PURPOSE To evaluate the association of acromial morphology and subacromial impingement. METHODS Bilateral shoulder computed tomography was performed in 138 patients who received shoulder arthroscopy. Measured parameters included: acromial tilt (AT), modified acromial tilt (mAT), acromial slope (AS), acromiohumeral interval (AHI), lateral acromial angle (LAA), acromial index (AI), critical sho...

This paper presents the results of an extensive laboratory set tests aimed to study failure downstream shoulder highly permeable rockfill subjected overflow. The experimental research comprised testing 114 physical models by varying following elements: (i) median size uniform gravels (7 45 mm); (ii) configuration dam, i.e., upstream and shoulders crest or just shoulder; (iii) dam height (from 0...

conclusions generalized ligamentous laxity is an important predisposing factor for acute and chronic shoulder injuries in athletes. prescreening programs for beginners and rehabilitation shoulder programs for sports athletes at high risk are strongly recommended. results group a (with ligamentous laxity) consisted of 43 participants (36.4%) and group b (without ligamentous laxity) consisted of ...

Background and Purpose: The eastern part of the Czech Republic is afflicted by a decline in spruce stands. Forests stressed by drought are subsequently infested by honey fungus. Treating the root systems of spruce seedlings with a mycorrhizal preparation could present a certain possibility for protection against honey fungus. Mycorrhizal preparations are used in forestry, nursery management, ho...

background: frozen shoulder is resulting in limb disability and reduction of quality of life but the factors associated with patients’ disability and quality of life is not clear. to assess pain, disability, the quality of life and factors associated with them in patients suffering from frozen shoulder.  methods: we enrolled 120 patients (37 men and 83 women) with phase-ii idiopathic frozen sho...

kermanshah province is the main producer of various chickpea cultivars in iran. in this study a laboratory peg-tooth thresher was employed for chickpea threshing. the effect of cylinder speed (9, 12, 15 m/s), concave clearance (12, 14, 16 mm), feed rate (80, 160, 240 kg/h) and material moisture content (5, 10, 15% w.b.) was studied on percentage of grain damage, threshing efficiency and percent...

slope stability is one of the major and determiner parameters in the economy and safety of open pit mines. failure and consequently rupture of the slope caused no compensable economic and humanity losses. so, probability assessment of the further failure for presentation of damages and additional costs is of prime importance. in this research, stability analysis and probability assessment of th...

in this paper, under the condition that $k$ is concave, we characterize lacunary series in $q_{k}$ spaces. we improve a result due to h. wulan and k. zhu.
