Improved Mechanical Properties of NR/EPDM and NR/Butyl Blends by Precuring EPDM and Butyl

Ethylene-propylene-diene rubber (EPDM) and isobutylene-isoprene rubber (IIR) were compounded, precured to a low degree, and then were blended with natural rubber (NR). The compounding ingredients for NR were then added and the final curing was done. NR/ EPDM and NR/IIR blends, prepared using this method, were found to possess much improved mechanical properties as compared to their conventional counterparts. The optimum precuring crosslink density that has to be given to the EPDM and IIR phases has been determined.

Hydrogeological, Geophysical And Geochemical Studies In Parts Of Coastal And Midland Areas, Central Kerala - A Gis Approach

The present study deals with the different hydrogeological characteristics of the coastal region of central Kerala and a comparative analysis with corresponding hard rock terrain. The coastal regions lie in areas where the aquifer systems discharge groundwater ultimately into the sea. Groundwater development in such regions will require a precise understanding of the complex mechanism of the saline and fresh water relationship, so that the withdrawals are so regulated as to avoid situations leading to upcoming of the saline groundwater bodies as also to prevent migration of sea water ingress further inland. Coastal tracts of Kerala are formed by several drainage systems. Thick pile of semi-consolidated and consolidated sediments from Tertiary to Recent age underlies it. These sediments comprise phreatic and confined aquifer systems. The corresponding hard rock terrain is encountered with laterites and underlined by the Precambrian metamorphic rocks. Supply of water from hard rock terrain is rather limited. This may be due to the small pore size, low degree of interconnectivity and low extent of weathering of the country rocks. The groundwater storage is mostly controlled by the thickness and hydrological properties of the weathered zone and the aquifer geometry. The over exploitation of groundwater, beyond the ‘safe yield’ limit, cause undesirable effects like continuous reduction in groundwater levels, reduction in river flows, reduction in wetland surface, degradation of groundwater quality and many other environmental problems like drought, famine etc.

Survey of Agricultural Practices and Alternatives to Pesticide Use to Conserve Water Resources in the Mojanda Watershed, Ecuador

Agriculture in the Mojanda Watershed is facing rainfall reductions caused by climate change. Reductions of water availability in the Watershed are also due to constant extension of the agricultural activities into the páramo ecosystem above 3000m a.s.l., with this ecosystem having immanently important functions in the local water balance. The application of pesticides threatens the quality of water and with less precipitation contaminations will further concentrate in the outflow. To analyze problems associated with agricultural practices in the area a questionnaire about agricultural practices (28) was conducted and fields (20) were surveyed for pests and diseases with a focus on potatoes (Solanum tuberosum L.), tree tomatoes (Solanum betaceum Cav.) and peas (Pisum sativum L.). Potatoes were infected to a low degree with Phytophthora infestans and according to the farmers the Andean potato weevil (Premnotrypes spec.) caused biggest losses. To combat the weevil the soils are disinfected with toxic Carbofuran (WHO Class 1B). Tree tomatoes showed symptoms of various fungal diseases. Most important was Fusarium solani causing the branches to rot and Anthracnosis (Colletotrichum gloeosporioides) causing the fruits to rot. Fungicide applications were correspondingly high. Peas were only minorly affected by Ascochyta blight (Mycosphaerella pinodes) and a root rot. Overall 19 active ingredients were applied of which fungicide Mancozeb (WHO class table 5) and insecticide Carbofuran (WHO Class 1B) were applied the most. Approved IPM methods are advised to reduce pesticide use. For tree tomatoes regular cutting of branches infected with F. solani and regular collection and disposal of infected fruits with Anthracnosis are advised. For potatoes plastic barriers around the fields prevent the Andean potato weevil from laying eggs thus reducing infestation with the larvae in the tubers. Local bioinsecticide “Biol” seems effective and without harm to the environment, although not used by many farmers. Organic fertilization promises to restore decreasing soil fertility, water holding capacity and reduce erosion. The here presented alternatives and strategies to reduce pesticide use pose an opportunity to preserve the water resources of the region.

