Sediment denitrification was monthly evaluated in two tropical coastal lagoons with different trophic states using the N-15 isotope pairing technique. Denitrification rates were very low in both environments, always < 5.0 mu mol N-2 m(-2) h(-1) and were not significantly different between them. Oxygen consumption varied from 426 to 4248 mu mol O-2 m(-2) h(-1) and was generally three times higher in the meso-eutrophic than the oligotrophic lagoon. The low denitrification activity was ascribed to both low water NO3- concentrations (< 2.0 mu M) and little nitrate supply from nitrification. There was no correlation of denitrification with nitrate or ammonium fluxes. Sediments in temperate environments with similar oxygen consumption rates usually presented a higher proportion of nitrification-denitrification rates. Sediment oxygen consumption was a good predictor of sediment denitrification in both studied lagoons., Funding Agencies|FAPERJ; CAPES; CNPq; Petrobras; Inter-American Institute for Global Change Research

Background Very little is known about the general appropriateness of prescribing for psychiatric patients. Aims To identify prevalence and types of potentially inappropriate prescribing (PIP) of psychotropic and somatic medications, to assess the severity of potential clinical consequences and to identify possible predictive factors of PIP in a sample of adult psychiatric in-patients. Methods A descriptive, cross-sectional design using medication reviews by clinical pharmacologists to identify PIP during a 3-month period. The setting was in-patient units in a psychiatric department of a Danish university hospital during a 3-month period (September 2013–November 2013). Patients medication lists (n = 207) were reviewed at the time of admission and all identified PIPs were assessed for potential consequences by clinical pharmacologists. Results There were 349 PIP identified in 1291 prescriptions. The proportion of patients found to have at least one PIP was 123/207 (59%) and the proportions of patients with at least one PIP assessed to be potentially serious or fatal was 69/207 (33%) and 24/207 (12%), respectively. Interactions between drugs 125/207 (36%) and too high doses of drugs 56/207 (16%) were the most frequent PIP. Predictive factors for PIP were polypharmacy (>5 prescriptions) and having one or more somatic diagnoses. Conclusion PIP is common in psychiatric patients and potentially fatal. Particularly polypharmacy (>5 prescriptions) and concomitant somatic illness were associated with the probability of PIP. Improving the quality of prescribing might benefit from an interprofessional approach and thus better training of physicians and nurses is needed in order to minimize PIP.

The Government Documents Department of the University of North Texas (UNT) Libraries brings to the Web the first ten volumes of Gammel's The Laws of Texas. Published over one hundred years ago (1822-1897), The Laws compile documents from the time of colonization through statehood, including congressional and legislative sessions, constitutions, selected journals of the constitutional conventions, and early colonization laws. The volumes have never been reprinted, despite their importance to researchers, so Web access will be welcomed by legal historians and historians of Texas. All of the pages are available in .pdf format. Users can browse The Laws by volume or perform a keyword search; happily the UNT Libraries search engine is configured to search the content of .pdf files.
