    Full Text Available In this study, we examined the relationship between spalling behaviour and spalling ratio of UFC with three kinds of short fibers (jute, polypropylene, water-soluble polyvinyl alcohol at high temperature. The heating temperatures were 400 °C and 600 °C. Although the specimen with jute fiber dosage of 0.19% by volume was occurred explosive spalling, the damage of specimen was slightly small. It appears that the addition of jute fiber to UFC is effective for preventing spalling.

    A novel thermo-mechanical controlled processing (TMCP) schedule involving ultra-fast cooling (UFC) technique was used to process X70 (420 MPa) microalloyed pipeline steel with high strength-high toughness combination. A relative comparison is made between microstructure and mechanical properties between conventionally processed (CP) and ultra-fast cooled (UFC) pipeline steels, together with differences in strengthening mechanisms with respect to both types of processes. UFC-processed steel exhibited best combination of strength and good toughness compared to the CP process. The microstructure of CP pipeline steel mainly consisted of acicular ferrite (AF), bainitic ferrite (BF), and dispersed secondary martensite/austenite (M/A) constituent and a small fraction of fine quasi-polygonal ferrite. In contrast, the microstructure of UFC-processed pipeline steel was predominantly composed of finer AF, BF, and dispersed M/A constituent. The primary strengthening mechanisms in UFC pipeline steel were grain size strengthening and dislocation strengthening with strength increment of ~277 and ~151 MPa, respectively. However, the strengthening contribution in CP steel was related to grain size strengthening, dislocation strengthening, and precipitation strengthening, and the corresponding strength increments were ~212, ~149 and ~86 MPa, respectively. The decrease in strength induced by reducing Nb and Cr in UFC pipeline steel was compensated by enhancing the contribution of grain size strengthening in the UFC process. In conclusion, cooling schedule of UFC combined with LC is a promising method for processing low-cost pipeline steels.

    Based on medium plate runout table ultra-fast cooling ( UFC)-accelerated cooling equipment ( ACC) system, a heat transfer coefficient model was constructed. Firstly, according to the measured data, heat transfer coefficients under different roll speed and water volume were calculated by using an inverse heat conduction method. Secondly, a monofactorial heat transfer coefficient calculation formula was obtained. Finally, the heat transfer coefficient model based on medium plate runout table UFC-ACC system was constructed by intercept function, slope function, interaction influence function and linear or nonlinear influencing factors. The precision of these models was validated by comparing model prediction value with measured data, and the results were in good agreement with practical needs, and the average deviation was less than 5%.

    Full Text Available Analisar os determinantes dos desempenhos de candidatos ao concurso vestibular da UFC constitui-se o foco central deste artigo. A metodologia baseou-se em uma função de produção de rendimento educacional e estimação feita por modelos econométricos de escolha discreta, dicotômico e policotômico, com o fito de se extrair as chances de os candidatos lograrem êxito em todas as áreas do concurso. Para tanto, foi utilizada uma base de dados derivada de questionários socioeconômicos dos candidatos, e disponibilizados pela Pró-Reitoria de Graduação da UFC. Dos resultados estatisticamente robustos, constatou-se no vetor de variáveis socioeconômicas um forte efeito negativo na chance de sucesso no vestibular para aqueles candidatos que se encontram no mercado de trabalho. Background familiar foi incisivo sobre os sucessos dos candidatos, vez que aqueles que possuem pais com nível superior demonstram possuir melhor performance no exame. A qualidade do ensino público de nível médio transpareceu nos resultados ao reduzir sobremaneira as chances de êxito para os candidatos advindos de escolas públicas. Analisando-se os desempenhos por área, concluiu-se, dentro de cenários de previsão, que candidatos com elevada chance de sucesso em determinada área não a manteria em outras áreas. Descartou-se o efeito concorrência como determinante do desempenho em cada área.

    The Air Logistics Command within the Air Force is responsible for maintaining a wide variety of aircraft fleets and weapon systems. To maintain these fleets and systems requires specialized test equipment that provides data concerning the behavior of a particular device. The test equipment is used to 'poke and prod' the device to determine its functionality. The data represent voltages, pressures, torques, temperatures, etc. and are called testpoints. These testpoints can be defined numerically as being in or out of limits/tolerance. Some test equipment is termed 'automatic' because it is computer-controlled. Due to the fact that effective maintenance in the test arena requires a significant amount of expertise, it is an ideal area for the application of knowledge-based system technology. Such a system would take testpoint data, identify values out-of-limits, and determine potential underlying problems based on what is out-of-limits and how far. This paper discusses the application of this technology to a device called the Unified Fuel Control (UFC) which is maintained in this manner.

  14. Infilled masonry walls contribution in mitigating progressive collapse of multistory reinforced concrete structures according to UFC guidelines

    A structure is subjected to progressive collapse when an element fails, resulting in failure of adjoining structural elements which, in their turn, cause further structural failure leading eventually to partial or total collapse. The failure of a primary vertical support might occur due to extreme loadings such as bomb explosion in a terrorist attack, gas explosion and huge impact of a car in the parking area. Different guidelines such as the General Services Administration (GSA 2003) and the Unified Facilities Criteria (UFC 2009) addressed the structural progressive collapse due to the sudden loss of a main vertical support. In the current study, a progressive collapse assessment according to the UFC guidelines is carried out for a typical ten-story reinforced concrete framed structure designed according to codes [(ACI 318-08) and (ASCE 7-10)] for minimum design loads for buildings and other structures. Fully nonlinear dynamic analysis for the structure was carried out using Applied Element Method (AEM). The investigated cases included the removal of a corner column, an edge column, an edge shear wall, internal columns and internal shear wall. The numerical analysis showed that simplification of the problem into 3D bare frames would lead to uneconomical design. It was found for the studied case that, the infilled masonry walls have a valuable contribution in mitigating progressive collapse of the reinforced concrete framed structures. Neglecting these walls would lead to uneconomical design.

  15. What if? The farther shores of neuroethics: commentary on "Neuroscience may supersede ethics and law".

    Science.gov (United States)

    Greely, Henry T

    2012-09-01

    Neuroscience is clearly making enormous progress toward understanding how human brains work. The implications of this progress for ethics, law, society, and culture are much less clear. Some have argued that neuroscience will lead to vast changes, superseding much of law and ethics. The likely limits to the explanatory power of neuroscience argue against that position, as do the limits to the social relevance of what neuroscience will be able to explain. At the same time neuroscience is likely to change societies through increasing their abilities to predict future behavior, to infer subjective mental states by observing physical brain states ("read minds"), to provide evidence in some cases relevant to criminal responsibility, to provide new ways to intervene to "treat antisocial brains," and to enhance healthy brains. Neuroscience should make important cultural changes in our special, and specially negative, views of "mental" versus "physical" illness by showing that mental illness is a dysfunction of a physical organ. It will not likely change our beliefs, implicit or explicit, in free will, or spark a new conflict between science and religion akin to the creationism controversy.

  16. Manipulating or superseding host recombination functions: a dilemma that shapes phage evolvability.

    Phages, like many parasites, tend to have small genomes and may encode autonomous functions or manipulate those of their hosts'. Recombination functions are essential for phage replication and diversification. They are also nearly ubiquitous in bacteria. The E. coli genome encodes many copies of an octamer (Chi) motif that upon recognition by RecBCD favors repair of double strand breaks by homologous recombination. This might allow self from non-self discrimination because RecBCD degrades DNA lacking Chi. Bacteriophage Lambda, an E. coli parasite, lacks Chi motifs, but escapes degradation by inhibiting RecBCD and encoding its own autonomous recombination machinery. We found that only half of 275 lambdoid genomes encode recombinases, the remaining relying on the host's machinery. Unexpectedly, we found that some lambdoid phages contain extremely high numbers of Chi motifs concentrated between the phage origin of replication and the packaging site. This suggests a tight association between replication, packaging and RecBCD-mediated recombination in these phages. Indeed, phages lacking recombinases strongly over-represent Chi motifs. Conversely, phages encoding recombinases and inhibiting host recombination machinery select for the absence of Chi motifs. Host and phage recombinases use different mechanisms and the latter are more tolerant to sequence divergence. Accordingly, we show that phages encoding their own recombination machinery have more mosaic genomes resulting from recent recombination events and have more diverse gene repertoires, i.e. larger pan genomes. We discuss the costs and benefits of superseding or manipulating host recombination functions and how this decision shapes phage genome structure and evolvability.

    New scintillators for high-resolution gamma ray spectroscopy have been identified, grown and characterized. Our development efforts have focused on two classes of high light yield materials: Europium-doped alkaline earth halides and Cerium-doped garnets. Of the halide single crystals we have grown by the Bridgman method - SrI{sub 2}, CaI{sub 2}, SrBr{sub 2}, BaI{sub 2} and BaBr{sub 2} - SrI{sub 2} is the most promising. SrI{sub 2}(Eu) emits into the Eu{sup 2+} band, centered at 435 nm, with a decay time of 1.2 {micro}s and a light yield of up to 115,000 photons/MeV. It offers energy resolution better than 3% FWHM at 662 keV, and exhibits excellent light yield proportionality. Transparent ceramics fabrication allows production of Gadolinium- and Terbium-based garnets which are not growable by melt techniques due to phase instabilities. While scintillation light yields of Cerium-doped ceramic garnets are high, light yield non-proportionality and slow decay components appear to limit their prospects for high energy resolution. We are developing an understanding of the mechanisms underlying energy dependent scintillation light yield non-proportionality and how it affects energy resolution. We have also identified aspects of optical design that can be optimized to enhance energy resolution.

    Removing anchored spirals from obstacles is an important step in terminating cardiac arrhythmia. Conventional anti-tachycardia pacing (ATP) has this ability, but only under very restrictive conditions. In a generic model of excitable media, we demonstrate that for unpinning spiral waves from obstacles this profound limitation of ATP can be overcome by far field pacing (FFP). More specifically, an argument is presented for why FFP includes and thus can only extend the capabilities of ATP in the configurations considered. By numerical simulations, we show that in the model there exists a parameter region in which unpinning is possible by FFP but not by ATP. The relevance of this result regarding clinical applications is discussed.

    Reference values are generally used to allow a decision on whether a laboratory value is in the normal range or if it mirrors a pathological process. This decision is especially difficult to take, when the pathological process is just starting and the values are relatively close to the normal range. Particularly in this phase, the decision is extremely important. Harris and later on Fraser have realized that there are two variables that contribute to the credibility and significance of a measured analyte. 1. The imprecision of the measurement itself. These values have become relatively low in recent years: they amount to values between 1 and 5 %. 2. The within person biological variability, which can be 100 % or more. Both variables combined yield the "reference change value" (RCV) to define the minimal significant difference between two measurements at different time points. When using this concept, differences between two measurements can be detected before the normal range is exceeded. For any given patient the reference values of a population is actually not of primary concern. It is important to know that his personal data exceed his personal normal range, which is dependent on RCV. For many analytes in clinical chemistry and hematology the use of RCV rather than the normal range as reference improves the decision making process in a clinical setting.

    Diversification of agriculture was one of the strengthened aims of the greening payment of European Agricultural Policy (CAP) as diversification provides numerous ecosystems services compared to cereal-intensive crop rotations. This study focuses on current minor crops in Finland that have potential for expanded production and considers changes in their cropping areas, yield trends, breeding gains, roles in crop rotations and potential for improving resilience. Long-term datasets of Natural Resources Institute Finland and farmers' land use data from the Agency of Rural Affairs were used to analyze the above-mentioned trends and changes. The role of minor crops in rotations declined when early and late CAP periods were compared and that of cereal monocultures strengthened. Genetic yield potentials of minor crops have increased as also genetic improvements in quality traits, although some typical trade-offs with improved yields have also appeared. However, the gap between potential and attained yields has expanded, depending on the minor crop, as national yield trends have either stagnated or declined. When comparing genetic improvements of minor crops to those of the emerging major crop, spring wheat, breeding achievements in minor crops were lower. It was evident that the current agricultural policies in the prevailing market and the price environment have not encouraged cultivation of minor crops but further strengthened the role of cereal monocultures. We suggest optimization of agricultural land use, which is a core element of sustainable intensification, as a future means to couple long-term environmental sustainability with better success in economic profitability and social acceptability. This calls for development of effective policy instruments to support farmer's diversification actions.

    Nanotechnology and, specifically, nanomedicine has been touted as the next breakthrough technology for medical sciences. Although there are large advances being seen in the preclinical phases of development, there is still a paucity of viable and effective nanomedicine technologies in the clinical setting. We attempt to provide some suggestions as to the stumbling blocks of meaningful translation of this technology from the bench to the bedside. We give due consideration to the role of evidence-based medicine, regulatory pathways, and the commercialization efforts of nanomedicine at various stages in playing key roles in moving this technology into clinical use.

  16. Dose Titration Algorithm Tuning (DTAT) should supersede 'the' Maximum Tolerated Dose (MTD) in oncology dose-finding trials.

    Background. Absent adaptive, individualized dose-finding in early-phase oncology trials, subsequent 'confirmatory' Phase III trials risk suboptimal dosing, with resulting loss of statistical power and reduced probability of technical success for the investigational therapy. While progress has been made toward explicitly adaptive dose-finding and quantitative modeling of dose-response relationships, most such work continues to be organized around a concept of 'the' maximum tolerated dose (MTD). The purpose of this paper is to demonstrate concretely how the aim of early-phase trials might be conceived, not as 'dose-finding', but as dose titration algorithm (DTA)-finding. Methods. A Phase I dosing study is simulated, for a notional cytotoxic chemotherapy drug, with neutropenia constituting the critical dose-limiting toxicity. The drug's population pharmacokinetics and myelosuppression dynamics are simulated using published parameter estimates for docetaxel. The amenability of this model to linearization is explored empirically. The properties of a simple DTA targeting neutrophil nadir of 500 cells/mm (3) using a Newton-Raphson heuristic are explored through simulation in 25 simulated study subjects. Results. Individual-level myelosuppression dynamics in the simulation model approximately linearize under simple transformations of neutrophil concentration and drug dose. The simulated dose titration exhibits largely satisfactory convergence, with great variance in individualized optimal dosing. Some titration courses exhibit overshooting. Conclusions. The large inter-individual variability in simulated optimal dosing underscores the need to replace 'the' MTD with an individualized concept of MTD i . To illustrate this principle, the simplest possible DTA capable of realizing such a concept is demonstrated. Qualitative phenomena observed in this demonstration support discussion of the notion of tuning such algorithms. Although here illustrated specifically in relation to cytotoxic chemotherapy, the DTAT principle appears similarly applicable to Phase I studies of cancer immunotherapy and molecularly targeted agents.

