Introduction Load-carrying capacity of gears, especially the surface durability, is influenced by their tooth surface roughness in addition to their tooth profiles and tooth traces (Refs. 1 and 2). The harder the gears are, the smoother their tooth surfaces and the more accurately their tooth profiles should be finished in order to obtain high load-carrying capacity. Through research, the relat...

A genetically modified corn hybrid homozygous for the lpa1 allele, containing low phytate (LP), and its nearly isogenic equivalent hybrid (normal) were compared in two experiments with growing-finishing swine. In Exp. 1, 210 barrows (27 kg) were allotted to one of six dietary treatments with two corn hybrids (LP and normal) and three P feeding regimens. There were five replicate pens (seven pig...

AIMS The aims of this study were to evaluate the effect of various finishing and polishing procedures on the surface roughness of six different composite resin materials (Artemis Enamel, TPH Spectrum, Filtek A-110, Filtek Supreme Enamel, Solitaire 2, and Filtek P-60) as well as to evaluate the effectiveness of the surface sealant application (BisCover) on the surface roughness after finishing a...

Virtually all products that are finished require some pre-finishing procedure such as cleaning, stripping, or pickling. Without a properly cleaned surface, even the most expensive coating will fail to adhere or protect the workpiece. Depending on the process being performed, the degree of cleanliness will vary. Finishing operations such as phosphating, chromating, or electropolishing do not req...

Two studies were conducted to determine the effects of eliminating the supplemental vitamin and minerals during the last 30 d of finishing on pig performance. The first study was conducted in a controlled university environment and the second under field conditions. Deletion of vitamin and mineral supplements for the last 30 d of finishing had no effects on pig performance or general health of ...

background: in recent years, dietary fat supplementation has become a common practice and fat supplemented diets have had variable effects on animal performance and carcass characteristics. objectives: this study was conducted to determine the effect of  increasing the levels of sesame oil on performance, rumen parameters and plasma lipid profile in finishing chal lambs. methods: eighteen male ...

The results of studies aimed at the creation new functional textile materials through use microencapsulated TE (textile excipients) and metal nanoparticles, non-metal oxides, as well clays natural origin were summarized. developed methods for synthesis capsule shells various architectures, including synthetic polyelectrolytes, presented. technologies encapsulation preparations aromatic, repelle...

PURPOSE (1) to examine the relation between pulmonary diffusing capacity and marathon finishing time, and (2), to evaluate the accuracy of pulmonary diffusing capacity for nitric oxide (DLNO) in predicting marathon finishing time relative to that of pulmonary diffusing capacity for carbon monoxide (DLCO). METHODS 28 runners [18 males, age = 37 (SD 9) years, body mass = 70 (13) kg, height = 17...

This study investigates a Deburring process which is integrated with a robotics application. Conventional tumble deburring processes have been used for years in the surface finishing industries. The manual process is tedious, inconsistent and inaccurate. Automation in the finishing process has been proved very beneficial. Integration of robots in the process provides more flexible and convenien...

Five composite filling materials were finished using six finishing procedures currently in clinical use. The average roughness produced by each procedure was measured by means of a Surfanalyzer with four replications for each procedure on each of the five materials. Statistical analysis indicated that finishing with silicon carbide disks produced the smoothest surfaces. Acceptable surfaces were...
