Influence of Different Irrigation Regimes on the Phenology and Accumulated Heat Units in Four Bread Wheat Cultivars
M.Z. Alam,S.A. Haider,N.K. Paul
Pakistan Journal of Biological Sciences , 2004,
Abstract: A field investigation was carried out to study the influence of irrigation on phenology and accumulated heat units of four cultivars of bread wheat (Triticum aestivum L.) at different phenological stages over two growing seasons. There were three treatments: rainfed, 10 and 20 mm irrigation. The rainfed plants had significantly shorter phenological stages and lower growing day degree than the irrigated plants in all the four cultivars. Cultivars Akbar was found to be early and C 306 was found to be late maturing. Akbar had the lowest and C 306 had the highest growing degree days during all the phenological stages under each irrigation regime. Heliothermal units also showed more or less the same trends. The phenothermal indices and heat use efficiency were found to be higher in the irrigated plants than the rainfed plants.
Influence of Different Sowing Dates on the Phenology and Accumulated Heat Units in Wheat
S.A. Haider,M.Z. Alam,M.F. Alam,N.K. Paul
Journal of Biological Sciences , 2003,
Abstract: A field investigation was carried out to study the influence of sowing dates on phenology and accumulated heat units of four cultivars of bread wheat (Triticum aestivum L.) at different phenological stages over two growing seasons. There were two sowing dates: early and late. The late sown plants had significantly shorter phenological stages and lower growing day degree than the early sown plants in all the four cultivars. Cultivars Akbar was found to be early and C 306 was found to be late maturing. Akbar had the lowest and C 306 had the highest growing degree days during all the phenological stages under each irrigation regimes. Heliothermal units also showed more or less the same trends. The phenothermal indices and heat use efficiency were found to be higher in the early sown plants than the late sown plants.
Spectroscopy and thermal studies of the reaction of iodine with cobalt (II) and copper (II) acetylacetonate
Sadeek,S.A.;
Anales de la Asociaci?3n Qu?-mica Argentina , 2005,
Abstract: a spectrophotometric study of 1:1 charge-transfer complexes derived from two metal acetylacetonates ( co (ii) and cu (ii) acetylacetonates) donor and iodine ( s-acceptor ) has been carried out. the equilibrium constants ( k ) and absortivity ( e ) for the formation of the chelate-iodine complexes have been evaluated. the suggested structure of the two solid triiodide charge-transfer complexes reported in this study is further supported by thermal analysis and far and mid infrared measurements.
Exploring knowledge and attitudes towards counselling about vitamin supplements in Jordanian community pharmacies
Shilbayeh,S.A.;
Pharmacy Practice (Internet) , 2011, DOI: 10.4321/S1886-36552011000400010
Abstract: the use of multivitamins within a pharmaceutical setting has been the subject of considerable debate. objective: this research aimed to provide a platform for assessing and evaluating knowledge, attitudes and professional practices of jordaninan community pharmacists in counselling patients about the safe consumption of vitamins. methods: a cross-sectional study was conducted between october 2009 and may 2010. data collection was carried out using a 44-item semi-structured self-administrated questionnaire. setting: community pharmacies in amman with target sample of 400 pharmacists. results: a total of 388 pharmacists participated in this study. the majority (77.8%) of pharmacists believed that a balanced diet is more achievable by eating healthily than by vitamins supplements. 78.1% of participants believed that vitamins deficiency would not shorten life spans, while 80.7% agreed that vitamin supplements could be toxic or might contain unlabelled harmful ingredients. less than half of pharmacists were aware that some antioxidant vitamins have been verified to be of unproven value, or may even cause cancer. while over 80% of pharmacists would recommend vitamins on a regular basis without prescription, the majority agreed that counselling on vitamin supplements is part of their role in pharmaceutical care (93.3%), in addition to providing relevant information to other healthcare professionals (78.4%). moreover, responses to specific knowledge questions, such as the interactions of vitamins with drugs or the recommended dietary allowance of vitamins for infants, children, and pregnant women, were negative. furthermore, only a minority of pharmacists would recheck the accuracy of dose regimens in prescriptions and symptoms of true vitamins deficiency or would follow up patients to record any consequences of vitamins consumption. conclusion: the questionnaire revealed satisfactory awareness of community pharmacists about their role in counselling; however, further progr

Grondtrekke van Adrio K nig se teologie
S.A Strauss
Acta Theologica , 2005,
Abstract: In 2001 Adrio K nig published a book Focus on 300 questions about faith, which most people ask (title translated). Basically this book can be regarde as a summary of K nig’s systematic theology. K nig’s theology is so stimulating that it deserves research. This article analyses Focus, with reference to other books by the same author, aiming at disclosing the basic features of his theology. The article concludes that K nig’s theology can be described, from a reformed perspective, as ambiguous: biblical as well as contextual, confessional as well as ecumenical. K nig describes his theology as “eschatological covenant theology”. The positive and negative implications are also discussed.
Reformed theology for the 21st century: confessional, contextual and ecumenical
S.A Strauss
Acta Theologica , 2005,
Abstract: This article scrutinises two important, recently published books on the identity of Reformed theology. These books serve as a springboard for the formation of ideas concerning the way in which Reformed theology should be practised in the 21st century. The article tests the hypothesis that the correct connection and relationship between confession, context and ecumenicity guarantees the practising of meaningful, thorough and useful Reformed theology.
The uniqueness of Jesus Christ and pluralism from the perspective of the reformed confession
S.A Strauss
Acta Theologica , 2006,
Abstract: This article investigates the current issue of the relationship between Christian and non-Christian religions in multi-religious societies. The philosophical backgrounds of the pluralistic approach are summarised. Subsequently the (Dutch) Reformed confessions are scrutinised for Biblical guidelines which may be helpful in finding a solution for the problem of being Christians in a multi-religious society. It is argued that pluralism must be rejected, while both inclusivism and exclusivism can also not be accepted uncritically.
Nigerian Student s Perception of Technical Words in the Senior Secondary School Chemistry Curriculum
S.A. Jegede
Pakistan Journal of Social Sciences , 2012, DOI: 10.3923/pjssci.2010.109.111
Abstract: This study looked at how much students understand technical words in chemistry as a means of solving the problem of under-achievement of chemistry students at the secondary school level. The instrument of the study was a six-point scale questionnaire designed by the researcher for the purpose of the study. It was administered to 150 subjects from ten randomly selected schools in Ado and Moba Local Government Areas of Ekiti State. Results show that students perceived 20 of the 30 identified technical words/terms from the senior secondary school curriculum as difficult to understand.
Wireless Data Transmission Based on Adaptive Modulation and ARQ Control
S.A. Emad
Journal of Engineering and Applied Sciences , 2012,
Abstract: Radio transmissions need to be intelligent and reconfigurable to control quality of service (QoS). QoS can be controlled using both adaptive modulations in conjunction with hybrid type of error control mechanism at the data link layer. In this study adaptive modulation is used as a powerful technique to improve the tradeoff between spectral efficiency and Bit Error Rate (BER). The adaptation also takes into account the requirements of different traffic services such as required BER and packet loss. The receiver estimates the received Signal to Noise ratio (SNR) and sends the feedback information via a feedback channel to the transmitter, which determines the suitable modulation constellation to be used over the channel. The proposed adaptive communication system uses a combination of Forward Error Correction (FEC) and Automatic Repeat Request (ARQ) in order to get efficient and reliable real time data communication over wireless channel.
