Authors: Hussein Hasan Qahtan , Fayyadh Ekhlas M. , Hasan Moayed R. 
Published: June 2024

Abstract
The objective of this review article is to provide a comprehensive analysis of the latest research on microchannel heat sinks, with a particular focus on single-phase flow, flow boiling, and coating microchannels. The review aims to highlight the progress made in this field and identify the challenges that need to be addressed to promote the widespread adoption of microchannel heat sinks. The review article examines the research on microchannel heat sinks and analyzes the findings related to single-phase flow, flow boiling, and coating microchannels. The analysis of single-phase flow in microchannels covers the impact of various parameters, including channel size, fluid properties, and flow conditions, on the heat transfer rate. The analysis of flow boiling in microchannels includes the identification of the potential advantages and challenges associated with this technique, as well as the strategies developed to mitigate these issues. The analysis of coating microchannels examines the effects of surface coatings on flow behavior and heat transfer performance. The review finds that microchannel heat sinks have gained significant attention due to their potential for high heat transfer rates in a compact size. The analysis of single-phase flow reveals that the heat transfer rate is proportional to the channel diameter and inversely proportional to the fluid viscosity. Increasing the flow rate results in higher heat transfer rates and pressure drops. The analysis of flow boiling reveals that this technique can significantly increase the heat transfer rate compared to single-phase flow. However, it can also lead to flow instability, wall superheat, and premature drying. The review identifies strategies to mitigate these issues, including using different surface coatings, enhancing nucleation, and optimizing channel geometry. The analysis of coating microchannels shows that coatings can alter the surface energy, wettability, and roughness of the channel walls, affecting the flow behavior and heat transfer performance. Coatings made from materials such as metals, polymers, and self-assembled monolayers have been investigated, and their effects on the flow of boiling heat transfer have been analyzed. The review highlights the need for further research to address the challenges associated with microchannel heat sinks, including flow instability and premature drying. Additionally, the review suggests that there is a need for more comprehensive studies on the effects of different surface coatings on flow behavior and heat transfer performance. Future research can also explore the potential of other materials for coating microchannels and investigate new strategies to optimize channel geometry and enhance nucleation. The review article concludes that the progress made in understanding microchannel heat transfer is significant, but further research is necessary to realize the full potential of microchannel heat sinks.

Authors: Mohammed Safaa , Hasan Afrah 
Published: June 2024

Abstract
Construction projects in Iraq suffer from many complex problems. Therefore, the aim of this study is to identify the most critical factors affecting the performance of Iraqi construction projects, delving into their identification, analysis, and understanding. A comprehensive list of 32 influential factors was compiled through site surveys, interviews with engineers and experts, and a review of previous research. These factors were categorized into eight groups: planning and management, design and engineering, procurement and supply chain, workforce and labor, technology and innovation, environmental and regulatory aspects, site conditions and infrastructure, and external factors. One hundred and ten questionnaires were distributed to project stakeholders, including owners, consultants, and contractors. The results found that the five most important factors affecting performance ranked using the relative importance Index are poor planning, failure to allocate resources properly, unavailability of skilled labor, poor labor productivity, and volatile economic conditions. Based on these results, for solutions to be effective, they must be adapted to the local environment. Project participants must be interested in planning as it is essential to address the same. The skills of project workers must be developed through training programs. Communication with project stakeholders must be coordinated to contribute to the decision-making process.
PointNet-based modeling of systematic distance deviations for improved TLS accuracy
Authors: Hartmann Jan , Ernst Dominik , Neumann Ingo , Alkhatib Hamza 
Published: June 2024

