As a result of the conducted studies, it was found that the replacement of an aqueous medium with an organic one (acetone), which has a lower value of surface tension, makes it possible to obtain a product with a significantly more developed specific surface area and specific pore volume. So, replacing water with acetone allows you to increase both Itching and Spores by almost ~ 4 times. It was found that with the initial presence of water in the pores of GOA, the average pore diameter of the dried product is 34 nm. Treatment of the synthesized sample with acetone leads to an increase in the average pore diameter of the dried product to 510 nm.

Using Neural Networks to Model Main Belt Asteroid Albedos as a Function of Their Proper Orbital Elements
Authors: Murray Zachary
Published: May 2023

Asteroid diameters are traditionally difficult to estimate. When a direct measurement of the diameter cannot be made through either occultation or direct radar observations, the most common method is to approximate the diameter from infrared observations. Once the diameter is known, a comparison with visible light observations can be used to find the visible geometric albedo of the body. One of the largest data sets of asteroid albedos comes from the NEOWISE mission, which measured asteroid albedos both in the visible and infrared. We model these albedos as a function of proper orbital elements available from the Asteroid Families Portal using an ensemble of neural networks. We find that both the visible and infrared geometric albedos are significantly correlated with asteroid position in the belt and occur in both asteroid families and in the background belt. We find that the ensemble’s prediction reduces the average error in the albedo by about 37% compared to a model that simply adopts an average albedo with no regard for the dynamical state of the body. We then use this model to predict albedos for the half million main belt asteroids with proper orbital elements available in the Asteroid Families Portal and provide the results in a catalog. Finally, we show that several presently categorized asteroid families exist within much larger groups of asteroids of similar albedos—this may suggest that further improvements in family identification can be made.
Tubulointerstitial Nephritis: Underdiagnosed Kidney Disease in Person Living with HIV
Authors: Makmun Afiatin , Fandiarta Aditya Rangga , Sukesi Lilik , Hartantri Yovita
Published: May 2023

BACKGROUND: Kidney disease in human immunodeficiency virus (HIV) is often overlooked. The types of kidney disease in HIV consist of glomerulopathy and tubulointerstitial nephritis. Hypertension, diabetes mellitus, and the use of tenofovir increase the risk of kidney disease.

AIM: The purpose of this study is to analyze the type of kidney disease in person living with HIV using the urine albumin-protein ratio.

METHODS: This research is an analytic observational study. Data were collected using the consecutive sampling. The urine albumin-protein ratio was carried out to differentiate glomerulopathy from tubulointerstitial nephritis.

RESULTS: Screening with dipstick proteinuria in 1148 person living with HIV, total of 189 subjects (16.5%) with proteinuria were obtained, with a urinary protein-creatinine ratio over 150 mg/g in 101 persons (8.7%). The proportion of tubulointerstitial nephritis (73.3%) was higher than glomerulopathy (26.7%). Kidney disease mostly occurs at glomerular-filtration rate ≥90 ml/minute/1.73 m2, specifically glomerulopathy (66.7%), and tubulointerstitial nephritis (52.7%). The risk stratification of cardiovascular complications and worsening of kidney function was mostly at moderate risk (60%), there were 6.9% of study subjects with a glomerular-filtration rate ≥90 ml/min/1.73 m2 with high-risk stratification. There was no significant difference in the proportion of glomerulopathy and tubulointerstitial nephritis based on comorbidities.

CONCLUSION: Kidney disease in HIV is mostly tubulointerstitial nephritis. Evaluation of kidney function and risk stratification needs to be done to reduce the cardiovascular complications and progressive worsening of kidney function.
Correlation of Patient-Reported Preoperative Narcotic Use and Postoperative Requirements in Total Joint Arthroplasty
Authors: Olsen Aaron A. , Dannenbaum Joseph H. , Horan Timothy , Niu Ruijia , Talmo Carl T.
Published: May 2023

