Em busca de mais excitação
Authors: Cavalcante Fernando Resende
Published: November 2024

O objetivo deste ensaio é refletir acerca das apostas esportivas a partir da base teórica de Norbert Elias e Eric Dunning. Além disso, como suporte, analisa-se a estrutura dos sites de apostas esportivas e os estudos produzidos acerca do assunto. Assim, diante dos referenciais apresentados, conclui-se que os indivíduos que apostam no esporte estão em busca de mais excitação para além do que a assistência dessa atividade proporciona. Logo, se as apostas eram condimento para a excitação a fim de assistir uma luta, como apresentado por Elias no passado, hoje, certamente, diante da expansão do mercado das apostas esportivas, os indivíduos têm procurado cada vez mais esse condimento, ou seja, estão em busca de mais excitação.

Microbiological evaluation of packaging obtained from cosmetics production establishments
Authors: Contri Renata Vidor , Lagemann Danieli Cristina , Capp Zilles Julia
Published: November 2024

The cosmetics are commonly placed in plastic packaging that have the important function of protecting the product.  However, the cosmetics packaging can contribute to the total microbial load of the product, leading to product deterioration and putting the health of users at risk. The main purpose of this research was the microbiological evaluation of cosmetics packaging obtained from cosmetics production establishments (an industry and four compound pharmacies) from Vale do Taquari, Rio Grande do Sul, Brazil. Based on the results of a questionnaire applied at the moment of packaging acquisition, previous sanitization is performed for compound pharmacies packaging, with different handling of the packaging, whereas in the industry the process of packaging sanitization does not occur. However, this sanitization was not considered enough to guarantee the absence of microorganisms in the packaging, since a microbial growth was observed for 6 out of the 16 evaluated containers obtained from compound pharmacies, and for 2 out of the 4 industrial containers. Although several containers were contaminated, a few number of CFU/mL (from 1- 4) was isolated from each sample. Staphylococcus bacteria were the most common type of contamination, with S. aureus being identified in one sample. Not performing prior sanitization or storing packaging with the lid open led seems to lead to a higher microbial contamination of the packaging. Hence, both the sanitization process and the storage of packaging play an important role in guaranteeing packaging and cosmetics quality. The present investigation points for the importance of microbiological quality control of cosmetics packaging.

Authors: Singh Satyendra , Shukla Ram Mohan
Published: November 2024

Bladder cancer remains a significant health challenge. Early and accurate diagnoses are crucial for effective treatment and improved patient outcomes. In recent years, artificial intelligence (AI) has emerged as a powerful tool in the medical field, showing great promise in advancing the bladder cancer diagnosis. This review explores the current state and potential of AI technologies, including machine learning algorithms, deep learning networks, and computer vision, in enhancing the diagnostic process for bladder cancer. AI systems can analyze vast amounts of data from various sources, such as medical imaging, genomic data, and electronic health records, enabling the identification of subtle patterns and biomarkers that may indicate the presence of bladder cancer. These systems have demonstrated high accuracy in detecting cancerous lesions in imaging modalities such as cystoscopy, ultrasonography, and computed tomography scans, often surpassing human performance. Moreover, AI-driven diagnostic tools can assist in risk stratification, predicting disease progression, and personalizing treatment plans, thereby contributing to more targeted and effective therapies.
The Current Role of Metastasis-Directed Therapy for Oligometastatic Renal Cell Carcinoma
Authors: Kim Hyung Joon
Published: November 2024

Approximately 20% of newly diagnosed renal cell carcinoma (RCC) cases exhibit synchronous metastases, while 20% to 40% of initially localized RCC cases subsequently develop distant metastases after surgical intervention. In the management of oligometastatic RCC with a restricted number of metastatic sites, metastasis-directed therapy (MDT) plays a crucial role within the multimodal therapeutic framework. MDT, which encompasses surgical metastasectomy and stereotactic body radiation therapy (SBRT), seeks to prolong survival and increase quality of life by offering an interruption of systemic therapy. Research has demonstrated that complete metastasectomy is essential for attaining an optimal survival advantage. The criteria for patient selection remain ambiguous; nonetheless, it is crucial to consider the location of metastases and patient risk stratification. SBRT is demonstrably successful in RCC and is being progressively utilized in oligometastatic RCC. The sequencing of advanced systemic agents with comprehensive local treatment of primary and metastatic sites for oligometastatic RCC has demonstrated potential.
Natural resource tax as an instrument for sustainable environmental governance
Authors:   Latvia University of Life Sciences and Technologies, Leibus Inguna , Filipova Luize ,   Latvia University of Life Sciences and Technologies
Published: November 2024

