Cardiovascular diseases (CVDs) are complex, encompassing many types of
heart pathophysiologies and associated etiologies. It has been shown
that fractionated radiation exposure at high doses (3-17 Gy) to the
heart increases the incidence of CVD, as evident from radiotherapy
studies. However, the effects of low doses of radiation on the
cardiovascular system or the effects from space travel, where radiation
and microgravity are important contributors to damage, are not clearly
understood. Herein, the adverse outcome pathway (AOP) framework was
applied to develop an AOP to vascular remodeling from the deposition of
energy. Following the creation of a preliminary pathway with the
guidance of field experts and authoritative reviews, a scoping review
was conducted which informed final key event (KE) selection and
facilitated evaluation Bradford Hill criteria of the key event
relationships (KERs). The AOP begins with a molecular initiating event
of deposition of energy; ionization events increase oxidative stress,
which concurrently causes the release of pro-inflammatory mediators and
alters signaling pathways. These KEs alter nitric oxide levels leading
to endothelial dysfunction and subsequent vascular remodeling (the
adverse outcome). The work identifies evidence needed to strengthen
understanding of the causal associations for the KERs, emphasizing where
there are knowledge gaps and uncertainties in both qualitative and
quantitative understanding. The AOP is anticipated to direct future
research to better understand the effects of space on the human body and
potentially develop countermeasures to better protect future space
travelers.
Prior History of Atrial Fibrillation and Arrhythmic Outcomes - Data from the WEARIT-II Prospective Registry
Authors: Goldenberg Ido , Younis Arwa , McNitt Scott , Klein Helmut , Goldenberg Ilan , Kutyifa Valentina
Published: May 2023

Introduction: Wearable Cardioverter Defibrillator (WCD) is
utilized in patients with assumed but not yet confirmed risk for sudden
cardiac death (SCD). Many of these patients also present with atrial
fibrillation (AF). However, the rate of WCD-detected ventricular or
atrial arrhythmia events in this specific high-risk cohort is not well
understood. Methods: In WEARIT-II, the cumulative probability
of any sustained or non-sustained VT/VF (WCD-treated and non-treated),
and atrial/supraventricular arrhythmias during WCD use was assessed
using the Kaplan-Meier method by prior AF, with comparisons by the
log-rank test. The incidence of ventricular and atrial arrhythmia events
were expressed as events per 100 patient-years, and were analyzed by
prior AF using negative binomial regression. Results: WEARIT-II
enrolled 2000 patients, 557 (28%) of whom had AF prior to enrollment.
Cumulative probability of any sustained or non-sustained WCD-detected
VT/VF during WCD use was significantly higher among patients with a
history of AF than without AF (6% vs. 3%, p=0.001). Similarly, the
recurrent rate of any sustained or non-sustained VT/VF was significantly
higher in patients with prior AF vs. no prior AF (131.5 events per 100
patient-years vs. 22.7 events per 100 patient-years, p=0.001). Patients
with prior AF also had a significantly higher burden of any WCD-detected
atrial arrhythmias/SVT/inappropriate therapy (183.2 events per 100
patient-years vs. 74.8 events per 100 patient-years, p<0.001).
Conclusion: Our results demonstrate that patients with a
history of AF wearing the WCD for risk assessment have a higher
incidence of ventricular arrhythmias that may facilitate the decision
making for ICD implantation.
Estimation of Participation Factors on Power System Oscillation from Measurements
Authors: Xia Tianwei , Yu Zhe , Sun Kai , Shi Di
Published: May 2023

In a power system, the conventional method for computing participation
factors of generators associated with an oscillatory mode involves using
linearized system models and element-by-element products of
corresponding right and left eigenvectors. Unlike traditional modal
analysis methods, this paper proposes a new approach for estimating
participation factors from measurements on generator responses under a
range of disturbances. This method computes extended participation
factors that coincide with accurate model-based participation factors,
provided that the measured responses satisfy an ideally symmetric
condition. This paper further relaxes the symmetric condition by
identifying a coordinate transformation from the original measurement
space to an optimal new space for the best symmetry. Consequently, the
optimal estimation of participation factors solely from measurements is
achieved, and the factors influencing accuracy are discussed. The
proposed approach is comprehensively demonstrated using a two-area
system and then tested on an NPCC 48-machine power system.
Local salt purification in Aceh Timur regency using alkaline (KOH and NaOH) activated bentonite
Authors: Wahyuningsih Puji , Muslimah Muslimah , Yusnawati Yusnawati
Published: May 2023

