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...
Methods Prospective cohort with 9 years of follow up. Inclusion criteria: diagnosis of asthma and at least one year of use of inhaled corticosteroids before enrollment. Every three months patients had a multidisciplinary evaluation and they received free medication (inhaled corticosteroids, long-acting and short-acting b-agonists) monthly. Spirometry was performed anually in a Koko spirometer a...
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...
Methods We carried out a retrospective analysis of incentive spirometry tests in recurrent wheezing children, aged 2-5 years, from our center, performed between September 2012 and March 2014. Lung function was assessed before and after 400 mg of inhaled salbutamol using a Jaeger spirometer v.4.65 (CareFusion). Wheezing symptoms, parental asthma, prematurity, passive smoking exposure, atopy and ...
In order to evaluate the effect of different training systems on growth, yield and fruit quality of greenhouse cucumber (Cucumis sativus cv. Gohar) this experiment was set out in a randomized complete block design with three replications. Treatments consisted of four training systems including twin-stem system (V-shape), modified twin-system, high-wire system and horizontal system (single-stem)...
Iridium-192 is one of the radioactive materials used in Brachytherapy in the treatment of tongue, lip, skin, prostate, breast and brain cancers. Different forms of Iridium-192 are used in Brachytherapy. This study was performed in order to produce Iridium-192 for the above mentioned uses in ...
wire-brushing is used for different purposes such as removing metal surfaces oxides, increasing surface brightness, improving fatigue properties and surface activation before coating. the wire-brushing severely scratches and stirs the metals in the surface layers, so that complicated metal flow gives rise to very large amount of plastic strain and increases dislocation density of the surface la...
