Yield and Nutritional Value of Swiss Chard Grown for Summer and Autumn Harvest

Seeds of 5 Swiss chard cultivars were sown on 20 April or 15 July, and single harvest of leaf rosettes was conducted on early July or half of October, respectively. Results of the study indicate the possibility of growing the Swiss chard both in spring and autumn term, but yield of leaves obtained in the spring was double as high as in the autumn cultivation. Among tested cultivars Green White Ribbed and Bresanne provided the highest, while Vulcan the lowest yield in spring growing. However, the choice of cultivar had not a significant meaning in autumn season cultivation. Spring season culture caused a significant reduction of nitrates accumulation and was preferable for the content of P, while autumn term for dry matter, K and Ca in both parts of leaves, vitamin C in leaf blades, and Mg in petioles. Irrespective of the term of growing and cultivar, leaf blades contained higher level of dry matter and Mg, while leaf petioles - nitrates, potassium and calcium.
" Pasteurella piscicida ": aspectos taxonómicos, serológicos y de patogenicidad

En este trabajo hemos caracterizado y determinado los factores de virulencia y los aspectos epizootiologicos de " Pasteurella piscicida ", agente etiologico de la pasteurelosis. Esta enfermedad causa importantes perdidas economicas en acuicultura marina. P. piscicida constituye un grupo homogeneo desde el punto de vista fenotipico y serologico, pero presenta heterogeneidad a nivel de patrones de RNA ribosomico. Los ensayos de virulencia "in vivo" demostraron que las cepas no patogenas no poseen especificidad de huesped. El estudio de los mecanismos de patogenicidad revelo que " P. piscicida " posee sistemas de alta afinidad para la captacion de hierro y toxinas con accion fosfolipasa y citotoxica que estan implicados en la patogenesis de la pasteurelosis. Las vacunas enriquecidas con los productos extracelulares confieren niveles de proteccion adecuados y el tamano de los peces es un factor importante a tener en cuenta a la hora de realizar los programas de vacunacion. " P. piscicida " permanece viable en el medio marino durante periodos de tiempo de al menos un mes y la epidermis puede ser una de las vias de entrada en el interior del pez.
Uma extensão do método bem aplicada ao projeto de rotores hidrocinéticos de eixo horizontal

Neste trabalho apresenta-se um modelo matemático correspondente a uma extensão da teoria clássica do momento do elemento de pá para o dimensionamento de rotores hidrocinéticos de fluxo livre, com operação estendida a razões de velocidade menores que 2. Nesse caso, foi considerada a influência da esteira sobre o plano do rotor na sua forma mais geral. Tal influência mostra-se considerável quando a razão de velocidade é pequena, justificando a necessidade de formulações que preveem os efeitos da esteira sobre o rotor. Os resultados obtidos a partir dautilização do modelo proposto são comparados com o modelo BEM clássico e com o utilizado pelo NationalRenewable Energy Laboratory– NREL, sendo satisfatórios por apresentarem boa eficiência para baixas razões de velocidade de escoamento, comuns nos rios amazônicos.

Filtering and Likelihood Estimation of Latent Factor Jump-Diffusions with an Application to Stochastic Volatility Models

In this article we use a partial integral-differential approach to construct and extend a non-linear filter to include jump components in the system state. We employ the enhanced filter to estimate the latent state of multivariate parametric jump-diffusions. The devised procedure is flexible and can be applied to non-affine diffusions as well as to state dependent jump intensities and jump size distributions. The particular design of the system state can also provide an estimate of the jump times and sizes. With the same approch by which the filter has been devised, we implement an approximate likelihood for the parameter estimation of models of the jump-diffusion class. In the development of the estimation function, we take particular care in designing a simplified algorithm for computing. The likelihood function is then characterised in the application to stochastic volatility models with jumps. In the empirical section we validate the proposed approach via Monte Carlo experiments. We deal with the volatility as an intrinsic latent factor, which is partially observable through the integrated variance, a new system state component that is introduced to increase the filtered information content, allowing a closer tracking of the latent volatility factor. Further, we analyse the structure of the measurement error, particularly in relation to the presence of jumps in the system. In connection to this, we detect and address an issue arising in the update equation, improving the system state estimate.
Dynamical matter-parity breaking and gravitino dark matter

