Aquifers are severely polluted with organic and inorganic pollutants, posing a serious threat to the global ecological system's balance. While various traditional methods are available, the development of innovative methods for effluent treatment and reuse is critical. Polymers have recently been widely used in a variety of industry sectors due to their unique properties. Biopolymers are a biodegradable material that is also a viable alternative to synthetic polymers. Biopolymers are preferably obtained from cellulose and carrageenan molecules from various biological sources. While compared with conventional non-biodegradable polymeric materials, the biopolymer possesses unique characteristics such as renewability, cost-effectiveness, biodegradability, and biocompatibility. The improvements towards the biopolymeric (natural) membranes have also been thoroughly discussed. The use of nanofillers to stabilise and improve the effectiveness of biopolymeric membranes in the elimination of organic pollutants is one of the most recent developments. This was discovered that the majority of biopolymeric membranes technology consolidated on organic pollutants. More research should be directed toward against emerging organic/persistent organic pollutants (POP) and micropollutants. Furthermore, processes for regenerating and reusing utilized biopolymer-based carbon - based materials are emphasized.

Current health and environmental concerns about the abundance and drawbacks of municipal wastewater as well as industrial effluent have prompted the development of novel and innovative treatment processes. A global shortage of clean water poses significant challenges to the survival of all life forms. For the removal of both biodegradable and non-biodegradable harmful wastes/pollutants from water, sophisticated wastewater treatment technologies are required. Polymer membrane technology is critical to overcoming this major challenge. Polymer matrix-based nanocomposite membranes are among the most popular in polymer membrane technology in terms of convenience. These membranes and their major components are environmentally friendly, energy efficient, cost effective, operationally versatile, and feasible. This review provides an overview of the drawbacks as well as promising developments in polymer membrane and nanocomposite membranes for environmental remediation, with a focus on wastewater treatment. Additionally, the advantages of nanocomposite membranes such as stability, antimicrobial properties, and adsorption processes have been discussed. The goal of this review was to summarize the remediation of harmful pollutants from water and wastewater/effluent using polymer matrix-based nanocomposite membrane technology, and to highlight its shortcomings and future prospects.

The implementation of the tax dispute trial is regulated by the Law of The Republic of Indonesia No.14/2002 concerning Tax Court article 4 which states that the tax dispute trial conducted by the tax court can be held in Jakarta and other regions if it is deemed necessary. The problem arises when local taxpayers whose tax dispute trials are held outside Jakarta hire a tax consultant from Jakarta, the taxpayer must bear the transportation and accomodation costs of the tax consultant team who come to the region where the trial is held, such as airline tickets, hotels, and other costs during the trial. The tax court institution also bear the travel cost of the official team of tax court judges who will lead the trial, because the judge who leads the trial comes from Jakarta. This study aims to analyze the implementation of tax dispute trial held outside Jakarta in terms of the principle of ease of administration. The results show that in terms of the four ease of administration principles, only the principle of efficiency is not fulfilled. This is due to the high costs incurred by taxpayers and tax courts side to conduct tax dispute trials outside Jakarta.

“Explaining the grammar principles is a explain of the basic sources from which its phenomena were taken and its rulings are extrapolated from it, and it is unavoidable for every Arab grammar student to stand on it and consider it. The grammarians of Basrien were the first to reexplain these principles and stick to them. They have their own grammatical method and they infer this evidence. The Basroun relies on hearing such as the Qur’anic verses, the hadiths of the Prophet and the words of the Arabs like the Kufic, but they require many conditions, especially in the hadith and the words of the Arabs, as well as by analogy and consensus.”

