The Australian non-profit sector and the challenge of ICT
Authors: Denison Tom , Stillman Larry , Johanson Graeme
Published: March 2020

In recent years, the Australian Government has been encouraging the adoption of information and communications technologies (ICT) by non-profit organisations. In 2006, as a part of that process, the Government initiated a project to develop a possible model and business plan for a National Non-profit ICT Coalition (NNIC), conceived of as a coalition of leading non-profit organisations and social enterprises that would assist the sector in making more effective use of ICT. This paper draws on data collected during an extensive consultation process conducted to inform that model, and examines the data in terms of the response of non-profit organisations to the challenge of ICT within an Australian context. It then considers the implications for both the management of non-profit organisations and government policy.
Simulating Continuous Counter-Current Leaching Process for Indirect Mineral Carbonation Under Microwave Irradiation
Authors: Tong Zhibo , Ma Guojun , Zhou Dan
Published: March 2020

Mineral carbonation is a promising avenue to realize a deep reduction in carbon dioxide emissions. Though many methods were studied to improve the leaching ratio of mineral leached by ammonium salt, little attention has been received to the problem that the calcium leaching ratio increases
while its concentration drops rapidly with the liquid-solid ratio increasing. The continuous counter-current leaching for mineral carbonation process under microwave irradiation is proposed in this study, and the results show that the simulating continuous counter-current leaching process
in this article not only is beneficial to improve the leaching ratio and concentration of calcium ions in solution at the same time, but also increases the relative purity of calcium in leached solution. And the produced calcium carbonate products meet the requirements of industrial precipitation
of calcium carbonate.
Recycled PVC as Material for Natural Fiber Composite Manufacturing—study of Mechanical Performance and Durability
Authors: Irina Turku , Timo Kärki
Published: March 2020

Manufacturing wood plastic composites from polyvinyl chloride (PVC) construction waste is one of the options for its continuously increasing scrap utilization. The aim of this study is to estimate the mechanical properties and durability of composites manufactured from recycled and
commercially available PVC grades. The mechanical properties of PVC were reduced significantly after wood flour loading, showing weak compatibility between the matrix and the wood fibers. The composites from both PVC sources had weak durability, declining by up to 64% in tensile strength.
The composite samples from recycled PVC displayed, however, better resistance to weathering compared to the composites from neat PVC. Chemical analysis of the composite surfaces by infrared spectroscopy and morphology study with a scan electron microscope before and after weathering confirmed
the mechanical test results.
Effect of Incorporating Tire Rubber Waste on the Mechanical Behaviour of Railway Ballast Layer: Experimental and Modelling Studies
Authors: Jemaa Hafsa Ben , El Euch Khay Saloua , Loulizi Amara , Neji Jamel
Published: March 2020

In order to delay the degradation of railway tracks, several techniques have been developed in recent years; the best known of which are: under sleeper pads, geogrid and the use of polymers as elastic elements between ballast particles. The objective of the research described in this
paper is to evaluate the effectiveness of incorporating tire rubber waste into the ballast layer in reducing its settlement. For that purpose, a small-scale testing laboratory setup has been developed, which consists of a bi-block concrete sleeper surrounded by a layer of ballast. The developed
apparatus is subjected, through the actuator of a servo-hydraulic machine, to a vertical cyclic force reproducing the passage of a train bogie. This study has been performed in two stages: the first is to identify a suitable existing model that well-describes the ballast settlement with cycle
applications and the second is to study the influence of the variation of the percentages of addition of rubber on the behaviour of the ballast layer. Finally, a finite element model was developed to simulate the experimental setup. The results show that using 10% of tire waste rubber could
decrease the track settlement and reduce the breakage of ballast particles.

