The Dilemma of Representation: UN Rules and Regulations in Addressing Conflict over Afghanistan's Seat in UN General Assembly
Authors: Mairajuddin Aminzai , Hakimudin Manzanay 
Published: May 2023

Aim: The primary aim of this study was to clarify and describe the conflict between the officials of the Islamic Republic and the Islamic Emirate regarding Afghanistan's representation in the United Nations. The study also sought to propose a solution to this conflict in line with the principles and rules of the United Nations and the international community, which can be presented to the relevant parties.

Methods: Since this study had a purely bibliographic aspect, descriptive and analytical methods were used. Legal documents, declarations, and resolutions of the United Nations were used to investigate the issue of Afghanistan's representation in the United Nations.

Results: The dispute over the seat of Afghanistan in 2021 is not a novel phenomenon since a similar dispute had arisen between the governments of that time in 1997. After the fall of Kabul in August 2021, both the former republic and the Taliban government requested the United Nations to hand over the seat of Afghanistan to their nominated representatives. The Credentials Committee of the General Assembly decided that the assistant of the former representative should continue to represent Afghanistan in the United Nations.

Conclusion: The new representative does not have the right to assume the position of the United Nations Organization until acquiring national and international legitimacy, establishes a government based on the rule of law, and takes concrete steps toward the development of human rights.

Recommendation: As the current government of the Taliban has fulfilled the conditions of recognition of governments according to international law, the United Nations should hand over Afghanistan's seat to them. On the other hand, the Taliban should use lenience in the issues that the United Nations insists on and establish a government according to the will of the people.

Published: May 2023

Cirsium arvense is one of the worst weeds in agriculture. As actual herbicides are not very effective and not accepted by organic farming or in order to reduce the cantity of herbicides used, possible biocontrol agents have been investigated since many decades. The work carried out aimed at obtaining and assessing the herbicidal potential of bacterial preparation based on Pseudomonas syringae pv. tagetis (PST) for biological control of Cirsium arvense (L.) Scop. Silibase 2848P, an organosilicone surfactant, was required to facilitate PST penetration into creeping thistle leaves. The experiments were conducted under controlled conditions (growth chamber) to determine the concentration of Silibase 2848P required for the maximum penetration of PST into creeping thistle leaves. As well as to evaluate disease incidence in emerging leaves, and to quantify the effects of inundative foliar application on fresh and dry weights of shoots. In field conditions, efficacy of PST applications was assessed in terms of disease incidence and effect on shoot height, number of flower buds and survival of C. arvense. Maximum disease severity were recorded when PST was applied at a concentration of 10 x 108 cfu/ml + Silibase 0.3%.

With climate change evident, the possibility opens up of introducing into production a species that, although not characterized by high yield, nevertheless offers some other benefits for both the environment and man. One of these species is mountain clover (Trifolium montanum L.), a species widespread around European in the past, but due to agricultural activities its habitat has become fragmented and areas of mountain clover impaired. In the present study, the collection of nine natural populations of mountain clover originating from different parts of the hilly-mountainous areas of Serbia was tested in field conditions. We analysed different morphological traits (green plant biomass, stem length, internode number, number of lateral branches, leaf length and leaf width), dry matter quality traits (content of crude proteins, crude fibre and crude fat) as well as secondary metabolites (total phenolic content, flavonoid contents and antioxidative activity). We collected morphological data and plant samples during 2011 and 2012. We performed descriptive statistics to provide basic information about variables in the dataset, then calculated Shannon-Weaver diversity index (H’) and performed two-way ANOVA and principal component analyses (PCA). Analysing the broad range of data collected during two years, we found considerable morphological and chemical diversity amongst the collection of mountain clovers from central Serbia. Mean coefficient of variation (CV) in the morphological dataset ranged from 18% (stem length) to 57.6% (plant biomass) in 2011 and from 16.5% (leaf length) to 70.6% (stem number) in 2012. Dry matter (DM) parameters displayed the lowest CV, ranging from 6.1% (crude proteins) to 14.8% (crude fat), indicating that these parameters were less discriminative within the study collection. Over all populations, average crude protein content was 19.5%, and average crude fibre content was 27.3%. Total phenolic contents (expressed as gallic acid equivalent, GAE) ranged from 49.8 to 89.7 mg GAE g-1 DM, and flavonoid contents (expressed as rutin, Ru, equivalent) ranged from 66.8 to 142 mg Ru g-1 DM. Average antioxidative activity expressed in terms of IC50 values ranged from 177 to 426 mg ml-1 of methanol extract.

