Published: November 2015

An experiment was conducted in randomized complete block design (RCBD) with three replications in the experimental field of Regional Horticulture Research Station (RHRS), Bangladesh Agriculture Research Institute (BARI), Lebukhali, Patuakhali during April, 2014 to October, 2014 for assessing the inbreeding depression, genetic parameters, gene action and segregation pattern of Okra [Abelmoschusesculentus (L.) Moench]. The experiment was comprised of five commercial hybrid Okra genotypes such as Tara sonali, Bimala, Juboraj, Suvo 1and Noor, their respective F2 progenies along with a check variety named as BARI Dherosh 1. Results of the experiment indicated that there were considerable variability among the F1 and their F2. The yield were in-between 14.81 to 7.92 Kg plot-1in case of F1 generation, which deteriorate to 10.32 to 5.32 Kg plot-1 in F2 generation. Broad sense heritability computed through variance component method showed that all the quantitative traits were moderate to highly heritable. The trait yield per plot exhibited 68.83% broad sense heritability coupled with 50.96% genetic advance suggesting the existence of sufficient amount of genetic variability for improvement of this trait and also indicates that the trait is more amenable to selection and could be improved easily. In case of segregation pattern, plant height and pod pubescence content exhibit as polygenic trait. Leaf shape, fruit base shape and branching pattern showed complete dominance and fruit color displayed incomplete dominance. The present investigation thus provide information about the nature and magnitude of genetic variation, segregation pattern and inbreeding depression for yield and its components in okra so as to formulate suitable breeding strategy and isolate potential parents and promising crosses for further breeding program.Asian J.

Published: November 2015

In order to investigate present status of aqua chemicals and drugs used in various aquaculture activities in Zakigonj upazilla, Sylhet. A survey was conducted, with carp polyculture, tilapia and catfish farmers, aqua-medicine sellers, representatives of pharmaceuticals companies, from July 2014 to November 2014. Each group consisted of 25 respondents. According to the survey the most common dose of lime used by the farmers during pond preparation (62.67%) and culture period (53%) is 0.5-1 kg/40m2. Urea and TSP used by the farmers mostly during culture period with most common dose of 100-150g/40m2(37.3%) and 50-100 g/40m2 (68%) respectively. Various categories of aqua drugs and chemicals were identified that were used by fish farmers for different purposes such as water quality management, disinfectants, improve dissolve oxygen level, disease treatment, antibiotics and growth promoter. Many pharmaceutical companies were found to provide these aqua drugs and chemicals with different trade names to fulfill the farmers demand. For pond and water quality management lime, urea and TSP are mostly used. Bleaching powder, Timsen, EDTA, Polgard, Virex, Aquakleen, Germnill, Pond safe were widely used as disinfectant. Health management and disease treatment were the major activities where farmers were seen to use a lot of chemicals. A range of chemicals including antibiotics were found available in market and being used in the aquaculture sector. Commonly found traditional chemicals in heath management included Potassium permanganate, Lime, Salt, Virex, Timsen, Aquakleen, Germnil, Pond Safe, Deletrix, Spa, Albez, Ablez were used regularly for disease treatment. Mostly used antibiotics are Renamycin, Oxysentin 20% Chlorsteclin Oxy-D Vet, Aquamycin, Orgamycin 15 %, Orgacycline-15% etc. Major active ingredients of these antibiotics were oxytetracycline, chlorotetracycline, amoxicillin, doxycycline etc. There are approximately fifty two pharmaceutical companies have been recorded to market around 300 products. Most of the products have been marketed from different countries like USA, Thailand, Malaysia, Belgium and China etc. The study also indicated some problems associated with the use of such chemicals due to lack of knowledge of farmers about the use of chemicals, appropriate dose, method of application and their indiscriminate use of chemicals. The study also highlighted the names and approximate price of aquaculture chemicals available with the chemicals sellers in Zakigonj, Sylhet.Asian J. Med. Biol. Res. June 2015, 1(2): 336-349

Authors: Wang Qiubao , Tian Ruilan
Published: November 2015

The paper addresses the bifurcations for a delay differential model with parameters which confers a strong Allee effect in Escherichia coli. Stability and local Hopf bifurcations are analyzed when the delay τ or σ as parameter. It is also found that there is a non-resonant double Hopf bifurcation occur due to the vanishing of the real parts of two pairs of characteristic roots. We transform the original system into a finite dimensional system by the center manifold theory and simplify the system further by the normal form method. Then, we obtain a complete bifurcation diagram of the system. Finally, we provide numerical results to illustrate our conclusions. There are many interesting phenomena, such as attractive quasi-periodic solution and three-dimensional invariant torus.