Using Insights in Sen’ Capability Approach to Overcome Empirical Development Ethics Research Designing and Execution Challenges
Authors: Mazigo Almas , Hattingh Johan
Published: March 2020

In this paper, we support the adoption of an empirical approach in development ethics research and show that the theoretical insights and methodological guidelines in Sen’s capability approach (CA) can offer helpful guidance to development ethicists on designing and execution of such research. To this end, we show how specific insights in the CA guide one to identify and engage with relevant stakeholders in extensive dialogues about the ethical issues underlying their development practices and in gathering empirical data for further ethical reflections. Drawing on an empirical development ethics research project we conducted in the fisheries sector of Ukerewe District in Tanzania, we illustrate how the CA supported us in identifying 310 representatives of various categories of small-scale fishers and stakeholders, and in designing and executing empirical development ethics research in the form of progressive stages of dialogues in stakeholder groups. The participants in these stakeholder groups reflected on and assessed their individual and collective values, capacities, roles and interests in the fisheries sector. In turn, we gathered empirical data on (i) the nature and causes of the poverty of small-scale fishers and ways to overcome it, (ii) the moral roots of the prevalence of institutional and professional apathy, and (iii) stakeholders’ motivations and concrete actions to support the redressing of the challenges facing small-scale fishers. Later, we used these empirical data to theorise about moving small-scale fishers from poverty to prosperity, and about the development ethic best suited to guide future initiatives in combatting poverty and generating wealth through the fisheries sector in Ukerewe District.

De manera independiente de 14 que se practiqu4 se puede afirmar de forma categórica que la Biblia como texto, es abundante en enseñanzas para la vida cotidiana del género humano, las cuales Bien pueden aplicarse a las áreas de acción de los ejes transversales que el currículo escolar se propone trabajar. Estas enseñanzas fluyen cuando recurrimos de forma especial a los libros de los profetas, la literatura sapiencial (Salmas Proverbios Eclesiastés.), las cartas paulinas, las cartas pastorales y/o las cartas apostólicas. Pero, para efectos de este trabajo, el tema se ha circunscrito a las enseñanzas del evangelio de Jesús. De ahí que el objetivo de este escrito sea el de establecer una relación bien directa entre el currículo escolar y el evangelio de Jesucristo, de tal manera que se vislumbre la pertinencia de ambos elementos, para el establecimiento de buenas y sanas relaciones interpersonales en la sociedad de hoy.

Multiple S Isotopes and S Isotope Heterogeneity at the East Eagle Ni-Cu-Platinum Group Element Deposit, Northern Michigan
Authors: Benson E.K. , Ripley E.M. , Li C. , Underwood B.W. , Mahin R.
Published: March 2020

The East Eagle Ni-Cu-platinum group element deposit is a conduit-type deposit located in northern Michigan, in close spatial proximity to the currently producing Eagle deposit. Massive and semimassive (net-textured) sulfide mineralization at East Eagle occurs approximately 800 m lower in the stratigraphic sequence than that at Eagle and only ~200 m above the contact between Proterozoic and Archean rocks. Although sulfide mineralogy and textural types are similar at the two occurrences, there are important differences in their S isotope systematics. Massive sulfide mineralization at East Eagle is characterized by a relatively narrow range of δ34S values from 1.5 to 3.2‰. Semimassive sulfides show a similar range from 2.1 to 3.8‰. In strong contrast to these values, those from disseminated sulfides that border the massive and semimassive mineralization define a much larger range from –4.3 to 22.8‰. The much more restricted range in δ34S values recorded in the massive and semimassive sulfide mineralization compared to that of the disseminated mineralization is thought to reflect isotopic exchange reactions in the conduit involving accumulated sulfide and pulses of magma containing S of mantle origin. The ∆33S values of all three major types of sulfide mineralization at East Eagle are near 0‰, with most values between –0.03 and 0.03‰. Unlike ∆33S values from semimassive sulfide mineralization at Eagle, the ∆33S values at East Eagle show no, or very limited, evidence for the involvement of S derived from Archean sedimentary rocks. The wide range in δ34S values recorded in the disseminated mineralization provides strong evidence that S from Proterozoic sedimentary host rocks was involved in the mineralization; in some cases, as much as 85% of the S may have been of external origin. In addition to the wide range in δ34S values, the disseminated mineralization is characterized by spatially heterogeneous δ34S values. Meter-scale S isotope variations, as well as variations in Pt and Pd tenor, are consistent with multiple inputs of magma, each characterized by distinct S isotope ratios. Heterogeneity of several per mill at the centimeter scale indicates that the degree of supercooling exceeded the S diffusivity, preserving small-scale S isotope variability inherited from the sedimentary country-rock source. Elongate, branching plagioclase grains in many of the gabbroic rocks that host the disseminated sulfide mineralization are consistent with a rapid second stage of cooling.

