Authors: Johnson Grace C. , Christensen Monica 
Published: February 2018

A 23-year-old woman initiated a running program and after 2 months began experiencing right hip joint pain and sharp pain at the iliac crest. Following evaluation by her primary care physician, she was referred to a physical therapist. Eighteen months later, the patient had developed a bony prominence at the iliac crest that was painful to touch. She returned to see her primary care physician. Radiographs of the right hip and pelvis were completed and showed a lytic lesion that warranted additional imaging. Computed tomography and magnetic resonance imaging precontrast and postcontrast were performed, and the patient was referred to an orthopaedic oncologist. Conclusive laboratory testing determined that the tumor was a chondromyxoid fibroma J Orthop Sports Phys Ther 2018;48(2):122. doi:10.2519/jospt.2018.7551

Professional Competence of Student Teachers to Implement Species Identification in Schools – A Case Study from Germany
Authors: Lindemann-Mathies Petra , Remmele Martin , Yli-Panula Eija 
Published: February 2018

This study investigates how well prepared student teachers are to implement species identification in school. Data were collected with the help of a questionnaire and a PowerPoint presentation in which local plant and animal species were presented. Participants (n = 357) correctly identified, on average, 23% of the plants and 44% of the animals. They identified plants mainly by flower characteristics and leaves, and animals mainly by shape and colour. Family and school were key sources of participants’ knowledge of species. The self-estimated competence of participants to identify species was positively correlated with their taxonomic knowledge and the amount of time they had spent on species identification during their own schooldays. The number of correctly identified plant and animal species increased with interest in identifying species and participation in species identification courses. Participants considered learner-centred education and experience-based learning, and the use of living organisms to be most important when identifying species in school.
Scientific Conceptions of Photosynthesis among Primary School Pupils and Student Teachers of Biology
Authors: Skribe Dimec Darja , Strgar Jelka 
Published: February 2018

Photosynthesis is the most important biochemical process on Earth. Most living beings depend on it directly or indirectly. Knowledge about photosynthesis enables us to understand how the world functions as an ecosystem and how photosynthesis acts as a bridge between the non-living and living worlds. It is, therefore, understandable that photosynthesis is included in national curricula around the world. The practice unfortunately shows that students at all school levels mostly learn about photosynthesis by rote. Consequently, they have difficulties understanding this vital process. Research also shows many misconceptions in relation to photosynthesis among students of different ages. Based on these, the main aim of our study was to explore the scientific conceptions about photosynthesis held by primary school pupils and student teachers of biology. Data were collected using a questionnaire containing seven biology content questions.The sample consisted of 634 participants, 427 primary school pupils (aged 11–14), and 207 student teachers of biology (aged 20–23). We found that the populations of primary school pupils and student teachers of biology differ greatly concerning scientific conceptions of photosynthesis. The student teachers showed good and complex understanding of photosynthesis, while pupils showed some misconceptions (location of chlorophyll and photosynthesis in a plant, transformation of energy in photosynthesis). Analysis of the development of scientific conceptions about photosynthesis with age showed that there is very little progress among primary school pupils and none among biology student teachers. More involvement of student teachers of biology in practical work at primary schools during their study was suggested to make student teachers aware of, and better understand pupils’ misconceptions.
On Generalizations of phi-2-Absorbing Primary Submodules
Authors: Yiarayong Pairote , Siripitukdet Manoj 
Published: February 2018

