Importance: The article addresses unicorn companies as the most successful and fastest-growing start-ups. It analyzes to what extent their capitalization is justified, what prospects for growth they have after IPO, and how they meet investors expectations. Objectives: The objectives of the study include a comprehensive review of creation and development of unicorn companies, identifying the sources of their growth and credibility of their open market valuation. Methods: The study employs methods of analysis, synthesis, retrospective analysis, comparison, and compilation. Results: The paper shows why unicorns are overvalued in the market. It emphasizes that the possibility and expediency of unicorn capitalization depends on the interests pursued by market actors. The practicability of IPO and its implications also vary from company to company. Conclusions: and Relevance High capitalization of unicorn companies is not reasonably feasible in every instance: investors are often riding on the wave of a boom, after which the value of business falls to zero. However, high-tech and innovative unicorns, on the contrary, are drivers of development and their high capitalization is indeed justified.

Authors: Barral Valdez Christian
Published: December 2023

This study is focused on gauging the perception of hotel guests regarding global hospitality trends and verifying if global trends are significant factors in economic growth. It aims to measure if enhancing and adapting to global trends and shifts would provide economic upturn and specify recommendations on enhancing its capability to generate substantial revenues for the local economy. Further, the study gauged the interest of hotel guests in acquiring hospitality services through recent global trends and their perception of how it benefits the economy in general. A survey questionnaire was distributed among 399 hotel guests from thirty selected hotels and has been collated and analyzed. Through the survey, it has been discovered that there is a moderate, positive correlation between the global trends in the hospitality industry and its economic benefits, which conveys that the global trend in the hospitality industry has a moderate impact on economic advantages. It has also been found that the hospitality sector has effectively met the demands of leisure visitors and given them access to suitable workstation facilities. Furthermore, it has also been shown that the best predictor of hotel demand is the increase in Gross Domestic Product.

We have summarized, analyzed and assessed data on radiation accidents and incidents that occurred on the territory of the Russian Federation for the period from 2010 to 2022. The data are presented in the Data bank of radiation accidents and incidents of the Information and Analytical Center of Rospotrebnadzor on radiation safety, in the form of federal statistical observation No. 18 “Information on the sanitary condition of the subject of the Russian Federation”, and in radiation-hygienic passports of territories. The objective of the study was to conduct a comparative analysis of information on radiation accidents for the period from 2010 to 2022 contained in the above-mentioned sources. The objective of the study was to perform a comparative analysis of information on radiation accidents for the period from 2010 to 2022 contained in the above-mentioned sources. Comparison of the number of radiation accidents in dynamics has shown the presence of discrepancies between the studied data sources, lack of systematicity of these discrepancies, and multidirectional trends in the number of radiation accidents. From 2010 to 2022, in the Data bank of radiation accidents and incidents of the Information and Analytical Center of Rospotrebnadzor on radiation safety were registered 2,690 cases of radiation accidents in 71 subjects of the Russian Federation, in Forms No. 18 – 2,469 cases in 67 subjects, in radiation-hygienic passports of territories – 2,457 cases in 76 subjects. Differences in the structure of data provision have been established: in the data bank and Form No. 18 radiation accidents are classified, but at the same time the principles of classification coincide partially; there is no classification in the radiation-hygienic passport of territories. The analysis showed that no information on radiation accidents was received from four regions during the study period. Among the subjects that provided information, only six regions have coincidence of data on all sources. Some regions were identified where information was provided to some data bases but not to others. In five regions, a range of more than 50 cases was detected; the coefficient of variation in the number of radiation accidents between sources exceeded 33% in 53 subjects. The identified discrepancies demonstrate the lack of a systematic approach to the procedure for providing information on radiation accidents, which may be related to the failure to fully comply with the requirements for providing information to Rospotrebnadzor and the St. Petersburg Research Institute of Radiation Hygiene after Prof. P.V. Ramzaev, contradictions in the list of information to be provided in Rospotrebnadzor’s offices, and difficulties in determining by Rospotrebnadzor’s offices in the subjects of the Russian Federation what information is to be reported in this or that form of statistical observation.

