Authors: Fu Fang , Yan Weiting , Yu Xinbei
Published: March 2023

Background
Fear of falling (FOF), regarded as one of the major long-term detrimental outcomes, is a common psychological issue that should not be neglected in elderly people with previous falling experience. This study intends to explore the confrontation of FOF among the elderly patients hospitalized due to falls.
Methods
Semi-structured in-depth interviews were performed with 21 elderly patients hospitalized in trauma surgery department wards due to falls, ranging in age from 61 to 83 years old (average 70.67 years)in the Orthopaedics Department of the hospital. Later, thematic analysis was performed to analyse the data obtained from the patient interviews.
Results
The results of this study proved that three types of coping strategies were developed by hospitalized older adults: primary confrontation, in terms of explaining the reason of falls by attributing it to inevitable Consequence of Ageing as well as accidental Events; secondary confrontation of fear including self-consolation, downstairs comparison and distraction from fear, as well as confronting and reflecting fear; and tertiary confrontation of the consequences of falling such as active rehabilitation, food therapy, seeking emotional support, use of assistive devices and environment modification.
Conclusion
The study highlighted the importance of taking preventive measure to avoid FOF. Moreover, a variety of cognitive coping strategies could be explored with hospitalized older adults to deal with the emotion of fear. The potential consequences of FOF can be dealt with by provide trainings in physical exercises and lectures containing nutrition information,etc.

Published: March 2023

Background: Communication of information about risk of type 2 diabetes (T2D) alone has not been associated with changes in habitual behaviors among individuals of European ancestry. In contrast, the use of wearable devices that monitor physical activity (PA) has been associated with changes in behavior in some studies. It is uncertain whether risk communication might enhance the effects of wearable devices. We aim to assess the effects on wearable-device-measured PA of communicating genetic risk for T2D alone or in combination with goal setting and activity prompts from a wearable device among overweight or obese East Asians.
Methods: In a parallel group, randomized controlled trial, a total of 355 overweight or obese East Asian individuals aged 40-60 years will be allocated into one of three groups: 1 control and 2 intervention groups. Blood samples will be used for estimation of T2D genetic risk and analysis of metabolic risk markers. Genetic risk of T2D will be estimated based on 113 SNPs associated with T2D among East Asians using an established method. All three groups will receive a Fitbit device. Both intervention groups will be given T2D genetic risk estimates along with lifestyle advice, but one of the intervention groups will additionally use Fitbit’s step-goal setting and prompt functions. Questionnaires and physical measurements will be administered at baseline, immediately after intervention delivery, and 6 and 12-month post-intervention following standard operating procedures. The primary outcome is time spent in moderate-to-vigorous PA measured through the Fitbit. Secondary outcomes include other parameters of wearable-device-measured PA, sedentary time, and sleep, body mass index, systolic and diastolic blood pressure, five intermediate metabolic risk markers, hand grip strength, self-reported PA, self-reported fruit and vegetable consumption and smoking status, and a list of psychological variables.
Discussion: This study will be the first randomized controlled trial using the combination of communication of T2D genetic risk with standard functions of wearable devices in any population. Findings will inform strategies to prevent T2D through lifestyle modification.

Authors: DEBELE ABU DUGUMA , Demeke Sinknesh , Bekele Tadele , Malimo Markos
Published: March 2023

Plastic waste poses serious environmental problems as it is non-biodegradable and consists of several toxic chemicals that can pollute the environment. The use of this waste as a substitute material is gaining interest due to its environmental friendliness. Therefore, the aim of this study was to develop and characterize paver tiles from sand and waste plastics. First, waste plastic is collected, identified, grinded, and melted at temperature of 170°C. The sample sand was sieved to size of less than 0.75mm and mixed with plastic in specified proportion, then molded. Paving tiles were developed using hydraulic press with process parameters of plastic percentage from 10% to 40%, pressure from 1MPa to 5MPa and pressing time from 2 to 8minutes. Individual and interaction effects of 3 process parameters on physico-mechanical properties like water absorption(WA), flexural strength(FS) and compressive strength(CS) were investigated and analyzed using BBD and Design -Expert13 software with p-values of 5%. The result showed that the optimum point was obtained at 25% of waste plastic, time of 5minutes and pressure of 3MPa, resulting in maximum FS of 3.689MPa and CS of 4.141MPa, and overall average WA of Paver was 0.322%. Therefore, the developed tiles have better WA, FS and CS that meet the desired standard. From this finding, it can be concluded that reusing LDPE waste plastic with sand in the production of tiles is possible, and used for various outdoor applications. Therefore, making pavement tiles by reusing waste plastic is a promising option to protect our environment from pollution.

