Hamburg is a growing metropolitan city. The increase in sealed surfaces of about 0.36% per year and the subsequent increased runoff impacts on the city's wastewater infrastructure. Further potential risks to the drainage infrastructure arise also from effects of climate change, e.g. increased intensity and frequency of heavy rainfalls. These challenges were addressed in the Rain InfraStructure Adaption (RISA) project conducted 2009-2015 by HAMBURG WASSER and the State Ministry for Environment and Energy, supported by several municipal stakeholders. RISA addressed intensifying conflicts in the context of urban development and stormwater management at that time. Major results of the project are improvements and recommendations for adequate consideration of stormwater management issues during urban planning as well as new funding mechanisms for stormwater management measures. The latter topic resulted in the introduction of a separated stormwater charge based on the amount of sealed area connected to the sewer system of each property. For both undertakings - the RISA project and the introduction of the separated stormwater charge - a novel, comprehensive, digital database was built. Today, these geographical information system (GIS)-based data offer various scale-independent analysis and information opportunities, which facilitate the day-to-day business of HAMBURG WASSER and stormwater management practice in Hamburg.

Such an effect is of great interest for the fabrication of opto-electronic devices such as light emitting diodes with nanometer size emitting points and solar cells comprising of blends of electron donating and electron accepting polymers. populärwissenschaftlicher Abstract: Kristallisation, Biomimetik und halbleitende Polymere in räumlich begrenzten Systemen: Äl und Wasser mischen sich nicht, man kann aber aus beiden Flüssigkeiten Emulsionen herstellen, bei denen Tröpfchen der einen Flüssigkeit in der anderen Flüssigkeit vorliegen. Das heit, es können entweder Ältröpfchen in Wasser oder Wassertröpfchen in Äl erzeugt werden. Aus täglichen Erfahrungen, z.B. beim Kochen wei man jedoch, dass sich eine Emulsion durch Schütteln oder Rühren herstellen lässt, diese jedoch nicht besonders stabil ist. Mit Hilfe von hohen Scherenergien kann man nun sehr kleine, in ihrer Gröe sehr einheitliche und auerdem sehr stabile Tröpfchen von 1/10000 mm erhalten. Eine solche Emulsion wird Miniemulsion genannt. In der Dissertation wurden nun z.B. Miniemulsionen untersucht, die aus kleinen Wassertröpfchen in einem Äl bestehen. Es konnte gezeigt werden, dass das Wasser in diesen Tröpfchen, also in den räumlich begrenzten Systemen, nicht bei 0 °C, sondern bei -22 °C kristallisierte. Wie lässt sich das erklären? Wenn man einen Eimer Wasser hat, dann bildet sich normalerweise bei 0 °C Eis, da nämlich in dem Wasser einige (manchmal ganz wenige) Keime (z.B. Schutzteilchen, ein Fussel etc.) vorhanden sind, an denen sich die ersten Kristalle bilden. Wenn sich dann einmal ein Kristall gebildet hat, kann das Wasser im gesamten Eimer schnell zu Eis werden. Ultrareines Wasser würde bei -22 °C kristallisieren. Wenn man jetzt die Menge Wasser aus dem Eimer in kleine Tröpfchen bringt, dann hat man eine sehr, sehr groe Zahl, nämlich 1017 Tröpfchen, in einem Liter Emulsion vorliegen

Die Nachweise einer schadlosen Ableitung von Abwässern lassen sich bis weit in die Vergangenheit zurückverfolgen. Sie waren bereits zur damaligen Zeit eine Forderung zur Pflege der öffentlichen Reinlichkeit. Der Kanalisationsbau ist auch immer ein Ausdruck der Kultur eines Volkes gewesen. So kann festgestellt werden, dass im Zusammenhang mit der Hochkultur eines Volkes auch der Kanalbau ein vorherrschendes Thema war. Der Kanalbau steht auch in einem engen Zusammenhang mit dem Wasserleitungsbau. Es ist nur logisch, dass dort wo Wasser teilweise aus großer Entfernung herangeführt worden ist, dieses dann nach Gebrauch auch wieder schadlos beseitigt werden musste.

