Abstract: Angara flora is an important part of Carboniferous and Permian fossil plants in northern China and has been found mainly in the border provinces and regions of northern China with a roughly E_W extension.Its geographic range includes northern Xinjiang, northern Gansu, northern Ningxia, the Beishan and Badain Jaran areas in west and the Abga Qi, Dong Ujimqin Qi areas in east of Nei Mongol plateu,to east the Da Xingan Ling and Xiao Xingan Ling ranges,and the Zhangguangcai Ling, Wandashan and Laoyieling ranges of Changbaishan Mountains. So far as the knowledge goes, the south limit of the distribution of Angara folra in China is roughly a line from the Telasi river in west to Xingxingxia in east of Xinjiang, eastward through Alxa, Yinshan, Onder Sum, Xar Moron river of Nei Mongol to Songhuahu lake and Yanji city of Jilin,and some late Permian elements of Angara flora have been found in farther south.In geological age,Angara flora in China is ranging from Early Carboniferous to Late Permian as in Angaraland.The Early and Middle Carboniferous ones are mainly distributed in northern Xinjiang, where the Early_Middle Carboniferous strata are widespread with compex sedimental enviromment of marine, continantal and paralic facies, and yielding abundant animal and plant fossils. The Late Carboniferous ones are widespread over the region in thewest, middle and east parts, where there is a large area terrestrial strata.The Early Permian fossil plants ane poor, though they have been found in the west and east parts of the region, with collections of notmany individuals and relatively monotonous taxa. In Late Permian, Angara flora is most flourishing in this region and occurring almost everywhere in this region.
Theorizing Social Capital in Entrepreneurship—An Empirical Study in the Pearl River Delta, China  [PDF]
Chiu-Yin Leung, Jiang Xu
Chinese Studies (ChnStd) , 2012, DOI: 10.4236/chnstd.2012.13003
Abstract: In this paper, a social capital framework is brought in to explore the dynamics of Chinese entrepreneurship with respect to the social and institutional conditions in the post-reform China. Based on data collected from field interviews, it analyzes how enterprise social capital impacts upon the Hong Kong affiliated manufacturing operations in the Pearl River Delta region. In regard to the “embeddedness-accessi- bility-use” framework, it is suggested that some trivial difference in the configuration of “guanxi (關係)” network could work specifically upon the divergent path of individual entrepreneurs during the early reform period of the Pearl River Delta. As China enters another stage of marketization, firms that have been over-embedded and poorly-positioned in the network are now forcing their way out of the region. Alternatively, recent institutional development across the border has boosted the significance of nurturing enterprise social capital in the formal coordinating channels. The renewal in the stock of enterprise social capital is crucial in reconfiguring the network dynamics and entrepreneurial action to influence the future trajectory of industrial development in the Pearl River Delta.
THE EFFICACY OF EXPERIMENTAL ANGARA DISEASE VACCINES
K. Ahmad and S. Hasan
Pakistan Veterinary Journal , 2004,
Abstract: Formalinized aqua based liver organ vaccines for Angara disease (AD)/hydropericardium-hepatitis syndrome (HHS) are effective for the control of the disease. The experimental formalinized 10, 7.5 and 5% liver organ vaccines showed significant differences in efficacy from 2.5 and 1% liver organ vaccines. However, 10, 7.5 and 5% liver organ vaccines differed non significantly from one another. The vaccines of 10 and 7.5% liver organ concentrations showed the best results in terms of reducing mortality among the given groups, while 5% liver organ vaccine proved the best in both efficacy and economy. The vaccination of AD showed positive effect on the immune response of the chicks against Newcastle disease virus.

Applied Water Science , 2011, DOI: 10.1007/s13201-011-0011-4
Abstract: River Yamuna, in the national capital territory (NCT), commonly called Delhi (India), has been subjected to immense degradation and pollution due to the huge amount of domestic wastewater entering the river. Despite the persistent efforts in the form of the Yamuna Action Plan phase I and II (YAP) (since 1993 to date), the river quality in NCT has not improved. The restoration of river water quality has been a major challenge to the environmental managers. In the present paper, water quality index (WQI) was estimated for the River Yamuna within the NCT to study the aftereffects of the projects implemented during YAP I and II. The study was directed toward the use of WQI to describe the level of pollution in the river for a period of 10 years (2000–2009). The study also identifies the critical pollutants affecting the river water quality during its course through the city. The indices have been computed for pre-monsoon, monsoon and post-monsoon season at four locations, namely Palla, ODRB, Nizamuddin and Okhla in the river. It was found that the water quality ranged from good to marginal category at Palla and fell under poor category at all other locations. BOD, DO, total and fecal coliforms and free ammonia were found to be critical parameters for the stretch.
Human Capital Dimensions in an Emerging Tourism Market: The Case Study of Cross River State, Nigeria

