Determination of Abundances of Chemical Elements in Open Star Clusters of the Galaxy
Authors: Gozha M. L. , Koval’ V. V. , Marsakov V. A. 
Published: February 2017

Abstract
Spectroscopic determinations of the relative abundances of chemical elements produced in different nuclear-synthesis processes, [el/Fe], are collected for 90 open star clusters of the Galaxy using data from 109 papers published between 1991 and 2015. Information is gathered on the abundances of α-elements (O, Mg, Si, Ca, and Ti), iron-peak element (Fe), slow neutron capture elements (Y, Ba, La, Ce, Nd, and Zr), rapid neutron capture element (Eu), and elements with an odd number of protons (Na, Al). The weighted averages are calculated for the clusters with more than one determination of the abundances of each studied chemical element. Estimates of metallicities are found for 346 clusters. A compiled catalog of the open cluster parameters contains metallicities, positions, ages, velocities, elements of Galactic orbits, and relative abundances of fourteen chemical elements.
The Study of Radio Flux Density Variations of the Quasar OJ 287 by the Wavelet and the Singular Spectrum Methods
Authors: Donskykh Ganna 
Published: February 2017

AbstractFlux density variations of the extragalactic radio source OJ 287 are studied by applying the wavelet and the singular spectrum methods to the long-term monitoring data at 14.5, 8.0 and 4.8 GHz acquired at the University of Michigan Radio Astronomy Observatory during 40 years. This monitoring significantly supplements the episodic VLBI data. The wavelet analysis at all three frequencies revealed the presence of quasiperiods within the intervals 6.0–7.4 and 1.2–1.8 years. The singular spectrum analysis revealed the presence of quasiperiods within the intervals 6–10 and 1.6–4.0 years. For each quasiperiod the time interval of its existence was determined.

Authors: Mylläri A. , Orlov V. , Chernin A. , Martynova A. , Mylläri T. 
Published: February 2017

Abstract
We use symbolic dynamics in the classic equal-mass free-fall three-body problem. Different methods for constructing symbolic sequences (in the process of numerical integration of trajectories) allow one to demonstrate (and illustrate on the Agekian-Anosova map) sensitivity to initial conditions, estimate entropies (Shannon, Markov and others), plot binary collision curves, reveal systems with intensive triple interactions (interplay), etc.
Estimating the Vertical Disk Scale Height Using Young Galactic Objects
Authors: Bobylev V. V. , Bajkova A. T. 
Published: February 2017

Abstract
We compiled published data on young Galactic objects such as masers with VLBI-measured trigonometric parallaxes, OB associations, H II regions and Cepheids. We have recently established that the vertical disk scale height is strongly influenced by objects of the Local arm. In this study we use samples that do not contain objects in this arm and derive the following vertical disk scale heights in terms of the self-gravitating isothermal disk model for the density distribution: h = 46±5 pc for 69 masers with trigonometric parallaxes, h = 36 ± 3 pc for 59 OB associations, h = 35.6 ± 2.7 pc for 147 H II regions, h = 52.1 ± 1.9 pc for 195 young Cepheids, and h = 72.0 ± 2.3 pc for 192 old Cepheids.

A Quasi-Stationary Twisted Disk Formed as a Result of a Tidal Disruption Event
Authors: Xiang-Gruess M. , Ivanov P. B. , Papaloizou J. C. B. 
Published: February 2017

Abstract
In this note we briefly review the main results of our recent study of the formation of misaligned accretion disks after the tidal disruption of stars by rotating supermassive black holes. Since the accretion rates in such disks initially exceed the Eddington limit they are initially advection dominated. Assuming the α model for the disk viscosity implies that the disk can become thermally unstable when the accretion rate is comparable to, or smaller than, the Eddington value, while still being radiation pressure dominated. It then undergoes cyclic transitions between high and low states. During these transitions the aspect ratio varies from ~1 to ~10−3, which is reflected in changes in the degree of disk misalignment at the stream impact location. For maximal black hole rotation and sufiociently large values of the viscosity parameter, α ≳ 0.01–0.1, the ratio of the disk inclination to that of the initial stellar orbit is estimated to be 0.1–0.2 in the advection dominated state, while reaching order unity in the low state. Misalignment decreases with decrease of α, but increases as the black hole rotation parameter decreases. Thus, it is always significant when the latter is small.
Orbits of Wide Binaries – New Possibilities
Authors: Kiyaeva Olga V. 
Published: February 2017

