This paper presents results of testing twelve hollow square reinforced concrete specimens wrapped with Carbon fibre reinforced polymer CFRP. The effect of ply configuration on the behaviour of the specimens is investigated. All specimens were 800mm high and had the dimensions of 200mm× 200mm in cross-section and a hollow core of 80mm× 80mm. The specimens were divided into four groups with three...

In order to optimize the continuous rolling schedule for improving the quality of rolled tube billet, three dimensional thermal mechanical coupled finite element simulation is applied to analyse the multi-pass continuous rolling process of Ф100mm 37Mn5 steel tube billet from 200mm×200mm square cast bloom. Due to the larger plastic strain occurring at the corner area of the billet, the bias mesh...

Six inbred lines of rice exhibiting differential tolerance to salinity were exposed to 0, 50, 75, 100 and 200mM NaCl for 24, 48, 72 and 96 h. The salinity induced metabolic changes (solute leakage, K efflux and α-amylase activity) were studied during germination. Germination of rice seeds was not affected by NaCl concentration less than 100mM. At higher salinity levels (100 & 200mM NaCl), a del...

Malignant hypertension is a complication of hypertension characterized by elevated blood pressure (200mm/140mm Hg), is considered a medical emergency and is rarely secondary to paraganglioma. Malignant hypertension is unique in its relationship to a catecholamine secreting paraganglioma. We present two rare cases of malignant hypertension associated with paraganglioma of tonsil and urinary blad...

Nail consistency is a little studied characteristic of the nail plate. Numerous factors can influence its determination, including anatomy apparatus, structure plate, and type quantity keratins present. To study relationship between expression level I keratins, sample was chosen 32 individuals in same age group (49.94 ± 3.38 years), 18 with hard nails 14 soft nails, number for each gender. Two ...

We studied the resistance of Cenococcum geophilum and Suillus granulatus isolates to NaCl during growth under axenic culture conditions. C. geophilum isolates displayed variations in NaCl resistance; mycelial growth of most isolates was inhibited above 200mM. All isolates of S. granulatus were tolerant to high NaCl content.

The most widely used material after water is the concrete composite. However, it commonly accepted that weak in tension compared to its compression, therefore, conventionally, usually reinforced with steel rebars. Recently, reusing of waste plastic materials has become a norm among researchers whom different forms improving some mechanical properties such as impact and tensile strength. using P...

A simple, practical model for estimating daily recharge as hydrologically effective rainfall (HER) to the Chalk outcrop of southern England is presented. Daily meteorological observations are the only data requirements. The model was calibrated for a Chalk river, the Wey, in south Dorset. Six different root constant thresholds were used to estimate daily actual evapotranspiration (AET) rates fo...

In this paper we review our work in the field of heterogeneous III-V semiconductor/silicon photonic integrated circuits for application in Fiber-to-the-Home optical access networks and chip-scale optical interconnects. Several optical and opto-electronic components realized on this platform are described. The fabrication of the silicon waveguide structures is done in a CMOS pilot line on 200mm ...
