Lessons from High-Speed Data Acquisition on Frac Plug Milling Operations
Authors: Newman Ken , Kelleher Patrick 
Published: March 2023

Abstract
Previous work has shown that large force waves traveling through the coiled tubing (CT) correlated with extended reach tool (ERT) operations can generate axial vibration harmonics in the CT that may lead to CT failures. This paper documents continued work which has shown that the surface equipment also has natural frequencies of vibration. When these natural frequencies are multiples of the ERT frequency, the ERT stimulates the surface equipment vibration modes.

Abstract

Stone fine powder (SFP) is a solid by-product of the stone-cutting industry, which causes land and air pollution in the surrounding areas. In this study, SFP was used as a raw material in the manufacturing of lightweight material of SFP-based rice husk concrete blocks (RHCBs), and its optimal content to meet the performance of Indonesian standards was determined. The RHCBs studied here were composed of three materials: cement (binder), SFP, and raw rice husk (RRH). Samples were grouped into three batches: Batch-I, Batch-II, and Batch-III with binder-RRH ratios of 1:2, 1:3, and 1:4 respectively. Moreover, six binder-SFP ratios were tested in each batch, i.e., 1:0.25, 1:0.50 1:0.75, 1:1, 1:1.25, and 1:1.50. Thus, 18 mixes were cast to assess the performance of the SFP-based RHCBs. The results revealed that the increase of the SFP content in concrete mixture significantly enhances the density and compressive strength of SFP-based RHCBs, due to their denser structure. The SiO2 as the majority component of SFP does not have an impact on improving RHCB strength because it is chemically inactive. SFP-based RHCB with 300% RRH and the ratio of SFP to binder = 92.82–105.49% is the optimal choice. For practical purposes, it can be regarded as 100% SFP. This synergetic application of binder:SFP:RRH = 1:1:3 in a concrete mixture will generate the best SFP-based RHCB, with a density of around 1,345.22 kg/m3 and a compressive strength of approximately 2.80 MPa.
Global hydrological parameter estimates to local applications: Influence of forcing and catchment properties
Authors: Schalla Jasper , Hartmann Andreas , Abraham Tesfalem , Liu Yan 
Published: March 2023

AbstractData scarcity in many areas around the world represents a major problem for hydrological model calibrations. Global parameter estimates and global forcing can provide possibilities to access hydrological responses in ungauged regions. In this study, we applied HBV global parameter estimates considering uncertainty in the Upper Neckar and Upper Danube catchments, Germany, to answer what are the influencing factors and how good are their local applications. We tested simulations with precipitation in spatial resolutions from 0.05 to 0.2° and with local/global sources. Results show that the general performance is acceptable to good (Kling-Gupta efficiency, KGE: 0.51–0.79) in both catchments using local or global precipitation. The influence of spatial resolutions is insignificant while using local precipitation slightly increases performance in both catchments. Catchment properties such as complex topography and special karst subsurface may lead to a deterioration of performance by 0.2 of median KGE in the Upper Danube compared with the Upper Neckar catchment. The median correlation coefficient, runoff ratio and relative error suggest that using global parameter estimates can reproduce seasonality and long-term water balance in our studied region. Our study highlights the potential of using global parameter estimates and global forcing in ungauged areas.

Objectives: This clinical research aimed to establish autologous fibroblasts transplantation as a possible treatment for patients with DEJ. The COL7A1 gene expression was also evaluated.
Methods: Six patients (3M and 3F), 4 with no recurrent wounds and 2 with recurrent wounds after surgery, and 15 healthy subjects were included in the study as controls. Quantitative real-time polymerase chain reaction (real-time PCR) analysis of the COL7A1 gene was performed using an oligonucleotide primer pair designed to amplify across the exon/exon junction.
Results: The COL7A1 expression level was down-regulated at exons 26-27, 47-48, 96-97, and 116-117 in all patients′ fibroblasts compared with the healthy controls. However, the expression of the COL7A1 gene in the fibroblasts of the patients with a positive response to the treatment was not significantly changed compared with the patients with the poor response. (ClinicalTrials.gov NCT01908088)
Conclusion: In this study the mRNA expression levels of COL7A1 were significantly less in the patients when compared with healthy controls. However the COL7A1 expression after autologous fibroblasts transplantation was not different between the two groups of patients, and further examination is needed to elucidate the mechanism of the treatment.

