On bifurcation of the four Liouville tori in one generalized integrable model of the vortex dynamics
Authors: Ryabov P. E.
Published: August 2019

The article deals with a generalized mathematical model of the dynamics of two point vortices in the Bose-Einstein condensate enclosed in a harmonic trap, and of the dynamics of two point vortices in an ideal fluid bounded by a circular region. In the case of a positive vortex pair, which is of interest for physical experimental applications, a new bifurcation diagram is obtained, for which the bifurcation of four tori into one is indicated. The presence of bifurcations of three and four tori in the integrable model of vortex dynamics with positive intensities indicates a complex transition and the connection of bifurcation diagrams of both limit cases. Analytical results of this publication (the bifurcation diagram, the reduction to a system with one degree of freedom, the stability analysis) form the basis of computer simulation of absolute dynamics of vortices in a fixed coordinate system in the case of arbitrary values of the physical parameters of the model (the intensities, the vortex interaction and etc.).

In this case, the force fields have various dissipation and generalize the previously considered ones.
Change of geodynamic settings in the Eurasia - Pacific Transition Zone in the late early cretaceous
Authors: Didenko A. N. , Khanchuk A. I.
Published: August 2019

The paper seeks to explain in new ways the change in the geodynamic regime at the eastern margin of the Eurasian paleocontinent in the Early Cretaceous from the convergent type of plate boundary to the transform boundary. Certain global geodynamic characteristics were analyzed in the 200-65 Ma interval, which reflect the processes both at depth and on the Earth’s surface and are seemingly unrelated directly to the formation of the transform boundary in the east of Asia. The change of geodynamic regimes is found to occur within the 115 to 110 million years ago time range.
New geochemical criterion of rare metal mineralization in the peralkaline magmas (Lovozero mineral deposit, Kola Peninsula)
Authors: Kogarko L. N.
Published: August 2019

Detailed studies have shown that changing the forms of eudialyte release (and the time of its crystallization) is a new geochemical criterion for the ore - bearing of alkaline magmas for rare metal (eudialyte ores). A new ore-bearing principle of alkaline magmas has been formulated: a prerequisite for the formation of an ore deposit is the early saturation of alkaline magmas with respect to the ore mineral. If the concentration of the ore component is significantly lower than the cotectic concentration (saturation), then the melt saturation and crystallization of the ore mineral will be carried out at the later stages of rock formation in a small volume of interstitial melt, when the phenomena of convective-gravity differentiation and segregation of mineral phases in the form of ore deposits are hampered. This leads to the dispersion of ore components in the form of xenomorphic forms of accessory minerals. Rocks of the differentiated complex (lower zone of the Lovozero deposit), and of the Khibiny massif, containing xenomorphic eudialyte, are not promising for eudialyte ores. Eudialyte deposits are associated with the upper zone of the Lovozero intrusion containing idiomorphic early eudialyte. The saturation of the initial magma in relation to eudialyte occurs after crystallization of about 80% of the intrusion. The proposed criterion is applicable to the largest alkaline massifs in the world. With the Ilimaussaksky massif (Greenland), in the rocks of which early, crystallized, idiomorphic eudialyte, there is a superlarge eudialyte ore deposit while in the Khibiny eudialyte ore is absent.
Coesite inclusion in diamondferous kyanite-bearing eclogite from kimberlite pipe Udachnaya (Siberian Craton)
Authors: Mikhailenko D. S. , Korsakov A. V. , Rezvukhina O. V. , Golovin A. V. , Sobolev N. V.
Published: August 2019

A find of coesite in a kyanite graphite-diamond-bearing eclogite xenolith from the Udachnaya-Vostochnaya kimberlite pipe is described in this paper. The coesite relics were found in intensely fractured garnet indicating some influence of the kimberlite melt, which is supported by the typical secondary mineral assemblage around this inclusion. These data indicate that shallower diamond-free coesite rocks (2,7 GPa) underwent metamorphism distinct from diamond-bearing coesite eclogites (~4 GPa). The metasomatic alteration of rock interacting with C-O-H fluid during diamond crystallization may be another possible reason for the missing coesite in diamond-bearing xenoliths.

