normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : distraction osteogenesis is an established option for reconstruction of amputated fingers. in contrast to the primary method of distraction osteogenesis, using kirschner wire (k-wire) as an internal fixator is not common today. this study was conducted to evaluate distraction osteogenesis with and without k-wi...
tourism , today as one of the ways to make money, create jobs , and social and political interactions is considered. this paper aims to examine the strengths and weaknesses of tourism development in mahmoud abad ( mazandaran ). the research method in this study is " descriptive - analytical " and to collection of data used field methods such as questionnaires and documentation - library. the sa...
in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
In this paper we study External A*, a variant of the internal A* algorithm that employs external memory. The approach applies to implicit, undirected, unweighted state space problem graphs with consistent estimates. The complexity of the External algorithm is almost linear in external sorting time and accumulates to O(sort(|E|) + scan(|V |)) I/Os, where V and E are the set of nodes and edges in...
some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
background with the growing interest in long bone distraction several types of distractors have been introduced; all have the same principle of an outer structure which acts like a scaffold and the distracting mechanism is a separate device which is mounted on this outer structure. objectives we have used a simple and very light weight external fixator we designed and discuss the results of dis...
the entanglement at zero-temperature is studied in a two-qubit xz spin-1/2 chain model in anexternal magnetic field which is applied in the z direction. we have obtained an analytical relation forthe effect of the external magnetic field on the concurrence. it is shown that the ground state of thesystem depends on the strength of exchange coupling. we have shown that the analytical relation oft...
the study compared economic efficiency among smallholder farmers who practiced low external input technology [leit] and high external input technology [heit] agriculture in a harsh macroeconomic environment typified by inadequate fertilizer subsidy in imo state, nigeria. cross sectional data generated from 160 smallholder farmers randomly selected from 2 out of the 3 agricultural zones in imo s...
the teratogenicity of cadmium exposure was studied in virgin nimri rats aged 10-13 weeks. pregnant animals were fed cadmium sulfate equivalent to doses of 1,4 and 7 mg/kg/day of cadmium by oral gavage on the day 7 of gestation. on the day 18 of gestation, fetuses were delivered and examined for external and skeletal malformations. total percent of malformed fetuses in rats treated by different ...
