Noise Control Stratagies in Reinforced Concrete BuildingsIJRES Journal
This study is aimed at bringing out the salient aspects of building noise control. An analysis has been carried out with respect to the noise transmission as well as the characteristics of noise inside buildings. The key issues on building noise control have been included and discussed. A comprehensive study on building noise and on acoustically divisible spaces has been made. It has been observed that a sound insulation of the order of 30 to 35 dB is possible in a given building. Further, the noise propagation parameters in an exhibition hall have been theoretically estimated. The data so obtained has been compared with actual SPL measurements and recorded. Variations in noise levels observed have been explained. Before the partition is made, the SPL drop is faster inside the building but after the partition the drop falls at the rate of 3dB for doubling the distance. The cost of the acoustically divisible partition wall is found to be very high, but the advantage of this partition seems to be creating acoustically divisible spaces where in one can conduct two programs simultaneously, without any disturbance to each other. Prior to the selection and design of control measures, noise sources must be identified and the noise produced must be carefully evaluated.

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.

"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.

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.

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.

Introduction of Noise Pollution
Sound and Noise
Noise Measurement
Ambient Noise Standard
Sources of Noise Pollution
3. Noise pollution
Noise pollution can be defined as unpleasant and
unwanted sound.
The presence of unwanted and unpleasant sound in the
atmosphere, which may causes discomfort is called
“Noise Pollution”.
Any unwanted, disturbing or harmful sound that impairs
or interferes with hearing, causes stress, hampers
concentration and work efficiency or causes accidents
called “Noise pollution”.
5. Sound and noise
Sound is what we hear.
Sound is a physical phenomenon that stimulates the
sense of hearing, in human beings hearing takes place
whenever vibration of frequencies between about 15 to
20,000 hertz reach the inner ear.
6. Sound and noise
Noise is unpleasant and unwanted sound.
Noise may be defined as any sound that can produce an
undesirable effect to living especially human either
physiologically or may interfere with personal, social or
group activities or work or communication or rest or
recreation or sleep.
Noise is measured by sound level meter.
8. Sound Measurements
Sound pressure:
It is the amount of air pressure fluctuation created by the
source of the sound.
Sound pressure is expressed as Pascal.
A healthy young person can hear sound pressure is low
pressures as low as 0.00002 Pa.
Sound power:
It is the sound energy transferred per second from the
sources (sound) to the air.
Power is expressed in watts (W).
9. Sound Measurements
Sound pressure level (SPL):
Sound pressure converted to the decibel scale is called
sound pressure level.
Decibel (dB) is used in environmental noise pollution as a
measure of sound power level, sound intensity level and
sound pressure level.
It is a ratio expressed on a logarithmic scale. This
logarithmic scale takes care of wide range of sound
power, intensity and pressure.
dB = 10* log (A/A0)
In general, dB of the quantity A, relative to the reference
quantity A0 is defined as above.

4. Other miscellaneous sources
12. Sources of noise pollution
Traffic Sources:
Noise created by various means of transport like trucks,
tractors, buses, trains, aeroplanes, etc. are the traffic
related source of noise pollution.
It may be in the form of:
Horn of vehicles
Raise of accelerator
Vehicle with damaged silencer
Noise produced by a diesel car will be more than that
produced by a petrol car.
A jet aircraft will produce more noise than a propeller type
of aircraft.
