Sustaining Productivity in Aonla Based Hortipasture System through \u3cem\u3eIn-Situ\u3c/em\u3e Soil Moisture Conservation in Semi-Arid Region of India

Globally land degradation affects about one sixth of the world population. In India, about 120 m ha area is affected with different kinds of land degradation. Under such situation, horti-pasture system provides best and economic alternative in conjunction with in-situ soil moisture conservation in general and semi-arid tropics in particular. India supports 55% buffaloes, 16% cattle, 20 % goats and about 4% sheep with deficit of 35% green fodder (525.51 mt), 10% dry fodder (453.28 mt) and 44% feed (28.4 mt) (IGFRI Vision, 2050). The per capita/day availability of fruits is 85 g as compared to average requirement of 120 g (CISH Vision, 2050). The above target could be achieved through adopting horti-pasture system in degraded land in combination of in-situ moisture conservation practices with suitable fruit and forage specie. Aonla (Emblica officinalis Gaertn.) is an important fruit crop and grown commercially because of its high economic return, therapeutic and neutraceutical value and its suitability for marginal lands (Kumar and Chaubey, 2008). Stylosanthes seabrana is perennial legume having good persistency under semi-arid condition and well adapted to tropical and subtropical environments with summer-dominant rainfall between 500-1,000 mm and very drought tolerant (Maass and Mannetje, 2002). Cenchrus ciliaris is also an important pasture easy to establish and provides comparatively high value forage suitable for direct feeding as well as quality hay (Trivedi, 2010). Establishment of hortipasture system in semi-arid tropicsis challenging task due to topography, soil and water related constraints. In-situ soil moisture conservation facilitates surface water to concentrate in one area, around the base of a newly planted tree (Samra, 2010 and Singh et al., 2008). Keeping above facts in view an experiment was conducted to evaluate different soil and moisture conservation measures for sustaining productivity with Aonla based hortipasture system at experimental farm of IGFRI, Jhansi, U. P. India

Long Term Air Quality Analysis in Reference to Thermal Power Plants Using Satellite Data in Singrauli Region, India

The exponentially growing population and related anthropogenic activities have led to modifications in local environment. The change in local environment, evolving pattern of land use, concentrations of greenhouse gases and aerosols alter the energy balance of our climate system. This alteration in climate is leading to pre-mature deaths worldwide. This study analyses the air quality of Singrauli region, Madhya Pradesh, India for the past 15 years. Otherwise known as Urjanchal “the energy capital” of India has been declared as critically polluted by CPCB. The study provides an updated list of thermal power plants in the study area and their emission effects on the local environment. The pollutants analyzed in the study are carbon dioxide, methane, nitrogen dioxide, Sulphur dioxide and particulate matter. Long term remotely sensed data was obtained from NASA Giovanni for past 15 years. Statistical analysis is used to characterize seasonal and annual variations of trace gases in the study area. The study concluded that Methane, Carbon dioxide, Nitrogen dioxide and Sulphur dioxide are on an increasing trend with an average rate of 1.03, 0.99, 2.15 and 1.09 annually. Secondly, Methane & SO2, PM2.5 & NO2, PM10 & NO2, CO2 & Methane and PM2.5 & PM10 have strong correlations with a 95% significance. Furthermore, Methane, SO2 and CO2 exhibit cyclic variation with change in season. The study also indicated that maximum aerosols present in the study area are a result of anthropogenic activities

Dynamic Characteristics of Aerosol Optical Properties over Dibrugarh City in the North-Eastern Indian Region during 2018–2021

Aerosols play an important role in the earth\u27s environment across the globe through their involvement in various earth system cycles. The change in the aerosol properties may cause short and long-term impacts, the knowledge of such changes is useful in the estimation of the pollution sources of any region. We have carried out the analysis of the aerosols\u27 optical and radiative properties using AERONET station data from 2018 to 2021 in Dibrugarh City. The higher Aerosol Optical Depth (AOD) values during winter and pre-monsoon months indicate high anthropogenic activities, and biomass burning in Dibrugarh. The impact of various sources and daily meteorological parameters help in understanding the diurnal variations of the AOD, Ångström Exponent (AE), and column water (CW). Fine aerosol fractions dominate the aerosol volume, but sometimes the long-range transport of dust affects aerosol properties during pre-monsoon months (MAM). MODIS-derived AOD and AERONET AOD values show a good correlation, with R2 = 0.68. The highest volume of the aerosols reaches up to 0.11 µm3 µm–2 during pre-monsoon months, whereas it lies below 0.05 µm3 µm–2 in other seasons. SSA values indicate the presence of scattering aerosols but in 2020, a sudden decline in the SSA values shows a strong rise in the absorbing aerosols. Throughout the study period (2018–2021), the positive radiative forcing indicates a rise in atmospheric heating

