Published: December 2023

Aim: To determine the prevalence of irritable bowel syndrome among medical students at the University of Benghazi using Rome IV criteria, and to compare the results between students based on their gender and academic year, whether basic (from the first to the third year) or clinical (fourth and fifth years).

Material and Methods:  A cross-sectional observational study was carried out among medical students at the University of Benghazi using Rome IV criteria. Data was collected from June 10th, 2022, to August 31st, 2022, and a semi-structured questionnaire was used. The sample included students from the first year to the fifth year of medicine.

Results: This study included data from 381 medical students, whose ages ranged from 19 to 39. The prevalence of irritable bowel syndrome was found to be 16.01%. Our study found no association between IBS symptoms and gender (p = 0.79). Additionally, no association was observed between IBS symptoms and academic year (p = 0.076), coffee consumption (p = 0.4), as well as smoking (p = 0.9).

Conclusion: The prevalence of irritable bowel syndrome was more observed in females in this study; however, we did not find a significant statistical difference between males and females in the prevalence of IBS. Additionally, there was no significant statistical difference in the prevalence of IBS among medical students whether they were in their basic years or clinical years. Furthermore, in our study, IBS was related neither to coffee nor to cigarette smoking.

“…I value my compositions a bit more highly than the theatre directorate does…” The Frequency of Performances of Smetana’s Operas at the Provisional Theatre and Payment He Received for Them
Authors: Mojžíšová Olga
Published: December 2023

The opera deals with the standing of Smetana’s operas in the repertoire of the Provisional Theatre with respect to the frequency of their performances and the revenue they earned. It is based on a detailed, systematic survey of written sources and especially of Smetana’s diaries, correspondence, repertoire statistics, and other relevant sources. On their basis, there is a presentation of detailed information about the circumstances of performances, frequency of performances, and money earned by Smetana’s individual operas. There follows an attempt to demonstrate the standing of Smetana’s operatic works both overall and for individual operas in the context of Czech opera productions and of the Provisional Theatre’s entire operatic repertoire. Taking into account the financial circumstances of Czech theatre operations, there is also an attempt to answer the question of the extent to which Smetana was justified in his complaints about insufficient numbers of performances of his works.
From the Harp of David to the Bohemian Harp: The Harp in Bohemical Literary Sources of the 16th–19th Centuries
Authors: Slavický Tomáš
Published: December 2023

The study focuses on the defining of the term “Bohemian harp”, and it traces the course of the long-term tradition of use of diatonic harps and hook harps in the Bohemian lands (today Czechia). Because of the lack of other sources, one must seek evidence in iconographical and literary sources. From the 16th century, the harp was known primarily in the context of sacred music. The 19th century saw the emergence of the Přísečnice/Pressnitz and Nechanice versions of the portable hook harp, which were long manufactured as an alternative to the pedal harp. The impoverishment of mountainous regions led to the emergence of the profession of touring musicians. In the Czech language literature of the first half of the 19th century, the harp became associated with the Romantic cult of the bard-prophet, then its prestige declined sharply, until it became an instrument of beggars at the end of the 19th century. The early 20th century saw the last heyday of the Nechanice harp ensembles in the Far East. The scandal created in the press over this entrepreneurship turned public opinion against the harp business and the hook harp, and awareness of the instrument vanished after the First World War.
Half-precast “crossbar-slab-column” frame joint
Authors: Komarov V. A. , Laskov S. N.
Published: December 2023

Introduction. Half-precast frames embodied the positive properties of both precast and cast-in-situ structures. These structural systems are difficult to introduce due to their low level of knowledge, lack of experimental data, and an almost complete absence of a regulatory and technical framework for a design. This stimulates a need to improve and develop new joints with high operational reliability and manufacturability.

Aim. To identify the causes of the frame joint destruction.

Materials and methods. The frame joint is provided by the hidden cast-in-situ column cantilever in the grooves of crossbars and half-precast floor slab with the installation of additional longitudinal and transverse reinforcement. Precast and cast-in-situ elements interact mainly by reinforcement starter bars. The destruction of frame joints was considered using the example of a half-precast frame with the main spans of 9 and 12 m in a two-storey building according to the results of a full-scale survey during the construction period.

