Innovative Service-Based Business Concepts for the Machine Tool Building Industry

Organised by: Cranfield UniversityDuring the last decade, machine tool building companies have been forced to put innovative offers on the market. Due to the technical features of their products and the prevailing organizational structures in this sector, especially product-service systems are a promising way of creating a unique selling point. In this paper, potential new business concepts for machine tool builders will be presented which aim at fulfilling basic customer needs like the increase in quality, flexibility, productivity and the reduction of lead times, costs and risks. For the implementation of these product-service systems, practical examples are given.Mori Seiki – The Machine Tool Compan

The Effects of Microbial Inoculation on Short-to-Long Fermentation and Aerobic Stability of Grass-Legume Silage Ensiled in Big Bales

Wilted (35.9 % DM and 2.6% WSC) moderately difficult to ensile grass-legume mixture (red clover, alfalfa and timothy 50:20:30) was ensiled in cylindrical big bales (1.2 m hight and 1.2 m diameter) with a weight about 700 kg. The crop was ensiled for 8, 32 and 120 days with or without a microbial inoculation (SiloSolve® FC containing Lactococcus lactis DSM 11037/1k2081 and Lactobacillus buchneri DSM 22501/1k20738 applied at 1.5×105 CFU g-1 forage). Ten bales per treatment were prepared for each fermentation period. After each period of ensiling the big bales were opened, sampled, and tested for fermentation parameters, yeast and mould counts and aerobic stability. Weight loss during fermentation and aerobic exposure were recorded and DM losses were calculated. After 8 days of fermentation, the addition of SiloSolve® FC showed only significant positive effects on pH, acetic and butyric acid, while after 32 and 120 days of fermentation periods, significant improvements of adding SiloSolve® FC were observed across all parameters investigated. The results show that SiloSolve® FC is an effective treatment to reduce ammonia, ethanol, and butyric acid production, to control yeast and mould growth, and to improve acetic acid levels with a resulting improved aerobic stability of grass-legume mixture fermented in big bales. Total lactic acid bacteria increased significantly and an appreciable decrease number of yeasts were detected in the inoculated silage at all fermentation time points and after aerobic exposure if compared with untreated silage. Reduction in yeast and mould population during anaerobic phase of silage fermentation and during silage aerobic exposure period appears to be the main reason for the improvement aerobic stability of the inoculated silage. Improved fermentation, reduced DM loss during fermentation and during aerobic exposure periods lead to increase nutritive value of the inoculated silage

An enhanced expression of the immediate early gene, Egr-1, is associated with neuronal apoptosis in culture

Cultured cerebellar granule cells grown in medium containing 10 mM K+ (K10) underwent apoptosis after four to five days in vitro, unless they were rescued by the addition of insulin-like growth factor-I. The few GABAergic neurons present in the cultures were more resistant to apoptotic degeneration, as indicated by double fluorescent staining with the chromatin dye Hoechst 33258 and with glutamate decarboxylase-67 antibodies. As compared with sister cultures grown in 25 mM K+, K10 cultures showed an increased expression of the Egr-1 protein and a reduced expression of the Fos protein, The increase in Egr-1 was more substantial in granule cells than in GABAergic neurons, and was not oberved in K10 cultures chronically exposed to insulin-like growth factor-I. To examine the temporal relationship between the increase in Egr-1 and the development of programmed cell death, we induced apoptosis in K25 cultures at six days in vitro by replacing their medium with serum-free K10 medium. A substantial, but transient, increase in Egr-1 expression was observed in granule cells 6 h after switching the medium, a time that preceded the appearance of the phoenotypical markers of apoptotic death. An early reduction in the Fos protein was observed after switching the medium from K25 into serum-free K10, but also after switching the medium into serum-free K25, a condition which was not associated with the development of apoptosis nor with the increase in Egr-1. We suggest that a transient induction of Egr-1 contributes to the chain of events leading to the execution phase of neuronal apoptosis in culture. (C) 1999 IBRO. Published by Elsevier Science Ltd