Background:Mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) is a rare multisystem mitochondrial cytopathy that is highly heterogeneous in severity and clinical presentation mostly caused by diverse mutations in the mitochondrial DNA. Clinical spectrum of MELAS is broadening as atypical presentations and more knowledge are gathering from this syndrome. There is no specific known treatment for the progressive disease however metabolic cocktail have been used to improve ATP production.Case presentation: This report documents the case of a 37 year old Iranian woman diagnosed with MELAS. Her clinical manifestations include recurrent episodes of stroke-like events, focal seizures and elevated serum and CSF lactate. Mitochondrial DNA analysis (mtDNA) was positive for a very rare pathogen point mutation (mtDNA; m.3243A>G) in the MT-ND5 gene with a heteroplasmy level of 8.2%.Conclusion:The clinical spectrum of MELAS is broadening as its atypical presentations make a diagnostic challenge that may lead to decades of delay in diagnosis. The number of molecular causes of MELAS and Leigh syndrome (LS) has increased steadily.

Published: March 2023

Background
Myeloid or lymphoid progenitors in the bone marrow can develop into leukemia, which is clonal cancer. Acute myeloid leukemia (AML) developed as a result of somatic mutations in the precursor cells of the myeloid lineage along with transcriptome dysregulation of bone marrow infiltration, which resulted in the generation of immature myeloid cells (blasts) and disruption of normal hematopoiesis. Current research has demonstrated the metastasis potential of a certain subset of microRNAs. As a result, miRNA downregulation at the transcriptional level can reduce the possibility of metastasis. The purpose of this work is to analyze miRNA precursor targeting utilizing the CRISPR-C2c2 (Cas13a) method.
Results
crRNAs designed for miR-301b and miR-21 has a very high structural similarity with binding energy to the state observed in the normal condition.
Conclusion
Sequence-based evaluation of crRNAs intended for RNA-level editing is insufficient; simulation and molecular docking investigations should also be carried out for improved accuracy.
COVID-19 and Mental Health in China: Effects of Personality and Demographics
Authors: Zhang Xiao , Battisti Michele , Proto Eugenio
Published: March 2023

China was the first country affected by the COVID-19 virus and it reacted strongly in the first months of 2020. We present new evidence on the deterioration in mental health in China between 2018 and 2020. Using two waves of the China Family Panel Studies (CFPS) we can follow the same individuals pre and during the pandemic periods. We find clear evidence of a moderate level of mental health deterioration between 2018 and 2020. The prevalence of severe cases of depression, measured using an eight-item version of the common CES-D scale, increased from 6.33% in 2018 to 7.54% in 2020; quantifiable as around a 19% increase. This deterioration is higher for individuals who are subject to strict lockdowns, about 0.3 symptoms more on average, and it is stronger among those who already reported symptoms of depression in the 2018 wave of data. The effects we find are larger for individuals with more open personalities: one standard deviation of the Openness trait corresponds to 0.05 more symptoms, while more Neurotic individuals are rather surprisingly less affected. Younger cohorts and individuals with lower levels of education are more affected. Males seem slightly more affected than females, although this difference is statistically non-significant.

