  2. Electrotherapeutic disputes: the 'Frankfurt Council' of 1891.

    2011-04-01

    Since the 1980s and 1990s, vagus nerve and deep brain stimulation, transcranial magnetic stimulation and cranial electrotherapy stimulation have found their way into neurology as therapeutic approaches to epilepsy, Morbus Parkinson and other central nervous symptoms. Moreover, these methods have proven useful and provided hope in the therapy of other diseases, most of all in psychiatry. From a historic perspective, this new emphasis on somatic therapies in the case of transcranial magnetic stimulation and cranial electrotherapy stimulation represents the return of therapeutic methods widely used in the 19th century and based on very similar techniques. Against the background of a general rise in the importance of neurobiological concepts in the neurosciences, we are now in a new situation of change. Yet, as in the 1880s and 1990s, many epistemic questions remain unresolved, the methods not yet having been standardized. In particular, the inability to explain which way and precisely how electricity induces healing processes in the body continues to put the neurosciences, which have always regarded themselves as exact and scientific in nature, in a rather uncomfortable position. There was a similar situation in the 1880s and 1990s, when positivist scientific dogmas prevailed. For ideological and professional reasons, neurologists strongly rejected the notion pioneered by Leipzig neuropsychiatrist Paul Julius Möbius that curative effects of electrotherapy were based on suggestion. One should see, however, that Möbius's actual concern was not to raise opposition towards or question electrotherapy as such, but rather to sensitize his colleagues in view of the prevailing solely materialistic-somatic approach in order that they should not neglect the psychological component of all illness, both in clinical practice and in research. A singular and very special event illustrates the heated debate among German-speaking neurologists on the psychological/suggestive effects

    1977-01-01

    We studied the thermal resistance of Staphylococcus aureus during frankfurter processing in respect to whether staphylococci are killed by the heating step of the process and whether heat injury interferes with the quantitative estimation of the survivors. With S. aureus 198E, heat injury could be demonstrated only when large numbers of cells (10(8)/g) were present and at a product temperature of 140 degrees F (60 degrees C). On tryptic soy agar and tryptic soy agar plus 7% NaCl media, at temperatures less than 140 degrees F, the counts were virtually identical; above 140 degrees F, the counts converged, with the organisms dying so rapidly that heat injury was not demonstrable. Heat injury was thus judged not to interfere with the quantitative estimation of staphylococci surviving the normal commercial heating given frankfurters. By using a combination of direct plating on tryptic soy agar and a most-probable-number technique, we detected no viable cells (less than 0.3/g) of several strains of S. aureus in frankfurters heated to 160 degrees F (71.1 degrees C). This temperature is compatible with the normal final temperature to which federally inspected processors heat their frankfurters and with the temperature needed to destroy salmonellae. PMID:563701

    Observable behaviors play the predominant role in the clinical assessment of schizophrenia, while only secondary emphasis is placed on exclusively subjective complaints. Huber employed the phenomenological approach to obtain subjective symptoms that he named "basic symptoms". Subjective symptoms constitute an important component of the schizophrenic symptomatology. They may play a predominant role during the prodromal or early phases of the disease, they may be useful in elucidating cognitive and perceptual disturbances in schizophrenia. In the last decade, the assessment of patients' subjective experiences has acquired significance with the development of several instruments for their specific evaluation. The Frankfurt Complaint Questionnaire (FCQ, Süllwold, 1986) is the instrument most widely used in Europe for assessing subjective experiences. It covers a wide range of complaints of cognitive deficits that Süllwold compiled from the complaints of schizophrenic patients. We present the French translation of the FCQ. The availability of the FCQ in French could be an important step in promoting the study of subjective experiences in research and clinical activities. PMID:9453929

    The effect of reducing pork meat concentrations from 50% to 30% and replacing it with up to 20% pork head meat on chemical composition, cooking characteristics, physicochemical and textural properties, apparent viscosity, and sensory characteristics of frankfurters was determined. The highest moisture content in frankfurters was found in the control and T1 (frankfurter with 45% pork meat + 5% pork head). Protein and fat contents in frankfurters with pork head meat added were significantly (p<0.05) higher than those in the control. When the concentration of pork head meat was increased from 0% to 20%, cooking loss, total expressible fluid separation, fat separation, and pH of frankfurters were increased, while the lightness, redness, yellowness, and apparent viscosity of frankfurters were decreased. Ash contents, cohesiveness, color, and tenderness of sensory characteristics of frankfurters added with different amounts of pork meat or pork head meat were not significantly (p>0.05) different from those of the control or there treatments. Frankfurters in T4 (frankfurter with 30% pork meat + 20% pork head) had the lowest (p<0.05) hardness and gumminess. The hardness and gumminess of frankfurters in other treatments were not significantly different (p>0.05) from that in the control. Frankfurters with higher pork head meat concentrations had lower flavor, juiciness, and overall acceptability scores. Therefore, replacing pork meat with pork head meat in the formulation could successfully produce results similar to those of control frankfurters. The best results were obtained when 10% pork head meat was used to replace pork meat. PMID:27621683

    To explore the potential as a natural auxiliary emulsifier, shaddock albedo was added into frankfurters at six different levels: 0.0, 2.5, 5.0, 7.5, 10 and 12.5 %. The emulsion capacity (EC) of meat batters and cooking properties of frankfurters were evaluated. EC of meat batters was improved with the addition of shaddock albedo and the maximum value was reached at the 5 % albedo concentration. The addition of shaddock albedo resulted in lower cooking losses of frankfurters, with the lowest value obtained at the 7.5 % level. The presence of shaddock albedo decreased the total expressible fluid (TEF) and the proportion of fat in total expressible fluid (PF) which indicated the emulsion stability of frankfurters and the lowest values both occurred at the concentration of 7.5 %. Shaddock albedo inclusion increased the lightness and yellowness of frankfurters and decreased redness. Texture profile analysis showed increased hardness and decreased chewiness of frankfurters with the addition of shaddock albedo. Consequently, shaddock albedo could be a potential source of auxiliary emulsifier filler for emulsion-type meat products. PMID:26139927

  9. Pigeon Navigation: Different Routes Lead to Frankfurt

    2014-01-01

    Background Tracks of pigeons homing to the Frankfurt loft revealed an odd phenomenon: whereas birds returning from the North approach their loft more or less directly in a broad front, pigeons returning from the South choose, from 25 km from home onward, either of two corridors, a direct one and one with a considerable detour to the West. This implies differences in the navigational process. Methodology/Principle Findings Pigeons released at sites at the beginning of the westerly corridor and in this corridor behave just like pigeons returning from farther south, deviating to the west before turning towards their loft. Birds released at sites within the straight corridors, in contrast, take more or less straight routes. The analysis of the short-term correlation dimension, a quantity reflecting the complexity of the system and with it, the number of factors involved in the navigational process, reveals that it is significantly larger in pigeons choosing the westerly corridor than in the birds flying straight - 3.03 vs. 2.85. The difference is small, however, suggesting a different interpretation of the same factors, with some birds apparently preferring particular factors over others. Conclusions The specific regional distribution of the factors which pigeons use to determine their home course seems to provide ambiguous information in the area 25 km south of the loft, resulting in the two corridors. Pigeons appear to navigate by deriving their routes directly from the locally available navigational factors which they interpret in an individual way. The fractal nature of the correlation dimensions indicates that the navigation process of pigeons is chaotic-deterministic; published tracks of migratory birds suggest that this may apply to avian navigation in general.

  11. Effect of Duck Feet Gelatin on Physicochemical, Textural, and Sensory Properties of Low-fat Frankfurters

    PubMed Central

    2014-01-01

    Duck feet gelatin (DFG) gel was added as a fat replacer to low-fat frankfurters and the effect of DFG on physicochemical, textural, and sensory characteristics of low-fat frankfurters was evaluated. DFG gel was prepared with a 20% duck feet gelatin concentration (w/w). Adding DFG decreased lightness and increased yellowness of the low-fat frankfurters (p<0.05). However, DFG did not affect redness of low-fat frankfurters (p>0.05). The statistical results indicated that adding DFG improved cooking yield of low-fat frankfurters (p<0.05). In addition, replacing pork back fat with DFG resulted in increased moisture content, protein content, and ash content of low-fat frankfurters, and the low-fat frankfurter formulated with 5% pork back fat and 15% DFG gel had the highest moisture content and lowest fat content (p<0.05). Adding of DFG increased all textural parameters including hardness, springiness, cohesiveness, chewiness, and gumminess of low-fat frankfurters (p<0.05). In terms of sensory properties, the low-fat frankfurter formulated with 5% pork back fat and 15% DFG gel showed similar satisfaction scores for the flavor, tenderness, juiciness, and overall acceptance when compared to the regular frankfurters (20% back fat). Therefore, our results suggest that DFG could be an effective novel source, as a fat replacer, for manufacturing of low-fat frankfurters. PMID:26761279

  12. Max Wertheimer, Habilitation candidate at the Frankfurt Psychological Institute.

    Max Wertheimer told Edwin B. Newman that it was pure chance that on his way to the Rhineland he prematurely got off the train in Frankfurt, and that he did so because he had an inspiration for an experiment that he wanted to perform. Most historians of psychology accept this anecdote, but fail to mention that thereby Wertheimer also mastered the next and decisive step toward his academic career in accomplishing his Habilitation. Exposing the institutional, personal, and intellectual context of Wertheimer's going to Frankfurt and giving a detailed account of the procedure of Habilitation will show that Newman's and similar reports of the episode, even if verbatim to Wertheimer's own telling, are nevertheless too improbable to accept at face value.

    1974-01-01

    Salmonella senftenberg 775W added to frankfurter emulsion was killed during normal processing in the smoke house when internal product temperature was 71.1 C (160 F) or above. The thermal destruction point of S. senftenberg 775W in frankfurters (temperature at which no viable cells were detected) was a function of the length of time of the process rather than of the starting number of cells. Heating of frankfurters to 73.9 C (165 F) substantially reduced the total non-salmonella count. For total non-salmonella bacterial flora and salmonella, relatively little thermal destruction occurred below 43.3 C (110 F). The heating step can bring about a 7-log cycle decrease (108 to 101/g) of bacteria present in the raw emulsion. The flora of this high-bacteriological-count raw emulsion was predominantly gram-negative rods. Variation in the number of bacteria (both total and salmonella) surviving at various temperatures during processing was attributed to slight variations in the temperature pattern of the smoke house during its operation. An integration process was devised which allowed calculation of exposure to temperatures above 110 F (43.3 C) on the basis of degree-minutes. Plots of degree-minutes versus log of surviving bacteria were linear. The salmonella plot had a greater slope than that of the total non-salmonella flora, indicating that salmonellae are more heat sensitive than the bacterial population as a whole. The predominant bacteria surviving the heating step were micrococci. These micrococci were able to increase in number in or on the frankfurters during storage at 5 C. PMID:4596752

    1975-01-01

    Conventional and nitrite-free frankfurters in loosely wrapped packages were compared as to their ability to support growth of Salmonella, Staphylococcus, and their naturally occurring spoilage flora at 7 C (simulating refrigerated storage) and 20 C (simulating possible temperature abuse). At 7 C Salmonella did not grow in either type of frankfurter; Staphylococcus and the natural spoilage flora sometimes grew more rapidly in the absence of nitrite, but the difference was not significant. At 20 C growth of Salmonella, Staphylococcus, and of the spoilage flora was, at most, only slightly faster on nitrite-free frankfurters. Salmonella was not suppressed in broth culture experiments at the pH and nitrite content found in frankfurters. Although either type of frankfurter can become hazardous due to growth of Salmonella or Staphylococcus, no unusual or additional hazard resulted from the omission of nitrite from frankfurters.

    Different strategies were examined for incorporation of chia flour (10%) and olive oil to improve the fat content in frankfurters. Nutritional composition, technological properties, sensory and microbiological analyses were studied as affected by the strategy used and by chilling storage. Chia increased total dietary fibre (98% insoluble dietary fibre) and minerals (K, Mg, Ca, Mn) irrespective of the incorporation strategy. Fat and energy content reduction (>26%) were achieved in all frankfurters reformulated with chia and olive oil. Chia addition increased linolenic acid and reduced processing and purge in all samples. Lightness and redness of frankfurters were affected by the presence of chia, but there was no clear evidence of influence by the mode of addition. Frankfurter texture was influenced by the strategy used to incorporate chia and olive oil and by chilling storage. Samples were judged acceptable and contained low microorganism levels. Frankfurters containing chia were suitable for labelling with certain nutrition and health claims. PMID:26745305

    2005-10-19

    The effect of the addition of increasing levels of rosemary essential oil (150, 300, and 600 mg/kg) on the generation of volatile compounds in frankfurters from Iberian and white pigs was analyzed using solid-phase microextraction coupled to gas chromatography and mass spectrometry (SPME-GC-MS). Lipid-derived volatiles such as aldehydes (hexanal, octanal, nonanal) and alcohols (pentan-1-ol, hexan-1-ol, oct-1-en-3-ol) were the most abundant compounds in the headspace (HS) of porcine frankfurters. Frankfurters from different pig breeds presented different volatile profiles due to their different oxidation susceptibilities as a likely result of their fatty acid composition and vitamin E content. Rosemary essential oil showed a different effect on the generation of volatiles depending on the type of frankfurter in which they were added. In frankfurters from Iberian pigs, the antioxidant effect of the essential oil improved with increasing levels, showing the highest activity at 600 mg/kg. In contrast, 150 mg/kg of the essential oil improved the oxidative stability of frankfurters from white pigs, whereas higher levels led to no effect or a prooxidant effect. The activity of the essential oil could have been affected by the different fatty acid compositions and vitamin E contents between types of frankfurters. SPME successfully allowed the isolation and analysis of volatile terpenes from frankfurters with added rosemary essential oil including alpha-pinene, beta-myrcene, l-limonene, (E)-caryophyllene, linalool, camphor, and 1,8-cineole, which might contribute to the aroma characteristics of frankfurters.

