1. Physical Compatibility and Stability of Pesticide Mixtures at Different Spray Volumes
RESUMO: As informações disponíveis sobre compatibilidade física e estabilidade de misturas de agrotóxicos são escassas e muitas vezes divergentes. Esse conhecimento é de fundamental importância no sucesso de programas de controle de insetos-praga, doenças e plantas daninhas. Nesta pesquisa foi avaliada, em condições laboratoriais, a compatibilidad

2. Optimization of extraction process for efficient imino acids recovery and purification from low-value sea cucumber
Abstract For high recoveries and purities of L-proline (L-Pro) and L-hydroxyproline (L-Hyp) from the low-value sea cucumber Acaudina leucoprocta, the extraction process was systematically investigated and optimized. The results indicated that, in decoloration of A. leucoprocta hydrolysate, activated carbon powdered W660 was more suitable due to the low addit

3. Separation and pain perception of Elastomeric, Kesling and Kansal separators
Resumo Introdução: diversos tipos de separadores de dentes já foram descritos e seu uso, justificado na literatura. Porém, o separador ideal deve produzir uma força adequada para realizar a separação com o mínimo de dor e desconforto. Objetivo: o objetivo do presente estudo foi avaliar e comparar a separação ortodôntica obtida por meio de três

4. The Control of Asymmetric Rolling Missiles Based on Improved Trajectory Linearization Control Method
ABSTRACT According to motion characteristic of an asymmetric rolling missile with damage fin, a three-channel controlled model is established. The controller which is used to realize non-linear tracking and decoupling control of the roll and angle motion is introduced based on an improved trajectory linearization control method. The improved method is compos

5. Recovery of p-TBC from a butadiene washing stream in a pilot plant
Results obtained in a pilot-scale unit designed for COD removal and p-TBC (p-tert-butylcatechol) recovery from a butadiene washing stream (pH 14, 200,000 mg COD L-1, highly toxic) at a petrochemical industry are presented. By adding H3PO4, phase separation is achieved and p-TBC is successfully recovered (88 g L-1 of washing stream). Information (time for pha

6. Recent developments in superstatistics
We provide an overview on superstatistical techniques applied to complex systems with time scale separation. Three examples of recent applications are dealt with in somewhat more detail: the statistics of small-scale velocity differences in Lagrangian turbulence experiments, train delay statistics on the British rail network, and survival statistics of cance

7. Experimental purification of paclitaxel from a complex mixture of taxanes using a simulated moving bed
A laboratory-scale simulated moving bed (SMB) was designed and tested for the separation of paclitaxel, a powerful anti-cancer agent known as Taxol@, from impurities of a plant tissue culture (PTC) broth. The innovative strategy of a pseudo-binary model, where mixtures A and B were treated as single solutes A and B, was used in the linear standing wave analy

8. Tratamento de esgoto sanitário em um reator de leito expandido em escala plena, operado com regiões anaeróbia e aeróbia sobrepostas / Treatment of sanitary wastewater in a full scale expanded bed reactor, operated with overlap anaerobic and aerobic regions
This present research had as main objective the evaluation of the performance of a full scale expanded bed reactor (159.0 M POT.3), operated under anaerobic and overlapping anaerobic-aerobic, treating sanitary wastewater. As specific objectives, it was evaluated using commercial sand to complement the bed of particles and distribution of material support alo

9. Unusual domain growth behavior in the compressible ising model
Large scale Monte Carlo simulations have been used to study long-time domain growth behavior in a compressible, two-dimensional Ising model undergoing phase separation. The system is quenched below the transition temperature from a random spin state, and we investigated the late-time domain size growth law, R(t) = A + Bt n. For "lattice mismatched" systems,

10. PreparaÃÃo e utilizaÃÃo de uma argila organofÃlica como adsorvente de Fenol
This research had as main objective the attainment of organophilic clay with capacity to promote the separation of phenol, found in effluent the watery ones of petrochemical industries. The experimental procedure objectifying the attainment of the organoclay was initiated by a treatment of natural clay with sodium carbonate. This treatment had as goal to int

11. Isomeric State Measurement System / Sistema para medida de estados isoméricos
A system, called SISMEI (Isomeric State Measurement System), was developed for the detection and measurement of isomeric states with half-lives in the range of 10 ns to 10 s without the use of a pulsed beam. This system mainly uses the technique of charged particles and -ray delayed coincidences. In SISMEI, the statistical background is reduced by the separa

12. ESTUDO DO CICLO DIÁRIO DA CAMADA LIMITE PLANETÁRIA ATRAVÉS DA SIMULAÇÃO DOS GRANDES TURBILHÕES / STUDY OF DAILY CYCLE OF PLANETARY BOUNDARY LAYER BY LARGE EDDY SIMULATION
The PBL is the region on the troposphere characterized by existence of turbulence (BUSINGER, 1981). Turbulent flow is that when the fluctuations of the variables that describe the flow are amplified in time and space (LANDAU; LIFSHITZ, 1959). The study of the planetary boundary layer (PBL) through the computational fluid dynamics, particularly the large eddi
