    In the last decade, significant interest has emerged to better understand the links between the foreland basin evolution and the erosion history of the Alps. For this, the European Alps are indeed a well-suited study region since the hinterland and the Swiss Molasse basin erosion rates and timing were extensively studied using basin analysis, and low-temperature thermochronology 1-4,5,6. However, the driving mechanisms for the post-Miocene erosion of the Swiss Molasse basin remains controversial, and several papers discuss whether global climatic changes1 or local variations of base level7,8,9 have controlled the erosion of the basin. With this study, we add quantitative constraints on the late-stage history of the basin by presenting new AFT and AHe dataset (respectively 16 and 19 samples) from two boreholes located ~30 km apart from each other, one located close to the center (Sonnengarten, depth of 3500 m) and one located to the North (Benken, depth of 100 m) of the basin. The data are derived from Triassic to Pliocene sand deposits as well as the underlying gneissic basement rocks and both AFT and AHe results are ranging from Pliocene to Triassic ages. The two dataset present very different age patterns which make the direct interpretation difficult. Therefore, thermal models using the QTQt software10,11 have been performed. This software is capable to evaluate cooling rates and timing using multiple samples from a single borehole. To test the robustness of the simulations, several runs for each borehole based on different data sets were performed, and showed some discrepancies between the resulting thermal histories. We provide, based on the simulations results, the most probable erosion estimates which are in the same range as the ones proposed in previous studies in the basin. For the borehole Benken, we reproduce a long and slow erosion phase starting at 23 Ma, with an overall estimate of the amount of eroded sediments ranging between 1.2 to 2 km. For the

    The stratigraphies of foreland basins have been related to orogeny, where continent–continent collision causes the construction of topography and the downwarping of the foreland plate. These mechanisms have been inferred for the Molasse basin, stretching along the northern margin of the European Alps. Continuous flexural bending of the subducting European lithosphere as a consequence of topographic loads alone would imply that the Alpine topography would have increased at least between 30 Ma and ca. 5–10 Ma when the basin accumulated the erosional detritus. This, however, is neither consistent with observations nor with isostatic mass balancing models because paleoaltimetry estimates suggest that the topography has not increased since 20 Ma. Here we show that a rollback mechanism for the European plate is capable of explaining the construction of thick sedimentary successions in the Molasse foreland basin where the extra slab load has maintained the Alpine surface at low, but constant, elevations.

    The main aim of this project is the preparation of a specific data base of geothermal properties for typical rocks of the Swiss Molasse Basin (depth interval 0-500 m). The project includes the development of a new laboratory tool for efficient heat capacity measurements on rock samples, numerous new measurements of geothermal rock properties in the laboratory and calculation of such data from geophysical borehole logs. In the geographical area under review, 282 rock samples, mainly from deep boreholes, were analyzed with the successfully calibrated new heat capacity device and conventional thermal conductivity measuring techniques (cuttings and cores). Based on sonic and density log data from exploration wells, 374 additional data points were generated. This new data base characterizes in detail the six main lithological rock types in the three Molasse groups OSM, OMM and USM within the Swiss Plateau Molasse. The statistical evaluation of all data illustrates the regional variation of the petrophysical and geothermal parameters. For most data groups bulk rock density and thermal conductivity increase, whereas heat capacity decreases in the direction towards the Alpine front. Thermal conductivity shows a distinct increase with depth. Based on this new information and with the aid of the evaluation software tool SwEWS, the costs of planned geothermal installations can be optimized thanks to more precise heat extraction simulations with existing software packages like COSOND, TRNSYS, EWS or WPcalc.

    We propose three partly unrelated stages in the geodynamic evolution of the Alps and the sedimentary response of the Molasse Basin. The first stage comprises the time interval between ca. 35 and 20 Ma and is characterized by a high ratio between rates of crustal accretion and surface erosion. The response of the Molasse Basin was a change from the stage of basin underfill (UMM) to overfill (USM). Because the response time of erosional processes to crustal accretion and surface uplift lasts several millions of years, the orogen first experienced a net growth until the end of the Oligocene. As a result, the Molasse basin subsided at high rates causing the topographic axis to shift to the proximal basin border and alluvial fans to establish at the thrust front. During the Aquitanian, however, ongoing erosion and downcutting in the hinterland caused sediment discharge to the basin to increase and the ratio between the rates of crustal accretion and surface erosion to decrease. The result was a progradation of the dispersal systems, and a shift of the topographic axis towards the distal basin border. The second stage started at ca. 20 Ma at a time when palaeoclimate became more continental, and when the crystalline core became exposed in the orogen. The effect was a decrease in the erosional efficiency of the Swiss Alps and hence a reduction of sediment discharge to the Molasse Basin. We propose that this decrease in sediment flux caused the Burdigalian transgression of the OMM. We also speculate that this reduction of surface erosion initiated the modification of Alpine deformation from vertically- to mainly horizontally directed extrusion (deformation of the Southern Alps, and the Jura Mountains some Ma later). The third stage in the geodynamic development was initiated at the Miocene/Pliocene boundary. At that time, palaeoclimate possibly became wetter, which, in turn, caused surface erosion to increase relative to crustal accretion. This change caused the Alps to

    The Alpine peripheral foreland basin formed during Eocene collision of the lower, European plate and the upper, Adriatic plate. Two marine to continental megasequences fill the basin. The transition form deep marine to continental deposits of the first megasequence at the Early - Late Oligocene boundary has been related to a change from predominant horizontal to vertical movements in the core of the orogenic wedge. The second megasequence is, however, poorly understood, and different models have been put forward. I present an alternative explanation for the development of this second megacycle, based on an analysis of the Subalpine Molasse thrust belt east of the Rhine river (Ortner et al., 2015). The main characteristics of the Subalpine Molasse thrust belt are: 1) A frontal anticline/thrust started to develop during deposition of the older, marine portion of the second megasequence. Structures continued to grow throughout deposition of the younger, continental part of the megasequence. Structural growth is documented by growth strata. 2) The thrusts in the Subalpine Molasse evolved in a break-back sequence. 3) The amount of shortening during depositon of the second megasequence reduces from 40-50 km near the Rhine valley to zero in the east in the Salzburg area. The onset of the second megasequence in the foreland north of the Subalpine Molasse thrust belt is characterized by an angular unconformity documenting a tilt of the foreland toward the orogen, and therefore ongoing flexure of the lower plate. East of the eastern end of the Subalpine Molasse thrust belt, the deposits of the second megasequence are in a horizontal position, lower plate flexure had stopped. In the internal part of the Alpine orogenic wedge, shortening, exhumation and E-directed stretching of the Tauern Window as a consequence of escape tectonics was active. Most probably shortening was transferred from the Alpine front into the zone of lateral escape, causing the break-back thrust sequence

    The main aim of this project is the preparation of a data base of geothermal properties for typical rocks of the Swiss Molasse Basin (depth interval 0 to 500 m) combined with a simple evaluation software tool. The project includes the integration of numerous laboratory measurements of thermal conductivity and heat capacity with additional data calculated from geophysical borehole logs. Within the study area, 380 additional data points were generated with sonic and density log data from exploration wells. This new data base characterises in detail the 6 main lithological rock types in the 3 Molasse groups 'OSM', 'OMM' and 'USM' within the Swiss Plateau Molasse. The statistical evaluation of all data illustrates the regional variation of the petrophysical and geothermal parameters. The software tool SwEWS allows the analysis of a specific depth profile defined by the user. Based on the input for the stratal model the programme calculates the geothermal parameters for each horizon together with a temperature profile. The results can be analysed in various tables and a graphic display. For further use the data can also be exported as an ASCII file. Based on this new information and with the aid of the evaluation software tool SwEWS the costs of planned geothermal installations can be optimised by more precise heat extraction simulations with existing software packages like COSOND, TRNSYS, EWS or WPcalc.

    Due to a wealth of geological and thermochronology data the northern foreland basin of the European Alps is an ideal natural laboratory for understanding the dynamics of foreland basins and their interaction with surface and geodynamic processes. The northern foreland basin of the Alps has been exhumed since the Miocene. The timing, rate and cause of this phase of exhumation are still enigmatic. We compile all available thermochronology and organic maturity data and use a new thermal history model, PyBasin, to quantify the rate and timing of exhumation that can explain these data. In addition we quantify the amount of tectonic exhumation using a new kinematic model for the part of the basin that is passively moved above the detachment of the Jura Mountains. Our results show that the vitrinite reflectance, apatite fission track data and cooling rates show no clear difference between the thrusted and folded part of the foreland basin and the undeformed part of the foreland basin. The undeformed plateau Molasse shows a high rate of cooling during the Neogene of 40 to 100 °C, which is equal to >1.0 km of exhumation. Calculated rates of exhumation suggest that drainage reorganization can only explain a small part of the observed exhumation and cooling. Similarly, tectonic transport over a detachment ramp cannot explain the magnitude, timing and wavelength of the observed cooling signal. We conclude that the observed cooling rates suggest large wavelength exhumation that is probably caused by lithospheric-scale processes. In contrast to previous studies we find that the timing of exhumation is poorly constrained. Uncertainty analysis shows that models with timing starting as early as 12 Ma or as late as 2 Ma can all explain the observed data.

    The Middle Miocene Upper Freshwater Molasse sediments represent the last cycle of clastic sedimentation during the evolution of the North Alpine Foreland Basin. They are characterized by small-scale lateral and temporal facies changes that make intra-basin stratigraphic correlations at regional scale difficult. This study provides new U-Pb zircon ages as well as revised 40Ar/39Ar data of volcanic ash horizons in the Upper Freshwater Molasse sediments from southern Germany and Switzerland. In a first and preliminary attempt, we propose their possible correlation to other European tephra deposits. The U-Pb zircon data of one Swiss (Bischofszell) and seven southern German (Zahling, Hachelstuhl, Laimering, Unterneul, Krumbad, Ponholz) tuff horizons indicate eruption ages between roughly 13.0 and 15.5 Ma. The stratigraphic position of the Unterneul and Laimering tuffs, bracketing the ejecta of the Ries impact (Brockhorizon), suggests that the Ries impact occurred between 14.93 and 15.00 Ma, thus assigning the event to the reversed chron C5Bn1r (15.032-14.870 Ma) which is in accordance with paleomagnetic evidence. We combine our data with published ages of tuff horizons from Italy, Switzerland, Bavaria, Styria, Hungary, and Romania to derive a preliminary tephrochronological scheme for the Middle Miocene in Central Europe in the age window from 13.2 to 15.5 Ma. The scheme is based on the current state of knowledge that the Carpathian-Pannonian volcanic field was the only area in the region producing explosive calc-alkaline felsic volcanism. This preliminary scheme will require verification by more high-quality ages complemented by isotopic, geochemical and paleomagnetic data.

    Document available in extended abstract form only. Full text of publication follows: The design of geological repositories for radioactive waste responds to the requirements of technical feasibility and long-term safety in the context of a specific geological setting. An important aspect of the geological setting is the primary stress field. To a large extent the stress state controls repository induced effects such as the excavation damage zone and the associated potential changes in the waste isolation properties of the host rock. Therefore the measurement of the stress state receives some attention where the site selection for geological repositories focuses onto relatively weak host rocks such as clay-stones and marly shales that tend to develop a significant excavation damage zone. Measurements of the minimum stress magnitudes in a recently drilled geothermal well in the Molasse Basin of northern Switzerland have yielded a stress profile reaching from 592 m to 1455 m depth. It straddles several rock units and includes the top of the crystalline basement. The sedimentary sequence consists of Marine limestones, shales and marls unconformably covered by Tertiary rocks of the Molasse. In other parts of the basin the evaporitic rocks of the Triassic Muschelkalk formation at the base of the sedimentary layer served as a regional detachment and enabled thin skinned thrusting and the formation of the Jura Fold and Thrust Belt in the Late Miocene. The stress measurements have been performed in the open hole by Mini-frac tests. The method uses a double packer system to isolate a one meter long interval of the borehole that is then pressurized at high injection rates up to the breakdown of the formation. Repeated pressurization of the interval allows to determine the stress that acts on the newly created fracture. The total injected volume during such a test is in the range of a few litres and the size of the fracture that extends from the borehole normal to the minimum

    Faults play an essential role in geothermal exploration. The prediction of potential fluid pathways in urban Munich has been started with the interpretation of a 3-D seismic survey (170 km2) that was acquired during the winter of 2015/2016 in Munich (Germany) within the Bavarian Molasse Basin. As a part of the research project GeoParaMoL*, we focus on the structural interpretation and retro-deformation analysis to detect sub-seismic structures within the reservoir and overburden. We explore the hydrothermal Malm carbonate reservoir (at a depth of 3 km) as a source of deep geothermal energy and the overburden of Tertiary Molasse sediments. The stratigraphic horizons, Top Aquitan, Top Chatt, Top Bausteinschichten, Top Lithothamnien limestone (Top Eocene), Top and Base Malm (Upper Jurassic), together with the detailed interpretation of the faults in the study area are used to construct a 3-D geological model. The study area is characterised by synthetic normal faults that strike parallel to the alpine front. Most major faults were active from Upper Jurassic up to the Miocene. The Munich Fault, which belongs to the Markt-Schwabener Lineament, has a maximum vertical offset of 350 metres in the central part, and contrary to previous interpretation based on 2-D seismic, this fault dies out in the eastern part of the area. The south-eastern part of the study area is dominated by a very complex fault system. Three faults that were previously detected in a smaller 3-D seismic survey at Unterhaching, to the south of the study area, with strike directions of 25°, 45° and 70° (Lüschen et al. 2014), were followed in to the new 3-D seismic survey interpretation. Particularly noticeable are relay ramps and horst/graben structures. The fault with a strike of 25° ends in three big sinkholes with a maximum vertical offset of 60 metres. We interpret this special structure as fault tip horsetail-structure, which caused a large amount of sub-seismic deformation. Consequently, this

    Detailed knowledge of the geothermal properties (thermal conductivity and specific heat capacity) of the undergorund becomes more and more important with increasing exploitation of geothermal resources by deep vertical borehole heat exchangers or by seasonal storage installations. For this pilot study all existing thermal conductivity data of the Swiss Molasse were compiled and supplemented with new laboratory measurements on core and cutting samples from deep wells (2.5 to 3.0 W/mK). In a second step top-to-bottom thermal conductivity profiles were calculated from geophysical well logs. These profiles show a clear dependence on lithology and variations in thermal conductivity of up to 1 W/mK over 50-200 m thick intervals. In clay-rich lithofacies thermal conductivity is only slightly dependent on the sedimentary architecture, whereas, in sandy facies obvious distinctions are possible. The modelling of a theoretical 750 m long vertical borehole heat exchanger shows that the potential quality of extractable heat increases or decreases by up to 20% by varying the thermal conductivity with only {+-}0.5 W/mK.

    The knowledge of the contemporary in situ stress state is a key issue for safe and sustainable subsurface engineering. However, information on the orientation and magnitudes of the stress state is limited and often not available for the areas of interest. Therefore 3-D geomechanical-numerical modelling is used to estimate the in situ stress state and the distance of faults from failure for application in subsurface engineering. The main challenge in this approach is to bridge the gap in scale between the widely scattered data used for calibration of the model and the high resolution in the target area required for the application. We present a multi-stage 3-D geomechanical-numerical approach which provides a state-of-the-art model of the stress field for a reservoir-scale area from widely scattered data records. Therefore, we first use a large-scale regional model which is calibrated by available stress data and provides the full 3-D stress tensor at discrete points in the entire model volume. The modelled stress state is used subsequently for the calibration of a smaller-scale model located within the large-scale model in an area without any observed stress data records. We exemplify this approach with two-stages for the area around Munich in the German Molasse Basin. As an example of application, we estimate the scalar values for slip tendency and fracture potential from the model results as measures for the criticality of fault reactivation in the reservoir-scale model. The modelling results show that variations due to uncertainties in the input data are mainly introduced by the uncertain material properties and missing SHmax magnitude estimates needed for a more reliable model calibration. This leads to the conclusion that at this stage the model's reliability depends only on the amount and quality of available stress information rather than on the modelling technique itself or on local details of the model geometry. Any improvements in modelling and increases

    The structural evolution of faults in foreland basins is linked to a complex basin history ranging from extension to contraction and inversion tectonics. Faults in the Upper Jurassic of the German Molasse Basin, a Cenozoic Alpine foreland basin, play a significant role for geothermal exploration and are therefore imaged, interpreted and studied by 3D seismic reflection data. Beyond this applied aspect, the analysis of these seismic data help to better understand the temporal evolution of faults and respective stress fields. In 2009, a 27 km2 3D seismic reflection survey was conducted around the Unterhaching Gt 2 well, south of Munich. The main focus of this study is an in-depth analysis of a prominent v-shaped fault block structure located at the center of the 3D seismic survey. Two methods were used to study the periodic fault activity and its relative age of the detected faults: (1) horizon flattening and (2) analysis of incremental fault throws. Slip and dilation tendency analyses were conducted afterwards to determine the stresses resolved on the faults in the current stress field. Two possible kinematic models explain the structural evolution: One model assumes a left-lateral strike slip fault in a transpressional regime resulting in a positive flower structure. The other model incorporates crossing conjugate normal faults within a transtensional regime. The interpreted successive fault formation prefers the latter model. The episodic fault activity may enhance fault zone permeability hence reservoir productivity implying that the analysis of periodically active faults represents an important part in successfully targeting geothermal wells.

    be dealt with by conditioning the top surface of the model to "trend" towards the present day topographic profile along the cross section, in a crude proxy for erosion. In the case of the Jura-Molasse fold thrust belt, the basal boundary condition also very likely plays a significant role in the thrust-belts evolution. A large, extra component of regional basement uplift appears to have occurred across the Swiss Molasse and Jura, according to geological indicators like the present day position and altitude of Miocene marine sedimentary units. In general, the Jura-Molasse example is thus highly instructive in the difficulties of incorporating all necessary geological realities into a numerical forward model of a specific geological situation. Despite all this, we find that using a numerical forward model of minimal complexity (three rheological layers as opposed to at least eight suggested by the rheological stratigraphy of the chain) with no pre-existing weaknesses to predetermine locations of faults, we easily achieve a good facsimile of at least the distribution of shortening across the Jura-Molasse system. Localisation of shortening occurs on approximately similar numbers of major faults as in reality, and their positions in the section are also broadly similar to those known from field data. Dynamic parameters like stress evolution, recovered from the model, are also in broad agreement with paleostress level indicators from the Jura-Molasse. In our first experiments, we have used a grid of variations of basic mechanical parameters (friction of basal layer and strength of main, limestone unit) to map the model responses over a range of parameter space and search for the best fitting response. The potential to automate such searches and continuously optimise the fit to real data is clearly also there, given sufficient computer capacity. Hence, we can envisage a time when cross section balancing will be combined with and improved by a subsequent stage of forward

    Fishscale shales (Schoeneck Formation) is an important parent rock of petroleum in prealpine molasse. Two different formation models are discussed, i.e. deposition and accumulation of organic matter (a) in a stagnating basin and (b) in a buoyancy zone. Both models were derived from samples, but they provide no information on the lithological and geochemical characteristics of complete fishscale shale sequences. This investigation focused on the vertical and lateral sedimentary development and the diagenetic changes of organic matter in the fishscale shales of upper Austria. Additionally, organic-geochemical data were used for validating the two deposition models.

  1. Geomorphological response of a landscape to long-term tectonic and glacial processes: the upper Rhône basin, Central Swiss Alps

    The Rhône River in the Central Swiss Alps drains a 5380 km2 large basin that shows a high spatial variability of bedrock lithology, exhumation rate, glacial conditioning and climate. All of these factors were recently discussed to control erosion rates in orogenic settings in general, and particularly in the Alps (e.g. Wittmann et al. 2007, Vernon et al. 2008, Norton et al. 2010a). Thanks to various and densely distributed data, the upper Rhône basin located between the Aar massif and Lake Geneva is a suitable natural laboratory to analyze the landscape's geomorphological state and controlling factors at a basin-scale. In this study, we extract geomorphological parameters along the channels of ca. 50 tributary basins of various sizes that contribute to the sediment budget of the Rhône River either through sediment supply by torrents or debris flows. Their catchments are located in either granitic basement rocks (External Massifs), oceanic meta-sedimentary and ophiolitic rocks (Penninic nappes) or fine-grained continental-margin sediments (Helvetic nappes). The analysis of longitudinal river profiles from DEMs and slope/area relationships show that all tributary rivers within the Rhône basin are in topographic transient state that is expressed by mainly convex or concave-convex channel shapes with several knickpoints of either tectonic-lithological or glacial origin. Furthermore, the frequency distribution of elevations (hypsometry) along the river channel allows identifying glacially inherited morphologies and the recent erosional front. The combination of those different geomorphological data yields to a categorization of the tributary rivers into three endmember groups: (1) streams with highly convex profiles, testifying to a strong glacial inheritance, (2) concave-convex channels with several knickzones and inherited morphologies of past glaciations, (3) predominantly concave, relatively steep rivers with minor knickpoints and inner gorges. Assuming that

    Non-linear hydrological behavior of small mountainous watersheds is often attributed to variable streamflow contributions from different landscape units that differ in subsurface properties, vegetation cover and land use. Within this concept, the role of landscape can be seen as that of a filter, translating hydro-climatic drivers into particular streamflow signals - such as discharge rates or water quality. Our research addresses the question of how hydrologic connectivity between the relevant landscape units evolves during storm events and droughts at headwater catchments and seeks to establish a general framework of interdisciplinary interest (e.g., ecology and climate science). We focus on the description of groundwater flow on the local and regional scale, since groundwater - surface water - interaction in the valley bottoms, transport mechanisms of nutrients within hyporheic zones, and groundwater flow dynamics in the shallow subsurface have all been identified as important processes in describing hydrologic catchment response and streamflow composition. Our field-based study takes place in the pre-Alpine Rietholzbach research catchment (~ 3 sq km) in the headwaters of the Thur basin in NE Switzerland. We investigated the effects of landscape properties on river water quality and catchment hydrology over a two-year period. The Rietholzbach research catchment is equipped with a meteorological station, a weighting lysimeter, 20 piezometers, 3 stream gauging stations and various soil moisture and temperature probes, which provide continuous, high-frequency measurements of atmospheric and hydrometric data. These measurements are used in combination with hydro-chemistry data to determine groundwater residence times and streamflow composition. The installed setup facilitates the investigation of annual, inter-seasonal as well as short-term dynamics of water flow and its links to associated parameters describing atmospheric, surface and subsurface properties. We

    Cane molasses, most of which is imported, is used as a raw material for production of baker's yeast (Saccharomyces cerevisiae) in Japan. On the other hand, beet molasses is scarcely used for this purpose, but it can be of great advantage to cane molasses because it is domestically produced in relatively high amounts as a by-product of beet sugar processing. However, the yield of baker's yeast is sometimes low with Japanese beet molasses compared to imported cane molasses. For the production of baker's yeast with Japanese beet molasses, we evaluated S. cerevisiae strains, including industrial and laboratory strains, to group them according to the growth profile on beet and cane molasses. To discuss the factors affecting growth, we further analyzed the major compounds in both types of molasses. Beet molasses seems to contain compounds that promote the growth of beet molasses-favoring strains rather than inhibit the growth of cane molasses-favoring strains. It was assumed that α-amino acid was one of the growth promotion factors for beet molasses-favoring strains. Copyright © 2013 The Society for Biotechnology, Japan. Published by Elsevier B.V.

    Full Text Available Abstract Background & aim: Dextran is a polysaccharide consisting of glucose monomers that are widely used in medicine as a blood volume extender. The aim of this study was to produce dextran from cane molasses using Leuconostoc mesenteroides bacteria. Methods: In this experimental study, for bacterial growth and dextran production, sugarcane molasses was added to the culture medium at different concentrations. Dextran sedimentation was obtained by shaking and centrifugation by adding ethanol after 48 hours. Response surface design was used for qualitative identification of the polarization of dextran and statistical analysis methods. Results: After assessing the separation and interactive effects of the parameters on the optimum amount of dextran produced from sugarcane molasses as 50 g, 35 º C and 5/8 = pH , the Dextran produced was more than 82 g/l. The correlation of the computational model for the dextran produced was 99.5%, which indicated excellent agreement with the experimental and computational models of high accuracy. Conclusion: Dextran produced by Leuconostoc mesenteroides bacteria and sugarcane molasses as substrate, is a cheap and affordable compared to current methods of dextran production. In addition to producing a clinical product, the molasses pollution could be dramatically decreased. Key words: Dextran, Molasses, Leuconostoc Mesenteroides

    Full Text Available Abstract Background Sugar beet molasses is a viscous by-product of the processing of sugar beets into sugar. The molasses is known to contain sucrose and raffinose, a typical trisaccharide, with a well-established structure. Although sugar beet molasses contains various other oligosaccharides as well, the structures of those oligosaccharides have not been examined in detail. The purpose of this study was isolation and structural confirmation of these other oligosaccharides found in sugar beet molasses. Results Four oligosaccharides were newly isolated from sugar beet molasses using high-performance liquid chromatography (HPLC and carbon-Celite column chromatography. Structural confirmation of the saccharides was provided by methylation analysis, matrix-assisted laser desorption/ionaization time of flight mass spectrometry (MALDI-TOF-MS, and nuclear magnetic resonance (NMR measurements. Conclusion The following oligosaccharides were identified in sugar beet molasses: β-D-galactopyranosyl-(1- > 6-β-D-fructofuranosyl-(2 1-α-D-glucopyranoside (named β-planteose, α-D-galactopyranosyl-(1- > 1-β-D-fructofuranosyl-(2 1-α-D-glucopyranoside (named1-planteose, α-D-glucopyranosyl-(1- > 6-α-D-glucopyranosyl-(1 2-β-D-fructofuranoside (theanderose, and β-D-glucopyranosyl-(1- > 3-α-D-glucopyranosyl-(1 2-β-D-fructofuranoside (laminaribiofructose. 1-planteose and laminaribiofructose were isolated from natural sources for the first time.

    Accurate reconstruction of the final sea retreat from the North Alpine Foreland Basin (NAFB) during the Burdigalian (Early Miocene) is hampered by a lack of reliable age constraints. In this high resolution magnetostratigraphic study we try to solve a significant age bias for the onset of the Upper Freshwater Molasse (OSM) deposition in the neighboring S-German and Swiss Molasse Basins. We measured > 550 samples from eleven drill cores covering the transition from marine to brackish to freshwater environments in the S-German Molasse Basin. Based on combined bio-, litho- and magnetostratigraphic constraints, the composite magnetostratigraphic pattern of these cores provides two reasonable age correlation options (model 1 and 2). In model 1, the base of the brackish succession lies within Chron C5Cr ( 16.7-17.2 Ma), and the onset of OSM deposition has an age of 16.5 Ma. Correlation model 2 suggests the transition to brackish conditions to be within C5Dr.1r ( 17.7-17.5 Ma), and yields an age around 16.7 Ma for the shift to the OSM. Most importantly, both models confirm a much younger age for the OSM base in the study area than previously suggested. Our results demonstrate a possible coincidence of the last transgressive phase (Kirchberg Fm) with the Miocene Climatic Optimum (model 1), or with the onset of this global warming event (model 2). In contrast, the final retreat of the sea from the study area is apparently not controlled by climate change. Supplementary material B.

From the first measurement after irradiation at the Triga Mark reactor (VTT), the concentration of more than 15 elements is reported. The almost constant elemental composition shows that they can be used equally for different purposes as animal foodstuff and for the manufacture of biotechnological products. This work is part of a research project developed in order to establish a complete characterization of Cuban sugar molasses. (author). 7 refs., 2 tabs

    Sedimentary study at outcrop and quarry exposures of distal alluvial deposits in the upper part of the Lower Freshwater Molasse ('Aquitan') has revealed four principal facies. The same facies may also be recognised in boreholes (Langenthal, Weiach, Schafisheim) penetrating the continental succession. These facies make up distinct sediment bodies or 'architectural elements'. Each architectural element may be assigned to a particular depositional setting: Meander Belt RG (MB); Crevasse Splays and Crevasse Channels DFR (CS), Levees and Distal Splays UW (LS), Overbank, Paleosols and Swamps UPS (OPS) and Lacustrine LAK (LAC). Meander belt sandstones in the distal Lower Freshwater Molasse reflect the occurrence of two types of mixed load channels. Architectural modelling permits consideration of the distal Lower Freshwater Molasse in terms of a sandy framework, comprising the channel sandstone bodies, each in contact with their associated crevasse splay and crevasse channel sandstones, and a muddy-silty matrix consisting of interbedded floodplain sediments. Comparison with the morphologies of modern alluvial systems suggests that channel sandstone bodies in the Lower Freshwater Molasse are likely to show greater longitudinal continuity, greater width and a higher degree of interconnectedness in an upstream direction. Conversely, primary depositional porosities and permeabilities of the sandstone units are likely to decrease downstream towards more distal areas in the east and at the northern margin of the basin, although regional differences in tectonic style and diagenesis will also exert a major control on the petrophysical and hydrological properties in any given area.

    Water demand in Tokyo has increased rapidly. Because of the scarcity of water supply sources within the city, Tokyo is dependent on the water from other prefectures. Recycling of municipal effluent is an effective means of coping with water shortage in Tokyo. We have studied the radiation treatment of waste water for recycling. In this paper, the radiation decomposition methods for fading color of molasses pigment in the effluent from the sewage treatment plant and in the food industry wastwater were reported. The refractory organic substances (molasses pigment) in samples were degraded by gamma irradiation. The COD values decreased and the dark brown color faded with increasing dosage. The high molecular weight components of molasses pigment were degraded to lower molecular weight substances and were decomposed finally to carbon dioxide. The organic acids, such as formic acid, acetic acid, oxalic acid, citric acid and succinic acid were measured as intermediates of radiolytic decomposition. When we added hydrogen peroxide in samples to the gamma irradiation process, the dark brown color of molasses pigment faded with greater efficiency. (author).

    Alcohol production rate decreases as the concentration of bacterial contaminants increases. In complex medium, such as beet molasses, an alternative mechanism can be used by homofermentative lactic bacteria (Lactobacillus casei). Lactic acid and associated products, especially acetic acid, are liberated into the medium. The inhibition induced by these metabolites was reinforced by the presence of viable lactobacilli.

    Water demand in Tokyo has increased rapidly. Because of the scarcity of water sources within the city, Tokyo is dependent on water from other prefectures. Recycling of municipal effluent is an effective means of coping with water shortage in Tokyo. We have studied the radiation treatment of waste water for recycling. The degradation of molasses pigments in waste water from yeast factory by radiation was investigated. The dialyzed molasses pigments and non-dialyzed samples in waste waters were compared in chromaticity, UV absorption, color different and COD. The dialysis and fractionation by permeable membrane were carried out with Seamless Cellulose tubing (Union Carbide Corporation) and spectra/Por membrane (Spectrum Medical Industries INC.) The TOC values decreased and the dark brown color faded with increasing dose. The high molecular weight components of molasses pigment were degraded to lower molecular weight substances and decomposed to carbon dioxide. The relationships between the value of chromaticity/TOC and molecular weight of molasses pigments were obtained by radiation. (author)

    Water demand in Tokyo has increased rapidly. Because of the scarcity of water supply sources within the city, Tokyo is dependent on the water from other prefectures. Recycling of municipal effluent is an effective means of coping with water shortage in Tokyo. We have studied the radiation treatment of waste water for recycling. In this paper, the radiation decomposition methods for fading color of molasses pigment in the effluent from the sewage treatment plant and in the food industry wastwater were reported. The refractory organic substances (molasses pigment) in samples were degraded by gamma irradiation. The COD values decreased and the dark brown color faded with increasing dosage. The high molecular weight components of molasses pigment were degraded to lower molecular weight substances and were decomposed finally to carbon dioxide. The organic acids, such as formic acid, acetic acid, oxalic acid, citric acid and succinic acid were measured as intermediates of radiolytic decomposition. When we added hydrogen peroxide in samples to the gamma irradiation process, the dark brown color of molasses pigment faded with greater efficiency. (author)

    Sugar cane molasses is a commonly used ingredient in several food products. Contrasting reports suggest that molasses may have potential adverse or beneficial effects on human health. However, little evidence exists that examines the effects of molasses on the different physiological systems. This study investigated the effects of sugar cane molasses on various physiological systems using in vivo and in vitro methods. Molasses was administered orally to BALB/c, male mice and animals were randomly assigned into either a treatment or control group. General physiological changes, body weight and molasses intake of animals were monitored. At the end of the exposure period, collected blood samples were evaluated for potential toxicity using plasma biomarkers and liver enzyme activity. Immunised treated and untreated mice were evaluated for antibody titre to determine the effect of molasses on the immune response. To investigate the impact of molasses on testicular steroidogenesis, testes from both treated and control groups were harvested, cultured and assayed for testosterone synthesis. Findings suggest that fluid intake by molasses-treated animals was significantly increased and these animals showed symptoms of loose faeces. Molasses had no significant effect on body weight, serum biomarkers or liver enzyme activity ( P >0.05). Immunoglobulin-gamma anti-antigen levels were significantly suppressed in molasses-treated groups ( P =0.004). Animals subjected to molasses exposure also exhibited elevated levels of testosterone synthesis ( P =0.001). Findings suggests that molasses adversely affects the humoral immune response. The results also promote the use of molasses as a supplement to increase testosterone levels.

    V. A. Afanas’ev

    2015-01-01

    Full Text Available A technology for wet pressing of carbohydrate-vitamin-mineral additives with increase in content of molasses was developed. In the UVMD wet pressing with increased molasses content two options for finished additives were considered: briquettes and pellets. In the first phase of work pilot batch of feed supplement for cattle was prepared: 25 % of rapeseed meal; 10 % of soybean meal; 4 % of feeding oil; 51 % of molasses; 5 % of lime; 5 % of premix. It is established that satisfactory mixing occurs when entering the molasses up to 40 %. Further increase in molasses content causes deterioration of mixing. In the second phase a research at the choice of materials, providing hardening of molasses briquette was carried out. At the same time additives for cattle contained 30 ... 50 % of molasses, sunflower meal, wheat bran, beet pulp, tricalcium phosphate, salt, premix. 3 % of hydrated lime and zeolite and also 5 % of limestone flour were used as the cementitious materials in the preparation of pellets with the molasses content of 40,0 %. Briquettes with 30 % and 50 % of molasses do not have sufficient strength. It has been established that when entering the 50 % of molasses and 3 % of hardeners countercurrent flow of material in the mixer stops, the mixture becomes viscous, of pasty consistency. Molasses briquettes had not hardened during storage, were soft and plastic. Briquettes containing 40,0 % of molasses and 3,0 % of hydrated or unhydrated lime were hard in comparison with briquettes containing other hardeners. With increasing input of hardeners up to 5 % molasses blocks were more solid and retained its shape.

    2016-01-01

    Full Text Available Molasses is an important by-product of sugar beet or sugar cane refining industry and it was one of the first sweeteners used in human nutrition. Sugar cane molasses has unique characteristics that can make it suitable for application in food industry, especially in confectionery and bakery products. On the other hand, sugar beet molasses has not had greater application in the human diet, primarily because of its strong smell and taste of the beet, which makes it unattractive for consumption. Since recent investigations showed that sugar beet molasses can be used as a hypertonic solution in osmotic dehydration of different materials of plant and animal origin, the objective of this work was to review recently studied sugar beet molasses in terms of its applications in osmotic dehydrations of fruits and vegetables. Previous studies showed that sugar beet molasses is an excellent medium for osmotic dehydration of fruits and vegetables (apple, carrot, plum, etc. primarily due to a high content of dry matter (80%, w/w and specific nutrient content. An important advantage of using sugar beet molasses as a hypertonic solution is an enrichment of the dehydrated material in minerals and vitamins, which penetrate from molasses into the plant tissue. Concentration of sugar beet molasses solution and immersion time had the biggest influence on the process of osmotic dehydration of fruit and vegetables, while the temperature of the solution was the least influential parameter. The effect of immersion time on the kinetics of osmotic dehydration in sugar beet molasses increases with an increase in concentration of hypertonic solution. Fruit and vegetables dehydrated in sugar beet molasses had a higher dry matter content compared to samples treated in sucrose solutions. Besides, application of sugar beet molasses in osmotic dehydration of fruits and vegetables had some other advantages such as lower cost of molasses compared to sugar and its liquid aggregate

    Sugar beet molasses is a raw material with high potential to be a functional ingredient in baked goods. This paper investigated the nutritional and functional properties of gluten-free cookies enriched with sugar beet molasses. At all enrichment levels and forms tested (liquid and dry), the addition of beet molasses improved the micronutrient pattern and antioxidative status of gluten-free cookies. The cookies prepared with molasses were significantly higher in potassium, magnesium, calcium, iron, betaine, total phenolics and DPPH radical scavenging abilities. Molasses contributed to wider spectra of phenolic compounds. The dominating phenolic compounds in the molasses-enriched cookies were catechin, ferulic, syringic and vanillic acid. Molasses also contributed to the presence of p-hydroxybenzoic acid in the cookies. Addition of molasses increased the content of hydroxymethyfurfural in the cookies, but not above values commonly reported for this product type. Molasses addition improved the overall acceptance of gluten-free cookies up to 30% enrichment level.

    2013-07-01

    Concentrated molasses (C5 molasses) from 2nd generation bioethanol plant has been investigated for enhancing productivity of manure based digesters. A batch study at mesophilic condition (35+- 1 deg C) showed the maximum methane yield from molasses as 286 LCH4/kgVS which was approximately 63% of the calculated theoretical yield. In addition to the batch study, co-digestion of molasses with cattle manure in a semi-continuously stirred reactor at thermophilic temperature (50+- 1 deg C) was also performed with a stepwise increase in molasses concentration. The results from this experiment revealed the maximum average biogas yield of 1.89 L/L/day when 23% VSmolasses was co-digested with cattle manure. However, digesters fed with more than 32% VSmolasses and with short adaptation period resulted in VFA accumulation and reduced methane productivity indicating that when using molasses as biogas booster this level should not be exceeded.

    The sugar contents in undiluted molasses were found to be stable on γ-irradiation. The contents of total sugar and direct reducing sugar in cane molasses were completely unaffected by irradiation with doses of less than 3 Mrad. The reduction of total sugar content in beet molasses was 2% at 3 Mrad. On the other hand, in the molasses diluted with water, sugar contents decreased with the dose. Sucrose in molasses was degraded by irradiation, and subsequently glucose and fructose were formed. Raffinose in beet molasses was also degraded by irradiation, but galactose could not be detected. The irradiation temperature ranging from room temperature to 61 0 C, was hardly responsible for the change of sugar contents, but the changes in sugar caused by irradiation were enhanced at pHs of less than 4 and with an excess of oxygen.

    On its continual round of CERN Member States, the European Committee for Future Accelerators (ECFA) met in Bern, Switzerland, in March. With CERN based in Geneva, and with a national research centre at the Paul Scherrer Institute (PSI), Villigen, Switzerland figures prominently in European particle physics. The Bern ECFA meeting provided a full picture of Swiss particle physics activities, project by project, and was prefaced by an overview by Claude Joseph of Lausanne. The number of experimental particle physicists in the country is about 200, with an academic staff of about 170. These are distributed among seven universities - Basel, Bern, Fribourg, Geneva, Lausanne, Neuchâtel and Zurich. In addition there are substantial research groups at ETH-Zurich and at PSI. Probably reflecting the proximity of CERN, the size of the national research community, when scaled to the population, is above the CERN Member State average. At CERN, there is a strong Swiss participation in research at the LEP electron-positron collider (concentrated on L3), with 44 physicists. There are also 33 physicists working at the LEAR low energy antiproton ring, in particular the Crystal Barrel and CP-LEAR studies. In addition there is interest in heavy ion research and in neutrino physics (NOMAD) as well as substantial participation in research and development work for experiments at the LHC. Away from CERN, there are 6 Swiss physicists working at the HERA electron-proton collider at DESY, Hamburg, with the national PSI programme involving about 40 physicists. (The PSI programme was covered at the Bern ECFA meeting by H.C. Walter.) Following the illustrious tradition of Fritz Zwicky, Switzerland also counts many astrophysicists. Theoretical physics, with a community of some 80 researchers, has a great tradition. Throughout the 20th century, leading Swiss research centres have been beacons of brilliance. Zurich, in particular, played a leading role, with Einstein, Schrödinger and Pauli among

    Swissmem, the Swiss association of mechanical and electrical engineering industries, founded a new photonics group in 2013. This reflects the importance of this key technology for Switzerland. Swissmem requested from the Swiss Universities of Applied Sciences to introduce a new bachelor program to fulfill the increasing demand of the Swiss industry of young academics in the field of photonics. Optech Consulting is investigating the Swiss photonics market since many years on behalf of Swissphotonics, the Swiss national thematic network for photonics. The study concluded that the total production volume of the Swiss photonics industry in the year 2013 was 3 billion Swiss francs and a slight growth is expected for 2014. The University of Applied Science HTW Chur is located in the Eastern part of Switzerland. This area of the Rhine valley is a technology cluster of innovative companies in the field of optics and electronics. The industry is growing and the R&D departments of the worldwide active companies are lacking well-educated photonics engineers. The HTW Chur is dedicated to establish the first Swiss bachelor in Photonics. Supported by strong industrial players and an excellent network, the HTW Chur developed different job descriptions and a complete curriculum, which reflect the needs of the Swiss photonics industry. Almost 60% of the ECTS of this national degree program are assigned to photonics specific courses and the practical projects are organized in close collaboration with the photonics industry. Curriculum, job descriptions and the industrial needs will be discussed in detail in this paper.

