"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.

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.
1. Plastics are polymers, chains of molecules produced by smaller molecules called monomers.
Light weight, long durability and comparative low production price have made plastic and
polymer an irreplaceable part of industrial activities. However, they are inert to the microbial
degradation and therefore harmful to the environment in many ways. In the developing
countries like Bangladesh due to low labor cost and less legitimate obstacles plastic recycling
can be a pretty good way to utilize waste non degradable plastics to reduce environment
pollution.
Nowadays demand of plastic and synthetic products in the
commercial and industrial arena is growing quite enormously,
which patronizes technological advancement, but on the other
hand is proving to be a fatal threat to the environment due to
their non-biodegradable nature. In this poster, we are bringing
forth the consequences to which our atmosphere is exposed
and providing a potential solution based on developing
countries like ours, which is plastic recycling.
ABSTRACTINTRODUCTION
Greenhouse
Gases:
Fossil fuels such as
natural gas, oil and
coal are used in
production process
of plastic, emitting
dangerous
greenhouse gases
and toxic chemicals.
As plastic
decomposes gases
are produced,
particularly
methane.
Natural Resources:
Plastics are made
from non-
renewable
resources that,
once depleted,
cannot be replaced.
Landfill Space:
Waste Plastic
occupies large area
in landfill causing
dire problems.
Persistence in the
Environment:
Most plastic is not
biodegradable and
will survive in the
environment for
hundreds of years.
Rather than
biodegrading, plastic
photo-degrades,
breaking down into
smaller and smaller
pieces. Plastic is can
float easily in air and
water, and travel long
distances.
Threat to Marine Life: Every year more than 6 million tons of rubbish
are dumped into the world’s oceans. 80% of this waste is plastic, with
an estimated 46,000 pieces of plastic per square mile of ocean.
Turtles, whales, and sea birds mistake rubbish for food or get
entangled in it causing painful injuries or even death. It is estimated
that marine rubbish, mostly plastic, is killing more than a million
seabirds and 100,000 mammals every year.
Effects on
Environment
Past Plastic Waste Management:
In the past, solid waste management was merely collection
and disposal. In Sanitary landfill method wastes were brought
to disposal site and leveled. Workers sprayed disinfectant
and insecticide which were mixture of Izol, gamaxene and
antimalarialoil or Dipthroxhas. The waste was covered with
one layer of sand.
Overall, plastics in landfills are fairly inert. The majority of
common polymers are not biodegradable. By contrast, the
amount of plastic waste is growing. Polymers have lower
density; consequently plastic waste takes up a larger volume
for relatively little mass as compared to the other household
and industrial wastes.
Solid Waste Management= Collection + Disposal
.Collection:
Plastics can be collected from different agricultural, industrial, municipal
and commercial areas. It can be collected manually as labour cost is
comparatively low in our country.
Cleaning and Sorting:
Once the plastic has been collected, it will have to be cleaned and
sorted using various techniques suitable for respective purpose.
Size Reduction:
Size reduction is done to convert waste into small pieces so that they
can be used properly for further processing. Main steps are:
1. Cutting 2. Shredding 3. Agglomeration
Extrusion and Pelletizing:
Polymer pieces are fed into the extruder, are heated to induce plastic
behavior and then forced through a die to form a plastic spaghetti. The
pelletization process is used to reduce the ‘spaghetti’ to pellets which
can then be used for the manufacture of new products.
Plastic
Recycling Process
It is both tough and unacceptable to collect the used
plastic and re-use them after cleaning or washing only.
Reduce means bio-degradation of plastic wastes which
is also quite troublesome considering most of the
plastics are not bio-degradable or very slowly bio-
degradable.
But, considering the situation in a developing country like
Bangladesh plastic recycling can be very useful for the
following factors:
Low labour and transportation Cost.
Fewer laws to control the standards of the recycled
materials.
Original raw materials are costly
Innovative use of machineries often leads to low entry
costs for manufacture.
Why Recycle Plastic
Not all plastics are recyclable. There are first only 4 of the following 7
types of are commonly recycled:
Contamination of recyclables is a problem because it raises the costs for
collectors, recyclers and the community. Plastic bags, bin liners, and
cling wrap are not recyclable. These plastics can get stuck in the sorting
equipment in recycling facilities causing it to stop or break. Often bottle
tops and lids cannot be recycled with the bottle as they may be made of
a different type of plastic. Polystyrene foam is generally not recyclable.
This includes the spongy black foam trays that meat is often packaged
and takeaway containers and hot drink cups.

The rings from bottlenecks and six-pack holders
need to be cut when you dispose of them to reduce
harm to animals.
The energy saved by recycling one plastic drink
bottle will power a computer for 25 minutes.
4% of oil consumption in Europe is used for the
manufacture of plastic products
Recycling plastic saves twice energy than burning it
in an incinerator.

Facts
CONCLUSION
In summary, recycling is one strategy for end-of-life waste
management of plastic products. It makes increasing sense
economically as well as environmentally and recent trends
demonstrate a substantial increase in the rate of recovery and
recycling of plastic wastes. These trends are likely to continue, but
some significant challenges still exist from both technological
factors and from economic issues relating to the collection of
recyclable wastes, and substitution for virgin material. Recycling of
a wider range of post-consumer plastic packaging will further
enable improvement in recovery rates of plastic waste and
diversion from landfills. Therefore, recycling of waste plastics is an
effective way to improve the environmental performance of the
polymer industry.
