Study Regarding Effectiveness of Some Plant Extracts and Different Pesticides against an Erwinia Amylovora (Burrill.) Winslow et al. Strain Isolated from Quince

Study Regarding Effectiveness of Some Plant Extracts and Different Pesticides against an Erwinia Amylovora (Burrill.) Winslow et al. Strain Isolated from Quince The interest in management fire blight prevention and control increased considerably in last years due to pathogen spread almost throughout the country. The objective of this paper focuses on testing of some plant extracts such as Salvia officinalis, Thymus serpyllum, Pelargonium odoratissimum, Hedera helix, Ocimum basilicum, Levisticum officinale, Tagetes patula, Galium verum and different pesticides against an Erwinia amylovora strain isolated from quince dameged samples. In this study, the biological material was represented by quince shoots, harvested from pomological collection of "Vasile Adamachi" farm, which belongs to University of Agricultural Science and Veterinary Medicine Iaşi. The research were performed in the Phytopathology laboratory. Following the experiment performed note that among the eight plant extracts a good antibacterial activity has Pelargonium odoratissimum, Ocimum basilicum and Salvia officinalis and of the three pesticides, Alcupral 50 PU. Contrary to expectations worst results were obtained after testing Aliette 80 WG and Hedera helix products. The results were estimated statisticaly, by performing ANOVA test.

Spawning overlap of anchovy and sardine in the western North Pacific

Spatial and temporal spawning overlaps in Japanese anchovy Engraulis japonicus and sardine Sardinops melanostictus were examined using a long-term data set (1978 to 2004) of monthly egg and larval surveys (total of 102 613 vertical tow samples) off the Pacific coast of Japan. Egg abun- dance was estimated in 15' latitude × 15' longitude squares, and spawning area was calculated by summing areas of squares positive for egg occurrence. Both species had offshore expansion (inshore contraction) of spawning grounds with protracted (shortened) spawning periods during high- (low-) biomass phases. Although anchovy and sardine had different peak spawning periods (April to July and February to March, respectively), their spawnings were coincident from February to June in coastal waters. For anchovy, annual overlapping spawning area percentages of total spawning area and egg abundances in overlapping areas as percentages of total egg abundances were consistently low (6.4 to 30.6% and 7.2 to 39.9%, respectively). In contrast, for sardine these percentages were con- sistently high and notably increased as population size decreased (21.1 to 80.8% and 1.4 to 86.9%, respectively). Averaged over 5 yr (2000 to 2004), 68.5% of the total area of sardine spawning grounds overlapped with anchovy spawning grounds, and 61.8% of annual sardine egg abundance was produced in spawning grounds that overlapped with anchovy. Thus, Japanese sardine population recovery is likely more difficult than Japanese anchovy population recovery (when interspecific interavtions occur).
Influence of curd particles washing on the composition of curd made of milk in which co aggregates were formed

The composition of curd A and curd B was investigated as influenced by the technological process known as curd washing after removing 1/3 or 1/2 of whey and replacing by the same volume of water at the drying temperatures of 42oC and 45oC, respectively. Milk used for experiments was heat-treated at 87oC/10 min, during which the chemical complex between casein and whey proteins (milk protein co aggregates) was formed. It is shown that the applied drying temperatures of 42oC (curd A) and 45oC (curd B) do not have significant influence on the curd composition. The curd A and B gained without washing of the curd had 50.91% and 50.60% of moisture, respectively. If the curd washing process is applied after removing 1/3 of whey, the resulting curd has higher moisture content, 52.27% and 52.63%, respectively for the curd A and B. The highest moisture content in the curd is noted in the curd gained when 1/2 of whey is replaced by water during washing treatment. The same tendency is noted for the moisture in fat- free basis (MFFB), the parameter used for cheese classification. Also, it is observed that fat, protein and ash content are lower in the curd A and B when the curd washing process is applied than in the curd produced without the curd washing process. However, regardless of the increased moisture content of the curd gained by washing process, it is possible (even from heat-treated milk in which coaggreagates are formed) to achieve the average MFFB typical for semi-hard cheeses of Dutch type, by further technological processes such as molding, pressing, salting and ripening.
Probabilistic nonparametric model of impedance matrices

