Authors: ERTURK Anıl , GOKCE Gulay , KENDER ERTURK Nergis
Published: August 2023

Objectives: Isthmocele is a hypoechoic area within the lower uterine segment myometrium, resulting from a discontinuation of the myometrium at the site of a previous cesarean scar. The aim of this study was to examine the influence of maternal cellular and inflammatory status prior to Cesarean Section (CS) on isthmocele formation.
Methods: This prospective observational study was conducted in a tertiary hospital and included women with a history of one previous CS. The inflammatory and cellular parameters were collected and ultrasonographic examinations were conducted in the 6th postpartum month and then analyzed. Logistic regression analysis was performed to identify potential factors influencing isthmocele formation.
Results: Of the 106 patients, 31 (29.2%) were diagnosed with isthmocele after one previous CS. There were no significant differences in terms of demographical variables between the groups. However, the duration of CS was significantly longer in the isthmocele group compared to the group without isthmocele (42.58 ± 8.77 vs. 38.42 ± 9.50 minutes, p = 0.03). The neutrophil-to-lymphocyte ratio (NLR) was higher and platelet-to-lymphocyte ratio (PLR) was lower in the isthmocele group (p < 0.001). Logistic regression analysis revealed that, NLR (OR [odds ratio]: 0.23, 95% CI [confidence interval]: 0.117- 0.473, p < 0.001) and PLR (OR: 1.05, 95% CI: 1.027-1.078, p < 0.001) were identified as independent predictors for isthmocele formation after planned CS.
Conclusion: Inflammatory markers, such as NLR and PLR, may contribute to the formation of isthmocele in women with a history of one previous CS, shedding light on the underlying pathophysiology.

Published: August 2023

Aim: The aim of this study was to examine the relationship between food literacy, health literacy, and healthy eating obsession in call center employees.
Material and Methods: The cross-sectional descriptive study was conducted with 545 participants working in a call center, of whom 68.1% (n=371) were female and 31.9% (n=174) were male. A questionnaire consisting of sociodemographic data form, and perceived food literacy, health literacy, and ORTO-R scales were applied to the participants.
Results: While 51.7% (n=282) of the participants had a normal body mass index, 41.7% (n=227) were overweight. Perceived food literacy (p=0.008) and ORTO-R (p=0.004) scores of female participants were higher than male participants, and those who were married had higher perceived food literacy scores than singles (p=0.003). Underweight individuals scored higher perceived food literacy than normal-weight individuals, and normal-weight individuals scored higher than overweight individuals (p=0.004). ORTO-R scores of the overweight group were higher than the other two groups and the difference was statistically significant (p<0.001). According to the regression analysis, health literacy decreased by 5.026 units for those who do not think they are eating healthy, and by 9.943 units for those who do not know how a healthy diet should be. Overweight participants exhibit more orthorexic eating behavior (p<0.001).
Conclusion: Effective and continuous training programs will be beneficial for call center employees who have inactive and sedentary working conditions due to their work, in order to determine their deficiencies or inadequacies in terms of gaining food literacy, health literacy, and healthy eating behavior.

Published: August 2023

The primary aim of Vietnam's new educational program is to enhance students' knowledge and skills through practical learning experiences, enabling them to tackle academic and real-world challenges. However, teachers in Dong Thap province face limitations in their professional competencies. Thus, this study aims to address these issues by examining different models for developing teachers' professional competencies. 1,116 participants participated in this study (258 managers and 868 teachers from high schools and preschools) who completed two questionnaires assessing their professional competence and the perceived importance of professional development. The findings reveal that teachers lack subject knowledge, interdisciplinary understanding   and skills in teaching design and assessment. Both school managers and teachers recognize the necessity of professional competence development. A three-step process for enhancing teachers' professional competence is proposed for implementing professional development activities based on these findings.