Published: August 2019

Day to day increasing vehicles usage for human activities is caused to accumulate greenhouse emissions into the environment. The biodiesel is a best alternative fuel to run diesel engines. But its lower Calorific value and higher NOx emissions makes the consumer should compromise with engine performance and emission characteristics. As we know, that the use of additives to improve engine Combustion and emissions are caused to increase the fuel cost due to the higher cost of additives. The biodiesel conversion process of third generation biodiesel is costlier and required technological advancements for qualitative fuel.
In the present work, the author used mixed culture micro algal particles in Coconut biodiesel (CCNME+AP) to improve engine characteristics. The Brake Thermal Efficiency (BTE) was enhanced, and the NOx emissions were less due to the absorption of heat in the Combustion chamber, it led to cool combustion phenomena with the Algal particles contained Coconut Biodiesel (CCNME+AP).

Published: August 2019

This article presents the work carried out to implement the use of solar thermal energy in a rehabilitation clinic located in southern Spain. The objective is to reduce the consumption of fossil fuels and improve energy sustainability and efficiency of clinical current processes and contribute to a better use of the abundant solar resources in this area. We have developed a strategy that allows better utilization of production of solar collectors. In the first phase we have designed a solar thermal system for domestic hot water supply of 30 double rooms (half the current capacity of the center) and pool heating. This pool is outdoors, with a capacity of 160 m3 and is used for medical treatment during the months of May to September. The management of the use of water heated in the collectors during this period has been established to give priority to the pool heating and the use of the excess energy to supply the hot water system. We have simulated the system performance using the F-char method. The results show that the designed system is able to cover 100% of the energy needs of the pool and cover 60% of the hot water needs of the 30 rooms. It can be stated that the use of this type of energy in facilities such as the one described in this paper allows maximizing the thermal energy produced and represent a significant saving of fossil fuels.
Numerical investigation of methanol bluff-body flame using variants of RANS turbulence models with conditional moment closure model
Authors: Roy R. N. , Sreedhara S.
Published: August 2019

In this article, conditional moment closure model (CMC) along with four variants of RANS turbulence models is used for investigating a methanol bluff-body flame. This work attempts to establish the accuracy of turbulence models in predicting the mixing fields, which results in improved predictions of the mean and variance of mixture fraction. This ensures an accurate probability density function (pdf) of the mixture fraction field which is used to obtain unconditional quantities from the conditional quantities calculated from CMC closure. The flow and mixing field are calculated using ANSYS Fluent software by incorporating four different turbulence models viz. standard k-ε (SKE), modified k-ε (MKE), RNG k-ε and Reynolds stress turbulence models. Flow field simulations have been coupled with an in-house CMC solver to obtain the mean flame structure. Profiles of mixture fraction showed an excellent agreement with the experimental data when Reynolds stress turbulence model was used. The unconditional mean temperature and species mass fraction obtained from the CMC model shows improved predictions when coupled with the Reynolds stress turbulence models. Because of inaccurate mixing field and hence the pdf predicted from SKE, MKE and RNG k-ε models, the unconditional quantities showed significant deviations from the experimental results.

