Abstract
A two-dimensional velocity structure for the mantle down to a depth of 700 km derived from super long-range nuclear explosion seismic data recorded along the Quartz profile in northern Eurasia is presented. The profile extends from the Russian Platform, across Western Siberia to the Altai mountains. A detailed structural image of the lithosphere and asthenosphere shows strong lateral variations along the profile. The subcrustal lithosphere to a depth of 100 km is characterized by lateral variations of the P-wave velocity between 7.7 and 8.7 km/sec. The seismic data are consistent with the Ural mountains having a crustal root. Another important finding in the data is an additional discontinuity in the mantle transition zone at 530 km. This discontinuity could represent one or more phase transitions known to occur at about this depth. At present, the nuclear-seismic records are believed to represent a key data set to prove the existence of this much debated upper mantle discontinuity.

Published: July 2023

Mini combine harvester needs a thresher that paddy and straw inserted into the thresher room. We design Hammer thresher as a part of the mini combine harvester. The research seeks to make a motorized rice thresher that paddy and straw are inserted into the thresher room. The concept of the thresher emanated from the working principles of the hammer mill mechanism, but the operating system is continuous. The result shows a rice thresher with a threshing hammer of diameter 350 mm and length 500 mm and a threshing hammer shaft of diameter 25.4 mm. We design the Components of the machine, and it makes a prototype. The power requirement of the machine was 1 HP. When the shaft thresher rotates, it will produce a beating, friction, and shaking. This process can separate the grain from rice straw and panicles respectively. The capacity of this machine is 132.1-168.0 kg of rice per hour. Therefore, the speed of shaft rotation and area of the straw chute affected threshing efficiency and rice quality.
Etude des constantes biologiques du sang du cerf rusa (Cervus timorensis russa) en Nouvelle-Calédonie. I. Les constantes hématologiques
Authors: Audigé Laurent 
Published: July 2023

Depuis le début de l’année 1987, l’élevage du cerf rusa (Cervus timorensis russa) se développe en Nouvelle-Calédonie. En 1988, au cours d’une opération d’abattage en élevage, l’auteur a réalisé près de 90 prélèvements de sang pour définir les constantes biologiques du sang de cette espèce. En hématologie, l’étude porte sur la numération érythrocytaire (9,32x1012/L), la numération leucocytaire (4,51x109/L), la numération des différentes lignées leucocytaires et la formulation (polynucléaires neutrophiles : 2,08x109/L [46,6 p. 100] ; lymphocytes : 1,75x109/L [38,4 p. 100] ; monocytes : 0,33x109/L [7,5 p. 100] ; polynucléaires éosinophiles : 0,4x109/L [7,46 p. 100] ; polynucléaires basophiles : 0,01x109/L [0,28 p. 100]) ; l’hématocrite (36,8 %), le taux d’hémoglobine (14,1 g/dl), le volume globulaire moyen (40,3 fl), le taux globulaire moyen en hémoglobine (15,3 pg/cellule) et la concentration globulaire moyenne en hémoglobine (38,7 g/dl). L’étude a révélé des variations de ces paramètres en fonction de certains critères physiologiques et des conditions de prélèvement, car le cerf est un animal sensible au stress.
Influence de faibles taux de fertilisation azotée et de coupes intensives sur les pâturages naturels du Plateau de l’Adamaoua au Cameroun
Authors: Pamo E.T. 
Published: July 2023

Il a été démontré dans bien des régions que la fertilisation et l’intensité de pâture ou de coupe affectent le rendement et la qualité des espèces fourragères des pâturages ; mais les données similaires font défaut sur la plupart des parcours de l’Adamaoua. Une étude a donc été conduite à la station de Recherches Zootechniques de Wakwa pour évaluer la réponse des pâturages naturels sur sol ferralitique avec de faibles doses d’azote et d’intensités de coupe. Un essai factoriel avec sept doses d’azote (0, 40, 50, 60, 70, 80 et 90 unités d’azote/ha) et trois intensités de coupes (5 cm, forte ; 10 cm, moyenne et 15 cm au-dessus du sol, faible) a été utilisé à un mois d’intervalle. L’azote était appliqué après la coupe de régularisation et plus tard après chaque coupe. En moyenne, la fertilisation a régulièrement augmenté la production du pâturage naturel, comparé aux témoins de 88 p. 100 en 1985 et 59 p. 100 en 1986. L’ajustement polynomial des données moyennes a également fourni de bons résultats comme le montrent les coefficients de détermination R2 (0,91 en 1985 et 0,78 en 1986) relativement élevés. Lors de la première année d’étude il n’est apparu aucune différence significative entre les trois intensités de coupe. En 1986, en raison de problèmes observés sur le terrain, les différentes intensités de coupe ont produit des résultats divers. La forte intensité de coupe a significativement (P < 0,05) produit plus que la faible. Comme dans plusieurs études antérieures, il sera cependant possible, à la fin de ce travail, de mieux cerner le problème.
A Constructivist Analysis of the Establishment of the AUKUS Security Pact and its Implications for Regional Stability in the Indo-Pacific
Authors: Korwa Johni R.V. , Wambrauw Meyland S. F. 
Published: July 2023

