Authors: Kalu Amare Worku , Telele Nigus Fikrie , Aralaguppe Shambhu G , Gebre-Selassie Solomon , Fekade Daniel , Marrone Gaetano , Sonnerborg Anders
Published: May 2018

Objectives:

Genotypic Tropism Testing (GTT) tools are generally developed based on HIV-1 subtype B (HIV-1B) and used for HIV-1C as well but with a large discordance of prediction between different methods. We used an established phenotypic assay for comparison with GTT methods and for the determination of in vitro maraviroc sensitivity of pure R5-tropic and dual-tropic HIV-1C.

Methods:

Plasma was obtained from 58 HIV-1C infected Ethiopians. Envgp120 was cloned into a luciferase tagged NL4-3 plasmid. Phenotypic tropism was determined by in house method and the V3 sequences were analysed by five GTT methods. In vitro maraviroc sensitivity of R5-tropic and dual-tropic isolates were compared in the TZMbl cell-line.

Results:

The phenotypes were classified as R5 in 92.4% and dual tropic (R5X4) in 7.6% of 79 clones. The concordance between phenotype and genotype ranged from 64.7% to 84.3% depending on the GTT method. Only 46.9% of the R5 phenotypes were predicted as R5 by all GTT tools while R5X4 phenotypes were predicted as X4 by four methods, but not by Raymond’s method. All six tested phenotypic R5 clones, as well as five of six of dual tropic clones, showed a dose response to maraviroc.

Conclusion:

There is a high discordance between GTT methods, which underestimates the presence of R5 and overestimates X4 strains compared to a phenotypic assay. Currently available GTT algorithms should be further improved for tropism prediction in HIV-1C. Maraviroc has an in vitro activity against most HIV-1C viruses and could be considered as an alternative regimen in individuals infected with CCR5-tropic HIV-1C viruses.

Authors: Aftab Raja Ahsan , Khan Amer Hayat , Sulaiman Syed Azhar Syed , Ali Irfhan
Published: May 2018

Aims and objective:

The aim of the current study is to evaluate adherence clinical practice guideline of asthma, to assess treatment outcomes of guideline adhering to pharmacotherapy and to calculate the cost of asthma treatment.

Methods:

A prospective record viewing study was conducted at the respiratory clinic of Hospital Pulau Pinang, Penang, Malaysia from December 2012 to June 2013. A total of 180 prescriptions of patients from 6 doctors (30 prescriptions by each doctor) were evaluated against global initiative of asthma (GINA) guidelines. Treatment outcomes of asthma patients were evaluated based on lung function values. Direct assessment of cost was compared between the guidelines adhered and non-adhered scripts.

Results:

Of the total 180 asthmatic patients, 143 (78.9%) received guideline-adhered pharmacotherapy. A total of 158 (87.7%) patients reported successful treatment outcome, out of which, 124 (78.4%) patients received guideline-adhered pharmacotherapy. A statistical significant difference (p < 0.001) was observed among lung function values after patients’ first and second visit. An analysis indicated that patients aged > 46 years were found to have a significant association with treatment outcomes (OR=3.77, p=0.03). While comparing the cost of asthma treatment outcome, it was observed that the average cost of successfully treated patients who received guideline-adhered pharmacotherapy was RM 70.00 per patient (1US$ = RM 3.20) while patients reporting unsuccessful treatment outcome was RM 75.47 per patient.

Conclusion:

A majority of asthma patients received guideline-adhered pharmacotherapy.

Authors: Sevilla-Llewellyn-Jones Julia , Santesteban-Echarri Olga , Pryor Ingrid , McGorry Patrick , Alvarez-Jimenez Mario
Published: May 2018

Background

Web-based mindfulness interventions are increasingly delivered through the internet to treat mental health conditions.

Objective

The objective of this study was to determine the effectiveness of web-based mindfulness interventions in clinical mental health populations. Secondary aims were to explore the impact of study variables on the effectiveness of web-based mindfulness interventions.

Methods

We performed a systematic review and meta-analysis of studies investigating the effects of web-based mindfulness interventions on clinical populations.

