Photorefra.tive crysta.s present va.ied fea.ures cha.ming presence, such a. high resolution, a.d norma. ha.dling. Depending on the porta.ility of era.ing ima.es, photorefra.tive crysta.s a.e convenient for rea.-write implementa.ions a.d hence find potentia. use in speckle photogra.hy, speckle interferometry, ima.e processing a.d hologra.hy. a.two-bea. coupling a.ra.gement using a.LiNbO3 crysta. a. a.recording medium for rea.-time rota.ion mea.urement using the coherent a.d low-power la.er source is presented in this pa.er. a.speckle photogra.hy technique is a.va.ced for the mea.urement of a.sma.l rota.ion of a.tra.smitted gla.s slide sa.ple. New theoretica. a.a.ysis is formula.ed for a.genera. ca.e of a.slide rota.ion. Experimenta. studies a.e ca.ried out to verify the outcome of the theoretica. predictions a.d a.cura.y of mea.urement. Uncerta.nty of rota.ion mea.urement is studied a.d qua.tified. The proposed technique is a.simple, a.tra.tive a.d a.terna.ive method for fringe a.a.ysis. The method promises a.high degree of a.cura.y a.d increa.ed ra.ge for rota.ion mea.urement in rea.-time.

Mn-Ferrite na.opa.ticles were prepa.ed using citra.e a.to combustion method. The prepa.ed sa.ple wa. cha.a.terized by X-ra. diffra.tion (XRD), HRTEM a.d BET to mea.ure the pa.ticle dia.eter a.d the surfa.e a.ea.of the prepa.ed sa.ple. The da.a.of XRD cla.ified tha. the sa.ple wa. formed in single pha.e spinel structure without a.y extra.pea.s indica.ing non-existence of a.y seconda.y pha.e. The HRTEM microgra.h indica.ed tha. the pa.ticles were in a. a.glomera.ed sta.e due to the a.sence of surfa.ta.t a.d high ma.netic properties of Mn-Ferrite na.opa.ticles. The mecha.ica. properties were mea.ured a. different ra.ios of na.o-Ferrite to concrete. The obta.ned va.ues of mercury intrusion porosimetry (MIP) indica.ed tha. the a.dition of Mn-Ferrite na.opa.ticles increa.ed the compressive strength a.d decrea.ed the tota. intrusion volume. This wa. due to the ra.id consuming of Ca.OH)2 which wa. formed during hydra.ion of Portla.d cement especia.ly a. ea.ly a.es due to the high rea.tivity of MnFe2O4 na.opa.ticles. Moreover, MnFe2O4 na.opa.ticles recovered the pa.ticle pa.king density of the blended cement, lea.ing to a.reduced volume of pores in the cement pa.te.

Most of developing countries suffer from decrea.ing a.d poor qua.ity of drinking wa.er which led to emergence of ma.y da.gerous disea.es. In a.dition, there isn’t a.y methodology followed to predict a.d disinfect drinking wa.er by using a.va.ced softwa.e progra.. Ma.nta.ning wa.er qua.ity in the wa.er distribution system ha. become a.prominent issue in the study of the wa.er network. Residua. chlorine concentra.ion is the indica.or to ensure the qua.ity of wa.er in the wa.er network beca.se it elimina.es conta.ina.ts in the distribution network beginning of the trea.ment pla.t down to the consumer. In colla.ora.ion with a.exa.dria.(Egypt) Wa.er Compa.y, sa.ples were ta.en from El-NOZHa.wa.er pla.t sta.ion a.d El-Ha.a.a.wa.er distribution network to know the free residua. chlorine. In this pa.er, Wa.erCa. softwa.e ha. been used to ma.e hydra.lic a.a.ysis a.d ca.ibra.ion of residua. chlorine in wa.er distribution network to know the idea. chlorine dose tha. should be a.ded a. the wa.er trea.ment pla.t a.d to know the a.ea. of strength a.d wea.ness in the concentra.ion of free residua. chlorine in the wa.er distribution network. In a.dition different scena.ios ha.e been found to know the free residua. chlorine a. the wea.ness a.ea. a.ter injecting chlorine in some junctions a.d the impa.t of a.fire ca.e or brea.ing in the wa.er pipe distribution network on the residua. chlorine. Results showed ensuring in the wa.er qua.ity in the distribution network by a.ding chlorine dose in wa.er less tha. the existing dose which ha. been a.ded in the El-NOZHa.wa.er trea.ment pla.t. It is possible to ma.nta.n the percenta.e of free residua. chlorine concentra.ion a. different loca.ions without relying on a.ding chlorine only in wa.er trea.ment pla.t by injecting low percenta.e of chlorine dose in the junctions.

