An evaluation of the combustion temperature profile of Ba(NO3)2-based composition
Authors: Nguyen Duy Tuan  , Doan Minh Khai
Published: October 2024

The study examined both theoretical and experimental combustion temperatures of Ba(NO3)2-based samples of composition with an oxidizer excess coefficient of α~0.72 under various pressures. The results indicate that at low pressures, the combustion temperature of the samples is significantly lower than the calculated value. The temperature profile in the combustion wave at atmospheric pressure was determined, revealing that the samples exhibit a high surface combustion temperature. The majority of the heat required for the propagation of the sample's combustion is released in the condensed phase. These findings underscore the influence of pressure on combustion characteristics and emphasize the importance of considering phase interactions in understanding combustion behaviors.

In-depth analysis of scenarios and injuries in crashes between cyclists and commercial vehicles in Germany
Authors: Schindler Ron , Jeppsson Hanna
Published: October 2024

Large vehicles such as buses and heavy goods vehicles (HGVs) pose a serious threat to cyclists and can cause serious injuries. Therefore, it is important to understand current safety issues related to these vehicles, to identify and to develop safety interventions that could address these issues. The aim of this study is to describe the characteristics of and injuries resulting from crashes between cyclists and buses and HGVs. In this study, the German In-Depth Accident Study (GIDAS) was queried for all cases that involved either a bus or a HGV and where the opponent was a cyclist. In total, 98 crashes with the involvement of both a bus and a cyclist, and 295 cases where both a HGV and a cyclist were involved, were identified for our analysis. The crashes with cyclists typically occur within city limits, during daylight conditions, on dry surfaces and with clear weather. The cyclists involved in these crashes are mainly male and cyclists under 18-years old account for 28% of crashes with buses, and 16% for crashes with HGVs. The most common crash scenarios are crossing scenarios and turning-off-a-road crashes. In bus crashes, the collision speeds are mainly below 35 km/h and injuries to lower extremities and head are dominating, caused by the road surface and the front of the bus. In HGV crashes, collision speeds are most often below 20 km/h and injuries to the head and thorax are most common, mainly caused by being run over.
Datafication, Power, and Publics in India's National Digital Health Ecosystem
Authors: Chandrasekhar Ramya
Published: October 2024

While evident for a long time, the COVID-19 pandemic starkly illustrated the need to strengthen India’s public healthcare system. But since 2017, the solution to India’s public health woes takes the shape of the National Digital Health Ecosystem (NDHE) – a digital system for the generation, use, and ‘frictionless’ circulation of health data across healthcare actors through the use of artefacts such as health IDs, electronic health records, data standards, and federated computing architectures. These artefacts are not neutral technological systems. Rather, together with social practices, they constitute a “data infrastructure”. Seeing the NDHE as a data infrastructure allows us to visibilise the regulatory effects of the NDHE, i.e., the ways in which the NDHE creates “communities of the affected” whose access to public health is now mediated by affordances granted by the NDHE. This, in turn, shapes law and regulation of the NDHE, where legal frameworks for (health) data protection are not weakened by accident, but weakened by design. At the same time, the regulatory effects of the NDHE can and should be regulated by law, by channelling law’s commitment to the creation of healthy public spheres to ensure the vitality of a democracy. Accordingly, this paper makes three contributions – one, it provides a brief overview of the political economy and the regulatory effects of the NDHE; two, it analyses the ways in which the regulatory effects of the NDHE shape legal frameworks for health data to disempower individuals and communities who are the generators of this data; and three, it outlines research and policy suggestions for how the law can intervene in limiting the exclusionary data-politics of the NDHE.
Informalisme in de wet: onnodig en riskant
Authors: Raat Caroline
Published: October 2024

Informalism in the law: unnecessary and risky

The childcare benefits scandal in the Netherlands has led to numerous initiatives, including strengthening the Safeguard Function of the Administrative Law Act. One notable aspect of this law is the requirement to include informal resolution of in the appeal procedure, which is based on the concept of psychological procedural justice (PPJ). This theory inspired the project ‘Pleasant Contact with the Government’ (PCMO). While there is nothing wrong with a friendly demeanor, embedding this in law is risky because the justification used by the legislators is scientifically unfounded.

