Maria Sklodowska-Curie, Pierre Curie

On July 26, 1895, Pierre Curie and Maria Sklodowska were married. On June 23, 1903, Maria presented her doctoral dissertation “Investigation of radioactive substances” at the Sorbonne, which described the results of hard work in previous years, including the isolation of new elements - polonium and radium. In the same 1903, Marie and Pierre Curie were awarded the Nobel Prize in Physics “in recognition of the exceptional services they rendered to science through the joint research of radiation phenomena discovered by Professor Henri Becquerel”. She became the first female - laureate and remained the only one until 1935, when her daughter Irene was awarded the Nobel Prize. In 1911, Marie Curie received the Nobel Prize in Chemistry “for outstanding achievements in the development of chemistry: the discovery of the elements radium and polonium, the isolation of radium and the study of the nature and compounds of this remarkable element”. Marie Curie became the first and to date the only woman in the world -twice the Nobel Prize winner. After many years, the proposal of Marie and Pierre Curie on the use of radium in medicine has been implemented at the present time. Studied and proved its effectiveness in the treatment of bone metastases of prostate cancer. The merits of these scientists before the whole world can hardly be overestimated. Humanity gratefully keeps a good memory for great discoveries for the benefit of people.

Neuroimaging Studies

This short chapter first describes studies using PET scanning and fMRI imaging carried out by the author in collaboration with colleagues over the past 25 years. The main purpose of the chapter is to assess the extent to which current work on neuroimaging is compatible with the findings and ideas derived from the cognitive experiments described in previous chapters. The questions asked include: What are the neural correlates of deeper processing, and does the neuroimaging evidence illuminate the reasons for the strong relation between semantic processing and good memory? Is there evidence to support the proposal that retrieval processes recapitulate encoding processes? Is the similarity between perception and memory borne out at the neural level? How does novelty affect memory, and is there a conflict between the claims that both novel and familiar experiences are associated with good levels of recollection? What exactly are processing resources at the neural level? And, finally, how does the author’s emphasis on remembering as an activity square with the evidence from neuroimaging studies?

Applying the Tri-Guna Model to Screen for PTSD Susceptibility

The Indian subcontinent has a vast history of endeavouring to understand and interpret human psychology. How one may act in certain situations and why they behave a particular way are some of the many questions the tri-guna model hopes to answer. The model contains a unique framework which has the potential for application within the sphere of mental health. The model will be discussed from variables of wellbeing, specifically, cognition, social and emotion. Through discussion of the models unique qualitative approach to personality and wellbeing, data from existing literature in regards to wellbeing and PTSD will be compared to the model to identify correlation and consider practical application, such as a possible screening tool for individuals expected to face traumatic situations. This analysis has identified protective features of cognition (good memory, processing thoughts and tolerating stressors), social (positive social interactions and relationships) and emotional stability that correspond to descriptions of traits under sattva. Contrary presentations of the reviewed variables that may increase PTSD likelihood relate to both tamas and rajas descriptions respectively. Through the tri-guna model, we can produce a thorough picture as to what personality traits and wellbeing variables are associated with a person and in doing so, we can formally produce their guna composition. Once the dominating gunas are known, we can estimate their susceptibility to PTSD. The more variables of wellbeing in the tri-guna model that are assessed, then a more detailed composition can be produced. An avenue of screening could be a standardised PTSD tailored tri-guna questionnaire that would be based on the variables of cognition, emotion, motivation, social, physical, living conditions and behaviour. The use of multiple choice answers could be selected that resonate as sattvic, rajasic or tamasic. After identification of at risk individuals, the next phase would be intervention. This could be achieved through activities and recommendations that enhance wellbeing, emphasising sattvic qualities which has been explored in other literature.

