China’s Challenging the “Ricardo Law” Circle： Is world development inevitably antagonistic or conflictive

World historical development, especially the development of modern and contemporary globalization, tends to be antagonistic, conflictive and non-harmonious. Its theoretical demonstration is “Ricardo Law” circle, namely the rule that social productivity development and historical progress are at the expense of certain social classes and strata. Western countries after the Second World War have hence changed partly in certain ideas, productivity and specific regulations. Will China be fettered by “Ricardo Law” circle in our transformational socialism and has to apply the antagonistic, conflictive and non-harmonious method to achieve the alienating “development”? This paper analyzes the harmony and conflict thoughts and policies of the western economics represented by “Ricardo Law” in order to probe into our socialist social and economic harmony theory. Key words: Ricardo Law, harmony and conflict thoughts of western economics, Harmonious Society Theory Résumé: Le développement historique du monde, notamment le développement de la globalisation moderne et contemporaine, tend à s’avérer antagoniste, conflictuel et non harmonieux. La démonstration théorique est le cercle de la « loi de Ricardo », à savoir la règle que le développement de la force productive sociale et le progrès social sont aux dépens de certaines classes et souches sociales. Après le Seconde guerre mondiale, les pays occidentaux ont changé en partie certaines idées et des régulations spécifiques. Est-ce que la Chine sera enchaînée par la loi de Ricardo dans notre socialisme transformationnel et aura à appliquer la méthode antagoniste, conflictuelle et non harmonieuse pour accomplir le développement aliéné ? Le présent article analyse les pensées et politiques d’harmonie et de conflit des pays occidentaux, représentées par la loi de Ricardo, dans le but d’explorer la théorie d’harmonie économique et sociale socialiste de notre pays. Mots-Clés: loi de Ricardo, pensées d’harmonie et de conflit des pays occidentaux, théorie de la société harmonieus

An optical fiber tip micrograting thermometer

An ~12 µm long Bragg grating was engraved in an ~5 µm diameter optical fiber tip by focused ion beam (FIB) milling. An ~10-dB extinction was achieved at 1570 nm with only 11 indentations. The grating was used for temperature sensing, and it exhibited a temperature sensitivity of ~22 pm/°C

Approaches to the Total Synthesis of Puupehenone-Type Marine Natural Products

Puupehenones have been isolated from the marine sponge Chondrosia chucalla, which belong to a growing family of natural products with more than 100 members. These marine natural products have attracted increasing attention mainly due to their wide variety of biological activities such as antitumor, antiviral, and anti-HIV, and thus offer promising opportunities for new drug development. This chapter covers the approaches to the total synthesis of puupehenone-type marine natural products including puupehenol, puupehenone, puupehedione, and halopuupehenones. The routes begin with the construction of their basic skeletons, followed by the modification of their C- and D-rings. The contents are divided into two sections in terms of the key strategies employed to construct the basic skeleton. One is the convergent synthesis route with two synthons coupled by nucleophilic or electrophilic reaction, and the other is the linear synthesis route with polyene series cyclization as a key reaction

Genome-Wide Association Mapping for Tomato Volatiles Positively Contributing to Tomato Flavor

Tomato volatiles, mainly derived from essential nutrients and health-promoting precursors, affect tomato flavor. Taste volatiles present a major challenge for flavor improvement and quality breeding. In this study, we performed genome-wide association studies (GWAS) to investigate potential chromosome regions associated with the tomato flavor volatiles. We observed significant variation (1200x) among the selected 28 most important volatiles in tomato based on their concentration and odor threshold importance across our sampled accessions. Using 174 tomato accessions, GWAS identified 125 significant associations (P<0.005) among 182 SSR markers and 28 volatiles (27 volatiles with at least one significant association). Several significant associations were co-localized in previously identified quantitative trait loci (QTL). This result provides new potential candidate loci affecting the metabolism of several volatiles

Comparison between anterolateral thigh perforator free flaps and pectoralis major pedicled flap for reconstruction in oral cancer patients-A quality of life analysis

The aim of this study was to compare the differences between anterolateral thigh perforator free flaps (ALTFF) and pectoralis major myocutaneous flap (PMMF) for reconstruction in oral cancer patients. Method and Patients: who received free flap or PMMF reconstruction after ablation surgeries were eligible for the current study. The patients' demographic data, medical history, and quality of life scores(Medical Outcomes Study-Short Form-36 (MOS SF-36) and the University of Washington Quality of Life (UW-QOL) questionnaires were collected. Results: 81 of 118 questionnaires were returned (68.64%). There was signi.cant differences between two groups in the gender (P<0.005). Patients reconstructed with ALTFF had better appearance domains and better shoulders domains, in addition to better role emotion domains. Conclusions: Using either PMMF or ALTFF for reconstruction of oral defects after cancer resection signi.cantly in.uences a patient's quality of life. Data from this study provide useful information for physicians and patients during their discussion of reconstruction modalities for oral cancers
