Understanding the Citizen’s Role in the Transition to a Smart Energy System: Are We Ready?
Authors: Biresselioglu Mehmet Efe , Demir Muhittin Hakan , Altinci Sebnem
Published: May 2022

Energy transition is one of the main pillars of the European Union’s climate change strategy suite. The policies set forth by European Union members to support energy transition are transposed into national policies, strategies, and action plans. Energy transition calls for empowering citizens and communities regarding energy-related initiatives. Of particular importance are smart energy systems and their potential for involving individuals and communities in energy transition initiatives. However, not all citizens are willing to invest in renewable energy or smart appliances. Thus, there is a need for implementing smart energy initiatives, which have three main steps, namely, awareness, mindset (readiness for action), and action. Bearing in mind the lack of uniformity in this area across the European Union, this manuscript assesses the levels of awareness, mindset, and action utilizing the results of a comprehensive international survey, the ECHOES project, with respect to demographic and socioeconomic variables, such as age, income level, and education level. The analysis reveals that 58% of respondents from the West European sample demonstrate a high level of awareness, 56% are ready for action, and 63% already demonstrate action. The percentages are similar for the East European sample, with 56% demonstrating a high level of awareness, 55% are ready for action, and 66% already demonstrating action. Overall, women have higher levels of awareness, readiness for action, and action. For both Western and Eastern European countries, education level and income level are important factors for smart energy adoption, with education levels proving to be more significant for East European countries.
New Results and Open Questions for SIR-PH Epidemic Models with Linear Birth Rate, Loss of Immunity, Vaccination, and Disease and Vaccination Fatalities
Authors: Avram Florin , Adenane Rim , Halanay Andrei
Published: May 2022

Our paper presents three new classes of models: SIR-PH, SIR-PH-FA, and SIR-PH-IA, and states two problems we would like to solve about them. Recall that deterministic mathematical epidemiology has one basic general law, the “R0 alternative” of Van den Driessche and Watmough, which states that the local stability condition of the disease-free equilibrium may be expressed as R0<1, where R0 is the famous basic reproduction number, which also plays a major role in the theory of branching processes. The literature suggests that it is impossible to find general laws concerning the endemic points. However, it is quite common that 1. When R0>1, there exists a unique fixed endemic point, and 2. the endemic point is locally stable when R0>1. One would like to establish these properties for a large class of realistic epidemic models (and we do not include here epidemics without casualties). We have introduced recently a “simple” but broad class of “SIR-PH models” with varying populations, with the express purpose of establishing for these processes the two properties above. Since that seemed still hard, we have introduced a further class of “SIR-PH-FA” models, which may be interpreted as approximations for the SIR-PH models, and which include simpler models typically studied in the literature (with constant population, without loss of immunity, etc.). For this class, the first “endemic law” above is “almost established”, as explicit formulas for a unique endemic point are available, independently of the number of infectious compartments, and it only remains to check its belonging to the invariant domain. This may yet turn out to be always verified, but we have not been able to establish that. However, the second property, the sufficiency of R0>1 for the local stability of an endemic point, remains open even for SIR-PH-FA models, despite the numerous particular cases in which it was checked to hold (via Routh–Hurwitz time-onerous computations, or Lyapunov functions). The goal of our paper is to draw attention to the two open problems above, for the SIR-PH and SIR-PH-FA, and also for a second, more refined “intermediate approximation” SIR-PH-IA. We illustrate the current status-quo by presenting new results on a generalization of the SAIRS epidemic model.
Continuous Emotion Recognition for Long-Term Behavior Modeling through Recurrent Neural Networks

