FLEXURAL STRENGTHENING OF REINFORCED HPC BEAMS INCORPORATED WITH BY-PRODUCTS 2017-11-27T06:24:59+00:00 T. Subbulakshmi B. Vidivelli <p>High performance concrete (HPC) shows better performance when compared to conventional concrete. The concrete having industrial by-products of silica fume, bottom ash and steel slag aggregate distinguished that the structural manner of reinforced concrete beams related to cracking behaviour and load strain manner is investigated in the present study. The beams were designed to have concrete strength of cube compression was 30 – 40 N/mm<sup>2</sup><sub>. </sub>The cracking behaviour, strain distribution and ductility have been studied throughout their flexural loading range, and their mode of failure.</p> 2017-11-27T00:00:00+00:00 ##submission.copyrightStatement## ECONOMIC ANALYSIS OF MEASURES TO CARE CULTURES OF BLACK PINE (Lat.

This measure of care is provided by the high quality of the first tree and reciprocal to&nbsp; the higher income. The authors examine the technical and technological components, and economic effects, highlighting the specificity of the translation results in a tree, in particular.</p> 2017-11-27T06:14:59+00:00 ##submission.copyrightStatement## CLIMATE CHANGE CHALLENGES AND OPPORTUNITIES FOR NON-CONVENTIONAL WATER USE FOR AGRICULTURE IN PALESTINE 2017-12-18T12:53:04+00:00 Sameer Bsharat Zaher Barghouthi Saed Khayat Abdallah Alimari <p>Agriculture is a very important sector in the Palestinian economy, it contributes about 8.1% of the Gross Domestic Product (GDP). However, it is the dominant user of water. Water is the main obstacle facing extending of irrigating agriculture. While Climate change represents new growing challenge for Palestinians through its effects on agricultural productivity and water insecurity. It is likely to alter patterns of water availability, thus adding to the existing restrictions on Palestinian water access imposed by the Israeli side. There is an urgent need for new alternative water resources for agricultural use to alleviate the mounting pressure on drinking water resources. Non-conventional water such as the moderately saline water which is available in the Jericho and Jordan Valley in the Eastern part of the West Bank, and the treated wastewater - represent such alternative resources. However, this needs appropriate policies and research. The contribution will discuss the current status of water and agriculture in addition to climate change challenges that alter the two sectors in two Palestinian Governorates: Jericho and Qalqiliya.</p> 2017-12-18T12:53:04+00:00 ##submission.copyrightStatement##
