Published: April 2024

Arkeolojik ve antropolojik açıdan bir birey, aile veya grubun yaşadığı sabit yer/alan olarak tanımlanabilecek olan mekânın uzun süreli kullanımı ve birtakım yapıların aynı alana tekrar tekrar inşa edilmesi arkeolojik açıdan bir mimari devamlılık olarak yorumlanmaktadır. Söz konusu devamlılık, Yakındoğu neolitiğinde, yapıların sadece teknik bir mimari sürekliliğini temsil etmediği öne sürülmektedir. Bu bağlamda mimari devamlılık, herhangi bir mekânın sahip olabileceği olası bir aidiyet duygusu ile ilişkilendirilmekte ve olası bir aidiyet anlayışının metaforik ölümsüzlüğünün somutlaştırılmış hali olarak yorumlanmaktadır. Yukarı Dicle Vadisi’nde bulunan ve Çanak Çömleksiz Neolitik Dönem’in ilk evresine tarihlenen (PPNA) mimari öğelerin açığa çıkarıldığı Çemka Höyük yerleşim yerinde yapılan kazılar sonrası söz konusu mekânsal devamlılık üzerine yeni veriler elde edilmiştir. Çemka Höyük’ünün sunmuş olduğu veriler erken yerleşimlerde ortaya çıkarılan mimari ve kültür arasında ilişkilendirmelerde oldukça önemli sonuçlara değinmekle birlikte yerleşim alanı içinde bireysel veya kamusal olguları da gözler önüne sermektedir. Çemka Höyük’ü mimarisi, özellikle mekân (bireysel ve kamusal), kültürel aidiyet ve inanç gibi oluşumlarla birlikte düşündüğümüzde Neolitik hafıza konusunda önemli bilgiler sunmaktadır. Keza yerleşimin Epi-Paleolitik Dönem sonundan Çanak-Çömleksiz Neolitik A evresi sonuna kadar bir devamlılık sunmasından dolayı erken yerleşimlerde bu durumun daha iyi anlaşılmasına vesile olacaktır.

Authors: Parent Rosalie , Turgeon Rose , Côté Julia , Audet Jean-Sébastien , Lebel Jessica , Belleville Geneviève
Published: April 2024

Les victimes d’agressions sexuelles (AS) appartenant à certains groupes sociodémographiques vulnérables rapportent davantage de symptômes de trouble de stress post-traumatique (TSPT), d’anxiété et de dépression ainsi que de cognitions post-traumatiques. Toutefois, peu d’études prennent en compte ces caractéristiques sociodémographiques simultanément et considèrent qu’elles peuvent s’entrecouper. Afin d’investiguer l’influence des caractéristiques sociodémographiques et du cumul des vulnérabilités (intersectionnalité) sur les conséquences psychologiques des victimes d’AS, 483 adultes ont été sondés. Ils ont rempli le Posttraumatic Cognitions Inventory (PTCI), le Posttraumatic Stress Disorder Symptoms Checklist for DSM-5 (PCL-5), le Generalized Anxiety Disorder-7 (GAD-7) et le Patient Health Questionnaire-9 (PHQ-9). Des ANOVA à plan simple ont montré des différences quant à la sévérité des symptômes et des cognitions post-traumatique selon le niveau d’éducation, le sexe, le genre, le statut relationnel, le pays et la langue maternelle. Des régressions linéaires multiples ont indiqué que le genre, la langue maternelle et le statut relationnel sont de meilleurs prédicteurs pour les résultats aux GAD-7, PHQ-9 et PTCI respectivement. Le cumul des vulnérabilités s’est révélé le meilleur prédicteur pour le PCL-5. Les résultats sont limités par une faible puissance statistique, mais ont permis d’explorer la pertinence de l’inclusion des variables de vulnérabilité dans le concept d’intersectionnalité.