Published: March 2020

Despite the restrictions and controversies in Turkey’s educational system, the efficacy of the homework assignments on the student’s development is indisputable. Besides, what needs to be discussed is what kind of assignments should be given to students, and how they should be evaluated. The aim of this study is to investigate the views of science teachers about homework assignments. The survey method was preferred for this study. A questionnaire was developed by the researchers, and 100 teachers were reached online and via social media. The data obtained from the study were evaluated through quantitative and qualitative analyses. This study shows that the majority of the teachers do not support banning homework, and they consider it as necessary. Teachers mostly assign homework assignments for repetition and reinforcement. Project assignments and research presentation assignments are the most commonly assigned types of homework. Teachers give homework to students which they can do mostly at home spending 0–1 hours together with their friends. According to the teachers, homework provides the most benefits for reinforcement, repetition and learning. In the study, it was found that the majority of the teachers did not use portfolios. According to the teachers participating in the study, the factors that mainly affect student motivation are concentration, reluctance and insufficient knowledge.

In order for students to develop their skills properly in the 21st century and be successful in international examinations such as TIMSS, their understanding of homework must also change to meet the requirements of the age.

Extracorporeal Life Support after Failure of Thrombolysis in Pulmonary Embolism
Authors: Kaese Sven , Lebiedz Pia
Published: March 2020

Introduction: Fulminant pulmonary embolism (PE) may lead to cardiogenic shock or cardiac arrest with high mortality rates (65%) despite treatment with thrombolysis. Patients not responding to this therapy might benefit from extracorporeal life support (ECLS). Only occasional Case Reports of ECLS in PE patients are available. We studied the use of ECLS after thrombolysis in patients suffering from refractory cardiogenic shock due to PE. Material and methods: Patients who were admitted to our university intensive care unit (ICU) with PE, not responding to throm-bolysis, and who received subsequent ECLS treatment were studied. Results: 12 patients with severe PE were included. 6 patients were admitted by emergency medical services, 5 patients were transferred to the ICU from other hospitals and one patient presented at the emergency department by herself. 11 of 12 patients suffered from cardiac arrest and needed cardiopulmonary resuscitation (CPR) before ECLS implantation. Three ECLS were im-planted during CPR and nine ECLS were implanted during emergency conditions in patients with cardiogenic shock. All patients received thrombolysis before implementation of ECLS. Mean duration of ICU treatment was 22.4 ± 23.0 days. Mean duration of ECLS therapy was 5.6 ± 6.5 days. Bleeding complications occurred in four patients. Complications directly related to the ECLS system occurred in two patients (overall complication rate 42%). Overall, 6 of 12 patients (50%) survived. Conclusions: ECLS may be considered as abailout therapy in PE patients not responding to prior definitive treatment such as thrombolysis. ECLS therapy seems to be feasible with an acceptable complication rate even after thrombolysis.

Urban morphology studies developed from the city configuration are important in order to enable consideration on the needs of the place we live, that is, from the city level, as in a reduced analysis, focused on the neighborhood. Thus, morphological analysis serves to subsidize the actions performed by space producers and enables reflection on the impacts generated with each new building or intervention in the urban space. The object of study of the present work is the morphological analysis of a portion of the urban fabric of a small town of Rio Grande do Sul, which is characterized by residences of the population with highest purchasing power in the city, and also by places that present irregular buildings and illegal occupations. The typological study on the urban form has its focus on the analysis of open spaces and how they dialogue with the built spaces. Maps and analyzes identify the occupation of the territory and the different types of open spaces, whether public or private, green or built. The results show how these open spaces are presented and how they are used within the study area. This work presents a methodology for mapping and identifying the quality of free spaces, which, in turn, is very important to support further analysis in other parts of the city and to understand connections and free space systems within the municipality, in order to provide to public agencies a tool that helps in the planning and qualification of the spaces, both the existing ones, as well as future new spaces.

