Application of Resource Efficient and Cleaner Production (RECP) in the Energy Intensive Industry to Promote Low Carbon Industrial Development in Bangladesh  [PDF]
Tahazzud Hossain
Low Carbon Economy (LCE) , 2015, DOI: 10.4236/lce.2015.63009
Abstract: The consumption of natural resources (e.g. raw material, water & energy) in the industries is bringing welfare to the society but per unit of product from the industry is linked with the generation of environmental pollutants and emissions. Resource constraints and climate crisis have come into focus globally; particularly it has become one of the major concerns in the Asia Pacific region. At present, the countries in the Asia Pacific use resources three times greater than the rest of the world to generate one unit of GDP. These countries are more vulnerable to the impacts of resource constraints and climate change. Resource Efficient and Cleaner Production (RECP) has come as a preventive environmental measure to facilitate pollution prevention and reduce carbon intensity per unit of products along with financial profit of the industry. Bangladesh has been considered as one of the transition economies in the South Asia. Industrial sector supports second largest share to the GDP of Bangladesh. The industrial productivity in the country is solely dependent on the locally available natural gas and imported raw materials. Energy Efficiency (EE) and Cleaner Production (CP) measures in the industry can facilitate the promotion of low carbon industrial development through pollution prevention and energy conservation. The main objective of this research is to identify the policy instruments for the promotion of low carbon industrial development in Bangladesh within RECP framework. In this research, ceramics sector has been taken as a research unit. Based on the research objective, three research strategies have been followed which are: 1) review of the existing Environmental Policy, Industrial Policy and Energy Policy of Bangladesh, 2) review of the relevant measures adopted in the regional countries, and 3) case study in a ceramic industry. Stakeholder consultation has been conducted to identify appropriate policy instruments based on multi-criteria evaluation. Through this research, eleven policy instruments have been identified in connection with the promotion of RECP measures in the country with the target of developing low carbon industrial operation. Among the eleven policy instruments seven policy instruments have been identified as prioritized policy instruments based on multi-criteria evaluation through stakeholder consultation. Apart from the prioritized policy instruments the Government of Bangladesh (GoB) has to make realistic sector wise policies and specific policy targets to be achieved within timeline. The GoB has to increase
An Econometric Analysis for CO2 Emissions, Energy Consumption, Economic Growth, Foreign Trade and Urbanization of Japan  [PDF]

Low Carbon Economy (LCE) , 2012, DOI: 10.4236/lce.2012.323013
Abstract: This paper examines the dynamic causal relationship between carbon dioxide emissions, energy consumption, economic growth, foreign trade and urbanization using time series data for the period of 1960-2009. Short-run unidirectional causalities are found from energy consumption and trade openness to carbon dioxide emissions, from trade openness to energy consumption, from carbon dioxide emissions to economic growth, and from economic growth to trade openness. The test results also support the evidence of existence of long-run relationship among the variables in the form of Equation (1) which also conform the results of bounds and Johansen conintegration tests. It is found that over time higher energy consumption in Japan gives rise to more carbon dioxide emissions as a result the environment will be polluted more. But in respect of economic growth, trade openness and urbanization the environmental quality is found to be normal good in the long-run.
Recurrent Support and Relevance Vector Machines Based Model with Application to Forecasting Volatility of Financial Returns  [PDF]
Altaf Hossain, Mohammed Nasser
Journal of Intelligent Learning Systems and Applications (JILSA) , 2011, DOI: 10.4236/jilsa.2011.34026
Abstract: In the recent years, the use of GARCH type (especially, ARMA-GARCH) models and computational-intelligence-based techniques—Support Vector Machine (SVM) and Relevance Vector Machine (RVM) have been successfully used for financial forecasting. This paper deals with the application of ARMA-GARCH, recurrent SVM (RSVM) and recurrent RVM (RRVM) in volatility forecasting. Based on RSVM and RRVM, two GARCH methods are used and are compared with parametric GARCHs (Pure and ARMA-GARCH) in terms of their ability to forecast multi-periodically. These models are evaluated on four performance metrics: MSE, MAE, DS, and linear regression R squared. The real data in this study uses two Asian stock market composite indices of BSE SENSEX and NIKKEI225. This paper also examines the effects of outliers on modeling and forecasting volatility. Our experiment shows that both the RSVM and RRVM perform almost equally, but better than the GARCH type models in forecasting. The ARMA-GARCH model is superior to the pure GARCH and only the RRVM with RSVM hold the robustness properties in forecasting.

