Fluorescence angiography for blood flow assess during right hemicolectomy. Case study
Authors: A. V. Malinovsky  , M. M. Mayorenko  , A. S. Sergievа  
Published: July 2018

Fluorescent laparoscopy enables to visualize blood vessels and blood flow in the organs of the gastrointestinal tract, which can be used in colon resection. Laparoscopic right hemiclectomy was performed in a patient aged 55 years with an adenomatous polyp of Bauginia flap without dysplasia. The operation was performed through four trocars: 1 — 10 mm, 1 — 13 mm, 2 — 5 mm. During surgery, the hepatic flexure of the colon was saved due to the expressed a. colica dextra. After intracorporal ileotransversoanastomosis formation of with the device Endo GIA‑60 fluorescence angiography was performed: Indocyanine green in a dose of 0.3 mg/kg of body weight was injected intravenously. After 2 minutes, in near‑infrared survey regime, a satisfactory vascularization of the terminal ileum mesentery and accumulation of the fluorescing substance in the walls of the ileum and the stomach stump, in particular the finite regions of the stump, have been achieved. Regarding the received data, there was no risk of failure of anastomosis and bowel stump. The operation was completed on a planned extension. No technical difficulties with fluorescence angiography were found. Allergic reactions to the administered drug and the failure of anastomosis were not. The first experience of using fluorescence angiography for assessing blood supply in the anastomosis area during resection of the colon demonstrated the convenience and safety of the technique. Fluorescence angiography helped to evaluate the blood supply to intestinal walls and mesentery, which allowed to execute a limited variant of operation with the preservation of hepatic flexure of the colon with blood supply from a. colica dex.
Microstructural characterization and residual stress distribution in a nanostructured austenitic stainless steel
Authors: Krawczynska Agnieszka T. , Lewandowska Malgorzata , Fry Anthony T. 
Published: July 2018

Abstract
In this paper, residual stress distribution is investigated by a novel X-ray cosα diffraction technique in a nanostructured austenitic stainless steel after hydrostatic extrusion processes. Hydrostatic extrusion performed at 20°C and with a total true strain of 2.3 leads to the creation of a nanostructure consisting of nanotwins and shear bands. The results reveal that the greatest compressive residual stresses of −1 GPa are found 3 mm from the surface of the nanostructured austenitic stainless steel. These compressive residual stresses restrict crack growth into the material, thereby preventing catastrophic failure.
First evidence of grain boundary serration in a specifically heat treated wrought Alloy 625 Ni-based superalloy
Authors: Terner Mathieu , Lee Ji-Won , Kim Jin-Hyeok , Hong Hyun-Uk 
Published: July 2018

Abstract
Grain boundary serration is an effective way to increase the high temperature resistance of superalloys and steels. The popular Alloy 625 Ni-based superalloy was until now believed not to form serrated grain boundaries based on previous considerations of serrability criteria. Following the recent strain-induced serration mechanism, a special heat treatment involving continuous slow cooling between the solution and aging temperature was designed. As a result, significant serration was observed for the first time for Alloy 625 promoted by slow cooling. Grain boundary M
23C6 carbides were systematically detected from either degenerescence of solidification MC carbides or heterogeneous nucleation. Upon aging, serration amplitude increased and precipitation of the δ phase proliferated.

Authors: Ardayati Ardayati 
Published: July 2018

The aim of this research was to find out whether or not it was significantly effective to use film as a media in teaching writing for tertiary level students. This study used preexperimental method which was focused on writing skill at the eleventh grade students of Senior High School Tugumulyo. The writer formulated two hypotheses; they were null hypothesis (Ho) and the alternative hypothesis (Ha). There were 352 students from nine classes as the population of this study. The sample was taken through cluster random sampling. The result was XI IA.2 class which consisted of 37 students. In this case, the writer collected the data by using writing test. Based on the findings, the result showed that tobtained was 6.38 where ttable was 1.697. It showed that tobtained was higher than ttable (tobtained more than ttable). Finally, the writer concludes that it was significantly effective to use film as media in teaching writing at the eleventh grade students of Senior High School Tugumulyo.