    The growth performance of weanling albino rats (Rattus norvegicus) maintained on different accessions (offspring of a variety that was planted/collected at a specific location and time but differing in certain morphologic characteristics) of cooked Colocasia esculenta (cocoyam)-based diets (UFCe1-UFCe7) for 28 days was investigated. Proximate analysis of the formulated diets revealed that UFCe3, UFCe4, UFCe5, UFCe6, and UFCe7 had significantly (Pesculenta had higher ash contents. Similarly, all the accessions of the C. esculenta-based diet had lower crude lipid content, whereas UFCe3-UFCe7 had significantly lower protein content. Although the crude fiber content was significantly higher in UFCe2, UFCe4, and UFCe5, only UFCe3 had significantly higher carbohydrate content among all the accessions of C. esculenta-based diets. UFCe1, UFCe2, UFCe4, UFCe5, and UFCe6 increased the average weekly water intake, feed consumption, total body weight, liver-body weight ratio, and kidney-body weight ratio of the animals; UFCe3 and UFCe7 decreased these measures. Overall, UFCe1, UFCe2, UFCe4, UFCe5, and UFCe6 are recommended as diets with promise to enhance growth performance in the animals.

    For many decorative applications like industrial and architectural paints, prevention of metal substrates from corrosion is a primary function of organic coatings. Triggered release of inhibitor species is generally accepted as a remedy for starting corrosion in case of coatings damage. A polyurethane based coating, doped with bola-amphiphiles of varying molecular weight but with a common head group motif that stems from ring-opened alkenyl succinic anhydride, enables passivation of the defect and mitigates cathodic delamination, if applied on cold rolled steel. An antagonistic effect results from the intercalation of the bola-amphiphiles into layered double hydroxide Zn2Al(OH)6 and subsequent incorporation of the hybrid phase into the organic matrix. In particular higher molecular weight bola-amphiphiles get immobilized through alkaline degradation of the layered framework in the basic milieu at the cathode. By means of sediments from colloidal states it is demonstrated that in-situ formed zinc oxide encapsulates the hybrid phase, evidenced by impeded dissolution of the ZnO based shell into caustic soda. While inhibition of steel corrosion results from a Donnan barrier layer, impeded zinc oxide dissolution is rooted in zinc catalyzed bola-amphiphile hydrolysis and layered deposition of the crystalline spacer diol hydrogenated bisphenol-A.

    The liver and kidney functional indices of weanling albino rats (Rattus norvegicus) maintained on different accessions (offspring of a variety planted/collected at a specific location and time but differing in certain morphological characteristics) of cooked Colocasia esculenta (cocoyam)-based diets (UFCe1-UFCe7) for 28 days were investigated. All the accessions of C. esculenta-based diets did not significantly (P > .05) alter the serum levels of albumin, globulin, inorganic phosphorus, calcium, magnesium, and uric acid of the animals.The total protein and total bilirubin levels decreased only in the UFCe3- and UFCe4-fed animals, respectively. Whereas UFCe1 and UFCe2 significantly decreased the conjugated bilirubin levels, UFCe3 and UFCe6 increased it. While all the accessions of C. esculenta-based diet decreased the serum alkaline phosphatase activity, γ-glutamyl transferase activity was increased. UFCe1 and UFCe5 increased the serum alanine aminotransferase activity, whereas UFCe4 decreased the activity of the enzyme. Again, UFCe3 and UFCe1 increased the serum creatinine and aspartate aminotransferase activity of the animals. Furthermore, the computed blood urea nitrogen:creatinine ratio was higher in animals maintained on UFCe1-, UFCe3-, UFCe4-, and UFCe5-based diets. Whereas UFCe6 and UFCe7 increased the level of sodium in the serum of the animals, UFCe4 and UFCe5 decreased the chloride level. The serum urea level was decreased by UFCe1, UFCe3, UFCe4, and UFCe5, whereas the potassium level increased in the UFCe4-, UFCe6-, and UFCe7-fed animals. Overall, the results revealed that all the accessions of C. esculenta produced selective effects on the hepatic and renal functional indices of the weanling rats. The highest alterations were produced by UFCe4, whereas the least was from UFCe2. These alterations may have consequential effects on the normal functioning of the liver and kidney of the animals. UFCe2 exhibited the least toxicity risk among the

    This article reports a study on the structural characterization and evaluation of thermal degradation kinetics of urea–formaldehyde resin modified with cellulose, known as UFC resin. Structural characterization of UFC undertaken by scanning electron microscopy, Fourier transform infrared and X-ray diffractionanalyses reveals that the resin is fairly homogenous, and it constitutes of partly crystalline structure including urea–formaldehyde/cellulose interface morphology different from UFC precursors. Measurement of inherent thermal stability, probing reaction complexity and the thermal degradation kinetic analysis of UFC have been carried out by thermogravimetric/differential thermal analyses (TGA/DTA) under non-isothermal conditions. The integral proceduredecomposition temperature elucidates significant thermal stability of UFC. TGA/DTA analyses suggest highly complicated reaction profile for thermal degradation of UFC, comprising various parallel/consecutive reactions.Different differential and integral isoconversional methods have been employed to determine the thermal degradation activation energy of UFC. Substantial variation in activation energy with the advancement of reaction verifiesmulti-step reaction pathway of UFC. A plausible interpretation of the obtained kinetic parameters of UFC thermal degradation with regard to their physical meanings is given and discussed in this study.

    At the heart of any finite element simulation is the assembly of matrices and vectors from discrete variational forms. We propose a general interface between problem-specific and general-purpose components of finite element programs. This interface is called Unified Form-assembly Code (UFC). A wide range of finite element problems is covered, including mixed finite elements and discontinuous Galerkin methods. We discuss how the UFC interface enables implementations of variational form evaluation to be independent of mesh and linear algebra components. UFC does not depend on any external libraries, and is released into the public domain.

    Colocasia esculenta (L.) Schott (cocoyam) is cultivated mainly for its edible tubers. The effect of cooking the tubers on the proximate composition of seven accessions (UFCe1-UFCe7) of the crop growing in South Africa was investigated. When compared with the uncooked, the ash and crude fibre contents of the accessions significantly decreased after cooking. The moisture content, crude protein, crude lipid, carbohydrate and caloric contents increased with cooking in all the accessions, except UFCe1 and UFCe5 where the crude lipid content reduced. The results indicate that cooking enhanced the carbohydrate, energy and protein contents of the tubers. They further showed that the tubers could be used for allergic infants, old people and invalids since the fibre contents were still appreciably high despite the slight reduction after cooking the tubers.

    Bentonite is a naturally occurring clay-rich sediment containing montmorillonite, a smectitic clay mineral that has a high cation exchange capacity and swells upon contact with water. Owing to these characteristics, highly compacted bentonite (HCB) is an often included component of engineered barrier systems (EBS) designed to protect used fuel containers (UFCs) in deep geological repositories (DGR) for high-level nuclear waste. The low water activity and high swelling pressure of HCB suppresses microbial activity and the related production of sulphide that could cause microbiologically influenced corrosion (MIC) of UFCs The Canadian Nuclear Waste Management Organization (NWMO) has chosen a UFC that consists of an inner steel core and outer copper coating which is resistant to corrosion. However, under anaerobic conditions, MIC can still contribute to UFC corrosion if sulphides are present in the groundwater. Therefore the EBS consisting of bentonite blocks and pellets has been designed to impede the movement of sulphides to the UFC. In order to examine the effectiveness of the EBS, a 3D numerical model was developed capable of simulating the diffusive transport of sulphide within the NWMO EBS. The model was developed using COMSOL Multiphysics, a finite element software package and is parametric which allows the impact of different repository layouts to be assessed. The developed model was of the entire NWMO placement room, as well as, a stand-alone UFC and included conservative assumptions such as a fully saturated system and a constant concentration boundary condition. The results showed that the highest sulphide flux occurred at the semi-spherical end caps of the UFC. Further studies examined the effect of sulphide hotspots and fractures, representing possible EBS failure mechanisms. The model results highlight that even with conservative assumptions the chosen EBS will effectively protect the UFC from microbiologically influenced corrosion.

    Objectives To study the relation between night urinary free cortisol (UFC) ex-cretion and hypertension in youth. Methods Nighturinary free cortisol excretion and blood pressure & itsrelated factor were measured in 188 young people.Results In young men with hypertension the 8 h'snight UFC excretion was significantly higher than thatin the group with normal blood pressure 21.57 ± 6.28μg/8hvs 10. 54 ± 5. 46μg/8 h (P <0.05). Inagroup of young people with positive family history ofhypertension, the night UFC excretion was much higherthan that in the group with negative family history ofhypertension. Men excrete much more night UFC thanwomen (12.73±5.85 μg/8hvs7.80±4.15 μg/8h, P < 0. 05). Conclusions There is an associationbetween hypertension and high 8h's night UFC excre-tion; furthermore, there is gender difference in nightUFC excretion.

It was observed that the absence of B. cereus, coliforms, filamentous fungus and leavenings. The evaluation of the irradiation of the black pepper inoculated with 10{sup 6} UFC/g of B. cereus spores of with doses of gamma radiation varying between 2 and 10 kGy evidenced that doses up to 5 kGy had been enough to reduce the counting of, approximately, 10{sup 6} UFC/g of aerobic mesofilis organisms and 10{sup 4} UFC/g of B. cereus spores the not detectable numbers by the used methodology. The dose of reduction decimal (D{sub 10}) for the inoculated B. cereus spores in black pepper was of 1,78 kGy.

  14. Association between sleep duration and 24-hour urine free cortisol in the MrOS Sleep Study.

    Directory of Open Access Journals (Sweden)

    Madhu N Rao

    Full Text Available CONTEXT: Short sleep duration is associated with adverse health outcomes, but the mechanisms involved are unknown. It has been postulated that short sleep duration may elevate cortisol levels, but studies have had conflicting results. It is unclear whether these differing findings may be due to methodological issues, such as assessment of sleep duration. Specifically, objective versus subjective methods of measuring habitual sleep duration may account for the conflicting results found in epidemiological studies. OBJECTIVE: Our goal was to determine whether habitual sleep duration, measured objectively (by actigraphy and subjectively (by self-report, was associated with 24-hour urine free cortisol (UFC, a measure of integrated cortisol secretion. Our secondary goal was to determine whether slow wave sleep (SWS, determined by polysomnography was associated with 24-hour UFC. DESIGN/SETTING: Cross sectional study of community dwelling older men. PATIENTS/PARTICIPANTS: 325 men (mean age = 76.6 years, SD = 5.5 from the Portland site of the MrOS Sleep Study, who underwent 24-hour urine collection, polysomnography, actigraphy and sleep questionnaire. PRIMARY OUTCOME: 24-hour UFC. RESULTS: In this study of community dwelling older men, self-reported sleep duration was inversely related to 24-hour UFC levels. Participants reporting 5 to 8 hours of habitual sleep. However, sleep duration determined by actigraphy was not associated with 24-hour UFC in either univariable or multivariable regression models. SWS was not associated with 24-hour UFC. CONCLUSION: Objectively measured (i.e., actigraphic sleep duration is not associated with 24-hour UFC in these community dwelling older men. This finding, together with prior studies, suggests that elevated levels of integrated cortisol secretion is not the mechanisms by which short sleep duration leads to adverse health outcomes.

    2017-07-01

    A novel process comprised of ultra-fast cooling after control rolling, intercritical quenching and tempering (UFC-LT) was applied to 3.5%Ni steel. In addition, quenching and tempering (QT) treatment was conducted in comparison. The present study focuses on the relationship between the microstructure and cryogenic toughness of 3.5%Ni steel. Results show that the microstructure of steel treated by UFC-LT consisted of tempered martensite, intercritical ferrite and two types of reversed austenite (RA) (needle shape and blocky). Compared to the QT sample, the UFC-LT sample's ultimate tensile strength decreased slightly, while its elongation increased from 32.3 to 35.7%, and its Charpy absorption energy at -135 °C increased from 112 to 237 J. The ductile-brittle transition temperature of UFC-LT sample was lower than that of the QT sample by 18 °C. The superior cryogenic toughness after UFC-LT compared to QT treatment can be attributed to the dissolution of cementite, approximately 3.0% increase in RA and the decrease in effective grain size.

    Full Text Available Jennet milk as human food is hypoallergenic for patients affected by Cow Milk Protein Allergy and multiple food allergies. For these pathologies, jennet milk represents the best alternative to other types of milk. Therefore, jennet milk consumers are very sensible to the effects of pathogens' contaminations, and several hygienic practices during the milk production need to be adopted. During regular monitoring in one Sicilian jennet farm, Bacillus cereus in the milk was detected. In 3 bulk milk samples (maximum concentration: 1.2 x 103 ufc/ml, in 3 individual milk samples (10, 20 e 60 ufc/ml, in the milk filter (5 ufc/cm2, in the soil (maximum concentration: 1.5 x 103 ufc/g, on the hands and the gloves of two milkers, on the animal hide (from 1 to 3 ufc/cm2. No spores were detected. A total of 8 Bacillus cereus s.s. strains were analyzed for diarrhoic toxin, and 6 strains producing enterotoxins resulted. The improvement of environmental and milking hygienic conditions reduced Bacillus cereus concentration.

    Microstructure can vary significantly through thickness after ultrafast cooling of rolled steel plates, impacting their mechanical properties. This study examined the microstructure, microstructural banding at centerline, and mechanical properties through thickness for different ultrafast cooling conditions and rolling temperatures. One set of steels (UC1 and UC2) were ultrafast-cooled (UFC) at 40 K/s after finish rolling at 1223 K and 1193 K (950 °C and 910 °C), respectively, while the second set (LC) was cooled by laminar cooling at 17 K/s after finish rolling at 1238 K (965 °C). UFC produced microstructural variation through thickness; highly dislocated lath-type bainitic ferrite was formed near the surface, whereas the primary microstructure was acicular ferrite and irregular polygonal ferrite in the interior of UC1 and UC2 steels, respectively. However, UFC has the advantage of suppression of microstructural banding in centerline segregation regions. The ferrite grain size in both UFC-cooled steels was refined to ~5 μm, increasing strength and toughness. The optimum combination of properties was obtained in UC2 steel with appropriate low finish rolling temperature, being attributed to the distinct microstructure resulting from work-hardened austenite before UFC.

    Full Text Available Foram analisadas 96 amostras de carne-de-sol, das quais 48 foram coletadas em estabelecimentos inspecionados e 48 em estabelecimentos não-inspecionados. Com o objetivo de avaliar as condições higiênico-sanitárias desse produto, durante o processamento e a comercialização, pesquisou-se a incidência de bactérias mesófilas, bolores e leveduras, Staphylococcus aureus, coliformes fecais e Escherichia coli. Foram analisados ainda, alguns parâmetros físico-químicos como atividade de água e teor de cloreto de sódio. Nos dois grupos os resultados obtidos nas análises microbiológicas foram bastante elevados. Nas amostras provenientes de estabelecimentos inspecionados as médias da contagem total de bactérias mesófilas, bolores e leveduras, Staphylococcus spp e coliformes fecais foram 6,2Log UFC/g, 3,8Log UFC/g, 7,4Log UFC/g e 1,3Log NMP/g, respectivamente, e, nas comercializadas sem inspeção foram 7,4Log UFC/g, 4,4Log UFC/g, 6,8Log UFC/g e 2,6Log NMP/g, respectivamente. Esses resultados sugerem que houve falhas tanto no processamento como na manipulação desses produtos, sendo que a contaminação fecal foi bem mais elevada nas amostras coletadas nos estabelecimentos sem inspeção. A variação dos teores de cloreto de sódio e atividade de água das amostras indicou falta de padronização de qualidade da carne-de-sol, havendo a necessidade de se estabelecer parâmetros legais tanto microbiológicos como físico-químicos, capazes de oferecer ao consumidor um alimento seguro.A total of 96 samples of sun meat were analyzed, 48 of them were collected in inspected establishments and the other 48 in establishments without inspection.

