Vitamin K and hip fractures: what do we know?
Authors: Marks Ray
Published: November 2022

Hip fractures among the older adult population remain highly prevalent oftentimes life-threatening events despite decades of efforts to study their causes and implement preventive endeavors. Even more concerning is the possible unabated prevalence of subsequent even more debilitating second or third hip fractures among primary hip fracture survivors. In an effort to explore if indeed there is current evidence of a key overlooked role for vitamin D as far as its probable benefits for preventing or mitigating hip fracture debility and speeding up the optimal recovery post hip fractures goes, this report examines most of the currently available peer reviewed articles listed on the PUBMED data base as of July 1 2021-July 10 2022 and some background material on this topic. It is concluded that while careful usage of vitamin D in cases of risk or deficiency may afford both preventive and optimal recovery opportunities towards reducing the persistent global age-associated hip fracture burden, as well as the burden of acquiring a second or third hip fracture, no current conclusive evidence prevails in this regard.
Recent tendency of frailty and geriatric syndrome for elderly diabetic patients
Authors: Bando Hiroshi
Published: November 2022

Frailty, sarcopenia, geriatric syndrome and diabetes have been in focus. Several types of frailty are present from medical, psychological, and social points of view. The risk of developing diabetic frailty is 1.48 times for meta-analysis. By a systematic review of 15 studies, type 2 diabetes (T2D) patients showed higher sarcopenia risk with odd ratio (OR) 1.55. Concerning the relationship of senile frailty and body composition, male body fat mass correlated with frailty associated with cut off value of 27.6%. Protein intake amount per weight per day was divided into quartile groups. Hazard ratio of mortality for lowest/highest quartile was 2.26. In conclusion, geriatric syndrome may bring generalized various influence to each subject. For patient-centered practice of medicine, personalized medical practice would be required and recommended from now on.

Published: November 2022

Introduction: Skin cancer rate has been associated to UV exposure. According international literature, No report on specific environmental influence on skin cancer in Cuba has been presented. Goal: To search some possible moderator factors, epidemiologically significant, of skin cancer in Cuba. Methods: Information gathered for Cuba was assessed using GIS and least square modelling. Raw Skin cancer rate at municipal scale, possible function of Insolation data obtained from national Network records, demographic, biologic and urbanizing variables was intended to be modelled for the Cuban territory. So, possible linkage between raw skin cancer rate and geophysical, demographic and urbanistic variables were tested. Results: Raw Skin cancer rate did not show a synchronous spatial connection to average skin insolation during time lapse studied, but it was pointed out that proportions of white individuals, elderly and urbanization degree presented moderate strength relationship in Cuba at a municipal level basis, 2000 – 2011. Conclusions: It is possible that some individual and environmental factors may influence disease features in Cuban population, according empirical epidemiological relationships modelled.

Published: November 2022

Toxoplasmosis is a disease that can infect pregnant mothers and women of child bearing age and is transmitted to the unborn baby. The sero-prevalence of toxoplasmosis with its associated risk factors in two hundred and seventy-seven pregnant subjects attending University of Port Harcourt Teaching Hospital was investigated to ascertain the current sero-prevalence status of toxoplasmosis in River State. Blood samples were collected from the subjects through a veno-puncture and the blood tests were performed using the rapid test kits for Toxoplasma gondii IgG and IgM antibodies following manufactures instructions. Commercial pregnancy test kits and HIV test kits were used to confirm their pregnancy and HIV status. Out of the 277 pregnant subjects examined, the overall prevalence was 1.8% (5/277) positive for T. gondii IgG antibody and 6.9% (19/277) positive for HIV. None of the HIV pregnant subjects were positive for toxoplasmosis. All data were presented in frequency and percentages. The chi-square analysis was used to assess the distribution of toxoplasmosis and other variables. All the analysis was done with the Statistical Package for Social Sciences (SPSS) version 25 and a p-value of less than 0.05 was considered significant. The age group of 20 -29 years and 30-39 years had the highest sero- prevalence rates of 3(60%) and 2(40%) respectively for IgG while age group 40-49 years recorded no sero-prevalence. Exposure related sero-prevalence showed that eating of raw vegetables, undercooked meat, and exposure to contaminated soil through farming were more sensitive risk factors associated with toxoplasmosis than others. There was no statistical significance using cat as pets at P>0.05. A Statistical significance difference of toxoplasmosis was higher among the subjects that ate raw vegetables and drank contaminated water (P<0.05) compared to those who ate cooked vegetables and drank treated water. The need for health campaign to enlighten the society and pregnant mothers on the dangers of acquiring toxoplasmosis and how to avoid it is advocated.
Health disparity along the social class gradient of elderly in India

