SULPHATE IN ESTUARINE AND SEA WATER SAMPLES Sulphate is an abundant ion in sea water. However, its concentration decreases in estuarine water, due to the dilution by the entrance of freshwater or the reduction to sulphide. Because of this, the determination of sulphate in estuarine and sea waters is essential to studies to monitor the water quality of the environment. Although the gravimetric method is the most common one for the analysis of sulphate in sea water, it is very time…

of physical and chemical parameters of water quality of the Ribeirão Abóbora. Abstract Water is essential for sustaining life, directly influences the health and well being of humankind and to ensure economic self-sufficiency regions virtues and defects of these are nothing more than the re ¬ flexion of the human actions directly or indirectly ¬ TAS that occur on the watershed. In this paper we present a study of physical-chemical parameters of water samples from the spring…

performed, the first one with the stemmed water from the Baixo Acaraú irrigation district, and another with the stemmed water from a small reservoir located within the lot studied. It was used data to calculate the Christiansen uniformity coefficient (CUC), uniform distribution (CUD) and the statistical uniformity coefficient (CUE). The results of CUC were 91% for the system that used water from irrigated district and 93,2% for the system that used water from small reservoir. Both…

narra o romance de dois adolescentes que se conhecem (e se apaixonam) em um Grupo de Apoio para Crianças com Câncer: Hazel, uma jovem de dezesseis anos que sobrevive graças auma droga revolucionária que detém a metástase em seus pulmões, e Augustus Waters, de dezessete, ex-jogador de basquete que perdeu a perna para o osteosarcoma. Como Hazel, Gus é inteligente, tem ótimosenso de humor e gosta de brincar com os clichês do mundo do câncer - a principal arma dos dois para enfrentar a…

calculate calm water performance as well as speed loss in waves within one product. Both of these features were implemented in the shipX Plug-In “ship speed and Powering”. the Plug-In is based on the work behind the MaRINteK products emPower (calm water resistance and propulsion) and seaway (speed loss in a seaway). When the ship encounters waves, the total resistance increases and the propeller thrust decreases. as a result, the ship cannot sustain the same forward speed as in calm…

Saúde Pública Chlorine Use in Water Disinfection, Trihalomethane Formation, and Potential Risks to Public Health Sheila T. Meyer1 MEYER, S. T. Chlorine Use in Water Disinfection, Trihalomethane Formation, and Potential Risks to Public Health. Cad. Saúde Públ., Rio de Janeiro, 10 (1): 99-110, Jan/Mar, 1994. Before the development of the germ theory — relating microorganisms with disease transmission (1880) — people believed that diseases were transmitted by odours. Water and sewage…

machine makes a lot of noise. The tree machine does not make any noise. On the contrary, it filters noise. The tree machine does not need coal, oil, gas or electricity to work. Its fuel comes from water, sunlight, and carbon dioxide. When a tree dies, it helps new plants. The combination of water, insects, and microorganisms in the soil causes the decomposition fo the tree. When a tree dies, it gives nutrients to the soil for other trees to use as fuel. So, the tree does not…

produzido o Pink Floyd The Wall. Baseado no álbum da banda, o filme é feito em live-action/animação musical. Roger Waters, baixista e vocalista da banda, escreveu seu roteiro com poucos diálogos, sendo mais metafórico, com as musicas de fundo sendo interpretadas e com seqüências de animação. Bob Geldof, da banda punk The Boomtown Rats estreia como o roqueiro frustrado Pink, apesar de Waters ter sido cogitado para o papel de protagonista. Apenas duas das musicas do álbum foram cortadas…

Palavras-chaves: comportamento, bezerros, anaplasmose, RFID, consumo de água ABSTRACT The objective was to validate the radio frequency system Intergado® for individual monitoring behavior and consumption of water and food in young cattle housed in groups and with the help of these, evaluate the water intake and food behavior in group-housed calves healthy and affected naturally by tick fever. Both studies used 35 Holstein-Gyr crossbred heifers divided into three groups of 12,…
