Effective implementation of ISO 50001 energy management system
Authors: Mkhaimer Leen G , Arafeh Mazen , Sakhrieh Ahmad H
Published: March 2017

Organizations are spending large amounts of money on their energy consumption. The scarcity of energy resources, along with their price volatility, has become a major concern for all industries. Consequently, the need for managing and conserving energy has recently gained larger attention. A good management always pursues savings opportunities with minimum investments; hence, establishing an energy management system can provide the right approach to detect opportunities and sustain improvements. This article proposes the Lean Six Sigma energy management model (LSS_EnMS) based on the framework of International Organization for Standardization (ISO) 50001 for energy management, supported by the LSS approach define, measure, analyse, improve and control (DMAIC). The LSS_EnMS model applies the DMAIC approach to the energy management process in companies and incorporates the needed tools to define system requirements, analyse energy data, establish a systematic approach to identify energy opportunities and finally to guarantee sustainable system improvements. The model has shown the compatibility of Six Sigma approach with the ISO 50001 framework and has provided guidelines for effective system implementation. A prominent pharmaceutical company in Jordan was taken as a case study to show the significance of this model, and how this approach can lead to valuable and advantageous results in terms of real case application.
Meeting Report: The Fourth Artificial Pancreas Workshop: Testing and Adoption of Current and Emerging Technologies
Authors: Ginsberg Barry H. , Klonoff David C. , Crabtree Vincent P.
Published: March 2017

On July 6 and 7, 2016 the Fourth Artificial Pancreas Workshop: Testing and Adoption of Current and Emerging Technologies was held on the National Institutes of Health (NIH) Campus at the Lister Hill Auditorium. The meeting was sponsored by a group of governmental organizations and NGOs, listed in Appendix A. This was a very timely meeting as the artificial pancreas appears to be growing from academic studies to commercial projects. The first artificial pancreas may be marketed within 12 months and a few may be approved within 24 months. The NIH, the FDA, the JDRF, Helmsley Trust, Diabetes Technology Society, and other agencies, funders, and organizations have been strongly supportive of advancing artificial pancreas technology and usability, and thus the proceedings from this conference should be of exceptional interest to the diabetes technology community.
Regendering care or undoing gendered binaries of parenting in contemporary UK society?
Authors: Locke Abigail
Published: March 2017

Boyer, Dermott, James and MacLeavy discuss the rise of fathers in primary caregiving positions within the United Kingdom following the recessions from 2008 to 2009 and 2011 to 2012 and outline a number of key questions. In this commentary, I consider the aims of their piece, both within contemporary parenting culture and the negotiation of gendered binaries of care. I note that a more intersectional understanding of the decisions that families are making with regard to combining work and childcare is timely.
Stay-at-home fathers on the wane – In comes daddy day! Changing practices of fathering in German-speaking countries
Authors: Schwiter Karin , Baumgarten Diana
Published: March 2017

Our commentary brings Boyer et al.’s (2017) argument of a ‘regendering of care’ through men’s growing engagement as caregivers into a dialogue with scholarship from German-speaking countries. This literature supports Boyer et al.’s claim of a connection between labour market opportunities and stay-at-home fatherhood. However, the research from our language context also suggests that fathers who are not gainfully employed do not necessarily become primary caregivers. Furthermore, the number of stay-at-home fathers is shrinking rather than growing. In light of these findings, we suggest shifting the discussion from stay-at-home fathers to fathers as part-time workers and part-time carers. This is where we identify the potential for a subtle revolution that bears the promise of far more wide-ranging changes in the gendering of care.
Actualizing marine policy engagement
Authors: Brewer Jennifer
Published: March 2017

Authors Winder and Le Heron (2017) call on geographers to engage in marine policy venues associated with the Blue Economy agenda. This commentary suggests a pragmatic approach, drawing on our human–environment and spatial traditions and bridging positivist and critical constructivist epistemologies. Biophysical attributes of ocean environments create diffuse publics. Examples from fisheries and marine planning illustrate how geographers can lend expertise in scalar and socio-spatial complexity.
Through the Looking Glass: The Queer Narcissism of Selfies
Authors: Goldberg Greg
Published: March 2017

