5. Nuts and Cardiovascular Diseases: Focus on Brazil Nuts
Abstract Cardiovascular diseases (CVD) are the main cause of death globally and most CVD can be prevented by addressing their risk factors, such as an unhealthy diet. Many authors have studied the benefits of nut consumption on CVD. Nuts contain high amounts of vegetable protein, unsaturated fatty acids, dietary fibers, vitamins, minerals and many other bioa

7. Comparative Study About Mechanical Properties of Strutural Standard Concrete and Concrete with Addition of Vegetable Fibers
This paper explored the effect of adding organic fibers from either bamboo or sugarcane on the mechanical properties of concrete. Cylindrical and prismatic specimens were made containing 2% and 5% v/w (volume to weight) of vegetable fibers to concrete. Following 28 days of curing period, the samples were evaluated for compressive strength, tensile strength u

11. Stingless bees damage broccoli inflorescences when collecting fibers for nest building
The stingless bee Trigona spinipes (Fabricius, 1793) (Hymenoptera: Apidae) is an important pollinator for various crops, but constitutes an occasional pest of other plant species since it causes injury to leaves, stems, flowers and fruits while collecting nest materials. The aim of the present study was to determine the damage caused by T. spinipes to a broc

12. Desenvolvimento de um laminado compósito híbrido a base de fibras de vidro/licurí
This research work is based, in search of reinforcements vegetable alternative to polymer composites. The idealization of making a hybrid composite reinforced with vegetable fibers licuri with synthetic fibers is a pioneer in this area. Thus was conceived a hybrid composite laminate consisting of 05 (five) layers being 03 (three) webs of synthetic fibers of