This article attempts to shed light on AUKUS formation based on constructivist perspective and its implications for regional stability in the Indo-Pacific. Using a qualitative approach with a case study method, this article found that the formation of AUKUS is strongly influenced by two fundamental elements of constructivism: identity and interests. Identity refers to the shared ideas among the Anglo-Saxon nations (including Canada and New Zealand). Nevertheless, New Zealand tends not to join AUKUS due to its commitment to non-proliferation, while Canada seems to contribute nothing to the nuclear submarine program. The interests of the AUKUS alliance are: the US desires to strengthen its hegemony in the Indo-Pacific and rebalance China’s domination; the UK craves to become the first European country to enhance alliance cooperation in the Indo-Pacific after Brexit; and Australia’s willingness to modernize its military capability and affirms its commitment to which allies it counts on in the future. The implications of establishing AUKUS might include: undermining the status quo in the region concerning a nuclear-free zone, weakening existing cooperation agreements and reducing mutual trust between traditional allies, and bringing catastrophe to the region by triggering an armed race.

Keywords: AUKUS; China; Constructivism; Indo-Pacific; Regional Stability
Are we following guidelines in inguinal hernia repair? An evaluation of practice patterns in the abdominal core health quality collaborative
Authors: Oyola Anna Malysz , Beeson Seth , Edgerton Colston , Hope William 
Published: July 2023

Aim : The HerniaSurge Group established inguinal hernia repair guidelines to reduce recurrence and chronic pain. We evaluated whether the surgeons of the Abdominal Core Health Quality Collaborative (ACHQC) follow these guidelines and identify areas for improvement.
Methods : A retrospective evaluation of data from the ACHQC database between 2013-2021 using 18,641 eligible subjects undergoing elective and emergent hernia repair with 30-day follow-up. Compliance with a given guideline was defined as following the recommendation in 70% of cases.
Results : Twelve of 19 questions with available data met recommendations based on our above criteria. Eight recommendations with strong evidence and four recommendations with weak evidence were met. The recommendations not met were using the Shouldice technique for any non-mesh open inguinal herniorrhaphy, using local anesthesia for open repair of reducible inguinal hernias, using lightweight mesh, and avoiding the use of prophylactic antibiotics in laparoscopic herniorrhaphy.
Conclusion : Despite varied techniques for inguinal hernia repair, surgeons of the ACHQC follow the majority of the recently published guidelines on the subject. While further research is needed to strengthen the existing guidelines, a standardized approach will facilitate this effort while aiming to reduce negative patient outcomes.

Authors: Putri Sintia Ariska , Mayasari Ulfayani 
Published: July 2023

The low ability of student learning outcomes is because teachers never manipulate the ability of learning outcomes, and many teachers still use conventional learning approaches. The purpose of this study was to determine whether the Group To Group Exchange method has no effect on student learning outcomes on environmental change in one of the Islamic high schools in Medan. This research is a quasi-experimental study with a Nonequivalent pretest-posttest control group design. Data analysis of student learning outcomes used the ttest formula, with the help of SPSS version 25 data processing. Data analysis of student learning outcomes by calculating the average learning outcomes showed that the experimental class using the Group to Group Exchange method was higher than the control class. The prerequisite test proved that the data were normally distributed and homogeneous. The results of the calculation of the ttest test show that tcount is higher than ttable, so there is an influence so that it shows tcount > ttable then Ha2 is accepted. The results of this study indicate that there are influences and differences before and after the application of the Group to Group Exchange method on student learning outcomes on environmental change material in one of the Islamic high schools in Medan so that the findings obtained can be applied by teachers in carrying out learning, especially biology subjects.Abstrak Rendahnya kemampuan hasil belajar siswa disebabkan guru tidak pernah memperdayakan kemampuan hasil belajar dan masih banyak guru yang menggunakan pendekatan pembelajaran konvensional.

