Authors: De Zoysa Rannulu Lakmali , Mohammed Lubna Ali , Abeygunawardane Rushan
Published: August 2024

A properly selected web conferencing tool can significantly enhance student engagement, motivation, and learning outcomes in online education. Hence, this study aims to produce a framework ordering the key features and associated sub-factors of web conferencing tools that Sri Lankan tertiary sector students prioritize for their online learning experience. A quantitative research method is deployed to get the student's opinions on the factors discovered in a previous study on “Expert opinion on selecting a web conferencing tool for synchronous online tertiary education in Sri Lanka”. The research hypothesis was tested using the Pearson Chi-square test, followed by exploratory and second-order factor analysis to rank the importance of sub-factors and main characteristics. The findings revealed that students prioritize collaboration features the most, followed by online event features, pricing, user-friendliness, customer support, security, online evaluation, performance, and screen-sharing. This framework offers valuable insights for Sri Lankan tertiary institutions to select web conferencing tools that truly align with student preferences. By incorporating these student-centric considerations, institutions can optimize the online learning experience, leading to improved engagement, learning outcomes, and ultimately, greater student satisfaction.

Authors: Pujianiki Ni Nyoman , Airlangga Komang Gede Putra
Published: August 2024

Bathymetry surveys today are often carried out using the echo-sounding method, but this method has disadvantages, such as requiring a lot of time and being quite expensive. Along with the development of technology, some alternative methods can be used to visualize bathymetry, such as remote sensing. Remote Sensing uses satellite imagery in the operation, while the technique to acquire bathymetry is called Satellite-Derived Bathymetry (SDB). This method uses an optical satellite with several color bands or multispectral images. In this research, a satellite used to map ocean depth is Sentinel-2. The SDB technique used in this research is the Lyzenga Algorithm. The Lyzenga algorithm uses multilinear logarithms in its operation and can be used using three optical image channels (blue, green, and red channels). Supported by the SDB algorithm, an analysis of research locations was carried out at several points in the waters of Bali Island due to the diversity of water characteristics such as sea depth and wave height. From several analysis results of different characteristic waters in Bali Island, We can see that many parameters impact the result of the Satellite to visualize bathymetry. The Satellite's optimal result for reading the bathymetry depth is approximately 30 meters. But in reality, some cases can interfere with the accuracy of Satellite visualizing bathymetry within this depth. Breaking waves, high water sedimentation, and some objects that could guide the Satellite to misread them as elevation.
Advanced Decision- Making Framework for Sustainable Energy Retrofit of Existing Commercial Office Buildings
Authors: Anarene Bengold
Published: August 2024

In the background of rising global initiatives to combat climate change and promote better energy management, retrofitting of current structures has become a major strategy. This abstract and literature review aims at presenting a full review of a decision-making approach that can be used in choosing sustainable options for energy retrofitting. This particular framework is designed to help guide retrofit decision-making due to the many issues that surround the process by providing an economic as well as an environmental and social context. Energy retrofitting means improving the existing structure or complex to decrease its energy intensity and have a negative impact on the environment. As stated earlier, it is a critical process for attaining sustainability goals and advancing the performance of buildings. But the decision on which retrofit measures should be implemented can be rather difficult because of the availability of a vast number of technologies and because more factors must be considered, such as cost and energy savings.
The decision-making framework provided in this article aims at categorizing retrofit selection into this list of features and views the current article as a way of making the process more efficient. It encompasses the life-cycle cost analysis (LCCA), the economic valuation, and the multi-criteria decision analysis tools and criteria. These tools facilitate the evaluation of financial viability, the advantages of climatically retrofitting, and the environmental effects of distinct retrofitting choices. The above-mentioned framework is exemplified with a case study of an office building retrofit project. The following case includes an example of the application of the mentioned framework and illustrates the explanation of how it helps to make decisions. Due to the consideration of costs, energy, and environmental performance, the framework enables the stakeholders to choose appropriate retrofit measures.
Other than the case study, the framework also focuses on the need to establish a sustainable energy retrofit DSS. Thus, the DSS supplements collected data on building performance, retrofit technologies, and economic aspects, which can be accessed by the stakeholders in real-time and with built-in facilities for scenario analysis. This system improves decision-making since retrofit results can be monitored and evaluated frequently. Both tools and strategies for the decision-making of sustainable energy retrofits bring a logical and systematic approach aimed at neutralizing the decision-making challenges related to retrofit selection. By applying economic, environmental, and social factors in the decision-making process, the framework assists the stakeholders in reaching energy efficiency and sustainability goals. The development of another strong decision-support system also improves the working of the framework and checks that retrofit projects are done efficiently and are strategic to the general goal of sustainable development.