Authors: Fibularis Alma Pustika Kartikananda Retina , Wibawaty Halida
Published: August 2023

Introduction: Eales’ disease is an idiopathic inflammatory venous occlusion primarily affecting the peripheral retina. It commonly affects healthy young men aged 20-30 years, and 50-90% of patients develop bilateral involvement. Retinal changes include perivascular phlebitis, peripheral nonperfusion, and neovascularization. Case Presentation: We present a case of bilateral Eales’ disease; a 38-year-old man presented to our hospital with chief complaints of decreased and blurred vision, photopsia, and floaters in both eyes. The best corrected visual acuity (BCVA) at the initial presentation was hand movement in the right eye (RE) and 0.3 in the left eye (LE). The anterior segment and intraocular pressure (IOP) were normal. Funduscopy of both eyes highlighted dense vitreous opacity. In the RE, we found perivascular sheathing, perivascular exudates, dot and flame shape intraretinal hemorrhages, and focal occlusion of retinal vessels. In the LE, we found perivascular sheathing, perivascular exudates, and dot and flame shape intraretinal hemorrhages. Initial optical coherence tomography (OCT) results show central macular thinning. The disease resolved rapidly with an oral corticosteroid before the patient underwent pars plana vitrectomy. Conclusions: Eales’ disease can be treated with corticosteroids, anti-VEGF, laser photocoagulation, and pars plana vitrectomy. Even though the patient was planned for pars plana vitrectomy, we tried initial therapy using oral corticosteroids, which responded well to the patient’s chief complaints. OCT results also showed improvement in macular thickness after the third follow-up. Oral corticosteroid therapy shows good results in Eales’ disease treatment.

Published: August 2023

Introduction: Microbial keratitis is a corneal infection caused by microorganisms and is characterized by a profound corneal epithelial defect that infects the cornea and causes severe and progressive visual loss. In recent years, the incidence of microbial keratitis has increased. One of the critical risk factors for increasing this incidence is using contact lenses. As the number of contact lens users increases, the number of corneal ulcers associated with contact lenses also increases. Case Presentation: A 25-year-old man was admitted to the emergency department with a complaint of gradually blurry vision in his left eye four days after using contact lenses for overnight uses since the previous few days and did not routinely clean contact lenses or replace contact lens cleaning fluid. The visual acuity of the patient's left eye was hand movement with conjunctival and pericorneal injection in the conjunctiva and 6 x 7 mm stromal level infiltrate, blurred margin, and whitish color in the center of the cornea. After 28 days of treatment, an examination showed the patient's left eye improvement. Visual acuity was 3/60, conjunctival injection disappeared, corneal swelling significantly resolved, hypopyon disappeared, and ulcer completely re-epithelialized. Conclusions: Empirical therapy with broad-spectrum antibiotics and other adjunctive therapy has a good outcome in treating contact lens-related corneal ulcers.

Published: August 2023

Climate change is a major threat to the world. The cause for this global challenge is directly linked to greenhouse gas (GHG) emissions. In order to mitigate climate change, major policies such as reducing GHG emissions are required. Many countries have proposed carbon emission reduction targets at the national strategic level. A crucial issue in achieving the target is low-carbon energy transition, which requires a large amount of clean energy metals as supporting materials. This paper summarizes the latest research results of existing literature on the supply of clean energy metals in achieving the goal of carbon reduction, including the definitions, demand changes, supply capacity assessment, supply risk evolution, supply guarantee and policy system, etc . We point out that further research should be conducted in the following three directions in the future: firstly, strengthen research on the impact of trade and geopolitics on the supply of clean energy metals; secondly, further evaluate the effectiveness of minerals security policies in various countries; finally, broaden the analysis of the clean energy metals supply to encompass the entire industrial chain perspective.

Projective psychology of personality typology
Authors: Kornienko N. A.
Published: August 2023

Introduction. In recent years, graphical methods belonging to the class of projective methods have become very popular in psychological research, they enable a person to project reality himself and interpret it in his own way. Purpose setting. The expanding use of graphic methods and procedures has not yet led to the creation of works summarizing the experience of their use, to the formation of a general approach to the psychological analysis of different types of images. Methodology and methods of the study. The material for the analysis was the results of three series of experimental work, in which more than four thousand and more than three thousand drawings were obtained and analyzed according to the methods: constructive drawing of a person from geometric figures, psycho-geometrics by Susan Dellinger, Rorschach, etc. Results. The conducted analysis showed that the ratio of various elements in constructive drawings is not accidental, which allowed us to identify seven main types, which correspond to typological characteristics. The typological characteristic is based on the frequency of occurrence of a certain type among the respondents, as well as expert and subjective validity obtained as a result of a large number of conversations and observations during the survey. The article analyzes the long-term results of the study of students» personality typology using projective (graphic) methods. Conclusion. Based on a comparison of the results obtained using the graphical methods described by us, we came to the following conclusions. The use of graphic techniques significantly enriches the entire process of professional consultation, complements the individual characteristics of students who have chosen certain areas of professional activity. The study of individual psychological prerequisites for professional self-determination of a person using graphic methods has certain positive prospects: it allows a deeper analysis of the characteristics of an individual and develops more adequate recommendations for improving the effectiveness of professional self-determination of both youth and adults. Due to the projective nature of most graphic procedures, their results, as our research shows, are less susceptible to mind control, and this is a very important tool in favor of their application, since graphic diagnostic methods work «through a projection» onto the grid of psychological personality types, along with appropriate methods of the standard psychodiagnostic procedures for assessing personal qualities (MMPI, Cattell, Eysenck, etc.).
Phytocannabinoids Reduce Inﬂammation of Primed Macrophages and Enteric Glial Cells
Authors: Cohen Gal , Gover Ofer , Schwartz Betty
Published: August 2023