Abstract
Terrestrial laser scanners (TLSs) have become indispensable for acquiring highly detailed and accurate 3D representations of the physical world. However, the acquired data is subject to systematic deviations in distance measurements due to external influences, such as distance and incidence angle. This research introduces a calibration approach by applying a deep learning model based on PointNet to predict and correct these systematic distance deviations, incorporating not only the XYZ coordinates but also additional features like intensity, incidence angle, and distances within a local neighbourhood radius of 5 cm. By predicting and subsequently correcting systematic distance deviations, the quality of TLS point clouds can be improved. Hence, our model is designed to complement and build upon the foundation of prior internal TLS calibration. A data set collected under controlled environmental conditions, containing various objects of different materials, served as the basis for training and validation the PointNet based model. In addition our analysis showcase the model’s capability to accurately model systematic distance deviations, outperforming existing methods like gradient boosting trees by capturing the spatial relationships and dependencies within the data more effectively. By defining test data sets, excluded from the training process, we underscore the ongoing effectiveness of our model’s distance measurement calibration, showcasing its ability to improve the accuracy of the TLS point cloud.

Abstract

Objective
This study aimed to evaluate the efficacy and safety of solid organ transplantation recipients inoculated with an inactivated COVID-19 vaccine.

Methods
We retrospectively analyzed the antibody levels and related adverse events of non-transplantation subjects and solid organ transplant recipients, both pre-transplantation (individuals awaiting organ transplantation) and post-transplantation (individuals who have undergone organ transplantation), who received inactivated COVID-19 vaccines from February 2021 to July 2022.

Results
The study included 38 pre-transplantation vaccination group, 129 post-transplantation vaccination group, and 246 non-transplantation group. The antibody titer was assessed monthly within the period of 1–12 months after the last injection. The antibody-positive rate among the three groups were 36.84, 20.30, 61.17% (P < 0.05). The antibody-positive rates among three groups with one, two doses vaccine were not significantly different (P > 0.05), but were significantly different after three doses (P < 0.05). The antibody titers among three groups were significantly different after two doses (P < 0.05). Adverse reactions occurred in six transplant recipients, which were relieved after treatment, and not in the non-transplantation subjects.

Conclusion
Inactivated COVID-19 vaccine is safe and effective for solid organ transplantation recipients, at least two doses of which should be completed before organ transplant surgery.

Authors: Tanasi Davide , Levi Sara Tiziana , Caso Gianpiero , Tykot Robert H. , Greco Enrico 
Published: June 2024

Abstract
This study presents an in-depth archaeometric investigation of Iron Age ceramic assemblage dating from 950 to 750 BCE from the sanctuary at Polizzello Mountain, Sicily. The site, a key sanctuary utilized by indigenous communities for ritual activities, is examined for its strategic location, structural developments, pottery assemblages, and evidence of communal activities. The study employs petrographic analysis on thin sections, integrated with other analytical methods, to explore the technology behind pottery production. It investigates whether such production reflects a common technological knowledge shared by a broader community or if they represent a blend of different manufacturing traditions. The findings highlight that the pottery from Polizzello Mountain aligns with the well-established Sicilian tradition of combining calcareous components and grog, indicating a local tradition of pottery production with no significant compositional differences suggesting specialized production at the workshop level.
Summary of seven Swedish case reports on the microwave syndrome associated with 5G radiofrequency radiation
Authors: Hardell Lennart , Nilsson Mona 
Published: June 2024

Abstract
The fifth generation, 5G, for wireless communication is currently deployed in Sweden since 2019/2020, as well as in many other countries. We have previously published seven case reports that include a total of 16 persons aged between 4 and 83 years that developed the microwave syndrome within short time after being exposed to 5G base stations close to their dwellings. In all cases high radiofrequency (RF) radiation from 4G/5G was measured with a broadband meter. RF radiation reached >2,500,000 to >3,180,000 μW/m2 in peak maximum value in three of the studies. In total 41 different health issues were assessed for each person graded 0 (no complaint) to 10 (worst symptoms). Most prevalent and severe were sleeping difficultly (insomnia, waking night time, early wake-up), headache, fatique, irritability, concentration problems, loss of immediate memory, emotional distress, depression tendency, anxiety/panic, dysesthesia (unusual touched based sensations), burning and lancinating skin, cardiovascular symptoms (transitory high or irregular pulse), dyspnea, and pain in muscles and joints. Balance disorder and tinnitus were less prevalent. All these symptoms are included in the microwave syndrome. In most cases the symptoms declined and disappeared within a short time period after the studied persons had moved to a place with no 5G. These case histories are classical examples of provocation studies. They reinforce the urgency to inhibit the deployment of 5G until more safety studies have been performed.

