The Galton board is an upright board with evenly spaced nails driven into its upper half. The nails are arranged in staggered order. The lower half of the board is divided with vertical slats into a number of narrow rectangular slots. From the front, the whole installation is covered with a glass cover. In the middle of the upper edge, there is a funnel in which balls can be poured, the diamete...

T he role of medical devices, such as bronchoscopes, in the transmission of healthcare-associated infections (HAIs) has long been recognized, however, the evidence that environmental and medical equipment surfaces play a role in the transmission of HAIs has been weak. Studies have demonstrated that pathogens can be transmitted from surfaces to personnel and patients, and that these pathogens ar...

A study has been done to analyse the microbiological quality of salads served along with street foods of Hyderabad. A total of 163 salad samples, 53 of carrot and 110 of onion samples, were collected from four different zones of Hyderabad. About 74% and 56% had Staphylococcus aureus in carrots and onions, respectively. Fifty-eight percent of carrots and forty-five percent of onions samples cont...

Modified handling is often claimed to reduce (sub-)lethal impacts among organisms caught-and-released in fisheries. Improving welfare of discarded fish warrants investigation, when their survival is of both economic and ecological importance. In this study, juvenile yellowfin bream (Acanthopagrus australis) were trawled in an Australian penaeid fishery and then discarded after on-board sorting ...

BACKGROUND Most of the scientific publications from the maritime area are studies about the mortality and morbidity, while studies about the present hazards of potentially dangerous exposures are relatively rare. AIMS To describe the seafarers' assessments of the occupational safety on board, their exposure to chemicals and the use of personal protection equipment and to identify the areas fo...

An oxygen gas microsensor based on nanostructured sol-gel TiO2 thin films with a buried Pd layer was developed on a silicon substrate. The nanostructured titania thin films for O2 sensors were prepared by the sol-gel process and became anatase after heat treatment. A sandwich TiO2 square board with an area of 350 μm × 350 μm was defined by both wet etching and dry etching processes and the wet ...

We present a spectral analysis of a sample of red-sequence galaxies identified by van Dokkum (2005) as dry merger remnants and ongoing dry mergers. Kinematics, stellar population absorption features, and ionisation from emission lines, are derived. We find that approximately half of the sample showing strong tidal features have younger stellar populations than a control sample at a given veloci...