Economic and legal pressures on the structural engineers force them to consider uncertainty in the domains interacting, through boundary impedances, with their design structure. A probabilistic model of this impedance is constructed around a mean hidden state variables model using a nonparametric method. This mean model is constructed using only deterministic tools. The methodology is applied to the design of a gas tank on a layered soil.
Identifying Clay-construction Buildings in a Norfolk Market Town

SUMMARY Earth buildings form an important part of the built heritage in many places. This is no less true than in East Anglia, where there remains a heritage of those buildings built from timber frame with wattle and daub panels and those built from clay-lump. Through a combination of a lack of identification and a lack of understanding on the part of both built environment professionals and builders, this heritage is being irretrievably destroyed. There is a need for historic clay buildings to be identified and recorded. Once such buildings have been identified, both built environment professionals and builders need to be given the knowledge and equipped with the skills to treat them in an appropriate manner. The market town of Diss in Norfolk has a history of clay construction. In particular, parts of the town have a large number of clay-lump buildings. Therefore, Diss is a suitable town for the identification and recording of such buildings and for the dissemination of skills and knowledge. A small group of property professionals was set the task of identifying and recording buildings. Collected data were entered into a database that became the definitive one used by local authorities and others. The survey succeeded in developing a database of clay buildings in Diss. Knowledge was disseminated to both property professionals and builders. However, some questions of validity arose from inconsistencies in the collection and recording of data. Nevertheless, with refinement, the exercise provides a template for the collection and recording of data with respect to historic clay buildings in other towns and villages throughout East Anglia.
Reconcilable Differences: Momentum Trading By Institutions

A growing literature evaluates the relation between lag returns and demand by institutional investors. Given that lag returns and institutional ownership are directly observable, it is surprising that previous tests yield dramatically different conclusions. This study examines differences across studies and finds that four factors account for these discrepancies: (1) value-weighting versus equal-weighting across stocks, (2) averaging versus aggregating over managers, (3) disagreement in the signs of measures of institutional demand, and (4) correlation between current capitalization and both lag returns and measures of institutional demand. Controlling for these factors, the results across different methods are remarkably uniform.
Testing a Coupled Global-limited-area Data Assimilation System Using Observations from the 2004 Pacific Typhoon Season

Testing a Coupled Global-limited-area Data Assimilation System Using Observations from the 2004 Pacific Typhoon Season. (August 2011) Christina R. Holt, B.S., University of South Alabama Chair of Advisory Committee: Dr. Istvan Szunyogh Tropical cyclone (TC) track and intensity forecasts have improved in recent years due to increased model resolution, improved data assimilation, and the rapid increase in the number of routinely assimilated observations over oceans. The data assimilation approach that has received the most attention in recent years is Ensemble Kalman Filtering (EnKF). The most attractive feature of the EnKF is that it uses a fully flowdependent estimate of the error statistics, which can have important benefits for the analysis of rapidly developing TCs. We implemented the Local Ensemble Transform Kalman Filter algorithm, a variation of the EnKF, on a reduced-resolution version of the National Centers for Environmental Prediction (NCEP) Global Forecast System (GFS) model and the NCEP Regional Spectral Model (RSM) to build a coupled global-limited area analysis/forecast system. This has been the first time, to our knowledge, that such a system is used for the analysis and forecast of tropical cyclones. We used data from summer 2004 to study eight tropical cyclones in the Northwest Pacific.
Flavonoids are a group of polyphenolic compounds, diverse in chemical structure and characteristics .they occur naturally in fruits, vegetables, nuts, seeds, flowers, bark and an integral part of human diet

1-Introduction 1.1-General approach Flavonoids are a group of polyphenolic compounds, diverse in chemical structure and characteristics . they occur naturally in fruits, vegetables, nuts, seeds, flowers, bark and an integral part of human diet . They have been reported to exhibit a wide range of biological effects. Including antibacterial, antiviral , anti-inflammatory, antiallergic 1, 4, 5, and vasodilatory action. The term flavonids is generally used to describe a broad collection of natural products that include C6-C3-C6 backbones ,it’s nomenclature depending on the position of the linkage of aromatic ring to benzopyrano (chromano)moiety . This group of natural products may be divided in to four classes : the flavonoids(2-phenylbenzopyrans) 1, isoflavonoids(3benzopyrans) 2,neoflavonoids(4-benzopyrans) 3, and minor flavonoids. The first three classes usually share a common chalcone precursor and there are biogenetically and structurally related.
The effects of cowpox virus on survival in natural rodent populations: increases and decreases

