Introduction to the Mechanics of Flow and Transport for Groundwater Scientists
Authors: Klammler Harald
Published: November 2023

Starting from Newton’s laws of motion and viscosity, this book is an introduction to fundamental aspects of fluid dynamics that are most relevant to groundwater scientists. Based on a perspective of driving versus resisting forces that govern the motion of a fluid, the author derives Darcy’s law for flow through porous media by drawing an analogy to Bernoulli’s law for fluid with negligible viscosity. By combining the effects of gravity and pressure, the author identifies hydraulic head as a convenient numerical quantity to represent the force driving groundwater flow. In contrast to the physical derivation of hydraulic head, hydraulic conductivity emerges as a parameter related to the resisting frictional forces between the mobile fluid and the stationary porous medium. These frictional seepage forces also affect the effective stress state of the porous medium, thus establishing a link to soil stability and quicksand formation. Combining Darcy’s law with the law of mass conservation leads the reader to the fundamental equations of saturated groundwater flow. Finally, the effects of capillary forces are included to establish the governing equations for unsaturated and multi-phase flow. Throughout the book, the author focuses on thoroughly illustrating and deriving the equations while applying order of magnitude analyses. This approach makes it possible to extract the most information, for example in terms of the scale of response time, without requiring explicit solutions. A number of boxes and solved exercises contain further details and links to practical applications such as the water table ratio that reflects ‘fullness’ of an aquifer and the performance of slug tests for in situ measurement of hydraulic conductivity. This book makes an important contribution to groundwater science by providing a progressive introductory explanation of the physical mechanics of groundwater flow and the accompanying socioeconomic and ecological problems that may arise.

Published: November 2023

The purpose of this article is to present a model for simultaneous optimization of pricing, marketing, distribution and sales decisions. Due to the high importance of time and costs along the chain, this model will be very attractive. In previous studies, these decisions have not been considered simultaneously. This paper introduces a bi-objective model including utility maximization and profit maximization. Then it was solved using LP metric method in GAMS optimization software and Gurobi Optimizer in Python environment. After solving the model, the decision variables have been obtained and the model has been subjected to sensitivity analysis. Based on the results obtained, it can be concluded that optimizing distribution network elements simultaneously saves time and money and improves distribution network performance. A trade-off matrix and Pareto chart is ​​provided in which the numbers on the main diagonal represent the most optimal state for each objective. In addition, a comparison was made between the results of the GAMS and Gurobi Optimizer in the Python showing that in larger sizes the Gurobi Optimizer delivers the desired results in a more reasonable time. Also, the results show the sensitivity of the model to the competitors' prices.

Authors: V Koventhan , M Tamilselvan , Nandy Sajal
Published: November 2023

In todays increase in population at metro cities there is a need in development of urban transport infrastructures. Due to development in urban transportation, many cities are proposed with metro structure to facilitate the public with modern transport systems. Since the metro cities are highly populated with congested traffic, development of transportation facility with isolated infrastructure for different transportation system is a major challenge. To overcome these issues, the transportation infrastructures can propose with integrated transportation structures like double decker highway structure, double decker metro with highway structures to facilitate the public with modern transport systems. In one of the metro projects at Chennai in India, a double decker integrated elevated viaduct is proposed with a first level highway traffic and second level with metro traffic. In highway bridges, simply supported superstructure with expansion joint is the conventional practice. But, in these conventional type with expansion joint for each span leads to discomfort to riders and huge maintenance issues. There are many studies and development in highway structure with the reduced number of expansion joint by making structures with deck continuity, diaphragm continuity, integral structures are undergoing. However, in integrated structure with single pier / substructure carrying both metro superstructure and highway superstructure is generally proposed with simply supported spans. In this paper, the study on behavior of integrated double decker viaduct with metro and highway structure is endeavored with deck continuity through link slab at highway level superstructure to avoid many numbers of expansion joints and thereby to provide comfort riding to the public, cost saving during construction and less maintenance cost. An analytical study using finite element-based MIDAS CIVIL software is performed to study the behavior of deck continuity at highway level superstructure in integrated double decker bridge for the thermal effect, other secondary effects like creep, shrinkage and for live load forces. In this study, the structural parameters, boundary conditions are considered as per Indian Railway Standards, Indian Road Standards & other applicable Indian Standards, and the rail structure connectivity with deck for unballasted conditions are followed as per UIC 774-3R. This paper discusses the behavior of deck continuity in double decker integrated structure and based on the optimum force to the substructure, four span deck continuity is proposed in this double decker integrated viaduct with first level deck carrying road system and second level deck carrying metro system.

