In this paper, the issue of adhesion to biological substrates for biomedical applications is addressed. In particular, taking inspiration from intestinal parasites, micro-hooks for clamping on the gastrointestinal wall have been studied, in order to provide future endoscopic micro-systems with the capability of attaching safely to the mucosa surface. A novel fabrication technology and experimen...

A pied cormorant (Phalacrocroax varius) was found sleeping on rocks in a coastal region near Adelaide. Examination revealed entanglement by fishing line with superficial wounds to the left leg. The cormorant was also reported to have ingested a number of fishing hooks, however, the exact location of the hooks was not known. In addition, the bird was found to be underweight and shocked. X-ray ex...

Sauracanthorhynchus sphenomorphicola n. gen., n. sp. from the intestines of the skink Sphenomorphus granulatus (Scincidae) from Papua New Guinea is described and illustrated. Sauracanthorhynchus sphenomorphicola is characterized by a subterminal, spheroid proboscis supporting 25 hooks arranged in 10 alternating longitudinal rows of 2 and 3; apical hooks slightly shorter than medial and posterio...

This article analyzes the work of feminist theorist and cultural critic bell hooks, paying special attention to place individual collective experience in her intellectual project. In this project, production knowledge attends experiences author black communities which she grew up, turn are re-signified light theories developed by hooks other exponents feminism. For attending is also a powerful ...

An in vitro system for reconstituting flagellar filaments onto hooks of filamentless mutants of Salmonella typhimurium was used to investigate the role played in filament formation by the three hook-associated proteins (HAPs, products of the flaW, flaU, and flaV genes). These proteins--FlaW, FlaU, and FlaV--are believed to be assembled in this order at the distal end of the hook. When the recip...

BACKGROUND The purposes of the present study were morphometric characterization of rostellar hooks of Taenia multiceps and to investigate the association of hook length variation and the variability within two mitochondrial genes of sheep isolates of the parasite. METHODS Up to 4500 sheep brains were examined for the presence of C. cerebralis. Biometric characters based on the larval rostella...

BACKGROUND The biomechanical performance of the hooks and screws in spinal posterior instrumentation is not well-characterized. Screw-bone interface failure at the uppermost and lowermost vertebrae is not uncommon. Some have advocated for the use of supplement hooks to prevent screw loosening. However, studies describing methods for combined hook and screw systems that fully address the benefit...

This article commemorates the legacy of bell hooks by bringing core themes in her oeuvre to bear on several debates conceptualization and use qualitative research methods sociology. Despite uptake sociology as a launching point for critical inquiry with analytical political overtones, they have been fragmented threefold about their politics (whether humanize subjects), practice intervene field ...

We compiled an improved version of the G-VRP model of Erdogan and Miller-Hooks (2012) and used it to solve the set of small G-VRP benchmark instances with CPLEX. To be concise, we use the original notation from Erdogan and Miller-Hooks (2012) to describe our model:

We present new expressions for generating functions of irreducible characters of the symmetric group Sn. These generating functions are of the form ∑∗ λ χ λ μq λ where the sum is over partitions λ of restricted shapes such as hooks and double hooks. We use the λ-ring theory for symmetric functions to demonstrate our statements.