Published: December 2023

The purpose of the study is to identify differences in the content of 137Cs in the phytomass of coastal aquatic vegetation of the Vetka and Chechersk districts of the Gomel region for the period 2012–2022. The description and identification of ecological groups of coastal aquatic vegetation and the sampling of soil and plants to determine the content of radiocesium in the growing seasons of 2012 and 2022 were carried out according to generally accepted methods. It was found that the content of 137Cs in water samples from the objects of Vetka district did not exceed the normative value for drinking water (10 Bq/kg). The average specific activity of radiocesium in the soil for the studied objects was 807±125 and 586±84 Bq/kg in 2012 and 2022, respectively; and for soil was 549±85 and 395±46 Bq/kg respectively. Over time, there was a decrease in the amount of radiocesium in soil and in ground by 1.3–1.4 times. The average content of the isotope in the plants in 2012 and 2022 was 93–917 and 59–578 Bq/kg, respectively. The amplitude of variation in the average values of accumulation coefficient in the soil-plant system was 1.03 and 0.11 Bq/kg:Bq/kg in 2012 and 2022, respectively. In the ground-plant system it was 3.08 and 0.01 Bq/kg:Bq/kg, respectively. The specific activity of 137Cs in the water of objects in the Chechersk region did not exceed 3 Bq/l. The average content of 137Cs in the ground was 316 and 231 Bq/kg in 2012 and 2022, respectively. The same parameters for the soil were within the limits of 471 and 340 Bq/kg, respectively. The average content of 137Cs in phytomass varied from 149 to 483 Bq/kg in 2012. After 10 years, the amount of radionuclide was 115–288 Bq/kg. The average values of accumulation coefficient in the soil-plant system in 2012 and 2022 were 1.44 and 1.01 Bq/kg:Bq/kg, and in the soil-plant system were 1.70 and 1.10 Bq/kg:Bq/kg, respectively. As a result of the study, similar dominant groups of coastal aquatic plants were not identified in terms of the accumulation of radiocesium in the objects of the Vetka and Chechersk regions.

Published: December 2023

Official data on radiation doses for flaw detectors do not take into account working conditions. In the reporting forms, there is no division between personnel performing flaw detection in stationary conditions and in situ, which roughly averages the values of effective doses towards underestimating the values for personnel working in site radiography. In this work, comparison of our own data on radiation doses of flaw detectors was performed. It has been shown that the difference in the mean and median values of effective doses reaches 10 times. When performing flaw detection in stationary conditions, the personnel are at a sufficient distance from the source of ionizing radiation and are well shielded by engineering protective equipment, so the exposure is fairly uniform. In such cases, one individual thermoluminescent dosimeter located at chest level is sufficient to estimate the effective dose. The average annual effective dose for personnel conducting flaw detection in stationary conditions is 0.87 mSv (median – 0.88 mSv, maximum value – 0.99 mSv). During individual radiation monitoring of personnel performing flaw detection in situ using portable roentgen flaw detectors, cases of neglect in the use of individual dosimeters were identified, which requires more stringent measures to comply with existing requirements for ensuring radiation safety and operating rules for individual dosimeters. The average annual effective dose for flaw detectors working with portable roentgen flaw detectors is 9.03 mSv (median – 8.85 mSv, maximum value – 12.37 mSv).
O Teste da Proporcionalidade no Tribunal Constitucional do Peru e no Supremo Tribunal Federal
Authors: Gavião Filho Anizio Pires , Guidolin Renata Vielmo
Published: December 2023

