Endometriosis: A Rare Cause of Large Bowel Obstruction.
Large bowel obstruction can result in significant morbidity and mortality, especially in cases of acute complete obstruction. There are many possible causes, the most common in adults being colorectal cancer. Endometriosis is a benign disease, and the most affected extragenital location is the bowel, especially the rectosigmoid junction. However, transmural involvement and acute occlusion are very rare events. We report an exceptional case of acute large bowel obstruction as the initial presentation of endometriosis. The differential diagnosis of colorectal carcinoma may be challenging, and this case emphasizes the need to consider intestinal endometriosis in females at a fertile age presenting with gastrointestinal symptoms and an intestinal mass causing complete large bowel obstruction.info:eu-repo/semantics/publishedVersio
New forms of land grabbing due to the bioeconomy. The case of Brazil
The present study discusses new forms of land grabbing related to biofuel production in the light of bioeconomic development. With a specific focus on Brazil, this article debates whether biofuel production is associated with (i) an expansion of agricultural land use-regarded as a process of unsustainable crop intensification or (ii) an increase in crop yield, driven by technical innovation with stable land use-intended as a form of sustainable intensification. We conclude that, in the case of Brazil, the current bioeconomy cannot be assumed to be environmentally sustainable. Starting from Brazil's experience, the (apparent and latent) relationship between bioeconomy and land grabbing requires a refined investigation in both wealthier and emerging economies, with the aim of proposing effective strategies to achieve truly sustainable development in the primary sector
Failure regime in (1+1) dimensions in fibrous materials
In this paper, we introduce a model for fracture in fibrous materials that
takes into account the rupture height of the fibers, in contrast with previous
models. Thus, we obtain the profile of the fracture and calculate its
roughness, defined as the variance around the mean height. We investigate the
relationship between the fracture roughness and the fracture toughness.Comment: 4 pages, 4 figures.eps, Revte
