Particle size of Saharan dust in the Atlantic Ocean, from October 2012 to November 2013

Mineral dust has a large impact on regional and global climate, depending on its particle size. Especially in the Atlantic Ocean downwind of the Sahara, the largest dust source on earth, the effects can be substantial but are poorly understood. This study focuses on seasonal and spatial variations in particle size of Saharan dust deposition across the Atlantic Ocean, using an array of submarine sediment traps moored along a transect at 12° N. We show that the particle size decreases downwind with increased distance from the Saharan source, due to higher gravitational settling velocities of coarse particles in the atmosphere. Modal grain sizes vary between 4 and 33 µm throughout the different seasons and at five locations along the transect. This is much coarser than previously suggested and incorporated into climate models. In addition, seasonal changes are prominent, with coarser dust in summer, and finer dust in winter and spring. Such seasonal changes are caused by transport at higher altitudes and at greater wind velocities during summer than in winter. Also the latitudinal migration of the dust cloud, associated with the Intertropical Convergence Zone, causes seasonal differences in deposition as the summer dust cloud is located more to the north, and more directly above the sampled transect. Furthermore, increased precipitation and more frequent dust storms in summer coincide with coarser dust deposition. Our findings contribute to understanding Saharan dust transport and deposition relevant for the interpretation of sedimentary records for climate reconstructions, as well as for global and regional models for improved prediction of future climate.

AUSÊNCIA PATERNA E SUAS REPERCUSSÕES SOBRE O DESENVOLVIMENTO INFANTIL

O presente estudo teve por objetivos a) investigar as repercussões da ausência paterna sobre o desenvolvimento da criança; b) descrever o conteúdo intrapsíquico de crianças com pais presentes e de crianças com pais ausentes no lar. Para tanto foram estudados três casos de crianças em idade escolar que freqüentavam uma instituição não governamental da cidade de Santos e utilizou-se dos instrumentos entrevista semi-estruturada com as mães e Procedimento de Desenho-Estória com Tema com as crianças. A aplicação foi feita nos seguintes termos, pediu-se ao participante que desenhasse uma criança e, em seguida que contasse uma estória sobre o desenho. Após, foi solicitado à criança que desenhasse o pai dessa criança e que contasse uma estória sobre esse mesmo desenho. Optamos também por aplicar o Teste das Matrizes Coloridas de Raven - Escala Especial com as crianças. Embora cada caso tivesse revelado suas peculiaridades, os resultados mostraram indicativos de distúrbios da identidade sexual, desamparo, insegurança, tendências depressivas, além de associação entre a ausência paterna, déficit cognitivo e/ou inibição intelectual. Foi também observado em um dos casos, dificuldades da mãe em permitir que o pai paternasse . Concluiu-se que a ausência paterna foi percebida pela criança não somente como a falta da pessoa do pai no lar, mas sim por sua omissão; somando-se ao fato de que a internalização da figura paterna não pareceu determinada pelo laço biológico, mas sim pela possibilidade de oferecimento à criança de identificação e afeto. Entendeu-se com esse estudo que o desenvolvimento psíquico saudável pode ser facilitado pela introjeção das boas figuras materno/paternas pela criança. Sendo assim, estudos dedicados ao tema da paternidade são tão importantes de serem explorados na atualidade quanto o foram aqueles destinados à maternidade ao longo da história da psicologia do desenvolvimento e da psicanálise.

Tools for fluorescent molecularly imprinted polymers

A linear co-polymer of hexyl acrylate and quinine acrylate was prepared anchored to cellulose filtration membranes. These were used to probe quenching of the tethered fluorophore by test compounds in solution for the validation of imprinted polymer fluorescence studies. The results are compared with simple solution phase quenching studies and also for two membrane-bound imprinted polymers containing the same fluorophore. © 2004 Elsevier B.V. All rights reserved.

Matrix changes induced by transglutaminase 2 lead to inhibition of angiogenesis and tumor growth

Administration of active TG2 to two different in vitro angiogenesis assays resulted in the accumulation of a complex extracellular matrix (ECM) leading to the suppression of endothelial tube formation without causing cell death. Matrix accumulation was accompanied by a decreased rate of ECM turnover, with increased resistance to matrix metalloproteinase-1. Intratumor injection of TG2 into mice bearing CT26 colon carcinoma tumors demonstrated a reduction in tumor growth, and in some cases tumor regression. In TG2 knockout mice, tumor progression was increased and survival rate reduced compared to wild-type mice. In wild-type mice, an increased presence of TG2 was detectable in the host tissue around the tumor. Analysis of CT26 tumors injected with TG2 revealed fibrotic-like tissue containing increased collagen, TG2-mediated crosslink and reduced organized vasculature. TG2-mediated modulation of cell behavior via changes in the ECM may provide a new approach to solid tumor therapy.

