An effective extraction of the fiberized cane juice has been obtained from a prepared extraction column. Oligosaccharides co~nposed of glucose and fructose were found in both cane juice and in raw sugar. The oligosaccharides found In the juice and raw sugar were probably produced by enzymatic or bacterial reactions occurring in cane which had had a delay of 24 h or Inore between cutting and pro...

The interplay between selection and genetic exchange at a color locus between populations of Timema walking sticks acts as an anti-speciation phenotype. This actively counteracts speciation and offers a general mechanism to explain the porous nature of species boundaries.

uncaned boys. 26 per cent. of the boys studied had been classified as delinquent in police records by a date at which their mean age was 15 years 4 months. Delinquent boys were significantly heavier smokers than non-delinquents, but the difference was not as marked as that between caned and uncaned boys. There was an apparent decline in smoking over a year. This may be due to errors of recall b...

This study was designed to compare selected kinematic components of gait and long cane mechanics between groups of visually impaired travelers. Twenty subjects were placed in Traditional or Modified technique groups according to their long cane traveling technique. Subjects were measured during the following conditions; 1) normal walking (NW), 2) walking while anticipating a simulated drop-off ...

This paper describes preliminary work with radiophosphorus (P-32) undertaken by the author at the S.A.S.A. Experiment Station, Mount Edgecombe. In order to study the root spread of N :Co.376, radiophosphorus in solution was injected into the soil at various distances, positions and depths in relation to the cane row. (Cane planted 3rd October, 1962.) Uptake of this radiophosphorus by the plant ...

A user friendly, computer based program has been developed to estimate the performance and cost of sugarcane combine harvesters and associated infield transport vehicles. The model was originally developed to assess the effect of various field parameters, infield cultural practices and also the number and capacity of infield transport vehicles on harvester output. A costing program was subseque...

The genus Saccharum consists of two wild and four cultivated species. Novel interspersed sequences were isolated from cultivated sugar cane S. officinarum. These sequences were accumulated in all four cultivated species and their wild ancestral species S. robustum, but were not detected in the other wild species S. spontaneum and the relative Erianthus arundinaceus. The species-specific accumul...

Urban development is the most common form of land conversion in the United States. Using a before-after control-impact study design, we investigated the effects of urbanization on larval and adult stages of southern two-lined salamanders (Eurycea cirrigera) and northern dusky salamanders (Desmognathus fuscus). Over 5 years, we estimated changes in occupancy and probabilities of colonization and...

I conduct a cross-country analysis of the human development index (HDI) components, income, life expectancy, literacy and gross enrolment ratios, using Gray and Purser’s 1970-2005 quinquennial database for 111 countries. 1) A descriptive analysis uncovers a complex pattern of divergence and convergence for these components’ evolution. Development is not a smooth process but consists of a series...
