In this paper we do a first approximation to identify which services offered by the Universidad Politécnica de Valencia could be improved with the use of new technologies
- PublicationEffect of gestational and lactational exposure to heat stress on performance in rabbits(Universitat Politècnica de València, 2017-03-30) Marco Jiménez, Francisco; García Diego, Fernando Juan; Vicente Antón, José Salvador; Dpto. de Física Aplicada; Dpto. de Ciencia Animal; Escuela Técnica Superior de Ingeniería Industrial; Instituto Universitario de Ciencia y Tecnología Animal; Escuela Técnica Superior de Ingeniería Agronómica y del Medio Natural; Centro de Investigación en Acuicultura y Medio Ambiente; Ministerio de Economía y Competitividad[EN] Reproductive performance is greatly affected by environmental factors such as temperature. Heat stress (HS) during pregnancy and lactation can influence not only foetal growth but also postnatal development of kits. The aim of this study was to test the effect of HS during gestation and lactation on postnatal growth till Spanish commercial liveweight. To investigate this, 32 primiparous non lactating rabbit does were exposed to 1 of 2 environmental treatments: high temperature (between 25 and 36°C, HS group; n=16) or thermoneutral conditions (between 14 and 20°C, TN group; n=16). Does were allowed to acclimate 30 d before the artificial insemination. At birth, kits were allocated into 4 groups: HS was only applied during gestation (G group; n=54); HS was applied during gestation and lactation period (GL group; n=85); HS was only applied during lactation period (L group; n=60); and TN was applied during gestation and lactation period (C group; n=77). All litters were kept under each experimental environment until weaning at day 30. Then, litters were moved to TN temperatures until slaughter at day 63. Compared with TN does, the HS does presented lower litter size (9.7 and 11.4; P<0.05), litter weight (503.0 vs. 630.5 g; P<0.05) and kit weight at birth (56.6 vs. 61.4 g; P<0.05), as well as a higher stillborn rate (25.4 vs. 9.9%; P<0.05). The kits from does subjected to HS during gestation (G group) had similar postnatal growth compared to offspring from does gestated in TN conditions (C group), whereas kits from does that experienced HS during gestation and lactation (GL group) and during their lactation (L group) presented decreased postnatal growth. Together, these results demonstrate that kits from does that underwent HS during gestation did not alter postnatal growth until Spanish commercial liveweight, whereas HS during lactation resulted in decreased postnatal growth.
- PublicationEnviromental responsability and corporate social responsability(Universitat Politècnica de València, 2015-12-29) Marí Farinós, Jesús; Centro de Investigación en Acuicultura y Medio Ambiente[EN] The environmental management of companies and organizations in general is going to be internalized in the operation and management structures, linking conceptual and chronologically to improve corporate reputation, management excellence, knowledge and innovation. Embracing, undoubtedly too, with the assumption of an ethical commitment of the company to society: environmental sustainability and generational solidarity in the transmission of culture and values of that nature. The existing need to know the potential impact of business operations on society and the environment results in the appearance of a document, which may well be called a Sustainability Report or Social Balance, which is compiled from a series social indicators, which are the instruments responsible to reflect the value of the shares held by the company in social and environmental fields.
- PublicationProduction costs differences between conventional, organic and integrated orange farming systems in the region of Valencia (Spain) through factor discriminant analysis(Universitat Politècnica de València, 2005) Peris Moll, Elena Mª; Juliá Igual, Juan Fco.; Balasch Parisi, Sebastià; Dpto. de Estadística e Investigación Operativa Aplicadas y Calidad; Escuela Técnica Superior de Ingeniería Agronómica y del Medio Natural; Centro de Investigación en Acuicultura y Medio Ambiente[EN] The aim of this paper was to compare orange production costs in the region of Valencia (Spain), which depend on the way they are grown (conventional, IP or organically), identifying at the same time the cost differences between them. With this purpose, and after analysing the three orange populations cultivated in the region, a sample was designed taking into account not only the location of the plots, but also the irrigation system available at the farm level (drip or flow irrigation). Once the field work was completed, a multivariate analysis, concretely a factor discriminant analysis was implemented to reach the objectives of the research. The results obtained were consistent with the degree of adoption of the different alternative citrus production systems in the region studied.
