Abstract: The present invention is related to a security label with tampering traces that contains variable, random and unrepeatable information, generated by an algorithm that encrypts it, with a top layer visual cover. The present invention corresponds to a product and method, where said label is associated with an App software (from Smartphones or other mobile devices) for reading the variable information from the label of the bottom layer once the top layer is removed and exposes the information to be read in order to determine the origin or legality of the product. Likewise, the label of the present invention allows to make the traceability of the product and allows to determine if the same one has been adulterated, falsified, being robed, or if on the contrary, it is legal and original and can be suitable for its use, consumption and others.

Abstract: Provided herein are improved methods for the synthesis of reactive conjugate clusters and intermediates used in such methods. In particular, improvements are provided that enhance the synthesis of reactive conjugate clusters by reducing the number of synthetic steps required. The reactive conjugate clusters prepared using the improved methods don't include any transacylation impurities that are formed using existing methods. The improved methods also provide an increase in overall yield and a cost benefit over existing methods.

Abstract: The present invention provides compounds and methods of using them for preparing bicyclic nucleosides. The bicyclic nucleosides are useful for preparing chemically modified oligomeric compounds. Oligomeric compounds comprising these bicyclic nucleosides have enhanced properties such as increased nuclease resistance.

Abstract: Particular combinations of two or more C.sub.12 -C.sub.22 fatty acid esters of C.sub.2 -C.sub.12 polyhydroxy compounds with C.sub.2 -C.sub.12 alcohol and a masking agent provide lubricants for aqueous well fluids having synergistic lubricity and cake conditioning properties in reducing torque and sticking in wells for natural resource fuel and/or mineral materials.
