Published: January 2021

Abstract
Nitrous oxide (N2O) gas transfer was studied in a full-scale process to correlate liquid phase N2O concentrations with gas phase N2O emissions and compare methods of determining the volumetric mass transfer coefficient, KLa. Off-gas and liquid phase monitoring were conducted at the Viikinmäki wastewater treatment plant (WWTP) over a two-week period using a novel method for simultaneous measurement of dissolved and off-gas N2O and O2 from the same location. KLa was calculated with three methods: empirically, based on aeration superficial velocity, from experimentally determined O2 KLa, and using a static value of best fit. The findings of this study indicated trends in local emitted N2O consistently matched trends in local dissolved N2O, but the magnitude of N2O emissions could not be accurately estimated without correction. After applying a static correction factor, the O2 method, using experimentally determined O2 KLa, provided the best N2O emission estimation over the data collection period. N2O emissions estimated using the O2 method had a root mean square error (RMSE) of 70.5 compared against measured concentrations ranging from 3 to 1,913 ppm and a maximum 28% error. The KLa value, and therefore the method of KLa determination, had a significant impact on estimated emissions.

Published: January 2021

Artykuł dotyczy koncepcji zrównoważonego rozwoju (sustainable development) osadzonej w kontekście zmian kulturowych i cywilizacyjnych. Można ją traktować jako alternatywę i nową panoramę, otwierającą perspektywiczne widoki na dalszy trwały i zrównoważony rozwój cywilizacyjny. Idea ta, jest globalną strategią rozwoju. Polega na włączeniu środowiska naturalnego do rozwoju społeczno-gospodarczego regionu, kraju czy w ujęciu globalnym całego świata. Zakłada trwałą poprawę jakości życia współczesnych i przyszłych pokoleń, co integralnie łączy się z poprawą stanu środowiska człowieka. Wskazuje też na potrzebę rozwoju duchowego człowieka i zamianę celów rozwojowych z materialnych na niematerialne. W tych ogólnych założeniach i celach, zrównoważony rozwój napotyka na wiele praktycznych i mentalnych problemów, które hamują, bądź wręcz uniemożliwiają efektywne wprowadzanie tej koncepcji w życie.

:
diseases initiated by Coronavirus (CoV) have become the major public health
problems worldwide in the last two decades. The recent emergence of the deadly COVID-19 due to
SARS-CoV-2 has created unprecedented pandemic situations around the globe making the need for
antiviral molecules to treat it. Encountering the health conditions of the patients with synthetic
molecules has shown some unpredictable results, including side effects. To face this complex situation,
natural products can be good sources of enormous treatment options with fewer side effects.
Wide diversity, easy availability, and a good number of scientific researches on Asian origin natural
products can be a great tool to meet this critical situation. This paper reviews the currently available
Asian natural products with potential antiviral effects on CoV. It includes the potential natural
products of whole plant extract, partial plant extract, isolated pure compounds, and isolated pure
set of compounds. Besides, the available information of in vitro and in silico from very recent papers
are also summarized for the ease of future research. As a rapid search for a potential anti-CoV
therapy is undergoing, Asian natural products will provide promising results but still, there are
many challenges in front of us, including the robust in vitro assay to confirm the antiviral property,
toxicity analysis, and fulfillment of regulatory needs. The use of appropriate natural products with
the potential for a safe and more effective anti-CoV property requires multidisciplinary research
with preclinical and clinical researchers, which will improve their clinical applications.
Examining the Relationship Between the Use of a Mobile Peer-Support App and Self-Injury Outcomes: Longitudinal Mixed Methods Study
Authors: Kruzan Kaylee Payne , Whitlock Janis , Bazarova Natalya N 
Published: January 2021

Background
Many individuals who self-injure seek support and information through online communities and mobile peer-support apps. Although researchers have identified risks and benefits of participation, empirical work linking participation in these web-based spaces to self-injury behaviors and thoughts is limited.

Objective
This study aims to investigate the relationship between behavioral and linguistic traces on a mobile peer support app and self-injury outcomes.

Methods
Natural use data and web-based surveys (N=697) assessing self-injury outcomes were collected from 268 users (aged 13-38 years; median 19; 149/268, 55.6% female) of a mobile peer-support app for 4 months. Participants were identified as having posted self-injury content using an internal classifier. Natural log data was used to predict self-injury outcomes in a series of multilevel logistic and linear regressions.

