Published: December 2020

During physical exercise, the absorbed dose of air pollutants increases. Acute effects of exposure to air pollutants during exercise in healthy young adults remain poorly documented. The aim of this study was to assess the acute responses in fractionated exhaled nitric oxide (FeNO) and blood pressure to air pollution exposure during exercise in young adults with different physical activity levels (low or high). In this study, 76 healthy university students participating in physical activity classes (low level of physical activity) and attending sports training (high level of physical activity) completed two indoor exercise trials when air pollutant concentrations were high (exposure trial) and when the quality of the air was good (control trial). We monitored indoor particulate matter with diameter <10 µm and <2.5 µm (PM10 and PM2.5) and outdoor PM10, nitric oxides (NO2, NOx, NO), and sulfur dioxide (SO2) concentrations. Systolic and diastolic blood pressure (SBP and DBP), heart rate (HR), oxygen saturation (SpO2), and FeNO were measured at baseline and after 45–60 min of physical activity. There were no significant differences between physiological responses to training performed under different exposure conditions in blood pressure, HR, and SpO2. Significant positive correlations between post-exercise ΔFeNO during exposure trials and ambient air pollutants were found. FeNO increase during the exposure trial was associated with a higher physical activity level and higher outdoor PM10 and NO2 concentrations. In young and healthy adults, some differences in physiological responses to physical activity between polluted and control environments could be observed. Participants with a high physical activity level were more likely to have an increase in FeNO after exercise in a polluted environment but not after the control exercise trials.

Published: December 2020

The school neighbourhood built environment (BE) can facilitate active transport to school (ATS) in adolescents. Most previous studies examining ATS were conducted in large urban centres and focused on BE of home neighbourhoods. This study examined correlations between school-level ATS rates among adolescents, objectively measured school neighbourhood BE features, and adolescents’ perceptions of the school route across different urbanisation settings. Adolescents (n = 1260; 15.2 ± 1.4 years; 43.6% male) were recruited from 23 high schools located in large, medium, and small urban areas, and rural settings in Otago, New Zealand. Adolescents completed an online survey. School neighbourhood BE features were analysed using Geographic Information Systems. School neighbourhood intersection density, residential density and walkability index were higher in large urban areas compared to other urbanisation settings. School-level ATS rates (mean 38.1%; range: 27.8%–43.9%) were negatively correlated with school neighbourhood intersection density (r = −0.58), residential density (r = −0.60), and walkability index (r = −0.64; all p < 0.01). School-level ATS rates were also negatively associated with adolescents’ perceived safety concerns for walking (r = −0.76) and cycling (r = −0.78) to school, high traffic volume (r = −0.82), and presence of dangerous intersections (r = −0.75; all p < 0.01). Future initiatives to encourage ATS should focus on school neighbourhood BE features and minimise adolescents’ traffic safety related concerns.

Published: December 2020

As antiviral vaccines are still pending for the COVID-19 disease, improving dentists’ knowledge and prevention measures is important. This study aimed to assess dentists’ knowledge, attitude, and perception of COVID-19 in Saudi Arabia during the early outbreak period. In addition, infection control measures for dental setting were also assessed. Online questionnaire was distributed to dentists in different regions of Saudi Arabia when COVID-19 outbreak in Saudi Arabia was at its beginning. The questionnaire was assessing demographic variables, knowledge, attitude, risk perception, and preparedness towards COVID-19. Questions regarding infection control measures were also included. The correct incubation period of the virus was recognized by 43% of participants. Fever, cough, and shortness of breath were the mostly recognized symptoms for COVID-19 (98.9%, 95.5%, and 93.3% respectively). Participants in age groups ≥60, 50–59, and 20–29 years old were more likely to perceive COVID-19 as a very dangerous disease compared to 30–39 and 40–49 age groups. Dentists in Saudi Arabia showed satisfactory knowledge and positive attitude towards COVID-19. Improving dentists’ level of knowledge could be achieved through increasing their accessibility to materials provided by dental health care authorities, which specifies the best and safest approaches for dealing with patients during and after the outbreak.
Media and Misinformation in Times of COVID-19: How People Informed Themselves in the Days Following the Portuguese Declaration of the State of Emergency
Authors: Ferreira Gil Baptista , Borges Susana
Published: December 2020

