Potencial biofertilizante de bacterias diazótrofas aisladas de muestras de suelo rizosférico

Las bacterias promotoras del crecimiento vegetal son capaces de adaptarse, colonizar y persistir en la rizosfera de la planta, lo cual favorece su crecimiento y desarrollo. En este trabajo se aislaron 32 cepas nativas de bacterias diazotrofas, a partir de muestras de suelo rizosferico de diferentes cultivos, identificadas mediante los medios de cultivo tradicionales y el sistema BBL CRYSTAL. La identificacion bioquimica se realizo a traves de la reaccion en cadena de la polimerasa (PCR, del ingles Polymerase Chain Reaction). Nueve aislados se determinaron como Stenotrophomonas maltophilia y uno como Azotobacter vinelandii , de los cuales tres coincidieron en la identificacion bioquimica y la molecular. Se realizo un ensayo en invernadero para evaluar el efecto fertilizante en plantas de maiz, segun un diseno experimental de bloques al azar y nueve tratamientos, por triplicado: tratamiento 1: A. vinelandii ATCC 9046; tratamientos del 2 al 7 para los seis aislados; tratamiento 8 para fertilizacion quimica; y tratamiento 9 para suelo sin fertilizacion (testigo). Los aislados M8-10, M10-1 y M11-3, identificados como S. maltophilia por PCR, tuvieron mejores resultados en la emergencia de las plantas, el diametro del tallo y la longitud de las hojas y los tallos. Finalmente se determino que M10-1 mostro valores de emergencia y crecimiento de la planta por encima de la media y el limite superior, con respecto a los demas aislados y controles, lo cual lo convierte en un potencial biofertilizante.
Thermo-mechanical nonlinear vibration analysis of fluid-conveying structures subjected to different boundary conditions using Galerkin-Newton-Harmonic balancing method

The development of mathematical models for describing the dynamic behaviours of fluid conveying pipes, micro-pipes and nanotubes under the influence of some thermo-mechanical parameters results into nonlinear equations that are very difficult to solve analytically. In cases where the exact analytical solutions are presented either in implicit or explicit forms, high skills and rigorous mathematical analyses were employed. It is noted that such solutions do not provide general exact solutions. Inevitably, comparatively simple, flexible yet accurate and practicable solutions are required for the analyses of these structures. Therefore, in this study, approximate analytical solutions are provided to the nonlinear equations arising in flow-induced vibration of pipes, micro-pipes and nanotubes using Galerkin-Newton-Harmonic Method (GNHM). The developed approximate analytical solutions are shown to be valid for both small and large amplitude oscillations. The accuracies and explicitness of these solutions were examined in limiting cases to establish the suitability of the method.

Petrology and geochemistry of rocks from the basement of the Pechenga paleorift

The basement of the Early Proterozoic Pechenga paleorift was penetrated by the Kola Superdeep Borehole over a depth interval of 6842-12,261 m. The principal types of basement rocks are gneisses of trondhjemite-tonalite composition in association with amphibolites, gneisses containing aluminous minerals, and banded iron formation (BIF). It was demonstrated that the paleorift basement and rock associations exposed at the surface in the northwestern part of the Kola-Norwegian block are of similar age, composition of their protoliths, and correspond to the main types of sedimentary- volcanic and plutonic rocks of the Archean granite-greenstone terrane, which was broken up into separate segments in the Early Proterozoic. Rocks of the Pechenga Archean basement were aected by Proterozoic magmatism and metasomatism related to the rift development. The most intense Proterozoic processes in the Pechenga basement and its nearest surroundings were intrusion of numerous mafic-ultramafic bodies, retrograde metamorphism to the medium-low-temperature amphibolite and epidote amphibolite facies, synmetamorphic migmatization, and emplacement of postkinematic granite dikes. Most Proterozoic processes were determined to have been related to mantle sources. The overall amounts of Proterozoic material introduced into the Archean rocks penetrated by the lowermost part of the borehole plus the remobilized Archean crustal material were estimated at 30% ( 12-15% amphibolites, 3% granite veins, and 15% migmatized rocks).
Lateral and torsional vibrations of cable-guided hoisting system with eccentric load

