Germinação in vitro e criopreservação de sementes de Zinnia elegans

Zinnia elegans Jacquim is a species of big cutting and ornamental potential, but its seeds have low germination percentage. This study aimed to establish a protocol for in vitro germination and water content for the cryopreservation of seeds. The length, width, thickness, and weight of one thousand seeds were determined. MS and WPM culture mediums, as well as the concentrations of gibberellic acid (GA3) were tested regarding in vitro culture. For cryopreservation, the seeds were subjected to drying on silica gel or laminar flow for different times. Then, the seeds were stored in liquid nitrogen (-196° C) for 24 hours. After this period, the seeds were thawed and inoculated into culture medium. The biometric results of seeds showed 8.6 mm average length, 4 mm width, and 0.9 mm thickness. The weight of one thousand seeds was 851 mg, characterizing them as small, lightweight, and easy to disperse. The use of MS medium with no addition of GA3 enhanced germination (67%). The initial moisture content of Z. elegans seeds was 9%. Seeds subjected up to 2 hours of drying in both treatments obtained 23% germination in silica gel and 19% in laminar flow. Z. elegans seeds may be desiccated by 4% moisture content and cryopreserved with no loss of germination potential.

Volcanic plume fingerprint in the groundwater of a persistently degassing basaltic volcano: Mt. Etna

Abstract The chemical composition of the groundwater at Mt. Etna was investigated in order to determine the extent to which the persistent plume affects the chemical composition of circulating waters. Samples from 31 springs and wells were collected during June and July 2014 and analyzed for their chemical compositions. The content of dissolved elements derives from the bulk deposition (wet and dry deposition) at the recharge areas as well as from the weathering of volcanic rocks during the infiltration and transport of groundwater. In its early phase, the chemical weathering of volcanic rocks and ashes is promoted by the acid rain that characterizes the area and subsequently by the huge amount of deep magmatic carbon dioxide (CO 2 ) coming up through the volcanic edifice and dissolving in the water. The high content of chlorine is mainly derived from interactions between the plume and rainwater, while the total alkalinity can be completely ascribed to the dissociation of carbonic acid (H 2 CO 3 ) after the hydration of CO 2 . The relative contributions of plume-derived elements/weathering and CO 2 -driven weathering has been computed for each element. In addition, the comparison between the chemical compositions of the bulk deposition and of groundwater provides a new understanding about the mobility of volatile elements. The proposed approach has revealed that the persistent plume strongly affects the chemical composition of groundwater at Mt. Etna and probably also at other volcanoes characterized by huge open-conduit degassing activity.
Extremely coherent mechanical oscillators and circuit cavity electro-optics

The quest for mechanical oscillators with ultralow dissipation is motivated by classical and quantum sensing and technology, and precision measurements. For decades, the most coherent mechanical oscillators were acoustic vibrations in kg-scale crystalline bars. Recently a paradigm shift has occurred. The combination of elastic strain engineering – a technique used in microelectronics – with phononic mode engineering has resulted in 1D nano-strings with a mechanical quality factor Q of 0.8 billion – the highest ever achieved at room temperature. Remarkably, these new techniques have major untapped potential, as they have only been applied to non-crystalline materials in 1D. We propose a new generation of strain-engineered crystalline and superconducting mechanical oscillators whose Q-factors are predicted to exceed 100 billion in up to 2 dimensions. We will seek to reach this theoretical limit, probe new dissipation mechanisms, and utilize these oscillators for quantum optomechanics in new regimes and achieve room temperature ground state cooling and ponderomotive squeezing. Likewise, we will apply these techniques to create highly coherent superconducting electromechanical devices at milli-Kelvin temperatures, enabling quantum-enhanced force sensing and 1 second decoherence times. Secondly, we will explore a fundamentally new method for measurement and manipulation of microwave fields with optical fields – the nascent field of circuit Cavity-Electro-Optics (cCEO). First recognized over a decade ago, it is possible with optical fields to cool, amplify or interferometrically read out microwaves. Yet to date this regime has remained in accessible due to insufficient coupling strength between the microwave and optical fields. We will overcome this challenge based on a new circuit architecture, allowing laser cooling and laser amplification of microwaves and electro-optical masing using optical backaction, and thereby opening an entirely new way to manipulate microwaves.
Investors' Behavioral Biases and the Nigerian Stock Market Returns (2002 - 2012)