    Extraction of isoflavones from soy products remains a major challenge for researchers. Different extraction techniques have been employed but the need to use a cheap green extraction technique remains the main focus. This study applied fermentation of soy molasses using Saccharomyces cerevisiae for extraction of isoflavones and compared this technique to the conventional extraction method. The aluminum chloride colorimetric method was used for the determination of total flavonoid content of extracts. The highest yield was observed from extraction using ethyl acetate after fermentation of soy molasses and the lowest one was given by the extract from conventional extraction method. The DPPH radical scavenging activities of the extracts were also compared. The extract obtained using ethyl acetate after fermentation showed the highest antioxidant activity (0.0269 meq), while extract from conventional extraction had the lowest antioxidant activity (0.0055 meq). The effect of time on daidzein yield was studied using HPLC standard addition method. Daidzein concentration was higher in extract obtained at t = 80 min (3.82 ± 0.11 mg of daidzein /g of extract) as compared to that obtained at t = 60 min (2.89 ± 0.10 mg of daidzein /g of extract).

    The effects of adding two legumes, Gliricidia sepium and Leucaena leucocephala, cv. Cunningham, and molasses on the fermentation characteristics of silages made from two tropical grasses (Pangola grass, Digitaria decumbens, and Setaria sphacelata cv. Kazungula) were investigated. Pangola grass silages contained significantly higher contents of water-soluble carbohydrates and lactic acid than did setaria silages after 100 days fermentation, but there were no significant differences between the two silages in populations of lactic acid bacteria and contents of total N and NH3-N. Addition of either species of legume had no significant effect on fermentation acids and NH3-N contents, and numbers of lactic acid bacteria. Addition of both legumes reduced NH3-N production in the silages by 59% after 5 days' fermentation. Numbers of lactic acid bacteria were not significantly affected by the different treatments. Enterococcus faecalis represented 60% of the lactic acid bacteria isolated from the treated herbages prior to ensiling. By 100 days of fermentation, only lactobacilli were isolated: 82% homo-fermenters and 18% hetero-fermenters. Lactobacillus mesenteroides subsp. dextranicum was found only in the silage supplemented with 33% (w/w) legume. It was concluded that the low quality of tropical grasses used as feeds for ruminants may be significantly improved by ensiling these grasses with small amounts of molasses and with high-protein tree leaves.

The maximum specific growth rate (µmax), lipid productivity (Pr) and cellular lipid content were, respectively, 0.23 h(-1), 0.41 g l(-1) h(-1), and 41% for Rsp. toruloides; 0.20 h(-1), 0.27 g l(-1) h(-1), and 36% for Rta. glutinis; 0.115 h(-1), 0.135 g l(-1) h(-1), and 27 % for Rta. minuta; and 0.11 h(-1), 0.13 g l(-1) h(-1), and 32% for L. starkeyi. Based on their microbial lipid productivity, content, and profile, Rsp. toruloides and Rta. glutinis are promising candidates for biodiesel production from Brazilian molasses. All the oils from the yeasts were similar to the composition of plant oils (rapeseed and soybean) and could be used as raw material for biofuels, as well as in food and nutraceutical products.

    Full Text Available A study was conducted in Balai Penelitian Temak Bogor to evaluate the effect of urea-molasses treatment on the quality of rice straw . Five levels of urea were 0%, 0.5%, 1%, 1 .5% and 2% and 4 levels of molasses were 0%, I%, 2% and 3%. The study was conducted based on factorial completely randomized design with 3 replications . Urea and molasses were mixed with 5 kg chopped rice straw and stored for 21 days in plastic bag . Parameters observed were dry matter, organic matter, crude protein, crude fibre, and silica contents . Nutritive value of rice straw was measured by proximate analysis and its nutrient digestibility by in-vitro using rumen liquid of fistulated Ongole-crossed cattle . The results showed that urea and molasses treatment on rice straw decreased the dry matter and silica contents but increased the crude protein content of rice straw (P<0 .01. Dry matter and organic matter digestibility of rice straw didn't show the significant different among urea treatment but highly significant increased (P<0.01 by the molasses treatment. It was concluded that urea and molasses treatment on rice straw could improve the quality so that by the levels of 1 .5% urea and 3% molasses produced the similar quality with napier grass .

  2. Molasses as a possible cause of an ''endocrine disruptive syndrome'' in calves

    Full Text Available During the mid 1990s a potentially serious, chronic syndrome was reported in well-managed beef and dairy herds from unrelated parts of South Africa. Farmers reported that it manifested as various combinations of decreased production, decreased weaning masses, apparent immune breakdown in previously immunocompetent animals, increased reproductive disorders, various mineral imbalances in non-deficient areas and goitre, noticeable as enlarged thyroid glands. The farmers associated this syndrome with certain batches of sugar cane molasses and molasses-based products. The syndrome was reminiscent of an ''endocrine disruptive syndrome''. The objective of this study was to evaluate the suspected endocrine disruptive effect of molasses included in cattle feed. Using existing in vitro assays, four batches of molasses syrup were screened for possible inclusion in a calf feeding trial. Two batches were selected for the trial. Thirty-two, 4- to 6-week-old, weaned Holstein bull calves were included in the single phase, three treatment, parallel design experiment. In two of the groups of calves, two different batches of molasses were included in their rations respectively. The control group was fed a ration to which no molasses was added, but which was balanced for energy and mineral content. The mass gain of the calves was recorded over the 6-month study period. The calves were clinically examined every week and clinical pathology parameters, immune responses and endocrine effects were regularly evaluated. Even though endocrine disrupting effects were detected with the in vitro screening assays, these could not be reproduced in the calves in the experiment. The two batches of molasses utilized in the calf feeding trial did not induce major differences in any of the parameters measured, with the exception of a lower mass gain in one of the molasses-fed groups (Group 1, which tended towards significance. The results of the study indicate that the two batches

    Full Text Available Objective(s: Sugar cane molasses is a commonly used ingredient in several food products. Contrasting reports suggest that molasses may have potential adverse or beneficial effects on human health. However, little evidence exists that examines the effects of molasses on the different physiological systems. This study investigated the effects of sugar cane molasses on various physiological systems using in vivo and in vitro methods. Materials and Methods: Molasses was administered orally to BALB/c, male mice and animals were randomly assigned into either a treatment or control group. General physiological changes, body weight and molasses intake of animals were monitored. At the end of the exposure period, collected blood samples were evaluated for potential toxicity using plasma biomarkers and liver enzyme activity. Immunised treated and untreated mice were evaluated for antibody titre to determine the effect of molasses on the immune response. To investigate the impact of molasses on testicular steroidogenesis, testes from both treated and control groups were harvested, cultured and assayed for testosterone synthesis.  Results: Findings suggest that fluid intake by molasses-treated animals was significantly increased and these animals showed symptoms of loose faeces. Molasses had no significant effect on body weight, serum biomarkers or liver enzyme activity (P>0.05.  Immunoglobulin-gamma anti-antigen levels were significantly suppressed in molasses-treated groups (P=0.004. Animals subjected to molasses exposure also exhibited elevated levels of testosterone synthesis (P=0.001. Conclusion: Findings suggests that molasses adversely affects the humoral immune response. The results also promote the use of molasses as a supplement to increase testosterone levels.

    Information on structure and mechanics of fault systems and their connection with present-day seismicity is key to the understanding of neotectonic processes in the Swiss Alps and the northern Swiss Foreland. Precisely determined focal depths in combination with high-resolution structural models can provide important insight into deformation styles of the uppermost crust (e.g. thin- vs. versus thick-skinned tectonics). Detailed images of seismogenic fault zones combined with estimates on deformation rates from geodesy, on the other hand, will improve the assessment of the hazard related to natural and induced earthquakes in those regions. In the framework of various projects, studies have been recently undertaken to image seismogenic fault zones at high resolution, with a special focus on southwest and northeast Switzerland because of their high societal relevance. Southwest Switzerland, is the region with one of the highest natural seismic hazard in the country. A large part of the present-day seismic activity is related to an earthquake lineament located in the southern part of the Rawil depression, which is dominated by strike-slip faulting. The possibility of large magnitude earthquakes critically depends on the question as to whether this activity is related to a single fault of considerable lateral and vertical extension or not. Field data demonstrate oblique normal faulting and fault segmentation at surface related to mountain uplift at the curvature of the Alpine Arc. Studies of seismogenic structures and neotectonic processes in the northeast Molasse basin, on the other hand, are of special interest, since the region is one of the target sites for radioactive waste repositories and future geothermal plants. On-going densification of the seismic network in Switzerland and new detection algorithms have significantly lowered the detection threshold of microearthquakes and improved data coverage in most parts of the country over the last ten years.

    The effects of supplementation with urea molasses mineral blocks and molasses-urea mix during and immediately prior to the dry season on the production of dairy cows were studied on-station and on small holder peri-urban farms near Morogoro, Tanzania. Supplementation of on-station cows receiving ad libitum grass hay and 6 kg/d of maize bran with urea molasses mineral blocks (UMMB), increased milk production from 6.7 L/d to 11.2 L/d (P <0.05) and dry matter intake from 10.1 kg/d to 12.0 kg/d (P <0.05), but did not significantly affect milk composition, intake of hay and live weight change. This increase in milk yield is mainly explained by increased intakes of energy and nitrogen. Supplementation with the molasses urea mix increased daily milk yield from 6.7 L/d to 8.8 L/d (P <0.05), but did not significantly affect the other measured production parameters. The on-farm supplementation with blocks increased daily milk yield by 1.7 L/d in the dry season (P <0.01). This supplementation did not increase milk yields prior to the dry season, since quality forage was still available. Taking the production costs into account, supplementation with the blocks and supplementation with molasses mix was cost effective if milk yields increased by 0.7 L/d. (author)

    Molasses, the main byproduct of sugar production, is a well-known source of antioxidants. In this study sugar cane molasses (SCM) and sugar beet molasses (SBM) were investigated for their phenolic profile and in vitro antioxidant capacity and for their protective effect in human HepG2 cells submitted to oxidative stress. According to its higher phenolic concentration and antioxidant capacity in vitro, SCM exhibited an effective protection in cells, comparable to or even greater than that of α-tocopherol. Data herein reported emphasize the potential health effects of molasses and the possibility of using byproducts for their antioxidant activity. This is particularly important for consumers in developing countries, as it highlights the importance of consuming a low-price, yet very nutritious, commodity.

  11. Production of Microbial Transglutaminase on Media Made from Sugar Cane Molasses and Glycerol

    2009-01-01

    Full Text Available Transglutaminase is an enzyme that catalyses an acyl transfer reaction between γ-carboxamide groups of glutaminyl residues and lysine residues in proteins. Due to this property, this enzyme is used for enhancing textural properties of protein-rich food. The transglutaminase used as food additive is obtained by microorganisms, mainly by Streptoverticillium ladakanum. On the other hand, sugar cane molasses is a viscous liquid rich in noncrystallized carbohydrates (saccharose, glucose and fructose. In this work, the feasibility of using sugar cane molasses as a carbon source for the production of microbial transglutaminase by Streptoverticillium ladakanum NRRL 3191 has been studied. Carbon sources including sugar cane molasses (60 g of total sugars per L, glycerol (60 g/L and their mixture in a ratio of 1:1 (30 g/L of each were evaluated. Time course of microbial growth, transglutaminase activity and carbon source consumption were determined every 24 h during 120 h of fermentations at three agitation speeds (200, 300 or 400 rpm. The results showed that with the increase in agitation speed, the biomass concentration increased up to 8.39 g/L in the medium containing sugar cane molasses alone or the mixture of molasses and glycerol. The highest transglutaminase activity was obtained at 400 rpm in the medium containing a mixture of molasses and glycerol, reaching 0.460 U/mL, while in the medium containing sugar cane molasses alone, the activity was 0.240 U/mL, and using glycerol alone it was 0.250 U/mL. These results show that sugar cane molasses is a suitable medium for transglutaminase production when it is combined with glycerol.

    Acetic acid is considered an important preservative in tropical grass ensiling. The objective of the current experiments was to follow the ensiling fermentation of low dry matter (DM) tropical grass as a model to study changes in bacterial communities during acetic acid fermentation. Direct-cut and wilted guinea grass silage was prepared with and without molasses. A high acetic acid level was observed during the fermentation of direct-cut silage, and long storage increased the butyric acid and ethanol content if molasses was not added. The lactic acid production in wilted silage was greater than the acetic acid production, but prolonged ensiling decreased the lactic to acetic acid ratio regardless of molasses addition. Adding molasses enhanced the lactic acid content in both direct-cut and wilted silage. The bacterial community, identified by denaturing gradient gel electrophoresis, was affected by wilting and molasses addition. Bands for Pantoea sp. and Morganella sp. became faint when acetic acid fermentation was suppressed, and those for Pediococcus pentosaceus and Lactococcus garvieae were detected when lactic acid fermentation was enhanced by wilting and molasses addition. Lactobacillus plantarum and Lactococcus lactis were found throughout the ensiling process in all silage types. Distinct changes occurred in the bacterial community in guinea grass silage because of wilting and molasses addition. These changes could explain how lactic acid fermentation was enhanced but could not help determine which bacteria were associated with enhanced acetic acid fermentation. The study reveals the effects of wilting and molasses during ensiling of low DM tropical grasses and the associated bacteria. © 2011 The Authors.

    Sugarcane molasses is a potential by-product of the sugarcane manufacturing industry that is rich in antioxidant materials. The present study aimed to obtain antioxidative compounds from sugarcane molasses and to evaluate their ability to protect DNA from oxidative damage. Two neolignan glucosides were isolated from sugarcane molasses using bioassay and UV spectra monitoring-guided fractionation. The compounds were elucidated as (7R,8S)-dehydrodiconiferyl alcohol-4-O-β-d-glucoside (1) and (7S,8R)-simulanol-9'-O-β-d-glucoside (2). Neolignan glucoside 2 protected against DNA damage caused by free radicals more effectively than did neolignan glucoside 1 (13.62 and 9.08 µmol L(-1) for peroxyl and hydroxyl radicals, respectively, compared to 48.07 and 14.42 µmol L(-1) ). Additionally, neolignan glucoside 2 exhibited superior DNA protection against free radicals compared with various known antioxidative compounds, including p-coumaric acid, ferulic acid, vanillic acid and epigallocatechin gallate. The isolated neolignan glucosides from sugarcane molasses are able to protect DNA from oxidative damage caused by free radicals. This is the first identification of these two compounds in sugarcane molasses. The sugarcane molasses can therefore be used as potential nutraceutical preventative agents, and the findings may foster the utilization of this by-product as a bioresource-based product. © 2015 Society of Chemical Industry.

    Full Text Available ABSTRACT: Ensilage is a simple and low-cost strategy to enable long term preservation and environmentally friendly utilization of agricultural by-products, such as straws and distiller's grains (DG for ruminants. Effect of mixing different proportions of DG and rice straw (i.e. 0, 10, 20 or 30% of DG with or without 5% molasses addition on fermentation and chemical variables of silages was evaluated. The study was conducted as a randomized blocks design in a 4 × 2 factorial arrangement, with three replications, using laboratory silos of 1L capacity (n=24. Despite a significant interaction (P<0.01 between DG and molasses addition was observed for most variables, in general the increased addition of DG linearly decreased the pH value, acetic acid (AA, butyric acid (BA and ammonia N concentration (P<0.01, and increased the lactic acid (LA concentration (P<0.01. Exception was the propionic acid concentration which linearly decreased without molasses addition and linearly increased with molasses addition at increased proportion of DG (P<0.01. In both silages with or without molasses the addition of DG increased the dry matter, water soluble carbohydrates and crude protein (P<0.01, and decreased the NDF content (P<0.01. Based on the perspective of maximum utilization of rice straw, the mixture of 10% of DG associated to 5% molasses at ensilage process is recommended.

    Using anaerobic micro-organisms to convert organic waste to produce hydrogen gas gives the benefits of energy recovery and environmental protection. The objective of this study was to develop a biohydrogen production technology from food wastewater focusing on hydrogen production efficiency and micro-flora community at different hydraulic retention times. Soluble condensed molasses fermentation (CMS) was used as the substrate because it is sacchariferous and ideal for hydrogen production. CMS contains nutrient components that are necessary for bacterial growth: microbial protein, amino acids, organic acids, vitamins and coenzymes. The seed sludge was obtained from the waste activated sludge from a municipal sewage treatment plant in Central Taiwan. This seed sludge was rich in Clostridium sp. A CSTR (continuously stirred tank reactor) lab-scale hydrogen fermentor (working volume, 4.0 L) was operated at a hydraulic retention time (HRT) of 3-24 h with an influent CMS concentration of 40 g COD/L. The results showed that the peak hydrogen production rate of 390 mmol H{sub 2}/L-d occurred at an organic loading rate (OLR) of 320 g COD/L-d at a HRT of 3 h. The peak hydrogen yield was obtained at an OLR of 80 g COD/L-d at a HRT of 12 h. At HRT 8 h, all hydrogenase mRNA detected were from Clostridium acetobutylicum-like and Clostridium pasteurianum-like hydrogen-producing bacteria by RT-PCR analysis. RNA based hydrogenase gene and 16S rRNA gene analysis suggests that Clostridium exists in the fermentative hydrogen-producing system and might be the dominant hydrogen-producing bacteria at tested HRTs (except 3 h). The hydrogen production feedstock from CMS is lower than that of sucrose and starch because CMS is a waste and has zero cost, requiring no added nutrients. Therefore, producing hydrogen from food wastewater is a more commercially feasible bioprocess. (author)

    The yeast Zygosaccharomyces mellis and the mould Wallemia sebi were isolated from the same sample of crystalline sugar. Interactions between these fungi were investigated using a diluted molasses medium (water activity 0.89, pH 6.0) as a model system for the syrup film covering the surface of moist crystalline sugar. Single and mixed cultures of Z. mellis and W. sebi were incubated at 25 degrees C for 400 h. Our results show that the growth of Z. mellis in single culture was limited by available glucose and fructose, and that W sebi was able to invert sucrose to glucose and fructose in both single and mixed culture. Furthermore, the presence of W. sebi in the mixed culture increased the maximum specific growth rate of Z. mellis from 0.074 to 0.19 h(-1) and the growth yield of Z. mellis from 7.3 x 10(6) to 5.4 x 10(7) cfu/ml. These results indicate that the ability of W. sebi to invert sucrose may stimulate the growth of Z. mellis. Finally, the presence of Z. mellis inhibited the ability of W. sebi to invert sucrose: W. sebi was able to invert 1.0 g sucrose/l per h in single culture but only 0.6 g sucrose/l per h in mixed culture. As predicted by Raoults law, this corresponded to a reduction in the water activity of the growth medium from 0.890 to 0.850 in single culture, and to 0.865 in mixed culture.

  4. 3D structural model of the North Alpine Foreland Basin, Bavarian Part

    The continental collision of Europe and Africa leads to the rise of the European Alps, which gave way to the formation of the North Alpine Foreland Basin, also referred to as the Molasse Basin, since the Tertiary. This typically wedge formed "foredeep" basin is filled with predominantly clastic sediments originating from erosional processes of the Alps which overly a southward dipping Mesozoic and Paleozoic succession. With our project we want to contribute to the understanding of the structure and subsequently of the thermal configuration of the Molasse Basin and its underlying deposits on a basin wide scale. We constructed a 3D structural model of the basin down to the crust-mantle-boundary, beginning with the Bavarian part. Therefore we used an approach of already existing local to midscale 2D and 3D structural models (e.g. Lüschen et al. 2006) as well as surface maps, seismic, well and gravity data. This 3D structural model resolves 5 sedimentary layers of the Mesozoic, including the geothermally utilized carbonate Malm aquifer (e.g. Birner et al. 2011), as well as the combined Paleozoic basement. Assuming isostatic equilibrium of the system a lithosphere-asthenosphere-boundary (LAB) has been calculated and compared to other published LABs of the region. Subsequently the model has been further constrained by 3D gravity modeling. The outcomes show that Cretaceous sediments are restricted to a small region in the central to eastern model area and are mostly overlain by the Tertiary Molasse sediments. The Triassic sediments occur in the northern and western part of the model area and do not continue far under the Molasse basin proper, while the Jurassic can be tracked as far south as beneath the Alps. The evaluation of the gravity indicates that the crystalline crust consists of a lighter upper crust and a denser lower crust. Our final LAB is shallowest under the Triassic subbasin, descending below the Bohemian Massif and the Molasse Basin proper and rising again

    2012-11-01

    A field study was carried out to monitor the effect of application of molasses based distillery effluent on yields of sugarcane and soil properties. The treatments consisted of main plots: control (I0), first pre-sowing irrigation with undiluted effluent (I1), one irrigation with effluent: tube-well water (1:3) at tillering stage (I2), two irrigations with effluent: tube-well water (1:4) at tillering and 30 d after tillering stage (I3). The subplots either received no fertilizer application (F0) or had 50 % of recommended dose (50 kg N, 60 kg P(2)O(5) and 40 kg K(2)O ha(-1) as basal dose (F1) with top dressing of 50 kg N ha(-1) at tillering and in June before the onset of monsoon. Nitrogen to the ratoon crops was applied in three equal splits. Application of 50 % recommended fertilizer dose increased the cumulative cane yields under different effluent treatments. Use of distillery effluent irrespective of the method of application significantly increased the cumulative yields of sugarcane over no application of effluent significantly at p ≤ 0.05. After the harvest of second ratoon crop, no significant effect of different treatments was noted on soil pH, electrical conductance and exchangeable Na. Significantly higher build-up of organic C in surface soil was noted under I2 treatment in comparison to I0 treatment at p ≤ 0.05. With no fertilizer application, both I1 and I2 significantly increased accumulation of alkaline KMnO(4) hydrolysable N in 30-45 cm layer in comparison to I0F0 at p ≤ 0.05. In comparison to I0, use of I2 increased the content of Olsen's P significantly (p ≤ 0.05) in 30-45 and 45-60 cm layers while I3 increased it significantly at p ≤ 0.05 in 0-15 and 45-60 cm layers. Use of distillery effluent as pre-sowing or standing crop irrigation increased ammonium acetate extractable K in surface and sub-surface layers significantly in comparison to I0 at p ≤ 0.05. Thus, use of distillery effluent in sugarcane crop as pre-sown or standing crop

    2015-04-01

    Response surface methodology was used to optimise experimental conditions for ultrasonic-assisted extraction (UAE) of functional components from sugar beet molasses. The central composite design (CCD) was used for the optimisation of extraction parameters in terms of total phenolic contents, antioxidant activities and anthocyanins. Result suggested the optimal conditions obtained by RSM for UAE from sugar beet molasses were as follows: HCl concentration 1.55-1.72 mol/L, ethanol concentration 57-63% (v/v), extraction temperature 41-48 °C, and extraction time 66-73 min. In the optimal conditions, the experimental total phenolic contents were 17.36 mg GAE/100mL, antioxidant activity was 16.66 mg TE/g, and total anthocyanins were 31.81 mg/100g of the sugar beet molasses extract, which were well matched the predicted values. Teen compounds, i.e. gallic acid, vanillin, hydroxybenzoic acid, syringic acid, cyanidin-3-O-rutinoside, cyanidin-3-O-glucoside, catechin, delphinidin-3-O-rutinoside, delphinidin-3-O-glucuronide and ferulic acid were determined by HPLC-DAD-MS/MS in sugar beet molasses.

    Acid catalysts were prepared by sulfonation of carbon materials obtained from the pyrolysis of sugar beet molasses, a cheap, viscous byproduct in the processing of sugar beets into sugar. Conditions for the pyrolysis of molasses (temperature and time) influenced catalyst performance; the best combination came from pyrolysis at low temperature (420 °C) for a relatively long time (8-15 h), which ensured better stability of the final material. The most effective molasses catalyst was highly active in the esterification of fatty acids with methanol (100 % yield after 3 h) and more active than common solid acidic catalysts in the transesterification of vegetable oils with 25-75 wt % of acid content (55-96 % yield after 8 h). A tandem process using a solid acid molasses catalyst and potassium hydroxide in methanol was developed to de-acidificate and transesterificate algal oils from Chlamydomonas reinhardtii, Nannochloropsis gaditana, and Phaeodactylum tricornutum, which contain high amounts of free fatty acids. The amount of catalyst required for the de-acidification step was influenced by the chemical composition of the algal oil, thus operational conditions were determined not only in relation to free fatty acids content in the oil, but according to the composition of the lipid extract of each algal species.

  3. Ensilage characteristics of three tropical grasses as influenced by stage of growth and addition of molasses.

    Tjandraatmadja, M; Norton, B W; Mac Rae, I C

    1994-01-01

    When molasses was added during ensilage of three tropical grasses [hamil grass (Panicum maximum cv. Hamil), pangola grass (Digitaria decumbens) and setaria (Setaria sphacelata cv. Kazungula)] the final pH, concentration of fermentation acids (except lactic acid) and NH3-N content were all similar after 100 days of incubation. Pangola grass silage had significantly higher lactic acid content (66 g/kg dry matter) than the other two. Adding either 4 or 8% (w/w) molasses reduced NH3-N, volatile fatty acid content and pH but increased lactic acid content in the final silages. Numbers of lactic acid bacteria remained approximately constant during the course of the fermentation, although large differences were noted in the species composition of the populations. At the time of ensiling, only Pediococcus spp. and Leuconostoc spp. were detected. By 5 days, the homo-fermentative population, notably Lactobacillus plantarum, dominated (43%) and remained dominant. Hetero-fermentative rods were only detected in the 100-day silage, where they represented 29% of the strains isolated. Homo-fermenters were more abundant in pangola (60%) and setaria (47%) silages than hamil (27%) silages. Homo-fermenter populations were lowest in the 12-week forage. Molasses additions increased homo-fermenter populations. Pangola grass gave the best quality silage but, since the water-soluble carbohydrate content in the grasses was insufficient to promote a strong lactic fermentation, the addition of 20 to 30 kg molasses/tonne should achieve satisfactory preservation.

    Molasses are a potential feedstock for ethanol production. The successful application of anaerobic fermentation for ethanol production from molasses is critically dependent to the development and the use of high rate bioreactors. In this study the fermentation of sugar cane molasses by Saccharomyces cerevisiae for the ethanol production in a continuously stirred tank reactor (CSTR), an immobilised cell reactor (ICR) and a membrane reactor (MBR) was investigated. Ethanol production and reactor productivities were compared under different dilution rates (D). When using the CSTR, a decent ethanol productivity (Qp) of 6.8 g L −1 h −1 was obtained at a dilution rate of 0.5 h −1 . The Qp was improved by 48% and the residual sugar concentration was reduced by using the ICR. Intensifying the production of ethanol was investigated in the MBR to achieve a maximum ethanol concentration and a Qp of 46.5 g L −1 and 19.2 g L −1 h −1 , respectively. The achieved results in the MBR worked with high substrate concentration are promising for the scale up operation. -- Highlights: ► We compare three reactors for ethanol production from sugar cane molasses. ► The ethanol productivity of 6.8 g L -1 h -1 was obtained using the CSTR. ► The ethanol productivity was improved by 48% by using the ICR. ► Intensifying ethanol productivity (19.2 g L -1 h -1 ) was investigated in the MBR

    Full Text Available This work objective is to find the technological conditions for the intensification of yeast growth in the gradient-continuous yeast cultivation process. Experiments on four sequential yeast chemostats (connected into a battery demonstrated broad possibilities to influence the metabolic activity of yeast and the alcohol production depending on the content of molasses introduced into the second, third and fourth yeast generators. Adding the molasses according to the 3:2:1 scheme in quantities, which are sufficient to achieve the initial concentration of solids of 26.5 g/100 cm3 to the end of the process resulted in high accumulation of yeast in the medium (up to 99 g/dm3. It is demonstrated that the highest ratio of economic effect of biomass synthesis from molasses sugars (88 g/100 g is achieved when molasses is added according to the 1:2:2.5 scheme and the initial solids concentration in the medium is near 12 g/100 cm3.

    Sugarcane bagasse (SCB) and molasses, known as carbohydrate-rich biomass derived from sugar production, can serve as feedstock for bio-ethanol production. To establish a simple process, the production of bio-ethanol through integration of whole pretreated slurry (WPS) of SCB with molasses was investigated. The results showed that microwave-assisted dilute sulfuric acid pretreatment reduced the formation of toxic compounds compared to a pretreatment process involving "conventional heating". Pretreatment at 180 o C with 10% w v -1 solid loading and 0.5% w v -1 H 2 SO 4 was sufficient to achieve efficient enzymatic saccharification of WPS. By conducting separate hydrolysis and fermentation (SHF), an ethanol yield of 90.12% was obtained from the mixture of WPS and molasses, but the ethanol concentration of 33.48 g L -1 was relatively low. By adopting fed-batch SHF, the ethanol concentration reached 41.49 g L -1 . Assuming that the molasses were converted to ethanol at an efficiency of 87.21% (i.e., ethanol was obtained from fermentation of molasses alone), the ethanol yield from WPS when a mixture of WPS and molasses was fermented was 78.30%, which was higher than that of enzymatic saccharification of WPS (73.53%). These findings suggest that the production of bio-ethanol via integration of WPS with molasses is a superior method. Graphical Abstract ᅟ.

    Full Text Available The purpose of the research was to establish Acinetobacter sp. IMB B-7005 cultivation conditions, which provide the maximal synthesis of microbial exopolysaccharide ethapolan on a mixture of molasses and sunflower oil, and to explore the possibility of replacing refined oil in a mixture with molasses for waste one. On the basis of theoretical calculations of energy consumption for the synthesis of ethapolan and biomass, it was determined that the optimal molar ratio of the concentrations of energy-deficient (sucrose and energy-excessive (sunflower oil substrates in the mixture was 1.0:0.9. Experiments have shown that the highest values of exopolysaccharide synthesis were observed at a molar ratio of monosubstrates in mixture 1.0:1.1, which is as close as possible to the theoretically calculated one. It was shown that increasing concentration of molasses and refined oil in mixture from 1.0 to 1.5% was accompanied by increase in amount of synthesized exopolysaccharide and its synthesizing capacity by 1.2 and 1.3 times, respectively. The possibility of replacing refined oil in a mixture with molasses for various types of waste (after frying potatoes, meat, vegetables and mixed was established. The maximum parameters of exopolysaccharide synthesis (concentration 14 g/l, synthesizing capacity 3.5 g exopolysaccharide/g biomass were observed when using mixed waste oil for both inoculum obtaining and EPS biosynthesis. The obtained results testify to the possibility of development of universal technology for obtaining microbal exopolysaccharide ethapolan on a mixture of waste (molasses and waste oil independent of the type and provider of waste oil.

    Studies conducted since the 1960s on the sedimentary formations of the Béli region have not permitted the establishment of a lithostratigraphic log for the area. Based on fieldwork involving drafting of cross-sections and lithologic, petrographic and structural studies, a triad and a molasse formation have been described for the first time in this portion of the basin. Therefore, as in the sedimentary formations of the Taoudeni and Volta Basins, the formations in the Béli area, located on the southern edge of the Gourma Basin (northeastern Burkina Faso), include an association of ;Tillite-limestone-chert; that is correlated with the ;triad; of the Taoudeni Basin. The lithostratigraphic section of the Béli area comprises eight formations. The triad overlays quartzitic sandstones and is covered by shales and dolomite. Above the triad is the metamorphic allochthonous unit composed of phyllites, which are covered by the molassic formation. As in the carbonate formations, some rocks of the cherty complex contain stromatolites as well as micro-organisms. The Pan-African deformation is characterized by folding, schistosity and a fault network. Compressive phases D1, D3 and D4 of the Pan-African orogeny are identified, and we suspect a reactivation of Pan-African fractures during the Cenozoic. The characteristics of the tectonic episodes are utilized to distinguish two structural units: the allochthonous unit of North Béli, characterized by a ductile deformation and an anchi-metamorphism thrust on the para-autochthonous unit of South Béli. The latter is marked by a dominant brittle deformation; it underwent non-metamorphism and is thrust on the Eburnean basement. The cherty formation of the triad contains a polymetalliferous mineralization that was probably enriched during the different tectonic events.

    Full Text Available This study examined the effects of urea and molasses on fermentation dynamics and structural carbohydrate degradation of Napiergrass (Pennisetum purpureum Schumach, which was ensiled in laboratory silos for 3, 7, 14, and 30 days at the ambient temperature. The treatments were additions (fresh weight basis of: no molasses or urea (control, no molasses and 0.4% urea (U, 4% molasses and 0% urea (M, 4% molasses and 0.4% urea (MU. The results showed that the control group produced an unstable fermentation. U silage always had smallest amount of lactic acid and highest levels of pH, acetic acid, butyric acid and ammonia nitrogen. Compared with control, both M and MU increased water soluble carbohydrate contents which promoted lactic acid fermentation domination, but MU did not restrain clostridial fermentation. After 30 days of ensiling, compared with the control, both M and MU lowered structural carbohydrate contents, and U lowered crude protein content but MU increased this parameter. It was concluded that the combination of 4% molasses with 0.4% urea could improve the fermentation and nutritive qualities of Napiergrass but was not sufficient to inhibit clostridial fermentation.

    Lactic acid is an important chemical with various industrial applications, and it can be efficiently produced by fermentation, in which Bacillus coagulans strains present excellent performance. Betaine can promote lactic acid fermentation as an effective osmoprotectant. Here, positive effect of betaine on fermentation by B. coagulans is revealed. Betaine could enhance lactic acid production by protecting l-LDH activity and cell growth from osmotic inhibition, especially under high glucose concentrations and with poor organic nitrogen nutrients. The fermentation with 0.05 g/L betaine could produce 17.9% more lactic acid compared to the fermentation without betaine. Beet molasses, which is rich in sucrose and betaine, was utilized in a co-feeding fermentation and raised the productivity by 22%. The efficient lactic acid fermentation by B. coagulans is thus developed by using betaine and beet molasses.

  1. Kinetic study of sulfite ion inhibition during alcoholic fermentation of beet molasses

    Energy Technology Data Exchange (ETDEWEB)

    Glacet, A.; Letourneau, F.; Leveque, P.; Villa, P. (UER des Sciences Exactes et Naturelles, 80 - Amiens (France))

    Alcoholic fermentation cycle has been studied on beet molasses exempt from sulfite ions, and containing added amounts of these ions from 1000 to 3000 ppm. Experimental results show that fermentation duration increasing sulfite concentration in the medium from 8% to 40% if SO/sub 3//sup - -/ added varies from 1000 to 3000 ppm. A detailed kinetic study reveals that this increase occurs only during latency period. Moreover the biomass and the ethanol generation curves drawn after latency period appear to be quite linear, their slopes being independent of initial sulfite concentration. Sulfite evolution during fermentation cycle of artificial wort, under identical experimental conditions to those of wort molasses, indicates that more than 80% of these ions disappear during latency period. We have proved that this phenomenon is due to yeast action and not to any chemical reactions between sulfites ions and wort components.

    A molasses based medium for the biosurfactant production by Pseudomonas fluorescens was developed, where the effect of pre-treated of molasses and medium composition were evaluated. Biosurfactant production was followed by measuring optical density (OD), surface tension and emulsifying index (E24) over 12 days of fermentation. The optimum condition for the biosurfactant production was obtained when a medium containing of 8 g/L nutrient broth, 5 g/L NaCl, 1 g/L NH4NO3 and 5% v/v pre-treated molasses with centrifugation was used as media with 3 days of fermentation. The biosurfactant was identified as a rhamnolipid type biosurfactant which had critical micelle concentration (CMC) value of 801 mg/L and was able to reduce the surface tension of the water from 80 mN/m to 51 mN/m. The biosurfactants had water in oil (w/o) emulsion type. Biosurfactant was able to emulsify various hydrocarbons, which were able to decrase the interfacial tension about 50-75% when benzyl chloride, anisaldehyde and palm oil were used as immiscible compounds. The biosurfactant exhibited the E24 value of about 50% and the stable emulsion was reached up to 30 days when lubricant was used as an immiscible compound. Up to 68% of phenol was degraded in the presence of biosurfactant within 15 days, whereas only 56% of phenol was degraded in the absence of biosurfactant. Overall, the results exhibited that molasses are recommended for the rhamnolipids production which possessed good surface-active properties and had potential application in the enhancement of phenol degradation.

    The fermentation of molasses wort is enhanced by using a large inoculum of yeast (approx.60 g/L). Addition of H3PO4 promotes active multiplication of yeast and results in the accumulation of the highest EtOH content (9.24%). Addition of both P and N (urea) to the fermentation medium results in the production of less alcohol (9.17%). The alcohol yield in the absence of both elements was 9.10%.

    In recent years, bioethanol from sugarcane molasses has been produced on an industrial scale in Iran. The aim of this study was to evaluate molasses-based bioethanol production from an environmental point of view. Data were collected from Debel Khazai agro-industry situated in southern region of Iran by using face-to-face interviews and annual statistics of 2010 to 2016 (6-year life cycle of sugarcane cultivation). Ten impact categories including abiotic depletion (AD), acidification (AC), eutrophication (EP), global warming potential (GWP), ozone layer depletion (OLD), human toxicity (HT), freshwater aquatic ecotoxicity (FE), marine aquatic ecotoxicity (ME), terrestrial ecotoxicity (TE), and photochemical oxidation (PO) were selected based on CML methodology. Inventory data for production of the inputs were taken from Ecoinvent, BUWAL 250, and IDMAT 2001 databases. The results revealed that in sugarcane cultivation process, electricity and trash burning were the most important contributors to all impact categories except OLD and TE. In industrial phase, natural gas had the highest contribution to the most impact categories. Greenhouse gas (GHG) emission for production of 1000 L molasses-based bioethanol was 1322.78 kg CO 2  eq. By comparing total GHG emissions from 1000 L bioethanol to gasoline, the net avoided GHG emissions came out at 503.17 kg CO 2  eq. According to results, it is clear that with increasing irrigation efficiency and improving performance of heating systems in industrial phase, environmental burdens would be significantly reduced.

    Full Text Available This study aimed the optimization of culture condition and composition for production of Cryptococcus laurentii 11 biomass and lipids in cheese whey medium supplemented with sugarcane molasses. The optimization of pH, fermentation time, and molasses concentration according to a full factorial statistical experimental design was followed by a Plackett-Burman experimental design, which was used to determine whether the supplementation of the culture medium by yeast extract and inorganic salts could provide a further enhancement of lipids production. The following conditions and composition of the culture medium were found to optimize biomass and lipids production: 360 h fermentation, 6.5 pH and supplementation of (g L-1: 50 molasses, 0.5 yeast extract, 4 KH2PO4, 1 Na2HPO4, 0.75 MgSO4•7H2O and 0.002 ZnSO4•H2O. Additional supplementation with inorganic salts and yeast extract was essential to optimize the production, in terms of product concentration and productivity, of neutral lipids by C. laurentii 11. Under this optimized condition, the production of total lipids increased by 133% in relation to control experiment (from 1.27 to 2.96 g L-1. The total lipids indicated a predominant (86% presence of neutral lipids with high content of 16- and 18- carbon-chain saturated and monosaturated fatty acids. This class of lipids is considered especially suitable for the production of biodiesel.

    Bacterial cellulose (BC) has unique properties such as structural, functional, physical and chemical. The mass production of BC for industrial application has recently become attractive to produce more economical and high productive cellulose. In this study, to improve the productivity of bacterial cellulose (BC), BC production by Gluconacetobacter xylinus FC01 was investigated in molasses medium with static semi-continuous operation mode. Cell dry weight, polysaccharide, sugar and cellulose concentrations were monitored and cellulose was characterized by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The highest cellulose yield (1.637 g/L) was obtained in SCP50-7d, which molasses of 1/2 ratio for 7 days by static semi-continuous operation mode. The results show that BC can be highly produced by G. xylinus in molasses with static semi-continuous process than batch process. We claimed that low-cost medium with semi-continuous operation mode in static culture is a good candidate for industrial scale BC productions. Copyright © 2014 Elsevier Ltd. All rights reserved.

    "Temulose" is the trade name for a water-soluble molasses produced on a large scale (300-400 tonnes per year) as a byproduct of the fiberboard industry. The feedstock for Temulose is predominantly a single species of pine ( Pinus taeda ) grown and harvested in stands in southeastern Texas. Because of the method of production, the molasses was predicted to consist of water-soluble hemicelluloses, mainly arabinoxylan-type and galactoglucomannan-type oligosaccharides, plus minor components of lignin, but no detailed structural study had been reported. The structure and composition of the molasses has now been deduced by a combination of MALDI-TOF mass spectrometry, size exclusion chromatography, proton and (13)C NMR techniques, and classic carbohydrate analysis. Limited acid hydrolysis released a series of galactoglucomannan oligosaccharides (GGMO) that were selectively recovered from the acid-labile arabinogalactan by precipitation with ethanol. The precipitate was named "Temulose brown sugar" because of its appearance, and is shown to consist of GGMO with a degree of polymerization (DP) from 4 to 13, with the major component being DP 5-8. The structure of these oligosaccharides is a β-1,4-linked backbone of Man and Glc residues, with occasional α-1,6 branching by single galactosyl units.