Functionalized carbon nanoparticles (CNPs) show great promise for various drug delivery applications. These CNPs have distinct physical and chemical properties, such as low solubility, very high conductivity, and drug loading capability, and are thus important nanodevices for cancer therapy. Cancer is a highly challenging disease, because its therapy involves distinguishing diseased cells from healthy ones. This study aimed to determine the ability of CNPs conjugated with a chemotherapeutic agent to inhibit cancer cell growth. We developed two models to determine the effectiveness of paclitaxel (PTX) as an antitumor agent bonded to single-walled carbon nanotubes (SWCNTs) varying in radius (r). The models were used to mathematically evaluate the energy arising from the PTX–SWCNT interaction. The first model divided the PTX molecule into 15 subcomponents: 4 imidazole rings, 1 group of atoms forming a cylindrical nanotube, 6 methyl groups (small spheres represented as individual CH3 molecules), 3 carboxyl groups (medium-sized spheres represented as individual CO2 molecules), and 1 large sphere. In the second model, PTX was modeled as a spherical cage with a spheroidal structure. Next, we determined the minimum interaction energy between each subcomponent and an SWCNT of radius r, and then summed the interactions to determine the total energy (E). The numerical results indicated that SWCNTs can be loaded with PTX. We also determined the critical nanotube r required for acceptance of the PTX molecule. We believe that the findings of this research will encourage the development of new nanodevices capable of delivering larger amounts of drugs, genes, and proteins.

Coronavirus (COVID19) is an infectious disease that attacks the human body, particularly within the respiratory regions, e.g., nasal and lung tissues. COVID19 infection is classified into three different stages: mild, moderate, and severe. Recovery from the first two stages can mostly be achieved without special treatment, but these stages can lead to death for older people and those who have underlying medical conditions, such as diabetes, chronic-respiratory disease, HIV, and cardiovascular disease. COVID19 prefers to attack the tissues and membranes of the respiratory system, especially those found in the nose, throat, and on the external surface of the lungs. Aquaporins (AQPs) are a large family of integral biomembranes that facilitate transport of water and small biomolecules between cells. The current work develops two scientific sub-models, i.e., biological and statistical. The biological model is aimed at investigating the realistic mechanism of bio-interaction between the two types of COV and different AQP protein channels. This model is obtained mathematically by evaluating the magnitude of the potential energy arising from SARSCOV and COVID19 penetrating the cavity of the AQP protein channels located on the external surface of human cells. We use an exponential function to estimate the transmission rate of COVID19 with respect to time in different territories. Additionally, we observe that temperature and direct contact play major roles in determining the number of infected cases, and consider relative humidity as a secondary factor. Our results show that AQP1, AQP3, and AQP4 are the most favorable tissues for COVID19 spread because their pH exceeds 6.5. A mathematical model is developed that describes the behavior of the COVID19 outbreak in terms of temperature (μ) and direct contact (α) rate.

Carbon nanomaterials have received increasing attention in drug delivery applications because of their distinct properties and structures, including large surface areas, high conductivity, low solubility in aqueous media, unique chemical functionalities and stability at the nano-scale size. Particularly, they have been used as nano-carriers and mediators for anticancer drugs such as, combination with Cisplatin, Camptothecin and Doxorubicin. Cancer has become the most challenging disease because its sophisticated therapy and classified as one of the top killers according to the World health organization records. The aim of the current work is to study and investigate the mechanism of combination between single-walled carbon nanotubes (SWCNTs) and the fullerene derivatives (C N -[OH] β ) as mediators, and anticancer drugs for photodynamic therapy directly to destroy the infected cells without damaging the normal ones. Here, we obtain a bio-medical model to determine the efficiency of usefulness of Doxorubicin (DOX) as an antitumor agent conjugated with SWCNTs with variant radii r and fullerene derivative (C N -[OH] β ). The two sub-models are obtained mathematically to evaluate the potential energy arising from the DOX-SWCNT and DOX-(C N -[OH] β ) interactions. DOX modelled as two-connected spheres, small and large, each interacting with different SWCNTs (variant radii r ) and fullerene derivatives C N -[OH] β , forming based on the number of carbon atoms (N) and the number of Hydroxide molecules (OH) ( β ), respectively.

Dari hasil ini dapat disimpulkan bahwa game yang dikembangkan dapat dinyatakan sangat layak digunakan dalam kegiatan pembelajaran serta bermanfaat bagi guru dan siswa. The background of this study is the low score of physics subject indicated by the result of 2019 national exam, where physics average score is in the second-lowest place just after math. One of the solutions to this problem is to raise the students’ intensity on learning by themselves, continued by doing some exercise. To increase students learning intensity, it is necessary to attract the student to study. Educational games is one way to attract students’ interest in learning. In addition to improving learning outcomes, educational games can also increase students’ motivation and activeness in learning. An educational games is often interesting and prevent students to get bored. Therefore, this study aims to produce a physics educational game for dynamic fluid material that is suitable to be used for class XI students both inside and outside the classroom. This study uses 4-D development model, alongside with the SDLC waterfall model for software development. The game was validated by learning material and media experts to decide whether the game is valid to used in learning, using a questionnaire with Likert scale. The validation results 90% score by the learning materials expert and 85% by the media expert. From this result, the game can be categorized as very valid and proper to use. Afterward, the game is tested by high school students and physics teachers in order to know the readability, resulting score of 83.57% from the students and 91.67% from the teacher. Thus, it can be concluded that the developed game is valid and can be used in learning.

