A Study of the English Translation of Characteristic Cuisines of the Hexi Corridor from the Perspective of Multimodal Discourse Analysis

Given the diversity of geographical and cultural backgrounds,it is difficult to find precise counterparts of many food-related vocabularies in the unique dietary culture of the Hexi Corridor in the target language,making it challenging to fully convey the essence of its local dietary culture in translation.To achieve the purpose of translation,the theory of multimodal discourse analysis provides an ideal translation approach through the language mode,image mode,sound mode,and the synergistic effect of multimodalities,which can accurately address the deficiencies in the translation of dietary culture.Through this research,it is not only possible to highlight the unique charm of the dietary culture of the Hexi Corridor but also to build a bridge for its international dissemination,promoting cross-border cultural exchanges and mutual understanding.

Experimental Study on Aerodynamic Characteristics of the Model Wind Rotor System and on Characterization of A Wind Generation System

In order to investigate the aerodynamic characteristics of 6-MW wind turbine, experimental study on the aerodynamic characteristics of the model rotor system and on characterization of a wind generation system is carried out. In the test, a thrust-matched rotor system and a geometry-matched rotor system, which utilize redesigned thrustmatched and original geometry-matched blades, respectively, are applied. The 6-MW wind turbine system is introduced briefly. The proper scaling laws for model tests are established in the paper, which are then implemented in the construction of a model wind turbine with optimally designed blades. And the parameters of the model are provided. The aerodynamic characteristics of the proposed 6-MW wind rotor system are explored by testing a 1:65.3 scale model at the State Key Laboratory of Ocean Engineering at Shanghai Jiao Tong University. Before carrying out the wind rotor system test, the turbulence intensity and spatial uniformity of the wind generation system are tested and results demonstrate that the characterization of the wind generation system is satisfied and the average turbulence intensity of less than 10% within the wind rotor plane is proved in the test. And then, the aerodynamic characteristics of 6-MW wind rotor system are investigated. The response characteristic differences between the thrust-matched rotor system and the geometry-matched rotor system are presented. Results indicate that the aerodynamic characteristics of 6-MW wind rotor with the thrust-matched rotor system are satisfied. The conclusion is that the thrust-matched rotor system can better reflect the characteristics of the prototype wind turbine. A set of model test method is proposed in the work and preparations for further model basin test of the 6-MW SPAR-type floating offshore wind turbine system are made.

A comparative study of the main factors controlling geohazards induced by 10 strong earthquakes in Western China since the Wenchuan earthquake in 2008

Determining the main controlling factors of earthquake-triggered geohazards is a prerequisite for studying earthquake geohazards and post-disaster emergency response.By studying these factors,the geomorphic and geological factors controlling the nature,condition,and distribution of earthquake-induced geohazards can be analyzed.Such insights facilitate earthquake disaster prediction and emergency response planning.The authors combined field investigations and spatial data analysis to examine geohazards induced by seismic events,examining ten earthquakes including the Wenchuan,Yushu,Lushan events,to elucidate the main control factors of seismic geohazard.The authors observed that seismic geohazard occurrence is usually affected by many factors,among which active nature of the seismogenic fault,seismic peak ground acceleration(PGA),topographic slope and geomorphic height differences,and distance from the fault zone and river system are the most important.Compared with strike-slip earthquakes,thrust earthquakes induce more high-altitude and high-speed remote landslides,which can cause great harm.Slopes of 0°–40°are prone to secondary seismic geohazards,which are mainly concentrated 0–6 km from the river system.Secondary geohazards are not only related to seismogenic fault but also influenced by the associated faults in the earthquake area.The maximum seismic PGA and secondary seismic geohazard number are positively correlated,and the horizontal and vertical ground motions play leading and promoting roles in secondary geohazard formation,respectively.Through the research,the spatial distribution of seismic geohazards is predicted,providing a basis for the formulation of emergency response plans following disasters.

The Main Characteristics and Disposal of Municipal Garbage in Changchun City of China

Based on current situations of Chinese garbage management and disposal, this paper is centered on introduction of some research results of household garbage in Changchun, capital city of Jilin Province, northeast China. From the viewpoint of man the earth system, garbage is characterized by sociality, temporal and spatial differentiation and limitation and other features, which imply that the garbage research being involved with natural science and social science should not only focus on the natural features but also on the social features. Compared to some developed cities, the material composition of garbage in Changchun is typically characterized by high moisture content, low combustion value and minor recyclable materials. Concentration, cycle shaping and self similarity characterize the garbage distribution. The tracing investigation on 683 households ten times shows that three fourths of the total garbage yield in Changchun is derived from non domestic units and that the attention of garbage management, especially source reduction, should be focused on the non domestic units. The GM(1,1) prediction model has been set up and the prediction result shows that the amount of garbage yield of Changchun in 2004 will be up to 1,500,000 tons. Investigation of environmental consciousness to garbage problems have been carried out. Based on the above characteristics of garbage, the disposal countermeasures of Changchun garbage have been suggested.