To contribute to a more efficient use of resources and the transition to a circular economy by reducing the amount of landfill waste, environmental tax policies need to be well thought out. The research aims to assess the use of environmental taxes for fostering the circular economy. All EU Member States use taxes to solve environmental governance problems; however, the tax revenues as a percentage of GDP tend to decrease, which indicates that GDP growth outpaces an increase in taxes. Environmental taxes mainly consist of energy and transport taxes, while the proportion of pollution and resource taxes is relatively lower. To achieve environmental governance goals, both tax collection and tax relief are simultaneously used to contribute to waste and packaging management and reduce environmental impacts. Increasing tax rates alone is not enough to reduce the amount of landfill waste, and more attention should be paid to educating the population and increasing the role of local governments in sustainable environmental governance.

Authors: Srinivas B. , Bagadi Lavanya , Darimireddy Naresh K. , Surya Prasad P. , Satrupalli Sivaji , Anil Kumar B.
Published: November 2024

The amount of textual data on the internet is increasing enormously, so data
summarization into text has become essential. As generating text summaries
manually is an arduous task and humans are generally prone to make mistakes,
deep learning techniques have evolved to overcome this problem. Modified
transformer-based deep learning models with varying encoder-decoder and
feed-forward network layers are proposed to develop an abstractive summary
of the news articles. The proposed transformer model provides the advantage
of parallelization with the help of multiple attention head layers to
process long sentences, and hence, better text summarization performance is
achieved. These models are trained on an ?in-shorts? dataset, and the
proposed model is compared with the PEGASUS-CNNdaily-mail, BART-large-CNN,
and DistilBART-CNN-12-6 models on the CNN/DailyMail dataset. The performance
is evaluated in terms of the ROUGE score by comparing it with the existing
Recurrent Neural Network (RNN) model. The suggested transformer model
achieved a ROUGE score of 0.33, surpassing the RNN model score of 0.17. This
innovative approach can be employed on extensive textual data to extract
summaries or headlines.
A kőnyersanyag-forrásokkal való gazdálkodás kutatása Észak-Magyarországon
Authors: Mester Zsolt
Published: November 2024

In the third volume of the Litikum Books, we publish a summary of our project „Changes in the management of lithic resources from the Middle Paleolithic to the Middle Neolithic in Northern Hungary”, which started in October 2017. The initial hypothesis of our project was that the management of lithic raw material sources by prehistoric communities was influenced by natural, economic and cultural factors, and this complex interaction can best be examined in a time scale where significant climatic-environmental and economic-cultural changes took place. Our observations in Poland, Slovakia, Ukraine and Hungary have convinced us of how important it is to distinguish lithic raw material sources according to procurement, and what role geomorphological processes play in changing access.

Published: November 2024

Indigenous peoples are caretakers and practitioners of a unique culture connected to their community and the surrounding environment, including forests. In Indonesia, existing regulations acknowledge the identity of indigenous peoples and the forests they oversee. This paper provided evidence of the acknowledgment of customary forests and indigenous peoples, addressing the challenges and opportunities for managing customary forest products, both timber and non-timber, under a timber legality assurance scheme. This research is essential in advocating for legal reforms that protect the rights of indigenous peoples and ensure sustainable forest management while balancing environmental conservation with local community needs. The study sought to illuminate the challenges Indigenous Peoples encounter when accessing and utilizing forests and forest products within their customary territories. It employed exploration methods to gather reliable data and information, validated through expert interviews and described using triangulation. The research concluded that legal innovations are necessary to resolve issues concerning the recognition of customary forests and indigenous peoples to enable effective forest management while safeguarding the rights of indigenous peoples socially, economically, and ecologically. In addition, legal innovations are also required to avoid breaches of timber legality assurance, which can result in forest unsustainability. To enhance the effectiveness of these reforms, it is important to foster collaboration between government bodies and indigenous communities in developing and implementing forest management policies.

