We explore the possibility for elemental analysis by NMR. To keep the efficiency of the signal acquisition common for all spin species, we propose to fix the frequency and vary the magnetic field to cover the isotopes involved in a sample. We introduce constant-frequency receptivity for quantitative elemental analysis in the frequency-fixed NMR experiment. Field-variable NMR experiments are dem...

Scorpion venom is a rich source of biomolecules, which can perturb physiological activity of the host on envenomation and may also have a therapeutic potential. Scorpion venoms produced by the columnar cells of venom gland are complex mixture of mucopolysaccharides, neurotoxic peptides and other components. This study was aimed at cataloguing the elemental composition of venoms obtained from me...

resistant version of the standard Zymark arm was chosen for this project. A special problem was posed, however, in the handling of these solutions in the volumes required (10-300 mL) without contaminating the delivery devices. A solution was found through the use of peristaltic pumps and three-way pinch valves. These components were assembled into a pump station controlled by digital signals fr...

To many in our community the study of nuclear Physics is a mental exercise that strengthens the mind, and helps to accumulate the appropriate number of points for a BSc degree. In reality many of the fundamental concepts of Physics, and nuclear physics in particular, have led to significant improvements in the community. (ref. MRI, CAT, PET, radiation therapy, nuclear power). This paper address...

Introduction Commercial production of large-area silicon drift detectors (SDDs) heralds an exciting new time in biological elemental analysis. Improved low-energy performance and higher collection efficiencies mean EDS is no longer limited by low count rates and poor solid angles. High count rates can be achieved on all types of materials, including soft biological tissues, without altering nor...

Purpose: This research was conducted with the aim of studying the essential components of curriculum social education in the elementary period. Methodology: The statistical population of the study included upstream documents such as the Transformation Document and the National Curriculum, both fully analyzed and analyzed. The statistical population and the statistical sample are equal in this r...

Acacia nilotica (Thorn mimosa) is used locally for various medicinal purposes by traditionalists and herbalists in northeastern Nigeria. Plants products have been used since ancient times in the management of various conditions. The bark of A. nilotica has been reported to be used traditionally to manage diabetes, dysentery, leprosy, ulcers, cancers, tumor of the eye, ear and ...

Background and objectives: Tapinanthus globifer is a semi-parasite plant that mostly grows on the branches of the host tree species of the genera Vitellaria, Kola, Citrus, Combretum, Acacia, and Terminalia. The leaf is known for its use in traditional medicine to treat inflammations, malaria, headaches, bacterial infections, ulcers and diabet...
