The probable reasons for evolution of weld porosity and solidification cracking and the structure- property relationship in aluminium welds were investigated. Aluminium plates (1xxx series) were welded by Tungsten Inert Gas (TIG) welding process, 5356 filler metal was used and heat input was controlled by varying welding current (145A, 175A and 195A). The welded samples were examined under opti...

A protein called P36 holds the key to how different species of malaria parasite invade liver cells.

Title of dissertation: FLEX CRACKING AND TEMPERATUREHUMIDITY-BIAS EFFECTS ON RELIABILITY OF MULTILAYER CERAMIC CAPACITORS Mohammadreza Keimasi, Doctor of Philosophy, 2007 Dissertation directed by: Professor Michael Pecht Department of Mechanical Engineering Multilayer ceramic capacitors (MLCCs) are known to be susceptible to cracking when subjected to excessive printed circuit board (PCB) flexu...

Although solidification cracking is not usually regarded as a serious problem when welding ferritic steels, improvements in the submerged arc welding process, using higher deposition rates and faster welding speeds, have led to welding conditions more likely to give cracking. Furthermore, the need to weld stronger tougher steels, where the inspection requirements are more stringent, has led to ...

Password plays an important role in online authentication. But it suffer from two interactable problems ,one is password cracking and second is password theft. Password agent mechanism contains strong hashing scheme which provides stronger protection against password theft and password cracking. Password Agent generates strong passwords by enhancing the hash function with a large random salt. T...

A fractured nutcracker was examined for determining the root cause/s for premature fracture/failure. This is one of the common tools used typically for cracking hard nuts. In this study, metallurgical failure analysis techniques namely, visual inspection, optical microscopy, SEM, and hardness tests were used in investigating the broken product. From the metallurgical analysis, it was determined...

The thermal cracking of hydrocarbons for olefin production is carried out in long tubular reactors inserted in a furnace, in this process the heat flux along the reactor wall determines the feedstock conversion, the olefin selectivity's and rate of coke deposition. A detailed firebox simulation model is therefore a powerful tool in the design and operation of pyrolysis furnaces and reactors to ...

Sweet lime split bark is a disorder of increasing importance in Fars province. Previously we showed that a new variant of hop stunt viroid (HSVd-sb) was related to the disorder. It had homology with a noncachexia variant of hop stunt viroid (CVd-IIa-117) which causes cracking the bark of trifoliate orange rootstocks. In this study, showed that M.NgoBIX, BglI and BsrI restriction enzymes can c...
