Burns are one of the most widespread traumatic injuries. The number victims burns worldwide is steadily increasing. All this determines search for new highly effective methods treating burned patients. (1.2.4.5.20.)The main requirements wound healing creation an optimal microenvironment healing, high absorption capacity exudate, ability to prevent ingress microorganisms, sufficient permeability...

Problem statement: Membrane computing has structural resemblance with the cell structure. This characteristic provides the versatility in the modeling of biological processes. Approach: This study was carried to discuss the membrane computing formalism in modeling biological processes by analyzing two examples: Photosynthesis in chloroplast and Sodium-Potassium exchange pump. Results: The model...

Problem statement: Most of the biological systems have been hierarchical in structure with processes interacting between different compartments. Membrane computing formalism has provided modeling capabilities in representing the structure of biological systems. Approach: This study was carried to investigate the modeling of a multi-compartment biological system by using membrane computing forma...

Nuclear magnetic resonance (NMR) spectroscopy, and particularly solid-state NMR spectroscopy, is a method of choice to study the structure and dynamics of both the lipid and the protein components of model and biological membranes. Different approaches have been developed to study these systems in which the restricted molecular motions result in broad NMR spectra. This contribution will first p...

A cross-flow membrane was coupled to a chemostat to create an anaerobic membrane bioreactor (MBR) for biological hydrogen production. The reactor was fed glucose (10,000 mg/L) and inoculated with a soil inoculum heat-treated to kill non-spore-forming methanogens. Hydrogen gas was consistently produced at a concentration of 57-60% in the headspace under all conditions. When operated in chemostat...

Several Membrane Bioreactor (MBR) facilities have been constructed with the intent of providing Enhanced Biological Phosphorus Removal (EBPR), and several additional such plants are being designed and constructed. Full-scale plant information is now available for process designers to better understand the unique design and operating issues associated with the incorporation of EBPR designs in MB...
