Agronomic characteristics and nutritive value of elephant grass clones managed under rotational stocking during the dry period.

This study aimed to evaluate the agronomic characteristics and nutritional value of two clones of elephant grass (CNPGL 00-1-3 and BRS Kurumi) operating under rotational stocking in the dry season. A completely randomized design with repeated measures (grazing cycles) and three replicates (paddocks) was used. Clones were managed under rotational stocking with a defoliation interval of 24 days and four days of occupation of paddocks, using Holstein x Gyr heifers with mean body weight of 150 kg. The evaluations were conducted in April/May, May/June, June/July and July/August 2010. Green forage mass was influenced by clone and grazing cycle, with higher mean value observed for CNPGL 03-01-00, which was 17% higher than the value observed for BRS Kurumi, and there was decreased of dry mass of green forage with the advance of grazing cycles. Leaf mass was influenced only by grazing cycle, with gradual reduction from the first to the third cycle. However, in fourth cycle was increase in biomass of leaves, which did not differ from that observed in the second cycle. There was interaction for dry matter production of stem, being observed differences in the first and third cycles for the clones. There was no effect of the factors studied for the production of senescent material. The leaf:stem ratio was influenced by grazing cycles, with interaction of the factors studied. The clone BRS Kurumi kept the leaf:stem ratio stable over the cycles, while clone CNPGL 1-3-00 presented a decrease in leaf:stem ratio from first until to third cycle. The content of crude protein (PB) was not influenced by the factors studied, with average values of 15.3% and 15.8% PB for the CNPGL 00-1-3 and BRS Kurumi clones. Neutral detergent fiber (NDF) and the in vitro dry matter digestibility (IVDMD) were affected only by grazing cycles. The highest values of NDF were observed in the three first grazing cycles, with values of 55.5%, 56.0% and 55.7% from the first to the third grazing cycle, respectively, while in the fourth cycle was obtained the value of 50.5%. There was a decrease in the IVDMD until the third cycle. In the fourth cycle the IVDMD values were similar to the first cycle. The clones did not differ in relation to biomass production, morphological composition and nutritional value, during the dry season.
Crystallization Behavior of Poly(p-dioxanone-co-glycolide) Copolymers

Poly(p-dioxanone-co-glycolide) (PDG) copolymers with high proportion of p-dioxanone (pDO) were synthesized by ring-opening polymerization of pDO and glycolide (GA) with stannous octoate-dodecanol as the initiator. The cooling crystallization and isothermal crystallization of PDG were studied by DSC and X-ray. The influence of copolymer composition on the crystallization behavior was discussed. With the increase of GA in the copolymer, the crystallinity of PDG was decreased firstly and then increased, but crystallization heat and crystallization speeds were weakened. The results provided guidance for determining copolymerization parameters and melt spinning of PDG.
Percutaneous Radiofrequency Ablation versus Surgical Resection for the Treatment of Small Hepatic Carcinoma: A Meta-analysis

Aims: To evaluate the curative effect of percutaneous radiofrequency ablation (PRFA) versus surgical resection (SR) for the treatment of small hepatic carcinoma. Methods: Cochrane Library, Medline, Pubmed, CNKI, WanFang, VIP databases were searched from January 1990 to March 2013, then clinical control studies comparing curative effects of PRFA with SR in treatment of small hepatic carcinoma were acquired and reviewed. Qualities of these studies were evaluated. Publication bias was also assessed by using a funnel plot. Then primary outcomes, namely overall survival rates, disease-free survival rates and postoperative complication, were abstracted to conduct a combined analysis by using fixed or random effects model. Results: A total of eight studies involving 1287 patients were included in our study. The PRFA group has a lower overall survival rates over the SR group in 1 year (OR, 0.62; 95% confidence interval [CI], 0.43-0.89; P = 0.009), 3 years (OR, 0.44; 95% CI, 0.27-0.72; P=0.001), and 5 years (OR, 0.49; 95% CI, 0.35-0.68; P＜0.0001). The PRFA group has a lower disease-free survival rates over the SR group in 1 year (OR, 0.63; 95% CI, 0.49-0.82; P=0.0006), 3 years (OR, 0.45; 95% CI, 0.30-0.67; P=0.0001), and 5 years (OR, 0.46; 95% CI, 0.33-0.64; P＜0.00001). The postoperative complication of the PRFA group was lower than the SR group (OR, 0.21; 95% CI, 0.08-0.56; P＜0.00001). Conclusion: PRFA had lower overall survival rates after surgery and disease-free survival than SR, but it has a lower incidence of postoperative complications. Then PRFA, acted as an operation with smaller invasion and shorter hospitalization time, would be a good choice for the patients with hepatic carcinoma who is reluctant to be treated by SR.
The Sound System of Zubairi Arabic: A Phonological Sketch

