Wind Farm Layout Optimization Subject to Cable Cost, Hub Height, and a Feasible 3D Gaussian Wake Model Implementation
Authors: Croonenbroeck Carsten , Hennecke David
Published: March 2024

We address the Wind Farm Layout Optimization (WFLO) problem and tackle the optimal placement of several turbines within a specific (wind farm) area by incorporating additional aspects of an economically driven target function. With this, we contribute three refinements for WFLO research: First, while many research contributions optimize the turbines’ locations subject to maximum energy production or energy efficiency, we instead pursue a strategy of maximizing a profit objective. This enables us to incorporate inner-farm wiring costs (underground cable installation). For this, we explore the impact of using MSTs (Minimum Spanning Trees) and adding junction (so-called “Steiner”) points to the terrain plane. Second, while most research focuses on finding optimal x and y coordinates (i.e., address two-dimensional turbine placement), we also optimize the turbines’ hub heights z. Third, we also provide a software implementation of the Gaussian wake model. The latter finds entrance to the open-source WFLO research framework that comes as package wflo for statistical software R. We find that taking wiring cost into account may lead to very different turbine placements, however, increasing overall profit significantly. Allowing the optimizer to vary the hub heights may have an ambiguous impact on the wind farm profit.

La producción de fruta es permanente, a través de todo el año, con épocas marcadas de concentración de la cosecha, según sea la distribución de la precipitación, unimodal o bimodal, características de la zona Andina. Con base a la producción constante a través del año y la dinámica poblacional de los insectos, el manejo fitosanitario de la producción se hace compleja, por el manejo del cultivo y la aparición de insectos plagas emergentes. La presencia de un nuevo insecto asociado al cultivo de los cítricos, hace que se genere un reporte y se profundice en la investigación.
Machine Learning for Prediction of Tuberculosis Detection: Case Study of Trained African Giant Pouched Rats
Authors: Jonathan Joan , Barakabitze Alcardo Alex , Fast Cynthia D , Cox Christophe
Published: March 2024

Background

Technological advancement has led to the growth and rapid increase of tuberculosis (TB) medical data generated from different health care areas, including diagnosis. Prioritizing better adoption and acceptance of innovative diagnostic technology to reduce the spread of TB significantly benefits developing countries. Trained TB-detection rats are used in Tanzania and Ethiopia for operational research to complement other TB diagnostic tools. This technology has increased new TB case detection owing to its speed, cost-effectiveness, and sensitivity.

Objective

During the TB detection process, rats produce vast amounts of data, providing an opportunity to identify interesting patterns that influence TB detection performance. This study aimed to develop models that predict if the rat will hit (indicate the presence of TB within) the sample or not using machine learning (ML) techniques. The goal was to improve the diagnostic accuracy and performance of TB detection involving rats.

Methods

APOPO (Anti-Persoonsmijnen Ontmijnende Product Ontwikkeling) Center in Morogoro provided data for this study from 2012 to 2019, and 366,441 observations were used to build predictive models using ML techniques, including decision tree, random forest, naïve Bayes, support vector machine, and k-nearest neighbor, by incorporating a variety of variables, such as the diagnostic results from partner health clinics using methods endorsed by the World Health Organization (WHO).

Results

The support vector machine technique yielded the highest accuracy of 83.39% for prediction compared to other ML techniques used. Furthermore, this study found that the inclusion of variables related to whether the sample contained TB or not increased the performance accuracy of the predictive model.

Conclusions

The inclusion of variables related to the diagnostic results of TB samples may improve the detection performance of the trained rats. The study results may be of importance to TB-detection rat trainers and TB decision-makers as the results may prompt them to take action to maintain the usefulness of the technology and increase the TB detection performance of trained rats.
Validating the Effectiveness of the Patient-Centered Cancer Care Framework by Assessing the Impact of Work System Factors on Patient-Centered Care and Quality of Care: Interview Study With Newly Diagnosed Cancer Patients
Authors: Elkefi Safa , Asan Onur
Published: March 2024

Background

Patients with cancer who have recently been diagnosed have distinct requirements compared to cancer survivors. It is crucial to take into account their unique needs to ensure that they make informed decisions and are receptive to the care provided.