American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.36085
Abstract: In vitro organogenesis of an upland species of Colocasia esculenta cv. antiquorum L. was examined in relation to different explants like meristem and parenchymatous storage tissues with or without anthocyanin layer, four levels of each of Kn, 2,4-D, NAA and BAP and four incubation environments such as: 1) 16 h 3 Kl light intensity + 24°C ± 2°C; 2) 24 h dark + 24°C ± 2°C; 3) 24 h dark + 30°C ± 3°C and 4) 12 h diffuse light + 30°C ± 3°C. Only meristems showed proliferation with various degree of intensity both at 16 h 3 Kl light + 24°C ± 2°C and 24 h dark + 24°C ± 2°C conditions and poor response with different levels of Kn + NAA either in light or in the dark. Cultures with NAA + BAP were proliferated very quickly with very high degree of intensity. The cultures under dark did not proliferate for 20 days which upon transfer to light showed high degree of proliferation. Cultures with NAA + BAP formed calluses more pronouncedly at dark than that occurred in the light. Parenchymatous tissues with or without anthocyanin did not proliferate but the tissues with anthocyanin lost pigmentation after 25 - 30 days and turned to grey colour after 50 days while tissues without anthocyanin turned to green colour with shinny pimples indicating that protocorm may be developed. No culture under high temperature environment (30°C ± 3°C) neither survived nor proliferated. The meristems in culture were died within 15 - 20 days while others within 25-30 days. In conclusion, a combination of NAA (0.5 - 3.0 mg/l) and BAP (0.5 - 2.0 mg/l) and an incubation photoperiod of 16 h coupled with temperature of 24°C ± 2°C were found most suitable for in vitro culture of Colocasia esculenta cv. antiquorum L.

Shahadat Uddin, Liaquat Hossain
Social Networking (SN) , 2013, DOI: 10.4236/sn.2013.21004
Abstract: Dyad and triad census summarize much of the network level structural information of a given directed network. They have been found very useful in analyzing structural properties of social networks. This study aims to explore crisis communication network by following dyad and triad census analysis approach to investigate the association of microlevel communication patterns with organizational crisis. This study further tests hypothesis related to the process of data generation and tendency of the structural pattern of transitivity using dyad and triad census output. The changing communication network at Enron Corporation during the period of its crisis is analyzed in this study. Significant differences in the presence of different isomorphism classes or microlevel patterns of both dyad and triad census are noticed in crisis and non-crisis period network of Enron email corpus. It is also noticed that crisis communication network shows more transitivity compared to the non-crisis communication network.
Influence of Recycled Aggregate Composites on the Factor of Safety of Earthen Structures  [PDF]
Md. Zakaria Hossain
International Journal of Geosciences (IJG) , 2013, DOI: 10.4236/ijg.2013.45078

In this study, six composite reinforcements such as cement composite made of Abandoned Cell Husks (ASH), Stones, Wood chips, Concrete and Bricks have been used along with control specimen. It is known that the material used in earth reinforcement applications must be safe against tension failure and adhesion failure for its effective utilization in the field and reliable design of earth structures. Single type of material can provide limited reinforcement capability in reinforced earth structures due to its low frictional resistance and poor cohesion. For an optimal response, therefore, composite reinforcement, that fulfils both the requirements such as possess adequate tensile strength and adequate frictional resistance, is getting considerable attention. Slope stability analyses containing six types of reinforcement have been performed. Stability of the slope has been quantified using minimum factor of safety corresponding to critical slip surface. It was observed that the composite reinforcement whose surface treated by brick aggregate enhanced the factor of safety significantly. The paper also depicted the design aids of reinforced slope in terms of embedding lengths and spacing of reinforcements.

