How we are polluting environment
• Look at any ecosystem and there could be multiple forms of contamination—
streams full of toxic chemicals from industrial processes, rivers overloaded
with nutrients from farms, trash blowing away from landfills, city skies
covered in smog. Even landscapes that appear pristine can experience the
effects of pollution sources located hundreds or thousands of miles away.
• Pollution may muddy landscapes, poison soils and waterways, or kill plants
and animals. Humans are also regularly harmed by pollution. Long-term
exposure to air pollution, for example, can lead to chronic respiratory disease,
lung cancer and other diseases. Toxic chemicals that accumulate in top
predators can make some species unsafe to eat. More than one billion people
lack access to clean water and 2.4 billion don’t have adequate sanitation,
putting them at risk of contracting deadly diseases.

"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.
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.
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.

resources.
When harmful substances contaminate the
environment, it is called pollution.
Refers to the very bad condition of environment
in terms of quantity and quality.
6. Air Pollution
Any alteration of the physical,
chemical and biological
properties of the atmospheric air.
7. Causes of Air
Pollution Industries.
Automobiles and Domestic fuels.
High Proportion of undesirable gases, such as Sulphur dioxide
and carbon monoxide.
Dust(e.g. cement dust, foundry dust and windblown solid dust)
Mist.
Smoke.
Carbon black.
Aerosols.
8. Effects of Air Pollution
Global warming.
Ozone depletion(Ozone hole).
Acid Rain.
Various respiratory illnesses
10. Water Pollution
Any alteration of the physical, chemical,
biological or radiological properties of a body of
water resulting in the impairment of its purity or
quality
11. Causes of Water Pollution
Sewage and wastewater.
Marine dumping
Industrial waste
Radioactive waste
Oil pollution
Underground storage leakage
Atmospheric deposition
Global warming
Eutrophication
12. Dumping is one of the leading causes of water pollution, and you can
keep freshwater sources from becoming contaminated by refraining from
dumping in them. No matter what you might be dumping, whether it’s
solid or liquid waste or even something you feel might not be all that
harmful, you’ll be introducing a new substance into the water supply.
Do not dump in or around rivers
13. Effects of Water Pollution
Diseases like Cholera.
Malaria.
Typhoid (spread during the rainy season).
Aquatic life gets destroy.
14. How to control water pollution
DO NOT pour fat from cooking or any other type of fat, oil, or grease down
the sink. Keep a “fat jar” under the sink to collect the fat and discard in the
solid waste when full.
DO NOT dispose of household chemicals or cleaning agents down the sink.
Avoid using a garbage disposal. Keep solid wastes solid. Make a compost pile
from vegetable scraps.
Use the minimum amount of detergent and/or bleach when you are washing
clothes or dishes. Use only phosphate free soaps and detergents.
Minimize the use of pesticides, herbicides, fertilizers. DO NOT dispose of
these chemicals, motor oil, or other automotive fluids into the sanitary
sewer or storm sewer systems. Both of them end at the river.
15. Changing Your
Household Habits
Use fewer chemicals to clean your home. It's an easy switch
that makes a big difference. Using toxic chemicals like bleach