The paper was intended to find other reasons, based on investors’ behavior that may impact on the performance of the Nigerian stock market. The objectives were in three-fold: to examine the extent of behavioral biases among stock market investors in Nigeria; to determine the level of returns in the period using the Nigerian Stock Exchange All share index; and to examine the effects of behavioral biases on stock market return in Nigeria. This study was motivated by the fundamental explanations given for the causes of the 2008 collapse of the Nigerian Stock Market. This paper adopted a primary data approach based on survey research design to investigate the effects of behavioral biases on stock market return in Nigeria. The paper also used secondary data from the Nigerian Stock Exchange and employed questionnaire as instrument and the technique of correlation with Pearson Product Moment Coefficient to analyze a survey of 110 randomly selected investors in Nigeria stock market. The study found strong evidence that behavioral biases existed but not very dominant in the Nigeria stock market because a weak negative relationship existed between behavioral biases and stock market returns in Nigeria. The paper concluded that being aware of behavioral biases in the Nigerian stock market was a crucial first step in ensuring that investment decisions were properly controlled to avoid any negative impacts on the individual investors and on the stock market; again, behavioral biases might be of relevant consideration in portfolio construction in order to moderate these biases. Key words : Behavioral, Biases, Investors, Portfolios, Stock Market, Return, All Share Index.

Large eddy simulations and rotational CARS/PIV/PLIF measurements of a lean premixed low swirl stabilized flame

Abstract This paper reports on numerical and experimental studies of a lean premixed low swirl stabilized methane/air flame. The burner is made up of a central perforated plate and an annular swirler. A premixed methane/air mixture at an equivalence ratio of 0.62 is injected to an ambient co-flow of air through the burner under atmospheric pressure and room temperature condition with a Reynolds number of 30,000. Stereoscopic Particle Image Velocimetry (PIV) and simultaneous OH/acetone Planar Laser Induced Fluorescence (PLIF) are used to characterize the flame front and the turbulence field downstream of the burner. The flame is stabilized in the low speed central region and in the inner shear-layer vortices, where ambient air dilution to the flame is found to eventually quench the reactions downstream. Rotational Coherent Anti-Stokes Raman Spectroscopy (RCARS) measurements are carried out to characterize the temperature field and the relative oxygen mole fraction field, which enables quantification of the air dilution to the flame. The experimental data provides a challenging test case for numerical simulation models owing to the stratification of the mixture and quenching of the flame. Large eddy simulations are carried out using a three-scalar level-set G-equation flamelet model, which is shown to capture the basic flame characteristics and quenching at the trailing edge of the flame.

New evidence of sea-level lowstands and paleoenvironment during MIS 6 and 4 in the Cantabrian coastal karst: the Cobiheru cave (North Iberia)

The geomorphological evolution of the Cobiheru Cave shows the influence of the non-carbonate coastal mountain ranges on coastal karst evolution, as well as the temporal distribution of the cold-adapted fauna sites in the Cantabrian Coast. Geomorphological observation and U/Th dating lead to the construction of an evolution model. The model comprises two episodes of cave deposition occurred at ca. 60–70 and 130–150 ka, linked to cold climate conditions, global sea-level lowstands and the erosion of alluvial fans that covered the karst. Moreover, the comparison between the Cobiheru record and some raised beaches identified in previous studies sets the beginning of the sea-level lowering in the Cantabrian Sea during the MIS 5-4 transition. Two palaeoenvironments are inferred based on finding Equus ferus and Elona quimperiana. A wet deciduous forest would have been developed on the emerged marine terrace of the Cobiheru Cave since at least the Middle Pleistocene, and an open landscape with scarce vegetation would have been present at ca. 65 ka. The erosional event identified in the Cobiheru Cave helps to understand the temporal distribution of cold-adapted mammals located in the Asturias region. The probable sites of cold-adapted fauna developed in caves and alluvial fans would have disappeared after 65 ka. Therefore, palaeontological and palaeoclimate research based on cold-adapted mammals suggests the occurrence of an hiatus in the palaeontological record prior to 50 ka.

Small-Scale Structures in Three-Dimensional Hydrodynamic and Magnetohydrodynamic Turbulence: Proceedings of a Workshop Held at Nice, France, 10-13 January 1995

Small-scale structures in turbulent flows appear as a subtle mixture of order and chaos that could play an important role in the energetics. The aim here is a better understanding of the similarities and differences between vortex and current dynamics, and of the influence of these structures on the statistical and transport properties of hydrodynamic and magnetohydrodynamic turbulence, with special concern for fusion plasmas, and solar or magnetospheric environments. Special emphasis is given to the intermittency at inertial scales and to the coherent structures at small scales. Magnetic reconnection and the dynamo effect are also discussed, together with the effect of stratification and inhomogeneity. The impact of hydrodynamic concepts on astro and geophysical observations are reviewed.
Gut microbiota-microglia interactions in neurodevelopment