- PublicationSustainability as an object of corporate social responsibility(Universitat Politècnica de Valencia, 2017-06-13) Marí Farinós, Jesús; Centro de Investigación en Acuicultura y Medio Ambiente[EN] We can observe that in the last few years companies and organizations of any nature have begun to show an increasing interest in establishing sustainable relationships with the environment by bridging those groups that are impacted or that impact on their activities, . In this context, the social responsibility report emerges as a management tool that allows companies to be accountable to society and its groups and measure, their environmental, financial and social actions.The Triple Bottom Line, triple accountability or triple counting of results, should be understood as the methodology to measure and report the performance of organizations contrasted with environmental, economic and social parameters. In addition, it allows companies to surpass accountability solely for their economic value as it used to be in the past, and also to consider the social and environmental value they add or destroy.Concern about these social and environmental issues generates a demand for information, which, in turn, leads to the need to have a document that collects the information demanded by society and that should be offered by the Companies, what is known as Social Responsibility.It is the American companies that originally, already in the late sixties and early seventies, found themselves in need of having to offer information regarding their social responsibility. This information was collected in what, we might conclude, is the first social balances, which were addressed mainly to groups outside the company itself, especially to consumers, since in the United States it was this collective that showed a greater concern about the issue.
- PublicationTechnical Note: Design of a large variable temperature chamber for heat stress studies in rabbits(Editorial Universitat Politècnica de València, 2011) García Diego, Fernando Juan; Pascual Amorós, Juan José; Marco Jiménez, Francisco; Dpto. de Física Aplicada; Dpto. de Ciencia Animal; Escuela Técnica Superior de Ingeniería Industrial; Instituto Universitario de Ciencia y Tecnología Animal; Escuela Técnica Superior de Ingeniería Agronómica y del Medio Natural; Centro de Investigación en Acuicultura y Medio Ambiente; Ministerio de Ciencia e Innovación[EN] One of the major constraint factors for rabbit production consists of the environmental conditions and especially high temperatures that negatively affect reproduction and growth performance. For this reason, several studies have addressed the effects of heat stress and possible solutions to alleviate its impact on rabbit performance. This article describes the design and operating features of a large temperature chamber (13x4.7x3.1 m) configured to house 42 rabbits. The probes consisted of temperature sensor model DS2438 and humidity sensor model HIH-5031. The system was controlled by an Arduino platform programmed by its Integrated Development Environment (IDE) software. The system takes a decision every minute: it connects the heating if the temperature is lower than programmed and connects exhaust fans if the temperature is over the programmed setting. To renew the indoor air, every 5 min the system switches off the heating and switches on the exhaust fans for 15 sec. Two experiments (with and without animals) were carried out to test the temperature control accuracy. Firstly, without animals, two tests were performed: (i) adjusting the temperature of the climatic chamber to the control house temperature plus 10ºC and (ii) based on daily minimum (32ºC) and maximum (37ºC) temperatures. Secondly, with animals, does were maintained (i) between a daily minimum (32ºC) and maximum (37ºC) for 48 h and (ii) between a daily minimum (25ºC) and maximum (35ºC) temperatures for 105 d. Mortality rates were noted in both tests. The results of comparing the measured temperature deviation from programmed temperature reported a coefficient of determination of 0.9850 and 0.9947, for plus 10ºC and 32-37ºC curves, respectively. In the animal tests, the determination coefficients were 0.9926 and 0.9928 for programmed curve in the range of 32 to 37ºC and 0.9859, 0.9900 and 0.9901 for programmed curve in the range of 25 to 35ºC. Survival of females in the temperature chamber was as expected for reproductive rabbit does: 100 and 82% in the 2 and 105 d trials, respectively. Results indicate that the chamber provided precise temperature control for the development of heat stress studies in rabbits.
