Determination of Ascorbic Acid Content of Some Fruit Juices and Wine by Voltammetry Performed at Pt and Carbon Paste Electrodes
Authors: Pisoschi Aurelia Magdalena , Pop Aneta , Negulescu Gheorghe Petre , Pisoschi Aurel
Published: February 2011

A method was developed for assessing ascorbic acid concentration in fruit juices and wine by differential pulse voltammetry. The oxidation peak for ascorbic acid occurs at about 530 mV (versus SCE) on a Pt strip working electrode and at about 470 mV on a carbon paste working electrode. The influence of the operational parameters like the pulse amplitude and the pulse period on the analytical signal was investigated. The obtained calibration graph shows a linear dependence between the peak height and ascorbic acid concentration within the range 0.31-20 mM with a Pt working electrode, and within the range 0.07-20 mM with a carbon paste working electrode. The equation of the calibration graph was y = 21.839x + 35.726, r2 = 0.9940, when a Pt strip electrode was used (where y represents the value of the current intensity measured for the peak height, expressed as µA and x the analyte concentration, as mM). R.S.D. = 2.09%, n = 10, Cascorbic acid = 2.5 mM. The equation of the calibration graph was y = 3.4429x + 5.7334, r2 = 0.9971, when a carbon paste electrode was used (where y represents the value of intensity measured for the peak height, expressed as µA and x the analyte concentration, as mM). R.S.D. = 2.35%, n = 10, Cascorbic acid = 2.5 mM. The developed method was applied to ascorbic acid assessment in fruit juices and wine. The ascorbic acid content determined ranged between 6.83 mg/100 mL juice for soft drinks (Fanta Madness) and 54.74 mg/100 mL for citrus (lemon) juices obtained by squeezing fruit. Different ascorbic acid concentrations (from standard solutions) were added to the analysed samples, the degree of recovery being comprised between 94.74 and 104.97%. The results of ascorbic acid assessment by differential pulse voltammetry were compared with those obtained by cyclic voltammetry. The results obtained by the two methods were in good agreement.
A Target Coverage Scheduling Scheme Based on Genetic Algorithms in Directional Sensor Networks
Authors: Gil Joon-Min , Han Youn-Hee
Published: February 2011

As a promising tool for monitoring the physical world, directional sensor networks (DSNs) consisting of a large number of directional sensors are attracting increasing attention. As directional sensors in DSNs have limited battery power and restricted angles of sensing range, maximizing the network lifetime while monitoring all the targets in a given area remains a challenge. A major technique to conserve the energy of directional sensors is to use a node wake-up scheduling protocol by which some sensors remain active to provide sensing services, while the others are inactive to conserve their energy. In this paper, we first address a Maximum Set Covers for DSNs (MSCD) problem, which is known to be NP-complete, and present a greedy algorithm-based target coverage scheduling scheme that can solve this problem by heuristics. This scheme is used as a baseline for comparison. We then propose a target coverage scheduling scheme based on a genetic algorithm that can find the optimal cover sets to extend the network lifetime while monitoring all targets by the evolutionary global search technique. To verify and evaluate these schemes, we conducted simulations and showed that the schemes can contribute to extending the network lifetime. Simulation results indicated that the genetic algorithm-based scheduling scheme had better performance than the greedy algorithm-based scheme in terms of maximizing network lifetime.
Effect of Neuromuscular Electrical Muscle Stimulation on Energy Expenditure in Healthy Adults
Authors: Hsu Miao-Ju , Wei Shun-Hwa , Chang Ya-Ju
Published: February 2011

Weight loss/weight control is a major concern in prevention of cardiovascular disease and the realm of health promotion. The primary aim of this study was to investigate the effect of neuromuscular electrical stimulation (NMES) at different intensities on energy expenditure (oxygen and calories) in healthy adults. The secondary aim was to develop a generalized linear regression (GEE) model to predict the increase of energy expenditure facilitated by NMES and identify factors (NMES stimulation intensity level, age, body mass index, weight, body fat percentage, waist/hip ratio, and gender) associated with this NMES-induced increase of energy expenditure. Forty sedentary healthy adults (18 males and 22 females) participated. NMES was given at the following stimulation intensities for 10 minutes each: sensory level (E1), motor threshold (E2), and maximal intensity comfortably tolerated (E3). Cardiopulmonary gas exchange was evaluated during rest, NMES, and recovery stage. The results revealed that NMES at E2 and E3 significantly increased energy expenditure and the energy expenditure at recovery stage was still significantly higher than baseline. The GEE model demonstrated that a linear dose-response relationship existed between the stimulation intensity and the increase of energy expenditure. No subject’s demographic or anthropometric characteristics tested were significantly associated with the increase of energy expenditure. This study suggested NMES may be used to serve as an additional intervention for weight loss programs. Future studies to develop electrical stimulators or stimulation electrodes to maximize the comfort of NMES are recommended.

