Study organisms in chronic toxicological bioassays are often provided with excessive resources to remove food limitations as a confounding experimental variable. Under more ecologically realistic situations, resources are often less abundant and such restrictions may alter the responses of organisms to environmental contaminants. Here, we investigated the interaction between resource level and ...

Many marine invertebrates with complex life cycles produce planktonic larvae that experience environmental conditions different from those encountered by adults. Factors such as temperature and food, known to impact the larval period, can also affect larval size and consequently the size of newly settled juveniles. After documenting natural variation in the size of cyprids (the final larval sta...

AIM The purpose of this study was to assess the knowledge and practices of Saudi dentists in finishing and polishing composite restorations. MATERIALS AND METHODS A cross-sectional questionnaire-based study was conducted among 306 Saudi dentists from March to April 2012. The collected data were analyzed using Microsoft Excel 2010 program and descriptive statistics were obtained. RESULTS Com...

Magnetic abrasive machining is a surface finishing technique in which a magnetic field is used to force abrasive particles against the target surface. As such, finishing of conventionally inaccessible surfaces (e.g., the inside surface of a long curved pipe) is possible. The aim of this paper is to study maximum efficiency in terms of material removal rate with respect to magnetic flux density ...

Aim: The objective of the present study is to know the effect of feeding processed sweet sorghum (Sorghum bicolour (L) moench) crushed residue (SSCR) based complete ration on growth, feeding behavior and cost of gain in Murrah buffalo calves in order to compare the feeding value of SSCR with sorghum straw (SS) and also find out the efficient way of utilization of SSCR in the diets of growing bu...

Introduction Four generic types of construction robots have been suggested in [4]. They were an assembling robot, an interior finishing robot, an exterior wall finishing robot, and a horizontal floor finishing robot. The interior finishing robot, as explained there, was designated to execute various interior finishing operations, such as partition erection, painting, plastering, jointing, tapin...

In a series of three experiments, we tested the effects of short-term food variability on the larval development of Petrolisthes cabrilloi. We first reared seven sibling clutches of zoeae at 19°C in ten constant food rations (ranging 2-40 Artemia nauplii d) to determine maximal and minimal values for age and size at metamorphosis to the megalops stage. Mean age at metamorphosis ranged between 1...

vitro digestibility tended to be greater with ammoniation. In the second trial, very high levels of ammonia, urea or glucose were added. Levels of insoluble protein were much higher in this trial than the other. This reflects the high variability of corn silage. Recovery of nitrogen added as ammonia averaged 82 percent while all of the nitrogen added as urea was recovered. The amounts of insolu...

OBJECTIVE This study compared occlusal contact areas of ideally planned set-up and accomplished final models against the initial in class I and II molar relationships at finishing. METHODS Evaluations were performed for 41 post-orthodontic treatment cases, of which 22 were clinically diagnosed as class I and the remainder were diagnosed as full cusp class II. Class I cases had four first prem...