Published: May 2022

One’s internal state is mainly communicated through nonverbal cues, such as facial expressions, gestures and tone of voice, which in turn shape the corresponding emotional state. Hence, emotions can be effectively used, in the long term, to form an opinion of an individual’s overall personality. The latter can be capitalized on in many human–robot interaction (HRI) scenarios, such as in the case of an assisted-living robotic platform, where a human’s mood may entail the adaptation of a robot’s actions. To that end, we introduce a novel approach that gradually maps and learns the personality of a human, by conceiving and tracking the individual’s emotional variations throughout their interaction. The proposed system extracts the facial landmarks of the subject, which are used to train a suitably designed deep recurrent neural network architecture. The above architecture is responsible for estimating the two continuous coefficients of emotion, i.e., arousal and valence, following the broadly known Russell’s model. Finally, a user-friendly dashboard is created, presenting both the momentary and the long-term fluctuations of a subject’s emotional state. Therefore, we propose a handy tool for HRI scenarios, where robot’s activity adaptation is needed for enhanced interaction performance and safety.

Published: May 2022

This study aims to determine the correlation between the mean value of bone density measured on the CBCT device and the primary stability of dental implants determined by resonant frequency analysis. An experimental study was conducted on a material of animal origin: bovine femur and pig ribs. Two types of implants were used in this study: self-tapping and non-self-tapping of the same dimensions. Results of the experimental study showed a statistically significant correlation between bone density expressed in HU units and the primary stability of self-tapping and non-self- tapping dental implants expressed in ISQ units in bovine femur bones and self-tapping implants and pig rib bones. There was no statistically significant correlation between non-self-tapping dental implants in pig rib bones. Self-tapping and non-self-tapping implants did not show statistical significance in the primary stability in bones of different qualities. The analysis of bone density from CBCT images in the software of the apparatus expressed in HU units can be used to predict the degree of primary stability of self-tapping and non-self-tapping dental implants in bones of densities D1 and D2, and self-tapping dental implants in bones of the lower quality D4.

Published: May 2022

Oil-contaminated soil is a major societal problem for humans and the environment. In this study, the pyrolysis method was applied to oil-contaminated soil used as a landfill and gas station site in Korea. The removal efficiency of the main components of oil-contaminated soils, such as total petroleum hydrocarbons (TPH), polyaromatic hydrocarbons (PAHs), unresolved complex mixture (UCM), and alkylated PAHs (Alk-PAHs) were measured, and the effect of temperature, treatment time, and moisture content on pyrolysis efficiency was studied. In order to evaluate the risk of soil from which pollutants were removed through pyrolysis, integrated ecotoxicity was evaluated using Daphnia magna and Allivibrio fischeri. The chemical and biological measurements in this study include contaminants of emerging concerns (CECs). Results showed that the pyrolysis was more efficient with higher treatment temperatures, moisture content, and treatment times. In addition, toxicity was reduced by 99% after pyrolysis, and the degree of toxicity was evaluated more sensitively in Allivibrio fischeri than in Daphnia magna. This study shows that weathered oil-contaminated soil can be effectively treated in a relatively short time through pyrolysis, as well as provides information on efficient conditions and the assessment of ecotoxicity.

Published: May 2022

Clinical studies in glioblastoma and pancreatic carcinoma patients strongly support the further development of H-1 protoparvovirus (H-1PV)-based anticancer therapies. The identification of cellular factors involved in the H-1PV life cycle may provide the knowledge to improve H-1PV anticancer potential. Recently, we showed that sialylated laminins mediate H-1PV attachment at the cell membrane. In this study, we revealed that H-1PV also interacts at the cell surface with galectin-1 and uses this glycoprotein to enter cancer cells. Indeed, knockdown/out of LGALS1, the gene encoding galectin-1, strongly decreases the ability of H-1PV to infect and kill cancer cells. This ability is rescued by the re-introduction of LGALS1 into cancer cells. Pre-treatment with lactose, which is able to bind to galectins and modulate their cellular functions, decreased H-1PV infectivity in a dose dependent manner. In silico analysis reveals that LGALS1 is overexpressed in various tumours including glioblastoma and pancreatic carcinoma. We show by immunohistochemistry analysis of 122 glioblastoma biopsies that galectin-1 protein levels vary between tumours, with levels in recurrent glioblastoma higher than those in primary tumours or normal tissues. We also find a direct correlation between LGALS1 transcript levels and H-1PV oncolytic activity in 53 cancer cell lines from different tumour origins. Strikingly, the addition of purified galectin-1 sensitises poorly susceptible GBM cell lines to H-1PV killing activity by rescuing cell entry. Together, these findings demonstrate that galectin-1 is a crucial determinant of the H-1PV life cycle.

