One of the m.st com.only used equa.ions to estim.te soil erosion is the revised universa. soil loss equa.ion (RUSLE). Ba.ed on the ea.ly a.proa.h developed by the Soil Conserva.ion Service of USa. the ra.nfa.l erosivity fa.tor (R-fa.tor) in the RUSLE equa.ion requires sub-da.ly ra.nfa.l da.a. which is usua.ly not a.a.la.le. Other em.irica. equa.ions estim.te R-fa.tor ba.ed on a.a.la.le ra.nfa.l da.a.like a.nua. a.d m.nthly ra.nfa.l da.a. In a.id regions such a. the a.a.ia. Peninsula. severa. studies estim.ted the R-fa.tor ba.ed on these em.irica. equa.ions without ca.ibra.ion. We propose in this pa.er to a.sess the a.plica.ility of som. of these em.irica. equa.ions a.a.nst R-fa.tor va.ues ca.cula.ed using a. a.reference the RUSLE a.proa.h. For this da.a. da.a.from.104 sta.ions with sub-da.ly ra.nfa.l wa. collected. The reference R-fa.tor wasa.>a.> calculated for the 104 stations. The results of seven empirical equations were tested against the reference R-factor. Most of the tested equations significantly underestimated the R-factor. Furthermore, the obtained RMSE and MAE values were almost as high as the average R-factor, with MAPE exceeding 100%. Therefore, it is recommended not to apply these equations in arid regions. A recalibration of the form of equation that gave the best results, gave aa.>a.>na.>a.> RMSE of 280 (Mj·m./(ha.16}hr)) a.d the m.PE dropped to 47.6%.a.>a.>a.>

a.m. We a.tem.ted to illustra.e our experience of fetoscopic thera.y in a.tertia. institute, whereby to highlight the present Egyptia. situa.ion rega.ding this issue. We described fetoscopic thera.y undergone a. a.-Hussein Hospita., a.-a.ha. University, Ca.ro, Egypt, from.Dec-2012 to Sep-2019. Presenta.ion of ca.es: Sixteen wom.n with 17 fetuses were included in the a.a.ysis of this study with a.m.a. a.e of 25.31 ± 6.15 yea.s;four with positive m.rria.e to a.nea. releva.t, a.d eight were prim.gra.ida. The fetus of twelve wom.n ha. lower urina.y tra.t obstruction (LUTO), two feta. a.em.a. one hydrothora., a.d one twin-to-twin tra.sfusion syndrom. (TTTS). The m.a. tim. for fetoscopy wa. gesta.iona. week 24.13 ± 3.77. We did thera.eutic dra.na.e to a.0}iotic fluid in hydrothora. a.d LUTO, thera.eutic septostom. to the TTTS ca.e, a.d blood tra.sfusion in ca.es of feta. a.em.a. During the opera.ion, the procedure succeeded in 14 out of 16 wom.n. Overa.l, nine of the 16 wom.n experienced som. com.lica.ions;five with rupture of m.m.ra.es, four with preterm.la.or, a.d three with intra.terine feta. dea.h (IUFD). Conclusion: Fetoscopy ca. m.na.e LUTO a.d well-selected ca.es of TTTS, hydrothora., a.d feta. a.em.a. The procedure is prom.sing. Fetoscopic thera.y ha. just begun in Egypt, a.d this report m.y contribute to the future a.va.ce of fetoscopic thera.y in Egypt.
