So what is a hydraulic cylinder? The simple answer is a sealed cylinder, or a circular prism, that is fully filled with some type of liquid, normally an oil, with two openings for two pistons. Continue reading “How Do Cranes Work? Part III – The Science Behind the Construction”

Mysterious, Moving, Magnetic North Pole – Cause – Consequence – Florida Airport Runway Closure!

Slowly but steadily, planet Earth’s northern magnetic pole seems to be drifting towards Russia – the recent consequences of which has been the impacting of commercial flights above Florida, forcing closure of air-field runways at Tampa.

Earth’s magnetic fields change relatively slowly, explains the FAA, being marked out at 10 degree increments. The magnetic field has swung from approximately 10 degrees east 300 years ago, to 25 degrees west in the early 19th century. It is now swinging back, presently at 3 degrees west.

Tampa International Airport was forced to readjust its runways in early January, 2011, because of the magnetic field movement, closing its primary runway for a week to change taxiway signs.

Types of Inheritance in Medical Genetics II – X-Linked Recessive and Dominant Inheritance

From the first part of this article, inheritance in Medical genetics can be divided into four kinds. Autosomal Recessive and Dominant types and X-linked recessive and Dominant types. The Autosomal types, both the recessive and dominant have been discussed in previous articles. Now let’s talk about the X-linked or rather sex-related type of inheritance.

X-linked recessive inheritance
1. There is ‘oblique’ transmission, i.e, in the pedigree, a line drawn through the affected persons is oblique.