Abstract
We use the Apparent Motion Parameters (AMP) method for the determination of orbits of visual double stars (Kiselev & Kiyaeva 1980). The quality of AMP orbits is completely dependent on the precision of parameters of relative positions and motions at the same instant. They are calculated on the basis of a short arc of observations. To determine these parameters, we use recent high precision observations obtained with the best modern techniques. New orbits of three stars are presented.
Details of the Classification of Symbiotic Stars: The Case of the Symbiotic Nova AG Peg
Authors: Tatarnikova A. A. , Burlak M. A. , Popolitova D. V. , Tarasova T. N. , Tatarnikov A. M. 
Published: February 2017

Abstract
We analyze archival and modern spectroscopic and photometric observations of the oldest known symbiotic nova AG Peg. Its new outburst (which began in 2015 June) differs greatly from the first one (which occurred in the mid-1850s). Fast photometric evolution of the new outburst is similar to that of Z And-type outbursts. However, the SED of AG Peg during the 2015 outburst, as well as during the quiescence, can be fitted by a standard three-component model (cool component + hot component + nebula), which is not common for an Z And-type outburst.
Molecular Clouds and Star Formation Rate in Disk Galaxies

Published: February 2017

Abstract
We use N-body/hydrodynamic simulations of a Milky Way-like galaxy to study the physical properties of giant molecular clouds and star formation rate on different spatial scales. We confirm the previous estimates that the dark gas fraction in molecular clouds reaches about 30% by mass. We find that conversion factors for individual molecular clouds deviated by a factor of several times from the mean value for the Milky Way clouds, X
CO = 2 × 1020 cm−2 (K km s−1)−1, and hence a constant X
CO conversion factor cannot represent the physical properties of an individual molecular cloud or a small sample of clouds sufficiently well, but the conversion factor averaged over the whole ensemble of clouds is believed to be close to the MilkyWay value. The

Developing Visual Perception as a Stimulator of Artistic Activities of Children
Authors: Szuścik Urszula 
Published: February 2017

Abstract
I would like to present research in the field of art – specifically, in the artistic education of younger school children. The natural pedagogical experiment consisted of carrying out an art education programme aimed at developing the visual perception of children with regard to visual qualities, i.e. colour, line and solid representations. In the first part of experiment the children learned about these basic visual qualities and produced free interpretations of them. In the second part of the experiment the artistic problem of contrast in the learned visual qualities appeared. During the third part of the experiment children perceived the familiar qualities in relative relations. As visual perception determines the character and quality of artistic activities in children in such a significant way, it seems worth trying to revise the system of developing their artistic activities that has been used so far in art education.
Overcoming Impasses in Conversations: A Creative Business
Authors: Torre Ilaria , Loesche Frank 
Published: February 2017

Abstract
The ability to communicate complex meanings is a specific human ability which plays a crucial role in social interactions. A habitual example of these interactions is conversation. However, we observe that spontaneous conversation often hits an impasse when none of the interlocutors immediately produces a follow-up utterance. The existence of impasses in conversations, and the way that interlocutors overcome them provide evidence for our argument that conversation is a sequence of creative problem solving. In this work we use techniques from Conversation Analysis (CA) on publicly available databases of naturally-occurring speech and we suggest a framework to understand how impasses are reached and overcome. As a result, we hope to reveal yet another instance of the bond between language and creativity.
The Role of Orbitofrontal–Amygdala Interactions in Updating Action–Outcome Valuations in Macaques

