    Full Text Available Righteousness through the law and rightousness through faith in Rm 4:13—25: A reaction to EP Sanders In his book Paul and Palestinian Judaism EP Sanders has presented us with a most stimulating approach. His main thesis that traditional New Testament research has misunderstood Paul as well as first century Palestinian Judaism, received positive comment from many quarters. According to Sanders first century Judaism should be understood within a context of gratuity rather than as a religion of works. A survey of Rm 4:13-25 shows, however, that at least Paul viewed righteousness through the law as an entrance requirement in Judaism. As far as the Jewish sources are concerned a preliminary investigation indicates that Sanders' usage and interpretation of these sources are questionable. It seems highly probable that Sanders has misinterpreted Palestinian Judaism and for that reason also Paul's criticism of it.

  8. Pharyngeal odontoma in an adult walleye (Sander vitreus).

    Science.gov (United States)

    Coffee, L L; Bogdanovic, L B; Cushing, T L; Bowser, P R

    2013-05-01

    An adult walleye (Sander vitreus) was submitted to Cornell University for evaluation of a hard pale-tan pharyngeal mass attached to the gill arches. Dozens of hard white conical structures radiated from the surface. Microscopically, conical structures were identified as denticles and rested on plates of dysplastic orthodentine, cementum, and acellular bone. A diagnosis of compound odontoma was made based upon the presence of proliferative epithelial and mesenchymal odontogenic tissues that recapitulated tooth structures normally present on gill rakers. Odontomas are classified as hamartomas and typically develop in immature diphyodont mammals. The pharyngeal location and lifelong regeneration of teeth in fish, however, both qualify the present diagnosis in the pharyngeal region of an adult teleost. Ontogenic and morphologic differences between mammalian and piscine dentition and differentials for tooth-bearing tumors in fish are presented within the context of a developmental anomaly.

    Nemeth, Michael P.

    2014-01-01

    Nonlinear and bifurcation buckling equations for elastic, stiffened, geometrically perfect, right-circular cylindrical, anisotropic shells subjected to combined loads are presented that are based on Sanders' shell theory. Based on these equations, a three-parameter approximate Rayleigh-Ritz solution and a classical solution to the buckling problem are presented for cylinders with simply supported edges. Extensive comparisons of results obtained from these solutions with published results are also presented for a wide range of cylinder constructions. These comparisons include laminated-composite cylinders with a wide variety of shell-wall orthotropies and anisotropies. Numerous results are also given that show the discrepancies between the results obtained by using Donnell's equations and variants of Sanders' equations. For some cases, nondimensional parameters are identified and "master" curves are presented that facilitate the concise representation of results.

    To explore the clinical outcomes of open reduction and internal fixation with calcaneal locking plates in treating Sanders type II and III calcaneal fractures. From January 2010 and October 2012, 38 calcaneal fractures with Sanders type II or III were treated with open reduction and internal fixation with calcaneal locking plate. According to the Sanders classification, 15 fractures were classified as type II, 23 fractures as type III. The patients were divided into two groups (group A and B) according to the different fixed methods. Sustentaculum tali was fixed with one screw in group A, including 13 males and 5 females, with a mean age of (38.56±8.03) years old (ranged, 25 to 55). And sustentaculum tali was not fixed in group B, including 16 males and 4 females, with a mean age of (42.35±8.29) years old (ranged, 29 to 53). Clinical effects were evaluated according to the changes of Böhler's angle and the Maryland Foot Score and VAS score. All patients were followed up from 12 to 20 months with a mean of 14 months. Böhler's angles and subtalar joints obtained satisfactory reconstruction in all patients. One year after operation, the mean Maryland Foot Score was 88.61±7.59 in group A; and was 82.40±9.24 in group B; Maryland Foot Score of group A was higher and foot functional rehabilitation was better than group B. The mean VAS score was 13.39±11.47 in group A; and was 22.50±13.10 in group B; VAS score of group A was lower and foot pain was less than group B. Sustentaculum tall screw fixation has advantages of strong fixed strength, high stability, less postoperative pain, rapid functional recovery in treating Sanders type II and III calcaneal fractures.

    2014-12-01

    Full Text Available Pterocarpus santalinus (Family – Fabaceae popularly known as Red Sanders is an endemic species confined to Southern parts of Eastern Ghats of India specially in Andhra Pradesh. Heartwood of Red Sanders has high demand in domestic as well as international market and the wavy grained wood is valued.  Along with its extensive use in furniture, the red dye obtained from the wood is used as colouring agent for textile, medicine and food. The heartwood can accumulate various elements and rare earth elements like strontium cadmium, zinc, copper and uranium. The wood has different uses in traditional and folklore medicines and is used for the treatment of diabetes, prickly heat, skin diseases and for various other ailments. A number of studies have been carried out to anatomically and phenotypicaly screen wavy grain at seedling stage. Morphological variability and genetic diversity studies reveal that Red Sanders harbours enormous variability. Though, macro and micro propagation protocol have been developed, further refinement is required for mass propagation. Andhra Pradesh Forest Department has also initiated different activities under tree improvement programme. Considering the wood demand, restricted distribution, slow regeneration, illegal harvest, trade and habitat destruction, the species has been categorized as endangered by International Union for Conservation of Nature and has been listed in Convention on International Trade in Endangered Species of Wild Fauna and Flora and is also classified as a “reserved tree” under the Andhra Pradesh Preservation of Private Forest Rules, 1978. To revive the past glory of this valuable species, Government agencies, farmers, entrepreneurs and policy makers have to join hands for its protection, sustainable utilization and conservation.

    2017-01-01

    Full Text Available Background: Calcaneum is the most commonly fractured tarsal bone. The optimal treatment for displaced calcaneus fractures involving the posterior facet is surgical. The extensile lateral approach is commonly preferred because it provides sufficient exposure of the subtalar facet. However, this technique has the risk of complications such as wound necrosis and sural nerve injury. Various minimally invasive approaches, such as sinus tarsi approach, limited posterior approach, and percutaneous approach, have been introduced to reduce possible complications. This study was prospectively performed to evaluate the results of the sinus tarsi approach for Sanders Type 2 calcaneal fractures using postoperative computed tomography (CT. Materials and Methods: Between October 2012 and December 2013, 20 Sanders Type 2 calcaneal fractures were consecutively treated using a sinus tarsi approach and checked using CT preoperatively, immediately postoperatively, and at 12 months after surgery. Clinical evaluations were performed using the visual analog scale (VAS and the ankle-hindfoot score developed by the American Orthopaedic Foot and Ankle Society (AOFAS. Radiographic evaluations were performed using calcaneus lateral and axial radiographs, hindfoot alignment radiograph, and CT. Changes in Böhler's angles and calcaneal widths were evaluated both preoperatively and at last followup. Reduction of the posterior facet was graded according to articular step, defect, and angulation of the posterior facet in CT. Results: VAS and AOFAS scores were significantly improved at 1 year after surgery but did not improve further. Böhler's angles and calcaneal widths were significantly improved after surgery. Böhler's angle was significantly smaller at the last followup than immediately after surgery, whereas calcaneal width was maintained. Reduction of the posterior facet was graded excellent in five feet (25%, good in ten (50%, and fair in five (25% on immediately

    Elevated mercury concentration has been documented in a variety of fish and is a growing concern for human consumption. Here, we explore the influence of physiochemical and watershed attributes on mercury concentration in walleye (Sander vitreus, M.) from natural, glacial lakes in South Dakota. Regression analysis showed that water quality attributes were poor predictors of walleye mercury concentration (R2 = 0.57, p = 0.13). In contrast, models based on watershed features (e.g., lake level changes, watershed slope, agricultural land, wetlands) and local habitat features (i.e., substrate composition, maximum lake depth) explained 81% (p = 0.001) and 80% (p = 0.002) of the variation in walleye mercury concentration. Using an information theoretic approach we evaluated hypotheses related to water quality, physical habitat and watershed features. The best model explaining variation in walleye mercury concentration included local habitat features (Wi = 0.991). These results show that physical habitat and watershed features were better predictors of walleye mercury concentration than water chemistry in glacial lakes of the Northern Great Plains.

    We determined polychlorinated biphenyl (PCB) concentrations in 15 adult female walleyes (Sander vitreus) and 15 adult male walleyes from South Manistique Lake (Michigan, United States), a relatively pristine lake with no point source inputs of PCBs. By measuring PCB concentration in gonads and in somatic tissue of the South Manistique Lake fish, we also estimated the expected change in PCB concentration due to spawning for both sexes. To determine whether gross growth efficiency differed between the sexes, we applied bioenergetics modeling. Results showed that, on average, adult males were 34% higher in PCB concentration than adult females in South Manistique Lake. Results from the PCB determinations of the gonads and somatic tissues revealed that shedding of the gametes led to 1% and 5% increases in PCB concentration for males and females, respectively. Therefore, shedding of the gametes could not explain the higher PCB concentration in adult male walleyes. Bioenergetics modeling results indicated that the sexual difference in PCB concentrations of South Manistique Lake walleyes was attributable, at least in part, to a sexual difference in gross growth efficiency (GGE). Adult female GGE was estimated to be up to 17% greater than adult male GGE.

  4. Localization and seasonal variation of blue pigment (sandercyanin) in walleye (Sander vitreus)

    2015-01-01

    Several fish species, including the walleye (Sander vitreus), have “yellow” and “blue” color morphs. In S. vitreus, one source of the blue color has been identified as a bili-binding protein pigment (sandercyanin), found in surface mucus of the fish. Little is known about the production of the pigment or about its functions. We examined the anatomical localization and seasonal variation of sandercyanin in S. vitreus from a population in McKim Lake, northwestern Ontario, Canada. Skin sections were collected from 20 fish and examined histologically. Mucus was collected from 306 fish over 6 years, and the amount of sandercyanin was quantified spectrophotometrically. Sandercyanin was found solely on dorsal surfaces of the fish and was localized to novel cells in the epidermis, similar in appearance to secretory sacciform cells. Sandercyanin concentrations were significantly higher in fish collected in summer versus other seasons. Yellow and blue morphs did not differ in amounts of sandercyanin, suggesting that the observed blue color, in fact, arises from lack of yellow pigmentation in blue morphs. The function of the sandercyanin remains unclear, but roles in photoprotection and countershading are consistent with available data.

    We used stable isotopes of carbon and nitrogen to evaluate trophic similarity between sauger Sander canadensis and walleye S. vitreus in three Missouri River impoundments characterized by unique differences in riverine habitat. Mean δ15N was similar for sauger and walleye in each reservoir ranging from 15.7 to 17.8‰ for sauger and 15.2 to 17.7‰ for walleye. However, mean δ13C was greater for sauger (−24‰) than for walleye (−25‰) in Lake Oahe (lacustrine habitat), where rainbow smelt Osmerus mordax is an important prey species for walleye. Variation in δ15N and δ13C values was similar between walleye and sauger in Lewis and Clark Lake (riverine habitat), but was greater for sauger than for walleye in Lake Oahe, implying that in pelagic environments, sauger exhibit a larger diet breadth and lower diet consistency compared with walleyes. Isotope analyses support observations from traditional gut content studies that diet overlap between sauger and walleye varies with environmental conditions and is more similar in riverine food webs than in large lakes and impoundments.

    Population genetic relationships reveal the signatures of current processes such as reproductive behaviour and migration, as well as historic events including vicariance and climate change. We analyse population structure of native walleye Sander vitreus across North America, encompassing 10 nuclear DNA microsatellite loci, 26 spawning sites and 921 samples from watersheds across the Great Lakes, Lake Winnipeg, upper Mississippi River, Ohio River and Mobile Bay of the Gulf Coast. Geographical patterning is assessed using phylogenetic trees, pairwise F(ST) analogues, hierarchical partitioning, Mantel regression, Bayesian assignment and Monmonier geographical networks. Results reveal congruent divergences among population groups, corresponding to historic isolation in glacial refugia, dispersal patterns and basin divisions. Broad-scale relationships show genetic isolation with geographical distance, but reproductive groups within basins do not -- with some having pronounced differences. Greatest divergence distinguishes outlying Gulf Coastal and northwest populations, the latter tracing to dispersal from the Missourian refugium to former glacial Lake Agassiz, and basin isolation approximately 7000 ya. Genetic barriers in the Great Lakes separate groups in Lakes Superior, Huron's Georgian Bay, Erie and Ontario, reflecting contributions from Mississippian and Atlantic refugia, and changes in connectivity patterns. Walleye genetic patterns thus reflect vicariance among watersheds and glacial refugia, followed by re-colonization pathways and changing drainage connections that established modern-day northern populations, whose separations are maintained through spawning site fidelity. Conservation management practices should preserve genetic identity and unique characters among these divergent walleye populations.

    The design of surface water quality sampling location is a crucial decision-making process for rationalization of monitoring network. The quantity, quality, and types of available dataset (watershed characteristics and water quality data) may affect the selection of appropriate design methodology. The modified Sanders approach and multivariate statistical techniques [particularly factor analysis (FA)/principal component analysis (PCA)] are well-accepted and widely used techniques for design of sampling locations. However, their performance may vary significantly with quantity, quality, and types of available dataset. In this paper, an attempt has been made to evaluate performance of these techniques by accounting the effect of seasonal variation, under a situation of limited water quality data but extensive watershed characteristics information, as continuous and consistent river water quality data is usually difficult to obtain, whereas watershed information may be made available through application of geospatial techniques. A case study of Kali River, Western Uttar Pradesh, India, is selected for the analysis. The monitoring was carried out at 16 sampling locations. The discrete and diffuse pollution loads at different sampling sites were estimated and accounted using modified Sanders approach, whereas the monitored physical and chemical water quality parameters were utilized as inputs for FA/PCA. The designed optimum number of sampling locations for monsoon and non-monsoon seasons by modified Sanders approach are eight and seven while that for FA/PCA are eleven and nine, respectively. Less variation in the number and locations of designed sampling sites were obtained by both techniques, which shows stability of results. A geospatial analysis has also been carried out to check the significance of designed sampling location with respect to river basin characteristics and land use of the study area. Both methods are equally efficient; however, modified Sanders

    Despite known limitations, Risser staging has traditionally been the primary marker of skeletal maturity utilized in decision-making for treatment of adolescent idiopathic scoliosis (AIS). The purpose of this study is to assess the incidence and factors associated with mismatch between Risser Staging and Sanders classification, and determine interobserver reliability. We reviewed the medical records of consecutive patients aged 10 to 18 referred to our institution for evaluation of AIS from January to June 2016 with a closed triradiate cartilage. Data collected included sex, age, race, height, weight, body mass index percentile, menarchal status, Risser stage, Sanders classification, and major curve. Risser and Sanders stage was determined by 2 fellowship-trained pediatric spine surgeons and 1 pediatric orthopaedic nurse practitioner. Mismatch was defined as Risser stage 2 to 4 corresponding to Sanders 3 to 5, and Risser 0 to 1 corresponding to Sanders 6 to 7. A total of 165 consecutive patients were identified (mean age: 13.9±1.7 y, major curve 28.2±15.4 degrees, 76% female). The risk of skeletal maturity mismatch, based on the criteria of Risser 2 to 5 (limited growth remaining) corresponding to Sanders 3 to 5 (significant growth remaining) was 21.8%, indicating that 1 of 5 patients would be undertreated if managed by Risser criteria. Conversely, the mismatch risk for Risser 0 to 1 corresponding to Sanders 6 to 7 was 3.6%, leading such patients to be treated conservatively longer than necessary. Males and those of Hispanic ethnicity were at a higher risk of mismatch (23.1% vs. 11.9%, P=0.08; 33.3% vs. 8.8%, P=0.04, respectively). Body mass index percentile, race, and major curve were not associated with mismatch. The unweighted and weighted interobserver κ for Risser staging was 0.74 and 0.82, respectively, and 0.86 and 0.91 for Sanders classification, respectively. Given the limited sensitivity of Risser staging during peak growth velocity, high mismatch

    Full Text Available Phthalic acid, di-n-butyl ester known as di-n-butyl phthalate, is an organic chemical compound that belongs to the group of endocrine disruptor compounds that have a documented negative impact on mammalian endocrine systems. Di-n-butyl phthalate is used widely as a plasticizer in the manufacture of artificial materials, which is why it is found in all types of environmental samples including those from water basins. The aim of the study was to describe the impact of di-n-butyl phthalate on the development of the reproductive system of European pikeperch (Sander lucioperca during the sex differentiation period (age 61–96 days post hatch. A total of 240 fish were divided into 6 groups (40 fish per tank. Treatments consisted of a control group (0 g di-n-butyl phthalate·kg-1 feed and five trial groups with 0.125, 0.25, 0.5, 1, and 2 g di-n-butyl phthalate·kg-1 feed, respectively. Histological changes of the fish gonads, sex ratio, survival and growth of fish were evaluated. Di-n-butyl phthalate seriously disturbed sex differentiation process of pikeperch. Histopathological analyses revealed that the administration of 2 g di-n-butyl phthalate·kg-1 significantly affected the sex ratio. The feminization process (intersex gonads at concentrations of 1 g and 2 g di-n-butyl phthalate·kg-1 were observed. All analyzed concentrations delayed testicular development. Phthalate did not have a significant impact on the survival or growth rates of the pikeperch. This is the first report of disruption sex differentiation processes in fish by di-n-butyl phthalate.

  10. Great cormorant (Phalacrocorax carbo predation on pikeperch (Sander lucioperca L. in shallow eutrophic lakes in Poland

    Full Text Available Increases in the population abundance of the piscivorous great cormorant (Phalacrocorax carbo has led to conflicts with fisheries. Cormorants are blamed for decreased fish catches in many lakes in Poland. The aim of this paper is to describe to role of pikeperch (Sander lucioperca in the diet of cormorants nesting in a colony on the island in Lake Warnołty. Since the breeding colony is located in the vicinity of Lake OEniardwy, the largest lake in Poland, the cormorants use the resources in this lake. In 2009-2016, 18,432 regurgitated fish were collected, of which 593 were pikeperch. The share of pikeperch among fish collected in 2009-2012 did not exceed 2%, but from 2013 this increased substantially to maximum of 38.2% in 2015. The smallest pikeperch had a standard length of 8.4 cm, and the largest 42.5 cm. Pikeperch mean length differed by year, and the length distribution was close to normal. The sizes of the regurgitated pikeperch indicate that cormorants prey almost exclusively on juvenile specimens. The results of the present study indicate that cormorant predation has a significant impact on pikeperch populations in lakes in the vicinity of the colony, and the great cormorants are possibly a significant factor in the effectiveness of pikeperch management. When planning for the management of fish populations in lakes subjected to cormorant predation pressure, it should be borne in mind that predation by this piscivorous bird species impacts the abundance and size-age structure of fish populations.

  12. The suitability of Sanders' model for calculation of the propulsive force generated by the hands during sculling motion.

    Gomes, Lara Elena; Boeira, Lucas; Loss, Jefferson Fagundes

    2017-05-01

    This study examined whether Sanders' model is suitable for estimating accurately the propulsive force generated by the hands' motion in swimming comparing the calculated force obtained using the model and the measured force during an actual propulsive action. The measured and calculated forces were obtained from 13 swimmers who, while tethered, performed a sculling motion in a prone position for the purpose of displacing the body by moving it forward. Kinematic analyses were conducted to obtain the calculated force, while the measured force was obtained via the use of a load cell. The calculated force was lower than the measured force and accounted for only a small part of the variation in the measured force. The forces could not be used interchangeably, and there were fixed and proportional differences between them. Consequently, this study indicates that Sanders' model is not suitable for estimating accurately the propulsive force generated by the swimmer's hands during sculling motion. However, research that integrates analyses from different approaches could result in improvements to the model that would render it applicable for estimating the propulsive forces during movements that are characterised by directional changes of the hands.

  15. Naturalizing semiotics: The triadic sign of Charles Sanders Peirce as a systems property.

    The father of pragmatism, Charles Sanders Peirce, gave in 1903 the following definition of a sign: "A Sign, or Representamen, is a First which stands in such a genuine triadic relation to a Second, called its Object, as to be capable of determining a Third, called its Interpretant, to assume the same triadic relation to its Object in which it stands itself to the same Object. The triadic relation is genuine, that is its three members are bound together by it in a way that does not consist in any complexus of dyadic relations". Despite its cult status and its pragmatic foundation, the Peircean sign has never revealed its true potential by being integrated into a formal system. In the present report, a reconstruction of the sign model is presented, which may at first appear somewhat obvious and superficial. However by use of the reconstructed model, the above statement and the majority of Peirce's other statements about the nature of signs fall into place. Instead of defining three links between Object (O), Representamen (R), and Interpretant (I), the sign is described as having a single three-dimensional link, specifying its location in a three dimensional (O,R,I) linkage space. To understand and explain sign function, the process of sign utilization (semiosis) has to be divided into two temporally separated phases, a sign-establishment phase where a three-dimensional link (Ψ(O,R,I)) is formed between three sign elements, and a later sign-interpretation phase where the established linkage is used for inferring significance to a novel phenomenon, if this satisfies the criteria for being a Representamen for the sign. Numerous statements from Peirce indicate that he used a two-staged semiosis paradigm although he did not state that explicitly. The three-dimensional model was primarily constructed for use in biosemiotics, as an exploratory frame for mapping the evolutionary establishment of sign links, which logically must have preceded the fixation of any regulatory

    The effect of ambient salinity changes (0.9, 6 and 12 psu) on the levels of dissolved ammonia (DA), ninhydrin positive substances (NPS), trimethylamine (TMA) and trimethylamine oxide (TMAO) in the blood and tissue of medium-acclimated Sander lucioperca L. (also Stizostedion lucioperca) were investigated. In freshwater, blood and tissue total free amino acid levels (measured as NPS) were 3.62 mM and 60.61 mM, respectively. The NPS content increased significantly (P<0.05) in the tissue and blood on acclimation to 6 and 12 psu salinities. The mass-specific tissue TMAO concentration of pikeperch acclimated to normal freshwater was 0.413+/-0.084 micromol TMAO g(-1). Results reveal that TMAO levels are positively influenced by the external salinity medium where significant differences in mean levels occurred between the groups (P<0.05). The calculated p[NH(3)] and [NH(4)(+)] gradients reveal that the [NH(3)] gradient was consistently low (cf. the [NH(4)(+)] gradient). The gradient of p[NH(3)] decreased with the medium increased salinities. The results suggest that freshwater pikeperch may be able to resist salinity changes by manipulation of nitrogen metabolism. Free amino acids and TMAO are involved in mediating response to salinity exposure in freshwater pikeperch.

    The early development of the postcranial skeleton (pectoral girdle, pelvic girdle, vertebral column and fins) in pikeperch (Sander lucioperca (L.)) was studied from hatching to days 47 and 43 post fertilization (dpf) at two different rearing temperatures, 15.5 and 18.0°C. Four embryonic and six larval stages were described, ranging from 3.4 ± 0.3 mm to 21.8 ± 2.1 mm in total length. The crucial point in larval development is swimbladder inflation, which enables larvae to swim energy efficiently. Until this time point, only the most essential skeletal elements to enable swimming movements have developed. As the larvae become neutrally buoyant, they grow and differentiate postcranial elements rapidly. Concurrently, swimming performance and foraging success seems to improve. A specific size is correlated with a distinct developmental stage defined by a set of traits that includes the skeletal elements. The developmental sequence of skeletal structures is temperature independent, although growth is slower and the individual developmental stages are reached later at 15.5°C than at 18.0°C.

  19. “Let Me Tell You...”: Audience Engagement Strategies in the Campaign Speeches of Trump, Clinton, and Sanders

    Full Text Available Throughout the 2016 campaign, presidential candidate Donald Trump surprised observers with his ability to maintain his popularity in the face of unorthodox and often offensive statements. Trump likely bolstered his electoral chances by appealing to a large segment of voters with whom other candidates failed to align themselves. To quote one news anchor, “People tried to attack Trump; it just didn’t work - voters liked him anyway”. As previous work by Miller (2002; 2004 has shown, systemic functional linguistic (SFL analysis (Halliday & Matthiessen, 2004 can illuminate particular strategies politicians employ to strengthen their arguments and exhort their audiences to join their efforts. In this paper, we employ the SFL-based Engagement framework (White, 2003; Martin & White, 2005 to examine ways in which the 2016 presidential candidates aligned themselves with their audiences. Our analysis of the speeches of Donald Trump, Hillary Clinton, and Bernie Sanders reveals markedly different patterns of interaction with the voters in terms of ways expansive and contractive dialogic strategies are used, an intended audience is identified and thematized, and shared assumptions are made. While Trump makes his arguments in a highly constrained dialogic space, taking the agreement with the audience for granted, his opponents often employ a mix of contractive and expansive argumentative strategies and make more explicit overtures to the audiences whose perspectives they share. This study offers insights as to how each candidate identifies and addresses his or her ideological sympathizers or opponents and exhorts the former to intensify their support.

  20. Effects of clay turbidity and density of pikeperch (Sander lucioperca) larvae on predation by perch (Perca fluviatilis).