Published: June 2024

AbstractObjectivesChronic pain is highly prevalent in nursing home residents and often occurs with depression as well as cognitive impairment, which can severely influence and limit the expression of pain.MethodsThe present cross-sectional study aimed to estimate the prevalence of pain, depressive mood, and cognitive impairment in association with pharmacological treatment against pain and depressive symptoms among Swedish nursing home residents.ResultsWe found an overall pain prevalence of 52.8%, a prevalence of 63.1% for being in a depressive mood, and a prevalence of cognitive impairment of 68.3%. Among individuals assessed to have depressive mood, 60.5% were also assessed to have pain. The prevalence of pharmacological treatment for pain was 77.5 and 54.1% for antidepressants. Prescription of pharmacological treatment against pain was associated with reports of currently having pain, and paracetamol was the most prescribed drug. A higher cognitive function was associated with more filled prescriptions of drugs for neuropathic pain, paracetamol, and nonsteroidal anti-inflammatory drugs (NSAIDs), which could indicate an undertreatment of pain in those cognitively impaired.ConclusionIt is important to further explore the relationship between pain, depressive mood, and cognitive impairment in regard to pain management in nursing home residents.

Published: June 2024

To analyze the correlation between leptin and cortisol after a concurrent training (CT) session. Thirty male volunteers (age: 27.7 ± 5.1 years, BMI: 27.08 ± 1.42 kg/m2) were randomly assigned to an experimental group (EG: n=15) and a control group (CG: n=15). Baseline leptin and cortisol levels were determined by collecting blood samples. EG was subjected to CT (indoor cycling followed by strength training), whereas CG performed no exercise. After CT, blood samples were collected in EG and CG to determine the hormone variables. EG showed a significant decrease (p<0.05) intra and intergroup in leptin and cortisol levels. Only the EG showed a significant correlation (r=0.756; p<0.05) between leptin and cortisol levels. CT session is linked to in decreased leptin and cortisol levels, exhibiting a positive correlation between them.

The objective of the study was to evaluate the Self-Assessment of Health (SAH) in elderly individuals before and after participating in a physical exercise program. It was a quasi-experimental study conducted with 96 elderly participants ( = 67 ± 6.07 years) enrolled in a 16-week physical exercise program. Before and after the program, participants filled out a medical history form and the Short Form 36 Health Survey Questionnaire (SF-36). The study found a prevalence of obesity (75.6%), with the predominant health conditions being hypertension (27.08% of the sample) and diabetes (5.21%), while 7.29% reported having both conditions. A notable enhancement in SAH was observed following the completion of the exercise program, both in terms of physical health (∆%= 3.75%, p = 0.0002), mental health (∆%= 17.95%, p = 0.004), and the overall SAH index (∆%= 6.75%, p = 0.001). This suggests the importance of physical exercise programs for the self-assessment of health in elderly individuals.
Thoughts on the entanglement of electromagnetism and life: A theoretical study
Authors: Zsarnovszky Attila 
Published: June 2024

AbstractDissection of the matter into its constituents leads us to the smallest particles that we know. These particles form a material structure that is determined by the electromagnetic field generated and carried by those particles. Changes in any of the two major constituents leads to changes in that material system, be it a living organism or a lifeless object. The latter statement carries the mystery of life that is born from a continuous and programmed series of system changes fuelled by an energy source with a yet unknown functioning mechanism. The present work is a theoretical approach towards the understanding and potential discovery of the aforementioned, not-yet-known cellular energetic mechanism. Understanding the energetic basis of intracellular biochemistry is equally important in human and animal therapeutics. Additionally, as all such discoveries offer novel solutions in various fields of the global industry, the final outcome of this theoretical work also brings about the idea of a new discovery in electronics industry.

