Background and objectives

Higher fruit and vegetable intake is associated with lower cardiovascular and all-cause mortality in the general population. It is unclear whether this association occurs in patients on hemodialysis, in whom high fruit and vegetable intake is generally discouraged because of a potential risk of hyperkalemia. We aimed to evaluate the association between fruit and vegetable intake and mortality in hemodialysis.

Design, setting, participants, & measurements

Fruit and vegetable intake was ascertained by the Global Allergy and Asthma European Network food frequency questionnaire within the Dietary Intake, Death and Hospitalization in Adults with ESKD Treated with Hemodialysis study, a multinational cohort study of 9757 adults on hemodialysis, of whom 8078 (83%) had analyzable dietary data. Adjusted Cox regression analyses clustered by country were conducted to evaluate the association between tertiles of fruit and vegetable intake with all-cause, cardiovascular, and noncardiovascular mortality. Estimates were calculated as hazard ratios with 95% confidence intervals (95% CIs).

Results

During a median follow up of 2.7 years (18,586 person-years), there were 2082 deaths (954 cardiovascular). The median (interquartile range) number of servings of fruit and vegetables was 8 (4–14) per week; only 4% of the study population consumed at least four servings per day as recommended in the general population. Compared with the lowest tertile of servings per week (0–5.5, median 2), the adjusted hazard ratios for the middle (5.6–10, median 8) and highest (>10, median 17) tertiles were 0.90 (95% CI, 0.81 to 1.00) and 0.80 (95% CI, 0.71 to 0.91) for all-cause mortality, 0.88 (95% CI, 0.76 to 1.02) and 0.77 (95% CI, 0.66 to 0.91) for noncardiovascular mortality and 0.95 (95% CI, 0.81 to 1.11) and 0.84 (95% CI, 0.70 to 1.00) for cardiovascular mortality, respectively.

Conclusions

Fruit and vegetable intake in the hemodialysis population is low and a higher consumption is associated with lower all-cause and noncardiovascular death.

Surface mechanography (MMG) is a non-invasive technique that captures signs of low-frequency vibrations of skeletal muscles through the skin. However, subcutaneous structures may interfere with the acquisition of MMG signals. The objective of this study was to verify the influence of skinfold thickness (ST) on the MMG wavelet-based signal in the rectus femoris muscle during maximal voluntary contraction in two groups of individuals: group I (n = 10, ST <10 mm ) and group II (n = 10, ST equal to or> 20 mm). Negative correlation was observed between the 19 Hz, 28 Hz and 39 Hz frequency bands with ST. There was a statistical difference in almost all frequency bands, especially in the X and Y axes. All MMG axes in group II presented higher magnitudes in frequency bands 2 and 6 Hz (like low-pass filter). Thus, these results can be applied to calibrate MMG responses as biofeedback systems.

The geometric modeling of a personalized part of the tissue built according to individual morphology is an essential requirement in anatomic prosthesis. A 3D model to fill the missing areas in the skull bone requires a set of information sometimes unavailable. The unknown information can be estimated through a set of rules referenced to a similar yet known set of parameters of the similar CT image. The proposed method is based on the Cubic Bezier Curves descriptors generated by the de Casteljou algorithm in order to generate a control polygon. This control polygon can be compared to a similar CT slice in an image database. The level of similarity is evaluated by a meta-heuristic fitness function. The research shows that it is possible to reduce the amount of points in the analysis from the original edge to an equivalent Bezier curve defined by a minimum set of descriptors. A study case shows the feasibility of method through the interoperability between the prosthesis descriptors and the CAD environment.

