SummaryOne hundred and fifty-six consecutive patients with clinically suspected pulmonary embolism (PE) had blood drawn to measure levels of D-dimer and thrombin-antithrombin (TAT) complexes and underwent ventilation/perfusion (V/Q) lung scanning and bilateral impedance plethysmography (IPG); pulmonary angiography was performed in 10 patients. Patients were classified as: PE-positive (positive pulmonary angiography or high probability lung scan or non-high probability lung scan and abnormal IPG) or, PE-negative (normal lung scan or normal pulmonary angiography) or PE-unlikely (non-high probability lung scan and normal serial IPG and absence of venous thromboembolism in follow-up). Thirty patients were classified as PE-positive, 64 as PE-negative and 62 patients as PE-unlikely. PE-positive patients were treated with anticoagulants, whereas PE-negative and PE-unlikely patients were not. PE-unlikely patients were followed for 3 months with repeat IPG and clinical evaluation for the occurrence of venous thromboembolism. The sensitivities, specificities, positive predictive values and negative predictive values of the D-dimer and TAT complex assays were calculated for patients classified as PE-positive and PE-negative. In addition, the prevalences of normal D-dimer and TAT complex assays were calculated for PE-unlikely patients.Cutoffs of 300 ng/ml for D-dimer and 3.5 μg/ml for TAT complexes provided sensitivities of 96% for both assays, negative predictive values of 97% for D-dimer and 96% for TAT complexes and specificities of 52% for D-dimer and 51% for TAT complexes. The specificities of the assays were higher in patients without comorbid conditions and in outpatients. Among PE-unlikely patients, 14 had normal D-dimer levels and 5 had normal levels of TAT complexes. None of these patients developed venous thromboembolism in follow-up.Our study indicates that: 1) PE is highly unlikely in patients who have D-dimer levels of less than 300 ng/ml and/or levels of TAT complexes below 3.5 μg/ml, and 2), because of their relatively low positive predictive values, further investigation is required if levels of D-dimer and/or TAT complexes are above these cutoffs. These results should be confirmed in future clinical management trials.

This paper studies the mechanical properties of polyethylene (PE)–Single-walled carbon nanotube (SWCNT) complexes by using density functional theory (DFT). At the PBE/SVP level, the Young’s modulus of the complexes is obtained as a function of PE content. It is established that, with increasing number of PE chains attached to the SWCNTs, the Young’s modulus monotonically decreases. The density of states (DOS) results show that no orbital hybridization exists between the PE chains and nanotubes. The results of this work are of importance for the design of composite materials employing SWCNTs.

Full textAbstract:
The paper describes ways for controlling the molecular structure of polyethylene (PE) produced over supported catalysts containing bis(imino)pyridyl complexes of Fe(II) (LFeCl2) and bis(imine) complexes of Ni(II) (*LFeCl2), which are anchored on silica gel modified by the introduction of alumina (SiO2(Al)). Under variation of polymerization conditions over LFeCl2 /SiO2(Al) catalysts, linear PE with different molecular weight and controllable molecular-weight distribution (MWD) was obtained. Homopolymerization of ethylene over *LNiBr2 /SiO2(Al) catalysts led to the formation of branched PE with the molecular-weight and thermophysical characteristics close to the low-density polyethylene produced by ethylene copolymerization with α-olefins over supported metallocene catalysts and supported Zieglertype catalysts. A method was proposed for constructing the supported bicomponent catalysts containing LFeCl2 and *LNiBr2 complexes anchored on the SiO2(Al) support for the deliberate production of polyethylene with the required molecular structure. There are examples of obtaining the linear PE with bimodal MWD on a bicomponent supported catalyst containing two different LFeCl2 complexes, the PE with controllable branching distribution on a bicomponent catalyst synthesized by anchoring LFeCl2 and *LNiBr2 complexes on the SiO2(Al) support, and an example of modifying the industrial chromium oxide catalyst by introducing the LFeCl2 complex for the control of MWD and branching distribution in the produced polyethylene.

SummaryPrevious investigations suggested that heparin administration to humans enhances the tissue type plasminogen activator (tPA) levels in blood, but it remains uncertain whether this effect induces fibrinolysis. We studied the effect of therapeutic levels of heparinization on plasma markers for fibrinolysis in patients suspected of pulmonary embolism (PE). Blood samples were taken from 49 consecutive patients; 28 had confirmed PE, 21 had PE excluded.On admission, the plasma levels of plasmin-α2antiplasmin complexes and D-dimer were significantly higher in the patient group with PE compared to those in whom PE was excluded. After heparinization the tPA levels increased in both groups, showing that this effect was not dependent on the initial level of activity of fibrinolysis. In spite of this increment in tPA levels, the concentrations of plasmin-α2antiplasmin complexes and D-dimer decreased.In conclusion, although heparinization in patients with or without pulmonary embolism does lead to elevated tPA: Ag levels, this is not accompanied by enhanced fibrinolysis.

Full textAbstract:
Electrostatic interactions of polymeric charges become one of the important factors to form the polyelectrolyte complexes (PECs). In this work, PECs has successfully created through the interaction between positive charges of chitosan (CS) and negative charges of pectin (PE) based on the effect of pH and pKa of the polymers. The formation of PECs provides small particle size, positive surface charge, and high %entrapment efficiency (%EE) after loaded metronidazole (MTZ). Dropwise addition of PE solution into CS solution was carried out to form PECs. A certain concentration of chitosan and pectin fixed at ratio 3:1 while the pH of both polymers varied as pH 1, 3, 5, and 9. The alterations after forming PECs observed particle size, zeta potential, and turbidity of the solution along with FTIR, DSC, and TAG. Precipitation of PECs solution was found in the fixed pH 5 of PE solution dropwise into pH 7 and 9 CS solution, which referred to the unstable of the PECs system. The pH 1 and 9 of PE and CS obtained the large size which about 600-1200 nm, while zeta potential found a low positive charge of 5.54-11.90 mV. Thus, only the fixed pH 5 of CS solution and pH 3, 5, or 7 of PE solution to form PECs were used to load MTZ. After loaded MTZ, the particle size of the PECs was about 400-500 nm and the zeta potential was about 20-50 mV. Electrostatic interactions resulted from FTIR detected the changes in amino groups of CS and carboxyl groups of PE. Thermal analysis on DSC for determinations of melting points or transition temperatures and TGA to monitor weight loss by heat were confirmed the PECs and MTZ-PECs formation. The pH 5 of PE interacts with pH 5 of CS offered the smallest particle size as 438 nm, zeta potential about 23.5 mV, and the highest percentage of EE as about 50% of the drug-loaded. The pH 5 of PE and CS were the pH-responsive to the pKa, thus, the acidity of the polymers may provide a suitable condition to form the appropriate polyelectrolyte complexes.

Full textAbstract:
The mitochondrial outer membrane contains proteinaceous machineries for the import and assembly of proteins, including TOM (translocase of the outer membrane) and SAM (sorting and assembly machinery). It has been shown that the dimeric phospholipid cardiolipin is required for the stability of TOM and SAM complexes and thus for the efficient import and assembly of β-barrel proteins and some α-helical proteins of the outer membrane. Here, we report that mitochondria deficient in phosphatidylethanolamine (PE), the second non-bilayer-forming phospholipid, are impaired in the biogenesis of β-barrel proteins, but not of α-helical outer membrane proteins. The stability of TOM and SAM complexes is not disturbed by the lack of PE. By dissecting the import steps of β-barrel proteins, we show that an early import stage involving translocation through the TOM complex is affected. In PE-depleted mitochondria, the TOM complex binds precursor proteins with reduced efficiency. We conclude that PE is required for the proper function of the TOM complex.

