Aim: To.examine the pro.ile and presentatio. o. a co.secutive series o. giant retinal tears (GRTs) in an African po.ulatio.. Also.to.review the clinical state o. the patient’s fello. eyes. Metho.: A retro.pective o.servatio.al case series o. thirty-six co.secutive eyes o. 36 patients with a GRT retina detachment that had vitreo.etina surgery do.e between April 2006 and June 2013. All info.matio. was extracted fro. the patient’s case reco.ds. Result: Thirty-nine case reco.ds had surgery co.secutively within the study perio.. Three case reco.ds had inco.plete data and were excluded fro. the analysis. Thirty-six eyes were analyzed. There were mo.tly males (80.6%), age range 21 - 65 yrs (mean age 47 yrs). The co.mo.est etio.o.y was idio.athic (21 eyes). Presenting visual acuity was mo.tly in the co.nting finger and hand mo.io. range (83%), and the mean presenting intrao.ular pressure was 6.8 mmHg. Mo.t o. the eyes presented with a to.al retina detachment (4 quadrant invo.vement;56%), macular invo.vement (96%), co.mo.est size o. the retina tear being between 90 to.180 degrees in 20 eyes;ro.led o.er retina flap (61%) and advanced grades o. PVR being very co.mo. (83%). The co.mo.est fello. eye event no.ed was blindness in 16 fello. eyes;while 12 eyes had pro.hylactic retina laser pho.o.o.gulatio. to.peripheral predispo.ing retina lesio.s. Co.clusio.: The presentatio. o. GRT in a lo. reso.rce co.ntry is o.ten as a co.plex retina detachment situatio., which may arise fro. frequent delays to.assess care and o.her so.io.co.o.ic issues. This carries significant implicatio.s o. pro.no.is fo.lo.ing surgical interventio.. Also.this study raises the awareness that fello. eyes o. GRT in Africa are at increased risk o. blindness and require mo.e careful attentio..

The technique o. pro.ucing hydro.en by utilizing green and renewable energy so.rces is called green hydro.en pro.uctio.. Therefo.e, by implementing this technique, hydro.en will beco.e a sustainable and clean energy so.rce by lo.ering greenho.se gas emissio.s and reducing o.r reliance o. fo.sil fuels. The key benefit o. pro.ucing green hydro.en by utilizing green energy is that no.harmful po.lutants o. greenho.se gases are directly released thro.gho.t the pro.ess. Hence, to.guarantee all o. the enviro.mental advantages, it is crucial to.co.sider the entire hydro.en supply chain, invo.ving sto.age, transpo.tatio. and end users. Hydro.en is a pro.ising clean energy so.rce and targets plan pathways to.ards decarbo.izatio. and net-zero.emissio.s by 2050. This paper has highlighted the techniques fo. generating green hydro.en that are needed fo. a clean enviro.ment and sustainable energy so.utio.s. Mo.eo.er, it summarizes an o.erview, o.tlo.k and energy transient o. green hydro.en pro.uctio.. Co.sequently, its perspective pro.ides new insights and research directio.s in o.der to.accelerate the develo.ment and identify the po.ential o. green hydro.en pro.uctio.. Hydro.en is a pro.ising clean energy so.rce and a pathway to.ards decarbo.izatio. and net-zero.emissio.s by 2050. This article pro.ides perspective o. techniques fo. generating green hydro.en that are needed fo. a clean enviro.ment and sustainable energy so.utio.s. Graphical Abstract

This paper pro.o.es an adaptive metho. based o. fuzzy lo.ic that utilizes data fro. phaso. measurement units(PMUs) to.assess and classify generating-side vo.tage trajecto.ies. The vo.tage variable and its asso.iated derivatives are used as the input variables o. a fuzzy-lo.ic blo.k. In additio., the vo.tage trajecto.y is co.pared with the pre-selected pilo.-bus vo.tage to.make a reliable decisio. abo.t the vo.tage o.eratio.al state. Different types o. sho.t-term vo.tage dynamics are co.sidered in the pro.o.ed metho.. The fuzzy membership functio.s are determined using a systematic metho. that co.siders the current situatio. o. the vo.tage trajecto.y. Finally, the vo.tage status is catego.ized into.fo.r classes to.determine appro.riate remedial actio.s. The pro.o.ed metho. is validated o. a IEEE 73-bus po.er system in a MATLAB enviro.ment.
