Hyponatremia, osmotic demyelination syndrome, and the importance of the patient’s history

Central pontine myelinolysis (CPM), first described in 1959, is a symmetrical non-inflammatory demyelinating disease with loss of oligodendrocytes that occurs most often following a rapid correction of severe hyponatremia (i.e., <120 mmol/L). It presents as a biphasic disease with initial seizure or encephalopathy, followed by clinical improvement and subsequent rapid deterioration with bulbar dysfunction, oculomotor dysfunction, various degree of paresis, and even locked in syndrome. Its occurrence is rare (≈0.6% of severe hyponatremia), it is diagnosed clinically and confirmed with brain imaging, ideally with magnetic resonance image, and it is reversible in approximately half the patients. Lesions are classically identified in the pons but extra pontine lesions (in basal ganglia, cerebellar white matter, thalamus, and hippocampus) have also been identified. The most commonly accepted molecular mechanism involves brain cell volume regulation with a rapid shift of osmole following brain edema which establishes during the chronic hyponatremic phase. For these reasons, osmotic demyelination syndrome (ODS) is a better term. The most identified risk factor is severe hyponatremia, but other electrolyte abnormalities can contribute, in particular, if the patient is an alcoholic or malnourished. This diagnosis should also be suspected in post-op patients with nausea and headache non-responsive to antiemetic and analgesic drugs. An essential step is an appropriate medical history, a list of medications, physical examination, and basic initial lab tests with the goal of identifying possible easily reversible causes of hyponatremia. Correction of severe hyponatremia with neurological symptoms should be done using rapid boluses of hypertonic saline solution in rapid succession with goals of increasing serum sodium by 5-6 mEq/L in the first two hours, which should be stopped if the level has risen by 10 mEq/L in the first five hours, and with the overall correction goal not to exceed 15-20 mEq/L in 48 hrs. This method has been shown safe in all hospital settings studied. Serial measurements of electrolyte levels and neurological examinations are recommended, as are correction of all electrolyte abnormalities, in particular magnesium and potassium. Thiamine should be given to all patients with chronic alcohol use who present with hyponatremia and encephalopathy.
Of The Accounting Information System And Enterprise Resource Planning (ERP)

: The use of the Enterprise Resource Planning Systems showed a significant growth. This growth has led to the need to have an empirical evidence about the accounting benefits from using that systems. The existences of accounting research on ERPS has created an opportunity for further research on the Accounting Information Systems (AIS) quality and effectiveness in the decision-making process related to the level of the use of the ERPS. This research is using alternative methods of Partial Least Square (PLS). The result suggests that the manager’s perceptions of the AIS quality affect the effectiveness of the decision-making process. The breadth of the use of the ERPS can be a moderating factor in the relationship between manager's perception of the AIS quality and the effectiveness of the decision-making process. Finally, there was no difference between the perceptions of the different department managers regarding the AIS quality and the effectiveness of the decision-making process on the breadth of the use of the ERPS. So that, our society will get information and try to make the best treatment, for this fatal disease.
Pedagogical strategies and Motivation of Hospitality Management Learners in a Higher Education Institution in Botswana

The Botswana higher education system has been producing low-quality unemployable graduates and the low levels of learner motivation is believed to be a major factor. Premised on the Self-Determination Theory, the purpose of this study was to explore the nexus between pedagogical strategies and motivation of hospitality management learners in a selected higher education institution in Botswana. A descriptive survey design was adopted while the quantitative methodology was employed. Descriptive and inferential statistics such as the mean, standard deviation, correlation and regression, which were products of the Statistical Package for Social Sciences (SPSS) software, were used to analyse data that was collected from 128 respondents who were selected from a population of 189 learners using stratified random sampling. This study provided empirical evidence on the influence of pedagogical strategies on learner motivation and will provide instructors with knowledge of pedagogical approaches that either facilitate or impede learner motivation. The findings of the study revealed a significant relationship between pedagogical strategies and learner motivation. However, it was discovered that certain pedagogical strategies employed by the instructors had a negative effect on learner motivation namely low quality of academic advising, not affording learners enough opportunities to do presentations in class and failure to effectively inculcate collaborative skills among learners. It is recommended that learners should be afforded opportunities for collaborative learning to stimulate peer engagement which facilitate motivation. The institution should ensure that the curriculum incorporates contemporary issues that are relevant to the learners, industry and society as this will instil in the learners a reason to want to learn with the assurance of ready employment after graduation.
Optimization of passivation in AlGaN/GaN heterostructure microwave transistor fabrication by ICP CVD