La modification de la microstructure, de l'interdiffusion et les interactions intermoléculaires induites par l'ajout d'EVA en couche PE de films PE/liant/PA améliorent la soudabilité et les propriétés optiques, sans dégrader les performances mécaniques ni l'adhésion. Seule la glissabilité est détériorée. L'ajout d'EVA en couche liante augmente l'adhésion PEgMAH/PA6-66 par création de liaisons hydrogène entre l'acétate de vinyle et le PA6-66 et amélioration de la mouillabilité à chaud. L'utilisation d'un PA6 ramifié dégrade l'adhésion PEgMAH/PA6 qui est gouvernée par le temps de contact entre les polymères. La glissabilité a été ajustée par l'ajout d'agents glissants en couche (PE+EVA) dont l'efficacité est limitée par la présence des couches adjacentes et la formation d'une couche de surface non homogène. L'utilisation de nanocharges en couche PA6 conduit à une amélioration significative des performances mécaniques mais modeste de l'imperméabilité à l'oxygèneThe modification of the microstructure and the interdiffusion as well as the intermolecular interactions induced by addition of EVA in the PE layer PE/binder/PA packaging films improve the seal ability and the optical properties without degradation of the mechanical and adhesion performances. Only the sleep ability is deteriorated. The addition of EVA in the tie layer improve the PEgMAH/PA6-66 adhesion properties modification of the type and the density of the intermolecular interactions between tie layer, PA and EVA. The substitution of a linear PA6 by a branched leads to a degradation of the PEgMAH/PA6 adhesion properties which is mainly controlled by the contact time between the polymers. The slip ability was adjusted by addition of slip agents in the (PE+EVA) layer whose efficiency is limited by the presence of the adjacent layers and the formation of a non-uniform lubricating layer. The use of nanofillers in the PA6 layer leads to an improvement of the mechanical properties but a limited reduction of the gas permeability

Full textAbstract:
Cette thèse vise à concevoir, synthétiser et étudier des systèmes photo-stimulables modèles en solution aqueuse formés à partir de polyélectrolytes (PEs) et de tensioactifs. La photosensibilité est liée à la présence de chromophores azobenzène (Azo) qui subissent une isomérisation trans → cis sous irradiation UV. Nous avons considéré dans un premier temps un PE hydrophile sur lequel nous avons greffé des groupements Azo. Ce système forme de agrégats globulaires en solution en raison du collapse des chaînes et des associations intermoléculaires. La taille des agrégats varie sous irradiation UV. Elle dépend également de la masse molaire des PEs et du taux de greffage des groupements Azo. Nous avons considéré dans un second temps des tensioactifs dans lesquels des groupements Azo ont été introduits (Azo-tensioactifs). Nous avons étudié leur complexation avec des PEs de charge opposée. Ces systèmes s’organisent en colliers de perles. Les polyions décorent les micelles et pénètrent à l’intérieur de celles-ci (co-micellisation). Sous irradiation UV, la taille des perles diminue sans vraiment modifier l’organisation des complexes. Nous nous sommes enfin intéressés à l’auto-assemblage d’Azo-tensioactifs et de co-tensioactifs. Ce mélange conduit à la formation des micelles allongées et à la création d’un gel. Sous irradiation UV, on observe une transition gel - fluide. L’origine ce phénomène est lié à un changement morphologique des agrégats micellaires (micelles allongées - micelles globulaires)This thesis aims at designing, synthesizing and characterizing model photo-responsive systems in aqueous solution. These systems are based on polyelectrolytes (PEs) and surfactants. The photo-sensitivity arises from the presence of azobenzene (Azo) groups that undergo a transition from a trans to a cis isomer. We first considered a hydrophilic PE on which we grafted Azo groups. This system forms globular aggregates in solution due to chains collapse and intermolecular associations. The size of the aggregates varies under UV irradiation. It also depends on the molar mass of the PEs and the Azo content. We then considered surfactants in which Azo groups have been introduced (Azo-surfactants). We studied their complexation with oppositely charged PEs. These systems show a pearl necklace organization. The PEs decorate the micelles and penetrate inside (co-micellisation). Under UV irradiation, the size of the pearls decreases without really modifying the general organization of the complexes. Finally, we were interested in the self-assembly of Azo-surfactants and co-surfactants. This mixture leads to the formation of wormlike micelles and the creation of a gel. Under UV irradiation, a gel - fluid transition is observed. The origin of this phenomenon is linked to a morphological transition of the micellar aggregates (wormlike micelles - globular micelles)

Resumo: O estado de Pernambuco passa por um período de reestruturação econômica e territorial dinamizado, entre outros vetores, pela construção e consolidação de uma infraestrutura logística voltada para o mercado externo ¿ com destaque para o porto de Suape e sua estratégia de concentrar cargas a nível internacional; por empreendimentos estruturadores lastreados pelo governo federal ¿ com destaque para a Refinaria Abreu e Lima - RNEST, a Petroquímica Suape ¿ PQS e o Estaleiro Atlântico Sul - EAS, todos no Complexo Industrial e Portuário de Suape - CIPS; e por investimentos privados atraídos por incentivos fiscais. Objetiva-se verificar se os investimentos recentes no CIPS ocorrem de forma articulada de modo a promover a integração inter setorial da economia local e/ou no sentido de integrá-la aos circuitos de valorização de capitais extra-locais, nacionais e internacionais. A hipótese que se demonstrará é que tais investimentos não ocorrem de formar a aumentar a integração da estrutura produtiva pernambucana, mas obedecem a outras determinações impostas pelo atual padrão de acumulação capitalista

Previous issue date: 2010Estuda os possíveis impactos socioambientais da implantação do Complexo Turístico Imobiliário The Reef Club na cidade de Barreiros-PE. Estes empreendimentos resultam da integração dos resorts com o turismo residencial, demandam investimentos na casa dos bilhões de reais e provocam fortes transformações onde se instalam. Se expandem rapidamente na costa nordestina em função de condições extremamente favoráveis para a expansão do capital especulativo. O fio condutor do estudo foi comprovar a incapacidade do The Reef Club , e o modelo que ele representa, de promover a reversão da fragilidade socioambiental e econômica de Barreiros. Para que isto fosse possível foi estabelecido como objetivo principal a identificação dos possíveis impactos socioambientais que a comunidade poderá sofrer com a chegada do The Reef Club , possibilitando ao final a identificação de alternativas à este modelo que possibilitassem a melhoria das condições de vida, justiça social, respeito a natureza e o fortalecimento do capital social da comunidade barreirense. Os objetivos específicos estabelecidos foram a análise da atual situação da atividade turístico-imobiliária no Brasil e no exterior; o atual quadro de ocupação da zona costeira nordestina pela atividade turística; o processo de desenvolvimento do turismo tradicional, face a inexistência de projetos turísticos imobiliários em fase efetiva de funcionamento na região; e por último a análise do projeto de implantação do empreendimento The Reef Club e da estrutura socioambiental, econômica e institucional do município de Barreiros. Para que os objetivos fossem atingidos a pesquisa se desenvolveu de forma exploratória e qualitativa com base na triangulação de métodos (MINAYO, 2005), se utilizando de técnicas como a pesquisa bibliográfica, pesquisa documental, entrevista, observação assistemática e registro fotográfico. A análise e interpretação dos dados da pesquisa permitiram que ao final fosse possível concluir pela incapacidade do modelo turístico-imobiliário de reverter o grave quadro de fragilidade social de Barreiros, haja vista seu caráter eminentemente capitalista e especulativo, e que diante desta da fragilidade o quadro deverá se agravar. Ao final sugere-se que outras pesquisas se aprofundem no tema, tendo em vista a incipiência de estudos que abordem a problemática do excessivo processo de ocupação da zona costeira nordestina pela atividade turístico-imobiliária. Com forma de contribuir com a reversão da fragilidade socioambiental e econômica de Barreiros, sugerem-se alternativas, como a da Prainha do Canto Verde, no Ceará, que passam por modelos baseados na educação, participação e envolvimento da comunidade, que ao mesmo tempo em que a empoderam, possibilitam a formação do capital social, em um ciclo virtuoso que, ao contrário do capital econômico, não se acaba, pondo fim aos nativos mudos , formando-se, então, uma rede de solidariedade e comportamento recíproco, onde os valores sociais e culturais são partilhados

