Science Bulletins: 125,000 Gorillas Discovered in Congo
A survey of 47,000 square kilometers of forest and swampland in northern Congo has revealed a previously unknown population of endangered western lowland gorillas. The estimated tally of 125,000 gorillas in this region doubles previous counts of this subspecies of gorilla. The results of the survey, which was led by teams from the Wildlife Conservation Society and the government of the Republic of Congo, may propel the establishment of a new protected area in the region.
The Chi-Square Distribution: Test for Homogeneity
The Test for Homogeneity is used to make a conclusion about whether two populations have the same distribution. To calculate the test statistic for a test for homogeneity, follow the same […]
Science in Focus: Energy: Workshop 3. Transfer and Conversion of Energy
Change happens when energy is transferred or converted. In this session, examine conversion between potential and kinetic energy. Through examples, see how events that involve a small amount of energy can trigger much larger events.,This segment explores the question "What happens when energy is converted from one form to another?" by visiting classrooms as well as interviewing students and scientists.
Matisse, Luxe, Calme et Volupté, 1904 - Smart History at Khan Academy

EAHA Day 3 Session 1: Fire Lecture
Universities in the Eastern Africa Region have come together to implement an initiative Health Emergency Management Program (HEMP) that will build the capacity of local governments in the region to manage and plan for response to major disasters of public health importance. The Eastern African Region is prone to many natural and technological disasters of different kinds. There is not one nation in the region that is not vulnerable to the devastating effects of these disasters. Many of these dis
Glass transition: energy dissipation as rubber ball bounces at 25 °C
Part of a series of videos showing the glass transition in polymers, and the resulting change in energy dissipation on impact: Video at one tenth actual speed of a rubber ball bouncing at 25° C (well above Tg), showing that the ball loses little energy as it bounces.

Procedures in Obstetrics & Gynaecology
Obstetrics and gynaecology is a practical subject. In order to be a competent practitioner, the trainee needs to acquire a broad range of skills. Learning the art and science of surgery and medicine has not changed over the centuries and most procedures are learnt by patient mentoring by senior colleagues. The purpose of this book is to provide the trainee with a step by step practical approach to a number of everyday procedures in Obstetrics and Gynaecology.The trainee will be able to use the t
