Published: February 2022

Denisova Cave in the Altai Mountains is a key site for investigation the ancient history of North and Central Asia and the processes of interaction between groups of hominins that have inhabited this territory over the past 300,000 years. This article presents the new results of the Early Upper Paleolithic archaeological materials investigation from Denisova Cave. In 2017–2019 in the South Chamber of the cave, Pleistocene deposits of layer 11 were excavated, which accumulated in the first half of MIS 3. The general paleogeographic estimation of natural complexes in the vicinity of the cave during the formation of layer 11 is based on the results of investigation a representative collection of large mammals and small vertebrates bone remains. These data evidence to the mosaic nature of landscapes characterized of the mountainous country, with steppe and rocky biotopes predominating. In the lithic industry from layer 11, primary flacking is characterized by parallel technology, aimed at obtaining elongated flakes, large blades and small bladelets. A radial technique was used to obtain short and shortened blanks. The toolkit contains expressive specimens of end-scrapers, burins, and retouched blades with a well-defined Upper Paleolithic morphology. At the same time, a significant share in this industry is made by the Middle Paleolithic component, represented by various types of sidescrapers, as well as denticulate, notched and spur-like tools. Along with the lithic industry, formal bone tools such as eyed needles, awls, points, and polishers were discovered. A representative series of various personal ornaments made of animal teeth and bones, mammoth ivory, gemstone, and other materials includes beads, pendants, tubular beads, rings and tiaras. The continuity of the technical and typological sequence in the development of the industries of the Denisova Cave suggests the formation of the Upper Paleolithic traditions on a local Middle Paleolithic basis. These materials are associated with the Ust-Karakol industrial variant identified in the Early Upper Paleolithic of Altai Mountains.

This article presents the characteristics and chronology of the archaeological complexes of Middle and Late stages of the Upper Paleolithic in Baikal-Yenisei Siberia. We analyzed the development of Paleolithic cultures against the background of paleoenvironmental changes in the Sartanian cryochron (MIS 2 – the beginning of MIS 1). As a result of research in recent decades, new data and results have been obtained for geological deposits, archaeological objects and complexes of this time; their features have been revealed. Databases that include data on geoarchaeological objects (about 60) and the results of radiocarbon dating (122 determinations) have been created. Based on the analysis of deposits and the database of radiocarbon dating, the age of four Sartanian subhorizons was determined: sr1 – ~28–22 ka cal BP, sr2 – ~22–19.5 ka cal BP, sr3 – ~19.5–14.7 ka cal BP, sr4 – ~14.7–11.7 ka cal BP. Each of these subhorizons differs in paleoclimatic settings. Two large seismic events (~23–22 ka cal BP and 12.8 ka cal BP) associated with the activity of Baikal rift and led to serious restructuring of natural situations were identified. Based on the stratigraphic position of cultural complexes and their radiocarbon dating, four cultural and chronological groups were identified and the presence of three breaks (hiatuses) not provided with archaeological materials in sr2, the second half of sr3 and sr4 (YD) was revealed. For each group, the specificity of cultural complexes was determined, expressed in topographic and planigraphic features, in the features of knapping technologies, composition and ratio of inventory groups. Apparently, these cultural breaks were provoked both by a change in paleoclimatic settings, primarily aridization, and by seismic events. We believe that this did not lead to the depopulation of the region, but rather contributed to changes in the hunter-gatherers' livelihood strategies that led to a change in their habitats. Perhaps there were also sociocultural reasons. The basic complexes of sr1 (Malta-Buret) are of western origin, in the materials of the second half of sr1 eastern elements are traced, and the sr3 complexes have wide analogues in the Sartanian cultures of the Yenisei valley and together with them form a single cultural area in this time. The genesis of the sr4 (BA) complexes is still debatable, although there is a certain continuity with the previous stage. They are also characterized by a clear cultural and territorial unity.

