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.

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.
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.

with an oil, natural gas or
condensate field that is under
the seabed or to activities
carried out in relation to such
a field.

4. U.S. offshore oil and gas history began in the
late 1880s because of high water at Grand Lake
St. Marys , according to some Mercer County
historians. In California, offshore oil wells were
drilled from piers beginning in 1896 at
Summerland in Santa Barbara County.
In 1938, the first offshore well was constructed
in the Gulf of Mexico. Pure Oil and Superior Oil
Company built a freestanding drilling platform—
a 320-foot by 180-foot freestanding wooden
deck in 14-feet of water about a mile offshore
near Creole, Louisiana Offshore Oil & Gas History - American Oil & Gas Historical Society (aoghs.org)
5. • The largest offshore oil fields in India are
the Mumbai high field. It was formerly
called “the Bombay high field”.
• Bombay offshore field was discovered by a
Russian and Indian oil exploration team
during mapping of the gulf of Khambhat in
1964-67 followed by a detail survey in
1972
• The oil operations are run by india’s oil
and natural gas corporation(ONGC)
• Bombay offshore oilfield 160 km off the
coast of Mumbai , India, in about 75m of
water of the Arabian sea.

7. • The basin is bounded to north and east by
deccan trap out crops of Saurashtra
peninsula and western ghats respectively.
the southern limit is marked by east-west
trending Panjim arch and the western
limit is defined by the shelf edge
basement arch
• Five structural provenance with different
tectonic and stratigraphic events can be
identified with in the basin.

8. • It forms the southward extension of the
Cambey basin and to the west it is
separated from Saurashtra basin by Diu
arch.
• An arm of this depression extends far
south in to Panna-Bassein-Herra block
and further south in to Ratnagiri block.
• The Surat depression has numerous
structural features of different origins like
basement-controlled anticlines,
differential compaction over sand bodies
encompassed by shale, inversion and
growth fault related roll over features
PETROLIUM GEOLOGY OF INDIA PAGE NO-23
9. • This block located east of Mumbai
High/Platform and south of Surat
Depression has three distinct N-S to NW-
SE trending tectonic units which lose their
identity in Miocene.
• The western block is a composite high
block dissected by a number of small
grabens.
10. It is the southward continuation of the
Panna-Bassein-Heera block. This block is
differentiated into four distinct tectonic
units by three sets of NNW-SSE trending
echelon fault systems.
The western block is termed ‘Shrivardhan
Horst’ and to its east is ‘Vijayadurg Graben’
which is also a syn sedimentary sink during
Paleogene and Early Neogene.
