We describe a concept for a target station surrounding a pion production/capture system capable of accepting a 4-MW proton beam. The target system consists of a free mercury jet immersed in a high-field solenoid magnet capture system. The shielding required for the protection of the superconducting solenoid coils is a major consideration. Additional infrastructure required for the target system...

Perishability of blood products as well as uncertainty in demand amounts complicate the management of blood supply for blood centers. This paper addresses a mixed-integer linear programming model for blood platelets production planning while integrating the processes of blood collection as well as production/testing, inventory control and distribution. Whole blood-derived production methods for...

The capture efficiency of the small aerosol particle is strongly influenced by the structure of fibrous layers. This study presents particle deposition and dendrite formation on different arrangements of binary fibers. 2-D numerical simulation is performed using the open source software of OpenFOAM. In the instantaneous filtration of a single fiber, obtained results are in good agreement with th...

background hepatitis b virus (hbv) covalently closed circular dna (cccdna) served as a vital role in the life cycle of the virus and persistent infection. however, specific and quantitative methods for cccdna detection have not been available. objectives our aim was to develop and primarily evaluate a quantitative method for hbv cccdna based on magnetic capture hybridization and quantitative pc...

Carbon Capture and Storage is being actively developed for deployment in fossil fuel power stations in an attempt to reduce future emissions of CO2 due to concerns about climate change. The deployment of this technology will cause an inevitable reduction in the overall efficiency of any electricity generation plant leading to an increase in demand for the fossil fuels used to power the generati...

background and objectives: a single reactive igg anti-dengue virus elisa test in the absence of igm antibodies or ns1 antigen may denote current infection or past exposure to the virus. to determine whether igg index value can be used to identify true current dengue infection we conducted a prospective observational study. materials and methods: suspected dengue patients (n =1745) were tested i...

In the Next Linear Collider design [1], the positron capture system includes a positron production target, followed by a short solenoid with a strong magnetic field (flux concentrator), a 250 MeV linac with solenoidal focusing, a 1.73 GeV linac with quadrupole focusing and an energy compressor system before injection into the positron pre-damping ring (see Fig. 1 for initial part of collector)....

Production of human proteins in Pichia pastoris has significant advantages. However, there is still need for improvement in various stages of its downstream processing like clarification and purification. In fact downstream processes are usually the most critical part of production of biotech products. This work aimed to evaluate the effect of two steps added to the downstream processes ...

avian leukosis viruses (alvs) cause different types of tumours in poultry and can affect the health and egg production of the birds. to investigate the presence of the virus in chicken layer flocks in shiraz, 222 egg albumen from local layer breeder (25 eggs), local layer grand parent (30 eggs), broiler breeder (60 eggs), commercial layer (46 eggs) and broiler grand parent (61 eggs) were tested...