This study takes as a starting point the importance and dependence of the media to obtain information about the pandemic. The dependency theory of the media system was developed in the 1970s when mass media were the dominant source of information. Today, at a time when media choices have become abundant, studies are needed to understand the phenomenon of media dependence in light of new dimensions made important by the transformations that have taken place in the social and media fields—where the coexistence of mass media with social media platforms stands out. As large-scale crises rarely occur and the media environment changes rapidly, it is important to analyze how media dependence relates to choose and trust in different media (traditional media vs. social media) in times of crisis. Several questions arise. What is the trust attributed by individuals to social media as sources of information about COVID-19? How well informed are the individuals who choose these sources as the main sources of information? From a questionnaire administered to 244 individuals in Portugal, during the first week of the state of emergency (March 2020), this research seeks to identify how people gained access to information about COVID-19, how they acted critically towards the various sources and how they assess the reliability of different media. Finally, it analyzes the association between the type of medium chosen and adherence to misinformation content about the virus. The results reveal the existence of a phenomenon of dependence on the media, with a strong exposure (both active and accidental) to informative content, with conventional media being privileged as the main source, and positively distinguished in terms of confidence. Finally, a statistically significant association of a positive sign was identified between the use of social media as the main source and the acceptance of misinformation.

Authors: Jiménez-García Mercedes , Ruiz-Chico José , Peña-Sánchez Antonio Rafael
Published: December 2020

Tourism and landscape are broad and complex scientific research fields, as is the synergy between them has given rise to a volume of articles diverse in nature, subject matter and methodology. These difficulties mean that, at present, there is no complete theoretical framework to support this tourism and landscape research, nor complete knowledge of its structure and organization. This motivates the present work, which constitutes the first attempt at mapping this research topic by applying bibliometric techniques using VOSviewer and Science Mapping Analysis Software Tool (SciMAT) software. A total of 3340 articles from journals indexed in Web of Science were analyzed. The results obtained confirm that interest in the study of these concepts has been growing, especially in the last decade. The main contribution of this work lies in the identification of work themes that were basic to the construction of the field but that are currently in decline, such as “cultural heritage” and other themes important to the field that should continue to be dealt with, such as “national parks” or “geotourism”. The transversal nature of sustainability that appears in the network of keywords related to currently emerging themes, such as “planning” and “environment”, is also highlighted and reinforced.

Published: December 2020

Solanum nigrum L., a hyperaccumulator of cadmium (Cd), is regarded as a promising candidate for phytoremediation of heavy metal pollution. In the present study, the hairy roots of Solanum nigrum L. were selected as a model plant system to study the potential application of Iron-regulated Transporter Gene (IRT1) for the efficient phytoremediation of Cd pollution. The transgenic hairy roots of Solanum nigrum L. expressing the IRT1 gene from Arabidopsis thaliana were successfully obtained via the Agrobacterium tumegaciens-mediated method. Expression of IRT1 reduced Cd stress-induced phytotoxic effects. Significantly superior root growth, increased antioxidant enzyme activities, decreased reactive oxygen species (ROS) levels, and less cell apoptosis were observed in the transgenic hairy roots of Solanum nigrum L. compared to the wild-type lines under Cd stress. Enhanced Cd accumulation was also carried out in the transgenic hairy roots compared to the control (886.8 μg/g vs. 745.0 μg/g). These results provide an important understanding of the Cd tolerance mechanism of transgenic IRT1 hairy roots of Solanum nigrum L., and are of particular importance to the development of a transgenic candidate for efficient phytoremediation process.

