This document discusses various internet information sources. It divides information sources into documentary and non-documentary sources, with the former including primary, secondary, and tertiary sources. Major internet information sources discussed include search engines, e-aggregators, subject gateways, mailing lists, directories, databases, e-tutorials, electronic theses and dissertations (ETDs), e-books, and software available online. Specific examples of search engines, e-aggregators, subject gateways, directories, and mailing lists are provided.
The document discusses the changing role of librarians due to new information technologies. It lists some modern information sources like blogs, wikis, and social networking sites that librarians can now use. Librarians can take on roles like being a technology specialist, promoting information use, managing institutional repositories, and acting as a community manager by making profiles and groups on social networking sites. New technologies allow librarians to collaborate with users and peers in real time and spread ideas virally.

This document provides guidelines and procedures for laboratory safety at Del Mar College. It discusses emergency contact information, equipment, and procedures. The key points are:
- In the event of an emergency, contact DMC Security Office at 361-698-1199, who will provide on-site assistance and ensure emergency services are notified.
- Laboratories are equipped with emergency showers, eyewash stations, first aid kits, fire blankets, and fire extinguishers to handle medical or hazardous materials emergencies.
- In the event of a fire, evacuate the building, pull the fire alarm, and only use a fire extinguisher if trained and the fire is small. Know the evacuation route and
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
This document provides guidelines and safety procedures for field trips. It discusses preparing for field trips by researching the location, filling out paperwork, and informing instructors of medical conditions. During field trips, students should stay with the group, bring necessary supplies like water and snacks, and follow guidelines for outdoor hazards like weather, plants, insects, and animals. Proper clothing is emphasized for differing weather conditions. Emergency contact information is provided.

This document outlines safety procedures and guidelines for laboratory work at Del Mar College's Department of Natural Sciences. It provides instructions for students to study the safety modules, take an accompanying quiz to score 100%, and lists emergency contact information. The document then details 5 modules that cover general rules, chemical safety, biohazards, emergency equipment, and field trip safety. Module 1 specifically addresses general laboratory safety procedures such as required personal protective equipment, waste disposal, housekeeping, and actions to take before leaving the laboratory each session.
This document outlines safety procedures and guidelines for a pre-lab course at Del Mar College. Module 3 discusses biohazard safety, including defining biohazards as bacteria, fungi, viruses, parasites, and bodily fluids. It notes that bloodborne pathogens are microorganisms that may be transmitted through blood or other bodily fluids and tissues, and can cause diseases like hepatitis and HIV. The module instructs students to always exercise universal precautions by treating all blood and fluids as potentially infectious, and to avoid touching their faces with gloves. It provides guidelines for proper biohazard disposal, including using sharps containers, biohazard waste containers, and separating solid and liquid dissection waste.
This document provides guidelines and safety procedures for field trips taken as part of a natural sciences laboratory course at Del Mar College. It outlines potential hazards in both upland and water environments of South Texas and recommends precautions to take. These include drinking plenty of water, applying sunscreen, avoiding poisonous plants and snakes, recognizing symptoms of heat illness, and having appropriate clothing and supplies for different weather conditions. Students must review this information and score 100% on the accompanying quiz before being allowed to participate in field trips.
This document provides safety guidelines and procedures for working in a chemistry laboratory at Del Mar College. It covers general rules like wearing personal protective equipment like splash-resistant goggles and covered clothing. It also discusses specific chemical hazards like toxins, reactivities, and routes of exposure. Labels on containers and equipment are explained to convey hazard information. Proper handling, storage, and disposal of chemicals is outlined. Completing a quiz on this material is required to remain registered for the class.
The Polymerase Chain Reaction (PCR) is a technique used to amplify small segments of DNA across many orders of magnitude. It was discovered in the 1980s by Kary Mullis and has since become one of the most important scientific advances in molecular biology. PCR allows for fast and inexpensive copying of DNA segments and is used widely in applications like disease detection, DNA fingerprinting, and diagnostics.
