Demonstration of the impacts of anti-sedimentation techniques on Japanese reservoir siltation via mass data ANN analysis
Authors: Landwehr Tobias , Kantoush Sameh Ahmed , Nohara Daisuke , Sumi Tetsuya , Pahl-Wostl Claudia 
Published: February 2022

Abstract
Reservoirs have been installed as long-term assets to guarantee water and energy security for decades, if not centuries. However, the effect of siltation undermines reservoirs' sustainability because it significantly reduces the reservoirs' original capacity. Extreme events such as typhoons, floods and droughts are posited to have extreme impacts on sediment inflow and deposition in reservoirs. The same holds true for ISMTs (implemented sediment management technologies), such as dredging, spilling and bypassing. However, the large-scale analysis of their effects on reservoir sedimentation progression, recovery and development was not feasible due to data scarcity and technological restrictions. The present paper closes this information gap by conducting a GRU (gated recurrent unit) neural network analysis of 1,224 Japanese reservoirs, for which the sedimentation, local precipitation, extreme events and ISMTs were monitored between 2000 and 2017. The network reveals the beneficial impacts of dredging, spilling and bypassing. The results also demonstrate the potential of smart management and improved monitoring for sedimentation threat abatement. Thus, foresighted engineering and dedicated governance action in flood and drought scenarios can significantly strengthen the sustainable behavior of key infrastructure elements such as reservoirs.
The effect of triangular prismatic elements on the hydraulic performance of stepped spillways in the skimming flow regime: an experimental study and numerical modeling
Authors: Roushangar Kiyoumars , Akhgar Samira , Shahnazi Saman 
Published: February 2022

AbstractThe stepped spillway is a cost-effective hydraulic structure to dissipate the energy of large water flow over the spillway of a dam. In this study, the focus was placed on the effects of triangular prismatic elements (TPEs) on the hydraulic performance of a stepped spillway. Nine stepped spillway models were experimentally and numerically investigated with different shapes and layouts of TPEs. To adopt a proper turbulent model, RNG k-ε and standard k-ε models were utilized. The computational model results satisfactorily simulated the complex flow over the stepped spillway of experiment cases, including velocity distributions and pressure profiles on the step surfaces. The results indicated that the installation of TPEs on stepped spillways can be an effective way to reduce cavitation effects. Installing TPEs on stepped spillways increased the energy dissipation rate up to 54%. The performance of stepped spillways was improved when TPEs were spaced more closely together. Furthermore, the relationships between the roughness coefficient (f) and the ratio of the critical depth to the step roughness (yc/k) were obtained with high accuracy using the experimental data.

Published: February 2022

Abstract
This study involved novel-designed sludge biochar (SB) adsorbed for arsenic removal with lower operating costs and higher adsorption efficiency properties. Generally, biochar only relies on micropores for pollutant adsorption, but physical adsorption is not highly efficient for arsenic removal. Therefore, in order to improve the removal efficiency of arsenic by SB, diethylenetriamine (DETA) and FeCl3 were used in this study to modify the surface of SB by an immersion method. The objectives of this research are to obtain optimum operation conditions by assessing the effect of different Fe content, pH and initial concentration on adsorbing arsenic. This study is the first to use Density Functional Theory (DFT) to simulate and verify the adsorption mechanism of arsenic by SB. Results showed the presence of amine/iron oxyhydroxides functional groups greatly promoted SB surface activity and its arsenic adsorption potential. The surface area, pore volume and pore size of the SB were estimated to be 525 m2 g−1, 0.35 cm3 g−1 and 8.71 nm, respectively. The DFT model result is the same as the result of arsenic adsorption performance with high adsorption energy (−246.3 kJmol−1) and shorter bond distances (1.42 Å), indicating strong chemical adsorption between arsenic and material. The reaction mechanism is divided into four pathways, including oxidation-reduction, complexation, electrostatic adsorption and pore adsorption.

Published: February 2022

Abstract
Although in a critical position in the economy, the paper industry releases a lot of wastewater that requires adequate treatment for sustainable development. This study presents an application of Life cycle assessment (LCA) with the ReCiPe tool on the wastewater treatment plant (WWTP) of a paper factory in Vietnam to evaluate the environmental effect of the individual techniques in WWTP, especially the internal circulation (IC) reactor, a pioneer and practical anaerobic technology. Both Midpoint and Endpoint categories results demonstrated that chemical use and electricity consumption mainly contributed to the environmental impact in the WWTP. The Dissolved air flotation (DAF) and Moving bed biofilm reactor (MBBR) are classified as effective techniques to reduce the impacts on the environment. Moreover, the comparison of LCA between IC and up-flow anaerobic sludge bed (UASB) shows that IC is the better practically green technique for the environment.
Evaluation of Mechanical Properties and Antibacterial Activity of Nano Titania-Enriched Alkasite Restorative Material: An In Vitro Study
Authors: Aref Neven S. , Abdallah Reham M. 
Published: February 2022

Background:
A biocompatible additive with the ability to establish antibacterial action for restorative materials without sacrificing their physical properties is always in demand. Nano titania (TiO2 nanoparticles) was shown to have antimicrobial action against a wide range of microorganisms. Alkasite is a modern esthetic restorative material that has outstanding properties; however, it is deficient in antibacterial activity.