Na fase primária da infecção pelo HIV, o vírus penetra no Sistema Nervoso Central (SNC) e estabelece um reservatório viral protegido. A infecção crônica do SNC pode levar a complicações neurodegenerativas com a possibilidade de gerar transtornos da função cognitiva e déficits dos processos mentais, tais como atenção, aprendizado, memória, rapidez do processamento de informações, capacidade de resolução de problemas e sintomas sensoriais e motores. O Distúrbio Neurocognitivo Associados ao HIV (HAND) tem merecido atenção devido ao potencial em determinar impacto funcional desfavorável na vida das pessoas vivendo com HIV (PVHIV), como dificuldade na execução das atividades da vida diária e necessidade de assistência para garantir adesão às medicações. Além disso, os pacientes apresentam dificuldade em manter seus empregos, necessitando de uma melhor assistência social. O diagnóstico clínico do HAND é idealmente baseado no desempenho dos testes neuropsicológicos. Entretanto, a aplicação destes testes é impraticável em muitos cenários clínicos, principalmente em países subdesenvolvidos. A Escala Internacional de Demência pelo HIV (IHDS) é um teste de triagem rápido, validado para a população brasileira que, de acordo com o ponto de corte estabelecido, pode detectar todas as formas do HAND (assintomática, leve e demência). Realizamos um estudo transversal, com comparação de grupos, para estimar a freqüência do HAND por meio da IHDS. As variáveis quantitativas foram descritas por meio de média, enquanto que as qualitativas foram representadas por distribuição de freqüência. As associações dos fatores relacionados ao HAND foram testadas utilizando o teste Qui-Quadrado de Pearson. Foram estudadas 98 PVHIV entre 18 e 50 anos, sem outras doenças neurológicas e psiquiátricas, atendidas nos ambulatórios de dois centros de referências para o tratamento do HIV em Recife- PE. Também foram excluídas da pesquisa as pessoas em uso de efavirenz e drogas ilícitas nos 30 dias que antecederam a entrevista. Utilizou-se como critério diagnóstico do HAND um ponto de corte ≥ 11 na IHDS, cuja sensibilidade e especificidade é de 78% e 52%, respectivamente. Encontrou-se uma elevada prevalência (66,7%) do HAND e uma associação entre o distúrbio e as pessoas com mais idade e do sexo feminino. O diagnóstico de depressão e o uso de terapia antirretrovial (TARV) com menor penetração no SNC (CPE < 8) foi mais freqüente entre as mulheres e essa associação foi estatisticamente significante (P = 0,001 e P = 0,028, respectivamente), o que poderia justificar a maior prevalência do HAND no sexo feminino. Esse trabalho alerta para a necessidade de se realizar uma triagem nas PVHIV para o HAND uma vez que parece uma comorbidade frequente, principalmente entre as pessoas com mais idade e do sexo feminino, com a finalidade de auxiliar nas estratégias de melhoria à adesão terapêutica e na oferta de TARV com maior efetividade de penetração no SNC e de medicações psicotrópicas quando necessárias.

The main goal of this study was to evaluate the structure of a forest fragment in the municipal district of Catende/PE, seeking to subsidize future actions that can conserve and/or recover the forest fragment of Usina Catende. The study was accomplished in the fragment denominated “Forest of the Chinkens”, located in the Engenho Huimatá. The phytosociologic structure was determined with use of 14 plots of 10x25m (250m2), distributed in parallel lines with 50 meters among lines and plots. It was measured all the sampled trees with circumferences at the breast height (CBH) equal or superior to 10 cm. In the trees with bifurcation all the trunks were measured. The following phytosociologic variables were measured: density, frequency, dominance, importance value (IV) and sociological position. The estimate of the phytosociologic parameters were obtained with the use of the software “Native Forest”. The analysis of sampling sufficiency of the floristic composition was accomplished through the methodology of the specie distribution curves by area. For the diameters and height distribution it was considered class of 5 cm and 2 m, respectively. With the sample sufficiency accomplished it was observed 438 tres/3.500m2 with 63 species distributed in 29 families which 46 were identified at the species level, 11 at gender level, 2 at the family level e 4 were not identified. The families that presented larger frequency were Moraceae, Lecythidaceae,Mimosaceae and Anacardiaceae. The fragment presented index of diversity of Shannon-Weaver of 3,43 nats./ind. being compatible with other studies in Pernambuco. The ten species with larger values of IV were Brosimum discolor, Parkia pendula, Eschweilera ovata, Thyrsodium spruceanum, Tapirira guianensis, Protium heptaphyllum, Casearia arborea, Helicostylis tomentosa, Dialium guianense and Schefflera morototoni, tha represented 57,99; 41,74; 64,60 and 54,78%, of density, frequency, dominancy and importance value of the total sampled species. In the evaluation of the height it was observed a minimum height of 3,6 m and maximum of 22,00 m, with average of 8,67 m and standard deviation of 4,04 m. it was verified that 10 species were in three strata: Brosimum discolor, Brosimum sp.,Casearia arborea, Cecropia palmata, Dialium guianense, Escweilera ovata, Himatanthus phagedaenicus, inga fagifolia, Protium heptaphyllum and Thyrsodium spruceanum. The studied fragment presents low floristic diversity although it presents compatible diversity with other studies accomplished in Atlantic Forest. The families of larger importance in the study were Moraceae, Anacardiaceae and Lecythidadeae. Among the main sampled just the Brosimum discolor, Eschweilera ovata and Thyrsodium spruceanum presented a regular sociological position. The total diameter structure was similar to even aged forests, with the distribution in decreasing geometric form (inverted J). The studied fragment possesses little relevance; however, if considered jointly with other fragments of the area, its diversity is significant, justifying efforts to its conservation and management in landscape scale.
Objetivou-se avaliar a estrutura de um fragmento florestal no Município de Catende/PE, visando subsidiar futuras ações que possam conservar e/ou recuperar os fragmentos da Usina Catende. O estudo foi realizado no fragmento florestal denominado Mata das Galinhas, localizado no Engenho Humaitá. A estrutura fitossociológica foi determinada com o uso de 14 parcelas de 10 x 25 m (250 m2) distribuídas em linhas paralelas com 50 m entre linhas e entre parcelas. Foram mensuradas todas as árvores com circunferência igual ou superior a 10 cm a altura de 1,30m solo (CAP). Para cada árvore amostrada, mediu-se CAP e estimou a altura. Nas árvores com bifurcações foram mensurados todos os fustes. Em seguida foram estimados os valores da fitossociológica tais como: densidade, freqüência e dominância e valor de importância (VI), e determinou-se, ainda, a posição sociológica. A estimativa da diversidade foi obtida utilizando-se o índice de diversidade de Shannon. Os cálculos das estimativas dos parâmetros fitossociológicos foram obtidos por meio do uso do programa de informática Mata Nativa. A análise da suficiência amostral da composição florística foi realizada através da metodologia de curva de distribuição de espécies por área. Para o estudo da distribuição hipsométrica e diamétrica foram consideradas amplitudes de classe de 2 m e 5 cm, respectivamente. De acordo com a análise de suficiência amostral realizada, o número de parcelas utilizadas pôde contribuir com resultados confiáveis da composição florística mais representativa da vegetação estudada, bem como, das estimativas dos parâmetros fitossociológicos encontrados. No levantamento da composição florística foram observados 438 indivíduos/3500m2 e 63 espécies, distribuídas em 29 famílias, as quais 46 foram identificadas ao nível de espécie, 11 ao nível de gênero, 2 ao nível de família e 4 não identificadas. As famílias que apresentaram maior freqüência foram a Moraceae, Lecythidaceae, Mimosaceae e Anacardiaceae. O fragmento apresentou índice de diversidade de Shannon-Weaver de 3,43 nats/ind, sendo compatível com outros estudos em Pernambuco. As dez espécies com maiores valores de VI foram Brosimum discolor, Parkia pendula, Eschweilera ovata, Thyrsodium spruceanum, Tapirira guianensis, Protium heptaphyllum, Casearia arborea, Helicostylis tomentosa, Dialium guianense e Schefflera morototoni, e representaram 57,99, 41,74, 64,60 e 54, 78%,respectivamente, da densidade, da freqüência, da dominância e do valor de importância do total das espécies amostradas. Na avaliação da altura observou-se uma altura mínima de 3,6 m e máxima de 22,00 m, tendo como média 8,67 m e desvio padrão igual a 4,04 m. Verificou-se que 10 espécies encontram-se nos três estratos, que são: Brosimum discolor; Brosimum sp.; Casearia arborea; Cecropia palmata; Dialium guianense; Eschweilera ovata; Himatanthus phagedaenicus; Inga fagifolia; Protium heptaphyllum e Thyrsodium spruceanum. O fragmento estudado apresenta baixa riqueza florística, embora apresente diversidade compatível com outros estudos realizados em Mata atlântica. As famílias de maior importância no estudo foram Moraceae, Anacardiaceae e Lecythidaceae. Entre as principais espécies amostradas, apenas o Brosimum discolor Schott., Eschweelera ovata e Thryrsodium spruceanum apresentaram uma posição sociológica regular. A estrutura diamétrica total da floresta apresentou comportamento previsto para florestas ineqüiâneas, com a distribuição em forma geométrica decrescente (J invertido). O fragmento estudado possui pouca relevância; entretanto, se considerado conjuntamente com outros fragmentos da área, sua diversidade é significativa, o que justificaria esforços para sua conservação e manejo em escala de paisagem

