Abstract: Systems and processes for converting light or very light sweet crudes and condensates to chemicals and petrochemicals. The process includes providing a hydrocarbon feedstock comprising a crude oil or condensate having an API gravity of at least 35, a sulfur content of less than 0.2 wt %, and less than 10 wt % of hydrocarbons having a normal boiling point above 575° C. The hydrocarbon feedstock is heated and separated to recover a light fraction, a middle fraction, and optionally a heavy fraction. The light fraction is steam cracked to produce a cracked light fraction and the middle fraction is separately steam cracked to produce a cracked middle fraction. The cracked light fraction and the cracked middle fraction are then separated to recover one or more product fractions including an ethylene fraction and a propylene fraction.

Abstract: A method for stratifying a patient infected with a respiratory disease is disclosed. The method comprises providing (1510) a fluid sample (9) from the patient, producing (1520) a light signal from a laser (1), illuminating (1530) the fluid sample (9) with the light signal through a lens in a sensing probe (8), acquiring (1540) a spectrogram from the fluid sample (9), extracting (1550) a plurality of spectrogram features from the light signal, comparing (1560) the extracted plurality of spectrogram features with a model in a database to determine a degree of severity of the respiratory disease. A result is then output (1570) to indicate the degree of severity of the respiratory disease.

Abstract: A roller-type chain for a bicycle is configured with asymmetrical chain link plates, the chain link plates applicable for use with a chain with reduced chain width as in use on chain drives with a high number of gear ratios. The chain link plates are configured at the inner side of the chain loop for engagement on the teeth of the rear sprocket and of the front chain wheel. The chain link plates are further configured at the outer side of the chain loop for interaction with the chain-guiding roller on the rear gearshift mechanism.

Abstract: Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.

Abstract: The polysaccharide released from the unicellular cyanobacterium Cyanothece sp. CCY 0110 exhibits low cytotoxicity and proves to be suitable for the delivery of macromolecules. The cyanobacterium extracellular polymer disclosed in the present subject-matter, namely a polysaccharide and more in particular an heteropolysaccharide, assembles with proteins into a new phase with gel-like behaviour and the release kinetics can be modulated (i.e., delayed) by adding divalent cations and/or also exhibits physical and chemical properties typical of a bioemulsifier or a bioflocculant.
