Electrophysiological Grading of Carpal Tunnel Syndrome
ORIGINAL ARTICLE Electrophysiological Grading of Carpal Tunnel Syndrome MUHAMMAD WAZIR ALI KHAN ABSTRACT Background: Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy caused by a conduction block of distal median nerve at wrist. Women are affected more commonly than men. Clinical signs are quite helpful in diagnosis but electrophysiological tests yield accurate diagnosis and severity grading along with follow-up and management. Aim: To utilize nerve conduction studies (NCS) to diagnose carpal tunnel syndrome and further classify its severity according to the AAEM criteria. Methods: This descriptive study was conducted at the Department of Neurology, Sh. Zayed Medical College/Hospital, Rahim Yar Khan from June 2013 to Dec 2014. Overall, 90 patients and 180 hands were evaluated through nerve conduction studies. Patients with clinically high suspicion of CTS were included for NCS. Clinical grading was done using the AAEM criteria for CTS. Other variables like duration of symptoms, handedness, bilateral disease and gender were noted. Mean and median were calculated for age of the patients. Results: Ninety patients and 126 hands were identified with carpal tunnel syndrome. Most patients (80%) were females with age range from 19 to 75 years. More than one third had bilateral disease. Dominant hand was involved in majority of the patients. Most patients had (42.8%) severe CTS as per AAEM criteria. Also duration of symptoms directly correlated with severity of disease. Conclusion: Nerve conduction study is a valuable tool in accurate diagnosis and grading of carpal tunnel syndrome. Keywords: Phalen sign, Tinel Sign, electrophysiology, median nerve INTRODUCTION 4,5,6 electrophysiological findings, are quite valuable . -

South Palo Alto Tunnel with At-Grade Freight
RAIL FACT SHEETS South Palo Alto Tunnel with At-Grade Freight About the Tunnel with At-Grade Freight For the tunnel alternative, the railroad tracks will be lowered in a trench south of Oregon Expressway to approximately Loma Verde Avenue. The twin bore tunnel will begin near Loma Verde Avenue and extend to just south of Charleston Road. The railroad tracks will then be raised in trench to approximately Ferne Avenue. The new electrified southbound railroad tracks will be built at the same horizontal location as the existing railroad track, however, the northbound track will be moved to the east within the limits of the tunnel to accommodate the spacing required between the twin bores. The railroad tracks in the trench and tunnel will carry only passenger trains. The freight trains will remain at-grade. The roadways at Meadow Drive and Charleston Road remain at their existing grade and will have a similar configuration that exists today with the addition of Class II buffered bike lanes on Charleston Road. This will require expanding the width of the road to maintain bike lanes through the overpass of the railroad. By the numbers Neighborhood Considerations • Diameter of twin bores is 30 feet. • Alma Street will permanently be reduced to one lane • Railroad track is designed for 110 mph. in each direction from south of Oregon Expressway to Ventura Avenue and from Charleston Road to Ferne • Meadow Drive and Charleston Road are Avenue. designed for 25 mph. • The train tracks will be approximately 70 feet below the Proposed Ground Level View - Looking Southwest • Maximum grade on railroad is 2%. -
Green Terramesh Rock Fall Protection Bund
Double Twist Mesh Project: 112 Bridle Path Road Date: May 2016 Client: Private Residence, Heathcote Valley Designer: Engeo Consulting Ltd Contractor: Higgins Contractors Location: Christchurch Green Terramesh Rock Fall Protection Bund The 22 February 2010 Christchurch earthquake triggered numerous rock falls causing damage to homes built close to cliffs. Many of those that survived were red zoned by the Government due of the risk of further rock fall or cliff collapse. The area around Heathcote Valley and in particular Bridle Path road was identified as an area of high risk requiring some form of rock fall protection structure to be constructed in order to protect dwellings from rock fall in the event of any further earthquakes. Geofabrics offers a range of solutions that includes certified catch fences and Green Terramesh rockfall embankments. A rockfall embankment was the preferred solution for this site which has the potential to experience multiple rock fall events. The use of Green Site Preparation Terramesh allows the embankment slopes to be steepened and the footprint reduced to form a stable and robust bund having high energy absorption characteristics. The structure is typically filled with compacted granular material or engineered soil fill with horizontal soil reinforcement (geogrid or DT mesh) inclusions. The front face can either be vegetated or finished with a rock veneer. Rockfall embankments have undergone extensive full scale testing in Europe. Actual rock impacts in excess of 5000kJ into Green Terramesh rockfall embankments located in Northern Italy have been back-analysed and the design methodology verified using numerical modelling (FEM) techniques. This research has resulted in the development of design charts to provide designers with a Bund Design simplified design method based on rock penetration depth. -

Slope Stability
Slope stability Causes of instability Mechanics of slopes Analysis of translational slip Analysis of rotational slip Site investigation Remedial measures Soil or rock masses with sloping surfaces, either natural or constructed, are subject to forces associated with gravity and seepage which cause instability. Resistance to failure is derived mainly from a combination of slope geometry and the shear strength of the soil or rock itself. The different types of instability can be characterised by spatial considerations, particle size and speed of movement. One of the simplest methods of classification is that proposed by Varnes in 1978: I. Falls II. Topples III. Slides rotational and translational IV. Lateral spreads V. Flows in Bedrock and in Soils VI. Complex Falls In which the mass in motion travels most of the distance through the air. Falls include: free fall, movement by leaps and bounds, and rolling of fragments of bedrock or soil. Topples Toppling occurs as movement due to forces that cause an over-turning moment about a pivot point below the centre of gravity of the unit. If unchecked it will result in a fall or slide. The potential for toppling can be identified using the graphical construction on a stereonet. The stereonet allows the spatial distribution of discontinuities to be presented alongside the slope surface. On a stereoplot toppling is indicated by a concentration of poles "in front" of the slope's great circle and within ± 30º of the direction of true dip. Lateral Spreads Lateral spreads are disturbed lateral extension movements in a fractured mass. Two subgroups are identified: A. -