    To compare the sensitivity and specificity between the 24 hour urine free cortisol (24 h UFC) and serum cortisol in dexamethasone suppression test (DST) in the diagnosis of Cushing syndrome (CS). Combined low dose DST (LDDST) and high dose DST (HDDST) were carried out in 67 cases of CS with surgically confirmed cases in recent 3 years(from January 2011 to November 2015). The serum cortisol and 24 h UFC were collected simultaneously for each subject and the sensitivity and specificity of serum cortisol and 24 h UFC were compared. There were Cushing disease (CD) group (n=53), ectopic adrenocorticotropic hormone (ACTH) syndrome group (n=7) and ACTH-independent Cushing syndrome group (n=7) according to the etiology of hypercorticordism.There were no significant differences among 3 groups in gender and age.The sensitivity of serum cortisol of different cut off points(50, 110, 140 nmol/L and 50% of control)after LDDST was 97.01%, 86.57%, 83.58% and 70.15% respectively.Meanwhile, the sensitivity of cutoff point of 24 h UFC Cushing syndrome.There was no significant differences in two groups between serum cortisol Cushing disease was 60.38% and 90.57%, and the specificity was 91.43% and 96.00% respectively.There were significant differences between serum cortisol and 24 h UFC in both of sensitivity and specificity (both P<0.05). In addition, if the suppression rate of 24 h UFC in HDDST was adjusted to 60.85% according to receiver operating characteristic (ROC) curve, it could have the best levels of sensitivity (92.6%) with the specificity of 85.7%. If the suppression rate of serum cortisol was adjusted to 61.53% in HDDST according to ROC curve, it could have the best sensitivity (64.8%) with the specificity of 78.6% accordingly. In combined LDDST, the serum cortisol <50 nmol/L had a higher sensitivity than the 24 h UFC<32 nmol when they were used as the criteria in determining the diagnosis of CS.In HDDST, the sensitivity and specificity of suppression rate of 24 h UFC

    Paramonov, Yu.; Cimanis, V.; Varickis, S.; Kleinhofs, M.

    2013-11-01

    A review of the previous works of the authors dedicated to the use of Daniels' sequence (DS) for analyzing the relation between the distribution of the static strength of components of a unidirectional fibrous composite (UFC) and the distribution of its fatigue life is presented. A generalization of the DS which can be used to analyze the association of distribution of the static strength of composite components with distribution of the static strength of the UFC itself is given. In analyzing the fatigue life of a UFC, unlike in Daniels' model, the loading rate and randomness of the number of still workable components in the weak microvolume in which the destruction process takes place are taken into account. By analyzing the fatigue life, it is possible to explain the existence of the random fatigue strength and to calculate the maximum load at which the probability of absence of fatigue failure is great enough when the number of cycles of fatigue loading tends to infinity. Numerical examples of processing of experimental data are presented, and estimates for parameters of the corresponding nonlinear regression model, which can be interpreted as the strength parameters of UFC, are obtained.

    Temperature deviation between surface and the center of hot rolled strip is formed during ultra-fast cooling (UFC). Surface temperature would rise when temperature deviation goes up to an extent, and strip re-reddening phenomenon will appear. Strip re-reddening affects the stability of strip microstructure, property and temperature control precision. Thus, it is necessary to conduct research on re-reddening temperature changing law to improve strip property and temperature control precision. Strip temperature trends for various strip thicknesses and ultra-fast cooling rates were obtained by numerical calculation method. Re-reddening temperature, temperature deviation between surface and center, and boundary layer position changing law were obtained. By comparison, some conclusions were obtained: UFC re-reddening temperature and laminar cooling (LC) re-reddening temperature were linear to ultra-fast cooling rate respectively. Ultra-fast cooling rate affected UFC re-reddening temperature greatly, but it had little effect on LC re-reddening temperature. Equations which were used to calculate UFC re-reddening temperature, LC re-reddening temperature and maximum temperature deviation were obtained. The position of boundary layer stayed in 1/4 strip thickness.

    The controlled cooling technology following hot rolling process is a vital factor that affects the final micro- structure and mechanical properties of the hot-rolled transformation induced plasticity (TRIP) steels. In the present study, low alloy C-Si-Mn TRIP steel was successfully fabricated by hot rolling process with a 4450 hot roiling mill. To maximize the volume fraction and stability of retained austenite of the steel, two different cooling methods (aircooling and ultra-fast cooling "AC-UFC" and ultrmfast cooling, air cooling and ultra-fast cooling "UFC-AC-UFC") were conducted. The effects of the cooling method on the microstructure of hot-rolled TRIP steel were investigated via optical microscope, transmission electron microscope and conversion electron Mossbauer spectroscope. The mechanical properties of the steel were also evaluated by conventional tensile test. The results indicated that ferrite and bainite in the microstructure were refined with the cooling method of UFC-AC-UFC. The morphology of retained austenite was also changed from small islands distributing in bainite district (obtained with AC-UFC) to granular shape locating at the triple junction of the ferrite grain boundaries (obtained with UFC-AC-UFC). As a result, the TRIP steel with a content of retained austenite of 11. 52%, total elongation of 32% and product of tensile strength and total elongation of 27 552 MPa·% was obtained.

    Pulp (CP) and ultrafiltered (UF) cactus pear extracts were encapsulated with Capsul (C) by applying a central composite design (CP-C and UF-C systems) by spray-drying. To evaluate the effect of the extract, microparticles obtained under optimal conditions were characterised and stored at 60 °C. Betacyanin and betaxanthin encapsulation efficiency reached values above 98% for both systems studied. This efficiency was attributed to strong interactions between betalains and the polymer. Betalain degradation in CP-C and UF-C microparticles followed pseudo-first order kinetics. The betacyanin degradation rate constant was significantly higher for CP-C than for UF-C. These results suggested that the mucilage or higher sugar content of CP increased the hygroscopicity of the CP-C microparticles, leading to the degradation of betalain. The hydrolysis pathway was the main mechanism of betanin degradation during microparticle storage. These results demonstrate the potential utility of both CP-C and UF-C microparticles as natural colourants for healthy foods.

    Full Text Available Campylobacter spp. are bacterial pathogens associated with human gastroenteritis worldwide. In Europe, campylobacteriosis is one of the leading food-borne bacterial diseases and the consumption of poultry meats is suspected to be one of the major causes of illness. The aim of our research was to determine the number of Campylobacter spp. in poultry carcasses and in poultry meat samples during their storage till to retail markets. The study was conducted from February 2009 to February 2010 at slaughterhouse in Veneto region, followed by a test of fresh poultry meat placed on the market for sale. A total of 90 poultry carcass and 90 samples of poultry meat were examined. The quantitative examination resulted in Campylobacter spp. counts (mean: for carcasses between 2,0 ∙101 ufc/g and 1,5 ∙103 ufc/g (4,2 ∙102 and poultry meat between 2,0 ∙101 ufc/g and 3,7 ∙102 ufc/g (8,1 ∙101. The majority of isolates were classified as Campylobacter jejuni (58,3%, Campylobacter coli (22,9% or Arcobacter cryaerophilus (4,2%.

    The effects of vacuum packaging followed by gamma irradiation treatment (1.5 kGy) on the shelf-life of fillets of chub mackerel (Scomber japonicus) were examined, during chill storage. The control and the treated packs were analyzed periodically for chemical (TMA, TBARS, biogenic amines) and microbial characteristics. Based on chemical and microbial data, vacuum packaging - by itself - was improper in extending the shelf-life of chub mackerel, estimated to 7 days. On the 7th day, TMA and Histamine contents reached the defect action levels, associated with the presence of mesophiles (3.7 log UFC/g); total coliforms (3.5 log UFC/g); staphylococci (1.9 log UFC/g) and the emergence of Pseudomonas (1.7 log UFC/g), in both the control and the vacuum packaged lots. Combination of vacuum packaging and gamma-irradiation was found to delay the spoilage during 14 days of refrigerated storage, based on chemical and microbial analyses. Similarly, consumer hedonic tests were performed to determine the effect of different treatments on the taste of fish fillets. For all treatments, consumers failed to discriminate treated samples from the control, on the 2nd day of storage (p > 0.05). The acceptability test showed that low-dose irradiation (1.5 kGy) optimised the sensory quality, on the 3rd day of storage (p vacuum packaging combined to a low-dose gamma-irradiation (1.5 kGy) on chub mackerel is recommended to enhance microbiological quality (4 log reduction), alleviate chemical changes and extend the shelf-life by 7 days, leading to consumer appreciation of these products.

    The efficacy of cabergoline in Cushing's disease (CD) is controversial. The aim of this study was to assess the efficacy and tolerability of cabergoline in a large contemporary cohort of patients with CD. We conducted a retrospective multicenter study from thirteen French and Belgian university hospitals. Sixty-two patients with CD received cabergoline monotherapy or add-on therapy. Symptom score, biological markers of hypercortisolism and adverse effects were recorded. Twenty-one (40%) of 53 patients who received cabergoline monotherapy had normal urinary free cortisol (UFC) values within 12 months (complete responders), and five of these patients developed corticotropic insufficiency. The fall in UFC was associated with significant reductions in midnight cortisol and plasma ACTH, and with clinical improvement. Compared to other patients, complete responders had similar median baseline UFC (2.0 vs 2.5xULN) and plasma prolactin concentrations but received lower doses of cabergoline (1.5 vs 3.5 mg/week, P 12 months), cabergoline was withdrawn in 28% of complete responders because of treatment escape or intolerance. Overall, sustained control of hypercortisolism was obtained in 23% of patients for 32.5 months (19-105). Nine patients on steroidogenesis inhibitors received cabergoline add-on therapy for 19 months (1-240). Hypercortisolism was controlled in 56% of these patients during the first year of treatment with cabergoline at 1.0 mg/week (0.5-3.5). About 20-25% of CD patients are good responders to cabergoline therapy allowing long-term control of hypercortisolism at relatively low dosages and with acceptable tolerability. No single parameter, including the baseline UFC and prolactin levels, predicted the response to cabergoline. © 2017 European Society of Endocrinology.

    Measurement of the plasma adrenocorticotropic hormone (ACTH) level has been recommended as the first diagnostic test for differentiating between ACTH-independent Cushing syndrome (CS) and ACTH-dependent CS. When plasma ACTH values are inconclusive, a differential diagnosis of CS can be made based upon measurement of the serum dehydroepiandrosterone sulfate (DHEA-S) level and results of the high-dose dexamethasone suppression test (HDST). The aim of this study was to assess the utility of plasma ACTH to differentiate adrenal CS from Cushing' disease (CD) and compare it with that of the HDST results and serum DHEA-S level. We performed a retrospective, multicenter study from January 2000 to May 2012 involving 92 patients with endogenous CS. The levels of plasma ACTH, serum cortisol, 24-hour urine free cortisol (UFC) after the HDST, and serum DHEA-S were measured. Fifty-seven patients had adrenal CS and 35 patients had CD. The area under the curve of plasma ACTH, serum DHEA-S, percentage suppression of serum cortisol, and UFC after HDST were 0.954, 0.841, 0.950, and 0.997, respectively (all P<0.001). The cut-off values for plasma ACTH, percentage suppression of serum cortisol, and UFC after HDST were 5.3 pmol/L, 33.3%, and 61.6%, respectively. The sensitivity and specificity of plasma ACTH measurement were 84.2% and 94.3%, those of serum cortisol were 95.8% and 90.6%, and those of UFC after the HDST were 97.9% and 96.7%, respectively. Significant overlap in plasma ACTH levels was seen between patients with adrenal CS and those with CD. The HDST may be useful in differentiating between these forms of the disease, especially when the plasma ACTH level alone is not conclusive.

    Late-night salivary cortisol (LNSC) is well-validated in the diagnosis of Cushing's disease (CD). The accuracy of LNSC during follow-up of patients undergoing transsphenoidal surgery (TSS) has not been fully characterized. We examined the accuracy of LNSC in establishing remission and identifying recurrence in postoperative patients with CD. This is a retrospective study. Records of patients with CD who underwent TSS by a single neurosurgeon in our tertiary center (2005-2014) were analyzed (N = 224). Patients were selected for further investigation (n = 165) if there was at least one available LNSC test obtained after TSS (either within 3 months or during long-term follow-up). Extracted data included demographic and clinical characteristics, magnetic resonance imaging and laboratory data (morning serum cortisol, 24-hour urine free cortisol [UFC], LNSC) . Remission was defined as nadir morning serum cortisol less than 5 mcg/dl and nadir 24-hour UFC less than 23 mcg. Recurrence was considered definite if confirmed surgically or prompted radiotherapy. Surgical remission occurred in 89% of 89 patients with available LNSC data. LNSC, obtained within 3 months of TSS, established remission with 94% sensitivity and 80% specificity at a cutpoint of 1.9 nmol/l (area under the curve [AUC] = 0.90). At a median follow-up of 53.5 months, LNSC established recurrence (75% sensitivity and 95% specificity) at a cutpoint of 7.4 nmol/l (AUC = 0.87), and 24-hour UFC established recurrence (68% sensitivity and 100% specificity) at a cutpoint of 1.6-fold above normal (AUC = 0.82). LNSC may accurately establish remission after TSS and identify recurrence more accurately than 24-hour UFC during long-term follow-up.

    Computer architecture is transiting from the multicore era into the heterogeneous era in which heterogeneous architectures use on-chip networks to access shared resources and how a network is configured will likely have a significant impact on overall performance and power consumption. Recently, heterogeneous network on chip (NoC) has been proposed not only to achieve performance comparable to that of the NoCs with buffered routers but also to reduce buffer cost and energy consumption. However, heterogeneous NoC design for heterogeneous GPU-CPU architectures has not been studied in depth. This paper first evaluates the performance and power consumption of a variety of static hot-potato based heterogeneous NoCs with different buffered and bufferless router placements, which is helpful to explore the design space for heterogeneous GPU-CPU interconnection. Then it proposes Unidirectional Flow Control (UFC), a simple credit-based flow control mechanism for heterogeneous NoC in GPU-CPU architectures to control network congestion. UFC can guarantee that there are always unoccupied entries in buffered routers to receive flits coming from adjacent bufferless routers. Our evaluations show that when compared to hot-potato routing, UFC improves performance by an average of 14.1%with energy increased by an average of 5.3%only.

