Flowing through the municipalities of Järfälla, Stockholm, Sundbyberg, and Solna, it empties in the bay Bällstaviken, the innermost part of Ulvsundasjön. Some 1,4 km of the stream is passing through culverts and long stretches of it have been straitened out to form part of the local stormwater system. Notwithstanding, other sections are furnished with promenades and ponds and therefore considered as of local recreational interest. The municipalities sharing the catchment area, together with the county administrative board, are collaborating to improve water quality and the areas surrounding the stream.Bällstaån Catchment area Flowing from Viksjö in Järfälla, the stream starts as a ditch receiving considerable amounts of stormwater from the residential area Jakobsberg.

Aquatic Plant
Aquatic plants, also referred to as hydrophytes, are vascular plants and Non-vascular plant, non-vascular plants that have adapted to live in aquatic ecosystem, aquatic environments (marine ecosystem, saltwater or freshwater ecosystem, freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate (marine biology), substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include Nymphaeaceae, waterlily, Nelumbo, lotus, duckweeds, mosquito fern, floating heart, water milfoils, Hippuris, mare's tail, water lettuce, water hyacinth, and algae. Aquatic plants require special adaptation (biology), adaptations for prolonged inundation in water, and for buoyancy, floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrogen
Nitrogen is a chemical element; it has Symbol (chemistry), symbol N and atomic number 7. Nitrogen is a Nonmetal (chemistry), nonmetal and the lightest member of pnictogen, group 15 of the periodic table, often called the Pnictogen, pnictogens. It is a common element in the universe, estimated at Abundance of the chemical elements, seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element chemical bond, bond to form N2, a colourless and odourless diatomic molecule, diatomic gas. N2 forms about 78% of Atmosphere of Earth, Earth's atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time. The name was suggested by French chemist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphorus
Phosphorus is a chemical element; it has Chemical symbol, symbol P and atomic number 15. All elemental forms of phosphorus are highly Reactivity (chemistry), reactive and are therefore never found in nature. They can nevertheless be prepared artificially, the two most common allotropes being white phosphorus and red phosphorus. With as its only stable isotope, phosphorus has an occurrence in Earth's crust of about 0.1%, generally as phosphate rock. A member of the pnictogen family, phosphorus readily forms a wide variety of organic compound, organic and inorganic compound, inorganic compounds, with as its main oxidation states +5, +3 and −3. The isolation of white phosphorus in 1669 by Hennig Brand marked the scientific community's first discovery since Antiquity of an element. The name phosphorus is a reference to the Phosphorus (morning star), god of the Morning star in Greek mythology, inspired by the faint glow of white phosphorus when exposed to oxygen.

Harness Racing
Harness racing is a form of horse racing in which the horses race at a specific gait (a trot or a pace). They usually pull a two-wheeled cart called a sulky, spider, or chariot occupied by a driver. In Europe, and less frequently in Australia and New Zealand, races with jockeys riding directly on saddled trotters ( in French) are also conducted. Breeds In North America, harness races are restricted to Standardbred horses, although European racehorses may also be French Trotters or Russian Trotters, or have mixed ancestry with lineages from multiple breeds. Orlov Trotters race separately in Russia. The light cold-blooded Coldblood trotters and Finnhorses race separately in Finland, Norway and Sweden. Standardbreds are so named because in the early years of the Standardbred stud book, only horses who could trot or pace a mile in a ''standard'' time (or whose progeny could do so) of no more than 2 minutes, 30 seconds were admitted to the book. The horses have proportiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
