To produce high-quality broccoli microgreens, suitable light intensity for growth and phytochemical contents of microgreens in an artificial plant factory were studied. Broccoli irradiated under different photosynthetic photon flux density (PPFD): 30, 50, 70 90 ?mol·m?2·s?1 with red: green: blue = 1:1:1 light-emitting diodes (LEDs). The grown 50 had the highest fresh weight, dry moisture conten...

The subject can be broadly classified under two headings: Water Treatment and Combustion. It is not the object of this paper to elaborate the methods of running efficiency tests and their attendant calculations, but rather to discuss the laboratory and factory work of the chemist in this more or less engineering subject. I think we can safely say that the day is past when accidents and expensiv...

The South African Sugar Association Experiment Station, Agricultural Engineering Department conducted a series of semi-mechanised versus fully mechanised harvesting trials on a large commercial estate in Swaziland over the 1998/1999, 2000/2001 and 2001/2002 seasons. During the trials machinery performance was measured, differences in the quality of cane delivered to the factory were determined,...

A dynamic mathematical model of a multiple effect evaporator has been developed for a digital computer using the IBM Continuous Systems Modelling Program. The model will be incorporated in an overall simulation of a cane sugar factory. The mathematical model was derived from material and energy balance equations assuming that (i) the liquid phase is perfectly mixed; (ii) the vapour phase is alw...

Sugar industry processes release large amounts of wastewater and pollution concentrations. This study focuses on environmental produced by a cane sugar factory (Sampling Assalaya factory) with particular emphasis the chemical properties as an essential feature identifying water in area. The aims to analyze wastewater’s features disparity based Sudanese Standards Metrology Organization (SSMO) st...

barfabad river is one of the most important surface water resources in the west of iran which passes from the south of kerend and through the islamabad city and receives high volume of human and industrial sewage. for assessing the water quality of the river, 8 stations were chosen and 72 samples were taken during 9 months from april 1997 to january 1998 and were analysed according to the stand...

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 ...

The question of whether human behavior could be better explained by assuming that people are capable of extracting from their experience some general principles (rules) or by supposing that they store in memory concrete, individual exemplars (instances) of the situations they deal with was examined in 2 experiments, adopting the Sugar Factory dynamic system control task, that contrasted the pre...

BACKGROUND Tuberculosis is a major public health problem throughout the world. Nearly one third of the world's population is infected with Mycobacterium tuberculosis (MTB) and hence at risk of developing active disease. Tuberculosis is a major cause of morbidity and mortality in Ethiopia, and the country belongs to one of the most affected high burden countries. OBJECTIVE To determine the pre...

Leaded pol analyses are used in sugar factories as an estimation of sucrose for factory control purposes and for cane payment. Health and environmental concerns associated with the use of lead for sample clarification has put pressure on the use of this method. Near infrared (NIR) polarimetry has been investigated as an alternative worldwide and the South African sugar industry has decided to r...
