Few association mapping studies have simultaneously accounted for population structure, genotype by environment interaction (GEI), and spatial variation. In this sugarcane association mapping study we tested models accounting for these factors and identified the impact that each model component had on the list of markers declared as being significantly associated with traits. About 480 genotype...

The main objective of this paper centers on reviewing the evolution of Decision Support System’s (DSS) architectures, particularly as they apply to natural resources. Today it is difficult to conceive the existence of a rural planning automated system that doesn't include spatial analysis functionality and that does not consider the integrated use of different analytical modules. This wider ran...

Based on the soft sensor techniques, five external factors that affect the cane sugar crystallization process are used as auxiliary variables, i.e., the syrup Brix and temperature, vacuum, steam pressure and feed flow, while the sucrose supersaturation is considered as the key variable. Then a soft sensor method for the sucrose supersaturation is developed based on kernel partial least squares....

The results of two field trials to determine the effect of ratoon stunting disease on the growth and yield of some widely grown and newly released sugarcane varieties are described. In the plant crop of a trial grown under full irrigation, the greatest reductions in yields of cane and sugar among six varieties, approximately 15%, occurred in N 14 and NC0376. In the first ratoon, the greatest re...

Increasing irrigation levels from 37% to 84% of Class "A" Pan evaporation produced a linear increase in cane yield from 65 to 146 tonslha. The response with burnt cane was greater due to more severe moisture stress, and there was also an increase in cane yield between 84% and 100% Pan which was absent in trashed cane. Maximum sucrose content, as well as brix, purity and recoverable sugar % cane...

The agricultural economy of the coastal zone of Queensland and adjacent areas of New South Wales is dominated by sugar production designed for inter-state and overseas export destinations. The modern bulk-cargo terminals which provide shipment facilities at six Queensland sugarports constitute a critical element in a complex system of cultivation, processing, transport and marketing which is cl...

We present a case of acute hepatitis caused by dengue virus, with a significant increase in aspartate transferase and alanine transferase levels in a chronic hepatitis patient attended at the Cane Sugar Planters Hospital of Campos dos Goytacazes, RJ.

This paper analyses the technological advances which have taken place on both the field and factory sides of sugar production in the past 30 years. It focuses on three leading sugar producers; Australia, France and South Africa. It finds that the greatest technological gains have been made in the beet sector (France). All three countries have improved the efficiency of their factory operations ...
