A SEMI-CLOSED RECIRCULATING SYSTEM FOR THE IN SITU STUDY OF FEEDING AND RESPIRATION OF BENTHIC SUSPENSION FEEDERS

A semi-closed recirculating system for the in situ study of feeding and respiration of benthic suspension feeders

Suspension feeding is one of the most widespread feeding strategies among benthic organisms.However, natural feeding ecology and energetics of benthic suspension feeders are poorly known.The scarcity of field methods, apparatus and protocols that facilitate UHF TV Antenna obtention of reliable in situ data has contributed to this lack of knowledge.

PREDATION OF Boophilus microplus (CANESTRINI, 1887) (ACARI: IXODIDAE) TICK ENGORGED FEMALE BY THE ANT Pachycondyla striata (SMITH, 1858) (HYMENOPTERA: FORMICIDAE) IN PASTURES

Faced with difficulties in the chemical control of Boophilus microplus, this work intended to observe the principal predator of engorged females in pastures of the grass Brachiaria decumbens, at Juiz de Fora, MG, Brazil.A total of 300 engorged female were used, between six experimental repetitions during the winter of 1998 and the summer of 1998/19

Heavy Oil and VAPEX Process: A Brief Review

Heavy oil recovery requires either heat or solvent assistance to reduce its high viscosity Saucepan Set first and then the less viscous oil can be recovered.Processes that use vapor assisted petroleum extraction (VAPEX) utilize vaporized solvent.Solvent vapors are introduced through a top injection well to induce viscosity reduction and the less vi
