Fahmida Akter, Md Altab Hossin, Golam Moktader Daiyan, Md. Motaher Hossain
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.64007
Abstract: Over the years, the amount of information about patients and medical information has grown substantially. Moreover, due to an increase of blood diseases patients, conventional diagnostic tests have been using by the medical pathologists which are low in cost and result in an inaccurate diagnosis. To recognize optimal disease pattern from hematological data, a reliable prediction methodology is needed for medical professionals. Data mining approaches permit users to examine data from various dimensions, group it and sum up the relationships identified. Classification is a vital data mining technique with extensive applications. Classification algorithms are applied to categorize every item in a set of data into one of a known set of classes. The objective of this paper is to compare different classification algorithms using Waikato Environment for Knowledge Analysis and to find out a most effective algorithm for end-user functioning on hematological data. The most efficient algorithm found is Random Forest having accurateness at 96.47% and the overall time is taken to construct the model is 0.16 seconds which is more efficient than different existing works. On the contrary, Multilayer Perceptron classifier has the lowest accuracy of 75.29% with 1.92 seconds to construct the model.

Ahsan Habib, Fahmida Hossain, Tahsina Ferdous, Khalilullah Muhammad Bayezid
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104604
Abstract:
This paper entitled “Social Networks and Social Ties: Changing Trends among Urban Dwellers in Bangladesh” discussed the impact of using social network sites on social ties. The main aim of the article is to reveal how internet and social networking sites reshapes our social relations especially in urban settings. The study followed qualitative way of analyzing social relations and its dynamics. Using empirical data, the article reveals how technological development is changing the contemporary world very rapidly. Changes are taking place in all spheres of life and ultimately these situations change our own society, conventional social thinking patterns and cultural beliefs. The internet is offering new forms of social relations and ties in both private and public sphere through social networking sites like—Facebook, Skype, Twitter, Viber, WeChat, WhatsApp and Imo etc.—that affect the pattern of our day-to-day interaction and relationships within families, communities and society at large. For these changes, human behavior is also changing and therefore, the study is becoming more important in the preset interpersonal relationship. Our contemporary way of living is demanding too much time away from natural social relationships because of technological advancement which is playing a major role for these changes and has a definite consequence on the social and cultural area of Bangladesh.

M. Ashraful Alam,Kudrat-e-zahan,M. Shamim Hossain,Fahmida Zerin Seema
Pakistan Journal of Biological Sciences , 2004,
Abstract: Three new cobalt -peroxo complexes [Co(2-apy)(O2)(OX), C1], [Co(2-apy)(O2)(2-ap), C2] and [Co(2-apy)(O2)(2-ab), C3] and two new zirconium μ-peroxo complexes [Zr(2-na)(O2)(OX), C5] and [Zr(2-ap)(O2)(OX), C5] were tested for their antibacterial activity by disc diffusion and serial dilution methods. All the coordination complexes were active against various test pathogenic organisms. The minimum inhibitory concentration (MIC) of the complexes was estimated between 32-64 μg ml-1 against Bacillus subtilis and Escharicha coli. The cytotoxicity of the five newly synthesized complexes was screened using brine shrimp lethality bioassay method and the LC50 values were calculated using probit analysis. LC50 values of the complexes C1-C5 were found 14.15, 9.12, 14.15, 29.51 and 5.75 7mu;g ml-1, respectively.
Reclamation of Lithium Cobalt Oxide from Waste Lithium Ion Batteries to Be Used as Recycled Active Cathode Materials  [PDF]
Rakibul Qadir, Fahmida Gulshan
Materials Sciences and Applications (MSA) , 2018, DOI: 10.4236/msa.2018.91010
Abstract: Waste laptop batteries (Type-Lithium ion) have been collected and manually dismantled in the current work. Active electrode materials were scraped off from the copper current collector and polyethylene separators. The aluminum current collectors were found to be severely damaged and attached with the electrode material. It was treated with NaOH later to be recovered as Al2O3. The leaching of LiCoO2 was done by 3 M HCl aided by 5% H2O2 at 60°C from the scraped active electrode materials (LiCoO2 and graphite) leaving the graphite completely. Co was precipitated as hydroxide by the addition of NaOH and later converted to Co3O4. The remaining solution was treated with saturated Na2CO3 to acquire Li2CO3 as crystalline precipitate with high purity. The recovery of Co and Li was 99% and 30%, respectively. Co3O4 and Li2CO3were mixed in stoichiometric proportions and calcined around 950°C with air supply to achieve LiCoO2 successfully.
Screening of Acetic Acid Producing Microorganisms from Decomposed Fruits for Vinegar Production  [PDF]
Farzana Diba, Fahmida Alam, Ali Azam Talukder
Advances in Microbiology (AiM) , 2015, DOI: 10.4236/aim.2015.55028
Abstract: Acetic acid bacteria capable of growing at 30°C - 37°C were collected from various decomposed fruits available in Bangladeshi local markets in order to assess their suitability for vinegar production. Initially, 42 microorganisms were isolated from decomposed fruits like grapes, mangoes, pineapples, oranges, safeda etc. during summer when temperature reaches up to 37°C. Then their growths were checked in YPG medium containing various ethanol concentrations at different time point at 37°C. From the preliminary screening, 15 Gram negative bacterial isolates have produced halos or yellow zone around the colonies on YPG agar plate at 37°C which indicated acetic acid production capability by those bacteria. Furthermore, acetic acid production rates were determined by titration method and about 3 - 6.9 gm/100ml acetic acid were estimated by using 4% ethanol at 37°C by shaking culture for 3 days. Several biochemical analysis revealed that our collection contained huge amount of acetic acid producing bacteria and some of them could be potential candidates for vinegar production.