Preoperative narcotic use is associated with diminished outcomes and increased complications in patients undergoing primary total joint arthroplasty (TJA). The goal of this study was to compare self-reported and state database identified preoperative narcotic use and correlate it with perioperative narcotic requirements in patients undergoing primary arthroplasty. A total of 788 patients undergoing unilateral TJA from a single institution were examined using self-reported preoperative narcotic use questionnaires and were verified using the Massachusetts Prescriber Awareness Tool (MassPAT). Demographic data, perioperative morphine milligram equivalents, and postdischarge refills were recorded and analyzed. Of the total population, 16.4% of patients undergoing TJA had verified MassPAT narcotics prescriptions preoperatively. Of these patients, 55% accurately reported use to their surgeon. Patients with verified MassPAT narcotic prescriptions required more morphine milligram equivalents than patients without MassPAT prescriptions, regardless of their preoperative self-report at all time points in the study. Patients who accurately reported use required more narcotics than those who did not. Patients with MassPAT prescriptions required more postdischarge refills than patients without MassPAT prescriptions. These data suggest that state-run narcotics databases may be more useful than self-reports for identifying which patients may require more opioids both immediately postoperatively and after hospital discharge.

Published: May 2023

This study investigated predictive factors for return to play among National Football League athletes after operative treatment of ankle fractures and the impacts of these injuries on career longevity and player performance. Athletes who underwent surgery to repair ankle fractures from the 2013 to 2017 seasons were identified from injury reserve lists and press releases. Demographics and season metrics were collected before and after the injury. Statistical analysis assessed for differences in recorded variables between injured and uninjured players. Thirty-one players met study inclusion criteria. Twenty-two (71%) athletes successfully returned to play. Players who did not return showed no significant differences (
P
>.05) in position, age, body mass index, number of games or seasons played preinjury, or snaps per game the season prior to injury and had a significantly lower (42.6%,
P
=.013) preinjury season approximate value (SAV) compared with returning players. Returning athletes showed no significant differences (
P
>.05) in SAV or snaps per game compared with their preinjury season or with uninjured controls. A high preinjury SAV is associated with successful return to play. No difference in game time or performance metrics was detectable between returning players and uninjured controls, or between preinjury and postinjury seasons. [

Authors: Nonthamand Narin
Published: May 2023

The objectives of this study are (1) to explore pre-service teachers’ needs in using educational technology tools for online learning, (2) to develop an online lesson about the use of educational technology tools for pre-service teachers, and (3) to compare the learning achievements before and after taking the lesson. The methodology was divided into three phases. The first phase was a needs assessment concerning the use of educational technology tools in online learning. The samples were 272 undergraduate pre-service teachers at the University of Phayao. The research instrument was a needs analysis questionnaire on the use of educational technology tools in online learning. The collected data was analyzed using Modified Priority Needs Index (PNImodified). In the second phase, an online lesson about the use of educational tools was developed. The research samples were three experts in three different fields, including instructional design, educational technology, and assessment and evaluation. The research instrument used in this phase was a suitability assessment form for the designed online lesson. Document analysis and descriptive statistics were used to analyze the data. In the third phase, the learning achievements before and after completing the lesson were compared. The samples were 112 pre-service teachers at the University of Phayao. The research instrument was a learning achievement test. The data analysis included means, standard deviations, and a t-test.

The results were as follows: 

Regarding the needs analysis concerning the use of educational technology tools in online learning, the pre-service teachers considered that tools for completing learning tasks were the most crucial element. The data collected from open-ended questions revealed that the most critical problems experienced in online learning were learning tools and poor Internet speed.

The results from the suitability test showed that the developed online lesson was overall suitable (M = 2.98, SD = .174).The pre-service teachers’ average post-test score on the achievement test on the use of educational technology tools was higher than the average pre-test score with a statistically significant difference at the .05 level.

Published: May 2023

When it comes to improving people's health, various forms of smart city applications are put to use in the area of smart healthcare. Health care providers are increasingly using the internet of medical things (IoMT) as an environment of linked healthcare systems, computational capabilities, and health monitors to improve the quality of service (QoS). Smart healthcare devices transmit data to IoMT and it requires an efficient solution. IoMT's and 5G networks' importance necessitates the development and testing of a novel multi-hop reinforced clustering-based routing protocol (MRCRP) to improve health data transmission's QoS. Cluster head selection is carried out using an energy-efficient approach to enhance resource usage. Min-max normalization is used to transform original data into meaningful data for more analysis. Using principal component analysis (PCA), relevant features can be extracted. The proposed routing technique is then employed to effectively transmit the data. The suggested approach's performance measures, such as delay, throughput, energy consumption, and packet drop ratio are studied, as is a comparative analysis with standard routing protocols..