Published: March 2023

This paper is the first to integrate the two scientific paradigms of the negative feedback dynamics mechanism of El Niño–Southern Oscillation (ENSO) and deep learning methods, and systematically studies the prediction method of key regional variables of ENSO. This paper mainly performed two activities: first, two physics-informed neural network methods are proposed to solve the ordinary differential equations (ODEs) of ENSO negative feedback theory, including classical physics-informed neural networks (PINNs) and variant-physics-informed Long Short-Term Memory (PILSTM) neural networks, and the novel defined physics-informed neural network loss function weights are optimized and balanced. Second, only 780 natural month-scale small datasets in the Coupled Model Intercomparison Project Phase 6 (CMIP6) model are used to improve the accuracy of correlative skills, and solve the problem of obvious decline in medium- and long-term correlative skills in the current air–ocean coupled dynamic prediction model. The results show that the research paradigms of the two physics-informed neural networks are an effective and complementary method in dealing with medium- and long-term prediction problems. Moreover, the PILSTM model based on recharge–discharge oscillator theory performed the best, and were better than the traditional delayed oscillator theory numerical operator method and the recharge–discharge oscillator theory numerical operator method. Meanwhile, the proposed method solved the delay problem in the recharge–discharge oscillator theory, indicating that the physics-informed neural networks learned the negative feedback dynamics mechanism of ENSO well, and effectively complemented the existing ENSO oscillator theory through the features learned from the training data, which help us to further comprehend the complex mechanism of ENSO events.
Effects of Carbon Policies on Demand Pricing of Forest Carbon Sequestration: A Review of High-Carbon Emission Enterprises in China
Authors: Yang Hong , Long Fei , Zhu Zhen , Pan Rui , Wang Danting , Yang Jun , Shen Yueqin
Published: March 2023

This study aimed to promote the reasonable pricing of forest carbon sinks and the development of the carbon market. In this study, we utilized four carbon emission-intensive enterprises in the thermal power, steel and chemical industries in Shanghai, Beijing, Guangdong, and Hubei provinces. Based on the marginal carbon emission reduction costs of the sample enterprises, the Rubinstein game model was used to calculate the demand price of forest carbon sinks of the sample enterprises; moreover, the cloud model was used to simulate the impact of policy changes on them. This showed that the demand price of forest carbon sinks for enterprises in different regions and industries is different and there are great differences under different policy scenarios. Notably, the proportion of carbon offset allowed by the government and the amount of carbon subsidies have a positive impact on the demand price of forest carbon sinks; contrastingly, the rate of carbon tax collection has a negative impact. Among them, the allowable offset ratio significantly influences it. We suggest adopting differentiated emission reduction policies, increasing the proportion of forest carbon sequestration offset, and transitioning from a single policy to a diversified comprehensive policy.

Published: March 2023

Background: Rituximab(R) added to chemotherapy(CT) prolongs survival among pediatric Burkitt’s lymphoma(BL). Data on its side effect in pediatric patients are limited. We aim to explore the therapeutic effect of different doses of R on children with BL in high-risk group and whether there is any difference in the level of immunoglobulin after treatment.
Methods: We retrospectively summarize clinical data with high risk group BL treated in Beijing Children’s Hospital(BCH), baseline characteristics, treatment outcomes and serum immunoglobulin (Ig) level in different time point (before CT, end of CT, 6 months after CT, 12 months after CT)were collected. We compared the efficacy of CT combined with different doses of R and the difference of immunoglobulin level after treatment. At the same time, monitor whether the children have repeated severe infection and hepatitis B virus reactivation after treatment in the study period.
Results: (1)baseline characteristics: 300 high risk group BL (256 boys,44 girls) were enrolled in this study, 300 patients were divided into 3 groups: standard CT group (R0, n=38), 6 doses of R+ CT group (R6 group, n=87) and 4 doses of R+ CT group (R4 group, n= 175). The 3-years EFS were 82%±4.9%, 91.9±2.5%, and 91.2±2.3% respectively. (2)The median level of Ig(before CT, end of CT, 6 months after CT, 12 months after CT): IgA level were 0.78g/L, 0.44g/L, 0.52g/L, and 0.69g/L. IgM level were 0.84g/L, 0.23g/L, 0.48g/L,and 0.7g/L. IgG level were 7.2g/L, 5.6g/L, 5.7g/L, and 6.6g/L. (3) Comparison the median Ig level after CT between R4 and R6 group(according to Ig level before chemotherapy, data was 1:1 matched, and 78 children were included in R4 and R6 group): IgA, IgM and IgG level in R4 group were all higher than that in R6 group after CT, and there was a statistical difference in the change trend between 2 groups in Ig A and IgM level.
Conclusion: In children with high risk BL, rituximab combined with intensive chemotherapy can significantly improve the efficacy. Immune reconstitution is usually 6 months after the end of chemotherapy. There was no difference with treatment outcomes in R6 and R4 group, but the serum immunoglobulin reconstitution is faster after treatment in R4 group, IgA and IgG levels return to normal earlier.

