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.

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.
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.

5. Renewable Energy – Wind Energy
➢ Wind energy generated by wind turbines is mainly used to generate
electricity. India is world's fifth largest producer of electricity
generation in this area.
Advantages
• Wind turbines (often called windmills) do not release emissions that
pollute the air or water.
Disadvantages
• Installation and maintenance cost is very high.
• Only few places are there in world where wind blow continuously
throughout the year.
6. Renewable Energy – Geo Thermal Energy
➢ Geothermal energy is heat from within the Earth. We can recover this heat as
steam or hot water and use it to heat buildings or generate electricity.
Example
Hot springs , Fumaroles (smoke) , Geysers
Advantages
• Carbon dioxide emission levels are very low. They release less than 1% of the
carbon dioxide.
• .
Disadvantages
Installation cost is very high.
Release various kind of harmful gases.
7. Renewable Energy – Hydro Energy
➢ Hydro energy is generally generated from running water using various
mechanical methods.
Example
Dams
Tidal Barrages
Ocean Thermal Energy Conversion (OTEC) system
Advantages
• Produces very less amount of carbon dioxide.
• It is also being used to control flood and for irrigation purposes.
Disadvantages
• Natural environment is destroyed.
8. Renewable Energy – Biomass Energy
Biomass is organic material made from plants and animals waste.
(microorganisms).
When it is burned, the chemical energy in biomass is released as heat .
Example
Methanol (from animal waste)
Ethanol
Biodiesel(liquid biomass)
Advantages
• Equipment (biogas plant) installation cost is less.
• Helps in garbage reduction.

to electrical energy
Example
DG Sets
Gas Engines
Advantages
• Robust technology
• Supply consistency
Disadvantages
• Unit Generation Cost is Very High
• Lead to Noise & Air Pollution.
• Availability of Petroleum Products
12. Non Renewable Energy – Coal
Coal is a combustible black or brownish-black
sedimentary rock composed mostly of carbon
and hydrocarbons.
For millions of years, a layer of dead plants at the
bottom of the swamps was covered by layers of
water and dirt, trapping the energy of the dead
plants.
The heat and pressure from the top layers helped
the plant remains turn into what we today call
coal .
Disadvantages
• Responsible for 57% of carbon dioxide in the air.
13. Non Renewable Energy – Uranium
➢ Nuclear energy is energy in the nucleus (core) of an uranium-
235 atom. Atoms are tiny particles that make up every object in
the universe.
➢ It can be released from atoms in two ways: nuclear fusion
and nuclear fission.
Advantages
• Even a small amount can release enough energy to light-up
thousand of energy for months. (1 kg uranium-235
corresponds to 2.7 million kg coal equivalent.)
Disadvantages
• After using it in nuclear reactor then also it radioactive
substances is very dangerous for human . Eg : charnobyl
accident and fukushima plant accident.
14. Why we need to Conserve Energy
➢ We have limited fuels available on earth.
➢ Our demand for energy is increasing day-by-day.
➢ It is possible that someday, most of fuels will be exhausted , and we will have to switch to alternate
energy.
➢ -----------------------------------
➢ About 70% of India's energy generation capacity is from fossil fuels, with coal accounting for 40% of
India's total energy
Consumption followed by crude oil and natural gas at 24% and 6% respectively.
➢ By 2030, India's dependence on energy imports is expected to exceed 53% of the country's total
energy consumption. In 2009- 10, the country imported 159.26 million tonnes of crude oil which amount
to 80% of its domestic crude oil consumption .
➢ In India 31% of the country's total imports are oil imports.
15. Energy Conservation
➢ Energy conservation refers to efforts made to reduce
energy consumption.
➢ Energy conservation can be achieved through
increased efficient energy use or reduced
consumption from non- renewable energy
sources.
➢ Energy conservation is often the most economical
solution to energy shortages.
How to Conserve Electricity ?
16. Why we need to Conserve Energy
➢ In India , government has passed “ energy conservation bill, 2001 ” for better utilization of
energy and conservation of the same.
➢ By this act, it is mandatory for energy intensive sectors to get their “energy audit ”
conducted by energy auditor.
➢ Bureau of energy efficiency : this body keeps watch on energy consumption patterns,
develops norm for appliances etc.
➢ Star ratings : BEE has also initiated “star rating system” for electrical appliances e.g. -
CFL’S , geysers, refrigerator, etc.

98% are Induction Motors. Induction Motors consumes 70% of the total Electrical Energy
generated.
Reason for Losses in Induction Motors
Over sized Motors
Rewound Motors
Improper Voltage
Less Efficient Motor – Driven Equipment
Idle Run
21. Energy Saving Ideas – For Induction Motors
Generic Ways to reduce Energy Consumption
Use VFD
Stop Throttling on Pumps
Proper selection of Motors & Pumps
Preventive Maintenance of Motors
Over sized Induction Motor
Sizing of Motors plays a vital Role in Energy Efficiency. It is very difficult to choose a right size of Motor in a single step application.
In any industry while designing the capacity of motor for a particular application involves two/three stages. Over sizing of motor is very common in typical industry
The major reasons for over sizing of motors may be due to :::
Starting torque requirements
Excess cushion & safety factors
Adhoc decisions
Rewound Motors
Rewound Induction Motors are common in Indian Industries. Especially, in Textiles, Paper industries and Un-organised sectors such as small Flour mills, Lathe shop and Agricultural farms. Induction Motors are used even after more than four times rewound.
Presence of carbon: the stator and rotor core is made up of thin stamping (0.28mm to 0.45mm). The stamping are insulated from each other by varnish insulation coating, which consists of hydrocarbon. Therefore while motor coil burns varnish also burns and evaporates. The resulting deposition of some unburned carbon between the stampings deteriorates the magnetic property and hence the magnetic loss increases.
---------
Improper Voltage
The performance of any induction motor will be good, when the voltage/frequency ratio should be maintained constant. If a 380 Volt 50 Hz designed induction motor operated with 415V, 50Hz will lead to excess magnetisation loss. This will be the case in many of the imported motors designed for other frequency and voltage than Indian frequency & voltage.