Results

The search strategy yielded 12 eligible studies. Web-based mindfulness interventions were effective in reducing depression in the total clinical sample (n=656 g=−0.609, P=.004) and in the anxiety disorder subgroup (n=313, g=−0.651, P<.001), but not in the depression disorder subgroup (n=251, P=.18). Similarly, web-based mindfulness interventions significantly reduced anxiety in the total clinical sample (n=756, g=−0.433, P=.004) and the anxiety disorder subgroup (n=413, g=−0.719, P<.001), but not in the depression disorder group (n=251, g=−0.213, P=.28). Finally, web-based mindfulness interventions improved quality of life and functioning in the total sample (n=591, g=0.362, P=.02) in the anxiety disorder subgroup (n=370, g=0.550, P=.02) and mindfulness skills in the total clinical sample (n=251, g=0.724, P<.001).

Conclusions

Results support the effectiveness of web-based mindfulness interventions in reducing depression and anxiety and in enhancing quality of life and mindfulness skills, particularly in those with clinical anxiety. Results should be interpreted with caution given the high heterogeneity of web-based mindfulness interventions and the low number of studies included.

Detail Engineering Design of Compact Neutron Generator to Support BNCT Facility in Indonesia
Authors: Widarto Widarto
Published: May 2018

Boron Neutron Capture Therapy (BNCT) is a method of cancer therapy based on neutron radiation which has advantages over the other cancer therapy methods. It uses a stable isotope of 10B which will be an excited isotope of 11B when irradiated by thermal neutron. It immediately (in 10-12 s) breaks into α particle and a lithium recoil nucleus. The two secondary particles play important roles in killing cancer cells. They have a short range in tissue (5 µm and 9 µm respectively) which is less than the average dimension of a cell. This leads to the damage of cancer cell only but the normal cells remain safe. Thermal and epithermal neutrons play important roles in BNCT. From the beginning the neutron sources for BNCT are nuclear reactors which produce high intensity of thermal neutrons (En <0.5 eV), epithermal neutrons (0.5 eV< En < 10 keV) and fast neutrons (En > 10 keV). However, nuclear reactors are very expensive and too large to be used in hospitals. In addition, the operation of nuclear reactors is under restricted protocols related to safety and physical protection. A compact neutron generator is a good choice of neutron source for BNCT. The advantages of compact neutron generator are that the size is small and that the neutron yield is more than 109 ns-1 which satisfies the requirement recommended by IAEA. Additionally, the neutron energy is not so high that it requires a complicated neutron collimator, the operation is easy, and the public acceptance is higher than with nuclear reactors. Based on the requirements of epithermal neutron beam for BNCT facility, the detailed engineering design of compact neutron generator has been made.
On precipitation of struvite (MgNH4PO4.6H2O)
Authors: Muryanto Stefanus
Published: May 2018

Excessive input of N and P into water bodies causes eutrophication which leads to deterioration of aquatic evironments and has adverse effects naturally and economically. It is therefore urgent to remove N and P from wastewater prior to disposal into inland and coastal waters. Among the various removal methods, controlled struvite precipitation is preferred. Struvite (MgNH4PO4.6H2O) precipitates uncontrollably under the specific conditions producing a scale deposit causing persistent problems in industries and wastewater treatment plants. The scale deposit clogs the piping system and impair plant equipment. On the other hand, thanks to its composition and properties, struvite is a potential fertilizer. In medical field, struvite is a common component of kidney stones. A number of process parameters govern the struvite precipitation. This paper briefly presents these parameters: pH, molar ratios, temperature, mixing, and presence of foreign ions. pH level is considered as the most important variable affecting the precipitation of struvite and the pH level: 9.5 to 10.5 is seen as the optimum. For an effective precipitation the molar ratios of the struvite components, i.e. Mg:N:P should be at least unity. With regard to struvite solubility, the effect of temperature, in the range of 21oC to 49oC, is conflicting, which is probably due to different experimental conditions. Whilst agitation is not regarded as a decisive parameter, the influence of foreign ions, notably divalent metal ions, on struvite morphology and change of crystal phases is significant.
Evaluation of performance of POAMA forecast system in predicting monthly precipitation over Indonesia
Authors: Suaydhi Suaydhi
Published: May 2018