    2010-01-01

    In a survey of 2,312 residents living near Frankfurt Airport aircraft noise annoyance and disturbances as well as environmental (EQoL) and health-related quality of life (HQoL) were assessed and compared with data on exposure due to aircraft, road traffic, and railway noise. Results indicate higher noise annoyance than predicted from general exposure-response curves. Beside aircraft sound levels source-related attitudes were associated with reactions to aircraft noise. Furthermore, aircraft noise affected EQoL in general, although to a much smaller extent. HQoL was associated with aircraft noise annoyance, noise sensitivity and partly with aircraft noise exposure, in particular in the subgroup of multimorbid residents. The results suggest a recursive relationship between noise and health, yet this cannot be tested in cross-sectional studies. Longitudinal studies would be recommendable to get more insight in the causal paths underlying the noise-health relationship. PMID:20948931

  7. Effects of Organogel Hardness and Formulation on Acceptance of Frankfurters.

    PubMed

    Barbut, S; Wood, J; Marangoni, A G

    2016-09-01

    Different organogel formulations used as beef fat (BF) replacement (0%, 20%, 40%, 60%, and 80%) were utilized to optimize the mechanical properties of frankfurters. Organogels, made of canola oil (CO), included different concentrations of ethyl cellulose (EC) and sorbitan monostearate (SMS). They consisted of: 8% EC + 1.5% SMS referred to as organogel-I (OG-I), 8% EC + 3.0% SMS (OG-II), and 10% EC + 1.5% SMS (OG-III), which were found promising in a previous study when used at 100% replacement. Replacement of BF with organogels at all levels could bring down the very high hardness values (texture profile analysis and sensory) of frankfurters prepared using CO by itself, relative to the BF control. OG-I and OG-II quantity had no significant effect on hardness and springiness, being similar in many cases to the BF and lower than the CO control. Shear force values of all organogel treatments were not significantly different from one another, and were between the BF and CO controls. Smokehouse yield showed a pattern of decreasing losses with increasing organogel replacement level. Sensory analysis revealed that using CO by itself significantly increased hardness, but structuring the oil (via organogelation), brought it down to the BF control value in all OG-I and OG-II formulations. Juiciness was significantly reduced by using liquid oil but increased with raising the amount of organogels. Oiliness sensation increased with higher organogel substitution and was actually higher than the beef control. The study demonstrates the potential use of vegetable oil structuring in replacing the more saturated BF in emulsion-type meat products. PMID:27514694

    Microwave oven heating was evaluated for inactivation of Listeria monocytogenes on inoculated and stored frankfurters. Frankfurters formulated without/with 1.5% potassium lactate and 0.1% sodium diacetate were inoculated with L. monocytogenes (1.9 +/- 0.2 log CFU/cm(2)), vacuum-packaged, and stored (4 degrees C) to simulate conditions prior to purchase by consumers. At storage days 18, 36, and 54, packages were opened and placed at 7 degrees C, simulating aerobic storage in a household refrigerator. At 0, 3, and 7 d of aerobic storage, 2 frankfurters were placed in a bowl with water (250 mL) and treated in a household microwave oven at high (1100 W) power for 30, 45, 60, or 75 s, or medium (550 W) power for 60 or 75 s. Frankfurters and the heating water were analyzed for total microbial counts and L. monocytogenes populations. Exposure to high power for 75 s reduced pathogen levels (0.7 +/- 0.0 to 1.0 +/- 0.1 log CFU/cm(2)) to below the detection limit (<-0.4 log CFU/cm(2)) on frankfurters with lactate/diacetate, even after 54 d of vacuum-packaged storage followed by 7 d of aerobic storage. For frankfurters without lactate/diacetate, high power for 75 s caused reductions between > 1.5 and 5.9 log CFU/cm(2) from control levels of 1.5 +/- 0.1 to 7.2 +/- 0.5 log CFU/cm(2). Depending on treatment and storage time, the water used to reheat the frankfurters had viable L. monocytogenes counts of <-2.4 to 5.5 +/- 0.5 log CFU/mL. The results indicated that frankfurters should be reheated in a microwave oven at high power for 75 s to inactivate up to 3.7 log CFU/cm(2) of L. monocytogenes contamination. PMID:19799673

    Emulsion gels prepared with olive oil, chia, and cold gelling agents (transglutaminase, alginate, or gelatin) were used as fat replacers in reduced-fat frankfurter formulation. Nutritional advantages, sensory analysis, technological properties, and microbiological populations of frankfurters were evaluated along with their lipid structural characteristics over chilled storage. Frankfurters with emulsion gels showed significant improvements in fat content (lower saturated fatty acid, higher mono- and polyunsaturated fatty acid contents) and had good fat and water-binding properties. The presence of an emulsion gel reduced lightness and redness, but increased yellowness. Textural behavior of samples was significantly affected by the presence of emulsion gels and by storage. Sensory properties were not affected by the incorporation of emulsion gels, and all frankfurters were judged acceptable. Attenuated total reflectance-Fourier transform infrared spectroscopy results showed that samples with emulsion gels involve more lipid-protein interactions. Frankfurters with emulsion gels showed good stability to oxidation during storage and contained lower levels of microorganism than reduced-fat control at 85 days. PMID:25788169

    The effects of sea tangle, sea mustard, hijiki, and glasswort were investigated based on the proximate composition, salinity, cooking loss, emulsion stability, pH, color, texture profile analysis, apparent viscosity, and sensory characteristics of reduced-salt (NaCl) meat batter and frankfurters. The moisture content, salinity, lightness of the meat batter and frankfurter, hardness, gumminess, and chewiness of the reduced-salt frankfurters with sea weeds were lower than the control without seaweed (p<0.05). The protein content, springiness, and cohesiveness of the reduced-salt frankfurters were not significantly different among the treatments (p>0.05). The moisture content, salinity, cooking loss, lightness, redness, hardness, gumminess, and chewiness of treatments with sea tangle and with sea mustard were lower than the control (p<0.05). Among the sensory traits, color was highest in the control (p<0.05). The flavor was also highest in the control. The treatments with sea tangle and with sea mustard samples had high tenderness, juiciness, and overall acceptability scores similar to the control (p<0.05). The results of this study show that the combination of low-salt and seaweed in the formulation successfully improved reduced-salt frankfurters, improving sensory characteristics to levels similar to the regular salt control (1.5%).

    This study was aimed at evaluation of the effect of glasswort levels (0, 0.5, 1, and 1.5%) on the textural properties of frankfurters formulated with 0.75% NaCl. The addition of glasswort improved protein solubility (P<0.05) and apparent viscosity of frankfurters formulated with 0.75% NaCl, resulting in increased cooking yield and emulsion stability. This phenomenon might be mainly related to salts and dietary fiber within glasswort. In addition, the textural properties of frankfurter prepared with 0.75% NaCl and 1.5% glasswort showed similar properties (P>0.05) compared to those of control (1.5% NaCl). Our result suggests that the use of glasswort can be an effective approach to manufacture reduced-salt meat products. Moreover, the addition of 1.5% glasswort in frankfurters formulated with 0.75% NaCl is the optimum level without adverse effect on the texture. PMID:24769151

    This study evaluated the effects of adding glasswort hydrate containing non-meat ingredient (GM, carboxy methyl cellulose; GC, carrageenan; GI, isolated soy protein; GS, sodium caseinate) on the quality characteristics of reduced-salt, reduced-fat frankfurters. The pH and color evaluation showed significant differences, depending on the type of glasswort hydrate added (p<0.05). In the raw batters and cooked frankfurters, the addition of glasswort hydrate decreased the redness and increased the yellowness in comparison with frankfurters without glasswort hydrate. The reduction in salt and fat content significantly increased cooking loss and decreased hardness, tenderness and juiciness (p<0.05). Glasswort hydrate containing non-meat ingredient improved cooking loss, water holding capacity, emulsion stability, hardness, and viscosity of reduced-salt, reduced-fat frankfurters. The GM treatment had the highest myofibiliar protein solubility among all treatments, which was associated with emulsion stability and viscosity. The GC treatment had higher values for all texture parameters than the control. In the sensory evaluation, the addition of glasswort hydrate with non-meat ingredient improved tenderness and juiciness of reduced-salt, reduced-fat frankfurters. GM, GC, and GI treatments improved not only the physicochemical properties but also the sensory characteristics of reduced-salt, reduced-fat frankfurters. The results indicated that the use of glasswort hydrate containing non-meat ingredient was improved the quality characteristics of reduced-salt, reduced-fat frankfurters. PMID:26877638

    Shelf-life of frankfurters depends on various factors such as its composition, packaging material and method used as well as the effect of external conditions (temperature). The objective of this study was to determine the shelf-life of packaged (vacuum, shrink and modified atmosphere, MA) chicken frankfurters during storage at different temperatures. For this purpose regular and with sodium lactate addition chicken frankfurters were produced. For MA packaging (MAP), under gas mixture of 70% N(2) and 30% CO(2), a package consisting of container and heat sealable cover was used. Different laminate composition was used for vacuum and shrink packaging of frankfurters. During frankfurters storage physico-chemical (pH, a(w)), and microbiological (aerobic mesophiles, lactic acid bacteria and total bacterial count) analyses were performed. Packaging materials were analyzed for their barrier characteristic (oxygen permeability). The shelf-life of frankfurters can be extended if packaged in MA (54 days) and shrink (45 days) packaging compared to 36 days of shelf-life in vacuum packaging, at 3 (°)C. Higher shelf-life is obtained for frankfurters with lactate addition, in all packaging conditions, stored at 6 (°)C. PMID:21436233

    The Free University of Berlin and the Humboldt University of Berlin hosts the excellence cluster 264 Topoi, "The Formation and Transformation of Space and Knowledge in Ancient Civilizations". The Excellence Cluster pursues the goal of researching the interdependence of space and knowledge in the civilizations of the Ancient Near East, the Mediterranean, and Black Sea region and parts of the Eurasian steppe from the 6th millennium BC to around AD 500. Within this excellence cluster, the project A-I-11 "Lossow near Frankfurt/Oder - An Early Iron Age Cult Site of the Ancient Peripheral Zone" examines the evolution of an important cult site in Central Europe. The castle mound of Lossow was built as a fortified settlement in the late Bronze Age (10th century B.C.). After a phase of around 200 years, a supra-regionally significant, early Iron Age cult centre developed on this site (8th-6th century B.C.). Several pieces of evidence indicate that the locality had a central-site character. Typical for the site are well-shapes shafts, filled with large amounts of human and animal bones. The shafts with a diameter of about 1 meter and a depth of about 5 to 7 meters are a great challenge to near surface geophysics. Here, geophysical methods (geomagnetic gradiometry, geoelectric imaging, georadar survey) have been used to obtain a large-scale conclusive picture of the sub-surface both within the castle mount and around the perimeter. While the magnetic results reveal numerous archaeological artefacts, geoelectric imaging decipers the subsurface structure of the site.

