Tea is a drink that is very familiar in the world and is very common in everyday life. Tea is also the most consumed and favored beverage by the public after water. Besides being beneficial, tea also contains compounds that have a negative impact on the body, namely caffeine compounds. Caffeine is an alkaloid of the methylxanthine group which plays a role in increasing the work of psychomotor in the body, and side effects that can be caused are anxiety, irregular heartbeat, difficulty sleeping, tremors, diuresis and others. The purpose of this study was to determine the caffeine content in black tea powder circulating in the Old Deli market. This type of research is descriptive with a purposive sampling method. The analytical method used is qualitative with murexide and quantitative ultraviolet spectrophotometry with a wavelength of 267nm. The results of a qualitative analysis of all positive samples contained caffeine. The average quantitative yield of caffeine in brand A black tea powder was (4,82 ±0,0356)%, B brand black tea powder (4,89 ± 0,0173)% and C brand black tea powder (4,93 ± 0,0531)%. The validation test results obtained linearity r = 0,9984, LOD and LOQ is 0,8074 mcg/ml and 2,6914 mcg/ml ,% recovery = 100,07%, RSD = 0,33%. Based on the results of research conducted, it can be concluded that ultraviolet spectrophotometry can be used to determine caffeine levels in black tea powder.

ABSTRACT In March 2020, concurrently with the outbreak of COVID-19 in Iran, the rate of alcohol poisoning was unexpectedly increased in the country. This study has attempted to make an overall description and analysis of this phenomenon by collecting credible data from the field, news, and reports published by the emergency centers and the Iranian Ministry of Health. The investigations showed that in May 20, 2020, more than 6150 people have been affected by methanol poisoning from whom 804 deaths have been reported. A major cause of the increased rate of alcohol poisoning in this period was actually the illusion that alcohol could eliminate the Coronaviruses having entered the body. It is of utmost importance that all mass media try to dismiss the cultural, religious, and political considerations and prepare convincing programs to openly discuss the side-effects of forged alcohol consumption with the public, especially with the youth. It must be clearly specified that “consuming alcohol cannot help prevent COVID-19.”

[Rehearsing the World and the Self – Montaigne and Gombrowicz] The article discusses intertextual, intellectual and poetological relations between Michel de Montaigne’s Essais and Witold Gombrowicz’s autobiographical project. The author shows that the Polish writer was inspired by the French classic’s open poetics and his concept of processual and interactional subject. Gombrowicz was also interested in more specific matters present in Montaigne’s work: philosophical praise of the body, criticism of scholasticism, opposition of the private to the public.

<p><a>It has been a great challenge for scientists to develop an anti-covid drug/vaccine with fewer side effects, since the coronavirus began. Of course, the prescription of chiral drugs (chloroquine or hydroxychloroquine) has been proved wrong because these chiral drugs neither kill the virus nor eliminate it from the body, but block SARS-CoV-2 from binding to human cells. Another hurdle in front of the world, is not only the positive test of the patient recovered from coronavirus but also the second wave of Covid 19. Hence, the word demands such a drug or drug combination which not only prevents the entry of SARS-CoV-2 in the human cell but also eliminates it or its material from the body completely. The presented computational study explains (i) why the prescription of chiral drugs was not satisfactory (ii) what types of modification can make their prescription satisfactory (iii) the mechanism of action of chiral drugs (chloroquine and hydroxychloroquine) to block SARS-CoV-2 from binding to human cells, and (iv) the strength of mefloquine to eliminate SARS-CoV-2. As the main protease (M<b><sup>pro</sup></b>) of microbes is considered as an effective target for drug design and development, the binding affinities of mefloquine with the main proteases (M<sup>pros</sup>) of JC virus and SARS-CoV-2, were calculated, and then compared to know the eliminating strength of mefloquine against SARS-CoV-2. The main protease (M<sup>pro</sup>) of JC virus was taken because mefloquine has already shown a tremendous result of eliminating it from the body. The current study includes the docking results and literature data in support of the prescription of a combination of S-(+)-hydroxychloroquine and (+) mefloquine. Besides, the presented study also confirms that the prescription of only hydroxychloroquine would not be so effective as in combined form with mefloquine.</a></p>

