Phytoremediation Potential of Selected Hydrophytes for Fluoride in Aquatic Environment
by Mamta Baunthiyal, Vinay Sharma
Abstract: Phytoremediation with aquatic plants could be an effective and economic method for improving water quality. The effectiveness of three aquatic macrophytes, viz. Hydrilla verticillata, Chara corallina and Cladophora glomerata were evaluated for their capability to remove fluoride from fluoride contaminated solutions. Different concentrations (10, 20, 50 mgL-1) of fluoride solution were taken in 1 litre plastic container having 20 g macrophytes and 500 ml fluoride solution for 10 days. Chara corallina showed better removal efficiency than other experimental macrophytes. The accumulation of fluoride of more than 1000 mgL-1 in plant tissues indicate that aquatic plants can be considered as hyperaccumulators of fluoride. Significant removal of fluoride was obtained for containers containing all aquatic plants, indicating that they can be utilized in the phytoremediation method to remove fluoride from wastewater.
Keywords: Hyperaccumulation; Fluoride; Hydrilla verticillata; Chara corallina; Cladophora glomerata; phytoremediation.
A review of the current situation, challenges and opportunities in the financial analysis of Enterprise Architectures
by Yeimi Pena, Dario Correal, Eduardo Miranda
Abstract: Enterprise Architecture (EA) has gained increasing recognition from industry and academia because of the support it provides for alignment of business and technology. To achieve this alignment, an EA responds to business concerns with technology solutions based on transition architectures. Both require support from financial analysis. Various researchers and practitioners have developed financial analysis approaches, but most i) use poorly standardized concepts, ii) ignore rapidly changing technology and iii) use limited procedures for financial analyses. This review provides specific information about the current situation of financial analysis available for EA, describes approaches found in a literature review, and proposes challenges and future research directions.
Keywords: financial analysis; enterprise architecture; transition plan; technology investment; methodologies; methods; systematic literature review.

A review of the econometric evidence on innovation policy instruments in Brazil
by Carlos Kawamoto, Paulo Feldmann, James Wright
Abstract: Evaluations of innovation policy instruments have shown a proliferation in growth in the last decade in Brazil ever since the publication of PINTEC, a crucial survey conducted by the Brazilian Institute of Geography and Statistics (IBGE). The sometimes contradictory results among some studies require the development of a clearer picture of the policy effects of R&D in the country. We focus on the additionality effect of inputs from various government incentives, and survey the related empirical literature dedicated to Brazil. Our results suggest that fiscal incentives for R&D activities provide a more robust additionality effect, in comparison to non-reimbursable subsidies for innovative activities. In addition, the effect occurs more robustly with low and medium technology intensive firms than it does with high technology intensity ones.
Keywords: R&D; research and development; innovation; government incentives; fiscal incentives; reimbursable incentives; innovation policy; policy instruments.
Sustainability in Development: Rethinking About Old Paradigms
by Reza Hafezi, Mohsen Bahrami, AmirNaser Akhavan
Abstract: Sustainable development has become an important issue in long-term planning due to the limitation of natural resources and ethical responsibilities to future generations to meet their needs. Some of researches in this field investigated case studies in order to answer environmental concerns. Others went behind and presented a multi-dimensional view, considering economic and social aspects, in addition. This paper suggests a comprehensive rethinking about sustainable development discourse. A three-level meta-model is presented to map interconnections between fundamental aspects of social and personal life (ethics, beliefs and values) and sustainable development. These three levels are: (1) Fundamental level (consists of a world view perspective), (2) Interactive level (frameworks in which elements of fundamental level translated to behavioral conditions) and (3) peripheral level (defines processes to form interacts with the universe) .This rethinking procedure proposed a more basically investigations to guarantee the outcomes of a sustainable development process.

