Impedanzrohr

description: Das Impedanzmessrohr ist ein weit verbreitetes Messsystem für die Bestimmung akustischer Materialeigenschaften. Dieses erfordert jedoch hoch genaue akustische Messhardware. In der vorliegenden Arbeit soll diese Art von Messungen durch die Verwendung günstiger Komponenten zugänglicher gemacht werden. Dafür werden die gängigen und standardisierten Messmethoden um zusätzliche Mikrofone erweitert, mit dem Ziel, durch geeignete Auswertungsalgorithmen eine ähnliche Messgenauigkeit zu erreichen. Einerseits wird die Wellenzahlzerlegung mittels der Methode der kleinster Fehlerquadrate aus den Daten beliebig vieler Mikrofone untersucht. Andererseits werden einzelne Mikrofon-Paare getrennt nach Norm ausgewertet und anschließend, mit Berücksichtigung der zulässigen Frequenzbänder, gemittelt. Die vorgestellten Methoden wurden experimentell anhand von fünfzehn Melaminharzschaum-Proben getestet. Für den Frequenzbereich über 400 Hz wurden kaum Veränderungen, im Vergleich mit den Referenzmessungen festgestellt. Für kleine Signalunterschiede, bei tiefen Frequenzen oder Knotenpunkte, waren die Messungen stark fehleranfällig. Hier liefern die vorgestellten Erweiterungen einen großen Beitrag zur Fehlerreduktion. Die starke Abhängigkeit von Kleinsignalauflösung konnte durch die vorgeschlagenen Algorithmen weitgehend eliminiert werden, zusätzlich werden einige Verbesserungsvorschläge eingebracht, um das Potential der Methoden weiter auszuschöpfen.

description: Fluoroquinolones form a promising family of new bactericidal antimicrobials. Enrofloxacin is the first antimicrobial of this family available to veterinary medicine. Fluoroquinolones share a wide spectrum of acitivity but are most potent against gram-negative bacteria. They have a large volume of distribution and a low binding to plasma proteins, and are active at low concentrations. Compared with many other antimicrobials, they also have the advantage of being active against intracellular pathogens (8). Very few studies have been made of the pharmacokinetics of enrofloxacin in lactating cows. In one report, enrofloxacin was administered intravenously ( IV) or intramuscularly (IM) to three cows (3). After both routes of administration, the concentration of enrofloxacin in milk rapidly exceeded that in plasma. At a dose of 2.5 mg/kg b.w., inhibitory levels against coliform bacteria and most staphylococci(> 0.25 μg/ ml) were obtained in milk for approximately 24 hours. Using the same dose administered subcutaneously (SC), a concentration of 0.06 μg/ml or more was maintained in the serum and tissue of calves for 24 hours (6). The bactericidal action of fluoroquinolones, their wide distribution in tissue and their activity against intracellular pathogens make them attractive for the treatment of staphylococcal mastitis. Enrofloxacin could solve the problem posed by the lack of a pharmacokinetically suitable antimicrobial for coliform mastitis. There are no published data on the efficacy of fluoroquinolones in the treatment of mastitis, except one preliminary report on norfloxacin in dry cow therapy (7).

description: The objective of this study was to determine the highest dose of procaine penicillin G (PPG) which could be administered to allow a withdrawal period of 96 hours in the milk in milking dairy cows. Using two 4x4 latin square designs, two groups of lactating dairy cows (n=4 per group) received 4 different doses (7,000, 14,000, 21,000 and 28,000 IU/kg 20 mL/site of a 300 000 IU/mL of PPG . Each dose was administered once daily for 5 consecutive days to each cow by either the intramuscular (square 1) or subcutaneous route (square 2). Each cow received a new dose every 3 weeks. Milk samples were collected before administration and at 12, 24, 36, 48, 60, 72, 84, 96, 108, 120 and 132 hours following the last day of administration. Concentration of penicillin in milk was measured using a quantitative Bacillus stearothermophilus disc method. For all 4 doses administered via the intramuscular route all the animals (n=4) had milk penicillin concentration less than 0.016 IU/mL by 84 hours. However, the cows that received the PPG via the subcutaneous route had penicillin concentration less than 0.016 IU/mL by 84 hours for the dosage of 7,000, 14,000 and 21,000 IU/kg while the penicillin concentrations remained higher than 0.016 IU/mL for 108 hours after the administration of the 28,000 IU/kg dose. Residual milk concentrations of penicillin were more variable and less predictable than those from the intramuscularly-injected cows. The results of this study indicate that the dose of 21,000 IU/kg is safe with 96 hours withdrawal in milk whichever route of administration.

