STUDY OF THE PROCESS OF CALLING GOD'S NAME FROM SCIENTIFIC GLASSES: ASPECTS OF DZIKRULLAH BY SCIENCE
Authors: Ibrahim Iskandar 
Published: February 2019

Purpose of the study:This study is an academic response to a long debate about the practice of zikrullah in the community in order to get answers scientifically.
Methodology:The author uses combined data in this study, qualitative data to find models of zikrullah and quantitative data through Electro Encephalo Graf to see the mechanisms and effects of zikrullah on the human brain.
Main Findings: The results of the study show that in zikrullah there are five main aspects, namely the aspect of breathing as a mechanism for gas exchange for metabolism in the body, the voiceless aspect as the process of presenting zikrullah energy which will be transmitted to the brain, aspects of hearing to accelerate the presence of alpha waves, aspects of remembering as mental processes affect the limbic system and the aspect of the body's pattern as a union of several energy points.
Applications of this study:Therefore, the authors conclude that this study is a new approach to seeing the process and expressing the significance of the zikrullah towards humans. The United Nations, especially WHO can use the results of this study to help humanity who needs a spiritual approach.
Novelty:Zikrullah has been practiced for more than a thousand years.The name of Allah has been mentioned throughout the history of mankind, but an explanation of the aspects of zikrullah according to the scientific perspective has not yet been completed. The attention of Islamic scientists who are still little about the mystical phenomenon causes an explanation of aspects of zikrullah according to the scientific perspective has not been completed.

Statistical Analysis Of A Class: Monte Carlo And Multiple Imputation Spreadsheet Methods For Estimation And Extrapolation
Authors: Fish Laurel J. , Halcoussis Dennis , Phillips G. Michael 
Published: February 2019

The Monte Carlo method and related multiple imputation methods are traditionally used in math, physics and science to estimate and analyze data and are now becoming standard tools in analyzing business and financial problems. However, few sources explain the application of the Monte Carlo method for individuals and business professionals who are not immersed in the realm of mathematics or science. This paper introduces these Monte Carlo methods for the non-mathematician and business student, providing examples where the Monte Carlo method is applied when only small samples are available. Statistical analysis and statistically sound extrapolation of sample characteristics to the larger class population can be facilitated by applying Monte Carlo methods and the related concept of multiple imputation, which is also explained. Appendices provide step-by-step instructions for using two popular spreadsheet add-ins to run Monte Carlo based analysis.
The Pedagogical And Institutional Impact Of Disruptive Innovations In Distance Business Education
Authors: Estelami Hooman 
Published: February 2019

The use of distance learning methods by universities has experienced significant growth over the past two decades. While this growth has been witnessed nearly equally across the various academic disciplines, it represents unique opportunities in business education. In this article we will profile how technological innovations in distance learning have historically caused disruptive changes in business education. The article then profiles three specific distance learning technologies that are emerging as revolutionary forces in changing business education. The impact of these technologies will be examined from both a pedagogical perspective and an institutional perspective. The influence of these educational technologies in addressing the unique needs of business students will also be discussed.
NPV Sensitivity Analysis: A Dynamic Excel Approach
Authors: Mangiero George A. , Kraten Michael 
Published: February 2019

Financial analysts generally create static formulas for the computation of NPV. When they do so, however, it is not readily apparent how sensitive the value of NPV is to changes in multiple interdependent and interrelated variables. It is the aim of this paper to analyze this variability by employing a dynamic, visually graphic presentation using Excel. Our approach illustrates how these variables, when increased or decreased to reflect the potential range of values in a business case, change the value of NPV, and hence affect the decision about whether to proceed with the project or to reject it. Furthermore, since sales revenue is one of the least certain elements in the business case, the presentation includes a probability estimate of whether NPV will be positive or negative, assuming that sales revenue is normally distributed with a known mean and standard deviation. The business case we have chosen for illustrative purposes is a global energy project. Nevertheless, financial analysts in any industry should be able to apply our dynamic spreadsheet approach to their projects as well.
Identifying Faculty Perceptions Of Awareness And Preparedness Relating To ADA Compliance At A Small, Private College In NE PA
Authors: Stevens Chad M. , Schneider Elizabeth , Bederman-Miller Patricia 
Published: February 2019