    Butyrate fermentation by immobilized Clostridium tyrobutyricum was successfully carried out in a fibrous bed bioreactor using cane molasses. Batch fermentations were conducted to investigate the influence of pH on the metabolism of the strain, and the results showed that the fermentation gave a highest butyrate production of 26.2 g l(-1) with yield of 0.47 g g(-1) and reactor productivity up to 4.13 g l(-1)h(-1) at pH 6.0. When repeated-batch fermentation was carried out, long-term operation with high butyrate yield, volumetric productivity was achieved. Several cane molasses pretreatment techniques were investigated, and it was found that sulfuric acid treatment gave better results regarding butyrate concentration (34.6+/-0.8 g l(-1)), yield (0.58+/-0.01 g g(-1)), and sugar utilization (90.8+/-0.9%). Also, fed-batch fermentation from cane molasses pretreated with sulfuric acid was performed to further increase the concentration of butyrate up to 55.2 g l(-1).

    Bank deposits in offshore financial centers may be used to evade taxes on interest income. A recent EU reform limits the scope for this type of tax evasion by introducing a withholding tax on interest income earned by EU households in Switzerland and several other offshore centers. This paper...... estimates the impact of the withholding tax on Swiss bank deposits held by EU residents while using non-EU residents who were not subject to the tax as a comparison group. We present evidence that Swiss bank deposits owned by EU residents declined by 30–40% relative to other Swiss bank deposits in two...... quarters immediately before and after the tax was introduced. We also present evidence suggesting that the drop in Swiss bank deposits was driven by behavioral responses aiming to escape the tax - such as the transfer of funds to bank accounts in other offshore centers and the transfer of formal ownership...

    In this study, physicochemical, rheological (steady, dynamic, and creep/recovery), and textural properties of yoghurt/molasses blends (0, 5, 10, and 15% molasses) were investigated. The blends showed shear thinning behavior, as described by Ostwald de Waele model (R(2) ( )≥ 0.955). Consistency coefficient value (K) of the blends decreased with increasing molasses concentration in the sample. Storage modulus (G') of blends was higher than loss modulus (G″), exhibiting weak gel-like behavior. Molasses addition decreased G' and G″ values. Temperature sweep tests indicated that blends followed Arrhenius relationship. A modified Cox-Merz rule was applicable using shift factors. Compliance values (J(t)) increased as molasses concentration increased, revealing that deformation stability and internal viscosity (η1) decreased with concentration. Creep behavior was characterized using Burger model. Obtained J data as a function of time could be satisfactorily fitted to Burger model (R(2) ( )≥ 0.994). The final percentage recovery of blends remarkably decreased with the increase of molasses concentration. Firmness, consistency, cohesiveness, and viscosity index values decreased with molasses addition. According to the results of the current study, molasses amount to be added to the yoghurt should be determined regarding rheological properties since resistance of the sample to deformation decreased with increase in molasses concentration. © The Author(s) 2015.

    Molasses wastewater is a high strength effluent of food industry such as distilleries, sugar and yeast production plants etc. It is characterized by a dark brown color and exhibits a high content in substances of recalcitrant nature such as melanoidins. In this study, electrocoagulation (EC) was studied as a post treatment step for biologically treated molasses wastewater with high nitrogen content obtained from a baker's yeast industry. Iron and copper electrodes were used in various forms; the influence and interaction of current density, molasses wastewater dilution, and reaction time, on COD, color, ammonium and nitrate removal rates and operating cost were studied and optimized through Box Behnken's response surface analysis. Reaction time varied from 0.5 to 4 h, current density varied from 5 to 40 mA/cm(2) and dilution from 0 to 90% (v/v expressed as water concentration). pH, conductivity and temperature measurements were also carried out during each experiment. From preliminary experiments, it was concluded that the application of aeration and sample dilution, considerably influenced the kinetics of the process. The obtained results showed that COD removal varied between 10 and 54%, corresponding to an operation cost ranging from 0.2 to 33 euro/kg COD removed. Significant removal rates were obtained for nitrogen as nitrate and ammonium (i.e. 70% ammonium removal). A linear relation of COD and ammonium to the design parameters was observed, while operation cost and nitrate removal responded in a curvilinear function. A low ratio of electrode surface to treated volume was used, associated to a low investment cost; in addition, iron wastes could be utilized as low cost electrodes i.e. iron fillings from lathes, aiming to a low operation cost due to electrodes replacement. In general, electrocoagulation proved to be an effective and low cost process for biologically treated molasses-wastewater treatment for additional removal of COD and nitrogen content and

    Bio-refineries produce large volumes of waste streams with high organic content, which are potentially interesting for further processing. Anaerobic digestion (AD) can be a key technology for treatment of these sidestreams, such as molasses. However, the high concentration of salts in molasses can cause inhibition of methanogenesis. In this research, concentrated and diluted molasses were subjected to biomethanation in two types of submerged anaerobic membrane bioreactors (AnMBRs): one with biogas recirculation and one with a vibrating membrane. Both reactors were compared in terms of methane production and membrane fouling. Biogas recirculation seemed to be a good way to avoid membrane fouling, while the trans membrane pressures in the vibrating MBR increased over time, due to cake layer formation and the absence of a mixing system. Stable methane production, up to 2.05 L L −1  d −1 and a concomitant COD removal of 94.4%, was obtained only when diluted molasses were used, since concentrated molasses caused a decrease in methane production and an increase in volatile fatty acids (VFA), indicating an inhibiting effect of concentrated molasses on AD. Real-time PCR results revealed a clear dominance of Methanosaetaceae over Methanosarcinaceae as the main acetoclastic methanogens in both AnMBRs. - Highlights: • An anaerobic membrane bioreactor (AnMBR) can be used to digest diluted molasses. • Biogas recirculation is a good way to avoid fouling in an AnMBR. • Trans membrane pressures in AnMBR with vibrating membrane increased over time. • Methanosaeta sp. were the dominant acetoclastic methanogens

    This paper focuses on links between landsliding and debris-flow activity in a ca. 4 km2-large drainage basin located at the northern foothills of the Central Swiss Alps. Debris-flow frequency of the recent past was reconstructed using dendrogeomorphic methods. In addition, the source area was mapped in detail to assess the spatial distribution of landslides, and to determine the connectivity between hillslopes and the channel network. The geomorphic map indicates that the hillslopes host abundant landslides sourced in Paleogene Flysch and Molasse sandstone-mudstone alternations. Major differences in the landscape architecture between the eastern and western sides were identified. In particular, the eastern segment is characterized by a >300'000 m2 large earth flow (Schimbrig landslide) that is 5-10 m deep. This flow experienced a phase of high slip rates >2m day-1 between September 1994 and May 1995, transferring a total of 350'000 m3 of material. In contrast, the western side is characterized by a network of deeply incised channels (>50 m) bordered by hillslopes that host landslides that generally measure abies (L.) Karst.) and firs (Abies alba Mill.). A total of 325 increment cores were sampled from 162 trees obviously influenced by past debris-flow activity. Preliminary analysis of the tree samples indicate that 64% of the tree grew up between 1900 and 2009. 34% of the tree samples showed germination dates between 1800 and 1900, and the remaining 2% of the sampled specimens germinated before 1800. Dendrogeomorphic analyses depict that nearly 50% of the sampled trees were affected by debris-flow activity in the 1990s. This period of high activity might be related to enhanced sediment transfer to the river system in response to the high slip rates of the Schimbrig earth slide between 1994 and 1995. Other periods of enhanced debris-flows activity seem to have occurred around 1960, 1950, 1940 and at the end of 19th century.

    We report the production of the functional trisaccharide 1-kestose, O-β-D-fructofuranosyl-(2→1)-β-D-fructofuranosyl α-D-glucopyranoside, by β-fructofuranosidase from Aspergillus japonicus using sugar cane molasses as substrate. Sucrose in cane sugar molasses acted as a fructosyl donor and acceptor for the enzyme. The tetrasaccharide nystose, O-β-D-fructofuranosyl-(2→1)-β-D-fructofuranosyl-(2→1)-β-D-fructofuranosyl α-D-glucopyranoside, was produced from 1-kestose. Cane sugar molasses mixed with water provided a better substrate solution for β-fructofuranosidase compared to undiluted molasses due to the high concentration of product inhibitors such as glucose and fructose in molasses. The maximum concentration of 1-kestose obtained was 84.9 mg/ml and the maximum production efficiency was 32.3% after 24 h reaction at 40 °C. The maximum efficiency of combined fructo-oligosaccharide (1-kestose and nystose) production was 40.6%. 1-Kestose was therefore produced via a fructosyl-transfer reaction catalyzed by β-fructofuranosidase from A. japonicus.

    This study investigated the feasibility of lipid production of Chlorella sp. from waste materials. Lipid-extracted microalgal biomass residues (LMBRs) and molasses were hydrolyzed, and their hydrolysates were analyzed. Five different hydrolysate mixture ratios (w/w) of LMBRs/molasses (1/0, 1/1, 1/4, 1/9, and 0/1) were used to cultivate Chlorella sp. The results showed that carbohydrate and protein were the two main compounds in the LMBRs, and carbohydrate was the main compound in the molasses. The highest biomass concentration of 5.58 g/L, Y biomass/sugars of 0.59 g/g, lipid productivity of 335 mg/L/day, and Y lipids/sugars of 0.25 g/g were obtained at the hydrolysate mixture ratio of LMBRs/molasses of 1/4. High C/N ratio promoted the conversion of sugars into lipids. The lipids extracted from Chlorella sp. shared similar lipid profile of soybean oil and is therefore a potential viable biodiesel feedstock. These results showed that Chlorella sp. can utilize mixed sugars and amino acids from LMBRs and molasses to accumulate lipids efficiently, thus reducing the cost of microalgal biodiesel production and improving its economic viability.

    Stimulating indigenous microbes to reduce heavy metals from highly toxic oxidized species to more benign reduced species is a promising groundwater remediation technique that has already seen successful field applications. Designing such a bio-remediation scheme requires a model incorporating the kinetics of nonlinear bio-geochemical interactions between multiple species. With this motivation, we performed a set of microcosm experiments in natural sediments and their indigenous pore water and microbes, generating simultaneous time series for concentrations of Cr(VI), an electron donor (both molasses and acetate were considered), and biomass. Molasses was found to undergo a rapid direct abiotic reaction which eliminated all Cr(VI) before any biomass had time to grow. This was not found in the acetate microcosms, and a distinct zero-order bio-reduction process was observed. Existing models were found inappropriate and a new set of three coupled governing equations representing these process dynamics were developed and their parameters calibrated against the time series from the acetate-amended microcosms. Cell suspension batch experiments were also performed to calibrate bio-reduction rates in the absence of electron donor and sediment. The donor used to initially grow the cells (molasses or acetate) was found not to impact the reduction rate constants in suspension, which were orders of magnitude larger than those explaining the natural media microcosm experiments. This suggests the limited utility of kinetics determined in suspension for remedial design. Scoping studies on the natural media microcosms were also performed, suggesting limited impact of foreign abiotic material and minimal effect of diffusion limitation in the vertical dimension. These analyses may be of independent value to future researchers.

    Highlights: • This study performs LCA analysis of sugarcane-based bioethanol production. • Energy and GHG balances are evaluated in the entire production chain. • Sensitivity analysis is performed to identify key influencing parameters. • Efficient cogeneration and biogas recovery enhances energy and climate gains. • Results of LCA studies and issues related to land use change impact are discussed. - Abstract: This study analyses the sustainability of fuel ethanol production from cane molasses in Indonesia. Life cycle assessment (LCA) is performed to evaluate the net emissions (climate change impact) and energy inputs (resource consumption) in the production chain. The lifecycle greenhouse gas (GHG) emissions in the production and use of ethanol are estimated at 29 gCO 2eq per MJ of ethanol produced which is a 67% reduction in comparison to gasoline emissions. Net Energy Value (NEV) and Net Renewable Energy Value (NREV) are −7 MJ/l and 17.7 MJ/l, while the energy yield ratio (ER) is 6.1. Economic allocation is chosen for dividing environmental burdens and resource consumption between sugar (i.e. main product) and molasses (i.e. co-product used for fuel production). Sensitivity analysis of various parameters is performed. The emissions and energy values are highly sensitive to sugarcane yield, ethanol yield, and the price of molasses. The use of sugarcane biomass residues (bagasse/trash) for efficient cogeneration, and different waste management options for the treatment of spent wash (effluent of distilleries) are also explored. Surplus bioelectricity generation in the efficient cogeneration plant, biogas recovery from wastewater treatment plant, and their use for fossil fuel substitution can help improve energy and environmental gains. The study also compares important results with other relevant international studies and discusses issues related to land use change (LUC) impact.

    Urea entry rates were measured in the body pool of Barbari kids using a single injection isotope dilution technique. The kids were divided into five groups (T 1 , T 2 , T 3 , T 4 and T 5 ) and they were fed different levels of urea molasses viz., 10, 25, 35, 40 and 0 percent to meet their DCP requirement along with concentrate mixture and oat hay as per A.R.C. recommendation. Urea entry rate was significantly higher (P 1 and the control group (T 5 without urea in their diets) than that of T 2 , T 3 and T 4 which were not significantly different from each other. (author)

    2003-01-01

    Full Text Available In this work, the catalytic role of chrysotile support on the acceleration of alcoholic fermentation under non-aseptic conditions by Saccharomyces cerevisiae was investigated. The fermentation medium employed consisted only of diluted sugar-cane molasses. In the batch fermentations process with immobilized yeasts, the initial rate of CO2 production increased roughly 27 % during the first 30 minutes, compared to systems containing no chrysotile. A study of continuous alcoholic fermentation with chrysotile in the reactor bed showed a higher ethanol production rate at the different dilution rates investigated compared to similar fermentations without chrysotile.

    Anaerobic fermentation technology was used to treat molasses wastewater. This study compared the hydrogen production capability of different fermentation types involving dark fermentation hydrogen production. The paper discussed the experiment including the results. It was found that the fermentation type changed by changing engineered control parameters in a continuous stirred tank reactor (CSTR). It was concluded that ethanol-type fermentation resulted in the largest hydrogen production capability, while butyric acid-type fermentation took second place followed by propionic acid-type fermentation.

    Using molasses wastewater as partial acidifying agent, a new Fenton-like catalyst (ACRM sm ) was prepared through a simple process of acidification and calcination using red mud as main material. With molasses wastewater, both the free alkali and the chemically bonded alkali in red mud were effectively removed under the action of H 2 SO 4 and molasses wastewater, and the prepared ACRM sm was a near-neutral catalyst. The ACRM sm preparation conditions were as follows: for 3 g of red mud, 9 mL of 0.7 mol/L H 2 SO 4 plus 2 g of molasses wastewater as the acidifying agent, calcination temperature 573 K, and calcination time 1 h. Iron phase of ACRM sm was mainly α-Fe 2 O 3 and trace amount of carbon existed in ACRM sm . The addition of molasses wastewater not only effectively reduced the consumption of H 2 SO 4 in acidification of red mud but also resulted in the generation of carbon and significantly improved the distribution of macropore in prepared ACRM sm . It was found that near-neutral pH of catalyst, generated carbon, and wide distribution of macropore were the main reasons for the high catalytic activity of ACRM sm . The generated carbon and wide distribution of macropore were entirely due to the molasses wastewater added. In degradation of orange II, ACRM sm retained most of its catalytic stability and activity after five recycling times, indicating ACRM sm had an excellent long-term stability in the Fenton-like process. Furthermore, the performance test of settling showed ACRM sm had an excellent settleability. ACRM sm was a safe and green catalytic material used in Fenton-like oxidation for wastewater treatment.

    Studies were conducted to find out whether inclusion of molasses had any effect on the fermentation quality and potential nutritive value of silage when wheat straw and poultry litter were ensiled with citrus pulp. A 4 x 2 factorial experiment in a randomized complete block design with four treatments (T) containing wheat straw, poultry litter and citrus pulp respectively on DM basis with 0 and 5% molasses, were prepared as follows-: T1 (75:25:0); T2 (60:25:15); T3 (45:25:30) and T4 (30:25:45). For each treatment in triplicate between 5-10 kg of thoroughly mixed material were ensiled for for a period of 60 days in 20-l hard plastic container laboratory silos, lined with a double layer of polythene bags. Inclusion of 5% molasses when ensiling wheat straw and poultry litter with 0, 15, 30 and 45% citrus pulp had no significant effect on pH, neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL) and in vitro OM digestibility. However, molasses resulted in a significant decrease in volatile fatty acids including N-butyric acid. There was a complete elimination of coliforms in all treatments, except in the silage that had neither molasses nor citrus pulp. There was a significant difference in titratable acidity levels between silage with 0 and 5% molasses, but this was only in silage with 30% citrus pulp. As the proportion of citrus pulp in silage increased from 0 to 45%, there was significant increase in silage acidity and also an increase in pH. However, there was no significant difference in pH between silage with 30 and 45% citrus pulp. There was a significant (P < 0.001) increase in in vitro OM digestibility from 0.33 to about 0.56 for silage with 0 and 45% citrus pulp respectively. It is concluded that when wheat straw and poultry litter are ensiled with citrus pulp, use of molasses offers no significant benefit inspite of the cost associated with its use. However, when no citrus pulp is included in the pre-mix, addition of some

    Following the Chernobyl disaster a large proportion of the Swiss population has had its faith in nuclear power severely shaken. On technical grounds an accident with such serious consequences for humans is not considered possible in Switzerland. A sound energy policy must be conceived on long-term considerations and should not be altered needlessly in the short term. Consequently the aims of security of power supply, energy savings and oil substitution must be pursued in the future. A change in energy policy by the Swiss power generation industry, as a result of Chernobyl, is not considered necessary

  15. Tax Evasion and Swiss Bank Deposits

    Bank deposits in jurisdictions with banking secrecy constitute an effective tool to evade taxes on interest income. A recent EU reform reduces the scope for this type of tax evasion by introducing a source tax on interest income earned by EU residents in Switzerland and several other jurisdictions...... with banking secrecy. In this paper, we estimate the impact of the source tax on Swiss bank deposits held by EU residents while using that non-EU residents were not subject to the tax to apply a natural experiment methodology. We find that the 15% source tax caused Swiss bank deposits of EU residents to drop...

    2008-06-01

    Fermentation of 1.5g/l of Indian black tea, sweetened with adequate quantities of molasses (containing approx. 70g/l, 50g/l and 35g/l of sucrose), was conducted using domestic Kombucha. Inoculation was performed with 10% of fermentation broth from a previous process. The fermentation in cylindrical vessels containing 2l of liquid phase, was carried out at 22±1°C for 14 days, with periodical sampling, to measure pH, content of acids (total, acetic and l-lactic), content of remaining sucrose, and the yield of biomass at the end of fermentation. A product with 70g/l sucrose from molasses corresponds to an optimal concentration of carbon source, which provided metabolites with high pH, a low content of less desired acetic acid, a high content of highly desired l-lactic acid, an acceptable content of total acids and the highest possible level of utilisation of sucrose.

    The research aimed to study the characteristic and yield of Mozzarella cheese produced by using rennin enzyme from Mucor miehei which is grown at rice bran and molasses medium. The popularity of Mozzarella cheese in Indonesia is increased caused by the spreading of western foods in Indonesia such as pizza and spaghetti that use Mozzarella cheese for ingredient. In Italy, Mozzarella and pizza cheeses are dominating 78% of the total Italian Cheese products. In producing Mozzarella cheese, rennin enzyme is always used as milk coagulant. Even now, Indonesia has not produced the rennin enzyme yet. The rennin enzyme from Mucor miehei growing at rice bran and molases medium which have the availability can be managed purposively within short period of time. The completly randomized design methode used to get the best crude extracts of Mucor miehei rennin enzyme, then is employed to produce mozzarella cheese. The result of Mozzarella cheese has various characteristics such as the yield’s weight is 9.1%, which consists of 50% moisture content, 36.64% peotein levels, 0.1 melting ability and 82.72% stretch ability or 0.79/N. With that characteristic it is concluded that rennin enzyme from Mucor miehei grown at rice bran molasses medium has the potential to alternatively subtitute calf rennin to produce Mozzarella cheese, and the characteristics fulfill the standart.

    Full Text Available Natural adhesion of Saccharomyces cerevisiae onto sugar beet pulp (SBP is a very simple and cheap immobilization method for retaining high cells density in the ethanol fermentation system. In the present study, yeast cells were immobilized by adhesion onto SBP suspended in the synthetic culture media under different conditions such as: glucose concentration (100, 120 and 150 g/l, inoculum concentration (5, 10 and 15 g/l dry mass and temperature (25, 30, 35 and 40°C. In order to estimate the optimal immobilization conditions the yeast cells retention (R, after each immobilization experiment was analyzed. The highest R value of 0.486 g dry mass yeast /g dry mass SBP was obtained at 30°C, glucose concentration of 150 g/l, and inoculum concentration of 15 g/l. The yeast immobilized under these conditions was used for ethanol fermentation of sugar beet molasses containing 150.2 g/l of reducing sugar. Efficient ethanol fermentation (ethanol concentration of 70.57 g/l, fermentation efficiency 93.98% of sugar beet molasses was achieved using S. cerevisiae immobilized by natural adhesion on SBP.

    We evaluated the feasibility of co-digesting molasses wastewater and sewage sludge in a two-stage hydrogen- and methane-producing system. The highest energy was recovered at the 21-h hydraulic retention time (HRT) of the first hydrogenic reactor and at 56-h HRT of the secondary methanogenic reactor. Hence, the two-stage system recovered 1,822 kJ from 1 L of the mixed wastes (19.7: hydrogenic reactor plus, 1,802 kJ L(-1): methanogenic reactor). Despite the overloaded VFA-run with a short HRT of 56 h, the GAC-CH4 reactor increased methane production rate and yields due to enhanced pH buffer capacity. An RNA-based community analysis showed that the Ethanoligenens and Methanosaeta dominated the hydrogen and methane bioreactor, respectively. The two-stage system of co-digesting molasses and sewage sludge is particularly cost-effective due to non-pretreatment of sewage sludge.

    Highlights: • Sugarcane biorefinery in Thailand is evaluated using the eco-efficiency concept. • Green cane along with cane trash use for electricity yields highest eco-efficiency. • Proposed biorefinery system increases eco-efficiency by 20–70%. - Abstract: The study aims to evaluate the sugarcane biorefinery and molasses ethanol production in Thailand using the combined environmental and economic sustainability indicator, so called “Eco-efficiency”. Four sugarcane biorefinery scenarios in Thailand are evaluated. The total output values (US$) and the life cycle greenhouse gas (GHG) emissions (kg CO 2 eq) are selected as the indicators for characterizing economic and environmental performance, respectively. The results show that the biorefinery system of mechanized farming along with cane trash utilization for power generation yields the highest eco-efficiency. The benefits come from the increased value added of the biorefinery together with the decreased GHG emissions of the biorefinery system. As compared to the base case scenario, the new systems proposed result in the eco-efficiency improvement by around 20–70%. The biorefinery concept induces reduction of GHG emissions attributed to molasses ethanol. Green cane production and harvesting results in further lowering of the GHG emissions. Integration of sugarcane biomass utilization across the entire sugarcane complex would enhance the sustainability of the sugarcane production system.

    Very high gravity (VHG) technology was employed on industrial scale to produce ethanol from molasses (fermented) as well as by-products formation estimation. The effect of different Brix° (32, 36 and 40) air-flow rates (0.00, 0.20, 0.40, and 0.60vvm) was studied on ethanol production. The maximum ethanol production was recorded to be 12.2% (v/v) at 40 Brix° with 0.2vvm air-flow rate. At optimum level aeration and 40 Brix° VHG, the residual sugar level was recorded in the range of 12.5-18.5g/L, whereas the viable cell count remained constant up to 50h of fermentation and dry matter production increased with fermentation time. Both water and steam consumption reduced significantly under optimum conditions of Brix° and aeration rate with compromising the ethanol production. Results revealed VHG with continuous air flow is viable technique to reduce the ethanol production cost form molasses at commercial scale. Copyright © 2017. Published by Elsevier Editora Ltda.

    In commercial ethanol production procedures often use sugar cane molasses as a raw material due to their abundance and low costs. The most employed microorganisms used for fermentation is Saccharomyces cerevisiae yeasts due to its ability to hydrolyze sucrose from sugar cane molasses into glucose and fructose, two easily assimilable hexoses.The aim of this study was to evaluate the effect of gamma irradiation on the activity of S. cerevisiae in the ethanol production yeast cells exposed to different doses of gamma rays (0.05, 0.10, 0.2, 0.4, 0.6, 0.8 and 1.0 kGy. The sugar cane substrate was optimized after maintaining deferent levels of sugar concentrations (12-21%), medium ph (4.0-5.5), incubation temperature (25-40 degree C) and rate of fermentation (24-168) h. Data showed that rate of ethanol production was maximum by using the irradiated S. cerevisiae cells at 0.1 kGy. dose at fermentation conditions as 15% sugar concentration, initial ph 4.5, incubation temperature 30 degree C, fermentation time 96 h at a fermentation medium volume 250 ml found in 500 ml erlenmyer flasks.

    Clostridium acetobutylicum B530 has ability to convert sugar into biobutanol through two phases, i.e. acidogenic and solventogenic. This fermentation process is often hampered by high raw material cost and low product yield. In order to suppress the production cost, the molasses, a byproduct of sugar cane process production, was used as carbon source in this research. Molasses has nitrogen content in a small amount, thus could be negating the beef extract component, which is expected not to affect the growth of C. acetobutylicum B530 and also can reduce the production cost. In addition, a certain amount of Fe2+ (ferrous ion), a precursor in the formation of the enzyme ferredoxin, was added to the fermentation medium to contribute in the synthesis of acetyl-CoA, so that the formation of acidogenic products such as butyric acid and acetic acid is affected. This study aimed to investigate the effect of ferrous ion and the medium composition in acidogenic phase. The addition of 20 ppm FeSO4.7H2O in the fermentation medium without beef extract can increase the concentration of butyric acid by 20% at a temperature of 35°C, while acetic acid concentration decreased by 6%. According to those results, it is expected that the product selectivity of butanol will increase in solventogenic phase. In addition, the removal of beef extract in the fermentation medium does not affect the kinetics of growth of C. acetobutylicum B530.

    Switzerland and the European Union share common values and have peaceful and well functioning economic and political agreements. Nevertheless, the Swiss banking secrecy is definitely a thorn in the EU's flesh, especially because of tax fraud or money laundering. Since the existence of the Swiss banking secrecy it has been associated with holocaust money, tax evasion, potentates' money etc. and also has been confronted with espionage attacks by foreign authorities and various other disputes.

    Although there are quite good examples of quality management in Swiss hospitals available (the guidelines of quality management in the Swiss hospital etc.), the distribution of measures of quality assurance in Swiss hospitals is insufficient and focuses more on Hotel services and technical equipment rather than on the care by physicians and nurses. Beginning with Jan. 1, 1998, contracts of quality assurance between health care providers and sponsors have to be presented according to the new health insurance act. These contracts are proofed periodically by a national office. This necessitates a country-wide introduction of statistics (ICD-codes) and computerization. This is currently only in the process of realization. Additionally, hospitals and medical practices already undertake a comprehensive quality control due to local and regional initiatives. The society of Swiss physicians FMH supports mainly three areas: compulsory continuing medical education (80 hours annually, including 50 hours in recognized meetings), the development of guidelines by medical societies, and data collection including the development of a network for measures of quality assurance. The ISO-standard 9000 was changed for health care as ordered by the NAQ (National workshop for quality assurance) and the FMH. It is supposed to be used mainly for the certification of facilities for continuing medical education, perhaps also for the certification of hospitals.

    2010-07-01

    This report issued by the Paul Scherrer Institute (PSI) in Switzerland takes a look at the design concepts behind the institute's SwissFEL X-ray Laser facility. The goal of SwissFEL is to provide a source of extremely bright and short X-ray pulses enabling scientific discoveries in a wide range of disciplines to be made, from fundamental research through to applied science. The eminent scientific need for such an X-ray source which is well documented in the SwissFEL Science Case Report is noted. The technical design of SwissFEL has to keep a delicate balance between the demand by experimentalists for breathtaking performance in terms of photon beam properties on the one hand, and essential requirements for a user facility, such as confidence in technical feasibility, reliable and stable functioning and economy of installation and operation on the other hand. The baseline design which has been defined is discussed. This relies entirely on state-of-the-art technologies without fundamental feasibility issues. This SwissFEL Conceptual Design Report describes the technical concepts and parameters used for this baseline design. The report discusses the design strategy, the choice of parameters and the simulation of the accelerator unit and undulator. The photon beam layout is discussed, as is the installation's tera hertz pump source. The components of the facility, including the laser and radio-frequency systems, timing and synchronisation systems, magnets, undulators, and mechanical support systems are discussed. Further, the concepts behind electron beam diagnostics, vacuum equipment as well as control and feedback systems are discussed. The building layout is described and safety issues are discussed.

    To investigate the effect of molasses concentration, initial pH of molasses medium, and inoculum's size to maximize ethanol and minimize methanol, fusel alcohols, acetic acid and aldehydes in the fermentation mash in industrial fermentors. Initial studies to optimize temperature, nitrogen source, phosphorous source, sulfur supplement and minerals were performed. The essential nutrients were urea (2 kg in 60 m(3)), 0.5 l each of commercial phosphoric acid and sulfuric acid (for pH control) added at the inoculum preparation stage only. Yields of ethanol, methanol, fusel alcohols, total acids and aldehydes per 100-l fermentation broth were monitored. Molasses at 29 degrees Brix (degree of dissolved sugars in water), initial pH 4.5, inoculum size 30% (v/v) and anaerobic fermentation supported maximum ethanol (7.8%) with Y(P/S) = 238 l ethanol per tonne molasses (96.5% yield) (8.2% increase in yield), and had significantly lower values of byproducts than those in control experiments. Optimization of process variables resulted in higher ethanol yield (8.2%) and reduced yield of methanol, fusel alcohols, acids and aldehydes. More than 5% substrate is converted into byproducts. Eliminating or reducing their formation can increase ethanol yield by Saccharomyces cerevisiae, decrease the overall cost of fermentation process and improve the quality of ethanol.

    Full Text Available Leucaena silage was supplemented with different levels of molasses and urea to study its nutritive value and in vitro rumen fermentation efficiency. The ensiling study was randomly assigned according to a 3×3 factorial arrangement in which the first factor was molasses (M supplement at 0%, 1%, and 2% of crop dry matter (DM and the second was urea (U supplement as 0%, 0.5%, and 1% of the crop DM, respectively. After 28 days of ensiling, the silage samples were collected and analyzed for chemical composition. All the nine Leucaena silages were kept for study of rumen fermentation efficiency using in vitro gas production techniques. The present result shows that supplementation of U or M did not affect DM, organic matter, neutral detergent fiber, and acid detergent fiber content in the silage. However, increasing level of U supplementation increased crude protein content while M level did not show any effect. Moreover, the combination of U and M supplement decreased the content of mimosine concentration especially with M2U1 (molasses 2% and urea 1% silage. The result of the in vitro study shows that gas production kinetics, cumulation gas at 96 h and in vitro true digestibility increased with the increasing level of U and M supplementation especially in the combination treatments. Supplementation of M and U resulted in increasing propionic acid and total volatile fatty acid whereas, acetic acid, butyric acid concentrations and methane production were not changed. In addition, increasing U level supplementation increased NH3-N concentration. Result from real-time polymerase chain reaction revealed a significant effect on total bacteria, whereas F. succinogenes and R. flavefaciens population while R. albus was not affected by the M and U supplementation. Based on this study, it could be concluded that M and urea U supplementation could improve the nutritive value of Leucaena silage and enhance in vitro rumen fermentation efficiency. This study also

    Aerobic granulation technology is applied to treat domestic and industrial wastewater. The Aerobic granular sludge (AGS) cultivated has strong properties that appears to be denser and compact in physiological structure compared to the conventional activated sludge. It offers rapid settling for solid:liquid separation in wastewater treatment. Aerobic granules were developed using sequencing batch reactor (SBR) with intermittent aerobic - anaerobic mode with 8 cycles in 24 hr. This study examined the settling velocity performance of cultivated aerobic granular sludge (AGS) and aerobic granular sludge molasses (AGSM). The elemental composition in both AGS and AGSM were determined using X-ray fluorescence (XRF). The results showed that AGSM has higher settling velocity 30.5 m/h compared to AGS.

    During the course of our research into the use of cane by-products from sugar manufacturing, we have studied the isolation and structural determination of bioactive compounds present in sugarcane molasses. In this study, dehydrodiconiferylalcohol-9'-O-beta-D-glucopyranoside (1) and isoorientin-7, 3'-O-dimethyl ether (2) were isolated as antibacterial active compounds against cariogenic bacteria. Their structures were elucidated by (1)H-NMR, (13)C-NMR and ESI-MS. The activities of these isolated compounds against Streptococcus mutans and Streptococcus sobrinus were assessed by a minimum inhibitory concentration (MIC) test. The MICs of compounds 1 and 2 against both S. mutans and S. sobrinus were >4 mg/mL and 4 mg/mL, respectively.

    Corynebacterium glutamicum (ATCC 13058) was used for glutamic acid production from sugar cane molasses which contain sufficient. The addition of 5 units ml 4 of penicillin G was superior in glutamic acid production (11.5 g L 4 ). Tweens and their saturated fatty acids were effective on the accumulation of glutamic acid in the culture medium and the maximum yield (16.6 g L 4 ) was the addition of 5 mg ml 4 Tween 40. Gamma irradiation prior to Tween-40 treatment of bacterial cells resulted in an obvious increase in glutamic acid production and it was maximum (23.72 g L 4 ) at 0.1 k Gy exposure dose of inocula. 5 tabs

    2010-11-01

    A study of bio-hydrogen production was performed in a continuous flow anaerobic fermentation reactor (with an available volume of 5.4 L). The continuous stirred tank reactor (CSTR) for bio-hydrogen production was operated under the organic loading rates (OLR) of 8-32 kg COD/m3 reactor/d (COD: chemical oxygen demand) with molasses as the substrate. The maximum hydrogen production yield of 8.19 L/d was obtained in the reactor with the OLR increased from 8 kg COD/m3 reactor/d to 24 kg COD/m3 d. However, the hydrogen production and volatile fatty acids (VFAs) drastically decreased at an OLR of 32 kg COD/m3 reactor/d. Ethanoi, acetic, butyric and propionic were the main liquid fermentation products with the percentages of 31%, 24%, 20% and 18%, which formed the mixed-type fermentation.

    The marine molasses of Fribourg (Switzerland) is an area where the cliff collapses and rockfalls are quite frequent and difficult to predict due to this particular lithology, a poorly consolidated greywacke. Because of some recent rockfall events, the situation became critical especially in the valley of Gotteron where a big block has slightly moved down and might destroy a house in case of rupture. The cliff made of jointed sandstone and thin layers of clay and siltstone presents many fractures, joints and massive cross bedding surfaces which increases the possibility of slab failure. This paper presents a detailed structural analysis of the cliff and the identification of the potential failure mechanisms. The methodology is about combining field observation and terrestrial LiDAR scanning point cloud in order to assess the stability of potential slope instabilities of molasses. Three LiDAR scans were done i) to extract discontinuity families depending to the dip and the dip direction of joints and ii) to run kinematic tests in order to identify responsible sets for each potential failure mechanisms. Raw point clouds were processed using IMAlign module of Polyworks and CloudCompare software. The structural analysis based on COLTOP 3D (Jaboyedoff et al. 2007) allowed the identification of four discontinuity sets that were not measured in the field. Two different failure mechanisms have been identified as critical: i) planar sliding which is the main responsible mechanism of the present fallen block and ii) wedge sliding. The planar sliding is defined by the discontinuity sets J1 and J5 with a direction parallel to the slope and with a steep dip angle. The wedges, defined by couples of discontinuity sets, contribute to increase cracks' opening and to the detachment of slabs. The use of TLS combined with field survey provides us a first interpretation of instabilities and a very promising structural analysis.

    We have synthesized and electrochemically tested a carbon sample that was suitable as anode for lithium secondary battery. The synthesis was based on the use of the palygorskite clay as template and sugar cane molasses as carbon source. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, Brunauer–Emmett–Teller (BET) measurements and High Resolution Transmission Electron Microscope (HRTEM) analysis showed that the nanometric carbon material has a highly disordered graphene-like wrinkled structure and large specific surface area (467 m{sup 2} g{sup −1}). The compositional characterization revealed a 14% of heteroatoms-containing groups (O, H, N, S) doping the as-prepared carbon. Thermophysical measurements revealed the good thermal stability and an acceptable thermal diffusivity (9·10{sup −7} m{sup 2} s{sup −1}) and conductivity (1.1 W m{sup −1} K{sup −1}) of this carbon. The electrical properties showed an electronic conductivity of hole-like carriers of approximately one S/cm in a 173–293 K range. The testing of this material as anodes in a secondary lithium battery displayed a high specific capacity and excellent performance in terms of number of cycles. A high reversible capacity of 356 mA h g{sup −1} was reached. - Graphical abstract: TEM image and electrochemistry behavior of a new graphene oxide-like carbon. - Highlights: • A high disordered graphene oxide-like conducting carbon is reported. • The synthesis was based on palygorskite and sugar cane molasses as precursors. • The disordered conducting carbon is composed of doped- graphene heterogeneous domains. • This material combines a large specific surface area and high electric conductivity. • The thermophysical and electrochemical properties of this material reveal adequate behavior.

    The extracted sugarcane molasses-melanoidins showed the presence of Mn (8.20), Cr (2.97), Zn (16.61), Cu (2.55), Fe (373.95), Pb (2.59), and Ni (4.18 mg L -1 ) along with mixture of other organic compounds which have endocrine-disrupting chemicals (EDCs) properties. A consortium of aerobic bacteria comprising Klebsiella pneumoniae (KU321273), Salmonella enteric (KU726954), Enterobacter aerogenes (KU726955), and Enterobacter cloacae (KU726957) showed the optimum decolourisation of molasses-melanoidins up to 81% through co-metabolism in the presence of glucose (1.0%) and peptone (0.2%) as a carbon and nitrogen source, respectively. The absorption spectrum scanning by UV-visible spectrophotometer between 200 and 700 nm revealed reductions of absorption spectrum of organic compounds present in bacterial degraded sample of melanoidins in range of 200-450 nm compared to control. The degradation and decolourisation of melanoidins by bacterial consortium was noted by induction of manganese peroxidase and laccase activities in sample supernatant. Furthermore, the TLC and HPLC analysis of bacterial decolourised melanoidins also showed degradation and reduction of absorption peak at (295 nm), respectively. Furthermore, FT-IR and GC-MS analysis also showed the change of functional group and disappearance of ion peaks. This indicated the degradation and depolymerisation of melanoidins and cleavage of C=C, C=O and C≡N conjugated bonds which resulted in reduction of colour. The metabolic analysis also showed the disappearance of some organic compounds and generation of new metabolites. Furthermore, the seed germination test using Phaseolus mungo L. showed toxicity reduction in decolourized effluent.

    The hard X-ray laser SwissFEL at the Paul Scherrer Institute is currently being commissioned and will soon become available for users. In the current article the laser facility is presented, an integral part of the user facility, as most time-resolved experiments will require a versatile optical laser infrastructure and precise information about the relative delay between the X-ray and optical pulse. The important key parameters are a high availability and long-term stability while providing advanced laser performance in the wavelength range from ultraviolet to terahertz. The concept of integrating a Ti:sapphire laser amplifier system with subsequent frequency conversion stages and drift compensation into the SwissFEL facility environment for successful 24 h/7 d user operation is described.

  3. Swiss cheese and a cheesy CMB

    It has been argued that the Swiss-Cheese cosmology can mimic Dark Energy, when it comes to the observed luminosity distance-redshift relation. Besides the fact that this effect tends to disappear on average over random directions, we show in this work that based on the Rees-Sciama effect on the cosmic microwave background (CMB), the Swiss-Cheese model can be ruled out if all holes have a radius larger than about 35 Mpc. We also show that for smaller holes, the CMB is not observably affected, and that the small holes can still mimic Dark Energy, albeit in special directions, as opposed to previous conclusions in the literature. However, in this limit, the probability of looking in a special direction where the luminosity of supernovae is sufficiently supressed becomes very small, at least in the case of a lattice of spherical holes considered in this paper

    A review of the conference held on 18th April 1985 in Bern at the General Assembly of the Swiss Pool for assurance against earthquakes. The total Swiss energy consumption in 1984 showed an increase of 4.3% over that of 1983, and the contribution of electricity to this total in 1984 was about 4.5% higher than in the previous year. Progress in increasing the hydroelectric output cannot make up the future demand to be expected, and nuclear energy must be looked to for the increased supply. In 1984 the five nuclear generating stations - Beznau I and II, Muehleberg, Goesgen and Leibstadt furnished about 17.4 milliards kWh (35.4%), a total capacity of about 2,900 MW, and general approval has been given for the Kaiseraugst station.