Published: November 2022

Background: Present study attempts to quantify caste-based differentiation in health among elderly individuals in India and role played by social cast the gradient on elderly health. Social classes are detrimental to the health status of the elderly in any society, especially when society is diverse, multicultural, overpopulated, and undergoing rapid unequal economic growth. Data from the Study on global aging and adult health survey (SAGE) is used for the analysis. Methods: Logistic regression, adjusted and unadjusted models are carried out to assess the health disparity among social groups with and without selected background characteristics. The outcome in logistic regression analysis is often coded as 0 and 1, where 1 indicates that the outcome of interest is present, and 0 indicates that the outcome of interest is absent. Results: Other backward caste experience the highest incidence of arthritis followed by other cast group and ST were found lowest, Hypertension is elevated in female and non-educated elderly. Diabetes is prevalent among higher age. Breathing was high in the SC caste, and it was positively related to increases in age while negatively associated with wealth. Conclusion: The result reveals the health status among the elderly in India differs from distinct caste groups. Lower Caste groups experience marginally higher diseases due to their association with manual jobs and lower occupational status. It also shows that health care services do not significantly differ by the caste groups in India. The socio-economic condition is the most critical predictor of influencing health inequality among caste groups in elderly people.
Will the recent emergence of coronavirus mutations precipitate an increase in the incidence of stress disorders among health care professionals?
Authors: Tulp Orien L , Odeyale Rashidat F , Einstein George P , Chance Cheryl
Published: November 2022

The pandemic caused by SARS-CoV-2 (COVID-19) and the recent emergence of the B.1.1.7 and other variant mutations including the recently discovered SARS-CoV-2 VUI 202012/01 in the USA have wreaked intense anxiety and apprehension among the general population and the healthcare professionals who are tasked with the care and well-being of their patients. Health care professionals often have limited availability of essential personal protective equipment resources, and few reliable or time-proven treatments and protocols readily available. As the COVID-19 pandemic rapidly approaches the one-year mark, lockdowns and travel restrictions continue, reports of domestic abuse and other human failures are reportedly on the rise in the general population, and cases of posttraumatic stress related disorders are increasing within the healthcare professionals workforce, particularly among the more junior and less experienced members of the medical staff. Thus, these observations indicate a need for increasing emphasis on pre-stress and preventive post traumatic stress disorder training and teamwork education and support at all levels of medical education involving patient care, including first responders, nursing, allied healthcare professionals, and medical student and residency training. Historically pandemics have occurred about three times each century, so the time to address the situation is now critically close at hand; not only is it essential to enhance the preparedness of our current medical workforce, but it is also the time to begin preparing for the next generation of healthcare professionals such that the next generation of healthcare professionals may have a grasp on the next pandemic in advance of its appearance. SARS-CoV-2 and most recent offspring in the USA, the B.1.1.7 variant (SARS-CoV-2 VUI 202012/01) arrived without warning: this is not a dress rehearsal and is likely here to stay at least until a vaccine and/or herd immunity becomes effective in the population. While the morbidity and mortality of SARS-CoV-2 VUI 202012/01 is predicted to be of similar magnitude to that of its parent virus at around 0.14%, the variant mutation is believed to be more highly contagious than SARS-CoV-2 and may be responsible at least in part for the recent spike in positive cases in the US, UK and elsewhere. Introduction of additional stress prevention training such as facial recognition signs among co-workers may hold the cue to address this concern and reduce the incidence of stress-related morbidity among medical staff. Now as never before, an ounce of prevention in the way of pre-stress and environmental stress preparedness may be worth a pound of cure.

