Bacterial biofilms correspond to surface-associated bacterial communities embedded in hydrogel-like matrix, in which high cell density, reduced diffusion and physico-chemical heterogeneity play a protective role and induce novel behaviors. In this review, we present recent advances on the understanding of how bacterial mechanical properties, from single cell to high-cell density community, dete...

Abstract Porous mullite ceramics were prepared from mixtures of Egyptian kaolinite-clay and calcined α-alumina powder. The effects two methods compaction as well types binder investigated. influence sintering temperature on the physical properties, crystalline phase, compressive strength microstructure was studied. Mullite bodies processed by uniaxial pressing utilizing 15wt. % water at 1500°C ...

The purpose of the study is to and analyze physical mechanical properties seed pile fodder crops. results determining physico-mechanical crops obtained in combing clover plants with a comb drum harvesting machine are presented. basic principles methods classical mechanics, mathematical analysis, statistics were used this study. It was found that stiffness stems at humidity 40-60% range 0.07-0.0...

Very little is known about the nature of the tissue fluid in the oedema of pregnancy toxaemia. Most investigators (Dieckmann, 1942; Taylor, Warner, and Welsh, 1939; Chesley and Chesley, 1943) believe that the abnormal water balance in this condition is caused by a combination of several factors, both mechanical and physico-chemical in nature. There is general acceptance of the fact that the oed...

Twenty one samples of argan oil of different geographical origin (Tidzi, Tamanar, Benaiznassen, Ait mzal, Ait Baha, Ighrem, Aoulouz) and/or prepared following a different process (traditional, mechanical, or industrial) were collected and their physico-chemical properties analyzed. Sample acidity was found between 0.14 and 1.40%, unsaponifiable matter between 0.34 and 0.79%, saponification valu...

A comprehensive database named, protein ligand interaction database (PLID), is created with 6295 ligands bound to proteins extracted from the protein data bank (PDB). This is by far the most comprehensive database of physico-chemical properties, quantum mechanical descriptors and the residues present in the active site of proteins. It is a publicly available web-based database (via the Internet...

Magnetic nanocomposites are an important class of advanced functional materials on the basis of a magnetic material and a matrix. To achieve unique mechanical, physical, chemical, and biomedical properties, one must be able to tailor only the surface structures of a nanoparticle. This requires the deposition of ultrathin and uniform films using the possibility offered by cold-plasma polymerisat...
