    Incubation temperature during the presowing soaking of seeds plays a significant role in determining the rate and characteristics of post-treatment germination. Three experiments were conducted on sorghum (Sorghum bicolor L Moench) and pearl millet (Pennisetum glaucum L. R. Br.) genotypes to determine the influence of constant, alternating, ascending and descending temperature regimes on germination characteristics of seeds after treatment. Incubation temperatures ranging from 10 to 35C were applied as well as alternating the magnitude and range of day/night temperatures. A third experiment tested a 3-day temperature gradient and its impact on germination and seedling characteristics. All three incubation temperature regimes were combined with various hormonal and mineral seed soaking treatments to test for possible interactive effects. Temperature did not affect the final germination percentage of seeds but influenced the germination rate. Constant temperatures of 20 or 25C induced higher germinative capacity than alternating or constant temperatures of higher or lower magnitude. Increasing the variance in day/night temperature reduced the rate of germination. Incubating seeds during soaking treatments at a constant 20C for 3 days yielded better germination characteristics than a thermal gradient of 25/20/15C. An 8 g l1 NaCl treatment induced greater plumule (shoot) growth than non-treated counterparts and treating seeds with GA3 or salts improved germination characteristics and synchrony of treated seed lots

    Private Universities of Bangladesh: A Study on Service Quality, Customers’ Perceptions and Satisfaction

    Get PDF
    The higher education sector of Bangladesh is divided as private and public sectors in terms of the initiative of establishment. All of them are autonomous where the public universities are owned by the government and the private universities have been developed by the private sector. As the private universities produce services and sell it to the students by a comprehensive marketing effort, we can treat their services as a part of marketing. In this study, we tried to show the quality of services and the subsequent perception and satisfaction level of the stake holders regarding services are being provided by the private universities along with some recommendations to improve their service quality. For primary data, we interviewed 500 students and their guardians, teachers and staffs of private universities and also some famous educationists of Bangladesh though out Dhaka city through the cluster sampling of probability method; and we also used much enriched secondary sources of data. As our targeted readers are the mass people of the country

    Penelitian ini berjudul, pemeriksaan tersangka oleh penyidik berdasarkan kitab undang-undang hukum acara pidana dengan rumusan masalah yaitu bagaimanakah bentuk pemeriksaan tersangka oleh polisi penyidik dalam KUHAP dan apakah faktor penghambat dalam pemeriksaan tersamgka oleh Polisi penyidik dalam KUHAP. Adapun tujuan penelitian ini yaitu untuk mengetahui bentuk pemeriksaan tersangka oleh polisi penyidik dalam KUHAP dan untuk mengetahui faktor penghamabt dalam pemeriksaan tersamgka oleh Polisi penyidik dalam KUHAP. Metode penelitian yang digunakan yaitu Penelitian hukum dapat dibedakan dalam penelitian yang bersifat normatif dan doktrinal. Penelitian normatif adalah penelitian peraturan Perundang-undangan. Penelitian doktrinal adalah penelitian terhadap asas-asas hukum, pandangan-pandangan para sarjana hukum, literatur hukum dan kegiatan perbandingan hukum. Dalam hasil penelitian bahwa bentuk pemeriksaan tersangka oleh polisi penyidik dalam KUHAP adalah mempergunakan sistem pemeriksan “akuisatur”, dimana sitersangka diproyeksikan sebagai subjek hukum dan bukan sebagai objek pemeriksan. Yang menjadi objek pemeriksaan adalah kesalahan atau perbuatan yang disangkakan kepada tersangka

    Research and development in science and technology in GCC countries: role of information centres and libraries

    This research study identifies the role of library and information centres at the major science and technology related universities and research institutes in the six GeC countries i.e. Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and United Arab Emirates, in relation to the institutes/organisations research and development activities. It also had a comparative aspect in that it examined information resources and information services available in the institutes/organisations under study with users perceptions on the effectiveness and efficiency of library and information services. A survey research design utilizing questionnaires was chosen as the most appropriate and effective method for gathering the data needed with intensive interviews with academe, Deans/Directors of Library Information Centres and R&D personnel to answer the study's research questions. The different populations were queried including the Chief Executives of institutes/organisations, Deans/Directors of Library and Information Centres and selected R&D personnel associated with them. It was found that in spite of large library collections and a number of de-centralised library systems in all the universities, information services available to the R&D personnel were inadequate. The fmdings of this investigation provided the means for the development of the proposed regional and national library/information network systems for successful library and information services model presented in this study. As an alternative a GeC infonnation subsystem GCC-SIST has been recommended along with emphasis on an electronic information system

    Environmental Impact Assessment and Sedimentology of the Carbonate Quarry Site for Al-Maroua'ah Cement Plant in Al-Hodeida District, NW Yemen

    In this study, environmental impact assessment and sedimentology includes chemical analysis were carried out for the quarry site of the limestone raw material in Al-Maroua'ah cement plant in Tehama plane, Al-Hodeida district NW Yemen. The study includes the assessment of the limestone raw materials, the quality, chemical and mineralogical analysis and expected pollutions impact in the quarry site. The studied rock successions are belonging to the Amran Group, which is composed mainly of limestone rocks with few interbedded marl, shale and sandstone beds. The chemical analysis of the limestone rocks show CaO content is (50.31%), with very little MgO content (0.71%). The present shale marl and sandstone rock units are useful for the correction of the rocks to concise with the international specifications of the cement production. The site of the quarry of the main raw materials of limestone rocks was selected far From the villages and human populations to prevent the environmental pollutions according to the WHO and YEPA specifications. The emitted dust from the operations of the quarry machine makes impacts on the surrounding environments especially for the farms and the natural plants and animals, which are living in the region. For this, the site of quarry is selected in a mountain far from the vegetation, population and villages to avoid the expected environmental impact. Mitigation plan for prevent or decreases the pollution impact to the minimum, was discussed