Various purification methods have been developed to improve local salt quality, with the NaCl content above 94%. Bentonite is one of the materials used as binder impurities in purification. The purpose of the study was to synthesize a modified bentonite using an alkaline solution, which includes sodium hydroxide (NaOH) and potassium hydroxide (KOH) with various concentrations (1 M, 1.5 M, 2 M, and 2.5 M) and determined levels of Na+, Ca2+ and Mg2+ metals using AAS. The bentonite and activating agent 1 M (1:10) were stirred for three hours. Then, the bentonite was dried for two hours in an oven at 110?C. The activated bentonite was dried for four hours at 170?C. The activated bentonite was characterized using XRD, FTIR, and SEM. The basal spacing d001 on the diffractogram bentonite was significantly unaffected by alkaline activation. FTIR analysis represents the stretching vibration of -OH shifts towards a lower wavenumber. Alkaline activation reduced impurities from bentonite and increased the pore surface''s porosity. NaCl levels in people's salt increased after being activated using alkaline. The increase in Na+ levels was followed by a decrease in Ca2+ and Mg2+ contents. KOH-activated bentonite had a higher NaCl level than NaOH-activated bentonite.

Published: May 2023

In this article, we concentrate on the Sz?sz-Jakimovski-Leviatan operators
imposed by Appell polynomials using q-calculus. We analyze the classical
Sz?sz-Jakimovski-Leviatan-Kantorovich and derive the approximation results
connected to the non-negative parameters ? ? [ 1 2 ,?) in q-analogue. In
order to combining with the earlier investigation by utilizing the
Korovkin?s theorem we study the local as well as global approximation
theorems in terms of uniform modulus of continuity of order one and two. We
calculate the rate of convergence by using of Lipschitz-maximal functions.
Moreover, the Voronovskaja-type approximation theorem is also calculated
here.
On interpolative fuzzy contractions with applications
Authors: Muhammad Rafique , Shagari Mohammed , Azam Akbar
Published: May 2023

In this paper, following a new interpolation approach in fixed point theory,
we introduce the concepts of interpolative Hardy-Rogers-type fuzzy
contraction and interpolative Reich-Rus-Ciric type fuzzy contraction in
the framework of metric spaces, and we analyze the existence of fuzzy fixed
points for such contractions equipped with some suitable hypotheses. A few
consequences in single-valued mappings which include the conclusion of the
main result of Karapinar et al. [On interpolative Hardy-Rogers type
contractions. Symmetry, 2019, 11(1), 8] are obtained. On the basis that
fixed point of a single-valued mapping satisfying interpolative type
contractive inequality is not necessarily unique, and thereby making the
notions more appropriate for fixed point theorems of multifunctions, new
multivalued analogues of the fuzzy fixed point theorems presented herein are
deduced as corollaries. In addition, nontrivial examples which dwell upon
the generality of our results are provided. Finally, one of our results is
applied to investigate solvability conditions of a Fredholm integral
inclusion.

Introduction/Objective. Diabetic macular oedema is the accumulation of fluid in the macular tissue leading to its thickening. The aim of the study was to evaluate the efficacy of concentrated triamcinolone acetonide 10 mg / 0.1 ml injection into the suprachoroidal space in patients with diabetic macular oedema and decreased visual acuity. Methods. In 12 eyes with diabetic macular oedema, without any prior treatment, using a small-diameter 26G needle, an injection of 10 mg / 0.1 ml triamcinolone acetonide was applied into the suprachoroidal space in the superotemporal quadrant of the eye 4 mm from the limbus. Prior to the injection, as well as one, three, six, nine, and 12 months after the injection, visual acuity and intraocular pressure were measured, and central subfield thickness was recorded using optical coherence tomography. Results. After one, three, six, and nine post-injection months there was a statistically significant reduction in central subfield thickness (315.92 ?m, 257.66 ?m, 281.08 ?m and 295.51 ?m, respectively) compared to the baseline of 447.67 ?m. At the end of the 12th month an increase in central subfield thickness was observed again (392.16 ?m). Visual acuity improved significantly from the baseline (0.32) during the first three months (0.61) and remained stable until the end of the nineth month (0.51), but at the end of 12 months it decreased again (0.39). No significant intraocular pressure elevation and cataract development were observed in either eye during the entire follow-up period. Conclusion. A single dose of 10 mg / 0.1 ml triamcinolone acetonide injected in suprachoroidal space can significantly stabilize diabetic macular oedema and maintain satisfactory visual acuity for up to nine months.