Scenarios where gravitinos with GeV masses makeup dark matter are known to be in tension with high reheating temperatures, as required by e.g. thermal leptogenesis. This tension comes from the longevity of the NLSPs (next-to-lightest supersymmetric particle), which can destroy the successful predictions of the standard primordial nucleosynthesis. However, a small violation of matter parity can open new decay channels for the NLSP, avoiding the BBN (standard primordial nucleosynthesis) problems, while being compatible with experimental cosmic-ray constraints. In this paper, we propose a model where matter parity, which we assume to be embedded in the U(1){sub B-L} gauge symmetry, is broken dynamically in a hidden sector at low-scales. This can naturally explain the smallness of the matter parity breaking in the visible sector. We discuss the dynamics of the corresponding pseudo Nambu-Goldstone modes of B-L breaking in the hidden sector, and we comment on typical cosmic-ray and collider signatures in our model.
Present and future status of flexible spectral imaging color enhancement and blue laser imaging technology

The usefulness of flexible spectral imaging color enhancement (FICE) has been reported for evaluating the esophagus, stomach, and small and large intestine. Higher contrast is shown between cancer and the surrounding mucosa in the esophagus and stomach and may facilitate the detection of gastric cancers missed by white light imaging alone. The surface patterns of gastric mucosa are clearly visualized in non‐malignant areas but are irregular and blurred in malignant areas, leading to clear demarcation. Capsule endoscopy with FICE detects angiodysplasia and erosions of the small intestine. The surface and vascular pattern with FICE is useful for the differential diagnosis of colorectal polyps. However, FICE remains somewhat poor at visualizing mucosal microvasculature on a tumor surface. Narrow‐band imaging (NBI) is dark in observing whole gastric mucosa and poor at visualizing mucosal microstructure. Blue laser imaging (BLI) has the potential to resolve these limitations. Narrow‐band laserlight combined with white light shows irregular microvessels on both differentiated and undifferentiated gastric cancer similar to those using NBI. In addition, irregular surface patterns including minute white zones are clearly seen on the uneven surface of differentiated lesions, resulting in exclusion of undifferentiated lesions. Using both distant and close‐up views, a high contrast between green intestinal metaplasia and brown gastric cancer may lead to early detection of gastric cancers and determination of a demarcation line. BLI produces high‐contrast images in esophageal cancer with clear vision of intrapapillary capillary loops and also predicts the histopathological diagnosis and depth of invasion in colorectal neoplasms.
Modèles de la théorie des types donnés par traduction de programme

Dans cet article, nous presentons quelques modeles du calcul des constructions avec univers (CCω) donnes par des traductions de programme. De tels modeles peuvent etre vus comme la compilation d'une theorie des types compliquee vers une theorie des types plus simple. Nous les utilisons pour montrer simplement que certains axiomes ne sont pas derivables dans CCω : l'extensionnalite fonctionnelle, l'extensionnalite propositionnelle et le fait que la bissimilarite implique l'egalite pour les streams. Ces modeles permettent egalement d'a jouter de nouveaux operateurs dans la theorie source. Nous prendrons l'exemple du pattern matching sur un univers. Les traductions de programme ont l'avantage sur les autres modeles de pouvoir etre instrumentees sous forme de plug-ins d'un assistant de preuve (nous utiliserons Coq), ce qui permet d'ajouter de nouveaux axiomes a la volee, tout en preservant la coherence de la theorie.
Cytokines in neovascular age-related macular degeneration: fundamentals of targeted combination therapy

The neovascular form of age-related macular degeneration (AMD), called wet-AMD or choroidal neovascularisation, begins with damage to the outer retinal cells and retinal pigment epithelium (RPE), which elicits a cascade of inflammatory and angiogenic responses leading to neovascularisation under the macula. Studies showed that oxidative damage, chronic inflammation of the RPE and complement misregulation work at different steps of this disease. After established neovascularisation, several pro- and antiangiogenic agents start to play an important role. Vascular endothelial growth factors (VEGFs) are the most specific and potent regulators of angiogenesis, which are inhibited by intravitreal injections of ranibizumab, bevacizumab, VEGF Trap, pegaptanib sodium and other agents under investigation. Pigment epithelium-derived factor, on the other hand, shows neuroprotective and antiangiogenic activities. Hepatocyte growth factor (HGF) has a mitogenic effect on a wide range of epithelial and endothelial cells, and it is inhibited by an anti-HGF monoclonal antibody. Platelet-derived growth factor is a potent chemoattractant and mitogen for both fibroblasts and retinal RPE cells, which has been inhibited experimentally by VEGF Trap and human anti-platelet-derived growth factor-D monoclonal antibody. Fibroblast growth factor-2 has pleiotropic effects in different cell and organ systems, and it is blocked by anti-FGF antibodies, with a greater benefit regarding antiangiogenesis when combined treatment with anti-VEGF is performed. Tumour necrosis factor alpha is expressed in the retina and the choroid, and its blockade in choroidal neovascularisation includes the use of monoclonals such as infliximab. This paper reviews the most important cytokines involved in the pathogenesis of wet-AMD, with emphasis on potential combined therapies for disease control.
Buffering Fuzzy Maps in GIS