Nano-structures of cobalt(II) metal-organic compound (Co-MOC) [Co(L)2(H2O)4] {1} (L = pyridine-3-carboxylic acid), have already been fabricated using two numerous experimental techniques which are including branched tube and sonochemical strategies. Besides the technique employed for1, an identical crystal structure was obtained. Scanning electron microscopy (SEM), powder X-Ray diffraction (PXRD), as well as Fourier transform infrared spectroscopy (FT-IR), were applied for the characterization of all compounds. Single-crystal X-Ray diffraction (SCXRD) analyses of1reveal which Co2+ions are 6-coordinated. Additionally, the temperature, time of reaction, the concentration of reactant, and sonication energy on the formation and ultimate morphology of compounds acquired by the sonochemical strategy are investigated. Ultimately, TGA (thermal gravimetric analyses), DTA (differential thermal analyses), as well as Hirshfeld surface analysis (HAS) of 1, were studied. Two strains of gram-negative Escherichi coli (E. coli) and gram-positive S. aureus) Staphylococcus aureus) was refined to the current compounds of1to determine their biological activities. These compounds exhibited adequate antibacterial activity within an abiotic environment.

Published: March 2023

Mesenchymal stem cells (MSCs) are a promising tool for treating immune disorders. However, the effect and mechanism of canine MSCs compared with other commercialized biologics for treating immune disorders have not been well studied. In this study, we investigated the characteristics and immunomodulatory effects of canine amnion membrane (cAM)-MSCs. We examined T lymphocytes from activated canine peripheral blood mononuclear cell (PBMC) proliferation. As a result, we confirmed that cAM-MSCs suppressed the proliferation capacity of T cells and cytotoxic activity. Moreover, we confirmed the therapeutic effect and mechanism of cAM-MSCs compared with oclacitinib, the most commonly used Janus kinase (JAK) inhibitor, as a treatment for canine atopic dermatitis (AD) using a mouse AD model. As a result, we confirmed that scores of dermatologic signs, tissue pathologic changes and inflammatory cytokines were significantly reduced by cAM-MSC treatment. In particular, cAM-MSCs were more effective than oclacitinib in the recovery of wound dysfunction and regulation of mast cell activity. Interestingly, subcutaneous injection of cAM-MSCs induced weight recovery, but oral administration of oclacitinib induced weight loss as a side effect. In addition, it was confirmed that the secretion of TGF-β1 and IDO by cAM-MSCs is directly involved in improving atopic dermatitis. In conclusion, this study suggests that cAM-MSCs can be developed as a safe canine treatment for atopic dermatitis without side effects through effective regeneration and immunomodulation.
Owner psychological characteristics predict dog behavioural traits
Authors: Clarke Harriet , Loftus Loni
Published: March 2023

There is extensive literature on the human-dog bond, less however on the role of owner psychological characteristics within this bond, and less still on how these might mediate dog behaviour. Accordingly, the aim of this study was to explore the relationship between owner levels of depression, anxiety and self-esteem and dog behaviour. Multiple linear regression was conducted to determine the predictive power of the psychological variables on dog behaviour using self-report. Conceptual content analysis was performed on three open questions to assess owner beliefs regarding their psychological influence on their dogs’ behaviour. 497 responses were collected. Anxiety and depression positively predicted increased levels of dog attachment and attention-seeking (p = < 0.001; p = 0.006), separation-related behaviour (p = < 0.001; p = < 0.001), stranger-directed aggression (p = < 0.001; p = < 0.001), stranger-directed fear (p = < 0.001; p = < 0.001), non-social fear (p = < 0.001; p = 0.01), dog-directed fear (p = 0.01; p = 0.01), touch sensitivity (p = < 0.001; p = < 0.001) and excitability (p = 0.004; p = < 0.001). Decreased self-esteem predicted dog non-social fear (p = 0.01). Fourteen themes were identified, including strong perceived bond, emotional dependency and anthropomorphism. Whilst only minimal within the vast interplay of factors impacted in canine ethology, owner psychological functioning plays a significant role in dog behaviour via numerous routes including interaction, emotion contagion and attachment. Understanding owner influence on dog behaviour can improve behaviour modification programmes, success of rehoming schemes, and improve wellbeing for both members of the human-dog dyad.
Cognitive and Economic Development
Authors: Gallup John Luke
Published: March 2023

Early childhood health conditions have large effects on the cognitive development, education and earnings of individuals. This paper assesses the impact of cognitive development on national economic development. Each risk factor for cognitive development also causes child mortality, making child survival a viable proxy for good cognitive development conditions. The cognitive development of current workers happened decades earlier when they were children. Child survival from a generation ago is one of the strongest correlates of economic growth in both low and high income countries. This evidence suggests that early cognitive development plays a major role in economic development.

