A Light-curve Analysis of Gamma-Ray Nova V959 Mon: Distance and White Dwarf Mass
Authors: Hachisu Izumi , Kato Mariko 
Published: May 2018

Abstract
V959 Mon is a nova detected in gamma-rays. It was discovered optically about 50 days after the gamma-ray detection owing to its proximity to the Sun. The nova’s speed class is unknown because of the lack of the earlier half of its optical light curve and a short supersoft X-ray phase due to eclipse by the disk rim. Using the universal decline law and time-stretching method, we analyzed the data on V959 Mon and obtained nova parameters. We estimated the distance modulus in the V band to be (m − M)
V
= 13.15 ± 0.3 for the reddening of E(B − V) = 0.38 ± 0.01 by directly comparing it with novae of a similar type—LV Vul, V1668 Cyg, IV Cep, and V1065 Cen. The distance to V959 Mon is 2.5 ± 0.5 kpc. If we assume that the early phase of the light curve of V959 Mon is the same as that of time-stretched light curves of LV Vul, our model fitting of the light curve suggests that the white dwarf (WD) mass is 0.9–1.15 M
⊙, which is consistent with a neon nova identification. At the time of gamma-ray detection the photosphere of the nova envelope extends to 5–8 R
⊙ (about two or three times the binary separation) and the wind mass-loss rate is

yr−1. The period of hard X-ray emission is consistent with the time of appearance of the companion star from the nova envelope. The short supersoft X-ray turnoff time is consistent with the epoch when the WD photosphere shrank to behind the rising disk rim, which occurred 500 days before nuclear burning turned off.

AIM: To construct new fetal biometric charts and equations for some fetal biometric parameters for women between 12th and 41st weeks living in Ismailia and Port Said Governorates in Egypt.MATERIAL AND METHODS: This cross-sectional study was carried out on 656 Egyptian women (from Ismailia and Port Said governorates) with an uncomplicated pregnancy, and all were sure of their dates. The selected group was between the 12th and 41st weeks of gestation, recruited from the district general hospital in Ismailia and Port Said to measure ultrasonographically biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL), then for each measurement separate regression models were fitted to estimate both the mean and the Standard deviation at each gestational age.RESULTS: New Egyptian charts were reported for BPD, HC, AC, and FL. Reference equations for the dating of pregnancy were presented. The mean of the previous measurements at 12th and 41st weeks were as follows: (23.37, 98.72), (83.05, 336.12), (67.85, 332.57) and (12.50, 74.92) respectively.CONCLUSION: New fetal biometric charts and regression equations for pregnant women living in Port Said & Ismailia governorates in Egypt.

Folded tubular photometer for atmospheric measurements of NO2 and NO
Authors: Birks John W. , Andersen Peter C. , Williford Craig J. , Turnipseed Andrew A. , Strunk Stanley E. , Ennis Christine A. , Mattson Erick 
Published: May 2018

Abstract. We describe and characterize a modular folded tubular photometer
for making direct measurements of the concentrations of nitrogen dioxide
(NO2) and specify how this method could be extended to measure other
pollutants such as sulfur dioxide (SO2), ozone (O3), and black
carbon particulate matter. Direct absorbance measurements using this
photometer can be made across the spectral range from the ultraviolet (UV) to
the near infrared. The absorbance cell makes use of modular components
(tubular detection cells and mirror cubes) that allow construction of path
lengths of up to 2 m or more while maintaining low cell volumes. The long
path lengths and low cell volumes enable sensitive detection of ambient air
pollutants down to low part-per-billion levels for gas species and aerosol
extinctions down to 1 Mm−1, corresponding to
∼ 0.1 µg m−3 for black carbon particulates. Pressure
equalization throughout the stages of the absorbance measurement is shown to
be critical to accurate measurements of analyte concentrations. The present
paper describes the application of this photometer to direct measurements of
nitrogen dioxide (NO2) and the incorporation of design features that
also enable measurement of nitric oxide (NO) in the same instrument.
Excellent agreement for ambient measurements along an urban roadside was
found for both NO2 and NO measured by the folded tubular photometer
compared to existing standard techniques. Compared to commonly used methods
for measurements of NOx species, the advantages of this approach include
(1) an absolute quantification for NO2 based on the Beer–Lambert
law, thereby greatly reducing the frequency at which calibrations are
required; (2) the direct measurement of NO2 concentration without
prior conversion to NO as is required for the commonly used chemiluminescence
method; (3) the use of modular components that allow construction of
absorbance detection cells of varying lengths for extending the dynamic range
of concentrations that can be measured; (4) a more economical instrument than
other currently available direct measurement techniques for NO2;
and (5) the potential for simultaneous detection of additional species such
as SO2, O3, and black carbon in the same instrument. In
contrast to other commercially available direct NO2 measurements,
such as cavity-attenuated phase-shift spectroscopy (CAPS), the folded tubular photometer also measures NO simultaneously in the same apparatus by
quantitatively converting NO to NO2 with ozone, which is then
detected by direct absorbance.
Ocean-Liner Cutaways, Diagrams, and Composites: Technical Illustration as Mass Aesthetic in Popular Mechanics and The Illustrated London News
Authors: Ross Shawna 
Published: May 2018

