In the era of the booming cosmetics industry, safety and efficacy evaluation have become crucial aspects in ensuring product quality and meeting consumer demands. The Chinese cosmetics market has witnessed rapid development. With an increasing emphasis on the safety and efficacy of cosmetics, a relatively comprehensive evaluation system has been gradually established. As pioneers in the cosmetics industry, Europe and the United States also possess mature and advanced experience in this regard. Based on years of work experience in the fields related to cosmetics safety and efficacy evaluation, the author of this chapter has summarized the characteristics of China, Europe, and the United States in this area. For safety evaluation, the entry points include cosmetics raw materials, packaging materials, chemistry and microbiology, as well as human testing. For efficacy evaluation, it is classified into categories such as cosmetics for freckle—removing and whitening, anti-hair loss, sun protection, anti-aging, and acne—treatment, repair, soothing, and those suitable for sensitive skin. By integrating the application of new AI technologies, this chapter presents a relatively scientific evidence-based system for cosmetics safety and efficacy evaluation to boost the high-quality development of the cosmetics industry.

Published: February 2025

Tumor microenvironment (TME) plays a fundamental role in the progression as well as in the resistance to therapies in oral squamous carcinomas (OSCC). Cancer-associated fibroblasts (CAFs), despite being the most prominent non-immune cell types of stroma in cancer, are poorly characterized. CAFs play a fundamental role in modulating the cell cycle, stemness, and epithelial-mesenchymal transition (EMT) and are capable of conferring resistance to different types of therapies, including chemo/radiotherapy, EGFR inhibitors, and anti-PD-1/PD-L1 checkpoint inhibitors. To do this, CAFs secrete extracellular matrix components, where tumor cells are immersed, and release growth factors, chemokines, and metabolites that affect tumor cell properties. Therefore, they are associated with poor prognosis. Here, we summarize our current understanding of CAFs and their involvement in the OSCC resistance therapies, and we propose potential actions for targeting these cells.

Published: February 2025

Background: Extensive evidence demonstrates that neuronal autophagic and cytoskeletal elements play critical roles in neuroplasticity. Dysregulation of neuroplasticity has been implicated in the pathology of depression and post-traumatic stress disorder (PTSD). Transcription factor EB (TFEB) and stathmin are key regulators of autophagy and microtubule formation, respectively. Objectives: The current study aimed to compare the levels of hippocampal TFEB and stathmin proteins in PTSD and depressed animal models of rats. Methods: Three groups of male rat pups (n = 8) were used. The first group, designated as the depressed group, was exposed to maternal separation stress and related stressors. The second group, representing the PTSD model, was exposed to single-prolonged stress. The third group served as the control. Anxiety-like and depressive-like behaviors were evaluated using the elevated plus maze (EPM) and forced swimming test (FST). Hippocampal TFEB and stathmin protein levels were measured using western blotting. Data were analyzed using Prism software. One-way ANOVA and post hoc Tukey tests were performed to evaluate statistical differences between groups in behavioral tasks. Independent t-tests were used to assess differences in protein levels between groups. Results: The TFEB protein levels were increased in both PTSD and depressed rats, while stathmin levels were decreased. The effect of depression on TFEB expression was significantly higher than in PTSD. Conversely, stathmin reduction was more pronounced in PTSD compared to depressed rats. Conclusions: These results suggest that changes in stathmin and TFEB protein levels may be associated with anxiety- and depression-like behaviors.

Published: February 2025

Mergers and acquisitions are a company's strategy to improve efficiency and competitiveness, but this process faces legal and regulatory challenges. In Indonesia, mergers and acquisitions are regulated in Law Number 40 of 2007 concerning Limited Liability Companies and Law Number 5 of 1999 concerning the Prohibition of Monopoly Practices and Unfair Business Competition. In addition, the Business Competition Supervisory Commission (ICC) is tasked with supervising mergers so as not to harm the market. This study uses a literature study method by examining regulations related to mergers and acquisitions, including financial accounting standards such as PSAK 103 and PSAK 38. Data is collected from legal journals, academic articles, and official regulatory documents. The results of the study show that mergers must be carried out in accordance with the law to avoid monopoly and unfair business competition. Law Number 40 of 2007 regulates the merger process, starting from shareholder approval to notification to creditors and employees. Law Number 5 of 1999 prohibits mergers that have the potential to create monopolies, and ICC has the authority to assess and cancel mergers that are detrimental to the market. In conclusion, merger and acquisition regulations in Indonesia are quite comprehensive, but the main challenge lies in the effectiveness of supervision by ICC and legal certainty for business actors. It is necessary to increase the implementation of regulations so that mergers are carried out fairly and in accordance with the law.

