Comparison of heavy-metal bioaccumulation properties in Pinus sp. and Quercus sp. in selected European Cu deposits
Authors: Andráš Peter , Turisová Ingrid , Buccheri Giuseppe , de Matos João Manuel Xavier , Dirner Vojtech
Published: April 2016

Abstract. Heavy-metal contamination of Pinus pinaster, P. sylvestris, Quercus robur, and Q. rotundifolium was studied in four abandoned historic Cu deposits from Italy (Libiola, Caporciano), Portugal (São Domingos), and Slovakia (L'ubietová). The highest Cu and Mn contents in anthropogenic soil were described in Libiola and Caporciano whereas the highest Pb, Zn, As, and Sb contents in São Domingos. The anthropogenic soil in L'ubietová shows the highest Co contents. The area of São Domingos is the most acidified. There are important differences between the bioaccumulation of plants from individual deposits. Bioavailability of the heavy metals is generally independent of the pH values. The high Ca and Mg contents in soil are able to block the transport of heavy metals to the plant tissues. The bioconcentration factor values of all plant taxa, in all deposits, indicate a predominant strategy of excluders. Only Ag shows excellent bioconcentration ability. In L'ubietová, Pinus sylvestris has a strategy as an accumulator of Pb (2.43) and Zn (2.49); Pinus pinaster of Mn (4.97), Cd (1.85), and Co (5.62) and Quercus rotundifolium of Mn (3.54) in São Domingos. The predominantly low translocation factor values indicate that in most cases the heavy metals are accumulated in roots; only in a few rare cases do they migrate to shoots (e.g. Zn in Pinus sp. from all localities, Co in P. pinaster in São Domingos).
Teachers Application of the National Professional Standards in Three Northern Jordanian Provincial Schools
Authors: Alshurfat Saleh Swailem
Published: April 2016

The main purpose of this study was to explore and analyze primary school teachers'
perceptions at three Northern provinces about the application of national professional
standards for teachers. A questionnaire, which was based on the National Professional
Standards for Jordanian Teachers, was developed by a national and international team of
experts in (2006) as an integral part of the Jordanian educational reform program. The
questionnaire included seven scales containing (56) items. Participants were asked to respond
to each item statement using a five-point Likert scale. The study surveyed (632) teachers at
three Northern provinces. Both descriptive and inferential statistical procedures were
employed to analyze the data from the questionnaire survey. The main findings indicate that, in
general, teachers are moderately satisfied with their professional standards.

Authors: Bawalsah Joseph Awwad
Published: April 2016

This research aimed to investigate levels of stress in parents of children with disabilities in
Jordan, and coping strategies they used to handle these stresses. An Arabic translation of
Parental Stress Scale (Berry, & Jones, 1995) and Coping Strategies Inventory (Tobin, et al.,
1989) were used on a sample of 134 parents of children with physical, mental, and hearing
disabilities enrolled in diurnal special education centers. The results indicted high levels of
stress experienced by parents of children with disabilities; Parents of children with physical
disability tend to have the highest levels of stress, while parents of children with hearing
impairment have the lowest levels of stress. The results also showed that engagement coping
strategies were frequently more used in parents, with preference to use problem focused
engagement strategies more than emotion focused engagement strategies. In the other hand,
fathers of children with disabilities preferred to use engagement strategies more likely than
mothers who preferred disengagement strategies. And finally, the results indicated high
positive and significant correlation and acceptable predictable relation between levels of
stress and coping strategies.
Difficulties in Mastering and Using English for Specific Purpose (Medical Vocabulary): A Linguistic Analysis of Working Saudi Hospital Professionals
Authors: Khan Intakhab Alam
Published: April 2016

The prime aim and objective of this study was to explore and analyse the difficulties faced by the hospital professionals in knowing and using medical vocabulary (terms) in day to day professional life. It is generally known that English for Specific Purpose (ESP) is different from other general vocabulary courses in many ways. In order to carry out the study, subjects comprised 76 trainees who attended a professional development/training course on the medical terminology. The location of the training course was Jeddah (KSA) which was attended by four types of hospital professionals and trainees. Apart from the personal experience in the past and the current 30 hour-training, a self developed questionnaire was also used to elicit required data. The results of the survey indicated that most of the trainees faced difficulties due to: difficulties in English, Greek and Latin borrowing, difficult word-structure and lack of opportunities to practice. Based on the findings, it could be suggested that the learners should apply some strategies to pursue self-learning via web resource and peer learning.

