Highly porous Ti matrix composites can be a solution for some of the major clinical concerns for the load bearing implants such as low tribocorrosion resistance, stress shielding, and lack of biological anchorage. In order to respond to these needs, highly porous Ti-TiB-TiNx in-situ composites were synthesized by pressureless sintering using BN as reactant and urea as space holder. Corrosion behaviour was investigated at body temperature, in phosphate buffer saline solution (PBS), by measuring open circuit potential (OCP) and cyclic polarization.

Polar bears are uniquely adapted to an Arctic existence. Since their relatively recent divergence from their closest living relative, brown bears, less than 500,000 years ago, the species has evolved an array of novel traits suited to its Arctic lifestyle.

Joint sentiment-topic (JST) model was previously proposed to detect sentiment and topic simultaneously from text. The only supervision required by JST model learning is domain-independent polarity word priors. In this paper, we modify the JST model by incorporating word polarity priors through modifying the topic-word Dirichlet priors.

F-ATP synthase synthesizes ATP at the expense of ion motive forcebyarotarycouplingmechanism. Acentral shaft, subunitc, functionally connects the ion-driven rotary motor, FO, with the rotary chemical reactor, F1.Using polarized spectrophotometry we have demonstrated previ-ously the functional rotation of the C-terminala-helical portion ofcin the supposed ‘hydrophobic bearing’ formed by the (ab)3hexagon. In apparent contradiction with these spectroscopic results, an engineered disulfide bridge between thea-helixofcand subunitadidnot impair enzyme activity....

A robust body of literature details reproductive effects in fish, amphibians, and reptiles related to exposure to endocrine disruptors. Evidence of these effects has also been seen in wild mammals such as polar bears and seals. Environmental exposure assessments and wildlife, laboratory and epidemiologic studies show exposure to low-level environmental contaminants, such as pesticides and other chemicals, subtly undermines the ability to reproduce.

IT WAS EARLY in March, 1969, that I set out from my bleak camp on the desolate shore some fifty miles southeast of Herschel Island after polar bear. I had come into the Arctic the year before to enjoy the first real vacation that I had ever had. The definite close of the Great War, in April two years before, had left an exhausted world at peace-a condition that had never before existed and with which we did not know how to cope. I think that we all felt lost without war-I know that I did; but I managed to keep pretty busy with the changes that...

Do you want to learn how to draw a cartoon polar bear cub? Take to the ice and get your pencil at the ready to draw this cute polar bear! It's easy when you follow our four simple paw prints. Brrrrr! With more "ice" than Kanye West, the polar bear is the undisputed king of the Arctic Circle and this cute little cub is just finding his feet (or, should that be paws?) in the snow.

Toxicity Acute toxicity of vitamin A was first noted in Arctic explorers who ate polar bear liver and has also been seen after administration of 150 mg in adults or 100 mg in children. Acute toxicity is manifested by increased intracranial pressure, vertigo, diplopia, bulging fontanels in children, seizures, and exfoliative dermatitis; it may result in death. In children being treated for vitamin A deficiency according to the protocols outlined above, transient bulging of fontanels occurs in 2% of infants, and transient nausea, vomiting, and headache occur in 5% of preschoolers.

We use can to say that someone has the ability or opportunity to do something. The negative of can is cannot (contraction: can't). Can you swim? He can play the guitar. It's nice today. We can sit in the garden. I can't open this bottle. could for the italicized verbs if possible. 1. We had a good time yesterday. We went to the zoo. The children enjoyed themselves very much. They saw polar bears and elephants. (No substitution of 'could' is possible.) 2. When I lived in St. Louis, I went to the zoo whenever I wanted to, but now I live in a small town...
