In the hill areas, the traditional systems of dependence on forest usufructs like fuel for their households and fodder for their livestock has an important bearing on the status of Himalayan watersheds. The population of livestock is therefore also significant. The fuel and fodder requirements of the hill people are important routine activities for which women/ children spend long hours of their day-to-day life. But this regular collection of the fuel and fodder from the different land use categories in close proximity of villages. These activities have been an important factor for causing soil erosion, low fertility of the land and other degradation processes. The situation is further aggravated if animals are not stall-fed but are allowed to graze. To assess these scenarios, a comparative study of the ten villages in Arnigad Watershed, Mussoorie (Uttarakhand) has been done. The results of this study provide a macro view of the societal dependence on the different land use categories in the watershed with reference to fuel, fodder consumption and livestock scenario in the individual villages as well as the watershed.Keywords

Heart rate recovery 1-3 can be defined as the rate at which the heart rate (HR) declines from either maximal or sub-maximal exercise to resting levels and has been identified as a powerful and independent predictor of cardiovascular and all-cause mortality in healthy adults. Delayed heart rate recovery (HRR) after exercise is a function of vagal reactivation, and it is a predictor of overall mortality and adverse cardiovascular events. In patients with unknown Coronary Artery Disease (CAD) who underwent symptom limited exercise stress testing, HRR was influenced by age, male sex, hypertension, and the presence of provoked ischemia, use of a-blocker, calcium channel blocker and aspirin.References

Management of groundwater resource is determined by its accessibility and utility in terms of quantity and quality. The results of chemical analysis for pH, electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), total alkalinity (TA), calcium (Ca+2), magnesium (Mg+2), sodium (Na+), potassium (K+), chloride (Cl-), nitrate (NO3 -), sulphate (SO4 -2) and fluoride (F-) of 18 water samples collected from Lalsot urban area in Dausa district are presented. Based on the results, certain parameters like sodium adsorption ratio (SAR) and percent sodium (% Na) were also calculated. Statistical analyses have been carried out using chemical data to classify geo-chemical evaluation of the aquifer system based on the ionic constituents. Salinity and nitrate contamination are the two major problems in the area, which is alarming considering the use of this water for drinking. The major factors influencing the water quality are local geo-chemical formation, water-rock interaction, flow direction of groundwater and rainfall that control the overall mineralization.Keywords

A reassessment of the recent palaeomagnetic data on Proterozoic mafic dykes in the Bundelkhand and Bastar cratons permits a robust estimate of 1.466 Ga (Calymmian) pole (λ = 49.4°N; Φ; = 132.9°E; A95 = 6.6°; N = 11) for the Indian shield. The pole corresponds to a mean direction of D = 40.5°; I = 56.4° (α95 = 5.5°; K = 70). The Indian pole at c. 1.65 Ga (Statherian) is suggested to have been situated at λ = 59.6°N and Φ = 47.9°E (A95 = 8.1°; N = 6); it is estimated from a mean direction of D = 336.4°; I = 66.0°N (α95 = 5.3°; K = 159). The 1.466-Ga-old dykes are confined to the Eastern Ghats orogenic front in the easternmost part of the Bastar craton. Geochemically, the shoshonitic/high-K calc-alkaline affinity of these dykes is uniquely distinct from the tholeiitic composition found in Mesoor Palaeoproterozoic dykes in other parts of the Indian shield. Testing the existing pre-Rodinia Mesoproterozoic tectonic reconstructions negates the Columbia reconstructions in which the Indian shield is shown in juxtaposition with North China/Laurentia. On the other hand, palaeomagnetic and geological data suggest that the linkages between the Indian shield and Western Australia proposed earlier for the Palaeoproterozoic appear to persist during the Mesoproterozoic as well. The linkages may be further extended into Baltica.Keywords

An experiment was carried out to study the effect of different essential oils on enzymatic activity of stored oyster mushroom (Pleurotus florida). The harvested fruiting body was treated with four essential oils, i.e. lemongrass oil, citronella oil, mint oil and clove oil at two different concentrations – 5 and 10 μl – to test the total phenol content (TPC) and activity of three important enzymes, viz. phenylalanine ammonia lyase (PAL), peroxidase (POD) and polyphenol oxidase (PPO) that are involved in post-harvest quality preservation of mushrooms. TPC (0.286 mg/g), PAL content (0.038 μM/g), PPO content (0.042 U/mg) and POD content (0.38 U/mg) were found significant in mint oiltreated mushroom at 10 μl concentration. TPC and PAL content were higher in essential oil-treated mushrooms compared to the control samples, whereas PPO and POD contents were lower in the treated samples, signifying that essential oils treatment had a positive impact on the quality of harvested mushrooms. This preservative technique will help in increasing the shelf-life of harvested fruiting bodies.Keywords
