Ozone is a naturally occurring molecule made up of three oxygen atoms. It has the chemical formula O3.
The word ‘ozone’ is derived from the Greek word óζειν which means “to smell”. Its strong smell allows scientists to detect it in low amounts.
Ozone is found in different levels of the earth’s atmosphere.
About 90% of ozone in the atmosphere is concentrated between 15 and 30 kilometres above the earth's surface (stratospheric ozone).
At this level it provides a protective shield from the sun, we think of this as good ozone.
It is also found at ground level in lower concentrations (tropospheric ozone).
Here ozone is a pollutant that is a key part of smog over cities and we think of it as bad ozone.
Atmospheric data demonstrates that ozone depleting substances are destroying ozone in the stratosphere and thinning the earth’s ozone layer.
Ozone depleting substances are chemicals that include -
chlorofluorocarbons (CFCs); nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine.
halons, group of organohalogen compounds containing bromine and fluorine and one or two carbons.
carbon tetrachloride (CCl4),
methyl chloroform (CH3CCl3),
Hydro-bromo-fluoro-carbons (HBFCs),
Hydro-chloro-fluoro-carbons (HCFCs),
methyl bromide (CH3Br) and
bromochloromethane (CH2BrCl).
They deplete the ozone layer by releasing chlorine and bromine atoms into the stratosphere, which destroy ozone molecules.
These and other ozone depleting substances also contribute, to varying extents, to global warming

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.

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.

2. • It is natural occurring gas found in earth’s
atmosphere.
• It is an allotrope of an oxygen consisting of 3
atoms of oxygen ( O3).
Christian Friedrich Schonbein noticed the
pungent odour and recognized it as the smell
often following a bolt of lightning. In 1839,
he succeeded in isolating the gaseous
chemical and named it "ozone", from the
Greek word ozein meaning "to smell".
3. About 90% of ozone is found in the layer of the
stratosphere located 10 – 50 km above earth
surface.
This is called the OZONE LAYER .
It absorb most of the sun’s UV Radiation.
The ozone layer was discovered in 1913 by the
French physicists Charles Fabry and Henri Buisson
4. Ozone layer depletion,
is simply the wearing
out (reduction) of the
amount of ozone in
the stratosphere.
Ozone depletion
describe a steady
decline of about 4%
per decade in the total
volume of ozone in
earth’s stratosphere
the ozone hole.

6. Catalytic destruction is by atomic halogens. The
main source of these halogen atom is halocarbon,
refrigerants, solvent(chloroform), propellants and
foam blowing agents(HCFCs, halons(firefighting) ,
freon ).
CFC and many other substance are referred as
ozone depleting substance.
Chlorofluorocarbons are used in cosmetic,
pressurised blower , heat detectors.
Carbontetrachloride are used in dry cleaning
sparys,spray adhesive , correction fluid.
7. It was seen in 1970’s by research group from the
British Antarctica Survey(BAS).
The word hole is in context with ozone the ozone hole
is more correctly described as a low concentration of
ozone.
The primary causes of ozone depletion is the presence
of chlorine – containing source gases (CFC’s and
related hydrocarbons).
8. Effect on human life