Graph theory is the mathematical study of graphs, which are structures that are used to depict relations between items by making use of a pairwise relationship between them. Graphs can be thought of as a visual representation of a mathematical equation. The principles of graph theory will be covered in this chapter.
Graph Neural Network and Its Applications
Authors: Biswas Sougatamoy
Published: May 2023

Graph neural network (GNN) is an emerging field in deep learning. Graphs have more expressive power than any other data structure. Graph neural network is one of the application areas of deep learning, and it has applications in different domains where traditional convolutional neural networks can't give the desired result. Graphs are basically connections of nodes through the edges. In the area of recommendation systems, image processing and fraud detection are some of the few application areas of graph neural networks. As graphs are moveable and mobile in nature, they are more flexible to apply in these domains. GNN deals with these types of problems more effectively than a convolution neural network. To apply GNN to a specific problem domain, data needs to be converted into a graphical format, and then neural network operations can be executed. The main feature of GNN is to inherit information from its neighborhood. This is called graph embedding. This chapter describes basic GNN architecture, GNN advantage over CNN, and its application in different domains.

Published: May 2023

Social networks are complex systems that require specialized techniques to analyze and understand their structure and dynamics. One important task in social network analysis is link prediction, which involves predicting the likelihood of a new link forming between two nodes in the network. Graph convolutional neural networks (GCNNs) have recently emerged as a powerful approach for link prediction, leveraging the graph structure and node features to learn effective representations and predict links between nodes. This chapter provides an overview of recent advances in GCNNs for link prediction in social networks, including various GCNN architectures, feature engineering techniques, and evaluation metrics. It discusses the challenges and opportunities in applying GCNNs to social network analysis, such as dealing with sparsity and heterogeneity in the data and leveraging multi-modal and temporal information. Moreover, this also provides reviews of several applications of GCNNs for link prediction in social networks.

Companies face a variety of difficulties as they try to compete in an increasingly digital world with constrained a lack of resources and conflicting priorities. They need to develop the skills they require in order for their operations, persons, culture, and structure fit together well. With their corporate objectives in a culture, finding the proper employees is one of the most important issues, and it seems like many businesses are having trouble doing so. Another is creating future plans that take into account their requirements. The conventional talent management strategies may not work for the challenging environment that digital transformation has posed to the conventional way of work. The digitalisation has posed a serious challenge to the traditional organisation structures and strategies. The more common approaches to manage talent include collective approaches to full time careers, therein grouping the individuals into categories like graduates, leaders, potential partners etc. Overall it is more of a collectivist approach.

Honeydew associated with four common crop aphid species increases longevity of the parasitoid wasp, Bracon cephi (Hymenoptera: Braconidae)
Authors: Rand Tatyana A. , Senior Laura B.
Published: May 2023

The absence of sugar resources can be an important factor in limiting the success of parasitoids as biological control agents. Restoring vegetation complexity within agricultural landscapes has thus become a major focus of conservation biological control efforts, with a traditional emphasis on nectar resources. Aphid honeydew is also an important source of sugars that is infrequently considered. We carried out a laboratory experiment to examine the potential effects of honeydew from six different aphid species by crop species combinations on the longevity of Bracon cephi Gahan (Hymenoptera: Braconidae), the most important biological control of the wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), a major pest of wheat in the northern Great Plains of North America. The benefits of honeydew for parasitoid longevity varied significantly among different aphid and crop species, illustrating the complexity of these interactions. However, honeydew produced by four aphid species commonly found in wheat, pea, and canola crops significantly increased the longevity (by two- to threefold) of the parasitoid. The study suggests that honeydew provisioning could be an important mechanism underlying the benefits of crop diversification to support biological control that merits further research.
Granuloma faciale in a patient with remitting seronegative symmetric synovitis with pitting edema: a case report
Authors: Saud Al Arfaj Abdurhman , Khalil Najma , Alzahrani Malak , Husain Sufia
Published: May 2023

