IMPROVEMENT OF THE CONCRETE CHARACTERISTICS BY USING SUGAR INDUSTRY WASTES (VINASSE)
The current study is concerning with the effect of adding (VSW 2016) to the concrete properties for both fresh and hardened states, concerning of maximizing the benefits from the vinasse liquid, which is produced in Egyptian Sugar & Integrated Industries Company (ESIIC). This is due to the fact that vinasse is by a-product from fermentation and distillation of the Molasses liquid which is the sugar industry product. Vinasse liquid is a secondary product of sugar industry. It consists of mixture from water, organic material and inorganic slats. Some pre-experiments have been carried out on the (VSW 2016) liquid as a plasticizer for mixtures of cements. It was proved from primary results that the (VSW 2016) solution has improved the consistency characteristics and compressive strength of concrete. These results are considered promising results for cement mixtures in general and encouraged continuing the detailed studies to assure the efficient use of (VSW 2016) addition in different applications of building and housing works. Therefore, the main purpose of this research is to study experimentally the mechanism effect of suggested admixture (VSW 2016) on concrete characteristics.

TITANIUM ENVELOPE: TOWARDS ICONIC PROJECTS TO CHANGE THE IMAGE OF KUWAIT CITY SHEIKH JABER ALAHMAD CULTURAL CENTER
Because of quick changes in technology and switching from local to a globalized world, countries and cities are compelled to compete for one another to become an attractive workplace, social and cultural traveller destination. This paper introduces a new iconic architectural project in Kuwait “Sheikh Jaber Al Ahmed Cultural Centre”, which used Titanium for the first time in the Middle East as a building envelope. The paper deals with the material and how it was employed in the building to deliver a unique design. The project was required as a national demand to meet the needs of the citizens culturally and to change the visual image of Kuwait City as well. The work aims to tackle how successful the experiment is by Qualitative and Quantitative framework methods. Two well-documented topics: Titanium as a promising architectural material, and Sheikh Jaber Al Ahmed Cultural Centre design in Kuwait as a global iconic project have been discussed to cover the pros and cons of each, followed by an analysed questionnaire that measures the project role in enhancement of the visual image of Kuwait City In addition to the development of cultural life among Kuwait residents.

URBAN FACTORS AFFECTING ON TRAVEL PATTERN AND BEHAVIOR IN ASSIUT CITY
There is an increased interest to understand and evaluate travel patterns and behaviors, as an attempt to understand travel choices and to identify priorities for interventions. Factors affecting travel choices and behavior were divided into two main groups: non-urban factors and urban factors. This study examined the effect of some various land-use factors on the behavior of the inhabitants of Assiut city-Egypt and measured the preferences of users for special and alternative modes of mechanical mobility in an attempt to determine the required and urgent development priorities to improve transportation services and change travel behaviors toward sustainability. The study was based on an analytical descriptive method. The database was derived from a field study of Assiut city during the period (January 2017 to March 2017). The data were collected through: urban survey of the urban environment supporting the mobility style and behavior of the respondents, in different neighborhoods in Assiut city. During the same period, the researchers distributed a questionnaire at work centers, educational services and some commercial services sites in Assiut. The relative weights for factors limiting the use of alternative means by individuals as well as factors encouraging individuals to use alternative means of transport were determined. The study concluded that mixed land use alone is not enough to reduce mobility and to encourage individuals to move without using mechanical or motorized ways. It should be accompanied with a balanced diversity distribution of services with access by multiple means of transport. In addition, the use of mixed and diverse land use and the shortness of travel distance has a stronger impact on the quality and efficiency of pedestrian corridors and their transit areas on increasing pedestrian mobility, while the quality and efficiency of the cycling infrastructure has been found to be more effective than the limited mobility of bicycles. People's behavior and choices are affected primarily by the quality and efficiency of transport services provided, rather than by mobility costs, and the need to combine pricing policies with urban and planning procedures to change mobility behaviors and to lead to more sustainable behaviors. The paper concluded with a set of recommendations on sustainable mobility and land use in an integrated framework.

URBAN HERITAGE SITES IN MOUNTAINOUS AREAS AS A SUSTAINABLE TOURISTIC DESTINATION ASSESSMENT STUDY OF ARAB MODELS.
The Most of Arab countries have rich heritage assets، as the Arab region is the origin of civilizations and the culture interaction area during ages، which produces these assets that attracting tourists from all over the world. Some of the urban heritage sites in Arab countries located in mountainous areas. These sites characterized by their attractive features for their heritage value، and the natural environment as well as their charming views. The heritage sites that are located in mountainous areas placed in the circle of concern of their governments، and they put them on the priorities list in the national plans of development compared to the heritage sites that aren't located in mountainous areas. The governments also seek for some of these sites to be in the world heritage list of UNESCO. The current global trend for applying of the concept of sustainable in the tourism، as well as the concern of governments and international tourism agencies lead to set new policies to promote sustainable practices in the tourism sector and to transform important touristic destinations into sustainable tourism destinations. For that، the Global Sustainable Tourism Council (GSTC) set a group of global criteria for sustainable tourism that can be applicable by the administrations of touristic destinations to transform these destinations to sustainable touristic heritage sites. The research analyses three Arab heritage sites that are located in mountainous areas as: saint Catherine monastery and Moussa Mountain in Sinai- Egypt، Rijal Almaa' Village in Assir- Saudi Arabia، and the lady of Lebanon site in Harissa- Lebanon. The research aims to assess these heritage touristic destinations according to the global tourism sustainable criteria، to assess the current state of these destinations، then set a recommendations to transform these heritage sites to be sustainable touristic destinations. The results and the recommendations of the research also can be applicable on the other heritage sites that are located in mountainous areas.

THE CURRENT METHODOLOGY OF ASSESSMENT OF SUSTAINABLE BUILDINGS IN EGYPT BETWEEN PROBABILITIES AND OBSTACLES
Sustainable architecture is a tool for designing and constructing buildings in order to reduce the negative effects of the building on the environment and to meet the current needs without ignoring the rights of the next generation. The increasing interest of green buildings in Egypt reflects the awareness of governments, local organizations and architects of the importance of incorporating and applying the comprehensive approach of sustainability in the field of architectural design. The adopting of sustainable buildings rating system is one of the goals of sustainable development in Egypt. Although Egypt adopted a local rating system for sustainable buildings which is “Green Pyramids Rating System”, there is no approved buildings by using GPRS however the density of construction activities in Egypt. The literature review shows that, the current sustainable buildings rating system in Egypt cannot be used to conduct a comprehensive assessment during the early stages of architectural design and to reevaluate the building after the construction process. In addition to the administrative obstacles and the negative aspects of GPRS, the research problem includes also the technical challenges and the problems related to people who do the evaluation. This paper investigates the development of sustainable buildings evaluation process in Egypt and the current institutions responsible for evaluating the sustainability of buildings. The main potentials and available chances for developing sustainable architectural design have been clarified. On the other hand, the current challenges which obstacle rating the sustainable buildings in Egypt were clarified. The present paper recommends some suggestions to achieve comprehensive for buildings in terms of environmental, economic and social issues and to encourage the development of materials and construction systems which are environmentally friendly.
