DecTree v1.0 – chemistry speedup in reactive transport simulations: purely data-driven and physics-based surrogates
Authors: De Lucia Marco , Kühn Michael
Published: July 2021

Abstract. The computational costs associated with coupled reactive transport
simulations are mostly due to the chemical subsystem: replacing it
with a pre-trained statistical surrogate is a promising strategy to
achieve decisive speedups at the price of small accuracy losses and
thus to extend the scale of problems which can be handled. We
introduce a hierarchical coupling scheme in which “full-physics”
equation-based geochemical simulations are partially replaced by
surrogates. Errors in mass balance resulting from multivariate
surrogate predictions effectively assess the accuracy of
multivariate regressions at runtime: inaccurate surrogate
predictions are rejected and the more expensive equation-based
simulations are run instead. Gradient boosting regressors such as
XGBoost, not requiring data standardization and being able to handle
Tweedie distributions, proved to be a suitable emulator. Finally, we
devise a surrogate approach based on geochemical knowledge, which
overcomes the issue of robustness when encountering previously
unseen data and which can serve as a basis for further development of
hybrid physics–AI modelling.
Laboratory experiments on the influence of stratification and a bottom sill on seiche damping
Authors: Medjdoub Karim , Jánosi Imre M. , Vincze Miklós
Published: July 2021

Abstract. The damping of water surface standing waves (seiche modes) and the associated excitation of baroclinic internal waves are studied experimentally in a quasi-two-layer laboratory setting with a topographic obstacle at the bottom representing a seabed sill. We find that topography-induced baroclinic wave drag contributes markedly to seiche damping in such systems. Two major pathways of barotropic–baroclinic energy conversions were observed: the stronger one – involving short-wavelength internal modes of large amplitudes – may occur when the node of the surface seiche is situated above the close vicinity of the sill. The weaker, less significant other pathway is the excitation of long waves or internal seiches along the pycnocline that may resonate with the low-frequency components of the decaying surface forcing.
Two-dimensional impurity imaging in deep Antarctic ice cores: snapshots of three climatic periods and implications for high-resolution signal interpretation
Authors: Bohleber Pascal , Roman Marco , Šala Martin , Delmonte Barbara , Stenni Barbara , Barbante Carlo
Published: July 2021

Abstract. Due to its micrometer-scale resolution and inherently micro-destructive nature, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is particularly suited to exploring the thin and closely spaced layers in the oldest sections of polar ice cores. Recent adaptions to the LA-ICP-MS instrumentation mean we have faster washout times allowing state-of-the-art 2-D imaging of an ice core. This new method has great potential especially when applied to the localization of impurities on the ice sample, something that is crucial, to avoiding misinterpretation of the ultra-fine-resolution signals. Here we present the first results of the application of LA-ICP-MS elemental imaging to the analysis of selected glacial and interglacial samples from the Talos Dome and EPICA Dome C ice cores from central Antarctica. The localization of impurities from both marine and terrestrial sources is discussed, with special emphasis on observing a connection with the network of grain boundaries and differences between different climatic periods. Scale-dependent image analysis shows that the spatial significance of a single line profile along the main core axis increases systematically as the imprint of the grain boundaries weakens. It is demonstrated how instrumental settings can be adapted to suit the purpose of the analysis, i.e., by either employing LA-ICP-MS to study the interplay between impurities and the ice microstructure or to investigate the extremely thin climate proxy signals in deep polar ice.
Maximal power per device area of a ducted turbine
Authors: Bagheri-Sadeghi Nojan , Helenbrook Brian T. , Visser Kenneth D.
Published: July 2021

