1. Toxicity of Drilling Waste from Oil Wells on Oligochaeta
ABSTRACT The most abundant and critical elements in residues from well drilling and prospecting are barium and sodium. Ecotoxicological tests have been used to evaluate the toxicity caused by toxic substances present in the soil. The objective of the present study was to verify the effect of the application of drilling residue from oil wells on Oligochaeta

2. Methods of Hearing Preservation during Cochlear Implantation
Abstract Introduction Recent advances in surgical techniques and electrode design have made residual hearing preservation during cochlear implantation (CI) possible, achievable, and desirable. Objectives The objective of this study was to review the literature regarding methods used for hearing preservation during CI surgery. Data Synthesis We performe

3. Estimating extent and properties of blast-damaged zone around underground excavations
Abstract A common technique in hard rock tunneling, and underground excavation in general, is drilling and blasting. This method of excavation assumes that damage will be done to the surrounding rock mass depending on its quality. Herein is a proposal for how to estimate blast-damaged zone extent and shape, and how to quantify rock mass properties in this zo

4. Efeito do dano físico sobre o metabolismo de folhas de taioba, Xanthosoma sagittifolium (L.) Schott / Effects of wounding on the metabolism of tannia leaves, Xanthosoma sagittifolium (L.) Schott
Vegetables like leaves of tannia are subject to various factors which cause deterioration. Among these factors, mechanical damage triggers a series of physiological responses that occur at the site of the injury and surrounding tissues. The objective of this study was to evaluate the physiological responses of tannia leaves mechanical damaging, and whether t

5. Estudo sobre a furação de compósito de resina epóxi reforçado com fibras de vidro
The technological development has allowed the manufacture of sophisticated goods, leading to the pursuit of materials able to satisfactorily fulfill these requirements. Materials such as traditional metals, polymers and ceramics are still widely employed; however, they have been increasingly replaced by composite materials, which must be processed to the fin

7. MODELO ESTOCÁSTICO PARA A EXCLUSÃO PELO TAMANHO DURANTE O TRANSPORTE DE SUSPENSÕES PARTICULADAS EM MEIOS POROSOS / STOCHASTIC MODEL FOR SIZE EXCLUSION MECHANISM DURING SUSPENDED PARTICLE SUSPENSION TRANSPORT IN POROUS MEDIUM
Deep bed filtration of water with particles occurs in several industrial and environmental processes like water filtration and soil contamination. In petroleum industry, deep bed filtration occurs near to injection wells during water injection, causing injectivity reduction. It also takes place during well drilling, sand production control, produced water di

8. Early Experience with Biodegradable Implants in Pediatric Patients
We retrospectively studied nine children and adolescents with congenital malformations, large reconstruction after tumor excision, fractures and osteotomies of the upper extremity, and hand trauma with bone and soft tissue defects treated by internal synthesis using a biocopolymer of L- and DL-stereoisomers of lactic acid polymers and trimethylenecarbonate.