Background and objectives: Obesity presents as a multifactorial, pandemic disease that arises as a consequence of unequal energy intake and energy consumption. Obesity adversely affects the quality of life, leading not only to disability, but also to various other disorders. Bariatric surgery is the most effective method for achieving significant and sustained weight loss in individuals with extreme obesity. The aim of this study was to examine how well surgically induced weight loss is maintained after five years of follow-up and its effects on cardiovascular risk factors and outcome. Materials and Methods: This is a retrospective cross-sectional study of 66 patients with morbid obesity, with body mass index (BMI) ≥ 40 kg/m2 or BMI ≥ 35 kg/m2 and obesity-related health conditions, aged 20 to 61 years, mostly women (77.3%) who underwent laparoscopic Roux-en-Y gastric bypass surgery. Results: Average follow-up was 6.42 years (95% CI 6.30–6.54 years) after surgery, with survival rate of 97% in operated individuals. There was a statistically significant reduction of weight and body mass index 6 months and 5 years after surgery in comparison to the initial values (p < 0.001). Of 62 patients who presented weight loss at the end of the follow-up period, 38 were able to maintain the amount of weight loss that was attained 6 months after surgery, while 24 patients regained weight compared to their postoperative weight at 6 months. Two patients reported no weight loss after treatment. Significant weight reduction was associated with better control of diabetes and increased self-reported physical activity at 6 months and 5 years after surgery, as well as with a reduction of the use of anti-diabetic and anti-hypertensive medications. Conclusions: Our research demonstrates a positive long-term impact of bariatric surgery on patients’ health conditions, significant and sustained weight loss, and decrease in BMI, which were associated with a reduction of co-morbidities and risk factors for cardiovascular diseases.

Published: December 2020

The non-volatile memory (NVM) device is a useful way to solve the memory wall in computers. However, the current I/O software stack in operating systems becomes a performance bottleneck for applications based on NVM devices, especially for key–value stores. We analyzed the characteristics of key–value stores and NVM devices and designed a new embedded key–value store for an NVM device simulator named PMEKV. The embedded processor in NVM devices was used to manage key–value pairs to reduce the data transfer between NVM devices and key–value applications. Meanwhile, it also cut down the data copy between the user space and the kernel space in the operating system to alleviate the I/O software stacks on the efficiency of key–value stores. The architecture, data layout, management strategy, new interface and log strategy of PMEKV are given. Finally, a prototype of PMEKV was implemented based on PMEM. We used YCSB to test and compare it with Redis, MongDB, and Memcache. Meanwhile, the Redis for PMEM named PMEM-Redis and PMEM-KV were also used to test and compared with PMEKV. The results show that PMEKV had the advantage of throughput and adaptability compared with the current key–value stores.

Published: December 2020

Background: Adults frequently interpret food-associated adverse reactions as indicators of a food allergy. However, the public perception of food allergy may differ from a clinician’s point of view. The prevalence of patient-reported food allergy tends to be higher than physician-confirmed cases. Dermatological manifestations (urticaria, pruritus, dermatitis, and edema) are frequently reported by patients. Objective: The aim of this study was to describe patient-reported symptoms related to suspected food allergies and particularly to characterize and highlight the volume of patients who visit Budapest allergy clinics with suspected food allergies. Methods: In this prospective study, adult (≥18 years) patients were examined at the Allergology Outpatient Unit of the Dept. of Dermatology, Venereology, and Dermatooncology, Semmelweis University, Budapest. The examination included a detailed medical history; physical examination; and when necessary the measurement of allergen-specific serum immunoglobulin E (IgE) levels. Results: Data from 501 patients (393 women, 108 men) were analyzed. Intolerance to dietary biogenic amines occurred in 250 cases (250/501, 50%). Oral allergy syndrome was confirmed in 71 patients (71/501, 14%). Allergy to food preservatives was diagnosed in 14 (14/501, 3%) cases by a dermatologist-allergist specialist. Five individuals (5/501, 1%) were diagnosed with IgE-mediated food allergy. In some cases (28/501, 6%), edema-inducing/enhancing side effects of drugs were observed which patients had misattributed to various foods. Among the food groups considered to be provoking factors, the most frequently mentioned were fruits (198/501, 40%), milk/dairy products (174/501, 35%), and nuts/oilseeds (144/501, 29%). Overwhelmingly, urticaria (47%) was the most common dermatological diagnosis, followed by dermatitis (20%) and allergic contact dermatitis (8%). Conclusion: Improvement is needed in food allergy, food intolerance, and general nutritional knowledge among the general public. According to our data, perceived/self-reported food allergies were overestimated by adults when compared against physician-confirmed food allergies; however, other diseases potentially responsible for food-related problems were underestimated. The prevalence of oral allergy syndrome was high in the cohort. Intolerance to dietary biogenic amines was common, and although the role of dietary histamine and biogenic amine is not entirely understood in eliciting patients’ symptoms, improvements in complaints were reported during the control visits.

