The value of the Ecological Station of JataÝ's ecosystem services and natural capital

The capacity of a given natural ecosystem to provide certain goods and services that satisfy human needs depends on its environmental characteristics (natural processes and components). It was described the availability of these goods and services (environmental functions) controlled and sustained by ecological processes operating in Ecological Station of JataÝ (Luiz Antônio, SP). The environmental functions identified were grouped in four main categories. To make environmental values an integrated factor in planning and decision making it was assessed their socio-economic importance in qualitative terms and, if possible their monetary value. The combined potential annual return from identified functions of Ecological Station of Jataí is at least US$ 708.83/ha/year. In comparison to calculations made for other natural ecosystems this is a rather moderate estimate. The Ecological Station of JataÝ is poorly protected and managed, it too is still threatened by human activity (agriculture) and many development plans. Although present day market economics do not recognize the monetary value of most environmental functions, such calculations do provide a revealing insight into the great socio-economic importance of Ecological Station of Jataí. More awareness of these values may provide an important incentive for their preservation and sustainable use

Emprego do bisturi eletrico na seccao das tunicas e na hemostasia dos vasos da submucosa nas anastomoses do tubo digestivo. / Use of eletric cautery in section of the tunicae and in the hemostasis of submucous veins in the anastomosis of digestive tube

Os autores analisam os resultados obtidos com o emprego do bisturi eletrico, tanto na seccao das tunicas do tubo digestivo a serem anastomosadas ou suturadas, quanto na hemostasia dos vasos da submucosa, no preparo da boca anastomotica, em 183 doentes submetidos a cirurgia do tubo digestivo, com justaposicao das bordas. O metodo oferece a seguranca necessaria a sua utilizacao rotineira, sendo a principal vantagem a simplicidade, reduzido sensivelmente o tempo operatorio e tornado a sutura em plano unico mais simples e portanto mais acessivel a todos os cirurgioes que a praticam
