Countermeasure (law)
Countermeasure in public international law refers to reprisals not involving the use of force. In other words, it refers to non-violent acts which are illegal in themselves, but become legal when executed by one state in response to the commission of an earlier illegal act by another state towards the former. Definition The leading case on countermeasure is the 1997 International Court of Justice decision in Gabčíkovo – Nagymaros Dams case. The court remarked that, for a countermeasure to be justifiable, it must meet the conditions below: # The act constituting countermeasure must be taken in response to a previous intentional wrongful act of another state and must be directed against that state. # The injured state must have already called upon the state committing the wrongful act to discontinue its wrongful conduct or to make reparation, but the request was refused. # The countermeasure must be commensurate with the injury suffered, taking into account the rights in questio ...

Ávila 24-8-2002
Ávila (, , ) is a city of Spain located in the autonomous community of Castile and León. It is the capital and most populated municipality of the Province of Ávila. It lies on the right bank of the Adaja river. Located more than 1,130 m above sea level, the city is the highest provincial capital in Spain. Distinctly known by its medieval walls, Ávila is sometimes called the ''Town of Stones and Saints'', and it claims that it is one of the towns with the highest number of Romanesque and Gothic churches per capita in Spain. It has complete and prominent medieval town walls, built in the Romanesque style; writer José Martínez Ruiz, in his book ''El alma castellana'' ("The Castilian Soul"), described it as "perhaps the most 16th-century town in Spain". The town is also known as ''Ávila de los Caballeros'', ''Ávila del Rey'' and ''Ávila de los Leales'' ("Ávila of the knights", "Ávila of the king", "Ávila of the loyal ones"), each of these epithets being present in the ...

Diplomatics
Diplomatics (in American English, and in most anglophone countries), or diplomatic (in British English), is a scholarly discipline centred on the critical analysis of documents: especially, historical documents. It focuses on the conventions, protocols and formulae that have been used by document creators, and uses these to increase understanding of the processes of document creation, of information transmission, and of the relationships between the facts which the documents purport to record and reality. The discipline originally evolved as a tool for studying and determining the authenticity of the official charters and diplomas issued by royal and papal chanceries. It was subsequently appreciated that many of the same underlying principles could be applied to other types of official document and legal instrument, to non-official documents such as private letters, and, most recently, to the metadata of electronic records. Diplomatics is one of the auxiliary sciences of hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Damage Control
In navies and the maritime industry, damage control is the emergency control of situations that may cause the sinking of a watercraft. Examples are: * rupture of a pipe or hull especially below the waterline and * damage from grounding (running aground) or hard berthing against a wharf. * temporary fixing of bomb or explosive damage. Measures used Simple measures may stop flooding, such as: * locking off the damaged area from other ship's compartments; * blocking the damaged area by wedging a box around a tear in the ship's hull, * putting a band of thin sheet steel around a tear in a pipe, bound on by clamps. More complicated measures may be needed if a repair must take the pressure of the ship moving through the water. For example: * Thermal lance cutting around the rupture. * Oxyacetylene welding or electric arc welding of plates over the rupture. * Quick-drying cement is applied underwater over the rupture. Damage control training is undertaken by most seafarers, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fortification
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they act ...

Jump Server
A jump server, jump host or jump box is a system on a network used to access and manage devices in a separate security zone. A jump server is a hardened and monitored device that spans two dissimilar security zones and provides a controlled means of access between them. The most common example is managing a host in a DMZ from trusted networks or computers. Background In the 1990s when co-location facilities became more common there was a need to provide access between dissimilar security zones. The jump server concept emerged to meet this need. The jump server would span the two networks and typically be used in conjunction with a proxy service such as SOCKS to provide access from an administrative desktop to the managed device. As SSH-based tunneling became common, jump servers became the de facto method of access. Implementation Jump servers are often placed between a secure zone and a DMZ to provide transparent management of devices on the DMZ once a management session has b ...