Objective

This study suggested a framework titled Effectiveness of Patient-Centered Cancer Care that considers the needs of newly diagnosed patients with cancer and related work system factors. This study investigated how work system factors influence the perceptions of patient-centered care, quality of care, and associated outcomes among newly diagnosed patients with cancer. Patient-centered care is defined in terms of workload and communication considerations, whereas the quality of care is assessed through indicators such as trust in physicians, satisfaction with care, and perceptions of technology.

Methods

This study used qualitative data collected through interviews with newly diagnosed patients with cancer (N=20) right after their first visits with their physicians. Thematic analysis was conducted to validate the 5 hypotheses of the framework, mapping the interactions among quality of care, patient-centered care, and work system factors.

Results

We found that workload and patient-centered communication impact the quality of care and that the work system elements impact the patient-centeredness (workload and communication) and the quality of care (trust in physicians, satisfaction with care, and perception of technology use).

Conclusions

Qualitatively validating the proposed Effectiveness of Patient-Centered Cancer Care framework, this study demonstrated its efficacy in elucidating the interplay of various factors. The framework holds promise for informing interventions geared toward enhancing patients’ experiences during their initial visits after diagnosis. There is a pressing need for heightened attention to the organizational design, patient processes, and collaborative efforts among diverse stakeholders and providers to optimize the overall patient experience.
Promoting Return to Work After Vocational Rehabilitation Using a Work-Related Fitness App: Protocol for a Cluster-Randomized Controlled Trial (Preprint)
Authors: Bühne David , Elling Jan Mathis , Hetzel Christian , Alles Torsten
Published: March 2024

BACKGROUND

Retraining programs in vocational rehabilitation are often characterized by a low level of physical activity, even when targeting jobs with primarily physical demands. They might therefore be accompanied by a decline in functional capacity if the lack of physical activity is not compensated by increased activity during leisure time. The implementation of a work-related exercise app might be a promising approach to promoting a return to work in vocational rehabilitation. We developed the “WORKout-app” which provides exercise plans based on a comparison of the physical demands of the retraining profession and the current functional capacity.

OBJECTIVE

The aim of this study is to examine the effects of app-based exercise during vocational rehabilitation on perceived work ability (primary outcome), occupational self-efficacy, days of sick leave, and return to work (secondary outcomes).

METHODS

We conducted a cluster-randomized controlled trial with 2 arms (intervention: WORKout-app vs control: treatment as usual) in 4 cohorts of 5 vocational rehabilitation centers in Germany. Participants are nested within retraining classes per vocational rehabilitation center and per cohort assigned to either the intervention condition or the control condition. The target sample size at the participant level is 598. Measurement time points include baseline, the end of rehabilitation, 3 months after the end of rehabilitation, and 6 months after the end of rehabilitation. Linear and generalized linear mixed-effects models are performed to test for treatment differences in outcomes.

RESULTS

This study is funded by the German Federal Pension Insurance. The trial is registered with the German Clinical Trials Register (DRKS00030775) and approved by the Ethics Committee of the German Sport University Cologne (145/2022).

CONCLUSIONS

The findings of the study will inform researchers and practitioners about the effectiveness of an exercise app developed to counteract the effects of physical inactivity during vocational rehabilitation.

Banned Tracking Technology Use Among Medical Device, Pharmacy, and Hospital Webforms: A Cross-Sectional Study (Preprint)
Authors: Downing Andrea , Holdren Jill
Published: March 2024

BACKGROUND

Tracking technologies are frequently employed to gather and examine data regarding user interactions with websites or mobile applications of regulated health-related entities. These technologies then illegally share user data with third parties that use it to target ads to patients across social media platforms. This collection and sharing constitutes a data leak of massive proportions. Specifically, some pharmacies, medical device companies, and hospitals utilize banned tracking or surveillance technologies on their websites in a way that exposes patients’ prescriptions, medical device information, doctor appointments and contact details to third parties.

OBJECTIVE

This study aimed to assess the use of prohibited tracking technologies on unauthenticated URL’s within three types of entities: pharmacies, medical companies, and health systems.

METHODS

We identified the largest-by-revenue medical device companies, pharmacies, and hospitals in the United States, using a scanning tool we developed based on existing open source software to detect the presence or absence of five banned tracking technologies on a sample of them.