Let $\phi: S(M) \rightarrow S(M) \cup \left\lbrace \emptyset\right\rbrace $ be a function where $S(M)$ is the set of all submodules of $M$. In this paper, we extend the concept of $\phi$-$2$-absorbing primary submodules to the context of $\phi$-$2$-absorbing semi-primary submodules. A proper submodule $N$ of $M$ is called a $\phi$-$2$-absorbing semi-primary submodule, if for each $m \in M$ and $a_{1}, a_{2}\in R$ with $a_{1}a_{2}m \in N - \phi(N)$, then $a_{1}a_{2}\in \sqrt{(N : M)}$ orÂ $a_{1}m \in N$ or $a^{n}_{2}m\in N$, for some positive integer $n$. Those are extended from $2$-absorbing primary, weakly $2$-absorbing primary, almost $2$-absorbing primary, $\phi_{n}$-$2$-absorbing primary, $\omega$-$2$-absorbing primary and $\phi$-$2$-absorbing primary submodules, respectively. Some characterizations of $2$-absorbing semi-primary, $\phi_{n}$-$2$-absorbing semi-primary and $\phi$-$2$-absorbing semi-primary submodules are obtained. Moreover, we investigate relationships between $2$-absorbing semi-primary, $\phi_{n}$-$2$-absorbing semi-primary and $\phi$-primary submodules of modules over commutative rings. Finally, we obtain necessary and sufficient conditions of a $\phi$-$\phi$-$2$-absorbing semi-primary in order to be a $\phi$-$2$-absorbing semi-primary.

Kurzfassung
Für die Orientierung in den Tiefen der Ozeane entwickelten Wale und Delphine im Laufe der Evolution ein spezialisiertes Hörorgan für ein breites akustisches Spektrum. Die innere Anatomie des Felsenbeins (Perioticum), insbesondere die Morphologie der Hörschnecke (Cochlea) hat bei Säugetieren einen signifikanten Einfluss auf das Hörvermögen. Mittels Röntgen- und Neutronentomographie wird die knöcherne oder fossilisierte Cochlea verschiedener fossiler Repräsentanten ausgestorbener Bartenwalgruppen (wie der Cetotheriidae) sowie moderner Furchenwale (Balaenopteridae) und Glattwale untersucht, ebenso die eines Urwals und einiger Landwirbeltiere. Morphologische Veränderungen, die für die Entwicklung des niederfrequenten Hörens verantwortlich sein können, sollen so erfasst werden. Unterschiede in der Cochlea-Morphologie werden anhand morphometrischer Parameter, wie der Anzahl der Windungen, der Länge der Cochlea und des Krümmungsverlaufs des Cochleakanals bestimmt. Insbesondere die Röntgentomographie ermöglicht eine hochauflösende Darstellung des knöchernen Innenohrs.

Published: February 2018

Demand forecasts are extremely important for manufacturing industry and also needed for all type of business and business suppliers for distribution of finish products to the consumer on time. This study is concerned with the determination of accurate models for forecasting cement demand. In this connection this paper presents results obtained by using a self-organizing model and compares them with those obtained by usual statistical techniques. For this purpose, Monthly sales data of a typical cement ranging from January, 2007 to February, 2016 were collected. A nonlinear modelling technique based on Group Method of Data Handling (GMDH) is considered here to derive forecasts. Forecast were also made by using various time series smoothing techniques such as exponential smoothing, double exponential smoothing, moving average, weightage moving average and regression method. The actual data were compared to the forecast generated by the time series model and GMDH model. The mean absolute deviation (MAD, mean absolute percentage error (MAPE) and mean square error (MSE) were also calculated for comparing the forecasting accuracy. The comparison of modelling results shows that the GMDH model perform better than other statistical models based on terms of mean absolute deviation (MAD), mean absolute percentage error (MAPE) and mean square error (MSE).

Published: February 2018

Flow control is a significant topic of research in the field of aviation. Researchers in this field are continuously trying their best to find various flow control strategies in order to extract aerodynamic benefits by applying them. Applying moving surface at the leading edge of aerofoil is a type of strategy among the various types of active flow control strategies. In the present research work a rotating cylinder is added on the leading edge of the aerofoil as a moving surface in order to control the flow over its surface. The moving surface boundary layer control is applied to NACA 0018 airfoil for investigating its aerodynamic benefits and effectiveness. The moving surface is created by rotating a smooth cylinder at the leading edge of the aerofoil. The peripheral velocity of the cylinder injects momentum to the upper surface boundary layer of the aerofoil and thus delays its separation. This results in the gain in both the maximum lift coefficient and the stall angle. The work has been done at four different Reynolds Number i.e., at Re = 1.4 X 10^5, 1.85 X 10^5, 2.3 X 10^5, 2.8 X 10^5 at different angles of attack.
La diffusion des meules dans la vallée de l'Hérault à l'époque protohistorique et l'identification microtexturale des basaltes
Authors: Reille Jean-Louis 
Published: February 2018

