This thematic issue invites its readers to reflect upon two central questions. If we speak about socialist and post-socialist television in Europe, then: What is ‘socialist’ about television in Europe? How do we approach ‘television’ in (post)socialist Europe? These questions come with issues of definition, approach and positioning of this area of study within a broader European agenda.
East and West on the Finnish Screen
Authors: Pajala Mari
Published: May 2020

Research on Finnish television history has so far emphasized Western influences. However, the Finnish television environment was also in many ways shaped by contacts with socialist television cultures. This article analyses the first volume (1960) of the television magazine Katso to trace the various transnational relations which shaped the early Finnish television environment and to discuss the cultural meanings of socialist television in this environment. Nearly every issue of Katso in 1960 discusses television in a transnational context. Transnational themes fall into four categories: (1) learning about television in other countries; (2) the Eurovision and Nordvision networks; (3) watching television across national borders (Swedish and Tallinn television but also television across surprising distances); and (4) visions of world television. Katso’s understanding of television emphasises the literal meaning of television, to see far. The magazine sets no clear limits to what television could do in terms of overcoming physical distance and ideological borders. The magazine avoids overt politics in discussing television from both the West and the East and represents Tallinn television as a potential source of popular television for Finnish audiences.
Multiple Faces of the Nostalgia Channel in Russia
Authors: Kalinina Ekaterina
Published: May 2020

Through the discourse on nostalgia and media’s role in the production of the content the producers and the audiences created a clear-cut division, stressing that relations to the past become essential markers of their identity in terms of political views. At that, relating to the past with “restorative” nostalgic aspirations, not being selective in the viewed content and not being able to question what was shown in the media, was seen as a sign or consequences of sickness, some kind of pathology, brought into life by inability to adjust to the changing world. At the same time, production of new content, where past is questioned, as well as broadcasting of the content, which previously had been shown on soviet television, were seen as educational practice. In this respect, the Nostalgia channel can be seen both as a sickness and as a remedy. It all depends on the position of the one, who defines what nostalgia is.

Hacia una deconstrucción de la unión mujer-madre
Authors: Giallorenzi María Laura
Published: May 2020

Este trabajo propone un abordaje sobre la maternidad basado en los campos disciplinares de la filosofía, la sociología, la historia y la psicología, así como de los estudios sobre género y las teorías desarrolladas por los feminismos. En este sentido, en un primer apartado, se busca definir y caracterizar a la maternidad, poniendo en discusión ciertos enfoques que, desde diversas perspectivas, han centrado su mirada crítica en la asociación unívoca entre mujer y maternidad y la reducción de la feminidad a la maternidad que se ha ido construyendo a lo largo de la historia. En un segundo apartado, se plantea como alrededor de la maternidad se gestan algunas discursividades y operaciones culturales que tienden a perpetuar la unión mujer-madre. Para dar lugar al desentrañamiento de dichas operaciones culturales, se profundiza en la construcción socio-política de la maternidad, y con ella de las categorías de: maternalizacion de las mujeres, maternazgo y maternalismo. Este análisis, permite situar cómo se fueron gestando diferentes sistemas de legitimación de la maternidad como destino para todas las mujeres. El objetivo de pensar y conceptualizar a la maternidad bajo estas lecturas críticas, está dado en buscar, que la maternidad signifique también una experiencia de emancipación para las mujeres y un espacio por el cual obtener los derechos necesarios para ejercer dicho rol.

