Ask ChatGPT about the research

Hydraulic drives are able to generate high forces and move large loads. With the help of proportional valves, it is possible to control movements fast and accurately. Depending on the application, a linear cylinder, a rotary cylinder or a rotary motor are used. Linear cylinders are most frequently used. The following designs are therefore confined to this type of drive. We compare among various types of cylinders which are common by used. We compared different conditions for cylinders with friction and without it.

In this research, technical fabrics are used as blankets which prevent soil surface erosion and promote seed germination as way to mitigation of desertification . Five different types of fabrics are prepared of natural fiber: coir, hemp, jute, trea ted cotton and raw cotton, then three hydraulic properties for prepared fabrics are tested: swell, water absorption, water vapour permeability. It is found that all types of prepared fabrics are suitable to combat desertification whereas they have a high water absorption and they reduce water evaporation, the fabrics of jute and treated cotton have the highest water absorption and the fabrics of hemp and raw cotton have the lowest water vapour permeability.
The research aims to complete the study of the theory and operation of networks geodesic associated marine beach, whether horizontal or vertical, with display rods and devices used in completion of topographic survey of networks in both land and ma rine parts. In theoretical part it was addressed to specific shapes networks geodesic which distinguish maritime works beach that takes the form of the morphological characteristics of the natural land of each building proposed network, and the numerical characteristics of each building proposed networks. In the practical part the results of measurements and amendments was presented to some forms of executed geodesic beach networks for several forms of works: (topographic raise achievements within the existing and investor basin in order to establish a slider, completion of the cadastral beach works in order to determine distortions in the existing pier, clean the shipyard of silt and sediment. Software has been reviewed to assist in completing marine works, utmost to obtain the final marine charts. The research concluded that specific proposals on vertical geodetic networks studies, and identify the various parts of software related to marine works and ways to take advantage of them.
The behavior of the basaltic shear diaphragms of the remaining buildings of ancient times was investigated as experimental research,and its resistance to natural factors and horizontal loads resulting from wind and earthquakes,to take advantage of them in the maintenance of modern buildings,which are associated with floors and beams as horizontal shear diaphragmsIn the hot and cold areas of the African continent, Asia and other similar areas,to replace the reinforced concrete shear diaphragms,and metal shear diaphragms that lose their resistance to the above factors. When the buildings are inspected, the vertical and slanted slits resulting from the side loads are placed,it was found that the appearance of the cracks related to the hardness of the shear diaphragm section, the basalt stone specifications and the design of the shear diaphragm base.The research was conducted to determine the durability, water permeability and resistance to pressure and tensile strength of basalt stone samples used in historic stone buildings and their location in laboratory methods.Horizontal loads resulting from seismic intensity were determined on the front of the building at the tile level according to international requirements and specifications.The method of calculating the basaltic shear diaphragms was applied by applying arithmetic to build a basalt stone from several floors and a basement, taking into account the characteristic resistance of basalt, depending on its density from pressure and stretching and basalt stone in calculating.
The objective of the research is to complete a theoretical and practical study related to coastal marine works in order to calculate the amounts of silt removal from harbor basins and entrances, and to present the methods and devices used in the pe rformance of topographic survey and numerical methods in the calculation and comparison of quantities. In the theoretical part, the factors that lead to the formation of silt deposits in the port basins, the methods of their removal and the deepening of the navigational pathways to enter and exit the harbors were addressed. In the practical part, the results, methods of measurements and topographic results were presented during the stages of investment of the port, at least two stages, at the beginning of the investment and before the process of direct withdrawal, and then calculating the quantities of the implemented and comparing them, to obtain maritime plans and final quantities. The research concluded with specific proposals on the methods of calculating the quantities of the isolated port, the method of constructing the measured geodetic networks, the achievement of the topographic elevation under the water surface, and the identification of the software parts related to the various marine works and ways of benefiting from them.
Research was conducted on a sample of 45 patients in the Department of hemodialysis in Alssad University Hospital in Latakia, It was implemented two policies nursing care included each policy applied on two experimental groups I and II for a period o f 3 months, and the patients were monitored patients using the form author 3 parts of a demographic data and the activities of nursing care and monitoring the occurrence of complications. Results: The results showed the effectiveness of the application of the policy of nursing care, including exercise program in the prevention of the occurrence of complications during hemodialysis, effectiveness of exercise in the prevention of complications during hemodialysis, regardless of the activities of the sports program applied. Conclusions: conclude from the study that the application of the policy of nursing care, including exercise program contributes to the prevention of the occurrence of complications (high / low blood pressure, nausea and vomiting, muscle spasm) during a session of hemodialysis.
