The influence of thermal treatments on the antioxidant activity and colour of chokeberry (aronia menocarpa) extract

Natural ingredients are an important trend in the present day food industry since manufacturers are demanding natural food dyes originating from concentrates of plant origin. However, if the use of plant extracts as technological additives is intended, their stability should be evaluated. This paper presents research on the stability of a 50% ethanolic extract of chokeberry ( Aronia melanocarpa ) from the Republic of Moldova. The extract was subjected to various thermal regimes, i.e. -2 o C for 12 hours; 4 o C for 12 hours; 40 o C for 15 minutes, 60 o C for 15 minutes, 80 o C for 15 minutes and 100 o C for 2 minutes, after which the antioxidant activity and the colour parameters (CIELab) were evaluated. Three sets of extracts were also stored for 2 weeks at -2 o C; 4 o C; and 25-30 o C and afterwards the parameters mentioned above were measured once again. Furthermore, total content of polyphenols was determined using the Folin-Ciocalteu method. The antioxidant activity was stable at temperatures under 0 o C and temperatures as high as 100 o C, as well as during storage at -2 o C, 4 o C and 25-30 o C. High temperatures however decreased the value of luminosity, and increased the redness, the yellowness and the chroma value which reached a maximum value of 55.66 after the extract was subjected to 100 o C for 2 minutes. Storage at room temperature significantly affected the luminosity of the extract by increasing its value from 42.36 to 50.22. For most treatments, the colour was stable and was not significantly modified.
Planning with Citizens: Implementation of an e-Planning Platform and Analysis of Research Needs

Citizen participation should be an essential part of an urban planning process if the needs of the local population are to be addressed. Citizen participation should also improve acceptance of private construction projects by residents that live in or near such development. A complementary form of citizen participation to public planning meetings is to permit citizen engagement via Web 2.0 technologies, which also has the potential to get citizens involved that are usually difficult to reach. We aim to build a social, i.e. participatory, planning platform that allows technology savvy citizens to inform themselves of future and ongoing development projects and to also discuss them online. In this work we discuss the functional needs and context-of-use constraints of such an e-planning platform. A conceptual model of the technical architecture is outlined and a prototype implementation is presented. This prototype is built on free and open source software components, including a social network, to enable platform adoption in other locations. Finally, we discuss the research needs that are to be addressed if the development of participatory e-planning platforms should advance.
The effects of seasonal variation on the fatty acid composition of total lipid, phospholipid, and triacylglycerol in the dorsal muscle of Capoeta trutta found in the Tigris River (Turkey)

The effects of seasonal variation on the fatty acid composition of total lipid, triacylglycerol, and phospholipid in the dorsal muscle of Capoeta trutta were assessed by gas chromatographic method. A total of 18 different fatty acids were determined in the composition of C. trutta. The variations in fatty acid composition of total lipid, triacylglycerol, and phospholipid were recorded throughout the seasons. The total polyunsaturated fatty acids (PUFA) and monounsaturated fatty acids (MUFA) were the most important groups of total lipid. Total saturated fatty acid (SFA) and total MUFA were seen to increase from spring to summer while total PUFA decreased sharply from spring to summer. These seasons corresponded to the beginning and end of the reproduction period, respectively. The major fatty acids of total lipid in all seasons were C16:0, C18:1n-9, C20:4n-6, C20:5n-3, and C22:6n-3. In the present study, n-3/n-6 ratios of total lipid were 3.20, 4.11, 1.69, and 1.45 in spring, summer, autumn, and winter, respectively. MUFA and PUFA were the most important groups of triacylglycerols. Of these, the main fatty acids were found to be C16:0, C16:1n-7, C18:1n-9, and C20:5n-3. PUFA were determined to be the most important group of phospholipids. The major fatty acids identified in the phospholipid group were C16:0, C18:1n-9, C20:5n-3, C22:5n-3, and C22:6n-3 in all seasons. In conclusion, it was shown that the fatty acid compositions in the muscle of C. trutta was significantly influenced by the seasons and that, in light of their n-3/n-6 ratios, C. trutta should be considered a desirable food in the human diet.

