Stilbenes are a group of chemicals characterized with the presence of 1,2-diphenylethylene. Previously, our group has demonstrated that synthesized (E)-N-(2-(3, 5-dimethoxystyryl) phenyl) furan-2-carboxamide (BK3C231) possesses potential chemopreventive activity specifically inducing NAD(P)H:quinone oxidoreductase 1 (NQO1) protein expression and activity. In this study, the cytoprotective effects of BK3C231 on cellular DNA and mitochondria were investigated in normal human colon fibroblast, CCD-18Co cells. The cells were pretreated with BK3C231 prior to exposure to the carcinogen 4-nitroquinoline 1-oxide (4NQO). BK3C231 was able to inhibit 4NQO-induced cytotoxicity. Cells treated with 4NQO alone caused high level of DNA and mitochondrial damages. However, pretreatment with BK3C231 protected against these damages by reducing DNA strand breaks and micronucleus formation as well as decreasing losses of mitochondrial membrane potential (ΔΨm) and cardiolipin. Interestingly, our study has demonstrated that nitrosative stress instead of oxidative stress was involved in 4NQO-induced DNA and mitochondrial damages. Inhibition of 4NQO-induced nitrosative stress by BK3C231 was observed through a decrease in nitric oxide (NO) level and an increase in glutathione (GSH) level. These new findings elucidate the cytoprotective potential of BK3C231 in human colon fibroblast CCD-18Co cell model which warrants further investigation into its chemopreventive role.

Contributions of Brazilian educational policies: possibilities for dialogue and valuing ethnic and racial diversity in the school context
Authors: Coelho Marciele Nazaré , De Lima Constantino Francisca
Published: March 2020

The diversity of cultures, of ways of being and existing in the world is increasingly seen as a process present in the context of schools and especially in classrooms. Immigration, internal and external displacements, different cultures, ethnicities present in the school imply reflections of an emancipatory, dialogical education that demands from teachers, male and female students, a positioning and a dialogue in favor of unity in diversity and in favor of equality of differences. In this perspective, we dedicate ourselves to dual and emancipatory theories that can contribute to the reflection of the events that took place in the educational context. Based on the communicative methodology, the analysis of educational practices, based on a section of the field research already completed, brings to the dialogue the possibilities that the school has in working with Brazilian legislation within the scope of black, Afro-Brazilian and African culture. From the results, we present the possibilities of an anti-racist education that favors dialogue and respect among the different.
Colonial Privileges in a Settler Society: Disparities of Cultural Capital in a University Setting
Authors: Mayeda David , Pukepuke Tepora , France Alan , Cowie Lucy , Chetty Marilyn
Published: March 2020

Drawing on forty one-on-one interviews with third year students from The University of Auckland, this study contrasts the experiences of students from working- and upper-class backgrounds. In particular, the study demonstrates how working-class students, most of whom come from Indigenous Māori and Pacific ethnic backgrounds, are forced to navigate obstacles infused with interpersonal and institutional racism. These students also report a stigmatising awareness of their lack of privilege and sense of obligation to give back to their ethnic communities. In contrast students from upper-class backgrounds, though hard-working, discuss a litany of opportunities extending their academic and occupational privilege. These capital-building opportunities are tightly connected to consistent family support in the form of gifted money, flexible work options, and networks that enhance professional experience. Working with kaupapa Māori and Bourdeausian conceptual frameworks, the study highlights privileged students’ ability to access and extend their objectified cultural capital, as less economically privileged students work their way through colonial blockades and classed pitfalls. Given the clear disparities expressed by study participants, the research suggests universities radically reframe how resources are allocated to students from diverse backgrounds.

"We are achieving this… Eliminating the violence and making us all Friends”. The power of friendships to generate peaceful coexistence in Sant Roc (Badalona)
Authors: Villarejo-Carballido Beatriz , Garcia Yeste Carme , Ramis Maria del Mar , Ruiz-Eugenio Laura
Published: March 2020

This article analyses the contribution of friendship between members of different cultures to improving peaceful coexistence in a vulnerable neighbourhood. Specifically, it analyses the personal friendship between Said, a member of the Pakistani community, and Tio Antonio, a member of the Roma community, as a turning point in improving the coexistence in a neighbourhood which had been experiencing conflictive situations and clashes between the residents for years, especially between the Roma and the Pakistani communities. This friendship has played a mediating role and served as an example for other friendships between members of the two communities, leading to the creation of a joined organization. This analysis contributes to the existing literature, where the role of personal friendship in the transformation of conflictive intercultural relations into peaceful, constructive ones has barely been explored.

