Permintaan benih bening lobster (BBL) untuk keperluan budi daya baik ekspor maupun dalam negeri masih terus meningkat. Kabupaten Banyuwangi merupakan salah satu penghasil BBL di Indonesia. Penelitian ini bertujuan menganalisis karakteristik sosial ekonomi nelayan dan permasalahan usaha penangkapan serta mengkaji peluang pengembangan pemanfaatan Banyuwangi. Metode pengumpulan data dilakukan mela...

A mechanism for the generation of subsurface cyclones and jets when a warm ring smashes onto a continental slope and shelf is proposed based on the results of a primitive-equation three-dimensional numerical model. The warm ring initially ‘sits’ over a slope with an adjoining shelf in a periodic channel, and its subsequent evolution is examined. The ‘inviscid’ response is cyclonic ‘peeling-off’...

There is controversy as to whether homologues from the peripheral subunit binding domain family of small proteins fold ‘downhill’ (that is, non-cooperatively, in the absence of free-energy barriers between conformations) and whether they modulate their size for biological function. Sadqi et al. claim that Naf-BBL — a naphthylalaninelabelled, truncated version of this domain — folds in this way,...

This paper presents the potentials and costs of synthetic fuels (synfuels) produced by renewable energy via PEM water electrolysis subsequent Fischer–Tropsch process for years 2020, 2030, 2040, 2050 in selected countries across globe. The potential was determined open-source tool pyGRETA includes photovoltaic, onshore wind, biomass. Carbon dioxide is obtained from biomass atmosphere direct air ...

Abstract We study asymptotic reductions and solitary waves of a weakly nonlocal defocusing nonlinear Schrödinger (NLS) model. The hydrodynamic form the latter is analyzed by means multiscale expansion methods. To leading-order approximation (where only first moments response function present), we show that waves, in dark solitons, are governed an effective Boussinesq/Benney–Luke (BBL) equation,...

The long term goal of this work is to develop a fundamental understanding and predictive capability of the underlying physics of the interaction of nonlinear internal waves (NLIWs) with the continental shelf seafloor over a broad range of environmental conditions. We are particularly interested in how such interactions impact underwater optics and acoustics and shelf energetics and ecology by s...

During production from oil wells, the deposition of asphaltene and wax at surface facilities porous media is one major operational challenges. The crude rate significantly reduced due to inside reservoir. In addition, these solids costly companies. this study, efficiency different solvents in dissolving was investigated through static dynamic tests. analysis solid deposits choke Iranian carbona...

Abstract Current-topography interactions in the ocean give rise to eddies spanning a wide range of spatial and temporal scales. Latest modeling efforts indicate that coastal underwater topography are important generation sites for submesoscale coherent vortices (SCVs), characterized by horizontal scales (0.1 – 10) km. Using idealized, BBL-resolving simulations adopting an integrated vorticity b...
