Evaluation and revision of an introduction to experiential rotations course
Authors: Dy Eliza Anne , Nisly Sarah A 
Published: August 2014

ObjectiveThe objectives of this study were to evaluate the perceived student value of topics taught in a university’s Introduction to Experiential Rotations (RX500) course, implement course revisions to address any perceived weaknesses, and to reassess the course following implementation of those course revisions.MethodsAdvanced Pharmacy Practice Experience (APPE) students from the university’s 2012 doctorate of pharmacy class were initially surveyed to assess the perceived usefulness and design of RX500. Based on the findings of the initial data, course revisions were developed and implemented for the following semester’s RX500 course. In order to assess for potential changes in the perceived value of the course following implementation, a follow-up survey was sent to students completing the revised course in the fall of 2012.ResultsFifty-eight students completed the initial survey in the fall of 2011, and 34 completed the follow-up survey in the fall of 2012. The majority of students in the both groups had completed at least four APPE experiences at the time of survey completion. Both of the study groups rated hands-on activities and visual presentations as their most beneficial learning styles within a classroom setting. Based on the initial survey findings, two topics were removed from the course, two topics were revised within the course, and three topics were added to the course. The follow-up survey results indicated an increased perceived usefulness of the two revised topics; however, the three new topics added to the course had mixed results.ConclusionsData from the initial study period identified perceived areas for improvement in the course’s ability to prepare pharmacy students for the APPE year. Following course revisions based on student perceptions, follow-up surveys indicated improvements in the perceived values of the revised topics. Faculty can continue, however, to work on delivery of newer topics being added to the APPE preparation course.

Zusammfassung
Während Enterprise Social Software (ESS) zunehmend zum Einsatz kommt, stellt die Evaluierung ihres Nutzens immer noch eine Herausforderung für die meisten Unternehmen dar. Um ein besseres Verständnis für existierende Probleme zu entwickeln und Lösungsansätze zu finden, werden im vorliegenden Beitrag Barrieren der ESS-Erfolgsmessung auf Basis von 26 Experten-Interviews untersucht. Es werden 16 Barrieren identifiziert und in die Kategorien (1) Ressourcen und Verantwortlichkeit, (2) Ziele und Zieldefinition sowie (3) Vorgehen und Datenmaterial eingeordnet. Dabei zeigt sich, dass im Kontext von ESS insbesondere fehlende oder ungenaue Ziele die Erfolgsmessung erschweren und, dass der Erhebung von Nutzungsdaten eine höhere Bedeutung zukommt. Die anschließende Diskussion soll helfen, Potenziale zur Überwindung der Barrieren zu erkennen.
Discussion of the case of the missing heat
Authors: Parker Albert 
Published: August 2014

Abstract

The sea level projection of a 1 meter rise for the
21st century depends on climate models that have projected
a given amount of anthropogenic warming during
the same period. However, these same climate models predicted
a warming also from 2000 to 2014, which has not
been seen in the global surface temperature. Researchers
have proposed several solutions such as the fact that the
“missing heat” was accumulated in the deep ocean. However,
no evidences of a sufficient warming of the deep
oceans have been observed. Other arguments has been
proposed as well and found unsatisfactory. There is the
opportunity that the “heat” is not “real” but “missing” or
“hiding” somewhere. If the climate model projected “heat”
that simply does not exist in reality in the first place, consequently
the models overestimate the anthropogenicwarming
and also the sea level projections for the 21st century
are overestimated.
Natural frequency response of laminated hybrid composite beams with and without cutouts
Authors: Erkliğ Ahmet , Bulut Mehmet , Yeter Eyüp 
Published: August 2014

Abstract
This study deals with the effect of hybridization on the natural frequency of woven laminated hybrid composite beams with and without cutouts under the clamped-free boundary condition. Woven carbon, Kevlar and S-glass fibers with epoxy were used for the production of hybrid composites. Natural frequencies of the hybrid composite beams were experimentally determined for [(0/90)3]S stacking sequence. Numerical analyses were performed to investigate the influences of fiber orientation angles, circular and rectangular cutouts, cutout size ratios and positions on natural frequency. Good agreement between experimental and numerical results was found from a comparison of natural frequencies. The results shows that the fiber type used in the layers, cutout size and position on the beam strongly effects the natural frequency.
Nature of nano-sized plutonium particles in soils at the Hanford Site
Authors: Buck Edgar C. , Moore Dean A. , Czerwinski Kenneth R. , Conradson Steven D. , Batuk Olga N. , Felmy Andrew R. 
Published: August 2014

