The islands are mainly formed from carbonate (limestone), intrusive igneous rock, sedimentary and volcanic rocks, in which limestone islands predominate, distributed mainly in the Gulf of Tonkin. This paper presents the results of researches and assessments on sea water quality of Vietnam's typical limestone islands and archipelagoes through the 2017-2018 surveys. The research results show that although the water quality around of limestone and archipelago area of Vietnam is safety for the development of aquatic life, an increase in pollutants concentration in water has been recorded when compared to previous research results. The research results supplement the data set of sea water quality in limestone areas that defining the characteristics of marine biodiversity. Keywords: limestone island, water quality, pollutants. 1. Introduction only 2% of the quantity and 0.83% of area. The South Central Coast and the South Coast have Vietnam has about 2773 coastal islands with the same number of islands (about 7%) but in an area of 1721km2 but they distribute very terms of area, the southern coastal islands are different in the coastal waters.

  • Local Rule of Đại Việt Under the Lý Dynasty: Evolution of a Charter Polity After the Tang-Song Transition in East Asia
    Asian Review of World Histories 1:1 (January 2013), 45-84 © 2013 The Asian Association of World Historians doi: http://dx.doi.org/10.12773/arwh.2013.1.1.045 Local Rule of Đại Việt under the Lý Dynasty: Evolution of a Charter Polity after the Tang-Song Transition in East Asia MOMOKI Shiro Osaka University Osaka, Japan [email protected] Abstract Empirical research into Đại Việt before the 14th century has made little pro- gress since the 1990s. To improve this situation, I here examine how the Lý dynasty (1009-1226), the first long-lasting dynasty of Đại Việt, established stable local ruleafter the “Tang-Song Transition” in China that changed the entire picture of East Asia (including both Southeast and Northeast Asia). This paper focuses on two issues. First are the local administrative units and their governors. The nature of both higher units like lộ (circuits), phủ and châu (provinces), and basic units like hương and giáp (districts?) will be examined. Second, I examine non-institutional channels of local rule by the imperial family. By combining such administrative and non-administrative means, the Lý central court enforced a considerably stable local rule for two centuries. Finally, I attempt some preliminary comparisons with the local rule of Goryeo (918-1392) in the Korean peninsula, a polity that shared many features with Đại Việt in the process of localization of the Tang and Song models. I hope this approach of viewing small empires from the standpoint not of their “goal” (modern states) but of their “start” (charter polities), will enrich the discussion of East Asian small empires.

The thesis examines how HPWSCo tackled the typical problems of a developing country's municipal water supply company and succeeded in the eyes of the consumers, the local and national governments, and the wider development community. The thesis describes how and under what conditions HPWSCo has changed itself from a poorly performing utility to a successful one.

It is home to many ethnic minorities with rich and unique traditional cultural values. During the development process, especially in the renovation years, ethnic minorities in the Northeastern provinces have united, attached and jointly developed socio-economic, hunger eradication and poverty alleviation, create livelihoods, step by step create positive changes in all aspects of social life. Despite many advantages, the Northeastern provinces are still one of the poorest regions compared to other regions in the whole country. In the past years, our Party and State have promulgated many guidelines and policies prioritizing socio-economic development in ethnic minority area in general and the Northeastern region in particular. As a result, the socio-economic in the Northeastern mountainous region has achieved important results. However, in the development process, many problems have arisen in the socio-economic field, directly affecting the poverty reduction for ethnic minorities in the Northeastern region. Therefore, in the coming time, it is necessary to have appropriate and timely solutions to promote sustainable economic development in this region so that the Northeastern region can be fully integrated into the world economy.

  • Ontogeny of Positional Behavior in Captive Silvered Langurs (Trachypithecus Cristatus)
    Ontogeny of Positional Behavior in Captive Silvered Langurs (Trachypithecus cristatus) A Senior Honors Thesis Presented in Partial Fulfillment of the Requirements for graduation with research distinction in Anthropological Science in the undergraduate colleges of The Ohio State University by Amy Eakins The Ohio State University March 2010 Project Advisor: Professor W. Scott McGraw, Department of Anthropology ABSTRACT Compared to most other mammalian groups, primates are known for the great diversity of positional behavior they exhibit. Their positional repertoire is not static through time, but rather changes with age. As primates age and body size increases, the manner in which animals navigate their environment responds to shifting biomechanical, nutritional, socio-behavioral and reproductive factors. In this study, I examined positional behavior in a colony of captive colobine monkeys, hypothesizing that locomotor and postural diversity will increase with age due to changing physiological and ecological processes. I predicted that as animals mature, their positional diversity will increase as they become more adept at negotiating their three- dimensional environments. I examined age effects on positional behavior in silvered langurs (Trachypithecus cristatus) housed at the Columbus Zoo. Data were collected from January – August 2009 using instantaneous focal animal sampling on a breeding group containing four adults, two juveniles, and one infant. During each scan I recorded the focal animal’s identity, maintenance activity, substrate, and postural (19 categories) or locomotor (12 categories) behavior. Chi-square tests were performed on the data set of 4504 scans. Contrary to expectations, my analyses show that the number of observed positional behaviors did not change significantly with age, although the types of behaviors observed did change.

    Vietnamese Journal of Primatology (2010) 4, 57-68 The Pedicinus species (Insecta, Phthiraptera, Anoplura, Pedicinidae) on douc langurs (Pygathrix spp.) Eberhard Mey Museum of Natural History at the State Museum Heidecksburg, Schloßbezirk 1, D-07407 Rudolstadt, Germany. <[email protected]> Key words: Pygathrix spp., lice, Pedicinus, new species, Vietnam Summary All three species of Southeast-Asian douc langurs (Pygathrix spp.) harbor a host-specific species of Pedicinus (Neopedicinus). Using freshly collected material of known provenance, these were identified as Pedicinus tongkinensis Mey, 1994 ex Pygathrix nemaeus, Pedicinus atratulus nov. spec. ex Pygathrix nigripes, and Pedicinus curtipenitus nov. spec. ex Pygathrix cinerea. The three species described here are closely related to each other and belong to the newly created “ancoratus species group” within the subgenus Neopedicinus. Loài Pedicinus (Insecta, Phthiraptera, Anoplura, Pedicinidae) trên các loài Chà vá (Pygathrix spp.) ở Đông Nam Á Tóm tắt Cả ba loài chà vá (Pygathrix spp.) của Đông Nam Á là nơi trú ngụ của một loài ký sinh Pedicinus (Neopedicinus). Sử dụng vật liệu được thu thập tươi từ nguồn gốc đã biết, các loài này được xác định là Pedicinus tongkinensis Mey, 1994 ex Pygathrix nemaeus, Pedicinus atratulus nov. spec. ex Pygathrix nigripes, và Pedicinus curtipenitus nov. spec. ex Pygathrix cinerea. Ba loài được mô tả ở đây có quan hệ gần gũi với nhau và thuộc về “nhóm loài ancoratus” mới được tạo ra trong giống phụ Neopedicinus. Introduction The colobine genus of the douc langurs Pygathrix E. Geoffroy St.-Hilaire, 1812 is endemic to Indochina. Three monotypic species are distinguished (Roos & Nadler, 2001, Nadler et al., 2003, Nadler, 2007).
