Response of Banana "Williams Hybrid" to Nitrogen, Phosphorus and Potassium Fertilization

Field experiments were conducted at the National Institute for Promotion of Horticultural Exports (NIPHE) research farm during the period of 2001 to 2002 to determine the effects of nitrogen, phosphorus and potassium levels on growth parameters, earliness, nutrient uptake, yield and yield components of "William's hybrid" banana cultivar. Treatments included 5 N levels (0, 69, 138, 207 and 276g N/mat/year), 2 P levels (0 and 20 g P/mat/year) and 2 K levels (0 and 41 g K/mat/year) . The treatments were arranged in a randomized complete block design with 3 replications. Banana growth, yield and yield components were significantly increased by N and K application. The highest vegetative growth parameters, yield and yield components were obtained with the application of 207 g N/mat/year in combination with 41 g K/mat/year. Application of N in combination with K also resulted in a significant reduction in the period from plant-ing to shooting and from shooting to fruit maturation. The shortest number of days to shooting were obtained with the application of 276 g N/mat/year. Application of N, P and K also resulted in increased leaf N, P and K contents. Application of P alone or in combinations with N and K had no significant effects on growth or yield parameters

Primary Tuberculosis of the Maxillary Sinus: A case report

Tuberculosis is up-to-date a leading cause of human suffering and loss of life. Although tuberculosis is a systemic disease, primary tuberculosis of the paranasal sinuses is rare. It should be kept in mind in any undiagnosed or atypical clinical infection or inflammation in this region. We present here a case of primary paranasal sinuses tuberculosis in an elderly Sudanese woman. Although Sudan is one of the highest three countries in the incidence of tuberculosis, this is the first case to be reported in Suda

Effects of nitrogen source, rate and foliar application on some leaf mineral nutrient contents and yield of “Sinnari” sweet oranges (Citrus sinensis L.) in the River Nile State, Sudan

      Sweet orange production in the Sudan is characterized by low yield and poor fruit quality. This research was aimed at determining the effects of nitrogen source, rate and foliar application on some leaf mineral nutrient content and yield of “Sinnari” sweet oranges in  the River Nile State during 2010/11 and 2011/12. Nitrogen sources were urea (100%), sheep manure (SM) (100%), or a combination of them (50% each), beside Wuxal foliar fertilizer. Nitrogen rates were 0, 43 and 86 kg N/ha. Treatments were arranged in a randomized complete block design with three replicates and 2 trees/plot. Results showed that nitrogen sources and rates were effective in increasing leaf nitrogen content and the highest values were obtained by the application of 86 kg N/ha using urea (100%) or a combination of urea and sheep manure. Application of Wuxal foliar fertilizer resulted in a significant increase of Zn and Fe leaf contents and total yield. Nitrogen source had significant effects on yield components and total yield. The highest values were obtained by a combination of urea and sheep manure or 100% urea, and the lowest values were recorded for 100% sheep manure. Nitrogen rate of 86 kg N/ha resulted in the highest yield components and total yield. It is recommended to fertilize sweet orange trees in the River Nile State with a combination of urea and sheep manure at the rate of 86 kg N/ha (12.4 kg SM/tree and 0.5 kg urea/tree) in addition to Wuxal foliar fertilizer

Current status of sweet orange (Citrus sinensis L.) orchards in the River Nile State, Sudan

ABSTRAC     Production of sweet oranges in the Sudan does not cover domestic needs and sweet oranges are currently imported from Egypt, Iran and South Africa to satisfy the increasing demand. Hence, there is a need to investigate factors involved in the decline of sweet orange trees in one of the most important States for orange production in the Sudan. This research aims to study and evaluate different agronomic practices contributing to the prevailing sweet orange performance in the River Nile State, Sudan. A questionnaire and interviews with 120 sweet orange growers from Ketiab, Zeidab and Gandato citrus projects indicated that 75.8% of the farmers have orchards less than 2.9 ha. Low yielding cultivars such as “Sinnari”, the local selection (Baladi), Hamlin and Nori 16 dominate in the areas, 96.7% of the trees were budded on sour orange rootstocks, 85.8% of the seedlings were budded in private nurseries using bud wood collected from non-certified mother trees from private orchards. All sweet oranges were grown with other fruit species in 100% of the orchards, 80.8% used flat surface irrigation. There is no fixed fertilizer program. The type and quantity of chemical and organic fertilizers varied with different growers. No foliar fertilizers were used and nutrient deficiencies of Zn, Fe and Mn were observed in most orchards. Extension services for citrus production are highly needed for improvement of yield and quality of sweet oranges in the River Nile Stat

