Published: March 2018

Aim

Patients admitted to General Medical Units (GMU) and Emergency Short Stay Units (ESSU) are often elderly with multiple comorbidities and the majority are considered to be at high risk of complications from influenza. The aim of this study was to assess the practice of including a pharmacist assessment of appropriateness and charting of influenza vaccination in a partnered pharmacist charting model in a GMU and ESSU.

Methods

As part of a partnered pharmacist charting model, the pharmacist assessed each patient for suitability of receiving the influenza vaccination at admission. If it was deemed appropriate by the pharmacist and medical officer, the pharmacist charted the influenza vaccination for administration as an inpatient and this was documented in the discharge summary to the general practitioner.

Results

There were 6595 patients admitted to the two units during the study period, of which 316 patients had partnered pharmacist charting. Among these, 52 patients were eligible for vaccination, of which 31 patients (59.6%) had their influenza vaccination charted by a pharmacist. Among the 6279 patients who had their medication charted by a medical officer only, there were no cases of influenza vaccination prescription (p < 0.01).

Conclusion

We identified that initiation of the influenza vaccination as part of the partnered pharmacist charting model is feasible and effective in increasing the rates of vaccination among ESSU and GMU patients.

Authors: López José J. , Orozco José G. , Vargas‐Peláez Claudia M.
Published: March 2018

Aim

To characterise systematic reviews and meta‐analyses on pharmacist care activities (PCAs) by means of bibliometric indicators.

Data sources

TheMEDLINE,EMBASEandLILACSdatabases were consulted.

Study selection

Articles describing/evaluatingPCAs in any setting (community, ambulatory or hospital) in which research design was a systematic review of the literature (SR) or a meta‐analysis (MA) were included.

Results

Of the 1180 publications retrieved from the search, 86 were included. The included papers were published between 1998 and 2014.SRs were the most frequent research design (84.9%). The most frequent settings were all‐care settings (n= 20, 23.3%), followed by community settings (n= 19, 22.1%). The most common target population included all types of population groups together (n= 53; 59.3%). None of theSR/MAs had a high quality level. The bibliometric analysis showed that theSR/MAs were carried out by an average of four authors (range 1–13) and 62.8% (54/86) of the analysedSR/MAs were written only by pharmacists. TheUSAand theUKwere the most frequent authors’ countries of origin. The 86SR/MAs were published in 49 journals, and the average impact factor was 1.172 (range: 5.827–0.109).

Conclusions

The results of this review evidenced the urgency of an agreement on aPCAclassification aiming at equating results among different studies. It is necessary to establish the minimum quality criteria for conducting studies onPC. Finally, the results showed the need for further research onPC(i) using qualitative methods and (ii) studying the paediatric population.

Published: March 2018

War zone deployment and posttraumatic stress disorder (PTSD) have been associated with morbidity and mortality decades later. Less is known about the associations between these variables and the early emergence of medical disorders in war zone veterans. This prospective study of 862 U.S. Army soldiers (n = 569 deployed; n = 293 nondeployed) examined: (a) associations between Iraq War deployment status (deployed vs. nondeployed) and new medical diagnoses that emerged within six months after return from Iraq among all participants; and (b) associations between combat severity and PTSD symptoms, and new postdeployment medical diagnoses that emerged within 12 months after return from Iraq within deployed participants. New medical diagnoses were abstracted from diagnostic codes associated with clinical outpatient visits recorded within the Department of Defense Standard Ambulatory Data Record database. Combat severity was measured with the Combat Experiences module of the Deployment Risk and Resilience Inventory, and postdeployment posttraumatic stress disorder symptom severity was measured using the PTSD Checklist–Civilian. Neither deployment nor combat severity was associated with new medical diagnoses. However, among deployed soldiers, more severe PTSD symptoms were associated with increased risk for a new medical disorder diagnosis; every 10‐point increase in PTSD symptoms increased odds of a new diagnosis by nearly 20% (odds ratio = 1.20). Results suggest that PTSD symptoms are associated with early morbidity in Iraq War veterans.
Quantitative Evaluation of the End‐to‐End Correlation Vector and of the Mean Square Displacement of the Molecules' Center in a Telechelic Polymer under Several Shear Rates Values
Authors: Manassero Carlo , Castellano Carlo
Published: March 2018

The results of molecular dynamics simulations of bead and spring models of telechelic polymers of general formula AB12A at melt‐like densities, under a shear rate, are presented. The A atoms, differing from the B ones, have self‐associate properties. In this paper, the quantitative correlation between the mean square displacement of the barycenter of the molecules and the correlation of the end‐to‐end vector with respect to the time is studied, depending on different values of the A–A interactions (included the one corresponding to the homopolymer, A = B) and of the shear deformation (included the zero, corresponding to the bulk conditions).
Social marketing: Using the health belief model to understand breast cancer protective behaviours among women
Authors: Tweneboah‐Koduah Ernest Yaw
Published: March 2018

