Published: July 2021

Abstract
Long-distance water transfer projects are important for water allocation. To enhance our understanding of biofilm growth and changes in water quality during raw water transfer, raw water through a long-distance non-full culvert at flow rates of 1.4−2.0 m/s was studied. The results revealed that: (1) the biofilm total cell count (TCC) and heterotrophic plate count (HPC) were the highest at a flow rate of 1.5 m/s, which were 3.7 × 104 cells/cm2 and 1.1 × 103 CFU/cm2, respectively; (2) Proteobacteria had the highest relative abundance (RA) among all samples, and the RA in biofilm (78.85%) was higher than that in water (48%−59%); (3) when the pollutants and biofilm were partially shed, the total phosphorus (TP), permanganate index (CODMn), and dissolved organic carbon (DOC) increased by 0.011, 0.36, and 0.5 mg/L at most, respectively; and (4) dissolved oxygen (DO) was sufficient during non-full flow water transport and nitrification occurred. The highest removal rates of ammonium nitrogen (NH+4-N) and nitrous nitrogen (-N) reached 27.16% and 66.76%, respectively. At the flow rates of 2.0 m/s, the efficiency decreased to 10.47% and 41.25%, respectively, due to the shedding of biofilm.

Published: July 2021

Abstract
With the successful development of shale gas in the United States, shale gas has become an effective way to solve the energy crisis. Among a series of environmental problems caused by shale gas exploitation, the most hidden and the most difficult part to control and recover is groundwater pollution in the development zone, which has been paid more and more attention by the government and the public. Starting from the shale gas exploitation process, this paper discusses the research status and problems of shale gas exploitation on groundwater pollution prevention and control from both international and domestic Chinese directions, and considers the future development of groundwater prevention and control work: to strengthen the supervision and management of wastewater treatment; to explore and evaluate shale gas resources and to plan regional water resources; to update and improve relevant environmental laws to strengthen the support for shale gas development; to make public supervision and development transparent; and to optimize the whole development process.

Published: July 2021

O texto tem como objetivo principal analisar a representação de três personagens femininas em contos destinados ao público infantil e juvenil, com temática africana. Para tanto, foi escolhido o livro Ulomma – A casa da beleza e outros contos, do escritor nigeriano Sunny e ilustrado por Denise Nascimento. Parte-se do reconhecimento da importância dos estudos clássicos sobre contos de fadas e literatura infantil e juvenil, todavia a análise apresentada assume uma perspectiva afrocentrada, buscando a importância da palavra nas culturas africanas e afro-brasileira, o papel das narrativas nas sociedades africanas, onde a oralidade é um elemento central na produção e manutenção das mais diversas culturas, dos valores, conhecimentos, ciência, história, modos de vida, formas de compreender a realidade, religiosidade, arte e ludicidade. O segundo ponto de análise será a representação das personagens femininas, sendo um bloco para cada personagem. A análise se dá tanto do ponto de vista imagético, quanto da construção discursiva via enredo da narrativa, objetivando localizar nos contos a questão das tradições e dos papéis femininos, a maternidade, as relações entre o ser humano e a natureza, o sagrado, relações de poder e principalmente a valorização estética negra. O artigo é finalizado com questionamentos sobre os caminhos que os textos dirigidos ao público infantil e juvenil percorreram para chegarem até nós, indicando que a necessidade de construção e rotas alternativas para a compreensão dos mesmos.

Published: July 2021

Abstract
This study is a continuation of the series of summaries by the Green Industry Research Consortium examining the regional trade flows in the U.S. nursery industry. This detailed analysis of green industry regional trade flows in eight U.S. regions compares 2018 data with those of the 2008 and 2013 national survey estimates of origin and destination (OD) information to sales data. Specifically, we discuss: 1) regional annual sales reported by the green industry firms in 2018, 2) the percentage distribution of OD trade flows by regions and states, 3) differences in the percentage distribution of OD trade flows during the 5-year period by region (2013 to 2018), and 4) differences in the percentage distribution of OD trade flows during the 10-year period by region (2008 to 2018) for both intra-state (within home state) and inter-regional (between states) trade flows. The OD trade flow results were compared with those of 2008 and 2013. The results show considerable changes in intra-state and inter-regional trade flows from 2013 to 2018. From 2008 to 2018, only the Southcentral region increased in the proportion of sales within the region. Implications for relevant green industry stakeholders are discussed.

