هدف: پژوهش حاضر باهدف بررسی رابطه اختلال استرس پس از سانحه با علائم کندی زمان شناختی در افراد نقص توجه-بیش فعالی تأکید بر نقش تعدیل‌کننده‌ای تجربه کودک‌آزاری و واسطه‌ای اجتناب تجربه‌ای صورت گرفت. روش: این همبستگی، جامعه آماری شامل 312 نفر مبتلایان به دامنه سنی 18 تا 60 سال شهر اصفهان بود که مقیاس درجه‌بندی ADHD بزرگسالان بارکلی (BAARS) دارای نمرات 1+=Z بودند. سپس به‌منظور سنجش تعدیل‌کنندگی کودک...

ارزیابی خشک‌سالی، ازنظر زمانی و مکانی، برای برنامه‌ریزی‌های کاهش خسارات در استان کردستان اهمیت بسیاری دارد. این تحقیق، از شاخص بارش استانداردشده همچنین، پوشش گیاهی بارزشدة استخراجی تصاویر ماهواره‌ای، به‌منزلة پارامتر تعیین‌کنندة استفاده شده است. به‌این‌منظور، داده‌های آماری ایستگاه‌های هواشناسی شامل حداکثر دمای ماهیانه، مجموع سالیانه نیز سنجندة مادیس به‌کار رفته با مقایسة پارامترهای میانگین سال...

Transcutaneous energy transfer system (TETS) is one of the methods to supply electric power an assisted heart. In this study, we analyzed effects fields in body on biological tissues around TETS. Using electromagnetic field simulator, tissue models consisting Dry-Skin, Wet-Skin, Fat, and Muscle were fabricated. When frequency was fixed at 400 kHz transmission distance 20 mm, analysis conducted ...

On July 23, 2001, new safety limits for occupational exposure to electromagnetic fields (EMF) were introduced in Poland. The limits have been based on the analysis of international recommendations, e.g., ICNIRP (1998), WHO (1998), IEEE standard (1999), drafts of European standards (ENV 1995), and a critical review of the world literature on the biological effects of EMF and health effects of ex...

─ In this study, electric field strength (E) levels were measured on Ondokuz Mayıs University’s Kurupelit Campus and Faculty of Medicine Hospital in Samsun, Turkey between years 2013-2015. 840 short term and two long term measurements were performed using PMM–8053 and SRM–3006 at 60 different locations of which 30 were on both the campus and hospital. The results show that the measured E levels...

The aim of this study is to investigate the levels of electric and magnetic power frequency fields at 8 electrical transformation stations in the North-East counties of Romania and to check their compliance with standards. Spot measurements were carried out on both electric and magnetic fields under overhead conductors of 110-, 220- and 380-kV installations. The magnetic field levels were sever...

This paper identifies uncertainties and problems in the practical application of the ICNIRP low frequency basic restriction on current density. This quantity should be averaged over a cross-section of 1 cm(2) perpendicular to the current direction. The rationale and the sensitivity of the current density average are investigated. There are difficulties in finding a square centimetre of spinal c...

The Advisory Group on Non-ionising Radiation (AGNIR) 2012 report forms the basis of official advice on the safety of radiofrequency (RF) electromagnetic fields in the United Kingdom and has been relied upon by health protection agencies around the world. This review describes incorrect and misleading statements from within the report, omissions and conflict of interest, which make it unsuitable...

This paper presents occupational skin exposure to solar ultraviolet radiation (UVR) of 122 Polish outdoor workers in spring and summer. In 65% of the cases, it was significant and exceeded 10 standard erythema doses (SED) during a work shift. The results provided grounds for (a) modifying hazard assessment based on the skin exposure factor proposed by the International Commission on Non-Ionizin...