    Increased turbidity reduces visibility in the water column, which can negatively affect vision-oriented fish and their ability to detect prey. Young fish could consequently benefit from high turbidity levels that can provide a protective cover, reducing predation pressure. Perch (Perca fluviatilis) are commonly found in littoral zones of temperate lakes and coastal areas of the Baltic Sea. Pikeperch (Sander lucioperca) spawn in these areas, so perch is a potential predator for pikeperch larvae. We conducted laboratory experiments to test the predation of perch on pikeperch larvae at different turbidity levels (5-85 nephelometric turbidity units), densities of pikeperch larvae (2-21 individuals l(-1)) and volumes of water (10-45 l). The logistic regression showed that the probability of larvae eaten depended significantly on turbidity and volume of water in the bags, while density of larvae was not significant. However, because container size is known to affect predation, the data was divided into two groups based on water volume (10-20 and 25-45 l) to reduce the effects of container size. In either group, probability of predation did not significantly depend on volume, whereas turbidity was significant in both groups, while density was significant in larger water volumes. Thus, high turbidity impaired perch predation and protected pikeperch larvae from perch predation. Because density of larvae was also a significant factor affecting predation of perch, the dispersal of pikeperch larvae from spawning areas should also increase the survival of larvae.

  1. Environmental factors regulating the recruitment of walleye Sander vitreus and white bass Morone chrysops in irrigation reservoirs

    Understanding the environmental factors that regulate fish recruitment is essential for effective management of fisheries. Generally, first-year survival, and therefore recruitment, is inherently less consistent in systems with high intra- and interannual variability. Irrigation reservoirs display sporadic patterns of annual drawdown, which can pose a substantial challenge to recruitment of fishes. We developed species-specific models using an 18-year data set compiled from state and federal agencies to investigate variables that regulate the recruitment of walleye Sander vitreus and white bass Morone chrysops in irrigation reservoirs in south-west Nebraska, USA. The candidate model set for walleye included only abiotic variables (water-level elevation, minimum daily air temperature during winter prior to hatching, annual precipitation, spring warming rate and May reservoir discharge), and the candidate model set for white bass included primarily biotic variables (catch per unit effort (CPUE) of black crappie Pomoxis nigromaculatus, CPUE of age-0 walleye, CPUE of bluegill Lepomis macrochirus and CPUE of age-3 and older white bass), each of which had a greater relative importance than the single abiotic variable (minimum daily air temperature during winter after hatching). Our findings improve the understanding of the recruitment of fishes in irrigation reservoirs and the relative roles of abiotic and biotic factors.

    Fidelity to spawning habitats can maximise reproductive success of fish by synchronising movements to sites of previous recruitment. To determine the role of reproductive fidelity in structuring walleye Sander vitreus populations in the Laurentian Great Lakes, we used acoustic telemetry combined with Cormack–Jolly–Seber capture–recapture models to estimate spawning site fidelity and apparent annual survival for the Tittabawassee River in Lake Huron and Maumee River in Lake Erie. Walleye in spawning condition were tagged from the Tittabawassee River in Lake Huron and Maumee River in Lake Erie in 2011–2012. Site fidelity and apparent annual survival were estimated from return of individuals to the stream where tagged. Site fidelity estimates were higher in the Tittabawassee River (95%) than the Maumee River (70%) and were not related to sex or fish length at tagging. Apparent annual survival of walleye tagged in the Tittabawassee did not differ among spawning seasons but was higher for female than male walleye and decreased linearly as fish length increased. Apparent annual survival of walleye tagged in the Maumee River did not differ among spawning seasons but was higher for female walleye than male walleye and increased linearly as fish length increased. Greater fidelity of walleye tagged in the Tittabawassee River than walleye tagged in the Maumee River may be related to the close proximity to the Maumee River of other spawning aggregations and multiple spawning sites in Lake Erie. As spawning site fidelity increases, management actions to conserve population structure require an increasing focus on individual stocks.

    2016-05-01

    Full Text Available Abstract Two types of gonadotropin-releasing hormones (GnRH were identified as gnrh1 and gnrh2 in pikeperch Sander lucioperca. The administration of rodent leptin on hypothalamic organ cultures of immature pikeperch resulted in significantly elevated levels of gnrh2, but not in gnrh1 mRNA, whereas kisspeptin-10 administration did not affect gnrh1 or gnrh2 expression. These results represent preliminary insights into leptin-GnRH-signaling on a hypothalamic level in fish, potentially coupling fat metabolism and the activation of the reproductive axis during puberty. Mammalian leptin and kisspeptin-10, however, failed to initiate a consistent response in pikeperch and their use cannot be recommended.

  8. An assessment of morphometric indices, blood chemistry variables and an energy meter as indicators of the whole body lipid content in Micropterus dolomieu, Sander vitreus and Ictalurus punctatus

    2015-01-01

    The effectiveness of several non-lethal techniques as indicators of total lipid content in smallmouth bass Micropterus dolomieu, walleye Sander vitreus and channel catfish Ictalurus punctatus was investigated. The techniques included (1) the Fulton and relative condition factors, (2) relative mass, (3) plasma indicators of nutritional status (alkaline phosphatase, calcium, cholesterol, protein, triglycerides and glucose) and (4) readings from a hand-held, microwave energy meter. Although simple linear regression analysis showed that lipid content was significantly correlated with several predictor variables in each species, the r2 values for the relations ranged from 0·17 to 0·50 and no single approach was consistent for all species. Only one model, between energy-meter readings and lipid content in I. punctatus, had an r2 value (0·83) high enough to justify using it as a predictive tool. Results indicate that no single variable was an accurate and reliable indicator of whole body lipid content in these fishes, except the energy meter for I. punctatus.

    Determination of the geographic boundaries that define a stock is a key challenge in fisheries management. Acquiring an understanding of spatial distribution and migration patterns of pikeperch Sander lucioperca populations in the south-eastern Baltic Sea region would help to delineate the stocks and contribute towards sustainable exploitation of the population. In this study, habitat use and migratory behaviour of S. lucioperca were inferred from otolith Sr:Ca ratios obtained via an Electron Probe Micro-Analyzer. S. lucioperca collected from the inland Kaunas City water reservoir, where downstream migration is precluded by a hydro-power plant, consistently showed a freshwater signature in their otoliths throughout their life history. In contrast, those collected from the Baltic Sea and Curonian Lagoon in Lithuania, and the lower reaches of the Daugava River in Latvia had ratios indicative of movement between fresh and brackish water habitats. Although S. lucioperca can inhabit brackish water bodies, they predominantly reside and reproduce in freshwater systems. It is thought that periodic post-spawning migration to the sea during spring is related to better foraging conditions and perhaps as a strategy for shedding ectoparasites. Currently, catch quotas apply only to those S. lucioperca taken from the Curonian Lagoon and not the Baltic Sea. Frequent migration between freshwater habitats and the Baltic Sea suggest that S. lucioperca stocks from a given river/estuary system should be considered as a single management unit despite individual differences in migratory behaviour. The extent to which migration into the Baltic Sea could potentially compromise the effectiveness of catch quotas was the main issue which initiated this study.

    Physical processes can generate spatiotemporal heterogeneity in habitat quality for fish and also influence the overlap of pre-recruit individuals (e.g., larvae) with high-quality habitat through hydrodynamic advection. In turn, individuals from different stocks that are produced in different spawning locations or at different times may experience dissimilar habitat conditions, which can underlie within- and among-stock variability in larval growth and survival. While such physically-mediated variation has been shown to be important in driving intra- and inter-annual patterns in recruitment in marine ecosystems, its role in governing larval advection, growth, survival, and recruitment has received less attention in large lake ecosystems such as the Laurentian Great Lakes. Herein, we used a hydrodynamic model linked to a larval walleye (Sander vitreus) individual-based model to explore how the timing and location of larval walleye emergence from several spawning sites in western Lake Erie (Maumee, Sandusky, and Detroit rivers; Ohio reef complex) can influence advection pathways and mixing among these local spawning populations (stocks), and how spatiotemporal variation in thermal habitat can influence stock-specific larval growth. While basin-wide advection patterns were fairly similar during 2011 and 2012, smaller scale advection patterns and the degree of stock mixing varied both within and between years. Additionally, differences in larval growth were evident among stocks and among cohorts within stocks which were attributed to spatiotemporal differences in water temperature. Using these findings, we discuss the value of linked physical–biological models for understanding the recruitment process and addressing fisheries management problems in the world's Great Lakes.

    The aim of this study was to investigate heavy metals and selected minerals contents in filets of pikeperch (Sander lucioperca), carp (Cyprinus carpio) and flathead grey mullet (Mugil cephalus), the major fish species produced in Sidi-Salem reservoir; the largest Tunisian freshwater ecosystem. Concentrations of Ca, Mg, Fe, Zn, Cd, Pb and Hg were determined by inductively coupled plasma-optical emission spectrometry, while concentrations of Na and P were determined by flame photometry and spectrophotometry, respectively. Results concerning heavy metals are considered quantitatively reliable for Hg and Cd but must be taken with precautions concerning Pb levels as the LOD (limit of detection) of the analytical process was higher than acceptable limit. They showed greater accumulations of both Hg and Cd in filets of pikeperch than in filets of carp and mullet, but none of the values exceeded the normative maximum levels (0.500 and 0.050 mg kg -1 w.w., respectively). Considering provisional intakes, target hazard quotient and hazard index, estimated for a fish portion per week, consumption of any of the species did not appear to be potentially hazardous for the health as they were far below threshold values. A fish portion would provide substantial amounts (>15% of daily requirements) in essential mineral nutrients (P, Mg and Fe) and thus should be considered an interesting contribution to a healthy diet. It is strongly advocated to authorities including freshwater fish in the official national annual control survey of contaminants in fishery products, which in addition to guaranteeing security of consumers, would also allow diversifying valorisation opportunities and thus increase the economic value of this fish production.

  20. A population genetic window into the past and future of the walleye Sander vitreus: relation to historic walleye and the extinct “blue pike” S. v. “glaucus”

    Science.gov (United States)

    2014-01-01

    Background Conserving genetic diversity and local adaptations are management priorities for wild populations of exploited species, which increasingly are subject to climate change, habitat loss, and pollution. These constitute growing concerns for the walleye Sander vitreus, an ecologically and economically valuable North American temperate fish with large Laurentian Great Lakes' fisheries. This study compares genetic diversity and divergence patterns across its widespread native range using mitochondrial (mt) DNA control region sequences and nine nuclear DNA microsatellite (μsat) loci, examining historic and contemporary influences. We analyze the genetic and morphological characters of a putative endemic variant– “blue pike” S. v. “glaucus” –described from Lakes Erie and Ontario, which became extinct. Walleye with turquoise-colored mucus also are evaluated, since some have questioned whether these are related to the “blue pike”. Results Walleye populations are distinguished by considerable genetic divergence (mean FST mtDNA = 0.32 ± 0.01, μsat = 0.13 ± 0.00) and substantial diversity across their range (mean heterozygosity mtDNA = 0.53 ± 0.02, μsat = 0.68 ± 0.03). Southern populations markedly differ, possessing unique haplotypes and alleles, especially the Ohio/New River population that houses the oldest haplotype and has the most pronounced divergence. Northern formerly glaciated populations have greatest diversity in Lake Erie (mean heterozygosity mtDNA = 0.79 ± 0.00, μsat = 0.72 ± 0.01). Genetic diversity was much less in the historic Lake Erie samples from 1923–1949 (mean heterozygosity mtDNA = 0.05 ± 0.01, μsat = 0.47 ± 0.06) than today. The historic “blue pike” had no unique haplotypes/alleles and there is no evidence that it comprised a separate taxon from walleye. Turquoise mucus walleye also show no genetic differentiation from other sympatric walleye and

    This study assessed the major histocompatibility complex (MHC) and neutral genetic variation and structure in two percid species, perch Perca fluviatilis and zander Sander lucioperca, in a unique brackish ecosystem, the Baltic Sea. In addition, to assess the importance of MHC diversity to disease susceptibility in these populations, comparisons were made to an introduced, disease susceptible, P. fluviatilis population in Australia. Eighty-three MHC class II B exon 2 variants were amplified: 71 variants from 92 P. fluviatilis samples, and 12 variants from 82 S. lucioperca samples. Microsatellite and MHC data revealed strong spatial genetic structure in S. lucioperca, but not P. fluviatilis, across the Baltic Sea. Both microsatellite and MHC data showed higher levels of genetic diversity in P. fluviatilis from the Baltic Sea compared to Australia, which may have facilitated the spread of an endemic virus, EHNV in the Australian population. The relatively high levels of genetic variation in the Baltic Sea populations, together with spatial genetic structure, however, suggest that there currently seems to be little risk of disease epidemics in this system. To ensure this remains the case in the face of ongoing environmental changes, fisheries and habitat disturbance, the conservation of local-scale genetic variation is recommended. © 2016 The Fisheries Society of the British Isles.

    The purpose of this study was to characterize thermal patterns and generate occupancy models for adult walleye from lakes Erie and Huron with internally implanted biologgers coupled with a telemetry study to assess the effects of sex, fish size, diel periods, and lake. Sex, size, and diel periods had no effect on thermal occupancy of adult walleye in either lake. Thermal occupancy differed between lakes and seasons. Walleye from Lake Erie generally experienced higher temperatures throughout the spring and summer months than did walleye in Lake Huron, due to limnological differences between the lakes. Tagged walleye that remained in Saginaw Bay, Lake Huron (i.e., adjacent to the release location), as opposed to those migrating to the main basin of Lake Huron, experienced higher temperatures, and thus accumulated more thermal units (the amount of temperature units amassed over time) throughout the year. Walleye that migrated toward the southern end of Lake Huron occupied higher temperatures than those that moved toward the north. Consequently, walleye that emigrated from Saginaw Bay experienced thermal environments that were more favorable for growth as they spent more time within their thermal optimas than those that remained in Saginaw Bay. Results presented in this paper provide information on the thermal experience of wild fish in a large lake, and could be used to refine sex- and lake-specific bioenergetics models of walleye in the Great Lakes to enable the testing of ecological hypotheses.

    Chloramine-T (Cl-T) has been used safely and effectively to control bacterial gill disease in salmonids at a maximum exposure regimen of up to four consecutive, once-daily exposures administered for 60??min at 20??mg/L. However, data to document safe treatment concentrations of Cl-T are lacking for freshwater-reared fish other than salmonids. We report the histopathology resultant from the administration of 12 consecutive, once-daily, 180-min static immersion baths of 0, 20, 50, or 80??mg Cl-T/L to walleye (20????C) and channel catfish (27????C). Twelve fish of each species were euthanized immediately before the first exposure (initial controls) and then after the twelfth exposure and 7 and 14??days after the twelfth exposure. Only initial controls and fish euthanized immediately after the twelfth exposure were processed for histological review because of the general lack of exposure-related lesions in exposed fish. The only exposure-related histological changes were in the spleen where significantly greater erythrocyte swelling and necrosis was observed in channel catfish exposed at 80??mg/L relative to exposure at 0??mg/L; similar histological changes were insignificant for walleye, though there appeared to be a shift in the general category of histological change with degenerative changes (necrosis, etc.) observed following exposure at 50 or 80??mg/L compared to the inflammatory and hemodynamic changes (congestion, leukocyte infiltrate, etc.) observed in walleye exposed at 0 or 20??mg/L. The only significant change in peripheral blood cytology was that walleye fingerlings exposed at 80??mg/L had significantly fewer mature red blood cells and significantly more immature red blood cells per oil-immersion field than controls. The histopathological changes observed following exposure to Cl-T under an exaggerated exposure regimen suggest that walleye or channel catfish therapeutically exposed to Cl-T will not have treatment-related histological changes.

  1. The efficacy of scale sampling for monitoring trace element concentrations and stable isotopes in commercially harvested walleye (Sander vitreus).

    Science.gov (United States)

    Ofukany, Amy F A; Hobson, Keith A; Wassenaar, Leonard I; Bond, Alexander L

    2015-01-01

    Commercial and sport fishes are subject to rigorous monitoring for concentrations of elements that could pose threats to human health, with numerous advisories issued by authorities annually for those fisheries with high mercury (Hg) concentrations. In Lake Winnipeg, Manitoba, Canada, the commercial walleye fishery is valued at more than $20 million/year, but has historically been subject to Hg advisories. We used an information theoretic approach to evaluate the utility of non-destructive fish-scale sampling to predict As, Mn and Hg concentrations, as well as stable isotope values in walleye muscle by analysing paired samples. Hg concentrations in scales were significantly related to those in muscle (r(2) = 0.75), but the relationships were weaker for As and Mn. The δ(15)N values in scales predicted δ(15)N in muscle reasonably well (r(2) = 0.72), whereas scale δ(13)C and δ(34)S had less predictive power for estimating their respective muscle stable isotope values. For all three isotope values, sex was a marginal predictor, with parameter confidence intervals bounding zero. Analytical constraints currently limit the utility of non-destructively analysing scales for Hg, but hindcasting trophic changes using archived walleye scales may be useful in understanding shifts in nutrients and production, particularly in impacted lake systems.

    Geologic maps of the western part of the Belt Basin of western Montana and northern Idaho were converted into digital raster (TIFF image) format to facilitate their manipulation in geographic information systems. The 85-mile x 100-mile map area mostly contains rocks belonging to the lower and middle Belt Supergroup. The area is of interest as these Middle Proterozoic strata contain vein-type lead-zinc-silver deposits in the Coeur d?Alene Mining District in the St. Regis and Revett formations and strata-bound copper-silver deposits, such as the Troy mine, within the Revett Formation. The Prichard Formation is also prospective for strata-bound lead-zinc deposits because equivalent Belt strata in southern British Columbia, Canada host the Sullivan lead-zinc deposit. Map data converted to digital images include 13 geological maps at scales ranging from 1:48,000 to 1:12,000. Geologic map images produced from these maps by color scanning were registered to grid tick coverages in a Universal Transverse Mercator (North American Datum of 1927, zone 11) projection using ArcView Image Analysis. Geo-registering errors vary from 10 ft to 114 ft.

    Young-Corbett, Deborah E; Nussbaum, Maury A

    2009-07-01

    In this laboratory study, four drywall sanding tools were evaluated in terms of dust generation rates in the respirable and thoracic size classes. In a repeated measures study design, 16 participants performed simulated drywall finishing tasks with each of four tools: (1) ventilated sander, (2) pole sander, (3) block sander, and (4) wet sponge. Dependent variables of interest were thoracic and respirable breathing zone dust concentrations. Analysis by Friedman's Test revealed that the ventilated drywall sanding tool produced significantly less dust, of both size classes, than did the other three tools. The pole and wet sanders produced significantly less dust of both size classes than did the block sander. The block sander, the most commonly used tool in drywall finishing operations, produced significantly more dust of both size classes than did the other three tools. When compared with the block sander, the other tools offer substantial dust reduction. The ventilated tool reduced respirable concentrations by 88% and thoracic concentrations by 85%. The pole sander reduced respirable concentrations by 58% and thoracic by 50%. The wet sander produced reductions of 60% and 47% in the respirable and thoracic classes, respectively. Wet sponge sanders and pole sanders are effective at reducing breathing-zone dust concentrations; however, based on its superior dust control effectiveness, the ventilated sander is the recommended tool for drywall finishing operations.

    Full Text Available Objective – To determine the success rate of electronic resources for answering clinical questions by comparing speed, validity, and applicability of two different protocols for searching the medical literature.Design – Randomized trial with results judged by blinded panel.Setting – Duke University Medical Center in Durham, North Carolina, United States ofAmerica.Subjects – Thirty‐two 2nd and 3rd year internal medicine residents on an eight week general medicine rotation at the Duke University Medical Center.Methods – Two search protocols were developed:Protocol A: Participants searched MEDLINE first, and then searched pre‐appraised resources if needed.Protocol B: Participants searched pre‐appraised resources first, which included UpToDate, ACP JournalClub, Cochrane Database of Systematic Reviews, and DARE. The residents then searched MEDLINE if an answer could not be found in the 66 initial group of pre‐appraised resources. Residents were randomised by computer-assisted block order into four blocks of eight residents each. Two blocks were assigned to Protocol A, and two to Protocol B. Each day, residents developed at least one clinical question related to caring for patients. The questions were transcribed onto pocket-sized cards, with the answer sought later using the assigned protocol. If answers weren’t found using either protocol, searches were permitted in other available resources. When an article that answered a question was found, the resident recorded basic information about the question and the answer as well as the time required to find the answer (less than five minutes; between five and ten minutes; or more than ten minutes. Residents were to select answers that were “methodologically sound and clinically important” (384. Ten faculty members formally trained in evidence‐based medicine (EBM reviewed a subset of therapy‐related questions and answers. The reviewers, who were blinded to the search protocols, judged the applicability and internal validity of the answers.Results – In total, 120 questions were searched using protocol A and 133 using protocol B; 104 answers were found by the protocol A group and 117 by the protocol B group. In protocol A, 97 answers were found in MEDLINE (80.8% and six answers were found in pre‐appraised resources(5.0%. In protocol B, 85 answers were foundin pre‐appraised resources (64.6% and 31 were found in MEDLINE (23.3%. UpToDate was the major resource for answers in protocol B. A statistically greater number of answers were found in less than five minutes in protocol B (pConclusion – The study demonstrates that to find answers to as many clinical questions as possible, “residents and clinicians need access to both pre-appraised resources and MEDLINE” (385. Pre-appraised resources were faster to search, but their coverage was not as comprehensive. MEDLINE is comprehensive, but takes more time to search effectively and requires that the clinician or student have some knowledge of critical appraisal in order to judge relevance and applicability of found articles. Protocol B may be difficult to implement in many institutions because of the high cost of pre-appraised resources.

  19. Morphology of fractures of the calcaneus in computer tomography scans: Own material analysis

    International Nuclear Information System (INIS)

    Blok, A.; Weiss, W.; Lewandowski, M.

    2005-01-01

    The purpose of this paper is a description of calcaneal fracture morphologies on CT scans, specially intra-articular fractures divided according to the Sanders classification. On the base of this study we conclude that computerized tomography is a good diagnostic method in calcaneal fractures. Analysis of the CT scans showed their specific, repeated morphology. The Sanders classification is very useful in treatment planning and has prognostic value. Computerized tomography was used to evaluate 55 fractures of the calcaneus treated at the Orthopedic and Traumatology Department in Wejherowo from July 2001 to November 2003. For treatment planning, the Sanders classification based on CT was developed. CT scans showed extra-articular fractures of the calcaneus in 5 cases (91%) and intra-articular fractures in 50 cases (91%). According to the Sanders classification, type I was found in 2 cases (4%), type II in 26 cases (47%), type III in 17 cases (31%), and type IV in 5 cases (9%). (author)

  8. Projected impacts of federal tax policy proposals on mortality burden in the United States: A microsimulation analysis.

    Science.gov (United States)

    Kim, Daniel

    2018-06-01

    The public health consequences of federal income tax policies that influence income inequality are not well understood. I aimed to project the impacts on mortality of modifying federal income tax structures based on proposals by two recent United States (U.S.) Presidential candidates: Donald Trump and Senator Bernie Sanders. I performed a microsimulation analysis using the latest U.S. Internal Revenue Service public-use tax file with state identifiers (2008 tax year), containing nationally-representative data from 139,651 tax returns. I considered five tax plan scenarios: 1) actual 2008 tax structures; proposals in 2016 by then-candidates 2) Trump and 3) Sanders; 4) a modified Sanders plan with higher top tax rates (75%); and 5) a modified Sanders plan with higher top rates plus revenue redistribution to lower-income households (<$40,000/year). I combined projected changes in income inequality with vital statistics data and past estimates of linkages between income inequality, income, and mortality. 29,689 (95% CI: 10,865-48,920) more deaths/year and 31,302 (95% CI: 11,455-51,577) fewer deaths/year from all causes are anticipated under the Trump and Sanders plans, respectively. Under the modified Sanders plan including higher top rates, 68,919 (95% CI: 25,221-113,561) fewer deaths/year are projected. Under the modified Sanders plan with redistribution, 333,504 (95% CI: 192,897-473,787) fewer deaths/year are expected. Policies that both raise federal income tax rates and redistribute tax revenue could confer large reductions in the total number of annual deaths among Americans. In this era of high income inequality and growing public support to address the rich-poor gap, policymakers should consider joint federal tax and redistributive policies as levers to reduce the burden of mortality in the United States.

    2002-04-01

    Purpose: We evaluated the reproducibility of three visual scoring methods of emphysema and compared these methods with pulmonary function tests (VC, DLCO, FEV1 and FEV%) among farmer's lung patients and farmers. Material and Methods: Three radiologists examined high-resolution CT images of farmer's lung patients and their matched controls (n=70) for chronic interstitial lung diseases. Intraobserver reproducibility and interobserver variability were assessed for three methods: severity, Sanders' (extent) and Sakai. Pulmonary function tests as spirometry and diffusing capacity were measured. Results: Intraobserver -values for all three methods were good (0.51-0.74). Interobserver varied from 0.35 to 0.72. The Sanders' and the severity methods correlated strongly with pulmonary function tests, especially DLCO and FEV1. Conclusion: The Sanders' method proved to be reliable in evaluating emphysema, in terms of good consistency of interpretation and good correlation with pulmonary function tests.

    Co-occuring conodonts, radiolarians, and sponge spicules from the type locality of the Slaven Chert, northern Shoshone Range, Nevada, indicate that the radiolarian and sponge spicule assemblage described herein correlates with the Late rhenana conodont Zone (late Frasnian). The moderately well preserved radiolarians are the first Frasnian-age fauna described from the Western Hemisphere. They include spumellarians, Ceratoikiscum, and Paleoscenidium, and a radiolarian which we have assigned to a new genus, Durahelenifore Boundy-Sanders and Murchey, with its type species, Durahelenifore robustum Boundy-Sanders and Murchey. Sponge spicules include umbellate microscleres of the Subclass Amphidiscophora, Order Hemidiscosa, previously documented only in Pennsylvanian and younger rocks.