Published: February 2017

A previous study revealed that, although monkeys with bilateral lesions of either the orbitofrontal cortex (OFC) or the amygdala could learn an action–outcome task, they could not adapt their choices in response to devalued outcomes. Specifically, they could not adjust their choice between two actions after the value of the outcome associated with one of the actions had decreased. Here, we investigated whether OFC needs to interact functionally with the amygdala in mediating such choices. Rhesus monkeys were trained to make two mutually exclusive actions on a touch-sensitive screen: “tap” and “hold.” Taps led to the availability of one kind of food outcome; holds produced a different food. On each trial, monkeys could choose either a tap or a hold to earn the corresponding food reward. After consuming one of the two foods to satiety, monkeys were then tested on their ability to adapt their choices in response to the updated relative valuation of the two predicted outcomes. Whereas intact (control) monkeys shifted their choices toward the action associated with the higher value (nonsated) food, monkeys with crossed surgical disconnection of the amygdala and OFC did not. These findings demonstrate that amygdala–OFC interactions are necessary for choices among actions based on the updated value of predicted outcomes and they also have a bearing on the idea that OFC specializes in stimulus- or object-based choices in contrast to action- or response-based choices.SIGNIFICANCE STATEMENTDysfunctional interactions between orbitofrontal cortex (OFC) and the amygdala underlie several mental health disorders, often related to value-based decision making. Understanding the underlying neural circuitry may help to develop therapies for those suffering from mood and anxiety disorders and provide insight into addiction. Here, we investigated whether the amygdala must interact with OFC to make adaptive choices. Monkeys learned to perform two different actions, “tap” for one kind of food reward and “hold” for another, and then one of the two foods was devalued temporarily. Intact monkeys shifted their choice to whichever action produced the higher-value food; monkeys with crossed surgical disconnection of OFC and the amygdala did not. Therefore, OFC and the amygdala must interact functionally to mediate adaptive choices.

The growing number of the elderly population, so health related problems also will increase. Mental health concerns are among the most important health problems in the management of the elderly. From research was found that people who experience stress have a higher risk of developing hypertension, 2.5 times more than those who do not experience stress. In May 2013, 54% of elderly people in the region in tabanan second primary health centerâ€™s region at tabanan regency have been diagnosed with hypertension,.This study aims to determine the relationship of stress on the degree of hypertension, that suffered by elderly people treated at in Tabanan second primary health centerâ€™s region at Tabanan regency. The study carried out in September-October 2013, using a study design with cross sectional analysis. Data collection in the study was done in two stages of work, primary data through interviews conducted by questionnaires from house to house and secondary data obtained from the information available at primary health centerâ€™s .Â The results showed that the respondents with hypertension, grade I status as many as 41 people (75.9%) experienced stress while respondents with hypertension, grade II status as many as 27 people (81.8%) experienced stress. Kendall correlation test results for the variable stress levels with the degree of hypertension, showed a correlation coefficient of 0.069 with p = 0.521. These results show a correlation between stress and the the degree of hypertension, in the same direction. However, the price of the correlation coefficient between stress and the degree of hypertension showed a very weak relationship between stress and the degree of hypertension, (0.069 <0.2). When viewed from the price of p = 0.521 (> 0.05) so there is no significant correlation between the two variables.
MENEKAN LAJU PENYEBARAN KOLERA DI ASIA DENGAN 3SW (STERILIZATION, SEWAGE, SOURCES, AND WATER PURIFICATION)

