this experiment was carried out to study the effect of sodium chloride from drinking water and feed intake on the quality of egs from laying hens. four hundred and twenty native and white leghorn laying hens ranging from 36 to 43 weeks of age were used. seven experimental treatments containing different levels of salt supplied by feed and/or drinking water were compared. increasing salt int...

An elastomeric seal may leak by elastic deformation without any material damage. We describe elastic leak using a theoretical model, and watch a seal deform and leak using a transparent experimental setup. The elastomer seals the fluid by forming contact with surroundinghardmaterials. As the fluid pressure increases, the contact stress also increases but not as much. When the fluid pressure sur...

A new approach which differs from the conventional pattern recognition techniques in partitioning a seal imprint image into a triangular tessellation is proposed. The image plane is segmented into a mesh of triangles according to the Delaunay triangulation paradigm, and the distribution of the triangular area is used as the primary feature for matching unrecognized seal imprints with model imag...

В статье приведены результаты метабаркодирования ДНК микробиома респираторного, урогенитального и желудочно-кишечного трактов каспийского тюленя. Показан профиль тюленя отмечено отсутствие возбудителей бактериальных зоонозов в их бета-сообществе микробиотов. The article presents the results of metabarcoding microbiome DNA respiratory, urogenital and gastrointestinal tracts Caspian seal. profile...
