In Julstar Pty Ltd v Lynch Morgan Lawyers [2012] QDC 272 Dorney QC DCJ considered whether an applicant for an assessment of all or part of their costs under s 335 of the Legal Profession Act 2007 (Qld) (LPA) must provide grounds on which they dispute the amount of the costs charged or their liability to pay them. His Honour also made an order for inspection of the solicitor’s file, despite a claimed lien for unpaid fees.

The question ‘is the planet full?’ is not new but it needs a critical assessment to provide a good answer. Obviously, the capacity of the planet should be evaluated in relation to the size and distribution of its human population and how relevant resources of the planet are used and managed. When we are discussing human population and resource management, multidimensional issues such as welfare, technologies and social changes are essential...

Objective 1. Measure spatial and temporal trawl frequency of scallop grounds using VMS data. This will provide a relative measure of how often individual undersized scallops are caught and put through a tumbler 2. Estimate discard mortality and growth rates for saucer scallops using cage experiments. 3. Evaluate the current management measures, in particular the seasonal closure, rotational closure and seasonally varying minimum legal sizes using stock assessment and management modeling models. Recommend optimal range of management measures to ensure long-term viability and value of the Scallop fishery based on a formal management strategy evaluation. Outcomes acheived to date: 1. Improved understanding of the survival rates of discarded sub-legal scallops; 2. Preliminary von Bertalanffy growth parameters using data from tagged-and-released scallops; 3. Changing trends in vessels and fishing gear used in the Queensland scallop fishery and their effect on scallop catch rates over time using standardised catch rates quantified; 4. Increases in fishing power of vessels operating in the Queensland scallop fishery quantified; 5. Trawl intensity mapped and quantified for all Scallop Replenishment Areas; 6. Harvest Strategy Evaluations completed.

A Subcomissão do Sistema Financeiro da Assembleia Nacional Constituinte (ANC) recebeu Marcos Freire, Presidente da Caixa Econômica Federal (CEF) e Camilo Calazans, Presidente do Banco do Brasil, que apoiam o destino social para a poupança e pedem o fortalecimento de bancos sociais. A Subcomissão também recebeu Dejandir Dom Pasquale, Presidente do Banco Nacional de Crédito Cooperativo (BNCC) que sugeriu a criação de cooperativas de crédito para os trabalhadores, favorecendo o pequeno e o micro produtor. A Subcomissão do Poder Judiciário e do Ministério Público ouviu os especialistas em direito José Lamartine, Luiz Pinto Ferreira e Roberto de Oliveira Santos que propuseram a criação de uma corte constitucional visando a correta interpretação da Constituição. A Subcomissão dos Negros, Populações Indígenas, Pessoas Deficientes e Minorias recebe documento das Associações dos Pais e Amigos do Excepcionais (APAES) e da Sociedade Pestalozzi pedindo proteção especial para as pessoas deficientes.

O Substitutivo nº 2 estabelece que as jazidas e recursos minerais sejam bens da União. O aproveitamento, a lavra e a pesquisa dos minérios somente poderão ser realizados por empresas nacionais com concessão do Governo Federal. A Deputada Raquel Cândido (DMDP-RO) defende que 50% da matéria-prima sejam industrializadas no local da jazida. Constituintes também reivindicam a promoção e desenvolvimento social dos garimpeiros. O Deputado Ademir Andrade (PMDB-PA) defende a criação de cooperativas no garimpo e a permanência dos garimpeiros nas jazidas onde já trabalham. A Comissão de Sistematização rejeita a proposta de pluralidade sindical. Aprovado o destaque do Deputado Geraldo Campos (PMDB-DF) que não permite a criação de mais de um sindicato por categoria profissional ou econômica na mesma base territorial. O Partido dos Trabalhadores (PT) vota contrário ao destaque. O Deputado Luís Inácio Lula da Silva (PT-SP) propõe outro destaque mantendo a liberdade sindical. O PT também protesta contra o imposto sindical. O Deputado Geraldo Campos (PMDB-DF) defende, mais uma vez, a unicidade do sindicato. O Deputado José Genuíno (PT-SP) critica o destaque aprovado. O Deputado Vivaldo Barbosa (PDT-RJ) enfatiza que a aprovação do destaque é um avanço por desvincular os sindicatos ao Estado.

The extraction and stripping kinetics of yttrium(III) with bis(2,4,4-trimethylpentyl) phosphinic acid (Cyanex 272, HA) dissolved in heptane as an acid extractant have been investigated by constant interfacial cell with laminar flow. The experimental hydrodynamic conditions have been chosen so that the contribution of diffusion to the measured rate of reaction is minimized. The plot of interfacial area on the rate has shown a linear relationship, which makes the interface the most probable local for the chemical reactions. At the same time, the extraction thermodynamic and kinetic methods are compared to determine the equilibrium extraction constant. A rate equation and the rate-determining step of the extraction and stripping of yttrium(III) have also been obtained, respectively.

Studies have been made on the kinetics of ytterbium(III) with bis-(2,4,4-trimethylpentyl) phosphinic acid (Cyanex 272, HA) in n-heptane using a constant interfacial cell with laminar flow. The stiochiometry and the equilibrium constant of the extracted complex formation reaction between Yb3+ and Cyanex 272 are determined. The extraction rate is dependent of the stirring rate. This fact together with the Ea value suggests that the mass transfer process is a mixed chemical reaction-diffusion controlled at lower temperature, whereas it is entirely diffusion controlled at higher temperature. The rate equations for the ytterbium extraction with Cyanex 272 have been obtained. The rate-determining step is also made by predictions derived from interfacial reaction models, and through the approximate solutions of the flux equation, diffusion parameters and thickness of the diffusion film have been calculated.

The yttrium(III) extraction kinetics and mechanism with bis-(2,4,4-trimethyl-pentyl) phosphinic acid (Cyanex 272, HA) dissolved in heptane have been investigated by constant interfacial cell with laminar flow. The data has been analyzed in terms of pseudo-first order constants. Studies on the effects of stirring rate, temperature, acidity in aqueous phase, and extractant concentration on the extraction rate show that the extraction regime is dependent on the extraction conditions. The plot of interfacial area on the rate has shown a linear relationship. This fact together with the strong surface activity of Cyanex 272 at heptane-water interfaces has made the interface the most probable location for the chemical reactions. The forward, reverse rate equations and extraction rate constant for the yttrium extraction with Cyanex 272 have been obtained under the experimental conditions. The rate-determining step has been also predicted from interfacial reaction models. The predictions have been found to be in good agreement with the rate equations obtained from experimental data, confirming the basic assumption that the chemical reaction is located at the liquid-liquid interface.

Kinetics and mechanism of stripping of yttrium(III) previously extracted by mixtures of bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272, HA), and 2-ethylhexyl phosphonic acid mono-2-ethylhexl ester (P507, HB) dissolved in heptane have been investigated by constant interfacial-area cell by laminar flow. The corresponding equilibrium stripping equation and equilibrium constant were obtained. The studies of effects of the stirring rate and temperature on the stripping rate show that the stripping regime is dependent on the stripping conditions. The plot of interfacial area on the rate has shown a linear relationship. This fact together with the strong surface activity of mixtures of Cyanex 272 and P507 at heptane-water interfaces makes the interface the most probable locale for the chemical reactions. The stripping rate constant is obtained, and the value is compared with that of the system with Cyanex 272 and P507 alone. It is concluded that the stripping ability with the mixtures is easier than that of P507 due to lower the activation energy of the mixtures. The stripping rate equation has also been obtained, and the rate-determining steps are the two-step interfacial chemical reactions as predicted from interfacial reaction models.
