High Court Of Australia
The High Court of Australia is the apex court of the Australian legal system. It exercises original and appellate jurisdiction on matters specified in the Constitution of Australia and supplementary legislation. The High Court was established following the passage of the ''Judiciary Act 1903'' (Cth). Its authority derives from chapter III of the Australian Constitution, which vests it (and other courts the Parliament creates) with the judicial power of the Commonwealth. Its internal processes are governed by the ''High Court of Australia Act 1979'' (Cth). The court consists of seven justices, including a chief justice, currently Stephen Gageler. Justices of the High Court are appointed by the governor-general on the formal advice of the attorney-general following the approval of the prime minister and Cabinet. They are appointed permanently until their mandatory retirement at age 70, unless they retire earlier. Typically, the court operates by receiving applicati ...

Hillcrest Christian Academy
Hillcrest is a town in the KwaZulu-Natal province of South Africa that forms part of the eThekwini Metropolitan Municipality and is situated approximately 32 km (20 mi) north-west of Durban and 53 km (33 mi) south-east of Pietermaritzburg. History Hillcrest was formerly a sleepy village, governed by its own Town Board on the outskirts of Durban that has now become a booming suburb incorporated into the eThekwini Metropolitan Municipality. ''Hill Crest'' (as the town's name was variously spelt until 1969) was founded on a rise in the main road from Durban to Pietermaritzburg in 1895 as a farming or "weekend" village, then a good distance from what was the emerging port of Port Natal. The village was laid out as leasehold sites on a portion of the farm Albinia owned by William Gillitt, one of the main pioneer families of the area and after which the nearby suburb of Gillitts is named. One of the other early families to set up in the area was the Acutts who had already established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Healthcare Assistant
Unlicensed assistive personnel (UAP) are paraprofessionals who assist individuals with physical disabilities, mental impairments, and other health care needs with their activities of daily living (ADLs). UAPs also provide bedside care—including basic nursing procedures—all under the supervision of a registered nurse, licensed practical nurse or other health care professional. UAPs must demonstrate their ability and competence before gaining any expanded responsibilities in a clinical setting. While providing this care, UAPs offer compassion and patience and are part of the patient's healthcare support system. Communication between UAPs and registered nurses (RNs) is key as they are working together in their patients' best interests. The scope of care UAPs are responsible for is delegated by RNs or other clinical licensed professionals. UAPs care for patients in hospitals, residents of nursing facilities, clients in private homes, and others in need of their services due to ...

HCA (classification)
HCA is a para-cycling classification. Definition In 2008, ''BBC Sport'' defined this classification as "HCA: For athletes with complete loss of trunk and lower limb function" In 2008, the ''Australian Broadcasting Corporation'' defined this classification was "Handcycling (HC): Cyclists in handcycling race on bikes with two big wheels at either end - they sit in the middle and use a hand crank rather than pedals to propel themselves forward. These competitors usually require a wheelchair for mobility or are unable to use normal bikes or tricycles because of severe lower limb disability." The Australian Paralympic Education Program defined this classification in 2012 as: "For athletes with complete loss of trunk and lower limb function" Classification history Cycling first became a Paralympic sport at the 1988 Summer Paralympics. In September 2006, governance for para-cycling passed from the International Paralympic Committee's International Cycling Committee to UCI at a meeting in ...

Car Battery
An automotive battery, or car battery, is a usually 12 Volt lead-acid rechargeable battery that is used to start a motor vehicle, and to power lights, screen wiper etc. while the engine is off. Its main purpose is to provide an electric current to the Starter (engine), electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle. Once the engine is running, power for the car's electrical systems is still supplied by the battery, with the alternator (automotive), alternator charging the battery as demands increase or decrease. Battery in modern cars Gasoline and diesel engine Typically, starting uses less than three percent of the battery capacity. For this reason, automotive batteries are designed to deliver maximum current for a short period of time. They are sometimes referred to as "SLI batteries" for this reason, for starting, lighting and ignition. SLI batteries are not designed for deep dischargi ...

