Dapsone first came into medicine as an antibacterial agent but was found to be less effective than other sulfonamides. Likewise its activity against tuberculosis was disappointing. Nevertheless, it has been the main stay in the treatment of leprosy. It also has some action against malaria and other parasites. Nowadays, after leprosy, dapsone has proved as a valuable drug in the treatment of a w...

torsion and infarction of the greater omentum are two rare clinical situations which present as an acute abdomen. nevertheless, knowledge concerning these two problems can help the surgeon in proper diagnosis and treatment. since the first report on primary torsion by eitel in 1899, a few hundred more have been reported and some collective reviews published to date. in this study we will presen...

background: chromosomal disorders are the most common cause of first trimester spontaneous abortion. among the human chromosomes, chromosome no.9 was the most common structural chromosomal variant and it is not thought to be of any functional importance, which often considers as a normal variation in structural polymorphisms, nevertheless there are some studies which claim that there is an asso...

The problem of pole assignment, also known as an eigenvalue assignment, in linear discrete-time periodic systems in discs was solved by a novel method which employs elementary similarity operations. The former methods tried to assign the points inside the unit circle while preserving the stability of the discrete time periodic system. Nevertheless, now we can obtain the location of eigenvalues ...

The number of lambs sold per ewe mated in the breeding flock has a considerable impact on sheep operation profitability. This depends primarily on fertility, prolificacy (# of lambs), and lamb survival, mothering ability, milk production of the ewe and lamb growth rate. Optimal reproduction does vary by environment and management system – some sheep operations don’t want a lambing rate over 200...

The structural differences between  dormant and nondormant seeds of wild oats (Avena ludoviciana Durieu) were studied by light and transmission electron microscopy. Radial elongation of  scutellum epithelial cells were observed in nondormant seeds after imbibition, compared with dormant seeds in which cells were completely compressed. Ultrastructural differences for example, dilution of cytopla...

Adjustable throat-area expansion valves (ATAEV) are functioned as area regulator control units. In literatures, there are many expansion valves normally used in automotive air-conditioning systems, as regulator and electrical type valves. Nevertheless, a review study for such issue has not been introduced, according to the best of author knowledge. The present paper presents a review study for ...

We call a local vector lattice any vector lattice with a distinguished positive strong unit and having exactly one maximal ideal (its radical). We provide a short study of local vector lattices. In this regards, some characterizations of local vector lattices are given. For instance, we prove that a vector lattice with a distinguished strong unit is local if and only if it is clean with non no-...
