Erosividade das chuvas e sua distribuição entre 1989 e 1998 no município de Lages (SC)

A erosão hídrica resulta da erosividade das chuvas e da erodibilidade dos solos. O conhecimento da erosividade, portanto, torna-se um guia valioso na recomendação de práticas de manejo e conservação do solo que visem à redução da erosão hídrica. O objetivo do trabalho foi identificar e quantificar o fator de erosividade das chuvas naturais de Lages (SC), bem como conhecer sua distribuição temporal. A pesquisa foi realizada em 2000, utilizando dados de chuvas e perdas de solo do período entre 1989 e 1998, no Centro de Ciências Agroveterinárias de Lages (SC), situado a 27º 49' de latitude Sul e 50º 20' de longitude Oeste, a 937 m de altitude média, na região do Planalto Sul Catarinense. Foram estudados diversos fatores de erosividade, utilizando os métodos de Wischmeier & Smith e de Wagner & Massambani, de 437 chuvas erosivas, num total de 966 chuvas, compreendendo um volume médio anual de 1.301 mm de chuvas erosivas, num total médio anual de 1.549 mm de chuvas. O EI30 é o fator de erosividade (fator R da Equação Universal de Perda de Solo - EUPS) recomendado para Lages, cujo valor médio anual é de 5.790 MJ mm ha-1 h-1; 63 % do qual ocorre na primavera-verão; 76 % no período de setembro a março e, no período crítico, outubro, janeiro e fevereiro, 41 % do referido fator. Considerando o número e o volume das chuvas, 45 e 84 %, respectivamente, são erosivas.

Vulgariser les sciences sans l'appui des savants. Jean Lanteires et le Journal de Lausanne (1786-1792)

Popularizing science without the support of scholars. Jean Lanteires and the Journal de Lausanne (1786-1792). - Founded in 1786 by Jean Lanteires, the Journal de Lausanne is a widespread, weekly journal with the express aim of disseminating scientific knowledge among the lower and middle classes. Its articles are easily comprehensible and cover a wide range of topics from literature to agriculture, from natural sciences to charity. Considerable space is given to reader's questions and comments. The journal can be situated somewhere between an almanac and a scientific journal. Lanteires' attempt to solicit contributions from scholars of medicine and natural sciences received a dismissive response. Of the few articles written by specialists, the majority deal with agriculture and charity. Lanteires' difficult relationship with the scholarly community is reflected in the journal's content. This makes the Journal de Lausanne a privileged observatory for studying the social context of the vulgarization process in late-eighteenth-century Switzerland and Europe.

"Vinci Cosmetics" Fabricación y comercialización de productos cosméticos

Contexto: La idea principal es la creación de una empresa para la fabricación y comercialización de productos cosméticos de alta gama. A pesar del contexto de crisis económica en el que estamos envueltos estos últimos años y del que no parece que acabamos de salir, el sector de la cosmética está resistiendo la situación de forma envidiable. De la crisis, como dicen los economistas, “se saldrá y se volverá, todo es cíclico” y viendo la fortaleza que éste sector está mostrando unido a la necesidad de que nuestra economía abandone sectores muy deteriorados y sin una previsión positiva de futuro, la cosmética se postula con un futuro prometedor dentro del contexto económico español y europeo. “Vinci Cosmetics” es el nombre inicialmente pensado para que la nueva compañía inicie su andadura. Nombre con tintes latinos de la lejana época del imperio romano como homenaje a la rica herencia histórica de la ciudad del autor del proyecto - Tarragona. La cultura por cuidarse y sentirse bien, muy arraigada en la mentalidad latina y mediterránea, es un factor cultural clave para el desarrollo y futura evolución de esta industria. El slogan de la empresa, “Dieta Mediterránea para tu piel”, clarifica en buena medida la idea a desarrollar y los objetivos pretendidos por la estrategia empresarial. Objetivos: El objetivo esencial del TFC es elaborar un estudio detallado para la creación de una empresa de fabricación y comercialización de productos cosméticos de alta gama que abarque el management y la gestión por procesos de la empresa, la función de marketing, el tipo de operaciones y procesos a realizar, la gestión del factor humano y el presupuesto necesario para cubrir este ambicioso proyecto. En detalle, un completo plan de empresa que marque las directrices de la organización industrial que se pretende crear compuesto a su vez por cinco planes: plan de gerencia, plan de marketing, plan de operaciones, plan de recursos humanos y plan económico – financiero. Procedimientos: El proyecto tiene un alto componente de estudio de mercados y de marketing pero pretende también abarcar el management, los procesos de operación, el factor humano y el aspecto económico y financiero de las inversiones y presupuesto necesario. El estudio inicial centrará su esfuerzo en un análisis del mercado de la península ibérica, y, en función del avance y del progreso esperado por la empresa, la compañía podría extender su campo de acción a Europa aunque no antes de un medio plazo. “Vinci Cosmetics” ha adoptado referenciales de sistemas de gestión integrados en toda la organización. Así tenemos principalmente, por un lado, la norma internacional ISO 9001:2008 y, por otro, el Modelo EFQM de Excelencia en la gestión; ambos plasmados a partir de un enfoque basado en procesos que nos garantiza el control continuo y la gestión excelente. Conclusiones: Tras evaluar la situación actual del mercado de la cosmética, las previsiones futuras de éste y las necesidades que una organización industrial necesita, se puede crear - con plenas garantías de éxito como organización empresarial y desde el punto de vista económico - una empresa de cosméticos de alta gama para cubrir las necesidades de una parte de mercado que lo requiere.

