The porcine circovirus type 2 (PCV2) antibody and DNA status of porcine plasma products collected during the commercial spray-drying process were evaluated. Samples evaluated included 52 pooled liquid plasma (fresh) samples collected at 14 regional abattoirs before transport to 1 of 2 spray-drying facilities, 32 pooled liquid plasma (concentrated) samples collected after arrival at the spray-dr...

We find that Mycobacterium smegmatis survives spray drying and retains cell viability in accelerated temperature stress (40 °C) conditions with a success rate that increases with increasing thermal, osmotic, and nutrient-restriction stresses applied to the mycobacterium prior to spray drying. M. smegmatis that are spray dried during log growth phase, where they suffer little or no nutrient-redu...

Two studies were conducted to evaluate the effects of spray-dried blood meal and its pH on nursery pig performance. Spray-dried blood meal pH decreases as storage time increases prior to spray drying. In Exp. 1, addition of 2.5% spray-dried blood meal to the diet improved ADG and ADFI in nursery pigs (15.4 lb to 35.9 lb), but did not influence feed efficiency. In Exp. 2, the inclusion of 5% spr...

Spray combustion is encountered in many engineering applications, such as internal combustion engines and gas-turbine aircraft engines. In these systems, the concurrent processes of liquid atomization, droplet evaporation, turbulent dispersion, and combustion interact and strongly affect each other, which makes experimental measurement and high-fidelity simulation challenging. To understand the...

To facilitate the better use of RP-3 kerosene in compression ignition engines, auto-ignition behaviors spray were experimentally investigated an optical rapid machine. Results show that most tests have good ignitability and combustion performance. For all successful ignited cases, flame kernel was found to be formed before steep rise pressure, which explained image-based delay time is always sh...

In this paper, view of the traditional temperature control and spray gun pressure in coating drum current medicine machine, control: adopting intelligent domain's mold PID method, model simulation is used to verify accuracy taking powder outlet as input closed-loop feedback, can be kept constant demand pot well ensured.

The purpose of this study was to evaluate the pharmacokinetic behavior of florfenicol spray-dried nanosuspersion after oral administration to rabbits and to compare its oral bioavailability characteristics to that of a known soluble powder. Florfenicol spray-dried nanosuspersion was produced by high pressure homogenization followed by spray drying. Plasma concentrations were determined by HPLC....

Whether spray or immersion fixation results in higher adequacy rates for thyroid fine-needle aspiration is not known. I compared 1-year adequacy rates, number of cells, and atypia rates for immersion fixation with split spray fixation and immersion. Adequacy rates increased from 71.9% (289/402) for complete immersion to 78.1% (332/425) with spray fixation of half of the slides (P = .02). The sp...

Spray drying is a commonly used method of drying a liquid feed through a hot gas. This study aims to obtain the empirical model of the spray drying process of full cream milk using a nozzle atomizer spray dryer, Lab-Plant SD 05 Laboratory Scale Spray Dryer. Inlet air temperature was chosen as the manipulated variable and outlet air temperature was the controlled variable. No disturbance was con...

Pesticides are widely used in agriculture for the management of pests (weeds, insects or pathogens). They are generally applied as a spray to cover the target (e.g. an insect, leaf surfaces or part of a plant) with pesticide-laden droplets. Spray may, however, be lost to nontarget areas within a crop through deposition on to the soil or on non-target plant surfaces. The plant architecture of th...
