Electrical and thermal modeling of battery cell grouping for analyzing battery pack efficiency and temperature
Authors: Rahman Md. Ashifur , Baki Abul Kalam Muhammed 
Published: August 2023

Abstract
Efficiency of the battery pack largely depends on the resistive losses and heat generation between the interconnections of the battery cells. Grouping of battery cells usually is done in different ways in industries. However, losses vary depending on applications or states of electric vehicle (EV). Therefore, it is necessary to determine the efficiency and heat generation in battery cells as well as battery packs. In practical situations, some battery cells are charged rapidly in comparison to other battery cells. On the other hand, when an EV is in running condition some battery cells are discharged rapidly. As a results battery pack cannot provide better efficiency and its life span is reduced. As an alternative option the inter-cell connection of battery package is needed to reconfigure in an optimized way. In this paper firstly, a battery pack with switches is modeled and then efficiency and temperature variation with respect to time are determined. Then, an experimental setup is investigated to measure the efficiency and temperature rise with respect to time. Results, explained in the paper, demonstrate that battery pack with switches increases the efficiency if it is measured after switching (97–98 %), while temperature increases from 25 °C to 50 °C for different C-rates.

Abstract
Electric energy is the most commonly used energy in people’s daily life. In the process of use, how to improve the utilization rate of resources, so as to achieve the purpose of energy saving and environmental protection of power resources is a very significant work. The power grid is crucial in the transmission of electricity, and the energy consumption of substations is a major factor affecting the operation cost. Therefore, it is a key condition to ensure the stable operation of the power grid to scientifically calculate its energy consumption and formulate appropriate energy-saving measures. After consulting a large number of relevant documents and data, it has been found that many researchers have provided new ideas for the calculation of energy consumption and the study of energy-saving measures in substations. This article was adding its own understanding and taking it as the direction and basis. In the introduction, the research significance of substation energy consumption calculation was introduced, and then the academic research and analysis were carried out on the two key sentences of substation energy consumption calculation and analysis and the research of multi-objective artificial bee colony (ABC) algorithm in substation. In the method part, a constructive algorithm theory was proposed, and the application of the algorithm in substation energy consumption was proposed to provide a theoretical basis for the energy consumption calculation and energy conservation measures research of substations based on multi-objective ABC algorithm. At the end of the article, a simulation comparison experiment was carried out and the experiment was summarized and discussed. Firstly, the performance of the two algorithms was analyzed. Then, through the first selection of power plant T and Y, it was concluded that the resistivity of the cable in the distribution room in power plant Y was much higher than the average value based on the experimental results. Therefore, it was taken as the sample subject of the following experiments and analyzed again. For the second time, the analysis of district power plant Y showed that through simple calculation, the average energy efficiency difference of the distribution room before and after use was 3.1. Finally, it was analyzed that the ABC algorithm could not only improve the energy efficiency of the distribution room in the power plant, but also improve the effective efficiency of its power station. It shows that this kind of algorithm is effective and worthy of further study.

Abstract

Context
Fluoroscopic injection through the rotator cuff interval (RCI) is a common technique for diagnostic arthrography and therapeutic intervention. Ultrasound approaches through the RCI have been less commonly studied, but there is a growing body of literature.

Objectives
The purpose of this study was to present a standardized technique of ultrasound-guided injection into the glenohumeral joint utilizing the RCI in magnetic resonance imaging (MRI) arthrography (MRA) and to report one medical group’s experience with the technique.

Methods
A retrospective chart review of all ultrasound-guided injections into the glenohumeral joint utilizing the RCI was performed from July 1, 2014 through June 1, 2021. Data were compiled for age, gender, body mass index (BMI), and prior surgery on the shoulder. The primary endpoint was successful administration of intra-articular dilute gadolinium contrast adequate for radiologic interpretation. A total of 487 injections into the glenohumeral joint via the RCI were performed. One hundred and fifty-five patients had previous shoulder surgery, with the remainder naive to intervention.

Results
The success rate of injections into the glenohumeral joint was 99.4 %, with only three injections considered unsuccessful. The three unsuccessful injections did not succeed because of a lack of intra-articular contrast media present. This success rate is impressive and promising, particularly when considering that 155 of the patients had previous surgery, which could potentially cause complications, and because these injections were performed over a long period of 7 years.

Conclusions
Accessing the RCI under ultrasound guidance is a very successful technique for injection within the glenohumeral joint.

Authors: Wang Chao , Zhang Xiaoming , Xiong Chao 
Published: August 2023

Abstract
Small Modular Reactors (SMR) have attracted more and more attention. It can provide economic, stable and clean power for remote areas. It is also a reliable solution in satisfying the power supply of small and medium grids, as well as comprehensive energy supply including heat, electricity, water and steam, and distributed energy supply. Internal Fire Probabilistic Risk Assessment (PRA) is a system analysis method of assessing fire risk for a nuclear power plant, which plays a more and more important role. It can provide an overall understanding of the internal fire risk for SMR. Corresponding design optimization suggestions can be obtained through further analysis of the fire areas with major fire risk, which can help reduce the risk of internal fire and improve the safety of reactor. The paper introduces the basic information of marine SMR and development of internal fire PRA. Then the internal fire risk for marine SMR have been analyzed by this method. The results show that marine SMR have high safety with a Core Damage Frequency (CDF) for internal fire risk of less than 1.0 × 10−7 per year.