Social Media, American Interests, and the Arab Spring
Authors: Cook Jordan
Published: February 2025

The events of the Arab Spring that began in 2010 changed the political face of many countries, including Egypt and Tunisia. The role the Internet played in fomenting activism against authoritarian governments on the Arabian Peninsula has been explored at length in the popular media in both the West and the East, with various reports either overstating or underrating its importance. The contribution of the Internet to the events of the Arab Spring has led to support of the idea that open access and a free Internet is necessarily a force for good. This paper contests that idea, exploring examples that highlight the dangers in believing it. While the ability of social media to reach large audiences in short periods, and allow them to not only view information, but contribute to it, influenced the quick spread of the Arab Spring, this was a feature of the uprisings, and not the cause of them.
Canadian Waste Tire Practices and Their Potential in Sustainable Construction
Authors: St. Pierre Davin Kristofer
Published: February 2025

This paper is an analysis of two provincial waste tire management programs and the potential that exists using repurposed tires in sustainable construction. In an effort to mitigate the environmental hazards waste tire piles present, Canadian provinces have responded in various ways to repurpose tires for several different uses. While the tire reprocessing programs of Nova Scotia and British Columbia produce a wide variety of different recycled-material products, they both depend on secondary industrial processes to break down the existing tire structure in to its bare components. To capitalize on the initial energy inputs that exist in tire fabrication and avoid further reliance on energy-intensive industrial reprocessing, waste tire use in sustainable construction is proposed. The pioneering architecture firm Earthship Biotecture is examined to highlight the potential that exists by reprocessing tires in rammed earth tire homes.
Digital Technology: Help or Hindrance? Remembering in the Twenty-first Century
Authors: Bloudoff Nicole
Published: February 2025

People are adapting to technologies such as smart phones, portable hard drives, USB keys and online repertoires that are easy to acquire and use. We access the internet from almost anywhere, as well as store documents, pictures, artwork, journals, and records on our external devices. Digital technology is useful, but is it eliminating our brain‘s ability to remember? This paper will identify possible future effects of digital technologies on human memory. The switch from physical to digital records has effectively changed our attitudes towards memorabilia, causing a proliferation of massive file storage, but less file usage. Humans are experiencing unique new ambivalence where their data is safe, yet always subject to technical malfunction. Message interruption research has shown negative results regarding average memory retention. Implications for information managers are also discussed–stressing the importance of creating backup copies, as well as introducing memory retention practices to the workplace.

Natural draught cooling tower operation during winter
Authors: Mijakovski Vladimir , Lutovska Monika , Mojsovski Filip , Spirovski Mile
Published: February 2025

Operation of natural draught cooling towers and its ability to cool water is solely dependent on ambient air parameters (temperature and humidity). During winter period, at low temperatures of external air, circulation of air through the natural draught cooling tower causes greater cooling of the water and appearance of ice on places where air enters into the tower. In such case, with proper operation of the system cooling tower - pump station, and by reducing water's cooling range, temperature of the cold water ought to be maintained at sufficiently high temperature level in order to avoid freezing of the water in the tower and appearance of ice at air entering surfaces.

Published: February 2025

Obtaining pressurized air represents a significant expenditure of energy for every branch of industry, and today it is simply unthinkable to exist industrial plants without the production, distribution and use of pressurized air. This is particularly representative in the wood processing industry where it has been shown that there is a low awareness of the savings that can be made with the produced air under pressure, starting from its proper use to the use of waste heat through recovery. Bearing the above in mind, research was carried out in companies of the wood industry in Serbia in order to analyze the economics of obtaining and adequate use of pressurized air. Also, solutions were suggested for the recovery of waste heat in screw and reciprocating compressor plants, which are most present in the wood processing industry, as shown by the survey. The conclusions were drawn in the form of guidelines for the rational use of pressurized air, which can bring significant savings in energy consumption and increase efficiency and productivity in work.

Published: February 2025

Coal combustion is a major contributor to environmental pollution, releasing various harmful pollutants, including mercury, which poses significant risks to soil and water quality through atmospheric deposition. For this reason, some countries have established regulatory limits on mercury emissions from coal combustion, requiring the use of advanced pollution control technologies to capture and effectively reduce mercury emission. In this study, the mercury content in coal, coal ash samples and flue gas from the Kolubara A thermal power plant is determined. The results show that the mercury concentration in coal was 0.73 mg/kg, whereas the concentrations in fly ash and bottom ash were 0.02 mg/kg and 0.03 mg/kg, respectively. The mercury concentrations in coal and coal byproducts were in accordance with existing literature. In addition, the overall mercury content in flue gas was 38.73 µg/Nm³, falling within the permissible emission limit for thermal waste treatment in Serbia. The calculated mercury emission factor was below the lower limit specified in the Air Pollutant Emission Inventory Guideline of the European Monitoring and Evaluation of Air Pollutants (EMEP/EEA). These findings provide useful data for long-term environmental monitoring and regulation of mercury emission from coal combustion in Serbia.

