Published: October 2023

Knowing the composition of mosquito community, their temporal dynamics and relationship with abiotic factors in urban areas is of interest in public health because many species are vectors of pathogens. This is the first survey of diurnal adult mosquitoes in an urban reserve in Buenos Aires City (Argentina). Fortnightly daytime samples were carried out during a year affected by a drought due to La Niña effect, to describe the adult mosquito community and analyze its association with environmental variables. Ten species belonging to the genera Culex L., Aedes Meigen, Psorophora Robineau-Desvoidy and Mansonia Blanchard were captured, some of which are vectors of pathogens (e.g. Aedes albifasciatus (Macquart) and the complex Culex pipiens L.). Diversity did not vary significantly among seasons, and the composition was moderately similar (ANOVA: p = 0.11; Dice-Sorensen: 0.50-0.77). However, classification of species as core, common or rare in the community varied. A canonical correspondence analysis allowed us to identify a group of five species associated with summer and high temperatures. The other species were not grouped, and were associated with rainfall, relative humidity or another season. These associations help to understand the presence and abundance of those species during a prolonged drought.

Published: October 2023

Goniozus legneri Gordh (Hymenoptera: Bethylidae) is a larval ectoparasitoid of lepidopterans, with a worldwide history as a biocontrol agent of various agricultural pests. By means of extensive monitoring, this wasp was found in four distant districts of Mendoza province parasitizing three lepidopteran pests: Lobesia botrana (Den. et Shiff.) in grapevine, Ectomyelois ceratoniae (Zeller) in walnut and “espinillo” (Vachellia caven (Molina) Seigler et Ebinger) and Cydia pomonella (L.) in walnut. To corroborate the parasitoid species identification and to analyze its population viability in this region, studies of male genitalia and sexual crossings between wild and laboratory-reared wasps were conducted. Further, we report for the first time the natural host-parasitoid interaction of L. botrana with this parasitoid in vineyards from Argentina.

Published: October 2023

The species Aegomorphus quadrigibbus (Say) and Thryallis undatus (Chevrolat) (Coleoptera: Cerambycidae) were identified causing damage to Persian lime trees in Martínez de la Torre municipality orchards, in central Veracruz state, Mexico. Ovipositions made by the adults to lay eggs on trunks and branches were observed, with galleries between two and five cm deep, which caused the branches to dry up and, in some cases, complete death of the trees. In trees previously affected with vascular pathogens or with nutrient deficiencies, the damage was more severe because the larvae formed galleries that surrounded the trunk or branches, preventing the flow of nutrients. The average incidence in the sampled trees was 10.8%. Since the Martínez de la Torre area is the most important Persian lime production region in Mexico, it is necessary to monitor crops to determine the presence of insects and develop studies to define levels of damage and management strategies for their insects’ populations when required. This is the first record of A. quadrigibbus and T. undatus associated with trees of the Rutaceae family and causing damage to Persian lime orchards.

Authors: Arabinda Kumar Sahoo  , Poonam Singh Kharwar
Published: October 2023

Adjustment is an age-old concept that helps in maintaining wellbeing of the individual and the society. Pre-service teacher education prepares students towards making a competent individual that can effectively manage the society, hence the pre-service teachers must be a well-adjusted individual. Language often plays a key role in determining the adjustment pattern of any individual. The present study made an attempt to explore the adjustment problems of pupil-teachers with specific focus on the local and official language related issues. The objectives included identification of language-related adjustment levels of pupil-teachers and the difference of adjustment level on the basis of certain demographic variables like gender, locality, area, and age group. The sample of this descriptive survey study comprised of 165 pupil-teachers of Western Odisha region selected through simple random sampling. The data was collected using a self-standardized tool named LBAS (Language Barrier and Adjustment Scale). The findings revealed that there was a significant level of adjustment issues among the pupil-teachers. However, there were no significant differences amongst the pupil-teachers on the basis of gender, locality, area, and age group.

