The histological findings were correlated with regard to the age, sex and habits of these individuals and led to the following observations: 1. The squamous epithelium was found to line the laryngeal mucosa in other sites beyond the vocal cords and regardless of the age and sex. 2. Metaplasia and dysplasia of the laryngeal epithelium appear to develop progressively on growing. These lesions are mainly extended to the vocal cords and to the laryngeal surface of the epiglottis in individuals who live in large, crowded cities with high atmospheric pollution as well as in heavy smokers. Contrary to the men, the women show a reduced tendency towards the development of such lesions on the laryngeal epithelium. 3.

The clinical picture is characterized by a slow and gradual emergence of facial assymetric or exophathalmos. Histologically there is a variety of form. The treatment is largely a remodeling osteotomy. The writers effectively applied on all three cases a radial removal of the lesion.

The primary localisation of the tumor in the first case was thought to be near the foreamen lacerum with large areas of bone destruction in the base of the skull. Moreover the internal carotid artery was trophic and thinwalled. In the second patient the onset of the disease must have taken place in childhood as a chronic otitis media. Also in this case the tumor was not diagnosed until it reached a considerable size. The primary localisation was the nervus petrosus superficialis major. In the third patient the neurinoma was located in the facial nerve between the two lobes of the parotid gland. In the fourth case a pedunculated neurinoma of the epipharynx was found. Symptomatology, treatment and differential diagnosis of the Schwannoma are discussed.

Our framework enables smooth scaling (i.e., resizing) of the on-chip caches targeting both performance and power efficiency. In contrast to previous approaches, the resizing decisions in our framework are not tainted by transient events (e.g., misses) that are due to downsizing avoiding at the same time swinging the cache size due to trial-and-error resizing decisions. This minimizes both execution time penalty induced by resizing as well as the effective cache size. Furthermore, an inherent property of our approach is that the actual invalidation of the cache blocks and the corresponding write-backs of the dirty blocks are asynchronous to resizing decisions, ensuring a smooth transition from one size to another. This makes it possible to apply our framework even on write-back caches. The proposed mechanism is simple to implement requiring minimal additional hardware. Using cycle-accurate simulations, we evaluate our proposal against previously proposed techniques. In all cases, our experimental results show significant benefits in both power and performance.