We have studied the effect of silicon nitride (SiN) dielectric passivating film deposition by inductively coupled plasma chemical vapor deposition (ICP CVD) on the parameters of AlGaN/GaN heterostructure high electron mobility transistors (HEMT). Study of the parameters of the dielectric layers has allowed us to determine the effect of RF and ICP power and working gas flow ratio on film growth rate and structural perfection, and on the current vs voltage curves of the passivated HEMT. The deposition rate changes but slightly with an increase in RF power but increases with an increase in ICP power. Transistor slope declines considerably with an increase in RF power: it is the greatest at minimum power RF = 1 W. In the beginning of growth even at a low RF power (3 W) the transistor structure becomes completely inoperable. Dielectric deposition for HEMT passivation should be started at minimum RF power. We have developed an AlGaN/GaN microwave HEMT passivation process providing for conformal films and low closed transistor drain–source currents without compromise in open state transistor performance: within 15 and 100 mA, respectively, for a 1.25 and 5 mm common T-gate (Ug = –8 V and Ud-s = 50 V).
Effects of opinion statements on laypeople's acceptance of a climate engineering technology. Comparing the source credibility of researchers, politicians and a citizens' jury

To examine the influence of different actors’ fictitious statements about research and deployment of stratospheric aerosol injection (SAI), we conducted an online survey in Germany. Participants assess researchers and a citizens’ jury to be more credible than politicians. Credibility has a strong positive effect on SAI acceptance in both pro-SAI and contra-SAI conditions. Reading the statement against SAI-deployment led to significantly lower acceptance scores compared to reading the pro-statement. However, the difference between messages was unexpectedly small, indicating that the message content was not fully adopted while underlying traits and attitudes mainly shaped acceptance even despite, or because of, low levels of knowledge. Abstract
Enhanced thermal conductivity for poly(vinylidene fluoride) composites with nano-carbon fillers

Polymer composites with high thermal conductivity have recently attracted much attention, along with the rapid development of electronic devices toward higher speeds and performance. Here, we reported a facile method to prepare poly(vinylidene fluoride) (PVDF) composites with nano-carbon fillers including zero-dimensional superfullerene (SF), one-dimensional carbon nanotubes (CNT) and two-dimensional graphene sheets (GS) by simple solution blending and compression molding. The effects of these nano-carbon fillers on the thermal conductivity of PVDF composites were systematically investigated. It was found that PVDF composites exhibit a higher thermal conductivity than that of neat PVDF. Among them, the thermal conductivity of PVDF composites with 20 wt% two-dimensional GS reaches a maximum (2.06 W m−1 K−1), which is approximately 10-fold enhancement in comparison to that of the neat PVDF. Such highly thermal conductive PVDF composites may enable some prospective applications in advanced thermal management.
Psycholinguistic Markers of Autobiographical and Traumatic Memory

This study examines psycholinguistic structure of autobiographical and traumatic narratives representing positive emotional and stressful traumatic life events. The research applied the cross sectional, between subjects design utilizing the independent variables of external agent they, space and time and dependent variable of word number in traumatic narratives for multiple regression analysis. The approval letter to recruit the participants through SONA system in 2015– 2016 academic year was obtained from Institutional Review Board of Oklahoma State University (USA). 64 undergraduates of nonclinical setting, females (n=37), males (n=27), mean age was 19.43 (SD=1.37) were recruited. PTSD-8: A Short PTSD Inventory assesses PTSD, the Linguistic Inquiry and Word Count (LIWC) analyzes traumatic and autobiographical narratives in terms of linguistic units and psychological meaningful categories. The results indicate that there are significant differences between pronoun they as external agent of proposition and psychological categories of negative emotions and anxiety in traumatic and autobiographical narratives. The frequency of these categories is higher in traumatic narratives compared with autobiographical narratives. External agent they, category of time and space taken together significantly contribute to word number in traumatic narrative. There is a negative correlation between focus on the past and word count, and positive correlation between social category and word count in traumatic narrative in nonclinical sample. To sum up, propositional structure of traumatic memory of individuals without PTSD is represented by external agent and context (place and time) taken together. Considering time as a significant negative predictor of creating traumatic narrative, temporal processing without overestimation of time is an important factor of avoiding PTSD. The principal theoretical implication of this study is that traumatic memory might be examined through psycholinguistic markers represented by propositional structures and psychological meaningful categories of traumatic narratives in individuals from nonclinical and clinical settings.
Volatility analysis and volatility spillover across equity markets between India and Europe

