The sorption distribution coefficient of lead and copper on the selected soil samples from Selangor

The sorption of heavy metals (i.e. Pb and Cu) in soils from Selangor was investigated using batch equilibrium test (BET). The test was conducted in two systems, i.e. single and mix solutions. The sorption isotherms from BET were well described by the Langmuir equation which then used to calculate the sorption parameters, i.e. distribution coefficient (Kd) and maximum adsorption capacity (Am). The Langmuir sorption equation was chosen according to the experimental data that are fitted to the equation (i.e. based on their linear regression values, r2). The study has revealed that different soils have different sorption capacity for different heavy metals. The Kd values are proportional to the sorption capacity of soils. Soil with high sorption capacity possesses higher Kd value. The sorption of Pb and Cu in single solution is higher than in mix solution, due to competition for sorption sites among heavy metals in mix solution. The Kd values for Pb in single solution ranging from 36.18 – 334.48 L/g and for Cu is 9.29-66.19 L/g. In mix solution, the Kd values for Pb and Cu are smaller ranging from 23.13-31.79L/g and 3.95-18.53 L/g respectively.

Produção e aspectos econômicos de milho consorciado com Crotalária juncea L. em diferentes intervalos de semeadura, sob manejo orgânico

A busca por sistemas produtivos mais sustentaveis e um desafio necessario. Avaliaram-se formas de manejo do consorcio entre milho e Crotalaria juncea L. , que possibilitem otimizar a producao “in situ” de massa vegetal, sem comprometer o potencial produtivo do cereal. Realizaram-se experimentos em epocas distintas: primavera-verao (experimento 1) e outono-inverno (experimento 2), em Seropedica -RJ, no periodo de 11/2010 a 09/2011. Os tratamentos para o experimento 1 foram: C. juncea, semeada: sete dias antes, simultaneamente com, aos 14 e aos 28 dias apos a cultura do milho, respectivamente, para T1, T2, T3 e T4. Alem desses, T5-milho em monocultivo e T6-milho em monocultivo + N. Os tratamentos para o experimento 2 foram: C. juncea semeada: sete dias antes, simultaneamente com, aos sete e aos 14 dias apos a cultura do milho, respectivamente para TA, TB, TC e TD. Alem desses, TE-milho em monocultivo e TF-milho em monocultivo + N. Para T1, T2, TA e TB a C. juncea foi rocada aproximadamente 30 dias apos a emergencia e sua palhada utilizada como fonte de N para o milho; ja para T3, T4, T6, TC, TD e TF foi utilizada a torta de mamona como fonte de N. Na primavera-verao, em T2, a producao de graos do cereal nao diferiu da producao do monocultivo com adubacao nitrogenada, com reflexo positivo no balanco economico. No outono-inverno, a presenca do adubo verde semeado 14 dias apos o milho resultou em beneficios ao sistema. A C. juncea, quando cultivada na primavera-verao, apresentou potencial para fornecer N ao milho como alternativa a adubacao nitrogenada de cobertura.
Treści i sposoby prowadzenia edukacji o miejscowości, w której znajduje się szkoła w opinii nauczycieli geografii województwa śląskiego

Przedmiotem rozważań jest samoocena nauczycieli geografii w zakresie przygotowania oraz realizacji edukacji regionalnej w szkole. Pytanie badawcze (problem badawczy) brzmi: Jak nauczyciele geografii oceniają swoje przygotowanie do prowadzenia zajęć na temat miejscowości, w której pracują, oraz realizację tychże zajęć? Narzędziem służącym pozyskaniu odpowiedzi na postawione pytania był kwestionariusz ankiety. Względy organizacyjne (możliwość dotarcia do nauczycieli jak największej liczby szkół poprzez tzw. panel dyrektorski kuratorium oświaty) zadecydowały o przebadaniu wybranej grupy respondentów – nauczycieli geografii województwa śląskiego. Zastosowano elektroniczną formę zbierania danych z wykorzystaniem kwestionariusza google. Analiza otrzymanych wyników pozwala zauważyć, że nauczyciele wysoko ocenili swoją wiedzę o miejscowości, w której pracują, a jej źródłem są głównie własne obserwacje i internet (m.in. strona internetowa gminy). Zdecydowana większość respondentów dostrzegła wiodącą rolę geografii jako przedmiotu służącego realizacji celów edukacji regionalnej. Konieczność obecności w szkole zajęć dotyczących tej tematyki, w opinii badanych nauczycieli, jest powszechnie akceptowana. Niepokojące jest stanowisko geografów na temat doboru treści edukacji regionalnej: stosunkowo niskiej akceptacji obecności zagadnień społecznych (w tym demograficznych) gospodarczych, oraz preferowanie treści kulturowych i historycznych jako najbardziej reprezentatywnych dla edukacji o „swojej” miejscowości.
Gender Differences in Healthcare-Seeking Behaviors in China’s Ageing Population: An Empirical Study of Shanghai