The present paper sheds light on Zubairi phonology from a segmental standpoint. It covers five major issues: the consonantal system, the vowel system, phonontactics, geminate and syllable structure. As for the consonantal system, Zubairi Arabic has a relatively conservative consonantal inventory on functional and phonetic grounds. They are categorized into two main classes: obstruents and sonorants. The Zubairi vowel system includes 8 vowel phonemes whose distinctive function and length differences are greatly affected by some environments. In fact, Zubairi Arabic does not exploit all the possible combinations of its phonemes. Different phonotactic parameters can be set to permit that certain types of consonant clusters are subject to constraints initially and medially. In addition, Zubairi consonants can be generally subsumed under the process of lengthening, i.e. geminate. consonant geminate can either be word-medially or wordfinally. Concerning syllable structure, Zubairi Arabic exhibits 10 syllabic patterns: /cv/, /cvv/, /ccvv/, /cvc/, / ccvc/, /cvcc/, /cvvc/, /ccvvc/and /ccvcc/.
Characterization of Pt-Pd/C Electrocatalyst for Methanol Oxidation in Alkaline Medium

The Pt-Pd/C electrocatalyst was synthesized on graphite substrate by the electrochemical codeposition technique. The physicochemical characterization of the catalyst was done by SEM, XRD, and EDX. The electrochemical characterization of the Pt-Pd/C catalyst for methanol electro-oxidation was studied over a range of NaOH and methanol concentrations using cyclic voltammetry, quasisteady-state polarization, chronoamperometry, and electrochemical impedance spectroscopy. The activity of methanol oxidation increased with pH due to better OH species coverage on the electrode surface. At methanol concentration (>1.0 M), there is no change in the oxidation peak current density because of excess methanol at the electrode surface and/or depletion of OH− at the electrode surface. The Pt-Pd/C catalyst shows good stability and the low value of Tafel slope and charge transfer resistance. The enhanced electrocatalytic activity of the electrodes is ascribed to the synergistic effect of higher electrochemical surface area, preferred OH− adsorption, and ad-atom contribution on the alloyed surface.
Renewable Energy Policy Development in Hawai ' i TARUI

This presentation reviews the development of recent renewable energy policy in Hawaii. It aims at identifying factors that influence the effectiveness of these policies in terms of energy availability and prices, energy security, and greenhouse gas reduction potential in the region. The State of Hawaii has a unique energy situation relative to the mainland United States. In 2008, close to 70% of electricity in the United States came from the combustion of coal and natural gas. In contrast, the State of Hawaii supplies more than 90% of its electricity by combusting imported petroleum. Given the local policy makers' and the general public's concerns about such high oil import dependence, the State adopted Hawaii Clean Energy Initiative (HCEI, 2008). HCEI aims to achieve 70% clean energy by 2030 with 30% from efficiency measures and 40% coming from locally generated renewable sources. Subsequently, a few policies to enhance clean energy development have been implemented (feed-in tariff, revenue decoupling, net metering). However, few in-depth studies analyze the effectiveness of such policies. Drawing on the experience in other US states and countries, the presentation will intend to assess the effectiveness of these new policies. Comparing the cases of Hawaii, Japan, and Okinawa in particular, could generate useful implications about the ongoing energy policy reforms in these regions. Given the rising oil prices and concerns about reliance on nuclear power after the Fukushima accident in 2011, Japan is increasing its reliance on oiland natural gas fired power generation on one hand and has been accelerating its policies to encourage renewable energy adoption (including feed-in tariffs in 2012) on the other. Documenting the details of political economy behind policy changes in both places tell us what factors promoted renewable energy policy. By assessing the effectiveness of the newly adopted policies, we will have a better idea about ·how renewable energy policy could be improved to allow more efficient energy transition that strikes an optimal balance between energy security and effectiveness in addressing climate change concerns.

Quantization of a Poisson structure on products of principal affine spaces

We construct a deformation quantization of a Poisson structure on products of principal affine spaces of a complex semisimple Lie group G and as a result, obtain a quantization of homogeneous coordinate rings of flat Poisson connections on ample line bundles over products of flag varieties of G, equipped with the Poisson structure studied by the author and Lu. We define the notion of a strongly coisotropic subalgebra in a Hopf algebra, and explain how strong coisotropicity guarantees that any homogeneous coordinate ring of a homogeneous space of a Poisson Lie group can be quantized in the sense of Ciccoli, Fioresi, and Gavarini.
Investigation of Ferroresonance Mitigation Techniques in Voltage Transformer Using ATP-EMTP Simulation