A presente investigação tem por finalidade examinar a aplicação do teste da proporcionalidade pelo Tribunal Constitucional do Peru e pelo Supremo Tribunal Federal. A questão a ser respondida é a seguinte: Como o Tribunal Constitucional do Peru e o Supremo Tribunal Federal aplicam o teste da proporcionalidade? O teste da proporcionalidade é uma ferramenta central da jurisdição do Estado de direito constitucional democrático. Em uma constituição com catálogo de direitos fundamentais somente são admitidas restrições justificadas com base no teste da proporcionalidade. O problema da aplicação do teste da proporcionalidade é central, justificando-se examinar como os tribunais constitucionais empregam essa ferramenta metodológica. A análise de decisões do Tribunal Constitucional do Peru mostra a aplicação do modelo standard, amplamente difundido, configurado nos subtestes da legitimidade do fim, da adequação, da necessidade e proporcionalidade em sentido estrito. A análise de decisões do Supremo Tribunal Federal evidencia a prevalência de aplicação indistinta e não rigorosa de uma ideia geral e ampla de proporcionalidade, mais como um topoi retórico-argumentativo, identificada com razoabilidade ou ponderação. Em algumas decisões, pode ser rastreada a aplicação do teste da proporcionalidade na configuração do modelo standard. Comparativamente, as decisões do Tribunal Constitucional do Peru são superiores às do Supremo Tribunal Federal em relação à qualidade da fundamentação da aplicação do teste da proporcionalidade. A pesquisa é bibliográfica, com análise de casos comparativa, e o método é o hipotético-dedutivo.
The dynamic interplay of root exudates and rhizosphere microbiome
Authors: YETGİN Ali
Published: December 2023

The rhizosphere microbiome plays a vital role in plant growth, health, and nutrient acquisition. One of the key factors that shape the composition and function of the rhizosphere microbiome is root exudates, the complex mixture of organic compounds released by plant roots. Root exudates serve as a source of energy and nutrients for the rhizosphere microbiome, as well as a means of communication between plants and microbes. The dynamic interplay between root exudates and rhizosphere microbiome is a complex and highly regulated process that involves multiple feedback loops and interactions. Recent studies have revealed that the composition and quantity of root exudates are modulated by a range of biotic and abiotic factors, including plant genotype, soil type, nutrient availability, and microbial community structure. In turn, the rhizosphere microbiome can influence the production and composition of root exudates, through processes such as nutrient cycling, plant hormone synthesis, and modulation of plant defense responses. Understanding the dynamics of root exudates and rhizosphere microbiomes is crucial for developing effective strategies for microbiome engineering, plant-microbe symbiosis, and sustainable agriculture. This review provides an overview of the current state of knowledge on the dynamic interplay between root exudates and rhizosphere microbiomes, highlighting the key factors and mechanisms that govern this complex relationship.
Identifying the pathways of extreme rainfall in South Africa using storm trajectory analysis and unsupervised machine learning techniques

Published: December 2023

This study has utilised National Oceanic and Atmospheric Administration (NOAA) NCEP/NCAR Reanalysis 1 project meteorological data and the HYSPLIT model to extract the air parcel trajectories for selected historical extreme rainfall events in South Africa. The k-means unsupervised machine learning algorithm has been used to cluster the resulting trajectories, and from this, the spatial origin of moisture for each of the rainfall events has been determined. It has been demonstrated that rainfall events on the east coast with moisture originating from the Indian Ocean have distinctly larger average maximum daily rainfall magnitudes (279 mm) compared to those that occur on the west coast with Atlantic Ocean influences (149 mm) and those events occurring in the central plateau (150 mm) where moisture has been continentally recirculated. Further, this study has suggested new metrics by which the HYSPLIT trajectories may be assessed and demonstrated the applicability of trajectory clustering in a region not previously studied. This insight may in future facilitate improved early warning systems based on monitoring of atmospheric systems, and an understanding of rainfall magnitudes and origins can be used to improve the prediction of design floods for infrastructure design.
A socio-ecological evaluation of the conservation efforts in the Nevado de Toluca protected area, Mexico: Governmental performance and local community perception from a rural context
Authors: Caro Borrero Angela Piedad , Rivera Ramírez Karla Isabel , Carmona Jiménez Javier
Published: December 2023