RESULTS

In total, we included 341 URLs associated with three different types of HIPAA covered entities in our scan sample. Medical device company (n= 147) webpages comprised 43.1% of our overall sample. Pharmacy webpages (n=96) comprised 28.2% of our sample, and hospitals/health system URLs (n=98) comprised 28.7% of our sample. 63.9% of the medical device company URLs scanned contained at least one banned surveillance technology. 59.2% of pharmacy URLs scanned had at least one banned surveillance technology installed. 59.8% out of hospital URLs scanned contained at least one banned surveillance tracker.

The most common tracker found on medical device company sample was Google Audience (39.5%), followed closely by Facebook Pixel (36.1%)

There were a number of device companies, pharmacies, and hospitals scanned that had none of the banned trackers. n=53 URLs or 36.1% did not have any banned trackers identified. 40.8% (44) of pharmacies did not have any trackers. 67.0% of hospital URLs scanned did not have any trackers identified.

CONCLUSIONS

This study demonstrates the presence of health trackers on many health-related sites despite the laws that prohibit them, and further examines the ways PHI may be shared with social media platforms or third parties via unauthenticated landing pages. Future studies are needed to assess the impact of leaking sensitive data belonging to millions of patients to third party vendors.

Data Disaggregation in Action: Filipino Americans Who Do Not Identify As Asian (Preprint)
Authors: Shimkhada Riti , Juhnke Andrew , Ponce Ninez
Published: March 2024

BACKGROUND

While the U.S. Office of Management and Budget (OMB) places Filipino Americans under the Asian category, some Filipino Americans may not identify as Asian and opt to identify as “other” or as Pacific Islander (PI).

OBJECTIVE

We examine here the extent to which Filipino Americans choose Pacific Islander or “other” instead of Asian using a large population-based survey of Californians.

METHODS

This study used data from the 2019, 2020, and 2021 rounds of the California Health Interview Survey (CHIS), the largest state health survey in the United States, and one of the few data systems that includes write-in prompts for the collection of detailed race data. The study focused on participants who identified as Pacific Islanders and wrote-in 'Filipino,' those who selected 'Asian' and specified 'Filipino,' and respondents who selected 'other' and wrote-in 'Filipino' for their detailed race group.

RESULTS

Our analysis included 1,859 Filipino respondents of which 8.77% identified as Pacific Islander, 85.15% as Asian, and 6.08% as "other." Those who identified as PI tended to also identify as Latino/Hispanic, be older, and have U.S. citizenship compared to those who identified as Asian.

CONCLUSIONS

We recommend the inclusion of open-ended prompts in health surveys and the disaggregation of Filipino Americans from the general Asian category. We posit expanded data collection standards and region-based classifications for Asian subgroups can better capture the full extent of the diversity of the aggregate group. Further community-driven research is needed to address the specific health needs of Filipino Americans

Evaluating effective interventions for the provision of PrEP for Black women: A systematic review (Preprint)
Authors: McCoy Katryna , Gorman Brianna , Harris Ryan
Published: March 2024

BACKGROUND

HIV pre-exposure prophylaxis (PrEP) is an effective strategy to reduce the risk for acquiring HIV up to 99%. However, HIV incidence among Black cisgender women in the southern United States remains high. Behavioral interventions to improve PrEP uptake often focus on men that have sex with men. Examining the degree to which Black cisgender women have engaged in PrEP interventional studies, and the effectiveness of the existing PrEP interventions will inform HIV prevention strategies tailored for Black cisgender women.

OBJECTIVE

The purpose of this review is to assess and synthesize the current literature related to behavioral interventions that address uptake of PrEP as a strategy to reduce HIV incidence among Black cisgender women living in the southern US. We will also identify potential implement strategies to improve the engagement of Black cisgender women in the HIV-PrEP continuum.

METHODS

An expert librarian used Covidence software to screen behavioral interventions that included the uptake of PrEP as an outcome to reduce HIV incidence among Black cisgender women in the southern US. An expert librarian conducted a comprehensive search of peer-reviewed articles using APA PsycInfo, CINAHL Complete, Cochrane Library, PubMed, Sociological Abstracts and Web of Science. Search terms included: Black, woman, PrEP, and intervention. The initial search identified 738 relevant study titles. After deduplication and the screening process, 26 peer-reviewed, full-text articles were retrieved, among which five met our inclusion criteria, and were included in the final analysis guided by the social-ecological framework.

