Optimisation of the Parameters of a Vibration Damper Installed on a Historic Bridge
Authors: Podwórna Monika , Grosel Jacek 
Published: February 2024

Abstract
The paper presents theoretical analyses of renovating a historical bridge in order to decrease stresses. The installation of additional equipment, including a vibration absorber, is relatively easy to perform if such a need is indicated by the current bridge diagnostics or the monitoring of the structure’s vibrations. Moreover, absorbers could be mounted in such a way as not to alter the appearance of the historic structure. The authors focused on the problem of optimising the cooperation between a dynamic vibration absorber (DVA) and a structure under dynamic load moving with constant velocity. A simple degree of freedom (SDOF) system – as a model of the absorber and a multi-degree of freedom (MDOF) system – as the primary structure, were adopted in the calculations. Every force is regarded as a random variable, as well as interarrivals of moving forces. Two different situations and solutions were presented. The first case is when the stream of moving forces with a constant velocity is modelled as the filtered Poisson process. The second one when one of the forces is located in the point of the beam in which the response of the beam has the maximum value.

Authors: Yurkova Kseniya , Krykowski Tomasz 
Published: February 2024

Abstract
The paper presents a comparative analysis of the application of two nonlocal gradient-formulated models to evaluate the concrete cover degradation time. Calculations were made taking into account the increase in the volume of the steel ring around the perimeter of the reinforcement bar. The results of the calculations were compared with the results of experimental studies published in the literature and with the elastic-plastic model based on the Menetrey-Willam surface, in which the objectivity of the obtained results depends on the fracture energy. In addition, the paper compares solutions using different contact models and cohesion models.

Published: February 2024

Abstract
Governments worldwide have established lockdowns to limit the spread of COVID-19 during the pandemic. The restrictions on travel and reduction of economic activity have led to a temporary improvement in air quality in several countries, especially in urban areas. This study investigates the changes in concentration levels of air pollutants (PM10, PM2.5, SO2, NO2, and bacterial aerosol) in the Upper Silesia Region of Southern Poland, during three periods: pre (March 2018 and 2019), during (March 2020, and 2021) and post-COVID-19 lockdown period (March 2022 and 2023). Our findings indicate that COVID-19 restrictions had a moderate impact on PM10 levels in comparison to pre- and post-COVID-19 periods. PM2.5 during lockdown was significantly lower than in the pre-COVID period and not significantly higher after COVID. PM10 and PM2.5 average concentrations decreased during COVID-19 restrictions by 27.8% and 12.7%, respectively. Compared with the results from the pre-COVID-19 phase, the reductions in NO2 and SO2 during the lockdown were 9.5% and 34.0%. Among other pollutants, bacterial aerosol (BA) concentrations also decreased during the lockdown by 23.0%, compared to the results from the pre-COVID-19 period.

Authors: Zajusz-Zubek Elwira , Korban Zygmunt 
Published: February 2024

Abstract
The article presents the measurement results of the concentration of dust PM10 and PM2.5 as well as SO2, NO, NO2 and NOx based on a mobile laboratory located on the campus of the Silesian University of Technology (Poland, Gliwice, Konarskiego 20B, 50.292934N, 18.682164E), in the so-called “winter period” in 2020 (from 01/01/2020 to 31/03/2020 and from 01/10/2020 to 31/12/2020). The obtained results were used to carry out a synthetic (aggregated) assessment of the threat to the anthropogenic environment, the so-called “objects”, i.e. days on which the measurements were made, interpreted as points in the multidimensional space with coordinates corresponding to the measurement results of the concentration of dust pollutants: PM10 and PM2.5 and gaseous pollutants: SO2, NO, NO2 and NOx. The determined synthetic values additionally allowed for ordering (creating rankings) of the examined “objects” in terms of air quality. For the calculations, the Simple Additive Weighting method (SAW) was used, which belongs to the group of single-criteria synthesis methods.
Some theoretical results on fractional-order continuous information measures
Authors: Benmahmoud Slimane 
Published: February 2024

Abstract
By rewriting the differential entropy in a form of a differ-integral function’s limit, and deforming the ordinary derivative to a fractional-order one, we derive in this paper a novel generalized fractional-order differential entropy along with its related information measures. When the order of fractional differentiation α → 1, the ordinary Shannon’s differential entropy is recovered, which corresponds to the results from first-order ordinary differentiation.
Improving Environmental Performance Through Innovative Academic Citizenship Behaviour: Green Training And Development, Green Recruitment And Selection As Antecedents In Jordanian Government University
Authors: Alqudah MohammadNoor Khaled m , Yusof Yusnita 
Published: February 2024