The objective of the study was to apply the health belief model (HBM) to understand breast cancer protective behaviours recommended by implementers of social marketing intervention programmes among women in Ghana. A cross‐sectional survey using a 5‐point Likert scale questionnaire was used to collect data from 363 women. The data were analysed using descriptive statistics, factor analysis, multiple regression, and analysis of variance. The result shows that HBM was significant in explaining 68.9% of the variance in the breast cancer protective behaviours. The study found all the constructs of HBM (perceived susceptibility, perceived benefits, perceived barriers, self‐efficacy, and cues to action) with the exception of severity to have statistically significant relationship with the performance of breast cancer protective behaviours. Significant differences were found within respondents' age group and educational levels and the constructs of HBM regarding breast cancer protective behaviours.

Published: March 2018

Background

Involvement of risk‐organs (RO+) in Langerhans cell histiocytosis (LCH) and inadequate early response identifies patients at high risk for relapse and mortality requiring intensive salvage therapy including stem cell transplant, adding cost and toxicity. To mitigate this, we used a standard induction, augmented with metronomic etoposide, and prolonged maintenance—similarly augmented for RO+, and retrospectively analyzed its impact.

Procedure

LCH patients from 2009 through 2014 were included. Patients received standard vinblastine and prednisolone therapy weekly till week 25 for RO+. Single site (SS) and multisystem (MS) without risk organ involvement (RO−) received 3‐weekly pulses from week 13 till week 25. Maintenance was 3‐weekly vinblastine and 5‐day prednisolone pulses, daily 6‐mercaptopurine (60 mg/m2) and weekly methotrexate (15 mg/m2) for 18 and 9 months for RO+ and MSRO−, respectively. RO+ also received oral etoposide (50 mg/m2) for 21 of every 28‐day cycle for the first year.

Results

Fifty consecutive patients were analyzed. Median age was 36 months (4–189 months). SS, MSRO−, and RO+ were 29 (58%), 12 (24%), and nine (18%), respectively. Four were lost to follow‐up and excluded from further evaluation. On response evaluation at week 6, 24 (52%) had no active disease (NAD), 17 (37%) had AD‐better (where AD is active disease), and one (2%) had AD‐worse. In RO+, eight (66.6%) had AD‐better and three (25%) had NAD. Forty‐five patients had NAD by week 12. Three patients relapsed. With median follow‐up of 39 months (8–84), 5‐year event free survival was 85.6% (RO− and SS), and 100% for RO+. One patient's death in remission from unrelated causes resulted in overall survival of 97%.

Conclusions

RO+LCH receiving oral etoposide augmented induction and maintenance had early and durable responses. Prolonging maintenance lowered reactivation rates in RO+ and RO−LCH, resulting in excellent survival.
Current methods for the prediction of T‐cell epitopes
Authors: Kar Prattusha , Ruiz‐Perez Lanie , Arooj Mahreen , Mancera Ricardo L.
Published: March 2018

T‐cell epitopes are specific peptide sequences derived from foreign or own proteins that can initiate an immune response and which are recognized by specific T‐cells when displayed on the surface of other cells. The prediction of T‐cell epitopes is of particular interest in vaccine design, disease prevention and the development of immunotherapeutics. There are two principal categories of predictive methods: peptide‐sequence based and peptide‐structure‐based. Sequence‐based methods make use of various approaches to identify likely immunogenic amino acid sequences, such as sequence motifs, decision trees, partial least squares (PLS), quantitative matrices (QM), artificial neural networks (ANN), hidden Markov models (HMM), and support vector machines (SVM). Structure‐based methods are more diverse in nature and involve approaches such as quantitative structure‐activity relationships (QSAR), molecular modelling, molecular docking and molecular dynamics simulations (MD). This review highlights the key features of all of these approaches, provides some key examples of their application, and compares and contrasts the most important methods currently in use.
Influence of Oxygen on the Resistivity of Co‐Sputtered Transparent AZO Films
Authors: Novák Petr , Kozák Tomáš , Šutta Pavol , Kolega Michal , Bláhová Olga
Published: March 2018

