  • Mapping Rangeland Degradation by using Rainfall and Remote Sensing Data,
Abstract climate factors in conjunction with Satellite imagery and aerial photographs provides an opportunity to undertake routine natural resources monitoring for mapping land degradation over a large area such as pasture land and over a long time period. These facilities provide efficient decision making for resources management and implementation of the control measures. To explore the climate change in terms of rainfall and their impact on the rangeland conditions in north-eastern part of Sudan, the annual time series (1940 to 2004) for two weather stations across the area were analyzed. Aerial photographs for three selected sites in the study area were used to produce maps using grey tone, drainage pattern, vegetation cover and land use. These maps were overlaid with the Landsat images for 2000 to map the land degradation. The analysis of the rainfall data showed a significant decrease in annual rainfall during period 1940 to 2004. From remote sensing data the map showed that during the 1960s there was active rain-fed agriculture and dense trees and bare soil in the area. When these maps were overlaid with Landsat 2000 it can be noticed that the eroded and bare soil area increased considerably and there were some areas covered with grass which was an indication of bush encroachment. From the results it can be noticed that the different ecosystems in the area were subjected to various forms of site degradation. These have led to sand encroachment and increased the water erosion in the northern part of the area. But in many parts the degradation is still reversible if organized control measures introduced

Abstract:   

Methicillin sensitive and resistance Staphylococcus aureus infections were increased dramatically in Sudan in the few last years, both in community and hospital settings. This was attributed to the irrational use of antibiotics which caused a major raise in the mortality and morbidity rates. The objective of this research was to evaluate the anti-Bacterial activity of Minocycline against clinically isolated Methicillin sensitive Staphylococcus aureus (MSSA) and Methicillin resistance Staphylococcus aureus (MRSA), where the activity was compared to Vancomycin, Ciprofloxacin, and Gentamicin. The study followed a standardized In vitro microbiological assay techniques included well diffusion technique and broth dilution assays to determine the clear zone of inhibitions and minimum inhibitory concentration (MIC) respectively, for the previously mentioned antibiotics. Although Vancomycin is used as a first line of therapy in the treatment of MRSA infections, but Minocycline was found to be more active against both MRSA and MSSA than Vancomycin. Ciprofloxacin had a relatively good spectrum of activity against MRSA in addition to its well-known activity against MSSA thus, it should be considered as a good treatment option for MRSA and MSSA. Minocycline showed lower activity against MRSA and MSSA when it was compared to ciprofloxacin. Furthermore, MRSA and MSSA showed the highest resistance pattern against vancomycin compared with other antimicrobial agents. Therefore, Minocycline worth to be encouraged with In vivo tests and to be illustrated for registration by health authorities in Sudan for future use in the treatment of MSSA and MRSA infections.

  • Sustainable Production of Maize (Zea mays L.) in Sudan Achieve Cost Reduction of Poultry Production

The main objective of this research is to investigate the effect of chemical fertilizer, organic fertilizer and a combination of both treatments on maize (Zea mays L.) production and yield for sustainability in Sudan.  Three levels of fertilizer: 86 Kg.N/ha. ,4  ton chicken manure /ha. and a combination of 43 Kg. N/ha. + 2-ton chicken manure /ha, were applied on cultivar Mogtama 45. Field experiments were conducted for two consecutive seasons; 2010/11 and 2011/12, at the Experimental farm, Faculty of Agricultural sciences, University of Gezira, Wad Medani, Gezira State (Sudan). The results showed that maximum plant population and yield were obtained on application of combination of the two types of fertilizers in both seasons. In addition, the highest values of plant height, head weight, 100-seed weight and grain yield were obtained. These results confirmed that the prospects of sustainable maize production in Sudan are high. Moreover, as sorghum is a key element in poultry feed, a spillover effect on cost reduction of poultry production could have a positive impact on poultry production.
