Using Twitter Sentiment Analysis to Analyze Self-Sentiment of the POTUS

This article provides a discussion of different tools that can be used to perform research on Twitter. The study then utilizes sentiment analysis to demonstrate self-sentiment of the POTUS and compare it with popular news sources. A comparison in 2 time periods and 4 months apart was made to determine if there is a change in the self-sentiment of the POTUS versus common news sources. To perform sentiment analysis, we utilize Python and the Vader and Pandas libraries, and statistical analysis was performed for each of the datasets. The first round of tests were based on a November dataset and revealed the means between the public, FOX, CNN and the President were not equal and that the POTUS had a higher self-sentiment than the sentiment of the news sources. The second round of tests were based on the following April data collection and revealed that the self-sentiment of the POTUS was not significantly different from the public or FOX. However, it was significantly different from CNN indicating a possible clash between the POTUS and CNN news.
A HIERARCHY OF NON-EQUILIBRIUM TWO-PHASE FLOW MODELS

We review and extend a hierarchy of relaxation models for two-phase flow. The models are derived from the non-equilibrium Baer–Nunziato model, which is endowed with relaxation source terms to drive it towards equilibrium. The source terms cause transfer of volume, heat, mass and momentum due to differences between the phases in pressure, temperature, chemical potential and velocity, respectively. In the context of two-phase flow models, the subcharacteristic condition implies that the sound speed of an equilibrium system can never exceed that of the relaxation system. Here, previous work by Flåtten and Lund [Math. Models Methods Appl. Sci., 21 (12), 2011, 2379–2407] and Lund [SIAM J. Appl. Math. 72, 2012, 1713–1741] is extended to encompass two-fluid models, i.e. models with separately governed velocities for the two phases. Each remaining model in the hierarchy is derived, and analytical expressions for the sound speeds are presented. Given only physically fundamental assumptions, the subcharacteristic condition is shown to be satisfied in the entire hierarchy, either in a weak or in a strong sense.
Delay of Gratificatio n Children

To function effectively, individuals must voluntarily postpone immediate gratification and persist in goal-directed behavior for the sake of later outcomes. The present research program analyzed the nature of this type of future-oriented self-control and the psychological processes that underlie it. Enduring individual differences in self-control were found as early as the preschool years. Those 4-year-old children who delayed gratification longer in certain laboratory situations developed into more cognitively and socially competent adolescents, achieving higher scholastic performance and coping better with frustration and stress. Experiments in the same research program also identified specific cognitive and attentional processes that allow effective self-regulation early in the course of development. The experimental results, in turn, specified the particular types of preschool delay situations diagnostic for predicting aspects of cognitive and social competence later in life.
Dye Sensitized Solar Cells Using Carbon Nanotubes and Natural Dye

Technology is advancing to use energy which can be renewed and at the same time creating minimum pollution. Solar radiation is a clean and abundant source of energy. A dye sensitized solar cell (DSSC) can be a low cost solution to the energy applications. Dye sensitized solar cells were created with different material like carbon nanotubes(CNT) and graphite as counter electrodes. Natural dye was prepared from extracted pomegranate. The electrical behaviour (i.e. I-V characteristics) of these cells had been checked for different climates. These devices were studied for I-V characteristics at different light radiations. Keywords— DSSC, counter electrode, carbon nanotubes, graphite, pomegranate
Adherence of North-African Pulmonologists to the 2017-Global Initiative for Chronic Obstructive Lung Disease (GOLD) Pharmacological Treatment Guidelines (PTGs) of Stable Chronic Obstructive Pulmonary Disease (COPD)

Background No previous study has investigated the adherence rate of North-African pulmonologists to the 2017-GOLD PTGs. Aims To investigate the adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs and to identify the barriers to their adherence. Methods This was a cohort study involving clinically stable COPD patients who presented to a pulmonology outpatient consultation. The patients were classified as having been appropriately and inappropriately (over- or undertreatment) treated for the GOLD group. Logistic regression was performed to determine the adherence barriers to the 2017-GOLD PTGs. Results A total of 296 patients were included (88.1% males, mean age: 68 ± 10 years; GOLD A (7.1%), B (36.1%), C (4.1%), and D (52.7%)). The pulmonologists' adherence rate to the 2017-GOLD PTGs was 29.7%. There was a significant statistical difference between the adherence rates among the four GOLD groups (A: 19.0%, B: 20.6%, C: 8.3%, and D: 39.1%; p = 0.001). Differences were statistically significant between the GOLD group D and groups B (p = 0.001). Differences were statistically significant between the GOLD group D and groups B (p = 0.001). Differences were statistically significant between the GOLD group D and groups B ( Conclusion The adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs is low. It seems that the patients' age, socioeconomic level, national health insurance coverage, and GOLD groups influenced their adherence.

