Aims: The present study was conducted to know the challenges faced by the small scale backyard chicken farmers of Dhemaji district of Assam.
Study Design: The data obtained on various challenges faced by the farmers under the study were tabulated and analyzed statistically by using Garrett’s Ranking Technique.
Place and Duration of Study: The study was conducted at Krishi Vigyan Kendra, Dhemaji, Assam Agricultural University, Simen Chapori, Dhemaji, Assam during the year, 2020-21.
Methodology: For the purpose, a questionnaire was prepared for surveying and data were collected about various challenges in backyard chicken rearing faced by the farmers of the district. The farmers were asked to identify the challenges he or she and the fellow farmers of their villages faced with respect to rearing of local chickens in their locality and to rank the challenges from 1 to 20 according to the seriousness of the challenges faced by them.
Results: Lack of suitable germplasm was found to be the major challenge of poultry farmers with mean score of 74.89 and ranked first among the constraints in backyard chicken rearing. Higher incidence of diseases (68.95), unavailability of feed and feed ingredients (66.55) and mortality of young chicks (63.00) were ranked second, third and fourth major challenges, respectively. On the other hand, non availability of vaccine, higher cost of feeds and feed ingredients, lack of extension training or service, high cost of farm equipments were ranked fifth, sixth, seventh and eighth, respectively, as challenges in backyard chicken rearing. Lack of organized marketing facilities, lack of knowledge on scientific poultry farming, high cost of chicks, presence of middle man, higher mortality during brooding period, inability to diagnose sick birds, inadequate veterinary facilities, seasonal price fluctuations, high cost of medicaments, lack of credit facilities, social problems like damaging of the standing crops by the birds and complaint by neighbours, loss of birds due to predators or thieves were some other constraints of lower importance as indicated by the respondents for the backyard chicken farmers surveyed during the study.
Conclusion: From the study, it can be concluded that the small scale backyard poultry farmers of Dhemaji district of Assam have a lot many challenges in chicken rearing in village conditions, the major being the lack of suitable germplasm and higher incidence of diseases. To address such problems there should be proper initiatives from government level as well as in farmers’ collaborative approach to introduce some newly developed improved chicken breeds and awareness about proper disease prevention and bio-security measures and creation of other facilities.

Background: Serological testing of SARS-CoV-2-specific IgG/IgM antibodies is an important complement to Real Time-PCR (RT-PCR) for surveillance and outbreak investigations. The study therefore aimed to assess the serological survey of SARS-COV-2 among frontline health workers using specific IgG/IgM antibodies.
Methods: The study was a cross-sectional design. A self-administered questionnaire was used to obtain biodata. Rapid diagnostic test kits were used for the study in which samples reacted with COVID-19 antigen-coated particles in the test cassette and the complex formed produced readable bands indicating the presence of SARS-COV19 in the tested subject. Data obtained were analyzed using Stata v15.
Results: The prevalence of SARS-CoV-2 among the study sample was 39.0% and 14.9% for IgG and IgM respectively. Prevalence was highest in the outpatient department (IgG; 70.0%, IgM; 17.1%). IgG positivity was observed more among doctors while positivity for IgG was seen in 78.6% of persons with previous diagnoses. IgM was significantly associated with contact with patients having shortness of breath, p-value < 0.05.
Conclusion: This study demonstrated a high level of SARS-COV19 IgG indicating past infection and IgM suggesting recent exposure or ongoing infection among this group of workers compared to others within the hospital settings. The role of serological testing cannot be over-emphasized in the periodic screening and prompt treatment of health workers before they manifest symptoms or become capable of spreading the disease to innocent patients and or co-health workers.

Published: December 2023

This study aims to analyze students' perception and usage of translation software for language learning. A survey questionnaire was administered to International Engineering College students to gather data on their attitudes, reasons, and experiences related to using translation software. The findings reveal that a significant number of students agree to strongly agree with the use of translation software in various language learning contexts, such as translating simple sentences, long paragraphs, unfamiliar words, and during English classes. The majority of students perceive translation software as a valuable tool for improving language skills and facilitating communication with foreign teachers. However, some students also express dissenting opinions, suggesting that translation software may not be the optimal method for learning and improving English proficiency. The discussion highlights the benefits and limitations of translation software, as well as the need for a balanced approach to its usage. While translation software can be a helpful resource in specific language learning tasks, it should not replace authentic language input and independent learning. The findings emphasize the importance of integrating translation software into language learning curricula and providing guidance to students on effective and critical use. This study contributes to the understanding of students' perceptions of translation software and provides insights for educators and learners on maximizing its potential for language learning.

