<p>The no-insulation (NI) high temperature superconductor (HTS) winding technique enables the fabrication of highly compact magnets with self-quench protection. NI pancake coils are implemented to develop a 28 T HTS magnet for the operation of a 792 GHz gyrotron, which is a microwave source for dynamic nuclear polarization nuclear magnetic resonance. To this end, three NI all-GdBCO double pancake (DP) magnets were fabricated using different winding diameters and procedures. The objective was to explore different mechanical coil protection mechanisms at high magnetic fields, including clamping, overband, and solder impregnation. Experiments in liquid helium using magnets with winding diameters of 18 mm, 25 mm, and 66 mm yielded a center field of 14.4 T, 11.2 T, and 8.1 T, respectively. The maximum currents applied to the DP magnets ranged from 780 A to 1000 A. Both the 18 mm and 66 mm DP coils contained 400 m (2 × 200 m) HTS tape, while the 25 mm seamless DP coil consisted of only one continuous 200 m HTS tape. The 25 mm magnet with solder impregnation showed the best repeatability, although the current density was reduced owing to the solder thickness between the coil windings. Critical to the implementation of such coils in liquid helium is to effectively transfer high currents to the magnet, while not compromising the helium boil-off. Furthermore, the design of hybrid copper-HTS current leads capable of carrying current larger than 1000 A from room temperature to the HTS magnet at 4.2 K is presented. The implementation of liquid nitrogen-cooled hybrid copper-HTS current leads reduced the helium boil-off and permitted independent temperature control of the current leads. </p>

Summary. Introduction. Abdominal sepsis (AS) is the most serious complication of inflammatory processes in the abdominal cavity, characterized by high mortality and morbidity. Violation of hemostasis is one of the key components of the pathogenesis of sepsis.
Goal. Establishing the pattern of violations in the system of thrombocyte-vascular hemostasis in patients with abdominal sepsis in the postoperative period, as a prerequisite for the occurrence of adhesions.
Materials and methods. The study covers observation of 52 patients with various forms of AS, aged 18-69 years (41.93±3.47). The control group consisted of 17 patients who underwent planned surgical interventions not related to the peritoneal cavity. The dynamics of the content of soluble fibrin-monomer complexes, prostacyclin and thromboxane were determined by the content of their stable metabolites in the blood.
Results and discussion. Probable correlative dependences between the content of fibrin-monomer complexes in the blood and the concentration of TxB2 (positive correlation) and the level of prostacyclin in the blood plasma (negative relationship) were revealed. Identified violations in the system of primary hemostasis in patients with AS indicate the need for active correction of changes in thromboxane-prostacyclin systems in order to prevent thrombotic postoperative complications of a septic nature.
Conclusions. Identified violations in the system of primary hemostasis in AS already on the first day after surgery indicate the need for active correction of changes in thromboxane-prostacyclin systems in order to prevent thrombotic postoperative complications of a septic nature. Taking into account the high risk of adhesion formation due to inflammatory processes of the peritoneum, it is advisable to consider the identified violations of primary hemostasis as a factor in the pathogenesis of adhesion disease.

Diabetes Mellitus Gestacional (DMG) é uma doença de caráter crônico e progressivo, caracterizada pelas alterações na secreção de insulina, definida como qualquer grau de hiperglicemia. Atualmente, a DMG representa 90% dos casos de gravidez de risco, levando a uma elevada taxa de morbidade e mortalidade fetal. No Sistema Público de Saúde do Brasil, estima-se que 7,6% das gestantes com mais de 20 anos apresentam a doença. O objetivo do presente estudo foi avaliar a incidência de DMG no Hospital Universitário (HU) de Jundiaí-SP, analisando os principais fatores envolvidos no desenvolvimento da doença, bem como as complicações maternas e fetais. A pesquisa foi realizada após aprovação pelo Comitê de Ética Humana da Universidade Paulista UNIP, nº 987.858. Foi aplicado um questionário de 17 perguntas para 40 gestantes, do período de março a abril de 2015. A incidência de DMG foi de 12,5%, sendo os atores de risco apontados: obesidade, síndrome dos ovários policísticos (SOP), histórico de Diabetes Mellitus (DM) tipo I ou II na família e idade avançada. Todas as gestantes entrevistadas realizavam dieta para o controle da doença e apenas uma utilizava medicamento antidiabético oral. Nenhuma das gestantes do estudo apresentou quadro hipertensivo, provavelmente pelo controle alimentar realizado. Os resultados apontam que a incidência de DMG no HU de Jundiaí-SP foi maior que na literatura correlata. O diagnóstico precoce da doença é muito importante para um melhor controle, evitando complicações, como hipertensão. Caso todas as pacientes realizassem um tratamento adequado durante o período gestacional, mantendo a glicemia controlada, não haveria complicações, ou até mesmo a evolução para o DM materno após o parto.