Authors: Kusumawardani Anisa , Suyatno Maulana Ihsan Yusufi , MS Dhian Andanarini , Salim Noor , Rama Eduardus
Published: November 2024

This research addresses the optimization of village fund management in Indonesia, particularly in the context of digitizing financial systems, self-efficacy, and self-esteem of village officials. The research gap stems from challenges faced by village officials, such as limited education and technostress, which impede the effective use of digital accounting systems. The purpose of this study is to examine how digitized information systems, alongside self-efficacy and self-esteem, influence the accountability of village fund management. Using multiple linear regression analysis, this study reveals that while the effects of digitization and self-efficacy on accountability are not statistically significant at the 5% level, they show weak significance at the 10% level, indicating a potential influence. The findings suggest that self-efficacy has the highest impact, followed by digitized system utilization, whereas self-esteem has the least effect. The results highlight the need for improved technological adoption among village officials to enhance financial management practices. Further research is recommended to explore the long-term impact of these factors and to validate these findings with larger sample sizes. This study concludes that optimizing village fund management is essential for ensuring sustainable development and improving the welfare of rural communities in Indonesia.

МЕДИЦИНСКОЕ ПРАВОНАРУШЕНИЕ В РОССИЙСКОМ ЗАКОНОДАТЕЛЬСТВЕ: ОШИБКА ВЫЖИВШЕГО
Authors: Тихомиров Алексей
Published: November 2024

Медицинское правонарушение в российском законодательстве, как и в правоприменении, остается категорией проблемной и противоречивой. Законом и доктринальным мейнстримом опускаются детерминанты неблагоприятных для здоровья пациента эффектов при оказании ему медицинской помощи. При оценке действий врача зависимые и независимые от них факторы влияния на здоровье пациента юридически не обособляются. Не существует ни теории, ни практики идентификации собственно профессионального медицинского правонарушения. Законодательные установления и доктринальные источники, характеризующие медицинские правонарушения, оторваны от действительности клинической медицины. Для определения, измерения и оценки медицинского правонарушения не выработано не только специальных, но и даже просто приемлемых критериев, показателей и индикаторов. Правовые нормы не выверяются по практике медицинской деятельности с биологией здоровья притом, что несоответствие или противоречие законов государства законам природы бессмысленно. Необходим консенсус, нужна согласованность, гармония правил медицины и норм права – и в законотворчестве, и в правоприменении, что невозможно без преодоления комплекса приведенных упущений.

Knowledge and absorption capacity for innovation process in the aquaculture sector: A case study in the Mezquital Valley-Mexico
Authors: López-Meza Evelia , Terán-Bustamante Antonia , Leyva-Hernández Sandra Nelly
Published: November 2024

As the population’s demand for food continues to increase, aquaculture is positioned as a productive activity that provides high-quality protein. Aquaculture activity is characterized by its socio-economic impact, the generation of jobs, its contribution to food, and constant growth worldwide. However, in the face of threats of competition, producers must quickly adapt to market needs and innovate. Given this, this research aims to analyze the impact of the knowledge absorption capacity with the adoption of innovations by aquaculture producers in the Mezquital Valley in Hidalgo, Mexico. The methodological strategy was carried out through structural equation modeling using partial least squares and correlation tests. The findings show that knowledge absorption capacities explain 77.8% of the innovations carried out in aquaculture farms. Both variables maintain a medium-high correlation; the more significant the absorption capacity, the greater the innovation.
Optimizing the Signal-to-Noise Ratio using the Virtual Line of Sight and choosing the appropriate dimension
Authors: Qeryaqos Bushra Jarjees , Ayoob Saad Ahmed
Published: November 2024

