Effect of Number and Size of Recess on the Performance of Hybrid (Hydrostatic/Hydrodynamic) Journal Bearing

AbstractThis paper describes a theoretical study concerning static performance of four pocket rectangular recess hybrid journal bearing. Effect of recess length and width variation, number of recess variation on the load bearing capacity and oil flow parameter for rectangular recess has been carried out. The Reynolds equation for non rotating recessed hybrid bearing was solved on a high speed computer satisfying appropriate boundary conditions and using finite difference method. Various results for different recess axial length to bearing axial length, different recess circumferential length to circumferential length of bearing, various L/D ratios and number of recesses are presented

Aeromonas caviae septicemia in immunocompetent gastrointestinal carriers

Aeromonas caviae strains have been isolated from blood and stool cultures of three immunocompetent patients, residents of Northern India, who presented with community acquired septicemia without any recent history of diarrhea. Cell culture infectivity test performed on Hep-2 cells have shown substantial degree of invasiveness in the isolated strains. This case unleashes a possibility of asymptomatic gastrointestinal carriage of such strains of A. caviae in a very large population of India, as several areas of India have very high rates of Aeromonas induced acute diarrhea/gastroenteritis (up to 13%). It needs to be appraised further in India as well as other countries having high rates of Aeromonas induced acute diarrhea/gastroenteritis

Not AvailableRice (Oryza sativa L.)–wheat (Trititicum aestivum L.) system (RWS) in South Asia is under stress, as nutrient removals by crops are higher than their replenishment through fertilizers. We evaluated improved nutrient management strategies at 10 different locations across the Indo-Gangetic Plains (IGP) of India and adjacent regions during 2003–04 to 2005–06, and compared the improved practices in terms of yield gain, nutrient use efficiency and economic returns, with existing farmers fertilizer practices (FFP), and state recommended fertilizer rates by the government departments (SR). Improved N–P–K application rates were calculated by accounting for the indigenous nutrient supply (INS), yield target and crop nutrient demand as a function of the interactions between N, P and K. Compared with the SR and FFP, improved practices increased average grain yield from 0.32 to 3.03 t ha 1 and 1.37–3.69 t ha 1 in rice, and 0.49–1.17 t ha 1 and 0.71–2.26 t ha 1 in wheat across the locations, respectively. Added net return (in US $) from improved practices over FFP and SR under RWS ranged from 219.6 to 804.9 and from 104.3 to 599 ha 1, respectively. Compared to improved practices, PFPN under SR and FFP were lower by 18.9 and 38.3% in rice, and 18.5 and 39.5% in wheat, respectively. Omission of P and K from improved nutrient management schedule resulted in yield loss of 0.6–2.8 t ha 1 in rice, and 0.43–1.84 t ha 1 in wheat, respectively. The annual removal of native P and K in the respective omission plots ranged from 21.8 to 46.1 kg P ha 1 and from 158.4 to 349.1 kg K ha 1. Application of 26 kg P and 99 kg K ha 1 under improved practices had synergistic effect on nutrient use efficiencies viz. PFPN, AEP, AEK, REP and REK. Results suggested that optimised nutrient supplies considering crop nutrient needs and INS have potential for improving yields, nutrient use efficiency and profits in RWS. The improved nutrient management strategy used in this study could be used in larger domains for improving cereal productivity, nutrient use efficiency and farm profits.Not Availabl

Applying deeper learning and Confucian values in enhancing school effectiveness: Empirical results and findings

[[abstract]]The study investigates how school teachers' personal background influences their deeper learning capacity and the school effectiveness. Furthermore, the study examines the correlation between teachers' learning capacity and school effectiveness. Four sets of analyses are performed: t tests, one-way ANOVAs, Pearson correlations, and stepwise regression analyses. The research targets a single top-ranking urban junior high school that has the highest admission rates for senior high schools in Taiwan. Data were collected from 192 school teachers, drawn from various grade levels. Results show that (a) personal background does affect teachers' deeper learning capacity and school effectiveness and (b) deeper learning capacity has a strong correlation with school effectiveness.[[journaltype]]國外[[incitationindex]]SSCI[[booktype]]紙本[[countrycodes]]US