The Paradigm of the EMT Process. Tissue-Specific Factors as a Potential Treatment Tool for Prostate Cancer Patients
Authors: Parol-Kulczyk Martyna Ewa , Grzanka Dariusz 
Published: July 2023

Prostate cancer is the most occurred malignant disease in the male population in over one-half of the countries and still constitutes the fifth leading cause of death in 2020, worldwide. Metastatic prostate cancer is a lethal malignancy that mostly is terminated within several years through the patient&#039;s death. Researchers should focus on the phenomenon which is rigorously appertaining to metastatic cascade and operating as an initiator of metastases to provide the knowledge needed to solve the problem of diagnostics and treatment of advanced prostate cancer patients. The epithelial-mesenchymal transition is one such phenomenon. The current review is based mainly on three papers published in 2021, which describe the most important tissue-specific factors managing epithelial-mesenchymal transition and are
discussed with scientific papers published in acknowledged journals. The effect of the current review is the specification of profiles of precise tissue factors predicting the progression of the prostate neoplasm to its metastatic stage in a new edition.

Passive fit of CAD/CAM implant supported screw-retained metal frameworks based on actual versus screwmented ones based on virtual implant position: A randomized in vitro study
Authors: Kamel Mohamed El-Sayed 
Published: July 2023

Abstract
CAD/CAM (computer aided design/ computer aided manufacturing) constructed screw retained implant supported frameworks give solutions for the problems arising from the lost wax technique by improving accuracy, adaptation and passive fit of the final restoration. However, concerns about the passive fit of a pre-implant insertion CAD/CAM constructed framework still exists due to the expected errors in imaging, registration, surgical guide construction, adaptation and hence transferring the planned position intra-orally.
Trends of Carbon Emissions and Foreign Direct Investment: Accounting for Ecological Footprints, Renewable Energy, Globalization and Technological Innovations in BRICS
Authors: Kayani Umar Nawaz , Nasim Ismat , Aysan Ahmet Faruk , Bashir Farrukh , Iqbal Umer 
Published: July 2023

Abstract
This paper explores the relationship between carbon emission (CE) and foreign direct investment (FDI) keeping the ecological footprint, renewable energy, globalization, and technological innovations as exogenous variables. We employ the system of equations in the form of simultaneous equations for the panel of BRICS countries to fully capture the proposed association. This study highlights the importance of ecological footprints for the determination of CE and FDI along with some exogenous and instrument variables. Our empirical findings of explaining CE assert that FDI, technological innovations, and renewable energy significantly help to curtail carbon emissions in selected countries. However, the ecological footprints are causing CE positively which yields an alarming situation in two ways, firstly a high of rate environmental degradation, and secondly the pressure of humans on land is increasing and that is causing to increase in the EF in BRICS. The equation of FDI is presenting the curtailing impact of CE and RER whereas globalization is increasing the investment rate in BRICS. Mineral mining should be controlled and regulated since it has the potential to have a number of negative effects, including soil pollution, acid mine drainage, erosion, biodiversity loss, considerable water resource usage, and problems with wastewater disposal. Nonetheless, recycling mining waste, employing environmentally friendly equipment, stopping illegal mining, and enhancing mining sustainability may all help to lessen the effects of mining on the environment.
Comparison of Chloroplast Genomes and Phylogenetic Analysis of Four Species in Quercus section Cyclobalanopsis
Authors: Chen Xiaoli , Zhang Xuemei 
Published: July 2023