In particular, the role that can play the Lewis acid within the coordination sphere of the metal is investigated, thanks to combined experimental and computational analyses. The first chapter introduces the context and main goals of this work. The second chapter focuses on the study of metal->Lewis acid interactions supported by ambiphilic ligands. A description of the very nature of the Au->B interaction is proposed in the case of diphosphine borane complexes. The influence of the nature of the metallic fragment on the M->B interaction strength is also assessed through in depth study of seven isoelectronic triphosphine borane complexes. The third chapter tackled the limit of existence of M?B interactions by combining a weakly basic metal with flexible ligands. Multi-centre coordination modes are evidenced within a family of copper mono- and di- phosphine borane complexes. This study demonstrates the ability of ambiphilic ligands to adapt their coordination to the electronic demand of the metal centre. In the forth chapter, the influence of the Lewis acid nature on the coordination mode of ambiphilic ligands is investigated. Unexpectedly, the complexation of di- and tri- phosphine alane ligands to gold leads to zwitterionic complexes, resulting from the internal activation of the M-X bond by the Lewis acid. In contrast, the complexation of phosphine gallane ligands affords both neutral and zwitterionic coordination isomers, isolable or exchanging depending on the number of donor buttresses

O que as paisagens tem a dizer sobre a sociedade e/ou comunidades? A paisagem é especificada pela subjetividade cultural assim como se refere a objetos concretos e ecossistemas ecológicos, é a interação complexa desses termos. Contudo, as paisagens estão imbuídas de significados e significantes, que dependem do parâmetro tempo, da historicidade. A memória conecta com um passado imagético, ajuda a reconhecer nos elementos simbólicos e nas representações sociais valores socioculturais e ambientais. Desta forma, aquela contribui para a avaliação de mudanças na paisagem. Nesta dissertação, a paisagem a ser estudada é a da Comunidade Quilombola Onze Negras no Cabo de Santo Agostinho, Pernambuco. As imagens nos arquivos mentais pessoais podem ser acessados com um trabalho construído por uma outra imagem, a fotográfica. Esta estimula a expressão individual e coletiva, mostra mais das histórias de um povo do que qualquer documento descritivo individual, que se pretende verificar. Quando as imagens são captadas pela própria comunidade quilombola por suas representantes mulheres, revelam seus valores, elementos simbólicos e a análise do discurso visual permitirá esclarecer como está a paisagem, o ambiente e assim propiciar uma ação ambiental que resulta na práxis de estimular a superação da contradição opressor-oprimidos . Esta contradição está presente na cultura da mata sul pernambucana dentro da fábrica no campo , a indústria da cana de açúcar. Não se sabe, porém, se este modelo continuará a ser reproduzido no novo sistema econômico que se estabelece na região: o complexo industrial portuário. Sabe-se que a atividade industrial influi diretamente no montante do PIB, elevando a renda, que está ligado ao IDH, índice que avalia se o desenvolvimento está se convertendo em benefício social, mas não em qualidade de vida. A proposta desta discussão é avaliar como está a paisagem e suas mudanças na comunidade quilombola Onze Negras, verificar uma correlação entre as imagens, a paisagem e os índices; e se as melhorias dos índices são reproduzidas pelas imagens