Imaging observations of lower thermospheric O(1S) and O2 airglow emissions from STS 9 - Implications of height variations

1989-01-01

The lower thermospheric nightglow in the Southern Hemisphere was observed with the Atmospheric Emissions Photometric Imager during the Spacelab 1 mission in December, 1983. Observations of emission from O(1S) at 2972 and 5577A, O2 at 7620 A, OH near 6300 A, and the combined emission from the three upper states of O2 which lead to the Herzberg I and II and Chamberlain band emissions in B and near UV are discussed. The altitudes of peak emission heights are determined, showing that the peak heights are not constant with latitude. It is found that airglow heights varied with latitude by as much as 8 km. The observed airglow height pattern near the equator is similar to that of Wasser and Donahue (1979).

Numerische Szenariosimulationen zur Ausbreitung von hochmineralisiertem Wasser in oberflächennahen Süßwasseraquiferen

In areas where the geological subsurface is used for storage of gases or fracking, there is a risk of saline formation water entering protected aquifers. The impact of such potential leakage therefore needs to be evaluated at relevant sites to develop practical monitoring concepts. Three-dimensional numerical simulations and a sensitivity analysis are performed to determine the influence of aquifer parameters, ground water flow, aquifer morphology, leakage rate and NaCl-concentration of the intruding water on the propagation behaviour of saline water. Two example scenarios were simulated based on a realistic site-scale conceptual model, one with water from the lower Braunkohlensande, (NaCl = 7.61 g/l) the other with saline water from the Bunter sandstone formation (NaCl = 280.3 g/l). The simulations show that saltwater migrates along the bottom of the aquifer, and that groundwater flow can dominate the transport of chloride. In this case the spreading of denser water is not influenced by the aquifer's morphology.

Agaricus bisporus (J. E. Lange) Emil J. Imbach and Agaricus brasiliensis Wasser, M. Didukh, Amazonas & Stamets are edible mushrooms. We chemically characterized these mushrooms for nutritional value, hydrophilic and lipophilic compounds. The antioxidant and antimicrobial activities of methanolic and ethanolic extracts were assessed. Hepatotoxicity was also evaluated. The ethanolic extract of both species was tested for inhibition of Listeria monocytogenes growth in yoghurt. Both species proved to be a good source of bioactive compounds. A. brasiliensis was richer in polyunsaturated fatty acids and revealed the highest concentration of phenolic acids, and tocopherols. A. bisporus showed the highest monounsaturated fatty acids and ergosterol contents. A. brasiliensis revealed the highest antioxidant potential, and its ethanolic extract displayed the highest antibacterial potential; the methanolic extract of A. bisporus revealed the highest antifungal activity. A. brasiliensis possessed better preserving properties in yoghurt.

Energie aus der Tiefe: Geothermische Stromerzeugung

2004-11-01

Die Erde birgt überall genug Wärme für die geothermische Erzeugung elektrischen Stroms, die allerdings Wassertemperaturen von über 150 °C braucht. So warme Gesteinsschichten liegen in Mitteleuropa in mindestens 4 km Tiefe. Ein Kraftwerk muss also beim Betrieb über tiefe Bohrungen Wasser durch das Tiefengestein zirkulieren und dort erhitzen. Von Natur aus ist das Gestein jedoch dafür meist zu wenig porös. Deshalb soll das Einpressen von Fluiden unter hohem Druck die natürlichen Risse im Reservoirgestein künstlich vergrößern. Diese Stimulationstechnik erprobte das GeoForschungsZentrum Potsdam erfolgreich an einer 4309 m tiefen Bohrung im Geothermielabor Groß Schönebeck. Eine zweite Bohrung soll nun eine langfristige Wasserzirkulation im Untergrund erforschen. Funktioniert sie stabil, dann soll eine Demonstrationsanlage Strom erzeugen.

