Islam and socially responsible business conduct: An empirical research among Dutch entrepreneurs

This paper explores the relationship between the Islamic religion and the level of socially responsible business conduct (SRBC) of Islamic entrepreneurs. We find that the common idea of SRBC corresponds with the view of business in the Islam, although there are also some notable differences. We also find that Muslim entrepreneurs attach a higher weight to specific elements of SRBC than non- Muslims. But, on the other hand, we find that Muslims are less involved with applying SRBC in practice than non-Muslim managers. Furthermore, values and norms derived from the Islamic religion motivate entrepreneurs to contribute more to SRBC and lead to a higher commitment to specific aspects of SRBC compared to individually developed values and norms. Finally, the view of human nature of the Islam, preaching the natural goodness of man as a social being, leads to a positive view of SRBC

Epizootiološko istraživanje slinavke i šapa u Sudanu: stanje nakon dva desetljeća

In order to update information on the situation regarding foot and mouth disease (FMD) in the Sudan, a serosurvey and disease survey were conducted. Recently collected data on FMD in the Sudan showed that FMD is a major constraint to animal production in the country. It presents no threat nor does it cause mild disease in sheep and goats. The disease, with obvious clinical signs, has been detected in cattle only, and is caused by serotype O and SAT 2. Seasonal occurrence of the disease in the cold, dry season has been observed and animal movement seems to play a major role in virus dissemination. A total of 1,069 sera were collected from cattle, sheep, goats, and camel, from seven states in the Sudan, for the detection of antibodies to FMDV. Application of liquid phase blocking (LPB) ELISA revealed that antibodies to four serotypes were present in ruminants; namely O, A, SAT 1 and SAT 2. No antibodies to FMDV were detected in camel sera. The results differed from early reports regarding the prevalence of serotype specifi c antibodies in different species; for instance, in cattle, the antibodies to type A (78.13%) surpassed that of type O (69.39%) and the antibodies to type SAT 2 (44%) surpassed that of type SAT 1 (20.2%). This work elucidates the current epidemiology of FMD in some parts of the Sudan.Radi pružanja informacija o sadašnjem stanju slinavke i šapa u Sudanu provedena su serološka istraživanja te je prikazana njezina pojavnost. Svježe prikupljeni podatci o pojavi slinavke i šapa u Sudanu pokazali su da ona predstavlja veliku prepreku životinjskoj proizvodnji u toj zemlji. U ovaca i koza javlja se kao blaga bolest i ne predstavlja veliku prijetnju, dok se u goveda javlja s očitim kliničkim znakovima, a uzrokovana je serotipovima O i SAT 2. Bolest se javlja sezonski u hladnoj i suhoj sezoni, a promet životinjama ima glavnu ulogu u širenju virusa. Ukupno je bilo prikupljeno 1069 uzoraka seruma goveda, ovaca, koza i deva podrijetlom iz sedam država u Sudanu radi pretrage na prisutnost protutijela za virus slinavke i šapa. Blokirajućim imunonenzimnim testom dokazana su protutijela za četiri serotipa virusa: O, A, SAT 1 i SAT 2. Protutijela za virus slinavke i šapa nisu bila dokazana u uzorcima seruma deva. Rezultati se razlikuju od ranijih izvješća s obzirom na prevalenciju specifi čnih protutijela u različitih vrsta. Npr., specifi čna protutijela za serotip A dokazana su u 78,13% goveda, za serotip O u 69,39%, serotip SAT 2 u 44% te serotip SAT 1 u 20,2% goveda. U radu je prikazano sadašnje epizootiološko stanje slinavke i šapa u nekim dijelovima Sudana

Large Amplitude Pitching of Supermaneuver Delta Wings Including Flow Control

The unsteady, three-dimensional Navier-Stokes equations are solved to simulate and study the aerodynamic response of a delta wing undergoing large amplitude pitching motion up to 90° angle of attack. The primary model under consideration consists of a 76° swept, sharp-edged delta wing of zero thickness, initially at zero angle of attack. The freestream Mach number and Reynolds number are 0.3 and 0.45 × 106, respectively. The governing equations are solved time-accurately using the implicit, upwind, Roe flux-difference splitting, finite-volume scheme. Both laminar and turbulent flow solutions are investigated. In the laminar flow solutions, validation of the computational results is carried out using existing experimental data, and shows good agreement. The effect of reduced frequency of the wing motion is then presented and a grid refinement study is introduced. In the turbulent flow simulations, both Baldwin-Lomax and Spalart-Allmaras turbulence models are used and the results are compared with those of the laminar solution and experimental data as well. A sinusoidal pitching motion of the wing is also investigated in the present work. The computational results provide complete information and details about the flowfield response, which are difficult to obtain from experiment. A feasibility study of using one of the flow control techniques, blowing, to enhance maneuverability is introduced. The investigation of the unsteady flow over a wide range of angles of attack provides crucial understanding of the variations of the leading edge vortex cores, their breakdown behavior, aerodynamic hysteresis, and wing aerodynamic characteristics at very high angle of attack. The current study shows that numerical simulations in the very high angle of attack range are obtainable. Such calculations were thought to be unattainable as recently as the 1980\u27s

ANTI-BACTERIAL EFFECTS OF GLYCOSIDES EXTRACT OF GLYCYRRHIZA GLABRA L. FROM THE REGION OF DJAMÂA (SOUTH-EAST OF ALGERIA)

The natural extracts of plants contain a variety of biologically active molecules. In this context, we attempted to evaluate the antimicrobial activity of some extracts prepared from the root of Glycyrrhiza glabra L., which grows in the region of Djamâa (south of Algeria). The qualitative analysis of these extracts revealed the presence of plant glycosides, which is confirmed by a quantitative analysis based on the detection test of glycosides, who demonstrated that the extracts are rich in these molecules, where the content of glycoside reached (10 %) for the ethanol extraction. The evaluation of the glycoside extract antimicrobial activity revealed a strong effect of inhibition on different strain of bacteria, when it was responsible for a large zone of inhibition of the bacterial strain Pseudomonas aeruginosa, compared to Escherichia coli and staphylococcus aureus. From these results, we can say that the glycoside extracts have different antibacterial effects depending on the species