Hindcast produced by a model used in a numerical model-based seasonal prediction system is an essential part in the operational seasonal prediction system. This paper is aimed at evaluating the performance of POAMA model from the climatological aspect. The data used in this research are obtained from three variants of POAMA m24 model. The results show that the annual cycle of climatological rainfall averaged over Indonesia is well simulated by POAMA m24, although there is a dry bias in the rainy season and a wet bias in the dry season. From those three variants, m24b model has a relatively low variation of bias against lead-time compared with the m24a and m24c models due to the implementation of flux correction scheme in m24b model. However, the performance of POAMA m24 model with a resolution of T24 is inferior to CFSv2 with a resolution of T126 in simulating the spatial pattern of rainfall over Indonesia. Beside model resolution, convection scheme used in a model also has significant influence. This can be seen from the resemblance between the spatial pattern of total rainfall and that of convective rainfall. Thus, the horizontal resolution of a model and a suitable convection scheme for Indonesian region are the two factors that must form important consideration in the development of Indonesian seasonal prediction system.
Impact of social identity on second language learning anxiety: The Pakistani perspective
Authors: ZAHİD Zohaib , GHANİ Mamuna
Published: May 2018

The language learners
in Pakistan are required to get adequate knowledge of English language in order
to strive for a better future. It has been investigated that in few parts of
the world the learners are inclined towards their social identity, culture,
tradition and values which sometimes hinder them to speak foreign language. It
has been observed by the linguists that social identity is a cause of anxiety
in second language learners in different parts of the world. Due to inclination
towards their own language, the students become reluctant to use another
language which ultimately makes them anxious and less proficient learners.  This study has been conducted to investigate
whether social identity is also a cause of anxiety in second language learning
in Pakistan. The researchers have focused the main and core issues of identity
which are stuck in the minds of the language learners when they learn English language.

Computing Bayes factors to measure evidence from experiments: An extension of the BIC approximation
Authors: Faulkenberry Thomas J.
Published: May 2018

Bayesian inference affords scientists powerful tools for testing hypotheses. One of these tools is the Bayes factor, which indexes the extent to which support for one hypothesis over another is updated after seeing the data. Part of the hesitance to adopt this approach may stem from an unfamiliarity with the computational tools necessary for computing Bayes factors. Previous work has shown that closed-form approximations of Bayes factors are relatively easy to obtain for between-groups methods, such as an analysis of variance or t-test. In this paper, I extend this approximation to develop a formula for the Bayes factor that directly uses information that is typically reported for ANOVAs (e.g., the F ratio and degrees of freedom). After giving two examples of its use, I report the results of simulations which show that even with minimal input, this approximate Bayes factor produces similar results to existing software solutions.
Exploring Education and Education Reforms from the Complex Systems Point of View
Authors: Joksimović Ljubinka , Manić Slavica
Published: May 2018

The main motivation for this paper is that a negligible number of reforms in education systems, initiated all over the world, proved to be successful in terms of bringing desired results in promoting educational practice and its final goal - the promotion of students’ learning and knowledge. Regarding the education system and its reform a change of paradigm has recently happened. In some cases, changes were made gradually, whereas in other cases it was completely abandonment of treating them as complicated systems with simple interventions and solutions toward the recognition and respect of their true complex nature. So, this reviewed paper explores new insights and tools derived from the theory of complexity. They can help to better understand and navigate the education system and its reform. Becoming familiarised with methodological implications of viewing the education system and its reform as complex system is recommendation for different stakeholders included in education system, such as teachers, students, researchers, administrators and policy makers. Advance awareness of both urgency and opportunities of analysing and respecting the education system as a complex system would contribute to better understanding the essence of dynamic wholeness of education and, for sure, would provide desired results of educational reform. For all of us that means more successful coping with the world characterised by a growing number of complex systems with growing intensity.
Conditions and Possibilities of Geothermal Energy Utilization to Enhance Economic-Touristic Development of Jošanička Banja
Authors: Šušić Vukašin , Šaćirović Selim , Marić Anđelina
Published: May 2018

