The austenitic stainless steel was coated by dipping into a molten Al-12.4%Si alloy at 765oC. The effect of immersion times in the range of 60 to 900 s was investigated with respect to the phase nature, thickness, and microhardness. An uniform layer (~12 m) of Al12(Fe,Cr)3Si2 intermetallic with hexagonal crystalline structure is formed, irrespectively the immersion time. Microhardness of the c...

In a pilot study two patients with brittle asthma and two with morning dipping received terbutaline or a placebo administered subcutaneously either by continuous infusion or in injections every six hours. In two patients brittle asthma was completely suppressed by terbutaline 1 mg/day given by either method. In the two others early morning dipping responded only to continuous subcutaneous infus...

Control While many intervention techniques have been developed and applied with varying degrees of success, it remains clear that a comprehensive method for tick control still needs to be realised, especially for resource­constrained farmers. Conventional methods involve the use of commercial acaricides under intense dipping program­ mes. In Zimbabwe, the Department of Veterinary Services (DVS)...

1) An accretionary prism with a constant width of approximately 75 km does exist; 2) The morphology of this prism varies rapidly along the arc and is linked, firstly to the morphology and structure of the upper part of the dipping plate and, secondly to the presence of volcanic island acting as sediment sources; The island arc and its connecting structural features such as troughs at the rear o...

in 2012 august 11 (12:23 utc) a moderate earthquake with mw=6.4 (usgs) occurred between ahar and varzaghan towns in azarbayjan province at northwest of iran. after eleven minutes another earthquake shook the area with mw=6.2 (usgs). these consecutive earthquakes followed by intensive sequences of aftershocks whereas the strongest one had mw=5.3 (usgs). in data processing including depth modific...