  6. The disappearance of a "classical" ice marginal position in NE-Germany: the Frankfurt phase puzzle

    The Frankfurt phase of the Weichselian glaciation is a classical ice marginal position in the North European plain according to all geological and geomorphological maps since the end of the 19th century. Its detection is based on the connection of prominent, but rather isolated landscape features to a supposed ice margin. As in NE-Germany no till layer is connected to the proposed ice marginal position, it is usually considered to represent an active ice margin which formed during a stability phase of the downwasting from the maximum Weichselian ice extent, the Brandenburg phase, which is located about 60 km further south. This is in contrast to the supposed equivalent of the Frankfurt ice marginal position in Poland, the Poznan phase, which is documented by a more prominent landform record and an associated till. New investigations and a reinterpretation of the topography, a reevaluation of sediments in sand pits, as well as geochronological data of glaciofluvial sediments give new insights into the glacial processes as well as in the timing. The landscape was widely formed by glaciofluvial processes forming a complex pattern of intercalated outwash sediments of the advancing, as well as of the downwasting glacier of the Brandenburg phase. A detailed study of the topography by LIDAR data gives evidence of a successive ice retreat pattern south of the so called Frankfurt ice marginal area, documented in the form of a differentiated pattern of glaciofluvial sediments and till on top. An outwash plain, the Müncheberger Sandur, on which several eskers have been mapped, was classically interpreted as a proglacial feature of the Frankfurt ice marginal position. Nevertheless, a series of OSL-ages shows Weichselian ages which are not in accordance with the supposed timing as an outwash plain related to the Frankfurt ice marginal position. The ages, as well as sedimentological evidence suggest that the sandy glaciofluvial sediments belong to the proglacial sediment cycle

    Recently significant advances have been made in the collection, detection and characterization of ice nucleating particles (INPs). Ice nuclei are particles that facilitate the heterogeneous formation of ice within the atmospheric aerosol by lowering the free energy barrier to spontaneous nucleation and growth of ice from atmospheric water and/or vapor. The Frankfurt isostatic diffusion chamber (FRankfurt Ice nucleation Deposition freezinG Experiment: FRIDGE) is an INP collection and offline detection system that has become widely deployed and shows additional potential for ambient measurements. Since its initial development FRIDGE has gone through several iterations and improvements. Here we describe improvements that have been made in the collection and analysis techniques. We detail the uncertainties inherent in the measurement method and suggest a systematic method of error analysis for FRIDGE measurements. Thus what is presented herein should serve as a foundation for the dissemination of all current and future measurements using FRIDGE instrumentation.

    In the district of Frankfurt/Oder of the German Democratic Republic, faecal examinations of 143 sheep stocks revealed a 31.3 percent infection with Dicrocoelium dendriticum. In different territories of the district, the intensity of the infection with Dicrocoelium dendriticum varied remarkably. Detailed investigations demonstrated, that the parasite was limited to pastures with Brownearth soil. Routine examinations revealed the fact, that the egg-output of Dicrocoelium dendritcum was very variable during the pasture season. During the whole time of the examinations, the authors found eggs in the faeces of sheep belonging to Dicrocoelium dendriticun. In the German Democratic Republic, this helminth species is not restricted to hills with limestones. It occurs also in lowlands with small amounts of lime like the Brown-earth zones of the district Frankfurt/Oder. PMID:1190548

    This study evaluated the fate of inoculated Listeria monocytogenes on frankfurters stored under conditions simulating those that may be encountered between manufacturing and consumption. Frankfurters with or without 1.5% potassium lactate and 0.1% sodium diacetate (PL/SD) were inoculated (1.8 +/- 0.1 log CFU/cm(2)) with a 10-strain composite of L. monocytogenes, vacuum-packaged, and stored under conditions simulating predistribution storage (24 h, 4 degrees C), temperature abuse during transportation (7 h, 7 degrees C followed by 7 h, 12 degrees C), and storage before purchase (60 d, 4 degrees C; SBP). At 0, 20, 40, and 60 d of SBP, samples were exposed to conditions simulating delivery from stores to homes or food establishments (3 h, 23 degrees C), and then opened or held vacuum-packaged at 4 or 7 degrees C for 14 d (SHF). Pathogen counts remained relatively constant on frankfurters with PL/SD regardless of product age and storage conditions; however, they increased on product without antimicrobials. In vacuum-packaged samples, during SHF at 4 degrees C, the pathogen grew faster (P < 0.05) on older product (20 d of SBP) compared to product that was fresh (0 d of SBP); a similar trend was observed in opened packages. At 7 degrees C, the fastest growth (0.35 +/- 0.02 log CFU/cm(2)/d) was observed on fresh product in opened packages; in vacuum-packages, growth rates on fresh and aged products were similar. By day 40 of SBP the pathogen reached high numbers and increased slowly or remained unchanged during SHF. This information may be valuable in L. monocytogenes risk assessments and in development of guidelines for storage of frankfurters between package opening and product consumption. PMID:19021814

    This report presents the results of computations performed with the COMPARE/MOD1 and BEACON/MOD3 computer codes for selected Battelle-Frankfurt loss-of-coolant accident experiments. COMPARE is used widely to perform nuclear power plant containment subcompartment analyses, and BEACON is an advanced multiphase, multidimensional best-estimate code. The objective of this study was to evaluate the margins of COMPARE calculations by comparing them with BEACON calculations and test data. The calculations were performed for the Battelle-Frankfurt D3, D6, and C9 tests. Descriptions of the two codes and the Battelle-Frankfurt experiments are included. Comparisons of the codes' calculations and experimental data for absolute pressure, differential pressure, and temperature are presented for margin evaluation. Evaluations of the sensitivity of BEACON calculations to variations in model noding, form loss, and vent area modeling are prsesented. Conclusions summarizing the results of the COMPARE margin evaluation and BEACON sensitivity studies are given as well.

    2009-06-01

    The antimicrobial lauric arginate (LAE) alone or in combination with an antimicrobial liquid smoke extract was studied as a postlethality treatment against Listeria monocytogenes on vacuum-packaged frankfurters. Treatment with 2 ml of 5,000 ppm of LAE reduced L. monocytogenes from 7.13 to 5.82 log CFU per package on day 0, and treatment with 3 ml reduced populations from 7.22 to 5.79 log CFU per package on day 0. Treatment with LAE and smoke flavor did not result in significantly different populations of L. monocytogenes (P < 0.05) compared with LAE alone. Log reductions on frankfurters 48 h after treatment with 3 to 4.5 ml of 5000 ppm of LAE ranged from 1.80 to 2.22, but these values were not significantly different between treatment volumes. Populations on dip-inoculated frankfurters 1 h after spraying with 2.5 ml of water (control) were 7.69 log CFU per package, and frankfurters treated with 2.5 ml of 5000 or 8000 ppm of LAE had populations of 6.03 and 5.85 log CFU per package, respectively. On spot-inoculated frankfurters, spray treatment with 2.5 ml of water resulted in L. monocytogenes counts of 8.16 log CFU per package after 1 h, whereas spray treatment with LAE at 5000 and 8000 ppm reduced counts within 1 h to 6.80 and 6.13 log CFU per package, respectively. All treatments resulted in reductions of > or = 1.68 log CFU per package, and many of the treatments caused a > 2-log reduction within 48 h. In this study, the shortterm efficacy of LAE against L. monocytogenes on vacuum-packaged frankfurters was demonstrated, providing support for use of this postlethality treatment on frankfurters and sausages for control of this pathogen.

    The aim of this work was to evaluate the quality and sensory characteristics of RTE frankfurter-type sausage cured with celery juice powder and including red wine. Four frankfurter treatments including a conventionally cured treatment without red wine (control) and three treatments cured with pre-converted vegetable juice powder and 0%, 5% or 10% (v/w) red wine were prepared. Results showed that adding 5% red wine increased the a*-value, and the textural resilience, cohesiveness and springiness of the frankfurters, as well as decreased lipid/protein oxidation of the final products. Added wine also introduced new volatiles (alcohol and ester compounds) to the frankfurters. The principal component (PC) analysis showed that the pre-converted vegetable juice powder achieved the same effects as the conventional curing agents for typical frankfurter properties. However, the addition of excess amounts of red wine (10%) to the meat batter decreased the pH of meat batter and accelerated lipid oxidation. PMID:27388819

    Stepwise regression, Genetic Algorithm-Artificial Neural Network (GA-ANN) and Co-Active Neuro Fuzzy Inference System (CANFIS) were used to predict the effect of Satureja extracts (water and ethanol) on the population dynamics of Pseudomonas aeruginosa in a complex food system (Frankfurter sausage). The stepwise regression, GA-ANN and CANFIS were fed with four inputs: concentration (at five levels 0, 2000, 4000, 6000 and 8000 ppm), type of extract (water and ethanol), temperature (at three levels 5, 15 and 25°С) and time (1-20 days). The results showed that the stepwise regression was good for modeling the population dynamics of P. aeruginosa (R(2) = 0.92). It was found that ANN with one hidden layer comprising 14 neurons gave the best fitting with the experimental data, so that made it possible to predict with a high determination coefficient (R(2) = 0.98). Also, an excellent agreement between CANFIS predictions and experimental data was observed (R(2) = 0.96). In this research, GA-ANN was the best approach to simulate the population dynamics of P. aeruginosa. Furthermore, Satureja bachtiarica ethanol extract was able to reduce P. aeruginosa population, showing stronger effect at 5 °C and the concentration of 8000 ppm. PMID:26079732

    The objective of this study was to evaluate anti-listerial efficacy of salts of organic acids, and their impact on the quality of frankfurters. Beef frankfurters were manufactured by incorporating organic acids in 5 different combinations: (1) control (no marinade addition; C); (2) sodium lactate (2% wt/wt; SL); (3) potassium lactate (2% wt/wt; PL); (4) sodium citrate (0.75% wt/wt; SC); and (5) sodium lactate (2% wt/wt)/sodium diacetate (0.25% wt/wt; SL/SD). Cooked frankfurters were inoculated with streptomycin-resistant (1500 μg/mL) L. monocytogenes (7 log₁₀ CFU/frank). Inoculated and noninoculated frankfurters were vacuum packaged and stored at 4 °C. Samples were taken weekly up to 10 wk for estimation of L. monocytogenes as well as aerobic plate count (APC) and psychrotrophs (PSY), respectively. Total of 2 independent trials of the entire experiment were conducted. Noninoculated beef frankfurters were evaluated weekly by untrained sensory panelists for 7 wk. SL, PL, and SC treatments did not (P > 0.05) adversely affect consumer acceptability through 8 wk although, SL/SD treatment was significantly (P ≤ 0.05) less preferred across all sensory attributes. SL/SD treatment negatively affected product quality, but was able to control APC, PSY, and L. monocytogenes levels. SC performed similar to the control throughout the 8, 9, and 10 wk storage periods, providing no benefit for inhibiting L. monocytogenes (increasing from 7 logs CFU/frank to 10 logs CFU/frank throughout storage) or extending shelf life of the beef frankfurters. In conclusion, 2% SL and PL, and 2% SL/0.25% SD may be effective L. monocytogenes inhibitors (maintaining inoculation levels of 7 logs CFU/frank during storage), but changes in SL/SD treatment formulation should be studied to improve product quality.

  15. Between Marxism and psychoanalysis: antifascism and antihomosexuality in the Frankfurt School.

    PubMed

    1995-01-01

    In their efforts to utilize individualist psychoanalysis as a tool for understanding mass behavior, the social theorists associated with the Frankfurt School increasingly came to rely on a static, essentializing construction of sexuality which ultimately led to an equation of fascism and homosexuality. Heretofore unexamined in studies of the Frankfurt School, this equation will here serve as the starting point for a fundamental critique of the concept of sexuality developed by this influential circle of Marxist thinkers. While directed at the concept of sexuality, such a critique more importantly opens up the underlying understanding of the social and psychological realms advanced by Critical Theory. Attending to the equation of homosexuality and fascism as the central point of concern, this essay will first trace the introduction of psychoanalysis into Critical Theory through Erich Fromm and then investigate the extent of Fromm's influence on the concept of sexuality propounded by his colleagues, especially Max Horkheimer and Theodor W. Adorno. Finally, it will take up a frequently overlooked essay by Herbert Marcuse which promoted a vision of sexuality radically different from that of his associates. PMID:8655974

    In this study, we investigated the effects of reducing fat levels from 30% to 25, 20, and 15% by substituting pork fat with water and pumpkin fiber (2%) on the quality of frankfurters compared with control. Decreasing the fat concentration from 30% to 15% significantly increased moisture content, redness of meat batter and frankfurter, cooking loss, and water exudation, and decreased fat content, energy value, pH, and lightness of meat batter and frankfurter, hardness, cohesiveness, gumminess, chewiness, and apparent viscosity. The addition of 2% pumpkin fiber was significantly increased moisture content, yellowness of meat batter and frankfurter, hardness, cohesiveness, gumminess, chewiness, and apparent viscosity, whereas reduced cooking loss and emulsion stability. The treatment of reduced-fat frankfurters formulated with 20 and 25% fat levels and with pumpkin fiber had sensory properties similar to the high-fat control frankfurters. The results demonstrate that when the reduced-fat frankfurter with 2% added pumpkin fiber and water replaces fat levels can be readily made with high quality and acceptable sensory properties.

    Recently significant advances have been made in the collection, detection, and characterization of ice nucleating particles (INP). Ice nuclei are particles that facilitate the heterogeneous formation of ice within the atmospheric aerosol by lowering the free energy barrier to spontaneous nucleation and growth of ice from atmospheric water and/or vapor. The Frankfurt isostatic diffusion chamber (FRIDGE) is an INP collection and offline detection system that has become widely deployed and shows additional potential for ambient measurements. Since its initial development FRIDGE has gone through several iterations and improvements. Here we describe improvements that have been made in the collection and analysis techniques. We detail the uncertainties inherent in the measurement method, and suggest a systematic method of error analysis for FRIDGE measurements. Thus what is presented herein should serve as a foundation for the dissemination of all current and future measurements using FRIDGE instrumentation.

