Starch is an essential but very complex semi-crystalline biopolymer. In addition to being an important food source, numerous industrial applications have been proposed for this renewable material. Most applications are highly dependent on the physical properties of the material which are a strong function of the amount of intra- and inter-molecular interactions. This research investigates the potential to manipulate the type and amount of chain-chain interactions to tailor the properties of starch for different applications. Three types of additives acting as probe molecules were used to vary these interactions by changing the amounts and the pH of each sample: a very polar organic molecule, glycerol, a high electron density compound, TiO2, and a mostly hydrophobic organic molecule, cholesterol. Differential scanning calorimetry was used to determine the strength and the amount of chain-chain interactions while Fourier transform infrared spectroscopy was used to follow the nature of these interactions. Results show that the different probe molecules do interact with starch but form chemical interactions at different locations on the chain. We conclude that with proper play on amount, type of additive, temperature cycle, and pH a composite of starch could be tailored for numerous and specific applications.

The increase of inter-boundary transactions brings a number of benefits for enterprises. However, even when benefits of transfer pricing are evident, multinational organizations still face legal challenges, including performing parts of transactions in another jurisdiction and motives of tax officials in investigating transfer pricing. This is especially true when countries do not want to lose benefits from tax collection. Therefore, many countries and organizations such as the Organization for Economic Cooperation and Development （OECD）, Pacific Association of Tax Administrators （PATA）, the European Union （EU）, and Vietnam have introduced requirements for transfer pricing documentation to prevent transfer pricing manipulation and maintain benefits from taxes. The aim of this research was to assess the compliance of those requirements of foreign direct investment （FDI） enterprises in Vietnam. This article which is a summary of our research includes the following sections：（1） OECD guidelines of transfer pricing documentation; （2） Vietnam regulations of transfer pricing documentation; （3） results of the research; and （4） discussion and conclusion.

This article presents the results of dividing the hydrogeological structure zones in aquifer of Cai Phan Rang river basin, Ninh Thuan province, Viet Nam, and the relationship between parameters of hydrogeological structure zones with water storage capacity of hydrogeological structure. Research results divided hydrogeological structure of Cai Phan Rang River Basin into four zones, including three zones with depression bedrock and one zone with slope bedrock, and the results assessed：（1） specific discharge of exploitation well is proportional to zone area of hydrogeological structure; （2） specific discharge of exploitation well is inversely proportional to slope of bedrock surface, slope of water level in zone and area of drainage surface of hydrogeological structure zone; （3） water level fluctuation in zone is proportional to slope of bedrock surface, slope of water level in zone and inversely proportional to distribution area of zone; （4） total mineralization of water is proportional to bedrock surface slope and water level slope in zone, and inversely proportional to drainage surface area of zone and volume of structural depression. Research results are practical significance in solutions proposal to increase exploitation capacity for various water use purposes.