Abstract. The aerodynamic design of a ducted wind turbine for maximum total power coefficient was studied numerically using the axisymmetric Reynolds-averaged Navier–Stokes equations and an actuator disc model. The total power coefficient characterizes the rotor power per total device area rather than the rotor area. This is a useful metric to compare the performance of a ducted wind turbine with an open rotor and can be an important design objective in certain applications. The design variables included the duct length, the rotor thrust coefficient, the angle of attack of the duct cross section, the rotor gap, and the axial location of the rotor. The results indicated that there exists an upper limit for the total power coefficient of ducted wind turbines. Using an Eppler E423 airfoil as the duct cross section, an optimal total power coefficient of 0.70 was achieved at a duct length of about 15 % of the rotor diameter. The optimal thrust coefficient was approximately 0.9, independent of the duct length and in agreement with the axial momentum analysis. Similarly independent of duct length, the optimal normal rotor gap was found to be approximately the duct boundary layer thickness at the rotor. The optimal axial position of the rotor was near the rear of the duct but moved upstream with increasing duct length, while the optimal angle of attack of the duct cross section decreased.
Relationship between Microfinance and Sustainable Women Entrepreneurial Performance: The mediating Role of Social capital
Authors: Nawaz Shazia , Muhammad Ramzan  , Shahid Muhammad Sadiq
Published: July 2021

This study aims to investigate the impact of microfinance on poverty reduction through women entrepreneurship in Southern Punjab, Pakistan. We also examine if social capital plays any role in microfinance and women entrepreneurship growth that leads towards poverty reduction. This study uses the data collected through a survey of 210 women entrepreneurs, who secured microfinance loans for their new/established enterprises. By applying correlation and regression analysis techniques, this study finds that access to finance is important for female entrepreneurs and it helps them in realizing their potential as entrepreneurs. A range of entrepreneurial characteristics was found to be critical to the success of women led enterprises in general and to poverty reduction among their families, in particular. Our results reveal that microfinance plays a positive role in women's entrepreneurial performance. We also find that Islamic microfinance contributes more to sustainable women's entrepreneurial performance than non-Islamic microfinance. Although this study used a limited sample of Pakistani female entrepreneurs, yet the results can be relevant to women entrepreneurs in other developing countries with contextual cautions. Future researchers may incorporate more relevant variables and increase the sample size to enhance the understanding of our investigated phenomena.
MODELING AS A CORE COMPONENT OF STRUCTURING DATA
Authors: KONOLD CLIFFORD , FINZER WILLIAM , KREETONG KOSOOM
Published: July 2021

We gave participants diagrams of traffic on two roads with information about eight attributes, including the type of each vehicle, its speed, direction and the width of the road. Their task was to record and organize the data to assist city planners in its analysis. Successfully encoding the information required the creation of a case, a physical record of one repetition of a repeatable observational process. We analyzed data sheets participants created including the methods they used to bind information together into cases. Overall, 79% of their data sheets successfully encoded the data. Even 62% of the middle school students were able to create a bound structure that could hold the critical information from the diagrams. A majority of these structures involved a hierarchy of cases rather than the “flat” case-by-attribute structure that virtually all statistical software require. Our sense is that participants strove to create a structure that modeled the real-world as closely as they could, constructing cases that corresponded to the different sorts of objects they perceived—vehicles with their characteristics nested within road segments with their characteristics.

Authors: KAPITANOFF SUSAN , PANDEY CAROL
Published: July 2021

Seventy-one students in two community college Statistics for the Social Sciences classes took six exams either individually or collaboratively. Assignment to test condition was randomly determined for each exam. Scores on collaboratively-taken exams were significantly higher than those for individually-taken exams, particularly for students with low GPAs and high test anxiety. Women’s, but not men’s, performances on the mid-term and final exams was related to the quality and quantity of their collaborative interactions. Thus, examining both quantity and quality of collaboration adds to our understanding of the underlying mechanisms of collaborative testing.

Young Canadian Muslims: Islamophobia and Higher Education
Authors: Alizai Hassina
Published: July 2021

This study examined Islamophobia in Canadian higher education through the accounts of eight Muslim students in Canadian universities. Qualitative semi-structured interviewing was utilized to investigate how Muslim students report being perceived by faculty, non-Muslim peers, and student service providers. Analysis of interview data yielded six major themes: (1) difficulty in requesting religious accommodations, (2) soft bigotry through low expectations, (3) misrepresentations of Islam in mass media, (4) defensive posturing to combat anti-Muslim sentiment, (5) public emboldening of overt Islamophobia, and (6) resisting and challenging Islamophobic sentiments. The findings of this research indicate that Muslim students experience feelings of marginalization and alienation within higher educational institutions. The respondents articulated the burden of responsibility to take an active role in combatting Islamophobia.
Grading in a Dilemmatic Space : An Exploratory Cross-cultural Analysis of Mathematics and Language Secondary Teachers
Authors: Pasquini Raphaël , Deluca Chris
Published: July 2021