In this article, the author refers to this informality as ‘informalism’: an overly extreme and irresponsible belief in the informal approach, lacking the counterbalance of rule-of-law values. Due to enthusiasm, no research was conducted on the potential side effects and problems of the informal approach, despite their prevalence and explicit warnings to the government. These side effects include unintended arbitrariness and potential integrity issues, which have been extensively studied in sociology of law, public administration, and forensic science. At the end, an alternative is suggested: revaluing quality and objective law.
La batalla de Ayacucho y la construcción del Perú. Entre el mito y la realidad
Authors: Emilio de Diego García
Published: October 2024

El autor nos presenta una serie de consideraciones sobre la batalla "como fin de una época y comienzo de otra, frontera y puente entre dos orillas de la Historia y de su trascendencia que reside en esa doble circunstancia". El 9 de diciembre de 1824 la batalla de Ayacucho marcó un antes y un después en los confines del mundo andino, como acontecimiento militar, soporte de la construcción de un "hecho histórico". A lo largo del artículo se hace una relectura de la contienda entre las fuerzas "realistas" e "independentistas", en la culminación de la campaña de 1824 además de diversos apuntes acerca de la logística, la estrategia, la táctica, la información, la propaganda, las comunicaciones y los recursos al alcance de uno y otro bando, tanto en lo concerniente a los medios humanos y materiales, como las circunstancias del contexto en que se desarrollaron los acontecimientos.

Published: October 2024

The last decade has witnessed a sky rocketing increase in alcohol and drug use, where it is estimated that 39.5 million people have substance use disorders (UNODC, 2023). It is opined that religion in the lives of youth can mitigate against alcohol and substance use, but research indicates that in spite of the religious beliefs, there is still a significant proportion of youth in churches who are involved in alcohol and substance use (National Study of Youth & Religion, 2024). Christian youth grappling with alcohol and drug use are caught in between following that which is biblically acceptable versus the societal norms and culture (Swindell, 2010). Thus, investigating the prevalence of alcohol and substance use among Christian youth, is crucial to pinpointing the causative factors and developing targeted programs. The purpose of this study was to evaluate the prevalence of alcohol/ substance use among Christian youth in four selected churches in Kajiado County, Kenya. It employed a descriptive research design with a sample size of 145 youth (14-35 years;73 male,72 female), who were actively attending Sunday services in the four churches. Data collection utilized the Alcohol, Smoking and Substance Involvement Screening Test- ASSIST- LITE and a socio demographics questionnaire. The data was analyzed quantitatively in SPSS using frequencies and percentages. Findings from the socio demographic questionnaire inquiring on whether respondents ‘had ever used alcohol/substances’ showed that 53(36.6%) of the respondents affirmed that they had ever used alcohol, 12(8.3%) both khat and alcohol, 3(2.1%) khat, hash and alcohol while 5(3.4%) had ever used other substances and alcohol. The ASSIT-Lite inquired on alcohol and drug use in the past three months, where the most frequently used was alcohol at n=42(28.9%), then cannabis at n=27(18.6%), sedatives at n=14(9.7%), stimulants at n=10(6.9%), psychoactive substances at n=6(4.1%) and then opioids at n=3(2.1%). Of the alcohol/substance users, 12(8.3%), 7(4.8%) and 5(3.4%) were at high risk levels for alcohol, cannabis and stimulant use respectively. The study was informative in that, it revealed Christian youth were still grappling with alcohol/substance use, and hence, targeted psychological and behavioral interventions, alongside the church-based programs are necessary.

Authors: Lin Jiashi , Huang Qiqi , Zhong Xinsheng , Zhang Ahua , Lin Peixiang
Published: October 2024

Background: To examine the mechanisms of adaptations in cardiorespiratory fitness with different dose of amount and intensity exercise training in middle-aged men. Methods: A total of 67 sedentary subjects aged 40-49 yr were assigned to participate for 12 weeks in a control group or in one of three exercise groups: 1) low volume/moderate intensity 2) low volume/vigorous intensity and 3) high volume/vigorous intensity. They were tested for VO2max, cardiac output (Q) and stroke volume (SV) before and after training and maximal arterial-venous oxygen difference (a-vO2diff) calculated by the Fick Equation. Results: Contrasted to control group, VO2max increased similar in both LVVI and HVVI groups after 12 weeks; It indicated that the intensity of exercise appears to make a greater benefit than the amount of exercise on VO2max. However, Maximal cardiac output (Qmax) and a-vO2diff contributed to increase VO2max were differences in both of vigorous intensity groups. In LVVI group, Qmax together with maximal a-vO2diff contributed to the greater VO2max; in HVVI group, the majority of the increment in VO2max was relied on larger Qmax whereas a widened a-vO2diff. Conclusion: It is appropriate to recommend vigorous intensity exercise to improve cardiorespiratory fitness and encourage higher amount to confer additional benefit for Qmax.
Is the Cyclic Model of the Universe Possible in the Relativistic Theory of Gravitation?
Authors: Chugreev Yu.V.
Published: October 2024

