Abstract
Designing a DWDM system for fiber optic transmissions requires optimizing some important parameters to enable the system to be more tolerant to nonlinear impairments. This paper proposes a simulation of a 32-channels system with different bit rates per channel, for different modulation formats (RZ, NRZ, 4-QAM, and DQPSK) then the Gaussian (Gauss) and Hyperbolic Secant (Sech) pulses. The main goal is to investigate the resilience of the designed system to nonlinear effects, taking into account the different modulation formats and bit rates used. Thus, several comparisons were taken into account in the different simulations carried out with the optisystem software. The results reveal that for a bit rate of 40 Gbps per channel, the order of performance is NRZ, Sech, 4-QAM, RZ, and DQPSK; whereas for a bit rate of 100 Gbps per channel, the order becomes NRZ, DQPSK, 4-QAM, Sech, and RZ. For a bit rate of 100 Gbps without nonlinear effects, the 4-QAM format would be more efficient than other modulation formats for the input powers considered (−10 dBm to 10 dBm). While this same 4-QAM format is more vulnerable to nonlinear effects beyond an input power of 5 dBm. At a bit rate of 100 Gbps, the DQPSK format would be more resilient to nonlinear effects for input powers between −10 dBm and 8 dBm for the simulated system.

Abstract
A metallic alloy is a combination of two or more elements, often called a compound or a solution. Steel is largely composed of carbon, a nonmetal, but alloys are often made up of metals. In this article, the authors have explored the electrically conducting water-based viscous nanofluids flow past a rotating disk surface. The nanofluids flow is composed of titanium and aluminum alloys where water is used as a base fluid. Two important cases, namely the stretching case and the shrinking case, were investigated to analyze the flow behaviors due to the different embedding factors. The impacts of viscous Joule heating, thermophoresis, Brownian motion, activation energy, nonlinear thermal radiation, and chemical reaction are investigated here. By employing an appropriate set of variables for shifting the leading equations to dimension-free form. The mathematical model is solved numerically by incorporating the bvp4c MATLAB scheme. Current work is validated with previous studies. The outcomes showed that the radial velocity increases when the disk surface stretches and reduces when the disk surface shrinks. On the other hand, the Azimuthal velocity increases when the disk surface shrinks and reduces when disk surface stretches. Both the radial and Azimuthal velocities are the diminishing functions of the magnetic factor, whereas temperature is the growing function of magnetic factor. In addition, the temperature is more influenced by the magnetic factor in the case of nonlinear radiation. The higher magnetic factor increases skin friction. In addition, the stretching case experiences more surface drag than the shrinking case. It is found that nanofluid flow containing titanium alloy has perceived the greater impacts of the embedded factors compared to the nanofluid flow containing aluminum alloy.

Published: February 2024

Abstract
The present paper discusses about the method developed for complete chemical characterization of Zirconium Washed and Dried Frit (WDF) and Reactor Grade ZrO2 powder which includes nonmetallic element sulphur using Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). Studies have been carried-out on several important aspects of method development such as effect of matrix on determination of analytes, removal of matrix using different solvents, selection of interference free & sensitive wavelengths, calibration strategies like internal standard & standard addition, optimization of several instrumental parameters which includes RF power, plasma gas flow, nebulizer gas flow, nitrogen purging etc., and are discussed. A % RSD of less than 1 % for Zr and up to 3 % for other elements has been achieved in this method. The developed method has been validated using standard recovery of spiked real time samples with known amount of reference materials. Integrated approach adopted in the development of this method has resulted in reduction of analytical waste generated and also enabled to give quick analytical feedback to production plant for downstream processing.

Published: February 2024

Abstract
Childhood epilepsy affects up to 1 % of children. It has been shown that 30 % of patients are resistant to drug treatments, making further investigation of other potential treatment strategies necessary. One such approach is the ketogenic diet (KD) showing promising results and potential benefits beyond the use of current antiepileptic drugs. This study aims to investigate the effects of KD on inflammation and oxidative stress, as one of the main suggested mechanisms of neuroprotection, in children with epilepsy. This narrative review was conducted using the Medline and Google Scholar databases, and by searching epilepsy, drug-resistant epilepsy, child, children, ketogenic, ketogenic diet, diet, ketogenic, keto, ketone bodies (BHB), PUFA, gut microbiota, inflammation, inflammation mediators, neurogenic inflammation, neuroinflammation, inflammatory marker, adenosine modulation, mitochondrial function, MTOR pathway, Nrf2 pathway, mitochondrial dysfunction, PPARɣ, oxidative stress, ROS/RNS, and stress oxidative as keywords. Compelling evidence underscores inflammation and oxidative stress as pivotal factors in epilepsy, even in cases with genetic origins. The ketogenic diet effectively addresses these factors by reducing ROS and RNS, enhancing antioxidant defenses, improving mitochondrial function, and regulating inflammatory genes. Additionally, KD curbs pro-inflammatory cytokine and chemokine production by dampening NF-κB activation, inhibiting the NLRP3 inflammasome, increasing brain adenosine levels, mTOR pathway inhibition, upregulating PPARɣ expression, and promoting a healthy gut microbiota while emphasizing the consumption of healthy fats. KD could be considered a promising therapeutic intervention in patients with epilepsy particularly in drug-resistant epilepsy cases, due to its targeted approach addressing oxidative stress and inflammatory mechanisms.
Disease mongering, overdiagnosis, and media practices: a critical discourse analysis of sluggish cognitive tempo (SCT) and the motivational deficiency disorder (MoDeD) spoof
Authors: Heaney Dermot , Riboni Giorgia 
Published: February 2024

