Authors: Kuzmina E , Sambu-Hoo Chechena , Mongush Liliya
Published: January 2025

For agriculture of the Republic of Tuva, animal husbandry has always been the leading industry, which is facilitated by the natural and climatic conditions of the region. The territory of the republic is divided into 4 agricultural zones according to the geographical location, taking into account climatic features, terrain, soil cover, vegetation. The purpose of research was to analyze the current state and prospects for the development of the animal husbandry industry of the Republic of Tuva in the context of natural and climatic agricultural zones. It was determined that the largest number of cattle and horses is currently concentrated in the central zone (42.1 and 42.0 %), followed by the western (35.0 and 31.3 %) and southern (19.5 and 24.4 %) zone. About half of the total number of small cattle (45.3 %) is kept in the southern zone, in the central and western zones – 27.6 and 26.6 %, respectively. For the central zone, which has the largest arable land and large areas of steppe, forest-steppe, foothill, mountain pastures, it is effective to develop dairy and beef cattle breeding, early maturing meat and wool, semi-coarse and fine-wool sheep breeding, wool goat breeding, and horse breeding. In the western zone, characterized by a more severe climate, about half of the pastures of the republic are located, which creates conditions for breeding dairy and beef cattle, semi-coarse and coarse-wooled sheep, woolly goats, horses, yaks in some areas of the zone. The southern zone of dry steppes is optimal for breeding beef cattle, coarse-wooled and semi-coarse-wooled sheep, goats, both woolly and coarse-haired horses. The main branch of animal husbandry in the eastern mountain-taiga zone is reindeer breeding.

Authors: - Blaise FYAMA , - Ruphin NYAMI NYATE
Published: January 2025

Nowadays, the need for a powerful model in the task of accurate image classification is increasing. This paper focuses on evaluating and comparing the effectiveness of three main neural network models namely the multilayer perceptron model, convolutional neural networks and the transfer learning model for the classification of mineral and rock images in the mining region of Katanga. The main problem addressed is the identification of the most efficient and accurate machine learning techniques in the specific classification of mineral images, with a particular focus on the constitution of the dataset, the analysis of mineral image data and their associated labels. Parameters such as the burial lot, the number of cycles, the size of convolution filters, the precision and the loss have been taken into account. The results show that the transfer learning-based model significantly outperforms the multilayer perceptron models and convolutional neural networks in terms of accuracy and robustness, achieving a classification accuracy of 97.8% compared to 75% for the multilayer perceptron and 96% for the convolutional neural networks designed from scratch. These remarkable results demonstrate the importance of deep learning in processing complex images and open new perspectives for the use of these techniques in the mining sector of the Greater Katanga mining region in the identification of mineral resources. The broader implications of this study include an innovation in mining exploration strategies through faster and more accurate classification of minerals, thus influencing both economic decision-making and environmental policies associated with mining in the region.

Authors: Hasan Haryati , Ilham Hussin Nafisah
Published: January 2025

Undang-undang mengenai pelacuran sangat penting untuk mengawal kegiatan pelacuran, tetapi penelitian yang mendalam berkenaan undang-undang ini masih belum sempurna dilakukan. Hal ini dikatakan demikian kerana masih banyak perkara yang berhubung dengan undang-undang ini yang masih belum diteroka dan dibahaskan. Oleh itu, pengkaji membincangkan undang-undang mengenai kegiatan pelacuran di Malaysia dengan menganalisis sumber primer dan sumber sekunder yang terdiri daripada Akta, laporan bertulis, Majlis Agama Islam dan Istiadat Melayu Kelantan, jurnal, buku dan tesis. Perbincangan dibahagikan kepada dua bahagian. Bagi bahagian pertama, pengkaji membincangkan jenis akta yang digunakan di Malaysia bagi mengawal kegiatan pelacuran. Dalam hal ini, pengkaji memfokuskan Akta Perlindungan Wanita dan Gadis 1973, kekuatan dan kelemahan akta ini dan beberapa akta lain yang berkaitan. Bagi bahagian kedua, pengkaji membincangkan jenis undang-undang bagi mengawal kegiatan pelacuran di Kelantan yang terdiri daripada Notis, Pemberitahu dan Cadangan. Dapatan kajian menunjukkan bahawa undang-undang ini masih belum mampu menangani masalah pelacuran di Malaysia secara amnya dan di Kelantan secara khususnya. Oleh itu, kawalan yang bukan berbentuk undang-undang daripada pihak kerajaan, badan bukan kerajaan dan masyarakat perlu bergerak seiring dengan undang-undang sedia ada.

