Sustainable Cities

Today, more than half of humanity lives in cities, and this figure is expected to rise to 6 billion by 2050. This requires a rethink of urban planning and management, as rapid urbanization puts unprecedented pressure on the environment and public health. Sustainable cities must be environmentally, economically, socially, and politically healthy, both for the current population and for future generations. These cities are based on four pillars of sustainability:

• Environmental: concerns the ecological footprint, resource consumption, and pollution.
• Economic: concerns job opportunities and attracting investment.
• Social: focuses on quality of life, public health, and social integration.
• Institutional: includes democratic participation

Active Transport

Active transport moves substances across membranes from lower to higher concentration, against the concentration gradient. This process requires cellular energy (ATP) and a carrier protein.

The substance binds to the carrier protein's receptor site on one side of the membrane. ATP changes the protein's shape, releasing the substance on the other side. Active transport occurs only in living, respiring cells.

Factors influencing active transport:

• ATP Production: Increased ATP production increases active transport rate.
• Temperature and Oxygen: These affect respiration and ATP production, thus impacting transport rate.
• Mitochondria: Cells with more mitochondria have higher transport rates due to increased ATP production.
• Poisons: Respiratory

Grasslands

In general terms, a grassland ecosystem is characterized by huge open lands where the vegetation includes different types of grasses with very few trees. There are six main types: tropical grasslands, temperate grasslands, flooded grasslands, tundra grasslands, montane grasslands, and xeric grasslands. Tropical grasslands receive 50-130 cm of rainfall, while temperate grasslands receive 25-75 cm.

Key Characteristics of Grasslands

• Limited annual rainfall
• Dry climate
• Lack of nutrients in the soil
• Frequent droughts and uncertain precipitation
• Frequent forest fires due to semi-arid climate and flash lightning
• Poor vegetation dominated by grasses
• Home to a variety of animal species

Nervous and Endocrine Systems

The nervous system receives external and internal stimuli, interprets them, and decides an appropriate response. The response is executed by the effector organ or tissue. Nervous tissue is made up of cells called neurons.

Stimulus → Nervous System → Effectors → Muscles, Glands

Neuron Structure

• Cell body: The central part of the neuron.
• Dendrites: Extensions of the cell body. They receive the nerve impulse and transmit it to the cell body.
• Axon: A long fiber extending from the cell body. It transmits the nerve impulse to other neurons or effector cells.
• Myelin sheath: This layer protects the axon and increases the speed of the nerve impulse.
• Axon terminals: These are located at the end of the axon. They contain neurotransmitters,

Functions of a Financial Market

• Connecting Buyers and Sellers: Facilitates the meeting of buyers and sellers of financial assets without needing a physical location.
• Issuance and Exchange of Assets: Supports the creation (primary markets) and subsequent trading (secondary markets) of financial assets.
• Price Determination: Establishes the prices of financial assets through various pricing mechanisms, such as supply and demand or predetermined conditions.
• Public Information: Disseminates information about asset prices, trading mechanisms, and pricing systems.
• Providing Liquidity: Ensures that assets can be easily converted into cash without significant loss of value.
• Reducing Transaction Costs: Lowers the costs related to finding counterparts and determining

English Phonetics: A Comprehensive Guide

Vowels

Vowels are defined as speech sounds produced with a relatively open vocal tract, allowing air to flow freely through the mouth. They are characterized by 12 features:

• Direction of the air
• Height of the tongue: high, low, and mid vowels
• Part of the tongue raised: front, central, or back
• Position of the lips: rounded or spread
• Length: short or long

Vowels can be classified as either monophthongs or diphthongs. Monophthongs are single vowel sounds, while diphthongs are combinations of two vowel sounds that glide together.

Consonants

Consonants are defined as speech sounds produced with a constriction or closure in the vocal tract, obstructing the flow of air. They are characterized by 24 features:

• Vocal cords:

Freedom and Human Nature

Humans, though possessing instincts, are not determined by nature. Thanks to our rational capacity, we can choose among a number of possibilities. This capability is known as freedom.

However, certain factors in our behavior do not depend on us. No one chooses their birthplace, gender, or skin color. These are given to us and constitute what Ortega y Gasset called circumstances.

To be free means to be responsible for our actions and accept the consequences of our behavior. Responsibility involves attributing success to our work and accepting failures or errors. If we make a mistake, we must rectify it and accept the punishment.

Moral Norms

A norm is a pattern that governs our behavior, a rule about how we should act. For... Continue reading "Freedom, Responsibility, and Moral Norms: A Philosophical View" »
