El documento explica qué es el wifi, los tipos de comunicación wifi (802.11b y 802.11g), cómo se utiliza el wifi en el hogar mediante un enrutador conectado al módem y dispositivos wifi, y cómo los enrutadores controlan el acceso a la información transmitida por la red wifi. También contrasta el uso del wifi en el hogar frente al de las empresas.
BIOREMEDIATION OF HAZARDOUS POLLUTANTS USING FUNGIijcoa
Use of chemicals in industrial processes, agricultural practices, nuclear experiments and various areas of our daily lives result in the release of potential toxic chemicals into the environment either on purpose or by accident. Chemicals that are known to pollute the environment include heavy metals, drugs, hydrocarbons, halogenated solvents, endocrine disrupting agents and agricultural chemicals. After their release, these pollutants are transported through the soil, atmosphere and water sources polluting them, thus posing a serious problem for survival of mankind. In the past, traditional method of disposing hazardous pollutants was by digging a hole and filling it with waste material but this method of waste disposal was difficult to continue due to lack of new places to dump. Many physical and chemical based technologies for waste disposal like high-temperature incineration and chemical decomposition methods have evolved in the years. Though these techniques were very effective at reducing a wide range of contaminants, at the same time they had several drawbacks like being complex in nature, uneconomical, and were not easily accepted by the public. Thus focus was shifted towards using modern day bioremediation process as a suitable alternative. Bioremediation is a microorganism mediated transformation or degradation of contaminants into nonhazardous or less-hazardous substances. In this process the contaminant or pollutant is used as a nutrient or energy source by the microorganism and the enzymes secreted by the microorganisms attack the pollutants and convert them to less hazardous products. Among the various microorganisms, fungi possess the biochemical and ecological capacity to degrade environmental organic chemicals either by chemical modification or by influencing chemical bioavailability. Ability of fungi to form extended mycelial networks, the low specificity of their enzymes and their ability of using pollutants as a growth substrate make fungi well suited for bioremediation processes. In contrast to bacteria, fungi are able to extend the location of their biomass through hyphal growth in search of growth substrates. A bioremediation process to be effective, manipulation of environmental parameters to allow microbial growth and degradation to proceed at a faster rate are required. By integrating proper utilization of natural or modified fungal capabilities with appropriate engineering designs to provide suitable growth environment, bioremediation using fungi can be successful in treating hazardous pollutants.

Secrets of building a company website that drives sales [Webinar]Jonathan Foster
In this presentation we covered several ways to optimize your company website for conversions. We also discussed how to make sure your page draws people in and encourages them to stay on your site. Additionally, we went over a quick template of how to create awesome company blog content and how to immediately increase website traffic with a super simple 5 step process.
1. - En que consiste / la tecnologia wifi
Cuales son los tipos de comunicación wifi que se
necesita para la comunicación wifi - como se usa wifi
en el hogar - que es un enrutador-´como se utiliza el
wifi en el hogar y las empresas.
2. QUE ES WIFI?
Wireless Fidelity. Tecnología de acceso inalámbrico
basada en la familia de estándares 802.11 del IEEE.
Las velocidades de acceso pueden llegar hasta 11
Mbps ó 54 Mbps, dependiendo del estándar, y el
alcance máximo es de algunos centenares de
metros. El punto de acceso estará conectado a una
red de datos (como Internet) mediante otra solución
de acceso (satélite, ADSL, cable, LMDS...) que
proporcionará la conexión a la red de datos que
compartirán los usuarios.

para la comunicación wifi

En la actualidad podemos encontrarnos con dos tipos de
comunicación WIFI:
802.11b, que emite a 11 Mb/seg, y
802.11g, más rapida, a 54 MB/seg.
De hecho, son su velocidad y alcance (unos 100-150 metros
en hardaware asequible) lo convierten en una fórmula perfecta
para el acceso a internet sin cables.
4. Como se utiliza wifi en la casa.
Para tener una red inalámbrica en casa sólo necesitaremos
un punto de acceso, que se conectaría al módem, y un
dispositivo WIFI que se conectaría en nuestro aparato.
Existen terminales WIFI que se conectan al PC por
USB, pero son las tarjetas PCI (que se insertan
directamente en la placa base) las recomendables, nos
permite ahorrar espacio físico de trabajo y mayor rapidez.
Para portátiles podemos encontrar tarjetas PCMI
externas, aunque muchos de los aparatos ya se venden
con tarjeta integrada. En cualquiera de los casos es
aconsejable mantener el punto de acceso en un lugar alto
para que la recepción/emisión sea más fluida. Incluso si
encontramos que nuestra velocidad no es tan alta como
debería, quizás sea debido a que los dispositivos no se
encuentren adecuadamente situados o puedan existir
barreras entre ellos (como paredes, metal o puertas).
5. Q son enrutadores?
El funcionamiento de la red es
bastante sencillo, normalmente sólo
tendrás que conectar los dispositivos e
instalar su software. Muchos de los
enrutadores WIFI (routers WIFI)
incorporan herramientas de
configuración para controlar el acceso
a la información que se transmite por
el aire.
6. El wifi del hogar es diferente al de la
empresa por que el de la casa es por
que tiene redes diferentes varias
comunicaciones fáciles y el de la empresa
es por que se facilita mas rápido por el
lugar y los aparatos electrónicos son mas
rápidos para navegar wifi.
