Hybridization between the unoccupied Shockley surface state and bulk electronic states on Cu(111)

Multi-photon photoemission, scanning tunneling spectroscopy and first-principles electronic structure calculations have been applied to determine the dispersion of the occupied and unoccupied Shockley surface state of Cu(111). The dispersion deviates significantly from the paradigmatic parabolic behavior of quasi-free electrons with increasing energy above the Fermi level. Based on our calculations, we ascribe this deviation to the shift of the spectral weight of the surface state into the bulk, and vice versa, which leads to an enhanced hybridization between the states with increasing energy.

Teachers’ Perception on the Functionality of the Introduced Cultural and Creative Arts Curriculum of the Nigerian Universal Basic Education

This study examined the perception of teachers on the functionality of the introduced Cultural and Creative Arts (CCA) curriculum of the Upper Basic Education (UBE) as it affects Music. In the study, a sample of 60 music teachers that teach CCA in UBE 1-3, derived from the six (6) educational zones in Anambra state was used. The instrument used for the study was a structured questionnaire containing test items arranged under competence, attitude, materials, managerial and methodology factors. Frequency, percentage and chi-square ( ) 2 χ statistical inference technique were the applied analytical tools for the study. The summary of the results obtained showed that those test items that are negatively affecting the introduction of CCA got 86.67%. Those test items that were positively affecting and those that were insignificant got 6.67% each. The identified factors impacting on the introduction of CCA were discussed in line with the results obtained, highlighting the problems and proffering possible solutions.
Role of Chemical Components of cork on Sorption of Aqueous Polycyclic Aromatic Hydrocarbons

In order to know the environmental behaviour of toxic pollutants it is fundamental to understandthe role of chemical components of a material on sorption of such pollutants.In this study, the sorption of amix of polycyclic aromatic hydrocarbons (PAHs) by cork fractions (i.e. raw cork (CF), free extractive cork(FEF) and nonsaponifiable (DESF)) has been investigated to better understand the role of biopolymers andextractable fraction of cork on their sorption behaviour. All samples were analyzed through elemental analysis and were examined using Fourier transform infrared spectroscopy. After removing the extractable fraction and the suberin from the cork, the sorption capacities (Koc) of FEF and DESF exhibited mean reductions of 70% and 30% respectively. In addition, the sorption results of three pairs of cork samples with different chemical content confirm that the extractable fraction serves as the major sorption medium for PAHs. Considering only low molecular weight PAHs positive correlations between Koc with Kow (R2=0.70) and F number (R2=0.65) were found, showing that these parameters are involved in this adsorption process.
From the emergency department to home.

AIM The purpose of this study was to explore dimensions of the management of the older person following care in an emergency department in preparation for discharge home by identifying perceptions and attitudes of staff in both emergency department and primary care sectors. BACKGROUND It is recognized that older people discharged home directly from the emergency department are a vulnerable group. Effective communication and liaison are seen to be keys to the provision of high quality care for older people in the emergency department and in ensuring a seamless care between sectors. DESIGN A purposeful sample was collected that comprised the total population (n = 222) of all grades of medical and nursing staff in both the emergency department and all nursing (Public Health Nurses & Practice nurses) and medical staff (General Practitioners) in the primary care area. METHODS Methodology used was that of a survey approach of nursing and medical staff in both the emergency department and primary care services. Standardized questionnaires were employed which comprised both open and closed questioning style. Raw statistical data were analysed using SPSS for Windows while the qualitative data arising from the open-ended questions were content analysed for themes. RESULTS Many staff in the primary care area reported the level of communication between the emergency department and the primary care area as unsatisfactory with confusion regarding follow-up care and a lack of support for older people on discharge. Hospital staff reported the level of communication to be much greater than that perceived by their colleagues in primary care. There was agreement of staff in both sectors in relation to the perceived usefulness of a discharge liaison nurse in the emergency department. CONCLUSIONS Previous research highlights communication difficulties when patients are discharged from hospital. Findings from this study indicate that this problem can also be applied to the emergency department. RELEVANCE TO CLINICAL PRACTICE Implications for practice include a need for a multidisciplinary approach to developing referral guidelines, staff training and a comprehensive dissemination of information between sectors ultimately to improve quality and continuity of care for the older person.
Genetic population structure of mangrove jack, Lutjanus argentimaculatus (Forsskål)