Published: August 2024

A study examining lead concentrations in gas stations found a significant difference between workers and non-workers. Workers at gas stations, including those in generator maintenance, were found to have higher lead concentrations than non-workers. The concentrations ranged from 9.621 to 14.801 ppm at the unit filling gasoline station (Basra petrol) to 10.831 to 15.02 ppm at the Morgan filling gasoline station (Samawa gasoline).
The lower limits of lead concentrations were 9.267 and 13.542 ppm at Abu Ajaj filling station. The concentrations of lead in the blood of workers servicing gasoline-powered generators ranged from 9.821 to 13.82 ppm, while those in residential areas had concentrations between 10.01 and 13.524 ppm. The World Health Organization has set standards for lead concentrations in the blood, with permissible limits of 10 parts per million. The study highlights the need for increased awareness and regulation of lead exposure in gas stations.
The Regulation of SPRY4 Intronic Transcript 1 (SPRY4-IT1) on KIT Signaling and Imatinib Resistance of Gastrointestinal Stromal Tumor (GIST) Cells
Authors: Yu Yuanyuan , Jiang Zongying , Zhao Sien , Liu Cuiyun , Ma Jinhai , Li Shujing
Published: August 2024

BACKGROUND: SPRY4 intronic transcript 1 (SPRY4-IT1), is a long non-coding RNA coded by the intron of SPRY4. SPRY4 is highly expressed in gastrointestinal stromal tumor (GIST) and inhibits the tumorigenesis of GIST, but whether SPRY4-IT1 regulates the tumorigenesis of GIST or not remains unclear. Therefore, in this study, the regulation of SPRY4-IT1 expression and its role in GIST will be investigated.METHODS: GIST-T1 cells, and Ba/F3 cells which express KIT proto-oncogene (KIT) and SPRY4-IT1 were used as cell models. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to examine mRNA expression, while the protein expression and signal transduction were examined by western blot. The association between SPRY4-IT1 and KIT was examined by pull down of KIT and PCR. Cell proliferation, survival, and cell cycle progression were examined by cell counting kit-8 (CCK8) and flow cytometry.RESULTS: KIT mutants increased the expression of SPRY4-IT1 in GIST. SPRY4-IT1 bound to KIT, also enhanced the activation and expression of both wild-type KIT and primary KIT mutants, therefore increasing the activation of downstream signaling proteins AKT and ERK of KIT, GIST cell survival, and proliferation. In addition, SPRY4-IT1 reduced the sensitivity of wild-type KIT, or primary KIT mutants to the first-line targeted therapeutic drug of GIST, imatinib, which can inhibit KIT activation. Gaining drug-resistant secondary KIT mutants might be one of the main reasons of GIST recurrence after targeted therapy. Similar to wild-type KIT and primary KIT mutants, the activation and expression of secondary KIT mutants and their resistance to imatinib were also increased by SPRY4-IT1.CONCLUSION: The results indicated positive feedback between SPRY4-IT1 and wild-type KIT, primary KIT mutants or secondary KIT mutants, and the upregulation of AKT and ERK activation by SPRY4-IT1 in GIST cells, providing a new insight in the KIT signaling regulation in GIST, and the resistance of GIST to targeted therapy.KEYWORDS: SPRY4-IT1, KIT, GIST, SPRY4, signaling
Elephantopus scaber Linn. Leaf Extract Sensitizes Doxorubicin in Inducing Apoptosis in HSC-3 Tongue Cancer Cells through Inhibiting Survivin Activity at Thr34

