Biochemical composition of promising leaves genotypes of buckwheat grown in Himachal Pradesh
Buckwheat originated from China and being cultivated all over the world, and has become a prominent pseudocereal. Among the pseudocereals (amaranthus, buckwheat and quinoa), buckwheat plant is economically important primarily due to their carbohydrate and protein rich grains, short growth span; besides foliage being used as a green vegetable and commercial source of the glycoside rutin used in medicine. In the present study, an attempt was made to evaluate the biochemical constituents of nutritional and nutraceutical significance of fourteen promising leaves genotypes of common buckwheat grown in Sangla region by following standard procedures. Wide variations in moisture content, crude protein, fat, ash, crude fiber, carbohydrates, ascorbic acid, oxalate and in vitro protein digestibility were observed to range from 87.4 to 92.2 %, 22.4 to 30.4 %, 1.8 to 3.7 %, 10.6 to 15.4 %, 12.0 to 13.9 %, 34.8 to 42.4 %, 25.0 to 29.2 mg/100g, 1375 to 1390 mg/100g and 53.4 to 65.1 % in that order. The content of minerals such as potassium, phosphorus, calcium, magnesium, zinc, manganese and copper varied from 1767.5 to 2035.0 mg/100g, 808 to 910 mg/100g, 394 to 409 mg/100g, 232.0 to 248.2 mg/100g, 3.1 to 6.1 mg/100g, 20.4 to 29.8 mg/100g and 0.2 to 1.4 mg/100g respectively. Based on cumulative grading done in respect of nutritionally desirable quality i.e., protein, ash, crude fiber, carbohydrates, ascorbic acid, in vitro protein digestibility, calcium, phosphorus, iron and oxalate content, the genotype IC-323731 followed by Kullugangetri and VL-27 emerged out to be overall superior versatile cultivars for cultivation under dry temperate climate
Inquietud: Año IV Número 41 - (18/11/52)
Several experimental techniques are available to investigate materials but microscopic techniques based on hyperfine interaction form a subclass that can characterize materials at the smallest possible atomic scale. The interaction of the nuclear electromagnetic moments with the hyperfine fields arising from the extranuclear electronic charges and spin distributions forms the basis of hyperfine methods. In this review article, one of the hyperfine methods, known as perturbed angular correlation (PAC), has been described as it provides local-scale fingerprints about the formation, identification, and lattice environment of defects and/or defect complexes in semiconductors at the PAC probe site. In particular, the potential of the PAC technique has been demonstrated in terms of measured electric field gradient, its orientation, and the symmetry at the probe site for a variety of defects in semiconductors such as Si, InP, GaAs, InAs, ZnO, GaP, and InN
Docosahexaenoic acid supplementation: a need or a commercial hype?
Docosahexaenoic acid (DHA) is an important component of the brain and is essential critical for optimal brain health and function. With revealing of its beneficial effects on cognitive function, neurological, cardiovascular system and anti-inflammatory benefits, DHA has recently gained huge attention. As a result, the market is stocked with products supplemented with DHA claiming various health benefits. This review attempts to elucidate the current findings of DHA supplementation as a pharmacological agent with both preventive and therapeutic value
Non-linear characteristics in two-dimensional superconductors: Berezinskii-Kosterlitz-Thouless physics vs inhomogeneity
One of the hallmarks of the Berezinskii-Kosterlitz-Thouless (BKT) transition
in two-dimensional (2D) superconductors is the universal jump of the superfluid
density, that can be indirectly probed via the non-linear exponent of the
current-voltage characteristics. Here, we compare the experimental
measurements of characteristics in two cases, namely NbN thin films and
SrTiO-based interfaces. While the former display a paradigmatic example of
BKT-like non-linear effects, the latter do not seem to justify a BKT analysis.
Rather, the observed characteristics can be well reproduced theoretically
by modelling the effect of mesoscopic inhomogeneity of the superconducting
state. Our results offer an alternative perspective on the spontaneous
fragmentation of the superconducting background in confined 2D systems.Comment: Final version, as publishe
Competition between electron pairing and phase coherence in superconducting interfaces
In LaAlO3/SrTiO3 heterostructures, a gate tunable superconducting electron gas is confined in a quantum well at the interface between two insulating oxides. Remarkably, the gas coexists with both magnetism and strong Rashba spin–orbit coupling. However, both the origin of superconductivity and the nature of the transition to the normal state over the whole doping range remain elusive. Here we use resonant microwave transport to extract the superfluid stiffness and the superconducting gap energy of the LaAlO3/SrTiO3 interface as a function of carrier density. We show that the superconducting phase diagram of this system is controlled by the competition between electron pairing and phase coherence. The analysis of the superfluid density reveals that only a very small fraction of the electrons condenses into the superconducting state. We propose that this corresponds to the weak filling of high- energy dxz/dyz bands in the quantum well, more apt to host superconductivity
Six-minute walk work in patients with chronic obstructive pulmonary disease
Background:Six Minute Walk Test (6MWT) has demonstrated good reliability and validity as an assessment for exercise tolerance for moderate to severe COPD. 6MWD is a known to be a preferred outcome for this test; however, it does not account for differences in body weight that are known to influence exercise capacity.Aim of current study was to correlate of distance product (6MWWORK) with various variables in study group of patients with Chronic Obstructive Pulmonary Disease (COPD).Methods:Sixty patients of diagnosed COPD underwent pulmonary function test and 6MWT. Correlation coefficients were calculated for the 6-Min Walk Distance (6MWD) and 6MWORK with variables of pulmonary function and 6MWT.Results:The mean of 6MWD was 312.0 ± 21.2 meters and mean 6MWWORK was 31246 ± 2414 kg.m in the study population. 6MWD significantly correlated with age (r = 0.25), height (r = 0.42), body mass index (r = -0.32) and body weight (r = 0.48). 6MWORK yielded higher correlation coefficients than did 6MWD when correlated with FEV (r = 0.66 vs. 0.35), FEV1/FVC ratio (-0.46 vs. -0.24). The ROC curve demonstrated that 6MWORK had a significantly larger calculated area under the curve (P <0.05) than 6MWD with FEV1.Conclusion: 6MWWORK is an improved outcome of 6MWT to monitor functional capacity in patients of chronic obstructive pulmonary disease.
