Having a high water cut reduces the economic viability of oil production.Water production increases, as less-viscous water tends to flow through high-permeability zones, leaving behind large volumes of unswept oil.Since the 1920s, different materials have been used in order to plug high-permeability thief zones.Gels Equipment Stands are often prefe
Satellite DNA (satDNA) is one of the major fractions of the eukaryotic nuclear genome.Highly variable satDNA is involved in various genome functions, and a clear link between satellites and phenotypes exists in a wide range of organisms.However, little is known about the origin and temporal dynamics of satDNA.The "library hypothesis" indicates that
Sea cucumbers are considered a traditional food delicacy in Asian countries.In last decades high market demand, uncontrolled exploitation and inadequate management have led to stock overexploitation, driving commercial interest in new target species and new areas.In recent years, Mediterranean and North-East Atlantic sea cucumbers have become fishi
RNAi targeting the electron transport chain has been proven to prolong life span in many different species, and experiments specifically with Drosophila melanogaster and Caenorhabditis elegans have shown a distinct role for neurons.To determine which subset of neurons is implicated in this life span extension, we used the GAL4/UAS system to activat