    Surveillance of the Swiss nuclear installations with regard to nuclear safety, including radiation protection, is among the tasks of the Swiss Federal Nuclear Safety Inspectorate (HSK). Five nuclear power plants are operational in Switzerland: the three units Beznau I and II and Muehleberg with electrical capacities in the range of 300 to 400 MWe, and the two units Goesgen and Leibstadt with capacities between 900 and 1200 MWe. These are light water reactors; at Beznau and Goesgen of the PWR type, and at Muehleberg and Leibstadt of the BWR type. Research reactors of thermal capacities below 10 MWth are operational at the Paul Scherrer Institute (PSI), at the Swiss Federal Institute of Technology Lausanne and at the University of Basel. Further subject to HSK`s supervision are all activities at PSI involving nuclear fuel or ionizing radiation, the shut-down experimental reactor of Lucens, the exploration, in Switzerland, of final disposal facilities for radwaste and the interim radwaste storage facilities. The report first deals with the nuclear power and covers, in individual sections, the aspects of installation safety, radiation protection as well as personnel and organization, and the resulting overall impression from the point of view of HSK. In chapter 5, the corresponding information is given for research installations. Chapter 6, on radwaste disposal, is dedicated to the treatment of waste, waste from reprocessing, interim storage and exploration by NAGRA. In chapter 7, the status of emergency planning in the nuclear power plants` proximity is reported. Certificates issued for the transport of radioactive materials are dealt with in chapter 8. Finally chapter 9 goes into general questions relating to the safety of nuclear installations. All in all, the safety of operation of the Swiss nuclear installations, in the period of 1994, is judged as good by HSK. (author) 11 figs., 13 tabs.

(1) UniProtKB is a comprehensive protein sequence knowledgebase that consists of two sections: UniProtKB/Swiss-Prot, which contains manually annotated entries, and UniProtKB/TrEMBL, which contains computer-annotated entries. UniProtKB/Swiss-Prot entries contain information curated by biologists and provide users with cross-links to about 100 external databases and with access to additional information or tools. (2) The UniRef databases (UniRef100, UniRef90, and UniRef50) define clusters of protein sequences that share 100, 90, or 50% identity. (3) The UniParc database stores and maps all publicly available protein sequence data, including obsolete data excluded from UniProtKB. The UniProt databases can be accessed online (http://www.uniprot.org/) or downloaded in several formats (ftp://ftp.uniprot.org/pub). New releases are published every 2 weeks. The purpose of this chapter is to present a guided tour of a UniProtKB/Swiss-Prot entry, paying particular attention to the specificities of plant protein annotation. We will also present some of the tools and databases that are linked to each entry.

    We study the effect of inhomogeneities on light propagation. The Sachs equations are solved numerically in the Swiss-cheese models with inhomogeneities modeled by the Lemaitre-Tolman solutions. Our results imply that, within the models we study, inhomogeneities may partially mimic the accelerated expansion of the Universe provided the light propagates through regions with lower than the average density. The effect of inhomogeneities is small and full randomization of the photons' trajectories reduces it to an insignificant level.

    Fibroadenoma 5 cm or more is called giant fibroadenoma. Giant fibroadenoma can distort the shape of breast and causes asymmetry, so it should be excised. There are several techniques for excision of giant fibroadenoma. In our technique we remove them through cosmetically acceptable circumareolar incision to maintain the shape and symmetry of breast. The objectives were to assess the cosmetic results of Swiss roll operation for giant fibroadenoma. The study was conducted for six years from January, 2002 to December, 2007. Seventy patients of giant fibroadenoma were included in this study. They were diagnosed on history and clinical examination supported by ultrasound and postoperative histopathological examination. Data were collected from outpatient department and operation theatre. Swiss roll operation was performed under general anaesthesia. Mean tumor size was 6.38 cm. Three cm and 4 cm incisions were used for tumour 6 cm in size respectively. Skin closed with Vicryl 3/0 subcuticular stitches. Sixteen out of 70 patients had no scar while others hadminimal scar. All patients had normal shape and symmetry of breast. On histopathology fibroadenoma was confirmed. Giant fibroadenoma should be removed through cosmetically acceptable cicumareolar incision especially in unmarried young females who have small breast. Swiss-roll operation is superior in maintaining the shape and symmetry of breast. No major complication was found in our series except seroma formation in 10 patients.

    In summer 2009, the Federal Council mandated the Departement of the Environment, Transport, Energy and Communication (DETEC) to develop a Swiss adaptation strategy. This strategy aims to coordinate the efforts of all federal departments involved in adaptation, and to provide them with the necessary basic information. For the development of the Swiss adaptation strategy the following principles are fundamental. (1.) The strategy aims to achieve the overarching objectives of harnessing the opportunities that climate change presents, minimizing the risks of climate change to people and assets, and to increases the adaptive capacity of all resources. (2) The strategy is based on the most recent scientific knowledge about climate change and climate change impacts. (3.) It is based in on a sound and comprehensive analysis of climate change risks. (4.) It includes strategic goals for the sectors that are most vulnerable to climate change, i.e., water management, biodiversity management, agriculture, forestry, natural hazard prevention, health care, energy generation, tourism, land use. (5.) It thoroughly analyzes the interfaces between the sectoral strategies in order solve existing conflicts and profit form existing synergies. The Swiss Adaptation Strategy will be completed and submitted to the Federal Council by the End of 2011.

    We consider a Swiss Cheese model with a random arrangement of Lemaȋtre-Tolman-Bondi holes in ΛCDM cheese. We study two kinds of holes with radius r b =50 h −1  Mpc, with either an underdense or an overdense centre, called the open and closed case, respectively. We calculate the effect of the holes on the temperature, angular diameter distance and, for the first time in Swiss Cheese models, shear of the CMB . We quantify the systematic shift of the mean and the statistical scatter, and calculate the power spectra. In the open case, the temperature power spectrum is three orders of magnitude below the linear ISW spectrum. It is sensitive to the details of the hole, in the closed case the amplitude is two orders of magnitude smaller. In contrast, the power spectra of the distance and shear are more robust, and agree with perturbation theory and previous Swiss Cheese results. We do not find a statistically significant mean shift in the sky average of the angular diameter distance, and obtain the 95% limit |Δ D A / D-bar A |∼< 10 −4 . We consider the argument that areas of spherical surfaces are nearly unaffected by perturbations, which is often invoked in light propagation calculations. The closed case is consistent with this at 1σ, whereas in the open case the probability is only 1.4%

    Full Text Available Polyhydroxyalkanoates (PHA are biodegradable and biocompatible green thermoplastics, synthesized by wide variety of bacteria as an intracellular carbon and energy storage intermediate. They are used as an alternative to nonrenewable petroleum derived plastics. The current interest in these biopolyesters is stimulated by the search for cost-effective capitalized production. This paper attempts to achieve maximized production rate from recombinant system using inexpensive substrate. Molasses from agro-industrial waste was used to produce PHA from recombinant E.coli in batch culture. PHA yield in molasses (3.06g/L ± 0.05-75.5% was higher than that of sucrose (2.5g/L ± 0.05 - 65.1%. Properties of the polymer produced from molasses and sucrose were analyzed by DSC, TGA, DTA, GC/MS, TLC and optical rotation studies. The findings suggested that molasses enhanced PHA production in recombinant E.coli.

    The aim of this study was to determine the effect of molasses and lactic acid bacteria (LAB) on the chemical composition, silage fermentation characteristics, and in vitro ruminal fermentation parameters of an ensiled potato-wheat straw mixture in a completely randomized design with 4 replicates. Wheat straw was harvested at full maturity and potato tuber when the leaves turned yellowish. The potato-wheat straw (57:43 ratio, DM basis) mixture was treated with molasses, LAB, or a combination. Lalsil Fresh LB (Lallemand, France; containing NCIMB 40788) or Lalsil MS01 (Lallemand, France; containing MA18/5U and MA126/4U) were each applied at a rate of 3 × 10 cfu/g of fresh material. Treatments were mixed potato-wheat straw silage (PWSS) without additive, PWSS inoculated with Lalsil Fresh LB, PWSS inoculated with Lalsil MS01, PWSS + 5% molasses, PWSS inoculated with Lalsil Fresh LB + 5% molasses, PWSS inoculated with Lalsil MS01 + 5% molasses, and corn silage (CS). The compaction densities of PWSS treatments and CS were approximately 850 and 980 kg wet matter/m, respectively. After anaerobic storage for 90 d, chemical composition, silage fermentation characteristics, in vitro gas production (GP), estimated OM disappearance (OMD), ammonia-N, VFA, microbial CP (MCP) production, and cellulolytic bacteria count were determined. Compared to CS, PWSS had greater ( butyric acids concentrations. When PWSS was treated with molasses, LAB, or both, the contents of CP and lactic and acetic acids increased, whereas NDFom, ammonia-N, and butyric acid decreased ( fermentation quality of PWSS was lesser than that of CS. However, addition of molasses and molasses + LAB improved fermentation quality of PWSS.

    Full Text Available ABSTRACT The invasion of exotic species is considered to be a major threat to the preservation of biodiversity. In the Parque Nacional de Brasília (National Park of Brasília, the invasive Melinis minutiflora (molasses grass occupies more than 10 % of the area of the park. The present, long-term, study compared two treatments of exposure to molasses grass: 1 fire and 2 integrated management (fire + herbicide sprays + manual removal. The aerial biomass of molasses grass in the experimental area initially represented ca. 55 % of the total aerial biomass, a percentage that apparently did not influence native plant species richness at this site. Fire alone was not sufficient to control molasses grass, which attained its pre-treatment biomass values after two years. Integrated management reduced, and maintained, biomass to less than 1 % of its original value after ten years, and maintained this level throughout the study, demonstrating that it is a promising strategy for the recovery of areas invaded by molasses grass in the Cerrado. However, because of the recolonization by molasses grass, long-term monitoring efforts are targeting outbreaks, which would require immediate intervention in order to maintain the native biological diversity of the region.

  20. How hard were the Jura mountains pushed?

    The mechanical twinning of calcite is believed to record past differential stress values, but validating results in the context of past tectonic situations has been rarely attempted. Using assumptions of linear gradients of stress components with depth, a stress gradient based on twinning palaeopiezometry is derived for the Swiss Molasse Basin, the indenter region to the Jura fold and thrust belt. When integrated into a model of the retrodeformed Jura-Molasse system, allowing horizontal stress concentration and conservation along the original taper geometry, the stress profile proves consistent with the position of the Jura-Molasse (ftb-indenter) transition. The model demonstrates mechanically why the Plateau Molasse portion of the Molasse Basin remained relatively undeformed when transmitting tectonic forces applied to the Jura mountains. (author)

    In the course of our work into the use of cane by-products, we have studied the isolation and structural determination of bioactive compounds in sugarcane molasses. In this study, three stereo isomers of syringyl glycerol 3'-O-beta-D-glucopyranoside, three stereo isomers of guaiacyl glycerol 3'-O-beta-D-glucopyranoside, a syringyl glycerol 2'-O-beta-D-glucopyranoside, tachioside and a 2,3-dihydro-3,5-dihydroxy-6-methyl-4-(H)-pyran-4-one (DDMP) were isolated from the 25% methanol eluate by Amberlite XAD-2 column chromatography of sugarcane molasses. The structures of these compounds were determined on the basis of spectroscopic evidence. These isolated compounds were examined for their scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical species, and for their inhibitory activity against mushroom tyrosinase. All of the isolated compounds showed DPPH radical scavenging activity, while DDMP and tachioside showed mushroom tyrosinase inhibitory activity.

    Experiments were conducted in which urea/molasses liquid feed along with a limited amount of intact protein and cereal forage was fed to lactating cows, and compared with another group receiving conventional concentrate and roughage-based rations. Voluntary consumption of liquid feed by cows was satisfactory. There was no significant difference in the milk yield between the two groups. The higher consumption of metabolizable energy and digestible crude protein by experimental cows from liquid feed was not reflected in their milk yields or body weights. Various other parameters such as digestibilities of nutrients, efficiency of energy and nitrogen utilization for milk production and N-balance have been presented in cows fed urea/molasses liquid diets and conventional diets.

    Full Text Available Interesterification becomes a very powerful tool in food industry. A blend of coconut oil and palm stearin is enzymatically interesterified by lipase (EC 3.1.1.3 in an aquarium reactor. The interesterified blend obtained is then incorporated in madeleines, mini croissants, and mini rolls. Physicochemical parameters’ assessment for molasses used is in good agreement with the international standards. Fatty acid composition of the interesterified blend and sugar content of molasses were assessed by gas chromatography (GC and high performance liquid chromatography (HPLC. A sensory evaluation of the madeleines, mini croissants, and buns has been carried out by untrained tasters, with a statistical analysis by a principal component analysis (PCA. Chromatographic characterization by Gas Chromatography revealed fatty acids, ranging from C6: 0 to C22: 0. Liquid sugar’s content by high performance liquid chromatography revealed three main sugars: sucrose, glucose, and fructose. Results of the sensory analysis showed the good quality of the prepared products.

    Full Text Available Kinetics of alcoholic fermentation by yeast Kluyveromyces marxianusZIM 75 in various media based on whey and molasses were monitored. The fermentations were performed under static and semiaerobic conditions at 34°C. Deproteinized whey and molasses were mixed in various proportions to give final sugar mass concentrations of 5%, 10% and 15% in medium. The experiments conducted showed that medium with 10 % of sugar (sucrose:lactose=1:1 is optimal for alcoholic fermentations in static and semiaerobic conditions. The best ethanol yield after 24 hours of fermentation was 4.05 % (V/V in static conditions and 4.9 % (V/V in semiaerobic conditions. The biomass yield was 7.78 g d.m./L in semiaerobic conditions and 3.19 g d.m./L in static conditions.

    The aim of this work was to develop an economical bioprocess to produce the bio-ethanol from soybean molasses at laboratory, pilot and industrial scales. A strain of Saccharomyces cerevisiae (LPB-SC) was selected and fermentation conditions were defined at the laboratory scale, which included the medium with soluble solids concentration of 30% (w/v), without pH adjustment or supplementation with the mineral sources. The kinetic parameters - ethanol productivity of 8.08g/Lh, YP/S 45.4%, YX/S 0.815%, m 0.27h(-1) and microX 0.0189h(-1) - were determined in a bench scale bioreactor. Ethanol production yields after the scale-up were satisfactory, with small decreases from 169.8L at the laboratory scale to 163.6 and 162.7L of absolute ethanol per ton of dry molasses, obtained at pilot and industrial scales, respectively.

    2014-11-28

    Co-digesting molasses wastewater and sewage sludge was evaluated for hydrogen production by response surface methodology (RSM). Batch experiments in accordance with various dilution ratios (40- to 5-fold) and waste mixing composition ratios (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100, on a volume basis) were conducted. Volatile solid (VS) concentration strongly affected the hydrogen production rate and yield compared with the waste mixing ratio. The specific hydrogen production rate was predicted to be optimal when the VS concentration ranged from 10 to 12 g/l at all the mixing ratios of molasses wastewater and sewage sludge. A hydrogen yield of over 50 ml H2/g VS(removed) was obtained from mixed waste of 10% sewage sludge and 10 g/l VS (about 10-fold dilution ratio). The optimal chemical oxygen demand/ total nitrogen ratio for co-digesting molasses wastewater and sewage sludge was between 250 and 300 with a hydrogen yield above 20 ml H2/g VS(removed).

    2008-11-01

    The fungus Mucor indicus is found in this study able to consume glucose and fructose, but not sucrose in fermentation of sugarcane and sugar beet molasses. This might be an advantage in industries which want to selectively remove glucose and fructose for crystallisation of sucrose present in the molasses. On the other hand, the fungus assimilated sucrose after hydrolysis by the enzyme invertase. The fungus efficiently grew on glucose and fructose and produced ethanol in synthetic media or from molasses. The cultivations were carried out aerobically and anaerobically, and manipulated toward filamentous or yeast-like morphology. Ethanol was the major metabolite in all the experiments. The ethanol yield in anaerobic cultivations was between 0.35 and 0.48 g/g sugars consumed, depending on the carbon source and the growth morphology, while a yield of as low as 0.16 g/g was obtained during aerobic cultivation. The yeast-like form of the fungus showed faster ethanol production with an average productivity of 0.90 g/l h from glucose, fructose and inverted sucrose, than the filamentous form with an average productivity of 0.33 g/l h. The biomass of the fungus was also analyzed with respect to alkali-insoluble material (AIM), chitin, and chitosan. The biomass of the fungus contained per g maximum 0.217 g AIM and 0.042 g chitosan in yeast-like cultivation under aerobic conditions.

    A new local strain of S. cerevisiae F-514, for ethanol production during hot summer season, using Egyptian sugar cane molasses was applied in Egyptian distillery factory. The inouluum was propagated through 300 L, 3 m(3), and 12 m(3) fermenters charged with diluted sugar cane molasses containing 4%-5% sugars. The yeast was applied in fermentation vessels 65 m(3) working volume to study the varying concentrations of urea, DAP, orthophosphoric acid (OPA), and its combinations as well as magnesium sulfate and inoculum size. The fermenter was allowed to stay for a period of 20 hours to give time for maximum conversion of sugars into ethanol. S. cerevisiae F-514 at molasses sugar level of 18% (w/v), inoculum size of 20% (v/v) cell concentration of 3.0 × 10(8)/mL, and combinations of urea, diammonium phosphate (DAP), orthophosphoric acid (OPA), and magnesium sulfate at amounts of 20, 10, 5, and 10 kg/65 m(3) working volume fermenters, respectively, supported maximum ethanol production (9.8%, v/v), fermentation efficiency (FE) 88.1%, and remaining sugars (RS) 1.22%. The fermentation resulted 13.4 g dry yeast/L contained 34.6% crude protein and 8.2% ash. By selecting higher ethanol yielding yeast strain and optimizing, the fermentation parameters both yield and economics of the fermentation process can be improved.

    This study was conducted to determine the effects of freezing and supplementation of molasses (M), lactic acid bacteria (LAB) and LAB+enzyme mixture on chemical and nutritional composition of sunflower silage (SF). Sunflower crops were harvested (at about 29.2%±1.2% dry matter) and half of fresh sunflower was ensiled alone and half was frozen (F) at −20°C for 7 days. Silage additives were admixed into frozen SF material. All samples were ensiled in glass jars with six replicates for 90 days. The treatments were as follows: i) positive control (non-frozen and no additives, NF), ii) negative control (frozen, no additives, F), iii) F+5% molasses (FM), iv) F+LAB (1.5 g/tons, Lactobacillus plantarum and Enterococcus faecium, FLAB); v) F+LAB+enzyme (2 g/tons Lactobacillus plantarum and Enterococcus faecium and cellulase and amylase enzymes, FLEN). Freezing silage increased dry matter, crude ash, neutral detergent fiber, and acid detergent lignin. The organic matter, total digestible nutrient, non-fiber carbohydrate, metabolizable energy and in vitro dry matter digestibility were negatively influenced by freezing treatments (pensiling may negatively affect silage quality, while molasses supplementation improved some quality traits of frozen silage. Lactic acid bacteria and LAB+enzyme inoculations did not effectively compensate the negative impacts of freezing on sunflower silage. PMID:26954197

    High-cell-density cultivation of yeast was investigated using the agricultural waste products corn steep liquor (CSL) and molasses. The Saccharomyces cerevisiae KV-25 cell mass was significantly dependent on the ratio between C and N sources. The concentrations of molasses and CSL in the culture medium were statistically optimized at 10.25% (v/v) and 16.87% (v/v), respectively, by response surface methodology (RSM). Batch culture in a 5-l stirred tank reactor using the optimized medium resulted in a cell mass production of 36.5 g/l. In the fed-batch culture, the feed phase was preceded by a batch phase using the optimized medium, and a very high dried-cell-mass yield of 187.63 g/l was successfully attained by feeding a mixture of 20% (v/v) molasses and 80% (v/v) CSL at a rate of 22 ml/h. In this system, the production of cell mass depended mainly on the agitation speed, the composition of the feed medium, and the glucose level in the medium, but only slightly on the aeration rate.

    Over the last decade the Swiss health care system has undergone several changes, resulting in stronger economic constraints, a heavier administrative workload and limited work autonomy for doctors. In this context we examined the change in burnout prevalence over time among Swiss doctors surveyed during this period. Cross-sectional survey data collected by mail in 2002, 2004 and 2007 throughout the country were used. Measures included the Maslach Burnout Inventory (MBI), several socio-demographics (gender, living alone, having children), and work-related characteristics (number of years in current workplace, hours worked). Answers to the MBI were used to classify respondents into moderate (high score on either the emotional exhaustion or the depersonalisation/cynicism subscale) and high degree of burnout (scores in the range of burnout in all three scales). Rates of moderate-degree burnout increased from 33% to 42% among general practitioners (p = 0.002) and from 19% to 34% among paediatricians (p = 0.001) (high degree of burnout: 4% to 6% [p = 0.17] and 2% to 4% [p = 0.42] respectively). After adjustment for significant socio-demographic and work-related characteristics, an increased risk of moderate burnout was found for doctors surveyed in 2004 and 2007 (OR 1.6, 95%CI 1.3 to 2.0), general practitioners (OR 1.6, 95%CI 1.3 to 2.0) and French-speaking doctors (OR 1.5, 95%CI 1.3 to 1.9). An increased risk of high-degree burnout was found only for general practitioners (OR 1.8, 95%CI 1.05 to 3.0). Burnout levels among Swiss doctors have increased over the last decade, in particular among French-speaking doctors.

    The Swiss Permanent Mission has informed CERN that the "attestations de fonctions" issued to certain members of the personnel and the "attestations" issued to their family members will gradually be replaced by P-type "cartes de légitimation" (see specimen copies in the printed Bulletin). This card’s name, together with its more contemporary design compared with old-style "Attestations" issued in the 1970s, will make the holder’s daily life much easier, e.g. when crossing borders, renting accommodation or setting up a telephone line. The Users Office (PH Department) and the Cards Office (HR Department), which are responsible for handling requests for "cartes de légitimation", will provide information in due course on how they intend to organise the exchange of "attestations" (priority will be given to residents of Switzerland, in particular those requiring a visa for the Schengen area).

    This article is a short version of the ENET number 210369. This report for the Swiss Federal Office of Energy (SFOE) describes a benchmarking pilot project carried out as a second phase in the development of a formula for the regulation of an open electricity market in Switzerland. It follows on from an initial phase involving the definition of a 'blue print' and a basic concept. The aims of the pilot project - to check out the practicability of the concept - are discussed. The collection of anonymised data for the benchmarking model from over 30 electricity utilities operating on all 7 Swiss grid levels and their integration in the three areas 'Technology', 'Grid Costs' and 'Capital Invested' are discussed in detail. In particular, confidentiality and data protection aspects are looked at. The methods used in the analysis of the data are described and the results of an efficiency analysis of various utilities are presented. The report is concluded with a listing of questions concerning data collection and analysis as well as operational and capital costs that are still to be answered

    2014-01-01

    This book tells the story of the Swiss Institute for Nuclear Research (SIN). The institute was founded in 1968 and became part of the Paul Scherrer Institute (PSI) in 1988. Its founding occurred at a time when physics was generally considered the key discipline for technological and social development. This step was unusual for a small country like Switzerland and showed courage and foresight. Equally unusual were the accomplishments of SIN, compared with similar institutes in the rest of the world, as well as its influence on Swiss, and partially also on international politics of science. That this story is now available in a widely understandable form is due to the efforts of some physicists, who took the initiative as long as contemporary witnesses could still be questioned. As is usually the case, official documents always show just an excerpt of what really happened. An intimate portrayal of people who contributed to success requires personal memories. This text relies on both sources. In addition, the e...

    During the nine months of pregnancy, women have to regularly visit several physicians for continuous monitoring of the health and development of the fetus and mother. Comprehensive examination results of different types are generated in this process; documentation and data transmission standards are still unavailable or not in use. Relevant information is collected in a paper-based maternity record carried by the pregnant women. To improve availability and transmission of data, we aim at developing a first prototype for an electronic maternity record for Switzerland. By analyzing the documentation workflow during pregnancy, we determined a maternity record data set. Further, we collected requirements towards a digital maternity record. As data exchange format, the Swiss specific exchange format SMEEX (swiss medical data exchange) was exploited. Feedback from 27 potential users was collected to identify further improvements. The relevant data is extracted from the primary care information system as SMEEX file, stored in a database and made available in a web and a mobile application, developed as prototypes of an electronic maternity record. The user confirmed the usefulness of the system and provided multiple suggestions for an extension. An electronical maternity record as developed in this work could be in future linked to the electronic patient record.

    Pigments in molasses wastewater (MWW) effluent, such as melanoidins, were considered as kinds of the most recalcitrant and hazardous colorant contaminants to the environment. In this study, de-coloring the MWW by a synergistic combination of micro-electrolysis with bio-treatment was performed. Aiming to a high de-colorization yield, levels of nutrition source supplies, MWW dilution ratio, and micro-electrolysis reaction time were optimized accordingly. For a diluted (50 %, v/v) MWW, an maximum overall de-colorization yield (97.1 ± 0.5 %, for absorbance at 475 nm) was achieved through the bio-electrolysis treatment. In electrolysis bio-treatment, the positive effect of micro-electrolysis was also revealed by a promoted growth of fungal biomass as well as activities of ligninolytic enzymes. Activities of lignin peroxidase, manganese peroxidase, and laccase were promoted by 111.2, 103.9, and 7.7 %, respectively. This study also implied that the bio-treatment and the micro-electrolysis had different efficiencies on removal of pigments with distinct polarities.

    Fifteen bacterial strains isolated from molasses grass (Melinis minutiflora Beauv.) were identified as nitrogen-fixers by using the acetylene-reduction assay and PCR amplification of nifH gene fragments. These strains were classified as a unique group by insertion sequence-PCR fingerprinting, SDS-PAGE protein patterns, DNA-DNA hybridization, 16S rRNA gene sequencing and morphological characterization. Phylogenetic analysis of the 16S rRNA gene indicated that these diazotrophic strains belonged to the genus Azospirillum and were closely related to Azospirillum lipoferum (with 97.5 % similarity). In all the analyses, including in addition phenotypic characterization using Biolog MicroPlates and comparison of cellular fatty acids, this novel group was found to be different from the most closely related species, Azospirillum lipoferum. Based on these data, a novel species, Azospirillum melinis sp. nov., is proposed for these endophytic diazotrophs of M. minutiflora, with TMCY 0552(T) (=CCBAU 5106001(T) = LMG 23364(T) = CGMCC 1.5340(T)) as the type strain.

In yoghurt samples, physical-chemical properties, texture, color and sensory analysis were determined on the 1st, 5th, 10th and 14th days of storage, while total phenolics (TF levels were determined on the 14th, 24th, 32nd, 48th, 72nd, 120th, 240th and 336th hours of storage. In all samples during storage, hardness and viscosity increased along with the acidity increase, although the increases in YTSM and YTSMC were lower than in YTSMX. In YTSMX, in spite of the increase in acidity after the 1st day, serum separation was very low while viscosity and hardness values were higher compared to the other samples. YTSMX was found to be superior to the other samples in terms of physicochemical, textural, microbiological and sensory properties. Total phenolic contents and L*a*b* levels increased in all samples throughout storage, the highest values of which were in YTSMX. After the 5th day of the storage, Lactobacillus delbrueckii subsp. bulgaricus became the dominant microbial flora. After the 5th day of storage, Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus levels were highest in YTSMX.

    Full Text Available Comparative studies on the growth of Micrococcus varians were carried out in BHI culture medium (control as well as in a culture medium with 2% diluted sugar cane blackstrap molasses, enriched with 0.1% yeast extract. The experiment was conducted with three samples of the experimental and control media in a 5 liter fermentor with working volume of 3.5 liters, continuous agitation (150 rpm, 35 ± 0.1°C temperature, 0.7 L air. l-1 medium. min -1, initial pH 7.0 ± 0.2, 24 hour fermentation period, and approximate inoculum of 6.0 log10 CFU/ml. Samples were collected at 2-hour intervals. Micrococcus varians grew in the two culture media studied, which confirms the experimental medium viability for the growth of this species. The final average concentration of biomass was higher in the control medium than in the experimental medium: 0.99 g.l-1 and 0.78 g.l-1, respectively. The final number of viable cells at the end of fermentation was 20.65 log10 CFU/ml for the control medium (BHI, while in the experimental medium the number of viable cells was 19.43 log10 CFU/ml. The consumption of total sugars was higher for the biomass in the control medium (79.78%, while only 50.53% was consumed for the experimental medium.

    Fructo- (FOS) and galacto-oligosaccharides have been used to promote the growth of probiotics, mainly those from Lactobacillus genus. However, only few reports have evaluated the effect of prebiotics on bacteriocins activity and production. In this work, we characterized the effect of FOS supplementation on the growth, lactic and acetic acids production, and antimicrobial activity of crude extracts obtained from Lactobacillus strains isolated from ensiled corn and molasses. Seven out of 28 isolated Lactobacillus, belonging to Lactobacillus casei, Lactobacillus plantarum, and Lactobacillus brevis, showed antimicrobial activity against Listeria innocua. Among them, the strain L. plantarum LE5 showed antimicrobial activity against Listeria monocytogenes and Enteroccocus faecalis; while the L. plantarum LE27 strain showed antimicrobial effect against L. monocytogenes, E. faecalis, Escherichia coli and Salmonella enteritidis. This antimicrobial activity in most of the cases was obtained only after FOS supplementation. In summary, these results show the feasibility to increase the antimicrobial activity of Lactobacillus bacteriocins by supplementing the growth medium with FOS. Copyright © 2012 Elsevier Ltd.

    Full Text Available The aim of this work was to improve the quality of gluten-free bread made with high content of soy flour and enriched with sugar beet molasses by incorporating ingredients with a potential to simultaneously enhance the nutritional quality of the breads. The following ingredients were used: pea protein isolate, pea fibre and chia seeds. The chosen ingredients exerted positive effects on bread quality. They promoted volume increase and crumb softening. In this respect, the most effective ingredients were pea protein isolate (at 1% supplementation level, pea fibre (at up to 2% supplementation level and chia seeds (at 1% supplementation level. The sensory analysis revealed that pea fibre and chia addition at 1 and 2% supplementation level provided bread with higher scores regarding overall acceptance, crumb texture and taste. At 1% supplementation level, there was not found statistically significant difference in sensory attributes of bread supplemented with pea protein isolate in comparison to the control. However, pea protein isolate was found to strongly diminish bread taste at 4% supplementation level due to presence of beany taste.

    An anaerobic continuous-flow hydrogen fermentor was operated at a hydraulic retention time of 8 h using condensed molasses fermentation solubles (CMS) substrate of 40 g-COD/L. Serum bottles were used for seed micro-flora cultivation and batch hydrogen fermentation tests (CMS substrate concentrations of 10-160 g-COD/L). Three hydrogen-producing bacterial strains Clostridium sporosphaeroides F52, Clostridium tyrobutyricum F4 and Clostridium pasteurianum F40 were isolated from the seed fermentor and used as the seeding microbes in single and mixed-culture cultivations for determining their hydrogen productivity. These strains possessed specific hydrogenase genes that could be detected from CMS-fed hydrogen fermentors and were major hydrogen producers. C. pasteurianum F40 was the dominant strain with a high hydrogen production rate while C. sporosphaeroides F52 may play a main role in degrading carbohydrate and glutamate. These strains could be co-cultivated as a symbiotic mixed-culture process to enhance hydrogen productivity. C. pasteurianum F40 or C. tyrobutyricum F4 co-culture with the glutamate-utilizing strain C. sporosphaeroides F52 efficiently enhanced hydrogen production by 12-220% depending on the substrate CMS concentrations.

    2008-01-01

    In the context of the world's energy crisis and environmental concerns, crop-based ethanol has emerged as an energy alternative, the use of which can help reduce oil imports as well as emissions of CO 2 and other air pollutants. However, a clear disadvantage of ethanol is its high cost over gasoline under the current pricing scheme that does not include externalities. The intent of this study is to perform a life cycle analysis comparing environmental and cost performance of molasses-based E10 with those of CG. The results show that although E10 provides reduction in fossil energy use, petroleum use, CO 2 and NO x emissions, its total social costs are higher than those of gasoline due to higher direct production costs and external costs for other air emissions, e.g. CH 4 , N 2 O, CO, SO 2 , VOC and PM 10 . An analysis of projection scenarios shows that technological innovations towards cleaner production help maximize ethanol's benefits whilst minimizing its limitations

    Full Text Available Three polyphenols were isolated and purified from sugar beet molasses by ultrasonic-aid extraction and various chromatographic techniques, and their structures were elucidated by spectral analysis. Cytotoxicity and the molecular mechanism were measured by methyl thiazolyl tetrazolium (MTT assay, flow cytometry, caspase-3 activity assay and Western blot assay. The results showed that gallic acid, cyanidin-3-O-glucoside chloride and epicatechin have cytotoxicity to the human colon, hepatocellular and breast cancer cells. Cyanidin-3-O-glucoside chloride showed its cytotoxicity against various tumor cell lines, particularly against colon cancer Caco-2 cells with half maximal inhibitory concentration (IC50 value of 23.21 ± 0.14 μg/mL in vitro. Cyanidin-3-O-glucoside chloride may be a potential candidate for the treatment of colon cancer. In the mechanism study, cyanidin-3-O-glucoside chloride increased the ratio of cell cycle at G0/G1 phase and reduced cyclin D1 expression on Caco-2 cells. Cyanidin-3-O-glucoside chloride decreased mutant p21 expression, and increased the ratio of Bax/Bcl-2 and the activation of caspase-3 to induce apoptosis.

  15. Swiss Re Global Flood Hazard Zones: Know your flood risk

    2012-12-01

    Floods, among all natural disasters, have a great damage potential. On a global basis, there is strong evidence of increase in the number of people affected and economic losses due to floods. For example, global insured flood losses have increased by 12% every year since 1970 and this is expected to further increase with growing exposure in the high risk areas close to rivers and coastlines. Recently, the insurance industry has been surprised by the large extent of losses, because most countries lack reliable hazard information. One example has been the 2011 Thailand floods where millions of people were affected and the total economic losses were 30 billion USD. In order to assess the flood risk across different regions and countries, the flood team at Swiss Re based on a Geomorphologic Regression approach, developed in house and patented, produced global maps of flood zones. Input data for the study was obtained from NASA's Shuttle Radar Topographic Mission (SRTM) elevation data, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) and HydroSHEDS. The underlying assumptions of the approach are that naturally flowing rivers shape their channel and flood plain according to basin inherent forces and characteristics and that the flood water extent strongly depends on the shape of the flood plain. On the basis of the catchment characteristics, the model finally calculates the probability of a location to be flooded or not for a defined return period, which in the current study was set to 100 years. The data is produced at a 90-m resolution for latitudes 60S to 60N. This global product is now used in the insurance industry to inspect, inform and/or insure the flood risk across the world.

    Glauconite investigations: the main problem in dating glauconites lies in the identification of authigenic minerals which have not been influenced by post-sedimentary processes. The age determination on glauconites from the three different tectonic units: the Jura mountains, the molasse basin and the Helvetic nappes, yield inconsistent results. Up to 35% too young K-Ar ''ages'' of glauconites from limestones from the Helvetic nappes can be traced to partial Ar loss caused by sediment-lithification and tectonic events. Sr-isotope stratigraphy: multiple analyses of recent samples from the Mediterranean Sea and from the North Atlantic show that the 87 Sr/ 86 Sr isotope ratios correspond well. In a stratigraphic ideal section from the Upper marine molasse a resolution of 206 Pb/ 238 U method zircons from the Fish Canyon Tuff were measured and yielded ages of 28.49±0.10, 24.46±0.11 and 28.46±0.13 Ma. These values correspond well with the published mean value of zircon and apatite fission track age of 28.4±0.7 Ma. Thus, the U-Pb method for dating young volcanic minerals seems to be suitable. However, the published mean value (''solid state age'') of Naeser et al. (1981) is higher than the published (''gas age'') mean value of 27.2±0.7 Ma based on biotite, sanidine, hornblende and plagioclase. (author) figs., tabs., refs

    Simultaneous production of hydrogen and methane in two sequential stages of acidogenic and methanogenic step was investigated in two serial operated up-flow anaerobic sludge bed (UASB) reactors at thermophilic temperature (55 deg C). Hydrogen production from molasses was carried out in the first reactor at the hydraulic retention time (HRT) of 1 day. Molasses were converted into hydrogen with the yield of 1.3 mole-H{sub 2}/mole-hexose{sub added} or 82.7 ml- H{sub 2}/g-VS{sub added} of molasses, and the hydrogen productivity was 2696 ml-H{sub 2}/dxl{sub reactor}. The effluent (mainly butyrate, acetate and lactate) after the acidogenic process was subsequently fed to the second reactor for methane production at HRT of 3 days. Methane production yield of 255 ml-H{sub 2}/g-VS{sub added} of influent or 130.1 ml-H{sub 2}/g-VS{sub added} of molasses and methane production rate of 1056 ml/dxl{sub reactor} were obtained. Significant decrease of volatile fatty acids (VFAs) was also observed in the effluent of the second reactor. A two phase anaerobic digestion was successfully demonstrated for molasses as a potential substrate to produce hydrogen and subsequent methane in the UASB reactors

  18. Co-digestion of molasses or kitchen waste with high-rate activated sludge results in a diverse microbial community with stable methane production.

    Kitchen waste and molasses are organic waste streams with high organic content, and therefore are interesting substrates for renewable energy production by means of anaerobic digestion. Both substrates, however, often cause inhibition of the anaerobic digestion process, when treated separately, hence, co-digestion with other substrates is required to ensure stable methane production. In this research, A-sludge (sludge harvested from a high rate activated sludge system) was used to stabilize co-digestion with kitchen waste or molasses. Lab-scale digesters were fed with A-sludge and kitchen waste or molasses for a total period of 105 days. Increased methane production values revealed a stabilizing effect of concentrated A-sludge on kitchen waste digestion. Co-digestion of molasses with A-sludge also resulted in a higher methane production. Volumetric methane production rates up to 1.53 L L(-1) d(-1) for kitchen waste and 1.01 L L(-1) d(-1) for molasses were obtained by co-digestion with A-sludge. The stabilizing effect of A-sludge was attributed to its capacity to supplement various nutrients. Microbial community results demonstrated that both reactor conditions and substrate composition determined the nature of the bacterial community, although there was no direct influence of micro-organisms in the substrate itself, while the methanogenic community profile remained constant as long as optimal conditions were maintained.

    2010-07-01

    This comprehensive report issued by the Paul Scherrer Institute (PSI) in Switzerland takes a look at the design concepts behind the institute's SwissFEL X-ray Laser facility - in particular concerning the conceptual design of the injector system. The SwissFEL X-ray FEL project at PSI, involves the development of an injector complex that enables operation of a FEL system operating at 0.1 - 7 nm with permanent-magnet undulator technology and minimum beam energy. The injector pre-project was motivated by the challenging electron beam requirements necessary to drive the SwissFEL accelerator facility. The report takes a look at the mission of the test facility and its performance goals. The accelerator layout and the electron source are described, as are the low-level radio-frequency power systems and the synchronisation concept. The general strategy for beam diagnostics is introduced. Low energy electron beam diagnostics, the linear accelerator (Linac) and bunch compressor diagnostics are discussed, as are high-energy electron beam diagnostics. Wavelength selection for the laser system and UV pulse shaping are discussed. The laser room for the SwissFEL Injector and constructional concepts such as the girder system and alignment concepts involved are looked at. A further chapter deals with beam dynamics, simulated performance and injector optimisation. The facility's commissioning and operation program is examined, as are operating regimes, software applications and data storage. The control system structure and architecture is discussed and special subsystems are described. Radiation safety, protection systems and shielding calculations are presented and the lateral shielding of the silo roof examined

    There is extensive evidence that social identities can shape people’s attitudes and behavior, but what about sensory judgments? We examined the possibility that social identity concerns may also shape the judgment of non-social properties—namely, olfactory judgment. In two experiments, we presented Swiss and non-Swiss participants with the odor of chocolate, for which Switzerland is world-famous, and a control odor (popcorn). Swiss participants primed with Swiss identity reported the odor of chocolate (but not popcorn) as more intense than non-Swiss participants (Experiments 1 and 2) and than Swiss participants primed with individual identity or not primed (Experiment 2). The self-reported intensity of chocolate smell tended to increase as identity accessibility increased—but only among Swiss participants (Experiment 1). These results suggest that identity priming can counter-act classic sensory habituation effects, allowing identity-relevant smells to maintain their intensity after repeated presentations. This suggests that social identity dynamically influences sensory judgment. We discuss the potential implications for models of social identity and chemosensory perception. PMID:27725715

    The Swiss Permanent Mission has informed CERN that the "attestations de fonctions" issued to certain members of the personnel and the "attestations" issued to their family members will gradually be replaced by P-type "cartes de légitimation" (see specimen copies below). This card’s name, together with its more contemporary design compared with old-style "Attestations" issued in the 1970s, will make the holder’s daily life much easier, e.g. when crossing borders, renting accommodation or setting up a telephone line. The Users Office (PH Department) and the Cards Office (HR Department), which are responsible for handling requests for "cartes de légitimation", will provide information in due course on how they intend to organise the exchange of "attestations" (priority will be given to residents of Switzerland, in parti...