In the present work co‐sputtering from ceramic and metallic targets is used to reduce the oxygen content in aluminium doped zinc oxide. Films with thickness between 200 and 220 nm are sputtered at 100 and 250 °C and investigated by X‐ray diffraction, energy dispersive spectroscopy, and Hall measurements. It is found that reducing of the incorporated oxygen in the film leads to higher carrier concentration, mainly due to better effective activation of Al donors. Higher temperatures result in better carrier mobility due to improving the crystallinity. The best resistivity of 1.4 × 10−3 Ω cm of the highly transparent film prepared at 100 °C is achieved. A larger oxygen reduction leads to lower resistivity, but also results in the significant deterioration of transmittances.
Spectroscopic Ellipsometry and Microstructure Characterization of Photochromic Oxygen‐Containing Yttrium Hydride Thin Films
Authors: Montero José , Karazhanov Smagul Z.
Published: March 2018

Oxygen‐containing yttrium hydride, YHx:Oy, is an inorganic phothochromic material which exhibits promising features for its application in smart windows, ophthalmic lenses, and many more. In the present work the optical properties of photochromic and non‐photochromic YHx:Oy thin films prepared by magnetron sputtering are studied by variable angle ellipsometry and spectrophotometry. These include the study of the complex refractive index, the transmittance, and luminous transmittance, as well as the reflectance of a selection of samples of diverse structural properties obtained under different deposition conditions. In the case of the photochromic YHx:Oy thin films, the refractive index in the near infrared and visible regions is found similar to the one corresponding to yttrium oxide, Y2O3. However, the YHx:Oy films exhibit a smaller band gap and hence higher absorption in the near ultraviolet than Y2O3. The photodarkening potential of the films are also quantified and characterized by the study and modeling of their optical properties before and after illumination. Our results show that photochromic YHx:Oy films, with a luminous transmittance above 80 % in the clear state, can reduce its transparency up to a 30% after 1 h illumination at 1 Sun.

Population ageing and future labour market challenges
Authors: Kühn Stefan , Milasi Santo , Yoon Sheena
Published: March 2018

The chapter provides an overview of the labour market challenges posed by a fast ageing global population. It shows that, while the ratio of potential retirees per person participating in the labour market is expected to increase markedly by 2030, the average age of those in the labour force is also set to gradually increase over the same period. These dynamics pose the dual challenge of keeping retirees out of poverty while promoting decent work outcomes for the growing share of older workers in the labour force. The chapter concludes by highlighting a number of policy options to tackle these challenges.
Heavy charged scalars from $$ c\overline{s} $$ fusion: a generic search strategy applied to a 3HDM with U(1) × U(1) family symmetry
Authors: Camargo-Molina José Eliel , Mandal Tanumoy , Pasechnik Roman , Wessén Jonas
Published: March 2018

Abstract

We describe a class of three Higgs doublet models (3HDMs) with a softly broken U(1) × U(1) family symmetry that enforces a Cabibbo-like quark mixing while forbidding tree-level flavour changing neutral currents. The hierarchy in the observed quark masses is partly explained by a softer hierarchy in the vacuum expectation values of the three Higgs doublets. As a consequence, the physical scalar spectrum contains a Standard Model (SM) like Higgs boson h
125 while exotic scalars couple the strongest to the second quark family, leading to rather unconventional discovery channels that could be probed at the Large Hadron Collider. In particular, we describe a search strategy for the lightest charged Higgs boson H
±, through the process

$$ c\overline{s}\to {H}^{+}\to {W}^{+}{h}_{125} $$

, using a multivariate analysis that leads to an excellent discriminatory power against the SM background. Although the analysis is applied to the proposed class of 3HDMs, we employ a model-independent formulation such that it can be applied to any other model with the same discovery channel.
Essence and definition by abstraction
Authors: Hale Bob
Published: March 2018

We may define words or concepts, and we may also, as Aristotle and others have thought, define the things for which words stand and of which concepts are concepts. Definitions of words or concepts may be explicit or implicit, and may seek to report preexisting synonymies, as Quine put it, but they may instead be wholly or partly stipulative. Definition by abstraction, of which Hume’s principle is a much discussed example, seek to define a term-forming operator, such as the number operator, by fixing the truth-conditions of identity-statements featuring terms formed by means of that operator. Such definitions are a species of implicit definition. They are typically at least partly stipulative. Definitions of things, or real definitions, are, by contrast, typically conceived as true or false statements about the nature or essence of their definienda, and so not stipulative. There thus appears to be an obvious and head-on clash between taking Hume’s principle as an implicit and at least partly stipultative definition of the number operator and taking it as a real definition, stating the nature or essence of cardinal numbers. This paper argues that this apparent tension can be resolved, and that resolving it sheds light on part of the epistemology or essence and necessity, showing how some of our knowledge of essence and necessity can be a priori.
Maximizing the short circuit current of organic solar cells by partial decoupling of electrical and optical properties
Authors: Qarony Wayesh , Hossain Mohammad I. , Jovanov Vladislav , Knipp Dietmar , Tsang Yuen Hong
Published: March 2018

The partial decoupling of electronic and optical properties of organic solar cells allows for realizing solar cells with increased short circuit current and energy conversion efficiency. The proposed device consists of an organic solar cell conformally prepared on the surface of an array of single and double textured pyramids. The device geometry allows for increasing the optical thickness of the organic solar cell, while the electrical thickness is equal to the nominal thickness of the solar cell. By increasing the optical thickness of the solar cell, the short circuit current is distinctly increased. The quantum efficiency and short circuit current are determined using finite-difference time-domain simulations of the 3D solar cell structure. The influence of different solar cell designs on the quantum efficiency and short circuit current is discussed and optimal device dimensions are proposed.