Authors: Malliarakis Kate Driscoll
Published: November 2015

Heroin use may be under-recognized among older adults. Baby Boomers are the largest age as well as the largest drug-using cohort in modern history. Although some drug users age out of their addiction, others do not. Nurses caring for older adults may come into contact with heroin users due to associated conditions or sequelae of their drug use that cause them to seek care. Few nurses are prepared to provide the care needed when heroin use accompanies other health problems. Using an individual example, the current article provides guidance for identifying heroin addiction, essential information about heroin use, and resources for guiding patients to experts for the comprehensive care needed for recovery.

Published: November 2015

El presente trabajo explora las motivaciones por las que las empresas españolas interaccionan con el Consejo Superior de Investigaciones Científicas (CSIC), describe los mecanismos que relacionan a ambos agentes, y, por último, explica el tipo de beneficio que han obtenido como producto de esta relación. Para ello, se analiza la información facilitada por 787 empresas españolas que han trabajado con el CSIC en actividades de innovación durante el periodo 1999-2010. El estudio permite concluir que las empresas, para relacionarse con el CSIC, prefieren y valoran mejor las motivaciones estratégicas que las tácticas, y en la relación utilizan una amplia variedad de mecanismos entre los que destacan los de apoyo tecnológico o consultoría y los de investigación contratada, mecanismos con bajo nivel de sofisticación. Además, los beneficios que las empresas obtienen rebasan los efectos sobre la innovación y, en consecuencia, sobre los beneficios económicos asociados a la misma, y cubren una amplia gama de resultados tangibles e intangibles.

Published: November 2015

Composite materials are created as a quite complex architecture which includes a fibre reinforcement structure and matrix material. Many material parameters play a role when composite structures are modelled, e.g. in finite element models. In addition to the properties of the raw fibre and matrix materials which are used, also geometrical parameters have a significant effect on structural characteristics. Fibre reinforcement geometry together with material properties of fibre and matrix determine homogenised material properties.The first part of the paper gives an overview of the most important processes which are used in composites processing industry. The factors which affect variability are also listed, and the effect of variability on material parameters is mentioned as well. The second part of the paper elaborates the identification of geometrical variability of the fibre reinforcement structure which is encountered with one particular type of composite material, namely a twill 2/2 carbon fibre weave with an epoxy matrix.

Published: November 2015

This paper presents two new technologies in order to optimize the operation of a con-ventional spring-damper-system. Therefore, the function structure such as the energy flow of a con-ventional system is investigated and optimized. The first resulting technology is the fluid dynamicabsorber (FDA) which is still a passive solution and improves the energy flow of the conventionalspring-damper-system with the help of an absorber with a hydraulic transmission. The second tech-nology is the active air spring damper (AASD) which is an active variant of a spring-damper-systemand optimizes the energy flow by using electrical energy. We use a quarter car model to examine theperformance of our technologies and compare them in the conflict diagram where driving comfort vs.driving safety is shown within the scope of uncertainty. The FDA improves the driving safety at almostthe same comfort. The driving comfort is improved by using the AASD. We also examine the systembehavior at uncertain loads. The results show that they are capable of controlling this uncertainty.

Authors: Pop Grigore Marian , Steopan Mihai , Conțiu Glad , Popescu Adrian
Published: November 2015

In this paper, an attempt has been made to model the surface roughness through response surface method (RSM) and ANOVA when drilling CFRP composites. Drilling is the most common machining process applied to CFRP. However, the users of this kind of composites are facing difficulties to machining it, due to its properties. Because of the bad effects that lubricants have on the fiber-reinforced composites, the machining of these materials is performed without coolant. On the other hand dry machining offers the risk of a thermal damage induced by high process temperatures. The current experimental analysis is focused towards determining process temperatures with different tools and drilling parameters.

