Experiments were conducted to study the effectiveness of powders of some underutilized botanicals for the control of Sitophilus zeamais. The tested plants are: Piptadeniastrum africanum, Piper guineense, Alstonia boonei, Garcinia kola, Xylopia aethiopica, Picralima nitida and Aristolochia repens. The effects of the powders were observed at different dosage rates : 0.0g (Control), 0.5g, 1.0g, 1....

Although many consumers know that pulses are nutritious, long preparation times are frequently a barrier to consumption of lentils, dried peas and chickpeas. Therefore, a product has been developed which can be used as an ingredient in a wide variety of dishes without presoaking or precooking. Dried green peas, chickpeas or lentils were soaked, cooked, homogenized and spray-dried. Proximate ana...

Yttrium iron garnet powders have been synthesized by chemical coprecipitation using two different precursors, nitrates and chlorides, and by an oxides mixture route. It is shown that depending on the precursors and synthesis conditions used pure yttrium iron garnet powders can be obtained with a mono or multidomain magnetic behaviour. The yttrium iron garnet crystalline structure, as studied by...

The aim of this work was to investigate the suitable rice varieties for developing pharmaceutical buccal films. Two rice varieties with extreme difference in amylose content were used. Rice powders were chemically modified to yield the carboxymethyl rice prior to film preparation. Scanning electron microscope (SEM) and X-ray diffractometer (XRD) were used to investigate the solid structure of r...

There is little published data on the performance of hand-portable polymerase chain reaction (PCR) systems that can be used by first responders to determine if a suspicious powder contains a potential biothreat agent. We evaluated 5 commercially available hand-portable PCR instruments for detection of Bacillus anthracis. We used a cost-effective, statistically based test plan to evaluate system...

Until now, the adverse effects of toner powders on humans have been considered to be minimal. However, several recent reports have suggested possible significant adverse health effects from toner dust inhalation. The aim of this study was to evaluate the genotoxic potential of black toner powders in vitro. For the study of DNA damage, A549 cells were exposed to toner-powder suspensions and to t...

the dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. cu and ni unites nanocatalyst powders sithcomposition of caned], and nife204 were synthesized by a sol-gel auto catalnic combustion process. themolar ratio between metal ions and urea was 11.2. the sob gel process was done at 8...

The research study was conducted to develop a healthy vegetables soup powder supplemented with soy flour, mushroom, moringa leaf and compare its nutritional facts with locally available soup powders. Proximate analysis and sensory evaluation were done by standard method. In this study, moisture, ash, protein, fat, fiber, carbohydrate, and energy content were ranged from 2.83% to 5.46%, 9.39% to...

Dry powders containing a live-attenuated Newcastle disease vaccine (LZ58 strain) and intended for mass vaccination of poultry were prepared by spray drying using mannitol in combination with trehalose or inositol, polyvinylpyrrolidone (PVP) and/or bovine serum albumin (BSA) as stabilizers. These powders were evaluated for vaccine stabilizing capacity during production and storage (at 6 °C and 2...

Archiving functionally gradient materials (FGM) fabrication via digital manufacturing methods has attracted considerable attention in recent years. In this paper, a new FGM powder feeder and its flexible numerical motors control solution used in electromagnetism compressed plasma deposition manufacturing process was developed. The motors control hardware circuit and its Superior computer contro...
