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.

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.

• CONCLUSION
3. INTRODUCTION:
SOLAR IRRADIANCE
(1) Solar energy is referred to as renewable and/or sustainable energy
because it will be available as long as the Sun continues to shine.
(2) Our sun is an excellent source of radiant energy. Solar irradiance is
the power per unit area received from the Sun in the form of
electromagnetic radiation as measured in the wavelength range of the
measuring instrument. Solar irradiance is measured in watts per square
metre (W/m2) in SI units.
(3) Irradiance may be measured in space or at the Earth's surface after
atmospheric absorption and scattering. Irradiance in space is a function
of distance from the Sun, the solar cycle, and cross-cycle changes.
Irradiance on the Earth's surface additionally depends on the tilt of the
measuring surface, the height of the sun above the horizon, and
atmospheric conditions. Solar irradiance affects plant metabolism and
animal behavior.
4. Solar Irraiance
. There are three basic types of solar irradiance:
(i) Direct Normal Irradiance (DNI)
(ii) Diffuse-Scatted
(iii) Reflected short wavelength (solar) radiation
from other surfaces.
5. SOLAR ENERGY COLLECTORS
(1) A solar collector is an object that is used to collect energy from the sun,
which it does by absorbing solar radiation and converting it into heat or
electricity. The material type and coating on a solar collector are used to
maximize solar energy absorption.
(2) Collectors are the starting point for the conversion of sunlight into energy.
They must be designed to efficiently concentrate light while minimizing
fabrication, installation, and operating costs.
(3) A material like aluminum is chosen, as it can absorb heat well.
Solar Collector Efficiency Analysis:
The higher intensity of the irradiance received, then the efficiency of the
collector will also be higher. The slight deviation in the image (for
variations collector covered 100%), which occurred at 9:05 a.m., 11:05
a.m., and 12:05 p.m. is due to the weather factor (cloudy). Overall, the
average efficiency of each of the various openings solar collector that is
open 100% .
6. INSTALLATION EMPACT ON
SOLAR COLLECTOR DUE TO
SOLAR IRRADIANCE:
(1) Let us understand this through a study on the effect of solar collector opening and solar
radiation on thermal efficiency.
(2) During the research, the solar irradiance and temperature of collector are
measured and recorded every five minutes.
(3) Temperature measurement performed on the surface of the absorber
plate, inside of collector, surface cover and the outer side insulator
(plywood). This data is used to calculate the heat loss due to conduction,
convection and radiation on the collector.
(4) The collector thermal efficiency calculated based on the ratio of the
amount of heat received to the solar irradiance absorbed. The results show
that each of openings solar collector has different solar irradiance (because
it was done on a different day) which is in units of W/m2.
(5) These indicate that the efficiency of the collector was influenced by solar
irradiance received by the collector and openings of the collector plate.
7. Conclusion:
S olar power is an immense source of directly useable energy and ultimately
creates other energy resources: biomass, wind, hydropower and wave energy.
M ost of the E arth's surface receives sufficient solar energy to permit low-grade
heating of water and buildings, although there are large variations with latitude
and season. At low latitudes, simple mirror devices can concentrate solar energy
sufficiently for cooking and even for driving steam turbines.
T he energy of light shifts electrons in some semiconducting materials. T his
photovoltaic effect is capable of large-scale electricity generation. H owever, the
present low efficiency of solar P V cells demands very large areas to supply
electricity demands.
D irect use of solar energy is the only renewable means capable of ultimately
supplanting current global energy supply from non-renewable sources, but at the
ex pense of a land area of at least half a million km2 .
S olar irradiance is one of the major factor playing a crucial role in the
installation of solar collector as the absorbpution of the heat by the solar
collector is depending on the solar irradiance as justified earlier.