This work reports a feasible method to fabricate a simple chemical functionalization of graphene oxide (GO) electrode, One-step hydrothermal synthesis of nitrogen-doped graphene quantum dots modified reduced graphene oxide (NGDQs/rGO2) using ammonium citrate and graphene oxide (GO) as raw materials. Ammonium citrate effectively acts as a nitrogen dopant cum reducing agent for graphene which remarkably enhances its electrochemical properties. Diffraction of X-rays (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS) were employed to characterize the structure and properties of the (NGDQs/rGO2), and the NGQDs/rGO2 was used as the electrode to test the electrochemical performance. According to the electrochemical test results, when the molar ratio of NGDQs to rGO is 1:2, the specific capacitance can reach 357 F/g at a current density of 1 A/g; after 1000 cycles, the capacitance retention rate is 82%. For comparison, under the same current density condition, the specific capacitance of the rGO electrode is only 74 F/g. Thus, the synthesized NGDQs/rGO2 using this simple, cost-effective, environment friendly method could be a potential candidate for high performance energy-storage applications.

Background: Lung adenocarcinoma (LUAD), the most common type of lung cancers, is a leading cause of cancer-related death. Early diagnosis is essential to improve the outcome of LUAD, especially to reduce its mortality. This study aims to explore individual and regulatory network of mRNA, lncRNA and miRNA with diagnostic or prognostic value in LUAD.
Methods: Differentially expressed RNAs of LUAD based on intersection of The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) databases were analyzed by bioinformatic methods.
Result: The competitive endogenous RNA (ceRNA) network was obtained with 40 differentially expressed (DE) mRNA nodes, 125 differentially expressed lncRNAs (DElncRNAs), and 7 differentially expressed miRNAs (DEmiRNAs), among which 37 were associated with prognosis and 11 were identified as diagnostic marker. The immune infiltration analysis suggested that components in the ceRNA may be related to changes in tumor immune microenvironment and development of LUAD.
Conclusion: This comprehensive analysis of the regulatory RNA network in LUAD has identified a list of RNA markers with implications for clinical use, RNAs in our constructed regulatory network are potential prognostic and diagnostic markers in LUAD.
A Comparison of the efficacies of differential item functioning detection methods
Authors: BAŞMAN Münevver
Published: March 2023

To ensure the validity of the tests is to check that all items have similar results across different groups of individuals. However, differential item functioning (DIF) occurs when the results of individuals with equal ability levels from different groups differ from each other on the same test item. Based on Item Response Theory and Classic Test Theory, there are some methods, with different advantages and limitations to identify items that show DIF. This study aims to compare the performances of five methods for detecting DIF. The efficacies of Mantel-Haenszel (MH), Logistic Regression (LR), Crossing simultaneous item bias test (CSIBTEST), Lord's chi-square (LORD), and Raju's area measure (RAJU) methods are examined considering conditions of the sample size, DIF ratio, and test length. In this study, to compare the detection methods, power and Type I error rates are evaluated using a simulation study with 100 replications conducted for each condition. Results show that LR and MH have the lowest Type I error and the highest power rate in detecting uniform DIF. In addition, CSIBTEST has a similar power rate to MH and LR. Under DIF conditions, sample size, DIF ratio, test length and their interactions affect Type I error and power rates.
An experimental measurement and numerical calculation method on friction temperature rise of sliding contact pairs - taking rail/wheel contact as an example
Authors: Wei Yunpeng , Wu Yaping , Chen Zhidong
Published: March 2023