Results
Greater engagement on a mobile peer-support app was associated with a decreased likelihood of self-injury thoughts (odds ratio [OR] 0.25, 95% CI 0.09-0.73) and fewer intentions to self-injure (b=−0.37, SE 0.09), whereas posting triggering content was associated with an increased likelihood of engaging in behaviors (OR 5.37, 95% CI 1.25-23.05) and having self-injury thoughts (OR 17.87, 95% CI 1.64-194.15). Moreover, viewing triggering content was related to both a greater ability to resist (b=1.39, SE 0.66) and a greater intention to self-injure (b=1.50, SE 0.06).

Conclusions
To our knowledge, this is the first study to connect naturally occurring log data to survey data assessing self-injury outcomes over time. This work provides empirical support for the relationship between participation in online forums and self-injury outcomes, and it articulates mechanisms contributing to this relationship.

Published: January 2021

Gonadotropine Releasing Hormone (GnRH) is one of the recommended hormones to overcome ovulation problems and it can increase pregnancy rate so that it is used in government programs to increase cattle population in Indonesia, although the results are not yet optimal. The purpose of this study is to compare the composition of bovine GnRH receptor nucleotides with the GenBank reference so that the level of genetic diversity of bovine receptors in Indonesia is known. PCR product sequencing using Promoter F and Exon 1 R primers were further aligned with the reference sequences of Bos Taurus GnRHR mRNA GenBank using the MEGA X program. The results of the analysis found the presence of Single Nucleotide Polymorphism (SNP) in the coding region of 1st cow position 38(A> T), 261(C > T), 342(C >T), 411(C >T) and 495(C > T) and 2nd cow positions 261(C >T). Changes in amino acids were also detected in 1st cow position 13 (H> L). The presence of SNP was found to indicate genomic variation between individuals at cattle receptors in Indonesia.

Пусть $M_{n}=\sup_{P\in \mathcal{P}_{n}\setminus \{0\}} \frac{\max_{x\in[-1,1]}|P(x)|}{\int_{-1}^{1}|P(x)|\,dx}$ --- константа Никольского междуравномерной и интегральной нормами для алгебраических полиномов с комплекснымикоэффициентами степени не выше $n$. D. Amir и Z. Ziegler (1976) доказали, что$0.125(n+1)^{2}\le M_{n}\le 0.5(n+1)^{2}$ для $n\ge 0$. Аналогичная оценкасверху получена T.K. Ho (1976). F. Dai, D. Gorbachev и S. Tikhonov (2019--2020)уточнили этот результат, установив, что $M_{n}=Mn^{2}+o(n^{2})$ при $n\to\infty$, где $M\in (0.141,0.192)$ --- точная константа Никольского для целыхфункций экспоненциального сферического типа в пространстве$L^{1}(\mathbb{R}^{2})$ и функций экспоненциального типа в $L^{1}(\mathbb{R})$с весом $|x|$. Мы доказываем, что для произвольного $n\ge 0$ имеем $M(n+1)^{2}\le M_{n}\leM(n+2)^{2}$, где $M\in (0.1410,0.1411)$. Данное утверждение также позволяетуточнить точную константу Джексона--Никольского для полиномов на евклидовойсфере $\mathbb{S}^{2}$. Доказательство базируется на взаимосвязи алгебраическихконстант Никольского с тригонометрическими константами Бернштейна--Никольскогои наших результатах об оценках последних (2018--2019). Также мы применяемхарактеризацию экстремального алгебраического полинома, полученную D. Amir иZ. Ziegler (1976), В.В. Арестовым и М.В. Дейкаловой (2015). С помощью этойхарактеризации мы составляем тригонометрическую систему для определения нулейэкстремального полинома, которую решаем приближенно с необходимой точностью спомощью метода Ньютона.
The Role of Video-Assisted E-Learning in Intrauterine Contraceptive Device Insertion Training
Authors: Peng Ng Lai , Ling Eileen Koh Yi 
Published: January 2021