Study of lead and copper accumulation by selected botanical species in urban environment
by DJEDOUX MAXIME ANGAMAN, Y.A.O. SADAIOU SABAS BARIMA, ZAMBLE FIDELE TRA BI, BINI KOUAME DONGUI
Abstract: The aim of this study is to quantify lead and copper concentrations deposited on plant species exposed in different habitats of Abidjan in order to assess air quality of Abidjan. Five species were used Barleria prionitis, Cassia surattensis, Duranta repens, Ficus benjamina, Jatropha interrigima and exposed in Parks, Main Roads, Industrial and Residential zones.
Leaf samples were collected and the concentrations of copper and lead were carried out by Inductively coupled plasma mass spectrometry. Roads generally showed high levels of copper and lead and the highest values reached 13 mg.g-1 and 7.5 mg.g-1 respectively. While the lowest were found in Parks with the values 2 mg.g-1 for Cu and 0.5 mg.g-1 for Pb. These results suggest that the major source of pollution were car exhaust. However, C.surattensis at roadsides showed the highest deposition of Cu and Pb. A significant positive correlation between lead and copper concentration in three leaves species, Cassia surrattensis (r = 0.974; p = 0.0043), Duranta repens (r = 0.824; p = 0.0057) and Jatropha interrigima (r = 0927; p = 0.00001) were found.
Keywords: Lead and copper contents; air pollution; plant leaves; ICP-MS.
Crop Farmers Understanding of Climate Change and Adaptation Practices in South-east Nigeria
by Robert Onyeneke, Chinenye Mmagu, Jonathan Aligbe
Abstract: This paper investigated crop farmers perception and adaptation practices to climate change in South-east Nigeria based on climatic data from a meteorological station and information from a review of 30 published studies about practices that boost farmers resilience or reduce their vulnerability to observed or expected changes in climate. Data collected from meteorological station were subjected to trend analysis, while farmers perception on climate change and adaptation were subjected to detailed literature review. Results confirmed the evidence of climate change in the area and that the farmers noticed the change. The review revealed that crop farmers in South-east Nigeria are already using a wide range of creative practices to deal with climate risks; these can be further adjusted to the challenge of climate change by planned adaptation programs. We found 41 different practices relevant to climate change adaptation and organised them in five categories: farm management and technology; farm financial management; diversification; mobility and social networks; and knowledge management and regulations. We concluded that adaptation policies should complement farmers autonomous response to climate change through crop improvement and cropland management, provision of financial services, investments in local knowledge and social networks, and implementation of policies to enhance good local governance and livelihood diversification.
Keywords: Climate change; perception; adaptation; trend analysis; crop farmers; South-east Nigeria.
SIMULTANEOUS ELECTROCOAGULATION OF DAM WATER AND PRODUCTION OF HYDROGEN
by Arturo Bailon, Thelma Pavón-Silva, Jorge Ibanez, Gabriela Roa-Morales
Abstract: The aim of this project was to design, build, and test a novel electrolyzer for the simultaneous electrocoagulation of dam surface water and production of hydrogen. Costs were reduced by using stainless steel (SS) and aluminum (Al) electrodes. However, operating the electrolyzer with SS as the anodic material and Al as the cathodic material released up to 5.2 mg/L of chromium into the treated water. To prevent chromium release the SS anode was replaced with an Al anode, which yielded an average hydrogen production efficiency of 35.3% and an average hydrogen purity of 92.6%. In a novel scheme, the reactor simultaneously produced cathodic hydrogen and electrocoagulated surface water, which removed color, turbidity, hardness, chemical oxygen demand (COD), nitrates, nitrites, ammonia nitrogen, and total coliforms. There are several advantages to using this system instead of the traditionally used proton exchange membrane (PEM) electrolyzer: a) surface water can be used without pretreatment, b) a membrane is not required for gas separation, c) hydrogen production and surface water treatment can be conducted simultaneously, and d) the reactor can be coupled directly to a solar energy system.
Keywords: hydrogen production; electrocoagulation; paired processes; simultaneous processes; solar energy; surface water.