In this paper, we show how standard GIS operations like the complement, union, intersection, and buffering of maps can be made more flexible by using fuzzy set theory. In particular, we present a variety of algorithms for operations on fuzzy raster maps, focusing on buffer operations for such maps. Furthermore, we show how widely-available special-purpose hardware (in particular, z-buffering in graphics hardware) can be used for supporting buffer operations in fuzzy geographic information systems (GIS).

Does Campaigning on Social Media Make a Difference? Evidence From Candidate Use of Twitter During the 2015 and 2017 U.K. Elections

Political campaigning on social media is a core feature of contemporary democracy. However, evidence of the effectiveness of this type of campaigning is thin. This study tests three theories linking social media to vote outcomes, using a novel 6,000 observation panel data set from two British elections. We find that Twitter-based campaigning does seem to help win votes. The impact of Twitter use is small, though comparable with campaign spending. Our data suggest that social media campaign effects are achieved through using Twitter as a broadcast mechanism. Despite much literature encouraging politicians to engage with social platforms in an interactive fashion, we find no evidence that this style of communication improves electoral outcomes. In light of our results, theories of how social media are changing processes of campaigns and elections are discussed and enhanced.
On the expected discounted penalty function for a risk model with two classes of claims and random incomes

In this paper, we consider a risk model with two independent classes of insurance risks and random incomes. We assume that the two independent claim counting processes are, respectively, the Poisson and the Erlang(2) process. When the individual premium sizes are exponentially distributed, the explicit expressions for the Laplace transforms of the expected discounted penalty functions are derived. We prove that the expected discounted penalty functions satisfy some defective renewal equations. By employing an associated compound geometric distribution, the analytic expressions for the solutions of the defective renewal equations are obtained. Assuming that the distributions of premium sizes have rational Laplace transforms, we also give the explicit representations for the Laplace transforms of the expected discounted penalty functions.
Melanopsin Is Required for Non-Image-Forming Photic Responses in Blind Mice

Although mice lacking rod and cone photoreceptors are blind, they retain many eye-mediated responses to light, possibly through photosensitive retinal ganglion cells. These cells express melanopsin, a photopigment that confers this photosensitivity. Mice lacking melanopsin still retain nonvisual photoreception, suggesting that rods and cones could operate in this capacity. We observed that mice with both outer-retinal degeneration and a deficiency in melanopsin exhibited complete loss of photoentrainment of the circadian oscillator, pupillary light responses, photic suppression of arylalkylamine-N-acetyltransferase transcript, and acute suppression of locomotor activity by light. This indicates the importance of both nonvisual and classical visual photoreceptor systems for nonvisual photic responses in mammals.

Supply Management Governance Role in Supply Chain Risk Management and Sustainability

Supply chains face increased pressure from stakeholders to incorporate a plethora of corporate responsibility and sustainability aspects in their constituents’ business practices. Legal and extra-legal demands are dynamically changing; almost no industry, supply chain, organization, and an organizational function are unaffected. Owing to the outsourcing wave of the last decade (Reuter et al., 2010), in particular purchasing and supply management (PSM) plays an ever more important role in assuring sustainable supply chains in the marketplace. In order to manage supply chain risks, supply management must ensure that their local and international practices and relationships comply with their stakeholders’ expected codes of conduct and that environmental and social misconducts do not occur, while maintaining profitability. The proposed framework (Figure 1) highlights the “dynamic nature” of requisite supply management capabilities and governance mechanisms. This is mainly due to the need to creating a strategic fit between supply chains and the continually changing supply chain risks. This strategic fit denotes “supply chain resilience;” defined as "the capacity for a supply chain to survive, adapt, and grow in the face of turbulent change" (Pettit et al., 2010). Resilient supply chains are proposed to require certain forms of supply management governance, i.e., structures and processes intended to coordinate and integrate various dimensions of supply management. Governance represents the structures and processes by which supply chain constituents share power, also shapes individual and collective actions (Young, 1992). Despite interest, there is clear dearth of research on the nature of supply management’s role in sustainability. It would be of great insight to the supply management field to explore “What are the supply management capabilities and governance mechanisms used to sustain a supply chain? ” This conceptual study contributes to prior research in the fields of SM and supply chain sustainability by extending insights of the resilience and capabilities view to analyze how SM governance integrates sustainability aspects in its supply chain practices. This conceptual study responds to the need for well coordinated efforts that draw on established theories concerning supply chain’s sustainability. Building a supply chain sustainability theory offers not just scholarly but also practical value (Ketchen and Hult, 2011).
The effects of titanium mesh on passive-scattering proton dose

