Published: March 2014

ABSTRACTTo improve the urine distributing mechanism of bladder power pump, a novel urethra valve was proposed in this study. The urine-flow-rate performance equation of the valve was derived on the basis of hydromechanics and electromagnetic theories, and the effect of different parameters on the urine-flow-rate performance was analyzed. The reliability simulation model of the valve was established according to the working principle and fault tree of the valve, a reliability simulation algorithm was proposed based on the basic idea of Monte Carlo method, and some reliability indexes were gained. The results show that increasing electromagnet current and decreasing air gap can increase the maximal urine-flow-rate, the reliability of the valve reaches 0.73 when the average life of the valve is 50000 times, and the shedding and aging of elastic bands are the weak links of the valve. The conclusions can provide the basis for the structural optimization and reliability improvement of bladder power pump, as well as the guidance for the design of implantable biomedicine electromechanical device.

Authors: Rael B. J. , Shen Y.-L. 
Published: March 2014

ABSTRACTAn exotensioned composite structure is developed as a light-weight and low-cost load carrying members for structural applications. The beam body, consisting of carbon-fiber composite skeletons with insertions of high-tension fiber strands, is externally weaved to provide extra structural integrity. Monotonic and cyclic flexural loading experiments are performed in this study to quantify the basic mechanical response of the structure. The bending strength, ductility, and fatigue resistance are specifically assessed.
Laminated Tubes under Extension, Internal and External Pressure

Published: March 2014

AbstractAn exact analysis of deformation and stress field in a laminated elastic tube under extension and uniform pressuring is presented. The problem of finite laminated tube is considered with emphasis on the end effect. The problem is formulated on the basis of the state space formalism for axisymmetric deformation of transversely isotropic layer. The transfer matrix transmits the state vector in radial direction from inner surface to outer surface and takes into account the interfacial continuity and lateral boundary conditions in a rigorous manner. Upon delineating the symplectic orthogonality relations of the eigenvectors and by using eigenfunction expansion, an exact solution which satisfies the end conditions is determined. The results show that the end effect is significant but confined to a local region near the base where the displacement and stress distributions are remarkably different from those according to the simplified solutions that only satisfy lateral BC.
Oscillatory Flow in a Porous Channel with Porous Medium and Small Suction
Authors: Ali A. , Asghar S. 
Published: March 2014

ABSTRACTThis paper deals with an analytical solution of an oscillatory flow in a channel filled with a porous medium saturated with a viscous fluid. The consideration of porosity in the channel is the basic idea of the paper. The oscillatory waves in the channel with porous medium are produced due to self-excited pressure disturbances caused by inevitable fluctuation in a suction rate at the porous walls. The ensuing steady axial velocity and the time dependent oscillatory axial velocity are found analytically using perturbation method and WKB approximation. The important physical quantities like the velocity profile, amplitude of the oscillation and penetration depth of the oscillatory velocity have been given special emphasis in this analysis. The effects of porosity of the medium on these quantities are calculated analytically and examined graphically. We find that the amplitude of oscillatory velocity and the penetration depth of the oscillatory axial velocity decrease with increasing values of inverse Darcy parameter. The oscillations in the fluid can be minimized by decreasing the permeability of the medium.

Published: March 2014

SUMMARYBiogenic nitrogen (N2) and nitrous oxide (N2O) accumulations were measured in groundwater, streams and the vadose zone of small agricultural watersheds in the Mid-Atlantic USA. In general, N2and N2O in excess of atmospheric equilibrium were found in groundwater virtually everywhere that was sampled. Excess N2in groundwater ranged from undetectable to 616 μmol N2-N/l, the latter representingc. 50% of background N2. The N2O-N concentrations varied from undetectable to 75 μm, and usually greatly exceeded values at atmospheric equilibrium (25–30 nM); however, N2O was generally 1–10% of excess N2. Intermediate levels of deficit and excess N2in flowing streams (−65 to +250 μmol N2-N/L) resulting from both abiotic and biotic processes were also measured. In vadose zone gases, multiple N2/Ar gas profiles were measured which exhibited seasonal variations with below atmospheric values when the soil was warming in spring/summer and above atmospheric values when groundwater was cooling in fall/winter. Both abiotic and biotic processes contributed to the excess N2and N2O that was observed. The current data indicate that large concentrations of excess N gases can accumulate within soil, groundwater, and streams of agriculturally dominated watersheds. When excess N gases are exchanged with the atmosphere, the net fluxes to the atmosphere may represent an important loss term for watershed N budgets.
Forage and seed yield of winter turnip rape established as a mixed crop with cereals

