Dewetting Rheology for Determining Viscoelastic Properties of Nonequilibrated Thin Polymer Films
(American Chemical Society, 2019)
We performed systematic dewetting experiments on isotactic poly(para-methylstyrene) (iPpMS) films to explore the temperature dependence of the viscoelastic behavior of these films. We quantified the amount of residual ...
Symmetry Dependent Analytical Pseudopotential for Helium Atom
(2019-11-11)
Electron-electron interaction is the origin of the many-body problems usually encountered in physics and chemistry. Helium atom and other two-electron
systems are the simplest many-body systems in nature. The Schr¨odinger ...
Variability of VTEC Gradient and TEC Rate Index Over Kisumu, Kenya During Selected Quiet and Storm Days of 2013 and 2014
(Science Publishing Group, 2019)
Vertical Total electron content (VTEC) gradient or rate of change of TEC (ROT) and total electron content (TEC)
rate index or rate of change of TEC index (ROTI) can directly be estimated from receiver independent exchange ...
Total electron content and scintillations over Maseno, Kenya, during high solar activity year
(Springer International Publishing, 2019)
Proper characterization of total electron content (TEC) and scintillation is very important to global positioning system (GPS) users in communication, navigation, ionospheric or atmospheric studies. Quiet time variation ...
The Acoustic Wave Propagation Equation: Discontinuous Galerkin Time Domain Solution Approach
(Hikari Ltd, 2019)
This paper discusses a finite element method, discontinuous Galerkin
time domain approach that solves the 2-D acoustic wave equation in
cylindrical coordinates. The method is based on discretization of the
wave field ...
Photospins in the quantum Rabi model
(Research gate, 2019)
This article provides a systematic interpretation of the quantum Rabi model as a model of
photospins formed in the atom-field Jaynes-Cummings and anti-Jaynes-Cummings interaction
mechanisms. A photospin is a quantized ...
Effect Of Deposition Temperature On The optical Properties Of Iron-Doped Cadmium Stannate Thin Films Deposited By Spray Pyrolysis
(IJSTRE, 2019)
: Spray Pyrolysis Technique (SPT) was used to deposit thin films (TFs) of cadmium stannate, doped
with iron (Fe) for the first time. The precursor solutions that were used wereprepared at a concentration of
0.1M, doped ...
Role of oxygen concentrations on structural and optical properties of RF magnetron sputtered ZnO thin films
(Springer US, 2019)
We report an investigation on the efect of oxygen fow rate on the structural and optical
properties of zinc oxide thin flms prepared by RF magnetron sputtering. The structural
measurements were carried using grazing ...
Patient Characteristics from an Emergency Care Center in Rural Western Kenya
(Elsevier, 2019)
Emergency care is a neglected area of focus in many low- and middle-income countries. There is a paucity of research on types and frequencies of acute illnesses and injuries in low-resource settings.
The plight of the house-helps (domestic workers) in selected estates in Eastland’s area, Nairobi County, Kenya
(International Journal of Social Sciences, 2019)
In Kenya, households in the middle class suburbs have increasing involvement of house-helps who in most cases take care of household chores. Moreover house helps have borne the brunt of being among the least paid in the ...