Individual Decision-Making and Inflation Persistence

The traditional task of a central bank is to preserve price stability and, in doing so, not to impair the real economy more than necessary. To meet this challenge, it is of great relevance whether inflation is only driven by inflation expectations and the current output gap or whether it is, in addition, influenced by past inflation. In the former case, as described by the New Keynesian Phillips curve, the central bank can immediately and simultaneously achieve price stability and equilibrium output, the so-called ‘divine coincidence’ (Blanchard and Galí 2007). In the latter case, the achievement of price stability is costly in terms of output and will be pursued over several periods. Similarly, it is important to distinguish this latter case, which describes ‘intrinsic’ inflation persistence, from that of ‘extrinsic’ inflation persistence, where the sluggishness of inflation is not a ‘structural’ feature of the economy but merely ‘inherited’ from the sluggishness of the other driving forces, inflation expectations and output. ‘Extrinsic’ inflation persistence is usually considered to be the less challenging case, as policy-makers are supposed to fight against the persistence in the driving forces, especially to reduce the stickiness of inflation expectations by a credible monetary policy, in order to reestablish the ‘divine coincidence’. The scope of this dissertation is to contribute to the vast literature and ongoing discussion on inflation persistence: Chapter 1 describes the policy consequences of inflation persistence and summarizes the empirical and theoretical literature. Chapter 2 compares two models of staggered price setting, one with a fixed two-period duration and the other with a stochastic duration of prices. I show that in an economy with a timeless optimizing central bank the model with the two-period alternating price-setting (for most parameter values) leads to more persistent inflation than the model with stochastic price duration. This result amends earlier work by Kiley (2002) who found that the model with stochastic price duration generates more persistent inflation in response to an exogenous monetary shock. Chapter 3 extends the two-period alternating price-setting model to the case of 3- and 4-period price durations. This results in a more complex Phillips curve with a negative impact of past inflation on current inflation. As simulations show, this multi-period Phillips curve generates a too low degree of autocorrelation and too early turnings points of inflation and is outperformed by a simple Hybrid Phillips curve. Chapter 4 starts from the critique of Driscoll and Holden (2003) on the relative real-wage model of Fuhrer and Moore (1995). While taking the critique seriously that Fuhrer and Moore’s model will collapse to a much simpler one without intrinsic inflation persistence if one takes their arguments literally, I extend the model by a term for inequality aversion. This model extension is not only in line with experimental evidence but results in a Hybrid Phillips curve with inflation persistence that is observably equivalent to that presented by Fuhrer and Moore (1995). In chapter 5, I present a model that especially allows to study the relationship between fairness attitudes and time preference (impatience). In the model, two individuals take decisions in two subsequent periods. In period 1, both individuals are endowed with resources and are able to donate a share of their resources to the other individual. In period 2, the two individuals might join in a common production after having bargained on the split of its output. The size of the production output depends on the relative share of resources at the end of period 1 as the human capital of the individuals, which is built by means of their resources, cannot fully be substituted one against each other. Therefore, it might be rational for a well-endowed individual in period 1 to act in a seemingly ‘fair’ manner and to donate own resources to its poorer counterpart. This decision also depends on the individuals’ impatience which is induced by the small but positive probability that production is not possible in period 2. As a general result, the individuals in the model economy are more likely to behave in a ‘fair’ manner, i.e., to donate resources to the other individual, the lower their own impatience and the higher the productivity of the other individual. As the (seemingly) ‘fair’ behavior is modelled as an endogenous outcome and as it is related to the aspect of time preference, the presented framework might help to further integrate behavioral economics and macroeconomics.

