Technical and economic performance analysis of large‐scale ground‐mounted PV plants in Italian context
Authors: Aste N. , Del Pero C. 
Published: April 2010

AbstractDuring the last decade, the market penetration of photovoltaic (PV) technology has been increased tremendously worldwide. In the EU context, following the quick development in German and Spanish PV sector, Italy is currently one of the most interesting market. In view of these facts, it is strategic to perform detailed technical and economic analyses to establish energy performances and profitability of the PV plants, depending on their configurations. In particular, in addition to the selection of main components, such as inverters and modules, which are now characterized, on average, by good performance levels, the debate on the support structures is still open. In detail, the choice may fall, for example, on traditional fixed structures or on one/two axis tracking systems, that could ensure best productivity per unit of power, but also are typically characterized by higher complexity and land‐occupation factors than the first ones. The purpose of this work is to carry out performance analyses on the most widespread plant configurations, taking into account different Italian climatic contexts, considering technical, energetic, and economic points of view. With this aim, different types of components (modules and inverters) and ground‐mounting structures (fixed, one‐axis, two‐axis) have been evaluated. Subsequently, their obtainable performances have been estimated in three different locations (Milano, Roma, Palermo) that have been considered representative of average irradiation levels available in Italy. Analyses have been carried out by computer simulations, through two consequent levels of detail, highlighting the main performance influence‐factors. In conclusion, the final profitability of each analyzed configuration has been evaluated, giving a reliable indication on their effective economic advantages. Copyright © 2010 John Wiley & Sons, Ltd.
Two‐dimensional reference map for the basic proteome of the human dorsolateral prefrontal cortex (dlPFC) of the prefrontal lobe region of the brain
Authors: McManus Ciara A. , Polden Julie , Cotter David R. , Dunn Michael J. 
Published: April 2010

AbstractWe describe a 2‐DE proteomic reference map containing 227 basic proteins in the dorsolateral prefrontal cortex region of the human brain. Proteins were separated in the first dimension on pH 6–11 IPG strips using paper‐bridge loading and on 12% SDS‐PAGE in the second dimension. Proteins were subsequently identified by MS and spectra were analyzed using an in‐house proteomics data analysis platform, Proline. The 2‐DE reference map is available via the UCD 2‐DE Proteome Database (http://proteomics‐portal.ucd.ie:8082) and can also be accessed via the WORLD‐2DPAGE Portal (http://www.expasy.ch/world‐2dpage/). The associated protein identification data have been submitted to the PRIDE database (accession numbers 10018–10033). Separation of proteins in the basic region resolves more membrane associated proteins relevant to the synaptic pathology central to many neurological disorders. The 2‐DE reference map will aid with further characterisation of neurological disorders such as bipolar and schizophrenia.
EZYprep LC‐coupled MALDI‐TOF/TOF MS: An improved matrix spray application for phosphopeptide characterisation

Published: April 2010

AbstractThe quality of MALDI‐TOF mass spectrometric analysis is highly dependent on the matrix and its deposition strategy. Although different matrix‐deposition methods have specific advantages, one major problem in the field of proteomics, particularly with respect to quantitation, is reproducibility between users or laboratories. Compounding this is the varying crystal homogeneity of matrices depending on the deposition strategy used. Here, we describe a novel optimised matrix‐deposition strategy for LC‐MALDI‐TOF/TOF MS using an automated instrument that produces a nebulised matrix “mist” under controlled atmospheric conditions. Comparisons of this with previously reported strategies showed the method to be advantageous for the atypical matrix, 2,5‐DHB, and improved phosphopeptide ionisation when compared with deposition strategies for CHCA. This optimised DHB matrix‐deposition strategy with LC‐MALDI‐TOF/TOF MS, termed EZYprep LC, was subsequently optimised for phosphoproteome analysis and compared to LC‐ESI‐IT‐MS and a previously reported approach for phosphotyrosine identification and characterisation. These methods were used to map phosphorylation on epidermal growth factor‐stimulated epidermal growth factor receptor to gauge the sensitivity of the proposed method. EZYprep DHB LC‐MALDI‐TOF/TOF MS was able to identify more phosphopeptides and characterise more phosphorylation sites than the other two proteomic strategies, thus proving to be a sensitive approach for phosphoproteome analysis.

