Modeling Of Mixing Time For Bioreactors With Self-Inducing Impellers, Alaa K. M.

Baghdad Science Journal

the mixing time is one of the most useful criterions for characterization of the broths mixing intensity and for scaling up of biosynthesis processes. this parameter value depends mainly on the presence of biomass in the broths, mixing system characteristics and operating conditions. For quantifying the influence of these factors on mixing efficiency, this study was carried out for simulated fermentation aerated broths consisted of carboxymethyl cellulose sodium salt (CMCNa) taking into account the broth's viscosity, rotation speed (rpm) and the stirrer geometry. The experimental results were used in obtaining a correlation to calculate the mixing time for Re <5000, domain of flow regime for which only few data are available from literature. t_m=1.6x10^3xμ^0.43_a/N^1.13X L^0.53 This model offer a good concordance with the experimental results, the average deviation being of 6.6% for CMCNa solutions and can be used for fermentation scaling up.

The Epidemiology Of Giardia Spp. Infection Among Pet Dogs In The United States Indicates Space-Time Clusters In Colorado, Ahmed S. Mohamed, George E. Moore, Elizabeth Lund, Larry T. Glickman

GIS Day

Giardia infection has been found in a wide range of hosts including human, domestic, and wild animals. Dogs are the definitive host of G.duodenalis, which can cause diarrhea and other symptoms. Although zoonotic transmission of Giardia remains unclear, epidemiologic evidence suggests that some Giardia species are zoonotic. Additionally, Giardia has been associated with epidemics in the US and other countries making it one of the most important public health concerns. Prevalence of Giardia among dogs in the United States ranged from 10% in well-treated dogs to 30-50% in puppies and up to 100% in breeding kennels. However, prevalence of Giardia …

Attrition In Adolescent After-School Programs: Addressing The Concern Via Interviews With Program Dropouts, Lynda Okeke

Journal of Youth Development

The purpose of this paper is to address the challenges of attrition in adolescent, voluntary after-school programs (ASPs). Studies show that the after-school hours are a time of elevated juvenile delinquency. Since 1998 there has been a surge in the number of ASPs throughout the United States. Despite this surge, attrition is a major concern and threat to ASPs. Moreover, youth who drop out are rarely asked about their reasons for not attending. Seventy middle school-aged individuals who were selected to participate in the Baltimore County Middle School After-School Collaboration Project (BCAP) but eventually dropped out are interviewed for this …

Glypican-1 Modulates The Angiogenic And Metastatic Potential Of Human And Mouse Cancer Cells, Takuma Aikawa, Chery A. Whipple, Martha E. Lopez, Jason Gunn, Alison Young, Arthur D. Lander, Murray Korc

Dartmouth Scholarship

Cells isolated from many types of human cancers express heparin-binding growth factors (HBGFs) that drive tumor growth, metastasis, and angiogenesis. The heparan sulfate proteoglycan glypican-1 (GPC1) is a coreceptor for HBGFs. Here we show that both cancer cell–derived and host-derived GPC1 are crucial for efficient growth, metastasis, and angiogenesis of human and mouse cancer cells. Thus downregulation of GPC1 in the human pancreatic cancer cell line PANC-1, using antisense approaches, resulted in prolonged doubling times and decreased anchorage-independent growth in vitro as well as attenuated tumor growth, angiogenesis, and metastasis when these cells were transplanted into athymic mice. Moreover, athymic …

Electrothermal Imaging In One And Two Dimensions, Michael Janus, David Kibbling

Mathematical Sciences Technical Reports (MSTR)

Developing methods for the nondestructive testing of materials is an important area of research for industry. Situations often arise in which the integrity of an object is questioned, but testing it is very difficult. For example, a support bar may be embedded in a larger structure so that testing the bar’s integrity directly would require the impractical task of breaking down the larger structure. Instead, the ends of the bar might be accessible without dismantling the enclosing structure. The goal of nondestructive testing is to use methods that require taking measurements at the ends of the bar alone to give …
