Development of Electromyography Signal Signature for Forearm Muscle

AbstractElectromyography (EMG) measures muscle response or electrical activity in response to a nerve's stimulation of the muscle. EMG is generally acquired through surface and needle or wire electrodes. The needle or wire electrodes are usually used by clinicians in a clinical setting. This paper concentrates on surface electromyography (sEMG) signal that is acquired in a research laboratory since sEMG is increasingly being recognized as the gold standard for the analysis of muscle activation. The sEMG can utilized for establishing signal signature for forearm muscles that becomes an important input in development of rehabilitative devices. This paper discusses the establishment of sEMG signal signature of female and male subjects for forearm muscles such as extensor carpi radialis, flexor carpi radialis, palmaris longus and pronator teres based on movements such as wrist extension and flexion, hand open and close, and forearm supination and pronation. This was achieved through the use of Butterworth Bessel, Elliptic and Chebyshev filters. The sEMG signal signature could be useful in the development of rehabilitation device of upper extremities

Depression, Anxiety, Stress and Perceived Social Support Among Breast Cancer Survivors in Tertiary Hospital in Malaysia

The emotional distress and psychosocial factors are links to the worst quality of life among cancer patients as well as survivors. It gives a negative impact on the survivors and their families. The objective of the study was to determine the correlation of depression, anxiety, and stress with perceived social support among breast cancersurvivors. This is a baseline finding of an educational intervention study. A total of 131 female breast cancer survivors were recruited while they went for their appointment at the Oncology clinic in one of the Tertiary Hospital in Kuala Lumpur. Baseline data was collected using the Depression, Anxiety and Stress (DASS) and Multidimensional Scale of Perceived Social Support (MSPSS) questionnaires. Descriptive analysis andcorrelation tests were used to determine the strength of a linear relationship between depression, anxiety and stress with perceived social support. The descriptive analysis showed that breast cancer survivors had a higher prevalence of anxiety (30.5%) as compared to depression (14.5%) and stress (12.2%). Perceived social support was higher among family support (96.2%) as compared to significant others (84.7%) and friends (71.8%). There was a fair negative correlation between: (i) depression and family support (r = -0.372, p < 0.001), and (ii) stress and family support (r = -0.342, p < 0.001). Other domains had a poor correlation (r < 0.030). The finding showsthat social support from the family and significant others have a significant but fair inverse association with the emotional aspect (depression and stress) of breast cancer survivors.

Impacts of various high beam headlight intensities on driver visibility and road safety

Based on several studies, driving above certain speed at night while using low beam headlights has been found to result in insufficient visibility to respond to road hazards. Luckily, vehicle headlight technology has advanced so much and the system is commercially available in many parts of the world. However, the technical development for optimal photometric performance raises a few questions. The use of high beam headlight system creates a glare to drivers of oncoming and preceding vehicles (because of both oncoming headlights and preceding taillights), to the extent that it has become necessary to determine the need to put a limit on the luminous intensity of high-beam headlights. This study shall therefore summarize and investigate visual performance that allows for evaluation of the potential benefits of increased luminous intensity by considering glare rating related to safety. Two different car models; the Proton Prevé and the Perodua Myvi were used in the experiments. The results showed that the highest average illuminance [lux] for single vehicle was 17.5, 7.5, 5.0 and 1.0 for the distances of 30m, 60m, 120m and 150m. However, the average illuminance based on total number of vehicles was 1.0, 0.5, 0.0 and 0.0 at distances of 30m, 60m, 120m and 150m, which were considered below maximum recommended safety level (max. 9.0 – 11.0 lux). The current average vehicle high-beam headlight control was found at the level of acceptable glare control (glare to oncoming and preceding drivers) and below the maximum level of illuminance rate with the normal speed of 40 km/h

Electroencephalographic responses to neck cut and exsanguination in minimally anaesthetized goats

Conscious animals typically experience sensory (nociception) and emotional pain, whereas unconscious animals that were minimally anesthetized would experience minimal emotional pain. To determine whether ‘silencing’ the emotional component through a minimally anesthetized model would minimize stress response, and thus improve animal welfare, this study aimed at comparing changes in electroencephalographic (EEG) activities associated with possible noxious stimuli following neck-cut slaughter in conscious non-anesthetized versus minimally anaesthetized Boer cross-bred goats. Ten bucks were randomly assigned to two groups of five animals each, and subjected to neck-cut slaughter when fully conscious (HS) or under minimal anaesthesia (AS) and exsanguinated. The anaesthesia was induced with propofol (5 mg/kg) administered to effect by rapid injection into a cephalic vein and maintained with halothane in 100 % oxygen. Changes in the root mean square (RMS) for each of alpha, beta, delta and theta waves, median frequency (F50) and total power of the EEG (Ptot) were compared in each group before and after neck cut and between groups following treatments. Electroencephalographic parameters did not differ between goats that were fully conscious or slaughtered under minimal anaesthesia. These findings showed that the noxious stimuli from neck cut were present in both conscious and minimally anaesthetized goats. Most importantly, the presence of emotional pain and nociception did not affect the extent of electroencephalographic responses significantly compared with animals that were experiencing nociception only.Keywords: brain activity, propofol-halothane anaesthetic, noxious stimuli, slaughte

The role of exploratory data analysis (EDA) in electricity forecasting

Exploratory Data Analysis (EDA) is an approach introduced by Tukey.The aim is to obtain an in depth understanding of data using graphics.This contradicts the classical approach which uses statistical summaries such as mean and standard deviation among others.Skipping EDA in investigating data can jeopardise the validity and reliability of the results.In this study, we highlight the crucial role of EDA in electricity forecasting via line chart to understand the existence of the four-time series components i.e. trend, seasonal,irregular and cyclical.Daily electricity load for financial year 2002 to 2006 are used.The EDA showed irregular patterns identified in the line chart are not irregular components but moving seasonal components which require different techniques of forecasting

Changes in Blood Constituents of Rabbits Subjected to Transportation under Hot, Humid Tropical Conditions

Unlike Europe (particularly, Italy and Spain), where a number of studies have been conducted on the stressful effects of transport on rabbit welfare, few studies have been conducted on transportation of rabbits under hot, humid tropical conditions experienced in countries like Malaysia. We studied the effects of transportation in hot humid tropical conditions of Malaysia on physiometabolic changes in New Zealand white rabbits. Eighty experimental animals were divided into two groups of 40 bucks each and transported for either 3 or 1 h. Transportation caused a significant upsurge of aspartate aminotransferase, alanine aminotransferase and creatine kinase activities (p<0.001) though did not significantly affect lactate dehydrogenase (LDH) activity (p = 0.0706). Both transportation periods caused elevation in plasma glucose levels, lactic acidosis and dehydration as evidenced through elevated packed cell volume and plasma protein concentration. It was concluded that regardless of the duration, transport of rabbits under hot humid tropical conditions, resulted in heat distress since the rabbits showed hyperglycemia, hypercalcemia, lactacidemia, lymphocytopenia, dehydration and increase in blood enzyme activities
