ABSTRACT The quest to boost dietary protein production from readily available and affordable sources is ever increasing in developing countries. The indigenous edible Pleurotus species (oyster mushrooms), which grow naturally on wood wastes, are potential protein supplements. However, little information is available on the usage of selected tropical trees for optimum mushroom cultivation. Therefore, this research was designed to investigate the growth and yield of oyster mushrooms on sawdust...
Physicochemical properties of Acacia Senegal var Senegal gum purified by foaming and processed gum (ELNsr) samples were studied. The results showed that the moisture content, ash, nitrogen, protein, viscosity, specific optical rotation and pH were (10.74% and 10.86%), (3.84% and 3.55%), (0.25% and 0.27%), (2.35% and 2.30%), (14.5 cm3g-1 and 14.8 cm 3g-1 ), (-33.61° and -30.75°) and (4.9 and 4.5)] respectively. The gum produced by foaming consists of arabinose (33%), rhamnose (13.5...
The objective of this research is to use computational chemistry through the study of three heterocyclic compounds of 1,3,4-oxidizole derivatives. Quantum chemical calculations based on density function theory (DFT) method were performed on three nitrogen-bearing heterocyclic compounds used as corrosion inhibitors for the mild steel in acid media to determine the relationship between the molecular structure of inhibitors and inhibition efficiency. The structural parameters, such as ener...
Background CRP was the first acute phase protein to be described and is sensitive systemic marker of inflammation and tissue damage especially in liver disease . hepatitis B viruses Is a common health problem throughout the world and one of the major risk factors for liver disease. General objective: To assess High Sensitive C-reactive protien of Hepatitis B in sudanese Patients In Khartoum State. Specific Objective: To assess CRP levels an study Group To correlate between C...
In this study, phenolic compounds were extracted from roots of Balanites aegyptiaca, seeds of Hagenia abyssinica and roots of Cisuss petiolata using 95% ethanol. The crude ethanolic extracts of the studied species were subjected to paper chromatography. In this way compound I was isolated from the roots of Balanites aegyptiaca. The structure of this isolate was elucidated by a combination of spectral techniques (UV, IR, NMR and MS) and the following tentative structure was proposed:
ABSTRACT Rapid and accurate diagnosis is paramount in understanding the infection status of foot and-mouth disease (FMD) virus (FMDV) in animals. In this study, the singleplex real time RT-PCR (qRT-PCR) assay employing the Callahan 3DF-2, 3DF-R primers and Callahan 3DP-1 probe were used in screening for FMDV genome on esophageal– pharyngeal (OP) fluids. The OP samples were collected from cattle and African buffaloes in livestock-wildlife interface areas of Mikumi, Mkomazi and Ruaha Nationa...
In this dissertation, we derived the Renormalization Group Equations (RGEs) for five dimensional Minimal Super-symmetric Standard Model (MSSM) plus additional fields . We found a successful unification of gauge coupling constants in this model very close to: GeV. Yukawa couplings seemed to be tending to unify at some high scale and approximately vanish beyond the unification scale of the gauge couplings, i.e. GeV. We showed that a five dimensional (5D) MSSM with compactification scale o...
The aim of the present study was to investigate the effect of extraction methods on the thermal properties and the antimicrobial activity of Moringa peregrina seeds oil. The oil was extracted by cold pressing (CP) and maceration in n hexane (MH). The yields of the oils were 9.12% % and 21.87% respectively. Except the peroxide value, the chemical properties of the oil extracted by the two methods remained fairly unchanged. Additionally, the results have revealed that the oil which was ex...
Twistor theory has been invented by R. Penrose in order to generalize gravity. He introduced a geometrical model for Minkowski space. This geometrical setup has been generalized in solving particle differential equations. In particular zero-rest-mass field equation have been treated this way as a Contour integral of complex twistor function. In our study we consider geometrical interpretations and solutions of conformal field equations. We also studied Twistors in curved space-time and ...
Cloud computing refers to both the applications delivered as services over the Internet and the system hardware and software that provide these services. The service itself is referred to as Software as a Service (SaaS). Various cloud providers are now available. These providers offer different cloud services to their enterprise. Balance between Performances and cost of service is a crucial aspect of cloud service. Cloud services from different providers have different cost and performan...
ABSTRACT Infectious bursal disease (IBD) is a highly contagious disease of young chickens between 3 and 6 weeks of age. It is caused by infectious bursal disease virus(IBDV) which occursworldwide affecting livelihoods of resource - compromised poor communities. In Zambia, there is scantily documented information on the epidemiology of IBD. In-depth knowledge on the epidemiology of IBD is needed for effective control measures. This study aimed at molecular detection of circulating IBDV strain...
ABSTRACT The development of resistance to insecticides by Anopheles mosquitoes continues to threaten the success of malaria control programmes in West Africa. Local data on mechanisms and factors causing resistance in the region are scanty. This study was designed to investigate the environmental factors and mechanisms implicated in resistance to pyrethroids by Anopheles gambiae in southwestern Nigeria and southern Benin Republic. Larvae of Anopheles mosquito were collected in 2007 from...
ABSTRACT Mosquito-borne viruses primarily infect animals and humans causing significant public and veterinary health threat. Transmitted by hematophagous mosquitoes, dengue virus and Rift Valley fever virus are the most common outbreaks that occurred in parts of Tanzania especially in malaria endemic areas. Several studies reported the presence of the viruses in circulation in animals and humans. Therefore, this study sought to investigate the diversity of mosquito-borne virus vectors and to...
ABSTRACT Sardines in Tanzania are small pelagic fish eaten in a dried form mainly by the poor and middle-income groups. The main objective of this research was to assess the influence of postharvest handling of sardines from Lake Victoria and its effects on the quality and sensory attributes of the final product. Cross-sectional and factorial designs were used to collect data for field survey and laboratory analyses, respectively. Ninety three respondents were involved in the survey to asses...
