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 marine 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 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.
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 mo tor 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 paper, comparisons between several mathematical interpolation methods applied on high accuracy and huge laser clouds which only represents the DTM. In order to implicate the aforementioned, a group of a variety of Laser Scanned Areas has been chosen to represent different types of terrain including complex and flat terrain, taking into account that man-made features are not involved in this study and that different Laser Clouds density is used to make the study more general. A different set of algorithms were applied to conclude which one is more suitable. This step was followed by the comparison between different interpolation results. The results have shown that the Points' Density has a great impact on a manner in which the optimal interpolation method is applied. Moreover, it has proven that the Nearest Neighbor Algorithm is the best applied method compared with the other alternatives
The research project sample consisted of 30 blocks of composite resin , these blocks where divided into three equal groups , 10 of composite resin Z-250 from 3M ESPE Company , 10 of the composite resin Supreme from 3M ESPE Company ,10 of the composit e resin Quixfil of Dentsply company, and has been testing the hardness Number, each sample individually. The aim of the previous procedures was to show the role of composite resin structure in determining the hardness number Through differences in the hardness number and the role of this hardness determining the mechanical properties for composite resin restorations cause of the importance of this property to understand the mechanical properties for a lot of restorative materials. And the result is that there is a statistically significant between the resin Quixfil and the Z-250 on the one hand and the Supreme resin on the other hand.
The present study aimed to compare the epithelium tissue of mucosa layer of gastrointestinal tract in three types of lower vertebrates: Scyliorhinus canicula, Sparus aurata, Salamandra infraimmaculata. The results of the histological and comparativ e study showed that the majority of digestion system parts were lined with simple epithelium tissue while others were lined by pseudostratified epithelium tissue. Goblet cells were distributed in all studied parts of digestion systems with density in some locations. Esophagus was characterized by ciliated epithelium tissue, and the tubular glands were presents in the stomach mucosa. Concerning the Lumina properia, it was visible in all digestive system parts with some differences according to the animal species studied.
