Plancto e hidrobiologia sanitária de tanques tropicais com dáfnias e rotíferos

The engineers of the modern University City are constructing a graceful bridge, named PONTE OSWALDO CRUZ, that crosses a portion of the Guanabara Bay (Fig. 1). The work at west pillar stopped for 3 years (The concret structure in Est. 1). As it will be seen from n.º 1 — 5 of the fig. 1, Est. I, the base of the structure will have five underground boxes of reinforcement, but, to-day they are just like as five uncovered water ponds, until at present: May 1963. (Est. I — fig. 3, n.º 3 — pond n.º 3; A. — old level of the water; B.— actual level of the water; c.— green water; E.— mass of bloom of blue algae Microcystis aeruginosa). Soon after SW portion, as 5 cells in series, of the pillar abutments, and also the NE portion nearly opposite in the Tibau Mount will be filled up with earth, a new way will link Rio City and the University City. We see to day Est. I, fig. 1 — the grasses on the half arenous beach of the Tibau Point. These natural Cyperaceae and Gramineae will be desappear because of so a new road, now under construction, when completed will be 33 feet above the mean sea level, as high as the pillar, covering exactly as that place. Although rainfall was the chief source of water for these ponds, the first water (before meterorological precipitations of whatever first rain it might fall) was a common tap water mixed with Portland Cement, which exuded gradually through the pores of the concret during its hardenning process. Some data of its first cement water composition are on the chemical table, and in Tab. n.º 4 and "Resultado n.º 1". The rain — receiving surface of each pond were about 15 by 16 feet, that is, 240 square feet; when they were full of water, their depth was of 2 feet 3", having each pond about 4,000 gallons. Climatic conditions are obviously similar of those of the Rio de Janeiro City: records of temperature, of precipitation and evaporation are seen on the graphics, figs. 2, 3, 4. Our conceptions of 4 phases is merely to satisfy an easy explanation thus the first phase that of exudation of concrete. We consider the 2nd. phase formation of bacterian and cyanophycean thin pellicel. 3rd. phase - dilution by rains, and fertilisation by birds; the 4th phase - plankton flora and fauna established. The biological material arrived with the air, the rains, and also with contaminations by dusts; with big portion of sand, of earth, and leaves of trees resulted of the SW wind actions in the storming days (See - Est. I, fig. 3, G. - the mangrove trees of the Pinheiro Island). Many birds set down and rest upon the pillar structure, its faeces which are good fertilizers fall into the ponds. Some birds were commonly pigeons, black ravens, swallows, sparrows and other sea mews, moor hens, and a few sea birds of comparatively rare occurence. We get only some examples of tropical dust contaminated helioplankton, of which incipient observations were been done sparcely. See the systematic list of the species of plankters. Phytoplankters - Cyanophyta algae as a basic part for food of zooplankters, represented chiefly by rotiferse, water-fleas Moinodaphnia and other Crustacea: Ostracoda Copepoda and Insecta: Chironomidae and Culicidae larvae. The polysaprobic of septic irruptions have not been done only by heating in summer, and, a good reason of that, for example: when the fifth pond was in polysaprobic phase as the same time an alike septic phase do not happened into the 3rd. pond, therefore, both were in the same conditions of temperature, but with unlike contaminations. Among the most important aquatic organisms used as indicatiors of pollution - and microorganisms of real importance in the field of sanitary science, by authorities of renown, for instance: PALMER, PRESCOTT, INGRAM, LIEBMANN, we choose following microalgae: a) The cosmopolite algae Scenedesmus quadricuada, a common indicator in mesosaprobio waters, which lives between pH 7,0 and it is assimilative of NO[3 subscripted] and NH[4 subscripted]. b) Species of the genus Chlamydomonas; it is even possible that all the species of theses genus inhabit strong-mesosaprobic to polysaprobic waters when in massive blooms. c) Several species of Euglenaceae in fast growing number, at the same time of the protozoa Amoebidae, Vorticellidae and simultaneous with deposition of the decaying cells of the blue algae Anacystis cyanea (= Microcystis) when the consumed oxygen by organic matter resulted in 40 mg. L. But, we found, among various Euglenacea the cosmopolite species (Euglena viridis, a well known polysaprobic indicatior of which presence occur in septic zone. d) Analcystis cyanea (= M. aeruginosa) as we observed was in blooms increasing to the order of billions of cells per litter, its maximum in the summer. Temperatures 73ºF to 82ºF but even 90ºF, the pH higher than 8. When these blue algae was joined to the rotifer Brachionus calyflorus the waters gets a milky appearance, but greenished one. In fact, that cosmopolite algae is used as a mesosaprobic indicator. Into the water of the ponds its predominance finished when the septic polysaprobic conditions began. e) Ankistrodesmus falcatus was present in the 5th pond from 26the. April untill the 26th July, and when N.NH[4 subscripted] gets 1.28 mg. L. and when chlorinity stayed from 0.034 to 0.061 mg. L. It never was found at N.NH[4 subscripted] higher than 1 mg. L. The green algae A. falcatus, an indicatior of pollution, lives in moderate mesosaprobic waters. f) As everyone knows, the rotifer eggs may be widely dispersed by wind. The rotifer Asplanchna brightwelli in our observation seemed like a green colored bag, overcharged by green cells and detritus, specially into its spacious stomach, which ends blindly (the intestine, cloaca, being absent). The stock of Asplanchna in the ponds, during the construction of the bridge "PONTE OSWALDO CRUZ" inhabits alkaline waters, pH 8,0 a 8,3, and when we observed we noted its dissolved oxygen from 3.5 to 4 mg. L. In these ponds Asplanchna lived in 0,2 P.PO[4 subscripted]. (Remember the hydobiological observations foreign to braslian waters refer only from 0.06 to 0,010 mg. L. P.PO[4 subscripted]; and they refer resistance to 0.8 N.NH[4 subscripted]). By our data, that rotiger resist commonly to 1.2 until 1.8 mg. L.N.NH[4 subscripted]; here in our ponds and, when NO[2 subscripted] appears Asplanchna desappears. It may be that Asplanchna were devoured by nitrite resistant animals of by Culicidae or other mosquitoes devoured by Due to these facts the number and the distribution of Asplanchna varies considerabley; see - plates of plankton successions. g) Brachionus one of the commonest members of class Rotatoria was frquently found in abundance into the ponds, and we notice an important biological change produce by the rotifer Brachonus colyciflorus: the occurence of its Brachionus clayciflorus forms pallas, is rare in Brazil, as we know about this. h) When we found the water flea MOinodaphnia we do not record simultanous presence of the blue algae Agmenellun (= Merismopedia).