Published: February 2022

Introduction: Intrahepatic cholangiocarcinoma (ICC) is rare and often diagnosed in an advanced stage. Neoadjuvant therapy is not established and data on its value are in palliative intention. In the case of a recurrence patients often are offered systemic chemotherapy as the only treatment option. We report on a patient with advanced intrahepatic cholangiocarcinoma who underwent multimodal treatment leading to a long-term survival. Case report: A 61-year-old woman presented with an advanced intrahepatic cholangiocarcinoma of the right liver lobe without evidence of metastatic spread. She had already completed two cycles of chemotherapy of Cisplatin and Gemcitabine resulting in stable disease. An extended hemihepatectomy of the right lobe including segments I, IVa and partially IVb was performed. The TNM status (8th edition) was pT2b (3), pN0 (0/6), M0, V1, G2 and R0. Ten months later recurrence was diagnosed and treated with microwave ablation. Recurrence occurred again and the patient underwent repeated resection 22 months after primary resection. After detection of repeated recurrence once more, repeated resection was performed 46 months after initial resection. The patient is still alive and tumor-free 7 years after primary resection. Conclusion: Multimodal treatment including preoperative chemotherapy, complete resection and repeated resection of recurrence as well as microwave ablation led to long-term survival in a case of advanced intrahepatic cholangiocarcinoma. Close follow-ups were crucial to offer the best treatment options.

Published: February 2022

Landslides are natural disasters that have resulted in the loss of economies and lives over the years. The landslides caused by the 2005 Muzaffarabad earthquake heavily impacted the area, and slopes in the region have become unstable. This research was carried out to find out which areas, as in Muzaffarabad district, are sensitive to landslides and to define the relationship between landslides and geo-environmental factors using three tree-based classifiers, namely, Extreme Gradient Boosting (XGBoost), Random Forest (RF), and k-Nearest Neighbors (KNN). These machine learning models are innovative and can assess environmental problems and hazards for any given area on a regional scale. The research consists of three steps: Firstly, for training and validation, 94 historical landslides were randomly split into a proportion of 7/3. Secondly, topographical and geological data as well as satellite imagery were gathered, analyzed, and built into a spatial database using GIS Environment. Nine layers of landslide-conditioning factors were developed, including Aspect, Elevation, Slope, NDVI, Curvature, SPI, TWI, Lithology, and Landcover. Finally, the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC) value were used to estimate the model's efficiency. The area under the curve values for the RF, XGBoost, and KNN models are 0.895 (89.5%), 0.893 (89.3%), and 0.790 (79.0%), respectively. Based on the three machine learning techniques, the innovative outputs show that the performance of the Random Forest model has a maximum AUC value of 0.895, and it is more efficient than the other tree-based classifiers. Elevation and Slope were determined as the most important factors affecting landslides in this research area. The landslide susceptibility maps were classified into four classes: low, moderate, high, and very high susceptibility. The result maps are useful for future generalized construction operations, such as selecting and conserving new urban and infrastructural areas. Doi: 10.28991/CEJ-2022-08-02-02 Full Text: PDF

Published: February 2022

Covid-19 pandemic impacts many changes in daily life, either in health, social, economic, and psychological context. People will be most likely to change the way they live their life every day, including in eating and working. This research aims to describe empirically how was the eating pattern and eating behavior on adults who work from home (WFH) during Covid-19 pandemic. Instruments used in this research were The Eating Pattern Questionnaire and The Eating Behavior Questionnaire, adapted from The Adult Eating Behavior Questionnaire (He, Jinbo, et.al., 2019). Total of 338 respondents (age mean = 35,13 years old; 69.8% female) from various professional backgrounds across Indonesia had completed the questionnaires. Results based on descriptive statistical analysis implied most of respondents had experience changes in eating pattern while WFH, such as: more food consumption, increased snack time, less consumption of fruit and vegetables, and less physical exercise. Changes in eating behavior, namely: 1) enjoy meal time more; 2) more excited to try new variants of food; 3) feel more uncomfortable for delayed meal-time; 4) get hungry more easily; and 5) think more about food when not busy. This research sets the foundation for regulation or intervention strategy in healthy eating behavior as a notable indicator for either nutritional and mental health status.

Published: February 2022

A poluição hídrica é um problema nas bacias hidrográficas brasileiras e, embora o monitoramento seja fundamental, não é suficiente para a gestão de recursos hídricos. Dessa forma, o presente trabalho visou apresentar a modelagem de qualidade de água como ferramenta de apoio a decisão na gestão hídrica na bacia do Piabanha. Devido à urbanização na bacia, essa foi diagnosticada quanto as condições de esgotamento sanitário; e qualidade das águas do rio Piabanha, em função do índice IQAFAL. O rio foi modelado, através do QUAL-UFMG, para os regimes de vazões médias, QMLT, e de referência, Q95. Comparou-se os cenários a partir das concentrações e classes de enquadramento, por trechos do rio. Diagnosticou-se que, apesar da cidade de Petrópolis possuir os melhores índices esgotamento sanitário da bacia, é o principal responsável pela poluição do rio Piabanha. Através da modelagem, caracterizou-se trechos iniciais do rio como classes 3 e 4. Verificou-se ainda que a bacia do Piabanha vulnerável a cenários de escassez devido à necessidade de vazão para diluir os efluentes. Por fim, a modelagem de qualidade de água permitiu identificar, pontualmente, as regiões que mais impactam no rio, e se apresenta como uma importante ferramenta de apoio a decisão na gestão hídrica.

