RESUMO
DNA data storage based on synthetic oligonucleotides is a major attraction due to the possibility of storage over long periods. Nowadays, the quantity of data generated has been growing exponentially, and the storage capacity needs to keep pace with the growth caused by new technologies and globalization. Since DNA can hold a large amount of information with a high density and remains stable for hundreds of years, this technology offers a solution for current long-term data centers by reducing energy consumption and physical storage space. Currently, research institutes, technology companies, and universities are making significant efforts to meet the growing need for data storage. DNA data storage is a promising field, especially with the advancement of sequencing techniques and equipment, which now make it possible to read genomes (i.e., to retrieve the information) and process this data easily. To overcome the challenges associated with developing new technologies for DNA data storage, a message encoding and decoding exercise was conducted at a Brazilian research center. The exercise performed consisted of synthesizing oligonucleotides by the phosphoramidite route. An encoded message, using a coding scheme that adheres to DNA sequence constraints, was synthesized. After synthesis, the oligonucleotide was sequenced and decoded, and the information was fully recovered.
RESUMO
Se realizó un estudio descriptivo acerca de las características biopsicosociales de 24 mujeres víctimas de violencia intrafamiliar, que mantuvieron sus acusaciones y decidieron romper el silencio de un universo de 83 que la habían padecido de agosto de 1998 a agosto de 1999. Con el objetivo de conocer características propias de estas y de sus victimarios, se utilizó la entrevista individual, donde se halló que más de la mitad habían retirado sus acusaciones y habían incurrido en una ocasión en el hecho. Las amas de casa de 15 a 24 años fueron las más maltratadas, y las lesiones leves fue el acto violento más reportado. Los victimarios fueron hombres de 25 a 34 años, jefes de núcleo familiar y obreros, con la presencia del alcohol como hábito tóxico común, y este a su vez como la causa condicionante a la violencia