Antibiotic Resistance and Detection of Blatem and MecA Genes in Bacteria Isolated from Street Vended Pounded Yam in Yenagoa, Nigeria
Authors: VE Ajumobi
Published: May 2023

Antibiotic resistant pathogens spread through food are a public health concern. The aim of this study was to determine the profile of antibiotic resistance and to investigate the presence of genes that produce antibiotic resistance in bacterial isolates from pounded yam collected from five sites in Yenagoa, Nigeria (Swali, Amarata, Kpansia, Tombia, and Akenfa). The Kirby-Bauer disk diffusion method was used to examine antibiotic susceptibility to nine antibiotics (Augmentin, Ofloxacin, Chloramphenicol, Ampicillin, Erythromycin, Gentamycin, Nitrofuratoin, Streptomycin and Tetracyclin), and the PCR method was utilized to find the blaTEM and mecA genes. A total of 150 pounded yam samples were collected and analyzed. Shigella spp, Bacillus spp, Staphylococcus spp, Pseudomonas spp, Salmonella spp, Klebsiella spp, Proteus spp, and Escherichia coli are among the bacteria that were recovered from the pounded yam samples. Except for Pseudomonas spp., all tested positive for multidrug resistance (resistance to three or more tested antibiotics), with the majority of these antibiotics being Chloramphenicol, Ampicillin, Erythromycin, Gentamycin, Nitrofuratoin, Streptomycin, and Tetracyclin. The Escherichia coli isolated from the street-vended pounded yam exhibited multidrug resistance against Ampicillin (37.5%), Erythromycin (43.8), Gentamycin (34.4), Streptomycin (21.9) and Tetracyclin (40.6). Bacillus spp also showed multidrug resistance against Chloramphenicol (36.4), Ammpicillin (36.4), Erythromycin (45.5), Gentamycin (36.4), Nitrofuratoin (36.4), Streptomycin (27.3) and Tetracyclin (36.4). Inhibition zones against Augmentin, Ofloxacin, Chloramphenicol, Ampicillin, Erythromycin, Gentamycin, Nitrofuratoin, Streptomycin, and Tetracyclin were clearly visible in Pseudomonas spp (100, 96.4, 64.3, 50.0, 82.1, 75.0, 64.3, 92.9, and 50.0% respectively). The highest resistance by number of bacterial isolates was found in Erythromycin (6 isolates showed resistance), followed by Tetracyclin (5 isolates showed resistance). Ampicillin and Streptomycin resistance was present in four isolates. Three representative isolates were selected for molecular identification of blaTEM and mecA which were amplified at 600bp and 500bp respectively. These genes were responsible for the antibiotic resistance seen in the isolates. According to this study, the pounded yam samples that were evaluated had food-borne disease strains that are multidrug resistant and a danger to the general public's health. The findings cast doubt on the quality of foods sold on the streets of Yenagoa, Nigeria.

Good environment will affect students' learning outcomes. This study aims to analyze how students' interest in learning and critical thinking skills can be influenced by students' pro-environmental behavior, because a. This study uses a survey technique. In this study, a sample of 50 students was used which was divided into two classes. Analysis of the data used is a simple regression test. After the implementation of this research, it is known that students' responses to PEB-based learning have a significant effect on learning interest and students' critical thinking skills in learning environmental materials. This is evidenced by the t-count value which is greater than the t-table, as well as a lower significance value compared to the tolerance limit value used of 0.05. The novelty in this research is in the material being measured or tested and the number of variables used. Where in the previous study only used one of the three variables that I studied, and had not researched pro-environment. The limitations of this study are limited to knowing the effect of student responses to pro-environmental behavior-based learning (PEB) on interest in learning and student learning outcomes in environmental material learning, not yet on skills or psychomotor aspects. Therefore, it is recommended for further researchers to be able to add aspects that have not been studied in this study to make it more perfect.

