HIGHLIGHTS

This study aimed to identify the characteristics of Gestational Trophoblastic Neoplasia (GTN).
GTN is chemosensitive, but without appropriate therapy and follow-up, GTN will develop into complications and fatalities.

ABSTRACT
Objective: Gestational Trophoblastic Neoplasia (GTN) is a pregnancy-related malignancy due to abnormal proliferation of trophoblastic tissue. This study aimed to identify the characteristics of patients with GTN to help diagnose cases of GTN earlier and provide better treatment.
Materials and Methods: This was a descriptive retrospective study on medical records of patients with GTN in Dr. Soetomo General Academic Hospital Surabaya, Indonesia, during the period of January 2018 to December 2020 with a total sampling technique. There were 41 patients with GTN included as study subjects.
Results: Forty-one cases of GTN met the inclusion criteria out of the fifty medical records collected. The majority of patients aged 21 – 30 years old (34%) and had parity status without data (42%). Regarding the clinical profile based on prognostic factors, the predominant patients (71%) also had no data about the time interval between the end of the last pregnancy and the first time diagnosed by GTN, Those with more than 100,000 mIU/ml of beta-hCG levels were 32%, and those without metastases were 41.5%. Most patients belonged to the low-risk group (49%) and received chemotherapy (71%) with the MTX LD regimen (69%).
Conclusion: GTN occurred predominantly in reproductive women that belonged to the low-risk group. Furthermore, chemotherapy is one of the chosen therapy for those patients.
Item-response theoretical examinations of a lot of bullshit: Evaluations of measures of bullshit production and reception
Authors: Blötner Christian 
Published: April 2023

Abstract
Scholars developed and probed measures of individual receptivity to and production of ambiguous, empty, or otherwise deceptive information that is intended to gain advantages or avoid disadvantages (so-called bullshit). All recent endeavors to scale development and evaluation were limited to classical test theory, but no study has yet applied item response theory (IRT). In a sample of 525 participants, most of the items of the Bullshit Receptivity Scale, the Scientific Bullshit Receptivity Scale, and the Bullshitting Frequency Scale revealed appropriate IRT properties in the polytomous graded response model. However, in some cases, sufficient information could be obtained only within relatively narrow spectra, or gaps of obtainable information occurred along the spectra. Furthermore, bullshit and real information statements did not function equally well. Last, statistical concerns with frequently employed bullshit sensitivity scores were discussed and recommendations for further efforts concerning item development were expressed.
Morocco's Coal to Clean Journey: Optimised Pathways for Decarbonisation and Energy Security
Authors: Harland Natasha , Jansen Malte , Yeganyan Rudolf , Tan Naomi , Cannone Carla , Howells Mark 
Published: April 2023

Abstract
Morocco depends on imported fossil fuels for 90% of its primary energy supply. This makes the country vulnerable to unstable fuel prices and supply cut-offs, and the reliance on fossil fuels releases CO2 emissions which contribute to climate change. Renewable energy expansion, facilitated by Morocco’s high potential for solar and wind capacity, could allow the country to improve its energy security and decarbonise its energy system, in line with its response to the Paris Agreement.

This study uses OSeMOSYS (the Open Source Energy Modelling System) to produce six cost-minimised decarbonisation scenarios for Morocco that consider energy independence. The results show that Morocco can achieve most of its decarbonisation targets through bulk wind and solar energy, with a coal phase-out being possible by 2031 at the latest. Natural gas is replaced by biomass and nuclear energy, with some evidence that fuel imports may stay relevant for the foreseeable future.

We conclude with policy recommendations. The study can provide insights for policymakers and stakeholders in Morocco's energy sector to achieve optimal pathways for decarbonisation.
Highly efficient removal of polycyclic aromatic hydrocarbons from water using organophilic clays obtained from simultaneous ion exchange and grafting
Authors: Funes Israel G. A. , Carlos Luciano , Parolo Maria E 
Published: April 2023