Published: August 2024

BACKGROUND: Previous research has demonstrated the effect of Elephantopus scaber Linn. leaf extract (ESLE) on various cancer cell lines. However, research on the effects of ESLE on oral squamous cell carcinoma (OSCC), especially tongue cancer, is still lacking. Moreover, the apoptotic mechanisms induced by ESLE are not well understood and require further exploration. Therefore, this study was conducted to investigate the effects of ESLE on cell viability and apoptosis in human squamous cell carcinoma (HSC)-3 tongue cancer cells.METHODS: HSC-3 cells were treated with varying concentrations of ESLE, doxorubicin, and a combination of both. Cell viability and apoptosis were assessed using MTT and Sub-G1 assays. The expression levels of survivin and its phosphorylated form at threonine (Thr)34 were evaluated using Western blot analysis.RESULTS: ESLE exhibited a concentration-dependent cytotoxic effect on HSC-3 cells in decreasing cell viability (Kruskal Wallis, p=0.001) and increasing apoptotic cells (ANOVA, p=0.001) significantly. When combined with doxorubicin, ESLE further enhanced the induction of apoptosis compared with doxorubicin alone. The combined treatment resulted in a decrease in the levels of phosphorylated survivin (p-Surv) Thr34, indicating the inhibition of survivin's anti-apoptotic function.CONCLUSION: ESLE significantly enhances the efficacy of doxorubicin, thereby sensitizing its ability to induce apoptosis in HSC-3 tongue cancer cells. This sensitization occurs through the inhibition of survivin activity, particularly at the Thr34 phosphorylation site. These findings suggest that ESLE could serve as a potential adjuvant to improve the effectiveness of doxorubicin in inducing apoptosis in tongue cancer cells.KEYWORDS: Elephantopus scaber, doxorubicin, tongue cancer, HSC-3 cells, apoptosis, Survivin, Thr34 phosphorylation

Geriatric patients with acute kidney injury in the intensive care unit: the effect of vitamin B12 and albumin levels on survival
Authors: Erarslan Sertaş , Paşalı Kilit Türkan
Published: August 2024

Objectives: Acute kidney injury (AKI) is a common and critically important clinical entity in geriatric age group. In addition, higher mortality rates are seen in cases requiring intensive care treatment. We have aimed to investigate the effect of vitamin B12 and albumin levels on mortality in critically ill geriatric patients with AKI.
Methods: Geriatric patients hospitalised in the Intensive Care Unit with a diagnosis of AKI between 07.01.2014-07.01.2015 were retrospectively screened and included in the study. Two groups were formed from discharged and exited patients. General characteristics and laboratory values of the patients were scanned from the hospital archives and recorded. Statistically significant intergroup differences in terms of demographic characteristics, and biochemical values were determined by statistical analysis.
Results: A total of 103 patients, including 53 females were enrolled in the study, while 72.2% of the patients had prerenal AKI. The mortality rate was 47.57% in all patients. There was no difference between groups in terms of mortality rates, etiologic factors and KDIGO staging. Vitamin B12 was high and albümin was low the group who succumbed to death. In addition, mortality rates increased by 10% for every 100 units increase in vitamin B12 value and decreased by 22% for every 10 units increase in albumin value.
Conclusions: We have determined that an increase in albumin levels during clinical follow-up decreased mortality rates and an increase in vitamin B12 levels directly increased mortality rates. Hypoalbuminemia and high vitamin B12 levels were found to be independent predictive factors for mortality in AKI.
Enhancing Customer Loyalty in the E-Food Industry: Examining Customer Perspectives on Lock-In Strategies
Authors: Himpeler Sophia , Dill Arthur
Published: August 2024

Although management consultancies emphasize customer loyalty as an important factor for the profitability of e-food business models and various lock-in strategies are already being used successfully in foreign e-food markets, there is still a lack of implementation among German e-food providers. To derive how customer loyalty strategies should be designed in the German e-food market, this paper focuses on a qualitative-explorative analysis of which determinants characterize loyalty to an e-food provider from the customer’s perspective. The results of the study partly confirm the determinants for customer loyalty in e-commerce in general that have already been identified in other studies. It becomes clear that the consideration of the individual recurring needs of customers significantly strengthens customer loyalty in the e-food market. In addition, the characteristics of the German e-food market show that lock-in strategies from other European markets cannot be transferred to the German e-food market without conceptual adjustments.

