Novel catalyst systems based on Ni(II), Ti(IV), and Cr(III) complexes for oligo-and polymerization of ethylene

The complex of Brookhart Ni(α-diimine)Cl2 (1) (α-diimine = 1,4-bis(2,6- diisopropylphenyl)-acenaphthenediimine) has been characterized after impregnation on silica (S1) and MAO-modified silicas (4.0, 8.0 and 23.0 wts.% Al/SiO2 called S2, S3 and S4, respectively). The treatment of these heterogeneous systems with MAO produces some active catalysts for the polymerization of the ethylene. A high catalytic activity has been gotten while using the system supported 1/S3 (196 kg of PE/mol[Ni].h.atm; toluene, Al/Ni = 1000, 30ºC, 60 min and atmospheric pressure of ethylene). The effects of polymerization conditions have been tested with the catalyst supported in S2 and the best catalytic activity has been gotten with solvent hexane, MAO as cocatalyst, molar ratio Al/Ni of 1000 and to the temperature of 30°C (285 kg of PE/mol[Ni].h.atm). When the reaction has been driven according to the in situ methodology, the activity practically doubled and polymers showed some similar properties. Polymers products by the supported catalysts showed the absence of melting fusion, results similar to those gotten with the homogeneous systems by DSC analysis. But then, polymers gotten with the transplanted system present according to the GPC’s curves the polydispersity (MwD) varies between 1.7 and 7.0. A polyethylene blend (BPE/LPE) was prepared using the complex Ni(α-diimine)Cl2 (1) (α-diimine = 1,4-bis(2,6-diisopropylphenyl)-acenaphthenediimine) and {TpMs*}TiCl3 (2) (TpMs* = hydridobis(3-mesitylpyrazol-1-yl)(5-mesitylpyrazol-1-yl)) supported in situ on MAO-modified silica (4.0 wts. -% Al/SiO2, S2). Reactions of polymerization of ethylene have been executed in the toluene in two different temperatures (0 and 30°C), varying the molars fraction of nickel (xNi), and using MAO as external cocatalyst. To all temperatures, the activities show a linear variation tendency with xNi and indicate the absence of the effect synergic between the species of nickel and the titanium. The maximum of activity have been found at 0°C. The melting temperature for the blends of polyethylene produced at 0 °C decrease whereas xNi increases indicating a good compatibility between phases of the polyethylene gotten with the two catalysts. The melting temperature for the blends of polyethylene showed be depend on the order according to which catalysts have been supported on the MAO-modified silica. The initial immobilization of 1 on the support (2/1/S2) product of polymers with a melting temperature (Tm) lower to the one of the polymer gotten when the titanium has been supported inicially (1/2/S2). The observation of polyethylenes gotten with the two systems (2/1/S2 and 1/2/S2) by scanning electron microscopy (SEM) showed the spherical polymer formation showing that the spherical morphology of the support to been reproduced. Are described the synthesis, the characterization and the catalytic properties for the oligomerization of the ethylene of four organometallics compounds of CrIII with ligands ([bis[2-(3,5-dimethyl-1-pyrazolyl)ethyl]amine] chromium (III) chloride (3a), [bis[2-(3,5- dimethyl-l-pyrazolyl)ethyl]benzylamine] chromium (III) chloride (3b), [bis[2-(3,5-dimethyl-lpyrazolyl) ethyl]ether] chromiun(III)chloride (3c), [bis[2-(3-phenyl-lpyrazolyl) ethyl]ether]chromiun(III)chloride (3d)). In relation of the oligomerization, at exception made of the compounds 3a, all complex of the chromium showed be active after activation with MAO and the TOF gotten have one effect differentiated to those formed with CrCl3(thf)3. The coordination of a tridentate ligand on the metallic center doesn't provoke any considerable changes on the formation of the C4 and C6, but the amount of C8 are decrease and the C10 and C12+ have increased. The Polymers produced by the catalyst 3a to 3 and 20 bar of ethylene have, according to analyses by DSC, the temperatures of fusion of 133,8 and 136ºC respectively. It indicates that in the two cases the production of high density polyethylene. The molar mass, gotten by GPC, is 46647 g/mols with MwD = 2,4 (3 bar). The system 3c/MAO showed values of TOF, activity and selectivity to different α-olefins according to the pressure of ethylene uses. Himself that shown a big sensibility to the concentration of ethylene solubilized.