Estimation of Serum Iron and Ferritin in Patients with Chronic Renal Failure
Authors: Mohammed Rihab Akasha , Siddig Sara M. , Mahdi Mohammed A. , Babiker Adil A. 
Published: July 2018

Background: The incidence of renal failure, and potentially of CRF, is increasing steadily in Sudan. Anaemia is an accompaniment and independent risk factor for the development of cardiac dysfunction along with other complications. It is also responsible for 40-50% deaths in CRF patients. For this reason, the quick and accurate diagnosis of anaemia should help in decreasing the morbidity caused by CRF. The correction of anaemia, e.g. by the administration of iron supplements and/or erythropoietin, should help improving the general outcome of CRF. methods: Fifty patients with chronic renal failure, already diagnosed clinically and on laboratory basis were selected as a sample group. Another 50 healthy individuals not known to have renal disease were selected as a control group. 5 ml of venous blood was collected in lithium heparin container for iron and ferritin. Concentration of iron was measured by colorimetric method by using SPINREACT™ and serum ferritin by Turbilatex-Ferritin kit. The data obtained were analyzed by using statistical package for social science (SPSS) on programmed computer. Results: The mean ± SD of serum ferritin was calculated in patients and controls and it was found 72 μg/L ± 16.2 for patients and 96 μg/L ± 19.7 for controls the (p-value 0.000). Also the mean ± SD of serum iron was obtain from patients and controls and was found 41μg/dL ± 29.2 and 87 μg/dL ± 47.5 respectively with (p-value = 0.000). There were a weak negative correlation between serum iron and serum ferritin concentrations in patients and controls (R -0.161). Conclusion: The study concludes that serum iron and ferritin levels in CRF patients are significantly low in comparison to healthy controls.

Abstract
This paper reports on the observation of the sidereal large-scale anisotropy of cosmic rays using data collected by the ARGO-YBJ experiment over 5 years (2008–2012). This analysis extends previous work limited to the period from 2008 January to 2009 December, near the minimum of solar activity between cycles 23 and 24. With the new data sample, the period of solar cycle 24 from near minimum to maximum is investigated. A new method is used to improve the energy reconstruction, allowing us to cover a much wider energy range, from 4 to 520 TeV. Below 100 TeV, the anisotropy is dominated by two wide regions, the so-called “tail-in” and “loss-cone” features. At higher energies, a dramatic change of the morphology is confirmed. The yearly time dependence of the anisotropy is investigated. Finally, no noticeable variation of cosmic-ray anisotropy with solar activity is observed for a median energy of 7 TeV.
Cyclic Changes of the Sun’s Seismic Radius
Authors: Kosovichev Alexander , Rozelot Jean-Pierre 
Published: July 2018

Abstract
The questions asking whether the Sun shrinks with the solar activity and what causes this have been a subject of debate. Helioseismology provides a means to measure with high precision the radial displacement of subsurface layers, the so-called “seismic radius,” through the analysis of oscillation frequencies of surface gravity (f) modes. Here, we present results of a new analysis of 21 years of helioseismology data from two space missions, the Solar and Heliospheric Observatory and the Solar Dynamics Observatory, which allow us to resolve previous uncertainties and compare variations of the seismic radius in two solar cycles. After removing the f-mode frequency changes associated with the surface activity, we find that the mean seismic radius is reduced by 1–2 km during the solar maxima and that most significant variations of the solar radius occur beneath the visible surface of the Sun at a depth of about 5 ± 2 Mm, where the radius is reduced by 5–8 km. These variations can be interpreted as changes in the solar subsurface structure caused by the predominately vertical ∼10 kG magnetic field.

