Extramedullary plasmacytomata form an interesting group of tumours, the nature and behaviour of which are still not well understood. The majority of such tumours are situated in the pharynx, upper respiratory tract, and conjunctiva (Hellwig, 1943). Less frequent sites have been the thyroid, intestine, ovary, and kidney. A study of the literature available to us has revealed that so far 18 cases...

The book under review emerged from a curious and provocative episode in a constitutional fiasco. On 8 December 1998, in an “op-ed” article forThe New York Times and in testimony before the House Committee on the Judiciary, Bruce Ackerman, Sterling Professor of Law at Yale Law School, offered a novel argument. If the House were to adopt articles of impeachment against President Bill Clinton, he ...

The integrity of the alpha-sarcin loop in 28 S ribosomal RNA is critical during protein synthesis. The toxins alpha-sarcin, ricin, Shiga toxin, and Shiga-like toxin inhibit protein synthesis in oocytes by attacking specific nucleotides within this loop (Ackerman, E.J., Saxena, S. K., and Ulbrich, N. (1988) J. Biol. Chem. 263, 17076-17083; Saxena, S.K., O'Brien, A.D., and Ackerman, E.J. (1989) J...

We present a method for calculating odometry in three-dimensions for car-like ground vehicles with an Ackerman-like steering model. In our approach we use the information from a single camera to derive the odometry in the plane and fuse it with roll and pitch information derived from an on-board IMU to extend to three-dimensions, thus providing odometric altitude as well as traditional x and y ...

Individual differences in skill acquisition are influenced by several architectural factors. According to Ackerman’s theory, general intelligence, speed of proceduralization and psychomotor speed influence different stages of skill acquisition. The ACT-R cognitive architecture allows for direct testing of this theory by manipulating parameters that correspond to these factors. The present study...

Introduction: Oral verrucous carcinoma (OVC) is a rare malignancy of the oral cavity that was first described by Ackerman. This tumor is a well-differentiated low-grade, slow growing cancer that is locally invasive without metastasis. Ameloblastoma is one of the most common odontogenic tumors, which originates from the odontogenic epithelium. Verrucous carcinoma along with central ambloblastoma...

Physical and virtual K&C analyses are performed to achieve the vehicle dynamics targets by finding optimum variables such as position of hardpoints or stiffnesses bushings. However, appropriate design that meet all aims is challenging. This paper evaluates a hardpoint optimization approach attain suspension characteristic objectives with experiments, neural networks, genetic algorithm, base...