A politica fiscal no Brasil : limites e contradições : o caso do Estado do Espirito Santo

o estudo pretende contribuir para a análise da realidade brasileira, através do caso do Estado do Espírito Santo, no período compreendido entre 1946 a 1980, tentando demonstrar a dependência financeira dos governos estaduais refletida na perda de receitas próprias e da necessária autonomia para a sua utilização. Numa visão retrospect.iva observa-se uma excessiva tendência à centralização manifestada pelo federalismo brasileiro, principalmente, depois da Reforma Tribut.ária de 1967, que estabeleceu um rigoroso controle da União sobre as receitas tributárias e sobre a ação dos Estados- membros, reduzindo sua autonomia em matéria de legislação tributária. A centralização financeira e política fez com que os go- . , . vernos estaduais perdessem 8S prerrogativasanteriorrnente adquiridas e tivessem limitada sua autonomia em;matéria de politica fiscal. Tentou-se compensar a acentuada redução das receitas tributárias estaduais lnstituindo- se o mecanismo das transferências que, a despeito de suas funç5es redIstributi vas, impõe uma série de exig§ncias e determinações para a sua aplicação. A partir dessa constataç50 passa-se a analisar a política fiscal no Estado do Espírito Santo observando-se as administrações estaduais nesse período. Cheg~-se à conclusão de que as sucessivas crises financeiras ocorridas limitaram a formulação de uma política fiscal estadual. Com isso, constat3-se que os estados passaram a ser rneros agentes administrativos reproduzindo as decis5es maiores formuladas pelo governo federal. Em linhas gerais, tentou-se comprovar a dependência fi--

Análise do custo-aluno das creches municipais diretas do município de Santo André

O presente estudo tem como foco o levantamento e análise do custo-aluno das creches, primeira etapa da Educação Infantil, que compreende as crianças de 0 a 3 anos de idade. Ele responde à situação problema apresentada pela Secretaria de Educação do Município de Santo André (SP), caracterizada pela necessidade do aprimoramento da gestão dos recursos financeiros em um cenário de dificuldades orçamentárias e aumento de demanda. Foram selecionadas 12 unidades municipais da rede direta, com atendimento exclusivo a crianças nesta faixa etária. A metodologia utilizada teve como base a utilização do Sistema de Informações do Orçamento Público municipal, a partir do qual foram realizadas as consultas e definições dos componentes do custo do objeto em estudo, sendo que a metodologia de acumulação de custos utilizada foi o custeio por absorção. Adicionalmente, os autores analisaram os processos administrativos relacionados aos itens de custeio e realizaram entrevistas com os diversos atores envolvidos nos processos de gestão daquela e de outras secretarias, bem como acadêmicos dedicados ao estudo de custos no setor público, cujas experiências relatadas subsidiaram a pesquisa e as avaliações realizadas. O estudo apontou um custo-aluno médio de R$ 11.970,72 sendo que, para melhor análise dos resultados, as unidades escolares foram agrupadas em três categorias de acordo com o número de alunos: i) pequeno porte: com até 149 alunos (três unidades); ii) médio porte: entre 150 e 190 alunos (cinco unidades); e, iii) grande porte: com mais de 190 alunos (quatro unidades). A partir dessa divisão foi possível concluir que as creches de grande porte apresentaram vantagem comparativa em relação às demais, com custo-aluno médio de R$ 11.684,03, seguidas das creches de médio porte, R$ 11.751,46 e pelas unidades de pequeno porte, que apresentaram o custo-aluno de R$ 13.235,88, ou seja, 13,23% acima das escolas de grande porte. Esses resultados indicam a existência de ganhos de escalas de acordo com o porte da creche e pode subsidiar a tomada de decisão dos gestores para futuros projetos de expansão da rede pública de creches.

Absence of TGF-beta RII predicts bone and lung metastasis and is associated with poor prognosis in stage III breast tumors

In the case of operated breast cancer (BC), prognostic markers help to determine if the patient needs additional treatment and predictive markers help the clinician to decide which treatment to use. Thus, a better knowledge of known predictive and prognostic markers and the identification of new markers, may improve the treatment of BC patients. The transforming growth factor-beta type II receptor (TGF-beta RII), a main receptor of transforming growth factor beta pathway, is a potential new prognostic marker. The aims of the present study were to investigate both the predictive and prognostic impact of TGF-beta RII in BC samples. TGF-beta RII protein expression was evaluated using immunohistochemistry on a tissue microarray containing 110 TNM stage III BC samples obtained prior to doxorubicin-based neoadjuvant chemotherapy (NAC). Our results demonstrate that TGF-beta RII did not predict the response to NAC. on the other hand, an association between TGF-beta RII-negative tumor and higher risk of metastasis to lungs and bones was verified. TGF-beta RII negativity was an independent prognostic factor for decreased disease-free and overall survival.