Authors: Hamid Noor ‘Ashikin , Harun Noraida
Published: January 2025

Legitimasi dalam konteks undang-undang keluarga Islam merujuk status sah atau tidak sah seseorang anak dalam sebuah perkahwinan berdasarkan undang-undang Islam. Legitimasi menentukan nasab anak, sama ada yang dilahirkan dalam tempoh perkahwinan atau luar tempoh perkahwinan. Perkara yang membezakan antara anak tidak sah taraf dengan anak sah taraf ialah kaedah penentuan nasab dan hak yang dimiliki oleh anak sah taraf. Anak tidak sah taraf tidak boleh dinasabkan kepada bapanya walaupun bapa biologinya. Dalam hal ini, anak itu tidak boleh mewarisi harta, mendapat nafkah atau berada di bawah jagaan bapanya. Kesannya, anak ini mungkin berasa terpinggir dan rendah diri. Kajian ini dilakukan untuk meneliti hak yang diperoleh oleh anak tidak sah taraf. Dalam kajian ini, turut dibincangkan kaedah penentuan nasab dan dicadangkan cara untuk menjelaskan hak tersebut. Kajian ini berbentuk kualitatif melalui kaedah penyelidikan perpustakaan, iaitu bahan yang dianalisis secara kritis. Pengkaji mendapati bahawa terdapat tiga kaedah utama dalam penentuan nasab, dan anak pula, sama ada yang sah taraf atau yang tidak sah taraf, mempunyai hak yang dilindungi di bawah undang-undang Islam, begitu juga undang-undang keluarga Islam di Malaysia.

Published: January 2025

This article provides a comprehensive analysis of conflicts in professional education and the methods and approaches to resolve them. It is well-known that conflict situations are quite common in professional education. These include conflicts between teachers and students, teachers and parents, and among students themselves. Each situation is critical and significant. Students in professional education are like budding flowers. Such situations can have a negative impact on their minds since they are not yet able to form independent opinions. They are always influenced by external factors, which can sometimes be negative and sometimes positive. It is well-established that conflict situations are closely connected with the science of psychology.

Rare finds of the coiled cephalopod Discoceras from the Upper Ordovician of Bornholm, Denmark
Authors:   Museum Mors, Fossil- og Molermuseet, Denmark, Rasmussen Jan Audun , Surlyk Finn ,   Department of Geography and Geology, University of Copenhagen, Denmark.
Published: January 2025

Coiled nautiloid cephalopods of the genus Discoceras are locally common in the Middle and Upper Ordovician of Baltica, for example in the Oslo Graben, but are exceedingly rare in contemporaneous strata from the Danish island of Bornholm.
The two new species of Discoceras described here, D. costatum n. sp. and D. vasegaardense n. sp., occur in shales of the Upper Ordovician Lindegård Formation. The nautiloids are preserved as external molds in laminated siliciclastic mudstones.
The very rare occurrence of cephalopods, combined with the apparently endemic nature of the Discoceras fauna, may be explained by the location of Bornholm distally on the Baltoscandian shelf combined with the influence of relatively cold ocean currents from the adjacent Rheic Ocean.

Published: January 2025

Background. Acute ischemic stroke (AIS) requires efficient thrombolytic therapy to re-establish vascular permeability and mitigate tissue damage. Alteplase and tenecteplase are prominent tissue plasminogen activators (tPAs) employed in this clinical scenario. This study compares these two agents, focusing on their efficacy, safety profiles, time parameters, and rates of re-hospitalization. Objectives. To compare the efficacy and safety of tenecteplase versus alteplase for treating acute ischemic stroke in South Indian patients: a prospective study. Methods. At a single center, we conducted a prospective, observational, non-interventional study of patients receiving thrombolytics alteplase or tenecteplase from November 2023 to July 2024, which included patients within a 4.5-hour window of symptom onset. The principal outcome of this study is to evaluate early neurological improvement using the clinical assessment scales – the National Institutes of Health Stroke Scale (NIHSS) at baseline and 24 hours, and the Modified Rankin Scale (mRS) at admission and 3 months. The secondary outcomes include the door-to-needle time (DTN) and assessing the need for re-hospitalization. Data was scrutinized using a t-test and median interquartile range (IQR). Results. The study enrolled 64 patients, 32 treated with alteplase and 32 with tenecteplase. Statistical significance was found for the efficacy of the drugs (NIHSS post-treatment p = 0.01 and mRS p = 0.002). The DTN and re-hospitalization were found to be non-significant. Conclusion. Both alteplase and tenecteplase efficiently manage AIS, with tenecteplase demonstrating advantages in early neurological improvement, ease of administration, and cost-effectiveness.
Performance Analysis of Three Phase Cascaded H-Bridge Multilevel Inverter Design for Solar Power Plant Optimization
Authors: Widagdo Reza Sarwo , Slamet Puji , Hariadi Balok
Published: January 2025