(1) Background: The present study aims to report the side effects of vaccination against coronavirus disease 2019 (COVID-19) among patients with multiple sclerosis (MS) who were being treated with disease-modifying therapies (DMTs) in Poland. (2) Methods: The study included 2261 patients with MS who were being treated with DMTs, and who were vaccinated against COVID-19 in 16 Polish MS centers. The data collected were demographic information, specific MS characteristics, current DMTs, type of vaccine, side effects after vaccination, time of side-effect symptom onset and resolution, applied treatment, relapse occurrence, and incidence of COVID-19 after vaccination. The results were presented using maximum likelihood estimates of the odds ratio, t-test, Pearson’s chi-squared test, Fisher’s exact p, and logistic regression. The statistical analyses were performed using STATA 15 software. (3) Of the 2261 sampled patients, 1862 (82.4%) were vaccinated with nucleoside-modified messenger RNA (mRNA) vaccines. Mild symptoms after immunization, often after the first dose, were reported in 70.6% of individuals. Symptoms included arm pain (47.5% after the first dose and 38.7% after the second dose), fever/chills/flu-like symptoms (17.1% after the first dose and 20.5% after the second dose), and fatigue (10.3% after the first dose and 11.3% after the second dose). Only one individual presented with severe side effects (pro-thrombotic complications) after vaccination. None of the DMTs in the presented cohort were predisposed to the development of side effects. Nine patients (0.4%) had a SARS-CoV-2 infection confirmed despite vaccination. (4) Conclusions: Vaccination against SARS-CoV-2 is safe for people with MS who are being treated with DMTs. Most adverse events following vaccination are mild and the acute relapse incidence is low.

Authors: Köchle Belinda Rose , Garijo-Toledo María Magdalena , Llobat Lola , Sansano-Maestre José
Published: May 2022

Toxocara spp. is one of the most common zoonotic geohelminths in the world. Its infections are associated with the accidental ingestion of contaminated soil and affecting, especially children. In this study, feces, and soil samples from 14 public parks in the city of Valencia were analyzed. The Telemann method and a modified version of a sieving technique were used to process feces and soil, respectively. None of the fecal samples and 10.9% of soil samples from five parks (35.7%) tested positive for the presence of Toxocara eggs. The most contaminated areas were the canine sanitary parks (30.8% of the samples), followed by socialization areas for dogs (9.7%); no positive samples were found at children’s playgrounds. Our results suggest that most pets in Valencia are periodically dewormed, although additional preventive measures should be applied, since the risk of infection exists probably due to the presence of stray dogs and feral cats.
A Cross-Layer Approach MAC/NET with Updated-GA (MNUG-CLA)-Based Routing Protocol for VANET Network
Authors: Abbas Ali Hashim , Ahmed Ahmed Jamal , Rashid Sami Abduljabbar
Published: May 2022