Background: Given the growing healthcare demands of the elderly, an improved understanding of the factors influencing their healthcare-seeking behaviors is necessary to enhance the effectiveness of the current healthcare system. This study empirically investigates the factors influencing the elderly population’s healthcare-seeking behaviors in Shanghai, China, from a gender differences perspective.Methods: We combine both quantitative and qualitative analyses by constructing a binary logistic regression model and identifying the relevant influential factors based on the following types of dimensions: individual, family, and cultural.Results: The results indicate that gender differences exist in the elderly population with common diseases but not in those with severe diseases, and that the female elderly are more likely to choose non-tertiary hospitals than males. In addition, age, marital status, employment status, income, health conditions, medical insurance, family support, and social capital are found to be critical influencing factors.Conclusions: The findings provide a better understanding of the elderly population’s healthcare demands and can be used to promote healthcare equality.
Protecting Decision Boundary of Machine Learning Model With Differentially Private Perturbation

Machine learning service API allows model owners to monetize proprietary models by offering prediction services to third-party users. However, existing literature shows that model parameters are vulnerable to extraction attacks which accumulate prediction queries and their responses to train a replica model. As countermeasures, researchers have proposed to reduce the rich API output, such as hiding the precise confidence. Nonetheless, even with response being only one bit, an adversary can still exploit fine-tuned queries with differential property to infer the decision boundary of the underlying model. In this article, we propose boundary differential privacy (BDP) against such attacks by obfuscating the prediction responses with noises. BDP guarantees an adversary cannot learn the decision boundary of any two classes by a predefined precision no matter how many queries are issued to the prediction API. We first design a perturbation algorithm called boundary randomized response for a binary model. Then we prove it satisfies <inline-formula><tex-math notation="LaTeX">$\epsilon$</tex-math><alternatives><mml:math><mml:mi>ε</mml:mi></mml:math><inline-graphic xlink:href="zheng-ieq1-3043382.gif"/></alternatives></inline-formula>-BDP, followed by a generalization of this algorithm to a multiclass model. Finally, we generalize a hard boundary to soft boundary and design an adaptive perturbation algorithm that can still work in the latter case. The effectiveness and high utility of our solution are verified by extensive experiments on both linear and non-linear models.

Detection And Molecular Characterization of Theileria Ovis in Sheep And Goats with Clinical The Ileriosis in Kurdistan, Iraq

This study was carried out to detect Theileria infection in sheep and goats in Kurdistan region, Iraq from June 2019 to April 2020. Molecular method was used to identify Theileria species. Sixty- seven blood samples were taken from 45 sheep and 22 goats based on clinical signs of theileriosis during tick activating season. The 67 samples were PCR edm and as a result, 20 species-specific PCR were positives (26.67% (12/20) were Theileria ovis in sheep and 36.36% (8/20) were from goats). The results of the gene analysis in the current study were registered in NCBI under four accession numbers (MN889986, MN889987, MN889988 and MN889989), which shows that sheep and goats can be infected with Theileria ovis. This is the first report of Theileria species in goats with clinical theileriosis in Kurdistan, so the gene flow and disease transmission between sheep and goats is most expected. PCR is a useful diagnostic tool to detect ovine theileriosis with a single test and suggested that T. ovis is the dominant piroplasmid agent in Erbil. In addition, it revealed that sheep is very susceptible to theileriosis than goats
Using experimental methods and CSD data for investigating the products of the reaction between 2-((2-aminoethyl)amino)ethanol with CdI2 and CdI2/HgI2-mixtures

Abstract The binding modes of 2-((2-aminoethyl)amino)ethanol-based ligands were explored using the Cambridge Structural Database (CSD). To extend this field, a new cadmium complex containing 2-((2-aminoethyl)amino)ethanol (AEAE), [Cd(AEAE)2][Cd(AEAE)2]′[CdI4]2 (1), was prepared and characterized by spectroscopic methods and single-crystal X-ray diffraction. The reaction of AEAE with a 1:1 mixture of CdI2 and HgI2 was also investigated. The complex, [Cd(AEAE)2][I2Hg(μ-I2)2HgI2] (2), was synthesized and characterized. Compounds 1 and 2 represent the first tridentate binding modes of an AEAE type ligand with Cd2+. Geometrical investigation for complexes containing Cd(Namine2Oalcohol)2, CdIn, and HgIn environment were carried out using the CSD software. Also different possible diastereomers which can be formed in coordination of a pair of tridentate AEAE ligands in octahedral geometry were studied and discussed.
Roma street-workers in Uppsala: racialised poverty and super precarious housing conditions in Romania and Sweden

