ACTIVITIES AND POWERS OF POLICE DIVISIONS ON THE WATER TO ENSURE TRANSPORT SAFETY: PROBLEM ISSUES AND WAYS TO SOLVE THEM
Authors:   Donetsk State University of Internal Affairs, Pylypenko Evheniia
Published: September 2021

The article is devoted to the study of certain aspects of the activities and powers of police units on the water in the field of transport safety by preventing, stopping and responding to administrative offenses, committed by drivers. The powers of the police on the water in accordance with the requirements of the Law of Ukraine “On the National Police”, as well as the Code of Ukraine on Administrative Offenses are described. In particular, the powers of police units on the water include the implementation of preventive and preventive activities aimed at preventing offenses on sea or river transport, identifying the causes and conditions that lead to the commission of criminal and administrative offenses; timely response to statements and notifications of criminal, administrative offenses or events; pre-trial investigation of criminal offenses within the defined jurisdiction; search for persons hiding from pre-trial investigation bodies, investigating judge, court or missing persons; taking measures to ensure public safety and order on the streets, squares, parks, squares, stadiums, railway stations, airports, sea and river ports, and other public places; maintenance of vehicles, etc. The functions and powers of water police units are fully aimed at ensuring public safety and order, protection of human rights and freedoms, as well as the interests of society and the state, combating crime, providing, within the limits prescribed by law, personal assistance services, social reasons or due to emergencies need such assistance. However, the quality of police duties on the water to prevent, stop and combat violations of the law depends on the legislative consolidation of powers to respond to offenses and bring the perpetrator to justice. To do this, based on the analysis of legislation governing the activities of police units on the water, provided proposals to current legislation of Ukraine in the field of transport safety on the water, as well as eliminating certain gaps and shortcomings in the legislation on the possibility of prompt and statutory police response committed on the water.

Published: September 2021

Atrial fibrillation (AF) is the most common heart rhythm disorder with clinical and social significance. The expected increase in the incidence of AF and the high financial costs that occur in the treatment of these patients require a more detailed study of the epidemiological situation on AF in our country. The article provides data on the appeal for emergency medical care (EMC) of patients with AF in St. Petersburg, Gatchina, Sestroretsk, Great Novgorod. The analysis revealed significant seasonal variations in the number of EMC calls: a decrease in the treatment of EMC patients with AF in the summer in St. Petersburg. Gender-age differences were revealed, the general increase in the circulation of elderly and senile women with AF for EMC in St. Petersburg and Leningrad region. In different regions of our country, there are significant differences in statistical accounting methods used in emergency medical facilities. However, in order to obtain full information on the spread of AF, it is advisable to develop uniform statistical methods of accounting (registers) for this group of patients.

Authors: Ostapchuk Pavel
Published: September 2021

Abstract. To develop of sheep breeding in the selected region should be based on the most complete analysis of previous work with sheep breeds. This will allow to plan further stages in the industry. The purpose of the analysis was to study the origin, the main characteristics of sheep breeds on the Crimean Peninsula, their intensification and the purpose of their use on the basis of literary sources. The main research method is periodization, which allows us to analyze the breed composition of sheep in the studied time stages, which allows us to compare the features of the considered stages of the development of the industry on the peninsula. The results of the analysis indicate the fact that the sheep breeds in various historical periods of development of the Crimean Peninsula are an important element of sheep breeding described in the article. The fact that the coarse wool sheep breeding developed extensively and have been focused on getting from sheep's milk and mutton at the end of the XVIII century. Manufacturers in the XIX century on the production of fine wool accent give. Suitable types and breeds of sheep in the practice introduced are Electoral (sheep with superior wool), Electoral-and-Negretti, Negretti, Rambouillet and others. Production of sheep's milk and its products have occupied only peasant farms, where animals are were bred coarse wool and semi-fine wool breeds are Malych, Valachian and Tsigai. Sheep breeding industry develops intensively in the twentieth century in Crimea. Tsigai Breed sheep becomes of the planned. This breed is still the main on peninsula and the present time. The scientific novelty lies in the fact that for the first time a deep historical analysis of the evolution of sheep farming on the Crimean Peninsula since its entry into the Russian Empire at the end of the 18th century was carried out and recommendations for the further development of the industry were given.

