In this study, degradation of p-chlorophenol (p-CP) was evaluated using persulfate (PS) activated zerovalent iron (ZVI) based ultraviolet (UV) in a bench scale photoreactor. The effect of operational parameters such as solution pH (3, 7, and 11), reaction time (0-60 minutes), ZVI dosage (0.15, 1.25, 0.5, 1, and 1.5 mM), PS concentration (0.5, 1.5, 2, 2.5, 3, and 4 mM), and initial p-CP concentr...

We propose and demonstrate a polarization-time coding (PTC) method which can effectively compensate both the CD and first order PMD in direct-detected OFDM transmission. Compared with the previous methods, the proposed PTC not only alleviates the need for the complex dynamic polarization controller but also exhibits superior transparencies to both the OFDM format and transmission data rate. For...

children with cerebral palsy (cp) suffer from several problems, so the family especially the mothers undertake a lot of social and emotional difficulties. the purpose of this study was to determine the severity of depression in mothers of children with cp in comparison with mothers who have normal children and its relation to the type of cp and severity of the disability. during this descriptiv...

Sir, Creatine Kinase (CK) E.C. 2.7.3.2. is separable into three different isoenzymes by a number of methods. Each isoenzyme is a dimer composed of two subunits (Bor M) each having a relative molecular mass of 40,000. These isoenzymes are widely distributed in tissues, CK-MM and CK-MB are found mainly in the skeletal and heart muscles and CK-BB in G.l. tract and the brain with small amounts also...

The expression of cytokeratins (CKs) 8, 18 and 19 was analyzed in male and female rat gonads from the undifferentiated stage (12.5 days of gestation) until two weeks after birth by indirect immunofluorescence, using specific monoclonal antibodies anti-CK 8 (LE41), anti-CK 19 (LP2K) and anti-CK 18 (LE65 and RGE53). In the undifferentiated blastema, the somatic cells were stained for CK 8 and CK ...

The study investigated the relationship between Iranian EFL teachers' perception of critical pedagogy (CP) and reflective teaching (RT), the possible effect of gender, academic degree, and teaching experience on teachers’ perceptions of CP, the possible differences among the three groups of teachers of universities, public schools and private language institutes regarding their perception of CP...