Authors: Boyles Daniel Robert , Smith-Steinert Rachel , Hayes Jason
Published: August 2024

Introduction: The anesthesia technician is an integral asset to the anesthesia care team, increasing provider support and decreasing stress possibly leading to improved patient outcomes. While the profession of anesthesia has experienced advancement in recent years, the role of the anesthesia technician has remained underdeveloped. One basic role is the set-up of the anesthesia workstation. The purpose of this project was to design and administer anesthesia technician education on the operation of the anesthesia machine and to measure knowledge gained.
 
 
Methods:A six-item multiple choice pre-test was administered to the participants assessing basic anesthesia machine knowledge which was included in the education module. A post-test was administered immediately after the education to measure knowledge gained.The post-test included several demographic and qualitative questions for quality improvement.
 
Results: A pre-post test comparison demonstrated statistical significance. Overall test mean score increased from 38.9% to 62.5%. Demographics revealed many technicians were inexperienced and not certified. The education was received positively by participants with many requesting additional training.
 
Discussion: The benefits of trained technicians inside and outside of the operating room where support may not be readily available has been demonstrated. Trained technicians can reduce stress of the anesthesia providers improving team dynamics and most importantly patient safety with the potential for better outcomes.

Anesthetic Management of a Patient with Von Willebrand Disease
This case report describes an anesthesia-related adverse event encountered in the hospital operating room with regards to profuse esophageal bleeding intra operatively and post operatively in a patient with Von Willebrand disease (VWD) Type 1. Although Type 1 typically does not cause profuse bleeding, anesthesia providers should have a high suspicion of bleeding involving any procedures in the oropharynx such as TEE or EGD. Discussed are the anesthetic considerations of drawing baseline labs, assess the risk of bleeding, pretreat DDAVP and anticipate second line treatments. Have Humate-P available on site in case the bleeding is uncontrolled. Second line treatments include cryoprecipitate and tranexemic acid.

Published: August 2024

The American Association of Nurse Anesthetists (AANA) have a significant role in providing various benefits to their members and advancing the profession. However, membership percentages have decreased within the last 10 years. A review of the literature was conducted to identify the determinants that influence decision-making regarding professional association membership. It was discovered that Florida was among the states with the highest percentages of nonmembers. For that reason, a scholarly project was developed and implemented to examine the factors that influence decision-making regarding professional association membership among Florida’s licensed nurse anesthetists. An online survey was developed and sent to all Florida Certified Registered Nurse Anesthetists (CRNAs) with the help of the Florida Association of Nurse Anesthetists (FANA). The results of the survey revealed barriers to membership included dissatisfaction with the new National Board of Certification and Recertification for Nurse Anesthetists (NBCRNA) Continued Professional Certification (CPC) requirements, cost of membership, and a lack of education about the AANA. Determinants to membership identified included the benefit of CEUs and tracking, professional promotion, and the AANA’s political advocacy. There was insufficient power to compare FANA members’ and nonmembers’ responses due to a low nonmember response rate. However, sufficient information was derived to suggest implications and recommendations to help improve future research efforts and better understand the issue.

Capitalizing Networked Learning: Connectivism, Multiliteracies and the Architectonics of Pedagogy
Authors: Dennis Jeremy
Published: August 2024

As connectivism is increasingly accepted as a theory of learning for the digital age, scholars and practitioners in education often overlook the dilemma that this creates for its most ardent advocates. In the academic literature, we increasingly find scholarly works that present insouciant descriptions of connectivism. However, such practices often underplay or ignore critiques of connectivism, allowing many of our contentions about its epistemological character and pedagogical effectiveness to calcify. In fact, it is becoming increasingly difficult to rationalize why so many educators have endorsed connectivism as a new theory of learning when there continues to be a need for more empirical testing and greater philosophical substantiation. To illustrate this paradox, this paper examines Stephen Downes’s consideration of connectivism and his connectivist model of literacy. Using the dialogic philosophy of Mikhail Bakhtin, it introduces an architectonic model of connectivism and multiliteracies as an alternative discourse and pedagogical paradigm. A key finding from this study suggests that the lack of attention to capitalist practices, power, and the intermediality of texts in networked learning help to conceal the ways in which connectivist practices rearticulate behaviorism.

