With the political, economic and social developments and transformations of the 19th century, and with urban transformations in cities and technological advances that clearly affected living conditions, Old valuable buildings and historic environments may be subjected to many physical neglect due to the deterioration of their architectural and urban status, as well as being neglected physically and morally because they don't adapt to these transformations and the requirements of contemporary life, In order to achieve this, it is possible to reuse, because the original function of valuable buildings of value disappear gradually over time. However, this may be inconsistent with the new urban surroundings. The research presents a new vision linking the appropriate reuse of valuable buildings with upgrading their urban surroundings and raising awareness of the value of these buildings to extend their impact to the economic and civic fields, which may help to create a reliable economic base to keep these buildings having suitable and effective functions in their Urban surroundings

The use of steel slag aggregate in rigid pavement presents a great economical and environmental solution to overcome the decreasing in natural aggregate. The aim of this research is to investigate the potential recycling of Basic Oxygen Furnace Slag (steel slag) in road construction for sustainability an environmental benefit. The steel slag is used as a coarse aggregate replacement in rigid pavement mixes, partly or totally. Recycling ratios of 25%, 50%, 75% and100% are used. The results showed that using steel slag aggregate increases the mechanical properties of concrete, safe to use as aggregate at sulfate attacking when samples were submerged in 5% sulfate solution concentration.

The peak factor (PF) is the proportion of the maximum flow to the average daily flow in a wastewater system. Both of the average and the maximum daily flow are evaluated randomly because there is difference in their values, therefore the corresponding peak factor (PF) may be explained based on a probabilistic theory. In this study, Peak factor equations were developed for different studied areas in Upper Egypt region with different populations and water consumption. Ten years of flow data was collected and measured for the study areas and analyzed to improve the P.F equation. The flow values and P.F values acquired from the developed equations of the studied communities were compared to equations from previous studies

Decreasing the heat rejection of any power cycle is a promising agent in improving the overall performance and decreasing global warming. This can be done by different methods such as heat exchangers or thermosyphons. Water is used as a working fluid. The present experimental work used water as a working fluid and investigated the effects of filling ratio (27.2%≥Fr≥9%), total nozzle exit area to the turbine inlet area (4.3%≥Ar≥2.5%), and condenser cooling water flow rate (16LPM≥(V ̇) ̇≥8LPM). The results showed that the optimum-filling ratio is approximately 13.6% and the output power increases with increasing condenser cooling water flow rate. Also, the maximum output power produced at minimum area ratio but the optimum turbine rotational speed at area ratio of 3.1%. In addition, the maximum output power without load from the present turbine is 5.28 W at Fr= 13.6 %, Ar=2.5% and V ̇=16 LPM