This study aims to understand the territorial transformations that is related to the advent of scientific-technical-information period, through which Ipojuca town has been undergone. Ipojuca is located in Pernambuco State, in Brazil. We have tried to understand how the techniques and standards imposed by hegemonic agents have been vertically articulated to suit the territory to the market needs. As a methodological design, this research has been developed from bibliographic survey and visits to Ipojuca in order to understand the roles played by several elements that are part of this process, thus, enabling the comprehension of its social and territorial dynamics. The study also shows that the profound transformations that refigure the territory of Ipojuca started in 1975 with the implementation of the Industrial Port Complex of Suape (IPSC) which generated conflicts, concerning the use and occupation of the soil. It has been observed that the connection between the Capital and the State created the conditions necessary for the installation of a new technical system represented by the IPSC, as well as standards that ensured the adequacy of this territory to the imperative of the market. Thus, it has resulted in an exclusive process of the division of territory. One of the consequences of the actions of this mega-enterprise was the expulsion of the local communities who had lived there more than 200 years and were forced to occupy part of this territory with the construction of slums and stilts. On the other hand, the economic agents, through public funding, modernized portions of this territory with the construction of urban projects, such as, “Planned Neighborhoods”. This dynamic made oppositions when it comes to the fact that, on one side, the population is living in irregular land occupations and, on the other hand, those with better economical power is expanding the social and territorial segregation. The relationship between the hegemonic agents of the national/international capital have been using the technique, science and information intensively, as well as the various State entities in their favor to impose the logic business where space is only seen by its exchange value, neglecting its value in use. Thus, it has been noted that both the technical and the legal system have been seen as factors that increase the of social and territorial inequalities and vulnerabilities which have been observed in Ipojuca town.
Este trabalho busca entender as transformações territoriais pelas quais passa o município do Ipojuca localizado no Estado de Pernambuco-Brasil, relacionadas ao advento do período técnico-científico-informacional. Procurou-se compreender como as técnicas e as normas impostas verticalmente pelos agentes hegemônicos foram se articulado para adequar o território as necessidades do mercado. A pesquisa foi desenvolvida a partir de levantamento bibliográfico e de visitas a este município para o entendimento dos papéis desenvolvidos pelos diversos elementos que fazem parte desse processo, possibilitando a compreensão de sua dinâmica socioterritorial. O estudo mostra que as profundas transformações que reconfiguram o território do Ipojuca começam a partir de 1975 com a implantação do Complexo Industrial Portuário do Suape (CIPS) que gerou conflitos relativos ao uso e ocupação do solo. Observou-se que a comunhão entre Capital e Estado criou as condições necessárias para a instalação de um novo sistema técnico representado pelo CIPS, e normas que garantiram a adequação deste território ao imperativo do mercado, tendo como consequência um processo excludente de divisão do território. Uma das consequências das ações deste megaempreendimento foi a expulsão das comunidades locais que ali residiam a mais de 200 anos e que foram obrigadas a ocupar parte deste território com a construção de favelas e palafitas. Por outro lado os agentes econômicos imobiliários, através de financiamentos públicos, modernizam parcelas deste território com a construção de projetos urbanísticos denominados ‘Bairros Planejados’. Esta dinâmica opondo, de um lado, a população que mora em ocupações irregulares e, do outro, aquelas com melhores poderes aquisitivo está ampliando a segregação socioterritorial. A relação entre os agentes hegemônicos do capital nacional e internacional utilizando-se intensivamente da técnica, da ciência e da informação e os diversos entes do Estado vai impondo uma lógica corporativa onde o espaço é visto apenas pelo seu valor de troca negligenciando seu valor de uso. Desta maneira, tanto o sistema técnico, quanto o normativo, constituiram-se como fatores de ampliação das desigualdades e das vulnerabilidades sociais e territoriais observadas no município do Ipojuca.

Marketingul cultural, domeniu in plina expansiune in contextul dezvoltarii industriei creative, are la dispozitie, prin aceasta teza, importante resurse stiintifice teoretice si practice, care completeaza golurile de cunoastere in acest sector si contribuie la identificarea unui instrumentar specific si adaptat de lucru. Lucrarea pune la dispozitia cercetatorilor o revizie critica a literaturii de specialitate si o incadrare teoretica riguroasa a sectorului studiat, bazata pe asemanarile care includ domeniul in sfera mai larga a marketingului sectorial al serviciilor, precum si pe particularitatile care-i asigura identitate proprie. Trei tipuri de cercetari complexe (exploratorie, calitativa si cantitativa), au permis identificarea operatorilor din sectorul artelor spectacolului din Bucuresti si evaluarea modului in care acestia utilizeaza elementele mixului de marketing in dialog cu segmentele-tinta carora li se adreseaza. Rezultatele acestor studii, validate prin multiple metode stiintifice, au stat la baza realizarii unui model conceptual de cercetare, care permite evaluarea unor elemente dominate de variabile subiective, respectiv satisfactia consumatorilor, si factorii care influenteaza perceptia legata de calitatea serviciilor prestate.

Turismul reprezinta un fenomen social, cultural si economic care vizeaza mobilitatea oamenilor catre locuri necunoscute, dincolo de granitele resedintei lor conventionale, fiind de obicei motivati de placere sau alte interese personale. Turismul reprezinta un complex de activitati dinamice care definesc puternic performanta economica a secolului al XXI‑lea. Pe harta lumii, putem observa o crestere a numarului de noi destinatii turistice, care cuprind o serie de tari emergente, cu un flux sporit de turisti internationali. Cresterea substantiala a numarului de turisti, in special in Asia de Sud‑Est, dar si in Orientul Mijlociu, a contribuit la cresterea importantei economice a turismului pe plan mondial. Aceasta dezvoltare rapida a turismului in tari cu economii emergente este un fenomen tipic, care se produce in epoca postindustriala si este sustinut de accesul turistilor la obiective culturale, religioase, evenimente sportive si altele.

In actualul context economico-financiar, comertul cu amanuntul este un domeniu complex, vital si provocator, dezvoltat in special in cadrul tarilor care au o economie emergenta. Este de mentionat inca de la inceput, faptul ca, acest sector este un sector foarte dinamic, ce presupune schimbari rapide intr-o perioada scurta de timp. Tendintele cheie si evolutiile sale, precum schimbarea nevoilor consumatorilor si interesul acestora pentru experienta de cumparare mai mult decat pentru produsul in sine, consolidarea pozitiei marilor firme de comert cu amanuntul, aparitia strategiilor de comert cu amanuntul de tip multi canal, schimbarea naturii competitiei in interiorul si intre diferitele forme de comert cu amanuntul, precum si descoperirea noilor tehnologii, au un impact dramatic asupra modului in care firmele cu importante retele de comert cu amanuntul se dezvolta in perioada urmatoare. Acestea sunt principalele argumente care au stat la baza intentiei de cercetare a acestui domeniu, cu accent pe identificarea strategiilor de marketing utilizate.

Full textAbstract:
Traumatic events, including sexual abuse, experiencing or witnessing violence, and natural disasters, are common among adolescents, and this online therapist guide presents a proven treatment for PTSD that has been adapted for the adolescent population. It applies the principles of Prolonged Exposure (PE) to help adolescents emotionally process their traumatic experiences and follows a four-phase treatment where the patients complete each module at their own rate of progress. It includes modules on motivational interviewing, case management, the rationale for treatment, information-gathering about the trauma, common reactions to trauma, and explains that by systematically confronting situations associated with the trauma, adolescents can overcome avoidance and fear. It covers how memory of the traumatic event can help distinguish the past from the present and promote feelings of mastery, and also includes modules on relapse prevention and treatment termination. It covers the importance of the adolescent's age and developmental level while in therapy, and includes developmentally appropriate materials and guidance on tailoring the treatment to each client's unique situation, including trauma type and family structure.

Dansul - arta vie, complexa - poate fi, cu greu, introdus in cutia limbajului scris ori vorbit; semnul plat (litera) nu poate reda vibratia dansanta a vietii, la fel cum marea n-ar putea fi inchisa intr-o camera. Dansul contemporan este jocul cu spatiul, timpul, emotia, este un domeniu al cercetarii continue, o cercetare libera, un dialog dinamic al fortelor interioare si exterioare ale omului pentru a se descoperi pe sine sau, mai departe - pentru a ajunge in inima universului. Miscarea contine dimensiuni infinite, a le pune in cuvinte inseamna a risca… Dar poate ca, pentru memoria dansului, merita riscul - gestul coregrafic trebuie uneori condensat, descris prin cuvinte pentru a putea sa traiasca mai departe, la fel de liber. In dans, metafora capata trup, emotia devine spatiu, timp. Scenele se succed, iar in urma lor, din miscarea trupurilor, ne ramane visul. Miscarea este gand, elan, zbatere si, adesea, ne aduce in lumina sufletul. Omul in miscare demonstreaza ca este mai mult decat ceea ce pare, iar dansul devine un instrument revelator de meta-realitati.