Translocations of mangrove jack, Lutjanus argentimaculatus (Forsskal 1775), to increase angling opportunities in artificial impoundments are foreshadowed in Queensland. To evaluate genetic population structure before translocations occur, mangrove jack were collected from three sites on the Queensland coast and from one site on the north-western coast of Western Australia. Allelic variation at four dinucleotide microsatellite loci was high: gene diversity (heterozygosity) ranged from 0.602 to 0.930 and allelic counts from 10 to 24. Genetic differentiation among collection sites was weak: estimates of FST were 0.002 for all four sites, and less (FST = 0.001) across a major biogeographical boundary (the Torres Strait region). Nucleotide sequence from two mitochondrial regions (control, 375 base pairs, and ATPase, 415 base pairs) was obtained from a subset of the Australian and additional Indo-Pacific (Indonesian and Samoan) mangrove jack. Haplotype diversity was high (control region, 33 haplotypes for 34 fish; ATPase region, 13 haplotypes for 56 fish). Phylogenetic analysis of mitochondrial DNA sequence data could not discern a relationship between tree topology and geography. These results suggest that mangrove jack in Queensland, and possibly throughout Australia, experience high levels of gene flow. The artificial gene flow caused by permitted translocations is unlikely to exceed natural levels. Fine-scale ecological matching between donor and recipient populations may increase stocking success, and is important if translocation is needed as a species recovery tool in the future.
Stapled haemorrhoidopexy — Complications and patient satisfaction *

Background: Surgical haemorrhoidectomy is recognised as an effective but often painful intervention for haemorrhoids. Performed in a district hospital setting, this survey studied the success rates of stapled haemorrhoidopexy (SH) technique according to reported symptoms and patient satisfaction, post operatively. Methods: A cohort of 108 patients admitted for circular stapled procedure at Inverclyde Royal Hospital between June 2006 and December 2011 gave their consent to be interviewed over the telephone after their procedure. 101 out of the 108 patients responded. Assessment of patient satisfaction was made on the basis of pre operative symptoms, postoperative results and complications. Results: Preoperatively, all patients had Grade lll or lV haemorrhoids complicated by haemorrhage. 33% of patients reported associated pain, and 25% complained of anal leakage. Mean follow up time was 23.8 months (7 38 months). Overall reported complication rate was 17%, with 9% reporting short term bleeding, 4% reporting shortlived post-operative pain and 3% with recurrence of prolapsed haemorrhoids. 88% of patients were happy with results, with 87% of patients happy to recommend the procedure to others. Conclusion: Stapled anopexy is a relatively new procedure. It has been found to be a successful and well-tolerated procedure for prolapsing haemorrhoids in this district general setting. It has a low recurrence rate, low incidence of post operative pain and a high level of patient satisfaction. However, there are associated complications and it has a steep training curve.
ASSEMBLAGE IN A SHALLOW LAKE

