Abstract: According to an example for virtual currency exchange management, a list of virtual currencies that can be exchanged between a first application and a second application is determined, and a virtual currency exchange rate between a first virtual currency in the first application and a second virtual currency in the second application is calculated. The user is authenticated to the first and second application, and in the event that authentication is successful, the first virtual currency associated with the user is decremented based on the exchange rate and the second virtual currency associated with the user is incremented based on the exchange rate. In some examples, a redeemable asset, digital currency, cryptocurrency, or combinations thereof may be exchanged for a virtual currency based on a calculated exchange rate.

Abstract: According to an example for providing dynamic content and pricing, pricing data for at least one item accessible in a software application is loaded, and current profile data for an active user of the software application and historical profile data for a group of users is loaded. A behavior metric is calculated for the active user based on the current profile data of the active user and the historical profile data of the group of users, and a price for the at least one item for the active user is calculated based on the behavior metric. In another example, an item to offer a user is determined based on localization data, and in another example, a combination or sequence of items to offer is determined.

Abstract: The present invention is related with bioplasticizers or primary oleochemical plasticizers and the improved process for obtaining thereof. It refers primarily to epoxydized oleochemical plasticizers produced from vegetable oils, as substitute of traditional petrochemical plasticizers. The process starts with the epoxydized product of natural oils, such as sunflower, linseed, Jatropha curcas, soybean, etc., which are transesterified with an alcohol such as ethylic or methylic, in the presence of a catalyst such as sodium methoxide or sodium hydroxide in order to produce an alkylic esters mixture of the fatty acids that were present in the oil or oil mixture used as raw material in the epoxydized oil production.

Abstract: The present invention is related to an improved process for obtaining oleochemical polyols from oils, principally of a vegetable origin. The polyols obtained consist of a mixture of ethers, esters, primary and secondary alcohols and have the characteristic of being self-compatible with the new blowing agents: hydrochlorofluorocarbons, HCFC's, hydrofluorocarbons, HFC's and hydrocarbons, HC's of a low molecular weight and low boiling point. The process of this invention is characterized because it uses Lewis type acids in such a way that they do not form precipitates and therefore it is not necessary to remove precipitates from the polyol. The process of the present invention makes it possible to obtain polyols with high functionality and controlled reactivity. These characteristics render the product suitable for use as a raw material in the production process of rigid foams, such as polyurethane for spraying, refrigeration and imitation wood, coatings, among others.

Abstract: An acupuncture needle-tank apparatus for mix use comprising a needle of the type used in acupuncture, provided with an internal channel constituting a cannula suitable to let pass a liquid or viscous product therethrough, connected to a tank without piston, containing said product, wherein the cannula has an external diameter under 0.3 mm and the tank being of an external diameter under 15 mm. The tank is further characterized in that it is of a material deformable by simple finger pressure to allow the flow of the product it contains.
