Abstract

The present paper is aimed at studying hydrophilic and hydrophobic interactions via the modeling behavior of carbonate-clayey soil in a laboratory experiment. The typical aspects of human impact on the biogeochemical processes of natural soils such as decompression, disintegration, hydration and introducing easily oxidized organic matter were simulated. The experimental settings were adjusted regarding common field conditions for the clay near-surface layers in the temperate zone. The model system consisted of a carbonate-clayey soil, filtering water, and a psychrophilic microbial community desorbed from cave calcite formations (speleothems). The carbonate-clayey soil was collected from eluvium on red clay bedrock deposits of the Permian system along the right bank of the Volga River in the Republic of Tatarstan. The microbial community was stimulated with a modified R2A growth medium and inoculated into the clay using ceramic carrier discs. In order to explain the results of the experiment auxiliary materials presented simplified systems of the carbonate clay components were used. Soil properties such as the size distribution of mechanically strong particles and microaggregates, mineral composition, organic matter content, water wettability, and the chemical composition of filtered water were determined. The experiment being carried out during six months showed the appearance of new hydrophobic contacts between soil particles, crystalline cement deposition and the high sensitivity of these processes to microbial activity. The results of the study may help in understanding the processes that occur when foundations for constructions or underground facilities contact microbially produced substances, as well as predicting soil weathering.

Abstract
Declining soil fertility limits smallholder macadamia productivity in Malawi. In order to reverse this trend, it is essential to apply organic and inorganic fertilisers in an efficient and effective manner. Yet, fertiliser recommendations for smallholder macadamia (Macadamia integrifolia) production in Malawi are not site-specific. Nutrient imbalances can occur if fertilisers are applied without a clear understanding of whether they are required or not. This may lead to yield losses, unnecessary costs, and other environmental issues associated with excess fertiliser application. To address this knowledge gap, our study examined the current soil fertility status among smallholder macadamia farms in Malawi. Specifically, the objective was to establish an evidence base for promoting soil fertility restoration interventions for smallholder macadamia production. One hundred and eighty nine soil samples at a depth of 0–15 cm were collected from sixty three smallholder macadamia farms belonging to the Highlands Macadamia Cooperative Union Limited members in central and southern Malawi. We found that the majority of the soils were sandy loams (52%), strongly acidic (mean pH ≤ 5.1), and deficient in essential nutrients required for the healthy growth of macadamia. The soils had an average low cation exchange capacity of 1.67 cmol (+) kg− 1, which is inadequate for macadamia cultivation. Over half of the sampled soils had very low organic matter content (≤ 1%). The low soil organic matter content, coupled with the sandy texture and high acidity, contributed to the observed low concentrations of essential nutrients and cation exchange capacity. Poor agronomic practices and the long-term uptake of nutrients by macadamia trees and annual crops are responsible for this low soil fertility. Altogether, our findings underscore the urgent need to identify and implement more sustainable and effective soil nutrient management practices that help to improve the soil fertility of macadamia farms under smallholder systems.
Sourcing Third Party Logistics Service Providers based on Environmental, Social and Corporate Governance: A Case Study
Authors: Moreira Otacilio , Rodrigues Maria Carolina 
Published: January 2023

Abstract
The acronym ESG, environmental, social and governance, emerges as a strong trend in the era of the circular economy and stands out as a need for companies to respond to the segment in which they operate. Although most studies have been done in the past, they did not address ESG criteria to ensure operator exemption for logistics providers. Further research on the application of realistic circular economy techniques is recommended. Therefore, strategic sourcing, based on multicriteria decision analysis (MDA), considering parameters such as economic, technical, and environmental factors, has created a perfect methodology that considers all these essential requirements, revealing an excellent way to outsource logistics service providers (LSPs). The article aims to examine a Brazilian pharmaceutical company during a procurement’s strategic sourcing process through a bibliographic revision supported by a case study. The main objective is to prove the effectiveness of the Multicriteria Decision Analysis tool in awarding the best LSP through predefined dimensions involving human resources, risk management, environmental and other social aspects, indicating dedication and commitment to socioenvironmental issues and corporate governance.

