Exact Traveling Wave Solutions to the (2 + 1)-Dimensional Jaulent-Miodek Equation

We derive exact traveling wave solutions to the (2 + 1)-dimensional Jaulent-Miodek equation by means of the complex method, and then we illustrate our main result by some computer simulations. It has presented that the applied method is very efficient and is practically well suited for the nonlinear differential equations that arise in mathematical physics.
Evolution and Systematic Value of Leaf Crystal Macropatterns in the Genus Peperomia (Piperaceae)

Leaves of Peperomia species vary in texture, shape, succulence, lamina size, thickness, coloration, and venation. Each leaf contains only calcium oxalate druses in palisade cells, druses in palisade and raphides in spongy parenchyma, or druses in palisade and prisms in spongy parenchyma. Collectively, these variations create distinct crystal macropatterns. Leaves from 45 species were studied to identify their macropatterns and to compare the macropatterns with molecular data. Microscopic data showed two major crystal macropatterns and five variations of them. All but one species displayed either a single druse in most palisade cells forming one or more uniform crystal layers (81.8%, uniform) or a single druse per cell in palisade cells only above veins forming a reticulate pattern (18.2%, reticulate). Most species (77.3%) did not display any crystals in spongy parenchyma; however, some clades showed spongy parenchyma raphide bundles while others had prisms. Several clades displayed more than one macropattern. Based only on crystal macropatterns, data did not demonstrate a specific phylogenetic trend and failed as synapomorphies for most of the clades. However, crystal macropattern evolution in Peperomia is generally characterized by an increasing complexity of the distribution of druses, raphides, and prisms, with few reversals.
The Effect of Feedback on Instructional Behaviours of Pre-Service Teacher Education.

Teacher training programs have a pivotal role in sophisticated Turkish education system. In order to reach high standards in teacher training, trainers should encourage and supervise pre-service teachers to use effective teaching skills and strategies. To ensure that providing feedback is regarded to be a widely accepted way for maximizing the use of teaching skills and strategies on newly established behaviours. With this in mind, the aim of this paper was to gain insights into the effects of immediate corrective feedback (delivered via a wireless FM listening system BIE) and delayed feedback on student teachers' instructional behaviours during instruction in teaching practicum. The research design is mixed-method sequential explanatory design. Thus, quantitative and qualitative researches were conducted respectively. Thirteen student teachers participated in the quantitative study and data was collected via a checklist. Out of thirteen student teachers, the semi-structured interviews were conducted with six student teachers for the qualitative phase. Immediate corrective feedback was found to be a more effective way than delayed feedback to help student teachers to be effective users of teaching practices such as class management, body language, voice level, use of intonation and stress, so forth. The findings were discussed and suggestions for further research were also addressed.
Two-phase numerical study of the flow field formed in water pump sump: influence of air entrainment

In a pump sump it is imperative that the amount of non-homogenous flow and entrained air be kept to a minimum. Free air-core vortex occurring at a water-intake pipe is an important problem encountered in hydraulic engineering. These vortices reduce pump performances, may have large effects on the operating conditions and lead to increase plant operating costs.This work is an extended study starting from 2006 in LML and published by ISSA and al. in 2008, 2009 and 2010. Several cases of sump configuration have been numerically investigated using two specific commercial codes and based on the initial geometry proposed by Constantinescu and Patel. Fluent and Star CCM+ codes are used in the previous studies. The results, obtained with a structured mesh, were strongly dependant on main geometrical sump configuration such as the suction pipe position, the submergence of the suction pipe on one hand and the turbulence model on the other hand. Part of the results showed a good agreement with experimental investigations already published. Experiments, conducted in order to select best positions of the suction pipe of a water-intake sump, gave qualitative results concerning flow disturbances in the pump-intake related to sump geometries and position of the pump intake. The purpose of this paper is to reproduce the flow pattern of experiments and to confirm the geometrical parameter that influences the flow structure in such a pump. The numerical model solves the Reynolds averaged Navier-Stokes (RANS) equations and VOF multiphase model. STAR CCM+ with an adapted mesh configuration using hexahedral mesh with prism layer near walls was used. Attempts have been made to calculate two phase unsteady flow for stronger mass flow rates and stronger submergence with low water level in order to be able to capture air entrainment. The results allow the knowledge of some limits of numerical models, of mass flow rates and of submergences for air entrainment. In the validation of this numerical model, emphasis was placed on the prediction of the number, location, size and strength of the various types of vortices coming from the free surface. Contours of vorticity at free surface, air cores, isoline of pressure surface were particularly examined for some cases. Streamlines issued from the free surface and the volume of fraction of air allows visualizing the air entrainment.
Problems in hard and soft matter: From brain folds and Levy localization to active elasticity