Penyakit taun atau kolera (juga disebut Asiatic cholera) adalah penyakit menular di saluran pencernaan yang disebabkan oleh bakterium Vibrio cholerae. Kolera ditemukan pada tahun 1883 karena infeksi Vibrio cholerae, bakteri berbentuk koma. Penemuan ini ditemukan oleh bakteriologi Robert Koch (Jerman, 1843-1910).Penyebab kolera, adalah bakteri Vibrio cholerae, yang merupakan bakteri gram negatif, berbentuk basil (batang) dan bersifat motil (dapat bergerak), memiliki struktur antogenik dari antigen flagelar H dan antigen somatik O, gamma-proteobacteria, mesofilik dan kemoorganotrof, berhabitat alami di lingkungan akuatik dan umumnya berasosiasi dengan eukariot.Â Pada orang yang feacesnya ditemukan bakteri kolera mungkin selama 1-2 minggu belum merasakan keluhan berarti, Tetapi saat terjadinya serangan infeksi maka tiba-tiba terjadi diare dan muntah dengan kondisi cukup serius sebagai serangan akut yang menyebabkan samarnya jenis diare yg dialamiCara pencegahan dan memutuskan tali penularan penyakit kolera adalah dengan prinsip sanitasi lingkungan, terutama kebersihan air dan pembuangan kotoran (feaces) pada tempatnya yang memenuhi standar lingkungan. Lainnya ialah meminum air yang sudah dimasak terlebih dahulu, cuci tangan dengan bersih sebelum makan memakai sabun/antiseptik, cuci sayuran dangan air bersih terutama sayuran yang dimakan mentah (lalapan), hindari memakan ikan dan kerang yang dimasak setengah matang.Kolera memang sudah menjadi momok yang menakutkan di dunia, dan belajar dari negara-negara di Asia yang sudah pernah mengalami wabah kolera, dapat diambil kesimpulan bahwa pengobatan dengan vaksin tidak memiliki pengaruh yang signifikan.Selain karena tidak menjangkau seluruh warga miskin di sebuah negara, harga vaksin kolera juga dirasa cukup memberatkan anggaran negara-negara yang sedang berkembang di Asia.Cara yang dirasa paling tepat dalam menekan laju penyebara kolera adalah 3SW (Sterilization, Sewage, Sources, and Water purification), hal ini mengingatkan kita untuk menjaga keseimbangan Agent, Host, dan Environment.Gangguan pada environment (lingkungan), alam di sekitar kita, akhirnya menyebabkan ketidakseimbangan di sebuah daerah dan akhirnya membawa bencana di wilayah tersebut.Â

Demam tifoid disebabkan oleh bakteri Salmonella typhi, dengan gejala umum berupa demam tinggi dan nyeri perut. Tifoid adalah penyakit infeksi yang disebabkan oleh bakteri Salmonella typhi, yang masuk ke dalam tubuh melalui mulut dan saluran cerna.1Untuk bisa memahami patogenesis dari demam tifoid sampai ke tingkat selular dan molekular, ada 5 hal penting yang harus digaris bawahi, yaitu:1. Tipe 3 Sistem Sekresi (T3SS)2. Virulence Genes dari Salmonella yang mengkode 5 SIP (Salmonella Invasion Protein) SIP A, B, C, D, dan E.3. Toll R2 dan toll R3 yang merupakan lapisan luar dari makrofag.4. Sistem imun lumen usus sampai ke organ dalam5. Fungsi endotelial sel dalam inflamasi.Infeksi Salmonella dapat berakibat fatal kepada bayi, balita, ibu hamil dan kandungannya serta orang lanjut usia. Hal ini disebabkan karena kekebalan tubuh mereka yang menurun. Virulensi salmonella tidak lepas dari peranan SPI, yang terletak di dalam kromosom dan plasmid bakteri.Â Dimana SPI 1 dan SPI 2 telah dikaji cukup mendalam karena keterkaitannya dengan T3SS, dan berperan sangat penting pada invasi awal serta siklus hidup intrasel dari bakteri Salmonella.Kontaminasi Salmonella dapat dicegah dengan mencuci tangan dan menjaga kebersihan makanan yang dikonsumsi. Selalu menjaga kebersihan lingkungan hidup kita agar terhindar dari kontaminasi dengan bakteri Salmonella typhi. Agar mewaspadai sejak dini pencegahan dan pengobatan penyakit typhus.Â Studi mendalam perlu dilakukan agar kita mampu lebih memahami proses kompleks antara patogen dan sel inang. Mengingat dari 15 SPI yang sudah diketahui, hanya SPI 1 dan SPI 2 yang sudah dikaji secara mendalam.