Numerous studies have shown that grading is a complex process that involves negotiating technical, social, and ethical factors. While previous research has primarily focused on the reliability, composition, and validity of teachers’ grades, few studies have examined grading practices across cultural contexts and teaching subjects. The purpose of this exploratory study was to analyze how culture and teaching subject influence teachers’ grading dilemmas. Based on individual and group interviews with 11 Canadian and eight Swiss teachers, and using a “dilemmatic space” conceptual framework, this article inductively identified five dilemmatic spaces across cultural contexts and teaching subjects. The paper concludes with a discussion of the cross-cutting dimensions across these five dilemmatic spaces and articulates implications for future research and practice.
Writing therapy: paradox, peril and promise
Authors: Murphy Ffion
Published: July 2021

Belief in the remedial potential of the writing process has intensified in the past three

decades, with scientific studies indicating health and wellbeing benefits; poets, novelists

and memoirists proclaiming therapeutic effects; and, innovative and broad-ranging use

of creative writing in counselling and health care. This paper proposes that tertiary

writing education can benefit from the explicit study of writing therapy as a complex,

evolving and contested set of theories and practices. It outlines and contextualises my

own approach, discusses some relevant literature, and proposes future interdisciplinary

mixed-methods research, for the time is ripe in Australia for writing and health teachers

and researchers to work together to investigate writing’s risks, paradoxes and

recuperative possibilities.
Plot interrupted: reproducing the narrative benefits of trauma fiction in crime fiction
Authors: Dodd Leanne
Published: July 2021

Trauma distorts time and interrupts the natural flow of people’s life-stories. While

bibliotherapists may prescribe fictional stories to help clients internalise better coping

mechanisms and re-author their life stories, they rarely select crime fiction for this

purpose. This article demonstrates how crime writers can create works that may fit

the criteria for transformative therapy. Whitehead suggests that trauma fiction writers

have ’frequently found that the impact of trauma can only adequately be represented

by mimicking its forms and symptoms’ (2004: 3). By aligning the narrative strategies

used in trauma fiction to distort time, such as fragmentation and repetition, with those

strategies used in crime fiction, writers can develop a creative work that moves

beyond the prevailing conventions of crime fiction to incorporate the well-being

benefits of trauma fiction. The effect may transform perceptions and assist with

reconnection, while also providing a safe narrative space for all readers to work

through fears brought on by modern-day graphic exposure to traumatic events. This

research may prove significant in developing a framework to cultivate a form of

crime fiction that can direct readers into safe, controlled and custom-written

environments where they may better empathise, explore and experiment with their

responses to trauma.
Narratives of death and dying from one remove: surveying the undertaker’s memoir
Authors: Brien Donna Lee
Published: July 2021

While most book-length published memoirs on the topic of death and dying could be

broadly classified as illness memoirs, there are a surprising number of memoirs currently

in circulation whose narratives focus on the life and work of the undertaker. Despite

achieving a measure of popularity with readers, none of these works have been explored

(individually or as a group) in detail or categorised as a discrete sub-set of the

auto/biographical memoir. Surveying these narratives as a sub-genre of memoir – and

examining their modes of writing, publication and public reception – can contribute to

our understanding of both this revealing auto/biographical practice and practices of

writing and publishing popular memoir more generally. A way of categorising these

works is suggested, with representative memoirs in each category used as illustrative

examples. In suggesting that these texts are able to communicate to readers on the often

difficult topic of death and dying, this analysis serves to point to the power of

auto/biographical writing.
Lived experience and personal narrative: pathways to connection
Authors: Byrne Louise
Published: July 2021

First person narratives drawing on experiences in mental health settings and services

provide important insights into the lived experience of suffering, healing and recovery.