Published: March 2023

Abstract
Biopolymer carboxymethyl tamarind seed kernel polysaccharide (CMTSP) was synthesized by the reaction of tamarind kernel powder (TKP) of Tamarindus indica L. with monochloroacetic acid by an improved method. The synthesis was conducted in presence of sodium hydroxide at optimized conditions of time, temperature, concentrations of TKP, MA, sodium hydroxide. Tamarind seed polysaccharide (TSP) was also extracted from TKP by boiling distilled water. The chemical structure of TKP, TSP and CMTSP were analyzed by the ATRFTIR. When TKP, TSP, and CMTSP’s comparative physico-mechanical properties were examined and compared, CMTSP performed better due to increase in viscosity, water solubility and tensile properties.
Phenomenological Model of Cavitation Erosion of Nitrogen ION Implanted Hiped Stellite 6
Authors: Szala Mirosław 
Published: March 2023

Abstract
Stellites are a group of Co-Cr-C-W/Mo-containing alloys showing outstanding behavior under cavitation erosion (CE) operational conditions. The process of ion implantation can improve the CE resistance of metal alloys. This work presents the elaborated original phenomenological model of CE of nitrogen ion implanted HIP-consolidated (Hot Isostatically Pressed) cobalt alloy grade Stellite 6. The ultrasonic vibratory test rig was used for CE testing. The nitrogen ion implantation with 120 keV and fluence of 5 × 1016 N+/cm−2 improves HIPed Stellite 6 cavitation erosion resistance two times. Ion-implanted HIPed Stellite 6 has more than ten times higher CE resistance than the reference AISI 304 stainless steel sample. Comparative analysis of AFM, SEM and XRD results done at different test intervals reveals the kinetic of CE process. The model includes the surface roughness development and clarifies the meaning of cobalt-based matrix phase transformations under the nitrogen ion implantation and cavitation loads. Ion implantation modifies the cavitation erosion mechanisms of HIPed Stellite 6. The CE of unimplanted alloy starts on material loss initiated at the carbides/matrix interfaces. Deterioration starts with cobalt matrix plastic deformation, weakening the carbides restraint in the metallic matrix. Then, the cobalt-based matrix and further hard carbides are removed. Finally, a deformed cobalt matrix undergoes cracking, accelerating material removal and formation of pits and craters’ growth. The nitrogen ion implantation facilitates ɛ (hcp—hexagonal close-packed)) → γ (fcc—face-centered cubic) phase transformation, which further is reversed due to cavitation loads, i.e., CE induces the γ → ɛ martensitic phase transformation of the cobalt-based matrix. This phenomenon successfully limits carbide removal by consuming the cavitation loads for martensitic transformation at the initial stages of erosion. The CE incubation stage for ion implanted HIPed Stellite 6 lasts longer than for unimplanted due to the higher initial content of γ phase. Moreover, this phase slows the erosion rate by restraining carbides in cobalt-based matrix, facilitating strain-induced martensitic transformation and preventing the surface from severe material loss.

Published: March 2023

Abstract
This paper presents a parallel approach to the Levenberg-Marquardt algorithm (LM). The use of the Levenberg-Marquardt algorithm to train neural networks is associated with significant computational complexity, and thus computation time. As a result, when the neural network has a big number of weights, the algorithm becomes practically ineffective. This article presents a new parallel approach to the computations in Levenberg-Marquardt neural network learning algorithm. The proposed solution is based on vector instructions to effectively reduce the high computational time of this algorithm. The new approach was tested on several examples involving the problems of classification and function approximation, and next it was compared with a classical computational method. The article presents in detail the idea of parallel neural network computations and shows the obtained acceleration for different problems.
Using Cognitive Models to Understand and Counteract the Effect of Self-Induced Bias on Recommendation Algorithms
Authors: Pawłowska Justyna , Rydzewska Klara , Wierzbicki Adam 
Published: March 2023

Abstract
Recommendation algorithms trained on a training set containing sub-optimal decisions may increase the likelihood of making more bad decisions in the future. We call this harmful effect self-induced bias, to emphasize that the bias is driven directly by the user’s past choices. In order to better understand the nature of self-induced bias of recommendation algorithms that are used by older adults with cognitive limitations, we have used agent-based simulation. Based on state-of-the-art results in psychology of aging and cognitive science, as well as our own empirical results, we have developed a cognitive model of an e-commerce client that incorporates cognitive decision-making abilities. We have evaluated the magnitude of self-induced bias by comparing results achieved by simulated agents with and without cognitive limitations due to age. We have also proposed new recommendation algorithms designed to counteract self-induced bias. The algorithms take into account user preferences and cognitive abilities relevant to decision making. To evaluate the algorithms, we have introduced 3 benchmarks: a simple product filtering method and two types of widely used recommendation algorithms: Content-Based and Collaborative filtering. Results indicate that the new algorithms outperform benchmarks both in terms of increasing the utility of simulated agents (both old and young), and in reducing self-induced bias.
Configurational Models to Predict Hosting Sporting Events: The Perceptions of Urban Residents