Effect of physical and physiological parameters on the performance of sub-elite Indian upper order batsmen in T20 matches: a pilot study
Authors: Biswas Subhashis , Bhattacharya Rupayan
Published: November 2022

Scanty studies on physiological demands and movement characteristics to predict batting performance in comparative T20 cricket matches seem to be a fetus of seeds yet to be explored. A pilot study was carried out to explore the relationship between physical and physiological responses with the batting performance of sub elite T20 upper order batsmen and also the effect of batting innings on their performance. Twenty male batsmen who represented at district level (age: 20.0±2.4years, height: 1.68±0.58m, body mass: 63.6±7.6kg) and played in the upper order (1-4) were purposely selected and alienated according to batting innings. Key performance indicators of batting indicate that an individual score is significantly correlated (p=<0.001) with running between the wickets. The study revealed a significant correlation (p=0.02) between the individual score and average heart rate. Also, an ‘inverted U’ shaped trend line was observed between the individual score (y) and the average heart rate (x) (y = -0.09x2 + 1.38x + 7.27 with R² = 0.33). The moderate to high heart rate (126-157 bpm) zone was found to be effective for scoring at least 30 runs. Batting innings had no significant influence on upper-order batsmen's physical, physiological, and batting performance metrics. During batting, most of the time was spent while standing, most of the distance was covered by walking, and average heart rate of the batsmen was in the moderate to high-intensity zone.
Mental health in the injured athlete–why the spikes protocol matters
Authors: M Ryan Patrick
Published: November 2022

Athletes are a unique subset of patients that pose unique challenges to the treating physician. The mental health of injured athletes is becoming increasingly recognized as a vital part of adequate care of these patients. Numerous studies link poor mental health function and pre-existing mental health diagnoses to poor outcomes including delayed return to play, inability to return to play, risk of re-injury, and exacerbation of underlying mental health problems. Because this is a topic not often studied by team physicians and this manuscript aims to provide a practical tool to help these physicians communicate with injured athletes. The SPIKES protocol is an effective way to acknowledge and adequately communicate with this unique patient population.
Bone health risk assessment in a clinical setting: an evaluation of a new screening tool for active populations
Authors: Keay Nicola , Francis Gavin , Hind Karen
Published: November 2022

Introduction: Risk factors for poor bone health are not restricted to older, sedentary populations for whom current screening is focused. Furthermore, access to dual X-ray absorptiometry scanning can be limited in clinical practice. The purpose of the current study was to develop a bone health-screening tool suitable for inclusion of both younger and active populations, combined with assessing bone health with radiofrequency echographic multi spectrometry technology (REMS). Methodology: Participants (n=88) attending a physiotherapy clinic in the UK was recruited to the study: 71 women (mean age 41.5 SD 14.0 years); 17 men (mean age 40.2 SD 14.9 years). Participants completed an online bone health-screening questionnaire developed specifically for this study covering a range of lifestyle, physiological factors, combined with medical interview and received bone mineral density (BMD) measurement at the lumbar spine and femoral neck using REMS. Results: Scoring of the bone health-screening questionnaire produced a distribution of bone health scores, with lower scores suggesting a higher risk for poor bone health. In women, scores ranged from -10 to +12, mean score 2.2 (SD 4.8). In men, scores ranged from 0 to 12, mean score 6.9 (SD 3.2). A positive correlation was observed between the bone health score derived from the questionnaire and lumbar spine and femoral neck BMD Z-scores (p<0.01). Conclusions: This new and comprehensive bone health-screening questionnaire with interview was effective in identifying active individuals at risk of bone fragility, who might be missed by current screening methods. The use of REMS technology to measure bone health was feasible in the clinical setting.

Investigating the Method of Da’wah and the Role of Political-Economy of Jemaah Tarbiyah in Urban Malang Society
Authors: A'isyah A'isyah , Lessy Zulkipli
Published: November 2022