    Since 1985, geothermal R and D has evolved steadily in Switzerland. REgional low-enthalphy exploration and resource assessment are largely complete; emphasis is now on drilling and development. Vertical earth-heat exchangers (small-scale, decentralized, heat pump-coupled heating facilities) increase rapidly in number; the governmental system of risk coverage for geothermal drilling, established in 1987, gives rise to several drilling projects. Of these, a single well and a doublet have been successfully completed so far. Numerical modeling of coupled thermohydraulic processes in fracture-dominate Hot Dry Rock systems including rock-mechanics aspects, is in progress. In this paper some further efforts such as contributions to general geothermics, exploration and resource assessment activities in Switzerland, and financing of geothermal development abroad by Swiss banks are described

  4. The ``Swiss cheese'' instability of bacterial biofilms

    2012-11-01

    Bacteria often adhere to surfaces, where they develop polymer-encased communities (biofilms) that display dramatic resistance to antibiotic treatment. A better understanding of cell detachment from biofilms may lead to novel strategies for biofilm disruption. Here we describe a new detachment mode, whereby a biofilm develops a nearly regular array of ~50-100 μm holes. Using surface-treated microfluidic devices, we create biofilms of controlled shape and size. After the passage of an air plug, the break-up of the residual thin liquid film scrapes and rearranges bacteria on the surface, such that a ``Swiss cheese'' pattern is left in the residual biofilm. Fluorescent staining of the polymeric matrix (EPS) reveals that resistance to cell dislodgement correlates with local biofilm age, early settlers having had more time to hunker down. Because few survivors suffice to regrow a biofilm, these results point at the importance of considering microscale heterogeneity in assessing the effectiveness of biofilm removal strategies.

    We present a phenomenological model which we show can be obtained as a local realization of large volume D 3 / D 7 μ-Split SUSY on a nearly special Lagrangian three-cycle embedded in the big divisor of a Swiss-Cheese Calabi-Yau [Mansi Dhuria, Aalok Misra, arxiv:arXiv:1207.2774 [hep-ph], Nucl. Phys. B867 (2013) 636-748]. After identification of the first generation of SM leptons and quarks with fermionic super-partners of four Wilson line moduli, we discuss the identification of gravitino as a potential dark matter candidate. We also show that it is possible to obtain a 125 GeV light Higgs in our setup.

    Hydrogen production from diluted molasses by anaerobic fermentation bacteria was investigated in a three-compartment anaerobic baffled reactor (ABR) with an effective volume of 27.48 L. After being inoculated with aerobic activated sludge and operated at chemical oxygen demand (COD) of 5000 mg/L and temperature of 35 C for 26 days, the ABR achieved stable ethanol-type fermentation. The liquid fermentation products, including volatile fatty acids (VFAs) and ethanol, stabilized at 1254, 2053, and 2761 mg/L in the three compartments, respectively. Effluent pH, oxidation-reduction potential (ORP), and alkalinity ranged at 4.3-4.4, -241 to -249mV, and 306-334mgCaCO{sub 3}/L, respectively. The hydrogen yield of the ABR was 32.51 L/d at the stable operation status, specific hydrogen production rate of anaerobic activated sludge was 0.13 L/g MLVSS d, and the substrate conversion rate was 0.13 L/g COD. Hydrogen yields, fermentation types, and acclimatization durations varied in each compartment, with the 1st compartment having lowest hydrogen yield but longest acclimatization duration and the 2nd and 3rd compartments having higher hydrogen yields but shorter acclimatization durations. The study found that the individual compartment configuration in the ABR system provided a favorable environment for different types of anaerobic bacteria. Compared with complete stirring tank reactor (CSTR), the ABR system had a better operation stability and microbial activity, which led to higher substrate conversion rate and hydrogen production ability.

    Full Text Available The influence of feeding urea-molasses blocks (UMB on growth and gastrointestinal (GI nematode parasitism of weaner goats grazing the same pasture was investigated on a farm in Nyandarua District, Kenya. Thirty female Small East African goat kids at an average age of 5 months were initially treated with albendazole orally (5 mg kg-1 body mass and randomly assigned into one of two groups: group I were fed UMB prepared using a cold process and group II kids (controls received no block supplementation (NBS. The UMB were given in the evening when the animals returned from grazing and were consumed during the night at a rate of 95.0 g head-1 day-1. Supplementation was undertaken for 3 consecutive months from July to September 2001 and January to March 2002. Body mass of the kids and faecal egg counts were measured monthly and larval cultures were performed on positive faecal samples of kids of each group. Five goats from each group were randomly selected for slaughter and total counts and identification of worms at the end of June 2002. Significant differences (P < 0.05 were found in cumulative mass gains of kids in group I from September compared with those in group II. On termination of the study kids in group I had gained an average of (+ SD 20.4 ± 1.4 kg while those in group II had gained 11.8 + 1.1 kg. From January 2002, faecal egg counts of the kids in the UMB group differed significantly (P < 0.05 from those of the NBS group and at slaughter, the mean (+ SD worm counts for the UMB group was 482 + 299 while that of the NBS group was 1 302 + 410. In all the goats, Haemonchus contortus was the predominant nematode recovered. These results indicate that UMB had significant effects in the control of GI nematode parasitism and enhanced growth of the young goats.

    L-Lysine is an essential amino acid that can be produced by chemical processes from fossil raw materials, as well as by microbial fermentation, the latter being a more efficient and environmentally friendly procedure. In this work, the production process of L-lysine-HCl is studied using a systematic approach based on modeling and simulation, which supports decision making in the early stage of process design. The study considers two analysis stages: first, the dynamic analysis of the fermentation reactor, where the conversion of sugars from sugarcane molasses to L-lysine with a strain of Corynebacterium glutamicum is carried out. In this stage, the operation mode (either batch or fed batch) and operating conditions of the fermentation reactor are defined to reach the maximum technical criteria. Afterwards, the second analysis stage relates to the industrial production process of L-lysine-HCl, where the fermentation reactor, upstream processing, and downstream processing are included. In this stage, the influence of key parameters on the overall process performance is scrutinized through the evaluation of several technical, economic, and environmental criteria, to determine a profitable and sustainable design of the L-lysine production process. The main results show how the operating conditions, process design, and selection of evaluation criteria can influence in the conceptual design. The best plant design shows maximum product yield (0.31 g L-lysine/g glucose) and productivity (1.99 g/L/h), achieving 26.5% return on investment (ROI) with a payback period (PBP) of 3.8 years, decreasing water and energy consumption, and with a low potential environmental impact (PEI) index.

    We studied silage fermentation of kudzu (KZ), sugarcane top (ST) and their mixtures treated with additives to be able to effectively use available local feed resources. The silages were prepared using KZ, ST, KZ 90% + ST 10%, KZ 80% + ST 20%, KZ 70% + ST 30% and KZ 60% + ST 40%, based on fresh matter (FM). These silages were treated with 10 8  colony-forming units/g epiphytic lactic acid bacteria (LAB), 5% molasses and 0.02% cellulase of FM. The KZ contained higher crude protein (CP; 14.52%) content and lower levels of neutral detergent fiber (NDF; 62.15%) than those of ST (6.84% CP and 64.93% NDF) based on dry matter (DM). The KZ 60% + ST 40% silage fermented well with a higher (P < 0.05) lactic acid content and lower (P < 0.05) pH than those of the other mixed silages. Silages treated with molasses had lower (P < 0.05) ammonia-N, NDF, acid detergent fiber, and hemi-cellulose contents as well as pH, but higher (P < 0.05) DM, water-soluble carbohydrate, and lactic acid contents, than those of the control, LAB and cellulase treatments. The results confirmed that KZ 60% + ST 40% was the best mixing ratio to prepare silage, and molasses improved silage fermentation and fiber degradation. © 2017 Japanese Society of Animal Science.

    Anaerobic digestion is a complex process involving hydrolysis, acidogenesis, acetogenesis and methanogenesis. The separation of the hydrogen-yielding (dark fermentation) and methane-yielding steps under controlled conditions permits the production of hydrogen and methane from biomass. The characterization of microbial communities developed in bioreactors is crucial for the understanding and optimization of fermentation processes. Previously we developed an effective system for hydrogen production based on long-term continuous microbial cultures grown on sugar beet molasses. Here, the acidic effluent from molasses fermentation was used as the substrate for methanogenesis in an upflow anaerobic sludge blanket bioreactor. This study focused on the molecular analysis of the methane-yielding community processing the non-gaseous products of molasses fermentation. The substrate for methanogenesis produces conditions that favor the hydrogenotrophic pathway of methane synthesis. Methane production results from syntrophic metabolism whose key process is hydrogen transfer between bacteria and methanogenic Archaea. High-throughput 454 pyrosequencing of total DNA isolated from the methanogenic microbial community and bioinformatic sequence analysis revealed that the domain Bacteria was dominated by Firmicutes (mainly Clostridia), Bacteroidetes, δ- and γ-Proteobacteria, Cloacimonetes and Spirochaetes. In the domain Archaea, the order Methanomicrobiales was predominant, with Methanoculleus as the most abundant genus. The second and third most abundant members of the Archaeal community were representatives of the Methanomassiliicoccales and the Methanosarcinales. Analysis of the methanogenic sludge by scanning electron microscopy with Energy Dispersive X-ray Spectroscopy and X-ray diffraction showed that it was composed of small highly heterogeneous mineral-rich granules. Mineral components of methanogenic granules probably modulate syntrophic metabolism and methanogenic

    Utilizing cane molasses as substrate, semi-pilot scale production of citric acid was investigated in fermentation trays (40 x 35 cm) with several gamma-ray induced mutants of Aspergillus niger. Of the mutants tested, two were found to have high yield efficiency (14/20, 51.06%; 79/20, 50.35%) of sugar to citric acid. The yield of other mutants (HB3, 10/20, 164/20, 277/30 and 112/40) ranged between 30 to 42%. The prospect of utilizing the high yielding mutants for commercial production of citric acid has been discussed. (author)

    The discoloration of a biologically pretreated waste water stream from a molasses processing by ozonation and two advanced oxidation processes (O 3 /H 2 O 2 and O 3 /γ-irradiation, respectively) was studied. Colour removal occurred with all three processes with almost the same efficiency. The main difference of the methods applied was reflected by the BOD increase during the discoloration period. By ozonation it was much higher than by AOPs but it also appeared with AOPs. AOPs were, therefore, not apt for an effective BOD control during discoloration. (authors)

    SWISS-MODEL Repository (http://swissmodel.expasy.org/repository/) is a database of 3D protein structure models generated by the SWISS-MODEL homology-modelling pipeline. The aim of the SWISS-MODEL Repository is to provide access to an up-to-date collection of annotated 3D protein models generated by automated homology modelling for all sequences in Swiss-Prot and for relevant models organisms. Regular updates ensure that target coverage is complete, that models are built using the most recent sequence and template structure databases, and that improvements in the underlying modelling pipeline are fully utilised. As of September 2008, the database contains 3.4 million entries for 2.7 million different protein sequences from the UniProt database. SWISS-MODEL Repository allows the users to assess the quality of the models in the database, search for alternative template structures, and to build models interactively via SWISS-MODEL Workspace (http://swissmodel.expasy.org/workspace/). Annotation of models with functional information and cross-linking with other databases such as the Protein Model Portal (http://www.proteinmodelportal.org) of the PSI Structural Genomics Knowledge Base facilitates the navigation between protein sequence and structure resources.

  5. Digital Preservation at the Swiss Federal Archives

    International Nuclear Information System (INIS)

    Ohnesorge, Krystyna

    2012-01-01

    The Swiss Federal Archives (SFA) archives Swiss government data when it is no longer in use. The SFA is responsible for advising, inspecting and issuing directives in records management and archiving services in offices, agencies and institutions subjected to the Federal Act on Archiving; as well as archiving and disseminating records and data of archival value. With regard to RWM, it thus in fact is an additional regulator. The conceptual basis for digital archiving at the SFA is based on the ISO OAIS Open Archival Information System Reference Model (ISO 14721:2003). The SFA use a process-orientated approach. The SFA and the Federal Office decide jointly which documents and data are to be archived. Archive-worthy documents and data are selected on the basis of a systematic appraisal. Wherever possible this should be carried out pro-actively - before the documents are actually created - based on an indexing or classification system. If there is clarity, people will know what data - and metadata - to keep for the submission. The submission is split into several stages, from appraisal to the conclusion of the submission. Information is never changed once it is archived, except that it carries out conservation measures. New information is a new submission.

    Abstract Rationale, aims and objectives Safety climate measurements are a broadly used element of improvement initiatives. In order to provide a sound and easy‐to‐administer instrument for the use in Swiss hospitals, we translated the Safety Climate Survey into German and French. Methods After translating the Safety Climate Survey into French and German, a cross‐sectional survey study was conducted with health care professionals (HCPs) in operating room (OR) teams and on OR‐related wards in 10 Swiss hospitals. Validity of the instrument was examined by means of Cronbach's alpha and missing rates of the single items. Item‐descriptive statistics group differences and percentage of ‘problematic responses’ (PPR) were calculated. Results 3153 HCPs completed the survey (response rate: 63.4%). 1308 individuals were excluded from the analyses because of a profession other than doctor or nurse or invalid answers (n = 1845; nurses = 1321, doctors = 523). Internal consistency of the translated Safety Climate Survey was good (Cronbach's alpha G erman = 0.86; Cronbach's alpha F rench = 0.84). Missing rates at item level were rather low (0.23–4.3%). We found significant group differences in safety climate values regarding profession, managerial function, work area and time spent in direct patient care. At item level, 14 out of 21 items showed a PPR higher than 10%. Conclusions Results indicate that the French and German translations of the Safety Climate Survey might be a useful measurement instrument for safety climate in Swiss hospital units. Analyses at item level allow for differentiating facets of safety climate into more positive and critical safety climate aspects. PMID:25656302

    The objective was to study effects of lactic acid bacteria (L) and molasses (M) on the microbial community and fermentation quality of soybean silage. Soybean was ensiled with no additive control (C), 0.5% molasses (0.5%M), 0.5%M+L (0.5%ML), 2%M, 2%M+L (2%ML) for 7, 14, 30 and 60days. The M-treated silages could increase the content of lactic acid and decrease butyric acid than control. Besides, higher crude protein was also observed in M-treated silages. With prolonged ensiling time, there was a reduction of the ratio of lactic acid/acetic acid in the 2%M-treated and 2%ML-treated silages. The combined addition of L and 2%M could enhance the account of desirable Lactobacillus and inhibit the growth of undesirable microorganism such as Clostridia and Enterobacter. In summary, the silage quality of soybean was improved with the addition of L and M. Copyright © 2017 Elsevier Ltd. All rights reserved.

    In this study, mesophilic biohydrogen production by a mixed culture, obtained from a continuous anaerobic reactor treating molasses effluent from sugarcane bagasse, was improved by using granular activated carbon (GAC) as the carrier material. A series of batch fermentation were performed at 37°C by feeding the anaerobic sludge bacteria with molasses to determine the effect of initial pH in the range of 5.5 to 7.5, and the effect of repeated batch cultivation on biohydrogen production. The enrichment of granular activated carbon (GAC) immobilised cells from the repeated batch cultivation were used as immobilised seed culture to obtain the optimal initial pH. The cumulative hydrogen production results from the optimal pH were fitted into modified Gompertz equation in order to obtained the batch profile of biohydrogen production. The optimal hydrogen production was obtained at an initial pH of 5.5 with the maximum hydrogen production (Hm) was found to be 84.14 ml, and maximum hydrogen production rate (Rm) was 3.63 mL/h with hydrogen concentration of 759 ppm. The results showed that the granular activated carbon was successfully enhanced the biohydrogen production by stabilizing the pH and therefore could be used as a carrier material for fermentative hydrogen production using industrial effluent.

    Full Text Available The applicability of Peleg equation was examined for the description of mass transfer during osmotic dehydration (OD of apple in sugar beet molasses. Mass transfer was investigated in terms of water loss (WL and solid gain (SG, during OD in 40-80% sugar beet molasses solutions, at 45, 55 and 65ºC. High regression coefficients obtained for Peleg constants (R2>0.975 indicate good fit to the experimental data. The Peleg rate constant varied from 0.144 to 0.785 (g/g i.s.w. and from 2.006 to 4.436 (g/g i.s.w. for WL and SG, respectively. The Peleg capacity constant varied from 1.142 to 1.553 (h g/g i.s.w. and from 8.254 to 11.930 (h g/g i.s.w. for WL and SG, respectively. The equilibrium WL∞ and SG∞ were estimated using the Peleg model. In addition, the activation energy (Ea for WL and SG was determined from the relationship between the Peleg rate constant and Arrhenius equation.

    The production of rum consists of fermentation, distillation, and aging. To check the influence of each step on the final rum aroma, molasses, mash, distillate, and the final rum were analyzed using the sensomics concept. The changes in key aroma compounds were determined by application of aroma extract dilution analysis (AEDA) in combination with gas chromatography-mass spectrometry for identification and by stable isotope dilution assays (SIDAs) for quantitation. Odor activity values (OAVs; ratio of concentration to respective odor threshold) were calculated for the compounds determined in the rum and, finally, the rum aroma was successfully simulated by recombination. (E)-β-Damascenone showed by far the highest OAV (3280) in rum. Although this compound was determined already in molasses, its concentration increased significantly during distillation, indicating a thermolabile precursor. Vanillin, 4-ethylphenol, 2-methoxyphenol, 4-ethyl-2-methoxyphenol, and 2-methoxy-4-propylphenol are well-known compounds mainly stemming from the wood barrels used for aging and showed an OAV ≥ 1. Another important group of aroma-active compounds in rum were ethyl esters, for which a significant increase was determined during fermentation but also to a lesser extent during aging. Altogether, the concentrations of 68% of the aroma-active compounds increased during the process, demonstrating its influence on the overall rum aroma.

    The study was carried out to evaluate the influence of urea plus molasses-treated wheat straw (WS) ensiled with cattle manure (CM) on nutrients intake, their digestibilities, and growth performance of crossbred (Sahiwal × Holstein Friesian) cattle calves. The CM was mixed with ground WS in a ratio of 30:70 on dry matter (DM) basis. The WS-CM mixture treated with urea (4% DM) and molasses (4% DM) was allowed to ferment for 40 days in a cemented pit. Four iso-nitrogenous and iso-energetic fermented wheat straw (FWS)-based experimental diets were formulated. The FWS0, FWS20, FWS30, and FWS40 diets contained 0%, 20%, 30%, and 40% FWS, respectively. Twenty calves (9-10 months of age) were randomly allocated to four dietary treatments in a randomized complete block design, five in each group. Increasing trends for DM, organic matter, crude protein, and neutral detergent fiber intakes by calves were observed with increasing dietary FWS level. Weight gain was significantly different among calves fed different levels of FWS. The highest weight gain (491.8 g/day) was observed in calves fed FWS40 diet, while calves fed FWS0 and FWS20 diets gained 350.0 and 449.6 g/day, respectively. The results from this study imply that the FWS can be added up to 30% in the diet of growing crossbred calves without any detrimental effect on their performance.

    At the request of the Government of Indonesia, an IAEA expert undertook a three-week mission from 18 June 1989 to 7 July 1989 at the Centre for the Application of Isotopes and Radiation (PAIR/BATAN), National Atomic Energy Agency, Jakarta, within the framework of a project entitled: ''Assessment of molasses/multi-nutrient blocks for ruminants in Indonesia (with emphasis on small-farm holders)'' (INS/88/013 - 11.66 - Agricultural Production). The project involves field evaluations of supplementation strategies at a number of provinces and is backed by controlled laboratory studies at PAIR/BATAN. Recent field studies confirm the potential for improved production from goats, sheep, dairy cattle and buffaloes in response to supplementation. The increased production is justified by cost/benefit analysis but further improvements should be possible when least cost supplements are devised for local conditions. The Expert worked closely with the leader of the group in the Animal Nutrition and Production Section, Dr. C. Hendratno, and her staff to interpret, summarize and report on results of recently completed, existing field studies; to initiate new field studies in different provinces of Java; to develop nuclear and other techniques for use in planned intensive laboratory studies aimed at identifying the ingredients in urea-molasses multi-nutrient blocks that are responsible for their success as supplements for goats, dairy cattle and buffaloes in a number of locations in Java.

    Full Text Available Palm kernel cake has a relatively high protein content, however its degradability in the rumen is high resulting in loosing its function as protein source for ruminant. This experiment was aimed toinvestigate the effect of feeding molasses protected palm kernel cake (BIS-M on growth of young male Ettawah Grade (Peranakan Etawah = PE goat. Twenty four (24 PE goats were divided into 4 groups and allocated to respective feeding BIS-M treatments. The treatments were R0 = control (without BIS-M, R1 = 15% BIS-M, R2 = 30% BIS-M and R3 = 45% BIS-M. The concentrate was fed at 400 gh-1d-1 for each individual in all treatment groups, while napier grass (Pennisetum purpureum was offered ad libitum. The live weight of the goats were between 17-18 kg at the beginning of experiment. Feeding trial was carried out for 14 weeks consisting of 2 weeks for preliminary and 12 weeks for growth performance period. The digestibility study of the nutrient was carried out during the last 7 days of the experiment. The experiment was arranged in a completely randomized design with 6 replications. Drinking water was available at any time. Feed intake was recorded daily while the body weight was recorded every 2 weeks. The parameters of observation were feed intake, live weight gain, nutrient digestibility and feed conversion ratio. The results indicated that the dietary treatments affected the intake and digestibility of nutrients, average daily gain and feed conversion ratio (P < 0.05. The total feed dry matter intakes were 599,30; 620,74; 690,19 and 740,04 gh-1d-1 with DM and Protein digestibility of 64.74 and 75.99; 67.47 and 73.05; 70.06 and 73.02; and 72.88 and 72.25% respectively for R0, R1, R2 and R3. The ADG were 42.06; 52.78; 61.90 and 70.24 g; with feed conversion ratio of 14.68; 10.51; 9.08; and 9.85 for R0, R1, R2 and R3. It was concluded that BIS-M can be used as source of protein with optimal utilization level at 30% of the concentrate.

  16. The changing Swiss electricity - Critical views

    International Nuclear Information System (INIS)

    Wilms, E.F.J.

    2001-01-01

    This book takes a critical look at developments in the Swiss electricity market and, in particular, criticises national, regional and local energy policy, which the author considers to be incoherent. The book first describes how the electricity market works, the main players involved and the daily problems that have to be solved. Then, the problems that could be caused by liberalisation, including the question of transit fees, the development of electricity prices for consumers, changes in the structure of the electricity business and third party access are discussed. The second part of the book examines legal aspects of proposed electricity market legislation and then presents 16 propositions covering energy policy, market regulation, unbundling not only of electricity generation, distribution and services but also of politics and business, the revision of proposed liberalisation legislation, taxation aspects as well as the national and international operation of the electricity grid. The book further examines three regional electricity utilities and the attempts to privatise them, which did not meet with the approval of the voting public, and discusses the suspicion cast on certain politicians, that they try to push through the particular interests of groups they are closely associated with. The book is also includes a bibliography and a list of useful addresses

  17. Internet Voting for Expatriates: The Swiss Case

    2014-12-01

    Full Text Available In 2008 the first Swiss canton introduced internet voting for expatriates, thus initiating the second phase in Switzerland’s piecemeal i-voting roll-out. More cantons soon followed, and as of this writing expatriates from 12 out of the 26 cantons can vote online. This paper focuses on the second phase involving expatriates. We address three questions at the core of the internet voting research agenda. First, the popularity question: to what extent do expatriates make use of the new online channel? Second, the ‘who’ question: what is the profile of the typical expatriate i-voter? Finally, the turnout question: did the extension of internet voting to the expatriates have an effect on electoral mobilization? Our findings indicate that the online channel is very popular among expatriates, both if compared to other trials in Switzerland itself and internationally. On the other hand, known patterns regarding the profile of i-voters and the effect on mobilization seem to be also replicated in the expatriate trials. Expatriate i-voters tend to be young, male, and there is some evidence of an upper-class bias. Thus, usage of the online channel seems driven by the digital divide also among expatriates. Moreover, we find some evidence that i-voting did not affect electoral mobilization, similarly to trials involving residents.

    1984-10-01

    Recommended sorption data for use in transport models for a Swiss High-Level Waste repository are presented. The models used in 'Project Gewaehr 1985' assume linear sorption isotherms and require elemental partition coefficient (Kd) data. On the basis of a literature search 'realistic' Kd data for 22 elements have been selected for weathered crystalline rock and sediments in contact with a reducing groundwater and also sediments with a less reducing groundwater. In an appendix sorption data for 28 elements on bentonite backfill are given. These data are supplemented with 'conservative' estimates taken to represent minimum reasonable values. Available data are discussed for each element clearly exhibiting (i) the large gaps in knowledge, (ii) their unbalanced distribution between different elements and, hence, (iii) the need for further experiments in the laboratory, the field and analogue studies. An overview of the theoretical concepts of sorption, experimental methodology and data interpretation is given in order to put the values into context. General problem areas are identified. (Auth.)

    The production of poly(γ-glutamic acid) by Bacillus subtilis NX-2 from cane molasses and monosodium glutamate waste liquor (MGWL) was studied for the first time in this work. When batch fermentation was carried out with untreated molasses, 33.6±0.37 g L(-1) PGA was obtained with a productivity of 0.46±0.006 g L(-1) h(-1). In order to minimize the substrate inhibition, fed-batch fermentation was performed with untreated or hydrolyzed molasses in 7.5 L bioreactor, giving 50.2±0.53 and 51.1±0.51 g L(-1) of PGA at 96 h, respectively. Further studies were carried out by using MGWL as another carbon source, resulting in a PGA concentration of 52.1±0.52 g L(-1) with a productivity of 0.54±0.003 g L(-1) h(-1). These results suggest that the low-cost cane molasses and MGWL can be used for the environmental-friendly and economical production of PGA by B. subtilis NX-2. Copyright © 2012 Elsevier Ltd.

    2004-02-01

    To explore whether self-reported happiness is associated with mental and physical health status among young adults. Cross-sectional survey of 1257 randomly selected university students in Geneva, Switzerland. The questionnaire included an item that probed the feeling of happiness in the past month, the Short Form-12 health survey (from which mental and physical health scores were computed), scales to measure self-esteem, stress, and social support, reports of various life problems, and sociodemographic information. Most participants felt happy all of the time or most of the time (63%). In multivariate analysis, feeling happy all or most of the time was strongly associated with better mental health (odds ratios for consecutive quartiles of mental health scores: 1.0 (reference), 6.8 (95% confidence interval (CI): 4.5-10.1), 19.2 (95% CI: 12.2-30.2), 39.9 (95% CI: 22.4-71.0)), but also with the feeling of getting enough love and affection (item from the social support scale, odds ratio: 1.9; 95% CI: 1.4-2.7), female sex (odds ratio: 1.5; 95% CI: 1.1-2.1), being Swiss (odds ratio: 1.8; 95% CI: 1.3-2.5), and higher self-esteem (odds ratios for consecutive quartiles ranged from 1.0 to 3.5, 95% CI: 2.1-5.8). The association between happiness and physical health was weak and statistically non-significant. The strong association between happiness and mental health suggests that asking people if they are happy may help identify mental health care needs. Self-reported happiness may also be a useful outcome measure for evaluation of health interventions.

    1999-01-01

    Full Text Available Infection of Swiss/NIH mice with Leishmania major was compared with infection in isogenic resistant C57BL/6 and susceptible BALB/c mice. Swiss/NIH mice showed self-controlled lesions in the injected foot pad. The production of high levels of interferon-g (IFN-g and low levels of interleukin-4 (IL-4 by cells from these animals suggests that they mount a Th1-type immune response. The importance of the indigenous microbiota on the development of murine leishmaniasis was investigated by infecting germfree Swiss/NIH in the hind footpad with L. major and conventionalizing after 3 weeks of infection. Lesions from conventionalized Swiss/NIH mice were significantly larger than conventional mice. Histopathological analysis of lesions from conventionalized animals showed abscesses of variable shapes and sizes and high numbers of parasitized macrophages. In the lesions from conventional mice, besides the absence of abscess formation, parasites were rarely observed. On the other hand, cells from conventional and conventionalized mice produced similar Th1-type response characterized by high levels of IFN-g and low levels of IL-4. In this study, we demonstrated that Swiss/NIH mice are resistant to L. major infection and that the absence of the normal microbiota at the beginning of infection significantly influenced the lesion size and the inflammatory response at the site of infection.

  4. Swiss electricity production into the future

    Steinmann, Walter

    2008-01-01

    In January 2007 the Swiss Federal Office of Energy's work on energy perspectives up until 2035 were concluded and presented. The results form the basis for political debate on the future direction of Switzerland's energy and climate policies. The energy perspectives point to an increase in demand for electricity in Switzerland by 2035 of around 20% and a deficit of roughly 17 billion kWh if no extra measures are taken. This corresponds to twice the annual production of a Swiss nuclear power station. This development and the unharnessed potential in the areas of efficiency and renewable energies prompted Switzerland's Federal Council to decide on a reorientation of its energy policy in 2007. This is based on four pillars: 1. Improved energy efficiency; 2. Promotion of renewable energy; 3. Targeted extension and construction of large-scale power stations; 4. Intensification of foreign energy policy, particularly in terms of cooperation with the EU. 2008 has got off to a strong start in terms of energy policy - the CO 2 tax on fuels has been introduced and the first package of the new Energy Supply Act (StromVG) has entered into force. The new Electricity Supply Act creates the necessary conditions for a progressive opening of Switzerland's electricity market. From 2009 some 50,000 large customers with an annual electricity consumption of over 100 megawatt hours will be able to benefit from this partial opening and be free to choose their power suppliers. But all other power consumers will benefit right from the start too because their electricity suppliers will also be able to buy in their electricity from the free market and pass on any price savings to their customers. Furthermore, the Electricity Supply Act delivers a clear legal framework for cross-border trade in electricity. In actual fact the opening of the electricity market is already well advanced around Switzerland. Liberalisation also results in cost transparency: As the opening of the electricity market

    The 'nuclea' meeting of the Swiss Nuclear Forum with the focus on 'The Future of Nuclear Power in the Energy Mix' was held on the premises of the Swiss Leibstadt nuclear power station in late October. The electricity gap is a reality; the underlying facts are known by now, but this does not make them any less threatening and worrying. This is one of the key findings of the meeting. Experience over the past 3 decades has confirmed the close link between the gross domestic product and electricity consumption. Separating economic growth from the electricity requirement had remained wishful thinking. Consequently, the replacement and expansion of existing generating capacities had to take into account that nuclear power, among other things, met the stringent requirements with respect to climate protection and continuity of supply. There was agreement at 'nuclea' about nuclear power remaining an indispensable component in the energy mix for Swiss electricity supply. (orig.)

    We study a vehicular traffic scenario on Swiss roads in an emergency situation, calculating how sequentially roads block due to excessive traffic load until global collapse (gridlock) occurs and in this way displays the fragilities of the system. We used a database from Bundesamt für Raumentwicklung which contains length and maximum allowed speed of all roads in Switzerland. The present work could be interesting for government agencies in planning and managing for emergency logistics for a country or a big city. The model used to generate the flux on the Swiss road network was proposed by Mendes et al. [Physica A 391, 362 (2012)]. It is based on the conservation of the number of vehicles and allows for an easy and fast way to follow the formation of traffic jams in large systems. We also analyze the difference between a nonlinear and a linear model and the distribution of fluxes on the Swiss road.

    PHASE is a software tool for physical optics simulation based on the stationary phase approximation method. The code is under continuous development since about 20 years and has been used for instance for fundamental studies and ray tracing of various beamlines at the Swiss Light Source. Along with the planning for SwissFEL a new hard X-ray free electron laser under construction, new features have been added to permit practical performance predictions including diffraction effects which emerge with the fully coherent source. We present the application of the package on the example of the ARAMIS 1 beamline at SwissFEL. The X-ray pulse calculated with GENESIS and given as an electrical field distribution has been propagated through the beamline to the sample position. We demonstrate the new features of PHASE like the treatment of measured figure errors, apertures and coatings of the mirrors and the application of Fourier optics propagators for free space propagation.

    This article presents a method for the estimation of the methane emissions caused by the Swiss gas industry. Based on new data on the Swiss gas infrastructure, current emission levels are estimated for methane - one of the major greenhouse gases. The methodology and modelling used, which is based on previous studies on this topic, are discussed. Results are presented that show that the estimates provided by the current study are consistent with earlier data. Scenarios are presented that show that a steady decrease in methane emissions emanating from the Swiss gas industry's installations can be expected by the year 2012. The data used in the study and its results are presented in tabular and graphical form and commented on

    SWISS-PROT is a protein sequence database, which aims to be nonredundant, fully annotated and highly cross-referenced. Most eukaryotic gene products undergo co- and/or post-translational modifications, and these need to be included in the database in order to describe the mature protein. SWISS-PROT includes information on many types of different protein modifications. As glycosylation is the most common type of post-translational protein modification, we are currently placing an emphasis on annotation of protein glycosylation in SWISS-PROT. Information on the position of the sugar within the polypeptide chain, the reducing terminal linkage as well as additional information on biological function of the sugar is included in the database. In this paper we describe how we account for the different types of protein glycosylation, namely N-linked glycosylation, O-linked glycosylation, proteoglycans, C-linked glycosylation and the attachment of glycosyl-phosphatidylinosital anchors to proteins.

    There is increasing evidence that genetic factors are associated with ischemic stroke, including multiple recent reports of association with the gene PDE4D, encoding phosphodiesterase 4D, on chromosome 5q12. Genetic studies of stroke are important but can be logistically difficult to perform. This article reviews the design of the Siblings With Ischemic Stroke Study (SWISS) and discusses problems in performing a sibling-based pedigree study where proband-initiated consent is used to enroll pedigree members. Proband-initiated enrollment optimizes privacy protections for family members, but it is associated with a substantial pedigree non-completion rate such that 3 to 4 probands must be identified to obtain one completed sibling pedigree. This report updates the progress of enrollment in the SWISS protocol, discusses barriers to pedigree completion and describes innovative approaches used by the SWISS investigators to enhance enrollment.

    Full Text Available Grifola frondosa is an edible Basidiomycete and produces exopolysaccharides (EPS known for their antitumour activity. The objectives of this study are to produce exopolysaccharides in submerged fermentation using alternative carbon sources (sugar cane and soy molasses, and to evaluate their anti-proliferative activity against tumour cells. Exopolysaccharides were extracted by ethanol and tested against mice tumour cells, then characterized by gas chromatography. Carbon sources represent the major cost of the bioprocess, so a search for new alternatives such as agro-industrial residues is important to establish the viability on an industrial scale. Moreover, the data about the kinetics of the EPS production allow studying the optimization of the process.

    To compare the efficiency of various whole cell immobilization techniques for the production of gluconic acid by Aspergillus niger were investigated using potassium ferrocyanide-treated cane molasses as the substrate. The techniques followed were: (1) Calcium alginate entrapment, (2) cross-linking with glutaraldehyde after cell permeabilization with (a) acetone, (b) toluene and (c) isopropanol and (3) development of granular catalyst. A comparative analysis of yield has revealed that calcium alginate entrapment was the most suitable technique as it had given the maximum product yield (0.40 g gluconic acid/g total reducing sugar supplied). The properties of immobilized A. niger in sodium alginate gel have been thoroughly investigated and compared with those of free cells under most suitable conditions of fermentation. (orig.)

    This study aimed to investigate the interaction between methane production performance and active microbial community dynamics at different loading rates by increasing influent substrate concentration. The model system was an upflow anaerobic sludge blanket (UASB) reactor using molasses wastewater. The active microbial community was analyzed using a ribosomal RNA-based approach in order to reflect active members in the UASB system. The methane production rate (MPR) increased with an increase in organic loading rate (OLR) from 3.6 to 5.5 g COD·L(-1)·day(-1) and then it decreased with further OLR addition until 9.7 g COD·L(-1)·day(-1). The UASB reactor achieved a maximum methane production rate of 0.48 L·L(-1)·day(-1) with a chemical oxygen demand (COD) removal efficiency of 91.2 % at an influent molasses concentration of 16 g COD·L(-1) (OLR of 5.5 g COD·L(-1)·day(-1)). In the archaeal community, Methanosarcina was predominant irrespective of loading rate, and the relative abundance of Methanosaeta increased with loading rate. In the bacterial community, Firmicutes and Eubacteriaceae were relatively abundant in the loading conditions tested. The network analysis between operation parameters and microbial community indicated that MPR was positively associated with most methanogenic archaea, including the relatively abundant Methanosarcina and Methanosaeta, except Methanofollis. The most abundant Methanosarcina was negatively associated with Bifidobacterium and Methanosaeta, whereas Methanosaeta was positively associated with Bifidobacterium.

    Molasses fermentation performance by both a cryotolerant and a thermophilic yeast (strain AXAZ-1) isolated from grapes in Greece was evaluated in an extremely wide temperature range (3-40 degrees C). Sequence analysis of the 5.8S internal transcribed spacer and the D1/D2 ribosomal DNA (rDNA) regions assigned isolate to Saccharomyces cerevisiae. Restriction fragment length polymorphism of the mitochondrial DNA showed that strain AXAZ-1 is genetically divergent compared to other wild strains of Greek origin or commercial yeast starters. Yeast cells growing planktonically were capable of fermentation in a wide temperature spectrum, ranging from 3 degrees C to 38 degrees C. Immobilization of yeast on brewer's spent grains (BSG) improved the thermo-tolerance of the strain and enabled fermentation at 40 degrees C. Time to complete fermentation with the immobilized yeast ranged from 20 days at 3 to 38 h at 40 degrees C. The daily ethanol productivity reached maximum (58.1 g/L) and minimum (2.5 g/L) levels at 30 and 3 degrees C, respectively. The aroma-related compounds' profiles of immobilized cells at different fermentation temperatures were evaluated by using solid phase microextraction (SPME) gas chromatography-mass spectrometry (GC-MS). Molasses fermentation resulted in a high quality fermentation product due to the low concentrations of higher and amyl alcohols at all temperatures tested. Strain AXAZ-1 is very promising for the production of ethanol from low cost raw materials, as it was capable to perform fermentations of high ethanol concentration and productivities in both low and high temperatures.

    The aim of this study was to evaluate the effect of replacing corn grain for sugar cane molasses (MO) or glucose syrup (GS) in the starter concentrate on performance and metabolism of dairy calves. Thirty-six individually housed Holstein male calves were blocked according to weight and date of birth and assigned to one of the starter feed treatments, during an 8 week study: i) starter containing 65% corn with no MO or GS (0MO); ii) starter containing 60% corn and 5% MO (5MO); iii) starter containing 55% corn and 10% MO (10MO); and iv) starter containing 60% corn and 5% GS (5GS). Animals received 4 L of milk replacer daily (20 crude protein, 16 ether extract, 12.5% solids), divided in two meals (0700 and 1700 h). Starter and water were provided ad libitum. Starter intake and fecal score were monitored daily until animals were eight weeks old. Body weight and measurements (withers height, hip width and heart girth) were measured weekly before the morning feeding. From the second week of age, blood samples were collected weekly, 2 h after the morning feeding, for glucose, β-hydroxybutyrate and lactate determination. Ruminal fluid was collected at 4, 6, and 8 weeks of age using an oro-ruminal probe and a suction pump for determination of pH and short-chain fatty acids (SCFA). At the end of the eighth week, animals were harvested to evaluate development of the proximal digestive tract. The composition of the starter did not affect (p>0.05) concentrate intake, weight gain, fecal score, blood parameters, and rumen development. However, treatment 5MO showed higher (p0.05). Thus, it can be concluded that the replacement of corn by 5% or 10% sugar cane molasses or 5% GS on starter concentrate did not impact performance, however it has some positive effects on rumen fermentation which may be beneficial for calves with a developing rumen.

    The aim of this work was to develop an effective fed-batch feeding strategy to enhance recombinant glucose isomerase (r-GI) production by recombinant Escherichia coli BL21 (DE3) pLysS on an industrially relevant feedstock without the application of an exogenous inducer. Following the batch operation (0 < t < 7 H), the effects of pulse and/or continuous feeding of hydrolyzed beet molasses were investigated under five different feeding strategies. The two most promising strategies with respect to r-GI activity were (i) PM-0.05, designed with one pulse feed (t = 7 H) followed by a continuous feed and (ii) 2PM F -0.05, designed with two consecutive pulse feeds (t = 7 and 10 H) followed by a continuous feed. The continuous feeding of molasses for both fermentation strategies employed the same precalculated feeding rate, μ o = 0.05 H -1 . The maximum r-GI activities exhibited by PM-0.05 and 2PM F -0.05 were 29,050 and 30,642 U dm -3 , respectively. On the one hand, compared to PM-0.05 r-GI activity reached its maximum within a shorter cultivation time (∆t max = 2 H) at 2PM F -0.05, which could be preferable in terms of manufacturing costs and possible risks; on the other hand, PM-0.05 is a simpler fermentation regime compared to 2PM F -0.05 with respect to manipulations that should be considered in large-scale production. © 2017 International Union of Biochemistry and Molecular Biology, Inc.