Innovation and Corporate Social Responsibility in SMEs
Authors: Feniser Cristina , Lungu Florin
Published: November 2015

So far little attention has been given the differences or the compatibilities between CSR and innovation. Few works treats CSR in combination with innovation. What exactly is the relationship between CSR and innovation? Recent phenomena such as open innovation is based on the concept that the stakeholder's dialogue that overlaps with some dimensions of CSR. Being innovative means to bring organizational and technical improvements which will translate into a better position in the market. These improvements don't just aim the product, but the process by which it is obtained and its whole life-cycle. We're talking about a new approach to innovation, namely its orientation towards sustainability. Although SMEs have many features which facilitate implementation of CSR, activities of this type in such organizations are still limited. SMEs managers often make choices that are related to rational management. This leads to divergence between economical and social goals. Through a qualitative exploration of the concepts of CSR and innovation, we wanted to find out from some managers whether there is a link between innovation and CSR in SMEs and whether the activities corresponding to the two concepts overlap in a certain measure.

Authors: Bodi Ştefan , Dragomir Mihai , Banyai Daniel , Dragomir Diana
Published: November 2015

This paper presents a case study both for individual process improvements and also for the improvement of the overall manufacturing flow, within an SME, using specialized simulation software called SigmaFlow Modeler. The improvements are done based on simulation results (accurate knowledge), meaning that by analyzing the process distribution charts, one can dispose measures for solving problems or even preventing potential failures. It has to be noted that by eliminating those bottlenecks the overall performance of the process will increase and the manufacturing flow will also be enhanced. The paper will also present an actual process simulation for the most complex process from the manufacturing cycle, i.e. the milling process, and a short analysis, focusing on possible improvements, will be performed on it. Moreover, further improvements will be done by closely reviewing and identifying every input and output and by introducing them into a cause-and-effect matrix, the importance of each input can be mathematically calculated and action can be taken for the critical ones in order to improve the process.

The Anti-Factor Xa Range for Low Molecular Weight Heparin Thromboprophylaxis
Authors: Wei Matthew Y. , Ward Salena M.
Published: November 2015

Low molecular weight heparins (LMWHs) are now the mainstay option in the prevention and treatment of venous thromboembolism. In some patients receiving therapeutic doses of LMWH, activity can be measured by quantifying the presence of Anti-factor Xa (AFXa) for dose adjustment. However, currently there are no guidelines for LMWH monitoring in patients on thromboprophylactic, doses, despite certain patient populations may be at risk of suboptimal dosing. This review found that while the AFXa ranges for therapeutic levels of LMWHs are relatively well defined in the literature, prophylactic ranges are much less clear, thus making it difficult to interpret current research data. From the studies published to date, we concluded that a reasonable AFXa target range for LMWH deep venous thromboses prophylaxis might be 0.2–0.5 IU/mL.

Fifth generation seismic hazard model for Canada: grid values of mean hazard to be used with the 2015 National Building Code of Canada
Authors: Halchuk S C , Adams J E , Allen T I
Published: November 2015

Canada's 5th Generation seismic hazard model is the basis for the seismic design provisions in the 2015 National Building Code of Canada. The 2015 code uses mean ground motion on firm soil sites for a probability of exceedance of 2% in 50 years, with the
ground motion being described by seismic hazard values for eight parameters: spectral acceleration at 0.2, 0.5, 1.0, 2.0, 5.0 and 10.0 second periods, peak acceleration and peak velocity. We tabulate values of the eight parameters and for three additional spectral periods (0.05, 0.1 and 0.3 seconds)
for more than 200,000 grid points over Canadian territory and surrounding areas. Values at eight probability levels are provided. The spectral parameters will allow the construction of approximate uniform hazard spectra and hazard curves for every locality in Canada, and hence provide necessary
information for earthquake-resistant design.
Glissements de terrain et chemins de fer dans la vallée de la rivière Thompson, en Colombie-Britannique
Authors: Huntley D H
Published: November 2015

