Plural nouns refer to multiple individuals, animals or things. Most nouns have both singular and plural forms.
Most nouns form plurals by adding an -s or -es to the end. However, some words may not follow these rules exactly and change spelling when transformed into a plural noun.
They are a source of Vitamin D
Vitamin D is an essential nutrient that aids calcium absorption in the body and supports bone growth. It also strengthens the immune system and fights infection. Your body can obtain this vital nutrient through exposure to sunlight, foods, or supplements.
Vitamin D deficiency can cause rickets in children and osteomalacia (softening of bones) in adults, leading to pain and weakness in the bones as well as an increased risk for fractures.
Vitamin D is primarily obtained through sunlight. The UV rays from the sun help your skin produce vitamin D, and depending on your location and time of year you may be able to get enough by spending 20 minutes daily outside in the sunlight.
Other sources of vitamin D include eating fatty fish and mushrooms. Certain varieties, such as maitake or dried shiitake mushrooms, are particularly high in this vitamin due to their plant sterols that convert ultraviolet (UV) light into usable form for your body.
Vitamin D can be obtained through fortified milk, orange juice and other enriched food sources. It’s also available in pills or liquid supplements. For optimal absorption of this nutrient, take it with fat like ghee, coconut oil, nuts seeds and eggs.
According to the Food and Nutrition Board of the National Institutes of Health, adults should consume 600 international units (IU) daily; older adults should consume 800 IU. Children 1-3 years old should consume 50 IU or less daily, and infants under 12 months shouldn’t exceed 25 IU per day.
Your doctor can give you a blood test to check your current vitamin D levels, giving you an indication of whether or not it is necessary to increase your daily intake. Alternatively, ask them to suggest taking a multivitamin with added vitamin D which are usually available at most health food stores.
They are a source of phosphor
Phosphorus is an element that occurs naturally in many forms. It’s a staple of soil and essential for plant growth, helping it stay strong and healthy.
Hexavalent chromium is a highly reactive element that spontaneously ignites when exposed to oxygen, making it ideal for use in incendiary devices.
Phosphate is essential to the human body for cells to work optimally. It can be found in dairy products, meats and vegetables. Phosphorus plays an essential role in producing ATP – the preferred energy source for numerous physiological processes.
Phosphate-rich foods include cooked rice, cheese, eggs, beans, nuts, fish and poultry. Additionally, it’s found in various processed items like baked goods, cereals, sodas and prepared iced tea mixes.
Studies have demonstrated that the body’s levels of phosphorus are carefully managed by the kidneys and intestines. When these organs detect low phosphate levels or inadequate absorption, they will respond by excreting less phosphorus from urine and increasing phosphorus absorption through the digestive tract.
Dietary supplements often contain phosphorus in the form of phosphate salts (like dipotassium phosphate or disodium phosphate) and phospholipids like phosphatidylcholine or phosphatidylserine.
There are also some multivitamin/multimineral products that contain phosphorus. On average, these provide 10% or less of the Daily Value (DV) for this mineral, though a few deliver more than 100%.
Phosphate is the primary source of dietary phosphorus and it can be obtained mainly from soil sources, animal foods and processed foods. Foods may be classified as organic or inorganic depending on where it comes from and how much phosphate they contain.
Organic phosphate refers to phosphorus bound up with various phosphate esters [1, 2], while inorganic phosphate refers solely to minerals found in biological systems. Apatite rocks (CaF or hydroxylapatite) contain predominantly fluorine as their name implies.
Phosphorus is an essential nutrient for most plants, yet it can be hard to get enough from food sources. For optimal plant growth, pH levels between 5.5-6.5 should be maintained; this range allows phosphorus adsorption by some mineral salts at higher phosphate concentrations, explaining why research has revealed that overuse of phosphate fertilizer may actually have detrimental effects as it increases phosphorus availability in media while blocking other essential nutrients from being absorbed by plants.
They are a source of luminescence
Luminescent material refers to any substance that emits light through the conversion of radiation from its primary spectrum. Common luminescent materials used for this purpose include bioluminescence, chemiluminescence, electrochemiluminescence and electroluminescence.
One way to create luminescence is through doping. Doping increases the intensity of a luminescent material by applying a solution containing that material onto a ceramic body made from yttrium aluminum garnet that has then been heat treated.
Another method for producing luminescent material involves embedding the luminescent material in a matrix of powder particles. The particles can be embedded in epoxy resin or inorganic glass with a low melting point, serving both as an aggregate for the powder particles and scattering center for primary radiation and secondary radiation.
The doped yttrium aluminum garnet absorbs primary radiation and emits secondary radiation in the form of yellow light, depending on its cerium concentration and position within the garnet. This luminescent material can be used for various purposes such as a light source or sensor for bioluminescence.