Published: March 2014

SUMMARYCultivation of winter turnip rape (Brassica rapa L. ssp. oleifera (DC.) Metzg.) in Finland has been limited because of its reputation as an unreliable crop and its mid-season sowing time of July, when fields are already sown to other crops. An alternative management practice for winter turnip rape is proposed whereby it would be sown as a mixed crop simultaneously with spring cereals. The growth and yield formation of winter turnip rape grown in mixed stands with four different spring cereals was studied in two field experiments conducted in 2009–11. Pure and mixed stands of winter turnip rape and spring cereals were established in May at two different cereal and winter turnip rape stand densities. Subsequent to cereal harvest, one-third of each winter turnip rape plot was harvested for biomass in autumn, before cessation of growth. Three plant stand types, May- and July-sown monocrops and a mixed crop with oat (Avena sativa L.) were sampled for forage analysis. Plant stand densities were monitored from establishment until maturity. Winter turnip rape yield and its quality, including oil content, protein content and thousand seed weight, were determined. Following favourable overwintering conditions, winter turnip rape established with cereals yielded comparably to that of pure stands in terms of both quantity and quality. However, a pure stand of winter turnip rape out-yielded mixed crop stands after unfavourable overwintering conditions. Leaf removal decreased plant survival and seed yield. Establishing winter turnip rape with a cereal in May is an alternative to sowing it as a monocrop in July. A higher seeding rate is needed for under-sown winter turnip rape. Furthermore, autumn-harvested winter turnip rape monocrop forage potentially represents a high-protein supplement for ruminants.
The number of pairwise non-elementarily-embeddable models
Authors: Shelah Saharon 
Published: March 2014

AbstractWe get consistency results on I(λ, T, T) under the assumption that D(T) has cardinality > ∣T∣. We get positive results and consistency results on IE(λ, T1, T).The interest is model-theoretic, but the content is mostly set-theoretic: in Theorems 1–3, combinatorial; in Theorems 4–7 and 11(2), to prove consistency of counterexamples we concentrate on forcing arguments; and in Theorems 8–10 and 11(1), combinatorics for counterexamples; the rest are discussion and problems. In particular:(A) By Theorems 1 and 2, if T ⊆ T1 are first order countable, T complete stable but ℵ0-unstable, λ > ℵ0, and ∣D(T)∣ > ℵ0, then IE(λ, T1, T) > Min{2λ, ℶ2}.(B) By Theorems 4,5,6 of this paper, if e.g. V = L, then in some generic extension of V not collapsing cardinals, for some first order T ⊆ T1, ∣T∣ = ℵ0, ∣T1∣ = ℵ1, ∣D(T)∣ = ℵ2 and IE(ℵ2, T1, T) = 1.This paper (specifically the ZFC results) is continued in the very interesting work of Baldwin on diversity classes [Bl]. Some more advances can be found in the new version of [Sh300] (see Chapter III, mainly §7); they confirm 0.1, 0.2 and 14(1), 14(2).
Types of simple α-recursively enumerable sets
Authors: Leggett Anne , Shore Richard A. 
Published: March 2014

One general program of α-recursion theory is to determine as much as possible of the lattice structure of (α), the lattice of α-r.e. sets under inclusion. It is hoped that structure results will shed some light on whether or not the theory of (α) is decidable with respect to a suitable language for lattice theory. Fix such a language ℒ.Many of the basic results about the lattice structure involve various sorts of simple α-r.e. sets (we use definitions which are definable in ℒ over (α)). It is easy to see that simple sets exist for all admissible α. Chong and Lerman [1] have found some necessary and some sufficient conditions for the existence of hhsimple α-r.e. sets, although a complete determination of these conditions has not yet been made. Lerman and Simpson [9] have obtained some partial results concerning r-maximal α-r.e. sets. Lerman [6] has shown that maximal α-r.e. sets exist iff a is a certain sort of constructibly countable ordinal. Lerman [5] has also investigated the congruence relations, filters, and ideals of (α). Here various sorts of simple sets have also proved to be vital tools. The importance of simple α-r.e. sets to the study of the lattice structure of (α) is hence obvious.Lerman [6, Q22] has posed the following problem: Find an admissible α for which all simple α-r.e. sets have the same 1-type with respect to the language ℒ. The structure of (α) for such an α would be much less complicated than that of (ω). Lerman [7] showed that such an α could not be a regular cardinal of L. We show that there is no such admissible α.
λ-scales, κ-Souslin sets and a new definition of analytic sets
Authors: Busch Douglas R. 
Published: March 2014