Parasitismo natural de bufalinos em Botucatu, SP, Brasil: III. Dinâmica do parasitismo gastro-intestinal em vacas e suas crias

Gastro-intestinal parasitism of 24 buffalo cows before parturition, and post-parturition, their infection and that of their respective calves during the following 30 weeks were studied. Willis, Hoffmann and whenever possible, the modified Gordon & Whitlock techniques were used for fecal examinations. Toxocara vitulorum eggs were the earliest forms encountered in calves feces, as follows: during the 1st week after birth, 58.33% of the calves were positive, and in the 4th week, 100% of these animals were positive. Eggs of Strongyloides sp were in the 1st week after birth in two of the calves and in the 5th week, all for them were positive. The next parasites to appear were the Coccidia of which oocysts were detected in the feces of two calves in the 2nd week after birth, and 58.33% of the calves were positive for these in the 3rd week, and in the 6th week, all calves shed oocysts in their feces. on the other hand, eggs of Strongylids were the last forms to appear in calves feces. However, despite their sporadic appearance in the feces, eggs of these parasites were observed continuously from the 11th week onwards, and at this point, the percentage of positive samples began to increase to reach its peak. Relatively to adult animals, eggs of T. vitulorum were observed in the feces of 11 cows, one or twice at most; eggs of Strongyloides sp were seen only once in the feces of four buffalo cows and eggs of Strongylids in 21 out of 24 cows. Oocysts of Coccidia were observed in 16 cows. Mechanisms of infestation of calves with these parasites are discussed.

Intrusion of teeth with class III furcation: a clinical, histologic and histometric study in dogs

Aim: To assess orthodontic intrusion effects on periodontal tissues in dogs' pre-molars with class III furcations treated with open flap debridement (OFD) or with guided tissue regeneration (GTR) associated to bone autograft (BA).Material and Methods: Class III furcations were created in the pre-molars of seven mongrel dogs. After 75 days, teeth were randomly treated with OFD or GTR/BA. After 1 month, metallic crowns were assembled on pre-molars and connected apically to mini-implants by nickel-titanium springs. Teeth were randomly assigned to orthodontic intrusion (OFD+I and GTR/BA+I) groups or no movement (OFD and GTR/BA) groups. Dogs were sacrificed after 3 months of movement and 1 month retention.Results: All class III furcations were closed or reduced to class II or I in the intrusion groups, while 50% of the lesions in non-moved teeth remained unchanged. Intruded teeth presented higher probing depth and lower gingival marginal level than non-moved teeth (p < 0.01). Clinical attachment gain was reduced in the intrusion groups by the end of retention (p < 0.05). OFD+I presented smaller soft tissue area and larger bone tissue area than other groups (p < 0.05).Conclusion: Orthodontic intrusion with anchorage via mini-implants improved the healing of class III furcation defects after OFD in dogs. GTR/BA impaired those results.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)

New species of Ischnocnema (Anura, Brachycephalidae) from the atlantic rainforest of the state of Espirito Santo, Brazil.

We describe a new species of Ischnocnema from Santa Teresa, in the Atlantic Rainforest of the State of Espirito Santo, Brazil. Ischnocnema abdita sp. nov. is a member of the Ischnocnema lactea species series; it differs from other Ischnocnema mainly by presenting small size (adult male SVL 15.7 [plus or minus] 0.49 mm; range 15.0-16.8 mm); small discs on fingers I and II, and elliptical, wider than long, moderate sized discs on fingers III and IV; and finger I slightly smaller than finger II. The new species closely resembles Ischnocnema bolbodactyla, differing from it by presenting upper and lower margins of iris red in life; inguinal region with many yellow blotches in life; posterior region of belly and ventral surfaces of thighs, shanks, and feet roughly marbled with large pale yellow blotches; and hidden dorsal area of thighs dark brown with few large pale yellow blotches.