M. Cacouros, Marginalia de Chortasménos dans un opuscule logique dû à Prodromènos (Vatican, gr. 1018). — Jean Chortasménos (1370-1431) s'est vivement intéressé à la logique aristotélicienne et, en particulier, aux Analytiques. La découverte de notes marginales de sa main dans le Vatican, gr. 1018, f. 1, présente un intérêt particulier. Ce manuscrit de contenu logique date du 15e siècle, à l'exception précisément du f. 1, autographe de Néophytos Prodromènos (milieu 14e s.), qui comprend son commentaire aux Catégories d'Aristote. Les notes de lecture de Chortasménos enrichissent un passage qui se rapporte aux quatre méthodes à suivre dans toute enquête scientifique. Or cet exposé appartient d'habitude à l'exégèse des Seconds Analytiques et non pas à celle des Catégories, ce qui a incité Chortasménos à rapprocher le passage en question des Seconds Analytiques — deux points sur les trois qu'il donne sont en rapport avec cette œuvre d'Aristote ; il avait donc probablement une grande familiarité avec cette exégèse et ces notes confirment l'intérêt qu'il portait aux Analytiques et qu'on a pu mettre en valeur ailleurs.

The Origins of the Cult of Saint George

REB 53 1995 France p. 295-326

Ch. Walter, The Origins of the Cult of Saint George. — In this article, the author does not return to the traditional scholar's thankless task of attempting to discover a «historical» figure beneath an incrustation of legends, although he considers that these legends could be fruitfully studied under the guise of contes populaires. He concentrates rather on the «meta-historical» Saint George, notably as he is presented in the Life of Theodore of Sykeon. To establish the character of the «meta-historical» Saint George, it is not only necessary to take into account the clichés long since currently used for saints and martyrs, but also to delineate the prestigious contemporaries of Saint George : Thecla, Menas, Demetrius, etc., for none of whom was there a regular «set up» of miracula, eulogia, relics, sanctuary, etc. In the case of Saint George, it seems clear that a portrait-type of this exceptionally handsome young man was established earlier than any icon known to exist today. It was devotion to his icon, accompanied by beneficent apparitions, rather than veneration of his relics or fréquentation of his sanctuary, which maintained his cult up to this day.

Failler, Ferran d'Aunès gentilhomme catalan. — Ferran d'Aunés était l'un des chefs de la Compagnie catalane qu'Andronic II Palaiologos fit venir à Constantinople à l'automne 1303 pour combattre les Turcs en Asie Mineure. Mis à la tête de la flotte par Roger de Flor, Ferran d'Aunés reçut de l'empereur la dignité d'amiral et fut marié à la fille de Rhaoul Pachys. Promu domestique des scholes au printemps 1305, il mourut dans l'incendie qui embrasa la maison de son beau-père.

La date de la prise définitive d'Éphèse par les Turcs a été fixée au 24 octobre 1304, sur la foi d'un colophon de Michel Loulloudès.

La première série (527-609) offre des parallèles remarquables avec la Chronique de Jean Malalas et surtout celle de Théophane, mais elle se clôt au règne de Phocas (†610) comme celle de Jean d'Antioche, l'un des utilisateurs de Malalas : ce qui permettrait de supposer une filiation Jean Malalas (6e s.) — Jean d'Antioche (7e s.) — l'Epitomè (7e s.) — Théophane (9e s.)- La seconde (465-562), elle aussi très proche de Jean Malalas et surtout de Théophane, pourrait dépendre de la Chronique de Basile de Cilicie (6e s.), qui s'étendait du règne de Marcien (450-457) jusque vers 555/560 : c'est en effet à cet auteur que renvoie la notice anonyme conservée dans le codex Baroccianus gr. 142, l'un des autres témoins de l'Épitomè.