Introduction: Intrauterine contraceptive device (IUCD) insertion is an important procedural skill for primary care physicians. Procedural skill training can be challenging. E-learning has been rapidly employed in medical education. The purpose of this study was to evaluate the role of a video-assisted e-learning module in knowledge and skill transfer for IUCD insertion training.
Methods: We used a quasi-experimental, one-group, pre/posttest study design. Thirty-one primary care doctors (family medicine residents and new medial officers) at a primary care training center participated in the study. All participants assessed the e-learning module at the training center. We performed on-site pre/posttests of knowledge and procedural steps (posttest only). We obtained satisfaction with e-learning and perceived confidence level with an anonymous questionnaire survey.
Results: There was a significant increase in the knowledge test scores from a median interquartile range score of 12 (10-15) to 18 (17-19) post-e-learning (P&lt;.01). All participants attained the minimum passing score of 15 of 20 (75%) post-e-learning. However, only 20 of 31 (64.5%) participants met the minimum passing standard for procedural step test post-e-learning. Ninety-three percent of the participants reported satisfaction with the e-learning course. The median score for confidence level in performing the procedure increased significantly after e-learning.
Conclusion: The e-learning module may be an effective way of delivering instructional content in procedural training. It provides time and location flexibility and is useful for pretraining. Psychomotor skills for clinical procedures, however, may be difficult to acquire by e-learning alone. It must be supplemented with deliberate practice and hands-on learning in simulation workshops.
Nuovi processi biologici a membrane per la depurazione sostenibile delle acque reflue
Authors: Cairone Stefano 
Published: January 2021

I bioreattori a membrana (MBR) combinano il processo di degradazione
biologica a fanghi attivi e il processo fisico di filtrazione con
membrane, costituendo un sistema di trattamento avanzato delle acque
reflue. Tra i numerosi vantaggi di questa tecnologia, assume
particolare importanza l’elevata efficienza depurativa: gli MBR
garantiscono la rimozione sia di contaminanti convenzionali che di
contaminanti emergenti. Tuttavia, gli MBR presentano degli svantaggi
legati principalmente agli elevati costi di investimento e di gestione
degli impianti e al controllo del fouling. L’introduzione dei
bioreattori a membrana dinamica auto-formante (SFDMBR), basati
sull’utilizzo di un materiale di supporto a pori grossolani a basso
costo per la formazione di una membrana dinamica auto-formante, consente
di ottenere elevate prestazioni depurative a fronte di ridotti costi di
investimento. Gli elettro-bioreattori a membrana (e-MBR) combinano
processi elettrochimici nei sistemi MBR, con conseguente incremento
dell’efficienza depurativa e riduzione del fouling. Combinando la
tecnologia SFDMBR con quella e-MBR si ottiene un sistema ibrido
estremamente innovativo: l’elettro-bioreattore a membrana dinamica
auto-formante (e-SFDMBR).

It has been widely recognized that interlanguage fossilization is the common phenomena in second language acquisition. The present study tried to investigate the students’ writing performance to find out whether interlanguage fossilization occured or not. The primary goal of this research was to give information relating to interlanguage fossilization in students’ writing performance.This research was qualitative research. The writer used observation, documentation and interview to collect the data. Purposive sampling was the technique for choosing the ten students of the sixth and the eight semester of English Education Study Program of IAIN Jurai Siwo Metro in the Academic Year of 2017/2018. The result of this research showed that there were two types of interlanguage fossilization commonly produced by students. They were syntactical fossilization and morphological fossilization. Syntactical fossilization consisted of 71, 86% and morphological fossilization consisted of 28, 14%. Moreover, interlanguage fossilization phenomenon in students’ writing performance was caused by the students’ low English proficiency. Therefore, the students should be more active to improve their English ability.

People have desires to search for the truth and to have broad knowledge. The internet, which was once considered as one of the media to find accurate sources of information, now has become a source of less accurate news. So there needs to be a filter in consuming news from the internet. The purpose of this study is to look at the spread of hoax news because of the lack of awareness. The majority of social media users in the current era do not have an ethical foundation in using their right to express their opinions properly which result in hoaxes. We use literature review method to collect all the information required. In the end, we conclude that people must give an opinion by thinking about the truth first of what they have conveyed. From the truth, it can be understood that something must be justified. In accordance with the truth meant by Al-kindi that in seeking truth must to find the main source of the source itself.