Abstract
Education institutions are thought to be largely responsible for environmental pollution even though businesses of all shapes and sizes contribute to this issue. This research explores how important factors might help government universities in Jordan develop and implement green innovation. It seeks also to examine whether the academic citizenship behaviour is a mediating variable that explains the connection between green training and development, green recruitment and selection, and organization environmental performance. Accordingly, an email survey was conducted to collect responses from 404 employees in the Jordanian Government universities. The study used contemporary variance-based structural equation modelling (Amos-SEM) for data analysis and hypothesis testing. The obtained results indicated a positive association between green training and development and two variables, namely academic citizenship behaviour, and organization environmental performance. They also indicated a positive association between green recruitment and selection and two variables, namely, academic citizenship behaviour and organization environmental performance. As well as between academic citizenship behaviour and organization environmental performance. Furthermore, they showed mediating effects of academic citizenship behaviour in the relationship between green training and development and organization environmental performance and between green recruitment and selection and organization environmental performance. This paper helps to provide insights to HRM practitioners, shedding light on the importance of Green HRM practices and their role in enhancing organization environmental performance.

Published: February 2024

Abstract

Aim. The aim of the study was to make selected nursing diagnoses for a patient after a microsurgical transplant in the facial area, with the aim of providing the patient with comprehensive care in the perioperative period.

Material and methods. The study describes the case of a child after microsurgical transplantation of a flap taken from the left iliac plate to the right submandibular region. The individual case method was used. Clinical interview, observation, measurement and medical documentation data were analyzed.

Results. Four selected nursing diagnoses were presented along with planned interventions: risk of complications at the site of microsurgical flap transplantation, risk of donor site infection, discomfort caused by intense oozing of secretions from the postoperative wound in the oral cavity and the boy’s depressed mood caused by low self-esteem resulting from the changed postoperative facial appearance and the failure of the first surgical procedure.

Conclusions. Nursing interventions should be adapted to the patient’s dynamically changing recovery process. They should be based on systematic inspection of the recipient and donor sites for the occurrence of complications. Education of the patient and the caregiver is an important element of the therapeutic process. It was not possible to significantly improve the child’s mood.
Novel Hypergolic Green Fuels with Hydrogen Peroxide for Propulsion Systems

Published: February 2024

By combining the advantages of chemicals from two different classes, a series of catalytically promoted green hypergolic fuels named polyamine/alkanolamine-based hypergolics (PAHyp) with highly concentrated hydrogen peroxide (96%) as an oxidizer was developed. In this paper, a novel recipe based on [Formula: see text]-tetramethylethylenediamine (TMEDA) and [Formula: see text]-methyldiethanolamine (MDEA), named PAHyp 1, is characterized. Samples with different volume proportions of TMEDA and MDEA catalyzed with 0.5–4 wt% of copper salts were prepared. It was demonstrated that, by adding low catalyst loadings of 1–2 wt%, ultrafast ignition (as low as 8 ms) can be measured. Fast ignition is important to avoid a hard start in the startup phase, and reduced catalyst loading is important to avoid loss of performance in terms of specific impulse. To evaluate the system’s performance, an orbital transfer maneuver of a geostationary satellite that burns monomethylhydrazine with nitrogen tetroxide was considered. It was demonstrated that when using green formulations based on TMEDA/MDEA, smaller propellant tanks are required (because of the higher density of the green propellants), though more propellant mass is required due to a slightly low specific impulse. Besides good performance and reliable ignition, good storability is crucial for long-term space applications. Remarkably, although TMEDA is sensitive to air, visual inspection, ignition tests, and Fourier-transformed infrared spectroscopy analysis revealed that formulations with volume proportions of at least 60% of MDEA stored in vials filled with air survived with no signs of degradation after 14 months. Finally, to meet the requirement of long-term missions of several years in space, a hypergolic tripropellant feed system was proposed.

A study of carbon monoxide (CO) dissociation was performed in a shock tube at conditions relevant to the high-speed entry of Venus and Mars atmospheres. The CO number density (or mole fraction) and the temperature are probed behind reflected shock waves at 1 MHz using scanned-wavelength laser absorption spectroscopy near [Formula: see text] ([Formula: see text]). The wide range of vibrational states ([Formula: see text], and 10) probed by this technique enables precise number density and temperature measurements up to and above 9000 K using a Boltzmann population fit of the resolved spectral lines. Mixtures of CO diluted in Ar at 3–60% are shock-heated in a wide range of conditions ([Formula: see text] at [Formula: see text]) and compared to state-of-the-art chemical kinetic models. The time-resolved measurements of temperature and number density behind reflected shock waves are utilized to infer the rate coefficients of [Formula: see text] for [Formula: see text], Ar. They are found to be [Formula: see text] and [Formula: see text].

