Authors: Ibworo Anne , Owenga Jane , Omondi Dickens 
Published: October 2024

Purpose: This study sought to establish the influence of antenatal care counseling on psychosocial adaptation among adolescent mothers in Western Kenya and informed the development of a framework that would enhance psychosocial adaptation.
Method: This health facility-based cross-sectional study was founded on Lazarus and Folkman’s psychosocial coping theory (1986) and Livneh’s psychosocial adaptation to chronic illness and disability framework (2001). It was conducted in three purposively selected County referral hospitals in Western Kenya among 438 sequentially selected adolescent mothers (10-19 years) who had visited antenatal care clinics during antenatal period. Frequency distribution and chi-square analysis were performed to test associations, and correlation (according to Cohen’s guideline of 1988) was included to determine the effect size of counseling provided. Moreover, Multinomial logistic regression (MLR) was run to determine the level of prediction of the variables to psychosocial adaptation (PSA).
Results: Findings indicted that counseling provided for adolescent mothers in Western Kenya did not translate to significant levels of psychosocial adaptation. Specifically, while addressing depression, anxiety child irresponsiveness, and school dropout were significantly associated with respective psychosocial adaptation (p< 0.05), they were weakly correlated (r <.3) and among technical skills employed, only responsiveness and assurance were found to be moderately corelated with self-esteem (r> .3, p< 0.05). Significant predictive variables for the outcome (PSA) from chi square analysis and MLR, occurred singly and not in combination. They included; statistically significant relationship between provision of counseling on child irresponsiveness (x=9.26, df= 1, p=0.002); empathy (x= 5.69, df=1, p=0.017); responsiveness (x= 5.69, df=1, p = 0.005) and self-esteem, while responsiveness (x=17.5, df= 2, p=0.001) and clarity (x= 8.54, df= 2, p <0.014) were significantly associated with societal interaction. In addition, counselling adolescent mothers on acceptance and taking up maternal responsibilities (x=33.12, df=4, p<0.05); assurance (x=10.27, df=4, p=0.036) and responsiveness (x=28.64, df=4, p< 0.05) were found to be significantly associated with love and embrace for child among adolescent mothers. Moreover, Responsiveness exhibited by healthcare workers (HCWs) significantly contributed to love and acceptance for the child (OR, 2.1; 95%CI 0.6 -6.8) and child welfare clinic utilization (OR, 1.7; 95%CI 0.3- 9.2) among adolescent mothers.
Recommendations: Adolescent mothers need individualized and targeted counseling to enhance psychosocial adaptation and which should be integrated into routine antenatal care.

AN EXPRESS METHOD FOR CREATION A FINANCIAL AND ECONOMIC MODEL OF PROJECTS IN THE NUCLEAR ENERGY INDUSTRY BASED ON THE EXAMPLE OF INTENTIONS TO CONSTRUCT A NPP IN THE REPUBLIC OF KAZAKHSTAN

Published: October 2024

Energy is the basis of successful economic growth and society development in general. However, today Kazakhstan is experiencing a shortage of electricity and, according to forecasts, by 2029 it is expected to have more than 3 GW of electric capacity deficit. The introduction of nuclear generation is a perspective solution of electricity shortage issue. Therefore, the construction of a nuclear power plant (NPP) today is one of the key elements on the agenda of our country. In this regard, there is a need for an in-depth analysis and careful consideration of issues related to the NPP construction including financial planning and implementation.Financial and economic modeling (FEM) is the most famous tool for forecasting, planning and management in business. Commonly, some analysis of business ideas begins namely with the FEM, and if the assessments show effectiveness of a business project, then a decision is made on detailed review and funding. It is common practice to construct a fairy complete FEM during feasibility study (FS) of an investment project, when the major design and construction concepts and structural and administrative measures (including financial schemes) have already been defined. Analysis of the model and assessment of financial and economic indicators using FEM allows making a decision on future project developments. In the case of a NPP construction project, where the specific capital costs for the construction of a two-unit station with a total capacity of up to 2.4–2.7 GW are about US$10–15 billion, the financial costs for a feasibility study developing can reach more than US$100 million, and it will take about 3 years to prepare a full feasibility study.The proposed methodology is an express method for developing the FEM of NPP construction projects, which is sufficiently stable with respect to the statistical inaccuracy of some initial data, to determine the financial efficiency of NPP projects. The developed methodology can be used when comparing a large number of NPP construction projects with different initial data in order to quickly select several optimal ones for their detailed study. This paper is relevant considering the adopted course of the Republic of Kazakhstan, as well as many world’s rapidly developing countries, towards decarbonization of the energy sector and industry.
Scaling laws in fluid mechanics: from computational optimization to mathematical analysis
Authors: Wynn Andy 
Published: October 2024