Nowadays, technology is developed rapidly in communication technology. Several new technologies have been introduced due to the evolution of wireless communication and this provided the way to communicate among vehicles, using a Vehicular Ad-Hoc Network (VANETs). Routing in VANETs becomes most challenging because of the huge mobility and dynamical topology changes, which lead to reduced efficiency in the network. The core idea of this network is to increase the efficiency during the process of the communication. The most suited routing protocol for VANETs is Geographic routing, for the reason that it provides higher scalability and low overheads. The major challenges in VANETs are the selection of best neighbor in dynamically changing VANET topology. Furthermore, to provide better QoS needful actions are essential. In this paper, we introduced a new MAC/NET with Updated Genetic Algorithm—A Cross Layer Approach, (MNUG-CLA) based on a MAC layer and network layer to overcome the drawbacks of the network. In the network layer, a new neighbor discovery protocol is developed to select the best next hop for the dynamically varying network. In the MAC layer, in order to improve the quality, multi-channel MAC model is introduced for instantaneous transmission from various service channels. For overall optimal path selection, we used an updated GA algorithm. The performance was demonstrated through the use of an extensive simulation environment, NS-2. The simulation results prove that this protocol provides better results, in terms of energy efficiency, energy consumption and successive packet transmission, when compared with the earlier approaches.
Wind Loading of Photovoltaic Panels Installed on Hip Roofs of Rectangular and L-Shaped Low-Rise Buildings
Authors: Uematsu Yasushi , Yambe Tetsuo , Yamamoto Atsushi
Published: May 2022

Many residential houses in Japan have hip roofs with pitches ranging from 20° to 30°. Recently, roof-mounted photovoltaic (PV) panels have become popular all over the world for environmental conservation. The design of PV systems in Japan is usually based on the Japanese Industrial Standard (JIS) C 8955 (2017). However, the standard does not provide wind force coefficients for PV panels installed near roof edges (up to 0.3 m from the edge) because flow separation at the roof edges causes large up-lift forces on such panels. In this paper, we investigated the wind force coefficients for designing PV panels installed on hip roofs of rectangular and L-shaped low-rise buildings. The roof pitch was set to 25° as a typical value. Rectangular panels were installed almost over the whole roof, including the edge zones. Because the thickness of PV panels and the distance between PV panels and the roof are both as small as several centimeters, it is difficult to make wind tunnel models of PV systems with the same geometric scale as that for buildings. We focused on a numerical simulation using the unsteady Bernoulli equation to estimate the pressures in the space between PV panels and the roof. In the simulation, we used the time histories of wind pressure coefficients on the bare roof, which were measured in a turbulent boundary layer. We propose installing PV panels with small gaps between them along their short sides. The gaps may reduce the wind loads not only on the PV panels but also on the roofing due to pressure equalization. We discuss the optimum gap width from the viewpoint of wind load reduction.
Increasingly Dense and Connected Field: A Longitudinal Co-word Analysis of Youth Sociological Articles from 1990 to 2019
Authors: Obreja Dragoș M.
Published: May 2022

Youth studies represent a research field with visible potential, and its emergence has seen a substantial increase in the last decade. A longitudinal bibliometric analysis of sociological articles on youth was conducted using Web of Science (WoS) entries, with the analysis divided into three distinct decades, 1990–2019. From 41 sociological articles containing the keyword “youth” in 1990 to 704 in 2019, this evolution is reflected in the increasing interconnectedness of keyword co-occurrences. Thus, after 2000, keywords such as gender, adolescence, education, and race became increasingly popular, while keywords such as children and family structure, which were popular between 1990 and 1999, subsequently lost their relevance. The thematic cluster analysis reveals the emergence of new clusters, such as those centered around social media, LGBTQ, or mental health. The growth of occurrences for many keywords demonstrates the complex and heterogeneous development of the youth studies field in the sociological literature, so many future trends in this field remain unpredictable but promising at this time.
SOCIAL READINESS TO ACCEPT AND RECEIVE CREATIVITY
Authors: Banit O. , Franc M.
Published: May 2022

Creativity is understood as an activity that leads to the creation of something different from existing things or something that did not exist before. Creativity, as a term, changes its meaning depending on the distribution of axiological accents, in particular, whether the value belongs to the sphere of absolute, selfless, or utilitarian values.

Creativity is a conceptual work because it requires deep thinking, concentration and reliability. It is not accidental enlightenment, the uncontrolled work of the mind, although may be derived from it. This is hard, purposeful work that requires diligence, perseverance, and dedication. If this is not enough, no talent, ingenuity or knowledge will be enough.