description: This study was done on 325 dairy farms in Quebec, Canada to estimate S. agalactiae and S. aureus herd infection prevalence and their impact on milk production and quality. A maximum of 3 bulk tank milk sample were collected in each selected farm for bacteriology and somatic cell counting. A questionnaire for evaluation of farm management and mastitis control practices was administered during the first visit. The study reveals a herd infection prevalence for S. agalactiae and S. aureus of 43% and 93.4% respectively; 4.7% are negative to both bacteria. Adoption on a regular basis of teat dipping of all cows and blanket dry cow therapy is 60.8% and 34% respectively. The high prevalence results for S. agalactiae and S. aureus and the poor adoption of basic mastitis control practices give us a basis to improve upon with a mastitis control program.

Year: 1992

description: The concept of disease monitoring in veterinary medicine has been discussed for decades. Its importance becomes more apparent as diseases that cause catastrophic illness are less prevalent and the main health challenge facing the animal production industry is low productivity. Disease monitoring schemes are proposed and discarded on a regular basis. In 1975, an international conference on disease monitoring was held. One of the participants, M.E. Hugh-Jones commented: "At any conference on disease monitoring there is usually one articulate, optimistic speaker who has the perfect system. This computerized philosopher's stone is not quite ready, but within a few months it will be working perfectly, turning mercury into gold. Little more is heard of these schemes, but occassionally an older and wiser man emerges to breifly describe his experiences."(1) With this caveat, the objective of this paper is to describe a system for mastitis monitoring. This system was developed using diagnostic laboratory data as the core information. These data integrate with other record systems to provide a method to monitor herd performance over time and allow interpretation of trends to suggest interventions to improve herd performance.

description: Ultra-cool dwarfs of the L spectral type (Teff=1400-2200K) are known to have dusty atmospheres. Asymmetries of the dwarf surface may arise from rotationally-induced flattening and dust-cloud coverage, and may result in non-zero linear polarisation through dust scattering. We aim to study the heterogeneity of ultra-cool dwarfs' atmospheres and the grain-size effects on the polarisation degree in a sample of nine late M, L and early T dwarfs. We obtain linear polarimetric imaging measurements using FORS1 at the Very Large Telescope, in the Bessel I filter, and for a subset in the Bessel R and the Gunn z filters. We measure a polarisation degree of (0.31+/-0.06)% for LHS102BC. We fail to detect linear polarisation in the rest of our sample, with upper-limits on the polarisation degree of each object of 0.09% to 0.76% (95% CL). For those targets we do not find evidence of large-scale cloud horizontal structure in our data. Together with previous surveys, our results set the fraction of ultra-cool dwarfs with detected linear polarisation to (30+10-6)% (1-sigma). For three brown dwarfs, our observations indicate polarisation degrees different (at the 3-sigma level) than previously reported, giving hints of possible variations. Our results fail to correlate with the current model predictions for ultra-cool dwarf polarisation for a flattening-induced polarisation, or with the variability studies for a polarisation induced by an hetereneous cloud cover. This stresses the intricacy of each of those tasks, but may as well proceed from complex and dynamic atmospheric processes.

description: Drug residues in milk have received much attention in recent months. Not surprisingly, the residue data collected by different groups, as well as the interpretation of its significance to public health, have been widely divergent The publicity generated has caused public concerns about the safety and wholesomeness of dairy products. Because of these concerns and the recognized need of the dairy industry to strictly comply with the FDA requirements regarding allowable tolerance of approved drugs in milk, Hoffmann-La Roche and Rutgers University recently conducted a study to confirm the established milk discard (withdrawal) time following administration of sulfadimethoxine as Albon once-a-day Boluses to lactating dairy cows. The original sulfadimethoxine tolerance of 10 ppb in milk, established after evaluation of extensive human food safety data by the Agency, remains in effect today. The recent study was conducted to determine if changes in dairy management and assay methods implemented since the original milk discard time was established, had changed the drug withdrawal time required to comply with the established tolerance.

description: The mass of the eta_b(1S), measured recently by BABAR, is significantly lower than expected from QCD predictions for the Upsilon(1S) - eta_b(1S) hyperfine splitting. We suggest that the observed eta_b(1S) mass is shifted downwards due to a mixing with a CP-odd Higgs scalar A with a mass m_A in the range 9.4 - 10.5 GeV compatible with LEP, CLEO and BABAR constraints. We determine the resulting predictions for the spectrum of the eta_b(nS) - A system and the branching ratios into tau^+ tau^- as functions of m_A.