Selective measurements of intertwined multipolar orders: Non-Kramers doublets on a triangular lattice

Motivated by the rapid experimental progress on the spin-orbit-coupled Mott insulators, we propose and study a generic spin model that describes the interaction between the non-Kramers doublets on a triangular lattice and is relevant for triangular lattice rare-earth magnets. We predict that the system supports both pure quadrupolar orders and intertwined multipolar orders in the phase diagram. Besides the multipolar orders, we explore the magnetic excitations to reveal the dynamic properties of the systems. Due to the peculiar properties of the non-Kramers doublets and the selective coupling to the magnetic field, we further study the magnetization process of the system in the magnetic field. We point out the selective measurements of the static and dynamic properties of the intertwined multipolarness in the neutron scattering, NMR and $\mu$SR probes and predict the experimental consequences. The relevance to the existing materials such as TmMgGaO$_{4}$, Pr-based and Tb-based magnets, and many ternary chalcogenides is discussed. Our results illustrate the rich physics and the promising direction in the interplay between strong spin-orbit-entangled multipole moments and the geometrical frustration.
Modelling of Surface Identifying Characteristics Using Fourier Series

Texture and small-scale surface details are widely recognised as playing an important role in the haptic identification of objects. In order to simulate realistic textures in haptic virtual environments, it has become increasingly necessary to identify a robust technique for modelling of surface profiles. This paper describes a method whereby Fourier series spectral analysis is employed in order to describe the measured surface profiles of several characteristic surfaces. The results presented suggest that a bandlimited Fourier series can be used to provide a realistic approximation to surface amplitude profiles.
Optimizing a process‐based ecosystem model with eddy‐covariance flux measurements: A pine forest in southern France

We design a Bayesian inversion method (gradient‐based) to optimize the key functioning parameters of a process‐driven land surface model (ORganizing Carbon and Hydrology In Dynamic EcosystEms (ORCHIDEE)) against the combination of prior information upon the parameters and eddy covariance fluxes. The model calculates energy, water, and CO2 fluxes and their interactions on a half‐hourly basis, and we carry out the inversion using measurements of CO2, latent heat, and sensible heat fluxes as well as of net radiation over a pine forest in southern France. The inversion method makes it possible to assess the reduction of uncertainties and error correlations of the parameters. We designed an ensemble of inversions with different set ups using flux data over different time periods, in order to (1) identify well‐constrained parameters and loosely constrained ones, (2) highlight some model structural deficiencies, and (3) quantify the overall information gained from assimilating each type of CO2 or energy fluxes. The sensitivity of the optimal parameter values to the initial carbon pool sizes and prior parameter values is discussed and an analysis of the posterior uncertainties is performed. Assimilating 3 weeks of half‐hourly flux data during the summer improves the fit to diurnal variations, but merely improves the fit to seasonal variations. Assimilating a full year of flux data also improves the fit to the diurnal cycle more than to the seasonal cycle. This points out to the key importance of timescales when inverting parameters from high‐frequency eddy‐covariance data. We show that photosynthetic parameters such as carboxylation rates are well‐constrained by the carbon and water fluxes data and get increased from their prior values, a correction that is corroborated by independent measurements at leaf scale. In contrast, the parameters controlling maintenance, microbial and growth respirations, and their temperature dependencies cannot be robustly determined. The CO2 flux data could not discriminate between the different respiration terms. At face value, all the parameters controlling the surface energy budget can be safely determined, leading to a good model‐data fit on different timescales.