This paper is a comparative study of volatility spillover effects in India and European indices. The analysis used various GARCH models, in order to measure conditional volatility (GARCH), asymmetric effect in the conditional volatility (T-GARCH), volatility persistence in conditional volatility (E-GARCH), impact of conditional volatility on conditional returns (M-GARCH) and volatility spillover (GARCH (1, 1), with exogenous variable, for the period 2005 to 2018. The major results, regarding volatility spillover, revealed that Indian stock market had exercised strong impact on selected European indices. Volatility spillover was found to be from Indian stock market to European indices and vice-versa. According to the T-GARCH model, there was significant asymmetric effect on the conditional volatility. The results of E-GARCH model established volatility persistence in conditional volatility.
Experiencing Students' Difficulties in Learning Abstract Algebra

This paper aims to reveal the difficulties as experienced by graduate students while learning abstract algebra at master's degree in mathematics education in the first month of their enrollment. For, I adopted a case study of five students, interviewed them with the help of interview guidelines and observed their behaviors in the classroom, and triangulated this information with researcher’s experiences to explore the difficulties in learning abstract algebra. I used inductive method to analyze the information and concluded that graduate students have experienced several difficulties in learning abstract algebra including the difficulties in conceptualizing algebraic facts, constructing examples and non-examples; and proving theorems. Finally, the study suggests that graduate teaching need to focus on conceptual and procedural understanding of students, and emphasizing to construct examples and non-example as much as possible to improve students learning.
Mining of missing ship trajectory pattern in automatic identification system

Background/Objectives : Ship trajectories in Vessel Traffic Service (VTS) system are generated by integrating the Automatic Identification System (AIS) or Radar system. However, the AIS system has missing data section caused by AIS device problems, radio jamming, and so on. These data have been confusing ship navigators and VTS operators. Methods/Statistical analysis : In order to extract missing AIS data, time intervals of sequent points from each ship trajectory are calculated. The section with missing AIS data is above a threshold time limit defined by characteristics. Using k-means algorithm, missing AIS data were clustered into several clusters stored by ship’s ID and sailing direction. Using association rule mining analysis, meaningful association pattern were calculated by missing AIS dataset. Findings : As a result of the association rule mining, we found several missing AIS situation patterns. In case of the west route, the probability of missing AIS situation is high when they enter the east and passenger routes. Also, the probability of missing AIS situation of passing the passenger route is high when that ship enter the LNG, east and west routes. Improvements/Applications : These results can be used to predict the probability of missing AIS data in VTS system.
A Study on the Effect of Seam, Color and Boundary Priors on Salient Region Detection

Being the best creation of almighty Allah, human beings have the ability to analyse a visual scenario. They not only see an image, but can judge the importance of different parts of a visual area. They can easily differentiate a running car from its background, can tell the color of different objects in an image and can focus attention to some important parts of a visible scene. The value of this visual power of human is easily understood if one thinks about these. Achieving this wonderful human quality using machine is one of the most precious goals of today’s scientific researches. With the continuous advancement of imaging technologies, more and more visual data are being collected all over the world. But, a major portion of these data are left unprocessed. Image processing is used to process these types of visual data. For all image processing techniques, the initial goal is to find some target region for extracting information from the image. Saliency detection is the technique of computationally finding important regions of an image. It is usually done using the contrast information present in an image. Seam map is the combination of cumulative summation of energy values from different directions. In this thesis, a combined method is proposed which uses seam importance map along with boundary aware color importance map. Color importance map is the weighted average of different color channels of Lab color space. Some intermediate combinations which are closer to the proposed optimized version but differ in the optimization technique are also presented in this thesis. Several standard benchmark datasets including the famous MSRA 10k and ECSSD datasets are used to evaluate performance of the suggested method. The proposed saliency model has been compared with several state of the art methods for each dataset. The qualitative and quantitative results from those comparisons make things easier to understand. Besides that, comparison with those state of the art techniques and precision recall curves and F-beta values found from the experiments on several datasets prove the superiority of the proposed method. This robust saliency model can improve almost all types of vision related applications including object detection, robotics, medical image analysis, content aware image resizing etc. In this research, the proposed architecture of saliency detection technique has been applied into a simple implementation of pedestrian detection. Its application has significantly improved the result of pedestrian detection in terms of performance and accuracy.
Salicylic acid improves tolerance against salt stress through boosting antioxidant defense system in black bean.