Objective:
TiO2 nanoparticles (NPs) were included in alkasite, and both mechanical properties and antibacterial activity of the new formulations were assessed.

Materials and Methods:
Nano titania powder was coupled to alkasite powder in proportions of 3 and 5% (w/w). There were 105 specimens made in total. Evaluation parameters were compressive strength, surface microhardness, surface roughness, water sorption and solubility, and antibacterial activity. One and two-way ANOVA were used for the statistical analysis, followed by Tukey′s test (p<0.05).

Results:
Both ratios of nano titania, 3 and 5% (w/w), significantly increased compressive strength, antibacterial activity against different pathogens, and decreased water solubility of alkasite (p<0.05). Only 5% (w/w) nano titania-modified alkasite exhibited significant decrease in water sorption (p<0.05). Conversely, an insignificant increase in microhardness and surface roughness was observed with both ratios, 3 and 5% (w/w) of nano titania (p˃0.05).

Conclusion:
Nano titania seems to be a very promising complementary additive to the alkasite restorative material, capable of generating considerable antibacterial effectiveness while also enhancing certain mechanical properties.

Authors: Kato Chihiro , Wang Dong , Nakamura Noriko , Sasajima Takayoshi , Yoshisue Hajime 
Published: February 2022

Objective:
To evaluate the long-term safety and efficacy of glycopyrronium (GLY) in patients with COPD in a real-world setting in Japan.

Methods:
This 52-week, multicentre, post-marketing surveillance conducted in Japan, between February 2013 and August 2019, included patients using GLY for the first time for the relief of airway obstructive disorder-related symptoms. Safety outcomes included incidence of adverse events (AEs), serious AEs (SAEs), adverse drug reactions (ADRs), serious ADRs (SADRs) and priority variables included cardiovascular/cerebrovascular (CCV) AEs and anticholinergic AEs during the 52-week period. Safety outcomes were also assessed in elderly patients. Efficacy outcomes included physician’s global assessment, COPD assessment test (CAT) and lung function test.

Results and Discussion:
Of the 1,331 patients registered for this surveillance, safety and efficacy outcomes were evaluated in 1,277 patients. In the safety analysis population, the incidence of AEs was 15.51%, SAEs 4.70%, ADRs 5.01% and SADRs 0.31%. The CCV AEs and anticholinergic AEs were reported by 0.70% and 2.58% patients, respectively. Physician’s global assessment showed that the overall response rate at the last assessment was 70%. The mean (95% CI) CAT scores decreased from the start of treatment to Week 52 with GLY, (−6.2 [−7.0 to −5.4]). Lung function in terms of trough FEV1 and FVC improved over time from the start of GLY to Week 52.

Conclusion:
GLY demonstrated an acceptable long-term safety profile with no new safety concerns in a real-life setting. It demonstrated improvement in lung function and symptom control in Japanese COPD patients.

Authors: Raika Alise E. , Sidhoma Elga , Hasnere Sigita 
Published: February 2022

Background:
Cutaneous metastases are cancerous cells in the dermis and hypodermis and can develop from every type of malignancy. The involvement of the skin in the metastatic process is considered to be quite rare and carries a poor prognosis, but it is of great importance in the management, treatment and self-esteem of the patient.

Objective:
The objective of this paper is to collect research data on clinical signs of cutaneous metastases and the use of dermoscopy in their diagnostic process.

Results:
Cutaneous metastases present with different clinical variants and dermoscopic findings, the most common being non-painful skin-colored nodules with various vascular structures seen in dermoscopy. There are not many reports on the dermoscopic findings of cutaneous metastases.

Conclusion:
Cutaneous metastases remain a rare diagnosis but are of great clinical importance. As the use of dermoscopy rises yearly, a better understanding of the dermoscopic features in cutaneous metastases should be obtained and reported.
Therapist-Assisted Web-Based Intervention for Prolonged Grief Disorder After Cancer Bereavement: Randomized Controlled Trial
Authors: Kaiser Julia , Nagl Michaela , Hoffmann Rahel , Linde Katja , Kersting Anette 
Published: February 2022

Background
Bereavement due to cancer increases the risk of prolonged grief disorder. However, specialized treatment options for prolonged grief after a loss due to illness are still scarce.

Objective
The aim of this study is to extend previous findings by evaluating a web-based cognitive behavioral intervention with asynchronous therapist support, consisting of structured writing tasks adapted specifically for prolonged grief after cancer bereavement.

Methods
The intervention was evaluated in a purely web-based randomized waitlist-controlled trial. Open-access recruitment of participants was conducted on the web. Prolonged grief (Inventory of Complicated Grief), depression, anxiety, posttraumatic stress, posttraumatic growth, somatization, sleep quality, and mental and physical health were assessed on the web via validated self-report measures.

