Significant efforts should be devoted to reducing waste outputs from aquaculture operations in order to lower the environmental impacts of aquaculture in many parts of the world. Since most aquaculture wastes are ultimately from dietary origin, reduction of waste outputs should first be through improvements of diet formulation and feeding strategies. The first step in the production of feeds producing less solid waste is to eliminate poorly digestible ingredients (such as whole grain or grain byproducts used as bi...

Tourism sector provides employment to the 7\% of workers in the world. It becomes a very important “export” opportunity in the countries where the level of income is low. Besides the benefits of tourism activities in local cultures and eco-systems, it also has irrecoverable negative effects. However, new opportunities provided by “alternative tourism” change this situation. Interests to travels having minimum negative effects on current natural and cultural richness and which are satisfactory in terms of education...

For a better definition of the Actual Climatic Optimum (the so called “global warming”) a detailed analysis of the Holocene climate is imperative. This paper broaches this analysis from the perspective of the “mini-glaciations” climatic cycle with a 1,000 yrs period which a series of authors took into consideration. The causes of these cycles are represented by periodical variations of the solar activity. But our analysis has covered a larger stratigraphical interval (23,000 yrs) including the W\"urm III stadial a...

The detailed modeling of sedimentary media (alluvial sediments, deltas, etc.) that form important aquifers is very complex for two reasons. The first is the intrinsic natural heterogeneity of the geological medium and the second is that the data management tools (manipulating geological and hydrogeological data) needed to implement them in the hydrogeological models are not developed enough. The paper presents a software platform containing methodologies and tools that facilitate the integration of the 3D geologic...

The mineral springs are deep but they cause spills near to the ground surface. In ancient times, buildings have been erected at the level of the spills, and water has been used for heating. Nowadays, the ground surface is some 12 m over the mineral water spills. The structures of the new metropolitan railway are 15-20 m under the ground surface which means that they have to pass through Pliocene clays soften by the mineral water. These specific geological conditions require a specific approach of underground const...

Numerical models which are used for determining deformation are created as a simplified form of physical reality and they are usually defined as force or timedependent. The deformation is investigated by static, kinematic and dynamic models. From these models, dynamic deformation model describes the relationship between the forces and the changes of forces depending on time and the external factors which cause deformation. The deformation in an area is determined by evaluating together the theoretical dynamic mode...

Hydraulic impact hammers are one of the mechanical excavators that can be economically used in tunneling projects under favorable geologic conditions. However, there is relatively less published material in the literature directed to their performance prediction in terms of rock properties. In tunnel drivage projects, there is often the need for accurate means of performance prediction of related mechanical excavators. A poor prediction of machine performance can lead to very costly contractual claims. In this stu...

Geotextiles are used commonly in domestic solid waste disposal sites as a protector filter and separator. Because, sand and silt particles included in waste leachate can fill space of gravels which are using as drainage layers. Therefore, the space of the drainage layer is bunged up with particles and it is decompose. This case is not wanted so the usage of the geotextiles has quite importance in waste disposal sites. In general, geotextile lies between waste and drainage layers and it is used to filtration. In or...

Phosphorus (P) waste output, notably in the dissolved form (DWP), is a major concern for many fish culture operations. Fish are believed to excrete DWP via the urine but this aspect has never been examined in detail. A better understanding of P utilization and renal P handling of fish could aid development of nutritional strategies for the management and reduction P waste. Rainbow trout were fed high corn gluten meal diets, supplemented with dibasic calcium phosphate, containing increasing P levels (0, 75; 1, 15; ...
