Isolation and Comparison of Molecular Properties of Cytochrome £-559 from Both Spinach Thylakoids and PS II Particles
Authors: Ortega José María , Hervás Manuel , Losada Manuel 
Published: September 2017

Abstract
Cytochrome b-559. Spinach Thylakoids. PS II Particles. High and Low Potential. Interconvertible Forms Cytochrome b-559 has been purified from both spinach (Spinacia oleracea L.) thylakoids and photosystem II particles in order to compare some of its more polemic molecular properties. In the two cases, cytochrome 6-559 (which is initially present in its reduced high-potential form and in its oxidized low-potential form) is purified as a single species by preparative disc electrophoresis in Triton-containing polyacrylamide gel, the isolated protein exhibiting similar molecular mass and almost identical low midpoint redox potential and absorption spectra. Moreover, sodium dodecyl sulfate polyacrylamide gel electrophoresis of the purified cytochrom e b-559 reveals, again in both cases, only one polypeptide band of similar molecular mass. Integration o f the isolated low-potential form into liposomes partly restores the high-potential form. These data corroborate our previous results and indicate that there exists in thylakoids only a cytochrome b -559 molecular species tightly bound to PS II and that the two naturally occurring low-and high-potential couples are physiological and correspond to interconvertible states of the genuine hem e protein.

Published: September 2017

Abstract
Structure and function of the QB-protein of a metribuzin resistant mutant of Chlamydomonas reinhardii were analyzed. The amino acid residue Leu-275 of the wild type protein is changed to Phe as was determined by RNA -sequence analysis. This mutation caused a 20-fold and 5-fold resistance to metribuzin and DCMU , respectively. No resistance to atrazine was observed. The kinetics of the electron transport from QA to OB was similar to that of the wild type (t1/2 = 0.4 ms).
Degradation of the 32 kDa Photosystem II Reaction Center Protein in UV, Visible and Far Red Light Occurs Through a Common 23.5 kDa Intermediate

Published: September 2017

Abstract
A characteristic 23.5 kD a degradation intermediate of the 32 kDa photosystem II reaction center protein is produced upon illumination in UV , visible and far red light. We suggest a similar degradation pathway is employed in these three spectral regions, even though the light can enter the system through different photo receptors.
Effect of Protocol Manipulation for Determining Maximal Aerobic Power on a Treadmill and Cycle Ergometer: A Brief Review
Authors: Julio Ursula F. , Panissa Valéria L. G. , Shiroma Seihati A. , Franchini Emerson 
Published: September 2017

ABSTRACT
THE DEVELOPMENT OF AEROBIC FITNESS IS CONSIDERED IMPORTANT FOR HEALTH AND PERFORMANCE. IN THIS SENSE, EVALUATION OF MAXIMAL AEROBIC POWER (MAP) BECOMES RELEVANT, NOT ONLY TO CLASSIFY AEROBIC FITNESS, BUT ALSO TO OBTAIN IMPORTANT INDICES RELATED TO MONITORING AND PRESCRIPTION OF EXERCISE, ESPECIALLY HIGH-INTENSITY INTERMITTENT EXERCISE. HOWEVER, IN THE LITERATURE, THERE ARE A VARIETY OF PROTOCOLS THAT MANIPULATE DIFFERENT VARIABLES, SUCH AS INITIAL LOAD, STAGE DURATION, INCREMENT LOAD, AND INCREMENTS BASED ON RATING OF PERCEIVED EFFORT. THEREFORE, THE AIMS OF THE PRESENT PAPER ARE TO ANALYZE STUDIES THAT MANIPULATE THE TEST PROTOCOLS AND THE EFFECTS ON INDICES RELATED TO MAP.
benefits of segmentation: Evidence from a South African bank and other studies
Authors: Breed Douw G. , Verster Tanja 
Published: September 2017

We applied different modelling techniques to six data sets from different disciplines in the industry, on which predictive models can be developed, to demonstrate the benefit of segmentation in linear predictive modelling. We compared the model performance achieved on the data sets to the performance of popular non-linear modelling techniques, by first segmenting the data (using unsupervised, semi-supervised, as well as supervised methods) and then fitting a linear modelling technique. A total of eight modelling techniques was compared. We show that there is no one single modelling technique that always outperforms on the data sets. Specifically considering the direct marketing data set from a local South African bank, it is observed that gradient boosting performed the best. Depending on the characteristics of the data set, one technique may outperform another. We also show that segmenting the data benefits the performance of the linear modelling technique in the predictive modelling context on all data sets considered. Specifically, of the three segmentation methods considered, the semi-supervised segmentation appears the most promising.