Published: January 2019

Development and improvement of 3D digitizing systems provide for the ability to digitize a growing number of materials and geometrical forms of greater complexity. This paper presents the application of 3D digitizing system using close range photogrammetry on the upper jaw cast in plaster in order to obtain its 3D model. Because of the low visual characteristics of gypsum, such as color and texture, many questions arise about the possibility of applying this particular method to this type of physical models. In order to overcome bad visual properties of gypsum, this paper analyzes the possibility of the photogrammetry method application supported by the projected light texture which is based on patterns in the form of noise-obtained  mathematically modeled functions. In order to determine the selected image for light texture which gives the better results, an experiment was designed and carried out. Only two images were tested. One image is selected based on previous research and the other one was generated by the Matlab function for uniformly distributed random numbers. For validation and a comparative analysis of the results, an object of 3D digitization was generated with and without projected light texture. CAD inspection was applied for the analysis of the obtained 3D digitizing results. 3D model obtained by approved professional optical 3D scanner as a reference was used. The results in this paper confirm better accuracy of 3D models obtained with the use of light textures, but this approach requires additional hardware and setup adjustment for images acquisition.

Authors: Saleem Tooba , Mahmood Nasir
Published: January 2019

The nature of supervisory relationship is dynamic that changes over the course of candidacy. Subsequently, the supervision demands of supervisees also change to help them in performing certain tasks at specific research stages. In this context, this research is proposed to investigate the supervision experiences of supervisees in four different research stages (i.e. Stage 1: developing synopsis, Stage 2: collecting data, Stage 3: writing thesis and Stage 4: submitted thesis). In the light of six supervision aspects (i.e. Project management, Intellectual support, pertinent research skills, Inter-personal communication skills, Workload management and Supportive skills) the quality of supervision was assessed from supervisees’ perspective. Cross-sectional survey design was used to assess the supervision experiences of (N=422) supervisees in four distinct stages of research supervision. The data were collected from 12 public and private universities of the Punjab. For this study, a multi-sectioned, self-constructed Supervisor-Supervisee Relationship Questionnaire (Saleem, 2014) was used. The findings of the study highlighted the need to train the supervisors to manage their time not just in terms of teaching and supervision of research students, but also keeping the stages of their research in mind. By addressing the stage specific needs of supervisees the quality of supervision could be improved.

Self-Assessment of Students’ Anxiety during High Stake Laboratory Work Examinations
Authors: SHAH Ashfaque Ahmad , Hussain Shafqat , Syeda Zunaira Fatima , Sarwar Muhammad
Published: January 2019

The present study intends to explore the level of practical examination anxiety
among secondary and higher secondary school students and its causes and
remedies. A self-developed Perceived Science Practical Anxiety Scale (PSPAS)
was used to collect quantitative data from 900 science students of two districts of central Punjab: Sargodha and Faisalabad. Moreover, 50 students were interviewed to explore their perceptions of the causes of science practical examination anxiety and the remedies to reduce it. All students had recently taken science practical examination and therefore had first-hand vivid experience of science practical examination anxiety. The analysis of responses in the questionnaire revealed that on an average more than half (61.50 %) of the students experienced anxiety during practical examination. Fourteen sources of anxiety during practical examination were ranked and synthesis of qualitative data from interviews recorded five categories of anxiety causes: shortage and unavailability of the materials, lack of practice, harsh behaviour of laboratory personnel, over loaded syllabus and lack of guidance. The students’ opinion regarding reducing anxiety was synthesized into four themes: relaxation during practical examination, individual level preparation, completion of practical syllabus well before time and training of laboratory personnel. The findings of the study may be beneficial for teachers, school mangers and policy makers and those who are responsible for the preparation and execution of examination policies, to reduce anxiety among students.

Effects of the environmental characters on germination properties of seeds of Thymus daenensis and T.vulgaris
Authors: Yadegari Mehrab
Published: January 2019