Carcinoma cervix is the commonest gynaecological malignancy in developing countries while in developed countries, ovarian cancer is the commonest. Comprehensive statistics on gynecologic malignancies reported from Bangladesh are deficient. This study was performed to ascertain the profile of gynecologic cancers reported at our center regarding demography, the frequency
Music and Artistic Artefacts: Symbols of Rohingya Identity and Everyday Resistance in Borderlands
Kazi Fahmida Farzana
ASEAS : ?sterreichische Zeitschrift für Südostasienwissenschaften , 2011,
Abstract: This study looks at the creation of music and art by Rohingya refugees in Bangladesh as a symbol of social resistance and identity. Ethnographic research on the Rohingyas’ use of music and art suggests that these non-conventional means play an important role in communicating their coherent identity and expressing their resistance to the discrimination and oppression experienced in their country of origin as well as in their exile in Bangladesh. This informal resistance is used to keep their memory alive, to transmit that history through verbal and visual expressions to the new generations, and to communicate information about themselves to outsiders. This article posits that these forms of expression, while suggestive of their identity and everyday resistance, occur mostly in an informal and indirect form, rather than in direct confrontation and protest. These informal means also re ect the Rohingyas’ pragmatism and coping strategies for living in the borderlands. ----- Die vorliegende Studie untersucht die Bedeutung der Musik und Kunst der Rohingya-Flüchtlinge in Bangladesch als Symbole sozialen Widerstands und Ausdruck ihrer Identit t. Ethnographische Forschungen zur Rohingya-Musik und -Kunst lassen darauf schlie en, dass diese nicht-konventionellen Mittel eine wichtige Rolle bei der Vermittlung ihrer koh renten Identit t spielen und ihren Widerstand gegen Diskriminierung und Unterdrückung in ihrem Herkunftsland als auch im Exil in Bangladesch ausdrücken. Der informelle Widerstand wird dazu verwendet ihre Erinnerung lebendig zu halten, ihre Geschichte mittels verbaler und visueller Ausdrucksformen weiterzugeben sowie mit der jungen Generation und Au enstehenden Informationen über sich selbst zu teilen. Der Artikel postuliert, dass diese Ausdrucksformen – wenngleich suggestiv in ihrer Identit t und im allt glichen Widerstand – meist in informeller und indirekter Form auftreten und nicht mittels direkter Konfrontation und Protest. Die informellen Mittel spiegeln auch den Pragmatismus der Rohingyas und deren Bew ltigungsstrategien für das Leben in der Grenzregion wider.
Interclausal Logic Variables
Paul Tarau,Fahmida Hamid
Computer Science , 2014,
Abstract: Unification of logic variables instantly connects present and future observations of their value, independently of their location in the data areas of the runtime system. The paper extends this property to "interclausal logic variables", an easy to implement Prolog extension that supports instant global information exchanges without dynamic database updates. We illustrate their usefulness with two of algorithms, {\em graph coloring} and {\em minimum spanning tree}. Implementations of interclausal variables as source-level transformations and as abstract machine adaptations are given. To address the need for globally visible chained transitions of logic variables we describe a DCG-based program transformation that extends the functionality of interclausal variables.
An Econometric Analysis for CO2 Emissions, Energy Consumption, Economic Growth, Foreign Trade and Urbanization of Japan  [PDF]
Sharif Hossain
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.
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
