thGAP - BAbyss in Moderno!! Transgenic Human Germline Alternatives ProjectMarc Dusseiller Dusjagr
thGAP - Transgenic Human Germline Alternatives Project, presents an evening of input lectures, discussions and a performative workshop on artistic interventions for future scenarios of human genetic and inheritable modifications.
To begin our lecturers, Marc Dusseiller aka "dusjagr" and Rodrigo Martin Iglesias, will give an overview of their transdisciplinary practices, including the history of hackteria, a global network for sharing knowledge to involve artists in hands-on and Do-It-With-Others (DIWO) working with the lifesciences, and reflections on future scenarios from the 8-bit computer games of the 80ies to current real-world endeavous of genetically modifiying the human species.
We will then follow up with discussions and hands-on experiments on working with embryos, ovums, gametes, genetic materials from code to slime, in a creative and playful workshop setup, where all paticipant can collaborate on artistic interventions into the germline of a post-human future.

Battery - Remove and Install
Removal Procedure
Start By:
a. If equipped, turn the battery disconnect switch to the OFF
position. Refer to Operation and Maintenance Manual,
"Battery Disconnect Switch (if equipped) ".
Batteries give off flammable fumes that can
explode resulting in personal injury.
Prevent sparks near the batteries. They could
cause vapors to explode. Do not allow the jump
start cable ends to contact each other or the
machine.
Do not smoke when checking battery electrolyte
levels.
Electrolyte is an acid and can cause personal
injury if it contacts skin or eyes.
Always wear eye protection when starting a
machine with jump start cables.
Improper jump start procedures can cause an
explosion resulting in personal injury.
Always connect the positive (+) to positive (+) and
the negative (-) to negative (-).
Jump start only with an energy source with the
same voltage as the stalled machine.
Turn off all lights and accessories on the stalled
machine. Otherwise, they will operate when the
energy source is connected.
