We report on the exchange of orbital angular momentum between an electromagnetic microwave and a macroscopic object. Using a quadrupole wire antenna at frequency f = 870 MHz, we induce a torque on a suspended copper strip. The induced torque on the strip is of the order of 10 Nm. A linear dependence of the acceleration of the strip on the radiated power, up to 8.10 °/s2, is observed and rotatio...

this study was conducted to evaluatethe effects of different inter- and intra-row spacing on the dry matter accumulation and partitioning coefficients in faba bean, barakat cultivar. experiment was conducted as factorial in a randomized complete block design with three replications. factors were inter-row spacing (15, 30, 45 and 60 cm) and intra-row spacing (5, 10 and 15 cm). the plant dry matt...

intercropping is one of the management methods for crop production and leads to improvement of resource absorption and use by plants. based on this purpose the present field study was conducted to evaluate radiation absorption and uses efficiency in corn and bean strip intercropping at the farm of the faculty of agriculture, ferdowsi university of mashhad, iran during 2009. the experiment was s...

Introduction: To evaluate, if targeted strip biopsies decrease trauma/pain perception while maintaining diagnostic accuracy in patients with the diagnosis of high-grade squamous intraepithelial lesions of the uterine cervix. Patients and Methods: Between July 1st and December 31st 2014 we performed colposcopically directed strip biopsies in 102 patients with colposcopic suspicion of high-grade ...

Vegetative buffers have shown promising results in reducing runoff volume, sediment, nutrients, and manure-borne contaminants from agricultural fields. Although these vegetative buffer systems been extensively tested field plot-scale studies that utilize either natural or simulated rainfall, of such under highly controlled conditions the laboratory limited. Here, we present development a new sy...

It is shown that for any positive E the strip-packing problem, i.e. the problem of packing a given list of rectangles into a strip of width 1 and minimum height. can be solled within I c 2: times the optimal height, in linear time, if the heights and widths of these rectangles are all bounded below by an absolute constant 2 >O. @ 1998 Elsevicr Science B.V.

BACKGROUND & OBJECTIVES Reusable biostrip consisting enzymes immobilized onto alkylamine glass beads affixed on plasticized PVC strip for determination of triglyceride (TG) suffers from high cost of beads and their detachments during washings for reuse, leading to loss of activity. The purpose of this study was to develop a cheaper and stable biostrip for investigation of TG levels in serum. ...

We consider the 3-staged Strip Packing Problem, in which rectangular items have to be arranged onto a rectangular strip of fixed width, such that the items can be obtained by three stages of guillotine cuts while the required strip height is to be minimized. We propose a new logic-based Benders decomposition with two kinds of Benders cuts and compare it with a compact integer linear programming...

Cold rolling of steel is one of the most important metal forming processes so an accurate control of its parameters during the process is necessary. In this paper, the friction coefficient has been proposed as a function of cold rolling parameters such as forward slip, forward and backward tensile stresses ,strip thickness, static deformation, resistance of strip before and after rolling ,strip...