Pembakaran batubara dengan kadar sulfur lebih dari 0,23%-berat (dry basis) dengan udara pembakaran berlebih 50% pada Pembangkit Listrik Tenaga Uap (PLTU) batubara dapat menghasilkan SO2 diatas baku mutu emisi yang ditetapkan oleh pemerintah. Penyisihan gas SO2 dari gas cerobong PLTU-batubara dapat melalui proses adsorpsi menggunakan adsorben padat dengan fasa aktif seperti CuO, MgO, CaO, CeO2 yang ditempelkan pada penyangga berbasis oksida logam baik tunggal maupun campuran diantaranya adalah g-Al2O3, SiO2, TiO2. Penggunaan campuran g-Al2O3 dan SiO2 sebagai penyangga didasarkan pada beberapa pertimbangan diantaranya adalah luas permukaan dan volume pori-pori yang besar dan stabilitas termal yang baik. Campuran senyawa g-Al2O3-SiO2 dibuat dengan metode sol gel menggunakan senyawa AlCl3.6H2O dan boehmite sebagai sumber g-Al2O3 dan natrium silikat dan Siral-10 sebagai sumber SiO2. Variabel penelitian meliputi komposisi campuran g-Al2O3 dan SiO2 diperoleh dengan memvariasikan konsentrasi SiO2 dalam larutan natrium silikat (4, 6, 8 dan 10 % v/v) dan temperatur kalsinasi (550, 650 dan 750°C). Hasil penelitian memperlihatkan bahwa variasi konsentrasi SiO2 (% v/v) dalam larutan natrium silikat menghasilkan penyangga dengan sifat pori yang cenderung mirip. Kenaikan temperatur kalsinasi mempengaruhi sifat pori penyangga γ-Al2O3-SiO2. Luas permukaan, total volume pori dan radius pori rata-rata penyangga γ-Al2O3-SiO2 terbaik diperoleh pada temperatur kalsinasi 550°C  masing-masing sebesar 293,724 m2/g; 1,0580 cc/g; dan 67,33Å

Tanah adalah pendukung pondasi bangunan, kondisi tanah yang kuat diperlukan untuk menahan dan meratakan beban. Tanah dengan daya dukung rendah tidak menguntungkan secara teknis apabila dibangun suatu konstruksi sehingga perlu dilakukan perbaikan sesuai kriteria konstruksi. Tanah pada proyek Tol Kayu Agung - Palembang - Betung pada umumnya berupa tanah kohesif lunak dengan tebal yang cukup dalam, memiliki daya dukung yang rendah, kurang stabil sehingga berisiko menimbulkan keruntuhan atau deformasi yang besar terhadap struktur / bangunan. Metode pelaksanaan yang simultan menyebabkan metode PVD vacuum tidak bisa berdekatan langsung dengan abutment struktur sehingga diperlukan penanganan khusus terhadap untreated zone atau daerah transisi. Area transisi perlu didesain agar penurunan area jembatan dan area transisi dapat terjadi sekecil mungkin agar kenyamanan berkendara masih bisa terpenuhi. Oleh karena itu metode alternatif untuk menghilangkan potensi penurunan jembatan sangat dibutuhkan. Metode perkuatan dengan pemasangan sistem cerucuk mini pile dan penggunaan matras beton di atasnya dipilih dengan pertimbangan biaya pekerjaan yang relatif lebih murah dengan hasil yang optimal. Berdasarkan perhitungan, hasil dari pemakaian cerucuk matras beton pada area oprit jembatan menghasilkan penurunan tanah sebesar 3 cm (batas ambang distorsi 3,2 cm) pada 10 tahun pembebanan lalu lintas.

