In underground coal gasification (UCG), it is essential for UCG production to accurately control the temperature of gas produced at wellhead well and correctly calculate variation law field in whole wellbore. wellbore structures use three sprayed water cooling schemes. These schemes consider heat exchange mechanism between formation, division into spray chamber section non-spray section, establ...

This study aimed to comprehensively compare the general characteristics, lifestyles, serum parameters, ultrasonic cardiogram (UCG) parameters, depression, quality of life, and various comorbidities between empty nest and non-empty nest elderly among rural populations in northeast China. This analysis was based on our previous study which was conducted from January 2012 to August 2013, using a m...

AIMS Previous studies have shown that aortic valve calcification (AVC) was associated with cardiovascular events and mortality. On the other hand, periprocedural myocardial injury (PMI) in percutaneous coronary intervention (PCI) is a well-known predictor of subsequent mortality and poor clinical outcomes. The purpose of the study was to assess the hypothesis that the presence of AVC could pred...

Patients with chronic heart failure (CHF) experience progressive deterioration of functional capacity and quality of life (QoL). This prospective, randomized, controlled trial assesses the effect of exercise training (ET) protocol on functional capacity, rehospitalization, and QoL in CHF patients older than 70 years compared with a control group. A total of 343 elderly patients with stable CHF ...

Testing plays a major role for improving the quality of a software product. Due to its iterative and incremental nature it needs special attention. Test case generation is one of the complex activities carried out during testing phase. Generating test cases in the early phases of development life cycle works like a catalyst for model based testing and at the same time efficiently manages time a...

A conditional-lethal mutant was isolated as having a flagellar regulatory phenotype at 30 degrees C and being unable to grow at 42 degrees C. Chromosomal mapping localized the mutation to the serT gene, which encodes an essential serine tRNA species (tRNA((cmo)5UGA)(Ser)). DNA sequence analysis revealed the mutation to be a single base change in G:A at position 10 of the serT gene that lies wit...

A 40-year-old female w~th the left adrenal pheochoromocytoma showed ECG abnormalities and the clinical features similar to act.~te myocardial infarction. Enzymological studies and UCG findings in the acute phase revealed the same pattern as those in acute myocardial infarction. After finding the existence of the left adrenal pheochromocytoma, the differential diagnosis between myocardial infarc...

Abstract Background The Ugandan Ministry of Health decentralized mental healthcare to the district level; developed Uganda Clinical Guidelines (UCG); and trained primary health care (PHC) providers in identification, management, referral individuals with common disorders. This was intended promote integration services into PHC country. ‘Common disorders’ here refers mental, neurological substan...

The main goal of the study was the analysis of the parameters of wastewater generated during the ex situ underground coal gasification (UCG) experiments on lignite from Belchatow, and hard coal from Ziemowit and Bobrek coal mines, simulated in the ex situ reactor. The UCG wastewater may pose a potential threat to the groundwater since it contains high concentrations of inorganic (i.e., ammonia ...