Landslides in the mountain valleys of western Canada have challenged the development and operation of railways since the late 19th Century. In the 21st Century, pronounced economic and environmental repercussions occur when rail service is disrupted by landslide
activity. In the section of the Canadian National and Canadian Pacific railway corridor that runs through the Thompson River valley in southern British Columbia there is a unique combination of complex glacial geology and active slope processes. To better understand and manage geological hazards and
risks along this section of the transportation corridor, a small slow-moving landslide that is adversely impacting critical railway infrastructure and operation is now under collaborative investigation by the national railway companies, federal government agencies and universities through the
Railway Ground Hazard Research Program http://www.carrl.ca/RGHRP. Radar satellite imagery, global positioning, borehole monitoring, fiber optical measurement of slope deformation, geological mapping, geophysical surveys and field observations provide information on the distribution of earth
materials, landforms and deformation processes involved in the landslide. All techniques confirm movement across the main landslide body, with the greatest displacement at the south end in the vicinity of a lock-block retaining wall. Mapping and geophysical surveys indicate a high relief bedrock
surface overlain by up to 80 metres of clay, till and gravel with saline groundwater in the main body and landslide toe. Planar sub-surface features revealed in geophysical profiles include tabular bedding and earth material contacts. Profiles also show discrete curvilinear features interpreted as
retrogressive translational failure planes in clay-rich layers beneath the retaining wall and rail ballast that extend below the Thompson River. Innovative research and development at this site provides national railway companies, governments and local communities with better information to predict
landslide movement and reduce risks to the environment, economy, natural resources and public safety. The painting is a southward view of the Thompson River valley showing bedrock, glacial deposits, scattered boulders, landslide scarps, radar satellite monitoring prisms and global positioning
stations flanking the rail tracks and retaining wall at the Ripley Landslide, near Ashcroft in south-central British Columbia. About the artist: Dr. David Huntley is a research scientist with the Geological Survey of Canada.
2-row Springer Fibres and Khovanov
Diagram Algebras for Type D
Authors: Ehrig Michael , Stroppel Catharina
Published: November 2015

We study in detail two row Springer fibres of even orthogonal type from an algebraic as well as a topological point of view. We show that the irreducible components and their pairwise intersections are iterated ℙ1-bundles. Using results of Kumar and Procesi we compute the cohomology ring with its action of the Weyl group. The main tool is a type D diagram calculus labelling the irreducible components in a convenient way that relates to a diagrammatical algebra describing the category of perverse sheaves on isotropic Grassmannians based on work of Braden. The diagram calculus generalizes Khovanov's arc algebra to the type D setting and should be seen as setting the framework for generalizing well-known connections of these algebras in type A to other types.
High Order Finite Difference Discretization for Composite Grid Hierarchy and Its Applications
Authors: Gu Qun , Gao Weiguo , García-Cervera Carlos J.
Published: November 2015

We introduce efficient approaches to construct high order finite difference discretizations for solving partial differential equations, based on a composite grid hierarchy. We introduce a modification of the traditional point clustering algorithm, obtained by adding restrictive parameters that control the minimal patch length and the size of the buffer zone. As a result, a reduction in the number of interfacial cells is observed. Based on a reasonable geometric grid setting, we discuss a general approach for the construction of stencils in a composite grid environment. The straightforward approach leads to an ill-posed problem. In our approach we regularize this problem, and transform it into solving a symmetric system of linear of equations. Finally, a stencil repository has been designed to further reduce computational overhead. The effectiveness of the discretizations is illustrated by numerical experiments on second order elliptic differential equations.
A comparative study of the morphology of mammalian true chordae tendineae of the atrioventricular valves
Authors: Hutchison J. , Rea P.
Published: November 2015

