- Lapse rate is the decrease of air temperature with increasing elevation in the troposphere. It is influenced by factors like dry adiabatic lapse rate (DALR), wet adiabatic lapse rate (WALR), and environmental lapse rate (ELR).
- The stability of the atmosphere depends on the relationship between the ELR and the DALR/WALR. If ELR > DALR, the atmosphere is unstable. If ELR < DALR, the atmosphere is stable. If ELR = DALR, the atmosphere is neutral.
- Radiosondes are instruments used to measure atmospheric variables like temperature, pressure, humidity at different

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 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.
Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
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.

Lapse rate and stability conditions
1. Lapse rate and Stability

2. Lapse rate
• Lapse rate is rate of change in temperature
observed while moving upward through the
Earth’s atmosphere (troposphere to be specific).
• Lapse rate is also defined as negative of
temperature gradient (dT/dZ) in the atmosphere.
The lapse rate is considered positive when the
temperature decreases with elevation, zero when
the temperature is constant with elevation,
and negative when the temperature increases
with elevation.

levels

4. What is air parcel?
• An air parcel refers to a volume of air, large
enough to contain a great number of molecules,
but small enough so that energy (heat) and mass
(air molecules) are nearly constant within its
boundaries.
• An air parcel is commonly portrayed as a three
dimensional cube or sphere. Air parcels can be
expanded and compressed, but the outside air is
assumed not to be able to mix with air inside;
essentially making an air parcel a sealed
container.
5. Adiabatic process
• In thermodynamics, an adiabatic process is
one that occurs without transfer
of heat between a thermodynamic system and
its surroundings.( dq=0 )
6. Adiabatic lapse rate
• Adiabatic Lapse Rate is the rate of fall in
temperature of a rising or a falling air parcel
adiabatically.
• Adiabatic or adiabatically: Heat doesn’t enter
or leave the system. All temperature changes
are internal.
• Adiabatic lapse rates are usually differentiated
as dry or wet (moist).
7. Dry Adiabatic Lapse Rate (DALR)
• Assume the atmosphere to be a stationary
column of air in gravitational field, and the air
is approximated as a dry ideal gas.
• The expansion is rapid enough that we
assume that no heat transfer takes place.
• The change in temperature with elevation is
due to adiabatic expansion is determined in
the following manner.
8. Wet adiabatic lapse rate (WALR)
• When an air parcel that is saturated with water
vapour rises, some of the vapour will condense
and release latent heat [Additional Heat from
inside]. This process causes the parcel to cool
more slowly than it would if it were not
saturated.
• The moist adiabatic lapse rate varies considerably
because the amount of water vapour in the air is
highly variable. The greater the amount of
vapour, the smaller the adiabatic lapse rate.
9. • Approximately, the saturated lapse rate or
WALR is roughly 3.4° F/1000ft or 6 °C/1000m.
10. Significance in meteorology
• The difference between the normal lapse rate
in the atmosphere (environmental lapse rate)
and the dry and moist adiabatic lapse rates
determines the vertical stability of the
atmosphere.
11. Environmental lapse rate
• The environmental lapse rate (ELR), is the rate
of decrease of temperature with altitude in
the atmosphere at a given time and location.
• Temperature at various elevation can be
measured using radiosonde.
• The normal or standard lapse rate based on
international convention is 0.66°C/100 m or
3.6° F/1000ft.
12. Radiosonde
• A radiosonde is a battery-
powered instrument package
carried into the atmosphere
usually by a weather balloon that
measures various atmospheric
parameters and transmits them
by radio to a ground receiver.
Modern radiosondes measure or
calculate the following
variables: altitude, pressure, tem
perature, relative humidity, wind
speed and wind direction, cosmic
ray readings at high altitude
and geographical position
(latitude / longitude). Source: http://radioclubtigullio.weebly.com/radio-sonde.html
13. Stability conditions
• The degree of stability of the atmosphere
must be known if we wish to estimate the
ability of atmosphere to disperse pollutants it
receives from man made sources.
• Mixing in atmosphere depends upon
1. The temperature gradient
2. Mechanical turbulence
15. If the ELR > DALR , then the atmosphere is said
to be superadiabatic.
Source: http://mytutorial.srtcube.com/air-pollution-dispersion/environment-science/693-446#7393
17. If the ELR < DALR , then the atmosphere
is said to be subadiabatic.
Source: http://mytutorial.srtcube.com/air-pollution-dispersion/environment-science/693-446#7393
18. Neutral atmosphere
• When the ELR=DALR , the stability of
atmosphere is said to be neutral.
• Any parcel of air is carried rapidly downwards
or upwards will have the same temperature at
the new height. Hence there is no tendency
for any further vertical movement and the
displaced particle remains in displaced
motion.
19. Potential temperature Gradient
• The stability of atmosphere is also frequently
characterised by the potential temperature
gradient.
• The gradient of environmental temperature
may be expressed in terms of gradient of ELR
and DALR.
20. When the value for the above equation is
1. Negative: unstable atmosphere
2. Positive: stable atmosphere
3. Zero: neutral atmosphere
