Published: June 2024

Abstract: This study employs machine learning techniques to assess global environmental health, focusing on air quality and water pollution. Through extensive data collection and preprocessing, including feature engineering, insights are extracted from diverse datasets encompassing pollutant concentrations, meteorological conditions, and socio-economic indicators. Machine learning algorithms, including LSTM models, are employed to analyze temporal dependencies and predict pollution levels. Additionally, clustering, regression analysis, and spatial analysis techniques aid in identifying pollution hotspots and trends. The proposed system integrates IoT technology for real-time data collection and Apache Spark for efficient processing. Evaluation metrics such as Mean Absolute Error and Root Mean Square Error assess model performance. The dataset comprises hourly averaged responses from chemical sensors deployed in a polluted area, complemented by ground truth data from a reference analyzer. This research contributes to informed decision-making for environmental management and sustainable development in smart city environments
An Overview on Several Types of the Optical Interferometers
Authors: Jalil Muhammad Arif Bin
Published: June 2024

Abstract: A common research instrument in many branches of science and engineering is the interferometer. Because they can identify and analyse interference patterns caused by the combination of light sources, these mid- to late-19th-century technologies are known as interferometers. The tool used for this process is called a "interferometer" or "interfere-meter." Interferometers are remarkably versatile devices that enable the development of highly accurate optical sensors for a wide range of applications. This article discussed the principles of interferometry as well as three different interferometer configurations. The chosen configuration will be influenced by the machinery, mechanical stability, laser coherence, and particular goals. Interferometers are widely used in lab-on-a-chip systems for non-invasive biomolecule research, astronomy, and gravitational wave detection.
The Effect of Check Dams and Changing Land Uses on the Productivity of Catchment Sediments in Yusmerg(Jammu and Kashmir)
Authors: Pandit Dr. Bashir Ahmad
Published: June 2024

Abstract: Reforestation and the cessation of agricultural activity have resulted in significant changes to land use in several parts of Jammu and Kashmir. on parallel, the Administration invests a significant amount of money on hydrological control projects to lessen silt transport and erosion. Nevertheless, it is still unknown how these significant changes in land use will impact catchment-scale erosion processes and whether effective hydrological control will lessen the export of silt. To assess the effects of land use scenarios with and without sediment control facilities (check-dams) on sediment yield at the catchment scale, a combination of field work, mapping, and modeling was employed. The study catchment is in Kashmir, where there have been significant changes in land use that have resulted in a decrease in agricultural area and an increase in forest cover. In addition, as part of the related reforestation efforts, numerous check-dams were built in the watershed.

Authors: Kushwah Rupesh , Gangotiya Somaya , Patil Kishor
Published: June 2024

Abstract: The integration of chemical admixtures and alternative materials in concrete production has become a focal point in advancing construction technologies. This study investigates the combined effects of superplasticizers and mill scale on the workability and compressive strength of M30 grade concrete. Three different superplasticizers—Auramix 200, SikaPlast®-3069 NS, and Master Polyheed 8126—are evaluated for their performance enhancements in concrete. Additionally, mill scale, an industrial by-product, is utilized to partially replace sand in varying proportions (0%, 20%, 40%, 60%, 80%, and 100%) to assess its viability as a sustainable aggregate alternative. The experimental phase is divided into three stages: initially assessing the workability and compressive strength of M30 concrete without admixtures; subsequently incorporating mill scale to observe its effect on concrete properties; and finally combining mill scale with each superplasticizer to maintain workability while evaluating the compressive strength. Slump cone tests are conducted to measure workability, and compressive strength tests are performed at 7, 14, and 28 days. Results indicate that the inclusion of superplasticizers significantly enhances workability, with Auramix 200 showing the highest improvement. The addition of mill scales up to 60% replacement level increases compressive strength, with a notable peak at 60% replacement for both plain and superplasticizer mixes. However, higher replacement levels (80% and 100%) result in reduced strength and workability. Among the superplasticizers, Auramix 200 exhibits the best overall performance in conjunction with mill scale. This study concludes that the strategic use of superplasticizers and mill scale can produce high-performance, sustainable concrete. Future research should explore long-term durability aspects and optimize mix designs for broader applications in construction.