A Comparative Analysis of Multiple Fractional Solutions of Generalized Couette Flow of Couple Stress Fluid in Channel

This study provides the exact solutions of couple stress fluid (CSF) in channel. The Couple stress fluid is bounded by two plates in which the lower plate is moving with constant velocity Uo and the upper plate is fixed. The influence of external pressure gradient is considered on the CSF fluid. To transform classical CSF model we have introduced three approaches of fractional derivatives, (a) Caputo (b) Caputo-Fabrizio (CF) and (c) Atangana–Baleanu (AB) fractional definitions. The exact solutions have been obtained using the Laplace and finite Fourier sine transforms jointly. Furthermore, the effect of different fractional derivatives is compared and the results are shown in graphs. Moreover, parameters which effect the CSF motion are discussed in the graph. The most important out come from the given study is the comparison of Caputo, Caputo-Fabrizio and Atangana-Baleanu fractional models with classical CSF model. From the comparison it can be noticed that Atangana-Baleanu fractional model discuss the dynamics of the couple stress fluid with good memory effect as compared to Caputo and Caputo-Fabrizio fractional operators. The CSF model can be reduced to Newtonian fluid as limiting case and also investigated solutions in the absence of external pressure. Finally, Skin friction are evaluated for lower and upper plates and presented the obtained results in tabular form.

MARTIAL ART AUGMENTED REALITY BOOK (ARBOOK) SEBAGAI MEDIA PEMBELAJARAN SENI BELADIRI NUSANTARA PENCAK SILAT

Pencak silat is one of the archipelago cultures that must be preserved. Many people want to learn silat. Fighters need a good memory in practicing, to remember every silat movement. This must be done repeatedly to understand. For independent study, the only media available are manual books and no teaching aids. This causes the fighter to experience difficulties. Based on these problems, a medium is needed as a prop that can help fighters remember silat movements. To solve this problem, this research will make a learning media using augmented reality-based silat movement guide book (ARBook). This learning media serves as a guide to basic silat movements in the form of Android-based 3D animation visualization, with the aim of being a martial arts props. This makes this method better than the conventional manual method. Based on the results of alpha testing using a black box. So from these data, it can be seen that the 3D AR pencak silat motion application runs and in accordance with the specified functionality are included in the feasible category. In Beta testing that uses the acceptance method, 86% of respondents agree that the AR 3D Silat Motion Application is very useful, then 87% of respondents agree that it is easy to use, then 84% of respondents agree that the animated content is presented, and 79% of respondents are interested in using the Motion Application AR 3D Silat. Suppose calculated to have an average value of 84%. So it can be concluded that the value of 84% is included in the "Very Appropriate" category. Broadly speaking, Alpha and Beta testing shows that this application is considered very feasible and usable.

ANALISIS USABILITAS WEBSITE SIAM UMRI MENGGUNAKAN METODE USABILITY TESTING

The thing that underlies the existence of a website is the development of information and communication technology. This study aims to measure the Usability level of the Student Academic Information System (SIAM) Website at Universitas Muhammadiyah Riau. Some problems encountered were that there was no reusability evaluation of the UMRI SIAM website, as well as complaints from UMRI students when accessing the website. The reusability problem in this study was resolved by conducting usability testing with five dimensions proposed by Nielsen (1993), namely learnability, efficiency, memorability, error & user satisfaction when accessing the SIAM UMRI website and using the thinking aloud method which required 3-5 respondents. The subjects studied were expert users (UMRI students) and novice users (non-UMRI students). Based on the results of the analysis on the learnability dimension, it is found that the respondents have the ability to learn a good website. In the efficiency dimension, the results of the increase in the speed of completing tasks by the respondents are obtained. Furthermore, in the memorability dimension, the results show that the respondents have good memory ability. In the error dimension, there are 38 problems when accessing the SIAM UMRI website, and in the satisfaction dimension, the results of respondents' satisfaction when accessing the SIAM UMRI website are obtained with a score of 70. In addition, in this study there are recommendations for improving the SIAM UMRI website.
