OVARIAN BALLS (FLOATING OVARIES) OF RHADINORHYNCHUS NILOTICUS MOHAMADAIN, 1989 FROM THE NILE PERCH LATES NILOTICUS LINNAEUS, 1758; AN ELECTRON MICROSCOPE STUDY

In Acanthocephala, the ovarian balls (floating ovaries) are distinctive structures found suspended in the fluid-filled metasoma mpu63zm/a of females and are responsible for egg production and maturation.Those structures have not been studied in Rhadinorhynchus niloticus.We aimed to investigate their ultra-structure by means of scanning and transmis

Meeting the challenge of improving rural incomes in Ethiopia will require some form of transformation of the subsistence, low-input and low-productivity farming systems to agricultural commercialization.In the process, commercial production of high value food crops like potato would have been expected.Nonetheless, in the study area, Kombolcha Wored

We consider a heterogeneous MIMO-OFDMA based dense small cell (SC) system in which each here macro cell base station (MBS) serves its coverage area with the help of small cell base stations (SBSs) through multi-hop wireless connections.The SBSs act as integrated access and backhaul (IAB) nodes that handle both access and backhaul traffics with wire