Authors: Al Farah Jacoub , Bawalsah Joseph , Khateeb Bassam Al
Published: April 2016

This study aimed to investigate the impact of a training program based on Neuro Linguistic Programming (NLP) in the development of social communications skills among gifted six grade students in the city of Amman. The sample of the study consisted of (60) gifted students from sixth grade for the second semester of the academic year (2012/2013). The students were divided into two groups, the experimental group with (30) students and the control group with (30) students. To achieve the objectives of the study a training program based on NLP was designed with ten training sessions. The measure of social communication was applied and was prepared by researchers from the perspective of NLP on the experimental and control group as pre and post measure. After an appropriate statistical analysis, the results showed statistically significant differences in social communication skills between the experimental group and control group in favor of the experimental group. Students in the experimental group showed better level of possessions and use of social communication skills.  Depending on the results of the current study, the researchers have made a series of recommendations to take advantage of NLP in various fields of life.
Vietnamese EFL Students’ Perceptions of Noticing-Based Collaborative Feedback on Their Writing Performance
Authors: Dang Trang Thi Doan
Published: April 2016

It has been theoretically and empirically acknowledged that collaborative feedback is beneficial to learning achievement. However, feedback research remains relatively contentious due to learners’ differing viewpoints on how feedback is best given. Although a large number of studies have explored learners’ perspectives on collaborative feedback, little classroom-based research has promoted noticing through collaborative feedback. To address this, this study aims to infuse noticing-based collaborative correction into secondary classrooms to explore students’ perceptions of such feedback practice on their written output. Forty-one students’ responses to the list of close-ended questionnaires revealed a strong consensus about this potential approach although there are indications that the participants’ dependent learning styles had influenced these findings. An obvious implication of this is that students might benefit from various scaffolding sources, and thus there is a need for teachers to be aware of the influence of reciprocal learning among learners so that the quality of feedback practices may be enhanced.

Measurement of thermophysical property of plasma forming tungsten nanofiber layer
Authors: Kajita Shin , Yagi Takashi , Kobayashi Kenichi , Tokitani Masayuki , Ohno Noriyasu
Published: April 2016

Thermophysical property of a nanostructured tungsten layer formed on a tungsten film was investigated. A 1-µm-thick tungsten film deposited on a quartz glass substrate was irradiated with a high density helium plasma at the surface temperature of 1500 K. The plasma irradiation led to the formation of highly porous fiberform-nanostructured tungsten layer with a thickness of 3.5 µm. Impulse heating was applied at the interface of the film/substrate, and transient heat diffusion was observed using a pulsed light heating thermoreflectance apparatus. The thermoreflectance signals clearly differed between the nanostructure existing and mechanically removed regions; the difference can be attributed to thermal effusivity of the nanostructured tungsten layer. The estimated thermal conductivity of the nanostructured tungsten decreases to ∼2% of that of bulk when the density of the nanostructure is assumed to be ∼6% of the bulk value.
Sensitivity of Fermi level position at Ga-polar, N-polar, and nonpolar m-plane GaN surfaces to vacuum and air ambient

Published: April 2016

Ga-polar, N-polar, and nonpolar m-plane GaN UN+ structures have been examined in air and vacuum ambient by contactless electroreflectance (CER). This technique is very sensitive to the surface electric field that varies with the Fermi level position at the surface. For UN+ GaN structures [i.e., GaN (undoped)/GaN (n-type)/substrate], a homogeneous built-in electric field is expected in the undoped GaN layer that is manifested by Franz–Keldysh oscillation (FKO) in CER spectra. A clear change in FKO has been observed in CER spectra for N-polar and nonpolar m-plane structures when changing from air to vacuum ambient. This means that those surfaces are very sensitive to ambient atmosphere. In contrast to that, only a small change in FKO can be seen in the Ga-polar structure. This clearly shows that the ambient sensitivity of the Fermi level position at the GaN surface varies with the crystallographic orientation and is very high for N-polar and nonpolar m-plane surfaces. This feature of the N-polar and nonpolar m-plane surfaces can be very important for GaN-based devices grown on these crystallographic orientations and can be utilized in some of the devices, e.g., sensors.
Diffusion length measurements in GaN
Authors: Yakimov Eugene B.
Published: April 2016

The results of diffusion length measurements by fitting the collected current dependence on electron beam energy are discussed. It is shown that in GaN structures, this method also allows measuring the local dopant concentration. A possibility of diffusion length mapping by this method is demonstrated. It is shown that the dislocation density is too low to explain the small diffusion lengths measured in n-GaN.
Fine scale patterns of genetic partitioning in the rediscovered African crocodile,Crocodylus suchus(Saint-Hilaire 1807)
Authors: Cunningham Seth W. , Shirley Matthew H. , Hekkala Evon R.
Published: April 2016

Landscape heterogeneity, phylogenetic history, and stochasticity all influence patterns of geneflow and connectivity in wild vertebrates. Fine-scale patterns of genetic partitioning may be particularly important for the sustainable management of widespread species in trade, such as crocodiles. We examined genetic variation within the rediscovered African crocodile,Crocodylus suchus, across its distribution in West and Central Africa. We genotyped 109 individuals at nine microsatellite loci from 16 sampling localities and used three Bayesian clustering techniques and an analysis of contemporary gene flow to identify population structure across the landscape. We identified up to eight genetic clusters that largely correspond to populations isolated in coastal wetland systems and across large distances. Crocodile population clusters from the interior were readily distinguished from coastal areas, which were further subdivided by distance and drainage basin. Migration analyses indicated contemporary migration only between closely positioned coastal populations. These findings indicate high levels of population structure throughout the range ofC. suchusand we use our results to suggest a role for molecular tools in identifying crocodile conservation units for this species. Further research, including additional sampling throughout the Congo and Niger drainages, would clarify both the landscape connectivity and management of this species.