Abstract

Burnout syndrome (BOS) is an affection mostly resulting from chronic job-related stress. Many studies have identified job-related and non- job-related factors associated with BOS. The aim of this study was to assess the level of BOS in private and public hospital healthcare providers in Fako division, Cameroon and evaluate the impact of physical activity and sleep quality (SQ). The study was carried out in five randomly selected hospitals in Fako Division over a three-month period. Consenting doctors, nurses and laboratory technicians were recruited using consecutive sampling method. Sociodemographic and professional characteristics were collected using structured questionnaire. BOS was assessed using the Maslach Burnout Inventory Human Services Survey (MBI-HSS). Sleep quality (SQ) and physical activity (PA) were assessed using Pittsburgh Sleep Quality Index (PSQI) and Global Physical Activity Questionnaire (GPAQ) respectively. Odd ratios and 95% confidence intervals were calculated and a statistical significance was set for p-value < 0.05. Mean age was 32 ± 6 years and 70.9% female). BOS prevalence was 66.3% with 71.4% in female and 53.9% in male (p = 0.002). Of the 232 participants with BOS, 65.7%, 52% and 53.7% had moderate to high emotional exhaustion, depersonalisation and decreased personal accomplishment respectively. Moderate to high PA as well as poor SQ were not significantly associated with BOS while longer sleep duration (> 8h) was associated with a greater odd of BOS. The prevalence of BOS was high among healthcare professionals. While PA showed no protective effects, high sleep duration could increase it risk.

Abstract
The free amino acid - profiles of the pond-cultured giant freshwater prawn, Macrobrachium rosenbergii were evaluated. The M. rosenbergii was collected from the natural pond culture sites that showed reasonably good growth and survival of adults of male, female and stunted animals. Totally 15 amino acids were detected in normal male and female adults. Whereas 14 amino acids were detected in the stunted animals and threonine was not detected in the stunted animal. Three non-essential amino acids, four conditional essential amino acids, and eight essential amino acids were recorded in the tissues of M. rosenbergii. The aspartic acid contributed a higher value in all three tissue samples; 185.3, 138.76, and 274.09 µL/mL in male, female and stunted animals respectively. The arginine was found to be the lowest value in the male (2.5 µL/mL) and in the stunted animals (3.78 µL/mL) but in the normal male the glycine was the lowest value (2.38 µL/mL). In the normal male, tyrosine, serine, and glutamic acid were at the highest concentrations but in the normal female, the glutamic acid, Leucine, and tyrosine contributed to the higher-level amino acids. However, in the stunted one, serine, leucine, and histidine (96.98, 81.62, and 63.59 µl/ml, respectively) showed the same values as glutamic and tyrosine. The overall amount of essential amino acids was higher in female prawns than in male and stunted ones. In contrast, the non-essential amino acid content was higher in the stunted shrimp. Therefore, stunted prawns can be used as good nutritional food for human consumption.

Abstract
Background: Pancreatic cancer (PC) is a malignant digestive system tumor with a very poor prognosis. N6-methyladenosine (m6A) is mediated by a variety of readers and participates in important regulatory roles in PC. Therefore, it is necessary to screen out its specific modification mode from the m6A readers, and deeply explore its mechanism and its pharmacogenomic characteristics, so as to provide a new direction for the precision treatment of PC.
Methods: Based on TCGA-PAAD, PACA-AU, PACA-CA, GSE28735 and GSE62452 datasets, we explored the specific variations of m6A readers at the multi-omics level. An unsupervised consensus clustering algorithm was used to explore the correlation between specific expression patterns of m6A readers in PC and enrichment pathways, tumor immunity and clinical molecular subtypes. Then, the principal component analysis (PCA) algorithm was used to quantify specific expression patterns and screen core gene. Machine learning algorithms such as Bootstrapping and RSF were used to quantify the expression patterns of core gene and construct a prognostic scoring model for PC patients. What’s more, pharmacogenomic databases were used to screen sensitive drug targets and small molecule compounds for high-risk PC patients in an all-around and multi-angle way.
Results: We mapped the multi-omics changes of m6A readers in PC and found that m6A readers, especially IGF2BP family genes, had specific changes and were significantly associated with poor prognosis. Otherwise, two specific expression patterns of the m6A readers were constructed and IGF2BP2 was identified as the core gene. We confirmed that abnormally high expression of IGF2BP2 was associated with enrichment and activation of cell cycle and tumor-related pathways in PC patients. Then, a poor prognostic signature (PPS) including 13 genes (FNDC3B, L1CAM, PLXNA1, HMGA2, FAM110B, FAM83A, COX7A1, PMAIP1, KIF20B, SPDL1, SNCG, TGM2 and MUC16) was constructed. Finally, we identified seven therapeutic targets (FOXM1, PRC1, CCNB1, SLC16A3, CCNA2, GGCX, and AURKA) and two agents (Tipifarnib and Vemurafenib) for high-PPS score patients.
Conclusion: Our study has not only provided new insights into personalized prognostication approaches, but also thrown light on integrating tailored risk stratification with precision therapy based on IGF2BP2-mediated m6A modification patterns.
Simulation of droplet impact dynamics on V-shaped walls
Authors: Wu Guoqiang , Chen Sheng 
Published: January 2023

