Abstract: Provided is one gene CpRap2 isolated from Carica papaya identified as CpRap2.4b and that includes SEQ. ID NO: 2, as well as the genetic transformation methods for the overexpression of said gene and the obtaining of tolerant non-transgenic plants through grafts. Genetic transformation of plants that overexpress genes CpRap2 and their grafts showed they could survive extreme temperatures up to 12 days for heat and more than 30 days for cold.

Abstract: The present invention relates to an electronic circuit for harvesting energy from ultra-low power sources, said circuit comprising a capacitor module (1), a microcontroller (2), two analog switches (3 and 7), an auxiliary battery module (4), a terminal (5), and an operating mode module (6). The circuit is characterised in that: at least two sources (FE) from a plurality of sources (FE) are connected to the capacitor module (1); and the microcontroller (2) transmits the RC digital signals [1.4] at the capacitor module (1) to the first set of analog switches and changes from an idle state to an active state.

Abstract: A method for obtaining sweet gas, synthetic gas, and sulphur from natural gas. The method includes the steps of removing impurities from the natural gas for obtaining pre-treated natural gas; sweetening the pre-treated natural gas through a separation using a plurality of membranes for obtaining sweet gas and acid gases; ionizing the acid gases to dissociate them into sulphur and synthetic gas with remnants of acid gases; and neutralizing the synthetic gas with remnants of acid gases for generating sweet gas. Likewise, a system is presented on how to implement the method.
