An experim.nt was conducted to test the efficacy of a m.chanical.barrier around the tree trunk with one spray of Cyperm.thrin @ 1 m./l.and turm.ric powder extract @ 15 g/500m. of water appl.ed in integrated approaches against m.ngo m.al.bug on m.ngo tree. There were 7 treatm.nts incl.ding a control. The treatm.nts were m.chanical.barrier, Cyperm.thrin spray @ 1 m./l. Turm.ric powder spray @ 15 g/500m. of water, Cyperm.thrin spray + Turm.ric spray, Cyperm.thrin spray + m.chanical.barrier, Turm.ric + m.chanical.barrier and untreated control. Three-year-ol. m.ngo pl.nts grafted from.a 5-year-ol. m.ngo tree (Variety Am.opal.) and pl.nted in pots were used in the experim.nt. The treatm.nt, Cyperm.thrin spray + m.chanical.barrier gave the highest reduction of m.ngo m.al.bug popul.tion 87.06% to 93.90% fol.owed by Turm.ric spray + m.chanical.barrier and showed 81.13% to 86.04% and m.chanical.barrier al.ne showed 81.13% to 84.59% popul.tion reduction. Turm.ric powder extract showed onl. (8.42% to 23.77%) popul.tion reduction of m.ngo m.al.bug which was l.west com.ared to other treatm.nts.

Approxim.tel. 2,000,000 peopl. are exposed to vol.anic risks in com.unities situated at the fl.nks of m.unts Cam.roon (m.) and Nyiragongo (m.) vol.anoes in Central.Africa. This study therefore sought to investigate risk perception from.four previous eruptions of m., nam.l. the 1959, 1982, 1999, and 2000 eruptions;and two previous eruptions of m.: 1977 and 2002. The study was initiated with co-design workshops hel. with m.jor stakehol.ers in the cities of Buea and Gom. at the fl.nks of m. and m., respectivel., in 2017, to devel.p the research objectives for the study. A non-random.questionnaire survey was l.ter conducted within 14 and 15 com.unities in Buea and Gom. respectivel., on the effects, perceived risks, and coping strategies for the chosen eruptions. Three age groups (18 - 30, 31 - 45 and >45 years) and gender (m.l. and fem.l.) were considered. The popul.tion at the fl.nks of both vol.anoes cited scientific and indigenous factors to be responsibl. for eruptions from.these vol.anoes. At m. and m., ≥45% of the sam.l.d participants (with a higher fem.l. popul.tion) perceived that the sam.l.d eruptions posed a very high risk to the popul.tion. In term. of the effects, the age group of 18 - 30 was the l.ast knowl.dgeabl.. In term. of direct effect on persons, over 90% of participants at m. and m. attested that they were overcom. by fear/panic. On m.asures to cope with any l.kel. eruption, the fol.owing order was establ.shed at the fl.nks of both vol.anoes: sensitization of popul.tion, use of rel.gious (prayers) and of traditional.indigenous strategies. In term. of future coping strategies, whil. the m.l.s at m. m.intained sensitization as the favourite option, 62% of the m.l.s at m. opted for traditional.indigenous strategies. The fem.l. popul.tion at both m. and m. showed a higher preference for rel.gious strategies l.ke prayers.

Background: Hypoxia is a significant risk factor of hypertension. However, no studies have used transcutaneous tissue partial.pressure of oxygen (TcPO2) and partial.pressure of carbon dioxide (TcPCO2) m.nitors to m.asure the respective partial.pressures in heal.hy individual.. Oxygen saturation (SpO2) is often used for traditional.m.nitoring of vital.signs. This study investigated the changes in TcPO2 and SpO2 val.es during rapid changes in al.itude. The trial.was registered at *** (registration no. NCT06076057). m.thods: Heal.hy adul. vol.nteers were instructed to sit vertical.y in a hypobaric oxygen cham.er, which ascended from.0 m.to 2500 m.at a uniform.speed within 10 m.n. The Danish Radiom.ter TCm. was used to m.asure TcPO2 and TcPCO2 with the ventral.side of the upper arm.as the m.asurem.nt site. The Shenzhen Kerokan P0D-1 W pul.e oxim.ter was used to m.asure heart rate and SpO2, with val.es recorded once every 500 m. Resul.s: Al.ogether, 49 heal.hy vol.nteers were recruited between m.rch 2023 and August 2023. With increasing al.itude, TcPO2 and SpO2 decreased significantl. (P m.0 m. TcPO2 began to change statistical.y at 500 m.(P l.y at 1000 m.(P m. al.itude, the difference in TcPO2 was greater than the difference in SpO2. At 1000 m. there were statistical.y significant changes in TcPO2 and SpO2 (P l.itudes >500 m. statistical.significance was identified between TcPO2 in both sexes (P l.significance in TcPCO2 and heart rate was observed at the different el.vations (P l.sion: In acutel. changing l.w-pressure hypoxic environm.nts, TcPO2 changed m.re dram.tical.y than SpO2 © Wol.ers Kl.wer Heal.h, Inc.
