Coffea sp. is cultivated in large areas, using both conventional and organic management. However, information about the sustainability of these two management systems is still deficient. The objective of the present study was to evaluate the physical properties of soil cultivated with Conilon coffee (C. canephora) under organic and conventional management. Two areas cultivated with Conilon coffee (under organic and conventional management) and a fragment of Atlantic forest, used as a reference, were selected for the experiment. Soil granulometry, hydraulic conductivity, water retention curve, resistance to penetration, porosity, optimal hydric interval, and other physical characteristics were measured at depths of 0 to 10 and 10 to 20 cm. The data was submitted to multivariate and descriptive statistical analyses. Higher similarity was observed between the soil cultivated with Conilon coffee under organic management and the Atlantic forest soil. Soil resistance to penetration at 10, 30, 100, 500 and 1500 kPa, macro porosity, density and total porosity were the main physical properties that differentiated both management systems studied. The non-use of agricultural machinery and the addition of organic matter may be the main reasons for higher soil sustainability observed under organic management when compared with the conventional system.

Changes in soils management systems, including the application of green manure, are able to increase crop productivity. The aim of this study was to propose a soil management system with the use of green manure to improve the nutritional status and melon productivity in the submedian of the São Francisco Valley. The experiment was installed in Typic Plinthustalf and conducted in split plot. There were two soil tillage systems, tillage (T) and no tillage (NT), and three types of green manure (two vegetal cocktails: VC1- 75% legumes (L) + 25% non-legumes (NL); VC2- 25% L+ 75% NL and spontaneous vegetation (SV)). The experimental design was a randomised block with four replications. Fourteen species of legumes, grasses and oilseeds were used for the composition of the plant cocktails. We evaluated production of the dry shoot and root biomass and carbon and nutrient accumulation by green manures and melon plant. Data were subjected to analysis of variance and the treatment means were compared by Tukey´s test (P<0.05). Shoot biomass production and carbon and nutrient accumulation were higher in plant mixtures compared to spontaneous vegetation. The root system of the plant cocktails added larger quantities of biomass and nutrients to the soil to a depth of 0.60 m when compared to the spontaneous vegetation. The cultivation of plant cocktails with soil tillage, regardless of their composition, is a viable alternative for adding biomass and nutrients to the soil in melon crops in semi-arid conditions, providing productivity increases.

This PhD work arises from the necessity to give a contribution to the energy saving field, regarding automotive applications. The aim was to produce a multidisciplinary work to show how much important is to consider different aspects of an electric car realization: from innovative materials to cutting-edge battery thermal management systems (BTMSs), also dealing with the life cycle assessment (LCA) of the battery packs (BPs). Regarding the materials, it has been chosen to focus on carbon fiber composites as their use allows realizing light products with great mechanical properties. Processes and methods to produce carbon fiber goods have been analysed with a special attention on the university solar car Emilia 4. The work proceeds dealing with the common BTMSs on the market (air-cooled, cooling plates, heat pipes) and then it deepens some of the most innovative systems such as the PCM-based BTMSs after a previous experimental campaign to characterize the PCMs. After that, a complex experimental campaign regarding the PCM-based BTMSs has been carried on, considering both uninsulated and insulated systems. About the first category the tested systems have been pure PCM-based and copper-foam-loaded-PCM-based BTMSs; the insulated tested systems have been pure PCM-based and copper-foam-loaded-PCM-based BTMSs and both of these systems equipped with a liquid cooling circuit. The choice of lighter building materials and the optimization of the BTMS are strategies which helps in reducing the energy consumption, considering both the energy required by the car to move and the BP state of health (SOH). Focusing on this last factor, a clear explanation regarding the importance of taking care about the SOH is given by the analysis of a BP production energy consumption. This is why a final dissertation about the life cycle assessment (LCA) of a BP unit has been presented in this thesis.

From its domestication until nowadays, the horse has assumed multiple roles in human society. Over time, this condition and the lack of specific regulation have led to the development of different kinds of management systems for this species. This Ph.D. research project aims to investigate horses' welfare in different management practices and housing systems, considering a multidisciplinary approach, taking into account biological function, naturalness, and affective dimension. The results are presented in five articles that evidence risk factors that can mine horse welfare, and examine tools and parameters that can be employed for its assessment. Our research shows the importance of considering the evolutionary history and the species-specific and behavioural needs of horses in their management and housing. Sociality, free movement, diet composition and foraging routine, and the workload that these animals undergo are important factors that should be taken into account. Furthermore, this research has evidenced the importance of employing different parameters (e.g., behaviour, endocrinological parameters, and immune activity) in welfare assessment and proposes the use of horsehair DHEA (dehydroepiandrosterone) as a possible useful additional non-invasive measure for the investigation of long-term stress conditions. Finally, our results underline the importance of considering the affective dimension in welfare research. Recently, Judgement Bias Tests (JBT), which are based on the influence of affective states on the decision-making process, have been widely employed in animal welfare research. However, our studies show that the use of spatial JBT in horses can have some limitations. Still today several management systems do not fulfill species-specific needs of horses, thus the implementation of specific regulations could ameliorate horse welfare. A multidisciplinary approach to welfare assessment is fundamental, but it should be always remembered the individual and its own characteristics, which can influence not only physiological, immunological, and behavioural responses but also emotional and cognitive dimensions.