  5. Factors influencing dust exposure: finishing activities in drywall construction.

    Science.gov (United States)

    Simmons, Catherine E; Jones, Rachael M; Boelter, Fred W

    2011-05-01

    Sanding drywall joint compound is a dusty construction activity. We studied potential factors influencing exposure to respirable and total dust for sanders and bystanders in the area of drywall joint compound finishing in 17 test events within a room-scale isolation chamber. We found the air change rate to be negatively correlated with dust C(twa) both in the sander's personal breathing zone and surrounding area. We could not conclude that sanding tool type systematically influences dust C(twa), but the use of 80-grit abrasive was associated with the highest dust C(twa). We found respirable dusts were uniformly dispersed 1-8.2 m from sanding activities at a fixed location. As anticipated, both respirable and total dust C(twa) in the sander's personal breathing zone are higher than in the surrounding area. The respirable fraction of the total dust mass C(twa) was greater in the surrounding area than in the sander's personal breathing zone. Respirable dust concentrations measured in real time increased over the duration of sanding, exhibiting a temporal trend that is similar to that predicted by the well-mixed box model with contaminant removal by mechanical ventilation only, and continuous emission. Dust concentrations returned to pre-activity (background) levels 2-4 hr after cessation of the sanding activity.

  13. Prevalence of Peroneal Tendon Instability in Calcaneus Fractures: A Systematic Review and Meta-Analysis.

    Science.gov (United States)

    Mahmoud, Karim; Mekhaimar, Mohamed Maged; Alhammoud, Abduljabbar

    2018-03-14

    Peroneal tendon instability associated with an intraarticular calcaneal fracture is a common injury that still often passes undiscovered by both radiologists and orthopedic surgeons. Timely identification of this injury will guide the choice of surgical technique used and treatment of patients. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, several databases were searched through June 2017 for any observational or experimental studies that reported the prevalence/incidence of peroneal tendon subluxation/dislocation with a calcaneus fracture with regard to fracture classifications and the significance of the fleck sign. Nine studies were included, with 1027 patients and 1050 calcaneus fractures. The overall prevalence of peroneal instability (PI) in association with a calcaneus fracture was 29.3%. An increasing prevalence of PI increased the severity of the calcaneus fractures, 5.4% in Sanders I, 19% in Sanders II, 39.4% in Sanders III, and 49.5% in Sanders IV. The presence of a fleck sign is a strong indicator of PI, with a prevalence of 54.7%. The computed tomography findings can overestimate the presence of PI compared with the intraoperative findings. The global reported prevalence of peroneal tendon instability associated with intraarticular calcaneal fractures is high and increases with increasing severity of the calcaneus fracture.

    To explore the clinical effects and safty of manipulative reduction with percutaneous poking K-wire fixation for the treatment of the calcaneus fractures and analyze the indication of the minimal invasion. From December 2008 to December 2011,135 closed calcaneal fractures cases were divided randomly into poking group and plate group, treated respectively by percutaneous poking reduction and operative reduction. In poking group, there were 69 cases (82 feet) including 60 males and 9 females, with an average age of (43.29+/-10.46) years ranging from 18 to 64 years; 30 cases of left, 26 cases of right and 13 cases of double; 54 feet of Essex-Lopresti classification tongue form, 28 feet of joint compression; 33 feet of Sanders type II ,49 of type III. In plate group, there were 66 cases (75 feet) including 58 males and 8 females,with an average age of (46.00+/-2.42) years ranging from 21 to 63 years; 31 cases of left, 26 cases of right and 9 cases of double; 48 feet of Essex-Lopresti classification tongue form, 27 feet of joint compression; 28 feet of Sanders type II, 47 of type III. According to Kerr scoring standard,clinical effects and complications were evaluated combining with Sanders and Essex-Lopresti classification. All 135 cases were followed up after 24 weeks. Fractures were recoveried in 8 to 12 weeks (means 10.2 weeks). In poking group, there were 2 cases of infection, 5 cases of wire movement; in plate group,18 cases of wound local skin necrosis, 5 cases of calf intestines nerve injured; there were statistical significant (Pcalcaneus fractures with percutaneous poking and operative redution (P>0.05). In the caes of Sanders type III, there were no significant differences on effects of tongue form fractures with percutaneous poking and operative reduction (P>0.05). There were significant differences on effects and complications of compressing form fractures (Pfractures of Sanders II , III with poking reduction were better than compression fractures. In

  8. Deconstructing cosmology

    Sanders, Robert H

    2016-01-01

    The advent of sensitive high-resolution observations of the cosmic microwave background radiation and their successful interpretation in terms of the standard cosmological model has led to great confidence in this model's reality. The prevailing attitude is that we now understand the Universe and need only work out the details. In this book, Sanders traces the development and successes of Lambda-CDM, and argues that this triumphalism may be premature. The model's two major components, dark energy and dark matter, have the character of the pre-twentieth-century luminiferous aether. While there is astronomical evidence for these hypothetical fluids, their enigmatic properties call into question our assumptions of the universality of locally determined physical law. Sanders explains how modified Newtonian dynamics (MOND) is a significant challenge for cold dark matter. Overall, the message is hopeful: the field of cosmology has not become frozen, and there is much fundamental work ahead for tomorrow's cosmologis...

  9. The importance of symbolic and engaged participation in evidence-based quality improvement in a complex integrated healthcare system: response to "The science of stakeholder engagement in research".

    Science.gov (United States)

    Hamilton, Alison B; Yano, Elizabeth M

    2017-09-01

    In this commentary, we respond to the commentary provided by Goodman and Sanders Thompson regarding our paper on multilevel stakeholder engagement in a VA implementation trial of evidence-based quality improvement (EBQI) in women's health primary care. We clarify our overall approach to engagement (comprised of both symbolic and engaged participation, according to the authors' classification rubric), highlighting that symbolic participation is of more import and value than the authors suggest, especially in the context of a hierarchical healthcare system. We contend that the issue of power-and how power matters in stakeholder engagement-needs to be considered in this context rather than in global "community" terms. In response to the authors' call for greater detail, we clarify our planning processes as well as our approach to veteran engagement. We concur with Goodman and Sanders Thompson that the science of stakeholder engagement necessitates a broader understanding of best practices as well as the impact of engagement on implementation outcomes.

    This study highlights which injury has greatest burden, how frequent are the injuries of foot and ankle areas, which is an extremely neglected specialty in orthopedics and also the importance of proper diagnosis, classification of fractures, appropriate pre-operative planning and timely conservative as well as surgical intervention of ankle and foot fractures that resulted in a satisfactory outcome Despite the fact, foot and ankle is the most important locomotor unit of our lower limb, there have been few studies addressing the problem and treatment outcome of such fractures. Objective: To determine the occurrence, demography and pathomorphology of ankle and foot fractures, also evaluation of treatment outcome of calcaneal fractures. Methodology: This was a longitudinal interventional study which dealt with acute traumatic ankle and foot fracture patients coming to Accident and Emergency Department of MHL, DOST unit 1, with inclusion and exclusion criteria clearly defined. Results: Total 100 patients were included in the study. Mean age of patients was 35.71+-13.60 years. Minimum age of patients was 14 and maximum age of patients was 70 years respectively. Gender distribution of patients shows that 15 patients were female and the remaining 85 patients were male. Male patients were greater in number as compared to female patients ie. M: F, 6:1. Mechanism of the injury showed that there were 48 patients who suffered from RTA , 37 patients had trauma due to fall from height, 6 patients had industrial injuries, 5 patients had Fire Arm Injury, and 2 patients had injuries due to domestic activity, 1 had trauma due to sports activity and 1 had injury due to agricultural work. There were 41 patients with fractures of calcaneum and out of which 5 had bilateral fracture calcaneum. They were classified according to CT based Sanders classification. Out of these 22 patients were of Sanders type III, 12 patients were of Sander type II, 5 patients were of Sander type IV, 2

    was 2.3. Intraoperative scanning led to re-reduction and improvement of reduction in 13 fractures, change of plate position in 1 patient, optimizing of the screw directions in 5 fractures, and shortening of screws that were intra-articular or protruding medially in 6 fractures. The postoperative...... articular displacement was 0 mm in 69% of the Sanders type 2 fractures and 57% of the Sanders type 3 fractures. Operation duration averaged 118 minutes, and there were no reoperations due to misplaced screws or plates. The average absorbed radiation dose per patient was 288 mGy·cm. CONCLUSION......: Intraoperative 3D imaging improved the articular reduction of the posterior facet and secured optimal implant position in displaced calcaneal fractures. Radiation dose to the patient was less than that of a normal foot computed tomography scan. LEVEL OF EVIDENCE: Level IV, case series....

    With Charles Sanders Peirce's semiotical theory two different kinds of creative metaphorical reasoning in science can be identified. The building of remainder metaphors is especially important for creating new scientific models. We show that the conveyor belt metaphor provides an excellent example for Peirce's theory. The conveyor belt metaphor has recently been invented in order to describe the oceanic transport system. The paradigm of the oceanic conveyor belt strongly influenced the geosci...

  9. Free vibration analysis of delaminated composite shells using different shell theories

    International Nuclear Information System (INIS)

    Nanda, Namita; Sahu, S.K.

    2012-01-01

    Free vibration response of laminated composite shells with delamination is presented using the finite element method based on first order shear deformation theory. The shell theory used is the extension of dynamic, shear deformable theory according to the Sanders' first approximation for doubly curved shells, which can be reduced to Love's and Donnell's theories by means of tracers. An eight-noded C 0 continuity, isoparametric quadrilateral element with five degrees of freedom per node is used in the formulation. For modeling the delamination, multipoint constraint algorithm is incorporated in the finite element code. The natural frequencies of the delaminated cylindrical (CYL), spherical (SPH) and hyperbolic paraboloid (HYP) shells are determined by using the above mentioned shell theories, namely Sanders', Love's, and Donnell's. The validity of the present approach is established by comparing the authors' results with those available in the literature. Additional studies on free vibration response of CYL, SPH and HYP shells are conducted to assess the effects of delamination size and number of layers considering all three shell theories. It is shown that shell theories according to Sanders and Love always predict practically identical frequencies. Donnell's theory gives reliable results only for shallow shells. Moreover, the natural frequency is found to be very sensitive to delamination size and number of layers in the shell.

    This study evaluated the clinical and functional outcome of open reduction and internal fixation in intraarticular calcaneal fractures 22 patients with 24 intra-articular fractures of calcaneous were treated, 19 with open reduction and internal fixation using a 3.5 mm AO/ASIF calcaneal plate. The fractures were classified according the Sanders tomographic system. The Bohler angle was measured before and after the surgery. All patients were evaluated using the functional ankle-hind foot AOFAS scale (American Orthopaedics Foot and Ankle Society) 6 and 12 months after the surgery. Mean age was 39.8 years. The distribution according the type of fracture was: Sanders II: 41.67% and Sanders III: 58.33%. The mean value of the initial Bohler angle was 11.45% and the final was 24.5 degrees. The functional outcome after 6 months was 70 points and after 12 months was 82 points. There were only two complications (12.5%) a fistula and a wound dehiscence. The displaced and slightly comminuted intra articular fractures have the calcaneus (Sandres II and Sandres III) benefit of ORIF obtaining good functional outcomes 6 and 12 months after surgery. This procedure allows a better articular surface reduction, a satisfactory Bohler angle correction and earlier rehabilitation

    Percutaneous screw configuration has been used clinically to reduce the high rate of wound complications associated with the extensile approach of standard open reduction and internal plate fixation. The aim of this cadaveric biomechanical study was to compare the strength of the standard perimeter plating with that of the percutaneous screw configuration for a Sanders type-2B calcaneus fracture. Ten pairs of fresh-frozen cadaveric lower limbs were prepared and osteotomized to create a Sanders type-2B fracture. Of each pair, one specimen underwent open reduction and internal fixation with standard perimeter plating; the other was stabilized with the percutaneous screw configuration. Each foot was compressed axially via the talar dome (1 mm/sec) until failure occurred. Differences in treatment groups were analyzed for significance (p plate and percutaneous fixation, respectively (p = 0.18). Failure occurred at an average of 1156 +/- 513 and 1064 +/- 540 N for the plate and percutaneous construct, respectively (p = 0.65). The results suggest that open reduction and internal fixation with percutaneous screw configuration for Sanders type-2B calcaneus fractures provides a strength similar to that of perimeter plating. Percutaneous screw fixation of calcaneus fractures may provide fracture reduction similar to plate fixation.

    To investigate the clinical efficacy of cannulated screw fixation with percutaneous Poking reduction for the treatment of Sanders II, III calcaneal fracture. From January 2012 to January 2014, 19 patients with Sanders II, III calcaneal fracture were treated with cannulated screw fixation with percutaneous Poking reduction. There were 14 males and 5 females, ranging in age from 19 to 58 years old, with an average age of (38.3 +/- 4.1) years old. The changes of Bohler angle and Gissane angle were measured and compared preoperatively and postoperatively to observe the recovery of the articular surface. The Maryland Foot Score was used to evaluate operation outcomes. All the patients were followed up, and the duration ranged from 12 to 28 months with a mean of (22.3 +/- 5.3) months. The Bohler angle and Gissane angle were improved significantly after operation compared with those before operation (P screw fixation with percutaneous Poking reduction has several advantages such as satisfactory outcome,less damage, fewer complications, quicker recovery, and shorter hospital stay,and it is one of the effective treatments for Sanders II and III calcaneal fractures.

    For a fracture classification to be useful it must provide prognostic significance, interobserver reliability, and intraobserver reproducibility. Most studies have found reliability and reproducibility to be poor for fracture classification schemes. The purpose of this study was to evaluate the interobserver and intraobserver reliability of the Sanders and Crosby-Fitzgibbons classification systems, two commonly used methods for classifying intra-articular calcaneal fractures. Twenty-five CT scans of intra-articular calcaneal fractures occurring at one trauma center were reviewed. The CT images were presented to eight observers (two orthopaedic surgery chief residents, two foot and ankle fellows, two fellowship-trained orthopaedic trauma surgeons, and two fellowship-trained foot and ankle surgeons) on two separate occasions 8 weeks apart. On each viewing, observers were asked to classify the fractures according to both the Sanders and Crosby-Fitzgibbons systems. Interobserver reliability and intraobserver reproducibility were assessed with computer-generated kappa statistics (SAS software; SAS Institute Inc., Cary, North Carolina). Total unanimity (eight of eight observers assigned the same fracture classification) was achieved only 24% (six of 25) of the time with the Sanders system and 36% (nine of 25) of the time with the Crosby-Fitzgibbons scheme. Interobserver reliability for the Sanders classification method reached a moderate (kappa = 0.48, 0.50) level of agreement, when the subclasses were included. The agreement level increased but remained in the moderate (kappa = 0.55, 0.55) range when the subclasses were excluded. Interobserver agreement reached a substantial (kappa = 0.63, 0.63) level with the Crosby-Fitzgibbons system. Intraobserver reproducibility was better for both schemes. The Sanders system with subclasses included reached moderate (kappa = 0.57) agreement, while ignoring the subclasses brought agreement into the substantial (kappa = 0.77) range

    The larger foraminifera of the lower part of the Jafnayn Formation outcropping in the Wadi Sayq, in the Paleocene series of the eastern Oman Mountains, have been studied and described in detail. The analysis have allowed us to develop a detailed systematic description of each taxa, constraining their biostratigraphic distribution and defining the associated foraminifera assemblages. The taxonomic study has permitted us to identify each morphotype precisely and describe three new taxa, namely, Ercumentina sayqensis n. gen. n. sp.

    Of growing interest in the control of sediment phosphorus (P) release in lakes is the use of solid phase P-sorbing products (PSPs) including industrial by-products and naturally occurring or modified mineral complexes. However, there is a need to report on novel PSPs proposed by suppliers for use in lake remediation projects at the national scale. We comparatively assessed the elemental composition and P sorption properties of six industrial waste-products (waste-products from treatment of abandoned mine waters - 'red ochre' and 'black ochre'; waste products from building practices: 'gypsum', 'sander dust', 'mag dust' and 'vermiculite') and one commercially available modified lanthanum (La) bentonite product (Phoslock®), all of which have been proposed for use in remediation projects in UK lakes. P sorption was well described (r(2)>0.70) by Langmuir isotherms for all products with the exception of 'gypsum' for which no significant P sorption was reported. P sorption capacities ranged from 4 mgPg(-1) dry weight (d.w.) PSP ('black ochre') to 63 mgg(-1) d.w. ('sander dust'), with products composed mainly of calcium oxide (CaO) and silicon dioxide (SiO(2)) (i.e. 'vermiculite', 'mag dust' and 'sander dust' PSPs) having significantly higher sorption capacities than all other PSPs. Estimates of the equilibrium P concentration (EPC(0)) from Langmuir isotherms indicated that all PSPs, with the exception of 'gypsum', were capable of reducing soluble reactive P (SRP) concentrations to <5.1 μgL(-1). Further research and development required to underpin regulatory policy decisions regarding the use of PSPs is discussed. Dose estimates for each PSP required to treat a eutrophic shallow loch (40.6 ha) with persistent internal loading issues are reported. Copyright © 2012. Published by Elsevier B.V.

    Full Text Available Background: In a retrospective study we analysed intra-articular calcaneal fracture treatment by comparing results and complications related to fracture stabilization with nonlocking calcaneal plates and locking compression plates. Materials and Methods: We performed 76 osteosynthesis (67 patients of intra-articular calcaneal fractures using the standard extended lateral approach from February 2004 to October 2007. Forty-two operations using nonlocking calcaneal plates (group A were performed during the first three years, and 34 calcaneal fractures were stabilized using locking compression plates (group B in 2007. In the Sanders type IV fractures, reconstruction of the calcaneal shape was attempted. Depending on the type of late complication, we performed subtalar arthroscopy in six cases, arthroscopically assisted subtalar distraction bone block arthrodesis in six cases, and plate removal with lateral-wall decompression in five cases. The patients were evaluated by the AOFAS Ankle-Hindfoot Scale. Results: Wound healing complications were 7/42 (17% in group A and 1/34 (3% in group B. No patient had deep osseous infection or foot rebound compartment syndrome. Preoperative size of Bφhler´s angle correlated with postoperative clinical results in both groups. There were no late complications necessitating corrective procedure or arthroscopy until December 2008 in Group B. All late complications ccurred in Group A. The overall results according to the AOFAS Ankle Hindfoot Scale were good or excellent in 23/42 (55% in group A and in 30/34 (85% in group B. Conclusion: Open reduction and internal fixation of intra-articular calcaneal fractures has become a standard surgical method. Fewer complications and better results related to treatment with locking compression plates confirmed in comparison to nonlocking ones were noted for all Sanders types of intra-articular calcaneal fractures.

    There are several published computed tomography (CT) classification systems for calcaneus fractures, each validated by a different standard. The goal of this study was to measure which system would best predict clinical outcomes as measured by a widely used and validated musculoskeletal health status questionnaire. Forty-nine patients with isolated intra-articular joint depression calcaneus fractures more than 2 years after treatment were identified. All had preoperative CT studies and were treated with open reduction and plate fixation using a lateral extensile approach. Four different blinded reviewers classified injuries according to the CT classification systems of Crosby and Fitzgibbons, Eastwood, and Sanders. Functional outcomes evaluated with a Musculoskeletal Functional Assessment (MFA). The mean follow-up was 4.3 years. The mean MFA score was 15.7 (SD = 11.6), which is not significantly different from published values for midfoot injuries, hindfoot injuries, or both, 1 year after injury (mean = 22.1, SD = 18.4). The classification systems of Crosby and Fitzgibbons, Eastwood, and Sanders, the number of fragments of the posterior facet, and payer status were not significantly associated with outcome as determined by the MFA. The Sanders classification trended toward significance. Anterior process comminution and surgeon's overall impression of severity were significantly associated with functional outcome. The amount of anterior process comminution was an important determinant of functional outcome with increasing anterior process comminution significantly associated with worsened functional outcome (P = .04). In addition, the surgeon's overall impression of severity of injury was predictive of functional outcome (P = .02), as determined by MFA. Level III, comparative series. © The Author(s) 2014.

    2002-01-01

    This article outlines the method utilized by physicians and major figures in the founding of Clinical Pastoral Education, Helen Flanders Dunbar, in her work of 1943, Psychosomatic Diagnosis, and relates it to the currently evolving approach in bioethics known as clinical pragmatism. It assesses Dewey's influence on both Dunbar in psychosomatic medicine and clinical pragmatism in bioethics, and illustrates the breadth of influence of the school of philosophical thought known as pragmatism with which Dewey's name and those of William James and Charles Sanders Pierce are most often identified.

The semiotics of Charles Sanders Peirce guided data analysis, regarding to suggested values on the answers of interviewees. The analysis has revealed that, in terms of methodological approaches, Ecology instructors tend to valorize scientific and objective criteria, demonstrating a certain embarrassment on including aesthetic dimension in their teaching, although they recognize the relevance of aesthetic dimension for ethic implications on teaching and for the conservation of natural environment.

    The first professorship in philosophy at Johns Hopkins University was contested in the early 1880s by two of the most prominent and influential scholars in America: Charles Sanders Peirce and George Sylvester Morris. A third figure also vied for the position, although he was much less well known at the time: Granville Stanley Hall. Through a series of unexpected circumstances, Hall ultimately won the professorship and then used it to leverage an extraordinary career that included his opening the first American research laboratory in psychology, establishing the American Journal of Psychology, becoming president of Clark University, founding the American Psychological Association, and profoundly affecting the character of developmental psychology in America.

    Several studies have associated the earlobe crease sign, discovered by Sanders T. Frank in 1973, with cardiovascular pathology, yet very few studies have focused on the antiquity of this trait, with the most ancient one thought to date back to the Roman Emperor Hadrian (76-138CE).

In a Danish bank...... this ‘making-language’, was offered banking customers, who wanted to change their ‘money-behaviour’. They created visual ‘hand-made’ strategies which proved to be strongly self-persuasive: six weeks later the participants had changed their behaviour - and in accordance with their new strategies.

        In conclusion, the article asks where the place of signification or meaning of the exhibited object has moved to in the face of the increased degree of visitor participation. The tentative answer is that the signification generating process has moved away from the historical context of the object and towards the contemporary world of the visitor. The article connects this change in cultural discourse with Karin Sander's archaeological imagination and in a wider sense with the concept of negotiation from new historicism.

    The management of displaced intra-articular calcaneal fractures (DIACFs) remains challenging and controversial. A prospective randomized controlled trial was conducted to compare percutaneous reduction, cannulated screw fixation and calcium sulfate cement (PR+CSC) grafting with minimally invasive sinus tarsi approach and plate fixation (MISTA) for treatment of DIACFs. Ultimately, 80 patients with a DIACFs were randomly allocated to receive either PR+CSC (N = 42) or MISTA (N = 38). Functional outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scores. Radiological results were assessed using plain radiographs and computed tomography (CT) scans, and postoperative wound-related complications were also recorded. The average time from initial injury to operation and the average operation time in the PR+CSC group were both significantly shorter than those in the MISTA group (p < 0.05). There were significantly fewer complications in the PR+CSC group than those in the MISTA group (7.1 % vs 28.9 %, p < 0.001). The calcaneal width immediate postoperatively and at the final follow-up in the MISTA group were obviously improved compared to those in the PR+CSC group (p < 0.001). The variables of sagittal motion and hindfoot motion of the AOFAS scoring system in the PR+CSC group were significantly higher than those in the MISTA group (p < 0.05). The good and excellent results in the two groups were comparable for Sanders Type-II calcaneal fractures, but the good to excellent rate in the MISTA group was significantly higher for Sanders Type-III fractures (p < 0.05). The clinical outcomes are comparable between the two minimally invasive techniques in the treatment of Sanders Type-II DIACFs. The PR+CSC grafting is superior to the MISTA in terms of the average time between initial injury and operation, operation time, wound-related complications and subtalar joint activity. However, the MISTA has its own

    Orthopedic functional devices, are used to improve mandibular length in skeletal class II patients. However, the orthopedic functional device with the best effect to increasing the mandibular length, has not been identified before. Thus, the aim of the present investigation was to evaluate Randomized Controlled Trials (RCT), to determine the best functional appliance improving mandibular length in subjects with retrognathism. A systematic review and meta-analysis was performed, including studies published and indexed in databases between 1966 and 2016. RCTs evaluating functional appliances' effects on mandibular length (Condilion-Gnation (Co-Gn) and Condilion-Pogonion (Co-Po)), were included. Reports' structure was evaluated according to 2010 CONSORT guide. The outcome measure was distance between Co-Gn and/or Co-Po after treatment. Data were analyzed with Cochran Q Test and random effects model. Five studies were included in the meta-analysis. The overall difference in mandibular length was 1.53 mm (Confidence Interval (CI) 95% 1.15-1.92) in comparison to non-treated group. The Sander Bite Jumping reported the greatest increase in mandibular length (3.40 mm; CI 95% 1.69-5.11), followed by Twin Block, Bionator, Harvold Activator and Frankel devices. All removable functional appliances, aiming to increase mandibular length, are useful. Sander Bite Jumping was observed to be the most effective device to improve the mandibular length.