Inflammatory bowel diseases (IBD) includes Crohn's disease and ulcerative colitis, are idiopathic chronic relapsing inflammatory disorders of the intestinal tract. Different studies indicate that phytocanna-binoids, could play a possible role in the treatment of IBD by relieving the symptoms involved in the dis-ease. Phytocannabinoids act through the endocannabinoid system, which is distributed throughout the mammalian body in the cells of the immune system and in the intestinal cells. Our in vitro study analyzed the putative-anti-inflammatory effect of nine-selected pure cannabinoids in J774A1 macrophages cells and enteric glial cells (EGC’s) triggered to undergo inflammation with lipopolysaccharide (LPS). The an-ti-inflammatory effect of several phytocannabinoids was measured by their ability to reduce TNF tran-scription and translation in J774A1 macrophages and to diminish S100B and GFAP secretion and tran-scription in EGC’s. Our results demonstrate that THC at the lower concentrations tested exerted the most effective anti- inflammatory effect in both J774A1 macrophages and EGC’s compared to the other phy-tocannabinoids tested herein. We then performed RNA-seq analysis of EGC’s exposed to LPS in the presence or absence of THC or THC-COOH. Transcriptomic analysis of these EGC’s revealed 23 differ-entially expressed genes (DEG) compared to treatment with only LPS. Pretreatment with THC resulted in 26 DEG and pretreatment with THC-COOH resulted in 25 DEG. To evaluate which biological pathways were affected by the different phytocannabinoid treatments we used the Ingenuity platform. We show that THC treatment affected the mTOR and RAR signaling pathway while THC-COOH affected mainly the IL6 signaling pathway.
Does SARS-CoV-2 induce IgG4 synthesis to evade the immune system?
Authors: Rubio-Casillas Alberto , Redwan Elrashdy M. , Uversky Vladimir N.
Published: August 2023

SARS-CoV-2, the virus that causes theCOVID-19 disease, has been demonstrated to cause immune suppression in certain individuals. This can manifest as a reduced ability for the host's immune system to effectively control the infection. Studies have reported that patients with COVID-19 can exhibit a decline in white blood cell counts, including natural killer cells and T cells, which are integral components of the immune system's response to viral pathogens. These cells play critical roles in the immune response to viral infections, and their depletion can make it harder for the body to mount an effective defense against the virus. Additionally, the virus can also directly infect immune cells, further compromising their ability to function. Some individuals with severe COVID-19 pneumonia may develop a "cytokine storm," an overactive immune response that may result in tissue damage and organ malfunction. The underlying mechanisms of immune suppression in SARS-CoV-2 are not entirely comprehended at this time, and ongoing research is being conducted to gain a more comprehensive understanding. Research has shown that severe SARS-CoV-2 infection promotes the synthesis of IgG4 antibodies. In this work, we propose the hypothesis that the IgG4 antibody produced by B cells in response to infection by SARS-CoV2 generates immunological tolerance that prevents its elimination, and leads to persistence and chronic infection. In sum, we believe that this constitutes another immune evasion mechanism that bears striking similarities to that developed by cancer cells to evade immune surveillance.