The analysis of rail/wheel sliding friction heat is a very important research field. The numerical simulation is often adopted to calculate the friction heat, and experimental method is relatively few. In this paper, an experimental machine is designed to simulate the rail/wheel sliding contact. At the same time, a rail/wheel contact wear model and a friction heat transfer model are established. The characteristics of temperature on rail/wheel sliding contact are analyzed by experimental test and numerical calculation. The research results show that the temperature rise of wheel and rail is quick in the initial sliding contact stage, then gradually slows down. The temperature of wheel is higher than that of rail at the same depth from the contact surface. In the initial sliding stage, the wheel temperature rises faster than the rail temperature, which is related to the size of contact surface and the concentration degree of friction heat. Moreover, the results of this paper show that the temperature values of the rail/wheel obtained through experimental test and numerical calculation are in good agreement. The experimental and numerical calculation methods used in this article can be adopted to analyze the contact problems of other sliding friction pairs.
Fourier transform method for partial differential equations. Part 2. Existence and uniqueness of solutions to the Cauchy problem for linear equations
Authors:   Chechen State University, Gishlarkaev Vakha I.
Published: March 2023

The article proposes a method for analyzing the Cauchy problem for a wide class of evolutionary linear partial differential equations with variable coefficients. By applying the (inverse) Fourier transform, the original equation is reduced to an integro-differential equation, which can be considered as an ordinary differential equation in the corresponding Banach space. The selection of this space is carried out in such a way that the principle of contraction mappings can be used. To carry out the corresponding estimates for the operators generated by the transformed equation, we impose the conditions of finiteness in the space variable for the inverse Fourier transform of the coefficients, and the spaces of the coefficients of the original equation are determined from the Paley-Wiener Fourier transform theorems. In this case, the apparatus of the theory of the Bochner integral in pseudo-normed spaces, countably-normed spaces and Sobolev spaces is used. Classes of functions are distinguished in which the existence and uniqueness of solutions are proved. For equations with coefficients with separated variables, exact solutions are obtained in the form of a Fourier transform of finite sums for operator exponentials.

Published: March 2023

Although recently proved generalization of Enestr¨om-Kakey theorem by N.A.Rather et al. are applicable to the larger class of polynomials as compared to all other Enestr¨om- Kakeya type results, but are not applicable to the polynomials whose one or two coefficients are zero. For instance, if we consider the polynomial whose one or two coefficients are zero, then one can note that all Enestr¨om-Kakey type results including the recent generalizations by N.A.Rather et al. are not applicable to this polynomial. So it is interesting to look for the results applicable to such class of polynomials. Motivated by this, here we establish the following results applicable to such class of polynomials called the lacunary-type polynomials. In this paper, by relaxing the hypothesis of well-known Enestr¨om-Kakey theorem, we obtain a result which is applicable to the lacunary-type of polynomials and generalizes several well-known results concerning the location of zeros of polynomials. In addition to this, we show by examples that our results presents better information about the bounds of zeros of polynomials than some known results.

Authors:   St Petersburg Mining University, Brigadnov Igor A.
Published: March 2023

The article discusses a boundary value problem of nonlinear elasticity for mapping (deformation) in two weak formulations: in the form of a variational equilibrium equation and in the form of minimization of a multidimensional integral functional. Some questions of a mathematical correctness of the nonlinear elasticity BVP are discussed. Using methods of calculus of variations, by the example of two simple problems, it is proved that for some nonlinear elastic models in the corresponding boundary value problems there can be mappings that have discontinuities of the slip type, as well as there is the limit load - such a finite value of external forces, above which the boundary value problem has no solution at all.

Research on the urban water resources carrying capacity by using system dynamics simulation
Authors: Chen Xing , Xu Qin , Cai Jing
Published: March 2023

The relationship between water resources and social economy has become a restricting factor for sustainable development of cities around the world. Linhai City in eastern China has the fastest economic growing and population boom. The system dynamics model of water resources carrying capacity was established to analyze the interaction between society, economy and water resources of Linhai city. Six different modes of water resources utilization were designed. Taking total population, gross domestic product, industrial output value, tertiary industry output value, water consumption, water supply and sewage discharge as the measurement indexes, the research predicted the development status of water resources carrying capacity of Linhai City from 2015 to 2030 under different development modes. Through the simulation results, it is found that the water-saving measures can reduce the gap between water supply and demand only in the short term. In the long run, the adjustment of industrial structure can improve the water resources carrying capacity and simultaneously promote the economy. In addition, increase the water income sources as well as strengthen sewage treatment are also necessary to balance the water supply and demand.