Shallow lakes are strongly affected by global climate changes reflected in significant parameters of ecosystem deterioration, i.e. biodiversity decrease, and water turbidity. Zooplankton research in Škrčev kut oxbow lake (Krapina River watershed, NW Croatia, Europe) was conducted during the summer of 2012 and 2013 with the aim to determine the effect of interannual, short-timescale changes of hydrological regime on environmental conditions, macrophytes, zooplankton and fish assemblage within an oxbow lake in the temperate region. Within one-year period the water level increased by 2 meters. This caused a significant reduction of floatingleaved macrophytes (i.e. Nuphar lutea), while turbidity, ortho-phosphate and chlorophyll a concentrations increased. These altered ecological conditions were reflected in the shift from floating-leaved macrophytes at the lower water level to phytoplankton-dominated lake at the higher water level. Zooplankton underwent significant alteration in assemblage. The results suggest that fish preference suppressed cladocerans and enhanced the rotifer and copepod abundance. Our results indicate that even in a short-timescale zooplankton assemblage mediates in the modification of ecosystem functioning.
An experimental study of wind force acting on commercial double-layered square metal screens at different spacing

In this study, an experimental setup was established to measure the pressure drop of flow through single- and double-layer woven metal screens. Three woven metal screens with different porosities of the plain-square type were tested in this study. The Reynolds number based on the screen wire diameter ranged from Re =111 to Re=2890 and the range of porosity was 0.34 to 0.67. Based on the measured drag coefficient of the three single- and double-layer plain woven metal screens, this study indicates the drag coefficient of low porosity double-layer screen is less than twice of that of the single-layer screen if the spacing of two layers remains less than 14 times of the screen wire diameter.
REMOVAL OF O,M,P-XYLENE FROM AIR SAMPLES ON OXIDIZED CARBON NANOTUBES CARTRIDGES

Carbon nanotubes (CNTs) have been considered as an excellent adsorbent in environmental engineering, especially for treatment of volatile organic compounds (VOCs). The paper presents a new approach for the selective adsorption of Xylene isomers from air samples using nanomaterial based on oxidized multiwalled carbon nanotubes. In the first study, the functionalization of two oxidized MWCNTs was achieved with hydrogen peroxide and sodium hypochlorite. The characterization of functionalized CNTs (CNT-NaOCl, CNT-H2O2) was performed by Fourier transform infrared spectroscopy (FT-IR) and X-Ray diffractometer (XRD). Afterthat, the applications of pristine CNTs and oxidized CNTs for removal of three Xylene isomers from air samples were discussed. The results demonstrate that the correlation of CNTs and three isomers was significantly different with an affinity order o-Xylene > m-Xylene > p-Xylene. The oxidized CNTs with carbonyl groups increased significantly its adsorption capacity for these isomers. A comparison in term of adsorption performance shows that the framework distinguishes among these adsorbents due to the dispersive properties and the electrostatic interaction between the Xylene isomers and oxidized CNTs surface.
Retrofitting of power lines effectively reduces mortality by electrocution in large birds: an example with the endangered Bonelli's eagle

Summary 1. Mortality caused by power lines is a conservation problem for many vulnerable bird species. Many large species are especially threatened by electrocution as they frequently perch on pylons leading to electrocution that typically causes death. Electrocution mitigation measures have been implemented to protect several species; however, a resulting decrease in mortality due to these measures has not previously been demonstrated at the population scale. 2. In this study, we used data from a long-term capture–recapture programme (combining resightings of live birds and recovery of dead birds) carried out on the French population of the Bonelli’s eagle Aquila fasciata from 1990 to 2009 to estimate the impact of the insulation of power lines on key demographic rates. 3. We found that the survival probability of all age classes increased after the insulation of dangerous power lines, due to a decrease in mortality caused by electrocution. This decrease was partially compensated for by an increase in other causes of death. 4. Our findings show that insulation of power lines has a strong positive impact on juveniles and immature birds and a lesser impact on adults. The overall increase in survival due to power line insulation led to a sharp increase in predicted population growth rates (from 082 to 098), although our findings still suggest that the population is not self-sustaining. Elasticity values indicate that adult survival is the key parameter in the population dynamics of this species, and since adult mortality caused by electrocution seemed close to zero, our ability to act on this parameter is limited. 5. This study demonstrates that insulation of power lines is relevant for the conservation of large bird species at a population scale as it allows the survival rate of all age classes to increase and thus in turn has a strong positive impact on population growth rates. 6. Synthesis and applications. We demonstrated that mortality rates induced by electrocution are considerable and have major consequences for the population viability of birds. We also demonstrated that electrocution mitigation measures can lead to a sharp increase in survival through reducing mortality from electrocution leading to improved population viability. In the light of these results, there is an urgent need that conservationists contact power line stakeholders not only to urge them to generalize retrofitting actions but also, in planning new infrastructure development, to plan for less harmful power lines, since this will be far less costly than developing a posteriori mitigation actions.
Relationship between Internal Quality Audit and Quality Culture toward Implementation Consistency of ISO 9000 in Private College of Sulawesi Province, Indonesia

