Abstract

A new technological solution to improve the process of oil displacement by water flood can be done by increasing the hydrodynamic pressure periodically. The proposed technology allows, to overcome the resistance of capillary forces and to widen the injection zone. The filtration experiments were conducted under conditions corresponding to the reservoir through a composite rock sample of cylindrical shape which is made from natural reservoir core deposits of Western Siberia. The proposed technique also allows to estimate the pressure distribution along the propagation of the formation on discrete areas of the reservoir as the displacement front moves, and so, the time frame of the hydrodynamic pressure drop changes. It also allows to determining the duration and phasing of pressure control in order to achieve the expected hydrodynamic effect and consequently, increase the flow of oil to the producing wells.

Abstract

This study assesses the role of domestic biogas plants in mitigation and adaptation to climate change through a case study of Gaikhur VDC in Gorkha District in Nepal. Comparing the biogas and non-biogas households, the study found that use of biogas contributed in mitigation of climate change through reduced emission of greenhouse gases, avoided the deforestation and increased the carbon capture. Application of biogas energy contributed towards improving the adaptation to climate change impacts through saving of household income, improved health, reduced hardship and saved time. Furthermore, biogas extended the opportunity of financial benefits through reduced emissions. Lack of knowledge on fertilizer value of bio-slurry has been the major cause of high payback period of initial investment made on biogas installation. Disclosing and analyzing the constraints accelerated the use of domestic biogas plants. This study suggests ways to overcome constraints and in enabling environment for the biogas sector.

Abstract

In this paper an attempt has been made to study the impact of surfactant on the properties of the ultrasonically spray deposited CuO films. An aqueous solution of cupric nitrate trihydrate (Cu(NO ) .3H O) modified with Sodium Dodecyl 3 2 2 Sulphate (SDS) surfactant is used to deposit CuO films on glass substrate by Ultrasonic spray pyrolysis technique. The X'Pert Panlytical Diffractometer was employed for the phase identification of the films using Cu Kα radiation (λ = 1.5405 Å, 30mA, 40 kV) in 2θ range from 30-80°. The Field Emission Scanning Electron Micrographs (FESEM) and EDAX (Energy Dispersive Analysis of X-rays) spectrum were recorded on JEOL JSM-6700F Scanning Electron Microscope with a beam voltage of 30 kV. The depth profiler (Dektek 3030 XT) was employed for monitoring the film thickness and was found to be 400 ± 20 nm. The X-Ray Diffraction (XRD) studies of the films deposited at various substrate temperatures indicate the formation of monoclinic CuO with preferential orientation along the(002) plane for all samples. Surfactant modified films showed an increase in crystallite size of 35 nm at substrate temperature of 300 °C. The Scanning Electron Micrograph (FESEM) confirms the uniform distribution of facets like grains on the entire area of substrate. The results obtained in this study illustrate that SDS modified films show a significant reduction in the particle agglomeration thereby increasing the surface to volume ratio which in turn improves their sensing performance.

Abstract

In this present study, a low cost adsorbent is prepared from naturally and abundantly available Indian gooseberry seed powder which is a non-conventional adsorbent and is biodegradable. Batch experiments are carried out to investigate the effect of various process parameters such as agitation time, the adsorbent size, adsorbent dosage, initial chromium concentration and the effect of pH solution . The maximum adsorption of chromium is obtained at pH value of 2. The equilibrium data for the adsorption of chromium on Indian gooseberry seed powder is tested with various adsorption isotherms such as ‘Langmuir’, ‘Freundlich’ and ‘Tempkin’ isotherms. The Langmuir and Freundlich were found to be significant for the removal of chromium (VI) using Indian gooseberry seed powder and the maximum metal uptake is found to be 38.46 mg/g at pH value of 2. The adsorption process follows the second order kinetics and corresponding constants are obtained. In this study, Indian gooseberry seed powder is an effective and affordable adsorbent for hexavalent chromium removal from industrial waste water.

Abstract

Assessment of impact of noise on sensitive area especially in hospital environment has become most crucial concern in the recent time. Cardiac patients are one of the most sensitive and worst affected due to noise pollution. A study is therefore conducted on 100 beds cardiac hospital with a focus to assess the noise level in the hospital environment. A 16- hours sound measurement study is done using sound level meter (DAWE Model No. 1421C) to ascertain the noise level. The results indicate that the noise levels exceeded the limit of noise level prescribed by the authority. There is a significant difference (p < 0.05) spatially and temporally, in the noise exposure levels at various locations within the hospital premises. Sound pressure levels (dBA) were measured at 30 minutes intervals in the vicinity of a hospital environment. The resultant time series is analyzed using the Auto Regressive Integrated Moving Averages (ARIMA) modeling technique. The time series is found to be non stationary. After first differencing, the transformed series becomes stationary and is found to be governed by a moving average process of order 1.