description: Gründerzeithäuser haben einen beträchtlichen Anteil am Gebäudebestand von Innenstädten in Mitteleuropa. Die Belüftung von Gründerzeitgebäuden erfolgt typischerweise mittels Fensterlüftung. Im Zuge der Sanierung von Gründerzeitgebäuden stellt sich die Frage hinsichtlich des Einbaus aktiver Lüftungssysteme. Neben klassischen Lüftungsanlagen mit Zu- und Abluft stellen Abluftsysteme mit einer Luftnachströmung mittels Außenbauteil-Luftdurchlässen (z.B. im Bereich von Fenstern) eine Alternative dar. Solche Systeme kommen im Neubau aber auch in der Sanierung immer wieder zur Anwendung. Von Vorteil sind deren einfacher Aufbau und die kostengünstige Umsetzung. Ein wesentlicher Nachteil dieser Systeme ist das Fehlen einer Wärmerückgewinnung. Ein Lösungsansatz ist die Kombination mit einer Abluftwärmepumpe, welche der Fortluft Wärme zum Zweck der Warmwasserbereitung oder Raumheizungsunterstützung entzieht. Dabei ist die energetische bzw. ökonomische Plausibilität dieses Ansatzes zu beurteilen. Im Rahmen dieses Beitrags erfolgt dies anhand der Anwendung in einem Gründerzeitgebäude für die Nutzungsszenarien „Wohnen“ und „Büronutzung“. Mittels Simulationen wird eine energetische Analyse des Systems durchgeführt. Zudem wird untersucht, ob mit diesem Lüftungssystem ein Beitrag zum sommerlichen Wärmeschutz mittels Nachtlüftung erreicht werden kann. Abschließend wird eine statische Amortisationsrechnung durchgeführt. Die Ergebnisse zeigen, dass beim Nutzungsszenario „Wohnen“ durch die Wärmerückgewinnung in den untersuchten Systemvarianten und Betriebsweisen bis zu ca. 40 % des erforderlichen Wärmebedarfs für Warmwasserbereitung und Raumheizung mittels Wärmerückgewinnung aus der Fortluft gedeckt werden kann. Die Amortisationszeit hängt signifikant von der Energiepreissituation ab. Es wird gezeigt, dass statische Amortisationszeiten im Bereich von 7 bis 15 Jahren erreichbar sind. Ein substantieller Beitrag zur Minderung sommerlicher Überwärmung mittels Nachtlüftung konnte in den untersuchten Varianten nicht nachgewiesen werden. Im Fall der „Büronutzung“ ist der Anteil der rückgewonnen Wärme am Gesamtwärmebedarf deutlich geringer, was auf den im Vergleich zur Wohnnutzung niedrigen Warmwasserwärmebedarf zurückzuführen ist. Dadurch ergeben sich lange Amortisationszeiten, welche einen Einsatz dieses Systems bei „Büronutzung“ nicht rechtfertigen.

description: We extend a simple model of a charge trap coupled to a single-electron box to energy ranges and parameters such that it gives new insights and predictions readily observable in many experimental systems. We show that a single background charge is enough to give lines of differential conductance in the stability diagram of the quantum dot, even within undistorted Coulomb diamonds. It also suppresses the current near degeneracy of the impurity charge, and yields negative differential lines far from this degeneracy. We compare this picture to two other accepted explanations for lines in diamonds, based respectively on the excitation spectrum of a quantum dot and on fluctuations of the density-of-states in the contacts. In order to discriminate between these models we emphasize the specific features related to environmental charge traps. Finally we show that our model accounts very well for all the anomalous features observed in silicon nanowire quantum dots.

description: Selenium (Se) in small amounts is essential to animal health (8), but is toxic in larger amounts. Although, Se is a nonessential element for plants, yet its concentration in plants is critical to animal health. Invariably, feeding of selenium rich fodders ends in chronic selenium toxicity in animals. Typical selenium toxicity symptoms in animals and plants were observed in seleniferous regions of Punjab, India (5). Hoof and horn abnormalities in buffaloes, cattle and goats were associated with selenium toxicity (5,6). The present study was, therefore, planned to establish the linkage between the selenium content of soils and fodders and that in blood, hair and hooves of animals. The effect of toxic levels of Se on clinical status and haematological indices was also investigated.

description: Abstract

This study investigates factors contributing to over-indebtedness in 416 agricultural households in Roi-et Province, Thailand, using heteroscedasticity-corrected weighted least squares regression. Key determinants include agricultural assets, health shocks, communication payments, agricultural production input, and natural shocks, all with significant coefficients. Increased agricultural assets, communication payments, and agricultural production input correlate with decreased over-indebtedness, highlighting their mitigating impact. Conversely, higher occurrences of health shocks and natural shocks are linked to increased over-indebtedness. Gender, age, educational level, family size, and farm size exhibit non-significant coefficients. The findings underscore the pivotal roles of agricultural assets, communication payments, and effective risk management in alleviating over-indebtedness, suggesting targeted interventions in these areas for enhancing financial stability in agricultural households.

