Profile of gonadotropic hormone secretion in sheep with disturbed rhythm of seasonality

Molik E. , Błasiak M. , Misztal T. , Romanowicz K. , Zięba D.A. (2017): Profile of gonadotropic hormone secretion in sheep with disturbed rhythm of seasonality. Czech J. Anim. Sci., 62, 242–248. The effect of artificial conditions of a short daylight period (16 h darkness (D): 8 h light (L)) and exogenous melatonin on milk yield parameters of sheep during spring and summer was examined to determine the impact of using sheep for milk on the secretion level of gonadotrophic hormones. The research was conducted on 60 sheep lambed in February. After raising the lambs, the sheep were divided into 3 groups and assigned for dairy use (May–September). The mothers in the control Group 1 (G1) were maintained under natural daylight conditions. The sheep in Group 2 (G2) were maintained under conditions of an artificial photoperiod (16 h D : 8 h L). Meanwhile, the mothers in Group 3 (G3) were given melatonin implants. A 6-hour collection of blood from 6 sheep of each group was performed every 4 weeks. The concentrations of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in plasma were measured using radioimmunoassay. The average LH concentration in G1 gradually increased since May (5.32 ± 0.2 ng/ml), reaching the highest value in August (6.70 ± 0.2 ng/ml). In G2, the increase in LH occurred 4 weeks after the introduction of the 16 h D : 8 h L condition (6.26 ± 0.2 ng/ml). The maximum LH concentration in G3 was noted in August (7.31 ± 0.2 ng/ml). The average FSH concentration in G1 gradually increased since May (6.59 ± 0.2 ng/ml), reaching the highest value in August (10.50 ± 2.6 ng/ml). In G2, there was a significant increase in the FSH concentration in June (9.00 ± 0.3 ng/ml). In the final period during lactation, the FSH concentrations in G2 (13.51 ± 1.3 ng/ml) and G3 (13.60 ± 1.9 ng/ml) were higher than in G1. The results indicate that using sheep for milk does not inhibit the secretion of gonadotropic hormones induced by the simulation of short daylight conditions and exogenous melatonin.
Development of spray dried orange juice blended skim milk powder

Developpement d'une poudre a partir d'un melange jus d'orange-lait ecreme seche par atomisation. Le probleme actuel rencontre par les secteurs des fruits et du lait dans les pays en voie de developpement est le manque d'infrastructures de base pour traiter l'afflux de production. Plusieurs technologies et innovations ont largement ete mises au point pour les conserver et les utiliser individuellement dans les formulations d'aliments, mais beaucoup moins en combinaison. De plus, des recherches sont encore necessaires pour explorer la faisabilite de l'enrichissement du lait en vitamine C, ce qui pourrait se faire effectivement par l'incorporation de jus d'orange. Des melanges a differents taux de jus d'orange et de lait ecreme ont ete seches par atomisation, i.e. 10:90 15:85, 20:80 et 25:75, a une temperature d'alimentation de 45-50 °C et une pression d'air comprime de 0,108-0,136 MPa. Il a ete observe que les differents parametres operatoires tels que la temperature de sortie de l'air, la teneur en matiere seche totale et les proportions du melange avaient un effet important sur les caracteristiques de la poudre resultante. Quand la proportion de jus d'orange augmentait, l'acidite et la viscosite des melanges augmentait egalement en raison de la teneur elevee du jus en acide citrique. Cependant, une augmentation de l'acidite n'avait pas d'effet negatif sur la stabilite thermique des melanges avant et apres sechage par atomisation, etant donne la temperature d'alimentation peu elevee (45 °C) utilisee dans l'etude. L'augmentation de l'apport de matiere seche d'orange avait un effet negatif sur le rendement de la poudre obtenue. L'augmentation de matiere seche des melanges jusqu'a 30 % resultait dans une augmentation considerable du rendement et etait donc adoptee comme teneur optimale en matiere seche des melanges avant sechage. Des augmentations superieures de la matiere seche des melanges conduisaient a une reduction des rendements. Les temperatures de sortie d'air des equipements de sechage etaient optimisees dans une gamme de temperature de 80-85 °C pour tous les melanges. Les etudes d'evaluation sensorielle ont montre que le melange jus d'orange/lait ecreme dans un rapport 15:85 presentait les caracteristiques sensorielles desirees.
Sudden death of entanglement and teleportation fidelity loss via the Unruh effect

