Measurements of the differential cross sections for the He(y, n) He and He(y, p)3H reactions have been performed for photon energies in the 100 — 360 MeU region. Results were obtained for nucleon center-of-mass angles close to 60', 90', and 120' by detecting the recoiling nuclei with a magnetic spectrometer. Both (y,p) and (y,n) cross sections are forward peaked and fall rapidly as a function o...

Simple but reliable methods for the determination of the physicochemical properties of gari were evaluated for the parameters, such as grain size, bulk density, swelling index, moisture content, gross calorific value, cyanide content, and acidity content. The grain sizes were between 525 and 928 μm (weighted means), the bulk densities between 0.541 and 0.699 g/cm³, and the swelling indices betw...

This study evaluated the distribution of particulates (PM1, PM 2.5, 4, 7, 10, and TSP) around smallholder gari production facilities in Niger Delta, Nigeria. The were at 3 distances (3.05, 7.62, 15.24 m) from emission source dry season (November, January, March) wet (May, July, September) Bayelsa, Rivers, Abia states. A mini-volume air sampler was used to assess concentration particulates, whil...

have been made in field olfactometers with brevicomin, which was identified in the frass of female D. brevicomis (6). The material has consistently given indifferent results or been totally ineffective. However, when a representative assortment of natural terpenes was tested in conjunction with brevicomin, 3-carene proved to be effective in activating the substance. 3-Carene was superior to myr...

Conditions within the Homunculus nebula around Eta Car are determined by many of the same physical processes that occur in molecular clouds in the interstellar medium. But there is one major exception – we know when the ejection occurred and something about its composition and initial state. The gas was warm, ionized, and dust-free when it was located within the star’s atmosphere and it is curr...

This paper proposes modifications to the popular model of equilibrium unemployment by Mortensen and Pissarides [30]. I augment the model by introducing (1) costly planning for brand-new jobs, (2) the option to mothball preexisting jobs, and (3) a non-trivial job rejection decision for new employment relationships. These modifications greatly improve the model’s ability to replicate the Beveridg...

In many parts of West Africa, there is generally an inadequate supply foods that are rich in nutrients needed by the human body for health and productive life. The purpose this study to assess nutritional content fruit juices distributed Sabon Gari, Zaria market; pH level, sodium chloride equivalent (Salt content), acid content, total dissolved solids electrical conductivity ten (10) different ...
