Occipital Epilepsy
Occipital epilepsy is a neurological disorder that arises from excessive neural activity in the occipital lobe of the brain that may or may not be symptomatic. Occipital lobe epilepsy is fairly rare, and may sometimes be misdiagnosed as migraine when symptomatic. Epileptic seizures are the result of synchronized neural activity that is excessive, and may stem from a failure of inhibitory neurons to regulate properly. It is a disorder with focal seizures in the occipital lobe of the brain. There are two main types of this epilepsy, each consisting of focal seizures- Gastaut and Panayiotopoulos (Pan.). Other names for the Gastaut type include benign epilepsy of childhood with occipital paroxysms (BECOP) and late-onset occipital epilepsy. Pan. is also known as self-limiting focal epilepsy of childhood with occipital paroxysms and early-onset benign partial epilepsy with occipital paroxysms. There may be no known cause of this type of seizure, but these epilepsies may occur for a variety of reasons, such as brain tumors, infection, trauma and lesions, and idiopathic onset. Seizures originate in the occipital lobe and account for 5 to 10 percent of all epileptic seizure types. Generally, this type of epilepsy can have an onset anywhere from 1–17 years old in children, but the patient prognosis is good. Since the event is located in the occipital lobe, symptoms may occur spontaneously and include visual stimuli.

Toophan
The Toophan (Persian: طوفان‎ "Storm", rarely Toofan) is an Iranian SACLOS anti-tank guided missile reverse-engineered from the United States of America BGM-71 TOW missile. The Toophan 1, an unlicensed copy of the BGM-71A TOW missile, began mass production in 1988 and the Toophan 2, a BGM-71C ITOW variant, was publicly shown in 2000. The Toophan comes in at least 11 variants, many of which are poorly documented, including variants with laser guidance, thermobaric warheads, and tandem-warheads with increased penetration. The Toophan is manufactured jointly by the Aerospace Industries Organization of Iran and Iran Electronics Industries. It's normally deployed from ground-based tripods, and can also be mounted on fighting vehicles and helicopters. Like the BGM-71 TOW missile, the Toophan is a large, rugged, powerful, and reliable anti-tank guided missile deployed by small teams against tanks, armored vehicles, buildings, and other targets. The Toophan forms the backbone of the Iranian Armed Forces's ATGM inventory and is procured in large quantities in a variety of variants. The Toophan has been exported to the governments of Iraq and Syria and to a large number of non-state actors in the Middle East, and has been used in the Iran–Iraq War, the 2006 Lebanon War and the Iraqi, Syrian, and Yemeni Civil Wars.

Abiraterone
Abiraterone, also known as abiraterone acetate and sold under the brand name Zytiga among others, is a medication used to treat prostate cancer. Specifically it is used together with corticosteroid for metastatic castration-resistant prostate cancer (mCRPC) and metastatic high-risk castration-sensitive prostate cancer (mCSPC). It should either be used following removal of the testicles or along with a gonadotropin-releasing hormone (GnRH) analog. It is taken by mouth. Common side effects include tiredness, vomiting, headache, joint pain, high blood pressure, swelling, low blood potassium, high blood sugar, hot flashes, diarrhea, and cough. Other severe side effects may include liver failure and adrenocortical insufficiency. In males who partners can become pregnant, birth control is recommended. Supplied as abiraterone acetate it is converted in the body to abiraterone. Abiraterone works by suppressing the production of androgens – specifically it inhibits CYP17A1 – and thereby decreases the production of testosterone. In doing so, it prevents the effects of these hormones in prostate cancer. Abiraterone was described in 1995, and approved for medical use in the United States and Europe in 2011. It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system. In the United Kingdom it costs the NHS £2,735 a month as of 2018. In the United States this amount costs US$3,276 as of 2019. The medication is marketed widely throughout the world.

NanoRacks CubeSat Deployer
The NanoRacks CubeSat Deployer (NRCSD) is a device to deploy CubeSats into orbit from the International Space Station. Currently, there are two CubeSat deployers on board the International Space Station (ISS): The Japanese Experiment Module (JEM) Small Satellite Orbital Deployer (J-SSOD) and the NanoRacks CubeSat Deployer (NRCSD). The J-SSOD is the first of its kind to deploy small satellites from the International Space Station. The NRCSD is the first commercially operated small satellite deployer from the ISS, maximizing full capabilities of each airlock cycle of deployments. CubeSats belong to a class of research spacecraft called nanosatellites. The basic cube-shaped satellites measure 10 centimeters (3.9 in) on each side, weigh less than 3 pounds (1.4 kg), and have a volume of about 1 liter (0.22 imp gal; 0.26 U.S. gal), although there are CubeSats which are built and deployed with sizes of multiples of 10 cm in length. (As of 2014), one method of getting CubeSats to orbit is to transport them aboard a larger spacecraft as part of a cargo load to a larger space station. When this is done, deploying the CubeSats into orbit as a separate artificial satellite requires a special apparatus, such as the NanoRacks CubeSat Deployer. The NRCSD is put into position to be grabbed by one of the ISS's robotic arms, which then places the CubeSat deployer into the correct position externally mounted to the ISS to be able to release the miniature satellites into proper orbit.

Bertielliasis
Bertielliasis is the infection of Bertiella, a cestode tapeworm parasite that primarily infects nonhuman primates, rodents and Australia n marsupials. Occasionally, human infections have been documented by one of two species: Bertiella studeri, or Bertiella mucronata. Of 29 different Bertiella species, only these two can infect humans. These infections present with symptoms similar to most tapeworm cases, and are frequently misdiagnosed. Bertiella transmission is through oribatid mites that are often present in the soil of problem areas, and can be easily prevented by avoiding contact with nonhuman primates, rodents and soil in these areas.

Phosphate Minerals
Phosphate minerals contain the tetrahedrally coordinated phosphate (PO43−) anion along sometimes with arsenate (AsO43−) and vanadate (VO43−) substitutions. Chlorine (Cl−), fluorine (F−), and hydroxide (OH−) anions that also fit into the crystal structure. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.
