Hybridising Signaling Principle And Nielsen’s Design Guidelines In A Mobile Application

Learning via mobile phone is very common nowadays, whether at the primary or tertiary stage. The use of mobile phones is causing growing concern among the general public. Improving online education, primarily via this device, is also one of the government’s most pressing needs. Most current research on mobile learning applications pays little attention to multimedia principles, especially the Signalling principle, to improve user interaction. As a result, this project is undertaken to suggest better and more efficient mobile learning applications. The model is developed in collaboration with various stakeholders, including content experts, HCI experts, actual users, and a thorough literature review. Creating these mobile learning design guidelines is anticipated to lead to a more efficient and successful mobile learning style. According to the results of the experiments, implementing the hybridised guidelines resulted in a significant increase in Asmaul Husna Islamic knowledge among university students.

Deposits of the hydrocarbon raw materials of the Republic of Kazakhstan, where it is possible to introduce a microbiological method for stimulating the formation

The article is devoted to the analysis and systematization of data on hydrocarbon deposits in the Republic of Kazakhstan, highlighting those aspects that will allow the use of this method. The microbiological method of exposure refers to the chemical methods of the tertiary stage of development of oil reservoirs. It has already proven its effectiveness in highly depleted, waterflooded formations with irregular, diffuse oil saturation. Its main advantages are its relative cheapness, it does not require additional equipment during injecting of the microorganisms into the reservoir, and for their nutrition, as a rule, food industry waste is used, and its implementation cannot cause harmful effects on the environment. Also, a fairly extensive database was compiled, according to which various classifications of the republic’s deposits were created.

Parametric Review of Surfactant Flooding at Tertiary Stage to achieve the accuracy for proposing the Screening Criteria

Abstract:: A critical review of previous studies is presented based on the contextual research background of surfactant flooding in this study. The parameters focused to achieve the analysis include permeability, salinity, temperature, and vis-cosity from different surfactant flooding operations. The principal theme of this review is to provide the regression analy-sis technique that may adopt to analyze the collected data and conduct contextual research. The set of analytical discus-sion is accomplished by extracting and plotting the basic parameters against recovery at Original Oil in Place (OOIP) and tertiary stages. Further, the success rate of such studies is compared to the grounds of oil recovery efficiency at different stages. Moreover, the failure of the surfactant flooding project can also be ensured by the outcomes of this study. It is revealed from this study that the recovery efficiency of surfactant flooding can be obtained maximum at lower per-meability ranges, however, other parameters such as salinity and temperature may possess some influence on recovery. In fact the fluid viscosity of reservoir fluid is inversely rated to recovery. The salinity, temperature and viscosity ranges for efficient surfactant flooding ranges may drop within the range from 1400 to 132606 ppm, 25 to 126 °C, and 1.9 to 150 cP respectively.

Modelling of Tertiary Creep In Copper at 215 and 250°C

For a long time, only empirical models existed for creep curves in the tertiary stage. To understand the role of creep damage, including changes in the dislocation structure, cavitation and necking, basic models that do not involve adjustable parameters have however, recently been developed. These models were used to predict tertiary creep for copper at 75°C. In the present paper, these models are applied to creep tests at higher temperatures (215 and 250°C). These results demonstrate again that tertiary creep in copper is primarily controlled accelerated recovery of the dislocation structure and not by cavitation. The modelling results suggest that the role of cavitation is modest also in other creep exposed ductile alloys, which should be of importance to consider in the formulation of models for creep damage. Necking was only found to be of significance very close to rupture again in agreement with results at lower temperature.

Iot Based Health Care System for Predicting Cardiac Issues

According to the survey conducted by the WHO (World Health Organization), out of 56.9 million deaths, Ischemic heart disease and Heart stroke account for 15.2 million deaths of the total deaths in 2016. These are regarded, as the Non-Communicable Diseases (NCD) also known as chronic diseases, tend to affect a person for a long duration. Along with in most of the cases, it is hard to find the disease existence in its primary stage; we can find it only with the symptoms like stroke or heart attack. Due to the lack of these symptoms, healthcare awareness and the financial needs many people are losing their lives. It is a very long process and cost effective. Hence, we are proposing a model, which predicts these symptoms with the implementation of latest technological advances like IoT, machine learning and deep learning algorithms. The proposed methodology takes place in three stages. Primary stage consists of collecting the data through sensors attached to the patient. Secondary stage involves the transfer of data from the microcontroller to the application and converting the data to suitable form. Tertiary stage involves feature extraction of the data and classification of the data using the CNN algorithm. All the stages run dynamically and generate the results based on the data collected. These results are then analyzed to check if the patient has arrhythmias or normal.

Secondary Syphilis in Human Immunodeficiency Virus (HIV)-Infected Men Who Have Sex with Men (MSM): A Case Report

Background: Recently, the incidence of syphilis among men who have sex with men (MSM) has increased rapidly, especially among Human Immunodeficiency Virus (HIV)-infected MSM. Coinfection with these two organisms alter the symptoms and signs, progression of the disease, and the risk of progressing to the tertiary stage. Purpose: To report a case of secondary syphilis in HIV-infected MSM. Case: A 24-year-old male complaint of multiple redness macule for 1-month duration on his chest, back, groin, palm, and soles. The rash was neither painful nor pruritic. He also complains of hair loss resulting "moth eaten" alopecia. One month before, he had a painless ulcer on his genital, which resolved without treatment. His HIV infection was diagnosed two years earlier. He had been sexually active with multiple homosexual partners without using a condom since 2010. The Venereal Disease Research Laboratory test (VDRL) titer was 1/32, and Treponema pallidum haemagglutination assay (TPHA) was 1/20480. Initial treatment was a single dose of 2.4 million units of benzathine penicillin. Serologic examination was reevaluated on month 1, 3, 6, and 9 after therapy and declined in the third month. Discussion: For HIV-infected persons, the clinical manifestations of syphilis in most of the cases remain the same. However, the lesions are more aggressive, and coexistence of primary and secondary syphilis is more frequent. Serologic tests are accurate and reliable for the diagnosis and for following a patient’s response to treatment. Penicillin is effective but physical and serological follow up is needed. Conclusion: HIV-infected MSM have higher risk of syphilis. Staging is needed to determine the treatment. Serologic examination should be repeated and long enough to monitor the treatment success.

Identifying the Dependency Outline of Students’ Attendance in Tertiary Level using Markov Chain and Logistic Regression Model

The schooling of tertiary level is a source of culture for any nation and this issue has always been a major public concern. The success of this level depends on various issues that can influence the students to gather knowledge. Among them, class participation is vital for understanding the course contents. The education system of Bangladesh is almost sound and well-organized in all levels including tertiary stage. Even so sometimes, students are unwilling to attend in the classroom for a number of reasons. In this study, we measured how previous absence of a student impact on their further absence. Markov Chain is a mathematical tool that identified the chance of previous absence effect on the recent absent. In another methods, logistic regression showed the dependency of today’s absence on previous absence. In this work, we got, the previous day absence influenced the student to continue his/her absent on the current day. Therefore, students’ continuous class participation is important and any sorts of discontinuity makes a barrier to participate in the next class
