Objective Virtual touch tissue quantification (VTQ) of acoustic radiation force impulse (ARFI) is a new quantitative technique to measure stiffness. The study was aimed assess the usefulness VTQ in diagnosis thyroid nodules. Methods 173 pathologically proven nodules 142 patients were included and all examined by conventional ultrasound (US), elasticity imaging (EI) ARFI. stiffness for expressed as shear wave velocity (SWV) (m/s). Receiver-operating characteristic curve (ROC) analyses...

Objectives- Acoustic radiation force impulse elastography is a newly developed ultrasound elasticity imaging technique that included both Virtual Touch tissue quantification and (VTI; Siemens Medical Solutions, Mountain View, CA). This study aimed to evaluate the usefulness of VTI in differentiating malignant from benign thyroid nodules. Methods- 192 consecutive patients with nodules (n = 219) who underwent surgery for compressive symptoms or suspicion malignancy. Tissue stiffness on was...

Green infrastructure is an approach to land planning that aims restore and manage the natural environment within human contexts. Its widespread use in post-industrial urban peri-urban settings recognizes need reconcile environmental issues regenerate social cultural connections with landscape. However, green seldom discussed rural contexts, where efficient production practices increasingly dominate agriculture, invariably overwhelming associations its qualities. In China, a government policy...

Abstract Deindustrialization in the sense of a decline share industry GDP, generally observed developed countries, is explained by three‐sector model. While this model shows ‘normal’ level deindustrialization, study proposes to use unbalanced trade assess existence undue deindustrialization 21 major countries and empirically confirms its existence. At finer sectoral levels, grouping these into Europ16 Pacific5, direct indirect impacts on over period 1991–2018 are assessed. The results...

From the trade theory point of view, this positive change can be explained by gains from comparative advantage.The macroeconomic improvement comes decrease in production some sectors which a country has no advantage and increase those costs are lower (or) factors more abundant.Without necessarily doubting its normative or welfare implications, there concerns about mainstream gains-from-comparativeadvantage argument.In relation to certain countries such as China, most African have almost any...

We use the investments of Chinese and Indian MNCs in Europe to test hypothesis that main motivation Southern for investing Northern countries is asset-or technology-seeking.After showing previous work has not adequately tested this due its country-level FDI flow data, we conduct our tests with count data models tests.The results reveal strong, whereas MNCs, their excessive concentration UK software sector, have a weaker asset-seeking than MNCs.

La théorie néo-institutionnelle est importante pour le développement parce que les coûts de transaction élevés et l'inefficacité du système des droits propriété constituent faiblesses capitales pays en voie développement. Grâce à son avantage méthodologique dans traitement micro-macro macro-micro transitions, cette capable d'analyser comment par quels mécanismes comportement individus soumis la structure institutionnelle évolue avec changements conditions économiques. approche...

We developed a model to explore the comparative advantage based intra-national trade in developing countries, as contrast models driven by increasing returns and agglomeration that prevail world.The incorporates technological spillovers trade.The findings suggest share of region is inversely proportional its level, economic growth diffuses along network from country, through advanced regions into less regions.Internal costs exert multiplied hindering effect, stronger than border barriers, on...

The thermal insulation performance of the roofs in rural residential buildings western China was discussed this paper. A type building that had been extensively constructed southern Shaanxi region selected as basic model to compare and analyse different roof forms under natural heating conditions. flat roof, sloping combined with a (SF roof) were used by residents. results showed SF better energy-saving compared other two types roofs. Further discussion air layer reason for its performance....

Yong He, Jean-Christophe Simon — The dynamism of the Chinese agriculture in face world trade : A new Big Bang China's agricultural production presents a major challenge to national development and trade. Ten years ago, L. Brown (1994) predicted that China would reduce its cultivated surfaces due rapid industrialisation, leading crisis for grain markets, thus causing an undesirable Bang. Recent data from sources does not back up this analysis. Three scenarios probable future trends consider...

Benign metastasizing leiomyoma (BML) is a rare disease associated with pelvic leiomyoma. We report 18 F-FDG and 68 Ga-FAPI PET/CT findings in 51-year-old woman multiple BMLs. The mass the abdominopelvic cavity other metastatic lesions showed highly increased uptake, whereas uptake of those was low. Our demonstrates that different result detecting BML to PET/CT, may be promising method for whole-body evaluate metastases.

We built a database of two samples patients surveyed within the same regions in rural China over time interval 18 years, and presumed varying demand heterogeneity due to income increase people aging. find that while mean price distance negative effects on choice were present both periods, their differences heterogeneity, which confirmed with mixed multinomial logit (MMNL), could have crucial importance avoiding erroneous policy making based merely effects. also (MNL) MMNL are able predict...

Dans cette étude, nous montrons que l’accroissement de la présence Chine et des États-Unis a été essentiellement motivé par perspective d’un meilleur accès aux ressources naturelles africaines. Nous expliquons que, premièrement, l’impact positif chinoise sur le développement africain sera limité à long terme en raison profond conflit d’intérêt entre l’Afrique lié leur excédent...

Résumé Smith a considéré la spécialisation individuelle comme une conséquence négative à subir en matière de développement humain. Cette approche été reprise par le courant marxiste autour du thème l’aliénation. Pour Marshall au contraire, mécanisation l’industrie permet progressivement réduction degré individuelle. Young, l’expansion des systèmes mécanisés est lui-même un processus division travail entre industries et elle devenue principale source rendements croissants. Suivant cette...

Based on the analysis of fluctuations trend man-made board price, this study has carried empirical research to characteristics price using ARCH class models in our country. The showed that: market plywood, fiberboard and particleboard China have significant agglomeration. In addition, main did not show high risk with reward. Therefore, some suggestions stabilize been put forward.

Objective To study the correlation between blood flow parameters by three-dimensional sonography and Nottingham prognostic index (NPI) of breast cancer.Methods A retrospective analysis sonographic image data 89 patients who were pathologically confirmed invasive ductal cancer was made.The technology color power angiography (3D-CPA) used to obtaining vascular (VI),flow (FI) vascular-flow (VFI) before operation.NPI obtained a formula which computed on basis postoperative pathological data.The...