RESULTS

APA PsycInfo (n=85), CINAHL Complete (n=181), Cochrane Library (n=43), PubMed (n=214), Sociological Abstracts (n=7) and Web of Science (n=208). Two of the articles targeted the individual level, while one article was cited for each of the interpersonal, organizational, and community levels; no articles were targeted for the policy/societal level. Though there was inconsistency in measures of uptake of PrEP across the studies, tailored case management, same-day PrEP modalities, and the emphasis on motivational interviewing were determined to be the most effective strategies for promoting uptake of PrEP among Black women. Studies with a focus on case management had the greatest impact on PrEP uptake among Black women with more than two-thirds of the women in the same-day PrEP intervention filling PrEP prescriptions and one-third of the women taking PrEP by the second session in the MI-PrEP intervention.

CONCLUSIONS

The findings from this review imply that increased funding, low-barrier access to PrEP prescriptions, and developing interventions that address social determinants of health may improve Black women’s access to PrEP. This review provides a cross-sectional outlook of the limited quantity and heterogeneity in interventions and measures currently employed to assess the uptake of PrEP among Black women.

Authors: Ojo Idowu
Published: March 2024

Marketing communication is a management strategy that adopts the use of public relations, advertisement, sales promotion, personal selling, social media, web ads, direct marketing and oral communication as a tool for reaching out to her target audience thus the globally increasing competition in the hospitality operations. The study however examined the impacts of marketing communication and the impact of the social media marketing strategy on the performance of the hospitality industry in Ondo State. Some hotels were selected in respects of hotel ratings where patronage, number of rooms, services and facilities provided remained the yardstick for selection and five hotels were chosen from the State capital, Akure, Ondo State. The study adopted quantitative research. A total of 100 questionnaires were distributed to respondents and 85 questionnaires were retrieved. The results obtained showed overall mean score of 3.70 indicating that marketing communication enhances the performance of hospitality industry and data further showed that the R-value is 0.376a, this indicates that there is a minimum or insignificant relationship between social media and the performance of the hospitality industry with a small amount of 46.6% while the value of R square is 0.141 suggesting that social media has little influence in the amount of 24.3% on the performance of the hospitality industry in the study area. The study concluded that marketing communication plays a major role in the performance of the hospitality industry. The Study recommends that the management of the hospitality industry should devise a policy of marketing communication.

Authors: Sofyan Afriyadi , Hidayah Nur , Wiyono Bambang Budi , Ramli M.
Published: March 2024

Professionalization efforts for school counselors through professional education, which are strengthened by supervision during the educational process, aim to improve their clinical and multicultural competence, which is essential in providing guidance and counseling services in schools. Using a quantitative approach and the Supervision Outcome Scale analyzed using the Rasch model, this study examined supervision conducted by university and field supervisors of internship counselors. The results showed that supervision outcomes were in the moderate category in competency development. However, a closer look revealed variations in the level of difficulty of item agreement based on supervisors' perspectives. The study also highlighted challenges in achieving maximum supervision outcomes, including limited internship time. While this study provides important insights into supervision outcomes, limitations such as using a quantitative approach may only partially capture the complexity of the supervision process. Recommendations for future research include using qualitative methods, exploring other factors that reveal supervision outcomes, and researching the impact of internship duration on counselor competency development.

Published: March 2024

Although variable diet approaches shaped the gut bacterial abundance differently, they are considered the core factors in modulating gut microbiota throughdifferent mechanisms. Our aim in this study is to focus on the dietary candidates that could maintain a healthy gut microbiota by promoting commensal bacteria and reducingor inhibiting pathogens. In the current study, our objective is to demonstrate that a novel combined dietary approach of pre-and probiotic mixtures could be more effectivein inducing significant improvements in gut bacterial composition as a target to treat ASD. Luteolin complex veggie capsules (Swanson, USA), artichoke extract, as well asyogurt and Lactobacillus rhamnosus veggie capsules (5 billion CFU) (Swanson, USA), recently known as Lacticaseibacillus rhamnosus were selected as prebiotics and probioticsrespectively and were screened for their protective and therapeutic effects on the gut microbiota. They were all administered orally over 5 weeks to propionic acid PPAtreatedrats as rodent models of Autism (groups 4-10). Their results were compared to the control animal group undertaking a standard diet (group 1) and to post and pre-PPA-treated groups (groups 2 and 3). Lactobacillus and Bifidobacterium were noted as the most dominant, non-fluctuating strains in response to all diet intakes, and theynegatively influenced the presence of Proteobacteria (Enterobacteriaceae), which decreased in almost all treated groups during weeks 2 and 3, and 4.Interestingly, Clostridiumsp. was observed to be high in number at week 1, mainly in the control group (1) and pre and post-PPA groups (2 and 3), but were inhibited in all treated groups over theextended treatment period. Bacteroidetes were positively increased with the high presence of Lactobacillus and Bifidobacterium spp. Levels throughout the experiment in almostall animal groups. Thus, both prebiotics and probiotics study designed candidates (Luteolin complex capsules, artichoke extract, yogurt, and L. rhamnosus capsules) inhibitedClostridium sp., promoted commensal bacteria, specifically Lactobacillus and Bifidobacterium spp., restored the normal gut bacterial niches and therefore could be consideredas potential promising dietary approaches for maintaining healthy physical and microbial gut strategies.

