this experiment was carried out to investigate the effect of different substrate on growth and yield of gerbera flower. the experiment was performed using 10 treatments as fallow: fine sand, peat +fine sand (%25+%75), peat + fine sand ( %50 +%50), perlite + peat (%75 + %25), perlite + peat (%50 + %50), perlite + peat (%25 + %75), perlite + peat + expanded clay (%25 + %70 + %5), perlite + peat +...

BACKGROUND AND PURPOSE To explore relationships among gender, body size, neck size, and the diameters of the common carotid artery (CCA) and internal carotid artery (ICA). METHODS Using multivariate regression, the best predictors of sonographic diameters of CCA and ICA were determined based on age, height, weight, body mass index, body surface area, neck circumference, neck length, and blood...

Background In recent decades, the popularity of modular necks in total hip arthroplasty (THA) has increased since modular necks offer the potential to restore the patient's native anatomy, and thus improve stability. Unfortunately, modular necks are associated with higher complication rates, including implant fracture and modular junction corrosion with adverse local tissue reaction to metal de...

Screw-type fasteners are widely used to make connections between wood members or and steel connectors because they can tolerate the applied loads by withdrawal shearing. In this study, we evaluated resistances of screw-type analyzed effects lead-hole size, relative grain direction (tangential, radial, cross-sections) member, screw diameter, type, species. Two species, including domestic larch i...

Introduction: Obstructive sleep apnea (OSA) is a common disorder characterized by the repetitive collapse of upper airways during sleep, most likely in oropharyngeal region. Anatomical factors significantly contribute to disease development; however, heritability airway dimensions, which lead collapsibility airways, less known. In current study, we aimed quantify impact heritable and environmen...

Cervical teratomas are uncommon neoplasms, although the commonest neck tumors in newborns and infants. Presence of associated thyroid tissue often causes speculation as to the site of origin, ie, arising from within thyroid, adjacent soft tissue with secondary involvement of thyroid, or as innate part of a cervical teratoma. Twenty-eight cases of cervical teratomas were identified over 75 years...

objectives: presence/absence of cervical lymph node metastasis plays a critical role in prognosis and survival of patients with oral squamous cell carcinoma (scc). this study was designed to assess the diagnostic accuracy of computed tomography (ct) scan for detection of cervical lymph node metastasis in oral scc in comparison with histopathological analysis after neck dissection methods: in th...

introduction: there are significant gender differences in the epidemiology and presentation of cardiovascular diseases (cvds), physiological aspects of cvds, response to diagnostic tests or interventions, and prevalence or incidence of the associated risk factors. considering the independent influence of gender on early dire consequences of such diseases, this study was conducted to investigate...

a 4-month-old boy was admitted to our hospital following an unsuccessful attempt at interventional repair of aortic coarctation via the right carotid artery, which seemed to have given rise to the formation and growth of a cervical mass overlying the entry site. despite the initial anticipation of difficulty during intubation due to the pressure effect of the mass, anesthesia progressed unevent...
