metals. In this regard, the objective of our research was to study the relationship of pools of heavy metals in the body of dairy cows, evaluated according to hair composition and elemental composition of blood serum and milk productivity of animals. Assessment of trace element content in the samples was performed using inductively coupled plasma mass spectrometry (ICP-MS). Fat and protein content in milk was assessed by the FIL-IDF procedure. In order to assess the metabolic load of chemical elements in body of cows, the coefficient of total load Cload was calculated. It allowed us to divide all animals into three groups. Assessment of the content of 25 chemical elements in hair of cows revealed a general regularity of increase in average statistical values of concentrations of some elements with increasing load from 6.9 in group I to 10.7 in group II and 15.8 in group III. As Cload grew from 10.7 in group II to 15.8 in group III, the content of 20 chemical elements in the coat of animals from group III exceeded that in group II. Exceptions were only Ca, K, P, Se, and As. Thus, the productivity of dairy cows turned out to be interconnected not so much with the level of heavy metals (9 elements), but with a wider list of 20–23 chemical elements. Thus, the optimal course of metabolic processes in animal organism, coupled with the highest productivity, is possible when the internal environment of body is saturated with a certain amount of chemical elements. Accordingly, a lack or excess of these substances will be associated with a decrease in the efficiency of metabolism and animal productivity.

Saline stress is a condition that causes changes in physiological performance in several species and even in cultivars of the same species. Thus, this studyaimed to evaluate the physiological performance of black bean cultivars to salt stress. A completely randomized experimental design was used in a factorial scheme with two cultivars (Mataço and BRS Paisano) and five osmotic potentials simulated with sodium chloride solutions (control = 0.0; -0.2; -0.4; -0.6 and -0.8 MPa), in four replications of 50 seeds per treatment. The variables related to germination, first germination count, germination speed index, and shoot length were evaluated. There were significant interactions (p

PurposeThe parent-subsidiary nexus has been explored since the mid-1990s, but the extent to which subsidiaries resemble their parents remains unclear. Therefore, this study examines the performance drivers for subsidiary banks in emerging markets and their parents to determine the similarities between these groups. The findings could help identify key financial performance measures that should be included in global strategies for multinational banks operating in emerging markets.Design/methodology/approachThe study uses data on subsidiaries from 32 countries, including 20 European transitioning countries and 49 parent companies operating internationally from 1996 to 2015. It considers several models that distinguish between units using individual bank effects and the stochastic structure. In a robustness analysis, EU- and non-EU-based institutions are distinguished and long-term historical links between parents' and subsidiaries' countries are considered.FindingsCost control, capital adequacy and asset quality policies have similar importance for parent banks and subsidiaries and are strictly coordinated, whereas the remaining policies allow more flexibility. Subsidiaries in the EU and in countries that were politically and/or militarily influenced by parent countries do not “fall far from the tree”, which signals their strong group-wide integration and coordination.Research limitations/implicationsThis study covers a limited number of emerging market countries due to the limited availability of long-term series data. Future studies should include more countries.Originality/valueThis study identifies key financial measures used on a group-wide basis for performance management while accounting for long-term relations between host and home countries and the geopolitical characteristics of host countries.

OBJECTIVES In Japan, companies are required to implement a "stress check program" to prevent mental health problems in workers. To identify "high-stress" workers, the Brief Job Stress Questionnaire (BJSQ) is recommended. According to the stress check program manual issued by the government, high-stress can be defined using two criteria, either the "sum method" (simply summing the scores for each scales) or the "score converted method" (using converted scores according to the conversion table for each scales). In this study, we examined the differences in results found using these two criteria on "stress check program" data. METHODS We used data of 71,422 workers in 117 companies and organizations who conducted stress checks in 2016. The prevalence of high-stress was calculated by applying the two criteria simultaneously, and the chi-square test was used to compare the proportion of workers with high-stress. We subsequently divided participants into the four following groups and calculated the proportion of each group: group A was defined as having high-stress by both criteria; group B, only by the sum method; group C, only by the score converted method; and group D, not defined as high-stress by either criterion. We compared the average values of stress response among four groups using the Kruskal-Wallis test, and further compared the average values between group B and group C using the Bonferroni method. RESULTS The average age of participants was 43.7 ± 11.1, and 66.8% were males. The proportion of those defined as having high-stress were 11.7% using the sum method and 13.2% using the score converted method; the proportion of high-stress workers was thus significantly higher when using the score converted method (p