The distribution of malaria is characterised by microgeographic variations determined by a range of factors, including the local environment. A study on the spatial distribution of malaria about land cover patterns was carried out by sampling Primary Health Centres in Ogoni Land. Nine Primary Healthcare Centres (PHCs) were selected across four local government areas (LGA) using Systematic Grid Point Sampling. Human blood samples were obtained from 318 consented individuals, and questionnaires were administered to obtain demographic data. Plasmodium species were identified through microscopy using thick and thin blood films. A geodatabase was created and imported into ArcGIS 10.7 to produce a thematic map of the study area. A cloud-free Landsat-8 Operational Land Imager (OLI) was employed for land cover analysis. Both supervised and unsupervised classifications of land cover were performed to generate the land cover classes. Pearson correlation was carried out to determine the significance between malaria distribution and land cover. Of the 318 individuals, 169 were infected with an overall prevalence of 53.1%.Only P. falciparum was identified and malaria distribution showed spatial variations. Across the PHCs sampled, the highest point prevalence was recorded in Model Primary Health Centre Koroma in Tai LGA whereas the lowest was recorded in MPHC Okwale in Khana LGA. Cumulatively, Kwawa PHC recorded the highest malaria prevalence whereas MPHC Bunu in Tai recorded the lowest prevalence. The highest prevalence was recorded in Khana LGA while the lowest was recorded in Eleme LGA. Land cover analysis revealed that Ogoni Land has a total land cover mass of 982.97km.2 Sparse vegetation dominated the study area (471.06km2) while dense vegetation covers a total mass of 213.1km2. Bivariate analysis showed a significant correlation between malaria prevalence and dense vegetation (p<0.05, 0.952). Dense vegetation played a significant role in malaria transmission in Ogoni Land. The study concludes that the presence of dense vegetation is associated with high malaria prevalence in the study area.
A COMPUTATIONAL DENSITY FUNCTIONAL THEORY INVESTIGATION OF THE INTERACTION OF BORON NITRIDE NANOSHEETS WITH MULTIPLE MOLECULAR HYDROGENS

Published: March 2024

In this study, the adsorption of molecular hydrogens (H2) on boron nitride (BN) frameworks was investigated using the density functional theory (DFT) technique. The results of optimized geometric structures revealed that molecular hydrogens were favourably adsorbed on top of nitrogen atoms in the BN monolayers. In addition, the optimized equilibrium geometries were utilized to calculate the electronic structures, including binding energies, energies of the highest and lowest occupied molecular orbitals (HOMO and LUMO), molecular electrostatic potentials (MEPs), and Mulliken atomic charges (MACs). The binding energy values were calculated to be approximately 0.01 eV per molecular hydrogen based on the results. As the number of molecular hydrogens increased in the BN framework, a slight increase was observed in the binding energy value per hydrogen molecule. Furthermore, the HOMO–LUMO gaps were determined with the corresponding energy values of about 6 eV. Regarding the Frontier molecular orbitals (FMOs) diagrams, the electron densities for the HOMOs of the studied systems were primarily focused on the N-edges. Conversely, for the LUMO, the electron density distribution was localized in the B-edges of titled systems. In the context of hydrogen adsorption on BN nanosheets, the MEP maps indicated that hydrogen atoms at the N-edges of the studied systems exhibited the most positive electrostatic potentials in this research. In contrast, surfaces with negative electrostatic potential surfaces were situated in the region close to B-edges. The computed results are consistent with the corresponding Mulliken atomic charge distributions. From the analyses of the Mulliken scheme, all nitrogen atoms displayed negative charge values, and positive charges were found on the boron atoms.

