The aim of this paper is description of the notion of the death for prisoners and the ways of deal with. They express indifference, coldness, inability to accept the blame, they have no shame and no empathy. Is it enough to perform acts verging on the death. In this paper we described mechanisms and regularities of selfdestructive behaviour in the view of the relevant literature? The explanatio...

accurate interpretation of radiographic images is dependent on viewing conditions. recently the number of radiology departments has been increased so it needs to use a workstation for reporting. the aim of this study was assess monitor performance and the effect of viewing conditions on object detection. this investigation aimed to quantify the effects of changes in box brightness and ambient l...

background: butterworth, gaussian, hamming, hanning, and parzen are commonly used spect filters during filtered back-projection (fbp) reconstruction, which greatly affect the quality and size accuracy of image. materials and methods: this study involved a cardiac phantom in which 1.10 cm thick cold defect was inserted into its myocardium wall and filled with 4.0 μci/ml (0.148 mbq/ml) 99mtc conc...

there are imaginative poets who have a look to nature and get astonished for their beauty and as if are observed for the first time.there are also some poets which are deeply inspired and get deeper insight by important factors of nature like color, sound and dynamism.dynamism is superior to the others. when poetic images are free of dynamism, they are deprived of beauty thus they are no more e...

the edges of an image define the image boundary. when the image is noisy, it does not become easy to identify the edges. therefore, a method requests to be developed that can identify edges clearly in a noisy image. many methods have been proposed earlier using filters, transforms and wavelets with ant colony optimization (aco) that detect edges. we here used aco for edge detection of noisy ima...

one of the challenging issues in managing the existing large digital image libraries and databases is content based image retrieval (cbir). the accuracy of image retrieval methods in cbir is subject to effective extraction of image features such as color, texture, and shape. in this paper, we propose a new image retrieval method using contourlet transform coefficients to index texture of the im...

This paper aimed to empirically deepen our understanding of the growing phenomenon negative consumer-brand relationships in Internet, striving investigate “who and why” consumers join anti-brand communities against top ten global brands. In particular, this study aims whether consumers’ profile affects they develop feelings or not, main reasons for their feelings. Methodologically, is based on ...

ct image quality has been affected by many factors such as kvp, ma, exposure time, alogorithm and section thickness. gantry tilt has the main role in visualization of the temporal bone anatomic structures. in this study, we tried to optimize these factors to determine the best gantry tilt. this study was performed on the human skull phantom and then extended to 15 patients. the phantom was made...

BACKGROUND There are no data comparing patient attitudes to sternotomy and thoracotomy scars following surgery for congenital heart disease (CHD). METHODS Two hundred and one patients with a scar from CHD surgery (105 sternotomy, 36 thoracotomy, and 60 both scars) had a structured interview to explore attitudes to their scar. RESULTS Comparable proportions of each group reported that they d...