<p>Coffee is one of the leading commodities in the plantation sub-sector in Indonesia because it has good market opportunities both locally and globally. The purpose of this research was to find out how the effect of perceived product similarity, product choices overload in the market toward decisions making difficulty, and knowledge of product classes as moderating variable. Data were collected using Google Forms and a self-administered questionnaire. Respondents in this study were 300 coffee consumers which were drawn using the purposive sampling method. Moderated regression was used to analyze this study. The results showed that perceived product similarity influences product choices overload positively and decision-making difficulties negatively. Choice overload had an insignificant effect on decision-making difficulties, and product class knowledge moderates the effect of perceived product similarity on decision-making difficulty. These findings provide insight into the importance of the brand as a distinguishing identity from other products.</p>
FIRST YEAR COMMUNICATIONS CLASSES: APPLICATIONS OF CRITICAL EVALUATION OF INFORMATION IN A PROBLEM-BASED LEARNING FRAMEWORK
Authors: Mercer Kate , Weaver Kari , Lamont George , Moffatt Christine 
Published: July 2021

Increasingly in an information-centric society, educational institutions must navigate ideological and pragmatic approaches to teaching how and where students find information used to make decisions. Engineering students’ information-seeking needs must also navigate a variety of competing sources of information—their professors, the library, their peers, family and friends, and industry professionals. Undergraduate engineering students are faced with learning both fundamental engineering concepts and soft skills such as information seeking and communication. One approach to teaching information seeking and communication could beProblem-Based Learning (PBL), which is a teaching method focused on having groups use open-ended realworld problems as a context for learning new concepts. This paper will provide a summary of the current scope of literature around PBL, implications for sustainability, andcontextualize it within the multidisciplinary context of library-focused interventions in first year communications courses.
Occurrence and probable source of chromium enrichment in Permian coals, South Africa
Authors: Wagner N.J. , Mokwena M.L. , Kolker A. 
Published: July 2021

AbstractThe trace element data pool for South African coals is limited. However, certain elements are reported as occurring in considerably higher concentrations than global average values. These elements include chromium (Cr), as well as manganese (Mn), cobalt (Co), and molybdenum (Mo), with Cr showing the most consistent enrichment. The aim of this study was to investigate the occurrence of Cr in South African coals sampled from five coalfields, and to assess the possible source of Cr. A total of 21 run-of-mine (ROM) coal samples from the Waterberg, Soutpansberg, Witbank, Highveld, and the Nongoma Coalfields were obtained from active mines. Coal characterization, mineralogy, and geochemical data were compiled. The Cr values for the Waterberg (23 to 28 ppm), Soutpansberg (4.7 to 43 ppm), Witbank (24 to 37 ppm), and Highveld (33 to 37 ppm) coal samples are higher than those for the Nongoma coals (1.2 to 2.5 ppm), and, in nearly every case, higher than the Clarke value for hard coals (17 ppm). Correlation coefficients, density fractionation, and selective leaching were used to infer (indirect) modes of occurrence. A dominant silicate (clay) affinity was determined with Cr, as well as an organic affinity in the ROM samples. The Nongoma coals, with illite and no kaolinite, have extremely low Cr values. The other samples are enriched in kaolinite and also have a high Cr content. Chromium values as high as 67 ppm were reported for 1.4 RD float fraction samples, indicating a positive correlation with organic matter. A Cr - silicate association was observed following selective leaching. These results imply multiple modes of occurrence of Cr in the South African samples, in agreement with studies conducted globally. Chromium in the South African coals could have originated from the Bushveld Complex (approximately two billion years old), the largest Cr reserve in South Africa, which predates coal formation (approximately 299 to 252 million years ago) and is proximal to the coalfields. The Cr, seemingly not associated with chromite, may have been redistributed in the peat swamps during peat deposition, accumulating in the sediments and organic material. The Nongoma Coalfield is the farthest distance from the possible Bushveld Complex Cr source, and these samples are depleted in Cr.
An overview of high-performance computing using the residue number system
Authors: Исупов Константин Сергеевич 
Published: July 2021

Система остаточных классов (СОК) — это непозиционная система счисления, являющаяся альтернативой двоичному представлению чисел. В СОК большое целое число представляется в виде набора меньших чисел, являющихся остатками от деления исходной величины на выбранные модули. СОК выполняет сложение, вычитание и умножение с каждым остатком по отдельности. Это приводит к параллельной, свободной от переносов и высокоскоростной компьютерной арифметике для высокопроизводительных вычислений. Однако немодульные операции, требующие оценки величины числа по остаткам, являются сложными для реализации в СОК, так как для них не существует параллельной формы. В вопросах практического использования СОК выполнение немодульных операций занимает центральное место.
Представлен обзор исследований в области разработки и применения на практике методов высокопроизводительных вычислений на основе СОК: Рассмотрены существующие техники выполнения важнейших немодульных операций, таких как обратное преобразование, сравнение чисел, вычисление знака и деление. Акцент сделан на методы, пригодные для произвольных наборов модулей. Показано, каким образом арифметика на основе СОК находит практическое применение в облачных средах, блокчейн-технологиях, вычислениях многократной точности и глубоких нейронных сетях.
Обзор ориентирован на развитие новых направлений исследований, посвященных применению непозиционных систем счисления с параллельной структурой в ресурсоемких приложениях.