MODIFIED SLOW DIGESTION TECHNIQUE FOR THE ISOLATION OF PATIENT-DERIVED CELLS: AN IN VITRO MODEL FOR THE DESIGN OF BREAST CANCER-ASSOCIATED STROMA
Authors: Irakleidis Foivos , Masucci Michael , Sfakianakis Eleftherios , Tan Peng H , Welch Hazel
Published: February 2022

Objective: Highly prevalent cancer-associated fibroblasts (CAFs) are understood to play a key role in tumorigenesis. Understanding of CAFs and tumor-associated stroma is considered to be essential in novel cancer therapies. Patient-derived cells (PDCs) more closely resemble tumor microenvironment compared with commercial cell lines that are subjected to genetic and phenotypic changes. However, PDCs use can be limited by challenges in isolating high-yield viable cultures. Overcoming these challenges would benefit novel personalized cancer research. In this study, we aimed to investigate the effectiveness of modified tissue digestion processing techniques of isolation of PDCs. Methodology: PDCs were isolated from breast tissues collected from patients who had previously been diagnosed with breast cancer. Modification of slow and fast digestion processing techniques was used, followed by analysis for morphology and protein marker expression. Results: Isolated PDCs were presented with different morphologies and functions compared with breast cancer cell lines. Higher growth potential was observed with a combination of maintenance and filtered conditioned medium. High expression of Vimentin and morphological characteristics of spindle-shaped large cells confirmed the PDCs as fibroblasts. The modified slow digestion approach used in this study was successful in isolating fibroblasts from retrieved breast tissue. The fast digestion approach was not viable and was abandoned early due to poor production of cells. Conclusions: PDCs were isolated using a modified slow digestion approach. PDC cultures can more effectively represent breast cancer stroma and are becoming an essential platform for research as a personalized in vitro model for molecular breast cancer research. This study presents a highly successful method of isolating PDCs from breast cancer patients.
AN IN SÍLICO ANALYSIS DETECTED MEMBERS OF THE PLECKSTRIN HOMOLOGY-LIKE DOMAIN FAMILY B AS POTENTIAL PROGNOSTIC BIOMARKERS IN PATIENTS WITH BREAST CANCER
Authors: Nascimento Renan Gomes do
Published: February 2022

Objectives: Despite advances in the molecular classification of breast cancer, our understanding of the pathophysiology of the disease is still limited mainly due to the considerable intratumoral heterogeneity. Thus, hundreds of other candidates for biomarkers are being investigated and studied for possible implications for diagnosis, prognosis, and personalized therapy. In this context, members of the Pleckstrin homology-like domain family B (PHLDB), which is composed of three genes located on different chromosomes: PHLDB1 (11q23.3), PHLDB2 (3q13.2), and PHLDB3 (19q13.3), are under investigation by different research groups as potential biomarkers in different types of cancer. It has been reported that the altered expression of these genes is involved in the tumorigenic process. In this study, we sought to understand the prognostic and predictive value of genes from the PHLDB family as potential biomarkers in breast oncology. Conclusions: Our findings provide new insights into the potential role of PHLDB family members as clinical predictors in breast cancer. Unlike what has already been described in the literature, it appears that members of the PHLDB family are potential tumor suppressor genes in breast cancer. Further clinical and experimental studies are needed to better understand the relationship between the expression of the members of the PHLDB family and the tumorigenic process of the breast and its prognostic and predictive values in breast cancer.
A questão agrária e a (re) distribuição fundiária no Brasil: engendramento do modelo institucional de federalismo cooperativo ecológico?
Authors: Battisti Lucas Garcia , Camardelo Ana Maria Paim
Published: February 2022

