Resiliency and the subjective evaluation of health in mothers of children with Asperger’s syndrome
Authors: Kasprzak Arleta , Basińska Małgorzata A. , Lewandowska Paulina 
Published: April 2014

<b>Background</b><br />
Parents caring for children with developmental disorders are exposed to much higher levels of stress than parents of typically developing children. It has also been proved that parents of children with developmental disorders experience mental health deterioration, a sense of guilt, physical weakness, fatigue and exhaustion. Resiliency conditions cognitive and emotional flexibility, and enables an individual to adjust their own behavior to particular circumstances. The present study aims to verify whether there is a relationship between resiliency and the subjective evaluation of health under stress in a group of mothers of children with Asperger’s syndrome. <br />
<br />
<b>Participants and procedure</b><br />
The three measures used in the study were The Polish Resiliency Assessment Scale, The Subjective Evaluation of Health Scale, and a personal questionnaire. A group of 31 mothers of children with Asperger’s syndrome and a group of 31 mothers whose children were not chronically ill and developed typically were examined.<br />
<br />
<b>Results</b><br />
Mothers of children with Asperger’s syndrome have similar levels of resiliency and its contributing factors compared to mothers with healthy children. However, when compared to mothers of healthy children, mothers of children with Asperger’s syndrome show a more negative subjective evaluation of health. Moreover, we found that some resiliency factors (The ability to tolerate failures and view life as a challenge, and Optimism in life and the ability to focus in adversity) correlate positively only in the group of mothers of children with Asperger’s syndrome.<br />
<br />
<b>Conclusions</b><br />
Findings obtained in the study allow us to consider resiliency along with having a healthy child, as a factor contributing to a positive evaluation of health.
Polish normalization of the Body Esteem Scale
Authors: Lipowska Małgorzata , Lipowski Mariusz 
Published: April 2014

<b>Background</b><br />
Physical attractiveness plays an important part in one’s social functioning. The interest in one’s own appearance have been documented as widespread among the female population, but over the recent years it is more and more often emphasized that concentrating on body appearance concerns men as well. Franzoi and Shields (1984) created the Body Esteem Scale which allows to qualify the subject’s attitude towards his or her own body. <br />
The aim of the study was to create a Polish version of the Body Esteem Scale along with the norms for age and sex clusters.<br />
<br />
<b>Participants and procedure</b><br />
The normalization sample consisted of 4298 participants: 1865 women aged 16 to 80 (M = 29.92; SD = 12.85) and 2433 men aged 16 to 78 (M = 28.74; SD = 11.50). Education levels among the participants were also controlled for. <br />
In order to create a Polish version of the Body Esteem Scale, translation was adopted as the adaptation strategy. Like the original one, the Polish scale comprises 35 items grouped into three gender specific subscales. The subscales for women include Sexual Attractiveness, Weight Concern, and Physical Condition, whereas the body esteem of is examined with regards to Physical Attractiveness, Upper Body Strength, and Physical Condition.<br />
<br />
<b>Results</b><br />
Reliability of subscales was high both for females (Cronbach’s alpha from 0.80 to 0.89) and males (Cronbach’s alpha from 0.85 to 0.88).<br />
The given coefficients of reliability cover the original division into subscales adopted by the authors of BES.<br />
<br />
<b>Conclusions</b><br />
We confirmed high reliability of the Polish version of the Body Esteem Scale, thus we recommend it as a diagnostic tool. Created norms allowed to refer results obtained in the course of research carried out on people with various disorders (e.g. eating disorders or body dysmorphic disorder) with population data for corresponding age brackets.

Większość chorych na toczeń rumieniowaty układowy (TRU) jest w wieku prokreacyjnym. Średni wiek zachorowania na TRU to 29 lat. Inaczej niż w przebiegu reumatoidalnego zapalenia stawów, w czasie ciąży u chorych na TRU choroba pozostaje nadal aktywna lub może nawet dojść do jej zaostrzenia. Ciąża – przygotowanie do niej, przebieg, okres karmienia piersią – stanowi poważne wyzwanie terapeutyczne i organizacyjne dla lekarzy opiekujących się chorymi na TRU. Prowadzenie ciąży oraz okres połogu u chorej na TRU wymaga ścisłej współpracy lekarzy różnych specjalności, w tym przede wszystkim reumatologa i położnika. W pracy zostały przedstawione zalecenia dotyczące przygotowania do ciąży, leczenia choroby podstawowej oraz powikłań ciążowych w czasie ciąży i w okresie karmienia piersią u chorych na TRU. Szczególną uwagę zwrócono na leczenie zgodnie z ostatnio opublikowanymi rekomendacjami dla chorych na toczniowe zapalenie nerek.