This paper explores post-secondary faculty perceptions of awareness and preparedness relating to Americans with Disabilities Act (ADA). Institutions of higher education are businesses. The largest threat to sustained viability for many businesses is litigation. Business-related litigation is often the result of non-employment discrimination or torts (violation of civil rights). Lack of knowledge (awareness and preparedness) is usually not a sufficient reason for defendants in business-related litigation. The number of college students reporting learning-related disabilities is growing. About 2.2 million students enrolled in higher education institutions have a documented disability (National Center for Education Statistics, 2016). Disability related litigation is a trending concern for institutions of higher education. Are post-secondary faculty ‘aware’ and ‘prepared’ to make the necessary accommodations for students with qualified learning disabilities in classrooms? ADA awareness is defined as cognizance relating to the Rehabilitation Act of 1973 and Americans with Disabilities Act of 1990. ADA preparedness is defined as readiness and ability to follow obligations relating to the Rehabilitation Act of 1973 and Americans with Disabilities Act of 1990. A moderate, positive correlation was discovered between the two variables, indicating the more awareness one has of ADA laws and requirements, the more prepared one is in dealing with accommodations for those with learning disabilities. Research indicates a need for updated and current training in the area of ADA awareness and preparedness of post-secondary faculty.
Exploring Innovative Pedagogy To Deliver Financial Education: A Peer-To-Peer Event With Students
Authors: Solis Oscar J. 
Published: February 2019

An innovative 2015 Financial Education Event utilized collaborative learning, peer-to-peer learning strategies, and multimedia to engage students and deliver financial content. Thirty-three students in a financial counseling class hosted the event for students from a personal finance course as well as the university community. For the event, the financial counseling class conducted research and created six financial infographics that were presented in an open-floor setting on six 70-inch monitors. The six financial topics included budgeting basics, conquering credit, how to be a smart shopper, how to manage student loan debt, kick-starting your first job, and life after college. The financial education event was an opportunity for students to interact and engage in financial dialogue in a fun, enthusiastic, and interactive environment. During this peer-to-peer educational event, students were able to explore, engage, and learn beyond the traditional classroom setting.

Wettability Alteration of Carbonate Reservoir Cores—Laboratory Evaluation Using Complementary Techniques
Authors: Khaleel Omar , Teklu Tadesse W. , Alameri Waleed , Abass Hazim , Kazemi Hossein 
Published: February 2019

Summary
The objective of this paper was to assess the applicability of relatively low-salinity brine and different surfactants for enhanced oil recovery (EOR) in carbonate reservoirs in the Middle East. Phase behavior, interfacial tension (IFT), contact angle, spontaneous imbibition, and ζ-potential experiments were performed.
The experimental work flow included a phase-behavior study followed by IFT, contact-angle measurements, spontaneous-imbibition measurements, and ζ-potential measurements at varying salinities and surfactant concentrations.
Contact-angle-measurement results indicated that surfactant solutions, in addition to lowering IFT, tend to change the core wettability from oil-wet or neutral-wet to more water-wet. Furthermore, the best results were achieved by adding an anionic surfactant. Moreover, spontaneous imbibition and ζ-potential measurements provided additional supporting data that diluted seawater (DSW), in a dilute anionic or nonionic surfactant solution, alters the wettability of carbonates to a favorable wetting state for improving oil recovery.
This research presents a set of diverse experimental data that confirms adding low concentrations of anionic and nonionic surfactants to DSW improves oil recovery from carbonate reservoirs.
Opportunities for selective reporting of harms in randomized clinical trials: Selection criteria for nonsystematic adverse events
Authors: Mayo-Wilson Evan , Fusco Nicole , Hong Hwanhee , Li Tianjing , Canner Joseph K. , Dickersin Kay 
Published: February 2019