Brilliant (diamond Cut)
A brilliant is a diamond or other gemstone cut in a particular form with 57-58 facets so as to have exceptional brilliance. The word 'brilliant' is also used for a diamond cut in this fashion. The underside is conical, a shape that provides maximal light return through the top of the diamond. Even with modern techniques, the cutting and polishing of a diamond crystal always results in a dramatic loss of weight; rarely is this loss less than 50%. The round brilliant cut is preferred when the crystal is an octahedron, as often two stones may be cut from one such crystal. Oddly-shaped crystals such as macles are more likely to be cut in a '' fancy cut''—that is, a cut other than the round brilliant—which the particular crystal shape lends itself to. Origin and etymology The earliest diamond cutting techniques were simply to polish the natural shape of rough diamonds, often octahedral crystals. Around the 1500s, polishing and cutting inventions made it possible to shape diamond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroxycitric Acid
Hydroxycitric acid (HCA) is a derivative of citric acid that is found in a variety of tropical plants including '' Garcinia cambogia'' and ''Hibiscus sabdariffa''. There are four isomers, (+)- and (-)-hydroxycitric acid, and (+)- and (-)-allo-hydroxycitric acid. The (-)-hydroxycitric acid isomer is the one found in ''Garcinia''. Chemistry Hydroxycitric acid as such cannot be isolated from garcinia fruits or hibiscus sabdariffa fruits. It exists in both the open and lactone forms. The presence of two chiral centres in the molecule is exploited to construct molecular skeletons that are otherwise difficult to synthesize, thus demonstrating the lactones use as chirons. Biological effects (-)-HCA is a competitive inhibitor of ATP citrate lyase, which converts citrate into oxaloacetate and acetyl CoA. The reverse of this conversion is a step in the citric acid cycle. Laboratory and animal studies of HCA have produced results that indicate a potential for modulation of lipid metaboli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Host Channel Adapter
In computer hardware a host controller, host adapter or host bus adapter (HBA) connects a computer system bus which acts as the host system to other network and storage devices. The terms are primarily used to refer to devices for connecting SCSI, SAS, NVMe, Fibre Channel and SATA devices. Devices for connecting to FireWire, USB and other devices may also be called host controllers or host adapters. Host adapters can be integrated in the motherboard or be on a separate expansion card. The term network interface controller (NIC) is more often used for devices connecting to computer networks, while the term converged network adapter can be applied when protocols such as iSCSI or Fibre Channel over Ethernet allow storage and network functionality over the same physical connection. SCSI A connects a host system and a peripheral SCSI device or storage system. These adapters manage service and task communication between the host and target. Typically a device driver, linked to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High Content Analysis
High-content screening (HCS), also known as high-content analysis (HCA) or cellomics, is a method that is used in biological research and drug discovery to identify substances such as small molecules, peptides, or RNAi that alter the phenotype of a cell (biology), cell in a desired manner. Hence high content screening is a type of phenotypic screen conducted in cells involving the analysis of whole cells or components of cells with simultaneous readout of several parameters. HCS is related to high-throughput screening (HTS), in which thousands of compounds are tested in parallel for their activity in one or more biological assays, but involves assays of more complex cellular phenotypes as outputs. Phenotypic changes may include increases or decreases in the production of cellular products such as proteins and/or changes in the Morphology (biology), morphology (visual appearance) of the cell. Hence HCA typically involves automated microscopy and image analysis. Unlike high-content a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hierarchical Cluster Analysis
In data mining and statistics, hierarchical clustering (also called hierarchical cluster analysis or HCA) is a method of cluster analysis that seeks to build a hierarchy of clusters. Strategies for hierarchical clustering generally fall into two categories: * Agglomerative: Agglomerative: Agglomerative clustering, often referred to as a "bottom-up" approach, begins with each data point as an individual cluster. At each step, the algorithm merges the two most similar clusters based on a chosen distance metric (e.g., Euclidean distance) and linkage criterion (e.g., single-linkage, complete-linkage). This process continues until all data points are combined into a single cluster or a stopping criterion is met. Agglomerative methods are more commonly used due to their simplicity and computational efficiency for small to medium-sized datasets . * Divisive: Divisive clustering, known as a "top-down" approach, starts with all data points in a single cluster and recursively splits the clu ...

Heterocyclic Amine
Heterocyclic amines, also sometimes referred to as HCAs, are chemical compounds containing at least one heterocyclic ring, which by definition has atoms of at least two different elements, as well as at least one amine (nitrogen-containing) group. Typically it is a nitrogen atom of an amine group that also makes the ring heterocyclic (e.g., pyridine), though compounds exist in which this is not the case (e.g., the drug zileuton). The biological functions of heterocyclic amines vary, including vitamins and carcinogens. Carcinogenic heterocyclic amines are created by high temperature cooking of meat and smoking of plant matter like tobacco. Some well known heterocyclic amines are niacin (vitamin B3), nicotine (psychoactive alkaloid and recreational drug), and the nucleobases that encode genetic information in DNA. Five-membered heterocyclic amines The compound pyrrolidine is composed of molecules that contain a saturated ring of five atoms. This cyclic structure is composed of o ...