Authors: Đorđević Milan , Mančić Marko , Stefanović Velimir , Vukić Mića
Published: February 2025

The objective of this paper was to study the influence of high-intensity asymmetric heat flux at the wall on pressure drop and heat transfer in the Archimedean spiral coil made of transversely corrugated tube that was exposed to radiant heating and is supposed to represent heat absorber of parabolic dish solar concentrator. The working fluids were water and a mixture of propylene glycol and water (90% and 10% by volume, respectively). An increase in the heat flux density at the pipe wall affects the increase in the pressure drop and peripherally averaged Nu number in the considered geometry in all flow regimes. The effect is most noticeable in the laminar region and monotonically decreases with increasing Reynolds number and curvature ratio. The intensification of heat transfer is less compared to the increase in pressure drop with increasing heat load at the wall. Quantitative comparison of the obtained data with results in the literature is lacking due to significant differences between the considered geometries and experimental conditions.

Published: February 2025

The enormous amounts of energy consumed today for the production of thermal energy intended for households, on the one hand, and the reserves of all types of fuels available worldwide, on the other hand, require that a more rational consumption should be implemented among all consumers. One of the many enhancements to heating systems that aims to improve overall efficiency is the concentration of thermal energy output for a greater number of users, which produces a far better result. This has led to the implementation of a centralized supply of thermal energy for multiple buildings and facilities, residential blocks, and entire urban areas. This method of producing and transmitting thermal energy for heating purposes is called district heating. The thermal energy, produced centrally, is transferred via pipelines to substations, and then through heat exchangers and secondary networks to end-users. Due to the fact that energy consumption constitutes a significant part of the budgets of individual and collective users and requires compliance with the European Union directives on increasing efficiency in all spheres of energy transformation, there is a need for optimized production and consumption of thermal energy. Optimization involves adequate supervision of relevant parameters of the heating process, including production (boiler room), distribution (pipelines), transfer (substations), and consumption (end-user). Supervision entails the ability to command and monitor the operation and parameters of the process. To achieve this goal, the supervisory system must collect and display important process data to detect possible problems or causes of inefficiency in the process itself, thereby alerting the operator. The main goal of the supervisory system is to enable the operator to control and command a highly automated process. Therefore, supervision involves a series of tasks aimed at controlling the process and monitoring its parameters. The Supervisory Control and Data Acquisition (SCADA) system has wide application in district heating systems for monitoring, control, and data acquisition.

Authors: Ramli Rosfaraliza Azura , Hafez Mohamed Ahmed , Samsurijan Mohamad Shaharudin , Ebekozien Andrew
Published: February 2025

The economic development programme aims to increase income and reduce indigenous people's poverty while introducing indigenous economic resources. This study appraises indigenous people’s effectiveness of economic development programmes in Perak land development projects (RPS), Malaysia. The researchers adopted a mixed-method approach involving 300 respondents for the questionnaire survey and 15 interview participants in the selected locations in Perak, Malaysia. The qualitative data were analysed by thematic analysis and the quantitative data by SPSS software. Findings show different effects between RPS Legap, RPS Ulu Kinta, and RPS Air Banun. The implementation can be less successful at RPS Air Banun due to the threat of wildlife such as elephants and wild boars. The findings also show that the indigenous people in the area are not carrying out rubber planting projects because of the possible damage from the wild animals. This threatens Goal 1. The situation in RPS Ulu Kinta and RPS Legap is different; the indigenous people enjoy the crop project results by receiving monthly dividends. This study will contribute to informing policymakers to develop a platform for improving Malaysia’s indigenous programmes and, by extension, improve the achievement of Sustainable Development Goal 1 (Goal 1).

In the face of escalating climate change, airports worldwide are finding themselves at the mercy of extreme weather events. This research paper presents a comprehensive system that models key indicators, aiding airport management during such challenging weather conditions. The system adopts an integrated approach, combining various machine learning models to provide a detailed projection of an airport's future state, drawing from past occurrences. The heart of the system is a model that focuses on the airport's peak service rate. This model meticulously correlates weather conditions and runway configurations with the 99th percentile of observed throughput from the training dataset. As such, the peak service rate model provides an estimate of the airport's capacity, which is essential for effective planning and resource allocation. Moreover, the system includes a predictive model that assesses the likelihood of air traffic flow management regulations based on weather data and calendar information. The robustness of this model against noise and uncertainty in the training dataset is fortified by the application of confident learning techniques and the inclusion of monotonic constraints. The system further enhances its capabilities by forecasting the potential entry rate of regulations, expressed in hourly arrivals, providing valuable insights that can guide proactive decision-making. By seamlessly integrating these three models, the system serves as an effective tool for airport operators and airlines. It enables operational optimisation and the development of strategic plans to mitigate the effects of increasing weather-related disruptions.
