Only natural dyes were known until the nineteenth century. By trial and error and probably also by chance, humans learned to extract and use a large variety of dyes of vegetable and animal origin. Dyes were extracted from the roots, trunk bark, and branches of trees, the stems, leaves, flowers, and fruits of plants, the bodies of insects and mollusks, and the eggs of insects. All the dyes obtained from natural sources are rather impure, and hence the accurate reproducibility of colors was almost impossible during antiquity. Still, many of the dyes and dyeing techniques used in antiquity were highly developed and remained in use until the discovery of the synthetic dyes in the middle of the nineteenth century (Colombo 1995 Robinson 1969).

Consider the analysis of the leaves on a tree for pesticide residue. The tree grower wants to know whether the level of pesticide residue on the leaves indicates that the tree needs another pesticide application. Once again, the analyst must consider all parts of the tree that might be different. Leaves at the top, in the middle, and at the bottom should be sampled (one can imagine differences in application rates at the different heights) leaves on the outside and leaves close to the trunk should be sampled and perhaps there would also be a difference between the shady side and sunny side of the tree. All leaf samples are then combined for a composite sample. 

In the middle range of styrene concentrations, a compromise is attained where there is sufficient styrene to scavenge all excess methanol radicals not involved in activation of the trunk polymer, yet an excess of monomer remains for grafting by the charge-transfer mechanism proposed by Dilli and Garnett (12) originally for copolymerisation to cellulose (4) and subsequently extended to wool (3), polyolefin (2,5) and PVC (13) systems. The data in Table V are consistent with this interpretation. 

Mitochondrial disorders are not commonly regarded as causes of malformations. Facial features included round face, high forehead, small nose, and long flat philtrum, reminiscent of the fetal alcohol syndrome. Limb and trunk involvements included short hands, brachydactyly, hypoplasia of the distal and middle phalanges, hypoplastic nails, and the VACTERL [vertebral anomalies, anal atresia, cardiovascular anomalies, tracheoesophageal fistula, esophageal atresia, renal (kidney) and/or radial anomalies, and preaxial limb anomalies (in front of or above the central axis of the limb)] association [50]. 

A 24-year-old man with acute malaise and fever had a pruritic rash with multiple erythematous circumscribed weals on the trunk, arms, legs, neck, and scalp. He admitted to using intranasal cocaine 6 months, 4 days, and 1 day before the onset of the symptoms. His temperature was 39° C. His erythrocyte sedimentation rate was 80 mm in the first hour, C-reactive protein was 283 mg/1 (reference range below 10), and the white blood cell count was 12.4 x 109/1 with 89% neutrophils. A biopsy of an urticarial lesion showed a perivascular inflammatory infiltrate in the upper and middle dermis. Bed rest, oral prednisone, oral hydroxyzine, and topical polidocanol led to improvement within 24 hours. 

The middle cerebral artery enters the Sylvian fissure and divides into two to four branches, which supply the lateral parts of the cerebral hemisphere. From its main trunk, a medial and lateral group of tiny lenticulostriate arteries and arterioles pass upwards to penetrate the base of the brain and supply the basal ganglia and internal capsule (Marinkovic et al. 1985). Some of these small penetrating vessels extend up into the white matter of the corona radiata in the centrum semiovale towards the small medullary perforating branches of the cortical arteries coming down from above. 

Partial anterior circulation infarcts (Fig. 9.4) are caused by occlusion of a branch of the middle cerebral artery, or rarely the trunk of the anterior cerebral artery. They are usually... 

The principle of the sandwich system is that a strip about 50 cm wide on either side of the row of trees, outside the area of the trunks, is hoed, while at the same time low ground cover is grown on a 35-50 cm wide strip in the middle of the row, without mulching. The total volume of soil without competition from vegetation, per tree, thus remains just as large as if the whole area were hoed, or it can he varied as required. 

Folded burlap strips can also trap pests as they travel up the trunk. Cut a 20" wide strip of burlap fabric and wrap it around the trunk. Tie it to the tree with a cord in the middle of the strip, and let the top half fold down over the bottom, forming a pocket that will trap pests. You can apply a solution of parasitic nematodes to the burlap for added control. Seal bands at the edges with a layer of sticky ointment to prevent other pests from crawling under them. 

PC has two principal layers of pyramidal neurons, layers II and III, corresponding to superficial and deep pyramidal cells (Fig. 26). A third morphologically distinct subtype, the middle pyramidal cell has also been suggested, but is supported by only limited evidence (Martinez et al. 1987). Pyramidal neurons have several characteristic features and are similar to those in other cortical regions and the hippocampus (1) A primary apical dendritic trunk that extends radially towards the pial surface and arborizes into numerous smaller branches that ramify in layer la and Ib (Haberly, 1983 Martinez et al. 1987). Some of these branches turn and run parallel to the pial surface for short distances. (2) A large number of relatively thin secondary or basal dendrites that emerge from the soma and extend several hundred microns into deeper parts of PC. Both the apical and basal dendritic tree are heavily invested with spines and varicosities. (3) A myelinated axon that typically extends deep to the soma terminates on other local pyramidal cells and interneurons (see below). ...

As far back as the middle of the 20th century trunk pipelines were protected from corrosion mainly by bitumen and paper and operated reliably with such insulation for 20 to 30 years. Modern systems of protecting pipelines are much more complex and expensive (see Sect. 3.5.3) but their useful operating life has fallen. The main reason is contamination of the environment caused by man, composed of a number of factors, namely ...
