Life cycle assessment (LCA) methods and tools are increasingly being taught in university courses. Students are learning the concepts and applications of process-based LCA, input−output-based LCA, and hybrid methods. Here, we describe a classroom simulation to introduce students to an economic input−output life cycle assessment (EIO-LCA) method. The simulation uses a simplified four-industry ec...

Three young children with anomalous origin of the left coronary artery (LCA) from the pulmonary artery were studied by two-dimensional echocardiography. The LCA was shown to be in confluence with the left posterior aspect of th pulmonary artery root in the two patients studied preoperatively. In one of these patients, and in another patient 2 years after surgery, studied after direct surgical i...

the spanish turbot aquaculture sector holds a top position in the international market. thisactivity is mainly developed along the galician coast (nw spain). this article evaluates the environmentalperformance of galician turbot aquaculture according to the life cycle assessment (lca) methodology.previously, on account of the expected relevance of feed for aquaculture, marine aquafeed productio...

Today, along with the increasing environmental awareness in the politic, public and industries, the demand on environmentally friendly products and technologies has been increasing. Therefore within the research and development of a product or technology in industries as well as in national or international funded R&D activities the method of Life Cycle Assessment (LCA) is often implemented in ...

Bile acids are steroid detergents that are toxic to mammalian cells at high concentrations; increased exposure to these steroids is pertinent in the pathogenesis of cholestatic disease and colon cancer. Understanding the mechanisms of bile acid toxicity and apoptosis, which could include nonspecific detergent effects and/or specific receptor activation, has potential therapeutic significance. I...

In this paper we seek to describe the structure of self-dual torsion-free LCA groups. We first present a proof of the structure theorem of self-dual torsion-free metric LCA groups. Then we generalize the structure theorem to a larger class of selfdual torsion-free LCA groups. We also give a characterization of torsion-free divisible LCA groups. Consequently, a complete classification of self-du...

Littoral cell angioma (LCA) is a rare benign tumour of the spleen. We describe a patient with aplastic anaemia who, following multiple treatments with rabbit and horse Anti-Thymocyte Globulin and anabolic steroids developed marked splenomegaly and hypersplenism. LCA was diagnosed post splenectomy. This is the first case of LCA associated with aplastic anaemia and its treatment.

Longitudinal Chromatic Aberration (LCA) influences the optical quality of the eye. However, the reported LCA varies across studies, likely associated to differences in the measurement techniques. We present LCA measured in subjects using wavefront sensing, double-pass retinal images, and psychophysical methods with a custom-developed polychromatic Adaptive Optics system in a wide spectral range...

PURPOSE To test the efficiency of a microarray chip as a diagnostic tool in a cohort of northwestern European patients with Leber congenital amaurosis (LCA) and to perform a genotype-phenotype analysis in patients in whom pathologic mutations were identified. METHODS DNAs from 58 patients with LCA were analyzed using a microarray chip containing previously identified disease-associated sequen...
