In recent decade, aquaculture species, including fish are under danger from bio-aggressors like viruses, bacteria, parasites and fungi. These organisms harm either spontaneously or through aquatic animal husbandry practices or both. The chemicals employed in aquaculture are drugs like antibiotics used to treat diseases, chemicals introduced through

The purpose of this research is to optimize the immobilization of lipase from the viscera of channel catfish to magnetic nanoparticles (MNP-lipase) using CLEA technology, forming a new immobilized enzyme. Lipase was obtained from the viscera of channel catfish, using ammonium sulfate to salt it out. Magnetic nanoparticles were obtained using the co

The purpose of this research is to optimize the functionalization process of magnetic iron oxide nanoparticles for CLEA immobilization to enzymes, as a solution to the present challenges of CLEA technology such as clumping. A co-precipitation method was used to synthesize the magnetic nanoparticles (MNP), in which ferric chloride (FeCl3.6H2O) and f

Experimental studies were conducted in sudden expansion axi-symmetric passage for controlling base pressure and their outputs were showcased in current paper. Micro jet active control techniques are used for controlling base pressure. These controls constitute four spaces around base and symmetric to nozzle axis. Mach numbers of the abruptly expand

The Pusu River has been receiving increased pollution loads because of a significant amount of land-clearing activities for development projects. A total of 113 numbers of fishes belonging to six species under six families were recorded from Pusu River throughout the study period (November 2014–March 2015). The most dominant species were Barbonym

This paper proposes an enhanced gain saturation model of nonlinear semiconductor optical amplifiers (SOAs) by incorporating material-dependent gain compression factor. The rate equations are utilized with the extra gain compression term for Indium-Gallium-Arsenide material-based SOA to account for the steep relaxation oscillations behaviour of nonl

Compressible flow in a suddenly expanded square duct was investigated experimentally to assess the effectiveness of the passive control in the form of the cavities. The flow parameters studied were the Mach number, nozzle pressure ratio, L/W ratio, and area ratio. The test were conducted for multiple cavities and without multiple cavities. From exp

Recognition of foreign object debris (FOD) on ruwanys is mandatory to avert the accidents and emergency. The accurate and precise estimation of FOD is very complex because of the intricated shape and their different tiny sizes as well which are noe easily visilble. For the prompt removal of the FOD from the runways a robust, accurate and precise sy

The provision of affordable and sustainable living has become one of the biggest challenges to rural and marginalized people where access to electricity is prohibitively expensive. The conventional energy generation and the sole nature of fossil fuels have promoted the use of renewable energy methods. There are various categories of renewable and n

The design for UAV was planned taking into account the real-life engineering problems such as different phases involved in developing a product. Here the task is to design, create, build and test a remote-control airplane. The planning and designing of an aircraft must start from the scratch, with lots of restrictions and parameters, like a specifi
