1. COMPARAÇÃO DE MÉTODOS PARA DETERMINAÇÃO DE SUBSTÂNCIAS HÚMICAS EM FERTILIZANTES LÍQUIDOS COMERCIAIS
The beneficial effects of humic substances (HS) on crop development have been evidenced in the last decade, leading to the commercialization of HS products with fertilizing properties. Currently, three methods are frequently used for HS determination: method described in the manual of the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA); method

3. ENRAIZAMIENTO DE VITROPLANTAS DE MEMBRILLO (Cydonia oblonga) POR MEDIO DE INMERSIÓN TEMPORAL AUTOMATIZADA Y SU ACLIMATACIÓN
ABSTRACT Quince (Cydonia oblonga) is a non-traditional fruit tree found in Costa Rica that has therapeutic and nutritional properties; however its slow growth and root formation prevents the production of a homogeneous population when using conventional farming techniques. Hence, the aim of this research project was to generate uniform plant material in a re

4. Effects of pentoxifylline treatment before freezing on motility, viability and acrosome status of poor quality human spermatozoa cryopreserved by the liquid nitrogen vapor method
The objective of the present study was to investigate the effects of the direct addition of pentoxifylline (PF) to the ejaculates of men with poor sperm quality before freezing on post-thaw sperm motility, viability, acrosome integrity, and agonist-induced acrosome reaction. Semen specimens from 16 infertile men with impaired sperm count and motility (oligoa

5. Effect of external cryoprotectants on the in vitro viability of frozen spermatozoa of SWISS-ALBINA and BALB/c mice (Mus musculus). / Efeito de crioprotetores externos sobre a viabilidade in vitro de espermatozóides congelados de camundongos (Musmusculus) das linhagens SWISSALBINA e BALB/c.
The genetic progress obtained with trangenesis required the development and consolidation of reproductive techniques such as in vitro embryo production and gamete cryopreservation. With the diversity of new models and genetic lines, it became critical to optimize the use of experimental techniques of cryopreservation of semen in different animal species. The

6. Projeto, construção e avaliação de uma servovalvula dosadora para sistemas de aplicação de fertilizantes liquidos a taxas variaveis
This work had as aim to project, to build and to evaluate a flow control servo-valve for liquid fertilizer application in variable rates, as well as to conceive a system with capacity for formulation and dosage in which the valve can operate. It was conceived a system capable to work with three concentrate formulations simultaneously, using three independent
