injecting local anesthetic at the seeking current would be appealing.it would save time and avoid potentially dangerous manipulations of the needle. this study aimed to test the hypotheses that in vertical infraclavicular block, injecting local anesthetic at a seeking current of 0.8 ma would produce the same quality of block as injecting at ≤0.5ma. a total of sixty asa i -iii adult patients sch...

hiv infection by maternal transmission is increasing in the world due to the increase in infected women who are not receiving appropriate antiretroviral therapy. prognosis of hiv infection in children is poor because the newborn has an immature immune system. early diagnosis and therapy are needed to avoid the development of aids. new therapies are becoming available but prevention of infection...

purpose: compaison of excyclotorsion induced by horizontal transposition of vertical rectus muscles versus vertical transposition of horizontal rectus muscles in rabbit eyes. methods: in this exprimental study, group 1 underwent full tendon nasal transposition of the superior rectus and full tendon temporal transposition of the inferior rectus (10 adult rabbits); group 2 underwent superior tran...

The water percolation loss beyond root zone in the soil is one of the important parameters to determine water requirement of rice plant. If the amount of water percolation rate into the soil is estimated more carefully, determination of water requirement will be evaluated better and designing for system of irrigation, drainage and related establishments will be more easily done. The purpose of ...

damages due to northridge and kobe earthquakes were expressive of considerable effects of vertical components of earthquakes compared to the horizontal ones. on the other hand, thin steel plate shear wall is one of the newest resistant systems which until now it`s behavior haven’t been investigated under vertical component of earthquake. therefore, in this article, effects of vertical component...

the purpose of this article is to design a model for measuring productivity in the public sector . to this end both effectiveness and efficiency are considered. the measurement of effectiveness focus on four dimention ; service delivering to client, citizen satisfaction, improvement of society?s conditions and undesired outcomes of service delivery . we used delphi methods to define the effecti...

background & aim: saffron (crocus sativus l.) formerly was important in turkey. saffron cultivation has been decreased and it is now only cultivated in three villages in this country. it is triploid and exclusively propagated in a vegetative way by corms. in turkey, saffron is traditionally planted by placing corms in rows randomly without grading or sorting; which results in placement of c...

The subject of this paper concerns with the bifurcation of limit cycles and invariant cylinders from a global center of a linear differential system in dimension 2n perturbed inside a class of continuous and discontinuous piecewise linear differential systems. Our main results show that at most one limit cycle and at most one invariant cylinder can bifurcate using the expansion of the displacem...