Rapid, green and high yield synthesis of nitrogen doped carbon dots(N-CDs) through exothermic decomposition reaction of H2O2 using grasshopper powder as precursor and polyethyleneimine (PEI) as a surface passivation reagent. Water-soluble fluorescent N-CDs can be obtained by reacting 5 minutes and purified N-CDs were obtained after an activated carbon adsorption separation procedure with a product yield of 53.3%. TEM, FT-IR, XPS, fluorescence and UV-vis spectra were used to investigate the morphology, elemental information and optical properties of N-CDs. The results indicated that the fluorescence emission of N-CDs is typical excitation wavelength dependent with a strongest emission peak at 417 nm under 330 nm excitation wavelength. There is a good linear response between the fluorescence intensity of N-CDs and temperature, which makes N-CDs a potential nanothermometer to monitor temperature. The great spectral overlap between the blue emission peak (417 nm) of N-CDs and the absorption peak (430 nm) of tartrazine (TAR) leads to an effectively fluorescence quenching phenomenon by TAR through inner filter effect (IFE) and the fluorescence quenching degree (lg(I0/I)) was linearly response to the TAR concentration in the range of 1-100 µM. The detection limit of developed method is 54.3 nM for TAR, and the relative standard deviation (RSD) is 1.14% (n=7, c=10 μM). The N-CDs came from an exothermic reaction is a highly selective and sensitive fluorescent probe for TAR, and it was successfully applied to the determination of TAR in food samples with satisfactory results.

<em>Jelai (Coix lacryma jobi L.) that is cultivated in Bulungan Regency has thin and soft skin, yellowish brown in color and slightly shiny surface. The high content of starch and other components in barley increases the potential of Jelai as a food that has functional properties. This study aims to examine the relationship between the structural characteristics, amylograph properties, and digestion of Jelai natural starch (PAJ) and compare it with commercial cassava starch (PS) and corn starch (PJ). The research is started with the isolation process of jelai starch and then structural observations were carried out by SEM test, amylograph properties through RVA test, and digestibility including rapidly digestible starch (RDS), slowly digestible starch (SDS), and resistant starch (RS). PAJ has a low amylose content and a polygonal morphology with a clearly visible central pore / channel. The crystallinity of PAJ is slightly high with A-type crystalline, the same as PJ and PS. The starch structure in PAJ contributed to a slightly lower gelatinization temperature compared to PJ and the lowest setback viscosity compared to PJ and PS which indicated that PAJ was more resistant to retrogradation, as well as the highest RS levels and the lowest RDS compared to PJ and PS. </em>
Taxonomical Modeling and Classification in Space Hardware Failure Reporting
Authors: Palacios Daniel , Hill Terry R. 
Published: July 2023

Abstract
NASA Johnson Space Center has collected more than 54,000 space hardware failure reports. Obtaining engineering processes trends or root cause analysis by manual inspection is impractical. Fortunately, novel data science tools in Machine Learning and Natural Language Processing (NLP) can be utilized to perform text mining and knowledge extraction. In NLP the use of taxonomies (classification trees) are key to the structuring of text data, extracting knowledge and important concepts from documents, and facilitating the identification of correlations and trends within the data set. Usually, these taxonomies and text structures live in the heads of experts in their specific field. However, when an expert is not available, taxonomies and ontologies are not found in data bases, or the field of study is too broad, this approach can enable and provide structure to the text content of a record set. In this paper an automated taxonomical model is presented by the combination of Latent Dirichlet Allocation (LDA) algorithms and Bidirectional Encoder Representations from Transformers (BERT). Additionally, the limitations and outcomes of causal relationship rule mining models, commercial tools, and deep neural networks are also discussed.