Abstract
This paper explores ways in which the strategic use of discursive and generic conventions has the potential to create a non-existent pathology and mislead the public. This case study compares and examines datasets of different genres (newspaper issue reports, online videos, and Wikipedia pages) dealing with a condition considered as an actual illness (Sluggish Cognitive Tempo, SCT), and another (Motivational Deficiency Disorder, MoDeD), invented as a spoof to raise awareness about disease mongering, overdiagnosis, and medicalization. We evince common language strategies that, irrespective of the genre, can be employed in media discourse, both in the name of genuine medical information and in pursuit of more ethically questionable ends. The methodological tools provided by Critical Discourse Analysis are applied to both the authentic and the hoax texts in order to investigate the media representations of SCT and MoDeD, juxtaposing the ways in which both are framed conceptually, defined linguistically, and popularized to lay audiences. The findings indicate the existence of a common repertoire of lexical-phraseological, rhetorical and discursive patterns that typify the popularization of medicalized statuses and combine to increase the persuasiveness and authority of overdiagnosis, ultimately advancing the case for medicalization with the public at large.

Ketelhut, S, Ketelhut, K, Ketelhut, SR, and Ketelhut, RG. Effects of school-based high-intensity interval training on hemodynamic parameters and heart rate variability: A randomized controlled trial. J Strength Cond Res XX(X): 000–000, 2023—The purpose of this study was to assess the effects of a child-specific school-based high-intensity interval training (HIIT) implemented into physical education (PE) classes on various hemodynamic parameters and heart rate variability indices. Forty-six students (age 11 ± 1 year) were randomized into an intervention (INT n = 22) and a control group (CON n = 24). During a 12-week period, the INT and CON groups participated in regular PE twice weekly (45–90 minutes). The INT group received HIIT during the first 20 minutes of the 2 PE classes. Systolic and diastolic blood pressure, total peripheral resistance, aortic pulse wave velocity (aPWV), heart rate, SD of normal to normal heartbeat intervals, the root mean square of successive differences between normal heartbeats (RMSSD), the proportion of differences between adjacent normal to normal heartbeat intervals of more than 50 ms, low-frequency power, high-frequency power, and the LF/HF ratio were assessed before and after the experimental period. A p value ≤0.05 was considered statistically significant. Forty students (20 INT; 20 CON) were included in the analysis. A significant time × group interaction was detected for aPWV (p = 0.05, η

2
= 0.099), RMSSD (p = 0.010, η

Changing the balance of forces in the supplier-consumer pair
Authors: Pleshchenko V. I. 
Published: February 2024

Building long-term and mutually beneficial relationships between suppliers and consumers is one of the important issues considered when studying the commercial activities of industrial enterprises and, in particular, the procurement process of goods, works, services which are necessary for the smooth and rhythmic functioning of production complexes.The article provides a classification analysis of the relationship between the parties in the “supplier-consumer” pair from the standpoint of assessing their business activity and bargaining power, four main groups are identified and characterized by signs: active, passive, strong, weak.Further, the main elements of the new market reality for suppliers and consumers, formed under the influence of the consequences of the coronavirus epidemic and the sanctions imposed on Russia, are analyzed. As an important effect of the events taking place, the strengthening of the bargaining power of suppliers, the increase in the degree of their influence on the price conjuncture of commodity markets was noted. Based on a functional analogy (a linear function is used in the consideration), it is shown how suppliers shift their noticeably increased costs to buyers, who, in turn, due to inertia, are not immediately ready to accept the new realities. The search for alternative options to meet the needs is currently much more difficult. All this leads to a delay in the negotiation process, lengthening the deadlines for the implementation of projects, reducing the efficiency of production and economic activities. The solution of emerging problems cannot be fast, requires intensive communication with potential suppliers from friendly and neutral countries, as well as active involvement of industrial consumers in import substitution processes.
The Earthquake Fatality Load: A Measure of Impact
Authors: Wyss Max , Speiser Michel , Tolis Stavros 
Published: February 2024

ABSTRACT
A key measure of the earthquake problem in a country is the ratio of fatalities to population size. We propose that the new parameter earthquake fatality load per year objectively measures the level of the population suffering in seismically active countries, that is, it indicates the average annual cost in lives. We present a list of this new parameter for 35 seismically important countries with adequate data for this estimate. Among these countries, Ecuador, Lebanon, Haiti, Turkmenistan, Iran, and Portugal have experienced the greatest loads during the last five centuries. The earthquake fatality load decreases significantly as a function of time in the 18 countries with enough data for analysis. Major factors causing this may be improved resistance to shaking by the built environment, and migration of the rural population leaving weak buildings and occupying stronger ones in large cities.