A number of scholars have recently argued that the selfie needs to be understood outside of the discourse of narcissism. Rather than leaving this discourse behind, this article focuses on the “hype” of selfies as narcissistic in order to identify and ultimately trouble the political unconscious of this diagnosis, and to ask, what is the problem of narcissism such that it can serve as a means of devaluing, and what kind of politics might we find in the behaviors, proclivities, or attributes identified as narcissistic? The article argues that the problem of narcissism is less an exaggerated focus on the self than it is a failure of responsibility for oneself, and/or an insufficient concern for the well-being of others to whom the narcissist ought to be responsible. Drawing from the antisocial thesis in queer theory, the article argues that this normative investment in responsible subjectivity is motivated, rather ironically, by a desire to annihilate difference. As a “solution” to this desire, the article offers queer theorist Leo Bersani’s notion of “impersonal narcissism,” which it understands in relation to the queerness of the myth from which narcissism takes its name. In short, the article does not aim to evaluate empirically attributions of selfie narcissism—whether to confirm or falsify—but rather to problematize the diagnosis of narcissism as rooted in a normative project that works to produce responsible subjects, and to suggest that this project is compromised by a queer indifference to difference, as critics fear.

Published: March 2017

Enhancers frequently contain multiple binding sites for the same transcription factor. These homotypic binding sites often exhibit synergy, whereby the transcriptional output from two or more binding sites is greater than the sum of the contributions of the individual binding sites alone. Although this phenomenon is frequently observed, the mechanistic basis for homotypic binding site synergy is poorly understood. Here, we identify a bona fide cardiac-specific Prkaa2 enhancer that is synergistically activated by homotypic MEF2 binding sites. We show that two MEF2 sites in the enhancer function cooperatively due to bridging of the MEF2C-bound sites by the SAP domain-containing co-activator protein myocardin, and we show that paired sites buffer the enhancer from integration site-dependent effects on transcription in vivo. Paired MEF2 sites are prevalent in cardiac enhancers, suggesting that this might be a common mechanism underlying synergy in the control of cardiac gene expression in vivo.
Using synthetic biology to explore principles of development
Authors: Davies Jamie
Published: March 2017

Developmental biology is mainly analytical: researchers study embryos, suggest hypotheses and test them through experimental perturbation. From the results of many experiments, the community distils the principles thought to underlie embryogenesis. Verifying these principles, however, is a challenge. One promising approach is to use synthetic biology techniques to engineer simple genetic or cellular systems that follow these principles and to see whether they perform as expected. As I review here, this approach has already been used to test ideas of patterning, differentiation and morphogenesis. It is also being applied to evo-devo studies to explore alternative mechanisms of development and ‘roads not taken’ by natural evolution.
Escape path complexity and its context dependency in Pacific blue-eyes (Pseudomugil signifer)
Authors: Herbert-Read J. E. , Ward A. J. W. , Sumpter D. J. T. , Mann R. P.
Published: March 2017

The escape paths prey animals take following a predatory attack appear to be highly unpredictable - a property that has been described as ‘protean behaviour’. Here we present a method of quantifying the escape paths of individual animals using a path complexity approach. When individual fish (Pseudomugil signifer) were attacked, we found that a fish's movement path rapidly increased in complexity following the attack. This path complexity remained elevated (indicating a more unpredictable path) for a sustained period (at least 10 seconds) after the attack. The complexity of the path was context dependent; paths were more complex when attacks were made closer to the fish, suggesting that these responses are tailored to the perceived level of threat. We separated out the components of speed and turning rate changes to determine which of these components contributed to the overall increase in path complexity following an attack. We found that both speed and turning rate measures contributed similarly to an individual's path complexity in absolute terms. Overall, our work highlights the context dependent escape responses that animals use to avoid predators and also provides a method for quantifying the escape paths of animals.
Crystal structure of U2 snRNP SF3b components: Hsh49p in complex with Cus1p-binding domain
Authors: van Roon Anne-Marie M. , Oubridge Chris , Obayashi Eiji , Sposito Benedetta , Newman Andrew J. , Séraphin Bertrand , Nagai Kiyoshi
Published: March 2017

