Crane Hooks are highly liable components and are always subjected to failure due to the amount of stresses concentration which can eventually lead to its failure. To study the stress pattern of crane hook in its loaded condition, a solid model of crane hook is prepared with the help of ABAQUS software. Real time pattern of stress concentration in 3D model of crane hook is obtained. The stress d...

The bacterial flagellar hook is a short, highly curved tubular structure connecting the basal body as a rotary motor and the filament as a helical propeller to function as a universal joint to transmit motor torque to the filament regardless of its orientation. This highly curved form is known to be part of a supercoil as observed in the polyhook structure. The subunit packing interactions in t...

Coordination between different motor centers is essential for the orderly production of all complex behaviors, in both vertebrates and invertebrates. The current study revealed that rhythmic activities of two feeding structures of the pteropod mollusk Clione limacina, radula and hooks, which are used to extract the prey from its shell, are highly coordinated in a phase-dependent manner. Hook pr...

BACKGROUND Baseball players are susceptible to a number of specific upper extremity injuries secondary to batting, pitching, or fielding. Fractures of the hook of hamate have been known to occur in batters. The purpose of this study is to present our experience with the surgical management of hook of hamate fractures and their short-term impact on the playing capability of competitive baseball ...

Over the past few decades, magnetoreception has been discovered in several species of teleost and elasmobranch fishes by employing varied experimental methods including conditioning experiments, observations of alignment with external fields, and experiments with magnetic deterrents. Biogenic magnetite has been confirmed to be an important receptor mechanism in some species, but there is ongoin...

This study aimed to determine the impact of hook and bait type on catch composition per unit effort. Effects types composition, effort (CPUE), length weight distributions in demersal longline fishery were determined by experimental surveys sets Aegean Sea. A total 12 samplings corresponding 4800 fishing performed between April 2014 September 2014. Two types; sardine (Sardina pilchardus) grooved...

We completely characterize the appearance of Schur functions corresponding to partitions of the form ν = (1a, b) (hook shapes) in the Schur function expansion of the plethysm of two Schur functions, sλ[sμ] = ∑ ν aλ,μ,νsν . Specifically, we show that no Schur functions corresponding to hook shapes occur unless λ and μ are both hook shapes and give a new proof of a result of Carbonara, Remmel and...

The bacterial flagellar hook is a short and uniquely curved tube that connects the basal body to the filament. Hook length is controlled at 55 nm on average by a soluble protein FliK in Salmonella enterica serovar Typhimurium. The N-terminal segment of FliK responsible for measuring the hook length is considered to be intrinsically disordered. Here, we show by high-speed atomic force microscopy...

AO clavicular hook plate fixation provides more rigid fixation and good bony union rates for Neer type II distal clavicular fractures. However, the hook may cause rotator cuff tears and subacromial impingement, which adversely affect the clinical results. T-plate fixation is another surgical method of treatment for unstable clavicle fractures, and its clinical efficacy has been demonstrated. Th...

Recently, a simple proof of the hook length formula was given via the branching rule. In this paper, we extend the results to shifted tableaux. We give a bijective proof of the branching rule for the hook lengths for shifted tableaux; present variants of this rule, including weighted versions; and make the first tentative steps toward a bijective proof of the hook length formula for d-complete ...