Abstract Using a combination of a political economy approach for the analysis of housing with a postcolonial approach to mobility patterns of the racialised and impoverished Roma in Europe, we reflect on the relationship between racialisation and the precarious living and housing conditions of the Eastern European Roma who move from the poorer to the richer countries of the European Union. Through a qualitative and multi-sited approach to housing, we reveal the situation of permanent displacement for racialised Romanian Roma groups in both Sweden and Romania. We have followed Roma street-workers who come to Sweden for earning income in order to improve their homes in Romania, but once there, they are exposed to homelessness, harsh weather conditions, racism and discrimination. We found that the super precarious conditions of housing in Romania push the migrant Roma into even worse housing and living conditions in the destination country, completing a vicious circle of forced nomadism in which the lack of right to decent housing and permanent risk of displacement are central aspects. This article merges the interests of urban and housing researchers with those from the postcolonial tradition.
Robust Regression Discontinuity Estimates of the Causal Effect of the TripAdvisor’s Bubble Rating on Hotel Popularity

In this paper we use detailed data on 4,599 hotels located in Rome collected from TripAdvisor, the world's largest travel platform, to examine the causal effects of bubble ratings (detailed to half-bubbles) on hotel popularity measured with the number of people viewing the hotel’s page. By using a regression discontinuity design, we find that bubble presentation of ratings does not create any significant jumps at cutoffs. This result is different from those obtained in previous studies of similarly designed rating systems from other industries. Another finding is that web users tend to shortlist hotels with the bubble rating of at least 3. Despite that, there is no strong evidence of review manipulation around the 2.75 cutoff to make a transition from the 2.5-bubble rating to the 3-bubble rating. Potential uses of the number of views as a proxy of demand in hospitality and tourism research are outlined.
Forecasting Electricity Consumption Using the Second-Order Fuzzy Time Series

There is a great development of Universiti Tun Hussein Onn Malaysia (UTHM) infrastructure since its formation in 1993. The development will be accompanied by the increasing demand for electricity. Hence, there is a need to forecast UTHM electricity consumption accurately so that UTHM can plan for future energy demand and utility saving decisions. Previous studies on UTHM electricity consumption prediction have been carried out using time series models, multiple linear regression and first-order fuzzy time series (FTS). The first-order FTS yield the best accuracy among these three methods. Previous forecasting problem showed higher order FTS can yield better accuracy. Therefore, in this study, the second-order FTS with trapezoidal membership function was implemented on the UTHM monthly electricity consumption from January 2009 to December 2018 to forecast January to December 2019 monthly electricity consumption. The procedure of the FTS and trapezoidal membership function was described together with January data. The second-order FTS forecast UTHM electricity consumption better than the first-order FTS.
Communities of Mucorales (phylum Mucoromycota) in different ecosystems of the Atlantic Forest

As primary decomposers of organic matter, mucoralean fungi have an important ecological role in edaphic systems in the Atlantic Forest. However, there is a knowledge gap regarding how communities of Mucorales are structured in soils of Atlantic Forest areas, and whether these communities are influenced by edaphic attributes in this domain. Thus, the current study aimed to understand the influence of edaphic attributes linked to species richness, abundance and composition of Mucorales in dense ombrophilous forest, ‘ tabuleiro ’ forest, sandbank and mangrove ecosystems located in Pernambuco, Brazil. Altogether, twenty-three taxa, including seven new records, were reported from soil samples from the ecosystems. Species composition was similar among the ecosystems, except for mangrove, while species richness and diversity of Mucorales were highest in dense ombrophilous forest and ‘ tabuleiro ’. Together the soil variables were responsible for 35.5 % of the variation in species composition, with pH being responsible for 53.32 % and 47.24 % of the variation in richness and abundance of these communities, respectively. These data indicate that pH is the most important attribute in delimiting the structure of mucoralean communities in the study areas, with influence on the composition, richness, and abundance of these fungi.
Ex Vivo and In Vivo Anti-inflammatory Evaluations of Modulated Flavanones Solutions