Spliceosomal proteins Hsh49p and Cus1p are components of SF3b, which together with SF3a, Msl1p/Lea1p, Sm proteins, and U2 snRNA, form U2 snRNP, which plays a crucial role in pre-mRNA splicing. Hsh49p, comprising two RRMs, forms a heterodimer with Cus1p. We determined the crystal structures of Saccharomyces cerevisiae full-length Hsh49p as well as its RRM1 in complex with a minimal binding region of Cus1p (residues 290–368). The structures show that the Cus1 fragment binds to the α-helical surface of Hsh49p RRM1, opposite the four-stranded β-sheet, leaving the canonical RNA-binding surface available to bind RNA. Hsh49p binds the 5′ end region of U2 snRNA via RRM1. Its affinity is increased in complex with Cus1(290-368)p, partly because an extended RNA-binding surface forms across the protein–protein interface. The Hsh49p RRM1–Cus1(290-368)p structure fits well into cryo-EM density of the Bact spliceosome, corroborating the biological relevance of our crystal structure.
Routine Use of Contrast Swallow After Total Gastrectomy and Esophagectomy: Is it Justified?
Authors: El-Sourani Nader , Bruns Helge , Troja Achim , Raab Hans-Rudolf , Antolovic Dalibor
Published: March 2017

Background: After gastrectomy or esophagectomy, esophagogastrostomy and esophagojejunostomy are commonly used for reconstruction. Water-soluble contrast swallow is often used as a routine screening to exclude anastomotic leakage during the first postoperative week. In this retrospective study, the sensitivity and specificity of oral water-soluble contrast swallow for the detection of anastomotic leakage and its clinical symptoms were analysed.

Material/Methods: Records of 104 consecutive total gastrectomies and distal esophagectomies were analysed. In all cases, upper gastrointestinal contrast swallow with the use of a water-soluble contrast agent was performed on the 5th postoperative day. Extravasation of the contrast agent was defined as anastomotic leakage. When anastomotic insufficiency was suspected but no extravasation was present, a computed tomography (CT) scan and upper endoscopy were performed.

Results: Oral contrast swallow detected 7 anastomotic leaks. Based on CT-scans and upper endoscopy, the true number of anastomotic leakage was 15. The findings of the oral contrast swallow were falsely positive in 4 and falsely negative in 12 patients, respectively. The sensitivity and specificity of the oral contrast swallow was 20% and 96%, respectively.

Conclusions: Routine radiological contrast swallow following total gastrectomy or distal esophagectomy cannot be recommended. When symptoms of anastomotic leakage are present, a CT-scan and endoscopy are currently the methods of choice.
DNACPR (‘do not attempt cardiopulmonary resuscitation’) orders in patients with a fractured neck of femur who lack capacity
Authors: Hill DS , Nazar L , Freudmann M
Published: March 2017

Nationally, half of all deaths occur in hospital, with 94% having a ‘do not attempt cardiopulmonary resuscitation’ (DNACPR) notice in place at the time of death. Recent court rulings have raised the profile of practices surrounding DNACPR orders where patients lack capacity. Failure to consult with those close to the patient in relation to DNACPR decisions is a breach of the right to respect for private and family life under article 8 of the Human Rights Act.

A report from 2016 found that those close to the patient were not consulted before one out of every five DNACPR orders are placed. We advocate addressing the issue of resuscitation in patients with a fractured neck of femur who are approaching the end of their lives. Where the patient lacks capacity, there is a legal duty to consult with those close to the patient where it is practicable and appropriate to do so. There must be a convincing and well evidenced reason to proceed without consultation, and the orthopaedic surgeon should exercise extreme caution before doing so.
Radical prostatectomy for locally advanced and metastatic prostate cancer
Authors: Veeratterapillay R , Goonewardene SS , Barclay J , Persad R , Bach C
Published: March 2017

The management of advanced prostate cancer remains challenging. Traditionally, radical prostatectomy was discouraged in patients with locally advanced or node positive disease owing to the increased complication rate and treatment related morbidity. However, technical advances and refinements in surgical techniques have enabled the outcomes for patients with high risk prostate cancer to be improved. More recently, the concept of cytoreductive prostatectomy has been described where surgery (often Combined with an extended lymph node dissection) is performed in the setting of metastatic disease. Indirect evidence suggests an advantage using the cytoreductive approach. Hypothetical explanations for this observed benefit include decreased tumour burden, immune modulation, improved response to secondary treatment and avoidance of secondary complications attributable to local tumour growth. Nevertheless, prospective trials are required to investigate this further.