La question de l'Union des Églises (13e-15e siècle) : historiographie et perspectives
Authors: Blanchet Marie-Hélène
Published: February 2011

The attempts at reunion of the Roman and Orthodox Churches, from the antecedents of the Council of Lyons (1274) to the Council of Florence (1439), have brought forth an abundant historical literature characterised for a long time by the confessional commitment of its authors in Western as well as Eastern Europe. Historical interpretations of the Union have been heavily influenced by the various politico-religious contexts in which they were produced, following closely the evolution of the relations between Rome and Orthodoxy down to the Ecumenism of the second half of the twentieth century. Recent studies aim at a more global consideration of the question, beyond its strictly religious significance: focus is more and more placed on the nature of the reception of the Union in Byzantium and on the conflicts that it has provoked within Greek society.
Giacomo Badoer et kyr Théodôros Batatzès, « chomerchier di pesi » à Constantinople (flor. 1401-1449)
Authors: Ganchou Thierry
Published: February 2011

The Libro dei Conti of the Venetian merchant Giacomo Badoer who lived in Constantinople from 1436 to 1440 makes frequent mention of a strange figure referred to as '[Chir] Todaro Vatazi [patron de nave de Chandia] [chomerchier di pesi].' In fact Badoer here speaks of of two different persons named Theodore Batatzes: the one a Cretan shipowner (ob. 1439), the other a Byzantine 'chomerchier di pesi.' Venetian notarial documents from Crete allow us to distinguish the activitiy of each and, more particularly, to trace the career of the Byzantine Kyr Theodoros Batatzes, attested as a commercial agent and benefactor of an Athonite monastery until 1449. The problem posed by these identical names, complicated further by a third contemporary Theodore Vatatzes, is studied in connexion with the diffusion of the family name Vatatzes in the Greek-speaking territory subject to various political authorities in the fifteenth century. Finally, the office of 'chomerchier di pesi' is discussed, drawing on our meagre sources for the Byzantine financial system on the eve of the fall of Constantinople.

Une première édition des œuvres de Joseph Bryennios : les Traités adressés aux Crétois
Authors: Bazini Hélène
Published: February 2011

Joseph Bryennios (ca. 1350-1431) had personally collected and edited the homilies he had delivered at Constantinople (ca. 1404-1422). This 'Constantinople Homiliary' is reproduced in the first two volumes of the edition by Boulgaris (Leipzig 1768). In this paper, the author shows that before the Constantinople Homiliary, Bryennios had in all likelyhood collected and edited a group of works related to Crete, where he had lived for twenty years (ca. 1382- 1402). These Treatises addressed to the Cretans are preserved in four manuscripts. The history and contents of the corpus are studied here. It comprises the works by Bryennios edited by Boulgaris in his third volume (Leipzig 1784), as well as other texts that have been published since then, but without being situated in the corpus (the Acts of the Council of Cyprus and the Discussion with an Ishmaelite); finally, three unpublished treatises also belong to that corpus.

Le manuscrit grec Coislin. 305 : la version primitive de la Chronique de Georges le Moine
Authors: Afinogenov Dmitri
Published: February 2011

La question de l'antériorité entre les deux versions principales de la Chronique de Georges le Moine peut être examinée à nouveaux frais si l'on prend en considération les faits suivants : 1). la traduction vieux-slavonne de ce texte (Letovnik) est faite à partir d'un manuscrit grec de cette version, dont le texte est meilleur que celui des manuscrits grecs P (Coislinianus 305) et Q ; il en résulte que beaucoup d'erreurs de P doivent être considérées comme des fautes de copie ; 2). P comprend des citations plus développées que celles de la vulgata, provenant de sources particulièrement rares, comme la Vie de S. Nicétas de Médikion dans sa forme complète (celle-ci n'ayant pas été conservée en grec) ; 3) des passages (au moins cinq) de la vulgata qui font tous défaut à P pouvant être identifiés comme des emprunts (ou des allusions) à la version originale de la Lettre des trois patriarches d'Orient à l'empereur Théophile. Ces faits permettent de réfuter les arguments anciens avancés en faveur de l'antériorité de la vulgata, ou, en tout cas, confirment directement l'antériorité da la version comprise dans P. Ainsi, l'état primitif de la Chronique de Georges le Moine, de toute probabilité rédigé en 846/847, est représenté par ce manuscrit et, aussi, par la traduction vieux-slavonne (Letovnik), alors que la vulgata est le fruit d'une révision datant du dernier quart du 9e siècle.

