Natural resources gifted by god -- Edited
Natural resources are the raw materials and sources of energy that we use. Petrol, metals, soil, sand, wind, water, and everything in between are natural resources. Manufactured items such as plastic, sheet metal, fabrics, microchips, electricity and concrete are not natural resources, but are most definitely derived from natural resources.

Petrol, metals, soil, sand, wind, water and everything in between are natural resources. Manufactured items such as plastic, sheet metal, fabrics, microchips, electricity and concrete are not natural resources, but are most definitely derived from natural resources.
Think about the relationship between natural resources and manufactured products. In essence, we call them “natural” resources because they are things human society uses that are created (or were created in the case of fossil fuels) without human intervention.
Perpetually Renewable Resources
Perpetually renewable resources are the easiest resources to understand; these are natural resources that are constantly replenished by the Sun’s and Earth’s natural processes. For example, every day the sun delivers an average of 198 Watts of energy to every square meter (m
) of the Earth’s surface. For comparison a standard incandescent light bulb in a bedside lamp uses 40 Watts, or a 100kg person climbing a step in 2 seconds uses roughly 200 Watts. Every day without fail for the last 5 billion years (plus or minus a few hundred million years) the Sun has delivered this solar energy.
Together with geothermal energy (heat from the Earth’s interior), the Sun’s perpetual energy powers the winds, ocean currents, precipitation and most of the Earth’s plant life. Solar and geothermal natural resources currently energise a significant and growing percentage of many nations’ electrical grids. It is perpetually renewable in the sense that no matter how much we use in terms of human time-scales (e.g decades to millennia), the Sun and the Earth will always make more.
Intermediate Renewable Resources
Intermediate renewable resources are only renewable resources if we don’t use them too quickly. They are resources such as freshwater, soil, crops and trees for timber. If we didn’t use them, they would be perpetually renewable, but because they require time (on human time-scales) to regenerate or grow, we can overuse them until they are no longer available.
Freshwater is a great example of an intermediate renewable resource. Through the water cycle, the sun evaporates water from the surface of saltwater oceans that travels over land and falls back to earth as freshwater rain. This rain fills the lakes, rivers and aquifers we use for agriculture, industry and drinking water. If we use this freshwater at the same rate as the rain recharging it, then we won’t run out. If we use the freshwater faster than it recharges, then we will. Intermediate renewable resources must be carefully managed to ensure they are not depleted.
Non-renewable Resources
The last category of natural resources are the non-renewables. These are resources that will not regenerate on human time-scales. Once they have been depleted they will no longer be available and no more will be made. The most common examples of non-renewable resources are fossil fuels, so-called because most were created by processes that take millions of years. Fossil fuels include crude oil, natural gas, coal and uranium. Other non-renewable resources include metals, lithium and rare-Earth elements (REE’s), but it’s important to remember that while we may eventually run out of mineable metals and REE’s, with careful waste management, these can be recovered through recycling. However, it is not the same for fossil fuels as using them for energy alters their chemistry so they are no longer useful.

By chathu: Fish Farming
Fish farming is an ideal business idea for investors with available land, and it doesn’t always require a large body of water. You can start a fish farm either by creating fish ponds or investing in fish tanks; it’s a highly scalable business idea. Once you have the proper knowledge of fish raising, you will be able to decide the type of fish to raise. According to FinModelsLab, a well-run fish farm can produce a return on investment (ROI) of 15% to 40% annually, with many fish farmers achieving a full return on their investment within three to five years.
Fish such as tilapia, cod, trout, and catfish are popular because they are easy to raise and in high demand. Small-scale farms are the usual suppliers of fish in their local supermarkets and restaurants.
Other popular varieties of commercially-raised fish include:
Yellow Perch
Eel
Grass Carp
Tuna
Salmon
Not all fish are raised for food. Goldfish and koi are popular fish to farm as well. For non-food fish, focus on cultivating premium species that will fetch a higher price when you sell. Whether you are raising fish for food or not, adopting sustainable farming practices will be better for both your business branding and your long-term operational costs.
The decision as to which fish you want to raise will ultimately rely on your skill, financial capacity, market demand, and agro-climatic condition. This refers to the normal soil types, rainfall, temperature, and water availability that affect the type of vegetation in the area.

