The starch extracted from avocado (Persea americana L. cv. Hass) seeds was characterized and used in the preparation of an edible coating to reduce the oil uptake and acrylamide content in French fries. Starch characterization was carried out using Differential Scanning Calorimetry, Fourier transform infrared spectrophotometry, gelatinization, and scanning electron microscopy. Uncoated (UFF) and coated (CFF) French fries were compared and evaluated for moisture, water activity (Aw), fat, color, firmness, acrylamide content, and sensorial analysis. The extracted starch presented a high crystalline structure and good stability to mechanical work and heat treatments. The CFF French fries showed significantly higher Aw, color parameter a*, but lower luminosity and acrylamide content than UFF samples. Similarly, the CFF samples tended to decrease the fat content, although without statistical differences. Avocado seed starch can be an economical and technically feasible alternative to the food industry as an effective coating to reduce acrylamide content in French fries.

회복이론(recovery theory)의 적용

Robert Bland,Ann Tullgren 한국정신건강사회복지학회 2013 한국정신건강사회복지학회 학술발표논문집 Vol.2013 No.5

20년 전부터 동장한 회복(recovery) 개념은 정신질환을 어떻게 이해할 것인지 또 정신질환을 가진 사람들을 돕기 위해 어떻게 서비스를 제공할 것인지에 관해 구체화 한 주요 이론적 원리이다. 회복은 정신질환이 없이 또는 정신질환이 있음에도 잘 사는 것(living)으로 간단히 정의된다. 여기에서는 개인적인 삶의 질(wellbeing)이 증세를 치료하는 것보다 더 중요하다. 즉, 치유가 치료보다 더 중요하다는 것이다. 질병과 치료의 생활 경험(lived experience)을 강조하는 것이 회복의 주축을 이룬다. 본고에서는 회복의 차원을 희망과 헌신을 새롭게 하기, 자아를 재규정하기, 질병을 구체화하기, 의미 있는 활동에 참여하기, 낙인을 극복하기, 통제권을 갖기, 역량강화 되기, 증세를 관리하기, 다른 사람들의 지지를 받기 등으로 기술한다. 결론에서는 회복 실천의 여러 주요 원리들을 제시한다. 여기에는 돌봄을 개별화하기, 관계의 중요성을 존중하기, 회복 사정, 희망을 유지하기, 현실적인 시간 관점을 채책하기, 전체적인(holistic) 접근방식을 채택하기, 강점 관점을 적용하기가 포함된다. 회복 이론은 정신건강 분야의 사회복지실천을 위한 종합적인 모델을 제공하는가? Over the last twenty years the concept of recovery has emerged as a central theoretical principle shaping the way we understand mental illness, and how services are provided to help people with mental illness. Recovery is simply defined as living well in the presence or absence of mental illness. Personal wellbeing is more important than treating symptoms; healing is more important than cure. Central to recovery is an emphasis on the lived experience of illness and treatment. This paper describes the dimensions of recovery as renewing hope and commitment, redefining self, incorporating illness, becoming involved in meaningful activities, overcoming stigma, assuming control, becoming empowered, managing symptoms, and being supported by others. Finally we suggest a number of key principles for recovery practice. These are individualizing care, respecting the centrality of relationship, recovery assessment, sustaining hopefulness, adopting a realistic time perspective, adopting an holistic approach, and applying a strengths perspective. Does recovery theory offer a comprehensive model for social work practice in the mental health field?

Effects of liposomal-curcumin on five opportunistic bacterial strains found in the equine hindgut - preliminary study

( S. D. Bland ),( E. B. Venable ),( J. L. Mcpherson ),( R. L. Atkinson ) 한국축산학회 2017 한국축산학회지 Vol.59 No.6

Background: The horse intestinal tract is sensitive and contains a highly complex microbial population. A shift in the microbial population can lead to various issues such as inflammation and colic. The use of nutraceuticals in the equine industry is on the rise and curcumin is thought to possess antimicrobial properties that may help to minimize the proliferation of opportunistic bacteria. Methods: Four cecally-cannulated horses were utilized to determine the optimal dose of liposomal-curcumin (LIPC) on reducing Streptococcus bovis/equinus complex (SBEC), Escherichia coli K-12, Escherichia coli general, Clostridium difficile, and Clostridium perfringens in the equine hindgut without adversely affecting cecal characteristics. In the first study cecal fluid was collected from each horse and composited for an in vitro, 24 h batch culture to examine LIPC at four different dosages (15, 20, 25, and 30 g) in a completely randomized design. A subsequent in vivo 4 × 4 Latin square design study was conducted to evaluate no LIPC (control, CON) or LIPC dosed at 15, 25, and 35 g per day (dosages determined from in vitro results) for 9 days on the efficacy of LIPC on selected bacterial strains, pH, and volatile fatty acids. Each period was 14 days with 9 d for acclimation and 5 d withdrawal period. Results: In the in vitro study dosage had no effect (P ≥ 0.42) on Clostridium strains, but as the dose increased SBEC concentrations increased (P = 0.001). Concentrations of the E. coli strain varied with dose. In vivo, LIPC`s antimicrobial properties, at 15 g, significantly decreased (P = 0.02) SBEC when compared to 25 and 35 g dosages. C. perfringens decreased linearly (P = 0.03) as LIPC dose increased. Butyrate decreased linearly (P = 0.01) as LIPC dose increased. Conclusion: Further studies should be conducted with a longer dosing period to examine the antimicrobial properties of curcumin without adversely affecting cecal characteristics.