A review on the important phytochemicals and their role in psoriasis

Psoriasis may emerge at any stage of life irrespective of age, sex or geographic location. It is identified as a chronic immune-linked inflammatory skin disease that affects all human races. Psoriasis is often more Caucasian than non-Caucasian groups of human races and in geographic areas, like higher latitudes and Western countries. Therefore, attention should be paid to both genetic and environmental causes of psoriasis. Natural products have significantly contributed and encouraged the advances in skin disease treatment like psoriasis. The maximum number of phytochemicals is now being used worldwide, including various plants, herbs, and formulations. In addition, some phytochemicals like psoralen, aloe-emodin, curcumin etc. have also been isolated in pure form and have also shown their efficacy in the management of psoriasis. The presence of such phytochemicals confirms the effectiveness of few herbal therapies. This paper reviews some of the promising phytochemicals and their potential molecular target sites and mechanism of action, which may aid in designing and producing more precise and selective antipsoriatic agents. Exploring and recognizing phytochemicals as to how they function will facilitate more site-specific delivery methods for psoriasis care

Analysis of Air and Soil Quality around Thermal Power Plants and Coal Mines of Singrauli Region, India

Singrauli region is known as the energy capital of India, as it generates nearly 21 GW of electricity, supplied to various parts of the northern India. Many coal-based Thermal Power Plants (TPPs) using coal from several nearby coal mines, and numerous industries are set up in this region which has made it as one of the highly polluted regions of India. In the present study, detailed temporal analysis and forecast of carbon dioxide (CO2), nitrogen dioxide (NO2), sulfur dioxide (SO2), and methane (CH4) concentrations retrieved from satellite data have been carried out for the periods 2005–2020. Based on the classical multiplicative model and using linear regression, the maximum concentration of CO2, NO2, SO2, and CH4 in the year 2025 is found to be 422.59 ppm, 29.28 ppm, 0.23 DU, and 1901.35 ppbv, respectively. Detailed analysis shows that carbon dioxide has a 95% correlation with all other trace gases. We have also carried out the geo-accumulation index for the presence of various contaminants in the soil of this region. The geo-accumulation index shows that soil in and around thermal power plants and coal mines is contaminated by heavy metals. The cumulative index shows that soil around Hindalco industries, Bina coal mines, Khadia coal mines, and coal-based TPPs (Anpara and Vindhayachal) are highly polluted and a threat to human population living in the region

The enterolith causing jejunal obstruction, an unusual presentation: A case report

Enteroliths are a rare cause of intestinal obstruction. Patients can present with repeated episodes of intestinal obstruction as long as an enterolith is able to pass through the gut and then suddenly, they get stuck at the terminal ileum or present with the perforation peritonitis, as may happen in case of a diverticular disease. Here, we report the case of a young male presented to the emergency room with acute intestinal obstruction. During the explorative laparotomy, an enterolith was found stuck inside the proximal jejunum which was removed through an enterotomy. This was an interesting case, as the patient did not have any predisposing factors nor did we find any evidence of other pathologies intraoperatively. Moreover, the enterolith was stuck in jejunum, contrary to the belief that terminal part of the ileum is a most common site for the enteroliths to get stuck

Modulation of Hypoxia-Induced Pulmonary Vascular Leakage in Rats by Seabuckthorn (Hippophae rhamnoides L.)

Cerebral and pulmonary syndromes may develop in unacclimatized individuals shortly after ascent to high altitude resulting in high altitude illness, which may occur due to extravasation of fluid from intra to extravascular space in the brain, lungs and peripheral tissues. The objective of the present study was to evaluate the potential of seabuckthorn (SBT) (Hippophae rhamnoides L.) leaf extract (LE) in curtailing hypoxia-induced transvascular permeability in the lungs by measuring lung water content, leakage of fluorescein dye into the lungs and further confirmation by quantitation of albumin and protein in the bronchoalveolar lavage fluid (BALF). Exposure of rats to hypoxia caused a significant increase in the transvascular leakage in the lungs. The SBT LE treated animals showed a significant decrease in hypoxia-induced vascular permeability evidenced by decreased water content and fluorescein leakage in the lungs and decreased albumin and protein content in the BALF. The SBT extract was also able to significantly attenuate hypoxia-induced increase in the levels of proinflammatory cytokines and decrease hypoxia-induced oxidative stress by stabilizing the levels of reduced glutathione and antioxidant enzymes. Pretreatment of the extract also resulted in a significant decrease in the circulatory catecholamines and significant increase in the vasorelaxation of the pulmonary arterial rings as compared with the controls. Further, the extract significantly attenuated hypoxia-induced increase in the VEGF levels in the plasma, BALF (ELISA) and lungs (immunohistochemistry). These observations suggest that SBT LE is able to provide significant protection against hypoxia-induced pulmonary vascular leakage
