BACKGROUND Many surgeries are performed under spinal anesthesia. Inexperienced practitioners may find it difficult to obtain subarachnoid access. OBJECTIVES This study aimed to examine the relationship between patients' anthropometric characteristics and depth of spinal needle insertion to the subarachnoid cavity. PATIENTS AND METHODS 385 patients with ASA class I - II, aged 18 - 65 years a...

These High resolution satellite data with metadata information is used to extract the height of the building using shadow. Proposed approach divides into two phases 1) rooftop and shadow extraction and 2) height estimation. Firstly the rooftop and shadow region were extracted by manual/ automatic methods using Example – Based and Rule – Based approaches. After feature extraction next step is es...

Wave propagation is used as an advanced tool of determining elastic properties of rocks. In spite of being cheap and non destructive tests of rock mechanics, due to its modernity method is not yet replacing the traditional dear and destructive tests. In order to pave ways of replacing this test and making best use of it all effective factors of such method are to be assessed. One fundamental fa...

OBJECTIVES The aim of this study was to compare nostril height, width, collumelar length, interalar distance and nostril symetry between unilateral complete cleft lip/palate patients undergoing nasoalveolar moulding (NAM) and incomplete cleft lip patients/palate with no need of presurgical moulding before and after cheiloplasty with primary nasal correction. Our study group included 18 patients...

We investigated the relationships among serum testosterone levels, body fat and muscle mass distribution in women with polycystic ovary syndrome (PCOS). Subjects were 67 women with PCOS (mean age +/- standard deviation, 28.8 +/- 6.6 years). Baseline characteristics included age and height. Trunk-leg fat ratio and trunk-leg muscle ratio were assessed with dual-energy x-ray absorptiometry. Serum ...

Light regimes vary significantly within small forest openings, rangingfrom full sunlight to total shade, and they may affect the establishment and early growth of oak seedlings. We designed modified shadehouses to simulate the complex light conditions within forest openings and tested the effects of daily photosynthetically active radiation (PAR), time of direct light exposure, and the ratio of...

Abstract The undrained shear strength (Su) and cohesion (Cu) of cohesive soils are frequently determined using an unconfined compression test. However, the test results heavily dependent on specimen size. This causes uncertainty in geotechnical analyses, constitutive models, designs by overestimating or underestimating soils. Therefore, study aims to assess effect height-to-diameter ratio compr...