Published: December 2020

There is evidence in rodents to suggest that theacrine-based supplements modulate tissue sirtuin activity as well as other biological processes associated with aging. Herein, we examined if a theacrine-based supplement (termed NAD3) altered sirtuin activity in vitro while also affecting markers of mitochondrial biogenesis. The murine C2C12 myoblast cell line was used for experimentation. Following 7 days of differentiation, myotubes were treated with 0.45 mg/mL of NAD3 (containing ~2 mM theacrine) for 3 and 24 h (n = 6 treatment wells per time point). Relative to control (CTL)-treated cells, NAD3 treatments increased (p < 0.05) Sirt1 mRNA levels at 3 h, as well as global sirtuin activity at 3 and 24 h. Follow-up experiments comparing 24 h NAD3 or CTL treatments indicated that NAD3 increased nicotinamide phosphoribosyltransferase (NAMPT) and SIRT1 protein levels (p < 0.05). Cellular nicotinamide adenine dinucleotide (NAD+) levels were also elevated nearly two-fold after 24 h of NAD3 versus CTL treatments (p < 0.001). Markers of mitochondrial biogenesis were minimally affected. Although these data are limited to select biomarkers in vitro, these preliminary findings suggest that a theacrine-based supplement can modulate select biomarkers related to NAD+ biogenesis and sirtuin activity. However, these changes did not drive increases in mitochondrial biogenesis. While promising, these data are limited to a rodent cell line and human muscle biopsy studies are needed to validate and elucidate the significance of these findings.

Human milk fortification is a routine clinical practice for feeding preterm infants. We hypothesized that donkey milk can be a suitable basis for developing an innovative human milk fortifier. Our randomized controlled single-blind clinical trial, named “Fortilat”, evaluated the feeding tolerance, growth and clinical short-term outcomes in a population of preterm infants fed with a novel multi-component fortifier and a protein concentrate derived from donkey milk. The aim of the current study is to extend the previous findings and to evaluate the auxological outcomes of the infants enrolled in the “Fortilat” trial at 18 months of age. In the previous trial “Fortilat”, the fortification protocol followed was the same for the two groups, and the two diets were designed to be isoproteic and isocaloric. All infants enrolled in the trial were included in a premature infant developmental evaluation program consisting of hospital visits at 40 ± 1 weeks of postmenstrual age, and at 6, 12 and 18 months of corrected age. Weight, head circumference and length were expressed in z-score using neonatal Intergrowth21st and INeS charts at birth, and WHO 0–5 years growth charts at 18 months. 122 children (Bovine-arm = 62, Donkey-arm = 60) were included in this study. All the observations were recorded in the interval of 18 ± 3 months of the correct age. The two groups did not differ for head circumference, length or weight at 18 months of age. Our data show that fortifiers derived from donkey milk had not different long term auxological outcomes of standard bovine-derived fortifier, but the new donkey milk fortifier was well tolerated in our population.