Published: August 2019

Bali is known as a tourist destination which is always filled with tourists, both domestic and foreigners. Besides being famous for its culture, the beach is one of the main attractions for tourists. Berawa Beach is one that is always crowded with foreign tourists because it has large waves which are great for surfing and also to enjoy the beautiful sunset. This phenomenon provides opportunities for local people as a source of income by becoming food and beverage sellers around Berawa beach. This encourages local people to use English when they transact with foreign tourists. Practically, the English language used by traders is practical English with transactional functions. This study aims to describe the ability of English use by food and beverage traders in Berawa Beach, Tibubeneng village, North Kuta District, Badung Regency in terms of the speaking aspect. In order to determine the traders speaking ability, the researcher uses scoring rubric descriptions that contain several aspects such as, grammar, pronunciation, fluency, and vocabulary. Data is collected through several instruments such as interviews, direct observation, and field notes. The results of this study can be used as input for stakeholders of Tibubeneng Village to determine the steps in improving the English language skills of food and beverage traders who ultimately can contribute positively to Badung Regency in advancing the tourism industry while introducing various kinds of local culinary.
Sketch and Literacy
Authors: Fadlillah Anam
Published: August 2019

Identity is known as the concept of how people come to understand themselves through the “worlds” they participate in and how they relate to others within and outside of these worlds. However, their identity that is constructed within their figured worlds give significant impact to their literacy practices, in which their literacy event, unconsciously, showed their identity and figured worlds that they participate in. This paper investigates one post-graduate student’s literacy event, sketching, by using the concept of figured worlds, in which it focused on figuring out how the figured worlds construct her identity in her literacy practices. The data were collected by taking photographs of the literacy events and interviewing to find out her cultural life, family, and social life that construct her identity. The findings of the study showed that somebody’s literacy events have a lot of implicit meaning rather than just a product of literacy practices.

Quadrupole Time-of-Flight Mass Spectrometry: A Paradigm Shift in Toxicology Screening Applications
Authors: Allen Darren , McWhinney Brett
Published: August 2019

The screening of biological samples for the presence of illicit or legal substances is an important frontline tool in both clinical and forensic toxicology. In the clinical setting, drug screening is a useful tool for the clinician in improving patient care and guiding treatment. Analytical approaches for the screening of drugs in biological samples are extensive and well documented, though many rapid screening techniques often lack appropriate sensitivity and specificity, requiring careful clinical interpretation. The continuous emergence of new psychoactive substances presents a considerable analytical challenge in maintaining up-to-date methods for the detection of relevant drugs. Adapting and validating methods for the detection of new substances can be a complicated and costly undertaking. There is also a considerable lag time between the emergence of new drugs and the release of commercial assays for detection. Quadrupole time-of-flight mass spectrometry (Q-TOF-MS) has gained considerable attention over the last decade as an analytical technique that is capable of meeting the challenges of a rapidly changing drug landscape. Exhibiting both high sensitivity and specificity in drug detection, Q-TOF-MS also allows methods to be rapidly updated for newly emerging psychoactive agents. The coupling of Q-TOF-MS with techniques such as liquid or gas chromatography can provide both rapid and comprehensive screening solutions that are gaining popularity in the clinical laboratory setting.
FOUNDATION PHASE STUDENTS’ METACOGNITIVE ABILITIES IN MATHEMATICS CLASSES: REFLECTIVE CLASSROOM DISCOURSE USING AN OPEN APPROACH
Authors: Tachie Simon Adjei
Published: August 2019

The research findings describe a model of experiential learning that promotes the development of foundation phase student teachers’ metacognitive abilities for mathematics through classroom reflective discourse using an open approach. A case study was carried out on two foundation phase mathematics classes in South Africa’s universities; data were collected through observation and focus group interviews. The research’s main findings indicated that student teachers’ interest in reflective classroom discourse is important using an open-approach-based mathematics class, which helped pave the way for the student teachers to exhibit metacognitive abilities relevant to the teaching and learning steps of a foundation phase mathematics class. Deciding on the type of problem to work on, posing open-ended problems to colleagues for discussion in class, stimulating students’ reflective self-centred learning, whole-class discussion, comparison of a particular problem and summarising important information for self-development in teaching and learning through connecting students’ mathematical ideas all formed part of reflective classroom discourse. Recommendations were made for further development of metacognitive abilities. Keywords: mathematics class, metacognitive strategies, open approach, preservice teachers, reflective classroom, school learners, student teachers.
Formy profesjonalizmu lekarskiego i ich przydatność w edukacji moralnej studentów medycyny i młodych lekarzy
Authors: Szewczyk Kazimierz
Published: August 2019