A Tracking Method in FM Broadcast-based Passive Radar Systems
Authors: Kiss Ádám , Dudás Levente
Published: September 2021

Passive radars are popular because without the expensive, high-power-rated RF components, they are much cheaper than the active ones, nevertheless, they are much harder to detect from their electromagnetic emission. Passive radars produce so-called RV matrices in an intermediate signal processing step. Although accurate RV matrices are found in DVBT-based passive radars, the characteristics of the FM signals are not always suitable for this purpose. In those situations, further signal processing causes false alarms and unreliable plots, misleads the tracker, and consumes power for processing unnecessarily, which matters in portable setups. Passive radars also come with the advantage of a possible MIMO setup, when multiple signal sources (broadcast services for example) are reflected by multiple targets to the receiver unit. One common case is the stealth aircraft’s which form is designed to reflect the radar signal away from the active radar, but it could also reflect the signals of the available broadcast channels. Only one of these reflected signals could reveal the position of the target.

An Experimental Study on the Force Coefficient and the Discharge Coefficient of a Safety Valve in Air-water Mixture Flow
Authors: Burhani Mhd Ghaith , Hős Csaba
Published: September 2021

Due to the low number of experimental investigations on the sizing of safety valves in multiphase flow, a novel set of measurement data of an air-water mixture is reported. This paper presents an experimental study on three different geometries of safety valves, a poppet valve with jet angle θ = 120°, and two-disc valves with deflection angles θ = 0° and θ = 90°, respectively. Our test rig comprises a pipeline with 42.5 mm inner diameter, spray nozzles to supply the added water quality (water mass fraction) to the pressurized airflow up to 40 % mass fraction and an inlet pressure up to 6.6 bar(g). The time histories of force, valve lift, and pressures were recorded. We present correlation data for the force coefficient and the discharge coefficient. The widely used omega technique for the Homogenous Equilibrium Model (HEM) is employed to predict the theoretical mass flux. The results show that the poppet valve experiences less momentum force and lower mass flow rates compared to disc valves, while the disc valve with deflection angle θ = 90° presents the highest discharged flow rates among the tested geometries. Our most important finding is that up to 60 % relative valve lift and 40 % mass fraction, neither the force nor the discharge coefficient changes significantly compared to the pure-air case. Finally, we propose a new correlation with a single equation for the resultant force and the discharge coefficient as a function of the relative valve lift for all tested water mass fractions.
EVOLVING BUSINESS MODELS IN ORTHOTICS
Authors: Schneider Nancy
Published: September 2021

This submission provides an important historical context for understanding the current challenge facing the Orthotic and Prosthetic community in Alberta including Alberta Aids to Daily Living (AADL), Suppliers, and Providers: maintaining sustainable access to Orthotic care for people with mobility disorders in the face of declining real rates of reimbursement combined with increasing costs and a shortage of skilled Clinicians. Under the Canada Health Act, the federal government delegates responsibility for providing health care to the provinces. This delegation of responsibility to the provinces results in a degree of variability of funding of Orthotics and Prosthetics between provinces across the country. Funding of Orthotics and Prosthetics in Alberta is characterized by structural inequities that favour Prosthetics at the expense of Orthotics. To the extent that the structural inequities that exist in Alberta are related to governance by volunteer-run, non-profit organizations, they may be generalized to the Canadian experience. Finally, in a Call to Action a number of recommendations are made to address the challenge of sustainable access to Orthotic care in Alberta serving as a model for other provinces across Canada.

HEALTH SERVICE DELIVERY AND ECONOMIC EVALUATION OF LIMB LOWER BONE-ANCHORED PROSTHESES: A SUMMARY OF THE QUEENSLAND ARTIFICIAL LIMB SERVICE’S EXPERIENCE
Authors: Frossard Laurent , Berg Debra
Published: September 2021

The emergence of skeletal prosthetic attachments leaves governmental organizations facing the challenge of implementing equitable policies that support the provision of bone-anchored prostheses (BAPs). In 2013, the Queensland Artificial Limb Service (QALS) started a five-year research project focusing on health service delivery and economic evaluation of BAPs. This paper reflects on the QALS experience, particularly the lessons learned. QALS’ jurisdiction and drivers are presented first, followed by the impact of outcomes, barriers, and facilitators, as well as future developments of this work. The 21 publications produced during this project (e.g., reimbursement policy, role of prosthetists, continuous improvement procedure, quality of life, preliminary cost-utilities) were summarized. Literature on past, current, and upcoming developments of BAP was reviewed to discuss the practical implications of this work. A primary outcome of this project was a policy developed by QALS supporting up to 22 h of labor for the provision of BAP care. The indicative incremental cost-utility ratio for transfemoral and transtibial BAPs was approximately AUD$17,000 and AUD$12,000, respectively, per quality-adjusted life-year compared to socket prostheses. This project was challenged by 17 barriers (e.g., limited resources, inconsistency of care pathways, design of preliminary cost-utility analyses) but eased by 18 facilitators (e.g., action research plan, customized database, use of free repositories). In conclusion, we concluded that lower limb BAP might be an acceptable alternative to socket prostheses from an Australian government prosthetic care perspective. Hopefully, this work will inform promoters of prosthetic innovations committed to making bionic solutions widely accessible to a growing population of individuals suffering from limb loss worldwide.