A estrutura fundiária concentrada é uma das principais expressões da formação político-econômica brasileira, conformando, simultaneamente, a desigualdade social e a degradação ambiental, mesmo diante de políticas ambientais e de reforma agrária, instituídas de maneira compensatória. O objetivo desse trabalho é verificar se há uma continuidade histórica, expressa no sistema de competências da Reforma Agrária e do Federalismo Cooperativo Ecológico, que indique uma resposta uniforme a estas expressões da questão social. Foi empregada a revisão bibliográfica e a pesquisa documental, pautada pela teoria do conflito e pelo método analítico. Mesmo que a abertura a participação, institucionalizada pelas tendências descentralizadoras, represente pontos de convergência entre as políticas ambientais e de reforma agrária, não há integração e continuidade entre estas políticas. Pelo contrário, houve o congelamento da reforma agrária, ante a emergência dos novos direitos, especialmente os ambientais, o que diminui o alcance da resposta à crise ambiental e da questão agrária.
Photo- and mechanoluminescent properties of the SrAl2O4 : (Eu2+, Dy3+) phosphor and its use to visualize the dynamics of material deformations
Authors:   Institute of laser and information technologies – branch of the Federal Scientific Research Centre “Crystallography and Photonics”  of the Russian Academy of Sciences, Banishev A.F.
Published: February 2022

The work investigated the deformations of materials arising from the action of high-power laser pulses. Composite mechanoluminescent materials based on a polymer and a phosphor powder were used to visualize and record the dynamics of the development of deformations. Mechanoluminescent materials were applied to the surface of the materials under study. It is shown that the spatial distribution of the glow intensity of the mechanoluminescent layer and the rate of its change make it possible to judge the magnitude and rate of deformation of materials when they are exposed to laser pulses. The kinetics and photoluminescence spectrum of composite materials were studied under the combined action of short-wave and long-wave laser radiation. It is shown that the photoluminescence excited by a long-wavelength laser is associated with the activation of the populated levels of the traps.

Pacto entre caballeros: estética de la brevedad en Logan Pearsall Smith y Julio Torri
Authors: Insausti Gabriel
Published: February 2022

La obra de Logan Pearsall Smith (1865-1946) y la de Julio Torri (1889-1970) ofrecen numerosas concomitancias, que en parte se explican como una decantación por el simbolismo y un rechazo del naturalismo y el positivismo desde contextos diferentes. Partiendo una renovación de la prosa moderna de fuentes francesas y del poema en prosa, ambos desembocaron en una exigua obra aforística.

Trends in Telehealth Care for Diabetes During the COVID-19 Pandemic
Authors: Campion Francis , Duffy Lucie , Burgman Aaron , Rojas Ricardo , Sangaralingham Lindsey , Sylvester Peter
Published: February 2022

Importance:  This very large claims data analysis documents widespread adoption of telehealth use by patients with diabetes during the first year of the COVID-19 pandemic, giving us insight into the potential role of telehealth as we enter a stage of “new normal” of healthcare delivery in the U.S.
Objective: The COVID-19 Telehealth Impact Study was designed to describe the natural experiment of telehealth adoption during the pandemic.  This focused analysis can assist program development for care of large populations of patients with diabetes. 
Design, Setting, Participants: In March 2020, the MITRE Corporation and Mayo Clinic founded the COVID-19 Healthcare Coalition (C19HCC) and Telehealth Impact Study to respond to the pandemic. We report trends using a data set of over 2 billion healthcare claims covering over 50% of private insurance activity in the U.S. (January 2019-March 2021).
Main Outcomes and Measures: We compared rates of telehealth use in the one-year pre and one-year post onset of the COVID-19 pandemic among a population of 8,339,633 patients with diabetes.
Results: Compared to a baseline of very low telehealth use in 2019, there was rapid adoption of telehealth by patients with diabetes in Spring 2020.  27% of diabetics used telehealth in Q2 2020 and use rates declined in the ensuing months to approximately 13%.  Diabetics and their providers used telehealth to address a wide variety of health problems.  77% of telehealth visits addressed diabetes, 53% hypertension and over 40% of visits addressed mental and behavioral health diagnoses.  Audio-only (telephone visits) accounted for a substantial portion of telehealth encounters (10.0- 16.3%) and will be an important consideration for future telehealth planning.  Over the course of the first 12 months of the pandemic, 98% diabetics who used telehealth used 4 or fewer telehealth visit.
Conclusions and Relevance:
We believe that telehealth will quickly become a best practice for routine care of patients with diabetes and other chronic conditions.  Telehealth interactions 2-4 times per year supplemented with remote monitoring for glucose, blood pressure and weight have the potential to greatly enhance patient care. Further research will be needed to measure the telehealth impact on glycemic control, patient satisfaction and other outcomes.  We encourage CMS and other payers to embrace and promote use of telehealth based on this real-world experience of patients and providers during the pandemic.