Methods to synthesize diverse collections of substituted piperidines are valuable due to the prevalence of this heterocycle in pharmaceutical compounds. Here, we present a general strategy to access N-(hetero)arylpiperidines using a pyridine ring-opening, ring-closing approach via Zincke imine intermediates. This process generates pyridinium salts from a wide variety of substituted pyridines and (heteroaryl)anilines; hydrogenation reactions and nucleophilic additions then access the N-(hetero)arylpiperidine derivatives. We successfully applied high-throughput experimentation (HTE) using pharmaceutically relevant pyridines and (heteroaryl)anilines as inputs and developed a one-pot process using anilines as nucleophiles in the pyridinium salt-forming processes. This strategy is viable for generating piperidine libraries and applications such as convergent coupling of complex fragments.

Published: October 2023

Intracellular radicals play important roles in cell signaling and regulation of growth factors, cytokines, transcription, apoptosis, and immunomodulation, among others. To gain a more comprehensive understanding of their biological functions in a spatio-temporal perspective, there is a great need for nanoscale sensitive tools that allow real-timeiin detection of these reactive species. Currently, intracellular radical probes are based on chemical reactions that could significantly alter radical levels during detection. Due to the excellent biocompatibility and favorable photophysical properties of nitrogen-vacancy (NV‒) centers in fluorescent nanodiamonds (fNDs), the fNDs can serve as a powerful and chemically inert nanotool for intracellular radical detection. In this study, a positively charged nanogel (NG) coating was prepared to prevent the precipitation of fNDs and promote cellular internalization. After internalization of nanodiamond-nanogels (fND-NGs), different stimulators, namely somatostatin (SST), triphenylphosphonium (TPP), and trans-activator of transcription (TAT) peptide, which are widely used cell- or organelle- targeting ligands in medicine, drug delivery, and diagnostics, were applied to stimulate the cells. In parallel, the intracellular radical changes under stimulation of SST, TPP, and TAT ligands were monitored by fND-NGs in a home-built ODMR microscope. Our method allows for detecting intracellular radicals in-situ and monitoring their real-time changes during incubation with the targeting ligands in a single living cell. We believe that our method will provide insights into the generation of radical stress in cells, which could improve our fundamental understanding of the pharmacology and signaling pathways of widely used cell- and organelle-targeting ligands associated with free radicals.

Published: October 2023

The stability of CsPbBr3 nanocrystals (NCs) in open air remains challenging and can vary depending on the specific material and conditions. Generally, perovskites are prone to degradation due to oxygen, moisture, polar solvent, and light exposure. In this work, we have aimed to develop strategies to improve the stability of CsPbBr3 perovskite and broaden its potential applications in organic synthesis. An orthorhombic CsPbBr3 perovskite nano-crystal (NC) obtained from bromide precursor dibromoisocyanuric acid, can work efficiently as a visible light photocatalyst (blue LED, 5 mol % and TON ~ 18.11) under O2 atmosphere and in acetonitrile (dielectric constant ε ~ 37.5). The synthesis of diaryl sulfides and a diaryl selenide were achieved via template-free C-H functionalization of electron-rich arenes. The electron-rich arenes also helped to enhance the stability of the CsPbBr3 perovskites photocatalyst within the reaction system. The orthorhombic and bromide-rich CsPbBr3 NC displayed superior photocatalytic activity than cubic CsPbBr3 NCs and was found to be environmentally benign. After the reaction, only 32 ppb of Pb(II) was leached out (ICP-OES analysis) which is quite lower than the maximum permissible limit for drinking water of humans (50 ppb).

