Since their classification already provides the formation of new stabilizing bone (sclerosis, increased valuable information about the aggressive nature to be thickness). In the case of faster growth the bone does not expected, without any knowledge of the histology, it will have time to react with new bone formation, and osteolysis be described briefly below. If bone breakdown predominates, osteolysis results, whereas ex- Periosteal reactions cessive bone formation results in osteosclerosis. The turn- Tumors can produce widely differing periosteal reactions over processes differ depending on whether cancellous or (⊡ Table 4. But these are not visible on the x-ray until they 4 The above statements indicate that the site is very important for the appearance of the tumor on the x-ray. While the degree of loading influences the reaction to tu- mor growth, the appearance on the x-ray is most strongly affected by the rate of tumor growth. Destruction pattern in compact and cancellous bone according to Lodwick and Wilson The classification system involves three basic patterns of bone destruction: ▬ I: geographic (map-like), primarily involving the can- cellous bone, ▬ II: mixed forms (geographic and moth-eaten/perme- ative), ▬ III: moth-eaten lesion, in compact and cancellous bone, or permeative destruction in the compact bone only. Various grades are differentiated according to the reac- tion of the compact bone and the penetration of the cortex in each case (⊡ Table 4.
For example purchase extra super levitra 100mg without a prescription, in the sentence The study was continued for a number of years, the underlined word group is the predicate because it tells us what happened to the study. The word or phrase that is usually a noun or an adjective and that completes the predicate and/or describes the subject is called the complement. In the above sentence, the phrase for a number of years is the complement. The complement is often a single word such as in the sentence The 222 Grammar man was embarrassed where was embarrassed is the predicate and embarrassed is the complement. To complicate matters even further, verbs can take an “active” or a “passive” form. Fortunately, computer grammar checkers often alert us if we use a passive verb form. One way to recognise the passive form without relying on computer alerts is that the verb is usually a cluster of several words and the subject often follows the verb rather than leading the sentence. For example, you can write that People are considered to be at higher risk for having heart disease if they are obese or that Obesity is a risk factor for heart disease. In the first sentence, the subject is people and there is a passive verb cluster are considered to be. However, the second sentence correctly has the subject obesity at the beginning and uses an active verb is. The use of active verbs is a sure way to improve the readability of scientific writing. Some examples of changing long, passive verb constructions into short, active ones are shown in Box 9. In the first example, the verb form has been shown to be is certainly the passive voice and can be easily replaced with is or any other short form of the verb to be. This example also has another problem in that it is the children with attention deficit disorder who have the problems, not the disease itself. It is important to be on the look out for faulty sentence constructions such as this.