For many patients, a cancer diagnosis is followed by chemotherapy treatment, which works by attacking cells that are growing and dividing throughout the body. Although cancer cells grow and divide more quickly than healthy cells, both are targets. The loss of healthy cells is associated with side effects, such as memory loss and altered response to a variety of food and drugs. In this pilot study, we use the “Survey of female cancer treatments, effects on memory and alcohol awareness” to explore trends in female experience and awareness of side effects associated with chemotherapy. We examined 79 female cancer patients, 46 Spanish-speaking women in Puerto Rico and 33 English-speaking women in the continental United States, and compared the rates of a reported memory loss or an altered ethanol response following chemotherapy, whether or not potential side effects were discussed with a medical professional, and whether they experienced changes in alcohol consumption after treatment. A majority of participants reported having experienced short-term memory loss postchemotherapy. Changes in response to alcohol and an altered sensitivity to alcohol were also reported by 25%–47% of the respondents. Additionally, more than half of all female cancer patients reported that they wished they would have received information on the side effects of chemotherapy and secondary medications prior to treatment. The survey results suggest that medical professionals are not adequately informing women of common, potentially harmful side effects of chemotherapy. Women do wish to be more educated about potential side effects related to memory and alcohol and be given the opportunity to discuss potential outcomes with a medical professional prior to treatment to reduce the negative impact of treatment-related side effects on posttreatment quality of life.

The terms habitus and field are useful heuristic devices for thinking about power relations in international studies. Habitus refers to a person’s taken-for-granted, unreflected—hence largely habitual—way of thinking and acting. The habitus is a “structuring structure” shaping understandings, attitudes, behavior, and the body. It is formed through the accumulated experience of people in different fields. Using fields to study the social world is to acknowledge that social life is highly differentiated. A field can be exceedingly varied in scope and scale. A family, a village, a market, an organization, or a profession may be conceptualized as a field provided it develops its own organizing logic around a stake at stake. Each field is marked by its own taken-for-granted understanding of the world, implicit and explicit rules of behavior, and valuation of what confers power onto someone: that is, what counts as “capital.” The analysis of power through the habitus/field makes it possible to transcend the distinctions between the material and the “ideational” as well as between the individual and the structural. Moreover, working with habitus/field in international studies problematizes the role played by central organizing divides, such as the inside/outside and the public/private; and can uncover politics not primarily structured by these divides. Developing research drawing on habitus/field in international studies will be worthwhile for international studies scholars wishing to raise and answer questions about symbolic power/violence.

Based on the studies of Don Ihde on the “embodiment relations” between the body and technological artifacts, Gretchen Schiller’s concept of “kinesfield,” and revisiting Merleau-Ponty’s (1945) concepts of “body schema” and “flesh of the world,” this chapter examines the forms of relation that are established in the bodily experience of mediadance, promoting new sensorial and perceptive experiences for dancers and for the public/participant/user, such as innovative forms of body re-presentations and new ways for the public to experience dance. Examples include intermedia performances that allow the performer to make changes to sound and light on the stage or in videos that, through cameras and software, translates movements into sound, light, or graphical patterns. Interactive user-computer software, like Wii and the Sony motion controller, allow the capture (by video) of the movement of the user transmitting it to a virtual body and environment. And dance telematics creates virtual encounters between remote dancers.

Cigarettes are packaged processed tobacco products, produced from the Nicotiana Tabacum, Nicotiana Rustica plants and other species or synthetics that contain nicotine with or without additives. Smoking is known to the public as one of the causes of death in the world that is quite large such as asthma, lung infections, oral cancer, throat cancer, lung cancer, heart attacks, strokes, dementia, erectile dysfunction (impotence), and so on. This research aims to build an application that can recognize cigarettes automatically and conceal pictures so that people especially minors are not affected by cigarettes. The application is built using the Region-based Convolutional Neural Network (R-CNN) method. The study uses images that have cigarette objects in them. The test is carried out to find out the application performance such as the level of application accuracy in recognizing cigarette objects. Based on the test results with a sample of 126 cigarette images, the application built is able to recognize cigarette objects by obtaining an accuracy value of 63%.

I propose a theoretical-practical approach to the presentation and representation of the female body in artistic creation. That is, the use of the body as a space at the limit, liminal, of danger and transgression, with the consequent potentially re-signifying effects of territory and common space through art. This narration is accompanied by the dissection of the creative process in phases and its final product, where I start from my own body, as testimony, meeting place, object and subject, studying its relationship with the context in an act of defiance to patriarchal authority. In this sense, we could relate it to the de-hierarchisation and proximity to others, in an unregulated but vital encounter of desiring, non-docile subjectivities, which eroticize politics with their irruption into the public sphere, with the intention of living, creating, loving, inventing another society, another perception of the world and other value systems.