"This talk will consider the problem of how to predict time-averaged statistics of fluid flows as functions of external forcing parameters. For example, in aircraft design, one would like to know the drag on an aircraft’s wing as a function of its flight-velocity; or one may want to know the rate of heat transfer in a layer of fluid as a function boundary heating. Having knowledge of such scaling laws is of fundamental importance in the design of fluid mechanical systems. However, proving rigorous statements is challenging since important flow statistics (drag, heat transfer) depend on the chaotic solutions to nonlinear partial differential equations (Navier-Stokes, Raleigh-Bénard, etc.). A powerful approach to obtaining scaling laws is the so-called background method, popularised by Constantin and Doering in the 1990s, in which emergent flow statistics can be formally bounded by solving variational optimization problems. This approach led to many celebrated fundamental discoveries, most notably for the prediction of convective heat transfer in Raleigh-Bénard convection. This talk will discuss a recent numerical approach to implementing the background method, based on the convex optimization technique of semidefinite programming. We will show how semidefinite programming allows one to derive finite-dimensional optimization problems which rigorously approximate the infinite-dimensional variational problems required to implement the background method. Further, we will discuss how insights gained from the numerical solution to these problems can be used to inspire analytical proofs of scaling laws for several problems in turbulent convection."
Replacing wakes with large-scale streaks in wind farms
Authors: Cossu Carlo 
Published: October 2024

Streamwise streaks are elongated regions of velocity excess and deficit ubiquitous in transitional and turbulent wall-bounded flows. Their prevalence has been explained by linear analyses showing that they are the most amplified disturbances in linearly stable laminar and turbulent shear flows. I will show that wind turbines can be used as "streak generators" to replace the (low-speed) rotor wakes with coherent high-speed streaks. When applied to wind farms, this approach leads to significant gains in the total power extracted from the wind. Maximum power gains are obtained when the transverse spacing of the wind turbines and of the large-scale forced streaks is of the same order as the spacing of the large-scale coherent streaks which are naturally amplified (in the absence of turbines) in turbulent boundary layers.
Enabling Improved Aircraft Performance Through Floating Folding Wing Tips
Authors: Cooper Jonathan 
Published: October 2024

There is much current effort devoted towards achieving net zero emissions from aircraft; however, it will be many years before aircraft are powered by the likes of Sustainable Aviation Fuel, Hydrogen or electrical means. Consequently, any concept that enables reduced fuel burn – and hence generates less emissions – will be extremely beneficial in the short term, and also in the future. This presentation will provide an overview of the work at the University of Bristol relating to the use of floating folding wingtips to facilitate higher aspect ratios (lower drag), meet airport gate restrictions, enable gust loads alleviation and improve roll performance. The talk will refer to many tests that have been performed from blue sky concept demonstrators through to small scale flight tests.
Air quality on trains – aerodynamic interactions of exhaust and HVAC systems
Authors: Soper David 
Published: October 2024