Authors: Morton Hamer Melinda J. , Reed Paul L. , Greulich Jane D. , Beadling Charles W.
Published: March 2018

US Africa Command’s Disaster Preparedness Program (DPP), implemented by the Center for Disaster and Humanitarian Assistance Medicine, partnered with US Government agencies and international organizations to promote stability and security on the African continent by engaging with African Partner Nations’ (PN) civil and military authorities to improve disaster management capabilities. From 2008 to 2015, DPP conducted disaster preparedness and response programming with 17 PNs. DPP held a series of engagements with each, including workshops, strategic planning, developing preparedness and response plans, tabletop exercises, and prioritizing disaster management capability gaps identified through the engagements. DPP partners collected data for each PN to further capacity building efforts. Thus far, 9 countries have completed military pandemic plans, 10 have developed national pandemic influenza plans, 9 have developed military support to civil authorities plans, and 11 have developed disaster management strategic work plans. There have been 20 national exercises conducted since 2009. DPP was cited as key in implementation of Ebola response plans in PNs, facilitated development of disaster management agencies in DPP PNs, and trained nearly 800 individuals. DPP enhanced PNs’ ability to prepare and respond to crises, fostering relationships between international agencies, and improving civil-military coordination through both national and regional capacity building.

Published: March 2018

The goal of this research was to identify, summarize, and evaluate pediatric disaster preparedness resources in the United States and to identify areas that need improvement or further development. Using standard literature, gray literature and website reviews, relevant resources were identified and the 50 most relevant resources were studied in depth. Each resource was given a grade of A, B, or C based on content, format, quality, and thoroughness. These resources were divided into 3 categories: (1) hospital resources, (2) school resources, and (3) training/education resources. Half of the 50 resources (25) were given a grade of A, indicating the highest level of quality and thoroughness, with pertinent information presented in a clear format. Sixteen of the resources were given a rating of B, while 9 of the resources were given a rating of C. Over 60% of the resources did not contain culturally sensitive information and more than 60% of the resources did not contain preparedness information for children with disabilities. Resources specific to hospitals and schools were limited in number and quality available, while training/education resources were widely available. In addition, 60% of resources were not specific to schools, children’s hospitals, or to certain occupations (ie, nurses, doctors, teachers, principals). Based on these results, gaps in cultural sensitivity were identified and limitations in resources for children with disabilities and for schools and hospitals currently exist. All these areas require further development in the field of pediatric disaster preparedness (Disaster Med Public Health Preparedness. 2019;13:330–337)

A SPEAR ‘LIKE A BALL’: A NOTE ON SOPHOCLES, FR. 781
Authors: Corthals Bob
Published: March 2018

Etymologicum Magnum s.v. ἔγχος (313, 3):

ὁ δὲ Σοφοκλῆς τὴν σφαῖραν ἔγχος κέκληκεν, οἶον ‘τὸ δ’ ἔγχος ἐν ποσὶ κυλίνδεται’.

Sophocles has called a ball egkhos (‘spear’), as in ‘and the egkhos rolls to (someone's) feet’.

The quoted fragment is generally assigned to Sophocles' Nausicaa (or Plyntriai). This suggestion dates back to nineteenth-century scholarship, is found in the editions of Pearson and Radt, and has been accepted by LSJ (s.v. ἔγχος II. ‘of Nausicaa's ball’). Certainly, the Nausicaa will have included a version of the famous scene in which the Phaeacian princess and her maidens enjoy a game of ball. Pearson thought it probable that the words are part of Odysseus' speech at the court of Alcinous (cf. Od. 7.290), in which he would have recalled Nausicaa's misdirected cast (cf. 6.115). The feet, on this view, are Odysseus' own. According to Welcker, Odysseus calls the ball an ἔγχος, ‘because it reached him like a missile’. This is awkward: an ἔγχος is properly a thrusting spear and, at any rate, the quality of being thrown does not enter into the immediate image, as the fragment's object is said to reach someone's feet rolling.
Setting up a parathyroid multidisciplinary team meeting: one year's experience, outcomes and learning points
Authors: Hancox S H , Sinnott J D , Kirkland P , Lipscomb D , Owens E , Howlett D C
Published: March 2018

Objective:

A parathyroid multidisciplinary team meeting was set up at East Sussex Healthcare Trust, from November 2014 to November 2015, in order to improve and streamline services for patients with parathyroid pathology.