    Investigations on the relationship between obesity, binge eating and the function of hypothalamic-pituitary-adrenal (HPA) axis have led to inconsistent results. General psychopathology affects HPA axis function. The present study aims to examine correlations between binge eating, general psychopathology and HPA axis function in obese binge eaters. Twenty-four hour urinary free cortisol (UFC/24 h) was measured in 71 obese binge eating women. The patients were administered psychometric tests investigating binge eating, psychopathology and clinical variables. The relationship between binge eating, psychopathology and urinary cortisol was investigated, controlling for age and BMI. We found an inverse correlation between UFC/24 h and binge eating, depression, obsessive-compusive symptoms, somatization and sensitivity. In a regression model a significant inverse correlation between urinary cortisol and psychopathology was confirmed. Urinary cortisol levels in obese patients with binge eating disorder show an inverse correlation with several dimensions of psychopathology which are considered to be typical of a cluster of psychiatric disorders characterized by low HPA axis function, and are very common in obese binge eating patients. If these results are confirmed, UFC/24 h might be considered a biomarker of psychopathology in obese binge eaters. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available El Ensayo Bactericida del Suero (EBS, está considerado como la “prueba de oro” para evaluar la eficacia serológica de vacunas antimeningocócicas, teniendo en cuenta que la presencia de anticuerpos bactericidas en el suero se relaciona con la protección frente a esta enfermedad. Los niveles de anticuerpos anticapsulares obtenidos frente a los serogrupos A y C de Neisseria meningitidis han confirmado la utilidad de esta técnica. Sin embargo, se señala una pobre correlación entre los resultados de laboratorio y la protección clínica demostrada después de la aplicación de vacunas compuestas por vesículas de membrana externa del serogrupo B. Ison y colaboradores desarrollaron el Ensayo de Sangre Total (EST, que evalúa la capacidad bactericida de la sangre. Los resultados obtenidos indican que es un marcador de inmunidad más sensible que el EBS para el serogrupo B. En un estudio de evaluación de la vacuna antimeningocócica cubana VA-MENGOC-BC®, realizado en infantes y empleando el EST, se obtuvo un 50% de respondedores a la cepa homóloga (B:4:P1.19,15. La respuesta contra cepas heterólogas resultó baja. Teniendo en cuenta estos resultados y los de otros estudios realizados por los autores, se evaluó el comportamiento de la prueba utilizando concentraciones menores de la suspensión bacteriana empleada como inóculo. Para este propósito se estudió la actividad bactericida de la sangre de dos adultos sanos, mediante el EST frente a las cepas B:4:P1.19,15 (Cu 385/83 y B:15:P1.7,16 (MC58. Se evaluaron, además de la concentración recomendada originalmente (106ó107 UFC/mL, dos inferiores (105 y 104 UFC/mL. El primer donante mostró una actividad lítica del 40% frente a la cepa homóloga, a una concentración de inóculo de 107 UFC/mL. Para las concentraciones de 105 y 104 UFC/mL la lisis fue de alrededor del 80%. El comportamiento frente a la cepa heteróloga fue de un 25% de lisis a la mayor concentración del inóculo y

  17. Bacterial, fungal and yeast contamination in six brands of irreversible hydrocolloid impression materials Contaminação por bactérias, fungos e leveduras em seis marcas comerciais de materiais de moldagem à base de hidrocolóide irreversível

    Full Text Available This study assessed the level of contamination of six commercially available irreversible hydrocolloids (two containing chlorhexidine and identified the contamination present in the materials. Petri dishes containing selective and enriched culture media were inoculated with alginate powder (0.06 g, in triplicate. After incubation (37°C/7 days, the colony-forming units (CFU were counted and Gram stained. Biochemical identification of the different morphotypes was also performed. The contamination levels for the materials were: Jeltrate - 389 CFU/g; Jeltrate Plus - 516 CFU/g; Jeltrate Chromatic - 135 CFU/g; Hydrogum - 1,455 CFU/g; Kromopan - 840 CFU/g; and Greengel - 59 CFU/g. Gram staining revealed the presence of Gram-positive bacillus and Gram-positive cocci. The bacteria Staphylococcus epidermidis, Bacillus subtilis, Bacillus sp., Bacillus coagulans, Bacillus licheniformis, Bacillus cereus, Micrococcus luteus, and Nocardia sp.; the filamentous fungi Aspergillus niger, Aspergillus flavus, Rhizopus sp., Neurospora sp.; and the yeast Candida sp. were isolated. The contamination detected in the impression materials points out the need for adopting measures to improve the microbiological quality of these materials. The use of contaminated materials in the oral cavity goes against the basic principles for controlling cross-contamination and may represent a risk for debilitated or immunocompromised patients.Este estudo avaliou o nível de contaminação de seis marcas comerciais de alginato (duas contendo clorexidina e identificou a contaminação presente nesses materiais. Alíquotas de alginato (0,06 g foram semeadas em meios de cultura seletivos e enriquecidos, em triplicata. Após incubação (37°C/7 dias, as unidades formadoras de colônia (UFC foram contadas e foram realizadas as identificações morfotintorial (Gram e bioquímica.

  18. Periodization and Its Discontents: The Social Construction of Crime and Criminality in Modern Mexico

    OpenAIRE

    Buffington, Robert

    2003-01-01

    This paper gives an overview of four phases in the social construction of crime and criminality in Mexico since the Independence era. It argues that these phases follow a pattern in which a criminal justice paradigm is gradually consolidated and eventually superseded. It then examines some of the problems with a paradigm-driven periodization.

    When a honeybee queen starts to fail, she is often superseded by a young queen that takes over reproduction inside the colony. Natural supersedure in winter leads to an unfertilised young queen and colony loss. To reduce these losses we tried to stimulate supersedure of queens earlier in the season.

It was determined the losses during the fermentation and air exposition phases. The DM, and ammonia nitrogen contents, pH values, yeast and fungal populations were determined during the silage fermentation, and air exposition phase. The data were analyzed according to a randomized block design, in a split plot schedule with four replications. The L. buchneri utilization did not affect the corn grain fermentation, but controlled the yeast and fungal growth. It was recorded average pH values (4.2, gas losses (2.68%, and effluent (2.56 kg/t of silage and RMS (98.24%.

  5. Peritoneal transport characteristics with glucose polymer based dialysate.

    /PNa+ decreased with 3.86% glucose until 60 minutes, followed by a subsequent increase. The ultrafiltration coefficient (UFC) of the total peritoneal membrane was assessed using 3.86% glucose (0.18 +/- 0.04 ml/min/mm Hg), and the UFC of the small pores was assessed using icodextrin (0.06 +/- 0.008 ml/min/mm Hg). The difference between these represented the UFC through the transcellular pores, which averaged 50.5% of the total UFC, but with a very wide range (0 to 85%). An inverse relation existed between the duration of CAPD treatment and the total ultrafiltration coefficient (r = -0.68, P < 0.04), which could be attributed to a lower UFC of the transcellular pores in long-term patients (r = -0.66, P < 0.05), but not to the UFC of the small pores (r = -0.48, NS). The TCUFRo-60 min through the transcellular pores correlated with the sodium gradient, corrected for diffusion, in the first hour of the dwell (r = 0.69, P < 0.04), indicating that both parameters indeed measure transcellular water transport. It can be concluded that the glucose polymer solution induced sustained ultrafiltration and had no effect on peritoneal membrane characteristics. In addition, the results of the present study support the hypothesis that the glucose polymer solutions exerts its osmotic pressure across intercellular pores with radii of about 40 A. This leads to increased clearances of low molecular weight proteins such as beta 2m that are transported through these pores without sieving of Na+. The latter, as found during 3.86% glucose dialysate, is probably caused by transcellular water transport. The transcellular water transport accounted for 50% of the total ultrafiltration with glucose based dialysis solutions. It was lower in long-term CAPD patients.

    Cushing's disease (CD) is associated with increased morbidity and mortality. Until now, no medical treatment has been shown to be totally satisfactory when administrated alone. This study aimed to assess the effectiveness of cabergoline with added ketoconazole and of the same combination in reverse, using urinary free cortisol (UFC) and late night salivary cortisol (LNSC) levels as biochemical markers of the treatments' efficacy in CD patients. A prospective analysis conducted on 14 patients (f/m = 12/2; median age 52, range 33-70 years) divided into two groups: 6 patients initially treated with cabergoline for 4-6 months (rising from 0.5-1 mg/week up to 3.0 mg/week), after which ketoconazole was added (group A); and 8 patients first took ketoconazole alone for 4-6 months (rising from 200 mg/day to 600 mg/day), then cabergoline was added (group B). Patients were compared with 14 age-matched patients in prolonged remission after effective neurosurgery for CD. The combination therapy led to UFC normalization in 79 % of patients with no differences between the groups; only one patient failed to respond at all. Neither drug succeeded in controlling the disease when taken alone. LNSC dropped when compared to baseline levels, but not to a significant degree (p = 0.06), and it remained significantly higher than in controls (p = 0.0006). Associating cabergoline with ketoconazole may represent an effective second-line treatment, achieving a satisfactory reduction in UFC levels and clinical improvement. Although the combined treatment lowered patients' LNSC levels, they remained higher than normal, indicating a persistent subclinical hypercortisolism; the implications of this condition need to be considered. No differences emerged between the two treatment schedules.

    Chronic exposure to environmental stress may play a role in the development of obesity, through hyperactivation of the hypothalamic-pituitary-adrenocortical (HPA) axis. This study investigated the dynamics of weight gain and the activity of the HPA axis in women who developed weight gain after a stressful event. This is a case-control retrospective study. Two groups of age-matched premenopausal women were selected. One (n = 14) included women characterized by a rapid weight gain following a stressful event, defined as the "stress-related obesity " (SRO) group, and the other (n = 21) women with nonstress-related development of obesity, defined as the "nonstress-related obesity " (NSRO) group. Twenty-one healthy premenopausal women served as normal-weight controls. Baseline hormonal and metabolic parameters, and 24-h urinary free cortisol (UFC/24 h) excretion rate (as a measure of HPA-axis activity) were measured in all women. Anthropometry, diet, and physical activity were similar in both obese groups. Both obese groups showed similar metabolic and hormonal profiles, but the SRO group had UFC/24 h values (41.1 +/- 14.3 microg) significantly higher (P < 0.001) with respect to the NSRO (26.6 +/- 17.6 microg) or the normal-weight control groups (21.1 +/- 9.8 microg). Moreover, time (years) to achieve maximum Deltaweight gain (kg) and the Deltaweight gain/time ratio were significantly shorter (P < 0.001) and higher (P < 0.001) in the SRO group with respect to the NSRO group, respectively. In the SRO group, there was a tendency to a significant correlation between UFC/24 h and the Deltaweight gain/time ratio. These findings support the concept that SRO has distinct pathophysiological mechanisms, including hyperactivity of the HPA axis.

    Full Text Available Cushing’s syndrome is associated with increased morbidity and mortality. Although surgery is the first-line treatment, drugs can still play a role as an ancillary treatment to be employed while waiting for surgery, after unsuccessful operation or in patients unsuitable for surgery. We were asked to evaluate a 32-year-old male waiting for cardiac transplantation. Idiopathic hypokinetic cardiomyopathy had been diagnosed since 6 years. He was on treatment with multiple drugs, had a pacemaker, an implantable cardioverter and an external device for the support of systolic function. Physical examination showed severely impaired general status, signs of hypercortisolism and multiple vertebral compression fractures. We administered teriparatide, and the few evaluable parameters supported the diagnosis of ACTH-dependent hypercortisolism: serum cortisol was 24.2 μg/dL in the morning and 20.3 μg/dL after overnight 1 mg dexamethasone, urinary free cortisol (UFC was 258 μg/24 h and ACTH 125 pg/mL. Pituitary CT was negative. Pasireotide 300 μg bid was administered and uptitrated to 600 μg bid. Treatment was well tolerated, achieving dramatic improvement of clinical picture with progressive normalization of serum cortisol and ACTH levels as well as UFC. After 4 months, the patient underwent successful heart transplantation. Many complications ensued and were overcome. Pituitary MRI was negative. On pasireotide 300 μg bid and prednisone 2.5 mg/day (as part of immunosuppressive therapy, morning serum cortisol and ACTH were 15.6 μg/dL and 54 pg/mL respectively, UFC was 37 μg/24 h, fasting glucose: 107 mg/dL and HbA1c: 6.5%. In conclusion, primary treatment with pasireotide achieved remission of hypercortisolism, thus allowing the patient to undergo heart transplantation.

    The use of ketoconazole has been recently questioned after warnings from the European Medicine Agencies and the Food and Drug Administration due to potential hepatotoxicity. However, ketoconazole is frequently used as a drug to lower circulating cortisol levels. Several pharmacological agents have recently been approved for the treatment of Cushing's disease (CD) despite limited efficacy or significant side effects. Ketoconazole has been used worldwide for more than 30 years in CD, but in the absence of a large-scale study, its efficacy and tolerance are still under debate. We conducted a French retrospective multicenter study reviewing data from patients treated by ketoconazole as a single agent for CD, with the aim of clarifying efficacy and tolerance to better determine the benefit/risk balance. Data from 200 patients were included in this study. At the last follow-up, 49.3% of patients had normal urinary free cortisol (UFC) levels, 25.6% had at least a 50% decrease, and 25.4% had unchanged UFC levels. The median final dose of ketoconazole was 600 mg/d. Forty patients (20%) received ketoconazole as a presurgical treatment; 40% to 50% of these patients showed improvement of hypertension, hypokalemia, and diabetes, and 48.7% had normal UFC before surgery. Overall, 41 patients (20.5%) stopped the treatment due to poor tolerance. Mild (5N, superior to 5-fold normal values) increases in liver enzymes were observed in 13.5% and 2.5% of patients, respectively. No fatal hepatitis was observed. Ketoconazole is an effective drug with acceptable side effects. It should be used under close liver enzyme monitoring. Hepatotoxicity is usually mild and resolves after drug withdrawal.

    The purpose of this one-year investigation is to perform a technology integration/search, thereby ensuring that the safest and most cost-effective options are developed and subsequently used during the deactivation and decommissioning (D&D) of U.S. Department of Energy Environmental Management (DOE-EM) sites. Issues of worker health and safety are the main concern, followed by cost. Two lines of action were explored: innovative Personal Cooling Systems (PCS) and Personal Monitoring Equipment (PME). PME refers to sensors affixed to the worker that warn of an approaching heat stress condition, thereby preventing it. Three types of cooling systems were investigated: Pre-Chilled or Forced-Air System (PCFA), Umbilical Fluid-Chilled System (UFCS), and Passive Vest System (PVS). Of these, the UFCS leads the way. The PVS or Gel pack vest lagged due to a limited cooling duration. And the PCFA or chilled liquid air supply was cumbersome and required an expensive and complex recharge system. The UFCS in the form of the Personal Ice Cooling System (PICS) performed exceptionally. The technology uses a chilled liquid circulating undergarment and a Personal Protective Equipment (PPE) external pump and ice reservoir. The system is moderately expensive, but the recharge is low-tech and inexpensive enough to offset the cost. There are commercially available PME that can be augmented to meet the DOE's heat stress alleviation need. The technology is costly, in excess of $4,000 per unit. Workers easily ignore the alarm. The benefit to health & safety is indirect so can be overlooked. A PCS is a more justifiable expenditure.