Background: Diabetic ketoacidosis (DKA) is one of the life-threatening acute complications of diabetes mellitus that mainly occurs in type 1 diabetes mellitus (T1DM). This study aimed to determine the socioeconomic factors associated with DKA in patients with T1DM in Basrah. Methods: A cross-sectional study including patients with T1DM who were admitted due to DKA or any other complaint in any of the teaching hospitals in Basrah, from February to October 2017. Data collection from each patient or their parents using a questionnaire was designed to capture personal, social, and disease-related factors. Results: One hundred forty-seven patients were involved in this study. They were compared with different factors to assess correlations with the risk of DKA. Younger age, underweight, being without a job, low personal and/or mother educational level, travel, home glucose monitoring less than 7 times a week, uncontrolled HbA1c and insulin stoppage as a cause of DKA regardless of the reasons to stop were associated with an increased risk of DKA. On the other hand, own home, availability of a glucometer for checking glucose, basal-bolus insulin regimen, insulin supply, and education at a tertiary center, correct injection technique whoever injected the insulin and dietary adherence, all were associated with a decreased risk of DKA. Other factors like gender, marital status, smoking status, father educational level, residency, income, personal home area, the frequency of HbA1c checking, and family history of diabetes were not associated with a significant effect on the DKA risk. Conclusions: Multiple socioeconomic factors interact to play a vital role in the development of DKA among patients with T1DM in Basrah.

This study aims to identify blood biomarkers for rapidly predicting progression and severity assessment of COVID-19 in type 2 diabetic (DM) and non-DM (NDM) patients. Among 211 hospitalized patients suspected of COVID-19, 98 were confirmed COVID-19 by rRT-PCR. The COVID-19 positive group contained 58 DM and 40 NDM patients with total death 9 of which 7 were males and 6 were DM, indicating males and DM individuals as more susceptible to COVID-19. Blood biomarkers notably serum ferritin, CRP, D-dimer, ALT, troponin I, and Hb1Ac were significantly (p < 0.05) higher in COVID-19 patients. Ferritin and HbA1c levels were significantly (p < 0.05) higher in DM than NDM COVID-19 patients. The present study suggests that ferritin and HbA1c levels for DM patients, and ferritin, D-dimer, ALT for NDM patients could be routinely used as biomarkers for progression and severity assessment of COVID-19. CRP and Troponin-I could be the predictor only for poor prognosis of COVID-19. [ABSTRACT FROM AUTHOR]

Objectives: In 2013, the World Health Organization (WHO) recommended new criteria for diagnosing gestational diabetes mellitus (GDM). Our study aimed to compare the incidence of GDM and its complications among Omani pregnant women using the new diagnostic criteria compared to previous criteria published in 1999. Methods: This retrospective cohort study was conducted between January and December 2016 at the Bawshar Specialized Polyclinic in Muscat, Oman. A total of 613 Omani women were included in the study. Baseline maternal characteristics such as age, body mass index, parity, and socioeconomic status were recorded in addition to maternal and neonatal outcomes. Results: Based on the current diagnostic criteria, the incidence of GDM was 48.5% (n = 297); however, this dropped to 26.4% (n = 162) when applying the old criteria. Moreover, rates of maternal complications including polyhydramnios (5.6% vs. 4.6%), pregnancy-induced hypertension (3.2% vs. 1.5%), and preterm delivery (3.2% vs. 1.5%) were slightly higher among women with GDM diagnosed using the latest criteria. However, these differences were not statistically significant. Neonatal complications were also slightly more frequent among the first group, without any significant differences. Conclusions: The incidence of GDM among Omani women rose dramatically when utilizing the latest WHO diagnostic criteria, owing to a lower fasting blood glucose cut-off value. In addition, a comparison of the frequencies of maternal and neonatal complications supports the validity of the new criteria. These findings should be taken into consideration by decision-makers in Oman when planning antenatal and postnatal services.