    Full Text Available The objective of this paper is to show how the filmmaker’s genre of choice shapes the main discourse of the film. The author compares Helke Sander’s documentary Liberators Take Liberties (1991-1992 and Max Farberbock’s narrative feature A Woman in Berlin (2008 both dealing with the dramatic effect of the end of WWII, in particular with the instances of German women having been raped by the Allied troops, a theme first publicized in the anonymous diary A Woman in Berlin (1953. There is a clear connection between the book and the two films, but if Sander focuses on the rape itself and on the extraordinary female experience of war, Farberbock is more concerned with cross-national revenge. The author looks closer at the genre elements, particularly at the genres of the diary, the (feminist documentary, and the narrative film. Then, the author draws some parallels between the Helke Sander film and the diary A Woman of Berlin and discusses the documentaries within the feminist framework inspired by Sander’s accomplishments.

    A large volume of wood waste is produced in timber processing industry which traditionally used in low value applications. Here, value addition to the wood waste (Sander dust) and cellulose, hemicellulose isolated thereof by functionalisation using cyclic anhydrides in a solvent-free and green reactive extrusion process is reported. The effect of extrusion temperature, catalyst and different weight ratios of Sander dust (SD):succinic anhydride (SA) on the esterification reaction is evaluated. The esterified products were characterised by the acid value, degree of substitution (DS), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), solid state (13)C NMR and thermo-gravimetric analysis (TGA). Under optimum extrusion conditions, mixed esters are formed, with highest acid value obtained for succinylation of cellulose (0.122 g/g at DS of 0.350) which is two times higher compared to succinylated SD (0.059 g/g at a weight gain of 0.452) and hemicellulose (0.043 g/g at DS of 0.290). The reactivity trend for individual anhydride was: (1) SA-Cellulose>SD>hemicellulose; (2) maleic anhydride (MA)-SD>hemicellulose>cellulose and (3) dodecenyl succinic anhydride (DDSA)-SD ≈ cellulose ≫ hemicellulose. The pendant free carboxyl groups generated through functionalisation of wood waste, cellulose and hemicellulose without the presence of polymeric carriers will allow more tailored or targeted modification of wood-plastic composites.

    2009-06-01

    A telephone survey was conducted to quantify drywall finishing industry usage rates of dust control technology, identify barriers to technology adoption, and explore firm owner perception of risk. Industry use of the following technologies was described: wet methods, respiratory protection, pole sanders, ventilated sanders, and low-dust joint compound. A survey instrument composed of both Likert-type scaled items and open-ended items was developed and administered by telephone to the census population of the owners of member firms of trade associations: Finishing Contractors Association and Association of the Wall and Ceiling Industries. Of 857 firms, 264 interviews were completed. Along with descriptive statistics, results were analyzed to examine effects of firm size and union affiliation on responses. Responses to open-ended items were analyzed using content analysis procedures. Firm owners rated the risk of dust to productivity and customer satisfaction as low-moderate. Half rated the dust as having some impact on worker health, with higher impacts indicated by owners of small firms. Among the available control technologies, respiratory protection was used most frequently. Several barriers to implementation of the more effective control technologies were identified. Barriers associated with technology usability, productivity, and cost, as well as misperceptions of risk, should be addressed to improve dust control in the drywall finishing industry.

Fifty-nine families with a child with ASD aged between 2 and 9 participated in this randomized controlled trial. The results demonstrate significant improvements in parental reports of child behaviour and parenting styles with the treatment effects for child behaviour, parental over reactivity and parental verbosity being maintained at follow-up 6 months later. Further, the results suggest significant improvements in parental satisfaction and conflict about parenting as well as a sleeper effect for parental efficacy. The results indicate that Stepping Stones Triple P is a promising intervention for parents of children with ASD. Limitations and future research are also addressed.

    Aims Identifying predictors of compartment syndrome in the foot after a fracture of the calcaneus may lead to earlier diagnosis and treatment. The aim of our study was to identify any such predictors. Patients and Methods We retrospectively reviewed 303 patients (313 fractures) with a fracture of the calcaneus who presented to us between October 2008 and September 2016. The presence of compartment syndrome and potential predictors were identified by reviewing their medical records. Potential predictors included age, gender, concomitant foot injury, mechanism of injury, fracture classification, time from injury to admission, underlying illness, use of anticoagulant/antiplatelet agents, smoking status and occupation. Associations with predictors were analyzed using logistic regression analysis. Results Of the 313 fractures of the calcaneus, 12 (3.8%) developed a compartment syndrome. A Sanders type IV fracture was the only strongly associated factor (odds ratio 21.67, p = 0.007). Other variables did not reach statistical significance. Conclusion A Sanders type IV fracture is the best predictor of compartment syndrome after a fracture of the calcaneus. Cite this article: Bone Joint J 2018;100-B:303-8.

    Direct visualization of the posterior facet in displaced intra-articular calcaneus fractures (DIACF) frequently shows partial or full thickness cartilage delamination. This is felt to be secondary to the depression of an osteoarticular segment of the posterior facet within the calcaneal body and the subsequent contact with fracture edges as it impacts caudally. The purpose of this study was to determine the frequency of cartilage injury and if it correlates with fracture classification. A single surgeon prospective, observational series of 28 patients with 28 DIACFs was reviewed for patient demographic and injury data, radiographic fracture characterization, and intraoperative observation of articular injury size, depth, and location over the time period of February 2010 to December 2012. Observations were correlated with the OTA and Sanders classification systems. Age, sex, mechanism of injury, and depth and location of cartilage injury were not significantly different between the 13 OTA/Sanders type 2 and 15 type 3 DIACFs evaluated in this study. Posterior facet articular cartilage delamination was found in 77% of type 2 and 100% of type 3 fractures (P = .09). Location of cartilage injury was common (56%) along the distal, lateral aspect of the posterior facet (P fractures (3.1%) then type 2 (1.3%) (P fractures compared to type 2 fractures.

    The radiological and functional results of surgical treatment in intraarticular calcaneal fractures are presented in this study. 27 feet of 26 patients with displaced intraarticular fractures were treated surgically in our clinic between November 2003 and May 2009. Twenty-one patients were male (81%), and 5 were female (19%). The average age was 29.2 (range, 18-61 years) at the time of the surgical treatment. Open reduction internal fixation was performed by using a calcaneal plate. The results were evaluated according to the Maryland foot scores and Creighton-Nebraska scores. The mean follow-up period was 34.4 months (range, 19-85 months). The radiological evaluation was made according to the mean value changes of Böhler and Gissane angles after injury and at the last follow-up. Except for 3 patients with Sanders type 4 fractures, good results were obtained with surgical treatment. We conclude that open reduction and internal fixation methods yield a reasonable outcome, even in patients with Sanders type 4 intraarticular fractures of the calcaneus.

  19. [Biomechanic of the asymmetrical headgear].

    Sander, F G

    1990-11-01

    The asymmetrical headgear is a very useful treatment device for the unilateral distalisation of molars or for the correction of an unilateral anchorage loss. 1. The dimension of the asymmetrical effect depends on the configuration of the outer bows. 2. The function of an asymmetrical face-bow can be increased or decreased by eccentric bendings. 3. According to the geometry at the outer-bows the force at the outer-bow is divided at a different percentage onto the molars. 4. While the forces increase the asymmetrical effect will decrease when the outer-bow is too flexible. 5. Attention has to be payed at each control-appointment to the distance of the longer outer-bow to the cheek. 6. The asymmetrical swivel face-bow did not produce a greater asymmetrical function than other asymmetrical headgears. The reason of this fact is, that only the geometry of the outer-bows is responsible for the unilateral distalisation. 7. The asymmetrical swivel face-bow as described above is advisable to use because eccentric bendings and less forces at the outer-bows will decrease, stop or even reverse the asymmetrical effect. 8. The side-effect of any asymmetrical face-bow is a lateral force-component. This force-component can cause a cross-bite at the molar which has to be more distalized. The molar which is not be moved by the asymmetrical face-bow will be moved buccally by this force-component. 9. The swivel face-bow according to Sander prevents the buccal movement of the molar which should not be moved. But the tendency to create a cross-bite for the molar which should be more distalized, increases. 10. The swivel face-bow according to Sander can be combined with all well-known extraoral tractions. 11. Equal forces at the outer-bows can be reached while using a cervical-pull neckstrap according to Sander. 12. The asymmetrical face-bow and the bite-jumping-appliance can be used simultaneously if the face-bow inserts directly into the attachments of the molar bands.

    Controversy exits over the role of Böhler's angle in assessing the injury severity of displaced intra-articular calcaneal fractures and predicting the functional outcome following internal fixation. This study aims to investigate whether a correlation exists between Böhler's angle and the injury severity of displaced calcaneal fractures, and between surgical improvement of Böhler's angle and functional outcome. Patients treated operatively for unilateral closed displaced intra-articular calcaneal fractures from January 1, 2004 to March 31, 2008 were identified. The Böhler's angles of both calcaneus were measured, and the measurement of the uninjured foot was used as its normal control. The difference in the value of Böhler's angle measured preoperatively or postoperatively between the angle of the injured foot and that of the contralateral calcaneus were calculated, respectively. The change in Böhler's angle by ratio was calculated by dividing the difference value of Böhler's angle between bilateral calcaneus by its normal control. The injury severity was assessed according to Sanders classification. The functional outcomes were assessed using American Orthopaedic Foot & Ankle Society hindfoot scores. 274 patients were included into the study with a mean follow-up duration of 71 months. According to Sanders classification, the fracture pattern included 105 type II, 121 type III and 48 type IV fractures. According to American Orthopaedic Foot & Ankle Society hindfoot scoring system, the excellent, good, fair and poor results were achieved in 104, 132, 27, and 11 patients, respectively. The preoperative Böhler's angle, difference value of Böhler's angle between bilateral calcaneus, and change in Böhler's angle by ratio each has a significant correlation with Sanders classification (rs=-0.178, P=0.003; rs=-0.174, P=0.004; rs=-0.172, P=0.005, respectively), however, is not correlated with functional outcome individually.

    Full Text Available BACKGROUND There are always difference of opinion in the importance of Bohler’s angle in evaluating the severity of displaced intra-articular calcaneal fractures and predicting the functional outcome following surgical fixation. The purpose of this research, the relationship exists between Bohler’s angle and the injury severity of displaced calcaneal fractures and between surgical improvement of Bohler’s angle and its practical outcome. MATERIALS AND METHODS Patients were treated surgically for unilateral closed displaced intra-articular calcaneal fractures from May 2014 to October 2016 were identified. The Bohler’s angles of bilateral calcaneus were measured and was compared to the dimension of the uninjured foot was used as its normal control. The difference in the value of Bohler’s angle measured preoperatively or after surgery between the angle of the damaged foot and that of the contralateral calcaneus was calculated, respectively. The change in Bohler’s angle by ratio was calculated by dividing the variation in the value of Bohler’s angle between bilateral calcaneus by its typical control. The injury severity was assessed according to Sanders classification. The functional outcomes were assessed using American Orthopaedic Foot and Ankle Society hindfoot scores. RESULTS 30 patients were included into the study with a mean follow-up duration of 30 months. According to Sanders classification, the fracture pattern included 12 type II, 10 type III and 8 type IV fractures. According to American Orthopaedic Foot and Ankle Society hindfoot scoring system, the excellent, good, fair and poor results were achieved in 10, 8, 4 and 2 patients, respectively.

    We developed a hinged external fixator for the treatment of dislocated intra-articular calcaneus fractures with severe soft tissue damage. The external fixation was performed with a known external fixator system. The screw insertion points were biomechanically tested by defining a virtual rotation axis through the center of the talus to allow early active motion in the ankle joint. Long-term follow-up was performed after an average of 7.3 years. Results were graded with the American Orthopaedic Foot and Ankle Society (AOFAS) score. Radiographs were reviewed according to Sanders classification. Four open fractures and 33 cases with extremely swollen soft tissue, blisters, or compartment syndromes were treated. In 24 cases (64.9%), the hinged fixator was the final method of treatment (group I). A change to open reduction with internal fixation was performed in 13 fractures (35.1%) when soft tissue problems were minimal (group II). There were no late amputations, osteomyelitis, or malunions. According to Sanders classification, group I consisted of 14 type II, 8 type III, and 2 type IV fractures. Pin loosening or pin infection was seen in 4 cases, but there was no redislocation. The Böhler's angle improved in 43%, gaps in the posterior facet were closed in 41%, and any shortening or deviation of the axis was corrected in 82% of the cases. The AOFAS score for the group averaged 66.5. According to Sanders classification, group II consisted of 8 type II and 5 type III fractures. The Böhler's angle improved in 88%, and gaps in the posterior facet were closed in 87%. Any shortening or deviation of the axis was corrected in 95%, and the AOFAS score averaged 61.3. Significant differences in patient outcome scores between open reduction with internal fixation and hinged fixator were not found. P value was > .05. The hinged external fixator frame can be used in all calcaneus fracture types without soft tissue limitation. The hinged fixator allows early movement in the ankle

    Of the earliest American universities, The Johns Hopkins in Baltimore holds a unique position for psychology. At Hopkins, many of America's first psychologists received their graduate training. Of special interest is the Hopkins Metaphysical Club, organized in 1879 by Charles Sanders Peirce. It provided a forum for research and scholarship by faculty and students. Papers related to topics of the "new" psychology began to appear in 1883, about the time G. Stanley Hall was given a 3-year appointment at Hopkins. When Peirce departed Hopkins in 1885, Hall was free to develop psychology in his image and disbanded the club. Nevertheless, the Metaphysical Club played an important role in the emergence of American scientific psychology.

  9. About signs and symptoms: can semiotics expand the view of clinical medicine?

    Nessa, J

    1996-12-01

    Semiotics, the theory of sign and meaning, may help physicians complement the project of interpreting signs and symptoms into diagnoses. A sign stands for something. We communicate indirectly through signs, and make sense of our world by interpreting signs into meaning. Thus, through association and inference, we transform flowers into love, Othello into jealousy, and chest pain into heart attack. Medical semiotics is part of general semiotics, which means the study of life of signs within society. With special reference to a case story, elements from general semiotics, together with two theoreticians of equal importance, the Swiss linguist Ferdinand de Saussure and the American logician Charles Sanders Peirce, are presented. Two different modes of understanding clinical medicine are contrasted to illustrate the external link between what we believe or suggest, on the one hand, and the external reality on the other hand.

    Paul Ricoeur's hermeneutic phenomenology has proved to be very helpful in guiding nursing researchers' qualitative analysis of interview transcripts. Modifying Ricoeur's philosophy, a number of nursing researchers have developed their own interpretive methods and shared them, along with their experience, with research community. Major contributors who published papers directly presenting their modifications of Ricoeur's theory include Rene Geanellos (2000), Lena Wiklund, Lisbet Lindholm and Unni Å. Lindström (2002), Anders Lindseth and Astrid Norberg (2004) and Pia Sander Dreyer and Birthe D Pedersen (2009). The aim of this article was to delineate differences among these methods. Descriptive presentation of each method side by side makes clear the differences among them. In addition, Ricoeur's hermeneutic theory is portrayed and compared with the modifications. It is believed that differences that are found can stimulate further thoughts on how to apply Ricoeur's theory in qualitative research in nursing. © 2015 John Wiley & Sons Ltd.

  14. Understanding Knowledge through the Example of C. S. Peirce’s Cosmology

    Directory of Open Access Journals (Sweden)

    Enn Kasak

    2016-10-01

    Full Text Available In the era of Charles Sanders Peirce, cosmology was similar to philosophy that was still aspiring to be scientific. Peirce, having worked as an astrophysicist, supported cosmology’s strive towards science. In cosmology, one often relies on knowledge different from everyday knowledge: such knowledge is very general and is situated on the boundaries of what is known; it is very difficult to ascertain it empirically. After Karl Popper, a realist may distinguish between subjective and objective knowledge but this distinction does not suffice for cosmology. A pragmaticist following Peirce could distinguish knowledge about real ideas, which could be termed i-knowledge. This could mean being made party to or being grasped by real ideas functioning outside ourselves. Expressing all i-knowledge as propositional knowledge is difficult. However, non-propositional i-knowledge can sometimes be expressed as principles or paradoxically.

    1999-12-01

    Vapor-liquid equilibrium data of the water + 1,3-propanediol and water + 1,3-propanediol + lithium bromide systems were measured at 60, 160, 300, and 760 mmHg at temperatures ranging from 315 to 488 K. The apparatus used in this work is a modified still especially designed for the measurement of low-pressure VLE, in which both liquid and vapor are continuously recirculated. For the analysis of salt-containing solutions, a method incorporating refractometry and gravimetry was used. From the experimental measurements, the effect of lithium bromide on the VLE behavior of water + 1,3-propanediol was investigated. The experimental data of the salt-free system were successfully correlated using the Wilson, NRTL, and UNIQUAC models. In addition, the extended UNIQUAC model of Sander et al. was applied to the VLE calculation of salt-containing mixtures.

    This article discusses the development and pretesting of key visual imagery in a promotional campaign developed in Quebec, Canada. This campaign is the media-based component of a broader prevention strategy involving the use of the Triple P program (Sanders, 1999). The purpose was to pretest with parents the preliminary version of a poster that uses the campaign's key visual imagery prior to final production. In total, 26 parents from the regions of Quebec City and Montreal participated in four focus groups. Two general themes emerged from the focus groups: (i) emotions and reactions arising from the key visual imagery; and (ii) comprehension of the message being conveyed. Based on this information, recommendations were made to the marketing agency, which then modified the campaign's key visual imagery and proposed a final layout.

Our hypothesis is that the different stages of development of mobile telephony worldwide are reflected in the identity and in the advertising of the brands. We evaluate the brand expressiveness of three countries – Angola, Brazil and Portugal - which represent the different stages mentioned above. The methodological guideline was based on the semiotics of Charles Sanders Peirce (1977 and in the work of Santaella (2000, 2002, Perez (2004 and Lencastre (2007. We identified that the sinsignic environment is determinant in the mobility benefits approached by the brands in its communication, reflecting local changes in the dimensions of space and time with the use of wireless technologies.

  20. Probing the dynamics of elliptical galaxies by planetary nebulae in the framework of MOdified Newtonian Dynamics

    Tian, Yong; Ko, Chung-Ming

    2015-08-01

    Planetary nebulae (PNe) at large distances from the centre of a galaxy provide us a tool to study its dynamics there. Romanowsky et al. (2003) reported the dynamics of three luminous elliptical galaxies up to 6 effective radii, and all of them can be explained by Newtonian dynamics without dark matter. Milgrom & Sanders (2003) deem that the result can be understood in the framework of MOND (MOdified Newtonian dynamics). We revisit this problem as more measurements are available in the past decade. In this contribution, we present our result on 7 elliptical galaxies with PNe data up to 6-8 effective radii and also stellar data from SAURON. We conclude that MOND can well explain the dynamics of all these galaxies.

    The dynamics of an elliptical galaxy within a couple of effective radii can be probed effectively by stars. However, at larger distances planetary nebulae (PNe) replace stars as the tracer of the dynamics. Making use of the motion of PNe, Romanowsky et al. measured the dynamics of three luminous elliptical galaxies (NGC821, NGC3379 and NGC4494) at large distances from the galactic centre. They found that little dark matter is needed up to six effective radii. Milgrom & Sanders showed that this result can be understood in the framework of MOdified Newtonian Dynamics (MOND). As more data are available in the past decade, we revisit this problem. We combine PNe data (up to six to eight effective radii) and stellar data from SAURON of seven elliptical galaxies, including those three galaxies in Romanowsky et al. with updated data and four other galaxies which have not been analysed before. We conclude that the dynamics of these galaxies can be well explained by MOND.

    1989-12-01

    A detailed survey of the carcinological cryptofauna in Tikehau atoll in the Tuamotus, was made: (1) to determine whether Tikehau atoll has a diverse fauna; (2) to compare it with a high island Polynesian reef; (3) to identify the distribution pattern of crabs in relation to depth and to different structures of the atoll; and (4) to compare these results with those obtained in Madagascar, La Réunion and Mauritius. Sixty five species were collected at 13 sites. Cluster analysis based on Sanders' index of affinity revealed one main group of species occurring on outer slopes and another occurring on all reef-flat and lagoonal sites. The crustacean cryptofauna occurring in the atoll appears to be impoverished in comparison to that found on Polynesian high island reefs and on Malagasian reefs. However, all outer reef slope sites at the 3 localities studied share some species in common.

    Full Text Available Sport constitutes an increasingly popular language of discourse in modern societies, providing a (formal system of signs, which is easily used by, among others, businesses, media, public persons, and, particularly willingly, politicians. Thus, sport as a system of meanings can transfer any values, being at the same time a pragmatic way of arguing in the practice of social life. An example we analyze, are the events that took place after Poland (and Ukraine had been chosen to be host countries of UEFA EURO 2012™, as well as those which took place during the tournament itself. In these analyses, we use the concept of semiotics and, in particular, pragmatism as well as Charles Sanders Peirce’s triadic sign relation.

    How do you make a pop-up Big Bang? Well it seems that many of you out there have an opinion on this somewhat esoteric question. When Emma Sanders, co-author of ATLAS’ new pop-up book carried out an informal survey amongst physicists, the question provoked some strong reactions. Paper engineer Anton Radevsky in animated discussion with ATLAS’ Philippe Farthouat and Christoph Rembser. Too spiky: an early version of the pop-up Big Bang."The challenge with the design of every pop-up was to find a solution that both looked good and was scientifically correct," explains Emma. "This was particularly difficult for the Big Bang, where the expansion of the Universe had to be spherically symmetrical and not spiky!" Over 8 pages, the story of ATLAS and the LHC unfolds, pops up, rotates, and, in some cases, readers even have to get hands-on and build elements themselves. Emma worked on the project with...

    2016-01-01

    This book presents diverse topics in mathematical logic such as proof theory, meta-mathematics, and applications of logic to mathematical structures. The collection spans the first 100 years of modern logic and is dedicated to the memory of Irving Anellis, founder of the journal 'Modern Logic', whose academic work was essential in promoting the algebraic tradition of logic, as represented by Charles Sanders Peirce. Anellis’s association with the Russian logic community introduced their school of logic to a wider audience in the USA, Canada and Western Europe. In addition, the collection takes a historical perspective on proof theory and the development of logic and mathematics in Eastern Logic, the Soviet Union and Russia. The book will be of interest to historians and philosophers in logic and mathematics, and the more specialized papers will also appeal to mathematicians and logicians.

    The exposure-related effects of a commercially prepared spray-dried powder (SDP) formulation of Pseudomonas fluorescens, strain CL145A, were evaluated on coldwater, coolwater, and warmwater fish endemic to the Great Lakes and Upper Mississippi River Basins. Nine species of young-of-the-year fish were exposed to SDP for 24 hours by using continuous-flow, serial-dilution exposure systems at temperatures of 12 degrees Celsius (°C; 2 species; Oncorhynchus mykiss [rainbow trout] and Salvelinus fontinalis [brook trout]), 17 °C (3 species; Perca flavescens [yellow perch], Sander vitreus [walleye], and Acipenser fulvescens [lake sturgeon]), or 22 °C (4 species; Micropterus salmoides [largemouth bass], Micropterus dolomieu [smallmouth bass], Lepomis macrochirus [bluegill sunfish], and Ictalurus punctatus [channel catfish]).

    Population availability and vessel avoidance effects on hydroacoustic abundance estimates may be scale dependent; therefore, it is important to evaluate these biases across systems. We performed an inter-ship comparison survey to determine the effect of vessel size, day-night period, depth, and environmental gradients on walleye (Sander vitreus) density estimates in Lake Erie, an intermediate-scaled system. Consistent near-bottom depth distributions coupled with horizontal fish movements relative to vessel paths indicated avoidance behavior contributed to higher walleye densities from smaller vessels in shallow water (i.e., abundance estimates. Quantifying availability and avoidance behavior effects and partitioning sources of variation provides informed flexibility for designing future hydroacoustic surveys in shallow-water nearshore environments.

    Geometrical optical illusions were given this title by Oppel in 1855. Variants on such small distortions of visual space were illustrated thereafter, many of which bear the names of those who first described them. Some original forms of the geometrical optical illusions are shown together with 'perceptual portraits' of those who described them. These include: Roget, Chevreul, Fick, Zöllner, Poggendorff, Hering, Kundt, Delboeuf Mach, Helmholtz, Hermann, von Bezold, Müller-Lyer, Lipps, Thiéry, Wundt, Münsterberg, Ebbinghaus, Titchener, Ponzo, Luckiesh, Sander, Ehrenstein, Gregory, Heard, White, Shepard, and. Lingelbach. The illusions are grouped under the headings of orientation, size, the combination of size and orientation, and contrast. Early theories of illusions, before geometrical optical illusions were so named, are mentioned briefly.

    Full Text Available This article addresses key concepts such as sign, system and complexity in order to approach transmedia storytelling and better understand its intricate nature. The theoretical framework chosen to investigate transmedia storytelling meanders is Semiotics by Charles Sanders Peirce (1839-1914 and General Systems Theory by Mario Bunge (1919-. The complexity of transmedia storytelling is not simply the one of the signs of the works included in a transmedia franchise. It also includes the complexity of the dispositions of users/consumers/players as interpreters of semiotic elements (e.g. characters, themes, environments, events and outcomes presented by transmedia products. It extends further to the complexity of social, cultural, economical and political constructs. The German transmedia narrative The Ultimate SuperHero-Blog by Stefan Gieren and Sofia’s Diary, a Portuguese multiplatform production by BeActive, are presented as examples of closed and open system transmedia storytelling respectively.