Abstract
This paper presents the morphological evolution characteristics of a droplet impacting a V-shaped wall by using the lattice Boltzmann method (LBM). Four parameters are investigated comprehensively. The parameters vary over wide ranges: surface wettability (60o ≤ θeq ≤ 120o), Weber number (102.27 ≤ We ≤ 3681.82), bending angle of the V-shaped wall (90o ≤ θ ≤ 180o), and eccentricity ratio (0 ≤ b ≤ 0.5). Two types of collision are observed: deposition and breakage. For breakage, the number of satellite droplets increases against the increment of We. The splashing occurs for a high We. And the lamella ejection is observed on the hydrophilic wall and the neutral wall. The lamella ejection will be slight against the increase of θeq, while it will become obvious against the increment of θ. In addition, the nondimensional spreading length, width, and height are measured and analyzed. A regime map is established based on We and θ.

Abstract

Objective: Cognitive measures are an important primary outcome of pediatric, adolescents, and childhood epilepsy surgery. The purpose of this systematic review and meta-analysis is to assess whether there are long-term alterations (≥ 5 years) in the Full-Scale Intelligence Quotient (FSIQ) of pediatric patients undergoing epilepsy surgery.
Methods: Electronic databases (EMBASE, MEDLINE, and Scopus) were searched for English articles from inception to October 2022 that examined intelligence outcomes in pediatric epilepsy surgery patients. Inclusion criteria were defined as the patient sample size of ≥ 5, average follow- up of ≥5 years, and surgeries performed on individuals ≤ 18 years old at the time of surgery. Exclusion criteria consisted of palliative surgery, animal studies, and studies not reporting surgical or FSIQ outcomes. Publication bias was assessed using a funnel plot and the Quality in Prognosis Studies (QUIPS) toolset was used for quality appraisal of the selected articles. A random- effects network meta-analysis was performed to compare FSIQ between surgical patients at baseline and follow-up and Mean Difference (MD) was used to calculate the effect size of each study. Point estimates for effects and 95% confidence intervals for moderation analysis were performed on variables putatively associated with the effect size.
Results: 21,408 studies were screened for abstract and title. Of these, 797 fit our inclusion and exclusion criteria and proceeded to full-text screening. Overall, seven studies met our requirements and were selected. Quantitative analysis was performed on these studies (N = 330). The mean long-term difference between pre- and post- operative FSIQ scores across all studies was noted at 3.36 [95% CI: (0.14, 6.57), p = 0.04, I2 = 0%] and heterogeneity was low.
Conclusion: To our knowledge, this is the first meta-analysis to measure the long-term impacts of FSIQ in pediatric and adolescent epilepsy patients. Our overall results in this meta-analysis indicate that while most studies do not show long-term FSIQ deterioration in pediatric patients who underwent epilepsy surgery, the observed changes were not clinically significant. Moreover, at the individual patient level analysis, while most children did not show long-term FSIQ deterioration, few had significant decline. These findings indicate the importance of surgery as a viable option for pediatric patients with medically refractory epilepsy.