Published: April 2016

There is increasing emphasis from funding agencies on transdisciplinary approaches to integrate science and end‐users. However, transdisciplinary research can be laborious and costly and knowledge of effective collaborative processes in these endeavors is incomplete. More guidance grounded in actual project experiences is needed. Thus, this article describes and examines the collaborative process of the Ecological Effects of Sea Level Rise in the Northern Gulf of Mexico transdisciplinary research project, including its development, implementation, and evaluation. Reflections, considerations, and lessons learned from firsthand experience are shared, supported with examples, and connected to relevant scholarly literature.
The resolution dependence of cloud effects and ship‐induced aerosol‐cloud interactions in marine stratocumulus
Authors: Possner A. , Zubler E. , Lohmann U. , Schär C.
Published: April 2016

Measures of aerosol‐cloud interactions in stratocumulus have been shown to depend on the resolution of the applied data set. In order to contrast resolution with emission dilution effects in models, a regional numerical weather prediction model is used to simulate ship tracks at a range of spatiotemporal resolutions ranging from the global climate modeling scale (Δx = 50 km, Δt = 180 s) to the convection‐resolving scale (Δx = 1 km, Δt = 20 s). The background simulations without ship emissions display a high degree of similarity in the planetary boundary layer and cloud properties at all spatiotemporal resolutions. Simulations assessing the impact of emission dilution show an increasing overestimation of the shortwave (SW) cloud radiative effect (CRE) with degenerating emission resolution. Although mean perturbations in the activation‐sized aerosol number concentration (Nact) are similar for all dilution experiments, the variability in Nact is increasingly lost with stronger emission dilution. The enhanced Nact homogeneity in turn leads to an overestimated SW CRE. We show that emission dilution alone accounts for 47% of the overestimated SW CRE simulated at low resolutions. The remainder of the differences is attributed to a combination of locally enhanced aerosol concentrations due to weaker vertical mixing simulated at coarse resolutions, in combination with a faster conversion rate of Aitken to accumulation mode particles by redistribution in these regions.
Highly selective production of succinic acid by metabolically engineered Mannheimia succiniciproducens and its efficient purification

Published: April 2016

Succinic acid (SA) is one of the fermentative products of anaerobic metabolism, and an important industrial chemical that has been much studied for its bio‐based production. The key to the economically viable bio‐based SA production is to develop an SA producer capable of producing SA with high yield and productivity without byproducts. Mannheimia succiniciproducens is a capnophilic rumen bacterium capable of efficiently producing SA. In this study, in silico genome‐scale metabolic simulations were performed to identify gene targets to be engineered, and the PALK strain (ΔldhA and Δpta‐ackA) was constructed. Fed‐batch culture of PALK on glucose and glycerol as carbon sources resulted in the production of 66.14 g/L of SA with the yield and overall productivity of 1.34 mol/mol glucose equivalent and 3.39 g/L/h, respectively. SA production could be further increased to 90.68 g/L with the yield and overall productivity of 1.15 mol/mol glucose equivalent and 3.49 g/L/h, respectively, by utilizing a mixture of magnesium hydroxide and ammonia solution as a pH controlling solution. Furthermore, formation of byproducts was drastically reduced, resulting in almost homo‐fermentative SA production. This allowed the recovery and purification of SA to a high purity (99.997%) with a high recovery yield (74.65%) through simple downstream processes composed of decolorization, vacuum distillation, and crystallization. The SA producer and processes developed in this study will allow economical production of SA in an industrial‐scale. Biotechnol. Bioeng. 2016;113: 2168–2177. © 2016 Wiley Periodicals, Inc.
Design and demonstration of a pumpless 14 compartment microphysiological system
Authors: Miller Paula G. , Shuler Michael L.
Published: April 2016