Since the emergence of the overwhelming electoral vote for Partai Keadilan Sejahtera (Prosperous Justice Party) in the 2019 legislative election in Malang City, we discovered the impact of political-economy of Jemaah Tarbiyah on the urban society is a significant boost in electability for PKS. The subject selected is an Islamic philanthropic organisation, Ash-Shahwah Foundation (YASA) in Malang City as the sympathisers of Jemaah Tarbiyah. The supportive factors for regulating the political economy of Jemaah Tarbiyah include the method, role, and participation of YASA in Malang City. Through the method of da’wah, the figure of Jemaah Tarbiyah, Abu Haidar, stated that shalat is the key to success in life, and this has been successfully gaining hundreds of members. The role of YASA is to educate the urban society that obligatory alms become a lifestyle for their charitable politics. YASA becomes an intermediary to the connection of elite-mass or mustahiq-cadres’ relationships for gaining trust and getting massive electoral votes. The urban society participation, particularly the benefactors, can be seen from their enthusiasm in donating their wealth and demonstrating solidarity among individuals to strengthen informal religious learning courses in mosques. Findings show that the political economy of Jemaah Tarbiyah initiated the great success of gaining substantial electoral votes through philanthropic practices used as indirect support and funding for election campaigns. Notably, there is a political tendency for YASA to change its paradigm of philanthropic practice, for which the initial goal was to raise humanitarian aid and charitable funds and to shift funds toward financing a campaign.

Five essential keys visible reflections of Islamic brands narrate the form of a brand that identifies with Islamic characteristics. This research is expected to help provide input or reference for further research and considerations in building an Islamic brand.
Xenophobia in South Africa: Alignment of policy-making with the aim of the Missio Dei (Mission of God)
Authors: Thinane Jonas Sello
Published: November 2022

Generally, the problem of xenophobia remains a complex and challenging topic for most countries of the world, for Africans and South Africans in particular. Constructed upon existing literature, this paper contributes to the discourse on anti-immigrant or xenophobic feelings in South Africa. This paper uses Missio Politica as a missiological framework combined with political theology to examine xenophobia. Although alluring further extensive research, it represents the neglected step in organising the vast body of missiological perspectives on the subject of xenophobia regarding the objective of the Missio Dei. It is entirely devoted to seeking answers to the question of xenophobia by appealing to the correct understanding of Missio Dei’s goal as demonstrated in the account of Noah's Ark in Genesis 6-9. Consequently, it concludes that to circumvent xenophobic incidents, African countries must first prioritise salvation for their local citizens, just as Noah did with his own family, before attempting to invite the entire continent into the tiny ark of salvation. Correspondingly, it concludes that South African policy-makers should familiarise themselves with important religious ideologies of their constituencies to shape public policies that are compatible with societal religious aspirations. Xenophobia has become an issue of great concern, particularly in South Africa. In the discipline of missiology, the current literature does not provide a clear methodology for solving xenophobia. This study represents the first missio politica analysis of the impact of xenophobia on the goal of Missio Dei.

Published: November 2022

This article is focused on analising the religious character of the Malays in the 19th century in the Syair Burung manuscripts. It was one of the cultural relics of the Malay community in the past that can provide useful information for the religious life of today's society. This paper was based on library research with a qualitative method approach that leads to content analysis, while the primary source is the text edition of Syair Burung manuscript. The results of the analysis found that Syair Burung is a symbolic poem that uses various birds for the storyteller. This is because the Malay people were colonised by the British, thus, they did not dare to write the truth. Likewise, regarding the religious life that occurs in society, the author is only able to change the character of the story. This research found the religious character of the Malays in the 19th century was divided into a three-character group. First, a group that understands religious teachings and was obedient in practicing them, was symbolised by 13 species of birds. Second, a group that comprehends religious teachings but does not practice them, which is symbolised by 8 types of birds. Third, the group does not understand religious teachings and also does not practice them, which is symbolised by 9 types of birds.
The Participation of Religious Organisations and Their Contributions to the Countermeasure of HIV/AIDS in Indonesia
Authors: Junaidah Junaidah , Bakti Andi Faisal
Published: November 2022

Several works available on religion and HIV/AIDS indicated that several religious groups in the world, including Indonesia, are still reluctant to be involved in the prevention of HIV/AIDS. However, the involvement of the two largest religious organisations in Indonesia, Nahdlatul Ulama (NU) and Moluccas Protestant Church (Gereja Protestan Maluku/GPM) in combating HIV/AIDS for the last ten years deserve to be investigated and studied, as new evidence which refutes the above studies. The result of this study shows, first, the involvement of NU and GPM in the prevention of HIV/AIDS showed the potential of religious organisations in health development, particularly as a progressive strength in the fight against pandemics such as HIV/AIDS. Second, the most fundamental forms of involvement are changing religious views about HIV/AIDS as a cursed disease into a disaster or a test that requires patience. NU and GPM also organise social activities, public education, and policy advocacy for HIV/AIDS programs. Third, although this article has not been able to present the decrease of HIV/AIDS prevalence in Indonesia as a result of religious organisations involvement such as NU and GPM, however, at least there have been some contributions from both organisations toward the decrease of negative stigmatisation to people living with HIV/AIDS.
Enrichment of dark chocolate with free and microencapsulated white tea and jujube extracts: Impacts on antioxidant, physicochemical, and textural properties
Authors: Shahbazi Somayeh , Didar Zohreh , Vazifedoost Mohsen , Naji-Tabasi Sara
Published: November 2022