Democracy is often hailed as a natural form of government, yet it is not a system that arises effortlessly. Many stereotypes, beginning with the entrenched notion that democracy embodies the rule of the people, do not align with historical and factual realities. Initially, democracy represented the rule of a relative minority possessing economic resources and political power. Athenian democracy, which initially thrived, was ultimately destroyed when it devolved into an ochlocracy driven by the unreasonable interests of the masses, a transformation brought about by the power struggles among demagogues. Political elites seeking to control governance have actively promoted democracy, incorporating various norms and rules into it to ensure their continued authority by persuading the masses. Given that many modern criticisms of democracy stem from these distortions, it is necessary to reevaluate them historically and logically to identify areas for correction.

Researchers have different opinions about the duration of election campaigns. Some scholars believe that the campaign period should be long enough because of the importance of voters' right to know, to make their choice, and for candidates to introduce themselves to voters. However, some researchers believe that too long campaign period has negative aspects such as annoying the voters, demanding more financial expenses from the candidates, and reducing government activities. According to the document research, countries around the world have implemented election campaign periods in different ways in the 20th century. Majority countries have a lead time of 30-50 days. It is common for the law to prohibit any advertising from 24 to 48 hours before election day.

Published: June 2024

The common form of palm sugar is usually in solid form and needs to be dissolved before use. To facilitate utilization, palm sugar is processed into liquid palm sugar. One of the issues encountered during the production of liquid palm sugar is the formation of foam, which can decrease the quality of the liquid palm sugar. Therefore, measures are needed to anticipate foam formation, including the addition of candlenut seeds and coconut oil. This study aims to determine the influence of the addition of candlenut seeds and coconut oil on the physical and chemical characteristics of liquid palm sugar, identify the optimal levels of candlenut seeds and coconut oil that meet the national standard (SNI) for liquid palm sugar, and produce a liquid palm sugar product preferred by consumers. The research employed a Randomized Complete Block Design (RCBD) with a single factor and six treatment levels of candlenut seeds and coconut oil (0%, 0.1%, 0.3%, 0.5%, 0.7%, and 0.9%). Data analysis was conducted using Analysis of Variance (ANOVA). Based on the research results, the addition of candlenut seeds and coconut oil significantly influenced the viscosity of liquid palm sugar but had no significant effect on its color and moisture content. The addition of candlenut seeds and coconut oil had a significant impact on the chemical quality of liquid palm sugar, affecting ash content and total insoluble solids but showing no significant effect on pH and total dissolved solids. The treatment with 0%, 0.1%, and 0.3% additions of candlenut seeds and coconut oil met the quality requirements for moisture content, while the ash content in the 0%, 0.1%, and 0.3% treatments also complied with the standards. The addition of 0.9% candlenut seeds and coconut oil resulted in liquid palm sugar that met both SNI standards and consumer preferences.

The cross-sectional survey design was used among 200 participants using the latest conversational GPT-4 AI model in their phones using the convenience sampling techniques. Hypothesis one results revealed there is a statistically significant between the usage of the conversational GPT-4 AI model and the incidence of cyber crime [R = .255, R2 = .065, [F (1,189) = 13.223, P< .01]. Hypothesis two showed that the baseline usage of the conversational GPT-4 AI model significantly predicts increase in social media addictions [R = .434, R2 = .188, [F (5,195) = 24.147, P<.01]. Hypothesis three revealed that the usage of conversational GPT-4 AI model is significantly associated with an increase in both cyber crime and social media addictions [R = .474, R2 = .226, [F (2,185) = 5.991; P<.01]. Based on this current study, there is need to develop and deliver educational programs aimed at informing residents and users about the responsible use of AI technologies, including those built on GPT-4 model.
Spatial, environmental, and functional distances among temporal ponds attenuate synchronization, stabilizing plant richness and biomass dynamics
Authors: Sosa-Panzera Lucía , Pinelli Verónica , Arim Matias
Published: June 2024