O tempo de resposta do ataque inicial a incêndios florestais nos espaços mais sensíveis de Portugal: o exemplo prático da serra da Lousã
Authors: Félix Fernando , Lourenço Luciano
Published: March 2017

A ocorrência de incêndios florestais necessita da conjugação de condições atmosféricas favoráveis, vegetação combustível e uma fonte de ignição. Reunidas estas três condições, os incêndios florestais começam, normalmente, por ser pequenas fogueiras. Depois, a reposta do ataque inicial determina, quase sempre, as características que os incêndios acabam por assumir, pelo que o tempo necessário para essa resposta deverá estar em consonância com as características intrínsecas a cada um dos espaços florestais, para assim se mitigarem as consequências e reduzirem as dimensões das áreas ardidas. https://doi.org/10.14195/1647-7723_24_14

Vom sanktionierten Pariastaat zum Joint-Venture der Welt. Aspekte der ökonomischen Dynamik Myanmars
Authors: Mahnkopf Cordula Meyer
Published: March 2017

Due to its internationally accompanied opening policies, Myanmar’s present economic situation is unique even on a global scale. The present contribution addresses the question if the ranking of Mynamar on position 150 of the UN Human Development Index indeed reflects the country’s economic situation. The paper investigates the historical developments in Myanmar after 1948, the Western sanctions regime after 1988, the integration into ASEAN, the present framework for ‘doing business’, and the dynamics of foreign capital and domestic labor conditions. The paper concludes that the years of political isolation and repression still inhibit the country’s fast economic progress. The future welfare of this politically disrupted country so rich in natural resources does not only depend on its government and its ascending civil society, but also on FDI by foreign companies.
“You Don’t Wear a Fur in Summer”: Kang Youwei’s Impartial Words on Republicanism (1917) and the Fate of Chinese Democracy
Authors: Brusadelli Federico
Published: March 2017

This article aims to discuss Kang Youwei’s 康有為 (1858–1927) position on democracy and republicanism in China through the analysis of two major works of his late production: Datongshu 大同書 (Book of Great Concord, drafted in 1902, but only published posthumously in 1935) and Gonghe Pingyi 共和評議 (Impartial Words on Republicanism, 1917), seemingly presenting two opposite views on the same issue. Whereas in his most “esoteric” production, represented by the Datongshu, Kang prophesied the spread of democracy on a global scale (China included), he remained loyal to the prospect of a Chinese constitutional monarchy in his public appearances after 1911 – the same he had abortively sponsored during the Hundred Days’ Reform of 1898. In 1917, playing an active role in the short and somehow farcical restoration of the last Manchu emperor on the throne orchestrated by warlord Zhang Xun, Kang published Impartial Words on Republicanism, a significant essay through which he intended to explain the apparent contradiction between his republican utopia on the one hand and his “imperial” project on the other. Through the translation and discussion of some extracts from the two aforementioned works, I will try to shed more light on Kang’s complex views on the issue and on the ambivalence of his political and theoretical agenda. Finally, I will also suggest that Kang’s reflections may appear to have been successively echoed by later intellectuals in the debate on the possibility and nature of a “Chinese democracy”.
Se servir de la fiction comme guide: l’exemple des « romans de carrière » chinois contemporains
Authors: Gonseth Morgane
Published: March 2017