An emerging and influential role within mental health services is that of the ’lived

experience’ worker. People employed in what are known as ‘lived experience’ roles have

powerful stories to share. The use of personal narrative aids connection with current

service users, demonstrating that hope for a better life is possible and challenging

stereotypical or stigmatizing attitudes by highlighting shared humanity and common

human experiences. This article tells one such story, where parallel narratives and

multiple perspectives are used to highlight the benefit of encouraging vulnerability to

foster connection.
Using blogging to engage nursing students in reflective practice
Authors: Ryan Colleen , Heidke Penny , Blunt Nicole , Williamson Moira , Brien Donna Lee
Published: July 2021

Blogging is a practice that educators in creative and professional writing, journalism,

communication and a variety of other writing-based programs utilise to enhance their

students’ reflective writing, alongside other skills. This article suggests that this practice

may be useful in other non-writing based disciplines, in this case the discipline of nursing,

where reflective practice has been identified as a framework to assist in developing

personal growth, problem solving and the identification of innate strengths, allowing

professional maturation in difficult environments. It describes the use of blogging in an

assessment item in a final year undergraduate nursing unit. Analysis of students’ blogs

revealed blogging was cathartic and triggered reflection and transformation.

Os estudos empíricos sobre o movimento de resistência indígena Pipipã, por meio da educação escolar indígena, caminharam junto com a perspectiva do Pensamento Decolonial. Cada projeto político pedagógico desenvolvido para as escolas Pipipã orienta como os docentes devem trabalhar a formação dos futuros guerreiros e guerreiras, considerando alternativas para superar as tensões entre os conhecimentos originários do povo e as epistemologias impostas.
Does Road Traffic Congestion Increase Fuel Consumption of Households in Kathmandu City?
Authors: Bista Raghu , Paneru Surendra
Published: July 2021

The growth of vehicle and road traffic congestion is characteristics of urbanization and urban city and indicators of urban life in developing countries. In Nepal, non-economic factors and non-state factors have accelerated unexpectedly and haphazardly urbanization process, although the country was reengineered into seven provincial federal structure. In this backdrop, this paper empirically examines the growth of traffic congestion and its impact on urban households and livelihood based on 160 vehicle owners and users’ survey at six major traffic routes of two urban cities by applying mixed analytical methods (qualitative cum quantitative), descriptive statistics and multiple regression model. The descriptive statistics result of the study reveals nearly 94 percent acceptance level of vehicle owners and users about the growth of traffic congestion. Despite short distances of the road i.e. 2-4 kilometers and vehicle efficiency, the growth of traffic congestion increases 14036-liters fuel additional consumption. Per month, additional cost of fuel is estimated at 18,808 US dollars for a sum of distance i.e. 72,992 km between residence location and workplace each month. In the case of commuters, the estimation result of the study is 1188 hours of additional time loss with 6706 US dollars’ worth per month. The estimation of total economic loss is 25514 US dollars per month. Specifically, per month, economic loss of doctors and taxi drivers is 6556 US dollars but teachers and bankers have not economic loss.

Engagement With Active Learning: Reflections on the Experiences of Irish Accounting Students
Authors: Healy Margaret , McCutcheon Maeve
Published: July 2021

Accounting students have been characterised as being in the main extrinsically motivated, introverted surface learners, who may fail to achieve higher learning outcomes and are reluctant to engage in active learning. Using a phenomenological approach, this study considers how Irish accounting students engaged with active learning methods, recounting the benefits which arose and the difficulties encountered. Its findings demonstrate that the difficulties encountered related to the application of active learning methods, rather than the methods themselves; all students can potentially benefit from active learning if carefully introduced into their programme of study.