Układowe choroby tkanki łącznej, a szczególnie reumatoidalne zapalenie stawów i toczeń rumieniowaty układowy, często występują u kobiet w wieku reprodukcyjnym. Znany jest istotny wpływ tych chorób na przebieg ciąży i odwrotnie – przebieg układowych chorób tkanki łącznej może być modyfikowany przez ciążę. Ryzyko wystąpienia poważnych powikłań ciąży i niepowodzeń położniczych znacznie się zwiększa w tej grupie chorób. U podstaw sukcesu położniczego, którym jest urodzenie zdrowego dziecka i brak wpływu ciąży na przebieg choroby autoimmunizacyjnej, leży współpraca reumatologów z położnikami w celu zaplanowania prokreacji w optymalnym okresie oraz odpowiedniego monitorowania przebiegu ciąży. W artykule przedstawiono zalecenia dotyczące postępowania antykoncepcyjnego, nadzoru położniczego oraz monitorowania dobrostanu płodu z punktu widzenia lekarza położnika.

Uzyskane wyniki potwierdzają konieczność stosowania postępowania rehabilitacyjnego w przebiegu choroby zwyrodnieniowej stawu biodrowego.
Linear mode conversion of Langmuir/z mode waves to radiation: Averaged energy conversion efficiencies, polarization, and applications to Earth's continuum radiation
Authors: Schleyer Fiona , Cairns Iver H. , Kim Eun‐Hwa 
Published: April 2014

AbstractLinear mode conversion (LMC) is the linear transfer of energy from one wave mode to another in a density gradient. It is relevant to planetary continuum radiation, type II and III radio bursts, and ionospheric radio emissions. This paper analyzes LMC by calculating angle‐averaged energy (ε) and power (εp) conversion efficiencies in both 2‐D and 3‐D for Langmuir/z mode waves (including upper hybrid waves for perpendicular wave vectors) converting to free‐space radiation in turbulent plasmas. The averages are over the distributions of the incoming Langmuir/z mode wave vectors k, density scale lengths L, and angles α and δ, where α is the angle between k and the background magnetic field B0 and δ is the angle between the density gradient ∇N0 and B0. The results show that the averaged and unaveraged conversion efficiencies are dependent on γβ, where γ is the adiabatic index and β is related to the electron temperature Te by β = Te/mec2. The averaged energy conversion efficiencies are proportional to γβ in 2‐D and to (γβ)3/2 in 3‐D, whereas the power conversion efficiencies are proportional to (γβ)1/2 in 2‐D and γβ in 3‐D. The special case of a perpendicular density gradient (δ≈90°) is considered and used to predict the conversion efficiencies of terrestrial continuum radiation (TCR) in three known source regions: the plasmapause, magnetopause, and the plasma sheet. The observed energy conversion efficiencies are estimated and are found to be consistent with the 2‐D and 3‐D predicted efficiencies; importantly, these results imply that LMC is a possible generation mechanism for TCR. The polarization of TCR is also predicted: TCR should be produced primarily in the o mode at the plasmapause and in both the o and x modes at the magnetopause and plasma sheet. These predictions are consistent with previous independent predictions and observations.
Large‐scalequantization from local correlations in space plasmas
Authors: Livadiotis George , McComas David J. 
Published: April 2014

AbstractThis study examines the large‐scale quantization that can characterize the phase space of certain physical systems. Plasmas are such systems where large‐scale quantization,ħ*, is caused by Debye shielding that structures correlations between particles. The value ofħ*is constant—some 12 orders of magnitude larger than the Planck constant—across a wide range of space plasmas, from the solar wind in the inner heliosphere to the distant plasma in the inner heliosheath and the local interstellar medium. This paper develops the foundation and advances the understanding of the concept of plasma quantization; in particular, we (i) show the analogy of plasma to Planck quantization, (ii) show the key points of plasma quantization, (iii) construct some basic quantum mechanical concepts for the large‐scale plasma quantization, (iv) investigate the correlation between plasma parameters that implies plasma quantization, when it is approximated by a relation between the magnetosonic energy and the plasma frequency, (v) analyze typical space plasmas throughout the heliosphere and show the constancy of plasma quantization over many orders of magnitude in plasma parameters, (vi) analyze Advanced Composition Explorer (ACE) solar wind measurements to develop another measurement of the value ofħ*, and (vii) apply plasma quantization to derive unknown plasma parameters when some key observable is missing.
Temperature dependence of the water vapor self‐continuum by cavity ring‐down spectroscopy in the 1.6 µm transparency window
Authors: Mondelain D. , Manigand S. , Kassi S. , Campargue A. 
Published: April 2014