Quelques meules basaltiques de l'oppidum protohistorique de la Ramasse (moyenne vallée de l'Hérault, Languedoc central) ont fait l'objet d'une analyse pétrographique détaillée, en vue de déterminer leur provenance. La comparaison des microtextures qu'on y observe avec celles des basaltes du littoral et de la vallée de l'Hérault, a permis la caractérisation des sites de production. Ainsi, les meules du type va-et-vient sont taillées dans un même basalte local (coulée de Lacoste). En revanche, les meules rotatives sont des produits d'importation. Contre toute attente, leur matériau constitutif ne provient pas du Cap d'Agde mais du volcan de Saint Thibéry, où l'on peut envisager l'existence d'un centre de production indigène jusque là insoupçonné.
A partir de la caractérisation pétrographique de l'ensemble des sources régionales, une étude globale de la diffusion spatiale des meules en basalte, à diverses époques, paraît envisageable pour la Gaule méditerranéenne.
La poterne de l'oppidum d'Entremont

Published: February 2018

The postern from the Entremont oppidum.
The authors present the results of an archaeological and architectural study of the converted postern in the rampart, which surrounded the northern and eastern extension of the settlement from the middle of the second century BC. Two major phases are brought to light. In its oldest phase, the passage was only about 1.3 m wide, with a flight of 21 steps giving access to the door for which we have found the post-hole designed to receive the shaft. This phase was then destroyed and the passage obstructed. The second phase is characterised by the reopening and enlarging of the postern.

Published: February 2018

Abstract
High-redshift blazars are one of the most powerful sources in the universe and γ-ray variability carries crucial information about their relativistic jets. In this work we present results of the first systematical temporal analysis of Fermi-LAT data of all known seven γ-ray blazars beyond redshift 3. Significant long-term γ-ray variability is found from five sources in monthly γ-ray light curves, in which three of them are reported for the first time. Furthermore, intraday γ-ray variations are detected from NVSS J053954−283956 and NVSS J080518+614423. The doubling variability timescale of the former source is limited as short as ≲1 hr (at the source frame). Together with variability amplitude over one order of magnitude, NVSS J053954−283956 is the most distant γ-ray flaring blazar so far. Meanwhile, intraday optical variability of NVSS J163547+362930 is found based on an archival PTF/iPTF light curve. Benefiting from the multi-wavelength activity of these sources, constraints on their Doppler factors, as well as the locations of the γ-ray radiation region and indications for the SDSS high redshift jetted active galactic nuclei deficit are discussed.
Detection of Additional Be+sdO Systems from IUE Spectroscopy
Authors: Wang 王 Luqian 璐茜 , Gies Douglas R. , Peters Geraldine J. 
Published: February 2018

Abstract
There is growing evidence that some Be stars were spun up through mass transfer in a close binary system, leaving the former mass donor star as a hot, stripped-down object. There are five known cases of Be stars with hot subdwarf (sdO) companions that were discovered through International Ultraviolet Explorer (IUE) spectroscopy. Here we expand the search for Be+sdO candidates using archival FUV spectra from IUE. We collected IUE spectra for 264 stars and formed cross-correlation functions with a model spectrum for a hot subdwarf. Twelve new candidate Be+sdO systems were found, and eight of these display radial velocity variations associated with orbital motion. The new plus known Be+sdO systems have Be stars with spectral subtypes of B0–B3, and the lack of later-type systems is surprising given the large number of cooler B-stars in our sample. We discuss explanations for the observed number and spectral type distribution of the Be+sdO systems, and we argue that there are probably many Be systems with stripped companions that are too faint for detection through our analysis.
Dissipative Evolution of Unequal-mass Binary–single Interactions and Its Relevance to Gravitational-wave Detections
Authors: Samsing Johan , MacLeod Morgan , Ramirez-Ruiz Enrico 
Published: February 2018