Significance:

The use of non-linear modelling techniques may not necessarily increase model performance when data sets are first segmented.
No single modelling technique always performed the best.
Applications of predictive modelling are unlimited; some examples of areas of application include database marketing applications; financial risk management models; fraud detection methods; medical and environmental predictive models.

Dispositif of creativity, gender and the precarisation of artistic work
The aim of this article is to open up theoretical perspectives to the research of the status of the artists and especially on its gender analysis. My principal points of references are the writings of a British cultural theorist Angela McRobbie and her concepts of disposi- tif of creativity and postfeminist sexual contract. The Foucauldian concept dispositif of creativity is used to illustrate how the features of artistic working conditions are in uenced by the wider and creativity-emphasizing current of changes taking place in the general sphere of production, therefore making the working conditions of the people working in the artistic sphere even more precarious. At the same time the model of “working like an artist” becomes a prominent feature not only in the creative sector but in other industries as well. All these features and transitions are also gendered in manifold ways. The concept of postfeminist sexual contract implies that the importance of young and highly educated women is constantly growing so that the so-called “top girls” have now become the ideal worker subjects of the post-Fordist era. This is not to say that gender inequality issues are disappeared, even though there is a certain kind of a post-feminist illusion of equality tak- ing place across the society. Because of this “postfeminist masquerade” the inequalities are being reshaped and therefore becoming more dif cult to grasp. In this article I will present the main features of these two concepts and use them to analyze the changes taking place in the Finnish context of artistic activity by referring to previous empirical research ndings implemented in the eld. As a conclusion I suggest that the increased amount of self-em- ployers and free artists in the Finnish artistic eld goes hand in hand with the growing importance of individualization implemented by the dispositif of creativity. This develop- ment also leads to new forms of gender inequality, such as the growing importance of the precarious or ‘untypical’ working position of working as a free artist, self-employer or entrepreneur as an explanatory factor of the income gap between male and female artists.

Understanding Audiences and the Impact of Arts and Culture: Experience as the Focus of Audience Research
What are the meanings that people give to justify their attendance or non-attendance in culture and arts? What kind of experiences lie behind these justifications? Although there is a vast amount of knowledge on attendance and participation in culture and art, it is usually produced from the perspective of the goals of cultural administration. Therefore, in this article I suggest addressing the questions on attendance and non-attendance, participation and impact of arts and culture by focusing on the experiences of audiences. Instead of trying to develop quantitative measurements for the impact of arts and culture, the experiences of people should be understood more thoroughly. I reflect on what qualitative audience research with creative methods could provide for research as well as the development of cultural policy and public funding.
Key words: qualitative audience research, audience experience, impact of culture and art, creative methods
INFLUENCE OF METRONIDAZOLE ON BIOLOGICAL ACTION OF DOXORUBICIN

Published: September 2017

Purpose. Investigation of the effect of the Metronizatol on the biological effect of Doxirubicin.Materials and methods. The studies were performed in the CBA/Lac males and C57Bl/6 females mice grafted with melanoma B16 and mucinous ovarian cancer CaO‑1. Metronidazole and Doxorubicin were used in the work. The antitumor effect was assessed by tumor volume and inhibition of tumor growth.Results. The data obtained indicate that Metronidazole used in oncologic practice for the treatment and prevention of infectious complications, and as a radiosensitizer, can enhance the antitumor effect of Doxorubicin, but this effect is accompanied by a significant increase of the cytostatic toxicity. These effects are leveled by increasing the interval between injections of Metronidazole and Doxorubicin up to 4 hours.Conclusion. The enhancement of the antitumor activity of Doxorubicin under the influence of Metronidazole depends on the interval between the administration of these drugs. When Metronidazole is used in cancer patients, the possibility of enhancing the toxic effect of cytostatics should be considered when they are simultaneously exposed. Patients receiving chemotherapy should be administered antitumor drugs no earlier than 4 hours after exposure to Metronidazole.
Mídia impressa na educação a distância: possíveis contribuições da teoria da relevância
Authors: Caldeira Fátima Hassan 
Published: September 2017