Abstract
Background: Adverse events (AEs) in randomized clinical trials may be reported in multiple sources. Different methods for reporting adverse events across trials, or across sources for a single trial, may produce inconsistent and confusing information about the adverse events associated with interventions
Methods: We sought to compare the methods authors use to decide which AEs to include in a particular source (i.e., “selection criteria”) and to determine how selection criteria could impact the AEs reported.
We compared sources (e.g., journal articles, clinical study reports [CSRs]) of trials for two drug-indications: gabapentin for neuropathic pain and quetiapine for bipolar depression. We identified selection criteria and assessed how criteria affected AE reporting.
Results: We identified 21 gabapentin trials and 7 quetiapine trials. All CSRs (6 gabapentin, 2 quetiapine) reported all AEs without applying selection criteria; by comparison, no other source reported all AEs, and 15/68 (22%) gabapentin sources and 19/48 (40%) quetiapine sources reported using selection criteria. Selection criteria greatly affected the number of AEs that would be reported. For example, 67/316 (21%) AEs in one quetiapine trial met the criterion “occurring in ≥2% of participants in any treatment group,” while only 5/316 (2%) AEs met the criterion, “occurring in ≥10% of quetiapine-treated patients and twice as frequent in the quetiapine group as the placebo group.”
Conclusions: Selection criteria for reporting AEs vary across trials and across sources for individual trials. If investigators do not pre-specify selection criteria, they might “cherry-pick” AEs based on study results. Even if investigators pre-specify selection criteria, selective reporting of AEs will produce biased meta-analyses and clinical practice guidelines. Data about all AEs identified in clinical trials should be publicly available; however, sharing data will not solve all the problems we identified in this study.

Authors: Frühwald Tobias , Gärtner Ulrich , Stöckmann Nils , Marxsen Jan-Henning ,   Carolin Gramsch4, Roessler Florian Carolus 
Published: February 2019

Abstract

Background: Optimizing thrombolytic therapy is vital for improving stroke outcomes. We aimed to evaluate the efficacy of tenecteplase (TNK) compared to the current gold standard rt-PA (alteplase), with and without additional ultrasound treatment.
Methods: In vitro clots that are similar to ex vivo clots concerning their histological condition and their durability were generated from whole blood. For five treatment groups we compared relative clot weight loss (each n=60) and fibrin fiber density in transmission electron microscopy (TEM) (each n=5). The control group (A) was treated only with plasma. Two groups were designated for each rt-PA (B+C) and TNK (D+E). Groups C and E were additionally treated with ultrasound. Dosages were 50µg/ml for rt-PA and 30µg/ml for TNK. Results were evaluated by using analyses of variance (ANOVA) and post-hoc t-tests.
Results: Weight loss was increased significantly for all groups compared to the control group. Both TNK groups showed significantly increased weight loss compared to their counterpart rt-PA group (p≤0.001). For TEM only group D showed significantly decreased fibrin fiber density (p<0.05) compared to both rt-PA groups. Ultrasound did not significantly increase dissolution of clots with either method (best p=0.16).
Conclusions: Tenecteplase dissolved clots more effectively than rt-PA with and without ultrasound. A higher sample size could provide more convincing results for TEM.
Keywords: Stroke, thrombolysis, tenecteplase, ultrasound, transmission electron microscopy.
Anti-α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor GluR2 encephalitis in a myasthenia gravis patient with complete thymectomy: a case report
Authors: Luo Qingyang , Wu Xianghong , Huang Wen 
Published: February 2019

Abstract
Background: Autoimmune encephalitis (AE) is a newly recognized autoimmune disorders in which the targets are proteins or receptors involved in synaptic transmission and neuronal excitability. α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) is a subtype of glutamate receptor that mediates most of the fast excitatory neurotransmission in the brain.
Case presentation: A 50-year-old woman presented with subacute onset of memory loss and behavioral changes. High levels of serum (1:1000) and CSF (1:32) antibodies against the AMPAR GluR2 were detected. A wide range of abnormalities in 6-8 Hz low to middle slow waves was found by electroencephalographs, and high-intensity signals on fluid-attenuated inversion recovery in both the medial temporal lobe and hippocampus were identified on brain magnetic resonance images. This patient presented with myasthenia gravis and type B2 thymoma (World Health Organization Thymoma Classification) at age 48. This case was unique in that the patient initiated with the symptom of myasthenia gravis and thymoma two years prior to encephalitis, and a complete thymectomy was performed before AE onset without recurrence of the thymoma when encephalitis occurred.
Conclusions: Thymoma was reported to be associated with paraneoplastic neurological disease. This is the first time a thymectomy has been applied in a myasthenia gravis patient with thymoma two years prior to the onset of anti-AMPAR2 encephalitis. This case highlights the complexity of autoimmune encephalitis associated with thymoma.
Keywords: Autoimmune encephalitis, α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor, thymoma, myasthenia gravis.
