Resistance spot welding (RSW) as a predominant welding technique used for joining steels in automotive applications needs to be studied carefully in order to improve the mechanical properties of the spot welds. The objectives of the present work are to characterize the resistance spot weldment of DP600 sheet steels. The mechanical properties of the welded joints were evaluated using tensile-she...

The magnetically assisted resistance spot welding (MA-RSW) method provides a promising approach for improving weld performance. However, the MA-RSW process involves complex multiphysics fields that make numerical modeling very challenging. Thus, most (RSW) models adopt electrothermal-mechanical coupling and ignore influence of fluid flows caused by electromagnetic forces on nugget growth. In th...

Nearly all discussions about the appropriate consumption discount rate for climate-change policy evaluation assume that a single discount rate concept applies. We argue that two distinct concepts and associated rates apply. We distinguish a social-welfare-equivalent discount rate (rSW) appropriate for determining whether a given policy would augment social welfare (according to a postulated soc...

The Reduced Surface Wave (RSW) antenna is a relatively new class of microstrip patch antenna. An RSW antenna has the ability to drastically reduce both surface and lateral wave radiation, which leads to an increase in antenna efficiency, a reduction in mutual coupling, and a reduction of edge diffraction and scattering. One specific type of antenna displaying RSW characteristics is the Shorted ...

Under acute stress conditions in the rat, there is rapid and transient increase in circulating prolactin (PRL). This leads to an elevated expression of the long form of PRLR (PRLR-L) first in the hypothalamus and the choroid plexus. This increase in PRL is involved in the inhibition of stress-induced hypocalcemia and gastric erosion. In this study we used rat PRL and a PRLR morpholino-antisense...

At the last few years, multimedia communication has been developed and improved rapidly in order to enable users to communicate between each other over the internet. Generally, multimedia communication consists of audio and video communication. However, this research concentrates on audio conferencing only. The audio translation between protocols is a very critical issue, because it solves the ...

Ensiled rice straw using, water (RSW), molasses plus urea, and whey (RWh) were implied to investigate the ensiling processing on palatability nutritional value of compared untreated (URS). Using resulted in a significant (P < .05) progress fermentation coefficient, Flieg Score others. Protein water-soluble carbohydrates content increased RWh RMU. Gas cumulative with ERS incubation URS. In-vitro...

Voice over IP (VoIP) is a technology to transport media over IP networks such as the Internet. VoIP has the capability of connecting people over packet switched networks instead of traditional circuit switched networks. Recently, the InterAsterisk Exchange Protocol (IAX) has emerged as a new VoIP which is gaining popularity among VoIP products. IAX is known for its simplicity, NAT-friendliness,...

Field evaluation of various biopesticides viz., Beauveria bassiana, Isaria fumosorosea NBAIR pfu-5, Metarhizium anisopliae, Lecanicillium lecanii, azadirachtin and soapnut powder were carried out against coconut invasive Rugose Spiraling Whitefly (RSW), Aleurodicus rugioperculetus Martin at Ramachandrapuram Ambajipeta (Dr BR Ambedkar Konaseema district, AP) during 2020-21 2021-22. Pooled data a...