Published: March 2023

Abstract
The purpose of this paper is to obtain the combination of conditions that lead to high levels of residents’ support for the hosting of sports events. In addition, we aim to identify which of these combinations can lead to low levels of support for hosting these events. a validated survey was administered to 342 residents. An asymmetric approach (Qualitative Comparative Analysis) was used to examine these variables and calculate the combination of conditions that lead to these two outcomes. To achieve high levels of residents’ support for the hosting of sports events, a combination of residents’ perceptions of psychosocial, sporting and socio-cultural impacts, and the absence of socio-cultural costs, is the main solution. However, support is low if residents perceive that holding the event has no positive psychosocial impacts, but only socio-cultural costs for the local population. This study provides information on achieving residents’ support for the organization of sports events. Local authorities should focus their efforts on reinforcing local traditional values, thus allowing for increased local pride, as well as creating a festive atmosphere during the celebration of the event. It is also necessary to carry out campaigns to promote sports, avoiding a cultural clash between visitors and residents.
The Central and Eastern European Countries: A Cluster Analysis from a Bioeconomy Perspective
Authors: Bălan Emilia Mary , Cismas Laura Mariana 
Published: March 2023

Abstract
The bioeconomy is an area that encompasses more economic activities and is environmentally friendly and sustainable. Bioeconomy contributes to the economic development of a state by creating new jobs, expanding the business environment and making activities more efficient. In this context, the bioeconomy is an element of economic development that helps the Central and Eastern European countries (CEECs) to bridge the gap with the other countries in the west of the continent. The article aims to analyze the grouping of CEECs based on indicators specific to the bioeconomy, to highlight similarities or discrepancies between them. Moreover, we conduct this study in order to identify Romania’s position among CEECs in terms of specific bioeconomy indicators. The study is based on the European Commission’s Joint Research Center database for the bioeconomy indexes for these particular regions. We employed a hierarchical cluster method using SPSS software. The sample consisted of the 11 CEEC Member States (MS) of the European Union (EU), and the period under review was between 2008 and 2019. The research indicators included turnover, number of workers, apparent labour productivity, and added value. The results show that Slovakia, Croatia and Romania form individual groups at an iteration level between 0 and 15, indicating significant discrepancies between countries in the region. The novelty of the research derives from the fact that there are no previous analyses that compare Romania’s status with other CEECs from the perspective of bioeconomy. Therefore, the paper can contribute to the implementation by the Romanian authorities of a set of measures necessary to develop the strategy dedicated to the bioeconomy based on good practices from the other CEECs.
Labour Market Challenges: Will There Be “Dystopian” Risks?
Authors: Cismas Laura Mariana , Dumitru Cornelia , Negrut Teodor 
Published: March 2023

Abstract
The current labour market is at a crossroads: on one hand, there are challenges triggered by technological pressures and perks, aiming at a greener, more sustainable and resilient economic growth, and on the other hand, there are the changes and tensions generated by the current institutional frameworks, that show delays in mitigating the apparent “de-socialising” of this market. The pandemic paradox of 2019-2021 has emphasized several vulnerabilities particularly of economic-institutional nature. Traditional theories seem unsatisfactory while unorthodox approaches are faced with hesitancy. The present paper intends to present a brief analysis of labour market’s challenges in the immediate future by proposing a mixed approach combining traditional statistical-data with a less employed institutional framework. The approach is substantiated and constructed by the structural and cognitive features that the new labour market would require. It suggests a possible way for considering the aims of the Green Deal, the vulnerabilities highlighted by the pandemic and by the recent conflict in the immediate proximity of the EU-27. All these developments bring about changes for several socio-economic categories, rendering most of them vulnerable. The split between “essential” and “non-essential” economic activities, platform work and the gig economy hint to increased relevance of the three types of intangible capital: human, social and intellectual. This will require an integrating perspective, if severe economic and social effects are to be avoided in the immediate future. The model we propose aims to show how, by taking account of the human, social and intellectual capital, better policies can be developed as regards labour market efficiency and efficacy.
