Utilización de columnas verticales de filtración de manta y arena como pre-tratamiento de un sistema de filtración lenta

Slow sand filtration is an efficient water treatment technique used for treating surface water with relatively low levels of contamination. Despite the slow sand filtration at pathogen, algae and cyanobacteria removal efficiency, it has some restrictions in relation to the required area for slow filters, and the cleaning activities for the filters and the stone pre-filters when used in the treatment. This research evaluated during 120 days the use of non woven & sand pre-filtration columns as part of a slow filtration process for the apparent color, turbidity, algae, cyanobacteria, phytoflagellates and diatomaceous. The columns shown an efficient removal of the monitored parameters and demonstrated as a vantage their faster and easier cleaning process and less awkward than the required to the stone pre-filters. The turbidity removal efficiency increased progressively during the experiment, especially after the first 35 days of the start; the apparent color removal by the pre-filtration columns was of 85%, and working together with the polishing of activated carbon columns was up to 95; the diatomaceous, phytoflagellates, algae and cyanobacteria removal by the columns achieve a weekly average of 95%, its recommended to use filtration rates lower to 1,5m(3)/m(2)/d.

Tratamiento de la hiperhidrosis palmar primaria por acupuntura: a propósito de un caso

Primary hyperhidrosis is an excessive sweating disorder that occurs in axillae, palms, soles, and craniofacial region. According to Traditional Chinese Medicine (TCM) it is a water metabolism disorder. This study presents a case report treated with TCM, showing more satisfactory results than those by conventional treatments.

Épocas de la aplicación de desecantes en el cultivo de la soja: tenor de agua y productividad

Los herbicidas glifosato y paraquat son utilizados por los productores de soja con el objetivo de desecar las plantas, anticipar y uniformizar la cosecha. Sin embargo, el uso indiscriminado de herbicidas puede causar problemas eventualmente en las características agronómicas y fisiológicas del cultivo. El presente trabajo tuvo por objetivo evaluar la utilización de los herbicidas glifosato y paraquat como desecantes para el cultivo de la soja. El experimento fue llevado a cabo en el año agrícola 2005/06, en un delineamiento experimental de bloques al azar, con cuatro repeticiones. Los tratamientos fueron dispuestos en dos esquemas factoriales, 3x3x5x2 y 3x2x5x2: dos desecantes (glifosato y paraquat) y un testigo (sin desecación), aplicación de los desecantes en tres y dos estadios fenológicos de las plantas (R6, R7 y R8) y (R7 y R8), para las variedades MSOY 6101 de ciclo superprecoz, y MG/BR 46 (Conquista) de ciclo precoz, respectivamente, cinco épocas de muestreo (2; 4; 6; 8 y 10 días después de la aplicación) y evaluación en dos posiciones en la planta (ápice y base). Fue evaluada la producción de semillas, masa y tenor de agua de 100 semillas. Los desecantes evaluados fueron eficientes en la reducción del tenor de agua de las semillas, sin afectar la productividad y la masa de 100 semillas.

Plantas medicinais: indicação popular de uso no tratamento de hipertensão arterial sistêmica (HAS)

The aim of this study is to investigate the spontaneous use of medicinal plants by volunteer patients in the treatment of hypertension and to determine the most used plants in this situation. Data were collected through a questionnaire and a semi-structured guided interview applied to patients from a health center in the Midwest region of the state of Sao Paulo, Brazil. Quantitative analysis identified a high number of hypertensive patients spontaneously using herbal treatment. The referred plants were identified by the Herbarium Botu and researched in the literature as to their therapeutic actions. The biggest mistake was observed in the misuse of the Bilberry for the treatment of hypertension, which reveals that health professionals and the community in general should be more careful. As a result we have published an informative booklet, with emphasis on hypertension concepts and on the use of medicinal plants as an alternative therapy method for this disease in order to provide scientific knowledge and scientific research evidence to this practice.
