Sida acuta
is the botanical name of the plant belonging to Malvaceae family.
Sida acuta
fibres are available in nature, relatively low cost and abundantly available in India. The present work has ...been carried out to make use of
Sida acuta
fibres in the fibre reinforced polymer composites. In this study the composites are made using untreated bidirectional
Sida acuta
stem fibre as reinforcement and commercially available epoxy resin as matrix material using hand lay-up technique. The composites are made of different fibre fabric orientation (0°/90° and ± 45°) and each fabric orientation composite with different fibre loading (0, 24, 28 and 32 wt%) are characterized for their physical and mechanical properties. The test results show the significant effect of fibre loading on the physical and mechanical properties of these composites. Also the fracture behaviour and fibre pull-out at the fracture of the composite samples have been analysed using scanning electron microscope.
Molecular variation within known genes controlling specific functions provide candidate gene-based markers which are tightly linked with the trait of interest. Unigene-derived microsatellite markers, ...with their unique identity and positions, offer the advantage of unraveling variation in the expressed component of the genome. We characterized ≥12-bp-long microsatellite loci from 13,899 unique sequences of sorghum
Sorghum bicolor
(L.) Moench available in the NCBI unigene database for their abundance and possible use in sorghum breeding. Analysis of 12,464 unigenes (≥200-bp) using MISA software identified 14,082 simple sequence repeats (SSRs) in 7,370 unigenes, from which 1,519 unigene SSR markers were developed. The average frequency of SSR was 1 per1.6 kb and 1.0 per 1.1 unigene; hexamers followed by trimers were found in abundance, of which 33.3% AT-rich and CCG repeats were the most abundant. Of the 302 unigene SSRs tested, 60 (19.8%) were polymorphic between the two parents, M35-1 and B35 of a recombinant inbred line (RIL) mapping population. A mapping population consisting of 500 RILs was developed using the above two parents, and a subset of random 245 RILs was used for genotyping with polymorphic SSRs. We developed a linkage map containing 231 markers, of which 228 (174 genomic and 54 genic) were microsatellites and three were morphological markers. Markers were distributed over 21 linkage groups, and spanned a genetic distance of 1235.5 cM. This map includes 81 new SSRs, of which 35 (21 unigene and 14 genomic) were developed in the present study and 46 from other studies. The order of the SSR markers mapped in the present study was confirmed physically by BLAST search against the whole-genome shotgun sequence of sorghum. Many unigene sequences used for marker development in this study include genes coding for important regulatory proteins and functional proteins that are involved in stress-related metabolism. The unigene SSR markers used together with other SSR markers to construct the sorghum genetic map will have applications in studies on comparative mapping, functional diversity analysis and association mapping, and for quantitative trait loci detection for drought and other agronomically important traits in sorghum.
A modified synthetic route to BMS-978587 was developed featuring a chemoselective nitro reduction and a stereospecific Suzuki coupling as the key bond formation steps. A systematic evaluation of the ...reaction conditions led to the identification of a robust catalyst/ligand/base combination to reproducibly effect the Suzuki reaction on large scale. The modified route avoided several challenges with the original synthesis and furnished the API in high overall yield and purity without recourse to chromatography.
Background
Acute pancreatitis (AP) is known to result in endocrine dysfunction (prediabetes, diabetes). The objective of this study was to determine the temporal incidence of endocrine dysfunction ...after onset of AP and determine the risk factors in Indian patients.
Methods
In this prospective study, enrolled patients diagnosed with AP between February 2019 and May 2019 were followed at 3, 6, and 12 months until May 2020. Patients with recurrent AP, chronic pancreatitis, and pre-existing endocrine dysfunction were excluded. Demographic and disease severity (clinical, laboratory, and radiological) data were recorded. Mann-Whitney
U
and Chi-square tests were used to compare groups. Temporal trend for development of endocrine dysfunction was evaluated using the Extended Mantel Haenszel Chi-square test for trend. Logistic regression was used to identify independent risk factors.
Results
Eighty-six patients (males 66, median IQR age 33.0 26.0–44.2 years) who fulfilled enrolment criteria were finally analyzed. The most common etiology was alcohol (
n
=31 36%) followed by gallstones (
n
=17 19.8%). The proportion of patients with moderately severe acute pancreatitis and severe AP were 59.3% and 15.1%, respectively. Overall, the frequency of prediabetes and diabetes increased temporally across the follow-up period. These were 2 (2.33%) and 1 (1.16%) at 3 months, 11 (12.8%) and 5 (5.81%) at 6 months, and 20 (23.2%) and 9 (10.5%) at 1 year, respectively. On multivariable logistic regression, intervention for walled-off necrosis (WON) emerged as the single independent risk factor for endocrine dysfunction (odds ratio 9.01 2.3–35.5;
p
=0.002).
Conclusions
Endocrine dysfunction is frequent after an episode of AP. Intervention for WON is an independent risk factor for endocrine dysfunction.
Role of an engineer is imperative in improving the quality of human life and India is one of the largest producers of engineers with 23 IITs (Indian Institute of Technology), 31 NITs (National ...Institute of Technology) and state universities offer technical education in the form of undergraduate, graduate and postgraduate programs. Since India, a predominantly young population, IITs and NITs are not sufficient in number and hence AICTE (All India Council for Technical Education) has approved over ten thousand self-financed private engineering colleges across the country to cater the huge demand for engineering education. Except for IITs, NITs, and other premier institutes, most engineering colleges failed to give quality education to the students, which would get them suitable jobs. As per the research carried out by Aspiring Minds a leading employability assessment company, only 1.7 percent of the engineering graduates are suitable for the new age jobs and top 10 IT companies recruit only 7 percent of the engineering graduates every year which is a serious concern. 1
This paper deals with the heat and mass transfer in unsteady flow of Powell-Eyring fluid past an inclined stretching sheet in the presence of radiation, non-uniform heat source/sink and chemical ...reaction with suction/injection effects. The governing equations are reduced into system of ordinary differential equations using similarity transformation and solved numerically using Runge-Kutta based shooting technique. Results display the influence of governing parameters on the flow, heat and mass transfer, friction factor, local Nusselt and Sherwood numbers. Comparisons are made with the existed studies. Present results have an excellent agreement with the existed studies. Results indicate that an increase in the chemical reaction parameter depreciates the friction factor, heat transfer rate and enhances the mass transfer rate. Dual solutions exist only for certain range of suction/injection parameters.
We report a simple method to prepare hydrotalcites involving both urea hydrolysis and hydrothermal synthetic conditions. Out of a series of Mg/Al ratios tried, pure hydrotalcite like phase was ...obtained for Mg/Al ratios of 1:1 and 2:1. Unlike in conventional co-precipitation method we succeeded in preparing Mg/Al ratio of 1:1 by this route. The high temperature (180
°C) applied and pressure developed in the autoclave during the synthesis might have altered the topochemical transformation. The materials were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, Fourier transform infrared, thermo gravimetric and differential thermal analysis and transmission electron microscopy.