Published: July 2018

Abstract
PSR J2129−0429 is a 7.62 ms eclipsing millisecond pulsar (MSP) with a non-degenerate binary companion star that is likely in an early stage of the recycling process. It has one of the largest companion masses of a so-called “redback” (0.4 M
⊙) and has an unusually high surface magnetic field (1.6 × 109 G) for an MSP. We present here an X-ray and optical study of PSR J2129−0429 using new NuSTAR and LCOGT data of the system in addition to archival Swift and XMM-Newton data. Its X-ray light curve shows strong orbital variation from the intra-binary shock, about five times greater than is typical for other systems, and is clearly and persistently double-peaked. Its X-ray spectrum has a very hard power-law component (Γ = 1.1–1.2) which extends to ∼40 keV and exhibits an efficiency of up to a few percent in the X-ray band. The X-ray spectrum at the second peak of the light curve exhibits strong variability, while the spectrum of the first peak remains constant across observations. The hardness of the spectrum is suggestive of driven magnetic reconnection occurring at the shock. In addition, we observe the companion to be currently optically brightening after a multi-year period where it was dimming. The changes in color suggest that it has been continually cooling, implying that the companion is currently expanding.
Emotional responses to innovative Science teaching methods: Acquiring emotional data in a General Science teacher education class
Authors: Sanchez-Martin Jesus , Cañada-Cañada Florentina , Dávila-Acedo María Antonia 
Published: July 2018

The current work tries to inquiry how different teaching methods affect on the student’s emotional performance. The traditional questionnaire for data collection has been replaced by in-situ, on-line-assisted, survey. This instrument was continoulsy applied over the course of 17 General Science lessons. The experiment involved 120 prospective primary education teachers. Emotions to choose: rejection, boredom, satisfaction, surprise and the teaching methods involved were pure oral presentation, oral presentation with gamification, oral presentation with audiovisual support, oriented research, and hands-on activities. When the teaching method was changed to gamification or hands-on activities, the prospective teachers felt dynamic emotions, whereas they generally felt satisfaction or boredom (static emotions) with a traditional pure oral presentation. The students mainly identified the teaching method as being the most influential reason for having chosen their prevalent emotion, reflected in a dramatic increase in emotional performance when they were taught with innovative methods.

Qualidade e Equidade na Educação: A Hipótese da Curva de Kuznets Educacional
Authors: Neves Leonardo , Almeida Eduardo 
Published: July 2018

Este artigo objetivou compreender o relacionamento entre eficácia e qualidade educacionais, considerando, por base teórica a função-produção educacional. O trabalho consistiu na estimação de um painel de efeitos fixos, tendo o desvio-padrão das notas médias na Prova Brasil de 2007 e 2009 por variável dependente, controlada para um conjunto de variáveis explicativas socioeconômicas e educacionais, em médias municipais. A hipótese central testada foi a existência de uma relação em formato de U invertido entre a equidade e eficácia educacionais, seguindo a proposição da Curva de Kuznets, adaptada para mensurar a qualidade educacional. Os resultados indicaram que, embora não tenha se confirmado a hipótese da Curva de Kuznets, não foi verificada a existência de um trade-off entre desigualdade e qualidade educacionais.