The issue of social preparation for the perception of creativity and readiness to understand it is considered in the article. The author presents three levels of readiness to perceive and understand creativity. On the one hand, we can assume that modern society is ready to accept creativity as creativity is the need and necessity of our time. Creativity is the driving force of development, creativity elevates man, making it a phenomenon among living beings, modern man is aware of the impact of creativity on personal development. On the other hand, there is certain relativity of social readiness to accept creativity, as the understanding of creativity and ease of its implementation depends on individual groups, social environment, level of awareness of creativity of people belonging to these groups, the result of the conflict of conformism and nonconformism, in general. There is the third side. Modern society is not ready to fully experience the phenomenon of creativity, as mass culture has lowered everyday life to the level of pseudo-art, promoting delusion and illusion, glorifying superficiality and greed of fast life, turning creativity into a mechanism of consumption.

Эксплуатационная надежность и долговечность объектов строительства зависит от качества последовательно выполняемых технологических операций. Испытание грунтов - достаточно ответственный технологический процесс при устройстве основания под фундаменты, учитывая, что именно способность основания не деформируясь выдерживать нагрузки от здания определяет надежность функционирования зданий и сооружений на протяжении всего жизненного цикла. В работе представлены результаты испытаний грунтов для определения максимальной плотности, оптимальной влажности и вида грунта. Проведенные исследования показали, что грунты, используемые для создания искусственного основания, необходимо подбирать с таким расчетом, чтобы обеспечить легкую трамбуемость и укатываемость, создавая при этом плотный и непроницаемый слой без образования пустот и впадин.

The operational reliability and durability of construction objects depends on the quality of sequentially performed technological operations. Soil testing is a rather important technological process when constructing a foundation for foundations, given that it is the ability of the foundation to withstand the loads from the building without deforming that determines the reliability of the functioning of buildings and structures throughout the entire life cycle.The paper presents the results of soil tests to determine the maximum density, optimal moisture content and type of soil. The conducted studies have shown that the soils used to create an artificial foundation must be selected in such a way as to ensure easy compaction and rolling, while creating a dense and impermeable layer without the formation of voids and depressions.

Hip dysplasia, associated with this syndrome, is frequent but poorly studied. Objective: To describe the radiographic alterations of the hip in patients with Congenital Zika Syndrome (CZS). Methods: Observational cross-sectional cohort study. We studied 25 patients with a serological diagnosis of CZS and a sample of 50 hips. Patients underwent evaluation, with lines and angles drawn on AP and P radiographs of the pelvis to assess the relationship between the femoral head and the acetabulum. The correlation was performed between radiographic changes of the hip in patients with SZC, gender, presence of arthrogryposis, spasticity, and microcephaly. Results: The mean age was 36 months (29-45 months), 15 patients were female (60%), with a predominance of blacks and browns (72%). The mean maternal age was 28 years (16-44 years), 11 (44%) had the disease before the 12th week of gestation, and all had clinical symptoms related to ZIKA virus infection. At birth, patients had an average head circumference of 26 cm (26-32 cm). Of the 50 hips evaluated in the study, 38 (76%) hips patients had orthopedic deformities, and 20 (40%) hips patients had arthrogryposis. In the radiographic changes of the hip, of the 50 hips, 12 (24%) hips were Tonnis grade I, 22 (44%) were subluxated (grade II), 9 (18%) were low dislocated (grade III), and 7 (14%) were high dislocated (grade IV). The RI was changed in 43 (86%) hips. ACD was valgus in 45 (90%) hips. ACEW was changed in 13 (26%) hips. The IA was changed in 18 (36%) of the evaluated hips. Conclusion: We found a high frequency of dysplastic changes in the hip in the patients of this study. So, we indicate radiological investigation of the hip in children with microcephaly and suspected CZS.