According to the temperature, thermomineral water can be used for various balneological treatmens, as well as for agriculture, communal economy, electro economy, etc. This paper analyses homeohtermal (36°C) and hiperthermal (78°C) waters of the spa Jošanička banja which, together with that of Sijarinska (70°C) and Vranjska banja (90-110°C) are some of the hottest waters in the Republic of Serbia. Besides the temperature for balneo and wellness therapies, also very important are mineral properties which show that the water of the spa in question is characterised by the law level of mineralisation with slightly increased concentration of fluorine, sulfate, metabolic acid, silicon dioxide and similar compounds, which makes them suitable for the treatment of degenerative and inflammatory rheumatism, muscle disease, lumbago, sciatica etc. Based on the analysis of the water temperature and yield of dozens of springs with hiperthermal water, thermal capacity of spa water is determined as well as the possibility of using it in the electro economy, communal economy and agriculture. In conclusion, the use of thermomineral water during balneological treatmens can have different, more practical and more economic model. Practice shows that partial use of healing thermomineral water represents a significant loss in energy on the one hand, where, on the other hand, direct discharge of hot water can negatively affect individual components of the enviroment.
Do Serbian Companies Provide Relevant Disclosures About Goodwill?
Authors: Spasić Dejan
Published: May 2018

IFRS 3 have been adopted to increase the relevance of information on business combinations. Consequently, it is expected that information on goodwill will contribute to that goal. By analysing the sample of the most important companies in the Republic of Serbia, this paper identifies several key areas of disclosure regarding recognition, initial recognition, and subsequent measurement of goodwill. All companies listed on the Belgrade Stock Exchange (BSE) which prepare consolidated financial statements are taken for the sample. In addition, the paper includes selected non-listed companies (that are most important for the Serbian economy according to the criteria of revenue, number of employees, and the share in the total GDP) in the sample. The final sample consists of 156 consolidated financial statements of 43 groups in the analysed four-year period (2013-2016). Descriptive statistic is used. The author found a low level of disclosure, which is further accompanied by misapplication of IFRS.

The congenital cardiac diseases predominately affect the children, as well as the young adults, and they are the consequence of an abnormal embryological development.

Atrial septal defect (DSA) is a congenital heart malformation, which can close in the first year of life, being shown by the presence of a communication between the left atrium and right atrium with the left-to-right shunt, and it subsequently produces some complications.

We report the case of a 31 years-old-female without previous medical history, who was diagnosed with atrial septal defect.
Forecasting using a Nonlinear DSGE Model
Authors: Ivashchenko Sergey , Gupta Rangan
Published: May 2018

A medium-scale nonlinear dynamic stochastic general equilibrium (DSGE) model was estimated (54 variables, 29 state variables, 7 observed variables). The model includes an observed variable for stock market returns. The root-mean square error (RMSE) of the in-sample and out-of-sample forecasts was calculated. The nonlinear DSGE model with measurement errors outperforms AR (1), VAR (1) and the linearised DSGE in terms of the quality of the out-of-sample forecasts. The nonlinear DSGE model without measurement errors is of a quality equal to that of the linearised DSGE model.
Process of Deindustrialization in Montenegro
Authors: Tomljanović Marko , Grubišić Zoran , Huđek Ivona
Published: May 2018

Deindustrialization is a dynamic process that began to attract the attention of economic theorists in the 60s of the 20th century, which is characterized by a reduction in the share of the industrial sector in GDP and employment. A descriptive analysis of the deindustrialization process in Montenegro was carried out. It was established that throughout the observed period, the process of deindustrialization in Montenegro has characteristics present in developed countries. However, a deeper analysis and taking into account the key indicators showed that deindustrialization in Montenegro did not just arise as a sole consequence of positive economic trends. In addition, the entire process took place under the influence of various non-economic indicators. Moreover, the global economic crisis had a significant economic impact on Montenegro's industrial sector. In the process of accession to the EU and in addressing global challenges, the country's industrial sector, in line with key development strategies, is heading towards reindustrialization, i.e. development and progress under changing conditions.

Published: May 2018

In this study, we aim to investigate the relationship between interest rate and inflation rate in the context of the Fisher effect hypothesis for Fragile five economies. In this regard, we employ recently developed panel co-integration and panel causality test methods. The bi-directional causal relation between interest rate and inflation rate exists only in Brazil and Indonesia. On the other hand, there is no causation linkage in India. Results imply that Fisher effect exists only in Brazil and Indonesia.

Ecological Scarcity Method: Adaptation and Implementation for Different Countries
Authors: Grinberg Marina , Ackermann Robert , Finkbeiner Matthias
Published: May 2018

The Ecological Scarcity Method is one of the methods for impact assessment in LCA. It enables to express different environmental impacts in single score units, eco-points. Such results are handy for decision-makers in policy or enterprises to improve environmental management.

