Experimental site

Table 1 gives the half-lives, Dt50 and Dt90/ for the results from the three experimental sites. Table 2 contains the values for the amount of residue found at 0 day after the fourth application. 

Although the use of enclosures is conceptually the simplest approach, some particular problems arise in their use in studies of NH3 loss. These are associated with the chemical reactivity of the gas, particularly its reactivity with water, and to the strong influence of environmental factors on the volatilization process (11). Matching conditions within the enclosure to those prevailing outside is a difficult task and much of the data obtained using enclosures is open to question. However, the problems associated with enclosures can be overcome if the air speed through the enclosure is controllable to within the same range as that of wind speed at the experimental site (9, 12). 

The results obtained were partially reported elsewhere (4) and they are quite similar to those obtained at other experimental sites. Results of long term performance, some of them approaching 10,000 hours are shown in Fig. 3 and Fig. 4. As can be seen in Fig. 3 the initial productivity values for all membranes were better than the specified nominal values and continued to be better than predicted. The results shown in Fig. 4 indicated that the normalized rejection of the membranes tested, except for one of the hollow fiber membranes was better or within the limits specified by the membrane producers. One of the membranes that showed an initially low rejection was successfully restored to the nominal value after treatment as recommended by the manufacturer. 

These waste simulation trials based on laboratory column experiments still needed to be validated using a field approach. Two field leaching tests were thus built on an experimental site (CERED, Vernon, France) to simulate real conditions of a waste deposit site receiving rain or run-off water (Perrodin et al., 2002). The first...

A series of experiments were set up in West Yorkshire, U.K., to test the relationships among the decomposition of buried hair, textiles, metal, and cadavers (pig) under a range of conditions relevant to regional depositional environments (Holland 2000 Wilson et al. 2007). Replicated cadaver and control graves (i.e., graves with experimental materials but without cadavers) were dug and exhumed after 6,12, and 24 months. Three experimental sites were used pasture, moorland, and woodland. These were chosen to complement each other in terms of altitude, soils, and drainage (Wilson 2002). 

In this work we report organic and elemental carbon data, l C content and 13c/12c isotopic ratios for samples obtained in a larger set of measurements in the POLTERCAIST (POLlutant-TERpene CAnopy Interaction STudy) taken at the Walker Branch experimental site, Oak Ridge National Laboratory, Oak Ridge, TN, during a summer period (July, 1983) and a late winter period (March,...

A 5-acre field, belonging to the Arkansas Southeastern Branch Experiment Station at Kelso, Ark., was chosen as the experimental site. The relationship of the site to its environs is shown in Figure 2. Irrigation water was introduced from a head ditch on the north side of the plot and flowed through the %-mile furrows to a drainage ditch, which was sampled as it left the field. The ditch ran % mile until the water was held for reuse by a check dam. It was estimated that the water was diluted 20-fold at the dam site. The dam held the drainage of 800 acres of cultivated land.

The nature of OA interaction with SC lipids in vivo was of significant interest, particularly in light of the IR results above. Reflectance IR spectroscopy in conjunction with the use of a deuterated probe once again proved to be a valuable approach for the noninvasive evaluation of this enhancer in humans [153]. Prior to treatment, test sites on the inner ventral forearm of volunteers were cleansed with water, after which the subject remained at constant temperature and relative humidity, while three pretreatment spectra were collected. The experimental site on one arm was treated with a 5% v/v solution of perdeuterated oleic acid ( H-OA) in ethanol, while the control site, on the contralateral arm, was treated with ethanol alone. Both formulations were applied under occlusion for 16 hours posttreatment, the sites were swabbed clean with ethanol and then air-exposed for 2 hours to allow the occluded skin to dry. An ATR-IR spectmm of the dosed site was then obtained. This site was then tape stripped once and a second spectral examination was made. This sequential tape stripping and spectral acquisition was repeated -20 times in order to obtain an incremental spectral profile as a function of SC depth (defined by the cumulative weight of SC removed with tape stripping). IR spectra thus collected yielded the following information (a) the distribution... 

We used principal component analysis to identify correlated motions in different forms of hPNP, namely, its apo and complexed forms, and assess whether they facilitate the 241-265 loop rearrangement prior to the subsequent phosphorolysis reaction. We compared the principal components for the apo and complexed hPNP simulations, and examined the different correlated motions for each form of the enzyme, comparing directly to the crystallographic B-factors. Finally, via experimental site-directed mutagenesis, several residues implicated in the correlated motion were mutated, and the kinetic constants kcat and KM (fingerprints of catalytic efficiency), were measured to weigh the impact of these residues in the phosphorolytic efficiency. 

Water samples from rural residences close to the experimental sites were also analyzed. Three shallow domestic wells contaminated by aldicarb residues above the suggested no adverse response level of 10 ppb were deepened to examine whether the water quality would be improved. 

The demonstration plot of the experimental site should be constructed to evaluate the effectiveness of phytoremediation. The field activities consist of site mobilization, plot layout an construction, and soil sampling combined with other agricultural practices designed secifically for phytoremediation and adapted for the conditions present at the site. The activities has to be conducted in accodance with the personal protective equipment, level of protection, action levels and other health and safety practices, i.e. hazard analysis general safety reccomendations evaluation of the mechanical, electrical, fire hazards, gas and power lines, heat stress, noise, chemical hazards. 

The treatment plots of the two experimental sites at the Kremikovtzi Steel Works were situated between ajacent industrial biuldings and were with dimentions 30 x 20 and 40 x 10 m. Water supply for each site was ensured through locally-mounted hydrants. The irrigation of the experimental sites is important for normal plant growth and high biomass production and is especially critical in dry summer climates, like the Sofia region.

These tests were carried out during June and July 1973, and the experimental site will be further observed in collaboration with the Bordeaux Laboratory of the Highway Administration. 

This experimental site is set up in a tunnel system (see Figure 1) that branches off from a main access tunnel towards the KWO (Kraftwerke Oberhasli AG) underground power station. The GTS tunnel system comprises a laboratory tunnel with a total length of almost 1,000 m plus a central building that houses all the operating facilities (Ortuno, 2000). 

Calibration of the code with the T-H-M experiment performed at the 550 m-Level gallery at the experimental site, illustrated in Figure 1. This step is considered as crucial in building confidence in the codes capabilities to take into account the main physical processes.
