Gas rich galaxies from the FIGGS survey
The FIGGS (Faint Irregular Galaxy GMRT Survey) is aimed at creating a
multi-wavelength observational data base for a volume limited sample of the
faintest gas rich galaxies. In this paper we discuss two very gas rich galaxies
that were observed as part of the FIGGS survey, viz. NGC 3741 and And IV. These
galaxies are unusual in that they have extremely extended gas disks and very
high ratios of dark to luminous matter. The very extended HI disks provide an
unique opportunity to trace the extended distribution of dark matter around
faint galaxies. We compare the baryon fraction of these galaxies with a sample
of galaxies with well measured rotation curves and discuss whether extremely
gas rich dwarf galaxies have abnormally small baryon fractions.Comment: 5 Pages, 4 Figures. To be published in the proceedings of "Galaxies

Impact of Job Insecurity on Work–Life Balance during COVID-19 in India
The ongoing health crisis has impacted businesses worldwide, drastically reducing production, consumption and distribution of goods and services, leading to an economic downturn. An increasing unemployment rate has led to a surge in the sense of job insecurity among employees. Lack of job security has a direct impact on an employee’s health and work–life balance. This article focusses on the relationship between and impact of job insecurity on work–life balance, that is, to understand the impact of perceived job insecurity on working hours, employee’s health and reduced family time. Using a self-completed questionnaire, data was collected from 413 employees from different sectors like construction, banks, hospitals, hotels, schools, FMCG, telecommunication, etc., in India, which assisted in testing five hypotheses. The study found a positive relationship between job insecurity and health issues and work–life conflict. Additionally, job insecurity was negatively linked with job performance. Regression analysis showed mediating effects of work demand, work time, family time and family demand on the relationship of job insecurity with health issues, job performance and work–life conflict. However, the article also discusses various effective mechanisms to reduce job insecurity and ways to curb its negative impacts on various organizational and personal outcomes
Business Model for Non-Conventional Energy Source: Absorption Refrigeration System Using Solar Evacuated Tube Collectors
The clean source of energy such as solar power has great potential which has not been tapped yet, in a country where heat is highly affecting the environment the electrical load due to the functioning of air conditioning is quite high, the cooling load can be reduce by single effect vapor absorption which has a huge potential and very promising in summer months in the tropical countries. The use of evacuated tubes with Lithium Bromide-Water as a refrigerant is a very collaboration in our current stud and by reducing the CO2 emissions to study for 5.25 KW system

The Nearby and Extremely Metal-Poor Galaxy CGCG 269-049
We present Hubble Space Telescope (HST) and Spitzer Space Telescope images
and photometry of the extremely metal-poor (Z = 0.03 Z_sol) blue dwarf galaxy
CGCG 269-049. The HST images reveal a large population of red giant and
asymptotic giant branch stars, ruling out the possibility that the galaxy has
recently formed. From the magnitude of the tip of the red giant branch, we
measure a distance to CGCG 269-049 of only 4.9 +/- 0.4 Mpc. The spectral energy
distribution of the galaxy between ~3.6 - 70 microns is also best fitted by
emission from predominantly ~10 Gyr old stars, with a component of thermal dust
emission having a temperature of 52 +/- 10 K. The HST and Spitzer photometry
indicate that more than 60% of CGCG 269-049's stellar mass consists of stars
~10 Gyr old, similar to other local blue dwarf galaxies. Our HST H-alpha image
shows no evidence of a supernova-driven outflow that could be removing metals
from the galaxy, nor do we find evidence that such outflows occurred in the
past. Taken together with CGCG 269-049's large ratio of neutral hydrogen mass
to stellar mass (~10), these results are consistent with recent simulations in
which the metal deficiency of local dwarf galaxies results mainly from