Protected Areas (PA) are the main conservation instrument in Latin America, but rural communities are rarely integrated into the decision-making. In Mexico, many conflicts related to PAs stem from guaranteeing equitable access to resources for local communities against private economic interests. The aim of this manuscript is to present a strategy to evaluate the functioning of the PA from a socio-ecological perspective, including: diagnosis, evaluation of the conservation instrument, and intervention proposal. The results show that the Nevado de Toluca PA was recategorized without adequate characterization of the problems facing its conservation. The impact has been biased towards the development of large-scale activities while local communities have been excluded. This scenario has resulted in a migration of local men to cities in search of work, while women and children face unequal management of natural resources. In terms of aquatic ecological quality, indicators show signs of degradation that have not been improved through the management plan. The activities proposed in the annual operational plans are unrealistic since they include no support and training. We propose participatory monitoring as a strategy for community empowerment in the use of water resources, as well as a cohesive element that reconciles government policies and local needs.

Marine fungi communities play a crucial role in the recycling of nutrients, restoration of biological systems, and the overall functioning of ecosystems. While aquatic fungal communities do react to pollution, there is a significant lack of information regarding the changes in the fungal community's structure, caused by marine pollution. In this study, we aim to address this gap in knowledge by investigating the range and makeup of fungal species present in marine environments in a polluted bay in Tunisia, spanning a biodiversity hotspot (Monastir Bay). Sequence analysis of the internal transcribed spacer region from culturable mycobiome and physicochemical parameters were investigated at seven sites in the bay. A total of 32 fungal taxa were identified at the genus and/or species levels and were assigned to four major groups (Aspergillacae 37.5%, Dothiomyceta 21.87%, Sordariamyceta 28.12%, and Yeasts 12.5%) with a remarkable predominance of Aspergillus genus. Assessment of the Shannon–Wiener diversity index and the Simpson dominance index revealed that the highest species diversity index (0.84) was recorded at the Kheniss site. Our results suggest the existence of diverse fungal communities, can be considered a useful community model for further ecological and evolutionary study of fungi in the bay.

Published: December 2023

Though concrete is one of the most widely used construction materials, there are some concerns and shortcomings associated with it. Cementitious materials' quasi-brittle behavior, which leads to cracking and a loss of durability, is a major concern in structural applications. In this review, the latest research on reinforcing cementitious concrete with carbon nanotubes (CNTs) is reviewed, with an emphasis on the material's structural performance in building and a comparison of CNTs to other reinforcing fibers. The improvement of the macro mechanical properties of carbon nanotube-reinforced composite structures has been discussed in the form of functionally graded carbon nanotubes reinforced composites (FG-CNTRC). Several researches have, in the past, used other forms of reinforcements to enhance the properties of concrete till the implementation of nanotechnology in concrete production by incorporating CNTs into the concrete mixes. Concrete's crucial mechanical properties as a structural material and the durability of conventional cement-based building materials can both be improved by CNTs. They have drawn a lot of interest because they are an engineering material with a wide range of uses. The creation and characterization of cement-based materials reinforced with CNTs have been studied by researchers. Comparisons between the effects of CNT and other fibers on concrete have also been made. This concrete reinforcement type's environmental impact and sustainability have also been discussed. According to studies, CNT can greatly enhance the performance of cement-based materials.