Results. At the joints of most crossbars with columns, inclined cracks were detected in the support zones along the lateral surfaces with an opening width of 0.1–5 mm. In addition, cracks were observed along the contact area of the support crossbar groove with the column grouting concrete. An opening revealed them spreading into the body of the groove grouting concrete along the column edge. No adhesion between the walls of a crossbar groove with the joint grouting concrete is observed. The crack formation pattern indicates the determined contour of the floor slab punching above the column.

Conclusion. The cause for the destruction of half-precast frame joints involves the insufficient bearing capacity of the section for the action of transverse forces due to the ductility of precast and cast-in-situ elements.

Published: December 2023

Linear nitramines (R-N(R′)NO2; R′ = H or alkyl) are toxic compounds, some with environmental relevance while others are rare natural product nitramines. One of these natural product nitramines is N-nitroglycine (NNG) is produced by some Streptomyces strains and exhibits antibiotic activity towards Gram-negative bacteria. An NNG degrading heme enzyme, called NnlA, has recently been discovered in the genome of Variovorax sp. Strain JS1663 (Vs NnlA). Evidence is presented that NnlA and therefore, NNG degradation activity is widespread. To achieve this objective, we tested characterized and tested the NNG degradation activity of five Vs NnlA homologs originating from bacteria spanning several classes and isolated from geographically distinct locations. E. coli transformants containing all five homologs converted NNG to nitrite. Four of these five homologs were isolated and characterized. Each isolated homolog exhibited similar oligomerization and heme occupancy as Vs NnlA. Reduction of this heme was shown to be required for NnlA activity in each homolog, and each homolog degraded NNG to glyoxylate, NO2– and NH4+ in accordance with observations of Vs NnlA. It was also shown that NnlA cannot degrade the NNG analog 2-nitroaminoethanol. The combined data strongly suggest that NnlA enzymes specifically degrade NNG and are found in diverse bacteria and environments. These results imply that NNG is also produced in diverse environments and NnlA may act as a detoxification enzyme to protect bacteria from exposure to NNG.

Proposals for the formation of a strategic management system in a shipping company are outlined. It is presented in the form of a certain organizational structure, between which internal and external connections are established, carried out thanks to appropriate information support. A scheme for the interaction of elements of the system of strategic management of fleet operations is proposed.Strategic management processes are carried out at the center for the adoption and implementation of strategies in accordance with the developed algorithm. At the same time, a set of tasks is considered to justify individual strategies in the modern conditions of shipping companies operating on inland waterways. The most pressing tasks of the strategic management process of a shipping company are the development, adoption and development of strategies for using the fleet for transportation. At the same time, risk factors caused by the probabilistic nature of changes in the level of the depths of the shipping channel are taken into account. The problem was solved using an economic-mathematical model in a parametric formulation.The specific operational conditions of the fleet in the Yenisei basin are considered. The result of its implementation are proposals for the introduction of a rational strategy for using the fleet in given directions of cargo transportation.

Urban regions face numerous challenges in implementing regional autonomy. The smart city concept has been implemented by cities in various countries to tackle these issues. This article aims to comprehend and assess the political laws selected by the Indonesian government to address the challenges of implementing regional autonomy in urban areas using smart city concepts and indicators. The research method employed was normative research through a statutory regulations approach, in addition to a conceptual approach. The research material was secondary data comprising primary legal materials as well as secondary legal materials amassed via online and offline research at the library. The data was then analyzed in a descriptive manner. The analysis results demonstrate that numerous Indonesian cities have introduced smart city indicators. However, these indicators lack a legal foundation referencing smart city standards. The absence of specific regulations for smart cities in Indonesia has resulted in unstructured and immeasurable implementation. In Indonesia, the closest legal regulations or policies to the concept of a smart city are those outlined in Government Regulation Number 38 of 2017 concerning Innovation. Going forward, it is necessary to establish legal guidelines that contain specific standards for smart cities, from inception to implementation, in order to enhance regional autonomy in urban areas.

