Experimental Evaluation of the Tribotechnical Properties of Engine Oils for Combine Harvesters
No full textA four-ball extreme pressure test has been performed to study and evaluate the tribotechnical properties of motor oils. The studies have shown that the tribotechnical properties of the engine oil stored in the
crankcase during the winter period exhibit a significant change. The average ball wear level has shown a 40% increase compared with that observed in the case of new oil. The average ball wear diameter for the oil samples taken from the combine engines in autumn amounted to 0.5 mm, whereas the average ball wear diameter for the oil samples taken from combine engines in spring amounted to 0.7 mm. When testing new semisynthetic engine oil, the average ball wear diameter varied within 0.48 ± 0.04 mm. It is assumed that the boundary layer formed by the oil is weaker, which causes an increase in the risk of its breaking and sealing the friction pores
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Towards the European harmonisation of a Soil Cadastre inventory as a tool for environmental, social, economic, legal and taxation purposes
No full textThe cadastral systems existing in EU Member States satisfy private and public needs but there is no common regulation describing the purposes, minimum requirements and functions of the Cadastre in each State.
In order to satisfy the need for harmonisation of Cadastres at the EU level, the Spanish Government’s Official Performance Programme of the Spanish Presidency of the EU Council supported, in the first semester of 2002, the initiative proposed by the Spanish General Directorate for the Cadastre to hold the “First Congress on Cadastre in the European Union” (15-17 May 2002). The main objective of this conference was to study the role of the Cadastre at EU level and the methods for the integration of national models.
For this purpose the Spanish General Directorate also presented two specific initiatives:
1) the project for a “Declaration on Cadastre in the European Union”;
2) the formation of a Cadastre Permanent Committee.
A unique Cadastre at EU level would allow that the CAP (Community Agricultural Policy) is implemented by considering the best practices of the land owners. Moreover, the basic taxation principles and coordination of property taxation are shown in this paper. In the long term, the free movement of people, goods and capital will
induce that the EU harmonises or at least coordinates property regimes, Land Registry and Cadastre in the Member States.
Cadastres enable to change the land from an object of utilisation into capital and thus economic growth (that is a prerequisite for investments in estate enhancement and/or environmental protection). This is an essential part of LIS (Land Information System) and GIS (Geographic Information System) systems, that provide information
crucial to decision making.
The new soil cadastral certificate, besides land use and capability, should also take into account the sustainability.
The Ground Cadastre should be developed into a multipurpose Soil Cadastre, i.e. an inventory for environmental, social, economic, legal and taxation purposes
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Life Cycle Impact Assessment applied to cactus pear crop production for generating bioenergy and biofertiliser
No full textAmong the potential uses of cactus pear, the generation of bioenergy (biogas) and
biofertiliser (digestate), from the Anaerobic Digestion (AD) of cladodes and fruits,
is surveyed in this paper.
Data for Life Cycle Impact Assessment (LCIA) was drawn from a farm located in
Roccapalumba (Palermo, Sicily, Italy), where three cultivars were cultivated: 1) yellow
pulp cultivar; 2) red pulp cultivar; 3) white pulp cultivar. LCIA was applied to
six scenarios: 1) current dry crop; 2) current irrigated crop; 3) dry crop for fruit and
bioenergy production; 4) irrigated crop for fruit and bioenergy production; 5) dry
crop for bioenergy production; 6) irrigated crop for bioenergy production.
According to LCIA, the highest total GHG emissions were found in Scenarios 2 and
4, while the lowest ones were found in Scenario 5. Moreover, the highest share of
environmental impact for Scenarios 2, 4 and 6 is associated with the consumption of
cardboard boxes used for collecting and transporting fruits, crop irrigation and a
higher human work load.
Furthermore, the digestate obtained from the AD process contains nutrients which
make it a valuable biofertiliser, so that it reduces the expenditure for mineral fertilisers
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
Nomenclature for Hydrogeological Instability Risks
Full text linkThe nomenclature for hydrogeological instability risks includes four main risks, which are distinguished according to the risk causes :
1) hydrogeological risk, that is slowly caused by natural factors (e.g. collapse landslides in a calcareous cliff in uninhabited areas and erosion along a marly-calcareous slope) in environments where human activities are minimal, i.e. woods, forests and mountain pastures;
2) hydraulic-pedological farming risk, that implies the occurrence of landslides in every winter and is caused by incorrect crop selection, not suitable for the soil and climate parameters (e.g. on a hilly slope with a clay vertisol type with a landslide having different fronts, when the arable land is cultivated with a cereal-legume crop rotation), or the presence of springs with missing drainage in clay soils with a high gradient;
3) hydraulic-infrastructural risk, that is caused by the building up of infrastructures not suitable for the surrounding environment, as they change the downflow of shallow water;
4) hydraulic-infrastructural-pedological-management risk, that is caused by crop operations not suitable for soil and crop parameters, where the selected cultivated plant species are suitable for the environment and field improvements change water downflow (e.g. in soils along hilly calcarenite slopes cultivated with olive orchards, where up-down soil tillage causes shallow water erosion)
The evaluation of urban soils aimed at the sustainability of plants in public and private flowerbeds
No full textThe authors report the survey of some flowerbeds located in the city of Palermo with
the aim of assessing the sustainability of the plants and the interventions to be implemented, i.e. cutting or transfer of plants, to achieve a sustainable green. In the case in which it is possible to insert other plants in the flowerbeds, it is recommended to elaborate a project using programs that allow to have a preview of the spaces
available for the new plants. This work is methodological and is aimed at creating a green that can achieve the functional objectives in relation to the site where it is located (sustainability in all aspects) and at low management costs with no or almost no irrigation practice