Published: August 2023

As the need to minimize environmental impact continues to rise, it is essential to incorporate, advance, and adopt renewable energy sources and materials to attain climate neutrality. It is established that economic growth is built upon infrastructure where cement industry plays a crucial role. However, it is also known that this industry is actively looking for ways to transition towards low-carbon practices to encourage sustainable and environmentally conscious practices. To this end, the use of refused derived fuels to substitute fossil fuels is very appealing, as these present the potential to lower the clinker production costs and CO2 emissions. Bearing this in mind, the primary objective of this work is to gain insights of the combustion behavior in an industrial rotary kiln, studying real-life scenarios and assessing the potential of substituting alternative fuels for fossil fuels to reduce CO2 emissions. A 3D CFD turbulent combustion model was formulated in Ansys® considering a Pillard NOVAFLAM® burner, where refused derived and petcoke fuels were used and different secondary air mass flows were considered. From the obtained results it was possible to conclude that the outcome of the combustion process is greatly influenced by the fuel-to-air ratio. Increasing the secondary air mass flow promotes the occurrence of a complete and efficient combustion process, leading to an enhanced fuel conversion and decreased formation of pollutants as CO, soot, and unburnt hydrocarbons.

Published: August 2023

The rapid, sensitive, and selective detection of pathogenic bacteria is of utmost importance in ensuring food safety and preventing the spread of infectious diseases. Here, we present a novel, reusable, and cost-effective impedimetric sensor based on a dual bacteria-imprinted polymer (DBIP) for the specific detection of Escherichia coli O157:H7 and Staphylococcus aureus. The DBIP sensor stands out with its remarkably short fabrication time of just 20 minutes, achieved through the efficient electro-polymerization of o-phenylenediamine monomer in the presence of dual bacterial templates, followed by in-situ template removal. The key structural feature of the DBIP sensor lies in the cavity-free imprinting sites, indicative of a thin layer of bacterial surface imprinting. This facilitates rapid rebinding of the target bacteria within a mere 15 minutes, while the sensing interface regenerates in just 10 minutes, enhancing the sensor's overall efficiency. A notable advantage of the DBIP sensor is its exceptional selectivity, capable of distinguishing the target bacteria from closely related bacterial strains, including different serotypes. Moreover, the sensor exhibits high sensitivity, showcasing a low detection limit of approximately 9 CFU mL-1. The sensor's reusability further enhances its cost-effectiveness, reducing the need for frequent sensor replacements. The practicality of the DBIP sensor was demonstrated in the analysis of real apple juice samples, yielding good recoveries. The integration of quick fabrication, high selectivity, rapid response, sensitivity, and reusability makes the DBIP sensor a promising solution for monitoring pathogenic bacteria, playing a crucial role in ensuring food safety and safeguarding public health.

Published: August 2023

In this paper, we propose a pre-configured error pattern ordered statistics decoding (PEPOSD) algorithm and discuss its application to short cyclic redundancy check (CRC)-polar codes. Unlike the traditional OSD that changes the most reliable independent symbols, we regard the decoding process as testing the error patterns, like guessing random additive noise decoding (GRAND). Also, the pre-configurator referred from ordered reliability bits (ORB) GRAND can better control the range and testing order of EPs. Offline-online structure can accelerate the decoding process. Additionally, we also introduce two orders to optimize the search order for testing EPs. Compared with CRC-aided OSD and list decoding, PEPOSD can achieve a better trade-off between accuracy and complexity.

Medical Assistance in Dying (MAiD): Human and Humanity in The Study of Fiqh Maqașid
Authors: Aibak Kutbuddin
Published: August 2023

This study aimed to formulate the construction of fiqh maqașid as a standardization of the concept of humanity in Medical Assistance in Dying (MAiD). This study contributes to actualizing fiqh maqașid as a standardization of values in solving humanitarian problems. This is based on the phenomenon of MAiD, which is considered controversial in the eyes of social religion and state law as in the concept of Islamic law (fiqh), which sees that the protection and realization of human existence and humanity are essential values in the study of Islamic law (fiqh). This argumentation must be elaborated in depth regarding interests and benefit elements in the MAiD phenomenon. The stages of the realization of benefits in the context of the approach to Islamic law (fiqh) are one of the representations and forms of elasticity in the study of the objectives of Islamic law (maqașid al-sharia). The relevance of maqașid shari'ah studies as a form of maqașid fiqh approach is considered to carry urgency in determining aspects of benefit in the MAiD phenomenon and representing maqașid fiqh in realizing human protection and humanity. This study uses literature research with data from various phenomena and regulations on MAiD, which are presented descriptively and then critically analyzed through the fiqh maqașid approach. This study found that the realization of the MAiD program through euthanasia has implications for the non-realization of the essential values of maqașid shari'ah in fiqh maqașid. This study confirms that fiqh maqașid has an orientation towards solving human problems based on humanity
Green’s function in general relativity
Authors: Kurihara Yoshimasa
Published: August 2023