International Business Management , 2012,
Abstract: The purpose of this study was to investigate the human capital dimensions of an emerging tourism market in Cross River State, Nigeria. A stratified sample of 80 tourism firms was randomly selected and a self administered structured questionnaire was employed to collate data. The study revealed that tourism managers were broad-minded in the setting of human capital objectives in their firms. Employment of educationally qualified and trained people did not show significant relationship with customers’ satisfaction and profitability. Experience of employee prior to engagement and payment of competitive salary were significantly related with customers’ satisfaction and firm profitability. The study recommended that a formal tourism education system, to be driven by academic and tourist researchers, should be established in the region.
Social capital, community-based governance and resilience in an African artisanal river fishery
BA Nkhata, CM Breen, A Abacar
Water SA , 2009,
Abstract: This is a study of a community-based fishery on the Rovuma River that forms the border between Mozambique and Tanzania. We postulate a relationship between social capital and community-based governance over access to and the use of the fish resource. In historical times social capital was high and community-based governance regulated access to and use of the fishery as a common property resource. Transforming forces particularly colonial administration, advocating Christianity, war and an emerging market economy undermined social capital, which in turn affected community-based governance. The deconstruction of social capital has resulted in attitudes and behaviours that challenge governance processes with dire consequences for sustainable resource utilisation. Harvesting of fish stocks occurs at levels that are no longer sustainable and inappropriate practices are being adopted. While the Mozambique government policy promotes community-based fisheries management in artisanal fisheries, we argue that under current conditions of ineffective community-based governance, a strong focus on reconstruction of social capital will be required before a community-based resource management process can be effectively implemented. The findings are discussed in the context of resilience in social ecological systems. We suggest that given the historical context in which community-based natural resource management is promoted within southern Africa such a focus may have wide relevance.

Masood Akhtar,Rehan Ahmed,C. S. Hayat,I. Hussain
Pakistan Journal of Biological Sciences , 2000,
Abstract: Immune response of formalin inactivated and binnary ethyleneimine inactivated Angara disease (hydropericardium) vaccines were compared using indirect hemagglutination (IHA) test. A four fold increase in IHA antibody titre was recorded with binnary ethyleneimine (BEI) inactivated vaccine. Agar gel diffusion test gave a strong precipitation line with serum of chicks vaccinated with BEI inactivated vaccine whereas a weak precipitation line was observed with serum from chicks vaccinated with formalin inactivated vaccine. The results of challenge test were promising and no adverse effects were seen in vaccinated chicks. BEI as inactivating agent produced antigenically superior vaccine.
Multitemporal Satellite Images for Knowledge of the Assyrian Capital Cities and for Monitoring Landscape Transformations in the Upper Course of Tigris River  [PDF]

International Journal of Geophysics , 2011, DOI: 10.1155/2011/917306
Abstract: The paper is concerned with the contribution that a rich documentation of multitemporal optical satellite images with high resolution provides for the knowledge of the five great Assyrian capital cities (Ashur, Kar-Tukulti-Ninurta, Kalhu, Dur-Sharrukin, and Nineveh, in northern Iraq). These images also allow monitoring changes of landscape in the higher course of the Tigris during the last half century and document damages in archaeological sites during the two Gulf Wars. The data set, available for each city, consists of panchromatic and multispectral images taken between 2001 and 2007 by modern commercial satellites (Ikonos-2, QuickBird-2, and WorldView-1) and of panchromatic photographs of U.S. spy satellites operating between 1965 and 1969 (Corona KH-4B and Gambit KH-7). These photos were taken before diffusion of mechanized agriculture and the expansion of urban areas, so they are very useful to document many archaeological features and the landscape that has been modified in the last decades, as shown by recent satellite images.