ABSTRACT
This article analyzes the visual rhetoric of ocean-liner illustrations that appeared in mass periodicals in the late-nineteenth and early-twentieth centuries. Cutaways, diagrams, and composite images of ocean liners created an innovative visual style that fused data structures with pop aesthetics, combining pedagogy of media literacy with the pleasures of voyeurism and vicarious voyaging. Illustrations of the Queen Mary and the sinking of the Titanic are emphasized to show how mass periodicals constructed imagined, impossible scenes of ocean travel that humanized abstract, large-scale technological changes and crises of modernity, thereby rendering them comprehensible to a mass readership.
The American Colonies: Paris's Chicago Tribune and Paris-American Identity
Authors: Cannon Nissa Ren 
Published: May 2018

ABSTRACT
By the late 1920s, Paris was home to 40,000 expatriate Americans and 400,000 visitors. While these Americans received much attention in subsequent decades, the newspapers catering to this community have received less scrutiny. This article considers how the Paris edition of the Chicago Tribune narrated a shared experience of life abroad for American residents, drew a common map of Paris, and codified community values, even as it revealed distinctions about residents. I argue that the paper transported patriotic affiliation overseas while representing and reinforcing a version of American identity that was inherently transnational.

ABSTRACT
The purpose of this retrospective study was to report the outcomes of 19 dogs and 1 cat undergoing reverse saphenous conduit flap between 1999 and 2016. Reverse saphenous conduit flap was used to treat traumatic wounds and wounds resulting from tumor excision in the hind limb; the majority of cases had medial shearing injuries. All animals had complete flap survival. In five animals (20%), minor donor site dehiscence occurred, which did not require surgery. Other postoperative complications included signs of severe venous congestion in one dog. Reverse saphenous conduit flap is a useful technique to repair skin defects of the distal hind limb.

Published: May 2018

Background: Patient safety is the cornerstone for better quality health care and nursing education. There is limited evidence about how patient safety is addressed in healthcare professional curricula and how organizations develop safe practitioners.Aim: To assess the practices and perception of nursing students regarding the safety of critically ill patients.Materials and methods: Participants of this descriptive correlation exploratory study were 100 nursing students conveniently from the students enrolled in Critical Care Nursing course during academic year 2013-2014 in faculty of nursing, Alexandria University. The study was conducted in the critical care units affiliated to Alexandria Main University Hospital namely (Unit I, Unit III, and Triage). The first tool was Critical Care Practices of Safety Measures Observational Checklist and the second tool was Students’ Unsafe Clinical Practices Perception questionnaire.Results: It was found that 49% of the nursing students had poor perception regarding their unsatisfactory clinical performance. In addition, 55% of the nursing students have poor perception regarding their poor documentation. Furthermore, 44% of them have poor perception regarding lack of clinical educators’ role competency.Conclusions: Nursing students’ perception was poor regarding their clinical performance, cognitive performance and critical thinking skills and documentation. In addition, nursing students reported that they have poor perception regarding nurse educators’ role competency. Therefore, nursing curriculum should incorporate concepts and principles that guide nursing students in developing caring, safe, competent and professional behavior and should be developed for the nursing students based on the WHO patient safety topics which will focus on patient safety.