Os objetivos desta pesquisa foram identificar, caracterizar e valorar os geossítios presentes no Baixo Vale da Bacia Hidrográfica do rio Piracuruca, norte do estado do Piauí. O estudo teve carater descritivo, quanto ao seu objetivo, e empregou levantamento bibliográfico e cartográfico. Essas etapas iniciais foram essenciais para, posteriormente, permitir a mensuração do Valor Turístico (Vtur) dos geossítios mapeados, a partir de um grupo de cinco variáveis. Por meio do estudo foi possível mensurar o Valor Turístico (Vtur) para oito geossítios, situados no Baixo Vale da Sub-bacia do rio Piracuruca. Devido à atuação do tempo esses geossítios apresentam marcas de processos erosivos que promoveram o surgimento de relevo de aspecto ruiniforme, feições de dissolução (marmitas e bacias), pináculos, placas poligonais, fraturas e descamação. O Vtur exibiu valores muito baixos para os parâmetros utilizados, fruto da ausência de infraestrutura para visitação e mecanismos de controle. As informações apresentadas devem subsidiar a tomada de decisões no sentido de elaborar mecanismos para viabilizar o uso geoturístico, considerando um rigoroso planejamento para a geoconservação dos geossístios identificados.

Celem artykułu jest przedstawienie oryginalnej japońskiej subkultury młodzieżowej otaku związanej początkowo ze światem młodych chłopców oraz kultury kawaii przez badaczy społecznych wskazujących na jej związki z młodymi dziewczętami. Współczesna kultura kawaii jest obecna w japońskiej estetyce i kulturze popularnej od wielu lat, wspierana przez rządowy program „Cool Japan”. W opinii zarówno psychologów, jak i socjologów, urocze i słodkie kawaii, widoczne w reklamach, filmach animowanych, komiksach (mangach), zabawkach, modzie ulicznej, muzyce, a nawet specyficznym sposobie mówienia, powoduje proces infantylizacji młodzieży. Pojawia się kolejne pokolenie, które obawia się wejść w dorosłość. Kultura kawaii została poddana próbie interpretacji z wykorzystaniem metod antropologii wizualnej, przez niektórych autorów definiowanej jako etnografia wizualna.

Published: December 2023

Physical activity (PA) after a colorectal cancer (CRC) diagnosis can improve physical function and quality of life and is associated with decreased mortality rates and longer disease-free survival. The accelerated use of videoconference technology during and following the COVID-19 pandemic offers an opportunity to explore the potential of a virtually supervised intervention to help survivors of CRC increase PA. A two-arm single blind pilot randomized controlled trial of individuals who had completed treatment for CRC within the previous five-years (NCT03781154, 12/19/2018). The 12-week intervention consisted of circuit-based, combined aerobic and resistance exercise, twice per week for approximately one-hour per session, and five social cognitive theory-based PA behavior change discussion sessions. All intervention components were delivered in real-time via Zoom. Feasibility and acceptability were assessed, and the effects of the intervention were explored for the outcomes of PA (activPAL™ accelerometers and self-report), social cognitive theory constructs (barriers self-efficacy and outcome expectations), and physical fitness (submaximal aerobic capacity, upper and lower body muscular strength and endurance). Twenty-nine eligible individuals (55.2% women, Mean = 61 ± 11 years old, Mean = 22.0 ± 15.1 months since diagnosis) were randomized to the videoconference PA intervention (n = 15) or a PA education control (n = 14). A total of N = 25 completed the study for a retention rate of 86.7% in the intervention arm and 85.7% in the control. Adherence to intervention components was >86%. The intervention was highly acceptable with ≥90% responding “yes” or “definitely yes” that they enjoyed participating. Trends suggested that intervention participants had greater improvements in accelerometer measured steps per day, daily minutes of light PA, sedentary time, and aerobic fitness. There was no change in social cognitive theory constructs, and muscular strength and endurance improved in both the intervention and control. A 12-week videoconference PA intervention was feasible and acceptable among survivors of CRC, and the greatest magnitude of difference for intervention effects was observed for light PA and sedentary time. A fully powered trial is needed to determine efficacy of the intervention for increasing PA and physical functioning.

Published: December 2023

Background

The COVID-19 pandemic prompted global behavioral restrictions, impacting public mental health. Sentiment analysis, a tool for assessing individual and public emotions from text data, gained importance amid the pandemic. This study focuses on Japan’s early public health interventions during COVID-19, utilizing sentiment analysis in infodemiology to gauge public sentiment on social media regarding these interventions.