In this study, dark chocolate was enriched with white tea (WT) and jujube extracts in form of free extract and microcapsules. Each form of two extracts was added to dark chocolate in concentrations of 1, 3, 5, and 7% w/w. The microcapsules were produced using pectin/casein (10% w/w), and their particle size distribution (PSD) and Fourier transform infrared spectroscopic analysis were performed. Phenolic content, antioxidant activity, pH, moisture content, color parameters and texture of enriched dark chocolates were measured. As expected, addition of extracts caused a significant increase in total phenolic content and antioxidant properties of dark chocolates compared to the control sample (no extract added) in both free and microencapsulated forms, with a stronger effect of WT extract than jujube extract.
Fungal bioconversion of brewery by-products
Authors: Boukid Fatma , Pera Joan , Parladé Javier , Castellari Massimo
Published: November 2022

Waste management of brewery by-products is economically and environmentally problematic. In the frame of bio-recycling, this study aims to investigate the bioconversion of brewery by-products by filamentous fungi. Pleurotus ostreatus and Lentinula edodes were grown on different substrates based on brewer’s spent grains (fresh and dry). Afterwards, fatty acids and sterols were determined. Following the selection of the suitable substrate composition for fungal growth, results showed that fatty acids composition of fungal biomasses varied significantly as a function of substrate and fungal strain. Interestingly, fungal fat might be used for human nutrition due to low SFA/UFA ratios (~0.2–0.4) within the same range of vegetal oils. Sterols profile of fungi biomass revealed the predominance of ergosterol. Also, it was found that the fungi growing on by-products slightly reduced the cholesterol contents. As such, this approach focusing on the bioconversion of by-products using fungi can provide biomasses with a fat composition suitable for feed and human consumption.
Annual World Bioprotection Summit and Awards, Birmingham, UK, May 2022
Authors: Blake Robin
Published: November 2022

The Annual World BioProtection Summit and Awards saw over 100 people return in a face-to-face capacity for the first time in three years on 23–24 May 2022 at the NEC in Birmingham, UK. Dr Sarah Harding, Communications Director at the World BioProtection Forum (WBF), welcomed participants
and briefly explained the remit and recent achievements of the WBF, one of the organisers of the event. The WBF is a non-profit organisation founded by Dr Minshad Ansari in 2019 to connect the biocontrol industry and encourage collaboration between industry and academia, with the aim of connecting
different stakeholders who can work together to ensure the successful development and commercialisation of biocontrol products. Achievements so far include the recruitment of more than 20 advisors, in addition to the board of directors, to help drive the organisation forwards, successful events,
establishment of the Awards programme to cover the scope of biological in agriculture and a regulatory reform campaign started in 2021. Dr Harding finished her introduction by thanking the premium sponsors Bionema, gold sponsors Oro Agri, and other sponsors and exhibitors including AEH Innovative
Hydrogel, Agri-TechE, AHDB, APIS, Dejex, Evonik, Fera, Koppert, Mathys & Squire, Medinbio, NPP, Sribio, UKRI, Valent BioSciences and Vigna Brasil. The event was officially opened by Dr Ansari, Founder & Chairman of the WBF, and CEO and Founder of Bionema Limited, who posed the question
"Can two days change the trajectory of the biocontrol industry?" Dr Ansari said how delighted he was to see 18 countries represented at the event. The world continues to face unprecedented demands on food security with over $500 billion crop damage caused by pests and diseases annually,
and whilst $80 billion is spent on chemical pesticides annually, concerns over the impacts on human health and the environment, especially in the EU is helping drive change such as the proposed 50% reduction in the use of chemical pesticides by 2030 and corresponding desire to increase
the land under organic farming. Whilst the WBF is working to drive change, the biocontrol industry in the UK/EU continues to face challenges such as the long and costly regulatory process, higher unit price and limited products in the market slowing the adoption of biopesticides and continued
concerns over variable efficacy. The conference was closed by Dr Ansari who thanked the speakers, sponsors and audience for their participation and attendance. He praised the excellent quality of the talks and thanked key individuals who helped put the event together. The take home message
is that this event can be considered as a single conference, one-stop shop, including investor pitches, to connect the biocontrol industry and allow for successful commercialisation.

