Commercial vegetative propagation of oricultural crops requires the segregation of plant cuttings into categories based on size. The cuttings however must be graded when they are planted ("stuck"), at which time the grade of a cutting is not easy to determine. This paper reports on a system that learns to classify cuttings from being shown examples of images of cuttings that have been graded by...

1 The Affect of Spatial Resolution on Measurement of Vegetation Cover in Three Mojave Desert Shrub Communities Thomas D. Frank and Scott A. Tweddale Abstract Coarse resolution remotely sensed imagery (20-30m) has lacked sufficient spatial resolution to accurately measure total vegetative cover in arid environments where vegetation cover is relatively low. New and emerging satellite and airborne...

Grain yield and yield components of winter wheat were recorded during 2-year field trials in Southern Bavaria, Germany. The impact of single ear sink size on the efficiency of grain production was studied in plants differing in single ear weight. While total grain yield showed only slight differences between N fertiliser treatments, significant variations were detected in harvest index and N ha...

Streams of the Flint River Basin (FRB) remain as viable habitat for many freshwater species and harbor some of the most diverse mussel assemblages in the Southeast. However, land use changes, hydrologic alterations, and declines in native fish species have adversely affected mussel diversity and abundance throughout the region. Protection of rare and sensitive mussels requires the development o...

Phosphorus adsorption by a water treatment residual was tested through Langmuir and linear sorption isotherms and applied in the Soil and Water Assessment Tool (SWAT). This study uses laboratory and greenhouse experimental Phosphorus data to evaluate the performance of a modified version of SWAT for high P concentration simulation development. A combination of vegetative filter strips (VFS) and...

This work was carried out during the two seasons of 2008 and 2009 aiming to study the effect of different levels of cattle manure and biofertilizers (phosphorein and/or nitrobein) as well as their interactions treatments on the growth, sepals, seed yields and some chemical constituents of roselle plants. The obtained results show that all levels of cattle manure and inoculated biofertilizers an...

Soil environmental quality is the capacity of a soil to function, within ecosystem and land use boundaries, to sustain biological productivity, maintain environmental quality, and promote plant, animal and human health'. In the long-term, vegetative rehabilitation of mining wastes aims at, as far as possible, the proper ecological integration of the reclaimed area into the surrounding landscape...

The present study is focused on the improvement of Bacillus licheniformis through random mutagenesis to obtain mutant having enhanced production of bacitracin. Many isolates of Bacillus licheniformis were isolated and the isolate GP-40 produced maximum bacitracin production (16±0.72 IU/mL). Treatment of Bacillus licheniformis GP-40 with ultraviolet (UV) radiations increased bacitracin productio...

Commercial vegetative propagation of floricultural crops requires the segregation of plant cuttings into categories based on size. The cuttings however must be graded when they are planted (" stuck "), at which time the grade of a cutting is not easy to determine. This report describes a system that learns to classify cuttings from being shown examples of images of cuttings that have been grade...

Under specific conditions—later called the 'R.K.-conditions'—bacterial nucleoids can be fixed with OsO4 so as to contain fine fibrillar material when viewed on thin sections. Under other conditions, and —as was shown later —with aldehydes, aggregations occur. Those induced with EDTA (formerly under the trade name 'versene'} allow a practical aggregation test. The pool of vegetative ( = replicat...
