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

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

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 sexual partners than the 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.