description: The article analyzes the system of labor law of the Russian Federation in the context of key principles. The purpose of the study is to analyze the system of labor law in the Russian Federation through the prism of key principles. The methodological basis of the study is a general scientific dialectical method of cognition of objective reality. The validity of conclusions is achieved through the integrated application of such a number of methods (historical, comparative-legal, system analysis, synthesis). The concept of “labor law” is concretized, the key principles according to the Labor Code of the Russian Federation are identified. Considerations on the impact of certain principles on the system of labor law in the context of today’s realities are formulated. As a result of the study conclusions are made about the general formalization of labor law and the need for the parties of labor relations to seek a balance of interests.

description: White muscle disease (WMD) in calves is a nutritional degeneration of skeletal and cardiac muscle caused by tocopherol deficiency1, selenium deficiency2 or both3. Author et al. researched WMD in livestock (calves, lambs, foals) in Japan and clarified that the disease is caused by deficiencies of selenium and tocopherol4,5,6). In this study, cases of WMD in calves in Japan were divided into skeletal muscle type with degeneration of skeletal muscle and cardiac muscle type with degeneration of cardiac muscle. We compared the clinico-pathological observations and the levels of tocopherol and selenium.

description: In conditions of environmental radiocontamination, the vegetable-animal products-man food chain becomes particularly critical for the determination of population equivalent doses (1). Such doses may be predicted using contaminant transfer models such as NUCRAC-SAI (2), DOSDIM (3), NRPB (4), PATHWAY (5) and others. These are principally founded on dynamic compartmental systems and they have in common the use of first degree kinetics, which lead to the formulation of a system of differential equations, the solution of which shows the trend of radionuclide concentration in time, in the various environmental and animal matrices. Efficacy verification of these analytical instruments is performed at its best in real situations of radioactive spill in the environment, such as the incident which interested Italy in 1986. In the latter occasion we applied a modulus belonging to a more complex model described below, and which uses the daily dietary intake of 137Cs , to predict the meat and milk contamination variation in time, in the adult bovine. To verify the efficacy of this model we compared calculated values against those measured directly by radiometry of meat and milk samples of the same bovines.

description: We present the design of a Digital Twin for the natural resources of the Loire Valley, one of the most emblematic natural environments in central Europe. A conceptual approach to the data architecture and component integration is shown by describing represented resources, data sources, use cases and functionalities. Such a holistic approach enables easier study, management, understanding and prediction of natural resources and their relationship with human activity.

description: Investigations were carried out in 60 high yielding cattle to improve diagnostic tools in liver disturbances. 10 healthy cows were used to establish reference values, while another group consisted of cows (GML, n= 31) suffering from dislocatio abomasi sinistra with liver affections (elevated AST, GLDH, and bilirubine values) but clinical inapparent after reposition, and the third one (KML, n=19) as GML but clinical disturbed cows. The latter were divided into three units depending on the degree of clinical problems: 1) slight (n=9), 2) medium (n=6), and 3) severe (n=4). In these animals blood was collected and in some cases CSF as well just before the operation and 3 or 4 days later. Herein aminoacids were measured to form the quotient between Valine+Isoleucine+Leucine and Penylalanine+Tyrosine (AA-Index). Ammonia concentrations were estimated too.

Factors contributing to the maintenance and activation of corynebacterial pseudotuberculosis in the laboratory mouse