    2016-10-01

    In order to evaluate if emotion dysregulation significantly mediates the relationships between childhood abuse and adult attachment and borderline personality disorder features, 354 community Italian adults were administered the Borderline Personality Inventory (Leichsenring, 1999a), the Difficulties in Emotion Regulation Scale (Gratz & Roemer, 2004), the Child Abuse and Trauma Scale (Sanders & Becker-Lausen, 1995), and the Attachment Style Questionnaire (Feeney, Noller, & Hanrahan, 1994). Hierarchical regression analyses showed that both childhood abuse and adult attachment were positively associated with emotion dysregulation and borderline personality features; however, only emotional abuse and the attachment dimension of need for approval were common predictors of both dependent variables. No significant interaction effects were detected in regression analyses. Mediation analyses provided support for partial mediation, revealing a significant mediating role of emotion dysregulation in the relationships between both emotional abuse and need for approval and borderline personality features in this community sample.

    2015-06-01

    Calcaneus fractures are fairly common and clinically relevant due to their poor outcome. Thus, solving the controversy regarding treatment and outcome prediction should be a target. This study intends to evaluate the predictive ability of common radiologic tools for the surgical outcome of calcaneus fractures, regardless of treatment modality. 44 patients' records, with operated calcaneus fractures between 2008 and 2013, were retrospectively assessed and imagiology was blindly evaluated. Patients were submitted to percutaneous or open lateral approach. No relevant correlations were found between the measurements on the plain lateral radiograph and the outcome. Fractures were also graded according to the Sanders classification. Type 4 fractures predicted the occurrence of any hazard, such as skin or pain related complications and need for secondary surgery (p=0.051, odds=14.00 [CI=1.30-150.89]). However, it's still not possible to accurately target patients with high risk of postoperative complications. Until then, follow-up protocols should be maintained indiscriminately.

    2007-05-01

    Full Text Available Charles Sanders Peirce’s creed, “Do Not Block Inquiry,” and his triadic model of the signs serve as the base for a semiotic metatheory of science and scientific theory. Semioticians characterize science as a universe of diverse sign systems, and scientists as members of different language communities.This paper introduces this approach. Affect control theorists ponder and investigate how actors, identities, actions, objects, emotions, and social settings are interrelated during interaction. Semiotic tools and principles guide the translation of the Affect Control Theory(ACT of emotion. ACT is summarized and appraised for its value in increasing our understanding of human behavior in the social environment, its suitability to social work, and its applicability. ACT technical words are translated into simpler language, ACT displays into words, and ACT’s interactionist language is translated into the language of ecosystems theory. Suggestions for strengthening ACT and for promoting semiotic translation are included.

    2014-01-01

    Conserving genetic diversity and local adaptations are management priorities for wild populations of exploited species, which increasingly are subject to climate change, habitat loss, and pollution. These constitute growing concerns for the walleye Sander vitreus, an ecologically and economically valuable North American temperate fish with large Laurentian Great Lakes' fisheries. This study compares genetic diversity and divergence patterns across its widespread native range using mitochondrial (mt) DNA control region sequences and nine nuclear DNA microsatellite (μsat) loci, examining historic and contemporary influences. We analyze the genetic and morphological characters of a putative endemic variant– “blue pike” S. v. “glaucus” –described from Lakes Erie and Ontario, which became extinct. Walleye with turquoise-colored mucus also are evaluated, since some have questioned whether these are related to the “blue pike”.

    Full Text Available Workers in wood industry are exposed to vibration and its damages. The purpose of this study was to evaluate exposure to hand-arm and whole body vibration in the wood industry. In this study, the parameters of whole body and hand-arm vibrations such as effective acceleration, overall equivalent acceleration, Vibration Dose Value and crest factor were studied on two Thicknessing planes, two sliding panel saw machines, two orbital sander, and three operators of perforate procedure. Assessments were done by the use of an oscillator and an analyzer of Svantak Co. Evaluating Hand-arm and whole body vibrations were conducted based on ISO 5349-1, ISO 5349-2 and ISO 2631-1 standards, respectively, and the findings/ the evaluated data were analyzed. The mean amount of daily exposure to hand-arm vibration (RMS in Thicknessing plane, Orbital Sander and Sliding panel saw machine operators are respectively 5.56, 5.49 and 3.37 m/s2 . In addition, the average crest factor of the 3 jobs is higher than 6. Mean of daily Exposure to whole body vibration in 3 machine operators of Thicknessing plane, perforate procedure and Sliding panel saw is respectively, 0.28, 0.24 and 0.17 meters per square second. The crest factor for all the exposures was to be less than 6 and the mean of the calculated daily vibration dose equaled 5.83 with the standard deviation of 0.87( m⁄s^1.75 . In further measured situations, exposure to hand-arm vibration is more than the standard level, so engineering and management measures are required to reduce the amount of exposure and support the health of the operators and the equipment.

One possible explanation is a co-exposure to; wood dust and polycyclic aromatic hydrocarbons (PAHs. PAHs could be generated during incomplete combustion of wood due to heat created by use of power tools.To determine if PAHs are generated from wood during common woodworking operations, PAHs concentrations in wood dust samples collected in an experimental chamber operated under controlled conditions were analyzed. In addition, personal air samples from workers exposed to wood dust (n=30 were collected.Wood dust was generated using tree different power tools: vibrating sander, belt sander, and saw; and six wood materials: fir, Medium Density Fiberboard (MDF, beech, mahogany, oak and wood melamine. Monitoring of wood workers was carried out by means of personnel sampler device during wood working operations. We measured 21 PAHs concentrations in wood dust samples by capillary gas chromatographic-ion trap mass spectrometric analysis (GC-MS.Total PAH concentrations in wood dust varied greatly (0.24 – 7.95 ppm with the lowest being in MDF dust and the highest in wood melamine dust. Personal exposures to PAHs observed were between 37.5-119.8 ng m-3 among workers during wood working operations.Our results suggest that PAH exposures during woodworking operation are present and hence could play a role in the mechanism of cancer induction related to wood dust exposure.

    Initial stability is essential for open reduction internal fixation of intraarticular calcaneal fractures. Geometrical feature of a calcaneal plate is influential to its endurance under physiological load. It is unclear if conventional and pre-contoured anatomical calcaneal plates may exhibit differently in biomechanical perspective. A Sanders' Type II-B intraarticular calcaneal fracture model was reconstructed to evaluate the effectiveness of calcaneal plates using finite element methods. Incremental vertical joint loads up to 450 N were exerted on the subtalar joint to evaluate the stability and safety of the calcaneal plates and bony structure. Results revealed that the anatomical calcaneal plate model had greater average structural stiffness (585.7 N/mm) and lower von Mises stress on the plate (774.5 MPa) compared to those observed in the conventional calcaneal plate model (stiffness: 430.9 N/mm; stress on plate: 867.1 MPa). Although both maximal compressive and maximal tensile stress and strain were lower in the anatomical calcaneal plate group, greater loads on fixation screws were found (average 172.7 MPa compared to 82.18 MPa in the conventional calcaneal plate). It was noted that high magnitude stress concentrations would occur where the bone plate bridges the fracture line on the lateral side of the calcaneus bone. Sufficient fixation strength at the posterolateral calcaneus bone is important for maintaining subtalar joint load after reduction and fixation of a Sanders' Type II-B calcaneal fracture. In addition, geometrical design of a calcaneal plate should worth considering for the mechanical safety in practical usage.

    In Sanders' classification of calcaneus fractures, the medial fracture line (subtype C) is close to the tarsal canal, which contains an artery for the talus and calcaneus. We hypothesized that because of this brittle vascular localization, patients with C line fracture patterns might describe radiologic subtalar arthritis more often and have more complaints. The purpose of the present study was to compare the results of C line fracture patterns with other types of calcaneus fractures. A total of 25 surgically treated feet were involved. Regarding Sanders' classification, group 1 included fractures involving the C line (11 feet), and group 2 included fractures not involving the C line (14 feet). Patient age at admission, trauma date, and interval until surgery were obtained from the patients' medical records. The Bohler angles were determined from the radiographs. At the last follow-up visit, the radiologist graded subtalar arthritis using computed tomography. For clinical follow-up, the American Orthopaedic Foot and Ankle Society and Maryland scores were assessed. No significant differences were found in mean age, follow-up period, delay to surgery, or postoperative Bohler angle between the 2 groups. The mean preoperative Bohler angle was significantly low for group 1. Although not significantly different, the mean American Orthopaedic Foot and Ankle Society and Maryland scores were lower for group 1 (81.9 and 84.3) than group 2 (87.8 and 92.0), and the median subtalar arthritis grade was greater for group 1 (score 2) than for group 2 (score 1.5). The worse results with C line fracture patterns despite satisfactory reduction might result from sinus tarsi artery damage. Angiographic investigations could clarify this theory in the future. Consequently, surgeons must inform and should hesitate to operate on patients with these highly comminuted C line calcaneus fractures. Copyright © 2011 American College of Foot and Ankle Surgeons.

After institutional review board approval, we retrospectively reviewed consecutive CT scans with calcaneal or pilon fractures from 5 years at a level 1 trauma center. We categorized calcaneal fractures according to the Sanders classification, and pilon fractures according to the Ruedi and Allgower and the Arbeitsgemeinschaft fuer Osteosynthesefragen-Orthopaedic Trauma Association (AO-OTA) classifications. Ankle tendons were assessed for dislocation or entrapment. Fisher's exact test was used for statistical analysis with significance at p < 0.05. A total of 312 fractures (91 pilon only, 193 calcaneal only, and 14 ankles with ipsilateral pilon and calcaneal fractures) were identified in 273 patients. Twenty-two pilon, 42 calcaneal, and nine combination fractures were associated with 99 occurrences of tendon entrapment or superior peroneal retinacular injury. Such findings were associated with multiple fractures (p = 0.002). Multifragmentary pilon fractures were associated with posterior tibial and flexor digitorum longus tendon entrapment (p < 0.0001 and p = 0.0003 for Ruedi/Allgower and AO-OTA, respectively), and multifragmentary Sanders type 3 or 4 calcaneal fractures were associated with superior peroneal retinacular injury (p = 0.0473) compared to simple fracture patterns. Thirty-nine percent of tendon entrapments or retinacular injuries were prospectively identified, 85 % by musculoskeletal radiologists (p < 0.0001). Approximately 25 % of calcaneal and pilon fractures were retrospectively identified to contain posteromedial tendon entrapment or superior peroneal retinacular injury. Radiologists should meticulously search for such injuries, particularly when analyzing multifragmentary and multiple fractures. (orig.)

Hosts came from 3 localities in the state of Yucatán, Mexico: Celestún (n= 35, Lagunas de Yalahau (n= 33, and Ría Lagartos (n= 16. Twelve helminth taxa were found: 7 nematodes, 4 digeneans, and 1 acanthocephalan. With the exception of Haematoloechus floedae and Megalodiscus temperatus, all helminth taxa found have a Neotropical distribution. Our results differ from those obtained in previous studies dealing with amphibians in Mexico because we found higher richness and abundance of nematodes than digenean species. The relatively low mean intensity and mean abundance values reached by digenean species in this study may be related to the generalist host diet and with the vagility of frogs (from the aquatic to the terrestrial environment or vice versa.Entre julio del 2004 y junio del 2005, se recolectaron y examinaron 84 ejemplares de Lithobates brownorum (Sanders, 1973 en busca de helmintos en 3 localidades del estado de Yucatán: Celestún (n= 35, Lagunas de Yalahau (n= 33 y Ría Lagartos (n= 16.

Gilman (part one: from Hermann of Mainz to Johannes Pfefferkorn The present paper constitutes the first part of the analysis of Sander L. Gilman’s famous book Jewish Self-Hatred, and the pioneering interpretation of the concept of stereotype. According to Gilman, a stereotype emerges as a result of an active collaboration of the person who stereotypises and the outsider. The latter opposes the image imposed by the stereotype, and thus splits the stereotype into a positive and a negative part. By identifying himself with the positive part, the outsider delegates the purity of classification not only to the subgroup he does not feel any attachment to, but also involuntarily legitimises the stereotype, because without his authorisation, the stereotype would merely remain a racist insult. The article is based on the narrations of Jewish converts to Christianity from the Middle Ages to the 15th century.   Hassliebe. Żydowska samonienawiść w ujęciu Sandera L.

    The Apuseni mountains in Romania take a central position in the Alpine Carpathian Dinaride system and separate the Pannonian basin in the west from the Transsylvanian basin in the east. The Cretaceous age nappe stack involves from bottom to top Tisza- (Bihor and Codru) and Dacia-derived units (Biharia, according to Schmid et al., 2008) overlain by the South Apuseni and Transylvanian ophiolite belt. This study tries to provide new and additional information on the structural and metamorphic evolution of these units from the Jurassic obduction to neotectonic activity. This also comprises information on their interaction with the neighbouring basins. The objective is to show the impact of large scale (plate) tectonics (f.i. in terms of its thermal configuration and strengths profile) and the impact of early-formed tectonic features for the further evolution, specifically the formation of the surrounding basins together with its feedback with topography. This approach includes investigation of kinematics along first order contacts during distinct events together with the thermotectonic characterization of the involved units. While the early "high-grade" evolution will be geochronologically addressed by Sm/Nd, Rb/Sr and Ar/Ar dating, fission track analysis on zircon and apatite will be used to constrain the low-temperature part of the story. Already available data by Sanders (1998), Schuller (2004), Merten (in preparation) and Kounov (in preparation) together with new own data will be used to provide a 4D model for the late-stage thermal evolution of the Apuseni mountains. Thermal modelling will be compared and integrated with numerical modelling of the landscape evolution. The hereby generated data and information on erosion and exhumation will be further used in associated partner projects of the Source to Sink research network which addresses the evolution of the Danube system from the hinterland to the Black Sea.

    Increasing production and applications of manufactured nano objects (MNOs) have become a source for human exposure and therefore raise concerns and questions about the possible health effects. In this study, the potential release of nano objects, their agglomerates, and aggregates (NOAA) as a result of sanding of hardwood treated with MNOs-containing coating was examined. Two types of MNO-containing coating were compared with untreated hardwood that allowed the evaluation of the influence of the chemical composition on the release of particles. Furthermore, the rotation speed of the sander and the grit size of the sanding paper were varied in order to assess their influence on the release of particles.Measurements were conducted in a gas-tight chamber with a volume of 19.5 m(3) in which ventilation was minimized during experiments. Particle size distributions were assessed by scanning mobility particle sizer , aerodynamic particle sizer, and electrical low pressure impactor. Furthermore, aerosol number concentrations (Nanotracer), active surface area (LQ1), and fractionated mass (Cascade Impactor) were measured before, during, and after sanding. Scanning electron microscope/energy dispersive X-ray (SEM/EDX) analysis was performed to adequately characterize the morphology, size, and chemical composition of released particles.SEM/EDX analysis indicated that sanding surfaces treated with MNO-containing coating did not release the designated MNO as free primary particles. In both coatings, clusters of MNO were perceived embedded in and attached to micro-sized wood and/or coating particles created by sanding the coated surface. Real-time measurements indicated a lower release of micro-sized particles from sanding of surfaces treated with Coating I than from sanding untreated surfaces or surfaces treated with Coating II. A substantial increase in nanosized and a slight increase in micro-sized particles was perceived as the rotation speed of the sander increased. However

    Urban flood risk is influenced by many factors such as hydro-meteorological drivers, existing drainage systems as well as vulnerability of population and assets. The urban fabric itself has also a complex influence on inundation flows. In this research, we performed a systematic analysis on how various characteristics of urban patterns control inundation flow within the urban area and upstream of it. An urban generator tool was used to generate over 2,250 synthetic urban networks of 1 km2. This tool is based on the procedural modelling presented by Parish and Müller (2001) which was adapted to generate a broader variety of urban networks. Nine input parameters were used to control the urban geometry. Three of them define the average length, orientation and curvature of the streets. Two orthogonal major roads, for which the width constitutes the fourth input parameter, work as constraints to generate the urban network. The width of secondary streets is given by the fifth input parameter. Each parcel generated by the street network based on a parcel mean area parameter can be either a park or a building parcel depending on the park ratio parameter. Three setback parameters constraint the exact location of the building whithin a building parcel. For each of synthetic urban network, detailed two-dimensional inundation maps were computed with a hydraulic model. The computational efficiency was enhanced by means of a porosity model. This enables the use of a coarser computational grid , while preserving information on the detailed geometry of the urban network (Sanders et al. 2008). These porosity parameters reflect not only the void fraction, which influences the storage capacity of the urban area, but also the influence of buildings on flow conveyance (dynamic effects). A sensitivity analysis was performed based on the inundation maps to highlight the respective impact of each input parameter characteristizing the urban networks. The findings of the study pinpoint

    The aim of this study is to investigate the safety and clinical efficacy of minimally invasive manipulative reduction with poking k-wire fixation in the treatment of various types of calcaneal fractures. Between July 2012 and July 2014, a prospective parallel controlled study was conducted on 96 patients with closed calcaneal fractures who were admitted to our institution. These patients were randomly divided into two groups, with 48 in each group. Patients in plate group were treated using open reduction and internal fixation, whereas those of manipulation group were treated with minimally invasive manipulative reduction with poking k-wire fixation. All patients were followed up for six months to assess the postoperative recovery and complications. Kerr's scale was adopted to evaluate the functional recovery of fractured calcaneus. A mean healing duration of 9.48 ± 1.92 weeks was achieved in patients of plate group compared with a healing duration of 9.35 ± 1.66 weeks in those of manipulation group, with no statistical significance (p > 0.05). Complications occurred in 20 cases in plate group versus in seven cases in manipulation group with significant difference (p fracture, among patients with compression fracture and tongue type fracture, > 70% of patients achieved with excellent and good outcomes in both groups with no significant difference in clinical efficacy (p > 0.05). The rate of excellent and good outcomes in Sanders type III compression fractures was lower in manipulation group than in plate group (p fractures, the Kerr's score of tongue type fractures in manipulation group was higher than that in plate group, and comparison within manipulation group showed that the score of tongue type fractures was significantly higher than that of compression fractures (p fractures, the score of tongue type fractures in manipulation group was significantly higher than that in plate group, and the score of compression fractures in plate group was significantly

    The Mieming massif in the western part of the Northern Calcareous Alps (NCA, Austria) records a complex history of rapid landscape change during the deglacial to paraglacial phase (c. 19.5-17 ka) after the Last Glacial Maximum (LGM). In this succession of changes, a major event that shaped the entire catchment till today was the descend of a rock avalanche of a GIS-estimated volume of 11 Mm3. This rock avalanche: (a) clogged a pre-existing valley, (b) dammed up an intramontane basin (Strassberg basin), and (c) triggered the incision of an epigenetic bedrock gorge some 1.5 km in length (Sanders et al., 2016). Geomorphological and sedimentological indicators all suggest that the rock avalanche descended very soon after local deglaciation, but an age estimate of mass-wasting was difficult to provide. Bulk radiocarbon ages of the acid-washed, humic fraction of soil horizons intercalated into colluvium above the rock avalanche deposit indicated an oldest age of 11180-11170 a cal BP; a large scatter of radiocarbon ages (youngest: 7960 a cal BP; oldest: 11180 a cal BP; total of three ages) indicated that these well-drained soils were subject to input of younger humic substance, thus can provide only a crude proxy ante-quam date for the event. Over the past two years, in the NCA, a landscape-wide drape of polymictic siliciclastic aeolian silt was discovered that - as suggested by its geomorphic and sedimentary context - most probably was deposited during the late-glacial chron. The drape is verified over a vertical relief amplitude of more than 2000 meters, from valley floors up to LGM nunataks (Gild et al., 2016). A level of polymictic siliciclastic silt was found also directly on top of the Strassberg rock avalanche deposit. This provided an opportunity to deduce a more precise ante-quam quartz OSL age of 18.77 ± 1.55 ka for mass-wasting. The high post-glacial event age is consistent with evidence that the clearing of the older trunk valley from LGM sediments was just

    This research is aimed to understand the effect of paraquat herbicide inhalation on Parkinsonism, morphology and anatomy change in mice, and its recovery with Etliringea hemisphaerica crude extract application. Sixty mice were placed into three following groups: group R0 were mice receiving standard food ransom, R1 were a group of mice receiving the regular food ransom plus inhalation of 1% paraquat, and R2 were a group of R1 plus obtaining 0,39mg/bw extract E. hemisphaerica (Bl.) R.M. Smith). After 2 X 7 days of sub-sequential application of both paraquat and “helani tulip” extract, we observed the effects. The examination included bradikinesia attitude, postural instability and rigidity, morphology and anatomy of brain, liver, blood, lung, and kidney. The data were tabulated and analyzed qualitative and semi quantitative description on the behavioural disorder, the alteration of morphology and anatomy, and their remedy based on Sander 2004, Junqueira and Carneiro, 2007. The results showed that the application of paraquat caused strong bradikinesia, postural instability and rigidity. The treatment of the extract was only resulting in the bradikinesia removal but was minor improving the consequence of postural instability and rigidity. Paraquat was not affecting the morphology of neural brain but was altering the morphology and anatomy of lung, liver, blood, and the kidney. In general, the negative impact of the paraquat was weakly eliminated by the treatment of “helani tulip” extract.

    Listeners can estimate the age of a speaker fairly accurately from their speech (Ptacek and Sander, 1966). It is generally considered that this perception is based on physiologically determined aspects of the speech. However, the degree to which it is due to conventional sociolinguistic aspects of speech is unknown. The current study examines the degree to which fundamental frequency (F0) changes due to advanced aging across two language groups of speakers. It also examines the degree to which the speakers associate these changes with aging in a voice disguising task. Thirty native speakers each of English and Japanese, taken from three age groups, read a target phrase embedded in a carrier sentence in their native language. Each speaker also read the sentence pretending to be 20-years younger or 20-years older than their own age. Preliminary analysis of eighteen Japanese speakers indicates that the mean and maximum F0 values increase when the speakers pretended to be younger than when they pretended to be older. Some previous studies on age perception, however, suggested that F0 has minor effects on listeners' age estimation. The acoustic results will also be discussed in conjunction with the results of the listeners' age estimation of the speakers.

    Full Text Available This article provides a response to David Hume’s argument against the plausibility of miracles as found in Section 10 of his An enquiry concerning human understanding by means of Charles Sanders Peirce’s method of retroduction, hypothetic inference, and abduction, as it is explicated and applied in his article entitled A Neglected Argument for the Reality of God, rather than focusing primarily on Peirce’s explicit reaction to Hume in regard to miracles, as found in Hume on miracles. The main focus will be on Peirce’s neglected argument rather than his explicit confrontation with Hume on the issue of miracles, because his criticisms of Hume demands a methodological approach appropriate for scientifically analysing surprising phenomena or outliers, of which miracles or the reality of God would be but two examples amongst many. This article, then, consists of an attempt to construct this method as one that draws inferences neither a priori nor a posteriori, but per posterius, because such a method is capable of rigorously questioning rogue or surprising phenomena, e.g. miracles.

    Full Text Available This paper studies the role of the semiotic discussions of Charles Sanders Peirce, the American philosopher and mathematician, in the formation of Deleuze’s first leading book on cinema, Cinema 1: the Movement-Image,in whichthe author surpasses Peirce’s semiotics. We will show how Deleuze creates a new form of signs in his second leading book on cinema, Cinema 2: the Time-Image. Deleuze had tried to couplethe patterns of Peirce’s semiotics in his first book with the philosophical discussions on different epochs of the classical cinema. In his second book, he tried to surpass Peirce’s semiotics, proposing patterns of new semiotics concerning modern cinema by modeling on Peirce’s semiotics. This paper attempts to propose the Peircian signs in Cinema 1: the Movement-Image and Deleuze’s modeling on the signs in Cinema 2: the Time-Image, showing that such asurpassing for Deleuze is the key point of under-standing philosophy. It helps him to reach his particular semiotics based on both Peirce semiotics and Bergson’s philosophy of time, while being completely different from them: noosign.

    Mercury (Hg) contamination in sport fish is a global problem. In freshwater systems, food web structure, sport fish sex, size, diet and growth rates influence Hg bioaccumulation. Fish stocking is a common management practice worldwide that can introduce external energy and contaminants into freshwater systems. Thus, stocking can alter many of the factors that influence Hg concentrations in sport fish. Here we evaluated the influence of external subsidies, in the form of hatchery-raised rainbow trout Oncorhynchus mykiss on walleye Sander vitreus diet, growth and Hg concentrations in two freshwater systems. Stocking differentially influenced male and female walleye diets and growth, producing a counterintuitive size-contamination relationship. Modeling indicated that walleye growth rate and diet were important explanatory variables when predicting Hg concentrations. Thus, hatchery contributions to freshwater systems in the form of energy and contaminants can influence diet, growth and Hg concentrations in sport fish. Given the extensive scale of fish stocking, and the known health risks associated with Hg contamination, this represents a significant issue for managers monitoring and manipulating freshwater food web structures, and policy makers attempting to develop fish consumption advisories to protect human health in stocked systems.

