We have not found in the computer graphics literature what we believe may be the simplest algorithm for implementing a 3D rotation with a mouse. We present this algorithm, and observe that it leads to new mathematical realizations of the 3D rotation group and its double-cover, the unit quaternions. We use this to obtain an algorithm for interpolating rotations of a 3D scene that is more efficie...
BACKGROUND/OBJECTIVES Inflammation is associated with various types of acute and chronic alcohol liver diseases. In this study, we examined whether umbelliferone (7-hydroxycoumarin, UF) ameliorates chronic alcohol-induced liver damage by modulating inflammatory response and the antioxidant system. METHODS Rats were fed a Liber-Decarli liquid diet containing 5% alcohol with or without UF (0.05...
Double-walled polyurethane/poly(urea-formaldehyde) microcapsules (PU/UF) are prepared for use in self-healing materials. This modified encapsulation procedure combines two chemistries to form more robust capsule shell walls in a single operation. Robust capsules are formed by this procedure as long as the aromatic polyisocyanate prepolymer is soluble in the core liquid and the core liquid is co...
The content and distribution of stilbenes and resin acids in Scots pine (Pinus sylvestris) and spruce (Picea abies), sampled in central Norway, have been examined. The contents of pinosylvin stilbenes in pine heartwood/living knots were 0.2-2/2-8 %(w/w). No stilbenes could be detected in spruce (Picea abies). The resin acid contents of pine sapwood/heartwood and knots were 1-4 and 5-10 % (w/w),...
In recent years, the production and consumption of thermally modified wood (TMW) has been increasing. Offcuts other waste generated during TMWs processing into products, as well already disposed products based on can be an input recycled raw material for particleboards (PBs). a laboratory, 16 mm thick 3-layer PBs bonded with urea-formaldehyde (UF) resin were produced at 5.8 MPa, 240 °C 8 s pres...
The high demand for wood-based composites generates a greater use of wood adhesives. current industrial challenge is to develop modified synthetic adhesives remove harmful formaldehyde, and test natural scope the research included manufacturing high-density fiberboards (HDF) using binders such as polylactic acid (PLA), polycaprolactone (PCL), thermoplastic starch (TPS) with different resination...
The preparative purification of liriodendrin from Sargentodoxa cuneata using macroporous resin combined with crystallization process was evaluated. The properties of adsorption/desorption of liriodendrin on eight macroporous resins were investigated systematically. X-5 resin was selected as the most suitable medium for liriodendrin purification. The adsorption of liriodendrin on X-5 resin fitte...
BACKGROUND Uterine fibroids (UF) affect 77% of women by menopause, and account for $9.4 billion in annual healthcare costs. Type-2-diabetes (T2D) has inconsistently associated with protection from UFs in prior studies. To further evaluate the relationship between T2D and UFs we tested for association between T2D and UF risk in a large clinical population as well as the potential differences due...
background and objective: during cheese ripening, some of water insoluble casein change to water soluble nitrogen which are include intermediate hydrohysate protein and free amino acids. materials and methods: these enzymes save their activities in pasteurization temperature and also uht processing. in this study effect of number of pscyrotroph bacteria on physical and chemical properties on uf...
Intradialytic hypotension (IDH) is one of the most common complications of hemodialysis (HD) treatment. The initiating factor of IDH is a decrease in blood volume, which is related to an imbalance between ultrafiltration (UF) and refilling rate. Impaired reactivity of resistance and capacitance vessels in reaction to hypovolemia plays possibly a major role in the occurrence of IDH. These vessel...
