Psychadelic Ink

It turns out that fluid dynamics can be pretty entertaining stuff once you forget how much calculus is involved (DISCLAIMER: My feelings about calculus are purely personal, as I’d rather go to the dentist). Mark Mawson’s photographs of ink in water demonstrate spooky clouds of complex mixing, and wisps of laminar flow.

Your fluid dynamics friends at F**kYeahFluidDynamics have links to facts about these physical phenomena. Also, some previous posts on the physics of ink on paper, and how ink’s natural patterns of flow can look just like neurons.

Salt Made From Tears combines centuries-old craft with the freshest human tears which are gently boiled, released into shallow crystallisation tanks, then harvested by hand and finally rinsed in brine.

“…O’Connell’s new sculptures and drawings explore microscopic imagery with particular reference to the use of the con focal microscope… Combining found materials such as coral and willow with synthetic materials, she recreates molecular forms on a massive scale, revealing the invisible architecture of our internal structures.”

Wolff-Parkinson-White Syndrome

This is a heart disorder occurring in approximately 0.1%-0.3% of the general population.

It is a type of pre-excitation syndrome, meaning that the ventricles depolarise (and therefore contract) prematurely.

Normally the atria and ventricles are isolated, with an electrical impulse only being able to spread from one to the other by the atrioventricular node which delays and reduces the strength of the initial impulse so ventricular contraction is regulated and does not occur too soon or too frequently.

Individuals with WPW however have an accessory pathway (as shown above) called the bundle of Kent which creates another electrical connection between the atria and ventricles, bypassing the atrioventricular node. The bundle of Kent does not delay nor reduce the strength of the initial impulse and may even increase the speed at which it is transmitted. This causes premature contraction of the ventricles and tachycardia (rapid heart rate).

When coupled with cardiac dysrhythmia (irregular heart beat), individuals with an accessory pathway have an increased risk of ventricular fibrillation. Severe tachycardia may lead to cardiogenic shock (inadequate blood circulation due to premature ventricular contraction/arrhythmia). These create a very small risk of sudden cardiac death, occurring in approximately <0.6% of WPW sufferers.

Symptoms

Many people may remain asymptomatic throughout their lives however symptoms most commonly found in WPW patients are:

Chest pain or tightness

Dizziness

Syncope (fainting)

Palpatations

Shortness of breath

Diagnosis (using an ECG when in normal sinus rhythm)

A delta wave can often be observed (manifested as a slurred upstroke beginning the QRS complex). 

Short PR interval <120milliseconds

Widened QRS complex >120milliseconds

Treatment of WPW is a destruction of the abnormal electrical pathway by radiofrequency catheter ablation (an invasive procedure involving flexible catheters being threaded through the patients blood vessels to the heart and an electrical impulse being given to destroy the accessory pathway).

Zoe Pollock, 10, gives “Jalouise” the donkey her first trim. A pack of hairy donkeys have had their dreadlocks cut for the first time in 17 years to help them keep cool in the hot weather. The rare French breed, called Baudet du Poitou, are not meant to be groomed, so their coat is left to grow into long dreadlocks. Picture: Zachary Culpin/ Solent News & Photo Agency
