Subject: A study on analytical techniques and statistical design for tertiary treatment of secondary wastewater using Zetag-4120 coagulant
Keywords: Polyelectrolytes, regression prediction model, response surface methodology, tertiary wastewater treatment, Zetag-4120.
Abstract: The primary and secondary wastewater treatments from
different sewage treatment plants are of great importance not only for removing pollutants but also for
using treated water for different purposes. The latter
involves using suitable coagulants and their optimal
dosages for the treatment. Given this, the present study
identified the most suitable coagulant for tertiary
treatment and its optimal dosage to achieve the maximum total suspended solids (TSS) and biological oxygen
demand (BOD) removal. We used six coagulants (alum,
ferric chloride, polyaluminium chloride (PAC), Zetag4120, Mecafloc-25 and Rothfloc-27) and found that
Zetag-4120 is the cost-efficient coagulant at varying
coagulant dosage. We arrived at this conclusion based
on several experiments using varying coagulant dosages.
Furthermore, the regression prediction models for BOD
and TSS removal for coagulant Zetag-4120 have been
generated using statistical models and validated by
calculating R2 value, F-test and Lack-of-fit test using
ANOVA. Optimization analysis suggests the optimal
dosage, initial wastewater pH and settling time to be
1.86 mg/l, 6.73 and 89.12 min respectively. Furthermore,
BOD and TSS removal efficiency values are 50.0% and
92.4% respectively. The treated wastewater has BOD
and TSS equal to 12.27 and 5.66 mg/l respectively, conforming to the standard for re-usability of treated water
for unrestricted irrigation.

Keywords: Betweenness centrality, cancer gene identification, degree centrality, eigenvector centrality, protein interaction network
Abstract: Early cancer diagnosis is critical as it can help avoid
the risks associated with long-term treatments and
even prevent death. Identifying a defining trait of a
cancer protein within its protein–protein interaction
(PPI) network could lead to a significant breakthrough
in accelerating early cancer detection. A systematic
analysis of various topological properties of cancer
proteins in the PPI network, focused on their fractal
dimension, was conducted. It was observed that cancer
proteins exhibit a high fractal dimension (with an average of 1.21). Those with the highest fractal dimension
play a significant role in multiple mutation pathways.
The observation that TP53 protein occupying high
fractal dimension of 1.68, connected with 48 communities reaffirm the correctness of the approach. Further
research in this area will provide valuable insights into
the structural and functional complexity of cellular
processes regulated by proteins, leading to the development of robust therapeutic approaches and enhancing our understanding of cancer biology.

Subject: Market competition for imported agricultural raw materials in the Indian animal feed industry
Keywords: Agricultural feed ingredients, feed industry, import competition
Abstract: The Indian animal feed industry, crucial for sustaining
the country’s livestock and poultry sector, heavily relies
on a diverse range of feed ingredients such as soybean
meal, corn, wheat, broken rice, and various energy and
protein sources. Several of these commodities are in
short supply for various reasons, including but not limited to stagnant productivity. Most of these commodities
are imported from the world market to meet the supply
shortage. The present study investigates the market
competition among the exporting countries from which
India imports 13 specific agricultural raw materials
for feed ingredients over the decennial years of 2000,
2010 and 2020. We utilize data from the United Nations
Comtrade database.
Our analysis reveals India’s significant dependency
on specific Asian nations, notably China, as a key source
of these agricultural raw material imports. Import
costs vary, prompting India to diversify its sources of
imports of these agricultural commodities, spanning
different continents. Such diversification of import
sources is largely driven by cost-effectiveness in a
competitive global market. This study provides valuable
insights into India’s import dynamics and trade partnerships on these key agricultural commodities used
by the feed industries (as well as some food industries),
thereby offering essential information for the feed industry, commodity traders and policymakers.

Keywords: Angiogenesis, collagen, diabetes mellitus, growth factor, remodelling, ulcers, wounds.
Abstract: Diabetes is a diverse metabolic disease that is caused
by increased levels of blood glucose, which also leads to
the generation of several other complications. The formation of wounds and their delayed healing are among
the main areas of concern. Wound repair is a process,
which replaces damaged cells with healthy cells; it
generally occurs in four steps – haemostasis, inflammation, proliferation and remodelling. This review covers
the causes of diabetes mellitus, its prevalence, its impact
on wound healing, different types of wounds and their
management. Diabetes mellitus impairs wound healing
through several mechanisms such as impaired angiogenesis, altered collagen production, etc.