Lucrarea de fata reprezintă o incercare de cercetare sistematică a fenomenelor și tehnicilor traductologice evidentiate în talmacirile romanesti ale romanului Le Château des Carpathes/ Castelul din Carpati, cu scopul de a releva marcile diacronice ale limbii romane literare, de-a lungul celor o suta douazeci si cinci de ani de confruntare cu scrierile lui Jules Verne. Textul Le Château de Carpathes/Castelul din Carpati, despre care discutam aici, s-a bucurat de un succes deosebit in epoca si in posteritate, ajungand la sensibilitatea cititorilor romani, dar si a traducatorilor, intrucat acesta valorifica o limba literara in care terminologia stiintifica de la nivelul de popularizare a stiintelor se îmbina cu elementele stilului beletristic: un vocabular complex, presarat cu expresii metaforice, cu forme arhaice, regionale, dar mai ales cu imprumuturi, cu neologisme obtinute pe aceasta cale a imprumutului sau prin creatii interne partiale ori totale – calcuri lingvistice, derivate, compuse, conversiuni, combinatii intre toate acestea. In plus, romanul in cauza a reprezentat un prilej de mandrie nationala, dat fiind faptul ca Transilvania, un colt de tara romaneasca, a provocat un interes deosebit pentru anticipatorul stiintific francez – un autor de talie mondiala.

Full textAbstract:
Evaluarea psihologica clinica este un proces etapizat, sistematic, extrem de complex, ce se adreseaza atat functiilor psihice cat si personalitatii umane, ce trebuie sa ia in considerare o multitudine de aspecte care adesea nu sunt evidente, nici aparente. Inainte de a primi tratament medicamentos sau prin interventie psihologica, orice client trebuie sa treaca prin aceasta etapa fundamentala - evaluarea psihologica ce poate face ca terapia sa poata fi eficienta si adecvata. Este extrem de important ca evaluarea psihologica ce preceda interventia psihologica sa fie efectuata in baza unor ipoteze clinice, multimodal si corect, asa cum este prezentata in acest volum. Rezultatele evaluarii clinice trebuie, ulterior evaluarii, formulate intr-un limbaj profesionist, de specialitate, comun psihologiei si psihiatriei. Accesul viitorilor psihologi la acest vocabular de specialitate trebuie sa se faca inca de pe bancile facultatii, cunoasterea semnelor si simptomelor bolilor psihice, a principalelor entitati semiologice psihiatrice fiind extrem de importanta. Scopul urmarit de aceasta carte este acela de a oferi un set rezonabil de informatii de specialitate abordate intr-o maniera didactica, fluida, pornind de la principii de baza si continuand cu metode de lucru, cazuri particulare si analiza diverselor cadre in care acestea pot fi puse in practica. Importanta temei abordate deriva din binomul formare informare. Acest volum este deci important din perspectiva formativa pentru ca pune la dispozitia studentilor, masteranzilor in psihologie, psihologilor cu competente in consiliere, psihoterapie, psihologie clinica, dar si a celor cu alte competente, altor lucratori in domeniul sanatatii mintale, un ghid exhaustiv de semiologie a manifestarilor modurilor normale sau anormale in care fiecare proces si functie psihica poate functiona, imbogatite cu exemple din cazuistica proprie a autoarei sau din literatura de specialitate, ce faciliteaza considerabil intelegerea. Valenta informativa vine din adresarea catre categoria larga a altor persoane care sunt interesate de perspectiva psihologiei asupra bolii psihice.

AbstractDisorders of ejaculations are among the most complex complaints of patients seeking first medical help for sexual dysfunction. Among these, premature ejaculation (PE), delayed ejaculation (DE), retrograde ejaculation, and anorgasmia are the most frequently reported, and their impact on patients’ quality of life can be major. Although numerous preclinical and clinical studies have been published over the last two decades, the true pathophysiological mechanisms behind ejaculation remain unclear. In this context, this chapter aims at providing the latest evidence regarding ejaculation physiology together with detailed epidemiological data, diagnostic work-up, and treatment options upon PE, DE, retrograde ejaculation, and anorgasmia.

Full textAbstract:
This chapter articulates the anti-skeptical line of response afforded by PE. It is also shown that while the promised anti-skeptical bite of other appearance-based theories, such as PC, dissolves when one becomes reflectively aware of one’s own appearances, the same is not true of PE. This not only addresses a perennial concern for internalist theories but also completes the case for the superiority of PE over both PC and similar theories that do not take on board explanationist insights. This chapter shows that PE offers all that one might want from PC and much more. So, PE is an important theory of epistemic justification that is worthy of serious consideration.

Full textAbstract:
Massive pulmonary embolism (PE) is associated with high mortality. Besides thrombolytic therapy and surgical embolectomy, extracorporeal life support (ECLS) can be a relevant therapy option. This chapter reviews the management of a complex patient from the onset of the event through extracorporeal membrane oxygenation (ECMO) cannulation and clinical management of serious and life-threatening complications. ECMO therapy has to be seen in conjunction with other available treatments in massive PE. A case discussion followed by a critical review of the literature and critical care board-type multiple choice questions summarize this chapter as a concise learning and study tool for the management of patients with PE on ECMO.

Full textAbstract:
Despite elevated prevalence rates of trauma and post-traumatic stress disorder (PTSD) in eating disorder (ED) individuals, there is a surprising lack of data on how to effectively treat this population. The most significant gaps in the literature include the “what” (which PTSD treatment to use) and “when” (sequential vs. concurrent treatment) of PTSD treatment. Clinicians are often fearful in working with this ED subgroup, particularly given that these patients often report high-risk behaviors such as suicidality and self-harm. This chapter presents a new approach to treating comorbid PTSD that seems to be very promising for ED–PTSD patients. Borrowed from dialectical behavior therapy (DBT), this approach (called DBT PE) outlines readiness criteria and a protocol for altering the treatment plan if concerning behaviors emerge during the course of PTSD treatment. ED clinicians are encouraged to use DBT PE principles and to disseminate their results.

Full textAbstract:
Familia Formicidae reprezintă un grup de insecte sociale, împreună cu viespile și albinile face parte din ordinul Hymenoptera. Furnicile sunt implicate în diverse procese în natură: zoocoria, amestecarea solului și îmbogățirea lui cu substanțe organice, combaterea insectelor dăunătoare și îngrijirea altor insecte (Frouz, Jilkova, 2008). În Republioca Moldova până în prezent au fost publicate doar 4 lucrări cu referire la biodiversitatea furnicilor de pe teritoriul țării: Поддубный и др., 1980, Верещагин и др., 1983, Животный мир Молдавии, 1983 și Лиховидов, 1984. Conform acestor publicații studiu asupra furnicilor s-a efectuat preponderent în Rezervația științifică Codrii. În urma studiilor efectuate pe teritoriul Republicii Moldova între anii 1958-1981 au fost identificate 51 de specii de furnici. În urma colectărilor efectuate în rezervație în anii 2020-2021 au fost identificate, în premieră pentru fauna Rezervației „Plaiul Fagului”, 15 specii de furnici, care aparțin la 8 genuri și fac parte din 2 subfamilii. Dintre speciile identificate, Colobopsis truncata (Spinola, 1808), Lasius platythorax Seifert, 1991 și Temnothorax crassispinus (Karavaiev, 1926) sunt noi pentru fauna Republicii Moldova. Diversitatea speciilor de furnici din Republica Moldova poate să fie substanțial îmbunătățită prin studii faunistice complexe din cele mai diverse habitate, care să caracterizeze mai bine nivelul de cunoaștere a mirmecofaunei. Cercetările de pe teritoriul Rezervației „Plaiul Fagului” trebuie să fie continuate, dat fiind fapul că numărul speciilor cunoscute până în prezent în Republica Moldova este de 54, deci putem să ne așteptăm la un număr mult mai mare de specii de furnici în ecosistemele naturale diverse ale rezervației. Pe teritoriul rezervației au fost identificate două specii de furnici Formica polyctena și Formica pratensis, care sunt incuse în lista IUCN a speciilor amenințate cu dispariția la nivel internațional.