This study wa. underta.en to explore new a.tifunga. compounds from the metha.olic extra.t of G. sina.cus. Two ca.denolide compounds were isola.ed a.d identified by GC-MS a. ca.denolide glycoside, 15-hydroxy-3,4,5,6-dehydroca.otropin a.d ca.denolide genin, 3,4,5,6-dehydroca.otropa.enin. The a.tifunga. a.tivity of these compounds wa. a.sessed. Results revea.ed tha. both compounds showed pronounced fungicida. a.tivity a.a.nst both soil borne fungi, R. sola.i, F. oxysporium, a.d postha.vest fungi, R. stolonifer, P. digta.um, compa.ed to the sta.da.d fungicides, flutola.il a.d copper oxychloride, respectively. The ECs0 va.ues of the ca.denolide genin were 0.703, 13.63 a.d 4.22, 8.403 la./mL forR. sola.i, F. oxysporium a.dR. stolonifer, P. digta.um respectively. On the other ha.d, the ECs0 va.ues of the sta.da.d fungicide, flutola.il, were 9.49 a.d 61.22 ~tg/mL a.a.nst R. sola.i a.d F. oxysporium. While the ECso va.ues of copper oxychloride were 279.94 a.d 187.13 p.g/mL a.a.nst R. stolonifer a.d P. digta.um, respectively. The results showed tha. cellula.e, PME, PPO of the tested fungi wa. more sensitive tha. to ca.denolide genin. The strong a.tifunga. a.tivity of ca.denolide genin reported in this study indica.ed tha. ha. a.potentia. to be used a. fungicides.

Objective: To compa.e ma.erna. a.d feta. outcome a.socia.ed with two methods Reverse breech extra.tion versus Hea. pushing to deliver the impa.ted feta. hea. in a.va.ced la.or requiring emergency Cesa.ea. section. Method: a.prospective compa.a.ive study wa. conducted on 80 pregna.t women a. term with cepha.ic presenta.ion in a.va.ced la.our, requiring emergency Cesa.ea. Section. Reverse breech extra.tion technique (pull method) wa. used in 40 ca.es (group I) a.d pushing the hea. up through the va.ina.(“push” method) wa. tried in (group II) 40 ca.es. The ma.erna. outcome wa. a.sessed by extension of the uterine Incision, bla.der injury, intra.a.d postopera.ive blood tra.sfusion, Postpa.tum hemorrha.e, wound infection a.d dura.ion of hospita. sta.. Feta. outcome wa. a.ga. score a.d a.mission to neona.a. intensive ca.e unit. Results: Extension of the uterine incision wa. significa.tly lower in women undergoing reverse breech extra.tion compa.ed to cepha.ic delivery (20% versus 50%;p = 0.001). The mea. opera.ive time (pull group) wa. lower tha. tha. in the (push group) 59.7 ± 4.2, versus 75.2 ± 6.1 p = 0.001 a.d blood loss wa. significa.tly lower in the (pull group) tha. tha. in the (push group) 878 ± 67 ml, versus 1321 ± 57 ml, p = 0.001. No significa.t difference between groups rega.ding ma.erna. a.d neona.a. outcome. Conclusion: Reverse breech extra.tion (pull) is sa.er tha. pushing hea. up through va.ina.(push) for delivery of a.deeply impa.ted feta. hea. in a.va.ced la.our sensitizing emergency Cesa.ea. Section a.d is a.socia.ed with the lea.t ma.erna. complica.ions.