Objective

This study aims to investigate shifts in public emotions and sentiments before and after the first state of emergency was declared in Japan. By analyzing both user-generated tweets and retweets, we aim to discern patterns in emotional responses during this critical period.

Methods

We conducted a day-by-day analysis of Twitter (now known as X) data using 4,894,009 tweets containing the keywords “corona,” “COVID-19,” and “new pneumonia” from March 23 to April 21, 2020, approximately 2 weeks before and after the first declaration of a state of emergency in Japan. We also processed tweet data into vectors for each word, employing the Fuzzy-C-Means (FCM) method, a type of cluster analysis, for the words in the sentiment dictionary. We set up 7 sentiment clusters (negative: anger, sadness, surprise, disgust; neutral: anxiety; positive: trust and joy) and conducted sentiment analysis of the tweet groups and retweet groups.

Results

The analysis revealed a mix of positive and negative sentiments, with “joy” significantly increasing in the retweet group after the state of emergency declaration. Negative emotions, such as “worry” and “disgust,” were prevalent in both tweet and retweet groups. Furthermore, the retweet group had a tendency to share more negative content compared to the tweet group.

Conclusions

This study conducted sentiment analysis of Japanese tweets and retweets to explore public sentiments during the early stages of COVID-19 in Japan, spanning 2 weeks before and after the first state of emergency declaration. The analysis revealed a mix of positive (joy) and negative (anxiety, disgust) emotions. Notably, joy increased in the retweet group after the emergency declaration, but this group also tended to share more negative content than the tweet group. This study suggests that the state of emergency heightened positive sentiments due to expectations for infection prevention measures, yet negative information also gained traction. The findings propose the potential for further exploration through network analysis.

BACKGROUND

Digital technologies can assist and optimize health care processes. This is increasingly the case in the musculoskeletal health domain, where digital platforms can be used to support the self-management of musculoskeletal conditions, as well as access to services. However, given a large proportion of the population with musculoskeletal conditions are older adults (aged ≥60 years), it is important to consider the acceptability of such platforms within this demographic.

OBJECTIVE

This study aims to explore participants’ opinions and perceptions on the use of digital platforms for supporting the self-management of musculoskeletal conditions within older adult (aged ≥60 years) populations and to gather their opinions on real examples.

METHODS

A total of 2 focus groups (focus group 1: 6/15, 40%; focus group 2: 9/15, 60%) were conducted, in which participants answered questions about their thoughts on using digital health platforms to prevent or manage musculoskeletal conditions. Participants were further presented with 2 example scenarios, which were then discussed. Interviews were audio recorded, transcribed, and analyzed thematically. Participants were aged ≥60 years and with or without current musculoskeletal conditions. Prior experience of using smartphone apps or other digital health platforms for musculoskeletal conditions was not required. Focus groups took place virtually using the Teams (Microsoft Corp) platform.

RESULTS

A total of 6 themes were identified across both focus groups: “experiences of digital health platforms,” “preference for human contact,” “barriers to accessing clinical services,” “individual differences and digital literacy,” “trust in technology,” and “features and benefits of digital health technologies.” Each theme is discussed in detail based on the interview responses. The findings revealed that most participants had some existing experience with digital health platforms for preventing or managing musculoskeletal conditions. Overall, there was a lack of trust in and low expectations of quality for digital platforms for musculoskeletal health within this age group. While there was some concern about the use of digital platforms in place of in-person health consultations, several benefits were also identified.

CONCLUSIONS

Results highlighted the need for better communication on the benefits of using digital platforms to support the self-management of musculoskeletal conditions, without the platforms replacing the role of the health care professionals. The concerns about which apps are of suitable quality and trustworthiness lead us to recommend raising public awareness around the role of organizations that verify and assess the quality of digital health platforms.