Theoretical investigation of the lateral and torsional vibrations of the hoisting cage in the cable-guided hoisting system caused by the eccentric load and the flexibility of the guiding cable is presented in this paper. The assumed modes method (AMM) is adopted to discretize the hoisting cable and two guiding cables, then Lagrange equations of the first kind are used to derive the equations of motion, while the geometric relationships between the hoisting cage and the cables are accounted for by the Lagrangian multiplier. Considering all the geometric matching conditions are approximately linear, the differential algebraic equations (DAEs) are transformed to the ordinary differential equations (ODEs). The dynamic responses of the hoisting cage are calculated, and especially the lateral displacements of the guiding cable and the constraints forces at the interfaces are obtained. Preload plays a vital role in affecting the cage vibration, thus, the effects of the total preload and the tension difference are analyzed. The numerical results indicate increasing the total preload can decrease the vibration displacements, while the tension difference has little impact on the vibration but can obviously change the constraint forces. In addition, the vibration displacements are directly proportional to the eccentric load, but less sensitive to the hoisting mass.
Non-utilitarian Tourism Destination Positioning using Affective Images and Personality Traits

While utilitarian thinking no longer dominates current marketing academia and practice, the extant destination positioning literature has largely neglected tourists’ non-utilitarian consumption needs. This study addresses this academic lacuna by incorporating the constructs of ‘destination affective image’ and ‘destination brand personality’ into a non-utilitarian destination positioning case of Dalian as a marine city destination in the domestic leisure tourism market. A sequential process was used to develop valid measures of ‘destination affective image’ and ‘destination brand personality’ pertinent to a marine city travel context. Data were collected in Dalian and four close competitors in northern China. The key differentiating points identified from using each of the two constructs were used to formulate a suggested ‘un-utilitarian position’ for Dalian. Data confirmed the efficacy of the non-utilitarian destination positioning approach proposed.
Molecular Imprinting

* Jesika Rane, Dept. of Quality assurance, College of pharmacy, Sakegaon. Jalgaon, India. ABSTRACT This article gives the recent developments in molecular imprinting for proteins. Currently bio-macromolecules such as antibodies and enzymes are mainly employed for protein recognition purposes. However, such bio-macromolecules are sometimes difficult to find and/or produce, therefore, receptor-like synthetic materials such as protein-imprinted polymers have been intensively studied as substitutes for natural receptors. Recent advances in protein imprinting shown here demonstrate the possibility of this technique as a future technology of protein recognition. This review summarizes the previous and current literature regarding the analytical tools employed for characterization of synthesized MIPs. It is our expectation that this will facilitate researchers to plan their own sophisticated analytical pathway for characterization of MIPs in a more logical and structured fashion, and to begin to appreciate the limitations of the present approaches in this molecularly complex area.
MEASURING THE SHADOW ECONOMY WITH THE CURRENCY DEMAND APPROACH A REINTERPRETATION OF THE METHODOLOGY, WITH AN APPLICATION TO ITALY

We contribute to the debate on how to assess the size of the shadow economy by proposing a reinterpretation of the traditional Currency Demand Approach (CDA) a là Tanzi. In particular, we introduce three main innovations. First, we take a direct measure of cash transactions (the flow of cash withdrawn from bank accounts relative to total noncash payments) as the dependent variable in the money demand equation. This allows us to avoid using the Fisher equation, overcoming two severe critiques to the traditional CDA. Second, we include among covariates two distinct measures of ‘detected’ tax evasion, in place of the tax burden level. Finally, we control also for a new ‘criminal’ component of the shadow economy, considering money demand for illegal activities like drug dealing and prostitution. We propose an application of this ‘modified – CDA’ to a panel of 91 Italian provinces for the years 2005-2008. demand’ for cash payments due to tax evasion by using two measures of detected tax noncompliance, thus avoiding finding suitable proxies able to capture all the relevant causes of the phenomenon. Third, besides evasion, we identify a criminal component of the shadow economy, by introducing an appropriate determinant of the demand for money due to crime. We present an application of this ‘modified – CDA’ exploiting original data on monetary variables, tax evasion and reported illegal activities for the Italian Provinces over the period 2005-2008. Our results show an average value of the shadow economy due to evasion up to 16.5% of GDP, which is consistent with the recent estimates available from official statistical sources relying on microeconomic methods of measurement, but appears to be lower than the values obtained for Italy in the international literature (e.g., Schneider and Enste, 2000, 2002 and Schneider, 2010). We show that this discrepancy is likely to be due to the omission of criminal activities in the application of the traditional CDA. Not surprisingly, when the model accounts for shadow criminal transactions, our estimates of the shadow economy increase by about 11% of GDP. This evidence points out that, ignoring illegal activities, one could not only mistakenly attribute to evasion a part of the shadow economy due to criminal transactions – for which it is not possible to implement law enforcement policies to recover lost tax revenues –, but could also underestimate the total value of underground economy. the availability at a territorial level, we also provide estimates macro-areas. is an important step in the underground economy and size, because of marked North-South divide quality social Italy.
No . 729 Understanding the World Trade Collapse

RESUMÉ Understanding the world trade collapse The collapse in world trade volumes at the end of 2008 and beginning of 2009 was exceptional by historical standards. This paper shows that world demand (to which trade has become more responsive in recent decades) can explain most of the collapse in world trade, but that tight credit conditions have likely amplified the short-term trade response. Credit tightening likely accelerated the trade decline through trade finance constraints and its relatively larger impact on trade-intensive sectors. A portion of the trade decline remains unexplained, which may reflect a possible breakdown in global supply chains. Looking ahead, the pace of normalisation in financial conditions and the future evolution of global supply integration will affect the speed of recovery in trade and global output.

