In 1986, when Hibbs was thirty five, the Soviet reactor at Chernobyl, in Ukraine, melted down. Hibbs began to travel to the Soviet Union to report on its nuclear industry, a subject still largely hidden from view. The puzzle fascinated him. He was a fast learner, capable both of grasping physical technicalities and, more important, of navigating the complex political terrain that surrounds the use of nuclear power. His interest in the field expanded worldwide. By then he had found his outlet, too, and was writing for Platts, which soon hired him full time. For a while he wrote only about civil nuclear power. To anyone outside the industry it was mind numbing stuff. But beneath the surface in Europe was action of a different sort: though the Nuclear Non Proliferation Treaty NPT had come into force, and parallel protocols had been agreed upon to restrict the export of materials necessary for the construction of nuclear bombs, enforcement was lax, and individual companies, particularly in Germany, were eagerly doing business with a growing number of nuclear weapons aspirants. Much of the business was questionable but not obviously illegal; for the most sensitive items it involved dealings with middlemen who worked through front companies and third country destinations and provided the sellers with usable explanations. Then as now, European attitudes were soft despite official abhorrence of such activities, because in private the nuclear non proliferation initiativesaccompanied as they were by repeated U.

Ribbon diagram was obtained from Wrapp et al. ,1 chemical structures were from PubChem and Nieto Garai et al. 2It is widely known that interfering with the lipid envelope represents a virucidal strategy to target many coronaviruses, with a large body of work evidencing the impact of many agents. 18,19 For a summary, refer to Kampf et al. , a systematic review providing tables showing data from different original publications for inactivation of coronaviruses by biocidal agents in suspension tests. 19 During the 2003 SARS CoV outbreak, viral material was detected on hospital surfaces, leading to the idea that surface decontamination would be an important approach. At that time, various compounds were considered, including ethanol at high concentrations of 60%70% v/v, since these doses had been found to be highly effective against several viral pathogens, including coronaviruses. 1921 Recent studies on SARS CoV 2 also support this, with high concentrations being highly effective as shown in a recent preprint. 22 The historical reason for only testing high concentrations in microbicidal research has been that these give broad spectrum activity toward bacteria, viruses, and fungi, and thus for use on inanimate surfaces/fomites where the target microbes are unknown would be always preferred. The consensus view is that enveloped viruses, such as herpesviruses, orthomyxoviruses, paramyxoviruses, and coronaviruses are highly sensitive to 60%70% v/v ethanol with almost immediate inactivation, while nonenveloped viruses are less or not susceptible. 1922We are now widely encouraged to use soap or 60%70% alcohol based gels to inactivate SARS CoV 2, based on the view that these agents damage the lipid envelope, including in recent World Health Organisation WHO and Environmental Protection Agency recommendations HO WPE GIH 2020.

We hadto return the rifles to the Armoury and collectoveralls, and memorise the number of our rifle. Wewere told always to check the number of the riflewhen collected; and another oft repeated pearl ofwisdom: "Check the number and you will neverclean someone elses rifle. "The number of non swimmers was notdiminishing very rapidly so it was arranged that oneafternoon each week, when they were at the swimmingpool, we swimmers would muster at the basement andscrub and blanco the webbing gear of the squadsrifles. Overalls on for this job and the seaman incharge of the Armoury collected a penny from each ofus for a mug of tea when Stand Easysounded off. Naval jargon again, his part was knownas running a tea boat, and most welcomeit was. We learned to stop climbing around the riflesand instead have the rifles climb around us. Aspecial piece of metal was fitted to the rifle: itspurpose was to fit it together with two other riflesto stack them in the form of a tripod. There weresome frozen moments when we piled arms,stacking them in the threes, and marched off to heara clatter as one or more stacks collapsed because ofinsufficient care or being too hastily piled. Thenext of drill with the rifle was to learn to fixbayonets The drill order was carried out upon hearingthe two words "Fix Bayonets" and with itcame the old salts rendering of that order. Itgoes something like this in its Westcountryrendering: "When I says Fix doan ee move, butwhen I says Bayonets, you whips em out, one,one two. An mind ee dont lop yeroppos yers off.
