Kilohertz and Low-Frequency Electrical Stimulation With the Same Pulse Duration Have Similar Efficiency for Inducing Isometric Knee Extension Torque …

2017

International audience; Objective To test the hypotheses that, as compared with pulsed current with the same pulse duration, kilohertz frequency alternating current would not differ in terms of evoked-torque production and perceived discomfort, and as a result, it would show the same current efficiency.Design A repeated-measures design with 4 stimuli presented in random order was used to test 25 women: (1) 500-microsecond pulse duration, (2) 250-microsecond pulse duration, (3) 500-microsecond pulse duration and low carrier frequency (1 kHz), (4) 250-microsecond pulse duration and high carrier frequency (4 kHz). Isometric peak torque of quadriceps muscle was measured using an isokinetic dyna…

Effects of whole-body vibration exercise on muscular strength and power, functional mobility and self-reported knee function in middle-aged and older…

2013

Abstract Background Whole-body vibration training using vertical-vibration machines is called “acceleration training” (AT). The purpose of this study was to elucidate the effect of AT on lower-limb muscular strength and power, functional mobility and self-reported knee function in middle-aged and older Japanese women with knee pain. Methods Thirty-eight middle-aged and older Japanese women (aged 50–73 years) with knee pain were divided into two groups: (1) the AT group (n = 29) engaged in AT three times per week for eight weeks, and (2) the control group (C group, n = 9). The AT program consisted of flexibility training, strength training of mainly the quadriceps and surrounding muscles and…

Integrating business start-up indicators in the flexicurity concept to cover the alternative forms of employment

2016

The flexicurity concept created in the Netherlands and Denmark in the early 1990s has become the main stepping-stone in improving the performance of labour markets across the European Union Member States. The European Commission has therefore taken a leading role on broader flexicurity concept development and creation of the data analysis methodology. However, the analysis proposed by the European Commission Joint Research Centre on flexicurity indicators in 2010 only partly includes business start-ups as a flexible form of employment. This research starts the discussion on whether additional indicators should be integrated in the flexicurity analysis, because of the rising need for employm…

Joint Venture, an Alternative for Knowledge Learning

2012

Joint venture as a form of business cooperation is a valid alternative for acquiring external knowledge and particularly so when it is unavailable on the market. Joint venture constitutes an interesting instrument for learning in firms that belong to high technology sectors; it not only enables access to learning but can also help its assimilation and even its subsequent application to new uses. To analyze this learning, we focus on the elements that make it up, the nature of transferred knowledge, communication between partners, the motivation of the partner to learn, and lastly, the context in which this occurs, such as the type of organizational structure of the partner firm. We obtained…

Einsatzmöglichkeiten der MR-Arthrographie bei Erkrankungen des Schultergelenkes

1994

In a prospective study possible indications for MR arthrography of the shoulder were evaluated. 37 patients were examined before and after intraarticular administration of a 2-mmolar solution of Gd-DTPA. MR arthrography was performed if there was no joint effusion and/or an uncertain finding concerning the rotator cuff or the capsulolabral complex on plain MR images. MR arthrography leads to a better demonstration of labrum pathology in 11/22 patients and to a superior delineation of the capsuloligamentous apparatus in 20/22 cases. In 9/15 patients with impingement lesions MR arthrography allowed a differentiation of severe tendinitis from partial and small full-thickness tears of the rotat…

Laser surface treatments for adhesion improvements of aluminium alloys structural joints

2007

Abstract Laser technology is proposed as a friendly alternative treatment to chemicals involved in conventional prebonding adherend treatments. Aluminium alloy 2024 substrates were laser treated with different beam diameters and energy densities, and bonded using a structural epoxy adhesive. The influence of irradiation conditions on adherends morphology and adhesive joints’ fracture energy was investigated. On the basis of different morphologies observed, an explanation of the effect of the surface treatment upon joint mechanical behaviour is attempted.

MRT des Kniegelenkes: Fehleranalyse bezüglich der Meniskus- und Kreuzbanddiagnostik an einem arthroskopisch kontrollierten Patientenkollektiv

1998

PURPOSE To categorise discrepancies in findings of the menisci and anterior cruciate ligament (ACL) between arthroscopy and MRI. MATERIALS AND METHODS The MRIs of 236 patients were retrospectively analysed by an experienced radiologist without knowledge of clinical and/or operative findings. Discrepancies in arthroscopic findings were reevaluated together with the arthroscopist to determine their cause of error. RESULTS The diagnostic accuracies for injuries of the medial and lateral meniscus and the ACL were 92.4%, 92.4%, and 94.1%, respectively. For the menisci, causes for discrepancies in findings (n = 31) were: overinterpretation of central signal intensities with contact to the menisca…

What Can Plans Do for Legal Theory?

2012

In his book, Legality (2011), Scott Shapiro puts forward what he claims to be "a new, and hopefully better" (better, namely, than the ones given so far) answer to "the overarching question of ‘What is law?’ - The central claim of this new account - the "Planning Thesis" - is that "legal activity is a form of social planning" -. "Legal institutions plan for the communities over which they claim authority, both by telling members what they may or may not do, and by identifying those who are entitled to affect what others may or may not do. Following this claim, legal rules are themselves generalized plans, or planlike norms, issued by those who are authorized to plan for others. And adjudicat…

The synovial joints of the human foot.

2007

The human foot is considered an organ with an assortment of tissues with different morphological characteristics and well defined limits, but effectively has a simple functionality when static that becomes extremely complex when in movement. Its complex structure, comprised of an elastic and resistant skin covering a bone framework, joints, muscles, tendons, veins and nerves, can be compared to an efficient mechanical assembly. After a long and extraordinary evolutive journey, the human foot has undergone numerous changes to perfect its function; it has lost most of its grabbing function whilst gaining new characteristics that have ultimately allowed the modern man to stand upright. The com…