Freedom to Fail: The Impact of Giving Accounting Students the Chance to Fail at Questions
Authors: McWall Danielle , Wall Tony
Published: July 2021

Prior research demonstrates that student learning can be enhanced through self-guided reflection. In particular, promoting students’ metacognition and self-efficacy beliefs requires educators to provide students with opportunities to ‘be confused’, ask questions of themselves and build the resilience fundamental to their future professional lives. However, students cannot be expected to learn to learn; they must be taught how to learn. Additionally, they need to be assisted in identifying what learning strategies are available to them. Having outlined the rationale behind strategies such as student-led learning and student-driven assessment, this paper presents an analysis of student reflections, module evaluations and exam marks, and a comparison of final exam marks before and after a method known as freedom to fail (F2F) was introduced. It was found that the introduction of this approach led to a greater student awareness of learning strategies and improved results.
Terminological Framework for the Study of Circular Bioeconomy
Authors: Yaremova Maryna I.
Published: July 2021

In the context of increasing global environmental challenges associated with anthropogenic destructive impact on the environment, the bioeconomic direction of sustainable development in combination with a closed production cycle becomes relevant, the development of which would help to overcome the imbalance of the ecological and economic system and minimise the burden on the environment. Therefore, the purpose of this study is to comprehensively consider the prerequisites for the establishment of a framework of categories for combining green concepts of sustainable development, in particular, to substantiate the theoretical and methodological foundations for interpreting the fundamental features of circular bioeconomy to form a specific vision of the issue. The methodological basis of the study is general scientific and special theoretical and empirical methods, in particular inductive and deductive, heuristic method, graphic, analysis and synthesis, etc. At the empirical level, descriptive, comparative, and observational approaches are used. The theoretical level covers the historical, abstract-logical, hypothetical, formalisation method as a manifestation of logical thinking and theoretical generalisation for formulating the results of the study. This study systematises the ideas of leading scientists on the positioning of circular economy and bioeconomy, highlights similarities and differences in the process of combining concepts, identifies fundamental generic and specific features, establishes complementary relationships to generate the author's position and formulate a fundamental vision of the problems of circular bioeconomy. The practical significance of the study is conditioned by scientific substantiation of the terminological platform of the problems of circular bioeconomy. Further research is aimed at developing criteria for regulating the bioeconomic system with subsequent evaluation of results

The following models developed by Ukrainian researchers are identified: the model of a horizontally integrated business structure; the model of a vertically integrated business structure; the model of a globally integrated business structure; the model of a conglomerate-integrated business structure. The following models developed by foreign researchers are also summarised: a model for quantifying the impact of enterprise integration on the results of its activities; an information model; a model for designing and implementing an integrated enterprise system; a “three-lens” model; a business case model; a model for inter- and intra-organisational cooperation
Open Land Market in Ukraine: Pragmatics of the Phenomenon through the Lens of European Experience
Authors: Sosiedko Kateryna D. , Palmieri Marco
Published: July 2021

The relevance of the study is conditioned by the fact that the violation of land ownership rights and the moratorium on the purchase and sale of land plots limit the development of the national economy in general and the land market in particular, contributing to the operation of shadow agribusiness. However, starting from 01.07.2021, all restrictions on the sale of agricultural land are lifted, and new opportunities and threats arise. The purpose of the study is to analyse the new legislation regulating the launch of an open land market in Ukraine. To obtain scientific results, the following methods are used: dialectical, comparison, analogies and comparisons, monographic, benchmarking, expert evaluation method, SWOT analysis, forecasting method, analysis and synthesis. In accordance with this, the current state of land in Ukraine and European countries is considered. The existing land market in Ukraine and the world is analysed. A historical retrospective inquiry of events related to the lifting of the land moratorium is carried out. The law that ensures the launch of an open land market is characterised. Significant additions are identified in the law between the first and second readings. The mechanism of regulating the launch of the Ukrainian open land market is clarified. This study considers the international experience of operation of the open-type land market and reflects competitive prices for 1 hectare of land in comparison with Ukraine. According to this, the positive impact of land reform in European countries is determined. The main factors of effectiveness of the open land market model in foreign countries are presented. The main opportunities and threats for an open land market in Ukraine are analysed. The findings of the study reflect both the positive and negative consequences of launching an open market in Ukraine, citing expert opinions of supporters and opponents of such a market transformation
THE EFFECT OF TEMPERATURE AND TIME ON THE MIGRATION OF LEAD METAL (PB) IONS IN CANNED ORANGE JUICE DRINK USING ATOMIC ABSORPTION SPECTROPHOTOMETRY ANALYSIS