Growing evidence indicates that the tendency to synchronize community
dynamics may be a general phenomenon in nature related to metaecosystem
stability. Synchronized dynamics reduce stability since local variations
in biomass or richness are directly propagated to variations in
metacommunity dynamics. Asynchronous dynamics have a strong stabilizing
effect because of the cancelling out of local variations.
Synchronization of biodiversity dynamics may occur due to dispersal
among communities and similar responses of different communities to
correlated environmental variations—the generalized Moran effect. This
congruent response of different communities to environmental dynamics
depends on their similar functional composition, which is determined by
the similarity in local conditions and the spatial distance between
them. In a metacommunity of 51 temporary ponds that were surveyed for 14
years, we evaluated the existence of synchronized dynamics in plant
richness and biomass among communities, and their association with
temporal stability. A path analysis based on Mantel tests was used to
evaluate the hypothesized determinants of synchrony and stability.
Community-community matrices for Mantel tests were constructed with
synchrony in biomass and richness, and with the Euclidean distance in
geographic location, environmental conditions, and functional
composition. Elements of the stability matrices were the inverse of
variation in richness and biomass for each pair of ponds. A wide range
of dynamics from asynchronous to synchronous rhythms was observed, and
stability decreased with the coupling of community dynamics. Geographic,
environmental, and functional distances between pairs of communities
decoupled their dynamics in richness but weakly affected biomass
synchrony. The role of rare species in richness dynamics and of dominant
species in biomass dynamics may explain the observed discrepancies.
While evidence for biodiversity synchrony is accumulating, evaluating
the role of the proposed determinants becomes essential. Our results
support the main hypotheses but also identify discrepancies that may
devote further attention.

In developing nations such as Pakistan, mental health disorders are
common. The high incidence might be attributed, in part, to the
inadequate understanding of mental health concerns and the low literacy
rate. That might be the cause of Pakistan’s extremely low number of
psychiatrists. Pakistan has one of the lowest rates of psychiatrists in
the WHO Eastern Mediterranean Region and the entire globe, with only
0.19 per 100,000 people, according to the World Health Organization’s
statistics

Published: June 2024

Hofmeister effect is a famous physical chemistry phenomenon that was
reported a hundred years ago, which firstly refers to the action of
certain salts to decrease the solubility of proteins while others
increase. The Hofmeister effect on the luminescent properties of
cationic organic fluorophore is still obscure, especially for their room
temperature phosphorescence (RTP). Herein, hydrophilic groups
(quaternization pyridine) were introduced into carbazole molecules to
obtain a series of carbazole derivatives (named CZ-Py
) with different counter anions in the Hofmeister
series. These carbazole derivatives displayed tunable fluorescent color
from cyan to yellow in the solid state following the Hofmeister sequence
and anti-Hofmeister behavior in aqueous solution. Moreover, RTP material
with tunable emission color and lifetime was achieved by doping CZ-Py
with Hofmeister series anion in polymethyl
methacrylate (PMMA) and polyvinyl alcohol (PVA), which displayed good
performance in time getting information encryption and
anti-counterfeiting.
Exploring the interaction between Fe 3+ and REGLE motif of the high-affinity iron permease (Ftr1): an in silico approach
Authors: Choudhury Ahana Roy , Murali Ayaluru
Published: June 2024