Ketersediaan jalan sebagai prasarana transportasi dapat menumbuhkan konektivitas antar lokasi dan daerah yang membentuk suatu jaringan transportasi. Konektivitas antara daerah yang satu dengan daerah lain dapat terbentuk dengan adanya berbagai jaringan transportasi antar daerah yang dapat memungkinkan pemindahan barang dan jasa atau orang dari satu tempat ke tempat lainnya. Kondisi jalan yang baik dan berdaya guna merupakan tujuan dari setiap perencanaan dan pembangunan prasarana transportasi. Kemampuan jalan yang menurun dalam pemenuhan pelayanan pengguna jalan dapat menyebabkan konektivitas jaringan jalan menjadi terganggu. Hal ini dapat membuat dampak yang tidak diinginkan baik dari segi keselamatan maupun dari segi kenyamanan. Sementara itu kebutuhan masyarakat akan value pelayanan dan kenyamanan menjadikan acuan berbagai pihak dalam perwujudan jalan yang berkelanjutan. Kerusakan pada perkerasan  pada ruas jalan kabupaten di wilayah Kecamatan Gunung Labuhan merupakan permasalahan yang kompleks terutama bagi pengguna jalan.

Pembangunan Jalan Tol Ruas Kayu Agung - Palembang - Betung Paket IV seksi 2A memiliki panjang 15,2 km + 3,4 km untuk Interchange (IC) Musi Landas. Kondisi tanah pada area proyek tol Kayu Agung – Palembang– Betung yang merupakan mayoritas adalah tanah lunak menyebabkan sulitnya melakukan pekerjaan tanah. Differential settlement yang terjadi pada ruas tol sebelumnya yaitu di Gerbang tol Kramasan dan dampak dari kendaraan Over Dimension and Over loading (ODOL) inilah yang mendasari penggunaan sistem Cakar Ayam Modifikasi (CAM) pada area gerbang tol IC Musi Landas, untuk memitigasi risiko yang terjadi di ruas sebelumnya. Sistem CAM masih mampu menjaga kerataannya karena adanya pipa-pipa CAM yang ditancapkan ke dalam tanah (tanah timbunan) memiliki kemampuan untuk mendukung gaya vertikal ke bawah, gaya vertikal ke atas (sebagai angkur yang mampu menyatukan pelat dengan permukaan tanah agar pelat tidak terangkat – tidak terjadi gap / celah antara tanah dengan permukaan bawah pelat), mendukung momen yang besar ke semua arah, mendukung gaya horizontal (rotasi pipa) ke semua arah. Kekakuan Sistem CAM ini menjaga terjadinya perbedaan penurunan dalam jangka panjang (Jaminan Desain CAM 10 Tahun) dibandingkan dengan konstruksi lain yang diterapkan di atas timbunan yang sama.

The Caspian Sea has a variety of species and groups of aquatic animals, e.g., plankton and fishes that are exploited, unfortunately in the past decade, this sea has entered and expelled of some non-indigenous species such as ctenophore Mnemiopsis leidyi, Copepods Acartia tonsa, Balanidae Balanus improvisus and Mullets Lisa saliens have caused major changes in the Sea. One of the species got common in the coastal waters is M. leidyi with the highest biomass in summer at the temperature of 25-30 °C, and the highest abundance was observed in autumn while the minimum density was in winter of 8-10 °C. The ctenophore distribution of length frequency indicated that while 83% of the population consists of larval and immature organisms, only less than 17% belonged to the adult group in the costal waters of the Caspian. The largest size of the jelly was 70 mm long in the southern Caspian Sea in September 2002. Based on the jelly food consumption, the Nauplius, copepodites and adults of Acartia tonsa consisted 66% and bivalves was 13% in the Caspian. Therefore, it seems the reduction of the comb jelly compared to its early year's invasion was due to the reduction of edible zooplankton especially A. tonsa in the southern of the Caspian Sea. During 2001-2013, Kilka catches amount was decreased to ~15000 kg from 95000 kg in 1996 with the changes of Clupeidae species composition of Clupeonella engrauliformis to C. cultriventris caspia.

The data collection of was based on secondary sources. More specifically, the data collection was carried out based on the principles of historical archival research. For the analysis of the data dance iconography will be used. However, having visual components, dance shares a representative quality with the visual arts. So, in addition, the pictures of women dance in this study will be analyzed under the terms of visual anthropology. Finally, the interpretation of the data was held with the anthropological thinking about gender identity as it appears in anthropological views of dance and particularly in Hanna. From the data analysis was found that the position of women in dance evolved significantly over time, as did the society of Nea Vyssa, which from patriarchal, today became an equal society. So through dance iconography one can study various parameters that exist in dance and which Seebas (1991) also mentioned, however, through dance iconography one can study social stereotypes, gender discriminations and social structures and therefore issues that have to do with the evolution of society over time.
