A continuous forced flow electrophoresis cell and a method of operation for the fractionation of an aqueous liquid, such as blood, containing at least two compounds, the relative mobilities of which in an electric field vary as a function of the pH, in order to obtain one fraction enriched and one depleted in one of the compounds, the cell having six compartments divided by ion permeable membranes, the end cell containing an anode and cathode respectively, the central cells being separated by a microporous membrane. The liquid is fed to one of the central cells the filtered fraction being removed, after passage through the microporous membrane, from the other. A main electrolyte is fed to and from the end cells and an auxiliary electrolyte to the intermediate cells such that the pH in one intermediate cell differs from that of the other.
A method for the isolation of brush-border membranes from newborn-rat kidney, employing centrifugation and free-flow electrophoresis, is described. The composition and purity of the preparation was assessed by determination of enzyme activities specific for various cellular membranes. Free-flow electrophoresis resolves the newborn-rat renal membrane suspension into two populations of alkaline phosphatase-enriched brush-border membranes, designated A and B, with the A peak also showing activity of (Na+ + K+)-stimulated ATPase, the basolateral membrane marker enzyme, whereas those of the B peak were enriched 11-fold in alkaline phosphatase and substantially decreased in (Na+ + K+)-stimulated ATPase activity. Membranes in the A peak showed a 7-fold enrichment of alkaline phosphatase, and (Na+ + K+)-stimulated ATPase activity similar to that of the original homogenate. Proline uptake employed to assess osmotic dependency revealed 7% binding of proline to the B vesicles and 31% to the A vesicles. ...
Fig 1. Principle of free-flow electrophoresis. The miniaturization of FFE implies several advantages especially considering sample volume and separation speed. In contrast to the tens of milliliters of sample consumed by conventional large scale FFE devices, microfluidic FFE systems require only tens of nanoliters up to hundreds of microliters of sample. This is especially interesting in clinical analysis where often only low sample volumes are available. Furthermore, instead of residence times of up to tens of minutes, microfluidic FFE (µ-FFE) devices separate within several seconds. The aim of this project is to develop a microfluidic free-flow electrophoresis device (as shown in figure 2 and 3) which eventually might find application in so called proteomics-on-a-chip systems for proteome analysis.. ...
Temperature-gradient gel electrophoresis (TGGE) was employed to determine the thermal stabilities of 48 DNA fragments that differ by single base pair mismatches. The approach provides a rapid way for studying how specific base mismatches effect the stability of a long DNA fragment. Homologous 373 bp DNA fragments differing by single base pair substitutions in their first melting domain were employed. Heteroduplexes were formed by melting and reannealing pairs of DNAs, one of which was ³²P-labeled on its 5-end. Product DNAs were separated based on their thermal stability by parallel and perpendicular temperature-gradient gel electrophoresis. The order of stability was determined for all common base pairs and mismatched bases in four different nearest neighbor environments; d(GXT) d(AYC), d(GXG) d(CYC), d(CXA) d(TYG), and d(TXT) * d(AYA) with X,Y = A,T,C, or G. DNA fragments containing a single mismatch were destabilized by 1 to 5°C with respect to homologous DNAs with complete Watson - Crick ...

We also observed significantly increased accuracy in size-based fractionation of microbeads as compared to previously presented FFA multiple outlet systems. Fluorescence microscopy illustrates the importance of two-dimensional prefocusing where a sample mixture of 3, 7, and 10 mu m beads are separated into well-confined particle streams and collected in their respective target outlets. Flow cytometry data for lymphocytes and granulocytes, respectively, in their corresponding outlets verify concurrent isolation of leukocyte subpopulations with high purity (95.2 +/- 0.6% and 98.5 +/- 0.7%) and high recovery (86.5 +/- 10.9% and 68.4 +/- 10.6%).

Although the phenomenon we now call dielectrophoresis was described in passing as far back as the early 20th century, it was only subject to serious study, named and first understood by Herbert Pohl in the 1950s.[9][10] Recently, dielectrophoresis has been revived due to its potential in the manipulation of microparticles,[2][4][5][11]nanoparticles and cells. Dielectrophoresis occurs when a polarizable particle is suspended in a non-uniform electric field. The electric field polarizes the particle, and the poles then experience a force along the field lines, which can be either attractive or repulsive according to the orientation on the dipole. Since the field is non-uniform, the pole experiencing the greatest electric field will dominate over the other, and the particle will move. The orientation of the dipole is dependent on the relative polarizability of the particle and medium, in accordance with Maxwell-Wagner-Sillars polarization. Since the direction of the force is dependent on field ...

