Quality of Education among Primary School Children receiving Mid-Day Meal: Evidence from a Quasi-Experiment

This paper on the basis of Quasi-experiment shows that ‘quality of education’ of the students of the government owned primary schools getting mid-day meal are not satisfactory. Lack of giving sufficient importance on education by the parents for their children mainly coming from low socio-economic back ground is the major cause behind that

EGF Signal Propagation during C. elegans Vulval Development Mediated by ROM-1 Rhomboid

During Caenorhabditis elegans vulval development, the anchor cell (AC) in the somatic gonad secretes an epidermal growth factor (EGF) to activate the EGF receptor (EGFR) signaling pathway in the adjacent vulval precursor cells (VPCs). The inductive AC signal specifies the vulval fates of the three proximal VPCs P5.p, P6.p, and P7.p. The C. elegans Rhomboid homolog ROM-1 increases the range of EGF, allowing the inductive signal to reach the distal VPCs P3.p, P4.p and P8.p, which are further away from the AC. Surprisingly, ROM-1 functions in the signal-receiving VPCs rather than the signal-sending AC. This observation led to the discovery of an AC–independent activity of EGF in the VPCs that promotes vulval cell fate specification and depends on ROM-1. Of the two previously reported EGF splice variants, the longer one requires ROM-1 for its activity, while the shorter form acts independently of ROM-1. We present a model in which ROM-1 relays the inductive AC signal from the proximal to the distal VPCs by allowing the secretion of the LIN-3L splice variant. These results indicate that, in spite of their structural diversity, Rhomboid proteins play a conserved role in activating EGFR signaling in C. elegans, Drosophila, and possibly also in mammals

Rapid MPN-Qpcr Screening for Pathogens in Air, Soil, Water, and Agricultural Produce

A sensitive, high-throughput, and cost-effective method for screening bacterial pathogens in the environment was developed. A variety of environmental samples, including aerosols, soil of various types (sand, sand/clay mix, and clay), wastewater, and vegetable surface (modeled by tomato), were concomitantly spiked with Salmonella enterica and/or Pseudomonas aeruginosa to determine recovery rates and limits of detection. The various matrices were first enriched with a general pre-enrichment broth in a dilution series and then enumerated by most probable number (MPN) estimation using quantitative PCR for rapid screening of amplicon presence. Soil and aerosols were then tested in non-spiked environmental samples, as these matrices are prone to large experimental variation. Limit of detection in the various soil types was 1–3 colony-forming units (CFU) g[superscript −1]; on vegetable surface, 5 CFU per tomato; in treated wastewater, 5 CFU L[superscript −1]; and in aerosols, >300 CFU mL[superscript −1]. Our method accurately identified S. enterica in non-spiked environmental soil samples within a day, while traditional methods took 4 to 5 days and required sorting through biochemically and morphologically similar species. Likewise, our method successfully identified P. aeruginosa in non-spiked aerosols generated by a domestic wastewater treatment system. The obtained results suggest that the developed method presents a broad approach for the rapid, efficient, and reliable detection of relatively low densities of pathogenic organisms in challenging environmental samples.United States-Israel Binational Agricultural Research and Development Fund (Grant No. CP-9033-09)MIT International Science and Technology InitiativesKraft Foods Compan

The dilemma of COVID-19 vaccination among Health Care Workers (HCWs) of Uttar Pradesh

Background: Immediately after the outbreak of COVID-19 pandemic, with an unprecedented cooperation between biomedical, pharmaceutical, technological, and political sectors, new vaccines were developed and approved in record times. However, doubts were raised on their efficacy and adverse effects. Globally, it was agreed that the first recipients for vaccines would be the health care workers (HCWs). Logically, it was bound to raise some concerns and result in hesitancy among the HCWs. Aims: The current study was planned to study the proportion of HCWs having hesitancy towards COVID-19 vaccination and factors effecting it. Settings and Design: Cross-sectional study conducted among HCWs of Uttar Pradesh. Methods and Material: The survey was conducted both in online and offline mode and attempted by 254 HCWs eligible for receiving COVID-19 vaccine. Statistical analysis used: t-test, chi-square test, proportion, mean, SD Results: Vaccine hesitancy was present in 35.8% HCWs. Only social factors like caste (p=0.023) and religion (p<0.001) were found to be significantly associated with vaccine hesitancy. Gender, type of health worker, fear of COVID-19 infection, fear of lethality or pre-existing diseases did not affect vaccine hesitancy. The maximum number of HCWs (71.4%) were hesitant because they were unsure of the side-effects followed by the reason of being unsure about its effect on their own health (53.8%). When asked about their attitude towards compulsory COVID-19 vaccination for HCWs, should it be made mandatory by the government, 42.9% were in favour and 40.6% were against any such mandate. Conclusions: The study concluded that social factors like religion and caste are more deterministic for vaccine hesitancy

Floristic diversity of Theog Forest Division, Himachal Pradesh, Western Himalaya

We provide a check list of the vascular plants of Theog Forest Division, Himachal Pradesh, Western Himalaya. Himachal Pradesh has been extensively surveyed in terms of flora by a large number of workers, albeit highly confined to prioritized areas. The floristic inventorization resulted in a total of 442 vascular plant species belonging to 311 genera and 117 families from an area of 512 km2. Out of these, 408 species belonged to Angiosperms, 7 to Gymnosperms and 27 to Pteridophytes. The predominant families among Dicotyledons were Asteraceae, Rosaceae and Lamiaceae. Among the Monocotyledons, the most represented family was Poaceae, followed by Liliaceae and Cyperaceae. Pinaceae and Pteridaceae were found to be the most represented families among the Gymnosperms and Pteridophytes, respectively. Species richness was highest in shrubberies, which formed an ideal habitat for many herbaceous species within different habitat types. Strategic eradication of weed species, especially obnoxious species such as Lantana camara and Parthenium hysterophorus is required for effective management in the area