The study is conducted to examine the climate change impact on rice Crop Water Requirement (CWR) and Net Irrigation Requirement (NIR) using the NASA Earth Exchange Global Daily Downscaled Projection (NEX-GDDP) coupled with the CROPWAT 8.0 model. The maximum temperature (Tmax), minimum temperature (Tmin), and rainfall projections for the baseline (years 1981–2015) and future (years 2030 and 2040) under Representative Concentration Pathway (RCP) 4.5 were derived from NEX-GDDP. To reduce the bias, linear scaling (LS) and the modified difference approach (MDA) were employed. Results show that LS performed better than the MDA along with improved statistical measures such as mean (μ), standard deviation (σ), and percent bias (Pbias), in the case of Tmax and Tmin (μ = 31.14 and 19.63 °C, σ = 5.75 and 6.78 °C, Pbias = 1.43 and 0.33%), followed by rainfall (μ = 2.67 mm, σ = 4.94 mm, and Pbias = 2.4%). The future climatic projections showed an increasing trend in both Tmax and Tmin, which are expected to increase by 1.7 °C by 2040. This would cause an increased range of 1.2 and 2% in 2030 and 2040, respectively. Due to a wide variation in effective rainfall (Peff), NIR could increase by 4 and 9% in 2030 and 2040, respectively. The above results may help formulate adaptation measures to alleviate the impacts of climate change on rice production.

Metallurgy is a major economic branch in Russia with more than 4000 enterprises operating in it and seventy percent of them being city-forming ones. This study focuses on cytological assessment of the oral mucosa and secretion from the middle meatus mucosa in workers employed in metallurgy. The aim of this study was to investigate cytological laboratory indicators in workers employed in metallurgy under exposure to adverse occupational factors. A clinical and diagnostic examination of workers employed at a metallurgical plant in Bashkortostan was performed in 2019–2020; it involved cytological studies of the oral mucosa (buccal epithelium) and the middle meatus mucosa (rhinocytogram). In this study, we applied the Index of cytogenetic disorders accumulation (Iac) that allows for cellular kinetics indicators. The overall hygienic assessment of working conditions for workers employed at the analyzed metallurgic plant corresponds to the hazard category 3.2–3.3 in accordance with the criteria outlined in the Guide R (harmful, class 2 or 3). The research results revealed cytogenetic disorders of buccal epithelial cells in the workers who had contacts with adverse occupational factors. Low likelihood of cytogenetic disorders was established for 66.67 % of the workers; moderate, 9.2 %; high, 23.81 %. We assessed rhinocytograms of the workers exposed to adverse occupational factors and revealed some signs of allergic inflammation characterized with high eosinophil count. The research results confirm high significance of diagnostic procedures for developing an algorithm for screening examinations of working population as well as indicators of health disorders under exposure to adverse occupational factors (noise, heating microclimate, industrial dust, gaseous chemicals).
Filial Duties in the Ugaritic Epic of Danilu and Aqhatu
Authors: Majewski Marcin
Published: March 2023

The list of filial duties from the Aqhatu story constitutes a passage unique to the literature of the ancient Near East, emphasized in the epic by its fourfold repetition in close proximity. This is why the list has attracted much attention of scholars, who are particularly interested in the wisdom nature of the list, the ancestor worship in Ugarit and in the Ancient East, the family ritual and the responsibilities of children towards their parents, as well as the Sitz im Leben of the list, considered by some to be part of a larger and independent work, which has been included in the Aqhatu story because of loose connections with the topic of son and heir. As the current translation and interpretation efforts seem insufficient, the article proposes a new translation and a new attempt to highlight the meaning and the context of both individual duties and the entire list.

Published: March 2023

Pain and discomfort in the coccyx or tailbone area is called as coccydynia or coccygodynia. Despite its small size, the coccyx, which forms the terminal of the spine, has an important role to support the balanced distribution of body weight, especially in the sitting position, due to its relationship with the surrounding muscles, ligaments and bone structures. The problems of this area for various reasons manifests itself with localized discomfort and pain in the sacrococcygeal region. Our aim in this paper is to review the etiology, pathophysiology, clinical findings, diagnosis and treatment methods of coccydynia in light of the current literature.
Creatividad e ideales antropológicos: el ser humano ubicuo entre la homogeneización y la diversidad
Authors: Polo-Flórez Viviana
Published: March 2023

