background: according to the growth of photocopier usage in workplaces, the potential risk of occupational exposure to the airborne chemicals has been raised up. hence, monitoring the photocopy worker's respiratory functions seems to be necessary. we aimed to evaluate the respiratory health on photocopy and printing workers so that a reliable description can be made about their occupational hyg...

Endovascular management concepts have recently emerged as valuable treatment options for both simple and complex disorders involving both the distal arch and descending thoracic aorta. With growing use of endovascular stent-grafts the technique has generated broad interest. Nevertheless, an ideal device for different thoracic aortic conditions is not available yet. After initially using the fir...

Conventional polymer multielectrode arrays (MEAs) have limitations resulting from a high Young’s modulus, including low conformability and gaps between the electrodes and neurons. These gaps are not a problem in soft tissues such as the brain, due to the repopulation phenomenon. However, gaps can result in signal degradation when recording from a fiber bundle, such as the spinal cord. Methods: ...

PURPOSE This study examined whether any of a series of segmental and whole-word measures of articulatory competence captured more of the variance in impressionistic ratings of severity of involvement in speech delay. It also examined whether knowing the age of the child affected severity ratings. METHOD Ten very experienced speech-language pathologists rated severity of involvement from conve...

A comparative study was performed on the initial and final bacillary indexes of 213 multibacillary leprosy patients who received 12 doses (Group 1: 128 patients) or 24 doses (Group 2: 85 patients) of multidrug therapy (MDT/WHO) to measure the effectiveness of the two regimens. All patients were evaluated at treatment baseline, 12 months, and 24 months. The reduction in bacillary levels and mean...

In order to evaluate the graduates attending second-round examination objectively, this study established graduate second-round examination evaluate system based on Analytic Hierarchy Process (AHP) and Fuzzy comprehensive evaluation method. Evaluation indexes in the system included knowledge structure, scientific research ability and comprehensive quality of graduates attending second-round exa...

This paper demonstrates the advantage of combining a ranked output from a fulltext index and another from an index generated using generic summary texts. Our main ndings are as follows: (1) The combination of a fulltext-based run and a summary-based run can signi cantly outperform either alone, especially when the fulltext evidence is emphasized. (2) The primary role of the summary index in the...

the aim of this paper is to examine and analyze the spatial distribution of population in cities of the southern coastal region of iran by using common models and techniques in the field and to study the trends of evolution in a time period of 40 years (1345-1385). models used in the study can be classified into three main groups. the first group is the primate city indexes (including jefferson...
