United Nations Security Council Resolution 2720, adopted on 22 December 2023, called for increased aid for the 2023 Gaza humanitarian crisis, including the provisioning of fuel, food, and medical supplies. It also explicitly demanded the opening of all Gaza border crossings to humanitarian aid, including the Kerem Shalom border crossing, [ 1 ...
An adjustable pressure-limiting valve (commonly abbreviated to APL valve, and also referred to as an expiratory valve, relief valve or spill valve) is a type of flow control valve used in anaesthesiology as part of a breathing system. It allows excess fresh gas flow and exhaled gases to leave the system while preventing ambient air from ...
The first Skyline was introduced on 24 April 1957, at the Takarazuka Theater, in Hibiya, Tokyo, [3] for Fuji Precision Industries, marketed as a luxury car.It featured a 1.5 L (1,482 cc) GA-30 engine (also known as FG4A-30) producing 44 kW (60 hp) at 4,400 rpm, which was previously used in the prototype Subaru 1500, Subaru's first car.

A relief valve DN25 on cooling water pipe from heat exchanger Schematic diagram of a conventional spring-loaded pressure relief valve. A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire.
Mass flow controller. A mass flow controller ( MFC) is a device used to measure and control the flow of liquids and gases. [ 1] A mass flow controller is designed and calibrated to control a specific type of liquid or gas at a particular range of flow rates. The MFC can be given a setpoint from 0 to 100% of its full scale range but is typically ...
Camless piston engine. A camless or free-valve piston engine is an engine that has poppet valves operated by means of electromagnetic, hydraulic, or pneumatic [1] actuators instead of conventional cams. Actuators can be used to both open and close valves, or to open valves closed by springs or other means. Camshafts normally have one lobe per ...
Control valve. A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [ 1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. In automatic control terminology, a control ...
