background exposure to the excessive levels of occupational noise is one of the principal harmful agents affecting the workers’ health. this study aimed to investigate the relationship between the occupational noise exposure and the hearing loss caused by working in small-scale service industries in the city of damavand, close to the metropolitan capital city of tehran, iran. methods this descr...

background: diabetes mellitus (dm), simply known as diabetes, refers to a group of metabolic diseases in which there are high blood sugar levels over a prolonged period. in this study, the feasibility and safety of intravenous transplantation of very small embryonic like stem cells (vsels) were investigated for diabetes repair, and finally the migration and distribution of these cells in hosts ...

the purpose of this article is to investigate the uniqueness of meromorphic functions sharing five small functions on annuli.

the asia-pacific region generates over half of global economic activity (54.2%) and about 43.7% of global trade, and is the most dynamic region in the global economy. at the core of this is an increasingly dynamic, vibrant and entrepreneurial small-medium sized enterprise sector. advances in information and communications technology, market liberalisation and moves towards closer regional econo...

this paper presents the thermal vibration analysis of double-layer graphene sheet embedded in polymer elastic medium, using the plate theory and nonlocal continuum mechanics for small scale effects. the graphene is modeled based on continuum plate theory and the axial stress caused by the thermal effects is also considered. nonlocal governing equations of motion for this double-layer graphene s...

background: accurate small radiation field dosimetry is essential in modern radiotherapy techniques such as stereotactic radiosurgery (srs) and intensity modulated radiotherapy (imrt). precise measurement of dosimetric parameters such as beam profile, percentage depth doses and output factor of these beams are complicated due to the electron disequilibrium and the steep dose gradients. in the p...

the use of more competitive species and cultivars in small grain cereal production may help to develop production systems that require less herbicide. this study was designed to identify root and shoot characteristics of cereal seedlings that would allow distinguishing the more competitive (mc) cultivars from the less competitive (lc) ones. two growth cabinet trials were conducted using four cr...

eosinophilic gastroenteritis is a rare disease of unknown etiology. it is characterized by eosinophilic infiltration of the gastrointestinal tract wall (especially stomach and small bowel). symptoms and signs of this disease depend on the involved layer of gastrointestinal tract. hereby, we are presenting a patient with abdominal pain since one month ago that aggregated with meals. the patient ...

gastrointestinal (gi) bleeding in pediatric patients has several causes. vascular malformation of the small bowel is a rare disease leading to pediatric gi bleeding. to our knowledge, few reports describe ultrasound and computed tomography findings of venous malformations involving the small bowel. we present a case of long-segmental and circumferential vascular malformation that led to gi blee...

objective: the aim of the present study was to retrospectively evaluate small-diameter (3.3 mm) straumann® dental implants placed in the maxilla or the mandible over a period of 5 years in function. materials and methods: twenty- eight partially edentulous patients received a total of 48 implants over a 5-year period. after the standard healing period (3 to 6 months), the implants were restored...
