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.
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.
"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.
2. TANNERY WASTE
Tanning industry involves conversion of animal skin into an end product useful for
making leather goods such as shoes, bags, purses, belts and clothing.
Tanning of raw skin done either by vegetable tanning process or chrome tanning
process.
The manufacturing process start with the removal of unwanted layers from the
hide, allowing the tanning agent to penetrate the hide and convert it into a pliable
material, which is finished with various colors and surface finishes.
4. SOAKING
Soaking the skin in water to remove the preservative salt and to remove the skin’s stiff
nature.
Soaking may be done for 5-10 days.
It produces a strong but intermittent waste water stream, because the salt water is
discharged occasionally.
This stream contains, in addition to the salt, dirt, dung,
and blood.
It has a dark olive green color.
5. FLESHING
Which removes the fatty tissues from the hides.
This may be done either manually or by mechanical means .
Continuous flow of water is used in this step in order to carry away the fleshing.
The results in generating a continuous stream
of waste water, which is quiet putrescent in
nature.
6. LIMING
In liming, hides are treated with lime and alkaline reducing agent like sodium
sulphide (Na2S).
This chemical helps in the swelling process of the hide.
The hair on the hides or skin are also loosened.
7. UNHAIRING
Loosened hair are removed by mechanical or manual mean.
They are separated from wash water with the help of screens.
Washing of hides also removes excess lime used earlier.
8. BATING
It is done to reduce the pH and It reduces the swelling.
It peptize the fibres and remove the protein-degradation products.
Bating makes the grain silky, slippery, smoother and more porous
and diminishes the wrinkles on the
skin or hide.
9. VEGETABLE TANNING
Vegetable tanning uses tannins , which occur naturally in the bark and leaves
of many plants.
Tannins bind to the collagen proteins in the hide and coat them, causing them
to become less water-soluble and more resistant to bacterial attack.
The process also causes the hide to become more flexible.
Hides are stretched on frames and immersed for several weeks in vats of
increasing concentrations of tannin.
Vegetable-tanned hide is not very flexible and is used for luggage, furniture,
footwear, belts, and other clothing accessories.
10. CHROME TANNING
The process of chrome tanning is of a shorter duration than vegetable tanning and
produces a more resistant leather.
After bating, the hides are subjected to pickling, a process in which sodium
chloride(5%-8% strength) and sulphuric acid (0.75% strength) are used.
The reaction is allowed to continue for 10-16 hours. Tanning is done by charging
the hides in drums containing basic chromium sulphate and sodium chloride.
The latter promotes penetration of the chromium salt into hides.
11. There are few special tanning processes aimed at producing white garments,
lather, etc. in which sheepskin is raw hide.
These skins may be tanned using chrome tanning chemical or alum or even
vegetable tanning agents.
The operations of soaking, fleshing, liming and unhairing are carried out in the
beam house, bating and washing of hides is done in the scrub house. While
tanning, bleaching, fat liquoring and finishing is done in the tan yard.
Washing , liming, bating, tanning, bleaching and dyeing produce strong but
intermittent wastes.
13. This above waste has commercial value, in that the salt can be recovered and
reused.
Hair are used for making plaster binders.
Raw trimmings can be converted into glue and gelatin, or are useful for making
leather board, lime sludge is useful for correcting acidic soils.
Fleshings are used as the poultry feed.
Chrome sludge can be converted into bricks and spent vegetable tan bark is used
as fuel.
14. DISPOSAL OF WASTE WATER
Tannery waste water may be disposed of on land for irrigation or into municipal
sewers or into the sea.
These wastes have very have TDS because of the use of salt as preservatives.
The TDS may be as high as 20,000 mg/L. therefore, the raw hides are dusted
before soaking to remove the dried salt. Further the soaking is done in a series of
tanks and water from the first tank, which has the highest conc. Of salts in it, is
stored in evaporation ponds and the dried salt is disposed of with other
predustings. This step reduces TDS considerably, and now it can be used in
irrigation and cultivation purposes.