Published: May 2020

O desafio de compreender o papel e o sentido das estratégias desenvolvidas pelo ISEB - Instituto Superior de Estudos Brasileiros, criado como órgão vinculado ao MEC em 1955, parte do entendimento das sociedades modernas como bloco histórico - a unidade diversa entre estrutura e superestrutura. No Brasil, os anos de 1950 foram palco de um gradual processo de consolidação do modelo econômico e concomitante processo de democratização e politização da sociedade civil que resultou na reconfiguração do papel do Estado capitalista brasileiro; o ISEB se constituiu parte dessas mudanças necessárias ao novo papel do Estado. Concebido como um núcleo de assessoramento estratégico, o ISEB resultou da iniciativa de um grupo de intelectuais, com significativa notoriedade e influência política, que colocou seus estudos acadêmicos a serviço da compreensão dos problemas brasileiros, tendo em vista as “[...] tarefas e matérias que o moderno Estado capitalista é incumbido de realizar.” (TOLEDO, 1997, p. 184). Mas a despeito de se constituir num centro de estudos dos problemas nacionais, os isebianos não tiveram voz ativa na máquina governamental; sua atuação se destacou no fomento e no desenvolvimento de estratégias educativas e formativas de natureza pós-universitária, voltadas à formação de intelectuais orgânicos disseminadores de determinado projeto de nação - o “nacional-desenvolvimentismo”. O objetivo do presente trabalho é compreender o papel do ISEB e o sentido do uso dessas estratégias educativas e formativas de natureza pós-universitária, seu legado acadêmico nas novas gerações de intelectuais e seu impacto político (in)direto nas novas formas de construção de entendimento e interpretação do Brasil.

Este artigo produzido com enfoque na discussão historiográfica objetiva refletir sobre o processo de constituição histórica da escola de tempo integral no Brasil, por isso partiu da problemática: as políticas públicas para a educação têm possibilitado a instituição da educação de tempo integral no sistema de ensino brasileiro? Metodologicamente, a pesquisa é de cunho bibliográfico, fomos buscar nos teóricos que discutem a temática fundamentos para determinar a conceituação desse modelo educacional que vem sendo discutido e implementado de forma gradativa desde o início do século XX. Os principais resultados apontam que a conceituação de educação integral e de tempo integral tem sofrido variação, influenciado pelo contexto histórico, econômico e político em que a política é formulada. A oferta desse modelo educacional também sofre alteração no decorrer do tempo por vários fatores, dentre eles, principalmente, em virtude das políticas públicas de Educação de Tempo Integral não terem sido prioridades no cenário educacional brasileiro, embora seja uma exigência dos Planos Nacionais de Educação e uma reivindicação dos movimentos educacionais desde o começo do século passado. Concluímos que a educação em tempo integral ainda é um direito que precisa ser conquistado, embora se reconheça que vários passos, de forma isolada, já foram dados nesse sentido, do século passado até os dias atuais.

Published: May 2020

Rural areas, according to Law Number 6 of 2014 concerning Villages, are placed as the economic power behind the villages themselves, especially concerning the agricultural sector. Ideally, the village focused on the development of the agricultural sector. However, there are 158 factories in Purbalingga Regency located in rural areas. While the protection of the rural areas and the spatial planning of industry is unclear, there are conflicts primarily related to the designation of rivers, irrigation canals, agricultural features, settlements, and water and air pollution. This research explains the study of industrial space and the related functional arrangements, especially in the agriculture-based rural and industrial areas of Purbalingga. This paper based on the research results, which were determined using qualitative methods and a case study approach. The data collected through observations, a document-based study, and interviews. The informant selection techniques used were purposive and snowball. Data validity was confirmed using an interactive analysis model. This study interviewed eleven informants who were from the Agricultural Office in addition to the Chief of the Urban Village, a Former Chief of the Village, a Former Chief of the Urban Village, a Chief from Village, Village Officers, Public Society Institution activists, and affected farmers. The results of the study are as follows 1) Purbalingga Government has an unclear vision concerning its long-term planning for industrial areas. The lack can see it of harmony present in the development of rural and industrial areas causing conflict between the actors involved, 2) the high investment from Purbalingga Government brings in a new problem, which is the neglecting of both the agricultural and environmental interests present. This research concludes, the government allowed for the development of rural areas that otherwise prioritized the development of the industrial sector. It is done without considering spatial planning, causing a sustained conflict between the actors.
May peppery wines be the spice of life? A review of research on the ‘pepper’ aroma and the sesquiterpenoid rotundone
Authors: Geffroy Olivier , Kleiber Didier , Jacques Alban
Published: May 2020

