Characteristic features are: the leaf in T/S shows an epidermis of colourless, thickwalled, non-suberised cells, a band of photosynthetic and vascular tissue around the leaf perimeter (2+3), a central core of large thin-walled cells with contents staining pink-orange with KOH solution; yellow-green stomata and idioblasts containing bundles of calcium oxalate raphides (1), each up to 200μ long, ...

Serial microscopic sections of the left ventricular myocardium were examined in 12 autopsy specimens of hypoplastic left heart syndrome. Multiple ventriculocoronary arterial connections, thickwalled coronary arteries, prominent endocardial fibroelastosis, myofiber disarray and focal calcification/ scarring of the myocardium were noted in the cases with patent left ventricular inflow and obstruc...

the effective factors of forward speed, cylinder rotation, and clearance between a combine’s cylinder and concave on wheat kernel breakage and seed germination were studied in karaj area using a 955 model john dear combine. this study was conducted on three levels of adjustment for each of the variables, 1.2, 1.8 and 2.5 km/hr for forward speed, 800, 900, 1000 rpm for cylinder rotation as well ...

multistage and semi-mechanized harvesting of rice in khouzestan province, iran, causes much loss. depending on available facilities and conditions, either spike-tooth or rasp-bar cylinders are employed with either direct or indirect combine harvesting methods. the present research studied the effect of these different harvesting methods on the amount of losses in two rice varieties in 2001-2002...

an experimental study was carried out on the wake of a cylinder on the back of which a plate is installed parallel to the fluid flow, with different terminal angles, where the reynolds number is 50000. at the end of the plate, blades with the height of 0.25 equal to the cylinder diameter and with 45, 90 and 135 degrees angle from the horizon, are installed where the cylinder diameter is equal t...

Angiomyolipoma is an uncommon benign tumour (hamartsoma) composed of mature or immature fat, thickwalled blood vessels and smooth muscle elements in varying proportions. It is typically found in the young and inpatients with Tuberous Sclerosis Complex (TSC). We present a case of a 55-year old woman who has no TSC. A 55-year old post-menopausal house wife referred a peripheral hospital with subt...

Loading conditions and complex geometry have led the cylinder heads to become the most challenging parts of diesel engines. The aim of this study is to compare the distribution of temperature and stress in the aluminum and magnesium cylinder heads under thermo-mechanical loads. The three-dimensional model of the cylinder heads was simulated in abaqus software and a two-layer viscoplasticity mod...