Interview with Shay Shaanan, STK Bio-Ag Technologies
Authors: Blake Robin , Shaanan Shay
Published: November 2022

STK was previously known as Stockton. It was started in 1994 by Peter Tirosh who left a 23-year career at Makhteshim-Agan (now ADAMA) to set up his own generic company buying solutions from China and selling them into Latin America where he had good connections from his previous jobs.
In 2004, Peter met two people from an Israeli start-up who told him about an idea to take tea-tree oil (TTO) from Pharma where it was used as an anti-bacterial agent and develop it into a solution for crop protection. Peter cooperated with them and after two years acquired the company. With
money from Stockton they investigated TTO in more detail, worked out which diseases it controlled, how to formulate and use it, and in 2012, discovered that TTO controlled black Sigatoka (Mycosphaerella fijiensis), a key disease in LATAM bananas at the time. In 2015 there was a change
in company ownership when a new CEO was appointed from outside the family. Following a $90 million investment from a public Chinese company, a new strategy was implemented in 2016 to develop and market botanical crop solutions for sustainable agriculture and aquaculture, and a rebranding
in 2018 changed the company name from Stockton to STK to reflect the company's transition from its legacy generic agrochemicals business to its new focus on bio-ag technology and botanical-based solutions. The biofungicide Timorex Gold is its flagship product and based on TTO derived from
the Melaleuca alternifolia plant. It is a broad spectrum biofungicide with preventive and curative properties recommended for the control of many important plant fungal and bacterial diseases in a wide range of fruit and vegetable crops. It can be used in rotations with other products,
in tank mixes and as a solo formulation. The TTO extract contains over 100 compounds, some of which work synergistically and some which offer diverse modes of action.

Published: November 2022

Аналітично досліджується нагрівання щільного шару сипких (гранульованих) матеріалів у мікро­хвильовому полі. Представлено математичну модель процесу сушіння у вигляді диференціальних рівнянь переносу стосовно необмеженої пластини. Модель враховує ослаблення впливу внутрішніх джерел у процесі сушіння за рахунок зміни діелектричних характеристик вологого матеріалу. Враховується, що втрата вологи у матеріалі підпорядковується експоненційному закону. Розглянуто фізичний сенс складових рівнянь перенесення теплоти та маси. Описано процедуру отримання розрахункових залежностей для визначення середньої температури та вмісту вологості шару за граничних умов третього роду (тепловіддача на границі). Отримані залежності дають можливість розраховувати значення вмісту вологи і температури матеріалу при мікрохвильовому нагріванні. Проведена апробація математичної моделі сушіння щільного шару сипкого матеріалу при різних значеннях коефіцієнта тепловіддачі і питомої потужності мікрохвильового поля. Наведено результати зіставлення розрахункових даних з результатами експериментів, які демонструють зміну температури та вмісту вологи в часі. Показано, що розрахункові та експериментальні дані задовільно сходяться. Зазначається, що експериментальні криві свідчать про наявність автоколивального процесу зміни температури при сушінні, що пояснюється дифузійним опором матеріалу виходу вологи. Сумісність експериментальних та розрахункових результатів свідчить про відповідність математичної моделі реальним процесам перенесення теплоти та вологи при нагріванні шару матеріалу в мікрохвильовому полі. Апробація аналітичних залежностей для середньої температури шару та вологовмісту дозволяє стверджувати, що їх можна реко­мендувати для оцінки технологічних параметрів процесів перенесення теплоти та вологи при нагріванні шару матеріалу в мікрохвильовому полі