Published: December 2020

Influenza virus has the potential for being one of the deadliest viruses, as we know from the pandemic’s history. The influenza virus, with a constantly mutating genome, is becoming resistant to existing antiviral drugs and vaccines. For that reason, there is an urgent need for developing new therapeutics and therapies. Despite the fact that a new generation of universal vaccines or anti-influenza drugs are being developed, the perfect remedy has still not been found. In this review, various strategies for using nanoparticles (NPs) to defeat influenza virus infections are presented. Several categories of NP applications are highlighted: NPs as immuno-inducing vaccines, NPs used in gene silencing approaches, bare NPs influencing influenza virus life cycle and the use of NPs for drug delivery. This rapidly growing field of anti-influenza methods based on nanotechnology is very promising. Although profound research must be conducted to fully understand and control the potential side effects of the new generation of antivirals, the presented and discussed studies show that nanotechnology methods can effectively induce the immune responses or inhibit influenza virus activity both in vitro and in vivo. Moreover, with its variety of modification possibilities, nanotechnology has great potential for applications and may be helpful not only in anti-influenza but also in the general antiviral approaches.

Published: December 2020

Determination of medical decision-making capacity (DMC) is one of the common encounters in Consultation-Liaison Psychiatry (CLP) services. It is a common misbelief that patients with “psych history” lack capacity more often than patients without mental illness. The study aims to examine the relationship between mental illness and DMC in patients presented to acute medical settings. The study is a retrospective chart review, where data were collected from the patients admitted to the medical units and assessed for capacity by a psychiatrist. Clinical and demographic characteristics were compared between two groups (patients having capacity and lacking capacity) using t-tests or chi-square tests, as appropriate. The commonest reason for DMC evaluation requests was for the patients who wanted to leave the hospital against medical advice. Overall, 53% (52/98) of the patients evaluated for DMC were found to lack capacity. Group of patients lacking DMC had a significantly higher percentage of males (58% vs. 35%) but were significantly less employed (8% vs. 10%). No significant difference was observed in other demographic characteristics and primary psychiatric diagnoses (past and current) among the two groups. However, patients lacking capacity were found to have a significantly more occurrence of current (48% vs. 11%) and past (23% vs. 4%) history of neurocognitive disorder, and larger trend significance (31% vs. 15%) of active psychiatric symptoms. We conclude that patients with neurocognitive disorders and active psychiatric symptoms might have poor DMC but not all patients who have psychiatric diagnoses lack medical DMC. Larger studies especially in outpatient psychiatric settings are suggested to derive more conclusive results.

Published: December 2020

A method of time-of-flight, small-angle neutron scattering (TOF-SANS) has been developed based on the iMATERIA powder diffractometer at BL20, of the Materials and Life Sciences Facility (MLF) at the high-intensity proton accelerator (J-PARC). A large-area detector for SANS, which is composed of triple-layered 3He tube detectors, has a hole at its center in order to release a direct beam behind and to detect ultra-small-angle scattering. As a result, the pulsed-neutron TOF method enables us to perform multiscale observations covering 0.003 < q (Å−1) < 40 (qmax/qmix = 1.3 × 104) and to determine the static structure factor S(q) and/or form factor P(q) under real-time and in-situ conditions. Our challenge, using unique sample accessories of a super-conducting magnet and polarized neutron, is dynamic nuclear polarization (DNP) for contrast variation, especially for industrial use. To reinforce conventional SANS measurements with powder materials, grazing-incidence small-angle neutron scattering (GISANS) or reflectivity is also available on the iMATERIA instrument.

Published: December 2020

The new severe acute respiratory syndrome coronavirus (SARS-CoV-2) has caused more than 40 million human infections since December 2019, when a cluster of unexplained pneumonia cases was first reported in Wuhan, China. Just a few days after the coronavirus was officially recognized, it was identified as the causative agent of this mysterious pneumonia. This paper discusses the pros and cons of antiviral drugs from the selective pressure and possible drug resistance point of view. We also address the key advantages of potential selective pressure-free treatment methods such as the use of sparsely and densely ionizing low-dose radiation (LDR). It is known that LDR has the capacity to modulate excessive inflammatory responses, regulate lymphocyte counts and control bacterial co-infections in patients with COVID-19 and different modalities. Substantial evidence shows that viruses are constantly mutating and evolving. When an antiviral immune response is unable to eliminate a virus, viral evolution is promoted. Therefore, it is of crucial importance to limit the use of antivirals/vaccines against SARS-CoV-2 when their effects on viral fitness are not fully understood. Furthermore, to limit the spread of the virus, it is essential to develop a vaccine that is available for as many people as possible. However, with the advent of vaccines or new therapies, the new situation may force the virus to evolve. Given this consideration, selective pressure-free treatments for COVID-19 are of great importance.