Ferroresonance is a complex nonlinear electrical phenomenon that can cause dielectric and thermal problems for electrical equipment. Electrical systems with ferroresonant behavior are nonlinear dynamical systems. The ferroresonance phenomenon may take place when the core of an inductive device becomes saturated, and its current flux characteristic becomes nonlinear. While in the case of a linear resonant circuit the resonance frequency is well defined, in the case of a nonlinear circuit, the oscillations may exist at various frequencies, depending on many factors of the particular case. In this paper, ferroresonance phenomenon and its mitigation techniques in 33 kV/110 V voltage transformers (VT) were studied using ATP-EMTP simulation. Initial investigations were carried out for the VT failures occurred at one substation in Malaysia. Physical and burn characteristics of the failed VTs were studied. Simulation results show that ferroresonance cannot be proven to have occurred at the VT due to switching operations since one precondition, namely the critical capacitance, could not have been satisfied. However, in the event of a ferroresonance occurring, several mitigation techniques such as using load resistors, proper grounding sequence, reconfiguration of VT connection, and overcurrent and overvoltage protection can be implemented.
Two superconducting transitions in single-crystal La2-xBaxCuO4

We use spatially-resolved transport techniques to investigate the superconducting properties of single crystals La$_{2-x}$Ba$_x$CuO$_4$. We find a new superconducting transition temperature $T_{cs}$ associated with the ab-plane surface region which is considerably higher than the bulk $T_c$. The effect is pronounced in the region of charge carrier doping $x$ with strong spin-charge stripe correlations, reaching $T_{cs}=36$ K or 1.64$T_c$.
Contextual variables of open innovation paradigm in the business environment of Slovenian companies

This article addresses the current condition of Slovenian business environment and its support to open innovation. By carrying out qualitative empirical research, we investigate to what extent determinants from internal, narrower and broader external business environment influence open innovation in Slovenian companies . Several support mechanisms were established to create friendlier environment for open innovation. Our study indicates that if Slovenia wants to be successful on the long run, supportive environment cannot and should not be based solely on government financial support, but must also contain other elements that affect technological development, meaning: 1) organizational culture, values, reward system; 2) legislation; 3) tax and social contributions; 4) bureaucratic barriers; 5) human resources; and 6) favorable bank loans, bank guarantees, venture capital, etc. The paper concludes with implications for managers and policy makers, outlining several promising areas for future research.
3D Model Retrieval Using 3D-DFT Spectral and Cepstral Descriptors of Local Octants

Conventional 3D-DFT features proposed for 3D model retrieval tried to extract the spectral/cepstral features from the spectrum/cepstrum of the 3D model, without considering the local properties of a 3D model. In this paper, local 3D-DFT spectral descriptor as well as local 3D-DFT cepstral descriptor will be proposed for 3D model retrieval. First, the set of voxels covering the surface of a 3D model is divided into 8 octants. 3D-DFT spectral descriptors and 3D-DFT cepstral descriptors are extracted from each octant and combined to form the local 3D-DFT spectral descriptor and local 3D-DFT cepstral descriptor. Experiments conducted on the Princeton Shape Benchmark (PSB) database have shown that the proposed local 3D-DFT descriptors outperform other 3D-DFT descriptors.
Paleotemperature History of the Cenozoic and the Initiation of Antarctic Glaciation: Oxygen and Carbon Isotope Analyses in DSDP Sites 277, 279 and 281

An oxygen and carbon isotopic history based on analyses of benthonic and planktonic foraminifera in three overlapping subantarctic sections is presented for the last 55 m.y. with a sampling interval ofless than 1 m.y. Surface temperature at Site 277, on the Campbell Plateau, was about 19°C in the early Eocene, about 13°C in the middle Eocene, about 11°C in the late Eocene, and about 7°C in the Oligocene. Declines in temperature appear to have been rather rapid and are separated by episodes of relative temperature stability. Bottom temperature at Site 277 was about 1°C below surface temperature in the Paleocene and about 2°C below surface temperature in the Oligocene. Site 279, on the Macquarie Ridge, records an early Miocene warming of over 2°C followed by a cooling and a second similar temperature rise in the middle Miocene. Bottom temperature at this somewhat deeper site was about 3°C below surface temperature and was probably as low as 4°C during part of the early Miocene. Comparisons between Sites 277 and 279 suggest that from the early Oligocene temperatures of deep water were low like the present day, implying that the mean annual temperature in high southern latitudes was near freezing by the beginning of the Oligocene (but certainly no earlier). From this time glaciers would have descended to sea level, and there would have been sea-ice production. If an ice sheet were present, it could not have been more than a small fraction of its present-day size. Site 281, on the South Tasman Rise, extends the record into the middle and late Miocene during which time the major East Antarctic ice sheet accumulated. A significant rise in surface temperature during the late Miocene did not cause the melting of this ice sheet, demonstrating that by this time it had already achieved its present invulnerability to climatic change. Since temperatures during much of the Miocene were significantly above any Pleistocene values, it is extremely unlikely that any climatic change in the geologically near future will significantly affect the stability of the East Antarctic ice sheet.
Using Experiments Design to Model Linear Firing Shrinkage of Triaxial Ceramic Bodies

