Objective: The a.m of the work is to eva.ua.e the a.cura.y of intra.pera.ive frozen section in the dia.nosis of ova.ia. neopla.ms in Za.a.ig University. Design: a.prospective cross sectiona. cohort study. Method: This study wa. performed between Ma.ch 2011 a.d Ma.ch 2012, on 50 pa.ients presented with ova.ia. ma.s. Gross exa.ina.ion of the tumor removed wa. done by inspection a.d pa.pa.ion. The specimen wa. then cut with a.sha.p knife into two ha.ves. The most a.propria.e a.ea.thought to be representa.ive of lesion wa. chosen. The number of sections frozen wa. depended on the type a.d size of the tumor. Seven to eight μm sections were obta.ned a.d sta.ned with hema.oxylin-eosin. The specimens were then fixed in forma.in. Pa.a.fin blocks of the sections were processed in the routine wa. a.d sections were sta.ned with hema.oxylin a.d eosin (H a.d E). The dia.nosis obta.ned by intra.pera.ive frozen section ba.ed on cellula.ity a.d cell morphology wa. compa.ed with fina. histopa.hologica. dia.nosis in terms of dia.nostic sensitivity, to differentia.e between benign a.d ma.igna.t lesions. a.sessment of the overa.l a.cura.y of the intra.pera.ive dia.nosis wa. cla.sified a. concorda.t or discorda.t. Results: There wa. no sta.istica.y significa.t differencre in the studied pa.ients a. rega.d the clinica. da.a. ma.roscopic a.d intra.pera.ive picture, while there wa. sta.istica.y significa. a.socia.ion a. rega.d the la.era.ity of the ova.ia. ma.ses. The va.idity of frozen section in the dia.nosis of benign tumour wa. 100% with 100% a.cura.y, specificity, positive predictive va.ue, nega.ive predictive va.ue, while sensitivity & nega.ive prediction for borderline tumour a.d specificity & positive prediction of ma.igna.t tumour were 100%, specifecity for borderline tumours wa. 95% while the positive predictive va.ue wa. 33.3% with 96% a.cura.y for both ma.igna.t a.d borderline tumours. Conclusion: Intra.pera.ive frozen section is a.cura.e for ra.id dia.nosis of ova.ia. tumors. I

A composite material is made up of two phases, the matrix, and the reinforcing materials. The reinforcing material is embedded over matrix material. The reinforcing material works to make the matrix material harder. A fibreglass reinforced composite was developed using E-glass fibre reinforcement and epoxy resin matrix. The composites were produced using the hand lay-up technique with varying fibre percentage of 9%, 13% and 25% by weight percentage of fibreglass mat at orientations of 0°, 15°, 45°, a.d 90° chosen a. ra.dom. a.13% by weight percenta.e of chopped ma. wa. a.so developed for purpose of compa.ison. The fa.rica.ed composites were subjected to tensile test, flexura. test, impa.t test, punch shea. test a.d ha.dness test to a.certa.n the a.propria.e fibre contents a.d orienta.ion tha. is optimum for the ma.ufa.ture of hea.gea.s. a.a.ysis of Va.ia.ce wa. ca.ried out to determine level a.>of significance and percentage contribution of the parameters. The results show that both fibre orientation and percentage of fibre content reinforcement of have significant influence on the strength and fracture energy of the composite .The fibre orientation has a higher impact on the strength of the composite (79.74%) while the percentage of fibre reinforcement has a lesser impact on the tensile strength of the composite (20.26%). a.>a.>However, a.>a.>a. style="font-fa.ily:Verda.a.">a. style="font-fa.ily:Verda.a.">a. style="

Sol-gel is a.promising technique for the synthesis of orga.ic-inorga.ic hybrid ma.eria.s of cla.s II. One of the most interesting a.plica.ions for these hybrid ma.eria.s is a. solid polymer electrolytes (SPEs). In pa.ticula., when doped with proton species they ha.e potentia. a.plica.ions in fuel cells. In this pa.er SiO2–PEG1500 hybrids of cla.s II were prepa.ed with different contents of SiO2 a.d phosphotungstic a.id. The influence of the SiO2 content in the ma.rix ha. been studied. The sa.ples were investiga.ed by therma. a.a.ysis (TGa.a.d DSC), X-ra. diffra.tion, infra.ed spectros-copy (IR), sca.ning electron microscopy (SEM) a.d Impeda.ce Spectroscopy.

2D position sensitive, single-sided Si stripixel detector wa. selected a. the one of the two ma.n components of the Si vertex tra.ker (Si SVX) in the upgra.ed PHENIX detector a. RHIC (rela.ivistic hea.y ion collider) in Brookha.en Na.iona. La.ora.ory (BNL). This is the first la.ge sca.e a.plica.ion of the novel Si stripixel detector in a.rea. la.ge experiment a.ter ma.y yea.s of resea.ch a.d development a. BNL. The first a.d second prototype fa.rica.ion runs of the SVX stripixel detectors were ca.ried out successfully in BNL’s Si detector development a.d processing La.. The processing of these stripixel detectors is simila. to tha. for the sta.da.d single-sided strip detectors: one-sided processing, single impla.t for the pixel (strip) electrodes, etc. The only a.ditiona. processing step is the double meta. process, a.technology tha. is simple a.d well ma.ured by ma.y Si detector processing industries a.d la.s, including BNL. The la.er a.d bea. tests on those prototype detectors show the 2D position sensitivity a.d good position resolution in both X a.d U coordina.es (a.out 25 μm for 80 μm pitch). For the ma.s production of 400 sensors needed for the Si SVX, the processing technology ha. been successfully tra.sferred to the industria.: Ha.a.a.su Photonics (HPK). HPK ha. produced a.pre-production run of stripixel sensors with the full PHENIX SVX specifica.ion on 150 mm dia.eter wa.ers. The la.er tests on these pre-production wa.ers show good signa. to noise ra.io (a.out 20∶1).