Antibiogram and Resistant Gene (Gentamicin and Estended Beta-lactam) Profile of Escherichia coli Isolated from Yoghurt
Authors: K. Robinson, Victor , Owhonka Aleruchi, , Chibuike Okafor, Afam , Ijeoma Ahuokpo, Happiness , Happiness Ipalibo, Christopher
Published: May 2023

The antibiotic susceptibility profile of Escherichia coli isolated from yoghurt samples within the Port Harcourt metropolis was investigated. Yoghurt samples (sachets and bottled yoghurts) were randomly bought from vendors within Port Harcourt and were transferred in an ice-pack container to the microbiology laboratory, at Rivers State University where they were analyzed. Enumeration and isolation of faecal coliform were done using Eosin Methylene Blue Agar (EMB). Aliquot from 10-1 dilution of the sample was aseptically transferred into dried EMB agar plates in duplicates, spread evenly using a sterile bent glass rod and incubated at 45℃ for 24-48 hours. After incubation, plates were observed for growth and counts were recorded for the determination of colony forming unit while colonies on the plates were sub-cultured on freshly prepared nutrient agar plates. Morphological, gram reaction and biochemical tests were used for identification. The Kirby Bauer disk diffusion test on Mueller-Hinton agar using commercially prepared antibiotics was used in determining the antibiotic susceptibility profile of the isolates. Results showed that the mean range of the faecal coliform load of the yoghurts was 0.0-6.0×102 CFU/mL. More so, out of the samples analyzed, only two samples were positive for E. coli. Results of the antibiotics susceptibility showed that all five E. coli isolates were resistant to more than two antibiotics and exhibited multi-drug resistance. Some of the isolates possessed Inc-P and TEM-resistant genes. Although they were completely susceptible to Nalidixic acid, Levofloxacin, Ceftriaxone and Ofloxacin antibiotics. More so, 40% resistant isolates had a MAR index of 0.2, while the other 40 and 20% resistant isolates had a MAR index of 0.5 and 0.3, respectively. Contamination of the samples could be through manufacturing or packaging and distribution processes. Thus, good manufacturing practice is highly recommended.

Aims: Several parts of medicinal plants have been known to have many health benefits. One of those plants is the Crinum glaucum (CG) bulb. Therefore, this research was undertaken to investigate the therapeutic role of an aqueous extract of CG bulb (aeCGb) against lipopolysaccharide (LPS)-induced haematological and hepatic enzyme alterations in male and female rat models.

Study Design and Methodology: Twenty-five male and twenty-five female rats were divided randomly into five groups (n = 5) each. Group 1 is the control group. Group 2 was administered with 1000 mg/kg body weight of aeCGb. Group 3 was exposed to 4 ml/kg body weight of LPS for 4 hours. Group 4 was administered LPS (4 hours) and 1000 mg/kg body weight of aeCGb. Group 5 was administered 1000 mg/kg body weight of aeCGb and LPS for 4 hours. The albumin, total protein, bilirubin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and gamma-glutamyl transferase (hepatic enzyme) concentrations and haematological parameters were analysed spectrophotometrically.

Results: The hallmark of LPS is its ability to decrease the concentration of hepatic enzymes and the levels of haematological parameters, as observed. The levels of albumin, total protein, and direct and total bilirubin were significantly (P≤ .05) increased in the aeCGb-treated groups. However, treatment with aeCGb reverses the damaging effect of LPS on hepatic enzyme concentration.