An inverter is an electrical device that converts direct current (DC) into alternating current (AC). Typically, a standard inverter operates at three voltage levels: +Vdc, -Vdc, and 0. However, a multilevel inverter consists of several smaller inverters connected in a series to produce multiple voltage levels at the output. The primary advantage of this type of inverter lies in its ability to produce a much lower harmonic distortion compared to traditional, non-multilevel inverters. Additionally, the switching components of a multilevel inverter operate at lower frequencies, which makes it more suitable for highpower applications. This research focuses on a threephase cascaded multilevel inverter, specifically generating output waveforms with up to seven levels. The study involves conducting experiments using RL loads, to observe how these variations affect the output waveforms and their harmonic distortions. The result, THDi values are much lower, with the 3rd harmonic contributing 0.02%, the 5th contributing 0.006%, the 7th contributing 0.004%, the 9th contributing 0.002%, the 11th contributing 0.002%, and the 13th harmonic contributing just 0.001%. These results suggest that the voltage harmonic more significant harmonic distortion than the current, particularly at the 13th harmonic order. This increase highlights the effect of inductive loads on the performance of the inverter, particularly in terms of harmonic content. These findings are crucial for optimizing multilevel inverters in practical applications, ensuring improved performance and efficiency.
Jesus uttering his last words and drawing on his final breath: reflecting on Luke 23:46
Authors: Nagel P.
Published: January 2025

The last words and final breath of any human being in the wake of death is a moment in time one should not underappreciate. The death of Jesus certainly falls into the category of a human being taking a final breath while uttering last words. If these statements are afair assessment, then it is reasonable to reflect on the existential value and significance of Jesus’ last words and final breath. To state the obvious, his death, as a central figure within Christianity, holds potential theological value and significance for how millions interpret their final moments. His death also possesses existential value for obvious reasons. There is thus a substantial theological burden on what his death means, the impactit has on those “believing” in him, and the consequences for all those who consider their death as dying “in him”.  This study does not overburden Jesus’ last moments with theological concerns but aims to reflect on Luke 23:46 and parallels from an existential-anthropological point of view. It deliberately accentuates the mundane, “human” character of Jesus’ “last” moments on this earth. The purpose of this reflection is to come to a deeper appreciation of his death, with the hope that it might mean something to someone struggling to breathe while dying.
Cur Deus Homo vs Homo Deus and the Evolution of Humanity: Quo Vadis?
Authors: Langerman P.
Published: January 2025

This article deals with the profound shifts that are taking place in light of the Fourth Industrial Revolution, in whichhumanity’s future is highly topical. The article engages Thomas Merton’s re-evaluation of Anselm’s Cur Homo Deo with Harari’s book Homo Deus (2015) and argues that, while we must take Harari’s views seriously, thefuture evolution of humanity is not the human godsuggested by Harari, but that suggested by Merton, who argues that the incarnation shows God’s love for creation; shows Christ as the pattern of what it means to live a holy life, and, ultimately, shows the future of both the cosmos and humanity, where all is taken into the very heart of God. Harari views the future as the creation of a benevolent human god; Merton views the future as a place where all of creation is divinised.
Jesus talks to the Samaritan woman
Authors: Rule P.
Published: January 2025

The contemporary world is characterised by the dehumanisation of “the other” on multiple grounds. Jesus’ encounter with the Samaritan woman (John 4:1-42) sheds light on his attitude towards, and his engagement with her as a conventional “other” for Jews. This article aims to explain their dialogic encounter as an informal teaching and learning event against the backdrop of Jew-Samaritan relations and the status and roles of women in New Testament times. It uses the conceptual framework of diacognition, drawing on the notions of dialogue, position, and cognition to conduct an analysis of the episode as a learning event. It finds that the encounter enables the Samaritan woman to recognise Jesus asprophet and Messiah and transforms her conventional female positions to those of partner in dialogue, agent,and apostle. It thus challenges the “othering” of outsiders in contemporary church and society and affirms the leadership and agency of women.