W pierwszej części artykułu charakteryzuję trzy rodzaje profesjonalizmu lekarskiego: profesjonalizm tradycyjny, odnowiony i kompleksowy. Omawiam także czynniki kulturowe, ekonomiczne i aksjologiczne wpływające na ich kształtowanie się. Stawiam tezę, że profesjonalizm kompleksowy ze względu na jego skomplikowanie i arbitralne wyodrębnianie elementów składowych jest nieprzydatny w edukacji moralnej studentów i lekarzy. W części drugiej rekonstruuję wady i zalety profesjonalizmu tradycyjnego i odnowionego. Uzasadniam pogląd, że najważniejsza zaleta profesjonalizmu wynika z jego ambiwalencji moralnej. Nie traktuję więc tej dwuznaczności jako wyłącznie wady. Lekarz profesjonalista powinien mieć świadomość jasnych i ciemnych stron profesjonalizmu oraz umiejętność właściwego ich ważenia w danych okolicznościach – poszukiwania Arystotelesowskiego złotego środka. W ostatniej części argumentuję za umiarkowanie optymistycznym przekonaniem o przydatności profesjonalizmu tradycyjnego i odnowionego w moralnym formowaniu studentów medycyny i młodych lekarzy.

De acuerdo con la Organización Mundial de la Salud (OMS), hay 802 millones de personas entre niños en edad pre-escolar, y mujeres en edad reproductiva que son diagnosticadas de anemia. Estas cifras muestran un panorama poco alentador para los gobiernos, puesto que vemos el gran énfasis  en los programas de suplementación de hierro, con distribución a nivel nacional. Sin embargo, los valores reportados en las encuestas y las grandes bases de datos que se utilizan para la elaboración de estadísticas nacionales se basa en la medición de la hemoglobina mediante el equipo HemoCue®, que presenta variantes entre los equipos y que reportan valores que no permiten determinar la causa de la anemia, basando la intervención solo en la suplementación de hierro, cuando a nivel mundial se ha determinado que solo el 50% de casos de anemia se deben a deficiencia de hierro, 42% a causas inflamatorias y 8% a otras causas. En el reporte de 2016, la OMS recomendó como primera prioridad la evaluación del hemograma completo para definir anemia, y cuando no exista esta facilidad usar la medición de la hemoglobina.  En la presente revisión narrativa se hará un análisis de cada metodología y la utilidad tanto para la práctica clínica como para el uso poblacional en el diagnóstico de la anemia gestacional.
Imputation of Missing Values in Economic and Financial Time Series Data Using Five Principal Component Analysis (PCA) Approaches
Authors: John Chisimkwuo , Ekpenyong Emmanuel J. , Nworu Charles C.
Published: August 2019

This study assessed five approaches for imputing missing values. The evaluated methods include Singular Value Decomposition Imputation (svdPCA), Bayesian imputation (bPCA), Probabilistic imputation (pPCA), Non-Linear Iterative Partial Least squares imputation (nipalsPCA) and Local Least Squares imputation (llsPCA). A 5%, 10%, 15% and 20% missing data were created under a missing completely at random (MCAR) assumption using five (5) variables (Net Foreign Assets (NFA), Credit to Core Private Sector (CCP), Reserve Money (RM), Narrow Money (M1), Private Sector Demand Deposits (PSDD) from Nigeria quarterly monetary aggregate dataset from 1981 to 2019 using R-software. The data were collected from the Central Bank of Nigeria statistical bulletin. The five imputation methods were used to estimate the artificially generated missing values. The performances of the PCA imputation approaches were evaluated based on the Mean Forecast Error (MFE), Root Mean Squared Error (RMSE) and Normalized Root Mean Squared Error (NRMSE) criteria. The result suggests that the bPCA, llsPCA and pPCA methods performed better than other imputation methods with the bPCA being the more appropriate method and llsPCA, the best method as it appears to be more stable than others in terms of the proportion of missingness.
Obtaining Patient Information and Anxiety in Novice Nursing Students
During the First Clinical Rotation
Authors: Akiko Kobayashi
Published: August 2019