SummaryThe notions of sets of reals being κ-Souslin (κ a cardinal) and admitting a λ-scale (λ an ordinal) are due respectively to D. A. Martin and Y.N. Moschovakis. A set is ω-Souslin if and only if it is Σ11 (analytic). We show that a set is ω-Souslin if and only if it admits an (ω + l)-scale. Jointly with Martin and Solovay we show that if κ is uncountable and has cofinality ω, then being κ-Souslin is equivalent to admitting a κ-scale. Our results together with those of Kechris give a new simultaneous characterization of Σ11 and Δ11 (Borel) sets (a set is Σ11 if it admits an (ω + 1)-scale and Δ11 if it admits an ω-scale) and determine completely the relation between the κ-Souslin sets and the sets admitting λ-scales.
On Σ1 well-orderings of the universe
Authors: Harrington Leo , Jech Thomas 
Published: March 2014

The constructible universe L of Gödel [2] has a natural well-ordering <L given by the order of construction; a closer look reveals that this well-ordering is definable by a Σ1 formula. Cohen's method of forcing provides several examples of models of ZF + V ≠ L which have a definable well-ordering but none is definable by a relatively simple formula.Recently, Mansfield [7] has shown that if a set of reals (or hereditarily countable sets) has a Σ1, well-ordering then each of its elements is constructible. A question has thus arisen whether one can find a model of ZF + V ≠ L that has a Σ1 well-ordering of the universe. We answer this question in the affirmative.The main result of this paper isTheorem. There is a model of ZF + V ≠ L which has a Σ1 well-ordering.The model is a generic extension of L by adjoining a branch through a Suslin tree with certain properties. The branch is a nonconstructible subset of ℵ1. Note that by Mansfield's theorem, the model must not have nonconstructible subsets of ω.Our results can be generalized in several directions. We note that in particular, we can get a model with a Σ1 well-ordering that is not L[X] for any set X. As one might expect from a joint paper by a recursion theorist and a set theorist, the proof consists of a construction and a computation.

Published: March 2014

AbstractThe loss of tropical forests and associated biodiversity is a global concern. Conservation efforts in tropical countries such as India have mostly focused on state-administered protected areas despite the existence of vast tracts of forest outside these areas. We studied hornbills (Bucerotidae), an ecologically important vertebrate group and a flagship for tropical forest conservation, to assess the importance of forests outside protected areas in Arunachal Pradesh, north-east India. We conducted a state-wide survey to record encounters with hornbills in seven protected areas, six state-managed reserved forests and six community-managed unclassed forests. We estimated the density of hornbills in one protected area, four reserved forests and two unclassed forests in eastern Arunachal Pradesh. The state-wide survey showed that the mean rate of encounter of rufous-necked hornbills Aceros nipalensis was four times higher in protected areas than in reserved forests and 22 times higher in protected areas than in unclassed forests. The mean rate of encounter of wreathed hornbills Rhyticeros undulatus was twice as high in protected areas as in reserved forests and eight times higher in protected areas than in unclassed forests. The densities of rufous-necked hornbill were higher inside protected areas, whereas the densities of great hornbill Buceros bicornis and wreathed hornbill were similar inside and outside protected areas. Key informant surveys revealed possible extirpation of some hornbill species at sites in two protected areas and three unclassed forests. These results highlight a paradoxical situation where individual populations of hornbills are being lost even in some legally protected habitat, whereas they continue to persist over most of the landscape. Better protection within protected areas and creative community-based conservation efforts elsewhere are necessary to maintain hornbill populations in this biodiversity-rich region.

SUMMARYBluetongue is a disease of major economic concern in Europe. Its causative agent, bluetongue virus (BTV), is transmitted by several Culicoides species (mainly Culicoides imicola and Culicoides obsoletus in Europe). The application of insecticides on animals may reduce transmission of BTV, however, no formulation is currently licensed specifically against Culicoides midges. The present study assesses the susceptibility of C. obsoletus to deltamethrin using an adapted World Health Organization (WHO) susceptibility test. Midges were exposed to different dosages of deltamethrin for 1 h, and mortality after 1 h and 24 h was recorded. Results indicated that deltamethrin is highly toxic to C. obsoletus since a dose of 1·33×10−4% was enough to kill 50% of the population (LD50) in 24 h. The deltamethrin concentration needed to kill 90% of the population (LD90) was 5·55×10−4%. The results obtained in the present work could help to create a system that can be used to assess insecticide resistance and susceptibility of Culicoides biting midges.
Disinhibited social engagement in postinstitutionalized children: Differentiating normal from atypical behavior
Authors: Lawler Jamie M. , Hostinar Camelia E. , Mliner Shanna B. , Gunnar Megan R. 
Published: March 2014