Зараз використовується метод перетворення рідини на перегріту пару, який має багато не-доліків. Головними з них є необхідність попереднього нагрівання великої маси рідини при введенні установки в дію і ізобарний процес пароутворення. Початкова теплота нагрівання рідини втрачається при виведенні установки з експлуатації, а використання ізобарного процесу перетворення рідини в пару вимагає більше теплоти, ніж ізохорний. В ізобарному процесі має місце непродуктивне розширення пари у процесі її утворення в порівнянні з ізохорним процесом. Пропонований гідродинамічний спосіб перетворення рідини на перегріту пару передбачає одноразовий перехід у пару невеликої кількості рідини та використання ізохорного процесу її перегріву. В цьому способі дискретна кількість рідини, попередньо стиснутої та ізобарно нагрітої до стану насичення, розпорошується на вертикально розташовану поверхню, температура якої вища за температуру рідини. Кипляча рідина, розпорошена тонким шаром на такій поверхні, миттєво перетворюєтьсяв насичену пару. Поверхня, що постійно нагрівається гарячим джерелом теплоти, поміщена в замкнутий об'єм, обладнаний автоматичними клапанами. Клапани регулюють момент та кількість рідини, що впорскується, та кінцевий тиск (температуру) перегріву пари. Працездатність та ефективність запропонованого методу пароутворення та перегріву пари перевірена на прикладі термодинамічного циклу утилізаційної паротурбінної установки (УПТУ), гарячим джерелом теплоти якої є відпрацьовані гази двигуна SDR-8 фірми «Зульцер» потужністю Ne = 1250 кВт, температура яких 350 ºС. При наявності холодного джерела теплоти з температурою 30 ºС теоретична потужність такої УПТУ дорівнює228 кВт. Потужність аналогічної установки, що працює за класичним циклом Ренкіна в тому самому інтервалі температур, – 221 кВт, тобто менше на 3 %. Так само вище виявляється термічний ККД установки з гідро-динамічним способом пароутворення. Переваги запропонованого способу пароутворення над статичним, що використовується зараз, – очевидні. Відсутній великогабаритний, масивний та конструктивно-складний паровий котел. Використовується більш ефективний із термодинамічної точки зору ізохорний процес перегріву пари. Наявна велика маневреність як при проектуванні, так і при експлуатації паротурбінних установок з гідродинамічним способом перетворення рідини в перегріту пару
Системи регулювання рівня рідких кріопродуктів в дефлегматорах для збагачення неоногелієвої суміші

Published: November 2022

Враховуючи дефіцит неону та віддаленість джерел газової сировини, актуальним стає розгортання апаратів для збагачення концентрату у місцях його отримання. У статті розглянуто тех­нічні рішення, спрямовані на автоматизацію установок для збагачення неоногелієвої суміші шляхом конденсації N2 в окремому апараті – дефлегматорі, який охолоджується рідким азотом. Конденсаційне збагачення потоку досягається за рахунок виділення азоту при тиску 0,6...1,2 МПа і температурах 68...78 К. Найпростішим регулятором рівня рідкого холодоагенту і азотного конденсату є клапан, механічно пов'язаний з поплавком в азотній ванні. Поплавкові клапани – єдині рухомі вузли дефлегматора. Порушення їх працездатності загрожує втратами холодоагенту, продукційної суміші та позаштатними ситуаціями. При виборі конструкції поплавкових регуляторів слід враховувати особливості об'єкта управління та режимні параметри дефлегматора. У роботі наведені приклади різного виконання поплавкового клапана, кожен з яких має свої переваги і недоліки. Як приклад, були розглянуті поплавки з металевим герметичним корпусом. При виборі геометричних розмірів герметичного поплавка необхідно враховувати підйомну силу та властивості міцності, особливо для клапана в збірці конденсату. Отримано залежність допустимого рівня тиску і запасу плавучості від геометричних характеристик. Проведений аналіз дозволяє спростити вибір розмірів поплавка в інтервалі розташовуваного сортаменту сферичних днищ. Обґрунтовано переваги електромагнітних клапанів рівня, перехід до яких дозволяє знизити теплоприпливи, підвищити надійність, ремонтоспроможність, а також допускає можливість дистанційного контролю. Показаний приклад управління автоматичними клапанами у вигляді блок-схеми. Показані для порівняння варіанти виконання дефлегматора з поплавковими та електромеханічними регуляторами