Authors: Goel Varun , Gupta Savita , Gupta Vivek , Sahni Ajay Kumar
Published: February 2022

Background: The contamination of patients’ surroundings by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains understudied. Discordant findings of SARS-CoV-2 RNA in environmental samples were noted in many reports.
Aims and Objectives: The study assessed the extent and persistence of environmental surface contamination in real-world surfaces around COVID-19 patients.
Materials and Methods: We sampled the surroundings of two intensive care unit (ICU) and one ward that were occupied by laboratory-confirmed coronavirus disease 2019 (COVID-19) patients. Frequently touched environmental surfaces near patients were swabbed before and after daily environmental disinfection.
Results: Of 355 environmental samples, 6 (1.69%) were positive by real-time reverse-transcription polymerase chain reaction assay. Among those, 5 of 75 ICU samples (6.67%) and 1 of 75 ward environmental samples (1.33%) in the pre-fumigation areas occupied by COVID-19 positive patients were positive. No samples obtained within the first 2 h of fumigation and surface disinfection was found to be positive.
Conclusion: Surrounding environment of symptomatic COVID-19 patients can get contaminated and in cases of asymptomatic COVID-19 patients, contamination of their surroundings was an uncommon phenomenon. Strict contact barrier precaution, routine cleaning with disinfectants are mandatory hospital infection control practices in the management of patients infected with SARS-CoV-2.
A cat scratch disease case presenting with underarm painful lymphadenopathy
Authors: Yardimci Bulent
Published: February 2022

Cat Scratch Disease is an infectious disease that typically begins as a cutaneous lesion and causes proximal regional lymph nodes enlargement. In general, it is infected as a result of cat saliva and scratches. It rarely causes systemic manifestations. Since it may be observed worldwide, the differential diagnosis should be strictly introduced in case of local lymphadenopathies.
Involvement in Self employment among Returnee Migrants in Chitwan
Authors: Tiwari Pradip Raj
Published: February 2022

Motivated by emerging issues of migration in Nepal, particular to returnee migrants, this paper examines the situation of returnee migrants and their participation in self employment based on cross-sectional data from 243 returnee migrants in three VDCs of Chitwan. The result shows that age, education, country of returned and re-migration plan are the major determinants of participation in self employment among returnee migrants where adult returnee migrants were more likely to engage in self employed compare to youth. The result also shows that the Gulf and Malaysian returnees who are not eager to migration again are more likely (odd ratio=2.645, p<0.01) to participate in self employment activities than those who returned from India. But, returnees from developed countries have no significant relation on participation in self employment. This study sheds light on a very important policy issue for Nepal particular to the economic development and participation in entrepreneurs’ activities of returnee migrants depends on country of return and their earning during the migration period. Thus, policies focusing on those returnee migrants are paramount for the development entrepreneur’s activities in the study area.
Case study on the size of the particle for transmission probability to take place through the barrier
Authors: Neupane Rajendra
Published: February 2022

Diffraction phenomenon occurs when the wavelength of the wave is comparable to the size of the obstacle. Tunneling through a barrier occurs when the particle size is comparable to the width of the barrier. The Transmission probability versus potential energy curve is hyperbolic in nature. This main aim of this article is to show that there is no probability of penetrating the particle through the barrier if barrier width is extremely larger and extremely smaller than the particle size. The condition for tunneling is similar to the necessary and sufficient condition for diffraction to occur. The various examples presented here shows that the penetration of the particle through the barrier is only possible when the size of the particle is comparable to the size of the barrier height. This article shows that probability occurrence, Wave-particle duality and uncertainty of a particle exists only when there is comparable size between the particle and its barrier width.
A Study of Lognormal Model for Air Pollution Concentration
Authors: Bhandari Prem Sagar
Published: February 2022

The Lognormal distribution has been widely used to represent the type of air pollutant concentration distribution. There are different methods to estimate the distribution parameters such as the method of moments, percentiles, maximum likelihood estimation (MLE) and Bayesian method of estimation. In this study, the theoretical distribution Lognormal is used to fit the parent distribution of PM 10 of Putalisadak of Kathmandu, Nepal. Two estimating methods namely method of maximum likelihood and method of moments are used to estimate the parameters of the theoretic distributions.
Regional Imbalance in the Levels of Development in Bagalkot District- Karnataka: A Spatial Analysis
Authors: Nayak L.T. , Ajjodi B.D.
Published: February 2022