    Full Text Available A Khan1, G Lascaratos1, T Rane-Malcolm2, R Sanders21Princess Alexandra Eye Pavilion, Edinburgh, 2Department of Ophthalmology, Queen Margaret Hospital, Dunfermline, Fife, UKAbstract: Zolendronic acid is a nitrogenous biphosphonate commonly used as an intravenous infusion for the management of Paget’s disease, osteoporosis, and hypercalcemia of malignancy. We report a rare and challenging complication of zolendronate infusion: unilateral acute anterior uveitis followed by persistently raised intraocular pressure despite being on four different classes of antiglaucoma medication. The challenge was that the patient required topical steroid to treat her uveitis in the background of known glaucoma with corresponding steroid response. She eventually underwent a left phacotrabeculectomy augmented with 5-fluorouracil. Four weeks postoperatively she developed an encapsulated bleb and underwent needling with 5-fluorouracil. This case highlights the importance of having a high index of suspicion for anterior uveitis in patients with a red and painful eye after initiating biphosphonate therapy. Caution should also be exercised when prescribing biphosponates to glaucoma patients.Keywords: biphosponates, anterior uveitis, intraocular pressure

  10. The saw-tooth sign as a clinical clue for intrathoracic central airway obstruction

    Full Text Available Abstract Background The saw-tooth sign was first described by Sanders et al in patients with obstructive sleep apnea syndrome as one cause of extrathoracic central airway obstruction. The mechanism of the saw-tooth sign has not been conclusively clarified. The sign has also been described in various extrathoracic central airway diseases, such as in burn victims with thermal injury to the upper airways, Parkinson’s disease, tracheobronchomalacia, laryngeal dyskinesia, and pedunculated tumors of the upper airway. Case presentation A 61-year-old man was referred to our hospital with a two-month history of persistent dry cough and dyspnea. He was diagnosed with lung cancer located in an intrathoracic central airway, which was accompanied by the saw-tooth sign on flow-volume loops. This peculiar sign repeatedly improved and deteriorated, in accordance with the waxing and waning of central airway stenosis by anti-cancer treatments. Conclusion This report suggests that the so-called saw-tooth sign may be found even in intrathoracic central airway obstruction due to lung cancer.

    Full Text Available This paper presents the preliminary results of a research that investigates the creation of events through social networking sites on the Internet. There is already a specific type of event that serves the logic of these networks, especially those whose production and distribution take place based on online platforms and digital tools. This paper investigates two cases: the first concerns the duo of Brazilian country music singers, Zezé di Camargo and Luciano, who, after an argument that occurred in a concert in the city of Curitiba, announced the end of the partnership. The video was posted on YouTube and was immediately spread through the social networks, which generated intense conversation about the episode until it became a journalistic event in the traditional media. This paper also examines the organization of a protest against the attack on a homoaffective couple in a street of São Paulo in 2011, completely worked on by Facebook. Based on Charles Sanders Peirce’s concept of semiosis, a map of the construction of these events is drawn with its various ramifications, from the articulations within the network to the production of meanings that they develop. The events studied have as an element in common the leading role that social networks had in their constitution. They possess the nature of the network and are framed in what is understood now as cyberevents, a category that poses new challenges to the practice of journalism.

    Full Text Available The article explores the ways of creating addressee’s images in contemporary hemeronyms — names of periodicals. The authors point out the semiotic specificity of hemeronyms used to identify collections of texts united, inter alia, by unified editorial policies and informational conceptions. The addressee factor is important for the pragmatics of naming periodicals and inventing hemeronyms, which are an integrated part of the media discourse. Based on Charles Sanders Peirce’s semiotics, the authors analyze the iconic, indexical and symbolic codes of marking the addressee in the vocabulary constituting contemporary Russian hemeronyms. The semiotic approach results in establishing different levels of the edition’s target audience portrayal and revealing the most frequent devices of its representation in derivative names. The general theoretical suggestions are than illustrated with an analysis of the names of Russian periodicals for women, this leads to precise the communicative and interpretative potential of iconic, indexical and symbolic codes, which differently participate in presenting the edition’s content or creating its unique image. The observations set forth in the paper may be applied for naming new magazines and newspapers.

    The growth of age-0 fishes influences survival, especially in temperate regions where size-dependent over-winter mortality can be substantial. Additional benefits of earlier maturation and greater fecundity may exist for faster growing individuals. This study correlated prey densities, growing-degree days, water-surface elevation, turbidity, and chlorophyll a with age-0 walleye Sander vitreus growth in a south-central Nebraska irrigation reservoir. Growth of age-0 walleye was variable between 2003 and 2011, with mean lengths ranging from 128 to 231 mm by fall (September 30th–October 15th). A set of a priori candidate models were used to assess the relative support of explanatory variables using Akaike's information criterion (AIC). A temperature model using the growing degree-days metric was the best supported model, describing 65% of the variability in annual mean lengths of age-0 walleye. The second and third best supported models included the variables chlorophyll a (r2 = 0.49) and larval freshwater drum density (r2 = 0.45), respectively. There have been mixed results concerning the importance of temperature effects on growth of age-0 walleye. This study supports the hypothesis that temperature is the most important predictor of age-0 walleye growth near the southwestern limits of its natural range.

    To complete the revamp of CERN’s Council Chamber, a new exhibition is being installed just in time for the June Council meetings.   Panels will showcase highlights of CERN’s history, using some of the content prepared for the exhibitions marking 50 years of the PS, which were displayed in the main building last November. The previous photo exhibition in the Council Chamber stopped at the 1970s. To avoid the new panels becoming quickly out of date, photos are grouped together around specific infrastructures, rather than following a classic time-line. “We have put the focus on the accelerators – the world-class facilities that CERN has been offering researchers over the years, from the well-known large colliders to the lesser-known smaller facilities,” says Emma Sanders, who worked on the content. The new exhibition will be featured in a future issue of the Bulletin with photos and an interview with Fabienne Marcastel, designer of the exhibit...

    Identifying the sources of methylmercury (MeHg) and tracing the transformations of mercury (Hg) in the aquatic food web are important components of effective strategies for managing current and legacy Hg sources. In our previous work, we measured stable isotopes of Hg (δ 202 Hg, Δ 199 Hg, and Δ 200 Hg) in the Laurentian Great Lakes and estimated source contributions of Hg to bottom sediment. Here, we identify isotopically distinct Hg signatures for Great Lakes trout ( Salvelinus namaycush) and walleye ( Sander vitreus), driven by both food-web and water-quality characteristics. Fish contain high values for odd-isotope mass independent fractionation (MIF) with averages ranging from 2.50 (western Lake Erie) to 6.18‰ (Lake Superior) in Δ 199 Hg. The large range in odd-MIF reflects variability in the depth of the euphotic zone, where Hg is most likely incorporated into the food web. Even-isotope MIF (Δ 200 Hg), a potential tracer for Hg from precipitation, appears both disconnected from lake sedimentary sources and comparable in fish among the five lakes. We suggest that similar to the open ocean, water-column methylation also occurs in the Great Lakes, possibly transforming recently deposited atmospheric Hg deposition. We conclude that the degree of photochemical processing of Hg is controlled by phytoplankton uptake rather than by dissolved organic carbon quantity among lakes.

    Full Text Available Today, there are many advanced transportation tools developed and created by humans in order to meet all the elements of satisfaction in the human self itself. As in Indonesia itself recently will be built rapid train from Jakarta to the city of Bandung. This is one of the qualified facilities that are expected to fulfill the needs of the society in transportation. But behind it all there are some means of transportation where people are not too interested in all sophistication of technology, but has an artistic, iconic and unique value to use. "Angkot Gaul", so the people of Padang City call it and by the drivers make this transport not only deliver passengers to the destination but has a good point of view to use. Like the car modification, Angkot Gaul is known not only in the city of Padang but also national. So with the uniqueness owned Angkot Gaul is eventually used as a packaging that can increase sales of services well and of course the value of satisfaction both by the driver himself and passengers. What is the iconic value and uniqueness of this public transport? The researcher is looking at the meaning of semiotics using the theory of Charles Sanders Pierce which contained the value of semiotics that contained its meaning on Angkot Gaul Padang City in terms of language, color, music and stickers modified by the driver of Angkot Gaul.

    Osteosynthesis and reposition of the Charcot foot is challenging with respect to choice of a proper implant. There is currently no international consensus regarding the optimal implant. Locking plates seem to be an innovative and stable method for reconstruction. The aim of this work is to analyze bone fusion, complications, pseudoarthrosis, and patient satisfaction. This paper presents a retrospective analysis of 63 consecutive Charcot feet treated between 2004 and 2014. The mean follow-up time was 2.4 years. All Charcot feet treated between 2004 and 2014 were Sanders type II or III. A bony fusion was achieved in 50 % of the cases, 26 % had a functional pseudoarthrosis with intact implants and pain-free mobility, and 22 % showed no healing with broken implants. Conclusion Internal fixation with locking plates is superior to screw fixation only with regard to biomechanics. We prefer internal fixation plates to external fixation because of stability even in the case of pseudoathrosis and because of the learning curve.

  20. Forecasting effects of climate change on Great Lakes fisheries: models that link habitat supply to population dynamics can help

    Future changes to climate in the Great Lakes may have important consequences for fisheries. Evidence suggests that Great Lakes air and water temperatures have risen and the duration of ice cover has lessened during the past century. Global circulation models (GCMs) suggest future warming and increases in precipitation in the region. We present new evidence that water temperatures have risen in Lake Erie, particularly during summer and winter in the period 1965–2000. GCM forecasts coupled with physical models suggest lower annual runoff, less ice cover, and lower lake levels in the future, but the certainty of these forecasts is low. Assessment of the likely effects of climate change on fish stocks will require an integrative approach that considers several components of habitat rather than water temperature alone. We recommend using mechanistic models that couple habitat conditions to population demographics to explore integrated effects of climate-caused habitat change and illustrate this approach with a model for Lake Erie walleye (Sander vitreum). We show that the combined effect on walleye populations of plausible changes in temperature, river hydrology, lake levels, and light penetration can be quite different from that which would be expected based on consideration of only a single factor.

We discuss the issue of suicide in epilepsy with special attention to AEDs and the assessment of suicide in people with epilepsy. It has been suggested that early medical treatment with AEDs might potentially reduce suicide risk of people with epilepsy, but it is of great importance that the choice of drug is tailored to the mental state of the patient. The issue of suicidality in epilepsy is likely to represent an example of how the underdiagnosis of psychiatric symptoms, the lack of input from professionals (eg, psychologists, social workers, and psychiatrists, and the delay in an optimized AED therapy may worsen the prognosis of the condition with the occurrence of severe complications such as suicide.Keywords: epilepsy, suicide, adverse effect, depression

  2. Closed-form Solution for Freely Vibrating Functionally Graded Thick Doubly Curved Panel-A New Generic Approach

    M. Fadaee

    Full Text Available Abstract Today, double curvature shell panels are the main parts of each design because their geometrical characteristics provide high strength to weight ratio, aerodynamic form and beauty for the structures such as boats, submarines, automobiles and buildings. Also, functionally graded materials which present multiple properties such as high mechanical and heat resistant, simultaneously, have attracted designers. So, as the first step of any dynamic analysis, this paper concentrates on presenting a high precision and reliable method for free vibration analysis of functionally graded doubly curved shell panels. To this end, panel is modeled based on third order shear deformation theory and both of the Donnell and Sanders strain-displacement relations. A new set of potential functions and auxiliary variables are proposed to present an exact Levy-type close-form solution for vibrating FG panel. The validity and accuracy of present method are confirmed by comparing results with literature and finite element method. Also, effect of various parameters on natural frequencies are studied which are helpful for designers.

  3. Persistent disturbance by commercial navigation afters the relative abundance of channel-dwelling fishes in a large river

    We provide the first evidence for chronic effects of disturbance by commercial vessels on the spatial distribution and abundance of fishes in the channels of a large river. Most of the world's large rivers are intensively managed to satisfy increasing demands for commercial shipping, but little research has been conducted to identify and alleviate any adverse consequences of commercial navigation. We used a combination of a gradient sampling design incorporating quasicontrol areas with Akaike's information criterion (AIC)-weighted model averaging to estimate effects of disturbances by commercial vessels on fishes in the upper Mississippi River. Species density, which mainly measured species evenness, decreased with increasing disturbance frequency. The most abundant species - gizzard shad (Dorosoma cepedianum) and freshwater drum (Aplodinotus grunniens) - and the less abundant shovelnose sturgeon (Scaphirhynchus platorhynchus) and flathead catfish (Pylodictis olivaris) were seemingly unaffected by traffic disturbance. In contrast, the relative abundance of the toothed herrings (Hiodon spp.), redhorses (Moxostoma spp.), buffaloes (Ictiobus spp.), channel catfish (Ictalurus punctatus), sauger (Sander canadensis), and white bass (Morone chrysops) decreased with increasing traffic in the navigation channel. We hypothesized that the combination of alteration of hydraulic features within navigation channels and rehabilitation of secondary channels might benefit channel-dependent species. ?? 2006 NRC.

    In Lake Erie, Walleye (Sander vitreus vitreus) is king. The naturally occurring species is the foundation of commercial fishing operations on the Canadian side of the lake and is a much-prized sport fish on the American side. Management of Lake Erie walleye fisheries is complex and takes place in an inter-jurisdictional setting composed of resource agencies from the states of Michigan (MDNR), Ohio (ODNR), Pennsylvania (PFBC), and New York (NYDEC) and the province of Ontario (OMNR). The complexity of walleye management is exacerbated by interactions among environmental and ecological changes in Lake Erie, complex life-history characteristics of the species, public demand for walleye, and cultural/governance differences among managing groups and their respective constituents. Success of future management strategies will largely hinge upon our ability to understand these inherent complexities and to employ tactics that successfully accommodate stock productivity and human demand in a highly dynamic environment. In this report, we review the history of Lake Erie walleye management, outline the multi-jurisdictional process for international management of walleye, and discuss strategies to address challenges facing managers.

    Full Text Available Pediatric cataract is the most common treatable cause of blindness in children. Prevalence, etiology and morphology vary with the socioeconomic development. The treatment goal is to reduce amblyopia, being difficult management especially in unilateral cases. The decision on aphakia or primary intraocular lens should be individualized as well as correction with contact lens or spectacles. The intraocular lens single-piece hydrophobic acrylic are the most implanted in children and the preferably is in the capsular bag. The Sanders-Retzlaff-Kraff theoretic (SRK/T stressing that is described as more predictable, following Holladay I and SRK II and the recommendation is to under correction +6.0 or +8.0 dioptrias expecting the growth of the eye. The posterior capsule opacity is the most frequent complication and varies with the material choice of the lens. Glaucoma is the most serious postoperative complication and depends on the timing of the surgery, primary lens implantation and time of post surgical follow-up. The adherence to occlusion therapy with patching is critical to the visual prognosis and is determined by the child’s age and laterality of the cataract. There was significant improvement in the surgery and in IOLs, however the final visual prognosis is still not desirable.

    Increasing use of nanoparticles in different industrial applications has raised a new potential health risk to the workers as well as to the consumers. This study investigates the particle size distributions of sanding dust released from paints produced with and without engineered nanoparticles. Dust emissions from sanding painted plates were found to consist of five size modes; three modes under 1 μm and two modes around 1 and 2 μm. We observed that the sander was the only source of particles smaller than 50 nm and they dominated the number concentration spectra. Mass and surface area spectra were dominated by the 1 and 2 μm modes. Addition of nanoparticles caused only minor changes in the geometric mean diameters of the particle modes generated during sanding of two paints doped with 17 nm TiO2 and 95 nm Carbon Black nanoparticles as compared to the size modes generated during sanding a conventional reference paint. However, the number concentrations in the different size modes varied considerably in between the two NP-doped paints and the reference paint. Therefore, from a physical point of view, there may be a difference in the exposure risk during sanding surfaces covered with nanoparticle-based paints as compared to sanding conventional paints.

    The pupal parasitoids, Spalangia cameroni Perkins and Muscidifurax raptor Girault and Sanders, can be purchased for biological control of house flies Musca domestica L. and stable flies Stomoxys calcitrans (L.) (Diptera: Muscidae). Little is known about the odors involved in host-seeking behavior of these two species, so odors associated with house flies were investigated in the laboratory using a Y-tube olfactometer. Odor stimuli from house fly host puparia, larvae, pine-shavings bedding with horse manure, and developing flies in the pine-shavings-manure substrate were evaluated in bioassays using the two pteromalid species. In choice tests, naïve female S. cameroni were strongly attracted to odor from the substrate containing house fly larvae and secondarily from the uninfested substrate and substrate with puparia versus humidified and purified air. This species also selected the substrate with larvae versus the substrate with the house fly puparia or uninfested substrate. Muscidifurax raptor was attracted to odor from the substrate containing puparia, washed puparia, and substrate with puparia removed.

    2014-02-01

    Full Text Available The aim of the paper is to describe research into secondary-schoolstudent’s conceptions of the selected content matter – the relations in compound sentences – and to reflect the current approach to teaching it. The model of educational reconstruction as described by Jelemenská, Sander and Kattmann (2003 has been chosen as the research framework. First, the research problem is described on the general level, and then it is put into school context. Next, methodology and outcomes of the research are described. Last, the outcomes are summarized and discussed and the author gives recommendations for teaching. The outcomes of the research show that the contemporary process of teaching the matter does not satisfactorily reflect the students´ communication experience and their prior knowledge, and does not match the demands of modern Czech language teaching as it ignores the communication aim. Moreover, the controversies seen among linguists, which are simplified for school purposes, have also appeared in thinking of the research subject. The research suggests that work with authentic language material as a living organism is essential in language teaching. This material behaves according to certain rules which can be grasped more easily if teaching works with the students’ prior language knowledge as mother-tongue speakers, and supports their genuine understanding of the content on the basis of intensive cognitive work.

    2018-01-01

    This article focuses on the prevention of exposure to wood dust when operating electrical hand-held sawing and sanding machines. A laboratory methodology was developed to measure the dust concentration around machines during operating processes. The main objective was to characterize circular saws and sanders, with the aim of classifying the different power tools tested in terms of dust emission (high dust emitter vs. low dust emitter). A test set-up was developed and is described and a measurement methodology was determined for each of the two operations studied. The robustness of the experimental results is discussed and shows good tendencies. The impact of air-flow extraction rate was assessed and the pressure loss of the system for each machine established. For the circular saws, three machines over the nine tested could be classified in the low dust emitter group. Their mean concentration values measured are between 0.64 and 0.98 mg/m 3 for the low dust emitter group and from 2.55 and 4.37 mg/m 3 for the high dust emitter group. From concentration measurements, a machine classification is possible-one for sanding machines and one for sawing machines-and a ratio from 1-7 is obtained when comparing the results. This classification will be helpful when a choice of high performance power tools, in terms of dust emission, must be made by professionals.

  13. Monitoring mercury in freshwater fish in the oil sands region of Northern Alberta : spatial and temporal comparisons to regional mercury concentrations in fish

    2010-01-01

    The Regional Aquatics Monitoring Program (RAMP) was launched to provide a better understanding of the potential effects of oil sands development on aquatic systems, and to address issues important to communities of northern Alberta, such as mercury concentrations in fish. Muskeg dewatering, deforestation, flooding, and air emissions are among the potential mercury sources entering the aquatic systems within the oil sands region. RAMP collects non-lethal tissue samples on an annual basis for mercury analysis from northern pike (Esox lucius), walleye (Sander vitreus), and lake whitefish (Coregonus clupeaformis) in various rivers and lakes within the oil sands region. The purpose is to evaluate the suitability of fisheries resources for human consumption and to evaluate the potential cumulative biological effects on fish. A mercury database was developed based on studies in other regions in Alberta and across Canada in order to provide a regional context to the RAMP monitoring results. Data points from 1975 to 2009 were mapped to evaluate spatial and temporal differences in mercury concentrations and any exceedances of subsistence and general consumption guidelines. This monitoring effort has been instrumental in determining whether changes in mercury concentrations in fish are localized to a specific waterbody or regional in nature.

  16. Using consumption rate to assess potential predators for biological control of white perch

    2011-08-01

    Full Text Available Control of undesirable fishes is important in aquatic systems, and using predation as a tool for biological control is an attractive option to fishery biologists. However, determining the appropriate predators for biological control is critical for success. The objective of this study was to evaluate the utility of consumption rate as an index to determine the most effective predators for biological control of an invasive fish. Consumption rate values were calculated for nine potential predators that prey on white perch Morone americana in Branched Oak and Pawnee reservoirs, Nebraska. The consumption rate index provided a unique and insightful means of determining the potential effectiveness of each predator species in controlling white perch. Cumulative frequency distributions facilitated interpretation by providing a graphical presentation of consumption rates by all individuals within each predator species. Largemouth bass Micropterus salmoides, walleye Sander vitreus and sauger S. canadensis were the most efficient white perch predators in both reservoirs; however, previous attempts to increase biomass of these predators have failed suggesting that successful biological control is unlikely using existing predator species in these Nebraska reservoirs.

  17. Validation of a side-scan sonar method for quantifying walleye spawning habitat availability in the littoral zone of northern Wisconsin Lakes

    Previous research has generally ignored the potential effects of spawning habitat availability and quality on recruitment of Walleye Sander vitreus, largely because information on spawning habitat is lacking for many lakes. Furthermore, traditional transect-based methods used to describe habitat are time and labor intensive. Our objectives were to determine if side-scan sonar could be used to accurately classify Walleye spawning habitat in the nearshore littoral zone and provide lakewide estimates of spawning habitat availability similar to estimates obtained from a transect–quadrat-based method. Based on assessments completed on 16 northern Wisconsin lakes, interpretation of side-scan sonar images resulted in correct identification of substrate size-class for 93% (177 of 191) of selected locations and all incorrect classifications were within ± 1 class of the correct substrate size-class. Gravel, cobble, and rubble substrates were incorrectly identified from side-scan images in only two instances (1% misclassification), suggesting that side-scan sonar can be used to accurately identify preferred Walleye spawning substrates. Additionally, we detected no significant differences in estimates of lakewide littoral zone substrate compositions estimated using side-scan sonar and a traditional transect–quadrat-based method. Our results indicate that side-scan sonar offers a practical, accurate, and efficient technique for assessing substrate composition and quantifying potential Walleye spawning habitat in the nearshore littoral zone of north temperate lakes.

    A risk assessment of the potential impacts of sulphur dioxide (SO 2 ) on the agriculture of central Chile was carried out, using Critical Levels (threshold values above which chronic effects may occur) set by the United Nations Economic Commission for Europe (UNECE, 1993; Sanders et al., 1995), crop sensitivity studies, agricultural land-use data, and air quality data for several years. Ambient SO 2 concentrations around three copper smelters in this region were found to pose a significant risk to crops (such as cereals, staples and legumes) on both local and regional scales. Adverse effects on yield, growth and fruit production were considered possible. Frequent high exposure periods during winter months may also give rise to acute injury in sensitive species and/or crops maintained under optimum water conditions. This study identified high-risk areas, where additional monitoring as well as field studies would be beneficial, and has important policy implications, given the secondary SO 2 air quality standard currently in force in Chile.

  4. Elasto/visco-plastic dynamic response of shells of revolution

    1977-01-01

    The authors study the large deflection elasto/visco-plastic dynamic response of shells of revolution to strong blast loads, where the viscosity of the material is considered in the plastic range. The equations of motion and the relations between the strain and the displacement are derived from the Sanders nonlinear theory for thin shells. The constitutive relation for shell response is linear elastic, visco-plastic. In the linear elastic range Hooke's law is used. In the plastic range the elasto/visco-plastic equations by Fyfe based on the model developed by Perzyna are employed. The criterion for yielding used in this analysis is the von Mises yield theory. The numerical method selected for integration of the equations of motion is a method using finite difference in both space and time. The differential equations are written in finite difference form on the basis of the parabola method. For the time integration of the equations of motion the second-order finite difference in time is used. The equations of motion are thus expressed in finite difference form if we divide the shell into segments along meridional length and around the circumference. Resultant forces and resultant moments are given from numerical integration by Simpson's 1/3 rule. The loadings which are considered in this paper may be either impulsive or of finite time duration.

    Many investigations of the elasto/visco-plastic dynamic response of shells have been conducted. These investigations, however, have been mostly concerned with the case of single-layered shells, and few studies on multi-layered shells have been reported in spite of their importance in engineering. In this paper, the authors study the elasto/visco-plastic dynamic response of the multi-layered shells of revolution subjected to impulsive loads. The equations of motion and the relations between the strains and displacements are derived by extending Sanders' theory for elastic thin shells. As the constitutive relation, Hooke's law is used in the linear elastic range, and the elasto/visco-plastic equations are employed in the plastic range. The criterion for yielding used in the analysis is the von Mises yield theory. In the numerical analysis of the fundamental equations for incremental values an usual finite difference form is employed for the spatial derivatives and the inertia terms are treated with the backward difference formula. The solutions are obtained by summation of the incremental values

  6. Computation of leak areas of circumferential cracks in piping for application in demonstrating leak-before-break behaviour

    1992-01-01

    This paper presents a simplified engineering method to evaluate lower bounds of leak areas for circumferential through-wall cracks in view of their application in demonstrating the Leak-Before-Break behaviour of pipes. Starting from the simple elastic solution in a flat plate, bulging and plasticity correction factors are applied to determine leak rates in pipes. An amplification factor due to bulging is based in Sanders' shell solutions while, for plasticity, the Dugdale-Barenblatt model is used, introducing the reference-stress concept. The method is thus applicable for a large range of diameter-to-thickness ratios and for non-uniform applied loading situations. The method is tested against a number of results obtained either numerically (finite-elements analysis) or experimentally. The results are also compared with other known simplified methods used in the USA and FRG. The simplified approach presented here, to evaluate the crack leak areas in circumferential through-cracks, has been validated on a large range of diameter-to-thickness ratios and for non-uniform applied loads. The method seems promising for demonstration of Leak-Before-Break behaviour of pipes. (orig.)