Published: December 2023

The aim of this study was to assess heavy metal soil pollution in market garden areas in the commune of Korsimoro. The analysis focused mainly on zinc (Zn), nickel (Ni), chromium (Cr), copper (Cu), lead (Pb), cadmium (Cd), cobalt (Co), arsenic (As) and mercury (Hg). Composite samples of soil labels s1 to s21 were taken from the market garden site around the dam at a depth of 0-20 cm. A total of 21 soil samples were taken. The soil samples were analysed using inductively coupled plasma mass spectrometry (ICP/MS) at the Bureau of Mines and Geology of Burkina Faso laboratory (BUMIGEB).
The enrichment factor (EF), contamination factor (CF), géoaccumulation index (Igeo) and pollution load index (PLI) were determined from the metal concentrations obtained.
The average concentrations of heavy metals vary as follows:
Cd > Co > Cr > Zn > Ni > Cu > Hg > Pb > As.
The average concentrations of cadmium (587.039mg/kg±20.546), mercury (29.048mg/kg±20,647), nickel (60.037 mg/kg±14,615) and cobalt (575.956mg/kg±66,693) exceed the WHO limit values for agricultural soils.
The calculated CF values show very high contamination of Co, Cd and Hg, considerable contamination of Cu, Cr, Zn, Ni and As, and no contamination of Pb.
The EF values show very severe enrichment for cobalt (Co), followed by overall extremely severe enrichment for cadmium (Cd) and mercury (Hg).
The calculated Igeo indicates extreme cadmium, mercury and cobalt contamination.
The calculated PLI values are all greater than one. These results show that all the soils are polluted.
The index determination approach makes it possible to predict the extent of soil pollution by the heavy metals considered in our study.

ImportanceHigh myopia (HM) is one of the leading causes of visual impairment worldwide. Genetic factors are known to play an important role in the development of HM.ObjectiveTo identify risk variants in a large HM cohort and to examine the implications of genetic testing of schoolchildren with HM.Design, Setting, and ParticipantsThis cohort study retrospectively reviewed whole-exome sequencing (WES) results in 6215 schoolchildren with HM who underwent genetic testing between September 2019 and July 2020 in Wenzhou City, China. HM is defined as a spherical equivalent refraction (SER) of −6.00 diopters (D) or less. The study setting was a genetic testing laboratory and a multicenter school census. Data were analyzed from July 2021 to June 2022.Main Outcomes and MeasuresThe frequency and distribution of positive germline variants, the percentage of individuals with HM in both eyes, and subsequent variant yield for common high myopia (CHM; −8.00 D ≤ SER ≤ −6.00 D), ultra myopia (UM; −10.00 D ≤ SER &amp;lt; −8.00 D), and extreme myopia (EM; SER &amp;lt; −10.00 D).ResultsOf the 6215 schoolchildren with HM, 3278 (52.74%) were male. Their mean (SD) age was 14.87 (2.02) years, including 355 students in primary school, 1970 in junior high school, and 3890 in senior high school. The mean (SD) SER was −7.51 (−1.36) D for the right eye and −7.46 (−1.34) D for the left eye. Among schoolchildren with HM, genetic testing yielded 271 potential pathogenic variants in 75 HM candidate genes in 964 diagnoses (15.52%). A total of 36 known variants were found in 490 HM participants (7.88%) and 235 protein-truncating variants (PTVs) in 506 participants (8.14%). Involved variant yield was significantly positively associated with SER (Cochran-Armitage test for trend Z = 2.5492; P = .01), which ranged from 7.66% in the CHM group, 8.70% in the UM group, to 11.90% in the EM group. We also found that primary school students with EM had the highest variant yield of PTVs (8 of 35 students [22.86%]), which was 1.77 and 4.78 times that of the UM and CHM, respectively.Conclusions and RelevanceIn this cohort study of WES for HM, several potential pathogenic variants were identified in a substantial number of schoolchildren with HM. The high variation frequency in younger students with EM can provide clues for genetic screening and clinical examinations of HM to promote long-term follow-up assessment.