This paper focuses on « workplace novels », a literary genre which emerged in the 2000s in Mainland China, as well as on the various discourses surrounding these works by editors, publicists, and scholars. Even though some novels of this category have enjoyed a significant popular and commercial success, the attention they attract in the academic circles seems out of proportion when compared with the actual production of the genre. Moreover, the advertisement and academic discourses concerning these texts have proven to be highly congruent, even stereotyped, as they all describe workplace novels as the career guides of the young urban white-collar workers who are supposed to read them. This congruence is all the more surprising when considering that the information and advice that these novels are supposed to offer do not seem specific nor concrete enough to be applied in a real situation. This paper proposes to address this ambivalence, as well as its origins and implications.
Le commentaire de Tankuang sur l’Eveil à la Foi dans le Grand Véhicule: la probable influence de Wonhyo
Authors: Guerra-Glarner Monika
Published: March 2017

Tankuang was a Chinese monk active during the eighth century. His texts were found in Dunhuang at the beginning of the twentieth century, and only then included in the Taishō canon. Tankuang wrote several commentaries on numerous Mahāyāna sutras, and two of these texts are commentaries on the Dasheng qixin lun. This paper focuses on the influence of two Korean monks, Wonch’uk and Wonhyo, on Tankuang’s commentaries. Whereas it seems clear that Tankuang was affiliated to the Ximing lineage of Wonch’uk, there is no such evidence concerning the influence of Wonhyo. But it appears that Tankuang is taking over some of the concepts introduced by Wonhyo, and there are some clear cases of textual and doctrinal evidence of this influence that I will present in this paper.

Tracing Galaxy Evolution by Their Present-Day Luminosity Function
Authors: Tempel E.
Published: March 2017

Galaxy luminosity functions are derived for different morphological types and various colors of galaxies, to trace the evolutionary effects which a priori should be different for void and supercluster galaxies. We also analyse how the galaxy group content changes in the large-scale environment. One of the principal results is the conclusion that the evolution of spiral galaxies is almost independent of the global environment. Meanwhile, the luminosity function of elliptical galaxies depends strongly on the environment. This shows that the global environmental density is an important factor in the formation of elliptical galaxies. The results of the present study clearly show that, except the local/group environment, the global (supercluster-void) environment plays an important role in the formation and evolution of galaxies.
Stark Broadening of Carbon and Oxygen Lines in Hot DQ White Dwarf Stars: Recent Results and Applications
Authors: Dufour P. , Nessib N. Ben , Sahal-Bréchot S. , Dimitrijević M. S.
Published: March 2017

White dwarf stars are traditionally found to have surface compositions made primarily of hydrogen or helium. However, a new family has recently been uncovered, the so-called hot DQ white dwarfs, which have surface compositions dominated by carbon and oxygen with little or no trace of hydrogen and helium (Dufour et al. 2007, 2008, 2010). Deriving precise atmospheric parameters for these objects (such as the effective temperature and the surface gravity) requires detailed modeling of spectral line profiles. Stark broadening parameters are of crucial importance in that context. We present preliminary results from our new generation of model atmospheres including the latest Stark broadening calculations for C II lines and discuss the implications as well as future work that remains to be done.

The obtained data will be included in the STARK-B database, which is a part of the Virtual Atomic and Molecular Data Center.
Statistical Analysis of Langmuir Waves Associated with Type III Radio Bursts: II. Simulation and Interpretation of the Wave Energy Distributions
Authors: Maksimović M. , Vidojević S. , Zaslavsky A.
Published: March 2017

We have modeled electrostatic Langmuir waves by an electric field, consisting of superposition of Gaussian wave packets with several probability distributions of amplitudes and with several Poisson distributions of wave packets. The outcome of the model is that the WIND satellite observations, especially in the low frequency domain (the WAVES experiment), do not allow to conclude whether the input wave amplitude distributions are closer to the log-normal than to the Pearson type I or uniform. The average number of wave packets in 1 s is found to be between 0.1 and 50. Therefore, there is a clear need to measure Langmuir wave energy distributions directly at the waveform level, not a posteriori in the spectral domain. This is planned to be implemented on the RPW (Radio and Plasma Wave Analyzer) instrument in the Solar Orbiter mission.
High Energy Emission of Symbiotic Recurrent Novae: RS Oph and V407 Cyg
Authors: Hernanz M. , Tatischeff V.
Published: March 2017

Recurrent novae occurring in symbiotic binaries are candidate sources of high energy photons, reaching GeV energies. Such emission is a consequence of particle acceleration leading to pion production. the shock between matter ejected by the white dwarf, undergoing a nova explosion, and the wind from the red giant companion are responsible for such a process, which mimics a supernova remnant but with much smaller energetic output and much shorter time scales. Inverse Compton can also be responsible for high energy emission. Recent examples are V407 Cyg, detected by Fermi, and RS Oph, which unfortunately exploded in 2006, before Fermi was launched.