So far this method is mostly used in the country of its origin, Switzerland. Eco-factors derive from the national conditions. For other countries sometimes it is impossible to calculate all ecofactors. The solution of the problem is to create a set of transformation rules. The rules should take into account the regional differences, the level of society development, the grade of scarcity and other factors. The research is focused on the creation of transformation rules between Switzerland, Germany and the Russian Federation in case of GHG emissions.
Las Victorias
Authors: Gallipoli Milena
Published: May 2018

La Victoria de Samotracia es una de las obras más reconocidas a nivel mundial. El museo del Louvre posicionó a la escultura como una pieza canónica gracias al protagonismo que adoptó en su museografía y, en paralelo, a través de la venta y puesta en circulación de calcos escultóricos en yeso producidos por su propio taller de vaciados. El objetivo del presente trabajo es vincular el caso de las copias de la Victoria de Samotracia con el consumo y exhibición de dos de sus ejemplares en el Museo Nacional de Bellas Artes (MNBA) y la Escuela Superior de Bellas Artes (ESBA) de Buenos Aires, ambas colecciones conformadas en las primeras décadas del siglo XX. Cotejar el rol que cada calco cumplió al interior de cada institución permitirá dilucidar las dinámicas de funcionamiento de un museo y de una instancia de formación artística. A través de un análisis del perfil institucional y las variaciones en la política exhibitiva se puede afirmar que en el contexto del museo hubo un desplazamiento de los calcos en general que tuvo como contrapartida el destaque de la Victoria de Samotracia como pieza aislada. Por otra parte, en la colección del Museo de Calcos de la ESBA, la obra se expuso en función de una construcción de un relato de la historia del arte que diese cuenta de una sucesión de estilos a través del tiempo.
Portuguese ambitions vs Japanese tradition
Authors: Tsoumas Johannis
Published: May 2018

The article aims at exploring the particularly enchanting – in terms of scientific research – historic area of the Nanban art period in Japan during which a new type of Japanese art emerged reflecting the scopes and intentions of the first European traders / Christian missioners who arrived in the southern part of the country in the mid sixteenth century. More precisely, it focuses on some of the most characteristic artifacts of the Portuguese daily way of life or religion which played a particularly important role in the imagination, ideology, consciousness and creativity of the locals who seemed to assimilate this new type of practical, aesthetic and religious information by transforming it to a new type of art and craft. But under which conditions were all these happened and what did these new objects mean? Were these objects used by the local communities or were they exported to Europe? What were the social and political, conditions in traditional Japan during this ‘cultural upheaval’ caused by the Portuguese traders and Jesuits? The article aims also at exemplifying questions of this type as the moving and transforming of objects in history is always associated with changes in the cultural physiognomy of societies.

Neste trabalho serão analisadas as relações entre o espaço arquitetônico do Pavilhão psicoativo - Tunga, localizado no Instituto Inhotim, com alguns objetos permanentemente expostos em seu interior sob a ótica do corpo em transformação. Uma vez que as obras do instituto também fazem parte de livros e de narrativas ficcionais criadas pelo artista, além de exposições anteriores à abertura do espaço expositivo, a presente análise buscará explorar a teia de inquietas potencialidades de interpretações que desdobram das obras dentro da concepção autorreferente/rizomática que Tunga propõe em sua poética. Esta abordagem analítica é fruto da pesquisa intitulada Instauração e Alquimia: o corpo em transmutação nos trabalhos de Tunga realizada entre os anos de 2014 e 2016 junto ao Programa de Pós-Graduação do Instituto de Artes da UNICAMP.
The (French) origins and development of international independent Art at the Musée du Jeu de Paume in 1937
Authors: Kangaslahti Kate
Published: May 2018