Published: December 2023

As property development and information technologies are going rapid in these few decades, information construction becomes necessarily as a management tool. Changes and variations in construction projects are common and inevitable. This paper aims to study potentials of Building Information Modelling (BIM) in managing variations. The research objective is to identify the potentials of BIM in managing variations. Qualitative method was adopted for this research. Semi-structured interviews were conducted with the respondents to collect data. Twelve respondents were chosen based on the following criteria: (a) involved in BIM projects and (b) experts with BIM knowledge. The respondents involved in the interviews are BIM software providers, BIM software resellers, BIM consultants, main contractors and government personnel in Malaysia. From the interview findings, the potentials of BIM in managing variations are to reduce the variations due to design-related changes, material-related changes, information discrepancies and construction method. Resolving design-related changes includes better visualisation, design coordination, clash detection, better decision making and minimised uncertainties. Managing material-related changes involves automated quantity taking-off, detailed plan for visualisation and material purchase plan. Reducing information discrepancies involves data digitalisation, communication and collaboration, real-time tracking changes as well as improved on request for information (RFI) process. Minimising variations due to construction method includes simulation, better site management and prefabrication with BIM. This research proves that it is necessary to promote BIM management approach in managing variations.

Phytoarchitecture Design for Public Roads to Combat Air Pollution Resulting from Transport Operations
Authors: Harida Samudro  , Ganjar Samudro  , Sarwoko Mangkoedihardjo
Published: December 2023

Public roads and all their activities interact with the environment outside. The interaction was related to transportation pollutants and their recipient bodies, plants, air, and soil. The interaction of these environmental components can produce air pollution and requires prevention solutions. Plants are considered capable of weakening pollution; thus, this study aims to design a novel phytoarchitecture for public roads where roadside plants reduce air pollutants. The method for achieving this goal was based on selected empirical research, which was searched, collected, and selected using the Mendeley reference manager platform with the search phrase: roadside plants, heavy metals, and gaseous pollutants. The selection of hundreds of literatures was carried out in three screening stages. The organisation of this literature review used the ecological approach of transportation pollutants and roadside plants. With the intended methodology, the results of this study indicate that gaseous pollutants and heavy metals arise from public road transportation activities. Traces of pollutants can be measured on the surrounding land and especially on plants. There are five functional characteristics of plants, including phytotreatment, which reduces air pollution; phytoaccumulation to store pollutants; phytoindicators to indicate the presence of excessive concentrations; phytotoxicity in response to toxic levels; and phytomonitoring, which can provide early warning system. Finally, an ecological design is proposed for new roads and improving, operating, and maintaining existing roadside plants. In conclusion, the plant roles can be applied as criteria in the architectural design of public roads.
Optimizing The Best Practice of Building Maintenance Management System (BMMS): Modern Computerized System at Strata Title Residential Property in Malaysia
Authors: Norsafiah Norazman  , Nuzaihan Aras Agus Salim  , Siti Balqis Mohd Shukri
Published: December 2023

Investment in building maintenance management is an effective strategy to control the quality of building performance and its condition. In most countries, maintenance activities are based on the basic management concept, which includes planning, monitoring, and controlling. Thus, building maintenance management system (BMMS) should be applied to various types of properties to allocate the relevant maintenance procedures to the specific building that requires the implementation of maintenance activities. Ordinarily, residential property is more concerned with the building maintenance management system (BMMS) due to the well-maintained assets and facilities, while also retaining the building aesthetically to provide an opportunity for future property investment. The value of buildings really depends on their quality and current condition, and this also points out that accurate maintenance activities for residential property in Malaysia provide maximum benefit to the building's performance. However, building maintenance management in Malaysia is mostly based on the conventional system (also known as a paper-based report) rather than the modern computerized system, which makes it ideally difficult to determine the root causes. This commonly proposes inaccurate maintenance activities for strata-title residential buildings. The weaknesses of the current procedure may affect the overall building performance, besides, building defects can also become more critical without any remedial actions from the building owners. Thus, this research will aid in identifying the fundamental shortcomings of paper-based conventional systems and investigating how a modern computerized BMMS might cope with these challenges. However, this study will focus on strata title properties in Peninsular Malaysia. The variables were measured and assessed using a mixed-methods approach that included both qualitative and quantitative components. Twelve (12) building experts from public and private entities, including the public works department (PWD), local authority (LA), and Construction Industry Development Board (CIDB), were interviewed using a qualitative technique. The results from semi-structured interviews were analyzed using descriptive and thematic analyses. Then, 125 respondents were given a questionnaire as part of a quantitative approach, and SPSS version 28 was used to examine the results. The findings are expected to highlight the
Con el uso de la Teoría del Actor-Red ¿participamos en la construcción de un nuevo paradigma en los Estudios Organizacionales?
Authors:   Universidad Autónoma Metropolitana, Jimeno Espadas Ricardo
Published: December 2023

