The hybrids of styrene-butadiene-styrene tri-block copolymer (SBS) and amorphous poly(dl-lactic acid) (dl-PLA) are found to exhibit shape memory effects, which gives an example of a dual-domain shape memory system consisting of an elastic domain and a thermo-switch domain. The dual-domain manner in this hybrid is studied by means of differential scanning calorimetry (DSC) and scanning electron microscope (SEM). Subsequently, the tensile test clarifies the interactions of the two domains on shape memory effects. As an elastic domain, SBS offers good shape recovery when its content exceeds 50 wt%. As a thermo-switch domain, dl-PLA triggers the shape memory effect at ca. 55 °C and offers good shape fixing when the content exceeds 30 wt%. An easy-to-do and easy-to-know feature of the hybrid is that the optimization of shape memory effect can be achieved by generating bicontinous phases of SBS and dl-PLA, in which the dl-PLA content ranges from 30 to 70 wt%. -- Highlights: ► The composite materials of SBS and amorphous dl-PLA were prepared by blending. ► A continuous domain was observed with the increasing content of dl-PLA. ► The composites exhibited shape memory effects.

Interaction of GHz and MHz radiation with CO2 laser propagation in a silver halide fiber using sBs based phonon coupling is furthet investigated. The external signal serves to both probe and enhance laser generated sBs phonons in the fiber. Efficient coupling of microwave radiation into the fiber is accomplished by placing the fiber in a hollow metallic waveguide, designed and constructed to transmit the dominant mode in the 0.9-2.0 GHz band. MHz radiation is conveniently coupled into the fiber using the guided microwave radiation as carrier. Phonon emissions from the fiber under CO2 laser pumping are first established on a spectrum analyzer; low frequency generators ale then tuned to match these frequencies and their maximum interaction recorded. Such interactions are systematically studied by monitoring the amplitude and waveform of the reflected and transmitted laser pulse at various power levels and frequencies of the externally coupled radiation. A plot of reflected laser power versus incident laser power reveals a distinct sBs generated phonon threshold. Variouslaunch directions of the GHz and MHz radiation with respect to the direction of laser propagation are realized to verify theory governing sBs interactions. The MHz radiation and its associated phonons in the fiber are convenient tools for probing sBs related phenomenon in infrared fibers.

Full Text Available The worldwide trend toward using cheap, atoxic and durable materials from renewable resources contributes to sustainable development. Thus, the investigation of the potential use of vegetal fibers as reinforcing agent in polymeric composites has gained new significance. Sisal fiber has emerged as a reinforcing material for polymers used in automobile, footwear and civil industries. In this work, properties such as hardness, tensile strength and tear strength of polymer composites composed by block copolymer styrene-butadiene-styrene (SBS and 5, 10 and 20% by weight of sisal fiber were evaluated. The influence of conventional polymer processing techniques such as single-screw and double-screw extrusion, as well as the addition of coupling agent on the composite mechanical performance was investigated. Also, the morphology and thermal stability of the composites were analyzed. The addition of 2 wt. (% maleic anhydride as coupling agent between sisal fiber and SBS has improved the composite mechanical performance and the processing in a double-screw extruder has favored the sisal fiber distribution in the SBS matrix.

Gao, Junbo; Ding, Yingchun; Chen, Zhaoyang; Lin, Chengyou

2014-01-01

Chaotic stimulated Brillouin scattering (SBS) in optical fibers with weak external optical feedback has been investigated experimentally and theoretically. However, only the bifurcation route to chaos through period-one and quasi-periodic emission was discovered in the former work because the chaotic domain is very short in the general nonlinear system. In order to control the chaos process and observe finer periodic-orbit structures, a novel experiment was designed to extend the chaotic domain by using long optical fibers in the SBS system. In this experiment, the period-one, period-doubling, period-four and period-eight cycle routes to the chaos laser process as well as the more details of chaos, have been observed.

Improved slow-light performance of 10 Gb/s NRZ, PSBT and DPSK signals in fiber broadband SBS.

Yi, Lilin; Jaouen, Yves; Hu, Weisheng; Su, Yikai; Bigo, Sébastien

2007-12-10

We have demonstrated error-free operations of slow-light via stimulated Brillouin scattering (SBS) in optical fiber for 10-Gb/s signals with different modulation formats, including non-return-to-zero (NRZ), phase-shaped binary transmission (PSBT) and differential phase-shiftkeying (DPSK). The SBS gain bandwidth is broadened by using current noise modulation of the pump laser diode. The gain shape is simply controlled by the noise density function. Super-Gaussian noise modulation of the Brillouin pump allows a flat-top and sharp-edge SBS gain spectrum, which can reduce slow-light induced distortion in case of 10-Gb/s NRZ signal. The corresponding maximal delay-time with error-free operation is 35 ps. Then we propose the PSBT format to minimize distortions resulting from SBS filtering effect and dispersion accompanied with slow light because of its high spectral efficiency and strong dispersion tolerance. The sensitivity of the 10-Gb/s PSBT signal is 5.2 dB better than the NRZ case with a same 35-ps delay. The maximal delay of 51 ps with error-free operation has been achieved. Futhermore, the DPSK format is directly demodulated through a Gaussian-shaped SBS gain, which is achieved using Gaussian-noise modulation of the Brillouin pump. The maximal error-free time delay after demodulation of a 10-Gb/s DPSK signal is as high as 81.5 ps, which is the best demonstrated result for 10-Gb/s slow-light.

Composites of styrene-butadiene-styrene triblock copolymer (SBS) matrix with curauá fiber and/or a nanoparticulated mineral (montmorillonite clay - MMT) used as reinforcing agents were prepared by melt-mixing. The influence of clay addition on properties like tensile and tear strength, rebound resilience, flex fatigue life, abrasion loss, hardness and water absorption of composites with 5, 10 and 20 wt% of curauá fiber was evaluated in presence of maleic anhydride grafted styrene-(ethylene-co-butylene)-styrene triblock copolymer (MA-g-SEBS) coupling agent. Furthermore, the effect of mineral plasticizer loading on tensile strength of selected composites was investigated. The hybrid SBS composite that showed the best overall mechanical performance was composed by 2 wt% of MMT and 5 wt% of curauá fiber. Increasing fiber content up to 20 wt% resulted in a general decrease in all mechanical properties as well as incorporation of 5 wt% MMT caused a decrease in the tensile strength in all fiber contents. The hybrid composites showed clay agglomerates (tactoids) poorly dispersed that could explain the poor mechanical performance of composites at higher concentrations of curauá fiber and MMT nanoparticles. The addition of plasticizer further decreased the tensile strength while the addition of MMT nanoparticles decreased water absorption for all SBS composites. (author)

Geophysical Remote Sensing Using the HF Pumped Stimulated Brillouin Scatter (SBS) Emission Lines Produced by HAARP

Science.gov (United States)

Bernhardt, P. A.; Selcher, C. A.

2009-12-01

An ordinary or extraordinary mode electromagnetic wave can decay into a low frequency electrostatic wave and a scattered electromagnetic wave by a process called stimulated Brillouin scatter (SBS). The low frequency wave can be either an ion acoustic wave (IA) or an electrostatic ion cyclotron (EIC) wave. The first detection ion acoustic waves by this process during ionospheric modification with high power radio waves was reported by Norin et al. (2009) using the HAARP transmitter in Alaska. The first detection of the electrostatic ion cyclotron waves is reported here using HAARP during the March 2009 campaign. Subsequent experiments have provided additional verification of the SBS process and quantitative interpretation of the scattered wave frequency offsets to yield measurements of the electron temperatures in the heated ionosphere by Bernhardt et al. (2009). Using the SBS technique to generate ion acoustic waves, electron temperatures between 3000 and 4000 K were measured over the HAARP facility. The matching conditions for decay of the high frequency pump wave show that in addition to the production of an ion-acoustic wave, an electrostatic ion cyclotron wave can produced by the generalized SBS processes only if the pump waves makes a large angle with the magnetic field. When the EIC mode is produced, it is seen as a narrow of stimulated electromagnetic emissions at the ion cyclotron frequency. Occasionally, multiple lines are seen and analyzed to yield the relative abundance of oxygen, and molecular ions in the lower ionosphere. This ion mass spectrometer interpretation of the SBS data is new to the field of ionosphere remote sensing. In addition, based on the matching condition theory, the first profiles of the scattered wave amplitude are produced using the stimulated Brillouin scatter (SBS) matching conditions. These profiles are consistent with maximum ionospheric interactions at the upper-hybrid resonance height and at a region just below the plasma

2015-07-09

The photoinduced intramolecular excited-state energy-transfer (EET) process in conjugated polymers has received a great deal of research interest because of its important role in the light harvesting and energy transport of organic photovoltaic materials in photoelectric devices. In this work, the silylene-bridged biphenyl and stilbene (SBS) system was chosen as a simplified model system to obtain physical insight into the photoinduced intramolecular energy transfer between the different building units of the SBS copolymer. In the SBS system, the vinylbiphenyl and vinylstilbene moieties serve as the donor (D) unit and the acceptor (A) unit, respectively. The ultrafast excited-state dynamics of the SBS system was investigated from the point of view of nonadiabatic dynamics with the surface-hopping method at the TDDFT level. The first two excited states (S1 and S2) are characterized by local excitations at the acceptor (vinylstilbene) and donor (vinylbiphenyl) units, respectively. Ultrafast S2-S1 decay is responsible for the intramolecular D-A excitonic energy transfer. The geometric distortion of the D moiety play an essential role in this EET process, whereas the A moiety remains unchanged during the nonadiabatic dynamics simulation. The present work provides a direct dynamical approach to understand the ultrafast intramolecular energy-transfer dynamics in SBS copolymers and other similar organic photovoltaic copolymers.

Full Text Available Asphalt mixture is susceptible to moisture damage under the effect of freeze-thaw (F-T cycles. In this paper, crumb rubber (CR was used to modify stone mastic asphalt (SMA and the effects of diatomite and styrene butadiene styrene (SBS on antifreezing performances of crumb rubber modified SMA (CRSMA were investigated. Regression analysis and modified grey model (MGM were used to construct the prediction models for properties of modified mixtures. CRSMA, CR and diatomite modified SMA (CRDSMA, and CR and SBS modified SMA (CRSSMA were prepared in laboratory, respectively. Process of F-T cycles was designed. Air void, indirect tensile strength (ITS, and indirect tensile stiffness modulus (ITSM were measured to evaluate the antifreezing performances of CRSMA, CRDSMA, and CRSSMA. Results indicate that air voids increase with the increasing of F-T cycles. ITS and ITSM all decrease with the increasing of F-T cycles. The addition of diatomite and SBS can reduce the air void and improve the ITS and ITSM of CRSMA. CRSSMA presents the lowest air void, highest tensile strength, and largest stiffness modulus, which reveals that CRSSMA has the best F-T resistance among three different kinds of mixtures. Moreover, MGM (1, 2 models present more favorable accuracy in prediction of air void and ITS compared with regression ones.

Pump spectral linewidth influence on stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS) and self-termination behavior of SRS in liquids

2016-12-15

The threshold, temporal behavior, and conversion efficiency of stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SBS) in three liquids (benzene, hexane, and dimethyl sulfoxide) and two crystals (calcite and barium nitrate) have been investigated under three largely different spectral linewidth conditions. Pumped with 532-nm and nanosecond duration laser pulses of ≤ 0.01 cm{sup -1} linewidth, only SBS can be generated in all tested liquids with a high nonlinear reflectivity. However when the pump spectral linewidth is ∝0.07 cm{sup -1} or ∝0.8 cm{sup -1}, both SBS and SRS can be observed in benzene while only SRS can be generated in dimethyl sulfoxide; in all these cases SRS is the dominant contribution to the stimulated scattering but the efficiency values are drastically decreased due to the self-termination behavior of SRS in liquids, which arises from the thermal self-defocusing of both pump beam and SRS beam owing to Stokes-shift related opto-heating effect. In contrast, for SRS process in the two crystals, the thermal self-defocusing influence is negligible benefitting from their much greater thermal conductivity, and a higher conversion efficiency of SRS generation can be retained under all three pump conditions.

SBS pulse compression for excimer inertial fusion energy drivers

International Nuclear Information System (INIS)

Linford, G.J.

1994-01-01

A key requirement for the development of commercial fusion power plants utilizing inertial confinement fusion (ICF) as a source of thermonuclear power is the availability of reliable, efficient laser drivers. These laser drivers must be capable of delivering UV optical pulses having energies of the order of 5MJ to cryogenic deuterium-tritium (D/T) ICF targets. The current requirements for laser ICF target irradiation specify the laser wavelength, λ ca. 250 nm, pulse duration, τ p ca. 6 ns, bandwidth, Δλ ca. 0.1 nm, polarization state, etc. Excimer lasers are a leading candidate to fill these demanding ICF driver requirements. However, since excimer lasers are not storage lasers, the excimer laser pulse duration, τ pp , is determined primarily by the length of the excitation pulse delivered to the excimer laser amplifier. Pulsed power associated with efficiently generating excimer laser pulses has a time constant, τ pp which falls in the range, 30 τ p pp p . As a consequence, pulse compression is needed to convert the long excimer laser pulses to pulses of duration τ p . These main ICF driver pulses require, in addition, longer, lower power precursor pulses delivered to the ICF target before the arrival of the main pulse. Although both linear and non-linear optical (NLO) pulse compression techniques have been developed, computer simulations have shown that a ''chirped,'' self-seeded, stimulated Brillouin scattering (SBS) pulse compressor cell using SF 6 at a density, ρ ca. 1 amagat can efficiently compress krypton fluoride (KrF) laser pulses at λ=248 nm. In order to avoid the generation of output pulses substantially shorter than τ p , the optical power in the chirped input SBS ''seed'' beams was ramped. Compressed pulse conversion efficiencies of up to 68% were calculated for output pulse durations of τ p ca. ns

Elimination of the reactivation process in the adhesion of chlorinated SBS rubber with polychloroprene adhesives

2007-04-01

Full Text Available Chlorination treatment of a thermoplastic styrene-butadiene-styrene rubber (SBS with a 3 wt% solution of trichloroisocyanuric acid (TCI in methyl ethyl ketone (MEK introduces chlorinated and oxidized moieties on the rubber surface which increase its surface energy and produces surface microroughness. Consequently adhesion properties, evaluated by T-peel strength measurements in chlorinated SBS/solvent based-polyurethane adhesive/leather joints, are enhanced. In this study, two solvent-based polychloroprene adhesives (PCP0 and PCP30R have been considered as an alternative to the commonly used solvent-based polyurethane adhesive (PU. A thermoreactive phenolic resin was added to one of the polychloroprene adhesive formulations (PCP30R. This tackifier resin favors chlorination of the adhesive and reinforces the interface between the chlorinated adhesive and the chlorinated rubber surface. Besides, PCP30R adhesive does not need adhesive reactivation and considerable high T-peel strength value (5.7±0.3 kN/m was obtained. Elimination of the reactivation process implies a considerable improvement of the manufacturing process in the footwear industry.

A key requirement for the development of commercial fusion power plants utilizing inertial confinement fusion (ICF) as a source of thermonuclear power is the availability of reliable, efficient laser drivers. These laser drivers must be capable of delivering UV optical pulses having energies of the order of 5MJ to cryogenic deuterium-tritium (D/T) ICF targets. The current requirements for laser ICF target irradiation specify the laser wavelength, {lambda} ca. 250 nm, pulse duration, {tau}{sub p} ca. 6 ns, bandwidth, {Delta}{lambda} ca. 0.1 nm, polarization state, etc. Excimer lasers are a leading candidate to fill these demanding ICF driver requirements. However, since excimer lasers are not storage lasers, the excimer laser pulse duration, {tau}{sub pp}, is determined primarily by the length of the excitation pulse delivered to the excimer laser amplifier. Pulsed power associated with efficiently generating excimer laser pulses has a time constant, {tau}{sub pp} which falls in the range, 30 {tau}{sub p}<{tau}{sub pp}<100{tau}{sub p}. As a consequence, pulse compression is needed to convert the long excimer laser pulses to pulses of duration {tau}{sub p}. These main ICF driver pulses require, in addition, longer, lower power precursor pulses delivered to the ICF target before the arrival of the main pulse. Although both linear and non-linear optical (NLO) pulse compression techniques have been developed, computer simulations have shown that a ``chirped,`` self-seeded, stimulated Brillouin scattering (SBS) pulse compressor cell using SF{sub 6} at a density, {rho} ca. 1 amagat can efficiently compress krypton fluoride (KrF) laser pulses at {lambda}=248 nm. In order to avoid the generation of output pulses substantially shorter than {tau}{sub p}, the optical power in the chirped input SBS ``seed`` beams was ramped. Compressed pulse conversion efficiencies of up to 68% were calculated for output pulse durations of {tau}{sub p} ca. ns.

Experimental data are presented on a solid-state ring laser with an SBS mirror in the case of the initiation of stimulated emission by a series of pulses 200-300 ns in duration at a wavelength of 1.06 micron. It is shown that this laser can be suitable for the development of a laser source with radiation parameters (energy and transverse and temporal structure) that are controlled by an external signal. It is also suitable for the development of a low-threshold phase-conjugating mirror. 5 refs.

Using the method of four-wave probing of the waist of the laser beam focused into the bulk of a short active medium (L ll τc, where L is the length of the active medium, τ is the pulse duration, and c is the speed of light), we have studied the dynamics of the behaviour of a dark soliton, appearing upon a jump of the input Stokes signal phase by about π under SBS. The computer simulation has shown that when spontaneous noises with the gain increment Γ, exceeding the self-reflection threshold by 2 - 3 times, are generated, the dark soliton propagates along the interaction region for the time t ≈ T2Γth/2, where T2 is the the lifetime of acoustic phonons, and Γth = 25 - 30 is the stationary threshold gain increment.

We present a comprehensive analysis of the technique of Longitudinal-Mode-Filling (LMF) to reduce Stimulated Brillouin Scattering (SBS) limitations in Ytterbium Doped Fibre Amplifiers (YDFA), for the generation of nanosecond, temporally shaped pulses. A basic Master-Oscillator-Power-Amplifier (MOPA) system, comprising an output YDFA with 10 μm-core active fibre, is experienced for benchmarking purposes. Input pulse-shaping is operated thanks to direct current modulation in highly multimode laser-diode seeds, either based on the use of Distributed Feed-Back (DFB) or of a Fibre Bragg Grating (FBG). These seeds enable wavelength control. We verify the effectiveness of the combination of LMF, with appropriate mode spacing, in combination with natural chirp effects from the seed to control the SBS threshold in a broad range of output energies, from a few to some tens of μJ. These variations are discussed versus all the parameters of the laser system. In accordance with the proposal of a couple of basic principles and with the addition of gain saturation effects along the active fibre, we develop a full-vectorial numerical model. Fine fits between experimental results and theoretical expectations are demonstrated. The only limitation of the technique arises from broadband beating noise, which is analysed thanks to a simplified, but fully representative description to discuss the signal-to-noise ratio of the amplified pulses. This provides efficient tools for application to the design of robust and cost-effective MOPAs, aiming to the generation of finely shaped and energetic nanosecond pulses without the need for any additional electro-optics.

The aim was to develop a new model to identify residential buildings with higher frequencies of "SBS" than expected, "risk buildings". In 2005, 481 multi-family buildings with 10,506 dwellings in Stockholm were studied by a new stratified random sampling. A standardised self-administered questionnaire was used to assess "SBS", atopy and personal factors. The response rate was 73%. Statistical analysis was performed by multiple logistic regressions. Dwellers owning their building reported less "SBS" than those renting. There was a strong relationship between socio-economic factors and ownership. The regression model, ended up with high explanatory values for age, gender, atopy and ownership. Applying our model, 9% of all residential buildings in Stockholm were classified as "risk buildings" with the highest proportion in houses built 1961-1975 (26%) and lowest in houses built 1985-1990 (4%). To identify "risk buildings", it is necessary to adjust for ownership and population characteristics.

Compression of pulsed Nd : glass laser radiation under stimulated Brillouin scattering (SBS) in perfluorooctane is investigated. Compression of 16-ns pulses at a beam diameter of 30 mm is implemented. The maximum compression coefficient is 28 in the optimal range of laser pulse energies from 2 to 4 J. The Stokes pulse power exceeds that of the initial laser pulse by a factor of about 11.5. The Stokes pulse jitter (fluctuations of the Stokes pulse exit time from the compressor) is studied. The rms spread of these fluctuations is found to be 0.85 ns.

The preparation and characterization of new, tailor-made polymeric membranes using poly(styrene-b-butadiene-b-styrene) (SBS) triblock copolymers for gas separation are reported. Structural differences in the copolymer membranes, obtained by manipulation of the self-assembly of the block copolymers in solution, are characterized using atomic force microscopy, transmission electron microscopy, and the transport properties of three gases (CO{sub 2}, N{sub 2}, and CH{sub 4}). The CH{sub 4}/N{sub 2} ideal selectivity of 7.2, the highest value ever reported for block copolymers, with CH{sub 4} permeability of 41 Barrer, is obtained with a membrane containing the higher amount of polybutadiene (79 wt%) and characterized by a hexagonal array of columnar polystyrene cylinders normal to the membrane surface. Membranes with such a high separation factor are able to ease the exploitation of natural gas with high N{sub 2} content. The CO{sub 2}/N{sub 2} ideal selectivity of 50, coupled with a CO{sub 2} permeability of 289 Barrer, makes SBS a good candidate for the preparation of membranes for the post-combustion capture of carbon dioxide.

There are few studies on sick building syndrome (SBS) including clinical measurements for atopy and fractional exhaled nitric oxide (FeNO). Our aim was to study associations between SBS symptoms, selected personal factors, office characteristics and indoor office exposures among office workers from a university in Malaysia. Health data were collected by a questionnaire (n=695), skin prick test (SPT) (n=463) and FeNO test (n=460). Office settled dust was vacuumed and analyzed for endotoxin, (1,3)-β-glucan and house dust mites (HDM) allergens group 1 namely Dermatophagoides pteronyssinus (Der p 1) and Dermatophagoides farinae (Der f 1). Office indoor temperature, relative air humidity (RH), carbon monoxide (CO) and carbon dioxide (CO2) were measured by a direct reading instrument. Associations were studied by two-levels multiple logistic regression with mutual adjustment and stratified analysis. The prevalence of weekly dermal, mucosal and general symptoms was 11.9%, 16.0% and 23.0% respectively. A combination of SPT positivity (allergy to HDM or cat) and high FeNO level (≥25 ppb) was associated with dermal (p=0.002), mucosal (p<0.001) and general symptoms (p=0.05). Der f1 level in dust was associated with dermal (p<0.001), mucosal (p<0.001) and general (p=0.02) symptoms. Among those with allergy to D. farinae, associations were found between Der f 1 levels in dust and dermal (p=0.003), mucosal (p=0.001) and general symptoms (p=0.007). Office-related symptoms were associated with Der f 1 levels in dust (p=0.02), low relative air humidity (p=0.04) and high office temperature (p=0.05). In conclusion, a combination of allergy to cat or HDM and high FeNO is a risk factor for SBS symptoms. Der f 1 allergen in dust can be a risk factor for SBS in the office environment, particularly among those sensitized to Der f 1 allergen. Copyright © 2015 Elsevier B.V. All rights reserved.

Data on the prevalence of social disablement in long-stay psychiatric patients, and the assessment of the psychometric properties of the instruments that evaluate social behaviour in this population are scarce in Brazil. Therefore, this cross-sectional study aimed to estimate the prevalence rates of social disablement in a population of long-stay psychiatric patients from the Rio de Janeiro metropolitan area, and assessed the psychometric properties of the Social Behaviour Schedule (SBS). Data were collected from a population of 881 psychiatric patients housed in the Municipal Mental Health Institute using the 21-item SBS. Most of the patients were women (59%), the mean age was 65.8 years (SD = 11) and the mean length of stay was 37.3 years (SD = 11.5). Of the population, 50.6% were scored as having poor self-care, 46% with little spontaneous communication, 41.1% with poor attention span, and 37.1% with underactivity. Comparing our data with international studies that used the same instrument, we found that our population was more disabled than the others, especially on the social withdrawal factor. Regarding psychometric properties, the inter-rater kappa was 0.709, the inter-informant kappa was 0.500, and the Cronbach's alpha coefficient was 0.766. The groups of patients in the six settings of the institute presented significant statistical differences in the total score (F = 11.447, p < 0.001). This study demonstrates the high rates of social disablement in this population. The precarious conditions of the institution where the patients have been living for decades and unmet individual care may have exacerbated their social disablement. Furthermore, the SBS-BR had satisfactory psychometric properties, particularly reliability, showing it to be an adequate instrument for measuring social disablement in Brazil.

Sick building syndrome (SBS) and exposure to water-damaged buildings: time series study, clinical trial and mechanisms.

Science.gov (United States)

Shoemaker, Ritchie C; House, Dennis E

2006-01-01

Occupants of water-damaged buildings (WDBs) with evidence of microbial amplification often describe a syndrome involving multiple organ systems, commonly referred to as "sick building syndrome" (SBS), following chronic exposure to the indoor air. Studies have demonstrated that the indoor air of WDBs often contains a complex mixture of fungi, mycotoxins, bacteria, endotoxins, antigens, lipopolysaccharides, and biologically produced volatile compounds. A case-series study with medical assessments at five time points was conducted to characterize the syndrome after a double-blinded, placebo-controlled clinical trial conducted among a group of study participants investigated the efficacy of cholestyramine (CSM) therapy. The general hypothesis of the time series study was that chronic exposure to the indoor air of WDBs is associated with SBS. Consecutive clinical patients were screened for diagnosis of SBS using criteria of exposure potential, symptoms involving at least five organ systems, and the absence of confounding factors. Twenty-eight cases signed voluntary consent forms for participation in the time-series study and provided samples of microbial contaminants from water-damaged areas in the buildings they occupied. Twenty-six participants with a group-mean duration of illness of 11 months completed examinations at all five study time points. Thirteen of those participants also agreed to complete a double-blinded, placebo-controlled clinical trial. Data from Time Point 1 indicated a group-mean of 23 out of 37 symptoms evaluated; and visual contrast sensitivity (VCS), an indicator of neurological function, was abnormally low in all participants. Measurements of matrix metalloproteinase 9 (MMP9), leptin, alpha melanocyte stimulating hormone (MSH), vascular endothelial growth factor (VEGF), immunoglobulin E (IgE), and pulmonary function were abnormal in 22, 13, 25, 14, 1, and 7 participants, respectively.

Influence of SEBS-MA and SBS compatibilizers on properties and morphology of blends of polystyrene/rubber residue (SBRr from the footwear industry

Directory of Open Access Journals (Sweden)

Carlos Bruno Barreto Luna

Full Text Available Abstract The reuse of rubber waste is very important today, both to reduce the harmful effects on the environment, and to reduce the cost of new material development. Considering that most of the studies reported in literature refer to the reuse of tire waste, this article aims to evaluate the influence of styrene-butadiene-styrene (SBS and styrene-(ethylene-butylene-styrene grafted with maleic anhydride (SEBS-MA compatibilizers on the blend performance of polystyrene (PS/styrene-butadiene rubber residue (SBRr, which come from the footwear industry. The blends were prepared in a co-rotating twin screw extruder and then were molded by injection. They were analyzed by impact and tensile tests, heat deflection temperature (HDT, ductile-brittle transition temperature, dynamic mechanical thermal analysis (DMTA and transmission electron microscopy (TEM. The results evidenced that the use of any of the compatibilizers on the PS/SBRr blend significantly increased the impact strength, while the tensile properties and HDT were lower when compared to the polymer matrix. The ductile-brittle transition temperature remains at approximately 25°C range for all the blends. In general, it has been proved that the SBS was the most effective compatibilization process in the PS/SBRr system. The DMTA test shows the presence of two distinct temperature peaks. The morphologies obtained by TEM of binary and ternary blends were quite different and typical of immiscible blend. The results show a good perspective regarding the use of industrial waste (SBRr, since it may enhance a material that would be discarded.

Loss of significant intestinal length from congenital anomaly or disease may lead to short bowel syndrome (SBS); intestinal failure may be partially offset by a gain in epithelial surface area, termed adaptation. Current in vivo models of SBS are costly and technically challenging. Operative times and survival rates have slowed extension to transgenic models. We created a new reproducible in vivo model of SBS in zebrafish, a tractable vertebrate model, to facilitate investigation of the mechanisms of intestinal adaptation. Proximal intestinal diversion at segment 1 (S1, equivalent to jejunum) was performed in adult male zebrafish. SBS fish emptied distal intestinal contents via stoma as in the human disease. After 2 wk, S1 was dilated compared with controls and villus ridges had increased complexity, contributing to greater villus epithelial perimeter. The number of intervillus pockets, the intestinal stem cell zone of the zebrafish increased and contained a higher number of bromodeoxyuridine (BrdU)-labeled cells after 2 wk of SBS. Egf receptor and a subset of its ligands, also drivers of adaptation, were upregulated in SBS fish. Igf has been reported as a driver of intestinal adaptation in other animal models, and SBS fish exposed to a pharmacological inhibitor of the Igf receptor failed to demonstrate signs of intestinal adaptation, such as increased inner epithelial perimeter and BrdU incorporation. We describe a technically feasible model of human SBS in the zebrafish, a faster and less expensive tool to investigate intestinal stem cell plasticity as well as the mechanisms that drive intestinal adaptation.

This study involved evaporation of the radioactive low activity waste AN-104 pretreated waste and a simulant LAW submerged bed scrubber recycle from Duratek blended at two different volume ratios. The AN104SBS35651 pretreated wastes were then blended with glass former chemicals, GFCs, and a single blend vitrified. The chemical and physical properties, during all phases of blending were characterized per Table 1-1. The AN-104 radioactive waste used for this study was initially characterized at SRNL, Hay 2003, followed by filtration to remove entrained solids, Poirier 2003, and put through ion exchange for cesium removal, Adu-Wusu 2003,. All the test objectives in Table 1-1 are from section 3 of the Test Specification, Sidibe 2003. The test exception listed in Table 1-2 deleted the vitrification objectives for vitrification product analyses and product testing of the AN-104 glass. Therefore, Table 1-1 does not list any vitrification product analyses and product testing objectives

Simulations of drastically reduced SBS with laser pulses composed of a Spike Train of Uneven Duration and Delay (STUD pulses)

International Nuclear Information System (INIS)

Hueller, S.; Afeyan, B.

2013-01-01

By comparing the impact of established laser smoothing techniques like Random Phase Plates (RPP) and Smoothing by Spectral Dispersion (SSD) to the concept of 'Spike Trains of Uneven Duration and Delay' (STUD pulses) on the amplification of parametric instabilities in laser-produced plasmas, we show with the help of numerical simulations, that STUD pulses can drastically reduce instability growth by orders of magnitude. The simulation results, obtained with the code Harmony in a nonuniformly flowing mm-size plasma for the Stimulated Brillouin Scattering (SBS) instability, show that the efficiency of the STUD pulse technique is due to the fact that successive re-amplification in space and time of parametrically excited plasma waves inside laser hot spots is minimized. An overall mean fluctuation level of ion acoustic waves at low amplitude is established because of the frequent change of the speckle pattern in successive spikes. This level stays orders of magnitude below the levels of ion acoustic waves excited in hot spots of RPP and SSD laser beams. (authors)

To assess the feasibility of using a novel form of multichannel electrical stimulation, termed Sensory Barrage Stimulation (SBS) for the treatment of spasticity affecting the elbow flexor muscles and to compare this with conventional single-channel TENS stimulation. Altogether ten participants with spasticity of the flexor muscles of the elbow of Grade 2 or above on the Modified Ashworth Scale (MAS) were recruited to this crossover double blind randomized trial. The participants received two intervention sessions (SBS and TENS), one week apart in a randomized order. Both interventions were applied over the triceps brachii on the affected arm for a duration of 60 minutes. Spasticity was measured using the MAS. Secondary outcome measures were self-reported change in spasticity, measured on a visual analog scale (VAS, 0-100), and therapist-rated strength of elbow extension and strength of elbow flexion. Measurements were taken immediately before each intervention was applied, immediately after the intervention, and one hour after the intervention. Immediately after stimulation spasticity showed a significant reduction for both TENS and SBS groups assessed by MAS -0.9 ± 0.2 vs. -1.1 ± 0.2 and by VAS -15 ± 3 vs. -31 ± 8. For SBS this improvement in MAS was still present at one hour after the stimulation, but not for TENS. Altogether seven SBS responders and four TENS responders were identified. This study demonstrates the feasibility and practicality of applying the new concept of SBS. Promising results indicate it causes a reduction in spasticity. © 2015 International Neuromodulation Society.

The aim was to investigate the value of virtual planning (VP) based on preoperative magnetic resonance imaging (MRI) for surgical planning in SBS and to compare the effects of virtual planning with 3D contours between the expert and the surgeon in training. Retrospective analysis. Twelve patients with manually segmented anatomical structures based on preoperative MRI were evaluated by eight surgeons in a randomized order using a validated National Aeronautics and Space Administration Task Load Index (NASA-TLX) questionnaire. Multivariate analysis revealed significant reduction of workload when using VP (PNASA-TLX differences (P.05). Preoperative anatomical segmentation with virtual surgical planning using contours in endoscopic SBS significantly reduces the workload for the expert and the surgeon in training.

This study assessed the effect of pretreatment of hybrid and glass ceramics using a self-etching primer on the shear bond strength (SBS) and surface topography, in comparison to pretreatment with hydrofluoric acid and silane. 40 rectangular discs from each ceramic material (IPS e.max CAD;EM, Vita Mark II;VM, Vita Enamic;VE), were equally divided (n=10) and assigned to one of four surface pretreatment methods; etching with 4.8% hydrofluoric acid followed by Monobond plus (HFMP), Monobond etch & prime (Ivoclar Vivadent) (MEP), No treatment (NT) as negative control and Monobond plus (Ivoclar Vivadent) with no etching (MP) as positive control. SBS of resin cement (Multilink-N, Ivoclar Vivadent) to ceramic surfaces was tested following a standard protocol. Surface roughness was evaluated using an Atomic force microscope (AFM). Surface topography and elemental analysis were analyzed using SEM/EDX. Data were analyzed with two-way analysis of variance (ANOVA) and post-hoc Bonferroni test at a significance level of α=0.05. Pretreatment with HFMP resulted in higher SBS and increased surface roughness in comparison to MEP and MP. Regardless the method of surface pretreatment, the mean SBS values of EM ceramic was significantly higher (pceramics for resin-luting cementation. Copyright © 2017 Japan Prosthodontic Society.

A laser system, such as a master oscillator/power amplifier system, comprises a gain medium and a stimulated Brillouin scattering SBS mirror system. The SBS mirror system includes an in situ filtered SBS medium that comprises a compound having a small negative non-linear index of refraction, such as a perfluoro compound. An SBS relay telescope having a telescope focal point includes a baffle at the telescope focal point which blocks off angle beams. A beam splitter is placed between the SBS mirror system and the SBS relay telescope, directing a fraction of the beam to an alternate beam path for an alignment fiducial. The SBS mirror system has a collimated SBS cell and a focused SBS cell. An adjustable attenuator is placed between the collimated SBS cell and the focused SBS cell, by which pulse width of the reflected beam can be adjusted.