Performance Analysis of Islamic Banking in Pakistan Using DEA Technical Efficiency and Maqasid-e-Shariah Index
Authors: Ali Usman , Hussain Khalid , Sheikh Rafiullah
Published: October 2023

Purpose: The goal of Islamic banking is to offer Shariah compliant products along with ultimate objective of high performance. We question whether Islamic banks are able to achieve the Shariah objectives as well as the efficiency. Design/Methodology/Approach: We use Maqasid-e-Shariah index (MSI) to assess the level of Shariah compliant and DEA technical efficiency score to measure the performance of Islamic banks in Pakistan. Results of efficiency and MSI scores are combined and plotted on four quadrants. Since the best bank is set as benchmark, the study provides relative results not absolute. Findings: The study has four main findings based on the results. Meezan Bank falls in quadrant 1 which achieves highest level of technical efficiency and high level of MSI score. Bank Islami and Al-barakah Bank fall in quadrant 2 which depicts that both banks achieve high technical efficiency but low MSI scores. Dubai Islamic Bank falls in quadrant 3 having low score in technical efficiency and high score in MSI. Quadrant 4 has the lowest level in both the technical efficiency and MSI. None of the banks falls in this quadrant. Although, Meezan Bank achieves the highest level of MSI, nevertheless all banks are required to improve the MSI scores. Originality/Significance: Large number of studies uses the DEA approach to measure the efficiency of Islamic banks. On the other hand, another set of research studies prefer MSI approach to determine the efficiency of Islamic banks. To the best of our knowledge, this is perhaps the first study in Pakistan, which uses both approaches to compare the technical efficiency and Maqasid-e-Shariah based efficiency of Islamic banks. Practical and Social Implications: Since all Islamic banks are meant to achieve highest possible level of Maqasid-e-Shariah, the management of these banks has to focus on improving MSI scores along with highest technical efficiency. In this regard, the paper provides insight to management, Shariah advisors and regulators in the performance of Islamic banking from both conventional and Shariah aspects.

Sources of difficulties and selection of strategies in translation of socio-political terms
Authors: Kotlyarov Dmytro
Published: October 2023

The purpose of this study was to identify and analyze the most common difficulties faced by students in translating socio-political terminological units from English and Ukrainian and the strategies they choose to overcome these difficulties. To achieve this goal, two lists of terminological units had been compiled in English and Ukrainian. The total number of units per a testee was one hundred and fifteen words and word combinations in each language. The testees were third and fourth year students of the School of Foreign Languages at V. N. Karazin Kharkiv National University, who had mastered specialized courses in the socio-political field of translation during several semesters, and therefore had gained some experience in translating the relevant terminology. They were asked to translate the above mentioned terms within seventy minutes. Then their translations were analyzed: the types of difficulties that caused errors were identified and systematized. The analysis of erroneous answers showed that most errors were caused by: unjustified word-for-word translation, which was caused by faulty selection of a translation equivalent; interlingual and intralinguistic interference; semantic modification; structural complexity; low frequency of the terminological unit and lack of subject knowledge. The sources of difficulties that students have in translating socio-political terminology, and the strategies they choose to overcome them, are generally the same as in other fields of translation. These sources and strategies should be considered in designing training courses for future translators.
The design of a low-power 4-bit barrel shifter for a current steering DAC using optimized multiplexers in 65 nm technology
Authors: Ashok Kumar Adepu , Balaji Narayanam
Published: October 2023

CMOS technology scaling has paved the way for a faster and more complex integration. Low-power techniques have become crucial because of the demand for low power consumption and high speed. The main objective of this research is to utilize low-power techniques to implement a 4-bit barrel shifter that can shift or rotate data using any number of bits within a single cycle. Gate Diffusion Input (GDI), modified GDI, and full-swing GDI logic have been employed to implement a 2:1 multiplexer, among which the modified GDI-based multiplexer stands out because of its minimal power consumption. Consequently, a 4-bit barrel shifter is implemented using a modified GDI-based multiplier. All designs and simulations were performed using the Cadence Virtuoso tool in UMC 65 nm technology. This technology enables the accurate analysis and assessment of the designed barrel shifter, considering the characteristics and limitations of the 65 nm process. This study focused on leveraging low-power techniques to implement a 4-bit barrel shifter to address the industry's demand for power-efficient solutions. The modified GDI-based multiplexer is a promising choice that provides a balance between low power consumption and high performance. The use of advanced design tools and selected technology further ensures accurate simulations and evaluations of the proposed design.