The internet is an information and communication technology that makes it easier for human activities to access data and send information into networks. For industry, the internet is also used to store data both internally and externally. There are several application facilities that are open source to help the industry save data via the internet to the cloud, one of which is the ELK stack. In this research, a simulation of a temperature and humidity monitoring system is designed for a server device factory and simultaneously calculates the amount of production. The data obtained is sent to Elasticsearch as a cloud so that the measurement data can be monitored and visualized in the form of graphs. The system is realized using a microcontroller, ESP8266, DHT11 sensor and proximity sensor. This design is equipped with an ELK system that can collect data and filter the required data so that it can be monitored and visualized in real time. The results of testing the temperature and humidity obtained are in the optimal value range and also proves that this research can be used on a large scale. It is recommended that this design be implemented in a factory or smart home to make it easier to obtain and retrieve the required data.

Authors: Nayak Manoj Kumar , Mishra Biswamohan , Levejoseph Sebastian , Garg Ajay , Sarma Kalyan , Sahoo Biswajit , Tripathi Manjari , Gaikwad Shailesh B. 
Published: February 2024

Objectives:
Neural crest cells (NCCs) are transient structures in the fetal life in vertebrates, which develop at the junctional site of the non-neural and neural ectoderm, sharing a common developmental origin for diverse diseases. After Epithelio-mesenchymal (EMT) of the NCCs within the neural tube, delamination of NCCs occurs. After delamination, the transformation of these cells into various cell lineages produces melanocytes, bones, and cartilage of the skull, cells of the enteric and peripheral nervous system. After the conversion, these cells migrate into various locations of the entire body according to the cell lineage. Abnormalities in neural crest (NC) formation and migration result in various malformations and tumors, known as neurocristopathy.

Material and Methods:
Herein, this case series describes a single-center experience in cephalic NC disorders over the past 3 years, including 17 cases of varying composition (i.e., vascular, dysgenetic, mixed, and neoplastic forms) involving the brain and occasionally skin, eyes, and face of the patients.

Results:
In our study of 17 patients with cephalic NC disease, 6 (35.3%) patients had vascular form, 5 (29.4%) had dysgenetic form, 4 (23.5%) had mixed form, and 2 (11.7%) had neoplastic form. Brain involvement in the form of vascular or parenchyma or both vascular and parenchymal was seen in all of our patients (100%), skin in 6 (35.3%) patients, eye in 2 (11.7%), and face in 1 (5.9%) patient. Treatment was planned according to the various manifestations of the disease.

Conclusion:
Neural crest diseases (NCDs) are a rare and under-recognized group of disorders in the literature and may have been under-reported due to a lack of awareness regarding the same. More such reporting may increase the repertoire of these rare disorders such that clinicians can have a high degree of suspicion leading to early detection and timely counseling and also improve preventive strategies and help in developing new drugs for these disorders or prevent them.

Digital Death
Authors: Lapper Ellen 
Published: February 2024

This paper reflexively unpicks digital ethnographic methods employed during ongoing online fieldwork on ‘digital deaths’. To do so, this research delves into the digital afterlife, exploring the fate of online traces and social media profiles after death, and how social media has changed our relationship with death and grieving. Anthropological studies of online death and grief faced new challenges even before COVID-19 moved research projects online. These include shared vulnerabilities and the ethnographer’s position, online field sites, omnipresent online traces and posthumous personhood, and ethical algorithms and duty to the dead. By transparently detailing my research methods whilst conducting research with Facebook and Instagram users navigating loss, this article contributes an honest and extensive debate on processes, challenges, ethics, and research collaboration. Guided by visual and media anthropology, I advocate for a set of methods rooted in shared anthropology (Rouch 1995) which fosters ongoing dialogue with participants. Thus, this article offers a new perspective on digital death, rooted in collaborative storytelling and reflexive methodologies, facilitating discussions on a still-contentious subject in certain societies. Leveraging the benefits of digital ethnography’s multi-sited nature, the research widens its geographical reach and comments on the sociocultural impacts of digital death.