Waste Shell Husks Concrete: Durability, Permeability and Mechanical Properties  [PDF]
Md. Zakaria Hossain
Journal of Building Construction and Planning Research (JBCPR) , 2013, DOI: 10.4236/jbcpr.2013.13009
Abstract: Shell husk is annually produced as a byproduct of shell production in Japan. According to Japanese Ministry of Forestry, Fisheries and Agriculture, the amount of the abandoned shell husk is about 151,000 tons per year. This huge amount of abandoned shell husk is not only thrown away without any commercial return but also causing pollution and environmental problems. To mitigate the pollution and environmental problems, possible utilization of abandoned shell husk is thoroughly observed in concrete construction. Overall response of the mechanical properties of concrete specimens containing different percentage of abandoned shell husk aggregates such as 0, 10%, 0, 30%, 40% and 50% in the ratio of mass is demonstrated. Results of engineering properties such as compressive strength,Young’s modulus, tensile strength, unit weight, water absorption capacity and coefficient of hydraulic conductivity are depicted. It is observed that the use of shell husk in concrete improves strength and durability performance of concrete treated in aggressive sea environments.

A Critical Analysis of Empiricism  [PDF]
F. M. Anayet Hossain
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.43030
Abstract: Empiricism is a philosophical theory which argues that human knowledge is derived entirely from sensory experience. As a branch of epistemology, empiricism disregards the concept of instinctive ideas and focuses entirely on experience and evidence as it relates to sensory perception. Empiricism is a philosophical school holding that knowledge can only be (or is primarily) gained from sensory experience. Accordingly, it rejects any (or much) use of a priori reasoning in the gathering and analysis of knowledge. It rivals rationalism according to which reason is the ultimate source of knowledge. The philosophy of empiricism was first put forth in John Locke’s An Essay Concerning Human Understanding. Locke argued that the only way by which human acquire knowledge is through experience. Locke firmly argued that humans are incapable of formulating or possessing inherent ideas. The aim of this paper is to explain that the traditional empiricist standpoint in the fields of epistemology and then try to show that it is not adequate for explaining some things relevant to these fields. For that the traditional empiricist methods needs to be supplemented by extra-logical principles that are not strictly empirical.

This as a result that has created a debate between different marketers to choose a beneficial way to satisfy by attracting different customers. This article focuses on various problems which marketers face in terms of online retailing as well as different obstacles encountered by consumers while making buying decisions for standardized or customized products through online Medium (Internet).
Understanding the Society and Governance of Bangladesh through the Lens of Ibn Khaldun  [PDF]
Samiul Islam, Amzad Hossain
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.54018
Abstract: This article attempts to ground the relevance and importance of 14th century’s multifaceted social scientist Ibn Khaldun in the context of the overall social, cultural, economic and political journey of Bangladesh. The famous book of this eminent Muslim thinker the Mukaddimah is considered as the conceptual basis of this study. More precisely, from a sociological point of view, the article tries to examine Khaldun’s concept of ‘Asabyyah (solidarity), Umran (the nation) and Madaniyyah (civilization) in the context of Bangladesh. Doing so, a historical analysis of the society and culture of this delta will be portrayed first from Khaldun’s framework of social interpretation. Then, the second part will focus on the continuous formation and reformation of Bangladesh as a state and as a unique society through its contemporary experiences at various social-cultural, economic and political contexts on the basis of both from local and global perspectives. The study gathers the nectar from the Muqadimmah, translation of the original text by Ibn Khaldun along with various journal or research papers by different scholars around the world. The study found that Khaldun’s idea of ‘Asabyyah is extensively applicable in explaining the historical, social and political process of Bangladesh. After discovering historical context, the study found that Khaldun can be considered one of the prime philosophers to address the future of the people of Bangladesh as a sustainable society and a proud nation through creating self-ego that will boost up its citizens in cooperating morally and intellectually from local to global.
