Olive Tree's Pruning Harvesting Using the Greek Modified Mulcher Fotopoulos FSR2000, Machine Performances and Biomass Quality Evaluation
No full textHarvesting is a key stage that influences the product quality, the type of logistics chain and the economic sustainability of the pruning supply chain. For this reason many machine manufacturers have developed dedicated implements for collecting pruning residues. According to what written above the selection of an appropriate harvesting systems, and so an accurate evaluation of different suitable machines, is a fundamental step to the correct development of a complete and efficient pruning supply chain.
Thus the aim of the present study was machine performances and biomass quality evaluation in olive trees’ pruning harvesting conducted with Fotopoulos FSR2000
Spatial Variations in New Manufacturing Plant Openings: Some Empirical Evidence from Greece
No full textFOTOPOULOS G. and SPENCE N. (1999) Spatial variations in new manufacturing plant openings: some empirical evidence from Greece, Reg. Studies 33 , 219-229. This research deals with the determinants of regional variation in new plant openings in Greek manufacturing industries over the period 1980-91. Key findings of this first detailed attempt to do so in a Greek context relate to the significant direct effects of regional specialization, the extent of local production links and investment in public infrastructure on new manufacturing activity. Confirming research findings in other countries, the results obtained here indicate small firm presence, the local supply of skilled labour, and wealth and labour productivity differentials across regions to be significant and positive influences on new firm formation.

Olive Tree's Pruning Harvesting Using the Greek Modified Mulcher Fotopoulos FSR2000, Machine Performances and Biomass Quality Evaluation
No full textPruning’s residues could be an important source for renewable energy production. However their use for this aim is actually hindered by various fences mainly linked to the lacking in harvesting phases and to the absence of a sustainable logistic chain for energy production. Considering this the AGROinLOG (Demonstration of innovative integrated biomass logistics centres (IBLC) for the Agro-industry sector in Europe) project aimed to develop Innovative Biomass Logistic Centres enhancing agricultural residues within existing production cycles. One of the study area of the project was Agios Kostantinos (Greece), a Greek locality in which the most important crop is olive tree. In this context pruning residues are actually seen mostly as a problem and not as a potential resource. According to what written above AGROinLOG activities in this study area aimed to develop a sustainable harvesting system for pruning residues, evaluating the performances of different machines currently available on market with a particular focus on machine performances and obtained biomass quality, in order to identify the best possible alternative for olive trees’ pruning harvesting and comminuting. One of the tested machine was the Greek Fotopoulos FSR2000. Conducted tests allowed to obtain an overall evaluation of this machine with particular references to work productivity, obtained biomass quality and economic performance of the harvesting systems. Notwithstanding Fotopoulos FSR2000 showed good performances for what concerning productivity and costs, obtained biomass quality resulted poor. Moreover the machine shows substantial design limits, for example the lack of a properly pick-up system. Thus Fotopoulos FSR2000 could represent an idea in order to minimize the initial investment but other machines, currently available on market, seemed to be more suitable for the aim of developing a IBLC in Agios Kostantinos context
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Integrated eutopic endometrium and non-depleted serum quantitative proteomic analysis identifies candidate serological markers of endometriosis
No full textBackground: Endometriosis affects about 4% of women in the reproductive age and is associated with subfertility. The aim of the present study was to examine the quantitative proteomic profile of eutopic endometrium and serum from women with endometriosis compared to controls in order to identify candidate disease-specific serological markers.Methods: Eutopic endometrium and serum from patients with endometriosis (n=8 for tissue and n=4 for serum) was respectively compared to endometrium and serum from females without endometriosis (n=8 for tissue and n=4 for serum) using a shotgun quantitative proteomics method. All study participants were at the proliferative phase of their menstrual cycle.Results: At the tissue and serum level, 1,214 and 404 proteins were differentially expressed (DEPs) in eutopic endometrium and serum respectively of women with endometriosis vs. control. Gene ontology analysis showed that terms related to immune response | inflammation, cell adhesion | migration and blood coagulation were significantly enriched in the DEPs of eutopic endometrium as well as serum. Twenty-one DEPs had the same trend of differential expression in both matrices and can be further examined as potential disease- and tissue-specific serological markers of endometriosis.Conclusions: The present in-depth proteomic profiling of eutopic endometrium and serum from women with endometriosis identified promising serological markers that can be further validated in larger cohorts for the minimally invasive diagnosis of endometriosis.<br/
Dissipative Range Scaling of Higher Order Structure Functions for Velocity and Passive Scalars
No full textDifferently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment moments and by direct numerical simulations