    Given the increasing complexity of the tasks and skills needed in modern society, developing effective training strategies is of tremendous practical importance. Furthermore, training that improves performance of both trained and untrained tasks would be highly efficient. In the present study, we examined how directed training contributes to skill acquisition, and more importantly, to engendering transfer of training to untrained tasks. Participants learned a complex video game for 30 h (Space Fortress, Donchin, Fabiani, & Sanders, 1989) using one of two training regimens: Hybrid Variable-Priority Training (HVT), with a focus on improving specific skills and managing task priority, or Full Emphasis Training (FET) in which participants simply practiced the game to obtain the highest overall score. We compared game performance, retention of training gains, and transfer of training to untrained tasks as a function of the training regimen. Compared to FET, HVT learners reached higher levels of mastery on the game and HVT was particularly beneficial for initially poor performing participants. This benefit persisted seven months after training. However, contrary to expectation, both HVT and FET were unsuccessful in producing transfer to untrained tasks compared to a group that received limited game experience, suggesting that directed training and practice can produce task-specific improvements, but improvements do not necessarily transfer from trained to untrained tasks.

    An alarming increase in global population is the root cause of poverty, malnutrition, sexually transmitted infections (STIs) and many other social problems. Microbicidal spermicides possessing dual function of contraception and STI protection can effectively combat this problem, and their development is of utmost importance at present. A major metabolite isolated from Shorea robusta resin was spectroscopically characterized as asiatic acid. Spermicidal efficacy of the isolate was evaluated in vitro by a modified Sander-Cramer test. The mode of spermicidal action was assessed by (a) double fluoroprobe staining, (b) hypoosmotic swelling test and (c) scanning electron microscopy. Antimicrobial efficacy was assessed by disc diffusion and broth dilution methods using human isolates of bacteria (Escherichia coli ATCC 25938 and Pseudomonas aeruginosa 71) and fungus (Candida tropicalis). The minimum effective concentration of asiatic acid that induced instantaneous immobilization of rat spermatozoa in vitro was 125 mcg/mL. The mechanism of action involved disruption of sperm plasma membrane. The microbicidal efficacy was found to be moderate for vaginal pathogens, with no effect on normal vaginal flora. Asiatic acid possesses appreciable spermicidal and microbicidal potential and may be explored as an effective microbicidal spermicide. Copyright © 2013 Elsevier Inc. All rights reserved.

    Population availability and vessel avoidance effects on hydroacoustic abundance estimates may be scale dependent; therefore, it is important to evaluate these biases across systems. We performed an inter-ship comparison survey to determine the effect of vessel size, day-night period, depth, and environmental gradients on walleye (Sander vitreus) density estimates in Lake Erie, an intermediate-scaled system. Consistent near-bottom depth distributions coupled with horizontal fish movements relative to vessel paths indicated avoidance behavior contributed to higher walleye densities from smaller vessels in shallow water (i.e., <15 m), although the difference decreased with increasing depth. Diel bank migrations in response to seasonally varying onshore-to-offshore environmental gradients likely contributed to day-night differences in densities between sampling locations and seasons. Spatial and unexplained variation accounted for a high proportion of total variation; however, increasing sampling intensity can mitigate effects on precision. Therefore, researchers should minimize systematic avoidance and availability related biases (i.e., vessel and day-night period) to improve population abundance estimates. Quantifying availability and avoidance behavior effects and partitioning sources of variation provides informed flexibility for designing future hydroacoustic surveys in shallow-water nearshore environments.

    Eleven male walleyes (Sander vitreus) and 10 female walleyes from the Saginaw Bay (Lake Huron) population were caught during the spawning run at Dow Dam (Midland, Michigan) in the Tittabawassee River during April 1996, and individual whole-fish polychlorinated biphenyl (PCB) determinations were made. Total PCB concentrations averaged 7.95 and 3.17??mg/kg for males and females, respectively. As part of the Natural Resource Damage Assessment remediation process, contaminated sediments from the Saginaw River, the main tributary to Saginaw Bay, were removed during 2000 and 2001. Total PCB concentrations of 10 male and 10 female walleyes caught at Dow Dam during April 2007 averaged 1.58 and 0.55??mg/kg, respectively. Thus, dredging of the Saginaw River appeared to be effective in reducing PCB concentrations of Saginaw Bay adult walleyes, as both males and females decreased in PCB concentration by more than 80% between 1996 and 2007. However, the ratio of male PCB concentration to female PCB concentration did not decline between 1996 and 2007. This persistent gender difference in PCB concentrations was apparently due to a gender difference in habitat utilization coupled with a persistent spatial gradient in prey fish PCB concentrations from the Saginaw River to Lake Huron.

    2010-03-01

    Full Text Available Em Empirismo e Filosofia da Mente, de 1956, Wilfrid Sellars criticou a teoria do “mitodo dado”, quer dizer, a ideia de que o conhecimento empírico repousa sobre a fundação de saberesnão-inferenciais. Ao lado de trabalhos de W.V.O. Quine e do “segundo” Wittgenstein, o texto deSellars foi responsável por colocar a filosofia analítica num estágio adiante de suas origens nopositivismo lógico, e também por cultivar o diálogo com o pragmatismo, sobretudo com osfilósofos neopragmatistas. Contudo, quase noventa anos antes do clássico de Sellars, CharlesSanders Peirce, considerado o fundador do pragmatismo, elaborou uma epistemologia póscartesianana qual negava, de modo semelhante, que o conhecimento intuitivo pode servir de basepara crenças. O presente artigo objetiva investigar a proximidade destas teorias, contribuindo paraestreitar as relações entre filosofia analítica e pragmatismo. Conclui-se que Peirce, diferente deSellars, mantém uma forma “saudável” de empirismo “fraco”, que serve de atrito para a elaboraçãoconceitual, ainda que sobre experiências futuras.

    2013-01-21

    Botanical taxonomy is a repository of medical biographical information. Such botanical memorials include the names of some indigenous orchids of Australia. By searching reference texts and journals relating to Australian botany and Australian orchidology, as well as Australian and international medical and botanical biographical texts, I identified 30 orchids indigenous to Australia whose names commemorate doctors and other medical professionals. Of these, 24 have names that commemorate a total of 16 doctors who worked in Australia. The doctors and orchids I identified include: doctor-soldiers Richard Sanders Rogers (1862-1942), after whom the Rogers' Greenhood (Pterostylis rogersii) is named, and Robert Brown (1773-1858), after whom the Purple Enamel Orchid (Elythranthera brunonis) is named; navy surgeon Archibald Menzies (1754-1842), after whom the Hare Orchid (Leptoceras menziesii) is named; radiologist Hugo Flecker (1884-1957) after whom the Slender Sphinx Orchid (Cestichis fleckeri) is named; and general medical practitioner Hereward Leighton Kesteven (1881-1964), after whom the Kesteven's Orchid (Dendrobium kestevenii) is named. Biographic references in scientific names of plants comprise a select but important library of Australian medical history. Such botanical taxonomy commemorates, in an enduring manner, clinicians who have contributed to biology outside clinical practice.

    2008-05-01

    We examined the pressures produced by a construction intended for emergency ventilation through a needle cricothyroidotomy. This construction consisted of a standard hospital wall oxygen supply, flowmeter, oxygen tubing and a three-way tap. We measured the flow achieved through a transtracheal catheter and compared the construction to a Manujet jet ventilator and to a Sanders injector. The construction performed similarly to the Manujet set at low pressures (0-100 kPa). To achieve similar pressures and flow to the Manujet set at pressures higher than 100 kPa required opening of the flowmeter beyond its calibrated range. The flow through the transtracheal catheter was almost three times higher when the flowmeters were fully opened than when they were opened to the 15 l x min(-1) mark (44.5 vs 15.8 l x min(-1), respectively; p mark (285.3 vs 66.4 kPa, respectively; p < 0.0001). This system of ventilation is inferior to a Manujet in terms of robustness and calibration throughout its range of pressures and flows, but seems appropriate for emergency use in the absence of a purpose-made jet ventilator.

  16. Metallic surfaces decontamination by using laser light

    2013-01-01

    Metal surface cleaning appears to be one of the major priorities for industries especially for nuclear industries. The research and the development of a new technology that is able to meet the actual requirements (i.e. waste volume minimization, liquid effluents and chemicals free process...) seems to be the main commitment. Currently, a wide panel of technologies already exists (e.g. blasting, disk sander, electro-decontamination...) but for some of them, the efficiency is limited (e.g, Dry Ice blasting) and for others, the wastes production (liquid and/or solid) remains an important issue. One answer could be the use of a LASER light process. Since a couple of years, the Clean- Up Business Unit of the AREVA group investigates this decontamination technology. Many tests have been already performed in inactive (i.e. on simulants such as paints, inks, resins, metallic oxides) or active conditions (i.e. pieces covered with a thick metallic oxide layer and metallic pieces covered with grease). The paper will describe the results obtained in term of decontamination efficiency during all our validation process. Metallographic characterizations (i.e. SEM, X-ray scattering) and radiological analysis will be provided. We will also focus our paper on the future deployment of the LASER technology and its commercial use at La Hague reprocessing facility in 2013. (authors)

  17. The Adventure of Semiotics

    Full Text Available Linguistic philosophy has become one of the most popular study fields that has overstepped the borders of philosophy in the twentieth century. 1960s are the years of vehement discussions between existentialism, structuralism and Marxism. In these years, the studies of natural languages primarily expanded to cover artificial language studies as well. As a consequence of the influence of these studies, semiotics, trying to resolve and define all of the meaningful systems, has emerged. While Ferdinand de Saussure was forming semiology with his Linguistic studies in Europe on these dates, Charles Sanders Peirce was dealing with determining the principles of semiotics that was going to be used as a framework in order to define the relationships between signs in America. On the other hand, Roland Barthes was accepted as the founder of semiotics with his sign theory in the second half of the 1960s. This paper aims at describing how semiotics has emerged as a result of debates in the language philosophy by examining the first philosophical texts and current discussions.

    Full Text Available T.S. Eliot’s query in The Waste Land, “Who is the third who walks always beside you?” may be said to sum up the hermeneutic situation of any language act, whether of sign production or interpretation. Whereas traditional topoi of expressionist aesthetics, such as the artist’s subjectivity, empirical psychology, truthfulness, intentionality, etc. have become irrelevant in the heteroglottic discourse of the most famous dirge on the decaying West, Eliot’s awareness of the matrical role of cultural semiosis allows us to place him among the founding fathers of semiotic aesthetics. The anagnorisis episode in The Waste Land is one of appropriate reading of the body of Christ through knowledge of the crucifixion scene and associated symbolism.Rooted in the insights of Charles Peirce Sanders and Charles Morris, and enlarged by post-war contributors, such as Roland Barthes, Umberto Eco, Michael B. Hardt, Richard Rudner, Foucault, Vattimo, Baudrillard and Deleuze, the semiotic, cultural materialist, or genetic approach  to art makes interpretation dependent on a mediating third (Peirce: the Interpretant, which is variously related to context, regime of signification, episteme, schemata, generic convention, structure of feeling, triangulation of desire ...

  19. Sanding dust from nanoparticle-containing paints: Physical characterisation

    2009-01-01

    Increasing use of nanoparticles in different industrial applications has raised a new potential health risk to the workers as well as to the consumers. This study investigates the particle size distributions of sanding dust released from paints produced with and without engineered nanoparticles. Dust emissions from sanding painted plates were found to consist of five size modes; three modes under 1 μm and two modes around 1 and 2 μm. We observed that the sander was the only source of particles smaller than 50 nm and they dominated the number concentration spectra. Mass and surface area spectra were dominated by the 1 and 2 μm modes. Addition of nanoparticles caused only minor changes in the geometric mean diameters of the particle modes generated during sanding of two paints doped with 17 nm TiO2 and 95 nm Carbon Black nanoparticles as compared to the size modes generated during sanding a conventional reference paint. However, the number concentrations in the different size modes varied considerably in between the two NP-doped paints and the reference paint. Therefore, from a physical point of view, there may be a difference in the exposure risk during sanding surfaces covered with nanoparticle-based paints as compared to sanding conventional paints.

  20. Migration decisions, agrarian structure, and gender: the case of Ecuador.

    1996-07-01

    This article briefly reviews the literature on migration in Latin America and examines migration decision making in Ecuador. Aggregate data are obtained from the 1974 census of agriculture and population for cantones. Individual level data are obtained from the 1982 census of population. Migration refers to all census persons who recorded differences in their present and previous place of residence during 1974-82. Migration is modeled as dependent upon gender, age, education, marital status, income at origin and at destination, and population pressure or agrarian reform. Logistic model findings indicate that migration decisions are influenced by individual characteristics of migrants and contextual variables. Migration varied by gender. The results confirm Todaro's hypothesis that the probability of migrating is related to income differences between place of destination and origin, but only for males. Findings suggest that females migrate for primary reasons other than economic ones. The probability of migration was greater with increased levels of education. The decision to migrate was affected by quality of life differences, such as literacy rates and levels of urbanization. The probability of migration was reduced by the effects of land reform. Population pressure had a significant effect in increasing migration. The effects of land reform differ from findings in Mexico by William E. Cole and Richard D. Sanders. Land reforms were initiated in 1964 in Ecuador, but by 1974 there was still considerable inequality in land distribution and increased population pressure. Traditional haciendas were modernized, and peasants increased their dependency on non-farm income.

    We examined diets of fishes from gillnet and egg pump collections conducted on reefs in western Lake Erie during walleye (Sander vitreus) egg incubation periods from 1994–1999 and 2004 to assess incidence of walleye eggs in fish diets. We collected no potential egg predators in samples taken in 1994 but from 1995–1999 and in 2004 we caught 22 different species of fish on reefs in addition to spawning walleye. In most years, white perch (Morone americana) stomachs contained more walleye eggs than any other species on the reefs averaging 253 eggs per stomach. We also found lower numbers of walleye eggs in the stomachs of channel catfish (Ictalurus punctatus; 53 eggs/stomach), johnny darter (Etheostoma nigrum; 2 eggs/stomach), logperch (Percina caprodes; 10 eggs/stomach), quillback (Carpiodes cyprinus; 184 eggs/stomach), rock bass (Ambloplites rupestris; 3 eggs/stomach), round goby (Neogobius melanostomus; 4 eggs/stomach), sculpin (Cottidae; 21 eggs/stomach), silver chub (Macrhybopsis storeriana; 3 eggs/stomach), spottail shiner (Notropis hudsonius; 14 eggs/stomach), trout-perch (Percopsis omiscomaycus; 30 eggs/stomach), white sucker (Catastomus commersonii; 20 eggs/stomach), and yellow perch (Perca flavescens; 181 eggs/stomach). Similar to other studies of predation on walleye eggs, our results indicate that prolonged incubation periods increase the potential for egg loss due to predation.

  2. Walleye Autochthonous Bacteria as Promising Probiotic Candidates against Flavobacterium columnare

    Full Text Available Walleye (Sander vitreus is the second most fished freshwater species in Canada. While much sought by anglers, walleye also supports substantial commercial fisheries. To cope with the recent decline of wild walleye populations, fish farmers produce juveniles for lake stocking. However, walleye breeding is particularly tedious, mostly due to high disease susceptibility at larval and juvenile developmental stages. The main threat is the columnaris disease, which is caused by Flavobacterium columnare, an opportunistic bacteria. As F. columnare strains exhibit increasing antibiotic resistance, there is a strong need to develop efficient and sustainable alternative strategies to control columnaris disease. Bacterial probiotics have been shown to mitigate infections either by enhancing host immune response or by inhibiting pathogen growth. Being successfully assessed in many fish/pathogen combinations, we developed a tailored probiotic strategy for walleye to prevent and treat columnaris disease. Thirty-seven endogenous bacterial strains were isolated from healthy walleye’s skin and gut, were tested in vitro against F. columnare. Significant antagonistic effect against F. columnare was measured for 2 out of 37 endogenous strains. These two probiotic strains were identified as Pseudomonas fluorescens. The antagonistic effect of these two successful probiotics was further validated in vivo during a 2-month stress trial: groups receiving probiotic treatments showed on average 53.74% survival improvement.

    The gizzard shad (Dorosoma cepedianum) was introduced into 1,955-ha Angostura Reservoir, South Dakota to provide increased prey resources for walleye (Sander vitreus). Linear correlation analysis indicated that following gizzard shad introduction, walleye catch-per-unit-effort and mean length at age have increased over time (r = 0.68 to 0.85, P = 0.02 to 0.001). Walleye stomach contents were collected monthly from April through September, 2004 to determine the extent to which age-0 gizzard shad were being utilized as prey during the growing season. Age-0 gizzard shad were absent from walleye diets from April to mid-July (pre-shad-available period); however, from mid-July through early September (shad-available period), age-0 gizzard shad were an important prey item in all walleye diets. Mean weight decreased for walleyes of ages 2-5 during the spring, before age-0 gizzard shad became available; however, growth rate of walleyes increased appreciably during the shad-available period and was attributable to consumption of age-0 shad prey. In Angostura Reservoir, which lies at the northwestern edge of the gizzard shad range, walleye population characteristics have improved following shad introduction and during 2004, age-0 shad directly affected walleye feeding and growth.

  4. Terrestrial analogs, planetary geology, and the nature of geological reasoning

    Baker, Victor R.

    2014-05-01

    Analogical reasoning is critical to planetary geology, but its role can be misconstrued by those unfamiliar with the practice of that science. The methodological importance of analogy to geology lies in the formulation of genetic hypotheses, an absolutely essential component of geological reasoning that was either ignored or denigrated by most 20th century philosophers of science, who took the theoretical/ experimental methodology of physics to be the sole model for all of scientific inquiry. Following the seminal 19th century work of Grove Karl Gilbert, an early pioneer of planetary geology, it has long been recognized that broad experience with and understanding of terrestrial geological phenomena provide geologists with their most effective resource for the invention of potentially fruitful, working hypotheses. The actions of (1) forming such hypotheses, (2) following their consequences, and (3) testing those consequences comprise integral parts of effective geological practice in regard to the understanding of planetary surfaces. Nevertheless, the logical terminology and philosophical bases for such practice will be unfamiliar to most planetary scientists, both geologists and nongeologists. The invention of geological hypotheses involves both inductive inferences of the type Gilbert termed “empiric classification” and abductive inferences of a logical form made famous by the 19th century American logician Charles Sanders Peirce. The testing and corroboration of geological hypotheses relies less on the correspondence logic of theoretical/ experimental sciences, like physics, and more on the logic of consistency, coherence, and consilience that characterizes the investigative and historical sciences of interpretation exemplified by geology.

    2012-01-01

    A combined experimental, individual-differences, and thought-sampling study tested the predictions of executive attention (e.g., Engle & Kane, 2004) and coordinative binding (e.g., Oberauer, Süß, Wilhelm, & Sander, 2007) theories of working memory capacity (WMC). We assessed 288 subjects’ WMC and their performance and mind-wandering rates during a sustained-attention task; subjects completed either a go/no-go version requiring executive control over habit, or a vigilance version that did not. We further combined the data with those from McVay and Kane (2009) to: (1) gauge the contributions of WMC and attentional lapses to the worst-performance rule and the tail, or τ parameter, of response time (RT) distributions; (2) assess which parameters from a quantitative evidence-accumulation RT model were predicted by WMC and mind-wandering reports, and (3) consider intra-subject RT patterns – particularly, speeding – as potential objective markers of mind wandering. We found that WMC predicted action and thought control in only some conditions, that attentional lapses (indicated by TUT reports and drift-rate variability in evidence accumulation) contributed to τ, performance accuracy, and WMC’s association with them, and that mind-wandering experiences were not predicted by trial-to-trial RT changes, and so they cannot always be inferred from objective performance measures.

    2014-11-01

    The ecological integrity of freshwater lakes is influenced by atmospheric and riverine deposition of contaminants, shoreline development, eutrophication, and the introduction of non-native species. Changes to the trophic structure of Lake Winnipeg, Canada, and consequently, the concentrations of contaminants and trace elements measured in tissues of native fishes, are likely attributed to agricultural runoff from the 977,800 km(2) watershed and the arrival of non-native zooplankters and fishes. We measured δ(13)C, δ(15)N, and δ(34)S along with concentrations of 15 trace elements in 17 native fishes from the north and south basins of Lake Winnipeg in 2009 and 2010. After adjusting for differences in isotopic baseline values between the two basins, fishes in the south basin had consistently higher δ(13)C and δ(34)S, and lower δ(15)N. We found little evidence of biomagnification of trace elements at the community level, but walleye (Sander vitreus) and freshwater drum (Aplodinotus grunniens) had higher mercury and selenium concentrations with increased trophic position, coincident with increased piscivory. There was evidence of growth dilution of cobalt, copper, manganese, molybdenum, thallium, and vanadium, and bioaccumulation of mercury, which could be explained by increases in algal (and consequently, lake and fish) productivity. We conclude that the north and south basins of Lake Winnipeg represent very different communities with different trophic structures and trace element concentrations. Copyright © 2014 Elsevier B.V.

  8. Modelling future improvements in the St. Louis River fishery ...

    Science.gov (United States)

    The presence of fish consumption advisories has a negative impact on fishing. In the St. Louis River, an important natural resource management goal is to reduce or eliminate fish consumption advisories by remediating contaminant sediments and improving aquatic habitat. However, we currently lack sufficient understanding to estimate the cumulative effects of these habitat improvements on fish contaminant burdens. To address this gap, our study had two main research objectives: first, to determine the relationship between game fish habitat use and polychlorinated biphenyls (PCBs) concentrations in the lower St. Louis River, and two, to calibrate and validate a habitat-based Biota-Sediment Accumulation Factor (BSAF) model that estimates fish PCBs concentration as a function of both sediment and habitat quality. We sampled two resident fishes, Yellow Perch (Perca flavescens) and Black Crappie (Pomoxis nigromaculatus), and two migratory fishes, Northern Pike (Esox lucius) and Walleye (Sander vitreus) of varying size and from locations spread across the St. Louis River estuary, the largest coastal wetland complex in Lake Superior. We found differences in contaminant concentration that were related to habitat usage, though results varied by species. For migratory fishes, increasing diet from Lake Superior was associated with decreasing PCBs concentration in tissue. For resident fishes, PCBs concentration was highest in the industrial portion of the river. Model calibra

    Habitat degradation and harvest have upset the natural buffering mechanism (i.e., portfolio effects) of many large-scale multi-stock fisheries by reducing spawning stock diversity that is vital for generating population stability and resilience. The application of portfolio theory offers a means to guide management activities by quantifying the importance of multi-stock dynamics and suggesting conservation and restoration strategies to improve naturally occurring portfolio effects. Our application of portfolio theory to Lake Erie Sander vitreus (walleye), a large population that is supported by riverine and open-lake reef spawning stocks, has shown that portfolio effects generated by annual inter-stock larval fish production are currently suboptimal when compared to potential buffering capacity. Reduced production from riverine stocks has resulted in a single open-lake reef stock dominating larval production, and in turn, high inter-annual recruitment variability during recent years. Our analyses have shown (1) a weak average correlation between annual river and reef larval production (ρ̄ = 0.24), suggesting that a natural buffering capacity exists in the population, and (2) expanded annual production of larvae (potential recruits) from riverine stocks could stabilize the fishery by dampening inter-annual recruitment variation. Ultimately, our results demonstrate how portfolio theory can be used to quantify the importance of spawning stock diversity and guide management on ecologically relevant scales (i.e., spawning stocks) leading to greater stability and resilience of multi-stock populations and fisheries.

    Full Text Available The aim of the present work was to compare the distribution of selected metals in tissues of several fish species caught in the Věstonice reservoir. The hygienic quality of fish meat was assessed with respect to the mercury concentration. A total of 35 fish of the following species were caught: carp (Cyprinus carpio, bream (Abramis brama, asp (Aspius aspius, pikeperch (Sander lucioperca and pike (Esox lucius. Samples of muscle, liver (hepatopancreas, kidney, gonads and gills were analyzed. Hg, Pb, Cd, Cu, Zn and Cr concentrations in fish tissues were determined by the AAS. The results showed that different metals differ in their affinity to different fish tissues (e.g. Cu - liver, Cd - kidney. Mercury concentrations along the food chain increase, i.e. higher mercury concentrations are found in predatory fish. Contrary to mercury, cadmium and lead concentrations do not show any increases along the fish part of food chain in surface water ecosystems. In predatory fish, lower concentrations of these metals were found than in nonpredatory fish species. Differences in concentrations between ovaria and testes were found only in Cu and Zn. To evaluate possible health risks of mercury concentrations for consumers, the risk index was calculated and maximum admissible amounts of muscle meat for consumption were determined. The results confirmed good hygienic quality of market-ready fish from the Věstonice reservoir.

    Full Text Available Cooperation between the Ottoman Empire and Germany, especially in the sphere of military and communication, began with during the rule of Abdulhamit II. Although it is not exactly clear why the Ottomans preferred Germans instead of the British or French, the Committee of Union and Progress (CUP added another sphere of cooperation: partnership in the First World War against the British and French. The Ottomans invited the German military experts to modernize the military. The German officers were successful in training the Ottoman army and in organizing and strengthening the defenses of the Dardanelles. Then, in accordance with the treaty signed on August 1914 German military mission began to wield "effective influence" over the military operations of the Ottoman armies. German generals and staff officers served as advisers and military commanders for the Ottoman army. Just a month before the Battle of Gallipoli, the Ottomans appointed Otto Liman von Sanders as the commander of the 5th Army. German generals were also put in command of some army corps and divisions. During the Gallipoli campaign, German officers, advisers and experts oversaw placing naval mines in the Dardanelles, organizing coastal defenses, logistics and health care for the army. Their services continued until the end of the First World War.