Published: January 2023

Abstract
We discuss a quantum refrigerator to increase the ground state probability of a target qubit whose energy difference between the ground and excited states is less than the thermal energyof its environment. We consider two types of quantum refrigerators: (1) one extra qubit with frequent pulse operations and(2) two extra qubits without them. These two types of refrigerators are evaluated from the viewpoint of quantum thermodynamics. More specifically,we calculate the heat removed from the target qubit, the work done for the system, and the coefficient of performance (COP), the ratio between the heat ant work.We show that the COP of the second type outperforms that of the first one.Our results are useful to design a high-performance quantum refrigerator cooling down a qubit.
Design of a Novel Dual-Polarized Microwave Sensor for Human Bone Fracture Detection Using Reactive Impedance Surfaces
Authors: Moqadam Aslan Nouri , Kazemi Robab 
Published: January 2023

Abstract
In this paper, a novel miniaturized dual-polarized transceiver sensor using a reactive impedance surface (RIS) is presented for detecting fractures in human bone tissues. A RIS structure comprised of elegantly arranged rectangular patch elements are placed at the back of the radiating square patch antenna. The RIS reduces the overall dimensions of the sensor by 30% compared to a conventional patch resonator. Reducing the size results in better detection of bone fractures. Furthermore, a novel dielectric plano-concave lens is introduced between the patch antenna and the body tissue as a matching medium to concentrate and penetrate higher levels of EM power in the tissues as well as conform the curvy shape of the body. A few via holes, filled with a lossy dielectric material similar to human fat tissue, are embedded in the lens to increase the insertion loss in the presence of the cracked bone for easier crack detection. Because of the higher conductivity of blood filling the crack, insertion loss increases when scanning the damaged area. Without the use of the proposed lens, this increase in loss compared to normal bone is negligible and the crack is undetectable. Hence, by utilizing the proposed lens, it is possible to sense the difference between cracked and normal bones, and as a result, the resolution of the images in the raster scan is improved. In the proposed configuration, two sensors as a transmitter and a receiver are placed opposite each other on the tissue and move along the tissue simultaneously. The amount of EM power collected by the receiver can be determined by measuring the S-parameters; these parameters are used for construction of the images of the fractured bones. Several cases of bone fractures with horizontal and vertical orientations and width of at least 1 mm are evaluated through full-wave simulations. Narrow cracks in the millimeter range are precisely detected and localized with the help of the proposed sensor. The experimental measurements are carried out on a semi-solid modified human mimicking phantom. Scattering parameters are evaluated at each step of the raster scan to sense the difference between the presence or absence of cracks in the bone tissue. Bone fractures are clearly observed in the images constructed from the phases of the insertion losses between two transceiver sensors and from the contrast between the crack and the surrounding tissue. Orientation of the fracture is also determined by switching between two orthogonal polarizations. Great agreement between the experimental and simulation results is observed, which validates the reliability of the proposed system. Stable performance in the vicinity of different human bodies and higher concentration and penetration of power to increase detection accuracy are the prominent features of the proposed sensor.

Abstract
Background
The use of engaging abutments with splinted cement retained restorations with screw access channels is essential to maintain abutment orientation. The purpose of this in vitro study was to determine the maximum degree of divergence between 2 adjacent implants with conical connections that allows insertion and removal of a splinted screw-retained restoration with engaging preparable abutments or titanium base abutments.
Methods
Two implants were aligned in a stone base, one straight and the other at an angle ranging from 0–20 degrees. The implants represented an implant system that had an internal conical connection and a hexed abutment engaging the base of the connection. Two straight preparable engaging cement retained abutments were screwed onto the implants and splinted together using acrylic resin. A total of 11 angles were tested, with 7 specimens for every angle. Evaluation of dislodging force was performed by pulling out the splinted abutments after unscrewing them. This was performed subjectively by 3 blinded investigators who applied a tactile pulling force. A scale of 0–10 was used to estimate the pulling force. Objectively the dislodging force was measured in Newtons using a universal testing machine. A statistical correlation was made between the subjective and objective dislodging force values using Spearman’s rank correlation coefficient.
Results
The mean subjective values increased gradually from 0 to 16 degrees. A sudden rise was noticed at 18 degrees (9.71 ± 0.23) and, at 20 degrees, the investigators were not able to remove the splinted abutments from the implants. The mean objective dislodgement force values increased gradually from 0 to16 degrees and abruptly from 16 degrees (13.57 ± 0.45 N) to 18 degrees (25.40 ± 0.66 N) and 20 degrees (35.22 ± 0.64). The correlation between the subjective and the objective evaluations assessed using the Spearman’s rank correlation coefficient was 0.98 indicating a statistically significant correlation (P < .001). As the objective dislodging force increased, the subjective dislodgement difficulty increased.
Conclusions
Splinting cement retained restorations with screw access channels on engaging abutments is possible when multiple implants with conical connections having an internal flare angle of 8 degrees are used, with implant divergence of up to 16 degrees.