Comparative Analysis of Agronomic Traits and ISSR Method among Some Soybeans [Glycine Max (L.) Merr.] Genotypes
Authors: ARSLAN Emine , GÜLBAHÇE MUTLU Elif , DURSUN Ömer , BAĞCI Seydi Ahmet
Published: March 2020

In this study, the genetic diversity was investigated among 12 soybeans genotypes using inter simple sequence repeats (ISSR) and agronomic traits. DNA was isolated from the leaves of the genotypes. For molecular characterization, a total of 26 primers of ISSRs and eight agronomic characteristics were evaluated. ISSR analysis revealed 88 polymorphic bands. The genetic diversity among the genotypes according to ISSR analysis and agronomic traits were estimated based on Nei homology and Euclidian distance, respectively, and dendrograms reflecting genetic similarity were constructed using UPGMA and NTSYSpc, respectively. Nei’s homology coefficient values used for ISSR analysis ranged from 78%-84%, and the average Euclidean distance used for agronomic data ranged from 1.96-9.77. Although soybean genotypes evaluated in this study were highly similar, dendrograms showed that these genotypes could be distinguished both morphologically and genetically.

Analyses of Bio-Energy Properties from Malaysian Local Plants: Sentang and Sesendok
Authors: Hossain Nazia , Jalil Rafidah
Published: March 2020

Various types of plants with several energy analysis methods have been experimented to produce bio-energy. In this study, two Malaysian local plants Sentang (Azadirachta excelsa) and Sesendok (Endospermum malaccense) have been used to determine their capability of bio-energy production. Our study focused on the analyses of bio-energy properties by using proximate analysis method separating moisture content (%), volatile matter (%), ash content (%), fixed carbon (%) and calorific value (MJ/kg) from Sentang and Sesendok. Proximate analyses of these plants proved lengthy flammability, very high amount of ignition, heat generation, net energy and negligible pollution effect. The calorific values for Sentang and Sesendok are 16.84 MJ/kg and 16.95 MJ/kg respectively. As Malaysia is tropical country mapping a large area of land with an evergreen plantation, so both trees Sentang and Sesendok species would be the efficient sources of bio-energy production.

Ecological Economics - Abridging the Gap between Conventional Economics and Ethics
Authors: Toufique Mohammad Mokammel Karim
Published: March 2020

What role do ethics play in differentiating Ecological Economics from conventional Economics? How much ethical underpinning do various blazing environmental issues have? These are the question that this paper tries to answer.   Conventional Economics focuses on the efficiency of resource allocation giving less weight to distribution and scale. But many economic problems have important ethical dimensions or implications. Mainstream economists have always ignored ethics as a key issue in economic theory.  On the contrary, ecological economics argues that, in the face a severe environmental problem it is normal and natural for human beings to have concerns about the crisis and a healthy survival and to adopt a position of precautionary rationality. Ethics has important policy implications for market-based solutions, valuation, various environmental issues, the business world and its environmental responsibility, globalization, financial crisis etc. Ethics should not be analyzed in isolation of other factors affecting the economic phenomenon concerned. Future research should focus on how to formally incorporate ethics in standard economics model of various forms.

Authors: Islam Md. Maidul , Rashi Md. Mamun Ur
Published: March 2020

The DC-DC converter find a wide scope in industries, telecommunication sectors, power electronics area, etc. Nowadays bi-directional converters have a higher end over them since the energy from the load during regenerative braking is fed back to the source, thus obtaining energy efficient system. A single topology that can provide Buck-Boost operation with positive output having four quadrant operations is not available in the literature.  A common limitation of power coupling effect in some known multiple-input dc-dcconverters has been addressed in many kinds of literatures. In this paper, a new single topology of two quadrants DC-DC Sepic converter has been developed to provide four quadrant operation of a high- frequency dc-dc converter having one supply source and proper control of the converter. The combined topology has been analyzed and studied by spice simulation.