Rotundone is the main aroma compound responsible for peppery notes in wines. Since its discovery in 2008, this potent and fascinating odorant has been the subject of many research studies worldwide. The aim of this review is to summarize these works. Rotundone is a rather ubiquitous molecule that has been detected in many grape varieties. As with other sesquiterpenes, the proposed biosynthetic scheme for rotundone involves both the methylerythritol phosphate (MEP) and the mevalonate (MVA) pathways. The production of the compound by the plant, which could be a response to biotic stress, is also affected by abiotic factors. In most cases, studies showed that rotundone was neutrally or positively perceived by consumers, which makes the peppery note a desirable character in vine. Practical ways were identified to modulate rotundone levels in wines using viticultural and enological techniques. Climate change, through the expected alteration of precipitation regime and a rise in temperature over the grape maturation period, should have a depreciative impact on rotundone accumulation. Adaptation strategies in this context, together with other perspectives of research, are discussed in concluding this review.
Effect of Non-Linear Electrodynamics on Weak Field Deflection Angle by Black Hole
Authors: Javed Wajiha , Hamza Ali , Övgün Ali
Published: May 2020

In this work, we investigate the weak deflection angle of light from exact black hole within the non-linear electrodynamics. First we calculate the Gaussian optical curvature using the optical spacetime geometry. With the help of modern geometrical way popularized by Gibbons and Werner, we examine the deflection angle of light from exact black hole. For this desire, we determine the optical Gaussian curvature and execute the Gauss-Bonnet theorem on optical metric and calculate the leading terms of deflection angle in the weak limit approximation. Furthermore, we likewise study the plasma medium's effect on weak gravitational lensing by exact black hole. Hence we expose the effect of the non-linear electrodynamics on the deflection angle in the weak gravitational field.
Potential Role of Cellular Senescence on Coronavirus Infections
Authors: Chapagain Prem
Published: May 2020

The disproportionate incidences of COVID-19-related hospitalization and mortality for different age groups and various underlying health conditions is a result of a complex social predisposition to the exposure, resistance, and tolerance for the infection. Based on the observed data as well as the molecular mechanisms for viral entry and replication, cellular senescence related to aging, obesity, hypertension, and diabetes appears to be strongly correlated with the SARS-CoV-2 infections resulting in higher COVID-19 related complications and mortality. Establishing such a correlation may allow us to better explain the pathobiology as well as the differential nature of the SARS-CoV-2 infections and consider targeted control and therapeutic strategies to combat the disease.

Published: May 2020

SARS-CoV-2 is a new coronavirus that has caused a worldwide pandemic. It produces severe acute respiratory disease (COVID-19), which is fatal in many cases, characterised by cytokine release syndrome (CRS). According to the World Health Organization (WHO), those who smoke are likely to be more vulnerable to infection. Here, in order to clarify the epidemiologic relationship between smoking and COVID-19, we present a systematic literature review until 28 April 2020 and a meta-analysis. It includes 18 recent COVID-19 clinical and epidemiological studies based on smoking patient status from 720 initial studies in China, USA, and Italy. The percentage of hospitalised current smokers was 7.7% (95%CI: 6.9-8.4) in China, 2.3% (95%CI: 1.7-2.9) in the USA and 7.6% (95%CI: 4.2-11.0) in Italy. These percentages were compared to the smoking prevalence of each country and statistically significant differences were found in them all (p <0.0001). By means of the meta-analysis, we offer epidemiological evidence showing that smokers were statistically less likely to be hospitalised (OR=0.18, 95%CI: 0.14-0.23, p<0.01). CRS and exacerbated inflammatory response are associated with aggravation of hospitalise patients. In this scenario, we hypothesise that nicotine, not smoking, could ameliorate the cytokine storm and severe related inflammatory response through the cholinergic-mediated anti-inflammatory pathway.

Authors: Radfar Soheil , Panahi Roozbeh
Published: May 2020

Tidal stream energy, due to its high level of consistency and predictability, is one of the feasible and promising type of renewable energy for future development and investment. Applicability of Blade Element Momentum (BEM) method for modeling the interaction of turbines in tidal arrays has been proven in many studies. Apart from its well-known capabilities, yet there is scarcity of research using BEM for the modeling of tidal stream energy farms considering full scale rotors. In this paper, a real geographical site for developing a tidal farm in the southern coasts of Iran is selected. Then, a numerical methodology is validated and calibrated for the selected farm by analyzing array of turbines. A linear equation is proposed to calculate tidal power of marine hydrokinetic turbines. This methodology narrows down the wide range of turbine array configurations, reduces the cost of optimization and focuses on estimating best turbine arrangements in a limited number of positions.