One potential candidate technology for Beyond 5G (B5G) networks is the reconfigurable intelligent surface (RIS), which is easy to install on existing infrastructure such as vehicles and buildings. Creating additional paths between the transmitter and receiver to improve the received signal accessible to the system is one of the significant uses of RIS. A virtual line of sight (VLOS) is established through the Tx-RIS-Rx link without the line of sight (LOS). RIS technology solves the problem of low coverage in millimeter-wave communications. This paper presents the effect of the signal-to-noise ratio by changing dimensions. In addition to finding the optimal values for the dimensions that give the optimal SNR, simulation results prove that the RIS height is greater than or equal to half the dimension between the sender and the receiver. It is recommended that the RIS height be greater than half the distance between the sender and the receiver.
Efficient Pruned-DFT FBMC-OQAM for Performance Enhancement of MIMO Channel Equalization Techniques
Authors: Jamel Thamer M. , Al-Shuwaili Ali
Published: November 2024

A The next generation of wireless systems, like 5G/6G, ought to accommodate a wide range of potential use cases like massive real-time and machine-type communications. Accordingly, such systems need to provide high throughput, low latency, and a low peak to average power ratio (PAPR). It is not feasible to fulfil each of these needs with a single 5G/6G technique. On one hand, MIMO technique can potentially improve spectral efficiency and hence support more date rates. On the other hand, the utilization of multi-carriers’ techniques like FBMC/OQAM, or offset quadrature amplitude modulation, offers a compelling substitute for the traditional cyclic prefix-based orthogonal frequency division multiplexing (CP-OFDM) because of its excellent spectral efficiency and extremely low out-of-band radiation. However, the FBMC/OQAM orthogonality constraint is loosened, confined to the real field alone, resulting in intrinsic interference. This interference causes incompatibilities between FBMC/OQAM and certain MIMO schemes. Also, equalizing the time-varying MIMO channel is even more difficult when the complex valued symbol—which includes both real and imaginary FBMC/OQAM task, primarily due to the general non-flatness of the subchannels. From this perspective, we first suggest in this paper an efficient pruned-DFT-based implementation of MIMO to restoring the complex orthogonality and also reduce the complexity of the whole system. Then, we optimize MIMO channel equalization by efficiently separating and equalizing multiple parallel channels using various equalization techniques. The numerical results, presented as MSE versus subcarrier index, show that Pruned DFT technique consistently achieves lower MSE values compared to the standard MIMO FBMC-OQAM across various configurations, which indicates better error performance and its robustness in dynamic channel conditions.

Published: November 2024

The Internet of Things has rapidly grown in the past years as emerging technology. Moreover, 5G networks start to offer communication infrastructure for applications of the Industrial Internet of Things (IIoT). However, due to energy limitations of IIoT devices and heterogeneity of 5G networks, managing IIoT networks is a challenging task. One of the most critical issues in IIoT that requires consideration is traffic routing that has a significant impact on energy consumption, and thus, lifetime of the network. Artificial Intelligence (AI) has been widely employed to solve complex scientific and practical problems. Such AI techniques as neural networks, fuzzy systems, genetic algorithms are commonly employed in wireless networks to promote their optimization, prediction, and management. This study suggests using an Adaptive Neuro-fuzzy Inference System (ANFIS) in 5G networks of IIoT for improving the routing process. A flow-chat of routing protocol was suggested. For input and output values of the ANFIS linguistic variables, terms and membership functions were defined. A rules base was developed. To improve the rule base of the ANFIS, a genetic algorithm was proposed. The operation of ANFIS was simulated in Matlab software.

Furthermore, this study conducted an optimization analysis on the SDWAN (Software Defined Wide Area Network) network, SDWAN functions as a firewall that can provide connectivity support and infrastructure network development in branch offices with system security in one centralized platform. The test method used in this study is a connectivity test from each remote fortigate located in the branch office. While the analysis method used is Quality of Service (QoS), which is a method to find out data delivery (Packet Loss, Delay and Jitter) using the FortiManager application, which is the analytical and experimental proof of concept of the SDWAN network model using the BGP method for auto failover testing.
Advanced design and analysis of dual element MIMO antenna for Ultra-Wideband Applications
Authors: Ramamohan B , Prasad M Siva Ganga
Published: November 2024