Leguminosas bioactivas para mejorar el perfil lipídico de la carne de cordero

6 páginas, 2 figuras, 1 tabla.La utilización de leguminosas forrajeras en la dieta de los rumiantes puede ofrecer importantes ventajas. Además de su elevado valor proteico, algunas especies como la esparceta o el trébol rojo, contienen compuestos bioactivos que podrían mejorar la calidad nutricional de la carne. Entre ellos, destacan los taninos en la esparceta y la polifenol oxidasa en el trébol rojo. Ahora bien, la climatología de muchas áreas limita su aprovechamiento en verde. En este estudio, mostramos que la utilización de la esparceta y el trébol rojo conservados mediante ensilado podría ser una buena alternativa para la alimentación de corderos, al aumentar la concentración de ácidos grasos poliinsaturados (PUFA) en la carne a través de su efecto sobre el metabolismo lipídico ruminal. Aunque el mecanismo de acción de los compuestos bioactivos presentes en estos forrajes probablemente sea distinto, sus efectos sobre el perfil de ácidos grasos de la carne parecen ser similares y aditivos.Este trabajo forma parte del proyecto Legume Plus, financiado por la Comisión Europea a través de una Red de Formación Inicial Marie Curie (PITN GA- 2011- 289377) PG .

Agronomic, Energetic and Environmental Aspects of Biomass Energy Crops Suitable for Italian Environments

The review, after a short introduction on the tendencies of the European Community Policy on biomasses, describes the agronomic, energy potential and environmental aspects of biomass crops for energy in relation to the research activity carried out in Italy on this topic, differentiating crops on the basis of the main energy use: biodiesel and bioethanol (which refers to "first generation biofuel"), heat and electricity. Currently, many of the crops for potential energy purposes are food crops (wheat, barley, corn, rapeseed, soybean, sunflower, grain sorghum, sugar beet) and their production may be used as biofuel source (bioethanol and biodiesel) since their crop management aspects are well known and consequently they are immediately applicable. Other species that could be used, highly productive in biomass, such as herbaceous perennial crops (Arundo donax, Miscanthus spp., cardoon), annual crops (sweet sorghum), short rotation woody crops (SRF) have been carefully considered in Italy, but they still exhibit critical aspects related to propagation technique, low-input response, harvest and storage technique, cultivars and mechanization. Crops for food, however, often have negative energetic indices and environmental impacts (carbon sequestration, Life Cycle Assessment), consequent to their low productivity. Conversely, crops which are more productive in biomass, show both a more favourable energy balance and environmental impact

On farm agronomic and first environmental evaluation of oil crops for sustainable bioenergy chains.

Energy crops, and in particular oil crops, could be an important occasion for developing new non food production rows for a new multi-functional agriculture in Italy. In this view, the use of local biomass is a fundamental starting point for the development of a virtuous energy chain that should pursue not only agricultural profitability, but also chain sustainability and that is less dependent on the global market, characterized by instability in terms of biomass availability and price. From this perspective, particular attention must be paid to crop choice on the basis of its rusticity and of its adaptability to local growing conditions and to low input cropping systems. In this context, alike woody and herbaceous biomasses, oil crops such as sunflower and rapeseed should be able to support local agricultural bioenergy chain in Italy. In addition, in a local bioenergy chain, the role of the farmers should not be limited just to grain production; but also grain processing should be performed at farm or consortium level in oilseed extraction plants well proportioned to the cropped surface. In this way, by means of a simple power generator, farmer could thus produce its own thermal and electric energy from the oil, maximizing his profit. This objective could also be achieved through the exploitation of the total biomass, including crop residues and defatted seed meals, that may be considered as fundamental additional economic and/or environmental benefits of the chain. This paper reports some results of three-years on-farm experiments on oil crop chain carried out in the framework of "Bioenergie" project, that was focused to enhance farmers awareness of these criteria and to the feasibility at open field scale of low-input cultivation of rapeseed, sunflower and Brassica carinata in seven Italian regions. In several on-farm experiences, these crops produced more than 800 kg ha-1 of oil with good energy properties. Defatted seed meals could be interesting as organic fertilizers and, in the case of B. carinata, as a biofumigant amendment that could offer a total or partial alternative to some chemicals in agriculture. Furthermore, biomass soil incorporation could contribute to C sequestration, catching CO2 from atmosphere and sinking a part in soil as stable humus. Finally, four different open field experiences carried out again in the second year of the project, have been analysed in order to evaluate their energy and greenhouse gasses balance after cultivation phase