Methods:

Data were collected on all new referrals for hyperparathyroidism, and on the outcomes for each patient discussed at the meeting, including the number of operations and management outcomes. A survey was sent out to the members of the multidisciplinary team meeting to determine their perception of its effectiveness.

Results:

Seventy-nine new referrals were discussed throughout the year; 43 per cent were recommended for surgery, 41 per cent had a trial of conservative or medical management before re-discussion, and 16 per cent required further imaging. Ninety-two per cent of patients underwent an ultrasound, single-photon emission computed tomography/computed tomography or nuclear medicine (sestamibi) scan prior to the meeting. All ultrasound scans were performed by a consultant radiologist.

Conclusion:

The multidisciplinary team meeting has been successful, with perceived benefits for patients, improved imaging evaluation and efficiency of referral pathways, leading to more appropriate patient management.
Russia and the Liberal World Order
Authors: Clunan Anne L.
Published: March 2018

While Russian leaders are clearly dissatisfied with the United States and the European Union, they are not inherently opposed to a liberal world order. The question of Russia's desire to change a liberal international order hangs on the type of liberalism embedded in that order. Despite some calls from within for it to create a new, post-liberal order premised on conservative nationalism and geopolitics, Russia is unlikely to fare well in such a world.
A Post-Western Europe: Strange Identities in a Less Liberal World Order
Authors: Wæver Ole
Published: March 2018

Debates on “rising powers” and a possible end to the liberal international order mostly focus on two kinds of actors: the hegemon (the United States), privileged by the power distribution of yesteryear, and rising powers (notably China). Europe's curious position brings to light some intriguing dynamics of the emerging world order—nuances needed to capture a more differentiated future. This essay traces the threats and opportunities to Europe presented by the emerging order in four domains. In terms of overall power (polarity) and economics, far-reaching change registers but is rarely designated as threatening. In contrast, change regarding values (human rights and democracy especially) triggers more alarm. Finally, in the domain of institutions, change elicited a relative lack of concern prior to 2016, but worries have grown since then. For Europe, peaceful change primarily demands that rising powers rearticulate rather than confront classical Western values because, in contrast to the United States, there is little sense of loss in Europe in relation to the global structures of power and economics.
Interdisciplinarity, History and Cultural Encounters
Authors: Larsen Svend Erik
Published: March 2018

Interdisciplinarity has entered the agenda of researchers, teachers and policy makers and will remain there in the future. This does not mean that interdisciplinarity is understood the same way, let alone is appreciated everywhere. Researchers are challenged by increasingly complex problems in culture, nature and society beyond disciplinary boundaries; higher education has to cater to a volatile job market where known disciplines no longer define their own niches in terms of topics or practices for their candidates; and decision makers are confronted with challenges that do not respect ideologies of political parties and reports based on mainstream knowledge. In this context, interdisciplinarity is an ongoing re-consideration of the creation, the communication and the application of knowledge uniting the perspectives of research, teaching and decision making. While most discussions on interdisciplinarity focus on its theoretical and methodological complexity in an exclusively contemporary perspective, this article will discuss interdisciplinarity in a historical perspective as central to European history of knowledge as well as in an intercultural perspective.*
A Neuropsychological Profile for Agenesis of the Corpus Callosum? Cognitive, Academic, Executive, Social, and Behavioral Functioning in School-Age Children
Authors: Siffredi Vanessa , Anderson Vicki , McIlroy Alissandra , Wood Amanda G. , Leventer Richard J. , Spencer-Smith Megan M.
Published: March 2018

Objectives:Agenesis of the corpus callosum (AgCC), characterized by developmental absence of the corpus callosum, is one of the most common congenital brain malformations. To date, there are limited data on the neuropsychological consequences of AgCC and factors that modulate different outcomes, especially in children. This study aimed to describe general intellectual, academic, executive, social and behavioral functioning in a cohort of school-aged children presenting for clinical services to a hospital and diagnosed with AgCC. The influences of age, social risk and neurological factors were examined.Methods:Twenty-eight school-aged children (8 to 17 years) diagnosed with AgCC completed tests of general intelligence (IQ) and academic functioning. Executive, social and behavioral functioning in daily life, and social risk, were estimated from parent and teacher rated questionnaires. MRI findings reviewed by a pediatric neurologist confirmed diagnosis and identified brain characteristics. Clinical details including the presence of epilepsy and diagnosed genetic condition were obtained from medical records.Results:In our cohort, ~50% of children experienced general intellectual, academic, executive, social and/or behavioral difficulties and ~20% were functioning at a level comparable to typically developing children. Social risk was important for understanding variability in neuropsychological outcomes. Brain anomalies and complete AgCC were associated with lower mathematics performance and poorer executive functioning.Conclusions: This is the first comprehensive report of general intellectual, academic, executive social and behavioral consequences of AgCC in school-aged children. The findings have important clinical implications, suggesting that support to families and targeted intervention could promote positive neuropsychological functioning in children with AgCC who come to clinical attention.