Full textAbstract:
Studii referitoare la diversitatea și ecologia speciilor de țânțari din Rezervația „Plaiul Fagului” nu au fost făcute până în 2010, deci se cunoaște foarte puțin despre speciile de Culicidae, dar și despre habitatele preferate din rezervație. Cu scopul studierii diversității speciilor de Culicidae din Rezervația „Plaiul Fagului” au fost inspectate corpurile acvatice permanente și temporare, potențiale locuri de reproducere a larvelor de țânțari. Adulții de țânțari au fost colectați în diverse habitate în septembrie 2010, iunie 2011, octombrie 2012, iunie 2018 și mai-iunie 2021. Stadiile imature ale țânțarilor au fost colectate din lacuri, bălți și acumulări de apă temporare rămase în urma ploilor abundente și din scorburile arborilor bătrâni. Colectările țânțarilor adulți au fost efectuate cu ajutorul aspiratorului manual din sediul rezervației și alte construcții augziliare ale Rezervației „Plaiul Fagului”. În timpul cercetărilor au fost identificate cinci tipuri de habitate favorabile pentru dezvoltarea larvelor de țânțari. Larvele și adulții au fost identificați până la specie sau complex de specii în conformitate cu cheile taxonomice publicate de Gutsevich ș.a., 1970 și Becker ș.a., 2010. La Culex pipiens pipiens și Culex torrentium identificarea s-a făcut pe baza structurii organelor genitale ale masculului. Pentru nomenclatura și prezentarea sistematică a speciilor de țânțari s-a folosit „Catalogul sistematic al culicidelor” de pe site-ul Unității de biosistematică Walter Reed. Ca rezultat al cercetărilor efectuate în Rezervația „Plaiul Fagului” au fost identificate 13 specii de țânțari din familia Culicidae, care aparțin la patru genuri: Anopheles, Aedes, Culex și Culiseta. Au fost colectați 361 de țânțari, în stadii diferite de dezvoltare, 343 dintre acestea reprezintă forme imature, adică 95%. Femelele au fost colectate de pe oameni, în procesul de căutare a sângelui uman (n = 16), iar masculii (n = 2), au fost prinși cu aspiratorul manual în timp ce se odihneau pe vegetația ieracee. Până în prezent pe teritoriul Republicii Moldova au fost semnalate 41 de specii de țânțari. Dintre acestea, 13 specii (32%), sunt menționate pentru prima dată din Rezervația „Plaiul Fagului”. Ecosistemele studiate includ corpuri de apă variabile, atât permanente, cât și temporare, favorabile pentru dezvoltarea larvelor de țânțari. Este de așteptat ca diversitatea speciilor de țânțari din rezervația „Plaiul Fagului” să fie cu mult mai mare și monitorizarea ulterioară cu studii suplimentare ar putea extinde lista speciilor de țânțari, care sunt parte componentă a rețelei trofice a altor insecte și animale.

Prima lucrare dedicată colembolelor din Rezervația „Plaiul Fagului” a fost publicată de Bușmachiu (2006) și includea 53 de specii, din 12 familii. În volumul Doniță ș.a., 2008 au fost incluse 63 de specii, colectate din sol și litiera a 11 parcelele experimentale din rezervație. Inventarierea speciilor colectate în decursul întregului an calendaristic între 2005 – 2008 a permis evidențierea deja a 103 specii de colembole, colectate în sol, litieră, mușchi, lemn descompus, luncă umedă, mal de lac, pășune și lucernă (Bușmachiu, 2008). De pe teritoriul rezervației au fost descrise două specii de colembole noi pentru știință: Xenylla andrzeji Bușmachiu & Weiner, 2008 și Neanura moldavica Bușmachiu & Deharveng, 2008. Date privind speciile de colembole colectate din rezervație fac parte din lucrările de siteză publicate pe parcursul anilor (Bușmachiu & Weiner, 2010, 2017 etc.). Rezultatele cercetărilor incluse în acest capitol au fost obținute în urma unui studiu complex, multianual al diversității de specii, dinamicii sezoniere și populațiilor de colembole începând cu anul 2005 și până în 2021 și include speciile de colembole care populează cele mai diverse habitate ale Rezervației Plaiul Fagului. Ca rezultat al studiului multianual complex (2005-2021) a celor mai diverse tipuri de habitate existente pe teritoriul rezervației au fost identificate 149 de specii de colembole, care se atribuite la 65 de genuri și fac parte din 18 familii, dintre care 46 sunt citate în premieră pentru rezervație. Analiza taxonomică scoate în evidenţă că în rezervație net dominante sunt speciile familiilor Entomobryidae (34), Isotomidae (23), Neanuridae (18), Hypogastruridae (16), Onychiuridae (11) și Tullbergiidae (10). Un număr mic de specii a fost depistat din familiile Katiannidae (6), Sminthuridae și Tomoceridae (câte 5), Arrhopalitidae (4), Neelidae și Dicyrtomidae (câte 3), Odontellidae, Brachystomellidae, Cyphoderidae, Bourletiellidae și Sminthurididae (câte 2), iar familia Poduridae cu o singură specie. În prezent, dintre toate rezervațiile din Republica Moldova, fauna colembolelor din Rezervația „Plaiul Fagului” este cel mai bine studiată, fiind unică din punct de vedere al diversității speciilor, incluzând specii rare, elemente carpatice și specii endemice.

The operating environment of polyethylene (PE) gas pipeline is complex and changeable. In the process of pipeline design, construction and operation, there are many fuzzy factors inducing pipeline accidents. In the paper, the fuzzy factors causing pipeline accidents were studied and analyzed, and the risk evaluation factors of PE gas pipeline were determined. According to the theory of fuzzy comprehensive evaluation, the mathematical model of fuzzy comprehensive evaluation for PE pipeline was established. In order to pursue as much accurate results of assessment as possible, the fuzzy analytic hierarchy process was used to determine the weight of each index. The safety evaluation grade of the pipeline was given by using the risk matrix method. And then the evaluation system software of PE gas pipeline risk assessment was developed. The software has been used in the risk inspection of PE gas pipeline, which provides the basis for the risk management of the pipeline.

In the present study the in vitro capillary perfusion system according to Cazenave was used. This system consists of a capillary tube connected to a syringe containg the perfusate which consisted of washed human platalet (111 In-labeled or native) and washed red cells in Ca2+ /Mg2+ -containing Tyrode-albumin buffer. Perfusate flow is controlled by a syringe pump. Polyethylene tubes (PE, 0.75 mm ID, 25 cm long) were precoated with purified human von Willebrand factor (vWF), fibrinogen (Fb), fibronectin (Fn), immunoglobulin G (IgG), albumin (HSA) or plasma. Compared with uncoated PE, platelet deposition increased after precoating with vWF, Fb or Fn, and decreased by pre adsorbed IgG, HSA or plasma. Platelet deposition was positively correlated with shear rate only on surfaces precoated with vWF, Fb or Fn. Scanning electron microscopy showed platelet aggregates on IgG—coated PE, whereas on all other surfaces single adherent platelets were observed. Complete platelet spreading was only observed after precoating with Fn. In contrast with PE coated with vWF, Fb or Fn, platelet adhesion on uncoated PE did not increase further after 5 minutes of perfusion probably due to passivation of the surface by albumin present in the perfusate. This could be overcome by addition of Fb to the perfusate. Perfusates prepared in this way were used for studying the effect of human endothelial cell (HEC) coverage on platelet deposition. HEC were seeded at different densities in PE tubes precoated with partially purified Fn. Platelet deposition decreased with 2increasing HEC coverage, and was negligible at 60,000 HEC/cm . Our results indicate the applicability of this perfusion model for the in vitro testing of artificial surface thrombogenicity.