Este documento contiene algunas de reflexiones y consideraciones teórico-metodológicas que fueron generadas como parte del proceso de investigación realizado en el marco de los estudios doctorales. Su objetivo es mostrar evidencia de que en los estudios organizacionales actualmente estamos transitando por una etapa que, a la postre, resultará en un cambio de paradigma. Para ello, la metodología utilizada en este trabajo se confecciona en tres fases: la primera es realizar un análisis del texto La Estructura de las Revoluciones Científicas de Thomas S. Kuhn, en donde se presenta el proceso por el cual transitan los cambios científicos [ciencia normal – anomalía – crisis – revolución – ciencia normal]; en la segunda fase, se realizó una confrontación con textos que en los estudios organizacionales se reconocen como diferentes, dadas las perspectivas teórico-metodológicas que platean; finalmente en el tercera fase, mediante el método deductivo, se argumenta que en los estudios organizacionales se ha transitado de manera continua por este mismo proceso; y que consecuentemente, el desarrollo de la ciencia ha sido permanente, aunque exista un percepción en el gremio de que ha sucedido bajo lo que Kuhn denominó como una proporción de invisibilidad. Lo anterior, por sí mismo se presenta como una prueba de que este nuevo paradigma ha estado bajo construcción, y su orientación, ha generado en los estudios organizacionales, contribuciones que hacen evidente el trabajo que muestra la importancia de las relaciones entre los agentes organizacionales. La principal conclusión es que, la aplicación de la teoría del actor-red (TAR) en los estudios organizacionales, representa una innovación teórico-metodológica, cuyas bases se han sembrado desde mediados de los años noventa; cuando los investigadores buscan ocuparse más de las relaciones que se generan entre los actores y todos los demás elementos que rodean a la organización.
A COMPARISON OF DIFFERENT GIS-BASED INTERPOLATION METHODS FOR BATHYMETRIC DATA: CASE STUDY OF BAWEAN ISLAND, EAST JAVA
Authors: Pratomo Danar Guruh , Safira Rizka Amelia Dwi , Stefani Olivia
Published: December 2023

The bottom surface’s portrayal is crucial in many different practices. Therefore, accurate bathymetry data is required. The interpolation method is one element that influences the accuracy of a Single Beam Echosounder’s depth data. IDW, Kriging, and TIN are three standard interpolation techniques. This study compares these three methods with two scenarios utilizing the spatial analysis to establish the most effective technique for producing the digital elevation model of the seafloor beneath Bawean Island. The IDW exhibits the strongest R-squared (0.9998779 in Scenario-1 and 0.9999875 in Scenario-2) and correlation (0.9998796 in Scenario-1 and 0.9999595 in Scenario-2). It indicates that IDW and bathymetric data have the closest relationships. IDW has the lowest error, as measured by the MAE value (0.02 in Scenario-1 and 0.009 in Scenario-2), followed in both cases by Kriging and TIN. Additionally, the RMSE for IDW shows the same outcome (0.045 in Scenario 1 and 0.016 in Scenario 2). In the meantime, comparing the first and second scenarios reveals that the second, which has fewer data, is preferable to the first. Since the MAE and RMSE in the first scenario are greater than those in the second, we may infer that more data leads to more significant errors.
Structure and Color Gradients of Ultradiffuse Galaxies in Distant Massive Galaxy Clusters
Authors: Zhao Pinsong , Liu F. S. , Cui Qifan , Yesuf Hassen M. , Wu Hong
Published: December 2023