A cross-sectional survey of nutrition labelling use and its associated factors on parents of school students in Shanghai, China
Authors: Ma Jianhong , Zhu Zhenxin , Chen Xiao , Guo Yan , Zhang Huansheng , Zhang Yuyan , Zang Jiajie
Published: March 2018

Objective

To understand parents’ knowledge and use of nutrition labelling and to explore its associated factors.

Design

Cross-sectional survey.

Setting

Two schools providing a nine-year educational programme in Putuo District, Shanghai, China, were selected for the study. Information was included on demographic data and knowledge of the Chinese Food Pagoda.

Subjects

Students and their parents (n 1770) participated in a questionnaire survey.

Results

Of questionnaires, 1766 were completed (response rate 99·8 %). Utilization rate of nutrition labelling was 19·3 %. Among 624 parents knowing nutrition labelling, 22·1 % understood all the information included, 70·7 % understood it partially and 7·2 % could not understand it at all. Use of nutrition labelling by parents was related to the following factors (OR; 95 % CI): high educational level of parent (1·465; 1·165, 1·841), parent’s knowledge of the Chinese Food Pagoda (1·333; 1·053, 1·688), parent’s consumption of top three snacks which are unhealthy (1·065; 1·023, 1·109), parent’s assumption that nutrition labelling would affect their choice of food (1·522; 1·131, 2·048), student’s willingness to learn about labels (1·449; 1·093, 1·920) and student’s knowledge and use of labels (2·214; 1·951, 2·513).

Conclusions

Parents’ knowledge and use of nutrition labelling are still at a lower level, and some information included in the nutrition labels is not understood by parents. The forms of the existing nutrition labelling need to be continuously improved to facilitate their understanding and usefulness. It is necessary to establish nutrition projects focusing on education and use of nutrition labels which help parents and their children make the right choices in selecting foods.
Tc-trend and terrestrial planet formation: The case of Zeta Reticuli
Authors: Adibekyano V. , Delgado-Mena E. , Santos N. C. , Sousa S. G. , Figueira P.
Published: March 2018

Some studies suggested that the chemical abundance trend with the condensation temperature, Tc, is a signature of rocky planet formation. Very recently, a strong Tc trend was reported in ζ2 Ret relative to its companion (ζ1 Ret) and was explained by the presence of a debris disk around ζ2 Ret. We re-evaluated the presence and variability of the Tc trend in this system with a goal to understand the impact of the presence of the debris disk on a star. Our results confirm the reported abundance difference between ζ2 Ret and ζ1 Ret and its dependence on the Tc. However, we also found that the Tc trends depend on the individual spectrum used. We conclude that for the ζ Reticuli system, for example, nonphysical factors can be at the root of the Tc trends for the case of individual spectra. For more details see Adibekyan et al. (2016b).
The white dwarf mass-radius relation with Gaia, Hubble and FUSE
Authors: Joyce Simon R. G. , Barstow Martin A. , Casewell Sarah L. , Holberg Jay B. , Bond Howard E.
Published: March 2018

White dwarfs are becoming useful tools for many areas of astronomy. They can be used as accurate chronometers over Gyr timescales. They are also clues to the history of star formation in our galaxy. Many of these studies require accurate estimates of the mass of the white dwarf. The theoretical mass-radius relation is often invoked to provide these mass estimates. While the theoretical mass-radius relation is well developed, observational tests of this relation show a much larger scatter in the results than expected. High precision observational tests to confirm this relation are required. Gaia is providing distance measurements which will remove one of the main source of uncertainty affecting most previous observations. We combine Gaia distances with spectra from the Hubble and FUSE satelites to make precise tests of the white dwarf mass-radius relation.

Published: March 2018

The extended observational program for study of cataclysmic variables is realized in Sternberg Astronomical Institute during the last years. A few telescopes of Crimean Observational Station equipped with a different devices, — UBV photometer and two CCD camera, are used for observations. Among the close binary systems (CBS), cataclysmic variables are the most interesting objects because of the outburst activity and variety of their observational features. They could serve a good laboratory for study of physical processes in CBS. GAIA provides astronomers with a new ample opportunity for investigation of cataclysmic variables. Though the relative faintness of detected objects it is still possible to carry out a high accuracy ground-based observations with our equipment. Obtained ground-based data permit us to confirm classification of detected CV-candidates, to determine the physical characteristics with a sample of new cods and improve the current understanding of their nature.