Published: January 2025

Zinc (Zn) has long been considered as an indispensable micronutrient for crop production and its deficiency is now well established in Pakistani soils. We conducted a field study to evaluate the Zn use relations of five advanced wheat lines, viz. IV-1, IV-2, NARC-2, PAK-13, and V-119 under Zn-deficient soil conditions as affected by the application of 5.0 kg Zn ha⁻¹. The study involved three complete blocks with properly randomized treatments. Application of 5.0 kg Zn ha-1 significantly improved traits such as shoot and root fresh weight (61% and 68%), dry weight (50% and 39%), shoot and root length (77% and 74%), shoot and root Zn concentration (72% and 75%), Zn accumulation (35% and 27%), and Zn-use efficiency (69%). Among the wheat lines, NARC-2 and V-119 demonstrated efficient-responsive characteristics under both Zn-deficient and sufficient conditions. NARC-2 was highly responsive for the biomass production (both shoot and root) and Zn-use efficiency, while V-119 excelled in shoot and root length, Zn concentration, and Zn-use efficiency. IV-3 was the most efficient line under Zn-deficient conditions, showing superior tolerance and a high Zn-efficiency ratio, but was less responsive under sufficient Zn. PAK-13 was highly responsive under sufficient Zn, particularly for Zn-use efficiency, but less effective under deficiency stress. Our findings conclude that zinc nutrition significantly affected biomass production and zinc dynamics of wheat lines at the early growth stage. The NARC-2 and V-119 were found to be the most promising wheat lines for both Zn-deficient and sufficient conditions, with NARC-2 emerging as the most efficient-responsive wheat line. Further research is recommended to validate these findings.

Published: January 2025

Humic substances have many beneﬁcial eﬀects on soil and plant growth. The peat is an accumulation of partially decayed organic matter that can be used to isolate humic acid from it. The objective of this study was to prepare humic acid from peat soil and determine its eﬀects on maize plant growth in order to consider their agricultural use as organic fertilizers. The isolation and purification of humic acid (potassium humate) from peat soil of Kuala Tatau (Sarawak, Malaysia) was performed in the Ddepartment of Land Management, Universiti Putra Malaysia. A glasshouse experiment was conducted to study the efficacy of prepared humic acid of peat soil (HAPS) by comparatively evaluating it with a commercial humic acid (HAC). Different levels of both humic acids were mixed with macro and micronutrients and applied on maize crop to observe their effect on growth and nutrient uptake in acid soil. There were eleven treatments with different combinations of HAPS and HAC. The positive eﬀects of both humic acid sources were observed on the whole plant growth. The maximum plant height among all treatments was recorded in plots where HAPS along with NPK and CuSO4 were applied. The thickest stems and the highest number of leaves were recorded in the plants which received HAPS + NPK + CuSO4 + ZnSO4. The same trend was observed in the enhancement of total plant dry weight and root dry weight of maize plant. The highest yield was recorded in treatment 9 (HAPS +NPK+ CuSO4 + ZnSO4). Although both types of humic acid increased the crop yield, but HAPS gave significantly better results. This study highlighted that humic acid prepared from peat soil is a worthwhile practice with enormous benefits for soil and crops.

Published: January 2025

Exploring the effects of row spacing is of crucial significance to achieve the economically optimum achene yield and oil content of sunflower. We conducted a field study during Kharif 2023 to study the effect of row spacing on growth and yield of sunflower. The experiment was administered in a randomized complete block design with three replications. Sunflower was grown providing five different row spacings, viz. 25, 30 (recommended), 35 cm, 40, and 45-cm. The crop was raised following standard recommended agronomic practices and balanced fertilization. Our findings suggested that narrow row spacing (25 cm) significantly enhanced the vegetative traits of sunflowers, i.e., plant population and plant height. In contrast, wide row spacing found significantly beneficial in decreasing the days to 50% flowering (at 40-cm) and days to 50% maturity (at 45-cm). Interestingly, wider row spacing (45-cm followed by 35-cm) significantly enhanced stem girth, head diameter, achene per head, achene weight per head, 1000-achene weight, achene yield, and oil content of sunflower. It was evident that the improved yield traits of sunflower, especially achene characteristics, enhanced the achene yield and oil content of sunflower. In contrast, all these traits were found to be lowest where sunflower was planted in rows that were 25-cm apart. We conclude that sowing of sunflower with a wide row spacing of 45-cm, as against comparatively narrow row spacings, significantly improves its yield contributing traits, achene yield, and oil content.