Published: August 2023

AbstractRapid saccadic eye movements are used by animals to sample different parts of the visual scene. Previous work has investigated neural correlates of these saccades in visual cortical areas such as V1; however, how saccade-responsive neurons are distributed across visual areas, cell types, and cortical layers has remained unknown. Through analyzing 818 1 h experimental sessions from the Allen Brain Observatory, we present a large-scale analysis of saccadic behaviors in head-fixed mice and their neural correlates. We find that saccade-responsive neurons are present across visual cortex, but their distribution varies considerably by transgenically defined cell type, cortical area, and cortical layer. We also find that saccade-responsive neurons do not exhibit distinct visual response properties from the broader neural population, suggesting that the saccadic responses of these neurons are likely not predominantly visually driven. These results provide insight into the roles played by different cell types within a broader, distributed network of sensory and motor interactions.

Published: August 2023

ABSTRACT
Two sets of predictive models are developed based on the machine learning (ML) and general orthogonal regression (GOR) approaches for predicting the seismic source parameters including rupture width, rupture length, rupture area, and two slip parameters (i.e., the average and maximum slips of rupture surface). The predictive models are developed based on a compiled catalog consisting of 1190 sets of estimated source parameters. First, the Light Gradient Boosting Machine (LightGBM), which is a gradient boosting framework that uses tree-based learning algorithms, is utilized to develop the ML-based predictive models by employing five predictor variables consisting of moment magnitude (Mw), hypocenter depth, dip angle, fault-type, and subduction indicators. It is found that the developed ML-based models exhibit good performance in terms of predictive efficiency and generalization. Second, multiple source-scaling models are developed for predicting the source parameters based on the GOR approach, in which each functional form has one predictor variable only, that is, Mw. The performance of the GOR-based models is compared with existing source-scaling relationships. Both sets of the models developed are applicable in estimating the five source parameters in earthquake engineering-related applications.

Authors: Ugarte Carmelino Ameth , Loaiza Porcel Alexandra 
Published: August 2023

El uso de contratos estandarizados en la implementación de proyectos de infraestructura pública ha marcado un hito en las políticas de inversión en infraestructura en el Perú. Desde el año 2019, han sido los contratos New Engineering Contract (NEC) los que han tenido un uso relevante en proyectos de construcción en los que una de las partes contractuales es el Estado peruano. A partir de ello, surge la necesidad de estudiar la gestión del riesgo de financiamiento y su regulación específica en este tipo de contratos. Dada la trascendencia de una correcta gestión del riesgo de financiamiento en un contrato NEC, en el presente artículo se analizarán los deberes y obligaciones relacionadas, así como el origen y las consecuencias del conocido ‘‘desfinanciamiento’’ o ‘‘desequilibrio económico financiero’’ de un proyecto de construcción.

Authors: Ranade Ashish S. , Gandhi Shreyans 
Published: August 2023

Case:
A 9-year-old boy presented with a painful, swollen knee. He had a wound on the knee 2 months ago after a fall in contaminated water. At another hospital, this was treated with debridement twice, and the patient received several antibiotics. Imaging showed septic arthritis and epiphyseal osteomyelitis involving the proximal medial tibia. Surgical debridement and joint washout were performed. Fungal cultures grew Scedosporium boydii. Antifungal treatment with voriconazole was given. At a 5-year follow-up, we noticed favorable outcomes without any complications.

Conclusions:
Fungal osteomyelitis because of direct inoculation should be considered a rare differential diagnosis while treating epiphyseal osteomyelitis.
Triceps Rupture After Olecranon Fixation with Proximal Ulna Plate and Suture Augmentation
Authors: Flores Sergio Eduardo , Sheridan Joseph Ryan , Larson Eric Stanley , Immerman Igor 
Published: August 2023

Case:
Olecranon fractures treated with proximal ulna plate fixation and repairing the triceps with suture augmentation to the plate decrease the risk of “olecranon escape,” but may lead to failure through triceps rupture. In this case report, a rare complication of triceps rupture occurred, and the patient underwent triceps repair.

Conclusion:
When fixing olecranon fractures, surgeons should minimize triceps dissection for hardware placement. If subjected to significant force, a surgical insult to the tendon footprint for a better plate contact on the bone and the presence of suture augmentation may change the construct failure mechanism and result in triceps rupture as opposed to fracture redisplacement.

Published: August 2023

Case:
A 49-year-old woman presented with low back pain after a work-related injury. She failed 5 months of conservative management and subsequently underwent minimally invasive (MI) left sacroiliac joint (SIJ) fusion with 3 triangular titanium implants. Four months postoperatively, she developed recurrence of symptoms and radiographic halo phenomenon about the implants. The cephalad and caudal implants were replaced with threaded self-tapping implants, and the middle implant was unable to be removed. At 7-year follow-up, the halo phenomenon had resolved.

