ASP pasou by CATR iterations maiores, ASP 1.0 (distributed with IIS 3.0), ASP 2.0 (distributed with IIS 4.0), ASP 3.0 (distributed with IIS 5.0) and ASP.NET (part gives platform. NET Microsoft). As pre-.NET versions denomínanse now (since 2002) as classic ASP.
Not last classic ASP, ASP 3.0, hai obxectos integrated dispoñibles for six or programmer, Application, ASPError, Request, Response, Server and Session. Every ten obxecto a group of frequently used features and useful for creating dynamic web páxinas.
As páxinas poden be XER mesturando code scripts or do server side (including access to database) HTML. For example:
<% then if x = 1%>
<b> X equals one </ b>
<% else%>
<b> a different X </ b>
<% end if%>
This code results in html
<b> X equals one </ b>
cando establishing a variable or do server side to X = 1.
Facilitators to programming through various websites obxectos integrated, for example obxecto a cookie-based session, which hold as mentres variable is passed from páxina to páxina.
Since 2002, or classic ASP is being substituted for ASP.NET, which, among others cousas, substituting as linguaxes interpreted as VBScript or JScript linguaxes compiled by intermediate code (MSIL chamado or Microsoft Intermediate Language) as Visual Basic, C #, or calquera outro linguaxe that support platform. NET. Or MSIL code is compiled SINCE native code.
Acronym ASP (Amnesic do English Sellfish Poisoning) or to name two shellfish toxin amnésica brings together a group of biotoxins represented mainly navy polo domoico e os seus acid isomers. Polo agora lévanse identified nine isomers.
A toxin is produced by different species of diatoms do xeneraciones Pseudo-nitzschia. In Galicia coñécese since 1995, ea only species involved agora is tied to Pseudo-nitzschia australis.
Symptoms da poisoning
A molecular structure acid domoico Lembra do a do or glutamic acid glutamate, an amino acid neurotransmitter that acts not cerebral cortex and human receptors can join ós cerebrais for this amino acid not hippocampus ea amygdala, areas related cerebrais coa memory, acting as unha excitotoxina moi active.
A poisoning caused by ASP cadre different second dose inxerida ea sensitivity of each PERSO. In mild cases appear xa nas 24 hours primeiras gastrointestinais symptoms such as nausea, vomiting, diarrhea and abdominais ers. We noted serious cases can unha sintomatoloxía more nervous feature, with amnesia (loss gives memory), WEAKEN, confusion, sleepiness and Vertix. Os neurolóxicos poden be permanent damage and, in occasions, poisoning can be fatal.
The first case of poisoning studied ASP dates from 1987, nun clasped in Canada for consumption mexillóns. Ainda que o acid domoico xa was coñecer nas non algae known to cause poisoning puidese not consumers.
A toxin can be detected, two ademais molluscs, crustaceans and fish.
Análise
Or a formal method for quantifying gives toxin ASP is a high performance liquid chromatography (CLA ou, English form, HPLC).
A vixente regulation (EC No 853/2004 Regulamento pole laid down specific rules of hixiene two orixe animal foods) fixed a ceiling of 20 micrograms domoico acid per gram of meat (or mollusk body enteiro do calquera part cosumible separately) .
Control
A single control measure against a poisoning is to biotoxins vixilancia evolution gives two dinoflaxelados na auga sea and as mostraxes regular sized mollusk production different areas. Cando destes controis the results indicate that you níveis toxin you reach limits considered safe, dictate to ban extraction of mollusks that binds successive controis analytical demonstration or decline gives us shellfish toxin and guarantees to súa or aptitude for consumption.
Estes analytical controis are made, so official, Pol Consellerías Fisheries and Maritime Affairs and more pollen from Sanidade. Simultaneously, we establecementos marketing os mollusks (purification centers, or cocedoiros canneries), tamén be made within the seus own controis dos seus self-check programs (HACCP) as they are responsible da seguridade produits poñen not that market.
Curiosities
It appears that poisoning was unha consumption of contaminated anchovies or provocou a case of attack by xente centos bird happened in August 1961 in Santa Cruz, California, which is not feito inspirou for a súa Alfred Hitchcock movie ” Birds “(1963) [1].
Other sources claim that a film this basis nunha novel gives British writer Daphne du Maurier (1907-1989).
