This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"For an anesthesiologist, medically induced transitions between conscious and unconscious brain states are just part of the daily routine. But precisely how general anesthetics produce a state of unconsciousness isn’t all that clear. That’s because researchers are missing a key piece to the puzzle: no one has been able to definitively pinpoint exactly where consciousness comes from. The prevailing idea is that there’s no single “seat” of consciousness – it’s more the product of multiple interactions occurring throughout the brain. A recent review article published in the journal Anesthesiology argues that, because of this global network property, the field of network science could provide the framework needed to more comprehensively understand the biological basis of consciousness…and by extension the principles underlying anesthetic-induced unconsciousness..."

The purpose of this lesson is for adult learners to improve their communication skills --- specifically reading, writing, speaking and listening --- by using the Scientific Method to solve a nursing problem. The target audience of this lesson is adults at the 12th grade reading and writing levels. This lesson is designed for a face-to-face, instructor-led classroom setting.

This kit is aimed at teachers and their pupils at the end of primary school education living in areas affected by or under threat from desertification.

When working on longer or more important writing projects, writers often face many of the same issues commonly discussed in connection with writer’s block: information, order, insight, and need. These, combined with the pressures we feel about now having to write texts that are not only longer but also higher stakes projects, often make projects seem overly intimidating. From the very beginning of your work on a thesis, article, dissertation, or book project, you must take steps to minimize the issues that would slow you down or prevent you from finishing.

A research article with information on the differences between rubrics, checklists, and rating scales. It includes helpful tips for quality rubric design.

"Over the past decade, a variety of new drugs and surgical techniques have been developed to lower intraocular pressure and treat glaucoma. This trend has reinvigorated interest in understanding how and where aqueous humour outflow occurs. Three main pathways are currently known: trabecular, or **_conventional_**, outflow; uveoscleral, or **_unconventional_**, outflow; and subconjunctival outflow. Current methods for imaging these pathways are at varying stages of development, with conventional outflow imaging being the most advanced. Nevertheless, each route possesses a unique biology that can be leveraged in the quest for more knowledge about aqueous humour outflow. Conventional outflow accounts for approximately 90% of aqueous humour flow under physiologic conditions. Here, imaging methods have focused on capturing structural or flow-based features. Optical coherence tomography has enabled researchers to assess ocular tissue in live human subjects..."

What started out as a gallery to display the calligraphy of two artists is today a website devoted to the art of Arabic calligraphy. It includes a wall where other artists can post their own Arabic calligraphy, basic information on the Arabic language, a blog about calligraphy, and more. Users can post comments on the website.

This dictionary (published in 1899) is intended for the use of students. Due to its publication date, it corresponds more to classical Arabic or older formal Arabic rather than to MSA. It is organized by root with derivative forms of words are included under their three-letter root.

This is a list of over 200 cognates in English and in Arabic separated into topical chapters, like food, animals, and politics. Words are written in English, Arabic, and in Arabic transliteration for the very beginner. It also includes a list of the letters in the Arabic alphabet and how they are pronounced. It is intended to show users how much Arabic they already know.