Published: November 2023

Auxin, as a vital phytohormone, is enriched in the vascular cambium, playing a crucial role in regulating wood formation in trees. Despite its significance, the molecular mechanisms underlying the influence of auxin on wood development remain elusive. In this study, we report a transcription factor, PLETHORA 5 (PLT5), whose expression was specifically activated by auxin signalling in the vascular cambium. PLT5 was found to regulate cell expansion and lignification of fibres in poplar. Genetic experiments confirmed the noncell-autonomous regulation of auxin signalling from the vascular cambium and revealed the necessity of PLT5 protein mobility to mediate this process. Remarkably, PLT5 proteins specifically inhibit the initiation of fibre cell wall thickening by directly repressing SND1 genes. This study unveils a sophisticated model wherein the auxin-PLT5 signalling cascade intricately regulates wood fibre development in poplar by fine-tuning the thickening of fibre cell walls.
A Comparison of cryoballoon and Radiofrequency ablation as redo procedure-ablation in Patients with recurrent Atrial fibrillation after cryoballoon-ablation
Authors: Schehab Wasim , schloemicher Markus , Kciku Gresa , Pradhan Snehasis , Trappe Hans-Joachim , Strauch Justus
Published: November 2023

Background:
A significant proportion of patients with recurrent atrial fibrillation (AF) require repeat radiofrequency (RFC) or cryoballoon (CB) ablation after the blanket period (90 days) following the initial cryoablation. However, little is known about the efficacy of pulmonary vein isolation using either of the technique as a redo procedure. Therefore, the present study aimed to analyze the electrophysiological characteristics of pulmonaary veins (PVs) during redo ablation procedures and clinical outcomes in patients undergoing CB-vs-RFC ablation as redo procedures.
Methods:
61 Patients with paroxysmal and persistent atrial fibrillation were retrospectively included in the analysis. The number and location of reconnected PVs, another arrhythmic drug before the reablation, structural heart disease and antiarrhythmic drugs were determined.
Results:
Before the redo procedure, paroxysmal atrial fibrillation was the predominant recurrent arrhythmia (60%). However,20 patients (70%) had paroxysmal atrial fibrillation in the RFC and 16 Patients (50%) in the CB group 29 Patients (47,5%) underwent a catheter ablation with radiofrequency, and 32 Patients (50,8%) underwent a catheter ablation with a cryoballoon. The Median of reablation occurred of 238 and 323 days (P= 0,0008). The Number of the reconnected PVs was 42 in the RFC group and was 99 in the CB group, which means the number of lesions applied during the redo Procedure was significantly greater in the CB cohort. The reconnection was driven by more reconnection in the left superior PV. After Reablation, there were no differences in the antiarrhythmic drug between the cohorts, but significantly more patients required amiodarone in the RFC Cohort.
Conclusion:
This analysis revealed an overall success rate of 70% in patients with recurrent atrial fibrillation who underwent a redo treatment using either radiofrequency or cryoballoon, implying equivalent performance effectiveness between both modalities.
Evidence for small-scale segmented fault rupture along the East Anatolian Fault during the Mw 7.8 2023 Kahramanmaras earthquake
Authors: Palo Mauro , Zollo Aldo
Published: November 2023

The rupture front of the first ∼25 s of the 2023 Mw 7.8 Kahramanmara¸s earthquake is tracked using the P-wave polarization vector vs time as measured at the dense three-component accelerometer network surrounding the slipping fault. We find a coherent increase of the spatially variable rupture velocity along portions of the earthquake fault zone where high coseismic slip has been previously mapped by kinematic source imaging studies. This is clearly detected in a domain of the Pazarcik segment of the East Anatolian Fault located at 70 km NE of the mainshock epicenter where the rupture velocity rises to super-shear values. This domain spatially matches the part of the Pazarcik segment where most micro-earthquakes nucleate in the inter-seismic phase and edges at north a nearly aseismic domain. We postulate the existence of velocity weakening subsegment on the Pazarcik fault sandwiched between velocity strengthening domains and/or mechanic barriers to the fault slipping.

