Boxed In and Wrapped Up
Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package things. Students then consider why consumer goods generally aren't packaged in cube-shaped boxes, ev
Buck-Toothed Demon Lizard | How To Confuse A Mosquito
Dr. Hans Sues from the National Museum of Natural History discusses the new T. rex relation he recently identified. Also, learn how we might avoid mosquitoes by confusing their ability to hone in on us.
PediNeuroLogic Exam: Introduction: General Physical Examination
In the neurological assessment of the child don't neglect the general physical examination. Some of the parts of the general examination that are particularly important to note are the following: Somatic growth - measure height and weight and compare percentiles with head circumference; Search for dysmorphic features - carefully study the face especially the midface. There is the old adage that the face reflects the brain because anomalies of the midface are often associated with underlying brai
PediNeuroLogic Exam: Newborn: Abnormal: Tone - Scarf Sign
The scarf maneuver demonstrates low shoulder girdle tone. The hand actually can be pulled beyond the opposite shoulder and the elbow goes past the midline. A neuroscience tutorial focusing on those aspects of the pediatric neurological examination that are unique to the child's nervous system, with an emphasis on important neurodevelopmental milestones.
PediNeuroLogic Exam: Newborn: Abnormal: Reflexes - Deep Tendon Reflexes
Testing deep tendon reflexes on this baby demonstrates that they are present. This is important in trying to sort out if the baby has low tone from an upper motor neuron lesion or if he has a lower motor neuron or muscle disorder. In older children and adults, an upper motor lesion causes spasticity but in babies an upper motor neuron lesion can cause hypotonia. A disease of the lower motor neuron is unlikely with the deep tendon reflexes being present. The baby could still have a muscle disorde

VLSI Test Technology and Reliability
Course Description: With the continue scaling of transistor feature sizes, VLSI chip density continue increases. This results in a continue increase in the complexity VLSI technology where it has reached the point where billions of transistors are integrated on a single chip (like it is the case for System on Chip). To guarantee the satisfaction of the customers, the produced VLSI chips have to be reliable and fully tested. Verification testing and production testing represents 50 t0 60% of the
7.3 RFID technology
Are you a technophobe? Bluetooth, Ethernet WiFi – are they terms that mean nothing to you? This unit will gently guide you to an understanding of how devices 'talk' to each other and what technologies and processes are involved. You will also look at wired and wireless communication technologies, introducing you to some of the key methods involved.
Dark leafy seadragon face
This seadragon has a snout and you can see one of its eyes. The tube-shaped snout is what the seadragon uses to eat small bits of food with.

Neuropathology Navigator consists of Neuropathology self-instructional units designed for second-year medical students in a neuroscience systems course. The website can be used online, or can be downloaded for local use. The website has been designed to provide students with easy access and visibility to all topics; after clicking on a topic the sub-topics are listed for easy navigation. Learning goals are to provide a basic framework of neuropathology for second-year medical students with resou
Some of the most unusual and versatile of all the mammals are the groups that live, feed and reproduce underwater. In this unit we will see how these formerly land-based mammals adapted to a return to the water, discussing such challenges as breathing, movement and communication. This is the seventh unit in the ‘Studying mammals’ series.
From Ridiculous to Brilliant: Why We Play at Work
The American workplace might be better off if it borrowed some concepts from a typical kindergarten classroom, including bins with toys, and unstructured time with friends. Two partners from IDEO, a global power in design and branding, discuss the importance of play in their creative process, and offer techniques that other organization