Two years after the introduction of the new Teaching Quality Standard in Alberta, Indigenous and non-Indigenous researchers from eight teacher education programs came together to examine how teachers were weaving Indigenous knowledges into their classrooms. The fifth competency of the standard requires that all Alberta teachers possess a foundational knowledge of First Nations, Métis, and Inuit and apply that knowledge in the classroom. Two hundred and forty-seven teachers, both non-Indigenous and Indigenous, responded to a survey, and another 30 participated in follow-up interviews. Results point to challenges and successes that teachers have experienced, the people that support their work, and how the integration of Indigenous knowledges acts as a tool to combat racism against Indigenous Peoples. Although teachers reported increased efficacy in applying a foundational knowledge of Indigenous Peoples, a multicultural perspective prevented some from understanding the unique nature of racism against Indigenous Peoples.
Constelações semiótico-discursivas
Authors: Campos Ferreira Matheus Henrique Menezes , Ramires Vicentina
Published: August 2024

Determinadas questões semióticas e discursivas chamam a atenção em relação à produção de possíveis sentidos e de possíveis impactos dessa produção na sociedade. Com esses pressupostos, objetivou-se proporcionar um diálogo entre as perspectivas semióticas de Benveniste (1989), Peirce (1999), Santaella (2000), Queiroz (2004) e Eco (2014) juntamente às ideias dos estudos críticos do discurso (VAN DJIK, 2020, 2021; FAIRCLOUGH, 2019; CHARAUDEAU, 2006), a fim de: i) identificar como elementos participativos de diferentes sistemas semióticos formam constelações a partir de perspectivas discursivas; ii) descortinar que o processo de formação de constelações proporciona o processo simbólico/ideológico com maior intensidade; e iii) indicar a articulação de signos por meio de um determinado discurso, de forma a permitir maior alcance e entendimento àqueles que compartilham das mesmas perspectivas discursivas. Para tratar essa temática, tomou-se como metodologia uma revisão bibliográfica, que posteriormente seria submetida à prova empírica, por meio de análises de postagens no Instagram de figuras políticas públicas inseridas no discurso bolsonarista e declaradamente apoiadoras da FPE (Frente Parlamentar Evangélica). Ao final das considerações e das análises, constatou-se que os processos e relações estabelecidos entre diferentes signos de diferentes sistemas semióticos podem estabelecer relações lógicas entre si por meio das pautas discursivas contextualizadas, como o meio, o instante da produção e o agente (re)produtor do texto. Essas relações, devido à forma como se articulam, abstratamente se configurariam como constelações.

Актуальність проведених досліджень полягає в необхідності встановлення фонових значень основних показників хімічного складу природних вод на території потенційного впливу гірничих підприємств. З отриманих результатів проб води можна констатувати, що якість води в цілому гірша у досліджених свердловинах в с. Олександрівка, с. Пустельникове, смт Балахівка та с. Новий Стародуб, ніж у р. Інгулець і р. Вівнянка й, навіть, у більшості водойм – як в кар’єрних озерах, так і ставках-запрудах. Зафіксовано перевищення гранично допустимих концентрацій у поверхневих та підземних водах за такими показниками як Ca, Mg, SO4, Na, K та Mn. Оцінка якості показала, що обстежені природні води за блоком загальносанітарних показників можна охарактеризувати як «добрі», чисті води прийнятної якості. Встановлена подібність досліджених вод за катіонним складом, натомість у аніонному складі є відмінності: у поверхневих водах переважає гідрокарбонат, у підземних водах – сульфат-іон. У подальшому необхідно проводити моніторингові спостереження за змінами хімічного складу поверхневих та підземних вод Південної ділянки Балахівського родовища графіту при роботі гірничо-видобувного підприємства.