Published: January 2025

Utilizing Gaia data from the literature, we report a new young (∼8.9 Myr) cluster pair, ASCC 19 and ASCC 21, located near the Orion star-forming complex. The clusters are separated by a 3D distance of 27.00 ± 7.51 pc. Both clusters share a common age (Log(age) = 6.95 ± 0.05), similar radial velocities (RV = 21.34 ± 4.47 km s−1 for ASCC 19 and RV = 20.05 ± 3.86 km s−1 for ASCC 21), and comparable metallicities ([Fe/H] = −0.14 ± 0.25 dex for ASCC 19 and [Fe/H] = −0.12 ± 0.04 dex for ASCC 21, from LAMOST-DR11). These similarities suggest that the clusters likely originated from the fragmentation of the same molecular cloud, forming a primordial cluster pair. Furthermore, the formation of the two clusters is attributed to the coalescence of multiple subclusters, as inferred from the distribution analysis between metal abundances and distances to clusters’ centers. Neither cluster shows significant mass segregation. Their members with RVs exceeding 100 km s−1 are young variables. Additionally, a tidal interaction between the clusters is observed. Comparisons of the Roche radius with tidal radii, as well as velocity difference with orbital velocity, suggest that the pair is an unbound system, that is, a double cluster. Finally, orbital motion simulations show that the clusters will not merge into a single system.

Analyse transactionnelle et psychothérapie relationnelle : nous avons besoin d’un intérêt renouvelé et de réflexion contemporaine
Authors: Brevière Rachel , McLean Brad , Treharne Muriel
Published: January 2025

L’auteur passe en revue tous les articles sur la psychothérapie et le conseil relationnel et conjugal, publiés dans le Transactional Analysis Journal (TAJ) entre 1970 et 2021, afin de voir si l’analyse transactionnelle dispose d’un modèle solide de psychothérapie relationnelle. Il tire une analyse synthétique de leur contenu à la recherche d’une approche cohérente, intégrée et systématique de cette pratique et tente de déterminer si celle-ci est éclairée par la théorie et la pratique contemporaines. Depuis les années 1970, le nombre d’articles sur la psychothérapie des relations publiés dans le TAJ d’articles a fortement diminué, alors même que le champ plus large de la psychothérapie relationnelle s’est étoffé. La discussion se penche sur le travail important qui apparaît nécessaire pour développer ce domaine de la pratique.
L’organisation de l’espace et du temps au Quartier Mu de Malia (Crète, âge du Bronze, 3200 – 1100 av. J.-C.), à la lumière des lampes
Authors: Rueff Bastien
Published: January 2025

Le développement de la réalité virtuelle a permis, ces dernières décennies, de proposer des reconstitutions réalistes d’éclairage dans les édifices de l’âge du Bronze en Méditerranée orientale et dans le bassin égéen. Lumière et obscurité ont toutefois été étudiées séparément, l’une pour la vie quotidienne en journée, l’autre pour les activités nocturnes, les rituels et les croyances. En étudiant une agglomération crétoise du Bronze Moyen et son corpus de lampes, il est possible d’identifier plusieurs dispositifs d’éclairage de natures et de fonctionnalités différentes dont l’analyse contribue à révéler un espace vécu minoen où lumière et obscurité ne peuvent être dissociées.
Apprivoiser l’obscurité : un nouveau programme pour l’architecture des salles de cinéma parisiennes entre 1914 et 1921
Authors: Thouron Mathilde
Published: January 2025

La révolution industrielle et ses avancées techniques de l’époque contemporaine favorisèrent dès le 19e s. une incorporation massive du verre dans les constructions architecturales, ce qui permit la transparence des volumes et l’entrée de la lumière naturelle dans l’environnement bâti. En parallèle, la « fée électricité » généra un type nouveau d’obscurité. La science et les champs artistiques liés à la scène exploitèrent ces différentes qualités du sombre au sein de dispositifs agissant aussi bien sur la représentation que sur le statut de l’observateur. Ainsi, tandis que l’heure était à l’ouverture des bâtiments sur l’extérieur, les architectures se virent obligées d’adopter aussi la composante obscure afin d’intégrer une variété de machines de projections. Amenée par un renouvellement énergétique, l’obscurité se vit investie dans la production d’architectures dédiées à la projection cinématographique.