Published: July 2023

<p>The practical design of Free-space optical communication (FSOs) faces significant challenges due to atmospheric turbulence and pointing errors. To overcome these obstacles, a hybrid technology combining FSO with NB-PLC scheme has been analyzed in this paper. The study evaluates the area coverage of a hybrid model of Power Line Communication (PLC) and Free Space Optical Communication (FSO) by measuring the Successful Transmission Probability (STP) and probability of error. The analysis assumes that the PLC channel undergoes Rayleigh fading, while FSO links are modeled using the Gamma?Gamma distribution. An algorithm is used to weigh each link by its Successful Transmission Probability (STP) and select the best possible path using the Single Channel Selection scheme (SCS). The Monte Carlo simulation results demonstrate that the pro?posed system is highly advantageous in smart city environments where channel fading is dynamic. </p>

Published: July 2023

Purpose: This paper studies a 3-dimensional pallet loading problem considering interlock stacking pattern, box dimensions, humidity, and storage time, where overlapping and overhanging are not allowed. Despite the importance of this problem in the literature, our work provides the first method that considers the environmental conditions such as 1) storage time and 2) humidity, and their tremendous impacts on the strength of the boxes, as has been observed widely in the DHL supply chain.Design/methodology/approach: This paper proposes a two-phase heuristic algorithm to solve a 3-dimensional pallet loading problem under real conditions (relative humidity, and storage time) considering interlock stacking patterns, where overlapping and overhanging are not allowed. In phase 1, the horizontal layer configuration is determined by block techniques. Three types of horizontal layers are created based on box dimensions perpendicular to the base. In phase 2, a novel mathematical model is propounded to improve the pallet volume utilization, and stability considering the pallet's maximum allowable height and weight, and the dynamic compression strength of boxes. The dynamic compression strength of boxes is calculated by the modified McKee formula. Two performance measures, pallet volume utilization and stability (load height), are utilized to evaluate the performance of the proposed heuristic algorithm in real-world instances (DHL Supply Chain). Findings: The results illustrated that the dynamic compression strength of boxes decreases as the relative humidity and storage time increase. The load height changes dynamically along with box dimensions, box alignment, direction, relative humidity, and storage time. Increasing relative humidity and storage time and applying an interlock stacking pattern reduce the pallet utilization, however, enhance the pallet stability. Finally, the proposed heuristic algorithm's efficacy increases as the identical boxes dimensions' heterogeneity increases.Originality/value: It is believed in the supply chain where these characteristics are observed, the implementation of the heuristic algorithm will help them improve the pallet volume utilization and stability.

La filière litchi est la principale source de conception pour Madagascar, les marchés Européens sont les principales destinations de leur exportation ; les réglementations de l'Union Européenne en matière phytosanitaire et sanitaire ont été élaborées pour l'exportation à l'anhydride sulfureux ; l'exportation de litchis à Madagascar présente 30 % de fruits non conformes aux exigences des marchés européens comme de petits calibres, de couleur jaunâtre ou présentant des fissures et autres ; ils sont alors jetés et réfléchis comme déchets ; la valorisation de ces fruits de litchis est incontournable du fait de ses possibilités d'exploitation ; même si son mûrissement est de deux mois dans l'année, ses transformations apportent une valeur ajoutée à l'exportation ; ce qui a conduit à mener une étude sur la conservation de ces déchets sous forme de fruits dénoyautés et conservés au sirop ; leur exploitation représente une perspective d'avenir non seulement pour les exportateurs du dit fruit mais aussi pour tous les acteurs de la filière et consommateurs, aboutissant ainsi à de nouvelles dispositions du marché extérieur ; C'est une méthode naturelle et durable de conservation.
An Orthogonal Polynomial Based Iterative Procedure for Finding the Root of the Equation f (x) = 0
Authors: Mamadu E. J. 
Published: July 2023

Iterative methods provide hope for many nonlinear engineering problems that cannot be solved through analytic procedures. In this article, orthogonal polynomial based iterative schemes are developed for the approximate solutions of nonlinear algebraic and transcendental equations. Basically, Mamadu-Njoseh orthogonal polynomials are employed as basis functions to derive the new iterative schemes called the “Mamadu \(\Delta\) 2 and \(\Delta\) 3 iterative schemes”. Convergence analysis of the schemes shows the convergence rate as of order 3 and 4, respectively. Numerical experimental of the new schemes show the feasibility and correctness of the method.
