The argument for the privatization of state enterprises is based on the superior efficiency of private over state ownership. This argument is only true when it ignores the institutional constraints including insecure property rights enforcement, land, credit, and export-quota policies. By using a survey of ninety-six textile-garment enterprises in Vietnam, private and foreign enterprises were f...

ic changes in the anus and nearby structures of patients with anal incontinence, perineal sepsis, and anal tumors (1). From a technical viewstand, most work groups currently operate 7to 10-MHz transducers allowing 360o, high-resolution images. The study is performed with no previous intestinal preparation and having the patient lye on his/her left side with both legs flexed 90o; except for rare...

OBJECTIVE As the consequences of Mycoplasma genitalium in pregnant women are unknown, we examined the relationship between prenatal M. genitalium infection and SAB. METHODS The presence of M. genitalium was determined by PCR in urine from 82 women who subsequently experienced a SAB and 134 women who maintained their pregnancies past 22 weeks gestation. The relationships between M. genitalium ...

Hysteresis patterns of different sediment particle sizes were studied via a detailed laboratory study and modelling. Seven continuous rainfall events with stepwisevarying rainfall intensities (15, 30, 45, 60, 45, 30 and 15 mmh-1, each 20 min duration) were conducted using a 5-m× 2-m erosion flume. Flow rates and sediment concentration data were measured using flume discharge samples, and interp...

A terrain M is the graph of a bivariate function. We assume that M is represented as a triangulated surface with N vertices. A contour (or isoline) of M is a connected component of a level set of M. Generically, each contour is a closed polygonal curve; at “critical” levels these curves may touch each other or collapse to a point. We present I/Oefficient algorithms for the following two problem...

Using lateral intake is a method of floodwater diverting. In arid and semi-arid areas, floodwatercontains a large amount of sediment that will be carried in to the intakes and it causes a reduction inchannel conveyance. Sediment is almost transported into the intake and it is settled in the upstreamside of lateral channel. Sedimentation in this zone reduces the conveyance of lateral channel and...
