Monitoring Plant Height and Spatial Distribution of Biometrics with a Low-Cost Proximal Platform.

Measuring canopy height is important for phenotyping as it has been identified as the most relevant parameter for the fast determination of plant mass and carbon stock, as well as crop responses and their spatial variability. In this work, we develop a low-cost tool for measuring plant height proximally based on an ultrasound sensor for flexible use in static or on-the-go mode. The tool was lab-tested and field-tested on crop systems of different geometry and spacings: in a static setting on faba bean ( L.

Ethel Parsons' biographical characteristics: leadership in American and Brazilian nursing.

Objective: to reconstruct Ethel Parsons' biographical aspects in the centenary of the technical cooperation mission for nursing development in Brazil.

Method: biographical research, carried out using the historical sources analysis method, which consists of reading and interpreting the collected documents.

Results: from a renowned family, Ethel Parsons was head of public health services and worked for the American Red Cross before being appointed to coordinate the Rockefeller Foundation mission in Brazil, where she inaugurated the Anglo-American model of nursing.

Toward a History of Health Care: Repositioning the Histories of Nursing and Medicine.

This positioning paper presents a new paradigm for the history of both nursing and medicine that will involve studying these actors and their practices in relation to each other rather than, as we have done, in isolation. This is not to say that both disciplines have had the same orientation and the same ambitions. Nursing, as I argue, has had a more constant focus and impact on its particular communities; medicine, by contrast, more successfully articulated a commitment to depersonalized knowledge and expertise that seemed to transcend individual and community experiences.