Published: November 2023

In 2022, a genotype IV (GIV) strain of Japanese encephalitis virus caused an unprecedented and widespread outbreak of disease in pigs and humans in Australia. As no veterinary vaccines against JEV are approved in Australia and all current approved human and veterinary vaccines are derived from genotype (G) III JEV strains, we used the recently described insect-specific Binjari virus (BinJV) chimeric flavivirus vaccine technology to produce a JEV GIV vaccine candidate. Herein we describe the production of a chimeric virus displaying the structural prM and E proteins of a JEV GIV isolate obtained from a stillborn piglet (JEVNSW/22) in the genomic backbone of BinJV (BinJ/JEVNSW/22-prME). BinJ/JEVNSW/22-prME was shown to be antigenically indistinguishable from the JEVNSW/22 parental virus by KD analysis and a panel of JEV-reactive monoclonal antibodies in ELISA. BinJ/JEVNSW/22-prME replicated efficiently in C6/36 cells, reaching titres of 108 infectious units/mL - an important attribute for vaccine manufacture. As expected, BinJ/JEVNSW/22-prME failed to replicate in a variety of vertebrate cells lines. When used to immunise mice, the vaccine induced a potent virus neutralising response against JEVNSW/22 and to GII and GIII JEV strains. The BinJ/JEVNSW/22-prME vaccine provided complete protection against lethal challenge with JEVNSW/22, whilst also providing partial protection against viraemia and disease for the related Murray Valley encephalitis virus. Our results demonstrate that BinJ/JEVNSW/22-prME is a promising vaccine candidate against JEV.

Authors: Liu Naifei , Liang Shihao , Wang Shuangjie , Song Zhanping
Published: November 2023

The freezing damage of rock tunnels in cold region involves ice-water phase change and complicated interaction of moisture field, temperature field and stress field. Taking the fractured rock mass of cold region tunnels as research subject, the Thermo-Hydro-Mechanical (THM) coupling model of cold region tunnels was established based on the seepage mechanics, heat transfer theory, damage mechanics and equivalent continuum theory. This model could reflect the anisotropic properties of deformation, water migration and heat transfer caused by the initial fracture. The construction and operation processes of a rock tunnel in cold region were simulated, and results were compared with the measured value and predecessor’s achievements. It shows that proposed model could reflect the anisotropic property of surrounding rock and the simulated deformation and stress are not symmetrical. The results of this paper are much closer to the measured value. The insulating layer has a significant effect on the stress of the supporting structures. The maximum tension stress of the lining is 4.5 times as that without insulating layer, and the lining will be destroyed for the overlarge tension stress.
REGIS: Refining Generated Videos via Iterative Stylistic Redesigning
Authors: Abohwo Jason
Published: November 2023

In recent years, generative models have made impressive advancements towards realistic output; in particular, models working in the modalities of text and audio have reached a level of quality at which generated text or audio cannot be easily distinguished from real text or audio Despite these revolutionary advancements, the synthesis of realistic and temporally consistent videos is still in its inception. In this paper, we introduce a novel approach to the creation of realistic videos that focuses on improving the generated video in the latter steps of a video generation process. Specifically, we propose a framework for the iterative refinement of generated videos through repeated passes through a neural network trained to model the spatio-temporal dependencies found in real videos. Through our experiments, we demonstrate that our proposed approach significantly improves upon the generations of text-to-video models and achieves state-of-the-art results of the UCF-101 benchmark; removing the spatio-temporal artifacts and noise that make synthetic videos distinguishable from real videos. In addition, we discuss the ways in which one might augment this framework to achieve better performance.