Abstract
We present a study of binary–single interactions with energy-loss terms such as tidal dissipation and gravitational-wave (GW) emission added to the equation of motion. The inclusion of such terms leads to the formation of compact binaries that form during the three-body interaction through two-body captures. These binaries predominantly merge relatively promptly at high eccentricity, with several observable and dynamical consequences to follow. Despite their possibility for being observed in both present and upcoming transient surveys, their outcomes are not firmly constrained. In this paper, we present an analytical framework that allows to estimate the cross section of such two-body captures, which permits us to study how the corresponding rates depend on the initial orbital parameters, the mass hierarchy, the type of interacting object, and the energy dissipation mechanism. This formalism is applied here to study the formation of two-body GW captures, for which we estimate absolute and relative rates relevant to Advanced LIGO detections. It is shown that two-body GW captures should have compelling observational implications if a sizable fraction of detected compact binaries are formed via dynamical interactions.
The stoneflies (Insecta, Plecoptera) of the Talladega Mountain region, Alabama, USA: distribution, elevation, endemism, and rarity patterns
Authors: Grubbs Scott , Sheldon Andrew 
Published: February 2018

Background
The Talladega Mountain region of eastern Alabama is the southernmost outlier of the ancient Appalachian Mountains, including the highest peaks and ranges in the state. Collections of stoneflies (Plecoptera) previously here have been sporadic yet has led to several new species descriptions in modern times (James 1974, James 1976, Stark and Szczytko 1976, Kondratieff and Kirchner 1996, Szczytko and Kondratieff 2015) and expanded our understanding of southeastern US stoneflies. During the period 2003–2012 we conducted an intensive inventory of the stonefly fauna of the Talladega Mountain region. We collected across all months from 192 unique localities, covering a broad range of stream sizes and elevation gradients present in the region.
New information
A total of 57 confirmed species across eight of the nine Nearctic families were collected as adults (Table 4), including four species described as new during the study period (Table 2). Leuctra crossi James, 1974 was easily the most common species collected. Median elevations per species ranged from 174 m (Clioperla clio (Newman, 1839)) to 410 m (Leuctra triloba Claassen, 1923 (Fig. 3). Dot distribution maps were included for all 57 species plus one for undetermined nymphs of Pteronarcys Newman, 1838 (Figs. 4–19). As many as seven species may be endemic to the region but sampling efforts northeastward into Georgia, plus additional focused sampling in Alabama and a comprehensive examination of all available material held in museums and personal collections, are needed for confirmation.
Changing the Time of Blood Collection to Determine Vancomycin Concentrations in Intensive Care Unit Patients
Authors: Hammond Drayton A. , James Taylor B. , Atkinson Lexis N. , Painter Jacob T. , Lusardi Katherine 
Published: February 2018

BACKGROUND
Clinical practice guidelines for initiation and therapeutic drug monitoring, but not timing, of vancomycin dosing exist at many institutions. Scheduling vancomycin trough measurements and doses around the morning blood sample collection could yield more interpretable troughs and increase patient safety.

OBJECTIVE
To evaluate the appropriateness of blood sample collection times for vancomycin trough measurements before and after an initiative to change the timing of blood sampling to determine vancomycin doses and trough levels in a medical intensive care unit.

METHODS
A retrospective cohort study was conducted of patients in a medical intensive care unit who received intravenous vancomycin at a scheduled interval. Differences in continuous and categorical data were compared between pre- and postintervention groups. The primary outcome was proportion of blood samples collected for vancomycin trough measurements within 30 minutes of the next scheduled vancomycin dose.

RESULTS
Baseline characteristics were similar between the preintervention (n = 68) and postintervention (n = 176) groups except for the percentage of blood samples drawn for trough measurements and morning laboratory tests (6% vs 81%; P &lt; .001). Frequency of loading doses was similar between patients in the pre- and postintervention groups, as was weight-based maintenance dosing. There was no significant difference in the percentage of blood samples collected to measure vancomycin trough levels appropriately at 30, 60, or 75 minutes from the next scheduled dose.

CONCLUSION
Measuring vancomycin trough levels in morning blood samples did not affect the percentage of inappropriately collected blood samples used to measure vancomycin trough levels.