Published: December 2020

Machine learning and statistical approaches have transformed the management of infrastructure systems such as water, energy and modern transport networks. Artificial Intelligence-based solutions allow asset owners to predict future performance and optimize maintenance routines through the use of historic performance and real-time sensor data. The industrial adoption of such methods has been limited in the management of bridges within aging transport networks. Predictive maintenance at bridge network level is particularly complex due to the considerable level of heterogeneity encompassed across various bridge types and functions. This paper reviews some of the main approaches in bridge predictive maintenance modeling and outlines the challenges in their adaptation to the future network-wide management of bridges. Survival analysis techniques have been successfully applied to predict outcomes from a homogenous data set, such as bridge deck condition. This paper considers the complexities of European road networks in terms of bridge type, function and age to present a novel application of survival analysis based on sparse data obtained from visual inspections. This research is focused on analyzing existing inspection information to establish data foundations, which will pave the way for big data utilization, and inform on key performance indicators for future network-wide structural health monitoring.
Investigation of Students’ and Parents’ Perceptions of Authentic Contextual Learning at Home and Their Mutual Influence on Technological and Pedagogical Aspects of Learning under COVID-19
Authors: Hwang Wu-Yuin , Hariyanti Uun
Published: December 2020

During the COVID-19 pandemic, students have been forced to learn at home. Authentic contexts are essential to designing useful learning activities. Therefore, this study used mobile technology, namely Ubiquitous Geometry (UG), to merge authentic contexts into learning activities and investigate the influence of authentic contextual learning (ACL) on students’ and parents’ perceptions. This is because parents inevitably have an effect on students’ learning at home, which has not been clearly addressed in past studies. This study investigated students’ and parents’ perceptions in terms of technological and pedagogical aspects of the implementation of ACL supported by UG while learning at home. We conducted one experiment on 20 fifth-grade students and their parents. In the students’ acceptance model, the results indicated that students’ ease of use and usefulness significantly influenced their positive attitude toward ACL supported by UG, and the positive attitude also significantly influenced intention to continue using our proposed system in both the technological and pedagogical aspects. In the mutual influence between students’ and parents’ acceptance model, it was found that parents significantly influenced their children’s perceptions of ACL at home. In the mediation analysis, we found parents’ ease of use and intention to use could mediate the relation between students’ positive attitude and intention to use in the pedagogical aspect. From the interview, we found that parents thought that the learning activity in authentic contexts was useful and encouraged their children to do more engagement. However, in the technological aspect of the mutual influence between students’ and parents’ acceptance model, no mediation existed. This might be because parents worried their children were overusing mobile devices.

Festivals and events are important activities related to enhancing the image of the destination. Modern festivals are spread all over the world, not only changing the rhythm of daily life but also bringing more development possibilities for the places where these festivals are held. In order to learn more about tourists’ experiences in emerging events, a detailed study of famous hot air balloon festivals was conducted in Taitung City, Taiwan. Based on the stimulus-organism-response (S-O-R) model, the purpose of this study is to explore the relationship among these three constructs, namely stimulus: perception of marketing strategies and motivation, organism: positive emotions and satisfaction and response: revisit intention. Face-to-face surveys were conducted on-site in 2014 and 2018, a total of 896 valid questionnaires were collected from tourists who visited the Taiwan International Balloon Festival. SPSS Macros PROCESS was used to examine the measurement model. This study confirms the application of the S-O-R model in predicting tourists’ revisit intentions in the context of emerging events in the tourism industry. The survey results show that whether in 2014 or 2018, tourists’ satisfaction and tourists’ positive emotions can mediate the relationship between tourists’ perception of marketing strategies (or tourist’s motivation) and tourists’ revisit intention. Moreover, only in 2018, tourists’ visiting frequency can moderate the relationship between satisfaction and revisit intention.

