In diesem Video schauen wir uns erstmal die verschiedenen Datentypen in PHP an. Danach rechnen wir ein wenig mit PHP.

In dieser Folge schauen wir uns einen weiteren Bestandteil von PHP an: Arrays.

In dieser Folge verarbeiten wir Formulardaten und sehen uns die sogenannten $_GET und $_POST Variablen an.

An essential and practical text for both students and teachers of AC electrical circuit analysis, this text picks up where the companion DC electric circuit analysis text leaves off. Beginning with basic sinusoidal functions, ten chapters cover topics including series, parallel, and series-parallel RLC circuits. Numerous theorems and analysis techniques are examined including superposition, Thévenin's theorem, nodal and mesh analysis, maximum power transfer and more. Other important topics include AC power, resonance, Bode plots and an introduction to three-phase systems. Each chapter begins with a set of chapter objectives and includes a summary and review questions. A total of over 500 end-of-chapter exercises are included. A companion laboratory manual is available.

The coral reefs of the South Pacific island nation of Vanuatu are the backbone of the island's environmental and economic health. Today they face destruction from a silent predator that can rapidly decimate an entire reef. In this video, students learn about how a starfish is destroying the coral reefs of Vanuatu and how the islanders are adapting.

This video begins in the lush deltas of Bangladesh. The host of the video learns how communities are adapting to changing monsoons and dangerous sea-level rise. Floating gardens and floating schools are just the start of some of the country's innovative strategies.

In this video, learn how communities in the arid high-mountain region of Ladakh rely on glacial water to feed streams and water crops during the spring and summer months. Global warming is dramatically reshaping the future of these areas. Meet a Ladakhi teacher and engineer who devised a method to capture and store glacial runoff into magnificent ice pyramids that are used as water resources throughout the summer and during peak agricultural months.

In this video, an entrepreneur is finding new ways to manage the invasive Asian carp problem in the Mississippi and Ohio rivers. Once introduced to help mitigate an algae problem, the carp became invasive. This video highlights how the local community has adapted to the issue, including how they have gained ideas about how to utilize the carp from other cultures to help mitigate the issue.

A video from the Extreme Ice Survey in which Dr. Tad Pfeffer and photographer Jim Balog discuss the dynamics of the Columbia glacier's retreat in recent years through this time-lapse movie. Key point: glacier size is being reduced not just by glacial melting but due to a shift in glacial dynamics brought on by climate change.

This book was created to support Project 677 in APSC 100 in the Faculty of Engineering at Queen’s University during the winter term of 2019, and is being updated and expanded to support Project 725 in Winter 2021. It provides a publicly visible collection of information that will help with this design project. Use of these resources elsewhere under the CC license is encouraged, but not supported. The contents of this book will grow and change over the term. Please fell free to add your comments or questions in any of the sections and I will try to address them.

The resources in this book are not comprehensive and are only intended to provide a starting point to explore design options. In particular, there will be many examples illustrated by single products that are not the only, or even the best solutions for a particular application. You will need to go well beyond the contents of this book to make your independent design decisions.

The models used for building heat transfer are very much simplified for an introduction to the ideas and should be used cautiously. Design of actual building systems should be undertaken in much greater detail. The target here is to use models that don’t require you to learn any new physics.

The secondary reason this book exists is to give me some practice using PressBooks to develop Open Educational Resources (OER). Some of the files that are linked from this book are on Google Drive, and some are on GitHub.

CropWatch is a central resource for University of Nebraska–Lincoln Extension information on crop production and pest management. It is written by Extension Educators and Specialists and produced by IANR Media in the UNL Institute of Agriculture and Natural Resources.

Information is organized into two key areas, each of which offers thousands of crop-specific articles for Nebraska producers and crop consultants:

The CropWatch newsletter, which includes timely articles published to the site's home page. New issues are published weekly during the heart of the crop production season and generally biweekly during the remainder of the year. Older articles are archived for later review.

CropWatch also includes:

- Calendar of ag events and programs
- Daily news and updates via Twitter at UNL_CropWatch (also displayed on the home page)
- Ag decision-aid tools and resources from UNL Extension
- Content tags at the end of individual stories to help you located related articles released since April 2016.
- Use the Search box in the top right of every page or the Archives to locate additional articles.
- Crop-specific production and pest management sections, with additional sites for whole farm and production systems. Use the top red-bar navigation to access specific crop, management and related topics.

In this 6-part activity, students learn about climate change during the Cenozoic and the abrupt changes at the Cretaceous/Paleogene boundary (65.5 million years ago), the Eocene/Oligocene boundary (33.9 million years ago), and the Paleocene/Eocene boundary (55.8 million years ago).

In this activity, students use the absorption spectra of greenhouse gases to explore the nature of the greenhouse effect.

A Library guide to success at university

Short Description:
There is so much to learn when you start university. This book will focus on the most important academic skills you'll need to get started, leaving sufficient 'room' for actual learning and reducing your cognitive load. This book aims to give you a quick understanding of these skills which you can then apply within your area of study. This book aligns to UN Sustainable Development Goal 4 – Quality Education supporting inclusive and affordable access to higher educational resources.

This video follows biologist Gretchen Hofmann as she studies the effects of ocean acidification on sea urchin larvae.

Acoustics (from Greek ακουστικός pronounced akoustikos meaning "of or for hearing, ready to hear") is the science that studies sound, in particular its production, transmission, and effects. The science of acoustics has many applications which are dependent upon the nature of the sound that is to be produced, transmitted or controlled.