Intracranial V. cholerae Sialidase Protects against Excitotoxic Neurodegeneration

Converging evidence shows that GD3 ganglioside is a critical effector in a number of apoptotic pathways, and GM1 ganglioside has neuroprotective and noötropic properties. Targeted deletion of GD3 synthase (GD3S) eliminates GD3 and increases GM1 levels. Primary neurons from GD3S−/− mice are resistant to neurotoxicity induced by amyloid-β or hyperhomocysteinemia, and when GD3S is eliminated in the APP/PSEN1 double-transgenic model of Alzheimer's disease the plaque-associated oxidative stress and inflammatory response are absent. To date, no small-molecule inhibitor of GD3S exists. In the present study we used sialidase from Vibrio cholerae (VCS) to produce a brain ganglioside profile that approximates that of GD3S deletion. VCS hydrolyzes GD1a and complex b-series gangliosides to GM1, and the apoptogenic GD3 is degraded. VCS was infused by osmotic minipump into the dorsal third ventricle in mice over a 4-week period. Sensorimotor behaviors, anxiety, and cognition were unaffected in VCS-treated mice. To determine whether VCS was neuroprotective in vivo, we injected kainic acid on the 25th day of infusion to induce status epilepticus. Kainic acid induced a robust lesion of the CA3 hippocampal subfield in aCSF-treated controls. In contrast, all hippocampal regions in VCS-treated mice were largely intact. VCS did not protect against seizures. These results demonstrate that strategic degradation of complex gangliosides and GD3 can be used to achieve neuroprotection without adversely affecting behavior

Selective mGluR1 Antagonist EMQMCM Inhibits the Kainate-Induced Excitotoxicity in Primary Neuronal Cultures and in the Rat Hippocampus

Abundant evidence suggests that indirect inhibitory modulation of glutamatergic transmission, via metabotropic glutamatergic receptors (mGluR), may induce neuroprotection. The present study was designed to determine whether the selective antagonist of mGluR1 (3-ethyl-2-methyl-quinolin-6-yl)-(4-methoxy-cyclohexyl)-methanone methanesulfonate (EMQMCM), showed neuroprotection against the kainate (KA)-induced excitotoxicity in vitro and in vivo. In in vitro studies on mouse primary cortical and hippocampal neuronal cultures, incubation with KA (150 μM) induced strong degeneration [measured as lactate dehydrogenase (LDH) efflux] and apoptosis (measured as caspase-3 activity). EMQMCM (0.1–100 μM) added 30 min to 6 h after KA, significantly attenuated the KA-induced LDH release and prevented the increase in caspase-3 activity in the cultures. Those effects were dose- and time-dependent. In in vivo studies KA (2.5 nmol/1 μl) was unilaterally injected into the rat dorsal CA1 hippocampal region. Degeneration was calculated by counting surviving neurons in the CA pyramidal layer using stereological methods. It was found that EMQMCM (5–10 nmol/1 μl) injected into the dorsal hippocampus 30 min, 1 h, or 3 h (the higher dose only) after KA significantly prevented the KA-induced neuronal degeneration. In vivo microdialysis studies in rat hippocampus showed that EMQMCM (100 μM) significantly increased γ-aminobutyric acid (GABA) and decreased glutamate release. When perfused simultaneously with KA, EMQMCM substantially increased GABA release and prevented the KA-induced glutamate release. The obtained results indicate that the mGluR1 antagonist, EMQMCM, may exert neuroprotection against excitotoxicity after delayed treatment (30 min to 6 h). The role of enhanced GABAergic transmission in the neuroprotection is postulated
