The purpose of this paper is to identify the feature of soot in diesel engine oil and provide a method to stably disperse these soots using effect additives which is benefical for lubricants to pass related engine tests.

This paper designed experiments to investigate the dispersant type, treat level and different dispersant interactions which influence on lubricant soot-related viscosity increase. The research work developed an effective dispersant package which can well solve the soot-related viscosity increase, allowing pass Mack T-11 and Mack T-8 engine tests and demonstrated the helpfulness of using a quickly screening method developed by a steel piston diesel engine CA 6DL2-35.

The effect of dispersant treat level on the viscosity increase of the oil samples was negligible. Dispersant booster can effectively improve the soot handling ability of heavy-duty diesel engine oils (HDDEO), and the appropriate treat level of dispersant booster can help HDDEO pass Mack T-8 and Mack T-11 engine tests.

The test results are useful for formulators to select the appropriate dispersants or dispersant booster to develop the HDDEO packages which can meet the modern diesel engine lubrication requirements.

Most previous studies in this field were carried out on soot formation mechanism and soot-related wear rather than how to solve the soot-related viscosity increasing of HDDEO. This paper describes the soot dispersing requirements of different HDDEO specifications and developed an effective dispersant package which can well deal with Mack T-11 and Mack T-8E standard engine tests soot handling ability requirements.

This article was based on the information from The 5th International Conference of Institutes and Libraries for Chinese Overseas Studies held in the University of British Columbia in Vancouver, BC, Canada in which the author was a presenter in session 4.2.9a of the Early life of Yuan Shikai and the formation of Yuan family. The paper aims to include comprehensive analysis and development of the history of Chinese migration. An annotated bibliography of suggested readings was offered to highlight the subject knowledge for further research in this area.

The paper includes comprehensive analysis and development of the history of Chinese migration and the experiences and family histories of overseas Chinese in Canada. An annotated bibliography of suggested readings was offered to highlight the subject knowledge for further research in this area.

The paper offers full description and comprehensive analysis of the history of Chinese migration and overseas Chinese studies in Canada. A bbibliography of suggested readings was offered for further research in this area.

This research study has a strong subject focus on Chinese migration, overseas Chinese studies, and resource-sharing in the subject area. It is a specific field for research in Asian studies.

The result of this study will assist students, researchers, and the general public in the area of overseas Chinese studies and developing their interests in the social and historical value of Chinese migration history and resource-sharing in the area.

Very little research has been done in the area of Chinese migration and historical development. The paper would offer historians, sociologists, ethnologists, librarians, administrations, professors, as well as students in the fields of Asian history, anthropology, sociology, political science, geography, and other Asian-related interdisciplinary studies.

The main purpose of the paper is to examine the truth behind allegations of neo-colonialism performed by China toward Africa, which was raised due to the growing relationship between China and Africa that enhanced the debate between supporters of the notion of neo-colonialism or mutual beneficial relationship. In addition to the growing number of arguments are on the dominance of PRC in Africa over the western powers as European Union or United States in the Continent.

The paper investigates the claims of neo-colonialism practiced by China toward Africa through the lenses of international political economy using the Interdependence theory of neoliberalists. Egypt was selected as a case study due to the emphases that Egypt gives to China as a strategic partner and as rising economic power as well as representing a way of diversifying Egypt's foreign policy and an additional economic partner beside the western ones. The research relied on two interwoven indicators to investigate the main argument: Trade and Development Aid.

The two pillars of analysis indicate that the growing relationship between Egypt and China is a form of interdependent relationship that is expected to get further complex in the future, which is relatively indicated among other things in the synergy Egypt has made between its Vision 2030 and China's Belt and Road Initiative. In reference to development aid, China uses different techniques that is not commonly used by the donors of Official Development Assistance (“ODA”), and due to unpublished actual data on China's aid figures, any indication of dominance is hard to attain regardless a solo incident of debt trap in Africa, the model of China's aid is provided through low-interest loans for development projects that is highly important for developing countries.

The paper tried to engage in the ongoing debate and examine the truth behind the neo-colonial allegations from the perspective of international political economy, which is an added value to the literature in this regard as the data provided are prepared for the present research purpose.