Some polysaccharide processing enzymes possess secondary carbohydrate binding sites situated on the surface far from the active site. In barley alpha-amylase 1 (AMY1), two such sites, SBS1 and SBS2, are found on the catalytic (beta/alpha)(8)-barrel and the noncatalytic C-terminal domain, respectively. Site-directed mutagenesis of Trp(278) and Trp(279), stacking onto adjacent ligand glucosyl residues at SBS1, and of Tyr(380) and His(395), making numerous ligand contacts at SBS2, suggested that SBS1 and SBS2 act synergistically in degradation of starch granules. While SBS1 makes the major contribution to binding and hydrolysis of starch granules, SBS2 exhibits a higher affinity for the starch mimic beta-cyclodextrin. Compared to that of wild-type AMY1, the K(d) of starch granule binding by the SBS1 W278A, W279A, and W278A/W279A mutants thus increased 15-35 times; furthermore, the k(cat)/K(m) of W278A/W279A was 2%, whereas both affinity and activity for Y380A at SBS2 were 10% of the wild-type values. Dual site double and triple SBS1/SBS2 substitutions eliminated binding to starch granules, and the k(cat)/K(m) of W278A/W279A/Y380A AMY1 was only 0.4% of the wild-type value. Surface plasmon resonance analysis of mutants showed that beta-cyclodextrin binds to SBS2 and SBS1 with K(d,1) and K(d,2) values of 0.07 and 1.40 mM, respectively. A model that accounts for the observed synergy in starch hydrolysis, where SBS1 and SBS2 bind ordered and free alpha-glucan chains, respectively, thus targeting the enzyme to single alpha-glucan chains accessible for hydrolysis, is proposed. SBS1 and SBS2 also influence the kinetics of hydrolysis for amylose and maltooligosaccharides, the degree of multiple attack on amylose, and subsite binding energies.

Parenteral nutrition (PN) provides nutrition intravenously; however, this life-saving therapy is associated with significant liver disease. Recent evidence indicates improvement in PN-associated injury in animals with intact gut treated with enteral bile acid (BA), chenodeoxycholic acid (CDCA), and a gut farnesoid X receptor (FXR) agonist, which drives the gut-liver cross talk (GLCT). We hypothesized that similar improvement could be translated in animals with short bowel syndrome (SBS). Using piglets, we developed a novel 90% gut-resected SBS model. Fifteen SBS piglets receiving PN were given CDCA or control (vehicle control) for 2 weeks. Tissue and serum were analyzed posteuthanasia. CDCA increased gut FXR (quantitative polymerase chain reaction; P = .008), but not downstream FXR targets. No difference in gut fibroblast growth factor 19 (FGF19; P = .28) or hepatic FXR (P = .75), FGF19 (P = .86), FGFR4 (P = .53), or Cholesterol 7 α-hydroxylase (P = .61) was noted. PN resulted in cholestasis; however, no improvement was noted with CDCA. Hepatic fibrosis or immunostaining for Ki67, CD3, or Cytokeratin 7 was not different with CDCA. PN resulted in gut atrophy. CDCA preserved (P = .04 vs control) gut mass and villous/crypt ratio. The median (interquartile range) for gut mass for control was 0.28 (0.17-0.34) and for CDCA was 0.33 (0.26-0.46). We note that, unlike in animals with intact gut, in an SBS animal model there is inadequate CDCA-induced activation of gut-derived signaling to cause liver improvement. Thus, it appears that activation of GLCT is critically dependent on the presence of adequate gut. This is clinically relevant because it suggests that BA therapy may not be as effective for patients with SBS. © 2018 American Society for Parenteral and Enteral Nutrition.

An extracellular phytase of Aspergillus oryzae SBS50 was purified to homogeneity using ammonium sulphate precipitation, ion-exchange and gel filtration chromatography. Purified phytase has a monomeric molecular mass of ∼80kDa exhibiting its optimal activity at pH 5.0 and 50°C with a T 1/2 of 300min at 50°C. Phytase of A. oryzae displayed broad substrate specificity with V max and K m values of 58.82μmol/ml/min and 1.14mM, respectively, for calcium phytate. Purity and homogeneity of the phytase was confirmed by high performance liquid chromatography and MALDI-TOF analysis revealed the identification of a peptide showing homology with acid phosphatase of Aspergillus oryzae RIB40. Among the inhibitors, 2,3-butanedione and sodium molybdate significantly inhibited the enzyme activity. Phytase of A. oryzae showed protease-resistance and was more stable during storage at 4°C and -20°C as compared to room temperature. Among all the feed samples, mustard oil cake was dephytinized more efficiently than other feed samples. These unique properties suggested that the phytase has the potential to be useful as an animal feed supplement. Copyright © 2017 Elsevier B.V. All rights reserved.

Highlights: • The c-SBS films were prepared using a gamma ray or electron beam. • The crosslinking degree of the c-SBS films were increased with the irradiation dose. • The prepared c-SBS films were sulfonated with various concentration of CSA. • The sulfonation of the c-SBS film is largely dependent on the concentration of CSA. • The sulfonation process is progressed from the surface to the inner part of c-SBS film. -- Abstract: Several crosslinked poly(styrene–butadiene–styrene) (c-SBS) block copolymer films were prepared using a gamma ray or electron beam with various irradiation doses and the prepared c-SBS film was then subjected to sulfonation using a chlorosulfonic acid (CSA) solution to introduce a sulfonic acid group. To estimate the degree of crosslinking, the gel fractions and FT-IR spectra of the c-SBS films were used and the results indicate that the degree of crosslinking is increased with an increase in the radiation dose. The surface morphology and mechanical property of the c-SBS films were observed using SEM and UTM instruments, respectively. The sulfonated c-SBS films were investigated by measuring the ion exchange capacity (IEC) and by observing the cross-sectional distribution patterns of sulfonic acid group using an SEM-EDX instrument. The IEC and SEM-EDX studies indicate that the sulfonated c-SBS membranes can be successfully prepared through the radiation crosslinking of the SBS film and the subsequent sulfonation with a diluted CSA solution.

Nurses' Perceptions of Barriers and Facilitators Affecting the Shaken Baby Syndrome Education Initiative: An Exploratory Study of a Massachusetts Public Policy.

Rideout, Leslie

2016-01-01

The objective of this study was to assess nurses' perceptions of barriers to and facilitators of implementation of the shaken baby syndrome (SBS)/abusive head trauma (AHT) public policy. A legislative Act providing for the prevention of SBS/AHT was passed in Massachusetts in November 2006. A stipulation of this Act was the provision of a program to educate parents/guardians of newborns about SBS/AHT prevention. A quantitative, cross-sectional research design with a qualitative component was used for this study. Nurses in 13 Massachusetts birthing hospitals were surveyed using a Web-based questionnaire (hosted by Qualtrics, Provo, Utah). Hospital nurses' responses (N = ∼ 922; 155 responded) revealed barriers to and facilitators of SBS/AHT guideline implementation. The disadvantage of Web-based surveys as they relate to the challenges of enlisting cooperation and a lack of direct access to the nurses may have attributed to the low response rate (17%) for this study. The outcomes of logistic regression analyses and themes from the qualitative analysis revealed a lack of SBS/AHT brochures and an inability to provide SBS/AHT education for non-English-speaking parents/guardians as barriers to SBS/AHT education. An atmosphere of supportive leadership facilitated implementation of the SBS/AHT education guidelines by nurses. It is imperative that nurse leadership support be sustained so that nurses have SBS/AHT education resources, an understanding of the SBS/AHT education guidelines, and feedback about the impact of their SBS/AHT education interventions.

Full Text Available This article briefly discusses various definitions and concepts of the so-called information society. The term information society has been proposed to refer to the post-industrial society in which information plays a pivotal role. The definitions that have been proposed over the years highlight five underlying characterisations of an information society: technological, economic, sociological, spatial, and cultural. This article discusses those characteristics. While the emergence of an information society may be just a figment of one’s imagination, the concept could be a good organising principle to describe and analyse the changes of the past 50 years and of the future in the 21st century.

This study compared the sensitivity of three shear test methods for measuring the shear bond strength (SBS) of resin cement to zirconia ceramic and evaluated the effects of surface treatment methods on the bonding. Polished zirconia ceramic (Cercon base, DeguDent) discs were randomly divided into four surface treatment groups: no treatment (C), airborne-particle abrasion (A), conditioning with Alloy primer (Kuraray Medical Co.) (P) and conditioning with Alloy primer after airborne-particle abrasion (AP). The bond strengths of the resin cement (Multilink N, Ivoclar Vivadent) to the zirconia specimens of each surface treatment group were determined by three SBS test methods: the conventional SBS test with direct filling of the mold (Ø 4 mm × 3 mm) with resin cement (Method 1), the conventional SBS test with cementation of composite cylinders (Ø 4 mm × 3 mm) using resin cement (Method 2) and the microshear bond strength (μSBS) test with cementation of composite cylinders (Ø 0.8 mm × 1 mm) using resin cement (Method 3). Both the test method and the surface treatment significantly influenced the SBS values. In Method 3, as the SBS values increased, the coefficients of variation decreased and the Weibull parameters increased. The AP groups showed the highest SBS in all of the test methods. Only in Method 3 did the P group show a higher SBS than the A group. The μSBS test was more sensitive to differentiating the effects of surface treatment methods than the conventional SBS tests. Primer conditioning was a stronger contributing factor for the resin bond to zirconia ceramic than was airborne-particle abrasion.

The Indian Vacuum Society (IVS) was established in 1970. It has over 800 members including many from Industry and R & D Institutions spread throughout India. The society has an active chapter at Kolkata. The society was formed with the main aim to promote, encourage and develop the growth of Vacuum Science, Techniques and Applications in India. In order to achieve this aim it has conducted a number of short term courses at graduate and technician levels on vacuum science and technology on topics ranging from low vacuum to ultrahigh vacuum So far it has conducted 39 such courses at different parts of the country and imparted training to more than 1200 persons in the field. Some of these courses were in-plant training courses conducted on the premises of the establishment and designed to take care of the special needs of the establishment. IVS also regularly conducts national and international seminars and symposia on vacuum science and technology with special emphasis on some theme related to applications of vacuum. A large number of delegates from all over India take part in the deliberations of such seminars and symposia and present their work. IVS also arranges technical visits to different industries and research institutes. The society also helped in the UNESCO sponsored post-graduate level courses in vacuum science, technology and applications conducted by Mumbai University. The society has also designed a certificate and diploma course for graduate level students studying vacuum science and technology and has submitted a syllabus to the academic council of the University of Mumbai for their approval, we hope that some colleges affiliated to the university will start this course from the coming academic year. IVS extended its support in standardizing many of the vacuum instruments and played a vital role in helping to set up a Regional Testing Centre along with BARC. As part of the development of vacuum education, the society arranges the participation of

An associative memory using only optical elements has been realized experimentally. The key element of the arrangement is a stimulated-Brillouin-scattering (SBS) selector consisting of a short SBS medium at the focus of a lens. The qualitative advantage of the selector over an SBS mirror is demonstrated experimentally. The response time of the arrangement is ~ 10-8 s and is determined by the duration of the SBS. Estimates show that the SBS selector is capable in practice of distinguishing a signal against background noise when the initial distortion level of the object beam is 10-3. Reliable operation of the SBS selector has been demonstrated for radiative and energy loads reaching 2 GW/cm2 and 2 J, respectively.

Black-Right-Pointing-Pointer RGO disperse homogeneously and form a compact continuous network in matrix (HO-SBS). Black-Right-Pointing-Pointer The percolation threshold of the nanocomposites is of 0.2-0.5 wt% (0.09-0.23 vol%) and its conductivity is up to 1.3 S/m. - Abstract: Flexible and electroconductive nanocomposites based on reduced graphene oxide (RGO) and hydroxylated styrene-butadiene-styrene tri-block copolymer (HO-SBS) were prepared by solution blending method. By the introduction of the groups of -OH and >C=O onto SBS, the compatibility between RGO and SBS was enhanced. Field emission scanning electron microscopy (FE-SEM) and high-resolution transmission electron microscopy (HR-TEM) showed that RGO dispersed homogeneously and formed a compact continuous network in matrix (HO-SBS). The addition of RGO improved the thermal stability of the RGO/HO-SBS nanocomposites while slightly lowered the mechanical property. Moreover, RGO gave the nanocomposites a maximum electrical conductivity up to 1.3 S/m.

Performance Analysis of Machine-Learning Approaches for Modeling the Charging/Discharging Profiles of Stationary Battery Systems with Non-Uniform Cell Aging

Full Text Available The number of Stationary Battery Systems (SBS connected to various power distribution networks across the world has increased drastically. The increase in the integration of renewable energy sources is one of the major contributors to the increase in the number of SBS. SBS are also used in other applications such as peak load management, load-shifting, voltage regulation and power quality improvement. Accurately modeling the charging/discharging characteristics of such SBS at various instances (charging/discharging profile is vital for many applications. Capacity loss due to the aging of the batteries is an important factor to be considered for estimating the charging/discharging profile of SBS more accurately. Empirical modeling is a common approach used in the literature for estimating capacity loss, which is further used for estimating the charging/discharging profiles of SBS. However, in the case of SBS used for renewable integration and other grid related applications, machine-learning (ML based models provide extreme flexibility and require minimal resources for implementation. The models can even leverage existing smart meter data to estimate the charging/discharging profile of SBS. In this paper, an analysis on the performance of different ML approaches that can be applied for lithium iron phosphate battery systems and vanadium redox flow battery systems used as SBS is presented for the scenarios where the aging of individual cells is non-uniform.

Options for the prevention of short-bowel syndrome-associated liver disease (SBS-ALDs) are limited and often ineffective. The farnesoid X receptor (FXR) is a newly emerging pharmaceutical target and FXR agonists have been shown to ameliorate cholestasis and metabolic disorders. The aim of this study was to assess the efficacy of obeticholic acid (OCA) treatment in preventing SBS-ALDs. Piglets underwent 75% small-bowel resection (SBS) or sham surgery (sham) and were assigned to either a daily dose of OCA (2.4 mg/kg/day) or were untreated. Clinical measures included weight gain and stool studies. Histologic features were assessed. Ultraperformance liquid chromatography tandem mass spectrometry was used to determine bile acid composition in end point bile and portal serum samples. Gene expression of key FXR targets was assessed in intestinal and hepatic tissues via quantitative polymerase chain reaction. OCA-treated SBS piglets showed decreased stool fat and altered liver histology when compared with nontreated SBS piglets. OCA prevented SBS-associated taurine depletion, however, further analysis of bile and portal serum samples indicated that OCA did not prevent SBS-associated alterations in bile acid composition. The expression of FXR target genes involved in bile acid transport and synthesis increased within the liver of SBS piglets after OCA administration whereas, paradoxically, intestinal expression of FXR target genes were decreased by OCA administration. Administration of OCA in SBS reduced fat malabsorption and altered bile acid composition, but did not prevent the development of SBS-ALDs. We postulate that extensive small resection impacts the ability of the remnant intestine to respond to FXR activation.

Full Text Available Even though office buildings are usually equipped with ventilation system or air conditioning to create a comfortable working environment, yet there is still found a number of sick building syndrome (SBS symptoms. One of the symptoms of SBS is SBS headache. Therefore, it is crucial to identify risk factors related to SBS headache. Cases were subjects who have suffered SBS headache, and controls were subjects who did not suffered headache for the last one month. Cases and controls were selected through a survey on all of employees in the said office during the period of May to August 2002. Total respondents were 240 employees including 36 people suffered SBS headache (15%. Compared to the normal air movement, faster air movement decreased the risk of SBS headache by 57% [adjusted odds ratio (OR = 0.43; 95% confidence intervals (CI: 0.19-0.95]. Female employees, compared to the males ones, had a higher risk of getting SBS headache by almost three times (adjusted OR = 2.96: 95% CI: 1.29-6.75. Employees who had breakfast irregularly, had a lower risk to SBS headache than those who have breakfast regularly (adjusted OR=0.31; 95% CI: 0.09-0.84. Temperature, humidity and smoking habits were not noted correlated to SBS headache. Female workers had greater risk of suffering SBS headache. In addition slower air movement increased the risk of SBS headache. Therefore, it is recommended to improve the progress of air in order to reduce the risk of SBS headache, especially for female workplace.

The aim was to evaluate the effect of fluoride varnish on the shear bond strength (SBS) on polished and non-polished intact and demineralized enamel. Bovine incisors (half demineralized) were used. Bifluorid 12™ was applied. Bonding was made with Futurabond ® M + and GrandioSO, 24 h and 7 days after varnishing. In some groups, varnish was removed by polishing before bonding. SBS was measured. Fracture type was determined by stereomicroscopy and scanning electron microscope (SEM) observations of the enamel surface were made. Between-group differences were determined by one-way ANOVA and the Tukey test. Associations between study factors and fracture modes were analysed using contingency tables and Pearson's chi-squared test. For intact enamel, SBS on varnished enamel at 24 h was significantly less than in the other groups. SBS recovered 7 days after varnishing. Varnish elimination after 24 h significantly increased the SBS. However, removal at 7 days did not modify SBS. SBS on demineralized enamel groups was significantly less than in intact enamel, except for demineralized enamel varnished and removed at 7 days. Demineralized enamel was associated with cohesive enamel fractures and intact enamel with cohesive fractures of the composite and adhesive fractures. SEM of varnish surfaces showed a homogenous layer scattered with amorphous precipitate. In conclusion, on intact enamel fluoride varnish had a negative effect on SBS at 24 h, which disappeared after 7 days. On demineralized enamel, varnish did not reduce SBS at either time. Polishing the varnished enamel surface showed a similar SBS to intact enamel after 7 days.

The present study systematically reviewed the literature to investigate the effect of phototherapy on the shear bond strength (SBS) of resin cement to zirconia ceramic. electronic databases including MEDLINE (PubMed), ISI Web of Science, Scopus, ScIELO, LILACS and EMBASE until April 2018. The addressed focused question was: Does phototherapy increase the SBS of resin cement to zirconia ceramics?" A total of 8 in-vitro studies were included in the qualitative and quantitative analysis. The mean SBS for phototherapy ranged from 4.1 to 18.95 MPa while mean SBS for sandblasted zirconia-composite specimens ranged from 3.98 to 23.35 MPa in the included studies. Qualitative analysis showed 3 studies favoured application of phototherapy in significantly increasing SBS, while 4 studies indicated sandblasting showed significantly greater SBS of resin cement to zirconia ceramics. Considering the effects of phototherapy, significant heterogeneity for SBS (Q value = 136.37, p<0.0001, I 2  = 94.87%) was noticed among both the groups. The overall mean difference for SBS (SMD = -0.59, 95% CI = -1.99 to -0.80, p = 0.402) was not significant between phototherapy and sandblast (control) groups. Whether the effect of phototherapy on increasing the SBS of resin cement to zirconia ceramic is debatable. Further in-vitro studies should be performed in order to obtain strong conclusions.

Full Text Available Industrial Society is based on mass production and mass distribution of standardized goods and services. The objective of companies is to reduce the unit cost by producing and distributing the same goods in large quantities cheaper than their competitors. Mass production and mass distribution requires an economic model based on centralization; mechanistical, rigid/hierarchical organizational structures; and traditional education. Companies act on the basis of the logic of “produce, store, and sell”. Information Society on the other hand is an indication of a more complex and richer social structure. The objective of companies is to produce mass customized and personalized goods and services for their customers. The customer can buy a personalized good or service with the best price from anywhere in the world. Called “The Age of Terrific Deal” by Robert B. Reich, Information Society requires an economic model based on personalization; dynamic and flat organizational structures; and customer focused education. Companies must act on the basis of the logic of “sell, produce, and deliver”. This paper discusses the major changes that take place during the transition from Industrial Society to Information Society along with basic dynamics of the Information Society.

Environmental stressors, such as high fly density, can affect calf well-being. Sodium bisulfate (SBS) is an acidifier that reduces the pH of flooring and bedding, creating a medium that neither bacteria nor immature flies (also known as larvae or maggots) can thrive in. Two experiments were conducted to investigate the application of SBS to a mixture of rice hull calf bedding and calf slurry (BED) to reduce house fly (Musca domestica L.) larval density and the abundance of bacteria. In experiment 1, dish pans containing 1L of BED and 3,000 house fly eggs were treated with SBS at concentrations of 0, 8.9, 17.7, and 26.5g of SBS/0.05m(2) of BED (CON, LOW, MED, and HIGH, respectively), with each SBS concentration applied to 4 individual pans (16 pans total). Reapplication of the same SBS concentrations in each pan occurred 3 times/wk throughout the 23-d trial. Larval house fly survival was significantly reduced in all pans with SBS relative to CON pans, with lowest survival rates in the MED and HIGH pans (99% and 100% reduction, respectively). The mean pH for each treatment was inversely related to the SBS concentration. In experiment 2, pans containing 1L of BED and 3,000 house fly eggs were treated with either 0g of SBS (CON), 8.9g of SBS/0.05m(2) of BED with reapplication of the acidifier 3 times/wk (SB3x), or 8.9g of SBS/0.05m(2) of BED applied only once at 48h before the end of the 8 d-trial (SB48). Larval house fly survival and bacterial concentrations were reduced (90% larval reduction and 68% bacterial reduction) in the SB3x treatment relative to the CON. Mean pH was also reduced in SB3x pans relative to CON or SB48 pans. Overall, acidification of calf BED using the acidifier SBS resulted in a reduction of bacteria and house fly larval survival. This form of fly control might be expected to reduce adult fly production and, therefore, fly-related stress in calves.

Isotactic polypropylene (PP) was blended in extruder with 0-50% addition of styrene-ethylene/butylene-styrene (SEBS) and styrene-butadiene-styrene (SBS) block copolymers. Granulated blends were irradiated with electron beam (60 kGy) and 1 week later processed with injection molding machine. Properties of samples molded from irradiated and non-irradiated granulates were investigated using DSC, WAXS, MFR, SEM and mechanical and solubility tests. It was found that the SEBS based systems are more resistant to irradiation in comparison to similar blends with SBS copolymer. Such behavior can be explained by the presence of double bonds in elastic SBS block. Irradiation of PP-SBS blends leads to considerable structure changes of crystalline and amorphous PP phases and elastic SBS phase. It indicates creation of new (inter)phase consisting of products of grafting and cross-linking reactions. Irradiated PP-SBS blends show significant improvement of impact strength at low temperatures

Full Text Available Abstract Background Single Base Substitutions (SBS that alter transcripts expressed in cancer originate from somatic mutations. However, recent studies report SBS in transcripts that are not supported by the genomic DNA of tumor cells. Methods We used sequence based whole genome expression profiling, namely Long-SAGE (L-SAGE and Tag-seq (a combination of L-SAGE and deep sequencing, and computational methods to identify transcripts with greater SBS frequencies in cancer. Millions of tags produced by 40 healthy and 47 cancer L-SAGE experiments were compared to 1,959 Reference Tags (RT, i.e. tags matching the human genome exactly once. Similarly, tens of millions of tags produced by 7 healthy and 8 cancer Tag-seq experiments were compared to 8,572 RT. For each transcript, SBS frequencies in healthy and cancer cells were statistically tested for equality. Results In the L-SAGE and Tag-seq experiments, 372 and 4,289 transcripts respectively, showed greater SBS frequencies in cancer. Increased SBS frequencies could not be attributed to known Single Nucleotide Polymorphisms (SNP, catalogued somatic mutations or RNA-editing enzymes. Hypothesizing that Single Tags (ST, i.e. tags sequenced only once, were indicators of SBS, we observed that ST proportions were heterogeneously distributed across Embryonic Stem Cells (ESC, healthy differentiated and cancer cells. ESC had the lowest ST proportions, whereas cancer cells had the greatest. Finally, in a series of experiments carried out on a single patient at 1 healthy and 3 consecutive tumor stages, we could show that SBS frequencies increased during cancer progression. Conclusion If the mechanisms generating the base substitutions could be known, increased SBS frequency in transcripts would be a new useful biomarker of cancer. With the reduction of sequencing cost, sequence based whole genome expression profiling could be used to characterize increased SBS frequency in patient’s tumor and aid diagnostic.

A total of 180 extracted human premolar teeth and 180 premolar stainless steel brackets were used. One hundred teeth and 100 brackets were divided into five groups of 20-teeth each. Four methods of recycling orthodontic brackets were used in each of the first four groups while the last one (group V) was used as the control. Groups (I-V) were subjected to shear force within half an hour until the brackets debond. SBS was measured and the method showing the highest SBS was selected. A New group (VI) was recycled twice with the selected method. Six subgroups (1-6) were established; the primer was applied for three sub-groups, and the composite was applied for all brackets. Brackets were subjected to the same shear force, and SBS was measured for all sub-groups. There was a significant difference between the mean SBS of the sandblasting method and the means of SBS of each of the other three methods. There was however, no significant difference between the mean SBS of the new bracket and the mean SBS of recycled bracket using sandblasting. The mean SBS of all sub-groups were more than that recommended by Reynolds (17) in 1975. Brackets with primer showed slightly higher SBS compared to those of brackets without bonding agent. To decrease cost, sandblasted recycled orthodontic brackets can be used as an alternative to new brackets. It is recommended to apply a bonding agent on the bracket base to provide greater bond strength. Key words:Recycled bracket, shear bond strength, sandblasting, stainless steel orthodontic bracket.

2016-01-01

Full Text Available Sick Building syndrome (SBS and stress have a prevalent influence on organizational productivity and competitiveness. Unhealthy employees not only tend to have high medical leaves but also low productivity due to ailments and discomforts. Studies that investigate the effects of indoor work environment on Sick Building Syndrome (SBS have yielded mixed results while their effect on stress has not been empirically established. Furthermore, studies that simultaneously investigate both SBS and stress are almost non-existent. Thus, this study aimed to study the effects of perceived indoor work environment on SBS and stress and the link between SBS and stress. A cross-sectional survey participated by 598 employees from various industries was conducted from September to October 2015. Data were analyzed using Partial Least Square Structural Equation Modeling (PLS-SEM to assess both the measurement model and the path structure. The results suggest that indoor work environment has significant yet the weak effect on SBS while it has no effect on stress. However, SBS has a strong significant relationship with stress. The implication of this study on the importance of conducive indoor work environment is discussed with suggestions for future studies.

Co-production of fermentable sugars and nanofibrillated cellulose from cassava pulp was achieved by the combination of thermophilic enzymes (endoglucanase, β-glucosidase, and α-amylase) and a new atomization system (Star Burst System; SBS), which employs opposing water jets. The SBS represents a key technology for providing cellulose nanofibers and improving the enzymatic saccharification of cassava pulp. Depending on the enzymes used, the production of glucose from cassava pulp treated with the SBS was 1.2- to 2.5-fold higher than that from pulp not treated with the SBS. Nanofibrillated cellulose with the gel-like property in suspension was produced (yield was over 90%) by α-amylase treatment, which completely released trapped starch granules from the fibrous cell wall structure of cassava pulp pretreated with the SBS. The SBS provides an environmentally low-impact pretreatment system for processing biomass material into value-added products. Copyright © 2012 Elsevier Ltd. All rights reserved.

Nielsen, Jonas Willum; Kramhøft, Birte; Bozonnet, Sophie

2012-01-01

Barley α-amylase isozyme 1 (AMY1, EC 3.2.1.1) contains two surface binding sites, SBS1 and SBS2, involved in the degradation of starch granules. The distinct role of SBS1 and SBS2 remains to be fully understood. Mutational analysis of Tyr-380 situated at SBS2 previously revealed that Tyr-380...... is required for binding of the amylose helix mimic, β-cyclodextrin. Also, mutant enzymes altered at position 380 displayed reduced binding to starch granules. Similarly, binding of wild type AMY1 to starch granules was suppressed in the presence of β-cyclodextrin. We investigated the role of SBS2 by comparing...... kinetic properties of the wild type AMY1 and the Y380A mutant enzyme in hydrolysis of amylopectin, amylose and β-limit dextrin, and the inhibition by β-cyclodextrin. Progress curves of the release of reducing ends revealed a bi-exponential hydrolysis of amylopectin and β-limit dextrin, whereas hydrolysis...

Kokol, Peter; Blažun Vošner, Helena; Vermeulen, Joeri

Sleeping Beauties (SBs) are publications that are scarcely cited in the years immediately following publication but then suddenly become highly cited later. Such publications have unique citation patterns and can reveal important developments in the field in which they appear. No holistic analysis of nursing SBs has been done yet. The aim of this study was to identify and analyze the SB phenomenon in the nursing research literature. The corpus for the nursing SB identification was harvested from the Web of Science Core Collection (Thomas Reuters) for the period 1934-2015. Citation histories of 212,239 publications were screened. From those, 3,209 publications with more than 100 citations were selected for analysis. We used our own software and applied the van Raan (2004) and Baumgartner (2010) criteria for SBs-a 5-year sleeping period with at most 10 citations during that time, an average of at least five citations per year after the first 10 years, with at least 100 citations in total. The knowledge context for SBs was determined using citing papers. All citing papers were analyzed with the help of VOSviewer software. Nine publications were identified as SBs (prevalence of 0.004%). The length of sleep duration ranged from 5 to 10 years (M = 6.8, SD = 2.0), depth of sleep ranged from 0.2 to 0.8 citations (M = 0.6, SD = 0.2), and awake intensity ranged from 6.4 to 15.0 citations (M = 11.0, SD = 3.8). The average number of citations to SBs was 229. Most nursing SBs were produced in the United States (n = 8) from top institutions in journals with high-impact factors. Nursing SBs covered topics including resilience, sampling in qualitative research, metasynthesis, postoperative pain in children, dementia rating scales, care of patients with Alzheimer's disease, nursing theory related to fatigue mechanisms in cancer patients, and family participation during resuscitation. Nursing SBs were cited by authors from a large number of institutions and countries; the number of

Full Text Available Background. Failure of orthodontic bracket bonds is a common occurrence during orthodontic treatment. Different techniques have been suggested in the literature to remove resin residues from the bracket bases and enamel surfaces to prepare the surfaces again after debonding. This study attempted to compare multiple rebond shear strengths (SBS of debonded brackets following preparation with sandblasting and CO2 laser. Methods. The brackets were bonded on 30 human and bovine maxillary central incisors using self-curing composite resin. SBS was measured using Hounsfield testing machine. The brackets were rebonded for two other times after composite resin residues on their surfaces were removed, either with air abrasion or CO2 laser. The debonded brackets and enamel surfaces were also evaluated after each debonding procedure under a stereomicroscope in order to determine adhesive remnant index (ARI. SBS of debonded brackets after each step were compared between sandblast and CO2 laser groups. Results. We observed significant differences in SBS values between pre-recycling and first (P = 0.04, second (P = 0.007 and third recycling (P = 0.007 with laser. Recycling with sandblasting resulted in a decrease in SBS after the first and second recycling procedure; however, the SBS increased after the third recycling procedure, with no significant differences. Conclusion. SBS of brackets after recycling with sandblasting and laser beams was not significantly different, and both were at a favorable level. However, repeating the recycling procedure with sandblasting resulted in more favorable SBS compared to laser.

Shaken baby syndrome (SBS) results in cerebral trauma. Creating awareness through education may improve parental response to a distressed infant. We aim to assess current parental understanding of SBS and identify knowledge gaps. A prospective assessment was carried out in two independent maternity hospitals (National Maternity Hospital (NMH) and Midland Regional Hospital (MRH)) over a 4-month period. Multi-dimensional questionnaires were distributed to parents (n = 233) and results were assessed anonymously. Statistical analysis was performed using SPSS21 software. Two hundred thirty-three participants were included: n = 114 (NMH), n = 119 (MRH). Fifty-four percent (n = 62, NMH) and 50 % (n = 60, MRH) had never heard of SBS. Of those who had, media was the commonest source: 94 % (47/50) NMH; 86 % (47/59) MRH. Less than 1 % of participants obtained information through a health care provider. Nearly all respondents wanted further information, regardless of whether they had prior knowledge (100 % (NMH); 99.2 % (MRH)). Participants wanted information delivered via a midwife (51 % (58/114) NMH; 45 % (54/119) MRH), with reading material (61 % (69/114) NMH; 59 % (70/119) MRH), during pre-natal period (50 % (57/114) NMH; 65 % (77/119) MRH). Importantly, parents of Irish origin were more likely to have heard of SBS compared to those of non-Irish origin (p = 0.026 (NMH), p = 0.020 (MRH)). Half of all participants had no prior knowledge of SBS, with majority expressing interest in learning more. Therefore, a national "Don't Shake" campaign is evolving. • Studies have shown that educating parents regarding shaken baby syndrome (SBS) may result in a more safe and appropriate response to infant crying [ 3 ]. • In Ireland, there is no such education provided to parents in maternity hospitals. What is New: • Just over half of our participants had not heard of SBS, and we have identified parental perceptions of SBS, and parents preferred method of

The effect of natural and lactic acid bacteria (LAB) fermentation processes on metabolite changes in pastes of soybeans and soybean–maize blends was studied. Pastes composed of 100% soybeans, 90% soybeans and 10% maize, and 75% soybeans and 25% maize were naturally fermented (NFP), and were fermented by lactic acid bacteria (LFP). LAB fermentation processes were facilitated through back-slopping using a traditional fermented gruel, thobwa as an inoculum. Naturally fermented pastes were designated 100S, 90S, and 75S, while LFP were designated 100SBS, 90SBS, and 75SBS. All samples, except 75SBS, showed highest increase in soluble protein content at 48 h and this was highest in 100S (49%) followed by 90SBS (15%), while increases in 100SBS, 90S, and 75S were about 12%. Significant (P acids throughout fermentation were attributed to cysteine in 100S and 90S; and methionine in 100S and 90SBS. A 3.2% increase in sum of total amino acids was observed in 75SBS at 72 h, while decreases up to 7.4% in 100SBS at 48 and 72 h, 6.8% in 100S at 48 h and 4.7% in 75S at 72 h were observed. Increases in free amino acids throughout fermentation were observed in glutamate (NFP and 75SBS), GABA and alanine (LFP). Lactic acid was 2.5- to 3.5-fold higher in LFP than in NFP, and other organic acids detected were acetate and succinate. Maltose levels were the highest among the reducing sugars and were two to four times higher in LFP than in NFP at the beginning of the fermentation, but at 72 h, only fructose levels were significantly (P acid solubility and degradation of phytic acid (85% in NFP and 49% in LFP by 72 h).

Full Text Available Introduction: Over the past two decades, numerous studies on indoor air and the Sick Building Syndrome (SBS have been conducted, mostly in office environments. However, there is little knowledge about SBS in police officers. This study was aimed to fill this gap. Methods: A cross-sectional questionnaire survey was conducted in 2016 at the Triveneto Penitentiary Center, Northern Italy. Chi-square was used to test the difference of prevalence between office workers (OWs and correctional officers (COs of personal characteristics, cases of SBS, and general and mucocutaneous symptoms associated with SBS. A binary logistic regression was used to identify among individual, environmental, and psychosocial characteristics, factors associated with correctional officers’ Sick Building Syndrome. Results: Chi-squared analyses revealed that there were statistically significant differences in the estimated prevalence of SBS general symptoms (χ2 (1 = 12.22, P < .05, SBS mucocutaneous symptoms (χ2 (1 = 9.04, P < .05, and cases of SBS (χ2 (1 = 4.39, P <.05 between COs and OWs. COs reported that their health had been affected by the passive smoking (β = 2.34, P < .05 and unpleasant odour (β = 2.51, P < .05 as environmental risk factors; work-family conflict (β = 2.14, P < .05, psychological and physical isolation (β = 2.07, P < .05, and negative public image (β = 2.06, P < .05 as psychosocial risk factors. Finally, atopy (β = 2.02, P < .05 and to be current smoker (β = 2.02, P < .05 were statistically significant behavioral predictors of SBS among correctional officers. Discussion: Our survey showed that symptoms compatible with the sick building syndrome are common in correctional officers and that psychosocial work climate and exposure to passive smoking could have a strong influence on the prevalence of both general and mucocutaneous symptoms associated with SBS.