Introduction: There is little literature on the subvalvular apparatus of the atrioventricular valves' of the heart. This investigation aimed to compare mammalian atrioventricular valve subvalvular apparatus; in particular the number and characteristics of true chordae tendineae (TChT) and their tissue transition areas - proximally with the valve leaflets, and distally with the papillary muscles. Materials and Methods: Sheep, pig and bovine fresh hearts were dissected (n = 9). The subvalvular apparatus of the mitral and tricuspid valves were visualised. Each TChT origin was grouped and counted according to papillary muscle and valve, and compared within and across the species. Appropriate statistical analyses were then applied to identify any correlations. Histological examination of the transition areas was also performed. Results: The tricuspid valve had significantly more TChT than the mitral (p = 0.04). On comparison of the TChT counts in both valves across the species, there were no signiicant differences. An unexpected inding was the abrupt transition from chordae collagen to papillary muscle. Conclusion: The tricuspid valve is under less pressure than the mitral but is connected to significantly more TChT. We have shown no significant difference between the numbers of TChT for each papillary muscle in either mitral or tricupsid valves across the species. Veterinary teaching emphasises that there is no clinically signiicant difference at a gross morphology level between these species. This is the irst study to report that there is also no signiicant difference at the subvalvular level, and this has direct translational relevance for bioprosthetic cardiac valve replacement.
GFIT2: an experimental algorithm for vertical profile retrieval from near IR spectra
Authors: Connor B. J. , Sherlock V. , Toon G. , Wunch D. , Wennberg P.
Published: November 2015

Abstract. An algorithm for retrieval of vertical profiles from ground-based spectra in the near IR is described and tested. Known as GFIT2, the algorithm is primarily intended for CO2, and is used exclusively for CO2 in this paper. Retrieval of CO2 vertical profiles from ground-based spectra is theoretically possible, would be very beneficial for carbon cycle studies and the validation of satellite measurements, and has been the focus of much research in recent years. GFIT2 is tested by application both to synthetic spectra, and to measurements at two TCCON sites. We demonstrate that there are approximately 3° of freedom for the CO2 profile, and the algorithm performs as expected on synthetic spectra. We show that the accuracy of retrievals of CO2 from measurements in the 1.6 μ spectral band is limited by small uncertainties in calculation of the atmospheric spectrum. We investigate several techniques to minimize the effect of these uncertainties in calculation of the spectrum. These techniques are somewhat effective, but to date have not been demonstrated to produce CO2 profile retrievals superior to existing techniques for retrieval of column abundance. We finish by discussing on-going research which may allow CO2 profile retrievals with sufficient accuracy to significantly improve on the results of column retrievals, both in total column abundance and in profile shape.
Technical Note: Sampling and processing of mesocosm sediment trap material for quantitative biogeochemical analysis
Authors: Boxhammer T. , Bach L. T. , Czerny J. , Riebesell U.
Published: November 2015

Abstract. Sediment traps are the most common tool to investigate vertical particle flux in the marine realm. However, the spatial decoupling between particle formation and collection often handicaps reconciliation of these two processes even within the euphotic zone. Pelagic mesocosms have the advantage of being closed systems and are therefore ideally suited to study how processes in natural plankton communities influence particle formation and settling in the ocean's surface. We therefore developed a protocol for efficient sample recovery and processing of quantitatively collected pelagic mesocosm sediment trap samples. Sedimented material was recovered by pumping it under gentle vacuum through a silicon tube to the sea surface. The particulate matter of these samples was subsequently concentrated by passive settling, centrifugation or flocculation with ferric chloride and we discuss the advantages of each approach. After concentration, samples were freeze-dried and ground with an easy to adapt procedure using standard lab equipment. Grain size of the finely ground samples ranges from fine to coarse silt (2–63 μm), which guarantees homogeneity for representative subsampling, a widespread problem in sediment trap research. Subsamples of the ground material were perfectly suitable for a variety of biogeochemical measurements and even at very low particle fluxes we were able to get a detailed insight on various parameters characterizing the sinking particles. The methods and recommendations described here are a key improvement for sediment trap applications in mesocosms, as they facilitate processing of large amounts of samples and allow for high-quality biogeochemical flux data.

Abstract. Sea surface temperature (SST) and turbidity (T) derived from Landsat 8 (L8) imagery were used to characterize river plumes in the northern Adriatic Sea (NAS) during a significant flood event in November 2014. Circulation patterns and sea surface salinity (SSS) from an operational coupled ocean-wave model supported the interpretation of the plumes' interaction with the receiving waters and among them. There was a good agreement of the SSS, T, and SST fields at the sub-mesoscale and mesoscale delineation of the major river plumes. L8 30 m resolution also enabled the description of smaller plume structures. The different plumes' reflectance spectra were related to the lithological fingerprint of the sediments in the river catchments. Sharp fronts in T and SST delimited each single river plume. The isotherms and turbidity isolines' coupling varied among the plumes due to differences in particle loads and surface temperatures in the discharged waters. The surface expressions of all the river plumes occurring in NAS were classified based on the occurrence of the plume dynamical regions in the L8 30 m resolution imagery.
Multi-method observation and analysis of an impulse wave and tsunami caused by glacier calving
Authors: Lüthi M. P. , Vieli A.