Childhood psychiatric disorders are alarmingly common, yet current gold-standard treatments fall short in creating lasting, meaningful improvements for many individuals. To improve outcomes, it is imperative to enhance our understanding of pathways to disordered development. Recent advances in the study of microglia-neuron interactions and critical period signals suggest that disruption in the developmental timing of these neural events may contribute to early-onset psychopathology. However, the factors that modulate these signals have not been well-defined. The GutMIND project will test the hypothesis that complementary maturation of the microbiota and the brain during critical windows of development may be one contributing factor. For the first time, the (sex-specific) trajectory of the microbiota’s influence on behavioural and neural outcomes during early host development will be characterised in detail. This will generate testable hypotheses regarding potential mechanisms and thus potential treatments to ameliorate the effects of microbiota depletion during critical periods. Specifically, this will be achieved by experimentally testing 1) metabolite pathways that may contribute to the microbiota’s influence on microglia-neuron communication and 2) the mediating role of the microglia in microbial influences on behaviour. In line with the objectives of the MSCA fellowships, the research project has been designed to facilitate the applicant’s career development by providing advanced training in supportive host environments that will diversify her research competencies, foster her managerial and teaching skills, and strengthen her research profile and professional network. In the process, public, industry, and scientific audiences will be engaged in the outcomes of the action through a multi-pronged communication, dissemination, & exploitation strategy that will promote positive mental health development in the EU and beyond.
Amphibians, Affect and Agency: On the Production of Scientific Knowledge in the Anthropocene

The scientific community agrees that we are in the midst of a mass extinction event caused by human impacts on the environment. Amidst this alarming loss in biodiversity, conservation biology has emerged as the authoritative body of knowledge by which we come to understand mass extinction and what can be done to prevent it. Using evidence from a case study of scientific research done by conservation biologists on amphibian declines and extinctions, this paper argues that conservation biology exists in the tension between an extension and a subversion of a post-Enlightenment scientific rationality. Part I of this paper supports the claim that conservation biology is an extension of post-Enlightenment rationality that positions the conservation biologist as an agent in the continued mastery and control of nature. Part II of this paper supports a counter-narrative that conservation biology is a subversion of post-Enlightenment scientific rationality that instead positions the conservation biologist as a partner with and advocate for nature.
The Participation Loop: Helping Citizens to Get In

In this paper we will explore how to enhance the work of Open Street Map (OSM) mappers through the structuring of their contributions by calculating tasks. Tasks are a common way to break large jobs into smaller pieces. But in OSM the big 'mapping' job is not structured in any way. There is no task pool, or even anything similar. Using several different techniques and technologies, we will calculate well defined and assignable mapping tasks. With this approach, the community has more feedback over what is already done and what they need to do. Slowly, using such techniques, we engage these communities in the participation loop.
Efficient parallel architecture for implementation of the CMA adaptive antenna

AbstractThis paper presents an efficient parallel architecture for implementation of a constant modulus algorithm (CMA) adaptive array antenna. By inserting delay units into the original CMA, a novel delayed CMA (DCMA) that can significantly reduce the associated critical path is derived. Consequently, a pipelining architecture that supports parallel processing is introduced for implementation of the DCMA. In addition to the pipelining technique, a power-of-two multiplier is proposed for the DCMA leading to the efficient FPGA implementation. The effects of delays and finite word-length on the convergence property of CMA are investigated via simulations. Moreover, the synthesized results demonstrate that FPGA implementation of the proposed architecture using power-of-two arithmetic achieves 26.9% resource reduction in comparison with that of fixed-point arithmetic and operating clock frequency higher than 65 MHz. The implemented FPGA was tested to confirm that the designed architecture operates well for CMA.

The Impact of Multinational Companies on the Employment in Romania

Abstract The activities of multinational companies (MNCs) in the host country are considered in scientific literature an element that is stimulating economic growth. This is the reason authorities of former communist countries attempted to stimulate the entry of foreign direct investments (FDI). This paper will focus on the effects of MNCs presence in the host country, mainly on the employment rate. This issue is important because, beginning with the change of the political regime, Romania has undergone a transformation of its productive structures. These changes were often accompanied by the reorganization of large state enterprises, which were old and oversized. It led to the discharge of a large number of their employees. In these conditions can one ask to what extent MNCs played a role in creating new jobs in Romania? In order to answer this question, we used the results of our survey, which used as subjects the French multinational companies established in Romania.