З огляду на зниження якості природних вод, наявна потреба в передових методах пом'якшення питних та промислових вод зростає. Основна увага в цій сфері приділяється методам видалення іонів магнію та кальцію. Причому, магній важче видаляти через його тенденцію формувати менш розчинні сполуки. Загальний успіх пом'якшення залежить від можливості повного видалення цих катіонів з води. Увага наших досліджень була зосереджена на силікаті натрію як потенційному реагенті для пом’якшення води. Як було встановлено, висока ефективність у видаленні катіонів жорсткості забезпечується лише при високих значеннях pH, що вимагає додаткового регулювання водневого показника після пом`якшення. В нейтральному середовищі силікат натрію показав недостатню ефективність для процесів пом’якшення питних вод. Не зафіксовано значного покращення (в порівнянні із традиційними реагентами – карбонати, гідроксиди, фосфати) і в процесах відділення утвореної твердої фази. Освітлення оброблених розчинів відбувається надто повільно, а фільтрування характеризується швидкою кальматацією пор фільтру та суттєвим зниженням швидкості фільтрування. Ефективність відстоювання та фільтрування істотно не змінюється при зміні вихідної жорсткості води або пропорцій силікату натрію. В окремих випадках при низьких значеннях жорсткості утворення візуально помітного осаду взагалі на фіксується. Загалом, використання силікату натрію не супроводжується особливими властивостями в порівнянні з традиційним  реагентами тому не може забезпечити відповідних вимог для застосування у системах малої та середньої продуктивності.

Досліджено відносний вміст води (RWC) у тканинах листків рослин кукурудзи гібриду Трістан ФАО 270, вирощених за умов стресу від посухи в умовах дослідної станції Інституту сільського господарства Північного Сходу НААН України (Сумська область). Дослідна ділянка зазнавала водного стресу через обмежену кількість опадів під час критичних фаз росту в травні та червні.
Метою нашого дослідження було оцінити вплив мікробіологічних препаратів на основі бактерій, що стимулюють ріст рослин (PGPB), та їх метаболітів,  відомих своєю здатністю пом'якшувати водний стрес, на відносний вміст води у листках рослин кукурудзи, вирощеної за умов посухового стресу.
Встановлено суттєві відмінності між контрольними варіантами з рослинами кукурудзи та обробленими біопрепаратами ТОВ "ТД БТУ-ЦЕНТР": Азотофіт®, Липосам® та комплексом STOP-Стрес (Органік-Баланс® 0,5 л/га + Азотофіт ® 0,3 л/га + Липосам® 0,25 л/га). Рослини кукурудзи, оброблені Органік-Баланс® 0,5 л/га +  Азотофіт ® 0,3 л/га + "Липосам®" 0,25 л/га, мали найвищий відносний вміст води (97,3%) порівняно з контролем (86,7%).

У цій роботі було проведено дослідження для вивчення різних параметрів фітотоксичного ефекту у випадку забруднення ґрунту сирою нафтою, а також оцінено можливість зменшення токсичності нафтозабруднених ґрунтів за допомогою використання сорбентів. Як сорбенти використовували активоване вугілля та терморозширений графіт. Отримані результати свідчать про те, що сорбційний метод може бути перспективним у відновленні нафтозабруднених територій. При використанні терморозширеного графіту як сорбенту, фітотоксичний ефект не перевищував 20%.

Побудовано математичну модель механізму подрібнення розбиванням при ударному навантаженні в барабанному млині, який реалізується переважно при помелі твердих відходів. Застосовано метод чисельного моделювання, заснований на експериментальній візуалізації через прозору стінку поведінки зернистого навантаження в поперечному перерізі обертової камери. Вихідною характеристикою удару є усереднена вертикальна складова швидкості руху навантаження в зоні польоту на межі контакту з шаром зсуву. Формалізація моделі виявила вплив на енергоємність процесу масової частки зони польоту, оборотності навантаження та швидкості обертання. Встановлено раціональний режим ударного шліфування при відносній швидкості обертання ψω=0,75–0,9.

У роботі дається вирішення актуального завдання щодо забезпечення захищеності природного середовища та життєво важливих інтересів людини від негативних впливів пилових викидів, що утворюються при виробництві газобетонних будівельних виробів. Встановлено, що при використанні традиційних систем очищення пилових викидів циклонами в атмосферне повітря викидається пил, до 100 % маси якого припадає на частинки з розмірами до 20 мкм. При цьому їхній медіанний діаметр дорівнює 12 мкм, відсоток частинок з розмірами менше 10 мкм (РМ10) становить 40 %, відсоток частинок з розмірами менше 2,5 мкм (РМ2,5)  – 0,5%. Відсоток частинок в атмосферному повітрі біля проммайданчика влітку коливаються: для РМ10 – від 12 % до 40 %; для РМ2,5 – від 0,3 % до 0,5 %. На межі санітарно-захисної зони ці значення становлять 80% та 0,5% відповідно.

