RAMAN SPECTROSCOPY METHOD AND SYSTEM FOR MONITORING INVASIVE SPECIES IN ALGAL BIOREACTORS

NºPublicación: WO2022269464A1 29/12/2022

Solicitante:

THE STATE OF ISRAEL MINISTRY OF AGRICULTURE & RURAL DEVELOPMENT AGRICULTURAL RES ORGANIZATION ARO [IL]

Resumen de: WO2022269464A1

A method and system for monitoring invasive species in an algal bioreactor utilizes a low resolution Raman spectrometer (LRRS) system and signal processing methods based upon Support Vector Machine (SVM) models. A spectrum preprocessing algorithm transforms LRRS spectra into normalized spectral data vectors. An ex-situ method is used to analyze a calibration set of known samples of a suspension containing a desired biomass, such as spirolina, together with various concentrations of invasive algal or cyanobacterial species. The ex-situ method generates SVM models and their associated SVM support vectors for classification modeling. An in-situ method uses the SVM models to provide an output vector of probability values corresponding to the presence of invasive species in an unknown sample, and optionally to provide an additional output vector of probability values corresponding to concentrations of the invasive species in the unknown sample.

Composition, methods and rationale for the formula of a pre- probiotic dietary supplement aimed at protecting the human body from the harmful effects of electromagnetic radiations through quantum entanglement of DNA repair genes elicited by natural superluminal particles inducing photosynthesis via Cherenkov effect

NºPublicación: US2022401502A1 22/12/2022

Solicitante:

RUGGIERO MARCO [US]

Resumen de: US2022401502A1

This invention relates to a product that is formulated with the goal of protecting the human body from the harmful effects of ionizing and non-ionizing electromagnetic radiations. Examples of ionizing radiations addressed by this invention include, but are not limited to, gamma- and X-rays. Non-ionizing electromagnetic radiations include, but are not limited to, radio waves such as those used for mobile telecommunication comprising the fifth generation technology standard for cellular networks, also known as 5G.This invention is based on biological quantum entanglement occurring at the level of DNA repair genes of commensal microorganisms (cyanobacteria) that are extremely resistant to the killing effects of electromagnetic radiations. The DNA repair genes that are described in this invention are those involved with the repair of DNA lesions observed as consequence of exposure to ionizing and non-ionizing radiations. Expression of these genes in cyanobacteria is induced by their culture in a medium of carbonated mineral water naturally containing the radioactive isotopes 228U and its product of decay, 226Ra. Superluminal particles emitted by these isotopes are the source of Cherenkov radiation that, in turn, stimulates photosynthesis in the cyanobacteria. Photosynthesis is a phenomenon based on quantum entanglement; simultaneous induction of DNA repair genes and photosynthesis, enables entanglement between the DNA repair genes of cyanobacteria and those of commensal microorga
