"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.
WRI’s brand new “Food Service Playbook for Promoting Sustainable Food Choices” gives food service operators the very latest strategies for creating dining environments that empower consumers to choose sustainable, plant-rich dishes.

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.

9. Regulations / Compliance- Part L ‘Criterion 3’
Overheating
− Part L1A of Building Regulations endeavours to address dwelling overheating with
“Criterion 3”
− “The dwelling should have appropriate passive control measures to limit the effect
of heat gains on indoor temperatures in summer”
− This check is often overly simplistic and does not provide an accurate indicator of
overheating risk
− It also does not take account of site constraints, such as acoustics or air quality
− As such, compliance can usually be easily achieved by assuming openable windows
− When windows are simulated closed then compliance can often be achieved with
enhanced mechanical ventilation rates of 2-3 air changes per hour

− Consider thermal mass (albeit generally not helpful in
bedrooms, as it affects night-time temperatures)
Ventilation:
− Practical & effective ventilation opening areas (windows &
doors)
17. Residential Corridors
Overheating
− TM59 stipulates <28oC for under 3% annual hours.
− Utilise lower temperature heating distribution pipework
− Locate risers / utility cupboards so as to minimise horizontal
pipework runs
− Ventilate LTHW risers
− Enhanced insulation to pipework distribution - including bends
and fittings
− Maintain separation of cold water and heating pipework to
avoid temperature pick up
− Utilise smoke ventilation shafts for additional ventilation as a
minimum and consider tempering supply make-up air

23. Ventilation Design Impact
Air Quality
− The importance of improving air quality has been recognised by
the GLA and features in the London Plan.
− A detailed assessment of local sources of air quality would be
undertaken to determine air pollution concentration at the
different façades across the development.
− Air quality mapping can then be completed and risk categories
assigned (similar to Acoustics) to consider whether opening
windows are feasible.
− Typical AQ mitigation measures for apartment ventilation
systems include:
- Inclusion of NOx filtration on the intake air connection of the
MVHR
- Bringing outside air in from roof level via an intake air shaft
25. Regulations / Compliance- Part F
Apartment Ventilation
− Opening windows need to be provided to all habitable rooms for
purge/rapid ventilation.
− Background ventilation to each dwelling to comply with one of
the following systems set out in Part F.
- System 1- Intermittent extract fans and trickle vents
- System 2- Natural passive stack and trickle vents
- System 3- Continuous extract fans and trickle vents
- System 4- Continuous supply and extract system (MVHR)
− Part F minimum mechanical ventilation rates are minimal and
would not meaningfully deal with overheating.
− MVHRs are used in 95% of our residential projects (especially in
London where the heat recovery is needed to meet the GLA
energy targets).