Summary 1 The effect of cowpox virus on survival in two rodent hosts was investigated using nearly 4 years of longitudinal data from two sites. 2 We investigated whether an individual's probability of infection influenced the probability of surviving the next month. We also investigated the effect at the population level, examining whether, in addition to seasonal effects, changes in cowpox prevalence explained further temporal variation in survival rates. 3 In bank voles, but not wood mice, individuals with high probabilities of infection survived better than uninfected animals. 4 At the level of the population, the effect of infection on survival varied through the year in both species. Survival rates in late summer increased with cowpox prevalence, whilst survival rates in winter decreased with cowpox prevalence. 5 We discuss why parasites such as cowpox virus may increase or decrease host survival and why the effect may depend on the time of year.

Revisiting insurance capital structure, risk-taking behaviour and performance between 1995 – 2002

This paper examines the effect of capital structure and the moderation effect of risk-taking behaviour of insurance firms on performance of insurers in Nigeria from 1995 to 2002. This study became necessary as literatures in this area and regime are scarce. Secondary data from financial reports of each insurance firm were used. Descriptive statistics were used to describe the characteristics of the data while a two-stage estimation procedure of the fixed effect and random effect models were used to test the hypothetical framework of the study. Result shows that insurance capital structure (measured by equity ratio) had an insignificant negative effect on insurance performance while it had a significant positive effect on insurance performance if measured by technical provision ratios. On average, risk taking behaviour moderates the relationship between technical provision ratio and insurance performance. This study focused on capital structure and moderation effect of risk on performance of insurers in non risk-based capital era. Further study on risk-based capital era will provide more on performance of insurers before and after the implementation of risk-base capital requirement. These findings provide important insight to managers and regulators and investors by fostering more understanding of how to manipulate insurance capital and which source of fund should be used to embark on risky investment to attain superior performance. This investigation adds to literature on insurance capital structure, regulation and risk management and insurance performance in Nigeria.
The concept of transition system

The term ‘transition system’ describes features of a country’s institutional arrangements which shape young people’s education–work transitions. It explains why national differences in transition processes and outcomes persist despite apparent pressures for convergence. This paper asks how the concept of transition system has been conceptualised and operationalised by researchers, especially quantitative researchers analysing comparative survey data. It uses a four‐level conceptual framework which is implicit in much of this research. Micro‐level transition processes and outcomes (Level 1) may be aggregated or summarised to show national transition patterns (Level 2), which may be explained in terms of dimensions of national institutional variation (Level 3) or typologies of transition systems (Level 4). Research into transition systems can boast of empirical, theoretical and policy‐related achievements, but it has been constrained by data limitations and theoretical eclecticism. It needs to develop theoretical frameworks to explain how transition systems themselves change and to move beyond a view of nation‐states as homogeneous and independent units of analysis.
Unsupervised aircraft trajectories clustering: a minimum entropy approach

Clustering is a common operation in statistics. When data considered are functional in nature, like curves, dedicated algorithms exist, mostly based on truncated expansions on Hilbert basis. When additional constraints are put on the curves, like in applications related to air traffic where operational considerations are to be taken into account, usual procedures are no longer applicable. A new approach based on entropy minimization and Lie group modeling is presented here, yielding an efficient unsupervised algorithm suitable for automated traffic analysis. It outputs cluster centroids with low curvature, making it a valuable tool in airspace design applications or route planning. Keywords–curve clustering; probability distribution estimation; functional statistics; minimum entropy; air traffic management. I. INTRODUCTION Clustering aircraft trajectories is an important problem in Air Traffic Management (ATM). It is a central question in the design of procedures at takeoff and landing, the so called sid-star (Standard Instrument Departure and Standard Terminal Arrival Routes). In such a case, one wants to minimize the noise and pollutants exposure of nearby residents while ensuring runway efficiency in terms of the number of aircraft managed per time unit. The same question arises with cruising aircraft, this time the mean flight path in each cluster being used to optimally design the airspace elements (sectors and airways). This information is also crucial in the context of future air traffic management systems where reference trajectories will be negotiated in advance so as to reduce congestion. A special instance of this problem is the automatic generation of safe and efficient trajectories, but in such a way that the resulting flight paths are still manageable by human operators. Clustering is a key component for such tools: major traffic flows must be organized in such a way that the overall pattern is not too far from the current organization, with aircraft flying along airways. The classification algorithm has thus not only to cluster similar trajectories but at the same time make them as close as possible to operational trajectories. In particular, straightness of the flight segments must be enforced, along with a global structure close to a graph with nodes corresponding to merging/splitting points and edges the airways.
PROBABILITY DENSITY FUNCTIONS IN BISTABLE KINASE ACTIVATION MODEL