This report provides Green’s functions (classical propagators) of gravitational fields of vierbein and spin-connection in general relativity. The existence of Green’s function of the Laplace operator in curved space with an indefinite metric is ensured owing to the Hodge harmonic analysis. The analyticity of Green’s function is naturally determined intrinsically, keeping a causality. This report proposed a novel definition of the momentum space in curved space-time and the linearisation of the Einstein equation as a free field consistent with that for the Yang–Mills gauge field. The proposed linearisation does not utilize the weak-field approximation; thus, the method applies to highly caved space-time. We gave two examples of Green’s function of gravitational fields, the plane wave solution and the Schwarzschild solution. PACS numbers: 03.65.Sq,04.60.Bc,04.62.+v

The activated sludge reactor designed in this research includes a cube-shaped tank made of glass with a volume of 5 L and the volume of the sedimentation pond was considered to be 5 L. The design of experiments using the method of one variable in each step. The effect of different parameters and concentrations of variables (inoculum concentration (0.1, 0.15 and 0.2 g.L− 1), ammonium sulfate concentration (0.1, 0.3 and 0.5 g.L− 1) and sodium phosphate ( 0.1, 0.3 and 0.5 g.L− 1) are measured separately on the amount of wastewater treatment. Wastewater treatment tests are investigated in a period of 14 days, and biological treatment of wastewater (BOD) and total organic carbon (TOC) are reduced by 71.27 and 48.98%, respectively. The results show that with the reduction of total dissolved solid (TDS), the electrical conductivity (EC) of water decreases by 48.58%. During this period, the concentration of H2S, NH3, CH4, and CO2 gases in the effluent has shown a decreasing trend, which has decreased by 30.08, 60.25, 71.42, and 80.95%, respectively.
A preliminary investigation on the operational efficiency of centrifugal pumps operating in single-branch, single-pump systems
Authors: Pellegrini Claudio de Castro , Pedrera-Yanes Jacqueline , Llanes-Santiago Orestes , Vilalta-Alonso Guillermo
Published: August 2023

Pumping systems are among the most energy-consuming applications, making its efficient operation a matter of great relevance. In recent years, efforts to improve the efficiency of these systems have followed two approaches. The first involves the design and development of new efficient pump models, in studies primarily based on the internal flow behaviour and impeller geometrical parameters. This approach, albeit useful, does not consider whether these efficient pump models have been correctly selected. The second approach addresses the energy-saving potential achievable through the pumping system itself, including the proper pump selection, which is a research area that still offers opportunities for improvement. The primary objective of this work is to create a methodology to identify whether a pump has been efficiently selected for a given hydraulic system. To achieve this, the two main criteria currently used for evaluating the efficient selection of pumps are discussed: the POR-Q and the POR-η. The results demonstrate that the proposed methodology correctly identifies high-efficiency pumps for operating in a given system. It is shown that the flow rate interval where the pump can operate with high efficiency, as determined by the POR-η criterion, is wider than the interval obtained using the POR-Q criterion. This expansion in the available range of pump operation using the POR-η criterion allows for greater availability of pumps that meet the system requirements and respond well to energy-saving strategies. This finding enables a wider choice of pumps, thereby facilitating the decision-making process.

Wallachian expansion brought to the Carpathian Mountains a system of shepherd economy - farming, production of Wallachian cheeses, animals adapted to life in difficult mountain conditions - mainly sheep of the Cakiel breed group. Mountain sheep's milk is used to produce traditional cheeses: bundz, bryndza podhalańska, oscypek, redykołka - on the Polish side and Slovenská bryndza, Slovenská parenica, Slovenský oštiepok, Ovčí hrudkový syr salašnícky - on the Slovak side. From sheep meat are made sausages. These cheeses and sausages are salted and then traditionally smoked with warm smoke. The source of heat and smoke is hard wood with appropriate humidity, burned in the hearth located in the shepherd's hut, over which the cheeses are placed under the roof. Among several hundred smoke components, there are also polycyclic aromatic hydrocarbons, which, on the one hand, give the smoked product its taste and aroma, and on the other hand have carcinogenic and mutagenic properties. Sausages and cheeses from Poland and Slovakia, made from milk and meat of native sheep breeds, preserved by traditional smoking, were analyzed for polycyclic aromatic hydrocarbons content. The analyzed cheeses were characterized by a trace or low content of benzo[a]pyrene and the sum of benzo(a)pyrene, benzo(a)anthracene, benzo(b)fluoranthene and chrysene. In cheeses from outer Eastern Carpathians subprovince (Bieszczady) the high content of naphthalene, acenaphthylene, fluorene and phenanthrene is noteworthy. Polish lamb sausages were characterized by a higher content of benzo(a)pyrene and the sum of benzo(a)pyrene, benzo(a)anthracene, benzo(b)fluoranthene and chrysene. The differences result from the method of smoking (warm or cold in the south of the Carpathians - hot in the north) and the type of wood used for smoking.

