National health insurance (NHI), sometimes called statutory health insurance (SHI), is a system of health insurance that insures a national population against the costs of health care. It may be administered by the public sector, the private sector, or a combination of both. Funding mechanisms vary with the particular program and country.
According to some experts, such as Uwe Reinhardt, [139] Sherry Glied, Megan Laugensen, [140] Michael Porter, and Elizabeth Teisberg, [141] this pricing system is highly inefficient and is a major cause of rising health care costs. Health care costs in the United States vary enormously between plans and geographical regions, even when input ...
Myrmecotrophy, meaning "ant-fed," is the ability of plants to absorb nutrients from debris piles left by ant nests or, in the case of Nepenthes bicalcarata, from ant egesta. [13] The tropical tree Cecropia peltata obtains 98% of its nitrogen from the waste deposited by its ant counterparts.
A list of countries by health insurance coverage. The table lists the percentage of the total population covered by total public and primary private health insurance, by government/social health insurance, and by primary private health insurance, including 34 members of Organisation for Economic Co-operation and Development (OECD) member countries.
Some chemical defenses once thought to be produced by the plant have since been shown to be synthesized by endophytic fungi. The chemical basis of insect resistance in endophyte-plant defense mutualisms has been most extensively studied in the perennial ryegrass and three major classes of secondary metabolites are found: indole diterpenes, ergot alkaloids and peramine.
Based on our research, Lemonade, Allstate and Auto-Owners offer some great homeowners insurance options. Unlike a rodent or ant infestation, it can be difficult to detect termites, which live in ...
Health insurance costs are a major factor in access to health coverage in the United States. The rising cost of health insurance leads more consumers to go without coverage [1] and increase in insurance cost and accompanying rise in the cost of health care expenses has led health insurers to provide more policies with higher deductibles and other limitations that require the consumer to pay a ...
Finally, current work focusing on ants' role in nutrient supplementation for plants has shown that in many ant-plant relationships, nutrient flow is bidirectional. One study has estimated that while 80% of the carbon in the bodies of Azteca spp. workers is supplied by the host tree ( Cecropia spp.), 90% of the Cecropia tree's nitrogen was ...
