1978019658Washington: Smithsonian Institution 1978. Illustrated large octavo pp 231 with six folding charts in the rear pocket very slightly used internally paperback the covers very slightly used and age-toned the spine a little wrinkled. Polish collector of insects and plants in Peru. Woytkowski emigrated to Peru in 1929 where he collected more than a thousand insect species new to science and copious botanical specimens. He together with his new wife Helena was lured to Peru by a settlement company whose advertisements promised free passage and a homestead farm. In reality after landing in Callao he found himself with hundreds of other Europeans in a shanty immigrant camp waiting in vain for their free land. While most gave up and returned to their homes Woytkowski decided to stay in Peru with Helena and their four-year-old son settling in Yamaquezù near Oxapampa where he established himself as a naturalist collecting insects and plants to send to scientists in the United States and Europe. He was for seven years employed exclusively by the Swiss pharmaceutical firm CIBA looking for plants that could be used in medicines and also served on the staff of San Marcos University as a professor of French and La Molina College of Agriculture in Lima. Here he built up an extensive herbarium though he was best known for his entomological collections. He made numerous trips into Peru's mountainous areas and explored all the country's provinces both independently and on behalf of research institutions including the University of California and Missouri Botanical Garden. Although successful in his collecting career his family life was somewhat unhappy due to his constant need to move around which led his wife to leave him in the 1940s. After more than 30 years collecting in Peru he was dealt another blow when he found he could not draw a small pension from the Botanic Garden in Lima as he had never taken Peruvian citizenship. He thus returned to Poland in 1965 by now a strange land to him. Removed from his life's work and suffering in the colder climate he died in Krakow where he had been staying with his brother. Numerous insects are named in his honour including a genus of army ants. The plant genus Woytkowskia Woodson is also named for him. This memoir was published in Polish in 1974. First English edition.

A9781138198487Paperback / softback. New. With higher food quality in increasing demand by consumers there is continuous pressure on food engineers to meet market needs. One of the critical challenges is to use modern technology and knowledge to develop new processes for improving food quality. Given the global food marketplace there is also a greater need for a means of objectively classifying and differentiating foods. Physical properties determined by measurable physical parameters profoundly affect food quality and can be used for these determinations. Physical Properties of Foods: Novel Measurement Techniques and Applications presents a wide range of these practical low-cost techniques to characterize physical properties without destroying the food. The book presents principles and measurement techniques highlighting the latest methods and their ability to replace the traditional costly time-consuming ones. It also covers the application of the measurements to classify and differentiate various foods including fruits vegetables cereals and dairy and meat products. The text gathers up-to-date procedures for determining the most important physical parameters that characterize food quality many of which have not previously been sufficiently described in the literature and delivers them in one useful volume. It includes methods based on a variety of technologies such as electronics spectroscopy mechanics and acoustic response-which can be applied to a wide range of foods. With a focus on practical application of novel techniques chapters specify method details the type of food to which it has been applied the accuracy its ability to replace traditional techniques as well as whether it can be installed on line. Written by internationally renowned engineers and scientists this reference offers crucial information in an easily accessible format for engineers researchers and those in the food industry-all who will benefit from the cutting-edge practices described for measuring parameters that affect food quality and food characterization. The text is also an excellent resource for students and university researchers. paperback
