Computational fluid dynamics (CFD) is a powerful numerical tool that is becoming widely used to simulate many processes in the industry. In this work study of the stirred tank with 7 types of concave blade with CFD was presented. In the modeling of the impeller rotation, sliding mesh (SM) technique was used and RNG-k-ε model was selected for turbulence. Power consumption in various speeds in th...

ABSTRACT Soils are highly variable across landscapes, which can be assessed and characterized according to scale, as well fractal multifractal concepts of scale. Thus, the objective this study was analyze multifractality penetration resistance (PR) vertical profiles from different slope forms (concave convex). The experimental plot incorporated 44.75 ha, PR measured at 70 sampling points in 0-0...

Let F be a class of functions on a probability space (Ω, μ) and let X1, ..., Xk be independent random variables distributed according to μ. We establish an upper bound that holds with high probability on supf∈F |{i : |f(Xi)| ≥ t} for every t > 0, and that depends on a natural geometric parameter associated with F . We use this result to analyze the supremum of empirical processes of the form Zf...

Shoulder pain occurs commonly in food service workers (FSWs) who repetitively perform motions of the upper limbs. Myofascial trigger points (MTrPs) on the upper trapezius (UT) are among the most common musculoskeletal shoulder pain syndromes. This study determined the psychological, posture, mobility, and strength factors associated with pain severity in FSWs with UT pain due to MTrPs.In this c...

Based on historical data landslide events, Damer District is an area prone to landslides in Southwest Maluku Regency. One of the first steps mitigating map areas that have potential for landslides. The purpose this study was determine spatial distribution landslide-prone District, This uses SMORPH method identify and classify based matrix between shape slope angle slope. resulted 4 levels areas...

BACKGROUND Arm elevation is composed of glenohumeral and scapulothoracic motion. Many reports have addressed changes of scapular position across a spectrum of shoulder disease. However, no study has examined changes in scapular position after reverse total shoulder arthroplasty (RTSA). The purpose of this study was to evaluate the changes in scapular position after RTSA compared to patients' co...

Down-sloped or hooked acromion morphologies may cause bony encroachment on the soft tissues of the subacromial space, predisposing to shoulder impingement syndrome. Of the latter, a hooked or Type III acromion (T3A) has also been linked to rotator cuff (RC) pathology. However, as bony acromial impingement is typically thought to occur over the age of 40, its occurrence in younger shoulder athle...

methods a cross sectional survey of 156 archers (m = 91, f = 65) mean age = 20.27 ± 2.31 (range 15 - 28 years) was conducted during all india inter university archery tournament 2013. study consisted of two parts - schedule interview and clinical examination of both shoulders. t test, odds ratio and cross tabulation with chi square (χ2) test were the tool of statistical analysis. results the po...

Lemma 1 In the (t, g) policy space: (i) The ideal policy of py is (t = 1, g = g∗(1)) and the ideal policy of ry is (t = 0, g = 0) if θ > w wh and otherwise it is (t = t ∗, g = t∗w θ ) for some t∗ ∈ (0, 1). The indifference curves of ry and py are weakly concave and differentiable. For all t0 ∈ [0, 1], an indifference curve of ry(py) that goes through (t0, 0) lies on or above a line that goes th...

An analysis of arm movements involving forward projection of the hand in order to reach for and grasp a target at different orientations is presented. The reaching movements required shoulder flexion, elbow extension, and wrist pronation or supination. The relation between elbow and shoulder instantaneous angular position proved to be consistent from trial to trial of each task, independent of ...