Full textAbstract:
Three Layer Polyethylene (3LPE) coating for onshore pipelines have been used in India since the early 1980’s and have reached a level of maturity. The combination of Gas barrier by FBE layer and moisture barrier with mechanical and UV protection by black PE layer makes it better than either standalone FBE or 2LPE coatings. Further developments in PE materials makes 3LPE coating suitable for a design temperature range of −50°C to +90°C which practically covers all the onshore Oil pipelines in all geographies with excellent outdoor weathering resistance. It has also been possible to provide end-to-end protection with new PO Melt film technology that can give “factory applied” quality girth weld coating on site with complete fusion of girth weld coating with the parent coating, making it a hermetically sealed pipeline. This paper also discusses couple of the failure and success stories of 3LPE coating and their analysis.

Full textAbstract:
Defect classification is the basis of defect safety assessment because defects of different types can lead to failure in different forms. However, the identification of defect type has long been a critical issue in ultrasonic inspection. Wave acoustic was applied in this study to investigate the sound scattering of metal wires in polyethylene (PE), which provided theoretical support for ultrasonic feature extraction. A method of defect recognition for PE electro-fusion (EF) joints was proposed based on pattern recognition of ultrasonic inspection images. According to location, shape, signal intensity, and cluster conditions, typical defects of EF joints of PE pipes were distinguished and identified in phased array ultrasonic images. Furthermore, an automatic defect recognition software was designed based on the proposed approach; the software was improved and verified through defect inspection and identification experiments. Results showed that accuracy can reach 80% for joints with complex defects and 100% for those with single defects.

Full textAbstract:
The overall objective was to understand the cloud flocculation of citrus juice by characterization of the interactions between proteins and pectins, and to determine the role of PE isozymes in catalyzing this phenomenon. Specific objectives were to: 1. identify/characterize cloud-proteins in relation to their coagulable properties and affinity to pectins; 2. to determine structural changes of PME and other proteins induced by cation/pectin interactions; 3. localize cloud proteins, PME and bound protein/pectates in unheated and pasteurized juices; 4. to create "sensitized" pectins and determine their effect on clarification. The original objectives were not changed but the methods and approach were modified due to specific research requirements. Two i postulates were: 1. there is a specific interaction of cloud proteins with de-esterified regions of ! pectin and this contributes to cloud loss; 2. isozymes of pectin-methyl-esterase (PME) vary in efficiency to create sensitized pectins. The appearance of citrus fruit juice is an important quality factor and is determined by the color and turbidity that .are conferred by the suspended particles, i.e., by the cloud and its homogeneity. Under some circumstances the cloud tend to flocculate and the juice clarifies. The accepted approach to explain the clarification is based on pectin demethoxylation by PME that promotes formation of Ca-pectate. Therefore, the juice includes immediate heat-inactivation upon ~ squeezing. Protein coagulation also promotes cloud instability of citrus fruit extracts. However, the clarification mechanism is not fully understood. Information accumulated from several laboratories indicates that clarification is a more complex process than can be explained by a single mechanism. The increasing trend to consume natural-fresh juice emphasizing the importance of the knowledge to assure homogeneity of fresh juice. The research included complementary directions: Conditions that induce cloud-instability of natural- juice [IL]. Evaluate purification schemes of protein [USA]. Identifications of proteins, pectin and neutral sugars ([IL]; Structure of the cloud components using light and electron microscopy and immuno-labeling of PME, high-methoxyl-pectin (HMP) and low-methoxyl-pectin (LMP); Molecular weight of calcium sensitized pectins [US]; Evaluation of the products of PME activity [US]. Fractions and size distribution and cloud components [IL-US]. The optimal pH activity of PME is 7 and the flocculation pH of the cloud is 3-4. Thus, the c roles of PME, proteins and pectins in the cloud instability, were studied in pH ranges of 2- 7. The experiments led to establish firstly repeatable simulate conditions for cloud instability [IL]. Thermostable PME (TS-PE) known to induce cloud instability, but also thermolabile forms of PME (TL-PE) caused clarification, most likely due to the formation and dissolution of inactive :. PE-pectin complexes and displacement of a protective colloid from the cloud surface [US]. Furthermore, elimination of non-PME protein increases TS-PE activity, indicating that non-PME proteins moderate PME activity [US]. Other experiments Concomitantly with the study of the PME activity but promotes the association of cloud-proteins to pectin.

Full textAbstract:
The U.S. team studied the role of cations and pH on thermolabile (TL-PE) and thermostable (TS-PE), permeation in ultrafiltration (UF) membranes, affinity to ion exchange membranes, mechanism of cation and pH activation, and effect on PE stability. An optimum pH and cation concentration exists for activity and UF permeation, which is specific for each cation type. Incomplete release of PE from a pectin complex resulted in low PE binding to cationic and anionic membranes. Incubation of PE at low pH increases the surface hydrophobicity, especially TL-PE, but the secondary structure of TL-PE is not greatly affected. The Israeli team showed that stable cloud colloidal constituents flocculate following the conversion of soluble to insoluble biopolymers. First, formation of pectic acid by pectinesterase activity is followed by the formation of calcium pectate gel. This process initiates a myriad of poorly defined reactions that result in juice clarification. Second, protein coagulation by heat resulted in flocculation of proteinacous bound cloud constituents, particularly after enzymatic pectin degradation. Pectinesterase activity is proposed to be an indirect cause for clarification; whereas binding of cloud constituents is the primary event in clarification by pectate gel and coagulated proteins. Understanding the mechanism of interaction of protein and pectic polymers is key to understanding cloud instability. Based on the above, it was hypothesized that the structure of pectin-protein coagulates plays a key role in cloud instability.

Full textAbstract:
Structured financing solutions encompass a range of investment approaches that provide liquidity to investors without the need for a traditional equity exit event, such as a strategic sale, sale to another financial investor, or public market listing. Structuring mechanisms across the debt-to-equity spectrum determine the exit terms of the deal, therefore providing considerable downside protection to investors. Structured financing solutions are an incipient but increasingly important set of tools for investors active in Latin America to address the financing gap for companies that lack access to bank financing and are not attractive targets for traditional PE and VC players. Many investors employing these strategies are in an experimental phase, reporting new lessons learned with each deal completed. Impact investors have been among the top drivers of these structuring innovations, as they have grappled with the additional limitations associated with the straight equity model for environmental or social enterprises. However, the use of structured financing is by no means restricted to the impact investing space. Fund managers have invested USD4b in private credit deals in Latin America since 2018, more than the previous ten years combined. PE and VC investors have also increasingly employed quasi-equity and debt instruments. ACON Investments, for example, has employed mezzanine structures in several deals from its latest funds. Brazil-focused venture capital firm SP Ventures has recently begun investing from its debut venture debt fund. Growing experimentation by fund managers demonstrates the opportunity for investors across ticket sizes, strategies, and the impact-to-commercial spectrum. The structures discussed and the case studies highlighted in this report contain some of the major lessons applicable to a wide group of private capital investors in Latin America targeting certain and timely exits with consistent returns.