Authors: Sarkar Md. Sujahangir Kabir , Sadeka Sumaiya , Sikdar Md. Mehedi Hasan , Badiuzzaman
Published: March 2020

Energy consumption is increasing due to the expansion of economic activity and population size which results higher GHG emission worldwide. The study has examined the trends of energy consumption and CO2 emission in Bangladesh using the secondary data extracted from the World Development Indicators of the World Bank database. The results found that there is an increasing trend of total energy consumption and per capita energy consumption in Bangladesh from 1991 to 2012 where the total energy consumption has been increased nearly three times from 12.55 mtoe (million tonne oil equivalent) in 1991 to 33.17 mtoe in 2012. The total CO2 emission was estimated by 57.07 mtoe in 2011 which was increased by 140.67% compared to the 1991 emission of 15.94 mtoe. Thus, the CO2 emission and per capita emission has also provided increasing trend over the period of 1991 to 2011.It has revealed that the growth of CO2 emission found to be higher than the growth of GDP and energy consumption in Bangladesh. The yearly average growth of CO2 emission has estimated by 6.7% which is higher that the annual average growth of GDP and energy consumption as of 5.25% and 4.77% respectively. This situation calls for serious attention of the country for reducing CO2 emission. Therefore, government needs to develop a national mitigation plan/policy and promote the use and development of green technology, renewable energy and green growth for sustainable energy and environment in Bangladesh.

Major Oxides Geochemistry of Tourmaline from Selected Gem-Mineral Deposits in Southwestern Nigeria
Authors: Olatunji A. S. , Jimoh Onawola Razak
Published: March 2020

Tourmaline occurs in associations with other gem minerals such as beryl, topaz, garnet and kunzite alongside rock-forming minerals like quartz, feldspar and muscovite in various gem mineral deposits across southwestern Nigeria. These occurrences of tourmaline in varieties of colors resulting from its range in chemical compositions remain puzzling, more so when there is a lack of sufficient information on the chemistry of the Nigerian tourmalines. This study is aimed at the major oxides investigation of tourmalines from selected gem-mineral deposits in southwestern Nigeria and how the chemistry can be used to infer their environment and processes of mineralization. A total of 22 differently colored tourmaline samples obtained from different locations in southwestern Nigeria were prepared and analyzed, using the inductively coupled plasma - mass spectrometry (ICP-MS) to determine the elemental constituents. Komu and Ijero-Ekiti, being the two areas with highest concentrations of the study samples were specially chosen and mapped, at least to reveal the geology of some gem mineral deposits in the area. Results of the geochemical analysis of the tourmaline samples showed enrichment in SiO2 and Al2O3, but depletion in the remaining major oxides. However, a few of the tourmaline samples showed unusual enrichment in CaO, revealing the fact that the samples have crystallized from highly fractionated melt. The major oxide compositions of the tourmalines exhibited wide and distinct variations, especially in SiO2, Al2O3 and CaO, indicating magmatic origin for the southwestern Nigerian tourmalines. Similarly, the strong negative correlations observed between CaO and the oxides Al2O3, Na2O, K2O and SiO2 in the tourmaline samples, coupled with the relatively high Fe/Fe+Mg ratio, averaging 0.89,clearly reinforced magmatic sourcing for the tourmalines. Almost all the southwestern tourmaline samples plot in the predefined field of Li-rich granitoidpegmatites and aplites in the Al-Fe-Mg and Ca-Fe-Mg plots. Southwestern Nigerian tourmalines are thus magmatic in origin with their chemistry reflecting control by host rocks and granitic-pegmatitic fluid. The study also revealed that the intensity of coloration in tourmalines can be linked to the presence or otherwise of iron concentration. The iron content varies directly and proportionately with the depth of color in the greens, and inversely in the pinks and reds.
Marine Spatial Planning: Bangladesh Perspective
Authors: Alam Md. Asraful
Published: March 2020

The concept of Blue Economy has triggered the coastal states to explore their marine resources from their own maritime boundaries. Bangladesh has to be one step advance in the competition as its land based resources are very limited in comparison to its huge population. It must be very critical for Bangladesh if it does not have a well-planned policy adopted in considering both the economic and environmental aspects. MSP can only be the process for Bangladesh to go ahead for consumption of marine resources without jeopardy to marine environment. The existing national policies, plans and legislations for ocean governance are very scattered in nature which needs to be an integrated and uniform legal stand. The study analysis those legal loopholes and recommends for an effective MSP in the Bay of Bengal.