Published: April 2010

AbstractObjective: Although a variety of intervention methods have been used to promote Pap test screening among ethnic minority women in the US, the effectiveness of such interventions is unclear. We performed a meta‐analysis to examine the overall effectiveness of these interventions in increasing Pap test use by ethnic minority women in the US.Methods: A search of databases (MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and Science Citation Index‐Expanded) and review articles for articles published between 1984 and April 2009 identified 18 randomized and non‐randomized controlled trials. The primary study outcome was the difference in the proportion of Pap tests between the treatment and comparison groups.Results: The pooled mean weighted effect size (d) for the 18 studies was 0.158 (95% confidence interval [CI]=0.100, 0.215), indicating that the interventions were effective in improving Pap test use among ethnic minority women. Among the intervention types, access enhancement yielded the largest effect size (0.253 [95% CI=0.110, 0.397]), followed by community education (0.167 [95% CI=0.057, 0.278]) and individual counseling or letters (0.132 [95% CI=0.069, 0.195]). Combined intervention effects were significant for studies targeting Asian (0.177 [95% CI=0.098, 0.256]) and African American women (0.146 [95% CI=0.028, 0.265]), but not Hispanic women (0.116 [95% CI=−0.008, 0.240]).Conclusions: Pap test use among ethnic minority women is most likely to increase when access‐enhancing strategies are combined. Further research is needed to determine whether more tightly controlled trials of such interventions might reveal an improved rate of cervical cancer screening in Hispanic women as well.

Published: April 2010

AbstractThe research on ZnO has a long history but experiences an extremely vivid revival during the last 10 years. We critically discuss in this didactical review old and new results concentrating on optical properties but presenting shortly also a few aspects of other fields like transport or magnetic properties. We start generally with the properties of bulk samples, proceed then to epitaxial layers and nanorods, which have in many respects properties identical to bulk samples and end in several cases with data on quantum wells or nano crystallites. Since it is a didactical review, we present explicitly misconceptions found frequently in submitted or published papers, with the aim to help young scientists entering this field to improve the quality of their submitted manuscripts. We finish with an appendix on quasi two‐ and one‐dimensional exciton cavity polaritons.
Dipolar vibrational modes confined in ZnSe nanocrystals
Authors: Belogorokhov Alexander , Belogorokhova Liubov , Gavrilov Sergei 
Published: April 2010

AbstractOptical phonons confined in highly monodisperse and nearly spherical ZnSe quasi‐zero‐dimensionals (QDs) produced in the form of a colloidal solution in porous matrix have been studied experimentally and theoretically. Far‐infrared transmission spectra and Raman spectra show a broad band between the bulk transverse optical (TO) and longitudinal optical (LO) phonon frequencies. The data are discussed by calculating the frequencies of the spatially quantized phonon modes in the framework of a continuum model.
Sustainable coastal development and open planning? Transferring the integrated area approach to Bulgaria
Authors: Dieperink Carel , Boesten Rene , Hovens Jeroen , Tonkes Henrieke 
Published: April 2010

AbstractSustainable development asks for open planning processes. Such open planning processes have become common practice in the Netherlands and other Western countries. Since EU accession, new member states such as Bulgaria also have to face the challenge of organizing more open planning processes in their search for a more sustainable future. The aim of this article is to reflect on the opportunities for and barriers to open planning processes in the Bulgarian context by assessing the results of the MyCoast project. The MyCoast project is an attempt to transfer the Dutch experiences with open planning processes to Bulgaria. The project aims to involve stakeholders in the development of a vision and strategy for a more sustainable Black Sea coastal zone. Our research revealed that the MyCoast project approach appeared to be completely new for the Bulgarian stakeholders involved and that several preconditions for success had yet to be met. The paper therefore concludes with some recommendations to enhance the opportunities for more open planning approaches in Bulgaria and other countries.

AbstractBuilding sustainability knowledge on the web is a vital path towards surpassing the barriers that could hinder sustainable development in any country in general. This paper presents the results of examining digital sustainability knowledge in the Arab world. A thorough examination and statistical analysis were performed on sustainable development websites that exist in all Arab countries during a specific period of time. The Global System for Sustainable Development (GSSD) is the knowledge management system used to store the sustainability knowledge in the region. The system is designed to be used by decision makers, scientists, educators and knowledge seekers. The main strength of the system is that it points users to needed knowledge on sustainable development that exists on the web. The search engine is the main driver and speakers of different languages can use it. Results indicate that most of the Arab countries have the same sustainable knowledge profile by showing existing problems and not solutions. Most of the information deals with issues related to wars and conflicts, migration and dislocation, and unmet basic needs, which reflect the political and social situation in many Arab countries. The paper concludes with some recommendations on how to improve sustainability knowledge on the web in the region. Copyright © 2010 John Wiley & Sons, Ltd and ERP Environment.

