We present a theoretical analysis of the dynamics one-dimensional spin-1/2 fermionic gas subject to weak two-body losses. Our approach highlights crucial role played by spin conservation in determination full time evolution. focus particular on that is initially prepared Dicke state with fully-symmetric wavefunction, band insulator, or Mott insulator. In latter case, we investigate emergence st...

Abstract The data on the dynamics of deterioration state water in sources supply, which is cause contamination drinking supply system, are presented. substantiation importance additional purification before entering production cycle given. influence pollutants present as a solvent composition products obtained by restoration dry canned food (powdered milk, cream and whey) shown. Studied such co...

serum albumin is the most aboundant protein in blood plasma. its two major roles aremaintaining osmotic pressure and depositing and transporting compounds. in this paper,albumin-methanol solution simulation is carried out by three techniques including montecarlo (mc), molecular dynamic (md) and langevin dynamic (ld) simulations. byinvestigating energy changes by time and temperature (between 27...

The dynamics of entanglement in `hybrid' non-unitary circuits (for example, involving both unitary gates and quantum measurements) has recently become an object intense study. A major hurdle toward experimentally realizing this physics is the need to apply \emph{postselection} on random measurement outcomes order repeatedly prepare a given output state, resulting exponential overhead. We propos...

background: the presence of lead in natural waters has become an important issue around the world. lead has been identified as a highly toxic metal that can cause severe environmental and public health problems and its decontamination is of utmost importance. the aim of this work was to evaluate the adsorption of lead (pb(ii)) on waste tea leaves as a cheap purification method. methods: in this...

background and objectives: recognizing the impurities of sugar beet and also comparing different methods of juice purification have shown that the chemical purification based on lime and carbon dioxide is really efficient and economic in the sugar industry. factories have to control and improve purification stages to achieve clear juice with high chemical purity, low color, minimum hardness, su...

introduction: polyclonal antibodies are required to be affinity purified. improved purification methods of polyclonal antibody provide an opportunity to pick the most purified immunoglobulins as a primary or secondary antibody in immunoassays that are included in many vaccine studies. two common techniques for purifying proteins is salt precipitation and chromatography purification. our work fo...

one of the most important aspects in recombinant biologic production, based on gmp rules, is the accuracy of final product quality control, especially assessment of host cell macromolecules contamination rate in final product. the purification requirement can be eliminated when the yeast cell containing the recombinant protein is used as a host cell. it is possibile that the final product conta...