2012-04-01

Understanding the dynamics of fluvial ecosystems linked to hydrology is one of the most important challenges of ecohydrology. In fact, streamflow, which chiefly relies on rainfall, climate, land use and geomorphologic properties, plays a fundamental role in sustaining and regulating fluvial ecosystem integrity. To analyze possible implications of hydrological fluctuations on the biofilm-grazer interaction, an experimental campaign has been conducted between June and September 2011 at the Wasser Cluster Lunz, in Lunz am See (AU). 36 flumes have been used to perform biofilm growth and grazing activity under two distinct discharge conditions (i.e., constant and stochastic discharge regimes) and four different light regimes (from natural light conditions to nearly 70% attenuation). Experimental results concerning (i) dynamics of biofilm growth, (ii) grazing effect, and (iii) grazing rate will be presented. Results of performed statistical analysis for testing the effects of discharge treatment and light regime on the grazing rate will be also discussed.

High resolution modelling of wind fields for optimization of empirical storm flood predictions

NASA Astrophysics Data System (ADS)

Brecht, B.; Frank, H.

2014-05-01

High resolution wind fields are necessary to predict the occurrence of storm flood events and their magnitude. Deutscher Wetterdienst (DWD) created a catalogue of detailed wind fields of 39 historical storms at the German North Sea coast from the years 1962 to 2011. The catalogue is used by the Niedersächsisches Landesamt für Wasser-, Küsten- und Naturschutz (NLWKN) coastal research center to improve their flood alert service. The computation of wind fields and other meteorological parameters is based on the model chain of the DWD going from the global model GME via the limited-area model COSMO with 7 km mesh size down to a COSMO model with 2.2 km. To obtain an improved analysis COSMO runs are nudged against observations for the historical storms. The global model GME is initialised from the ERA reanalysis data of the European Centre for Medium-Range Weather Forecasts (ECMWF). As expected, we got better congruency with observations of the model for the nudging runs than the normal forecast runs for most storms. We also found during the verification process that different land use data sets could influence the results considerably.

Comparison of hydromorphological assessment methods: Application to the Boise River, USA

Benjankar, Rohan; Koenig, Frauke; Tonina, Daniele

2013-06-01

Recent national and international legislation (e.g., the European Water Framework Directive) identified the need to quantify the ecological condition of river systems as a critical component for an integrated river management approach. An important defining driver of ecological condition is stream hydromorphology. Several methodologies have been proposed from simple table-based approaches to complex hydraulics-based models. In this paper, three different methods for river hydromorphological assessment are applied to the Boise River, United States of America (USA): (1) the German LAWA overview method (Bund/Laender Arbeitsgemeinschaft Wasser/German Working Group on water issues of the Federal States and the Federal Government represented by the Federal Environment Ministry), (2) a special approach for a hydromorphological assessment of urban rivers and (3) a hydraulic-based method. The hydraulic-based method assessed stream conditions from a statistical analysis of flow properties predicted with hydrodynamic modeling. The investigation focuses on comparing the three methods and defining the transferability of the methods among different contexts, Europe and West United States. It also provides comparison of the hydromorphological conditions of an urban and a rural reaches of the Boise River.

The Royal Sun mushroom, the Himematsutake culinary-medicinal mushroom, Agaricus brasiliensis has several polyphenoloxidase activities in a broad sense. Here we report the partial purification of tyrosinase-type polyphenoloxidase (PPO). PPO is purified from A. brasiliensis without browning using a two-phase partitioning with Triton X-114 and ammonium sulfate fractionation. Partially denaturing SDS-PAGE (sodium dodecyl sulfate-polyacrylamide electrophoresis) staining with L-3,4-dihydroxyphenylalanine was performed and the indicated molecular sizes were approximately 70 kDa and 45 kDa. The purified enzyme is in its latent state and can be activated maximally in the presence of 1.6 mM sodium dodecyl sulfate (SDS). This enzyme catalyzes two distinct reactions, monophenolase and diphenolase activity, and the monophenolase activity showed a lag time typical of polyphenoloxidase. The K(m) value for 4-tert-butylcatechol was quite similar in the presence and absence of SDS, but the apparent V(max) value was increased 2.0-fold by SDS. Mimosine was a typical competitive inhibitor with K(i) values of 138.2 microM and 281.0 microM n the presence and absence of SDS, respectively.