This thesis presents a study of condensed matter systems at di↵erent length scales. The first part presents a study of elastic instabilities in biological systems ranging from the cerebral cortex in the brain to the lining of the intestines. Such instabilities lead to a zoo of morphologies ranging from primary folds to villi and crypts to secondary folds and are brought about by growth, mechanical stresses, or a combination of the two. We propose a novel model for the description of primary folds in the cerebral cortex. Motivated by the spatial structure of the cortex, we model its elasticity as a smectic liquid crystal. With this novel description we show that vertical pulling forces via axonal tension from the brain underlying white matter can lead to buckling, which initiates the primary folds. Moreover, we are able to obtain a reasonable estimate of the critical wavelength and strain for buckling. We also model the formation of secondary folds in the cortex to obtain a more comprehensive theory. We continue this study of elastic instabilities due to growth by studying a more general system comprised of two coupled elastic membranes, one of which undergoes growth and one that does not. We employ an active formulation of growth and compare it to the one due to Rodriguez [1]. We show that di↵erent morphologies corresponding to di↵erent systems, such as the cerebral cortex and the lining of the intestines, can be obtained from our model by choosing di↵erent active stress functional forms to begin to classify the zoo of morphologies observed in seemingly di↵erent biological systems. In the second part of this thesis, to work towards a more microscopic view of biological tissues such as the brain tissue, which is composed of neurons, glial cells, and progenitor cells, we model an experiment [2] studying the dynamic interaction between neural crest cells and placodal cells in which the placodal cells run away from the neural crest cells following contact between the two. Our modeling contributes towards generalizing the rules governing the interplay between di↵erent cell types, particularly during collective cell migration. In the final part of this thesis, we move to an even smaller length scale. Our main motivations come from a series of experiments on the localization of light and the application of tight-binding models to the electronic transport properties of DNA sequences. To this end, we study the statistical properties of the conductance distribution and Lyapunov exponents in the Anderson tight-binding model with Levy-type disorder.

Dexmedetomedine-As an Adjuvant to Epidural Analgesia: Comparison Between Different Doses

Background: Epidural analgesia offers superior pain relief and early mobilization, especially when a local anesthetic [LA] dose is combined with an adjuvant vs. an LA alone. Objective: The current study compares the analgesic and anesthetic efficiency of dexmedetomidine (1 and 2 μgkg-1) and levobupivacaine, as well as their respective side effects. Materials and methods: This study was conducted on a total of 60 ASA I-II patients aged between 20 and 70 years, who underwent elective lower limb operations. The patients that received 1 μgkg-1 dexmedetomidine plus levobupivacaine were assigned to Group 1 (n=30) and those that received 2 μgkg-1 dexmedetomidine plus levobupivacaine to Group 2 (n=30). Results: Group 2 showed a significantly shortened onset time of sensory block, time needed for maximum sensory level and prolonged duration of anesthesia. Postoperatively, the total dose of levobupivacaine used was significantly lower, patients experienced a higher level of sedation and postoperative analgesia. However, Bradycardia and hypotension were more pronounced in Group 2 patients. Conclusion: Dexmedetomedine 2 μgkg-1 as an adjuvant to epidural analgesia significantly prolonged the duration of anesthesia and provided excellent sedation and postoperative analgesia. Therefore, higher doses of epidural dexmedetomedine are recommended in long surgical operations to avoid delayed motor recovery, bradycardia and hypotension.
The role of topography on catchment‐scale water residence time

The age, or residence time, of water is a fundamental descriptor of catchment hydrology, revealing information about the storage, flow pathways, and source of water in a single integrated measure. While there has been tremendous recent interest in residence time estimation to characterize watersheds, there are relatively few studies that have quantified residence time at the watershed scale, and fewer still that have extended those results beyond single catchments to larger landscape scales. We examined topographic controls on residence time for seven catchments (0.085–62.4 km2) that represent diverse geologic and geomorphic conditions in the western Cascade Mountains of Oregon. Our primary objective was to determine the dominant physical controls on catchment‐scale water residence time and specifically test the hypothesis that residence time is related to the size of the basin. Residence times were estimated by simple convolution models that described the transfer of precipitation isotopic composition to the stream network. We found that base flow mean residence times for exponential distributions ranged from 0.8 to 3.3 years. Mean residence time showed no correlation to basin area (r2 < 0.01) but instead was correlated (r2 = 0.91) to catchment terrain indices representing the flow path distance and flow path gradient to the stream network. These results illustrate that landscape organization (i.e., topography) rather than basin area controls catchment‐scale transport. Results from this study may provide a framework for describing scale‐invariant transport across climatic and geologic conditions, whereby the internal form and structure of the basin defines the first‐order control on base flow residence time.
The Effects of Argumentation Implementation on Environmental Education Self Efficacy Beliefs and Perspectives According to Environmental Problems