This research was conducted to investigate the effects of salinity,
temperature, pH and sowing depth on germination characters of two species of
thyme in 2017. Two separate experiments with four replications using a
randomized complete design were conducted in laboratory conditions.
Treatments contained: a) fluctuating temperatures in a germinator 5/15,
10/20, 15/25, 15/30 and 20/3500C (day/night), b) concentrations of salinity
by using solutions of 0, 10, 20, 40, 80, 160 and 320 mM NaCl, c) sowing
depths of 0, 1.5, 3 and 6 cm, pH values of 5, 6, 7, 8 and 9. Results showed
that the effects of different treatments were significant on germination
percentage, germination rate and seed vigour. In most cases, upper
concentrations of treatments had negative effects on germination indices.
The emergence decreased with an increased concentration of salinity,
planting depth and pH. In both species, the highest germination percentage
(94%) was obtained in the combination treatment of 15/25C (day/night), 0 mM
of NaCl, 1 cm of planting depth and pH=7. Germination was stopped in the
combination of treatments of 35/20 (day/night), 320mM of NaCl, 6 cm of
planting depth and pH=9. The combination of treatments in the upper level
had a more inhibitory and destructive effect than single treatments.
Assessment of Striga resistance in wild relatives of sorghum under field conditions
Authors: Gamar Yasir , Bakhit Omer , Murdi Hatim , Adam Elfadil
Published: January 2019

The witch-weeds (Striga spp.) are destructive root parasites of many crops.
They result in considerable crop damage, especially in the semiarid tropic
parts of the world. The parasite control is difficult due to the complexity
of the parasite life cycle, and the large number of seeds produced by the
parasite with prolonged viability. The most promising way of controlling the
parasite is through the development of the resistant crop varieties.
Identification of different sources of resistance will enhance breeding for
resistant varieties. Wild relatives of sorghum are rich in genetic diversity
and have a broad genetic base including novel and valuable traits like
Striga and disease resistance. In this context, 55 wild sorghum lines were
collected from three regions of Sudan including eastern Sudan (Gadaref),
central Sudan (Gezira), and western Sudan (North Kordofan). The collected
germplasm was assessed for Striga resistance using artificial infestation.
The results showed a significant difference in the number of Striga emerged
plants compared to the checks. Hence, the significant difference was
observed in the number of days to 50% plants to reach flowering, plant
height, and grain yield per hectare. The wild relatives were also
morphologically characterized and the result showed 55 lines structured in
six groups independently from their geographical regions.

Published: January 2019

The preparation of MgO bearing iron ore pellets in the mini and pilot scales, and the application for 4070m3 blast furnace were conducted in this paper. The results show that with increasing the MgO content, the compressive strength of fired pellets decreased significantly, while the metallurgical performances, such as RI (reducibility index), RDI (reduction degradation index) and RSI (reduction swelling index) were improved. The scanning electron microscope with energy dispersive spectrometry was used to test the microstructures and the compositions of iron oxide, and the slag of pellets. With increasing the MgO content, MgO exists in the form of magnesium ferrite and monticellite, which presents the high melting temperature, decreasing the content of liquid phase. The pilot scale experiment was performed on a commercial running grate-rotary kiln with the annual output of 2.4 million tons of pellets, which agrees with the results obtained in the mini scale experiment. The application of MgO-bearing pellets was carried out in the 4070 m3 blast furnace of Meisteel China, and the production indexes improved with increasing the yield and reducing the coke ratio, and the total benefits are 7067 USD/d, which presents the superior economic benefits.

Published: January 2019

Objectives:

This study evaluated the effect of toothbrushing with a dentifrice on gloss, roughness profile, surface roughness, and wear of conventional and bulk-fill resin-based composites.

Methods and Materials:

Gloss and surface roughness of resin-based composites (RBCs; Admira Fusion X-tra, Aura Bulk Fill, Filtek Bulk Fill Flowable, Filtek Bulk Fill Posterior Restorative, Filtek Supreme Ultra, Herculite Ultra, Mosaic Enamel, SDR flow+, Sonic Fill 2, Tetric EvoFlow Bulk Fill and Tetric EvoCeram Bulk Fill) were analyzed before and after brushing; the roughness profile and wear were also determined after toothbrushing. Representative three-dimensional images of the surface loss and images comparing the unbrushed and brushed surfaces were also compared. Analysis of variance and Tukey post hoc tests were applied (α=0.05) to the gloss, surface roughness, roughness profile, and surface loss data. Pearson's correlation test was used to determine the correlation between gloss and surface roughness, surface loss and percentage of gloss decrease after brushing, and surface loss and surface roughness after brushing.

