Then they surveyed high school students across the globe to see if these perceptions hold true world-wide. Afterwards, they present the results and implications of these stereotypes.

Experimental N°1: ESTUDIO DE ACEROS ESTRUCTURALES Y DE CONSTRUCCIÓN SOLDADOS ...Fabian Leandro
1. Introducción
La soldadura de aleaciones ferrosas y su efecto en las transformaciones y cambio de propiedades son temas muy importantes para el ingeniero metalúrgico. En las empresas existe un sin número de aplicaciones donde se fabrica y/o se reparan estructuras. Es de vital importancia tener un conocimiento sobre este proceso y aplicaciones de aceros estructurales y otros.
Adicionalmente existen otros procesos que son necesarios para la fabricación de elementos estructurales soldados. El dimensionamiento de los componentes o kit de fabricación (que luego se arma y posteriormente debe montarse). El corte se realiza con diferentes procesos tales: oxicorte, corte por plasma bajo agua o normal, corte por agua, corte por láser, otros.
El conformado en frío es importante (cilindrado, plegado, estampado, bombeado, otros) para la geometría, dimensiones y tolerancias. Lo anterior tiene
mucha relación con los protocolos (selección de la soldadura, procesos de corte, procesos de soldadura, terminación superficial, la protección de la superficie, dossier de calidad, aporte térmico, precalentamiento previo, carbono equivalente, velocidad de enfriamiento, distensionado térmico o vibraciones o mecánico, otros).
Se aprecia por tanto que el proceso de corte – conformado – soldadura, conlleva a múltiples disciplinas que debe ser cuidadosamente controladas de manera que las modificaciones de la composición química, propiedades mecánicas, microestructura y otras, sean mínimas en reacción con el material original.
2. Objetivos
Visualizar y estudiar experimentalmente los cambios microestructurales y de propiedades en las distintas zonas de la soldadura (zona ZAT, metal base y aporte). Se usaran aceros estructurales del tipo ASTM A 572, HSL (ASTM A 514 Gr B) y SAE 1045.
El Laboratorio se realiza una parte en las dependencias de la Empresa Kupfer Hnos. (Libertad #58, Metro ULA). Aquí se realizará el proceso de soldadura de las muestras. Adicionalmente se visitarán las dependencias de la Empresa, para visualizar los procesos de Oxicorte y Corte con Plasma. Es importante que los estudiantes posean los siguientes elementos de seguridad: zapatos con punta de acero, casco, ropa gruesa (tipo jeans).
Materiales:
Acero HSL ASTMA514/ASTM A 36
Acero ASTM A-572 Acero SAE 1045
3. Experiencia Laboratorio.
A) Soldadura Aceros ASTM A-572; HSL A514; SAE 1045.
B) Ensayos de doblado.
C) Análisis metalográfico, composición y perfil de dureza.
Los ensayos anteriores permiten determinar en forma precisa el comportamiento de los aceros frente a los procesos de corte y soldadura. Es importante asociar la composición química de c/u (carbono equivalente), la microestructura y la dureza.
Los ensayos de dureza y análisis metalográfico pueden realizarse también en las dependencias de Kupfer Hnos.
4. Bibliografía.
1. Metal Handbook Volumen 6 (Pág. 1065-1098).
2. Fichas y normas de los aceros.

A salute to veteransIraq War veteran J.R. Martinez spoke
about overcoming adversity and emerging
stronger as part of Mizzou Veterans Week

J
.R. Martinez was always known as the handsome kid.
Family, friends and even strangers would compli-
ment his suave looks, telling a young Martinez how he
had such a stunning face.
So in 2003, after a roadside bomb in Iraq burnt one-third of
his body, the 19-year-old soldier could only glance in the mir-
ror before despair overwhelmed him.
“I thought ‘I’ll be alive, but I’ll never live,’” Martinez said.
Eleven years later, Martinez has acted on the soap opera
“All My Children,” won the 13th season of “Dancing with the
Stars,” and plays Alfonso Rivera on the show “SAF3.” He also
tours the country as a motivational speaker, and Monday night
he spoke to about 200 people at the Missouri Theatre about
overcoming adversity and emerging stronger. The speech was
part of Mizzou Veterans Week.
Even before the burns, Martinez was no stranger to hard-
ship. His dad left the family when he was 9 months old. His
mother raised him on her own, and she couldn’t afford to send
him to college. He had hoped football would be his ticket to
university — and university would be his ticket to the NFL —
but he didn’t have the grades. So he enlisted in the Army.
It wasn’t the trajectory he had planned, but he immersed
himself in the military — the culture, the camaraderie, the
sense of purpose. “You can’t control what happens, but you
can control your attitude about it,” Martinez said.
That outlook was tested after the blast. He was unable to

news@ColumbiaMissourian.com
In the fourth campus forum for MU’s open
provost position, candidate Garnett Stokes
explained on Monday how she thinks her expe-
riences would contribute to success as provost
at MU.
Stokes is the provost and executive vice presi-
dent for academic affairs at Florida State Uni-
versity. She was interim president of the univer-
sity until midnight Monday. Florida Sen. John
Thrasher was confirmed as
Florida State’s next president
on Nov. 6.
In her forum, Stokes
addressed her experiences
as provost at Florida State,
dean of the Franklin College
of Arts and Sciences at the
University of Georgia and
head of the Department of
Psychology at Georgia.
She said her goals as pro-
vost at Florida State were to improve faculty
morale, raise the university’s research profile,

Student Transportation of America won
the bid to become the transportation pro-
vider for Columbia Public Schools after
the Columbia School Board unanimously
approved the switch at the Monday night
meeting.
School Board members voted for Student
Transportation of America to take over for
the 2015 to 2020 school years, replacing First
Student Inc., which has been the district’s
vendor for the past six years.
The approval is contingent on future con-
tract discussions with Student Transporta-
tion of America, School Board President
Christine King said. The contract will be
brought back to the board in December.