This paper presents an energy analysis of the marine refrigeration system as a component of the machi­nery system of the cruise liner “Scalet Lady”. This type of ship is one of the most complex types from an energy point of view, which is associated with a wide variety of energy consumers. The study uses two methods of thermodynamic analysis of real cycles: the method of cycles and entropy-statistical method. For the analysis, the experimental data on the operating modes of the marine refrigeration system has been used. According to the results of processing the experimental data, a thermodynamic cycle has been formed and an energy calculation of the cycle has been performed using classical methods for two-stage refrigeration machines. With the help of the cycle model, the external irreversibility is determined by successively reducing the energy efficiency of the ideal cycle. The Lorentz cycle has been chosen as an ideal model, taking into account the variable temperatures of heat supply and removal during heat exchange “heat source – phase transformations of the refrigerant R407f”. Along with the evaluation of efficiency, the distribution of losses by the components of the refrigeration system has been established, energy weaknesses that require improvement has been identified, and the most effective ways to reduce energy costs have been outlined. Analytical conclusions have a graphical interpretation of the thermodynamic efficiency assessment for the real refrigeration cycle. It has been established that in the considered real cycle of a marine refrige­ration system, the greatest influence on energy efficiency is exerted by external irreversibility in the condenser, in particular, in the overheating zone (25.64% of the total energy consumption of the plant). The effect of irreversibility in the compressor is not fixed
Perception of emotion and postural stability control at different distances
Authors: Chikh Soufien , Charrada Salma , Watelain Eric
Published: November 2022

The effect of emotion on postural control has been widely demonstrated in the literature. Postural control also depends on the distance that separates the subject from the observed stimulus. This work examines (i) the effect of distance on the perception of emotional stimuli and (ii) its effect on postural control. Sixty-eight women were asked to maintain orthostatic equilibrium under three emotional conditions (positive, negative, and neutral) at four distances (0.5 m, 2.1 m, 6 m, and 10 m). The findings showed that the perception of emotions was not influenced by distance but was influenced by valence and intensity, and that postural control was not influenced by emotional valence but by distance, with reduced oscillation amplitudes at 0.5 m distance. The perception of the image (valence and intensity) depended on the content, but not on the distance, and the presentation of emotional images tended to activate the defensive system, regardless of the emotional content. The center of pressure sway amplitude increased with an eye–object distance of up to 6 m (role of vision). The perception of the emotional effect was not linked to the distance effect on the postural control of women in static positions.
Localized deformation at initial stages of plastic flow in high-manganese steel
Authors: Barannikova S. A.
Published: November 2022

The work is devoted to the study of macroscopic localization of plastic deformation during uniaxial tension of single crystals of the Hadfield steel (Fe – 13 % Mn – 1.03 % C). In the course of studies at the stage of easy sliding, significant differences were found in the nature of macrolocalization of plastic deformation in the single-crystal samples under study. All patterns of deformation localization observed in these cases can be divided into two types. The first type of strain localization corresponds to the initiation at the upper yield point and further propagation of the strain front, which gradually transfers the sample material from undeformed state to deformed one. This manifested itself most clearly in single crystals oriented along the tension axis [377] and [355], where the strain localization pattern appears as a single zone of localized deformation on the yield plateau. Such a deformation front passes through the sample volume only once as a Chernov-Luders band. In this case, the flow of the material is carried out without hardening until all its elements are transferred to the deformed state. Single zones of strain localization were also observed at the stages of easy sliding and yield plateau in the Hadfield steel single crystals oriented along the tension axis [123] and [012]. In the second type of localization, at the stage of easy sliding, synchronous movement along the pattern of several deformation centers occurs. Their movement can be unidirectional and counter, and the speeds are both the same and different from each other. Further deformation of the Hadfield steel single crystals oriented along the tension axis [355] or [012], led to the movement of two deformation localization centers at the stages of easy sliding. In single crystals oriented along [111], the strain localization pattern is respectively represented as four localized strain sites. Consequently, the synchronous movement of deformation fronts occurs along an already deformed, albeit to a small extent, material. As a reason for the difference between the two types of macrostrain localization at stage I (the easy sliding stage and the yield plateau), the number of active sliding systems or tensile twinning in the studied single crystals can be discussed based on crystallographic analysis and metallographic studies.