Analysis by confocal microscopy of the behavior of heat shock protein 70 within the nucleus and of a nuclear matrix polypeptide during prolonged heat shock response in HeLa cells.

By means of confocal laser scanning microscopy and indirect fluorescence experiments we have examined the behavior of heat-shock protein 70 (HSP70) within the nucleus as well as of a nuclear matrix protein (M(r) = 125 kDa) during a prolonged heat-shock response (up to 24 h at 42 degrees C) in HeLa cells. In control cells HSP70 was mainly located in the cytoplasm. The protein translocated within the nucleus upon cell exposure to hyperthermia. The fluorescent pattern revealed by monoclonal antibody to HSP70 exhibited several changes during the 24-h-long incubation. The nuclear matrix protein showed changes in its location that were evident as early as 1 h after initiation of heat shock. After 7 h of treatment, the protein regained its original distribution. However, in the late stages of the hyperthermic treatment (17-24 h) the fluorescent pattern due to 125-kDa protein changed again and its original distribution was never observed again. These results show that HSP70 changes its localization within the nucleus conceivably because it is involved in solubilizing aggregated polypeptides present in different nuclear regions. Our data also strengthen the contention that proteins of the insoluble nucleoskeleton are involved in nuclear structure changes that occur during heat-shock response.

Propiedades psicométricas y estructura factorial de la Escala de Identidad Étnica Multigrupo en español (MEIM)

En este trabajo investigó la consistencia interna y la estructura factorial, comparando tres modelos de medición, de una versión en español de 12 ítems de la Escala de Identidad Étnica Multigrupo de Phinney, en una muestra de 631 estudiantes mexicanos (301 indígenas y 330 mestizos) entre 17 y 40 años de edad. Los resultados apoyan la consistencia interna de la medida y apuntan a una estructura de dos factores de la identidad étnica: la afirmación o identificación étnica y la exploración étnica. Así mismo, se encontraron diferencias estadísticamente significativas en los grupos estudiados, siendo los indígenas quienes puntúan más alto en identidad étnica y sus componentes. Sugerimos que se necesitan más investigaciones para evaluar la identidad étnica y validar la medida y los factores de la identidad étnica a través de diversos grupos étnicos con otras muestras de adolescentes y adultos de habla hispana

Anti-idiotypic monoclonal antibody AB3, reacting with the primary antigen (CEA), can localize in human colon-carcinoma xenografts as efficiently as AB1.

BALB/c mice were immunized with anti-idiotypic monoclonal (MAb) antibody (anti-Id or Ab2) directed against an AB1 MAb anti-carcinoembryonic (CEA) in order to obtain AB3 MAbs (anti-anti-Id). AB3 MAbs were shown to recognise the primary antigen (CEA) and one of them was tested extensively in vitro and in vivo. This AB3 MAb was shown to bind specifically to CEA on frozen sections of a human colon carcinoma by immunoperoxidase. Scatchard plot analyses showed that the affinity of this AB3 was of the same order of magnitude as the AB1. In vivo experiments, in nude mice bearing CEA-producing human colon-carcinoma xenografts showed that up to 30% of the intravenously injected dose of 125I-labelled AB3 were localized per gram of tumour tissue. Furthermore, calculation of the ratios of AB3 concentration in the tumour over those in normal organs such as lung, liver, kidney, spleen and bone gave relatively high values similar to results obtained with AB1. All together our results show that AB3 can localize as efficiently and specifically in the tumour as AB1, despite the fact that the mice from which it was derived were immunized with a mouse MAb (AB2) and had never been exposed to CEA.

De la dyschronie chez les enfants instables : hyptohèse d'une difficulté d'instauration d'un temps transitionnel.

