Continuous flow injection reaction/stopped flow detection using derivative spectrophotometry. Determination of cobalt and iron in mixtures
(MARCEL DEKKER INC, 1996)
A continuous flow injection reaction-stopped flow detection method using derivative spectrophotometry was developed for the determination of cobalt and iron in mixtures. A conventional two-channel flow injection manifold ...
An Adaptive Mechanism to Protect Databases against SQL Injection
(2015-07-01)
The purpose of this article is to present an adaptive and intelligent mechanism that can handle SQL injection attacks. This proposal focuses on integrating a case-based reasoning (CBR) mechanism with a neural network. The ...
Are intra-articular injections of hyaluronic acid effective for the treatment of temporomandibular disorders? A systematic review
(2016-12-01)
This systematic review aimed to investigate whether intra-articular injections of hyaluronic acid (HA) are better than other drugs used in temporomandibular joint arthrocentesis, for the improvement of temporomandibular ...
Injective Colorings with Arithmetic Constraints
(Springer, 2015)
An injective coloring of a graph is a vertex labeling such that two vertices sharing a common neighbor get different labels. In this work we introduce and study what we call additive colorings. An injective coloring of a ...
Thermal effects on stereolithography tools during injection moulding
(2004)
In this work, the changes to stereolithography (SL) resin mechanical properties during the injection moulding process were evaluated. A multi-impression SL mould was built and used to inject a series of small flat mouldings. ...
Estudo de caso: injeções de calda de cimento para impermeabilização e consolidação de fundação de barragem
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2022-03-31)
During the stage of the viability study for the implementation of Small Hydroelectric Power Plants, it is of fundamental importance to have knowledge about how it is composed and how the rock mass is presented, in the area ...
Single- versus double-injection costoclavicular block: a randomized comparison
(BMJ, 2020)
Background The costoclavicular approach targets the brachial plexus in the proximal infraclavicular fossa, where the lateral, medial, and posterior cords are tightly bundled together. This randomized trial compared single- ...
Recycling of Low-Value Hydrocarbon Cuts by Means of Multiple Injections to FCC Units
(American Chemical Society, 2002-11)
The upgrading of a visbreaker naphtha by recycling it into an FCC unit was studied following the approach of multiple injections (with the naphtha in the first one) using a laboratory riser simulator reactor and an ...
Impact properties and microhardness of double-gated glass-reinforced polypropylene injection moldings
(Wiley, 2009-08-10)
Injection moldings with weld lines were produced in glass reinforced polypropylene grades differing in filler content using a two-gated hot runner injection mold. The skin-core microstructure developed during injection ...
Polarization switching and hysteresis in vertical-cavity surface-emitting lasers subject to orthogonal optical injection
(Institute Of Electrical And Electronics Engineers, 2014)
We study polarization switching and hysteresis in a vertical-cavity surface-emitting laser (VCSEL) subject to an orthogonal optical injection, such that the polarization of the injected light is perpendicular to that of ...