Technology is rooted in the way of life of society and its consumption is increasing, influencing the technological advance, an example of this growing are the mobile phones that according to ANATEL data, in Brazil there are over 228.9 million in use. It is evident the benefits that the technological advance has been providing to society, however it is noteworthy that the electronics have substances toxic to the environment, such a s lead, nickel, cadmium and others that if incorrectly discarded can contaminate the soil even reach the groundwater. thus causing water contamination and compromising the supply of the region, these facts highlight the environmental concern, because it is necessary to adopt measures in front of the env ironmental damages. Given this perspective, the present work aims to analyze the battery life of discarded devices, often the devices are discarded and their battery is also discarded, e ven if it has not completely reached its useful life. To find the current capacity of the battery, the battery current is drained and multiplied by the evaluation time. If the result of the current capacity is less than 80% compared to the nominal battery capacity, it is concluded that it is degraded.

Tobacco cultivation, besides being an important source of income for family farming, also translates into one of the most relevant in the state. Thus, the aim of the present study is to analyze the thermal comfort of rural workers during tobacco harvest, through the temperature and humidity index (UTI) calculated with meteorological data from the years 2017/2018 and 2018/2019, in the Vale region. from Rio Pardo. For this, information was first collected anonymously through a questionnaire answered by 80 rural producers from different municipalities in the region and later, a bioclimatic analysis was performed through the calculation and interpretation of the UTI. The results indicated that the tobacco harvest in the region is held from October to January, in the morning (07:00 to 11:00) and afternoon (14:00 to 19:00) shifts. Thermal comfort analysis showed that in the morning there is no heat stress (UTI 74), unlike the afternoon where UTI indicates thermal heat discomfort (from November to January), which is progressive over the period. (UTI increases from 2:00 pm to 6:00 pm) and may be potentiated by the physical stress accumulated throughout the working day.

A realidade virtual (RV) é uma ferramenta terapêutica que vem sendo amplamente utilizada em diferentes áreas da reabilitação fisioterapêutica, favorecendo o ganho de força muscular, melhora do equilíbrio estático e dinâmico, agilidade e o nível de atividade física. Avaliar os efeitos da RV através do treinamento com Kinect Sports® sobre os níveis de agilidade e equilíbrio em jogadores de badminton. 20 jogadores de badminton participaram do estudo. Os jogadores foram avaliados pelos questionários (questionário sociodemográfico e o questionário de prontidão esportiva com enfoque nas lesões musculoesqueléticas (MIR-Q)). Os testes físicos realizados foram: Star Excursion Balance Test (SEBT) e os testes de agilidade (SEMO e ZIG-ZAG). Após a triagem, os participantes foram distribuídos aleatoriamente em 2 grupos (controle e experimental). Os voluntários do grupo experimental (GE) foram submetidos ao protocolo de RV a partir do treino com Kinect Sports®, enquanto, que o grupo controle (GC) realizaram apenas a rotina de treinamento específica da modalidade esportiva. Observou-se diferenças significativas no GE no teste de equilíbrio (SEBT) em relação aos domínios avaliados: membro inferior direito (MID) (p<0.05; p<0,001 e p<0,0001) e membro inferior esquerdo (MIE) (p<0.05; p<0,001 e p<0,0001) na análise intragrupos. Já nos testes de agilidade (SEMO e ZIG-ZAG) verificou-se reduções significativa no tempo de execução dos protocolos de agilidade (p <0,05) no GE. Com base nos resultados obtidos, pode-se concluir que a RV possibilitou efeitos benéficos sobre agilidade e o equilíbrio em jogadores de badminton em relação aos atletas que não foram submetidos à rotina de treino habitual do badminton.