The administration of indigenous justice in Ecuador is characterized by having different schemes and ways of resolving a conflict; That is to say, each Aboriginal community and nationality applies indigenous justice according to its worldview, customs, and traditions; however, in general, the principle of innocence that emanates from positive law is also observed within ancestral jurisdiction. The objective of the manuscript is to critically analyze the procedure applied in the administration of indigenous justice to determine whether the principle of presumption of innocence is guaranteed. To carry out this activity, the inductive, analytical, customary, and descriptive method is used; Due to the vision, the objectives, and the complexity, a mixed qualitative-quantitative approach is assumed; It is pure, dogmatic, legal analytical, and descriptive legal; non-experimental design. The population involved is made up of Constitutional Guarantees Judges and indigenous authorities, to whom a six-question multiple choice questionnaire is applied. The results indicate that the investigations and tests determine the innocence or not of the accused, on the other hand, the main evidence that is analyzed within indigenous justice to determine the guilt of the offender is the testimony and background of the offender, this allows conclude by pointing out that if the principle of presumption of innocence is guaranteed in the administration of indigenous justice.

An inverse model to correct for the effects of post-depositional processing on ice-core nitrate and its isotopes: model framework and applications at Summit, Greenland, and Dome C, Antarctica
Authors: Jiang Zhuang , Alexander Becky , Savarino Joel , Geng Lei
Published: April 2024

Abstract. Comprehensive evaluation of the effects of post-depositional processing is a prerequisite for appropriately interpreting ice-core records of nitrate concentration and isotopes. In this study, we developed an inverse model that uses archived snow/ice-core nitrate signals to reconstruct primary nitrate flux (i.e., the deposition flux of nitrate to surface snow that originates from long-range transport or stratospheric input) and its isotopes (δ15N and Δ17O). The model was then applied to two polar sites, Summit, Greenland, and Dome C, Antarctica, using measured snowpack nitrate concentration and isotope profiles in the top few meters. At Summit, the model successfully reproduced the observed atmospheric δ15N(NO3-) and Δ17O(NO3-) and their seasonality. The model was also able to reasonably reproduce the observed snowpack nitrate profiles at Dome C as well as the skin layer and atmospheric δ15N(NO3-) and Δ17O(NO3-) at the annual scale. The calculated Fpri at Summit was 6.9 × 10−6 kgN m2 a−1, and the calculated Δ17O(NO3-) of Fpri is consistent with atmospheric observations in the Northern Hemisphere. However, the calculated δ15N(NO3-) of Fpri displays an opposite seasonal pattern to atmospheric observations in the northern mid-latitudes, but it is consistent with observations in two Arctic coastal sites. The calculated Fpri at Dome C varies from 1.5 to 2.2 × 10−6 kgN m−2 a−1, with δ15N(NO3-) of Fpri varying from 6.2 ‰ to 29.3 ‰ and Δ17O(NO3-) of Fpri varying from 48.8 ‰ to 52.6 ‰. The calculated Fpri at Dome C is close to the previous estimated stratospheric denitrification flux in Antarctica, and the high δ15N(NO3-) and Δ17O(NO3-) of Fpri at Dome C also point towards the dominant role of stratospheric origin of primary nitrate to Dome C.
Short large-amplitude magnetic structures (SLAMS) at Mercury observed by MESSENGER
Authors: Karlsson Tomas , Plaschke Ferdinand , Glass Austin N. , Raines Jim M.
Published: April 2024

Abstract. We present the first observations of short large-amplitude magnetic structures (denoted SLAMS) at Mercury. We have investigated approximately 4 years of MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) data to identify SLAMS in the Mercury foreshock. Defining SLAMS as magnetic field compressional structures, with an increase in magnetic field strength of at least twice the background magnetic field strength, when MESSENGER is located in the solar wind, we find 435 SLAMS. The SLAMS are found either in regions of a general ultra-low frequency (ULF) wave field, at the boundary of such a ULF wave field, or in a few cases isolated from the wave field. We present statistics on several properties of the SLAMS, such as temporal scale size, amplitude, and the presence of whistler-like wave emissions. We find that SLAMS are mostly found during periods of low interplanetary magnetic field strength, indicating that they are more common for higher solar wind Alfvénic Mach number (MA). We use the Tao solar wind model to estimate solar wind parameters to verify that MA is indeed larger during SLAMS observations than otherwise. Finally, we also investigate how SLAMS observations are related to foreshock geometry.
Picoplanktonic methane production in eutrophic surface waters
Authors: Tenorio Sandy E. , Farías Laura
Published: April 2024