The effect of culinary-medicinal Royal Sun Agaricus (Agaricus brasiliensis) hot water extract on methyl methane sulfonate (MMS) induced mutagenicity/genotoxity in Drosophila melanogaster was studied using a quick and broadly applicable in vivo assay, i.e., the wing somatic mutation and recombination test. We used 2nd instar larvae, trans-heterozygous for the third chromosome recessive markers, i.e., multiple wing hairs (mvh) and flare-3 [flr (3)], and fed them for 24 h with the aqueous extract of A. brasiliensis. For antigenotoxicity studies a 24-h pretreatment with the extract was done, followed by a 48-h treatment of the then 3rd instar larvae with MMS. The frequency of mutations of the wing blade changes (i.e., of the number of wing spots of different sizes) induced in somatic cells was determined as a parameter of genetic changes of the wing imaginal discs. The results showed that A. brasiliensis extract did not cause any genotoxic or mutagenic effects. No antigenotoxic and/or protective effect against the induction of mutations by MMS was observed. Instead, a possible enhanced mitotic recombination frequency by MMS was seen after pretreatment of the larvae with A. brasiliensis extract. Possible mechanisms of action are discussed.

Can soda fountains be recommended in hospitals?

PubMed

Chaberny, Iris F; Kaiser, Peter; Sonntag, Hans-Günther

2006-09-01

Mineral water (soda water) is very popular in Germany. Therefore, soda fountains were developed as alternatives to the traditional deposit bottle system. Nowadays, different systems of these devices are commercially available. For several years, soda fountains produced by different companies have been examined at the University Hospital of Heidelberg. In 1998, it was possible for the first time to observe and evaluate one of these systems over a period of 320 days in a series of microbiological examinations. The evaluation was implemented on the basis of the German drinking water regulation (Anonymous, 1990. Gesetz über Trinkwasser und Wasser für Lebensmittelbetriebe (Trinkwasserverordnung - TrinkwV) vom 12. Dezember 1990. Bundesgesetzblatt 66, 2613ff). Initially, the bacteria counts exceeded the reference values imposed by the German drinking water regulation in almost 50% of the analyses. Pseudomonas aeruginosa was also detected in almost 38% of the samples. After a re-arrangement of the disinfection procedure and the removal of the charcoal filter, Pseudomonas aeruginosa was not detectable any more. However, the bacteria counts still frequently exceeded the reference values of the German drinking water regulation. Following our long-term analysis, we would not recommend soda fountains in high-risk areas of hospitals. If these devices are to be used in hospitals, the disinfection procedures should be executed in weekly or fortnightly intervals and the water quality should be examined periodically.

Methods: Twenty-seven adults with sleep disturbance meeting DSM-IV diagnostic criteria for GAD and partially responsive on an SSRI or SNRI by randomization visit (as signified by a Hamilton Anxiety scale [HAMA] maximum score of 15 and minimum of 8, Clinical Global Impressions Severity of Illness [CGI-S] scale of ≤ 4 and ≥ 2 [measuring anxiety symptoms], CGI-S of ≥ 4 [measuring insomnia symptoms], ≥ 5 on the Pittsburgh Sleep Quality Index [PSQI], and ≥ 10 on the Epworth Sleepiness Scale [ESS]) were treated openly for 10 weeks on ramelteon 8 mg at bedtime. Analysis was conducted using repeated measures methodology. Patient reported sleep diaries were maintained throughout the study. Results: Significant symptom reduction was observed on all scales (HAMA, ESS, CGI-I, CGI-S), with subjects falling asleep faster and sleeping longer. Headache upon stopping ramelteon, daytime tiredness, agitation, and depression were the most commonly reported side effects and were cited as transient. Conclusion: Data from this 12-week open-label study suggests ramelteon is an effective and generally well tolerated treatment for insomnia symptoms in this community sample of adults with GAD.

