Acceptability of Cereal-Cricket Composite Porridge as Influenced by Socio-Economic Factors and Breast-Feeding Status of Mothers and Care-Givers in Siaya County, Kenya

Abstract The trajectory for widespread integration of edible insects into the human diet is still confronted by low acceptability especially among communities that traditionally or habitually do not consume insects. While the concern today is how best to present edible insects into food matrices that improve their acceptability, this development should be aligned with consumer intrigues into the choices of insect-based foods. This study determined the influence of socio-economic factors (age...

Microbial Community Diversity and Structure within Organic and Conventional Farming Systems in Central Highlands of Kenya

Abstract Microbial diversity and function in agro-ecosystems is influenced by various aspects linked to soil and agronomic practices for example, tillage, irrigation, crop rotation and application of organic and inorganic inputs. Farming systems practices may affect the dynamic interactions existing between soil, plant and microorganisms in different agricultural biomes. Due to limitations associated with conventional microbial cultivation strategies, only a fractional number of cultivable s...

HOUSEHOLD INCOME INEQUALITY AND FOOD INSECURITY IN GHANA

Despite the rise in Ghana’s GDP per capita, food insecurity is still a challenge. Data from the World Income Inequality Database show that the consistent rise in Ghana’s GDP per capita income is accompanied by a rising income inequality trend. The rising income inequality is attributed to rising incomes of only the wealthy classes, leaving more people in economic crises. While several determinants of household food insecurity have been examined, the role of household income inequality is ...

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...
