in the present work a two dimensional numerical investigation of steam flows in a turbine blade passage is performed. a finite volume approach has been used and the pressure–velocity coupling is resolved using the simple algorithm. the purpose of this paper is to find that one of the used turbulent models is better for this kind of studies. a structured mesh arrangement with boundary layer mesh...

[1] Phytoplankton alter the absorption of solar radiation, affecting upper ocean temperature and circulation. These changes, in turn, influence the atmosphere through modification of the sea surface temperature (SST). To investigate the effects of the present-day phytoplankton concentration on the atmosphere, an atmospheric general circulation model was forced by SST changes due to phytoplankto...

This paper presents the reverse hinge spoiler, a novel spoiler concept, for flight load control. The is control surface mounted on upper of wing. Unlike conventional hinged spoilers that are at their front and rotate forward toward leading edge wing, proposed concept its rear rotates backward trailing aerodynamic performance compared contrasted with different conditions locations using two-dime...

Using a data sample of 980 fb$^{-1}$ collected with the Belle detector at KEKB asymmetric-energy $e^+e^-$ collider, we study for first time singly Cabibbo-suppressed decays $\Omega^0_c\to\Xi^{-}\pi^{+}$ and $\Omega^-K^+$ doubly decay $\Omega^0_c\to \Xi^- K^{+}$. Evidence an $\Omega^0_c$ signal in $\Omega^0_c\to\Xi^-\pi^+$ mode is reported significance $4.5\sigma$ including systematic uncertaint...

(SST) products currently available from the series of (Advanced) Along Track Scanning Radiometers, or (A)ATSRs, are found have small biases on regional scales (typically up to 0.3 K) and excellent error statistics in validation (~0.25 K or better). Long-term stability is at present poorly characterized. Work towards " version 3 " SSTs is under way within a project called (A)RC: (A)ATSR Re-analy...

The K(+) M-current (I(M), Kv7) is an important regulator of cortical excitability, and mutations in these channels cause a seizure disorder in humans. The neuropeptide somatostatin (SST), which has antiepileptic properties, augments I(M) in hippocampal CA1 pyramidal neurons. We used SST receptor knock-out mice and subtype-selective ligands to investigate the receptor subtype that couples to I(M...

مداخل يعسوت رامعم ميمصت " ةجاحلا بسح ةددعتم طئاسو " ABSTRACT in this paper we develop a Vhdlbased scalable architecture of a multimedia on demand server model. Te three server subsystems are:the control subsystem, the communication subsystem and the storage subsystem are modeled. The communication subsystem is designed as an interconnection network with meshed-pipe structure and delivers packe...

This study uses measurements of radiation and cloud properties taken between January and August 1998 by three Tropical Rainfall Measuring Mission (TRMM) instruments, the Clouds and the Earth’s Radiant Energy System (CERES) scanner, the TRMM Microwave Imager (TMI), and the Visible and InfraRed Scanner (VIRS), to evaluate the variations of tropical deep convective systems (DCS) with sea surface t...
