Have you ever wondered how search works while visiting an e-commerce site, internal website, or searching through other types of online resources? Look no further than this informative session on the ways that taxonomies help end-users navigate the internet! Hear from taxonomists and other information professionals who have first-hand experience creating and working with taxonomies that aid in navigation, search, and discovery across a range of disciplines.
This presentation, created by Syed Faiz ul Hassan, explores the profound influence of media on public perception and behavior. It delves into the evolution of media from oral traditions to modern digital and social media platforms. Key topics include the role of media in information propagation, socialization, crisis awareness, globalization, and education. The presentation also examines media influence through agenda setting, propaganda, and manipulative techniques used by advertisers and marketers. Furthermore, it highlights the impact of surveillance enabled by media technologies on personal behavior and preferences. Through this comprehensive overview, the presentation aims to shed light on how media shapes collective consciousness and public opinion.
0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.

2. Flowering plants
Most flowering plant use
sexual reproduction.
They grow flowers which are
their reproductive organs.
These plants reproduce
through seeds and produce
them in two different ways.
ANGIOSPERMS
AND
GYMNOPERMS
3. Non flowering plants
Non flowering plants do not
produce seeds.
They reproduce asexually using
spores.
There are two groups of non
flowering plants:
FERNS AND MOSSES
4. FLOWERING PLANTS
ANGIOSPERMS
Pollinate flowers to produce
fruits with seeds inside.
Examples: apple tree, cherry
tree… .
GYMNOSPERMS
Have small flowers. They don´t
produce any fruits and their
seeds develop in cones.
Leaves called needles.
Examples: pine tree.
5. NON FLOWERING PLANTS
FERNS
They have roots and strong
stems which grow under the
ground.
They have large leaves called
fronds. They produce spores
inside sori.
MOSSES
They have stem and leaves.
Their roots are called rhizoids.
They produce spores inside
capsule.
6. Parts of the plants
Most plants have three parts: the roots, the stem and the leaves.
ROOTS : the roots hold the plant in the ground. Roots absorb water
and minerals from the ground through the roots hairs.
STEM: the stem hold up the other parts of the plant. It also
transports water and minerals. Water and minerals travel through
the stem to the leaves for photosynthesis.
LEAVES: contain chlorophyll, a green substance which is necessary for
photosynthesis. Leaves have two parts: the petiole and the blade.
Veins carry water and minerals. There are tiny holes called
stomata.

10. Plant nutrition
Plants make their own food through process called photosynthesis.
ROOTS: the roots absorb water and minerals from the soil.
XYLEM CELLS: transport mixture of water and minerals, called
raw sap, through the stem to the leaves.
LEAVES: leaves absorb carbon dioxide(CO2 ) through the stomata.
Cells called chloroplasts, chlorophyll collects solar energy to
transform water, minerals and carbon dioxide into glucose and
oxygen (O2).
PHLOEM CELLS: carry the glucose, the plants food, through the stem
to all the parts of the plant.
12. Respiration
Leaves contain stomata, absorb carbon dioxide and release oxygen.
Plants produce oxygen through the photosynthesis.
At night when photosynthesis stops plants release carbon dioxide.
13. Photosynthesis
Photosynthesis is very important because:
Produce oxygen to
breathe
It consumes carbon
dioxide
It transform water and
minerals into food