    The one-day meeting on Synthetic DNA (January 24, 2012) organized by and held at the DECHEMA in Frankfurt attracted about 100 participants from academia and industry interested in synthesizing DNA and its applications in synthetic biology. In recent years the cost for synthetic DNA reduced from 7€/bp to 0.35€/bp which has opened up many new possibilities for molecular biology. You can purchase the gene, cDNA, oligo library or full vector specifically for a particular expression host and apply synthetic biology principles to produce or create new drugs, vaccines or any other biotechnological products. There are, however, great concerns within society to produce organisms that do not exist in nature, and the potential misuse of them. Adressing these concerns and to use a clear terminology that do not cause misunderstandings are important issues within the field, which were also discussed at this meeting. PMID:22461398

    2014-02-01

    The effects of reducing pork fat levels from 30% to 20%, 15%, and 10% by partially substituting pork back fat with a makgeolli lees fiber were investigated regarding approximate composition, energy value, pH, color, cooking loss, emulsion stability, texture profile analysis, apparent viscosity, and sensory evaluation. The moisture and ash contents, redness, and yellowness were higher in reduced-fat frankfurters containing makgeolli lees fiber than in the control with 30% fat. With increasing fat levels, samples displayed higher pH, lightness, hardness, cohesiveness, gumminess, chewiness, apparent viscosity, and sensory quality, while displaying lower cooking loss and total expressible fluid. The results show that fat levels of frankfurters with added makgeolli lees fiber can be successfully reduced. Thus, 20% fat frankfurters with the addition of 2% makgeolli lees fiber are similar in quality to regular frankfurters with 30% fat. PMID:24200582

    The operational limits of the Tower Shielding Reactor-2 (TSR-2) have been revised to account for placing the reactor in a beam shield, which reduces convection cooling during a loss-of-coolant accident (LOCA). A detailed heat transfer analysis was performed to set operating time limits which preclude fuel damage during a LOCA. Since a LOCA is survivable, the pressure boundary need not be safety related, minimizing seismic and inspection requirements. Measurements of reactor component emittance for this analysis revealed that aluminum oxidized in water may have emittance much higher than accepted values, allowing higher operating limits than were originally expected. These limits could be increased further with analytical or hardware improvements. 5 refs., 7 figs.

    Commercially prepared frankfurters were formulated with and without approximately 1.4% potassium lactate and 0.1% sodium diacetate and were subsequently processed in cellulose casings coated with and without nisin (approximately 50,000 IU per square inch of internal surface area) to control the outgrowth of Listeria monocytogenes during refrigerated storage. The frankfurters were inoculated with approximately 5 log CFU per package of a five-strain mixture of L. monocytogenes and then vacuum sealed before being stored at 4 degrees C for 60 to 90 days. Surviving organisms were recovered and enumerated by rinsing each package with 18 ml of sterile 0.1% peptone water and plating onto MOX selective agar. The data for each of two trials were averaged. In packages that contained frankfurters formulated with potassium lactate and sodium diacetate and prepared in nisin-coated casings, L. monocytogenes levels decreased by 1.15 log CFU per package after 90 days of storage. L. monocytogenes levels decreased by 0.95 log CFU per package in frankfurters that were prepared in casings that were not coated with nisin. In packages of frankfurters that were formulated without potassium lactate and sodium diacetate and prepared in nisin-coated casings, L. monocytogenes levels decreased by 0.88 log CFU per package after 15 days of storage but then increased appreciably thereafter over a 60-day period of refrigerated storage. There was also an appreciable increase in pathogen numbers during 60 days of storage in otherwise similar frankfurters formulated without potassium lactate and sodium diacetate prepared in casings that were not coated with nisin. These data confirm that potassium lactate and sodium diacetate display listeriostatic activity as an ingredient of commercial frankfurters. These data also establish that cellulose casings coated with nisin display only moderate antilisterial activity in vacuum-sealed packages of commercially prepared frankfurters during storage at 4

    The aim of this paper was to design and analyse the nutritional composition (fatty acid profile, cholesterol, mineral and amino acid content) of low-fat frankfurters enriched with n-3 polyunsaturated fatty acids (PUFA) (using algal oil to add 400mg of docosahexanoic acid - DHA/100g of product) as affected by the addition of seaweed (5.5% Himanthalia elongata) and the partial substitution (50%) of animal fat by olive oil (as a source of monounsaturated fatty acids - MUFA) or combinations of olive oil and seaweed. Reduction of NaCl level was also studied. The presence of algal oil produced frankfurters with high long-chain n-3 PUFA contents. The partial substitution of the pork fat by olive oil reduced (P<0.05) saturated fatty acids (SFA) and promoted (P<0.05) MUFA. A healthier lipid formulation (algal and olive oils and the reducing animal fat) produced a good balance of MUFA/SFA, PUFA/SFA and n-6/n-3 ratios. Although adding seaweed had little effect on the lipid and amino acid profiles of frankfurters, it does constitute a means to produce low-sodium products with important dietary fibre content, with better Na/K ratios and rich in Ca.

    This study investigates the effect of bovine heart surimi-like material (BHSM) used as a back fat replacer, on the physicochemical and sensory characteristics of frankfurter-type sausages. Frankfurter-type sausage with added BHSM had a higher moisture content and lower fat content than the control. In addition, the samples with added BHSM had higher pH, cooking loss and 2-thiobarbituric acid-reactive substance (TBARS) value and lower water exudation than the control. The sausage formulation with 40% BHSM was more effective in delaying lipid oxidation without affecting cooking loss compared to the 60% BHSM treatment sample. Results showed that hardness values increased upon replacement with BHSM, and sausages manufactured with 40% BHSM had higher lightness and lower redness values. Panelists found there were no differences in color, odor, and tenderness scores and the overall acceptability score found that treatment samples containing 20% and 40% BHSM were preferable to the control after storage for 14 d. These results indicate that fat replacement with BHSM was beneficial to the quality of frankfurter-type sausages, and acceptable reduced-fat products can be produced when back fat is replaced with up to 40% BHSM.

    Background: There is a paucity of data on the outcome following the treatment for acute lymphoblastic leukemia (ALL) from developing countries. Materials and Methods: Two hundred and thirty-eight consecutive patients with ALL <30 years of age diagnosed between January 2005 and December 2011 were analyzed retrospectively. Patients were treated modified Berlin, Frankfurt, and Munster 95 protocol. Event-free survival (EFS) was calculated using Kaplan–Meier survival analysis and variables were compared using log-rank test. Results: The EFS was 63.4% at a median follow-up was 32.7 months. On univariate analysis National Cancer Institute (NCI) risk stratification, sex, white blood cell count, day 8 blast clearance, and income were significantly associated with EFS. However, on multivariate analysis only female sex (P = 0.01) and day 8 blast clearance (P = 0.006) were significantly associated with EFS. Seventy-four of 238 (31%) patients had recurrent leukemia. The common sites of relapse were bone marrow in 55/74 (75%) patients and central nervous system in 11/74 (20%) patients. Conclusion: Compared to western data, there was an increased proportion of NCI high-risk patients and T-cell immunophenotype in our study. There has been an improvement in outcome of patients with ALL at our center over the last 2 decades. Female sex and clearance of blast in peripheral blood by day 8 of induction was associated with better EFS. PMID:26811597

    In order to develop a healthy low-fat frankfurter-type sausage, different formulations were developed with tilapia viscera surimi (T1) and two with mechanically separated tilapia meat (MSTM) surimi (T2 and T3), all without pig lard addition. Due to technological problems observed for T1 sausage during cooking, it was not further investigated. The functionality of the other two formulations was evaluated based on proximate composition, pH, water activity, and texture. Finally, microbiological and sensory analyses based on acceptance tests were performed. Listeria monocytogenes and Salmonella spp. were found to be absent. T2 showed higher frequencies for the attributes color (90.0%) and overall acceptability (86.7%), while T3 showed higher frequencies for taste (86.7%) and texture (96.7%). The surimi concentration was reflected in the physical properties of the sausages. It was found that the addition of MSTM surimi to sausage favored greater cutting strength (3.9 N for T2 and 4.9 N for T3). Beyond the surimi utilization, the total replacement of pig lard by cassava starch and soybean protein had also contributed with the texture properties. PMID:24804055

During the one year between these meetings, antibody drug conjugates (ADCs) have confirmed their technological maturity and their clinical efficacy in oncology. Brentuximab vedotin (ADCETRIS (TM) ) gained approval by the US Food and Drug Administration in August 2011 and trastuzumab emtansine (T-DM1) confirmed impressive clinical efficacy responses in a large cohort of breast cancer patients. During the 4th WADC meeting, antibody-maytansinoid conjugates were showcased by representatives of ImmunoGen (T-DM1, SAR3419, lorvotuzumab mertansine/IMGN801, IMGN529 and IMG853) and Biotest (BT-062). Data on antibody-auristatin conjugates were presented by scientists and clinicians from Seattle Genetics and Takeda (brentuximab vedotin), Pfizer (5T4-MMAF), Agensys/Astella (AGS-16M8F), Progenics (PSMA-ADC) and Genmab (anti-TF ADCs). Alternative payloads such as calicheamicins and duocarmycin used for preparation of ADCs were discussed by Pfizer and Synthon representatives, respectively. In addition, emerging technologies, including site-directed conjugation (Ambrx), a protein toxin as payload (Viventia), hapten-binding bispecific antibodies (Roche), and use of light activated drugs (Photobiotics), were also presented. Last but not least, progresses in solving Chemistry Manufacturing and Control, and pharmacokinetic issues were addressed by scientists from Genentech, Pfizer, Novartis and Pierre Fabre.

    In order to be able to understand how body supply was maintained at the Dr. Senckenbergische Anatomie from 1933 to 1945 - with special emphasis on victims of the National Socialist regime - we have collected information from various and often fragmentary sources. The documents reveal that during this period at least 474 bodies were brought to the anatomical institute. Among them were the bodies of at least 71 prisoners, 51 of whom had been executed, and the bodies of 8 inmates of (labor-) camps. 356 unclaimed bodies were received, some of them may stem from victims of "euthanasia" programs. The sources of 39, as of yet, unnamed bodies could not be verified. The current collections and the catalogs were screened for remains of victims of the National Socialist regime, but none were found. The vast majority of the bodies were used for teaching purposes. Hans Schreiber, one of the directors of the institute, whose biography is provided here, used at least 9 additional executed individuals for his research. Wherever possible, we have identified the victims of the National Socialist regime, executed persons and the inmates of (labor-) camps, whose bodies were used by the anatomists in Frankfurt, by name. Among the victims was Georg Fröba, a communist philanthropist, whose biography is provided. PMID:26198687

    Recommendations for prevention of infection in dentistry have been published in many countries and in Germany as well. In a pilot project in collaboration with the Public Health Service of the City of Frankfurt and the chamber of dentists in Hesse, compliance with these recommendations was studied in dental practices in Frankfurt/M in 2005. After being informed about the recommendations, more than 50% of the 560 Frankfurt dentists agreed to participate in this project, and 127 of these practitioners were visited by experts of the dentist chamber. Hygienic standards in the practices were examined using a checklist. A proper hygiene schedule was observed in 84% of the practices. Facilities for hand hygiene such as dispensers for soap, disinfectant and towels were available in 98, 93 and 92% of the practices, and personal protective equipment such as gloves, masks, eye wear and gowns was found in 98, 100, 98 and 88% of the practices, respectively. Reprocessing of dental instruments was done either manually (52%), manually in combination with ultrasonic cleaning (48%) or by using special reprocessing machines (32%). Steam sterilization was used in all practices; in some practices gravity displacement sterilizers were used (14%), whereas in most of the practices (61%) a high-speed prevacuum sterilizer was available -- especially in dental surgeon practices (77%). Monitoring and documentation of the sterilization process was done automatically (33%) or by hand (55%). In 80% of the practices, pressure, temperature, time and person responsible were documented. Documents of routine maintenance and regular biological testing of the sterilizers could be shown in 93 and 84% of the practices. The Frankfurt pilot project based on information and advice in combination with control has proven to be successful in the majority of practices enrolled. Encouraged by this experience, the chamber of dentists wants to implement this project all over the state of Hesse. The intention is to

    A prospective calculation of disease-related social and economic costs due to night-time aircraft noise in the vicinity of Frankfurt/Main airport was performed for the calendar years 2012-2021. It was based on risk estimates for a variety of diagnostic entities (cardiovascular disease, depression, psychosis, diabetes mellitus, dementia and Alzheimer's disease, all cancers except malignancies of the respiratory system) from a previous case-control study on more than 1 million persons enrolled in compulsory sickness funds in the vicinity of the Cologne-Bonn airport, on disease-related cost estimates performed by the German Federal Statistical Office for the calender years 2002-2008, and calculations of the population exposed to night-time aircraft noise in the vicinity of Frankfurt/Main airport (2005 aircraft routes and flight frequencies). Total estimated costs came to more than 1.5 billion € with an excess of 23 400 cases of diseases treated in hospitals and of 3 400 subsequent deaths. PMID:23456959

    Lipid oxidation, colour stability and physico-chemical quality of pork frankfurters with the incorporation of 0.30% sea buckthorn (SBT), 0.10% grape seed (GSE), 0.03% green tea (GTE), 0.12% fenugreek seed (FSE) and 0.10% Acacia catechu (ACE) were studied during 20 days of refrigerated aerobic storage. The SBT and ACE were identified as being the most effective antioxidants to retard lipid oxidation with the potency decreasing in the following order: SBT>ACE>GSE>GTE>FSE based on thiobarbituric acid reacting substances, peroxide value and free fatty acids. In all samples pH and aw decreased during storage period. The L* value of treated as well as control samples decreased over time while SBT and ACE exhibited an increased redness producing higher a* values than other treatments. However, GTE was more effective in increasing b* values than other treatments at the end of storage. The results suggest that functional plant-derived extracts can be valuable to the modification of frankfurter formulations for improved oxidative stability as well as quality characteristics.