We present an in-depth study of metal-poor stars, based high resolution spectra combined with newly released astrometric data from Gaia, with special attention to observational uncertainties. The results are compared to those of other studies, including Gaia benchmark stars. Chemical evolution models are discussed, highlighting few puzzles that are still affecting our understanding of stellar nucleosynthesis and of the evolution of our Galaxy.

We examined the O-C diagrams of eclipsing binary systems and selected these exhibiting cyclic shape, either sinusoidal or quasi sinusoidal. Assuming these variations being due to the Light Time Travel effect (LTE), we estimated the parameters of companions with the Monte Carlo method. As a result, we identified nearly two dozen of eclipsing systems that might have companions with a minimum mass larger than that of a neutron star. Their masses fall into the range between 1.7 and 34 solar masses. This sample of triples with high mass companions can be confirmed with the help of observations gathered by Gaia: parallaxes and astrometric measurements.

Thanks to their point-like structure and to their lack of significant proper motion, quasars represent the ideal objects for modeling quasi-inertial directions in space. For that reason the present primary conventional reference frame, the ICRF-2, is constructed from the set of the celestial coordinates of a sample of extragalactic objects, whose the very large majority are quasars. Thus any newly discovered quasar must be considered as a potential future ideal astrometric marker. Therefore compiling all the recorded quasars at a given epoch looks as a useful task. This constitutes the aim of the LQAC (Large Quasar Astrometric Catalogue). We present here the contents of the future release of this catalogue quoted as the LQAC-4, insisting on the related strategy of compilation. Preliminary results concerning the cross-identification with the Gaia DR1 catalogue are emphasized
Searching for planets around eclipsing binary stars using timing method: NSVS 14256825

Published: March 2018

We present four new mid eclipse times and an updated O-C diagram of the short period eclipsing binary NSVS14256825. The new data follow the (O-C) trend and its model proposed in Nasiroglu et al. (2017). The (O-C) diagram shows quasi-periodic variations that can be explained with the presence of a brown-dwarf in a quasi-circular circumbinary orbit.

A spread of lifebuilding elements, such as carbon, nitrogen, and oxygen in the Galactic discs is yet not well investigated. In this study, we use spectra from the UVES spectrograph (Gaia-ESO survey ) and the VUES spectograph (SPFOT-PLATO survey) and determine the carbon, nitrogen, and oxygen abundances in FGK stars using the same technique. For some of our target stars the Gaia space observatory has already presented accurate distances, thus we overview the first results of radial and vertical CNO abundance distributions in the Galactic thin and thick disc populations.

Published: March 2018

We use the TGAS proper motions and parallaxes as well as published and new radial velocities to study the dynamics of nearby moving groups. In particular we try to determine their age using backtracing of the individual members to a common origin. We find that the current data, probably the radial velocities, do not allow to reach a successful conclusion.
Understanding Li enhancement in K giants and role of accurate parallaxes
Authors: singh Raghubar , Reddy B. E.
Published: March 2018

Our recent studies based on a large sample of K giants with Hipparcos parallaxes and spectroscopic analysis resulted more than a dozen new Li-rich K giants including few super Li-rich ones. Most of the Li-rich K giants including the new ones appear to occur at the luminosity bump in the HR diagram. However, one can’t rule out the possibility of overlap with the clump region where core He-burning K giants reside post He-flash at the tip of RGB. It is important to distinguish field K giants of clump from the bump region in the HR diagram to understand clues for Li production in K giants. In this poster, we explore whether GAIA parallaxes improve to disentangle clump from bump region, more precisely.

Published: March 2018

Since 2015, scientific activities at the Terskol Observatory have been aimed at optical follow-up of stellar objects and asteroids detected within the framework of the Gaia mission. Two years of successful research have yielded new data and findings in this field. Photometric observations of Gaia transients allowed us to reveal physical characteristics of a good few of them. Moreover, we detected positions of dozens of asteroids which were reported by the GBOT group. In this paper, some results obtained from observations of transients Gaia16bkf, Gaia16bkn, Gaia17asz and newly detected asteroids are presented.
On-sky verification of the 6-h periodic basic angle variations of the Gaia satellite