Granuloma faciale (GF) is a rare benign chronic inflammatory dermatologic disease which is characterized by facial lesions. The diagnosis is mainly based on clinical and histopathology findings. It may be resistant to treatments and prone to relapse. Different treatment modalities include corticosteroid therapy, tacrolimus, cryotherapy and surgical methods. We report a case of GF in a patient with Remitting seronegative symmetric synovitis with pitting edema (RS3PE). A male patient with RS3PE presented with reddish brown soft nodules on and over lateral aspects of his nose and adjacent areas on his face which were diagnosed histologically as GF. He was treated with prednisolone, methotrexate and clobetasol propionate cream successfully without recurrence. To the best of our knowledge this is the first case report of GF occurring in a patient with RS3PE.
Towards ecological flows: status of the benthic macroinvertebrate community during summer low-flow periods in a regulated lowland river

Published: May 2023

Climate change along with the increasing exploitation of water resources exacerbates low-flow periods, causing detrimental effects on riverine communities. The main mitigation measure currently adopted to counteract hydrological alterations induced by off-stream diversion is the release of minimum flows (MFs), even if within the European Union Water Framework Directive an upgrade towards ecological flows is urgently required to achieve good ecological status (GES). In this study, we investigated the temporal evolution of the benthic macroinvertebrate community in an Italian-regulated lowland river (Ticino River) to clarify the ecological effects of summer low flows, and we evaluated the current MFs in the perspective of meeting GES standard. Biomonitoring was carried out for four consecutive years (2019-2022), in a river site immediately below a large off-stream diversion. The four study years were characterized by different streamflow patterns, thus allowing us to compare the temporal trajectories of the community under different flow conditions. Moreover, the interruption of the low-flow periods due to overflow spilled by the upstream dam gave us the opportunity to assess the effects of experimental flow peaks. Contrary to the expectation, the macroinvertebrate assemblage kept almost unvaried across the years, showing great resistance and resilience to hydrological changes. Even in extraordinarily dry 2022, the community composition varied only slightly, with a reduction of mayflies and an increase of mollusks. However, a deterioration of the ecological status below GES standard was recorded that summer, indicating the need for an upgrading of the current MFs. This upgrade would include experimental flow peaks in critical periods, which act as intermediate disturbances, enhancing community richness, diversity, and overall quality, as well as compliance with a threshold of an index specifically developed for the hydrological pressure.
Current Status of Korean Alcohol Drinking in Accordance with the Korean Alcohol Guidelines for Moderate Drinking Based on Facial Flushing
Authors: Lee Sami , Kim Jihan , Kim Jong Sung
Published: May 2023

Since each person has a different ability to break down alcohol, it is inappropriate to apply a uniform standard to everyone when evaluating drinking status. In Korea, there has been a guideline for moderate drinking based not only on sex and age but Koreans’ alcohol metabolism capabilities that can be predicted by presence of facial flushing response. So far, there have been no studies that have investigated drinking habits of Koreans in accordance with the guideline. This study tried to identify the current drinking status of Koreans according to the guideline. As a result, it was confirmed that about 1/3 of the total population was accompanied by facial flushing when drinking alcohol, and it was found that different drinking habits were shown even in the same age and gender groups according to the presence of facial flushing. It is difficult to accurately evaluate drinking habits because facial flushing has not yet been investigated in some large data or various medical examinations. In the future, it is necessary to ensure that the presence of facial flushing can be confirmed at the medical treatment or examination site so that accurate drinking habit evaluation and prevention and resolution of drinking problems can be achieved.
Religion and identity polarisation: A slight note from the frontier region
Authors: Ichsan Azis Muhammad N. , Amir Muhammad , Subair Muh. , Syamsurijal Syamsurijal , Asis Abdul , Syuhudi Muhammad I.
Published: May 2023