This investigation uses the Genetic Optimization Method to convert a wide-band MIMO antenna into a UWB (3.1GHz–10.6 GHz) MIMO antenna. Initially, a 22 × 42, mm2 wideband 2X2 MIMO antenna was designed using commercial Flame Retardant-4 material. The structure of the antenna patch was designed using half-circular forms on the half-ground plane. The designed MIMO antenna operates throughout a large frequency range of 4.8–9.8 GHz. While it was successful in achieving broad band characteristics, this MIMO antenna was unable to reach ultra-wide band characteristics. The MIMO antenna was operated in UWB ranges by a parametric study, which indicated that the resonating characteristics can be significantly modified by inserting a rectangular slot into the ground plane. Throughout the operational range, it was important to be concerned about improved gain and good isolation. Accordingly, optimization was carried out in order to accomplish the essential, multi-objective goals. The difficult multi-objective design goal is now reduced to an optimization challenge by means of genetic algorithm based random search. One of the performance goals that this optimization strategy aimed to fulfil was an increase in isolation to –20 dB across the entire Ultra-Wideband, with S11 being below –10 dB from 3.1 to 10.6 GHz. It is recommended to randomly select the parameters from their respective ranges for this work. This led to the selection of an optimizer based on random searches. In the operating range, the UWB has a respectable gain of 4 dB to 6 dB and increased isolation to –20 dB, according to the genetic algorithm optimizer’s execution of the predefined multiple-objective task.
Effect of the illuminance meter used on the results of color light pollution measurements
Authors: Tabaka Przemysław , Wtorkiewicz Justyna
Published: November 2024

The paper presents the results of measurements of illuminance. Twenty-two types of illuminance meter with known spectral sensitivity curves of photometric heads and eleven lamps emitting colored light were used. Laboratory measurements were conducted at a characteristic point, with a focus on assessing intrusive light, with a value of 3 lx. The considerations were supplemented with simulated illuminance calculations. For most illuminance meters, correlations were observed between the measurement results and the calculations. This allows the conclusion that, especially in the case of colored light, one of the main factors affecting the measurement result is the spectral sensitivity curve of the photometric head. The greatest discrepancies in the obtained illuminance values were found in the case of lamps emitting blue light. The paper highlights the fact that measuring low illuminance values produced by lamps emitting colored light is not an easy task. Depending on the illuminance meter used, conclusions regarding the assessment of intrusive light may vary. The aim of the paper is to indicate that not all calibrated illuminance meters are suitable for this assessment.

In this paper, we compare behaviors of two possible descriptions of the sampled signal in the case when the sampling period tends to zero, but remains all the time greater than zero. Note that this is the case we are dealing with in analog-to-digital conversion in microwave photonic systems. From this comparison, it follows that the description with the weighted step function is superior to the description with the weighted Dirac comb. A couple of useful comments and remarks associated with the results presented are also provided in the context of microwave photonic systems.
Crowdsourcing Evaluation of Video Summarization Algorithm

The technique of video summarizing involves selecting the most relevant and informative sections of a video to generate its shortened and faster version. Crowdsourcing is a relatively new term that has been exploited in the present study to achieve video summarization. This technique helps in dividing a task into multiple parts, and each of these parts is then evaluated using a large group of individuals to solve problems that are otherwise difficult to solve using traditional computational machines. In this study, we offer a crowdsourcing subjective experiment in which summaries of processed video sequences are evaluated. Thus, we are proposing an experiment that utilizes crowdsourcing to evaluate the efficacy of an algorithm that summarizes videos. A group of 45 individuals participated in the experiment, where each of them were asked to watch 24 videos, each of 30-second and 45-second duration. An experimental comparison was conducted with respect to presentation order and random selection methods. A content-based video segmentation was also used to represent different levels of complexities and visual richness. The findings of the assessment showed that specific characteristics of a video such as its length, complexity, and content, play a major role in improving the performance of the summarization algorithm. This study is an essential step toward the development of video summarizing systems that are both more accurate and more efficient.

Introduction

Invisalign, introduced by Align Technology, Inc. in 1997, is a system of clear plastic aligners that provides aesthetic orthodontic treatment plus treatment customisation. Created using impressions or intraoral digital scans, patients wear and sequentially exchange removable, 0.75 mm thick polyurethane appliances. The aligners improve smile appearance, correct dentoalveolar posterior crossbites, increase arch length, relieve crowding, and provide more space for tooth alignment. Dentoalveolar expansion is a preferred alternative to interproximal tooth reduction when treating a patient using the Invisalign clear appliance.