Lees, Marjorie B

2002-11-01

Women have made important scientific contributions to the field of neurochemistry, and they have also been leaders in neurochemical societies throughout the world. Here I discuss women's involvement and leadership in six neurochemistry societies: American Society for Neurochemistry, Argentine Society for Neurochemistry, International Society for Neurochemistry, European Society for Neurochemistry, Japanese Society for Neurochemistry, and Asian-Pacific Society for Neurochemistry. The number of women who have been active in these societies and the level of their activity vary considerably. Neurochemical societies in the Western hemisphere, i.e., the American and the Argentine Society for Neurochemistry, have much greater numbers of women who have held office, been on council, or engaged in other leadership activities than in the rest of the world. The limited participation of women in the Japanese Neurochemistry Society relates to Japanese cultural views and was not unexpected. However, the relatively few women leaders in the International Society for Neurochemistry was a surprise. The European Society had a somewhat better record of female participation than did the International Society. The reasons for these differences are partly cultural, but factors related to when each society was formed, how it is organized, and how elections are structured undoubtedly play a role. Further analysis of these observations would be of interest from a sociological and a women's studies point of view.

Full Text Available PURPOSE: To evaluate if bovine enamel and dentin are appropriate substitutes for the respective human hard tooth tissues to test shear bond strength (SBS and fracture analysis. MATERIALS AND METHODS: 80 sound and caries-free human erupted third molars and 80 freshly extracted bovine permanent central incisors (10 specimens for each group were used to investigate enamel and dentine adhesion of one 2-step self-etch (SE and one 3-step etch and rinse (E&R product. To test SBS the buccal or labial areas were ground plane to obtain appropriate enamel or dentine areas. SE and E&R were applied and SBS was measured prior to and after 500 thermocycles between +5 and +55°C. Fracture analysis was performed for all debonded areas. RESULTS: ANOVA revealed significant differences of enamel and dentin SBS prior to and after thermocycling for both of the adhesives. SBS- of E&R-bonded human enamel increased after thermocycling but SE-bonded did not. Bovine enamel SE-bonded showed higher SBS after TC but E&R-bonded had lower SBS. No differences were found for human dentin SE- or E&R-bonded prior to or after thermocycling but bovine dentin SE-bonded increased whereas bovine dentine E&R-bonded decreased. Considering the totalized and adhesive failures, fracture analysis did not show significances between the adhesives or the respective tooth tissues prior to or after thermocycling. CONCLUSION: Although SBS was different on human and bovine teeth, no differences were found for fracture analysis. This indicates that solely conducted SBS on bovine substrate are not sufficient to judge the perfomance of adhesives, thus bovine teeth are questionnable as a substrate for shear bond testing.

ABSTRACT Objective: The aim of this in vitro study was to evaluate and compare the effects of grinding, drilling, sandblasting, and ageing prefabricated teeth (PfT) on the shear bond strength (SBS) of orthodontic brackets, as well as the effects of surface treatments on the adhesive remnant index (ARI). Methods: One-hundred-ninety-two PfT were divided into four groups (n = 48): Group 1, no surface treatment was done; Group 2, grinding was performed with a cylindrical diamond bur; Group 3, two drillings were done with a spherical diamond bur; Group 4, sandblasting was performed with 50-µm aluminum oxide. Before the experiment, half of the samples stayed immersed in distilled water at 37oC for 90 days. Brackets were bonded with Transbond XT and shear strength tests were carried out using a universal testing machine. SBS were compared by surface treatment and by ageing with two-way ANOVA, followed by Tukey’s test. ARI scores were compared between surface treatments with Kruskal-Wallis test followed by Dunn’s test. Results: Surface treatments on PfT enhanced SBS of brackets (p< 0.01), result not observed with ageing (p= 0.45). Groups II, III, and IV showed higher SBS and greater ARI than the Group 1 (p< 0.05). SBS was greater in the groups 3 and 4 (drilling, sandblasting) than in the Group 2 (grinding) (p< 0.05). SBS and ARI showed a positive correlation (Spearman’s R2= 0.57; p< 0.05). Conclusion: Surface treatment on PfT enhanced SBS of brackets, however ageing did not show any relevance. Sandblasting and drilling showed greater SBS than grinding. There was a positive correlation between SBS and ARI. PMID:28902249

2006-01-01

A high performance phase conjugate mirror based on stimulated Brillouin scattering (SBS-PCM) has been applied to the Thomson scattering system in the JT-60U tokamak for the first time in order to improve the measurement performance. A SBS-PCM realized a high reflectivity of 95% at a high input power of 145 W (2.9 J, 50 Hz). Using the SBS-PCM, two methods have been developed to increase the intensity of scattered light. For the first method, we have developed a new optical design to provide a double-pass scattering method with the SBS-PCM. A laser beam passing through the plasma is reflected by the SBS-PCM. The reflected beam passes the plasma again along the same path by means of the phase conjugation of the optically nonlinear stimulated Brillouin scattering process. The double-pass Thomson scattering method using the SBS-PCM has demonstrated an increase of the scattered light by a factor of 1.6 compared with the single-pass scattering method in JT-60U. A multipass Thomson scattering method in which the laser beam can be confined between a couple of SBS-PCMs is also proposed. It is estimated that the multipass scattering method generates the scattered light more than several times as large as that of the single-pass scattering method. For the second method, a high-average-power yttrium aluminum garnet (Nd:YAG) laser system has been developed using the SBS-PCM. The SBS-PCM effectively compensated thermal degradation at two amplifier lines, and the average power was increased by a factor of >8 from 45 W (1.5 J, 30 Hz) to 373 W (7.46 J, 50 Hz). A Nd:YAG laser (5 J, 100 Hz) for the edge Thomson scattering in International Thermonuclear Experimental Reactor (ITER) has been designed based on the result

Full Text Available Short bowel syndrome (SBS is a cause of significant morbidity and mortality in children. Probiotics, due to their beneficial effects on the gastrointestinal tract (e.g., improving gut barrier function, motility, facilitation of intestinal adaptation and decreasing pathogen load and inflammation may have a therapeutic role in the management of SBS. To conduct a systematic review of the current evidence for the effects of probiotic supplementation in children with SBS, the standard Cochrane methodology for systematic reviews was used. The databases, Pubmed, Embase, ACTR, CENTRAL, and the international trial registry, and reference lists of articles were searched for randomised (RCT or quasi-randomised controlled trials reporting on the use of probiotics in SBS. Our search revealed no RCTs on the use of probiotics in children with SBS. We found one small cross-over RCT (placebo controlled crossover clinical trial, one case control study and nine case reports on the use of probiotics in children with SBS. In the crossover RCT, there was no consistent effect on intestinal permeability (primary outcome after supplementation with Lactobacillus rhamnosus (LGG in nine children with SBS. The case control study (four cases: four controls reported a trend for increase in height and weight velocity and improvement in non-clinical outcomes, such as gut flora, lymphocyte count and serum prealbumin. Five of the nine case reports showed that children (n = 12 with SBS were benefited (e.g., cessation of diarrhoea, improved faecal flora, weight gain and weaning from parenteral nutrition by probiotic supplementation. The remaining four reported on the adverse effects, such as Lactobacillus sepsis (n = 3 and d-lactic acidosis (n = 2. There is insufficient evidence on the effects of probiotics in children with SBS. The safety and efficacy of probiotic supplementation in this high-risk cohort needs to be evaluated in large definitive trials.

A huge flow of quantitative social, demographic and behavioral data is becoming available that traces the activities and interactions of individuals, social patterns, transportation infrastructures and travel fluxes. This has caused, together with innovative computational techniques and methods for modeling social actions in hybrid (natural and artificial) societies, a qualitative change in the ways we model socio-technical systems. For the first time, society can be studied in a comprehensive fashion that addresses social and behavioral complexity. In other words we are in the position to envision the development of large data and computational cyber infrastructure defining an exploratory of society that provides quantitative anticipatory, explanatory and scenario analysis capabilities ranging from emerging infectious disease to conflict and crime surges. The goal of the exploratory of society is to provide the basic infrastructure embedding the framework of tools and knowledge needed for the design of forecast/anticipatory/crisis management approaches to socio technical systems, supporting future decision making procedures by accelerating the scientific cycle that goes from data generation to predictions.

Religion, civil society and conflict: What is it that religion does for and to society?

Directory of Open Access Journals (Sweden)

Jaco Beyers

2011-08-01

Full Text Available Human consciousness instinctively tries to make sense of reality. Different human interpretations of reality lead to a world consisting of multiple realities. Conflict occurs when differing realities (worldviews encounter one another. Worldviews are socially created and determine human behaviour and, as such, most often find expression in religion. The discussion of conflict and the role of religion in civil society take place within the discourse of the sociology of religion. Religion is socially determined. Peter Berger’s insight into the sociology of religion therefore plays an important role in establishing the relationship between religion and civil society as one that takes on different forms. Thus, a clear definition of both civil society and religion was needed to understand the nature of these relationships. The role of religion in civil society with regard to the presence of conflict in society was further investigated in this article. The conditions under which conflict in society occurs were discussed, as were the conditions for tolerance in society, for religion ultimately becomes the provider of moral discernment when conflict occurs in civil society.

Full Text Available OBJECTIVE: To compare in vitro shear bond strength (SBS of different orthodontic adhesives in bonding and repeatedly rebonding metal brackets, and to evaluate the bond failure site with the adhesive remnant index (ARI. METHODS: Specimens consisted of 90 extracted human first premolars, randomly divided into three groups (n=30. The adhesives Alpha Plast (AP, ConciseTM (CO and TransbondTM XT (TB were used in each group. Three SBS tests were performed, i.e., one at T0 (initial and the other two at T1 and T2 (first and second rebondings, respectively, observing a 24-hour interval. The tests were performed in a Shimadzu AG-I (10kN SBS testing machine, at a speed of 0.5 mm/min. RESULTS: SBS data were subjected to ANOVA, Tukey's test and Bonferroni test (p<0.05. For the ARI, the Kruskal Wallis test was performed, followed by the Dunn test. The results revealed that at T0 groups AP and CO showed SBS values that were near, but above TB values; and at T1 and T2, the highest SBS values were observed for the AP group, followed by the CO and TB groups. CONCLUSION: Statistically significant differences were found in SBS between groups AP, CO and TB during bonding and repeated rebondings of unused metal brackets, with group AP achieving the highest SBS value. Regarding ARI, adhesive AP exhibited bond failure at the enamel-adhesive interface, with a higher enamel fracture frequency.

2012-01-01

Tri-steps modified styrene-butadiene-styrene block copolymer (SBS) membrane was prepared with epoxidation, ring opening reaction with maleated ionomer and layer-by-layer assembled polyelectrolyte technique. The tri-steps modified SBS membrane was characterized by infrared spectroscopy and X-ray photoelectron spectroscope (XPS). The structures of the modified SBS membranes were identified with methylene blue and azocarmine G. The content of amino group on the surface of the modified membrane was calculated from uptake of an acid dye. The values of the contact angle, water absorption, water vapor transmission rate and the adsorption of fibronectin on the membranes were determined. To evaluate the biocompatibility of the tri-steps modified SBS membrane, the cytotoxicity, antibacterial and growth profile of the cell culture of 3T3 fibroblasts on the membrane were evaluated. The bactericidal activity was found on the modified SBS. From the cell culture of 3T3 fibroblasts on the membrane, it revealed that the cells not only remained viable but also proliferated on the surface of the tri-steps modified SBS membranes. As the membranes are sterile semipermeable with bactericidal activity and transparent allowing wound checks, they can be considered for shallow wound with low exudates. - Highlights: ► Styrene-butadiene-styrene block copolymer (SBS) was modified with tri-steps. ► The tri-steps are epoxidation, ring opening reaction and layer-by-layer assembly. ► Modified SBS membrane for wound dressing is evaluated. ► Membranes are sterile semipermeable with bactericidal activity and transparent. ► Membranes can be considered for shallow wound with low exudates.

Bitumen nanocomposites with improved performance

KAUST Repository

Kosma, Vasiliki

2017-11-29

Bitumen-clay nanocomposite binders with styrene-butadienestyrene triblock copolymer, SBS, and combinations of SBS and crumb rubber (CR) with different CR/SBS ratios have been synthesized and characterized. In addition to the binder, samples containing the binder and concrete sand (with a weight ratio 1:9) were prepared. The modified binders were studied in terms of filler dispersion, storage stability, mechanical performance and water susceptibility. We demonstrate that the samples containing nanoclays consistently outperform those based only on the polymer additives. We also find that nanocomposite samples based on a combination of SBS and CR are best, since in addition to other improvements they show excellent storage stability. Our work shows that substituting CR with SBS as a bitumen additive and combining it with inexpensive nanoclays leads to new materials with enhanced performance and improved stability for practical asphalt applications.

2011-01-01

Based on the wave coupling theory and the evolution model of the critical pump power (or Brillouin threshold) for stimulated Brillouin scattering (SBS) in double-clad fiber amplifiers, the influence of signal bandwidth, fiber-core diameter and amplifier gain on SBS threshold is simulated theoretically. And experimental measurements of SBS are presented in ytterbium-doped double-clad fiber amplifiers with single-frequency hundred nanosecond pulse amplification. Under different input signal pulses, the forward amplified pulse distortion is observed when the pulse energy is up to 660 nJ and the peak power is up to 3.3 W in the pulse amplification with pulse duration of 200 ns and repetition rate of 1 Hz. And the backward SBS narrow pulse appears. The pulse peak power equals to SBS threshold. Good agreement is shown between the modeled and experimental data. (authors)

To improve the dielectric performance of high-dielectric-constant conductive filler/polymer composites, polyaniline was deposited on exfoliated graphite nanoplates (xGNPs) by in-situ polymerization method to form polyaniline (PANI) coated xGNPs (xGNPs@PANI) as the conductive filler for the oxidized styrene-butadienestyrene copolymer (SBS-FH) containing both hydroxyl and formyloxy groups. The results of TEM, SEM, FTIR, TGA, Raman spectrum, XPS, and WAXD showed that PANI had been coated onto the surface of xGNPs successfully. The xGNPs@PANI/SBS-FH composites were prepared by a simple solution-blending method and the homogenous distribution of xGNPs@PANI in the SBS-FH matrix was confirmed by SEM. The presence of xGNPs@PANI was found to significantly improve the dielectric properties of resultant composite compared to the unmodified xGNPs. For example, the xGNPs@PANI/SBS-FH composite near percolation threshold filled with 9.38 vol.% xGNPs@PANI showed a dielectric constant of 56.8 and a dielectric loss factor of 0.51 at 1000 Hz, while the corresponding values of xGNPs (1.19 vol.%)/SBS composite were 15.96 and 2.91 at 1000 Hz, respectively. In addition, the incorporation of xGNPs@PANI into SBS-FH could effectively enhance the thermal conductivity of resultant xGNPs@PANI/SBS-FH composite.

Early observations of enamel surfaces prepared by erbium lasers motivated clinicians to use laser as an alternative to chemical etching. Evaluate shear bond strength (SBS) values of different dental adhesives on Erbium:Yttrium Aluminum Garnet (Er:YAG) laser prepared enamel and to evaluate possible etching patterns correlations between dental adhesives and SBS values. One hundred bovine incisors were randomly assigned to SBS tests on enamel (n = 15) and to enamel morphology analysis (n = 5) after Er:YAG laser preparation as follows: Group I - 37% phosphoric acid (PA)+ ExciTE(®); Group II - ExciTE(®); Group III - AdheSE(®) self-etching; Group IV - FuturaBond(®) no-rinse. NR; Group V - Xeno(®) V. Teeth were treated with the adhesive systems and subjected to thermal cycling. SBS were performed in a universal testing machine at 5 mm/min. One-way ANOVA and post-hoc tests (P adhesive systems yielded significantly different SBSs. Acid etching significantly increased the adhesion in laser treated enamel. No differences in SBS values were obtained between AdheSE(®) and ExciTE(®) without condition with PA. FuturaBond(®) NR and Xeno(®) V showed similar SBS, which was lower in comparison to the others adhesives. No correlation between enamel surface morphology and SBS values was observed, except when PA was used.

Modification of polymer blends by irradiation

1999-01-01

Modification of polymers, especially of polyolefin-elastomer blends (e. g. ethylene/propylene/diene terpolymer, ethylene propylene copolymer, ethylene/vinyl acetate copolymer etc.), by irradiation with a beam of fast electrons is discussed. Irradiation of polymer blends usually results in enhanced interactions between the constituents, caused among other things, by grafting induced at the polymer interphase. As a result, mechanical properties are affected to an extent depending on the proportion and type of constituent polymers, stabilizer content and radiation dose. Breaking strength (σ) relative elongation at break (ε) and melt flow rate (MFR), were examined for a triblock styrene/butadiene/styrene (SBS) copolymer, polypropylene (PP), and a PP-SBS blend (50:50 by wt.). In PP, the content of the crystal phase was determined. Irradiation was found to make SBS crosslink, as a result, σ rose by 25% and ε remained unaffected. PP was found to become degraded upon irradiation (MFR rose as much as 16 times), thereby σ and ε decreased considerably. In pure PP, the content of the crystal phase was found to increase. The variations of σ and ε in the irradiated PP-SBS blend follow a tendency similar to that in the SBS copolymer examined. This fact suggests the SBS copolymer to have a decisive effect on the macroscopic properties of the PP-SBS blend. (author)

Benefits of recombinant human growth hormone (rhGH) alone or combined with glutamine in patients with intestinal failure because of short-bowel syndrome remain controversial. We explored effects of rhGH on whole-body protein metabolism in patients with short-bowel syndrome with intestinal failure (SBS-IF) to gain insight into its mechanism of action. Eight stable hyperphagic patients with severe SBS-IF received, in a double-blind, randomized crossover study, low-dose rhGH (0.05 mg · kg⁻¹ · d⁻¹) and a placebo for two 3-wk periods. Leucine and glutamine kinetics under fasting and fed conditions, fat-free mass (FFM), and serum insulin were determined on the final day of each treatment. rhGH increased FFM and nonoxidative leucine disposal (NOLD; an index of protein synthesis) (P de novo synthesis (P de novo synthesis and intestinal absorption increase glutamine availability over the physiologic range, suggesting that beneficial effects of rhGH in hyperphagic patients might be achieved without glutamine supplementation. © 2014 American Society for Nutrition.

Full Text Available Background and aims Building associated illnesses are a group of illnesses caused by physical or psychological conditions of workplace. One of theses illnesses is sick building syndrome (SBS which consists of a group of symptoms, including mucosal irritation, headache, fatigue, skin dryness and itching, and nausea that are temporally related to presence in a particular building. This study was designed to assess SBS and factors affecting it in central building of Shahid Sadoughi University of medical sciences.   Methods This is a cross-sectional study on workers of central building of Shahid Sadoughi University of medical sciences. The prevalence of SBS was determined using self-administered indoor air quality (IAQ questionnaire for office workers. All workers who worked at least one year in this building and had no other medical illnesses with similar symptoms to SBS, entered the study and the questionnaire was filled out for them. Data was analyzed using chi square test.   ResultsPrevalence of SBS among the workers of central building was 35.7% (34.8% in male and 36.9% in female workers. There was no significant association between prevalence of SBS and age, gender, duration of employment and level of education. The most frequent complaints mentioned by participants were fatigue and headache, and the most frequent causes were noise, inadequate physical space and crowded work environment.   Conclusion This survey showed a relatively high prevalence of SBS among office workers in this organization. So considering the effects of SBS on workers' function and productivity, it is recommended to reduce its causes, especially noise and inadequate space.

Tri-steps modified styrene-butadiene-styrene block copolymer (SBS) membrane was prepared with epoxidation, ring opening reaction with maleated ionomer and layer-by-layer assembled polyelectrolyte technique. The tri-steps modified SBS membrane was characterized by infrared spectroscopy and X-ray photoelectron spectroscope (XPS). The structures of the modified SBS membranes were identified with methylene blue and azocarmine G. The content of amino group on the surface of the modified membrane was calculated from uptake of an acid dye. The values of the contact angle, water absorption, water vapor transmission rate and the adsorption of fibronectin on the membranes were determined. To evaluate the biocompatibility of the tri-steps modified SBS membrane, the cytotoxicity, antibacterial and growth profile of the cell culture of 3T3 fibroblasts on the membrane were evaluated. The bactericidal activity was found on the modified SBS. From the cell culture of 3T3 fibroblasts on the membrane, it revealed that the cells not only remained viable but also proliferated on the surface of the tri-steps modified SBS membranes. As the membranes are sterile semipermeable with bactericidal activity and transparent allowing wound checks, they can be considered for shallow wound with low exudates. - Highlights: Black-Right-Pointing-Pointer Styrene-butadiene-styrene block copolymer (SBS) was modified with tri-steps.

Available evidence suggests that patients with short bowel syndrome (SBS) might be at risk of vitamins A, D, E and B(1) deficiency. However, there is little clinical data describing the vitamin K status. Therefore, in the present study we aimed to assess the body resources of vitamin K in a subset of SBS patients. The study comprised 33 patients aged 1 month to 16 years. PIVKA-II concentrations were determined in all subjects. In all studied subjects, coagulation parameters were normal. PIVKA-II levels indicative of vitamin K deficiency was found in 3 (9.1%) SBS patients. One patient had been receiving an additional intravenous vitamin K dose of 5 mg/week. In all SBS patients with cirrhosis and cholestasis, PIVKA-II concentrations were low (vitamin K several times a month. Vitamin K deficiency may appear in SBS patients. Copyright © 2012.

There of it was implemented an inquiry aimed to this type of businesses as borrowers of funds. The chi-square test led us to the conclusion that the lack of information has propitiated that the financing for the MiSBs had been mainly from informal sources. The loans mixtures obtained have not been sufficient to realise the MiSBs investment projects, this credit rationing from the bank system, has been one of the main obstacles that MiSBs have had to modernize themselves and to become more competitive. This paper is the first part of a major research upon the credit market of MiSBs in Tabasco, Mexico, which also involves the analysis of the sources of loans in this market.

Shaken-baby syndrome (SBS) is a type of child abuse caused by violent shaking of an infant, with or without impact, and characterized by subdural hematomas, retinal hemorrhages, and occult bone fractures. Parenchymal brain lesions in SBS may be missed or underestimated on CT scans, but can be detected at an earlier stage with diffusion-weighted MRI (DW-MRI) as areas of restricted diffusion. We demonstrate the value of DW-MRI in a 2-month-old baby boy with suspected SBS. The pattern of diffusion abnormalities indicates that the neuropathology of parenchymal lesions in SBS is due to hypoxic-ischemic brain injuries, and not to diffuse axonal injury. (orig.)

Stability-based sorting: The forgotten process behind (not only) biological evolution.

Science.gov (United States)

Toman, Jan; Flegr, Jaroslav

2017-12-21

Natural selection is considered to be the main process that drives biological evolution. It requires selected entities to originate dependent upon one another by the means of reproduction or copying, and for the progeny to inherit the qualities of their ancestors. However, natural selection is a manifestation of a more general persistence principle, whose temporal consequences we propose to name "stability-based sorting" (SBS). Sorting based on static stability, i.e., SBS in its strict sense and usual conception, favours characters that increase the persistence of their holders and act on all material and immaterial entities. Sorted entities could originate independently from each other, are not required to propagate and need not exhibit heredity. Natural selection is a specific form of SBS-sorting based on dynamic stability. It requires some form of heredity and is based on competition for the largest difference between the speed of generating its own copies and their expiration. SBS in its strict sense and selection thus have markedly different evolutionary consequences that are stressed in this paper. In contrast to selection, which is opportunistic, SBS is able to accumulate even momentarily detrimental characters that are advantageous for the long-term persistence of sorted entities. However, it lacks the amplification effect based on the preferential propagation of holders of advantageous characters. Thus, it works slower than selection and normally is unable to create complex adaptations. From a long-term perspective, SBS is a decisive force in evolution-especially macroevolution. SBS offers a new explanation for numerous evolutionary phenomena, including broad distribution and persistence of sexuality, altruistic behaviour, horizontal gene transfer, patterns of evolutionary stasis, planetary homeostasis, increasing ecosystem resistance to disturbances, and the universal decline of disparity in the evolution of metazoan lineages. SBS acts on all levels in

Introduction Parenteral nutrition (PN) dependence in short bowel syndrome (SBS) patients is linked to the functionality of the remnant small bowel (RSB). Patients may wean off PN following a period of intestinal adaptation that restores this functionality. Currently, plasma citrulline is the standard biomarker for monitoring intestinal functionality and adaptation. However, available studies reveal that the relationship the biomarker with the length and function of the RSB is arguable. Thus, having additional biomarkers would improve pointing out PN weaning. Aim By measuring concomitant changes in citrulline and the novel biomarker apolipoprotein AIV (Apo AIV), as well as taking into account the anatomy of the RSB, this exploratory study aims to a better understanding of the intestinal adaptation process and characterization of the SBS patients under PN. Methods Thirty four adult SBS patients were selected and assigned to adapted (aSBS) and non-adapted (nSBS) groups after reconstructive surgeries. Remaining jejunum and ileum lengths were recorded. The aSBS patients were either on an oral diet (ORAL group), those with intestinal insufficiency, or on oral and home parenteral nutrition (HPN group), those with chronic intestinal failure. Apo AIV and citrulline were analyzed in plasma samples after overnight fasting. An exploratory ROC analysis using citrulline as gold standard was performed. Results Biomarkers, Apo AIV and citrulline showed a significant correlation with RSBL in aSBS patients. In jejuno-ileocolic patients, only Apo AIV correlated with RSBL (rb = 0.54) and with ileum length (rb = 0.84). In patients without ileum neither biomarker showed any correlation with RSBL. ROC analysis indicated the Apo AIV cut-off value to be 4.6 mg /100 mL for differentiating between the aSBS HPN and ORAL groups. Conclusions Therefore, in addition to citrulline, Apo AIV can be set as a biomarker to monitor intestinal adaptation in SBS patients. As short bowel anatomy is shown

The aim of this study was to determine the relationship between enamel surface microhardness and microshear bond strength (microSBS). Buccal and lingual mid-coronal enamel sections were prepared from 22 permanent human molars and divided into two groups, each comprising the buccal and lingual enamel from 11 teeth, to analyze two self-etching primer adhesives (Clearfil SE Bond and Tokuyama Bond Force). One-half of each enamel surface was tested using the Vickers hardness test with 10 indentations at 1 N and a 15-s dwell time. A hybrid resin composite was bonded to the other half of the enamel surface with the adhesive system assigned to the group. After 24 h of water storage of specimens at 37 degrees C, the microSBS test was carried out on a universal testing machine at a crosshead speed of 1 mm min(-1) until bond failure occurred. The mean microSBS was regressed on the mean Vickers hardness number (VHN) using a weighted regression analysis in order to explore the relationship between enamel hardness and microSBS. The weights used were the inverse of the variance of the microSBS means. Neither separate correlation analyses for each adhesive nor combined regression analyses showed a significant correlation between the VHN and the microSBS. These results suggest that the microSBS of the self-etch adhesive systems are not influenced by enamel surface microhardness.

Parenteral nutrition-associated cholestasis (PNAC) and liver disease have been associated with soybean oil-based intravenous fat emulsions (IVFEs). The benefit of fish oil-based IVFEs in the reversal of parenteral nutrition (PN)-associated liver damage includes allowing for longer PN duration without immediate need for bowel or liver transplantation. The present case involves an infant born with short bowel syndrome (SBS) requiring long-term PN with development of PNAC and subsequent administration of a fish oil-based IVFE. An infant born with SBS was initiated on PN and enteral feeds. After failed enteral progression, bowel lengthening by serial transverse enteroplasty (STEP) resulted in postoperative ileus with delayed enteral feeding for 4 weeks. The administration of long-term PN led to development of PNAC, resulting in initiation of a fish oil-based IVFE. After 4 months, the cholestasis had resolved. Despite the STEP, at 16 months, the child required bowel tapering due to inability to advance enteral feeding. Fish oil-based IVFE was effectively used to reverse PNAC in a child with SBS. Despite early STEP, the patient was not able to tolerate enteral feedings and required bowel tapering. This case illustrates that early surgical intervention did not allow for improved feed tolerance. This resulted in a significant period without enteral nutrition, leading to development of cholestasis. The use of fish oil-based IVFE may permit a longer duration of PN administration without the development of cholestasis or liver disease, allowing for longer time for bowel adaptation prior to the need for surgical intervention. © 2016 American Society for Parenteral and Enteral Nutrition.

Secondary bilateral synchrony (SBS) indicates bilaterally synchronous epileptiform discharges arising from a focal cortical origin. The present study aims to investigate SBS in partial epilepsy with regard to surgical outcomes and intracranial EEG findings. We retrospectively reviewed consecutive patients who underwent epilepsy surgery following extraoperative intracranial electroencephalography (EEG) study from 2008 to 2012. The presence of SBS was determined based upon the results of scalp EEG monitoring performed for presurgical evaluations. We reviewed scalp EEG, neuroimaging, intracranial EEG findings, and surgical outcomes in patients with SBS. We found 12 patients with SBS who were surgically treated for intractable partial epilepsy. Nine (75%) patients had lateralized ictal semiology and only two (16.6%) patients showed localized ictal onset in scalp EEG. Brain MRI showed epileptogenic lesion in three (25%) patients. Intracranial EEG demonstrated that ictal onset zone was widespread or non-localized in six (50%) patients. Low-voltage fast activity was the most common ictal onset EEG pattern. Rapid propagation of ictal onset was noted in 10 (83.3%) patients. Eleven patients underwent resective epilepsy surgery and only two patients (18.2%) achieved seizure-freedom (median follow-up 56 months). MRI-visible brain lesions were associated with favorable outcomes (p=0.024). Patients with SBS, compared to frontal lobe epilepsy without SBS, showed lesser localization in ictal onset EEG (p=0.029) and more rapid propagation during evolution of ictal rhythm (p=0.015). The present results suggested that resective surgery for partial epilepsy with SBS should be decided carefully, especially in case of nonlesional epilepsy. Poor localization and rapid spread of ictal onset were prominent in intracranial EEG, which might contribute to incomplete resection of the epileptogenic zone and poor surgical outcomes.

The shear bond strength (SBS) can be increased by removing protein pellicles from the enamel surface by deproteinization using 5.25% sodium hypochlorite (NaOCl). The SBS of a self-etch primer is lower than that of a total etch primer; nonetheless, it prevents white spot lesions. This study aimed to assess the SBS of the Anyetch (AE) total etch primer and FL-Bond II Shofu (FL) self-etch primer after enamel deproteinization using 5.25% NaOCl. Forty eight human maxillary first premolars were extracted, cleaned, and divided into four groups. In group A, brackets were bonded to the enamel without deproteinization before etching (A1: 10 teeth using total etch primer (AE); A2: 10 teeth using self-etch primer (FL)). In group B, brackets were bonded to the enamel after deproteinization with 5.25% NaOCl before etching (B1: 10 teeth using total etch primer (AE); B2: 10 teeth using self-etch primer (FL)). Brackets were bonded using Transbond XT, stored in artificial saliva for 24 h at 37°C, mounted on acrylic cylinders, and debonded using a Shimadzu AG-5000 universal testing machine. There were no significant differences in SBS between the total etch (AE) groups (p > 0.05) and between the self-etch (FL) groups (p > 0.05). There were significant differences in SBS between groups A and B. The mean SBS for groups A1, A2, B1, and B2 was 12.91±3.99, 4.46±2.47, 13.06±3.66, and 3.62±2.36 MPa, respectively. Deproteinization using NaOCl did not affect the SBS of the total etch primer (AE) group; it reduced the SBS of the self-etch primer (FL) group, but not with a statistically significant difference.

Step-by-step variability of swing phase trajectory area during steady state walking at a range of speeds

Hurt, Christopher P.; Brown, David A.

2018-01-01

Background Step kinematic variability has been characterized during gait using spatial and temporal kinematic characteristics. However, people can adopt different trajectory paths both between individuals and even within individuals at different speeds. Single point measures such as minimum toe clearance (MTC) and step length (SL) do not necessarily account for the multiple paths that the foot may take during the swing phase to reach the same foot fall endpoint. The purpose of this study was to test a step-by-step foot trajectory area (SBS-FTA) variability measure that is able to characterize sagittal plane foot trajectories of varying areas, and compare this measure against MTC and SL variability at different speeds. We hypothesize that the SBS-FTA variability would demonstrate increased variability with speed. Second, we hypothesize that SBS-FTA would have a stronger curvilinear fit compared with the CV and SD of SL and MTC. Third, we hypothesize SBS-FTA would be more responsive to change in the foot trajectory at a given speed compared to SL and MTC. Fourth, SBS-FTA variability would not strongly co-vary with SL and MTC variability measures since it represents a different construct related to foot trajectory area variability. Methods We studied 15 nonimpaired individuals during walking at progressively faster speeds. We calculated SL, MTC, and SBS-FTA area. Results SBS-FTA variability increased with speed, had a stronger curvilinear fit compared with the CV and SD of SL and MTC, was more responsive at a given speed, and did not strongly co-vary with SL and MTC variability measures. Conclusion SBS foot trajectory area variability was sensitive to change with faster speeds, captured a relationship that the majority of the other measures did not demonstrate, and did not co-vary strongly with other measures that are also components of the trajectory.

Different in-vitro studies have reported various results regarding shear bond strength (SBS) of orthodontic brackets when SEP technique is compared to conventional system. This in-vivo study was designed to compare the effect of conventional acid-etching and self-etching primer adhesive (SEP) systems on SBS and debonding characteristics of metal and ceramic orthodontic brackets. 120 intact first maxillary and mandibular premolars of 30 orthodontic patients were selected and bonded with metal and ceramic brackets using conventional acid-etch or self-etch primer system. The bonded brackets were incorporated into the wire during the study period to simulate the real orthodontic treatment condition. The teeth were extracted and debonded after 30 days. The SBS, debonding characteristics and adhesive remnant indices (ARI) were determined in all groups. The mean SBS of metal brackets was 10.63±1.42 MPa in conventional and 9.38±1.53 MPa in SEP system, (P=0.004). No statistically significant difference was noted between conventional and SEP systems in ceramic brackets. The frequency of 1, 2 and 3 ARI scores and debonding within the adhesive were the most common among all groups. No statistically significant difference was observed regarding ARI or failure mode of debonded specimens in different brackets or bonding systems. The SBS of metal brackets bonded using conventional system was significantly higher than SEP system, although the SBS of SEP system was clinically acceptable. No significant difference was found between conventional and SEP systems used with ceramic brackets. Total SBS of metal brackets was significantly higher than ceramic brackets. Due to adequate SBS of SEP system in bonding the metal brackets, it can be used as an alternative for conventional system.

The purpose of the American Cancer Society/American Society of Clinical Oncology Breast Cancer Survivorship Care Guideline is to provide recommendations to assist primary care and other clinicians in the care of female adult survivors of breast cancer. A systematic review of the literature was conducted using PubMed through April 2015. A multidisciplinary expert workgroup with expertise in primary care, gynecology, surgical oncology, medical oncology, radiation oncology, and nursing was formed and tasked with drafting the Breast Cancer Survivorship Care Guideline. A total of 1,073 articles met inclusion criteria; and, after full text review, 237 were included as the evidence base. Patients should undergo regular surveillance for breast cancer recurrence, including evaluation with a cancer-related history and physical examination, and should be screened for new primary breast cancer. Data do not support performing routine laboratory tests or imaging tests in asymptomatic patients to evaluate for breast cancer recurrence. Primary care clinicians should counsel patients about the importance of maintaining a healthy lifestyle, monitor for post-treatment symptoms that can adversely affect quality of life, and monitor for adherence to endocrine therapy. Recommendations provided in this guideline are based on current evidence in the literature and expert consensus opinion. Most of the evidence is not sufficient to warrant a strong evidence-based recommendation. Recommendations on surveillance for breast cancer recurrence, screening for second primary cancers, assessment and management of physical and psychosocial long-term and late effects of breast cancer and its treatment, health promotion, and care coordination/practice implications are made.This guideline was developed through a collaboration between the American Cancer Society and the American Society of Clinical Oncology and has been published jointly by invitation and consent in both CA: A Cancer Journal for

Sleeping beauties (SBs) in science have been known for few decades; however, it seems that only recently have they become popular. An SB is a publication that "sleeps" for a long time and then almost suddenly awakes and becomes highly cited. SBs present interesting findings in science. Pediatrics research literature has not yet been analyzed for their presence, and 5 pediatrics SBs were discovered in this research. Their prevalence was approximately 0.011%. Some environments or periods are more "SB fertile" than others: 3 of 5 SBs were published in the journal Pediatrics, 4 originated from the United States, and 4 were published in the period from 1992 to 1993. No institutions or authors published more than 1 SB.