Contribution of the Electron Scattering Process to the Broad Hα Wings
Authors: Sekeráš M. , Skopal A.
Published: March 2017

We modeled the extended wings of the OVI 1032, 1038 Å resonance lines and He II 1640 Å emission line in the spectra of Z And, AG Dra and V1016 Cyg by the electron scattering process. By this way we determined the electron temperature and the electron optical depth of the layer of electrons, through which the line photons are transferred in the direction of the observer. We derived an empirical relationship between the emission measure of the symbiotic nebula and the electron optical depth. This relationship allows us to distinguish the flux contribution in the broad Hα wings, which is due to the electron scattering and that produced by the Hα transition in the moving hydrogen plasma. For example, subtracting the electron scattering contribution from the Hα line profile leads to a reduction in the mass-loss rate by approximately 15 %.
On the Symbiotic X-Ray Binary Nature of the Star CGCS 5926
Authors: Masetti N. , Munari U. , Henden A. A. , Page K. L. , Osborne J. P. , Starrfield S.
Published: March 2017

We report on multiwavelength (from X-ray to optical) follow up observations of a carbon star CGCS 5926, motivated by the fact that it is positionally coincident with a faint X-ray source of the ROSAT catalog, thus suggesting its possible symbiotic X-ray binary (SyXB) nature. Our optical spectroscopy confirms that this is a carbon star of type C(6,2). This allows us to infer for CGCS 5926 a distance of ~5 kpc. BVRCIC photometry of the star shows variability of ~0.3 mag with a periodicity of 151 days, which we interpret as due to radial pulsations. the source is not detected with the Swift satellite in X-rays down to a 0.3-10 keV luminosity of ~3 × 1032 erg s−1. This nondetection is apparently in contrast with the ROSAT data; however, the present information does not rule out that CGCS 5926 can be a SyXB. This will be settled by more sensitive observations at high energies.
High-Resolution Spectroscopy of the Hydrogen-Deficient Binary υ Sgr
Authors: Kipper Tõnu , Klochkova Valentina G.
Published: March 2017

The high resolution spectra of hydrogen-deficient binary υ Sgr are analyzed. The atmospheric parameters are Teff = 12300±200 K, log g = 2:5±0:5 and ξt = 5 - 15 kms−1 depending on the element. For Fe II ξt = 9:3 ± 0:3 kms−1. Iron is slightly underabundant (-0.2 dex). Nitrogen is overabundant with [N/Fe]ͬ ≈ 1.0, carbon and oxygen are underabundant with [C/Fe] ≈ -1.6 and [O/Fe] ≈ -1.1. The s-process elements Y, Zr and Ba are overabundant about 0.5 dex. Quite large number of emission lines, both permitted and forbidden, originating from low excitation levels of neutral and ionized metals, are identified. Radial velocities of these emission lines indicate that an accretion disk in the system is present.

A project devoted to astrometric and photometric observations of asteroids at the Molėtai Observatory is described. One of its most important results is the discovery of the asteroid 2010 BT3 belonging to the Amor group of the near-Earth objects. The results of astrometric and photometric observations of the asteroid are presented. The brightness variations of the asteroid are found to be about 0.2 mag in R. The orbit of the asteroid was computed from 96 observations. This orbit, combined with the apparent brightness, gives the absolute magnitude 21.34 mag and the diameter between 160 m and 360 m, taking albedos of S-type and C-type asteroids, respectively.

