Recently, n-type Si solar cells featuring a passivated rear contact, called TOPCon (Tunnel Oxide Passivated Contact) were reported.
An experimental study of the transport properties of fluid-saturated joints composed of two complementary rough fracture surfaces, translated with respect to each other and brought in contact, is reported.
Surprisingly, only one contact was reported with a person that the respondent had never met before.
A TB contact was reported outside of the household in 298 children (19.7%), inside the household, but excluding the child's mother, in 551 children (36.4%), and a maternal TB contact was reported in 144 children (9.5%).
In one subset of participants (n = 1328) for whom a history of a household TB contact was reported at baseline, the prevalence of a positive baseline TST and QFT was significantly and negatively associated with time since TB contact exposure (Table 4); i.e. the longer the time since last recalled contact, the lower the proportion with a positive result on either test.
One confirmed GAS case in a household contact was reported (attack rate, 66.1/100,000 household contacts).
The first HIV infection via homosexual contact was reported in Chongqing in 2005.
Most reports of direct contact involved monkeys (73.7%), although some direct contact was reported with gorillas (16.7%) and chimpanzees (9.6%).
In total, 133 (23.5%) web-based survey contacts had concordant reports (i.e., the contact was reported by both participants) and 432 (76.5%) contacts were reported by only one study participant, but not by the other.
If a contact was reported by only one participant in a pair, then the lower duration value is 'not reported'.