    This study evaluated the effects of frankfurter fat content on Listeria monocytogenes resistance to heat stress and gastric fluid, and the Caco-2 cell invasion efficiency of the pathogen. A 10-strain mixture of L. monocytogenes was inoculated on frankfurters formulated with 10%, 20%, and 30% fat content (10%: F10, 20%: F20, 30%: F30) and stored at 10℃ for 30 d. The samples were analyzed for L. monocytogenes resistance to heat stress and a simulated gastric fluid challenge. The total bacteria and L. monocytogenes survival rates were measured on tryptic soy agar plus 0.6% yeast extract and Palcam agar, respectively. L. monocytogenes colonies inoculated on F10, F20, and F30 samples were used for a Caco-2 cell invasion assay. In general, no obvious differences were observed between the survival rates of total bacteria and L. monocytogenes grown on different fat contents under heat stress and gastric fluid challenge. However, L. monocytogenes obtained from the F30 samples had a significantly higher Caco-2 cell invasion efficiency than those in the F10 and F20 samples (p<0.05). These results indicate that although high fat content in food may not be related to L. monocytogenes resistance to heat stress and gastric fluid, it may increase the Caco-2 cell invasion efficiency of the pathogen.

    The present investigation focuses on the textural properties, sensory attributes and color changes of beef frankfurter, beef ham and meat-free sausage produced by different levels of bleached tomato pomace. The texture and color profile were performed using an instrumental texture analyzer and colorimeter. The findings indicated that tomato pomace-added sausages had higher water holding capacity (WHC) compared to that of commercial samples. The frankfurters containing 5 and 7% (w/w) tomato pomace had the highest redness (a*), chroma (C*) and color differences (ΔE) values, while the meat-free sausages containing 7% (w/w) tomato pomace had significant (p<0.05) values for lightness (L*) and yellowness (b*). Furthermore, there were no significant (p>0.05) color differences between beef ham samples (with and without tomato pomace). A significant progression in the textural hardness and chewiness of systems containing tomato pomace was observed as well as higher sensory scores by panelists. According to sensorial evaluations, bleached tomato pomace improved the consumer acceptability and preference. PMID:24769097

    This article reports a study of the physicochemical, sensory and microbiological characteristics of low-fat (10%) and n-3 PUFA-enriched frankfurters as affected by addition of seaweed (5% Himanthalia elongata), partial substitution (50%) of animal fat by olive oil and chilled storage (41days at 2°C). The presence of seaweed improved water and fat binding properties, reduced (P<0.05) lightness and redness and increased (P<0.05) the hardness and chewiness of low-fat frankfurters enriched with n-3 PUFA. The effect of olive oil on those characteristics was less pronounced than that of seaweed. Replacing pork backfat with olive oil in frankfurters produced acceptable sensory characteristics, similar to control, while addition of seaweed resulted in less acceptable products, due mainly to the special flavour of the seaweed. Formulation and storage time affected the total viable count and lactic acid bacteria count. Frankfurters containing olive oil and seaweed had the highest total viable count from day 14 of storage, with lactic acid bacteria becoming the predominant microflora. PMID:20416775

    This article examines the suitability of filled hydrogel particles for use as a delivery system for n-3 long chain PUFAs in low-fat frankfurters. Their effects on product characteristics over chilled storage were compared with those of frankfurters containing all-pork fat (control) or a comparable amount of fish oil (n-3 LCPUFA) incorporated in liquid form or in an oil-in-water emulsion. In modified samples n-3 fatty acids ranged between 801.34 to 996.37 mg/100g as opposed to 66 mg/100g in all-pork fat product. As compared with the control, hardness and chewiness values were similar (P>0.05) in filled hydrogel frankfurter. The presence of fish oil favoured lipid oxidation to varying degrees depending on delivery system, in descending order: direct oil addition>oil-in-water emulsion>hydrogels. Sensory evaluation demonstrated the advantages, from a sensory point of view, of hydrogel filled particles as n-3 delivery systems in frankfurters. PMID:26232749

    Mechanically separated chicken meat has become a common ingredient of comminuted sausage products, as 'frankfurters', mainly due to its low price. The present work aimed to develop a frankfurter from mechanically separated chicken meat surimi-like material, and evaluated the chemical, rheological, microbiological and sensorial properties of this product. The response surface methodology was utilized to investigate the effects of the soybean protein, potato starch and pig lard on the texture of the obtained frankfurters. For this purpose, five levels of each factor were evaluated: soybean protein varied from 0% to 6%, potato starch from 0% to 10% and pig lard from 2% to 12%. The regression analysis of the model showed that the soybean protein exerted a linear positive effect and a quadratic negative effect in the compression force of the product (p < 0.05), and that the variable which more influenced the shear force was the potato starch, presenting linear and quadratic effects (p < 0.05). The highest composite design averages obtained were 202.2 g for breaking force, 7.9 cm for deformation, 10.1 N for shear force, and 90.9 N.s for work of shearing. The obtained models presented high determination coefficients, explaining 97.31%, 97.83%, 97.49%, and 95.39% of the breaking force, deformation, shear force and work of shearing variabilities, respectively. The microbiological analysis demonstrated that the achieved results were below the limits fixed by the FDA. The mechanically separated chicken meat surimi-like material frankfurter presented 72.2% of acceptability and 59.3% of the examiners found the color of the product slightly lighter than the ideal. Finally, the frankfurter-type sausages, without pork fat, produced and characterized here have presented promising characteristics for commercial applications. PMID:23729422

    Natural and organic food regulations preclude the use of sodium nitrite/nitrate and other antimicrobials for processed meat products. Consequently, processors have begun to use natural nitrate/nitrite sources, such as celery juice/powder, sea salt, and turbinado sugar, to manufacture natural and organic products with cured meat characteristics but without sodium nitrite. The objective of this study was to compare physio-chemical characteristics that affect Clostridium perfringens and Listeria monocytogenes growth in naturally cured and traditionally cured commercial frankfurters, hams, and bacon. Correlations of specific product characteristics to pathogen growth varied between products and pathogens, though water activity, salt concentration, and product composition (moisture, protein and fat) were common intrinsic factors correlated to pathogen growth across products. Other frequently correlated traits were related to curing reactions such as % cured pigment. Residual nitrite and nitrate were significantly correlated to C. perfringens growth but only for the ham products. PMID:22857852

    The objective of this study was to investigate natural antimicrobials including cranberry powder, dried vinegar and lemon juice/vinegar concentrate, and post-lethality interventions (lauric arginate, octanoic acid, thermal treatment and high hydrostatic pressure) for the control of Listeria monocytogenes on alternatively-cured frankfurters. Lauric arginate, octanoic acid, and high hydrostatic pressure (400 MPa) reduced L. monocytogenes populations by 2.28, 2.03, and 1.88 log 10 CFU per g compared to the control. L. monocytogenes grew in all post-lethality intervention treatments, except after a 600 MPa high hydrostatic pressure treatment for 4 min. Cranberry powder did not inhibit the growth of L. monocytogenes, while a dried vinegar and a vinegar/lemon juice concentrate did. This study demonstrated the bactericidal properties of high hydrostatic pressure, octanoic acid and lauric arginate, and the bacteriostatic potential of natural antimicrobial ingredients such as dried vinegar and vinegar/lemon juice concentrate against L. monocytogenes.

    Different early intervention programs, developed predominantly in the US, for preschool aged children with autism spectrum disorders (ASD) have been published. Several systematic review articles including a German Health Technology Assessment on behavioural and skill-based early interventions in children with ASD reported insufficient evidence and a substantial problem of generalisability to the German context. In Germany, approx. 2-5 h early intervention is supported by social services. Here, we report the results of a 1 year pre-post pilot study on a developmentally based social pragmatic approach, the Frankfurt Early Intervention program FFIP. In FFIP, individual 2:1, behaviourally and developmentally based therapy with the child is combined with parent training and training of kindergarten teachers. Treatment frequency is 2 h/week. Outcome measures were the Vineland Adaptive Behaviour Scales II (VABS), mental age and the ADOS severity score. Improvements after 1 year were observed for the VABS socialisation scale and the mental age quotient/IQ (medium effect sizes). Results are comparable with several other studies with a similar or slightly higher therapeutic intensity implementing comparable or different early intervention methods or programs. Compared to most high-intensity programs (30-40 h/week), lower cognitive gains were observed. Results have to be replicated and assessed by a randomized-controlled study before any final conclusions can be drawn. PMID:22460295

    The effect of two important nonmeat constituents (starch and sodium caseinate) and fat content on the sensory perception of frankfurter sausages has been assessed for two mixture amounts (17% and 27%). A strong correlation among objective fattiness, elasticity, and chewiness has been established; these correlate negatively to consistency and hardness. This has been attributed to the protein gel disruption arising from local phase separations. Hedonic consistency, elasticity, and chewiness showed a very strong positive correlation to one another. Contour plots, based on responses of principal component axes, show that lard is important in increasing the objective sensory intensities of fattiness, chewiness, and elasticity, and for decreasing hardness and consistency. In higher lard proportions, caseinate and starch decrease the red color intensity and the acceptability of chewiness, elasticity, and consistency. Optimization of the component amounts was performed using response trace plots. After redundancy analysis, sensory and instrumental variables were found in very good mutual agreement; hardness was assessed as the most important mechanical variable, followed by chewiness.

    Until the beginning 1930's the traditional dogma that the human central nervous system (CNS) did not possess any abilities to adapt functionally to degenerative processes and external injuries loomed large in the field of the brain sciences (Hirnforschung). Cutting-edge neuroanatomists, such as the luminary Wilhelm Waldeyer (1836-1921) in Germany or the Nobel Prize laureate Santiago Ramón y Cajal (1852-1934) in Spain, debated any regenerative and thus "plastic" properties in the human brain. A renewed interest arose in the scientific community to investigate the pathologies and the healing processes in the human CNS after the return of the high number of brain injured war veterans from the fronts during and after the First World War (1914-1918). A leading research center in this area was the "Institute for the Scientific Study of the Effects of Brain Injuries," which the neurologist Ludwig Edinger (1855-1918) had founded shortly before the war. This article specifically deals with the physiological research on nerve fiber plasticity by Albrecht Bethe (1872-1954) at the respective institute of the University of Frankfurt am Main. Bethe conducted here his paradigmatic experimental studies on the pathophysiological and clinical phenomena of peripheral and CNS regeneration. PMID:26941616

    The effectiveness of pulsed UV-light on the microbial load and quality of unpackaged and vacuum-packaged chicken frankfurters was investigated. Samples were inoculated with Listeria monocytogenes Scott A on the top surfaces, and then treated with pulsed UV-light for 5, 15, 30, 45, and 60 s at 5, 8, and 13 cm distance from the quartz window in a pulsed UV-light chamber. Log reductions (CFU/cm(2)) on unpackaged samples were between 0.3 and 1.9 after 5-s treatment at 13 cm and 60-s treatment at 5 cm, respectively. Log reductions on packaged samples ranged from 0.1 to 1.9 after 5-s treatment at 13 cm and 60-s treatment at 5 cm, respectively. The temperature changes of samples and total energy (J/cm(2)) received at each treatment condition were monitored. The extent of lipid peroxidation and the color were determined by thiobarbituric acid-reactive substances (TBARS) test and CIELAB color method, respectively. Lipid peroxidation of samples did not change significantly (P > 0.05) after mild (5-s treatment at 13 cm) and moderate (30-s treatment at 8 cm) treatments. Significant differences (P < 0.05) in color parameters were observed after treatments of both unpackaged and packaged samples. Packaging material was also analyzed for mechanical properties. The elastic modulus, yield strength, percent elongation at yield point, maximum tensile strength, and percent elongation at break did not change significantly (P > 0.05) after mild treatment. Overall, this study demonstrated that pulsed UV-light has a potential to decontaminate ready-to-eat (RTE) poultry-based food products. PMID:19799670