El despliegue de la transformación puede ser visto como el desarrollo, que da poderío y que aviva la creatividad[1]. Esta, como esa capacidad que define a la especie humana, sugiere articulaciones desde la conformación del sujeto en relación con el tiempo y su contexto, evidenciada en la creación y la destrucción como variables permanentes de su existencia. Este escrito propone una mirada a la creatividad como dispositivo abierto, que es susceptible de clasificarse socialmente y desde la formación de tipo positivista entre lo que se considera bueno y lo que no. De este modo, pone de manifiesto cómo las capacidades y aspiraciones del ser humano han estado mediadas por la necesidad de cambiar de modo permanente todo lo que lo rodea, sin medir necesariamente sus consecuencias.

[1] En sus obras El pensamiento creativo (1995) y Pensamiento práctico (1992), Edward de Bono valida la creatividad como algo inherente a los seres humanos, cuyo óptimo desarrollo se da a partir de la eficiencia de los procesos y su finalidad. La inocencia, el desconocimiento, la curiosidad, la motivación son elementos que conforman la vocación creativa que caracteriza al ser humano.
Universidad. Diversidad, libertad, creatividad
Authors: Marchisio Mariela
Published: March 2023

Este artículo fue pensado y escrito desde una ciudad mediterránea y universitaria que gestó, en 1918, la Reforma Universitaria que aún nos marca y nos permite hackear continuamente las verdades instaladas; estoy efectivamente escribiendo desde Córdoba, la Docta; más precisamente desde la Universidad Nacional de Córdoba. Sin embargo, nada de esto hubiera sido posible sin la invalorable mirada crítica y propositiva de un amigo colombiano, que a estas alturas podría ya ser colaborador directo de este artículo. Mi amigo es doctor, pero sobre todo es Alfredo. Imagino que a estas alturas ya todos saben que me refiero al Dr. Alfredo Gutiérrez Borrero. Con Alfredo hemos compartido textos, charlas y revisiones críticas de distintos borradores previos a este ensayo. Por eso lo menciono especialmente, convencida de la necesidad de la construcción colaborativa de miradas y revisiones críticas de conceptos y reflexiones que siempre enmarcan nuestros modos ser y estar en los lugares que ocupamos circunstancialmente.
Experiencia de un accionar mutuante
Authors: Detonante Diseño
Published: March 2023

Este es un escrito híbrido, mutante y fronterizo, porque es realizado a dos manos, e irá narrando, valiéndose de nuestro accionar, las trochas que como Diseño Detonante hemos venido y vamos caminando, las fronteras que habitamos y nos habitan, las mutaciones que el encuentro y la incertidumbre han propiciado. Empezamos con una ficción que, como toda ficción, es tan real como las realidades, que a su vez son ficciones; una primera invitación a situarnos en un espacio/tiempo compartido con quien nos lee, y a formar una complicidad que permita cuestionar el contexto propio. Ya que nuestro accionar habita la frontera de la teoría y la práctica haciendo de esta un lugar otro, la propuesta es leer con apertura al salto, a la conexión con las propias trochas y caminos, a desobedecer, mientras compartimos las trochas de nuestras propias desobediencias y mutaciones comunes, individuales, consteladas, sus resonancias y repercusiones.

Terawatt laser pulses obtained after temporal compression due to nonlinear spectrum broadening in thin glass plates with subsequent dispersion compensation by chirped mirrors are experimentally characterized by spatially encoded spectral phase interferometry. The proposed method allowed to reconstruct the spectral and temporal phase of obtained 16 fs laser pulses with up to 20 mJ of energy in a single-shot mode with spatial resolution.

The application of the technique of resonant excitation of photoluminescence at low temperatures using a narrow-band tunable laser significantly expands the possibilities of spectral investigation of individual luminescent centers in nanodiamonds, even in conditions of high concentrations of such centers. In this paper, a comparative analysis of the spectral characteristics of individual Silicon-Vacancy (SiV) centers in nanodiamonds grown with a spontaneous nucleation technique on germanium and silicon substrates is carried out. Studied diamond nanoparticles have a characteristic size of 300 nm and contain large ensembles of SiV centers. It was found that during the transition from silicon substrates, which are traditionally used in the CVD synthesis of diamonds, to germanium substrates, the spectral characteristics of the photoluminescence of SiV centers almost do not change.
