The document discusses advanced nuclear energy technology and its potential to reduce climate mitigation costs. It notes that world energy usage is projected to increase nearly 50% by 2050, led by growth in Asia. This increase combined with rising CO2 emissions from fossil fuel use is exacerbating global warming effects like rising sea levels and temperatures. Nuclear energy produces very low carbon emissions and could help meet rising energy demand while reducing climate impacts compared to fossil fuels. However, advanced technologies are needed to improve nuclear further and reduce its costs to help address climate change at scale.

Water has the chemical formula H2O, making it an inorganic substance. It is the primary chemical component of the Earth's hydrosphere and the fluids of all known living things (in which it serves as a solvent[1]). It is transparent, flavorless, odorless, and almost colorless. In spite of not providing food, energy, or organic micronutrients, it is essential for all known forms of life. Its molecules are made up of two hydrogen atoms joined by covalent bonds and have the chemical formula H2O.
Water contamination occurs when pollutants contaminate water sources and render the water unfit for use in drinking, cooking, cleaning, swimming, and other activities. Chemicals, garbage, bacteria, and parasites are examples of pollutants. Water is eventually contaminated by all types of pollution. Lakes and oceans become contaminated by air pollution. Land contamination may contaminate an underground stream, a river, and ultimately the ocean. As a result, trash thrown on an empty lot can eventually contaminate a water source.
Water is uniquely vulnerable to pollution. Known as a “universal solvent,” water is able to dissolve more substances than any other liquid on earth. It’s the reason we have Kool-Aid and brilliant blue waterfalls. It’s also why water is so easily polluted. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution.
Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.

Diabetes is a rapidly and serious health problem in Pakistan. This chronic condition is associated with serious long-term complications, including higher risk of heart disease and stroke. Aggressive treatment of hypertension and hyperlipideamia can result in a substantial reduction in cardiovascular events in patients with diabetes 1. Consequently pharmacist-led diabetes cardiovascular risk (DCVR) clinics have been established in both primary and secondary care sites in NHS Lothian during the past five years. An audit of the pharmaceutical care delivery at the clinics was conducted in order to evaluate practice and to standardize the pharmacists’ documentation of outcomes. Pharmaceutical care issues (PCI) and patient details were collected both prospectively and retrospectively from three DCVR clinics. The PCI`s were categorized according to a triangularised system consisting of multiple categories. These were ‘checks’, ‘changes’ (‘change in drug therapy process’ and ‘change in drug therapy’), ‘drug therapy problems’ and ‘quality assurance descriptors’ (‘timer perspective’ and ‘degree of change’). A verified medication assessment tool (MAT) for patients with chronic cardiovascular disease was applied to the patients from one of the clinics. The tool was used to quantify PCI`s and pharmacist actions that were centered on implementing or enforcing clinical guideline standards. A database was developed to be used as an assessment tool and to standardize the documentation of achievement of outcomes. Feedback on the audit of the pharmaceutical care delivery and the database was received from the DCVR clinic pharmacist at a focus group meeting.
Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organisms’ complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.
"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.

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 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.

• Primary GHG’s in Earth’s Atmosphere:
• Carbon Dioxide

• Nitrous Oxide (fertilizer/nitrogen)
38. IMPACTS OF GLOBAL WARMING
Potential climate change impacts include:
Agriculture, forestry and fisheries,
Human and animal health
Water resources
Coastal areas
Species and natural areas
39. IMPACTS OF GLOBAL WARMING
• Melting Glaciers: glaciers are large sheets of snow and ice that are found on land all year
long. Warmer temperatures cause glaciers to melt faster than they can accumulate new
snow.
• Over the last 50 years glaciers all over the the world have been melting, and the rate of
melting has been speeding up.
• As glaciers and the giant ice sheets on Greenland and Antarctica melt, they add more
water to the ocean causing sea-level to rise.
41. BY THE END OF THE CENTURY…
• GLOBAL MEAN SURFACE TEMPERATURE COULD
INCREASE BY 1.0 TO 4.5 0 C (BEST ESTIMATES)
• GLOBAL MEAN SEA LEVEL COULD RISE BY 0.18 –
0.59 M
• 11 % OF BANGLADESH'S COASTAL LAND IS
LIKELY GO UNDERWATER, CREATING 7 TO 10
MILLION CLIMATE REFUGEES
42. IMPACTS OF GLOBAL WARMING
• Higher temperatures: GHG’s are trapping more heat in the atmosphere,
which is causing average temperatures to rise all over the world.
• Temperatures have risen over the last 30 years, and 2000-2009 was the
warmest decade ever recorded. As the earth heats up, heat waves are
becoming more common.
• Why does it matter?
• Higher temperatures mean that heat waves are likely to happen more often
and last longer. Warmer temperatures can also lead to a chain reaction of
other changes around the world. Increasing air temperatures also affect the
oceans, weather patterns, snow, ice and plants and animals. The warmer it
gets, the more severe the impacts on people and the environment will be.

gets, the more severe the impacts on people and the environment will be.
44. IMPACTS OF GLOBAL WARMING
• More droughts: A drought is an extended period of dry weather caused by a
lack of rain or snow. As temperatures rise, more moisture evaporates from
land and water, leeaving less water behind.
• Since the 1970s droughts have become longer and more extreme worldwide,
particularly in the tropics and subtropics.
• Droughts are expected to get longer and more severe.
• Why does it matter?
• A drought means there is less water available for drinking, watering crops,
making electricity and hydroelectric dams and other uses.
45. IMPACTS OF GLOBAL WARMING
• Melting Glaciers: glaciers are large sheets of snow and ice that are found on land all year
long. Warmer temperatures cause glaciers to melt faster than they can accumulate new
snow.
• Over the last 50 years glaciers all over the the world have been melting, and the rate of
melting has been speeding up.
• As glaciers and the giant ice sheets on Greenland and Antarctica melt, they add more
water to the ocean causing sea-level to rise.
47. IMPACTS OF GLOBAL WARMING
• Rising sea level: As water gets warmer, it takes up more space. Sea level is
also rising due to melting glaciers and ice sheets.
• Over the past 100 years, the average sea level around the world rose by 7
inches.
• Why does it matter?
• Rising sea level is a threat to people who live near the ocean. Low lying
areas will have more frequent flooding, and very low lying land could be
submerged completely. Rising sea level can also harm important coastal
ecosystems.
48. SO, WHAT CAN WE DO TO SLOW DOWN GLOBAL
WARMING?
• Fuel Efficient Cars (when less gasoline is burned, less carbon dioxide ends
ups in the atmosphere)
• Energy-efficient buildings (Energy Star)
• Nuclear Energy (Splitting uranium atoms apart to make electricity)
• Wind Energy (wind turbines to make electricity)
• Geothermal Energy: Geothermal power plants use heat from deep inside the
Earth to generate steam to make electricity. Geothermal heat pumps tap into
heat close to Earth’s surface to heat water or provide heat for buildings.
• Solar Energy: A photovoltaic cell absorbs light and converts it directly into
electricity.

These changes would result in adverse impacts
on agriculture, water resources, health, forests,
vulnerability to extreme events, and coastal
areas.
Therefore, ACT NOW. Adopt Renewables.
