Sunlight heats the greenhouse air temperature and tomato cracking decreases marketable product up to 90%. A shade screen reduced incoming radiation during warm and sunny conditions to reduce tomato cracking. A fuzzy controller managed greenhouse irrigation to reduce tomato cracking using as variables solar radiation and substrate temperature. The embedded controller presented 9 rules and three ...

Abstract Simulation of heavy oil thermal cracking process is very important but few researches have been published now. In this paper, a simulation framework based on the carbon number-based approach(CNCA) has been established. A systematic division rule is put forward for dividing cracked products into 59 carbon number components. Then the cracking reaction network has been structured and the ...

analytical detection of cracking in connections of steel moment resisting frames using simple damage indices is important since these cracks are not visible unless the connections are uncovered. in this paper, applicability of three cumulative damage indices for detection of cracking in a cover plate welded moment connection is investigated. the damage indices considered in this study are based...

Given that concrete masonry walls are expected to experience shrinkage combined with thermal expansion and contraction, and in some cases even carbonation, throughout their service life, cracking is to be expected. However, after concrete masonry walls have been placed into service, originally anticipated and accounted for cracking is often misdiagnosed as a structural defect. Such misdiagnoses...

Though many diagnostic PCR methods have been described, few techniques have been developed to rapidly and efficiently screen transformed bacterial colonies for plasmid presence (1). Unfortunately, PCR screening of a large number of colonies is time consuming and requires substantial amounts of polymerase and primers. In this report, we describe a two-step large-scale bacterial colony screening ...
