In order to prepare intracellular substances from microorganisms the barrier of the cell envelope has to be disrupted. Since this barrier is usually very resistant, the methods available for the preparation of substances with unstable activity are restricted due to the inactivation occasioned by some disintegration processes. Some methods, usually applying physico-mechanical shearing stress, ar...

conclusions the results clarified a deep perception of participants’ experiences after disaster. the path of life recovery after disasters involves participants’ striving to achieve a comprehensive health recovery, which starts with the need for all-inclusive health recovery as a main concern; this is the motivator for a responding strategy. this strategy is participatory, and the process is pr...

various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. the objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...

background: each member of society needs suitable services in recovery wards including patient safety in the ward, improvement and taking care of patients after surgery and anesthesia in order to decrease undesirable evidences, mortality and morbidity. the special characteristic of recovery cares is nursing cares. the nurse is one of the effective members of a health group and her/his effective...

An experiment was conducted on eight weak and anaemic goats revealed pale conjunctivae, increased heart rate, rough hair coat, dullness and depression. The haematology showed significantly decreased haemoglobin (7.37±0.16 g %), packed cell volume (PCV)(23.37±0.56%),total erythrocyte count (TEC)(8.12±0.18 million/cumm), mean corpuscular haemoglobin (MCH) (9.10±0.30 pg) and mean corpuscular volum...

for the purpose of increasing the permeability to oxygen and equilibrium water content in contact lenses, polar copolymers with nonionic monomers such as 2-hydroxyethle methacrylate(hema) is used. by adding the polar monomers to (hema), the permeability to oxygen and equilibrium with water content is increased and also the absorption of proteins on lens surface is changed. in this research, the...

recovery is a part of disaster management cycle during which repair and reconstruction takes place, and individuals, groups, and communities retake what they have lost and ideally the risk of future incidents reduces. life recovery is a subjective and multidimensional issue influenced by various factors, whereas valid measurable indicators in evaluating the recovery after disasters are helpful....