Logistics Services and Lean Six Sigma Implementation: A Case Study

Purpose This paper aims to analyze the application of Lean Six Sigma (LSS) framework for supporting continuous improvement (CI) in logistics services. Both the lean philosophy and the Six Sigma methodology have become two of the most important initiatives for CI in organizations. The combination of both alternatives – LSS – brings significant benefits for companies applying this method, and its influence in logistics services can be relevant. Design/methodology/approach A case study on the logistics services of a large consumer electronics company is performed. In this sector, high quality in logistics services is crucial. Using within-case and cross-case analyses, the paper discusses the implementation of LSS in two internal logistics processes. Findings The paper identifies important implementation aspects when applying LSS to logistics services, such as CI structure, strategic analysis, cross-functional teams and process management. Furthermore, the paper discusses the potential in logistics services of the DMAIC (define, measure, analyze, improve and control) approach and tools such as value stream mapping, SIPOC (supplier, input, process, output, and customer) and process mapping. Practical implications The paper analyzes two logistics processes where LSS has been applied – a payment process and a request-to-ship process. The analysis of both processes offers relevant information about organizational implementation in a logistics services environment about process improvement and about the use of LSS tools. Originality/value First, this paper addresses the gap in literature about LSS and logistics’ activities. Furthermore, the case company, with more than 9,000 employees and distributing its products to more than 100 countries, constitutes a valuable source of information to obtain insights into the implications of implementing LSS in logistics services.
Determining the Underlying Dimensions of Quality of Work Life (QWL) in the Nigerian Hotel Industry

Objective: The objective of this paper is to explore the underlying dimensions of quality of work life (QWL) in the Nigerian hotel industry. Research Design & Methods: With a defined population of 3.110, a sample size of 355 was determined using probability technique, which formed the participants of the study. Employing the Delphi technique, eight experts and four cycles of inputs led to a consensual number of sixty-three indicators of QWL which formed the final inventory or variables of the quality of work life dimensions used for exploratory factor analysis. Exploratory factor analysis with varimax rotation was employed. Kaiser criterion, examination of the scree plot and Horn parallel analysis (Horn, 1965) guided factor extraction. Findings: Preliminary assessment conducted confirmed the appropriateness of the dataset for factor analysis. Furthermore, based on the extraction criteria, five factors were extracted which explained 59.37% of the total variance in QWL in the Nigerian hotel industry, labelled as remuneration and benefits, job security and career satisfaction, training and opportunities for personal autonomy, home-work balance and safe and healthy environment. Implications & Recommendations: The Nigerian hotel industry should focus on the QWL factors which the study reports as most considered by employees. The study has also identified the dimensions of QWL in the Nigerian hotel industry. Contribution & Value Added: This study identifies the latent variables that show QWL in the Nigerian hotel industry, which are labelled as remuneration and benefits, job security and career satisfaction, training and personal autonomy, home-life balance and safe and healthy environment. The managerial implication is that owners and operators of hotels in Nigeria can benefit by understanding what quality of work life entails and which indicators show the concept.

1 KINEMATIC ANALYSIS OF VOWEL PRODUCTION IN GERMAN

The tense and lax vowels of German were compared, based on an analysis of the duration, amplitude and velocity characteristics of lip and tongue movement. This study examined firstly whether they show different patterns of compression over changes in speech rate, and secondly whether velocity profiles would reveal evidence of different underlying control mechanisms. CVC movements were segmented into CV, nucleus and VC portions. Speech rate affected duration of CV and VC movements similarly for tense and lax vowels. However, the effect on nucleus duration was vastly greater for the tense vowels. Analysis of the velocity profiles of CV and VC movements in terms of the ratio of peak to average velocity showed no differences between tense and lax vowels, once differences in duration were taken into account. The conclusion is that tense and lax vowels share similar control mechanisms for the elementary CV and VC movements, but differ radically in the way these elements are concatenated.
(Corrigendum) Retrieving the three-dimensional matter power spectrum and galaxy biasing parameters from lensing tomography