In vitro hydrolytic degradation of centrifugally spun polyhydroxybutyrate-pectin composite fibres

BACKGROUND: Centrifugal spinning is a novel fibre-forming process that readily permits the incorporation of additives while avoiding the thermal damage often associated with conventional melt spinning. Centrifugal spinning of a viscous solution of poly(3-hydroxybutyrate) (PHB) mixed with pectin was used to fabricate a range of fibres containing different concentrations of this biologically active agent. The influence of this blending on fibre morphology and in vitro degradation in an accelerated hydrolytic model at 70 ?C and pH of 10.6 is reported. RESULTS: Blending influenced the physiochemical properties of the fibres, andthis significantly affected thedegradation profile of both the fibre and its PHB constituent. A greater influence on degradation was exerted by the type of pectin and its degree of esterification than by variations in its loading. CONCLUSION: Centrifugal spinning permits the fabrication of composite fibrous matrices from PHB and pectin. Incorporation of the polysaccharide into the fibres can be used to manipulate degradation behaviour and demonstrates a model for doping of matrices with active biological constituents. The unique features of the centrifugal spinning process, as illustrated by the structure of the fibres and the degradation profiles, suggest possible applications of centrifugally spun biopolymers as wound scaffolding devices and in tissue engineering.

An Iterative Method for the Matrix Principal n-th Root

In this paper we give an iterative method to compute the principal n-th root and the principal inverse n-th root of a given matrix. As we shall show this method is locally convergent. This method is analyzed and its numerical stability is investigated.

Comparing Entire Prototypes at Semigroup Homomorphisms and Specifically at Regular Languages Substitutions

The following statements are proven: A correspondence of a semigroup in another one is a homomorphism if and only if when the entire prototype of the product of images contains (always) the product of their entire prototypes. The Kleene closure of the maximal rewriting of a regular language at a regular language substitution contains in the maximal rewriting of the Kleene closure of the initial regular language at the same substitution. Let the image of the maximal rewriting of a regular language at a regular language substitution covers the entire given regular language. Then the image of any word from the maximal rewriting of the Kleene closure of the initial regular language covers by the image of a set of some words from the Kleene closure of the maximal rewriting of this given regular language everything at the same given regular language substitution. The purposefulness of the ¯rst statement is substantiated philosophically and epistemologically connected with the spirit of previous mathematical results of the author. A corollary of its is indicated about the membership problem at a regular substitution.

Evaluating digital diabetic retinopathy screening in people aged 90 years and over

To evaluate the effectiveness of digital diabetic retinopathy screening in patients aged 90 years and over.MethodsThis is a retrospective analysis of 200 randomly selected patients eligible for diabetic retinopathy screening aged 90 years and over within the Birmingham, Solihull, and Black Country Screening Programme.ResultsOne hundred and seventy-nine (90%) patients attended screening at least once. 133 (74%) annual screening after their first screen, of whom 59% had no detectable diabetic retinopathy; 38 (21%) were referred for ophthalmology clinical assessment-36 for nondiabetic retinopathy reasons and two for diabetic maculopathy. Cataract accounted for 50% of all referrals for ophthalmology clinical assessment. Of the 133 patients placed on annual screening, 93 (70%) were screened at least once more. In terms of level of diabetic retinopathy, assessability or other ocular pathologies, 8 improved, 51 remained stable, and 31 deteriorated. Of the latter, 19 patients were referred for ophthalmology clinical assessment; none of these for diabetic retinopathy.ConclusionsScreening provides opportunistic identification of important nondiabetic retinopathy eye conditions. However, in view of the low identification rate of sight-threatening diabetic retinopathy in patients aged 90 years and over, and the current mission statement of the NHS Diabetic Eye Screening Programme, systematic annual diabetic retinopathy screening may not be justified in this age group of patients, but rather be performed in optometric practice.

Bevándorlók a magyar társadalom tükrében. Méltóság, igazságosság és civil integráció

A kötet tanulmányai – empirikus szociológiai kutatási tapasztalatok alapján – azt vizsgálják, hogy a bevándorlók és a magyar társadalom tagjai miként értelmezik a politikai és civil aktivitást. Hogyan függ ez össze a materiális, kulturális és társadalmi erőforrásokkal, az identitással, az akciópotenciállal, valamint a méltányosság- és méltóságérzettel? Az itt elemzett minták reprezentálják a hazai társadalmat és a tartózkodási, bevándorlási, letelepedési engedéllyel rendelkezőket, akiket összefoglalóan bevándorlóknak hívunk. Hangsúlyoznunk kell, hogy az általunk megkérdezett bevándorlók nem azonosak a menekülttáborok lakóival, vagy az illegálisan foglalkoztatott külföldiekkel. A bevándorlók ugyan maguk is számos problémával küzdenek, de lényegesen kedvezőbb helyzetben vannak, mint a menekülttáborok lakói vagy a szürke gazdaságban foglalkoztatottak, s ezt is tudatosítani kell az olvasás során.
