This paper addresses the problem of quantifying the mechanical contribution of rockbolts installed systematically around tunnels (regularly spaced around the tunnel) excavated in rock masses. Assuming that the mechanical contribution of grouted rockbolts is that of increasing internal pressure within a broken rock mass, a new procedure for computation of ground response curves for a circular tu...

A reaction system of Michaelis-Menten enzyme on single substrate can be characterized by the initial substrate concentration before enzyme action (S0), the maximal reaction rate (Vm) and Michaelis-Menten constant (Km), besides some other required parameters. The estimations of S0, Vm and Km can be used to measure enzyme substrates, enzyme activities, epitope or hapten (enzyme-immunoassay), irre...

Today the impact of green intellectual capital on organizational sustainability have to be studied because rising environmental concerns. There are three components (GIC) which include relational (GRC), human (GHC) and structural (GSC). This study fundamentally related GIC dimensions business sustainability. Data from 238 SMEs in Thailand were collected analyzed through PLS-PM method. Findings ...

Residue curve maps are a powerful tool for the preliminary design of Reactive Distillation (RD). In this study, residue curve maps of the n-butyl acetate synthesis reaction were calculated based on the Langmuir–Hinshelwood–Hougen–Watson kinetic and UNIQUAC models to calculate the physical properties of the system. The results showed that the unstable node branch emerged from the n-butyl ace...

Methods Fifteen patients with AIS, aged 10-18, with curves 10 – 45 degrees, braced or not, were randomized into Schroth, or standard care, groups. The six-month Schroth intervention consists of weekly one-hour long group exercise sessions, combined with a daily 45-minute long home program, consisting of 3-4 exercises prescribed using an algorithm. Compliance was monitored with a logbook. SRS-22...

OBJECTIVE As a health-related quality of life (HRQOL) measure, the LupusQoL is a reliable and valid measure for adults with systemic lupus erythematosus (SLE). This study evaluates the responsiveness and minimal important differences (MIDs) for the 8 LupusQoL domains. METHODS Patients experiencing a flare were recruited from 9 UK centers. At each of the 10 monthly visits, HRQOL (LupusQoL, Sho...

Blind source separation presents an interest for several applications fields. In this study, focus is on the blind separation of biomechanical signals namely ground reaction force signals. We showed recently in [1, 2], that ground reaction force signals are cyclostationary. Thus, the idea of this paper is to make use of the cyclostationary character of ground reaction force signals to separate ...

Impaired control of mediolateral body motion during walking is an important health concern. Developing treatments to improve mediolateral control is challenging, partly because the mechanisms by which muscles modulate mediolateral ground reaction force (and thereby modulate mediolateral acceleration of the body mass center) during unimpaired walking are poorly understood. To investigate this, w...
