A nickel–metal hydride battery is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel-cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium. NiMH batteries can have two to three times the capacity of NiCd batteries of the same size, with significantly higher energy density, although only about half that of lithium-ion batteries.
Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type. This discharge may produce a wide range of electromagnetic radiation, from heat created by the rapid movement of electrons, to brilliant flashes of visible light in the form of black-body radiation. Lightning causes thunder, a sound from the shock wave which develops as gases in the vicinity of the discharge experience a sudden increase in pressure. Lightning occurs commonly during thunderstorms as well as other types of energetic weather systems, but volcanic lightning can also occur during volcanic eruptions. Lightning is an atmospheric electrical phenomenon and contributes to the global atmospheric electrical circuit.
Brine is water with a high-concentration solution of salt. In diverse contexts, brine may refer to the salt solutions ranging from about 3.5% up to about 26%. Brine forms naturally due to evaporation of ground saline water but it is also generated in the mining of sodium chloride. Brine is used for food processing and cooking, for de-icing of roads and other structures, and in a number of technological processes. It is also a by-product of many industrial processes, such as desalination, so it requires wastewater treatment for proper disposal or further utilization.
The nipple is a raised region of tissue on the surface of the breast from which, in females, milk leaves the breast through the lactiferous ducts to breastfeed an infant. The milk can flow through the nipple passively or it can be ejected by smooth muscle contractions that occur along with the ductal system. Male mammals also have nipples but without the same level of function, and often surrounded by body hair.
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor.
A rechargeable battery, storage battery, or secondary cell, is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use. It is composed of one or more electrochemical cells. The term "accumulator" is used as it accumulates and stores energy through a reversible electrochemical reaction. Rechargeable batteries are produced in many different shapes and sizes, ranging from button cells to megawatt systems connected to stabilize an electrical distribution network. Several different combinations of electrode materials and electrolytes are used, including lead–acid, zinc–air, nickel–cadmium (NiCd), nickel–metal hydride (NiMH), lithium-ion (Li-ion), lithium iron phosphate (LiFePO4), and lithium-ion polymer.
A weir or low-head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. There is no single definition as to what constitutes a weir.
Tie-dye is a term used to describe a number of resist dyeing techniques and the resulting dyed products of these processes. The process of tie-dye typically consists of folding, twisting, pleating, or crumpling fabric or a garment, before binding with string or rubber bands, followed by the application of dye or dyes. The manipulations of the fabric before the application of dye are called resists, as they partially or completely prevent ('resist') the applied dye from coloring the fabric. More sophisticated tie-dye may involve additional steps, including an initial application of dye before the resist, multiple sequential dyeing and resist steps, and the use of other types of resists and discharge.
A military discharge is given when a member of the armed forces is released from their obligation to serve. Each country's military has different types of discharge. They are generally based on whether the persons completed their training and then fully and satisfactorily completed their term of service. Other types of discharge are based on factors such as the quality of their service, whether their service had to be ended prematurely due to humanitarian or medical reasons, whether they had been found to have drug or alcohol dependency issues and whether they were complying with treatment and counseling, and whether they had demerits or punishments for infractions or were convicted of any crimes. These factors affect whether they will be asked or allowed to re-enlist and whether they qualify for benefits after their discharge.
Demobilization or demobilisation is the process of standing down a nation's armed forces from combat-ready status. This may be as a result of victory in war, or because a crisis has been peacefully resolved and military force is no longer necessary. The opposite of demobilization is mobilization, which is the act of calling up forces for active military service. Forceful demobilization of a defeated enemy is called demilitarization.
In the US armed forces, separation means that a person is leaving active duty but not necessarily the service entirely. Separation typically occurs when someone reaches the date of their Expiration of Term of Service (ETS) and are released from active duty, but still must complete their military reserve obligations. Upon separation, they receive Form DD214, which verifies their military service.
Vaginal discharge is a mixture of liquid, cells, and bacteria that lubricate and protect the vagina. This mixture is constantly produced by the cells of the vagina and cervix, and it exits the body through the vaginal opening. The composition, amount, and quality of discharge varies between individuals and can vary throughout the menstrual cycle and throughout the stages of sexual and reproductive development. Normal vaginal discharge may have a thin, watery consistency or a thick, sticky consistency, and it may be clear or white in color. Normal vaginal discharge may be large in volume but typically does not have a strong odor, nor is it typically associated with itching or pain. While most discharge is considered physiologic or represents normal functioning of the body, some changes in discharge can reflect infection or other pathological processes. Infections that may cause changes in vaginal discharge include vaginal yeast infections, bacterial vaginosis, and sexually transmitted infections. The characteristics of abnormal vaginal discharge vary depending on the cause, but common features include a change in color, a foul odor, and associated symptoms such as itching, burning, pelvic pain, or pain during sexual intercourse.
East Canada Creek is a 34.6-mile-long (55.7 km) river in upstate New York, United States. It is a tributary of the Mohawk River and flows southward from New York's Adirondack Park. The name "Canada" may be derived from the St. Lawrence Iroquoian word Kanata, meaning "village"; the name may also refer to the creek's importance as a trail to Canada in colonial times.
The Haraz River is a notable river flowing through the Mazandaran Province of northern Iran. It flows northwards, from the Alborz mountain range into the Caspian Sea. After flowing along the Haraz Road and Valley for about 100 km, the Haraz river meanders in the midst of Amol, from where it reaches the Caspian Sea. The Haraz begins in Mount Damavand and flows northward and pours into Caspian Sea in the area between the two northern cities of Mahmoudabad and Fereydunkenar. The Haraz is currently contaminated due to discharge of effluent from various industrial plants.
Karl Stoerk was an Austrian laryngologist who was a native of Ofen.
Meandu Creek Dam is a dam built near Yarraman in Queensland, Australia. The Tarong and Tarong North Power Stations source water from the Brisbane River catchment via a pipeline from Wivenhoe Dam. Cooling tower blowdown water is either discharged directly to Tarong Energy's Meandu Creek Dam or supplied to the nearby Tarong Mine owned by Rio Tinto Coal Australia. Excess water from the mine is discharged back to Meandu Creek Dam. Releases from Meandu Creek Dam supply downstream irrigators on Meandu Creek. In 2019 Stanwell Corporation temporarily stopped discharges into the creek to allow downstream property owners to repair culverts.
An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell.
Plasma is one of four fundamental states of matter characterized by the presence of a significant portion of charged particles in any combination of ions or electrons. It is the most abundant form of ordinary matter in the universe, mostly in stars, but also dominating the rarefied intracluster medium and intergalactic medium. Plasma can be artificially generated, for example, by heating a neutral gas or subjecting it to a strong electromagnetic field.
Blennorrhoea aka blennorrhagia or myxorrhoea, is a medical term denoting an excessive discharge of watery mucus, especially from the urethra or the vagina, and also used in ophthalmology for an abnormal discharge from the eye, but now regarded as a synonym for conjunctivitis and accordingly rarely used.
Nanu Oya is a 27 km (17 mi) long stream in the Central Province of Sri Lanka. It originates at an elevation of over 2,000 m (6,562 ft) on Pidurutalagala, the highest mountain in Sri Lanka, flowing into the Kotmale Oya at an elevation of approximately 1,200 m (3,937 ft). The Kotmale Oya is a tributary of the Mahaweli River, the longest river in Sri Lanka, which finally discharges at Trincomalee after a combined distance of nearly 350 km (217 mi). The river was dammed in 1873 to create the popular Lake Gregory in Nuwara Eliya. The Nanu Oya discharges into the Kotmale Oya 2.5 km (1.6 mi) upstream of the Upper Kotmale Dam.