Waste-to-Energy (WtE) has been considered as an option to eliminate Krabi’s problems of municipal solid waste (MSW) management. A survey on WtE potential as well as key drivers, barriers, and challenges to overcome the barriers was conducted in this study. The study found high WtE potential due to huge amount of many years accumulated MSW in couple with the increasing trend of new daily waste generation. Meanwhile, Krabi is an island having land limitation for landfill. The urgent need to eliminate the huge amount of MSW has become a key driver for WtE implementation. One more key driver of WtE is Krabi Goes Green roadmap with target to generate electricity from 100% renewable energy by the year 2026. Another key driver is disruptive effects of MSW management roadmap under Section 44 of Thailand's Constitution 2017. By the way, implementation of WtE is facing with public opposing due to concerning of dioxin and air pollutant emissions from solid waste combustion. How to ensure zero emission of dioxin and air pollutants is very challenging to achieve public trust and acceptance. High temperature combustion as well as installation of high efficiency end-of-pipe treatment together with real-time monitoring system was recommended by some interviewees of the present study. In addition, due to MSW management and WtE power plant investment must involve with many organizations; therefore, stakeholders' open mind consultation and policy integration among relevant governmental agencies are highly recommended.

Consumption of fruit and vegetables in Indonesia is still low. One way to increase fruit consumption is the use of sliced fruit in snack boxes. The preparation of sliced fruit in snack boxes has not been carried out because the durability of cut fruit is very short due to the fruit's physiological characteristics, which is still doing respiration and the presence of enzymatic activity that causes browning. The blanching process can do enzymatic reaction inhibition. This study aims to determine the shelf life of sliced pepaya fruit using the hot water blanching method using ascorbic acid and sodium benzoate immersion. This study used a randomized block design with 1 factor, namely the addition of anti-browning agents in the form of 1% ascorbic acid and 1% sodium benzoate. Storage was carried out for seven days, and parameter observations were carried out on days 0, 1, 3, 5, and 7. The parameters observed were moisture content, vitamin C, pH, texture, and sensory tests (color, aroma, texture, taste, and overall preference). The results showed a decrease in moisture content, vitamin C, pH, and texture of sliced pepaya fruit during storage in all treatments. Blanching by immersion using ascorbic acid can increase vitamin C levels and decrease the pH value of sliced pepaya during storage. Immersion with ascorbic acid and Na benzoate not affected on sliced pepaya’s texture during storage. Sensory testing showed that the immersion of ascorbic acid and Na benzoate could maintain the color, aroma, taste, and overall preference of the panelists for sliced pepaya during storage.

Yoghurt is a dairy product from the second fermentation of Lactic Acid Bacteria (LAB) as a starter, namely Streptococcus thermophilus and Lactobacillus bulgaricus which live in symbiosis. Lactic acid bacteria are bacteria that are capable of producing lactic acid, hydrogen peroxide, antimicrobials and other metabolic products that have a positive effect on health and the body at low environmental pH. Red dragon fruit (Hylocereus polyrhizus) contains higher levels of vitamin C, vitamin B3 (niacin), fiber and betacyanin than white dragon fruit. Dragon fruit skin which weighs 30-35% of the weight of the fruit has not been widely used by the general public and is only disposed of as garbage, thereby increasing environmental pollution. This study aims to determine the proportion of addition of dragon fruit peel extract and brown sugar to the best chemical, physical, and organoleptic quality in yogurt. The method used in this research is a factorial randomized block design (RAK) consisting of 2 factors, namely the proportion of addition of red dragon fruit peel extract (50 grams and 70 grams) and the addition of brown sugar (15 grams, 25 grams, and 35 grams). Each treatment was repeated 3 times to obtain 18 trials. The best research results on yogurt on chemical, physical, and organoleptic content were found in the B2G3 treatment (Addition of 70 grams of dragon fruit peel extract and 35 grams of brown sugar) with a protein value of 0.37%, viscosity 2.00 Pa.s, reducing sugar 4 .16 (mg/g), color with a value of 3.8 (like), aroma with a value of 3.4 (somewhat like), texture with a value of 3.1 (somewhat like), and taste with a value of 3.96 (like) .