Materials and methods

The present review systematically searched electronic databases for prospective and retrospective studies on dentoalveolar expansion using clear aligner therapy in human subjects. The quality of the studies was assessed using the revised Cochrane risk of bias tool.

Results

A high risk of bias was noted in the systematic evaluation of five human trials comprising 254 healthy individuals. The most frequent cause of bias was found to be patient selection. Patient attrition was caused by age-related issues, inadequate compliance, and the lack of blinded outcome evaluation, underscoring the need for better research protocols.

Conclusion

The present study examined maxillary arch expansion in adult patients who received clear aligner therapy. It was found that the efficiency of expansion at the completion of an aligner treatment sequence may be marginally better than at the completion of an expansion treatment due to the hysteresis (the difference between the predicted and actual results of expansion) of Invisalign appliances, which enhances effectiveness and generates the greatest expansion in the first and second premolar region.
Impact of climate change on agriculture in Poland
Authors: Faber Antoni , Jarosz Zuzanna
Published: November 2024

Agriculture, on the one hand, emits greenhouse gases which contribute to climate change, and on the other hand, it is the sector which is most affected by the progressing climate change. The aim of the study was to assess the impact of climate change on agriculture and to identify measures adapting agriculture in Poland to changing climatic conditions. The sources of information were legal acts, reports and documents of international institutions, as well as literature on the subject. The study analysed the impact of climate change effects on the conditions of conducting and the volume of agricultural production in global, European and national terms. The analysis showed that progressive climate change and its impact on changing agricultural production conditions threaten the productivity of agriculture, and thus limit the provision of food security. The dynamics of these changes, the extensive scope of threats and the strength of their negative impact prompt adaptation measures. Adaptation measures, the implementation of which enables adaptation to the current and expected climate and its impacts, have been identified.
Effect of different doses of apple pomace to the substrate on photosynthetic efficiency and yield in common buckwheat in a model experiment
Authors: Różewicz Marcin
Published: November 2024

By-products of apple juice pressing should be used for the benefit of the environment. One way to manage them is to add them to the soil in raw or composted form as a natural fertiliser and source of organic matter. A study was therefore undertaken to test several doses of apple pomace to the substrat on photosynthetic parameters and yield of buckwheat. The experiment was conducted in a vegetation hall under controlled, automatic irrigation to 60% of the field water capacity. The model study used the cultivar Red corolla and three doses of apple pomace applied to pots in the following amounts: 0 control, 70, 140 and 210 g per pot, which corresponded to field volume: 1, 2 and 3 t·ha−1. Four photosynthetic parameters (Pn, E, Gs and Ci) were measured and the water use efficiency was determined. Chlorophyll fluorescence (Fv/Fm and PI) was also investigated. The most suitable variant for buckwheat was the using 210 g which resulted in increased photosynthesis intensity, chlorophyll fluorescence and buckwheat yield.

Evaluation of occupational exposure to flour dust and additives in a milling industry
Authors: Matos Maria Luísa , Cardoso Ricardo
Published: November 2024

This study aimed to assess an environmental risk in a workstation: the occupational exposure of workers to flour dust, and mixtures of flour dust with additives in the cereal milling industry. The purpose was to understand how exposure to flour dust, and mixtures of flour dust with additives affects the health of workers. In the facilities of the milling company where this study was carried out, there is an area where workers are particularly exposed to flour dust and mixtures of flour dust with additives involved. Therefore, one of the main objectives of this study was to evaluate if these workers were subjected to occupational health hazards during their working hours, due to the contact with suspended flour dust in their workstations, focusing special attention to this area, whenever possible. A sampling of particles suspended in the air was carried out, in order to perform a quantitative analysis. Suction pumps were used, placed on workers, who work in three different workstations, to make a quantitative comparison. An average concentration (a.c.) of 17.27 mg/m3 was obtained in the workstation of the preparation of mixtures, an a. c. of 1.35 mg/m3 and one of 2.25 mg/m3 in the bagging workstation – for plain flour and for added flour, respectively. It was found that all values obtained exceed the Exposure Limit Value proposed by the Standard NP 1796:2014, which presents a value calculated as a weighted average of 0.5 mg/m3. Mitigation with the use of personal protective equipment (PPE), FFP3 type masks, is enough to protect workers.