Béatrice Caseau, Syméon Stylite l'Ancien entre puanteur et parfum. - La puanteur est le plus souvent associée avec le péché dans la littérature chrétienne antique, elle est la conséquence de certaines maladies qui sont perçues comme un châtiment divin. Cependant, quelques saints ont choisi d'éprouver par eux-mêmes la douleur et le rejet liés à la mauvaise odeur dégagée par les plaies infectées. Par cette expérience, ils apprennent à éprouver de la compassion pour l'humanité et la patience dans la souffrance. En cela, ils reprennent le modèle de Job. Les différentes Vies de Syméon stylite l'ancien montrent une variété dans la manière d'évoquer la puanteur du saint, liée plutôt au choix de l'hagiographe qu'à une différence culturelle entre monde latin, monde grec et monde syriaque.

Loss of Residual Renal Function was Not Associated with Glycemic Control in Patients on Peritoneal Dialysis
Authors: Sung Su-Ah , Hwang Young-Hwan , Kim Sejoong , Kim Sung Gyun , Oh Jieun , Chung Wookyung , Lee So-Young , Ahn Curie , Oh Kook-Hwan
Published: February 2011

Background

Better glycemic control has been reported to slow the progression of nephropathy in predialysis diabetic patients. However, the relationship between glycemic control and residual renal function (RRF) in patients on peritoneal dialysis (PD) is uncertain.

Methods

89 incident diabetic patients on PD were recruited from 5 centers. We measured glomerular filtration rate (GFR) and hemoglobin A1c (HbA1c) within 2 months (baseline) after the start of PD and at 6 and 12 months. GFR was calculated as the average of renal creatinine and urea clearances. We analyzed whether mean HbA1c was associated with change in GFR (ΔGFR) over 1 year.

Results

During the first year of PD, ΔGFR was -1.7 ± 3.4 mL/min/1.73 m2 and was not affected by mean HbA1c. Acute hemodialysis before starting PD and mean arterial diastolic pressure were related to the decline of GFR in a multivariate analysis.

Conclusion

Glycemic control was not associated with change in RRF in diabetic patients during the first year after starting PD.
Biomimetics inspired surfaces for drag reduction and oleophobicity/philicity
Authors: Bhushan Bharat
Published: February 2011

The emerging field of biomimetics allows one to mimic biology or nature to develop nanomaterials, nanodevices, and processes which provide desirable properties. Hierarchical structures with dimensions of features ranging from the macroscale to the nanoscale are extremely common in nature and possess properties of interest. There are a large number of objects including bacteria, plants, land and aquatic animals, and seashells with properties of commercial interest. Certain plant leaves, such as lotus (Nelumbo nucifera) leaves, are known to be superhydrophobic and self-cleaning due to the hierarchical surface roughness and presence of a wax layer. In addition to a self-cleaning effect, these surfaces with a high contact angle and low contact angle hysteresis also exhibit low adhesion and drag reduction for fluid flow. An aquatic animal, such as a shark, is another model from nature for the reduction of drag in fluid flow. The artificial surfaces inspired from the shark skin and lotus leaf have been created, and in this article the influence of structure on drag reduction efficiency is reviewed. Biomimetic-inspired oleophobic surfaces can be used to prevent contamination of the underwater parts of ships by biological and organic contaminants, including oil. The article also reviews the wetting behavior of oil droplets on various superoleophobic surfaces created in the lab.
Do We Need Core Sets of Fibromyalgia Domains? The Assessment of Fibromyalgia (and Other Rheumatic Disorders) in Clinical Practice
Authors: WOLFE FREDERICK , HASSETT AFTON L. , KATZ ROBERT S. , MICHAUD KALEB , WALITT BRIAN
Published: February 2011

Objective.

An OMERACT consensus process recommended domains for investigation in fibromyalgia (FM) clinical trials. We used patient data to investigate variable importance in the determination of patient global and health-related quality of life (HRQOL) in FM and non-FM patients to determine whether variables were valued differently in FM compared with non-FM states.

Methods.