We use the Unruh effect to investigate how the teleportation of quantum states is affected when one of the entangled qubits used in the process is under the influence of some external force. In order to reach a comprehensive understanding, a detailed analysis of the acceleration effect on such entangled qubit system is performed. In particular, we calculate the mutual information and concurrence between the two qubits and show that the latter has a ``sudden death'' at a finite acceleration, whose value will depend on the time interval along which the detector is accelerated.
HbA1c enzymatic assay evaluation at an academic laboratory

Background: HbA1c is a well-known and widely accepted marker for monitoring glycaemic control in patients with Diabetes Mellitus. It has also been shown to predict long term microvascular complications associated with Diabetes Mellitus. As a result the International Expert Committee has endorsed HbA1c as a diagnostic marker for Diabetes Mellitus. There are several assays available for the measurement of HbA1c and the recommended assay performance is an intralaboratory coefficient of variation of <2%. The aim of the study was to evaluate the analytical performance of the HbA1c enzymatic assay on the Abbott Architect ci8200. Method: The precision, reportable range and bias were determined by following The Clinical and Laboratory Standards Institute (CLSI) EP05, EP06 and EP15 guidelines. Bias was determined by comparison between the Abbott Architect and the Biorad Variant II analyser. Results: The total impresicion for low and high controls was 1.06% and 1.8% respectively. The assay demonstrated excellent correlation with the Biorad Variant II analyser with a slope of 0.923, intercept of 0.569 and R2 of 0.978. The Bland-Altman mean difference was 0.044 between the Abbott Architect and Biorad Variant II analysers. At the diagnostic and monitoring cut-off, the bias was found to be 1.05% and 0.43% respectively. Conclusion: The new enzymatic HbA1c assay demonstrated good precision and had the advantage of rapid analysis thus prompt results reporting. The study also demonstrated acceptable agreement of the Abbott Architect and Bio-Rad Variant II methods across the measured range. Notably, the assay met analytical goals for the diagnosis and monitoring of Diabetes Mellitus using, as the total allowable error was 1.13% and 1.03% respectively, which was well below the 3% total allowable recommended error from biological data.

Evaluating the Quality of UCP-Based Framework using CK Metrics

Software effort estimation is one of the most important concerns in the software industry. It has received much attention since the last 40 years to improve the accuracy of effort estimate at early stages of software development. Due to this reason, many software estimation models have been proposed such as COCOMO, ObjectMetrix, Use Case Points (UCP) and many more. However, some of the estimation methods were not designed for object-oriented technology that actively encourages reuse strategies. Therefore, due to the popularity of UCP model and the evolution of the object-oriented paradigm, a UCP-based framework and supporting program were developed to assist software developers in building good qualities of software effort estimation programs. This paper evaluates the quality of the UCP-based framework using CK Metrics. The results showed that by implementing the UCP-based framework, the quality of the UCP-based program has improved regarding the understandability, testability, maintainability, and reusability.
Aligning Off-Balance Sheet Risk, On-Balance Sheet Risk and Audit Fees: a PLS Path Modelling Analysis

