3. • Cassava Production Starch
mainly In The northern Region Of
The Cauca a Colombian
Departament, In Small
Agricultural Industrias Know As
“Rollanderías”.

4. • Evaluate The Sedimentation
Process Performed In
Rectangular Channels (0.3m
High; 0.4m Wide; 165m Long)
Which Are generally Used In The
Region.

5. Two Main Components Were
Evaluated:
• Determination Of The Change In
The Concentration Of The Slurry
Zone, Entering The Settling
Zone.
• Determination Of The Particle
Size Distribution In The Settling
Zone.

6. Slurry Concentration During The
Strainer Operation:
Between 0,1 to 6%.
Settling Process Variation During
The Process:
It Varied Between 0,82 to 1.44
L/S.
With A Predominance Of Laminar
Flow And A Hydraulic Retention
Time Greater Than 150 Mins.

7. • In The First 104m Of The
Channels, Particles Greater Than
10 μm in size were efficiently
retained, particles between 6.7
to 8.8 μm were not retained and
were discharged into local bodies
of water, generating a great
environmental problem.

9. • 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.

10. • Sexual practices and methods of
protection are analyzed
depending on the age of sexual
debut among Spanish
adolescents who are sexually
experienced (N=351). The mean
age was 15.9 years (SD = .75,
range: 14-18).

11. 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).
• The early sexual debut group
reported further mutual
masturbation, vaginal intercourse
and oral sex with a higher number of
rest.

12. 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.

13. • The findings of this study
suggest that the age of
sexual debut has
implications for the sexual
health in young people.