Authors: Socha Robert P. , Zackiewicz Ewa , Spiridis Nika , Korecki Józef 
Published: April 2010

AbstractThe XPS technique was applied to study Au deposition on defect‐rich MgO(100) surfaces in a coverage range of 0.2–5 Au monolayers. Three MgO surfaces were used with increasing concentration of surface defects as determined based on surface composition and modified Auger parameter: air‐cleaved, ultrahigh‐vacuum‐cleaved, and polished. The analysis of the Au 4f core excitation intensities showed 3D‐island growth of Au. The Au 4f binding energy was shown to decrease with increasing Au coverage, with a dependence on the substrate type. Copyright © 2010 John Wiley & Sons, Ltd.

Authors: Branzoi I. V. , Iordoc M. , Branzoi F. , Vasilescu‐Mirea R. , Sbarcea G. 
Published: April 2010

AbstractThe aim of this study is to modify the surface of Nitinol (Nickel Titanium Naval Ordnance Laboratory) alloy by covering with diamond‐like carbon to improve the corrosion resistance and biocompatibility, and to prevent the toxic nickel ion release inside the human body. This alloy has unique properties, including shape memory effect and super elasticity, which make it an attractive candidate for biomedical applications. Diamond‐like carbon (DLC) films were deposited by d.c. magnetron sputtering using a graphite target and argon as the discharge gas. The electrochemical characteristics of the DLC coatings were investigated by electrochemical techniques (potentiodynamic polarization test and electrochemical impedance spectroscopy) at 37 °C in Fetal Bovine Serum (FBS). Surface analysis of the DLC coatings was conducted by means of X‐Ray Diffraction (XRD), SEM and Vickers microhardness, and the thickness of DLC layer was measured using interferometry technique. The metallic ions release in bulk solution was studied by inductive coupling plasma‐mass spectrometry (ICP‐MS). In the case of uncoated samples, the release of metallic ions in bulk solution was much higher than in the case of DLC coated samples. Also, the corrosion resistance and Vickers microhardness of DLC‐coated samples were improved in comparison with the uncoated samples. Copyright © 2010 John Wiley & Sons, Ltd.

Published: April 2010

AbstractSocial software has received much attention in the academia and industry due to many success stories. However, although social software is used widely for business support, its relationship with Business Process Management has not been analysed. The results of the workshop on Business Process Management and Social Software (BPMS2'08), as part of the International Conference on Business Process Management in Milano, show the manifold possibilities of combining concepts from Business Process Management and social software. Social software provides a better integration of all stakeholders into the business process life cycle and offers new possibilities for a more effective and flexible design of business processes. The modelling of business processes may profit particularly from using social software techniques by alleviating the integration of process knowledge from all stakeholders. In addition, the implementation and deployment phase of the business process life cycle may profit from social software by collecting valuable information for continuous process improvement from a larger set of sources than before. Furthermore, social software environments may be used to provide workflow support. Moreover, the use of social software also requires new considerations about the digital identity and reputation in business processes. Copyright © 2010 John Wiley & Sons, Ltd.

Published: April 2010

AbstractThe effect of polyaniline and polypyrrole composites and the influence of type and concentration of stabilizer, pH of solution, and type of adsorbent on lead salt removal from aqueous solution were studied. The results indicated that the extents of removal of lead in alkaline solution (pH = 10) were 99.95 and 99.23%, respectively, when polyaniline and Polyaniline/(sodium dodecylbenzenesulfonate) composite were used as adsorbents. The results were compared with those obtained by using cation exchangers such as Purolite and Amberjet, and the observations indicated that Purolite and Amberjet were the better lead removal agents.

Cross‐layer design for topology control and routing in MANETs
Authors: Ghada Khoriba , Li Jie , Ji Yusheng 
Published: April 2010

AbstractA mobile ad hoc network (MANET) is a self‐organized and adaptive wireless network formed by dynamically gathering mobile nodes. Since the topology of the network is constantly changing, the issue of routing packets and energy conservation become challenging tasks. In this paper, we propose a cross‐layer design that jointly considers routing and topology control taking mobility and interference into account for MANETs. We called the proposed protocol as Mobility‐aware Routing and Interference‐aware Topology control (MRIT) protocol. The main objective of the proposed protocol is to increase the network lifetime, reduce energy consumption, and find stable end‐to‐end routes for MANETs. We evaluate the performance of the proposed protocol by comprehensively simulating a set of random MANET environments. The results show that the proposed protocol reduces energy consumption rate, end‐to‐end delay, interference while preserving throughput and network connectivity.

