Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

Sources of Outdoor Air Pollutants
Urban Air Pollution
Effects of Air Pollution
Controlling Air Pollution
4. ATMOSPHERE AS A RESOURCE
Atmospheric Composition
Nitrogen 78.08%
Oxygen 20.95%
Argon 0.93%
Carbon dioxide 0.04%
Ecosystem services
Blocks UV radiation
Moderates the climate
Redistributes water in the hydrological
cycle
5. TYPES AND SOURCES OF AIR POLLUTION
Air Pollution
Chemicals added to the atmosphere by natural events or human
activities in high enough concentrations.
Two categories
Primary Air Pollutant
Harmful substance that is emitted directly into the atmosphere.
Secondary Air Pollutant
Harmful substance formed in the atmosphere when a primary air
pollutant reacts with substances normally found in the atmosphere or
with other air pollutants.
8. MAJOR CLASSES OF AIR POLLUTANTS
Particulate Material
Nitrogen Oxides
Sulfur Oxides
Carbon Oxides
Hydrocarbons
Ozone
9. PARTICULATE MATERIAL
Thousands of different solid or liquid particles
suspended in air.
Includes: soil particles, soot, lead, asbestos, sea salt, and
sulfuric acid droplets.
Dangerous for 2 reasons -
May contain materials with toxic or carcinogenic effects.
Extremely small particles can become lodged in lungs.
10. NITROGEN AND SULFUR OXIDES
Nitrogen Oxides
Gases produced by the chemical interactions between atmospheric
nitrogen and oxygen at high temperature.
Problems
Greenhouse gases
Cause difficulty breathing
Sulfur Oxides
Gases produced by the chemical interactions between sulfur and oxygen
Causes acid precipitation.
11. CARBON OXIDES AND HYDROCARBONS
Carbon Oxides
Gases carbon monoxide (CO) and carbon dioxide (CO2)
Greenhouse gases
Hydrocarbons
Diverse group of organic compounds that contain only hydrogen and
carbon (ex: CH4- methane)
Some are related to photochemical smog and greenhouse gases
12. OZONE
Tropospheric Ozone
Man- made pollutant in the lower atmosphere
Secondary air pollutant
Component of photochemical smog
Stratospheric Ozone
Essential component that screens out UV radiation in the upper atmosphere
Man- made pollutants (ex: CFCs) can destroy it
13. SOURCES OF OUTDOOR AIR POLLUTION
Two main sources
Transportation
Industry
Intentional forest fires is
also high
14. URBAN AIR POLLUTION
Photochemical Smog (ex: New Delhi below)
Brownish-orange haze formed by chemical reactions involving
sunlight, nitrogen oxide, and hydrocarbons.
16. EFFECTS OF AIR POLLUTION
Low level exposure
Irritates eyes
Causes inflammation of respiratory tract
Can develop into chronic respiratory diseases
17. HEALTH EFFECTS OF AIR POLLUTION
Sulfur Dioxide and Particulate material
Irritate respiratory tract and impair ability of lungs to exchange gases
Nitrogen Dioxides
Causes airway restriction
Carbon monoxide
Binds with iron in blood hemoglobin
Causes headache, fatigue, drowsiness, death
Ozone
Causes burning eyes, coughing, and chest discomfort
18. CHILDREN AND AIR POLLUTION
Greater health threat to children than adults
Air pollution can restrict lung development
Children breath more often than adults
Children who live in high ozone areas are more likely to
develop asthma.

20. OTHER WAYS TO IMPROVE AIR QUALITY
Reduce sulfur content in gasoline from its current average of 330 ppm
30ppm
Sulfur clogs catalytic converters
Require federal emission standards for all passenger vehicles
Including SUVs, trucks and mini vans
Require emission testing for all vehicles
Including diesel
21. OZONE DEPLETION IN STRATOSPHERE
Ozone Protects earth from UV radiation
Part of the electromagnetic spectrum with wavelengths just shorter than
visible light
22. OZONE DEPLETION IN STRATOSPHERE
Ozone thinning/hole
First identified in 1985 over Antarctica
Caused by
human-produced bromine and chlorine
containing chemicals
Ex: CFCs
23. OZONE DEPLETION IN STRATOSPHERE
Hole over Antarctica requires two conditions:
Sunlight just returning to polar region
Circumpolar vortex- a mass of cold air that circulates around the
southern polar region
Isolates it from the warmer air in the rest of the planet
Polar stratospheric clouds form
Enables Cl and Br to destroy ozone
24. EFFECTS OF OZONE DEPLETION
Higher levels of UV-radiation
hitting the earth
Eye cataracts
Skin cancer (right)
Weakened immunity
May disrupt ecosystems
May damage crops and forests
25. RECOVERY OF OZONE LAYER
Montreal Protocol (1987)
Reduction of CFCs
Started using HCFCs (greenhouse gas)
Phase out of all ozone destroying chemicals is underway
globally
Satellite pictures in 2000 indicated that ozone layer was
recovering
Full recovery will not occur until 2050
26. ACID DEPOSITION
Sulfur dioxide and nitrogen dioxide emissions react with water vapor in the
atmosphere and form acids that return to the surface as either dry or wet
deposition.
pH scale:-
28. EFFECTS OF ACID DEPOSITION
Declining Aquatic Animal Populations
Thin-shelled eggs prevent bird
reproduction
Because calcium is unavailable in acidic soil
Forest decline
Ex: Black forest in Germany (50% is
destroyed)
30. AIR POLLUTION AROUND THE WORLD
Air quality is deteriorating
rapidly in developing
countries
Shenyang, China
Residents only see sunlight a few weeks
each year
Developing countries have older
cars
Still use leaded gasoline
5 worst cities in world
Beijing, China; Mexico City, Mexico;
Shanghai, China; Tehran, Iran; and Calcutta,
India
31. INDOOR AIR
POLLUTION
Pollutants can be
5-100X greater
than outdoors
Most common:-
Radon, cigarette smoke,
carbon monoxide,
nitrogen dioxide,
formaldehyde pesticides,
lead, cleaning solvents,
ozone, and asbestos