Published: July 2021

Background: Indonesia is a country that has a tropical climate throughout the year along with relatively less difference of temperature during both dry and rainy seasons. The mobile community influences people’s interest in packaged drinks, including canned fruit juice. However, the first obstacle is the condition of the place and the temperature-related heavy metal lead (Pb) migration in canned orange juice drinks. Methods: This study focused on the relationship between Pb metal content, storage treatment, storage temperature, and storage time. This study used a canned orange juice drink from the distributor warehouse of Palembang city, standard Pb(NO3)2 (Merck) powder, 0.5 mol/l concentrated HNO3 solutions (Merck), concentrated HCl solution (Merck), demineralized water, Buffer pH 4.7, and 10. The sample was conducted from 5 °C to 40 °C with the testing period within 1-30 days. The sample at certain day intervals would then be tested to change pH and Pb ion concentration using the Atomic Absorption Spectrophotometry (AAS) test. Results and Discussion: In this study, the sample of orange juice was given different treatments, and each treatment has a differentiated analysis code consisting of S-SBJ-1-1 (Distributor warehouse) for one day of storage time, and the codes for 10 of storage time are SSBJ-10-1 (Freezer, temperature 5 °C), S-SJB-10-2 (Refrigerator, temperature 20 °C), S-SJB-10-3 (Homeroom, temperature 28 °C), S-SJB-10-4 (Oven, temperature 40 °C), S-SJB-10-5 (Open space, temperature 22°C - 38 °C). Furthermore, codes for 30 days of sample storage are S-SBJ-30-1 (Freezer, temperature 5 °C), S-SJB-30-2 (Refrigerator, temperature 20 °C), S-SJB-30-3 (Room house, temperature 28 °C, S-SJB-30-4 (Oven, temperature 40°C), and S-SJB-30-5 (Open space, temperature 22 °C-38 °C). Conclusions: Temperature and time have a significant influence on the migration of the heavy metal lead (Pb) from the can to orange juice drinks, and, for the minimum pH value, there is a less significant change. Overall, canned fruit juice should be stored at a temperature below 28 °C, and the drink is protected from direct sunlight and high humidity.

Background: Periodontal infection leads to adverse pregnancy outcomes such as preterm delivery, low birth weight, preeclampsia, miscarriage, or early pregnancy loss. Aim: The aim of this study was to investigate the knowledge, attitude, and practice of pregnant women about periodontal health and oral health and their effect on the fetus. Methods: The present study is a descriptive-analytical study on 210 pregnant women in the first and second trimesters referring to health centers in Birjand in 2019. The tool used in this study was a researchermade questionnaire with four parts: women's demographic information, and women's knowledge, attitude, and practice, the validity, and reliability of which were confirmed. After data collection, it was entered into SPSS software version 22 and then analyzed using descriptive statistics, independent t-test, and one-way analysis of variance. The significance level was considered 0.05 in all tests. Results and Discussion: In this study, the mean scores of knowledge, attitude, and practice of pregnant women were 5.6 ±1.92, 55.9 ± 5.1, and 25.9± 3.7, respectively. There was a significant difference between the mean attitude score and mothers' age. There was also a significant difference between the mean scores of knowledge, attitude, and practice of women and significant difference in knowledge, attitude, and practice of employee and housewife pregnant women; In terms practice, there were significant differences between pregnant housewives and self-employed women. There was a significant relationship between the mean of these scores and mothers' jobs so that the mean scores were higher in employed women than others. Conclusions: The results of our study showed that the average score of knowledge, attitude, and practice of pregnant women in Birjand regarding oral hygiene during pregnancy is not satisfactory and appropriate.