The immunomodulatory effects of behavior

Evidence is presented indicating that behavioral conditioning techniques can be used to suppress and enhance antibody- and cell-mediated immune responses. Application of conditioning techniques in the pharmacotherapy of autoimmune disease in New Zeland mice resulted in a delay in the onset of lupus using a cumulative dose of immunosuppressive drug that was not, by itself, sufficient to alter the course of the autoimmune disease. Convesely, behavioral studies in lupus-proneMrl lpr (lpr and Mrl +/+ mice suggest further that immune status can influence behavior and that such behavior may serve to correct and immunologic dysregulation. Theses data are interpreted to indicate behavior can serve an immunomodulatory function.

Variation d'expression des récepteurs hormonaux et d'HER-2 dans l'évolution du cancer du sein : quelles implications en pratique clinique [Hormone receptors and HER-2 changes during breast cancer progression: clinical implications].

Breast cancer remains a major public health problem. Even if there is an increase in this cancer curability, metastatic breast cancer remains a lethal disease in the vast majority of cases. Therapeutic advances in the chemotherapeutic and targeted therapies fields induced an increase in survival, however the proportion of long survivors remains low. Phenotypic instability, an early process initiated during tumour progression, and continued on the metastatic stage of the disease, can be one of the putative hypotheses explaining these results. An increasing amount of scientific data are pledging for a reanalysis of the phenotypic profile regarding hormone receptors and HER-2 status of metastatic lesions in order to identify drugable targets and allow individualisation of the treatment of these metastatic breast cancer patients. Phenotypic changes between the primary tumour and the paired metastatic lymph nodes are a challenging pitfall, raising the question of which site has to be assessed in the adjuvant treatment decision process. This article presents a comprehensive analysis of the frequency of theses phenotypic changes altogether with new modalities to evaluate this phenotypic status.