Objetivo: Avaliar a atividade antibacteriana do anti-inflamatório ácido acetilsalicílico (AAS) frente seis cepas bacterianas padrão de referência American Type Culture Collection (ATCC) e 41 isolados clínicos multidroga resistentes (MDR). Métodos: A atividade antibacteriana do medicamento foi determinada através da concentração inibitória mínima (CIM) obtida frente às cepas bacterianas. Resultados: AAS demonstrou atividade antibacteriana tanto frente a cepas Gram negativas (GN) como Gram positivas (GP), apresentando, frente a maioria das cepas testadas, CIM de 1024 µg/mL e 2048 µg/mL. Frente a um isolado clínico de Acinetobacter baumannii MDR, apresentou CIM de 512 µg/mL. AAS demonstrou atividade antibacteriana frente a microrganismos altamente resistentes. Conclusão: Nossos resultados permitem inferir que o medicamento AAS apresenta potencial atividade antibacteriana frente às cepas MDR testadas, porém estudos complementares devem ser realizados a fim de identificar seu mecanismo de ação na inibição bacteriana. Testes de sinergismos também são aconselhados com o objetivo de avaliar a associação do AAS com antibacterianos já utilizados na clínica, visto que sua atividade pode ser potencializada.

Background: A cancer diagnosis can impose substantial medical financial burden on individuals and may limit their ability to work. However, less is known about worry for nonmedical financial needs and food insecurity among cancer survivors. Methods: The National Health Interview Survey (2013–2017) was used to identify cancer survivors (age 18–39 years, n=771; age 40–64 years, n=4,269; age ≥65 years, n=7,101) and individuals without a cancer history (age 18–39 years, n=53,262; age 40–64 years, n=60,141; age ≥65 years, n=30,261). For both cancer survivors and the noncancer group, adjusted proportions were generated for (1) financial worry (“very/moderately/not worried”) about retirement, standard of living, monthly bills, and housing costs; and (2) food insecurity (“often/sometimes/not true”) regarding whether food would run out, the fact that food bought did not last, and the inability to afford balanced meals. Further adjusted analyses examined intensity measures (“severe/moderate/minor or none”) of financial worry and food insecurity among cancer survivors only. Results: Compared with individuals without a cancer history, cancer survivors aged 18 to 39 years reported consistently higher “very worried” levels regarding retirement (25.5% vs 16.9%; P<.001), standard of living (20.4% vs 12.9%; P<.001), monthly bills (14.9% vs 10.3%; P=.002), and housing costs (13.6% vs 8.9%; P=.001); and higher “often true” levels regarding worry about food running out (7.9% vs 4.6%; P=.004), food not lasting (7.6% vs 3.3%; P=.003), and being unable to afford balanced meals (6.3% vs 3.4%; P=.007). Findings were not as consistent for cancer survivors aged 40 to 64 years. In contrast, results were generally similar for adults aged ≥65 years with/without a cancer history. Among cancer survivors, 57.6% (age 18–39 years; P<.001), 51.9% (age 40–64 years; P<.001), and 23.8% (age ≥65 years; referent) reported severe/moderate financial worry intensity, and 27.0% (age 18–39 years; P<.001), 14.8% (age 40–64 years; P<.001), and 6.3% (age ≥65 years; referent) experienced severe/moderate food insecurity intensity. Lower income and higher comorbidities were generally associated with greater intensities of financial worry and food insecurity in all 3 age groups. Conclusions: Younger cancer survivors experience greater financial worry and food insecurity. In addition to coping with medical costs, cancer survivors with low income and multiple comorbidities struggle to pay for daily living needs, such as food, housing, and monthly bills.

