O Contributo de Sines na Eclosão de um Cluster Regional

O desenho daquilo que é traçado neste artigo não se confina ao estudo do porto de Sines numa lógica de pura gestão portuária, nem tão só à observação decomposta dos fluxos originados pelo chamado complexo industrial, dado que até ao presente, a história económica se encarregou de proceder a essa análise anatómica estrutural. Aquilo que se preconiza extravasa o mero circunstancialismo ou o somatório das partes e...

EPIDURAL BLOOD PATCH IN SPONTANEOUS INTRACRANIAL HYPOTENSION

Background: Spontaneous Intracranial Hypotension (SIH) is a rare condition caused by a spinal cerebrospinal fluid (CSF) leak. It is usually described as an orthostatic headache, frequently associated with neck pain, nausea, vomiting, diplopia, blurred vision and distorted hearing. Initial treatment consists of bed rest, fluid supplementation, caffeine and analgesics. If conservative treatment fails, an epidural...

FBG sensors application for residual stress measurement using the hole drilling...

This work focus on the development of a new sensor for residual stress measurement using fiber optic Bragg sensors. A known stress field was induced on a specimen and results obtained from both the fiber optic Bragg sensors rosette and traditional electrical strain rosette were compared. Also a FEM model was used to confirm the obtained results.

Molecular mechanisms beyond glucose transport in diabetes-related male infertility

Diabetes mellitus (DM) is one of the greatest public health threats in modern societies. Although during a few years it was suggested that DM had no significant effect in male reproductive function, this view has been challenged in recent years. The increasing incidence of DM worldwide will inevitably result in a higher prevalence of this pathology in men of reproductive age and subfertility or infertility asso...

New methodology to measure residual stresses based on FBG sensors

Residual stresses are locked-in stresses which exist in a structural part without the application of any service or other external loads. The effects of residual stress may be either beneficial or detrimental, depending upon the magnitude, sign, and distribution of the stress with respect to the in service applied loads. In most cases, residual stresses arise from the production process. In order to measure re...

Surgical complications in 2000 renal transplants

INTRODUCTION: Renal transplantation is the best treatment for end-stage renal disease. In the last years, we have seen improvements in immunosuppressive treatment, which have allowed patients to experience a better quality of life and graft survival. Nevertheless, surgical complications remain important problems that increase morbidity, mortality, costs, and hospitalization. Our purpose was to evaluate surgical...

IgE cross-reactivity between Lolium multiflorum and commercial grass pollen all...

Lolium multiflorum (Lm) grass pollen is the major cause of pollinosis in Southern Brazil. The objectives of this study were to investigate immunodominant components of Lm pollen allergens and the cross-reactivity of IgE with commercial grass pollen allergen extracts. Thirty-eight serum samples from patients with seasonal allergic rhinitis (SAR), 35 serum samples from patients with perennial allergic rhinitis (P...

The contour method for residual stress determination applied to an AA6082-T6 fr...

Residual stresses parallel to the welding direction on a cross-section of a 3 mm thick friction stir butt-welded aluminium alloy AA6082-T6 plate were determined using the contour method. This is a destructive relaxation based measurement technique capable of determining the full- eld residual stresses perpendicular to a plane of interest. A wire electro discharge machining cut was performed revealing the plane ...