Effect of diffraction on stimulated Brillouin scattering from a single laser hot spot

International Nuclear Information System (INIS)

Eliseev, V.V.; Rozmus, W.; Tikhonchuk, V.T.; Capjack, C.E.

A single laser hot spot in an underdense plasma is represented as a focused Gaussian laser beam. Stimulated Brillouin scattering (SBS) from such a Gaussian beam with small f/numbers 2-4 has been studied in a three-dimensional slab geometry. It is shown that the SBS reflectivity from a single laser hot spot is much lower than that predicted by a simple three wave coupling model because of the diffraction of the scattered light from the spatially localized ion acoustic wave. SBS gain per one Rayleigh length of the incident laser beam is proposed as a quantitative measure of this effect. Diffraction-limited SBS from a randomized laser beam is also discussed. copyright 1996 American Institute of Physics

Full Text Available Objective: To compare and evaluate the shear bond strength (SBS of lingual brackets, manufactured by three different processes, that is, laser sintering, milling, and casting, bonded with two different adhesive primers. Materials and Methods: One hundred and twenty premolars were selected, and three types of lingual brackets were used, namely, STB (milling, 7th Generation (casting, and lingualmatrix (laser sintering. Forty brackets per system were used half of which were sandblasted while the other half were used as available. Further, these were subdivided and bonded with Transbond XT primer and adhesive and 3M ESPE Primer and Transbond XT adhesive. Customization of STB and 7th Generation was done by Torque Angulation Reference Guide, Lingualmatrix had bases customized by Computer-aided design/computer-aided manufacturing. SBS was tested with universal testing machine and evaluated for adhesive remnant index (ARI. Results: Statistical analysis showed that surface treatment, use of different primers, method of customization influenced the SBS, and ARI suggested that the fracture occurred between composite and bracket interface. Conclusion: Lingualmatrix bracket showed greater SBS as compared to STB and 7th Generation, sandblasting increased SBS. 3M ESPE primer group showed increased SBS as that bonded with Transbond XT primer. The fracture was between the composite bracket interface.

In 1998 the organization of the International Union of Soil Sciences (IUSS) was renewed to better support national activities. That was also the new start in the operation of the Finnish Society of Soil Sciences, which became affiliated to the IUSS. The society was originally established in 1971 but it remained relatively inactive. Currently, there are around 200 members in the Finnish Society of Soil Sciences. The members of the executive board cover different fields of soil science from geology to microbiology. Mission statement of the society is to promote the soil sciences and their application in Finland, to act as a forum for creation of better links between soil scientists, interested end users and the public, and to promote distribution and appreciation of general and Finnish research findings in soil science. Every second year the society organizes a national two-day long conference. In 2017 the theme 'circular economy' collected all together 57 presentations. The members of the incoming student division carried responsibility in practical co-ordination committee, acting also as session chairs. In the intervening years the society organizes a weekend excursion to neighboring areas. Lately we have explored the use of biochar in landscaping of Stockholm.

Producing Civil Society

DEFF Research Database (Denmark)

Feldt, Liv Egholm; Hein Jessen, Mathias

Since the beginning of the 1990’s, civil society has attracted both scholarly and political interest as the ‘third sphere’ outside the state and the market not only a normatively privileged site of communication and ‘the public sphere’, but also as a resource for democratization processes...... and social cohesion, as well as a provider of welfare services from a welfare state in dire straits. However, such a view upholds a sharp distinction between the three sectors and their distinct logic. This article claims that the separation of spheres is a fundamental part of our ‘social imaginary......’ and as such dominates our way of thinking about civil society. Yet, this view hinders the understanding of how civil society is not a pre-existing or given sphere, but a sphere which is constantly produced both discursively, conceptually and practically.

Endoscopic bilateral self-expandable metallic stent (SEMS) placement for malignant hilar biliary obstructions (MHBOs) is technically demanding, and a second SEMS insertion is particularly challenging. A simultaneous side-by-side (SBS) placement technique using a thinner delivery system may mitigate these issues. We aimed to examine the feasibility and efficacy of simultaneous SBS SEMS placement for treating MHBOs using a novel SEMS that has a 5.7-Fr ultra-thin delivery system. Thirty-four patients with MHBOs underwent SBS SEMS placement between 2010 and 2016. We divided the patient cohort into those who underwent sequential (conventional) SBS placement between 2010 and 2014 (sequential group) and those who underwent simultaneous SBS placement between 2015 and 2016 (simultaneous group), and compared the groups with respect to the clinical outcomes. The technical success rates were 71% (12/17) and 100% (17/17) in the sequential and simultaneous groups, respectively, a difference that was significant (P = .045). The median procedure time was significantly shorter in the simultaneous group (22 min) than in the sequential group (52 min) (P = .017). There were no significant group differences in the time to recurrent biliary obstruction (sequential group: 113 days; simultaneous group: 140 days) or other adverse event rates (sequential group: 12%; simultaneous group: 12%). Simultaneous SBS placement using the novel 5.7-Fr SEMS delivery system may be more straightforward and have a higher success rate compared to that with sequential SBS placement. This new method may be useful for bilateral stenting to treat MHBOs.

Nursing in a postemotional society.

Herdman, Elizabeth A

2004-07-01

Globalization is often seen as the final stage in the transition towards a market economy. It is argued that a side-effect of globalization is cultural homogeneity and loss of life world, or 'McDonaldization'. McDonaldization represents the rationalization of society in the quest for extreme efficiency. More recently, Mestrović has argued that the rationalization of emotions has also occurred and that Western societies are entering a postemotional phase. In postemotional societies there has been a separation of emotion from action. The result is synthetic, manufactured emotions manipulated and standardized for mass consumption. In this paper I explore what it means to nurse in a 'postemotional society' and what impact this dulling of the emotions has had on a profession that locates 'care' as its central defining concept. My aim is to generate critical discussion of the shape and direction of contemporary society and the role of nursing within it.

What is the Knowledge Society?

Marin Dinu

2008-02-01

Full Text Available This study sets out to establish conceptual delimitations, more concordant to the theoretical acquisitions with regard to the knowledge society. The author considers it opportune to situate in the center of the definition of the concept of knowledge society the problem of prevalence in the typology of resources. Thus, the knowledge society appears as a form of organization in which scientific knowledge predominates, be that informatics as well. The concordances of essence are discovered through the discerning of the functional relationship knowledge society – global society. In the spectrum of meanings specific to this highway of post-postmodernist configuration of the world, the priorities of the project of the second modernity – the paradigmatic matrix of globalization – are approached. In fact, the study argues in favor of refocusing globalization on the humane, on its distinctive values which substantiate and lend sense to the evolutions of the world. Postreferentiality is the rational expression of humanity coming back to itself.

The Knowledge Society: A Sustainability Paradigm

Directory of Open Access Journals (Sweden)

Naim Hamdija Afgan

2010-10-01

Full Text Available This paper defines the knowledge society as a human structured organisation based on contemporary developed knowledge and representing new quality of life support systems. It implies the need for a full understanding of distribution of knowledge, access to information and the capability to transfer information into a knowledge. The understanding of knowledge is the central challenge when defining a knowledge society. From our present perception of knowledge society, it is of interest to emphasize the role of the knowledge society in future development of human society. The life support systems are essential pillars of human society development. In this respect knowledge society represents a new paradigm for future development and it is strongly correlated to sustainable development. For this reason the sustainability paradigm of knowledge society is a potential frame for human society development leading to social cohesion, economic competitiveness and stability, use of resources and economic development, safeguarding biodiversity and the ecosystem.In order to verify the mutual relation between knowledge society and sustainability, we have to introduce the difference between these two terms. The knowledge society is based on the agglomeration of eco-knowledge, env-knowledge and soc-knowledge, it may be evaluated as the complex knowledge of quality of life support systems. We have to introduce metrics which will allow us to present knowledge as the paradigm of the number of indicators for verifying progress made.Sustainability metrics are designed to consolidate measures of economic, environmental and social performance of any system. It can be understood as a pattern for evaluation of the available knowledge about systems and their performance. In particular the decision-making process for the selection of the system under consideration must be based on the available knowledge. The link between knowledge and sustainability makes it possible for

Risk society and amoral morality

Full Text Available The modern world is the world of change. Modernity changed all aspects of life in width and depth. The changes are so fast and so many people have impression that they are trapped in a multitude of events that they cannot understand nor control. Instead of society as a system, we are talking about society as a network of different relationships of individuals and social groups. Instead of a harmonious society as a space in which the man resides, developing their potential and needs, we are talking about society as a threatening force that destroys everything in its way as 'Moloch' (Giddens, the 'risk society' (Beck in which the doctrine produced in equal measure the conditions for prosperity, but also the risks and destruction; the simulation of society (Baudrillard which glorifies lies and deceit. Instead of society as a community, we are talking about the disappearance of society (Popper. Can we, therefore, rationally understand and express the world, the world of modernity; this world of profound change resembles the maze in which we are lost and wandering without meaning? Starting with Ulrich Beck and his theory of the risk society, the author points out that the way in which the western civilization started, which is imposed as a mandatory form for the rest of the world, leads to amoral morality. The ideology of progress, which is irrational and without a clear vision and clearly defined values, pushes us into an uncertain future of numerous risks and ever growing individualism. Thus we come to the conviction that without common values, collective values, we are lost in this world of risk. Solidarity and trust are the key values for the stable community, but they are non-existent in the risk society dominated by individualism. In the period of uncertainty in the risk society, only religion provides a healthy basis for communal living. Therefore, the way out of the crisis is not in politics, which is placed at the service of the economy, but

Residential landscapes and house societies of the late prehistoric Society Islands

International Nuclear Information System (INIS)

Kahn, J.G.; Kirch, P.V.

2013-01-01

We extend the 'house society' perspective to one of the most complex Eastern Polynesian chiefdoms, the Society Islands. Employing a landscape approach, we argue that competing elites used the flexibility of the 'house society' structure and its landed estates to promulgate and manipulate status differences. Our study documents how the social hierarchy and its ideological underpinnings were materialised in archaeologically visible ways, including investments in residential landscapes, site proxemics, and construction sequences. While communal investments in the landed material estate were staged over a few centuries, investments in the house's ideology and corporate identity were established early on. Differences in house rank afforded some houses greater access to essential resources and facilitated their abilities to maintain and extend their corporate group, while affording them greater access to labor and continued wealth production over time. Our case study exemplifies the significant role that small-scale relations - quotidian interactions within neighborhoods - played as sources of social power. (author). 105 refs., 9 figs., 3 tabs.

Full Text Available The article considers the influence of marketing on the TRANS­formation of a traditional society with its traditional values in a society of consumption. The de­velopment of capitalism inevitably leads to changes in the socio­political order of the whole modern world. This leads to the fact that the disappearance of the traditional elements of culture, crafts, songs and dances, rites, destroyed traditional norms and values, beliefs, moral and ethical values. Instead of the traditional culture is formed by the mass culture, society develops consumption goods and becoming all that you can sell. Marketing is one tool for the formation of a society of consumption, but it also performs other less prominent function transforms the traditional society into a consumer society with its values, mythology, norms and moral principles.

This paper deals with the poorly understood effects of styrene-butadiene-styrene (SBS) copolymer on the bitumen performance. It focuses on determining the impact of various concentrations (e.g., 0, 4, 8, and 12 wt. %) of SBS on the attributes of two types of asphalt namely AP-5 asphalt and solvent deasphalting (SDA) pitch. The unmodified and modified binders were investigated in terms of their chemical compositions, microstructures, thermo-analytical behaviors, and physical properties. The intricate chemical compositions were evaluated by elemental analysis and thin layer chromatography-ionization detection (TLC-FID). Fourier transform infrared (FT-IR) and nuclear magnetic resonance (NMR) spectroscopies, scanning electron microscopy (SEM), and X-ray diffraction (XRD) were utilized to examine the microstructures. Whereas, thermal characteristics were evaluated by thermogravimetric analysis (TGA/DTGA) and differential scanning calorimetry (DSC). The physical behaviors were monitored through the softening point, penetration, viscosity, and ductility tests. The findings showed that the blending of asphalt with different amounts of SBS resulted into different rheological behaviors. This was reflected from the difference in the SARA (i.e., saturates, aromatics, resins, and asphaltenes) compositions and colloidal instability indexes of the modified asphalts. SEM exhibited a continuous asphalt phase with distributed SBS particles, a continuous polymer phase with distributed asphalt globules, or two interconnected continuous phases. FT-IR, {sup 1}H {sup 13}C NMR, and XRD data revealed that the AP-5 asphalt and SDA pitch experienced a number of distinct structural changes. TGA/DSC studies determined the occurrence of diverse events during thermal treatment. It is concluded that the degree of SBS modification depends strongly on SARA composition and polymer content. If the polymers are molded at higher concentrations along with aromatics-rich SDA pitches, then the mixtures

Evolving society and mental health

Dipesh Bhagabati

2016-07-01

Full Text Available Numerous issues related to culture, occupation, gender, caste, and health, to name a few, have faced harshness of society from time immemorial. Reasons are debatable, ranging from somewhat understandable to completely unacceptable. There is no doubt that society is dynamic and it has changed its view on many of the issues with passing time. Mental health is one such issue which society has neglected for quite a long time. Even today, mental health and mentally ill people face stigma and discrimination in their family, society, and at their workplace. People do not feel comfortable talking about mental health, even if they know that there cannot be any health without a healthy mind. But, as Albert Einstein has said “learn from yesterday, live for today, and hope for tomorrow”, everything is not lost. The mentally ill patients who were once abandoned and left on their own have now started to get humane care and attention. This article discusses this very pertinent topic of changing society and mental health.

We examined shear bond strengths (SBSs) of various tooth-coating-materials including the experimental materials to dentin and demineralization resistance of a fractured adhesive surface after the SBS testing. Three resin-type tooth-coating-materials (BC, PRG Barrier Coat; HC, Hybrid Coat II; and SF, Shield force plus) and two glass-ionomer-type tooth-coating-materials (CV, Clinpro XT Varnish; and FJ, Fuji VII) were selected. The experimental PRG Barrier Coat containing 0, 17, and 33 wt% S-PRG filler (BC0, BC17, and BC33, respectively) were developed. Each tooth-coating-material was applied to flattened dentin surfaces of extracted human teeth for SBS testing. After storing in water for 32 days with 4000 thermal cycling, the specimens were subjected to the SBS test. Specimens after SBS testing were subjected to a pH cycling test, and then, demineralization depths were measured using a polarized-light microscope. ANOVA and Tukey's HSD test were used for statistical analysis. The SBS value of FJ and CV was significantly lower than those of other materials except for BC (p coating-materials demonstrated significantly higher SBS for dentin than the glass-ionomer-type tooth-coating-materials; however, they were inferior to the glass ionomer-type tooth-coating-materials in regards to the acid resistance of the fractured adhesion surface.

Domestic violence, deportation, and women's resistance: notes on managing inter-sectionality.

Science.gov (United States)

Sen, P

1999-02-01

This article describes the work of Southall Black Sisters (SBS), a small women's group in London that engages in political lobbying, activism, and case work, largely with Asian women immigrants seeking an escape from domestic violence. The strategies that SBS uses include: maintaining a strong link between its case work and the larger policy and social practices that make it difficult for women to counter domestic violence effectively; challenging multiple forms of oppression (based on gender, race, ethnicity, and the patriarchy) simultaneously; and networking with a range of other organizations to accomplish specific tasks. Thus, SBS's work for social change challenges the following: the prevailing culture that permits violence against women to be endemic; the construction and delivery of services to abused women that fail to meet the needs of Asian immigrants with little command of English; and the overriding legal and policy context. In particular, SBS clients face difficulties because the UK's immigration rules require incoming spouses to remain married for a year in order to stay in the country. During this period, incoming spouses are denied the very welfare benefits that provide funding for abused women in shelters. SBS case work includes counseling, arranging accommodations, finding legal counsel, and supporting clients through legal processes. SBS draws on its case work to inform its lobbying and to give a voice to victims of domestic violence.

Abortion in a just society.

Science.gov (United States)

Hunt, M E

1993-01-01

A female Catholic theologian imagines a just society that does not judge women who decide to undergo an abortion. The Church, practitioners, and the courts must trust that women do make person-enhancing choices about the quality of life. In the last 15 years most progress in securing a woman's right to abortion has been limited to white, well-educated, and middle or upper middle class women. A just society would consider reproductive options a human right. Abortion providers are examples of a move to a just society; they are committed to women's well-being. There are some facts that make one pessimistic about achieving abortion in a just society. The US Supreme Court plans to review important decisions establishing abortion as a civil right. Further, some men insist on suing women who want to make their own reproductive decisions--an anti-choice tactic to wear away women's right to reproductive choice. Bombings of abortion clinics and harassment campaigns by anti-choice groups are common. These behaviors strain pro-choice proponents emotionally, psychically, and spiritually. Their tactics often lead to theologians practicing self-censorship because they fear backlash. Abortion providers also do this. Further, the reaction to AIDS is that sex is bad. Anti-abortion groups use AIDS to further their campaigns, claiming that AIDS is a punishment for sex. Strategies working towards abortion in a just society should be education and persuasion of policymakers and citizens about women's right to choose, since they are the ones most affected by abortion. Moreover, only women can secure their rights to abortion. In a just society, every health maintenance organization, insurance company, and group practice would consider abortion a normal service. A just society provides for the survival needs of the most marginalized.

Zhao, Yao; Yu, Lu-Le; Weng, Su-Ming; Ren, Chuang; Liu, Chuan-Sheng; Sheng, Zheng-Ming

2017-09-01

The nonlinear coupling between stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS) of intense laser in underdense plasma is studied theoretically and numerically. Based upon the fluid model, their coupling equations are derived, and a threshold condition of plasma density perturbations due to SBS for the inhibition of SRS is given. Particle-in-cell simulations show that this condition can be achieved easily by SBS in the so-called fluid regime with kLλDDebye length [Kline et al., Phys. Plasmas 13, 055906 (2006)]. SBS can reduce the saturation level of SRS and the temperature of electrons in both homogeneous and inhomogeneous plasma. Numerical simulations also show that this reduced SRS saturation is retained even if the fluid regime condition mentioned above is violated at a later time due to plasma heating.

Full Text Available Social structures are changing. The industrial society is a hierarchical pyramid with separate social classes and the law of limited social mobility. The social status tended to be stable and was transmitted from parents to children. The information society, the knowledge society, the society in change and the risk society, is a turmoil of centripetal and centrifugal social forces. The social status of each individual, ranging from the highest ­ with their place in the very heart of the society­ to the lowest, is temporary. The main production resource in the accelerated economy of the information society is knowledge. Renewing competences is essential in order to preserve one’s social status in the social spiral; lagging behind in knowledge and in personal growth , on the other hand, shoves one off to the margins of society. The way back up to a more prestigious position can be achieved through education. Education systems differ from state to state. Some are losing their legitimacy since they fail to train young people for new methods of work and survival; they are an obstacle to the development of the most immanent properties in the new society, as e.g., innovativeness, independence, decision­making ability, creativity. If young people drop out from school too early, before they complete a four­year secondary school, they are surrendered to the street and crime. Manual workers are being discarded on a large scale to find themselves on the margins of society, among the "service proletariat" depending on the handouts of the welfare state. Whereas the GNP is increasing, the wealth redistribution stick to the old formulas and are widening the gap between the poor and the rich. The information society is opening up countless new opportunities, but it is also bringing new responsibilities. Work is becoming more humane, with the "brain" winning over "brawn".

Full Text Available The Society of Physical sciences (phisycs, chemistry and mineralogy has been an important Romanian scientific society since its establishment, in 1890 until the middle of the twentieth century. This paper seeks to provide an analysis of its activity in the first two decades of existence, a less studied period, namely how its enterprises contributed to the dissemination and spread of the latest scientific ideas within Romania’s culture. The society was founded at the initiative of some of the most proeminent Romanian scientists of that period and, until the end of the nineteenth century, it expanded its sphere of activity by including sections on mathemathics and natural history. Therefore, its activity, exemplified by public conferences, presentation of members’ personal scientific endeavors, intellectual debates or scientific missions, reflected the general development of physical sciences in Romania in that epoch. This research is based mostly on a close scrutiny of society’s scientific journal.

Full Text Available ttendees will learn about the research and development which will be effected by scientists in the branch of Conscience Society creation in next decades of XXI century. Conscience is usually seen as linked to a morality inherent in all humans, to a beneficent universe and/or to divinity. It is increasingly conceived of as applying to the world as a whole and as a main feature of conscience society. It has motivated its numerous models, characteristics and functions of Conscience for creation the societal intelligent adaptable information systems in Conscience Society. The moral life is a vital part for the world to maintain a Conscience (civilized Society, so always keep in mind to: accept differences in others; respond promptly to others; leave some "free" time; care about others as if they were you; treat everyone similarly; never engage in violent acts; have an inner sense of thankfulness; have a sense of commitment. Creativity is a result of brain activity which differentiates individuals and could ensure an important competitive advantage for persons, for companies, for Society in general, and for Conscience Society in special. Very innovative branches – like software industry, computer industry, car industry – consider creativity as the key of business success. Natural Intelligence’ Creativity can develop basic creative activities, but Artificial Intelligence’ Creativity, and, especially, Conscience Intelligence’ Creativity should be developed and they could be enhanced over the level of Natural Intelligence. The basic idea for present communication represent the research results communicated at the last two annual AESM conferences [1] [2].

Based on the frequent application of composite resins as tooth-colored fillings, this method is considered a viable alternative to dental amalgam. However, this method has the low bond strength of the composite to dentin. To solve this issue, various dental adhesive systems with different characteristics have been developed by dentistry experts. To assess the effect of an additional layer of unfilled resin in self-etch and total-etch dentin adhesives on the shear bond strength (SBS) of composite to dentin. Moreover, we assessed the effects of sample storage in artificial saliva on the SBS of composite to dentin. Methods: This experimental study was conducted on 160 freshly extracted human first or second premolar teeth, which were randomly divided into 16 groups. The teeth were prepared from Mashhad University of Medical Sciences, Mashhad, Iran (2008-2009). Scotchbond Multi-purpose (SBMP), single bond (SB), Clearfil SE Bond, and Clearfil S3 Bond were applied to dentin surface with or without the placement of hydrophobic resin (Margin Bond) in accordance with the instructions of the manufacturers. To expose the coronal dentin, the teeth were abraded with 600 grit SiC paper. Immediately after restoration, half of the samples were tested in terms of SBS, while the other samples were evaluated in terms of SBS after three months of storage in artificial saliva. SBS rates of dental composites evaluated by universal testing machine and samples were studied by optical stereomicroscopy to verify the failure type. Data analysis was performed in SPSS V.16 using Kolmogorov-Smirnov test, independent-samples t-test, ANOVA, and Duncan's logistic regression test. In this study, a significant reduction was observed in the SBS rates of SB and S3 bond adhesive systems after storage with and without hydrophobic resin (p>0.000). Without storage in normal saline, a significant increase was observed in the SBS rate of the SE bond (p=0.013). In addition, SBS rate of SBMP significantly

Aims: Evaluate shear bond strength (SBS values of different dental adhesives on Erbium:Yttrium Aluminum Garnet (Er:YAG laser prepared enamel and to evaluate possible etching patterns correlations between dental adhesives and SBS values. Subjects and Methods: One hundred bovine incisors were randomly assigned to SBS tests on enamel (n = 15 and to enamel morphology analysis ( n = 5 after Er:YAG laser preparation as follows: Group I - 37% phosphoric acid (PA+ ExciTE® ; Group II - ExciTE® ; Group III - AdheSE® self-etching; Group IV - FuturaBond® no-rinse. NR; Group V - Xeno® V. Teeth were treated with the adhesive systems and subjected to thermal cycling. SBS were performed in a universal testing machine at 5 mm/min. Statistical Analysis Used: One-way ANOVA and post-hoc tests (p < 0.05. For the morphology evaluation, specimens were immersed in Ethylenediamine tetraacetic acid (EDTA and the etching pattern analyzed under Scanning Electron Microscope (SEM. Results: Mean bond strengths were Group I - 47.17 ± 1.61 MPa (type I etching pattern; Group II - 32.56 ± 1.64 MPa, Group III - 29.10 ± 1.34 MPa, Group IV - 23.32 ± 1.53 MPa (type III etching pattern; Group V - 24.43 MPa ± 1.55 (type II etching pattern. Conclusions: Different adhesive systems yielded significantly different SBSs. Acid etching significantly increased the adhesion in laser treated enamel. No differences in SBS values were obtained between AdheSE® and ExciTE® without condition with PA. FuturaBond® NR and Xeno® V showed similar SBS, which was lower in comparison to the others adhesives. No correlation between enamel surface morphology and SBS values was observed, except when PA was used.

Robust, Brillouin Active Embedded Fiber-Is-The-Sensor System in Smart Composite Structures

Yu, Chung

1996-01-01

Extensive review of our proposed sensing scheme, based mainly on the forward Guided Acoustic Wave Brillouin Scattering (GAWBS) with backward stimulated Brillouin scattering (sBs) as an auxiliary scheme for system fault tolerance has been completed during this project period. This preliminary study is conducted for a number of reasons. The most significant reasons lie in the essential capability of the system to measure temperature and pressure. These two measurands have been proposed to be sensed by sBs in our proposal. Temperature and pressure/strain are important measurands in structural monitoring, so that the effectiveness of sensing by sBs needs to be further examined. It has been pointed out initially that sBs shift will be dependent on temperature and pressure/strain simultaneously. The shift versus temperature or strain is linear. Now, the question is how can these two measurands be separated when sBs is used to sense an environment, in which both temperature and strain are changing simultaneously. Typical sBs shift plotted versus strain and varying temperature is shown in Fig. 1. As is clear, a fiber initially stressed will relax with rising temperature. This is verified by a displacement to the right with rising temperature of the sBs shift vs strain curves in the figure. A way to circumvent this ambiguity is by employing two fibers, one pre-stressed and the other is a free fiber. The latter will measure temperature and subtracting data in the latter fiber from those of the former will give us net strain readings. This is a laborious approach, since it involves the use of two identical fibers, and this is hard to accomplish, especially when many sensors are needed. Additional multiplexing of the data stream for data subtraction becomes a necessity.

Parameters influencing the aerosol capture performance of the Submerged-Bed Scrubber

Ruecker, C.M.; Scott, P.A.

The Submerged-Bed Scrubber (SBS) is a novel air cleaning device that has been investigated by Pacific Northwest Laboratory (PNL) for scrubbing off gases from liquid-fed ceramic melters used to vitrify high-level waste (HLW). The concept for the SBS was originally conceived at Hanford for emergency venting of a reactor containment building. The SBS was adapted for use as a quenching scrubber at PNL because it can cool the hot melter off gas as well as remove over 90% of the airborne particles, thus meeting the minimum particulate decontamination factor (DF) of 10 required of a primary scrubber. The experiments in this study showed that the submicron aerosol DF for the SBS can exceed 100 under certain conditions. A conventional device, the ejector-venturi scrubber (EVS), has been previously used in this application. The EVS also adequately cools the hot gases from the melter while exhibiting aerosol removal DFs in the range of 5 to 30. In addition to achieving higher DFs than the EVS, however, the SBS has the advantage of being a passive system, better suited to the remote environment of an HLW processing system. The objective of this study was to characterize the performance of the SBS and to improve the aerosol capture efficiency by modifying the operating procedure or the design. A partial factorial experimental matrix was completed to determine the main effects of aerosol solubility, inlet off-gas temperature, inlet off-gas flow rate, steam-to-air ratio, bed diameter and packing diameter on the particulate removal efficiency of the SBS. Several additional experiments were conducted to measure the influence of the inlet aerosol concentration and scrubbing-water concentration on aerosol-removal performance. 33 refs., 17 figs., 14 tabs

Full Text Available Introduction. Compoglass is a trade mark of dental compomers and because of its partially resinus structure, surface conditioning of dental surfaces is needed for a better bonding process. In this study, the effect of enamel and dentin conditioning procedure on shear bond strength (SBS of compoglass to tooth surfaces was studied. Methods. four groups each one including 11 sound premolars were chosen and their surfaces were prepared as following groups: group1, unconitioned dentin; group 2, dentin conditioning with phosphoric acid 35%; group 3, dentin conditioning with polyacrylic acid 20% group 4, unconditioning enamel; group 5, enamel conditioning with phosphoric acid 35%; and group 6, enamel conditioning with polyacrylic acid 20%. Compoglass was bonded to prepared surfaces and after fixation of the samples in acrylic molds, all samples were tested under shear force of instron testing machine at a rate of 1 mm/min speed. Results. The mean SBS obtained in these 6 groups were 6.207, 8.057, 10.146, 25.939 and 11.827 mpa. the mode of fracture also studied using a streomicroscope. Statistical analysis of the results showed that the maximum SBS obtained in group 5 and the lowest SBS about 6.207 mpa obtained in group 1. Despite increase in SBS group 2 and 3, there was no statistical differncies between group 1, 2 and 3. Discussion. Based on results of this study, conditioning of enamel and dentin surface due to improve SBS is recommeneded.

To determine the in vitro shear bond strengths (SBS) of zirconia ceramic to resin composite after various primer treatments. Forty zirconia ceramic (Zeno, Wieland Dental) specimens (10 mm in diameter and 2 mm thick) were prepared, sandblasted with 50 μm alumina, and divided into four groups (n = 10). Three experimental groups were surface treated with three primers; CP (RelyX Ceramic Primer, 3M ESPE), AP (Alloy Primer, Kuraray Medical), and MP (Monobond Plus, Ivoclar Vivadent AG). One group was not treated and served as the control. All specimens were bonded to a resin composite (Filtek Supreme XT, 3M ESPE) cylinder with an adhesive system (Adper Scotchbond Multi-Purpose Plus Adhesive, 3M ESPE) and then stored in 100% humidity at 37°C for 24 h before SBS testing in a universal testing machine. Mean SBS (MPa) were analyzed with one-way analysis of variance (ANOVA) and the Tukey's Honestly Significant Difference (HSD) test (α = 0.05). Group AP yielded the highest mean and standard deviation (SD) value of SBS (16.8 ± 2.5 MPa) and Group C presented the lowest mean and SD value (15.4 ± 1.6 MPa). The SBS did not differ significantly among the groups (P = 0.079). Within the limitations of this study, the SBS values between zirconia ceramic to resin composite using various primers and untreated surface were not significantly different.

Shaken Baby Syndrome (SBS), currently functioning as Abusive Head Trauma (AHT), is a form of violence against children mainly under 2 years of age. The number of SBS might be underestimated, as many cases of violence remain unreported. The aim of the study was evaluation of the state of knowledge of the SBS phenomenon, its scale and diagnostic methods among parents, medical staff and medical students. 639 people were examined: 39% of parents, 32,5% medical staff members and 28,5% of medical students. 82% were women. The average age was 34,9 years (SD=9,78). 70% of them had children. The research tool was an anonymous survey. The 34 questions concerned numerous aspects of violence against children as well as knowledge about SBS. According to 90% of the interviewees shaking a baby may be dangerous but 43% have ever heard about shaken baby syndrome. 'SBS is a form of violence' said 88% of respondents but 57% realize that one-time shaking can lead to death and only 19% indicated men as aggressors. 16% of medical staff members did not know how long it takes for the consequences of shaking a baby to be revealed. Majority of the medical staff members working with children have never heard about SBS. Only half of the surveyed understands the connection of shaking with vision loss or child's death. Among the long-term consequences of shaking a baby the greatest knowledge concerns emotional consequences of shaking.

The Hanford Waste Treatment and Immobilization Plant (WTP) will generate an off-gas treatment system secondary liquid waste stream [submerged bed scrubber (SBS) condensate], which is currently planned for recycle back to the WTP Low Activity Waste (LAW) melter. This SBS condensate waste stream is high in Tc-99, which is not efficiently captured in the vitrified glass matrix [1]. A pre-conceptual engineering study was prepared in fiscal year 2012 to evaluate alternate flow paths for melter off-gas secondary liquid waste generated by the WTP LAW facility [2]. This study evaluated alternatives for direct off-site disposal of this SBS without pre-treatment, which mitigates potential issues associated with recycling. This study [2] concluded that SBS direct disposal is a viable option to the WTP baseline. The results show: - Off-site transportation and disposal of the SBS condensate is achievable and cost effective. - Reduction of approximately 4,325 vitrified WTP Low Activity Waste canisters could be realized. - Positive WTP operational impacts; minimal WTP construction impacts are realized. - Reduction of mass flow from the LAW Facility to the Pretreatment Facility by 66%. - Improved Double Shell Tank (DST) space management is a benefit.

The objective of this study is to investigate placental telomere shortening in unexplained stillbirths (SBs) as an indication of premature senescence. Placentas were collected from 42 unexplained SB (>22 weeks), 43 term and 15 preterm live births, at the Policlinico Hospital of Modena (Italy). DNA extracted from placentae was studied for telomere length by real time PCR. Standard curves were generated for telomere lengths from single copy gene amplifications using a reference DNA. The telomere length for each sample was derived based on the ratio of telomere length between the sample and single copy gene standard (T/S ratio). The mean ratio of placental telomere in term live births was 5.181 ± 3.841. A twofold decrease in telomere length was seen in SBs (over all 2.455 ± 1.239; p PTBs) (6.382 ± 5.525; p < 0.01), whereas SBs telomere length were similar to those of preterm premature rupture of membranes (pPROM) (3.296 ± 3.599; p = ns). Substantial reduction in telomere length in SBs is indicative of placental senescence. These data provide mechanistic insights that premature aging may lead to placental dysfunction as an initiator of fetal demise in unexplained SBs.

Full Text Available Little is known about the effect of specimen preparation and testing protocols on the micro-shear bond strength (μSBS results. To evaluate whether variations in polyethylene rod use affect (μSBS. Human dentin disks were randomly distributed into six groups (: polyethylene tube (3 levels and adhesive system (2 levels. In Group 1, polyethylene tubes filled with polymerized composite were placed on adhesive covered surfaces. Tubes were removed 24 h after water storage, leaving the rods only. In Group 2, the same procedure was performed; however, tubes were kept in place during testing. In Group 3, composite rods without tubes were placed on adhesive covered dentin. In all groups, adhesives were photoactivated after positioning filled tubes/rods on adhesive covered surfaces. Specimens were tested under shear mode and the data subjected to a two-way ANOVA and Tukey’s tests. Groups 1 and 2 resulted in statistically similar mean μSBS (; however, a greater number of pretest failures were observed for Group 1. Higher μSBS values were detected for Group 3, irrespective of adhesive system used (. Removing the polyethylene tube before composite rod is placed on dentin affects μSBS values.