Types of people who will benefit from the Eisenhower Matrix:
People in leadership positions
Critical thinkers
4. Parkinson’s Law
British historian Cyril Northcote Parkinson became famous for the phrase “work expands so as to fill the time available for its completion.” In other words, the amount of time you give yourself to complete a specific task is the amount of time it will take you to complete that task.
How it works:
This is not a time management technique per se. It’s a law that, when understood, can be applied as one of the most beneficial time management methods out there—but you will have to put in the work. That means working more efficiently in shorter bursts of time. Here are some time management tips:
Try working without a computer charger. This will force you to finish a project before your computer dies.
Get it done early. Instead of finishing an essay by midnight, try to get it done by noon.
Set a deadline. Give yourself a set time to do something—and then cut it in half.
Limit time for tasks. Give yourself only 20 minutes in the morning to answer emails.
Types of people this works for:
Procrastinators
People who work well under pressure
5. Time Blocking Method
Inventor Elon Musk is known for being productive. He manages his time so efficiently that he can work over 80 hours a week and still make time for himself. What’s his secret? Time blocking.

A heart attack occurs when an artery that sends blood and oxygen to the heart is blocked.
Embedded video URL:Normal text:
A heart attack occurs when an artery that sends blood and oxygen to the heart is blocked. Fatty, cholesterol-containing deposits build up over time, forming plaques in the heart's arteries. If a plaque ruptures, a blood clot can form. The clot can block arteries, causing a heart attack. During a heart attack, a lack of blood flow causes the tissue in the heart muscle to die.
A heart attack is also called a myocardial infarction.
Prompt treatment is needed for a heart attack to prevent death. Call 911 or emergency medical help if you think you might be having a heart attack.
Symptoms
Symptoms of a heart attack vary. Some people have mild symptoms. Others have severe symptoms. Some people have no symptoms.
Common heart attack symptoms include:
Chest pain that may feel like pressure, tightness, pain, squeezing or aching
Pain or discomfort that spreads to the shoulder, arm, back, neck, jaw, teeth or sometimes the upper belly
Cold sweat
Fatigue
Heartburn or indigestion
Lightheadedness or sudden dizziness
Nausea
Shortness of breath
Women may have atypical symptoms such as brief or sharp pain felt in the neck, arm or back. Sometimes, the first symptom sign of a heart attack is sudden cardiac arrest.
Some heart attacks strike suddenly. But many people have warning signs and symptoms hours, days or weeks in advance. Chest pain or pressure (angina) that keeps happening and doesn't go away with rest may be an early warning sign. Angina is caused by a temporary decrease in blood flow to the heart.

Natural resources gifted by god --- Edited
Natural resources are the raw materials and sources of energy that we use. Petrol, metals, soil, sand, wind, water, and everything in between are natural resources. Manufactured items such as plastic, sheet metal, fabrics, microchips, electricity and concrete are not natural resources, but are most definitely derived from natural resources.

Petrol, metals, soil, sand, wind, water and everything in between are natural resources. Manufactured items such as plastic, sheet metal, fabrics, microchips, electricity and concrete are not natural resources, but are most definitely derived from natural resources.
Think about the relationship between natural resources and manufactured products. In essence, we call them “natural” resources because they are things human society uses that are created (or were created in the case of fossil fuels) without human intervention.
Perpetually Renewable Resources
Perpetually renewable resources are the easiest resources to understand; these are natural resources that are constantly replenished by the Sun’s and Earth’s natural processes. For example, every day the sun delivers an average of 198 Watts of energy to every square meter (m
) of the Earth’s surface. For comparison a standard incandescent light bulb in a bedside lamp uses 40 Watts, or a 100kg person climbing a step in 2 seconds uses roughly 200 Watts. Every day without fail for the last 5 billion years (plus or minus a few hundred million years) the Sun has delivered this solar energy.
Together with geothermal energy (heat from the Earth’s interior), the Sun’s perpetual energy powers the winds, ocean currents, precipitation and most of the Earth’s plant life. Solar and geothermal natural resources currently energise a significant and growing percentage of many nations’ electrical grids. It is perpetually renewable in the sense that no matter how much we use in terms of human time-scales (e.g decades to millennia), the Sun and the Earth will always make more.
Intermediate Renewable Resources
Intermediate renewable resources are only renewable resources if we don’t use them too quickly. They are resources such as freshwater, soil, crops and trees for timber. If we didn’t use them, they would be perpetually renewable, but because they require time (on human time-scales) to regenerate or grow, we can overuse them until they are no longer available.
Freshwater is a great example of an intermediate renewable resource. Through the water cycle, the sun evaporates water from the surface of saltwater oceans that travels over land and falls back to earth as freshwater rain. This rain fills the lakes, rivers and aquifers we use for agriculture, industry and drinking water. If we use this freshwater at the same rate as the rain recharging it, then we won’t run out. If we use the freshwater faster than it recharges, then we will. Intermediate renewable resources must be carefully managed to ensure they are not depleted.
Non-renewable Resources
The last category of natural resources are the non-renewables. These are resources that will not regenerate on human time-scales. Once they have been depleted they will no longer be available and no more will be made. The most common examples of non-renewable resources are fossil fuels, so-called because most were created by processes that take millions of years. Fossil fuels include crude oil, natural gas, coal and uranium. Other non-renewable resources include metals, lithium and rare-Earth elements (REE’s), but it’s important to remember that while we may eventually run out of mineable metals and REE’s, with careful waste management, these can be recovered through recycling. However, it is not the same for fossil fuels as using them for energy alters their chemistry so they are no longer useful.

