Meissner response of a bulk superconductor with an embedded sheet of reduced penetration depth

We calculate the change in susceptibility resulting from a thin sheet with reduced penetration depth embedded perpendicular to the surface of an isotropic superconductor, in a geometry applicable to scanning Superconducting QUantum Interference Device (SQUID) microscopy, by numerically solving Maxwell's and London's equations using the finite element method. The predicted stripes in susceptibility agree well in shape with the observations of Kalisky et al. of enhanced susceptibility above twin planes in the underdoped pnictide superconductor Ba(Fe1-xCox)2As2 (Ba-122). By comparing the predicted stripe amplitudes with experiment and using the London relation between penetration depth and superfluid density, we estimate the enhanced Cooper pair density on the twin planes, and the barrier force for a vortex to cross a twin plane. Fits to the observed temperature dependence of the stripe amplitude suggest that the twin planes have a higher critical temperature than the bulk, although stripes are not observed above the bulk critical temperature.Comment: 16 pages, 9 figure

Identification of heat-tolerant rice genotypes and their molecular characterisation using SSR markers

The effect of high-temperature stress has a critical impact in causing reduced crop yield. The focus of the current investigation is the identification of heat-tolerant rice varieties that can alleviate the effects of stress. Among the ten genotypes evaluated across various parameters such as leaf area, dry weight, photosynthetic rate, stomatal conductance and spikelet fertility, N-22 showed superior characteristics for the grain filling parameters along with CR-Dhan 307. The variety CR-Dhan 307 with significantly higher mean pollen viability (80.23%), spikelet fertility (81.18%) and 1000 grain weight (25.45 gm) can be utilized as a heat-tolerant variety. Other genotypes Ptb-7 and CR-Dhan 202 seemed to have tolerance traits beneficial at the vegetative stage. The genotype Rajalakshmi can be characterised as heat susceptible as it had significantly lower values for all parameters. Polymorphic analysis was carried out to validate SSR markers associated with heat tolerance. The polymorphic information content (PIC) was found to be the highest for RM236 and RM6100. The SSR marker RM6100 has been validated in the current investigation to be associated with heat tolerance. As the PIC value is an indication of the ability of the marker in indicating genetic diversity, the PIC values of the 11 polymorphic markers is useful for identify heat-tolerant genotypes. The genetic diversity analysis was carried out using DendroUPGMA to establish the relationship between the genotypes. The genotypes Ptb-7 and CR-Dhan 204 were thus found to be closely related to the heat-tolerant check variety, N-22 indicating genetically related traits for tolerance to heat

Marine fisheries in Kerala - an overview

The state of Kerala, located at the extreme southern narrow strip of the Indian sub-continent is wedged between the Arabian Sea to the west and the Western Ghats to the east. It is lying between 8°18', 12° 48' north latitudes and 74° 52', 77° 22' east longitudes. Kerala coast runs for about 590 km with 190 landing centres spreading over nine coastal districts

Ingestion of a Nutritional Supplement Pre-Workout Will Increase Exercise Time-to-Fatigue

Everyone fatigues at the end of an intense exercise bout. However, previous research has indicated that ingestion of a mixed nutrient supplement one hour pre-exercise will increase exercise time-to-fatigue¹. For this experiment, four females between the ages 20-50 participated in a controlled pilot study. Exercise was performed using a row machine, where time- to-fatigue was measured from a baseline of 80% max HR (220 minus age). The nutrient supplement was ingested 1 hour pre-rowing and contained 30g of protein, 5g carbohydrate, and 3g of fat. Results showed that pre-exercise ingestion of a mixed protein supplement did increase row time-to-fatigue

An Appraisal of the Marine Fisheries of Karnataka and Goa

Karnataka, on the West coast, plays an important role in the fisheries development of India and has a prominent place in the country's fisheries map, It has a shelf area of 25000 Sq. Km. and a coastline of 270 Km, about 1/22 of the country's coastline. The State's contribution to the total marine fish production in the country is of the order of ^.0%. The State has two coastal districts, namely Dakshin Kannada and Uttar Kannada. The lengths of coastline of both the districts are almost the same. Many rivers such as the Nethravathi, the Saravathi and the Kali flow into the Arabian sea and render the inshore area rich in nutrients

Sea truth data collection: estimation of diffuse attenuation coefficient in ocean colour mapping

Phytoplankton pigments in the ocean waters are the prime synthesisers in marine food chain which in turn terminate as pelagic or benthic nekton. They perform about half of the total global photosynthesis and compr is ethe upper consumption and production. These are the substances that have definite spectral characteristics and thereby govern the ocean colour

Assessment of growth responses of Wistar rats fed with a diet containing composite flour premix

Composite flour technology involves the process of mixing cereals and legumes to facilitate the usage of locally available raw materials to produce high-quality food products economically. The present investigation evaluated the growth responses of a composite flour blend formulated using selected cereals, pulses and oil seed (a total of nine grains) were evaluated in two-month-old growing Wistar rats. The feeding trial was conducted for four weeks after an acclimatization period of five days. Daily feed intake and weekly body weight were recorded and parameters such as weight gain, feed conversion efficiency and digestibility of protein were estimated. A significantly higher average final live weight, weekly weight gain and better feed conversion efficiency (p<0.05) were observed in the treatment group. The observed values of digestibility of protein were 84.74 ± 0.85 % and 65.16 ± 0.89 % respectively for the treatment and control diets. Data were analyzed statistically using Analysis of Variance in SPSS 24 software. The investigation revealed that the formulated composite flour premix promotes growth with good protein digestibility in rats and could be used for nutraceutical fortifications to support human life and good health