This study focuses on using the partial least squares (PLS) path modelling methodology in archival auditing research by replicating the data and research questions from prior bank audit fee studies. PLS path modelling allows for inter-correlations among audit fee determinants by establishing latent constructs and multiple relationship paths in one simultaneous PLS path model. Endogeneity concerns about auditor choice can also be addressed with PLS path modelling. With a sample of US bank holding companies for the period 2003-2009, we examine the associations among on-balance sheet financial risks, off-balance sheet risks and audit fees, and also address the pervasive client size effect, and the effect of the self-selection of auditors. The results endorse the dominating effect of size on audit fees, both directly and indirectly via its impacts on other audit fee determinants. By simultaneously considering the self-selection of auditors, we still find audit fee premiums on Big N auditors, which is the second important factor on audit fee determination. On-balance-sheet financial risk measures in terms of capital adequacy, loan composition, earnings and asset quality performance have positive impacts on audit fees. After allowing for the positive influence of on-balance sheet financial risks and entity size on off-balance sheet risk, the off-balance sheet risk measure, SECRISK, is still positively associated with bank audit fees, both before and after the onset of the financial crisis. The consistent results from this study compared with prior literature provide supporting evidence and enhance confidence on the application of this new research technique in archival accounting studies.
Trade Liberalisation and Migration Hump NAFTA as a Quasi-Natural Experiment

This paper investigates the effect of trade liberalisation on migration, using the North American Free Trade Agreement (NAFTA) as a ‘quasi-natural experiment’. I employ a data-driven and transparent event analysis methodology – synthetic control method – suitable for policy evaluation at the macro level, to assess the counterfactual scenario. This paper combines data from DEMIG-C2C and MOxLAD for the 1974–2010 period. Using regular migration from Mexico to the US as a ‘treated unit’ and the other sixteen Latin American countries to construct a ‘synthetic Mexico’, I find evidence of ‘migration hump’ following the implementation of NAFTA. The duration of the hump is estimated to be around fifteen years. This lengthy adjustment period was likely prolonged by Mexico’s subsequent financial crisis in the mid-1990s occurring in the early years of NAFTA’s implementation. The findings of this paper suggest that trade and migration are short-run complements and long-run substitutes, with a significant period of adjustment. Instead of supporting the neoclassical theory of trade and migration, our empirical evidence is more in line with the theoretical prediction of migration hump phenomenon proposed by Martin & Taylor (1996).
The Effect of Different Polyamines on Some Physiological Traits as ACC Oxidase and Superoxide Dismutase Enzymes Activity in Chrysanthemum morifolium cv. ‘Bright Golden Ann’

This experiment was conducted to determine the effect of foliar spray with polyamines on postharvest life of chrysanthemum cut flowers in the horticulture laboratory of Islamic Azad University of Rafsanjan in 2015. For this purpose, an experiment was conducted based on a completely randomized design with three replications with spermidine, spermine and putrescine treatments at 1, 2 and 3 mM concentrations. Different parameters such as vase life, quality, weight loss, dry matter percentage, chlorophyll, total soluble dissolved, protein, water uptake, ACC oxidase and SOD were measured. The results showed that all treatments significantly increased the survival and quality of flowers as compared to control. Spermidine (3 mM) resulted in maximum vase life so that after 9 days, the flowers of this treatment were of a good quality. The lowest weight loss and highest level of dissolved solids were observed in 3 mM spermidine and then, in 2 mM spermidine. ACC oxidase enzyme activity was reduced by a factor of quarter in 3 mM spermidine treatment as compared to control. On the other hand, superoxide dismutase activity in this treatment was 3 times higher than that in control. The highest amount of chlorophyll was observed in the treatment of 3 mM spermidine and putrescine. Solution uptake was increased when polyamines were applied so that the highest solution uptake was observed in the first stage of measurement in relation to 3 mM putrescine. But in the second stage of measurement, 1 mM spermine outperformed. Treatments had no significant effect on d ry matter percentage and protein amount in leaves of cut flowers. So, according to the results of this test, treatment with 3 mM spermidine is recommended as the best treatment to enhance the quality and vase life of chrysanthemum (Chrysanthemum morifolium cv. 'Bright Golden Ann') cut flowers.
Precipitation partitioning and related nutrient fluxes in a subtropical forest in Okinawa, Japan