A Study of a Staff Alcohol Policy in a Large Public Health Organisation, Looking at the Policy Content, the Policy Development and the Implementation Process, and the Policy Impact

There are different approaches to dealing with alcohol related problems in the workplace. A literature review indicates that two of the models that underpin programmes to deal with alcohol related problems in the workplace are the disease model and the health promotion model. The disease model considers alcoholism as an illness and uses curative techniques to restore the individual to sobriety. The health promotion model looks at the determinants of health and promotes changes in the environment and structures, which would support healthy behaviour in relation to alcohol. Employee Assistance Programmes (EAPs) may have elements of both theses models. Dealing with alcohol problems at work involves a captive audience and the workplace as a setting can be used to influence healthier lifestyles. A workplace alcohol policy is a mechanism through which alcohol related issues might be dealt with, and the necessary resources and commitment of managers and staff channelled to this end. The policy aims should be clear and unambiguous, and specific plans put in place for implementing all aspects of the policy. In the case of the alcohol policy in the organisation under study, the policy was underpinned by a health promotion ethos and the policy document reflects broad aims and objectives to support this. The steering group that oversaw the development of the policy had particular needs of their own which they brought to the development process. The common theme in their needs was how to identify and support employees with alcohol related problems within an equitable staff welfare system. The role of the supervisor was recognised as crucial and training was provided to introduce the skills needed for an early intervention and constructive confrontation with employees who had alcohol related problems. Opportunities provided by this policy initiative to deal with broader issues around alcohol and to consider the determinants of health in relation to alcohol were not fully utilised. The policy formalised the procedures for dealing with people who have alcohol related problems in an equitable and supportive manner. The wider aspect of the health promotion approach does not appear to have been a priority in the development and implementation of the policy.This resource was contributed by The National Documentation Centre on Drug Use.

La gestión de los recursos digitales en una biblioteca virtual : la Biblioteca virtual de la UOC

Les Biblioteques i Centres de Documentació han exercit sempre un paper molt important en el desenvolupament de l'aprenentatge, de la docència i de la investigació, però el canvi experimentat en aquests últims anys en l'àmbit docent, ha potenciat la funció d'aquest tipus de centres que han incorporat paulatinament una gran quantitat i varietat de recursos multimèdia d'informació, dissenyant i incorporant al mateix temps sistemes i programes de gestió que permetin un accés fàcil, amigable i eficient a aquests recursos. En el present article s'exposa l'experiència d'una biblioteca / centre de documentació virtual, per donar solució a una realitat que a poc a poc estan assumint la majoria de biblioteques universitàries espanyoles.

La dinàmica de les práctiques científiques des del punt de vista de l'experiencialisme

La tesi doctoral titulada "La Dinàmica de les Pràctiques Científiques des d'un punt de vista experiencialista" té com a objectiu oferir una alternativa a les tesis de Kuhn defensades a l'"Estructura de les Revolucions Científiques". En aquest sentit, s'utilitzaran diferents experiments i models teòrics actuals en l'àmbit de les ciències cognitives per tal de superar la teoria estructuralista de la cognició, quee Kuhn proposa com la base de la seva filosofia de la ciència. Contràriament a aquesta teoria, l'experiencialisme se situa lluny de les tesis estructuralistes, en la mesura en què assumeix que la cognició humana emergeix des de la dinàmica interactiva dels agents cognitius humans entre ells en un entorn material, en tant que agents corporals. A partir d'aquesta interacció dinàmica, l'ésser humà genera un horitzó de sentit. Ja que la interacció entre els éssers humans en un entorn cultural i material és complex, dinàmic i canviant, la generació de sentit emergent no és com una estructura semàntica, coherent i sistemàtica, sinó que ha de ser considerada com un conjunt asistemàtic de perspectives exploratòries que se succeeixen en el temps, en funció dels diferents contextos i propòsits que un agent corporal porta a terme al llarg de la seva interacció dinàmica i temporal amb l'entorn. Com a resultat de tot això, els èssers humans apliquen diferents criteris interactius que donen lloc a diferents perspectives per categoritzar o estructurar el món material i cultural. Aquest punt de vista és completament diferent del kuhnià, donat que el segon argumenta que cada èsser humà té la seva pròpia Gestalt o estructura semàntica que projecta "a priori" sobre la realitat. Aquesta diferència serà molt important no només des d'un punt de vista teòric, sinó també des d'un punt de vista pràctic. Per exemple, s'argumentarà que en l'àmbit de la didàctica de les ciències empíriques, es poden produir canvis beneficiosos significatius si s'utilitzen tesis extretes del model experiencialista de la cognició humana, i es deixen de banda el cognitivisme i el teoreticisme, que són actualment les bases teòriques de la manera en qué funciona l'educació científica. Finalment, conclourem afirmant que la visió experiencialista de la cognició implica assumir una forta relació entre l'ètica i la ciència, puix que els èssers humans són capaços d'utilitzar diferents criteris interactius per explorar la realitat i, per tant, sempre poden buscar millors estragègies per entendre's els uns amb els altres.