    Enhanced bioremediation, which involves introduction of amendments to promote biodegradation, increasingly is used to accelerate cleanup of recalcitrant compounds and has been identified as the preferred remedial treatment at many contaminated sites. Although blind introduction of amendments can lead to sub-optimal or ineffective remediation, the distribution of amendment throughout the treatment zone is difficult to measure using conventional sampling. Because amendments and their degradation products commonly have electrical properties that differ from those of ambient soil, time-lapse electrical geophysical monitoring has the potential to verify amendment emplacement and distribution. In order for geophysical monitoring to be useful, however, results of the injection ideally should be accessible in near real time. In August 2010, we demonstrated the feasibility of near real-time, autonomous electrical geophysical monitoring of amendment injections at the former Defense Reutilization and Marketing Office (DRMO) in Brandywine, Maryland. Two injections of about 1000 gallons each of molasses, a widely used amendment for enhanced bioremediation, were monitored using measurements taken with borehole and surface electrodes. During the injections, multi-channel resistance data were recorded; data were transmitted to a server and processed using a parallel resistivity inversion code; and results in the form of time-lapse imagery subsequently were posted to a website. This process occurred automatically without human intervention. The resulting time-lapse imagery clearly showed the evolution of the molasses plume. The delay between measurements and online delivery of images was between 45 and 60 minutes, thus providing actionable information that could support decisions about field procedures and a check on whether amendment reached target zones. This experiment demonstrates the feasibility of using electrical imaging as a monitoring tool both during amendment emplacement

    On June 7 , 1998, the Swiss citizens voted on a constitutional amendment, which could have jeopardised the future of biotechnological research in Switzerland. Scientists and opinion leaders around the world expected the referendum with great anxiety. 'Nature', in an editorial, had firmly stated that the Swiss way showed 'how not to run a country', the 'Economist', a week prior to the referendum, had written that the Swiss might be the only people in the world who decided on their own to forego a world class position in scientific research. In fact, the Swiss did none of that. They rejected the constitutional amendment with an overwhelming majority of 67 per cent of the votes, and what started out as a dramatic threat to scientific research in Switzerland became a platform in favour of modern biotechnology. The presentation addresses some of the key features of the Swiss biotech campaign, analyses the success factors of the campaign, provides an insight in the most in-depth collection of data on public perception of biotechnology in the world, and draws conclusions as to what extent the Swiss experience can be of use in the way to communicate on modem science. The result of the Swiss referendum has convincingly shown that successful communication of modem science is possible if - scientists, authorities, and the industry accept the challenge to cope with the demands of communicating with the public at large, - there is a clear understanding that the public's needs may often be based on psychological rather than on logic scientific reasons, - all participants in the dialogue are willing to forego scientific jargon for clear understandable language, i.e. understand that it is hardly the public's fault if messages do not get across, - everybody accepts that dialogue, information, and education on modem science is a long-haul task. The Swiss biotech referendum was seen as a major threat to Switzerland as a leading country of scientific research. However, something which

    A detailed Late-Glacial radiocarbon stratigraphy for the Swiss Plateau has been established on the basis of over 90 accelerator 14 C dates on terrestrial plant macrofossils. A comparison of the radiocarbon ages derived from terrestrial, telmatic and limnic material at different sites on the Swiss Plateau yields a proposal for modifying the zonation system of Welten for the Late-Glacial. By retaining the limits of chronozones and by refining the palynostratigraphic criteria for the limits of biozones, a separation between chrono- and biozonation at the beginning of the Boelling and the Younger Dryas becomes obvious. 54 refs

    A world without Weapons of Mass Destruction - this is the vision of SPIEZ LABORATORY, Switzerland. As the federal establishment for NBC defense, it deals with the protection from nuclear, biological, and chemical threats and risks, as well as with the technical aspects of arms control and disarmament of nuclear, biological, and chemical weapons (NBC weapons). Now on the occasion of the 10th anniversary of the Chemical Weapons Convention (CWC), it is the right time to look back on the achievements of the OPCW and on how a small country like Switzerland can support an international organization such as the OPCW on its way to a world free of chemical weapons. SPIEZ LABORATORY was involved in the negotiations during the Conference on Disarmament in Geneva which in turn led to the CWC. Switzerland in general and SPIEZ LABORATORY in particular, have played an active role in different areas relevant to the CWC, all in order to get closer to a w orld without Weapons of Mass Destruction . The support of the OPCW and different Member States covered fundamental parts of the Convention such as, chemical weapon destruction (financial contribution and analytical work) and the implementation of Article VII obligations (declaration support, information and experience exchange). In addition, Switzerland and SPIEZ LABORATORY still have an important role in assistance and protection. Switzerland submitted a proposal for the delivery of protective equipment to the OPCW and is also active in capacity building courses like CITPRO or SEFLAB. The support in the field of international cooperation and assistance is expressed by numerous internships in SPIEZ LABORATORY and in the Swiss industry. In order to support the operability of the OPCW, SPIEZ LABORATORY participates in inspector training modules (basic modules, mock inspections) and delivers on a regular basis reference chemicals and analytical data (by now 2/3 of all the data has been inputted into the OPCW Central Analytical

    The Miocene Sivas Basin is located within a collision zone, forming one of the largest basins in Central Turkey that developed unconformably on a foundered Paleozoic-Mesozoic basement and Eocene-Oligocene deposits. The time and space relationships of sedimentary environments and depositional evolution of Lower to Middle Miocene rocks exposed between Zara and Hafik towns is studied. A 4 km thick continuous section is subdivided into the Agilkaya and Egribucak Formations. Each formation shows an overall fining upward trend and contains three members. Although a complete section is present at the western part (near Hafik) of the basin, to the east the uppermost two members (near Zara) are absent. The lower members of both formations are composed of fluvial sheet-sandstone and red mudstone that migrate laterally on a flood basin within a semi-arid fan system. In the Agilkaya Formation that crops out near Zara, alluvial fans composed of red-pink volcanic pebbles are also present. The middle members are composed of bedded to massive gypsum and red-green mudstone of a coastal and/or continental sabkha environment. While the massive gypsum beds reach several 10’s of m in Hafik area, near Zara, they are only few m thick and alternate with green mudstones. In Hafik, bedded gypsums are intercalated with lagoonal dolomitic limestone and bituminous shale in the Agilkaya Formation and with fluvial red-pink sandstone-red mudstone in the Egribucak Formation. The upper members are made up of fossiliferous mudstone and discontinuous sandy limestone beds with gutter casts, HCS, and 3-D ripples. They indicate storm-induced sedimentation in a shallow marine setting. The disorganized accumulations of ostreid and cerithiid shells, interpreted as coquina bars, are the products of storm generated reworking processes in brackish environments. Rapid vertical and horizontal facies changes and the facies associations in both formations reflect the locally subsiding nature of this molassic

    Compared to conventional boilers, heating by heat pumps cuts down fuel consumption and CO{sub 2} emissions to about 50%. Compared to electric resistance heating, the energy consumption is even reduced up to 80%. Therefore, the impressive market penetration growth of heat pumps will continue. Swiss pioneers were the first to realize functioning vapour recompression plants. The first European heat pumps were realized in Switzerland. To date it remains one of the heat pump champions. Swiss pioneering work in the development of borehole heat exchangers, sewage heat recovery, oil free piston compressors and turbo compressors is well known. The biggest heat pump ever built comes from Switzerland. Although there is a fairly comprehensive natural gas distribution grid, 75% of the new single-family homes built in Switzerland are currently heated by heat pumps. This paper presents some of the highlights of this success story focusing on Swiss developments and relating them to the international milestones. In order to indicate the direction in which the future development might go to, some recent Swiss research projects are presented as well. (author)

    15 November 2002 Reimbursement of Swiss income tax The Swiss authorities have introduced a new system of taxation with effect from this year onwards. The main feature of this new system is that the tax year henceforth coincides with the year in which income is earned. One major practical consequence is that Swiss members of the personnel will receive a provisional income tax demand that must be settled by the date shown; however, the final income tax demand will not be sent until up to several months later. Hitherto, the CERN Administration only recognised this final demand as proof of payment for the reimbursement of Swiss income tax. In view of the delay the new procedure will generate between the settlement of the provisional demand and receipt of the final demand, and to avoid members of the personnel having to bear the cost of an advance payment, the CERN Administration has decided to align its reimbursement procedure with the new system of taxation. In future, the provisional income tax demand will also...

    This report for the Swiss Federal Office of Energy (SFOE) examines the possibilities of using Switzerland's hydropower generation facilities as a means of control and as a capacity-reserve for a European power system that includes a considerable amount of wind-generated electricity. The aims of the study - the analysis of possible changes in power availability and of the relative importance of peak load compensation, economic optimisation potential for the use of Swiss hydropower and organisational aspects - are presented. Various methods for organising production timetables and trading are looked at, as are future developments in the European power market. Methods of assessment of the value of Swiss hydropower installations are discussed in detail and possibilities of increasing capacity are discussed. The report is concluded with recommendations on the participation of Swiss hydropower in the market for regulation energy and the development of associated strategies. Also, environmental aspects are examined and the influence of national wind-energy concepts are discussed.

    Full text: The Swiss Utility Working group for ageing Management (AM) presented their programme for the first time at the PLIM/PLEX 93. In the meantime the key guideline documents have been prepared and the most so called S teckbrief - files for Safety Class 1 (SC1) are issued. The 'Steckbrief' file is a summary of the component history and includes the results of the Reviews performed and measures taken or planned to counteract ageing mechanisms. The scope of these activities does not only serve the important aspect of reliable plant service but also facilitates component and plant life extension feasibility. The older plants have been operated now for up to 30 years, so PLEX will become a more important topic for Swiss NPP. It is very encouraging, that there is an official memorandum of the Swiss authority with the clear statement, that they could not identify any technical reason, why the older plants should not extend their design life of 40 years for at least 10 and the younger for 20 years. The result of this is that a well established Ageing Management Programme (AMP) provide a good basis for Plant Life Extension (PLEX), e.g. the Swiss AMP has to be seen as a PLIM. (author)

  1. Automatically extracting functionally equivalent proteins from SwissProt

    Full Text Available Abstract Background There is a frequent need to obtain sets of functionally equivalent homologous proteins (FEPs from different species. While it is usually the case that orthology implies functional equivalence, this is not always true; therefore datasets of orthologous proteins are not appropriate. The information relevant to extracting FEPs is contained in databanks such as UniProtKB/Swiss-Prot and a manual analysis of these data allow FEPs to be extracted on a one-off basis. However there has been no resource allowing the easy, automatic extraction of groups of FEPs – for example, all instances of protein C. We have developed FOSTA, an automatically generated database of FEPs annotated as having the same function in UniProtKB/Swiss-Prot which can be used for large-scale analysis. The method builds a candidate list of homologues and filters out functionally diverged proteins on the basis of functional annotations using a simple text mining approach. Results Large scale evaluation of our FEP extraction method is difficult as there is no gold-standard dataset against which the method can be benchmarked. However, a manual analysis of five protein families confirmed a high level of performance. A more extensive comparison with two manually verified functional equivalence datasets also demonstrated very good performance. Conclusion In summary, FOSTA provides an automated analysis of annotations in UniProtKB/Swiss-Prot to enable groups of proteins already annotated as functionally equivalent, to be extracted. Our results demonstrate that the vast majority of UniProtKB/Swiss-Prot functional annotations are of high quality, and that FOSTA can interpret annotations successfully. Where FOSTA is not successful, we are able to highlight inconsistencies in UniProtKB/Swiss-Prot annotation. Most of these would have presented equal difficulties for manual interpretation of annotations. We discuss limitations and possible future extensions to FOSTA, and

    In 1994 the Swiss nuclear power plants produced their highest-ever combined annual output. Their contribution to total electricity generation in the country was 36%. At Muehleberg the power uprate, undertaken in 1993, was effective for the first time for an entire year. The larger capacity of the new steam generators installed in 1993 in unit 1 of the Beznau NPP allows for an electric output of 103% of nominal power. The plant efficiency of the Goesgen and Leibstadt units was increased by replacing the low pressure turbines by the new ones with a modern design. The application for a power uprate of the Leibstadt reactor is still pending. For the first time in Switzerland, one of the reactor units, Beznau 2, operated on an extended cycle of one and a half years, with no refuelling outage in 1994. In spite of the replacements of two of its three low pressure turbines, Goesgen had the shortest refuelling shutdown since the start of commercial operation. The average number of reactor scrams at the Swiss plants remained stable, at less than one scram per reactor year. Re-inspection of crack indications detected in 1990 in the core shroud of the Muehleberg reactor revealed no significant changes. A crack indication was found in one of the other welds inspected. The Swiss government issued a limited operating licence for Beznau 2 for the next ten years, i.e. until the end of 2004. The only other unit with a limited operating licence (until 2003) is Muehleberg. The remaining three reactor units, have no time limits on their operating licences, in accordance with the Atomic Law. Goesgen is the first Swiss nuclear power plant having now produced more than 100 billion kWh. As from January 1, 1995, the nominal net power of the largest Swiss reactor unit, Leibstadt, has been fixed at 1030 MW; that of the Goesgen NPP has been increased by 25 MW to 965 MW.

    Full Text Available Saccharomyces cerevisiae (PTCC 24860 growth on pretreated sugar beet molasses was an optimized via statistical approach. In order to liberate all monomeric sugars, pretreated sugar beet molasses with dilute acid was obtained. The influence of process parameters such as sugar concentration, nitrogen source, pH and incubation time on the cell growth were investigated by a design expert software with the application of a central composite design (CCD under response surface methodology (RSM. The optimal culture conditions were pH of 5.3, incubation time of 24 h and medium composition of 35 g reduced sugars, 1.5 g NH4Cl and 1 g yeast extract per liter of the media. At optimal cell growth conditions and incubation time of 12 h, the maximum ethanol production of 14.87 g/L was obtained.

    Highly fermentable fibre sources like sugar beet pulp (SBP) might be fed as an alternative to starch rich concentrate to horses. However, including soluble fibre from SBP in a meal of con-centrate might delay gastric emptying and increase viscosity in the small intestine, altering or impairing...... glucose absorption, hence affect the metabolic responses measured in plasma and the hindgut. Four diets with different carbohydrate composition were investigated in a 4 × 4 Latin square design experiment in four periods using four caecum cannulated Norwegian coldblooded trotter horses. The diets were hay...... intestine in response to the dietary carbohydrate composition. In conclusion, there was no effect of adding molassed SBP to a meal of barley compared to feeding barley alone, and fluctuations in plasma and caecal variables were more stable when feeding hay and molassed SBP than feeding barley....

    Full Text Available The rate of decomposition of sugar cane leaves mixed with an organic fertilizer compost type was evaluated, using a finite accelerator (molasses and an infinity accelerator (effective microorganisms. The trial was conducted in the greenhouse facilities of the National University of Colombia in Palmira. The results showed that molasses is a decomposition accelerator of the wastes of sugar cane leaf, since it shows a marked influence on the initial decomposition rate of the waste, but once the carbohydrates that constitute it are consumed, the rate of decomposition decreases significantly. Then the potential is evident on the waste of sugar cane leaf elements for the maintenance and/or biophysical capital improvement in the productive system of the sugar cane, as the result of their high photosynthetic efficiency.

    Beet molasses, the principal raw material of molasses distilleries and yeast factories, have in recent times with increasing frequency shown negative effects on the fermentation and quality of baking yeast. Based on the fact that with many ``problem molasses`` the inhibitory effect on fermentation can be substantially reduced and often even totally eliminated by prior aeration of the hot acidic molasses solution, the chemical-analytical and biological investigations presented here focused on the components of such problem molasses volatilizable in water vapour. The water vapour distillates contain, in particular, low carbon acids (C1-C10), and alkanols (C6-C7), the minimum inhibitory concentrations (m.i.c.) of which for yeast fermentation were established. This showed very high m.i.c. levels for an inhibitory effect on fermentation, which in practice are not reached by the individual carbon acid and alkanol constituents of the problem molasses. However, these acids and alcohols exhibit marked synergic effects which were confirmed by determining the m.i.c. values of mixtures. The inhibitory effect on yeast fermentation is due above all to the presence in problem molasses of butyric acid + caprilic acid + hexanol and heptanol. (orig.)

    Many biofuel standards, including California's recently adopted low carbon fuel standard, consider just one feedstock from one supplying country for the production of sugarcane ethanol: fresh mill-pressed cane juice from a Brazilian factory. While cane juice is the dominant feedstock for ethanol in most Brazilian factories, a large number of producers in Indonesia, India, and the Caribbean, and a significant number in Brazil, manufacture most of their ethanol from molasses, a low value co-product of raw sugar. Several producers in these countries have the capacity to export ethanol to California, but the GREET (from: greenhouse gas, regulated emissions and energy use in transportation) model, which is the LCA (lifecycle assessment) model of choice for most biofuel regulators including California, does not currently include this production pathway. We develop a modification to GREET to account for this pathway. We use the upstream and process lifecycle results from the existing GREET model for Brazilian ethanol to derive lifecycle greenhouse gas emissions for ethanol manufactured from any combination of molasses and fresh cane juice. We find that ethanol manufactured with only molasses as a feedstock with all other processes and inputs identical to those of the average Brazilian mill has a lifecycle GHG (greenhouse gas) rating of 15.1 gCO 2 - eq MJ -1 , which is significantly lower than the current California-GREET assigned rating of 26.6 gCO 2 - eq MJ -1 . Our model can be applied at any level of granulation from the individual factory to an industry-wide average. We examine some ways in which current sugarcane producers could inaccurately claim this molasses credit. We discuss methods for addressing this in regulation.

    Laccases are used in numerous applications, from green degradation of various xenobiotic compounds, waste detoxification, textile dye bleaching, and delignification of lignocellulose materials to biofuel production. In this study, the recombinant Yarrowia lipolytica YL4 strain carrying the white-rot fungus Trametes versicolor laccase IIIb gene was used for laccase production from beet molasses as an agro-industrial residue. Response surface methodology was used to statistical optimization of the production of laccase by Y. lipolytica using an industrial medium containing molasses which allows a six times increase in laccase activity compared to primary medium contains glucose after 144 h. In bioreactor cultivation after 48 h, laccase production reached to 3.7- and 22.5-fold more than optimized and primary media in shake-flask cultures, respectively. Laccase productivity in bioreactor (0.0937 U/h) was higher than shake-flask culture (0.0084 U/h). The present study provides valuable information about statistical optimization of bioprocess development for cost-effective production of laccase and other heterologous proteins in Y. lipolytica from beet molasses as sole carbon source, thus allowing the valorization and decreasing environmental pollution of this agro-industrial waste.

    Agro-industrial wastes have been used as substrate-support in solid state fermentation for enzyme production. Molasses and sugarcane bagasse are by-products of sugar industry and can be employed as substrates for invertase production. Invertase is an important enzyme for sweeteners development. In this study, a xerophilic fungus Aspergillus niger GH1 isolated of the Mexican semi-desert, previously reported as an invertase over-producer strain was used. Molasses from Mexico and Cuba were chemically analyzed (total and reducer sugars, nitrogen and phosphorous contents); the last one was selected based on chemical composition. Fermentations were performed using virgin and hydrolyzate bagasse (treatment with concentrated sulfuric acid). Results indicated that, the enzymatic yield (5231 U/L) is higher than those reported by other A. niger strains under solid state fermentation, using hydrolyzate bagasse. The acid hydrolysis promotes availability of fermentable sugars. In addition, maximum invertase activity was detected at 24 h using low substrate concentration, which may reduce production costs. This study presents an alternative method for invertase production using a xerophilic fungus isolated from Mexican semi-desert and inexpensive substrates (molasses and sugarcane bagasse).

    Waste molasses is one of the most important feedstock for ethanol production in Brazil as well as in many Southeast Asian countries, including China. Sulfuric acid pretreatment is employed in most ethanol distilleries in China to control bacterial contamination, which results in difficulties in the treatment of wastewater containing high levels of sulfate ions. In this study, a high efficiency, non-sterilized, continuous ethanol fermentation process without sulfuric acid pretreatment was developed using the flocculating yeast strain KF-7 and the widely utilized, traditional, stirred tank reactors. An alternative molasses medium feeding method, which differs from traditional methods, is proposed that effectively controls bacterial contamination. Separate feeding of 1.2-fold diluted molasses and tap water into the reactor proved to be effective against bacterial contamination during long-term continuous fermentation. By feeding yeast cells with high metabolic activity to the second reactor, a two-stage continuous fermentation process that yielded a high ethanol concentration of 80 g/l as well as high ethanol productivity of 6.6 g/l/h was successfully operated for more than one month. This fermentation process can be applied to ethanol distilleries in which traditional tank reactors are used. 2009 The Society for Biotechnology, Japan. Published by Elsevier B.V.

    The objective of this study was to evaluate the effects of molasses and propionic acid on the fermentation quality and aerobic stability of total mixed ration (TMR) silages prepared with whole-plant corn in Tibet. TMR (354 g/kg DM) was ensiled with four different treatments: no additive (control), molasses (M), propionic acid (P), and molasses+propionic acid (PM), in laboratory silos (250 mL) and fermented for 45 d. Silos were opened and silages were subjected to an aerobic stability test for 12 days, in which chemical and microbiological parameters of TMR silages were measured to determined the aerobic deterioration. After 45 d of ensiling, the four TMR silages were of good quality with low pH value and ammonia/total N (AN), and high lactic acid (LA) content and V-scores. M silage showed the highest (p105 cfu/g FM), however, it appeared to be more stable as indicated by a delayed pH value increase. P and PM silages showed fewer yeasts (ensiling, and apparently preserved available sugars which stimulated large increases in lactic acid during aerobic exposure stage, which resulted in greater aerobic stability of TMR silage.

    The Mesozoic northern Yangtze foreland basin system was formed by continental collision between the North China and South China plates along the Mianlue suture. Synorogenic stratigraphic sequences of Late Triassic to Early-Middle Jurassic age were developed in the northern Yangtze foreland basin. The upper Middle Jurassic Shaximiao Formation consists mainly of thick-bedded terrestrial successions that serve as the main body of the basin-filling sequences, suggesting intense tectonism in the peripheral orogeny of the foreland basin. Laser-ICP-MS U-Pb analysis of 254 detrital zircon grains from sandstone samples and several published Lower-Middle Jurassic samples, detrital compositions, petrofacies, and paleocurrent reconstructions in the northern Yangtze foreland basin indicate that discrete source areas included the Qinling-Dabieshan ranges and the Mianlue suture zone to the north, and the South China plate to the south. The stratigraphic succession and sediment provenance of the foreland basin imply that the early Mianlue oceanic basin, magmatic arc, and nonmarine molasse foreland basin during the period of deposition were modified or buried by the subsequent continent-continent collision between the North China-Qinling-Dabieshan plate and the Yangtze plate during the Jurassic, which followed the oblique amalgamation between these plates during the Middle-Late Triassic.

    Since the end of the Little Ice Age around 1850, the total glacier area of the central European Alps has considerably decreased. In order to understand the changes in glacier coverage at various scales and to model past and future streamflow accurately, long-term and large-scale datasets of glacier outlines are needed. To fill the gap between the morphologically reconstructed glacier outlines from the moraine extent corresponding to the time period around 1850 and the first complete dataset of glacier areas in the Swiss Alps from aerial photographs in 1973, glacier areas from 80 sheets of a historical topographic map (the Siegfried map) were manually digitized for the publication years 1878-1918 (further called first period, with most sheets being published around 1900) and 1917-1944 (further called second period, with most sheets being published around 1935). The accuracy of the digitized glacier areas was then assessed through a two-step validation process: the data were (1) visually and (2) quantitatively compared to glacier area datasets of the years 1850, 1973, 2003, and 2010, which were derived from different sources, at the large scale, basin scale, and locally. The validation showed that at least 70 % of the digitized glaciers were comparable to the outlines from the other datasets and were therefore plausible. Furthermore, the inaccuracy of the manual digitization was found to be less than 5 %. The presented datasets of glacier outlines for the first and second periods are a valuable source of information for long-term glacier mass balance or hydrological modelling in glacierized basins. The uncertainty of the historical topographic maps should be considered during the interpretation of the results. The datasets can be downloaded from the FreiDok plus data repository (https://freidok.uni-freiburg.de/data/15008, https://doi.org/10.6094/UNIFR/15008).

    Large-scale sequencing of prokaryotic genomes demands the automation of certain annotation tasks currently manually performed in the production of the SWISS-PROT protein knowledgebase. The HAMAP project, or 'High-quality Automated and Manual Annotation of microbial Proteomes', aims to integrate manual and automatic annotation methods in order to enhance the speed of the curation process while preserving the quality of the database annotation. Automatic annotation is only applied to entries that belong to manually defined orthologous families and to entries with no identifiable similarities (ORFans). Many checks are enforced in order to prevent the propagation of wrong annotation and to spot problematic cases, which are channelled to manual curation. The results of this annotation are integrated in SWISS-PROT, and a website is provided at http://www.expasy.org/sprot/hamap/.

  17. Swiss-cheese models and the Dyer-Roeder approximation

    Science.gov (United States)

    2014-06-01

    In view of interpreting the cosmological observations precisely, especially when they involve narrow light beams, it is crucial to understand how light propagates in our statistically homogeneous, clumpy, Universe. Among the various approaches to tackle this issue, Swiss-cheese models propose an inhomogeneous spacetime geometry which is an exact solution of Einstein's equation, while the Dyer-Roeder approximation deals with inhomogeneity in an effective way. In this article, we demonstrate that the distance-redshift relation of a certain class of Swiss-cheese models is the same as the one predicted by the Dyer-Roeder approach, at a well-controlled level of approximation. Both methods are therefore equivalent when applied to the interpretation of, e.g., supernova obervations. The proof relies on completely analytical arguments, and is illustrated by numerical results.

  18. No Swiss-cheese universe on the brane

    2005-01-01

    We study the possibility of brane-world generalization of the Einstein-Straus Swiss-cheese cosmological model. We find that the modifications induced by the brane-world scenario are excessively restrictive. At a first glance only the motion of the boundary is modified and the fluid in the exterior region is allowed to have pressure. The general relativistic Einstein-Straus model emerges in the low density limit. However by imposing that the central mass in the Schwarzschild voids is constant, a combination of the junction conditions and modified cosmological evolution leads to the conclusion that the brane is flat. Thus no generic Swiss-cheese universe can exist on the brane. The conclusion is not altered by the introduction of a cosmological constant in the FLRW regions. This shows that although allowed in the low density limit, the Einstein-Straus universe cannot emerge from cosmological evolution in the brane-world scenario

    2010-01-01

    These congress proceedings contain the presentations made at the two-day 8 th Swiss National Photovoltaics Conference held in Winterthur, Switzerland, in February 2010. The presentations were grouped into six sessions. The first session dealt with promotional activities for photovoltaics (PV) in Switzerland. The presentations dealt with the present state of PV promotion, the cantonal support program in Basle and the Swiss photovoltaics market in a global context. The session was rounded off with a podium discussion on the Swiss cost-covering remuneration system for solar power. This theme was looked at in more detail in the second session of the conference; successes and hindrances in the system were discussed as well as an example of an alternative solar power 'exchange'. The third session looked at building-integration of PV systems; facade and roof integration and the use of flexible solar cells were discussed. The second day of the conference featured three further sessions. The first session dealt with transfer of know-how from research institutes to industry. A general overview was presented and specific examples of successful know-how transfer were reported on. The next session dealt with the great challenges presented by the efforts being made to expand the use of PV. Safety aspects were discussed, as were the certified testing of modules, mains integration and the training of personnel involved with the implementation of PV systems. The final session looked at the scenarios, perspectives and visions for Swiss and European PV business. PV systems were examined from the point of view of the semiconductor business, European energy planning, the role of PV in future energy supply and the roles of customers, investors and politics on the way to a renewable future.

    There is increasing evidence that genetic factors are associated with ischemic stroke, including multiple recent reports of association with the gene PDE4D, encoding phosphodiesterase 4D, on chromosome 5q12. Genetic studies of stroke are important but can be logistically difficult to perform. This article reviews the design of the Siblings With Ischemic Stroke Study (SWISS) and discusses problems in performing a sibling-based pedigree study where proband-initiated consent is used to enroll pe...

  6. Light-cone averages in a Swiss-cheese universe

    International Nuclear Information System (INIS)

    Marra, Valerio; Kolb, Edward W.; Matarrese, Sabino

    2008-01-01

    We analyze a toy Swiss-cheese cosmological model to study the averaging problem. In our Swiss-cheese model, the cheese is a spatially flat, matter only, Friedmann-Robertson-Walker solution (i.e., the Einstein-de Sitter model), and the holes are constructed from a Lemaitre-Tolman-Bondi solution of Einstein's equations. We study the propagation of photons in the Swiss-cheese model, and find a phenomenological homogeneous model to describe observables. Following a fitting procedure based on light-cone averages, we find that the expansion scalar is unaffected by the inhomogeneities (i.e., the phenomenological homogeneous model is the cheese model). This is because of the spherical symmetry of the model; it is unclear whether the expansion scalar will be affected by nonspherical voids. However, the light-cone average of the density as a function of redshift is affected by inhomogeneities. The effect arises because, as the universe evolves, a photon spends more and more time in the (large) voids than in the (thin) high-density structures. The phenomenological homogeneous model describing the light-cone average of the density is similar to the ΛCDM concordance model. It is interesting that, although the sole source in the Swiss-cheese model is matter, the phenomenological homogeneous model behaves as if it has a dark-energy component. Finally, we study how the equation of state of the phenomenological homogeneous model depends on the size of the inhomogeneities, and find that the equation-of-state parameters w 0 and w a follow a power-law dependence with a scaling exponent equal to unity. That is, the equation of state depends linearly on the distance the photon travels through voids. We conclude that, within our toy model, the holes must have a present size of about 250 Mpc to be able to mimic the concordance model

    2016-11-01

    This is a retrospective analysis of total serum 25-hydroxyvitamin D (25[OH]D) in Swiss elite wheelchair athletes. The aim was to investigate the occurrence of vitamin D deficiency in Swiss elite wheelchair athletes over the whole year and to detect differences between winter and summer months, and between indoor and outdoor athletes. This study was conducted in Switzerland. A total of 164 blood samples from 72 Swiss elite wheelchair athletes (mean±s.d.: age 32±13 years) were analyzed for total serum 25[OH]D. All participants were members of the national team in their discipline. The following disciplines have been included: rugby, athletics, cycling, tennis, ski alpine, curling and basketball. According to general guidelines, insufficient vitamin D status was defined between 50 and 75 nmol l -1 , deficiency below 50 nmol l -1 and severe deficiency below 27.5 nmol l -1 . In all, 73.2% of all samples showed an insufficiency/deficiency in vitamin D status. Total serum 25[OH]D was significantly higher during summer compared with winter months (69.5±21.4 nmol l -1 vs 51.5±21.9 nmol l -1 ; Pathletes. Conclusively, we recommend supplementation with vitamin D-especially during winter-to prevent a deficiency and an impairment of performance.

  10. Swiss popular initiative for a single health insurer… once again!

    De Pietro, Carlo; Crivelli, Luca

    2015-07-01

    The article describes a recent Swiss popular initiative, aiming to replace the current system of statutory health insurance run by 61 competing private insurers with a new system run by a single public insurer. Despite the rejection of the initiative by 62% of voters in late September 2014, the campaign and ballot results are interesting because they show the importance of (effective) public communication in shaping the outcome of a popular ballot. The relevance of the Swiss case goes beyond the peculiarities of its federalism and direct democracy and might be useful for other countries debating the pros and cons of national unitary health insurance systems versus models using multiple insurers. After this electoral ballot, the project to establish a public sickness fund in Switzerland seems definitely stopped, at least for the next decade. Insurers, who opposed the initiative, have effectively fed the "fear of change" of the population and have stressed the good outcomes of the Swiss healthcare system. However, the political pressure favoured by the popular initiative opened a "windows of opportunity" and led the federal Parliament to pass a stricter regulation of health insurers, improving in this way the current system.

    This article describes the authors' first experience using the EMS Swiss LithoClast pneumatic lithotriptor in the management of middle and distal ureteral calculi. Also presented is a review of the literature comparing different modalities of intracorporeal lithotripsy. A retrospective analysis was performed on 11 patients treated with the Swiss LithoClast using the Circon ACMI MR6 Rigid Mini-ureteroscope (7 patients with distal calculi and 4 patients with midureteral calculi). The lithotriptor successfully fragmented 91% of the calculi, independent of stone composition. Complete failure of fragmentation was only encountered in one patient, and this was secondary to the lithotriptor's inherent ballistic force causing retrograde passage of the calculus. One patient had postoperative radiographic evidence of stone fragments along the ureteral stent. There was no intraoperative morbidity or long-term complications encountered with use of the pneumatic lithotriptor. Additionally, patients' overall satisfaction was 91% with respect to the procedure itself and relief of preoperative pain. The only significant postoperative complaint was ureteral stent discomfort in one patient. The authors conclude that the EMS Swiss LithoClast pneumatic lithotriptor is a safe and effective tool in the management of middle and distal ureteral calculi. However, as noted with one patient, there is always a risk of stone push from the ballistic force of the lithotriptor.

    Full Text Available The North Yellow Sea Basin is a Mesozoic and Cenozoic basin. Based on basin-margin facies, sedimentary thinning, size and shape of the basin and vitrinite reflectance, North Yellow Sea Basin is not a residual basin. Analysis of the development of the basin’s three structural layers, self-contained petroleum systems, boundary fault activity, migration of the Mesozoic–Cenozoic sedimentation centers, different basin structures formed during different periods, and superposition of a two-stage extended basin and one-stage depression basin, the North Yellow Sea Basin is recognized as a superimposed basin.

    2010-01-01

    This article takes a look at the results of a study elaborated for the Swiss Federal Office of Energy. The study comes to the conclusion that the Swiss economy can profit from the implementation of energy-efficiency measures as well as from global growth in the area of products for increasing energy-efficiency. Swiss companies can therefore not only help lower emission rates for greenhouse gases and increase energy efficiency but also create new jobs. The long-term potential for the reduction of CO 2 emissions is quoted as being enormous. Winners and losers in the changing energy scene are noted and opportunities for Swiss exports are examined

    2017-12-01

    In contrast to the internal zones of orogens, where the stacking of thrust sheets can overwhelm more subtle signals, foreland basins can record long-wavelength subsidence or uplift signals caused by mantle processes. We use a new and extensive compilation of geological and thermochronology data from the North Alpine Foreland Basin to understand the dynamics of foreland basins and their interaction with surface and geodynamic processes. We quantify cooling and exhumation rates in the basin by combining published and new vitrinite reflectance, apatite fission track and U-Th/He data with a new inverse burial and thermal history model, pybasin. No correlation is obvious between inferred cooling and exhumation rates and elevation, relief or tectonics. Uncertainty analysis shows that thermochronometers can be explained by cooling starting as early as the Miocene or as late as the Pleistocene. We compare derived temperature histories to exhumation estimates based on the retro-deformation of Molasse basin and the Jura mountains, and to exhumation caused by drainage reorganization and incision. Drainage reorganization can explain at most 25% of the observed cooling rates in the basin. Tectonic transport of the basin's sediments over the inclined basement of the alpine foreland as the Jura mountains shortened can explain part of the cooling signal in the western part of the basin. However, overall a substantial amount of cooling and exhumation remains unexplained by known tectonic and surface processes. Our results document basin wide exhumation that may be related to slab roll-back or other lithospheric processes. We suggest that new (U-Th)/He data from key areas close to the Alpine front may provide better constraints on the timing of exhumation.

    The up-flow anaerobic sludge blanket (UASB) reactor is a promising method for the treatment of high-strength industrial wastewaters due to advantage of its high treatment capacity and settleable suspended biomass retention. Molasses wastewater as a sugar-rich waste is one of the most valuable raw material for bioenergy production due to its high organic strength and bioavailability. Interpretation for complex interactions of microbial community structures and operational parameters can help to establish stable biogas production. RNA-based approach for biogas production systems is recommended for analysis of functionally active community members which are significantly underestimated. In this study, methane production and active microbial community were characterized in an UASB reactor using molasses wastewater as feedstock. The UASB reactor achieved a stable process performance at an organic loading rate of 1.7~13.8-g chemical oxygen demand (COD,·L(-1) day(-1); 87-95 % COD removal efficiencies), and the maximum methane production rate was 4.01 L-CH4·at 13.8 g-COD L(-1) day(-1). Lactococcus and Methanosaeta were comprised up to 84 and 80 % of the active bacterial and archaeal communities, respectively. Network analysis of reactor performance and microbial community revealed that Lactococcus and Methanosaeta were network hub nodes and positively correlated each other. In addition, they were positively correlated with methane production and organic loading rate, and they shared the other microbial hub nodes as neighbors. The results indicate that the close association between Lactococcus and Methanosaeta is responsible for the stable production of methane in the UASB reactor using molasses wastewater.

    Full Text Available The objective of this study was to evaluate the effects of molasses and propionic acid on the fermentation quality and aerobic stability of total mixed ration (TMR silages prepared with whole-plant corn in Tibet. TMR (354 g/kg DM was ensiled with four different treatments: no additive (control, molasses (M, propionic acid (P, and molasses+propionic acid (PM, in laboratory silos (250 mL and fermented for 45 d. Silos were opened and silages were subjected to an aerobic stability test for 12 days, in which chemical and microbiological parameters of TMR silages were measured to determined the aerobic deterioration. After 45 d of ensiling, the four TMR silages were of good quality with low pH value and ammonia/total N (AN, and high lactic acid (LA content and V-scores. M silage showed the highest (p105 cfu/g FM, however, it appeared to be more stable as indicated by a delayed pH value increase. P and PM silages showed fewer yeasts (<105 cfu/g FM (p<0.05 and were more stable than the control and M silages during aerobic exposure. It was concluded that M application increased LA content and improved aerobic stability of TMR silage prepared with whole-plant corn in Tibet. P application inhibited lactic acid production during ensiling, and apparently preserved available sugars which stimulated large increases in lactic acid during aerobic exposure stage, which resulted in greater aerobic stability of TMR silage.

    In Switzerland, the national accident insurance company registered a total of 42 262 soccer injuries, resulting in costs of approximately 145 million Swiss francs (~US$130 million) in 2003. Research on injury prevention has shown that exercise-based programs can reduce the incidence of soccer injuries. This study was conducted to assess the implementation and effects of a countrywide campaign to reduce the incidence of soccer injuries in Swiss amateur players. Cohort study; Level of evidence, 3. All coaches of the Schweizerischer Fussballverband (SFV) received information material and were instructed to implement the injury prevention program "The 11" in their training of amateur players. After the instruction, the coaches were asked to rate the quality and the feasibility of "The 11." Before the start of the intervention and 4 years later, a representative sample of about 1000 Swiss soccer coaches were interviewed about the frequency and characteristics of injuries in their teams. Teams that did or did not practice "The 11" were compared with respect to the incidence of soccer injuries. A total of 5549 coaches for amateur players were instructed to perform "The 11" in the training with their teams. The ratings of the teaching session and the prevention program were overall very positive. In 2008, 80% of all SFV coaches knew the prevention campaign "The 11" and 57% performed the program or most parts of it. Teams performing "The 11" had an 11.5% lower incidence of match injuries and a 25.3% lower incidence of training injuries than other teams; noncontact injuries in particular were prevented by the program. "The 11" was successfully implemented in a countrywide campaign and proved effective in reducing soccer injuries in amateur players. An effect of the prevention program was also observed in the population-based insurance data and health-care costs.

    2015-01-01

    In Switzerland, a new site selection procedure is being implemented since 2008. This procedure, which is laid down in a 'sectoral plan', shows strong elements of public participation and transparency and can be considered a step away from the classical 'decide-announce-defend' approach in decision-making. This procedure tends towards a more governance-oriented approach based on ideas of 'civility' of decision-making. Despite this renewal, the Swiss case clearly shows that any kind of selection process has to be considered as a 'working compromise', which needs to be adapted when new challenges emerge.

    2008-05-01

    This study explores the effects of hillslope mass failure on the sediment flux in the Waldemme drainage basin, Central Swiss Alps, over decadal time scales. This area is characterized by abundant landslides affecting principally flysch units and is therefore an important sediment source. The analysis concentrates on the Schimbrig landslide that potentially contributes up to 15% to the sediment budget of the Waldemme drainage basin. Volumetric changes are quantified using high-resolution elevation models that were extracted using digital photogrammetric techniques. Sediment discharge data were used to constrain the significance of the landslide for sediment flux in the channel network. The temporal extent of the photogrammetric analysis ranges from 1962 to 1998, including an earth slide event in 1994. The analyses reveal that during periods of low slip rates of the landslide, nearly all of the displaced sediments were eroded and supplied to the channel network. In contrast, during active periods, only a fraction of the displaced landslide mass was exported to the trunk stream. Interestingly, the 1994 earth slide event did not disturb the long-term sediment discharge pattern of the channel network, nor did it influence the sediment flux at a weekly scale. However, suspended sediment pulses correlate with higher-than-average precipitation events. This was especially the case in August 2005 when a storm event (> 100 years return period) triggered several debris flows and earth flows in the whole drainage basin and in the Schimbrig area. This storm did not result in a significant increase in the slip rates of the entire landslide's main body. It is therefore proposed that debris flows and earth flows perform the connectivity between hillslope processes (e.g. landsliding) and the trunk stream during and between phases of landslide activity in this particular setting.

