An Investigation into the Distribution and Concentration of Drugs of Abuse within Different Body Compartments and Relationship with Toxicity
Abstract in English: 
ABSTRACT Femoral blood is preferable in post-mortem toxicological analysis but may not always be available. Alternative specimens such as cardiac blood, vitreous humour, stomach contents, bile, urine, hair, bone, liver and muscle may be used. However, only limited data are available for the interpretation of drug concentrations in these alternative specimens. The aim of the study was to investigate the distribution of drugs in different body compartments in relation to levels in femoral blood and their toxicity. All post-mortem specimens from 95 subjects were provided by Professor M Tsokos, Institute of Legal Medicine, Germany. Ethanol was measured by gas chromatography, whilst other drugs of abuse were initially screened for by immunoassays (in blood, hair and bone by Cozart drug immunoassay kit; urine by cloned enzyme donor immunoassay). A general drug screen and confirmation was performed on all specimens using gas chromatography/mass spectrometry and drug quantification was by high-pressure liquid chromatography-tandem mass spectrometry. Drug levels in femoral blood and median concentration ratios in relation to femoral blood (range) were as follows: ethanol 4-365mg/dL, median ratios for cardiac blood 1.9 (0.8:1-42.3:1), vitreous humour 1.6 (0.7:1-9.4:1), urine 6.5 (1.7:1-153:1) and bile 11.3 (1.0:1-34:1); for cocaine 5-2413ng/ml, median ratios for cardiac blood 1.2 (0.2:1-7.0:1), vitreous humour 1.4 (1.0:1-3.3:1), urine 4.9 (0.4:1->1000:1) and bile 7.0 (0.6:1-41.6:1); for methadone 7-1795 ng/ml, median ratios for cardiac blood 1.4 (0.6:1->3.9:1), vitreous humour 0.7 (0.04:1-0.99:1), urine 0.7 (0.3:1->3.9:1) and bile 2.9 (0.7:1->9.6:1); for morphine 7-1756 ng/ml, median ratios for cardiac blood 2.0 (0.9:1-11.5:1), vitreous humour 1.0 (0.4:1-18.5:1), urine 2.2 (0.1:1-56:1) and bile 24 (1.3:1 -> 195:1). Similarly, in liver and muscle for cocaine the median concentration ratio in ml/g was 0.2 (0.04:1-1.0:1) and 0.1 (0.1:1-2.5:1) respectively; for methadone 0.3 (0.2:1-<0.7:1) and 0.1 (0.05:1->0.7:1) respectively; and for morphine 0.6 (0.1:1- 1.6:1) and 0.3 (0.1:1-1.6:1) respectively. In the majority of cases there was a good correlation between femoral blood levels and the concentration in other body compartments. This study has added to our knowledge and understanding of the usefulness of using alternative post-mortem specimens to study the distribution of drugs of abuse in different body compartments and how the concentrations relate to femoral blood levels and toxicity

FEATURE SELECTION & EXTRACTION ALGORITHMS FOR BRAIN COMPUTER INTERFACE
Abstract in English: 
A brain-computer interface (BCI) is a direct communication pathway between a human brain and an external device. In other words, a BCI allows users to act on their environment by using only brain activity, without using peripheral nerves and muscles. In BCI there are many paradigms; one of them is P300 which occurs in response to a significant but low-probability event. BCI data is considered to be high in their dimensionalities which reduce the system performance. Feature selection is a dimensionality reduction technique. Feature selection techniques study how to select a subset of features that enhance the performance of the system. The reason behind using feature selection techniques include reducing dimensionality, removing irrelevant and redundant features, reducing the amount of data needed for learning, and improving algorithms’ predictive accuracy. In this thesis, three types of feature selection techniques are compared and applied. These types are filter, wrapper, and hybrid. Fisher score, Determination Coefficient (r2), Regularized Fisher Linear Discriminant (RFLD), and Bayesian Linear Discriminant Analysis (BLDA) were used as evaluation functions. Differential Evolution (DE) optimization technique was used as searching technique. Two datasets were used to evaluate the results. Filter types were the preferred to be selected as feature selection method for P300 based BCI, in particular r2. This is due to the good reduction in dimension 64.8% and low computational cost 6.75ms. The time required for training and testing the classifier was improved by 83.62%.

The Role of The English Language Supervisors in Enhancing The Teachers' Linguistic Competence and Practices as perceived by EFL Teachers in Yemeni Public Secondary Schools
Abstract in English: 
Abstract Al-Soufi, Najeeb Abdulwahid Mohammed. (2010). The Role of The English Language Supervisors in Enhancing The Teachers' Linguistic Competence and Practices as perceived by EFL Teachers in Yemeni Public Secondary Schools: Teachers' Perceptions. Master Thesis, Yarmouk University. (Supervisor: Prof. Fawwaz Al-Abed Al-Haq) Key Words: Yemeni, Role, supervisors, English language, EFL, teachers, practices, competence and linguistic. This study aimed at assessing teachers’ perceptions of EFL supervisors' role in enhancing teachers' linguistic competence and practices in Yemeni public secondary schools based on the perceptions of EFL teachers. The study also investigated the effect of the respondents’ gender and experience on their perceptions. This study attempted to answer the following questions: 1. What is the role of EFL supervisors in enhancing the teachers' linguistic competence and practices as perceived by EFL teachers in Yemeni public secondary schools? 2. To what extent are the EFL teachers' perceptions of the supervisors' roles in enhancing teachers' linguistic competence and practices in Yemeni public secondary schools affected by the teachers' gender and experience? 3. Is there any congruence between the teachers' perceptions concerning the supervisors' role and the supervisors' actual practices when they visit their teachers? 4. What do EFL supervisors and teachers suggest in order to improve EFL teachers' performance in Yemeni public secondary schools? The sample of the study consisted of all male and female EFL teachers of public secondary schools for the scholastic year 2008/2009 in Secretariat of the Capital Sana'a. The number of EFL teachers who responded to the questionnaire was 323 male and female teachers. The subjects of the study responded to a researcher’s designed questionnaire which consisted of 42 items distributed to seven supervisory domains. The same items of the questionnaire are reproduced as an observational checklist used by the researcher to record his observations of the supervisors' performances on visits to teachers, and there is an open-ended question for teachers and supervisors. In answering the questions of the study, the means, standard deviations, ANOVA and percentages of the responses were calculated and analyzed. Findings of the study indicated the following: 1. The EFL teachers ranked the role of the EFL supervisor as "middle" on the total domain which means that EFL supervisors did not follow satisfactory methods in their supervision. 2. There were differences within the teachers' perceptions due to gender in favor of the female teachers. 3. There were differences within the teachers’ perceptions due to experience in favor of teachers of ten years and more experience. 4. There was a high congruence between the viewpoint of teachers and the researcher's observational checklists in all domains except the training sessions domain where it was low. Based on the results of this study, the researcher suggests that there be an urgent need for policy-makers, researchers, supervisors and teachers to reframe their ideas about teaching in a way that serves the development of teaching at all levels. Finally, the researcher recommends that similar studies be conducted in other Yemeni cities.