This thesis presents two new concepts for separation of micro particles using dielectrophoresis, demonstrated by calculated examples, as well as a new method for obtaining dielectric data on living cells. The thesis is based on four papers.. Paper I describes how the trapping efficiency of micro particles may be significantly increased when superpositioned electric fields are employed in a high conductivity medium. Avoiding low conductivity media is important when working with living cells.

Paper II proposes a new concept for separation of micro particles, based on repetitive dielectrophoretic trapping and release in a flow system. Calculations show that the resolution increases as a direct function of the number of trap and release steps, and that a difference in ...

Although bacterial culture remains the gold standard for detection of viable bacteria in environmental specimens, the typical time requirement of twenty-four hours can delay and even jeopardize appropriate determination. In addition, culture is incapable of detecting viable but not culturable (VBNC) species. Conversely, nucleic acid and antibody-based methods decrease time to detection but rarely characterize viability of the bacteria detected. Through selection by membrane permeability, the method described in this work employs positive dielectrophoresis (pDEP) for separation and purification of viable and VBNC species from water and allows concentration of bacteria for downstream applications.

A device for holding an IV tube in a pumping apparatus and for selectively occluding the tube when the door of the pumping apparatus is opened, to prevent free flow of fluid in the tube. The device consists of a base member to which the IV tube is attached or through which it passes, and a slide clamp which slides relative to the base member and relative to the tube. The IV tube is passed through an elongated aperture in the slide clamp, and the slide clamp is slidingly mounted on the base member. The aperture in the slide clamp has a relatively open hole at one end, through which the tube passes when the slide clamp is in one position, allowing fluid to flow through the tube. The aperture also has a relatively constricted slot at the other end, through which the tube passes when the slide clamp is in a second position, preventing fluid flow through the tube. A flexible cantilevered arm on the base interlocks with a locking projection on the slide clamp to lock the slide clamp in the second

The Global Information Locator Service (GILS) encompasses a global vision framed by the fundamental values of open societies. Societal values such as a free flow of information impose certain requirements on the societys information infrastructure. These requirements in turn shape the various laws, policies, standards, and technologies that determine the infrastructure design. A particular focus of GILS is the requirement to provide the means for people to discover sources of data and information. Information discovery in the GILS vision is designed to be decentralized yet coherent, and globally comprehensive yet useful for detailed data. This article introduces basic concepts and design issues, with emphasis on the techniques by which GILS supports interoperability. It explains the practical implications of GILS for the common roles of organizations involved in handling information, from content provider through system engineer and intermediary to searcher. The article provides examples of GILS

Previously, we tried to predict 90th percentile evacuation time $T{90}$ determined from ABM simulation using 90th percentile free flow clearance time $T90f$. Bigger the city, greater we can expect $T90f$ to be since it would take longer to traverse. Plotting $T90f$ vs $T90$ produces the figure below. $T90f$ under predicts $T90$ with a poor fit ($R=0.31$) but it is clear that $T90$ is never less than $T90f$! Since that did not work out too well, I attempt to predict $T90$ using the knowledge of how the population is distributed distance $D$ from the exit.

Summary: A 16S rRNA-based molecular ecological study was performed to search for dominant bacterial sequences in Drentse A grassland soils (The Netherlands). In the first step, a library of 165 clones was generated from PCR-amplified 16S rDNA. By sequence comparison, clone DA079 and two other identical clones could be affiliated to a group of recently described uncultured Actinobacteria. This group contained 16S rDNA clone sequences obtained from different environments across the world. To determine whether such uncultured organisms were part of the physiologically active population in the soil, ribosomes were isolated from the environment and 16S rRNA was partially amplified via RT-PCR using conserved primers for members of the domain Bacteria. Subsequent sequence-specific separation by temperature-gradient gel electrophoresis (TGGE) generated fingerprints of the amplicons. Such community fingerprints were compared with the TGGE pattern of PCR-amplified rDNA of clone DA079 which was generated with the
Article: Smith, James P.; Huang, Chao; Kirby, Brian J.; (2015) Enhancing Sensitivity and Specificity in Rare Cell Capture Microdevices with Dielectrophoresis, Biomicrofluidics, 9(1). DOI. Abstract: The capture and subsequent analysis of rare cells, such as circulating tumor cells from a peripheral blood sample, has the potential to advance our understanding and treatment of a wide range of diseases. There is a particular need for high purity (i.e., high specificity) techniques to isolate these cells, reducing the time and cost required for single-cell genetic analyses by decreasing the number of contaminating cells analyzed. Previous work has shown that antibody-based immunocapture can be combined with dielectrophoresis (DEP) to differentially isolate cancer cells from leukocytes in a characterization device. Here, we build on that work by developing numerical simulations that identify microfluidic obstacle array geometries where DEP-immunocapture can be used to maximize the capture of target ...

