White-tip reef sharks are common inhabitants of the shallow waters surrounding the Galapagos Islands, where several known aggregation sites have become touristic attractions. With the aim to describe site fidelity and residency patterns of the white-tip reef sharks in a saltwater creek, we used the ultrasonic telemetry method. The study was undertaken in a saltwater channel South of Academy Bay...

Abstract The magneto-optical (transmittance, absorbance, and reflectance) characteristics of water saltwater in the presence a magnetic field (0T to 0.880T) are investigated this study. authors studies Raman spectra shift response fields. In case water, transmittance is high field, but saltwater, low at wavelength spectrum. was found be 0.7 percent higher 0.88T than absence 651nm–655.67nm. Simi...

Saltwater intrusion into coastal aquifers presents a significant global challenge to fresh groundwater resources. Numerical modelling represents valuable tool study this phenomenon. Darcy’s Law is widely applied studies and extended the Brinkman Equation account for kinetic dissipations due viscous shear. However, their comparative performance accuracy in density-driven flows remain unclear. To...

Studies on hydromineral balance in fishes frequently employ measurements of electrolytes following euthanasia. We tested the effects of fresh- or salt-water euthanasia baths of tricaine mesylate (MS-222) on plasma magnesium (Mg(2+)) and sodium (Na(+)) ions, cortisol and osmolality in fish exposed to saltwater challenges, and the ion and steroid hormone fluctuations over time following euthanasi...

UNLABELLED Nutritional factors are known to be important in the development of different metabolic diseases. The history of nodular or diffuse goiter is closely related to risk of thyroid carcinoma. On account of the function of the thyroid gland, many studies focus on iodine intake. The aim of the study was to assess whether dietary patterns could be risk factors of differentiated thyroid c...