The purpose of this study is to investigate the effect of argumentation implementation applied in the environmental science course on science teacher candidates’ environmental education self-efficacy beliefs and perspectives according to environmental problems. In this mixed method research study, convergent parallel design was utilized. Quantitative part of this study was based upon one group pretest-posttest design. Qualitative part of this study was based upon holistic case study. The sample of the study consisted of 26 3 rd year science teacher candidates in A State University Education Faculty Science Education Department in the spring term of 2013-2014 academic years. The data collection tools were environmental education self-efficacy beliefs scale developed by Ozdemir, Aydin and Vural (2009) and drawings drawn by science teacher candidates to determine their perspectives on environmental problems. The experimental study took 7 weeks (21 hours). The first week involved the acquaintance with the students and briefing them about the study. Also, in this week, an educational plan related to the argumentation implementation was prepared and applied. And this week finally, scales were administered as pretest. The study started in the second week. The study took five weeks as three hours a week. Last week scales were administered as posttest. In quantitative data analysis paired samples t-test was used. For the analysis of qualitative data, categorical analysis technique, one of the content analysis techniques, was used. At the end of the study, it was observed that the science teacher candidates’ self-efficacy beliefs according to environmental education statistically differed in favor of the post-test. In addition, it was also found that, at the end of the study, science teacher candidates' perceptions of environmental problems differed according to their self-efficacy beliefs.
A comparison of dry and wet season aerosol number fluxes over the Amazon rain forest

Abstract. Vertical number fluxes of aerosol particles and vertical fluxes of CO2 were measured with the eddy covariance method at the top of a 53 m high tower in the Amazon rain forest as part of the LBA (The Large Scale Biosphere Atmosphere Experiment in Amazonia) experiment. The observed aerosol number fluxes included particles with sizes down to 10 nm in diameter. The measurements were carried out during the wet and dry season in 2008. In this study focus is on the dry season aerosol fluxes, with significant influence from biomass burning, and these are compared with aerosol fluxes measured during the wet season. Net particle deposition fluxes dominated in daytime in both seasons and the deposition flux was considerably larger in the dry season due to the much higher dry season particle concentration. The particle transfer velocity increased linearly with increasing friction velocity in both seasons. The difference in transfer velocity between the two seasons was small, indicating that the seasonal change in aerosol number size distribution is not enough for causing any significant change in deposition velocity. In general, particle transfer velocities in this study are low compared to studies over boreal forests. The reasons are probably the high percentage of accumulation mode particles and the low percentage of nucleation mode particles in the Amazon boundary layer, both in the dry and wet season, and low wind speeds in the tropics compared to the midlatitudes. In the dry season, nocturnal particle fluxes behaved very similar to the nocturnal CO2 fluxes. Throughout the night, the measured particle flux at the top of the tower was close to zero, but early in the morning there was an upward particle flux peak that is not likely a result of entrainment or local pollution. It is possible that these morning upward particle fluxes are associated with emission of primary biogenic particles from the rain forest. Emitted particles may be stored within the canopy during stable conditions at nighttime, similarly to CO2, and being released from the canopy when conditions become more turbulent in the morning.
Absorption, Translocation, and Metabolism of Picloram and 2,4-D in Leafy Spurge (Euphorbia esula)

The absorption, translocation, and metabolism of 14C-picloram and 14C-2,4-D applied alone and together to leafy spurge was evaluated. Leafy spurge absorbed 34 and 24% of the 14C-2,4-D applied alone and with picloram, respectively, and 14 and 10% of the 14C-picloram applied alone and with 2,4-D, respectively. More 14C-2,4-D was translocated in leafy spurge than 14C-picloram, and adding picloram to 14C-2,4-D decreased 14C translocation to the roots. Adding 2,4-D to 14C-picloram increased the percentage of absorbed 14C that translocated in leafy spurge from 28 to 48%. Generally, 14C-picloram and 14C-2,4-D remained as the parent acid in leafy spurge whether applied alone or together. Of 14C-picloram recovered from the roots, 83% was unmetabolized picloram when applied alone compared to 95% when applied with 2,4-D, which probably is the reason for increased leafy spurge control when these herbicides are applied together.
Skeletal Muscle Damage After Pitching Real Games in Collegiate Baseball Pitchers