Conclusion: The results suggest that aeCGb has a therapeutic role in the LPS-induced alterations by correcting the concentration of hepatic enzyme function as well as regulating the levels of haematological parameters.
Factors Determining the Financial Performance of Public Sector Banks in India
Authors: Nalliboyina Suresh Babu , Chalam G. Venkata
Published: May 2023

Now, an attempt is made in this paper to examine the determinants of profitability in Indian public sector banks during the period 2010-11 to 2021-22. For this purpose, a sample of 12 public sector banks listed in NSE & BSE has been taken. Multiple Linear Regression Analysis has been used to investigate the impact of independent variables such as a bank’s asset size (Size), capital adequacy ratio (CAR), cost to income (CTI), net non-performing assets (NPA), credit risk (CrR), credit deposit ratio (CDR),economic growth (GDP) and consumer price index (CPI) inflation on key bank profitability indicators, i.e., return on assets (ROA), return on equity (ROE) and net interest margin (NIM)as dependent variables, separately.

The main findings show that bank asset size, cost to income, net non-performing assets, credit deposit ratio, and inflation are negatively related to ROA, ROE, and NIM. Credit risk and economic growth (GDP) have a positive impact on ROA, ROE, and NIM. While the capital adequacy ratio hurt ROA and NIM except for ROE. Even though overall explanatory and macroeconomic factors have a significant 5 percent effect on ROE and NIM as denoted by F-statistics value. Moreover, the banking sector has benefited weakly significantly from both economic growth and the inflationary environment. It is also suggested that if banks concentrate on these variables, they would be able to generate better profitability in the present globalized era. These findings are of value to both academicians and policymakers.

Methodology: Grey prediction model GM (1,1), Holt-winter seasonless exponential smoothing model and autoregressive moving average ARIMA model were used to construct an order weighted arithmetic mean combination model induced by IOWA with the minimum sum of error squares. Then, by building new weights, three individual forecasting models and combination forecasting models are used to forecast the income gap between urban and rural residents in the next five years.

Results: The results show that the accuracy of the combined prediction model is significantly better than that of the single prediction model.

Conclusion: It can be known that the income gap between urban and rural residents will widen further in the future, with an average growth rate of 4.55%.

This study was carried on solid waste management in Sher-Kashmir University of Agricultural Science and Technology Kashmir. It is noted that the advantages in managing solid waste at institutional level such as university because of its unique characteristics also influences the waste management needs and strategies. This paper outlines findings from a yearlong study through surveys, field investigations, including on-site waste measurements and questionnaire on institutional solid waste management. It was discovered that the waste's content was primarily organic in content, suggesting a strong disposing potential in terms of organic manure or biogas production through scientific digestion and composting. The study revealed that maximum contribution to organic waste in the form of food waste was from messes of the hostels (53.32 T). That can be biodegradable managed and properly disposed, hence make a significant change in the waste management system. Hostels also generate 17.77T of plastic waste annually that needs processing through scientific recycling techniques on sustainable basis. The study found that scientific segregation of trash might significantly improve solid waste management at other universities with a comparable environment.

Authors: Alsheweir Nourah
Published: May 2023

Flexible working arrangements are becoming increasingly popular. Many organizations implement it to provide employees the flexibility to decrease work nonwork conflict and enhance their psychological well-being. In return, organizations expect higher commitment and productivity from their employees. This paper aims to critically appraise what is known in the scientific literature about the effects of flexible working intervention on both work nonwork conflict and employees’ psychological well-being. Using the guidelines provided by the Center for Evidence-Based Management for Critically Appraised Topics.

The assessed literature indicates that flexible working arrangements can reduce work-nonwork conflict depending on the type of flexibility the organization adopts. Additionally, introducing different flexible working arrangements improves employees' psychological well-being.