Abstract
The identification in Quercus L. species was considered to be difficult all the time. The fundamental phylogenies of Quercus have already been discussed by morphological and molecular means. However, the morphological characteristics of some Quercus groups may not be consistent with the molecular results (such as the group Helferiana ), which may lead to blurring of species relationships and prevent further evolutionary researches. To understand the interspecific relationships and phylogenetic positions, we sequenced and assembled the CPGs (160715 bp ~ 160842 bp) of four Quercus section Cyclobalanopsis species by Illumina pair-end sequencing. The genomic structure, GC content and IR/SC boundaries exhibited significant conservatism. Six highly variable hotspots were detected in comparison analysis, among which rpoC1, clpP and ycf1 could be used as molecular markers. Besides, two genes (petA, ycf2) were detected to be under positive selection pressure. The phylogenetic analysis showed: Trigonobalanus genus and Fagus genus located at the base of the phylogeny tree; the Quercus genus were distincted to two clades, including five sections. All CTB species clustered into a single branch, which was in accordance with the results of the morphological studies. But neither of group Gilva nor group Helferiana had formed a monophyly. Six CTB species gathered together in pairs to form one branch respectively (Quercus kerrii and Quercus chungii; Quercus austrocochinchinensis with Quercus gilva; Quercus helferiana and Quercus rex). Due to a low support rate (0.338) in the phylogeny tree, the interspecies relationship between the two branches differentiated by this node remained unclear. We believe that Q. helferiana and Q. kerrii can exist as independent species due to their distance in the phylogeny tree. Our study provided genetic information in Quercus genus, which could be applied to further studies in taxology and phylogenetics.
Vibrational Spectroscopy Identifies Myocardial Chemical Modifications in 1 Heart Failure with Preserved Ejection Fraction
Authors: Pioppi Leonardo , Parvan Reza , Samrend Alan , Silva Gustavo Jose Justo da , Paolantini Marco , Sassi Paola , Cataliotti Alessandro 
Published: July 2023

Abstract
Background
Vibrational spectroscopy can be a valuable tool to monitor the markers of cardiovascular diseases. In the present work, we explored the vibrational spectroscopy characteristics of the cardiac tissue in an experimental model of heart failure with preserved ejection fraction (HFpEF). The goal was to detect early cardiac chemical modifications associated with the development of HFpEF.
Methods
We used the Fourier-transform infrared (FTIR) and Raman micro-spectroscopic techniques to provide complementary and objective tools for the histological assessment of heart tissues from an animal model of HFpEF. A new sampling technique was adopted (tissue print on a CaF2 disk) to characterize the extracellular matrix.
Results
Several spectroscopic markers (lipids, carbohydrates, and glutamate bands) were recognized in the cardiac ventricles due to the comorbidities associated with the pathology, such as obesity and diabetes. Besides, abnormal collagen cross-linking and a decrease in tryptophan content were observed and related to the stiffening of ventricles and to the inflammatory state which is a favourable condition for HFpEF.
Conclusions
By the analyses of tissues and tissue prints, FTIR and Raman techniques were shown to be highly sensitive and selective in detecting changes in the chemistry of the heart in experimental HFpEF and its related comorbidities. Vibrational spectroscopy is a new approach that can identify novel biomarkers for early detection of HFpEF.
Implementing PCR testing in general practice – a qualitative study using normalization process theory
Authors: Shahrzad Sinead , Balasubramaniam Kirubakaran , Kousgaard Marius Brostrøm , Thilsing Trine , Søndergaard Jens , Overbeck Gritt 
Published: July 2023

Abstract
Background
The covid-19 pandemic brought attention to a need of rapid testing of large populations. Experiences from community-based testing settings show that there can be workload difficulties, logistical challenges, and socioeconomic downsides to large scale Polymerase Chain Reaction (PCR) testing. Alternative testing arenas have therefore been considered. Rapid point-of-care (POC) PCR test methods have since been developed and could have potential to surveille respiratory viral infections. It is, however, unknown if PCR testing can be successfully implemented routinely in general practice. The aim of this study is therefore to asses factors that enable and inhibit the implementation of point-of-care PCR testing for acute respiratory tract infection in general practice.
Methods
Fourteen general practices in the east Zealand area in Denmark were included in the study and given access to point-of-care PCR testing equipment during a flu season. The participating clinics were initially trained in the use of a POC PCR testing device and then spent 6 weeks testing it. We conducted qualitative interviews with general practitioners (GPs) and their staff, before and after the testing period, specifically focusing on their clinical decision-making and internal collaboration in relation to POC PCR testing. We used normalization process theory to design the interview guides and to analyze the data.
Results
Professionals reported no clinical need for a POC PCR testing device in a non-pandemic clinical setting. Results were delivered faster, but this was only timesaving for the patient and not the GP, who had to perform more tasks.
Conclusion
In its current form, the added diagnostic value of using a POC PCR tester in clinical practice does not justify the increased work connected to the usage of the diagnostic procedure in daily practice.
