Materials and methods A prospective controlled study was done with 38 adolescent idiopathic scoliosis patients (6 male; 32 female, 13.5 +/3.5 years of age; Risser 0-3; Cobb Angle > 10°, Bunnel Angle > 5°) who were prescribed only exercises to avoid progression at the time of their first evaluation. All patients were enrolled consecutively. Patient were then divided into three groups: SEAS group...

Alpine glaciers have receded substantially over the last century in many regions of the world. Resulting changes in glacial runoff not only affect the hydrological cycle, but can also alter the physical (i.e., turbidity from glacial flour) and biogeochemical properties of downstream ecosystems. Here we compare nutrient concentrations, transparency gradients, algal biomass, and fossil diatom spe...

Curators of large aquaria where there is no significant primary production and water changes are impractical have been using biological denitrification to control high nitrate concentrations. The two denitrification systems described in this study operate in different ways: the Living Seas uses a batch system, while the New Jersey State Aquarium uses a flow-through system. The rate of denitrifi...

Wada, K. and K. Kawaguchi, Efficient fault-tolerant fixed routings on (k+ 1)connected digraphs, Discrete Applied Mathematics 37/38 (1992) 539-552. Consider a directed communication network G in which a limited number of directed link and/or node faults F might occur. A routing Q for the network (a fixed path for each ordered pair of nodes) must be chosen without knowing which components might b...

It is well known that for right-handed individuals, language is usually and mostly associated with the left hemisphere activity. The question of the potential bilateral representation of language, however, has been barely approached. The evidence regarding the bilateral representation of language taken from Wada test, PET, fMRI, tractography, and magneto-encephalography is examined. Departing f...

, Japan. E-mail : tsutsumi Received December , . Accepted February , . * @avis. ne. jp This paper discusses the procurement and utilization of obsidian by the microblade industries of the terminal Late Palaeolithic in the Chubu and Kanto districts of central Japan at the end of the last glaciation, cal BP. The core of the discussion is based on the source determinations for obsidian artifacts f...

We compared the stable carbon isotopic composition (d13C) of crustacean zooplankton with that of potential carbon sources in 15 lakes in northern Sweden with different dissolved organic carbon (DOC) concentrations (2–9 mg L21) to test the hypothesis that zooplankton depended more on allochthonous carbon in humic lakes than in clear-water lakes. Based on d13C signature, we found that the pool of...