A Rare t(5;11)(q35;q13) Translocation in an Elderly Patient With Acute Myeloid Leukemia With Maturation: A Case Report

The t(5;11)(q35;q13) reciprocal translocation is a rare chromosomal abnormality that can arise in myeloid neoplasms, mainly in children and younger adults. Here, we report a case of acute myeloid leukemia with maturation, involving an 85-year-old, in which the tumor cells harbored the t(5;11)(q35;q13) chromosomal abnormality. We also address the diagnostic and immunophenotypic characteristics of acute myeloid leukemia involving t(5;11)(q35;q13), along with a review of the literature.
Shifting the Frontiers of Analog and Mixed-Signal Electronics

Nowadays, analog and mixed-signal (AMS) IC designs, mainly found in the frontends of large ICs, are highly dedicated, complex, and costly. They form a bottleneck in the communication with the outside world, determine an upper bound in quality, yield, and flexibility for the IC, and require a significant part of the power dissipation. Operating very close to physical limits, serious boundaries are faced. This paper relates, from a high-level point of view, these boundaries to the Shannon channel capacity and shows how the AMS circuitry forms a matching link in transforming the external analog signals, optimized for the communication medium, to the optimal on-chip signal representation, the digital one, for the IC medium. The signals in the AMS part itself are consequently not optimally matched to the IC medium. To further shift the frontiers of AMS design, a matching-driven design approach is crucial for AMS. Four levels will be addressed: technology-driven, states-driven, redundancy-driven, and nature-driven design. This is done based on an analysis of the various classes of AMS signals and their specific properties, seen from the angle of redundancy. This generic, but abstract way of looking at the design process will be substantiated with many specific examples.
The returns to education: a review of the empirical macro-economic literature

The idea of positive educational externalities is that the benefits of individually acquired education may not be restricted to the individual but might spill over to others as well, accruing at higher aggregation levels, in particular at the macro-economic one. We offer an extensive summary and a critical discussion of the empirical literature on the impact of human capital on macro- economic performance, with a particular focus on UK policy. Key findings include: (1) Taking the studies as a whole, there is compelling evidence that human capital increases productivity. Although there is an important theoretical distinction between the augmented neo-classical approach and the new growth theories, the empirical literature is still largely divided on whether the stock of education affects the long-run level or growth rate of the economy. A one-year increase in average education is found to raise the level of output per capita by between 3 and 6 percent according to augmented neo-classical specifications, while it would lead to an over 1 percentage point faster growth according to estimates from the new-growth theories. (2) Over the short-run planning horizon (4 years) the empirical estimates of the change in GDP for a given increase in the human capital stock are of similar orders of magnitude in the two approaches. (3) The impact of increases at different levels of edu-cation appear to depend on the level of a country's development, with tertiary/higher education being the most important for growth in OECD countries. (4) Education is found to yield additional indirect benefits to growth (in par-ticular, by stimulating physical capital investments and technological development and adoption). More preliminary evidence seems to indicate that type, quality and efficiency of education all matter for growth. The most pressing methodological problems are the measurement of human capital; systematic differences in the coefficient of education across countries (in particular between developing and developed countries) and reverse causality. We also make recommendations for future research priorities.
Facial Behaviors and Emotional Reactions in Consumer Research

Gauging emotional reactions is a cornerstone of consumer research. The most common way emotions are assessed is self-report. But self-report is notoriously unreliable, and affected by many factors that confound their interpretation. Facial expressions are objective markers of emotional states, and are well grounded in decades of research. Yet, the research documenting the potential utility of facial expressions of emotion as a biometric marker in consumer research is limited. This study addresses this gap, presenting descriptive analyses of the facial expressions of emotion produced in typical consumer research. Surprisingly, the most prevalent expressions produced were disgust and social smiles; smile of true enjoyment were relatively rare. Additionally, expressions were generally of low intensity and very short durations. These findings demonstrate the potential utility for using facial expressions of emotion as markers in consumer research, and suggest that the emotional landscapes of consumers may be different than what is commonly thought.
Improving the search efficiency of a covariance model for RNA homology search