Carbon nanomaterials have a large surface area and complex particles shape architecture. These qualities are successfully applying to develop new drug carriers, fillers, or nanodetectors [1]. At the same time, the utilization efficiency of such materials is caused by maintaining of the nanodispersity. An agglomeration and partially sedimentation of nanotubes in aqueous media is a well-known fact. The stability of the nanotube dispersion mostly depends on the uniformity of the boundary layer and nanotube morphology. The hydrophobic nature of defectless areas of their surface and the hydrophilicity of some types of defects in the nanotube boundary layer, namely carboxy- or phenolic groups [2, 3] which are formed during nanotube purification and washing, are competing during dispersing in the aqueous media. An increase in stability of the nanotube dispersion in water can be achieved through the surface charge via formation of the double electrical layer (EDL). Among other carbon materials, carbon ...
Fluid-Screen, Inc. presents a bacterial concentration and filtration method based on dielectrophoresis (DEP). DEP has been known to induce particle motion since the 1960s. However, yields and reproducibility have consistently been low in practice, reducing the potential of DEP for practical applications. Here we present a novel electrode design to induce high electric field gradients. This design allows rapid and efficient capture of diverse bacteria from aqueous solutions of varied conductivity. By using the novel spiral electrode design and tuning the electric field to species-specific frequencies, we show capture of over 99% of bacteria within seconds of gradient application. Our method of DEP induces responses in both the representative Gram-negative Escherichia coli and Gram-positive Enterococcus faecalis bacteria. Equilibrium repositioning of suspended bacteria can be seen within miliseconds for low-conductivity medium and within seconds for higher conductivity solutions such as environmental

The present disclosure is directed to a novel apparatus and novel methods for the separation, characterization, and manipulation of matter. In particular, the invention combines the use of frequency-dependent dielectric and conductive properties of particulate matter and solubilized matter with the properties of the suspending and transporting medium to discriminate and separate such matter. The apparatus includes a chamber having at least one electrode element and at least one inlet and one output port into which cells are introduced and removed from the chamber. Matter carried through the chamber in a fluid stream is then displaced within the fluid by a dielectrophoretic (DEP) force caused by the energized electrode. Following displacement within the fluid, matter travels through the chamber at velocities according to the velocity profile of the chamber. After the matter has transmitted through the chamber, it exits at the opposite end of the chamber at a characteristic position. Methods according to

In order to point out the driven forces in the loading and release of protein onto thermally sensitive poly(N-isopropylacrylamide) (NIPAM) nanogel particles, which largely claimed in drug delivery and analytical processes, various polyNIPAM based nanogel particles were prepared, and the loading and release of two model proteins: bovine serum albumin (BSA) and -Globulins (G), onto various cationically or anionically charged polyNIPAM nanocrogel particles were investigated. At first, the nanogels particles were well characterized regarding their colloidal properties (swelling ability, particle size, and electrokinetic properties). Then, the loading and release of proteins behaviour onto the elaborated particles were investigated as a function of temperature, pH, and salinity. It was found that the loaded amount of both proteins increases as a function of temperature irrespective of the nature of charge of polyNIPAM nanogels. The protein loaded amount onto the two lower charged polyNIPAM ...

An activated carbon fiber composite for separation and purification, or catalytic processing of fluids is described. The activated composite comprises carbon fibers rigidly bonded to form an open, permeable, rigid monolith capable of being formed to near-net-shape. Separation and purification of gases are effected by means of a controlled pore structure that is developed in the carbon fibers contained in the composite. The open, permeable structure allows the free flow of gases through the monolith accompanied by high rates of adsorption. By modification of the pore structure and bulk density the composite can be rendered suitable for applications such as gas storage, catalysis, and liquid phase processing.