AbstractRapid progresses concerning wearable electronics call for stretchable batteries. Owing to the merits of high energy density and wide operating voltage range, organic electrolyte‐based lithium‐ion batteries (LIBs) take a large proportion in the powering markets. Due to the high sensitivity to moisture and oxygen, it is difficult to obtain long‐term reliable stretchable organic electrolyte‐based LIBs when they are directly exposed to the air. Benefiting from the outstanding gas impermeability of liquid metal (LM) and relatively good barrier properties for reactive acid gas molecules by polyisobutylene (PIB), an LM‐PIB seal is demonstrated for organic electrolyte‐based LIBs. In the seal, LM can prevent the inward permeation of oxygen and water vapor, and PIB can block the outward permeation of hydrolysis acid generated from the side reactions during the operation of the organic electrolyte‐based LIBs, which helps prevent the detrimental interaction between the hydrolysis acid and LM. A specific capacity of over 120 mAh g−1 is achieved and the battery shows consistent electrochemical performances under multiple deformations. This study offers a different design approach for long‐term operation of stretchable organic electrolyte‐based LIBs.
Multiple Tuning of the Local Environment Enables Selective CO2 Electroreduction to Ethylene in Neutral Electrolytes

Published: December 2023

AbstractRecently, vigorous progress is made in the selective and high‐current reduction of carbon dioxide (CO2) to ethylene (C2H4) by using a flow cell. In most cases, however, the reduction is only achieved in strong alkaline electrolytes, which results in substantial deactivation of electrocatalysts due to the accumulation of precipitates. Here, porous Cu nanowires (NWs) is prepared with abundant atomic defects, which create a synergy with the pore‐induced electric field to comprehensively tune the local microenvironment of the electrode surface, thus enabling efficient and stable C2H4 production from the CO2 reduction reaction (CO2RR) in neutral media. In particular, the enhanced electric field effect increases the local K+ concentration for the generation of *CO intermediates; while the atomic defects stabilize OH− and *CO, leading to high local pH and *CO coverage. Such synergy can provide a favorable local environment and high *CO coverage for significantly decreasing the energy barrier of the C─C coupling step. Consequently, a large partial C2H4 current density of 222.3 mA cm−2 with excellent stability is achieved in a neutral electrolyte. Altogether, this work paves new pathways to promote C2H4 production in the neutral CO2RR through multiple tuning of the local environment.

Published: December 2023

AbstractThe tribovoltaic effect is regarded as a newly discovered semiconductor effect for mechanical‐to‐electrical energy conversion. However, tribovoltaic nanogenerators (TVNGs) are widely limited by low output power and poor wear resistance for device integration and application. Here, this work invents a TVNG using a ball‐on‐disk structure composed of gallium nitride (GaN) and steel ball. It exhibits an open‐circuit voltage exceeding 130 V and an ultrahigh normalized average power density of 24.6 kW m−2 Hz−1, which is a 282‐fold improvement compared to previous works. Meanwhile, this TVNG reaches an ultralow wear rate of 5 × 10−7 mm3 N−1 m−1 at a maximum contact pressure of 906.6 MPa, surpassing the TVNG composed of Si by three orders of magnitude due to the local concentrated injection of frictional energy. Based on the TVNG, this work constructs the first tribovoltaic bearing and achieves sensing signal transmission within 16 s (300 rpm) by integrating a management circuit, a transmission module, a relay, and receiving terminals, which enables the monitoring of ambient pressure and temperature. This work realizes a GaN‐based TVNG with high‐performance and low wear simultaneously, demonstrating great potential for intelligent components and self‐powered sensor nodes in the industrial Internet of Things.

Published: December 2023

AbstractSodium aescinate (SA) shows great potential for treating lymphedema since it can regulate the expression of cytokines in M1 macrophages, however, it is commonly administered intravenously in clinical practice and often accompanied by severe toxic side effects and short metabolic cycles. Herein, SA‐loaded chiral supramolecular hydrogels are prepared to prove the curative effects of SA on lymphedema and enhance its safety and transdermal transmission efficiency. In vitro studies demonstrate that SA‐ loaded chiral supramolecular hydrogels can modulate local immune responses by inhibiting M1 macrophage polarization. Typically, these chiral hydrogels can significantly increase the permeability of SA with good biocompatibility due to the high enantioselectivity between chiral gelators and stratum corneum and L‐type hydrogels are found to have preferable drug penetration over D‐type hydrogels. In vivo studies show that topical delivery of SA via chiral hydrogels results in dramatic therapeutic effects on lymphedema. Specifically, it can downregulate the level of inflammatory cytokines, reduce the development of fibrosis, and promote the regeneration of lymphatic vessels. This study initiates the use of SA for lymphedema treatment and for the creation of an effective chiral biological platform for improved topical administration.