Results
A total of 87 participants were randomized into the intervention group (IG; 44/87, 51%) or the waitlist control group (43/87, 49%). Of the participants, 7% (6/87) dropped out of the study (5/44, 11%, in the IG). Of the 39 completers in the IG, 37 (95%) completed all intervention tasks. The intervention reduced symptoms of prolonged grief (intention-to-treat: P<.001; η2=0.34; Cohen d=0.80) to a clinically significant extent. It had favorable effects on depression, anxiety, posttraumatic stress, posttraumatic growth, and overall mental health but not on somatization, sleep quality, or physical health.

Conclusions
The web-based intervention for prolonged grief after cancer bereavement is effective in reducing symptoms of prolonged grief disorder and accompanying syndromes in a timely, easily realizable manner and addresses specific challenges of bereavement to illness. Considering web-based approaches in future mental health care policy and practice can reduce health care gaps for those who are bereaved to cancer.

Common Dermatologic Disorders in Down Syndrome: Systematic Review
Authors: Lam Megan , Lu Justin Di , Elhadad Levi , Sibbald Cathryn , Alhusayen Raed 
Published: February 2022

Background
Down syndrome (DS) has been associated with cardiovascular, gastrointestinal, and immune-related abnormalities. Several dermatologic conditions, including hidradenitis suppurativa, have also been found to be associated with DS.

Objective
The objective of this study was to characterize the prevalence, presentation, and unique features of dermatologic disorders associated with DS.

Methods
Electronic searches of EMBASE (via Ovid), MEDLINE (via Ovid), and Web of Science databases were conducted on December 14, 2020. Observational studies including case reports of patients with DS presenting with concomitant primary dermatologic disorder were included.

Results
This systematic review captured 40 observational studies and 99 case reports, including 10 observational studies that examined the prevalence of common skin disorders in patients with DS. The most common dermatologic conditions reported includes atopic dermatitis (8 studies, n=180; 19.7% mean prevalence), hidradenitis suppurativa (15, n=478; 3.2%), ichthyosis (4, n=16; 4.7%), lichen nitidus (6, n=6; 1.1%), psoriasis (21, n=65; 4.8%), alopecia areata (27, n=253; 7.4%), vitiligo (8, n=40; 4.4%), onychomycosis (3, n=198; 24.7%), calcinosis cutis (14, n=15), connective tissue nevi (6, n=6), dermatofibroma (3, n=3), melanoma (3, n=3), syringomas (14, n=182; 21.2%), and elastosis perforans serpiginosa (19, n=24; 0.5%).

Conclusions
Our results indicate an increased prevalence of common cutaneous disorders in patients with DS, particularly infectious, inflammatory, autoimmune, and connective tissue conditions. Current guidelines for the screening, general management, and use of systemic immunomodulatory agents in this patient population are lacking. Patients with DS would benefit from screening for dermatologic disorders not otherwise regularly performed for earlier diagnosis and treatment.

Pedagogy of uncertainty
Authors: Videla-Reyes Ronnie , Aguayo Claudio 
Published: February 2022

Educators around the world are facing the challenges and opportunities of 21st Century education, such as the COVID-19 pandemic, STEAM education, and the rise of digital immersive technologies presenting a promising field for the development of new ways to maximize the learning experience (Bakker, Cai & Zenger, 2021) The integration of science, technology, engineering, art and mathematics (STEAM) offers an approach to educational design based on curricular integration and learning by doing with analog and virtual technologies (Quigley et al., 2020). In turn, STEAM promotes important pedagogical changes that encourage the development of new skills focused on collaborative work, inquiry and creativity in the face of a challenge or problem to be solved, as well as optimal sensorimotor deployment through haptic and visual perception when using emerging digital immersion technologies such as virtual and augmented reality (Videla-Reyes, Aguayo & Veloz, 2021). All these changes lead to a new framework of pedagogical action based on uncertainty, since they are unfamiliar or unknown in the field of traditional education.

Based on the above, we propose here the idea of a ​​’pedagogy of uncertainty’, which can be read in light of the latest and unpredictable changes that 21st Century education is experiencing due to the COVID-19 pandemic, the emergence of technological tools and unfamiliar virtual and online platforms that teachers and students had to learn and use during the march of the virus. The approach that we suggest here is based on the potential of STEAM educational environment design that focuses on providing signs or patterns of an emerging world, unlike traditional teaching methods in which the path to which students should arrive is already laid down in advance. From a STEAM educational design approach, the teacher and her/his students lay down a path in walking together, a motto used by the enactive approach to cognition that considers "cognition as embodied action that is always oriented towards something absent: on the one hand, there is always a next step for the system in its perceptually guided action; for the rest, the acts of the system are always directed towards situations that are not yet in act” (Varela, Thompson & Rosch, 1991, p.238). In this presentation, we explore the notion of pedagogy of uncertainty in the light of enactivism, based on theoretical and empirical evidence about how teachers and students deal with an uncertain world by actively participating in integrated educational environments based on learning by doing approaches (Abrahamson, Dutton & Bakker, 2021). In particular, we make special reference to how teachers can make their students learn from clues, impoverished traces, or traces of information available within their learning environments to solve a challenge or problem, to the extent that they investigate, create, manufacture and/or actively participate in technology inside and beyond the classroom.