Background: Gathering comprehensive patient information at the beginning of the shift is essential for effective nursing practice. Novice nursing students (NSs) feel highly anxious, and obtaining patient information is a challenge. There is limited knowledge regarding the ability of novice NSs to gather essential patient information from the previous shift. This study was conducted to assess the anxiety levels of novice NSs and the types of patient information obtained by them and sources that NSs utilized when they obtained patient information.

Methods: The anxiety levels of NSs were compared between the beginning, midpoint and the end of the first clinical rotation. The patient information items that NSs obtained and the sources that NSs utilized were also compared between these assessment points.

Results: As anticipated, the anxiety levels were the highest on the first day and progressively decreased throughout the first rotation. As for the gathering of patient information from the previous shift, progressively increased numbers of NSs obtained early morning laboratory data, and the majority of NSs obtained them by the end of the first rotation. A steady increase was also seen in obtaining vital signs (VSs) from the previous shift but the number did not reach 100% of NSs even on the last clinical day. Less than half of the NSs obtained the previous shift’s patients’ pain levels throughout the rotation. The computer use was consistently the most popular source of patient information. There was no increase in utilization of RNs, either day-shift or night-shift as the information source during the rotation.

Conclusion: The novice NSs did not show consistent improvement in gathering essential patient information during the first clinical rotation. It is important to remind NSs to obtain all essential patient information periodically and to encourage them to obtain patient information from the shift report.

Development of wheat—Hordeum chilense Chromosome 2Hch Introgression Lines Potentially Useful for Improving Grain Quality Traits
Authors: Palomino Carmen , Cabrera Adoracion
Published: August 2019

The chromosome 2Hch of Hordeum chilense. has the potential to improve seed carotenoid content in wheat as it carries a set of endosperm carotenoid-related genes. We have obtained structural changes in chromosome 2Hch in a common wheat (Triticum aestivum L. “Chinese Spring”) background by crossing a wheat double disomic substitution 2Hch(2D) and 7Hch(7D) line with a disomic addition line carrying chromosome 2Cc from Aegilops cylindrica Host.. Seven introgressions of chromosome 2Hch into wheat were characterized by fluorescence in situ hybridization (FISH) and DNA markers. Chromosome-specific simple sequence repeats (SSRs) were used for identifying wheat chromosomes. In addition, we tested 82 conserved orthologous set (COS) markers for homoeologous group 2, of which 65 amplified targets in H. chilense and 26 showed polymorphism between H. chilense and wheat. A total of 24 markers were assigned to chromosome 2Hch with eight allocated to 2HchS and 16 to 2HchL. Among the seven introgressions there was a disomic substitution line 2Hch(2D), a ditelosomic addition line for the 2HchL arm, an isochromosome for the 2HchL arm, a homozygous centromeric 2HchS·2DL translocation, a double monosomic 2HchS·2DL plus 7HchS·D translocation, a homozygous centromeric 7HchS·2HchL translocation and, finally, a 2HchL·7HchL translocation. Wheat—H. chilense macrosyntenic comparisons using COS markers revealed that H. chilense chromosome 2Hch exhibits synteny to wheat homoeologous group 2 chromosomes, and the COS markers assigned to this chromosome will facilitate alien gene introgression into wheat. The genetic stocks developed here include new wheat—H. chilense recombinations which are useful for studying the effect of chromosome 2Hch on grain quality traits.