Abstract. Over the past decade, extensive research has delved into the methane (CH4) paradox, which involves aerobic CH4 production. We present noteworthy observations of CH4 oversaturation within the surface layer of the central Chile upwelling zone (36° S, 73° W) over two consecutive seasonal cycles (2018–2021). Complementing these observations, CH4 cycling experiments were conducted, utilizing distinct plankton fractions (encompassing the natural planktonic community, fractions < 150, < 3 and < 0.2 µm), in different productivity periods of phytoplanktonic production and composition throughout the year. Our findings underscore the pivotal role of picoplankton (< 3 µm) in CH4 production on the ocean surface, contrasting with the limited contribution of larger microorganisms (< 150 µm). Notably, incubations with methylated substrates, such as methylphosphonic acid (MPn) and trimethylamine (TMA), induce heightened CH4 production within the picoplanktonic fraction. This phenomenon is consistently observed during both upwelling (austral spring–summer) and non-upwelling (winter) seasons, with significance in the latter period, when Synechococcus sp. exhibits notably high relative abundance. Long-term microcosm experiments highlight the crucial roles played by heterotrophic bacteria and cyanobacteria in methylotrophic methanogenesis. This process enhances CH4 production, facilitated by the recycling of dissolved organic carbon (DOC). Picoplankton emerges as a pivotal factor influencing the recycling of methylated substrates, and it is responsible for maintaining CH4 supersaturation. These findings provide valuable insights into the biogeochemical processes driving CH4 dynamics, particularly in highly productive upwelling areas.
Investigating Carbonyl Compounds above the Amazon Rainforest using PTR-ToF-MS with NO+ Chemical Ionization

Published: April 2024

Abstract. The photochemistry of carbonyl compounds significantly influences tropospheric chemical composition by altering the local oxidative capacity, free radical abundance in the upper troposphere, and formation of ozone, PAN, and secondary organic aerosol particles. Carbonyl compounds can be emitted directly from the biosphere into the atmosphere and are formed through photochemical degradation of various precursor compounds. Aldehydes have atmospheric lifetimes of hours to days, in contrast to ketones, which persist for up to several weeks. While standard operating conditions for proton transfer time‑of‑flight mass spectrometer (PTR-ToF-MS) using H3O+ ions are unable to separate aldehydes and ketones, the use of NO+ reagent ions allows for the differential detection of isomeric carbonyl compounds with a high time resolution. Here we study the temporal (24 h) and vertical (80–325 m) variability of individual carbonyl compounds in the Amazon rainforest atmosphere with respect to their rainforest-specific sources and sinks. We found strong sources of ketones within or just above the rainforest canopy (acetone, MEK, and C5-ketones). A common feature of the carbonyls was nocturnal deposition observed by loss rates, most likely since oxidized volatile organic compounds are rapidly metabolized and utilized by the biosphere. With NO+ chemical ionization, we show that the dominant carbonyl species include acetone and propanal, which are present at a ratio of 1:10 in the wet–to–dry transition and 1:20 in the dry season.

Published: April 2024

Abstract. The increasing amount of data in meteorological science requires effective data reduction methods. Our study demonstrates the use of advanced scientific lossy compression techniques to significantly reduce the size of these large datasets, achieving reductions ranging from 5x to over 150x, while ensuring data integrity is maintained. A key aspect of our work is the development of the 'enstools-compression' Python library. This user-friendly tool simplifies the application of lossy compression for Earth scientists and is integrated into the commonly used NetCDF file format workflows in atmospheric sciences. Based on the HDF5 compression filter architecture, 'enstools-compression' is easily used in Python scripts or via command line, enhancing its accessibility for the scientific community. A series of examples, drawn from current atmospheric science research, shows how lossy compression can efficiently manage large meteorological datasets while maintaining a balance between reducing data size and preserving scientific accuracy. This work addresses the challenge of making lossy compression more accessible, marking a significant step forward in efficient data handling in Earth sciences.

