The functional properties of a plant can link the plant physiology with community and ecosystem processes. Thus it provides an appropriate tool for investigation of environmental changes and biodiversity. For this purpose, Zeiar rangeland of Damavand Mountain were selected as the 6000ha study area. A stratified-random sampling method was used for the sampling of vegetation and soil. Topograph...
Brown Swiss-Hereford (BS-H) reciprocal cross embryos were transferred to BS and H recipient cows and Red Poll-Angus (RP-A) reciprocal cross embryos were transferred to RP and A recipient cows to estimate the relative contributions of ovum cytoplasm and uterine influences to prenatal maternal effects. Calves resulting from embryo transfers (ET) were weaned early (3 to 5 d). Reciprocal cross mati...
motor unit number estimation in normal and parkinsonism model of medial gastrocnemius muscle in rats
motor units (mus) reflect the function of the central nervous motor system. thus, the estimated mu number is a good option to investigate the functional movement disorder in the parkinson’s disease (pd). the purpose of this study was to compare the estimated mus number in the medial gastrocnemius (mg) muscle of the normal rats and those with the parkinsonism. the mg muscle of two age-matched gr...
Manual opacity transfer function editing for volume rendering can be a difficult and counter-intuitive process. This paper proposes a logarithmically scaled editor, and argues that such a scale relates the height of the transfer function to the rendered intensity of a region of particular density in the volume almost directly, resulting in much improved, simpler manual transfer function editing.
A mathematical model of a continuous reheating furnace has been developed to identify the design and operating parameters that significantly affect furnace performance. In this study, the furnace is modeled 3 dimensionally and theMonte Carlomethod is used to find the overall absorption factor. The overall absorption factor is then used to calculate the energy balance for furnace walls, the gas,...
According to general relativity theory (GRT), the clock at a position with lower geopotential ticks slower than an identical one higher geopotential. Here, we provide comparison using non-transportable hydrogen and transportable for altitude transmission based on two-way satellite time frequency transfer (TWSTFT) technique. First, set fifth floor another ground floor, their height difference of...
tea is very important product in many countries due to huge consumption in the world and its valuable contains. the traditional harvesting method needs to be improved due to its effect on yield and quality. mechanical plucking as a substitution to conventional method is spreading quickly and is necessary to be investigated for proper adoption. one of crucial factor has been noted to be the heig...
New pressure drop / flow rate measurements coupled with a previously reported heat transfer database have resulted in new friction factor and heat transfer correlation equations for fan-driven impinging flow through square arrays of cylindrical cross-section pin-fins. The correlation equations include the effect of coolant flow rate, pin-fin density and pinfin height. A comparison with a simila...