Published: May 2018

<p>El objetivo de este trabajo fue analizar la Escala de Valoración de la Carga del entrenamiento Técnico-Táctico (Coque, 2009) y su relación con parámetros de carga interna. En la actualidad, se plantea un modelo de planificación que se caracteriza por la preocupación de mejorar la interpretación que el sujeto hace de lo que sucede a su alrededor durante la competición (Martín Acero, Seirul-lo Vargas, Lago Peñas, y Novoa Lalín, 2013), para así modificar la respuesta y a su vez, el esquema motriz. El estudio contó con las jugadoras del equipo de Liga Femenina del Club Baloncesto Conquero, compuesto por 12 jugadoras, con edades comprendidas entre 17 y 33 años (M = 21.91; SD = 4.81). Los datos fueron recogidos durante los dos últimos meses de competición que se corresponden con los meses de febrero y marzo de 2016. Para obtener los datos necesarios se utilizaron la escala de valoración subjetiva de la carga de entrenamiento Técnico-Táctico (Coque, 2009), la percepción subjetiva del esfuerzo (Borg, 1970; 1998; Borg &amp; Kaijser,2006) y la calidad de la recuperación (Kentta &amp; Hassmen, 1998). Los resultados mostraron que sólo la densidad del entrenamiento es el único marcador que podría explicar, de forma importante (91.4%), el esfuerzo percibido de las jugadoras. Según los datos obtenidos la percepción subjetiva del esfuerzo podría ser utilizada para la monitorización del entrenamiento en cuanto a la complejidad técnico-táctica del mismo.</p>

Authors: Rodriguez Jacqueline A. , Dieker Lisa A. 
Published: May 2018

ABSTRACT
For refugee children with disabilities, international agencies provide largely humanitarian assistance, including education. However, the obstacles associated with refugee existence can impede progress in the movement towards educating children with disabilities in inclusive settings. This literature review summarizes the historical progression towards inclusive education for the United Nations Relief and Works Agency for Palestine Refugees (UNRWA). Historical perspectives of inclusion are presented for this region and discussed in relation to policy and potential implications for teaching practice. Catalysts for change in the region, and specifically within UNRWA, are described, and actors involved in improving education for all children are presented. Finally, the emergence of inclusive education within UNRWA is described in the context of policy and programming change.
Effects of a Tailored Incredible Years Teacher Classroom Management Programme on On-Task Behaviour of School Children with ADHD in Addis Ababa
Authors: Mohammed Feruz 
Published: May 2018

AbstractAttention-Deficit/Hyperactivity Disorder (ADHD) is a persistent pattern of behaviours characterized by inattention, hyperactivity and impulsivity. This study evaluates the effects of a tailored Incredible Years Teacher Classroom Management (IYTCM) programme aimed to improve participating children's on-task behaviour in a group of 6 to 10 year old children with ADHD in Addis Ababa, Ethiopia. The effectiveness of the IYTCM programme has been extensively examined for children with conduct disorder and/or behaviour and emotional issues, but not specifically with children with ADHD. In the present study, the effects of the IYTCM were examined on individual children with ADHD symptoms. Nine children identified with ADHD symptoms on the basis of teacher and parent reports of behaviour and nine normative comparison children were also selected from the same classrooms. Ten teachers received the tailored IYTCM-ADHD training for about 36 hours. A single-subject design was implemented to record the behaviour changes over time: at baseline, during teacher training with the IYTCM-ADHD programme, and at both immediate and long-term follow-ups. In addition to visual analysis, a non-parametric test was used to examine the magnitude of effect in each child. The result of the study indicated that the on-task behaviour of participating children with ADHD increased by the conclusion of the study ranging from 46% to 100%. Visual analysis also indicated that the children's behaviour was maintained during the follow-up phases. The pre- and post-intervention analyses of children with ADHD showed a significant effect of the intervention on each child. In light of the findings, limitations and implications for future research are discussed.
Physics of Bubble‐Propelled Microrockets
Authors: Gallino Giacomo , Gallaire François , Lauga Eric , Michelin Sebastien 
Published: May 2018