Period poverty is the inability of menstruators to have access to
all they need for proper handling of their menstruation which includes;
access to menstrual products, proper menstrual education and sanitary
facilities. It is a big threat, especially in low and middle-income
countries if not properly addressed and a hindrance to the achievement
of sustainable development goals. Period poverty has resulted in girls
missing classes due to lack of access to menstrual products. Also some
women and girls tend to use pieces of clothing, tissues and other
unhygienic material for the management of their menstruation due to
their inability to afford disposable pads. The hike in price of
disposable pads has made them a luxury for many girls to have especially
in low and middle-income countries. The amount of waste generated by the
use of these products is alarming and detrimental to the ecosystem.
There is a need to have a menstrual product that is affordable and
eco-friendly; reusable pads fit into this description. The issue of
whether menstruators would welcome the use of reusable pads due to fear
of being laughed at or believe that reusable pads can lead to infections
manifests as a result of a lack of proper education concerning these
products. Studies prove that reusable pads are not associated with any
form of infection and could be a better alternative to disposable pads.
This paper aims to emphasize on the important role the use of reusable
pads can play towards ending period poverty with prioritizing adequate
menstrual health education and improved water, sanitation and hygiene
facilities.

Published: March 2024

This tutorial focuses on standardised mean differences (SMD) as effect
measures in meta-analyses. We will explain what they are, when they
should be used, how to correctly compute and interpret them, and some of
the most common error made within evidence synthesis
Numerical Integration
Authors: Fantaye Abayneh Kebede
Published: March 2024

The function y=f(x)  is represented as an interpolated function and then
integrated between the provided limits to solve numerical integration.
It can be used to discover the anti-derivative of an integrand that
cannot be expressed in simple form, as well as to provide an estimated
solution for a definite integral that cannot be solved analytically.
When the function y=f(x) is not known directly, the numerical value of
the definite integral ∫a ^b f(x)dx is solved in this study. Finally,
we’ll look at the quadrature formula, which includes the Trapezoidal
rule, Simpson’s rules, Weddle rule, Boole rule, and Romberg’s
integration.
Bering Strait Ocean Heat Transport Drives Decadal Arctic Variability in a High-Resolution Climate Model

Published: March 2024

We investigate the role of ocean heat transport (OHT) in driving the
decadal variability of the Arctic climate by analyzing the
pre-industrial control simulation of a high-resolution climate model.
While the OHT variability at 65˚N is greater in the Atlantic, we find
that the decadal variability of Arctic-wide surface temperature and sea
ice area is much better correlated with Bering Strait OHT than Atlantic
OHT. In particular, decadal Bering Strait OHT variability causes
significant changes in local sea ice cover and air-sea heat fluxes,
which are amplified by shortwave feedbacks. These heat flux anomalies
are regionally balanced by longwave radiation at the top of the
atmosphere, without compensation by atmospheric heat transport (Bjerknes
compensation). The sensitivity of the Arctic to changes in OHT may thus
rely on an accurate representation of the heat transport through the
Bering Strait, which is difficult to resolve in coarse-resolution ocean
models.

Published: March 2024

This experiment was conducted to determine the effects of gestational
maternal under-nutrition on morphometric dynamics in rabbit fetuses.
Adult pregnant healthy female rabbits (n= 40) were divided into
under-nourished (UNG) and well-nourished (WNG) groups. Pregnant animals,
from every group (n= 5), were sacrificed, at weekly time intervals
(second week, third week, fourth week, and parturition). The least fetal
weight was found in UNG fetuses at 2 week (6.76±0.86
g) of pregnancy and highest in WNG fetuses at birth (43.16±0.77 g). The
minimum (0.05±0.007 g) and maximum (0.42±0.007 g) mean fetal heart
weights were found in UNG fetuses at 2 week and WNG
fetuses at birth, respectively. The lowest fetal heart length
(1719.3±181.39 um) and width (864.6±151.23 um) were found in UNG fetuses
at 2 week of pregnancy and the highest
(8241.4±107.31 um, 6510.7±83.47 um) in WNG fetuses at birth,
respectively. The lowest thoraco-abdominal length was recorded in UNG
fetuses at 2 week of pregnancy (2.26±0.07 cm) and
highest in WNG fetuses at birth (5.41±0.08 cm). The lowest biparietal
diameter was recorded in UNG fetuses at 2 week of
development (0.53±0.01 cm) and highest in WNG fetuses at birth
(1.89±0.01 cm). The lowest mean value of crown rump length was
observed in UNG fetuses at 2 week of development
(4.41±0.17 cm), and highest in WNG fetuses at birth (9.73±0.15 cm). In
conclusion, maternal undernutrition and developmental age significantly
affected the morphometric parameters. Maternal undernutrition had an
adverse effect while developmental age increased the morphometric
values.

