Aim. To investigate (a) variability in powder/liquid proportioning and (b) effect of variability on diametral tensile strength (DTS), in a zinc phosphate cement. Statistical analyses (α = 0.05) were by Student's t-test in the case of powder/liquid ratio and one-way ANOVA and Tukey HSD for pair-wise comparisons of mean DTS. The Null hypotheses were that (a) the powder-liquid mixing ratios would ...

Entostat is an electrostatically charged wax powder that can adhere strongly to insect cuticle, making it an ideal carrier to deliver pheromone for pheromone-based confusion techniques. We investigated the attractiveness of Cydia pomonella (L.) (Lepidoptera: Tortricidae) males treated with pheromone-laden Entostat powder to naive conspecifics as well as mating behaviors of males after such trea...

Elemental powder mixes were subjected to plane-wave shock processing which reduced the initial porosity to essentially zero. Two powder mixes in a 5:3 Ti:Si atomic ratio were used: 2325 mesh Ti and Si ~,45 mm!, and 2100 mesh Ti and Si ~,150 mm! with shock pressures up to 7.3 GPa and shock energies up to 671 J/g. Shock pressures were calculated using hugoniot parameters for porous elemental powd...

Readily available inexpensive substrate with high product yield is the key to restoring acetone-butanol-ethanol (ABE) fermentation to economic competitiveness. Lactose-replete cheese whey tends to favor the production of butanol over acetone. In the current study, we investigated the fermentability of milk dust powder with high lactose content, for ABE production by Clostridium acetobutylicum a...

Even if drugs are accurately dispensed, it is difficult to ensure their safety in the absence of an error-free medication system when or after drugs are given to patients. In particular, most powders are white and are impossible to distinguish based on appearance after they are placed in powder packages. In this study, we newly developed a system in which prescription order information is bar-c...

We report the characterisation of printed circuit boards (PCB) metal powder filters and their influence on the effective electron temperature which is as low as 22 mK for a quantum dot in a silicon MOSFET structure in a dilution refrigerator. We investigate the attenuation behaviour (10 MHz-20 GHz) of filter made of four metal powders with a grain size below 50 μm. The room-temperature attenuat...

Detergent powders are sometimes processed into compact tablets for cleaning purposes based on the advantage of dosage, minimised dusting and packaging its offers over their powder counterpart. The flow-ability greatly influences handling. The particle size within the powder plays a key role on handling, flow-ability and the strength of the produced compact detergent tablet. The Ariel powder use...

Fruit peels of Banana, Pomegranate, Sweet lime and Orange are highly rich in potash, ion, Zinc etc. Above fruit peels powder were formulated from the trace amounts and gradually increased for the preparation of three formulations as Formulation 1, Formulation 2 and Formulation 3. Three different formulations were applied for plant growth in two methods such as fruit peel powder, fruit peel powd...

BACKGROUND Chronic constipation is an important clinical condition which can result in serious discomfort and even require hospitalization. Powder and liquid lactulose are designated as clinically equivalent for the treatment of constipation, but there are significant differences in the taste, consistency, and portability of the products, which may affect patient compliance and therefore clinic...

The aim of the study was to determine the effects of levofloxacin on the phagocytic and intracellular killing functions of human neutrophils at different therapeutic concentrations and to investigate the possible differences between pure powder and pharmaceutical form of levofloxacin on the neutrophil functions. Neutrophils obtained from healthy volunteers were incubated with both pure powder a...