Subject: When 2023 is the International millet year, are healthcare professionals aware about millets?
Keywords: Global health, healthcare, nutrition, therapeutic foods, traditional diet, SDG 3, year of millets.
Abstract: Millets are smart foods that have noteworthy nutritional and therapeutic benefits. Regular consumption
of millets is beneficial as it manages postprandial glucose levels, lowers insulin resistance, positively
affects HbA1c, reduces the risk of atherosclerotic changes and cardiovascular disease, lowers LDL
and improves hypertension. The Government of India has taken a lead role in launching strategies
for the promotion of millets to make India a global hub. Stakeholders associated with healthcare
play a major role in advising millet-based diets. The present article of a questionnaire-based survey
brings an analysis of knowledge, attitude and practices of healthcare professionals in our university
regarding millet consumption. It is observed that a sizable number of participants (62%) could identify different types of millets; 66.4% of participants routinely consumed millet foods since childhood;
54% wish that it should be a part of therapeutic diet recommendation, but most of the participants
are not completely aware of the therapeutic benefits of millets.

Subject: An emerging groundwater crisis in parts of Chhattisgarh state, India
Keywords: None
Abstract: Chhattisgarh is an agrarian state, with
about 80% of the state’s population working
in agriculture and allied fields. Paddy is the
principal crop, and the central plains of the
state are known as the rice bowl of central
India. Around 33% of the area of the state
is under cultivation. The net sown area in
2022 in the state was 4.63 million hectares,
with irrigation facilities in ~45% of the area1
.
Multiple cropping seasons are practiced in
about 23% of the net sown area. Groundwater forms a significant component of irrigation water, and an average of 84% of the
entire draft is used for this purpose in the
state2
. The use of bore wells (BWs) for
groundwater irrigation in the state has witnessed a nine-fold increase during the last
30 years3
. This has caused an overall increase in groundwater development from
3.31% in 1990 to 47.2% in 2023. As per
the recent estimations2
, out of the total 146
assessment units (blocks), there are 5 units
in ‘critical’ and 22 in ‘semi-critical’ categories (with groundwater extraction >90%
and between 70% and 90% of the annual recharge of the aquifer respectively). Consequently, depletion in water levels is being
reported across the state4
. It is pertinent to
note here that the water levels in several parts of the country have declined to unsustainable levels5 owing to uncontrolled
groundwater extraction for irrigation and
other uses6
. The decline in water level may
lead to several adverse impacts (other than
reduction in freshwater availability and increase in pumping cost), such as drying
up/reduction in flow/storage in surface water bodies/streams, drying up/shrinkage of
wetlands, land subsidence and further reduction in aquifer storage, reduction/
elimination of vegetation, deterioration in
groundwater quality, etc.

Abstract: Planarians have a remarkable ability to regenerate lost body parts, including the brain, auricle, eye spots, etc.
They have been excellent model systems for pharmaceutical studies, including regenerative medicine, toxicology
and drug testing. An overview of currently available planarian model species used for studying the effects of
contaminants and pharmaceuticals on regeneration is important for initiating studies in laboratories for the
first time and developing indigenous model species. The present study provides a list of currently used planarian
model species around the globe and in India. The analysis highlights the lack of taxonomic studies providing
accurate identification of planarian species in India and unavailability of indigenous model species.

Whatever system we had to detect, the Cisco Grafters, were within India and the tsunami genic zones were Indonesia and the Andaman coast, which are outside Indian mainland. In order to detect, you need to pinpoint correctly, for which you need a system on both the sides of the earthquake.

Abstract: Impact of rainfall and slopes on soil organic carbon
(SOC) dynamics was assessed under tea and coffee plantations, land covers, in Western Ghats Mountain (WGM).
Severe water erosion in the western side of WGM by
heavy rainfall and land sloppiness recorded less SOC
(3.07%) compared to the eastern side (4.03%) in tea plantations. Similar trend in SOC was observed in coffee
plantations, with 1.98% in western side and 3.25% in
eastern side. Loss of soil organic carbon stock under
tea plantations in western sides was 0.346 million tonnes
and in coffee plantations it was 0.190 million tonnes.
Hence, the total organic carbon loss was 0.536 million
tonnes. Highest SOC content and stocks were recorded
in steep slopes in tea and coffee plantations due to
dense biomass cover and adoption of soil and water
conservation measures

Abstract: Hastinapur is one of the prominent painted grey ware
archaeological sites in the Ganga Valley. In the present
communication, we report the results of the metallurgical analysis of the excavated slag samples from the
site. The existence of a large number of iron objects for
this site can be dated between c. 6th century BCE and c.
16th century CE, with early iron from the 8th century
BCE. The morphological, microstructural and elemental
studies of the excavated slag indicate a high amount of
carbon in iron, indicating crucible carburization activities at this site. In addition, the presence of niobium,
cobalt, etc. in the slag indicates the usage of non-traditional iron ores in the primary ironmaking stage.

was 72.6% reduction in FAW infestation and 57.6%
increase in the grain yield from the SpfrNPV NBAIR1-
treated plots during 2019 and 2020. It is concluded
that SpfrNPV NBAIR1 is a potential isolate to manage
the FAW infestation