We have measured structural parameters and radial color profiles of 108 ultradiffuse galaxies (UDGs), carefully selected from six distant massive galaxy clusters in the Hubble Frontier Fields (HFF) in a redshift range from 0.308 to 0.545. Our best-fitting GALFIT models show that the HFF UDGs have a median Sérsic index of 1.09, which is close to 0.86 for local UDGs in the Coma cluster. The median axis-ratio value is 0.68 for HFF UDGs and 0.74 for Coma UDGs, respectively. The structural similarity between HFF and Coma UDGs suggests that they are the same kind of galaxies seen at different times, and that the structures of UDGs do not change at least for several billion years. By checking the distribution of HFF UDGs in the rest-frame UVJ and UVI diagrams, we find a large fraction of them are star forming. Furthermore, a majority of HFF UDGs show small U − V color gradients within the 1 ∗ R
e,SMA region, and the fluctuation of the median radial color profile of HFF UDGs is smaller than 0.1 mag, which is compatible to Coma UDGs. Our results indicate that cluster UDGs may fade or quench in a self-similar way, irrespective of the radial distance, in less than ∼4 Gyr.

We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining Type Ia supernova (SN Ia) in NGC 1784 (D ≈ 31 Mpc), from <1 to 180 days after explosion. The high-cadence observations of SN 2022xkq, a photometrically transitional and spectroscopically 91bg-like SN Ia, cover the first days and weeks following explosion, which are critical to distinguishing between explosion scenarios. The early light curve of SN 2022xkq has a red early color and exhibits a flux excess that is more prominent in redder bands; this is the first time such a feature has been seen in a transitional/91bg-like SN Ia. We also present 92 optical and 19 near-infrared (NIR) spectra, beginning 0.4 days after explosion in the optical and 2.6 days after explosion in the NIR. SN 2022xkq exhibits a long-lived C i 1.0693 μm feature that persists until 5 days post-maximum. We also detect C ii
λ6580 in the pre-maximum optical spectra. These lines are evidence for unburnt carbon that is difficult to reconcile with the double detonation of a sub-Chandrasekhar mass white dwarf. No existing explosion model can fully explain the photometric and spectroscopic data set of SN 2022xkq, but the considerable breadth of the observations is ideal for furthering our understanding of the processes that produce faint SNe Ia.

In this paper we report the detection of five strong gamma-ray bursts (GRBs) by the High-Energy Particle Detector (HEPD-01) mounted on board the China Seismo-Electromagnetic Satellite, operational since 2018 on a Sun-synchronous polar orbit at a ∼507 km altitude and 97° inclination. HEPD-01 was designed to detect high-energy electrons in the energy range 3–100 MeV, protons in the range 30–300 MeV, and light nuclei in the range 30–300 MeV n−1. Nonetheless, Monte Carlo simulations have shown HEPD-01 is sensitive to gamma-ray photons in the energy range 300 keV–50 MeV, even if with a moderate effective area above ∼5 MeV. A dedicated time correlation analysis between GRBs reported in literature and signals from a set of HEPD-01 trigger configuration masks has confirmed the anticipated detector sensitivity to high-energy photons. A comparison between the simultaneous time profiles of HEPD-01 electron fluxes and photons from GRB190114C, GRB190305A, GRB190928A, GRB200826B, and GRB211211A has shown a remarkable similarity, in spite of the different energy ranges. The high-energy response, with peak sensitivity at about 2 MeV, and moderate effective area of the detector in the actual flight configuration explain why these five GRBs, characterized by a fluence above ∼3 × 10−5 erg cm−2 in the energy interval 300 keV–50 MeV, have been detected.

The pulsar system PSR J1023+0038 is a very interesting binary with radio millisecond pulsar and low-mass X-ray binary transitions, which depend on the stellar accretion process. We have used Kepler light curves with 1 minute cadence and TESS light curves with 2 minute cadence to study the flare properties of PSR J1023+0038. We detected 516 flare events in the K2 data and 84 flare events in the TESS survey data. We determined the flare rise and delay times, the flare durations and amplitudes, and flare energies. We obtained a value of the power-law index of 0.359 ± 0.023 between the flare energies and decay times, which is similar to the theoretically predicted value of 1/3. This in turn indicates that PSR J1023+0038 might be exhibiting physical mechanisms described by magnetic reconnection theory. Using the maximum likelihood estimation method, we also calculated the power-law index of the cumulative flare frequency distribution, finding 1.87 ± 0.27 for the Kepler data and 1.74 ± 0.29 for the TESS data. Meanwhile, we reduced six FAST observations of PSR J1023+0038 from 2019–2021 using a standard pulsar search procedure. We report that we detected a prompt signal with a period compatible with that found in previous observations of PSR J1023+0038. However, there are several reasons (statistical, excess DM, pulse shape, etc.) as to why the association is not likely.