TRENDS AND OPPORTUNITIES IN HEALTH ECONOMIC EVALUATIONS OF PROSTHETIC CARE INNOVATIONS
Authors: Frossard Laurent
Published: September 2021

Overcoming obstacles to prosthetic fittings requires frequent tryouts of sockets and components. Repetitions of interventions are upsetting for users and place substantial economic burden on healthcare systems. Encouraging prosthetic care innovations capable of alleviating clinical and financial shortcomings of socket-based solutions is essential. Nonetheless, evidence of socio-economic benefits of an innovation are required to facilitate access to markets. Unfortunately, complex decisions must be made when allocating resources toward the most relevant health economic evaluation (HEE) at a given stage of development of an innovation. This paper first, aimed to show the importance and challenges of HEEs of intervention facilitating prosthetic fittings. Next, the main trends in HEEs at various phases of product development and clinical acceptance of prosthetic care innovations were outlined. Then, opportunities for a basic framework of a preliminary cost-utility analysis (CUA) during the mid-stage of development of prosthetic care innovations were highlighted. To do this, fundamental and applied health economic literature and prosthetic-specific publications were reviewed to extract and analyse the trends in HEEs of new medical and prosthetic technologies, respectively. The findings show there is consensus around the weaknesses of full CUAs (e.g., lack of timeliness, resource-intensive) and strengths of preliminary CUAs (e.g., identify evidence gaps, educate design of full CUA, fast-track approval). However, several obstacles must be overcome before preliminary CUA of prosthetic care innovations will be routinely carried out. Disparities of methods and constructs of usual preliminary CUA are barriers that could be alleviated by a more standardized framework. The paper concludes by identifying that there are opportunities for the development of a basic framework of preliminary CUA of prosthetic care innovations. Ultimately, the collaborative design of a framework could simplify selection of the methods, standardise outcomes, ease comparisons between innovations and streamline pathways for adoption. This might facilitate access to economical solutions that could improve the life of individuals suffering from limb loss.

A PRELIMINARY COST-UTILITY ANALYSIS OF THE PROSTHETIC CARE INNOVATIONS: BASIC FRAMEWORK
Authors: Frossard Laurent
Published: September 2021

A preliminary cost-utility analysis (CUA) of prosthetic care innovations can provide timely information during the early stage of product development and clinical usage. Concepts of preliminary CUAs are emerging. However, several obstacles must be overcome before these analyses are performed routinely. Disparities of methods and high uncertainty make the outcomes of usual preliminary CUAs challenging to interpret, appraise and share. These shortcomings create opportunities for a basic framework of preliminary CUAs. First, I introduced a basic framework of a preliminary CUA built around a series of constructs and hands-on recommendations. Then, I appraised this framework considering the strengths and weaknesses, barriers and facilitators, and return on investment. The design of the basic framework was determined through the review of health economic and prosthetic-specific literature. A preliminary CUA comparing the costs and utilities between usual intervention and an innovation could be achieved through a 15-step iterative process focusing on feasibility, constructs, analysis, and interpretation of outcomes. This CUA provides sufficient evidence to identify knowledge gaps and improvement areas, educate about the design of subsequent full CUAs, and obtain fast-track approval from governing bodies. Like previous CUAs, the main limitations were inherent to the constructs (e.g., narrow perspective, plausible scenarios, mid-term time horizon, substantial assumptions, data mismatch, high uncertainty). Key facilitators potentially transferable across preliminary CUAs of prosthetic care innovations included choosing abided constructs, capitalizing on prior schedules of expenses, and benchmarking baseline or incremental utilities. This new approach with preliminary CUA can simplify the selection of methods, standardize outcomes, ease comparisons between innovations, and streamline pathways for adoption. Further collegial efforts toward validating standard preliminary CUAs will facilitate access to economic prosthetic care innovations, improving the lives of individuals suffering from limb loss worldwide.

