The purpose of this research was to develop and evaluate pediatric formulation by masking the bitter taste of Isoniazid.Non-compliance of therapy of tuberculosis which is mostly associated with bitter taste can lead to worsening of diseased condition in children. Cationic resin utilized to mask the bitter taste of Isoniazidby preparing resinate complex. Syrup preparation evaluated for drug cont...

Polymer concretes (PCs) were created by using varying concentrations of silica sand as aggregate and also hematite, colemanite and a commercial epoxy resin. Hematite is known to exhibit radiation shielding properties. Mechanical performance was evaluated including unit weight, pulse velocity, compressive strength, flexural strength, splitting tensile strength, modulus of elasticity and dynamic ...

blown bitumen (110/10) was mixed with heavy vacuum slops (h.v.s), 60/70 penetration grade bitumen and recycled isotactic polypropylene (ipp) at different levels. the resulting resins were used to impregnate non-woven poly(ethylene terephthalate) fibers to form composites. the modulus and penetration grade of the resulting bituminous resins were determined. it was found that these bituminous res...

Highly environmentally-friendly fibreboards were manufactured by hot-press moulding using Posidonia ocaeanica wastes and a partially biobased epoxy resin as binder. Fibreboards with a constant fibre content of 70 wt % were successfully manufactured by thermo-compression. The effects of a conventional alkali treatment were compared to the synergistic effects that additional silanization with two...

The production of (82)Sr at iThemba LABS is performed by the proton bombardment of a RbCl target using the facility's Vertical-Beam Target Station (VBTS). (82)Sr is separated from the target material using a method based on target dissolution, using dilute ammonium chloride solution, and the use of chromatographic methods on Purolite S950 ion exchange resin. After performing a further purificat...

Mandarin hybrids were treated with wax and resin coatings having differing oxygen permeabilities. After storage for 7 days at 21 °C, fruit with coatings having O2 permeability 1.1×10 mol m s m Pa were rated by a sensory panel as markedly less fresh than fruit with higher permeability coatings. These low-permeability coatings were those composed mainly of shellac and wood resin. The flavor chang...

An attempt was made to sustain the release of Betahistine hydrochloride by complexation technique using strong cation-exchange resin, Tulsion T344. The drug loading onto ion-exchange resin was optimized for mixing time, activation, effect of pH, swelling time, ratio of drug : resin, and temperature. The resinate was evaluated for micromeritic properties and characterized using XRPD and IR. For ...

The objective of this study was to improve interfacial adhesion properties at the interface of thermomechanical pulp (TMP) fiber and isotactic polypropylene (iPP) using thermoset adhesives such as phenol formaldehyde (PF) and urea formaldehyde (UF). This study also attempted to achieve fiber-to-fiber adhesion using thermoset adhesives before the molten iPP would flow into the fiber web. The fra...

Activated carbon monoliths (ACMs) were fabricated by H2O activation using powdered fast pyrolytic char (PFPC) as a raw material and bio-oil phenol-formaldehyde (BPF) resin as a binder. The effects of the ratio of BPF resin to PFPC on textural and chemical-surface properties of the ACMs were investigated using elemental analysis, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (...

In this paper, a synthesis method of epoxy resin toughening agent was presented, then the chemical composition and molecular number were studied, which include the DSC curves analysis, the fracture surface morphology and bonding strength. In addition, the mechanism of epoxy resin toughening agent and the effect of toughening agent's content to bonding strength were studied. The testing results ...