Features of a Good Story for Non-Technical Adults to Learn Emerging Technologies

The need to learn emerging technologies such as artificial intelligence is increasingly important not only for technical people but also for non-technical people. Previous studies showed the effectiveness of a story-based teaching method for both technical and non-technical people who want to learn emerging technologies. However, the difference between the story-building methods for technical people and non-technical people is not revealed. The purpose of this research is to pro-pose perspectives that reveal the differences in the stories used for emerging technology education and identify the effective story features suited for non-technical adult learners by comparing the different story-building methods used for technical people and non-technical people. In this study, we classified the story types into two perspectives: "past to present" and "present to future" and compared the two story-building methods in these perspectives. The novelty of this research is that the proposal of perspectives that reveal the differences in the stories used for emerging technology education and that we have identified the features of one of the effective stories suited for non-technical adult learners. We al-so examined the possibility of leveraging such differences in solving the issues that a class of non-technical people called conversational programmers is facing.

Characterization of Mangifera indica linn (family: Anacardiaceae.) seed endosperm gum for potential application as pharmaceutical excipient

Natural products are increasingly used as excipients in formulation systems over the synthetics because of their comparative advantages. This study was aimed at the characterization of Mangifera indica seed gum (MisG) extracted from its endosperm using microwave-assisted technique. Physiochemical, pharmacognostic, microbial load were carried out using established methods and standard protocols. The yield of MisG was 15.63 ± 0.05% w/w. Physicochemical analysis revealed that MisG had particle size of 115.00 ± 0.12 μm, moisture content of 10.15 ± 0.11%, pH of 6.20 ±0.03, swelling index of 2.27 ± 0.09, water binding capacity 112.0 ± 0.1%, viscosity of 1.1 ± 0.2cP, flow rate of 3.01 ± 0.09 g/sec, bulk density of 0.51 ± 0.01 g/cm, tapped density of 0.63 ± 0.01 g/cm, Hausner’s ratio of 1.23±0.03, compressibility index of 19.10 ±0.03 and angle of repose of 29.35°. Microbial evaluation revealed the absence of objectionable microorganisms while the total aerobic microbial and yeast and mould counts were 1.20x10 and 11.50 x10 respectively. These values did not exceed the microbial limits specified by the United States Pharmacopoeia. These desirable physicochemical, pharmacognostical and microbial properties suggest that MisG could have good excipient potentials in pharmaceutical formulations.

Comparative Study of the Antibacterial Effect of Nano-Silver Irrigant, Sodium Hypochlorite and chlorhexidine against Enterococcus Faecalis Biofilm

This study aimed to compare the antimicrobial effect of Nano-Silver Irrigant, Sodium Hypochlorite and Chlorohexidine against Enterococcus Faecalis bifilm. 60 Sixty, recently extracted, sound maxillary anterior teeth with completely formed apices and straight roots were selected in this study. Canals were instrumented using the Protaper Next system (Dentsply Sirona) 1 mm shorter from the apical foramen up to size X5 ( size# 50/06). Sterility of the teeth after complete root canal cleaning and shaping were achieved by autoclaving for 15 min at 121oC with the teeth immersed in distilled water. Enterococcus Faecalis Biofilm was prepared by mixing 5 mL of the bacterial inoculum with sterilized BHI, then inoculated in teeth samples for 60 days. Teeth were then divided after the incubation period into three groups; 20 teeth each, and were treated by delivering the each of the tested irrigating solution using sterile plastic syringes. The first group was treated with Nano-Silver 0.02mol/L (2000ppm) while the second was treated using with Sodium Hypochlorite (NaOCl) 5.25% and the third was treated usinwith Chlorohexidine (CHX) 2.0%. Serial rinses ensured 5 minutes contact period between the aseptic solution and the bacteria. Sterile paper points size 50 were introduced into the canals and maintained for 3 min for sample collection, after which the paper points were placed in test tubes containing 2ml of sterile saline and several dilutions were prepared. 100 µL of each dilution was applied to the blood agar culture plates and incubated at 37oC for 24 hours. A classical bacterial counting technique was used for each group after the treatment application for the recovery of viable E. faecalis on agar plates The results showed that the NaOCl had the highest antibacterial activity with high statistically significant difference with the other groups followed by the chlorhexidine group which also show statistically significant difference than the other two groups, then came the nano silver irrigant group which showed the lowest antibacterial activity among all the groups with statistically significant difference with them.
A Systematic Review of Efficacy Outcomes Reported from Clinical Trials Evaluating Vaccine Candidates Targeting Plasmodium Falciparum

