We evaluated 6- and 7-month-olds' preference and memory for expressive recordings of sung lullabies. In Experiment 1, both age groups preferred lower-pitched to higher-pitched renditions of unfamiliar lullabies. In Experiment 2, infants were tested after 2 weeks of daily exposure to a lullaby at one pitch level. Seven-month-olds listened significantly longer to the lullaby at a novel pitch leve...

Despite increased interest in ultra-endurance events, little research has examined ultra-triathlon performance. The aims of this study were: (i) to compare swimming, cycling, running, and overall performances in three ultra-distance triathlons, double Ironman distance triathlon (2IMT) (7.6 km swimming, 360 km cycling, and 84.4 km running), triple Ironman distance triathlon (3IMT) (11.4 km, 540 ...

Ant Colony System (ACS) is the most popular algorithm used to find a shortest path solution in Traveling Salesman Problem (TSP). Several ACS versions have been proposed which aim to achieve an optimum solution by adjusting pheromone levels. Embedding Malaysian House Red Ant behavior into ACS known as Dynamic Ant Colony Systems with Three Level Updates (DACS3) has increased the ability to reach ...

high mortality and labor costs are associated with first-feeding sturgeon culture, particularly during the period of dietary transition from live to formulated feed. therefore we investigated the effects of various feeding treatments on the survival and growth of the persian sturgeon ( acipenser persicus ) larvae during a 20-day culture period. three replicate groups (250 fish/replicate) of fir...

A 60-days feeding trial was conducted to study the effect of higher temperature (32°C) in comparison to ambient temperature (24.5°C) on different metabolic enzyme namely, aspartate aminotransferase (AST), alanine aminotransferase (ALT), adenosine triphosphatase (ATPase), acid phosphatase (ACP) & alkaline phosphatase (ALP) activities in different tissues of Pangasianodon hypophthalmus. AST activ...

regarding to rapidly changing and highly competitive business environment it will become increasingly important for organizations to measure their performances appropriately. with respect to special characteristics of pharmaceutical industry and lack of reported performance measurement, this study tries to design an integrated performance measurement model for pharmaceutical companies. for gene...