The Simons Observatory (SO) experiment is a cosmic microwave background (CMB) experiment located in the Atacama Desert, Chile. The SO’s small aperture telescopes (SATs) consist of three telescopes designed for precise CMB polarimetry at large angular scales. Each SAT uses a cryogenic rotating half-wave plate (HWP) as a polarization modulator to mitigate atmospheric 1/f noise and other systematics. To realize efficient polarization modulation over the observation bands, we fabricated an achromatic HWP (AHWP) consisting of three sapphire plates with anti-reflection coatings. The AHWP is designed to have broadband modulation efficiency and transmittance. This paper reports on the design and the preliminary characterization of the AHWPs for SATs.
Investigating the Link Between Anxiety and Multiple Sclerosis: A Review
Authors: Mohammed Eiman M. A.
Published: November 2023

Background
Nearly one billion people worldwide have a mental disorder. During the last few years, the number of people suffering from psychological disorders such as depression and anxiety has increased by more than 25%. Just over 22% of multiple sclerosis (MS) patients experience anxiety. MS is an autoimmune disorder of the central nervous system (CNS) that is characterized by a complex interplay of factors, leading to inflammation, demyelination, and neurodegeneration. The disease strikes more people every year with no definitive aetiology. Many genetic, infectious, and environmental factors were confirmed as MS risk factors, but no psychological factors have been considered.
Objective
This review aims to explore the effect of anxiety on the manifestation of MS, the correlation between anxiety and MS symptomology, and possible connection points between anxiety and MS.
Method
A literature search was conducted in the NCBI PubMed database to investigate the impact of anxiety on MS symptomology and episodes, as well as any possible link between anxiety and MS. The search was conducted up to October 2022.
Results
Database searches retrieved a total of 1,607 articles for the phrase ‘multiple sclerosis and anxiety’ published from 1964 to 2022. Data were thoroughly reviewed to include only statistically significant associations. Several articles reported strong associations between anxiety and MS symptoms and episodes. Despite the lack of articles exploring the relationship between anxiety and MS, several pointed to the negative effect of anxiety on the immune system. The fact that MS is an autoimmune disorder of the CNS, and that anxiety dysregulates immunity, could indicate that anxiety has an effect on MS.
Prospective:
Further studies must be undertaken to understand the influence of anxiety on MS; meanwhile, psychological evaluation of MS patients is strongly recommended and needs to be incorporated into treatment plans.
A critical review of multicriteria decision analysis practices in planning of urban green spaces and nature-based solutions
Authors: Bousquet Morgane , Kuller Martijn , Lacroix Sandrine , Vanrolleghem Peter A.
Published: November 2023

Green spaces and nature-based solutions (NBS) are increasingly considered by land-use planning policies to respond to the multiple challenges related to sustainable development. The multiple benefits brought by NBS make the use of multicriteria decision analysis (MCDA) essential to optimally balance their use. MCDA offers a catalog of methods allowing to structure problems with multiple objectives and to help adopt the optimal solution. However, NBS planning is a recent discipline and research is still ongoing to make this practice more common. We carried out a critical literature review on MCDA-NBS tools and practices, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) method on the Web of Science database. We selected 124 papers on the subject between 2000 and 2022. We present a state-of-the-art MCDA approach for NBS and green space planning by looking at where these practices are applied, why and how this process is conducted, and who is involved in it. We found that studies are usually conducted in the global North on a single case study with the help of experts involved in the criteria weighting phase and the help of GIS MCDA tools often integrating a direct ranking method or the AHP method.
Numerical Study on Discrete Confinement of Circular RC Column Subjected to Eccentric Load
Authors: Yansiku Sandy I. , Piscesa Bambang , Suprobo Priyo
Published: November 2023

Background:

The performance of concrete-filled steel-tube (CFST) columns under axial compression is excellent. However, the steel-tube wall's instability due to insufficient outward restraint from the concrete made the steel tube lose its lateral support, thereby making it more susceptible to buckling.

Objective:

This study aims to propose and investigate a confinement mechanism that can remove the possibility of buckling of the steel tube by introducing gaps and pre-tension to prevent tube detachment from concrete. The investigation was carried out using both experimental tests and numerical simulation.

