Utilization of High-pressure Suction power regarding EBUS-TBNA Sample throughout Assumed United states.
We studied the physio-biochemical involvement of exogenous signaling compounds, glutathione and putrescine (alone and in combination), on three contrasting genotypes (cvs. Shiralee, Rainbow, and Dunkled) of canola (Brassica napus L.) of plants exposed to chromium stress. Seeds were germinated in Cr-contaminated soil (0 and 50 μg/g Cr6+), and both signaling compounds were applied as a foliar spray to 20-day-old plants. Changes in root, stem, and leaf nitro-oxidative metabolism, endogenous GSH level, secondary metabolites, and mineral nutrients were investigated from 60-day-old plants. Exposure to Cr6+ increased stem GSH and NO concentrations in all cultivars. Maximum root Cr6+ bioaccumulation was recorded in cv. Rainbow and the least in cv. Shiralee. learn more Also, Cr6+ stress decreased number and weight of seeds and pod length. Disturbances in root and shoot mineral profile were evident; however, its magnitude varied in all cultivars. The exogenous GSH improved root and shoot P, Fe, S, and Zn concentrations; however, the effect was cultivar specific. Leaf endogenous GSH was increased by exogenous GSH while NO levels remained unaffected. The GSH application also promoted shoot Cr6+ bioaccumulation while PUT application caused a recovery in seed number and seed weight. Both PUT and GSH differentially affected tissue-specific secondary metabolite profile. Overall, the exogenous GSH was much more effective in alleviating the Cr+6 toxicity in canola.Desulfurization of liquid fuels mitigates the amount of noxious sulfur oxides and particulates released during fuel combustion. Existing literature on oxidative-adsorptive desulfurization technologies focus on sulfur-in-fuel removal by various materials, but very little information is presented about their desorption kinetics and thermodynamics. Herein, we report for the first time, the mechanism of sulfur desorption from neutral activated alumina saturated with dibenzothiophene sulfone. Batch experiments were conducted to examine the effects of agitation rate, desorption temperature, sulfur content, and eluent type on sulfur desorption efficiencies. Results show enhanced desorption capacities at higher agitation rate, desorption temperature, and initial sulfur content. Desorption efficiency and capacity of acetone were found to be remarkably superior to ethanol, acetoneethanol (11), and acetoneisopropanol (11). Desorption kinetics reveal excellent fit of the nonlinear pseudo-second-order equation on desorption data, indicating chemisorption as the rate-determining step. Results of the thermodynamics study show the spontaneous (ΔG° ≤ -2.08 kJ mol-1) and endothermic (ΔH° = 32.35 kJ mol-1) nature of sulfur desorption using acetone as eluent. Maximum regeneration efficiency was attained at 93% after washing the spent adsorbent with acetone followed by oven-drying. Scanning electron microscopy, Fourier transform infrared, and X-ray diffraction spectroscopy analyses reveal the intact and undamaged structure of neutral activated alumina even after adsorbent regeneration. Overall, the present work demonstrates the viability of neutral activated alumina as an efficient and reusable adsorbent for the removal of sulfur compounds from liquid fossil fuels.Among various types of renewable energy, geothermal energy is recognized as an effective method for supplying thermal energy. Ground heat exchangers, as the main part of a geothermal energy system, are utilized for the extraction of the heat from the ground. Helical-shaped geothermal heat exchangers are very popular in this field as they need less land space compared to the other traditional straight ones. They have simple assembly and a high density of coils in their configuration. Considerable efforts have been done on the development of this type of geothermal heat exchanger. However, this topic has not been subject to a review. To address this issue, we present an overview of the potentials and challenges of helical-shaped geothermal heat exchangers in this study. The environmental and economic aspects, recent progress about the numerical simulations, soil features, different types and arrangements, and geometrical parameters for this type of heat exchangers are investigated. The installation cost is a critical challenge in the practical applications of these exchangers. However, the previous studies are mostly focused on the technical evaluation and optimization of the thermal performance of this type of heat exchanger, while little attention is paid to their installation costs. It is essential to understand the potential environmental impacts of each renewable energy technology to have a correct evaluation of the system. The life cycle assessment can be used as a proper method to assess the environmental issues of the helical-shaped geothermal heat exchanger in the studies.The present investigation was conducted to estimate the acute toxicity of Thymus linearis plant extract, its effect on hemato-biochemical parameters and behavioural response in the golden mahseer (Tor putitora). The phytochemical composition present in T. linearis plant extrat were Alkaloids, Flavonoids, Phenols and Tannin. The fishes were subjected to eight different concentrations of T. linearis leaves extract (8.25, 8.50, 8.75, 9.00, 9.25, 9.50 and 9.75 mg/kg) and the control group without plant extract for 96-h LD50 study. The mortality was recorded every 24 h post-treatment. Minimum mortality was recorded in the 8.25 mg/kg, whereas 100% mortality was recorded in the 9.75 mg/kg T. linearis extract after 96-h periods. The LD50 was estimated by probit analysis, and the value of T. linearis at 96 h was found to be 8.71 mg/kg for golden mahseer. A non-lethal dose of 1/10th of 96-h LD50 value (0.87 mg/kg) was taken for the sublethal study. After 96 h, the red blood cell (RBC), white blood cell (WBC), haemoglobin (Hb), packed cell volume (PCV) and blood glucose were measured. RBC (×106/mm3), Hb (%) and PCV (%) significantly decreased at 8.25, 8.50, 8.75, 9.00 mg/kg, but WBC and blood glucose significantly increase at 8.25, 8.50, 8.75, 9.00 mg/kg of T. linearis plant extract. The observations on behaviour response of golden mahseer were also recorded. In the present study, the acute toxicity of wild ajwain was more significant than short-term toxicity. The mortality rate was very high during the study period of T. linearis exposure.