Background: Pathologic complete response (pCR) after neoadjuvant chemotherapy (NAC) for triple-negative breast cancer (TNBC) predicts decreased distant metastasis. However, most patients do not experience pCR, and other risk factors for distant metastasis after NAC are poorly characterized. This study investigated factors predictive of distant metastasis in TNBC without pCR after NAC. Methods: Women with TNBC treated with NAC, surgery, and radiation therapy in 2000 through 2013 were reviewed. Freedom from distant metastasis (FFDM) was compared between patients with and without pCR using the Kaplan-Meier method. In patients without pCR, univariate and multivariable Cox analyses were used to determine factors predictive of distant metastasis. Results: We identified 153 patients with median follow-up of 4.0 years (range, 0.5–14.0 years). After NAC, 108 had residual disease (pCR, 29%). Five-year FFDM was 98% and 55% in patients with and without pCR, respectively (P<.001). Factors independently predicting FFDM in patients without pCR were pathologic nodal positivity (hazard ratio, 3.08; 95% CI, 1.54–6.14; P=.001) and lymphovascular space invasion (hazard ratio, 1.91; 95% CI, 1.07–3.43; P=.030). Patients with a greater number of factors had worse FFDM; 5-year FFDM was 76.5% for patients with no factors (n=38) versus 54.9% and 27.5% for patients with 1 (n=44) and 2 factors (n=26), respectively (P<.001). Conclusions: Lack of pCR after NAC resulted in worse overall survival and FFDM, despite trimodality therapy. In patients with residual disease after NAC, pathologic lymph node positivity and lymphovascular space invasion predicted worse FFDM.

O estudo avaliou a possibilidade da utilização de escória de aciaria em conjunto com solo, como um material alternativo para uso em camadas de pavimentação rodoviária. O estudo foi baseado em resultados e pesquisas obtidos no laboratório de Pavimentação do Instituto Tocantinense Presidente Antônio Carlos – Porto Nacional (ITPAC-PORTO) seguindo todos os procedimentos adotados pelas normas ABNT. Para a análise realizou-se ensaios de granulometria, limites liquidez, limites de plasticidade, compactação, expansão e CBR. Foram realizados ensaios nas amostras de solo puro, escória pura e misturas de 15% escória com 85% solo e 30% escória e 70% solo. O solo utilizado na pesquisa tem predominância argilosa e pelos métodos de classificação SUCS e HRB foram identificados como ML ou AL e A-4 respectivamente. Na caracterização granulométrica da escória de aciaria notou-se que a mesma possuía seu diâmetro de acordo com a MME compatível com o diâmetro da brita 1. À medida que se aumentou a quantidade de escória de aciaria da empresa SINOBRAZ sua massa especifica aparente seca também aumentava, o contrario acontecia com o teor de umidade da mistura, que quanto mais escória menor o valor de teor de umidade. Concluímos a partir dos ensaios realizados que a escória de aciaria da empresa SINOBRAZ com a energia de compactação normal e solo com predominância argilosa não teve um aumento significativo em seu Índice de Suporte Califórnia, sendo possível a utilização das misturas de 15% e 30% de escória apenas em camadas de sub-base na pavimentação rodoviária.

Aim. Determine the effect of mitochondrial DNA loss on the formation of complex yeast colonies of Saccharomyces cerevisiae. Methods. Development of giant colonies of the parent strain SK1 (rho+) and the "petit" strain SK1p, which lost mtDNA (rho0 mutation), was observed for 40 days,. To find out zones of cell death in colonies, both strains were cultured on solid YPD media containing dyes that accumulate in dead cells. The survival of the cells within colony was estimated by the ability to create microcolonies.  Results. The loss of mitochondrial DNA in SK1p cells led to a decrease in colony area and to simplification of colony morphology on the YPD medium. When SK1p colonies were cultivated on media with addition of dyes, bright spot was formed in the center due to the dyes accumulation  in dead cells. At the same time, parent strain developed a uniform insignificant coloration.  Conclusions. rho0 mutation in SK1p yeast strain Saccharomyces cerevisiae led to a significant simplification of complex colony structure that formed on the nutrient medium YPD. The mitochondrial DNA loss in strain SK1p results in an accelerated cell death in the center of colony on YPD.Keywords: Saccharomyces cerevisiae, rho0, colonies, cell survival.
