As the number and size of computer corpora grow, linguistic researchers are increasingly using them to study changes in language over time. Comparing usage at one point in time with usage at a later or an earlier period seems a stunningly simple and Sausurreanly impeccable method of studying language change. Needless to say the reality is rather different. This paper identifies some of the meth...

Introduction Substitution tilings have been discussed now for at least twenty-five years, initially motivated by the construction of hierarchical non-periodic structures in the Euclidean plane [?, ?, ?, ?]. Aperiodic sets of tiles were often created by forcing these structures to emerge. Recently, this line was more or less completed, with the demonstration that (essentially) every substitution...

biosignature_movie_1.mpg (987 KB) An MPEG format movie showing the development of the MAB in Avida as described in Chapter 2. This movie shows the relative abundances of 28 Avida instructions in a single typical evolutionary run. This run was seeded with the standard progenitor (listed in Table 2.1) and run for 200,000 updates with copy mutation probability $\mu$=0.01 randomizing mutations per ...

When I began my career in dentistry twenty-five years ago, the "fee-for-service" practice was by far the most common approach for delivery of care. Time was not taken to define individuality and purpose, and outside factors such as insurance did not attempt to dictate the direction we took toward a treatment plan. Marketing was not mentioned and practice management as we know it was just beginn...

Solitary confinement is a frequently used penal tool in all fifty states against all types of offenders. However, since its development in the 1800s, solitary confinement has been found to have damaging psychological effects. Juvenile inmates in particular suffer the greatest psychological damage from solitary confinement because their brains are still in a developmental state. This has led man...

objective: this field experiment was laid out in order to study on effect of nano and bio fertilizers on yield and yield components of tomato (lycopersicone sculentum l.) during the growing seasons 2013- 2014. methods: the experiment was laid out in a factorial based on randomized block design with three replications. treatments were k nanofertilizer in five levels such as (0, 100, 200, 300 and...

this paper explored the multiple relationships between intellectual capital (ic) and knowledge management (km) in an iranian university. for intellectual capital, three components were studied including: relational capital, structural capital and human capital. for knowledge management, five processes were considered, namely creation, acquisition, codification, sharing and application. the rela...

The effects of mandarin scions on peel components and juice quality parameters were investigated in this study. Peel flavor components were extracted by using cold-press and eluted by using n-hexane. Then all analyzed by GC-FID and GC-MS. Total soluble solids, total acids, pH value, ascorbic acid as well as density and ash were determined in juice obtained from mandarin scions. Twenty-seven, Tw...

the effects of rootstock on the volatile flavour components of page mandarin juice and peel were investigated in this study. juice flavour components were extracted by using poly dimethyl silaxane  membranes( pdms ) and eluted by pentane dichloromethane and then analyzed by gc-fid and gc-ms. peel flavour components were extracted by using cold-press and eluted by using n-hexane and then analyze...

exiting diversity is the basis of selection in plant breeding programs. diversity in morphological traits is studied by different methods of multivariate analysis. this study was conducted to estimate the genetical diversity of new corn hybrids based on the morphological traits. in this study, 40 new grain and forage corn hybrids with five commercial varieties as control treatments were planted...
