Development of autonomous underwater vehicles (AUVs) which meets the design constraints and provides the best hydrodynamic performance is really an important challenge in the field of hydrodynamics. In this paper a new profile is used for designing the hull of AUVs. The nose and tail profiles of an AUV using presented profile is designed such that it can properly consider the length constraints...

comment on essays from students in other countries, and — worst of all — provide information for incessant bureaucratic enquiries that should not be taking place at all. Non-compliance is rapidly followed by a further enquiry or a thinly veiled reprimand for being forgetful or hurtful or not attending to emails. It is madness. Is science organised effectively? Science can be pricey and the publ...

An intensive experimental investigation was conducted to study the effect of vertical tail, single and twin (with different cant angles) on the flow field and the corresponding aerodynamic forces and moments of a model of a fighter A/C. Aerodynamic forces under different flight conditions and different vertical tail settings were measured in a supersonic wind tunnel. Furthermore, effects of ver...

objective(s) the present study was undertaken to investigate the nociception activity of promethazine, a tranquillizer devoid of hypnotic activity in mice. materials and methods antinociception was evaluated, using the acetic acid-induced writhing, tail flick, hot plate and formalin pain tests. results promethazine (4 and 6 mg/kg) and acetylsalicylic acid (100 mg/kg) produced a significant inhi...

background: organophosphorus pesticides has been widely used in agriculture fields to control various crop insects and their extensive use pose human life at threat because of their adverse effects on human health. in this study, we checked the effects of gst polymorphism on ameliorative effect of curcumin and carvacrol against dna damages. methods: comet assay was used to assess the dna damage...

background :  the aim of this paper was to study the prevalence and intensity of anisakids lar­vae in the long tail tuna fish captured from iranian shores of persian gulf. methods : different organs including skin, abdominal cavity, stomach and intestinal contents, stom­ach sub serous tissues, liver, spleen, gonads and 20 grams of muscles of 100 long tail tuna fish ( thannus tonggol ) caught fr...