Prevalencia de ideación suicida y factores de riesgo para el suicidio en pacientes adultos con cáncer

En la revisión literaria desarrollada por la investigadora principal y el doctor Juan Gabriel Ocampo acerca del conocimiento actual del suicidio en pacientes oncológicos y que sirvió como base para la presente investigación, se encontró que si bien los pacientes con cáncer pueden desarrollar estrategias adecuadas de afrontamiento, también puede surgir en ellos, el deseo de morir como vía de escape para evitar el sufrimiento. Adicionalmente se identificó que en la actualidad no existen muchas investigaciones sobre el tema, por lo que surge la necesidad de desarrollar este estudio de tipo descriptivo exploratorio. La investigación se realizó en una clínica de tercer nivel en la ciudad de Bogotá-Colombia, especializada en población oncológica, con pacientes entre los 18 y 65 años, diagnosticados con cáncer y que asistían a la clínica al servicio de consulta externa, hospitalización o quimioterapia; lo anterior con el objetivo de establecer la prevalencia de ideación suicida e identificar los factores asociados a la misma en pacientes adultos con cáncer. La evaluación se realizo mediante una entrevista semiestructurada y la aplicación de los cuestionarios BHS, SSI y BDI-IA. Los resultados señalaron un bajo grado de ideación suicida en la población oncológica entrevistada y diversas asociaciones entre la ideación suicida y factores como depresión, desesperanza, dolor y fatiga. Igualmente se discuten asociaciones y datos relevantes que de muestran una necesidad real de la población oncológica de recibir atención psicológica, ya que presentan un importante grado de malestar psicológico que puede estar siendo descuidado.

Magnetotelluric deep soundings, gravity and geoid in the south Sao Francisco craton: Geophysical indicators of cratonic lithosphere rejuvenation and crustal underplating

In the south Sao Francisco craton a circular and 8-m amplitude geoid anomaly coincides with the outcropping terrain of an Archean-Paleoproterozoic basement. Broadband magnetotelluric (MT) data inversions of two radial profiles within the positive geoid and Bouguer gravity anomaly yield geo-electrical crustal sections, whereby the lower crust is locally more conductive (10 to 100 Omega m) in spatial coincidence with a denser lower crust modeled by the gravity data. This anomalous lower crust may have resulted from magmatic underplating, associated with Mesoarchean and Proterozoic episodes of tholeiitic dike intrusion. Long-period MT soundings reveal a low electrical resistivity mantle (20 to 200 Omega m) from depths beyond 120 km. Forward geoid modeling, using the scope of the low electrical resistivity region within the mantle as a constraint, entails a density increase (40 to 50 kg/m(3)) possibly due to Fe enrichment of mantle minerals. However, this factor alone does not explain the observed resistivity. A supplemented presence of small amounts of percolated carbonatite melting (similar to 0.005 vol.%), dissolved water and enhanced oxygen fugacity within the peridotitic mantle are viable agents that could explain the less resistive upper mantle. We propose that metasomatic processes confined in the sub-continental lithospheric mantle foster the conditions for a low degree melting with variable CO(2), H(2)O and Fe content. Even though the precise age of this metasomatism is unknown it might be older than the Early Cretaceous based on the evidence that a high-degree of melting in a lithospheric mantle impregnated with carbonatites originated the tholeiitic dike intrusions dispersed from the southeastern border of the Sao Francisco craton, during the onset of the lithosphere extension and break-up of the western Gondwana. The proxies are the NE Parana and Espinhaco (130 Ma, Ar/Ar ages) tholeiitic dikes, which contain (similar to 3%) carbonatites in their composition. The occurrence of a positive geoid anomaly (+ 10 m) and pre-tholeiites (age > 138 Ma), carbonatites and kimberlites along the west African continental margin (Angola and Namibia) reinforces the presumed age of the Sao Francisco-Congo craton rejuvenation to be prior to its fragmentation in the Lower Cretaceous.

Population genetic structure and dispersal in white-lipped peccaries (Tayassu pecari) from the Brazilian Pantanal

In many mammals social organization promotes genetic structuring, which can be influenced by the dispersal pattern of the species. We analyzed the population genetic structure and dispersal of white-lipped peccaries (Tayassu pecan) from the Pantanal, Brazil. We genotyped 100 individuals at 7 microsatellite loci from 2 adjacent locations with no obvious geographic barrier between them. We found a significant but low F(ST) value, and the Bayesian analysis indicated a unique cluster. No significant differences were observed between mean assignment indices of resident males and females from both locations, and the probability of being born at the location sampled of > 30% of the individuals analyzed was lower than average. Mean relatedness between resident female, male, and opposite-sex pairs was not statistically different in both locations. These results suggest a low degree of genetic differentiation between the locations analyzed, and dispersal by both sexes (contrary to the predicted male-biased dispersal of most mammalian species).