    The objective of this study is to infer the survival of the probiotic Lactobacillus paracasei ssp paracasei added during the processing of low-fat Gouda cheese, during the maturation (21 days) and the commercialization (14 days), in order to see the influence that this organism has on the quality of the product. The treatments were: TI (control): Gouda with normal fat content; T2: Low fat Gouda cheese (QGS) T3: QGS, with additional probiotic added with the initial culture; T4: QGS, with the probiotic added in the cooking of the curd. For the count of the probiotic, the methodology was used set forth by the American Public Health Association, (APHA), proteolysis by the method of soluble tyrosine in trichloroacetic acid (TCA), and the physical and chemical analysis using the methods standardized by the International Dairy Federation, and Chilean normative. The counts obtained were from 10(8) ufc/g y 10(7) ufc/g in the cheeses that had the probiotic additive (T3 and T4, respectively) close to the level of innocuous (10(8) ufc/g) during the study period of 35 days. The proteolysis incremented normally, and was the same in all of the treatments during the 35 days studied. The treatments with fat-reduction presented approximately, 31% less fat than the control treatment, and also higher moistness. Within the treatments, there was no evidence of taste and general feel; in turn the cheeses with the reduction of fat resulted firmer, less cohesive, than the control, and with similar elasticity.

    Highlights: • A novel Used Fuel Container with an integrally bonded copper coating is proposed. • Two developed coating processes successfully produced prototype container components. • We created a validated finite element model to predict coating structural performance. • Mechanical testing confirms coating suitably for repository use. - Abstract: The preferred method for disposal of used nuclear fuel is underground emplacement in a Deep Geological Repository (DGR). Many countries have light water reactor fuels which require large Used Fuel Container or Canister (UFC) designs weighing up to 25 ton for containment. In contrast, Canada exclusively uses heavy water reactor fuel, which is substantially smaller. This has led the Nuclear Waste Management Organization (NWMO) to create a novel UFC, which uses standard pressure vessel grade steel for structural containment and a thick, integrally bonded copper coating applied to the exterior surface for corrosion protection. Currently, the coating is applied using two different methods: electrodeposition and gas dynamic cold spray. This novel copper coating needs to be fully validated to ensure adequate mechanical strength and chemical resistance for use under repository conditions. Detailed mechanical and corrosion testing programs were undertaken. Mechanical tests indicated that adhesion strengths exceeded 45 MPa and tensile properties were comparable to wrought copper. A Finite Element Model (FEM) of the copper–steel composite was created and validated using three point bend tests. This model accurately predicts the response of the composite, including large deformation and debonding failure mechanisms. Now validated, this model will be used to assess the performance of the coating on the full-scale UFC under simulated DGR loading conditions.

    Full Text Available RESUMO: Em Santos, litoral de São Paulo, a avaliação da qualidade microbiológica da água das praias é realizada pela prefeitura e pela Companhia Ambiental do Estado de São Paulo (CETESB. Entretanto, a mesma atenção não é direcionada à areia das praias. A areia representa um potencial vetor de contaminação e pode constituir reservatório de microrganismos patogênicos. O objetivo deste estudo foi avaliar a qualidade microbiológica da areia das praias de Santos, São Paulo. Utilizou-se a técnica das membranas filtrantes para os grupos de coliformes fecais (Escherichia coli e enterococos. As amostras foram coletadas em sete pontos das praias de Santos. Os ensaios foram realizados mensalmente durante 8 meses e os resultados, expressos em unidades formadoras de colônias (UFC de bactérias por 100 g de areia, variaram de 40.000 a 2.700.000 para E. coli e de não detectado a 95.000 para enterococos, encontrando-se acima dos valores orientadores existentes em âmbito nacional (3.800 UFC.100g-1 - Rio de Janeiro e internacional (100.000 UFC.100g-1 - Portugal. O contato com areia contaminada pode causar diversas doenças, comprometendo a qualidade de vida da população. Torna-se importante a realização de estudos baseados em evidências epidemiológicas de exposição e análises de risco, para se estabelecer padrões de qualidade e políticas públicas para monitoramento e gerenciamento da qualidade sanitária da areia das praias do litoral de São Paulo.

    Full Text Available Blast Resistant Doors are used to withstand high intensity impulsive blast loads. They are designed to prevent the impact of the blast from travelling from one side to the other side of the door. Taking into account the limitations and the growing need of efficient blast resistant doors, a design was developed using ASTM A36 as the material of construction instead of concrete. Analytical calculations for the actual pressure-impulse loading condition were done as per the UFC 3-340-02, and the results of analytical calculations were compared with results of the simulation of the numerical model for the given boundary conditions.

    Full Text Available Learning technology has yet to enter the mainstream of higher education. The UFC-funded Teaching and Learning Technology (TLT programme is attempting to change this by sponsoring projects concerned with courseware production and delivery. These efforts could be thwarted if the Not Invented Here syndrome prevents the use of technology-based teaching and learning materials outside the originating departments. To gain a clearer understanding of why academics have been rejecting much existing courseware, and to establish the extent of the Not Invented Here syndrome, we carried out a survey of 800 academics in eight UK universities. The survey proved to be exceptionally revealing.

Se utilizó información cualitativa referente a diversas variables de manejo para producir leche. Se analizaron 108 productores, mediante análisis de correspondencias múltiples y análisis de conglomerados. Se identificó 4 formas de obtener leche. El grupo SP1 (43% de la muestra aportó el 87% de la leche a la industria y presentó adecuadas formas de manejo, clasificando todos, el 100% de sus partidas de leche en el mejor rango de calidad (≤ 20.000 ufc/mL. El SP2 (20% de la muestra aportó un 10% del total de leche aunque mayoritariamente presentó inadecuadas formas de manejo, y clasificó un 77% de las partidas de leche en el mejor rango de calidad (≤ 20.000 ufc/mL, esta inconsistencia sugiere la necesidad de analizar en mayor profundidad este grupo. Finalmente, los grupos SP3 y SP4, que en conjunto entregaron sólo un 3% de la leche de la muestra total a la industria pero que representaron un 37% de la muestra, presentaron inadecuadas formas de manejo y se consideraron "grupos problema", predominando en ambos partidas de leche de mala calidad con recuentos > 200.000 ufc/mL en un 76 y 72%, respectivamente, en especial en SP3 con un 61% de las partidas de leche clasificadas en el peor rango establecido (> 800.000 ufc/mL. Consecuentemente se deben realizar acciones correctivas, relacionadas fundamentalmente con la temperatura de almacenamiento de la leche y con el correcto lavado de equipos, estanques y utensilios en SP3 y SP4.

    Full Text Available Este trabajo validó la técnica de PCR para la detección de L. monocytogenes a partir de ADN de cultivos puros y en muestras de leches crudas, quesos frescos, carne de res y carne de pollo. En DNA de cultivos puros la sensibilidad, la especificidad y la reproducibilidad encontrada fue de 100%, 101UFC/ml y K=1,respectivamente. Para la extracción del ADN de los alimentos se emplearon dos métodos, el primero, basado en la precipitación alcohólica en presencia de NaI, lo que redujo en gran medida las grasas; permitiendo la detección directa de 10 1 UFC/ml en leche cruda y 105 UFC/g en queso fresco. El segundo método, basado en la extracción con lisozima, proteinasa K y fenol-cloroformo, permitió establecer límites de detección de 102 y 104 UFC/g para las carnes de res y pollo respectivamente. La PCR se basó enla especificidad de los iniciadores LI1/U1 que amplificaron una banda de 938 pb (identificación de género característica del rDNA 16S y los iniciadores LF/LR que amplificaron una banda de 750 pbcaracterística del gen hlyA (identificación de especie. Los resultados de la validación reportaron con relación al método “Gold Standard” una reproducibilidad, sensibilidad y especificidad del 100% en leches crudas. Para las muestras de queso frescos se reportó una reproducibilidad de 97%, sensibilidad 96.3% y especificidad del 100%, para la carne de pollo la reproducibilidad fue 98.43%, sensibilidad96.9%, especificidad 100%, valor predictivo positivo 100% y valor predictivo negativo 100%, para la carne de res todos los parámetros fueron 100%. El método “Gold Standard” reportó 100% para todos losparámetros. El trabajo muestra que ambas técnicas pueden ser utilizadas para detectar L. monocytogenes en este tipo de alimentos y que la PCR reduce el tiempo de ensayo considerablemente.

    Full Text Available Realizing the cause of Cushing's Syndrome (CS is one of the most challenging processes in clinical endocrinology. The long high dose dexamethasone suppression test (standard test is costly and need an extended inpatient stay. In this study we want to show the clinical utility of the overnight 8 mg dexamethasone suppression test (DST for differential diagnosis of CS in a referral center. Retrospectively from 2002-2005 we selected the patients of endocrinology ward in Imam hospital who were admitted with the diagnosis of Cushing syndrome and had 8 mg DST (modified test along with classic DST. In modified test a decrease in an 8 AM serum cortisol level of 50% or more is thought to indicate suppression and we compared the results of modified test with standard test. This test had been done on 42 patients: 10 male (23% and 32 female (76%. The mean age of patients was 31.39 (15-63, 32 with proven pituitary Cushing's disease, 7 with primary adrnal tumors and 3 with ectopic ACTH syndrome. The standard test according to 50% suppression of UFC had 90.62% sensitivity, and according to 90% suppression had 43.75% sensitivity. The sensitivity of this test was 71.85% for serum cortisol suppression. The modified test (8 mg overnight DST had 78% sensitivity. All of these tests had 100% specificity for the diagnosis of Cushing's disease. The positive predictive vale (PPV of all of these tests was 100%. The negative predictive value (NPV of modified test for the diagnosis of Cushing's disease was 58.82%. In standard test the NPV of serum cortisol was 52.6%, UFC 50% had 76.9% NPV and UFC 90% had 35.7% NPV. The results of serum cortisol suppression in modified test is better than standard test. Although 50% suppression of UFC in standard test had greater sensitivity than modified test, collecting of urine is difficult, time consuming and needing hospitalization, so we advice modified test that is much simpler and more convenient instead of standard test in the first

    Full Text Available Brucella abortus es una bacteria que causa abortos e infertilidad en el ganado y fiebre ondulante en el hombre. Se multiplica en el citoplasma celular evadiendo los mecanismos de muerte intracelular. El óxido nítrico (NO es importante en la regulación de la respuesta inmune. En el presente trabajo estudiamos la habilidad de tres cepas de B. abortus para sobrevivir intracelularmente en dos líneas celulares de macrófagos. La multiplicación de bacterias en ambas líneas celulares fue determinada a distintos tiempos en número de UFC/ml, también fue observada al microscopio de campo claro y de fluorescencia utilizando Giemsa y naranja de acridina, respectivamente. La tinción de ambas líneas celulares inoculadas con B. abortus mostró un resultado concordante con el encontrado en la determinación del número de UFC. Fue confirmada la presencia de B. abortus por microscopía electrónica. Para medir la producción de NO se utilizó el reactivo de Griess. La multiplicación de la cepa rugosa RB51 disminuyó en ambas líneas celulares y los niveles de NO fueron mayores en células inoculadas con dicha cepa que cuando fueron inoculadas con las cepas lisas (S19 y 2308. Estos resultados sugieren que probablemente la ausencia de cadena O en el lipopolisacárido afecta el crecimiento intracelular de B. abortus.Brucella abortus is a bacterium which causes abortions and infertility in cattle and undulant fever in humans.

    Fifty samples of cereals including 30 of wheat (10 of wheat hard red spring), 10 of wheat soft red winter and 10 of wheat durum ámber), 10 of barley and 10 of corn (5 of white corn and 5 of yellow corn) were analyzed to detect and determine by the TLC method, the quantity of deoxynivalenol levels, which is a toxic secondary metabolite produced by Fusarium species. The aw of samples and the internal and external micoflora and Fusarium spp. levels were also investigated. Results showed that the highest grade of infection (12-80%), and the highest count of total molds (3.9 Log UFC/g) were detected in wheat samples, while the highest levels of Fusarium spp. (2.3 Log UFC/g) were detected in white corn. Deoxynivalenol was found in the wheat and barley samples but not in corn. The wheat red winter soft samples showed the highest levels of deoxynivalenol (3.2 ug/g) which is over the limit levels accepted by the FDA. Correlation was not found among count of total molds, Fusarium spp., infestation grade, aw, and deoxynivalenol levels. These results suggest that it is necessary to exert measures to avoid and to control the importation of contaminated cereals with DON levels higher to those allowed.

    Fractal image compression is a promising technique to improve the efficiency of image storage and image transmission with high compression ratio, however, the huge time consumption for the fractal image coding is a great obstacle to the practical applications. In order to improve the fractal image coding, efficient fractal image coding algorithms using a special unified feature and a DCT coder are proposed in this paper. Firstly, based on a necessary condition to the best matching search rule during fractal image coding, the fast algorithm using a special unified feature (UFC) is addressed, and it can reduce the search space obviously and exclude most inappropriate matching subblocks before the best matching search. Secondly, on the basis of UFC algorithm, in order to improve the quality of the reconstructed image, a DCT coder is combined to construct a hybrid fractal image algorithm (DUFC). Experimental results show that the proposed algorithms can obtain good quality of the reconstructed images and need much less time than the baseline fractal coding algorithm.

    Three different irrigation regimes - upper limit of field capacity (UFC), -12 kPa); lower limit of field capacity (LFC), -33 kPa; and deficit irrigation (DI), -70 kPa) were established on silty-loam soil and monitored with tensiometers. Yield and fruit quality of 'Flamenco' and 'Eva's Delight' ever-bearing strawberry cultivars were monitored. The aim of the study was to evaluate the effect of different irrigation regimes on the content of sugars, organic acids and phenolic compounds using high-performance liquid chromatography-mass spectrometry HPLC/HPLC-MS. Deficit irrigation significantly increased the content of sugars (from 1.1- to 1.3 fold), organic acids (from 1.1- to 1.3-fold), their ratio (from 1.1- to 1.2-fold) and the content of most identified phenolics in cv. 'Flamenco'. Conversely, higher amounts of total sugars and organic acids (1.7- to 1.8-fold) were detected in 'Eva's Delight' strawberries at UFC and LFC irrigation. Deficit irrigation generally decreased strawberry yield of cv. 'Eva's Delight'. The results suggest superior fruit quality and taste of strawberries grown under minor deficit irrigation for cv. 'Flamenco'. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

  1. Modeling the Residual Strength of a Fibrous Composite Using the Residual Daniels Function

    2016-09-01

    The concept of a residual Daniels function (RDF) is introduced. Together with the concept of Daniels sequence, the RDF is used for estimating the residual (after some preliminary fatigue loading) static strength of a unidirectional fibrous composite (UFC) and its S-N curve on the bases of test data. Usually, the residual strength is analyzed on the basis of a known S-N curve. In our work, an inverse approach is used: the S-N curve is derived from an analysis of the residual strength. This approach gives a good qualitive description of the process of decreasing residual strength and explanes the existence of the fatigue limit. The estimates of parameters of the corresponding regression model can be interpreted as estimates of parameters of the local strength of components of the UFC. In order to approach the quantitative experimental estimates of the fatigue life, some ideas based on the mathematics of the semiMarkovian process are employed. Satisfactory results in processing experimental data on the fatigue life and residual strength of glass/epoxy laminates are obtained.

