There have been reports in the literature of acute and chronic silicosis and connective tissue disease induced by occupational exposure to silica in factories producing scouring powder. Reports of connective tissue diseases induced by intentional inhalation of such a powder are rare and perhaps underestimated. We report the case of a young woman who developed Sharp's syndrome 5 yrs after diagno...

to study the effect of herb ginger powder on performance, carcass characteristics and blood parameters of broilers used from 192 broiler chicks (ross ) in a completely randomized design with 4 treatments and 4 replicates ( each replicate of 12 chicks ). all treatments, including different levels of ginger powder ratios of 0, 0.5, 1, 1.5 percent respectively called t1, 2t, t3 and t4 that were ad...

INTRODUCTION The purpose of this in vitro study was to compare the antibacterial activity of Calcium Enriched Mixture (CEM) with ProRoot Mineral Trioxide Aggregate (MTA) against Enterococcus faecalis (E. faecalis) in the presence/absence of dentin powder. MATERIALS AND METHODS Two series of freshly mixed (10, 50, and 100 mg), set crushed powder (10, 50, and 100 mg), and pieces of uncrushed se...

A part of a complete expert system for powder technology is presented. This part of the system deals with the powder selection according to predetermined recommended or required material properties, and specific powder characteristics. Then, determining the most common powder production (i.e. processing) method, which satisfies the specified powder requirements for a specific application. For t...

Powder bed binder jet printing (BJP) is an additive manufacturing method in which powder is deposited layer-by-layer and selectively joined in each layer with binder. The data presented here relates to the characterization of the as-received feedstock powder, BJP processing parameters, sample preparation and sintering profile ("Effect of solutionizing and aging on the microstructure and mechani...

Abstract—Powder metallurgy (P/M) is the only economic way to produce porous parts/products. P/M can produce near net shape parts hence reduces wastage of raw material and energy, avoids various machining operations. The most vital use of P/M is in production of metallic filters and self lubricating bush bearings and siding surfaces. The porosity of the part can be controlled by varying compacti...

A predictive model for powder compaction has been developed that incorporates unprecedented flexibility to design powder press tooling and reliable powder pressing processes. Sandia’s finite element (FE) toolkit comprises the heart of the modeling software, and a unique concept was developed to design a variable dimension and parameter template to easily build/design dies/components on a comput...

The mechanical properties of luting agents are determined by the mixing ratio of powder and liquid. The purpose of this in vitro study was to evaluate the therapeutic range of zinc carboxylate cements by investigating the mechanical properties of such cements when formulated using erroneous powder/liquid ratios. Using the recommended powder/liquid ratio as a standard, four different mixing rati...

Cocoa powder is rich in flavonoids, which have many beneficial effects on human health, including antioxidative and anti-inflammatory effects. The aim of our study was to investigate whether the intake of cocoa powder has any influence on hyperlipidemia and atherosclerosis and examine the underlying molecular mechanisms. We fed apoE knockout mice a Western diet supplemented with either 0.2% (lo...

This study was conducted to investigate the effects of kimchi powder and onion peel extract on the quality characteristics of emulsion sausage manufactured with irradiated pork. The emulsion sausages were formulated with 2% kimchi powder and/or 0.05% onion peel extract. The changes in pH value of all treatments were similar, depending on storage periods. The addition of kimchi powder increased ...