The study aims to find out the influence of internal quality process on the growth of quality culture in private college. This study is treated toward 178 lecturers of 25 private colleges in Sulawesi, Indonesia by means of questionnaire. Confirmatory factor analysis applied to assess the reliability of validity and measurement model. Relationship between latent variable is checked by Structural Equation Modeling (SEM). This finding reveals the importance of facilitating personal involvement in organization and certainty toward implementation of job description in purpose to maximize the use of personal competence, wisdom, skill, and creativity. Simultaneous, multi-stage and systematic internal audit process will become forging experience for staffs, so it will form habits, beliefs, behavior, and attitude. The formation will bring changes of quality culture in private college. Sample is only taken from private college in Sulawesi, Indonesia and it does not involve state college. The finding may not be generalized for the other colleges. Hence, the further study is suggested to complete the gap. Considering the rise of quality assurance standard demand for college, then identification on factors which can grow up implementation consistency of quality management system is an urgent. Therefore, it is recommended that top management of college pay more attention to the process of internal quality audit systematically and continually. This paper explains factors affecting the growth of quality culture as the basis for implementation consistency of ISO 9000 quality management system in private college.
Research on Driver Behavior in Yellow Interval at Signalized Intersections

Vehicles are often caught in dilemma zone when they approach signalized intersections in yellow interval. The existence of dilemma zone which is significantly influenced by driver behavior seriously affects the efficiency and safety of intersections. This paper proposes the driver behavior models in yellow interval by logistic regression and fuzzy decision tree modeling, respectively, based on camera image data. Vehicle’s speed and distance to stop line are considered in logistic regression model, which also brings in a dummy variable to describe installation of countdown timer display. Fuzzy decision tree model is generated by FID3 algorithm whose heuristic information is fuzzy information entropy based on membership functions. This paper concludes that fuzzy decision tree is more accurate to describe driver behavior at signalized intersection than logistic regression model.
Arabic language efficacy questionnaire (ALEQ) : Assessing self-efficacy and achievement in Arabic language learning

Self-efficacy has long been a focus in language learning. Perceived as one's belief in his or her own capabilities in accomplishing a particular task, it affirms that personal behaviours, thoughts, beliefs and environmental conditions pose great impact on achievement. However, in Arabic language learning, research on self-efficacy is still at its infancy, what more of an instrument which precisely measures self-efficacy in Arabic language learning environment. Hence, this paper aims at verification of a newly-developed instrument, Arabic Language Efficacy Questionnaire (ALEQ), as well as to explore the relationship between self-efficacy and Arabic language achievement. A sample of 234 undergraduate students majoring in Arabic language was exposed to ALEQ, and a set of tests to determine their achievement in reading, writing and grammar. A principal components analysis with varimax rotation yields a 3-factor solution with satisfactory psychometric properties. The Pearson's r correlation analysis revealed a positive correlation between efficacy in reading, writing and grammar and students' achievement. Results clearly document that the ALEQ is a multidimensional measurement of Arabic language efficacy. It is concluded that although ALEQ has broad applicability, the scale herein may have relevance to the students' level of confidence in learning Arabic language and may be used in both research and teaching environments.
Modeling and simulation of transcriptional networks in murine cortical development