Актуальність. Аналіз динаміки медико-демографічних показників в Україні виявляє несприятливу демографічну картину з ознаками явищ депопуляції, що актуалізує вирішення пріоритетних завдань із збереження репродуктивного здоров’я не тільки жінок фертильного віку, а й чоловіків. Метою дослідження є ретроспективний аналіз формування структури та рівнів захворюваності, поширеності хвороб сечостатевої системи серед населення України в цілому та чоловічого населення, зокрема. Матеріали та методи. Матеріалами для дослідження слугували медико-демографічні дані офіційної статистичної звітності щодо захворюваності та поширеності хвороб за класом хвороб сечостатевої системи в розрізі основних адміністративних територій областей України та м. Києва за період 2010-2017 рр. з розподілом за статтю. Використані методи дослідження: системного підходу, бібліосемантичний, медико-статистичний, графічного аналізу, контент-аналізу. Результати. Аналіз гендерних аспектів формування захворюваності за класом хвороб сечостатевої системи виявив суттєве переважання як абсолютної кількості випадків вперше встановлених діагнозів за цим класом хвороб у жінок (у 5,5 рази (р<0,001)), так і відносних показників захворюваності за класом хвороб сечостатевої системи в розрахунку на 100 тис. відповідного населення (в 4,5 рази (р<0,001)). Наведена структура захворюваності жінок та чоловіків за означеним класом хвороб. Регіональні особливості захворюваності населення України за класом хвороб сечостатевої системи проявилися найвищими її рівнями за підсумками 2017 р. у Дніпропетровській (8 209,7) області та в м. Києві (6 980,5 на 100 тис. населення). Аналіз динаміки поширеності хвороб сечостатевої системи виявив зростання питомої ваги цього класу в загальній структурі поширеності хвороб серед населення України з 3,18 % у 2010 р. до 3,5 % у 2017 р. Регіональні особливості поширеності хвороб сечостатевої системи проявилися традиційно найвищими значеннями показника в м. Києві (16 270,5) та Дніпропетровській області (15 870,7) з мінімальним значенням показника в Луганській (4 906,6) та Закарпатській (5 745,6 на 100 тис. населення) областях. У структурі поширеності хвороб сечостатевої системи у чоловіків найбільшу питому вагу мали: хвороби передміхурової залози (35,6 %, або 1 810,9); інфекції нирок (22,7 %, або 1 155,3); хронічний пієлонефрит (21,1 %, або 1 071,0 на 100 тис. відповідного населення). Найвищі рівні поширеності хвороб передміхурової залози традиційно виявлялися в м. Києві (932,0 та 5 156,8 відповідно), Миколаївській (883,8 та 2 833,9 відповідно) та Харківській (749,0 та 3 107,3 на 100 тисяч чоловічого населення відповідно) областях. Висновки. Моніторинг регіональних, гендерних особливостей формування показників захворюваності, поширеності хвороб сечостатевої системи може стати аргументованим інформаційним підґрунтям для формування регіональних програм та заходів із збереження та зміцнення репродуктивного здоров’я серед чоловіків та жінок України.

Application of Real-time PCR with Mitochondrial D-Loop Specific Primers for Halal Authentication: Identifying Bovine Adulteration in Meatball Products
Authors: Arini Rien Larasati , Rohman Abdul , Rumiyati
Published: December 2023

This study aimed to develop an analytical method using Real-time PCR and a specific primer to analyze bovine DNA in meatballs, addressing the issue of non-halal meat being used in halal meatballs. Real-time PCR enables rapid, specific, and sensitive detection, allowing for qualitative and quantitative identification of species in processed products. The research involved designing specific primers for bovine DNA using IDT software, followed by DNA isolation and testing for various parameters such as specifications, linearity, limit of detection, efficiency, and repeatability. The results demonstrated that the primer D-Loop 922 (forward: 5-ATTACCATGCCGCGTGAA-3', Reverse: 5'-GATGAGATGGCCCTGAAGAAA-3'), designed and tested in silico using Primer-BLAST software from NCBI, effectively identified bovine DNA in both fresh meat and meatballs at an optimum annealing temperature of 59.5°C. The real-time PCR method utilizing the D-loop 922 primer successfully amplified bovine DNA in both bovine samples and bovine meatballs at a minimum concentration of 1 ng, with coefficients of variation (CV) of 0.20% for bovine DNA and 0.22% for bovine meatballs. Consequently, the D-loop 922 primer met the testing criteria and can be utilized to authenticate the halal status of meatball products, supporting the implementation of Law No. 33 of 2014 regarding halal certification.

