Save energy, reduce carbon and environmental protection issues are increased concerned in the world. To be a citizen of the world, every enterprise should proceed with environmental management and corporate greening no matter for the purpose of fulfilling the corporate social responsibility or making profits. Become the goal of the origination for the sustainable. Green corporate culture is the foundation of developing green corporate and core of green business model. Therefore we interviewed 5 ompanies which have good performance on the corporate greening, greening innovation, they both have advantage for the corporate. We found the greening culture more longer , then it effect the employee more , and clear found it on the employee behavior, attitude. We found one more interested thing, for the greening innovation, technical guidance corporate, more focus on the greening product than greening process.

Huanglongbing is a citrus disease devastating the worldwide citrus industry. It is caused by the pathogen Candidatus Liberibacter asiaticus (CLas), and spread through the Asian Citrus Psyllid (ACP). ACP vectors HLB as a host for CLas and spreads the bacteria through the saliva when feeding on citrus leaves. There is no cure for the disease, making preventative measures a top priority for the citrus industry. Previously used methods such as individual protective covers and insecticides have proven effective but costly to slow the spread of the disease. In this thesis, we report on the interactions of a novel zinc-borate spray-on material, referred to as Galvoxite. Once sprayed, Galvoxite, will create a protective layer on the leaves impeding the ACP from feeding. This is expected to inhibit the spread of CLas. In this work, we track the location and accumulation of Galvoxite on the leaf surface. It is hypothesized that Galvoxite will create an even film over the entire leaf when sprayed. We blended a fluorescent Ru dye with a long-excited state lifetime into the Galvoxite to determine the specific interactions with the leaf surface. Time Correlated Single Photon Counting (TCSPC) and Fluorescence Lifetime Imaging (FLIM) were used to measure the excited state lifetime of the Galvoxite with the presence of the Ru dye and locate it on the leaf surface. Our data suggests that Galvoxite preferentially accumulates around the stomata, while the Ru dye remains in the regions on the leaf surface between stomata. This was confirmed with energy dispersive X-ray spectroscopy, where zinc-rich regions were found to be adjacent to Ru-rich regions. The results display the potential of Galvoxite being used to hinder ACP from spreading CLas.

Due to the deterioration of the earth’s health and the uncertainty in terms of climate changes, economy, food, water and energy supplies, the above terms have become worldwide phenomena. Buildings have a huge role to play in addressing the environmental concerns as they play a contributing role in gas emissions, waste disposal and energy use. The literature review and results of the quantitative research amongst experts like facility and building managers, leasing agents, finance managers and project managers in the property sector formed the basis of the study. Although green buildings are regarded as the future, the study revealed that there is a perception, even amongst experts in the property sector that the upfront costs of building green is substantially higher when compared to building conventional, which limits the construction of green buildings. This research is aimed at investigating whether building green leads to financial benefits which will ultimately provide the differentiator when it comes down to a final decision whether to invest in green buildings or not. An overview is also provided on the fundamental principles of green buildings which are important to be implemented in the construction of green buildings in order to maximise the financial benefits provided by green buildings. The study showed that experts agreed that the concepts applied in green buildings lead to long-term financial savings which justifies the statement that a realistic comparison between the total costs of building green versus building conventional can only be achieved over the lifecycle of a building. The main finding of this study is that there is awareness and understanding of the financial benefits associated with green buildings which implies that green buildings have a good growth potential. / MBA, North-West University, Potchefstroom Campus, 2014

Save energy, reduce carbon and environmental protection issues are now highly concerned in the world. To be a citizen of the world, every enterprise should proceed with environmental management and corporate greening no matter for the purpose of fulfilling the corporate social responsibility or making profits. Green corporate culture is the foundation of developing green corporate and core of green business modle. Therefore we interviewed 7 companies which have good perfornmance on the corporate greening, to look into what actions they took to promote the green values and change the employees¡¦behaviors in order to set up green corporate culture. We found the stronger the green values of the top management team, the more resources they invested to set up green corporate culture, and the more apparent on the atmosphere of the green corporate culture. Besides, in the aspect of industry difference, the company which is close to downstream value chain, belongs to new development industries, or with more capital, invested more to set up green corporate culture.

The main content of this master´s thesis is Airport Operations Management and it´s application on regional airport Brno – Tuřany. The study analyses common airport operations at the airports and compares it with actual situation at Brno airport. Focusing on comparsion, new upgrading or suggestions for increasing the operations are made. The part of thesis encloses also an approach to contemporary issues in greening the airports and air traffic.

