This paper examines the data collected from the power industry over the last six years of actual reported emissions of sulphur hexafluoride (SF6) and the potential impact. The SF6 emissions have been collated from the 14 different regions in England, Scotland, and Wales (Great Britain) from the six distribution network operators. The emissions of SF6 due to the transmission network of Great Britain have also been collated from the three different transmission network operators. By collecting this SF6 emissions data from the power industry, in both the distribution and transmission networks, an overall view of the scale of SF6 emissions in Great Britain can be evaluated. Data from the power industry also shows the inventory of SF6 power equipment in use over the last six years in Great Britain and shows the calculated percentage leakage rate of all of this equipment. In this paper, these figures, as reported by the electrical power industry to the UK government, have been used to estimate the likely inventory of SF6 equipment in England, Scotland, and Wales by 2050 and the future emissions of SF6 that could be leaked into the atmosphere by this equipment.

This article draws on the 2018 Writers Guild of Great Britain report ‘Gender Inequality and Screenwriters’, and original interviews with female screenwriters, to assess how the experience of genre plays out in the UK television industry. The report focuses on the experience of women, as a single category, but we aim to reveal a more intersectional understanding of their experiences. Our aim is to better understand the ways in which women are, according to the report, consistently ‘pigeonholed by genre and are unable to move from continuing drama or children’s programming to prime-time drama, comedy or light-entertainment’. Considering the cultural value of genre in relation to screenwriting labour and career progression, we analyse how genre shapes career trajectory, arguing that social mobility for female screenwriters is inherently different and unequal to that of their male counterparts.

Background: Hokkaido was the first Japanese prefecture to be affected by COVID-19. Since the beginning of the pandemic, the Japanese government has been publishing the information of each individual who was tested positive for the virus. Method: The current study analyzed the 1269 SARS-CoV-2 cases confirmed in Hokkaido in order to examine sex-based differences in symptomology and infectiveness, as well as the status of reinfections and the viral transmission networks. Results: The majority of asymptomatic patients were females and older. Females were 1.3-fold more likely to be asymptomatic (p < 0.001) while a decade of difference in age increased the likelihood of being asymptomatic by 1% (p < 0.001). The data contained information up to quaternary viral transmission. The transmission network revealed that, although asymptomatic patients are more likely to transmit the virus, the individuals infected by asymptomatic cases are likely to be asymptomatic (p < 0.001). Four distinct co-occurrences of symptoms were observed, including (i) fever/fatigue, (ii) pharyngitis/rhinitis, (iii) ageusia/anosmia, and (iv) nausea/vomiting/diarrhea. The presences of diarrhea (p = 0.05) as well as nausea/vomiting (p < 0.001) were predictive of developing dyspnea, i.e., severe disease. About 1% of the patients experienced reinfection. Conclusions: Sex and symptomatology appear to play important roles in determining the levels of viral transmission as well as disease severity.

Transition to digital technologies in management of power industry at all levels – an inevitable consequence of the technical progress which has generated opportunities for diversification, decarbonization and decentralization. Thus it is necessary to recognize that digitalization in power industry is NOT automation, and first of all creation of new business models, services and the markets with a support on possibility of digital economy. In this article questions of transformation of architecture of power industry, and also the main restrictions are considered: absence in regulatory base of new opportunities for consumers; general system inefficiency; impossibility “to legalize” appearance of new subjects (active consumers and prosumers, operators of micropower supply systems and aggregators of the distributed power objects, various service organizations), and also to deregulate the relations between them, to standardize interaction interfaces with EEC, to transform the energy markets.In article it is offered for transition to new digital power to make corresponding changes to the legislation: to enter new type of participants of the market (the active consumer, an active power complex), operated intellectual connection carrying out the standard with the electrical power system, completely responsible for management of the power supply and thus having the minimum regulatory restrictions on organizational model of the work; to improve rules of functioning of trade systems for creation of the markets of the distributed power providing an effective exchange of goods and services between traditional participants of the markets and participants of new type; to enter possibility of application of technologies of the coordinated management of the distributed sources and consumers of energy, systems of storage of energy, means of regulation of loading (“aggregators”) for the purpose of increase of efficiency of their use and participation in the electric power and power markets, including rendering system services and performance of other functions in these markets (the pilot project of such system is realized under the leadership of the author of the present article by subsidiary PAO “Lukoil” “Energy and gas of Romania”); to increase technological and economic flexibility of conditions on reliability and quality of power supply, creation of possibility of a choice by the consumer of conditions of power supply necessary for him and the account them in cost; to enter the accounting of the opportunities given by “new” decisions, at an assessment, formation and implementation of investment programs of the adjustable companies (including introduction of a technique of an assessment of investment projects at possession cost on all life cycle of the decision); to replace cross subsidizing of the population by industrial consumers with mechanisms of address social support and / or with system of restriction of volumes of consumption on reduced rates (“соцнорма”); to refuse further deployment of system of subsidizing of power supply of one regions at the expense of consumers of other regions (as it leads to growth of inefficient power consumption in the subsidized regions, not provided with available generation and infrastructure); to change norms of technical regulation, norms of design on the basis of new technologies; to make changes to programs of development of the infrastructure organizations of power industry taking into account trends of diversification, decentralization, decarbonization and a digitalization; to provide possibility of stimulation, including tariff, implementation of regional programs (pilot and regular), aimed at the complex development of power industry on the basis of new approaches, technologies and the practician, and also the hi-tech companies of small and medium business providing development.

Since 1999, the European Antimicrobial Resistance Surveillance System (EARSS) has monitored the rise in infection due to a number of organisms, including meticillin-resistant Staphylococcus aureus (MRSA). The EARSS reported that MRSA infections within intensive care units account for 25–50 % of infections in many central and southern European countries, these included France, Spain, Great Britain, Malta, Greece and Italy. Each country has defined epidemic MRSA (EMRSA) strains; however, the method of spread of these strains from one country to another is unknown. In this current study, DNA profiles of 473 isolates of MRSA collected from the UK and Malta were determined by PFGE. Analysis of the data showed that two countries separated by a large geographical distance had a similar DNA profile pattern. Additionally it was demonstrated that strains of EMRSA normally found in the UK were also found in the Maltese cohort (EMRSA 15 and 16). A distinct DNA profile was found in the Maltese cohort, which may be a local EMRSA, and accounted for 14.4 % of all Maltese isolates. The appearance of the same MRSA and EMRSA profiles in two separate countries suggests that MRSA can be transferred out of their country of origin and potentially establish in a new locality or country.
