A screwdriver is a tool, manual or powered, used for turning screws. A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. This form of the screwdriver has been replaced in many workplaces and homes with a more modern and versatile tool, a power drill, as they are quicker, easier, and can also drill holes. The shaft is usually made of tough steel to resist bending or twisting. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw—or ridged or treated for additional 'grip'. Handles are typically wood, metal, or plastic and usually hexagonal, square, or oval in cross-section to improve grip and prevent the tool from rolling when set down. Some manual screwdrivers have interchangeable tips that fit into a socket on the end of the shaft and are held in mechanically or magnetically. These often have a hollow handle that contains various types and sizes of tips, and a reversible ratchet action that allows multiple full turns without repositioning the tip or the user's hand.
The pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. It has two layers, an outer layer made of strong connective tissue, and an inner layer made of serous membrane. It encloses the pericardial cavity, which contains pericardial fluid, and defines the middle mediastinum. It separates the heart from interference of other structures, protects it against infection and blunt trauma, and lubricates the heart's movements.
In the United States, a recess appointment is an appointment by the president of a federal official when the U.S. Senate is in recess. Under the U.S. Constitution's Appointments Clause, the President is empowered to nominate, and with the advice and consent (confirmation) of the Senate, make appointments to high-level policy-making positions in federal departments, agencies, boards, and commissions, as well as to the federal judiciary. A recess appointment under Article II, Section 2, Clause 3 of the Constitution is an alternative method of appointing officials that allows the temporary filling of offices during periods when the Senate is not in session. It was anticipated that the Senate would be away for months at a time, so the ability to fill vacancies in important positions when the Senate is in recess and unavailable to provide advice and consent was deemed essential to maintain government function, as described by Alexander Hamilton in No. 67 of The Federalist Papers.

Royal Bank Plaza is a skyscraper in Toronto, Ontario, Canada that serves as the "corporate headquarters" for the Royal Bank of Canada.

Recess is an American animated television series created by Paul Germain and Joe Ansolabehere and produced by Walt Disney Television Animation, with animation done by Grimsaem, Anivision, Plus One Animation, Sunwoo Animation, and Toon City. The series focuses on six elementary school students and their interaction with other classmates and teachers. The title refers to the recess period during the daily schedule, in the North American tradition of educational schooling, when students are not in lessons and are outside in the schoolyard. During recess, the children form their own society, complete with government and a class structure, set against the backdrop of a regular school.
Recess is a general term for a period in which a group of people are temporarily dismissed from their duties.
The Santoku bōchō or Bunka bōchō (文化包丁) is a general-purpose kitchen knife originating in Japan. Its blade is typically between 13 and 20 cm long, and has a flat edge and a sheepsfoot blade that curves down an angle approaching 60 degrees at the point. The term Santoku may refer to the wide variety of ingredients that the knife can handle: meat, fish and vegetables, or to the tasks it can perform: slicing, chopping and dicing, either interpretation indicating a multi-use, general-purpose kitchen knife. The Santoku's blade and handle are designed to work in harmony by matching the blade's width and weight to the weight of the tang and the handle.
The tympanic cavity is a small cavity surrounding the bones of the middle ear. Within it sit the ossicles, three small bones that transmit vibrations used in the detection of sound.
In firearms operating systems, the term roller locked refers to locking the bolt with rollers. Notable examples of firearms using this method are the MG 42 general-purpose machine gun, and the CZ 52 semi-automatic pistol. It was also applied in the experimental Gerät 03 semi-automatic rifle and Gerät 06 and EM-1 experimental assault rifles. The MG 42's lineage continued past World War II, forming the basis for the nearly identical MG1, chambered in 7.62×51mm NATO, which subsequently evolved into the MG1A3, and later the Bundeswehr's MG 3, Italian MG 42/59 and Austrian MG 74. It also spawned the Yugoslav unlicensed nearly identical Zastava M53.
The cerebellopontine angle (CPA) is located between the cerebellum and the pons. The cerebellopontine angle is the site of the cerebellopontine angle cistern one of the subarachnoid cisterns that contains cerebrospinal fluid, arachnoid tissue, cranial nerves, and associated vessels. The cerebellopontine angle is also the site of a set of neurological disorders known as the cerebellopontine angle syndrome.
Recess Records is an independent record label founded in 1988. Label founder Todd Congelliere initially made 100 cassettes of F.Y.P's songs and sold them at skateboard contests. Two years later, Congelliere released a vinyl record, F.Y.P's Extra Credit, an 11-song 7-inch record, and the label took off from there.
The costodiaphragmatic recess, also called the costophrenic recess or phrenicocostal sinus, is the posterolateral fringe of the pleural space, a potential space around the lung inside the pleural cavity. It is located at the acutely angled junction ("reflection") between the costal and diaphragmatic parietal pleurae, and is interpreted two-dimensionally on plain X-rays as the costophrenic angle. It measures approximately 5 cm (2.0 in) vertically and extends from the eighth to the tenth rib along the mid-axillary line.
The costomediastinal recess is a potential space at the border of the mediastinal pleura and the costal pleura. It assists lung expansion during deep inspiration, although its role is not as significant as the costodiaphragmatic recess, which has a greater volume. The lung expands into the costomediastinal recess even during shallow inspiration. The costomediastinal recess is most obvious in the cardiac notch of the left lung.
A punch is a tool used to indent or create a hole through a hard surface. They usually consist of a hard metal rod with a narrow tip at one end and a broad flat "butt" at the other. When used, the narrower end is pointed against a target surface and the broad end is then struck with a hammer or mallet, causing the blunt force of the blow to be transmitted down the rod body and focused more sharply onto a small area. Typically, woodworkers use a ball-peen hammer to strike a punch.
The Northern Tasmanian Football Association is an Australian rules football competition in northern Tasmania. This league is not related to the older version of the NTFA, which merged in 1987 with the NWFU to form the Northern Tasmanian Football League.
The elbow is the region between the arm and the forearm that surrounds the elbow joint. The elbow includes prominent landmarks such as the olecranon, the cubital fossa, and the lateral and the medial epicondyles of the humerus. The elbow joint is a hinge joint between the arm and the forearm; more specifically between the humerus in the upper arm and the radius and ulna in the forearm which allows the forearm and hand to be moved towards and away from the body. The term elbow is specifically used for humans and other primates, and in other vertebrates forelimb plus joint is used.
All Saints Church is a redundant Anglican church in the village of Little Wenham, Suffolk, England. It is recorded in the National Heritage List for England as a designated Grade I listed building, and is under the care of the Churches Conservation Trust. It stands in an isolated position close to Little Wenham Hall, about 0.6 miles (1 km) to the northwest of Capel St. Mary.
Jinbeisaurus is a genus of tyrannosauroid dinosaur from the Upper Cretaceous Huiquanpu Formation from Shanxi Province in China. The type and only species is Jinbeisaurus wangi. It is the first non-avian theropod known from Shanxi. Analysis of the specimen indicates that Jinbeisaurus is more derived than related tyrannosauroids such as Xiongguanlong and phylogenetically more advanced than Suskityrannus, to which it has been compared.