Published: December 2020

In a new stage of booming platform economy, improving the employees’ job security is the key factor to ensure the sustainable development of a platform organization. Based on the cognitive behavior theory, this study introduces the perceived insider status as the moderator variable, and constructs the process mechanism model of job insecurity on employee engagement. The aim of this study is to examine the relationship between job insecurity, emotional response and employee engagement, and provide suggestions for reducing job insecurity and improving employee engagement. Using a 2-wave time-lagged survey data of 341 workers in China firms, data were collected with a self-report questionnaire and analyzed with the statistical package for the social science (AMOS, SPSS). The research result found a negative relationship between job insecurity and employee engagement, and that this negative relationship was mediated by negative emotion or positive emotion. Furthermore, perceived insider status moderated the relationship between job insecurity and positive emotion or negative emotion; the higher the perceived insider status is, the weaker the negative impact of job insecurity on positive emotion and the weaker the positive impact on negative emotion. The research results provide theoretical guidance for organizations to improve employee engagement and help to strengthen the importance of organizations to employees’ job insecurity.

Published: December 2020

Through Density Functional Theory (DFT), we have unveiled the atomic structures, adsorption characteristics and electronic structures of the poisonous and explosive vapor, m-dinitrobenzene (m-DNB), on pure, defective and various doped AlN nanosheets from a physical perspective. It is found that the adsorption energy, band gap change and sensitivity to the vapor are significantly increased through atomic-scale modification of the nanosheet. The AlN monolayer with Al-N divacancy has the largest adsorption energy and has potential to be utilized as adsorption or filtration materials for m-DNB vapor. The Si-doped AlN nanosheet possesses a much larger band gap change (−0.691 eV) than the pure nanosheet (−0.092 eV) after adsorption and has a moderate adsorption energy, which could be candidate material for explosive vapor sensing. This theoretical work is proposed to provide guidance and clue for experimentalists to develop more effective two-dimensional materials for environmental safety and sustainability.

Published: December 2020

From the geomorphological cartography, the geometric and spatial distribution of the quaternary forms and deposits are analyzed, with special relevance to the fluvial terraces that allow obtaining the chronology of the successive landscape changes of the course of the Tagus River attributed to the activity of the Fault of Alentejo-Plasencia (APF). The “Appalachian” relief of Monfragüe National Park, constituting a series of quartzitic combs with direction NW, between which they find slopes, hills and valleys following the same direction, for the dismantlement of the Cenozoic cover that was covering the substratum (still present in the central sector) and encasement of the Rivers Tagus and Tiétar. The remains of fluvial terraces inside and outside the Park stand out at different heights and so they originate from different times and show different landscapes along the routes of the Tagus river and its movement over time. In the north end (basin of the Campo Arañuelo), there are remains of ten fluvial terraces of relative importance attributed to the River Tagus (with heights relative to the thalweg between 120 and 20 m). In the south edge, there are eight levels attributed to a former fluvial drainage network, which assimilates to the River Tagus, with the more recent level reaching over 280 m on the current river. Neotectonics readjustments that rejuvenated the relief produced the elevation of the socle and cover, at the time of diversions in the path of the fluvial network, up to the structure and encasement (for supertax and/or antecedence). During the Quaternary, the activity of the Alentejo-Plasencia Fault (APF) has given rise to palaeogeographic changes in the fluvial valley of the Tagus River. During the ancient Lower Pleistocene, its course passed south of the current one (Talaván-Torrejón el Rubio basin); at the end of the Lower Pleistocene, it came out crossing the syncline through the Boquerón porthole, and the meander that bordered the town of Almaraz was abandoned; at the beginning of the Middle Pleistocene, it changes its direction, from NE–SW to SE–NW, leaving the porthole and joining the Tiétar river within the Park; later it moves somewhat to the south. These changes in the route and the anomalous fitting of the course of the Tagus River into the Paleozoic substrate, have been attributed to the APF, which, through impulses, has had a great activity from the Lower Pleistocene to the Middle Pleistocene.