For the flat FLRW model of Universe evolution in RTG a new model of Dark Energy is proposed. It is a global
scalar field Φ with the quadratic potential. It ensures cosmological acceleration at the present time and a
bounce at the latе times. At the contraction stage Kazner-like growing anisotropy of Riemannian metrics will
break a mass-of- the-graviton bounce mechanism near the Big Bang in FLRW case. There is also noncyclic
option, when small enough graviton-mass-terms are significant only at the end of expansion. After bounce,
during next contraction epoch, an anisotropy grows and the matter density finally reaches the Planck one.
Using Gamma Distribution to Obtain Maxwell–R´enyi Statistics and Other Generalized Distributions
Authors: Nakashidze D. V. , Savchenko A. M. , Bakiev T. N.
Published: October 2024

A universal method is proposed for performing calculations within the framework of generalized statistics
generated by the parametric Tsallis, R´enyi, and Sharma–Mittal entropies. The essence of the approach lies
in the use of an auxiliary gamma distribution whose parameters correspond to a particular variant of the
statistics. Equations are derived that allow the generalised partition function and the mean energy to be
expressed in terms of canonical quantities. The effectiveness of the proposed method is demonstrated using the example of R´enyi statistics. The Maxwell–R´enyi distribution is obtained and its properties are calculated,
based on which assumptions about the possible nature of the generalised parameter are formulated.

Published: October 2024

In this work, a method for evaluating the cross sections of electroproduction of K+Λ and K+Σ 0 off protons
in the region of invariant masses of final hadrons MK + MY < W < 2.65 GeV (MK and MY being
the masses of the kaon and hyperon, respectively) and squares of four-momentum transfers of virtual
photons, i.e., photon virtualities 0 < Q2 < 5 GeV2
, is developed based on experimental data of these
exclusive channels’ cross sections measured by the CLAS detector in Hall B at Jefferson Lab. A set of
algorithms has been implemented to evaluate the differential cross sections of these channels, along with
their statistical and systematic uncertainties. A program was developed for the evaluation of differential
cross sections and structure functions using C++ and Python libraries. An interactive website was created
for working with the program, enabling the analysis of one-dimensional and two-dimensional dependences
of structure functions and differential cross sections. The evaluation of differential cross sections for the
K+Λ and K+Σ 0
electroproduction channels is necessary for extracting the structure function σLT ′ from the
data on the polarization asymmetry of electroproduction reactions of these final states with longitudinally
polarized electrons. The obtained results are also important for the development of realistic Monte Carlo
event generators in planning future experiments and for evaluating the efficiency of detecting final particles
when extracting reaction cross sections from experimental data

Published: October 2024

Solutions in acetonitrile of three mixed complexes of rare earth elements (terbium and samarium) with organic
ligands with various pyridine substituents were studied in this work. The ratios of ligands and metals in the
resulting complexes were determined, and the stability constants of samarium complexes were calculated
using the spectrophotometric titration method. Measurements of absorption, emission and excitation spectra
of luminescence, luminescence kinetics of solutions of mixed complexes of rare earth elements with an excess
of metal relative to the ligand were carried out at various temperatures in the range 298–328 K. An increase
of luminescence intensity of a samarium ion in complex upon heating has been discovered for the first time.
The dependences of the luminescence quantum yield and lifetime of mixed complexes on temperature were
obtained. A thermometric parameter — the ratio of the integral luminescence intensities of samarium and
terbium ions — was proposed, and the temperature sensitivity coefficient of this parameter was determined
for different complexes.