This article examined the recent emergence of the national and international issue of religious polarisation and identity, which affects some groups’ populism and fanaticism. Regarding social phenomena, religion and identity are intertwined like the two sides of a coin. This discourse has an impact how to interpret diversity on religious issues that are caused by political influences. Given the polarisation of identity politics and religion, the national and state campaign slogan ‘unity in diversity’ is merely wishful thinking. The polarisation of identity and religion is heavily implicated in the Indonesia–Philippines border case; consequently, in some instances, the ‘seeds’ of these cases are discovered, eventually resulting in group fanaticism. This article employed the historical way of writing while also taking a social science angle that interacts with the research being done. For some communities, religion and identity may take on symbolic meaning, affecting how well they adapt and are accepted. However, the qualities of a community group or region are also shaped by historical events. According to the study’s findings, religion and ethnic identity have played important roles in long-standing historical processes and impacted them. This study is anticipated to ‘suppress’ the problem of political division involving religion and identity because the identification of ‘border’ communities depends not only on entity and identity issues but also on the community’s culture.Contribution: The contribution in this study is that it has an impact on religious issues and cultural identity relations perspectives.
Electronic library resource use by postgraduate students at a university of technology in South Africa
Authors: Mashaba Makhanani C. , Pretorius Agnieta B.
Published: May 2023

Background: A university of technology in South Africa provides different kinds of e-library resources to its users. Not much is known about the use of these e-library resources by postgraduate students. The existing literature focuses mostly on using e-library resources by all university students and do not specifically emphasise postgraduate students. Therefore, there is a need for a study to investigate the use of e-library resources by postgraduate students.Objective: The study aimed to investigate the use patterns and the factors influencing the use of e-library resources by postgraduate students of a university of technology in South Africa.Method: The unified theory of acceptance and use of technology (UTAUT) model was used to conceptualise the study. A quantitative approach was used with a descriptive survey research method. Questionnaires were designed and distributed through email using survey monkey.Results: Facilitating conditions (FCs) directly influence postgraduate students’ intention to use e-library resources and age moderates the influence of facilitating conditions on e-library resource use. Mediated by behavioural intention (BI), e-library resource use is influenced by performance expectancy (PE), by effort expectancy (EE) and by social influence (SI).Conclusion: The UTAUT model was used to determine the use patterns and the factors influencing the use of e-library resources by postgraduate students of a university of technology in South Africa.Contribution: The literature has underemphasised the need to investigate the influence of postgraduate students in South African universities using e-library resources. Therefore, the study results are expected to fill that gap.
Torsion in the space of commuting elements in a Lie group
Authors: Kishimoto Daisuke , Takeda Masahiro
Published: May 2023

Let G be a compact connected Lie group, and let
$\operatorname {Hom}({\mathbb {Z}}^m,G)$
be the space of pairwise commuting m-tuples in G. We study the problem of which primes
$p \operatorname {Hom}({\mathbb {Z}}^m,G)_1$
, the connected component of
$\operatorname {Hom}({\mathbb {Z}}^m,G)$
containing the element
$(1,\ldots ,1)$
, has p-torsion in homology. We will prove that
$\operatorname {Hom}({\mathbb {Z}}^m,G)_1$
for
$m\ge 2$
has p-torsion in homology if and only if p divides the order of the Weyl group of G for
$G=SU(n)$
and some exceptional groups. We will also compute the top homology of
$\operatorname {Hom}({\mathbb {Z}}^m,G)_1$
and show that
$\operatorname {Hom}({\mathbb {Z}}^m,G)_1$
always has 2-torsion in homology whenever G is simply-connected and simple. Our computation is based on a new homotopy decomposition of
$\operatorname {Hom}({\mathbb {Z}}^m,G)_1$
, which is of independent interest and enables us to connect torsion in homology to the combinatorics of the Weyl group.

