background: in intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. this study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended b...

objective: the purpose of this study was to evaluate the transverse strength of one brand of denture base material repaired with two autopolymerized acrylic resins with and without wire reinforcement. materials and methods: eighty samples (2.5×10×65 mm3) were fabricated and divided into five groups. the control group was left intact. groups b and d specimens were repaired with autopolymerizing ...

MANY types of micro-organisms have been tested by various workers for their ability to synthesize "vitamin B" (=complex). In such studies the organisms were grown in various nutrient media and the " vitamin B " was detected by its growth-promoting action or by curative tests on experimental animals such as the rat, the mouse or the pigeon. Thus "vitamin B " has been reported to have been produc...

A s local and international public health officials work to end the Ebola epidemic in West Africa, efforts to develop therapies and vaccines against the virus are ramping up. In late January, officials from the World Health Organization (WHO) announced that the Ebola epidemic had slowed. The WHO noted that for the first time since June 29, 2014, there were fewer than 100 new confirmed cases in ...

the microbial fuel cells (mfcs) are a kind of systems through which the anaerobic bacteriaalong with the oxidation of simple or complicated organic matter in the wastewater can generate the electricpower. this is a modern approach used in generation of the clean and renewable energy. in this research, two pilot laboratories of double-chamber microbial fuel cells were made. one of them contained...

The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

In this article various pipes used for transporting of gas are introduced and pros and cons of each one are elucidated. The pipes are categorized in three different subgroups including metallic, polymeric and metallic-wire reinforced polymeric pipes. Metallic-wire reinforced polymeric pipes are nominated as the best option for usage in high pressure pipelines transporting natural gas. As a resu...

El artículo tiene como propósito establecer un diálogo entre Watchmen, el cómic de Alan Moore y Dave Gibbons, su continuación televisiva, realizada bajo la dirección creativa Damon Lindelof. Este se establece sobre contenido político ambas obras, puntualmente en crítica al neoliberalismo régimen económico. Argumentamos que espacio temático narrativo tanto del serie es similar porque ambos const...

background: the aim of this study was to evaluate the response of common sized fiber-reinforced composites (frcs) to different deflections due to bending forces and comparing it with stainless steel (ss) wires. materials and methods: in this experimental study, two frc groups with 0.75 mm and 1.2 mm diameters (everstick ortho, stick tech, finland) and three ss groups with 0.016 × 0.022 inch, 0....

this paper presents a new method called vespiary regular hexagonal (vrh) model to calculate parasitic capacitance between conductor wire filaments of one turn of a coil and between conductor wires filament and liner and also total capacitance of n-turns having single-layers, multi-conductor wire filaments of the helix magneto cumulative generator (mcg) coil. the presented method is an analytica...
