Sub-Doppler excitation spectroscopy in a collimated cold supersonic beam of 5% NO seeded in argon has been performed with a spectral resolution down to 10 MHz for four vibronic bands within the perturbed B ?X A system of NO . The rotational temperature of about 15 K achieved by adiabatic cooling allows the separation of closely lying vibronic bands which overlap in absorption spectra ...
معادن سنگ آهن سنگان واقع در 40 کیلومتری جنوب شرق خواف با ذخیره احتمالی 2/1میلیارد تن و استخراج سالیانه بالغ بر 5/3 میلیون تن یکی از بزرگترین معادن سنگ آهن در خاورمیانه است که به صورت روباز پلکانی استخراج می شود. بارگیری در این معدن و در زون¬های مختلف، بوسیله بارکننده¬های 1250 ،800، 600 و 320 کوماتسو انجام می¬گیرد. عواملی همچون قطعات سنگ¬های بزرگ ایجاد شده در فرایند آتشکاری، عدم دقت و نظارت در...
Formation of atelectasis is one mechanism of impaired gas exchange during general anaesthesia. We have studied manoeuvres to re-expand such atelectasis in 16 consecutive, anaesthetized adults with healthy lungs. In group 1 (10 patients), the lungs were inflated stepwise to an airway pressure (Paw) of 10, 20, 30 and 40 cm H2O. In group 2 (six patients), three repeated inflations up to Paw = 30 c...
Abstract The energy demand is on the global increase as world economy increasing steadily. Hence, need to develop energy-saving technology with local raw materials and abundant waste becomes paramount. mixtures of Enugu Iva-pottery clay, Nsu clay PKS were evaluated improve quality locally produced refractory for pyro-processing industries. chemical mineralogical composition determined. Eight re...
Plant roots and biochar amendment cause changes in soil structure hydraulic properties; however, their interactive influences are still inadequately understood. A six-year field study was conducted on hillslope farmland the Sichuan basin, China, to evaluate how honeysuckle planting application affect properties. Various parameters related (soil organic matter (SOM), aggregate stability, bulk de...
Over the years, the role of Traditional and Complementary Medicine (T/CM) in maintaining human health has significantly growing and could no longer be ignored. The World Health Organisation also recognised its contribution and encourages the member countries to integrate proven safe and effective traditional medicine into the national health care delivery. Unlike modern medicine, which is intro...

This study explored the influence of moringa (Moringa oleifera; MO) foliage supplementation on in vitro ruminalgas production kinetics and substrate degradation cattle. In fermentation was carried out with twotypes substrates, viz. wheat straw (WS) WS plus concentrate mixture (CM; 60:40) cattle rumen inoculum.The MO incorporated to both substrates at 0, 5, 10, 20, 30, 40 50% levels total dry ma...
OBJECTIVES Data on management of esophageal narrowing related to eosinophilic esophagitis (EoE) in children are scanty. The aim of the present study is to assess the safety and effectiveness of esophageal dilation in pediatric EoE from the largest case series to date. METHODS Children diagnosed with EoE during 2004 to 2015 were reviewed for the presence of esophageal narrowing. Esophageal nar...
Assessment of soil organic carbon (SOC) pool is an essential pace for understanding the sequestration potential (CSP) system as a mitigation strategy and also investigate that they act source or sink atmospheric CO2 subject to level saturation. Improved CSP has been recognized one possible solutions mitigating climate change. The community forests (CFs) in Nepal not well recognized. Therefore, ...
