eight sites were sampled during seven rain events to quantify and identify the sources ofpolycyclic aromatic hydrocarbons in urban runoff in the city of tijuana, mexico. the total σ16 pahsconcentration rangedfrom 1113 to 4866 μg/lin the sampled sites and thetotal suspended solid concentrations ranged from 7725 to 4413 μg/l. the high concentrations of total suspended solids were probably the res...

background: we sought to assess right ventricular (rv) systolic and diastolic functions via tissue doppler imaging (tdi) in order to discriminate right-to-left (bidirectional) from left-to-right intracardiac shunts. methods: a tissue doppler velocity study via doppler echocardiography was performed in 20 patients with left-to-right shunt (without evidence of significant pulmonary hypertension) ...

objectives: this study aimed to assess the diagnostic value of conventional and digital radiography for detection of cavitated and non-cavitated proximal caries. materials and methods: fifty extracted human premolars and molars were mounted in a silicone block. charge-coupled device (ccd) and photostimulable phosphor plate (psp) receptors and intra-oral films were exposed with 60 and 70 kvp wit...
