Destructive activities

Seek to divert vanadium to less harmful destructive activity by adding cheap and/or naturally occurring sieves. For these we proposed the term "sacrificial sieves". 

A typical large university has 100 research projects using radioactivity, and the work supported by 40 percent of biomedical research grants, and described in 50 percent of articles in biomedical journals, uses radioactivity. I believe that food preservation by irradiation may be about to take off, providing more wholesome, better-tasting, and better-looking foods that are b oun d to attract public attention. Perhaps people will wonder why the benefits of irradiated food have been denied to them for so long, and come to appreciate the irrational, destructive activities of so-called environmental and consumer advocates.

As destruction activities have increased, the Technical Secretariat is becoming even more active. In 2004, the OPCW hired 19 inspectors (Group D) in four chemical-weapons-related occupational groups, and in 2005 another 9 (Group E) came on board. And, in August 2005, re-... 

Recent work on laboratory catalyst deactivation in the presence of Ni and V by cyclic propylene steaming (CPS) has shown that a number of conditions affect the dehydrogenation activity and zeolite destruction activity of the individual metals. These conditions include find metal oxidation state, overall exposure of the metal to oxidation, the catalyst composition, the total metal concentration and the NiA ratio. Microactivity data, which show dramatic changes in coke and hydrogen production, and surface area results, which show changes in zeolite stability, are presented that illustrate the effect each of these conditions has on the laboratory deactivation of metals. The CPS conditions which are adjustable, namely final metal oxidation state and overall exposure of the metal to oxidation are used as variables which can control the metal deactivation procedure and improve the simulation of commercial catalyst deactivation. In particular, the CPS procedure can be modified to simulate both full combustion and partial combustion regeneration.

Corrosion of concrete by bacteria that oxidize sulfur compounds into sulfuric acid was reported by Parker (1945, 1947) and has been examined more recently by Fjerdingstad (1969). The lowest pH is tolerated by Thiobacillus concretivorus Parker (pH 2.75 + 0.42) and T. thiooxidans Waksman and Joffe (pH 2.35 0.32). Within 100 days of incubation in a T. thiooxidans culture, 60% of a 3.6 g block of concrete were dissolved. Bacterial destructive activity has also been established on buildings and monuments (Krum-... 

The authors suggested that the tissue-destructive activity of the trophoblast is probably plasmin-mediated, though the source of the plasminogen remains unclear relative to PA alone, the plasmin produced by plasminogen activation would provide a tremendous amplification of both the enzymatic activity and the substrate range, in keeping with the extensive tissue destruction observed during implantation.

Chemical weapons stored overseas were collected at Johnston Island, southwest of Hawaii, and destroyed by the Johnston Atoll Chemical Agent Disposal System (JACADS), the first operational chemical demilitarization facility. JACADS began destruction activities in 1990 and completed processing of the 2,031 tons of chemical agent and the associated 412,732 munitions and containers in the overseas stockpile in November 2000 (U.S. Army, 2001a). 

Numerous catalysts have been tested for their tar destructive activity over a broad range of conditions, and recent literature reviews are available on biomass gasification tar destruction and the preparation and characterization of the various catalytic materials used for this purpose [28, 50]. These include commercial Ni catalysts developed specifically for steam reforming, which have found application in biomass gasification tar conversion and as secondary catalysts in separate fixed and fluidized bed reactors [2].

The radicalic mechanism of such a process of destruction activated by the polymeric solutions forced passing through the capillaries has been demonstrated by the introduction of some radicalic acceptors, either in the monofilaments coagulation bath or in the solution of polymer subjected to spinning. 

No oxidation peaks for triclosan were observed in cyclic voltammetry scans in edianol solutions. At all potentials die anodic currents in die presence of triclosan were lower than diose in the blank ethanol solutions. This can be attributed to partial inactivation of die surface by oxidation product films. In extended electrolysis eiqieriments conducted at a current density of S mA/cm nearly conqilete inactivation of the electrode for triclosan destruction was observed by 2 hours ehqised, as shown in Figure 4. However, continuation of die electrolysis at a current density of IS mA/cm was able to partially restore the triclosan destruction activity.