The new generations of nano-devices successfully apply with great promise as drug carriers in the treatment of different diseases. The proposed model aims to determine the pharmacological targets and evaluate the bio-safety of usefulness of carbon nanotube conjugated with two different antiviral compounds, Acetylcholine and Ravastigmine, for treating Alzheimer disease. We also obtain the medicinal model mathematically to evaluate the interaction energy arising from encapsulation of each antiviral compound inside the single-walled carbon nanotube. Acetylcholine is modelled as two-connected spheres, while Ravastigmine has two possible structures which are an ellipsoid and cylinder, all interacting with the interior wall of single-walled carbon nanotubes with variant radii rc . Our calculations show that the single-walled carbon nanotube of radius rc greater than 3.391 A that will accept both drugs which are quite closer to the recent findings.

In the cation of the title compound [systematic name: (RS)-4-(3-carboxy-1-ethyl-6,8-difluoro-4-oxo-1,4-dihydroquinolin-7-yl)-2-methylpiperazin-1-ium 2,4,6-trinitrophenolate], C17H20F2N3O3+·C6H2N3O7−, the piperazine ring adopts a slightly distorted chair conformation and contains a protonated N atom. An intramolecular O—H...O hydrogen bond occurs in the cation. The dihedral angles between the mean planes of the six-atom piperazine ring and the 10-atom fused ring system is 43.3 (5)°. The picrate anion interacts with the protonated N atom of an adjacent cation through a bifurcated N—H...(O,O) three-center hydrogen bond. Strong N—H...O hydrogen bonds in concert with weak π–π stacking interactions [centroid–centroid distance = 3.6460 (14) Å] dominate the crystal packing, creating a two-dimensional network structure along [011].

Crystallography ,QD901-999 - Abstract
The title salt, 2C16H15F3N3OS+·C6Cl2O42−, is composed of two independent cations of a lansoprazole {systematic name 2-([3-methyl-4-(2,2,2-trifluoroethoxy)pyridin-2-yl]methylsulfinyl)-1H-benzo[d]imidazole} intermediate and a dianion of chloranilic acid. In the cations of the lansoprazole intermediate, the dihedral angles between the least-squares planes of the pyridine and benzimidazole rings are 11.1 (6) and 13.1 (5)°, respectively. The dihedral angles between the mean plane of the benzene ring in the chloranilic acid dianion and the pryidine and benzimidazole rings of the two lansoprazole intermediate groups are 71.8 (1)/80.5 (7) and 74.2 (4)/74.8 (6)°. In addition to ionic bond interactions, the lansoprazole intermediate and chloranilic ions are connected by strong N—H...O hydrogen bonds, which produce a set of extended O—H...O—H...O—H chains along the b axis in the (011) plane. In addition, weak C—H...O, C—H...F, N—H...Cl and π–π [centroid–centroid distances = 3.5631 (15), 3.8187 (13), 3.7434 (17) and 3.842 (2) Å] intermolecular interactions are observed, which contribute to crystal packing stability.

Crystallography ,QD901-999 - Abstract
The structure of the title compound, C19H28O2, has been redermined at 295 (2) K, with much improved precision. The structure and molecular packing of the title compound was first reported by Coiro et al. [Acta Cryst. (1973). B29, 1404–1409] by means of potential-energy calculations. The cell parameters in this study differ considerably in space group C2. It is a derivative of testosterone and consists of a cyclopentanone ring (A) fused to to successive cyclohexane (B and C) and cyclohexanone (D) rings. The three cyclohexanone rings are in slightly distorted boat configurations and the cyclopentanone ring is a distorted half-chair. The crystal packing is stabilized by weak intermolecular C—H...O interactions involving O atoms from each of the cyclohexanone and cyclopentanone rings and H atoms from each of their respective rings.