Human Capital Management and Accountability of Social Enterprise

Full Text Available The emergence of social business enterprises has been attributed to the increased demand for sustainability among the non-profit organisations (NPOs due to diminishing funding from traditional sources and increased competition for the scarce resources. To date, there is growing interest on social businesses (SBs as innovation in providing public services that contributes to the social wellbeing of community. This in turn can be linked directly or indirectly to economic development as the sustainability level of the country is measured specifically towards the development of human capital and solving the social problems rather than the economics alone. Indeed, having both economic and non-economic aims, SBs would be the potential solutions to address a range of societal issues and increase the efficiency and quality of public sector services that focus on equitable growth with ecological sustainability. Therefore, it is important to explore the relationship between capability of SBs and the social impact created. This paper explores on capability based on human capital management and social impact or value created through SBs. This is expected to provide some insights on the sustainability and credibility of SBs to support the government efforts in moving towards high nation income.

pF3D Simulations of Large Outer-Beam Brillouin Scattering from NIF Rugby Hohlraums

Langer, Steven; Strozzi, David; Chapman, Thomas; Amendt, Peter

2015-11-01

We assess the cause of large outer-beam stimulated Brillouin scattering (SBS) in a NIF shot with a rugby-shaped hohlraum, which has less wall surface loss and thus higher x-ray drive than a cylindrical hohlraum of the same radius. This shot differed from a prior rugby shot with low SBS in three ways: outer beam pointing, split-pointing of the four beams within each outer-beam quadruplet, and a small amount of neon added to the hohlraum helium fill gas. We use pF3D, a massively-parallel, paraxial-envelope laser plasma interaction code, with plasma profiles from the radiation-hydrodynamics code Lasnex. We determine which change between the two shots increased the SBS by adding them one at a time to the simulations. We compare the simulations to experimental data for total SBS power, its spatial distribution at the lens, and the SBS spectrum. For each shot, we use profiles from Lasnex simulations with and without a model for mix at the hohlraum wall-gas interface.

To compare the shear bond strength (SBS) of rebonded orthodontic metal brackets with different resin removal methods. Forty extracted premolars were chosen as samples and divided into 4 experimental groups. The teeth were bonded with brackets. The brackets from 3 groups were debonded while adhesive remnants were removed from bracket bases by methods of grinding, sandblasting, and direct flaming, respectively and then rebonded. The SBS values of all rebonded brackets were determined after pH cycling experiment for 30 days. Some rebonded bracket bases were selected and observed under scanning electron microscope (SEM). The data was analyzed by one-way ANOVA test using SPSS 13.0 software package. Statistical analysis revealed a significant difference of SBS values among the 4 experimental groups (Pbrackets after resin removal by grinding and sandblasting have a similar SBS compared to the initial brackets adhesive.

ROMANIAN KNOWLEDGE SOCIETY DEVELOPMENT. A PROPOSAL

Mirela CERKEZ

2016-06-01

Full Text Available This article is an argument for the applicability of the Finnish model of knowledge society oriented public policy-making and not a detailed recommendation on the specific steps Romania should make in order to become a knowledge society. The article is elaborated as a synthesis of the Finnish knowledge society oriented public policies and an analysis of the adequacy of policy transfers from Finland to Romania. Data on Romania are not rich as the task of the article is not to make a diagnosis on Romania’s stage of development. Its main contribution consists of the identification of Finnish public measures meant to foster knowledge society that may be a best practice example for Romania. The introductory part briefly introduces the reader into the theoretical understanding of the concept of knowledge society. Then, I argue that there are several types of knowledge societies and Romania should look for European examples given the resemblance of the starting conditions. The main part of the paper presents the Finnish knowledge society development as an experience modeled by public intervention and I mirror these developments with the Romanian case. In the end, I explore the differences between the two countries that may interfere with the application of the Finnish model. Still, my conclusion is that those differences do not make the Finnish model less applicable. The efforts might need to be more intense and the results might show up later.

The behavior of stimulated Brillouin scattering (SBS) and Rayleigh backscattering phenomena, which limit the forward transmission power in modern, ultra-long haul optical communication systems such as dense wavelength division multiplexing systems is analyzed via simulation and experimental investigation of threshold and maximum power. Evolution of SBS, Rayleigh scattering and forward powers are experimentally investigated with a 25 km segment of single mode fiber. Also, a simple algorithm to predict the generation of SBS is proposed where two criteria of power thresholds was used for comparison with experimental data. (paper)

The self-phase locking of a stimulated Brillouin scattering-phase conjugate mirror (SBS-PCM) allows a simple and scalable coherent beam combination of existing lasers. We propose a simple optical system composed of a rotating wedge and a concave mirror to overcome the power limit of the SBS-PCM. Its phase locking ability and the usefulness on the beam-combination laser are demonstrated experimentally. A four-beam combination is demonstrated using this SBS-PCM scheme. The relative phases between the beams were measured to be less than λ/24.7.

Beyond strong and weak: rethinking postdictatorship civil societies.

Science.gov (United States)

Riley, Dylan; Fernández, Juan J

2014-09-01

What is the impact of dictatorships on postdictatorial civil societies? Bottom-up theories suggest that totalitarian dictatorships destroy civil society while authoritarian ones allow for its development. Top-down theories of civil society suggest that totalitarianism can create civil societies while authoritarianism is unlikely to. This article argues that both these perspectives suffer from a one-dimensional understanding of civil society that conflates strength and autonomy. Accordingly we distinguish these two dimensions and argue that totalitarian dictatorships tend to create organizationally strong but heteronomous civil societies, while authoritarian ones tend to create relatively autonomous but organizationally weak civil societies. We then test this conceptualization by closely examining the historical connection between dictatorship and civil society development in Italy (a posttotalitarian case) and Spain (a postauthoritarian one). Our article concludes by reflecting on the implications of our argument for democratic theory, civil society theory, and theories of regime variation.

Full Text Available This paper will analyze the importance and the effects of religion, in Kosovar society. A great part of the paper, will analyze the social and the political relations in Post-War Kosovo. Initially it will elaborate religion and secularism, especially in theoreticall aspect, what impact have these definitions in modern societies. In order to explain what the importance of the religion in Kosovo is, we will focus on analyzing ethnical, social and political relations within Kosovo society. A considerable component of the paper is also, the elaboration of secularism in Kosovo conditions. This implies that the formulation of the problem and the objective of this research, are the substance of the paper’s theme, which is, religion in Kosovo; its definition and the outlook of the Kosovar society on religion. Is Kosovo post-war society more or less religious? That means the elements of Religions and Secularism will be part of the analysis of developments in post-war Kosovo.

AGU is a participant in a U.S. National Science Foundation (NSF)-funded project called Advancing Ways of Awarding Recognition in Disciplinary Societies (AWARDS), which seeks to examine whether gender bias affects selection of recipients of society awards. AGU is interested in learning why there is a higher proportion of female recipients of service and education awards over the past 2 decades. Combined with a lower rate of receipt of research awards, these results suggest that implicit (subconscious) bias in favor of male candidates still influences awardee selection. Six other professional societies (American Chemical Society, American Mathematical Society, American Society of Anesthesiologists, Mathematical Association of America, Society for Neuroscience, and Society for Industrial and Applied Mathematics) are participating in the project. Volunteers from each participant society attended an Association for Women in Science (AWIS)-sponsored workshop in May 2010 to examine data and review literature on best practices for fair selection of society awardees. A draft proposal for implementing these practices will be brought before the AGU Council and the Honors and Recognition Committee at their upcoming meetings.

Gender equality activity in the Bioimaging Society was initiated in 2005 when it joined the Japan Inter-Society Liaison Association Committee for Promoting Equal Participation of Men and Women in Science and Engineering (EPMEWSE). The Gender Equality Committee of the Bioimaging Society is acting on this issue by following the policy of the EPMEWSE, and has also been planning and conducting lectures at annual meetings of the society to gain the understanding, consents, and cooperation of the members of the society to become conscious of gender equality. Women's participation in the society has been promoted through the activities of the Gender Equality Committee, and the number of women officers in the society has since increased from two women out of 40 members in 2005 to five out of 44 in 2013. The activities of the Gender Equality Committee of the Japanese Association of Anatomists (JAA) have just started. There are more than 400 women belonging to the JAA. When these women members join together and collaborate, women's participation in the JAA will increase.

Sustainable Society Formed by Unselfish Agents

Science.gov (United States)

Kikuchi, Toshiko

It has been pointed out that if the social configuration of the three relations (market, communal and obligatory relations) is not balanced, a market based society as a total system fails. Using multi-agent simulations, this paper shows that a sustainable society is formed when all three relations are integrated and function respectively. When agent trades are based on the market mechanism (i.e., agents act in their own interest and thus only market relations exist), weak agents who cannot perform transactions die. If a compulsory tax is imposed to enable all weak agents to survive (i.e., obligatory relations exist), then the fiscal deficit increases. On the other hand, if agents who have excess income undertake the unselfish action of distributing their surplus to the weak agents (i.e., communal relations exist), then trade volume increases. It is shown that the existence of unselfish agents is necessary for the realization of a sustainable society. However, the survival of all agents is difficult in a communal society. In an artificial society, for all agents survive and fiscal balance to be maintained, all three social relations need to be fully integrated. These results show that adjusting the balance of the three social relations well lead to the realization of a sustainable society.

Hemodynamically Unstable Pelvic Trauma is a major problem in blunt traumatic injury. No cosensus has been reached in literature on the optimal treatment of this condition. We present the results of the First Italian Consensus Conference on Pelvic Trauma which took place in Bergamo on April 13 2013. An extensive review of the literature has been undertaken by the Organizing Committee (OC) and forwarded to the Scientific Committee (SC) and the Panel (JP). Members of them were appointed by surgery, critical care, radiology, emergency medicine and orthopedics Italian and International societies: the Italian Society of Surgery, the Italian Association of Hospital Surgeons, the Multi-specialist Italian Society of Young Surgeons, the Italian Society of Emergency Surgery and Trauma, the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care, the Italian Society of Orthopaedics and Traumatology, the Italian Society of Emergency Medicine, the Italian Society of Medical Radiology, Section of Vascular and Interventional Radiology and the World Society of Emergency Surgery. From November 2012 to January 2013 the SC undertook the critical revision and prepared the presentation to the audience and the Panel on the day of the Conference. Then 3 recommendations were presented according to the 3 submitted questions. The Panel voted the recommendations after discussion and amendments with the audience. Later on a email debate took place until December 2013 to reach a unanimous consent. We present results on the 3 following questions: which hemodynamically unstable patient needs an extraperitoneal pelvic packing? Which hemodynamically unstable patient needs an external fixation? Which hemodynamically unstable patient needs emergent angiography? No longer angiography is considered the first therapeutic maneuver in such a patient. Preperitoneal pelvic packing and external fixation, preceded by pelvic binder have a pivotal role in the management of these patients

Juan Soto Ramírez

2012-11-01

Full Text Available Common sense, the thinking of the people par excellence, asserts that: a picture is worth a thousand words. This is a big mistake. The images are not carriers of meanings. The images always go through three basic processes are: production, circulation and reception. These processes are always determined in the time and social space. They are always the result of multiple relationships (social, ideological, political, moral, religious, etc., established with them. Always there are so many elements beyond the image, which determines its meaning. The meaning of an image always depends on the relationships established with it in a historical time and space, socially and culturally determined. The images are never alone. To decrypt their meanings, you must first know the symbolic life of the societies in which they appear. Images do not have a single meaning because it depends on the historical and cultural geography which presents. The images always have a close relationship with the society they were born.

Politicized Civil Society in Bangladesh: Case Study Analyses

Directory of Open Access Journals (Sweden)

Farhat Tasnim

2017-03-01

Full Text Available Although civil society in Bangladesh is recognized for its vibrant performance in social development, it is often criticized for its inability to ensure good governance and democracy. The aim of this paper is to point out the reasons for this failure of civil society. Through performing case studies upon five civil society organizations representing different sector and level of the civil society, the paper concludes that civil society organizations in Bangladesh are often politicized and co-opted by different political parties. In a typical scenario, civil society can provide a counterbalance or even monitor the state both at the national and local level. However, in Bangladesh, often the civil society organizations have compromised their autonomy and politicized themselves to certain political parties or political block. In such a vulnerable position, civil society can hardly play its expected role to ensure good governance and strengthen democracy.

Social Value Orientation and Capitalism in Societies.

Shahrier, Shibly; Kotani, Koji; Kakinaka, Makoto

2016-01-01

Cooperation and competition are core issues in various fields, since they are claimed to affect the evolution of human societies and ecological organizations. A long-standing debate has existed on how social behaviors and preferences are shaped with culture. Considering the economic environment as part of culture, this study examines whether the ongoing modernization of competitive societies, called "capitalism," affects the evolution of people's social preferences and behaviors. To test this argument, we implemented field experiments of social value orientation and surveys with 1002 respondents for three different areas of Bangladesh: (i) rural, (ii) transitional and (iii) capitalistic societies. The main result reveals that with the evolution from rural to capitalistic societies, people are likely to be less prosocial and more likely to be competitive. In a transitional society, there is a considerable proportion of "unidentified" people, neither proself nor prosocial, implying the potential existence of unstable states during a transformation period from rural to capitalistic societies. We also find that people become more proself with increasing age, education and number of children. These results suggest that important environmental, climate change or sustainability problems, which require cooperation rather than competition, will pose more danger as societies become capitalistic.

Borelli, Jessica L; Burkhart, Margaret L; Rasmussen, Hannah F; Brody, Robin; Sbarra, David A

2017-03-01

The secure base script (SBS) framework is one method of assessing implicit internal working models of attachment; recently, researchers have applied this method to analyze narratives regarding relationship experiences. This study examines the associations between attachment avoidance and SBS content when parents recall a positive moment of connection between themselves and their children (relational savoring) as well as their association with parental emotion and reflective functioning (RF). Using a sample of parents (N = 155, 92% female) of young children (53% boys, M age = 12.76 months), we found that parental attachment avoidance is inversely associated with SBS content during relational savoring, and that SBS content is an indirect effect explaining the association between attachment avoidance and postsavoring (positive and negative) emotion as well as avoidance and poststressor RF. Findings have implications for understanding attachment and parenting. © 2017 Michigan Association for Infant Mental Health.

Radiation protection and society

The radiological protection of population, living on the contaminated territories, is actual 10 years after the Chernobyl accident. Eventually, the whole system of countermeasures application is aimed to protect society as a complex community of individuals . The variety of levels of society, i.e. family, settlement on the whole, can be considered as certain harmonic systems differing in their public consciousness levels and lifestyles, this explain the difference in their 'behaviour' in terms of radiation protection and attitude to the information obtained. Each level of society possesses a certain degree of liberty of choice, that finally influence the magnitude and the character of dose distribution within certain population groups. In general, the dose distribution in the settlement can be explained only on the bases of 'family' analysis. This concerns the rural settlement as a society too. All rural settlement can be divided into two or three classes: with low, high and intermediate social features. Small settlements (< 100 persons), where the advanced in age persons with low material income and high degree of natural economy are applied to the first class. This results in higher doses (2-3 fold), than in the settlements with higher social level. The analysis shows that in socially 'waning' settlements the countermeasures are less efficient and the term of their action is shorter. (this class is the largest, About 50% among all the rural settlements). Due to the deterioration of the economic situation in the Republic of Belarus after 1991-1992 resulted in the increase of doses mainly in the habitants first of all of this class of settlements. It seems problematic to increase countermeasures efficiency in this class of settlements without the refuse of the accustomed lifestyle and radical improvement of social-demographic and economic conditions. The present material shows the necessity of the differential approach based on 'society-analysis' in the

Full Text Available Introduction: Sick building syndrome (SBS is a medical condition in which people in a certain buildings suffer from symptoms of illness or feeling unwell. The aim of this study was to determine the frequency of exposure of the employees of public institutions from the city of Osijek to harmful psychosocial factors of the working environment, to assess whether there is a connection between the exposure to these factors and the incidence of SBS symptoms and to clarify the nature of this connection.Methods: This cross-sectional study was conducted during May 2013 among 178 employees of public institutions in the city of Osijek. An anonymous questionnaire which contained questions relating to demographic data and working status of the participants, their exposure to various harmful psychosocial factors of the working environment and occurrence of certain symptoms of SBS among them was used as a research tool.Results: 96.1 % (171/178 of participants were exposed to harmful psychosocial factors of the working environment. Employees exposed to those factors more frequently expressed symptoms of SBS. The incidence and the number of symptoms of SBS among employees simultaneously grew with the increase of the number of harmful psychosocial factors of the working environment to which they were exposed.Conclusion: The study showed positive connection between the exposure to harmful psychosocial factors of the working environment and the incidence of SBS symptoms, highlighting this issue as a very important subject in the field of occupational medicine and health protection in the workplace.

Sleep-related violence and sexual behavior in sleep: a systematic review of medical-legal case reports.

To review systematically medical-legal cases of sleep-related violence (SRV) and sexual behavior in sleep (SBS). We searched Pubmed and PsychINFO (from 1980 to 2012) with pre-specified terms. We also searched reference lists of relevant articles. Case reports in which a sleep disorder was purported as the defense during a criminal trial and in which information about the forensic evaluation of the defendant was provided. Information about legal issues, defendant and victim characteristics, circumstantial factors, and forensic evaluation was extracted from each case. A qualitative-comparative assessment of cases was performed. Eighteen cases (9 SRV and 9 SBS) were included. The charge was murder or attempted murder in all SRV cases, while in SBS cases the charge ranged from sexual touching to rape. The defense was based on sleepwalking in 11 of 18 cases. The trial outcome was in favor of the defendant in 14 of 18 cases. Defendants were relatively young males in all cases. Victims were usually adult relatives of the defendants in SRV cases and unrelated young girls or adolescents in SBS cases. In most cases the criminal events occurred 1-2 hours after the defendant's sleep onset, and both proximity and other potential triggering factors were reported. The forensic evaluations widely differed from case to case. SRV and SBS medical-legal cases did not show apparent differences, except for the severity of the charges and the victim characteristics. An international multidisciplinary consensus for the forensic evaluation of SRV and SBS should be developed as an urgent priority.

Bond Strength of Resin Composite to Dentin with Different Adhesive Systems: Influence of Relative Humidity and Application Time.

Amsler, Fabienne; Peutzfeldt, Anne; Lussi, Adrian; Flury, Simon

2015-06-01

To investigate the influence of relative humidity and application time on bond strength to dentin of different classes of adhesive systems. A total of 360 extracted human molars were ground to mid-coronal dentin. The dentin specimens were treated with one of six adhesive systems (Syntac Classic, OptiBond FL, Clearfil SE Bond, AdheSE, Xeno Select, or Scotchbond Universal), and resin composite (Filtek Z250) was applied to the treated dentin surface under four experimental conditions (45% relative humidity/application time according to manufacturers' instructions; 45% relative humidity/reduced application time; 85% relative humidity/application time according to manufacturers' instructions; 85% relative humidity/reduced application time). After storage (37°C, 100% humidity, 24 h), shear bond strength (SBS) was measured and data analyzed with nonparametric ANOVA followed by Kruskal-Wallis tests and Mann-Whitney U-tests with Bonferroni-Holm correction for multiple testing (level of significance: α = 0.05). Increased relative humidity and reduced application time had no effect on SBS for Clearfil SE Bond and Scotchbond Universal (p = 1.00). For Syntac Classic, OptiBond FL, AdheSE, and Xeno Select there was no effect on SBS of reduced application time of the adhesive system (p ≥ 0.403). However, increased relative humidity significantly reduced SBS for Syntac Classic, OptiBond FL, and Xeno Select irrespective of application time (p ≤ 0.003), whereas for AdheSE, increased relative humidity significantly reduced SBS at recommended application time only (p = 0.002). Generally, increased relative humidity had a detrimental effect on SBS to dentin, but reduced application time had no effect.

The aim of this study was to compare the shear bond strength (SBS) of orthodontic brackets bonded to zirconia surfaces using three different zirconia primers and one silane primer, and subjected to thermocycling. We designed 10 experimental groups following the surface treatment and thermocycling. The surface was treated with one of the following method: no-primer (NP), Porcelain Conditioner (PC), Z-PRIME Plus (ZP), Monobond Plus (MP) and Zirconia Liner Premium (ZL) (n=20). Then each group was subdivided to non-thermocycled and thermocycled groups (NPT, PC, ZPT, MPT, ZLT) (n=10). Orthodontic brackets were bonded to the specimens using Transbond™ XT Paste and light cured for 15 s at 1,100 mW/cm(2). The SBS was measured at a 1 mm/min crosshead speed. The failure mode was assessed by examination with a stereomicroscope and the amount of bonding resin remaining on the zirconia surface was scored using the modified adhesive remnant index (ARI). The SBS of all experimental groups decreased after thermocycling. Before thermocycling, the SBS was ZL, ZP ≥ MP ≥ PC > NP but after thermocycling, the SBS was ZLT ≥ MPT ≥ ZPT > PCT = NPT (p > 0.05). For the ARI score, both of the groups lacking primer (NP and NPT) displayed adhesive failure modes, but the groups with zirconia primers (ZP, ZPT, MP, MPT, ZL, and ZLT) were associated with mixed failure modes. Surface treatment with a zirconia primer increases the SBS relative to no-primer or silane primer application between orthodontic brackets and zirconia prostheses.

Does obesity affect the position of seat belt loading in occupants involved in real-world motor vehicle collisions?

Previous work has shown that the lap belt moves superior and forward compared to the bony pelvis as body mass index (BMI) increases. The goal of this project was to determine whether the location of lap belt loading is related to BMI for occupants who sustained real-world motor vehicle collisions (MVCs). A national MVC database was queried for vehicle occupants over a 10-year period (2003-2012) who were at least 16 years old, restrained by a 3-point seat belt, sitting in the front row, and involved in a front-end collision with a change in velocity of at least 56 km/h. Cases were excluded if there was not an available computed tomography (CT) scan of the abdomen. CT scans were then analyzed using adipose enhancement of 3-dimensional reconstructions. Scans were assessed for the presence a radiographic seat belt sign (rSBS), or subcutaneous fat stranding due to seat belt loading. In scans in which the rSBS was present, anterior and superior displacement of rSBS from the anterior-superior iliac spine (ASIS) was measured bilaterally. This displacement was correlated with BMI and injury severity. The inclusion and exclusion criteria yielded 151 cases for analysis. An rSBS could definitively be identified in 55 cases. Cases in which occupants were older and had higher BMI were more likely to display an rSBS.

The new totalitarian society

Directory of Open Access Journals (Sweden)

Vlajki Emil

2011-01-01

Full Text Available The new totalitarian society is a euphemized expression denoting the New World Order, which in itself denotes the American globalization. The underpinning of this mindset is rationality, which is characteristic of Western civilization. Christianity engendered rationality by introducing it through St. Thomas Aquinas, Aristotle, and especially formal logic. Since it is obvious that religion and logic cannot ultimately be harmonized, this combination has proven lethal in many cases throughout history. For instance, the Inquisition, which, contrary to what happened at scholastic universities, severely berated rational thinking in practice. Catholicism helped carry out genocide against the Jews, and Orthodoxy is in a certain manner tied in with Stalinism. The new totalitarian society is anchored in American Protestantism. On the whole, Christian rationalism is a sphere of science, techniques and technologies efficiently employed to promote the West to the status of a society of plenty and the conception of human rights, which turn into their opposite and irrational behavior of the worst kind. An example of such inhumanity is the attack against Yugoslavia/Serbia in 1999.

Standard deviation index for stimulated Brillouin scattering suppression with different homogeneities.

Science.gov (United States)

Ran, Yang; Su, Rongtao; Ma, Pengfei; Wang, Xiaolin; Zhou, Pu; Si, Lei

2016-05-10

We present a new quantitative index of standard deviation to measure the homogeneity of spectral lines in a fiber amplifier system so as to find the relation between the stimulated Brillouin scattering (SBS) threshold and the homogeneity of the corresponding spectral lines. A theoretical model is built and a simulation framework has been established to estimate the SBS threshold when input spectra with different homogeneities are set. In our experiment, by setting the phase modulation voltage to a constant value and the modulation frequency to different values, spectral lines with different homogeneities can be obtained. The experimental results show that the SBS threshold increases negatively with the standard deviation of the modulated spectrum, which is in good agreement with the theoretical results. When the phase modulation voltage is confined to 10 V and the modulation frequency is set to 80 MHz, the standard deviation of the modulated spectrum equals 0.0051, which is the lowest value in our experiment. Thus, at this time, the highest SBS threshold has been achieved. This standard deviation can be a good quantitative index in evaluating the power scaling potential in a fiber amplifier system, which is also a design guideline in suppressing the SBS to a better degree.

How to use programme theory to evaluate the effectiveness of schemes designed to improve the work environment in small businesses.

Olsen, Kirsten; Legg, Stephen; Hasle, Peter

2012-01-01

Due to the many constraints that small businesses (SBs) face in meeting legislative requirements, occupational health and safety (OHS) regulatory authorities and other OSH actors have developed programmes which can reach out to SBs and motivate and assist them in improving the work environment. A number of conceptual models help to enhance our understanding of OHS interventions in SBs and their effectiveness. However, they have mainly been evaluated on output rather than the process relating to the change theory underlying the intervention, and hence have seldom been rigorously evaluated. Thus little is known about how particular features of SBs can be taken into account when designing and implementing national programmes. This paper shows how realist analysis and programme theory may be used as a framework for evaluating, developing and improving national intervention programmes for the improvement of the work environment and reducing injuries in SBs. It illustrates this for a specific New Zealand intervention: the Workplace Safety Discount scheme and its implementation in the agriculture sector. In practice, realist analysis should be performed during the planning, implementation and management stages so that ongoing findings can be fed back to the participant social actors to help them make appropriate changes to enhance the likelihood of success.

Although ostomies are sometimes necessary, it is unclear which type of ostomy is advantageous for quality of life (QoL). In an observational study of 2647 patients, QoL after colostomy (CS) and small bowel stoma (SBS) formation was evaluated. The European Organisation for Research and Treatment of Cancer (EORTC)-QLQ-C30 and CR-38 questionnaires were used. Patient characteristics, retrospective information about the ostomy and previous treatments, and current stoma-related complications were recorded. All questionnaires were distributed and collected by stoma therapists at the homecare company PubliCare®. In all, 1790 patients had a CS, and 756 had an SBS. The mean Global Health Score (mGHS-a general QoL indicator) was 52.33 in CS and 49.40 in SBS patients (p = 0.004), but the effect size (Cohen's d) was 0.1. In SBS patients, all functional scores were lower and most of the symptom scores were higher. QoL differed significantly for CS and SBS patients, but the effect size was marginal. The care of certain patient groups, particularly (female) patients who receive emergency surgeries, must be improved. More professional education and guidance are necessary for a larger proportion of patients. This survey provided reference data for quality of life in patients with an ostomy.

Akkoyun, I; Pınarcı, E Y; Yesilirmak, N; Yılmaz, G

2014-10-01

Enhanced depth imaging (EDI) optical coherence tomography (OCT) provides high-definition cross-sectional images of the choroid. Information on alterations in choroidal thickness (CT) after scleral buckling surgery (SBS) is rare. The medical charts of 122 patients (122 eyes) who underwent SBS for macula-off rhegmatogenous retinal detachment (RRD) were retrospectively analyzed. Patients with a follow-up ≥ 6 months were included. Postoperative EDI-OCT images concerning CT were evaluated 1 week, 1 month and 6 months postoperatively in 4 groups: group 1 cerclage + cryopexy (n = 39 eyes), group 2 cerclage + cryopexy + sponge (n = 28 eyes), group 3 SBS + subretinal fluid drainage (SRD) (n = 25 eyes) and group 4 SBS + sponge + SRD (n = 30 eyes). Subfoveal CT was compared between the groups and with the non-operated fellow eye. Subfoveal CT in groups 1, 2, 3 and 4 was thicker 1 week postoperatively. There were no significant differences between the groups or when comparing the operated eye with the fellow eye 1 and 6 months postoperatively. There were no differences in subfoveal CT 1 and 6 months after SBS between the eye with macula-off RRD and the fellow eye. The use of a sponge or SRD induced no differences concerning subfoveal CT.

Testing of methods to enhance the shear bond strength (SBS) between orthodontic metal brackets and amalgam by sandblasting and different primers. Three hundred samples of amalgam restorations (KerrAlloy ® ) were prepared in self-cured acrylic blocks, polished, and divided into two groups: nonsandblasted and sandblasted. Each group was divided into five subgroups with different primers used in surface treatment methods, with a control group of bonded brackets on human mandibular incisors. Following the surface treatments, mandibular incisor brackets (Unitek ® ) were bonded on the amalgam with adhesive resin (Transbond XT ® ). The SBS of the samples was tested. The adhesive remnant index (ARI) and failure modes were then determined under a stereo-microscope. Two-way analysis of variance, Chi-square, and Kruskal-Wallis tests were performed to calculate the correlations between and among the SBS and ARI values, the failure modes, and surface roughness results. There were statistically significant differences of SBS among the different adhesive primers and sandblasting methods ( P 0.05). Using adhesive primers with sandblasting together effectively enhances the SBS between orthodontic metal brackets and amalgam. The two primers with the ingredient methacryloxydecyl dihydrogen phosphate (MDP) monomer, Alloy Primer ® and Assure Plus ® , were the most effective. Including sandblasting in the treatment is essential to achieve the bonding strength required.

To investigate the shear bond strength (SBS) of orthodontic metal brackets applied to different types of ceramic surfaces treated with different etching procedures and bonding agents. Monolithic CAD/CAM ceramic specimens (N = 120; n = 40 each group) of feldspathic ceramic Vita Mark II, resin nanoceramic Lava Ultimate, and hybrid ceramic Vita Enamic were fabricated (14 × 12 × 3 mm). Ceramic specimens were separated into four subgroups (n = 10) according to type of surface treatment and bonding onto the ceramic surface. Within each group, four subgroups were prepared by phosphoric acid, hydrofluoric acid, Transbond XT primer, and Clearfill Ceramic primer. Mandibular central incisor metal brackets were bonded with light-cure composite. The SBS data were analyzed using three-way analysis of variance (ANOVA) and Tukey HSD tests. The highest SBS was found in the Vita Enamic group, which is a hybrid ceramic, etched with hydrofluoric acid and applied Transbond XT Adhesive primer (7.28 ± 2.49 MPa). The lowest SBS was found in the Lava Ultimate group, which is a resin nano-ceramic etched with hydrofluoric acid and applied Clearfill ceramic primer (2.20 ± 1.21 MPa). CAD/CAM material types and bonding procedures affected bond strength ( P .05). The use of Transbond XT as a primer bonding agent resulted in higher SBS.

The propagation and stimulated scattering of intense laser beams interacting with underdense plasmas are two important issues for inertial confinement fusion (ICF). The purpose of this work was to perform experiments under well-controlled interaction conditions and confront them with numerical simulations to test the physics included in the codes. Experimental diagnostics include time and space resolved images of incident and SBS light and of SBS-ion acoustic activity. New numerical diagnostics, including similar constraints as the experimental ones and the treatment of the propagation of the light between the emitting area and the detectors, have been developed. Particular care was put to include realistic plasma density and velocity profiles, as well as laser pulse shape in the simulations. In the experiments presented in this paper, the interaction beam was used with a random phase plate (RPP) to produce a statistical distribution of speckles in the focal volume. Stimulated Brillouin Scattering (SBS) was described using a decomposition of the spatial scales which provides a predictive modeling of SBS in an expanding mm-scale plasma. Spatial and temporal behavior of the SBS-ion acoustic waves was found to be in good agreement with the experimental ones for two laser intensities. (authors)

Social Value Orientation and Capitalism in Societies

Cooperation and competition are core issues in various fields, since they are claimed to affect the evolution of human societies and ecological organizations. A long-standing debate has existed on how social behaviors and preferences are shaped with culture. Considering the economic environment as part of culture, this study examines whether the ongoing modernization of competitive societies, called “capitalism,” affects the evolution of people’s social preferences and behaviors. To test this argument, we implemented field experiments of social value orientation and surveys with 1002 respondents for three different areas of Bangladesh: (i) rural, (ii) transitional and (iii) capitalistic societies. The main result reveals that with the evolution from rural to capitalistic societies, people are likely to be less prosocial and more likely to be competitive. In a transitional society, there is a considerable proportion of “unidentified” people, neither proself nor prosocial, implying the potential existence of unstable states during a transformation period from rural to capitalistic societies. We also find that people become more proself with increasing age, education and number of children. These results suggest that important environmental, climate change or sustainability problems, which require cooperation rather than competition, will pose more danger as societies become capitalistic.

Although titanium presents attractive physical and mechanical properties, there is a need for improving the bond at the titanium/luting cement interface for the longevity of metal ceramic restorations. The purpose of this study was to evaluate the effect of surface treatments on the shear bond strength (SBS) of resin-modified glass ionomer and resin cements to commercially pure titanium (CP Ti). Two hundred and forty CP Ti cast disks (9.0 × 3.0 mm) were divided into 8 surface treatment groups (n=30): 1) 50 µm Al(2)O(3) particles; 2) 120 µm Al(2)O(3) particles; 3) 250 µm Al(2)O(3) particles; 4) 50 µm Al(2)O(3) particles + silane (RelyX Ceramic Primer); 5) 120 µm Al(2)O(3) particles + silane; 6) 250 µm Al(2)O(3) particles + silane; 7) 30 µm silica-modified Al(2)O(3) particles (Cojet Sand) + silane; and 8) 120 µm Al(2)O(3) particles, followed by 110 µm silica-modified Al(2)O(3) particles (Rocatec). The luting cements 1) RelyX Luting 2; 2) RelyX ARC; or 3) RelyX U100 were applied to the treated CP Ti surfaces (n=10). Shear bond strength (SBS) was tested after thermal cycling (5000 cycles, 5°C to 55°C). Data were analyzed by 2-way analysis of variance (ANOVA) and the Tukey HSD post hoc test (α=.05). Failure mode was determined with a stereomicroscope (×20). The surface treatments, cements, and their interaction significantly affected the SBS (Pbehavior for all surface treatments. For both cements, only the group abraded with 50 μm Al(2)O(3) particles had lower SBS than the other groups (P<.05). For RelyX ARC, regardless of silane application, abrasion with 50 μm Al(2)O(3) particles resulted in significantly lower SBS than abrasion with 120 μm and 250 μm particles, which exhibited statistically similar SBS values to each other. Rocatec + silane promoted the highest SBS for RelyX ARC. RelyX U100 presented the highest SBS mean values (P<.001). All groups showed a predominance of adhesive failure mode.

Full Text Available There are four logical possibilities for conceiving the relationship of nature and society: the reduction of society to nature, the projection of nature into society, dualism, and a nature-society-dialectic. This differentiation results in four different approaches. Nature is a self-organizing system that produces an evolutionary hierarchy of interconnected systems with specific qualities. Society is a product of nature where humans produce and reproduce structures that enable and constrain human practices in dynamic processes. Parts of nature are observed and appropriated by humans from within society, these parts are socially constructed and form a subsystem of society. The self-organization cycle of nature and the self-organization cycle of the socio-sphere are mutually connected in a productive cycle of society where natural self-organization serves as the material foundation that enables and constrains social self-organization and human production processes transform natural structures and incorporate these very structures into society as means of production (technologies, raw materials. The economy is that part of the socio-sphere where the relationship between nature and the socio-sphere is established, the mediation is achieved by human labour processes. Nature enters the economic process as material input in the form of means of production (constant capital: machines, raw materials, auxiliary materials. Organized nature that is part of the production process in the form of technology increases the productivity of labour and hence reduces the costs of variable capital (total amount of wages and increases the speed of the production of surplus value. The production system of modern society is oriented on economic profit and productivity, ecological depletion and pollution are by-products of modernization. The Fordist production model that originated in the West and was copied by the Soviet Union is one of the major causes of the global

Full Text Available The Essay considers 'the rule' of the so called post-civil political centre that corresponds to the familiar concept of open society, questioning the good as well as the bad sides of such 'rule'. The research is in the first place about global open society stability and attention is addressed to its present enemies - from terrorism, over organized crime, all the way to the so called local legitimates that are confronting the universal and global legitimates represented by the followers of the open society from the post civil political centre area. The Essay presents the debate with Fukuyama's thesis about the 'end of history' considering that open society, i.e. global post civil political centre has visible enemies who do not allow for dialectics of history to stand still as Fukuyama believed. Instead of Fukuyama's 'end of history' the Essay comes to the conclusion that present global situation is marked by post-modern opposition of liberal-democratic post civil centre and extreme anti civil margins, with reference to the opposition of open society and its enemies, which will put under limits further steps of history towards new socio-historical forms.