The newly developed Z-Scheme Ni3V2O8/AgI visible light photocatalytic heterojunction composite system was fabricated using wet chemical technique with different weight percentages 10, 20, and 30% of Ni3V2O8 for the destruction of (RhB) Rhodamine-B. The purely isolated photocatalyst was further investigated through XRD, UV-vis DRS, TEM, FT-IR, PL, SEM, HRTEM, EDS, and photocurrent measurements. The Ni3V2O8/AgI nanocomposite degraded 82% of RhB with a higher reaction rate coefficient value of 0.0603 min–1 than the other synthesized photocatalysts. The results showed that Z-Scheme heterojunction formation has improved the partition and migration of charged particles leading to intensification in photocatalytic activity when compared to individual photocatalysts. The optimized 20% of Ni3V2O8 nanocomposite was reused three times without any change in photocatalytic performance, which confirmed the stability of the optimized nanocomposite photocatalyst Ni3V2O8/AgI. The outcomes of the radical trapping experiments suggested that radicals •OH and O2•− play a part in RhB degradation. Based on this, a visible light photocatalytic heterogeneous Z-Scheme mechanism is proposed. As a result, the newly fabricated Z-Scheme heterojunction Ni3V2O8/AgI photocatalyst could be a robust material for treating RhB water.

Published: August 2023

Background: Reindeer herding in Norway is based on traditional Sámi pastoralism with the animals free ranging throughout the year. The animals move over large areas in varying terrain and often in challenging weather conditions. Winter crises, such as difficult grazing conditions caused by icing or large amount of snow, are survival bottlenecks for reindeer. Calves are especially vulnerable, and many may die from starvation during winter crises. Predation and starvation are the predominant narrative to explain losses, however, carcasses are difficult to find and often little remains after scavenging and decay. Documentation of the causes of death is therefore scarce.
Results: In this study, we investigated the cause of reindeer mortality in Troms and Finnmark, Nordland and Trøndelag during 2017-2019. Necropsies (n=125) and organ investigation (n=13) were performed to document cause of death. Body condition was evaluated using visual fat score and bone marrow fat index. A wide range of causes of death was detected. The diagnosis were categorized into the following main diagnostic categories: predation (n=40), emaciation (n=35), infectious disease (n=20), trauma (n=11), feeding related disease (n=5), neoplasia (4), others (n=6) and unknown (n=17). Co-morbidities were seen in a number of diagnoses (n=16).
Reindeer herders are entitled to economic compensation for reindeer killed by endangered predators, but a lack of documentation leads to a gap between the amount of compensation requested and what is awarded. An important finding of our study was that predators killed animals in good as well as poor condition during winter. Emaciation was shown to also be associated with infectious diseases, and not only attributable to winter grazing conditions.
Conclusions: This study highlights the importance of examining dead reindeer to gain knowledge about why they die on winter pasture. The work presented herein also shows the feasibility and value of increased documentation of reindeer losses during winter.

xIn this study, the influence of the process parameters, traverse and rotational speeds, of dissimilar friction stir welded joints of AA2024-O and AA6061-O aluminum alloys on the corrosion resistance was evaluated. Potentiodynamic tests using a 3.5% NaCl solution obtained open circuit potential curves and polarization curves showing the corrosion behavior for the different welding parameters. These data were correlated with those obtained by mechanical tests (microhardness, tensile, and fracture analysis) and microstructure analysis by optical microscopy and scanning electron microscopy. It was observed that the combined effect of the parameters influenced the variation of corrosion resistance. This was mainly evidenced by the improvement in corrosion resistance at 1200rpm − 65mm · min−1 which was related to the recrystallization of the grain size and the heat input presented. Corrosive attacks on the welded joints showed greater affectations in the presence of base material 1 (AA6061-O) with greater metallic dissolution. The attacks mentioned above were presented in different forms, such as pitting, localized, and selective, and were observed by scanning electron microscopy. Finally, in corrosive and mechanical terms, the best performing condition was 1200rpm − 65mm · min−1 compared to the low parameter 840rpm − 45mm · min−1 .
Quantum Confinement Detection using a Coupled Schrödinger System
Authors: Li Chun
Published: August 2023