We consider a kinase auto-activation model in which the number of activated kinases follows the timecontinuous Markov process. In the deterministic approximation the process is described by the single nonlinear ordinary differential equation, which may have two stable steady states. We found that for sufficiently large number of kinases, the stationary probability distribution given by the Markov process concentrates in the vicinity of the two stable steady states of the deterministic approximation. However, if the number of kinases diverges to the infinity (zero noise limit), the stationary probability distribution concentrates (generically) in only one of the two steady states.
Reliable and Energy-Efficient Data Gathering in Wireless Sensor Networks via Rateless Codes and Compressed Sensing

It is difficult for data gathering via a fixed code rate in wireless sensor networks (WSNs) to achieve reliable recovery. Compared with the fixed code rate, rateless codes can continuously send a code word to the sink node until the source node information is recovered. Thus, data gathering methods based on rateless codes are effective in achieving reliable data in the sink node. However, to achieve high reliability, a large amount of sensor data must be collected, and this greatly increases the energy consumption of sensor nodes and the storage space of the sink nodes. Fortunately, data gathering via compressed sensing (CS) can largely reduce the number of sensor data collected to further save energy consumption and storage space. This paper proposes a data gathering method via rateless codes and CS. The proposed method can not only achieve reliable recovery, but also save energy consumption of data collection and storage space of the sink nodes. The experimental results show that the proposed method can reduce energy consumption by about 40% and storage space by about 40% compared with the data gathering via LT codes, which are a typical rateless code.
An improved moist‐convective rotating shallow‐water model and its application to instabilities of hurricane‐like vortices

We show how the two‐layer moist‐convective rotating shallow‐water model (mcRSW), which proved to be a simple and robust tool for studying effects of moist convection for large‐scale atmospheric motions, can be improved. The improvement is achieved by including, in addition to the water vapour, precipitable water, and the effects of vaporization, entrainment, and precipitation, rendering the model cloud‐resolving. It is applied, as an illustration, to model the development of instabilities of tropical cyclone‐like vortices.
Compression Behavior of Zr-doped Nanoanatase

The compression behavior of Zr-doped nano anatase Ti0.90Zr0. 10O2 synthesized by the sol-gel method was studied using a diamond anvil cell (DAC) up to ~ 13 GPa. The compressibility parallel to the a axis decreases strongly at ~ 4 GPa and other structural parameters also change with pressure. The parameters of the third order Birch-Murnaghan equation of state were fitted to: V0 = 139.6(0) Å3, K0 = 213(9) GPa and K′ = 17.9(2). Ab initio electronic structure simulations indicate that the Zr atoms cluster in the crystal. The effects of chemical substitution as well as of microstructure, especially the crystallite size, on the mechanical properties are discussed.
Oral Tacrolimus in Patients with Ulcerative Colitis

Tacrolimus is a macrolide immunosuppressant that is structurally similar to rapamycin and has been found to have potent immunosuppressive properties, showing 10to 100-fold higher potency for inhibiting lymphocyte activation than cyclosporine A (CsA). Because less variability in absorption and serum levels is observed among patients treated with tacrolimus compared with those who receive oral CsA, tacrolimus has been suggested to be more easily and safely administered to patients with refractory ulcerative colitis (UC) than CsA. However, because oral tacrolimus has a slower onset of action than intravenous CsA and food intake is known to reduce tacrolimus serum trough levels due to its low absorption rate, the proper method for administration of oral tacrolimus has not been determined. Moreover, the long-term effects of oral tacrolimus also remain unclear. In this chapter, key issues regarding the use of oral tacrolimus in patients with UC are reviewed.
