To achieve the benefits that composite restorations can provide, it is incumbent on dentists to understand the importance of proper finishing and polishing techniques and how to incorporate them appropriately into everyday practice. A smooth surface finish is clinically necessary because the presence of surface irregularities from poor finishing and polishing can lead to staining, plaque retent...

Because grains comprise the major portion of diets for finishing beef cattle, and grains contain little calcium, limestone is typically added to finishing diets at levels of .7 to more than 1% of the dry matter. Feedgrade limestone varies in quality and consistency, which could alter performance responses by finishing beef steers. Selection of superior sources of limestone and(or) treatment of ...

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 ...

abstract  background: rotator cuff tear is one of the most common causes of shoulder  complaints in the elderly. based on the severity and patient's condition, a variety of  methods applies to manage the tear and surgery is an important method, which could  be done by open or arthroscopic technique. the current study aimed to investigate  and report short-term results of arthroscopic repair of ...

background: office workers spend a long period of time behind a computer during working hours. the relation between the posture of sitting during work with computer and neck pain is still debatable. even though some researchers claim a significant difference in head posture between patients with neck pain and pain-free participants, the fhp (forward head posture) has not always been associated ...
