In meteorology, a cloud is an aerosolcomprising a visible mass of minuteliquid droplets, frozen crystals, or particles suspended in theatmosphere above the surface of aplanetary body.[1] The droplets and crystals may be made of water or various chemicals. On Earth, clouds are formed as a result of saturation of the air when it is cooled to its dew point, or when it gains sufficient moisture (usually in the form of water vapor) from an adjacent source to raise the dew point to the ambient temperature. They are seen in the Earth's homosphere (which includes the troposphere, stratosphere, andmesosphere). Nephology is the science of clouds which is undertaken in the cloud physics branch ofmeteorology.
There are two methods of naming clouds in their respective layers of the atmosphere; Latin and common. Cloud types in the troposphere, the atmospheric layer closest to Earth's surface, have Latin names due to the universal adaptation of Luke Howard'snomenclature. Formally proposed in 1802, it became the basis of a modern international system that divides clouds into five physical forms that appear in any or all of three altitudelevels (formerly known as étages). These physical types, in approximate ascending order of convective activity, include stratiform sheets, cirriformwisps and patches, stratocumuliformlayers (mainly structured as rolls, ripples, and patches), cumuliformheaps, and very large cumulonimbiformheaps that often show complex structure. The physical forms are divided by altitude level into ten basic genus-types. The Latin names for applicable high-level genera carry acirro- prefix, and an alto- prefix is added to the names of the mid-level genus-types. Most of the genera can be subdivided into species and further subdivided into varieties.

Unique, dry milkfish pond = unik, empang bandeng kering
A fish pond, or fishpond, is a controlled pond, artificial lake, orreservoir that is stocked with fish and is used in aquaculture for fish farming, or is used for recreational fishing or for ornamental purposes. In themedieval European era it was typical for monasteries and castles (small, partly self-sufficient communities) to have a fish pond.

The domestic cat[1][5] (Felis silvestris catus or Felis catus) is a small, typicallyfurry, carnivorous mammal. They are often called house cats when kept as indoor pets or simply cats when there is no need to distinguish them from other felids and felines.[6] Cats are often valued by humans for companionship and for their ability to hunt vermin. There are more than 70 cat breeds, though different associations proclaim different numbers according to their standards.

Cats are similar in anatomy to the other felids, with a strong flexible body, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. Cat senses fit acrepuscular and predatory ecological niche. Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. They can see in near darkness. Like most other mammals, cats have poorer color vision and a better sense of smell than humans. Cats, despite being solitary hunters, are a social species and cat communication includes the use of a variety of vocalizations (mewing,purring, trilling, hissing, growling, andgrunting), as well as cat pheromonesand types of cat-specific body language.[7]
Cats have a high breeding rate.[8]Under controlled breeding, they can be bred and shown as registeredpedigree pets, a hobby known as cat fancy. Failure to control the breeding of pet cats by neutering, as well as theabandonment of former household pets, has resulted in large numbers offeral cats worldwide, requiringpopulation control.[9] In certain areas outside cats' native range, this has contributed, along with habitat destruction and other factors, to the extinction of many bird species. Cats have been known to extirpate a bird species within specific regions and may have contributed to the extinction of isolated island populations.[10] Cats are thought to be primarily responsible for the extinction of 33 species of birds, and the presence of feral and free-ranging cats makes some otherwise suitable locations unsuitable for attempted species reintroduction.[11]

Unique, fish meal bran = Unik, ikan makan dedak
Rice bran is a byproduct of the rice milling process (the conversion ofbrown rice to white rice), and it contains various antioxidants that impart beneficial effects on human health.[1] A major rice bran fraction contains 12%-13% oil and highlyunsaponifiable components (4.3%).[citation needed] This fraction containstocotrienols (a form of vitamin E), gamma-oryzanol and beta-sitosterol; all these constituents may contribute to the lowering of the plasma levels of the various parameters of the lipid profile. Rice bran also contains a high level of dietary fibres (beta-glucan,pectin and gum). In addition, it also contains ferulic acid, which is also a component of the structure of nonlignified cell walls. However, some research suggests there are levels of inorganic arsenic (a toxin and carcinogen) present in rice bran. One study found the levels to be 20% higher than in drinking water.[2] Other types of bran (derived from wheat, oat or barley) contain less arsenic than rice bran, and are just as nutrient-rich.[3]