Published: October 2024

Additive manufacturing (AM) is a modern developing group of technologies based not on the removal of
material, but on the layer-by-layer growth and synthesis of an object according to a CAD (Computer-Aided Design) model. The main disadvantages of objects manufactured using AM technologies are a high degree
of porosity and surface roughness. This work examines the possibility of modifying the surface of additive
materials Ti6Al4V and AlSi10Mg using irradiation with Ar+ ions with energies in the range from 2 to 9 keV.
Using SEM, the surface topography was obtained before and after irradiation and mechanical polishing. A
reduction in surface porosity and roughness was demonstrated, as well as the influence of beam energy on
the final surface topography.

Published: October 2024

The widespread use of electronic devices has led to a significant increase in electronic waste, including PCB (printed circuit board) waste. PCBs contain valuable metals like copper and silver, which can be reclaimed and reused. Recently, there has been a growing demand for urban mining processes to extract electronic waste PCB Flame Retardant-2 (FR-2) from laptops and computers. During the urban mining process, PCB FR-2 waste undergoes various physical treatments such as dismantling, crushing, and concentration processes. One of the concentration processes involves magnetic separation using a Davis tube. This study aims to investigate the effects of size and magnetic intensity variations on the recovery of copper and silver levels in FR-2 PCB waste. The magnetic concentration process was carried out using different size ranges (-63+100#, -100+150#, -150#) and magnetic intensities (1000 G, 2000 G, 3000 G). The results indicated that the most effective size for separating copper and silver is -63+100# and the optimal magnetic intensity is 1000 G. This resulted in copper and silver content of 45.66% and 0.162%, with recoveries of 80.135% and 62.505% respectively.

Schweiz, wir haben ein Problem – Benachteiligung in der Bildung
Authors: Schoch Jürg
Published: October 2024

In der Schweiz ist Bildungsgerechtigkeit eine rechtlich und gesellschaftlich deklarierte Intention, jedoch keine Realität. Bildungsverläufe werden nicht nur durch die erbrachte Leistung, sondern auch durch die soziale Herkunft bestimmt. Von Bildungsbenachteiligung besonders betroffen sind Kinder und Jugendliche aus sozioökonomisch benachteiligten Familien mit Migrationshintergrund. Wie steht es aktuell um die Chancengerechtigkeit? Wo liegen die Ursachen für Bildungsbenachteiligung und was könnte zu deren Verbesserung beitragen? Der Beitrag geht diesen Fragen nach, insbesondere am Beispiel von Kindern und Jugendlichen aus sozial benachteiligten Familien.

Als Mitglieder eines Netzwerkes von (heil-)pädagogischen Beratungsstellen, die sich spezifisch der schulischen Förderung von Lernenden im Autismus-Spektrum widmen, beleuchten wir die aktuelle Situation in der Deutschschweiz. Dabei zeigen wir gegenwärtige Herausforderungen und den daraus resultierenden Handlungsbedarf. Im Anschluss formulieren wir Empfehlungen für eine Optimierung der schulischen Förderung für Lernende im Autismus-Spektrum. Wir konkretisieren unsere Empfehlungen anhand von Praxisbeispielen aus zwei kantonalen Beratungsstellen. Wir haben den Beitrag nach einem intensiven Austauschprozess und in kontinuierlicher Absprache mit den Leitungspersonen von zehn am Ende dieses Beitrags aufgelisteten Beratungsstellen verfasst.
Chancengleichheit durch Elterntrainings?
Authors: Niederbacher Edith , Villiger Caroline
Published: October 2024

Im Beitrag wird der Frage nachgegangen, inwiefern ein Elternabend mit einem Elterntraining zum Thema Lernbegleitung zur Chancengleichheit beitragen kann. Im Fokus steht die Frage, welche Elterngruppen (in Bezug auf die Merkmale Geschlecht, Geburtsland, Muttersprache, Bildungsabschluss, Kind mit sonderpädagogischen Massnahmen, Zeit- und Energieressourcen) für einen Elternabend gewonnen werden konnten. Die Ergebnisse zeigen, dass mehrheitlich alle Elterngruppen erreicht werden konnten. Väter sowie im Ausland geborene Erziehungsberechtigte waren jedoch signifikant weniger vertreten. Zudem zeigte sich, dass die Teilnahme der Eltern insbesondere mit deren Zeit- und Energieressourcen zusammenhängt.

