Organic matter parameters in WWTP – a critical review and recommendations for application in activated sludge modelling
Authors: Ahnert Markus , Schalk Thomas , Brückner Heike , Effenberger Johannes , Kuehn Volker , Krebs Peter 
Published: September 2021

Abstract
This paper includes a comprehensive literature review of sludge composition data from wastewater treatment plants. 722 data sets from 249 sources were used to establish typical ratios between COD and solids-based parameters and to verify rule-of-thumb values, respectively. Confirmation of these typical ratios can also be accomplished by using biochemical composition data. It is shown that a correlation between data from proteins, lipids and carbohydrates analysis can be related to COD/VSS ratios. Finally, using the findings from the literature review, the organic and inorganic conversion factors of COD fractions in activated sludge models are adjusted to solids-based parameters. It was shown that with the adjustments of the factors and a partition of the particulate inert fraction into a fraction assigned to the influent and a fraction assigned to the endogenous products, a better agreement with the ratios of COD/VSS in the individual sludge streams can be established.

Published: September 2021

O presente artigo tem como objetivo apresentar um balanço do que foi produzido em trabalhos científicos na área de Educação Infantil na primeira década após a promulgação das Diretrizes Curriculares Nacionais para a Educação Infantil - DCNEI (BRASIL, 2009). Seu principal aporte teórico é Leontiev (1978), que defende a ideia que é através da educação que o homem torna-se humano em sua essência. Resulta de uma pesquisa do tipo “Estado da Arte” que, através de uma metodologia inventariante e descritiva, fez o levantamento das produções acadêmicas sobre as DCNEI (BRASIL, 2009) no período de 2010 a 2020 em três plataformas eletrônicas: Catálogo de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES, Google Acadêmico e ResearchGate. Seus resultados apontam os temas de maior destaque nas pesquisas e que envolvem a compreensão de currículo em sua episteme, perpassando por reflexões acerca das teorias, concepções e conceitos que o compõem. Em contrapartida, assuntos como o brincar, as interações, a educação para as relações étnico-raciais, a avaliação e a prática com bebês, fundamentais para a efetivação de um currículo que considere a criança como centro, ainda são pouco explorados ou sequer aparecem entre os temas focalizados. Além disso, evidenciam inúmeros desafios que precisam ser enfrentados pela comunidade acadêmico-científica em relação ao currículo na Educação Infantil e suas especificidades, o que possibilita a ampliação dos debates sobre o tema.

This research executed in Siberut island which has been specified Unesco as Biosphere Reserve. The purpose of research was to identify the policy which has been specified in Siberut, knows implementation of management, knows perception and participation of public and knows interaction of the parties involving in management Biosphere Reserve. Method applied is Inventory and contents analysis of policy, Indepth Interview with cross check, Open interview with descriptive qualitative and Inventory and Stakeholder analysis. Republic of Indonesia Government doesn't support expansion of Siberut Biosphere Reserve for all island. There is understanding difference and exploiting of Biosphere Reserve according to the Government with MAB-UNESCO so do with perception there are difference between publics Siberut with the Government. Local public assumes that forest Siberut is custom forest which its the domination stays at custom public according to custom Arat Sabulungan, where its the exploiting and management is done based on custom, but the Government considers to be state forest. Implementation of Siberut Biosphere Reserve Pledge based on Indicator Implementation released by Unesco, 1996 till now still uncommitting for overall of area Biosphere Reserve, except to of Core area (Siberut National Park). Implementation at core area based on Indicator Implementation (Unesco, 1996) mostly has been executed, except for Indikator 5,6,8,9 and 16. Role and influence MAB and TNS in Siberut still be low for the reason need to be improved.

Zircon geochronology and geochemistry of pre-Bushveld sills in the eastern Transvaal Supergroup, South Africa
Authors: Bolhar R. , Cawthorn R.G. 
Published: September 2021

Abstract
An extensive suite of sills occurring in the eastern and western Transvaal Supergroup has been termed the Marico Diabase Suite. As a result of their overall geographic proximity to the Bushveld Complex and occurrence in the Transvaal Supergroup they have been assumed to be related to the Bushveld Complex. Previous studies have identified two different types of rocks within this suite, namely the Maruleng and Lydenburg types, based on geochemical and metamorphic characteristics. The Maruleng type has mineralogical (orthopyroxene-bearing) and geochemical affinities with the mafic rocks of the Bushveld Complex, and rocks belonging to this type are much more closely spatially related to the Bushveld Complex. The Lydenburg type, on the other hand, is much more extensive spatially and was emplaced at variable depths within the Transvaal Supergroup. The latter type of rock is variably metamorphosed, far beyond the likely thermal effects arising from emplacement of the Bushveld Complex. Using LA-SF-ICPMS and LA-MC-ICMS for U-Pb-Hf isotope ratio and REE+Ti concentration analysis, we demonstrate that zircon grains from this latter type were subjected to hydrothermal alteration, which caused the introduction of common lead. Despite compositional and isotopic overprinting, an age of 2 083 ± 18 Ma (MSWD = 12, n = 16) is obtained, suggesting a pre-Bushveld in age.
We suggest that the original term Marico Diabase Suite encompasses two different events. The Maruleng Suite should be grouped as part of the Bushveld Complex, whereas the Lydenburg Suite should be given a status that is independent from the Bushveld event.
Is percutaneous radiologic gastrostomy safer than percutaneous endoscopic gastrostomy?
Authors: Righetti Johnathan , Morris Shane , Fotoohi Mehran , La Selva Danielle , Zehr Troy , Kozarek Richard 
Published: September 2021

Objectives:
The objectives of the study were to compare the indications, adverse events, removal rates, and mortality of percutaneous endoscopic gastrostomy (PEG) and percutaneous radiologic gastrostomy (PRG) techniques at our tertiary care institution from 2014 to 2019.