Once they have been depleted they will no longer be available and no more will be made. The most common examples of non-renewable resources are fossil fuels, so-called because most were created by processes that take millions of years. Fossil fuels include crude oil, natural gas, coal and uranium. Other non-renewable resources include metals, lithium and rare-Earth elements (REE’s), but it’s important to remember that while we may eventually run out of mineable metals and REE’s, with careful waste management, these can be recovered through recycling. However, it is not the same for fossil fuels as using them for energy alters their chemistry so they are no longer useful.

Symptoms
Symptoms of a heart attack vary. Some people have mild symptoms. Others have severe symptoms. Some people have no symptoms.
Common heart attack symptoms include:
Chest pain that may feel like pressure, tightness, pain, squeezing or aching
Pain or discomfort that spreads to the shoulder, arm, back, neck, jaw, teeth or sometimes the upper belly
Cold sweat
Fatigue
Heartburn or indigestion
Lightheadedness or sudden dizziness
Nausea
Shortness of breath
Women may have atypical symptoms such as brief or sharp pain felt in the neck, arm or back. Sometimes, the first symptom sign of a heart attack is sudden cardiac arrest.
Some heart attacks strike suddenly. But many people have warning signs and symptoms hours, days or weeks in advance. Chest pain or pressure (angina) that keeps happening and doesn't go away with rest may be an early warning sign. Angina is caused by a temporary decrease in blood flow to the heart.

Edited -- gym workout for fat loss and muscle gain
Edited -- To effectively lose fat and gain muscle at the gym, focus on a combination of strength training, cardio, and a balanced diet. Aim for at least two strength training sessions per week, incorporating exercises that work all major muscle groups, and include some cardio to burn calories.
Strength Training:
Full-Body Workouts:
Prioritize compound exercises like squats, deadlifts, lunges, push-ups, and rows, which work multiple muscle groups simultaneously, leading to greater calorie burn and muscle growth.
Squats: Target the lower body and core, building strength and power.
Deadlifts: A powerful exercise for the entire posterior chain, including glutes, hamstrings, and back, boosting strength and metabolism.
Lunges: Engage the legs and glutes, improving balance and stability.
Push-ups: Work the chest, shoulders, and triceps, building upper body strength and endurance.
Rows: Focus on the back and biceps, promoting a balanced physique.
Progressive Overload:
Gradually increase the weight, reps, or sets you lift each week to challenge your muscles and promote growth.
Rest and Recovery:
Allow adequate rest between workouts to allow muscles to repair and rebuild.
Cardiovascular Exercise:
Moderate-Intensity Cardio:
Incorporate activities like brisk walking, jogging, cycling, or swimming for 30-60 minutes most days of the week to burn calories and improve cardiovascular health.
High-Intensity Interval Training (HIIT):
Alternate short bursts of intense exercise with periods of rest or lower-intensity exercise to maximize calorie burn in a shorter time frame.
Examples of HIIT:
Burpees, mountain climbers, and kettlebell swings are great options for HIIT workouts.
Nutrition:
Calorie Deficit: Consume fewer calories than you burn to promote fat loss.
Protein Intake: Ensure adequate protein intake to support muscle growth and repair.
Balanced Diet: Focus on whole, unprocessed foods, including lean protein, complex carbohydrates, and healthy fats.
Hydration: Drink plenty of water throughout the day to support overall health and performance.

