Community Diagnosis

It is clear that construction and demolition wastes (CDW) are constantly increasing throughout the world and these wastes can be used effectively to minimize the consumption of natural resources in the manufacture of more sustainable concrete. The CDW occupy an important segment of world waste production and its generation reached approximately 3 billion tons in 2012 in 40 countries [1]. Although this topic has been studied in the world, it is still valid for the reuse of waste that is constantly increasing, and although in many countries there are already examples of its use this type of concrete in Colombia and in the Medellìn city lacks applications. This project proposes the application of a sustainable concrete made with CDW and coal ash in the Medellín city for its implementation in the construction of urban furniture. A university community diagnosis of the needs in terms of furnishing was made. With the design reached, a modular chair was proposed to enable spaces within the university. The mechanical characteristics of the concrete and the design of the chair are evaluated and a simulation is done through finite elements to evaluate the viability of the proposed concrete, finding that with these properties is possible to manufacture durable and sustainable furniture that serves as an example for the application of sustainable materials

Day By Day

With the increasing population of the world, the rate of development of infrastructure is increasing day by day; which has placed a massive demand for natural aggregates. Besides, huge amount of demolished construction wastes are generated all over the world which creates pressure on the environment as well as landfills. Therefore, it is necessary to find a sustainable solution to adopt these C&D wastes as an alternative to natural aggregates for construction purposes. Therefore, the objective of the present study is to explore the influence of superplasticizers while adopting recycled brick aggregate (RBA) in the sustainable concrete application as a coarse aggregate. Six different mixes are considered with 100% replacement of recycled brick aggregate and three diverse water-cement (w/c) ratios, such as 0.40, 0.45, and 0.50. To improve the workability and mechanical characteristics of concrete a superplasticizer is used as an admixture. Fresh properties of concrete, compressive strength at normal and high temperatures, flexural strength and splitting tensile strength are presented. The results indicate that addion of superplasticizer improves slump values and reduces air voids of concrete. Although strengths of RBA concrete are lesser than the virgin brick aggregate concrete, they are still satisfactory in the application for structural concrete and can be also significantly improved by incorporating admixture. Finally, this research will help to recycle the brick aggregate instead of dumping it as waste in a landfill.

Excerpta Medica Foundation

A joint center has been established by the University of Pittsburgh and the Excerpta Medica Foundation. The basic objective of the Center is to seek ways in which the health sciences community may achieve increasingly convenient and economical access to scientific findings. The research center will make use of facilities and resources of both participating institutions. Cooperating from the University of Pittsburgh will be the School of Medicine, the Computation and Data Processing Center, and the Knowledge Availability Systems (KAS) Center. The KAS Center is an interdisciplinary organization engaging in research, operations, and teaching in the information sciences.Excerpta Medica Foundation, which is the largest international medical abstracting service in the world, with offices in Amsterdam, New York, London, Milan, Tokyo and Buenos Aires, will draw on its permanent medical staff of 54 specialists in charge of the 35 abstracting journals and other reference works prepared and published by the Foundation, the 700 eminent clinicians and researchers represented on its International Editorial Boards, and the 6,000 physicians who participate in its abstracting programs throughout the world. Excerpta Medica will also make available to the Center its long experience in the field, as well as its extensive resources of medical information accumulated during the Foundation’s twenty years of existence. These consist of over 1,300,000 English-language _abstract of the world’s biomedical literature, indexes to its abstracting journals, and the microfilm library in which complete original texts of all the 3,000 primary biomedical journals, monitored by Excerpta Medica in Amsterdam are stored since 1960.The objectives of the program of the combined Center include: (1) establishing a firm base of user relevance data; (2) developing improved vocabulary control mechanisms; (3) developing means of determining confidence limits of vocabulary control mechanisms in terms of user relevance data; 4. developing and field testing of new or improved media for providing medical literature to users; 5. developing methods for determining the relationship between learning and relevance in medical information storage and retrieval systems’; and (6) exploring automatic methods for retrospective searching of the specialized indexes of Excerpta Medica.The priority projects to be undertaken by the Center are (1) the investigation of the information needs of medical scientists, and (2) the development of a highly detailed Master List of Biomedical Indexing Terms. Excerpta Medica has already been at work on the latter project for several years.

كان من أهم الآثار الإيجابية للصحوة الإسلامية التى عمت العالم الإسلامى بشكل ملحوظ منذ أوائل السبعينيات فى القرن العشرين زيادة إقبال الشعوب الإسلامية على تعلم اللغة العربية، وبدأ الاهتمام الحقيقى لجامعات العالم الإسلامى بتوفير مساقات متخصصة لهذا الغرض منذ أوائل الثمانينات، وكانت الجامعة الإسلامية العالمية بماليزيا التى أسست سنة 1983 من أنشط الجامعات فى هذا الصدد، وهو نشاط استلفت نظر الباحث إذ وجده يستحق الرصد والتوثيق العلمى، والمراجعة إذا اقتضت الضرورة لا بهدف الإشادة بالتجربة بل رغبة فى الإفادة والاستفادة من قبل المختصين من المهتمين بهذا الميدان الحيوى من ميادين خدمة اللغة العربية بل خدمة الإسلام، وحضارته نظرا للارتباط الوثيق بين اللغة العربية وهذا الدين الحنيف باعتبارها لغة كتابه الخالد، والمعلم الرئيس من معالم الهوية الإسلامية المميزة والصمود الحضارى.*****************************************************One of the most positive effects of the Islamic awakening since the early seventies, in the twentieth century, which spread across the Islamic world in a significant manner, has been the increased Muslims’ interest in learning the Arabic language all over the world. There began a real interest in the universities of the Muslim world for the Arabic language by providing specialized courses for this purpose since the early eighties and  the International Islamic University Malaysia established in 1983 has been the most active university in this regard. And this activity of the university drew the interest of the researcher who found it worthy of investigation and scientific documentation as well as of revision, if necessary, not in order to pay tribute to the experience, but for taking advantage and learning from specialists interested in this vital field of the fields of Arabic language service which is actually service of Islam and its civilization considering the strong connection between Islam and the Arabic language, the language of the Qur’Én , the most distinctive feature of Islamic identity and resilience of Islamic civilization.

Social Consideration

There is a culture of disengagement from social consideration in engineering disciplines. This means that first year engineering students, who arrive planning to change the world through engineering, lose this passion as they progress through the engineering curriculum. The community driven technology innovation and investment program described in this paper is an attempt to reverse this trend by fusing community engagement with the normal engineering design process. This approach differs from existing project or trip based approaches – outreach – because the focus is on local communities with which the university team forms a long-term partnership through weekly in-person meetings and community driven problem statements – engagement.

Do So

Wherefore is light given to him that is in misery, and life unto the bitter in soul?' Jude Fawley, poor and working-class, longs to study at the University of Christminster, but he is rebuffed, and trapped in a loveless marriage. He falls in love with his unconventional cousin Sue Bridehead, and their refusal to marry when free to do so confirms their rejection of and by the world around them. The shocking fate that overtakes them is an indictment of a rigid and uncaring society. Hardy's last and most controversial novel, Jude the Obscure caused outrage when it was published in 1895. This is the first truly critical edition, taking account of the changes that Hardy made over twenty-five years. It includes a new chronology and bibliography and substantially revised notes.