Abstract
The occurrence of plutonium dioxide (PuO2) either from direct
deposition or from the precipitation of plutonium-bearing solutions in
contaminated soils and sediments is well described, particularly for the
Hanford site in Washington State. However, past research has suggested that
plutonium at the Hanford site may exist in chemical forms in addition to
PuO2. Although the majority of the plutonium is present as oxide, we
present evidence for the formation of nano-sized mixed plutonium- iron
phosphate hydroxide structurally related to the rhabdophane group minerals
in 216-Z9 crib sediments from Hanford using both transmission electron
microscopy (TEM) and X-ray absorption spectroscopy (XAS). The iron-plutonium
phosphate formation may depend on the local microenvironment in the
sediments, availability of phosphate, and hence the distribution of these
minerals may control long-term migration of plutonium in the soil.

Published: August 2014

Los biomodelos utilizados para el estudio de la diabetes permiten evaluar factores genéticos y ambientales. Nuestro proósito fue caracterizar individuos de la línea de ratas genéticamente diabéticas eSS utilizando, mediante análisis multivariado, los valores de la curva de tolerancia lúcida y de glucosuria, junto con otras características fisiológicas y ambientales totalizando 9 variables. Se asignaron valores faltantes de glucosuria mediante un clasificador neuronal. Para la caracterizaci´´on de los individuos se aplicó el método de componentes principales y al efectuar la descripción de la estructura de los datos mediante representación gráfica en ejes factoriales, el primer eje separó los individuos según las glucemias, edad y peso y el segundo opuso la biomasa en edades tempranas con el tamaño de camada. El análisis en clusters definió una partición en 5 clases. Al relacionar los resultados con la clasificación clínica fue posible tipificar a los machos eSS desde los más jóvenes con menor peso, aglucosúricos, con glucemia de ayuno normal pero con alteración de la tolerancia a la glucosa hasta los diabéticos, de mayor peso y edad y glucosúricos, posibilitándose así la identificación de fases en la progresión del síndrome.
Sensor fusion using entropic measures of dependence
Authors: Deignan Paul B. 
Published: August 2014

As opposed to standard methods of association which rely on measures of central dispersion, entropic measures quantify multivalued relations. This distinction is especially important when high fidelity models of the sensed phenomena do not exist. The properties of entropic measures are shown to fit within the Bayesian framework of hierarchical sensor fusion. A method of estimating probabilistic structure for categorical and continuous valued measurements that is unbiased for finite data collections is presented. Additionally, a branch and bound method for optimal sensor suite selection suitable for either target refinement or anomaly detection is described. Finally, the methodology is applied against a known data set used in a standard data mining competition that features both sparse categorical and ontinuous valued descriptors of a target. Excellent quantitative and computational results against this data set support the conclusion that the proposed methodology is promising for general purpose low level data fusion.

Distribution des principales espèces agroforestières à Watinoma, terroir du Plateau Central burkinabé, une résultante de contraintes écologiques et anthropiques
Authors: Ouedraogo Sibiri Jean , Alexandre Daniel-Yves 
Published: August 2014

Watinoma est un village du Plateau Central burkinabé, situé à une centaine de
kilomètres au nord de la capitale, en zone soudano-sahélienne, dans la zone des roches vertes. La pluviométrie moyenne est de 600 mm et s'est réduit à 500 mm ces 20 dernières années. Dans ces conditions la végétation s'est contractée. Beaucoup d'arbres sont morts et les glacis dénudés se sont étendus. Les principales espèces du parc agroforestier montrent un comportement bien individualisé avec une opposition nette entre le karité et le Faidherbia qui traduit à la fois des caractères écologiques et ethnobotaniques (perception paysanne) contrastés. Faidherbia se rencontre dans deux types de situations : dans les bas-fonds sableux où la nappe phréatique existe et est accessible (présence de puits) et autour du village, en association avec le baobab et de nombreuses espèces exotiques, sur des sols argileux jeunes en contact avec la roche mère. Le karité est présent sur les sols sur cuirasse là où leur épaisseur dépasse 80 cm. Les sols plus minces portent d'autres espèces agroforestières dont le raisinier, le prunier et le kapokier rouge. La régénération de Faidherbia est abondante, surtout dans la zone du village, où les graines sont apportées avec les fumiers. Mais dans ces conditions les plants n'évoluent pas, d'une part parce que les conditions édaphiques ne sont pas favorables, d'autre part parce que les paysans les rabattent constamment.
La régénération du karité est, elle, peu abondante, limitée aux zones en jachère. Les paysans protègent les plants pourvu qu'ils soient suffisamment développés. Le néré serait aussi protégé si sa régénération existait, ce qui n'est plus le cas avec la sécheresse actuelle.
Observed and calculated gravity anomalies above a tunnel driven in clays – implication for errors in gravity interpretation
Authors: Blecha Vratislav , Mašín David 
Published: August 2014