    In meat processing, powdered ingredients are preferred to liquids because of ease of handling, mixing, and storing. This study was conducted to assess Listeria monocytogenes inhibition and the physicochemical and organoleptic characteristics of frankfurters that were prepared with organic acid salts as spray-dried powders (sodium lactate-sodium acetate, sodium lactate-sodium acetate-sodium diacetate, and potassium acetate-potassium diacetate) or liquids (sodium lactate, sodium lactate-sodium diacetate, potassium lactate, and potassium lactate-sodium diacetate). Full-sodium (1.8% salt) and low-sodium (1.0% salt) frankfurters were prepared according to 10 and 5 different formulations (n = 3), respectively, and were dip inoculated with a six-strain cocktail of L. monocytogenes (∼4 log CFU/g). Populations of Listeria and mesophilic aerobic bacteria were quantified during storage at 4, 7, and 10°C for up to 90 days. Four powder and two liquid full-sodium formulations and one powder low-sodium formulation, all of which contained diacetate except for 1% sodium lactate-sodium acetate powder, completely inhibited Listeria growth at 4°C. However, Listeria grew in full-sodium formulations at 10°C and in low-sodium formulations at 7 and 10°C except for the formulation containing 0.8% potassium acetate-0.2% potassium diacetate powder. All formulations were similar in terms of water activity, cooking yield, moisture, and protein content. Sodium content and pH were affected by the concentrations of sodium and diacetate, respectively. Frankfurter appearance, texture, flavor, and overall acceptability were similar (P > 0.05) regardless of the formulation, except for flavor and overall acceptability of the low-sodium formulation containing potassium acetate-potassium diacetate. Based on these findings, cosprayed powders appear to be a viable alternative to current liquid inhibitors for control of Listeria in processed meats. PMID:23992500

    In the framework of the MOZAIC-IAGOS program, ozone and carbon monoxide vertical profiles are available since 1994 and 2002, respectively. This study investigates the variability and trends of both species at several tropospheric layers above the Frankfurt and Munich airports where about 21 600 flights have been performed over the 1994-2012 period, which represents the densest dataset in the world (about 75 flights per month on average). Over that period, most mean ozone trends are positive but insignificant at a 95 % confidence level, except in winter where significant upward trends (around +0.38 ± 0.24 ppb yr-1) are found. Conversely, a significant increase of annual background ozone is highlighted, mostly during winter and autumn. Mean annual ozone trends increase with altitude, the largest increase being found in summer due to a noticeable decrease of highest ozone concentrations observed in the lower troposphere during the second half period. Over the 2002-2012 period, most mean CO trends are significantly negative, the decrease being higher in the lower troposphere compared to the mid- and upper troposphere with again, major differences in summer. Trends in the ozone seasonal cycle are also investigated, with a focus on the phase. Ozone maxima occur earlier and earlier with a shift around -10.6 ± 2.9 days decade-1 in the lower troposphere, in agreement with previous studies. The analysis of other ozone datasets in Europe (including surface stations and ozone soundings) confirms this trend, but highlights strong heterogeneities in the phase change. Interestingly, this shift is shown to decrease with altitude, with trends of -4.3 ± 2.4 and -2.0 ± 1.7 days decade-1 in the mid- and upper troposphere, respectively. The geographic origin of the air masses sampled by aircraft is analysed with FLEXPART backward simulations and suggests, together with trends and phase changes results, that an increase of the Asian contribution to ozone in the upper troposphere may

    Introduction A multicomponent, evidence-based and interdisciplinary Patient Blood Management (PBM) program was introduced at the University Hospital Frankfurt in July 2013. The implementation strategy included practical and tactical components aimed to increase knowledge on the risks of preoperative anemia, to standardize hemotherapy, and to facilitate PBM components. Methods This article analyzes barriers to PBM implementation and outlines a strategy to introduce and manifest PBM. The effects in Frankfurt were measured in a before and after questionnaire study distributed among groups of physicians immediately before and 1 year after PBM implementation. Results 142 clinicians completed the questionnaire in July 2013 and 101 clinicians in August 2014. Absolute certainty that the treatment of preoperative anemia favorably influences morbidity and mortality rose from 25 to 37%. Transfusion behavior seems to have been affected: In 2014, 56% of clinicians stated that they clinically reassess the patient and analyze hemoglobin following each single red blood cell unit compared to only 38% stating this in 2013. Conclusion These results show that our implementation strategy was effective in changing physicians' risk perception, attitude, and knowledge on PBM principles. Our experience highlights key success factors for the implementation of a comprehensive PBM program. PMID:26019704

    Changes in advection and dispersion caused by retardation and degradation were studied at the landfill site "Monte Scherbelino" near Frankfurt/Main, Germany. In terms of groundwater transport, the site is considered as non-steady state and the effect of retardation and degradation on advective-dispersive transport is pivotal. By applying a technique named as "breakthrough stage analysis (BTSA)", ratios of conservative and reactive compounds were determined along specific flow paths. Depth-specific samples were also collected during this study. Results were evaluated using reference graphs. The data set consists of long-term groundwater quality monitoring data including major ions, field parameters, heavy metals, adsorbable organic halides (AOX) and some organic trace compounds. The data set consists of hydrochemical analyses from 1968 until the construction of a cut-off trench in 1995. The BTSA tool opens additional possibilities for interpretation of groundwater plumes from landfill leachates beyond numerical transport models.

    The safety of ready-to-eat meat products such as frankfurters can be enhanced by treating with approved antimicrobial substances to control the growth of Listeria monocytogenes. We evaluated the effectiveness of acidic calcium sulfate with propionic and lactic acid, potassium lactate, or lactic acid postprocessing dipping solutions to control L. monocytogenes inoculated (ca. 10(8) CFU/ml) onto the surface of frankfurters with or without potassium lactate and stored in vacuum packages at 4.5 degrees C for up to 12 weeks. Two frankfurter formulations were manufactured without (control) or with potassium lactate (KL, 3.3% of a 60% [wt/wt] commercially available syrup). After cooking, chilling, and peeling, each batch was divided into inoculated (four strains of L. monocytogenes mixture) and noninoculated groups. Each group was treated with four different dips: (i) control (saline solution), (ii) acidic calcium sulfate with propionic and lactic acid (ACS, 1:2 water), (iii) KL, or (iv) lactic acid (LA, 3.4% of a 88% [wt/wt] commercially available syrup) for 30 s. Noninoculated frankfurters were periodically analyzed for pH, water activity, residual nitrite, and aerobic plate counts (APCs), and L. monocytogenes counts (modified Oxford medium) were determined on inoculated samples. Surface APC counts remained at or near the lower limit of detection (<2 log CFU per frank) on franks with or without KL and treated with ACS or LA throughout 12 weeks at 4.5 degrees C. L. monoctogenes counts remained at the minimum level of detection on all franks treated with the ACS dip, which indicated a residual bactericidal effect when L. monocytogenes populations were monitored over 12 weeks. L. monocytogenes numbers were also reduced, but not to the same degree in franks made without or with KL and treated with LA. These results revealed the effectiveness of ACS (bactericidal effect) or LA (bacteriostatic effect) as postprocessing dipping solutions to inhibit or control the growth of L

    The Frankfurt Biosphere Model (FBM), a mechanistic and prognostic compartment model of the terrestrial biosphere, has been developed to simulate the carbon exchange fluxes between the vegetation and the atmosphere with a spatial resolution of 0.5{degree} x 0.5{degree} on a global scale. In this contribution the authors use the FBM to assess the possible changes in the response of the northern forest biomes under a future 2{times}CO{sub 2} climate. The development of these ecosystems from its initial seedling state to its climax state is simulated under different climatic conditions. The 2{times}CO{sub 2} climate for these simulations was provided by the GCM of the MPI fuer Meteorologie in Hamburg (ECHAM). The differences in vegetation growth under contemporary and future climate can be assessed by performing three model runs with the same parameterization but with different driving climatic variables for each vegetation type and location: (1) a simulation run with present climate conditions; (2) a simulation run under 2{times}CO{sub 2} climate conditions; and (3) which is same as (2) but with the assumption of a CO{sub 2} fertilization effect.

    At the regional scale, various uncertainties persist on the ozone budget in the troposphere, including the relative contributions of local formation, long-range transport or stratospheric intrusions. In the framework of the MOZAIC-IAGOS program, a large amount of ozone and carbon monoxide data is collected in the troposphere by commercial aircraft since 1994 and 2002, respectively. This work investigates vertical profiles (take-offs, landings) around Frankfurt and Munich airports in Central/Western Europe during the 1994-2011 period. In the troposphere, observations indicate no significant trend for ozone, contrary to CO that is clearly decreasing. A focus is also made on the evolution of the tropospheric ozone seasonal cycle (baseline, amplitude and phase). As most ozone sources (e.g. local formation, long-range transport) have their own seasonality, investigating changes in the ozone seasonality and trends is expected to provide valuable information on their apportionment. The analysis will take advantage of the availability of measurements at various altitudes to put light on the current evolution of ozone variability at different distances from local precursors emissions. Transport patterns at the hemispheric scale are also investigated, showing an inter-annual variability that may explain a part of the inter-annual variability recorded on concentrations.

    At the University of Frankfurt a high current proton source has been developed and tested for the FRANZ-Project [U. Ratzinger, L. P. Chau, O. Meusel, A. Schempp, K. Volk, M. Heil, F. Käppeler, and R. Stieglitz, “Intense pulsed neutron source FRANZ in the 1–500 keV range,” ICANS-XVIII Proceedings, Dongguan, April 2007, p. 210]. The ion source is a filament driven arc discharge ion source. The new design consists of a plasma generator, equipped with a filter magnet to produce nearly pure proton beams (92 %), and a compact triode extraction system. The beam current density has been enhanced up to 521 mA/cm{sup 2}. Using an emission opening radius of 4 mm, a proton beam current of 240 mA at 50 keV beam energy in continuous wave mode (cw) has been extracted. This paper will present the current status of the proton source including experimental results of detailed investigations of the beam composition in dependence of different plasma parameters. Both, cw and pulsed mode were studied. Furthermore, the performance of the ion source was studied with deuterium as working gas.

    The Frankfurt Biosphere Model (FBM), a mechanistic, seasonal and prognostic compartment model of the terrestrial biosphere, has been developed in recent years to simulate the carbon exchange fluxes between the vegetation and the atmosphere with a spatial resolution of 0.5{degree} x 0.5{degree} on a global scale. In this contribution the authors use the FBM to assess the possible changes in the transient response of the northern forest biomes under a future 2 {times} CO{sub 2} climate. The development of these ecosystems from its initial seedling state to its climax state is simulated under different climatic conditions. In their simulations the 2 {times} CO{sub 2} climate provided by the GCM of the MPI fuer Meteorologie in Hamburg (ECHAM) is used. The differences in vegetation`s growth under contemporary and future climate can be assessed by performing two model runs with the same parameterization but with different driving climatic variables for each vegetation type and location.

    Beef, buffalo, and pork adulteration in the food chain is an emerging and sensitive issue. Current molecular techniques to authenticate these species depend on polymerase chain reaction (PCR) assays involving long and single targets which break down under natural decomposition and/or processing treatments. This novel multiplex polymerase chain reaction-restriction fragment length polymorphism assay targeted two different gene sites for each of the bovine, buffalo, and porcine materials. This authentication ensured better security, first through a complementation approach because it is highly unlikely that both sites will be missing under compromised states, and second through molecular fingerprints. Mitochondrial cytochrome b and ND5 genes were targeted, and all targets (73, 90, 106, 120, 138, and 146 bp) were stable under extreme boiling and autoclaving treatments. Target specificity and authenticity were ensured through cross-amplification reaction and restriction digestion of PCR products with AluI, EciI, FatI, and CviKI-1 enzymes. A survey of Malaysian frankfurter products revealed rampant substitution of beef with buffalo but purity in porcine materials. PMID:27501408

    Mutations in the genome of HIV-1 can compromise the success of antiretroviral treatments (ARTs) in HIV-1-infected individuals. The Frankfurt HIV Cohort Study Resistance Database (FHCS-RD) has previously documented a decline in the burden of resistance-associated mutations (RAMs) following the implementation of several new antiretroviral therapy regimens in 2007. In the current study, the annual burden of RAMs documented in the FHCS-RD in 2005-2013 was set in relation to the annual number of all cohort patients, drug regimens, available resistance tests, and prevalence for each RAM on relevant codons of reverse transcriptase (RT) and protease (PR) genes. A specific focus was put on the prevalence of the tenofovir disoproxil fumarate (TDF) signature mutation K65R in HIV-1 RT in relation to the application of TDF within ART. Between 2005 and 2012, a total of 4423 HIV genotyping data sets from 4509 patients were analysed. All mutations show a consistent decline, and the most impressive decrease was observed for thymidine analogue mutations (TAMs). The frequency of non-TAMs and PR mutations also decreased, but generally to a lower extent. The prevalence of K65R decreased from 2.6 % in 2005 to 0.2 % in 2012 despite increased use of TDF-containing ART. Both the improved strategic use of TDF in ARTs and generally more effective ART regimens may have resulted in decreasing RAM prevalences in FHCS-RD since 2007. These trends challenge the cost-effectiveness of resistance testing prior to failing ART. PMID:26746222

    Companies can voluntarily participate in matters of regional developments, thereby accepting responsibility on a regional level. Referring to the concept of Corporate Social Responsibility (CSR), the term Corporate Regional Responsibility (CRR) is used to describe this behavior. Moreover, companies can form a CRR-corporation with other companies in order to take over a collective CRR. So far, the motives of companies for exercising collective CRR are unknown, thus, corporate resources can not be mobilized and utilized efficiently for regional developments. This article explores the subject of collective CRR and illustrates CRR motives using the example of the two CRR-cooperations Initiativkreis Ruhr and Wirtschaftsinitiative FrankfurtRheinMain.