In the development and manufacture stages of floor and wall ceramic tiles, firing shrinkage is basically determined by the combination of raw materials and frequently used as quality control parameters. This configures the ideal scenario to apply the techniques of experiments design, often used in various other areas, to model those properties of such ceramics bodies. In this work, ten formulations of three different raw materials, namely a clay mixture, potash feldspar and quartz (triaxial compositions) were selected and processed under conditions similar to those used in the ceramics industry. With the experimental results, a regression model was calculated, relating linear shrinkage with composition. After statistical analysis and verification experiments, the significance and validity of the model was confirmed. The regression model can then be used to select the best combination of those three raw materials to produce a ceramic body with specified properties.
Dépistage de pathologies par analyse de cris néonataux à l'aide de réseaux de neurones

Cette etude porte sur le depistage automatise de pathologies chez les nourrissons par analyse de leurs cris. Dans le cadre de ce projet, nous avons tente de realiser cette tâche a l’aide de techniques de classification par reseaux de neurones artificiels, entraines de facon supervisee. Les enregistrements provenaient de la base de donnees de l’Ecole de technologie superieure. Seuls les cris de nourrissons nes a terme et âges de 30 jours ou moins ont ete consideres. Les segments expiratoires des cris furent separes en echantillons de 400 millisecondes, puis ces echantillons furent subdivises en 8 trames de 50 millisecondes. Chaque echantillon etait represente par les coefficients du cepstre de frequences mel (MFCC) de ses trames. Nous avons evalue trois architectures de reseaux de neurones differentes : Les perceptrons multicouches (MLP), les reseaux convolutionnels (CNN) et les reseaux recurrents de type long short-term memory (LSTM). Nous avons entraine ces reseaux a reconnaitre diverses pathologies, notamment l’hyperbilirubinemie et la detresse respiratoire. La performance des classifieurs etait mesuree a l’aide de la validation croisee a k folds. Nous avons aussi reproduit, autant que possible, le dataset employe dans une autre etude, afin de permettre un comparaison equitable. Nous avons entraine et evalue notre systeme sur ce dataset. La comparaison des performances obtenues avec celles rapportees par l’etude de reference nous mene a conclure que notre approche a du potentiel, mais demeure pour l’instant inferieure a la leur. Pour finir, nous avons egalement demontre qu’une partition inadequate des donnees entre les ensembles d’entrainement et de validation pouvait produire une sous-estimation tres importante de l’erreur de generalisation reelle. Nous avons souleve des soupcons par rapport a la facon don't les donnees furent partitionnees dans plusieurs autres etudes sur la reconnaissance automatisee de pathologies chez les nourrissons par analyse de leurs cris.
Two-Area Load Frequency Control Using Ip Controller Tuned Based on Simulated Annealing

In this paper an optimal load frequency controller for two area interconnected power system is presented to quench the deviations in frequency and tie line power due to different load disturbances. In classical LFC problems, PI type controllers are used to control of system. But due to some disadvantages of the PI type controllers, the researches are toward finding a better control scheme. Although many different advanced method have been carried out to LFC problem, but the industries are willing to use simple PI controllers. In this scope, this paper presents IP type controller for LFC problem. The parameters of the proposed IP controller are tuned using Simulated Annealing (SA) method. A two-area electric power system with a wide range of parametric uncertainties is given to illustrate the proposed method. To show effectiveness of the proposed method and also comparison purposes, a PI type controller optimized by SA is also designed. The simulation results visibly show the validity of IP controller in comparison with PI controller.
Giving Requisite Variety to Strategic and Implementation Processes: Theory and Practice 1

Fundamental disagreements are inherent in the variety of viewpoints, and often coercive nature of relationships, contained within an organisation. In this paper I explain how differences in purpose can be handled successfully using approaches to complexity which take forward ideas developed since the 1950s in organisational cybernetics [1][2][3][4]. These methods complement the powerful complexity ideas derived from work focused on more unitary biological systems [5][6]. In Part 1, I work the requirements for individual and organisational survival and for participation leading to effective performance. I explain why managing differences in purposes in an increasingly interdependent world depends on finding organisational structures which balance the interests of autonomous individuals with those of the global social systems in which they participate. Design criteria are identified for optimising strategic and implementation processes and forging cohesive and effective organisational operations. Part 2 introduces through examples a methodology for undertaking related organisational transformations. This methodology has resulted in new strategic and implementation processes through the design of organisational structures which establish novel forms of co-operative relationships based on trust and self-organising autonomy.