Methods:

The proposed confinement mechanism consists of thin steel sheets with gaps between them and is pre-tensioned in a staggered scheme. The performance of the proposed confinement mechanism is evaluated through experimental tests and numerical simulations using an in-house 3D-NLFEA package. The observed behaviors are the axial stress-strain, strength index, initial confining pressure, and ductility.

Results:

Experimental works found that the primary failure mode in the compression zone of the strengthened column was due to lateral expansion of concrete which may be attributed to strain localization, longitudinal tensile cracking, and severe concrete crushing. On the other hand, at the tensile region, pure tensile forces occurred, followed by crack opening displacement at the outer tensile fiber region. With the proposed confinement mechanism, the extreme failure event can be reduced. The axial capacity and ductility of the strengthened column were enhanced. The numerical model presented the initial confining pressure by the pre-tensioned steel sheet (a clamping mechanism), which successfully increased the axial load capacity of the slender reinforced concrete (RC) column and reduced the possibility of cover spalling.

Conclusion:

The proposed confinement mechanism to strengthen an RC column was found to successfully enhance the load-carrying capacity and ductility of a slender circular reinforced concrete column.
Nocardia Lymphadenitis and Encephalitis in Immunocompromised Patient: A Case Report
Authors: Pinzon Rizaldy Taslim , Primastuti Tillandsia Filli Folia
Published: November 2023

Background:

Nocardiosis-related HIV usually appears in immunocompromised patients, which is caused by Nocardia sp. Although a number of reports describe pulmonary forms of nocardiosis in HIV-positive patients, lymphadenitis and encephalitis due to this organism are rare entities. Our preliminary search has only found a few cases reported in the literature. Unless investigations like gram stain and culture for Nocardia are specifically done, the infection is often mistaken for tuberculosis. We have herein reported a case of Nocardia lymphadenitis and encephalitis in an HIV-positive patient.

Case Presentation:

A 33-year-old male presented fever, progressive weakness in the right side of the body, multiple lesions on the oral cavity, and left colli lesions. Physical examination found GCS as E4 M6 V uncounted, hypertonic and increased physiology reflexes on the right extremity without pathologic reflexes, meningeal signs, and all cranial nerves as normal. The laboratory test result was HIV-positive with CD4+ 7 cells/μL and Nocardia sp. on histopathology. A plain head computed tomography (CT) scan showed a hypodense lesion in the fronto-temporo-parieto-occipital sinistra region, and vasogenic edema. The patient was administered antiretroviral (ARV) therapy and antibiotics for nocardiosis lymphadenitis.

Conclusion:

A rare case of Nocardia lymphadenitis has been reported in this paper, and the physician must be aware of nocardiosis in HIV patients with neurological deficits.
Effect of ER: YAG Laser Treatment on the Bond Strength of Self-adhesive Resin Cements on Contaminated and Non-contaminated Dentin Surface
Authors: Rafeie Niyousha , Rashidi Marie , Chiniforush Nasim , Valizadeh Sara , Omrani Ladan Ranjbar
Published: November 2023

Background:

Nowadays, lasers are used to modify the surface of dentin and enamel and improve the surface bond with resin cement while contamination weakens this bond.

Objective:

This study aimed to evaluate the effect of different contamination types on the microshear bond strength (μSBS) of two self-adhesive resin cements to dentin with/without laser treatment.

Methods:

One-hundred and twenty molar teeth were prepared and randomly divided into three groups: blood, saliva, and control. In the blood group, blood was applied to the samples for 10 seconds; in the saliva group, saliva was applied to the samples for 10 seconds; and in the control group, distilled water was applied to the samples. Each group was further divided into two subgroups; in one, the Er: YAG laser was applied to samples for 5 seconds, and in the other, no laser treatment was performed. Next, TheraCem and Embrace WetBond cements were placed on each sample. μSBS was measured using a universal testing machine.