The experiment was conducted in the field laboratory of Spices Research Center, BARI, Shibganj, Bogra, Bangladesh during Rabi season of 2014-15 to find out the effect of biopesticides in controlling vector as well as leaf curl virus of chilli. The maximum infected plants (26.85%) were recorded in untreated control and the minimum infected plants (14.75%) were in Malathion (0.2%) which was statistically identical to all other biopesticides except cow urine (1:2). The highest disease reduction (45.13%) over untreated control was obtained from Malathion (0.2%) followed by cow urine (1:1) and neem leaf extract (1:2), and the lowest (26.37%) was obtained from cow milk (1:2). The highest yield (18.33 t/ha) was recorded in Malathion (0.2%) and the lowest (11.28 t/ha) was recorded in untreated control. All the biopesticides resulted least disease incidence and more yield compared to control. Among the biopesticides, cow urine (1:1), cow milk (1:1) and neem extract (1:2) showed comparatively better results against control. So, Melathion or biopesticides, cow urine (1:1), cow milk (1:1) and neem leaf extract (1:2) may be sprayed for controlling vector as well as leaf curl virus and increasing yield of chilli.

The study was carried out to evaluate the farmers’ knowledge, attitudes and perception of the pesticides handling, application, and residue on the cassava roots produced and associated health and environmental risk exposures factors among the farmers in Apoje Farm Settlement Ogun State Southwestern Nigeria. A total of twenty-five (25) cassava root samples produced on the farm were collected and analyzed for the presence of any residues while fifty (50) farmers were randomly sampled with the administration of structured questionnaires/interviews. The results obtained showed the detections of polychlorinated biphenyl (PCB), Nitrate (NO3) and Hydrogen sulphide (H2S) with mean values of 0.01934mg/kg, 0.012564mg/kg and 0.00058mg/kg respectively that fall within the regulated limits. However, the knowledge of the farmers on pesticides handling and application are low, some cannot read the labels on the pesticides to understand the poison and hazards signs. Then, they exhibit poor attitudes and perceptions of health and environmental risks associated with the exposure to the pesticides. The majority of the farmers do not put on personal protective gadgets to prevent themselves from the exposures. The study concluded that there should be health talks organized for the farmers on the subject matter and there is an urgent need for resuscitations of farm extensions services where relevant government agencies support the local and semi-illiterates farmers given them adequate and necessary information on the handling and application of pesticides in order to reduce the risks to the farmers, the inhabitants, and the environment. Then, monitoring studies of human exposure, the soil and water bodies in the study area are required to evaluate the effects the pesticides.

Published: March 2020

Heat pipe was reviewed in former time which was in linear design. But in most cases, the heat pipe is needed in a bent shape. For instance, in a car, the heat transfer way from the engine to the radiator is not in linear. To move heat from parts in a computer i.e. central processing units of the computer may use non-linear heat pipe to reduce the heat generated in it. So the performance analysis for a bent heat pipe is badly needed to fulfill the current demand. In this research, a bent heat pipe was constructed and the performance analysis have been conducted on the bent heat pipe.
Iran’s Oil and Gas Legal Framework: from Exploration to Revolution
Authors: Kardel Mahmoud Fard
Published: March 2020