description: Corynebacterial pseudotuberculosis, a murine disease caused by Corynebacterium kutscheri, occasionally developed in numbers of the departmental strain of random-bred Swiss white mice 3 to 5 weeks following intraperitoneal injection of the Rauscher leukemia virus. Virulent C. kutscheri, extremely difficult to isolate from apparently healthy animals, was frequently cultured from the organs of animals presenting symptoms of the Rauscher disease without active pseudotuberculosis. Representative groups of the departmental strain showed uniformly high resistance to intravenous injection of virulent C. kutscheri in comparison to imported pathogen-free strains, yet succumbed to pseudotuberculosis in large numbers following cortisone treatment; therefore the entire colony was assumed to be latently infected by this organism. Two strains of C. kutscheri were isolated and compared to strains ATCC 15677 and ATCC 15678. The latter strain, a presumed non-pathogenic variant of the former, was compared by cell wall sugar and deoxyribonucleic acid base analysis to the pathogenic strain. It was not possible by these methods to find support for the variant hypothesis. Transfer of the latent state from the departmental strain to a pathogen free strain of mice was attempted by injection of homogenates of visceral organs, but transfer of latency was not successfully demonstrated. The sera of latently infected mice stimulated in vivo phagocytosis of C. kutscheri by mouse peritoneal macrophage, but it was not possible to demonstrate circulating C. kutscheri specific antibody in non-immunized animals. Immunized normal mice of all strains developed high titers of specific circulating antibody following injections of either heat killed C. kutscheri cells or virulent organisms in numbers too low to initiate infection. Circulating antibody was demonstrated by passive bacterial hemagglutination and by indirect fluorescent antibody staining. When immunization was attempted during early Rauscher disease, C. kutscheri antibody production was inhibited. Clearance studies with labeled C. kutscheri showed that the organism is cleared with exceptional rapidity by the reticuloendothelial system of latently infected mice, pathogen free mice and mice with early Rauscher disease. The clearance constant decreased slightly in the above order.

description: The current consensus is that galaxies begin as small density fluctuations in the early Universe and grow by in situ star formation and hierarchical merging. Stars begin to form relatively quickly in sub-galactic sized building blocks called haloes which are subsequently assembled into galaxies. However, exactly when this assembly takes place is a matter of some debate. Here we report that the stellar masses of brightest cluster galaxies, which are the most luminous objects emitting stellar light, some 9 billion years ago are not significantly different from their stellar masses today. Brightest cluster galaxies are almost fully assembled 4-5 Gyrs after the Big Bang, having grown to more than 90% of their final stellar mass by this time. Our data conflict with the most recent galaxy formation models based on the largest simulations of dark matter halo development. These models predict protracted formation of brightest cluster galaxies over a Hubble time, with only 22% of the stellar mass assembled at the epoch probed by our sample. Our findings suggest a new picture in which brightest cluster galaxies experience an early period of rapid growth rather than prolonged hierarchical assembly.

description: We investigate a driven two-channel system where particles on different lanes mutually obstruct each others motion extending an earlier model by Popkov and Peschel [1]. This obstruction may occur in biological contexts due to steric hinderance where motor proteins carry cargos by `walking' on microtubules. Similarly, the model serves as a description for classical spin transport where charged particles with internal states move unidirectionally on a lattice. Three regimes of qualitatively different behavior are identified depending on the strength of coupling between the lanes. For small and large coupling strengths the model can be mapped to a one-channel problem, whereas a new and rich phase behavior emerges for intermediate ones. We derive an approximate but quantitatively accurate theoretical description in terms of a one-site cluster approximation, and obtain insight into the phase behavior through the current-density relations combined with an extremal-current principle. Our results are confirmed by stochastic simulations. [1] V. Popkov and I. Peschel, Phys. Rev. E 64, 026126 (2001).

description: 14 calves of the same breed and age were inoculated with a Pasteurella haemolytica Al (Phal) isolate as described in a previously published protocol. From the onset of the disease, 5 received an antibiotic treatment, 5 others a treatment combining the same antibiotic with a steroidal anti-inflammatory drug while 4 animals did not receive any treatment. A clinical examination was carried out twice a day to determine a mean disease score (MDS). After death or sacrifice the lungs were weighed, the extent of the lesions quantified in a score (mean lung score = MLS) based on combined inspection and palpation. A blood sample was taken each day from each calf with the usual precautions, and the plasma zinc content determined by atomic absorption spectrophotometry. The observations were made over a period of 8 days. 88 zinc determinations were performed. The analysis of variance showed a significant difference (p ≤ 0,01) between the plasma zinc content of calves considered to be clinically normal (MDS < 1,5) and diseased calves (MDS > 1,5), also a significant difference (p ≤ 0,01) between the plasma zinc contents of calves in which MOS < 1,5 + MLS < 1,5 and those in which MDS > 1,5 + MLS > 1,5. The correlation coefficient between terminal zinc levels and lung score (p ≤ 0,01) and between terminal zinc levels and lung weight (p ≤ 0,05) in animals in which the plasma zinc content before death or sacrifice was < 0,96 mg/I, was also significant. These linkages were not apparent in animals with normal plasma zinc levels. In our respiratory disease model these results confirm the linkage between zinc content and the inflammatory reaction brought about by intratracheal inoculation with Phal. They also demonstrate a relationship between hypozincaemia and pulmonary lesions. They therefore have a certain prognosis value. For these different reasons the plasma zinc content could serve as an indicator and provide information about bovine respiratory disease complex evolution.