Abstract
The present work analyses the polyaromatic hydrocarbons (PAHs) removal from water through batch adsorption processes, using two low-cost surfactant-grafted bentonites (Mt/TPODAC-1.5 and H5-Mt/TPODAC-1.5).These materials were prepared via a modification of montmorillonite (Mt) and acid-activated bentonite (H5-Mt) by intercalation and grafting of (3-trimethoxysilylpropyl) octadecyldimethylammonium chloride (TPODAC). Anthracene (ANT) was used as PAH model to assess the sorption capacity of each material. It was found that the selective modification of clay mineral has higher adsorption capacity for ANT compared with raw clay. Mt/TPODAC-1.5 and H5-Mt/TPODAC-1.5 removed 91 % and 85 % of ANT from water, respectively, while the raw bentonite (Mt) removed only 22 % under the same conditions. The adsorption isotherms were S-shaped and were fitted by the Frumkin-Fowler-Guggenheim (FFG) model, exhibiting an adsorption cooperative behaviour. The results indicate that hydrophobic and cation-π interactions ruled the ANT sorption on the modified clays. Simultaneous adsorption experiments with a mixture of 16 PAHs showed a high removal capacity of both modified clays. The promising results obtained in this work highlights the use of the TPODAC-grafted bentonite as potential sorbents to removal PAHs in a simple, economical, and environmentally friendly way.

Published: April 2023

Abstract
Fractures are ubiquitous and lead to catastrophic failure of materials. While fracture in a two-dimensional plane is well understood, all fractures are, in fact, extended and propagate in a three-dimensional space and their behavior is more complex. Here we show that forward propagation of a fracture front always occurs through an initial rupture, nucleated at some localized position, followed by very rapid transverse expansion at velocities as high as the Rayleigh-wave speed. We study a circular geometry to achieve an uninterrupted extended fracture front and use fluid to control the loading conditions that determine the amplitude of the forward jump; we find this amplitude correlates with the transverse velocity. Dynamic rupture simulations capture the observations for only high transverse velocity. These results highlight the importance of transverse dynamics in the forward propagation of extended fracture.

The release of inhibition model reproduces kinetics and plasticity of neurotransmitter release in central synapses
Authors: Norman Christopher , Krishnakumar Shyam , Timofeeva Yulia , Volynski Kirill 
Published: April 2023

Abstract
Calcium-evoked release of neurotransmitters from synaptic vesicles (SVs) is catalysed by SNARE proteins. The predominant view is that, at rest, complete assembly of SNARE complexes is inhibited (‘clamped’) by synaptotagmin and complexin molecules. Calcium binding by synaptotagmins releases this fusion clamp and triggers fast SV exocytosis. However, this model has not been quantitatively tested over physiological timescales. Here we describe an experimentally constrained computational modelling framework to quantitatively assess how the molecular architecture of the fusion clamp affects SV exocytosis. Our results argue that the “release-of-inhibition” model can indeed account for fast calcium-activated SV fusion, and that dual binding of synaptotagmin-1 and synaptotagmin-7 to the same SNARE complex enables synergistic regulation of the kinetics and plasticity of neurotransmitter release. The developed framework provides a powerful and adaptable tool to link the molecular biochemistry of presynaptic proteins to physiological data and efficiently test the plausibility of calcium-activated neurotransmitter release models.
Analysis on the shadow price of carbon emissions from China’s forestry fruit industry ---taking peaches as an example
Authors: Yang Yang , Chen Chao 
Published: April 2023

Abstract
The shadow price of carbon emissions can measure the marginal output effect under the carbon emission regulation and is also one of the key indicators to construct a low-carbon development path for production units. Currently, international research on shadow price is focused on the industrial and energy sectors. However, in the context of carbon peaking and carbon neutrality targets in China, the use of shadow price to study the cost of reducing emissions from agricultural production, especially forestry fruit industries, is significant. In this paper, we use a parametric approach to construct the quadratic ambient directed distance function. Using the input-output data of peach, we then calculate the environmental technical efficiency and shadow price of carbon emissions from peach production in Guangxi, Jiangsu, Shandong and Anhui provinces, and further estimate the values of green output in each province. The results show that: (i) the environmental technical efficiency of peach production in Jiangsu province is the highest among the four provinces, and that in Guangxi province is the lowest; and (ii) the marginal cost of reducing carbon emissions from peach production in Guangxi province is the lowest among the four provinces, and that in Sichuan province is the highest; and (iii) the green output value of the peach industry in Jiangsu province is the highest among the four provinces, while that in Guangxi province is the lowest. To effectively reduce the carbon emissions during peach production without affecting economic benefits, Areas with "low cost and low efficiency" are advised to increase the application of green environmental technologies while reducing the production input during peach production. While, in areas with "high cost and low efficiency", we should increase the application of green environmental technologies, but not easily reduce the production input in the peach production process. The proposal for the peach production could also be extended to the entire forestry fruit industries.
Practice Design of Ship Thin Section Considering Prevention of Welding Induced Buckling
Authors: Zhou Hong , Yi Bin , Wang Jiangchao , Shen Chaonan 
Published: April 2023

