Introduction: Intraoperative radiotherapy is a radiotherapy technique in which a high single fraction of radiation dose is delivered to the patient after surgery and Concurrent with anesthesia time. The most frequent method for IORT implementation is Intraoperative electron radiotherapy (IOERT), in which, some dedicated and high dose per pulse electron accelerators are employe...

the photocatalytic activity of nano-tio2 has been used in inactivation of microorganisms, mainly in the form of suspension in a liquid or partially in an immobilized system. using advanced oxidation processasa new approach has been used in the purification of water and wastewater. in this research, the systems of suspended (0.1 g/l) and immobilized nano-tio2 in the cement bed (0.1-2%) under a 1...

Abstract Lattice structures are 3D open topologically ordered geometries that repeat an elementary cell in a predefined space. Struts connected specific nodes define the cell. typical represent design freedom unlocked by additive manufacturing (AM) and unachievable with traditional processes. By tuning morphometric parameters of cell, its mechanical response can be significantly altered. Becaus...

in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...

While much of additive manufacturing (AM) research is focused on microstructure, material properties, and defects, there less in regards to understanding how well the part coming out machine matches 3D model it based on, as what are key process parameters an engineer needs care about when they optimizing for AM. The purpose this study was understand dimensional accuracy electron beam powder bed...

PURPOSE To evaluate the outcomes of high-risk prostate cancer patients treated with biologically effective dose (BED) ≥ 220 Gy of high-dose radiotherapy, using low-dose-rate (LDR) brachytherapy in combination with external beam radiotherapy (EBRT) and short-term androgen deprivation therapy (ADT). MATERIAL AND METHODS From 2005 to 2013, a total of 143 patients with high-risk prostate cancer w...

These kickers will be used to make fast dipoles and quadrupoles which are driven by sharp risetime pulsers to provide precision beam manipulation for high current kA electron beams. This technology will be used on the 2 axis of the DARHT linac at LANL. It will be used to provide 4 micropulses of pulse width up to 120 nsec. selected from a 2 μsec., 2kA, 20MeV macropulse. The fast pulsers will ha...

background and objectives: constant monitoring of healthcare organizations’ performance is an integral part of informed health policy-making. several hospital performance assessment methods have been proposed in the literature. pabon lasso model offers a fast and convenient method for comparative evaluation of hospital performance. this study aimed to evaluate the relative performance of hospit...