Conclusion:
This is an unusual case of radiographic halo phenomenon formation after MI SIJ fusion and halo resolution after subsequent revision.

Published: August 2023

Case:
A 67-year-old patient sustained a medial clavicle fracture (MCF) treated with open reduction and fixation with cerclage sutures. A year later, he presented with symptomatic nonunion and skin prominence, which was revised with an intramedullary tendon allograft fixation including the sternoclavicular joint. At 31 months after the procedure, the patient showed no pain or clinical instability.

Conclusion:
MCF is an uncommon injury. Symptomatic nonunion after the failure of fixation is rarely described. Although the best way to treat this complication is debatable, revision fixation using an intramedullary tendon allograft can be a viable option in elderly patients.

Summary
Maintaining or increasing production from wells in mature oil reservoirs with high pressure, temperature, brine hardness, and salinity is a significant technological and economic challenge. These wells usually produce with a high gas-oil ratio and large water cuts and often operate with gas lift systems.
This work focuses on the development and application of new multifunctional foaming agents (MFAs) to enhance production from oil wells under these conditions. The MFAs were developed based on molecular design and laboratory studies, which demonstrated that they can be used with water cuts exceeding 30% and in the presence of salinity and hardness levels up to 400,000 ppm and 180,000 ppm, respectively. Furthermore, these agents remain stable at temperatures up to 180°C.
The production/lift efficiency of the MFAs was evaluated using two novel dynamic laboratory methods that are conducted close to the wellhead and at downhole conditions of temperature and pressure, respectively. The experimental results demonstrate a significant enhancement in the liquid production efficiency, with some cases showing an increase from no production to as much as 44% when the MFAs were used.
The laboratory tests were also used to optimize the MFA type and concentration in the design of a field application. The field test was conducted in three oil wells with water cuts ranging from 40% to 90%, depths exceeding 5000 m, bottomhole temperature around 150°C, and brine hardness and salinity up to 180,000 ppm and 310,000 ppm, respectively. This is the first reported field test of MFAs for production enhancement under such challenging conditions.
The MFA was coinjected with gas lift via the annulus. The MFA mixed with reservoir fluids in the tubing and generated foam downhole with concentrations ranging from 160 ppm to 750 ppm. The rheological properties of the foam were designed to prevent pressure losses and the formation of stable foam or emulsions at surface facilities. The field tests demonstrated that the MFA was able to increase oil production at a fixed gas lift injection flow rate. Alternatively, it was able to reduce lift gas consumption while maintaining or even increasing the original oil production.

Abstract
Geological sensitive areas can be mapped using geological terrain mapping approach because this approach is on site combination of geological and terrain features. The objective of this geological terrain mapping in the Ranau area is to provide systematic geological input for landuse planning through the production of various thematic maps to assist in the planning for the future and for the use as a guideline in the approval of construction projects in the Ranau area as well as would assist local authorities, town planners, architects, engineers and stakeholders to control development to ensure the safety of property and public lives. Ranau is located in the highlands central part of Sabah where seismic activities and geohazard phenomena is active due to its complex geological setting. Past tectonic activity causing the occurrences of complex geological setting and active faults movement in the Ranau region. Some of these faults are active and capable to produce seismic activity at any time. The area traversed by the fault zone is prone to instability particularly the threat of geohazard such as landslides, rock falls, debris flow, soil creep and soil settlement. Due to geohazard threat, thus development planning in the Ranau area should be controlled and managed so that areas that tthat underlain by geologically sensitive can be avoided from being developed. The results of geological terrain mapping in Ranau area showed that 32% had low to moderate geotechnical constraints while 68% had high to very high geotechnical constraints.

Abstract
To determine the true causes of earth tremors, high resolution maps created from aircraft radiometric datasets were utilized to illustrate the primary lithology and structural features found in the north-central Nigeria. A range of magnetic amplitudes was seen from the Total Magnetic Intensity. This implies that the underlying rocks are at various depths and have variable magnetic mineral contents depending on the type of rock unit. This is confirmed by generated concentration maps of percentage Uranium, Thorium (u/th)Uranium Potassium (u/k) and Thorium Potassium (th/k) these maps showed low to moderate and high concentration of radio-element. Thorium (0 < 6.4ppm to > 31.9ppm), potassium (0% to > 4.1%), uranium (1.14ppm to < 0.76ppm%). respectively in rocks covering the study area. These results revealed that the study area is geologically characterized by granite gneiss, porphyritic granite rock, felsic granitic rock, schist and migmatite gneiss. Thus, these observed changes in the Total Magnetic Intensity (TMI) map with a low to moderate concentration of the radio elements-identified suggest weathering and intense metamorphism, which could be regarded as unstable, allowing for transmission of seismic energy leading to tremor activities in the study area.