Virtual Observatory facilities allow users to make a fast and correct cross-matching of objects from various surveys. They yield multi-color photometry data (color indices) on registered objects and make it possible to determine stellar parameters. A method of catalogue cross-matching, as well as its application to various areas in the sky and preliminary results of stellar parameterization, are discussed in the paper. We also make a critical analysis of modern stellar spectral atlases.
Large Astronomical Surveys, Catalogs and Databases
Authors: Mickaelian A. M.
Published: March 2017

We review the status of all-sky and large astronomical surveys and their catalogued data over the whole range of electromagnetic spectrum, from gamma-ray to radio, such as ROSAT in X-ray, GALEX in UV, SDSS and several POSS1/2 based catalogs (APM, MAPS, USNO, GSC) in optical, 2MASS and WISE in NIR, IRAS and AKARI in MIR/FIR, NVSS and FIRST in radio range and others. Present astronomical archives contain billions of objects, Galactic as well as extragalactic, and the vast amount of data in them permit new studies and discoveries. Cross-correlations result in revealing new objects and new samples. Very often, dozens of thousands of sources hide a few very interesting ones that are needed to be discovered by comparison of various physical characteristics. Most of the modern databases currently provide VO access to the stored information. This permits not only open access but also fast analysis and managing of these data.

Authors: Vereshchagin S. V. , Chupina N. V.
Published: March 2017

The plate collection of the Zvenigorod 40-cm Carl Zeiss astrograph, obtained in 1972-2003, contains direct photographs of star fields, comets, asteroids, Pluto, and Mars. The electronic library of images from photographic plates was created from scanning the astronomical negatives. We present information on programs scheduled at the telescope and the structure and maintenance of the plate stacks. We also list the plates with images of asteroids and comets. Access to all our plate lists is provided at the web sites of the Institute of Astronomy (INASAN) and WFPDB. It is possible to select plates by the date of observation, by the coordinates of the sky area, by the object type. Preview images can be inspected.

Authors: Matrozis E. , Začs L. , Barzdis A.
Published: March 2017

Element abundances for HD 209621 obtained earlier display significant discrepancies, especially in the case of CNO and neutron-capture elements. Therefore we performed a detailed analysis of chemical composition of this star using a new high-resolution spectrum. Atmospheric parameters and abundance pattern are updated, and the mechanism of nucleosynthesis is examined. Abundances for 11 elements are calculated for the first time. The method of atmospheric models and spectral synthesis was used. The following values of atmospheric parameters are derived: Teff = 4400 K, log g = 1.0 (cgs) and ξt = 1.9 kms−1. The iron abundance of the star was found to be low, at [Fe/H] = -1.91±0.10. The carbon to oxygen ratio is high, C/O ≃ +2.0. Low carbon to nitrogen ratio, [C/N] ≃ -0.8, and low carbon isotopic ratio, 12C/13C = 17 ±5, are in agreement with the theory of nucleosynthesis of intermediate-mass AGB stars. The barium to europium ratio is high, [Ba/Eu] = +0.28, and is typical for carbon-enhanced metal-poor CEMP-r/s stars. The observed abundance pattern of neutron capture elements is reproduced well by the scaled solar system abundances.

In a 1.5 square degree area, centered at RA = 21:44:30, DEC = +65:58, we have determined magnitudes and color indices for 2140 stars in the Vilnius seven-color system down to V = 17 mag. This area includes a star-forming region with the open cluster NGC 7129 embedded in a dense dust cloud TGU 645 (LDN 1181), close to the Cepheus Flare, and a distant old open cluster NGC 7142 seen through a semi-transparent window. For most of the stars spectral and luminosity classes in the MK system, determined from the photometric data, are given.

Published: March 2017

We present V - and I-passband photometry of massive stars in the Cyg OB1 and Cyg OB2 associations, based on about 80 observing nights spanning 300 days in the 2011 season. The variability of 22 supergiants and 48 OB-stars with luminosity classes III-V is analyzed. We report two new variable OB stars and 15 variable supergiants of which four are new discoveries. The light variations of Schulte 12 are interpreted as microvariability. We also present light curves of the red supergiants BC Cyg and BI Cyg which exhibit brightness drop of more than 0.4 mag during the season.