After independence India has made remarkable progress in the socio-economic status of the people. But the attainment of this has spread highly uneven among the urban and rural areas. Regional imbalances are common phenomenon in the world, which occurred across different continents, countries and regions in different extent and India is not exception in this context. This phenomenon spread among inter-regions, inter-states and intra-states n India. This resulted into uneven development in the country. This process of imbalance is not exception in Bagalkot district. There are three major rivers namely the Krishna, the Malaprabha and the Ghataprabha and their tributaries flow in the study area and play important role in the development of the district. However, the study reveals that there exists a wide imbalance in the level of socio-economic development in the region. In view of this, an attempt has been made in this research work to evaluate and compares temporal growth and spatial pattern of disparities in the levels of socio-economic development at block level in Bagalkot district. Correlation coefficient technique has been applied to understand the correlation between different factors which are responsible for widening the regional imbalance. To analyses the regional imbalance of six taluks of Bagalkot district, 23 social, economic and demographic indicators have been considered. The present paper is based on secondary information based on which the socio-economic imbalance among the taluks of the district is made with the help of composite development index for two time of point i.e. 1997 and 2017 data. It has been observed that the social indicator values varied from 11 to 27. The study period witnessed Bagalkot, Badami, Hunagund and Jamkhandi are the three taluks which represent high social development, whereas low (< 11) social development was observed in Bilagi taluk. The outstanding causes for this backwardness are are, less number of education institutes, communication centers, adult education centers, health centers, family planning centers, recreational centers etc. The observed values of economic development are ranging between 19 and 35. It had been observed in only two taluks viz Bilagi and Hungund were found in high economic development, and low economic development was recorded in Jamakhandi taluk. Bagalkot, Mudhol and Badami taluks registered under relatively developed range. Lastly to understand the overall development, the observed values of socio-economic, economic and infrastructure indicators are added and derived a separate composite index.
Non-Formal Environment al Education and NGO-School Link for Environmental Awareness and Protection
Authors: Choudhury Kabita
Published: February 2022

The protection and improvement of human environment is a major issue which affects the wellbeing of people and economic development throughout the world. In this rapidly changing man-made environment the need of restoring the originality of natural environment becomes a deep concern for the whole mankind. Lack of awareness, proper knowledge among the common people regarding the conservation of environment and its resources can lead to different socio-ecological and environmental problems. Unless the environmental education is reached to the grass root level and cover all sections of people no efforts on environmental protection can be expected. Therefore environmental education is designed as a lifelong process covering all sections of people and it is expected that environmental education will provide a fundamental understanding of bio-physica1 environmental problems confronting man, how these problems can be solved with sound knowledge and attitude. The life-long environmental education is known as the non-formal environmental education and it is designed for any age group, participating in social, economic, cultural development of the community. The present study tries to discuss the importance of NGOs and its linkage with the secondary schools in environmental awareness and protection as the N0n-governmental Organizations constitute an integral part of non-formal environmental education.

Published: February 2022

The advertisement of OTC drugs plays a very important role in sale of OTC drugs in India and influence the buying decision in some aspect. The drug and magic remedies Act of 1954 and 1955 prevent advertisement of certain products that require consumption only under medical supervision. This was done in a view to prevent the self-medication for an ailment. In India the OTC drugs are allowed to be aired and are endorsed by many celebrities. Celebrities in India have a huge impact on people, so any product that is promoted by their favourite celebrity, compels them to buy that product. The impact of advertisement on sale of OTC drugs is an important subject to be studied and also to be taken into consideration that what are the most impactful ways to advertise a product. In this research we are studying the impact of advertisement of OTC products on consumer behaviour and their spending in OTC products.
Staff of Life: Preserving Yeast, Memory, and Humanity
Authors: Szanto David
Published: February 2022

The line between life and death is blurry. For one organism to live, others must die, turning first into food, then units of energy, and then fodder for new life. Performance itself is a play between liveliness and stabilizations, sensory immediacy and documented pasts. In the culture and practice of food, parallels abound. A notable yet humble example is witnessed in fermentation practice and the use of starter cultures, whether bacterial, yeasty, or both. Even as such cultures are consumed by a production process, they are renewed by it. This autoethnographic account of a cycle of three performances centred on an inherited sourdough starter explores the ways in which performance with food can act as a process of preservation, as well as an exploration of life, death, and states of being that may exist in between. In using a yeast culture that is more than 25 years old, I have attempted not only to perpetuate the tiny bodies within the flour-water paste but also to embody in a larger way the attitude and essence of the culture’s original user. Probing the preservation of humanness through food practice and artistic improvisation, I propose an alternate sense of memory, ecology, and mortality.