Spirituality in entrepreneurship from Islamic perspectives: a conceptual analysis on the effects on entrepreneurial motivation and social responsibility

Spirituality in entrepreneurship as an emerging area of interest has begun to generate attention from management scholars. However, most research in this area is from the western perspective. Until recently, there is dearth of research that gears towards spirituality in Islam and its contribution to the overall development of modern organisations. This exploratory study presents a conceptual analysis of the effects of spirituality in Islam on entrepreneurial motivation, performance and commitment to social responsibility. It has been suggested that spirituality in Islam has the potential to positively influence the entrepreneurial outcomes considered

Entrepreneurial motivation, performance and commitment to social responsibility: a conceptual analysis on the influence of Islamic religiosity

Although the study of religion and its effects on social phenomena had received attention lately, most research in this area is from various religious perspectives excluding Islam. To date there is dearth of precious information regarding Islamic religiosity and its effects on entrepreneurial outcomes. In this exploratory study, a conceptual analysis of the effects of Islamic religiosity on entrepreneurial motivation, performance and commitment to social responsibility is considered. We suggested that Islamic rituals have the potential benefit of fostering the entrepreneurial outcomes considered. We recommend that religious practices be encouraged in the workplace

A new generation for intelligent anti-internet worm early system detection

Worm requires host computer with an address on the Internet and any of several vulnerabilities to create a big threat environment.We propose intelligent early system detection mechanism for detecting internet worm.The mechanism is combined of three techniques: Failure Connection Detection (FCD) which concerns with detecting the internet worm and stealthy worm in which computer infected by the worm by using Artificial Immune System; and the Traffic Signature Detection (TSD) which responsible for detecting traffic signature for the worm; and the DNA Filtering Detection (DNAFD) which converts traffic signature to DNA signature and sending it to all computer that connected with the router to create a firewall for new worms.Our proposed algorithm can detect difficult stealthy internet worm in addition to detecting unknown internet worm

INTESTINAL ABSORPTION OF EPROSARTAN MESYLATE FROM SELF EMULSIFYING SYSTEM AND CYCLODEXTRIN COMPLEX

Objective: The aim of this work was to determine the intestinal membrane transport parameters of eprosartan mesylate (EM) and to investigate self-nano emulsifying drug delivery systems (SNEDDS) and inclusion complexation with hydroxypropyl b cyclodextrin (HPbCD) for enhanced intestinal absorption of eprosartan mesylate. Methods: The intestinal absorption was monitored using the in situ rabbit intestinal perfusion technique. SNEDDS was developed using labrafil, Lauroglycol with a tween in the presence of ethanol. Inclusion complexation was achieved by construction of phase solubility diagram in the presence of HPbCD. The prepared complex was evaluated using Fourier Transform Infrared Spectroscopy (FTIR) and differential scanning calorimetry (DSC). Results: The drug was found to be poorly absorbed from the jejuno-ileum and the colon with the absorption being mainly through paracellular pathway. An inclusion complex was developed between the drug and HPβCD. Perfusion of the drug in the nanoemulsion formulation or as an inclusion complex resulted in a significant increase in the intestinal absorption of the drug compared with the control.Conclusion: SNEDDS and inclusion complexation are promising strategies for enhanced intestinal absorption of eprosartan mesylate

The effect of piety on organizational citizenship behavior (OCB) from Islamic perspective: a study of professionals in Southeast Asia

Although Organizational Citizenship Behavior (OCB) has received much attention from contemporary researchers, very little research has been done from religious perspectives. This research attempts to enrich the understanding of OCB from Islamic Management perspective, particularly the application of Piety (Taqwa). The exploratory study consists of six intensive interviews, three academics and three practitioners, who were selected from two South-East Asian countries; Malaysia and Indonesia. The respondents represent prestigious academic institutions and top private organizations. The findings from the interviews led to the following propositions that; (1) there is a nexus between OCB and Taqwa; (2) Taqwa and other Islamic principles may serve as antecedents or enabling factors to OCB; and (3) Taqwa should be operationalized for contemporary business research
