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.
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.

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.
2. ENVIRONMENTAL CHEMISTRY
Study of the chemical and biochemical
phenomena that occur in the environment.
To study the undesirable changes in our
surroundings that have harmful effects on the
plants, animals and human beings
To study the source, reaction, transport, effects,
and chemical molecule present in the Air, Soil &
water.
3. ENVIRONMENTAL CHEMISTRY
Broad area to study the following:
Contamination of Air, Water & Soil
Environmental Indicators- Pollution parameters
Method of monitoring / testing
Mitigation or Control
Elimination, Recycle , Reduction & Efficient treatment
Green Chemistry- Prevention
4. Why this topic
Earth was formed about 4.5 billion years ago
Life on Earth arose at least 3.5 billion years ago
Human Civilisation started 10000 years before until
environment change s due to nature
Last 200 year environment changes drastically due to human
Environment impact by nature is around 1/3 and 2/3 due to
human
We are responsible for degradation of environment, everyone
contribute directly or indirectly
We should aware the damage we do and how to reduce or
prevent the damage.
It is to be done to the next generation to live as we live and our
ancestors lived.
5. ATMOSPHRIC POLLUTION
Addition of undesirable materials into the atmosphere by natural
phenomena or by human activity.
Air pollution changes the quality of the air and affects flora & fauna.
Air pollutants are Gases and Particulatse
Gasses are oxides of sulphur & nitrogen, hydrocarbons, ozone and
other oxidants etc
Source for Pollution;
Natural (1/3), Vehicles, Domestic, Industries ,
• Volcano, erosion, photo dissociation/ photoionisation
• Burning of fossil fuel, Waste incineration
• Emission from industries, etc
6. Particulate pollutants are dust, mist, fumes, smoke, smog
Minute solid particles or liquid droplets in air.
Sources are from vehicle emissions, smoke particles from
fires, dust particles and ash from industries.
Particles are viable and non-viable
Viable particulates e.g., bacteria, fungi, moulds, algae etc.,
living organisms that are dispersed in the atmosphere which
will cause diseases.
Non-viable particulates: combustion of organic matter
ATMOSPHRIC POLLUTION
7. ATMOSPHRIC POLLUTION
Dust: is fine solid particles produced during crushing,
grinding and attribution of solid materials. Cement and fly ash
from factories etc.
Mists: are produced by particles of spray liquids and by
condensation of vapours in air.
Fumes/ vapours: are generated by various operation like
chemical reactions, condensation, sublimation, distillation,
boiling etc...
Air borne particles are dangerous for human health
8. ATMOSPHRIC POLLUTION
SMOG (smoke and fog): common air pollution from major cities
Classical smog or reducing smog: it occurs in cool humid
climate. It is the mixture of smoke, fog and sulphur dioxide.
Photochemical smog: occurs in warm, dry and sunny climate.
Reaction components due chain reaction by sunlight on
unsaturated hydrocarbons and nitrogen oxides and free oxygen
atom
It has high concentration of oxidizing agents and is, therefore,
called as oxidizing smog.
• NO2+ O2 + hν → NO + O3
• O3 + hν → O + O2
• O + H2O → 2 OH [OH] ~ 106
molecules/cc
• OH radical is dominant oxidizer in troposphere!
9. Water Pollution
Pollution of water is due to human activities.
Major contamination is from domestic (municipal) discharged
water and industries.
Organic matter such as leaves, grass, trash etc. Excessive
phytoplankton's growth within water.
Bacteria decomposes the above organic matter and consume
oxygen dissolved in water.
Pathogens: Disease causing microorganisms called pathogens
and harmful bacteria
Micro organism enter water from domestic sewage and animal
excreta.
10. Water Pollution
Domestic waste: soaps, detergent, refectories etc
Industries are major source for water pollution,
Hazardous, toxic organic chemicals
Heavy metals such as cadmium, mercury, nickel etc. All these
metals are dangerous to human body.
Pathogens: Disease causing microorganisms called pathogens
and harmful bacteria
Micro organism enter water from domestic sewage and animal
excreta.
11. Soil pollution
Soil pollution/contamination is caused by chemicals from Waste
dumping, Pesticides and Insecticides, Urbanization & Mining
etc.
Waste dumping :
Industrial solid wastes and sludge
Industrial emissions such as fly ash from thermal power plants
Radioactive materials affects the soil for long periods of time,
Mining :
Mining also affects ground and surface waters, the aquatic life,
vegetation, soils, animals, and the human health.
Acid mine drainage can kill aquatic life.
Toxic metals and chemicals released by mine
12. Soil pollution
Pesticides :
Many of the chemicals used in pesticides are persistent soil
contaminants, which adversely affect soil conservation.
The use of pesticides decreases the biodiversity in the soil. reduced
nitrogen fixation
Animals may be poisoned by pesticide residues that remain on food
after spraying
Poisoning from pesticides can affects the food chain and bio-
acculmulates
13. Waste Management
Waste management is the collection, transport, processing or
disposal, managing and monitoring of waste materials.
It is to reduce their effect on health, the environment or
aesthetics.
All waste materials like solid, liquid, gaseous or radioactive
substances, and tried to reduce the harmful environmental
impacts of each through different methods.
Control of population growth.
Reduce burning of fossil fuels & forests.!
It is by Avoidance & Reduction methods
14. AVOIDANCE & REDUCTION METHODS:
3Rs: Removal, Reduction & Reuse/Recycle:
An important method of waste management is the prevention of
waste material being created.
Efficient method to reduce the waste.
Reuse or Recycle:
Repairing broken items instead of buying new –
Designing products to be refillable or reusable
Avoid using disposable products
Bio-decomposable eg Jute or cotton bags
Removing any food/liquid remains from cans
15. Green chemistry
1. Rather than worry about waste disposal, it is better to avoid
creating waste.
2. Try to generate as little waste as possible, and try to make
waste that is nontoxic (convert toxic into non-toxic).
3. Be energy conscious in designing syntheses
4. Catalysts that allow the use of safe chemicals should be
employed when possible.
5. Try to use renewable feed stocks as raw materials.
6. Try to reduce the amount of solvent used, and try to use
environmentally friendly solvents.
16. Green chemistry
Green chemistry also called sustainable chemistry:
Design or develop the products and processes that minimize
the use and generation of hazardous substances.
While environmental chemistry Green chemistry is the
chemistry of the natural environment, and of pollutant chemicals
in nature, green chemistry seeks to reduce and prevent
pollution at its source.
The focus is on minimizing the hazard and maximizing the
efficiency of any chemical choice.
Use of supercritical carbon dioxide as green solvent
Aqueous hydrogen peroxide for clean oxidations –
Use of hydrogen in asymmetric synthesis
18. Environmental Awareness
As scientists, we are morally obliged to consider the
consequences of our acts.
We create a molecule for profit but must consider its
harm when discarded.
plastic bottles now biodegrade and are no longer immortal.
non-chlorinated refrigerants now cool beer without
sacrificing the Ozone Layer.
Engine exhaust components
Rich mix minimizes NO, maximizes CO, hc
• Run a little rich and catalytically kill CO to CO2