Abstract. Future deep-sea mining for polymetallic nodules in abyssal plains will
negatively impact the benthic ecosystem, but it is largely unclear whether
this ecosystem will be able to recover from mining disturbance and if so, to
what extent and at what timescale. During the “DISturbance and
reCOLonization” (DISCOL) experiment, a total of 22 % of the seafloor
within a 10.8 km2 circular area of the nodule-rich seafloor in the Peru
Basin (SE Pacific) was ploughed in 1989 to bury nodules and mix the surface
sediment. This area was revisited 0.1, 0.5, 3, 7, and 26 years after the
disturbance to assess macrofauna, invertebrate megafauna and fish density and
diversity. We used this unique abyssal faunal time series to develop
carbon-based food web models for each point in the time series using the
linear inverse modeling approach for sediments subjected to two disturbance
levels: (1) outside the plough tracks; not directly disturbed by plough, but
probably suffered from additional sedimentation; and (2) inside the plough
tracks. Total faunal carbon stock was always higher outside plough tracks
compared with inside plough tracks. After 26 years, the carbon stock inside
the plough tracks was 54 % of the carbon stock outside plough tracks.
Deposit feeders were least affected by the disturbance, with modeled
respiration, external predation, and excretion rates being reduced by only
2.6 % inside plough tracks compared with outside plough tracks after
26 years. In contrast, the respiration rate of filter and suspension feeders
was 79.5 % lower in the plough tracks after 26 years. The “total system
throughput” (T..), i.e., the total sum of modeled carbon flows in the food web,
was higher throughout the time series outside plough tracks compared with
the corresponding inside plough tracks area and was lowest inside plough tracks
directly after the disturbance (8.63 × 10−3 ± 1.58 × 10−5 mmol C m−2 d−1). Even 26 years after the DISCOL
disturbance, the discrepancy of T.. between outside and inside plough
tracks was still 56 %. Hence, C cycling within the faunal compartments of
an abyssal plain ecosystem remains reduced 26 years after physical
disturbance, and a longer period is required for the system to recover from
such a small-scale sediment disturbance experiment.

Teaching students to teach patients: A theory-guided approach
Authors: Candela Lori , Piacentine Linda B. , Bobay Kathleen L. , Weiss Marianne E. 
Published: July 2018

Nurses in every setting provide patient teaching on a routine basis, often several times a day. Patient teaching skills are essential competencies to be developed during pre-licensure nursing education. While students learn what to teach for specific conditions, they often lack competence in how to teach in ways that individualize and optimize patient learning. The ultimate goal of patient teaching is to arm patients with the knowledge and skills, and the desire and confidence in their ability to reach their targeted health outcomes. We describe the creation of a theoretical framework to guide development of patient teaching skills. The framework, rooted in the contemporary health care values of patient-centered care, is a synthesis of four evidence-based approaches to patient teaching: patient engagement, motivational interviewing, adult learning theory, and teach-back method. Specific patient teaching skills, derived from each of the approaches, are applied within the context of discharge teaching, an important nursing practice linked to patient outcomes. This exemplar emphasizes the use of critical teaching process skills and targeted informational content. An online student learning module based on the theoretical framework and combined with simulation experiences provides the nurse educator with one strategy for use with nursing students. The theoretical framework has applicability for skill development during pre-licensure education and skill refinement for nurses in clinical practice.
El desarrollo histórico del conocimiento sobre las disoluciones y su relación con la Teoría Cinético-Molecular. Implicaciones didácticas
Authors: Blanco Ángel , Ruiz Lucía , Prieto Teresa 
Published: July 2018

El conocimiento sobre la naturaleza de la materia y sus propiedades tiene un papel importante en la educación científica. Los currículos en nuestro país incorporan la enseñanza de la teoría cinético-molecular, asumiendo que aspectos básicos de esta teoría pueden ser comprendidos, asimilados y aplicados por el alumnado de la educación secundaria obligatoria. Al mismo tiempo, se han ido acumulando evidencias que muestran que el aprendizaje de la naturaleza de la materia presenta grandes dificultades, y se reconoce que una proporción alta de estudiantes no consigue una comprensión adecuada de aspectos básicos de ella. En este artículo se intenta arrojar luz sobre esta cuestión recurriendo al análisis histórico. En primer lugar, se hace un recorrido a través de hitos importantes que han conducido a la construcción de la TCM. En segundo lugar, se analizan las teorías y modelos más utilizados a lo largo de la historia para explicar los fenómenos de disolución, relacionándolos con la TCM. Finalmente, se plantean algunas implicaciones didácticas.