We describe a human “Body‐on‐a‐chip” device (or microphysiological system) that could be used to emulate drug distribution, metabolism, and action in the body. It is based upon a physiologically based pharmacokinetic–pharmacodynamic (PBPK–PD) model, where multiple chambers representing different organs are connected with fluidic channels to mimic multi‐organ interactions within the body. Here we describe a pumpless 14 chamber (13 organs) microfluidic cell culture device that provides a separation between barrier and nonbarrier types of cell cultures. Our barrier chamber layer (skin, GI tract, and lung) allows for direct access and/or exposures to chemical or biological reagents forcing these reagents to pass through a barrier of cells established on a microfabricated membrane before exposing the nonbarrier tissue chambers (fat, kidney, heart, adrenal glands, liver, spleen, pancreas, bone marrow, brain, muscle) or entering the microfluidic circulation within the device. Our nonbarrier tissue chambers were created as three‐dimensional configurations by resuspending cells in hydrogel (PGMatrix). We used cell lines to represent five of these organs (barrier lines—A549 [lung] and Caco2 [GI]) (nonbarrier lines—HepG2 C3A [liver], Meg01 [bone marrow], and HK2 [kidney]). The dimensions of our straight duct‐like channels to each organ chamber were designed to provide the appropriate flow of a culture medium. The organ volumes and organ flow rates that have been reported for an average human male were used to estimate the desired fluid retention times in each organ chamber. The flow through the channels was induced by gravity on a custom programmed rocker platform which enabled pumpless operation and minimized bubble entrapment. The purpose of this paper is to describe the design and operation of a 14 chamber multi‐organ system representing 13 tissues/organs with both barrier and nonbarrier tissue chambers and to study the interactive responses among the various cell lines. We demonstrate that five different cell lines survived with high viability (above 85%) for 7 days. We compared the individual observed flow rates to the compartments to the desired or estimated flow rates. This work demonstrates the feasibility of constructing, operating and maintaining a simple, gravity‐driven, multi‐organ microphysiological system with the capability of measuring cellular functions such as CYP1A1 and CYP3A4 activities, albumin release, urea, maintenance of tight junctions, and presence of surfactant for a sustained period.

Published: April 2016

We employed UPLC‐MS/MS with iTRAQ 8‐plex labeling to quantitatively analyze the supernatant produced by two Chinese hamster ovary (CHO) cell lines (CHO K1SV and CHO CAT‐S). In each case, the supernatant from the host and three transfected clones were analyzed at days 5, 7, and 10 of culture. A total of eight iTRAQ 8‐plex experiments were performed. For each cell line, the overlap of supernatant protein identifications between transfected clones is over 60%. Over 70% of the supernatant proteins in the CHO K1SV host cell line are present in the CHO CAT‐S cell line. For the CHO K1SV cell line, the overlap in supernatant protein identifications between the host cell line and the transfected clones is >59%. For the CHO CAT‐S cell line, the overlap between supernatant protein identifications for the transfected clone and host cell is >45%. These differences in the supernatant protein identifications between transfected clones in each cell line and between the two host cell lines are not significant. We used cluster analysis to characterize the change in supernatant protein expression as a function of cell culture time. Roughly <60% of the supernatant proteins show significant change across the three time points (ratio >1.3 or <0.7). We also used cluster analysis to compare changes in supernatant protein expression between the host and three transfected clones at each time point. Greater than 65% of the common proteins in the CHO K1SV cell line supernatant and over 54% in the CHO CAT‐S cell line supernatant show no significant expression difference between host and the three transfected clones.

Optimizing cell seeding and retention in a three‐dimensional bioengineered cardiac ventricle: The two‐stage cellularization model
Authors: Patel Nikita M. , Yazdi Iman K. , Tasciotti Ennio , Birla Ravi K.
Published: April 2016

Current cell seeding techniques focus on passively directing cells to a scaffold surface with the addition of dynamic culture to encourage cell permeation. In 3D tissue engineered constructs, cell retention efficiency is dependent on the cell delivery method, and biomaterial properties. Passive cell delivery relies on cell migration to the scaffold surface; biomaterial surface properties and porosity determine cell infiltration capacity. As a result, cell retention efficiencies remain low. The development of an effective two‐stage cell seeding technique, coupled with perfusion culture, provides the potential to improve cellularization efficiency, and retention. This study, uses a chitosan bioengineered open ventricle (BEOV) scaffold to produce a two‐stage perfusion cultured ventricle (TPCV). TPCV were fabricated by direct injection of 10 million primary rat neonatal cardiac cells, followed by wrapping of the outer scaffold surface with a 3D fibrin gel artificial heart muscle patch; TPCV were perfusion cultured for 3 days. The average biopotential output was 1.731 mV. TPCV cell retention following culture was approximately 5%. Cardiac cells were deposited on the scaffold surface and formed intercellular connections. Histological assessment displayed localized cell clusters, with some dissemination, and validated the observed presence of intercellular and gap‐junction interactions. The study demonstrates initial effectiveness of our two‐stage cell delivery concept, based on function and biological metrics. Biotechnol. Bioeng. 2016;113: 2275–2285. © 2016 Wiley Periodicals, Inc.