Abstract. The wflow_sbm hydrological model, recently released by Deltares, as part of the Wflow.jl (v0.7.3) modelling framework, is being used to better understand and potentially address multiple operational and water resource planning challenges from a catchment scale to national scale to continental and global scale. Wflow.jl is a free and open-source distributed hydrological modelling framework written in the Julia programming language. The development of wflow_sbm, the model structure, equations and functionalities are described in detail, including example applications of wflow_sbm. The wflow_sbm model aims to strike a balance between low-resolution, low-complexity and high-resolution, high-complexity hydrological models. Most wflow_sbm parameters are based on physical characteristics or processes, and at the same time wflow_sbm has a runtime performance well suited for large-scale high-resolution model applications. Wflow_sbm models can be set a priori for any catchment with the Python tool HydroMT-Wflow based on globally available datasets and through the use of point-scale (pedo)transfer functions and suitable upscaling rules and generally result in a satisfactory (0.4 ≥ Kling–Gupta efficiency (KGE) < 0.7) to good (KGE ≥ 0.7) performance for discharge a priori (without further tuning). Wflow_sbm includes relevant hydrological processes such as glacier and snow processes, evapotranspiration processes, unsaturated zone dynamics, (shallow) groundwater, and surface flow routing including lakes and reservoirs. Further planned developments include improvements on the computational efficiency and flexibility of the routing scheme, implementation of a water demand and allocation module for water resource modelling, the addition of a deep groundwater concept, and computational efficiency improvements through for example distributed computing and graphics processing unit (GPU) acceleration.

PARAMETERS OF THE PERTURBED STATE OF THE DENDRITE TIP
IN DEEPLY SUPERCOOLED NICKEL AND COPPER MELTS
Authors: SHABLOVSKY O. , KROLL D.
Published: April 2024

The object of study is the morphological stability of the tip of a free dendrite in a supercooled melt of a pure
substance. Areas of deep supercooling are considered: for nickel DT > 166 K, for copper – DT > 180 K. A distinctive
feature of the processes being studied is the presence of two propagation velocities of small disturbances
(velocities of “sound”). The dependences of these rates on the supercooling of the melt were determined. The periodic
and coordinate-aperiodic modes of perturbation of the growth line have been studied in detail. For these stable
regimes, the possibility of observing the same speed of the disturbance wave in two processes, differing from each
other in the size of the spatial inhomogeneity of the background in front of the wave and the characteristic wave
attenuation times, was discovered. It is shown that aperiodic instability appears if, after the passage of the wave
front, the width of the growth line inhomogeneity zone decreases. The resonant excitation mode of the dendrite tip
demonstrates important differences between the properties of the nickel and copper melts. First of all, this relates
to the temperature dependences of the resonant frequency and the speed of a standing wave formed in the vicinity
of the vertex. Numerical calculations are presented and graphic information is presented illustrating the patterns
of growth of nickel and copper dendrites.
ELECTRODYNAMIC RESPONSE OF ANISOTROPIC MEDIUM OVER HYDROCARBONS
TO THE INFLUENCE OF PROBING SIGNALS
Authors: YANUSHKEVICH V.
Published: April 2024

A study was carried out of the electrodynamic response of an anisotropic medium over hydrocarbons under
the influence of probing signals for pulsed and dual-frequency modes with a predominance of high-frequency
signals. The characteristics of the geological profile above hydrocarbon deposits were studied using pulse signals
depending on the carrier frequency and period of the radio pulse. For the dual-frequency signal mode, the dependences
of the material and phase components of the surface impedance of the studied medium over oil and gas fields
were modeled depending on the amplitude and frequency ratios. It has been established that an increase in the
dielectric constant of the geological profile above the deposits leads to a decrease in resonance frequencies and
the values of the absolute component of surface impedance Ż11. The revealed manifestations of anomalous effects
expand information about the characteristics of the environment above deposits under the influence of pulsed
electromagnetic waves and are of practical interest for exploratory geophysics. The results obtained can be used
for electrical prospecting when creating equipment for detecting oil and gas fields.

