Manures improve soil fertility and crop yield; however, the optimum rate and method of application are important. This experiment was conducted to determine the impact of different rates and modes of application of Tithonia diversifolia on the yield and yield component of two maize varieties. The trial was conducted at the Teaching and Research Farm of the, (federal university, Oye Ekiti, Nigeria during the 2020 and 2021 cropping seasons). The experiment was laid out in a factorial arrangement fitted into a randomized complete block design replicated 3 times. The trial comprised of two maize varieties (LNTP-W and SAUWUAZ), two methods of application of Tithonia diversifolia amendments (chopped and and unchopped). Grain yield and yield components were measured. The result showed that significant difference (P < 0.01) was observed among the maize varieties for number of seeds per cob, 100 seed weight and grain yield. Also the status of amendments showed significant (P < 0.01) impact on cob length while the quantity of the amendment also had significant (P < 0.01) impact on the number of rows per cob, number of seeds per cob, 100 seed weight and grain yield in both years. Significant (P < 0.01) interaction was observed between the maize varieties and quantity of amendments used. Also the status of the amendment x quantity had significant (P < 0.01) impact on the number of rows per cob. However, varieties x status x quantity showed significant impact on the number of seeds per row and number of seeds per cob in 2021.

Dusun III Sri Pengantin adalah salah satu dusun yang berada di Kecamatan STL Ulu Terawas Kabupaten Musi Rawas yang berada dipedalaman. Dikatakan pedalaman dikarenakan aksesnya yang terisolir dan hanya dapat ditempuh dengan menggunakan alat air yang dikenal dengan “ketek”. Dusun yang terisolir dan akses yang sulit juga menjadi penyebab tingkat ekonomi masyarakatnya yang masih rendah. Selain itu, akses yang sulit juga menyebabkan fasilitas dan petugas kesehatan tidak tersedia di dusun ini dan jikalapun tersedia hanya datang 1 (satu) bulan sekali, sehingga kebanyakan untuk masalah kesehatan, masyarakat lebih mengandalkan dukun. Selain mengandalkan dukun, sebagai pengganti penggunaan obat kimia, masyarakat lebih memanfaatkan tumbuhan di sekitar yang memiliki potensi sebagai obat. Berdasarkan permasalahan tersebut, maka peneliti tertarik untuk melakukan penelitian tentang tumbuhan obat yang digunakan oleh masyarakat pedalaman untuk mendata jenis, cara pengolahan, dan organ tumbuhan yang digunakan oleh masyarakatnya. Penelitian ini menggunakan metode jelajah dengan teknik pengumpulan data menggunakan lembar observasi, lembar wawancara, dan dokumentasi. Berdasarkan hasil penelitian diketahui bahwa tumbuhan obat yang digunakan oleh masyarakat dusun III Sri Pengantin terdiri dari 63 jenis dan 39 famili dengan bagian tumbuhan yang digunakan sebanyak 11 bagian, yaitu akar, batang, biji, buah, bunga, daun, getah, kulit buah, rimpang, umbi, dan lendir serta cara pengolahan tumbuhan yaitu direbus, ditumbuk, tanpa diramu, diparut, dioles, ditempel, diasap, dijemur, diseduh, dikukus, dan diperas. Disimpulkan bahwa tumbuhan obat dapat dijadikan alternatif pengganti penggunaan bahan kimia.

Published: May 2023

<p>Reliable and fast channel estimation is crucial for next-generation wireless networks supporting a wide range of vehicular and low-latency services. Recently, deep learning (DL) based channel estimation has been explored as an efficient alternative to conventional least-square (LS) and linear minimum mean square error (LMMSE) approaches. Most of these DL approaches have not been realized on system-on-chip (SoC), and preliminary study shows that their complexity exceeds the complexity of the entire physical layer (PHY). The high latency of DL is another concern. This paper considers the design and implementation of deep neural network (DNN) augmented LS-based channel estimation (LSDNN) for { \color{black} preamble-based orthogonal frequency-division multiplexing (OFDM) physical layer (PHY)} on SoC. We demonstrate the gain in performance compared to the conventional LS and LMMSE approaches. Via software-hardware co-design, word-length optimization, and reconfigurable architectures, we demonstrate the superiority of the LSDNN over the LS and LMMSE for a wide range of signal-to-noise ratio (SNR), number of pilots, preamble types, and wireless channels. Further, we evaluate the performance, power, and area (PPA) of the LS and LSDNN application-specific integrated circuit (ASIC) implementations in 45 nm technology. We demonstrate that word-length optimization can substantially improve PPA for the proposed architecture in ASIC implementations. </p>
Generalized Framework for State Feedback-based Islanding Detection for Distributed Generators
Authors: Maulik Sugoto , John Vinod 
Published: May 2023

<p>This paper presents a method for islanding detection of power-electronic interfaced grid-tied distributed energy resources. A dynamic phasor-based modeling approach is used to synthesize a state-space model of the islanded network. This model leads to the formation of a generalized framework wherein the application of state feedback is designed to destabilize the islanded network. The proposed method can detect islands within one fundamental cycle of operation with passive loads of unity, lagging, and leading power factors. The detection scheme has a zero Non-detection Zone (NDZ), and detection times are within the criteria suggested in IEEE Std. 1547-2018. </p>

Authors: Aprilia Dinda , Decroli Eva , Kam Alexander , Putra Robby Satria 
Published: May 2023

Background: Gestational diabetes mellitus (GDM) is defined as a condition of glucose intolerance that is found during pregnancy. In pregnant women, urinary tract infection (UTI) is one of the most common bacterial infections that can be found. The infection can be worsened by diabetes as it was shown that the risk of UTI in pregnant women with diabetes (27.6%) is higher than those without diabetes (3%-10.1%). This study aimed to present a case of gestational diabetes mellitus and urinary tract infection.
Case presentation: A pregnant woman aged 38 years old with a 15-16 weeks gestational age was admitted with gestational diabetes mellitus and urinary tract infection. The patient was treated with an intravenous insulin drip and antibiotic. The patient was discharged after there was a clinical improvement.
Conclusion: There are many risk factors that can contribute to the development of UTI in pregnant women, with one of those being inadequate glycemic control. The treatment of UTI in pregnant women with GDM is generally the same as in those without GDM.

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

Abstract
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.
Development of an Online Learning Lesson in the Educational Technology Equipment Operation Course for Pre-Service Teachers
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.
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

Abstract
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.
Religion and identity polarisation: A slight note from the frontier region

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.
Torsion in the space of commuting elements in a Lie group
Authors: Kishimoto Daisuke , Takeda Masahiro 
Published: May 2023

AbstractLet 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.

ABSTRACT.
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.
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.