    Prabhat Singh

    Full Text Available Apigenin, a dietary flavonoid, is reported to have several therapeutic effects in different diseases including cancer. Toxicity of Apigenin is however, least explored, and reports are scanty in literature. This warrants dose-specific evaluation of toxicity in vivo. In the present study, Apigenin was administered intraperitoneally to Swiss mice at doses of 25, 50, 100 and 200 mg/kg. Serum levels of alanine amino transferase (ALT, aspartate amino transferase (AST and alkaline phosphatase (ALP were measured along with the examination of liver histology, reactive oxygen species (ROS in blood, lipid peroxidation (LPO, glutathione level, superoxide dismutase activity, catalase activity, glutathione S-transferase activity and gene expression in liver tissue. Increase in ALT, AST, ALP, ROS, ratio of oxidized to reduced glutathione (GSSG/GSH and LPO, altered enzyme activities along with damaged histoarchitecture in the liver of 100 or 200 mg/kg Apigenin treated animals were found. Microarray analysis revealed the differential expression of genes that correspond to different biologically relevant pathways including oxidative stress and apoptosis. In conclusion, these results suggested the oxidative stress induced liver damage which may be due to the regulation of multiple genes by Apigenin at higher doses in Swiss mice.

    Certain dietary constituents can induce toxicity and play a critical role in the development of several hepatic disorders. Tartrazine, metanil yellow and sunset yellow are widely used azo dyes in food products, so the present study is aimed to investigate the food color induced hepatotoxicity in Swiss albino rats. Swiss albino rats were divided into four groups, each group having six animals. Group I served as control, Group II, Group III and Group IV were administered with 25, 50 and 75 mg/kg body weight blend of sunset yellow, metanil yellow and tartrazine for 30 days. Hepatotoxicity in rats treated with a blend of these food colors was studied by assessing parameters such as serum total protein, serum albumin, serum alkaline phosphatase (ALP) as well as hepatic malondialdehyde (MDA). The activity of superoxide dismutase (SOD), reduced glutathione (GSH) and catalase (CAT) were assessed. Significantly increased concentrations of serum total protein, serum albumin, serum ALP and hepatic MDA and significantly lowered levels of SOD, reduced GSH and CAT in the liver tissue of treated animals were observed when compared with control animals. The alteration in the liver includes necrosis of hepatocytes, infiltration and vacuolation. The result indicates that consumption of food color in diet induces liver tissue damage. The used doses of food color were mostly attributable to hepatocellular damage and drastic alteration in antioxidant defense system.

    The ZyTemp TN9 is a mass-produced thermal infrared (TIR) sensor that is normally used to build handheld non-contact thermometers. The measurement principle of the TN9 is similar to that of very costly meteorological pyrgeometers. The costs of the TN9 are less than 10. The output of the TN9 consists of observed thermal radiation, the temperature of the measurement instrument, and the emissivity used. The output is provided through a Serial Peripheral Interface protocol. The TN9 was combined with an Arduino board that registered data onto a USB memory stick. A solar cell, lead acid battery, housing and stand completed the meausrement set up. Total costs per set was in the order of 200 Land surface atmosphere interactions in mountainous areas, such as the Swiss Alps, are spatially heterogeneous. Shading, multi-layer cloud formation, and up- and downdrafts make for a very dynamic exchange of mass and energy along and across slopes. In order to better understand these exchanges, the Swiss Slope Experiment at La Fouly (SELF) has built a distributed sensing network consisting of eight micro-met stations and two flux towers in the "La Fouly" watershed in the upper Alps. To obtain a better handle on surface temperature, fifteen TIR sensing stations were installed that made observations during the 2010 Summer. Methods and results will be presented.

    Background Placebo interventions can have meaningful effects for patients. However, little is known about the circumstances of their use in clinical practice. We aimed to investigate to what extent and in which way Swiss primary care providers use placebo interventions. Furthermore we explored their ideas about the ethical and legal issues involved. Methods 599 questionnaires were sent to general practitioners (GPs) and paediatricians in private practice in the Canton of Zurich in Switzerland. To allow for subgroup analysis GPs in urban, suburban, and rural areas as well as paediatricians were selected in an even ratio. Results 233 questionnaires were completed (response rate 47%). 28% of participants reported that they never used placebo interventions. More participants used impure placebos therapeutically than pure placebos (57% versus 17%, McNemar's χ2 = 78, p placebo prescription. Placebo use was communicated to patients mostly as being "a drug or a therapy" (64%). The most frequently chosen ethical premise was that they "can be used as long as the physician and the patient work together in partnership" (60% for pure and 75% for impure placebos, McNemar's χ2 = 12, p placebos. Conclusion The data obtained from Swiss primary care providers reflect a broad variety of views about placebo interventions as well as a widespread uncertainty regarding their legitimacy. Primary care providers seem to preferentially use impure as compared to pure placebos in their daily practice. An intense debate is required on appropriate standards regarding the clinical use of placebo interventions among medical professionals. PMID:19664267

    For the purpose of emergency planning and preparedness, realistic reference scenarios and corresponding accident source terms have been defined on the basis of common plant features. Three types of representative reference scenarios encompass the accident sequences expected to be the most probable. Accident source terms are assumed to be identical for all Swiss nuclear power plants, although the plants differ in reactor type and power. Plant-specific probabilistic safety analyses were used to justify the reference scenarios and the postulated accident source terms. From the full spectrum of release categories available, those categories were selected which would be covered by the releases and time frames assumed in the reference scenarios. For each nuclear power plant, the cumulative frequency of accident sequences not covered by the reference scenarios was determined. It was found that the cumulative frequency for such accident sequences does not exceed about 1 x 10{sup -6} per year. The Swiss Federal Nuclear Safety Inspectorate concludes that the postulated accident source terms for the reference scenarios are consistent with the current international approach in emergency planning, where one should concentrate on the most probable accident sequences.

    Full Text Available Background: Different parts of Allamanda neriifolia (AN, Crinum latifolium (CL, and Bruguiera cylindrical (BC are used in folk medicine to treat diarrhea. Therefore, the aim of this study was to investigate and compare possible antidiarrheal activity of methanol extracts from barks, stems, and roots of AL, CL, and BC in Swiss albino mice. Methods: Antidiarrheal activities of extracts were evaluated at three doses (100mg/kg, 200 mg/kg and 400mg/kg and compared with Loperamide in a castor oil-induced diarrhea and charcoal meal test model in the Swiss albino mice. Results: The aqueous extract of CL and BC administered at doses of 100, 200 and 400mg/kg showed 0%, 24.5%, 62.26% and 5.66%, 37.11%, and 62.26% diarrhea inhibition, respectively (Table 2. This reduction in diarrheal episodes is significant, and maximum effect was observed at the dose of 400mg/kg similarly in the alcohol extracts of both CL and BC. AN administered at the dose of 100, 200 and 400mg/kg showed 55.97%, 74.84% and 74.84% diarrhea inhibition, respectively. Conclusion: The antidiarrheal effect of the AN extract, in contrast to CL and BC, against the castor oil-induced diarrhea model prove its efficacy in an extensive range of diarrheal conditions.

    During two extended summer seasons in 2006 and 2007, we installed two battery driven versions of the Caltech active strand cloud water collector (MiniCASCC) at the Niesen mountain in the northern Swiss Alps. Along, we measured air temperature, relative humidity, wind, and visibility. During these two field operation phases we gained weekly samples of fogwater, where we analysed the major anions and cations, and the stable water isotopes δD and δ18O. The fog collectors were installed at an altitude of 2300 and 1600 m asl to resolve altitudinal differences in fog chemistry. We found a large variability between the events, but no clear altitudinal gradient. At both sites, the most important ions were nitrate, ammonium, and sulphate. Higher concentrations occured preferably in late spring (start of sampling period) and in autumn (end of sampling). Compared to previous studies at lower elevations in the Swiss Plateau during wintertime, our measurements showed considerable lower ion loads in the fogwater. The combination of these results suggest that lowest ion loads are found in convective clouds with a short lifetime and that the highest ion loads occur during radiation fog events at lower elevations.

    An aqueous filtered molasses concentrate (FMC) sourced from sugar cane was used as a functional ingredient in a range of carbohydrate-containing foods to reduce glycaemic response. When compared to untreated controls, postprandial glucose responses in the test products were reduced 5-20%, assessed by accredited glycaemic index (GI) testing. The reduction in glucose response in the test foods was dose-dependent and directly proportional to the ratio of FMC added to the amount of available carbohydrate in the test products. The insulin response to the foods was also reduced with FMC addition as compared to untreated controls. Inclusion of FMC in test foods did not replace any formulation ingredients; it was incorporated as an additional ingredient to existing formulations. Filtered molasses concentrate, made by a proprietary and patented process, contains many naturally occurring compounds. Some of the identified compounds are known to influence carbohydrate metabolism, and include phenolic compounds, minerals and organic acids. FMC, sourced from a by-product of sugar cane processing, shows potential as a natural functional ingredient capable of modifying carbohydrate metabolism and contributing to GI reduction of processed foods and beverages.

    A MIMO (multiple inputs and multiple outputs) fuzzy-logic-based model was developed to predict biogas and methane production rates in a pilot-scale 90-L mesophilic up-flow anaerobic sludge blanket (UASB) reactor treating molasses wastewater. Five input variables such as volumetric organic loading rate (OLR), volumetric total chemical oxygen demand (TCOD) removal rate (R V ), influent alkalinity, influent pH and effluent pH were fuzzified by the use of an artificial intelligence-based approach. Trapezoidal membership functions with eight levels were conducted for the fuzzy subsets, and a Mamdani-type fuzzy inference system was used to implement a total of 134 rules in the IF-THEN format. The product (prod) and the centre of gravity (COG, centroid) methods were employed as the inference operator and defuzzification methods, respectively. Fuzzy-logic predicted results were compared with the outputs of two exponential non-linear regression models derived in this study. The UASB reactor showed a remarkable performance on the treatment of molasses wastewater, with an average TCOD removal efficiency of 93 (±3)% and an average volumetric TCOD removal rate of 6.87 (±3.93) kg TCOD removed /m 3 -day, respectively. Findings of this study clearly indicated that, compared to non-linear regression models, the proposed MIMO fuzzy-logic-based model produced smaller deviations and exhibited a superior predictive performance on forecasting of both biogas and methane production rates with satisfactory determination coefficients over 0.98.

    Urea molasses multi-nutrient block (UMMB) is a feed supplement and one of the best formulas constructed by the National Nuclear Energy Agency (BATAN). This supplement contains soya bean meal (SBM) and has been developed using different protein sources, such as Enterolobium cyclocarpum (Ec), soya bean waste sauce (SBWs), wheat pollard (WP) and WP bypass protein (WPBp). It has also been developed using medicated block (MB). The objective is to introduce the P-32 tracer for obtaining a new feed supplement, to apply UMMB-SBM on beef cattle for fattening, and to test UMMB-MB on cows in the field. Parameters measured include microbial protein synthesis (MPS) in rumen liquid, daily live weight gain (DLWG), milk production and total count of worm in feces. Statistical analysis used were Latin squares, Student’s t-test, and completely randomized design. The UMMB-SBM was better than UMMB-Ec, UMMB-SBWs, and UMMB-WP, because it was able to increase MPS by up to 205.67%, superior to the other feed supplements (51.01%, 34.04%, and 73.94% respectively). On the other hand, with UMMB-WPBp supplementation, MPS was enhanced by 425.27%. The UMMB-SBM was able to increase DLWG by 0.34, 0.30, 0.38 and 0.36 kg/head/d on Bali cattle, Ongole, Simmental, and Frisian Holstein cross breed respectively. The increase of cost benefit ratio was affected by increasing DLWG. These values were 1:1.89; 1: 1.34; 1:1.45 and 1:1.35 respectively. UMMB-MB-C. aeruginosa and albendazole increased milk production by 4.23% and 46.56%, respectively. In the first communal group, beef cows that received UMMB-MB albendazole were able to increase feed consumption, including dry matter, organic matter, crude protein, and total digestible nutrient, at P<0.05. The second communal group, feed consumption significantly differed from control at P<0.05 on crude protein, and total digestible nutrient. UMMB-MB tends to be effective only for ten days on the total amount of egg worm in feces. (author)

    On the basis of long-time integrated sedimentology, paleogeographic and structural - formation studies covering Pliocene-Anthropogenic sediments of South Caspian Basin (SCB) and design of structural - formation, paleogeographic and catagenetic models applying geophysical studies in the region, the author has interred rift nature on this basin during Pliocene-Anthropogenic stage of its evolution. It is assumed that SCB is intercontinental with absence of continental crust. Evolution of SCR started from Miocene, continental stage of development Lesser and Great Caucasus and Kopetdag. At initial stage of South Caspian rift-graben evolution the crystal uplift of Caucasus, Kopetdag and Talysh organic system took place. Extension forces within their borders caused collapse of central part of South Caspian block. We assumed that at later stage folded blocks of Lesser Caucasus and Talysh on the other hand Alborz and Kopetdagh on the other were moving apart. As a result of these riftogene processes the contemporary structure of SCB Antropogene was formed. Starting from Miocene, subsidence of central part of SCB and later movements of folded blocks of Great and Lesser Caucasus, Talysh and Elbrus occurred along Western Caspian, Sangachal - Ogurcghy deep faults and Turkmenistan thrust. During rift generation within SCB, magmatic troughs emerged in the rift zone - South Absheron, Lower Kura. Enzaly and Western Turkmenistan. Structural-formation studies with application of geophysical data acquired in the region, allow assuming that massive Godina can be considered as interrift horst with large gravity anomaly. Its generation relates to Miocene-Pliocene ages and was formed due to South Caspian riftogenesis. The following are sedimentologic evidences of South Caspian rift basin: a) Avalanche sedimentation and development of large thickness (2.5-3 km/106 years) even within border of Lower Pliocene (Productive Series); b) Morphology of Lower Pliocene molasses formation covering 600

    Full Text Available Abstract Background Although factors associated with the utilisation of bone density measurement (BDM and osteoporosis treatment have been regularly assessed in the US and Canada, they have not been effectively analysed in European countries. This study assessed factors associated with the utilisation of BDM and osteoporosis medication (OM in Switzerland. Methods The Swiss Health Survey 2007 data included self-reported information on BDM and OM for women aged 40 years and older who were living in private households. Multivariable logistic regression analysis was used to identify sociodemographic, socioeconomic, healthcare-related and osteoporosis risk factors associated with BDM and OM utilisation. Results The lifetime prevalence of BDM was 25.6% (95% CI: 24.3-26.9% for women aged 40 years and older. BDM utilisation was associated with most sociodemographic factors, all the socioeconomic and healthcare-related factors, and with major osteoporosis risk factors analysed. The prevalence of current OM was 7.8% (95% CI: 7.0-8.6% and it was associated with some sociodemographic and most healthcare-related factors but only with one socioeconomic factor. Conclusions In Swiss women, ever having had a BDM and current OM were low and utilisation disparities exist according to sociodemographic, socioeconomic and healthcare-related factors. This might foster further health inequalities. The reasons for these findings should be addressed in further studies of the elderly women, including those living in institutions.

    The Swiss Society of Cardiology (SSC) and the Swiss Society of Cardiac and ThoracicVascular Surgery (SSCTVS) have formulated their mutual intent of a close, patient-oriented, and expertise-based collaboration in the Heart Team Paper. The interdisciplinary dialogue between the SSC and SSCTVS reflects an attitude in decision making, which guarantees the best possible therapy for the individual patient. At the same time, it is a cornerstone of optimized process quality, placing individual interests into the background. Evaluation of the correct indication for a treatment is indeed very challenging and almost impossible to verify retrospectively. Quality in this very important health policy process can therefore only be assured by the use of mutually recognized indications, agreed upon by all involved physicians and medical specialties, whereby the capacity of those involved in the process is not important but rather their competence. These two medical societies recognize their responsibility and have incorporated international guidelines as well as specified regulations for Switzerland. Former competitors now form an integrative consulting team able to deliver a comprehensive evaluation for patients. Naturally, implementation rests with the individual caregiver. The Heart Team Paperof the SGK and SGHC, has defined guide boards within which the involved specialists maintain sufficient room to maneuver, and patients have certainty of receiving the best possible therapy they require.

    Data grids constitute the required input form for a variety of applications. Therefore, customers increasingly expect climate services to not only provide measured data, but also grids of these with the required configurations on an operational basis. Currently, MeteoSwiss is establishing a production chain for delivering data grids by subscription directly from the data warehouse in order to meet the demand for precipitation data grids by governmental, business and science customers. The MeteoSwiss data warehouse runs on an Oracle database linked with an ArcGIS Standard edition geodatabase. The grids are produced by Unix-based software written in R called GRIDMCH which extracts the station data from the data warehouse and stores the files in the file system. By scripts, the netcdf-v4 files are imported via an FME interface into the database. Currently daily and monthly deliveries of daily precipitation grids are available from MeteoSwiss with a spatial resolution of 2.2km x 2.2km. These daily delivered grids are a preliminary based on 100 measuring sites whilst the grid of the monthly delivery of daily sums is calculated out of about 430 stations. Crucial for the absorption by the customers is the understanding of and the trust into the new grid product. Clearly stating needs which can be covered by grid products, the customers require a certain lead time to develop applications making use of the particular grid. Therefore, early contacts and a continuous attendance as well as flexibility in adjusting the production process to fulfill emerging customer needs are important during the introduction period. Gridding over complex terrain can lead to temporally elevated uncertainties in certain areas depending on the weather situation and coverage of measurements. Therefore, careful instructions on the quality and use and the possibility to communicate the uncertainties of gridded data proofed to be essential especially to the business and science customers who require

    Controlled laboratory study using a repeated-measures, counterbalanced design. To test the ability of 8 Swiss ball exercises (roll-out, pike, knee-up, skier, hip extension right, hip extension left, decline push-up, and sitting march right) and 2 traditional abdominal exercises (crunch and bent-knee sit-up) on activating core (lumbopelvic hip complex) musculature. Numerous Swiss ball abdominal exercises are employed for core muscle strengthening during training and rehabilitation, but there are minimal data to substantiate the ability of these exercises to recruit core muscles. It is also unknown how core muscle recruitment in many of these Swiss ball exercises compares to core muscle recruitment in traditional abdominal exercises such as the crunch and bent-knee sit-up. A convenience sample of 18 subjects performed 5 repetitions for each exercise. Electromyographic (EMG) data were recorded on the right side for upper and lower rectus abdominis, external and internal oblique, latissimus dorsi, lumbar paraspinals, and rectus femoris, and then normalized using maximum voluntary isometric contractions (MVICs). EMG signals during the roll-out and pike exercises for the upper rectus abdominis (63% and 46% MVIC, respectively), lower rectus abdominis (53% and 55% MVIC, respectively), external oblique (46% and 84% MVIC, respectively), and internal oblique (46% and 56% MVIC, respectively) were significantly greater compared to most other exercises, where EMG signals ranged between 7% to 53% MVIC for the upper rectus abdominis, 7% to 44% MVIC for the lower rectus abdominis, 14% to 73% MVIC for the external oblique, and 16% to 47% MVIC for the internal oblique. The lowest EMG signals were consistently found in the sitting march right exercise. Latissimus dorsi EMG signals were greatest in the pike, knee-up, skier, hip extension right and left, and decline push-up (17%-25% MVIC), and least with the sitting march right, crunch, and bent-knee sit-up exercises (7%-8% MVIC

    Results of the test SWISS-1 and test SWISS-2 are reported. These tests examined the effects of an overlying water pool on high temperature melt interactions with concrete. In both tests, a melt of about 46 kilograms of type 304 stainless steel was formed and deposited onto a 21.6 cm diameter disk of limestone/common sand concrete. The concrete disk was retained within a cast MgO annulus. The molten steel was sustained at a power input of 1.3 to 1.7 Watts/gram by induction heating. In test SWISS-1 a water pool was formed over the melt after about 12 cm of concrete had eroded. In test SWISS-2, the water pool was formed about one minute after melt contacted the concrete and before any significant erosion of concrete could take place. In both tests the water pool was kept below the boiling point. Interactions were sustained for about 40 minutes in the two tests. Concrete erosion rates, concrete temperatures, heat fluxes to the overlying water pool, gas generation rates, and evolved gas compositions during tests SWISS-1 and SWISS-2 are reported. Aerosol generation rates are reported for test SWISS-2. 46 refs., 70 figs., 26 tabs

  14. Liberalization of the Swiss electricity and gas market

    International Nuclear Information System (INIS)

    Cattin, J.

    1999-01-01

    The Swiss government intends to liberalize the electricity and gas market. Competition is to be introduced in the electricity sector first because the European Union is also giving priority to this industry. Moreover, electricity prices in Switzerland are too high. The principle of market liberalization is not contested, but the route to be taken to achieve this goal is a matter of heated controversy. Opinions on the power line network, non-amortizable investments, hydropower plants or the pace of market liberalization still differ too widely. Liberalization of the gas market is also in preparation, but the problems here are less complex. This is because competition already exists on the heating market. In addition, domestic gas prices are not much higher than those charged in other countries. (author)

    In 2013, a nationwide investigation was conducted in Switzerland to establish the population's exposure from medical X rays. A hybrid approach was used combining the Raddose database accessible on-line by the participating practices and the Swiss medical pricing system for hospitals. This study revealed that the average annual number of examinations is 1.2 per inhabitant, and the associated annual effective dose is 1.4 mSv. It also showed that computed tomography is the most irradiating modality and that it delivers 70 % of the total dose. The annual effective dose per inhabitant registered a 17 % increase in 5 y and is comparable with what was recently reported in neighbouring countries. (authors)

    2001-07-01

    With the explosive growth of biological data, the development of new means of data storage was needed. More and more often biological information is no longer published in the conventional way via a publication in a scientific journal, but only deposited into a database. In the last two decades these databases have become essential tools for researchers in biological sciences. Biological databases can be classified according to the type of information they contain. There are basically three types of sequence-related databases (nucleic acid sequences, protein sequences and protein tertiary structures) as well as various specialized data collections. It is important to provide the users of biomolecular databases with a degree of integration between these databases as by nature all of these databases are connected in a scientific sense and each one of them is an important piece to biological complexity. In this review we will highlight our effort in connecting biological information as demonstrated in the SWISS-PROT protein database.

  17. Cost effectiveness at Beznau and other Swiss nuclear stations

    1996-01-01

    Switzerland, with 7 million inhabitants, has the sixth highest per-capita electricity consumption in the world. At present, 40% of electric power is nuclear. The four Swiss nuclear plants have an average capacity factor well above 80%. Total cost per kw.h ranges from 5.4 US-cents for Beznau to 7.1 for Leibstadt. Staffing levels are lower than in other countries, due to the stable and highly skilled work force. The maintenance practice has been one of preventive maintenance. Both steam generators in Beznau-1 were replaced in 1993, and Beznau-2 is scheduled for 2000. Some maintenance is done by contractors. There is practically no technical support from headquarters. Retrofitting mandated by the regulatory authority is a matter of concern, because of its effect on production costs. Possible deregulation of the market for electricity in Europe powers the drive to become more efficient. 3 tabs

  18. Volume expansion of a Swiss-cheese universe

    Kozaki, Hiroshi; Nakao, Ken-ichi

    2002-01-01

    In order to investigate the effect of inhomogeneities on the volume expansion of the universe, we study a modified Swiss-cheese universe model. Since this model is an exact solution of Einstein's equations, we can get insight into the nonlinear dynamics of an inhomogeneous universe from it. We find that inhomogeneities make the volume expansion slower than that of the background Einstein-de Sitter universe when they can be regarded as small fluctuations in the background universe. This result is consistent with the previous studies based on the second order perturbation analysis. On the other hand, if the inhomogeneities cannot be treated as small perturbations, the volume expansion of the universe depends on the type of fluctuations. Although the volume expansion rate approaches the background value asymptotically, the volume itself can be finally arbitrarily smaller than the background one and can be larger than that of the background, but there is an upper bound on it

    2003-01-01

    The Swiss Light Source (SLS) at the Paul Scherrer Institute (PSI) is the most recent 3rd generation light source coming to operation. It consists of a 12- TBA storage ring of 288 m circumference providing 5 nm rad emittance at 2.4 GeV, a novel type of full energy booster synchrotron and a 100 MeV linac. The initial four beamlines cover protein X-ray crystallography (PX), materials science (MS), surface and interface spectroscopy (SIS) and microscopy (SIM). We will review the project history, describe the design concepts of the accelerators and the technical subsystems, and report on the commissioning process and the status of operation by end of 2002.

    2015-08-01

    While assisted suicide (AS) is strictly restricted in many countries, it is not clearly regulated by law in Switzerland. This imbalance leads to an influx of people-'suicide tourists'-coming to Switzerland, mainly to the Canton of Zurich, for the sole purpose of committing suicide. Political debate regarding 'suicide tourism' is taking place in many countries. Swiss medicolegal experts are confronted with these cases almost daily, which prompted our scientific investigation of the phenomenon. The present study has three aims: (1) to determine selected details about AS in the study group (age, gender and country of residence of the suicide tourists, the organisation involved, the ingested substance leading to death and any diseases that were the main reason for AS); (2) to find out the countries from which suicide tourists come and to review existing laws in the top three in order to test the hypothesis that suicide tourism leads to the amendment of existing regulations in foreign countries; and (3) to compare our results with those of earlier studies in Zurich. We did a retrospective data analysis of the Zurich Institute of Legal Medicine database on AS of non-Swiss residents in the last 5 years (2008-2012), and internet research for current legislation and political debate in the three foreign countries most concerned. We analysed 611 cases from 31 countries all over the world. Non-terminal conditions such as neurological and rheumatic diseases are increasing among suicide tourists. The unique phenomenon of suicide tourism in Switzerland may indeed result in the amendment or supplementary guidelines to existing regulations in foreign countries.

    2008-04-01

    A large number of applications using manufactured nanoparticles of less than 100 nm are currently being introduced into industrial processes. There is an urgent need to evaluate the risks of these novel particles to ensure their safe production, handling, use, and disposal. However, today we lack even rudimentary knowledge about type and quantity of industrially used manufactured nanoparticles and the level of exposure in Swiss industry. The goal of this study was to evaluate the use of nanoparticles, the currently implemented safety measures, and the number of potentially exposed workers in all types of industry. To evaluate this, a targeted telephone survey was conducted among health and safety representatives from 197 Swiss companies. The survey showed that nanoparticles are already used in many industrial sectors; not only in companies in the new field of nanotechnology, but also in more traditional sectors, such as paints. Forty-three companies declared to use or produce nanoparticles, and 11 imported and traded with prepackaged goods that contain nanoparticles. The following nanoparticles were found to be used in considerable quantities (> 1000 kg/year per company): Ag, Al-Ox, Fe-Ox, SiO2, TiO2, and ZnO. The median reported quantity of handled nanoparticles was 100 kg/year. The production of cosmetics, food, paints, powders, and the treatment of surfaces used the largest quantities of these nanoparticles. Generally, the safety measures were found to be higher in powder-based than in liquid-based applications. However, the respondents had many open questions about best practices, which points to the need for rapid development of guidelines and protection strategies.

  3. Seismic Software Evaluation at the Swiss Seismological Service

    Clinton, John; Olivieri, Marco; Kaestli, Philipp

    2010-05-01

    The Swiss Seismological Service (SED) has an ongoing responsibility to improve the seismic monitoring capability for Switzerland. This is a crucial issue for a country with a low background seismicity but where a large M6+ earthquake is expected in the next decades. With over 30 stations and station spacing of ~25km, the SED operate one of the densest broadband networks in the world, which is complimented by a similar number of real time strong motion stations. An existing in-house processing software has been operational for the last 15 years, and though well suited for the Swiss setting, including the ability to 1. automatically locate and alert local events and 2. manually relocate events with a nonlinear location algorithm using a 3-D velocity model, the software does not satisfactorily accommodate integration of standard community software tools, nor provide a modern database interface for either station metadata or event parameters. To take advantage of major improvements in software architecture and community tools, we wish to migrate to a community standard solution for data acquisition, automatic and manual processing, and archival. We have been evaluating in detail SeisComp3, a state-of-the-art monitoring system developed by GFZ, as well as Nanometrics Apollo Suite (which uses USGS Hydra at it core for event processing). We present our analysis of the capabilities of each software we have been evaluating. In particular, we focus on the capability of each software to detect and identify small local (>Ml1) as well as large regional events. We discuss our results in terms or location and magnitude accuracy, with particular attention to the specific improvements needed from monitoring systems for improved monitoring of small regions with high quality seismic networks.

  4. Summary of Operating Experience in Swiss Nuclear Power Plants 1999

    International Nuclear Information System (INIS)

    2000-05-01

    The five Swiss nuclear power units produced a net total of 23.6 TWh of electricity in 1999 - not as high as the all-time record (24.45 TWh in 1998), but nonetheless a solid operational performance. The nuclear share in overall electricity production was 35.3%, again lower than the previous year's 40%. In general, plant operation in 1999 was practically as undisturbed and as reliable as in 1998, reflecting the ongoing tradition of careful maintenance that contributes so much to keeping the plants in excellent condition. However, due to exceptional outage activities at Beznau 2 (steam generator replacement) and an unplanned shut-down at Goesgen to replace a hydrogen seal on the main generator, 1999 nuclear production could not match that of the previous year. Also, record hydro power production caused the nuclear share in total electricity production to drop. With the exception of Beznau 2, all refueling and maintenance outages were once again short. The Leibstadt outage lasted 26 days, Goesgen 33 days, Beznau 1 lasted 29 days, Beznau 2 89 days and Muehleberg 27 days. At Goesgen, MOX fuel was loaded for the third time in 1999. Of the 44 freshly-loaded fuel elements, 20 were MOX elements. Non-electrical energy supplies from the Beznau and Goesgen nuclear power plants functioned flawlessly. Beznau fed 143.6 GWh of heat energy into the Refuna district heating system, while Goesgen supplied 169 GWh of process heat to the neighboring Niedergoesgen cardboard factory. At the end of 1999 and the beginning of 2000 all Swiss nuclear units continued to operate flawlessly - notwithstanding the challenges posed by the 'Lothar' storm that hit Western Europe in late December and the so-called Y2K computer bug that threatened to hit shortly afterwards, during the 'millennial' change-over.

    Larissa J Maier

    Full Text Available Pharmacological cognitive enhancement (PCE refers to the nonmedical use of prescription or recreational drugs to enhance cognitive performance. Several concerns about PCE have been raised in the public. The aim of the present study was to investigate students' attitudes toward PCE. Students at three Swiss universities were invited by e-mail to participate in a web-based survey. Of the 29,282 students who were contacted, 3,056 participated. Of these students, 22% indicated that they had used prescription drugs (12% or recreational substances including alcohol (14% at least once for PCE. The use of prescription drugs or recreational substances including alcohol prior to the last exam was reported by 16%. Users of pharmacological cognitive enhancers were more likely to consider PCE fair (24% compared with nonusers (11%. Only a minority of the participants agreed with the nonmedical use of prescription drugs by fellow students when assuming weak (7% or hypothetically strong efficacy and availability to everyone (14%. Two-thirds (68% considered performance that is obtained with PCE less worthy of recognition. Additionally, 80% disagreed that PCE is acceptable in a competitive environment. More than half (64% agreed that PCE in academia is similar to doping in sports. Nearly half (48% claimed that unregulated access to pharmacological cognitive enhancers increases the pressure to engage in PCE and educational inequality (55%. In conclusion, Swiss students' main concerns regarding PCE were related to coercion and fairness. As expected, these concerns were more prevalent among nonusers than among users of pharmacological cognitive enhancers. More balanced information on PCE should be shared with students, and future monitoring of PCE is recommended.

Animals were observed for toxic signs and symptoms after oral administration of MTD of imidacloprid in single dose. The body weights of animals were recorded on alternate day. Animals were sacrificed on 14th day and changes in hematological parameters (Hb, TEC, TLC and DLC and morphometric measurements (length, breadth, thickness and weight of various body organs (heart, liver, spleen, kidney, testis and epididymis were examined. The student's t-test was applied to statistically analyze the results.Results: The MTD of imidacloprid was determined to be 110 mg/kg body weight. The sign and symptoms of acute toxicity were ataxia, rigidity and fasciculation of muscles, protrusion of eye ball and tremors of head. Imidacloprid treatment resulted in decreased body weight gain as compared to the control group. The changes in hematological parameters were not significant between imidacloprid treated and control groups. Also the values of relative organ weights and morphometric measurements of various body organs did not differ significantly between the control and imidacloprid treated animals.Conclusions: MTD of imidacloprid in Swiss albino male mice through oral route was determined for the first time. Study revealed a non-toxic effect of imidacloprid on body weight, relative organs weight, hematological parameters and morphometric measurements of various body organs in mice.

    Full Text Available Among the anthropic activities generating potentially toxic residues are those involved with bovine hide processing (tannery industries. However, knowledge is scant regarding the damage caused to the health of various organisms by tannery waste and studies are rare, especially in mammalian experimental models. This study therefore aimed to evaluate the physical and behavioral effects of the exposure of female Swiss mice to tannery effluent. To accomplish this, for a period of 15 days the animals were fed tannery effluent diluted with water in the following concentrations: 0% (control group, received only potable water, 5% and 10%. The body mass of the animals was evaluated at the beginning and end of the experiment, as well as the daily consumption of water and food. After 15 days of exposure to the effluent, the animals were submitted to the elevated plus maze (predictive of anxiety and the forced swim test (predictive of depression. The treatments did not affect the animals' body mass, either in eating behavior or in consumption of water. However, it was found that the animals that ingested tannery effluent concentrations of 5% and 10% exhibited an anxiolytic (lower level of anxiety, greater percentage of time in the open arms, longer time and frequency in the diving behavior, less time of lurks and less frequency of freezing and an antidepressant effect (more time in climbing behavior and less time of immobility when compared to the control group. It was concluded that the exposure of female Swiss mice to tannery effluents (5% and 10% diluted with water causes behavioral changes, possibly related to the neurotoxicity of this waste, without causing physical changes in the animals.

    Nisin is a safe, approved and commercial bacteriocin that is produced by Lactococcus lactis subsp. lactis. Since lactate accumulation in fermentation medium reduces L. lactis growth and nisin production, Yarrowia lipolytica, a lactate consuming yeast and L. lactis subsp. lactis, were simultaneously cultured in a molasses based medium. Y. lipolytica is not able to consume sucrose as carbon source, but rather consumes lactate and hence decrease lactic acid titer by 10% in the medium.

    Full text: A team of international nuclear safety experts today completed a two-week International Atomic Energy Agency (IAEA) review of the regulatory framework for nuclear safety in Switzerland. The Integrated Regulatory Review Service (IRRS) mission noted good practices in the Swiss system and also made recommendations for the nation's nuclear regulatory authority, the Swiss Federal Nuclear Safety Inspectorate (ENSI). ''Our team developed a good impression of the independent Swiss regulator - ENSI - and the team considered that ENSI deserves particular credit for its actions to improve Swiss safety capability following this year's nuclear accident in Japan,'' said IRRS Team Leader Jean-Christophe Niel of France. The mission's scope covered the Swiss nuclear regulatory framework for all types of nuclear-related activities regulated by ENSI. The mission was conducted from 20 November to 2 December, mainly at ENSI headquarters in Brugg. The team held extensive discussions with ENSI staff and visited many Swiss nuclear facilities. IRRS missions are peer reviews, not inspections or audits, and are conducted at the request of host nations. For the Swiss review, the IAEA assembled a team of 19 international experts from 14 countries. The experts came from Belgium, Brazil, the Czech Republic, Finland, France, Germany, Italy, the Republic of Korea, Norway, Russia, Slovakia, Sweden, the United Kingdom, and the United States. ''The findings of the IRRS mission will help us to further improve our work. That is part of our safety culture,'' said ENSI Director General Hans Wanner. ''As Switzerland argued at international nuclear safety meetings this year for a strengthening of the international monitoring of nuclear power, we will take action to fulfil the recommendations.'' The IRRS team highlighted several good practices of the Swiss regulatory system, including the following: ENSI requires Swiss nuclear operators to back-fit their facilities by continuously upgrading

    This comprehensive article reviews an update made in 2009 by the Swiss Association of Electricity Enterprises VSE on their paper 'Outlook 2006 on Swiss electricity supply for the period up to 2035 / 2050'. The association is of the opinion that the paper can still form the basis for issue-related public discussion on energy-related questions. The Swiss 'four-pillar' strategy - energy efficiency, renewable energy, large power stations and international energy policy - is noted and supported. The special role played by electricity in the Swiss energy mix is discussed and the issue of security of supply is examined. Possible shortages that could occur in the future are discussed, as is the question of carbon dioxide emissions. Economic viability and power prices are discussed. Energy efficiency and power production options are also examined. Combined heat and power, hydropower and nuclear power are examined and, finally, import and export options reviewed

    Full Text Available Financial disasters to hedge funds, bank trading departments and individual speculative traders and investors seem to always occur because of non-diversification in all possible scenarios, being overbet and being hit by a bad scenario. Black swans are the worst type of bad scenario: unexpected and extreme. The Swiss National Bank decision on 15 January 2015 to abandon the 1.20 peg against the Euro was a tremendous blow for many Swiss exporters, but also Swiss and international investors, hedge funds, global macro funds, banks, as well as the Swiss central bank. In this paper, we discuss the causes for this action, the money losers and the few winners, what it means for Switzerland, Europe and the rest of the world, what kinds of trades were lost and how they have been prevented.

    A MIMO (multiple inputs and multiple outputs) fuzzy-logic-based model was developed to predict biogas and methane production rates in a pilot-scale 90-L mesophilic up-flow anaerobic sludge blanket (UASB) reactor treating molasses wastewater. Five input variables such as volumetric organic loading rate (OLR), volumetric total chemical oxygen demand (TCOD) removal rate (R{sub V}), influent alkalinity, influent pH and effluent pH were fuzzified by the use of an artificial intelligence-based approach. Trapezoidal membership functions with eight levels were conducted for the fuzzy subsets, and a Mamdani-type fuzzy inference system was used to implement a total of 134 rules in the IF-THEN format. The product (prod) and the centre of gravity (COG, centroid) methods were employed as the inference operator and defuzzification methods, respectively. Fuzzy-logic predicted results were compared with the outputs of two exponential non-linear regression models derived in this study. The UASB reactor showed a remarkable performance on the treatment of molasses wastewater, with an average TCOD removal efficiency of 93 ({+-}3)% and an average volumetric TCOD removal rate of 6.87 ({+-}3.93) kg TCOD{sub removed}/m{sup 3}-day, respectively. Findings of this study clearly indicated that, compared to non-linear regression models, the proposed MIMO fuzzy-logic-based model produced smaller deviations and exhibited a superior predictive performance on forecasting of both biogas and methane production rates with satisfactory determination coefficients over 0.98.

    The potential of using corn steep liquor powder (CSLP), peanut meal (PM), soybean meal (SM), cotton meal (CM) and urea as the substitute of yeast extract (YE) as the nitrogen source was investigated for producing succinic acid (SA). Actinobacillus succinogenes GXAS137 was used as the fermenting bacterium and sugarcane molasses was used as the main substrate. None of these materials were able to produce SA as high as YE did. The CSLP could still be considered as a feasible and inexpensive alternate for YE as the yield of SA produced using CSLP was second only to the yield of SA obtained by YE. The use of CSLP-PM mixed formulation (CSLP to PM ratio = 2·6) as nitrogen source produced SA up to 59·2 g l(-1) with a productivity of 1·2 g l(-1) h(-1). A batch fermentation using a stirred bioreactor produced up to 60·7 g l(-1) of SA at the same formulation. Fed-batch fermentation that minimized the substrate inhibition produced 64·7 g l(-1) SA. These results suggest that sugarcane molasses supplemented with a mixture of CSLP and PM as the nitrogen source could be used to produce SA more economically using A. succinogenes. Significance and impact of the study: Succinic acid (SA) is commonly used as a platform chemical to produce a number of high value derivatives. Yeast extract (YE) is used as a nitrogen source to produce SA. The high cost of YE is currently the limiting factor for industrial production of SA. This study reports the use of a mixture of corn steep liquor powder (CSLP) and peanut meal (PM) as an inexpensive nitrogen source to substitute YE. The results showed that this CSLP-PM mixed formulation can be used as an effective and economic nitrogen source for the production of SA. © 2015 The Society for Applied Microbiology.