A recent WHO review of the PIP Framework offered an opportunity to close major gaps but also revealed the texts rigidity in adapting to rapid scientific progress (10). GSD fundamentally change the paradigm within which the PIP Framework operates, potentially rendering the framework less effective.. In the short run, it would be best simply to interpret the framework to include GSD as biological materials. Keeping GSD under the umbrella of a global agreement would facilitate tracking sequencing data, while holding users accountable-facilitating socially productive research, while limiting harmful use. A tracking system need not be burdensome or restrict the free flow of scientific information. A simple registration system that monitors who has downloaded GSD would help ensure that recipients abide by global research norms and could be incorporated into existing databases such as the GISAID platform. Moreover, allowing free exchange of GSD without enforcing the obligations owed to the donating ...

Modifications of the package include a Stage 2 Upgrade, Dinan Free Flow Stainless Exhaust, Carbon Fiber Cold Air Intake, High Performance Adjustable Coil-Over Suspension System, Sway Bars, Pedal Cover Set, and of course an under the hood plaque and deck lid badge for proof of the modifications. Other than the Dinan labeled black exhaust tips, this M3 gives fairly stock appearance with its Carbon Fiber Diffuser and by not flaunting any badge on the trunk other than the Black M Badge.. Being as powerful a vehicle as the M3 is, making sure it can stop properly is important. Stopping isnt a problem for this M3 with its M Carbon Ceramic Brakes and Yellow Calipers that not only prove it, but also add on to the clean appearance of the car. Keeping the black badging and trimming consistent, ...
Did you know that private companies can patent genes in your body? A company called Myriad Genetics owns two genes known as BRCA 1 and BRCA2 -or Breast Cancer 1 and Breast Cancer 2. Women with certain mutations in these genes have a strong chance of getting breast or ovarian cancer.. This has very dangerous implications for womens health and scientific research.. The government should not be granting private entities control over something as personal and basic to the human body as our genes. Moreover, granting patents that limit scientific research, learning and the free flow of information violates the First Amendment.. ...
Plaque, a combination of cholesterol, fat, and other substances starts to stick to the walls lining your blood vessels which builds up over time. This makes arteries become harder and narrower,resulting in atherosclerosis.These plaques can break or rupture, by which blood cells called platelets will try to repair the artery, forming a blood clot. This buildup prevents a free flow of blood through the arteries. Blood carries oxygen and nutrients to the heart. If you dont get enough, it can lead to shortness of breath and chest pain (angina).. ...
AP Photo/Nati Harnik. Mike Pence speaks at a campaign stop in Council Bluffs, Iowa in August 2016.. Although Mike Pence has won praise for championing a proposed federal shield law to protect journalists sources, the Indiana governors overall First Amendment record is mixed.. When he was in the U.S. House of Representatives, Pence several times was one of the two leading sponsors of the Free Flow of Information Act, a bill to protect reporters from being compelled to reveal confidential sources or information. While 39 states and the District of Columbia have shield laws, there is no such protection on the federal level.. The push for a federal shield law has been unsuccessful to date, but Pences advocacy for freedom of the press earned him bipartisan admiration.. He was a terrific champion for reporters and their rights to maintain the confidentiality of sources, and I think that history needs to be noted, said Rick Boucher, a former Democratic congressman from Virginia who co-sponsored ...
But making hydrogen requires energy too. Making nitrogen fertilizers uses lots of hydrogen, so those serious about fuel supplies will also have to worry about food supplies. I just wish the same people who talk about shutting down industries and exacting revenge would instead busy themselves with showing that alternatives can be successfully commercialized, because if they cant theres little sense in using them. Energy independence will not come from government investing in unworkable alternatives. Energy independence can only come from the use and exploitation of domestic energy sources and this includes coal. Oil and related hydrocarbons are intrinsically cheap. If we decide to move away from them because we dont like or cant shoulder the associated problems, e.g., keeping the free flow free, wed better prepare for somebody else doing the dirty jobs. And to the winner goes the spoils ...