Air quality is known to have significant health impacts from both short- and long-term exposure. As a significant contributor, the transport sector is working to reduce its adverse impact; however, the impact of rail transport on air quality at local levels, particularly within enclosed spaces (e.g. stations and onboard trains), is still not fully understood. With 30% of rail traction diesel-powered, previously studies have shown that in certain conditions pollution concentrations exceed prescribed EU limits in enclosed stations. Although these studies offer insight into issues at particular strategic locations, there have been none which address issues and identify mitigation measures to risks associated with poor air quality for both passengers and train crews onboard trains for typical journeys. This seminar will present work conducted as part of the Rail Safety and Standards Board (RSSB) Clean Air Research programme on project “T1234 Air Quality on Trains - HVAC and Exhaust Interactions Study”, which focused on providing better understanding of rail’s direct contribution to air pollution onboard trains. The project aimed to determine how exhaust emissions and heating, ventilation, and air conditioning (HVAC) systems interact and impact levels of air pollution onboard passenger trains, establishing factors that can be changed to improve air quality. The programme covered a wide range of techniques, from computational studies through to model- and full- experimental validation. Findings indicated that the design configuration of train roofs were particularly important when considering the interaction of exhaust gases with HVAC systems and that simple alterations in design and shape of the roof and exhaust pipe, as well as the HVAC placement and operation could lead to large improvements in onboard air quality

Existence, uniqueness, stability results for tripled system which containing of mixed fractional derivatives with laplacian operator
Authors: Benallou Mohamed , Beddani Hamid 
Published: October 2024

Decades ago, fractional calculus arose to generalize ordinary derivation and integration, and then became a means of modeling and interpreting many phenomena in various fields such as engineering, physics, chemistry, biology and signal processing. The definition of the fractional derivative began with a derivative with a singular kernel, such as the Riemann-Liouville and Caputo derivative. The study of existence and uniqueness of solution of fractional partial differential equations are then proved by mani methods as: the well-known Lax–Milgram theorem, Energy estimate and fixed point theorem... Among them, In this work we investigate the existence and uniqueness of solutions for a new class of tripled system, which containing of mixed fractional derivatives between the Riemann-Liouville and the Caputo fractional derivatives of different orders with Laplacian operator, by using Leray-Schauder alternative fixed point theorem type in generalized Banach space and Banach contraction principle. The stability of the Ulam type of the proposed coupled system is also studied. Due to the importance of variable-order fractional calculus, both from a theoretical and an applied perspective, we think that the results obtained can be of interest to the research pursuits of many readers. At the end, to conclude this paper we provide an example illustrating our findings and approach.
A distributed algorithm for secure dominating set problem in IoT networks
Authors: Lalouci Ali , Farah Zoubeyr 
Published: October 2024

In this paper, we introduce a heuristic-based distributed approach to address the Secure Dominating Set Problem (SDSP) in Internet of Things (IoT) networks. The SDSP is a critical variant of the Dominating Set Problem (DSP), incorporating security and resilience constraints. It involves identifying the minimal subset of nodes that not only forms a dominating set but also ensures that any potential swap within the set preserves its dominating properties. The proposed approach operates in two phases. Phase I involves a spanning tree construction algorithm based on the flooding protocol. In Phase II, we propose a new distributed algorithm called SDSTree, which identifies secure dominating nodes from the spanning tree. We provide a detailed description of the proposed algorithm and analyze its convergence complexity. The performance of the proposed algorithm is rigorously evaluated through simulations using the CupCarbon tool, which is widely recognized for modeling and simulating IoT networks. Compared to an existing method for the DSP in IoT networks, the SDSTree algorithm demonstrates superior performance, achieving faster execution times and requiring fewer message exchanges across various network sizes.
L’attualizzazione dei modelli letterari in «Zwischen neun und neun» (1918) di Leo Perutz
Authors: Ferrari Bedini Giulia 
Published: October 2024

This article analyses the relation between Leo Perutz’s novel Zwischen neun und neun (1918) and the poetics and works of several German-speaking authors who can be considered Perutz’s literary role models. In chronological order, consideration will be given to the enigmatic, paradoxical situations characterising Heinrich von Kleist’s works, to E.T.A. Hoffmann’s serapiontisches Prinzip, irony and humour, and to Arthur Schnitzler’s narratological techniques and the resignation of his characters. The comparison with these models will demonstrate how the novel relates to the tradition of German literature, in what manner it surpasses it and which elements enable its correlation with modernism.