The Influence of Selected Drying Methods on the Physical Properties of Dried Apples cv. Jonagold Grown in Different Locations in Europe
Authors: Michalska Anna , Lech Krzysztof , Figiel Adam , Łysiak Grzegorz P.
Published: March 2017

The aim of the study was to determine the influence of four different growing locations of apples cv. ‘Jonagold’ in Europe on the drying kinetics and the physical properties of dried apple slices. The drying methods applied in the study (freeze-drying, convective drying, microwave-vacuum drying and combined drying) significantly affected the drying time, which was the shortest in the case of microwave vacuum drying. The geographical origin of the apples affected the chemical and physical properties of the raw material used for drying, and, consequently, the drying time. Water activity of dried samples was connected with the final dry matter, regardless of the geographical origin of the apples. Freeze-drying resulted in the lightest in colour products (L*), whereas microwave-vacuum dried products had the highest levels of yellow pigments (b*). The highest chroma and browning index values were noted for microwave-vacuum dried samples and were strongly influenced by the drying temperature. The mechanical properties of the apple slices were more dependent on the drying method and temperature of the process than on the geographical origin when the temperature exceeded 83 °C.

Authors: Li Li , Li Zhi-Rui
Published: March 2017

Radio over Fiber (RoF) is one of the solutions to the “last mile” because of its bandwidth advantage offered by fiber and the mobility and flexibility of wireless systems. In this paper, the transmission performance of DSB, SSB and OCS with three modulation formats is established, and a new single-sideband modulation single-mode optical fiber transmission model is proposed, and simulated analysis is done to the system. In this paper, 40 GHz millimeter-wave signal was generated by external modulation, and the received signal is received by coherent demodulation. In this paper, Matlab and VPI are used for combine programming simulation, DCF method was used to compensate the chromatic dispersion. Through the analysis of dispersion performance, Q value and bit error rate, we can see that the modified SSB modulation has the best transmission performance for 120 km links.
A Scheme for UDWDM-PON Broadband Access Network Using a Mode Locked Laser Diode and Optical Injection Locking
Authors: Chakraborty Meenakshi , Chattopadhyay Taraprasad
Published: March 2017

This paper describes an useful scheme of ultra-dense wavelength division multiplexed-passive optical network (UDWDM-PON) meant for the bidirectional transmission of analog video signals to the users in the Optical Network Unit (ONU). Each user has a dedicated wavelength which carries a group of analog video channels. This PON scheme is bidirectional with a long distance of transmission of 100 km typically over a single optical fiber. The video channels designated for a particular user in the ONU can be continuously tuned by a post-detection tunable bandpass filter. Intermodulation distortion (IMD) resulting from a mixing of analog video channels carried by a single wavelength has been calculated for a group of three video channels which lies in the range of –30 dB to –85 dB typically for a set of values of parameters used in practice. This IMD level is fairly acceptable for analog video signal transmission and reception in practice. The novelty of this scheme is that it is long reach.
Research Article. A new gravity laboratory in Ny-Ålesund, Svalbard

Published: March 2017

The Norwegian Mapping Authority (NMA) has recently established a new gravity laboratory in Ny-Ålesund at Svalbard, Norway. The laboratory consists of three independent pillars and is part of the geodetic core station that is presently under construction at Brandal, approximately 1.5 km north of NMA’s old station. In anticipation of future use of the new gravity laboratory, we present benchmark gravity values, gravity gradients, and final coordinates of all new pillars. Test measurements indicate a higher noise level at Brandal compared to the old station. The increased noise level is attributed to higher sensitivity to wind.We have also investigated possible consequences of moving to Brandal when it comes to the gravitational signal of present-day ice mass changes and ocean tide loading. Plausible models representing ice mass changes at the Svalbard archipelago indicate that the gravitational signal at Brandal may differ from that at the old site with a size detectable with modern gravimeters. Users of gravity data from Ny-Ålesund should, therefore, be cautious if future observations from the new observatory are used to extend the existing gravity record. Due to its lower elevation, Brandal is significantly less sensitive to gravitational ocean tide loading. In the future, Brandal will be the prime site for gravimetry in Ny-Ålesund. This ensures gravity measurements collocated with space geodetic techniques like VLBI, SLR, and GNSS.
