A cleaning device for water sensors was developed in this study. The whole device focuses on two ways: water rotary erosion and ultrasonic cleaning. The upper computer software and lower computer software are developed. The system parameters are set on the touch screen and the upper computer software ...

The current method of raising tilapia in the Philippines is through fish ponds exposed to the weather. Methods for measuring pH, temperature, dissolved oxygen, and ammonia are limited to manually using a chemical test kit. The current system relies on manually regulating the water quality so the fish ...
The increase in demand of power and the depletion of non-renewable sources call for an alternative source of energy. Biodiesel from microalgae is a potential alternative source of energy due to its high lipid content. However, the bulk of the energy requirement to produce biodiesel from microalgae is ...
The Philippines is one of the top producers of seaweed products such as carrageenan. The country's seaweed industry is considered as a major economic contributor to the aquaculture industry. However, the current method of sun drying the seaweeds may still be improved in terms of quality and capacity. ...
Drying is an integral part of seaweed manufacturing process. The Philippines is one of the leading producers of seaweeds in the world. However, due to the lack of development of appropriate technologies, the country is struggling to compete with the quality of seaweed produced internationally. A significant ...
Measurement accuracy is important in any field of study. This work presents the effect of water quality parameters with each other in a controlled aquaculture environment, which can be used to ensure data reliability. The water quality parameters that are considered are temperature, pH and flow rate. ...
Wireless sensor network is widely used in agricultural domain for efficient farming management. The application of the network system for agricultural environment monitoring was successfully developed in this research. Different sensors were integrated for acquiring data of three essential environment ...
This paper addresses the problem of generating a continuous and differentiable trajectory on the Lie group of rigid body motions, se(3), for a class of underactuated vehicles modeled as rigid bodies. The three rotational degrees of freedom (DOF) are independently actuated, while only one translational ...
This research contributes to the improvement of the increasing requirements for the improving the traceability and transparency of fish and fishery products, which are subject of rapid deterioration during the supply chain. The research study the requirements for the fish and fishery products traceability ...
In the international regulation framework, the energy-efficient operation of ships is becoming standard. In this respect, restrictions on new construction appear to encourage improvement to existing vessels often equipped with outdated technologies. One of the relevant aspects of propulsion plant design ...
The oceans absorb ~25% of the annual anthropogenic CO2 emissions. This causes a shift in the marine carbonate chemistry termed ocean acidification (OA). OA is expected to influence metabolic processes in phytoplankton species but it is unclear how the combination of individual physiological changes ...
Alpinia galanga oil (AGO) possesses various activities but low aqueous solubility limits its application particularly in aquatic animals. AGO has powerful activity on fish anesthesia. Ethanol used for enhancing water miscible of AGO always shows severe side effects on fish. The present study explores ...
Threshold effects are common in ecosystems and can generate counterintuitive outcomes in management interventions. A threshold effect proposed for steelhead trout (Oncorhynchus mykiss) is size-conditional smolting and marine survival. Steelhead are anadromous, maturing in the ocean but migrating to ...
Information about the distribution and abundance of the habitat-forming sessile organisms in marine ecosystems is of great importance for conservation and natural resource managers. Spatial interpolation methodologies can be useful to generate this information from in situ sampling points, especially ...
Introduction Zoonotic enteric parasites are ubiquitous and remain a public health threat to humans due to our close relationship with domestic animals and wildlife, inadequate water, sanitation, and hygiene practices and diet. While most communities are now sedentary, nomadic and pastoral populations ...
The goals of this study were to compare the serum chemistry and hematology values of wild and semi-natural free-ranging Yangtze Finless Porpoises (Neophocaena asiaeorientalis ssp. asiaeorientalis) populations and to ascertain how these values change with the different environmental condition. For this ...
Abstract Competition for resources including food, physical space, and potential mates is a fundamental ecological process shaping variation in individual phenotype and fitness. The evolution of competitive ability, in particular social dominance, depends on genetic (co)variation among traits causal ...
Abstract Coastal humanâmade structures, such as marinas and harbors, are expanding worldwide. Species assemblages described from these artificial habitats are novel relative to natural reefs, particularly in terms of the abundance of nonindigenous species ( NIS). Although these fouling assemblages ...
ABSTRACT Here, we present the draft genome sequence of Vibrio splendidus type strain DSM 19640. V. splendidus is an abundant species among coastal vibrioplankton. The assembly resulted in a 5,729,362-bp draft genome with 5,032 protein-coding sequences, 6 rRNAs, and 117 tRNAs.