Results:

In Embrace WetBond, μSBS was not affected by contamination type regardless of laser treatment. In TheraCem, μSBS was not affected by contamination type when the laser was not used. In contrast, with laser treatment, blood contamination decreased μSBS compared to control and saliva. After laser treatment in the presence of blood, μSBS of Embrace WetBond was significantly higher than that of TheraCem, while without laser treatment, no significant difference was observed between the two cements.

Conclusion:

Dentin conditioning with an erbium laser can increase the cement bond strength to dentin if proper isolation is achievable. If proper isolation cannot be obtained, dentin conditioning with erbium laser followed by application of Embrace WetBond cement can increase the microshear bond strength of cement to dentin.

Published: November 2023

Background:

Clinicians often face a dilemma when determining the cause of a patient's tooth discolouration and how to treat it concurrently in the presence of trauma-induced external root cervical resorption.

Objective:

This case report describes the management of trauma-induced cervical resorption and discolouration of the maxillary central incisors with a four-year follow-up.

Case Report:

A 38-year-old gentleman requested that the shape and colour of his anterior teeth be restored. The patient had a history of a motorcycle accident 15 years ago, in 2003, that resulted in fractures in both maxillary central incisors. Clinical examination showed the presence of discoloured broken teeth 11 and 21, as well as a cervical defect in tooth 11 palatally. Upon radiographic examination, 11 and 21 were root canal treated, and there was cervical resorption related to 11. Treatment consisted of cervical resorption management, internal and external bleaching, and composite restoration of the maxillary central incisors.

After a four-year follow-up, this report demonstrated the successful management of a complicated case involving trauma induced resorption and discolouration. The patient expressed satisfaction with the conservative strategy that was taken to treat his discoloured teeth.

Conclusion:

This clinical report, with a long follow-up record, helps to provide dental practitioners with a conservative, minimally invasive, patient-centred treatment alternative for a complicated tooth discoloration case.

Published: November 2023

Context:

The behavior model for preventing HIV/AIDS transmission in lesbian, gay, bisexual, and transgender (LGBT) youth can contain HIV/AIDS information in this population.

Objective:

According to Planned Behavior Theory (PBT), human growth within different social environments may gain further information on various issues. This information can be the basis of their behavioral beliefs, social demands of essential others (normative beliefs), and obstacles that can prevent them from showing certain behaviors (control beliefs). These factors can influence intention and behavior. This study aims to develop a model for HIV/AIDS risk-related behavior among LGBT youth based on PBT.

Methods:

This was an observational study using a cross-sectional approach. The modeling used the Structural Equation Model (SEM) pathway through the AMOS 8.50 software application. The variables in this study are internal factors, such as religious obedience, knowledge, beliefs, intention, and risky behavior.

Participants:

This study occurred in Gorontalo Province with 200 LGBT youths with risky behaviors.

Results:

Risk behavior modeling results of LGBT youths in Gorontalo; Religious adherence affects risk behavior through intention. Overall, research results from the study using the PBT approach emphasize that religious obedience does not directly affect the behavioral variables but rather beliefs and intentions.

Conclusion:

HIV/AIDS prevention programs for LGBT youth should focus on religious activities.

Published: November 2023

Introduction:

Reinforced concrete beams are used in a wide range of applications. In addition, reducing the weight of the concrete used increases the advantages of the beams. The main objective of this work is to study the performance of structurally strengthened lightweight reinforced concrete beams with different techniques with or without exposure to fire under concentric load and the efficacy of the fire protection system.

Methods:

The experimental specimens included eight half-scale tested rectangle beams with typical dimensions of 300 mm depth, 1700 mm total length, 150 mm total width, 50 mm cover, and 1500 mm span. The density of the lightweight polystyrene foam concrete was 1820kg/m3. The main parameters were fire resistance, different types of strengthening material for lightweight concrete beams, shape of the ferrocement layer on the lightweight concrete surface, and ferrocement thickness.

Results:

The results were analyzed in terms of crack patterns, failure modes, load deflection, load-strain behavior, stiffness, ductility, deformability, and absorbed energy.