We used ACR 2010 diagnostic FM criteria modified for epidemiological and clinical research to identify patients with rheumatoid arthritis (RA; N = 5884) with and without FM, and also characterized previously diagnosed patients with FM (N = 808) as to current criteria status. We measured variable importance by multivariable regression, decomposing regression variance by averaging over model orderings. We examined the distributions of key variables in the various disorders, and the distributions as a function of a FM severity index (fibromyalgianess).

Results.

Out of 9 measures, pain, Health Assessment Questionnaire disability index, and fatigue explained more than 50% of explainable variance (50.49%–56.59%). Explained variance was similar across all disorders and diagnostic groups. In addition, the SF-36 physical component summary score varied across disorders as a function of fibromyalgianess.

Conclusion.

The main determinants of global severity and HRQOL in FM are pain, function, and fatigue. But these variables are also the main determinants in RA and other rheumatic diseases. The content and impact of FM, whether measured by discrete variables or a fibromyalgianess scale, seems to be independent of diagnosis. These data argue for a common set of variables rather than disease-specific variables. Clinical use is supported and enhanced by simple measures.

Objective.

To compare survival of patients with connective tissue disease-associated interstitial lung disease (CTD-ILD) versus idiopathic pulmonary fibrosis (IPF) and patients with systemic sclerosis-associated ILD (SSc-ILD) versus other CTD-ILD followed at our center.

Methods.

We used the Stanford ILD database, which contains prospectively collected information on patients with ILD evaluated at our tertiary care center from 2002 to 2009. Survival at last followup from time of ILD diagnosis was calculated using the Kaplan-Meier estimator. Prognostic factors for survival in the overall cohort (IPF and CTD-ILD) and in the CTD-ILD group were identified with univariate and multivariate Cox regression models.

Results.

Of 427 patients with ILD, 148 (35%) had IPF and 76 (18%) had CTD-ILD at the baseline visit. The cumulative incidence of CTD was 4%. After a median followup of 4 years, 67 patients (36.4%) had died and 4 (2.2%) were lost to followup. Patients with IPF (n = 122) and CTD-ILD (n = 62) experienced similar survival rates (5-year survival about 50%). Patients with SSc-ILD (n = 24) experienced better survival than those with other CTD-ILD (n = 38), with 1-year, 3-year, and 5-year survival rates of 100%, 90%, and 77%, respectively, versus 78%, 42%, and 38% (p = 0.01). The presence of SSc in patients with CTD-ILD decreased the risk of death by > 80% even after correcting for age at ILD diagnosis, sex, and ethnicity (HR = 0.17, 95% CI 0.04–0.83).

Conclusion.

Survival in patients with SSc-ILD was better than in patients with other CTD-ILD, potentially related to routine screening for and early detection of ILD in patients with SSc at our center.

Objective.

The common polymorphism rs4994 [c. T387C, p. Trp64Arg (W64R)] of the lipolysis regulator beta-3-adrenergic receptor (ADRB3) was identified as a marker in the pathogenesis of hyperuricemia. As gout is characterized by elevated serum concentrations of uric acid, we investigated ADRB3 as a potential candidate for gout.

Methods.

This was a prospective case-control study in a group of 421 male patients with gout and 312 gout-free male controls to genotype the single-nucleotide polymorphism rs4994 of ADRB3 gene.

Results.

Our results showed that the C allele carrier confers a significantly higher risk for development of gout [chi-square = 4.91, df = 1, p = 0.027, OR 1.95 (adjusted by age, total cholesterol level, and body mass index), 95% CI 1.22–3.13 by dominant mode]. There was significantly higher uric acid level in carriers of the Arg64/Arg64 genotype in controls compared to non-carriers (480.5 mmol/l vs 315.0 mmol/l, respectively).

Conclusion.