BACKGROUND: The present article outlines the process of instituting an assessment of risk of problematic use of medications with new patients in an ambulatory chronic noncancer pain (CNCP) clinic. It is hoped that the authors’ experience through this iterative process will fill the gap in the literature by setting an example of an application of the ‘universal precautions’ approach to chronic pain management. OBJECTIVES: To assess the feasibility and utility of the addition of a new risk assessment process and to provide a snapshot of the risk of problematic use of medications in new patients presenting to a tertiary ambulatory clinic treating CNCP. METHODS: Charts for the first three months following the institution of an intake assessment for risk of problematic medication use were reviewed. Health care providers at the Wasser Pain Management Centre (Toronto, Ontario) were interviewed to discuss the preliminary findings and provide feedback about barriers to completing the intake assessments, as well as to identify the items that were clinically relevant and useful to their practice. RESULTS: Data were analyzed and examined for completeness. While some measures were considered to be particularly helpful, other items were regarded as repetitive, problematic or time consuming. Feedback was then incorporated into revisions of the risk assessment tool. DISCUSSION: Overall, it is feasible and useful to assess risk for problematic use of medications in new patients presenting to CNCP clinics. CONCLUSION: To facilitate the practice of assessment, the risk assessment tool at intake must be concise, clinically relevant and feasible given practitioner time constraints. PMID:22891193

If these are eliminated, which is relatively simple over a water surface, the differences between calculated and measured...divergences at these levels is less than 20%, on the average. The relative variation of the divergence with height is somewhat greater over water than over land, due to the different temperature profiles. (Author)

Culinary-medicinal Royal Sun mushroom, Agaricus brasiliensis (AbS), has traditionally been used for the prevention of a range of diseases, including cancer, hepatitis, atherosclerosis, hypercholesterolemia, diabetes, and dermatitis. The hepatoprotective effect of the fermented mushroom of A. brasiliensis (FMAE) and wild-growing A. brasiliensis (WMAE) were studied in this paper. An in vivo study of carbon tetrachloride (CCl4)-induced antioxidant activity in 2-month-old rats was conducted by examining the levels of activities of alanine aminotransaminase (ALT) and aspartate aminotransaminase (AST) and the antioxidant enzymes, including glutathione peroxidase (GSHPx) and catalase (CAT). Rats were divided into four groups, each containing six rats. The first group served as a control group. The second group was the CCl4 group. Group I and group II were treated orally with distilled water for 14 days respectively. Group III and Group IV were treated orally by WMAE and FMAE at oral doses of 50 mg/kg-day, respectively. Both WMAE and FMAE could reduce CCl4-induced toxicity, particularly hepatotoxicity, by suppressing ALT and AST activities, and increasing antioxidant enzyme activity. The studies demonstrate that both the fermented and wild-growing A. brasiliensis could protect the liver against CCl4-induced oxidative damage in rats.

The impact of urban areas on groundwater quality has become an emerging research field in hydrogeology. Urban subsurface infrastructures like sewer networks are often leaky, so untreated wastewater may enter the urban aquifer. The transport of wastewater into the groundwater is still not well understood under field conditions. In the research platform WASSER Leipzig (Water And Sewershed Study of Environmental Risk in Leipzig- Germany) the effects of leaky sewers on the groundwater quality are investigated. The research is focused on the occurrence and transport of so-called "xenobiotics" such as pharmaceuticals and personal care product additives. Xenobiotics may pose a threat on human health, but can also be considered a marker for an urban impact on water resources. A new test site was established in Leipzig to quantify mass fluxes of xenobiotics into the groundwater from a leaky sewer. Corresponding to the leaks which were detected by closed circuit television inspections, monitoring wells were installed up- and downstream of the sewer. Concentrations of eight xenobiotics (technical-nonylphenol, bisphenol-a, caffeine, galaxolide, tonalide, carbamazepine, phenazone, ethinylestradiol) obtained from first sampling programmes were found to be highly heterogeneous, but a relation between the position of the sampling points and the sewer could not be clearly identified. However, concentrations of sodium, chloride, potassium and nitrate increased significantly downstream of the sewer which may be due to wastewater exfiltration, since no other source is known on the water flowpath from the upstream to the downstream wells. Because of the highly heterogeneous spatial distribution of xenobiotics at the test site, a monitoring concept was developed comprising both high-resolution sampling and an integral approach to obtain representative average concentrations. Direct-push techniques were used to gain insight into the fine-scale spatial distribution of the target compounds