A STUDY OF THE CHARACTERISTICS OF γ-GLUTAMYLTRANSPEPTIDASE OF HUMAN ESOPHAGEAL CANCER

γ-Glutamyltranspeptidase (γ-GT) from human esophageal cancer, normal esophageal mucosa and normal kindney were partially purified and their biochemical and immunological properties were studied. (1) The γ-GT activity of esophageal cancer was higher than that of normal mucosa, yet still much lower than that of normal kidney. (2) The Michaelis constant and optimum pH of esophageal cancer γ-GT were the same as those of normal kidney tissue. (3) After staining of γ-GT activity, two molecular clusters, i.e. 100kD and 380kD γ-GT were shown in esophageal cancer by 4-20% linear gradient PAGE and the lOOkD γ-GT showed higher activity. (4) The γ-GT of esophageal cancer was immunologically identical with normal enzyme in double immunodif-fusion and immunoelectrophoresis. (5) In double lectin-diffusion, affinity column and crossed immuno-affino-electrophoresis, it was demonstrated that the carbohydrate components of γ-GT from esophageal cancer were heterogeneous and rich in D-Mannose, D-Glucose and N-Acetyl-Glucosamine. The relationship between the appearance of 100kD γ-GT cluster and the heterogeneous carbohydrate components will be further studied.

A STUDY OF THE BIOLOGICAL CHARACTERISTICS OF HUMAN HEPATOMA XENOGRAFTS IN NUDE MICE AFTER IRRADIATION

Cell growth kinetics and changes in AFP in nude mice with human hepatoma xenografts were evaluated using the flow cytometry method. After receiving 10 Gy of radiation, the mice showed a marked delay in tumor growth; approximately 1 Gy of radiation caused a tumor growth delay of one day. Irradiation altered various phases of the cell cycle. An acute and temporary block of G2 cells was characteristic; FCM measurements demonstrated that about 58% of cells were blocked in the G2 phase and this blocking effect lasted 90 hours after an irradiation of 10 Gy. This indicated that human hepatoma xenografts in nude mice were quite sensitive to irradiation. It was also noted that the AFP decreased for 96 hours after irradiation. Changes in G2 cells after irradiation may be closely related to changes in AFP.

Preliminary Study of the Characteristics and Genesis of Arsenate Minerals in the Oxidized Zone of the Debao Skarn-Type Cu-Sn Ore Deposit in Guangxi

Through the study of the oxidized zone of the Debao skarn-type Cu-Sn deposit in Guangxi, the authorshave found 14 arsenate minerals, most of which are for the first time reported in China. They are mainly Cuarsenate minerals with subordinate Cu-Pb arsenate minerals and minor Fe-Pb-Ba varieties. Based on their paragenesis these minerals may be divided into the following series: (1) the clinoclasite-olivenite-cornwallite- cornubite- debaoite- copper silicarsenate association, (2) the scorodite- carminite- beudan-tite-bayldonite- duftite association, and (3) the scorodite-Ba-bearing pharmacosiderite- dussertite association. Arsenate minerals are formed generally in the oxidized zone of the sulfide-type deposits which lie in thewarm, humid and rainy torrid-subtropical zone with pH=6-8 and contain large amounts of arsenopyrite andcarbonate rocks.

Effectiveness of magnetic resonance imaging and spiral computed tomography in the staging and treatment prognosis of colorectal cancer

BACKGROUND Colorectal cancer(CRC)is a prevalent cancer type in clinical settings;its early signs can be difficult to detect,which often results in late-stage diagnoses in many patients.The early detection and diagnosis of CRC are crucial for improving treatment success and patient survival rates.Recently,imaging techniques have been hypothesized to be essential in managing CRC,with magnetic resonance imaging(MRI)and spiral computed tomography(SCT)playing a significant role in enhancing diagnostic and treatment approaches.AIM To explore the effectiveness of MRI and SCT in the preoperative staging of CRC and the prognosis of laparoscopic treatment.METHODS Ninety-five individuals admitted to Zhongshan Hospital Xiamen University underwent MRI and SCT and were diagnosed with CRC.The precision of MRI and SCT for the presurgical classification of CRC was assessed,and pathological staging was used as a reference.Receiver operating characteristic curves were used to evaluate the diagnostic efficacy of blood volume,blood flow,time to peak,permeability surface,blood reflux constant,volume transfer constant,and extracellular extravascular space volume fraction on the prognosis of patients with CRC.RESULTS Pathological biopsies confirmed the following CRC stages:23,23,32,and 17 at T1,T2,T3,and T4,respectively.There were 39 cases at the N0 stage,22 at N1,34 at N2,44 at M0 stage,and 51 at M1.Using pathological findings as the benchmark,the combined use of MRI and SCT for preoperative TNM staging in patients with CRC demonstrated superior sensitivity,specificity,and accuracy compared with either modality alone,with a statistically significant difference in accuracy(P<0.05).Receiver operating characteristic curve analysis revealed the predictive values for laparoscopic treatment prognosis,as indicated by the areas under the curve for blood volume,blood flow,time to peak,and permeability surface,blood reflux constant,volume transfer constant,and extracellular extravascular space volume fraction were 0.750,0.683,0.772,0.761,0.709,0.719,and 0.910,respectively.The corresponding sensitivity and specificity values were also obtained(P<0.05).CONCLUSION MRI with SCT is effective in the clinical diagnosis of patients with CRC and is worthy of clinical promotion.