Crystallography ,QD901-999 - Abstract
The title compound, C18H23N2+·Cl−, is a non-merohedrally twinned salt [domains 0.9288 (3) and 0.0712 (3)] which crystallizes with four independent cation–anion pairs in the asymmetric unit. The seven-membered ring in each of the cations adopts a boat conformation, thus creating a butterfly effect within the ring system. The average value of the dihedral angle between the two aromatic rings in the four cations is 57.1 (1)°. The crystal packing is stabilized only slightly by a collection of intermediate N—H...Cl hydrogen-bonding interactions, which produce a weak, but cooperative, infinite, one-dimensional, intermolecular hydrogen-bond network along the a axis. A MOPAC PM3 computational calculation gives support to these observations.

Crystallography ,QD901-999 - Abstract
The title compound, C16H15N5, crystallizes with two independent molecules (A and B) in the asymmetric unit. The dihedral angles of the pyrimidine ring with the benzene and pyridyl rings are 22.3 (1) and 53.2 (9)°, respectively, in molecule A, and 6.8 (1) and 11.6 (9)° in molecule B. The crystal packing is influenced by the collective action of weak intermolecular N—H...N hydrogen bonds, a π–π stacking interaction between neighbouring pyridyl rings of molecule A [centroid–centroid distance = 3.8395 (10) Å] and C—H...π interactions.

The title compound [systematic name: 3-(10,11-dihydro-5H-dibenzo[b,f]azepin-5-yl)-N,N,2-trimethylpropan-1-aminium hydrogen maleate], C20H27N2+·C4H3O4−, a maleate salt of trimipramine, crystallizes with four independent cation–anion pairs in the asymmetric unit. The trimipramine cation contains a seven-membered azepine ring with two fused benzene rings whose mean planes are separated by 51.7 (1)°. Intermolecular N—H...O and intramolecular O—H...O hydrogen bonds pack the ions into chains along [101]. Additional weak intermolecular C—H...O interactions help to influence the twist angles of the mean planes of the benzene rings fused to the azepine ring in the cation. A geometry-optimized MOPAC AM1 theoretical calculation supports these observations.

In the title compound, C21H15F3N2, the benzene ring bonded to the central C atom forms dihedral angles of 77.5 (7) and 89.0 (5)°, respectively, with the remaining two benzene rings. Weak intermolecular C—H...F hydrogen bonds link the molecules into chains propagated in [101]. The crystal packing exhibits weak π–π interactions as evidenced by relatively short distances between the centroids of the aromatic rings [3.820 (7) and 3.971 (5) Å]. A MOPAC PM3 optimization of the molecular geometry in vacuo supports a suggestion that intermolecular forces have a significnt influence on the molecular conformation in the crystal.

The chlorimipraminium cation contains two benzene rings (one with a chloro substituent) fused to a V-shaped seven-membered azepine ring whose mean planes are separated by 61.1 (0) and 66.5 (8)° with a 3-(dimethylamino)propyl group extending away from the apex of this ring. In the picrate anion, the mean planes of the two o-NO2 groups in each anion are twisted by 3.7 (2)/31.9 (3) and 31.3 (1)/11.4 (0)°, respectively, with respect to the mean plane of the six-membered benzene ring. The phenolate O atoms are bent slightly away from the mean plane of the benzene ring. The mean planes of the p-NO2 groups are twisted by 6.6 (1) and 2.88°, respectively, from the mean plane of the benzene ring. The crystal packing features bifurcated N—H...(O,O) intermolecular hydrogen-bond interaction, which connects each cation–anion pair. Additional π–π ring and C—H...π weak intermolecular interactions are also observed.

Crystallography ,QD901-999 - Abstract
The crystal structure of chloranilic acid, C6H2Cl2O4, was first described by Andersen in 1967 [Andersen, E. K. (1967). Acta Cryst. 22, 188–191] at room temperature using visually estimated intensities. Taking into account the importance of the title compound, we have redetermined the structure at 100 (1) K. The approximately planar molecule [the maximum deviation from the mean plane through the ring is 0.0014 (9) Å for the ring atoms and 0.029 (3) Å for the other atoms] occupies a special position, lying across the center of symmetry. In the crystal structure, a two-dimensional hydrogen-bonded network sustained by O—H...O interactions runs approximately parallel to [101]. The two-dimensional layers are further packed in a parallel fashion, stabilized by Cl...Cl interactions [Cl...Cl = 3.2838 (8) Å, C—Cl...Cl = 152.96 (6)°].
