dosulepin and doxepin are tricyclic antidepressants. the molecular geometries, harmonic vibrational frequencies, quantum chemical parameters and thermodynamic properties of dosulepin and doxepin were calculated by generalized gradient approximation methods developed by perdew and wang (gga-pw91) and becke-lee-yang-parr (gga-blyp) in the gas phase and solution media. the local reactivity of thes...

Plasmas have a broad field of applications, such as air-breathing hypersonic vehicles (plasma control for scramjet engine), spacecraft atmospheric entries (influence of precursor electrons and prediction of blackout phenomenon), high-enthalpy wind tunnels (plasmatron, arc-jet, and shock tube facilities), lightning phenomena, discharges at atmospheric pressure, laboratory nuclear fusion and astr...

BACKGROUND Uganda's banana industry is heavily impeded by the lack of cheap, reliable and sustainable energy mainly needed for processing of banana fruit into pulp and subsequent drying into chips before milling into banana flour that has several uses in the bakery industry, among others. Uganda has one of the lowest electricity access levels, estimated at only 2-3% in rural areas where most of...

Headspace solid-phase microextraction was used to extract low-molecular mass degradation products formed during thermo-oxidation of virgin and inplant recycled polyamide 6.6 at 100°C for up to 1200 hours. A total of 20 degradation products were identified using GC-MS. The identified degradation products shared some common structural features and were categorised into four different groups: cycl...

Biomass materials are being investigated and utilized in an ever-widening sphere of industrial scale applications. As this realm of utilization expands, fundamental knowledge of potential feedstocks becomes paramount. This study was undertaken to observe the chemical composition and thermogravimetric behavior of one set of biomass materials. This set includes fibers or ground portions of: corn ...

An analytical study was performed to study effects of thermo-diffusion and chemical reactions on a three-dimensional MHD mixed convective flow of dissipative fluid along an infinite vertical porous plate with transverse sinusoidal suction velocity. The parabolic partial differential equations governing the fluid flow, heat transfer, and mass transfer were solved using perturbation technique and...

In this study, by using the finite volume method, the heat transfer in a convective straight fin with temperature-dependent thermal properties and an internal heat generation under multi-boiling heat transfer modes are analyzed. In this regard, the local heat transfer coefficient is considered to vary within a power-law function of temperature. In the present study, the coexistence of all the b...

Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...