Mucormycosis is an invasive fungal infection with considerably high
mortality rates in immunocompromised individuals. Due to COVID-19
pandemic, the disease has resurfaced recently and lack of appropriate
antifungals resulted in a poor outcome in patients. The iron uptake
mechanism in Rhizopus delemar, the predominant causal agent is
crucial for its survival and pathogenesis in human host. The current
study focuses on the structural dynamics of high affinity iron permease
(Ftr1) which act as a virulence factor in this fatal fungal disease.
Ftr1 is a transmembrane protein which is responsible for the transport
of Fe ion from the extracellular milieu to the
cytoplasm under iron-starving conditions in Rhizopus. In this
work, the three-dimensional modelling of Ftr1 was carried out and it was
found to possess seven transmembrane helices with N-terminal lying in
the extracellular region and C-terminal in the intracellular region.
Moreover, the present study delineates the interaction of glutamic acid
residues, found in the REGLE motif of the fourth transmembrane helix
with Fe . The molecular dynamics (MD) simulation
study revealed that the glycine present in the motif destabilizes the
helix thereby bringing E157 closer to the positively charged ion.
Understanding the interaction between Fe ion and
Ftr1 would be helpful in designing effective small molecule drugs
against this novel therapeutic target for treating mucormycosis.

Published: June 2024

The DprA protein has been implicated in the protection of
incoming DNA. However, the presence of dprA gene family members, also
known as smf, across diverse bacterial species suggests a broader
functionality for their gene products. We examined the role of the
Escherichia coli DprA/Smf homologue in conjugation. Remarkably,
Bacillus subtilis dprA/smf can complement an E. coli dprA mutant,
indicating interchangeability of dprA/smf genes between competent and
non-competent species in conjugational processes. The DprA protein forms
a complex with DNA, facilitating the nucleation of RecA protein
filaments onto circular single-stranded DNA coated with SSB protein. To
focus on RecA nucleation, we employed short DNA oligonucleotides that
restrict RecA-DNA binding but allow for DprA-RecA-DNA binding. Analysis
of dATPase activity revealed that RecA-DNA complexes were readily formed
only with olig50, while DprA-RecA-DNA complexes were also feasible with
olig21. Combining experimental data with a full-atomic model of the
RecA-DprA-ssDNA complex’s spatial structure, we proposed a molecular
mechanism for DprA-mediated loading of RecA proteins onto ssDNA. Our
findings suggest that only one DprA-ssDNA interaction can occur
sterically, occupying one strand of ssDNA in the complex.

Published: June 2024

AbstractObjectives: Worldwide, the neonatal age group
bears high mortality risk that is attributed to diverse causes. In
Palestine, there is a scarcity of studies investigating the determinants
of neonatal deaths. Through this research, we investigated the level of
mothers’ knowledge and awareness in recognizing neonatal danger signs
(NDS) and associated factors. Hypothesis: There is no difference
in mothers’ knowledge regarding NDS with regard to diverse
socio-demographic characteristics and reproductive factors including
antenatal and postnatal care. Methodology: A community-based
descriptive cross-sectional study was conducted among 377 mothers who
gave birth in the last year and attended primary care centers for child
vaccination in Ramallah and Jerusalem Governance from December 2023 to
January 2024. This was done using structured questionnaires completed
through face-to-face interviews covering socio-demographic variables,
mothers’ reproductive history, and NDS knowledge assessment.
Results: Among the 377 mothers, only 51% had good knowledge,
reporting at least three danger signs. The most frequently mentioned
were difficulty breathing (73.21) and fever (64.72%), while hypothermia
(2.65%) and convulsions (11.67%) were the least mentioned. Statistical
analysis indicated that having a national health insurance card (
p=0.002) and an educated husband ( p=0.020) are
significantly associated with mothers’ knowledge of NDS. These factors
could potentially be important to consider in intervention and
educational programs aimed at improving mothers’ knowledge.
Conclusion: This study showed that mothers’ knowledge of NDS is
relatively low, impacting public health in Palestine as in other
developing countries. Therefore, collective efforts are needed to
educate mothers on the importance of early NDS identification.
The present is more important than the past: associations between developmental stability, canalization and phenotypic plasticity in response to heterogeneous experience
Authors: Wang Shu , Callaway Ragan M.
Published: June 2024