socioeconomic impact. Over the past fifteen years a renewed global effort targeting Plasmodium sp. has led to a 47% reduction in malaria mortality worldwide with a 54% reduction in Africa alone, where 90% of cases are reported [1]. Between 2000 and 2015 it is estimated that the use of insecticide-treated bed nets, artemisinin-based combination therapy and use of sulfadoxine-pyrimethamine prevented between 542-753 million cases of clinical malaria. The most effective treatment and vector control programmes yielding reductions in measures of clinical burden by upwards of 90% [2]. However, replicating equally impressive outcomes is unlikely given that cumulative reduction in incidence attributed to such programs is likely closer to 40% [1,2]. The success of these strategies has reignited interest towards pursuing global eradication and over the last decade many countries have made considerable gains in reducing disease burden while approaching malaria-free status [3]. Unfortunately, it is generally accepted that existing control and treatment strategies will be unable to impede transmission sufficiently to attain malaria-free status in areas where malaria incidence remains high [4]. Subsequently, as part of the revamped global campaign committed to malaria eradication, vaccine development has accelerated rapidly with the 2013 WHO Malaria Vaccine Technology Roadmap setting a long-term strategic goal of developing a vaccine that achieves a minimum efficacy capacity of 75% by 2030 [5]. In 2011, the RTS,S/AS01 vaccine candidate was the first to conclude phase III trials and has since received a ‘positive scientific opinion’ from the European Medicines Agency (EMA) with policy recommendations pending from the World Health Organization (WHO). Although recommendations will depend on multiple variables, overall vaccine efficacy remains central to conversations regarding cost-benefit of widespread distribution when considering vaccination campaigns.
Properties of polycrystalline NiMnGa – alloys for application as magneto-mechanic Actuator

Magnetic shape memory materials can deform by some percent via twin boundary motion under the influence of a magnetic field. This effect is well documented for single crystals of Ni-Mn-Ga alloys with compositions around Ni2MnGa. It is demonstrated that this effect can be achieved in textured polycrystalline samples as well, which can be produced much more efficient than single crystals. Directional solidified samples were subjected to thermal and thermo-mechanical treatment in order to adjust structure and microstructure. A shape change larger than 1% was achieved in a Ni50Mn29Ga21 alloy by applying a magnetic field at room temperature.
The opportunities and challenges of serious games for people with an intellectual disability

Serious Games (SG) are increasingly used to deliver education and training to support well-being, social skills, independent living and online safety. This presents opportunities and challenges for users, developers and educational providers to ensure their benefits are available to all. People with intellectual disability (ID) experience high levels of digital exclusion. This article reviews and synthesises the literature on the use of SG with people with ID. Recent work indicates the importance of the psycho-social profile of the game player, mechanics, and game context. We consider how these factors influence the inclusivity of SG and how they could be addressed. We demonstrate how a psychological perspective illuminates the impact of the user’s psychological profile on game use and effectiveness, and explore how culture, personalisation and learning analytics can increase inclusivity of SG. We conclude by identifying wider challenges such as the need for multi-disciplinary working and a more integrated, conceptual framework for games design which addresses diversity in learning needs.
QUALITY OF LIFE IN GLAUCOMA PATIENTS KVALITET ŽIVOTA KOD OBOLELIH OD GLAUKOMA

Glaucoma is a progressive neurodegenerative disease that can lead to irreversible blindness, if left untreated. There are different modalities in glaucoma treatment, but the most common include using local hypotensive eye drops. Due to the visual impairment or the use of glaucoma medication, people with glaucoma often report different difficulties in everyday life. Simple exams and assessments of clinical glaucoma parameters (like visual field) are not sufficient to describe patients’ problems and needs. Therefore, the investigation of their quality of life (QOL) is indispensable in management of glaucoma patients. Quality of life in people with glaucoma is usually decreased and typically physical, psychological and social aspects are affected. Quality of life is usually evaluated with the use of patient reported outcome measures (PRO) and the most used form of PRO is questionnaire. Recently, two of the glaucoma specific questionnaires Glaucoma Quality of life-15 and Glaucoma Symptom Scale – have been validated in the Serbian language and are available for use in glaucoma populations. The main goal of glaucoma management should be preserving patients’ vision while keeping and improving their quality of life, which is the reason why QOL assessments are of a great importance in glaucoma.
Journal of Technology Management for Growing Economies