Snoring causes a person to wake up throughout the night. For most, snoring is simply a case of having to move your body from a bad position into one thats more comfortable to breathe in. But for the 18 million people in the United States suffering from OSA, snoring is their bodys cry for help. Throughout the night people with OSA literally stop breathing. They stop breathing because the muscles in their mouth, jaw, and throat relax, blocking the free flow of air in the airway. These moments of suffocation can last for up to an entire minute. A person with OSA wakes up hundreds of times during a single night as their bodies try not to suffocate. Snoring is their bodys only way to get enough air to breathe. ...
Some states, particularly members of the Non-Aligned Movement (NAM), see Article III on nonproliferation and Article X on promotion of peaceful use of biotechnology as equally important. They interpret Article X as an obligation for developed countries to share their expert knowledge with less-developed countries. Several states feel that developed countries have not fulfilled this obligation, and have called for the establishment of a formal mechanism for scientific cooperation. A few states also oppose the view that compliance with the BTWCs Article III necessitates national strategic trade controls, which in their view restrict the free flow of biological technology and knowledge.. Other states view disarmament and nonproliferation as the primary goal of the BTWC. Therefore, the aim of Article X is principally to ensure that the nonproliferation goals of the treaty do not hinder peaceful activities. These states are generally supportive of strategic trade controls and view them as necessary ...
If we are truly engaged in trying to understand the world we live in we need to busy ourselves with observation. Not looking properly, not seeing things are the common reasons why we fail to understand. We tend to be very quick at drawing conclusions without allowing the full experience of watching and observing to collect its information inside our system. And so it is with ear candling too. I have heard many explanations but sadly most of them dont even pass a simple observation test. However, when we observe we also have to guard ourselves, as much as we can, against wanting to see a certain thing and in doing so failing to see what is really important.. Lets put this into some practice. Take any type of ear candle you like and remove whatever device acts as a filter. This may be the little cross we find in the Biosun candles or it may be a tapered end, anything that partially obstructs the free flow of the air inside the candle. When cutting the candles above any sort of filter we have to ...
By Tony Perry, Los Angeles Times, January 22, 2008. The meeting between the Marines and the power brokers of this border region began with pleasantries, an exchange of gifts, and the drinking of small cups of tea, very hot and very sweet.. But within a few minutes the subject turned to one of crucial importance to both sides: the possible rise of militias among Sunni tribes who feel disrespected and shut out of the mild economic upturn the region is enjoying.. The power brokers - the mayor, the sheiks, and the local Iraqi army general - are from the Albu Mahal tribe, the most powerful in the region.. The Mahals were the first of the tribes to join with the U.S. in fighting the insurgency while lesser tribes stayed neutral or assisted the insurgents.. Now that the insurgency has been largely suppressed, Mahal leaders feel it is their right to share in the benefits of peace, such as the flourishing downtown market in Husaybah and the recently opened port of entry that allows a free flow of goods ...

Shared these thoughts and a few more with a reporter from CNN a few moments ago: The arrest of Henry Louis Gates sends a chilling message to the scholars, writers, activists, and artists who work so hard to keep a free flow of information. It seems eerily ironic Mr. Gates was returning from China, where surveillance is so high and freedom of speech and ideas so curtailed. To see the mugshot of Skip was a blow to all of us who feel some sense of safety based on our work to try to mend all of these broken fences in America--to make ourselves into people who refuse to be limited by race and class and gender and everything else. We do this work every day, and it is work, just like any other. To end up, at the end of the day, treated like a criminal, unjustly stripped of our accomplishments and contributions even if only for a moment, is profoundly disturbing. We must ask ourselves what it means, and to allow ourselves to face various scenarios regarding power and freedom and how these will ...
A common issue with tube feeding is snagging: door knobs, chairs, and otuer humans have been my top three culprits for sometimes a rather rough tug. And no. It does not feel very good.. There are a lot of people who use the button style tubes as either their G and/or J tubes because of the tube being low-profle, but in my experience, the button style tubes are superior in design and function. Even when accessed, these tubes arent as bulky and easier to conceal (which is good for those of us on continuous feeds). The extension tubing used to access the tubes are disposable, which is beneficial in respects to keeping things as sanitary as possible and in best functioning order. Extension tubing also has a clamp so there is only free flow of content when one is too absent minded to forget to squeeze the clamp shut and pump alarms are also as easy to fix as releasing the clamp (those are moments when you shake your head and say out loud to yourself Really?).. Here is another benefit of the ...

I could not be mad or frustrated with him. He was just doing his job and the customer is not always right. Still, I wondered why this process was necessary and tried to process why there was a $10 service fee for cancelling the flight. The reality was, I needed to get home.. A one-way ticket when you have intentions of returning home can be a challenge, although the free flow of having no set plans has its perks of adrenaline. The other week, I was on a budget search for a plane ticket from Buenos Aires, Argentina, to Toronto, Canada. I could philosophize about whether my return was meant to be, but I knew I had to make it home as I had made a promise to a friend to return for her wedding and funds were running out.. So, I started looking for flights and a couple of weeks ago, I found one. I booked it. I wiped my hands of any stress. Until, that is, the e-mail came a week ago saying that it had been cancelled. Trying to get home became an enduring task mixed in with a little stress.. One night ...