Machine learning techniques have provided valuable insights into understanding the fundamental principles of physics. Recent studies have demonstrated the ability of deep neural networks (DNNs) to learn a wide range of differential equations (DEs) and classical Hamiltonian mechanics systems. This has led to the emergence of solving the inverse problem associated with partial differential equations using DNNs. In this paper, we propose a novel method for detecting quantum confinement by numerically solving the Schr¨odinger system on manifolds with nonlinear coupling. Our method exhibits remarkable performance in identifying various quantum phenomena. Moreover, our research introduces a promising approach for principled modeling and prediction in quantum processes. By combining deep learning with traditional models, our hybrid model leverages the strengths of both approaches, enhancing computational efficiency and enabling meaningful predictions for complex quantum physical processes. The integration of multiple deep learning principles with quantum physics enables effective handling of large datasets and addresses inverse challenges related to intricate dynamical systems and physical phenomena.

Published: August 2023

Background and Aims
The rhizosphere environment regulated by root secretory activity and rhizosphere microbial interactions plays an essential role in resisting soil-borne diseases, while the host species is an important factor that affects the composition of root exudates and rhizosphere microbiomes. However, few studies have been done on the characteristics of root exudates and bacterial communities in terms of composition, diversity, and functional potential when host plants of different species are subjected to the same disease.
Methods
In this study, we examined the rhizosphere soil bacteria and root exudates of both healthy and diseased tomatoes and peppers employing metabolomics and amplicon techniques.
Results
Our findings indicated that variations existed in both root exudates and the bacterial community among different host species and health states. The diversities of both rhizosphere metabolites and bacterial communities were significantly reduced in different diseased plants. Although pepper and tomato resisted the invasion of Ralstonia by recruiting different potentially beneficial bacteria, their rhizosphere bacterial communities had the same functional potential. In contrast with diseased rhizosphere soil, healthy rhizosphere soil had many more functional pathways associated with disease suppression and plant growth.
Conclusions
This study highlighted the crucial role of host plants in shaping the rhizosphere environment and revealed the variation characteristics of root exudes and rhizosphere bacteria of different host plants induced by the same disease.

We here present a case of a fully healthy woman who underwent bimaxillary orthognathic surgery and experienced multiple complications both peri- and post-operatively. We also present the result after restorative surgery and endodontic and prosthodontic treatment resulting in a successful rehabilitation.
Efficacy of N-acetylcysteine plus pirfenidone in the treatment of idiopathic pulmonary fibrosis：a systematic review and meta-analysis
Authors: Zhang Xiu-Li , Cao Ying , Zheng Bo
Published: August 2023

Background
Numerous studies have demonstrated the potential of pirfenidone to enhance the prognosis of patients afflicted with idiopathic pulmonary fibrosis (IPF). Although N-acetylcysteine (NAC) is utilized as an antioxidant in IPF treatment, the combination of NAC and pirfenidone has produced inconsistent outcomes in certain studies. To assess the clinical effectiveness and safety of NAC plus pirfenidone (designated as the treatment group) versus pirfenidone monotherapy (designated as the control group), we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs).
Methods
RCTs of NAC plus pirfenidone were reviewed searching from databases and networks of unpublished and published studies in any language. Using pair-wise meta-analysis, changes in pulmonary function test (PFT) parameters and safety were evaluated .
Results
Two independent reviewers selected and obtained data from 5 RCTs (n = 398), comprising 1 study from Japan, 1 from Europe, and 3 from China. Based on changes in forced vital capacity (ΔFVC), changes in forced vital capacity percent predicted (ΔFVC%), changes in 6-minute walking test distance (Δ6MWT), and changes in percentage of predicted carbon monoxide diffusing capacity (ΔDLco%), the two groups were found to be comparable in terms of clinical efficacy. Both groups demonstrated similar and favorable safety profiles with respect to at least one side effect, severe side effects, gastrointestinal effects, and skin effects and mortality rates.
Conclusion
Based on this systematic review and meta-analysis, NAC plus pirfenidone did not
