Effect of Chain Extension on Rheology and Tensile Properties of PHB and PHB-PLA Blends [PDF]
, 2014 RÉSUMÉ: Le poly(3-hydroxybutyrate), ou PHB, est un polymère biodégradable synthétisé par voie bactérienne. L'intérêt porté à ce polymère biodégradable est motivé par ses propriétés mécaniques, qui sont fort similaires à celles du polypropylène, un ...

Bi‐level capacity planning for park IES considering energy supply reliability
Energy Conversion and Economics, EarlyView.Abstract Carbon emissions and energy consumption of urban buildings represent a notable fraction of global energy utilization. In pursuit of the “carbon peaking and carbon neutrality” goals, urban park building integrated energy system (IES) energy saving technology is regarded as a key technology to achieve sustainable urban development.

Monetary Policy, Investor Sentiment and Stock Price Bubble: Evidence From China
Accounting &Finance, EarlyView.ABSTRACT The empirical results indicate that an increase in interest rates may stimulate a significant and persistent stock price bubble, which is consistent with rational asset price bubble theory. This finding suggests that central banks should implement anti‐turbulent monetary policy with caution, since inappropriate tightening may unintentionally ...

Australian Endodontic Journal, EarlyView.ABSTRACT There is a scarcity of data regarding knowledge, attitudes and practices (KAP) of endodontists about cone‐beam computed tomography (CBCT), which may be related to the lack of valid and reliable measures. The present study aimed to develop and validate a KAP measure about CBCT.

Archaeometry, EarlyView.ABSTRACT With northern regions warming at twice the global rate, assessing the state of archaeological sites in these areas is critically important. In this study, we used a multimethod geophysical approach (ERT, GPR, and EMI) to characterize the current geocryological conditions of an Inuit archaeological site on South Aulatsivik Island (Labrador ...

Maternal education and preventive health behavior: Evidence from Cambodia
Asian Economic Journal, EarlyView.Abstract We examine the effect of maternal education on preventive health behavior using data from Cambodia. Given concerns about the endogeneity of education, we employ an instrumental variable (IV) strategy that exploits the variation in the average years of maternal education across provinces and between cohorts that entered primary school following

Preparation and characterization of PHB blended with modified soluble starch
, 2010 碩士本研究利用溶液摻混與熔融摻混法製備生物可分解塑膠聚羥基丁酯與澱粉接枝聚醋酸乙烯酯PHB/PVAc-modified Starch聚掺合體，探討其相容性並測量其性質，因為PHB成本過高，於是藉著摻合同樣具有生物可分解性但價格便宜的澱粉以大幅降低成本。而為了增加澱粉和PHB的相容性，於是將和PHB相容的PVAc接枝到澱粉上，為了增加接枝比值，將硝酸銨鈰起始劑溶解在不同濃度之硝酸溶液中，探討硝酸濃度對單體轉化率，接枝效率和接枝比值的影響。將接枝比值最高(0.223)的改質澱粉(SV3 ...