Authors: Liu Yu-Qing , Sun Jian-Liang , Jing Mei , Liu Guo-Xiang , Shi Jie , Zhu Xue-Wei , Wang Fei , Ye Mei-Hua 
Published: October 2024

BACKGROUND
The working environment of submarine crews is also very special. They are in a closed, high-temperature, high-noise, high-vibration and narrow working and living space for a long time, and they suffer from physical discomfort caused by seasickness, which will affect the mental health of officers and soldiers. American psychologists have achieved positive results in psychological resilience training for officers and soldiers from the perspective of positive psychology. At present, there are few reports on the correlation between psychological resilience in the field of domestic research on submarine crew psychology, and it is necessary to conduct further research.
AIM
To explore the impact of active psychological regulation intervention on officers and soldiers operating in confined spaces at sea.
METHODS
A total of 121 soldiers working in a confined space of a large ship were randomly divided into an experimental group and a control group. The 50 soldiers in the experimental group were given a training course intervention, while the 71 soldiers in the control group did not receive any intervention measures. The Pittsburgh Sleep Quality Index, Psychological Resilience Scale, military Psychological Stress Self-Assessment Questionnaire, and General Self-Efficacy Scale scores were compared before and 6 months after the intervention.
RESULTS
Under the positive psychological control intervention, except for sleep efficiency (P = 0.05), the difference between the remaining dimensions of the Pittsburgh Sleep Quality Index scores and the total scores of the experimental group compared with the control group was statistically significant (P < 0.05); the assessment of the psychological condition showed that, in addition to the Psychological Stress Self-assessment Questionnaire for Military Personnel scores (P = 0.05), the scores of the Mental Toughness Scale (Dispositional Resilience Scale Resilience II) in the experimental group, General Self-Efficacy Scale scores were statistically significant (P < 0.05) compared to pre-intervention.
CONCLUSION
Positive psychological intervention and control can improve the sleep state and psychological state of officers and soldiers working in confined space at sea.

Published: October 2024

Streptomyces species are promising resources of bioactive compounds that play a vital role in medicinal biotechnology. Streptomyces sp. SA31 was isolated from the rhizospheric soil of Cymbopogon citratus (DC) Stapf. The strain was identified as Streptomyces samsunensis based on genome-based taxonomic analysis. The draft genome of strain SA31 contained 11,850,342 bp with a high percentage of G+C at 71.0% and carried 9,350 predicted protein-encoding sequences (CDSs). Furthermore, the secondary metabolite biosynthesis gene clusters in the genome of strain SA31 were predicted by antiSMASH. In silico analysis showed 71 predicted biosynthetic gene clusters (BGCs) responsible for antimicrobial secondary metabolite synthesis. Most gene clusters were involved in the biosynthesis of polyketide synthase. The genome of strain SA31 harbored seven types of polyketide biosynthesis gene clusters that might be associated with antimicrobial activity. Additionally, the genome of strain SA31 contained unexplored secondary metabolite biosynthesis gene clusters. In vitro antimicrobial assay showed that an ethyl acetate extract from the culture broth of strain SA31 could inhibit the growth of Staphylococcus aureus ATCC 25923, Kocuria rhizophila ATCC 9341, Bacillus subtilis ATCC 6633, Candida albicans ATCC 10231, and Aspergillus flavus IMI 242684, implying that the genome of strain SA31 contained potential BGCs for the production of antimicrobial secondary metabolites and led to the isolation of geldanamycin and 17-O-demethylgeldanamycin. Therefore, it can be proved that the rhizosphere-associated soil of C. citratus (DC) Stapf. is a rich habitat for actinomycetes that are capable of producing promising biologically active compounds.