Material and Methods:
We undertook a 5-year retrospective review of patients who underwent either PEG or PRG at our institution from 2014 to 2019. Common adverse events include tube clogs, leaks, minor bleeds, and wound infections, while more rare major complications include peritonitis, intra-abdominal infection, and major hemorrhage. The procedures were all performed with either conscious sedation or general anesthesia. A total of 789 patients were reviewed, of whom 519 (65.8%) had a PRG and 270 (34.2%) had a PEG. PRGs were more likely to be placed for head-and-neck cancer (P < 0.0001) and amyotrophic lateral sclerosis (P < 0.0001), while PEGs were more likely to be placed for gastric outlet obstruction (GOO) (P <.0001) and malnutrition (P < 0.0001).

Results:
The rate of major adverse events was similar between the two groups (P = 0.938). GI placed gastrostomy tubes were more likely to have a minor adverse event (P < 0.0001), however, this was secondary to a significant increase in tube clog in the PEG/J group as compared to PEG (P < 0.0001).

Conclusion:
The decision to place a PEG or PRG should be individualized to the patient’s specific condition and indication. Both procedures have favorable safety profiles, and it is likely that institutional expertise and procedural access will be the primary determinants of the procedural technique chosen for minimally invasive gastrostomy.

Biosensor devices including hybrid nanostructures as modifiers of transducer surfaces meet current requirements for the methods of research and determination of drugs, including antidepressants. The fea­tures of amperometric monoamine oxidase biosensors based on printed carbon electrodes modified with nanocomposite compositions C60 / cobalt nanoparticles/amino derivative of polyether polyol of the second generation/chitosan nanocomposite structures used for the detection of tricyclic antidepressant amitriptyline are considered. The choice of the best modifier was made proceeding from the data of transmission electron microscopy, scanning electron microscopy, electrochemical impedance spectroscopy, and differential pulse voltammetry. When developing the biosensor, conditions for depositing the composite composition of cobalt nanoparticles/amino derivative of polyether polyol on the electrode surface were varied: electrochemical deposition, sequential layer-by-layer deposition, and deposition of the mixture. The peak of electrochemical oxidation of hydrogen peroxide, which is formed during the enzymatic reaction of serotonin oxidation under the action of monoamine oxidase was used as an analytical signal of the biosensor. The principle of the biosensor action is based on the inhibitory effect of amitriptyline on the catalytic activity of immobilized monoamine oxidase. The proper choice of a modifier and optimal working conditions provided the range of detectable concentrations of amitriptyline: 1 x 10-4 - 1 x 10-8 M, the lower limit of the determined content at a level of 5 x 10-9 M for monoamine oxidase biosensor. Comparison of the results on the amitriptyline content determination in the pharmaceutical preparation and urine obtained using the monoamine oxidase biosensor and polarization fluorescence immunoassay (dilution of the tracer 1:32, dilution of antibodies 1:128, the range of working concentrations 5 x 10 -8 — 5 x 10-9 M), well-proven in the quantitative determination of medicinal substance, confirmed the correctness of the results obtained.

Measuring Student Involvement When Taking Tests in E-learning Courses
Authors: Dziedzic Krzysztof 
Published: September 2021

The ongoing SARS-CoV-2 pandemic has significantly affected the education process of young people in primary, secondary, and tertiary education, as well as those who improve their competences through various courses and trainings. The practically incessant lockdown in education has resulted in a situation in which distance learning, which most often plays a supplementary role, now constitutes the basic form of education. This situation has forced the selection and adaptation of the available e-learning tools to the types of classes and levels of education. Despite great progress in the development of e-learning technologies, constant stimulation and maintenance of students’ interest in the content presented and monitoring their activity still pose a problem, which also concerns the education of computer science students in issues related to computer graphics. Currently, the preferred model of distance learning is based on various technologies and IT tools that enable the implementation of synchronous and asynchronous work. Prompt acquisition of data on students’ activity allows trainers to adjust the form and content of the presented material to their expectations. It also makes it possible to identify issues that pose great difficulties to students. This paper discusses modern solutions and trends in designing e-learning courses based on the new interactive e-learning platform Quizer. The aim of the research is to determine the course effectiveness using the user activity-monitoring module designed and implemented for the Quizer e-learning platform. The correctness of the answers correlates with the number of attempts to answer it (−0.65). The time devoted to a given question was usually high for questions with low correctness of answers.