Jati (Tectona grandis Linn.f) dikembangkan secara intensif di Indonesia terutama di Pulau Jawa dengan luas pengelolaan hutan tanaman ± 1 juta Ha. Di Asia Tenggara jenis ini ditanam pula oleh negara Philipina, Thailand, Malaysia, Laos, Vietnam bagian Selatan dan Myanmar dengan luas bervariasi. Namun demikian pengetahauan mengenai variasi morfologi dan pemanfaatan untuk kegiatan bioteknologi dan pemuliaan masih berkisar pada satu spesies saja yaitu Tectona grandis. Sedangkan spesies lain seperti Tectona abludens, Tectona hamiltoniana dan Tectona philiphinensis belum banyak diketahui.Penelitian dilakukan dengan mengambil sampel daun di 3 pengembangan jati di Pulau Jawa yaitu Cepu dan Randublatung Jawa Tengah, Nglambangan Bojonegoro Jawa Timur dan Ciamis Jawa Barat. Untuk Spesies Tectona abludens sampel daun diambil di daerah Dlingo, Bantul DIY dan Selang, Gunungkidul. Sedangkan untuk jenis Tectona philiphinensis lebih dalam dipelajari berdasarkan informasi yang diperoleh dari Kementrian Kehutanan Philipina dan untuk jenis Tectona hamiltoniana dilengkapi dengan data dan informasi dari Kementrian Kehutanan Myanmar. Sampel daun dari tiap jenis diambil 2 daun (daun muda dan daun tua) masing-masing 5 ulangan. Pengamatan terhadap bentuk duduk daun, jumlah tulang daun primer dan sekunder serta pola tulang daun didiskripsikan dan dibandingkan antara keempat spesies tersebut. Morfologi bunga, kulit batang, kayu, biji dan bentuk percabangan digunakan juga untuk melengkapi variasi morfologi masing-masing spesies. Variasi morfologi yang ada dipergunakan untuk mengetahui variasi empat spesies Tectona sp tersebut sehingga diketahui karakter-karakter tiap jenis yang berpeluang untuk dimanfaatkan dalam kegiatan pemuliaan pohon baik melalui pemuliaan konvensional atau bioteknologi.Tectona grandis memiliki morfologi yang lebih dekat dengan Tectona abludens, sedangkan Tectona hamiltoniana dan Tectona phillipinensis memiliki morfologi khas yang berbeda dengan lainnya. Beberapa karakter morfologi diantara keempat spesies tersebut berpeluang diamanfaatkan untuk kegiatan pemuliaan jati antara lain kelurusan batang, kemampuan adaptasi di lahan kering dan ketahanan terhadap penyakit.
EUROPEAN GREEN DEAL AND THE NEW POLICY GOALS IN TRANSPORT AND MOBILITY - HOW GAMIFICATION CAN INFLUENCE PRO-ENVIRONMENTAL BEHAVIOUR FOR CUTTING CARBON EMISSIONS IN THE EU
Authors:   SNSPA, BUTNARU-TRONCOTĂ Miruna 
Published: January 2021

Road traffic is one of the major sources of many of the worst pollutants, including carbon dioxide (CO2), carbon monoxide, carcinogenic particles and noise. The past decades have seen a dramatic rise in these harmful effects on human health, that proved to cause at the same time massive damage to the natural and built environment. In response to this aggravating situation, the new European Commission’s President Ursula von der Leyen placed as the centrepiece of her political mandate ‘the European Green Deal’, a comprehensive climate and nature package of measures to make Europe climate neutral by 2050. To reach this very ambitious goal, there is a need for very creative and efficient policy solutions. And this is the scope of the current study.	As the sustainability concerns become vital for policy planning, the paper advocates for the need of all EU’s main stakeholders to realise the potential of ‘green gamification’ to help EU member states reach these ambitious policy goals, particularly in the field of transport and mobility - which are of crucial importance for overall CO2 reduction. Placed at the intersection of technology innovation and the need to find more efficient ways to protect the environment, ‘green gamification’ is an emerging concept that refers to the usage of game mechanics when it comes to engaging people, with the purpose to change their behaviour on sustainability issues. In short, it aims to motivate a sustainable behaviour within companies, institutions and citizens, with the use of interactive games, in order to fight against pollution and climate change. Applied to the field of transport and mobility, green gamification implies using strategies to cut carbon emissions especially by convincing people to reduce the use of private cars. But how can we better incentivise citizens’ behaviour for cutting carbon emissions and achieve the new EU transport and mobility policy goals for 2050? To tackle this relevant question the article aims to assess the potential of ‘green gamification’ to help EU member states reach these ambitious policy goals.