Undifferentiated embryonal sarcoma of the liver:Clinical characteristics and outcomes

BACKGROUND Undifferentiated embryonal sarcoma of the liver(UESL)is a rare liver malignancy originating from primary mesenchymal tissue.The clinical manifestations,laboratory tests,and imaging examinations of the disease lack specificity and the preoperative misdiagnosis rate is high.The overall prognosis is poor and survival rate is low.AIM To investigate the diagnosis,treatment,and prognosis of UESL.METHODS We performed a retrospective,single-center cohort study in Shengjing Hospital of China Medical University,which is a central hospital in northeast China.From 2005 to 2017,we recruited 14 patients with pathologically confirmed UESL.We analyzed the clinical manifestations,laboratory tests,imaging examinations,pathological examinations,therapy,and prognosis of these patients.RESULTS There were nine males and five females aged 2-60 years old included in the study.The major initial symptoms were abdominal pain(71.43%)and fever(57.14%).Preoperative laboratory tests revealed that seven patients had increased leukocyte levels,four showed a decrease in hemoglobin levels,seven patients had increased glutamyl transpeptidase levels,nine had increased lactate dehydrogenase levels,and three showed an increase in carbohydrate antigen 199.There was no difference in the rate of misdiagnosis in preoperative imaging examinations of UESL between adults and children(6/6 vs 5/8,P=0.091).The survival rate after complete resection was 6/10,while that after incomplete resection was 0/4(P=0.040),suggesting that complete resection is important to improve survival rate.In total,five out of the eight children achieved survival.During the follow-up,the maximum survival time was shown to be 11 years and minimum survival time was 6 mo.Six adult patients relapsed late after surgery and all of them died.CONCLUSION Preoperative imaging examination for UESL has a high misdiagnosis rate.Multidisciplinary collaboration can improve the diagnostic accuracy of UESL.Complete surgical resection is the first choice for treatment of UESL.

An Experimental Study on the Effect of the Side Hull Symmetry on the Resistance Performance of a Wave‑Piercing Trimaran

This paper presented the results of an experimental investigation into the resistance performance of a wave-piercing trimaran with three alternative side hull forms,including asymmetric inboard,asymmetric outboard,and symmetric at various stagger/separation positions.Model tests were carried out at the National Iranian Marine Laboratory(NIMALA)towing tank using a scale model of a trimaran at the Froude numbers from 0.225 to 0.60.Results showed that by moving the side hulls to the forward of the main hull transom,the total resistance coefficient of trimaran decreased.Findings,furthermore,demonstrated that the symmetry shape of the side hull had the best performance on total resistance among three side hull forms.Results of this study are useful for selecting the side hull configuration from the resistance viewpoint.

Effects of Rigid Vegetation on the Turbulence Characteristics in Sediment-Laden Flows

The effects of rigid vegetation on the turbulence characteristics were experimentally studied in the interior water flume. An ADV was used to determine the three dimensional turbulent velocities in clear water flow without vegetation, sediment-laden flow without vegetation, sediment-laden flow with submerged vegetation and sediment-laden flow with non-submerged vegetation. By experimental and theoretical analysis, the effects of rigid vegetation on the distribution of averaged velocities, turbulence intensities and Reynolds stress were summarized. In sediment-laden flow with submerged vegetation, the averaged stream wise velocities above the top of vegetation fit well with the log distribution low. The three-dimensional turbulence intensities increase from the bottom until they reach the maximum at the top of the vegetation. The method to calculate the shear velocity with the maximum of the Reynolds stress is recommended. In sediment-laden flow with non-submerged vegetation, the turbulence problems cannot be explained by theory of bed shear flow. The average velocities, turbulence intensities and Reynolds stress approximate uniformly distributed along vertical direction.

Study of aquatic chemical characteristic in some bays along the coastal region of Zhejiang Province

In this paper,the aquatic chemical characteristics in the Hangzhou Bay,Xiangshan Bay and Leqing Bay along the coastal region of Zhejiang Province are discussed . Results show that the seasonal variations of chemical elements are obvious. The distribution of silicate in Hangzhou Bay and contents of dissolved oxygen and nutrient in the Xiangshan Bay are found to be unusual in winter. Correlations among the elements are complex. The content of nutrient in the Hangzhou Bay is higher than that in Xiangshan Bay and the content of nutrient in the Xiangshan Bay is higher than that in the Leqing Bay . The variation of the ratio of N/P is obvious. This reflects the aquatic chemical characteristics in the bay. Finally, this paper also discusses the reason why the aquatic chemical characteristics in the bays are unusual.