O artigo apresenta resultados provisórios de pesquisa fundamentalmente teórica acerca das possíveis contribuições da Teoria da Relevância de Sperber e Wilson (1986, 1995) para a produção de material didático impresso para os cursos de Educação a Distância (EaD). Esse estudo justifica-se porque, apesar de todos os avanços tecnológicos no campo da informação e comunicação, pesquisas constatam que a mídia impressa ainda é a mais utilizada pelos alunos dos cursos a distância. Ao afirmar que as estratégias de ensino-aprendizagem são, essencialmente, relações de comunicação, Rauen (2003) abre espaço para a utilização da Teoria da Relevância, como teoria de comunicação, na relação professor-aluno, inclusive a mediatizada pelo texto. Rauen (2003) destaca que a tradicional perspectiva de educação, coerente com as teorias de código, que define o papel do professor como transmissor de conhecimentos e o aluno como receptor desses conhecimentos, não é adequada diante de uma explicação ostensivo-inferencial da comunicação. Assim, a partir dessa perspectiva, é necessário que se reconheça que existe um hiato entre o que se ensina e o que se aprende e que este deve ser preenchido por inferências. Pelo fato de a relação professor-aluno, nessa modalidade de ensino, ser assíncrona e mediada pelo texto e porque toda a relação de ensino-aprendizagem pressupõe um processo colaborativo e interativo entre professor e aluno, é necessário que a produção da mídia impressa antecipe e simule raciocínios abdutivos acerca das possíveis interações professor-aluno, buscando contextualizar a experiência do discente a partir dos seus conhecimentos prévios. Diante disso, crê-se que a Teoria da Relevância pode dar aporte ao professor-autor (ou conteúdista) para a produção de mídia impressa para EaD.
L’imaginaire de l'apocalypse, le septénaire: sens et symboles
Authors: Bertin Georges 
Published: September 2017

Angers é cidade do Apocalipse, assim testemunham as obras de arte que ao longo de séculos foram lá fixadas, pórtico e rosáceas dos transeptos da Catedral Saint Maurice (século XIII), tecido decorativo do Apocalipse de Angers (século XIV), tapeçaria Le Chant du Monde de Jean Lurçat (século XX, etc.). A releitura de São João, a observação das obras nos conduzem a pensar que a matéria apocalíptica é do domínio do imaginário. Ela desvela, no sentido da palavra apocalipse, a profundidade do imaginário escondido no coração das nossas sociedades, oriundos, entre fé e saber, deste mundus imaginalis do qual fomos, há muito tempo, separados. Vamos aqui considerar o tema do septenário que lá está é muito recorrente. Nesta base, vemos como o Apocalipse fixa uma temática arquetipal ao alcance universal

Polifonia de Vozes: o ‘multicultural planning’ como método de avaliação de políticas culturais produzidas no espaço urbano
Authors: Domingues João Luiz Pereira 
Published: September 2017

O artigo se dedica à reflexão em torno da relação entre as políticas culturais, a esfera pública e seus desdobramentos territoriais, tendo como acento a discussão metodológica. O que o artigo propõe ressaltar é a possibilidade de que certos grupos e indivíduos sejam invisibilizados ou não tematizados pela aparência consensual das políticas culturais. Desta feita, tenta-se aqui traduzir um modelo metodológico de planejamento urbano para fins de diminuição do risco de atrofia de expressões culturais na cidade. Ao tematizar o universo cultural na teoria do planejamento, o Multicultural Planning rejeita a adoção dos modelos de racionalidade instrumental em favor de um modelo de reconhecimento de experiências que ressaltam diferentes leituras sobre a construção da realidade e das diversas possibilidades de organização de práticas coletivas de administração e planejamento urbano e cultural.

Published: September 2017

Objectives. To evaluate 2-year changes in soda consumption, weight, and waist circumference. Methods. We followed 11 218 women from the Mexican Teachers’ Cohort from 2006 to 2008. Dietary data were collected using a semiquantitative food frequency questionnaire. Weight was self-reported, and waist circumference was self-measured. We used linear regression to evaluate changes in sugar-sweetened and sugar-free soda consumption in relation to changes in weight and waist circumference, adjusting for lifestyle and other dietary factors. Results. Compared with no change, a decrease in sugar-sweetened soda consumption by more than 1 serving per week was associated with less weight gain (−0.4 kg; 95% confidence interval [CI] = −0.6, −0.2). Conversely, relative to no change, an increase in sugar-sweetened soda by more than 1 serving per week was associated with a 0.3-kilogram (95% CI = 0.2, 0.5) increase in weight. An increase of 1 serving per day of sugar-sweetened soda was associated with a 1.0 kg (95% CI = 0.7, 1.2; P < .001) increase in weight. The results for waist circumference were similar. Conclusions. Moderate changes in consumption of sugar-sweetened soda over a 2-year period were associated with corresponding changes in weight and waist circumference among Mexican women.