Résumé - De la dyschronie chez les enfants instables, hypothèse d'une difficulté d'instauration d'un temps transitionnel. Du syndrome d'asynergie motrice et mentale de Wallon (1925) au déficit d'inhibition du comportement de Barkley (1997), l'agitation de l'enfant a souvent été liée à une difficulté à penser, organiser et partager les représentations inhérentes à la temporalité. La dyschronie, telle que formulée par Gibello (1976), constitue une théorie heuristique pour penser ce défaut de symbolisation du temps. Pour mieux comprendre ces phénomènes, plusieurs épreuves projectives (Rorschach, TAT, dessins) ont été proposées à un jeune garçon instable dyschronique. Les analyses mettent en évidence une discontinuité des capacités représentatives. Si une différence entre un protocole Rorschach qui s'est révélé restreint et un TAT abondant en constitue le premier signe, des indices spécifiques montrent une difficulté d'instauration d'une aire de jeu imaginaire stable ou plus précisément un manque de continuité dans les phénomènes transitionnels (Winnicott, 1975). Peut-on dès lors envisager un lien entre la difficulté de représentation des transformations (Gibello, 2004) et ce déficit d'instauration, non plus seulement d'un espace, mais aussi d'un temps où se représentent les transitions ?

Cataractogenesis after total body irradiation.

PURPOSE: To evaluate the prognostic factors and the ophthalmologic follow-up on cataract formation following total body irradiation (TBI) prior to bone marrow transplantation (BMT). METHODS AND MATERIALS: Between 1980 and 1992, 494 patients were referred to our department for TBI prior to BMT. The mean age was 32 +/- 11 (median: 32, range: 2-63) years and the male to female ratio was 1.6 (304:190). The majority of patients were treated for acute leukemia (lymphoblastic, n = 177, 36%; or nonlymphoblastic , n = 139, 28%); 80 (16%) for chronic myeloid leukemia, 60 (12%) for non-Hodgkin's lymphoma, 23 (5%) for multiple myeloma, and 15 (3%) for other malignancies. Two hundred and fifty-four (51%) patients were grafted in the first complete remission (CR), 118 (24%) in second CR. Allogenic BMT was performed in 210 (43%) patients, and autologous BMT in 284 (57%). Methotrexate combined to steroids (n = 47, 22%) or to cyclosporine (n = 163, 78%) was administered for graft-versus-host disease (GvHD) prophylaxis. In 188 patients (38%), heparin was used in the prevention of veno-occlusive disease (VOD) of the liver. Furthermore, steroid administration was registered in 223 (45%). The conditioning chemotherapy consisted of cyclophosphamide (Cy) alone in 332 (67%) patients. Total-body irradiation was administered either in single dose (STBI; 10 Gy in 1 day, n = 291) or in six fractions (FTBI; 12 Gy over 3 consecutive days, n = 203) before BMT. The mean instantaneous dose rate was 0.0574 +/- 0.0289 Gy/min (0.024-0.1783). It was < 0.048 Gy/min in 157 patients (LOW group), > or = 0.048 Gy/min and <0.09 Gy/min in 301 patients (MEDIUM group), and > or = 0.09 Gy/min in 36 patients (HIGH group). RESULTS: When considering all patients, 42 (8.5%) patients developed cataracts after 13 to 72 months (median: 42 months) with a 5-year estimated cataract incidence (ECI) of 23%. Thirty-three (11.3%) out of 291 patients in the STBI group, and 9 (4.4%) out of 203 patients in the FTBI group developed cataracts with 5-year estimated incidences of 34 and 11%, respectively (p = 0.0004). Seven (19.4%) out of 36 patients in the HIGH group, 33 (10.9%) out of 301 in the MEDIUM group, and 2 (1.2%) out of 157 in the LOW group developed cataracts with respective 5-year cataract incidences of 54%, 30%, and 3.5% (HIGH vs. MEDIUM, p = 0.07; MEDIUM vs. LOW, p = 0.0001; HIGH vs. LOW, p < 0.0001). On the other hand, patients who received heparin as prophylactic treatment against VOD of the liver had less cataracts than those who did not receive (5-year ECI of 16% vs. 28%, respectively; p = 0.01). There was no statistically significant difference in terms of 5-year ECI according to age, sex, administration of steroids, GvHD prophylaxis, type of BMT, or previous cranial radiotherapy in children. Multivariate analysis revealed that the instantaneous dose rate (p = 0.001), and the administration of heparin against VOD (p = 0.05) were the two independent factors influencing the cataract incidence, while age, fractionation, and use of steroids were not. Among the 42 patients who developed cataracts, 38 had bilateral extracapsular cataract extraction and intraocular lens implantation, and only 4 (10%) developed secondary cataracts in a median follow-up period of 39 months. CONCLUSION: Among the abovementioned TBI parameters, high instantaneous dose rate seems to be the main risk factor of cataract formation, and the administration of heparin appears to have a protective role in cataractogenesis. On the other hand, ionizing radiation seems to have a protective effect on posterior capsule opacification following extracapsular cataract extraction and intraocular lens implantation.
