ABSTRACT Concentrations of 16 priority polycyclic Aromatic Hydrocarbons (PAHs) were determined in 30 brands of Nigerian and imported pastas in Nigerian market. The pasta samples were categorised into (1) noodles (2) spaghetti and (3) macaroni. Analysis were performed by GC – MS after soxhlet extraction of the sample and clean up of the extract. The concentration of Σ16 PAHs in both the Nigerian and imported brands are in the range of 0.009 to 0.8 mgkg-1 and 0.002 to 0.007 mgkg-1 respectiv...
ABSTRACT Human breast milk is universally recognized as the optimal food for term infants. Fatty acids play important roles in biological systems and the newborn’s fatty acid requirements are wholly met by the mothers’ breast milk. Although there have been many studies on fatty acid composition of human milk from Western countries and Africa, there is little information about that in the Kenyan population. This study was conducted to characterize and analyze quantitatively the fatty acid ...
ABSTRACT Cadmium (Cd) is a ubiquitous environmental and industrial pollutantwhose exact toxicity mechanisms still remain elusive. However, cumulative data has implicated bioaccumulation as well as free radical generation in the biochemical and molecular mechanisms of cadmium induced toxicity. Chelation therapy with calcium disodium ethylenediamine tetra acetic acid (CaNa2EDTA), British Anti Lewisite (BAL), meso 2, 3-dimercaptosuccinic acid (DMSA) is so far among the best known treatment again...

ABSTRACT An epidemiological study was carried out between September 2011 and February 2012 to determine the disease status of Peste des Petits ruminants (PPR) in western Kigoma region bordering Burundi and Democratic Republic of Congo (DRC). The study aimed at establishing the seroprevalence of PPR and identifying risk factors associated with the disease in three districts (Kasulu, Kibondo and Kigoma rural) of Kigoma region. The study also assessed the presence or absence of clinical cases i...
Complexing capacities of calcium and magnesium with natural organic matter (NOM)/selected organic chelating agents, in the presence and absence of other major and trace cations in water, were studied by anodic and cathodic square wave stripping voltammetry techniques (ASWSV and CSWSV). Under predetermined and optimized physico-chemical parameters (pH, temperature and ionic strength), calcium-NOM complexation and competitive complexation by other elements of known concentration (Pb, Zn, a...
This thesis is concerned with exploring alternative conceptualizations of the e-government artifact relevant to developing countries in Africa. The premise is that e-government, as an artifact of human conception, remains relatively poorly developed at the levels of theory, methodologies and practice. The investigation is focused on two problematic areas of e-government: its conceptualization and its operationalization as an artifact. There is evidence to suggest that conceptualization of...
This study was conducted to estimate serum fructosamine and HbA1c in patients with type 1 and type 2 DM. 100 blood samples (50 type 1, 50 type 2) were collected from patients during period from February to April 2016, chosen randomly from health insurance – diabetic center and El-obied teaching hospital, and 50 apparently healthy individuals as control group to evaluate and estimate serum fructosamine and HbA1c in diabetic patients. Nitroblue tetrazolium method used to estimate serum ...
We study the operator commuting and essential commutant of analytic Toeplitz operators module the compact operators and Toeplitz operators in several complex variables and on the Bergman space of the until ball. We show the ordered groups and some exact sequences and the commutator ideal of the Toeplitz algebras of spherical isometries and on the Bergman spaces of the unit ball in the unitary space. We give the lower bounds in the matrix, new estimate for the vector-valued and matrix-va...
In this research we studied the global warming by knowing the definition, and the causes. This research covers the Earth's atmosphere in details and the gases in each layer. Also the physical properties (pressure, thickness, temperature, speed of sound, density, mass), optical properties (scattering, absorption, emission, refractive index). Other aspects such as the Industrial Revolution and its role in the increase of greenhouse gases, the study covers United States of America, and Chi...
ABSTRACT The rapid increase of smartphone proliferation in Kenya has resulted in users being dependent on their phones for everyday activities. This increased interaction with smartphones has posed a significant threat to users’ privacy and security. The exposure to threats demonstrates a need to understand users’ security awareness and behavior when using their mobile phones. Therefore, this study sought to establish the level of security risk awareness and user behaviour among smartpho...
Phytochemical investigation of fruit pulp of Adansonia digitata gave positive reactions for : steroids,terpenes,flavonoids,tannins and glycosides. GC-MS analysis of Adansonia digitataoil was conducted and the identification of the constituents was initially accomplished by comparison with the MS library (NIST) and further confirmed by interpreting of the observed fragmentation pattern.Comparison of the mass spectra with the database on MS library revealed about 90-95% match. The GC-M...
This study was conducted to establish reference values for some biochemical parameters of synovial fluid in Sudanese cattle and to compare them with the corresponding values in serum, also to establish the correlation and regression among serum and synovial fluid parameters. The bulls were selected from the herd of the Animal Production Research Centre- Khartoum North- Hilat kuku, from January 2018 to October 2019. Eleven blood samples and twenty two synovial fluid samples were collecte...
Dealt with the subject of the study through spatial distribution of the governmental health centers, for understanding its relationship with the numbersof population, health outcomes and access, in light of rapid urbanization worldwide. The crisis in the health sector of Sudan has seen very obvious since the last decade, particularly in Bahri locality. It turns out the requires of appropriate infrastructure because of lack of attention to proper and suitable planning for the distribut...
This study comprises the synthesis and spectral properties of three chalcones 3-(4-n (dimethylamino)phenyl)-1-phenyl-(2E)-propen-1-one (DMAPPP),1-(4-methylphenyl)- 3-(4- N, N-dimethyl amino phenyl)-2-propen-1-one (MDMAPP) and 1-(4- chloridephenyl)-3-(4- N, N dimethyl amino phenyl)-2-propen-1-one (CPDAPP) in several organic solvents have been studied.
