in iran, cheyletid mites (acariformes: cheyletidae) were collected over 15 years (1996–2010) in stored cereal. samples were collected from silos, flour-mills, barn and rice-mills in 12 provinces scattered throughout the north,  centre, east and west of iran. 8 genera and 13 species were recorded: acaropsellina sollers (kuzin, 1940), cheletomorpha lepidopterorum (show, 1794), cheyletus bidentatu...

Due to their functionality, stored value purses based on smart card technology are prominent candidates for being the dominant medium of exchange for micropayments. However, the overall prospects of these payment systems are yet ambiguous, both from the perspective of practice and monetary theory, because their potential to substitute for cash is still largely unknown. As a contribution to the ...

The use of ion-storage rings is discussed for studies of nuclear reactions and structure, with emphasis on energetic beams of short-lived, radioactive nuclei. Aspects of internal versus external luminosity are considered as well as other issues connected with the inverse kinematics of reactions induced by a circulating beam of complex nuclei. Some of the physics motivation that is driving studi...

Stored-product insects can cause postharvest losses, estimated from up to 9% in developed countries to 20% or more in developing countries. There is much interest in alternatives to conventional insecticides for controlling stored-product insects because of insecticide loss due to regulatory action and insect resistance, and because of increasing consumer demand for product that is free of inse...

We solve the Vlasov equation for the longitudinal distribution function and find stationary wave patterns when the distribution in the energy error is Maxwellian. In the long wavelength limit a stability criterion for linear waves has been obtained and a Korteweg-de VriesBurgers equation for the relevant hydrodynamic quantities has been derived. Paper presented at Workshop on Instabilities of H...

We study the problem of using proxy servers to stream video stored at a geographically separate location. The separation of the server and the storage introduces a nonnegligible delay in retrieving video frames in real time. To ensure network stability, we use an additive-increase and multiplicative-decrease transport protocol to support the streaming process. We develop an effective scheme to ...

BACKGROUND Traditionally, for DNA analyses, DNA is recovered from buffy coats. Since DNA in urine has been reported to deteriorate quickly, this option is often not considered. To complete our DNA database in patients with ANCA-associated vasculitis, we aimed to extract DNA from stored urine. METHODS Urine was stored at the time of kidney biopsy from patients included in our regional kidney b...

The increasing occurrence of allergies in the developed countries and greater interest in food safety has drawn attention to the presence of allergens in agro products during storage. Stored agro products can contain allergenic contaminants of plant, microbial, or animal origin. Several stored-product insect and mite species were confirmed as sources of allergens. The most important are storage...

Roselle calyces are rich in nutrient, but the utilization of its calyces in the preparation of jam is not popular in Africa. The quality attributes of stored Roselle jam from dark and light red varieties were investigated. Roselle jam was processed using the open kettle method. The processed jams were stored at ambient and cold temperatures. At two weeks interval they were evaluated for pH, tit...