The mining industry generates acid mine drainage (AMD) characterized with a low pH value and high dissolved metal concentration that leads to the negative impacts on the environment and human health. The objectives of this research were to investigate the growth response of mixed culture of microalgae Chlorella sorokiniana and Monoraphidium neglectum in a liquid media contaminated with AMD; generate the optimum environmental conditions (pH value and contact time) to determine the efficiency biosorption of iron and manganese contained in the solution of AMD into the consortium of microalgae; and quantify the maximum removal amount of iron and manganese contained in the solution of AMD by utilizing microalgae consortium of Chlorella sorokiniana and Monoraphidium neglectum as biosorbent. AMD used in this research was characterized with a pH value of 1.65 with iron and manganese concentrations of 8.28 mg/L and 4.57 mg/L. The research of biosorption was conducted in 150 rpm with pH level variations of 4, 5, and 6, and contact time variations of 60, 120, and 180 min. The maximum value of iron and manganese removals occurred when pH level reached 5 at 180 min of contact time with removal efficiency of 89.73% for iron and 94.53% for manganese. The results proved that the mixed culture of microalgae namely Chlorella sorokiniana and Monoraphidium neglectum can be utilized to remove iron and manganese contained in acid mine drainage.
Development of Titanium Dioxide Coating for Self-Cleaning Photovoltaic Panels
Authors: Pham Chau , Pung Chris , Jiao Lihong (Heidi)
Published: October 2024

Amid escalating global energy demands and environmental concerns, the transition to renewable sources like solar power is imperative. Despite the advancements in photovoltaic (PV) technology promising increased efficiency, soiling on PV panels—composed of dust, bird droppings, and contaminants—poses a significant challenge, obstructing sunlight and reducing energy conversion efficiency. Building upon existing research on titanium dioxide (TiO2) nanoparticle coatings, our study investigates their super-hydrophilic and anti-soiling characteristics to enhance self-cleaning capabilities in solar applications. Furthermore, our research investigates the application of (3-aminopropyl)trimethoxy silane as an interlayer to reinforce the adherence of the TiO2 coating to PV panel glass, thereby enhancing its durability. Preliminary results highlight the coating’s exceptional super-hydrophilic properties, with water contact angle measurements less than 10°, indicative of TiO2’s strong water affinity. Spectrophotometer measurements show that the developed coating maintains high optical transmittances for the wavelength range from 350 to 800 nm, which is the most crucial factor for energy conversion in solar panels. Our contributions aim to advance solar energy technologies and support the shift towards more sustainable energy solutions, highlighting the role of innovative materials science in addressing solar power’s operational challenges.
Early Period Survival and Neurologic Prognosis in Newborns with Perinatal Asphyxia: A Tertiary Center Experience and a Mortality Chart
Authors: Yaman Akan , Kandemir Ibrahim , Alp Unkar Zeynep
Published: October 2024

Background: Clinicians require more data regarding mortality and brain damage risk factors in perinatal asphyxia. Objectives: To assess early term outcomes and identify mortality risk factors in perinatal asphyxia. Methods: This study was conducted in a referral-center tertiary intensive care unit in Istanbul, Turkey, between 2016 and 2023. We included all patients who underwent therapeutic hypothermia treatment due to perinatal asphyxia. We recorded laboratory follow-up data, magnetic resonance imaging (MRI) findings, amplitude-integrated electroencephalograms (aEEG) results, mortality, and clinical outcomes. Both conventional frequentist statistical methods and Bayesian methods were used for analysis. Results: A total of 164 patients were included in the study, with an overall mortality rate of 9.8%. Risk factors for mortality included LDH, troponin I, INR, lactate, 2nd day creatinine, voltage anomalies, seizures, and male gender, as well as APGAR scores. A basic chart for mortality prediction was developed. The Sarnat score showed strong evidence, and APGAR 1 showed anecdotal evidence for association with brain damage, although brain damage was independent of laboratory results and other clinical findings, based on moderate and anecdotal evidence from Bayesian calculations. Cranial MRI findings revealed profound damage in 14.8% of Sarnat 1, 21.8% of Sarnat 2, and 50% of Sarnat 3 patients. Conclusions: This study presents prognostic factors for survival and brain damage in perinatal asphyxia. We recommend obtaining cranial MRI for all patients diagnosed with asphyxia, as most laboratory tests were independent of brain damage. Given that profound brain damage can occur even in Sarnat stage I patients, we emphasize the importance of therapeutic hypothermia for these patients.
