objective: the present study aimed to clarify dissociative symptoms in patients with schizophrenia and its association with negative and positive symptom of schizophrenia. methods: based on the 4th edition of diagnostic and statistical manual of mental disorders (dsm-iv) criteria, 80 schizophrenic subjects were randomly selected from patients who referred to the clinics of psychiatry hospital i...

background:  falls is worldwide health problem among older adults. different scales have been introduced related to falls, including falls efficacy scale (fes) and activity-specific balance scale (abcs). persian version of these scale needs to be assessed for internal consistency. the aim of this study was to evaluate the internal consistency of persian version of fes and abcs. methods:  in thi...

Generally, narcissus is propagated through vegetative methods, but due to their low yield their are not economical. This study was conducted to develop a suitable method for the production of somatic embryos and bulblets in Narcissus papyraceus cv. Shirazi. Bulb scales were placed on the MS medium supplemented with 2,4-D and BAP each at 0.0, 0.25, 0.5 or 1 mg/l concentrations to form somatic em...

The similarity jet of a linear scale-space is described in its most concise set of local and multi-local Euclidean invariants. The stability and (partial) equivalence of topologies on these invariants regardless additive uniform Gaussian noise is demonstrated.

Amorphological scale-space representation is presented based on a morphological strong filter, the levelings. The scale-properties are analysed and illustrated. From one scale to the next, details vanish, but the contours of the remaining objects are preserved sharp and perfectly localised. This paper is followed by a companion paper on pde formulations of levelings.

Using a procedure that eliminated repetition of identical items, thus avoiding order effects, we administered the Wechsler Adult Intelligence Scale (WAIS) and the WAis-Revised to 108 subjects. AH correlations between the two tests were significant and similar to those reported in the WAISR manual. For the group as a whole, verbal, performance, and full scale IQ scores on the WAIS-R were signifi...

This paper describes a method for the detection of tracking of elongated structures that is robust under changes of scale and orientation. This method is based on extending the concept of scale invariant natural interest points to include elongated ridge structures. An operator is proposed that directly detects ridge points and provides an estimation of their elongation and orientation. A track...

background: workplace safety has been a concern of workers and managers for decades. measuring safety climate is crucial in improving safety performance. it is also a method of benchmarking safety perception. objective: to develop and validate a psychometrics scale for measuring nurses' safety climate. methods: literature review, subject matter experts and nurse's judgment were used in items de...