Recent advances in spin-polarized electron transport at the ferromagnet/semiconductor interface are summarized in the contextbased on recent studies of polarized luminescence in ferromagnet/quantum well light emitting diode structures. Our recent results onspin-polarized electron transport from GaAs into Fe under optical spin pumping are shown. These observations clearly indicate animportance of the introduction of a tunneling barrier between the ferromagnetic metal and semiconductor in order to achieve a highspin injection and detection eciency.. 2003 Published by Elsevier B.V.

THE SAMI GALAXY SURVEY: REVISITING GALAXY CLASSIFICATION THROUGH HIGH-ORDER STELLAR KINEMATICS

Sande, Jesse van de,Bland-Hawthorn, Joss,Fogarty, Lisa M. R.,Cortese, Luca,d’Eugenio, Francesco,Croom, Scott M.,Scott, Nicholas,Allen, James T.,Brough, Sarah,Bryant, Julia J.,Cecil, Gerald,Colless, Ma American Astronomical Society 2017 The Astrophysical journal Vol.835 No.1

<P>Recent cosmological hydrodynamical simulations suggest that integral field spectroscopy can connect the high-order stellar kinematic moments h(3) (similar to skewness) and h(4) (similar to kurtosis) in galaxies to their cosmological assembly history. Here, we assess these results by measuring the stellar kinematics on a sample of 315 galaxies, without a morphological selection, using two-dimensional integral field data from the SAMI Galaxy Survey. Proxies for the spin parameter (lambda(Re)) and ellipticity (epsilon(e)) are used to separate fast and slow rotators; there exists a good correspondence to regular and non-regular rotators, respectively, as also seen in earlier studies. We confirm that regular rotators show a strong h(3) versus V/sigma s anti-correlation, whereas quasi-regular and non-regular rotators show a more vertical relation in h(3) and V/sigma. Motivated by recent cosmological simulations, we develop an alternative approach to kinematically classify galaxies from their individual h(3) versus V/sigma signatures. Within the SAMI Galaxy Survey, we identify five classes of high-order stellar kinematic signatures using Gaussian mixture models. Class 1 corresponds to slow rotators, whereas Classes 2-5 correspond to fast rotators. We find that galaxies with similar lambda(Re)-epsilon(e) -values can show distinctly different h(3)-V/sigma signatures. Class 5 objects are previously unidentified fast rotators that show a weak h(3) versus V/sigma anti-correlation. From simulations, these objects are predicted to be disk-less galaxies formed by gas-poor mergers. From morphological examination, however, there is evidence for large stellar disks. Instead, Class 5 objects are more likely disturbed galaxies, have counter-rotating bulges, or bars in edge-on galaxies. Finally, we interpret the strong anti-correlation in h(3) versus V/sigma as evidence for disks in most fast rotators, suggesting a dearth of gas-poor mergers among fast rotators.</P>

The SAMI Galaxy Survey: revising the fraction of slow rotators in IFS galaxy surveys

van de Sande, Jesse,Bland-Hawthorn, Joss,Brough, Sarah,Croom, Scott M.,Cortese, Luca,Foster, Caroline,Scott, Nicholas,Bryant, Julia J.,d'Eugenio, Francesco,Tonini, Chiara,Goodwin, Michael,Konstantopou Oxford University Press 2017 MONTHLY NOTICES- ROYAL ASTRONOMICAL SOCIETY Vol.472 No.2

<P>The fraction of galaxies supported by internal rotation compared to galaxies stabilized by internal pressure provides a strong constraint on galaxy formation models. In integral field spectroscopy surveys, this fraction is biased because survey instruments typically only trace the inner parts of the most massive galaxies. We present aperture corrections for the two most widely used stellar kinematic quantities V/sigma and lambda(R) (spin parameter proxy). Our demonstration involves integral field data from the SAMI (Sydney-AAO Multi-object Integral-field spectrograph) Galaxy Survey and the ATLAS(3D) survey. We find a tight relation for both V/sigma and lambda(R) when measured in different apertures that can be used as a linear transformation as a function of radius, i.e. a first-order aperture correction. In degraded seeing, however, the aperture corrections are more significant as the steeper inner profile is more strongly affected by the point spread function than the outskirts. We find that V/sigma and lambda(R) radial growth curves are well approximated by second-order polynomials. By only fitting the inner profile (0.5R(e)), we successfully recover the profile out to one R-e if a constraint between the linear and quadratic parameter in the fit is applied. However, the aperture corrections for V/sigma and lambda(R) derived by extrapolating the profiles perform as well as applying a first-order correction. With our aperture-corrected lambda(R) measurements, we find that the fraction of slow rotating galaxies increases with stellar mass. For galaxies with log M-*/M-circle dot > 11, the fraction of slow rotators is 35.9 +/- 4.3 per cent, but is underestimated if galaxies without coverage beyond one R-e are not included in the sample (24.2 +/- 5.3 per cent). With measurements out to the largest aperture radius, the slow rotator fraction is similar as compared to using aperture-corrected values (38.3 +/- 4.4 per cent). Thus, aperture effects can significantly bias stellar kinematic integral field spectrograph studies, but this bias can now be removed with the method outlined here.</P>