inefficient star formation, rather than youth or the escape of supernova
ejecta.Comment: 35 Pages, 7 Figures, accepted for publication in ApJ; new version

Development of two high yielding mutant varieties of mustard [Brassica juncea (L.) Czern.] through gamma rays irradiation
Seeds of the well-adapted and popular mustard variety BARIsarisha-11 were irradiated with gamma ray using 60Co gamma cells. Irradiated seeds were grown as M1 during 2004-05. Selection was made from M2 generation during 2005-06. Desirable mutants were confirmed in M4 generation during 2007-08 and ten true breeding mutants having higher seed yield per plant with desirable morphological characters and yield attributes were selected. Selected mutants were evaluated along with the mother variety BARIsarisha-11 to select the most desirable ones considering higher seed yield and improved yield attributes under different replicated yield trials during 2008-09 to 2010-11. Results showed that two mutants, MM-10-04 and MM-08-04 selected from 700 Gy produced higher seed yield than BARIsarisha-11 in most of the trials conducted in 13 locations of Bangladesh. Mean of three years trial showed that seed yield of MM-10-04 and MM-08-04 was 2043 and 1893 kg ha-1, respectively, which was 23% and 14% higher than BARIsarisha-11 (parental plant). Mutants MM-10-04 and MM-08-04 also had the higher number of siliquae plant-1, 1000-seed weight and oil content than BARIsarisha-11. These two mutants also showed tolerance against Alternaria blight disease and lower aphid infestation. Results of the yield trials as well as screening against Alternaria blight disease and aphid carried out across the country indicated that MM-10-04 and MM-08-04 were suitable for widespread cultivation. Consequently, the National Seed Board of Bangladesh registered MM-10-04 and MM-08-04 in 2011 as two high yielding mustard varieties, Binasarisha-7 and Binasarisha-8, respectively for commercial cultivation
Business of Fashion, Textiles & Technology: Summary Report: Mapping the UK Fashion, Textiles and Technology Ecosystem
The UK fashion, apparel and textiles industry is a globally competitive growth sector. The 2015 Value of Fashion report by Oxford Economics, commissioned by the British Fashion Council, found that the direct economic value of a flourishing sector including retail, manufacturing and textiles was £28.1 billion – and calculated its indirect impact at a further £22.6 billion, making a total contribution to gross domestic product of over £50 billion[3]. However, it is less well understood than other creative industries. The final product is generally perceived as catwalk-related in some way. In order to shift that perception, the Business of Fashion, Textiles and Technology (BFTT) report considers the fashion, textiles and technology industry as a wide range of intersecting sectors, spanning – quite literally – from agriculture to advertising.
To date, the industry has been constrained by lack of innovation in business strategy and the late adoption of technology. These structural factors have severely limited investment in research, development and knowledge exchange within the broader Fashion, Textiles and Technology (FTT) ecosystem. Currently, the industry lacks robust data and compelling evidence compared to other creative industries regarding research and development (R&D) opportunities, business growth options, job creation and investment. Official data sources on the fashion industry are limited to ‘designer fashion’, which is conflated with ‘other design’ activity, and focuses on established brands and large retailers, and unrelated textiles manufacturers. In response to this deficit and to concerns around R&D, identified through the development of the BFTT creative R&D partnership proposal (2017), the BFTT’s first task was to launch a UK-wide survey of the FTT ecosystem (2019).
Approximately one year later, the survey consultation (the launch of which preceded Covid-19 and Britain’s exit from the EU) had engaged over 2,400 small, medium and micro businesses (SMEs) and over 100 stakeholders and intermediaries, including industry specialists, trade bodies and workspace providers. The consultation received 814 survey responses and led to 65 stakeholder interviews, making it one of the most extensive baseline studies to date on FTT SMEs.
