Firstly, more than 50 efficient crude oil-degrading and biosurfactant producing bacteria were isolated from petroleum-contaminated soil and water in Tianjin Binhai New Area Oil field, China. Twenty-four of them were selected for further study. These strains were identified as belonging Pseudornonas aeruginosa, Bacillus subtilis, Brevibacillus brevis, Achrornobacter sp., Acinetobacter venetianus, Lysinibacillus rnacroides, Klebsiella oxytoca, Stenotrophornonas rhizophila, Rhodococcus sp. and Bacillus thuringiensis. A shake-flask degradation test revealed that 12 of these strains could degrade over 50% of 1% crude oil concentration in 7 d. Of these, 8 strains were able to produce biosurfactants. Furthermore, environmental tolerance experiments indicated that the majority of the strains had the ability to adapt to extreme environments including high temperatures, alkaline en- vironments and high salinity environments. A mixed bacterial agent comprising the strains WB2, W2, W3 and HA was developed based on the environmental tolerance tests and subjected to the pilot-scale degradation test indicating that this bacterial agent could degrade 85.2% of 0.8% crude oil concentration in 60 d. Our results suggest that the application of this mixed agent could remediate crude oil polluted soils in saline and alkaline environments.展开更多

Within space missions, above all those involving rovers that have to explore planetary surfaces, vision can play a key role in the improvement of autonomous navigation functionalities: besides obstacle avoidance and hazard detection along the traveling, vision can in fact provide accurate motion estimation in order to constantly monitor all paths executed by the rover. The present work basically regards the development of an effective visual odometry system, focusing as much as possible on issues such as continuous operating mode, system speed and reliability.展开更多

At the same time we will have to face severe environmental issues in the future. This is evident in forming the elements of earth, air, and water which reflect the human influence on organic and inorganic life. So, it is timely significant to pay attention on environmental preservation and management. The main purpose of this study is to explore how the Buddhist teaching could be used for environmental preservation and management. Accordingly, this study introduces a suitable long term environmental preservation model. The other objectives of this study are to learn Buddhism for environmental preservation and management, to create a new model which combines man and environment together, to compare Buddhist thinking and modem man's thinking regarding environmental preservation and management through the above and, to motivate man to preserve environment in through both direct and indirect ways. This study was based on the question whether the Buddhist philosophical teaching could be utilized to solve today's environmental issues? The hypothesis was that the Buddhist philosophical teaching could be utilized for environmental preservation and management. For this purpose, the teachings of Buddha, related to environmental preservation as found in "Suttapil;aka" and "Vinayapi!;aka" were studied. In order to address these conditions we have subjected randomly collected information for interpretation and comparative analysis in qualitative research methodology. The content that has been analyzed is compared with the ethical code related to the patterns of human behavior and its relation to conservation. This has also given way to building some models related to the Buddhist teaching of environmental preservation. The objective of Buddhist philosophy is to generate sensitivity in the mind, of human beings and persuade them to preserve organic and inorganic environment, based on the view "Man is a creation of the environment". The Buddhist philosophical process of environmental preservation includes preserving flora and fauna, water, air, soil as well as garbage disposal. These elements, along with ethics, can be used in effective environment preservation. This new model of environmental preservation directs human beings towards sustainable development with a realistic vision. The Buddhist teaching on environment civilizes man's physical and spiritual behaviors, with a view to lead human beings towards environmental preservation with a realistic perspective.展开更多

The need for housing and housing space quality can therefore not be overemphasized. The need for housing remains a constant index for all societies through the ages. Housing is a complex and heterogeneous product in its setting, the cognitive structures of housing users for housing attributes is also complex as well as their choice behaviors. Means-End Chain (MEC) model has been found to be very effective and potent in measuring these complexities. This conceptual paper explores from literature the MEC model and attempts to propagate its use as a research model for housing research, environment-behavior studies and person-environment congruence. It also presents the methodology employed by MEC for data collection and data management. It will suggest an extension to the traditional methodology that MEC utilizes. The possibility of extending the previous methods and their applicability in design process is herein presented; and to make a case for the usability of MEC model as a research tool for housing researchers. In dealing with user preference of housing, there is a need for research for a development of a technological tool for the identification of user needs and preference, and the kind of decision support that are required to identify these needs.展开更多

