In the present research, free convection heat transfer from isothermal concave and convex body shapes is studied numerically. The body shapes investigated here, are bi-sphere, cylinder, prolate and cylinder with hemispherical ends; besides, they have the same height over width (H/D = 2). A Numerical simulation is implemented to obtain heat transfer and fluid flow from all of the geometries in a...

Objective(s): Curcuminoids, comprising curcumin, demethoxycurcumin (DMC) and bisdemethoxycurcumin (BDMC), are bioactive phytochemicals with numerous pharmacological effects. Oral biological availability of curcuminoids is low due to the low aqueous solubility and rapid metabolism. This study aimed at fabricating a nanomicellar curcuminoid formula with enhanced pharmacokinetic properties. Materi...

‎the water wave generation by wave paddle and a freely falling rigid body are examined by using an incompressible smoothed particle hydrodynamics (isph)‎. ‎in the current isph method‎, ‎the pressure was evaluated by solving pressure poisson equation using a semi-implicit algorithm based on the projection scheme and the source term of pressure poisson equation contains both of divergence free ve...

PURPOSE Free tumor cells in peritoneal fluid in patients with pancreatic cancer may have prognostic significance but there are few reports on methods for the effective detection of free tumor cells. The aims of this study were to identify free cancer cells in peritoneal fluid with fluorescent in situ hybridization (FISH) technique and to investigate its prognostic significance. METHODS Twenty...

CONTEXT No molecular biological tests are available to monitor the ongoing development of human fetuses in vivo. OBJECTIVE To determine whether cell-free fetal messenger RNA (mRNA) in amniotic fluid can be detected using oligonucleotide microarrays to study large-scale gene expression in living human fetuses, with analysis of sex, gestational age, and fetal pathology as variables. DESIGN, S...

background: despite a high prevalence of endometriosis, there still exist many challenges in diagnosing the disease. this study aims to evaluate non-invasive and practical diagnostic methods by measuring serum and peritoneal fluid ca 125 levels in patients with endometriosis. a secondary aim is to determine the correlation between these markers with the stage of disease as well as the relations...

BACKGROUND Ultrasound is being used increasingly to diagnose pathological free fluid accumulation at the bedside. In addition to the detection of peritoneal and pericardial fluid, point-of-care ultrasound allows rapid bedside diagnosis of pleural fluid. FINDINGS In this short report, we describe the sonographic observation of the vertebral or 'V-line' to help confirm the presence of pleural f...

in plasma and showed that filterable GAPDH mRNA species are present, and therefore likely to be particle bound, whereas the majority of ␤-globin DNA is not filterable and thus is not particle bound. Our study analyzed cell-free nucleic acids in amniotic fluid for the presence of particle-associated mRNA species , and like Ng et al. (7), we found the greatest decrease in GAPDH mRNA after filtrat...

We investigate barotropic perfect fluid cosmologies which admit an isotropic singularity. From the General Vorticity Result of Scott, it is known that these cosmologies must be irrotational. In this paper we prove, using two different methods, that if we make the additional assumption that the perfect fluid is shear-free, then the fluid flow must be geodesic. This then implies that the only she...