Green, Martin S; Guerra, Peter G; Krahn, Andrew D

2011-01-01

The last guidelines on training for adult cardiac electrophysiology (EP) were published by the Canadian Cardiovascular Society in 1996. Since then, substantial changes in the knowledge and practice of EP have mandated a review of the previous guidelines by the Canadian Heart Rhythm Society, an affiliate of the Canadian Cardiovascular Society. Novel tools and techniques also now allow electrophysiologists to map and ablate increasingly complex arrhythmias previously managed with pharmacologic or device therapy. Furthermore, no formal attempt had previously been made to standardize EP training across the country. The 2010 Canadian Cardiovascular Society/Canadian Heart Rhythm Society Training Standards and Maintenance of Competency in Adult Clinical Cardiac Electrophysiology represent a consensus arrived at by panel members from both societies, as well as EP program directors across Canada and other select contributors. In describing program requirements, the technical and cognitive skills that must be acquired to meet training standards, as well as the minimum number of procedures needed in order to acquire these skills, the new guidelines provide EP program directors and committee members with a template to develop an appropriate curriculum for EP training for cardiology fellows here in Canada.

Full Text Available Civil Society envisages the growth of civilization in a way that the society is in “civilized form.” It has been prominent in Social science since time immemorial. Till 18th century, it was synonymous with the state or political society. It was more or less direct translation of Cicero’s Societas’ Civilis and Aristotle’s Koinonia politike. According to Karl Marx, “Civil Society embraces the whole material intercourse of individuals within a definite stage of development of productive forces.” Civil Society is an arena where modern man legitimately gratifies his self-interest and develops his individuality, but also learns the value of group action, social solidarity which educates him for citizenship and equips him to participate in the political sphere of the state. It provides “networks of civic engagement” within which reciprocity is learned and enforced, trust is generated. An active and diverse civil society plays a valuable role in advancement of democracy. It seeks to ensure that citizen’s interests are taken seriously. The social work intervention may not be democratically envisaged until it is promulgated by civic engagement through Civil Society. Methodology: This is a descriptive study which consists of secondary source of data collection based on reports, books, periodic journals, web-based articles. There have been utilized three case studies for reaching the findings of study. This article will highlight on role of civil society in providing democratic space and assisting social workers to ensure inclusive growth through conglomeration of state and individuals.

The interaction of optical and acoustic waves via stimulated Brillouin scattering (SBS) has recently reached on-chip platforms, which has opened new fields of applications ranging from integrated microwave photonics and on-chip narrow-linewidth lasers, to phonon-based optical delay and signal processing schemes. Since SBS is an effect that scales exponentially with interaction length, on-chip implementation on a short length scale is challenging, requiring carefully designed waveguides with optimized opto-acoustic overlap. In this work, we use the principle of Brillouin optical correlation domain analysis to locally measure the SBS spectrum with high spatial resolution of 800 μm and perform a distributed measurement of the Brillouin spectrum along a spiral waveguide in a photonic integrated circuit. This approach gives access to local opto-acoustic properties of the waveguides, including the Brillouin frequency shift and linewidth, essential information for the further development of high quality photonic-phononic waveguides for SBS applications.

Full Text Available We demonstrate a high-speed stimulated Brillouin scattering (SBS spectroscopy system that is able to acquire stimulated Brillouin gain point-spectra in water samples and Intralipid tissue phantoms over 2 GHz within 10 ms and 100 ms, respectively, showing a 10-100 fold increase in acquisition rates over current frequency-domain SBS spectrometers. This improvement was accomplished by integrating an ultra-narrowband hot rubidium-85 vapor notch filter in a simplified frequency-domain SBS spectrometer comprising nearly counter-propagating continuous-wave pump-probe light at 780 nm and conventional single-modulation lock-in detection. The optical notch filter significantly suppressed stray pump light, enabling detection of stimulated Brillouin gain spectra with substantially improved acquisition times at adequate signal-to-noise ratios (∼25 dB in water samples and ∼15 dB in tissue phantoms. These results represent an important step towards the use of SBS spectroscopy for high-speed measurements of Brillouin gain resonances in scattering and non-scattering samples.

A novel red-pigmented, Gram-negative, motile, fluorescent, rod-shaped strain, DZ0503SBS1(T), with a single lateral flagellum, was isolated from the intestine of the nematode Heterorhabditidoides chongmingensis. Comparative 16S rRNA gene sequence analysis indicated that the strain is a member of the genus Serratia, sharing highest sequence similarities with Serratia marcescens subsp. sakuensis JCM 11315(T) (99.8 %), S. marcescens subsp. marcescens DSM 30121(T) (99.5 %) and Serratia ureilytica LMG 22860(T) (98.3 %). Similarities between the rpoB gene sequence of strain DZ0503SBS1(T) and those of S. marcescens subsp. sakuensis JCM 11315(T), S. marcescens subsp. marcescens DSM 30121(T) and S. ureilytica LMG 22860(T) were 98.0, 97.4 and 98.3 %, respectively. DNA-DNA hybridization values of strain DZ0503SBS1(T) with S. marcescens subsp. sakuensis JCM 11315(T), S. marcescens subsp. marcescens DSM 30121(T) and S. ureilytica LMG 22860(T) were 68.2, 65.1 and 53.0 %, respectively. The major isoprenoid quinone of strain DZ0503SBS1(T) was Q-8 and the predominant fatty acids were C(16 : 0) (34.76 %), cyclo-C(17 : 0) (20.03 %) and cyclo-C(19 : 0)omega8c (17.24 %). The cyclo-C(19 : 0)omega8c content (17.24 %) was significantly different from those found in S. marcescens subsp. sakuensis JCM 11315(T) and S. marcescens subsp. marcescens DSM 30121(T). Some characteristics of strain DZ0503SBS1(T), i.e. fluorescence and its symbiotic association with nematodes, have not been reported previously in any species of the genus Serratia. Phenotypic and biochemical characteristics and molecular data show that strain DZ0503SBS1(T) represents a novel species, for which the name Serratia nematodiphila sp. nov. is proposed; the type strain is DZ0503SBS1(T) (=KCTC 22130(T) =CGMCC 1.6853(T)).

The purpose of this work was to analyze surfaces consisting of different restorative materials for shear bond strength (SBS) and failure patterns of metal and ceramic brackets. Bonding involved the use of a universal primer (Monobond® Plus, Ivoclar Vivadent). Six restorative materials were tested, including one composite resin (Clearfil Majesty™ Posterior, Kuraray Noritake Dental), one glass-ceramic material (IPS Empress® Esthetic, Ivoclar Vivadent), one oxide-ceramic material (CORiTEC Zr transpa Disc, imes-icore), two base-metal alloys (remanium® star, Dentaurum; Colado® CC, Ivoclar Vivadent), and one palladium-based alloy (Callisto® 75 Pd, Ivoclar Vivadent). Bovine incisors served as controls. Both metal and ceramic brackets (discovery®/discovery® pearl; Dentaurum) were bonded to the restorative surfaces after sandblasting and pretreatment with Monobond® Plus. A setup modified from DIN 13990-2 was used for SBS testing and adhesive remnant index (ARI)-based analysis of failure patterns. The metal brackets showed the highest mean SBS values on the glass-ceramic material (68.61 N/mm(2)) and the composite resin (67.58 N/mm(2)) and the lowest mean SBS on one of the base-metal alloys (Colado® CC; 14.01 N/mm(2)). The ceramic brackets showed the highest mean SBS on the glass-ceramic material (63.36 N/mm(2)) and the lowest mean SBS on the palladium-based alloy (38.48 N/mm(2)). Significant differences between the metal and ceramic brackets were observed in terms of both SBS values and ARI scores (p bracket types, fractures of the composite-resin and the glass-ceramic samples were observed upon debonding. Opaque restorative materials under metal brackets were found to involve undercuring of the adhesive. Monobond® Plus succeeded in generating high bond strengths of both bracket types on all restorative surfaces. Given our observations of cohesive fracture (including cases of surface avulsion) of the composite-resin and the glass-ceramic samples, we recommend

Material and Methods: One hundred sixty eight rivet-shaped specimens (8.0x2.0 mm were cast and subjected to polishing (P or sandblasting with either 50 mm (50SB or 250 mm (250SB Al2O3. The metal conditioners Metal Photo Primer (MPP, Cesead II Opaque Primer (OP, Targis Link (TL, and one surface modification system Siloc (S, were applied to the specimen surfaces, which were covered with four 1-mm thick layers of resin composite. The resin layers were exposed to curing light for 90 s separately. Seven specimens from each experimental group were stored in water at 37ºC for 24 h while the other 7 specimens were subjected to 5,000 thermal cycles consisting of water baths at 4ºC and 60ºC (n=7. All specimens were subjected to SBS test (0.5 mm/min until failure occurred, and further 28 specimens were analyzed using scanning electron microscope (SEM and X-ray energy-dispersive spectroscopy (EDS. Data were analyzed by 3-way ANOVA followed by post-hoc Tukey's test (α=0.05. Results: On 50SB surfaces, OP groups showed higher SBS means than MPP (P<0.05, while no significant difference was found among OP, S, and TL groups. On 250SB surfaces, OP and TL groups exhibited higher SBS than MPP and S (P<0.05. No significant difference in SBS was found between OP and TL groups nor between MPP and S groups. The use of conditioners on 250SB surfaces resulted in higher SBS means than the use of the same products on 50SB surfaces (P<0.05. Conclusion: Sandblasting associated with the use of metal conditioners improves SBS of resin composites to cpTi.

Civil society has the potential to have a positive impact on social exclusion and health equity through active monitoring and increased accountability. This paper examines the role of civil society in Bangladesh to understand why this potential has not been realized. Looking at two models of civil society action—participation in decentralized public-sector service provision and academic think-tank data analysis—this analysis examines the barriers to positive civil society input into public policy decision-making. The role of non-governmental organizations, political, cultural and economic factors, and the influence of foreign bilateral and multilateral donors are considered. The paper concludes that, with a few exceptions, civil society in Bangladesh replicates the structural inequalities of society at large. PMID:19761087

Full Text Available A common feature of our age is orientation of young people towards transitional values. Economic partnership of consumer society has a direct impact on values of society and even if the process of change of values can be affected by formers of education politics, economists and politicians, young people still choose values, which conform with their own lifestyle. Content of educational subjects is connected with study, succession of cultural values, study of classified knowledge and skills, which is also a prerequisite of formation of personality. Societies of all ages has formed according to the specific mechanism, accumulating and integrating general, notable at that time ideas, preserving and transforming their own social experience to the next generations. Each culture declares itself from its scale of values and norms. Priority of change of post material and material values changes together with conditions of cultural, historical and social-political life. Change of paradigms is change of viewpoint of the world, therefore conditions of value choice relate not only to separate groups, but to whole cultures. Young people, similar to other members of society, are forced to construct their own identity and to form their own life insurance strategies offered by the consumer society. Consumer society forms its values and it is creator of its own significance, but young people as social agents are reproducers of values of consumer society. Research results of World Value Surveys (WVS from six continents discovered big differences in value priorities between younger and older generations, which indicates not only inter-generation value change, but also changes in the whole society. The research “Value choice of young people in consumer society” in our country shows, that although the lifestyle of young people is pragmatic, traditional value – family is also one of the most often mentioned and important values in consumer society.

Founded in 1981, the Japanese Society of Toxicology (JSOT) has grown into an organization of nearly 3,000 members working together to advance the nation's scientific knowledge and understanding of toxicology through the implementation of planning that ensures a systematic and efficient expenditure of energies and resources, and is closely aligned with a strategy for accomplishing the Society's long-range plans. To promote public education in toxicology, the Society organizes public lectures during each year's annual meeting. Other activities include hosting scientific conferences, promoting continuing education, and facilitating international collaboration. Internally, the JSOT operates five standing committees: General Affairs, Educational, Editorial, Finance, and Science and Publicity to handle its necessary relationships. To bestow official recognition, the Society established its Toxicologist Certification Program in 1997, and has certified 536 members as Diplomat Toxicologists (DJSOT) as of May 1, 2016. Furthermore, on the same date, 43 JSOT members were certified as Emeritus Diplomats of the JSOT (EDJSOT). The Society has launched two official journals, the "Journal of Toxicological Sciences (JTS)" in 1981 and "Fundamental Toxicological Sciences (Fundam. Toxicol. Sci.)" in 2014. As for participation in the international organizations, the JSOT (then known as the Toxicological Research Group) joined the International Union of Toxicology as a charter member in 1980, and became a founding member of the Asian Society of Toxicology at its inauguration in 1994. Into the future, the JSOT will continue working diligently to advance knowledge and understanding of toxicology and secure its place among the interdisciplinary fields of science, humane studies, and ethics.

Internal Conflicts in Muslim Societies

Directory of Open Access Journals (Sweden)

Ashiq Ali Shah

2001-12-01

Full Text Available An analysis of psychological theories and the social dynamics of the society help identify salient attributes and processes relevant to conflict among Muslims. The psychodynamic concept of personality and frustration-aggression hypothesis account for the socialization practices in the Muslim societies, emotional instability, unfavorable evaluation of those holding a different viewpoint and venting out one's aggression on the weaker. The tendency of the Muslims to praise their sect/tribe/religious group leads to a groupthink situation that polarizes intergroup relationships. The acts of categorization in group and out group, as postulated by the social identity theory, contribute towards the distorted perception of each other. The Islamic notions of brotherhood, unity and ethnic identity as means of personal identification and social interaction seems to have been forgotten by the Muslims. Though the Western social-psychological constructs are helpful in understanding the causes of conflict among Muslims, they are not germane to Muslim societies. The group belongingness and group favouritism is not necessarily a tool of discrimination and conflict but is an essential component of one's survival in a collectivist society. The Western theories also do not address the economic and political circumstances responsible for the multitude of conflicts among Muslims.

Civil society in a divided society: Linking legitimacy and ethnicness of civil society organizations in Bosnia-Herzegovina.

Puljek-Shank, Randall; Verkoren, Willemijn

2017-06-01

Civil society (CS) strengthening is central to peacebuilding policies for divided, post-war societies. However, it has been criticized for creating internationalized organizations without local backing, unable to represent citizens' interests. Based on in-depth empirical research in Bosnia-Herzegovina, this article focuses on the legitimacy of CS organizations (CSOs). It explores why legitimacy for donors rarely accompanies legitimacy for local actors. We hypothesized that whilst donors avoid supporting mono-ethnic organizations, seen as problematic for peacebuilding, 'ethnicness' may provide local legitimacy. However, our analysis of CSOs' ethnicness nuances research characterizing organizations as either inclusive or divisive. Moreover, local legitimacy is not based on ethnicness per se, but CSOs' ability to skilfully interact with ethnically divided constituencies and political structures. In addition, we offer novel explanations why few organizations enjoy both donor and local legitimacy, including local mistrust of donors' normative frameworks and perceived lack of results. However, we also show that a combination of local and donor legitimacy is possible, and explore this rare but interesting category of organizations.

In the USSR Nuclear Society in 1991 the special working group on the problems of nuclear weapons non-proliferation and nuclear materials control, uniting the experts of different types (nuclear physicists, lawyers, teachers), was created. This group became the mechanism of the practical Nuclear Society activity realization in this sphere. Three milestones of the innovative activity can be specified. First Milestone. In January 1992 the Central Nuclear Society Board (of the International Public Nuclear Society Association) published a special appeal to the First Leaders of all countries - former USSR republics. This address paid a special attention to the unity of the USSR power-industrial complex, and numerous problems arisen while separating this complex, including nuclear weapons non-proliferation problems, were indicated as well. Second Milestone. In 1992 and 1993 the Nuclear Society experts issued two selection 'Nuclear Non-proliferation and Control Problems' including reviewing basic papers. In addition, materials on non-proliferation and control are published regularly in the organs. Third Milestone.In 1993 - 1997 some special scientific and technical events (conferences, workshops, meetings) allowing to analyze the joint international projects and contracts outcomes, and establish new contacts between the specialists of NIS, Baltic states and others, have been hold

2016-07-15

In 2014, the US Food and Drug Administration (FDA) proposed to regulate laboratory-developed tests (LDTs)-diagnostics designed, manufactured, and used within a single laboratory. The Infectious Diseases Society of America, the American Society for Microbiology, and the Pan American Society for Clinical Virology recognize that the FDA is committed to protecting patients. However, our societies are concerned that the proposed regulations will limit access to testing and negatively impact infectious diseases (ID) LDTs. In this joint commentary, our societies discuss why LDTs are critical for ID patient care, hospital infection control, and public health responses. We also highlight how the FDA's proposed regulation of LDTs could impair patient access to life-saving tests and stifle innovation in ID diagnostics. Finally, our societies make specific recommendations for the FDA's consideration to reduce the burden of the proposed new rules on clinical laboratories and protect patients' access to state-of-the art, quality LDTs. © The Author 2016.

Full Text Available Sick building syndrome (SBS is a term used to describe situation in building when more than 30% of occupants suffer from various symptoms which tend to increase by severity during the time people spend in "sick" building and disappear when they leave the building. Typical cases of SBS report vague symptoms, which cannot be objectively measured, and sufferers usually show no clinical signs of illness. Symptom heterogeneity suggests that they do not represent a single disorder. The objective of our study was to establish if SBS is present in our town because new buildings have been built lately producing the artificial environment - exclusively artificial lightning and mechanical ventilation. A total of 812 subjects were included in our study. The investigation of SBS was performed by standardized questionnaires to determine the prevalence of symptoms and complaints. Questionnaires were used to collect data on perception of environment conditions and health during the period they work in this building. The subjects were divided in three groups according to sex, level of education and ownership. Our data suggested that the incidence of symptoms was higher in employers than in owners of the offices. Moreover, the prevalence of SBS was very high - up to 74.76%. It is obvious that certain physical, psychological and organizational factors are involved in the incidence of symptoms, but our investigation suggests that physical factor has a dominant role in development of symptoms, particularly low humidity and low air flow. In addition, our judgment is that SBS exists in our city, probably in the whole country and, therefore, it must be investigated properly.

Full Text Available Sick building syndrome (SBS is a combination of symptoms that can be attributed to exposure to specific building conditions. The present study recruited 389 participants aged 20–65 years from 87 offices of 16 institutions to examine if personal factors, work-related psychosocial stress, and work environments, were associated with five groups of SBS symptoms, including symptoms for eyes, upper respiratory tract, lower respiratory tract, skin, and non-specific systems. Indoor environmental conditions were monitored. Data were analyzed using multivariate logistic regression (MLR analyses and were reported as adjusted Odds Ratios (aOR. SBS symptoms for eyes were associated with older age, sensitivity to tobacco, and low indoor air flow. Upper respiratory symptoms were related to smoking, low social support, longer work days, and dry air. High indoor air flow was associated with reduced upper respiratory symptoms (aOR = 0.29; 95% confidence interval (CI = 0.13–0.67. Lower respiratory symptoms were associated with high work pressure, longer work hours, chemical exposure, migraine, and exposure to new interior painting. Recent interior painting exposure was associated with a high estimated relative risk of low respiratory symptoms (aOR = 20.6; 95% CI = 2.96–143. Smoking, longer work days, low indoor air flow, indoor dryness, and volatile organics exposure, were associated with other non-specified symptoms including headache, tiredness, difficulty concentrating, anger, and dizziness. In conclusion, there are various SBS symptoms associated with different personal characteristics, psychosocial, and environmental factors. Psychosocial factors had stronger relationships with lower respiratory symptoms than with other types of SBS symptoms. Good ventilation could reduce risk factors and may relieve SBS symptoms.

The purpose of this study was to determine the dentin bonding ability of three new universal adhesive systems under different etching modes using fatigue testing. Prime & Bond elect [PE] (DENTSPLY Caulk), Scotchbond Universal [SU] (3M ESPE), and All Bond Universal [AU] (Bisco) were used in this study. A conventional single-step self-etch adhesive, Clearfil Bond SE ONE [CS] (Kuraray Noritake Dental) was also included as a control. Shear bond strengths (SBS) and shear fatigue strength (SFS) to human dentin were obtained in the total-etch mode and self-etch modes. For each test condition, 15 specimens were prepared for the SBS and 30 specimens for SFS. SEM was used to examine representative de-bonded specimens, treated dentin surfaces and the resin/dentin interface for each test condition. Among the universal adhesives, PE in total-etch mode showed significantly higher SBS and SFS values than in self-etch mode. SU and AU did not show any significant difference in SBS and SFS between the total-etch mode and self-etch mode. However, the single-step self-etch adhesive CS showed significantly lower SBS and SFS values in the etch-and-rinse mode when compared to the self-etch mode. Examining the ratio of SFS/SBS, for PE and AU, the etch-and-rinse mode groups showed higher ratios than the self-etch mode groups. The influence of different etching modes on dentin bond quality of universal adhesives was dependent on the adhesive material. However, for the universal adhesives, using the total-etch mode did not have a negative impact on dentin bond quality. Copyright © 2015 Academy of Dental Materials. Published by Elsevier Ltd.

Shaza M. Hammad

Full Text Available ABSTRACT Objective: To evaluate the effect of silica dioxide (SiO2 nanofillers in different bonding systems on shear bond strength (SBS and mode of failure of orthodontic brackets at two experimental times. Methods: Ninety-six intact premolars were divided into four groups: A Conventional acid-etch and primer Transbond XT; B Transbond Plus self-etch primer; and two self-etch bonding systems reinforced with silica dioxide nanofiller at different concentrations: C Futurabond DC at 1%; D Optibond All-in-One at 7%. Each group was allocated into two subgroups (n = 12 according to experimental time (12 and 24 hours. SBS test was performed using a universal testing machine. ARI scores were determined under a stereomicroscope. Scanning electron microscopy (SEM and transmission electron microscopy (TEM were used to determine the size and distribution of nanofillers. One-way ANOVA was used to compare SBS followed by the post-hoc Tukey test. The chi-square test was used to evaluate ARI scores. Results: Mean SBS of Futurabond DC and Optibond All-in-One were significantly lower than conventional system, and there were no significant differences between means SBS obtained with all self-etch bonding systems used in the study. Lower ARI scores were found for Futurabond DC and Optibond All-in-One. There was no significant difference of SBS and ARI obtained at either time points for all bonding systems.

ABSTRACT Objective: To evaluate the effect of silica dioxide (SiO2) nanofillers in different bonding systems on shear bond strength (SBS) and mode of failure of orthodontic brackets at two experimental times. Methods: Ninety-six intact premolars were divided into four groups: A) Conventional acid-etch and primer Transbond XT; B) Transbond Plus self-etch primer; and two self-etch bonding systems reinforced with silica dioxide nanofiller at different concentrations: C) Futurabond DC at 1%; D) Optibond All-in-One at 7%. Each group was allocated into two subgroups (n = 12) according to experimental time (12 and 24 hours). SBS test was performed using a universal testing machine. ARI scores were determined under a stereomicroscope. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to determine the size and distribution of nanofillers. One-way ANOVA was used to compare SBS followed by the post-hoc Tukey test. The chi-square test was used to evaluate ARI scores. Results: Mean SBS of Futurabond DC and Optibond All-in-One were significantly lower than conventional system, and there were no significant differences between means SBS obtained with all self-etch bonding systems used in the study. Lower ARI scores were found for Futurabond DC and Optibond All-in-One. There was no significant difference of SBS and ARI obtained at either time points for all bonding systems. Relative homogeneous distribution of the fillers was observed with the bonding systems. Conclusion: Two nanofilled systems revealed the lowest bond strengths, but still clinically acceptable and less adhesive was left on enamel. It is advisable not to load the brackets immediately to the maximum. PMID:28444018

Previous studies have noticed the high incidence of suboptimal vitamin D (VtD) status and bone loss in short bowel syndrome (SBS) with parenteral nutrition (PN) dependence. However, limited data have focused on adult SBS without PN dependence. Therefore, our objective was to investigate the incidence and risk factors of suboptimal VtD status and bone loss in adult SBS even after weaning off PN. We performed a prospective study of 60 adult patients with SBS. Serum 25-hydroxyvitamin D (25-OHD) was measured by radioimmunoassay. Bone mineral density (BMD) was measured using dual-energy x-ray absorptiometry (DEXA). Medical records and various laboratory parameters were collected in all participants. Suboptimal VtD status was identified in all individuals, including 3 (5.0%) with VtD insufficiency and 57 (95.0%) with VtD deficiency. Residual small bowel length (B, 0.072, P = .001) and duration of SBS (B, -0.066, P = .020) were both significantly correlated with suboptimal VtD levels. Overall, only 2 patients presented a normal BMD; osteopenia and osteoporosis were noted in 41 (68.3%) and 17 (28.3%) individuals, respectively. Low 25-OHD concentration was associated with a decreased BMD (B, 0.065, P = .029). There were no other demographic characteristics or clinical examinations associated with suboptimal VtD levels and bone loss. Suboptimal VtD status and bone loss were common in adult SBS even after weaning off PN. Despite routine oral VtD supplementation, most patients did not achieve satisfactory status. This emphasizes the critical importance of routine surveillance of 25-OHD and BMD, as well as consideration of alternative methods of supplementation after weaning off PN.

On 28-29 March, CERN hosted the fifth edition of the European Physical Society's “Physics and Society” forum. The forum addresses the role of physicists in general society – be they in education, politics, industry or communication. This year, attendees looked at how physicists have adapted - and can continue to adapt - to work in the economic marketplace.   “The forums began back in 2006, as a special closing event for the 2005 World Year of Physics,” explains Martial Ducloy, former President of the French Physical Society and Chair of the EPS Forum Physics and Society. “We decided to keep the sessions going, as they gave physicists a venue to discuss the non-scientific issues that influence their daily work. As the world's largest international physics laboratory – and the venue for this year's EPS Council – CERN seemed the ideal place to host this year's forum.” The forum ...

The judiciary in a free society

2006-04-01

Full Text Available There is increasing debate about the “crisis of the judiciary”, although in modern societies this expression (independent from its concrete content specifically designates the crises of liberal democratic justice, or, it could be said, the crises of the judiciary in liberal and democratic society. Thus, any discussion about the “crisis of the judiciary” appears to demand a contextual framing that helps to clarify the place occupied by the judicial branch in societies such as ours. This article seeks to elucidate this context, from the political and constitutional point of view. The perspective of the History of Political Thinking is considered the most useful, to the degree to which it points to the origin of the intellectual foundation not only of modern judicial power, but of modern society as a whole. In this article, John Locke and Montesquieu are presented as two essential authors because they have made an indelible contribution to this dual structure.

The aim of this study was to test whether a cognitive behavioral and mindfulness-based group sleep intervention would improve sleep and anxiety on school nights in a sample of at-risk adolescents. We also examined whether benefits to sleep and anxiety would be mediated by improvements in sleep hygiene awareness and presleep hyperarousal. Secondary analysis of a randomized controlled trial conducted with 123 adolescent participants (female = 60%; mean age = 14.48) who had high levels of sleep problems and anxiety symptoms. Participants were randomized into a sleep improvement intervention (n = 63) or active control "study skills" intervention (n = 60). Preintervention and postintervention, participants completed the Pittsburgh Sleep Quality Index (PSQI), Spence Children's Anxiety Scale (SCAS), Sleep Beliefs Scale (SBS), and Presleep Hyperarousal Scale (PSAS) and wore an actiwatch and completed a sleep diary for five school nights. The sleep intervention condition was associated with significantly greater improvements in actigraphy-measured sleep onset latency (SOLobj), sleep diary measured sleep efficiency (SEsubj), PSQI, SCAS, SBS, and PSAS, with medium to large effect sizes. Improvements in the PSQI and SCAS were specifically mediated by the measured improvements in the PSAS that resulted from the intervention. Improvements in SOLobj and SEsubj were not specifically related to improvements in any of the putative treatment mechanisms. This study provides evidence that presleep arousal but not sleep hygiene awareness is important for adolescents' perceived sleep quality and could be a target for new treatments of adolescent sleep problems. © Sleep Research Society 2017.

The Soil Science Society of Nigeria (SSSN) founded in 1968, is a registered member of the African Soil Science Association, International Union of Soil Science and the Global Soil Partnership. The Society aims at promoting and fostering better understanding of basic and applied Soil Science in Nigeria. The society also strives to enhance the dissemination of knowledge in all aspects of Soil science and shares ideas with National and International Societies through conferences, symposium, lectures, seminars and journal publications. The numerical strength of the society is 600 members (student, ordinary ,life and corporate). The soil science society of Nigeria has provided invaluable services in the formulation of agricultural land and fertilizer use strategies and policies of the country. The existing reconnaissance soil map of Nigeria typifies one of the major professional services rendered to the country by the society and its members. Despite the numerous contributions the society has made to the advancement of soil science in the country, the larger society is not aware of the its existence. This is largely because of our limited soil extension activities to land users due to lack of funds. If the society can attract donor funds, this will go a long way in enhancing the capacity and capability of the society.

The first congress was during October 1953 and the first president as Maurice Aubry. The first secretary was Daniel Morel Fatio. The symposiums were after about three of four times each year and the thematic subjects were initially according the reconstructive surgery. The review "Annales de chirurgie plastique" was free in 1956. The members of the Society were about 30 initially, but their plastic surgery in the big hospitals at Paris and other big towns in France. The "specialty" of plastic surgery was created in 1971. On "syndicate", one French board of plastic reconstructive and aesthetic surgery, the increasing of departments of plastic surgery were the front of increasing of the plastic surgery in French and of the number of the French Society of Plastic Reconstructive surgery (580 in 2003). The French Society organized the International Congress of Plastic Surgery in 1975. The society SFCPR became the French Society of plastic reconstruction and Aesthetic Surgery (SFCPRE) in 1983 and the "logo" (front view) was in the 1994 SOF.CPRE.

Shaken baby syndrome (SBS) describes the coincidence of subdural hematoma, retinal bleeding and, disadvantageous for the prognosis, diffuse brain damage caused by powerful shaking of the infant. The clinical symptoms include irritability, difficulty with drinking, somnolence, apathy, cerebral cramp attacks, apnoea, temperature regulation disorders and vomiting due to cranial pressure. Milder symptoms of SBS are often not diagnosed and the number of unregistered cases is probably much greater. The diagnosis of SBS is made through the typical symptom constellation, but the lack of retinal bleeding does not exclude the diagnosis. Normally the infants are held by the thorax or upper arms and shaken in a sagittal direction during which the head falls backwards and forwards and is stopped abruptly at each extreme position. The injurious mechanism is considered to be caused by rotational forces which force tissue layers in the brain against each other and also lead to rupture of bridging veins between the skull and the brain. The prognosis is poor and approximately 25% of infants die of SBS within days or weeks. Approximately 75% of survivors suffer from long term damage with physical handicaps, limitations in hearing, visual disturbances up to blindness and mental disorders or combinations of these conditions. Prevention is therefore the most important aspect. (orig.)

Full Text Available Background due to defining the role of people in the development of society and the almost complete absence of scientific management processes capable of progressive development of both individuals and social communities, and nations, and civilization in general. In order to overcome inherent subjectivist methodology of knowledge, psyholohizatorskyh, hiperpolityzovanyh and utilitarian approach, the authors proposed a three-tier system of business processes of society. The conceptual core of the approach consists in the detection task as logical - mathematical laws of subjects of primary, secondary and higher levels of development, and on the mechanisms of their formation and practice. The solution of the tasks allowed the authors to reveal the structure of both the ascending and descending processes of economic society. Thus, the analysis of individual carriers upward changes as «individual», «individuality», «person» and «personality» showed conditionality determination of their activities with «anthropometric», «ethnic», «demographic» and «ideological» mechanisms. Nature as common carriers downstream changes revealed using correlative related «groups», «group «, «groups» and «communities» whose activity is due to «vitalistic», «education», «professional» and «stratification» mechanisms. To disclose the nature and organization of secondary and higher levels of economic society by the authors introduced the category of «citizen», «heneralista», «human space», «human galactic» ‘formation and development is causing «status», «Persona logical», «humanocentric», «institutional», «cluster», «kontaminatsiyni» and other mechanisms. One of the main achievements of the work, the authors consider the possibility of further development and practical implementation of new quality management processes of economic society based multimodal dialectical logic.

Full Text Available Society is the source of immense power. Over the past few centuries humanity has record­ed phenomenal growth in its collective capacity for accomplishment, as reflected in the 12-fold growth in global per capita income since 1800. The remarkable achievements in living standards, longevity, science, technology, industry, education, democracy, human rights, peace and global governance are the result of the exponential development of the capacity of society to harness human energies and convert them into social power for productive purposes. Today, humanity possesses the power and capabilities needed to fully meet the multi-dimensional challenges confronting global society. The source of this energy is people. Human energy is transformed into social power by the increasing reach, frequency and complexity of human relationships. Society is a complex living network of organized relationships between people. Its power issues from channelizing our collective energies in productive ways by means of organizing principles such as coordination, systems, specialization of function, hierarchy of authority, and integration. This immense social power remains largely underutilized. Social science needs to evolve a comprehensive, trans-disciplinary understanding of the roots of social power and the process by which it is generated, distributed and applied. This knowledge is the essential foundation for formulating effective social policies capable of eradicating forever persistent poverty, unemployment and social inequality. This article is based on a series of lectures delivered by the author in the WAAS-WUC course on “Toward a Trans-disciplinary Science of Society” at Dubrovnik on September 1-3, 2014. It traces the development of social power in different fields to show that human and social capital are inexhaustible in potential. The more we harness them, the more they grow.

Network-Based Community Brings forth Sustainable Society

Science.gov (United States)

Kikuchi, Toshiko

It has already been shown that an artificial society based on the three relations of social configuration (market, communal, and obligatory relations) functioning in balance with each other formed a sustainable society which the social reproduction is possible. In this artificial society model, communal relations exist in a network-based community with alternating members rather than a conventional community with cooperative mutual assistance practiced in some agricultural communities. In this paper, using the comparison between network-based communities with alternating members and conventional communities with fixed members, the significance of a network-based community is considered. In concrete terms, the difference in appearance rate for sustainable society, economic activity and asset inequality between network-based communities and conventional communities is analyzed. The appearance rate for a sustainable society of network-based community is higher than that of conventional community. Moreover, most of network-based communities had a larger total number of trade volume than conventional communities. But, the value of Gini coefficient in conventional community is smaller than that of network-based community. These results show that communal relations based on a network-based community is significant for the social reproduction and economic efficiency. However, in such an artificial society, the inequality is sacrificed.

Space and commodity-based society

Gvozden Vladimir

Full Text Available The space is privileged in the commodity-based society. It is well known that the economic space in the 19th and 20th centuries rapidly managed to subordinate all other areas 'conveying and instilling in them their own meanings and goals' (G. Milatović. A new form of space that qualifies commodity society was created, marked by dualities: openness-closeness, private-public, sameness-difference. This paper is an attempt to criticize the usual analysis of the categories of commodity-space, linked to the ambivalent role of the state as a guarantor of the functioning of the commodity-based society, as well as its controlling instance. The increasing delocalisation of the political changes the nature of the space in the commodity-based society. Privileged areas are produced that create an illusion of protection of consumers (shopping malls, gated communities, theme parks, video surveillance, while at the same time social differentiation and identification are produced through the symbolic order of commodities and a sense of inclusion or exclusion from that order. At the same time, the examples of tourism and selling places demonstrate that such a commodity-space unusually easy reconciles sameness and difference. It entails uniformity to help achieve the fluctuation of goods, while insisting on the local as different, especially in terms of the role of particularity in the global trade.

