The studying of how twisted light interacts with chiral matter on the nanoscale is paramount for tackling the challenging task of optomechanical separation of nanoparticle enantiomers, whose solution can revolutionize the entire pharmaceutical industry. Here we calculate optical forces and torques exerted on chiral nanoparticles by Laguerre-Gaussian beams carrying a topological charge. We show ...

Cassava (Manihot esculenta Crantz) plant resists water-deficit stress by shedding leaves leading to adaptive water-deficit condition. Transcriptomic, physiological, cellular, molecular, metabolic, and transgenic methods were used to study the mechanism of cassava abscission zone (AZ) cell separation under water-deficit stress. Microscopic observation indicated that AZ cell separation initiated ...

A large fraction of submicron atmospheric aerosol particles contains both organic material and inorganic salts. As the relative humidity cycles in the atmosphere and the water content of the particles correspondingly changes, these mixed particles can undergo a range of phase transitions, possibly including liquid-liquid phase separation. If liquid-liquid phase separation occurs, the gas-partic...

methods in this study, 150 children diagnosed with liver disease and ascites upon admission to nemazee teaching hospital (shiraz, iran) were examined. patients were divided into spontaneous bacterial peritonitis and sterile ascetic fluid groups according to the pmn count ≥ 250/mm3 in the ascetic fluids. routine laboratory tests were conducted and quantitative c-reactive protein (crp) levels wer...

The mechanisms responsible for mediating the influence of sperm preparation protocols on human sperm function have been investigated. Techniques that involved the separation of motile spermatozoa prior to centrifugation were found to yield sperm suspensions of highest quality. If the spermatozoa were centrifuged prior to isolation of the motile cells, sperm function was impaired. The detrimenta...

Mesothelial lesions pose considerable diagnostic challenges not only because benign tumours, reactive proliferations and malignant mesothelioma can mimic one another, but also because the morphological patterns displayed by malignant mesothelioma can simulate a variety of epithelial and non-epithelial malignancies. Immunohistochemical markers can aid in distinguishing epithelioid malignant meso...

This contribution aims to present a methodology to model and simulate the reactive dividing wall column (RDWC) using commercial software. Feasibility of separation scheme was established with ASPEN DISTILTM. Simulation of flowsheet configuration was performed with ASPEN HYSYSTM, using the two columns model. The reactive zone hosted by the prefractionator was modelled and simulated as backward f...

Some oxidative stress effects, such as lipid peroxidation or the DNA damage, have been extensively assessed and reliable biomarkers have been associated to characterize the degree of the damage, while the attack of reactive oxygen species on proteins and the formation of protein carbonyls were investigated only in the recent years. Taking into account that protein carbonyls may play an importan...

This paper deals with a cellular control architecture and the implementation of reactive algorithms on it. Two examples reveal that, to extend a behaviour-based architecture by equipping it with additional reactive algorithms, the arbitration, otherwise action selection, problem has to be redefined in terms of the interaction laws of the algorithms involved. The principles of modularisation and...