AbstractA popular method to induce synthetic propulsion at the microscale is to use the forces created by surface‐produced gas bubbles inside the asymmetric body of a catalytic swimmer (referred to in the literature as microrocket). Gas bubbles nucleate and grow within the swimmer and migrate toward one of its openings due to asymmetric geometric confinement, generating a net hydrodynamic force which propels the device. Here, numerical simulations are used to develop a joint chemical (diffusive) and hydrodynamic (Stokes) analysis of the bubble growth within a conical catalytic microrocket and of the associated bubble and microrocket motion. With this computational model, the bubble dynamics are solved for over one bubble cycle ranging from its nucleation to its exiting the conical rocket, and the propulsion characteristics are identified as a function of all design parameters (geometry and chemical activity of the motor, surface tension, physicochemical constants). The results suggest that hydrodynamics and chemistry partially decouple in the motion of the bubbles, with hydrodynamics determining the distance travelled by the microrocket over each cycle while chemistry sets the bubble ejection frequency. This numerical model allows for the identification of an optimal microrocket shape and size for which the distance travelled per cycle duration is maximized.
Cholesteric Liquid Crystal Shells as Enabling Material for Information‐Rich Design and Architecture

Published: May 2018

AbstractThe responsive and dynamic character of liquid crystals (LCs), arising from their ability to self‐organize into long‐range ordered structures while maintaining fluidity, has given them a role as key enabling materials in the information technology that surrounds us today. Ongoing research hints at future LC‐based technologies of entirely different types, for instance by taking advantage of the peculiar behavior of cholesteric liquid crystals (CLCs) subject to curvature. Spherical shells of CLC reflect light omnidirectionally with specific polarization and wavelength, tunable from the UV to the infrared (IR) range, with complex patterns arising when many of them are brought together. Here, these properties are analyzed and explained, and future application opportunities from an interdisciplinary standpoint are discussed. By incorporating arrangements of CLC shells in smart facades or vehicle coatings, or in objects of high value subject to counterfeiting, game‐changing future uses might arise in fields spanning information security, design, and architecture. The focus here is on the challenges of a digitized and information‐rich future society where humans increasingly rely on technology and share their space with autonomous vehicles, drones, and robots.
Cobalt‐Catalyzed C(sp3)−H Functionalization Reactions
Authors: Yoshino Tatsuhiko , Matsunaga Shigeki 
Published: May 2018

AbstractC−H functionalization reactions hold great potential for the streamlined synthesis of complex molecules and are currently a “hot” topic in organic synthesis. Among the various transition metals that have been used, cobalt has recently attracted increased attention as a catalyst for C−H functionalization reactions, owing to its ready availability and high reactivity. Although a number of cobalt‐catalyzed C(sp2)−H functionalization reactions have been reported to date, C(sp3)−H functionalization reactions remain challenging. This Focus Review summarizes recent progress in cobalt‐catalyzed C(sp3)−H functionalization reactions that involve C−H activation to form organometallic intermediates.
A Copper‐ and Phosphine‐Free Nickel(II)‐Catalyzed Method for C−H Bond Alkynylation of Benzothiazoles and Related Azoles
Authors: Patel Ulhas N. , Punji Benudhar 
Published: May 2018

AbstractA phosphine‐free nickel(II)‐catalyzed method for the C(2)−H bond alkynylation of (benzo)thiazoles, (benz)imidazoles, and oxazoles is described. Well‐defined and air‐stable (Phen)NiCl2 catalyst efficiently catalyzes the coupling of diverse azoles with alkynyl bromides without the use of a copper co‐catalyst, and the method tolerates synthetically important functional groups. Preliminary mechanistic studies on this NiII‐catalyzed alkynylation emphasize the homogeneous nature of the catalyst, and rule out a radical manifold for the reaction. The synthetic utility of this Ni‐catalyzed method is demonstrated by further functionalizing the alkynylated benzothiazoles to 3‐methyl‐2‐(alkynyl)benzo[d]thiazolium salts that are known DNA cleaving agents.
From Fission to Censorship: 18 Months on the Road to the Bomb
Authors: Reed B. Cameron 
Published: May 2018

AbstractDespite longstanding speculation concerning the harnessing of atomic energy, the prospect of doing so was not a foregone conclusion upon the discovery of fission in late 1938. Many aspects of the new phenomenon such as secondary neutrons, cross‐sections, and energetics had to be investigated before the feasibility of nuclear reactors or explosives could be established. Here, experimental and theoretical developments in the 18 months following the discovery of fission are summarized; these develeopments laid the groundwork for wartime nuclear programs.
