DESCRIPTION OF ULTRASTRUCTURAL DAMAGES IN FROZEN-THAWED CANINE SPERMATOZOA DESCRIÇÃO DE DANOS ULTRAESTRUTURAIS EM ESPERMATOZOIDES CANINOS CONGELADOS-DESCONGELADOS

DESCRIPTION OF ULTRASTRUCTURAL DAMAGES IN FROZEN-THAWED CANINE SPERMATOZOA DESCRIÇÃO DE DANOS ULTRAESTRUTURAIS EM ESPERMATOZOIDES CANINOS CONGELADOS-DESCONGELADOS

In spite of the advances in transmission electronic microscopy (TEM), there are few studies presenting a systematic description of the canine spermatozoa and they are only focused on sperm cell heads.The goal of the present study was to describe ultrastructural appearance of canine fresh and frozen-thawed spermatozoa, focusing on damages induced by

Using natural fibre insulators on green roofs: some considerations

This study focuses on the application of coconut fibre insulators, an insulating material rarely utilized in the Mediterranean context.Despite its undoubted thermal performance, some queries are related with of his thermo-hygrometric behavior.More precisely, during the use of coconut for covering Handheld Vacuum Wheel building for realizing green r