Natural resources are the raw materials and sources of energy that we use. Petrol, metals, soil, sand, wind, water, and everything in between are natural resources. Manufactured items such as plastic, sheet metal, fabrics, microchips, electricity and concrete are not natural resources, but are most definitely derived from natural resources.

Petrol, metals, soil, sand, wind, water and everything in between are natural resources. Manufactured items such as plastic, sheet metal, fabrics, microchips, electricity and concrete are not natural resources, but are most definitely derived from natural resources.
Think about the relationship between natural resources and manufactured products. In essence, we call them “natural” resources because they are things human society uses that are created (or were created in the case of fossil fuels) without human intervention.
Perpetually Renewable Resources
Perpetually renewable resources are the easiest resources to understand; these are natural resources that are constantly replenished by the Sun’s and Earth’s natural processes. For example, every day the sun delivers an average of 198 Watts of energy to every square meter (m
) of the Earth’s surface. For comparison a standard incandescent light bulb in a bedside lamp uses 40 Watts, or a 100kg person climbing a step in 2 seconds uses roughly 200 Watts. Every day without fail for the last 5 billion years (plus or minus a few hundred million years) the Sun has delivered this solar energy.
Together with geothermal energy (heat from the Earth’s interior), the Sun’s perpetual energy powers the winds, ocean currents, precipitation and most of the Earth’s plant life. Solar and geothermal natural resources currently energise a significant and growing percentage of many nations’ electrical grids. It is perpetually renewable in the sense that no matter how much we use in terms of human time-scales (e.g decades to millennia), the Sun and the Earth will always make more.
Intermediate Renewable Resources
Intermediate renewable resources are only renewable resources if we don’t use them too quickly. They are resources such as freshwater, soil, crops and trees for timber. If we didn’t use them, they would be perpetually renewable, but because they require time (on human time-scales) to regenerate or grow, we can overuse them until they are no longer available.
Freshwater is a great example of an intermediate renewable resource. Through the water cycle, the sun evaporates water from the surface of saltwater oceans that travels over land and falls back to earth as freshwater rain. This rain fills the lakes, rivers and aquifers we use for agriculture, industry and drinking water. If we use this freshwater at the same rate as the rain recharging it, then we won’t run out. If we use the freshwater faster than it recharges, then we will. Intermediate renewable resources must be carefully managed to ensure they are not depleted.
Non-renewable Resources
The last category of natural resources are the non-renewables. These are resources that will not regenerate on human time-scales. Once they have been depleted they will no longer be available and no more will be made. The most common examples of non-renewable resources are fossil fuels, so-called because most were created by processes that take millions of years. Fossil fuels include crude oil, natural gas, coal and uranium.

Latine Voces Uncensored: Symposium on Latine Narratives
The digital age has brought us virtually (pun, intended) limitless access to information in the digital age. Despite this access, Latine communities continue to confront the challenges of rampant misinformation, censorship and misrepresentation—influencing how Latines are depicted in news coverage to popular culture to domestic and international policies that directly impact (and harm) our communities. Accurate Latine narratives and exposure to our histories are as important as ever. In this timely and important symposium, we address representation and free speech through the lens of Puerto Rican storytelling.
Hosted by Latino Spartans & MSU Chicanx/Latinx Association (ChiLA).
Note: The first half of this event will take place at the Multicultural Center. The Library portion will begin at 1:30 in the Green Room.

Renaissances, Revivals, and Records
Throughout history, humans have been finding ways to revive, rebirth, and reconstruct their favorite artistic practices. Music has been one of the greatest playgrounds for these types of explorations. In acts that both pay homage to the past and push the craft forward, renaissances have revolved around time periods, genres, and even mediums. Join us for an interactive listening party where we take a closer look at some iconic musical revivals, ask how we got here, and wonder where we might go next.
Curated and hosted by: Lilly Korkontzelos, MSU Music Library Student Assistant and master’s student in Music Theory
Location: Music Library (4th Floor West)