  15. 87Sr/86Sr isotope ratio analysis by laser ablation MC-ICP-MS in scales, spines, and fin rays as a nonlethal alternative to otoliths for reconstructing fish life history

    2016-01-01

    Strontium isotope ratios (87Sr/86Sr) in otoliths are a well-established tool to determine origins and movement patterns of fish. However, otolith extraction requires sacrificing fish, and when working with protected or endangered species, the use of nonlethal samples such as scales, spines, and fin rays is preferred. Unlike otoliths that are predominantly aragonite, these tissues are composed of biological apatite. Laser ablation multicollector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS) analysis of biological apatite can induce significant interference on mass 87, causing inaccurate 87Sr/86Sr measurements. To quantify this interference, we applied LA-MC-ICP-MS to three marine samples (white seabass (Atractoscion nobilis) otolith; green sturgeon (Acipenser medirostris) pectoral fin ray; salmon shark (Lamna ditropis) tooth), and freshwater walleye (Sander vitreus) otoliths, scales, and spines). Instrument conditions that maximize signal intensity resulted in elevated 87Sr/86Sr isotope ratios in the bioapatite samples, related to a polyatomic interference (40Ca31P16O, 40Ar31P16O). Retuning instrument conditions to reduce oxide levels removed this interference, resulting in accurate 87Sr/86Sr ratios across all tissue samples. This method provides a novel, nonlethal alternative to otolith analysis to reconstruct fish life histories.

    Full Text Available An analysis of nonlinear behaviors of pressure thin-wall pipe segment with supported clearance at both ends was presented in this paper. The model of pressure thin-wall pipe segment with supported clearance was established by assuming the restraint condition as the work of springs in the deformation directions. Based on Sanders shell theory, Galerkin method was utilized to discretize the energy equations, external excitation, and nonlinear restraint forces. And the nonlinear governing equations of motion were derived by using Lagrange equation. The displacements in three directions were represented by the characteristic orthogonal polynomial series and trigonometric functions. The effects of supporting stiffness and supported clearance on dynamic behavior of pipe wall were discussed. The results show that the existence of supported clearance may lead to the changing of stiffness of the pipe vibration system and the dynamic behaviors of the pipe system show nonlinearity and become more complex; for example, the amplitude-frequency curve of the foundation frequency showed hard nonlinear phenomenon. The chaos and bifurcation may emerge at some region of the values of stiffness and clearance, which means that the responses of the pressure thin-wall pipe segment would be more complex, including periodic motion, times periodic motion, and quasiperiodic or chaotic motions.

    Summer is coming - and with it, a new Microcosm exhibition showcasing CERN (see here). But while the new exhibit is preparing to enchant visitors, many have been asking about the site's former content. Will it simply be out with the old and in with the new? Not as such!   The plasma ball from Microcosm is now on display at the LHCb site. As Microcosm's new content is moving in, its old content is moving up. From LHCb to IdeaSquare, former Microcosm displays and objects are being installed across the CERN site. "Microcosm featured many elements that were well suited to life outside of the exhibition," says Emma Sanders, Microcosm project leader in the EDU group. "We didn't want this popular content to go to waste, and so set out to find them new homes across CERN." The LHCb experiment has received a number of Microcosm favourites, including the Rutherford experiment, the cosmic ray display and the Thomson experiment. "We&...

    To investigate the methods of reduction and stable fixation for the treatment of calcaneus fracture involving posterior subtalar articular facet. From September 2004 to September 2008, 31 cases(38 feet) of calcaneus fracture involving posterior subtalar articular facet were treated with open reduction and plate fixation through L incision. There were 24 males and 7 females, with an average age of 39.6 years ranging from 20 to 65 years. All patients underwent systematic CT-scan with coronal and horizontal images and sagittal reconstruction. The classification of the fractures by the Sanders scale showed that there were 22 of type II,14 of type III, 2 of type IV. All cases were followed up for from 12 to 36 months with an average of 25 months, and all the fractures healed without skin flap necrosis. According to the Maryland foot scoring, the total score was (96.2 +/- 8.8) on average, the results were excellent in 32 feet, good in 4 feet, fair in 2 feet. The replacement of the posterior articular facet by X-ray control of Broden and open reduction and internal fixation with calcaneus plate and Schanz-Screw during the operation can keep stable of articular facet, and promote early rehabilitation of calcaneus fracture affected with subtalar joint.

    Supercutaneous (external) fixation with locking plate is utilized for fixation of long bone fractures. One retrospective study for open reduction and supercutaneous fixation of the calcaneus is reported. We prospectively evaluated the use of this method of fixation combined with percutaneous reduction. Between January 2014 and June 2015, 32 displaced calcaneus fractures in 30 patients were stabilized with percutaneous reduction and super-cutaneous fixation. They were 24 males and six females. The mean age was 37.9±5.7 years (21-55). All cases were closed. The time to surgery, complications, radiographic alignment, and time to radiographic union were recorded. Clinical results at the final follow-up were assessed by evaluating Bohler's angles for the radiographic alignment, and the system of the American Orthopedic Foot and Ankle Society (AOFAS) for the functional outcome. According to the Sanders' classification, two cases were type II, 17 cases were type III and 13 cases were type IV. The preoperative average Bohler's angle was 10.57°±4.8. The postoperative X-ray films demonstrated that the average Bohler's angle improved to 29.07°±5.9 (pfracture is an effective method in type II and III and can be effective with type IV but with less favorable results.

    Controversy is ongoing regarding the use of bone grafts to fill cavities that occur with collapse of the posterior facet in the joint and for repair of the calcaneal height with plating. The present study included 40 patients with 43 displaced intra-articular calcaneal fractures treated with open reduction and internal fixation from March 2009 to November 2013. In the present case-control study, the patients were separated into 2 groups: group A received an allograft (20 patients, 22 calcaneal fractures) and group B did not (20 patients, 21 calcaneal fractures). The calcaneal height and Böhler's angle were compared between the 2 groups. The final outcomes for all patients were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle hindfoot scale score and compared between the 2 groups. No significant differences were observed between the groups with regard to the basic demographic variables (p > .05). Using Sanders classification, 8 (18%) were type 2, 19 (44%) were type 3, and 16 (37%) were type 4 fractures. The comparisons between the 2 groups showed a loss of Böhler's angle and loss of calcaneal height that was significantly greater in group B (p  .05). In conclusion, although no differences were found in the clinical results between the 2 groups, more satisfactory radiologic results were obtained in group A, in which bone grafts were used.

    Introduction To reduce complications, a minimally invasive technique for the treatment of dislocated intraarticular fractures of the calcaneus was used. Therefore previously described closed reduction and internal fixation techniques were combined and modified. Materials and methods Sixty-seven out of 92 calcaneal fractures could be retrospectively evaluated with an average follow-up time of 5.7 years (minimum 2–10 years follow-up). For radiographic evaluation, plain radiographs and CT scans were obtained. The Zwipp score was used for clinical evaluation. Sanders type II, III and IV fractures were diagnosed. Results Length of surgery averaged 61 min (range 20–175 min). The incidence of subtalar arthritis was correlated to the severity of fracture. Böhler’s angle was restored in 70.1% (47 of 67) of the cases. On the last follow-up evaluation the average Zwipp score was 130 points (range 48–186 points). The majority (77.7%) of patients were content with their treatment result. The rate of significant complications was 6.5%. Discussion Compared to open techniques the presented minimally invasive technique showed comparable results with a low rate of serious complications and is a viable alternative for the treatment of intraarticular, dislocated calcaneal fractures.

    The locking plate and percutaneous crossing metallic screws and crossing absorbable screws have been used clinically to treat intra-articular calcaneal fractures, but little is known about the biomechanical differences between them. This study compared the biomechanical stability of calcaneal fractures fixed using a locking plate and crossing screws. Three-dimensional finite-element models of intact and fractured calcanei were developed based on the CT images of a cadaveric sample. Surgeries were simulated on models of Sanders type III calcaneal fractures to produce accurate postoperative models fixed by the three implants. A vertical force was applied to the superior surface of the subtalar joint to simulate the stance phase of a walking gait. This model was validated by an in vitro experiment using the same calcaneal sample. The intact calcaneus showed greater stiffness than the fixation models. Of the three fixations, the locking plate produced the greatest stiffness and the highest von Mises stress peak. The micromotion of the fracture fixated with the locking plate was similar to that of the fracture fixated with the metallic screws but smaller than that fixated with the absorbable screws. Fixation with both plate and crossing screws can be used to treat intra-articular calcaneal fractures. In general, fixation with crossing metallic screws is preferable because it provides sufficient stability with less stress shielding.

    Full Text Available Ever since the Supreme Court instituted the one person, one vote principle in congressional elections based on its decision in Wesberry v. Sanders (1964, intrastate deviations from equal district populations have become smaller and smaller after each decennial reapportionment. Relying on equal total population as the standard to meet the Court’s principle, though, has raised some constitutional and practical questions stemming from, most basically, not every person has the right to vote. Specifically, there is considerable deviation between the current redistricting practices and a literal interpretation of this constitutional principle. This study systematically analyzes the differences between districts’ total populations and their voting age populations (VAPs. Further, we consider how congressional reapportionments since 1972 would change if, instead of states’ total populations, the standard for reapportioning seats were based on the VAP or the voting eligible population (VEP. Overall, the results indicate that the debate surrounding the appropriate apportionment and redistricting standard is not just normative, it also has notable practical consequences.

  5. Indigenous fish species in the modern ichthyofauna of the Balkhash basin

    Full Text Available Indigenous fish fauna of the Balkhash basin was mostly formed in the postglacial period and consists of 10 species from Cyprinidae family, 5 from Balitoridae, and 1 from Percidae. More than 20 alien fish species were introduced here during XXth century that led to eradication of indigenous fishes from the Balkhash Lake and the Ili River. Our investigations of the fish fauna during last 25 years revealed permanent shortage of living area of indigenous fishes. Nowadays fish communities from only indigenous fish species exist in some remote and isolated water bodies. Areas of all indigenous fish species are become disconnected. Reduction of habitats goes relatively slow for naked osman Gymnodiptychus dybowskii (Kessler, 1874, spotted thicklip loach Triplophysa strauchii (Kessler, 1874, and gray loach Triplophysa dorsalis (Kessler, 1872. Drastic reductions of areas were revealed for Ili marinka Schizothorax pseudoaksaiensis Herzenstein 1889, Balkhash marinka Schizothorax argentatus Kessler 1874, Severtsov’s loach Triplophysa sewerzowii (G.Nikolskii, 1938, Seven River’s minnow Phoxinus brachyurus Berg 1912, Balkhsh minnow Rhynchocypris poljakowii Kessler 1879, and Balkhash perch Perca schrenkii Kessler 1874. Marinkas, osmans and perch often become victims of overfishing and poaching of local people. In that region water resources usually are used by wasteful way and loaded with pollutants. Many indigenous fish species are able to bear relatively high level of environment pollution. Hence, the main threats for indigenous fishes are introductions of trout and sander, habitats lose and unstable hydrological regimen.

    Presently available contraceptives are mostly hormonal or detergent in nature with numerous side effects like irritation, lesion, inflammation in vagina, alteration of body homeostasis, etc. Antimicrobial peptides with spermicidal activity but without adverse effects may be suitable alternatives. In the present study, spermicidal activity of a cationic antimicrobial peptide VRP on human spermatozoa has been elucidated. Progressive forward motility of human spermatozoa was instantly stopped after 100 μM VRP treatment and at 350 μM, all kinds of sperm motility ceased within 20 s as assessed by the Sander-Cramer assay. The spermicidal effect was confirmed by eosin-nigrosin assay and HOS test. VRP treatment (100 μM) in human spermatozoa induced both the intrinsic and extrinsic pathways of apoptosis. TUNEL assay showed VRP treatment significantly disrupted the DNA integrity and changed the mitochondrial membrane permeability as evident from MPTP assay. AFM and SEM results depicted ultra structural changes including disruption of the acrosomal cap and plasma membrane of the head and midpiece region after treatment with 350 μM VRP. MTT assay showed after treatments with 100 and 350 μM of VRP for 24 hr, a substantial amount of Lactobacillus acidophilus (about 90% and 75%, respectively) remained viable. Hence, VRP being a small synthetic peptide with antimicrobial and spermicidal activity but tolerable to normal vaginal microflora, may be a suitable target for elucidating its contraceptive potentiality. © 2017 Wiley Periodicals, Inc.

    Highlights: •Stochastic weighted algorithms (SWAs) are developed for a detailed silica model. •An implementation of SWAs with the transition kernel is presented. •The SWAs’ solutions converge to the direct simulation algorithm’s (DSA) solution. •The efficiency of SWAs is evaluated for this multidimensional particle model. •It is shown that SWAs can be used for coagulation problems in industrial systems. -- Abstract: This paper presents a detailed study of the numerical behaviour of stochastic weighted algorithms (SWAs) using the transition regime coagulation kernel and a multidimensional silica particle model. The implementation in the SWAs of the transition regime coagulation kernel and associated majorant rates is described. The silica particle model of Shekar et al. [S. Shekar, A.J. Smith, W.J. Menz, M. Sander, M. Kraft, A multidimensional population balance model to describe the aerosol synthesis of silica nanoparticles, Journal of Aerosol Science 44 (2012) 83–98] was used in conjunction with this coagulation kernel to study the convergence properties of SWAs with a multidimensional particle model. High precision solutions were calculated with two SWAs and also with the established direct simulation algorithm. These solutions, which were generated using large number of computational particles, showed close agreement. It was thus demonstrated that SWAs can be successfully used with complex coagulation kernels and high dimensional particle models to simulate real-world systems.

    Bipolar fracture dislocations of the clavicle are rare injuries, usually the result of high-energy direct trauma. Since the original description by Porral in 1831, only a handful of individual case reports and case series by Beckman and Sanders have been reported in the literature. Management of these injuries has remained controversial ranging from nonoperative to aggressive surgery. We report on the case of a young army cadet who had a fracture of the lateral end of the clavicle, with an anterior dislocation of the sternoclavicular joint. Despite being planned for surgery, at the patients request, it was decided to manage the lesion conservatively with graded physiotherapy. At one-year follow-up, he had full pain-free, functional range of movement of the shoulder. This young high demand patient had a good outcome with conservative management, despite going against the current trend towards surgical treatment. We present this case with a review of the literature, highlighting the various management options for this rare lesion.

    Full Text Available The use of composite materials, such as carbon-fiber reinforced plastic (CFRP composites, aero-structures has led to an increased need of advanced assembly joining and repair technologies. Adhesive bonded repairs as an alternative to recover full or part of initial strength were investigated. Tests were conducted with the objective of evaluating the effectiveness of techniques used for repairing damage fiber reinforced laminated composites. Failure loads and failure modes were generated and compared with the following parameters: scarf angles, roughness of grind tool and number of external plies. Results showed that scarf angle was the critical parameter and the largest tensile strength was observed with the smallest scarf angle. Besides, the use of external plies at the outer surface could not increase the repairs efficiency for large scarf angle. Preparing the repair surfaces by sanding them with a sander ranging from 60 to 100 grit number had significant effect on the failure load. These results allowed the proposal of design principles for repairing CFRP structures.

    Nearly all the mercury (Hg) in whole muscle from whitefish (Coregonus clupeaformis) and walleye (Sander vitreus) was present as methyl mercury (MeHg). The Hg content in whole muscle from whitefish and walleye was 0.04-0.09 and 0.14-0.81 ppm, respectively. The myofibril fraction contained approximately three-fourths of the Hg in whitefish and walleye whole muscle. The sarcoplasmic protein fraction (e.g., press juice) was the next most abundant source of Hg. Isolated myosin, triacylglycerols, and cellular membranes contained the least Hg. Protein isolates prepared by pH shifting in the presence of citric acid did not decrease Hg levels. Addition of cysteine during washing decreased the Hg content in washed muscle probably through the interaction of the sulfhydryl group in cysteine with MeHg. Primary and secondary lipid oxidation products were lower during 2 ??C storage in isolates prepared by pH shifting compared to those of washed or unwashed mince from whole muscle. This was attributed to removing some of the cellular membranes by pH shifting. Washing the mince accelerated lipid peroxide formation but decreased secondary lipid oxidation products compared to that of the unwashed mince. This suggested that there was a lipid hydroperoxide generating system that was active upon dilution of aqueous antioxidants and pro-oxidants. ?? 2011 American Chemical Society.

  11. Meaning and Abduction as Process-Structure: A Diagram of Reasoning

    Directory of Open Access Journals (Sweden)

    Inna Semetsky

    2009-11-01

    Full Text Available This paper is informed by Charles Sanders Peirce’s philosophy as semiotics or the doctrine of signs. The paper’s purpose is to explore Peirce’s category of abduction as not being limited to the inference to the best explanation. In the context of the logic of discovery, abduction is posited as a necessary although not sufficient condition for the production of meanings. The structure of a genuine sign is triadic and represents a synthesis between precognitive ideas and conceptual representations. The novel model of reasoning is offered, based on the mathematical formalism borrowed from Gauss’ interpretation of the complex number. It is suggested that this model in a form of a diagram not only represents a semiotic process-structure but also overcomes the long-standing paradox of new knowledge. For Peirce, it is a diagram as a visual representation that may yield solutions to the otherwise unsolvable logical problems. What appears to us as a paradox is the very presence of abductive, or hypothetical, inference, as Peircean generic category of Firstness within the Thirdness of the total thought-process. Firstness (feeling, Secondness (action, and Thirdness (reason together constitute a dynamic structure of experience.

    In this study, tangential migration and neuronal connectivity organization were analysed in the optic tectum of seven different teleosts through the expression of polysialylated neural cell adhesion molecule (PSA-NCAM) in response to ecological niche and use of vision. Reduced PSA-NCAM expression in rainbow trout Oncorhynchus mykiss optic tectum occurred in efferent layers, while in pike Esox lucius and zebrafish Danio rerio it occurred in afferent and efferent layers. Zander Sander lucioperca and European eel Anguilla anguilla had very low PSA-NCAM expression in all tectal layers except in the stratum marginale. Common carp Cyprinus carpio and wels catfish Silurus glanis had the same intensity of PSA-NCAM expression in all tectal layers. The optic tectum of all studied fishes was also a site of tangential migration with sustained PSA-NCAM and c-series ganglioside expression. Anti-c-series ganglioside immunoreactivity was observed in all tectal layers of all analysed fishes, even in layers where PSA-NCAM expression was reduced. Since the optic tectum is indispensable for visually guided prey capture, stabilization of synaptic contact and decrease of neurogenesis and tangential migration in the visual map are an expected adjustment to ecological niche. The authors hypothesize that this stabilization would probably be achieved by down-regulation of PSA-NCAM rather than c-series of ganglioside. © 2017 The Fisheries Society of the British Isles.

Two stages: a) cross-culture adaptation of a questionnaire, and b) cross-sectional study of reliability and validity. Primary care teams in Vizcaya, north of Spain. 118 people who had been widowed between 3 months and 3 years before the study. Cross-culture adaptation: the TRIG was translated from American English, then back-translated and finally compared with the version in American Spanish by Grabowski & Frantz (1993). Reliability: the Cronbach's alpha coefficients (internal consistency) of the 2 TRIG scales were 0.75 and 0.86. Factorial validity: all items except one threw saturation >0.40 on the 2 factors extracted from the varimax rotation. Validity by hypothesis: the TRIG scales showed differences (PGrief Experiences of Sanders et al (1985) and García García et al (2001). In the evaluation of grief due to the death of the spouse, the TRIG adapted to Spanish is as reliable and valid as the original version.

    Full Text Available Zoe-Lydia Tsivos,1 Rachel Calam,1 Matthew R Sanders,1,2 Anja Wittkowski1 1School of Psychological Sciences, University of Manchester, Manchester, UK; 2Parenting and Family Support Center, University of Queensland, Brisbane, Australia Abstract: Postnatal depression (PND has negative effects on maternal well-being as well as implications for the mother–infant relationship, subsequent infant development, and family functioning. There is growing evidence demonstrating that PND impacts on a mother’s ability to interact with sensitivity and responsiveness as a caregiver, which may have implications for the infant’s development of self-regulatory skills, making the infant more vulnerable to later psychopathology. Given the possible intergenerational transmission of risk to the infant, the mother–infant relationship is a focus for treatment and research. However, few studies have assessed the effect of treatment on the mother–infant relationship and child developmental outcomes. The main aim of this paper was to conduct a systematic review and investigate effect sizes of interventions for PND, which assess the quality of the mother–infant dyad relationship and/or child outcomes in addition to maternal mood. Nineteen studies were selected for review, and their methodological quality was evaluated, where possible, effect sizes across maternal mood, quality of dyadic relationship, and child developmental outcomes were calculated. Finally, clinical implications in the treatment of PND are highlighted and recommendations made for further research.

    The efficacy of oxytetracycline hydrochloride (OTC-HCl) in controlling external columnaris disease caused by Flavobacterium columnare on fingerling walleyes Sander vitreus and channel catfish Ictalurus punctatus was evaluated in two on-site hatchery trials. Microscopic examination of skin scrapings before treatment confirmed the presence of bacteria with characteristics indicative of F. columnare.in separate trials, walleyes (4.4 g) and channel catfish (1.5 g) were exposed to 60-min static bath treatments of OTC-HCl at 0, 10, and 20 mg/L (walleyes) or 0, 10, 20, and 40 mg/L (channel catfish) on three consecutive days. Each treatment regimen was tested in triplicate, and each replicate contained either 30 walleyes or 55 channel catfish. Posttreatment presumptive disease diagnosis indicated that F. columnare was the disease agent causing the mortality in both species of fish. Walleye survival at 10 d posttreatment was greater in the 10- and 20-mg/L treatment groups than in the control group; however, only the 10-mg/L treatment significantly (P HCl treatment groups relative to controls. Results from these trials indicated that OTC-HCl treatments effectively reduced mortality in walleyes (10 mg/L only) and channel catfish infected with F. columnare. ??

    This perspective describes the major natural and anthropogenic forces driving change in the abundance and quality of fish habitats in the Huron-Erie Corridor (HEC), the Great Lakes connecting channel comprised of the St. Clair River, the Lake St. Clair, and the Detroit River. Channels connecting the Laurentian Great Lakes discharge large volumes of water equal to or greater than most other large rivers in the world that is of consistent high quality and volume, all year. Owing to creation of the St. Lawrence Seaway through the Great Lakes, the connecting channels have been modified by dredging over 200 km of deep-draft shipping lanes with a maintained depth of no less than 8.2 m. Combined with modification of their shorelines for housing and industries, use of the connecting channels for discharges of industrial and municipal wastes and shipping has resulted in numerous beneficial use impairments, such as restrictions on fish and wildlife consumption, degradation of fish and wildlife populations, and losses of fish and wildlife habitat. Various options for remediation of native fish populations and their habitats in the Great Lakes connecting channels, including construction of spawning habitat for threatened and high-value food fishes, such as lake sturgeon (Acipenser fulvescens), walleye (Sander vitreus), and lake whitefish (Coregonus clupeaformis), have been implemented successfully in two of the channels, and form the basis for further recommended research described in this article.

They play an important role throughout life, as critical modulators of neuronal function and regulation of oxidative stress mechanisms, in brain health and disease. Docosahexanoic acid (DHA, the major omega-3 fatty acid found in neurons, has taken on a central role as a target for therapeutic intervention in Alzheimer’s disease (AD. A plethora of in vitro, animal model, and human data, gathered over the past decade, highlight the important role DHA may play in the development of a variety of neurological and psychiatric disorders, including AD. Cross sectional and prospective cohort data have demonstrated that reduced dietary intake or low brain levels of DHA are associated with accelerated cognitive decline or the development of incipient dementia, including AD. Several clinical trials investigating the effects of omega-3 fatty acid supplementation in AD have been completed and all failed to demonstrate its efficacy in the treatment of AD. However, these trials produced intriguing data suggesting that the beneficial effects of omega-3 fatty acid supplementation may depend on the stage of disease, other dietary mediators, and apolipoprotein E status.Keywords: Alzheimer’s disease, omega-3 fatty acids, oxidative stress, clinical studies, treatment

    This study compares the outcomes of calcaneal fracture surgery after open reduction internal fixation and plating (ORIF) versus arthroscopic assisted percutaneous screw fixation (APSF). Group I (N=12) underwent ORIF. Group II (N=15) underwent APSF. Anthropometric data, pre and post-operative stay, complications and duration off work were recorded in this retrospective case cohort study. Radiographs were analyzed for Bohler's, Gissane's angle and Sanders' classification. AOFAS Hindfoot and SF 36 scores were collected at final follow-up. Anthropometric data, Bohler's and Gissane's angles, AOFAS and SF 36 scores were not significantly different. Pre-operative duration was 12.3 days in ORIF and 6.9 days in APSF. Post-operative duration was 7.3 days vs 3.8 days. Duration off work was 6.2 months vs 2.9 months. The APSF group was able to have surgery earlier, go home faster, and return to work earlier. This study was not powered to demonstrate a difference in wound complication rates. Copyright © 2015 European Foot and Ankle Society. Published by Elsevier Ltd. All rights reserved.