These bonds often place both internal and external limitations that apparently create the view that a human being has no free will but is determined. This paper explores the controversial issue whether a human being possesses free will to make free choices or is determined. It is the stance of this study that if one does not have free will then one cannot be morally responsible for one's actions and consequently praise and blame would then have no value. The paper, therefore, is of the view that notwithstanding the many bonds within which they live, humans, with their special dignity, have free will that operate within the respective constraints set by the bonds of human life. Furthermore, since morality involves good and bad, the paper asserts that for an act to be designated as morally good or bad, it implies that the agent was free to perform the said act or do otherwise to merit praise or blame respectively. Thus, for human freedom to be significant, it must be responsible.展开更多

Unfortunately, these campaigns do not always lead to the upgrading of people's pro-environmental behaviors, because people's behaviors are usually based on various motivations, including economic efficiency, convenience and so on. This article mainly aimed at analyzing the implementing reasons of people's pro-environmental behaviors and finding out policies of promoting people's pro-environmental behaviors. Therefore, the author conducted the internet investigations among male and female respondents over 20 years old, and collected valid responses of more than 1,000 from 2008 till 2014 every year in Japan and also used three communication concepts, which are the direct communication, the indirect communication and the direct and indirect combined communication as a framework for discussing policies of promoting people's pro-environmental behaviors. As a result of the internet investigations, it was found that non-environmental factors, such as "saving the household", "compliance with social norms" and "health" were bigger than the environmental factors, such as "the prevention of the global warming" and "saving resources" with regard to the implementing reasons of the pro-environmental activities. Actually, the pro-environmental activities often have the non-environmental benefits, such as cost-saving, health and so on. And so, the author suggests that it is effective that upgrading the implementation rate of the pro-environmental activities do not only appeal to the effects of reducing the environmental loading that the activity has (the direct communication), but also to the non-environmental benefits that the activity has, especially it is true to unconcerned people about environmental issues (the indirect communication). In addition, the author emphases that people need to appeal to both the environmental effects and the non-environmental benefits which the activity has, respectively, especially to people with the concern about environmental issues to some extent (the direct and indirect combined communication).展开更多

A kind of bionic flexible body is presented for quadruped robot to perform the spinning gait. The spinning gait can be achieved by coordinated movement of body laterally bending and legs swing,which can improve the mobility of robot walking in the unstructured environments. The coordinated movement relationship between the body and the leg mechanism is presented. The stability of quadruped robot with spinning gait is analyzed based on the center of gravity( COG) projection method. The effect of different body bending angle on the stability of quadruped robot with spinning gait is mainly studied. For the quadruped robot walking with spinning gait,during one spinning gait cycle,the supporting polygon and the trajectory of COG projection point under different body bending angle are calculated. Finally,the stability margin of quadruped robot with spinning gait under different body bending angle is determined,which can be used to evaluate reasonableness of spinning gait parameters.展开更多

Such prejudices manifest in diverse behavioural and relational manners that either peripheralize the woman or out-rightly remove every vestige of human dignity from her being. Language, being a significant carrier of our emotions, biases, beliefs, preference and prejudices, provides a crucial platform for the interrogation of the nature of gender relations and their consequences in any society, such consideration has forced a preponderance of scholarly interest in gender studies in arts and humanities. This study caries out a scholarly investigate into such gender inspired biases through the prison of Yoruba proverbs as a reflection of our cultural practices and beliefs about the position of the woman in a typical traditional Yoruba setting展开更多

These slums represent a fertile environment for diseases caused by pollution in all its forms and are subject to crimes, rape and theft. There is a huge difference in the state of conditions when comparing the formally planned areas to the informally planned ones. People living in the formally planned settlements, like Nasr City, and in informal ones, like Ezbet El-Haggana, are similar to the kings and queens and slaves of legends. This paper tries to find solutions to the problem of slums and random areas.展开更多