    A 2MeV proton beam will produce a quasi-Maxwellian neutron spectrum of around 30 keV by the 7Li(p, n)7Be reaction. The experiments are mainly focused on the measurement of differential neutron capture cross sections relevant for the astrophysical s-process in nuclear synthesis. Moreover, proton capture cross sections for the astrophysical p-process can be measured directly with the proton beam. For an efficient time of flight measurement of the neutron energies along the 0.7 m long drift from the Li-target to the sample, 1ns short, intense proton pulses are needed at the target. Additionally, to reach 107 n/cm2/s at the sample, a pulse repetition rate of 250 kHz is intended. After completion and successful running in, FRANZ will become a user facility with internal and external users. The 120 kV injector terminal and the 200mA proton source as well as the low-energy beam transport section and the FRANZ cave have been realized successfully. The 1.9 MV RF accelerator consists of a combined 4-Rod-RFQ/IH-DTL-resonator and is in the RF tuning and power testing phase. The 2 MeV transport and rebuncher section is ready for installation. In a first step FRANZ will offer experimental areas for neutron activation experiments and for proton beam experiments, as mentioned above. From the accelerator physics point of view, FRANZ will be an excellent facility for high current beam investigations and for beam wall interaction studies.

    Several studies reported improved outcomes of adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) treated with pediatric-based ALL regimens. This prompted the prospective investigation of a pediatric Augmented Berlin-Frankfurt-Münster (ABFM) regimen, and its comparison with hyper-fractionated cyclophosphamide, vincristine, Adriamycin, and dexamethasone (hyper-CVAD) in AYA patients. One hundred and six AYA patients (median age 22 years) with Philadelphia chromosome- (Ph) negative ALL received ABFM from October 2006 through March 2014. Their outcome was compared to 102 AYA patients (median age 27 years), treated with hyper-CVAD at our institution. The complete remission (CR) rate was 93% with ABFM and 98% with hyper-CVAD. The 5-year complete remission duration (CRD) were 53 and 55%, respectively (P = 0.98). The 5-year overall survival (OS) rates were 60 and 60%, respectively. The MRD status on Day 29 and Day 84 of therapy was predictive of long-term outcomes on both ABFM and hyper-CVAD. Severe regimen toxicities with ABFM included hepatotoxicity in 41%, pancreatitis in 11%, osteonecrosis in 9%, and thrombosis in 19%. Myelosuppression-associated complications were most significant with hyper-CVAD. In summary, ABFM and hyper-CVAD resulted in similar efficacy outcomes, but were associated with different toxicity profiles, asparaginase-related with ABFM and myelosuppression-related with hyper-CVAD.

    In pediatric acute myeloid leukemia (AML), cytogenetic abnormalities are strong indicators of prognosis. Some recurrent cytogenetic abnormalities, such as t(8;16)(p11;p13), are so rare that collaborative studies are required to define their prognostic impact. We collected the clinical characteristics, morphology, and immunophenotypes of 62 pediatric AML patients with t(8;16)(p11;p13) from 18 countries participating in the International Berlin-Frankfurt-Münster (I-BFM) AML study group. We used the AML-BFM cohort diagnosed from 1995-2005 (n = 543) as a reference cohort. Median age of the pediatric t(8;16)(p11;p13) AML patients was significantly lower (1.2 years). The majority (97%) had M4-M5 French-American-British type, significantly different from the reference cohort. Erythrophagocytosis (70%), leukemia cutis (58%), and disseminated intravascular coagulation (39%) occurred frequently. Strikingly, spontaneous remissions occurred in 7 neonates with t(8;16)(p11;p13), of whom 3 remain in continuous remission. The 5-year overall survival of patients diagnosed after 1993 was 59%, similar to the reference cohort (P = .14). Gene expression profiles of t(8;16)(p11;p13) pediatric AML cases clustered close to, but distinct from, MLL-rearranged AML. Highly expressed genes included HOXA11, HOXA10, RET, PERP, and GGA2. In conclusion, pediatric t(8;16)(p11;p13) AML is a rare entity defined by a unique gene expression signature and distinct clinical features in whom spontaneous remissions occur in a subset of neonatal cases.

Based on the Autonomous Flying Platforms for Atmospheric and Earth Surface Observations project (APAESO) of the Energy, Environment and Water Research Center (EEWRC) at the Cyprus Institute (APAESO is co-financed by the European Development Fund and the Republic of Cyprus through the Cyprus Research Promotion Foundation: ΝΕΑ ΥΠΟΔΟΜΗ/ΝΕΚΥΠ/0308/09), we have acquired four CRUISERS (ET-Air, Slovakia) as UAS platforms and a substantial range of scientific instruments to be employed on these platforms. The APAESO platforms are aimed at the dual purpose of carrying out atmospheric and earth-surface observations in the (Eastern) Mediterranean They will enable 3D measurements for determining physical, chemical and radiative atmospheric properties, aerosol and dust concentrations and atmospheric dynamics as well as 2D investigations into land management practices, vegetation and agricultural mapping, contaminant detection and the monitoring and assessment of hydrological parameters and processes of a given region at high spatial resolution. Currently, we are building up an Unmanned Airplane Facility at CyI. In the process of reaching full operational capacity, we have initiated and carried out first test missions involving highly specialized and specifically adapted instrumentation for atmospheric investigations. The first scientific mission involves the employment of a DOAS-system (Differential Optical Absorption Spectroscopy) in cooperation with colleagues from Heidelberg and Mainz, Germany and has been successfully completed.

    An intense field campaign from the Ice Nuclei Research Unit (INUIT) was performed in January and February of 2013 at the High-Alpine Research Station Jungfraujoch (3580 m a.s.l., Switzerland). Main goal was the assessment of microphysical and chemical properties of free-tropospheric ice-nucelating particles. The ice-nucleating particles were discriminated from the total aerosol with the 'Fast Ice Nucleation CHamber' (FINCH; University Frankfurt) and the 'Ice-Selective Inlet' (ISI, Paul Scherer Institute) followed by a pumped counter-stream virtual impactor. The separated ice-nucleating particles were then collected with a nozzle-type impactor. With the 'FRankfurt Ice nuclei Deposition freezinG Experiment' (FRIDGE), aerosol particles are sampled on a silicon wafer, which is than exposed to ice-activating conditions in a static diffusion chamber. The locations of the growing ice crystals are recorded for later analysis. Finally, with the ICE Counter-stream Virtual Impactor (ICE-CVI) atmospheric ice crystals are separated from the total aerosol and their water content is evaporated to retain the ice residual particles, which are then collected also by impactor sampling. All samples were analyzed in a high-resolution scanning electron microscope. By this method, for each particle its size, morphology, mixing-state and chemical composition is obtained. In total approximately 1700 ice nucleating particles were analyzed. Based on their chemical composition, the particles were classified into seven groups: silicates, metal oxides, Ca-rich particles, (aged) sea-salt, soot, sulphates and carbonaceous matter. Sea-salt is considered as artifact and is not regarded as ice nuclei here. The most frequent ice nucleating particles/ice residuals at the Jungfraujoch station are silicates > carbonaceous particles > metal oxides. Calcium-rich particles and soot play a minor role. Similar results are obtained by quasi-parallel measurements with an online single particle laser ablation

    Park, S. K.; Chung, U. S.; Jung, K. J.; Park, J. H.

    2003-02-24

    Korea Research Reactor 1 (KRR-1), the first research reactor in Korea, has been operated since 1962, and the second one, Korea Research Reactor 2 (KRR-2) since 1972. The operation of both of them was phased out in 1995 due to their lifetime and operation of the new and more powerful research reactor, HANARO (High-flux Advanced Neutron Application Reactor; 30MW). Both are TRIGA Pool type reactors in which the cores are small self-contained units sitting in tanks filled with cooling water. The KRR-1 is a TRIGA Mark II, which could operate at a level of up to 250 kW. The second one, the KRR-2 is a TRIGA Mark III, which could operate at a level of up 2,000 kW. The decontamination and decommissioning (D & D) project of these two research reactors, the first D & D project in Korea, was started in January 1997 and will be completed to stage 3 by 2008. The aim of this decommissioning program is to decommission the KRR-1 & 2 reactors and to decontaminate the residual building structure s and the site to release them as unrestricted areas. KAERI (Korea Atomic Energy Research Institute) submitted the decommissioning plan and the environmental impact assessment reports to the Ministry of Science and Technology (MOST) for the license in December 1998, and was approved in November 2000.

    There are currently 284 research reactors in operation, and 12 under construction around the world. Of the operating reactors, nearly two-thirds are used exclusively for research, and the rest for a variety of purposes, including training, testing, and critical assembly. For more than 50 years, research reactor programs have contributed greatly to the scientific and educational communities. Today, six of the world`s research reactors are being shut down, three of which are in the USA. With government budget constraints and the growing proliferation concerns surrounding the use of highly enriched uranium in some of these reactors, the future of nuclear research could be impacted.

    THERE IS an increasing recognition of the importance of involving patients, family members and the public in health research. This involvement is commonly termed patient and public involvement (PPI) and refers to an 'active partnership between the public and researchers'. This is different to children, young people and/or parents being participants in a research project. Effective PPI ensures that research does not just focus on professionally driven priorities, but addresses what actually matters to children, young people and their families. PMID:27156413

  7. Why do research on research?

    PubMed

    Anderson, J; Evered, D C

    1986-10-01

    The importance of research evaluation is now well recognised in some quarters but this activity is being looked upon as essentially negative by others. We believe this view to be mistaken. The case for investing some money in research evaluation is essentially a very straightforward one. It is clear that a significant fraction of the money spent on research will be wasted (ie, will produce no usable data--positive or negative--on any time-scale and will be of no educational or training value). The problem is, and has always been, that there is no way of knowing in advance which fraction of the resources will be wasted. That is the nature of research and we would not argue that it could or should be otherwise. Research is about exploration and discovery and it is inevitable that some scientific endeavours will be fruitless. Research evaluation can help to minimise resource wastage and thus the case for conducting research on research is entirely positive. Analytical techniques are available to examine the ways in which we train research workers, fund research workers, and assess research outputs; and these should be applied with a view to improving the system. There is also a strong case for setting up an effective mechanism for strategic forecasting and planning, and an urgent need to take a radical look at the entire range of biomedical research activities in the UK. It is essential that the research community should take steps to evaluate its performance and adopt a positive approach to planning. If it does not do so, assessments will be made by those without a fundamental understanding of the nature of the enterprise, and the prospects for any further increases in public support would appear to be bleak.

    THE THEME of this edition of Nurse Researcher, 'disseminating research', is pertinent to researchers across the career spectrum and tackles two important issues: open access publishing and originality in PhD research. In the first paper, Suzanne Fredericks examines and contrasts two models of open access publishing, revealing some notable advantages of 'green' open access, achieved through repositories, as opposed to the more well-known 'gold' open access offered by journals ( Fredericks 2015 ). In the second paper, Paul Gill and Gina Dolan discuss originality in PhD studies, exploring the nature of the concept and how doctoral students can demonstrate originality, which is an essential consideration in their research dissemination activities as well as their thesis preparation ( Gill and Dolan 2015 ).

    Bioprocessing research integrates a wide variety of fields and disciplines to achieve a process with economic and environmental advantages over conventional chemical processing. Specific fields of bioprocessing research typically involve biocatalysis development to identify and improve the enzyme or microorganism, biocatalysis production and retention to provide and maintain biocatalytic activity at the lowest possible cost, raw material treatment and selection to provide low cost substrates that are amenable to biological transformation, reactor design, downstream processing to purify the desired product and recycle nutrients or biocatalysts, and, finally, system integration. The papers presented in this session address many of the above issues in bioprocessing research.