AbstractThe very weak water vapor self‐continuum has been investigated by high‐sensitivity cavity ring‐down spectroscopy in the 1.6 µm window at five temperatures between 302 K and 340 K. The absorption cross sections, Cs(ν, T), were retrieved for 10 selected wave numbers from a fit of the absorption coefficients measured in real time during pressure ramps, after subtraction of the contributions of the local water monomer lines and of water adsorbed on the cell mirrors. The values measured between 5875 and 6665 cm−1 range between 1.5 × 10−25 and 2 × 10−24 cm2 mol−1 atm−1 with a minimum around 6300 cm−1. At 302 K, an agreement within 50% is observed over the whole window with the cross sections provided by the MT_CKD V2.5 model. Nevertheless, while our measurements show that the Cs(ν, T) decrease from 302 K to 340 K is no more than 50% for all our selected wave numbers, the MT_CKD V2.5 model predicts a much more pronounced temperature dependence in the center of the window, the agreement being better on the edges of the window. The obtained results are discussed in relation with theoretical modeling of the water vapor self‐continuum as far wings of monomer lines or water dimer absorption. For potential atmospheric applications, cross sections are provided at each temperature with a sampling step of 10 cm−1 for the entire 5850–6700 cm−1 range.
Characterization of runoff‐storage relationships by satellite gravimetry and remote sensing
Authors: Riegger J. , Tourian M. J. 
Published: April 2014

AbstractGRACE observations of the time‐dependent gravity field provide a direct measurement of the monthly state of mass and thus monthly total water storage in a catchment. This for the first time allows for a direct comparison of monthly runoff and water storage. Investigations of global scale Runoff‐Storage (R‐S) relationships for different climatic conditions show distinct periodic characteristics with hysteresis for total water storage. For fully humid tropical catchments, hysteresis reveals a time invariant temporal delay from storage to runoff. Our spectral analysis supports the fact that the R‐S relationships can be characterized as a Linear Time Invariant (LTI) System. As a consequence in time domain an adjustment of time lag leads to correlation of 0.98 between runoff and storage. Based hereon, the hypothesis of a R‐S relationship characterized by the superposition of linear contributions from coupled/liquid storage and nonlinear contributions from uncoupled storages is investigated by means of remote sensing. For boreal catchments MODIS snow coverage is used to separate total storage into coupled/liquid and uncoupled/solid components either directly by assigning frozen solid storage to the snow‐covered areas or indirectly by a model‐based aggregation of snow and liquid according to snow coverage. Both methods show that the nonlinear part of the R‐S relationship can be fully assigned to the uncoupled/solid storage while the relationship of runoff and liquid storage can also be characterized as an LTI system. This system behavior thus allows for a direct determination of river runoff from GRACE mass and vice versa for unmanaged catchments, provided that the coupled/uncoupled storage components can be quantified remote sensing.

Published: April 2014

AbstractA series of α,β‐unsaturated iminium ions derived from substituted cinnamaldehydes and C2‐ and C5‐substituted chiral imidazolidin‐4‐ones were isolated and characterized in solution and in the solid state. The kinetics of the reactions of the iminium ions with silyl ketene acetals were determined in dichloromethane at 20 °C. The resulting second‐order rate constants were used to estimate the electrophilicity E of the iminium ions according to the linear free energy relationship log k2(20 °C)=sN(N+E). The kinetics for the reactions of two of the iminium ions with tributylphosphine were studied by laser flash spectroscopy and their second‐order rate constants were found to agree within a factor of 2.2 with those calculated by using the linear free energy relationship above.
Geminate Recombination as a Photoprotection Mechanism for Fluorescent Dyes
Authors: Holzmeister Phil , Gietl Andreas , Tinnefeld Philip 
Published: April 2014

AbstractDespite common presumption due to fast photodestruction pathways through higher excited states, we show that further improvement of photostability is still achievable with diffusion‐limited photoprotection formulas. Single‐molecule fluorescence spectroscopy reveals that thiolate ions effectively quench triplet states of dyes by photoinduced electron transfer. Interestingly, this reaction rarely yields a radical anion of the dye, but direct return to the ground state is promoted by an almost instantaneous back electron transfer (geminate recombination). This type of mechanism is not detected for commonly used reductants such as ascorbic acid and trolox. The mechanism avoids the formation of radical cations and improves the photostability of single fluorophores. We find that a combination of β‐mercaptoethanol and classical reducing and oxidizing systems yields the best results for several dyes including Atto532 and Alexa568.
Hydrocarbation of CC Bonds: Quantification of the Nucleophilic Reactivity of Ynamides
Authors: Laub Hans A. , Evano Gwilherm , Mayr Herbert 
Published: April 2014