Results:

For all RBCs tested after 20,000 brushing cycles, the gloss was reduced and the surface roughness increased (p<0.05). However, the roughness profile and the amount of surface loss were dependent on the RBC brand. Admira Fusion X-tra, Aura, Tetric EvoCeram Bulk Fill, and Tetric EvoFlow Bulk Fill showed the deepest areas of wear (p<0.05). A significant negative correlation was found between gloss and surface roughness, and a weak correlation was found between the decrease in gloss and the extent of surface loss, and any increase in surface roughness and the surface loss.

Conclusions:

Toothbrushing with a dentifrice reduced the gloss, increased the surface roughness, and caused loss at the surface of all the RBCs tested. Considering all the properties tested, Mosaic Enamel exhibited excellent gloss retention and a low roughness profile and wear, while Admira Fusion X-tra exhibited the greatest decrease in gloss, the highest roughness profile, and the most wear.

Durante a realização da pesquisa de Doutorado, identificamos que o Teorema de Pitágoras é utilizado para justificar técnicas de construção de ângulos retos em terrenos planos, quando se utiliza trena e balizas. Essa realidade proporciona aos alunos uma razão de ser para o estudo desse saber matemático. O objetivo desse texto é discutir a relação institucional e a relação pessoal para o referido saber. Propomos duas tarefas para alunos do 1º ano do ensino médio, ambas estão relacionadas ao Teorema de Pitágoras. Utilizamos a noção de praxeologia para analisar as relações institucionais presentes em Brasil (1998) e a noção de praxeologia pessoal na análise das técnicas apresentadas pelos alunos. Os resultados apresentaram técnicas pessoais diferentes daquelas preconizadas pela instituição ensino de matemática.
During the doctoral research, we identified that the Pythagorean Theorem is used to justify techniques of construction of right angles in flat lands, when using trena and beacons. This reality gives students a raison d'être for the study of this mathematical knowledge. The purpose of this text is to discuss the institutional relationship and the personal relation to this knowledge. We propose two tasks for students in the 1st year of high school, both of which are related to the Pythagorean Theorem. We use the notion of praxeology to analyze the institutional relations present in Brazil (1998) and the notion of personal praxeology in the analysis of the techniques presented by the students. The results presented personal techniques different from those recommended by the teaching institution of mathematics.

Este texto trata de parte de uma investigação sobre o problema da infraestrutura de conhecimentos necessária para o desenvolvimento da modelagem matemática escolar sobre problemas em contexto. Para isso é proposto o ciclo investigativo de modelagem matemática como dispositivo inspirado nos cinco gestos que caracterizam uma verdadeira pesquisa a luz da teoria antropológica do didático. Resultados obtidos a partir da analise empírica sobre um problema em contexto, mostram a potencialidade do ciclo investigativo de modelagem matemática para aquisições de novos saberes úteis, senão indispensáveis a professores em formação, bem como encaminha futura investigação.
This paper is part of an investigation on the problem of knowledge infrastructure necessary for the development of school mathematical modeling on problems in context. For this, the research cycle of mathematical modeling is proposed as a device inspired by the five gestures that characterize a real research in the light of the anthropological theory of the didactic. Results obtained from the empirical analysis of a problem in context show the potential of the mathematical modeling research cycle for the acquisition of new useful knowledge, if not indispensable to teachers in formation, as well as forwards future research.
Um Modelo Epistemológico de Referência para o estudo da planificação de superfícies de pirâmides triangulares
 An Epistemological Model of Reference for the study of the planning of surfaces of triangular pyramids
Authors: Da Silva Maria José Ferreira , Almouloud Saddo Ag
Published: January 2019

Retomamos neste artigo um anteriormente publicado no sentido de ampliar as discussões lá propostas analisando a situação a partir de outro referencial. Trata-se da apresentação de um Modelo Epistemológico de Referência (MER) para a construção, no Geogebra, de planificações de superfícies de pirâmides triangulares de altura determinada, verificando condições e restrições para a referida construção. Tal MER pode justificar organizações didáticas que promovam Atividades de Estudo e Pesquisa (PEP) desenvolvidas a partir de questionamentos realizados durante a atividade que conduzirão a resolução do problema proposto. Um dos objetivos do estudo é proporcionar uma razão de ser para o trabalho com a representação plana de sólidos geométricos.
In this paper we have taken back a previously published one in order to broaden the discussion considering another referential. It refers to an Epistemological Model of Reference (EMR) for the construction of surface planning of triangulated pyramids of determined height, verifying conditions and restrictions using Geogebra. EMR can justify pedagogic organization that enable the method Study and Research Activities (SRA), which is developed from questions emerging that will lead to the resolution of the proposed problem. The main objective of the study is supporting the surface representation of geometric solids work.

