Laminar Flow In Mini-Fluidics Channels Assembly And Its Application In Zebra Fish Embryo Research, Radek Glaser Dec 2007

Laminar Flow In Mini-Fluidics Channels Assembly And Its Application In Zebra Fish Embryo Research, Radek Glaser

Radek Glaser

A Mini-Fluidics system was designed to facilitate the muscle growth of the Zebra Fish embryos. This experimental device is made of peristaltic pump, inflow/outflow manifolds, fluid storage tank, series of valves and flexible pipes and the main plate with six mini channels. These closed channels provide pathways for an extremely laminar flow. The Zebra Fish embryos are placed in the channels and exposed to the forces present in the fluid.


Self-Assembly Of Nanoparticles At Interfaces, Alexander Böker, Jinbo He, Thomas P. Russell, Todd S. Emrick Sep 2007

Self-Assembly Of Nanoparticles At Interfaces, Alexander Böker, Jinbo He, Thomas P. Russell, Todd S. Emrick

Todd S. Emrick

Developments in the assembly of nanoparticles at liquid–liquid interfaces are reviewed where the assemblies can be controlled by tuning the size of the nanoparticles and the chemical characteristics of the ligands. Both synthetic and biological nanoparticles are discussed. By controlling the type of ligands, uniform and Janus-type nanoparticles can be produced where, at liquid–liquid interfaces, subsequent reactions of the ligands can be used to generate crosslinked sheets of nanoparticles at the interface that have applications including novel encapsulants, filtration devices with well-defined porosities, and controlled release materials. By controlling the size and volume fraction of the nanoparticles and the chemical …


The Concept Of Resources In Triz, Umakant Mishra Aug 2007

The Concept Of Resources In Triz, Umakant Mishra

Umakant Mishra

An ideal system should have all advantages and no harms. If the resources consumed are expensive than the output produced then the invented system becomes ridiculous. The objective should be to use least amount of resources, cheapest resources, easily available resources and resources available within the system.

Every system intends to achieve a main useful function. The use of resources should target to improve its main useful function. If certain parts of a system or certain resources lead to unwanted functions or harmful effects then that part of the system needs to be modified and those resources need to be …


Quantum Dots Coordinated With Conjugated Organic Ligands: New Nanomaterials With Novel Photophysics, Nathan L. Hammer, Todd S. Emrick, Michael D. Barnes Jun 2007

Quantum Dots Coordinated With Conjugated Organic Ligands: New Nanomaterials With Novel Photophysics, Nathan L. Hammer, Todd S. Emrick, Michael D. Barnes

Todd S. Emrick

CdSe quantum dots functionalized with oligo-(phenylene vinylene) (OPV) ligands (CdSe-OPV nanostructures) represent a new class of composite nanomaterials with significantly modified photophysics relative to bulk blends or isolated components. Singlemolecule spectroscopy on these species have revealed novel photophysics such as enhanced energy transfer, spectral stability, and strongly modified excited state lifetimes and blinking statistics. Here, we review the role of ligands in quantum dot applications and summarize some of our recent efforts probing energy and charge transfer in hybrid CdSe-OPV composite nanostructures


R&D Management In Iran, Opportunities And Threats, Nader Ale Ebrahim, Ali Ghazizadeh, Arash Golnam, Hamid Tahbaz Tavakoli May 2007

R&D Management In Iran, Opportunities And Threats, Nader Ale Ebrahim, Ali Ghazizadeh, Arash Golnam, Hamid Tahbaz Tavakoli

Nader Ale Ebrahim

Research and Development (R&D) management in Iran has faced many barriers and obstacles, in which R&D units are considered as the basic core of the product development and innovation. Due to structural shortcomings, a great number of organizations and industries have not yet been able to position themselves in the market. There are about 1141 R&D units throughout Iran, due to the geographical decentralization of these units this paper considers and analyzes the R&D case study in one of the provinces located in the north part of Iran, and the findings can be generalized to the other industrialized areas and …


Design And Characteristics Of A Split Hopkinson Pressure Bar Apparatus, Radek Glaser, Jesse Haines, Christopher Knight May 2007

Design And Characteristics Of A Split Hopkinson Pressure Bar Apparatus, Radek Glaser, Jesse Haines, Christopher Knight

Radek Glaser

A Split Hopkinson Pressure Bar Apparatus, also known as Kolsky Bar that is capable of conducting compressive strain rate testing in the approximate ranges from 50 to 10^4 in/in per second was designed as a part of a Senior Design Project. Generally, this device is similar to that first used by Kolsky in 1949. The design of this device is presented here in two stages: 1. Research, design and manufacturing of the Stress Generating System 2. Experimental Part – Testing of the apparatus to obtain necessary data. The present phase of the design was focused mostly on the stress generating …


Outsourcing The Packaging Function, Rihaz Z. Chughatta Apr 2007

Outsourcing The Packaging Function, Rihaz Z. Chughatta

Rihaz Z Chughatta

If you are currently working in the packaging department of a major corporation in the pharmaceutical, food or consumer products industry, you have probably been exposed to some form of outsourcing, which is a global trend that has emerged over the past decade, and continues to evolve, within the packaging field.


Derivation And Application Of A Conserved Orbital Energy For The Inverted Pendulum Bipedal Walking Model, Jerry E. Pratt, Sergey V. Drakunov Mar 2007

Derivation And Application Of A Conserved Orbital Energy For The Inverted Pendulum Bipedal Walking Model, Jerry E. Pratt, Sergey V. Drakunov

Sergey V. Drakunov

We present an analysis of a point mass, point foot, planar inverted pendulum model for bipedal walking. Using this model, we derive expressions for a conserved quantity, the “Orbital Energy”, given a smooth Center of Mass trajectory. Given a closed form Center of Mass Trajectory, the equation for the Orbital Energy is a closed form expression except for an integral term, which we show to be the first moment of area under the Center of Mass path. Hence, given a Center of Mass trajectory, it is straightforward and computationally simple to compute phase portraits for the system. In fact, for …


Sleepers Exposed: New Innovations In Rail Design, Sakdirat Kaewunruen Jan 2007

Sleepers Exposed: New Innovations In Rail Design, Sakdirat Kaewunruen

Sakdirat Kaewunruen

No one would deny that our rail network makes life much easier, and trains are widely considered to be the world's safest mode of transport. Bearing this in mind, the idea of decreasing the weight of railway sleepers, or increasing the load they carry may make passengers and associates of the rail industry sceptical as regards their own safety or the integrity of their goods and assets.