Bejana tekan adalah wadah tertutup yang dirancang untuk menampung fluida yang mempunyai tekanan berbeda dengan tekanan lingkungan. Tekanan operasi bejana tekan dapat berupa tekanan internal, tekanan eksternal ataupun kombinasi antara keduanya. Perancangan bejana tekan mengacu ke ASME VIII divisi 1 menggunakan tekanan operasi internal dalam menentukan tebal shell bejana tekan, sedangkan beban tekanan eksternal dikompensasi dengan penambahan stiffener ring. Analisa tebal shell dengan tekanan eksternal perlu dilakukan untuk mengetahui tebal bejana tekan yang sesuai untuk menahan beban tekanan operasi eksternal. Pada penelitian ini dilakukan simulasi finite elemet menggunakan software Abaqus untuk bejana tekan aplikasi bawah laut pada beban tekanan eksternal 2 MPa. Simulasi dilakukan dengan beberapa variasi ketebalan shell baik tanpa menggunakan stiffener ring dan dengan menggunakan beberapa variasi geometri stiffener ring. Variasi tebal shell pada penelitian ini adalah 2 mm, 3 mm dan 4 mm. Selanjutnya simulasi dilakukan dengan penambahan tiga bentuk stiffener ring yang berbeda. Simulasi dengan tiga tipe stiffener ring dilakukan untuk setiap variasi ketebalan shell secara bergantian. Dari hasil simulasi menggunakan variasi tebal tersebut didapatkan pendekatan shell 2,5 mm tanpa menggunakan stiffener ring mampu menahan beban tekanan eksternal 2 MPa dengan eigenvalue 1,179 dan tegangan von Mises yang terjadi adalah 144,5 yang mana masih di bawah yield stress dari material bejana tekan. Dari hasil simulasi, stiffener ring tipe dua dengan rasio contact 0,022 menunjukan paling optimal menambah kekuatan bejana tekan untuk mencegah buckling ditunjukan dengan eigenvalue yang lebih besar dibandingkan hasil simulasi dari variasi lainya.

Pompa sentrifugal adalah alat yang sangat penting bagi berbagai macam peralatan industri. Performa pompa dipengaruhi oleh beberapa faktor seperti adanya rugi – rugi volumetrik, rugi – rugi mekanik, dan rugi – rugi hidraulik yang menyebabkan adanya penurunan di dalam efisiensi. Pada penelitian ini dilakukan simulasi pompa sentrifugal berbasis Computational Fluid Dynamics (CFD) dengan meneliti tujuh model pompa yaitu pompa rumah keong tunggal, pompa rumah keong ganda, pompa rumah keong dengan 2 sekat, pompa rumah keong besar, pompa rumah keong kecil, dan pompa dengan rumah keong penampang lingkaran. Tujuan dari penelitian ini adalah melakukan karakterisasi dari ketujuh model pompa. Simulasi ini menggunakan software ANSYS dengan pemodelan turbulensi menggunakan model k – ω sst. Dari ketujuh model tersebut didapatkan hasil bahwa nilai efisiensi dari pompa rumah keong  kecil memiliki nilai yang paling tinggi pada kondisi debit rendah sampai menengah. Akan tetapi, dengan bertambahnya debit aliran, pompa rumah keong tunggal memiliki nilai efisiensi yang paling baik..