We investigate the utility of deep learning for modeling the clustering of particles that are aerodynamically coupled to turbulent fluids. Using a Lagrangian particle module within the Athena++ hydrodynamics code, we simulate the dynamics of particles in the Epstein drag regime within a periodic domain of isotropic forced hydrodynamic turbulence. This setup is an idealized model relevant to the collisional growth of micron- to millimeter-sized dust particles in early-stage planet formation. The simulation data are used to train a U-Net deep-learning model to predict gridded three-dimensional representations of the particle density and velocity fields, given as input the corresponding fluid fields. The trained model qualitatively captures the filamentary structure of clustered particles in a highly nonlinear regime. We assess model fidelity by calculating metrics of the density field (the radial distribution function) and of the velocity field (the relative velocity and the relative radial velocity between particles). Although trained only on the spatial fields, the model predicts these statistical quantities with errors that are typically <10%. Our results suggest that, given appropriately expanded training data, deep learning could complement direct numerical simulations in predicting particle clustering within turbulent flows.
Sharp Decay of the Internal Plateau in Gamma-Ray Bursts: The Effect of a Cocoon's Thermal Photons on the Jet Emission

Sub-TeV or TeV γ-rays have been convincingly detected in the afterglows of some gamma-ray bursts (GRBs). The relativistic jet associated with GRBs may be surrounded by a cocoon and thus the thermal photons of the cocoon pervading the emission region of the jet can be upscattered to the very-high-energy regime (e.g., sub-TeV/TeV) by the electrons in the jet. In this scenario, the electrons in the jet cool down and thus the jet emission in the low-energy regime, e.g., the X-ray or optical, may be suppressed. In this paper, we study the effect of the cocoon's thermal photons on the jet emission in the low-energy regime. We find that the jet emission in the low-energy regime is significantly suppressed when the emission region of the jet is just encircled by a hot cocoon. Correspondingly, there is a sharp decay in the light curves of the jet emission in the low-energy regime, which can be understood to signify strong TeV emission in GRBs. Since the radius of the cocoon expands with the observer time t
obs, the suppression of the jet emission in the low-energy regime may be relieved and thus the light curves of the jet emission would return to those of emission without a cocoon-external inverse-Compton cooling effect. For a long-lasting jet with power

We present an analysis of the JDISCS JWST/MIRI-MRS spectrum of Sz 114, an accreting M5 star surrounded by a large dust disk with a shallow gap at ∼39 au. The spectrum is molecule-rich; we report the detection of water, CO, CO2, HCN, C2H2, and H2. The only identified atomic/ionic transition is from [Ne ii] at 12.81 μm. A distinct feature of this spectrum is the forest of water lines with the 17.22 μm emission surpassing that of most mid-to-late M star disks by an order of magnitude in flux and aligning instead with disks of earlier-type stars. Moreover, the flux ratios of C2H2/H2O and HCN/H2O in Sz 114 also resemble those of earlier-type disks, with a slightly elevated CO2/H2O ratio. While accretional heating can boost all infrared lines, the unusual properties of Sz 114 could be explained by the young age of the source, its formation under unusual initial conditions (a large massive disk), and the presence of dust substructures. The latter delays the inward drift of icy pebbles and helps preserve a lower C/O ratio over an extended period. In contrast, mid-to-late M-star disks—which are typically faint, small in size, and likely lack significant substructures—may have more quickly depleted the outer icy reservoir and already evolved out of a water-rich inner disk phase. Our findings underscore the unexpected diversity within mid-infrared spectra of mid-to-late M-star disks, highlighting the need to expand the observational sample for a comprehensive understanding of their variations and thoroughly test pebble drift and planet formation models.