This paper presents a collaborative virtual learning environment, which includes technologies such as 3D virtual representations, learning and content management systems, remote experiments, and collaborative learning spaces, among others. It intends to facilitate the construction, management and sharing of knowledge among teachers and students, in a global perspective. The environment proposes the use of 3D social representations for accessing learning materials in a dynamic and interactive form, which is regarded to be closer to the physical reality experienced by teachers and students in a learning context. A first implementation of the proposed extended immersive learning environment, in the area of solid mechanics, is also described, including the access to theoretical contents and a remote experiment to determine the elastic modulus of a given object.These instructions give you basic guidelines for preparing camera-ready papers for conference proceedings.

Since the second half of the 1990s, knowledge management has taken shape and has been firmly consolidated as a new discipline within the realm of organisations. The principal objective of this work is to determine whether content management systems (CMS) can become the most appropriate technological standard for consolidating this field. The article describes and analyses the major functions (publishing and exploitation) of these new systems. It then examines the field of knowledge management ¿what are the different types of knowledge that we can find within an organisational context¿ and then identifies and analyses the operations critical to managing it appropriately. The article concludes by evaluating the extent to which technological solutions provided by CMS can assist in properly implementing these critical operations.

Asiakaspalvelun tarjoamisesta Internet-verkon kautta tulee jatkuvasti tärkeämpää. Aitoa asiakashyötyä tuottavien palvelujen pystyttäminen ja tuottaminen on pienyritysten resursseilla vähintäänkin vaikeaa ja riskialtista. Mahdollisuus käyttää vapaaseen käyttöön lisensoituja avoimen lähdekoodin ohjelmistoja asiakkaille tarjottavien palvelujen perustana madaltaa näinollen pienyritysten kynnystä tarjota palvelua Internet-verkossa. Yrityksen tarjoamien palvelujen perustaksi on nykyään saatavilla jo kokonaisia valmiita avoimeen lähdekoodiin perustuvia ohjelmistosovelluksia. Suurin osa niistä on kuitenkin tehty jotakin rajattua tarkoitusta varten. Pyrittäessä laajentamaan asiakkaille tarjottua palvelua huomataankin tällöin, että ohjelmistosovelluksen laajentaminen muodostaa alkuperäistäkin korkeamman kynnyksen. Toisen ohjelmiston integrointi alkuperäisen kanssa ei sekään ole mahdollinen vaihtoehto – vaikka sellainen uuden palvelun perustaksi löytyisikin. WWW-sisällönhallintajärjestelmät sopivat yleiskäyttöisyytensä ansiosta hyvinkin vaihtelevien palveluiden perustaksi. Yrityksen verkkopalvelu voidaan toteuttaa esimerkiksi vapaasti saatavaan Plone-sisällönhallintajärjestelmään perustuen. Tällöin palvelujen laajentamisen ja uusien tarjoamisen kynnys oletettavasti madaltuu ratkaisevasti, järjestelmän valmiiksi sisältämien monipuolisten toimintojen ansiosta. Paikallisen pienyrityksen verkkopalvelua toteuttaessa todettiin Plonen olevan hyvin tarkoitukseen sopiva. Vähänkin merkittävämmät järjestelmään tehtävät muutokset edellyttävät kuitenkin varsin syvällistä perehtymistä sen osiin ja toimintaan. Koska tarjottavan palvelun tuli olla mahdollisimman helppo lähestyä ja käyttää, järjestelmää oli muun tarvittavan räätälöinnin lisäksi vielä muutettava yksinkertaisemmaksi: Esimerkiksi järjestelmän tarjoamasta valmiista käyttöliittymästä oli räätälöitävä yksinkertaistettu palvelunkäyttöliittymä. Myös palvelun ylläpitäjien koulutukseen oli panostettava. Järjestelmän ylläpidosta tehtiin palvelusopimus, koska asiakkaalla ei ole tarvittavaa teknistä osaamista.