BFTT surveyed and interviewed across the entire UK fashion and wider apparel value chain. Therefore, this report for the first time positions the UK sector as not weighted toward fashion only. It illustrates the textile, materials and technology elements as key parts of this ecosystem and shows the industry is highly heterogeneous, made up of intersecting textiles and technology companies that inform an array of multiple sectors
How Has Intervention Fidelity Been Assessed in Smoking Cessation Interventions? A Systematic Review
Introduction. Intervention fidelity concerns the degree to which interventions are implemented as intended. Fidelity frameworks propose fidelity is a multidimensional concept relevant at intervention designer, provider, and recipient levels; yet the extent to which it is assessed multidimensionally is unclear. Smoking cessation interventions are complex, including multiple components, often delivered over multiple sessions and/or at scale in clinical practice; this increases susceptibility variation in the fidelity with which they are delivered. This review examined the extent to which five dimensions from the Behaviour Change Consortium fidelity framework (design, training, delivery, receipt, and enactment) were assessed in fidelity assessments of smoking cessation interventions (randomised control trials (RCTs)). Methods. Five electronic databases were searched using terms "smoking cessation,""interventions,""fidelity,"and "randomised control trials."Eligible studies included RCTs of smoking cessation behavioural interventions, published post 2006 after publication of the framework, reporting assessment of fidelity. The data extraction form was structured around the framework, which specifies a number of items regarding assessment and reporting of each dimension. Data extraction included study characteristics, dimensions assessed, data collection, and analysis strategies. A score per dimension was calculated, indicating its presence. Results. 55 studies were reviewed. There was a wide variability in data collection approaches used to assess fidelity. Fidelity of delivery was the most commonly assessed and linked to the intervention outcomes (73% of the studies). Fidelity of enactment scored the highest according to the framework (average of 92.7%), and fidelity of training scored the lowest (average of 37.1%). Only a quarter of studies linked fidelity data to outcomes (27%). Conclusion. There is wide variability in methodological and analytical approaches that precludes comparison and synthesis. In order to realise the potential of fidelity investigations to increase scientific confidence in the interpretation of observed trial outcomes, studies should include analyses of the association between fidelity data and outcomes. Findings have highlighted recommendations for improving fidelity evaluations and reporting practices
Effectiveness of commercial versus homemade sports drinks on fluid balance and exercise capacity during high-intensity intermittent exercise
Commercial sports drinks are used widely by athletes involved in high-intensity intermittent (HII) exercise. However, little has been reported on their relative effectiveness compared to simple homemade drink formulations. The purpose of this study was to investigate the effects of different sports drink formulations (commercial v homemade), water and no drink on fluid balance and exercise capacity during HII exercise. Twelve trained men (age: 27 ± 2.1 y) performed a 90-min HII running protocol designed to simulate activity experienced during a football match. The protocol was arranged in six 15-min stages where running speeds ranged between 55% and 120% of VO2max. The HII protocol included half-time and a run to fatigue post 90 min. Using a single-blind, randomized, cross-over design, participants ingested a preload of 5 mlkg-1 10 min before HII exercise and 3 mlkg-1 every 15 min of either Isostar® (ISO), a homemade sports drink (CHO), placebo (P) or no drink (ND). Blood lactate (Hla), blood glucose (Bgluc), heart rate (HR) and ratings of perceived exertion (RPE) were measured before, during (every 15 min) and after the 90-min HII protocol. Changes in plasma volume were measured at half-time and post 90 min. Sweat rate and fluid balance were calculated post each trial. Time to fatigue (TTF) was recorded at exhaustion. In the ND trial, TTF decreased by approximately 17%, 28% and 43% compared to P, CHO and ISO, respectively (p0.05). No differences were noted in HLa, RPE, PV or SR between the trials (p>0.05) but there were significant effects of time (p<0.05). Bgluc peaked at 30 minutes in ISO and CHO, but dropped by ~27% in ISO and by ~30% in CHO after half time. Absence of fluid ingestion surprisingly had no significant effect on altering plasma volume or decreasing sweat rate despite causing noticeable decreases in exercise capacity. The homemade drink improved exercise capacity in a similar manner to that of the commercial drink, but neither sports drink achieved superior hydration compared to water. Ingestion of exogenous carbohydrate through sports drink consumption caused an exercise-induced glycemic response when exercise was restarted after half-time. This decline in blood glucose after half-time appears to be marginally attenuated in P trial. A possible suggestion for team sports could be to drink water rather than sports drink prior to half-time period