The paper aims at examining the impact of various consumer and product characteristics on adoption of e-commerce among consumers in India. The study is based on primary data collected through survey of consumers residing in and around Delhi. A structured-non-disguised questionnaire has been employed for collecting the information from the respondents about their demographics, shopping orientations, security and privacy concerns, technological familiarity, past online shopping experiences and intentions to buy various types of products through internet in future. Past online shopping satisfaction, recreational shopping orientation, education and income emerge as significant factors affecting consumer past online purchases. In respect of future online shopping intentions, only three consumer related factors viz., past online shopping satisfaction, past online shopping frequency and education, are found as significant predictors. Amongst product characteristics, product expensiveness is found to be negatively related to consumer future online purchase intentions. While consumers appear quite willing to buy services online that are high in their intangible value proposition, they appear somewhat ambivalent in their intentions to buy online the 'frequently purchased products'. Some of the consumer and product characteristics do influence consumer adoption of e-commerce. Study findings entail interesting implications for the marketers. They need to give adequate attention to consumer and product characteristics while designing their e-marketing strategies. As compared to goods, the surveyed respondents have expressed greater willingness to buy services online in future. Services thus appear to be more promising product category for sale through internet channel in future.
Perspectives on therapeutic neutralizing antibodies against the Novel Coronavirus SARS-CoV-2

A newly identified novel coronavirus (SARS-CoV-2) is causing pneumonia-associated respiratory syndrome across the world. Epidemiology, genomics, and pathogenesis of the SARS-CoV-2 show high homology with that of SARS-CoV. Current efforts are focusing on development of specific antiviral drugs. Therapeutic neutralizing antibodies (NAbs) against SARS-CoV-2 will be greatly important therapeutic agents for the treatment of coronavirus disease 2019 (COVID-19). Herein, the host immune responses against SARS-CoV discussed in this review provide implications for developing NAbs and understanding clinical interventions against SARS-CoV-2. Further, we describe the benefits, challenges and considerations of NAbs against SARS-CoV-2. Although many challenges exist, NAbs still offer a therapeutic option to control the current pandemic and the possible re-emergence of the virus in the future, and their development therefore remains a high priority.
Effect of comorbidities on hematopoietic stem cell transplantation outcome in adult patients with different hematologic diseases: a single-center experience in Egypt

Background Hematopoietic stem cell transplantation (HSCT) is a procedure that can restore marrow function in patients who have had severe marrow injury. It is either autologous or allogeneic. It has become increasingly important to optimize pretransplant risk assessment to improve hematopoietic cell transplantation (HCT) decision making. Single-organ comorbidity involving the liver, lung, heart, or kidney before HCT has been traditionally found to cause organ toxicity after HCT. The HCT-comorbidity index (HCT-CI) has provided better prediction of HCT-related morbidity and mortality compared with other non-HCT-specific indexes. Aim The aim of this study was to investigate the impact of various pretransplant comorbidities on the outcome of patients who had undergone either allogeneic or autologous HSCT in relation to treatment-related mortality, disease-related mortality, and overall survival. Patients and methods A retrospective study was conducted at the Bone Marrow Transplantation Unit, Ain Shams University, on 119 patients who were transplanted either using autologous or allogeneic HSCT. All of them were older than 18 years and had different types of hematologic diseases. The most frequent hematologic disease was acute myeloid leukemia (34.4%), followed by multiple myeloma (17.6%), acute lymphoblastic leukemia (16.8%), and lymphoma (10.9%), whereas aplastic anemia, myelodysplastic syndrome, chronic myeloid leukemia, and biphenotypic leukemia collectively represented 20.1%. They were either incomplete or partial remission. They were categorized on the basis of the HCT-CI as follows: mild score (0), 43 (36.2%) patients; moderate score (1-2), 60 (50.4%) patients; and severe score (΃3), 16 (13.4%) patients. The study data were collected from medical notes, pathology reports, and laboratory data. Results There was a statistically significant relation between the HCT-CI and overall survival (P = 0.012), disease-free survival (P = 0.007), mortality (P = 0.047), and the incidence of graft failure (P = 0.034). Conclusion We concluded that the HCT-CI is a better predictor for detecting the influence of comorbidity in patients with hematologic disorders on mortality, overall survival, and disease-free survival after HCT.