Published: March 2024

This paper describes a catalogue of simultaneous observations of the
Earth’s magnetosheath by ESA’s Cluster and NASA’s MMS missions. The
catalogue is built from a visual inspection of summary plots provided by
the two missions complemented by an analysis of high-resolution magnetic
field data. The catalogue includes 117 events when Cluster 4 and MMS 4
crossed simultaneously the magnetosheath between January-April,
2017-2021. We also determine the bow shock geometry for each event based
on two different approaches: a) a minimum variance analysis of in-situ
magnetic field measurements, and b) a geometrical approach which
considers a bow shock model parameterized by OMNI data. A description of
spacecraft trajectory during each event is also provided. Additional
data describe the relative distances between Cluster 4 and MMS 4, a
classification of each event as either quasi-parallel or
quasi-perpendicular, and the distribution of events per magnetospheric
flank. The time intervals for the Cluster - MMS conjunctions included in
the catalogue, as well as all associated figures and tables discussed in
this paper are made available through an independent online data
repository, and can be freely downloaded and used by any interested
researcher.
The Physics of the Carbon Cycle: About the Origin of CO2 in the Atmosphere
Authors: Roth Eike
Published: March 2024

IPCC claims that Global Warming is caused more or less exclusively by
anthropogenic emissions of CO2. Therefore, only a total stop of these
emissions could avoid a disaster. In IPCC’s reasoning, two concepts are
central: The “constant airborne fraction”, according to which about 50
% of all anthropogenic emissions remain in the atmosphere, whatever the
emissions and whatever the concentration, and the “fixed carbon
budget”, which is the maximum amount humans may emit, when Global
Warming should stay below a given limit, independent of the temporal
distribution of the emissions. In this article, it is shown that three
prerequisites must be fulfilled for these two central concepts to be
viable: All natural sources of CO2 must have remained constant, the
short-term partners of the atmosphere must store the same amount of CO2
as the atmosphere itself, and the atmosphere together with its
short-term partners must be a closed system. And it is shown with high
confidence that, according to the rules of physics, all three are not
fulfilled. If this were confirmed, it would have a serious impact on the
entire climate debate. A careful review seems to be needed urgently.
The Effect of Pseudo-Global Warming on the Weather-Climate System of Africa in a Convection-Permitting Model
Authors: Ocasio Kelly M Nunez , Dougherty Erin
Published: March 2024

The weather-climate system of Africa encompassing the African easterly
jet (AEJ) and the West African Monsoon (WAM) can largely modulate
high-impact weather over Africa and the tropical Atlantic. How the
weather-climate system of Africa will change with a warming climate is
just starting to be addressed due to global climate model limitations in
resolving convection. We employ a novel atmospheric
convection-permitting model regional setup alongside the pseudo-global
warming (PGW) approach to address climate change impacts on the
weather-climate system of Africa. Our findings indicate that the AEJ and
areas of monsoon flow intensify in a future warming climate scenario
together with an increase in monsoonal moisture. Moreover, precipitation
will increase over high topography and shift southward due to a
latitudinal expansion and increase of deep convection closer to the
equator. This has relevant ramifications for the livelihood of
communities that depend on water-fed crops in tropical Africa.

Authors: Alsad Md. Abdula , Mashrafi Md.
Published: March 2024

This study examines the evolutionary trends in predatory adaptation among indigenous dog breeds from Asia. Through a review of literature and historical records, we investigate how selective pressures and human interventions have shaped behaviors and traits in breeds such as the Indian Pariah, Korean Jindo, and Chinese Shar-Pei. By analyzing hunting strategies, prey preferences, and morphological features, we aim to understand the influences of natural selection, domestication, and cultural practices on the predatory behavior of Asian dogs. This research provides insights into the unique evolutionary pathways of Asian predatory dogs and their implications for conservation and human-dog interactions.