English Language Teaching & Saudi Arabia Vision (2030): A Critical Scrutiny
Authors: Ndiaye Amara , Ullah Farhad , Lebbada Djyad , Mohammed Elsiddig Babiker
Published: April 2024

The primary purpose of this research paper has been to argumentatively and critically scrutinize how ELT and Vision 2030, due to their relational nature, have mutually impacted each other through the visible paradigm shift from the relatively long-established system of Teaching and learning English in the Kingdom to the 2030's educational target needs. In other words, the authors of this research investigate whether ELT influences the Saudi Vision regarding foreign language education or vice versa. The authors of this paper have based this research on their background knowledge and theoretical concepts underpinned by existing literature and research article analysis.The authors have found out through methodologies, curricula, Course contents, and course specifications that English Language Teaching has been considered one of the primary keys to achieving the Saudi Vision's clearly stated objectives. Due to the holistic approach of this Saudi strategic vision, the authors have discovered that English language teaching and English as a Foreign Language have not been sidelined but still appear to be moving at a very lethargic pace. Hence, there is an urgent need for the Saudi Arabia educational authorities to come up with ways to face some constraints weighing heavily on the vision’s success. In addition, this theoretical research has scrutinized the giant steps that Saudi Arabian authorities have been making in transitioning from a hybrid English Language Teaching system trapped for a long time in several sociocultural constraints to a more tailored and customized model in line with Vision 2030 target needs.

The Bracon hebetor is an essential natural enemy in suppressing the coconut black-headed caterpillar (BHC) Opisina arenosella, which was common in coconut field in Ben Tre province. Under laboratory conditions, with six-instar larvae of BHC as a host, the adult body of B. hebetor was yellow-brown and the male’s antennae were longer than those of the female, with oblong and rectangular shapes consisting of 17 - 20 segments, while the female’s antennae were square-shaped with 11 - 14 segments. The abdomen of B. hebetor was pale yellow, with its last segment being dark brown. Females of B. hebetor were larger than males. The average body length of female and male was 3.2 ± 0.17 mm and 3.0 ± 0.18 mm, respectively. The average body length of 2-day-old pupae was 3.0 ± 0.20 mm and that of 3-day-old ones was 3.5 ± 0.21 mm. The average egg length was 0.7 ± 0.07 mm. The findings of this study helped provide information on the identification of B. hebetor larval parasitic wasps on the BHC host, aiding in the search for natural enemies of BHC in coconut fields. Additionally, the research also facilitated the exploration of the biological and ecological aspects of this natural adversary in Vietnam.

The study was carried out to determine the antibacterial activity of protein hydrolysates from black soldier fly (Hermetia illucens) larva (PHBSF) on some pathogenic bacteria including E. ictaluri, A. hydrophila, A. verroni, and S. agalactiae on freshwater fish. The results showed that the tested bacteria were highly sensitive with significant difference (P < 0.05) in diameter clear zone compared to the negative control at the tested concentrations of 20, 35, and 70 mg/100 µL. Particularlly, E. ictaluri was sensitive at all three test concentrations with the diameter of clear zones following 14.0 ± 1.0, 18.7 ± 0.7, and 20.7 ± 0.7 mm, respectively. A. veronii and S. agalactiae were sensitive at concentrations of 35 and 70 mg/100 µL, and A. hydrophila with a clear zone diameter of 14.3 ± 0.3 mm at the concentration of 70 mg/100 µL. The PHBSF was able to kill A. veronii and S. agalactiae with MIC (minimum inhibitory concentration) = MBC (minimum bactericidal concentration) = 44 mg/mL, while E. ictaluri and A. hydrophila were inhibited at MIC 44 mg/mL, and MBC was 88 mg/mL. These results indicated that PHBSF could be potentially used to prevent fish diseases caused by E. ictaluri, A. hydrophila, A. verroni, and S. agalactiae.