Conclusion:

From the analysis of the results, the strength of LWC beams increased the strength and stiffness of the tested beam, and the fire protection system was found effective in protecting CFRP limitation from deterioration. In a theoretical study, the conservatism degree for calculating the maximum allowable flexure force was evaluated according to the ECP203, ACI-318, and BS-8110 codes.
Ekspor Sampah Uni Eropa ke Indonesia sebagai Bentuk Eco-Imperialism
Authors:   University of Indonesia, Khairunnisa Meyfitha Dea
Published: November 2023

Environmental policy has become an important aspect of reviewing international relations environmental issues. The European Union is a regional institution that has been very active in international environmental cooperation. However, at the same time, the European Union is one of the largest waste exporters to countries in Asia, including Indonesia. Waste export is a free trade mechanism that allows developed countries to send waste to developing countries to be processed as industry materials. This then becomes contradictory to the commitment of the European Union in promoting environmentally friendly policies, and policies for the export of waste are considered as a form of ecoimperialism. This article discusses how the waste export policy by the European Union has become a form of ecological colonization for Indonesia as a waste recipient.

Skema Visa British National Overseas dan Diplomasi Migrasi Inggris dengan Tiongkok
Authors:   Universitas Brawijaya, Ayuningtyas Monica
Published: November 2023

ABSTRACT In June 2020 Chinese Government officially enacted the National Security Act in Hong Kong. The UK saw the act as a serious breach of the 1997 Sino-British Joint Declaration. In response, the UK issued a new visa scheme for British National (Overseas) holders. The new scheme provides Hong Kong residents holding BNO status with a residence permit of up to 5 years and permission to apply for British citizenship. This research will describe how the UK uses migration policy in correlation to diplomacy through this phenomenon. The concept to be used is migration diplomacy by looking at aspects of the definition, categories, and objectives of the new BNO visa scheme. As a result, this research finds that the UK uses migration policy as a tool of diplomacy with China by positioning itself as a receiving country. The implementation of migration diplomacy by the UK in the BNO visa scheme aims for economic gain, related to bilateral relations with China, and promoting Global Britain.

In the millennial era, our students are already infatuated with digital. Javanese language which is included in the local content of Junior High Schools, students are presented with local languages which have shifted a lot in usage. Students rarely use Javanese which is difficult in the form of pronunciation. The problems are (1) students in reading, writing and speaking Javanese do not understand and find it difficult to apply aspects of pronunciation and phonetics in their use. (2) the lack of interest of millennial students in preserving regional languages. (3) based on observations, today's students are lacking, mastering Javanese is called "ora njawani". And (4) the lack of teaching materials to attract students' interest, especially in the current trend, through digital. Teachers can use digital media Student Pocket Book Products which contain content from the creativity of students and teachers. In addition, students are used to using digital features. The solution to the problem of Servants is to train and assist teachers and students using digital-based learning methods and media and maintain culture. The Jombangan dictionary digital book product is used as a blended learning’s medium media. This book is equipped with a barcode that contains infographic content or Javanese Jombangan YouTube content that can trigger student motivation in applying Javanese. So that students can use digital dictionaries independently and innovatively. This method can help students and teachers learn Javanese pronunciation.

This study investigates the antagonistic behaviour of Alice –as someone who is in favour of extreme-right wing authority–, who initially conceals her support for the dominance of the extreme right-wing party that espouses white supremacy ideology in her interaction with Ousmane as someone who has affected by racism and discrimination. As film progresses, there is a change in her attitude from being concealed to being openly supportive of the ideology of the right-wing or even far-right party, which does not favour pluralism, immigrants, and non-white people, also known as xenophobia. Regarding Alice's behaviour, all of her speech acts will be analysed using Pragmatics-Sociolinguistics theory. It is hoped that by using Pragmatics-Sociolinguistics theory, the behavior and speech acts of the character Alice can be explained and analyzed.

