Ikan hiu adalah jenis ikan bertulang rawan (Elasmobranchii) yang berperan sebagai predator puncak dalam rantai makanan dan juga memiliki peranan penting dalam menjaga keseimbangan ekosistem di lautan.Saat ini, keberadaan hiu terancam punah akibat aktivitas penangkapan berlebih yang disebabkan meningkatnya permintaan komoditas sirip di pasar interna
This research has studied the possibility of optimizing some of the properties of the precast concrete flags by using by-products of steel fragments from the CNC machines and local slag, the combined influence of these materials338with the water reducing agent.The local slag is produced by the blast furnace from the scrap as a raw material, which i
Abstract Background The extent to which selection determines interspecific patterns of genetic exchange enlightens the role of adaptation in evolution and speciation.Often reported extensive interspecific introgression could be selection-driven, but also result from demographic processes, especially in All Costumes cases of invasive species replace
The slot opening function, also called relative air gap permeance, is a function which, multiplied by the flux density distribution of a slotless geometry, gives the flux density distribution of a slotted configuration.Here, the magnetic field inside the air gap of a multi-slot surface facing a smooth one was studied, by solving the Laplace equatio