Partition des precipitations et flux de nutriments dans une foret subtropicale d'Okinawa au Japon. La partition des precipitations entre eau arrivant directement au sol et ecoulement le long des troncs et flux hydrochimiques lies a ete etudie pendant 3 ans de janvier 1998 a decembre 2000 dans une foret feuillue a feuilles persistantes de l'ile d'Okinawa au Japon. Mensuellement des echantillons d'eau etaient collectes pour determiner les concentrations et les flux des bioelements. Les precipitations annuelles moyennes pendant la periode etudiee ont atteint 3325 mm. Les typhons jouent un role central dans l'hydrologie de la foret etudiee avec 11 typhons contribuant a 29,1 % des precipitations totales pour les 3 ans de la periode d'etude. L'eau arrivant directement au sol et l'ecoulement le long des troncs representent respectivement 53,9 % et 30,9 % des precipitations incidentes annuelles, impliquant une interception des precipitations de 15,2 %. La part importante de l'ecoulement le long des troncs pourrait etre du a la morphologie des couronnes de l'espece dominante Castanopsis sieboldii qui a des branches inclinees et des feuilles de formes concaves. Le pH des precipitations incidentes etait de 6,22, il baissait significativement avec la traversee de l'eau a travers les couronnes. Les concentrations totales de N, DOC (carbone organique dissous), K, Na, Ca et Mg montrent un modele evident d'enrichissement au niveau de l'eau traversant directement les couronnes et de l'ecoulement le long des troncs comparativement aux precipitations incidentes. La proximite de l'Ocean Pacifique influence fortement lees flux de nutriments dans le site etudie comme le montre les flux eleves de Na apportes par les precipitations incidentes (213 kg Na ha -1 an -1 ) et l'eau arrivant directement au sol et l'ecoulement le long des troncs (291 kg Na ha -1 an -1 ). La moyenne annuelle des apports de nutriments etait de (en kg ha): N total 43, P 2,6, K 76, Ca 49, Mg 30, Na 291, Al 1,8, Fe 1,0 et Mn 1,1. L'apport de DOC a atteint 361 kg de carbone par hectare et par an. L'apport eleve de nutriments par l'ensemble des precipitations arrivant au sol (eau traversant directement plus ecoulement le long des troncs) particulierement en ce qui concerne N peut etre le reflet des stress induits par l'eau salee et les insectes herbivores.
Unbalanced Optimal Transport: Geometry and Kantorovich Formulation

This article presents a new class of "optimal transportation"-like distances between arbitrary positive Radon measures. These distances are defined by two equivalent alternative formulations: (i) a "fluid dynamic" formulation defining the distance as a geodesic distance over the space of measures (ii) a static "Kantorovich" formulation where the distance is the minimum of an optimization program over pairs of couplings describing the transfer (transport, creation and destruction) of mass between two measures. Both formulations are convex optimization problems, and the ability to switch from one to the other depending on the targeted application is a crucial property of our models. Of particular interest is the Wasserstein-Fisher-Rao metric recently introduced independently by [CSPV15,KMV15]. Defined initially through a dynamic formulation, it belongs to this class of metrics and hence automatically benefits from a static Kantorovich formulation. Switching from the initial Eulerian expression of this metric to a Lagrangian point of view provides the generalization of Otto's Riemannian submersion to this new setting, where the group of diffeomorphisms is replaced by a semi-direct product of group. This Riemannian submersion enables a formal computation of the sectional curvature of the space of densities and the formulation of an equivalent Monge problem.
Tunable Snell's law for spin waves in heterochiral magnetic films

Thin ferromagnetic films with an interfacially induced DMI exhibit nontrivial asymmetric dispersion relations that lead to unique and useful magnonic properties. Here we derive an analytical expression for the magnon propagation angle within the micromagnetic framework and show how the dispersion relation can be approximated with a comprehensible geometrical interpretation in the k space of the propagation of spin waves. We further explore the refraction of spin waves at DMI interfaces in heterochiral magnetic films, after deriving a generalized Snell's law tunable by an in-plane magnetic field, that yields analytical expressions for critical incident angles. The found asymmetric Brewster angles at interfaces of regions with different DMI strengths, adjustable by magnetic field, support the conclusion that heterochiral ferromagnetic structures are an ideal platform for versatile spin-wave guides.
Relationships among Leaf Area Index, Visual Growth Rating, and Sugarcane Yield

