Introduction Nowadays, single-use bioreactors are widely accepted in pharmaceutical industry. This is based on shorter batch to batch times, reduced cleaning effort and a significantly lower risk of cross contaminations [1,2]. One large field of the application of single-use bioreactors is the seed train cultivation of mammalian cells [1]. The focus is further extended to perform state of the a...

objective: the aim of this study was to evaluate and compare the cleaning ability and instrumentation time of manual and rotary methods used for preparation of primary anterior teeth. materials and methods: forty-four primary anterior teeth were used in this experimental study. access cavities were prepared and india ink was injected into the canals. the samples were divided into three groups a...

A flax fiber pilot plant is needed to process small samples of flax straw into fibers to facilitate research on retting and fiber properties. Our objective was to develop and test a modular design for a flax processing pilot plant based on a commercial line that was capable of cleaning fiber and seed flax straw from unretted, dew-retted, and enzyme-retted samples. The USDA Flax Fiber Pilot Plan...

In accordance with a plan to investigate as fully as possible the essential chemistry of the strophanthins and other cardiac glucosides, we have attempted to include for comparative purposes, as opportunity presented itself, a study of the digitaloid glucosides and aglucones which occur in the different species of Strophanthus plants. Our own and previous investigations have had to do principal...

This study aims to develop and evaluate of machine peeling cleaning peanut seed be using in small medium production units. All experiments were carried out at average moisture contents 7.53% (d.b.) for seed. Experiments conducted drum speeds 100, 200, 300 400 rpm, number rows 4, 8 12 air velocity 1, 2, 3 4 m/s. Results showed that the highest productivity was 80 kg/h with speed from rpm while v...

Human activities, from resource extraction to recreation, are increasing global connectivity, especially to less-disturbed and previously inaccessible places. Such activities necessitate road networks and vehicles. Vehicles can transport reproductive plant propagules long distances, thereby increasing the risk of invasive plant species transport and dispersal. Subsequent invasions by less desir...

There is concern that gins located in boll weevil, Anthonomus grandis grandis Boheman, eradication zones may become points of reintroduction when they process cotton grown in a neighboring infested area. We estimated boll weevil survival through two typical machine sequences used in commercial cotton gins to clean and dry the seed cotton in advance of the gin stand, as well as separately throug...
