In this study, different methods, including acid hydrolysis (phosphoric and formic acid), thermohydrolysis, microwave methods were tested for recycling of fiberboards made 100 % beech 70 + 30 pine wood fibers, which are widely sold in the market. The impacts using on fibers investigated with help a device that determines fiber dimensions according to optical principles. laboratory setting, test...

In-plane density variations exist in oriented strandboards (OSB) due to random flake deposition in mat forming. The integrity of structural performance of the board in service depends on the degree of homogeneity of its horizontal density. In this paper, non-contact ultrasound (NCU – air-coupled) in through transmission was used specifically to correlate the NCU parameters to the spatial densit...

Adolescent alcohol use behaviors are influenced by familial patterns and neighborhood factors. This work explored the influence of individual, family, and environment on alcohol use. Baseline data from a randomized controlled trial with Black mothers son dyads (n=382) were paired with census tract and alcohol control board data. Among mothers, younger age, along with neighborhood factors of alc...

[1] The paper deals with initial analyzes of radio occultation measurements of the ionosphere carried out on board the CHAMP satellite since 11 April 2001. The accuracy of the operationally retrieved electron density profiles has been estimated by comparing with independent measurements. The derived ionospheric key parameters such as f0F2 and hmF2 agree with a standard deviation of 18 and 13%, ...

Fuel-cell dynamics have been investigated with a variable-resistance board applied to a high temperature polymer fuel cell, and a particular pattern has been identified in the voltage-current density diagram. A model has been developed, using a characteristic equation to represent the external circuit as a generally nonlinear resistive load, possibly nonlinear and time-varying, rather than assu...

In this paper we present a new approach to classifying radiographs, which is the first important task of the IRMA system. Given an image, we compute posterior probabilities for each image class, as this information is needed for further IRMA processing. Classification is done by using an extended version of Simard’s tangent distance within a kernel density based classifier. We propose a new dis...

Transition metal (TM) atoms bound to fullerenes are proposed as adsorbents for high density, room temperature, ambient pressure storage of hydrogen. C60 or C48B12 disperses TMs by charge transfer interactions to produce stable organometallic buckyballs (OBBs). A particular scandium OBB can bind as many as 11 hydrogen atoms per TM, ten of which are in the form of dihydrogen that can be adsorbed ...

The gas phase spectrum of the cyclic C18 molecule recorded in the laboratory at a temperature typical of diffuse interstellar clouds is compared with absorption features toward Oph and HD 204827 in the 5730–5934 8 region. For the origin band at 5928.5 8 an upper limit to the column density of 1:8 ; 10 cm 2 is inferred. The origin band pattern in the laboratory spectrum changes on lowering the i...