Subjective visual growth ratings (VGR) are often used in sugarcane (Saccharum spp.) breeding programs to compare genotype performance quickly and economically. However the relationship between VGR as well as quantitative growth measurements with final yields is not well understood. Data on Leaf Area Index (LAI) and VGR obtained from a 3-yr study were used to determine the relationships among LAI, VGR, and sugarcane yield in tons of cane per hectare (TCH), and also to determine the temporal trend for the relationships of LAI and VGR with TCH across the growing season. Mean LAI increased linearly through the growing season in which data was collected. LAI was poorly related to TCH (r 2 = 0.09-0.18) early in the growing season and there was a rapid improvement in this relationship by mid-season (r 2 = 0.66-0.76), which was maintained through late-season (r 2 = 0.66-0.87). The relationship between VGR and TCH was strongest in mid-season (r 2 = 0.72-0.88) and relatively poorer early and late in the growing season (r 2 = 0.38-0.53). Similarly, there was good agreement between subjective VGR and objective LAI measurements in the middle of the growing season (r 2 = 0.65-0.77) and slightly deteriorated (r 2 = 0.54-0.57) later in the season. Results indicate that subjective VGR
APPLICATION OF FISHER'S DISCRIMINANT ANALYSIS TO CLASSIFY FOREST COMMUNITIES IN THE PAMPA BIOME

A analise discriminante de Fisher (ADF) busca realizar uma combinacao linear das variaveis independentes com objetivo de maximizar a separacao de grupos preditos em um espaco reduzido bidimensional e ainda permitir que novas observacoes sejam classificadas ou nao dentro dos grupos conhecidos a priori. Empregou-se a ADF utilizando oito variaveis estruturais obtidas de inventarios sistematicos do componente arboreo (DAP>10 cm) realizados em cinco tipos florestais (total de 5 ha) distintos no bioma Pampa do sul do Brasil. Posteriormente foram sorteadas 10 novas amostras provenientes das mesmas fitofisionomias para realizar a validacao do modelo. A AD gerou quatro funcoes discriminantes (FDs), sendo que as duas primeiras funcoes desempenharam uma capacidade de 88,4% de habilidade para discriminacao dos grupos: FD1 = 74,4% (autovalor FD1 = 33,99) e FD2 = 14% (autovalor FD2 = 6,34). Os atributos estruturais que estiveram mais relacionados com a FD1 foram riqueza de especies, altura comercial e altura total. Em FD2 prevaleceu a area basal e o diâmetro maximo atingido pelo caule. As outras FDs e variaveis estruturais apresentaram menor capacidade de discriminacao dos grupos. A AD classificou 100% dos casos nos respectivos grupos preditos, revelando a alta eficiencia das variaveis discriminadoras escolhidas. As novas amostras tambem foram classificadas em seus respectivos grupos, porem, com pequeno grau de erro. O uso da AD para a classificacao das florestas deveria ser incentivado porque o metodo e simples e os resultados sao estatisticamente mais confiaveis do que outros metodos descritivos da estatistica multivariada que sao amplamente utilizados.
Cold electron heating by EMIC waves in the plasmaspheric plume with observations of the Cluster satellite

We report in situ observations by the Cluster spacecraft of plasmaspheric electron heating in the plasmaspheric plume. Electron heating events were accompanied by enhancements of electromagnetic ion cyclotron (EMIC) waves in the increased density ducts on the negative density gradient side for two substructures of the plasmaspheric plume. Electron heating is much stronger for the pitch angle of 0° and 180° than for the pitch angle of 90°. Theoretical calculations of the Landau resonant interaction between electrons and observed EMIC waves demonstrate that Landau damping of oblique EMIC waves is a reasonable candidate to heat cold electrons in the presence of O+ ions in the outer boundary of the plasmaspheric plume. Therefore, this observation is considered in situ evidence of plasmaspheric electron heating through Landau damping of EMIC waves in plasmaspheric plumes.