Baseball pitchers are at risk for elbow and shoulder injuries. It is believed that many arm injuries in baseball pitchers result from cumulative microtrauma. The aim of this study was to investigate skeletal muscle damage after real games in Division I collegiate starting and relief pitchers. In order to examine the potential accumulation of muscle damage, the same procedure was performed in the beginning and end of a 3-month tournament. The first study included 4 starting pitchers and 5 relief pitchers. The second study included 3 starting pitchers and 5 relief pitchers. Plasma samples were collected the day before and 0 min, 30 min, 24 hr, 3 days, and 4 days after pitching a real game. For starting pitchers, plasma LDH was significantly increased immediately after pitching in the first study, and immediately and 30 min after in the second study. Plasma CK was significantly elevated immediately and 30 min after in the second study. For relief pitchers, LDH was significantly higher immediately after pitching in the second study. Plasma CK was unchanged in both studies. The pitching-induced muscle damage was similar between the 2 studies in both starting and relief pitchers. The results of this study indicated that starting pitchers may suffer the skeletal muscle damage after pitching a real game. However, the muscle damage appeared to be fully recovered within 24 hr. On the other hand, there was no significant muscle damage after pitching a real game in relief pitchers. In addition, a 3-month season did not result in accumulation of muscle damage in collegiate pitchers.
Development of a daily gridded precipitation data set for the Middle East

Abstract. We show an algorithm to construct a rain-gauge-based analysis of daily precipitation for the Middle East. One of the key points of our algorithm is to construct an accurate distribution of climatology. One possible advantage of this product is to validate high-resolution climate models and/or to diagnose the impact of climate changes on local hydrological resources. Many users are familiar with a monthly precipitation dataset (New et al., 1999) and a satellite-based daily precipitation dataset (Huffman et al., 2001), yet our data set, unlike theirs, clearly shows the effect of orography on daily precipitation and other extreme events, especially over the Fertile Crescent region. Currently the Middle-East precipitation analysis product is consisting of a 25-year data set for 1979–2003 based on more than 1300 stations.
Evidence of tuberculosis among children in medieval (13th–15th century) Wrocław: A case study of hip joint tuberculosis in a juvenile skeleton excavated from the crypt of the St. Elizabeth church

Abstract Paleopathological examinations of the skeletal remains of people who died centuries ago are material source of knowledge about health and diseases in the past. In this article, a case of skeletal tuberculosis from historical (13th-15th c.) Wrocław, Poland has been presented. The juvenile skeleton excavated from grave No 93, from the crypt located under the church of St. Elizabeth, displayed pathological lesions within the right hip joint resulting from a chronic inflammation, which might have been assigned to signs typical for skeletal tuberculosis. The results of macroscopic and radiological analyses appeared to be consistent, and allowed to determine a reliable diagnosis of this paleopathological case.
A Study on the Effect of Continuing Education with Digital Technology on Professional Growth and Job Satisfaction of Librarians

Digital technology and Internet have been combined with modern people’s life, and the combination of bit technology with network communication systems largely change people’s lifestyles. Along with the popularity of education, the application of digital technology also enhances the basic changes of learning methods and learning contents. To provide quality service, professional librarians are necessary for a library. Accordingly, librarians are the core management element of a library. In the changeable technology era, librarians need constant learning for self-growth through continuing education in order to cope with the changeable environment. Taking librarians of Shanghai University of Medicine & Health Sciences as the research object, the librarians are proceeded continuing education with digital technology, and the questionnaire is distributed and collected on-site after the continuing education. The research results show that 1.continuing education would significantly and positively affect professional growth, 2.professional growth would remarkably and positively affect job satisfaction, and 3.continuing education would notably and positively affect job satisfaction. With such results, suggestions are proposed, expecting to apply the professional curricula of continuing education with digital technology for the continuous growth of librarians in the changeable era, satisfying the enhancement of core competencies to cope with reader needs under the time and technology changes, and further promoting domestic librarians’ professional competence and the development of library business.
Signature of chaos and delocalization in a periodically driven many-body system: An out-of-time-order-correlation study

We study out-of-time-order correlation (OTOC) for one-dimensional periodically driven hardcore bosons in the presence of Aubry-Andr\'e (AA) potential and show that both the spectral properties and the saturation values of OTOC in the steady state of these driven systems provide a clear distinction between the localized and delocalized phases of these models. Our results, obtained via exact numerical diagonalization of these boson chains, thus indicate that OTOC can provide a signature of drive induced delocalization even for systems which do not have a well defined semiclassical (and/or large N) limit. We demonstrate the presence of such signature by analyzing two different drive protocols for hardcore bosons chains leading to distinct physical phenomena and discuss experiments which can test our theory.
