ABSTRAK
Phosphorus is an essential element for living organisms. However, an excess loading of phosphorus produces undesirable eutrophication in water bodies. However, different phosphorus species play different roles in the bioavailability and geochemical cycling of phosphorus in the water column. Few studies on the abundance and form of particulate phosphorus have...

ABSTRACT
Optimization and method validation of HPLC with fluorescence detector for the determination of benzo[c]fluorene were studied. The results showed that benzo[c]fluorene had a maximum excitation wavelength at 309 nm and a maximum emission wavelength at 354 nm. The mixture of acetonitrile-water was used as a mobile phase at a ratio...

ABSTRACT
We considered the problem in which a DC motor was controlled to track a given trajectory when the corresponding driven load was associated with uncertain time-varying mass moment of inertia. With the existence of such inertia variation, the corresponding system matrix and input matrix of the control system were simultaneously...

ABSTRACT
Gene-specific markers are important tools in genetic analysis, allowing direct estimation of functional diversity. The goal of this study was to develop intron length polymorphism (ILP) markers from candidate genes associated with the secondary growth related traits that underpin the economics of rubber tree cultivation. We performed a BLAST analysis...

ABSTRACT
Hepatitis B virus (HBV) infects hepatocytes and causes acute and chronic hepatitis that can lead to cirrhosis and hepatocellular carcinoma (HCC) in both animals and humans. Early detection of HBV infection assists in monitoring the patient's response to anti-HBV therapy, blood donation screening, and disease management, control and eradication. This...

ABSTRAK
Using an optimum dynamic scheduling plan, the formulated problem aimed to maximise daily profitability from an existing 12. 5 MW bagasse-based cogeneration plant with a steam capacity of 125 tonne/ h used for sugar refining. The optimal bagasse feed rate yielded a maximum daily profit of 838.49 USD (base case),...

Light-Emitting Diode (LED) lights allow specific wavelengths to be selected. These may be associated with microgreen growth, nitrate accumulation, and synthesis of bioactive compounds. The objective of this study was to assess the effect of LED irradiance on the yield, antioxidant production, and antioxidant capacity of microgreens from five traditional...
