Pathogenic microorganisms are able to adhere on equipment surfaces, being possible to contaminate food during processing. Salmonella spp. and Listeria monocytogenes are important pathogens that can be transmitted by food, causing severe foodborne diseases. Most surfaces of food processing industry are made of stainless steel joined by welds. However currently, there are few studies evaluating t...

Tigecycline (TIG), the first member of glycylcycline bacteriostatic agents, has been approved to treat complicated infections in the clinic because of its expanded-spectrum antibiotic potential. Recently, an increasing number of studies have emphasized the anti-tumor effects of TIG. The inhibitory effects of TIG on cancer depend on several activating signaling pathways and abnormal mitochondria...

Test Instance Generators (TIG’s) are important to evaluate heuristic procedures for NP -hard problems. We analyze a TIG in use for the TSP. This TIG, due to Pilcher and Rardin, is based on a random cut method. We show that it generates a class of instances of intermediate complexity: not as hard as the entire TSP class unless NP = co(NP ); not as easy as P unless NP = P . Since the upper bound ...

This study sought to characterize aluminum nanocomposite wires that were fabricated through a cold-rolling process, having potential applications in TIG (tungsten inert gas) welding of aluminum. A206 (Al-4.5Cu-0.25Mg) master nanocomposites with 5 wt % γAl₂O₃ nanoparticles were first manufactured through a hybrid process combining semi-solid mixing and ultrasonic processing. A206/1 wt % γAl₂O₃ n...

Resistance spot welding process comprises of electric, thermal and mechanical phenomenon, which makes this process complex and highly non-linear and thus, it becomes difficult to model it. In order to obtain good weld nugget during spot welding, hit and trial welds are usually done which is very costly. Therefore the numerical simulation research has been conducted to understand the whole proce...

Automobile bodies made by mix of steel and aluminum composites are getting famous in present days to decrease weight. Present work means exhibit the strength Aluminum welded joint. Primary measures centered this forecast, streamlining welding measure boundaries investigation intermetallics. Base materials utilized AA6061 alloys SS304 hardened alloy. BCuP-4 copper filler bar is for TIG welding/b...
