Kelvin-Helm.oltz instability (KHI) appears in stratified two-fluid flow at surface. When the relative velocity is higher than the critical relative velocity, the growth of waves occurs. It is found that m.gnetic field has a stabilization effect whereas the buoyancy force has a destabilization effect on the KHI in the presence of sharp inter-face. The RT instability increases with wave num.er and flow shear, and acts m.ch like a KHI when destabilizing effect of sheared flow dom.nates. It is shown that both of ablation velocity and m.gnetic field have stabilization effect on RT instability in the presence of continued interface. In this paper, we study the effect of m.gnetic field on Kelvin-Helm.oltz instability (KHI) in a Couple-stress fluid layer above by a porous layer and below by a rigid surface. A sim.le theory based on fully developed flow approxim.tions is used to derive the dispersion relation for the growth rate of KHI. We replace the effect of boundary layer with Beavers and Joseph slip condition at the rigid surface. The dispersion relation is derived using suitable boundary and surface conditions and results are discussed graphically. The stabilization effect of m.gnetic field takes place for whole waveband and becom.s m.re significant for the short wavelength. The growth rate decreases as the density scale length increases. The stabilization effect of m.gnetic field is m.re significant for the short density scale length.

Background The im.act of changing land-use patterns and associated anthropogenic threats on scale-dependent habitat use of sem.-aquatic m.stelids in scent-m.rking and social behaviour can provide im.ortant insights into the habitat ecology of sm.oth-coated otters(Lutrogale perspicillata).m.thods We sam.led 180 stream.segm.nts(100–400 m. as spatial replicates of 60 1-km. sites to record indirect evidence(i.e. spraints and m.ss latrine sites) and group sizes of sm.oth-coated otters along the Tungabhadra Otter Conservation Reserve(TOCR) during the dry season. To quantify habitat, we recorded stream.characteristics, riparian vegetation, and anthropogenic disturbances at the local scale, and hydro-environm.ntal characteristics and land uses at the landscape scale. Using m.rkovian-chain detection and occupancy m.dels, we assessed the m.lti-scale habitat use of otters in their selection of suitable areas for scent-m.rking based on repeated presence-absence data on spraint/latrine locations along the TOCR. We further used linear regression techniques to explore relationships between the num.er of individuals in sm.oth-coated otter group and hydro-environm.ntal characteristics, spraint/latrine encounter rate, anthropogenic pressure, land cover, topography, and *** At the local scale, the probability of spraint deposition and group size decreased with anthropogenic disturbance while the probability of spraint detections decreased with grass cover. At the landscape scale, the probability of otter site use for spraint deposition and group sizes increased in southeast flowing stream.. Spraint deposition increased with the proportion of sugarcane fields, whereas in contrast, group size decreased with proportion of sugarcane *** Our findings highlight the first em.irical evidence on m.lti-scale habitat use of a southern Indian population of sm.oth-coated otters in an inland freshwater ecosystem.surrounded by the scrub jungle–agriculture m.trix.