Importance

Little is known about how out-of-pocket burden differs between Medicare and commercial insurance for ultra-expensive drugs.

Objective

To investigate out-of-pocket spending for ultra-expensive drugs in the Medicare Part D program vs commercial insurance.

Design, Setting, and Participants

This was a retrospective, population-based cohort study of individuals using ultra-expensive drugs included in a 20% nationally random sample of prescription drug claims from Medicare Part D and individuals aged 45 to 64 years using ultra-expensive drugs included in a large national convenience sample of outpatient pharmaceutical claims from commercial insurance plans. Claims data from 2013 through 2019 were used, and data were analyzed in February 2023.

Main Outcomes and Measures

Claims-weighted mean out-of-pocket spending per beneficiary per drug by insurance type, plan, and age.

Results

In 2019, 37 324 and 24 159 individuals using ultra-expensive drugs were identified in the 20% Part D and commercial samples, respectively (mean [SD] age, 66.2 [11.7] years; 54.9% female). A statistically significant higher share of commercial enrollees vs Part D beneficiaries were female (61.0% vs 51.0%; P < .001), and a statistically significantly lower share were using 3 or more branded medications (28.7% vs 42.6%; P < .001). Mean out-of-pocket spending per beneficiary per drug in 2019 was $4478 in Part D (median [IQR], $4169 [$3369-$5947]) compared with $1821 for commercial (median [IQR], $1272 [$703-$1924]); these differences were statistically significant every year. Differences in out-of-pocket spending comparing commercial enrollees aged 60 to 64 years and Part D beneficiaries aged 65 to 69 years exhibited similar magnitudes and trends. By plan, mean out-of-pocket spending per beneficiary per drug in 2019 was $4301 (median [IQR], $4131 [$3000-$6048]) in Medicare Advantage prescription drug (MAPD) plans, $4575 (median [IQR], $4190 [$3305-$5799]) in stand-alone prescription drug plans (PDPs), $1208 (median [IQR], $752 [$317-$1240]) in health maintenance organization plans, $1569 (median [IQR], $838 [$481-$1472]) in preferred provider organization plans, and $4077 (median [IQR], $2882 [$1075-$4226]) in high-deductible health plans. There were no statistically significant differences between MAPD plans and stand-alone PDPs in any study year. Mean out-of-pocket spending was statistically significantly higher in MAPD plans compared with health maintenance organization plans and in stand-alone PDPs compared with preferred provider organization plans in each study year.

Conclusions and Relevance

This cohort study demonstrated that the $2000 out-of-pocket cap included in the Inflation Reduction Act may substantially moderate the potential increase in spending faced by individuals who use ultra-expensive drugs when moving from commercial insurance to Part D coverage.

Me31B/DDX6 is a DEAD‐box family RNA helicase playing roles in post‐transcriptional RNA regulation in different cell types and species. Despite the known motifs/domains of Me31B, the in vivo functions of the motifs remain unclear. Here, we used the Drosophila germline as a model and used CRISPR to mutate the key Me31B motifs/domains: helicase domain, N‐terminal domain, C‐terminal domain and FDF‐binding motif. Then, we performed screening characterization on the mutants and report the effects of the mutations on the Drosophila germline, on processes such as fertility, oogenesis, embryo patterning, germline mRNA regulation and Me31B protein expression. The study indicates that the Me31B motifs contribute different functions to the protein and are needed for proper germline development, providing insights into the in vivo working mechanism of the helicase.