Interest has developed in natural molecules due to their clinically proven effects on skin diseases. Flavanones display several biological activities, and recently have been the focus of studies due to their anti-inflammatory effect. To improve their pharmacological profile, four flavanones (A, B, C, and D) were synthesized by structural modification of one natural flavanone 1 (semi-systematic name: (2S)-5,7-dihydroxy-6-prenylflavanone) extracted from Eysenhardtia platycarpa. The hydroalcoholic flavanone solutions (FS) were assayed to investigate their anti-inflammatory effect on two in vivo cutaneous inflammation models. Materials and methods: the topical anti-inflammatory effects of FS were evaluated against models of 12-O-tetradecanoylphorbol acetate (TPA)-induced mouse ear edema and arachidonic acid (AA) in rat ear edema. Results: The vinylogous cyclized derivative (flavanone D) caused edema inhibition in the TPA-induced models with an inhibition of 96.27 ± 1.93%; equally effective and potent in inhibiting the mouse ear edema as indomethacin had been. In addition, the AA-induced increase in ear thickness was reduced the most by the topical application of modulated ether (flavanone B). Conclusions: The in vivo and histology results suggest that flavanones B and D are effective as topical anti-inflammatory agents in inflammatory processes. Thus, this new compound represents a promising agent for the management of skin diseases with an inflammatory component.
Cross-school collaboration in the Finnish archipelago through Virtual Learning Environments

In this feature, I present implications from a cross-school project in the Finnish archipelago (2015–17). Three primary schools and five teachers collaborated with the researcher to extend their classrooms through a Virtual Learning Environment (Fronter, Blackboard Collaborate). Data were analysed with the theory of practice architectures . The schools were part of complex arrangements on several levels that had implications for the success of the remote teaching initiative: classroom level (e.g. digital competence), school level (e.g. joint teacher positions, faculty support) and regional level (e.g. school transport, relevant digital infrastructure).
Genetic Analysis of Chocolate Spot and Rust Disease Resistance and Some Yield Related traits in Three Faba Bean Crosses

Breeding for high yield potential along with resistance to chocolate spot and rust diseases are the main target of most faba bean breeding programs. The five populations (P1, P2, F1, F2 and F3) of three faba bean crosses (Triple White x Ohishima Zairai), (Triple White x Giza 40) and (Triple White x Foul Sbai labiade) were evaluated during 2019 /2020 winter season at Sakha Agricultural Research Station, to study the type of gene action for foliar diseases resistance and some yield related traits. Significant differences were found among generations, i.e. P1, P2, F1, F2 and F3 for the majority of studied traits of all crosses. Significant and highly significant desirable percentages of heterosis relative to mid and better parent with favorable values for inbreeding depression for most traits. Additive gene effects were positive and highly significant for chocolate spot disease reaction, rust disease reaction. However, the dominant gene effects seem to be controlling the inheritance of yield and yield component traits. Narrow-sense heritability ranged from medium to high in most cases due to the opposite directions of dominance and dominance x dominance effects. Genetic advance from selection ranged from 7.66% for flowering date to 45.65% for No. of pods plant-1in cross 3. Finally; it could be concluded that cross 2 and cross 3 were the best for flowering date, seed yield/plant and 100-seed weight, while cross 3 was the best in resistance to chocolate spot and rust diseases. Therefore, selection in the advanced generations of both crosses could be effective.
Company Performance: Are Environmental, Social, and Governance Factors Important?

Building on the resource-based view of entrepreneurship, we examine the association between environmental, social, and governance (ESG) factors and company performance, measured by return on assets, return on equity, and return on invested capital. We use regression models on a dataset of 60 observations of Russian companies including RAEX agency ESG ratings from 2018 to 2019. The results show that, in line with expectations, companies that comply with ESG principles demonstrate significantly better financial performance than other companies. This result holds true irrespective of the performance indicator used. Moreover, the governance factor is strongly related to company performance, providing implications for companies' policymakers in terms of the utility of adopting ESG information. The study provides insights into the resource-based view of entrepreneurship, demonstrating that ESG factors, and mainly the governance factor, create a competitive advantage for companies and allow superior performance.
Stroke in young adults – a challenge for etiology, treatment and rehabilitation

Abstract Strokes occur rarely in individuals under the age of 45 and are even more uncommon under the age of 30, the etiology of this pathology in young adults being generally related to unknown or unusual causes. We present the cases of three young adults that suffered strokes with three different unusual etiologies. The three men were 30, 36 and 43 years old, with no pathological antecedents, with neurological symptoms characteristic for stroke. Because the differential diagnostics are sometimes tricky, in all three cases imagery was very helpful. It is necessary to emphasize that in these cases one of the most important things to know is the etiology. It is very important to treat the effect too; this is the reason why we never miss an opportunity to use alteplase when all conditions are met. Common rehabilitation regimes for young adults, who have suffered a stroke, include a combination of physiotherapy, occupational therapy, speech-language therapy, and pharmacological therapy. Strategies to improve motor recovery in young patients include constraint-induced movement therapy, robot-aided rehabilitation, virtual reality training, functional electrical stimulation, increased exercise intensity, and acupuncture.