AbstractDonor‐substituted diarylcarbenium ions Ar2CH+ react with ynamides to give 1‐amido‐substituted allyl cations (α,β‐unsaturated iminium ions). Kinetic studies show that these adducts, which correspond to the addition of a CH bond across the CC bond, are formed stepwise with initial formation of keteniminium ions and subsequent 1,3‐hydride shifts. The linear correlations between the second‐order rate constants (lg k2, 20 °C) with the electrophilicity parameters E of the diarylcarbenium ions allow us to include ynamides in our comprehensive nucleophilicity scale and thus predict potential electrophilic reaction partners.
The effect of silica addition on the microstructure and properties of polyethylene separators prepared by thermally induced phase separation
Authors: Zhang Chunjiang , Xia Yongfeng , Zuo Kaihui , Zeng Yu‐Ping 
Published: April 2014

ABSTRACTNovel composite polyethylene (PE) separators were prepared via thermally induced phase separation using SiO2 as the inorganic dopant and dioctyl phthalate as solvent. Through the control of silica content, the microstructure, thermal and crystalline properties, electrolyte uptake, thermal stability, and mechanical properties of the as‐prepared separators were investigated. The results showed that the doped silica particles favored the formation of the large pore size. The crystalline degree of PE was enhanced when doping silica in the ternary system below 3 wt %. The liquid electrolyte uptake was increased from 30.2% to 63.2% with doping silica content at 5 wt % in the mixed system, which benefits from the large pore size structure and the hydrophilicity of silica. The thermal decomposition temperature of the composite PE separators is 40°C higher than the pure PE separator due to the steric stabilization and the more stable space structure induced by the doped silica. The tensile strength was increased from 12 MPa to 13.3 MPa when doping 1 wt % silica, but decreased with further silica addition. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40724.
Changes in the distributions of freshwater mussels (Unionoida: Hyriidae) in coastal south‐eastern Australia and implications for their conservation status
Authors: Jones Hugh A. , Byrne Maria 
Published: April 2014

ABSTRACT

The conservation of freshwater mussels is neglected in Australia, and poor historical data may mask trends in species’ range and abundance. A combined‐evidence approach using published data, targeted surveys, historical records and a GIS‐based, reach‐scale measure of physical habitat quality was used to assess trends in the distributions of nine species in the south‐eastern coastal region.
Geomorphic impairment is widespread in upland and lowland streams, but not in rugged escarpment zones, with 16.8% of rivers in ‘poor’ geomorphic condition, 39.6% in ‘moderate’ condition and 43.6% of rivers in the region in ‘good’ condition.
Reductions of 44.4, 12.5 and 39.7% in site occupancy over the past 200 years were estimated for Hyridella depressa, Hyridella drapeta and Hyridella australis from logistic regression models of occupancy versus river geomorphic condition. Nonetheless, all species remain widely distributed and qualify as ‘least concern’ according to IUCN Red List criteria.
Hyridella narracanensis and Hyridella glenelgensis have fragmented or limited ranges and are vulnerable to threats, and both appear to meet IUCN Red List criteria for threatened species. The former species is listed as ‘data deficient’ but arguably should be ‘vulnerable’ as documented here. The latter species is not included on the IUCN Red List. Under the Australian EPBC Act (1999), H. narracanensis is not listed while H. glenelgensis is listed as ‘critically endangered’.
The Tasmanian endemic, Velesunio moretonicus, shows some evidence of decline but its population status is equivocal owing to the lack of monitoring data. It would qualify as ‘data deficient’. The three remaining species, Cucumerunio novaehollandiae, Alathyria profuga and Velesunio ambiguus are widely distributed and show no evidence of decline.
Additional surveys are needed to determine the current status and spatial distribution of freshwater mussel species in the region, and to establish baselines for future monitoring. Copyright © 2013 John Wiley & Sons, Ltd.
Force Control of a Cellular Tensegrity Structure with Model Uncertainties and Partial State Measurability
Authors: Zhou Shengfeng , Chen Peter C. Y. , Ong Chong‐Jin 
Published: April 2014

AbstractMechanical force is known to influence the behavior of biological cells. To study how external mechanical forces may affect cellular response and function necessitates the development of sophisticated force‐control techniques for accurate application of dynamical forces on living cells. In this paper, we develop a robust force control algorithm that enables accurate application of an external force on a dynamics model of biological cells. Such force control is achieved by utilizing a six‐strut cellular tensegrity model constructed based on the structural approach. Leveraging on the more comprehensive description of the nonlinearity and dynamic coupling of internal structural elements provided by this tensegrity model, we synthesize a novel robust control law that can effectively deal with model uncertainties and partial state measurability. Numerical simulations (involving forces of different dynamics profiles) are conducted to demonstrate the effectiveness of the proposal force control algorithm.
