Concerted action

All nonconformities are caused, all causes within your control can be avoided - all that is needed is concerted action to prevent recurrence. There are three types of corrective action product-related, process-related, and system-related. Product-related nonconformities can be either internal or external, as addressed previously, and you will have nonconformity reports to analyze. Process-related nonconformities may arise out of a product nonconformity but if you expect something less than 100% yield from the process, the reject items may not be considered nonconformities. They may be regarded as scrap. By analyzing the process you can find the cause of low yield and improve... [Pg.456]

In vitro, SNARE-complex formation is irreversible. Disassembly requires the concerted action of the chaperone-like ATPase NSF and SNAPs. [Pg.1146]

The members of Group 1 are called the alkali metals. The chemical properties of these elements are unique and strikingly similar from one to another. Nevertheless, there are differences, and the subtlety of some of these differences is the basis of the most subtle property of matter consciousness. Our thinking, which relies on the transmission of signals along neurons, is achieved by the concerted action of sodium and potassium ions and their carefully regulated migration across membranes. So, even to learn about sodium and potassium, we have to make use of them in our brains. [Pg.707]

The primary interaction of singlet oxygen, produced by energy transfer from the excited sensitizer, with the diene can give rise to an exciplet that then collapses to peroxide, to a 1,4-biradical or to a 1,4-zwitterion alternatively, the adduct is the result of a concerted action without the involvement of an intermediate. Detailed kinetic Diels-Alder investigations of singlet oxygen and furans indicate that the reactions proceed concertedly but are asynchronous with the involvement of an exciplex as the primary reaction intermediate [63]. [Pg.169]

Figure 3. Mitochondrial fatty acid oxidation. Long-chain fatty acids are converted to their CoA-esters as described in the text, and their fatty-acyl-groups transferred to CoA in the matrix by the concerted action of CPT 1, the acylcarnitine/carnitine exchange carrier and CPT (A) as described in the text. Medium-chain and short-chain fatty acids (Cg or less) diffuse directly into the matrix where they are converted to their acyl-CoA esters by a acyl-CoA synthase. The mechanism of p-oxidation is shown below (B). Each cycle of P-oxidation removes -CH2-CH2- as an acetyl unit until the fatty acids are completely converted to acetyl-CoA. The enzymes catalyzing each stage of P-oxidation have different but overlapping specificities. In muscle mitochondria, most acetyl-CoA is oxidized to CO2 and H2O by the citrate cycle (Figure 4) some is converted to acylcamitine by carnitine acetyltransferase (associated with the inner face of the inner membrane) and exported from the matrix. Some acetyl-CoA (if in excess) is hydrolyzed to acetate and CoASH by acetyl-CoA hydrolase in the matrix. Enzymes ... Figure 3. Mitochondrial fatty acid oxidation.

Although the crystal structure of CODH or CODH/ACS has not yet been solved, a great deal of work has been done on these enzymes and plausible catalytic mechanisms have been proposed. Concerted action between the Ni ion and one of the Fe centers of a 4Fe-4S cluster are thought to elicit the formation of CO2 from CO. But perhaps the most extraordinary reaction is the one catalyzed by Cluster A the insertion of CO to a Ni-CHs complex. Through the two reactions catalyzed by CODH/ACS, the highly toxic, CO is not only removed, but is used as a source of carbon and electrons. [Pg.327]

Interestingly, post integration latency in microglial cells seems to be the result of the concerted action of both HDACs as well as HMTs on core histone H3 in nuc-1 (Marban et al. 2007). COUP-TF interacting protein 2 (CTIP2), a transcriptional repressor interacts with HDACl and HDAC2 via its N-terminus to repress... [Pg.102]

HPAEC analyses were carried out to determine the oligomeric products released from various pectic substrates after depolymerization by the PL isoenzymes. Action pattern analyses for the concerted action of PL isoenzymes utilized 68% esterified pectin as substrate. One-ml reaction mixtures in a buffer system as detailed in section 2.2. comprising 0.5% (w/v) substrate and 5 U of enzyme were incubated for 30 s to 18 h, and then thermoinactivated. Samples of 750 pi were applied to a Carbopac PA-1 (Dionex) column before the carbohydrates were eluted over a period of 70 min using a gradient of 0.2 M KOH, 0.05 M K-acetate to 0.2 M KOH, 0.7 M K-acetate. Detection employed a Pulsed Electrochemical Detector (PED, Dionex) in the integrated amperometry mode according to the manufacturer s recommendations. [Pg.285]

Ionization may be used to counteract disregulation of pH levels (which is maintained through the concerted action of Na /H antiporters, CL/HCO3" exchangers, and other channels and/or transporters that exist within the plasma membrane of eucaryotic cells [32,100,101]). Indeed, it has been shown that iono-phores (such as nigericin [102]) can lower the intracellular pH, while weak acids (such as propionic acid) can promote acidification. Likewise, nonsteroidal anti-... [Pg.729]

Many policies and practices have been adopted by European countries for the management of contaminated sites. Information about the various national polices, the technical approaches for risk assessment, and the progress of rehabilitation activities in Europe has been compiled in the framework of two European networks—CARACS (Concerted Action for Risk Assessment for Contaminated Sites) and CLARINET (Contaminated Land Rehabilitation Network for Environmental Technologies)—which were funded by the European Commission. A detailed description of European national policies can be found in relevant publications2 3 and in the CLARINET website (http //www.clarinet.at). [Pg.520]

The above three examples illustrate how a species-specific pheromone blend is produced by the concerted action of desaturases, chain shortening enzymes, a reductase, and an acetyltransferase. The specificity inherent in certain enzymes in the pathway produces the final blend of pheromone components. [Pg.112]

Even complicated, charged macromolecules like proteins can be succesfully displaced. As an example we give in Figure 6 the displacement isotherm for human plasma albumin from silica by morpholine (21). Of course, in this case where charge effects and a variety of segment/surface interactions play a role, our simple Equation 5 does not apply. Nevertheless, for practical work it is important to realize that most macromolecules, often thought to be irreversibly adsorbed, can be removed completely from the adsorbent surface by the concerted action of a large number of small molecules. [Pg.64]

Scientific knowledge in these key areas was improved through the work of a concerted action, organized within the framework of the fourth EU-Framework program. In this action, 15 research centers and universities of 11 European counties, Israel, Poland, and Canada participated, and the project was funded by the Directorate General XII of the Commission of European Communities under Research Grant FAIR-CT96-1118. [Pg.177]

The complexity and vastness of the scientific field that has been reviewed in this chapter bring forth, as a natural consequence, the parallel need for further in-depth studies into some key research areas. Knowledge of the process, as a unit operation, has jumped forward due to the fruitful work of the EU-FAIR Concerted Action CT96-1118 improvement of overall food quality by application of osmotic treatments in conventional and new processes and could already support the application of the technique at the industrial level as a prestep in innovative combined processes. The decisive challenge for a completely successful process control and optimization has to be focused on the following problematic aspects. [Pg.224]

The COST Project 68 lasted for 2 years and was considered fruitful for scientific progress in the field there were seen to be also considerable advantages to the 13 individual countries in sharing research in this project . It was not surprising therefore when a decision was made by the European Commission in 1976 to continue this type of co-operation in the form of a Concerted Action designated COST 68 bis . [Pg.3]

Under COST 68 bis, five Working Parties were established to co-ordinate the various areas of research. As a Concerted Action , no direct funding was available from the European Commission to finance research projects on sewage sludge, each country being expected to contribute its own publicly-funded projects to the common pool . [Pg.3]