    2008-12-01

    This issue of JERHRE focuses on two topics that have been largely ignored-trust in the human research industry and structural factors that affect the efficacy of ethical review of human research (i.e., factors that are not under the control of ethics committee members, such as the funding of committee resources and the provision of clear workable regulations). Trust and an adequate ethical infrastructure are integral to one another. Ethical capacity does not reside with an ethics committee alone, but springs from four foundations of ethical research. It derives from (a) national bodies that regulate research and clarify the ethical principles that are promulgated, (b) the institutional research administrations that finance and build the needed infrastructure, (c) the ethics committees that struggle to operate within this system, and (d) the individual disciplines and departments that should work collaboratively with investigators and ethics committees to provide needed expertise. Research on trust and adequate ethical review needs to be mindful of the larger dynamic system within which ethical oversight occurs, and how failure of any of its four major components weakens its other components.

    Philip Morris research center scientists use a computer program called CECTRP, for Chemical Equilibrium Composition and Transport Properties, to gain insight into the behavior of atoms as they progress along the reaction pathway. Use of the program lets the scientist accurately predict the behavior of a given molecule or group of molecules. Computer generated data must be checked by laboratory experiment, but the use of CECTRP saves the researchers hundreds of hours of laboratory time since experiments must run only to validate the computer's prediction. Philip Morris estimates that had CECTRP not been available, at least two man years would have been required to develop a program to perform similar free energy calculations.

  12. Riblet Research

    NASA Technical Reports Server (NTRS)

    1985-01-01

    Research at Langley on skin friction drag was described in Tech Briefs. 3M engineers suggested to Langley that grooves molded into a lightweight plastic film with adhesive backing and pressed on an airplane would be simpler than cutting grooves directly onto the surface. Boeing became involved and tested the "riblet" on an olympic rowing shell; the US won a silver medal. Based on the riblet-like projections on shark's skins, the technology may provide a 5 percent fuel saving for airplanes. Product is no longer commercially available.

    1987-01-01

    The principle focus of one of the RICIS (Research Institute for Computing and Information Systems) components is computer systems and software engineering in-the-large of the lifecycle of large, complex, distributed systems which: (1) evolve incrementally over a long time; (2) contain non-stop components; and (3) must simultaneously satisfy a prioritized balance of mission and safety critical requirements at run time. This focus is extremely important because of the contribution of the scaling direction problem to the current software crisis. The Computer Systems and Software Engineering (CSSE) component addresses the lifestyle issues of three environments: host, integration, and target.

  16. Structures research

    NASA Technical Reports Server (NTRS)

    Abu-Saba, Elias; Mcginley, Williams; Shen, Ji-Yao

    1992-01-01

    The main objective of the structures group is to provide quality aerospace research with the Center for Aerospace Research - A NASA Center for Excellence at North Carolina Agricultural and Technical State University. The group includes dedicated faculty and students who have a proven record in the area of structures, in particular space structures. The participating faculty developed accurate mathematical models and effective computational algorithms to characterize the flexibility parameters of joint dominated beam-truss structures. Both experimental and theoretical modelling has been applied to the dynamic mode shapes and mode frequencies for a large truss system. During the past few months, the above procedures has been applied to the hypersonic transport plane model. The plane structure has been modeled as a lumped mass system by Doctor Abu-Saba while Doctor Shen applied the transfer matrix method with a piecewise continuous Timoshenko tapered beam model. Results from both procedures compare favorably with those obtained using the finite element method. These two methods are more compact and require less computer time than the finite element method. The group intends to perform experiments on structural systems including the hypersonic plane model to verify the results from the theoretical models.

  17. Atomic research

    NASA Technical Reports Server (NTRS)

    Hadaway, James B.; Connatser, Robert; Cothren, Bobby; Johnson, R. B.

    1993-01-01

    Work performed by the University of Alabama in Huntsville's (UAH) Center for Applied Optics (CAO) entitled Atomic Research is documented. Atomic oxygen (AO) effects on materials have long been a critical concern in designing spacecraft to withstand exposure to the Low Earth Orbit (LEO) environment. The objective of this research effort was to provide technical expertise in the design of instrumentation and experimental techniques for analyzing materials exposed to atomic oxygen in accelerated testing at NASA/MSFC. Such testing was required to answer fundamental questions concerning Space Station Freedom (SSF) candidate materials and materials exposed to atomic oxygen aboard the Long-Duration Exposure Facility (LDEF). The primary UAH task was to provide technical design, review, and analysis to MSFC in the development of a state-of-the-art 5eV atomic oxygen beam facility required to simulate the RAM-induced low earth orbit (LEO) AO environment. This development was to be accomplished primarily at NASA/MSFC. In support of this task, contamination effects and ultraviolet (UV) simulation testing was also to be carried out using NASA/MSFC facilities. Any materials analysis of LDEF samples was to be accomplished at UAH.

  18. Heart Research

    NASA Technical Reports Server (NTRS)

    1991-01-01

    James Antaki and a group of researchers from the University of Pittsburgh School of Medicine used many elements of the Technology Utilization Program while looking for a way to visualize and track material points within the heart muscle. What they needed were tiny artificial "eggs" containing copper sulfate solution, small enough (about 2 mm in diameter) that they would not injure the heart, and large enough to be seen in Magnetic Resonance Imaging (MRI) images; they also had to be biocompatible and tough enough to withstand the beating of the muscle. The group could not make nor buy sufficient containers. After reading an article on microspheres in NASA Tech Briefs, and a complete set of reports on microencapsulation from the Jet Propulsion Laboratory (JPL), JPL put Antaki in touch with Dr.Taylor Wang of Vanderbilt University who helped construct the myocardial markers. The research is expected to lead to improved understanding of how the heart works and what takes place when it fails.

  1. Research sensors

    NASA Astrophysics Data System (ADS)

    Englund, David R.

    1988-05-01

    The work described is part of a program (Englund and Seasholtz, 1988) to develop sensors and sensing techniques for research applications on aircraft turbine engines. In general, the sensors are used to measure the environment at a given location within a turbine engine or to measure the response of an engine component to the imposed environment. Locations of concern are generally in the gas path and, for the most part, are within the hot section. Specific parameters of concern are dynamic gas temperature, heat flux, airfoil surface temperature, and strain on airfoils and combustor liners. To minimize the intrusiveness of surface-mounted sensors, a considerable effort was expended to develop thin-film sensors for surface temperature, strain, and heat flux measurements. In addition, an optical system for viewing the interior of an operating combustor was developed. Most of the work described is sufficiently advanced that the sensors were used and useful data were obtained. The notable exception is the work to develop a high-temperature static strain measuring capability; the work is still in progress.

  3. Research Report

    NASA Astrophysics Data System (ADS)

    Dawes, Lyn

    2004-06-01

    This paper examines what is important about talk between learners during school science and, having identified this, suggests how we can ensure that what we consider important happens. By looking at the interaction between teachers and learners talking about science, it is possible to indicate ways in which learners can be helped to continue this learning conversation with one another when teacher support is withdrawn. Strategies for teaching and learning are examined. The paper reports on the findings of a research project designed to teach children how to negotiate their ideas about science concepts through rational dialogue. Children's development of scientific concepts in classrooms is undertaken through structured activity and mediated through oral language. Children must move forward simultaneously in their use of specialized vocabulary and in their understanding of current scientific explanations, models and ideas. New language and new ways of using language are learned by doing, which means for children, primarily speaking and listening. Children's understanding of science can benefit from teaching them to understand that spoken language is a powerful tool for thinking together.

    In the field of space life sciences, the demand of an interdisciplinary and specific training of young researchers is high due to the complex interaction of medical, biological, physical, technical and other questions. The Helmholtz Space Life Sciences Research School (SpaceLife) offers an excellent interdisciplinary training for doctoral students from different fields (biology, biochemistry, biotechnology, physics, psychology, nutrition or sports sciences and related fields) and any country. SpaceLife is coordinated by the Institute of Aerospace Medicine at the German Aerospace Center (DLR) in Cologne. The German Universities in Kiel, Bonn, Aachen, Regensburg, Magdeburg and Berlin, and the German Sports University (DSHS) in Cologne are members of SpaceLife. The Universities of Erlangen-Nürnberg, Frankfurt, Hohenheim, and the Beihang University in Beijing are associated partners. In each generation, up to 25 students can participate in the three-year program. Students learn to develop integrated concepts to solve health issues in human spaceflight and in related disease patterns on Earth, and to further explore the requirements for life in extreme environments, enabling a better understanding of the ecosystem Earth and the search for life on other planets in unmanned and manned missions. The doctoral candidates are coached by two specialist supervisors from DLR and the partner university, and a mentor. All students attend lectures in different subfields of space life sciences to attain an overview of the field: radiation and gravitational biology, astrobiology and space physiology, including psychological aspects of short and long term space missions. Seminars, advanced lectures, laboratory courses and stays at labs at the partner institutions or abroad are offered as elective course and will provide in-depth knowledge of the chosen subfield or allow to appropriate innovative methods. In Journal Clubs of the participating working groups, doctoral students learn

  15. Connecting Research and Researchers: ORCID Identifiers (Invited)

    NASA Astrophysics Data System (ADS)

    Haak, L.; Bryant, R.

    2013-12-01

    Lack of standards for identification of researchers is a major challenge for the research community. It is difficult not only to unambiguously associate researchers with their own work, but also to track use and re-use of those works. The goal of ORCID (orcid.org) is to connect research with researchers, ultimately saving researchers time in entering data, improving discoverability, and facilitating the flow of research information and data re-use. ORCID is a community-driven non-profit organization that provides an open registry of unique persistent identifiers for researchers. We work collaboratively with the research community to embed these identifiers in research workflows, including manuscript submission, grant application, and data set deposit. In this presentation, we will provide an overview of ORCID, an in particular how it is being used as a switchboard to connect existing but fragmented researcher identifiers. ORCID also provides researchers search and link tools to link their ORCID identifier to their existing datasets, grants, other research works, and an automated method to link new works to their identifier. ORCID is fundamental to solving the name ambiguity problem for researchers and scholars. Together with unique and persistent identifiers for publications, data sets, and research samples, ORCID is an essential underpinning needed to support interoperability between research systems.

    The research plan was initially intended to contain the information needed to evaluate the U.S. Environmental Protection Agency (EPA) Arctic Contaminant Research Program (ACRP). The scientific aspects of the proposed research form the main body of the document and focus on objectives of the specific research components, current literature, approach, and rationale. The ACRP has three major components: (1) extensive sampling of lichens, mosses, and soils to provide a spatial understanding of the status and extent of contaminants present in arctic ecosystems, (2) lake sediment research to evaluate the source and history of arctic contaminant inputs, and (3) food web research to evaluate the possible effects of atmospherically transported pollutants on arctic food webs. The research plan will be used to provide a framework for the ACRP, based on the preliminary studies done to date and will be implemented over the next five years. The Program will undergo additional peer reviews at two-year intervals in the future.

The research is financed primarily by the Ministry of Trade and Industry (KTM), the Finnish Center for Radiation and Nuclear Safety (STUK), and VTT itself. Other research institutes, utilities, and industry also contribute to many projects.

  8. Ethical suicide research: a survey of researchers.

    Research is needed to better understand and respond effectively to people who are suicidal. Involving people who are suicidal in research poses some ethical and pragmatic problems. The ethical problems and difficulties in obtaining approval to involve people who are suicidal in research has contributed to the current paucity of research that explores the suicidal experience. To explore some of these problems, a web-based survey of suicide researchers was undertaken. Researchers identified from published reports were contacted by email and invited to participate in a web-based survey. Researchers were asked to describe any problems they encountered, how ethical problems were negotiated or resolved, and any advice received from human research ethics committees. The main problems identified were accessing the population, maintaining confidentiality, the extent of care owed by the researcher to participants, and the facilitation of support to participants. As with clinical practice, ethical research involving people who are suicidal involves a process of sensitive engagement, and careful consideration and remediation of risk. PMID:19125782

    From 2004 to 2012, the German Ministry of Education and Research (BMBF) established its first funding programme for the promotion of prevention research. 60 projects on primary prevention and health promotion and the meta-project entitled "Cooperation for Sustainable Prevention Research" (KNP) received BMBF grants under this programme during this period. The experience and knowledge gained and recommendations arising from the research funded under this programme are compiled in memorandum format. The "Memorandum on Prevention Research - Research Areas and Methods" highlights 5 research areas that are considered to be especially relevant from the perspective of the involved scientists and practice partners.The promotion of structural development and sustainability enhancement in disease prevention and health promotion are central areas that should branch out from existing nuclei of crystallization. Improving the health competence of the population and of specific subpopulations is another major area. Research in these areas should contribute to the development of theoretical concepts and to the empirical testing of these concepts. The transfer of knowledge for effective use of developed disease prevention and health promotion programmes and measures is still a scarcely researched area. Among other things, studies of the transfer of programmes from one context to another, analyses of the coop-eration between politics and science, and the continued theoretical and conceptual development of transfer research are needed. Long-term data on the effects of intervention studies are also needed for proper evaluation of sustainability. The latter dem-onstrates the importance of method development in disease prevention and health promotion research as an area that should receive separate funding and support. This research should include, in particular, studies of the efficacy of complex interventions, health economic analyses, and participative health research. PMID:23165608