A PRELIMINARY COST-UTILITY ANALYSIS OF THE PROSTHETIC CARE INNOVATIONS: CASE OF THE KEEP WALKING IMPLANT
Authors: Guirao Lluis , Samitier Beatriz , Frossard Laurent
Published: September 2021

Several obstacles must be overcome before preliminary cost-utility analyses (CUA) of prosthetic care innovations can be routinely performed. The basic framework of preliminary CUAs and hands-on recommendations suggested previously might contribute to wider adoption. However, a practical application for an emerging intervention is needed to showcase the capacity of this proposed preliminary CUA framework. This study presented the outcomes of preliminary CUA of the distal weight bearing Keep Walking Implant (KWI), an emerging prosthetic care innovation that may reduce socket fittings for individuals with transfemoral amputation. The preliminary CUAs compared the provision of prosthetic care without (usual intervention) and with the KWI (new intervention) using a 15-step iterative process focused on feasibility, constructs, analysis, and interpretations of outcomes from an Australia government prosthetic care perspective over a six-year time horizon. Baseline and incremental costs were extracted from schedules of allowable expenses. Baseline utilities were extracted from a study and converted into quality-adjusted life-year (QALY). Incremental utilities were calculated based on sensible gains of QALY from baselines. The provision of the prosthetic care with the KWI could generate an indicative incremental cost-utility ratio (ICUR) of -$36,890 per QALY, which was $76,890 per QALY below willingness-to-pay threshold, provided that the KWI reduces costs by $17,910 while increasing utility by 0.485 QALY compared to usual interventions. This preliminary CUA provided administrators of healthcare organizations in Australia and elsewhere with prerequisite evidence justifying further access to market and clinical introduction of the KWI. Altogether, this work suggests that the basic framework of the preliminary CUA of a prosthetic care innovation proposed previously is feasible and informative when a series of assumptions are carefully considered. This study further confirms that preliminary CUAs prosthetic care interventions might be a relevant alternative to full CUA for other medical treatments.

The Hispanic/Latino population is the second largest racial/ethnic group in the continental United States and Hawaii, accounting for 18% (60.6 million) of the total population. An additional 3 million Hispanic Americans live in Puerto Rico. Every 3 years, the American Cancer Society reports on cancer occurrence, risk factors, and screening for Hispanic individuals in the United States using the most recent population‐based data. An estimated 176,600 new cancer cases and 46,500 cancer deaths will occur among Hispanic individuals in the continental United States and Hawaii in 2021. Compared to non‐Hispanic Whites (NHWs), Hispanic men and women had 25%‐30% lower incidence (2014‐2018) and mortality (2015‐2019) rates for all cancers combined and lower rates for the most common cancers, although this gap is diminishing. For example, the colorectal cancer (CRC) incidence rate ratio for Hispanic compared with NHW individuals narrowed from 0.75 (95% CI, 0.73‐0.78) in 1995 to 0.91 (95% CI, 0.89‐0.93) in 2018, reflecting delayed declines in CRC rates among Hispanic individuals in part because of slower uptake of screening. In contrast, Hispanic individuals have higher rates of infection‐related cancers, including approximately two‐fold higher incidence of liver and stomach cancer. Cervical cancer incidence is 32% higher among Hispanic women in the continental US and Hawaii and 78% higher among women in Puerto Rico compared to NHW women, yet is largely preventable through screening. Less access to care may be similarly reflected in the low prevalence of localized‐stage breast cancer among Hispanic women, 59% versus 67% among NHW women. Evidence‐based strategies for decreasing the cancer burden among the Hispanic population include the use of culturally appropriate lay health advisors and patient navigators and targeted, community‐based intervention programs to facilitate access to screening and promote healthy behaviors. In addition, the impact of the COVID‐19 pandemic on cancer trends and disparities in the Hispanic population should be closely monitored.

Authors:   CEMI Russian Academy of Sciences, Varshavsky L.E.
Published: September 2021

The article illustrates the possibility of using models of chemical kinetics in the analysis and forecasting of real economic systems. It is shown that the model of competition of firms focused on the maximum possible growth has much in common with models describing the processes of competition of chemical components, in particular, the processes of production and destruction of inorganic substances. Examples of the use of a simplified model of nuclear reactor kinetics in the analysis and forecasting of innovative processes in the scientific and technical sphere, new mobile wireless communication technologies, as well as in solving the acute problem of waste (for example, plastic waste) are considered.

