Modeling and Forecasting Inflation in Ethiopia Using Multivariate Time Series Analysis

Inflation is one of the basic indicators of macroeconomic stability, influences numerous other macroeconomic factors and it debilitates the economy of the country. Thus, in this study, the major objective was based on modelling and forecast inflation in Ethiopia and its components using a VAR model. all five series exhibited an increasing pattern, indicating non-stationarity in each of the series. The analysis was based on annually data from 1992 to 2021, encompassing 30 years. The results in...

Lipid Stability in Soy Flours Produced From Raw and Processed Soybeans

ABSTRACT Soybean, a high protein/oil legume is known to contain high levels of polyunsaturated fatty acids, which are susceptible to lipid oxidation and hydrolysis. However, suitable processing methods and storage conditions can enhance the stability of lipids in soy flour. The objective of the project was to investigate the effects of some processing methods and storage conditions on the stability of lipids in soy flour and to define the parameters for the prediction of the shelf life of soy...

The study is quantitative using cross-sectional and survey research techniques. The research analysed data from 467 lactating mothers in Gusau metropolis employing snowballing sampling technique. Data were analysed using Statis...

QUALITATIVE PHYTOCHEMICAL SCREENING AND PERCENTAGE YIELD OF MORINGA OLEIFERA LEAVES EXTRACT IN SOLVENTS OF DIFFERENT POLARITY.

Plants have been known to be used in the treatment and management of diseases, and this is due to the presence of phytochemicals. Thus, the screening of plants qualitatively, has got the interest of researchers. Moringa Oleifera is a fast growing deciduous tree with its different plant parts commonly used in herbal medicine, also with good socio-economic and industrial values. In this study qualitative photochemical screening was carried on Moringa oleifera leaves extract to test for alkal...

Assessment of Polycyclic Aromatic Hydrocarbons (PAHs) in Charcoal Production Areas in Nasarawa State

Wood charcoal is the most important means of human exposure to Polycyclic Aromatic Hydrocarbons (PAHs). The Polycyclic Aromatic Hydrocarbons (PAHs) were observed in soil sample and charcoal is the major source of human exposure to PAHs. In the present study, the PAHs concentrations were determined using gas Chromatograph/Mass Spectrometer (GC/MS), and the results showed that all the PAHs analyzed were below and above detection limits of the equipment; and these were considered to present l...

A COMPARATIVE STUDY OF THE NUTRITIONAL QUALITY OF FRESHLY EXTRACTED JUICES FROM ORGANIC VERSUS CONVENTIONAL ORANGE AND APPLE FRUITS

ABSTRACT Freshly extracted juices obtained from organically and conventionally produced orange and apple fruits were assayed in terms of their nutritional quality. Parameters used in the assessment were total soluble sugars, ascorbic acid content, folic acid concentration, acidity, glucose, fructose, maltose and sucrose contents, as well as the concentrations of sodium, potassium, calcium, iron, zinc and copper. Total and individual sugars were detected using HPLC while brix concentrations we...

Assessing the reliability and accuracy of sex estimation models utilizing sternal morphometry derived from computed tomography in the Ghanaian population

Sex estimation models are specific to populations and cannot be generalized due to genetic and environmental variabilities. This retrospective cross-sectional study, conducted between January and September 2023 at the Tamale Teaching Hospital, included 119 (50.9 %) females and 115 (49.1 %) males aged 23–82 years. Measurements, including manubrium length (M), manubrium width (MW), sternal body length (B), combined manubrium and sternal body lengths (CL), corpus sterni width at first sternebr...

Magnetoelectric, dielectric, and magnetic investigations of multiferroic NixCo1-xFe2O4-SryBa1-yNb2O6 composites

Magnetoelectric (NixCo1-xFe2O4)0.3-(SryBa1-yNb2O6)0.7 composites with a 0–3 connectivity and different cation stoichiometries were synthesized via a classical mixed-oxide method. XRD patterns of all ceramics show reflections of the target phases SryBa1-yNb2O6 and NixCo1-xFe2O4. The influence of stoichiometry of the ferrimagnetic and ferroelectric phase on the magnetoelectric behavior was studied on composites with composition of (NixCo1-xFe2O4)0.3-(Sr0.5Ba0.5Nb2O6)0.7 and (NiFe2O4)0.3-(SryB...

Intraspecific and interspecific olfactory interactions and density of leopards Panthera pardus (Linnaeus, 1758) in Sabi Sands Game Reserve, South Africa

Abstract: The olfactory behavioural ecology of large solitary carnivores is still poorly understood. Meanwhile, these species represent challenging cases in conservation and management. They are frequently involved in conflicts with farmers, depredating livestock and being killed in retaliation. Low densities and large territories also make it hard to assess their population status accurately. This thesis aimed to improve our understanding of the African leopard (Panthera pardus) olfactory e...

Geology and economic mineralization of the neoproterozoic Mozambique belt rocks of the Mwitika-Makongo area, Kitui County, South Eastern Kenya

Abstract: The Mwitika-Makongo research area occurs within the Neoproterozoic Mozambique metamorphic belt in Kenya and is located in Kitui East sub-county of Kitui County. The area is bounded by longitudes 38° 18'E and 38° 26'E and latitudes 1° 22'S and 1° 32'S. This area is easily accessed from the Nairobi-Thika-Kitui-Zombe road or the Nairobi –Machakos-Kitui-Zombe road. From previous geological works, it had been established that several mineral resources of economic potential like ir...

An assessment of demographic parameters of African rhinoceros species (Diceros bicornis and Ceratotherium simum) and their significance to management in captivity

Abstract: Captive-breeding has been identified as an integral part of the conservation of threatened species. The black rhinoceros (Diceros bicornis) as a species is currently listed by the IUCN as critically endangered (CR), while the white rhinoceros’s (Ceratotherium simum) current status is near-threatened (NT). Three African rhinoceros subspecies currently occur in captive populations in regional population management programmes, namely the South-central black rhinoceros (Diceros bicor...

Understanding current and potential distribution of Australian acacia species in southern Africa

Abstract: This dissertation presents research on the value of using different sources of data to explore the factors determining invasiveness of introduced species. The research draws upon the availability of data on the historical trial plantings of alien species and other sources. The focus of the study is on Australian Acacia species as a taxon introduced into southern Africa (Lesotho, South Africa and Swaziland). The first component of the study focused on understanding the factors deter...

Impacts of a specialist diet on aardwolf ecology

Abstract: The diet of an animal plays a fundamental role in its ecology, and the consequence of a specific diet may be more pronounced in mammals with a specialised diet that are more reliant on a specific food type. This can have a dramatic effect on its activity patterns, home range size and the interaction with heterospecifics. Investigating the diet of specialist mammals and the subsequent effects it will have on their ecology is thus vital to the management and subsequent conservation o...

Population structure and predation in the harvester termite, Trinervitermes trinervoides

Abstract: Little information is available on the termite species in southern Africa, especially Trinervitermes trinervoides (Sjöstedt). This is an endemic, non-detrimental harvester termite that performs vital ecosystem functions in the semi-arid grassland ecosystem of southern Africa. T. trinervoides is the only termite species that does not compete with grazers for foraging material since they harvest litter grass. T. trinervoides are highly eusocial, mound-building, nasute termites. The ...