AbstractThe most commonly reported socially aberrant behavior in postinstitutionalized (PI) children is disinhibited social engagement (DSE; also known as indiscriminate friendliness). There is no gold standard for measurement of this phenomenon nor agreement on how to differentiate it from normative behavior. We adopted a developmental psychopathology approach (Cicchetti, 1984) to study this phenomenon by comparing it to normative social development and by studying its patterns over time in 50 newly adopted PI children (16–36 months at adoption) compared with 41 children adopted early from foster care overseas and 47 nonadopted (NA) controls. Using coded behavioral observations of the child's interaction with an unfamiliar adult, atypical behaviors were differentiated from normative behaviors. Principal components analysis identified two dimensions of social disinhibition. The nonphysical social dimension (e.g., initiations, proximity) showed wide variation in NA children and is therefore considered a typical form of sociability. Displays of physical contact and intimacy were rare in NA children, suggesting that they represent an atypical pattern of behavior. Both adopted groups demonstrated more physical DSE behavior than NA children. There were no group differences on the nonphysical factor, and it increased over time in all groups. Implications for understanding the etiology of DSE and future directions are discussed.

AbstractThe relative influence of amyloid burden, neuronal structure and function, and prior cognitive performance on prospective memory decline among asymptomatic late middle-aged individuals at risk for Alzheimer's disease (AD) is currently unknown. We investigated this using longitudinal cognitive data from 122 middle-aged adults (21 “Decliners” and 101 “Stables”) enrolled in the Wisconsin Registry for Alzheimer's Prevention who underwent multimodality neuroimaging [11C-Pittsburgh Compound B (PiB),18F-fluorodeoxyglucose (FDG), and structural/functional magnetic resonance imaging (fMRI)] 5.7 ± 1.4 years (range = 2.9–8.9) after their baseline cognitive assessment. Covariate-adjusted regression analyses revealed that the only imaging measure that significantly distinguished Decliners from Stables (p= .027) was a Neuronal Function composite derived from FDG and fMRI. In contrast, several cognitive measures, especially those that tap episodic memory, significantly distinguished the groups (p's<.05). Complementary receiver operating characteristic curve analyses identified the Brief Visuospatial Memory Test-Revised (BVMT-R) Total (.82 ± .05,p< .001), the BVMT-R Delayed Recall (.73 ± .06,p= .001), and the Reading subtest from the Wide-Range Achievement Test-III (.72 ± .06,p= .002) as the top three measures that best discriminated the groups. These findings suggest that early memory test performance might serve a more clinically pivotal role in forecasting future cognitive course than is currently presumed. (JINS, 2014,20, 1–12)
I'm Not Watching I'm Waiting: the Construction of Visual Codes about Womens' Role as Spectators in the Trial in Nineteenth Century England
Authors: Mulcahy Linda 
Published: March 2014

AbstractAccounts of the interface between law, gender and modernity have tended to stress the many ways in which women experienced the metropolis differently from men in the nineteenth century. Considerable attention has been paid to the notion of separate spheres and to the ways in which the public realm came to be closely associated with the masculine worlds of productive labour, politics, law and public service. Much art of the period draws our attention to the symbiotic relationship between representations of gender and prevailing notions of their place. Drawing on well known depictions of women onlookers in the trial in fine art, this essay by Linda Mulcahy explores the ways in which this genre contributed to the disciplining of women in the public sphere and encouraged them to go no further than the margins of the law court.
Articulating and Contesting Cultural Hierarchies: Guatemalan, Mexican, and Native American Music at the Panama-Pacific International Exposition (1915)
Authors: CANNATA AMANDA 
Published: March 2014

AbstractThree case studies, on Guatemalan, Mexican, and Native American music performed at San Francisco's 1915 Panama-Pacific International Exposition, illustrate the complex and varied ways that music can both reflect and challenge dominant and local ideologies of cultural value. The Guatemalan Commission made a claim for cultural significance through the Hurtado Royal Marimba Band's residency in their pavilion. This claim, however, was made through a Euro-American framework of cultural progress; the band's performances thus obscured the important role of Afro-Guatemalans and indigenous groups in the nation's marimba tradition. Although the “Mexican Village” depicted Mexico as exotic and primitive, the daily performances of the Orquesta Típica Torreblanca in the village showcased the country's cosmopolitan side. Native Americans were frequently subjected to exoticizing and racist musical ventriloquism at the PPIE, yet on at least one occasion a group of Blackfoot people refused this imposition and used music to push for control over their representation. The presence of these musics and musicians, largely ignored in the exposition's official administrative record, demonstrates the shifting power dynamics that shaped the performance and reception of music on the fairgrounds, and reveals that even in environments heavily shaped by dominant ideologies of race, gender, and class, multiple discourses of power and value can circulate.