algizides (high amount of extracellular microcystins), - sandy material with low shares of clay and silt (little adsorption), - low temperatures (delayed biodegradation), - anoxic conditions (delayed biodegradation), - missing clogging layer or "schmutzdecke" (little bacteria), - no previous contact to microcystins (non adapted bacteria). It is therefore the aim of a new project financed by the KompetenzZentrum Wasser Berlin (KWB) to focus on these critical circumstances in order to find out how to optimise artificial recharge and bank filtration regarding microcystin elimination.

, Using a field-theoretic approach, we derive the exact low-density ("virial") expansion of a binary mixture of positively and negatively charged hard spheres (two-component hard-core plasma, TCPHC). The free energy obtained is valid for systems where the diameters d_+ and d_- and the charge valences q_+ and q_- of positive and negative ions are unconstrained, i.e., the same expression can be used to treat dilute salt solutions (where typically d_+ ~ d_- and q_+ ~ q_-) as well as colloidal suspensions (where the difference in size and valence between macroions and counterions can be very large). We also discuss some applications of our results. Eine der Faustregeln der Kolloid- und Oberflächenphysik ist, dass die meisten Oberflächen geladen sind, wenn sie mit einem Lösungsmittel, normalerweise Wasser, in Kontakt treten. Dies ist zum Beispiel bei ladungsstabilisierten Kolloidalen Suspensionen der Fall, bei denen die Oberfläche der Kolloidteilchen geladen ist (gewöhnlich mit einer Ladung von mehreren Hunderttausend Elementarladungen), oder bei Monoschichten ionischer Tenside, die auf einer Luft-Wasser Grenzfläche sitzen (wobei die wasserliebenden Kopfgruppen durch die Freisetzung von Gegenionen geladen werden), sowie bei Doppelschichten, die geladene phospholipide enthalten (wie Zellmembranen). In dieser Arbeit betrachten wir einige Modellsysteme, die zwar eine vereinfachte Fassung der Realität darstellen, von denen wir aber dennoch erwarten koennen, dass wir mit ihrer Hilfe einige physikalische Eigenschaften realer geladener Systeme (Kolloide und Elektrolyte) einfangen können.

meteorological forecasts produced by the European Centre for Medium-Range Weather Forecasts (ECMWF) to estimate (with a 2-day lead time) potential storm surges due to cyclone or general storm events. Departure between model and altimeter-derived values, in particularly wind, are investigated and discussed. The qualitative agreement is satisfactory; the maximum storm surge peak is correctly estimated by BSH but underestimated by JRC due to insufficient wind forcing. The wind speed of SARAL/AltiKa agrees well with the ECMWF model wind speed but is lower than the DWD model estimate.

the far future exceed the national assessment criteria for the handling of dredged material within coastal waterways more distinct than today. Therefore, adaptations of practices for the management of dredged material to higher particulate matter contaminations should be considered there in the medium or long-term perspective. On the one hand, e.g. the practices of depositing dredged- material within the water system might be adapted (BfG 2014). On the other hand, the implementation of remediation measures like those planned under the Water Framework Directive could mitigate the climate-induced increase of contaminants. However, before the planning of adaption measures begins, the respectively prevailing contamination status should be verified, as climate-induced changes of contaminant concentrations might be superimposed by direct anthropogenic activities, e.g. remediation measures to reduce contamination or construction works in waterways.

