This study is concerned with the partitioning of cellulolytic activity in the polyethylene glycol/dextran two-phase systems. In the system of 10% (w/w) polyethylene glycol 1500/5% (w/w) dextran 500,000/80% (w/w) crude enzyme at the pH 5, 100%, yield of cellulolytic activity from Penicillium sp. in the top phase was achieved in a single extraction step. Addition of KH2PO4 to this system at a con...

Tungsten rods of 1×1×3mm were exposed at the outer divertor plate of ASDEX Upgrade using a manipulator system. Controlled melting of the W rod in H-mode discharges was induced by moving the outer strike point towards the W-rod position. Visible light emission of ejected W droplets was recorded by fast camera systems. The resulting increase of tungsten concentration in the confined plasma was co...

[1] We developed a 3D Monte Carlo photon tracing program for the transfer of radiation in inhomogeneous and irregular terrain to calculate broadband solar and thermal infrared fluxes. We selected an area of 100 100 km in the Tibetan Plateau centered at Lhasa city and used the albedo and surface temperature from MODIS/Terra for this study. We showed that anomalies of surface solar fluxes with re...

Various NO‐reduction reactions on Pt(100) exhibit similar dynamical behavior, presumably due to an empty site requirement for NO dissociation. This motivates analysis of a lattice‐gas model which incorporates this feature, and which here is chosen to mimic the NO+CO reaction on Pt(100): both reactants adsorb at single empty sites, NO instantaneously dissociates given an adjacent empty site (and...

Two different calcium-binding proteins, S-100 and calmodulin, have been isolated from bovine brain by calcium-dependent affinity chromatography on calmodulin antagonist coupled to Sepharose. Calmodulin antagonist N-(6-aminohexyl)-5-chloro-l-napthdenesulfonamide (W-7) has been coupled to epoxy-activated Sepharose 6B or cyanogen bromide-acitivated Sepharose 4B. S-100-like protein bound to W-7 cou...

This study aimed to produce new edible coatings based on the mixture of sago starch, cellulose nanofiber (CNF), glycerol, and tween-80.The effect starch (5–10 g starch/100 ml distilled water), CNF (0.5–20% w/w), glycerol (10–30% tween-80 (0.5–10% w/w) concentration contact angle (CA), water vapor permeability (WVP), oxygen (PO2) tensile strength (TS) properties were optimized using factorial ex...

Background: Penicillium marneffei infection is the emerging fungal infection in the present day global scenario of HIV pandemic. P. marneffei is a dimorphic fungi with mycelial growth at 37C. Suspicion of P.marneffei infection arises when a immunocompromised individuals especially HIV positive persons present with Molluscum contagiosum like skin lesions. But pulmonary manifestations are not cha...

The effects of phosphorus and nitrogen limitation on polyhydroxyalkanoate (PHA) production and accumulation by activated sludge biomass with acetate as a carbon source were investigated. Pre-selected influent carbon-phosphorus (C:P, W/W) of 100, 160, 250, 500 and 750, and carbon-nitrogen (C:N, W/W) of 20, 60, 100, 125 and 180 were applied in the phosphorus limitation experiments and the nitroge...

Precise determinations of the masses of the W boson and of the top quark could stringently test the radiative structure of the Standard Model (SM) or provide evidence for new physics. We analyze the excellent prospects at a muon collider for measuring MW and mt in the W W and t t threshold regions. With an integrated luminosity of 10 (100) fb , the W -boson mass could be measured to a precision...

OBJECTIVE The aim of this study was to evaluate the microhardness of radicular dentin after treatment with 980-nm diode laser and different irrigant solutions. BACKGROUND DATA There are few reports of the consequences of diode laser irradiation emitted at 980 nm on the mechanical properties of dentin. METHODS Seventy-two single canal, human canines with complete root formation were randomly...
