    Get PDF
    Central Neuropathic Pain (CNP) is a frequent chronic condition in people with spinal cord injury (SCI). In a previous study, we showed that using laboratory brain-computer interface (BCI) technology for neurofeedback training, it is possible to reduce pain in SCI people who suffered from CNP for many years. In this study, we show initial results from 12 people with SCI and CNP who practiced neurofeedback on their own using our portable BCI, consisting of a wearable EEG headset (Emotiv, EPOC, USA) and a computer tablet. Eight participants showed a positive initial response to neurofeedback and seven learned how to use portable BCI on their own at home. In this paper, we present a portable BCI and discuss the main challenges of training lay people, patients and their caregivers, to use a custom designed BCI application at home

    Cognitive Behavioral Therapy for Incest “Case Study”

    Get PDF
    The aim of the study was to apply the cognitive behavioral therapy to the incest case, to identify the characteristics of the victims of incest, and the characteristics of the perpetrator. There is no real percentage of prevalence for several reasons, including social stigma, fear of loss of breadwinner, family disintegration, and disbelief of the victim.... etc. The perpetrator is mostly a father or brother who may suffer from: psychological disorders, drug and alcohol abusers, sexual problems, organic deterioration of the brain cells or hardening of the cerebral arteries, or misinterpretation of stimuli issued by the victim, some think that he has the right to act as he pleases, and the act of abuse will not harm the victim.The victim is often a daughter or a sister in adolescence age, feelings of hatred, feelings of guilt, and problems with sex in adulthood are manifest. The extreme aversion of men leads to non-marriage, prostitution, multiple psychological and psychopathic crimes, depression and post-traumatic stress disorder which may lead to suicide, The victims in most cases are forced to silence the crime for several reasons including: fear of family disintegration, loss of the breadwinner, fear of loss of love and gifts from the offender, fear of the negative social outlook of the family ... etc. Keywords: Case Study, Incest, Victim, perpetrator, Cognitive Behavioral Therapy

    E-learning plays an important role in education as it supports online education via computer networks and provides educational services by utilising information technologies. We present a case study describing the development of an Arabic language elearning course in statistics. Discussed are issues concerning e-learning in Arab countries with special focus on problems of the application of e-learning in the Arab world and the difficulties concerning the design Arabic platforms such as language problems, cultural and technical problems, especially ArabTeX works difficulty with LaTeX format. Thus Wiki is offered as a solution to such problems. Wiki supports LaTeX and other statistical programs, for instance R, andWiki offers the solution to language problems. Details of this technology are discussed and a solution as to how this system can serve in building an Arab platform is presented.E-learning, MM*Stat, Wiki, ArabTeX, Statistical software

    The Impact of the Companions' Approach on Ensuring the Quality of Thought among Muslims: Musannaf Ibn Abi Shaybah as a Model

    Get PDF
    The study aims to explain the Companions' approach to achieving intellectual security and the quality of sound thought. Also, it clarifies the error of extremists and their violation of the Companions' approach. The study followed the inductive, deductive, and descriptive approaches to achieve the study objective. The study concluded that the Companions' approach is a true benchmark by which the moderation or deviation of thought is measured. Also, the greatest immunization of thought deviation is to adhere to the Book and the Sunnah according to the Companions' understanding. This study is distinguished from previous studies in that it collected the impact of the Companions from Musannaf Ibn Abi Shaybah in achieving intellectual security. It set standards for the quality of thought among the Companions to serve as a beacon for scholars and preachers in protecting Muslim societies from thought deviations and refuting misleading suspicions to preserve the integrity of future generations and their ideas

    Elizabethan Presentation of the Islamic Script: A Socio-cultural Understanding

    Get PDF
    The Arabic Qur’?n entered Europe through Spain with Muslim conquerors in the eighth century. Though the Elizabethan treaties about Islam introduced the Qur’?nic teachings, Prophet Muhammad’s mission was rejected, and he was announced a false prophet. In Elizabethan literature, this anti-Islamic information is intently expressed against the Prophet and the Qur’?n. Crimes and evil characteristics are imputed to the stereotypes of the Moors and Turks. These evil traits are referred to the Muslims’ culture as they are represented being imbedded in the Qur’?n. Some Elizabethan dramatists have developed their interest in the Qur’?nic theology. It has been depicted to the Elizabethan audience that Qur’?n justifies the Turkish imperialism. For Marlowe, smashing or burning copies of the Qur’?n is a symbol of personal revenge and attack on religion.

