The three armoured SS Sonderverbände (special units) Leibstandarte, Das Reich and Totenkopf which constituted the II Panzer Korps played a key role during battle of Kursk (5.7–23.8.1943), first Operation Citadel (5–16.7.43) then (minus Leibstandarte) defence Kharkov (3–23.8.43). For time, as result recent archival discovery (complete inventories for 20.7.43 1.8.43), this article can give exact ...

ventilation tube (vt) insertion is the most common otologic operations performed in children, which has great importance in recovery and prevention of hearing loss in children with eustachian tube dysfunction in critical ages of growth development. the location of the vt insertion varies in different studies; the differences are in recovery rates and sequelae of vt insertion. this study is perf...

the increasing incidence of systemic candidiasis, which parallels the use of invasive and immunosuppressive medical procedures, necessitates development of rapid and cost effective tests for diagnosis of systemic candidiasis. therefore in this study 85 mice were first immunosuppressed by cyclophosphamide and then infected by candida albicans ncpf 3153. other 85 mice were employed as control. th...

An annotated list of 83 scale insect species (Hemiptera: Sterorrhyncha: Coccoidea) recorded from Saint Lucia is presented, based on data gathered from UK quarantine interceptions, samples collected in an urban coastal habitat in the North West of the Island in 2013, and published records. Thirty-three species (40%) are recorded for the first time for the country, including Dysmicoccus joannesia...

A key factor enabling the achievement of the required capacity by longwall mining systems is to obtain a satisfactory service life for individual components of such systems. Such components include right-angle planetary gearboxes for armoured face conveyors. An increase in the service life of such equipment can be achieved by ensuring adequacy in terms of design, materials and organization. As ...

in this paper, single, bi-layered and three-layered tube hydroforming processes were numerically simulated using the finite element method. it was found that the final bulges heights resulted from the models were in good agreement with the experimental results. three types of modeling were kept with the same geometry, tube material and process parameters to be compared between the obtained hydr...
