3. ¿Qué es un abstract?
• Un abstract o resumen del trabajo científico es la parte más importante de tu trabajo de
investigación.
• Se redacta en tercera persona y en pasado haciendo referencia a la investigación realizada.
• Tiene contenido significativo y conclusiones del material de fuente primaria.
• Debe ser inteligible, es decir, esplique el estudio sin necesidad de referirse a la investigación
completa pero no la sustituye.

4. Estructura
Su estructura es organizada:
• Background/ antecedentes
• aim or purpose of research/ objetivo o propósito de la investigación
• method used/ método utilizado
• Findings, results/ hallazgos / resultados
• conclusion/conclusión

5. 1-Background/ antecedentes
The production of cassava starch in Colombia comes mainly
from the northern region of the Cauca Department in small
agricultural industries known as “rallanderías”, in which the
settling of the slurry occurs in channels.

6. 2-aim or purpose of research/ objetivo o propósito de la
investigación
the fact that the settling process determines the capacity of
the starch industry, it is important to evaluate the
sedimentation process performed in rectangular channels (0.3
m high; 0.4 m wide; 165 m long), which are generally used in
the region.

7. 3-method used/ método utilizado
Two main components were evaluated: determination of the
change in the concentration of the slurry entering the settling
zone and determination of the particle size distribution in the
settling zone.

8. 4-Findings, results/ hallazgos / resultados
In relation to the affluent of the channels, it was found that
the concentration of the slurry during strainer operation was
between 0.1 to 6% most of the time; the settling of discrete
particles, for which the Stokes Law may be applied,
predominated. During the settling process, the flow varied
between 0.82 to 1.44 L/s with a predominance of laminar flow
and a hydraulic retention time greater than 150 minutes.

9. 5-conclusion/conclusión
it was concluded that In the first 104m of the channel,
particles greater than 10 μm in size were efficiently retained;
particles between 6,7 to 8,8μm were not retained and were
discharged into local bodies of water, generating
environmental problems.

10. 1-Background/ antecedentes
In Spain young people have their first sexual intercourse at an
earlier age than in other countries; however, little is known
about the relationship between age of sexual debut and
sexual behavior in this population.

11. 2-aim or purpose of research/ objetivo o propósito de la
investigación
was analyzed sexual practices and methods of protection
depending on the age of sexual debut among Spanish
adolescents who are sexually experienced (N = 351).

12. 3-method used/ método utilizado
It was found the mean age was 15.9 years (SD = .75, range:
14-18). Three groups were formed according to the age of
sexual debut reported: early sexual debut (earlier than 15
years), average (15 years) and late (later than 15 years).

13. 4-Findings, results/ hallazgos / resultados
The early sexual debut group reported further mutual
masturbation, vaginal intercourse and oral sex with a higher
number of sexual partners than the rest. Condom use at first
intercourse, percentage of use and consistent condom use
was significantly lower in the early sexual debut group
compared to the others. Sexual debut before 15 years old was
associated with increased risk of sexual infections, deficit in
condom use and increased sexual exposure.

14. 5-conclusion/conclusión
The findings of this study suggest that the age of sexual debut
has implications for the sexual health in young people.
