Study of a mixed problem for a nonlinear elasticity system by topological degree

"In this paper, we consider a mixed problem for a nonlinear elasticity system with laws of general behavior. The coefficients of elasticity depends on x meanwhile the density of the volumetric forces depends on the displacement. The main aim of this paper is to apply the Schauder's fixed point theorem and the techniques of topological degree to prove a theorem of the existence and the uniqueness of the solution of the corresponding variational problem."

The Protective Effect of a Novel Cross-Linked Hemoglobin-Based Oxygen Carrier on Hypoxia Injury of Acute Mountain Sickness in Rabbits and Goats

Hypoxia is the major cause of acute altitude hypoxia injury in acute mountain sickness (AMS). YQ23 is a kind of novel bovine-derived, cross-linked hemoglobin-based oxygen carrier (HBOC). It has an excellent capacity for carrying and releasing oxygen. Whether YQ23 has a protective effect on the acute altitude hypoxia injury in AMS is unclear. In investigating this mechanism, the hypobaric chamber rabbit model and plain-to-plateau goat model were used. Furthermore, this study measured the effects of YQ23 on the ability of general behavior, general vital signs, Electrocardiograph (ECG), hemodynamics, vital organ injury markers, and blood gases in hypobaric chamber rabbits and plain-to-plateau goats. Our results showed that the ability of general behavior (general behavioral scores, GBS) (GBS: 18 ± 0.0 vs. 14 ± 0.5, p < 0.01) and the general vital signs weakened [Heart rate (HR, beats/min): 253.5 ± 8.7 vs. 301.1 ± 19.8, p < 0.01; Respiratory rate (RR, breaths/min): 86.1 ± 5.2 vs. 101.2 ± 7.2, p < 0.01] after exposure to plateau environment. YQ23 treatment significantly improved the ability of general behavior (GBS: 15.8 ± 0.5 vs. 14.0 ± 0.5, p < 0.01) and general vital signs [HR (beats/min): 237.8 ± 24.6 vs. 301.1 ± 19.8, p < 0.01; RR (breaths/min): 86.9 ± 6.6 vs. 101.2 ± 7.2, p < 0.01]. The level of blood PaO2 (mmHg) (115.3 ± 4.7 vs. 64.2 ± 5.6, p < 0.01) and SaO2(%) (97.7 ± 0.7 vs. 65.8 ± 3.1, p < 0.01) sharply decreased after exposure to plateau, YQ23 treatment significantly improved the blood PaO2 (mmHg) (97.6 ± 3.7 vs. 64.2 ± 5.6, p < 0.01) and SaO2(%) (82.7 ± 5.2 vs. 65.8 ± 3.1, p < 0.01). The cardiac ischemia and injury marker was increased [troponin (TnT, μg/L):0.08 ± 0.01 vs. 0.12 ± 0.02, p < 0.01], as well as the renal [blood urea nitrogen (BUN, mmol/L): 6.0 ± 0.7 vs. 7.3 ± 0.5, p < 0.01] and liver injury marker [alanine aminotransferase (ALT, U/L): 45.8 ± 3.6 vs. 54.6 ± 4.2, p < 0.01] was increased after exposure to a plateau environment. YQ23 treatment markedly alleviated cardiac ischemia [TnT (μg/L):0.10 ± 0.01 vs 0.12 ± 0.02, p < 0.01] and mitigated the vital organ injury. Besides, YQ23 exhibited no adverse effects on hemodynamics, myocardial ischemia, and renal injury. In conclusion, YQ23 effectively alleviates acute altitude hypoxia injury of AMS without aside effects.

TRANSLATION RESEARCH OF COLD MOUNTAIN POEMS FROM THE PERSPECTIVE OF TRANSLATOR BEHAVIOR CRITICISM

The spread of Cold Mountain (Han Shan) poems is a text travel. As an important phenomenon of Chinese culture as well as a world cross-cultural phenomenon, it has significant research value. From the perspective of translator behavior criticism, the translator's volitional nature, identity and the social context in which the translator's behavior takes place all influence the translator's internal and external translation behavior. Based on the "Truth-seeking-Utility-attaining" Continuum Mode of Evaluation, we find that different sinologists display different translator's behavior characteristics when translating Cold Mountain poems into English. This paper summarizes the general behavior rules of translators, which can provide some references for the "going out" of Chinese culture. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0885/a.php" alt="Hit counter" /></p>

Psychoacoustic evaluation of soundscapes by means of repeated measurements

Research on soundscape explore facets of how acoustic environments affect human perception in context. By means of psychoacoustic parameters the sound character of acoustic environments can be described comprehensively as those parameters play an important role with respect to manifold auditory sensations. Although there seems to be a consensus of the benefit of psychoacoustics for soundscape evaluations and the ISO/TS 12913-2 particularly requests to give consideration to psychoacoustic indicators in soundscape investigations rather little is known about the relationships between psychoacoustic quantities and significant soundscape dimensions. Numerous investigations aimed to establish links between psychoacoustics and soundscape appraisal, but the gained results were often not suited for generalization. Moreover, it is rather unclear how urban locations vary in their sound character over longer periods and how the level of variation drives soundscape assessments. In order to establish an understanding of potential psychoacoustic characterization of urban locations for soundscape evaluations, repeated measurements of different locations are analyzed and the general behavior of psychoacoustic quantities derived. Based on these investigations it is intended to expand knowledge on the usefulness of psychoacoustics from the perspective of the soundscape approach.