High-density metallic implants can introduce considerable uncertainties in proton therapy treatment planning. These uncertainties eventually translate into proton range errors, which may cause significant underdosing to the target volume or overdosing to normal tissue beyond the target. This study investigated the dosimetric impact of a 0.6 mm titanium (Ti) mesh implant in passive-scattering proton beam therapy through the study of the depth dose and output in water, and the dose profiles in solid water at various depths. The measurements were performed for a beam with a range of 8.5 cm and a modulation of 7.5 cm. The titanium mesh was placed at a depth of 1 cm below the surface of the phantom for all measurements. A range reduction of 0.5 ± 0.1 mm was observed for a beam perpendicular to the mesh, with no further reductions when the incident angle increased to 60°. We conclude that the dosimetric effect of a 0.6 mm titanium mesh implant is small for a passive scattering proton beam. With proper correction applied to metal artifacts, consistent results were observed in the phantom study in the treatment planning system.

Tissue Localization of Human Trefoil Factors 1, 2, and 3

Trefoil factors (TTFs) are small, compact proteins coexpressed with mucins in the gastrointestinal tract. Three trefoil factors are known in mammals: TFF1, TFF2, and TFF3. They are implicated to play diverse roles in maintenance and repair of the gastrointestinal channel. We compared the expression pattern of the three trefoil factors analyzing mRNA from a panel of 20 human tissues by conventional reverse transcriptase (RT) PCR and, in addition, by real-time PCR. These findings were supported by immunohistochemical analysis of paraffin-embedded human tissues using rabbit polyclonal antibodies raised against these factors. TFF1 showed highest expression in the stomach and colon, whereas TFF2 and TFF3 showed highest expression in stomach and colon, respectively. All three TFFs were found in the ducts of pancreas. Whereas TFF2 was found to be restricted to these two tissues, the structurally more closely related TFF1 and TFF3 showed a more general tissue distribution and were found to colocalize on an array of mucosal surfaces. This is the first thorough parallel description of the tissue distribution of TFFs in normal tissues, and it provides a baseline for similar analysis in diseased tissues.
Injeção de ácido ascórbico in ovo pré-incubação sobre parâmetros de incubação e hematológicos respiratórios

O presente estudo teve como objetivo verificar o efeito da injecao de acido ascorbico em ovos ferteis sobre parâmetros de incubacao e sanguineos. Oitocentos ovos ferteis de matrizes de frango de corte (Cobb®) com 36 semanas de idade foram pesados e distribuidos homogeneamente em quatro incubadoras, com controle automatico de temperatura, giro e umidade. Durante o periodo de incubacao utilizou-se uma temperatura de 37,5oC e 60% de umidade relativa ate a transferencia (19 dias de incubacao) e 70% de umidade relativa nos dois ultimos dias de incubacao. O delineamento utilizado foi o inteiramente casualizado, com cinco tratamentos aplicados antes da incubacao: ovos nao perfurados e, portanto nao injetados; ovos injetados com 100 μl de agua no albumem, com as seguintes concentracoes: 0, 2, 4 e 6% de acido ascorbico. As analises estatisticas foram realizadas pelo programa SAS ®. Os dados mostraram que os tratamentos utilizados nao prejudicaram o desenvolvimento in ovo sob condicoes termoneutras, exceto a eclosao, a qual foi influenciada por falta de habilidade na execucao da tecnica de injecao. Alem disso, a injecao de 6% de acido ascorbico aumentou o teor de hemoglobina, com melhora no potencial de transporte de gases no sangue destes pintainhos.
