Western governments seem to be in no doubt that president Bashir Al Assad is responsible for what appears to be a deadly Chemical Weapons attack in Idlib Province which has killed dozens of people including at least eleven children and injured hundreds more. The foreign secretary Boris Johnson said if proved then it is a war crime. The Un Security Council is holding an Emergency Meeting tomorrow to discuss the attack. If assad is the culprit, something the Syrian Regime denies, then it is surely evidence that he believes he can act with impunity not least because russia is his ally, and the white house has recently stated its priority is not removing assad but defeating is. But today the white house pointed the finger of blame at barak obama saying that these heinous actions are a consequence of the last administrations weakness and irresolution. President obama said in 2012 he would establish a red line against the use of Chemical Weapons and then he did nothing. Before we discuss the
Minimally invasive surfactant therapy had mixed results in a 2-year follow-up study of a randomized clinical trial of preterm infants with respiratory distress syndrome who were supported with CPAP.
Dust exposure in open pit mines is a significant threat to the health of mine workers. Particularly, the concerns are around respirable crystalline silica dust, which can be inhaled into the lungs and cause serious health issues. Miners who are exposed to high concentrations of PM2.5 dust for an extended period of time run the risk of acquiring respiratory conditions like silicosis and lung damage. Drilling is the first production-related operation in open pit mines, and it is considered one of the major sources of respirable dust in mines. This study investigates the application of surfactants in reducing PM2.5 dust resulting from drilling operations in open pit mines. Experiments are conducted on laboratory prepared sandstone blocks to compare the dust reduction rates of the surfactant to those of dry drilling and water-based wet drilling. Rotation rate, feed rate and the surfactant/water flow rate are the drilling variables altered in order to investigate the performance of the surf
What do personal care products like shampoo and cleaning products such as detergents have in common? They contain surfactants which facilitate the mixing of generally immiscible substances such as oil and water. Click to read more.
Finnish biotechnology start-up Montinutra has partnered with personal care company Ole Hyvä Luonnontuote to use an ingredient from the by-products of spruce sawmilling, which it claims is a natural and eco-friendly surfactant.