Modeling of the deuteron wave function in coordinate representation and calculations of polarization characteristics

Modeling of the deuteron wave function in coordinate representation for the nucleon-nucleon potential Reid93 were performed. For this purpose, the asymptotics of the radial wave function near the origin of coordinates and at infinity are taken into account. The most simple and physical asymptotics were applied. In this case, the superfluous knots of both components of the deuteron wave function for the coordinate value r=0.301 fm were compensated. Taking into account the asymptotics of the wave function has little effect on the general behavior of the calculated polarization characteristics of t20 and Ауу. Particular points of the transmitted momentum have been identified, where the tensor deuteron polarization t20 and the tensor analyzing power Ауу show a clear difference.

Establishment and Comparison of an Experimental Kidney Yang Deficiency Syndrome Rat Model Caused by Hydrocortisone, Adenine, and Dexamethasone Combined with Adriamycin in Rats

Objective: The paper is aimed to establish a method for renal injury in rats with kidney yang deficiency syndrome (KYDS) of the stable by comparing different model establishment methods and optimize the final modeling method.Method: In order to mimic water metabolism disorder of KYDS- a diagnostic pattern in traditional Chinese medicine (TCM), we made a comparison of hydrocortisone-induced, adenine-induced, dexamethasone combined with adriamycin-induced KYDS rat model according to testing general behavior, detecting Hypothalamus-pituitary-adrenal (HPA) axis function and renal function also making use of drug action. Additionally, the effect of adenine at a dose of 100 mg/kg, 150 mg/kg, and 200 mg/kg, respectively, on establishment of KYDS model was investigated in rats. Finally, Shenqi Wan (SQW, 3 g/kg) was used to estimate the deterioration of adenine that is associated with KYDS. Result: Three KYDS model rats all exhibited weight loss, anal temperature drop, reduced food intake and dysfunction of the Hypothalamus-pituitary-adrenal (HPA) axis, which could be alleviated by SQW. However, different from other two methods, adenine-induced rats were prominently manifested as water and fluid metabolism disorders (sharply increased water intake and urine volume). Renal injury in adenine-induced rats was more obvious than it in hydrocortisone-induced rats and dexamethasone combined with adriamycin-induced rats. And renal toxicity caused by adenine was reversible by SQW treatment. Water metabolism disorder in adenine-induced rats was more closer to clinical symptoms of patients with KYDS. Subsequently, we found different dose of adenine gavage (100, 150, 200 mg/kg) for 14 days result in general behavior change, dysfunction of HPA axis and renal function damage. But only medium-dose of adenine induced toxicity could be reversed by SQW treatment for 21 days.Conclusion: The result of the comparison between the three modeling methods showed that adenine-induced was more effective to establish the KYDS model, and only a medium-dose of adenine for inducing renal poison could be recovered by SQW treatment. Therefore, a medium-dose of adenine was optimal for the establishment of the KYDS rat model.Trial registration : This is an animal experiment, trial registration is not necessary.

Egg and Jerry

In this paper we present a sociolinguistic research conducted on Italian schoolchildren learning English as LS. Following on from renowned researchers, we focused on a less studied population, that is school-aged monolingual children. Our participants consist in 15 students of a 4th grade class at a primary school in Pavia, all aged around 9 y.o, 7 boys and 8 girls. All children do not present any recorded cognitive problems and they are all Italian L1 speakers with little or no use of other languages at home, and English learnt as LS since the beginning of primary school at age 6. We recorded all children performing a task of re-narration of a “Tom & Jerry” cartoon, firstly in Italian and then, after one week, in English. The corpus consist of about 2h 45’ of recordings, transcribed and annotated in ELAN. Lexical knowledge in English was also tested through a questionnaire before the recordings. The results were analyzed both qualitatively and, partly, quantitatively. During qualitative analysis, two elements were observed: (1) general tendencies in speakers general behavior and (2) differences in the relationship between syntactic-conversational system and gesture system in relation to L1/L2. The quantitative analysis show a difference in the use of beats gestures and iconic ones between L1 and LS, but also between boys and girls.

School Personnel Perception of Parental Involvement and Students’ Behavior Problems: Practical Implications

School is a privileged context to prevent specific behavior problems. Parental involvement in school activities is crucial to promote social functioning. This study aimed to access the Portuguese school personnel perception of parental involvement and students’ behavior problems. A study with 333 school personnel, aged between 29 and 66 ( M = 50.84, SD = 7.54), was developed. School personnel’s participants rated parental involvement as low and nearly one in five professionals rated student’s general behavior as bad. A significant association between parental involvement and the perception of students’ general behavior was found. 80% of the professionals rating student’s general behavior as bad also rating parental involvement as poor. Additional research into implications of parental involvement in school activities and school students’ behavior problems is necessary aiming assessment, prevention, and intervention strategies in this area.

General Behavior and Indebtedness of Tocantins-Brazil between 2000 and 2018

The aim of this study is to analyze the general behavior and indebtedness of Tocantins State in Brazil, between the years 2000 and 2018. In order to reach the results, short-and long-term indicators of debt, as well as the behavior of the indebtedness are estimated. Data were collected from government account, extracted from the sites of the Audit Office of National Treasury Secretary and from the Estate Secretary of Tocantins. This paper is grounded on Agency Theory applied to public sector, and on descriptive statistics techniques by means of dispersion measures. Results show trends in behavior of public indebtedness in Tocantins. The first and second ones reveal tendency to decrease in the second half of the year, and to increase in the first half of the year, depicting a larger debt than the State paying capacity. The second and third trends, although distinct indicators, converge due to the increase of the debt indicators between 2014 and 2015. Keywords: Indebtedness, Indicators, Public Account, Tax Liability Law, Tocantins.
