Leishmaniases are neglected tropical diseases exhibiting complex transmission cycles due to the number of parasite species circulating, sand fly species acting as vectors and infected mammals, including humans, which are defined in the New World as accidental hosts. However, current transmission scenarios are changing, and the disease is no longer exclusively related to forested areas but urban...

Unlike green sand, chemically bonded sand cannot be used again and again without reclamation because in this system, the mixed sand gets it`s strength through chemical reaction which is irreversible in nature. Each sand particle is coated with this reacted chemical, which behaves like an inert element after usage once. This inert coating also called “Dead” binder needs to be removed from the us...

Fish (herring, cod, eelpout, round goby, flounder, perch, lamprey, pikeperch, sand eel and lesser sand eel) caught in the Gulf of Gdansk in 1992 contained the residues of penta(PCBz) and hexachlorobenzene (HCBz) in concentrations from 0.09 to 0.75 and from 0.36 to 3.7 ng/g wet weight (3.3-14 and 6.5-41 ng/g lipid weight), respectively. Both compounds were identified and quantified using capilla...

Eight waterworks in The Netherlands, which use surface water as their raw water source, were sampled repeatedly between November 1978 and June 1981. At five waterworks , 30 of 45 samples of raw water contained viruses. Of 55 samples of partially purified water, 11 were virus positive, including 8 after coagulation, sedimentation, and rapid sand filtration, 2 after storage, coagulation, sediment...

The thermal biology of the small sand lizard, Liolaemus occipitalis, was studied in the coastal sand dunes at Quintão Beach (Palmares do Sul, Rio Grande do Sul, Brazil; 30 degrees 24' S and 50 degrees 17' W), between September, 1998 and August, 1999. Liolaemus occipitalis presented a mean body temperature of 30.89 degrees C (SD = 4.43 degrees C; min = 16.4 degrees C; max = 40.2 degrees C; N = 2...

We present an interactive sand art drawing system using one RGB-D sensor, such as Kinect. Our system supports the common sand drawing functions, such as sand erosion, sand spilling, and sand leaking. To use hands to draw virtual sand on a drawing plane, we design four key gestures which enable drawing manipulation actions for sand. The basic idea is that the gesture of one hand controls the dra...