    Limiting key drilling parameters to control mud losses in Basra\u27s oil fields, Iraq

    Get PDF
    Wells in Basra\u27s oil fields are highly susceptible to lost circulation problems when drilling through the Dammam, Hartha, and Shuaiba formations. Drilling engineers are challenged to select the optimum value for key drilling parameters such as ECD, Yp, MW, WOB, ROP, and RPM to mitigate mud losses in these formations. Many of these drilling parameters are inter-related and the overall impact of changing key parameters require extensive drilling experience and study. A multi-regression analysis was performed on mud loss event data for more than 300 wells drilled in Basra\u27s oil fields. From this analysis, a model was developed to predict the total mud losses. Mud loss was found to be significantly affected by MW, ECD, and ROP. Models for ECD and ROP were also developed from the multi-regression analysis. In the same vein, proactive approaches are made prior entering the Dammam, Hartha, and Shuiaba formations to prevent or mitigate the occurrence of the lost circulation. Key drilling parameters are estimated to use during drilling through these formations. In case preventive measures didn\u27t work, corrective actions are determined for each type of the mud losses to provide effective remedies, minimize NPT, and reduce cost. This dissertation will contribute toward a better understanding of how the different factors could affect the lost circulation which is believed to have a significant impact on the mitigation mud losses. Therefore, optimized preventive and corrective solutions will be designed for combating lost circulation --Abstract, page iv

    A comprehensive study of lost circulation with application in the South Rumaila field, Iraq

    “Drilling mud losses and problems associated with lost circulation while drilling account for a major expense in drilling oil and gas wells. By industry estimates, more than 2 billion USD is spent annually to combat and mitigate this problem (Ali et al., 2015). The South Rumaila field in Iraq is one of the largest oilfields in the world. Wells drilled in this field are highly susceptible to lost circulation problems when drilling through the Dammam, Hartha and Shuaiba formations. Lost circulation events range from seepage losses to complete loss of the borehole and are a critical issue in field development. This thesis describes a study of the lost circulation events in more 50 wells drilled in the Rumaila field. Lost circulation events were extracted from daily drilling reports. Key drilling parameters (e.g. RPM, RPM, bit type) and mud properties (e.g. density, yield point, gel strength) at the time of each event were recorded along with the lost circulation remedies attempted, and the outcome of those remedies. These data were analyzed to determine ranges for the key drilling parameters and mud properties that have the greatest chance of mitigating lost circulation in each of the three formations. Practical field information from a range of sources were reviewed and summarized to develop an integrated methodology and flowchart for handling lost circulation events in the South Rumaila Field. Best field procedures for avoiding or minimizing lost circulation events in the South Rumaila field were identified and were provided as tabled procedures, or as additional data in the appendices of this thesis. This study provides a unique compilation of information regarding traditional approaches and the latest approaches of lost circulation control. The thesis attempts to provide useful guidelines or references for both situations”--Abstract, page iii

    Effect of Inherent Anisotropy on Shear Strength Following Crushing of Natural Aqaba Subgrade Sand

    Get PDF
    Inherent anisotropy affects the overall shear strength of sand deposits. Soil inherent anisotropy was evaluated for pre-crushed Aqaba subgrade sand by deposition of soil grains onto an inclined surface. Crushing of Aqaba sand was induced by one-dimensional compression. Sand characteristic properties (mineralogical properties, grain size and crushing resistance strength) were determined by standard laboratory testing. Particle breakage factors and inter-particle void ratio were calculated from the initial and final gradations of the soil samples. Moreover, shear strength components for sand specimens were resolved. Inspection of the residual shear strength parameters showed an increase, where the amount of particle crushing increased regardless the level of the normal stress being applied. Furthermore, examining the effect of inherent anisotropy showed that a considerable amount of the dilation occurs when the particles tend to lie orthogonal to the horizontal plane regardless the extent of breakage