Aims. With the availability of galaxy distance indicators in weak lensing surveys, lensing tomography can be harnessed to constrain the three-dimensional (3D) matter power spectrum over a range of redshift and physical scale. By combining galaxy-galaxy lensing and galaxy clustering, this can be extended to probe the 3D galaxy-matter and galaxy-galaxy power spectrum or, alternatively, galaxy biasing parameters. Methods. To achieve this aim, this paper introduces and discusses minimum variance estimators and a more general Bayesian approach to statistically invert a set of noisy tomography two-point correlation functions, measured within a confined opening angle. Both methods are constructed such that they probe deviations of the power spectrum from a fiducial power spectrum, thereby enabling both a direct comparison of theory and data, and in principle the identification of the physical scale and redshift of deviations. By devising a new Monte Carlo technique, we quantify the measurement noise in the correlators for a fiducial survey, and test the performance of the inversion techniques. Results. For a relatively deep 200 deg 2 survey (¯z ∼ 0.9) with 30 sources per square arcmin, the matter power spectrum can be probed with 3 − 6σ significance on comoving scales 1 kh −1 Mpc 10 and z 0.3. For 3 lenses per square arcmin, a significant detection (∼10σ) of the galaxy-matter power spectrum and galaxy power spectrum is attainable to relatively high redshifts (z 0.8) and over aw iderk-range. Within the Bayesian framework, all three power spectra are easily combined to provide constraints on 3D galaxy biasing parameters. Therein, weak priors on the galaxy bias improve constraints on the matter power spectrum. Conclusions. A shear tomography analysis of weak-lensing surveys in the near future promises fruitful insights into both the effect of baryons on the nonlinear matter power spectrum at z 0.3 and galaxy biasing (z 0.5). However, a proper treatment of the anticipated systematics, which are not included in the mock analysis but discussed here, is likely to reduce the signal-to-noise ratio in the analysis such that a robust assessment of the 3D matter power spectrum probably requires a survey area of at least ∼10 3 deg 2 . T o investigate the matter power spectrum at redshift higher than ∼0.3, an increase in survey area is mandatory.
Classical analogues of a quantum system in spatial and temporal domains: A probability amplitude approach

Abstract We have simulated the similar features of the well-known classical phenomena in quantum domain under the formalism of probability amplitude method. The identical pattern of interference fringes of a Fabry–Perot interferometer (especially on reflection mode) is obtained through the power-broadened spectral line shape of the population distribution in the excited state with careful delineation of a coherently driven two-level atomic model. In a unit wavelength domain, such pattern can be substantially modified by controlling typical spatial field arrangement in one and two dimensions, which is found complementary to the findings of recent research on atom localization in sub-wavelength domain. The spatial dependence of temporal dynamics has also been studied at a particular condition, which is equivalent to that could be obtained under Raman–Nath diffraction controlled by spatial phase.
The Moderating Effects of School Principals’ Leadership Practices on the Workplace Spirituality and Leadership Effectiveness Relationship

Workplace spirituality and its relationship to school administrators’ leadership effectiveness, is a compelling issue for educational managment practioners. This field of study is still in its infancy stage and have not given emphasis in Malaysian educational context. The purpose of this study is to identify the moderating effects of school principals’ leadership behavior on the relationship between workplace spirituality with leadership effectiveness. Relatively, the data for this study was collected using a set of questionnaire from 989 trained teachers from 87 national secondary schools across three States of the Northern Penisular of Malaysia. The findings revealed that the level of workplace spirituality practices in the Malaysian secondary schools was exceptionaly high. Where the findings also showed concurrent adherance in supporting the hyphotesis that, workplace spirituality is positively related to leadership practices which in turn is positively related the leadership effectiveness. Meanwhile, leadership practices was identified as the moderator of the relationship between workplace spirituality and leadership effectiveness. In addition to this, the results also confirms that the workplace spirituality leads to effective leadership practices which could enhance leader effectiveness in terms of higher commitment and departmental performance. As conclusion, this study recommends that the school administrators should fully exploit the role of workplace spirituality and leadership practices as a moderator in order to increase teachers’ commitment
