BACKGROUND There is no conclusive evidence that stimulants have beneficial effects on major associated outcome parameters, particularly school performance. We assessed the differences in school performance among children using methylphenidate at the end of primary school in relation to various parameters of methylphenidate use. METHODS We linked children from a pharmacy prescription database ...

PURPOSE To quantify the accumulative training and match load during an annual season in English Premier League soccer players classified as starters (n = 8, started ≥60% of games), fringe players (n = 7, started 30-60% of games) and nonstarters (n = 4, started <30% of games). Methods Players were monitored during all training sessions and games completed in the 2013-14 season with load quantifi...

The production of Greek-style natural black table olives remains an empirical process relying on spontaneous fermentation despite its economic significance. For this reason producers often resort to increased NaCl concentration of the brine to secure quality of the product. In this study we employ two lactic acid bacteria Leuconostoc mesenteroides subsp. mesenteroides Lm139 and Lactobacillus pe...

This study explored the contribution of finger counting habits to the association of numbers with space (the SNARC effect). First, a questionnaire study indicated that two-thirds of 445 adults started counting on their left hand, regardless of their handedness. Secondly, a group of 53 "left-starters" but not a group of 47 "right-starters" showed a SNARC effect in a parity task. A significant di...

Background Vertical integration of the broiler industry allows producers to combine different biosecurity and sanitation practices, housing technologies, and feeding regimens to improve food safety. The purpose of this study was to investigate the prevalence and distribution of Salmonella, to determine the source of Salmonella contaminants, and to reveal the relationships between isolates at ea...

A cover starter is a single vector that yields a covering array under the actions of groups on both the columns and the symbols of the starter. The existence of this compact representation of covering arrays facilitates effective exhaustive and heuristic search. When the group action on symbols fixes a small number f of symbols, such cover starters lead to covering arrays that embed covering ar...

We use firm level data to assess the role of exporting in the link between financial health and firm survival. The data are for the UK and France. We examine whether firms at different stages of export activity (starters, exiters, continuers, switchers) react differently to changes in financial variables. In general, export starters and exiters experience much stronger adverse effects of financ...

the aim of this study was to investigate the effects of starters and storage temperature (4 ºc, 25 ºc) onmicrobiological and physicochemical properties, volatile compounds and sensory evaluation of kefir.kefirs produced by kfa and chr. hansen starters were stored at 4 ºc and 25 ºc for 40 days. ph andacidity at 4 ºc did not change (p ≥ 0.05), while at 25 ºc ph and total solid decreased as well a...

The purpose of this study was to investigate the distribution of Salmonella species in an integrated broiler supply chain in Korea. A total of 1,214 samples from various steps of an integrated broiler production company including broiler breeder farms, broiler farms, broiler trucks, slaughterhouse, and retail chicken meats were collected and investigated. Salmonella was detected in 195 of the s...
