Frameworks for reprogramming early diverging land plants
… frameworks for reprogramming of the early diverging land plant Marchantia polymorpha (Marchantia). I describe the generation of genomic and transcriptomic datasets for Marchantia, which has provided the basis for the compilation of a gene-centric registry of DNA parts for engineering …

Dense gas effects in a converging-diverging nozzle
… of steady inviscid flows in a converging-diverging nozzle are presented for a general fluid. The main emphasis is placed on Bethe-Zel'dovich-Thompson fluids, i.e., those having specific heats so large that the fundamental derivative of gasdynamic is negative over a finite range of …

Characterization of microparticle velocities in converging-diverging nozzle systems
… experimental system incorporating a converging-diverging nozzle to accelerate well characterized particles to high speeds via aerodynamic drag force on the particle and measures the resulting velocities. Velocity measurements in the range of 0.3 - 1 km s-1 were taken for singularly sized of …

Measurements on supersonic plasma flow in a diverging channel
The isolated effect of divergence angle on nozzle performance and the variation of nozzle performance over a wide range of divergence angles are determined. Data for nozzles with area ratio of 200, which vary in conical half angle from 10 to 45 degrees, are included. An analytical expression is …

Saudi students and IEP teachers: converging and diverging perspectives
This research investigates the perspectives of teachers and Saudi students in an Intensive English Program (IEP) on the necessary skills for international students’ success in American university classes, the IEP’s effectiveness in developing those skills, and on the role of high-stakes …

Evolution of Transcription in Archaea and the Early-Diverging Eukaryote, Giardia Lamblia
… survey of transcription components in an early-diverging eukaryote. It is apparent that the evolution of transcriptional machinery can be subdivided into the evolution of a core system and the evolution of a peripheral set of factors modulating the activity and specificity of the core. We see …

Development and characterization of a diverging cusped field thruster and a lanthanum hexaboride hollow cathode
… type thrusters. The design, referred to as a Diverging Cusped Field (DCF) thruster, employs aspects of both existing cusped field thrusters and traditional Hall thrusters while including several unique design features aimed at increasing performance. In addition to supporting competitive …

Foucauldian Micropolitics and the Evolution of Party Polarization: Diverging Discourses in America's Two-Party System
… only have the parties been deploying drastically diverging discourses on issues of biopolitical administration, but this also tends to engender political saliency on issues in which voters were not significantly concerned. There are certainly insidious implications for a representative system of …

Experimental Investigation of Dimples as a Heat Transfer Enhancement Feature in Narrow Diverging and Converging Channels
… have been obtained for narrow converging and diverging channels with and without enhancement features. The enhancement feature considered for this study is dimples (inline and staggered) on the main heat transfer surfaces. All the measurements are presented at Reynolds numbers of 3500, 8900, …

Study of Delay Calculation for Diverging Diamond Interchange and Safety Assessment of Ecodriving on Following Traffic
Diverging diamond interchanges (DDI) have been proved to outperform other types of diamond interchanges in terms of safety, cost-effectiveness and efficiency, but few research efforts have been done to conduct the analytic calculation of delay, with which optimization of timing plans can be …

Converging intentions, diverging realities : rights vs. growth-based approaches to safe sanitation provision in Addis Ababa, Ethiopia
Although we are now well into the twenty first century, the possibility of achieving equitable, universal access to water and sanitation is still out of reach for most cities. According to a progress report by the WHO/UNICEF Joint Monitoring Program, in 2015, 844 million people lacked even the most …

Performance characterization and optimization of a diverging cusped field thruster with a calibrated counter-weighted millinewton thrust stand
The previously developed Diverging Cusped Field Thruster (DCFT) has undergone further investigations and performance characterization. The DCFT is a magnetically conned plasma thruster that uses cusped magnetic fields to confine electron ow and reduce losses to the walls. The magnetic confinement …

Frontex and the diverging interests of particular member states of the EU facing the challenge of irregular migration in the central Mediterranean : case study : Italy and Malta
… The research will also aim at assessing how. the diverging interests (of different member states) can be reconciled within a European Agency such as Frontex. The study will focus on the EU's Central Mediterranean member states: Italy and Malta, which means that an elaboration on the idea of burden …

Numerical Predictions of Flow-Induced Fiber Orientation in Three-Dimensional Geometries
… flow, axisymmetric expansion flow, and radially diverging flow in a thin cavity. For the axisymmetric contraction and expansion, the flow patterns for the fiber suspension and for the suspending fluid alone were distinctly different. Results from numerical simulation of the contraction were found …

Impact of Lens Angle and Nozzle Geometry on Aerodynamic Focusing: A Numerical Study
… such as capillaries, converging nozzles, and diverging nozzles. The focusing performance of these other geometries has not been systematically evaluated. This study used computational fluid dynamics (CFD) simulations and Lagrangian particle tracking to investigate aerodynamic focusing of …
