Mossbauer spectroscopy is an analytical technique that, in archaeological ceramic studies, provides information on the condition and characteristics of the compounds of iron in pottery. Using the technique makes it possible to determine the relative amounts of the different (ferrous and ferric) ions of iron and hence to ascertain the firing conditions of the pottery at the time it was made. The technique involves irradiating a sample of pottery with gamma rays and then assessing the amount of radiation absorbed by the nuclei of the ions of iron within the pottery (Feathers et al. 1998 Bearat and Pradell 1997). 

Dust from animal houses consists mainly of organic matter (23). The preferred technique for investigating both the material composition of the dust and feed stuff is the WEENDER Analysis Technique (24). Table II shows the composition of dust from pig and hen houses compared to the feed fed. The differences in the protein content between dust and feed support the opinion that an important part of the dust originates from feathers, hairs, and skin cells of the animals. 

Environmental problems often benefit from the application of screening analysis. Data obtained from the analysis of whooping crane feathers are presented in Table X. (The attention to whooping cranes results from a decline in the flock population over the past few years.) In this instance, the ICAP was able to provide screening data for limited amounts of sample, as only one wing feather per bird was available. Common analytical techniques would not have been able to provide such a broad spectrum of elemental analyses as cost effectively as the ICAP approach. 

Sometimes the valve disk does not reseat properly, but continues to discharge a small quantity of fluid. This is known as feathering of the valve, and it can be caused by damage to the seal from particulate matter suspended in the relieving fluid. It can also be due to balance of those forces that control the functioning of the valve, which can be checked using the techniques described in the next section.

The use of chemiluminescence technique has expanded to others natural polymers. Recently, Millington et al. reported studies on polymers such as the fibrous proteins wool and feather keratin, silk fibroin, and reconstituted collagen from bovine skin, which revealed new information about their degradation [81]. The potential of CL to analyze the effectiveness of treatments to protect the polymer during processing could contribute to diminish the loss of properties of the types of polymers widely used in textile industry. 

The method of residuals is a commonly employed technique for resolving a curve into various exponential terms. This method is also known as feathering or curve stripping (see p.l02). The curve from the observed data and that for the extrapolated line are depicted in Fig. 13.11. Table 13.2 gives the headings for the data that can be extracted from the figure. 

It has been found that catching the chickens at night when they are normally asleep poses the least disturbance when they are caught using conventional techniques. Even so, a lot of feathers still fly. 

Hydrojetting is probably the concrete removal technique of choice for minimal damage, cleaning of rebars and removal to required depth. In all cases the edges of removed areas must be square to the surface with no feathering that would be difficult to fill with reasonably sized aggregates (Figure 6.2). 

In this study, we present the morphology of the different parts of the feather and the chemical technique used to convert poultry feathers to powders or fibers or wool. Then, a suitable molding technique was performed in order to produce highly filled composite samples. The concentration... 

The chemical technique used, to convert the raw poultry feathers into useful products, was developed in our laboratory. The process of the transformation is illustrated in the figure 1. The concentration, of the chemical solutions used, is function of the nature and the desired product. Hence, according to the application, the poultry feathers may be converted into useful materials in the form of powder, fibers or wool.
