Plasmodium falciparum is a protozoan parasite that causes an infectious disease known as malaria. P. falciparum is the most severe strain of the malaria species correlated with almost every malarial death. [1] The other 3 species that cause malaria include: P. vivax, P. ovale, and P. malariae.
To set the value of a Boolean attribute, such as disabled, you can specify any value. An empty string or the name of the attribute are recommended values. All that matters is that if the attribute is present at all, regardless of its actual value, its value is considered to be true.
These attributes are the key attributes and range from Primary key (single attribute identifier) to a Composite Key (Multi attribute Identifier). The rest of the attributes after the identifier are considered the non-key attributes or descriptors, which just describe the entity. Example: Above in the table Student there is only one unique identifier, stu_LastName, which is the primary key of the table. The rest of the attributes are descriptors.
