Variáveis que afetam o procedimento de colagem direta ortodôntica: procedimentos clinicos

Direct bonding of orthodontics attachments to the teeth or restoration has become a routine in fixed appliance therapy. The technique used seems to be simple, but meticulous attention to detail and steps, a thorough understanding of factors involved are needed to ensure a successful outcome into different surfaces. It is the purpose of this article to review concerning aspects to orthodontic bonding in enamel and restorations fabricated from different materials; affording assistance to the reader wiser accomplishment and successful procedure.

Otimização de procedimento para a determinação de maganês em amplo intervalo de concentração por espectrometria de absorção atômica em chama com fonte contínua e alta resolução

This work describes instrumental strategies for the determination of Mn in a wide range concentration by high-resolution continuum source flame atomic absorption spectrometry technique (HR-CS F AAS) by means of different atomic lines (primary at 279.482 nm, secondary at 403.075 nm and alternative at 209.250 nm). These lines provided complementary concentration intervals, and large sample dilutions became unnecessary. The proposed method was applied to tap water, metal alloy certified material and foliar fertilizer. Accuracy for secondary line were evaluated by tests of significance (t Student test) with reference materials from the Institute of Technological Research of São Paulo, and the results were in agreement at the 95% confidence level. For primary and alternative lines, recovery is were in the 84-116% range and the RSD were 6.1% for all wavelengths. Analytical curves in the 0.1 - 2.0 mg L-1 (279.482 nm), 2.0 - 25 mg L-1 (403.075 nm), 25 - 500 mg L-1 (209.250 nm) intervals were obtained with linear correlation coefficient better than 0.9991. The detection limits were 3.3x10-3 mg L-1 (279.482 nm), 7.4 x 10-3 mg L-1 (403.075 nm), 3.9 mg L- 1 (209.250 nm). The found Mn concentrations were < 3.3x10-3 mg L-1 (tap water), 1.00 ± 0.04 (% m/m) (alloy IPT 25), 7235 ± 175 mg L-1 (foliar fertilizer 1), 4990 ± 132 mg L-1 (foliar fertilizer 2). A method was developed to detect interference of Fe in the Mn primary line (279.482 nm) using the ratio of absorbances of other lines of the triplet (279.827 nm and 280,108 nm).

Construção de índice percentual de “status” de desenvolvimento sus-tentável de assentamentos rurais utilizando procedimento estatísti-co multivariado

The objective of the present work is the construction of percentual indexes of sustainable development "Status" - PIDSD (%) aiming to order and classify the rural settlements, considering agricultural, socioeconomic and environmental aspects, in order to diagnose their sustainable reality. This way, we considered multivariate statistical procedure to establish analytical descriptors - indexes - like the principal components technique (CP). The CP technique was used in a matrix formed by 47 variables observed in 50 rural settlements, distributed in seven different regions of the state of Mato Grosso, obtained from diagnostics, provided by "Mato-Grossense" Enterprise of Research, Assistance and Rural Extension S/A - EMPAER - MT, in order to obtain the indexes used in the construction of PIDSD (%). The settlements with higher PIDSD (%) were considered "higher potential" or "higher sustainable" in relation to the analyzed variables, making the establishment of assistance strategies and cooperation possible, allowing the government and civil society in general, to improve those with worse results ("lower potential" or "lower sustainable"), and search for ways to strengthen and multiply the results of the "higher potential" settlements. Vale do Seringal settlement had the best conditions in relation to the variables, mainly those of higher weigh and was considered the one with "higher potential". São Sebastião had the worst conditions and was considered "lower potential".

Procedimento para homologação de sistemas ecoeficientes para obtenção de créditos de carbono

This paper deals with the homologation process for obtaining carbon credits through the Clean Development Mechanism (CDM), that regulates the greenhouse gases reductions under the rules of the Kyoto Protocol. The CDM evaluates projects through a project cycle, which begins with the preparation of the Project Design Document (PDD) until the project certification to receive Certified Emission Reductions (CERs), popularly known as carbon credits. This study analyzed the implementation of the system Burner Recorder System for Low Flows of Biogas (QRBBV), developed by Marcelino Junior & Godoy (2009), in an eco-friendly wastewater treatment mini-plant (miniEETERA), built at the site of UNESP - Guaratinguetá SP. The QRBBV system is low cost and high reliability, developed to burn the methane generated at sites of low and variable production of biogas, which is not economically justified their energy recovery. Currently, almost all wastewater generated at the site of the campus is being treated by miniEETERA and, as a result, the biogas originated by this activity is being released into the atmosphere. Therefore, the project activity aims to capture and burn the biogas generated by miniEETERA, reducing the negative effects caused by the methane emissions into the atmosphere and, thus, claim to receive carbon credits. This work aimed to demonstrate the project applicability under CDM through the study and preparation of the PDD, as well as an analysis of the entire project cycle required for homologation. The result of the work obtained an estimate of only 20 CERs per year and proved to be economically unviable for approval through the CDM, since the spending with the approval process would not be compensated with the sale of CERs, mainly due the low carbon price in the world market. From an environmental standpoint, the project is perfectly... (Complete abstract click electronic access below)
