Therefore, this study was conducted to asses morpho-agronomic variations in the lowland rice genotypes in an Alpha lattice design with three replications. The experiment was conducted at National Cereals Research Institute Badeggi and Edozhigi in 2017. Parameters such as Days to 50 % ...

ABSTRACT Protein energy malnutrition (PEM) accounts for over 50 % mortality among weaning children globally. Fortification and formulation had been used to supply some of the nutritionally deficient nutrients in diets of malnourished children. Sorghum is generally used as weaning foods in developing countries but is deficient in protein while Bambara nut is rich in protein and can provide the nutrients lacking in sorghum. This study focused on the effect ...

ABSTRACT Value Management (VM) has played a broad role in supporting effective decision making on construction projects, increased project performance and quality, balance project objectives, and manage community expectations in many countries around the world. But applicability of VM in Nigeria construction industry has experienced setbacks compared with rest of the world. It is on this basis that the study examined the factors responsible for the setbacks with a view ...

ABSTRACT Biophilic architecture is based on the assertion that humans have an innate connection with nature that should be expressed in their daily lives, especially in cities. This, which has not been a strong feature of architectural principles (even though there has been a long tradition of landscape architecture), yet potentially offers great rewards if the assertion is true. However, earlier and more recent studies have revealed that individuals who ...

ABSTRACT Concrete is a combination of cement, fine and coarse aggregates and water, which are mixed in a particular proportion to arrive at a particular strength. The cement and water react together chemically to form a paste together with the aggregate particles. The mixture sets into a rock-like solid mass, which has considerable compressive strength but little resistance in tension. In this research, concrete was properly mixed using salt water ...
