Isolated barred galaxies evolve by redistributing their internal angular momentum, which is emitted mainly at the inner disc resonances and absorbed mainly at the resonances in the outer disc and the halo. This causes the bar to grow stronger and its pattern speed to decrease with time. A massive, responsive halo enhances this process. I show correlations and trends between the angular momentum...
The purpose of this study was to examine the influence of two different bar diameters on neuromuscular activation and strength. The bar diameters used reflected a standard Olympic bar (28 mm (1.1 inch); THIN) and a larger fat bar (51 mm [2 inch]; THICK). Eighteen healthy men (age 25.06 1 years) were assessed for their maximal voluntary contraction (MVC) during a unilateral isometric bench press...
For decades, the grand-design SAB spiral galaxy NGC 5248 has been postulated to host a short bar of semimajor axis 22 (1.6 kpc). From dynamical and morphological arguments, however, we argue that its spiral structure is being driven by a large-scale bar whose corotation radius lies at ∼115 (8.6 kpc). Our estimate is based partially on a deep R-band image, which reveals that the feature previous...
مقدمه: به علت مشکلات دنچرها، امروزه اوردنچرهای متکی بر ایمپلنت رواج یافتهاند. به رغم موفقیت بالای ایمپلنت، از دست رفتن ایمپلنت هنوز معضل اساسی است. افزایش نیروی وارد بر ایمپلنت فاکتور مهم تحلیل استخوان و از دست رفتن ایمپلنت میباشد. این مطالعه با آنالیز اجزای محدود اوردنچرهایی با سه ایمپلنت، به بررسی بهترین طراحی و ترکیب اتچمنت که باعث حداقل استرس در استخوان آلوئول شود، پرداخته است. مواد و روش...
The interaction between cosmic rays and the gravitational wave bar detector NAUTILUS is experimentally studied with the aluminum bar at temperature of T=1.5 K. The results are compared with those obtained in the previous runs when the bar was at T=0.14 K. The results of the run at T = 1.5 K are in agreement with the thermo-acoustic model; no large signals at unexpected rate are noticed, unlike ...
The main combinatorial result in this article is a classification of bar partitions of n which are of maximal p-bar weight for all odd primes p ≤ n. As a consequence, we show that apart from very few exceptions any irreducible spin character of the double covers of the symmetric and alternating groups vanishes on some element of odd prime order.
We reformulate the bar recursion and induction principles in terms of recursive and wellfounded coalgebras. Bar induction was originally proposed by Brouwer as an axiom to recover certain classically valid theorems in a constructive setting. It is a form of induction on nonwellfounded trees satisfying certain properties. Bar recursion, introduced later by Spector, is the corresponding function ...
The expression level of bar, which encodes phosphinothricin acetyltransferase (PAT), was correlated with the inviability of barley hybrids between 20 Golden Promise-derived transgenic lines (Ds-bar lines) and a specialized genetic marker stock, Oregon Wolfe Barley Dominant (OWBD). Each Ds-bar line was homozygous for a modified maize Ds element that encoded bar and that had been delivered via tr...
This study compared the values of bar-peak force (PFBar) and power (PPBar), body-peak force (PFBody) and power (PPBody) and bar-mean propulsive power (MPPBar) in different jump-squat (JS) conditions: unloaded condition (UC); bar-loaded condition (BLC) and optimum bar-MPP condition (OBC). Twenty-five soccer players performed the JS using a bar with negligible mass (UC), using the Smith-machine b...
Critical insights on galaxy evolution stem from the study of bars. With the advent of high redshiftHST surveys that trace bars in the rest-frame optical band out to z ∼ 1, it becomes increasingly important to provide a reference baseline for bars at z ∼ 0 in the optical band. We present results on bars at z ∼ 0 in the optical and near-infrared bands, based on 180 spirals in the OSUBSGS survey. ...