Introduction:

Chronic hypertension is a serious physiological condition that develops histopathological abnormalities such as remodelling, hypertrophy in heart muscle and vasoconstriction of blood vessels. The aim of the study was to determine the impact of almond, walnut and corn oils on remodelling and hypertrophy of the heart, aorta and testicles in high blood pressure (BP)-bearing rats.

Materials and Methods:

Twenty-five adult male albino rats (Rattus norvegicus) weighing 200–250 g were used. Rats were divided into 5 groups, with 5 rats in each group, as the following: Group first: normal control: standard rat chow and tap water ad libitum; Group 2: hypertension induced by L-NAME (model): This group received L-NAME (40 mg/kg/day) orally; Group 3: model + walnut oil, received almond oil (3 ml/kg) for 3 weeks; Group 4: model + almond oil, received walnut oil (3 ml/kg) for 3 weeks and Group 5: mode + corn oil, received corn oil (3 ml/kg) for 3 weeks. The experiment took 28 days, BP was recorded each week and then the animals were sacrificed under the effects of ketamin-xylazine anaesthesia by cervical dislocation. Histopathological slices were taken from the whole heart, aorta and testes using the standard method. The mean BP for each group was presented in the table, and t-test was used for statistical analysis. Histopathological results for each group are shown in the figures.

Results:

In contrast to almond oil, walnut oil and corn oil have significantly reduced BP (157.9 ± 4.490 mmHg) to (140.1 ± 3.068 mmHg) but not to the control level (130.7 ± 2.605). Walnut and corn oil could prevent tunica media thickness in the aortic, remodelling and hypertrophy in cardiac muscle and protect the architecture of spermatogenesis tissue in seminiferous tubules of testicle. Almond-treated groups showed no improvement in histopathological changes when compared with the model in aorta, cardiac muscle and testicle.

Conclusion:

Unlike almond oil, corn and walnut oil can reduce high BP induced by L-NAME and alleviate the histopathological changes that occur as the result of hypertension, such as aortic wall thickness and myocadiac hypertrophy.
Role of ultrasound-guided brachiocephalic venous cannulation for difficult venous cannulation in pediatric patients: A narrative review

Difficult venous access is characterized by non-visible and non-palpable veins; a highly experienced operator is required with the use of technological aids to insert a vascular device. Patients with difficult venous cannulation undergo multiple, painful attempts to gain peripheral venous access. Compared to adults, inserting a central venous cannulation (CVC) is thought to be a more difficult procedure in children, particularly in neonates and young infants. IJV catheterization is perceived as the gold-standard route for CVC but remains difficult for newborn, premature, and critically ill children. Therefore, in recent years, novel ultrasound-guided brachiocephalic venous (BCV) cannulation in neonates has gained popularity. The aim of this narrative review was to assess the success rate. The primary objective of this review was to determine the first-attempt success rate. The secondary objectives were the total number of attempts, cannulation time, overall success rate, and complications. All articles relevant to BCV cannulation were searched in six major databases (PubMed, Embase, Medline, Ovid, PMC, and Google Scholar). A total of 16 records were included in this narrative review. According to Breschan et al., Merchaoui et al., and Vafek et al., the success rate of BCV cannulation in children was 89.1%, 98.4%, and 50%, respectively. Kumar et al., Erroz et al., and Breschan et al. found that the first-attempt success rate was higher in the in-plane left BCV (74%, 73% and 82.9% respectively). Falay et al. and Erroz et al. found a lower complication and infection with BCV cannulation. There is evidence that during CVC placement, US-guided BCV cannulation has a higher first-attempt success rate, requires less cannulation time, and has a lower complication rate in comparison to other approaches.

Normalization flow in the presence of a resonance
Authors: Treschev Dmitry Valerevich
Published: January 2025

Following [18], we develop an approach to the Hamiltonian theory of normal forms based on continuous averaging. We concentrate on the case of normal forms near an elliptic singular point, but unlike [18] we do not assume that frequences of the linearized system are nonresonant. We study analytic properties of the normalization procedure. In particular we show that in the case of a codimension one resonance an analytic Hamiltonian function may be reduced to a normal form up to an exponentially small reminder with explicit estimates of the reminder and the analyticity domain.

