في ذكرى انطلاقة الثورة السورية – 18 آذار

Standard

في ذكرى انطلاقة الثورة السورية في 18 آذار (مارس) 2011، إطلاق وسم #ارفع_علم_ثورتك للتأكيد على المُضي قُدمًا في الثورة حتى إسقاط اللانظام اﻷسدي وبناء سوريا حُرَّة وجديدة.

الثورة السورية ثورة عُمدَّت بالحديد والنار لتُعيد للسعب السوري كرامته وحربته يعد عقود من اﻻستبداد والطغيان.

A Former F1 Doc Writes

No matter how you slice it, Fernando’s decision to not drive in Australia is a proof of his intelligence, maturity, and understanding of “the big picture”. My assumption is that he is suffering from concussion. Although there are curious elements in the story we’ve been told, if we “simply” put together a few relatively objective tidbits, they would appear to spell “concussion”:

  1. an impact to the head
  2. talk of loss of consciousness
  3. talk of retrograde amnesia (loss of memories of events BEFORE the trauma)

What we’re worried about is twofold. In order of importance this would be: concern about a driver whose brain was not functioning optimally at the helm of an F1 car, and concern about second impact syndrome.

That’s why it’s crucial that all symptoms and signs (respectively subjective and objective) of concussion are totally resolved…

Effects of High Voltage Transmission Lines on Humans and Plants

Standard

Electrical Notes & Articles

 Introduction:

By increasing population of the world, towns are expanding, many buildings construct near high voltage overhead power transmission lines. The increase of power demand has increased the need for transmitting huge amount of power over long distances. Large transmission lines configurations with high voltage and current levels generate large values of electric and magnetic fields stresses which affect the human being and the nearby objects located at ground surfaces. This needs to be investigating the effects of electromagnetic fields near the transmission lines on human health.

The electricity system produces extremely low frequency electromagnetic field which comes under Non ionizing radiations which can cause health effects. Apart from human effect, the electrostatic coupling & electromagnetic interference of high voltage transmission lines have impact on plants and telecommunication equipments mainly operating in frequency range below UHF.

IS Power Line EMF safe? This is the controversy Discussion directly eludes…