To evaluate the effect of salicylic acid (SA) on seed germination of black bean plant under saline conditions, seeds were primed with salicylic acid (0, 2, 10, and 20 mM) and germinated under salt stress (0, 50, and 100 mM NaCl). The measured parameters included the percentage and rate of seed germination, seedling length and dry weight, malondialdehyde and hydrogen peroxide levels, and activity of catalase, ascorbate peroxidase and guaiacol peroxidase in the seedlings. Results showed the values of germination indices decreased with increasing the level of salt stress. However, SA priming (10 mM) alleviated the harmful effects of salt stress in black bean. SA increased seed germination percentage by 72% and 45% at 50 and 100 mM NaCl respectively, compared to the control condition. Germination rate augmented by 33% (at 50 mM NaCl) and 60% (at 100 mM NaCl) by SA priming compared to the seeds exposed to salt stress alone. Seedlings dry weight (+ 51% at 50 mM and + 34% at 100 mM) and length (+ 57% at 50 mM and + 29% at 100 mM NaCl) were significantly higher by priming with 10 mM salicylic acid, compared to exclusively salt stress-treated seeds. SA priming increased antioxidant enzymes activities and decreased the levels of lipid peroxidation and hydrogen peroxide in salt stressed black bean seedlings. In conclusion, salicylic acid priming (particularly at 10 mM) enhances salt tolerance in black bean via lessening of oxidative stress.
Hypothetical Aspect of Crowdfunding as Alternate Finance for University Spinoffs and Quadruple Helix

In recent years, researchers have investigated a variety of approaches to funding University spinoff (USOs) companies but there is limited research on using crowdfunding as an alternative source of funding USOs and the linkage of that to the Quadruple Helix model of innovation. Our study reviewed the defining literature on current funding streams for USOs and explored crowdfunding as an alternative source because existing research suggests most startup companies struggle to raise fund from the banks and other traditional sources.
HELLENIC MEDITERRANEAN UNIVERSITY DEPARTMENT OF ELECTRICAL AND COMPUTER ENGINEERING

Cancer is one of the most common chronic diseases, and the second leading cause of death in the developed countries. During treatment patients face several side effects, which are painful both physically and emotionally. This results to the need of seeking psychological support and constant monitoring of their psychological and physical condition. Diagnosis, follow-up and treatment, consist a great interest to the research field. The rapid development of the technology has significantly improved the treatment of cancer as its goal is early diagnosis and finding the right treatment. That process depends mainly on the type and the stage of the cancer and on the continuous monitoring of the patient throughout recovery. As technology and medicine evolve at a rapid pace, the need for better quality of life is growing. In this context the “mobile health” field is being added. This term refers to the variety of applications, which have been implemented for smartphones or wearables that are powered by user data. Such systems are either used exclusively by the patient as a personal health record or as an interface between the patients and the medical staff. This process aims in a model that focuses on the patient and the way they handle their health status. In this thesis we will deal with the implementation of a questionnaire of the mobile application MyPal, with which the user will rate his/her emotional state and then this will be visualized. Finally, special emphasis has been placed on the interface of the application, as well as in the usability, as it targets at the elderly and mostly patients are unfamiliar with mobile technology.
The Relationship between Internet Addiction and Psychological Wellbeing among Addis Ababa University Main Campus Students

The internet, being an integral part of human life, is widely used by university students for different purposes including academic related works, networking, entertainment and staying up to date with latest information. Nevertheless, making use of the internet excessively can bring about negative consequences in the lives of students. The present study sought to determine the relationship between internet addiction and psychological wellbeing among main campus students at Addis Ababa University. Employing a cross sectional research design, quantitative data from 304 university students (male = 156, female = 148) with a mean age of 20.76 years (SD = 1.42) were collected using demographic questionnaire (6 items), Young’s Internet Addiction Test (20 items) and Ryff’s Psychological Wellbeing scale (18 items). Descriptive statistical methods including frequency, percentage, mean, standard deviation, Pearson product moment correlation and inferential statistical methods such as Independent Samples T test, One Way ANOVA, and multiple regression analysis were used to analyze the data. The study found that 28.2 % of the participants were found to be addicted to the internet. Students who use the internet for entertainment purpose are more prone to internet addiction compared to students who use the internet for academic purposes. A higher level of internet addiction was observed among students who used the internet for more than six hours per day compared to those who used the internet for two hours and below. Majority (90.1%) of the students’ psychological wellbeing status was found to be high. Compared to second year students, first and third year students had a relatively higher status of psychological wellbeing. Students who use the internet for entertainment purposes reported a lower status of psychological wellbeing compared to students who use the internet for academic purposes. Similarly, spending more than six hours online per day was also associated with lower status of psychological wellbeing. Bivariate correlation showed that internet addiction and psychological wellbeing had a significant and negative relationship. Furthermore, multiple regression analysis revealed that psychological wellbeing was significantly and negatively associated with internet addiction, after adjusting for potential confounding factors. Based on the findings, it is safe to conclude that internet addiction is a risk factor for lower psychological wellbeing.