Abstract

The lightweight fabrication of thin-walled cabin sections is popular for advanced ships, and the dimensional tolerance generated by welding buckling significantly influences the fabrication accuracy and schedule with post-straightening. A typical thin section employed in the superstructure of a high-tech passenger ship is considered as the research object. Conventional fabrication procedures and welding conditions were examined beforehand with combined thermal elastic plastic (TEP) and elastic FE computations based on theory of welding inherent deformation, while welding buckling was represented with identical behavior compared with fabrication observation. Actually, there are usually two methods to prevent welding buckling with advanced fabrication. Stiffeners with optimized geometrical features and excellent elasticity moduli were assembled to enhance the rigidity of the ship thin section, and less welding inherent deformation with advanced welding methods can be employed to reduce mechanical loading. Computational results show that either less in-plane welding inherent strain or higher structural rigidity can reduce the magnitude of welding induced buckling, and avoid the generation of welding induced buckling during lightweight fabrication.
Transitioning to Plant-based Diets: Exploring the Environmental Nutrition Performance of 24 Composite Diet Scenarios

Published: April 2023

Abstract
The potential environmental and nutritional benefits of plant-based dietary shifts require thorough investigation to outline suitable routes to achieve these benefits. Whereas dietary consumption is usually in composite forms, sustainable healthy diet assessments have not adequately addressed composite diets. In this study, we build on available data in the Food4HealthyLife calculator to develop 3 dietary concepts (M) containing 24 model composite diet scenarios (S) assessed for their environmental and nutritional performances. The Health Nutritional Index (HENI) and Food Compass scoring systems were used for nutritional quality profiling and estimates of environmental impact were derived from previously reported midpoint impact values for foods listed in the What We Eat in America database. The diets were ranked using the Kruskal‒Wallis nonparametric test, and a dual-scale data chart was employed for a trade-off analysis to identify the optimal composite diet scenario. The results showcased a distinct variation in ranks for each scenario on the environment and nutrition scales, describing an inherent nonlinear relationship between environmental and nutritional performances. However, trade-off analysis revealed a diet with 10% legumes, 0.11% red meat, 0.28% processed meat and 2.81% white meat could reduce global warming by 54.72% while yielding a diet quality of 74.13 on the Food Compass Scoring system. These observations provide an interesting forecast of the benefits of transitioning to an optimal plant- and animal-based dieting pattern, which advances global nutritional needs and environmental stewardship among consumers.
Reduction of ASZ size and enhancement of mechanical properties of TLP bonded IN718 joint using post bond heat treatment process
Authors: Tarai Uttam Kumar , Pal Sukhomay , Robi P S 
Published: April 2023

Abstract
Transient liquid phase (TLP) bonding can be used to join Inconel 718 superalloy because the bond properties are similar to the parent material properties and little melting of base material. Presence of centerline eutectic and boride precipitates in the microstructure of the TLP bonded Inconel 718 joints affects mechanical properties of the joints. The eutectics and borides should be minimized to enhance the mechanical properties of the bond. This can be achieved to a great extent by prolonged isothermal holding. However, it can induce adverse effects by modifying the microstructure of the base material. Post bond heat treatment (PBHT) processes can be implemented to improve the mechanical properties without inducing any harmful effect of prolonged heating. In the present work, the effect of PBHT technique (i.e. solution treatment and double aging) on the microstructural evolution and improvement in mechanical properties were investigated. The ultimate tensile strength (UTS) and microhardness of TLP bond before and after the PBHT were analyzed and compared with the as-received workpiece. FESEM, FETEM and XRD analysis were used to quantify different precipitates formed during PBHT of TLP bond. The results showed that the PBHT improved the microstructure and mechanical properties of the bonded samples. After the solution treatment and double aging, a maximum UTS of 1210 MPa was obtained, which correspond to a 113.5% increase. The improvement of bond strength was attributed to increase volume fraction of γ' and γ" type strengthening phases during double aging and a decrease in the fraction of Nb-Mo type borides in the diffusion affected zone.