AbstractThe interplay of regulatory T cells (Tregs) within the tumour microenvironment presents a significant challenge in anticancer immunotherapy. This study investigates the potential of Treg blockade to enhance the efficiency of effector T cells. Two distinct treatment cocktails were examined: 3p-hpRNA (5′ triphosphate hairpin RNA) combined with unmethylated CpG oligonucleotide (CpG); CpG in combination with OX40 receptor-specific monoclonal antibody (anti-OX40). Treatment efficacy was assessed using a murine model of kidney adenocarcinoma.Renca cells (renal cortical cells with adenocarcinoma) were subcutaneously engrafted in 30 BALB/c mice, then animals were allocated into three treatment groups: Group 1: CpG+anti-OX40, Group 2: CpG+3p-hpRNA, Group 3: untreated control. Treatment efficacy was evaluated based on tumour growth, the occurrence of metastases and overall survival.On day 28 post-implantation, experiments had to be terminated due to tumour progression. Although comparisons of survival times and primary tumour sizes thus became inconsequential, histological examinations provided valuable insights. We observed distinct variations in primary tumour characteristics among the different groups: Groups 1 and 2 displayed demarcations, while Group 3 exhibited diffuse tumours with necrosis. Lung metastases were evident in 70% of untreated mice, whereas none were observed in either of the treated groups.Our findings instil confidence in the potential efficacy of the treatments, thereby laying a solid foundation for future investigations.

Conceptual Principles of the Upbringing Function in Russian Civil and Family Law
Authors: Bogdanova E. E. , Bogdanov E. V. 
Published: June 2024

The paper analyzes the influence of the norms of civil and family law on the upbringing of a person. First, the authors focus on the powerful educational potential of the principles of integrity and justice. The paper also analyzes provisions of Russian civil and family law that require achieving a balance of personal and public interests (the principle of combining personal interests with public ones). The paper highlights that upbringing as a function is not only known to civil and family law, it is the main, defining function of Russian civil and family law. This function is aimed at educating or re-educating participants of civil and family law in a direction appropriate for society. According to the authors, legislative recognition of the upbringing functions of civil and family law is necessary. This can be solved by the preamble in the Civil Code of the Russian Federation and the Family Code of the Russian Federation, where, among other tasks and directions of the relevant legislation, the upbringing function is indicated. The principles of good faith, justice, and a combination of personal interests with public ones form the foundations of upbringing functions in Russian civil and family law, since the existence of a person as a biosocial being outside society is impossible.
The New in the Legal Regulation of the Organization and Activities of Homeowner Associations
Authors: Kachalova A. V. 
Published: June 2024

To date, such an organizational and legal form of a legal entity as a homeowner association is widespread and is in demand by participants of civil relationships, and in practice there are problems of organization and activity of its individual types that need independent research. In particular, this applies both to a homeowner association, the organization and activities of which are regulated by a special law, and partnerships for which there is no special legislative regulation. In connection with the above, the author explores a number of problems of the organization and activity of homeowner associations. Firstly, the problem of applying legislation to these relations by analogy. Secondly, the problem of the emergence of the right of common shared ownership of members of homeowner association, including those formed by owners of land plots united by a common territory, infrastructure and communications to common property. Thirdly, the problem of the exercise of membership rights and performance of duties by persons who do not have the status of a member of the homeowner association. Fourthly, the problem of the transfer of common property located within the boundaries of the homeowner partnership into common shared ownership. The author highlights the differences in law enforcement practice and identifies some other problems that arise due to the lack of legal regulation of the organization and activities of certain types of homeowner partnerships.