Disability is an imbalance of interactions between biological conditions and the surrounding social environment. Disability is never separated from understanding normality. However, normality that results in normal can harm the personal lives of people with disabilities. Likewise with theology and Christianity tends to ignore the reality of persons with disabilities with biased interpretations of the Bible. John 9: 1-40 gives another dimension, Jesus healed and even defended people with disabilities. This text gives hope for the good treatment of Jesus for persons with disabilities. However, the reality in this life is not like that. For this reason, this study deals with the text of John 9: 1-40 using a critique of the reader's response to finding out, first, the response of persons with disabilities to the text, and secondly the meaning of God's work through persons with disabilities. This research focuses on diverse groups of people with disabilities at the Yayasan Cergas, Maluku. AbstrakDisabilitas merupakan ketidakseimbangan interaksi antara kondisi biologis dan lingkungan sosial sekitar. Disabilitas memang tidak pernah terlepas dari pemahaman normalitas. Akan tetapi, normalitas yang menghasilkan norma-lisme dapat memberikan dampak negatif bagi kehidupan pribadi penyandang disabilitas. Begitu juga dengan teologi dan kekristenan yang cenderung mengabaikan realitas penyandang disabilitas dengan berbagai penafsiran Alkitab yang bias. Yohanes 9:2-3 memberikan dimensi lain, Yesus menyem-buhkan, bahkan membela kaum disabilitas. Teks ini memberikan pengha-rapan akan perlakuan yang baik dari Yesus bagi penyandang disabilitas. Namun, kenyataan dalam kehidupan sekarang tidak seperti demikian. Untuk itu, studi ini menggumuli teks Yohanes 9:2-3 menggunakan suatu kritik tanggapan pembaca untuk mengetahui, pertama, respon penyandang disabi-litas terhadap teks tersebut, dan kedua, pemaknaan karya Allah melalui diri penyandang disabilitas. Penelitian ini berfokus pada kelompok penyandang disabilitas yang beragam pada Yayasan Cergas, Maluku.

Narav došašća prema Zbornoj molitvi Prve nedjelje došašća
Authors: Volarević Domagoj
Published: December 2020

Zborna molitva jedna je od
predsjedateljskih molitava (pokraj darovne i popričesne) koje su u
euharistijskom slavlju pridržane svećeniku. Njome se, kako to zgodno izriče
Opća uredba Rimskoga misala, izriče
narav slavlja. Došašće ili advent, vrijeme je u liturgijskoj godini koje
kronološki neposredno prethodi Božiću, ali se također nastavlja nakon tzv.
posljednjih nedjelja kroz godinu. Takav vremenski položaj daje mu mogućnost
simbolizma i simboličkih elemenata kojima govori i poučava i o Božiću, dakle
Kristovu rođenju ili prvom dolasku u tijelu, ali i o drugom Kristovu dolasku u
slavi. Konačno nedjelja kao osnovni kršćanski blagdan, određuje ritam cijeloj
crkvenoj, liturgijskoj godini. Naravno, i u došašću. Nedjelje su stoga osnove
razvoja poruke i teologije svakoga liturgijskoga ciklusa. Tako zborne molitve u
nedjelje došašće izriču na sažet i jezgrovit način ono što se slavi. Prva
nedjelja došašća i njezina zborna molitva u euharistijskom slavlju svojevrsni
je uvod u došašće i upućuje na daljnji razvoj i tumačenje značenja i naravi ne
samo te nedjelje, već, možemo reći, i cijeloga došašća. Kroz prizmu značenja
osnovnih pojmova u zbornoj molitvi Prve nedjelje došašća te njihovo tumačenje u
kontekstu slavlja, osvjetlat ćemo neke manje naglašene vidove došašća.
