Distortion and deformation of tubes during machining operations are very important. In this study, a tube used in magnetic drum separator under concentrated load (machining load) is considered. Using finite element simulation, deformities and their dependence on parameters such as the thickness of the tube and the place of concentrated force are observed and predicted. To compare and confirm th...

Apart from strengthening crew protective capability gunfire, the hull obliquity in a light armoured vehicle (LAV) affects its weight and comfortable occupancy. Thus, it requires critical design analysis for obliqued hull. The study aims to present optimal of an structure ensure occupancy along with minimum attainable higher protection gunfire. Three geometric models (G1, G2, G3) were investigat...

On the battlefield, modern vehicles perform a variety of roles. Transportation is one most fundamental. Operating in different terrains, including urban areas, means exposing crew to hazards. To increase protection, passive and active protection systems are used. other hand, addition support infantry offensive operations an equally important activity. The common solution for medium wheeled mann...

The kiwifruit cultivar Actinidia chinensis 'Hort16A' is resistant to the polyphagous armoured scale insect pest Hemiberlesia lataniae (Hemiptera: Diaspididae). A cDNA microarray consisting of 17,512 unigenes selected from over 132,000 expressed sequence tags (ESTs) was used to measure the transcriptomic profile of the A. chinensis 'Hort16A' canes in response to a controlled infestation of H. la...

In recent years, an undescribed species of Unaspis MacGillivray (Hemiptera: Coccomorpha: Diaspididae) has become a damaging pest on the fruit crop Lansium domesticum Corrêa (family Meliaceae) in the Philippines.

Considerable interest is currently focused on fish haemoglobins in order to identify the structural basis for their diversity of functional behaviour. The armored catfish Liposarcus anisitsi presents accessorial air breathing through a modified stomach, which allows this species to survive in waters with low oxygen content. The analysis of its haemolysate has shown the presence of four main hae...

The auditory sensory system of the taxon Hetrodinae has not been studied previously. Males of the African armoured ground cricket, Acanthoplus longipes (Orthoptera: Tettigoniidae: Hetrodinae) produce a calling song that lasts for minutes and consists of verses with two pulses. About three impulses are in the first pulse and about five impulses are in the second pulse. In contrast, the disturban...