ABSTRACTThe aim of this work was to evaluate the gravity effect of a deformation zone, which forms around subsurface cavities and to assess which method of density determination of soils in the surveyed area is optimal. We measured and modelled a gravity anomaly above a tunnel excavated in stiff clays. Technical parameters of the tunnel were known. The shape of the deformation zone around the tunnel was determined by geotechnical modelling. Material parameters of clays necessary for the geotechnical model were obtained from a measurement of borehole samples in a soil mechanics laboratory. For calculation of the gravity anomaly of the tunnel we used densities of clays derived from laboratory measurements of borehole samples. However, the fit between observed and calculated gravity data was not accurate in this case. The reason was probably that the volume and water content in the borehole clay samples changed after their removal from the depth. A better fit was obtained when we used densities derived from a gamma‐gamma well log. We found that the gravity effect of the deformation zone that forms around the tunnel in stiff clays is negligible (0.001 mGal). In our case, a concrete tunnel lining has a bigger influence on the amplitude of the anomaly than the deformation zone (0.008 mGal). When we neglect the lining in the interpretation, we obtain an error of 20% in the estimate of the tunnel depth.
3D inversion of magnetic data seeking sharp boundaries: a case study for a porphyry copper deposit from Now Chun in central Iran
Authors: Abedi Maysam , Gholami Ali , Norouzi Gholam‐Hossain 
Published: August 2014

ABSTRACTThis paper describes an application of 3D inversion of magnetic data to recover a susceptibility model from magnetic anomalies. For this purpose, the subsurface of the desired area of the magnetic anomaly is divided into a mesh with a large number of rectangular prisms with unknown susceptibilities. A Tikhonov cost function with multi‐term regularizers involving boundaries of susceptibility distribution and an edge‐preserving penalty function, as a tool to recover sharp boundaries, was used. Three methods (i.e., the U‐curve, Tikhonov‐curve and L‐curve methods) are applied to determine the optimum regularization parameter during the inversion process. Testing of the applied methods showed that the application of the U‐curve (a well‐known method in applied mathematics) in geophysical inverse problems and Tikhonov‐curve as a proposed technique can be appropriate candidates, like a common L‐curve method, for choosing the optimal regularization parameter. To avoid the natural tendency of magnetic structures to concentrate at the shallow depths in models created by inversion, a depth weighting function derived from information of the depth‐to‐the‐bottom of a generating source was applied. The AN‐EUL technique as a combination of the analytic signal and the Euler deconvolution methods is used to estimate the structural index of causative sources in order to construct an appropriate depth weighting function. Here, it is assumed that there is no remanent magnetization and the observed data are influenced by only the induced magnetization. A case study involving ground based measurements over a porphyry‐Cu deposit located in Kerman providence of Iran, Now Chun deposit, is included. The recovered 3D susceptibility model provided beneficial information for design of the exploration drilling programme. The susceptibility lows in the constructed model, in particular, their depths down to 410 m, coincides with the known locations of copper mineralization.

Objective To determine the prevalence of chromosomal abnormalities and microdeletions on Y chromosome in infertile patients with oligozoospermia or azoospermia in Mato Grosso state, Brazil. Methods This cross-sectional study enrolled 94 men from infertile couples. Karyotype analysis was performed by lymphocyte culture technique. DNA from each sample was extracted using non-enzymatic method. Microdeletions were investigated by polymerase chain reaction (PCR). Results With the use of cytogenetic analysis, five patients (5.3%) had abnormal karyotype, one azoospermic patient (1.1%) had karyotype 46,XY,t(7;1) (qter-p35), one (1.1%) with mild oligozoospermia had karyotype 46, XY, delY(q), and two other azoospermic patients had karyotype 47,XXY, consistent with Klinefelter syndrome (KS). One of them (1.1%) with severe oligozoospermia had karyotype 46,XY,8p+. Microdeletion on Y chromosome was found in the azoospermia factor c (AZFc) region in only one azoospermic patient (1.1%). Conclusions The prevalence of genetic abnormalities in oligo/azoospermic Brazilian men from infertile couple was 5.3%, and microdeletion on Y chromosome was not a common finding in this population (1.1%).