Breno Bernard Nicolau de França

2015-04-01

Full Text Available Despite the possible lack of validity when compared with other science areas, Simulation-Based Studies (SBS in Software Engineering (SE have supported the achievement of some results in the field. However, as it happens with any other sort of experimental study, it is important to identify and deal with threats to validity aiming at increasing their strength and reinforcing results confidence. OBJECTIVE: To identify potential threats to SBS validity in SE and suggest ways to mitigate them. METHOD: To apply qualitative analysis in a dataset resulted from the aggregation of data from a quasi-systematic literature review combined with ad-hoc surveyed information regarding other science areas. RESULTS: The analysis of data extracted from 15 technical papers allowed the identification and classification of 28 different threats to validity concerned with SBS in SE according Cook and Campbell’s categories. Besides, 12 verification and validation procedures applicable to SBS were also analyzed and organized due to their ability to detect these threats to validity. These results were used to make available an improved set of guidelines regarding the planning and reporting of SBS in SE. CONCLUSIONS: Simulation based studies add different threats to validity when compared with traditional studies. They are not well observed and therefore, it is not easy to identify and mitigate all of them without explicit guidance, as the one depicted in this paper.

Full Text Available Objective. The aim of this in vitro study was to determine the shear bond strength (SBS and adhesive remnant index (ARI score of two self-etching no-mix adhesives (iBond™ and Scotchbond™ on different prosthetic surfaces and enamel, in comparison with the commonly used total etch system Transbond XT™. Materials and Methods. A total of 270 surfaces (1 enamel and 8 restorative surfaces, n=30 were randomly divided into three adhesive groups. In group 1 (control brackets were bonded with Transbond XT primer. In the experimental groups iBond adhesive (group 2 and Scotchbond Universal adhesive (group 3 were used. The SBS was measured using a Zwicki 1120™ testing machine. The ARI and SBS were compared statistically using the Kruskal–Wallis test (P≤0.05. Results. Significant differences in SBS and ARI were found between the control group and experimental groups. Conclusions. Transbond XT showed the highest SBS on human enamel. Scotchbond Universal on average provides the best bonding on all other types of surface (metal, composite, and porcelain, with no need for additional primers. It might therefore be helpful for simplifying bonding in orthodontic procedures on restorative materials in patients. If metal brackets have to be bonded to a metal surface, the use of a dual-curing resin is recommended.

The aim of the present study was to determine the influence of different adhesive application methods and etching modes on enamel bond effectiveness of universal adhesives using shear bond strength (SBS) testing and surface free-energy (SFE) measurements. The adhesives Scotchbond Universal, All-Bond Universal, Adhese Universal, and G-Premio Bond were used. Prepared bovine enamel specimens were divided into four groups, based on type of adhesive, and subjected to the following surface treatments: (i) total-etch mode with active application; (ii) total-etch mode with inactive application; (iii) self-etch mode with active application; and (iv) self-etch mode with inactive application. Bonded specimens were subjected to SBS testing. The SFE of the enamel surfaces with adhesive was measured after rinsing with acetone and water. The SBS values in total-etch mode were significantly higher than those in self-etch mode. In total-etch mode, significantly lower SBS values were observed with active application compared with inactive application; in contrast, in self-etch mode there were no significant differences in SBS between active and inactive applications. A reduction in total SFE was observed for active application compared with inactive application. The interaction between etching mode and application method was statistically significant, and the application method significantly affected enamel bond strength in total-etch mode. © 2017 Eur J Oral Sci.

The purpose of this work was to analyze the shear bond strength (SBS) of different adhesives for orthodontic brackets in accordance with DIN 13990-1/-2, also taking into consideration potential effects arising from different scenarios of enamel conditioning and specimen storage. A total of 390 experiments were performed, with groups of 10 specimens subjected to identical treatments. Three adhesives were tested: Transbond™ XT (3M Unitek, Monrovia, USA), Beauty Ortho Bond (Shofu, Kyoto, Japan), and Fuji Ortho LC (GC Europe, Leuven, Belgium). SBS was evaluated separately at the bracket-adhesive and adhesive-enamel interfaces, as well as the total (enamel-adhesive-bracket) interface. The brackets were metal brackets for upper right central incisors (Discovery® from Dentaurum, Ispringen, Germany). A universal testing machine (Zwick Z010, Ulm, Germany) was used for testing the SBS after 15 min, or after storage in distilled water at 37 °C for 24 h, or after 24 h followed by 500 thermocycles alternating between 5 and 55 °C. Transbond™ XT produced the highest levels of SBS. The least favorable performance was observed with Fuji Ortho LC after enamel conditioning with 10 % polyacrylic acid. Thermocycling did not have a significant influence. Transbond™ XT and Beauty Ortho Bond (but not Fuji Ortho LC) yielded levels of SBS adequate for clinical application (≥ 7 MPa).

Objective. The aim of this in vitro study was to determine the shear bond strength (SBS) and adhesive remnant index (ARI) score of two self-etching no-mix adhesives (iBond ™ and Scotchbond ™ ) on different prosthetic surfaces and enamel, in comparison with the commonly used total etch system Transbond XT ™ . Materials and Methods . A total of 270 surfaces (1 enamel and 8 restorative surfaces, n = 30) were randomly divided into three adhesive groups. In group 1 (control) brackets were bonded with Transbond XT primer. In the experimental groups iBond adhesive (group 2) and Scotchbond Universal adhesive (group 3) were used. The SBS was measured using a Zwicki 1120 ™ testing machine. The ARI and SBS were compared statistically using the Kruskal-Wallis test ( P ≤ 0.05). Results . Significant differences in SBS and ARI were found between the control group and experimental groups. Conclusions . Transbond XT showed the highest SBS on human enamel. Scotchbond Universal on average provides the best bonding on all other types of surface (metal, composite, and porcelain), with no need for additional primers. It might therefore be helpful for simplifying bonding in orthodontic procedures on restorative materials in patients. If metal brackets have to be bonded to a metal surface, the use of a dual-curing resin is recommended.

Geoethics and the Role of Professional Geoscience Societies

Science.gov (United States)

Kieffer, S. W.; Palka, J. M.; Geissman, J. W.; Mogk, D. W.

2014-12-01

Codes of Ethics (Conduct) for geoscientists are formulated primarily by professional societies and the codes must be viewed in the context of the Goals (Missions, Values) of the societies. Our survey of the codes of approximately twenty-five societies reveals that most codes enumerate principles centered on practical issues regarding professional conduct of individuals such as plagiarism, fabrication, and falsification, and the obligation of individuals to the profession and society at large. With the exception of statements regarding the ethics of peer review, there is relatively little regarding the ethical obligations of the societies themselves. In essence, the codes call for traditionally honorable behavior of individual members. It is striking, given that the geosciences are largely relevant to the future of Earth, most current codes of societies fail to address our immediate obligations to the environment and Earth itself. We challenge professional organizations to consider the ethical obligations to Earth in both their statements of goals and in their codes of ethics. Actions by societies could enhance the efforts of individual geoscientists to serve society, especially in matters related to hazards, resources and planetary stewardship. Actions we suggest to be considered include: (1) Issue timely position statements on topics in which there is expertise and consensus (some professional societies such as AGU, GSA, AAAS, and the AMS, do this regularly, yet others not at all.); (2) Build databases of case studies regarding geoethics that can be used in university classes; (3) Hold interdisciplinary panel discussions with ethicists, scientists, and policy makers at annual meetings; (4) Foster publication in society journals of contributions relating to ethical questions; and (5) Aggressively pursue the incorporation of geoethical issues in undergraduate and graduate curricula and in continuing professional development.

Towards E-Society Policy Interoperability

Science.gov (United States)

Iannella, Renato

The move towards the Policy-Oriented Web is destined to provide support for policy expression and management in the core web layers. One of the most promising areas that can drive this new technology adoption is e-Society communities. With so much user-generated content being shared by these social networks, there is the real danger that the implicit sharing rules that communities have developed over time will be lost in translation in the new digital communities. This will lead to a corresponding loss in confidence in e-Society sites. The Policy-Oriented Web attempts to turn the implicit into the explicit with a common framework for policy language interoperability and awareness. This paper reports on the policy driving factors from the Social Networks experiences using real-world use cases and scenarios. In particular, the key functions of policy-awareness - for privacy, rights, and identity - will be the driving force that enables the e-Society to appreciate new interoperable policy regimes.

DOES CIVIL SOCIETY CREATE SOCIAL ENTREPRENEURS?

Directory of Open Access Journals (Sweden)

Gauca Oana

2013-07-01

Full Text Available The purpose of this paper is to analyze whether civil society itself can enhance or stimulate the creation of social entrepreneurs, by studying the traits of the civil society and the various definitions attributed to it. The main question that the paper wants to answer to is Does civil society create social entrepreneurs and the main approach used in this research paper is the theoretical one. By studying existing articles and books on the topic, the paper tries to emphasize the various dimensions that civil society can embrace, as pictured by various authors, as well as how these dimensions can relate to social entrepreneurs and the emergence of social businesses. The paper is not meant to be a breakthrough in the field, but rather to launch a question that is related to very important topics these days, social entrepreneurship, social innovation, social businesses and their connection to a very much debated topic-civil society. The paper is work-in progress and wants to stimulate research regarding the search of the sources of social entrepreneurship, in order to analyze them and better establish them as incubators for the future. It wants to be of use to whoever is researching the concepts illustrated above, as well as for those who want to get in touch with the new buzz words of the academic and entrepreneurial fields. The hereby paper stands, as previously stated, in a theoretical framework and the findings represent a mere analysis of the cause-effect relationship between the characteristics of civil society and those of social entrepreneurs. However, we are of the opinion that it can be a very good starting point for the ones interested in the domain, to analyze more sources of social entrepreneurship or further refine the answer to the question addressed in this article.

Some health aspects of high-energy society

International Nuclear Information System (INIS)

Cook, E.

1975-01-01

The intensive use of inanimate energy in industrialized or high-energy society has subsidized research, development, and higher education and has brought about changes in nutrition and life-style that have led to great advances in public health and medicine. The emergence of high-energy society, however, has brought with it a new set of health problems, within which the direct effects of measurable pollution may turn out to be more easily dealt with than some of the indirect and hard-to-calculate consequences of high energy use. High-energy society is critically dependent on energy-intensive transport systems, and these systems in turn are dependent upon a continual supply of petroleum products. In the short-term, the aorta of any industrialized nation is its petroleum-supply network. In the longer run, high-energy society faces the depletion and exhaustion of all the nonrenewable resources on which it has fed. Even if technology provides adequate substitute energy systems, high-energy society may deteriorate socially from inability to cope with affluence

Nuclear energy has a strong relation to a society. However, due to accidents and scandals having occurred in recent years, people's reliability to nuclear energy has significantly swayed and is becoming existence of a worry. Analyzing such a situation and grasping the problem contained are serious problems for people engaging in nuclear field. In order that nuclear energy is properly used in society, communication with general public and in nuclear power plant site area are increasingly getting important as well as grasping the situation and surveying measures for overcoming the problems. On the basis of such an analysis, various activities for betterment of public acceptance of nuclear energy by nuclear industry workers, researchers and the government are proposed. (J.P.N.)

Branding Cities, Changing Societies

DEFF Research Database (Denmark)

Ooi, Can-Seng

Societal changes are seldom discussed in the literature on city branding. The time element is important because it highlights the fluctuating reality of society. The city brand message freezes the place but in fact, the city branding exercise is a continuous process. Society emerges too. City...... brands are supposed to accentuate the uniqueness of the city, be built from the bottom-up and reflect the city's identity. This paper highlights three paradoxes, pointing out that city branding processes can also make cities more alike, bring about societal changes and forge new city identities. A city...... branding campaign does not just present the city, it may change the city. The relationships between the branding exercise and the city are intertwined in the evolution of the place....

How Global is Global Civil Society?

Directory of Open Access Journals (Sweden)

Neera Chandhoke

2015-08-01

Full Text Available In recent times the concept of global civil society has made its appearance on national and international intellectual, as well as political agendas, in a major way. It is of some interest that two other concepts, both of which call for transcendence of national boundaries in precisely the same way as global civil society does, have also made their appearance on the scene of intellectual debates at roughly the same time: the concept of cosmopolitanism and that of transnational justice. All three concepts have dramatically expanded the notion of commitment to one’s fellow beings beyond the nation state. And all three concepts have extended critiques of policies that violate the dignity of human beings from national governments to the practices of inter-national institutions such as the World Bank, the International Monetary Fund, and the World Trade Forum. In sum the inter-related concepts of global civil society, cosmopolitanism, and transnational justice have greatly enlarged the traditional domain of political theory. And yet for any political theorist who is acutely conscious of the phenomenon of power, these concepts are not unproblematic. For the practices of global civil society may just reinforce the intellectual and the moral power of the West over the postcolonial world. This is particularly true of say global human rights organizations. This paper will attempt to raise some questions of the concept and the practices of global civil society from the perspective of the countries of the South.

2000-11-01

The 39-year history of the Teratology Society is reviewed. An abbreviated history is outlined in table form, along with listings of the Warkany Lectures, the postgraduate courses, and officers of the Society. A year-by-year description of the events, including the scientific and social content of the annual meetings and changes in the business of the Society, is given, in many cases using comments from the past presidents. The valuable and unique diversity of the members is discussed and illustrated, presenting the disciplines and main research area of the presidents. The number of submitted abstracts and the various categories are tabulated, averaging the number and type over four periods. Within the past 10 years, a significant increase in the number of abstracts dealing with epidemiology and developmental biology is evident. The Society's development is compared with that of a human, and the question is asked: Have we reached the maturational stage of old age or senescence, or is the Society still maturing gracefully? This question needs further discussion by all the members. During the past 40 years, we have developed the scientific basis to prevent birth defects caused by rubella, alcoholism, and folate deficiency, as well as many other prenatal exposures. We must now engage in the political battles to obtain the resources needed to conduct further research and to implement the prevention programs, as well as to provide care and rehabilitation for persons with birth defects.

Influence of alloy microstructure on the microshear bond strength of basic alloys to a resin luting cement.

Science.gov (United States)

Bauer, José; Costa, José Ferreira; Carvalho, Ceci Nunes; Souza, Douglas Nesadal de; Loguercio, Alessandro Dourado; Grande, Rosa Helena Miranda

2012-01-01

The aim of this study was to evaluate the influence of microstructure and composition of basic alloys on their microshear bond strength (µSBS) to resin luting cement. The alloys used were: Supreme Cast-V (SC), Tilite Star (TS), Wiron 99 (W9), VeraBond II (VBII), VeraBond (VB), Remanium (RM) and IPS d.SIGN 30 (IPS). Five wax patterns (13 mm in diameter and 4mm height) were invested, and cast in a centrifugal casting machine for each basic alloy. The specimens were embedded in resin, polished with a SiC paper and sandblasted. After cleaning the metal surfaces, six tygon tubes (0.5 mm height and 0.75 mm in diameter) were placed on each alloy surface, the resin cement (Panavia F) was inserted, and the excess was removed before light-curing. After storage (24 h/37°C), the specimens were subjected to µSBS testing (0.5 mm/min). The data were subjected to a one-way repeated measures analysis of variance and Turkey's test (α=0.05). After polishing, their microstructures were revealed with specific conditioners. The highest µSBS (mean/standard deviation in MPa) were observed in the alloys with dendritic structure, eutectic formation or precipitation: VB (30.6/1.7), TS (29.8/0.9), SC (30.6/1.7), with the exception of IPS (31.1/0.9) which showed high µSBS but no eutectic formation. The W9 (28.1/1.5), VBII (25.9/2.0) and RM (25.9/0.9) showed the lowest µSBS and no eutectic formation. It seems that alloys with eutectic formation provide the highest µSBS values when bonded to a light-cured resin luting cement.

Associations of indoor carbon dioxide concentrations, VOCS, environmental susceptibilities with mucous membrane and lower respiratory sick building syndrome symptoms in the BASE study: Analyses of the 100 building dataset

Energy Technology Data Exchange (ETDEWEB)

Apte, M.G.; Erdmann, C.A.

2002-10-01

Using the 100 office-building Building Assessment Survey and Evaluation (BASE) Study dataset, we performed multivariate logistic regression analyses to quantify the associations between indoor minus outdoor CO{sub 2} (dCO{sub 2}) concentrations and mucous membrane (MM) and lower respiratory system (Lresp) Sick Building Syndrome (SBS) symptoms, adjusting for age, sex, smoking status, presence of carpet in workspace, thermal exposure, relative humidity, and a marker for entrained automobile exhaust. Using principal components analysis we identified a number of possible sources of 73 measured volatile organic compounds in the office buildings, and assessed the impact of these VOCs on the probability of presenting the SBS symptoms. Additionally we included analysis adjusting for the risks for predisposition of having SBS symptoms associated with the allergic, asthmatic, and environmentally sensitive subpopulations within the office buildings. Adjusted odds ratios (ORs) for statistically significant, dose-dependant associations (p<0.05) for dry eyes, sore throat, nose/sinus congestion, and wheeze symptoms with 100-ppm increases in dCO{sub 2} ranged from 1.1 to 1.2. These results suggest that increases in the ventilation rates per person among typical office buildings will, on average significantly reduce the prevalence of several SBS symptoms, up to 80%, even when these buildings meet the existing ASHRAE ventilation standards for office buildings. VOC sources were observed to play an role in direct association with mucous membrane and lower respiratory irritation, and possibly to be indirectly involved in indoor chemical reactions with ozone that produce irritating compounds associated with SBS symptoms. O-xylene, possibly emitted from furniture coatings was associated with shortness of breath (OR at the maximum concentration = 8, p < 0.05). The environmental sensitivities of a large subset of the office building population add to the overall risk of SBS symptoms (ORs

Evaluating the effect of antioxidant agents on shear bond strength of tooth-colored restorative materials after bleaching: A systematic review.

Science.gov (United States)

Feiz, Atiyeh; Mosleh, Hamid; Nazeri, Rahman

2017-07-01

The main objective of the present study was to make a systematic review of how antioxidant agents affect shear bond strength of tooth-colored restorative materials after bleaching. Electronic search was used to extract the related articles on the targeted key words such as "antioxidant", "dental bleaching" and "shear bond strength" (SBS) from MeSH, PubMed, Medline, and Cochrane electronic data bases. These articles were all published before 2016. Inclusion criteria were restricted to English journal articles concerning humans, clinical trials, cohorts and case-control studies. Therefore, systematic reviews, case reports, letters to editors, editorials and congress abstracts were excluded from the analysis. Most studies conducted on the issue have produced experimental data which are rather controversial, and there is no general agreement about the reported outcomes. As an illustration, most studies have not considered the relationship between the type of antioxidant materials and the shear bond strength. In point of fact, some researchers (e.g Kimyai et al.) have concluded that antioxidants like gel and solution leave similar effects on SBS. Alternatively, certain studies (e.g., Kunt et al.) have produced inconclusive data regarding the impact of one week postponement of the restorative process on SBS after the bleaching process. The results of the studies evaluating the role of various adhesive systems used after bleaching have demonstrated that regardless of the type of adhesive system used, applying antioxidants before restorative procedures can adversely affect the bleaching agents utilized for SBS. It has also been suggested that the type of the adhesive system used might be correlated with the magnitude of SBS. The results obtained from the systematic review of the articles under investigation reflected that the use of antioxidant agents, regardless of their type, form, concentration and duration of application, can improve SBS after bleaching.

Metagenomic analysis indicates Epsilonproteobacteria as a potential cause of microbial corrosion in pipelines injected with bisulfite

Directory of Open Access Journals (Sweden)

2016-01-01

Full Text Available Sodium bisulfite (SBS is used as an oxygen scavenger to decrease corrosion in pipelines transporting brackish subsurface water used in the production of bitumen by steam-assisted gravity drainage. Sequencing 16S rRNA gene amplicons has indicated that SBS addition increased the fraction of the sulfate-reducing bacteria (SRB Desulfomicrobium, as well as of Desulfocapsa, which can also grow by disproportionating sulfite into sulfide, sulfur and sulfate. SRB use cathodic H2, formed by reduction of aqueous protons at the iron surface, or use low potential electrons from iron and aqueous protons directly for sulfate reduction. In order to reveal the effects of SBS treatment in more detail, metagenomic analysis was performed with pipe-associated solids (PAS scraped from a pipe section upstream (PAS-616P and downstream (PAS-821TP of the SBS injection point. A major SBS-induced change in microbial community composition and in affiliated hynL genes for the large subunit of [NiFe] hydrogenase was the appearance of sulfur-metabolizing Epsilonproteobacteria of the genera Sulfuricurvum and Sulfurovum. These are chemolithotrophs, which oxidize sulfide or sulfur with O2 or reduce sulfur with H2. Because O2 was absent, this class likely catalyzed reduction of sulfur (S0 originating from the metabolism of bisulfite with cathodic H2 (or low potential electrons and aqueous protons originating from the corrosion of steel (Fe0. Overall this accelerates reaction of of S0 and Fe0 to form FeS, making this class a potentially powerful contributor to microbial corrosion. The PAS-821TP metagenome also had increased fractions of Deltaproteobacteria including the SRB Desulfomicrobium and Desulfocapsa. Altogether, SBS increased the fraction of hydrogen-utilizing Delta- and Epsilonproteobacteria in brackish-water-transporting pipelines, potentially stimulating anaerobic pipeline corrosion if dosed in excess of the intended oxygen scavenger function.

Full Text Available Objective: The aim of this study is to evaluate the effect of six different prophylactic agents on shear bond strength (SBS of orthodontic brackets. Materials and methods: One hundred twenty-six freshly extracted mandibular bovine incisors were used. Teeth were randomly divided into 7 equal groups (18 per group as follows: group-1 served as control with no pre-treatment; group-2 enamel treated with fluoride varnish (Fluor Protector, Ivoclar Vivadent; group-3 containing casein-phosphopeptide–amorphous calcium-phosphate (CPP–ACP paste (GC Tooth Mousse, RECALDENT™; group-4 with ozone (HealOzone, Kavo; group-5 with glycine powder (Perio Flow, EMS; group-6 with hydroxyapatite powder 99.5% (Coswell S.p.A.; group-7 with a toothpaste made of hydroxyapatite nanocrystals (BioRepair® Plus, Coswell S.p.A. Brackets were all bonded using the same technique with transbond XT (3 M Unitek, Monrovia, CA. All the bonded specimens were stored for 24 h in deionized water (37 °C and subjected to thermal cycling for 1000 cycles. The SBS was measured with an Instron Universal Testing machine and the adhesive remnant was assessed with the adhesive remnant index (ARI using a stereomicroscope at 10× magnification. Results: Statistical differences (ANOVA were found among the seven investigated groups (F = 12.226, p < 0.001. SBS of groups 2, 5 and 6 were significantly lower than the control group (p < 0.05. ARI scores (chi-square test were correlated with the differences of SBS values. Conclusion: CPP–ACP paste, ozone or BioRepair® did not compromise on bracket bond strength. Fluoride, glycine or hydroxyapatite significantly decreased the SBS; only the fluoride group showed significant clinically low (<6 MPa SBS values.

Full Text Available Objectives: This study sought to assess the effect of curcumin nanoparticles (curcNPs on antimicrobial property and shear bond strength (SBS of orthodontic composite to bovine enamel.Materials and Methods: In this in vitro, experimental study, 1%, 5% and 10% curcNPs were added to Transbond XT composite. Stainless steel brackets were bonded to 48 sound bovine incisors in four groups (n=12 using composite containing 0% (control, 1%, 5% and 10% curcNPs. The bracket-tooth SBS was measured by a universal testing machine. The adhesive remnant index (ARI score was calculated after debonding using a stereomicroscope. Also, 180 discs were fabricated of the four composites; 108 were subjected to eluted component test, 36 were used for disc diffusion test and 36 were used for biofilm test to assess their antimicrobial activity against Streptococcus mutans, Streptococcus sanguinis and Lactobacillus acidophilus.Results: The highest and lowest SBS belonged to control and 10% curcNP groups, respectively. The difference in SBS was significant among the four groups (P=0.008. The SBS of control group was significantly higher than that of 10% curcNPs (P=0.006. The four groups were not significantly different in terms of ARI score (P>0.05. Growth inhibition zones were not seen in any group. In biofilm test, the colony counts of all bacteria significantly decreased by an increase in percentage of curcNPs. Colony count significantly decreased only at 30 days.Conclusions: At 1% concentration, curcNPs have significant antimicrobial activity against cariogenic bacteria with no adverse effect on SBS. However, insolubility of curcNPs remains a major drawback.Keywords: Curcumin; Nanoparticles; Shear Strength; Composite Resins; Orthodontic Brackets; Anti-Bacterial Agents

Universal adhesives have been recently introduced for use as self-etch or etch-and-rinse adhesives depending on the dental substrate and clinical condition. However, their bonding effectiveness to laser-irradiated enamel is still not well-known. Thus, the aim of this study was to compare the shear bond strength (SBS) of universal adhesives (Single Bond Universal; Nova Compo-B Plus) applied to Er,Cr:YSGG laser-irradiated enamel with SBS of the same adhesives applied in self-etch and acid-etching modes, respectively. Crown segments of sixty bovine incisors were embedded into standardized acrylic blocks. Flattened enamel surfaces were prepared. Specimens were divided into six groups according to universal adhesives and application modes randomly (n = 10), as follows: Single Bond Universal/acid-etching mode; Nova Compo-B Plus/acid-etching mode; Single Bond Universal/self-etching mode; Nova Compo-B Plus/self-etching mode; and Single Bond Universal/Er,Cr:YSGG Laser-etching mode; Nova Compo-B Plus/Er,Cr:YSGG Laser-etching mode. After surface treatments, universal adhesives were applied onto surfaces. SBS was determined after storage in water for 24 h using a universal testing machine with a crosshead speed of 0.5 mm min -1 . Failure modes were evaluated using a stereomicroscope. Data was analyzed using two-way of analyses of variances (ANOVA) (p = 0.05). Two-way ANOVA revealed that adhesive had no effect on SBS (p = 0.88), but application mode significantly influenced SBS (p = 0.00). Acid-etching significantly increased SBS, whereas there are no significant differences between self-etch mode and laser-etching for both adhesives. The bond strength of universal adhesives may depend on application mode. Acid etching may significantly increase bond strength, while laser etching may provide similar bond strength when compared to self-etch mode. © 2016 Wiley Periodicals, Inc.

Full Text Available Background and aims. Bleaching can considerably reduce shear bond strength (SBS of orthodontic brackets bonded with composite adhesives. Application of antioxidants is a method to reverse the negative effect of bleaching on compositeto-enamel bond. However, the efficacy of antioxidants in increasing the SBS of brackets bonded using resin-modified glassionomer cement (RMGIC has not been studied, which was the aim of this study. Materials and methods. Fifty freshly extracted human maxillary first premolars were bleached with 35% hydrogen peroxide (Pola Office Bleaching, SDI. Sodium ascorbate 10% was applied to the experimental specimens (n=25. All the specimens were etched with 37% phosphoric acid (Ivoclar/Vivadent and bonded using RMGIC (Fuji Ortho LC, GC. The specimens were subjected to incubation (37°C, 24h and thermocycling (1000 cycles, 5-55°C, dwell time = 1 min. The SBS was measured at 0.5 mm/min debonding crosshead speed. The adhesive remnant index (ARI was scored under ×10 magnification. Data were analyzed using Mann-Whitney U test, one- and independent-samples t-test, and Fisher’s exact test (α=0.05. Results. The mean SBS of experimental and control groups were 11.97 ± 4.49 and 7.7 ± 3.19 MPa, respectively. The difference was statistically significant (P=0.000 by t-test. SBS of both control (P=0.014 and experimental (P=0.000 groups were significantly higher than the minimum acceptable SBS of 6 MPa, according to one-sample t-test. Conclusion. Application of ascorbic acid can guarantee a strong bond when RMGIC is to be used. However, RMGIC might tolerate the negative effect of bleaching with minimum SA treatments (or perhaps without treatments, which deserves further studies.

American Cancer Society: the world's wealthiest "nonprofit" institution.

Science.gov (United States)

Epstein, S S

1999-01-01

The American Cancer Society is fixated on damage control--diagnosis and treatment--and basic molecular biology, with indifference or even hostility to cancer prevention. This myopic mindset is compounded by interlocking conflicts of interest with the cancer drug, mammography, and other industries. The "nonprofit" status of the Society is in sharp conflict with its high overhead and expenses, excessive reserves of assets and contributions to political parties. All attempts to reform the Society over the past two decades have failed; a national economic boycott of the Society is long overdue.

1999-01-01

This book brings together the communications presented at the colloquium 'risk and society' held in Paris (France) on November 1998. During this colloquium, the various aspects of risk and of its management were discussed by medical specialists, historians, industrialists, engineers, philosophers, lawyers, politicians and administration representatives. The first theme concerns the controversies generated by the development of some activities (genetics, bio-technologies, nuclear and radiations use). The second theme concerns the management of risks and the way to conciliate the point of view of authorities and citizens (confidence of the public with respect to experts, scientists, industrialists, government and administrative representatives, role played by the media). The debates that took place during the colloquium have shown that the public opinion concerning the nuclear activities or the new technologies greatly depends on the ideological attitudes and on the public's likes and dislikes with respect to some categories of actors (distrust with respect to public decisions, fears with respect to changes and future, nostalgia of the past). The following aspects are reviewed: Notions of risk and hazard (risk and health, risk in today's society, medicine and society, the point of view of the industrialists and of the scientific and technical specialists); from the psychological aspects of the risk to its social aspects (survey of the risk assessment battlefield, social attenuation and amplification of risk, the feeling of risks in Europe, insecurity and delinquency, controversies around radioactivity and health); the negotiation and communication about risks (risk and public health, negotiation around risks, risks and information dissemination about the public debate, communication and crisis, evolution of risk communication, comparison between American and European approaches, the Seveso directive); the public debate and the evolution of risks management (the

Full Text Available Global civil society is the subject of the formation of a new world order and the modern humanitarian outlook, which is based on the primacy of justice and human rights. One of the actors head of global civil society is an international non-governmental organizations. But wrong to equate global civil society with the activities of these organizations only. Mostly they influence governments and their humanitarian and international politics. Meanwhile, the role of global civil and its society various institutions is much greater and significant. The article discusses the various aspects of the civil society from the position that it took place between transnational companies (TNCs and nation-states. The role of the latter is gradually reduced - economic regulation take on multinationals and public administration is a field of activity of various institutions and structures that scientists considered it as a manifestation of global civil society. In Ukraine, which is also involved in the process of globalization, global civil society is one of the main factors of its national civil society.

Superparamagnetic Fe 3 O 4 nanoparticles were first synthesized via soya bean sprouts (SBS) templates under ambient temperature and normal atmosphere. The reaction process was simple, eco-friendly, and convenient to handle. The morphology and crystalline phase of the nanoparticles were determined from scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and X-ray diffraction (XRD) spectra. The effect of SBS template on the formation of Fe 3 O 4 nanoparticles was investigated using X-ray photoemission spectroscopy (XPS) and Fourier-transform infrared spectroscopy (FT-IR). The results indicate that spherical Fe 3 O 4 nanoparticles with an average diameter of 8 nm simultaneously formed on the epidermal surface and the interior stem wall of SBS. The SBS are responsible for size and morphology control during the whole formation of Fe 3 O 4 nanoparticles. In addition, the superconducting quantum interference device (SQUID) results indicate the products are superparamagnetic at room temperature, with blocking temperature (T B ) of 150 K and saturation magnetization of 37.1 emu/g.

Economía política de la Banca de Sombra

Wesley C. Marshall

2016-09-01

Full Text Available Este artículo examina varios elementos de la teoría económica con respecto al dinero y los bancos a través de la historia reciente del sistema bancario de sombra (SBS. Se argumenta que el pánico financiero mundial de 2007- 2009 ha obligado a la economía del mainstream a deshacerse de algunos de sus axiomas con respecto al dinero, la banca y la crisis, aunque manteniendo otros al mismo tiempo. En concreto, las afirmaciones de la doctrina neoliberal que los bancos no pueden crear dinero de la nada y que no pueden crear crisis, han sido rechazadas por miembros prominentes de la comunidad financiera y se han demostrado falsas por el crecimiento y colapso de la SBS. La actual gran crisis puede ser, por tanto, entendida tanto como una crisis de la SBS en su seno operativo, y también de la teoría neoliberal que logró convencer a los reguladores permitir que la SBS existiera.

Full Text Available Lingual orthodontics, among both young and adult patients, increased in popularity during last years. The purposes of the present investigation were to evaluate the shear bond strength (SBS values and Adhesive Remnant Index (ARI scores of different lingual brackets compared with a vestibular control bracket. One hundred bovine teeth were extracted and embedded in resin blocks. Four different lingual brackets (Idea, Leone; STB, Ormco; TTR, RMO; 2D, Forestadent and a vestibular control bracket (Victory, 3M were bonded to the bovine enamel surfaces and subsequently shear tested to failure utilizing a Universal Testing Machine. SBS values were measured. A microscopic evaluation was performed to obtain ARI scores. Statistical analysis was performed at a statistically significant level of p < 0.05 to determine significant differences in SBS values and ARI Scores. No statistically significant variations in SBS were reported among the different groups. Conversely, significant differences were shown in ARI scores among the various groups. Clinical relevance of the present study is that orthodontists can expect similar resistance to debonding forces from lingual appliances as with vestibular brackets.

Investigating the mean dose values as well as dose distributions of the inhabitants in a large number of settlements maybe set down, that the generally calculated mean exposure is a good measure to estimate the collective dose for a settlement or for a large region. Its uncertainty is however too high, and the dose distribution is very broad (250-300%) to estimate the external exposure of any single person. However, models may take into account more details of influencing factors. First of all the surveying of the local contamination density distribution could be more detailed and more accurate. Measure and distribution of the internal exposure (is not the subject of the present work, but it is similarly problematic. In this situation it is very difficult to search the dose-effect relationships exactly, and is also difficult to satisfy the people that their fears are unjustified. Society pays the costs of the nuclear industry and of the possible consequences as well. But society can neither control the nuclear industry nor the possible consequences at all. Both science and single people are waiting for more and detailed information. If we can not decrease the r adiation sensitivity of societies , then the consequences of Chernobyl will be growing unnecessarily, and it can strongly retard the justified development of the nuclear industry as well.

World-wide tendencies and circumstances for nuclear power cannot be said to be moving full of sail with a favorable wind, due to nuclear power plant accidents and comparatively little economical benefit. The present Nuclear Power Plant situation is that some personnel understand a need for the development from the viewpoint of efficient energy usage in the world and environmental problems like global warming. At the same time others oppose future nuclear development from the viewpoint of safety problems and economic cost. These issues may end nuclear development worldwide. Nuclear development must be considered from an international viewpoint and other various aspects. Therefore, all countries concerned should cooperative in the adjustment of research carried out by each country. Nuclear power's future must be efficient in the utilization of limited resources (money, manpower and facilities). It is concluded that the ISRC should only discuss technical matters on nuclear engineering, independent from political influence. Societies agreeing to this idea, provide the ISRC with money and/or manpower and/or facilities. The ISRC will consist of a research program committee and research task forces. Members of the Research Program Committee are the chairmen of the research task forces who are also society representatives. The Committee will discuss research programs and resources. The research task forces will consist of one society representative chairman and specialists on the program

Manchester Astronomical Society celebrated its centenary in September 2003. But that centenary was of a hundred years as the MAS: the history of the society goes back much further, and can be traced directly to that great era of.public awareness of astronomy and amateur interest in Victorian England in the last half of the nineteenth century. Allan Chapman has discussed this period in detail, so the present paper concentrates on the MAS's particular influence on Manchester astronomers and recent work on the history of the society.