Mecikalski et al. (2010) are used to identify convectively active regions. Additionally, retrieved physical cloud properties of state-of-the-art cloud remote sensing algorithms such as the cloud top height, multilayer flags, cloud phase, optical depth and effective radius are employed. As soon as larger particles form, radar observations complement the satellite ones. Radar datasets are used in particular to observe the precipitation intensity and type, the vertical extension and structure of the convective cells. In the mature stage convective cells might start to produce lightning. The relation between the different observables and their suitability as predictors for the further convective development are discussed, e.g. strong updrafts in the developing phase are often followed by fast anvil spreading and intense precipitation in the mature phase. Threads and hazards due to heavy precipitation, hail, and wind gusts are estimated. Hering, A.

, and 2 longer ones, which include several short-term periods. Short-term periods spread from 1 to 3 months, whereas long-term periods indicate 2 and 5 years. The simulation results showed an acceptable agreement with the measurements. It was also found that the long-term periods had less deviation to the measurements than the short ones. This simplified method exhibited clear savings in computational time compared to the instationary simulations; in this case only 3 hours of computational time were needed for 5 years simulation period using the reference computer mentioned above. Further research is needed with respect to the limits of this linear approach, i.e. with respect to the frequency with which the set of steady simulations has to be updated due to significant changes in morphology and in turn in hydraulics. Yet, the preliminary results are promising, suggesting that the developed approach is very suitable for a long-term simulation of riverbed evolution. REFERENCES Olsen, N.R.B. 2014.

In Managed Aquifer Recharge (MAR) schemes the monitoring system, for both water quality and quantity issues, plays a key role in assuring that a groundwater recharge plant is really managed. Considering induced Riverbank Filtration (RBF) schemes, while the effect of the augmented filtration consists in an improvement of the quality and quantity of the water infiltrating the aquifer, there is in turn the risk for groundwater contamination, as surface water bodies are highly susceptible to contamination. Within the framework of the MARSOL (2014) EU FPVII-ENV-2013 project, an experimental monitoring system has been designed and will be set in place at the Sant'Alessio RBF well field (Lucca, Italy) to demonstrate the sustainability and the benefits of managing induced RBF versus the unmanaged option. The RBF scheme in Sant'Alessio (Borsi et al. 2014) allows abstraction of an overall amount of about 0,5 m3/s groundwater providing drinking water for about 300000 people of the coastal Tuscany. Water is derived by ten vertical wells set along the Serchio River embankments inducing river water filtration into a high yield (10-2m2/s transmissivity) sand and gravel aquifer. Prior to the monitoring system design, a detailed site characterization has been completed taking advantage of previous and new investigations, the latter performed by means of MOSAIC on-site investigation platform (UFZ). A monitoring network has been set in place in the well field area using existing wells. There groundwater head and the main physico-chemical parameters (temperature, pH, dissolved oxygen, electrical conductivity and redox potential) are routinely monitored. Major geochemical compounds along with a large set of emerging pollutants are analysed (in cooperation with IWW Zentrum Wasser, Germany) both in surface-water and ground-water. The experimental monitoring system (including sensors in surface- and ground-water) has been designed focusing on managing abstraction efficiency and safety at

From a sample of 119 Friesian calves, serologically typed for BoLA class I, 47 subjects were chosen expressing 9 different MHC types (A6, A6.9, A10, A11, A14, A15, A30, W16, M103) with the same age and reared in the same farm conditions. The animals were s.c. injected with a water in oil suspension of killed M. bovis and the treatment was repeated two days later. Before the treatment and 21 days later, calves were bled and on PBM (peripheral blood mononuclear leucocytes) were performed the following tests: 1. Lymphocyte Stimulation with bovine and avian PPDs (Purified protein derivative of Mycobacterium bovis and Mycobacterium avium, respectively). 2. Phagocytic activity towards M. bovis. 3. Class II molecules expression on cell surface. 4. Percentage of leucocyte populations and subpopulations. In the in vitro Lymphocyte Stimulation test, all the animals and classes were responders. Animals bearing A10 BoLA class I presented c.p.m. (counts per minute) and index values higher than the other cattle; these values were significantly positively related both to bovine and avian PPDs (P < .01). By variance analysis A14 BoLA type showed a slight positive significant correlation with more efficient phagocytic activity. BoLA class I type did not seem to significantly affect percentage of class II positive cells and leucocyte percentages on PBM.