The design was completely randomized with four replications in a 3 × 2 factorial arrangement, with three sources of soluble carbohydrates (SC, control, 50 g sucrose/kg or 50 g crude glycerin/kg as fed and two doses of microbial inoculants (MI, 0 or 5 × 10(5 ufc Lactobacillus plantarum + 3.33 × 10(5 ufc Propionibacterium per g as fed. Twenty-four mini-silos (982 cm³ of polyvinyl chloride were created and opened after 60 days of fermentation at room temperature. The pre-hydrated Jatropha curcas L. cake (282 g of water/kg contained 0.424 mg of phorbol esters/g of dry matter. Ensiling reduced the phorbol esters in 47.4%, on average, regardless of the SC or MI. There was no interaction effect between SC and MI on effluent, gases or total dry matter losses. However, both losses were increased when SC were added, and it was higher with glycerin that than sucrose. The addition of MI reduced all fermentation losses. The process of ensiling, although partially to reduce the phorbol esters of pre-hydrated Jatropha curcas L. cake, is not indicated as a biodestoxification procedure.

    This work evaluates the effect of acetic acid dipping on the growth of L. monocytogenes on poultry legs stored at 4 °C for eight days. Fresh inoculated chicken legs were dipped into either a 1% or 2% acetic acid solution (v/v) or distilled water (control). Changes in mesophiles, psychrotrophs, Enterobacteriaceae counts and sensorial characteristics (odor, color, texture and overall appearance) were also evaluated. The shelf life of the samples washed with acetic acid was extended by at least two days over the control samples washed with distilled water. L. monocytogenes counts before decontamination were 5.57 log UFC/g, and after treatment with 2% acetic acid (Day 0), L. monocytogenes counts were 4.47 log UFC/g. Legs washed with 2% acetic acid showed a significant (p acetic acid. This study demonstrates that while acetic acid did reduce populations of L. monocytogenes on meat, it did not completely inactivate the pathogen. The application of acetic acid may be used as an additional hurdle contributing to extend the shelf life of raw poultry and reducing populations of L. monocytogenes.

    Transsphenoidal surgery (TSS) is the treatment of choice for Cushing's disease (CD). However, the best treatment option when hypercortisolism persists or recurs remains unknown. The aim of this study was to analyze the short and long-term outcome of repeat TSS in this situation and to search for response predictors. Data from 26 patients with persistent (n=11) or recurrent (n=15) hypercortisolism who underwent repeat surgery by a single neurosurgeon between 1982 and 2009 were retrospectively analyzed. Remission was defined as normalization of urinary free cortisol (UFC) levels, and recurrence as presence of elevated UFC levels after having achieved remission. The following potential outcome predictors were analyzed: adrenal status (persistence or recurrence) after initial TSS, tumor identification in imaging tests, degree of hypercortisolism before repeat TSS, same/different surgeon in both TSS, and time to repeat surgery. Immediate postoperative remission was achieved in 12 patients (46.2%). Five of the 10 patients with available follow-up data relapsed after surgery (median time to recurrence, 13 months). New hormone deficiencies were seen in seven patients (37%), and two patients had cerebrospinal fluid leakage. No other major complications occurred. None of the preoperative factors analyzed was predictive of surgical outcome. When compared to initial surgery, repeat TSS for CD is associated to a lower remission rate and a higher risk of recurrence and complications. Further studies are needed to define outcome predictors.

    In the present work the effects of different brining treatments on mature table olives during natural fermentation were evaluated. The considered olive cultivars are typical of Sicily: Moresca and Giarraffa. They were harvested at pigmented state. The carpological data revealed their good quality as table olives. Natural fermentation was performed with or without acidification up to pH 4, and at 8% and 15% salt concentrations. The physical, chemical and microbiological changes in olives and brines were monitored throughout the processing period. The acidification affected and selected the microbial population and maintained the low pH necessary for the hygienic safety of the product. In fact, in Moresca brines,the lactic acid bacteria totally disappeared after 60 days of fermentation while in Giarraffa they maintained their presence in the brines up to 180 days with a value between 10{sup 4} UFC/mL and 106 UFC/mL, depending on the salt concentration. The microbial population was also affected by the polyphenol content, which was different between the cultivars. The color of olive fruits was greatly influenced by acidification and less by salt concentration. The addition of salt showed a different influence on the studied cultivars, in fact only the chemical analyses of Giarraffa showed a significant difference between the two levels of salt concentration.

    This paper describes the experimental and analytical results obtained for an MHD channel with a two dimensionally shaped magnetic field configuration called 'the SFC-type'. The power generating performance was examined under various load conditions and B-field intensities with a 2 MWt shock tunnel MHD facility. It is demonstrated that the power output performance and the enthalpy extraction scaling law of the conventional uniform B-field MHD generator (UFC-type) were significantly improved by the SFC-design of the spatial distribution of the magnetic field. The arcing processes were also examined by a high speed camera and the post-test observation of arc spot traces on electrodes. Further, the characteristic frequencies of each of the so-called micro and constricted arcs were clarified by spectral analyses. The critical current densities, which define the transient conditions of each from the diffuse-to micro arc, and from the micro-to constricted arc modes could be clearly obtained by the present spectral analysis method. We also investigated the three-dimensional behavior under strong magnetic field based on the coupled electrical and hydrodynamical equations for both of the middle scale SFC-and UFC-type generators. Finally, it is concluded from the above mentioned various aspects that the shaped 2-D magnetic field design will offer a most useful means for the realization of a compact, high efficiency and a long duration open-cycle MHD generator.

    Concerning a Faraday type MHD generator with power output 100 MWe, a parabolic three-dimensional analysis was made on the SFC type and the conventional UFC type of the applied magnetic field, comparing the electrical and fluid fields of both types. Results are as follows: (1) In Faraday type MHD generator, Hall current which is an ineffective current is suppressed by SFC magnetic field coordination. (2) In the case of UFC, a current concentration to the central anode which occurs in the large Faraday type MHD generator does not occur in the case of SFC type. (3) In SFC, a secondary flow in the electrode boundary, especially in the vicinity of the anode is weak. (4) In addition to the velocity overshoot in the dielectric wall boundary layer, in the case of SFC, it generates in the electric wall. As a result, concentrated arc columns are suppressed by the acceleration of heat transfer to the electrode wall. (13 figs, 1 tab, 13 refs)

    The utility of circadian cortisol variation in estimating the degree of hypercortisolemia in different forms of endogenous Cushing syndrome (CS) has not been evaluated in children yet. A retrospective cohort study, including children who underwent surgery due to CS (n = 115), was divided into children with a pituitary adenoma (Cushing disease) (n = 88), primary adrenal CS (n = 21), or ectopic adrenocorticotropin- or corticotropin-releasing hormone (ACTH-/CRH)-secreting tumors (n = 6). Circadian plasma cortisol measurements were obtained at 11: 30 p.m. and at midnight, and at 7: 30 and 8: 00 a.m. The ratios between the morning and late-night concentrations were calculated. Plasma cortisol early-morning and midnight (AM/PM) ratios negatively correlated with 24-h urinary free cortisol (UFC) collections among the full study population and in each of the individual etiologies. Plasma ACTH concentrations positively correlated with plasma cortisol AM/PM ratios among patients with ACTH-independent CS. Finally, patients with primary pigmented nodular adrenocortical disease showed no correlation between UFC collections and the plasma cortisol AM/PM ratio, in contrast with other etiologies for primary adrenal CS, which showed a strong negative correlation between them. Our study shows the association between the plasma cortisol AM/PM ratio and the degree of hypercortisolemia in children with CS. © 2017 S. Karger AG, Basel.

    A tubular gelatin scaffold for the time-dependent controlled release of epidermal growth factor (EGF) and mitomycin C (MMC) was fabricated. EGF was incorporated using silk fibroin carriers, and MMC was planted using polylactide (PLA) microspheres. The relationship between scaffold properties and crosslinking degrees was evaluated. As the crosslinking degree was increased from 23.7% to 65.3%, the mechanical properties of the scaffold obviously improved, and the compressive modulus increased to approximately 65kPa. The mass degradation of the scaffold was also controlled from 9 days to approximately 1 month. In vitro release tests indicated that the scaffold mainly released EGF in the early period and MMC in the later period. Urethral epithelial cells (UECs) and urethral scar derived fibroblast cells (UFCs) were coseeded in the scaffold at a ratio of 1:1. After 9 days of coculture, immunostaining results displayed that the proportion of UECs continuously increased to approximately 71%. These changes in cell proportion were confirmed by the results of Western blot analysis. Therefore, the scaffold promoted the growth but inhibited the regeneration of UFCs. This scaffold for time-dependent controlled release of multiple biofactors may be potentially useful in urethral reconstruction and other tissue engineering studies.

    Full Text Available This study aimed to evaluate the survival rate of microorganisms within different antiseptic formulations - povidone-iodine (PVP-I and chlorhexidine (CHX - after intentional contamination, and to establish the minimum care necessary to ensure sterilization of non-disposable antiseptic solution containers. A laboratory study was performed with 180 antiseptic containers, which were contaminated with Serratia marcescens [1 x 105 UFC/mL]. The containers were closed and stored, at room temperature, during seven days and shaken daily. The antiseptic cultures were evaluated to be 100% negative to Serratia marcescens in all of the non-disposable containers. These results suggested that antiseptic solutions inactivate microorganisms [1 x 105 UFC/mL]. Since cleaned antiseptic containers have around 102 UFC coming from tap water, it can be inferred that cleansing is a safe minimum procedure to ensure reuse of containers for distribution of CHX and PVP-I solutions in aqueous, detergent and alcoholic formulations.Los objetivos de este estudio fueron evaluar la sobre vivencia de los micro organismos en las diferentes formulaciones de los antisépticos clorexidina (CHX y polivinil-pirrolidona-yodo (PVP-Y, después de una contaminación intencional de los recipientes y extrapolar los resultados de los laboratorios para el cuidado mínimo a ser dispensado a los recipientes de múltiple uso para el envase de los antisépticos probados.

  11. La federazione delle parti. Sul concetto di individuo in Rudolf Virchow

    Directory of Open Access Journals (Sweden)

    Caianiello, Silvia.

    2010-01-01

    Full Text Available An introductory essay to the Italian translation of R. Virchow’s lecture Atome und Individuen, the paper presents his notion of organic individuality as an outcome of his new cell theory. Virchow’s emphasis on the federal structure of the biological individual as composed of “cell-territories” supersedes the previous cellular atomism, and can be considered as a turning point in the establishment of a modular approach to the organism.

    Full Text Available INCOTERMS® do not replace the CISG’s provisions on delivery and the passing of risk in toto, but merely supersede them in so far as they are mutually exclusive. For the rest, they function in tandem. Aspects which are not governed by the INCOTERMS® rules, or inadequately regulated, can be supplemented by the Convention, and vice versa. Collaboration between the two instruments strengthens the unified legal framework for international sales transactions with the view to facilitating international trade.  

  17. [Conscientious objectors among physicians].

    Science.gov (United States)

    Lisker, Rubén; Pérez-Tamayo, Ruy

    2006-01-01

    Conscientious objection refers to the possibility that an individual decides not to comply with a legal mandate because of his or hers convictions, which is accepted by some political constitutions. The classical example is to refuse participation in obligatory military service for personal reasons of conscience, but in the present paper we refer to its use in medical practice utilizing three examples: euthanasia, abortion and the refusal to prescribe emergency contraception. We conclude that in all situations patients rights supersedes conscientious objection.

    Today, a wide variety of techniques is available for the preparation of (semi-) solid, liquid and gaseous samples, prior to their instrumental analysis by means of capillary gas chromatography (GC) or, increasingly, comprehensive two-dimensional GC (GC × GC). In the past two decades, a large number of ‘modern’ sample-preparation techniques has been introduced, which have partly superseded their ‘classical’ counterparts. These novel techniques include off-line and on-line (sometimes semi- or f...

    CERN Document Server

    Boito, Diogo; Jamin, Matthias; Mahdavi, Andisheh; Maltman, Kim; Osborne, James; Peris, Santiago

    2012-01-01

    We review our recent determination of the strong coupling \\alpha_s from the OPAL data for non-strange hadronic tau decays. We find that \\alpha_s(m^2_\\tau) =0.325+-0.018 using fixed-order perturbation theory, and \\alpha_s(m^2_\\tau)=0.347+-0.025 using contour-improved perturbation theory. At present, these values supersede any earlier determinations of the strong coupling from hadronic tau decays, including those from ALEPH data.

    Full Text Available Here we provide a description of the IRT estimation method known as Normal Ogive Harmonic Analysis Robust Method (NOHARM. Although in some ways this method has been superseded by new computer programs that also adopt a specifically factor-analytic approach, its fundamental principles remain useful in certain applications, which include calculating the residual covariance matrix and rescaling the distribution of the common factor (latent trait. These principles can be applied to parameter estimates obtained by any method.

  18. An IoT Knowledge Reengineering Framework for Semantic Knowledge Analytics for BI-Services

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available In a progressive business intelligence (BI environment, IoT knowledge analytics are becoming an increasingly challenging problem because of rapid changes of knowledge context scenarios along with increasing data production scales with business requirements that ultimately transform a working knowledge base into a superseded state. Such a superseded knowledge base lacks adequate knowledge context scenarios, and the semantics, rules, frames, and ontology contents may not meet the latest requirements of contemporary BI-services. Thus, reengineering a superseded knowledge base into a renovated knowledge base system can yield greater business value and is more cost effective and feasible than standardising a new system for the same purpose. Thus, in this work, we propose an IoT knowledge reengineering framework (IKR framework for implementation in a neurofuzzy system to build, organise, and reuse knowledge to provide BI-services to the things (man, machines, places, and processes involved in business through the network of IoT objects. The analysis and discussion show that the IKR framework can be well suited to creating improved anticipation in IoT-driven BI-applications.

    Full Text Available

    I pesci, al momento della pesca, risultano più o meno inquinati in relazione alla qualità delle acque in cui vivono e al tipo di manipolazione che subiscono; tale contaminazione batterica oscilla tra 103ufc/cm2 di superficie corporea e tra 102-109 ufc/gr di intestino. Successivamente, si assiste ad una modificazione quali-quantitativa della microflora iniziale e molti batteri (spoilage flora partecipano attivamente al processo di deterioramento.

    Essenzialmente, la contaminazione microbica del pesce, determina processi proteolitici, sebbene, soprattutto nella fase iniziale, siano i composti azotati non proteici ad essere metabolizzati dai microrganismi. Si formano così composti volatili come trimetilammina, dimetilammina, ammoniaca, che impartiscono odori anomali e associati al deterioramento. Scopo del nostro lavoro è stato quello di quantificare, in campioni di orate (Sparus aurata provenienti da un allevamento di tipo intensivo (impianto a vasche e in quelle provenienti da un allevamento di tipo semintensivo, alcune specie batteriche coinvolte nei processi di deterioramento in condizioni di refrigerazione. Su campioni di pesce appena pescati (conservati e trasportati in ghiaccio, è stata eseguita una cinetica di crescita microbica (tempo 0, 3 e 6 giorni alla temperatura di 4°C su sezioni di pelle e muscolo, visceri e branchie. Sono stati valutati i seguenti parametri microbiologici: conta microbica totale, Pseudomonadaceae, Shewanella putrefaciens ed Enterobacteriaceae totali. Pur partendo da concentrazioni iniziali non significativamente diverse le orate provenienti da allevamento di tipo intensivo hanno evidenziato cariche microbiche più alte (superiori a 107ufc/g a partire dal 3° giorno di conservazione per tutti i parametri considerati.