Background: Moringa oleifera seed, which is widely utilized as an affordable source of domestic water treatment, is also reputable for its various pharmacological applications globally. Aim: This study evaluates the toxicity and pharmacological potentials of Moringa oleifera seed protein while establishing the chemical profile. Method: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and liquid chromatography coupled with electrospray ionization mass spectrometry (LC-ESI-MS/MS) were used to analyze the protein/peptide content of the purified protein. The protein was also investigated for in vitro anticancer potential on Hela and MDA-MB-231 cell lines, cytotoxic on 3T3 cell line, and toxicity to brine shrimps. In addition, the antimicrobial action of the protein (polypeptide) was evaluated. Results and Discussion: The MALDI-MS revealed three protein moieties with values of 3.4, 4.6, and 6.9 kDa. On the other hand, LC-ESIMS/MS analysis revealed dipeptides and tripeptides, which include serinylarginine, leucylproline, leucylmethionyl-glycine, isoleucyl-glycyl-methinine, glycyl-arginyl-aspartic acid, isoleucyl-glutamyl-methionine, diphenylalanine, asparaginyl-aspartyl-histidine, seryl-tyrosyl-tyrosine, phenylalanyl-asparaginyl-tyrosine, and propanolyl-trytophanyl-glycine. The seed protein exhibited extremely low toxicity on both 3T3 and MDA-MB-231 breast cancer cell lines, while the standards, doxorubicin, and cycloheximide had IC50 = 0.5 ± 0.07 and 0.8 ± 0.10 μg/mL, respectively. Further, the protein showed no antibacterial or antifungal activity against all tested organisms. The protein also exhibited no lethality against brine shrimp. The in-silico toxicity results indicated that the peptides are not immunotoxic, carcinogenic, or mutagenic as most belonged to the tox class V except serylarginine predicted for tox class IV (harmful if swallowed). Hence, the intake of the protein remnant in water could be within the tolerable limit. Conclusion: The results obtained suggested that the protein content of the Moringa oleifera seed is non-cytotoxic. The result further validates the safety potential of the defatted and debittered seed material used as potential food sources for both humans and animals.

Background: Wastewater from the mineral fertilizer production, agribusiness containing ammonium ions causes significant harm to fish farming; therefore, it must be purified before discharge. Ion-exchange sorption is a promising method for isolating ammonium cations. The object of the study was a chemisorption fiber VION KN-1, which has developed surface and high sorption rate. Purpose: To study the sorption kinetics of ammonium cations from aqueous solutions on VION KN-1; to train an ANN to predict the degree of recovery of ammonium ions from wastewater using Statistica Neural Networks Version 13. Methods: The ammonium ion concentration in the solution was established by direct potentiometry. Sorption isotherms were constructed using the method of variable concentrations. To determine the limiting stage, the obtained kinetic dependencies were represented in the coordinates of the Boyd-Adamson equations for internal/external diffusion. Results and Discussion: During sorption from solutions with different ammonium nitrogen contents, the values of distribution coefficients (Kd) are at the level of 2.3ꞏ103 cm3/g, which significantly exceeds this parameter for granular ionites. Experimental sorption data were verified using Freundlich (R2 = 0.9224) and Langmuir (R2 = 0.9996) isotherms. The maximum degree of recovery (over 96 %) was achieved by passing a solution with a concentration of 11.3 mmol/dm3. Using an array of experimental data, the MLP-3-5-1 neural network was trained. The coefficient of determination R2 = 0.999420 obtained for the training sample characterizes high network performance. Conclusions: The Langmuir equation better describes the process of NH4+ sorption on a fibrous sorbent. It is reasonable to use VION KN-1 at the fine treatment stage. Ammonium ion desorption from the fiber was performed by acid solution. The resulting solutions of ammonium salts can be used as liquid fertilizers. The trained neural networks can be used to predict the degree of recovery of ammonium ions by sorbent VION KN-1.

Authors: Boamah Valentina
Published: July 2021

Oil plays a vital role in the economic growth and sustainability of industries and their corporations. The current study sought to forecast oil demand in Ghana for the next decade. The variables analyzed in this study were Petroleum and other liquids, motor gasoline, distillate fuel, and liquefied petroleum gases (LPG). The study utilized three univariate models; thus, linear regression, exponential regression, and exponential smoothing for forecasting various oil components. The linear regression model was deemed a better fit for the analysis of most of the variables. Furthermore, the findings revealed that the LPG growth rate is faster and requires less time to double in numbers than the other energy sources. Also, the exponential smoothing model was ineffective and inefficient. Overall, the demand for oil components analyzed will follow an increasing pattern from 2017 to 2027.
