The thermal dissipation performance of sintered heat pipes is usually determined by the capillarity and permeability of the Cu powder wicks. Since the capillary provided by the Cu powder is usually large enough to draw water from the condenser end to the evaporator end, the permeability has become the controlling factor. In this study, Cu powders with different particle sizes and shapes were loosely sintered, and their permeabilities were compared. The results show that more complicated shapes, finer particle sizes, lower porosities, and rougher pore surfaces give lower permeability and thermal dissipation.

Partial 9p deletion syndrome and partial 18q duplication syndrome each have distinct clinical features. We describe the prenatal molecular cytogenetic analysis of a de novo unbalanced karyotype with deletion of 9p23-pter and duplication of 18q12.2-qter in a mild dysmorphic female fetus. Fetal ultrasonography was performed and detailed karyotype analyses were conducted using a combination of G-banding, SKY analysis and FISH with chromosome arm specific sub-telomeric DNA probes and chromosomal region specific BAC clone probes. The fetal sonography and fetal echocardiography at 17 weeks’ gestation did not reveal any anomaly while the fetus had a large unbalance karyotype of 46,XX,der(9)t(9;18) (p23;q12.2) de novo. Its external phenotype at 21 weeks appeared to have some mild dysmorphic features including hypertelorism, low-set ears, micrognathia/retrognathia, clenched hands and rocker bottom feet. These dysmorphic features are seen in the Edward syndrome but with milder degrees.