Em abril de 1937, Wassily Kandinsky, ressentido pelo fato de os artistas surrealistas e abstratos estrangeiros terem sido amplamente excluídos da Exposição Internacional, em Paris, daquele ano, aproximou-se do diretor do Musée du Jeu de Paume visando montar uma mostra de arte contemporânea. Três meses mais tarde, o museu inaugurou uma exposição de pequena escala, mas bastante ambiciosa: Origens e desenvolvimento da arte internacional independente propôs um amplo panorama da arte do século XX, mostrando para os espectadores seu desenvolvimento como uma sucessão de movimentos globais. Apesar das intenções grandiosas, a exposição no Jeu de Paume nunca realmente foi além de uma antologia da pintura parisiense e, por esse e outros motivos, foi uma fonte de conflito profissional e decepção pessoal para muitos. Retraçando os eventos no Jeu de Paume através de registros de arquivo e do material expositivo ainda existente e examinando aspectos da organização da mostra, de sua instalação e recepção crítica, este artigo reflete sobre o tênue lugar que a arte abstrata e os artistas nascidos no exterior ocuparam nos círculos culturais franceses no período entre guerras e explora as formas pelas quais a desconfiança crítica e institucional deu origem a intrigas.
Ecologías políticas
Authors: Rosauro Elena
Published: May 2018

En las últimas décadas, la sostenibilidad y la conservación de la naturaleza han escalado posiciones entre las mayores preocupaciones de la población del planeta. Año tras año vemos cómo los desastres naturales se repiten, la deforestación avanza y la extinción de numerosas especies animales y vegetales se acelera, debido no sólo a la contaminación de la atmósfera y a la extracción de recursos naturales (minería, caucho, madera, petróleo, etc.) sino también a la urbanización descontrolada, al turismo de masas, a la ganadería intensiva, a los monocultivos (transgénicos) y a los pesticidas. Abordaremos las obras de algunos artistas que muestran y/o denuncian estas prácticas ecocidas en territorio latinoamericano, como Ursula Biemann, Eduardo Molinari, Alejandro Meitlin o Abel Rodríguez. Y lo haremos con el doble objetivo de ofrecer, por un lado, un panorama de las prácticas artísticas cercanas al ecologismo y de reflexionar, por otro, en torno a la función social y política del arte en el siglo XXI.
O retrato em miniatura do gato Gatinho
Authors: Telles Patricia Delayti
Published: May 2018

Meio privilegiado de preservar a memória de seres queridos antes do advento da fotografia, o retrato em miniatura quase desapareceu no século XX. A miniatura do gato Micetto, “Gatinho” em italiano, encomendada em 1917 por seu antigo dono, o embaixador e escrito brasileiro Carlos Magalhães de Azeredo, desolado com a morte do seu animal favorito, é um raro exemplo da sobrevivência desse suporte. Este objeto ao mesmo tempo intimista e sofisticado permite-nos vislumbrar a vivência de certas elites cosmopolitas da Belle Époque, e o forte impacto afetivo desse tipo de retratos em plena “modernidade”.

Workplace Sexual Harassment and its Underreporting in Pakistan
Authors: Hadi Abdul
Published: May 2018

Sexual harassment in the workplace is a reflection of unequal power relationship among genders and should not be seen as isolated cases emanating from psychological or criminal roots. The practice of sexual harassment in the workplace occurs in occupations and industries which turns working environment for women into stressful, damaging, and hostile and makes it difficult for them to achieve their rightful place in employment. Sexual harassment in the workplace is the most frequent form of gender-based violence occurring in Pakistani society which is characterized by patriarchy and gender segregation. When women attempt to join workforce and take economic responsibilities of family in opposite to predominating social norms, they have to suffer from sexual harassment. This sort of unfriendly and hostile working environment for women disclose not only the gender-biased structure of the workplace but also ingrained and entrenched culture which objectify women and quite often paints her as mere recipients of male desire. The view of women’s objectification are reproduced and perpetuated in working environment of patriarchal societies. This study is an endeavor to find out the causes of sexual harassment in the workplace in Pakistan; and what are the underlying factors which lead to under-reporting of the incidences of sexual harassment. This study asserts that the patriarchal values prevailing in Pakistani society breed sexual harassment in the workplace and also preclude victims to report the incidence by not giving them appropriate moral, cultural and legal support. This study argues that in an environment like Pakistan where rule of law is not prevalent in entire society so just having policies and awareness regarding these policies could not be a valid and significant element for lowering the sexual harassment incidences. This phenomenon reflects the unequal power relationships between genders and cannot be combated until patriarchal mindsets are changed which can be achieved only by transforming the existing patriarchal society itself that is producing such mindsets.
Ring-Opening Hydroarylation of Monosubstituted Cyclopropanes Enabled by Hexafluoroisopropanol