The resource regulation hypothesis and positive feedback loops in plant–herbivore interactions
Authors: Craig Timothy Paul 
Published: April 2010

AbstractResource regulation occurs when herbivory maintains or increases plant susceptibility to further herbivory by the same species. A review of the literature indicates it is a widespread plant–animal interaction involving a diverse array of herbivores. At least three mechanisms can produce this positive feedback cycle. First, phytophagous insect and mammalian herbivore damage can stimulate dormant buds to produce vigorous juvenile growth, which is preferred for further attack. Juvenilization cycles may have repeatedly evolved because herbivores are able to take advantage of a generalized plant compensatory response to any type of damage. Second, herbivores can manipulate plant source–sink relationships to attain more resources, and this alteration of plant growth may benefit subsequent herbivore generations. Third, herbivory can alter plant nutrition or defensive chemistry in a way that makes a plant susceptible to more herbivory. Resource regulation probably occurs because damage to resources preferred by the herbivores induces a generalized plant response that produces more preferred resources. Alternatively, manipulation of plant resources to induce resource regulation may have evolved in herbivores with a high degree of philopatry due to selection to alter plant resources to benefit their offspring. Resource regulation can stabilize insect population dynamics by maintaining a supply of high‐quality plant resources. It can also increase the heterogeneity of host‐plant resources for herbivores by altering the physiological age structure and the distribution of resources within plants. Resource regulation may have strong plant‐mediated effects on other organisms that use that host plant, but these effects have not yet been explored.
Sets of determination and kernels of certain associated operators
Authors: Stray Arne 
Published: April 2010

AbstractLet m be a measure supported on a relatively closed subset X of the unit disc. If f is a bounded function on the unit circle, let fm denote the restriction to X of the harmonic extension of f to the unit disc. We characterize those m such that the pre-adjoint of the linear map f → fm has a non-trivial kernel.
Centre manifold variety for eight-parameter families of polynomial vector fields of arbitrary degree

A new construction of the Ree groups of type 2G2
Authors: Wilson Robert A. 
Published: April 2010

AbstractWe give a new elementary construction of Ree's family of finite simple groups of type 2G2, which avoids the need for the machinery of Lie algebras and algebraic groups. We prove that the groups we construct are simple of order q3(q3 + 1)(q − 1) and act doubly transitively on an explicit set of q3 + 1 points, where q = 32k+1. Moreover, our construction is practical in the sense that generators for the groups and many of their maximal subgroups may easily be obtained.

From permutahedron to associahedron
Authors: Brady Thomas , Watt Colum 
Published: April 2010

AbstractFor each finite real reflection group W, we identify a copy of the type-W simplicial generalized associahedron inside the corresponding simplicial permutahedron. This defines a bijection between the facets of the generalized associahedron and the elements of the type-W non-crossing partition lattice that is more tractable than previous such bijections. We show that the simplicial fan determined by this associahedron coincides with the Cambrian fan for W.
The Ultrametric Corona Problem and spherically complete fields
Authors: Escassut Alain 
Published: April 2010

AbstractLet K be a complete ultrametric algebraically closed field and let A be the Banach K-algebra of bounded analytic functions in the ‘open’ unit disc D of K provided with the Gauss norm. Let Mult(A,‖ · ‖) be the set of continuous multiplicative semi-norms of A provided with the topology of simple convergence, let Multm(A, ‖ · ‖) be the subset of the φ ∈ Mult(A, ‖ · ‖) whose kernel is a maximal ideal and let Multa(A, ‖ · ‖) be the subset of the φ ∈ Mult(A, ‖ · ‖) whose kernel is a maximal ideal of the form (x − a)A with a ∈ D. We complete the characterization of continuous multiplicative norms of A by proving that the Gauss norm defined on polynomials has a unique continuation to A as a norm: the Gauss norm again. But we find prime closed ideals that are neither maximal nor null. The Corona Problem on A lies in two questions: is Multa(A, ‖ · ‖) dense in Multm(A, ‖ · ‖)? Is it dense in Multm(A, ‖ · ‖)? In a previous paper, Mainetti and Escassut showed that if each maximal ideal of A is the kernel of a unique φ ∈ Mult(m(A, ‖ · ‖), then the answer to the first question is affirmative. In particular, the authors showed that when K is strongly valued each maximal ideal of A is the kernel of a unique φ ∈ Mult(m(A, ‖ · ‖). Here we prove that this uniqueness also holds when K is spherically complete, and therefore so does the density of Multa(A, ‖ · ‖) in Multm(A, ‖ · ‖).