Published: August 2014

ABSTRACT

Objectives
Developmental odontogenic jaw cysts are generally connected with impacted or unerupted teeth. The conservative treatment options of these types of cysts will be presented.

Study design
In this study 17 cases operated in Süleyman Demirel and Selcuk Universities Faculty of Dentistry were included. The data of the cases were documented with respect to age, sex, localization, symptoms, presence of unerupted teeth on panoramic radiographs. The cysts were treated with marsupialization with an obturator made of acrylic resin in nine patients and a tube drain in eight patients to keep the window open.

Results and conclusion
Marsupialization was evaluated as extremely effective in 15 patients, the cysts completely disappeared and the permanent teeth were erupted, in two patients the cysts disappeared but the teeth were not erupted.
Enucleation, marsupialization or their combination are the conventional treatment options of the jaw cysts. Large cysts may localize nearby the important anatomical structures or may involve unerupted permanent teeth. These kind of cysts may be treated with marsupialization in order to protect these anatomical structures or to allow the eruption of the permanent teeth.
Marsupialization should be considered as an effective conservative treatment method of the jaw cysts during mixed dentition in the childhood.

Molar Incisor Hypomineralization
Authors: Bajwa Navroop Kaur , Jingarwar Mahesh Madhukar , Pathak Anuradha 
Published: August 2014

ABSTRACT
Developmental defects of tooth enamel are not uncommon, both in the primary and permanent dentition. An example of idiopathic enamel defect is molar incisor hypomineralization (MIH). The condition is defined as a hypomineralization of systemic origin of one to four permanent first molars frequently associated with affected incisors. The prevalence of MIH is reported to vary between 2.4 and 40.2% in normal child populations. Management consists of early diagnosis, prevention of caries or posteruptive breakdown and interception if caries or breakdown has already ensued. Management challenges include difficulty in obtaining adequate anesthesia, increased incidence of caries, early pulpal involvement and gross destruction of clinical crown of affected teeth. In young permanent teeth, semipermanent crowns like stainless steel crowns for posterior teeth and direct composite veneering for anterior teeth are the recommended solutions.

Published: August 2024

AbstractPurposeTo investigate the dose rate dependence of MapCHECK3 and its influence on measurement accuracy, as well as the effect of dose rate correction.Materials and methodsThe average and instantaneous dose rate dependence of MapCHECK2 and MapCHECK3 were studied. The accuracy of measurements was investigated where the dose rate differed significantly between dose calibration of the MapCHECK and the measurement. Measurements investigated include: the central axis dose for different fields at different depths, off‐axis doses outside the field, and off‐axis doses along the wedge direction. Measurements using an ion chamber were taken as the reference. Exponential functions were fit to account for average and instantaneous dose rate dependence for MapCHECK3 and used for dose rate correction. The effect of the dose rate correction was studied by comparing the differences between the measurements for MapCHECK (with and without the correction) and the reference.ResultsThe maximum dose rate dependence of MapCHECK3 is greater than 2.5%. If the dose calibration factor derived from a 10 × 10 cm2 open field at 10 cm depth was used for measurements, the average differences in central diode dose were 0.8% ± 1.0% and 1.0% ± 0.8% for the studied field sizes and measurement depths, respectively. The introduction of wedge would not only induce −1.8% ± 1.3% difference in central diode dose, but also overestimate the effective wedge angle. After the instantaneous dose rate correction, above differences can be changed to 1.9% ± 8.1%, 0.2% ± 0.1%, and 0.0% ± 0.9%. The pass rate can be improved from 98.4% to 98.8%, 98.3%–100.0%, and 96.3%–100.0%, respectively.ConclusionCompared with MapCHECK2 (SunPoint1 diodes), the more pronounced dose rate dependence of MapCHECK3 (SunPoint2 diodes) should be carefully considered. To ensure highly accurate measurement, it is suggested to perform the dose calibration at the same condition where measurement will be performed. Otherwise, the dose rate correction should be applied.