Effects of the convection flow, atmospheric diffusivity and humidity on evolution and travel distances of exhaled aerosol clouds by an infected person are considered. The aim of this work is to evaluate the importance of aerosol transmission routes and the effectiveness of the 2-metre separation distance policy. A potential impact of use of face masks on the infection transmission rate, and an opportunity to reduce infection in hospitals, care homes and other public spaces by appropriate monitoring and filtering of air are also considered. The results obtained demonstrate that aerosol particles generated by coughing and sneezing can travel over 30 m. Modelling of the evolution of aerosol clouds generated by coughing and sneezing enables us to evaluate the deposition dose of aerosol particles in healthy individuals. For example, a person in a public place (e.g. supermarket or car park) can accumulate in the respiratory system up to 200 virus copies in 2 min time by breathing in virus laden aerosols. Wearing face mask considerably reduces the deposited load down to 2 virus copies per 2 min. The modelling also suggests that it should be possible to measure Covid-19 within aerosol particles in hospitals and public places, e.g. care homes and supermarkets.

The aims of this paper are twofold. First, it is shown, for the first time, which types of nonsmooth functions are characterized by all vector critical points as being efficient or weakly efficient solutions of vector optimization problems in constrained and unconstrained scenarios on Hadamard manifolds. This implies the need to extend different concepts, such as the Karush--Kuhn--Tucker vector critical points and generalized invexity functions, to Hadamard manifolds. The relationships between these quantities are clarified through a great number of explanatory examples. Second, we present an economic application proving that Nash's critical and equilibrium points coincide in the case of invex payoff functions.

Published: May 2020

Aim: The overall aim of the study was to assess the reasons and experiences of participants involved in Antibody Mediated Prevention (AMP) HIV prevention clinical trial at University of North Carolina (UNC) Project, Lilongwe, Malawi. We determined the participants’ reasons for participating in HIV Prevention clinical trials; and the experiences of participants in HIV Prevention clinical trials. Methods: We adopted the qualitative cross-sectional study method. Data were collected using in-depth interviews (IDIs). Purposive sampling was used to select 12 study participants who consented to take part in the study. All participants were the ones taking part in the AMP HIV prevention study at the UNC Project. Data analysis was done concurrently with data collection using content analysis. Results: Individuals were motivated to participate in HIV research due to a range of perceived benefits. These included personal, health, and financial benefits. Participants' research experiences and their continued participation in HIV research were influenced by the research clinic context and the nature of their interactions with research staff. Conclusion: When the clinical trial study participants’ expectations are met through what they experience in the study, the chances of them adhering to the study visits and procedures are high. Even for those who did not have any expectations prior to the study, feeling welcomed and being able to open up to the study staff encouraged their continued participation. In the end, this outweighed the negative comments made by the people in their communities or their friends
Cytotoxicity and Mitochondrial-Mediated Apoptosis Induced by Ethanolic Leaf Extract of Barleria lupulina Lindl. in Human Leukemia Cells Via Reactive Oxygen Species Generation
Authors: Kumari Reshma , Kumar Sanjay
Published: May 2020

Background: Barleria lupulina Lindl. (Hop-headed) is a small shrub, possess potent anti-inflammatory, analgesic, anti-leukemic, antitumor, anti-hyperglycemic, anti-amoebic, virucidal, diuretic, bactericidal and antibiotic properties. Methods: Cytotoxicity, bioactive assay and genetic analysis of B. lupulina were investigated in the present communication. The leaf extract was investigated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT), Neutral red uptake (NRU), DNA fragment, reactive oxygen species (ROS) generation, mitochondrial membrane potential (MMP) assay, gene expression analysis and cDNA synthesis to evaluate anti-cancerous potency using cancerous THP-1 cell lines in vitro and in vivo. Results: HPTLC analysis reveals four spots and GC-MS analysis displayed the presence of eleven bioactive compounds among which benzofuranon, hexadecanoic acid, ethyl 9,12,15-octadecatrienoate, and 3,7,11,15-tetramethyl-2-hexadecanoic acid were the most prominent compounds. The ethanolic extract showed significant cytotoxicity (P<0.5) against THP-1 cell line at a concentration of 1mg/mL. The cells were also observed for apoptosis through DNA fragmentation in B. lupulina treated cells. Conclusions: It can be concluded that if the dose range was further refined within the range of 100-1000 µg/mL there could be dose at which the entire population of the THP-1 cell line would be apoptosis induced. The extract induced ROS in the cells after 30 minutes of exposure displaying cytotoxic effects and DNA fragmentation assay.