A field experiment was conducted in clay-textured soil during the agricultural season 2021-2022 at Al-Muthanna Governorate, Al-Suwayr District - Albugrad region, longitude "5. 16' 36°31, and a latitude '0'. 52' 27 ° 45, to study the effect of biochar and perlite on the growth and yield of barley in clay soil. The experiment used a Randomized Block Design (RCBD) with two factors and three replicates. The biochar factor treatments included four levels of biochar at the level (0% B0, 0.5% B1, 1% B2, 1.5% B3). In comparison, the treatments of the second factor perlite included four levels. They are the addition of agricultural perlite at the level (0% P0, 0.5% P1, 1% P2, 1.5% P3). Mixing biochar with agricultural perlite for all treatments with soil to a depth of 30 cm. Barley (Hordeum vulgare L.) cultivar Iba 99 was planted on 1/11/2021. Crop service operations were carried out from adding chemical fertilizers, jungle control and irrigation until the end of the experiment and harvest on 9/9/2022. The results showed the superiority of the B3 biochar treatment (1.5% biochar) in improving most of the physical and chemical properties of the soil, plant height, number of branches and total yield, the superiority of the B2 biochar treatment (1% biochar) in recording the highest weight of 1000 grains, the treatment of perlite P1 (0.5% perlite) was superior in recording the highest weight of 1000 grains, the superiority of the B3P3 interaction treatment in recording the highest value of the number of branches in the plant. Keywords: Biochar, perlite, growth, yield, barley, clay soil.
Association among Helicobacter pylori (H. pylori) infection and vitamin D shortage, hemoglobin deficiency, dietary habits, and other
variations in children aged 6 to 18 years: cross-sectional investigation at an Iraqi children's hospital

Background: Several studies have shown a correlation between Helicobacter pylori
(H.pylori) and vitamin D, but considerable disagreement exists. The goal of this
study was to see if there was a relationship between vitamin D3 deficiency on the
one hand, dietary habits on the other hand, and Helicobacter pylori (H. pylori) infection in kids patients in a hospital in Iraq. Methods: In 2022, a cross-sectional
study was done on 1600 patients in a child hospital in Iraq. A structured questionnaire was used to collect information on socio-demographic and lifestyle variables,
and a short food frequency questionnaire was used to determine dietary patterns
(FFQ). After a blood sample from the vein was taken, the H. pylori status (positive
vs. negative) was identified. The stool and blood samples were all collected and
sent to the hematology, chemistry, and parasitology lab for examination. Logistical
multivariable to determine the relationship between socio-demographic, lifestyle,
nutritional, and other factors, regression used. With H.pylori infection, there are
several health-related issues to consider. In this sample, the prevalence of H. pylori
infection was 62.8%. The multivariable analysis revealed that the risk of H. pylori
infection was higher among those who did not follow healthy eating habits and
whose parents were uneducated. The study found that Vit.D3 deficiency increased
in girls more than in boys. H. pylori is associated with socio-demographic and clinical factors. More research is needed to determine the impact of diet on H. pylori
risk.

Effect of Partial Drip Irrigation Methods on Soil Moisture and Water Potential Distribution, Growth Characteristics and Yield of
Maize
Authors: Ahmed Saja M. , Masood Tareq K.
Published: November 2023

A field experiment was conducted during the autumn of 2021 at the Agricultural
Research Department station / Abu Ghraib to evaluate the soil moisture, water potential distribution, and growth factors of maize crops under alternating and constant partial drip irrigation methods. In the experiment, two irrigation systems were
used, surface drip irrigation (DI) and subsurface irrigation (SD); under each irrigation system, five irrigation methods were: conventional irrigation (CI), and 75 and
50% of the amount of water of CI of each of the alternating partial irrigation
APRI75 and APRI50 and the constant partial irrigation FPRI75 and FPRI50 respectively. The results showed that the water depth for conventional irrigation (C1)
was 658.3 and 579.4 mm for the DI and SD irrigation systems, respectively, and
the irrigation depth was reduced to 18% when applied APRI75 and FPRI75 and
37% when applied APRI50 and FPRI50 respectively. The moisture distribution
differed according to the irrigation method, and the SD provided a higher moisture
content and lower water potential due to the lower evaporation rate from the soil
surface. Also, the growth traits of maize varied according to the irrigation system
and its methods. The SD system was significantly superior in the grain yield of
maize with an increase of 5.4% compared with DI, and the alternating partial irrigation treatments were significantly superior to the constant partial irrigation.