The role of oxygen in the interaction of emeraldine base polyaniline with Cu(II) or Fe(III) ions in NMP solution

The influence of molecular oxygen in the interactions of emeraldine base form of polyaniline (EB-PANI) with Fe(III) or Cu(II) ions in 1-methyl-2-pyrrolidinone (NMP) solutions has been investigated by UV-vis-NIR, resonance Raman and electron paramagnetic resonance (EPR) spectroscopies. Through the set of spectroscopic results it was possible to rationalize the role Of O(2) and to construct a scheme of preferential routes occurring in the interaction of EB-PANI with Fe(III) or Cu(II). Solutions of 4.0 mmol L(-1) EB-PANI with 0.8, 2.0 and 20 mmol L(-1) Fe(III) or Cu(II) ions in NMP were investigated and the main observed reactions were EB-PANI oxidation to pernigraniline (PB-PANI) and EB-PANI doping process by pseudo-protonation, or by a two-step redox process. In the presence Of O(2), PB-PANI is observed in all Fe(III)/EB solutions and EB-PANI doping only occurs in solutions with high Fe(III) concentrations through pseudo-protonation. On the other hand, emeraldine salt (ES-PANI) is formed in all Fe(III)/EB solutions under N(2) atmosphere and, in this case, doping occurs both by the pseudo-protonation and two-step redox mechanisms. In all Cu(II)/EB solutions PB-PANI is formed both in the presence and absence of O(2), and only for solutions with high Cu(II) concentrations doping process occurs in a very low degree. The most important result from EPR spectra was providing evidence for redox steps. The determined Cu(II) signal areas under oxygen are higher than under N(2) and, further. the initial metal proportions (1:2:20) are maintained in these spectra, indicating that Cu(I) formed are re-oxidized by O(2) and. so, Cu(II) ions are being recycled. Consistently, for the solutions prepared under nitrogen, the corresponding areas and proportions in the spectra are much lower, confirming that a partial reduction of Cu(II) ions actually occurs.

Att integrera i det svenska samhället : En undersökning om kvinnor med invandrarbakgrund och deras syn på introduktion och andra faktorer som påverkar inträdet i det svenska arbetslivet och samhället

The integration policy in Sweden shall encourage individuals to support themselves and take part in society. It shall alsocontribute to equal rights and opportunities for women as well as for men. In Borlänge this has resulted in a program ofintroduction for new arrivals from other countries. However, at the unit responsible for economic support, they havediscovered that women with immigrant background more often than men seem to have trouble starting or became to anending of the program, which then especially leads women to a long-term dependence for economic support. The purpose of this study has therefore been to investigate what factors affect immigrant women’s participation in theintroduction, and what significance this participation has for their possibilities to become economically self-supporting,and integrated into Swedish society. Previous research shows that some of the obstacles for the integration of immigrant women can be that they give birthto many children, are unskilled or have a low degree of education and that they tend to be living under patriarchalgender patterns. Another problem seem to be that some women are not even known as members of the municipalities.All of these problems are as well what was shown in my own study. I have used theoretical perspectives from Bourdieu, Elias & Scotson, Giddens, Roman and al-Baldawi in my analysis.Bourdieu have interesting thoughts about capital, habitus and field, which can help us to understand how individuals arebeing shaped and are given different opportunities to act in a special way or direction. Elias & Scotson describesthrough their study around established and outsiders how the process of integration can take place and what effects thatcan be shown for the opportunities to succeed in that part. Giddens, Roman and al-Baldawi then give us different waysto look at the patriarchy and family structures around the world. The result of this study shows that the willingness to integrate and be able to take care of your own support for living isan important part for the women for succeeding. For the other women, that don’t succeed, it turns out to be just like theprevious research has been shown. Gender patterns, many children and a low or no education skill all seems to be partof the issue. It is also suggested that the generosity of the Swedish welfare system might hinder rather than help someimmigrant women to become integrated into Swedish society.

