BACKGROUND South Pars special economic energy zone is the world's second largest gas reservoir that was established two decades ago. High incidence of social harms is observed in this region due to various problems such as drug addiction which is of high prevalence. OBJECTIVES The current study aimed at finding the strategies to prevent drug abuse and formulating policies in the region. MAT...

This paper gives the results of an investigation into the effects of wing torsion in a ternary-type spring-tab flutter. The results presented are for a series of calculations on an idealised system having degrees of freedom in wing pitch, rotation of the control surface and rotation of the tab; the pitching degree of freedom is spring restrained and is intended to represent wing torsion. The ta...

This is an experimental comparison Of two axi-symmetric, isentropic plug nozzles. In one of these (Model No. 1) the afterbody is cylindricaland a secondary flow is bled into the annular base. The other (Model No. 2) has a parabolic afterbody with no base or bleed. In both cases the expansion is all-external and the design pressure ratio is 14. These models were tested over a range of primary an...

A piloted simulation study of the handling characteristics of the B.A.C. 221 aircraft in the approach configuration was made in preparation for the first flight of the aircraft. The simulation included a simpli~ed representation of the outside visual world, and cockpit motion in pitch and roll. Values of the aircraft's lateral derivatives and moments of inertia were varied to allow for uncertai...

Temperatures and pressures have been measured in the shock-heated gas upstream of the nozzle of a reflected-shock hypersonic tunnel. Temperatures were measured by spectrum-line reversal, using sodium D lines for some measurements and the blue resonance lines of chromium for others. The temperature and pressure measurements immediately behind the first reflected-shock wave agreed well with theor...

The working paper publication series is designed to provide users with timely research results while refinements and longer term synthesis are completed, and final reports are available. The preparation of working papers and their discussion with those who design and influence programs and policies in Mozambique is an important step in the Directorates's overall analysis and planning mission. C...

We present results of two large scale comparative studies of the genomic basis of resistance of Interior spruce to the white pine weevil. Both volume growth, the main objective of the spruce breeding program in British Columbia, and white pine weevil resistance, are examined. “Interior spruce” is a species complex involving mainly Picea glauca (White spruce) but introgressed with P. engelmannii...

The aim of this study is to analyze eventual differences in characteristic of suicide between two areas of the Republic of Croatia, mediterranean and continental, according to the following variables: suicidal rates, season, month, day, method, places, socioeconomic variables such as gender, ages, marital status, employment, education, and psychiatric or medical characteristic. Data were collec...

An infeasible interior-point algorithm for solving the$P_*$-matrix linear complementarity problem based on a kernelfunction with trigonometric barrier term is analyzed. Each (main)iteration of the algorithm consists of a feasibility step andseveral centrality steps, whose feasibility step is induced by atrigonometric kernel function. The complexity result coincides withthe best result for infea...