Abstract: Education as an important aspect, in improving the quality of education needs to be done innovatively. Learning Models are examples of student learning patterns or structures that are designed, implemented, and systematically evaluated by teachers in order to achieve learning objectives. The Industrial Revolution 4.0 currently has an influence in various fields, one of which is the world of education, with IoT presenting an industrial revolution in the world of education in finding ways to implement learning systems so that they are not outdated. STMIK Royal is one of the computer high schools in Kisaran that wants to develop a better learning model for its students. In choosing the development of learning models requires a decision support system method in choosing the best using the AHP method. This method can analyze a number of criteria and alternatives in choosing the best learning model development which is determined through the calculation process. This model is easier and more effective to produce the best. The AHP method is able to produce the selection of learning model development with several selection criteria and influential alternative choices. The result of the highest ranking is a priority on criteria and alternatives in achieving the goal of choosing a learning model at STMIK Royal Kisaran. Keywords: alternative; analytical hierarchy process; criteria, development; learning models  Abstrak: Pendidikan sebagai aspek penting, dalam peningkatan mutu pendidikan perlu dilakukan secara inovatif.

‘La Main négative’: Limit-Case and Primal Scene of Art
Authors: Malt Johanna
Published: September 2021

Negative handprints or hand-stencils, which occur in many prehistoric sites around the world, occupy a particular place in accounts of rock art. Although they frequently occur alongside paintings, their indexical status as imprints leads them to be treated separately from other types of representations that are more easily accepted as such. This article argues that the negative handprint operates as a kind of limit-case for definitions of art. I examine how it has given rise to imagined scenarios of making — what we might call primal scenes of art — by writers including Georges Bataille, Maurice Blanchot and Marguerite Duras. While its logic of presence invites us to think about it as a point of origin, a trace that connects us to our earliest human ancestors, I show how it can be read against that logic of presence through the lens of one particular ‘primal scene’, that imagined by Jean-Luc Nancy. In this reading, it is precisely the question of absence or distance that gives the handprint its status as a point of origin that undoes the very idea of origins.
The Great Prehistoric Art Swindle: André Breton and Palaeolithic Cave Painting
Authors: Smith Douglas
Published: September 2021

At Pech Merle in 1952, André Breton provoked a controversial incident by damaging a Palaeolithic wall painting that he suspected to be a fake. This episode provides an insight into the contested status of prehistoric sites in post-war France and the theoretical and ideological implications of their cultural mobilization. Such sites allowed for a disavowal of wartime trauma and supported the reaffirmation of French national identity and its civilizing mission by locating the birthplace of human culture on French soil. Yet their extreme age also threw into relief the relative fragility of the recently invented nation-state. Breton's vandalism cast doubt on the models of cultural progress and pre-eminence that sought to instrumentalize prehistoric art but failed to appreciate the subversiveness of its ‘deep’ history. Ironically, however, Breton's scepticism ultimately enhanced the subversive dimension of archaeology by allowing it to demonstrate the authenticity and age of cave art.
Prehistoric Cave Art: From Image to Graphic Narration
Authors: Azéma Marc
Published: September 2021

This article examines cave art in France, arguing that the images created at many sites, but particularly Chauvet, can be analysed in terms of animation, storytelling, lighting and sound. Through superimposition and juxtaposition, and using the contours of the rock face, Palaeolithic artists invented a form of narration based on images, often then animated by the flickering light of lamps and torches. Drawing on semiological work by Philippe Sohet and his terms ‘narrative image’ and ‘iconic narration’, the article sees panels of cave art as constituting scenes and actions that can be discussed in relation to both bande dessinée and cinema. Finally, evidence suggests that the spectacles produced in these spaces, whatever their elusive meaning, also depended on sound and acoustics.
Expression of Biofilm-Degrading Enzymes in Plants and Automated High-Throughput Activity Screening Using Experimental Bacillus subtilis Biofilms

Biofilm-forming bacteria are sources of infections because they are often resistant to antibiotics and chemical removal. Recombinant biofilm-degrading enzymes have the potential to remove biofilms gently, but they can be toxic toward microbial hosts and are therefore difficult to produce in bacteria. Here, we investigated Nicotiana species for the production of such enzymes using the dispersin B-like enzyme Lysobacter gummosus glyco 2 (Lg2) as a model. We first optimized transient Lg2 expression in plant cell packs using different subcellular targeting methods. We found that expression levels were transferable to differentiated plants, facilitating the scale-up of production. Our process yielded 20 mg kg−1 Lg2 in extracts but 0.3 mg kg−1 after purification, limited by losses during depth filtration. Next, we established an experimental biofilm assay to screen enzymes for degrading activity using different Bacillus subtilis strains. We then tested complex and chemically defined growth media for reproducible biofilm formation before converting the assay to an automated high-throughput screening format. Finally, we quantified the biofilm-degrading activity of Lg2 in comparison with commercial enzymes against our experimental biofilms, indicating that crude extracts can be screened directly. This ability will allow us to combine high-throughput expression in plant cell packs with automated activity screening.