Published: April 2024

This study aimed to investigate the effect of water hardness on the fertilization rate, hatching rate, survival rate, and deformity rate of common carp larvae. In the experiment, fertilized eggs of silver carp were incubated in different water hardness levels of 70, 100, 130, 160, & 190 mg CaCO3/L, with a stocking density of 400 eggs/L. The experimental results showed that the fertilization rate was high (78.0 - 79.3%) and did not show significant differences between the treatments (P > 0.05). The hatching rate ranged from 41.0 to 54.0% and larvae stage had the highest survival rate of 54.0% at 70 mg CaCO3/L. The deformity rate of larvae ranged from 5.7 to 74.3% with the lowest observed at the 70 mg CaCO3/L. From the results of the study, it can be assumed that silver carp eggs should be incubated in an aquatic environment with a water hardness of 70 mg CaCO3/L.

Published: April 2024

The study of conjunctival graft surgery for treating corneal ulcers in dogs was conducted at Alpha Pet Veterinary Clinic and Bang Pham Veterinary Hospital from August 2021 to August 2022. Dogs were clinically examined with corneal ulcers and corneal perforations, corneal reflexes, and then fluorescein 2% reagent was used to examine and measure the diameter of the corneal damaged area by using Castroviejo calipers. The surgical method of conjunctival stem grafting was applied and evaluated effects of treatment on corneal ulcers in dogs. A total of 3,024 dogs were examined and treated during the study period. There were 195 dogs with eye diseases, accounting for 6.45% of the cases. The rate of corneal ulcers was 15.90% (31/195 cases). Among the corneal ulcer cases, conjunctival graft surgery was performed in 14 cases. The successful rate of conjunctival stem grafting was 71.43%. The complication rate of conjunctival stem grafting was 42.86%, in which 2 cases of mild complications were successfully treated. The average wound healing duration was 39.45 days. The occurrence of complications depended on the types of complication. Mild complications including suture detachment and corneal edema appeared after 2.5 to 5.5 days while corneal epithelial cysts and ocular edema occurred at 22 to 42 days after surgery. Therefore, this method could be used in treatment of corneal ulcers, particularly in cases of deep ulcers or corneal perforations that required to directly connect to blood vessels.

Path planning is an important problem with the the applications in many aspects, such as video games, robotics etc. This paper proposes a novel method to address the problem of Deep Reinforcement Learning (DRL) based path planning for a mobile robot. We design DRL-based algorithms, including reward functions, and parameter optimization, to avoid time-consuming work in a 2D environment. We also designed an Two-way search hybrid A* algorithm to improve the quality of local path planning. We transferred the designed algorithm to a simple embedded environment to test the computational load of the algorithm when running on a mobile robot. Experiments show that when deployed on a robot platform, the DRL-based algorithm in this article can achieve better planning results and consume less computing resources.
Staggered contracts and unemployment during recessions

Published: April 2024

This paper studies the impact of downward wage rigidity on wage and employment dynamics after the outbreak of major recessions in Spain. Downward wage rigidity stems from collective agreements, which set province-sector-skill-specific minimum wage floors for all workers. By exploiting variation in the renewal of collective agreements, we find that those signed before the onset of recessions settle on higher nominal negotiated wage growth than agreements signed afterwards. Leveraging social security data and the distribution of the worker-level bite of minimum wage floors, we document that the negotiated wage rigidity translated into higher wage growth mainly among workers with near-floor wages. Consequently, these workers experienced a substantial and highly persistent increase in the probability of non-employment, but only if they were covered by long-duration collective agreements. Our findings highlight the interplay between rigidity at different parts of the wage distribution and labor market institutions and identify conditions under which collective contract staggering and the inability to renegotiate may amplify aggregate shocks.
