The morphology of the canine cardiac myosin molecule has been investigated in the electron microscope with Hall's mica-replica technique. The molecule is an elongated rod (shaft) of nonuniform diameter with a globular expansion (head) on one end. Statistical analysis of the lengths of 1908 molecules showed that the mean length was 1610 +/- 250 A; the mean length of the head was 210 +/- 20 A; an...

abstract in order to evaluate the effects of drought stress and defoliation on sunflower, a study was conducted under controlled conditions. treatments were a combination of three levels of drought ((100, 60 and 30 percent of field capacity (fc)) and three levels of defoliation (control, removal of either 4 or 6 leaves from lower part of the plant) laid out, in a completely randomized design wi...

this paper is about experimental results for partial reduction of vortex at vertical pipe intakes. one of the easiest and practical ways of reducing vortex effect is to use anti-vortex plates or baffles. these plates can be used to avoid the vortex completely or partially. this paper will concentrate on the latter case. rectangular plates with different dimensions have been placed at different ...

PURPOSE This study investigated the shape of bone grafts and associations with upper limb function over the long term after free vascularized fibular head graft (FVFHG) for reconstruction of the proximal humerus after wide resection for bone sarcoma. METHODS Patients comprised 3 women who had undergone FVFHG at least 5 years previously. Age at surgery was 12 years in 2 cases and 76 years in o...

This aim of this paper is to investigate the specific absorption rate (SAR) distribution in a human head by using the finite-difference time-domain (FDTD) calculations, due to exposure to EMF radiation from a mobile phone at frequencies 900 MHz Mobile Phone model with a λ/2 monopole antenna and a hand head phone model dimensions are 100 mm x 50 mm x 20 mm. The head model used is a sphere with a...

The need for electrical energy in Nehibe village is currently increasing along with the increase population and new households. demand electricity this reaches 18 kW, an average power per household of 450 VA. problem that Hachakwa Micro Hydro Power Plant (PLTMH), which very close to village, has a capacity only 10 kW. Based on problem, study aims design peltor turbine two nozzles 26 kW PLTMH. T...

Abstract A non-linear finite element technique is used to study the progressive forming process of sheet, and elastic-plastic distribution analyzed based on Abaqus/Explict. Finite simulations with different parameters were carried out analyse effects tool head diameter, layer feed sheet properties quality. The results show that increasing diameter or decreasing will result in better quality, in...

in order to study the qualitative and quantitative yield and some agronomic characteristics of sunflower (helianthus annus l.) in response to seed inoculation with pgpr under various levels of nitrogen fertilizer, a factorial experiment was conducted based on a randomized complete block design with three replications in field experimental university of mohaghegh ardabili during growing season o...

to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...