Prevalence of dementia and its associated risk factors among elderly patient attending Outpatient Department of a tertiary care hospital in Lucknow

Background: Dementia is a broad category of brain diseases that causes a chronic, progressive and gradual decrease in cognitive function i.e. ability to think and remember that is great enough to affect a person’s daily functioning beyond what might be expected from normal ageing. According to American Psychiatric Association, “Dementia is a syndrome caused by a variety of brain illnesses that affect memory, thinking, behaviour and the ability to perform everyday activities”. Aim & Objectives: To assess the prevalence of dementia among the patients above 60 years of age attending the outpatient department of Tertiary care super specialty hospital. To assess the risk factors associated with occurrence of dementia in patients attending outpatient department of Tertiary care super specialty hospital. Settings and Design: Study design: - Cross-sectional observational study. Study area: - Tertiary care super-specialty hospital. Study setting: - Outpatient department (OPD)of Tertiary care super specialty hospital.

In our study which included the patients above 60 years of age out of which the maximum participants (52.4%) were of age group 65-75. In our study 66.2% participants had normal cognitive functioning while 33.8% of total participants were found to have dementia. Out of these 33.8% participants having impaired cognitive functioning, 13.8% and 20% had severe and borderline dementia respectively. Dementia was found to be more common in females. Conclusions: Statistically significant association of dementia has been found with female gender, rural residence, joint family and a greater number of family members, poor education, pan masala consumption, daytime drowsiness, and problem in sleep pattern, social intolerance and frequent fights

Disparity in Relation to Covid-19 Preventive Behaviour and Associated Myths among Rural and Urban Residents of Lucknow: A Community Based Study

Introduction: For curbing Covid-19 disease, adequate knowledge, attitude, and practices of both rural and urban population for Covid-19 disease prevention is required along with busting of the associated myths. Objectives: To assess the Knowledge, Attitude and Practices of urban and rural residents of Lucknow district regarding covid-19 preventive behaviour and associated myths. Methodology: A community-based study was conducted among 420 rural and 421 urban residents of Lucknow. Multistage random sampling was done to select the study subjects. A pre-designed pretested semi-structured questionnaire was used to collect the information regarding the Knowledge, Attitude and Practices of the residents for covid-19 disease causes, prevention, and treatment. Further, KAP scoring was done to compare the two groups. Results: The mean age of the rural and urban residents was 31.48 ± 12.05 and 30.93 ± 11.96 years respectively. Only 40.4 % urban and 25.5 % rural people had correct knowledge about social distancing (p<0.0001). Knowledge regarding quarantine for covid-19 disease prevention was less among the urban residents (64.6%) as compared to rural (70.5%) (p=0.035). More than one-third (37.6%) of the rural resident believed in the myth that alcohol can prevent the covid-19 disease (p=0.003). 68.8 and 70.5 percent rural and urban residents had positive attitude towards the Indian government’ efforts in curbing the disease. Majority of the urban (90%) and rural (87.6%) residents wore mask when they went out. Only one-fourth of the urban (24.7%) and rural (22.9%) had correct practices for the duration of hand washing. Conclusion: The knowledge was more among the urban people, attitude and practices were almost similar among both the rural and urban residents while myths were more observed among the rural residents

IC age estimation methodology using IO pad protection diodes for prevention of Recycled ICs

Recycled ICs have become a major threat to the ICs used in safety critical systems. In the current state-of-the-art techniques, recycled ICs are detected by measuring the frequency, current, path delay or power-up values to estimate the HCI, BTI and EM effects on the transistors with age. Some of the state-of-the-art techniques require additional on-chip sensors to detect and estimate the age of an IC while others use existing logic like SRAM and Flip-flops to detect the recycled ICs. In this paper, we provide a methodology to detect a recycled IC and also to estimate its age by using the existing IO pad structures. For the first time, age is estimated by measuring voltage drop across the protection diodes present in IO pad structure. With this methodology, no additional sensors have to be added and hence there is no area overhead. With this proposed methodology, ICs that are used for a minimum period of a day can be effectively detected by using the concept of extended Kalman filtering technique for the first time in this domain. By stressing the part for five days, our proposed methodology can estimate the age of the IC aged between 1 month to 5 years with 95% percent of accuracy. © 2021 IEE

Static properties of nuclear matter within the Boson Loop Expansion

The use of the Boson Loop Expansion is proposed for investigating the static properties of nuclear matter. We explicitly consider a schematic dynamical model in which nucleons interact with the scalar-isoscalar sigma meson. The suggested approximation scheme is examined in detail at the mean field level and at the one- and two-loop orders. The relevant formulas are provided to derive the binding energy per nucleon, the pressure and the compressibility of nuclear matter. Numerical results of the binding energy at the one-loop order are presented for Walecka's sigma-omega model in order to discuss the degree of convergence of the Boson Loop Expansion.Comment: 40 pages, 13 figure
