Recovery And Fatigue Behavior Of Forearm Muscles During A Repetitive Power Grip Gesture In Racing Motorcycle Riders, Michel Marina, Priscila Torrado, Raul Bescós

School of Health Professions

Despite a reduction in the maximal voluntary isometric contraction (MVCisom) observed systematically in intermittent fatigue protocols (IFP), decrements of the median frequency, assessed by surface electromyography (sEMG), has not been consistently verified. This study aimed to determine whether recovery periods of 60 s were too long to induce a reduction in the normalized median frequency (MFEMG) of the flexor digitorum superficialis and carpi radialis muscles. Twenty-one road racing motorcycle riders performed an IFP that simulated the posture and braking gesture on a motorcycle. The MVCisom was reduced by 53% (p < 0.001). A positive and significant relationship (p < 0.005) was found between MFEMG and duration of the fatiguing task when 5 s contractions at 30% MVCisom were interspersed by 5 s recovery in both muscles. In contrast, no relationship was found (p > 0.133) when 10 s contractions at 50% MVC were interspersed …

A Conceptual Framework For Phase-Dependent, Composite Flood Risk Index (Fri) Curves Based On The Relationship Between Temporal Probability Of Flood Occurring (Ph) And Flood Vulnerability Index (Fvi) Along With Maps Of Fvi Within The Amite River Basin Based On The August 2016 Flood., Austin S. Guerin Mr.

LSU Master's Theses

Efforts directed at determining community vulnerability to flooding are limited and only include economic (dollar damages) and public safety impacts and do not consider the phase dependency of the system, i.e., pre-, during- and post-storm, both critical shortcomings for more broadly assessing community risk and developing comprehensive plans and mitigation strategies. This thesis first develops a framework based on a Flood-Vulnerability Index (FVI) approach and then demonstrates its usefulness, at the census tract level of detail, for three parishes in the Greater Baton Rouge, LA area, based on the August 2016 flood. FVI’s indicators are multidimensional and phase dependent: “Pre-Flood” …

Gas Evolution Phenomenon Of Methane In Base Fluids Of Non-Aqueous Drilling Muds Under Controlled Depressurization, Damilola Ojedeji

LSU Master's Theses

As wells become more complex and drilling conditions to reach targets prove even more challenging, being able to detect influx event early and safely handle these influxes has become one of the most important focus areas for improvement in well control safety. The high solubility of formation gas in non-aqueous drilling fluids however makes kick detection and safe handling of kicks more complicated. Recent studies are beginning to incorporate desorption kinetics in well control models to simulate the transient multiphase flow phenomenon associated with gas kicks in non-aqueous drilling fluids to foster safe handling of kicks. However, there is currently …

A Study Of Methane-Liquid Absorption Characteristics For Gas Influx Management, Scott A. Perry

LSU Master's Theses

The study of absorption mass transfer kinetics in non-aqueous base fluids and the investigation of the parameters that influence this process is crucial in the application to gas influx management. While there have been a large number of studies investigating the interaction and solubility of methane in non-aqueous drilling fluids, relatively little attention has been placed on studying the mass transfer kinetics for different scenarios within the wellbore and riser. During the drilling process, there are multiple ways in which the formation gas can come into contact with the drilling fluid via a gas kick. Once the gas influx dissolves …

Confucian Leadership Democracy: A Roadmap, Yutang Jin

Comparative Philosophy

What kind of polity is justified by classic Confucian values? Adopting an interpretive approach, this paper explores the idea of leadership democracy being expressive of classic Confucian values by first introducing the models of leadership democracy associated with Weber and Schumpeter and second connecting Confucian elitist values to them. I argue that leadership democracy best realizes the Confucian emphasis on the people as the source of legitimacy and the ruler as the engine of good governance. The Confucian idea of people-rootedness is borne out by citizens behaving as democratic plebeians who are empowered to choose their leader but devoid of …

40 Sets Of Strong Ground Motion Records Convey All Design Response Spectrums Located In Tartous, Syria, Dr. Seraj Jdyd

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

Selecting seismic records in Global Standards is, until now, based on matching design response spectrum, where records should have seismological characteristics similar to the expected earthquake for the considered site (magnitude, distance, fault mechanism and soil conditions). Then it is necessary to scale these records to match the intensity of the earthquake expected for the site. Generally, scaling can be made by ground motions uniform scaling in time domain to best match (in average) the target spectrum within a period range of interest. Design ground motions are typically prescribed by smooth response spectra. But it is preferred to use a …