A Basic Angle (BA) of 106.5° separates the view directions of Gaia's two fields of view (FoV). A precise determination of the BA variations (BAV) is essential to guarantee a correct reconstruction of the global astrometric sphere, as residual systematic errors would result in, e.g., a bias in the parallaxes of the final Gaia catalog. The Basic Angle Monitoring (BAM) device, which provides a reliable and accurate estimation of BAV, shows that there exists a ~1 mas amplitude, 6-h period BA oscillation. It's essential to verify to what extent this signal is caused by real BAV, or is at least in part an effect of the BAM device itself. Here, we propose an astrometric on-sky approach to re-determine the 6-h periodic BAV. The results of this experiment, which treated a full day (17 Oct 2016) of Gaia astrometric data, recover a value for the 6-h oscillation of 1.856±0.857 mas. This is consistent, within the errors, with the BAM finding for that day.
Dynamical effects of the spiral arms on the velocity distribution of disc stars

Published: March 2018

Nearby disc stars in Gaia DR1 (TGAS) and RAVE DR5 show a bimodal velocity distribution in the metal-rich region (characterized by the Hercules stream) and mono-modal velocity distribution in the metal-poor region. We investigate the origin of this [Fe/H] dependence of the local velocity distribution by using 2D test particle simulations. We found that this [Fe/H] dependence can be well reproduced if we assume fast rotating bar models with Ωbar ≃ 52 km s−1 kpc−1. A possible explanation for this result is that the metal-rich, relatively young stars are more likely to be affected by bar's outer Lindblad resonance due to their relatively cold kinematics. We also found that slowly rotating bar models with Ωbar ≃ 39 km s−1 kpc−1 can not reproduce the observed data. Interestingly, when we additionally consider spiral arms, some models can reproduce the observed velocity distribution even when the bar is slowly rotating.
Open Cluster Dynamics via Fundamental Plane
Authors: Lin Chien-Cheng , Pang Xiao-Ying
Published: March 2018

Open clusters (OCs) are important objects for stellar dynamics studies. The short survival timescale of OCs makes them closely related to the formation of Galactic field stars. We motivate to investigate the dynamical evolution of OCs on the aspect of internal effect and the external influence. Firstly, we make use of the known OC catalog to obtain OCs masses, effective radii. Additionally, we estimate OCs kinematics properties by OC members cross-matched with radial velocity and metallicity from SDSSIV/APOGEE2. We then establish the fundamental plane of OCs based on the radial velocity dispersion, the effective radius, and average surface brightness. The deviation of the fundamental plane from the Virial Plane, so called the tilt, and the r.m.s. dispersion of OCs around the average plane are used to indicate the dynamical status of OCs. Parameters of the fitted plane will vary with cluster age and distance.

Current Galactic surveys, including the Gaia mission, rely on the efficiency of the spectral analysis techniques to provide precise and accurate spectral information (i.e. effective temperature, surface gravity, metallicity, and chemical abundances) in the shortest computational time. In this work, we present a new package to preform complete spectral analyses based on the spectral synthesis technique (Tsantaki et al. 2017, submitted). We focus on deriving atmospheric parameters for FGK-type stars using both high and medium resolution (GIRAFFE) spectra. This method is implemented on the Gaia-ESO benchmark stars to confirm its validity, achieving similar accuracy for the two resolution setups.
Precise CCD positions of Triton in 2014-2016 from the Gaia DR1

Published: March 2018

755 CCD observations during the years 2014-2016 have been reduced to derive the precise positions of Triton, the first satellite of Neptune. The observations were made by the 1 m telescope at Yunnan Observatory over 15 nights during the years 2014-2016. The theoretical position of Triton was retrieved from the Jet Propulsion Laboratory Horizons system. Our results show that when the newest Gaia catalogue (Gaia DR1) is referred to the mean O-Cs (observed minus computed) residuals are about 0.042 and -0.006 arcsec, the dispersions are 0.012 and 0.012 arcsec in right ascension and declination, respectively. The dispersions are improved very significantly when the Gaia DR1 is referred to. However, the agreement in right ascension is not so good as that in declination, the reason might come from the uncertainty of planet ephemeris. More observations are needed to confirm this.

Published: March 2018

Knowledge of the spin and shape parameters of the asteroids is very important for understanding of the conditions during the creation of our planetary system and formation of asteroid populations. The main belt asteroid and Flora family member 967 Helionape was observed during five apparitions. The observations were made at the Bulgarian National Astronomical Observatory (BNAO) Rozhen, since March 2006 to March 2016. Lihtcurve inversion method (Kaasalainen et al. (2001)), applied on 12 relative lightcurves obtained at various geometric conditions of the asteroid, reveals the spin vector, the sense of rotation and the preliminary shape model of the asteroid. Our aim is to contribute in increasing the set of asteroids with known spin and shape parameters. This could be done with dense lightcurves, obtained during small number of apparitions, in combination with sparse data produced by photometric asteroid surveys such as the Gaia satellite (Hanush (2011)).