    Le orate provenienti da allevamento semintensivo sono risultate quindi microbiologicamente più stabili rispetto a quelle provenienti da allevamento intensivo. Pseudomonas fluorescens

Salmonella was identified in two scald water samples but was absent in the water from chiller and in the final product, which might be explained in terms of chlorine addition and temperature reduction. The analysis revealed that MPN of Escherichia coli was in the range of O objetivo deste trabalho foi identificar a contaminação microbiana no processo de escaldagem, assepsia e resfriamento do frango (chiller, e em linguiças de frango produzidas a partir destes. As amostras foram coletadas em um frigorífico de aves, em sete datas e analisadas em triplicata. A presença de Salmonella foi detectada em duas amostras da água de escaldagem não estando mais presente na água do chiller e nem no produto final. Isto se deve à redução de temperatura da água e adição de cloro. O NMP de coliformes fecais variou entre < 1 a 11/ml na água de escaldagem e < 1 a 64/ml na água do chiller, que embora em padrões aceitáveis, mostram tendência de acréscimo no chiller, devido principalmente ao processo de evisceração. As contagens de Aeromonas variaram de 5 a 3,5x10¹UFC/ml na água de escaldagem e 9 a 3,7x10²UFC/ml na água do chiller. Este acréscimo se deve, provavelmente, por Aeromonas ser psicrófila e também devido a retirada das víceras. As análises de linguiça de frango mostraram acréscimo nas contagens de Aeromonas, apresentando até 2,5x10³UFC/g. Esta tendência de aumento de crescimento no produto final, aliado a capacidade de causar infecções de Aeromonas demonstram a necessidade de incluir a análise destas nas avaliações microbiológicas de alimentos.

    Full Text Available El polen apícola es un producto muy nutritivo para el hombre, pero está demostrado que contiene recuentos elevados de bacterias, levaduras y hongos, lo cual constituye un riesgo para la salud humana. Sin embargo, este producto solo es secado entre 40 y 45 ºC antes de su comercialización para el consumo natural. Con el objetivo de comparar la calidad microbiológica del polen apícola fresco y después de secado, fueron realizados ensayos microbiológicos a 28 muestras (400 g cada una de polen apícola fresco y después de secado a 42 ºC, según las Normas NC - ISO 4833:2002, NC - ISO 7954:2002, NC - ISO 6888-1:2003; ISO 7251:2005, ISO 6579:1993, ISO 7937:2004 y NC 38-02-14:1989. Para los indicadores: microbiológicos a 30 ºC, levaduras y hongos, se obtuvo que todas las muestras frescas y secas presentaron recuentos superiores a los límites de aceptabilidad permisibles para este producto (104 UFC · g-1 para el primero y 102 UFC · g-1 para los restantes. No obstante, en el polen seco se detectó un menor número de muestras por indicador con recuentos > 1,5 · 105 UFC · g-1. Los coliformes totales y fecales y Escherichia coli fueron los únicos indicadores que alcanzaron con el secado del polen un descenso en parte de las muestras hasta los límites de aceptación, de 17, 27 y 7 muestras no aceptables en el polen fresco respectivamente, se detectaron en 7, 26 y 4 en el polen seco. Se confirmó la presencia de bacterias patógenas en igual cantidad de muestras frescas y secas, Staphylococcus coagulasa positiva y Salmonella Javiana. Se concluye que el secado, aunque disminuye la microbiota del polen apícola fresco, no es un método efectivo para obtener un producto con calidad microbiológica aceptable.

    As condições higiênicas do ambiente de trabalho e o cumprimento das exigências ofi ciais e legais são fatores importantes na produção e comercialização dos alimentos seguros e de qualidade. A carne por ser um alimento muito perecível, necessita da utilização de métodos de conservação efi cientes e efi cazes, especialmente após o abate do animal. Neste trabalho foram analisadas as condições higiênico-sanitárias de alguns estabelecimentos que comercializam carne bovina, na área metropolitana do município de João Pessoa/PB. Para realização de análises microbiológicas, foram coletadas 10 amostras de carne bovina provenientes de feiras livres e mercados públicos. Os resultados da contagem total de bactérias aeróbias mesófi las variaram de <10 a 1,4x108 UFC/g. Os valores encontrados na determinação do número mais provável de coliformes totais variaram de 2,4x102 a >2,4x103 NMP/g. Os resultados das análises de coliformes fecais encontravam-se entre 9,3x10 e >2,4x103 NMP/g. A presença de Escherichia coli foi confi rmada em seis amostras. Com relação a presença de bolores e leveduras, os valores variaram de <10 a 1,0x106 UFC/g. A contagem de Sthaphylococcus coagulase positivo variou de <10 a 1,8x106 UFC/g. e não foi detectada a presença de Salmonella em nenhuma das amostras. A análise dos resultados sugere que o comércio de carnes em feiras livres e mercados públicos visitados, não atende às exigências da Legislação que regulamenta esse setor.

    Buckingham, R. [OC Robotics, Bristol (United Kingdom)

    2011-07-01

    The condition of primary circuit feeder pipes in CANDU reactors is relevant to the commercial viability and plant life. One known wear mechanism is external fretting between feeder pipes and adjacent services or support structures, particularly within the Upper Feeder Cabinet (UFC). Fretting leads to wall thinning which must not exceed certain agreed limits. Chafe shields have been added to protect the feeder pipes. Regular inspections are required of the chafe shields, feeder pipes and other structures that may cause feeder damage. Historically, the dose received by inspectors conducting this work has been significant. For this reason Ontario Power Generation has invested in a remotely operated robot system to conduct visual inspections within the UFC. This system, called SAFIRE for 'Snake-Arm Feeder Inspection Robot Equipment' has been deployed at Pickering during 2010 and 2011 and has been used to inspect areas that are extremely difficult to inspect with existing manual techniques. The 2011 scope of work included inspection of a total of 660 feeder pipes in three UFC quadrants, in two reactors. The full scope was completed over a one-month period in Autumn 2011 in which SAFIRE was used during 23, twelve hour shifts. This included two periods each of 72 hours of continuous operation using multiple teams of operators. SAFIRE is remote controlled delivery system for multiple cameras to record still images and video. The main system elements include a snake-arm robot mounted on a mobile vehicle. It can be controlled from up to 500m away using a fibre/copper connection. The snake-arm is 2.2m long, 25mm wide and has 18 degrees of freedom. It is designed to snake between the rows of feeder pipes to inspect feeder/hanger interfaces, both above and below the feeder cabinet catwalks. Future upgrades offer the potential to add additional tools to increase functionality. This paper describes the SAFIRE development process from inception to operational experience

    Full Text Available O leite condensado é obtido pela eliminação parcial da água do leite adicionado de sacarose, por meio da evaporação a vácuo. Este processo resulta em um produto com alta concentração de solutos, fator este que previne o crescimento da maioria dos microrganismos. O processo de microcristalização é considerado de fundamental importância para a viscosidade e textura do produto, entretanto pode ser considerado um ponto crítico de controle microbiológico. O uso de embalagens herméticas contribui consideravelmente na manutenção da qualidade do produto enlatado, já que inibe o crescimento de vários microrganismo aeróbios, até mesmo daqueles que são capazes de tolerar uma pressão osmótica alta. Esta é decorrente da adição de açúcar no processo e resulta em redução na atividade de água, afetando a taxa de crescimento e o número de microrganismo da população final. O objetivo deste trabalho foi avaliar, microbiologicamente, 27 amostras de leite condensado, provenientes de três distintos lotes, de nove marcas produzidas em diferentes estados do país, comercializadas no mercado de Juiz de Fora, Minas Gerais. Realizou-se a determinação da contagem padrão em placas (UFC/g, bolores e leveduras (UFC/g, coliformes a 30ºC (NMP/g, coliformes a 45ºC (NMP/g, Staphylococcus sp (UFC/g e Staphylococcus coagulase positiva. Houve altas contagens padrão em placas e de bolores e leveduras, pelas quais pode-se inferir sobre as condições de processamento e armazenamento dos produtos.

    Full Text Available A utilização de métodos moleculares baseados em PCR é fundamental na detecção do Actinobacillus pleuropneumoniae, sendo capaz de identificar a infecção antes do estabelecimento da doença no rebanho. Estes métodos apresentam maior sensibilidade quando comparados com métodos tradicionais de isolamento bacteriano, mas podem sofrer influência de substâncias que reduzem a especificidade do teste e proporcionam o aparecimento de amplificações inespecíficas. No intuito de reduzir as amplificações inespecíficas, observadas quando aplicada a PCR para o gene cpx em amostras de tecido tonsilar, procedeu-se a otimização da técnica, na qual foram analisados o efeito do pré-cultivo bacteriano e as diferentes temperaturas de anelamento dos iniciadores e foi introduzido, no protocolo, um anticorpo que se liga na enzima Taq DNA Polimerase, aumentando a especificidade do teste. Paralelamente, foi realizado um experimento para verificar o efeito inibidor do tecido tonsilar sobre os resultados da PCR. Para isso, porções de tonsila de animais negativos para A. pleuropneumoniae foram contaminadas artificialmente com a amostra referência do sorotipo 5B. A adição do anticorpo para a enzima Taq DNA Polimerase e o aumento da temperatura de anelamento dos iniciadores para 57°C diminuiu o aparecimento de amplificações inespecíficas. Os resultados obtidos no experimento demonstraram que o tecido tonsilar possui efeito inibidor nas amplificações da PCR. Além disso, a amplificação depende de, no mínimo, 675 UFC presentes na alíquota da amostra usada na PCR (equivalente a 1,35 x 10(5 UFC mL-1, assim, amostras de fragmentos de tecido de infecções iniciais e/ou com poucas células podem apresentar resultados falsos negativos.The use of molecular methods based on PCR is important in Actinobacillus pleuropneumoniae detection, being able to identify the infection before the establishment of the disease in the herd.

We found 57 strains of MRSA, and the mecA gene, responsible for resistance, was detected in all of them using a specific molecular probe. We examined 40 strains for the presence of four enterotoxins, after selecting a subset that included all strains from each region, except for the largest sample, from which 10 were randomly selected. Among these two presented enterotoxin B, and growth in human colostrum and trypicase soy broth. After 5 h of incubation at 37°C, population sizes were already higher than 9.4 x 105 UFC/ml and enterotoxin was released into culture medium and colostrum. Our results stress the importance of hygiene, sanitary measures, and appropriate preservation conditions to avoid the proliferation of S. aureus in human milk.

During the heating phase, solar radiation is collected and transferred to the reactor for desorption by a vapor thermal siphon loop. During the cooling phase, heat from the reactor is released to the ambient by a second water vapor loop. Ambient data collected daily during a period of 18 years were divided into hourly values and used to simulate the temperatures of the reactors, which uses salt impregnated with graphite and ammonia, during the adsorption / desorption processes. The results show that the refrigerator operates well in Fortaleza and that better results are expected from the countryside of the state of Ceara. It is concluded that only a high efficiency collector set can be used in the system. (author) 10 refs., 4 figs.; e-mail: eugenia at ufc.br

    Full Text Available In the present work the effects of different brining treatments on mature table olives during natural fermentation were evaluated. The considered olive cultivars are typical of Sicily: Moresca and Giarraffa. They were harvested at pigmented state. The carpological data revealed their good quality as table olives. Natural fermentation was performed with or without acidification up to pH 4, and at 8% and 15% salt concentrations. The physical, chemical and microbiological changes in olives and brines were monitored throughout the processing period. The acidification affected and selected the microbial population and maintained the low pH necessary for the hygienic safety of the product. In fact, in Moresca brines,the lactic acid bacteria totally disappeared after 60 days of fermentation while in Giarraffa they maintained their presence in the brines up to 180 days with a value between 104 UFC/mL and 106 UFC/mL, depending on the salt concentration. The microbial population was also affected by the polyphenol content, which was different between the cultivars. The color of olive fruits was greatly influenced by acidification and less by salt concentration. The addition of salt showed a different influence on the studied cultivars, in fact only the chemical analyses of Giarraffa showed a significant difference between the two levels of salt concentration.

    2016-06-01

    Protein modification by ubiquitin (Ub) and ubiquitin-like (Ubl) proteins plays a pivotal role in a wide range of cellular functions and signaling pathways. The Ufm1 conjugation system is a novel ubiquitin-like system that consists of Ufm1, Uba5 (E1), Ufc1 (E2), and less defined E3 ligase(s) and targets. Despite its discovery more than a decade ago, its biological functions and working mechanism remains poorly understood. Recent genetic studies using knockout mouse models provide unambiguous evidence for the indispensable role of the Ufm1 system in animal development and hematopoiesis, especially erythroid development. In this short review, we summarize the recent progress on this important protein modification system and highlight potential challenges ahead. Further elucidation of the function and working mechanism of the ufmylation pathway would provide insight into disease pathogenesis and novel therapeutic targets for blood-related diseases such as anemia.

Quanto à E. coli, 258 (38,5% dos isolados apresentaram atividade antagonista, sendo todas com inibição parcial. As altas contagens de E. coli e coliformes totais encontradas indicam condições higiênicas inadequadas durante a obtenção do leite. Além disso, a elevada freqüência de BAL com capacidade antagonista a L. monocytogenes, poderia explicar a ausência deste patógeno nas amostras de leite estudadas.

Los resultados revelan un menor porcentaje de muestras positivas para Legionella (19,8% por encima del nivel de 104 UFC/ml BAT establecido como límite de acción, que por debajo de este (80,2%, lo que indica que este limite no cumple su función en las instalaciones investigadas. Niveles de BAT superiores 100 y 1000 UFC/ml parecen ser más útiles para predecir la presencia de Legionella. Hemos observado una concentración de BAT significativamente más elevada en las muestras positivas para Legionella que en las negativas. Esto indica que las BAT son una buena herramienta para la validación de la eficacia del Plan de Autocontol (PA establecido en estas instalaciones. Estos resultados apoyan la importancia de seguir manteniendo el control de las BAT (a 36 ± 1 oC como un indicador de riego de presencia de Legionella y evidencian la necesidad de introducir un límite de acción más bajo para las BAT.

    Pork meat products consumed raw or after a short period of fermentation can be considered at risk for food safety. Sausages (fresh sausage made from pork meat) are produced in several Italian regions, with variation in ingredients. In some Italian Regions, including Abruzzo, these products are frequently consumed raw or undercooked, after a variable period of fermentation. The European Community food regulation promotes the use of challenge tests to determine safety levels. This study is aimed to ensure safety of Abruzzo’s sausages, compared with growth potential (δ) of Listeria monocytogenes and Yersinia enterocolitica, and also aims to define an experimental standard protocol document to carry out challenge tests. Guidelines classify ready-to-eat foods in categories that are able to support (δ>0.5 log10 ufc/g) and not support (δ≤0.5 log10 ufc/g) the growth of Listeria monocytogenes. The products were manufactured according to traditional recipes and were contaminated in laboratory. Results from the experiment yielded information useful to assess the ability of these products to support the growth of pathogenic microorganisms. The batches of sausages were stored at 8, 12, 18 and 20°C to get statistical evaluation. The results showed that, despite the conditioning of the storage temperature and the level of water activity, both organisms remain in the product in concentrations similar to those leading or being able to increase its charge. In particular, the period of greatest consumption of this product (7/8 days of preparation) corresponds to the period of greatest growth of pathogenic microorganisms studied, except for those stored at a temperature of 8°C, which are safer for the consumer.