In the RNA gene finding area, the covariance model, a probabilistic model based on contextfree grammar, provides excellent accuracy. However, high computational complexity has limited its usefulness. This research improves the covariance model’s search efficiency by building combined models for a group of different RNA families, which is selected using a hierarchical clustering strategy. Two approaches for building combined models are proposed and implemented. The first approach uses a greedy algorithm to select base pairs from each original family’s secondary structure to form a new structure from which a combined covariance model is then built. The second approach constructs a series of combined partial covariance models which are built from the stem loop structural elements and are less complicated than complete models. Experimental results suggest that for most RNA gene families investigated, our combination search method successfully provides run time improvement with acceptable accuracy. Although there still exist limitations such as recall loss for a few RNA gene families, this novel combination approach has implications for future studies of reducing covariance model’s search complexity.
When good neighbours become good friends: observing small scale structures in fish aggregations using multibeam sonar

Converging results in different scientific fields (behavioural ecology, fisheries biology, acoustic tagging, fisheries acoustics, behavioural modelling) suggest the existence of "micro-groups" inside fish schools. These would comprise a few (5-10) fish maintaining contact during a period long enough to allow individuals to recognise each other. It is hypothesised that they would prefer to share the space with familiar rather than anonymous conspecifics. To evaluate whether acoustic methods could be used to recognise "micro-structures" inside fish schools and help test the "micro-group" hypothesis we analysed acoustic data from anchovy schools off Peru, and gadoids in the North Sea. Data collection used a multibeam sonar (Reson SeaBat 6012). In the Peruvian case study, the sonar was mounted set horizontally on a drifting research vessel and the internal structure of the schools of anchovies was analysed, although individual fish could not be discriminated. In the North Sea case study, the sonar was orientated vertically above a demersal trawl to allow observation of individual fish entering the trawl. Geostatistical analyses were used to evaluate the existence of small spatial structures in anchovy schools. In these schools, "micro-structures" with a scale as small as 0.5 m were observed acoustically. For the gadoids nearest neighbour distance (NDD) measurements were carried out, suggesting that the fish aggregated in small groups (2 to 25 individuals, with an average of 3.7 fish per group) in the trawl catches. The perspectives and limitations of these results are discussed.
Twist in a polar blowout jet

It is well known that some coronal jets exhibit helical structures and untwisting. We attempt to inspect the origin of twist in a blowout jet. By means of multi-wavelength and multi-angle observations from Solar Dynamics Observatory (SDO) and Solar Terrestrial Relations Observatory-Ahead (STEREO-A), we firstly report a polar untwisting jet that is a blowout jet which leads to a jet-like coronal mass ejection. From the viewpoint of SDO, the jet shows clear untwisting behavior and two jet-spires. However, from the viewpoint of STEREO-A the jet actually comes from the whiplike prominence eruption and is followed by a white-light jet. Our observations indicate that twist in blowout jets may result from the erupting mini-prominences/mini-filaments in the jet base.
Bayesian non‐parametric inference for species variety with a two‐parameter Poisson–Dirichlet process prior

Summary. A Bayesian non‐parametric methodology has been recently proposed to deal with the issue of prediction within species sampling problems. Such problems concern the evaluation, conditional on a sample of size n, of the species variety featured by an additional sample of size m. Genomic applications pose the additional challenge of having to deal with large values of both n and m. In such a case the computation of the Bayesian non‐parametric estimators is cumbersome and prevents their implementation. We focus on the two‐parameter Poisson–Dirichlet model and provide completely explicit expressions for the corresponding estimators, which can be easily evaluated for any sizes of n and m. We also study the asymptotic behaviour of the number of new species conditionally on the observed sample: such an asymptotic result, combined with a suitable simulation scheme, allows us to derive asymptotic highest posterior density intervals for the estimates of interest. Finally, we illustrate the implementation of the proposed methodology by the analysis of five expressed sequence tags data sets.

From Supreme Court to Shopfloor: Mandatory Arbitration and the Reconfiguration of Workplace Dispute Resolution

Excerpt] In a series of court battles during the 1990s, employers successfully defended the use of mandatory employment arbitration against challenges that the procedures inherently undermined the statutory rights of employees. Efforts to introduce legislation in Congress aimed at reversing the Gilmer decision were unsuccessful. In 2001, the Supreme Court reaffirmed its acceptance of mandatory arbitration to resolve employment disputes in Circuit City Stores, Inc. v. Adams. However, some courts have been willing to strike down arbitration procedures that contain particularly egregious violations of due process. For example, courts have refused to enforce arbitration agreements that restrict employee damage awards, require employees to pay half of the arbitration costs (which may amount to thousands of dollars or that impose one-sided obligations to arbitrate), or that allow the employer access to the courts while the employee is forced to arbitrate. In the vast majority of cases, however, the courts have enforced mandatory arbitration agreements where the procedures do not include any egregiously one-sided provisions.