The relationships among developmental stability, canalization and
phenotypic plasticity are not straightforward, but may be better
understood in the context of temporally heterogeneous environments. Our
objective was to investigate the effects of early experience with
temporally heterogeneous water availability on the associations between
developmental stability, canalization and phenotypic plasticity. We
subjected eight plant species to a first round of alternating inundation
and drought vs. constantly moderate water treatments and a second round
of water conditions. Fluctuating asymmetry (FA), intra- and
inter-individual variation (CVintra and CVinter), and plasticity in
traits were measured and correlations between variables were calculated
for each species. Early temporally heterogeneous experience decreased
the leaf size of half of the species, but had complex effects on leaf
fluctuating asymmetry (FA) and inter-individual variation (CVinter) in
traits immediately or in late conditions, with little effects on
intra-individual variation (CVintra). There were several positive
correlations between FA and CVinter, positive correlations between
CVinter and plasticity in early treatments, but negative correlations in
late treatments. Our results suggested complexity and variability in the
relationships between different mechanisms. Decreased canalization may
promote plastic responses in traits before or during the induction of
plasticity, whereas canalization may reflect phenotypic convergence
after plastic responses. Temporally heterogeneous experiences may
facilitate positive correlations or attenuate negative correlations
between decreased canalization and plasticity. We provide direct
evidence for relationships between developmental stability, canalization
and plasticity as well as the role of temporally heterogeneous
environments in modifying these processes. The integrative way that
plants deal with environmental variation demonstrates their ability to
evolve in multiple directions via many flexible adjustments in response
to varying environmental signals over a plant’s lifetime.

Donor and recipient HCMV-seropositive (D+R+) lung transplant recipients
(LTRs) often harbour multiple human cytomegalovirus (HCMV) strains,
likely due to transmitted donor (D) strains and reactivated recipient
(R) strains. To date, the extent and timely occurrence of each likely
source in shaping the post-transplantation (post-Tx) strain population
is unknown. Here, we deciphered the D and R origin of the post-Tx HCMV
strain composition in blood, bronchoalveolar lavage (BAL), and CD45+ BAL
cell subsets. We investigated either D and/or R formalin-fixed
paraffin-embedded blocks or fresh D lung tissue from four D+R+ LTRs
obtained prior to transplantation. HCMV strains were characterised by
short amplicon deep sequencing. In two LTRs, we show that the
transplanted lung is reseeded by R strains within the first six months
after transplantation, likely by infiltrating CD14+ CD163+/- alveolar
macrophages. In three LTRs, we demonstrate both rapid D-strain
dissemination and persistence in the transplanted lung for
>1 year post-Tx. Broad inter-host diversity contrasts with
intra-host genotype sequence stability upon transmission, during
follow-up and across compartments. In D+R+ LTRs, HCMV strains of both, D
and R origin can emerge first and dominate long‑term in subsequent
episodes of infection, suggesting no replication advantage of one source
over the other despite pre-existing R strain-specific immunity.
Effect of Bed Clay on Surface-Water Wave Reconstruction from Ripples

Published: June 2024

Wave ripples can provide valuable information on their formative
hydrodynamic conditions in past subaqueous environments by inverting
dimension predictors. However, these inversions do not usually take the
mixed non-cohesive/cohesive nature of sediment beds into account. Recent
experiments involving sand–kaolinite mixtures have demonstrated that
wave-ripple dimensions and the threshold of motion are affected by bed
clay content. Here, a clean-sand method to determine wave climate from
orbital ripple wavelength has been adapted to include the effect of clay
and a consistent shear-stress threshold parameterisation. From
present-day examples with known wave conditions, the results show that
the largest clay effect occurs for coarse sand with median grain
diameters over 0.45 mm. For a 7.4% volumetric clay concentration, the
range of possible water-surface wavelengths and water depths can be
reduced significantly, by factors of three and four compared to clean
sand, indicating that neglecting clay when present will underestimate
the wave climate.