Hepatitis B virus (HBV) infection is a major public health problem in Sierra Leone, yet reliable estimates of cases are lacking. This study aimed to provide an estimate of the national prevalence of chronic HBV infection in the general population and select groups in Sierra Leone. We used the electronic databases PubMed/MEDLINE, Embase, Scopus, ScienceDirect, Web of Science, Google Scholar, and African Journals Online to systematically review articles reporting hepatitis B infection surface antigen seroprevalence estimates in Sierra Leone during 1997–2022. We estimated pooled HBV seroprevalence rates and assessed potential sources of heterogeneity. Of 546 publications screened, 22 studies with a total sample size of 107,186 people were included in the systematic review and meta-analysis. The pooled prevalence of chronic HBV infection was 13.0% (95% CI, 10.0–16.0) (I2 = 99%; Pheterogeneity < 0.01). During the study period, the HBV prevalence rates were as follows: 17.9% (95% CI, 6.7–39.8) before 2015, 13.3% (95% CI, 10.4–16.9) during 2015–2019, and 10.7% (95% CI, 7.5–14.9) during 2020–2022. The use of the 2020–2022 HBV prevalence estimates corresponded to 870,000 cases of chronic HBV infection (uncertainty interval, 610,000–1,213,000), or approximately one in nine people. The highest HBV seroprevalence estimates were among adolescents aged 10–17 years (17.0%; 95% CI, 8.8–30.5), Ebola survivors (36.8%; 95% CI, 26.2–48.8), people living with HIV (15.9%; 95% CI, 10.6–23.0), and those in the Northern Province (19.0%; 95% CI, 6.4–44.7) and Southern Province (19.7%; 95% CI, 10.9–32.8) regions. These findings may help inform national HBV program implementation in Sierra Leone.
The Effect of Anethum Graveolens on Male Fertility: Systematic Review and Meta-Analysis
Authors: Mohammed Seid , Alem Berihu Birhane , Beyene Tekleberhan
Published: May 2023

The literature survey has reported that Anethum graveolens extract is inescapably linked with fertility. Recent studies showed that the aqueous extract of Anethum graveolens extract has an adverse effect on male fertility by affecting serum testosterone level, sperm concentration as well as sperm motility. However, its evidence has not been established. The present paper tries to determine the level of evidence for the effect of dill (Anethum graveolens) on male fertility. MEDLINE, Cochrane Library, PubMed, Academic Search Complete, SPORT Discus, Science Direct, Scopus, Web of Science, and Google Scholar were searched to retrieve the literature used for this review. Keywords utilized across the database search were dill, Anethum graveolens, mice, male fertility, randomized control trial, and experimental. The search was limited to studies in animals; published in the English language. Meta-analysis was conducted to examine the effect of Anethum graveolens (dill) extract administration on male fertility. The overall methodological quality of evidence was assessed using the Pedro scale. Out of 25 studies, four trials met the inclusion criteria for this review. All the studies were included in the meta-analysis. Of these, four studies were included for the analysis of sperm concentration, three studies for sperm motility, and two studies for serum testosterone hormone levels. The meta-analysis results suggested there were no significant differences between male fertility and other interventions in the effects of inducing male infertility. The number of studies regarding the current topic is scarce. The overall quality of evidence was very low. Therefore, it is difficult to conclude whether the aqueous extract of dill seed has or has no adverse effect on male fertility. Considering our meta-analysis, we recommended that there is a need for further investigation to provide adequate evidence for the effect of dill (Anethum graveolens) on male fertility.
Psychological Characteristics of Professional Soccer Players and their Comparison with Amateur Players
Authors: Sultanov Murad
Published: May 2023

The purpose of this study was to test the association between personality traits and competitive anxiety among professional soccer players and amateur soccer players (n=78), whose ages ranged from 17 to 21 years.  Personality traits were defined using the Eysenck Personality Questionnaire (translated and adapted version). Participants completed the Sport Competition Anxiety Test by Martens to assess their state of anxiety. The study revealed the dominance of sanguine and choleric temperament, corresponding to extraversion in the representatives of both groups. A one-way ANOVA demonstrated a statistically significant difference (p ≤ 0.03) between the competitive anxieties of the two groups. The results of the stepwise linear regression analysis demonstrated a statistically significant relationship (p ≤ 0.0001) between competitive anxiety and both psychoticism and neuroticism among professional soccer players. According to the results, psychoticism and neuroticism predict the formation of competitive anxiety in professional soccer players. In soccer, the level of competition causes personality differences by psychoticism and neuroticism, however, extraversion is the factor of pre-existing differences, which draw any players into a team sport. Coaches should spend more time on competitive games among youth players because it can help to adapt the autonomic nervous system and reduce excessive levels of anxiety.
