The target of this study was to investigate the possibility of MDF productionfrom Eucalyptus camaldulensis wood. MDF fibers were produced applying threelevels of steaming time. Laboratory MDF boards were produced using thegenerated fibers and different pressing temperature and time. Physical andmechanical properties of MDF panels were measured using relevant EU testmethods and were statisticall...

Statement of the Problem There are some concerns regarding the effect of chlorhexidine (CHX) applied for cavity disinfection on the bond strength of adhesive restorations to dentin. Purpose This study sought to assess the effect of CHX on the shear bond strength (SBS) of Equia resin-modified glass ionomer cement (RMGIC) to dentin in permanent teeth. Materials and Method In this experimental...

A convenient route to organogels templated by high internal phase emulsions has been developed. Key is the use of a waterborne polymer latex loaded with a multiple hydrogen bond (MHB) functionality that becomes disentangled and transfers across the oil-water interface forming a gel network in the oil phase via hydrogen bond interactions.

In this paper, we present an immersed boundary (IB) method to simulate a dry foam, i.e., a foam in which most of the volume is attributed to its gas phase. Dry foam dynamics involves the interaction between a gas and a collection of thin liquidfilm internal boundaries that partition the gas into discrete cells or bubbles. The liquid film boundaries are flexible, contract under the influence of ...

Femtosecond time resolved fluorescence upconversion was applied to determine directly the lifetime of the 1B~ + state of the carotenoid spheroidene in vitro in various polar and nonpolar solvents and in the LH-1 and LH-2 light-harvesting complexes of Rhodobacter sphaeroides at room temperature. The spheroidene IB + ~ 2A~internal conversion time varies from 150 to 250 fs in the solvents studied ...

In dynamic force spectroscopy, a (bio-)molecular complex is subjected to a steadily increasing force until the chemical bond breaks. Repeating the same experiment many times results in a broad distribution of rupture forces, whose quantitative interpretation represents a formidable theoretical challenge. In this study we address the situation that more than a single molecular bond is involved i...

Abstract Production of fresh pineapple fruit is dominated by the MD2 clone, while GP3 clone used as canned fruit. To be promoted fruit, has some defects, namely a less sweet taste and sensitivity to internal browning (IB) disorders. The clones need coatings, two might get responded differently. This study aimed effects chitosan-based coating mixed with palm stearin Aloe vera gel on qualities cl...

An algorithm is presented for the representation of macromolecular structures in terms of internal parameters (bond lengths, bond angles and dihedral angles). The algorithm ensures maintenance of data integrity and constancy when converting to and from a Cartesian representation. It is hoped that this algorithm will lead to large repositories of macromolecular strucure (including the PDB) being...