Uma história de regressos: sobre Ó mar de túrbidas vagas, de Henrique Teixeira de Sousa
Authors: Moreira Fernando , Ribeiro Orquídea , Pimenta Susana
Published: January 2019

Henrique Teixeira de Sousa desenvolve na obra Ó mar de túrbidas vagas uma história de regressos cujo pano de fundo é a emigração cabo-verdiana para os Estados Unidos da América. De forma subtil, o autor reflete sobre aspetos da identidade cabo-verdiana num cruzamento bem-sucedido entre a sua escrita e os versos do poeta Eugénio Tavares, que cita de modo recorrente, e cujas palavras enformam esta história de regressos. Refletir sobre a obra de Henrique Teixeira de Sousa, a sua visão sobre a cabo-verdianidade e, em particular, sobre a emigração e os efeitos socioculturais consequentes tomando como ponto de partida o romance Ó mar de túrbidas vagas é o objeto de estudo que se propõe.
O sujeito órfico no Livro de Memórias, de Teixeira de Pascoaes: lembrança, desejo e saudade
Authors: Ressurreição Jorge Filipe
Published: January 2019

O Livro de memórias, de Teixeira de Pascoaes, retrata um mundo, o do narrador, povoado de lembranças que se presentificam constantemente por serem parte integrante daquele que narra. Para isso, o autor usa vários processos retóricos que o auxiliam na sua acção de evocar o passado. Contudo, mais do que simplesmente evocar, o sujeito pretende retirar das amarras do passado as imagens que compõem a sua memória e trazê-las de novo para junto de si, "dissipa[r] as trevas do tempo e ressuscita[r] os mortos", como diz o próprio. Deste modo, propomo-nos atentar no sujeito do primeiro capítulo do Livro de memórias como um sujeito órfico, que, pela escrita, pretende trazer a sua Eurídice — isto é, a sua infância ou as imagens que a compõem — de volta ao tempo presente, resgatando-a do passado (o Inferno). A aproximação do sujeito do Livro de memórias à personagem mítica de Orfeu pretende ser um contributo para o entendimento de um livro que, inserindo-se no género memorialístico, em quase tudo foge às características que esperaríamos encontrar numas memórias de autor.
A escritura como hospitalidade em A queda do céu, de Davi Kopenawa e Bruce Albert
Authors: Correia dos Santos Carolina
Published: January 2019

Davi Kopenawa e Bruce Albert realizam juntos A queda do céu: palavras de um xamã yanomami. Considerado uma profecia, este livro de autoria complexa dá conta de um mundo (não só yanomami) visitado, colonizado, catequizado, invadido, defendido, ameaçado. O outro, aí, é o napë, palavra que passa a se referir ao conceito de branco, além de inimigo e estrangeiro. A partir da relação entre Kopenawa e Albert, proponho ler A queda do céu como performance que visa uma hospitalidade ainda desconhecida, que dissolveria o paradoxo mesmo que a constitui: pois aquele que é hospitaleiro deve ser o dono da casa, o proprietário, aquele que tem direito a um território e que, assim, o abriria ao outro. Minha hipótese é de que a hospitalidade por vir de Jacques Derrida seja possível hoje para um Yanomami e na relação que ele impõe a quem acorda, aos que dizem um tipo de "sim" no ato de ler A queda do céu. Ademais, A queda do céu, com sua origem múltipla, humana e não humana, corrobora uma autoria que desmente a propriedade e que impele o leitor a uma tomada de posição.