ADRB3 rs4994 polymorphism is a potential candidate for the pathogenesis of gout in a male Chinese population.
Individual Genetic Variations Directly Effect Polarization of Cytokine Responses to Superantigens Associated with Streptococcal Sepsis: Implications for Customized Patient Care
Authors: Nooh Mohammed M. , Nookala Suba , Kansal Rita , Kotb Malak
Published: February 2011

Host immunogenetic variations strongly influence the severity of group A streptococcus sepsis by modulating responses to streptococcal superantigens (Strep-SAgs). Although HLA-II–DR15/DQ6 alleles strongly protect against severe sepsis, HLA-II–DR14/DR7/DQ5 alleles significantly increase the risk for toxic shock syndrome. We found that, regardless of individual variations in TCR-Vβ repertoires, the presentation of Strep-SAgs by the protective HLA-II–DR15/DQ6 alleles significantly attenuated proliferative responses to Strep-SAgs, whereas their presentation by the high-risk alleles augmented it. Importantly, HLA-II variations differentially polarized cytokine responses to Strep-SAgs: the presentation of Strep-SAgs by HLA-II–DR15/DQ6 alleles elicited significantly higher ratios of anti-inflammatory cytokines (e.g., IL-10) to proinflammatory cytokines (e.g., IFN-γ) than did their presentation by the high-risk HLA-II alleles. Adding exogenous rIL-10 significantly attenuated responses to Strep-SAgs presented by the high-risk HLA-II alleles but did not completely block the response; instead, it reduced it to a level comparable to that seen when these superantigens were presented by the protective HLA-II alleles. Furthermore, adding neutralizing anti–IL-10 Abs augmented Strep-SAg responses in the presence of protective HLA-II alleles to the same level as (but no higher than) that seen when the superantigens were presented by the high-risk alleles. Our findings provide a molecular basis for the role of HLA-II allelic variations in modulating streptococcal sepsis outcomes and suggest the presence of an internal control mechanism that maintains superantigen responses within a defined range, which helps to eradicate the infection while attenuating pathological inflammatory responses that can inflict more harm than the infection itself.
Prospective Merger Between Car-Parrinello and Lattice Boltzmann Methods for Quantum Many-Body Simulations
Authors: Succi Sauro , Palpacelli Silvia
Published: February 2011

Formal analogies between the Car-Parrinello (CP) ab-initio molecular dynamics for quantum many-body systems, and the Lattice Boltzmann (LB) method for classical and quantum fluids, are pointed out. A theoretical scenario, whereby the quantum LB would be coupled to the CP framework to speed-up many-body quantum simulations, is also discussed, together with accompanying considerations on the computational efficiency of the prospective CP-LB scheme.
Lattice Boltzmann Simulation of Droplet Generation in a Microfluidic Cross-Junction
Authors: Liu Haihu , Zhang Yonghao
Published: February 2011

Using the lattice Boltzmann multiphase model, numerical simulations have been performed to understand the dynamics of droplet formation in a microfluidic cross-junction. The influence of capillary number, flow rate ratio, viscosity ratio, and viscosity of the continuous phase on droplet formation has been systematically studied over a wide range of capillary numbers. Two different regimes, namely the squeezinglike regime and the dripping regime, are clearly identified with the transition occurring at a critical capillary number Cacr. Generally, large flow rate ratio is expected to produce big droplets, while increasing capillary number will reduce droplet size. In the squeezing-like regime (Ca ≤ Cacr), droplet breakup process is dominated by the squeezing pressure and the viscous force; while in the dripping regime (Ca ≤ Cacr), the viscous force is dominant and the droplet size becomes independent of the flow rate ratio as the capillary number increases. In addition, the droplet size weakly depends on the viscosity ratio in both regimes and decreases when the viscosity of the continuous phase increases. Finally, a scaling law is established to predict the droplet size.
Microflow Simulations via the Lattice Boltzmann Method
Authors: Prasianakis Nikolaos , Ansumali Santosh
Published: February 2011

The exact solution to the hierarchy of nonlinear lattice Boltzmann kinetic equations, for the stationary planar Couette flow for any Knudsen number was presented by S. Ansumali et al. [Phys. Rev. Lett., 98 (2007), 124502]. In this paper, simulation results at a non-vanishing value of the Knudsen number are compared with the closed-form solutions for the higher-order moments. The order of convergence to the exact solution is also studied. The lattice Boltzmann simulations are in excellent agreement with the exact solution.
Intercomparison of column aerosol optical depths from CALIPSO and MODIS-Aqua