The socioecological conditions of Mexican regions are conducive to the spread of vector-borne diseases. Although there are established treatment guidelines for dengue and rickettsiosis, diagnosis is complicated. The objective of this work was to identify epitopes of Rickettsia and dengue virus that could be used in serology screening against vector-borne diseases. For this, epitopes with high histocompatibility complex class II binding efficiency of OmpB protein of Rickettsia rickettsii and NS2B protein of dengue virus were identified in silico through a reverse vaccinology strategy. The selected epitopes were grouped into multipeptide sequences that were synthesized and immobilized in a nitrocellulose membrane to evaluate the reactivity sera from patients previously infected with dengue or Rickettsia. The evaluation of the sequences of the NS2B and OmpB proteins was performed with 60 sera previously diagnosed as positive or negative by the respective gold standard techniques. The dot blot technique was used for the antigenic evaluation of the peptides against these serum samples. Dot blot analysis correctly identified 85% of sera positive for rickettsiosis and 75% of sera positive for dengue. Experimental evidence from multipeptide sequences suggests their potential use in the development of diagnostic tests for dengue and rickettsiosis.

Hydropneumatic Struts (HPS) are widely implemented in automobile, aerospace, and
construction industries, mainly for the purpose of vibration and shock
absorption. The HPS design with integrated gas–oil chamber is relatively more
compact and robust, while mixing gas and oil inside the HPS generates gas–oil
emulsion and more nonlinearities. This study formulated a nonlinear analytical
model of the compact HPS with gas–oil emulsion, considering the real gas law and
pressure-dependent LuGre friction model. The polytropic version of the van der
Waals (vdW) method for real gas is applied to represent the thermodynamic
behavior of nitrogen. The experimental data were collected at a near temperature
of 30°C with three charging pressures under excitations in the frequency range
of 0.5–6 Hz, considering two flow connection configurations between chambers as
one- and two-bleed orifice. The nonlinear behavior of the gas volume fraction of
the emulsion was identified based on peak strut velocity and charge pressure.
Discharge coefficients of bleed and check valves were determined as a function
of the instantaneous pressure difference between chambers. The parameters of the
pressure-dependent LuGre model, such as the stiction force and Coulomb force
apart from stiffness and damping coefficient of bristle deflection, were also
investigated considering the effect of pressure variation. Compared to the
generally used ideal gas and models, the proposed model considerably improved
the prediction accuracy of the total force and pressures of HPS, with normalized
root-mean-square deviations of about 8%.

Current work details the preliminary CFD analysis performed on custom-built race
car by Team Sakthi Racing team as part of Formula SAE competition using
OpenFOAM. The body of the race car is designed in compliance with FSAE
regulations, OpenFOAM utilities and solvers are used to generate volumetric mesh
and perform CFD analysis. Formula student tracks are typically designed with
numerous sharp turns and a few long straights to maintain low speeds for safety.
In order to enhance the cars’ performance in sharp turns, the race car should be
equipped with aerodynamic devices like nose cone and wings on both the rear and
front ends within the confines of the formula student racing rules. Thus,
efficient aerodynamic design is highly critical to maximizing tire grip by
ensuring consistent contact with the track, reducing the risk of skidding, and
maintaining control, especially during high-speed maneuvers. In this work, the
performance and behavior of the race car, both with and without the impacts of
wing installation, are determined by the aerodynamic drag and downward forces as
the flow passes over it. In conclusion, this preliminary analysis highlights the
improved downward force due to the adoption of wings on both front and rear side
of the vehicle.

Magnesium oxide (MgO) nanofluids are of great interest for enhancing the
performance in thermal management especially in automotive applications, where
efforts have been made to reduce parasitic losses from traditional cooling
systems. These findings highlight the effects of Water–ethylene glycol and MgO
nanofluids on viscosity and thermal conductivity in specific filling a gap in
research that allows to clarify how these states behave at different temperature
(T) and concentration (C) conditions. Test results demonstrate that the thermal
conductivity of MgO nanofluids improved adequately /while its corresponding
change in viscosity remained under control, affirming a significant improvement
for energy savings by means heat transfer enhancement using new generation
coolants based on this nano-additive. The results also provide useful
information for design and development of automotive cooling systems, including
real numbers on performance improvements that lead to more efficient and
reliable thermal management designs.
