In this study, the heat transfer and flow characteristics for cube circular hollow models in channels with cross flow-impinging jet were numerically investigated by using water 2% CuO-Water nanofluid. The numerical work was carried out steady three-dimensional Ansys-Fluent program k-? turbulence model. A fin 45? 90? angles D, 1.166D, 1.333D (K) lengths added to upper channel surface from imping...

The study analyses the dynamics in area, production and productivity of coffee India. It was analyzed using trend analysis, instability analysis decomposition analysis. time period chosen for 1961 to 2020. years were divided into three periods namely pre-liberalization (1961-1989), post-liberalization (1990-2020) based on liberalization market. results showed that area under increased from 1150...

A 9-year-old girl presented with fever for 4 days. On day 8 of illness, when her fever subsided, she developed hypotension. Her platelet count dropped to 15000/ml and hematocrit increased to 42.8%. She was resuscitated with fluid boluses. She developed typical dengue rash of convalescence 3 days after defervescence (Fig. 2). Her dengue serology IgM and IgG were positive, suggestive of secondary...

ABSTRACT We present a spatially resolved spectroscopic study for the metal poor H ii galaxy J084220+115000 using MEGARA Integral Field Unit observations at Gran Telescopio Canarias. estimated gas metallicity direct method oxygen, nitrogen, and helium found mean value of 12 + log (O/H) = 8.03 ± 0.06, integrated electron density temperature ∼161 cm−3 ∼15400 K, respectively. The distribution shows...

iSCSI is a network storage technology designed to provide an economical solution over a TCP/IP Network. This paper presents a new iSCSI design with multiple TCP/IP connections. The prototype is developed and experiments are conducted for performance evaluation on Gigabit Ethernet (GE). Test results show that the new iSCSI design improves performance 20%~60% compared with normal iSCSI architectu...

the order hymenoptera with more than 115000 described species, includes over 10% of species diversity in the world. these insects are one of the most important groups in economic and ecological terms. vespidae family plays an important role in biological control of some insect pests. this family includes six subfamilies and almost 4150 known species in the world( carpenter,1982 ). these insects...

It has been estimated that approximately 15000 to 20000 hours are required to train a surgeon.1 However, several time-constrains imposed globally2 have significantly reduced training time in the Operating Room (OR) posing a significant challenge for surgical educators and creating an impetus for the development of new educational methods.3 Since August 2005, all medical graduates in the United ...