    Operating a climatological station network requires continuous and anticipatory planning for accurate monitoring of climate variability and climate change. Therefore Switzerland has established the Swiss National Basic Climatological Network (Swiss NBCN) which combines the most important climatological stations within the observation network of MeteoSwiss. The stations were selected according to different criteria including the geographical distribution evaluated by means of cluster analysis, the length of the available time series and the embedment into international observation networks. The Swiss NBCN currently consists of 29 climate stations recording different parameters and 46 additional precipitation stations. Historical time series of temperature, precipitation and sunshine duration dating back to the 19th century will be completely digitized and homogenized by a cooperative initiative of MeteoSwiss and the ETH Zurich within the next years. In a first step the newly available and quality controlled maximum temperature series of the Swiss NBCN have been homogenized and analyzed for variability and trends. The presented study shows results from the homogenization process such as reasons and magnitudes of detected inhomogeneities as well as summarized adjustments to illustrate possible systematic biases in the original time series. A trend analysis based on the homogeneous monthly climate series gives an overview of the temporal and spatial variations of maximum temperature evolution in Switzerland from 1864 till today.

    The SWISS-PROT protein knowledgebase (http://www.expasy.org/sprot/ and http://www.ebi.ac.uk/swissprot/) connects amino acid sequences with the current knowledge in the Life Sciences. Each protein entry provides an interdisciplinary overview of relevant information by bringing together experimental results, computed features and sometimes even contradictory conclusions. Detailed expertise that goes beyond the scope of SWISS-PROT is made available via direct links to specialised databases. SWISS-PROT provides annotated entries for all species, but concentrates on the annotation of entries from human (the HPI project) and other model organisms to ensure the presence of high quality annotation for representative members of all protein families. Part of the annotation can be transferred to other family members, as is already done for microbes by the High-quality Automated and Manual Annotation of microbial Proteomes (HAMAP) project. Protein families and groups of proteins are regularly reviewed to keep up with current scientific findings. Complementarily, TrEMBL strives to comprise all protein sequences that are not yet represented in SWISS-PROT, by incorporating a perpetually increasing level of mostly automated annotation. Researchers are welcome to contribute their knowledge to the scientific community by submitting relevant findings to SWISS-PROT at swiss-prot@expasy.org.

  20. Dynamics of thin-skinned fold and thrust belts with a tilted detachment

    2014-05-01

    The formation of the Jura fold and thrust belt is linked to the Alpine orogeny. However, it is still a matter of debate why the Jura was formed tens of kilometres far away from the active deformation front while the Molasse basin that lies in between remained mostly undeformed. Progressive thickening of the Molasse basin due to its infill with sediments, and the existence of a tilted potential detachment level at the Triassic evaporitic units, have been pushed forward as the main causes for the detachment of the Molasse basin and the consequent jump of the deformation front from the Alpine front to the position of the Jura at around 22 Ma or later (e.g Willett and Schlunegger, 2010). In order to better understand the dynamics of a thin-skinned fold and thrust belt with a tilted detachment we have performed systematic forward numerical simulations with the 2D thermo-mechanical finite element code MILAMIN_VEP. The modelled setup consists of a tilted detachment, overlain by a sedimentary cover of constant thickness and a wedge shaped basin infill that makes the initial surface slope of the system to be zero. In this study we have tested the importance of the following factors in the dynamics of such a fold and thrust belt evolution: 1) the applied boundary conditions 2) the angle of a uniformly tilted detachment 3) the end displacement of a curved detachment with a flexural foreland basin profile. The implications of the studied factors are discussed for the case of the Jura-Molasse system.

    This study aims at a first evaluation of the outcome of the Swiss national MD-PhD program during the last 16 years. One hundred and twenty six former and current students in the Swiss national MD-PhD program were surveyed via a Web-based questionnaire in September 2007. Twenty-four questions assessed information regarding participant demographics, information on the PhD thesis and publication activity, current positions and research activity, as well as participant's opinions, attitudes and career goals. Eighty questionnaires were received from 126 MD-PhD students and graduates (63.5% response rate). The responders consisted of present students (36%), former graduates (56%), and dropouts (8%). The percentage of women in the program was 23%, and the average duration of the program was 4.2 +/- 1.4 years. Research interests were predominantly in the fields of neuroscience, immunology, molecular biology and cancer research. A considerable portion of the MD-PhD graduates had an excellent publication record stemming from their PhD research work, and 89% were planning to continue a research-orientated career. Over 50% of those MD-PhD graduates completing their thesis before 2002 had already reached an assistant or full professor position at the time of the survey. Nearly all participants considered the MD-PhD training helpful to their career and high quality standards were assigned to the acquired practical and intellectual skills. However, criticism was expressed concerning the general mentoring and the career related mentoring. Moreover, general mentoring and career related mentoring were significantly less well perceived in research groups employing more than seven PhD students at the same time. The MD-PhD students and graduates surveyed were satisfied with their education and most of them continued a research-orientated career. Regarding the overall positive evaluation, this study supports the view that MD-PhD graduates are well qualified for a successful career in

    The 1998 nationwide survey of the exposure of the Swiss population by medical X-rays indicated that 5.4 million X-ray examinations (dental excluded) were performed annually in Switzerland (762 per 1000 population), leading to an annual collective dose to the population of 7100 Sv and an average annual effective dose of 1.0 mSv/caput. The contribution of conventional radiography was found to be 84% of the total in terms of frequency and 42% in terms of the collective dose. The study showed also that general practitioners (GP) contributed 27% to the total frequency and 9.5% to the collective dose. The present work aimed at assessing the variation over the years of the frequency of radiographies carried out by general practitioners in Switzerland. A sample of 49 general practitioners stratified on the seven Swiss geographic regions was surveyed. A questionnaire was sent to them and they were asked to give the annual number of examinations they performed during 2004, 2005 and 2006 for the 30 types of X-ray types of examinations most commonly used by GPs. The results of the study were compared to the data obtained in earlier surveys: 1998 and 2003. 37 GPs filled in the questionnaire properly (response rate of 76%). In 2006 a GP carried out on average 488 radiographies (about 2 per working day), showing a 4% decrease compared to 2003. The most frequent type of examination is chest radiography with an annual frequency of 133/GP per year, which represents 30% of all radiographies performed by GPs. It is followed by radiographies of the knee (45/GP), the finger (34/GP) and the ankle (34/GP). The most significant change revealed by this investigation is related to chest radiography with a steady decrease from 1998 to 2006 (15.4% fall over a period of 8 years). This is a real trend, in accordance with the results obtained in the 1998 survey, which showed that the frequency of chest radiography dropped by a factor of 2 in twenty years (1978-1998). (author)

    The financing of future decommissioning of the Swiss nuclear power plants and the permanent, safe disposal of the wastes arising therefrom is secured by payments into a legally established decommissioning fund. In order to update the required level of payments into the fund, which have been ongoing since 1984, 20 years after the first study the costs of decommissioning have been re-calculated from scratch using complete decommissioning studies for each plant. Following the specification of boundary conditions which take into account the specific situation in Switzerland, decommissioning concepts are drawn up for the individual plants. The measures outlined in these concepts are integrated into a cost structuring plan and the decommissioning costs are then calculated using standard models (e.g. STILLKO). The radiological inventory, which is re-calculated for each plant, has a significant influence on costs. Furthermore, the disposal costs which can be allocated to decommissioning waste have to be determined; these are based on a concept in which only two types of containers are considered for disposal. The studies have resulted in decommissioning costs which, with a range between 200 and 390 million Euro, are comparable with costs in other countries. (orig.)

    The aim of this study was to compare psychosocial adaptation in adolescent (first generation) migrants, double-citizens (mainly second generation with one migrant parent), and native Swiss, and to compare migrants from various European regions. Data from a community survey were based on 1,239 participants (mean age 13.8, SD = 1.6 years) with 996 natives, 55 double-citizens, and 188 migrants. The adolescents completed the youth self-report measuring emotional and behavioural problems, and various questionnaires addressing life events, personality variables, perceived parental behaviour (PPB), family functioning, school environment, and social network. Adolescent migrants had significantly higher scores for internalizing and externalizing problems. There was a pattern of various unfavourable psychosocial features including life events, coping, self-related cognitions, and PPB that was more common among adolescent migrants than natives. Double-citizens were similar to natives in all domains. Young adolescents from South and South-East Europe differed from natives in terms of more unfavourable psychosocial features. Migrant status was best predicted by adverse psychosocial features rather than emotional and behavioural problems. There is some indication that certain migrant adolescents are at risk of psychosocial mal-adaptation. Obviously, ethnic origin is an important moderator.

    This paper aims at analysing the impact of prospective payment schemes on cost efficiency of acute care hospitals in Switzerland. We study a panel of 121 public hospitals subject to one of four payment schemes. While several hospitals are still reimbursed on a per diem basis for the treatment of patients, most face flat per-case rates-or mixed schemes, which combine both elements of reimbursement. Thus, unlike previous studies, we are able to simultaneously analyse and isolate the cost-efficiency effects of different payment schemes. By means of stochastic frontier analysis, we first estimate a hospital cost frontier. Using the two-stage approach proposed by Battese and Coelli (Empir Econ 20:325-332, 1995), we then analyse the impact of these payment schemes on the cost efficiency of hospitals. Controlling for hospital characteristics, local market conditions in the 26 Swiss states (cantons), and a time trend, we show that, compared to per diem, hospitals which are reimbursed by flat payment schemes perform better in terms of cost efficiency. Our results suggest that mixed schemes create incentives for cost containment as well, although to a lesser extent. In addition, our findings indicate that cost-efficient hospitals are primarily located in cantons with competitive markets, as measured by the Herfindahl-Hirschman index in inpatient care. Furthermore, our econometric model shows that we obtain biased estimates from frontier analysis if we do not account for heteroscedasticity in the inefficiency term.

    The extraction, at the laboratory level, of U and Th from Swiss granites is discussed. The Mittagfluh, Bergell and Rotondo granites and the Giuv syenite offered a wide range of U and Th concentrations; 7.7 to 20.0 ppm U and 25.5 to 67.0 ppm Th. U and Th were determined in the leach solutions by the fission track method and by spectrophotometry, respectively. Samples containing less than 0.3 μg U and 4 μg Th, could be measured with an accuracy of 10% for U and 5% for Th. Leach tests were performed during which the following parameters were varied: granite-type, grain size, acid-type, acid concentration, temperature and time. There were very great leaching differences between the granites studied. Temperature was the most important parameter. Sharp differences in extraction occurred between 20 0 C, 50 0 C and 80 0 C. At 80 0 C, more than 85% U and Th were extracted. The extraction curve (percent extracted as a function of time) of aliquots sampled after 1, 2, 4, 8, 12 and 24 hours showed a plateau after 8 hours. The half life of the reaction was between one and two hours. As a general rule, Th was better extracted than U. (Auth.)

  7. Tritium pollution in the Swiss luminous compound industry

    The Swiss luminous compound industry is an important consumer of tritium. About 350kCi go into production of tritium gas-filled light sources and 40kCi into production of tritium luminous compound annually. To illustrate the pollution problem, a factory is mentioned that handles 200kCi annually and a chain of luminizers, processing 20kCi over the same period as tritium luminous compound. This material is manufactured by coating phosphors with tritiated polystyrene having a specific activity up to 200Ci/g. Because of the high specific activity, the radiation damage produces an average activity release of 5.2% annually, which is one of the main reasons for public and occupational exposure. The processing of large quantities of tritium gas requires special equipment, such as units made entirely of stainless steel for purification and hydrogenation, oxidation systems for highly contaminated air, glove boxes, ventilation and monitoring systems. Nevertheless, contamination of air, surfaces, water and workers cannot be avoided. Only in a few cases were MPC-values for tritium content in urine of workers exceeded. From these results, biological half-lives between 5-15 days were estimated. Regular medical examinations showed no significant influence in blood picture parameters, except in one single case with a tritium concentration in urine of 2.8mCi/litre. Entirely different problems arise in most luminizing factories where luminous paint is processed as an open radioactive source. (author)

    The goal of this study was to describe the development of equine drug testing in horses in Switzerland. This was achieved through evaluation of a film made by the Institute of Forensic Medicine at the University of Basel entitled 'Doping von Rennpferden' [Doping of Race Horses], toxicological detection, 1962', the analysis of doping test results of the Swiss Equestrian Federation and by interviewing individuals of various professions who were involved in equine drug testing at the time. The study compares early and modern methods of drug testing and highlights the changes in the attitude of equestrian athletes, horse owners and the general public toward doping in equestrian sports. The high sensitivity of modern analytical methods allows the detection of drugs at levels considerably below therapeutic concentrations. This has resulted in a shift from zero tolerance for Controlled Medication Substances to the establishment of sub-therapeutic threshold concentrations. The lists of performance-enhancing drugs used in doping are updated continually. It became clear from this work that in the early 1960s, Switzerland played a leadership role in anti-doping in equestrian sports, and that the efforts to keep the sport free of performance-enhancing drugs remain exemplary.

In the biomass combustion area, subjects discussed include system optimisation for automatic firing, combustion particles, low-particle pellet furnaces, design and optimisation of wood-fired storage ovens, efficiency of filtering techniques and methane generation from wood. Also, an accredited testing centre for wood furnaces is mentioned and measurements made on an installation are presented. As far as the fermentation of biogenic wastes is concerned, biogas production from dairy-product wastes is described. Other projects discussed include a study on eco-balances of energy products, certification and marketing of biogas, evaluation of membranes, a measurement campaign for solar sludge-drying, the operation of a percolator installation for the treatment of bio-wastes, the effects of compost on the environment and the fermentation of coffee wastes. Also, statistics on biogas production in 2002 is looked at. Finally, a preliminary study on biofuels is presented.

  10. On cosmological observables in a swiss-cheese universe

    Photon geodesics are calculated in a swiss-cheese model, where the cheese is made of the usual Friedmann-Robertson-Walker solution and the holes are constructed from a Lemaitre-Tolman-Bondi solution of Einstein's equations. The observables on which we focus are the changes in the redshift, in the angular-diameter--distance relation, in the luminosity-distance--redshift relation, and in the corresponding distance modulus. We find that redshift effects are suppressed when the hole is small because of a compensation effect acting on the scale of half a hole resulting from the special case of spherical symmetry. However, we find interesting effects in the calculation of the angular distance: strong evolution of the inhomogeneities (as in the approach to caustic formation) causes the photon path to deviate from that of the FRW case. Therefore, the inhomogeneities are able to partly mimic the effects of a dark-energy component. Our results also suggest that the nonlinear effects of caustic formation in cold dark ma...

  11. Environmental assessment of current and future Swiss electricity supply options

    Options for near future electricity supply are currently one of the main topics in the Swiss energy policy debate. Contrary to the total energy demand per capita the trend of rising electricity demand per capita is still visible. This paper presents a comparative environmental assessment of a broad portfolio of current and future electricity generation technologies including nuclear, fossil, and renewable power plants with their associated energy chains. The evaluation, based on Life Cycle Assessment (LCA), is carried out quantifying ten different environmental indicators, grouped in the categories greenhouse gas emissions, consumption of resources, waste, and impact on ecosystems. Hydropower shows minimal environmental impacts for all indicators; for other systems, the picture is diverse. The comparison of non-aggregated indicators allows preliminary conclusions about the environmental performance of the assessed systems. Establishing ranking of technologies calls for aggregating the indicators, which can be done by weighting of the indicators based on individual or stakeholder group preferences, either within a Multi-Criteria Decision Analysis (MCDA) framework or with Life Cycle Impact Assessment (LCIA) methods. Calculating total costs of electricity by adding external costs due to impacts on human health and ecosystems to the electricity production costs poses another option for ranking of technologies.

  12. Interfaces and interactions in the Swiss waste disposal programme

    1994-01-01

    Switzerland is a small country (41,293 km 2 ) with a small population (∼7 million) and a small nuclear power park (∼3000 MWe) which gives rise to correspondingly limited volumes of radioactive wastes. The following sections present a summary of the technical and organizational structures involved in the procedures for implementing a back-end strategy in Switzerland and the rationale for their choice. The hierarchical organizational units involved in repository projects, their responsibilities and their interactions are described. This linked chain of responsibilities must be thought through as a whole if interface and communication problems in the line structure are to be minimized -- this we call vertical integration. The programme implementers do not work, however, in a technical or social vacuum. Interfaces to other bodies (regulators, politicians, public) are equally vital to programme success. These communications and exchanges must all be coordinated with one another and with the line organization -- this we call horizontal interaction. The multidimensional organizational system to be considered is described in Sections 2 and 3, in which the roles of each of the entities involved and the relevant interfaces are described. Beforehand, however, we present a short overview of the Swiss waste management strategy and the current programme status in order that individual points made in the following discussion can be related to concrete projects, plans, locations and waste management facilities

    Switzerland was among the first countries that adapted its national law to the recommendations of the ICRP-publication No. 60. Already in 1991, the Federal Parliament enacted a new Radiological Protection Act. In 1994, the Federal Government adopted the new Radiation Protection Ordinance. Federal Ministries followed with technical ordinances and guidelines, e.g., for radioactive waste in 1996, for handling open sources in 1997, for X-rays in 1998 and for the training and dosimetry of radiation workers in 1999. In 1996, the Council of the European Union (Switzerland is not a member of the EU) decreed the Directive for the Protection of the Health of Workers and the General Public against the Dangers Arising from Ionising Radiation. Based on this directive, Germany adopted a new Radiation Protection Ordinance in 2001 and a new X-Ray-Ordinance in 2002. To transform the ordinances into radiation protection in the workplace further technical ordinances and guidelines are under development. Almost ten years ago, users of ionising radiation in Switzerland had to deal with the problems of implementing the new radiation protection legislation into their local rules that Germany and other EU companies are facing now. Therefore it may be interesting and helpful for authorities and companies in the EU to learn from the experience of their Swiss colleagues. (Author) 4 refs

  1. Glacial and periglacial "dynamic" geodiversity in a high altitude alpine basin (Hohsand Basin, Italy)

    On high altitudes climate changes interact with glacial processes and dynamics causing important modifications on the alpine morphology. These transformations lead to a gradual evolution of the geosphere and cryosphere. Growing concern of warming-induced permafrost degradation and modifications of geomorphological characteristics of alpine landscapes increases importance of researches on high mountain dynamic geodiversity. Within this framework, work field studies have been carried out in the Hohsand Basin of the Formazza Valley (Lepontine Alps, NW-Italy). This high alpine catchment is characterised by the major alpine glaciated area (even if in strong regression) of the Piemonte Region and by one of the largest hydroelectric reservoir of this area. Climatological studies have been carried out to analyse the local climate, to identify the trends of the main climatic parameters, to verify the existence of climatic conditions for the development of cryotic processes and to investigate the morpho-climatic evolution of the basin since the 1950s. The geomorphological analysis has been conducted in order to describe the landform geodiversity of the basin and to understand the evolution of the recently deglaciated areas with related glacial landforms. The data, derived from photographic interpretation (aerial images of the years 1955, 1977, 1983, 1989, 1999, 2001 and digital orthoimages of the years 1988-1989, 1994-1998, 2000, 2007, 2009, 2010) and field surveys carried out in summer 2012, have been digitized in open source GIS environment. Through these data and methods, morphometric elaborations have been carried out, geomorphological maps (scale 1:10000 and details at 1:3000) and a glacial deposits map (scale 1:25000) of the basin have been also realised. Periglacial micromorphological forms (e.g. patterned ground) have been investigated during detailed field surveys. Periglacial and permafrost landforms have been used for tracing changes in the permafrost distribution

    This study was designed to determine the effect of adding a molasses-based liquid feed (LF) supplement to a high-grain mixed ration on the feed sorting behavior and growth of grain-fed veal calves. Twenty-four Holstein bull veal calves (90.2 ± 2.6 d of age, weighing 137.5 ± 16.9 kg) were split into groups of 4 and exposed, in a crossover design with 35-d periods, to each of 2 treatment diets: 1) control diet (76.0% high-moisture corn, 19.0% protein supplement, and 5.0% alfalfa/grass haylage) and 2) LF diet (68.4% corn, 17.1% protein supplement, 9.0% molasses-based LF, and 4.5% alfalfa/grass haylage). Diets were designed to support 1.5 kg/d of growth. Data were collected for the final 3 wk of each treatment period. Feed intakes were recorded daily and calves were weighed 2 times/wk. Feed samples of fresh feed and refusals were collected 3 times/wk for particle size analysis. The particle size separator had 3 screens (19, 8, and 1.18 mm) and a bottom pan, resulting in 4 fractions (long, medium, short, and fine). Sorting was calculated as the actual intake of each fraction expressed as a percent of its predicted intake. Calves tended ( = 0.08) to sort for long particles on the control diet (110.5%) and did not sort these particles on the LF diet (96.8%). Sorting for medium particles (102.6%) was similar ( = 0.9) across diets. Calves sorted against short particles on the LF diet (97.5%; = 0.04) but did not sort this fraction on the control diet (99.4%). Calves sorted against fine particles (79.3%) to a similar extent ( = 0.2) on both diets. Dry matter intake was similar across diets (6.1 kg/d; = 0.9), but day-to-day variability in DMI was greater (0.5 vs. 0.4 kg/d; = 0.04) when calves were fed the control compared with the LF diet. Calves on both diets had similar ADG (1.6 kg/d; = 0.8) as well as within-pen variability in ADG (0.4 kg/d; = 0.7). The feed-to-gain ratio was also similar between control and LF diets (4.3 vs. 3.9 kg DM/kg gain; = 0.4). The results suggest

    In Switzerland the site selection procedure for both high level waste (HLW) and low and intermediate level waste (L/ILW) repositories is specified by the Swiss Federal Office of Energy in the Sectoral Plan for Deep Geological Repositories. In the forthcoming stage 2 of this plan, potential sites will be identified within regions previously selected based on the presence of suitable host rocks, namely Opalinus Clay, 'Brauner Dogger', Effingen Member and Helvetic Marl. Preliminary safety analyses are an integral part of this procedure, and require, amongst other information, the radionuclide sorption properties of the host rock. This report describes a methodology to develop a Generic Rock Sorption Data Base (GR-SDB) for argillaceous rocks. The method will be used to compile specific SDBs for the above mentioned host rocks. Arguments are presented that the main factor influencing sorption on argillaceous rocks is the phyllosilicate mineral content. These minerals are particularly effective at binding metals to their surfaces by cation exchange and surface complexation. Generally, the magnitude of sorption is directly correlated with the phyllosilicate content (2:1 type clays: illite/smectite/illitesmectite mixed layers), and this parameter best reflects the sorption potential of a given mineral assembly. Consequently, sorption measurements on illite were preferably used as source data for the GR-SDB. The second component influencing radionuclide sorption is the porewater chemistry. In the present report, generic water compositions were extracted from the analytical ranges of deep ground waters in various sedimentary formations in Switzerland. In order to cover the range of ionic strength (I) and pH values of Swiss ground waters in argillaceous rocks, five types of generic water compositions were defined, combining low, intermediate and high values of ionic strength and pH. The GR-SDB for in situ conditions was derived using conversion factors (CF). As the name

    Full text: The radioprotective role of aqueous extract of Adhatoda vesica leaf extract against radiation induced hematological alterations in peripheral blood of Swiss albino mice was studied at various post-irradiation intervals between 6 hrs to 30 days. Oral administration of Adhatoda vesica leaf extract (800 mg / kg body weight) prior to whole-body irradiation showed a significant protection in terms of survival percentage and hematological parameters. Mice exposed to radiation (8 Gy) without Adhatoda vesica leaf extract pre-treatment exhibited signs of radiation sickness like anorexia, lethargicity, ruffled hairs and diarrhoea and such animals died within 26 days post-irradiation. The dose reduction factor (DRF=1.6) for Adhatoda vesica leaf extract was calculated from LD50/30 values. A significant decline in hematological constituents (RBCs, WBCs, Hb and Hct) was evident till day 15, at later period of observation (day 15 onwards), no animals could survive from control group whereas, in Adhatoda vesica leaf extract pre-treated irradiated group, a gradual recovery was noted in the hematological values. However, these hematological values remained significantly below the normal even till day 30. A significant decrease in GSH was recorded in control animals. Experimental animals showed a significant increase in GSH content (blood as well as liver) with respect to control, but such values remained below normal. A significant increase in TBARS level in liver and serum was evident in control animals. Although, no significant difference was noticed in such levels in normal and Adhatoda vesica leaf extract treated animals. But, a significant decrease was registered in Adhatoda vesica leaf extract pretreated irradiated animals. The results from the present study suggest that Adhatoda vesica leaf extract has radioprotective role in stimulating/protecting the hematopoietic system thereby enhancing the survival and increasing the hematological constituents in peripheral

    This study aims at investigating the HLA molecular variation across Switzerland in order to determine possible regional differences, which would be highly relevant to several purposes: optimizing donor recruitment strategies in hematopoietic stem cell transplantation (HSCT), providing reliable reference data in HLA and disease association studies, and understanding the population genetic background(s) of this culturally heterogeneous country. HLA molecular data of more than 20,000 HSCT donors from 9–13 recruitment centers of the whole country were analyzed. Allele and haplotype frequencies were estimated by using new computer tools adapted to the heterogeneity and ambiguity of the data. Non-parametric and resampling statistical tests were performed to assess Hardy-Weinberg equilibrium, selective neutrality and linkage disequilibrium among different loci, both in each recruitment center and in the whole national registry. Genetic variation was explored through genetic distance and hierarchical analysis of variance taking into account both geographic and linguistic subdivisions in Switzerland. The results indicate a heterogeneous genetic makeup of the Swiss population: first, allele frequencies estimated on the whole national registry strongly deviate from Hardy-Weinberg equilibrium, by contrast with the results obtained for individual centers; second, a pronounced differentiation is observed for Ticino, Graubünden, and, to a lesser extent, Wallis, suggesting that the Alps represent(ed) a barrier to gene flow; finally, although cultural (linguistic) boundaries do not represent a main genetic differentiation factor in Switzerland, the genetic relatedness between population from south-eastern Switzerland and Italy agrees with historical and linguistic data. Overall, this study justifies the maintenance of a decentralized donor recruitment structure in Switzerland allowing increasing the genetic diversity of the national—and hence global—donor registry.

    The Global Initiative for Asthma (GINA) is a network of individuals, organizations, and public health officials that was established to disseminate information about the care of patients with asthma and to improve asthma care. The GINA ("Global Strategy for Asthma Management and Prevention") report has been updated annually since 2002. Due to new knowledge and therapeutic development in the field, the Swiss Respiratory Society felt the need to provide a new document that is based on both the available literature and the recommendations of the 2016 GINA report. Key new features of the 2016 GINA report include a "new" definition of asthma, underscoring its heterogeneous nature, and the core elements of variable symptoms and variable expiratory airflow limitation; the importance of confirming the diagnosis of asthma in order to minimize both under- and overtreatment; practical tools for the assessment of symptom control and risk factors for adverse outcomes; a comprehensive approach to asthma management that acknowledges the foundational role of inhaled corticosteroid therapy, but also provides a framework for individualizing patient care; an emphasis on maximizing the benefit of available medications by addressing common problems such as incorrect inhaler technique and poor adherence; a continuum of care for worsening asthma, starting with early self-management and progressing to primary care or acute care management; and diagnosis of the asthma/chronic obstructive pulmonary disease overlap syndrome. This document is meant to advice the key stakeholders on the diagnosis and management of asthma and highlights the need to individualize the care of each and every asthmatic patient. © 2018 S.

  8. Hawking radiation in the Swiss-cheese universe

    Saida, Hiromi

    2002-01-01

    The Hawking radiation forms the essential basis of black-hole thermodynamics. Black-hole thermodynamics denotes a good correspondence between black-hole kinematics and the laws of ordinary thermodynamics, but has so far been considered only in an asymptotically flat case. Does such correspondence rely strongly on the feature of gravity vanishing at infinity? In order to resolve this question, extending the Hawking radiation to a case with a dynamical boundary condition like an expanding universe should be considered. Therefore, the Hawking radiation in an expanding universe is discussed in this paper. As a concrete model of a black hole in an expanding universe, we use the 'Swiss-cheese' universe which is a spacetime including a Schwarzschild black hole in the Friedmann-Robertson-Walker universe. Further, for simplicity, our calculation is performed in two dimensions. The resultant spectrum of the Hawking radiation measured by a comoving observer is generally different from a thermal one. We find that the qualitative behaviour of the non-thermal spectrum is of dumping oscillation as a function of the frequency measured by the observer, and that the intensity of the Hawking radiation is enhanced by the presence of a cosmological expansion. It is appropriate to say that a black hole with an asymptotically flat boundary condition stays in a lowest energy thermal equilibrium state, and that once a black hole is put into an expanding universe, it is excited to a non-equilibrium state and emits its mass energy with stronger intensity than a thermal one

    Antimicrobial resistance is an emerging concern to public health, and food-producing animals are known to be a potential source for transmission of resistant bacteria to humans. As legislation of the European Union requires to ban conventional cages for the housing of laying hens on the one hand, and a high food safety standard for eggs on the other hand, further investigations about the occurrence of antimicrobial resistance in alternative housing types are required. In this study, we determined antimicrobial resistance in indicator bacteria from 396 cloacal swabs from 99 Swiss laying hen farms among four alternative housing types during a cross-sectional study. On each farm, four hens were sampled and exposure to potential risk factors was identified with a questionnaire. The minimal inhibitory concentration was determined using broth microdilution in Escherichia coli (n=371) for 18 antimicrobials and in Enterococcus faecalis (n=138) and Enterococcus faecium (n=153) for 16 antimicrobials. All antimicrobial classes recommended by the European Food Safety Authority for E. coli and enterococci were included in the resistance profile. Sixty per cent of the E. coli isolates were susceptible to all of the considered antimicrobials and 30% were resistant to at least two antimicrobials. In E. faecalis, 33% of the strains were susceptible to all tested antimicrobials and 40% were resistant to two or more antimicrobials, whereas in E. faecium these figures were 14% and 39% respectively. Risk factor analyses were carried out for bacteria species and antimicrobials with a prevalence of resistance between 15% and 85%. In these analyses, none of the considered housing and management factors showed a consistent association with the prevalence of resistance for more than two combinations of bacteria and antimicrobial. Therefore we conclude that the impact of the considered housing and management practices on the egg producing farms on resistance in laying hens is low. © 2010

    Full Text Available In the following article the author covers the process of counting the votes and the disclosure rules of establishment the election results in the Swiss Confederation. Switzerland along with other EU member states pays special attention to the determination of the election results. According to Art. 149 para. 2 Federal Constitution of the Swiss Confederation the elections to the National Council, which is one of two chambers of the Federal Assembly, are held according to proportional representation system. The Hagenbach-Bischoff system is used for allocating seats in National Council of the Swiss Con federation. However the above mentioned system for determining the quota of votes per each mandate creates ambiguous opinions among Swiss scientists and legal experts, which frequently comes up in discussions whether to modify it or not. In this article, the author also gives a brief description of the main political parties in Switzerland and statistics of seats allocation in 49 legislature of National Council following the elections of October 23, 2011. As a result, the author provides the full information on the process of votes counting and establishment of election results in the Swiss Confederation. The material presented in this article is particularly interesting and relevant in terms of improving the electoral legislation in the Russian Federation. The information presented by the author will be useful to all parties interested in electoral law.

    Full Text Available SWISS-PROT is a curated, non-redundant protein sequence database which provides a high level of annotation and is integrated with a large number of other biological databases. It is supplemented by TrEMBL, a computer-annotated database which contains translations of all coding sequences in the EMBL Nucleotide Sequence Database which are not yet in SWISS-PROT. Each fully curated SWISS-PROT entry contains as much up-to-date information as possible from a variety of sources and the high quality of the annotation in SWISS-PROT provides the basis for the procedure which is used to automatically annotate the TrEMBL database. The large amounts of different data types found in both databases are stored in a highly structured and uniform manner and this structured organisation means that SWISS-PROT and TrEMBL together provide a comprehensive resource with data that are readily accessible for users and easily retrievable by computer programs.

    Scientific journals currently face challenges including cost pressures caused by economic constraints, increasing rivalry among competitors, limited market potential of non-english speaking journals, increasing medical specialization with resulting market fragmentation, and internet-based competition. We therefore analyzed strategic opportunities of the journal Swiss Surgery on the basis of customer surveys and of a market analysis. Swiss surgeons expressed their interest in the continuation of the journal but also indicated their support for changes in its concept and for an increased use of electronic media. An international market analysis points-out the difficulties of national, non-english speaking journals in gaining impact points and in attracting authors and readers of scientific medical articles. Therefore, a journal such as Swiss Surgery should identify and use publication niches. The demand for a concept addressing surgical training including continuous postgraduate education was confirmed by the customers of Swiss Surgery. A corresponding offer does not presently exist in the area and could become the new focus of the journal. This change of concept may have a number of consequences: A journal focusing on surgical training and education should use the results of readers' surveys rather than impact point assignment to evaluate quality. The journal should increasingly use electronic services including data bases, pictures, videos and closed user groups to supplement the print version. At short term, however, the printed version should be continued and not be substituted by the electronic version in order to maintain the established brand "Swiss Surgery".

    Full Text Available Background: Cricket is one of the most popular game in India played by men and women of all ages. The increased physical demands on the players may be associated with an increased risk of injuries. Core muscle strength is important to prevent risk of injuries in elite cricketers. The beginners in the cricket must have enough strength of core muscles, as core is the bridge between upper and lower limbs. So, it should be strong enough to prevent low back and lower limb injuries in cricketers. The aim is to determine the effectiveness of swiss ball exercises versus floor exercises on core muscle strength in elite cricketers. The objective is to study and compare the effectiveness of swiss ball exercises and floor exercises in elite cricketers in terms of back strength. Method: The total number of students in this study were 30 eilte cricketers between 16-25 years out of which 15 subjects were included each in floor exercise(n=15 and swiss ball group(n=15. Back strength was measured before and after the intervention of 6 weeks using isokinetic analyser. Results: After the analysis, the results revealed significant improvement of back strength in both the groups(p< 0.00. The swiss ball group showed significant results when compared with floor exercise group. Conclusion: Although the study showed beneficial results in both the groups, the results reflected that swiss ball group had better improvement of core muscle strength than the floor exercise group.

    Tight glycemic control and aggressive treatment of additional cardiovascular risk factors can substantially reduce risk of diabetes-related complications. In 2013, the Swiss Society of Endocrinology and Diabetology (SSED) established national criteria on good disease management in diabetes, but little is known about compliance in clinical care. Here we assessed to what extent patients from two tertiary care centers in the German-speaking part of Switzerland enrolled in the Swiss Diabetes (SwissDiab) Registry adhere to the SSED criteria. SwissDiab is a prospective observational cohort study of patients regularly treated at Swiss tertiary diabetes centers. Data were collected through standardized annual health examinations. Baseline participant descriptive statistics, stratified by diabetes mellitus type 1 (DM1) and type 2 (DM2), were compared with SSED targets for glycemic control, blood pressure, blood lipids, weight maintenance, and ophthalmic examination. By the end of 2016, 604 participants with DM1 (40%) and DM2 (60%) had data available for analyses, 36% and 29% women, respectively. At baseline, all the SSED targets were met with two exceptions: a glycated hemoglobin A1c value DM2, respectively, received nutritional counseling in the previous year (SSED target: ≥80%). The SSED targets for good disease management in diabetes were achieved in the majority of participants at the time of enrollment, but results also highlight areas where disease management can be improved, particularly the role of nutrition counseling.

    Full Text Available The La Ramada district and the Bogota River are the principal water resources used for horticultural crop production on the Bogota Plateau, which contain channel pollutant materials, including heavy metals due to domestic and industrial activities on the Plateau. These materials have effects on crop production in this zone. The present research, under laboratory conditions, aimed to evaluate the effect of three concentrations (25, 35 and 50 µM L-1 of cadmium (Cd and chromium (Cr on imbibition, seed germination and root elongation in lettuce (Lactuca sativa var. Batavia, Swiss chard (Beta vulgaris var. cicla "White Ribbed", and spinach (Spinacia oleracea Hib. 424, three species widely cultivated on the Plateau. The three species used for evaluation showed a differential susceptibility response to Cd and Cr. In lettuce, fresh weight increase (imbibition was lower with all Cd concentrations at the last day of observation and at 25 µM L-1 of Cd in Swiss chard. Cadmium reduced seed germination by up to 46%, 97% and 8% in Swiss chard, lettuce and spinach, respectively. Also, root elongation decreased in Cd treatments by up to 57%, 89% and 56%, for Swiss chard, lettuce and spinach, respectively. Chromium, which showed fewer negative effects, decreased germination by up to 29% in Swiss chard, 6% in lettuce and 34% in spinach, as compared to the control

    We address issues related to (i) a proposal for resolving a long-standing tension between large volume cosmology and phenomenology as regards reconciliation of requirements of different gravitino masses within the same string-theoretic framework, as well as (ii) evaluation of soft supersymmetry breaking terms and open-string moduli masses in the context of type IIB large volume compactifications involving orientifolds of the Swiss-cheese Calabi-Yau WCP{sup 4}[1,1,1,6,9] with a single mobile space-time filling D3-brane and stacks of D7-branes wrapping the 'big' divisor SIGMA{sub B} as well as supporting D7-brane fluxes. In addition, we also include perturbative alpha{sup '}-corrections and non-perturbative world-sheet instanton corrections to the Kaehler potential as well as Euclidean D3-instanton superpotential. First, using the toric data for the aforementioned Swiss-cheese Calabi-Yau and GLSM techniques, we obtain in the large volume limit, the geometric Kaehler potential for the big (and small) divisor(s) in terms of derivatives of genus-two Siegel theta functions. Next, we show that as the mobile space-time filling D3-brane moves from a particular non-singular elliptic curve embedded in the Swiss-cheese Calabi-Yau to another non-singular elliptic curve, it is possible to obtain 10{sup 12} GeV gravitino during the primordial inflationary era as well as, e.g., a TeV gravitino in the present era, within the same set up for the same volume of the Calabi-Yau stabilized at around 10{sup 6}l{sub s}{sup 6}. Then by constructing local (i.e. localized around the location of the mobile D3-brane in the Calabi-Yau) appropriate involutively-odd harmonic one-form on the big divisor that lies in coker(H{sub p}artial deriv-bar,{sub -}{sup (0,1)}(CY{sub 3})->{sup i}*H{sub p}artial deriv-bar,{sub -}{sup (0,1)}(SIGMA{sub B})) and extremizing the potential, we show that it is possible to obtain an O(1)g{sub YM} from the wrapping of D7-branes on the big divisor due to

    The aim of this study is determining the amount of Al, Cu, Fe, Mn, Ni, Pb and Zn in samples of molasses and honey which were gathered from the Sakarya and Istanbul regions. In this study, trace elements in 8 honey and 20 molasses samples with different botanic features were evaluated. The sample preparation phase was performed via wet decomposition method and microwave digestion system. The accuracy of the method was checked by the standard reference material; tea leaves (INCY-TL-1) and NIST-SRM 1515-apple. The concentrations of essential trace elements (TEs) were observed in the range of 1.61 ± 0.01-287.03 ± 1.07; 0.21 ± 0.01-11.04 ± 0.12; 0.35 ± 0.03-21.71 ± 0.02 and 1.19 ± 0.01-60.90 ± 1.09 μg g(-1) for iron, copper, manganese and zinc ions, respectively, while the toxic element contents were observed in the range of 0.82 ± 0.17-3.06 ± 0.03; 0.04 ± 0.05-1.96 ± 0.03 and 0.62 ± 0.01-120.52 ± 0.10 μg g(-1) for lead, nickel and aluminum ions, respectively. The concentrations of basic TEs iron, copper, manganese and zinc were determined as 3.87 ± 0.04-16.76 ± 0.06; 0.45 ± 0.03-2.15 ± 0.01; 0.13 ± 0.01-15.02 ± 0.14 and 0.80 ± 0.09-12.03 ± 0.19 for honey samples. Also, toxic metal, lead, nickel and aluminum values in the honey samples were determined as 1.21 ± 0.12-2.46 ± 0.21; 0.28 ± 0.14-0.88 ± 0.43 and 2.11 ± 0.02-8.04 ± 0.08. A comparison between gathered data and literature values has performed and it is determined that such findings are suitable with the literature.

    Incompatibility between implant systems and the increasing complexity of esthetic restorative options frequently require dentists to obtain special training in the selection and use of prosthetic components. SwissPlus System implants have been designed to simplify restorative procedures by eliminating many ancillary restorative components. The implants are packaged on a fixture mount that also functions as a transfer and as an abutment for cemented restorations. For multiple-unit, screw-retained restorations, the prosthesis can be splinted directly to the top of the implant without an intermediate abutment. Overdenture attachments, straight, angled, screw-receiving, and custom-cast abutments complete the restorative system. This paper presents an overview of the SwissPlus System's prosthodontic aspects. Test data also illustrate intersystem compatibility and differences between SwissPlus System implants and ITI syn-Octa implants.

    to induce high level of muscle activation. PURPOSE: To compare muscle activation as measured by electromyography (EMG) of global core and thigh muscles during abdominal crunches performed on Swiss ball with elastic resistance or on an isotonic training machine when normalized for training intensity. METHODS......BACKGROUND: Swiss ball training is recommended as a low intensity modality to improve joint position, posture, balance, and neural feedback. However, proper training intensity is difficult to obtain during Swiss ball exercises whereas strengthening exercises on machines usually are performed......: 42 untrained individuals (18 men and 24 women) aged 28-67 years participated in the study. EMG activity was measured in 13 muscles during 3 repetitions with a 10 RM load during both abdominal crunches on training ball with elastic resistance and in the same movement utilizing a training machine...