Контрольні списки видів різних угруповань використовуються як набори даних у численних екологічних, фітопатологічних та біоінформатичних дослідженнях. Однак, попри те, що Україна є однією з традиційних хмелярських держав, досі не було складено жодного контрольного списку видів комах, виявлених на хмелі звичайному (Humulus lupulus L.) в Україні. Тому метою дослідження було скласти контрольний список видів комах, що трапляються на рослинах хмелю в Україні. В результаті 150 видів комах, виявлених на H. lupulus, які належать до 115 родів, 41 родини та 8 рядів було нараховано. З цих видів 12 були основними шкідниками хмелю в Україні, а 14 - основними шкідниками у світі. Складений контрольний список може бути використаний у подальших дослідженнях можливих переносників збудників хвороб хмелю, видового різноманіття та багатства угруповань, пов'язаних з рослинами хмелю, а також для розроблення ефективніших заходів з управління чисельністю шкідників хмелю.
Physics at a Crossroads: Weird Concepts or Orthogonal Projections
Authors: Niemz Markolf H.
Published: August 2024

Einstein’s special relativity (SR) and general relativity (GR) describe nature in “subjective concepts” (concepts of observers), such as spatial and temporal distance, wave, particle, force, and field. The word “subjective” does not imply that SR/GR would be limited to one point of view. It implies that, despite the Lorentz covariance of SR and the general covariance of GR, any point of view in SR/GR is egocentric. Even coordinate-free formulations of SR/GR or all observers’ views taken together do not make a “holistic view” (comprehensive view from all possible perspectives at the same instant in time) because there is no absolute time in SR/GR. Here I show: Euclidean relativity (ER) describes nature in “objective concepts” (concepts that are immanent in all objects). “Pure distance” replaces spatial and temporal distance. “Pure energy” replaces wave and particle. Each object’s proper space d1, d2, d3 and its proper time τ span an absolute 4D Euclidean spacetime (ES), where d1, d2, d3 and d4 = cτ are pure distances. The invariant is absolute, cosmic time θ. All energy moves through ES at the speed c. An observer’s reality is created by orthogonally projecting the “master reality” ES to his proper space and to his proper time. In SR and GR, the two projections are reassembled to a non-Euclidean spacetime. Information is lost in projections. Thus, there will always be unsolved mysteries if we oppose ER. SR/GR are subordinate theories: Their subjective concepts describe an observer’s reality. ER describes ES and how his reality is created. On top, ER solves 15 mysteries purely geometrically, that is, without forces, fields, and weird concepts (cosmic inflation, expanding space, dark energy, non-locality). Why do physicists prefer weird concepts to two orthogonal projections?
Quantum Gravity: Parameters for Detection via Spin Entanglement and Theoretical Models
Authors: Kohli Anhad
Published: August 2024

Quantum gravity is crucial for unifying general relativity and quantum mechanics, which are two of the fundamental pillars of physics. Despite the significant advances in theoretical models of quantum gravity, experimental validation of these theories remains sparse. This review paper aims to address this gap by examining the experimental proposal by Bose et al., that aims to show the non classicality of gravity, alongside a discussion of semiclassical and quantum models and their shortcomings. We explore the Double Stern-Gerlach experiment to observe gravitational entanglement, detailing the procedure and the quantum states involved. The minimization of Casimir-Polder forces, which could interfere with the experiment, is highlighted as essential for optimizing conditions for maximal entanglement, calculated using von Neumann entropy, and measured using an Entanglement Witness. We discuss the inferences drawn from this experiment and introduce semiclassical gravitational models, outlining the assumptions made by Bose et al. Furthermore, we delve into perturbative Quantum Gravity (pQG) using the path integral approach, explaining its non renormalizability and the extent of its applicability. The conclusions indicate that observing entanglement would demonstrate the non-classicality of gravity. While semiclassical models are experimentally inaccurate, they serve as useful calculational tools for black hole physics. Although pQG has proved to be non-renormalizable so far, it functions as an effective field theory (EFT) at energies below 1019 GeV.