The purpose of the work was to study the effect of high doses of superphosphate on the yield of forage beans and the composition of phosphates in dark gray forest soil. Research methods. The studies were carried out in a microfield experiment. Doses of superphosphate are calculated taking into account the increase in the phosphorus content from medium to very high. The total phosphorus content was determined after calcining the soil, and the mineral group was determined in the natural state of the soil in an extract of 0.2n sulfuric acid, the fractional composition was determined by the method of S. Chang and M. Jackson. Results. High doses of superphosphate (the degree of phosphorus supply is high and very high) without the introduction of nitrogen and potassium fertilizers significantly reduce the productivity of beans. The optimal content of mobile phosphorus is an increased degree of supply (101–150 mg/kg according to Kirsanov). High doses of superphosphate double the total phosphate content in relation to the original soil, mineral phosphates make up 77 %, organophosphates – 22.8–23.3 %. Analysis of the fractional composition of mineral phosphates showed that the use of water-soluble phosphorus fertilizers increases the amount of phosphates of all fractions. The fraction of loosely bound phosphates increases from 5 mg/kg of soil (medium supply) to 14 mg/kg at a very high level. From the total amount of mineral phosphates, calcium phosphates occupy 20–23 %, aluminum phosphates – 12.5–14.9 %. The share of ferrophosphates practically does not change with the dose of superphosphate and is 25.3–25.7 %. The fraction of poorly soluble phosphates is the most significant: with an increased degree of supply, the content of phosphates is equal to 438 mg / kg and increases with a very high degree of supply up to 529 mg/kg of soil, this is 37.1–38.8 % of the total amount of the mineral group of phosphates. The scientific novelty lies in the calculation of the dose of phosphorus fertilizer, taking into account the stepwise transition from one degree of provision to another, from medium to high, high and very high. This approach to calculating the doses of fertilizers makes it possible to differentiate the doses of nitrogen-potassium fertilizers.

The population of this research was all tenth grade students of SMA Muhammadiyah Pagaralam, consist of 259 students. Two classes were chosen as the sample and they divided into experimental class and control class that consist of 32 students each classes. The sample were taken by using purposive sampling. Quasi experimental method was used in this research. The result of pre-test and post-test in experimental class and control class were compared by using independent sample t-test, in term of reading aspects. The value of t-obtained was 4,628, at the significance value p

In this research, two software packages are developed to be connected with MCNP and NJOY to obtain and extract nuclear cross sections. The first (main) software package was coupled with the MCNPX code to automatically run it to obtain cross sections of isotopes for multi-group and a wide range of incident neutron energies. It was also coupled with the second software package entitled AutoNJOY, which is directly coupled with the NJOY code, to automatically run it and obtain the cross sections of isotopes at any temperature for any reaction. The results obtained by the AutoNJOY were automatically transferred to the first software package, and the results were compared with those obtained by the MCNPX code, and the graphs of isotope cross sections were plotted in energy. The first software package is also able to analyze the microscopic cross sections obtained by the AutoNJOY and draws the graph of the cross section vs. energy. It is also able to be connected to the ACE library directly and reads microscopic cross sections of all the elements and their isotopes that have the various ZAID. It was observed that from the thermal neutron range to the fast, the cross sections of isotopes obtained by the AutoNJOY were nearly similar to the results obtained by the first software package, and the derived graphs of both methods approved with each other.

OBJECTIVE The aim: This study evaluates the effect of adding silanized halloysite nanotubes to the polymethylmethacrylate (PMMA) resin on its hardness, impact strength, transverse strength. PATIENTS AND METHODS Materials and methods: Three groups of acrylic resin were prepared, one group without HNTs, was used as a control group (A). The other two groups contained 0.3% (B), 0.6% wt of silanized halloysite nanotubes (C). For each one, hardness, impact strength and transverse strength were measured. One-way ANOVA and Tukey's test were used for comparison. RESULTS Results: Regarding to the impact test, there was no significant difference between 0.3% concentration and the pure (control) group while 0.6% concentration had significant decrease compared to the pure group and so between the 0.3% group 0.6% group. For the hardness test, the 0.3% group had no significant difference with the pure group and a significant difference between group 0.6% group and the pure group while there was a no significant decrease between the 0.3% and 0.6% group with the higher hardness mean in the 0.3% compared to 0.6% group. For the transverse strength, both 0.3% wt concentration and 0.6% concentration showed significant difference compared to the pure group and also between each other with the lowest impact strength in 0.6% group followed by 0.3% group with the highest transverse strength in the pure group. CONCLUSION Conclusions: The silanation of halloysite nanotubes reduces the mechanical properties of the heat-cured acrylic denture base material. The more concentration of silanazed halloysite nanotubes is added, the more weakening occurs in the acrylic material relating to the hardness, transverse strength and impact strength.