Ring-opening hydroarylation of cyclopropanes is typically limited to substrates bearing a donor-acceptor motif. Here, the transformation is achieved for monosubstituted cyclopropanes by using catalytic Brønsted acid in hexafluoroisopropanol (HFIP) solvent, constituting a rare example where such cyclopropanes engage in intermolecular C–C bond formation. Branched products are obtained when electron-rich arylcyclopropanes react with a broad scope of arene nucleophiles in accord with a simple SN1-type ring-opening mechanism. In constrast, linear products are obtained when cyclopropylketones react with electron-rich arene nucleophiles. In the latter case, mechanistic experiments and DFT-calculations support a homo-conjugate addition pathway.
Conditioning–Free Electrolytes for Magnesium Batteries Using Sulfone–Ether Mixtures with Increased Thermal Stability
Authors: Merrill Laura C. , Schaefer Jennifer
Published: May 2018

We report an investigation of electrochemical properties and speciation of electrolytes composed of magnesium bis(hexamethyldisilazide) (Mg(HMDS)2) and magnesium chloride in sulfone-ether mixtures. The inclusion of sulfones dramatically increased the thermal stability of the electrolytes to 80 °C. The addition of ether was necessary to form an electrochemically active species. Electrochemical reversibility was maintained above 90% for 50 cycles for equivolume mixtures of butyl sulfone and THF. Sulfolane based solutions demonstrated low reversibilities and mass spectrometry measurements showed the preferential formation of an MgCl+ cation over the Mg2Cl3+ cation. Greater amounts of Mg2Cl3+ compared to MgCl+ is linked with higher performing electrolytes. Spectroscopic measurements showed co-solvation of the active magnesium cation with both solvents.

Fisherman accidentally caught sea turtles in their fishnet. It could be dangerous for its population. This study measures the turtle target strength (TS) using modified echosounder. The result could be used to improve the efficiency of turtle repellent device. The experiment conducted in a hatchery fiber tank contained saline water. The Green were 1, 3, 12 and 18 years old. The study used three species of fish to ensure there are no overlapped value between fish and sea turtle. TS of the animals were calculated incorporating reference targets (sphere). The echo power of the turtle was compared with the solid steel sphere which is confirmed good agreements with the theoretical values. The echo power reference by applying Fast Fourier Transform (FFT) analysis has been used in calculating TS of the animal. From the echo evaluation in time domain at different angles, it is obviously shown that echo signal structure is different between the parts of turtle body. This study reveals that high echo strength is acquired from the carapace and the plastron parts. The finding also showed that there are significant differences between 3, 12, 18 years old turtles and fish in every angle measurement.

Uso Da Enxertia Na Produção De Mudas De Meloeiro
Authors: Santos Marcos Paulo Dos , Furquim Leonnardo Cruvinel , Reges Nívea Patrícia Ribeiro , Nascimento Abadia Dos Reis
Published: May 2018

A enxertia surge no cenário de produção de hortaliças como estratégia de escape a condições adversas oriundas do cultivo contínuo destas plantas em uma mesma área durante praticamente todo o ano. A escolha dos materiais a serem usados como enxerto e porta-enxertos aliada ao tipo de enxertia definem o sucesso da técnica na produção de mudas comerciais. Dentre as vantagens proporcionadas pela enxertia destacam-se a possibilidade de aumento da resistência das plantas à patógenos de solo, salinidade, déficit hídrico e ainda incrementos na produtividade e qualidade de frutos. Para o melão, o maior gargalo no emprego da enxertia é a obtenção de porta-enxertos que se adaptem ao meio ambiente, não interfiram negativamente na qualidade dos frutos e mantenham a resistência às doenças por longo período de tempo. As causas de incompatibilidade na enxertia do meloeiro ainda não estão bem esclarecidas e respostas incompatíveis podem surgir mesmo após o transplantio. O incentivo ao rastreamento de combinações de porta-enxerto/enxerto para o melão figura como meio potencial para superar estas limitações, visto que a gama de porta-enxertos comercias é limitada, restringindo-se basicamente ao próprio meloeiro e as éspecies Cucurbita maxima e Cucurbita moschata.