UV-shielding ceramic nanoparticles synthesised by mechanochemcial processing

ZnO, TiO₂ and CeO₂ are known as UV-shielding ceramic materials that have advantages over organic UV absorbers for their photo-stability and non-hazardous nature to human bodies. However, they normally cause low transparency in the visible-light range due to light scattering by large particles, which is undesirable for many transparent UV-blocking applications in cosmetic and plastic industries. Light-scattering efficiency of particles can be drastically reduced by decreasing the particle sizes down below 100 nm. This paper reviews recent investigation on the synthesis of ZnO and CeO₂ nanoparticles by mechanochemical processing. The resulting particles had a significantly low degree of agglomeration, having mean particle sizes of ~ 25 nm and ~ 10 nm, respectively. The aqueous suspensions of the nanoparticles showed strong absorption in the UV-light range and high transmittance in the visible-light range. Mechanochemical processing offers the possibility of industrial-scale production of transparent UV-shielding ceramic particles for many applications.

Enhancement of ion dissociation in polyelectrolyte gels

High conductivity in single ion conducting polymer electrolytes is still the ultimate aim for many electrochemical devices such as secondary lithium batteries. Achieving effective ion dissociation in these cases remains a challenge since the active ion tends to remain in close proximity to the backbone charge as a result of a low degree of ion dissociation. A unique aspect of this dissociation problem in polyelectrolytes is the repulsion between the backbone charges created by dissociation. One way of enhancing ion dissociation in polyelectrolyte systems is to use copolymers in which only a fraction (<20%) of the mer units are charged and where the comonomer is itself chosen to be polar and preferably to be compatible with potential solvents. We have also found that certain dissociation enhancers based on ionic liquids or boroxine ring compounds can lead to high ionic conductivity. In the cases where an ionic liquid is used as the solvent in a polyelectrolyte gel, the viscosity of the ionic liquid and its hydrophilicity are critical to achieving high conductivity. Compounds based on the dicyanamide anion appear to be very effective ionic solvents; polyelectrolyte gels incorporating such ionic liquids exhibit conductivities as high as 10⁻² S/cm at room temperature. In the case of boroxine ring dissociation enhancers, gels based on poly(lithium-2-acrylamido-2-methyl-1-propanesulfonate) and ethylene carbonate produce conductivities approaching 10⁻³ S/cm. This paper will discuss these approaches for achieving higher conductivity in polyelectrolyte materials and suggest future directions to ensure single ion transport.

Análise digital de imagem e estereologia da angiogênese em adenomas e no adenocarcinoma colorretal invasivo de submucosa