Published: May 2023

Thermomechanical stress simulations are combined with experimental tests to assess the effects of rigid inclusions on the sintering of 8 mol% yttria‐stabilized zirconia (8YSZ) green compacts and the phenomena of restricted and differential sintering on microstructure development and electrical properties are investigated. Rigid inclusions of sintered ceramic particles with different shapes (spherical and jagged) and compositions (alumina, 3YSZ, and 8YSZ) are added in different volume fractions (1, 5, and 15 vol%) to 8YSZ commercial powders, which are formed by isostatic pressing and sintered by conventional method. Restricted and differential sintering effects are observed in the development of the microstructure varying in function of volume fraction, shape, structural composition, and thermomechanical properties of the inclusions, resulting in different combinations of tensile and compressive strain states in the matrix, and varying electrical behaviors. The addition of 1 vol% of 8YSZ irregular rigid inclusions leads to an increase of 36% in total electrical conductivity and a 33% increase in power density under solid oxide fuel cells operation conditions compared to samples without inclusions.

Two‐dimensional (2D) lead halide perovskites (LHPs) have shown great promises for light‐emitting applications and excitonic devices. Fulfilling these promises demands an in‐depth understanding on the relationships between the structural dynamics and exciton‐phonon interactions that govern the optical properties. Here, we unveil the structural dynamics of 2D lead iodide perovskites with different spacer cations. Loose packing of an undersized spacer cation leads to out‐of‐plane octahedral tilting, whereas compact packing of an oversized spacer cation stretches Pb−I bond length, resulting in Pb2+ off‐center displacement driven by stereochemical expression of the Pb2+ 6s2 lone pair electrons. Density functional theory calculations indicate that the Pb2+ cation is off‐center displaced mainly along the direction where the octahedra are stretched the most by the spacer cation. We find dynamic structural distortions associated with either octahedral tilting or Pb2+ off‐centering lead to a broad Raman central peak background and phonon softening, which increase the non‐radiative recombination loss via exciton‐phonon interactions and quench the photoluminescence intensity. The correlations between the structural, phonon, and optical properties are further confirmed by the pressure tuning of the 2D LHPs. Our results demonstrate that minimizing the dynamic structural distortions via a judicious selection of the spacer cations is essential to realize high luminescence properties in 2D LHPs.

Published: May 2023

Using a one‐pot hydrothermal method with ethylenediamine, we have synthesized mesoporous PtPb nanosheets that exhibit exceptional activity in both hydrogen evolution and ethanol oxidation. The resulting PtPb nanosheets have a Pt‐enriched structure with up to 80 % atomic content of Pt. The synthetic method generated a significant mesoporous structure, formed through the dissolution of Pb species. These advanced structures enable the mesoporous PtPb nanosheets to achieve a current density of 10 mA cm−2 with an extreme low overpotential of 21 mV for hydrogen evolution under alkaline conditions. Furthermore, the mesoporous PtPb nanosheets exhibit superior catalytic activity and stability for ethanol oxidation. The highest catalytic current density of PtPb nanosheets is 5.66 times higher than that of commercial Pt/C. This research opens up new possibilities in designing mesoporous, two‐dimensional noble‐metal‐based materials for electrochemical energy conversion with excellent performance.

Published: May 2023

Redox flow batteries have been discussed as scalable and simple stationary energy storage devices. However, currently developed systems encounter less competitive energy density and high costs, restricting their wider application. There is a lack of appropriate redox chemistry, preferably based on active materials that are abundant in nature and show high solubility in aqueous electrolytes. A nitrogen‐centered redox cycle operating between the limiting species ammonia and nitrate via an eight‐electron redox reaction stayed practically unnoticed, albeit its ubiquity in biological processes. Ammonia or nitrate are world‐scale chemicals with high aqueous solubility, and are then comparably safe. We demonstrate here the successful implementation of such a nitrogen‐based redox cycle between ammonia and nitrate with eight‐electron transfer as a catholyte for Zn‐based flow batteries, which continuously worked for 12.9 days with 930 charging‐discharging cycles. A very competitive energy density of 577 Wh L−1 can be reached, which is well above most reported flow batteries (e.g. 8 times the standard Zn‐bromide battery), demonstrating that the nitrogen cycle with eight‐electron transfer can offer promising cathodic redox chemistry for safe, affordable, and scalable high‐energy‐density storage devices.
