Emergency Workers (Obstruction) Act 2006
The Emergency Services (Obstruction) Act 2006 (c 39) is an Act of the Parliament of the United Kingdom. It is intended to reduce the instances of obstruction of, or assaults on, emergency service personnel. Sections 1 to 6 came into force on 20 February 2007. The corresponding Swedish law is called ' (''blĂĄljussabotage'' for short, literally ''bluelight sabotage'' in English). Scope The Act defines emergency service personnel to cover firefighters, paramedic A paramedic is a healthcare professional trained in the medical model, whose main role has historically been to respond to emergency calls for medical help outside of a hospital. Paramedics work as part of the emergency medical services (EMS), ...s or other persons responding on behalf of the statutory ambulance service, members of HM Coastguard, and crew of a vessel of the RNLI or any other lifeboat. Offences and penalties The Act makes it an offence to obstruct any emergency service crew while responding to an ...

Obstructing The Field
Obstructing the field is one of the ten methods of dismissing a batsman in the sport of cricket. Either batsman can be given out if he wilfully attempts to obstruct or distract the fielding side by word or action. It is Law 37 of the Laws of cricket, and is a rare way for a batsman to be dismissed; in the history of cricket, there has been only two instances in Test matches, nine in One Day International (ODI) matches, and six in Twenty20 International matches. There have also been seven instances in Test cricket, and two in ODIs, where a batsman has been dismissed handled the ball, a mode of dismissal now folded into obstructing the field. One modern pattern of obstruction in limited overs cricket occurs when a batsman thinks that he is going to be run out and blocks the ball with his bat, or changes his course while running between wickets to block the ball. The obstruction has to be deliberate. Definition Obstructing the field is Law 37 in the Laws of cricket estab ...

Obstruction (baseball)
In baseball, obstruction is when a fielder illegally hinders a baserunner running within the basepath. Baserunners are generally permitted to run from base to base without being physically blocked or hindered by a fielder. The only time that a fielder is not obligated to "get out of the way" of a baserunner is when the fielder is fielding a hit ball or in possession of the ball. Definition Official Baseball Rule 2.00 defines obstruction as: The comment to Rule 7.09(j) adds that High school and college versions of the rule also add rules against malicious or flagrant contact. Types of obstruction and corresponding penalties Any case of obstruction falls into one of two categories (formerly called type "A" and type "B" until the 2014 rewriting of the MLB Umpire rulebook), after the subsection of Rule 6.01(h), in which each type of obstruction, and the corresponding penalties, are described. (1) (2) In addition, the fielder who commits the obstruction is charged with an ...

Propagation Path Obstruction
In telecommunications, a propagation path obstruction is a man-made or natural physical feature that lies near enough to a radio path to cause a measurable effect on path loss, exclusive of reflection effects. An obstruction may lie to the side, above, or below the path. Ridges, bridges, cliffs, buildings, and trees are examples of obstructions. If the clearance from the nearest anticipated path position, over the expected range of Earth radius ''k''-factor, exceeds 0.6 of the first Fresnel zone A Fresnel zone ( ), named after physicist Augustin-Jean Fresnel, is one of a series of confocal prolate ellipsoidal regions of space between and around a transmitter and a receiver. The size of the calculated Fresnel zone at any particular di ... radius, the feature is not normally considered an obstruction. References * Radio frequency propagation {{radio-stub ...

Graph Theory
In mathematics and computer science, graph theory is the study of ''graph (discrete mathematics), graphs'', which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of ''Vertex (graph theory), vertices'' (also called ''nodes'' or ''points'') which are connected by ''Glossary of graph theory terms#edge, edges'' (also called ''arcs'', ''links'' or ''lines''). A distinction is made between undirected graphs, where edges link two vertices symmetrically, and directed graphs, where edges link two vertices asymmetrically. Graphs are one of the principal objects of study in discrete mathematics. Definitions Definitions in graph theory vary. The following are some of the more basic ways of defining graphs and related mathematical structures. Graph In one restricted but very common sense of the term, a graph is an ordered pair G=(V,E) comprising: * V, a Set (mathematics), set of vertices (also called nodes or points); * ...

Graph Minor
In graph theory, an undirected graph is called a minor of the graph if can be formed from by deleting edges, vertices and by contracting edges. The theory of graph minors began with Wagner's theorem that a graph is planar if and only if its minors include neither the complete graph nor the complete bipartite graph ., p. 77; . The Robertson–Seymour theorem implies that an analogous forbidden minor characterization exists for every property of graphs that is preserved by deletions and edge contractions., theorem 4, p. 78; . For every fixed graph , it is possible to test whether is a minor of an input graph in polynomial time; together with the forbidden minor characterization this implies that every graph property preserved by deletions and contractions may be recognized in polynomial time. Other results and conjectures involving graph minors include the graph structure theorem, according to which the graphs that do not have as a minor may be formed by ...

Forbidden Graph Characterization
In graph theory, a branch of mathematics, many important families of Graph (discrete mathematics), graphs can be described by a finite set of individual graphs that do not belong to the family and further exclude all graphs from the family which contain any of these forbidden graphs as (induced) Glossary_of_graph_theory#subgraph, subgraph or Graph minor, minor. A prototypical example of this phenomenon is Kuratowski's theorem, which states that a graph is planar graph, planar (can be drawn without crossings in the plane) if and only if it does not contain either of two forbidden graphs, the complete graph and the complete bipartite graph . For Kuratowski's theorem, the notion of containment is that of graph homeomorphism, in which a subdivision of one graph appears as a subgraph of the other. Thus, every graph either has a planar drawing (in which case it belongs to the family of planar graphs) or it has a subdivision of at least one of these two graphs as a subgraph (in which ...

Obstructionism
Obstructionism is the practice of deliberately delaying, preventing or Abuse of process, abusing a process. In politics Obstructionism or policy of obstruction denotes the deliberate interference with the progress of a legislation by various means such as the filibuster which consists of extending the debate upon a proposal in order to delay or completely prevent a vote on its passage. Another form of parliamentary obstruction practiced in the United States and other countries is called "slow walking". It specifically refers to the extremely slow speed with which legislators walk to the podium to cast their ballots. For example, in Japan this tactic is known as a "cow walk", and in Hawaii it is known as a "Devil's Gambit". Consequently, slow walking is also used as a synonym for obstructionism itself. Obstructionism can also take the form of widespread agreement to oppose policies from the other side of a political debate or dispute. Notable obstructionists John O'Connor Po ...