Since the adoption of neoliberalism, many cities have taken to integrating nature with capital accumulation to create a sense of place. This has been closely tied to urban greening, or green "revitalization." As part of curating this desired character, city governments are working to roll out plans to restore and renew neighborhoods using their natural landscapes through methods such as reforestation, the creation of parks, and commercial development. These cities, deemed Entrepreneurial cities, are increasingly incorporating natural or green spaces into their development of character as part of their branding schemes. This research focuses on the role of nature as the site of economic development and community revitalization within Dallas, Texas. This research examines how the City of Dallas uses nature to attract capital, and how the narratives of development relate to residents' visions for development in the historically neglected Joppa neighborhood in the Trinity River Corridor. Development near Joppa could be an example of how the natural landscape is being used to not only attract developers but also to bring a different ‘class' of resident into the area. By exploring this intersection of nature and capital in Dallas, we can better understand the nuanced ways through which the neoliberalization of nature can lead to deeper social and economic disparities.

O greening ou Huanglongbing (HLB) é uma das mais graves doenças dos citros presentes nos pomares do Brasil. Causada pela bactéria Candidatus Liberibacter spp, é transmitida pelo inseto psilídeo Diaphorina citri, que ao se alimentar de uma planta doente transmite a doença às demais plantas. O greening apresenta como sintoma, manchas amareladas nas folhas, muitas vezes confundidas com deficiências nutricionais. A erradicação da planta e o controle do inseto transmissor são as únicas formas de prevenção para evitar a sua propagação. Este trabalho teve por objetivo avaliar uma metodologia baseada em segmentação por cor e outra baseada em análise de textura para avaliação de folhas de citros sintomáticas, identificando se estão contaminadas com o greening ou outras doenças e deficiências nutricionais. Foram fornecidas pelo grupo FISHER, 324 amostras de folhas cítricas, contendo folhas com doenças (greening, CVC e rubelose) e deficiências nutricionais (manganês, magnésio e zinco). As folhas foram digitalizadas por um scanner de mesa, com duas resoluções, utilizando somente a parte frontal da folha. Foram montados três bancos de imagens. Os resultados gerados com a metodologia baseada em segmentação por cor utilizando RNA PMC, mostraram que essa metodologia não é eficiente. Na metodologia baseada na análise por textura foram avaliados os descritores LBP, LFP e os de Haralick. Para estes descritores foram extraídas amostras por folha e por quadrantes das folhas nos canais de cores vermelho e verde e amostras em níveis de cinza. Os resultados gerados pelos descritores foram classificados pela distância &#9672 e pelos algoritmos IBK e RNA PMC do toolbox Weka. Os melhores resultados foram para os descritores LBP e LFP-s para distância &#9672, com valores de sensibilidade acima de 97% e 93%, respectivamente, e para o LBP com o algoritmo IBK, com valores de sensibilidade acima de 98,5%. Os resultados obtidos evidenciam que o descritor LBP é o mais eficiente seguido pelo LFP-s na diferenciação do greening das outras pragas. / The greening or Huanglongbing (HLB) is one of the most serious diseases of citrus orchards present in Brazil. HLB is caused by the bacterium Candidatus Liberibacter spp, it is transmitted by the psyllid insect (Diaphorina citri) that, when feeding on a diseased plant, it transmits the disease to other plants. One of the symptoms of the greening are yellowish spots on the leaves, often confused with nutritional deficiencies. The eradication of plants and control of insect are the only forms of prevention. This work aims to evaluate two methodologies: one based on color segmentation and the other based on texture analysis for assessment of symptomatic citrus leaves, identifying whether they are infected with greening and other diseases and nutritional deficiencies. A number of 324 samples of citrus leaves were provided by FISHER group, infected with diseases (greening, CVC, rubelose) and nutritional deficiencies ( manganese, magnesium, zinc) . The leaves were acquired by a flatbed scanner with two different resolutions, using only the front side of the leaf. Three datasets of images were constructed. The results generated using the methodology based on color segmentation with ANN MLP, showed that this methodology is not efficient. In the methodology based on texture analysis it was evaluated the LBP, LFP and the Haralick descriptors. For these descriptors it was extracted samples from the leaves and quadrants of leaves, in red and green color channels and grayscale. The results generated by the descriptors were classified by &#9672 distance and the algorithms IBK and ANN MLP from the toolbox Weka. The best results were for LBP descriptor and LFP-s for &#9672 distance with values of sensitivity above 97% and 93%, respectively, and the LBP with IBK algorithm, with values of sensitivity above 98.5%. The results showed that the LBP descriptor is the most efficient followed by LFP-s in the differentiation of the greening from other pests.