Published: February 2024

Introduction. Today, the concept of management has become increasingly complex. Many medical-social organisations now help to understand this complexity, enabling managers to support executives throughout their medical-social work.Aim. The aim of the present research is to explore the correlations between managerial aspects in medico-social organisations in order to understand their links and identify avenues for improvement to increase operational efficiency and quality of care.Methodology and research methods. The authors employed a quantitative approach, based on a correlational study rather than an experimental one. The sample consisted of 100 Medical-Psycho-Pedagogical Centres (CMPP) in the Ile-de-France region, France. To collect the information, the directors of these centres were invited to fill in the questionnaire sent by the Google Forms platform, via the e-mail addresses of each centre. The results were processed with IBM SPSS 29.Results and scientific novelty. The results showed that there were statistically significant correlations between the managerial criteria of a high and significant percentage. There was a very high level of significance between the aspects “Structure and team management” and “Patient data management” (98%), and between the aspects “Quality and safety of care” and “Structure and team management” (91%). As for “Inter-professional cooperation” and “Quality and safety of care” aspects, this was significant at 70%. Finally, the aspects “Accessibility and continuity of care”, and “Continuing education” correlate significantly at 85%.In sum, the findings demonstrate that, out of the 22 correlations that were computed, 20 relationships are significant (i.e. 90.90% of the relationships), attesting to the superior management structure of French centres.Practical significance. The contribution of the present study consists in identifying the dimensions of managerial aspects described in the review of management literature. Of course, the purpose of this work is not to justify one style or to privilege one style over another, but to contribute to the explanation of the reality of the management of health, social and medico-social establishments and to take them as a system to be followed in the management of CMPPs in Morocco.

Published: February 2024

Anaemia in pregnancy is a public health problem in developing countries. An observational study of anaemic pregnant women was carried out at the Department of Obstetrics and Gynecology from 1st December 2015 to 30th may 2017, to determine the effects of maternal anaemia on the newborn babies according to the severity of anaemia. 314 pregnant women with anaemia were included in this study. Parameters studied were haemoglobin levels, neonatal birth weight, APGAR score, NICU admission and cord blood haemoglobin. Severity of anaemia is determined by additional cutoffs, with severe anaemia defined as a haemoglobin level of less than 7.0g/dl. Statistics 16.0 software was used. Out of 314 patients, 24 patients (7.6%), 39 patients (12.4%), 251 patients(79.9%) were in severe, moderate, and mild category respectively. Mean haemoglobin levels in present study was 8.65gm/dl. 219 newborns (69.7%) were low birth weight out of which 100% babies born to severely anaemic mothers were LBW which shows that with increase in severity of anaemia, birth weight decreases which is statistically significant. 91.7% babies born to severe category had less than 7 APGAR score. 91.7% newborn in severe anaemia were admitted to NICU. 87.5% babies born to severely anaemic women had neonatal anaemia. Anaemia during pregnancy and its management remains an important issue in perinatal medication. Correct diagnosis and treatment lead to effective management of fetal and maternal risks and improved perinatal outcome.

Abstract
Brown carbon (BrC) is a new term for organic aerosol (OA) with strong absorption ability from the vis to UV wavelengths, which plays a vital role in atmospheric visibility and climate change. Herein, we report field measurements from 1 March 2020 to 28 February 2021, sampled at the urban Suzhou, Yangtze River Delta (YRD), China, to investigate the optical properties and sources of BrC. The light absorption of BrC was found to be highest (babs370=9.0±7.2 Mm-1) in winter and lowest (babs370=5.1±3.3 Mm-1) in summer, respectively. The AAE value of BrC in winter was 1.22±0.05, followed by 1.21±0.05, 1.20±0.05, and 1.19±0.05 for fall, spring and summer, respectively. The MAC of secondary organic carbon (SOC) was 3.3±0.2 m2g-1 in spring, 2.9±0.1 m2g-1 in summer, 4.3±0.1 m2g-1 in fall and 2.8±0.2 m2g-1 in winter, significantly lower than that of primary organic carbon (POC) (12.1±0.3 m2g-1 in spring, 10.2±0.2 m2g-1 in summer, 13.6±0.3 m2g-1 in fall and 10.7±0.2 m2g-1 in winter) at 370nm, suggesting photochemical oxidation could weaken the light absorption of aged BrC. Five different BrC sources were identified by Positive Matrix Factorization (PMF), including a biomass burning-related, a vehicle-related, a sulfate-related, a nitrate-related, and a dust-related source, which averagely contributed 7.4%, 73.4%, 11.9%, 1.9%, and 5.4% to babs370. The Potential Source Contribution Factor (PSCF) analysis showed that high polluted period was mainly contributed by air mass from the south. Besides, the influence degree of the potential source areas, the sequence was winter > spring > fall > summer. Our results improve the understanding of BrC in an important industrial city in YRD, which could reduce the uncertainty of the prediction of its climate effect in this region.