SARS-CoV-2 is a novel and highly pathogenic coronavirus, which was first diagnosed in Wuhan city, China, in 2019, and spread to 185 countries and territories, and as of April 29, 2020, more than 3.11 million cases were recorded, and more than 217,000 people were killed. Despite all worldwide efforts, there is currently no vaccine, any drugs available to protect people against deadly SARS-CoV-2 coronavirus. The world urgently needs a SARS-CoV-2 coronavirus vaccine or effective antiviral drugs to relieve the human suffering associated with the pandemic that kills thousands of people every day. The SARS-CoV-2 genome encode a non-structural proteins named as ORF1a/b, and structural proteins such as spike (S) glycoprotein, nucleocapsid protein (N), small envelop protein (E) and matrix protein (M). A number of studies have been shown that CoV spike (S) glycoprotein and nucleocapsid protein (N) could be promising targets for vaccine, antibodies and therapeutic drug development to combat with deadly, pandemic SARS-CoV-2. Purposes of the present paper is the sequence analysis and amino acid variations of structural proteins deduced from novel coronavirus SARS-CoV-2 strains, isolated in different countries. Multiple sequence alignment of S, N and E proteins from four different coronavirus species, are also described. It is expected that the data from these studies will be very useful for the the designing and development of vaccines, antibodies and therapeutic agents that can be used to combat with the highly pathogenic SARS-CoV-2 coronavirus worldwide.

This paper aims to determine the insecticidal activity of Panyawan (Tinospora rumphii) leaf extract against American cockroach (Periplaneta americana). A quantitative experimental research design was employed in the study. Cockroach strains were collected through trapping and hand catch methods. Panyawan leaf was collected and extracted to achieve seven different concentrations. The concentrations and controls were tested against the strains through the standard contact glass jar bioassay. Results revealed that the shortest knock-down time was achieved by the positive control at 1.08 minutes while the Extracts of Panyawan leaf reported a 1.42 to 20.25 minutes knock-down time. Probit Regression reported that the lethal concentration 50 of Panyawan leaf extract was 15.836%. One-Way ANOVA revealed that there is a significant difference in the knock-down times of cockroaches when exposed to different Panyawan leaf extract concentrations, negative and positive controls (p<0.01). Homogeneous subsets derived from Post Hoc Test using Tukey’s Honest Significant Difference reported that there is no significant difference between positive control and Extract 100% (p>0.01).
Thalidomide-Revisited: Are COVID-19 Patients Going to be the Latest Victims of Yet Another Theoretical Drug-Repurposing?

Published: May 2020

The new pandemic coronavirus disease 2019 (COVID-19) is a worldwide threatening health issue. Early progression of this disease starts in the lung airways with an exaggerated inflammation, triggered by the viral infection and characterized by a “cytokine storm” that can lead to lethal lung injuries. In the absence of an effective anti-viral molecule and until the formulation of a successful vaccine, anti-inflammatory drugs might offer a complementary tool for controlling the associated complications and thus decreasing the subsequent fatalities. Drug repurposing for several molecules has emerged as a rapid temporary solution for COVID-19. Among these drugs, Thalidomide, a historically emblematic controversial molecule that harbors an FDA approval for treating Erythema Nodosum Leprosum (ENL) and multiple myeloma (MM). Based on only one-case report of positive outcomes in a patient treated amongst others with Thalidomide, two clinical trials on the efficacy and safety of Thalidomide in treating severe respiratory complications in COVID-19 patients were registered. Conversely, the absence of any substantial, promising evidence on Thalidomide usage in that context along with the discontinued studies on the efficiency of this drug in similar pulmonary diseases might cause a significant obstacle for carrying on clinical studies. In this review, we will discuss the theoretical effectiveness of this drug in attenuating inflammatory complications that are encountered in patients with COVID-19 while pinpointing the lack of evidence that is needed to move forward with this drug.