The main purpose of this article is to examine Iran’s legal and contractual framework for their petroleum, oil and gas industry. Basically, the legal and contractual framework of the Iranian oil and gas industry has been classified into three periods. The first period is from the exploration and discovery of oil in Iran to nationalisation (1901-1951), the second period is from nationalisation to revolution (1951-1979), and the third period is from revolution to the present day (1979-20016).Because each period has its own features and importance two articles will examine this topic. The first period (from exploration to nationalisation, 1901-1951), and second period (from nationalisation to revolution, 1951-1979), has been examined in this article with legal and comparative analysis, and the third period (1979-2016) will be covered in a later article.It should be mentioned that each contractual framework was a turning point regarding to opportunities and circumstances that they have been in that time and also each of those petroleum contractual regimes were a step toward to contractual framework evolution in Iran.
Integrated Water Resources Management (IWRM): Maximise Usage and Minimise Wastage of Water Resources
Authors: Alam Sheikh Mahabub
Published: March 2020

Following the implementation of GWP (Global Water Partnership) in 1996 by UN the countries around the world began to implement the principles of IWRM to minimize water waste and maximize its beneficial use. The Ministry of Local Government, Rural Development and Cooperative in Bangladesh also adapted the idea and created IWRM unit in 2003 through WARPO, CEGIC and IWM. Bangladesh is going through serious shortages of fresh water resources. Major reasons are: diversion of natural river flow in the upstream area; rapid siltation on river beds which have seriously reduced water holding capacity causing regular floods destroying crops, making people homeless and even loosing many lives, destroying economic progress; and change of climate pattern, seawater encroachment due to sea level rise destroying fresh water resources and cropping lands due to climate change impact and greenhouse gas emission. To overcome these issues the country must adapt the following steps: implementation of IWRM practices to its maximum capacity. IWRM will include surface water, groundwater, waste water and sewage water resources to design its maximum utilization. In addition WSUD techniques; urgent dredging of rivers; positive negotiation with the neighbors for surface water sharing and storing excess surface water during monsoon at series of reservoirs built in upstream locations and use them during dry season. The biggest task of Bangladesh IWRM is to educate all stake holders; establish proper coordination among all water management sectors and train up end users to transform them as guardian angels of water conservation.
Effects of Quantum Confinements in Tin Sulphide Nanocrystals Produced by Wet-Solution Technique
Authors: Mosiori Cliff Orori
Published: March 2020

In thin film nano-crystals studies, electron energy levels are known not continuous in the bulk thin films but are rather discrete(finite density of states) because of confinement of their electron wave functions to the physically dimensions of the particles. This phenomenon is called Quantum confinement and therefore nano-crystals are also referred to Quantum dots. The quantum confinement effect is mainly observed when the size of the particle involved is too small to be comparable to the wavelength of the electron. To understand this effect, this study broke the words confinement to mean to confine the motion of randomly moving electron to restrict its motion in specific energy levels (discreteness) and the term quantum to reflect the atomic realm of particles involved in this study. So as the size of a particle decrease to a nano scale, then the decrease in confining dimension causes the particle energy levels to be too discrete and at the same time widens up the band gap. As a result the ultimately effect is that the band gap energy increases. In this study, nanocrystalline tin sulphide (SnS) powder was prepared using tin chloride (SnCl2) as a tin ion (Sn+2) source and sodium sulfide (Na2S) as a sulfur (S-2) ion source using solution magneto DC sputtering technique. The as-synthesized thin film in form of nanoparticles were then qualitatively and quantitatively analyzed and characterized in terms of their morphological, structural and optical properties and found to have an orthorhombic structure whose direct band gap had blue shifted (1.74 eV) and was confirmed using theoretical calculations of exciton energy based on the potential morphing method (PMM) in the Hartree Fock approximation.

Published: March 2020

At present, the condition of surface water is much declining and the quality of water is a vital concern for mankind. It is directly linked with human security. Greater part of people is still not aware of it. So, improvement of the condition of surface water is a crying need. Surface water is often physically contaminated due to unhygienic practices. Discharges from various contaminated sources are very common thing in city life which deteriorates the water quality and necessary treatment is required to make water usable. The investigation is based on laboratory tests on water samples obtained from seven Ponds and three Charas of Sylhet City Corporation. The selected parameters for assessing the water quality are PH, Biochemical Oxygen Demand (BOD) and Dissolved Oxygen (DO). The present condition of Ponds and Charas water are not up to the mark and it is declining day by day. Proper initiatives need to take regarding the control of surface water pollution in Sylhet.