A angiogênese é essencial no desenvolvimento neoplásico, associando-se às metástases à distância e recorrência em diversas neoplasias malignas. Em carcinomas colorretais, os parâmetros da análise digital de imagem e estereologia da angiogênese foram pouco estudados. Objetivo: avaliar parâmetros tridimensionais e a quantificação microvascular bidimensional nas diferentes apresentações morfológicas dos adenomas colorretais e no adenocarcinoma colorretal restrito à submucosa, a fim de determinar o papel da angiogênese nas diferentes etapas da seqüência adenoma-carcinoma e sua relação com as diferentes apresentações das lesões precursoras do carcinoma colorretal. Material e métodos: foi realizado estudo histórico de delineamento transversal, incluindo 115 lesões neoplásicas colorretais, ressecadas endoscópica ou cirurgicamente no período de 1997 a 2001, obtidas de pacientes do Hospital de Clínicas de Porto Alegre e da Fundação Universitária de Gastroenterologia (FUGAST). Para análise da angiogênese foram utilizadas as técnicas de imuno-histoquímica, análise digital de imagem, quantificação microvascular e estereologia. Os resultados foram apresentados como mediana e intervalos interquartis. Resultados: a quantificação microvascular foi progressivamente mais elevada nas lesões polipóides com displasia de alto grau comparadas às de baixo grau. Quanto maior o grau de atipia observado, maior foi o número de microvasos (regressão linear, P < 0,05). O volume e extensão microvascular foram diferentes entre as fases evolutivas da neoplasia colorretal, resultando em aumento no volume 728 (416 - 1408) versus 178 (93 - 601) e extensão microvascular 242,4 (131,1 - 936,8) vs 24,0 (6,5 - 142,2) (P < 0,001) nas lesões polipóides com displasia de alto grau comparadas às de baixo grau, respectivamente. A quantificação microvascular foi progressivamente mais elevada, acompanhando a progressão neoplásica polipóide: displasia de baixo grau 41,8 (15,8 - 71,9), displasia de alto grau 60,0 (23,0 - 95,6) e carcinoma de submucosa 76,0 (37,5 - 132,6) (P < 0,001). Concomitante, o volume 956 (436 - 2188) vs 178 (93 - 601) e a extensão microvascular 534,6 (146,7 - 1262) vs 24,0 (6,5 - 142,2) foram mais elevados nos adenocarcinomas colorretais restritos à submucosa em relação às lesões polipóides com displasia de baixo grau, respectivamente (P < 0,001). Não foi encontrada diferença estatisticamente significativa na angiogênese entre os adenomas polipóides e não-polipóides através da quantificação 41,8 (15,8 - 71,9) vs 22 (16 - 40) e estimativa da extensão microvascular 24 (6,5-142,2) vs 17,5 (4,4-54,7), respectivamente. Conclusão: a utilização da análise digital de imagem e estereologia acrescentou maior objetividade e eficácia na metodologia de avaliação angiogênica, pois permitiu a precisa segmentação das áreas hipervasculares, a representação da morfologia tridimensional característica do suprimento vascular e a identificação de diferenças na microvascularização nas etapas evolutivas do câncer colorretal.

Inserção de pessoas com deficiência intelectual: um estudo em empresas situadas na região metropolitana de São Paulo

Esta dissertação teve origem no questionamento sobre as reais possibilidades de inclusão das pessoas com deficiência intelectual (PCDI), cada vez mais frequentemente inseridas nas organizações brasileiras. O objetivo principal é analisar a maneira como tem acontecido a inserção de PCDI em cinco grandes empresas situadas na região metropolitana de São Paulo, a partir das perspectivas das pessoas diretamente envolvidas. Isso implica, primeiramente, em uma contextualização das políticas de inserção adotadas pelas organizações participantes. Além disso, a partir da análise dos temas mais abordados pelas pessoas entrevistadas, pretende-se identificar os significados da inserção das pessoas com deficiência intelectual e suas implicações mais relevantes para as pessoas envolvidas: os sujeitos com deficiência intelectual, seus chefes, pares hierárquicos de convivência direta, profissionais de gestão de pessoas e pessoas vinculadas a organizações externas, mas que de alguma forma influenciam ou interferem nas atividades de inserção e inclusão no ambiente organizacional. Como arcabouço teórico foram abordados os conceitos de inclusão, inserção e diversidade nas organizações; preconceito, estigma e demais barreiras atitudinais à inclusão; questões familiares e educacionais; as concepções de deficiência ao longo da história, além de aspectos demográficos e regulatórios relacionados ao tema. A pesquisa foi realizada por meio de entrevistas com baixo grau de estruturação e as transcrições analisadas conforme a abordagem de análise de conteúdo proposta por Bardin (1977), a partir dos pressupostos do interacionismo simbólico estrutural (STRYKER, 2006). A partir da discussão dos temas que emergiram da análise de conteúdo e da contextualização e comparação das políticas de inserção adotadas pelas organizações, pôde-se concluir que é possível incluir as pessoas com deficiência intelectual, tendo em vista as fronteiras organizacionais em que elas se inserem.
