In order to master effectiveness situation of underground coal mine spray and dust reduction, analyze and improve the process of spray and dust reduction which effect is non-ideal, feasibility of introducing process capability analysis as scientific management method was investigated. Measuring tool was analyzed with measurement system analysis which guaranteed accuracy and precision of measure...

Two trials were conducted to determine the effects of irradiation of spray-dried blood meal and animal plasma on nursery pig growth performance. In Exp. 1, irradiation of spray-dried blood meal resulted in improved ADG and F/G and tended to increase ADFI for the 14 d experiment. The majority of the increase in growth performance occurred during the first week of the trial. In Exp. 2, ADG and AD...

introduction use of hadron therapy as an advanced radiotherapy technique is increasing. in this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. in this study, monte carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. materials and methods i...

In manufacturing, thermal spray technology encompasses a group of coating processes that provide functional surfaces to improve the performance of the components and protect them from corrosion, wear, heat and other failings. Many types and forms of feedstock can be thermal sprayed, and each requires different process conditions and life cycle preparations. The required thermal energy is genera...

Spray drift assessment encompasses classification of the capacity of each sprayer/ technology/setting combination to reduce or avoid the spray drift risk, as well as drift measurement to define buffer zones mandated during pesticide application. Compounding the challenge of these tasks is the great variability of field evaluation results from environmental conditions, spray application technolo...

It is not known whether sea spray droplets can act as agents that influence air-sea gas exchange. We begin to address that question here by evaluating the time scales that govern spray-mediated air-sea gas transfer. To move between the interior of a spray droplet and the atmospheric gas reservoir, gas molecules must complete three distinct steps: (1) Gas molecules must mix between the interior ...

A two-part study was conducted at a commercial beef slaughter plant to determine the effects of conventional and spray chilling on carcass yields and traits, and also to determine the effects of carcass spacing on carcass yields in a spray-chilling system. In the first part, 15 steer beef carcasses per day were selected on three consecutive days, and alternate right and left sides were subjecte...

Seaweeds and seaweed extract (SWE) possess antimicrobial, anti-inflammatory, prebiotic, and growth-promoting properties. Extracts can be prepared in different ways including wet, spray-dried, and freeze-dried forms. The aim of this study was to determine if spray drying of laminarin and fucoidan derived from Laminaria digitata had an effect on the microbiological and cytokine profile of the gas...

Considering heavy forged parts presented that water spray is an appropriate technique as quenching operation. In general, the rapid cooling causes residual stress field due to the dis-homogeneity of the distribution of temperature in the part and the different microstructural phases. In comparison with other conventional quenching methods, spray-quenching method could have a capability to contr...

A system is introduced for the simulation of spray painting. Head mounted display goggles are combined with a tracking system to allow users to paint a virtual surface with a spray gun. Ray tracing is used to simulate droplets landing on the surface of the object, allowing arbitrary shapes and spray gun patterns to be used. This system is combined with previous research on spray gun characteris...