Published: September 2017

Objectives. To examine the extent to which law enforcement agencies (LEAs) and gun retailers are willing to offer voluntary, temporary storage as a part of an overall suicide prevention effort. Methods. We invited all LEAs and gun retailers in 8 US states to respond to questionnaires asking about their willingness to offer temporary gun storage and their recommendations to gun owners about safe storage. Results. We collected data in 2016 from 448 LEAs and 95 retailers (response rates of 53% and 25%, respectively). Three quarters of LEAs (74.8%; 95% confidence interval [CI] = 72.1, 77.5) indicated they already provided temporary storage compared with 47.6% (95% CI = 39.2, 56.0) of retailers. LEAs were most willing to provide storage when a gun owner was concerned about the mental health of a family member. Retailers were more receptive than were LEAs to providing storage when visitors were coming or for people wanting storage while traveling. Both groups recommended locking devices within the home, but LEAs were slightly more favorable to storing guns away from the home. Conclusions. Law enforcement agencies and gun retailers are important resources for families concerned about suicide.
Enrollment in California’s Medicaid Program After the Affordable Care Act Expansion
Authors: Wang Jing , Trivedi Amal N. 
Published: September 2017

Objectives. To determine enrollment rates and predictors of enrollment for newly eligible low-income adults in California following the Affordable Care Act’s (ACA’s) Medicaid expansion. Methods. We used data from the 2014 to 2015 California Health Interview Survey to examine post-ACA Medicaid enrollment rates and multivariable logistic regression to assess the association of demographic factors, income, and health with enrollment. Results. We found a 78.5% enrollment rate for the newly eligible Medicaid population, translating to 3.8 million adults enrolled and 1.1 million adults who were eligible but did not enroll. Significant predictors of enrollment were participating in a public welfare program (odds ratio [OR] = 6.59; 95% confidence interval [CI] = 3.09, 14.04), having heart disease (OR = 4.03; 95% CI = 1.34, 12.15), being in the top quartile of income (OR = 3.59; 95% CI = 1.64, 7.85), enrolling in 2015 (OR = 3.28; 95% CI = 1.94, 5.56), being unemployed (OR = 2.10; 95% CI = 1.15, 3.82), and being female (OR = 1.71; 95% CI = 1.03, 2.85). We did not find significant disparities across race/ethnicity, education level, or geography. Conclusions. Repeal of Medicaid expansion would have a substantial effect on health insurance coverage among California’s low-income adults, many of whom report chronic health conditions and no alternative sources of affordable coverage. Future research should examine the mechanisms explaining the higher enrollment rates among California’s Medicaid expansion population.
Assessing the Yield and Load of Contaminants with Stream Order: Would Policy Requiring Livestock to Be Fenced Out of High‐Order Streams Decrease Catchment Contaminant Loads?
Authors: McDowell R. W. , Cox N. , Snelder T. H. 
Published: September 2017

Catchment contaminant loads vary with stream order as catchment characteristics influence inputs and in‐stream processing. However, the relative influence and policy significance of these characteristics across a number of contaminants and at a national scale is unclear. We modeled the significance of catchment characteristics (e.g., climate, topography, geology, land cover), as captured by a national‐scale River Environment Classification (REC) system, and stream order in the estimation of contaminant yields. We used this model to test if potential regulation in New Zealand requiring livestock to be fenced off from large (high)‐order streams would substantially decrease catchment contaminant loads. Concentration and flow data for 1998 to 2009 were used to calculate catchment load and yields of nitrogen (N) and phosphorus (P) species, suspended sediment, and Escherichia coli at 728 water quality monitoring sites. On average, the yields of all contaminants increased with increasing stream order in catchments dominated by agriculture (generally lowland and pastoral REC land cover classes). Loads from low‐order small streams (<1 m wide, 30 cm deep, and in flat catchments dominated by pasture) exempt from potential fencing regulations accounted for an average of 77% of the national load (varying from 73% for total N to 84% for dissolved reactive P). This means that to substantially reduce contaminant losses, other mitigations should be investigated in small streams, particularly where fencing of larger streams has low efficacy.Core Ideas
Contaminant yields increased with increasing stream order in catchments dominated by agriculture.
Fencing off high‐order streams from stock misses 77% of national contaminant load from small‐order streams.
Hence, to reduce contaminant losses to small streams, other mitigations are needed.
