Experience the Museum's Whale Wash
Each year, the Museum's blue whale model gets spruced up in an annual scrub down. The 2014 Whale Wash was shared widely on social media when the Museum broadcast a special livestream of the event. Now viewers can re-live the famous whale's spa day with this recorded video. In the Milstein Hall of Ocean Life, visitors at the Museum watched as members of the Exhibition department use long-handled brushes and vacuums to wipe away the dust from the 94-foot long, 21,000-pound model.

4.2 Arresting protein synthesis The regulation of T
b in hibernators has traditionally been viewed as the fundamental physiological process in hibernation. But recently, questions have been raised about whether thermal changes initiate or simply accompany metabolic depression. Is the metabolic inactivity of animal tissues during bouts of torpor or in hibernation, the cause or the result of hypothermia? A common-sense view is that temperature directly influences metabolism by regulating enzyme activity. Evi

Multidisciplinary System Design Optimization, Spring 2004
This course is mainly focused on the quantitative aspects of design and presents a unifying framework called "Multidisciplinary System Design Optimization" (MSDO). The objective of the course is to present tools and methodologies for performing system optimization in a multidisciplinary design context, focusing on three aspects of the problem: (i) The multidisciplinary character of engineering systems, (ii) design of these complex systems, and (iii) tools for optimization.
24.900 Introduction to Linguistics (MIT)
This core-curriculum linguistics class will provide some answers to basic questions about the nature of human language. Topics include the intricate system that governs language, how it is acquired, the similarities and differences among languages, and how spoken (and signed) language relates to written language, among others.
Mini project : ROM based sine wave generator : presentation transcript
This is a Mini Project presentation introducing a ROM-Based Sine Wave Generator. It is part of the 2009/10 BEng in Digital Systems and Computer Engineering (course number 2ELE0065) from the University of Hertfordshire. All the mini projects are designed as level two modules of the undergraduate programmes. This project requires the establishment of a communication protocol between two 68000-based microcomputer systems. Using ‘C’, students will write software to control all aspects of comp
South African Child Gauge 2009/2010
The South African Child Gauge is produced annually by the Children Institute University of Cape Town to monitor government and civil society progress towards realising the rights of children This issue focuses on child health. The South African Child Gauge is divided into three parts: PART ONE Children and law reform. Part one discusses recent legislative developments affecting child health In this issue there is commentary on the Children's Act the Prevention of and Treatment for Substance Abus
The Kepler Mission: Searching for Other Earths in the Cosmos
Dr Fanson speaks about the Kepler project, NASA's first mission capable of discovering Earth-size planets orbiting other stars in our galaxy. Scheduled for launch in early 2009, Kepler seeks to answer an age-old question: Are there other habitable worlds in the cosmos? The centuries-old quest for other worlds like our Earth has been rejuvenated by the intense excitement and popular interest surrounding the discovery of giant planets like Jupiter orbiting stars beyond our solar system. With the e
Study Abroad 2010: INDIA
Students followed the Ganga (Ganges) River system from the Himalayas down to Calcutta and beyond as they took part in two upper level Geology courses: 1. "Water Resources of India" focuses on the efforts of government to stimulate economic growth while protecting the environment and cultural resources of the river system. The course covers basic water resources and hydrology principles and then delves into issues specific to India. 2. "Pollution in the Developing World" focuses on the fundame

E-science, E-research and E-learning:
New Perspectives for Graduate Studies
The quality of education for doctoral students is closely linked to the quality of the research they undertake. Benefiting from technological advances, new distributed and collaborative research practices can be witnessed. The concept of e-science has emerged and evolved to the concept of e-research. These concepts bring about a new research philosophy and the notion of collaboratory. Our research project aims to develop a renewed doctoral training approach and to facilitate researchers' adoptio
Web-based teaching as a performance enhancer in foreign language teaching in Sri Lanka
This paper discusses the results of a pilot study conducted at University of Kelaniya in integrating web-based teaching into the study programmes of German as a Foreign Language. Since German is not a language popular at secondary school level, student offering to read the language at the university commence language learning as beginners. Albeit the courses are designed to impart language knowledge to all students equally, the performance of the majority of students at examinations indicated th
Teaching the Digital Natives: Austrian Best Practice Projects
The following three projects promote e-Learning in Austrian schools and stimulate the change to student centred and collaborative learning and teaching. These projects bring teachers closer to learning habits of the digital natives and prepare our students for live long learning.

Made up true story
Sam Winston, who also wrote/illustrated this work presents some ideas on the project he has been working on for the last three years. Winston’s experiments came from looking at the structures of different types of literature: from storybooks to bus timetables: “The way you navigate a timetable is very different to the way you read a short story” he comments. “I wanted to take these different types of visual navigation and introduce them to each other: a timetable re-ordering all the w
Office XP for Business
Manual to support students in using the Microsoft Office XP operating system and the Microsoft Office 2003 software suite. In many developing countries IS textbooks tend to be expensive despite the best and, I believe, sincere efforts of educational publishers to keep their developing country rates as low as humanly possible. This book (except for the Access section) has been released under the Creative Commons license, i.e. it is freely available for (educational) use to anyone who wants it.