2016-10-01

Scientific journals that are owned by a learned society, like the Journal of Neurochemistry (JNC), which is owned by the International Society for Neurochemistry (ISN), benefit the scientific community in that a large proportion of the income is returned to support the scientific mission of the Society. The income generated by the JNC enables the ISN to organize conferences as a platform for members and non-members alike to share their research, supporting researchers particularly in developing countries by travel grants and other funds, and promoting education in student schools. These direct benefits and initiatives for ISN members and non-members distinguish a society journal from pure commerce. However, the world of scholarly publishing is changing rapidly. Open access models have challenged the business model of traditional journal subscription and hence provided free access to publicly funded scientific research. In these models, the manuscript authors pay a publication cost after peer review and acceptance of the manuscript. Over the last decade, numerous new open access journals have been launched and traditional subscription journals have started to offer open access (hybrid journals). However, open access journals follow the general scheme that, of all participating parties, the publisher receives the highest financial benefit. The income is generated by researchers whose positions and research are mostly financed by taxpayers' or funders' money, and by reviewers and editors, who frequently are not reimbursed. Last but not least, the authors pay for the publication of their work after a rigorous and sometimes painful review process. JNC itself has an open access option, at a significantly reduced cost for Society members as an additional benefit. This article provides first-hand insights from two former Editors-in-Chief, Kunihiko Suzuki and Leslie Iversen, about the history of JNC's ownership and about the difficulties and battles fought along the way to

Interaction between stimulated Brillouin scattering and the filamentation instability in plasmas

1992-01-01

The set of equations describing Stimulated Brillouin Scattering (SBS) and the Filamentation Instability (FI) are solved numerically for a spatially periodic system. For short systems (a few wavelengths of the incident light) SBS backscatter modes and the filamentation instability are observed as expected but in addition there are some puzzling features. SBS starts after a significant time delay, is localized, and focuses during its evolution. These features disappear for a long (tens of wavelengths) system for which sidescatter modes are dominant. The energy is dispersed among many non-coherent modes in such a system and none of the modes is strong enough to drive filamentation. The analytic explanation of the ''puzzling features'' is given.

A high power laser propagating through semiconductor plasma undergoes Stimulated Brillouin scattering (SBS) from the electrostrictively generated acoustic perturbations. We have considered that nano-sized grains (NSGs) ions are embedded in semiconductor plasma by means of ion implantation. The NSGs are bombarded by the surrounding plasma particles and collect electrons. By considering a negative charge on the NSGs, we present an analytically study on the effects of NSGs on threshold field for the onset of SBS and Brillouin gain of generated Brillouin scattered mode. It is found that as the charge on the NSGs builds up, the Brillouin gain is significantly raised and the threshold pump field for the onset of SBS process is lowered.

We develop a theoretical model that can be used to predict stimulated Brillouin scattering (SBS) threshold in optical fibers that arises through the effect of Brillouin pump recycling technique. Obtained simulation results from our model are in close agreement with our experimental results. The developed model utilizes single mode optical fiber of different lengths as the Brillouin gain media. For 5-km long single mode fiber, the calculated threshold power for SBS is about 16 mW for conventional technique. This value is reduced to about 8 mW when the residual Brillouin pump is recycled at the end of the fiber. The decrement of SBS threshold is due to longer interaction lengths between Brillouin pump and Stokes wave.

This document is 1 of 2 companion appropriate use criteria (AUC) documents developed by the American College of Cardiology, American Association for Thoracic Surgery, American Heart Association, American Society of Echocardiography, American Society of Nuclear Cardiology, Heart Rhythm Society, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and Society of Thoracic Surgeons. This document addresses the evaluation and use of multimodality imaging in the diagnosis and management of valvular heart disease, whereas the second, companion document addresses this topic with regard to structural heart disease. Although there is clinical overlap, the documents addressing valvular and structural heart disease are published separately, albeit with a common structure. The goal of the companion AUC documents is to provide a comprehensive resource for multimodality imaging in the context of valvular and structural heart disease, encompassing multiple imaging modalities.Using standardized methodology, the clinical scenarios (indications) were developed by a diverse writing group to represent patient presentations encountered in everyday practice and included common applications and anticipated uses. Where appropriate, the scenarios were developed on the basis of the most current American College of Cardiology/American Heart Association guidelines.A separate, independent rating panel scored the 92 clinical scenarios in this document on a scale of 1 to 9. Scores of 7 to 9 indicate that a modality is considered appropriate for the clinical scenario presented. Midrange scores of 4 to 6 indicate that a modality may be appropriate for the clinical scenario, and scores of 1 to 3 indicate that a modality is considered rarely appropriate for the clinical scenario.The primary objective of the AUC is to provide a framework for the assessment of these scenarios by practices that will

The 49-year history of the Teratology Society is reviewed. An abbreviated history is outlined in table form, with listings of the Warkany Lectures, the Continuing Education Courses, and officers of the society. The original article was updated to include the years 2000 to 2010. A year-by-year description of the events is given, including the scientific and social content of the annual meetings and changes in the business of the society, in many cases using comments from the past presidents. The valuable and unique diversity of the members is discussed and illustrated, presenting the disciplines and main research areas of the presidents. The number of submitted abstracts and the various categories are tabulated, averaging the number and type over successive periods. A significant increase in the number of abstracts dealing with epidemiology and developmental biology is evident. The society's development is compared to that of a human, and the question was asked by Shephard et al. (2000): Have we reached the maturational stage of old age or senescence, or is the society still maturing gracefully? This question needs further discussion by all the members. By 2010, many positive changes are happening to revitalize the society. During the past 50 years, we have developed the scientific basis to prevent birth defects caused by rubella, alcoholism, and folate deficiency, as well as other prenatal exposures. We are now taking advantage of advances in many fields to begin shaping the Teratology Society of the 21st century. We must now engage in political battles to obtain the resources needed to conduct further research and to implement prevention programs, as well as to provide care and rehabilitation for persons with birth defects. 2010 Wiley-Liss, Inc.

Thomson, C.; Ting, M.; Orlove, B. S.

2014-12-01

As the first program of its kind, the M.A. in Climate and Society at Columbia University educates students on how climate affects society and vice versa. The 12-month interdisciplinary Master's program is designed to allow students from a wide variety of backgrounds to gain knowledge in climate science and a deep understanding of social sciences and how they related to climate. There are currently more than 250 alumni applying their skills in fields including energy, economics, disaster mitigation, journalism and climate research in more than a dozen countries worldwide. The presentation will highlight three key components of the program that have contributed to its growth and helped alumni become brokers that can effectively put climate science in the hands of the public and policymakers for the benefit of society. Those components include working with other academic departments at Columbia to successfully integrate social science classes into the curriculum; the development of the course Applications in Climate and Society to help students make an overt link between climate and its impacts on society; and providing students with hands-on activities with practitioners in climate-related fields.

Coevolution of nutrigenomics and society: ethical considerations.

Science.gov (United States)

Korthals, Michiel

2011-12-01

To optimize the coevolution of nutrigenomics and society (ie, the reciprocal stimulation of both developments), I analyzed chances for a fruitful match between normative concepts and strategies of both developments. Nutrigenomics embodies ≥ 3 normative concepts. First, food is exclusively interpreted in terms of disease prevention. Second, striving for health is interpreted as the quantification of risks and prevention of diseases through positive food-gene interactions. The third normative idea is that disease prevention by the minimization of risks is an individual's task. My thesis was that these concepts of nutrigenomics would not easily match with concepts of food and health of various food styles in Western societies, which, for instance, parents in the case of metabolic programming endorse and with a philosophical view of the relation between food, health, and the meaning of life. Next, I reflected on the nonsynchronized coevolution of nutrigenomics and society because of this mismatch and introduced the concept of the fair representation of food styles in nutrigenomic developments. To synchronize and optimize the coevolution of nutrigenomics and society, I propose that the research policy of nutrigenomics should change to a research partnership with society on the basis of fair representation.

The Kurdish Resurrection Society (1942-1945

Directory of Open Access Journals (Sweden)

Sohrab Yazdani

2017-12-01

Full Text Available The Kurdish Resurrection Society (known as Komeley Jiyanewey Kurd was the first political society that was founded after August and September 1941 and following the Anglo-Soviet Invasion of Iran. This society arose from traditional and modern strata of urban Kurdish petty bourgeois in Mahabad. The present study aims at discussing the following questions applying a descriptive-analytical approach and using the historical resources and studies: 1. What is the role of the new social and historical structure of the Iranian Kurdistan in forming the Kurdish Resurrection Society? 2. How did the nationalism discourses of the modern absolutist Pahlavi state result in evolving the ideology of Kurdish Resurrection Society (KRS? The evolution of KRS among the traditional and modern strata was the result of the changes and developments occurred in the structure of social forces in Iranian Kurdistan. These changes took place in the aftermath of modernization-related plans of the modern absolutist Pahlavi state in renewing the social structure and cultural assimilation of this era. This policy provoked a new form of collectivism based upon linguistic and ethnic minorities. In other words, while weakening and isolating the forces of the previous order, modernization paved the social and political ways needed for the emergence of new urban Kurdish forces. The Kurdish leaders and elites, affected by the nationalistic discourse of the modern absolutist Pahlavi state, attempted to provide a new definition of their ethnic identity. Thus, the nationalism discourse of the modern absolutist state led to the emergence of a particularistic nationalism discourse of KRS among the Kurds.

Language Contact in Nigerian Multilingual Society

Directory of Open Access Journals (Sweden)

C.A. Adetuyi

2017-12-01

Full Text Available Multilingual society, being a society that has more than one significant lan-guage group is a sociolinguistic phenomenon that arises as a result of language contact but the fundamental problem in this type of society is that to enthrone one of the languages can be accepted conveniently as the National language. Any attempt to enthrone one of the languages at the expense of the other has proven a failure due to the fact that it appears as distinct, which is inherent and regrettably discriminating and domineering on the other languages and this dies in the mine of ethnic bickering. In Nigeria, like many other African nations, multilingualism is a rule, rather than an exemption, the problem of 'forging ahead' is of crucial importance. Among the competing languages that scramble for national recognition or official status, whether indigenous or for-eign, one must emerge as the official language (the language of administration and education at some levels, the language of relevance, from the competition for the purpose of uniting the nation. Fortunately, English has emerged as that privileged language of its kind. The Nigerian society is irretrievably heterogeneous. Students from diverse ethno-linguistic, cultural and economic groups are exposed quite early to several languages, including their mother tongues and English. Nigerian scholars have variously, as have others examined the connection between multilingualism and interference; we avail ourselves of such studies in situating our reflections. This paper thus looks into the importance of language, most especially English language in the multilingual society.

2015-04-01

The founding and early development of the Southern Pediatric Neurology Society was in many ways parallel to that of the Child Neurology Society. The organization started out as the Southern Child Neurology Society but the name was changed at the time of incorporation so as to avoid confusion of identity and purpose with the larger Child Neurology Society. Although there are archives of early days and the later development of the Southern Pediatric Neurology Society, the details have never been set down in a narrative explaining the events that led to the development of the organization. In this paper, we try to produce a written record of the history of the founding and early development of the Southern Pediatric Neurology Society. © The Author(s) 2014.

Influence of Etching Mode on Enamel Bond Durability of Universal Adhesive Systems.

Suzuki, T; Takamizawa, T; Barkmeier, W W; Tsujimoto, A; Endo, H; Erickson, R L; Latta, M A; Miyazaki, M

2016-01-01

The purpose of this study was to determine the enamel bond durability of three universal adhesives in different etching modes through fatigue testing. The three universal adhesives used were Scotchbond Universal, Prime&Bond Elect universal dental adhesive, and All-Bond Universal light-cured dental adhesive. A single-step self-etch adhesive, Clearfil S 3 Bond Plus was used as a control. The shear bond strength (SBS) and shear fatigue strength (SFS) to human enamel were evaluated in total-etch mode and self-etch mode. A stainless steel metal ring with an internal diameter of 2.4 mm was used to bond the resin composite to the flat-ground (4000-grit) tooth surfaces for determination of both SBS and SFS. For each enamel surface treatment, 15 specimens were prepared for SBS and 30 specimens for SFS. The staircase method for fatigue testing was then used to determine the SFS of the resin composite bonded to the enamel using 10-Hz frequencies for 50,000 cycles or until failure occurred. Scanning electron microscopy was used to observe representative debonded specimen surfaces and the resin-enamel interfaces. A two-way analysis of variance and the Tukey post hoc test were used for analysis of the SBS data, whereas a modified t-test with Bonferroni correction was used for the SFS data. All adhesives in total-etch mode showed significantly higher SBS and SFS values than those in self-etch mode. Although All-Bond Universal in self-etch mode showed a significantly lower SBS value than the other adhesives, there was no significant difference in SFS values among the adhesives in this mode. All adhesives showed higher SFS:SBS ratios in total-etch mode than in self-etch mode. With regard to the adhesive systems used in this study, universal adhesives showed higher enamel bond strengths in total-etch mode. Although the influence of different etching modes on the enamel-bonding performance of universal adhesives was found to be dependent on the adhesive material, total-etch mode

Gasco, Jaime; Braun, Jonathan D; McCutcheon, Ian E; Black, Peter M

2011-01-01

To objectively compare the complexity and diversity of the certification process in neurological surgery in member societies of the World Federation of Neurosurgical Societies. This study centers in continental Asia. We provide here an analysis based on the responses provided to a 13-item survey. The data received were analyzed, and three Regional Complexity Scores (RCS) were designed. To compare national board experience, eligibility requirements for access to the certification process, and the obligatory nature of the examinations, an RCS-Organizational score was created (20 points maximum). To analyze the complexity of the examination, an RCS-Components score was designed (20 points maximum). The sum of both is presented in a Global RCS score. Only those countries that responded to the survey and presented nationwide homogeneity in the conduction of neurosurgery examinations could be included within the scoring system. In addition, a descriptive summary of the certification process per responding society is also provided. On the basis of the data provided by our RCS system, the highest global RCS was achieved by South Korea and Malaysia (21/40 points) followed by the joint examination of Singapore and Hong-Kong (FRCS-Ed) (20/40 points), Japan (17/40 points), the Philippines (15/40 points), and Taiwan (13 points). The experience from these leading countries should be of value to all countries within Asia. Copyright © 2011 Elsevier Inc. All rights reserved.

Science and society: the impact of computing at CERN on society

Lecture in English, with simultaneous interpreting into French CERN is often referred to as the place “where the web was born”. The world-wide-web has fundamentally changed society and launched a wave of new global industries. The world-wide-web happened because there was a specific problem that was seen as an Information Technology (IT) challenge by its inventors. As the scientific programme of CERN has progressed, new IT challenges have been faced such as how to handle the mind-boggling amount of data that is produced by the Large Hadron Collider (LHC). Being able to face those challenges has contributed to the success of the LHC and the discovery of the Higgs particle. This public lecture will explore some of those challenges, how they have been tackled and what impact they are having beyond physics and ultimately on society as a whole. ------ Conférence en anglais – traduction simultanée en français On parle souvent du CERN comme le « berceau du web ».

Haseltine, F P; Wentz, A C

1984-09-01

This article reports survey responses from 71 female members of the American Fertility Society during the Society's 1984 annual meeting. Survey questions concern 1) demographic factors such as rank, degree, title, address, and number of children, 2) field of specialization and research interests, and 3) what the Society can do for its meeting participants. The typical respondent is a physician living in the Eastern United States and employed as an assistant professor in an academic setting. In vitro fertilization is the greatest area of interest, followed by general practice, endocrine and male infertility, contraception, and fertility surgery. Survey responses show that women are interested in 1) networking, 2) increased visibility at professional meetings, 3) information about research possibilities and grants, 4) child care provision at Society meetings, and 5) more basic science and physiology oriented presentions in the program. In response to networking interests, the Society will make available information from the surveyed members. Since 16% of respondents have a PH.D., and 77% are employed in academics, the Society should consider more basic presentations. The need for day care indicates changes in Society membership. The Society plans to conduct similar surveys on a regular basis.

The role of risk in society

International Nuclear Information System (INIS)

Whipple, G.H.

The effects on human health caused by production of energy are best understood in terms of mortality. The term risk is used to mean the years of productive life lost as the result of premature death. As a society becomes more energy intensive, the risks to that society from energy production should increase in direct proportion, yet, the advent of the industrial revolution, and subsequent increase in production and use of energy, has resulted in doubled life expectancy at birth. The relation between risk reduction and cost appears to resemble a rectangular hyperbola. Institutionalized efforts at risk reduction may be reaching a point of diminishing returns, whereas individual efforts offer large gains in life expectancy for little effort and expense. A society that strives to reduce all risks will go bankrupt. (J.T.A.)

Stimulated Brillouin scattering reduction induced by self-focusing for a single laser speckle interacting with an expanding plasma

International Nuclear Information System (INIS)

Masson-Laborde, P. E.; Depierreux, S.; Loiseau, P.; Hüller, S.; Pesme, D.; Labaune, Ch.; Bandulet, H.

2014-01-01

The origin of the low level of stimulated Brillouin scattering (SBS) observed in laser-plasma experiments carried out with a single laser speckle is investigated by means of three-dimensional simulations and modeling in the limit when the laser beam power P is well above the critical power for ponderomotive self-focusing We find that the order of magnitude of the time averaged reflectivities, together with the temporal and spatial SBS localization observed in our simulations, are correctly reproduced by our modeling. It is observed that, after a short transient stage, SBS reaches a significant level only (i) as long as the incident laser pulse is increasing in amplitude and (ii) in a single self-focused speckle located in the low-density front part of the plasma. In order to describe self-focusing in an inhomogeneous expanding plasma, we have derived a new Lagrangian density describing this process. Using then a variational approach, our model reproduces the position and the peak intensity of the self-focusing hot spot in the front part of the plasma density profile as well as the local density depletion in this hot spot. The knowledge of these parameters then makes it possible to estimate the spatial amplification of SBS as a function of the laser beam power and consequently to explain the experimentally observed SBS reflectivity, considerably reduced with respect to standard theory in the regime of large laser beam power

Effect of salivary contamination and decontamination on bond strength of two one-step self-etching adhesives to dentin of primary and permanent teeth.

Santschi, Katharina; Peutzfeldt, Anne; Lussi, Adrian; Flury, Simon

2015-02-01

To evaluate the effects of human saliva contamination and two decontamination procedures at different stages of the bonding procedure on the bond strength of two one-step self-etching adhesives to primary and permanent dentin. Extracted human primary and permanent molars (210 of each) were ground to mid-coronal dentin. The dentin specimens were randomly divided into 7 groups (n = 15/group/molar type) for each adhesive (Xeno V+ and Scotchbond Universal): no saliva contamination (control); saliva contamination before or after light curing of the adhesives followed by air drying, rinsing with water spray/air drying, or by rinsing with water spray/air drying/reapplication of the adhesives. Resin composite (Filtek Z250) was applied on the treated dentin surfaces. The specimens were stored at 37°C and 100% humidity for 24 h. After storage, shear bond strength (SBS) was measured and data analyzed with nonparametric ANOVA followed by exact Wilcoxon rank sum tests. Xeno V+ generated significantly higher SBS than Scotchbond Universal when no saliva contamination occurred. Saliva contamination reduced SBS of Xeno V+, with the reduction being more pronounced when contamination occurred before light curing than after. In both situations, decontamination involving reapplication of the adhesive restored SBS. Saliva contamination had no significant effect on Scotchbond Universal. There were no differences in SBS between primary and permanent teeth. Rinsing with water and air drying followed by reapplication of the adhesive restored bond strength to saliva-contaminated dentin.

2013-09-01

Controversy exists on optimal endoscopic management for palliation of malignant hilar obstruction, with advocates for metal "side-by-side" (SBS) and "stent-in-stent" (SIS) techniques. We sought to evaluate the technical feasibility, efficacy, and outcomes of bilateral biliary self-expanding metal stents (SEMS) for treatment of malignant hilar obstruction using a stent with a 6Fr delivery system. This was a single-center, retrospective review of all patients who underwent bilateral placement of Zilver® biliary SEMS for malignant hilar obstruction from January 2010 to August 2012. Patients underwent endoscopic retrograde cholangiopancreatography with placement of stents using either the SIS or SBS stent techniques. Twenty-four patients (19 men, mean age 63 years) underwent bilateral stenting for malignant hilar obstruction during the study period. Seventeen and seven patients underwent the SBS and SIS technique, respectively. Cholangiocarcinoma (n=14) was the most common cause of hilar obstruction. Initial technical success was achieved in 24/24 (100%) of patients; however, 12 (50%) patients required re-intervention during the study period (median 98 days). Comparison of the SBS and SIS groups revealed no statistical difference with respect to need for re-intervention (P=0.31), successful re-intervention (P=0.60), or procedural length (P=0.89). Use of bilateral Zilver® SEMS in either the SBS or SIS configuration is safe, technically feasible, and effective for drainage of malignant hilar obstruction; however, duration of stent patency and procedure-free survival remain variable.

Does the CO2 laser reduce bond strength in different types of ceramic brackets?

Directory of Open Access Journals (Sweden)

Fábio Lourenço Romano

Full Text Available ABSTRACT OBJECTIVE: The aim of this study was to assess in vitro the influence of the CO2 laser and of the type of ceramic bracket on the shear bond strength (SBS to enamel. METHODS: A total of 60 enamel test surfaces were obtained from bovine incisors and randomly assigned to two groups, according to the ceramic bracket used: Allure (A; Transcend (T. Each group was divided into 2 subgroups (n = 15: L, laser (10W, 3s; C, no laser, or control. Twenty-four hours after the bonding protocol using Transbond XT, SBS was tested at a crosshead speed of 0.5 mm/min in a universal testing machine. After debonding, the Adhesive Remnant Index (ARI was evaluated at 10 x magnification and compared among the groups. Data were analyzed by one-way ANOVA, Tukey’s, Mann-Whitney’s and Kruskal-Wallis tests (α = 0.05. RESULTS: Mean SBS in MPa were: AL = 0.88 ± 0.84; AC = 12.22 ± 3.45; TL = 12.10 ± 5.11; TC = 17.71 ± 6.16. ARI analysis showed that 73% of the specimens presented the entire adhesive remaining on the tooth surfaces (score 3. TC group presented significantly higher SBS than the other groups. The lased specimens showed significantly lower bond strength than the non-lased groups for both tested brackets. CONCLUSION: CO2 laser irradiation decreased SBS values of the polycrystalline ceramic brackets, mainly Allure.

Effects of delayed polymerization time and bracket manipulation on orthodontic resin modified glass ionomer adhesive

Science.gov (United States)

Gilbert, Danielle Wiggins

This study examined the effect of varying delayed polymerization times in combination with bracket manipulation on shear bond strength (SBS), degree of conversion (DC), and adhesive remnant index (ARI) score when using a resin modified glass ionomer (RMGI) adhesive. Specimens were divided into three groups of clinically relevant delay times (0.5, 2, and 4-min) to simulate the delay that frequently occurs between bracket placement and manipulation and subsequent light curing. Based on an analysis of variance (alpha=.05), the SBS was not significantly different between the three groups. While one of the goals of this study was to be the first study to quantify DC of RMGI using Raman microspectroscopy, several challenges, including weak peak signal with and without fluorescence, were encountered and as a result, DC could not be determined. A significant difference (pbracket with increasing delay time. A Spearman correlation between SBS and ARI indicated no positive association between SBS and ARI measures across delay times. The results of this study suggest that clinically relevant delay times of 0.5, 2, and 4-min do not negatively impact the SBS of a RMGI adhesive. However, with increasing delay time, the results suggest that more adhesive might remain on the bracket during debonding. With more adhesive remaining on the bracket, this could be beneficial in that less adhesive needs to be removed from enamel by grinding at the time of bracket removal when orthodontic treatment is completed.

The influence of an oxygen-inhibited layer (OIL) on the shear bond strength (SBS) to enamel and surface free-energy (SFE) of adhesive systems was investigated. The adhesive systems tested were Scotchbond Multipurpose (SM), Clearfil SE Bond (CS), and Scotchbond Universal (SU). Resin composite was bonded to bovine enamel surfaces to determine the SBS, with and without an OIL, of adhesives. The SFE of cured adhesives with and without an OIL were determined by measuring the contact angles of three test liquids. There were no significant differences in the mean SBS of SM and CS specimens with or without an OIL; however, the mean SBS of SU specimens with an OIL was significantly higher than that of SU specimens without an OIL. For all three systems, the mean total SFE (γS), polarity force (γSp), and hydrogen bonding force (γSh) values of cured adhesives with an OIL were significantly higher than those of cured adhesives without an OIL. The results of this study indicate that the presence of an OIL promotes higher SBS of a single-step self-etch adhesive system, but not of a three-step or a two-step self-etch primer system. The SFE values of cured adhesives with an OIL were significantly higher than those without an OIL. The SFE characteristics of the OIL of adhesives differed depending on the type of adhesive. © 2015 Eur J Oral Sci.

Full Text Available Introduction: This study aimed to evaluate the effect of pretreatment with a neutral fluoride agent on shear bond strength (SBS and microleakage of orthodontic brackets, and to investigate any significant relationship between SBS and microleakage. Methods: Forty intact premolars were selected and randomly divided into 2 groups. Group 1 served as the control, while group 2 underwent treatment with a 2% sodium fluoride (NaF gel, which was applied on the enamel surface for 4 minutes before etching. After bonding orthodontic brackets, the teeth were immersed for 12 hours in methylen blue dye, followed by mounting in acrylic resin. Shear bond strength was determined using an Instron Universal Testing Machine and the amount of microleakage and the adhesive remnant index (ARI were assessed under a stereomicroscope. Results: The mean SBS and microleakage beneath metal brackets were not significantly different among the control and NaF-treated groups (P>0.05. Furthermore, no significant correlation was found between SBS and microleakage (r=-0.04, P=0.796. The ARI scores revealed that in both groups, most of the adhesive remained on the enamel surface after debonding. Conclusions: It may be concluded that pretreatment of enamel with 2% NaF prior to the bonding procedure does not significantly affect microleakage and SBS of orthodontic brackets and thus, it can be recommended as a suitable approach to reduce the incidence of white spot lesions in orthodontically treated patients, especially those at high risk of caries formation.

2015-12-01

Full Text Available Contemporary society is moving in the core of a reality in which sustainability needs to be thought out and inserted through practices carried out in different dimensions of society, such as organizations, public and private institutions. This paper aims to identify the contribution of innovation habitats (IH for sustainability in society. The methodology used was systematic review of scientific literature in one online database. As a result, it was identified: 47 scientific papers publicated since 2000, but more frequently in the last year, 2014, with 10 publications, without providing a reference author in the area. There was also a high number of papers about management and social sciences. It was noticed a short number of publications, empirical and theoretical, about practices to promote sustainable actions in the society, so this indicates the need of research on this kind of practices, with innovation environment as the driver.

Support Science by Publishing in Scientific Society Journals.

Scientific societies provide numerous services to the scientific enterprise, including convening meetings, publishing journals, developing scientific programs, advocating for science, promoting education, providing cohesion and direction for the discipline, and more. For most scientific societies, publishing provides revenues that support these important activities. In recent decades, the proportion of papers on microbiology published in scientific society journals has declined. This is largely due to two competing pressures: authors' drive to publish in "glam journals"-those with high journal impact factors-and the availability of "mega journals," which offer speedy publication of articles regardless of their potential impact. The decline in submissions to scientific society journals and the lack of enthusiasm on the part of many scientists to publish in them should be matters of serious concern to all scientists because they impact the service that scientific societies can provide to their members and to science.

Who's making global civil society: philanthropy and US empire in world society.

Science.gov (United States)

Vogel, Ann

2006-12-01

Theories of US hegemony commonly ignore the role of American philanthropy in the contemporary transformations of world society and the globalization of capitalism. In this essay, I suggest that the philanthropic foundation, and with it the institution of philanthropy, is being invigorated by the expansion of its domestic role to foreign activities and to globally framed activities within the USA. I propose that US philanthropy exports American understandings of democracy and simultaneously organizes global reflexivity through citizenship education for the US populace. I offer a preliminary theoretical interpretation of the empirical patterns of international grant-making activities by US foundations, considering John W. Meyer's concept of 'instrumental culture' and some arguments made by Foucauldian 'governmentality' scholars. I emphasize the need to conceptualize the cultural-symbolic and organizational dimensions of hegemony and suggest further sociological analysis of philanthropic activities as integral to current politically and economically led transformations of societies around the globe.

Refractory angina (RFA) is a debilitating disease characterized by cardiac pain resistant to conventional treatments for coronary artery disease including nitrates, calcium-channel and β-adrenoceptor blockade, vasculoprotective agents, percutaneous coronary interventions, and coronary artery bypass grafting. The mortality rate of patients living with RFA is not known but is thought to be in the range of approximately 3%. These individuals suffer severely impaired health-related quality of life with recurrent and sustained pain, poor general health status, psychological distress, impaired role functioning, and activity restriction. Effective care for RFA sufferers in Canada is critically underdeveloped. These guidelines are predicated upon a 2009 Canadian Cardiovascular Society (CCS) Position Statement which identified that underlying the problem of RFA management is the lack of a formalized, coordinated, interprofessional strategy between the cardiovascular and pain science/clinical communities. The guidelines are therefore a joint initiative of the CCS and the Canadian Pain Society (CPS) and make practice recommendations about treatment options for RFA that are based on the best available evidence. Concluding summary recommendations are also made, giving direction to future clinical practice and research on RFA management in Canada. Copyright © 2012 Canadian Cardiovascular Society.

The open society and its enemies

CERN Document Server

Popper, Karl Raimund

2003-01-01

Written in political exile during the Second World War and first published in 1945, Karl Popper's The Open Society and Its Enemies is one of the most influential books of the twentieth century. Hailed by Bertrand Russell as a 'vigorous and profound defence of democracy', its now legendary attack on the philosophies of Plato, Hegel and Marx exposed the dangers inherent in centrally planned political systems. Popper's highly accessible style, his erudite and lucid explanations of the thought of great philosophers and the recent resurgence of totalitarian regimes around the world are just three of the reasons for the enduring popularity of The Open Society and Its Enemies, and for why it demands to be read both today and in years to come. This is the second of two volumes of The Open Society and Its Enemies.

2012-01-01

The Fifth Physics and Society Forum, organized by the European Physical Society, will take place at CERN from 28 to 29 March 2012. 
The purpose of the meeting is to explore the challenges experienced by physicists who leave their field of study to pursue alternative careers in the market place outside of teaching and university-based research. 
     It is widely recognized that a knowledgeable society is a prerequisite for growth. Value is only created if knowledge can be transformed into know-how and "know-how-to-do". Today it is widely recognized that a society is unable to grow and sustain an advanced science system unless equally advanced production is present. Today production is off-shored to emerging economies in Asia and elsewhere where labour costs are more favourable. European physicists therefore have the choice of being smarter, working harder and working cheaper or moving into other fields.

2018-02-01

Despite more than a half century of "safe" cardiopulmonary bypass (CPB), the evidence base surrounding the conduct of anticoagulation therapy for CPB has not been organized into a succinct guideline. For this and other reasons, there is enormous practice variability relating to the use and dosing of heparin, monitoring heparin anticoagulation, reversal of anticoagulation, and the use of alternative anticoagulants. To address this and other gaps, The Society of Thoracic Surgeons, the Society of Cardiovascular Anesthesiologists, and the American Society of Extracorporeal Technology developed an Evidence Based Workgroup. This was a group of interdisciplinary professionals gathered to summarize the evidence and create practice recommendations for various aspects of CPB. To date, anticoagulation practices in CPB have not been standardized in accordance with the evidence base. This clinical practice guideline was written with the intent to fill the evidence gap and to establish best practices in anticoagulation therapy for CPB using the available evidence. To identify relevant evidence, a systematic review was outlined and literature searches were conducted in PubMed using standardized medical subject heading (MeSH) terms from the National Library of Medicine list of search terms. Search dates were inclusive of January 2000 to December 2015. The search yielded 833 abstracts, which were reviewed by two independent reviewers. Once accepted into the full manuscript review stage, two members of the writing group evaluated each of 286 full papers for inclusion eligibility into the guideline document. Ninety-six manuscripts were included in the final review. In addition, 17 manuscripts published before 2000 were included to provide method, context, or additional supporting evidence for the recommendations as these papers were considered sentinel publications. Members of the writing group wrote and developed recommendations based on review of the articles obtained and achieved

The structural qualities of modern societies of this day occur in this era. The political and economic changes and transformations that England experienced in this period of time are in enormous scale. In this period all social structure and institutions experienced structural change in terms of cultural, economic and political processes. In addition to this in this period the framework of the international system regarding economy and politics is established too. Important qualities of current modern societies are the speed of communication and interaction between its elements, its transformational capacity and the extent of its scope.

The Good Society: Lessons for Integrated Governance

Directory of Open Access Journals (Sweden)

Neesham C.

2009-12-01

Full Text Available In this paper I argue that philosophies of the good society can inform theories of integrated governance in two significant ways. Firstly, they can provide a reasonable foundation for legitimating forms of authority to govern a society across the government, corporate and civil sector. Secondly, they promote value systems that can be constitutive of a normative theory of integrated governance. In developing this argument, I explore conceptions of the good society put forward by Marquis de Condorcet, Adam Smith and Karl Marx, and evaluate the modalities in which the social projects proposed by these authors involve issues of integrated governance. For this purpose, I examine the three theories in relation to three questions: (1 What goals (or objectives should social action be directed to? (2 What should be the scope and limits of social responsibility lying behind the social authority of each sector (government, market or civil society? (3 How is social authority to be exercised beyond legislation? What source(s of legitimacy should one appeal to? Although Condorcet’s idea of the natural social order, Smith’s system of natural liberty and Marx’s political economy of human value have all received their fair share of criticism from empirical theories of society, I suggest that these conceptions are still useful to us today as radical normative experiments. These experiments can have guiding value in formulating models of integrated governance. However, the fundamental differences displayed by these three conceptions reveal the importance of determining whether one can develop models of integrated governance that would accommodate plural, incompatible, or unknown conceptions of the good society.

Northern Peru has an exceptionally rich archaeological heritage that includes metalwork, ceramics and textiles. The success of at least a half-dozen pre-Columbian societies dating back 3,000 years and subsequent Spanish colonization in the 1400s has rested on the effective use of northern Peru's abundant resources. In the summer of 2000, my son Matt and I learned about that connection firsthand by volunteering at the Santa Rita B archaeological site in the Chao Valley near Trujillo in northern Peru. Riding donkey-back through the Andes and talking with local people, we got our hands dirty in the rich archaeology and geology of the area. We were able to correlate mineral occurrences to their various roles in society - opening a window into the region's fascinating past. From construction to metallurgy, pre-Columbian societies flourished and advanced because of their understanding and use of the available mineral resources.

American Nuclear Society exchanges of information

Du Temple, O.J.

2000-01-01

Many are familiar with the technical journals and other publications that American Nuclear Society (ANS) members receive. However, there is a whole series of documents that is helpful to any nuclear society group for a modest fee or no fee. The author is referring to documents such as the ANS Bylaws and Rules, which have been made available to almost every existing nuclear society in the world. He remembers working with groups from Russia, Europe, China, Japan, Brazil, France, Germany, and others when they sought the experience of ANS in establishing a society. Financial planning guides are available for meetings, international conferences, technical expositions, and teacher workshops. Periodically, the ANS publishes position papers on the uses and handling of fuel materials and other publications helpful to public relations and teacher training courses. A few have had distributions in the hundreds of thousands, and one went as high as 750,000. Some of these have been translated in part into Spanish, French, Portuguese, and Japanese. Nuclear Standards are developed by a series of ANS committees consisting of about 1000 experts--the largest technical operation of ANS. Buyers guides and directories are very helpful in promoting the commerce in the nuclear industry. The Utility Directory covers utilities all over the globe. Radwaste Solutions, the new name for the former Radwaste Magazine, covers the efforts made by all sectors--private, government, and utility--to deal with radioactive waste. In the author's opinion, the one area in which all societies are weak is in interfacing with the International Atomic Energy Agency (IAEA). Since his retirement 9 yr ago, he has become much more aware of the IAEA as a news and technical information source. The ANS is trying to be more aware of what the IAEA is doing for everyone