    Aspergillus is a group of opportunistic fungi that cause infections, with high morbimortality in immunosuppressed patients. Aspergillus fumigatus is the most frequent species in these infections, although the incidence of other species has increased in the last few years. To evaluate the air fungal load and the diversity of Aspergillus species in hospitals with pediatric patients in critical condition. The Intensive Care Unit and Burns Unit of a pediatric hospital were sampled every 15 days during the autumn and spring seasons. The air samples were collected with SAS Super 100(®) and the surface samples were collected by swab method. The UFC/m(3) counts found exceeded the acceptable levels. The UFC/m(3) and the diversity of Aspergillus species found in the Intensive Care Unit were higher than those found in the Burns Unit. The fungal load and the diversity of species within the units were higher than those in control environments. The use of both methods -SAS and swab- allowed the detection of a higher diversity of species, with 96 strains of Aspergillus being isolated and 12 species identified. The outstanding findings were Aspergillus sydowii, Aspergillus niger, Aspergillus flavus, Aspergillus terreus and Aspergillus parasiticus, due to their high frequency. Aspergillus fumigatus, considered unacceptable in indoor environments, was isolated in both units. Aspergillus was present with high frequency in these units. Several species are of interest in public health for being potential pathogenic agents. Air control and monitoring are essential in the prevention of these infections.

    Vegetables intake is widely recommended because of its high content of vitamins, minerals and fiber. However, the irrigation of these vegetables, using wastewaters that have received inadequate treatment often carries unseen microbial pollution that becomes a high risk potential for humans. In the present research, two of the most consumed fresh vegetables cultivated in Mexico City were analyzed, lettuce (Lactuca sativa) and Mexican coriander (Eryngium foetidum). These vegetables are commonly consumed raw. The vegetable choice and the disinfection's method were carried out by the application of two tests to two hundred people in an aleatory form. Similarly, vegetable sampling was carried out by means of a random sampling from the cultivated areas in a chosen "chinampa" (from Náhuatl or Aztec, chinamitl, bulrush or cattail stalks lattice for hydroponics cultivation). Vegetable samples were transferred, in dark plastic bags and in cool boxes at 4 +/- 1.5 degrees C, to the laboratory. Microbiological analysis for Salmonella typhi, mesophilic microorganisms, and fecal coliforms were done according to the "NOM-093SSA1-1994" (Mexico). Results obtained demonstrated that samples treated with the most preferred disinfectant, a colloidal silver based one, had a partial elimination of pathogenic microorganisms found in both vegetables lettuce (Lactuca sativa) and coriander (Eryngium foetidum) samples (mesophyllic microorganisms from 200,000 to 96,500 UFC/g and from 175,000 to 125,000 UFC/g and fecal coliforms from 75 to 0.43 NMP/g and from 150 to 2.10 NMP/g, respectively). Salmonella typhi for all samples gave a positive result. Therefore, it was recommended to the cultivators of the Xochimilco (Náhuatl or Aztec name that means "place where flowers bloom") zone, either stop using contaminated water for irrigation or to use more efficient methods in order to eliminate pathogenic microorganisms, such as diluted chlorine solutions made with commercial cotton clothing bleachers.

    In subclinical Cushing syndrome (SC), it is assumed that glucocorticoid production is insufficient to cause a clinically recognizable syndrome. Differences in hormonal levels or recovery time of the hypothalamic-pituitary-adrenocortical (HPA) axis after adrenalectomy between patients with overt Cushing syndrome (OC) and SC remain unknown. Thirty-six patients (10 with OC and 26 with SC) with adrenal Cushing syndrome who underwent adrenalectomy from 2004 to 2014 were reviewed retrospectively. Patients were treated with glucocorticoid after adrenalectomy and were reevaluated every 1 to 6 months using a rapid adrenocorticotropic hormone (ACTH) stimulation test. Levels of basal 24-hour urine free cortisol (UFC), serum cortisol after an overnight dexamethasone suppression test (DST), and serum cortisol and 24-hour UFC after low-dose DST and high-dose DST were all significantly lower in patients with SC compared with OC. Basal ACTH levels showed significantly higher in patients with SC compared with OC. The probability of recovering adrenal function during follow-up differed significantly between patients with OC and SC (P=0.001), with significant correlations with the degree of preoperative cortisol excess. Patients with OC required a longer duration of glucocorticoid replacement to recover a normal ACTH stimulation test compared with patients with SC (median 17.0 months vs. 4.0 months, P<0.001). The HPA axis recovery time after adrenalectomy in patients with SC is rapid and is dependent on the degree of cortisol excess. More precise definition of SC is necessary to achieve a better management of patients and to avoid the risk of under- or over-treatment of SC patients.

    Hair cortisol evaluation has been used to help detect patients with suspected Cushing syndrome. Our goal was to correlate segmental hair cortisol with biochemical testing in patients with Cushing syndrome and controls. This study was a prospective analysis of hair cortisol in confirmed Cushing syndrome cases over 16 months. Thirty-six subjects (26.5 ± 18.9 years, 75% female, and 75% Caucasian) were analyzed by diurnal serum cortisol, 24 h urinary free cortisol corrected for body surface area (UFC/BSA), and 24 h urinary 17-hydroxysteroids corrected for creatinine (17OHS/Cr). Thirty patients were diagnosed with Cushing syndrome, and six were defined as controls. 3-cm hair samples nearest to the scalp, cut into 1-cm segments (proximal, medial, and distal), were analyzed for cortisol by enzyme immunoassay and measured as pmol cortisol/g dry hair. Hair cortisol levels were compared with laboratory testing done within previous 2 months of the evaluation. Proximal hair cortisol was higher in Cushing syndrome patients (266.6 ± 738.4 pmol/g) than control patients (38.9 ± 25.3 pmol/g) (p = 0.003). Proximal hair cortisol was highest of all segments in 25/36 (69%) patients. Among all subjects, proximal hair cortisol was strongly correlated with UFC/BSA (r = 0.5, p = 0.005), midnight serum cortisol (r = 0.4, p = 0.03), and 17OHS/Cr, which trended towards significance (r = 0.3, p = 0.06). Among the three examined hair segments, proximal hair contained the highest cortisol levels and correlated the most with the initial biochemical tests for Cushing syndrome in our study. Further studies are needed to validate proximal hair cortisol in the diagnostic workup for Cushing syndrome.

    Full Text Available A granelização do leite contribuiu para a diminuição das contagens de bactérias mesófilas no mesmo. Todavia, microrganismos com capacidade de sobreviver em baixas temperaturas, como as bactérias psicrotróficas, passaram a ganhar importância. Estes microrganismos propiciam modificações nos produtos lácteos, interferindo nas suas características sensoriais e reológicas e diminuindo a vida de prateleira. O presente trabalho possuiu como objetivo quantificar microrganismos psicrotróficos em 19 amostras de leite cru provenientes de uma usina beneficiadora da cidade de Uberlândia - MG e analisar a aplicabilidade do método alternativo Compact Dry® TC na enumeração destes microrganismos. Das 19 amostras coletadas, 18 (94,7% apresentaram contagem maior ou igual a 105 UFC.mL-1 e somente em 1 (5,3% amostra a contagem foi inferior a 1,0 x 104 UFC.mL-1, para ambos os métodos. Os resultados evidenciam a necessidade de melhoria nas condições higiênico-sanitárias do manejo e armazenamento desta matéria-prima. A correlação entre os resultados obtidos nos dois métodos de análises utilizados foi positiva e significativa (r2>0,9. Esse coeficiente indica que os dois métodos são equivalentes, e que o Compact Dry® representa uma alternativa para análise de bactérias psicrotróficas.

    Few data are available regarding the need of steroid substitutive therapy after unilateral adrenalectomy for adrenal incidentaloma (AI). It is unknown whether, before surgery, the hypothalamic-pituitary-adrenal (HPA) axis secretion parameters can predict post-surgical hypocortisolism. This study aimed to evaluate whether, in AI patients undergoing unilateral adrenalectomy, post-surgical hypocortisolism could be predicted by the parameters of HPA axis function. Prospective, multicenter. A total of 60 patients underwent surgical removal of AI (surgical indication: 29 subclinical hypercortisolism (SH); 31 AI dimension). Before surgery, SH was diagnosed in patients presenting at least three criteria out of urinary free cortisol (UFC) levels>60 microg/24 h, cortisol after 1-mg dexamethasone suppression test (1 mg-DST)>3.0 microg/dl, ACTH levels5.4 microg/dl. Two months after surgery, HPA axis function was assessed by low dose ACTH stimulation test or insulin tolerance test when needed: 39 patients were affected (Group B) and 21 were not affected (Group A) with hypocortisolism. The accuracy in predicting hypocortisolism of pre-surgical HPA axis parameters or their combinations was evaluated. The presence of >2 alterations among 1 mg-DST>5.0 microg/dl, ACTHhypocortisolism (OR 10.45, 95% confidence interval, CI 2.54-42.95, P=0.001). Post-surgical hypocortisolism was predicted with 100% probability by elevated UFC plus MSC levels, but not ruled out even in the presence of the normality of all HPA axis parameters. Post-surgical hypocortisolism cannot be pre-surgically ruled out. A steroid substitutive therapy is indicated after unilateral adrenalectomy for SH or size of the adenoma.

    Full Text Available Pork meat products consumed raw or after a short period of fermentation can be considered at risk for food safety. Sausages (fresh sausage made from pork meat are produced in several Italian regions, with variation in ingredients. In some Italian Regions, including Abruzzo, these products are frequently consumed raw or undercooked, after a variable period of fermentation. The European Community food regulation promotes the use of challenge tests to determine safety levels. This study is aimed to ensure safety of Abruzzo’s sausages, compared with growth potential (δ of Listeria monocytogenes and Yersinia enterocolitica, and also aims to define an experimental standard protocol document to carry out challenge tests. Guidelines classify ready-to-eat foods in categories that are able to support (δ>0.5 log10 ufc/g and not support (δ≤0.5 log10 ufc/g the growth of Listeria monocytogenes. The products were manufactured according to traditional recipes and were contaminated in laboratory. Results from the experiment yielded information useful to assess the ability of these products to support the growth of pathogenic microorganisms. The batches of sausages were stored at 8, 12, 18 and 20°C to get statistical evaluation. The results showed that, despite the conditioning of the storage temperature and the level of water activity, both organisms remain in the product in concentrations similar to those leading or being able to increase its charge. In particular, the period of greatest consumption of this product (7/8 days of preparation corresponds to the period of greatest growth of pathogenic microorganisms studied, except for those stored at a temperature of 8°C, which are safer for the consumer.

    Serum cortisol concentrations fluctuate in a circadian fashion, and glucocorticoids exert strong effects on adipose tissue and induce obesity through the glucocorticoid receptor. To examine the impact of physiologic levels of circulating cortisol on subcutaneous adipose tissue, 25 overweight and obese subjects were employed, and their serum levels of morning (AM) and evening (PM) cortisol, AM/PM cortisol ratios, and 24-h urinary-free cortisol (UFC) were compared with their clinical parameters, serum cytokine levels, and mRNA expression of 93 receptor action-regulating and 93 glucocorticoid-responsive genes in abdominal subcutaneous fat. AM cortisol levels did not correlate with mRNA expression of the all genes examined, whereas PM cortisol levels, AM/PM cortisol ratios, and 24-h UFC were associated with distinct sets of these genes. Body mass index did not significantly correlate with the four cortisol parameters employed. These results suggest that physiologic levels of AM serum cortisol do not solely represent biological effects of circulating cortisol on the expression of glucocorticoid-related genes in subcutaneous adipose tissue, whereas PM levels, amplitude, and net amounts of the diurnally fluctuating serum cortisol have distinct effects. Through the genes identified in this study, glucocorticoids appear to influence intermediary metabolism, energy balance, inflammation, and local circadian rythmicity in subcutaneous fat. Our results may also explain in part the development of metabolic abnormality and obesity in subjects under stress or patients with melancholic/atypical depression who demonstrate elevated levels of PM serum cortisol.

    Full Text Available A multiplicacão de Staphylococcus aureus e a produção de enterotoxinas estafilocócicas dependem de fatores intrínsecos e da temperatura de armazenamento dos alimentos. O objetivo deste trabalho foi discutir o padrão estafilococos coagulase positiva (ECP para massas alimentícias, estabelecido pela RDC n.º 12 de 2001 da ANVISA, baseando-se nos resultados de atividade de água (a w, potencial hidrogeniônico (pH e contagem de ECP. Cinquenta amostras de 25 tipos de massas de treze marcas diferentes foram analisadas. A contagem de ECP de todas as amostras foi menor que 10 Unidades Formadoras de Colônia por grama (UFC/g, inferior a 5,0 × 10³ UFC/g, estabelecido como limite máximo pela legislação. As médias de a w das massas secas com e sem recheio variaram entre 0,70 e 0,61, respectivamente, o que impossibilita a multiplicação de ECP e produção de toxina. Por outro lado, a média de a w das massas frescas foi de 0,96, o que propicia o desenvolvimento desse padrão microbiológico. Os resultados obtidos neste trabalho indicam que a a w poderia ser utilizada como parâmetro para determinar em quais tipos de massas o padrão ECP deveria ser pesquisado, ou seja, para massas alimentícias cruas que possibilitassem a multiplicação de Staphylococcus spp. (a w > 0,86.

    Full Text Available O setor de Usinagem utiliza fluidos de corte de base vegetal em suas máquinas-ferramenta por serem mais sustentáveis, porém sua composição química os torna mais susceptíveis à degradação. O principal objetivo deste trabalho foi avaliar dois tratamentos para o controle microbiológico em fluidos de corte: extrato vegetal Safeteam (tratamento químico e ultrassom (tratamento físico. De acordo com o histórico de degradação dos fluidos de corte do Centro de Competência em Manufatura (CCM e dados da literatura, identificou-se que o gênero Penicillium sp aparece com maior frequência. Para avaliar a eficiência dos tratamentos, utilizou-se fluido de corte de base vegetal (sem biocida e cepas de Penicillium oxalicum. No primeiro tratamento, utilizou-se a Concentração Mínima Inibitória (CMI de 5% do óleo comercial Safeteam, utilizando o método de profundidade. No segundo tratamento, com ultrassom, utilizou-se 100 mL de amostra de fluido de corte (90% de água e 10% de concentrado para cada parâmetro (variando 2 tempos e 3 potências. Como resultado, o extrato vegetal na CMI de 5% apresentou uma redução de 100% do número de Unidades Formadoras de Colônias (UFCs e o ultrassom uma redução significativa das UFCs, que não foi quantificada, já que, na leitura inicial, a quantidade de colônias foi incontável. Permitindo concluir que ambas as técnicas apresentaram resultados positivos para o controle do bolor Penicillium oxalicum em fluidos de corte.