Conventional engineering is about design of systems that are completely defined within a limited range of operating conditions. The system’s blueprint is dawned in a top-down fashion by an external architect, and there is a clear distinction between construction phase and operational phase. Unlike explicit design, biological entities self-construct through the processes of development: structural and functional order result collectively from energy-dissipative processes involving cell replication and local interactions among cells or molecular components embedded in the physical environment. In this Thesis, I focus on a remarkable example of a self-constructing process, namely the development of the murine neocortex. The mouse neocortex is a highly organized structure composed of sheets of glial and neuronal cells characterized by great diversity in morphology, molecular expression profile and function. The elegant disposition of identifiable neural types into cortical laminae and their genetic characterization makes the cortex a convenient model to address the question of how such a diversity of cell types is generated. The novelty that I wish to present, is a hypothesis-generating method to study development, and corticogenesis in particular. In particular, I address three main aspects: (i) inference of transcriptional network models (in form of algorithmic rules) from sparse biological data during corticogenesis; (ii) the development of a formal description of gene regulatory rules consistent with biology; and (iii) the simulation of transcriptional networks for the generation of a laminated cortical column in Cortex3D, a Java agent-based software. At its core, development is the process by which multipotent progenitor cells undergo multiple rounds of symmetric and asymmetric cell divisions to finally produce differentiated cells with specific phenotypes, commonly referred to as terminal cell types. I describe this process at four different levels of abstraction, going from biological data to simulation of genetic control during development. At the first level of abstraction, insight into biological developmental programs is provided by the genealogical history of each precursor cell, the Cell Lineage Tree (CLT). Cell lineages are the key to understand development, since they describe the number of cells generated, the distribution of cell fates, and the topology or patterns of cell divisions. The collection of cell lineage data is technically challenging, therefore I relay on reconstructions from experimentally observed cell distributions. At the second level of abstraction, cell lineage data is described by a Markov Model with hidden states, where the characteristic features of a cell, and it’s daughter cells, are
Electronically Re-Configurable, Non-Volatile, Nano-Ionics-Based RF-Switch on Paper Substrate for Chipless RFID Applications

This article reports the first results of a Nafion®-based, solid state, non-volatile, electronically reconfigurable Radio Frequency (RF)-switch integrated to a co-planar waveguide transmission line (CPW) in shunt mode, on a flexible paper substrate. The switch is based on a metal–insulator–metal structure formed respectively using Silver–Nafion–aluminum switching layers. The presented device is fully passive and shows good performance till 3 GHz, with an insertion loss less than 3 dB in the RF-on state and isolation greater than 15 dB in the RF-off state. Low-power direct current pulses in the range 10 V/0.5 mA and −20 V/0.15 A are used to operate the switch. The device was fabricated in an ambient laboratory condition, without the use of any clean room facilities. A brief discussion of the results and potential application of this concept in a re-configurable chipless RFID tag is also given in this article. This study is a proof of concept of fabrication of electronically re-configurable and disposable RF-electronic switches on low cost and flexible substrates, using a process feasible for mass production.
Endangerment of fir stands by root infection diseases beyond fir natural occurrence reach

From the area of West Pomerania, there are no reports referring to mycological studies connected with tree stands dominated by fir or spruce infested by dangerous root pathogens. The purpose of this introduction was to verify whether fir stands beyond the borders of their natural reach are threatened by Heterobasidion sp. and Armillaria sp. Studies were carried out on three research areas in the survey units: 244 b and 225 kx of the Forest District Oszusznica. From the sampled wood, 10 isolates of Armillaria sp. and 21 isolates of Heterobasidion sp. were obtained. The analysis of results obtained during the presented studies permits to state definitely that the tree stands in 244 b and 244 kx subcompartments show a good state of health). An interesting scientific report is the statement of occurrence, on the area covered by the presented studies, of the species Hete- robasidion annosum of S type which has not been reported so far from West Pomerania.
