1. In vitro Monitoring of Macro and Microelements in Multimineral Preparations across Dissolution Profiles by Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES)
In this study, inductively coupled plasma optical emission spectrometry (ICP OES) was used for multi-element analysis in five multimineral preparations from a dissolution test, in accordance with the United States Pharmacopeia (USP 34 method): apparatus 1, 75 rpm and 900 mL of 0.1 mol L-1 HCl. Element releases in all samples (minimum-maximum in %) were: Ca (

2. Multielement Determination of Macro and Micro Contents in Medicinal Plants and Phytomedicines from Brazil by ICP OES
In this study, the elemental composition of nine medicinal plants and phytomedicines was evaluated by using axial view inductively coupled plasma optical emission spectrometry (ICP OES) after three digestion procedures: dry ashing (DA) and two wet digestions with a mineral acid (HNO3/H2O2) mixture on a conventional hot plate (CD), besides microwave digestion

3. Antimicrobial activity of ozone and NaF-chlorhexidine on early childhood caries
Abstract An early childhood carie (ECC) is an extremely destructive form of tooth decay. The aim of this study was to investigate the action of ozone (O3), and the association of sodium fluoride (NaF) with chlorhexidine (CHX) on bacteria related to ECC. Overnight culture of the bacteria was performed. On exponential phase the suspension was adjusted (101-108

4. Enriched environment contributes to recovery of visual acuity and increases perineuronal nets in monocular-deprived animals
The aim of the present study was to analyze the influence of enriched environment on the distribution of perineuronal nets (PNNs) using a stereogically based unbiased protocol and visual acuity in adult Swiss albino mice that underwent monocular deprivation during the critical period of postnatal development. Eight female Swiss albino mice were monocular dep

5. DESENVOLVIMENTO DE TRANSDUTORES A FIBRA ÓPTICA PARA COMPLETAÇÃO INTELIGENTE DE POÇOS / DEVELOPMENT OF OPTICAL FIBER TRANSDUCERS FOR INTELLIGENT WELL COMPLETION
Optical fibers are finding a growing range of new applications in the petroleum industry, which include, not only those already well established in telecommunications, but also in novel sensing technologies. Possibility of dense multiplexing, continuous distributed measurements, long distances between measurement points and electronic circuits, and explosion

6. PREVENÇÃO DE INCRUSTAÇÕES INORGÂNICAS NA EXPLORAÇÃO PETROLÍFERA OFF-SHORE: ASPECTOS ANALÍTICOS E APLICAÇÕES DO INIBIDOR PPCA / PREVENTION OF INORGANIC SCALE FORMATION IN OFF-SHORE OIL EXPLORATION: APPLICATIONS OF THE PPCA INHIBITOR
In the present study, a system was developed for the automatized pretreatment of the inhibitor phosphinocarboxilic acid (PPCA) used during off-shore oil exploration to minimize the occurrence of inorganic scale formation. The components of the system used are: 3, 4 or 6 way solenoid valves with Teflon body, a home-made electronic circuit for activation of th

7. MULTIPLEXAÇÃO ÓPTICA NO DOMÍNIO DO TEMPO EM SISTEMA STM-16, STM-64, STM-256 / TIME-DOMAIN OPTICAL MULTIPLEXING IN STM-16, STM-64 AND STM-256 SYSTEMS
Este trabalho tem como foco o up-grade da taxa de bits em enlaces ópticos através da tecnologia OTDM. Os sistemas analisados contemplam os up-grades das taxas de 2,48 Gbps para 10 Gbps e também da taxa de 10 Gbps para 40 Gbps. Para tal, foram introduzidos módulos de transmissão e recepção, capazes de utilizar arquiteturas quase totalmente ópticas. É

8. ESTUDO E IMPLEMENTAÇÃO DE RECUPERAÇÃO DE RELÓGIO POR PROCESSO ÓPTICO / IMPLEMENTATION OF ALL OPTICAL CLOCK VECOVERY CIRCUITS
Today bit-rates increase quickly in optical communications sustems. New technologies and fabrication process discovers are fundamental to the development of several devices in the transmission and reception systems. Soon, optical communication systems working in 100Gbits/s will be a reality. This work intends to solve the problem of clock recovery in high ca

9. Recristalização das ligas supercondutoras do sistema Nb-Ti
Multifilamentary cables of Nb-Ti alloys have been used mainly in superconducting engines and devices. These alloys have high ductility and their final most important superconducting properties can be established by suitable metallurgical procedures. In this work the influence of the microstructural characteristics on the superconducting properties and of the

10. A new method to study shape recovery of red blood cells using multiple optical trapping.
In this new method for studying the shape recovery of deformed red blood cells, three optical traps ("optical tweezers") induce a parachute-shaped red cell deformation, which is comparable to the deformation in small capillaries. The shape recovery is recorded, and a relaxation time is obtained for each individual red blood cell. The sensitivity of this tech

11. Serological follow-up after treatment of patients with erythema migrans and neuroborreliosis.
To investigate the duration and kinetics of immunoglobulin M (IgM) and IgG antibodies against Borrelia burgdorferi in serum after treatment of Lyme borreliosis, consecutive serum samples from 30 seropositive patients with erythema migrans and 91 seropositive patients with neuroborreliosis were analyzed with a capture IgM enzyme-linked immunosorbent assay (EL

12. Membrane knobs are required for the microcirculatory obstruction induced by Plasmodium falciparum-infected erythrocytes.
We have studied the pathophysiology of the vascular obstruction induced by Plasmodium falciparum-parasitized erythrocytes with the use of an ex vivo microcirculatory preparation perfused with red cells infected with knobless and knobby clones of the FCR-3 strain. We find that parasitized erythrocyte membrane knobs are indispensable for the generation of the
