The aim of this study was to evaluate the marginal adaptation of Turkom-Cera all-ceramic crowns compared to In-Ceram and Procera AllCeram systems. The influence of finish line design (chamfer or shoulder) on the marginal adaptation of Turkom-Cera all-ceramic crowns was also investigated. Thirty human premolars were prepared with chamfer margins and assigned to either the Turkom-Cera, In-Ceram, ...

BACKGROUND The intracellular bacterium Lawsonia intracellularis is an important pathogen in modern swine production. The aim of this study was to investigate the effect of a live attenuated L. intracellularis vaccine (Enterisol Ileitis®) on the health and production parameters of weaned and finishing pigs in a commercial Finnish 850-sow farm with diagnosed L. intracellularis infection. The herd...

In order to minimize odor and manage nutrients in liquid pig manure we need to be able to predict what operational practices most influence the concentrations of volatile fatty acids (VFAs), ammonium nitrogen (NH(4)(+)-N), and other nutrients present in the manure. To determine this, we collected manure from 15 pig operations in southwestern Ontario in the fall of 2001 and 2002 and spring of 20...

conclusions bilateral anterior shoulder dislocation is rare. it could be undiagnosed, especially when there is no clear history of major trauma. by awareness of such unusual possibility, early diagnosis, treatment, and reduction can provide desirable outcome. introduction shoulder dislocation is the most common presentation of joint dislocation in emergency department (ed). bilateral shoulder d...

osteoid osteoma is a benign bone tumor and accounts for 10% of benign tumors. almost any bones can be involved but half of cases involving femur or tibia. osteoid osteoma is a rare tumor of the scapula with only 18 reported cases in the literature. we presented a case of osteoid osteoma of the scapula in right shoulder in angle of coracoid and geloneid in a 34- year old woman. she had right rad...

OBJECTIVE To evaluate effect of various regimens for administration of antimicrobials in feed on growth rate and feed efficiency (feed/gain) of pigs in multisite production systems. DESIGN Controlled trial. ANIMALS 24,099 growing pigs in 3 multisite production systems. PROCEDURE 10 trials involving various regimens for administration of antimicrobials in feed were evaluated. Trial 1 compa...

BACKGROUND Repair is a conservative treatment of defective composite restoration. Sealing the repair interface is a critical factor to achieve successful repaired restorations. OBJECTIVE The aim of this study was to evaluatethe effect of three finishing times on the microleakage at the composite-repair interface. METHOD Eighty composite specimens (Z250) were made and aged for eight weeks in...

Questions have been raised regarding which of the three legs of a triathlon influences the final finishing position. Some coaches subjectively believe that the swim and run are more important than the cycle, especially since the introduction of drafting during the cycle. This study analysed race position shifts between each of the three disciplines to assess the importance of the swim finish po...

One of the newly developed methods for obtaining super finished surfaces for freeform is Magnetorheological finishing (MRF). MRF is an advanced finishing process in which the grinding force is controlled by magnetic field. The material removal in MRF is governed by the magnetorheological fluid which mainly consists of carbonyl iron (CI), abrasives particles, carrier fluids and additives. MRF pr...

Men outperform women in many athletic endeavors due to physiological and anatomical differences (e.g. larger and faster muscle); however, the observed sex differences in elite athletic performance are typically larger than expected, and may reflect sex-related differences in opportunity or incentives. As collegiate rowing in the United States has been largely incentivized for women over the las...