Published: February 2011

Abstract. The Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) is carried on the CALIPSO satellite and has acquired global aerosol profiles since June 2006. CALIPSO is flown in formation with the Aqua satellite as part of the A-train satellite constellation, so that a large number of coincident aerosol observations are available from CALIOP and the MODIS-Aqua instrument. This study compares column aerosol optical depth at 0.532 μm derived from CALIOP aerosol profiles with MODIS-Aqua 0.55 μm aerosol optical depth over the period June 2006 through August 2008. The study is based on the CALIOP Version 2 Aerosol Layer Product and MODIS Collection 5. While CALIOP is first and foremost a profiling instrument, this comparison of column aerosol optical depth provides insight into quality of CALIOP aerosol data. It is found that daytime aerosol optical depth from the CALIOP Version 2 product has only a small global mean bias relative to MODIS Collection 5. Regional biases, of both signs, are larger and biases are seen to vary somewhat with season. Good agreement between the two sensors in ocean regions with low cloudiness suggests that the selection of lidar ratios used in the CALIOP aerosol retrieval is sufficient to provide a regional mean AOD consistent with that retrieved from MODIS. Although differences over land are observed to be larger than over ocean, the bias between CALIOP and MODIS AOD on a regional-seasonal basis is found to be roughly within the envelope of the MODIS expected uncertainty over land and ocean. This work forms a basis for further comparisons using the recently released CALIOP Version 3 data.

Abstract. Significant land use changes have been observed in West Africa, particularly in the Sahel region where climatic and demographic factors have led to a rise in cultivated areas, in recent decades. These changes caused strong modifications in the water cycle and in river regimes. By comparing the rainfall-runoff relationships for two periods (1991–1994 and 2004–2010) in two small neighbouring catchments (approx. 0.1 km2 each) of the Sahel, this study highlights the different hydrological consequences of land use change, particularly vegetation clearing and the consequent degradation of topsoil. Runoff increased in the upper basin, while it decreased in the lower basin, due to a strong increase in in-channel infiltration. Flood peak durations have become shorter in the downstream part of the catchment due to the huge increase of runoff water transmission losses within the gullies. Further study will consist of equipping one of the catchments with anti-erosion devices (mainly "half-moons" and terraces) in order to evaluate the influence of anti-erosion devices on runoff and suspended load.

The paper presents an overview of the present perception of bio-food labeling by consumers in Slovakia. Analyses were realized by the questionnaire survey organized in the period December 2009 to January 2010. In the survey, 388 respondents were interviewed. From the methodological aspect, basic approaches of descriptive statistics have been used, as well as methods of association measurement. The test of robustness tested Chi-Square statistic. The robustness have been judged based on the p-values. Correlations have been tested through the Contingency coefficient and Cramer´s V coefficient. The survey showed that dependency knowledge of logos was confirmed in terms of knowledge of bio-food, education, type of employment, study at FBP faculty and in terms of choice of organic foods by manufacturers. Students of FBP  knows more bio-food logos than other respondents. The second highest dependency was confirmed within selection of bio-food produced individual manufacturers.

Published: February 2011

The aim of this study was to monitor isolates of Alternaria and Fusarium species, isolated from Slovak wheat grains in 2006 - 2008, for ability to produce mycotoxins and to estimate a potential contamination risk of wheat grains by mycotoxins. Toxinogenity of isolates was analyzed by means of thin layer chromatography (TLC) and liquid chromatography coupled to tandem mass spectrometry (LC/MS/MS). A total of 302 Alternaria species (A. alternata, A. arborescens, A. infectoria, A. tenuissima) were tested by TLC method and a total of 238 Fusarium species (F. acuminatum, F. avenaceum, F. crookwellense, F. culmorum, F. equiseti, F. graminearum, F. langsethiae, F. oxysporum, F. poae, F. proliferatum, F. semitectum, F. solani, F. sporotrichioides, F. subglutinans, F. tricinctum, F. verticillioides) were analyzed by TLC as well as LC/MS/MS method. All Alternaria sp. strains, excepting A. infectoriastrains, showed high potention to produce altenuen, alternariol and alternariol monomethylether. None of A. infectoriaspecies strains produced any mycotoxins analyzed in this study. Fusarium sp. strains demonstrated, according to toxicology specificity, ability to produce trichothecenes (deoxynivalenol, diacetoxyscirpenol, fusarenone X, HT-2 toxin, monoacetoxyscirpenol, neosolaniol, nivalenol, T-2 toxin), fumonisins, zearalenones, moniliformine and rarely mentioned toxins as aurofusarine, beauvericine, enniatins, equisetin and chlamydosporol. High potential production of mycotoxins and wide spectrum of toxic metabolites represent high risk of toxins production in real field conditions.
