Background & Aims: Disorders caused by iodine, with a wide spectrum of clinical manifestations are among the main health - nutritional issues of our community and health priorities. Kerman province was one of the areas with high prevalence of endemic goiter before iodination programs. Since control and monitoring of programs of iodine deficiency elimination in our country is done every 5 years,...

The impact of major I/O system parameters 011 the performance of RAID-5 disk arlrzy systems is described in this paper. It is shown that the system throughput is a nonlinear function of the uumber of disks per rank, number of ranks in the system, compounded data rate of SCSIs installed between a host and a controller, the size of a controller buffer, the way files are striped across individual ...

A recent queueing-based modelling methodology of RAID systems compared the mean disk access times of the two most common variants, RAID0-1 and RAID5, as well as a multi-RAID system in which they coexist. Accesses to multiple disks occur concurrently for each logical (user) request and complete only when every disk involved has completed. The models therefore needed to estimate the mean value of...

In this work, we compare the two approximations of a pathconnected space X, by the Ganea spaces Gn(X) and by the realizations ‖Λ•X‖n of the truncated simplicial resolutions emerging from the loop-suspension cotriple ΣΩ. For a simply connected space X, we construct maps ‖Λ•X‖n−1 → Gn(X) → ‖Λ•X‖n over X, up to homotopy. In the case n = 2, we prove the existence of a map G2(X) → ‖Λ•X‖1 over X (up ...

Individuals investing in a Venture Capital Trust IPO listed on the London Stock Exchange receive a number of conditional tax incentives; the time related nature of the conditions can create a “lock in effect”. By deriving a dynamic model of the value of these incentives we examine how they influence investors’ pricing and trading decisions. This contributes to the ongoing tax capitalisation deb...

We determine, in two independent ways, the number of BPS quantum states arising from supergravity degrees of freedom in a system with fixed total D4D0 charge. First, we count states generated by quantizing the spacetime degrees of freedom of “entropyless” multicentered solutions consisting of D0-branes bound to a D6D6 pair. Second, we determine the number of free supergravity excitations of the...

Saline playas in north-western Nevada, U.S.A., remnants of pluvial periods of the Pleistocene, represent a tremendous source of unconsolidated sediments available for aeolian transport. This study investigated the transport of aqueous-soluble solutes in dust from July 1994 through June 1996 along a transect from a barren salt-encrusted playa surface (elevation"1224 m), to a former pluvial lake ...

Most existing formal models of goals [2, 3] assume that all goals are equally important and many only deal with achievement goals. Moreover, they do not guarantee that an agent’s goals will properly evolve when an action/event occurs, e.g. when the agent’s beliefs/knowledge changes or a goal is adopted or dropped. Also, most of these frameworks do not model the dependencies between goals and th...
