In terahertz (THz) and far-infrared (FIR) spectroscopic measurements, weak absorption spectral features due to small quantities of test sample can be masked by undesirable etalon fringe artifacts caused by multiple reflections within a pellet or a rigid sample holder. A double-layered nitrocellulose (NC) membrane structure is proposed in this paper as an alternative holder for small quantities ...

the uncontrolled spread of illegal artisanal small-scale gold mining (asm), popularly termed “galamsey” in ghana, has, for decades, impacted adversely upon water bodies, soils, wildlife, human health, and safety. a lack of understanding, however, of the types of galamsey, their operational attributes, and their relative impacts has unfortunately hindered an effective policy response despite num...

in this research, the bending analysis of rectangular nanoplates subjected to mechanical loading is investigated. for this purpose, the strain gradient elasticity theory with one gradient parameter is presented to study the nanoplates. from the best knowledge of authors, it is the first time that the exponential shear deformation formulation based on strain gradient elasticity theory is carried...

this study had the objective of determining the fertility and calving ease of small holder indigenous cattle herds inseminated with imported semen from proven sires. sixty one indigenous cows of different breed origin (bunaji, sokoto gudali and rahaji) were selected from different herds across jigawa state-nigeria, and were used for this study. the selected dams were inseminated with semen from...

A FAMILY of inequalities concerning inner products of vectors and functions began with Cauchy. The extensions and generalizations later led to the inequalities of Schwarz, Minkowski and Holder. The well known Holder inequality involves the inner product of vectors measured by Minkowski norms. In this paper, another step of extension is taken so that a Holder type inequality may apply to general...

Farmers can only be market oriented if his/her production plan follows market signals and produce commodities that is more marketable. In other to achieve this, this study provided empirical evidence on the Gender analyses of market orientation in South Eastern, Nigeria. A stratified sampling design was used to select 360 sample respondents in 2017. Market Orientation Index (MOI) and Heckit sel...

Currently, Sub-Sahara is experiencing increased frequency of disasters either as floods or droughts which diverts scarce resources, time and efforts from other sustainable millennium development goals. Success in preventing food shortages in African continent will only be achieved if we understand the vulnerability and risk of the majority of small-holder farmers under rainfed and supplemental ...

Potential and constraints of employing agricultural biotechnology as a development tool: GMo cultivation and small-holder farmers in dharmapuri district, India drawing on the case of dharmapuri district, south India, the article aims to investigate the potential and the constraints by which agricultural biotechnologies can be employed to serve the purpose of agricultural and rural development. ...

A new approach to sample handling for powder X-ray diffraction analysis is presented that allows characterization of poorly prepared samples. The technique relies on vibrations generated in a sample holder to create movement of the powdered sample in the absence of macroscopic movement of the sample holder itself. The major benefits over conventional sample handling strategies are: 1) the abili...
