The system has capability to accurately control ambient temperature against hydration temperature generated by a fully insulated concrete specimens. Also it is capable of simulating any cooling rate which might occur on site and which depends on thickness of concrete element, type of formwork, ambient temperature, humidity and wind velocity Data of concrete of different compositions used at 20 C and 5 C and 35 C are compared with data of concrete cured using semiadiabatic conditions and effect of simulating cooling-time curve is discussed on light of results of strength porosity and permeabitlity. The influence of fly ash on properties of concrete cured at the different environments is also highlighted. article Tue, 01 Jan 2002 00:00:00 GMT https://repository.sustech.edu/handle/123456789/16134 2002-01-01T00:00:00Z https://repository.sustech.edu/handle/123456789/16135 SPIN AND ELECTROWEAK EFFECTS IN e+ e- PAIR NEUTRINO ANNIHILATION HAIDAR,NAZIH WAJIH Differential and integrated cross section, as well as, integral forward-backward asymmetries of the e+ e- > v? v annihilation are studied for defferent e+ e- beams polarizations. article Mon, 01 Jan 2001 00:00:00 GMT https://repository.sustech.edu/handle/123456789/16135 2001-01-01T00:00:00Z https://repository.sustech.edu/handle/123456789/16136 MORPHOLOGICAL STUDIED AND CHARACTERSTIC OF ALKALOID CONTENTS OF THE SUDANESE PLANT KNOWN AS (WINCA) MOHAMMED,AWATIF AHMED; HASSAN,GAAFAR MOHAMMEDL A plant grown in Sudan locally named(winca) was studied for its morphological features and its characteristic alkhaloids that determine its classification. It was found that this plant morphologically belongs to the genus Catharanthus. Its checical constituents indicate that it contains the dimmeric indole alkaloid called vinblastine which is not found in the other plant species, confirming that it belongs to the species roseus, hence this plant which is locally grown is Catharanthus roseus. article Tue, 01 Jan 2002 00:00:00 GMT https://repository.sustech.edu/handle/123456789/16136 2002-01-01T00:00:00Z https://repository.sustech.edu/handle/123456789/16137 ANIMAL DISEASE MONITRING AND SURVEILLANCE SYSTEM PROPOSED FOR SUDAN (ADMSSS) ELFADIL,ABDELHAMID AHMED Animal resources in the Sudan face particular challenges, as its efficiency and its economic contribution to the national economy is still below optimum. Inefficiency is largely related to the existence of animal diseases in most parts of the country. Control and eradication of these diseases are of special interest as the world has, in recent years, experienced important changes related to livestock and animal products trade. article Tue, 01 Jan 2002 00:00:00 GMT https://repository.sustech.edu/handle/123456789/16137 2002-01-01T00:00:00Z