Abstract. Glacier calving can cause violent impulse waves which, upon landfall, can lead to destructive tsunami-like waves. Here we present data acquired during a calving event from Eqip Sermia, an ocean-terminating glacier in West Greenland. During an exceptionally well documented event, the collapse of 9 × 105 m3 ice from a 200 m high ice cliff caused an impulse wave of 50 m height, traveling at a speed of 25–30 m s-1. This wave was filmed from a tour boat in 800 m distance from the calving face, and simultaneously measured with a terrestrial radar interferometer and a tide gauge. Tsunami wave run-up height on the steep opposite shore in 4 km distance was 10–15 m, destroying infrastructure and eroding old vegetation. These observations indicate that such high tsunami waves are a recent phenomenon in the history of this glacier. Analysis of the data shows that only moderately bigger tsunami waves are to be expected in the future, even under rather extreme scenarios.
Which Emotion(s) Mediate the Relationship Between Mental Illness and Trust?
Authors: Rice Stephen , Kraemer Keegan , Mehta Rian
Published: November 2015

Previous literature has shown that the stigma of mental illness can have serious negative effects on trust ratings in the person suffering from the illness. Furthermore, prior studies have shown that general affect (emotions) mediate the relationship between mental illness stigma and trust; that is, people trust those with mental illness less because they feel more negatively towards them. The current study expands on these findings by analyzing specifically which emotions mediate this relationship, and how strong that mediation effect is. We used Ekman and Friesen’s (1971) six universal facial expressions of emotions to test this missing gap in the literature. In two studies, participants were presented with a target individual who had severe and chronic depression (versus a control group) and asked to provide ratings of affect and trust in the target individuals. In Study 1, we replicated a previous finding that general affect mediates the relationship between mental illness and trust. In Study 2, we found that of the six universal emotions, only Happiness had a significant mediating effect on the relationship between mental illness and trust. We discuss the theoretical, practical and methodological implications of this data.
The Introduction of The Adventures of Tom Sawyer to the Students of Independent University, Bangladesh, to Develop Their Reading Habit
Authors: Zabeen Saara
Published: November 2015

In today's world a student's free time is taken over by fruitless recreations. They hardly read anything other than their text messages. In order to encourage their reading habit the students of the English Reading Skills course were assigned to read Mark Twain's The Adventures of Tom Sawyer. This paper will focus on the matter how the particular book had been an appropriate choice to encourage the students to read additional material. After the completion of the project it was found that the students not only got acquainted with Mark Twain but also enjoyed the contents of the book, as they could relate their adolescence (which they had just left behind) with the acts of Tom in the book. This project surely encouraged extensive reading among the students.
Quarry Farm and the Afterlife
Authors: Webb Steve
Published: November 2015

“Quarry Farm and the Afterlife” is a brief sketch drawn with the information and observations I've absorbed while living in the house that has often been described by Twain scholars as the “spiritual mecca” of the author's work and life. The medium I've chosen for this “sketch” was inspired by the one question I am asked over and over: “Are there any ghosts?” The purpose of this essay is to recount, to the best of my ability, all spiritual interactions I have experienced as well as the intercommunications of visiting scholars with the fourth dimension as they've recollected to me. In conclusion I've determined that I—or any other living human being on the planet—am not qualified to answer questions regarding the existence of alternate dimensions and their inhabitants; I am only qualified, as I have done, to draw a picture, theorize, and allow the reader to decide.

Research on Geometrical Patterns on Yao Nationality Clothing
Authors: Rong Ting
Published: November 2015

The Yao nationality has a long history, splendid Civilizations, numerous sub-lines and clothing in riotous profusion. Among which, the greatest characteristic is various geometrical patterns on Clothing. This essay divides geometrical patterns onYaonationality clothing into patterns with pure ides forms simply formed by point, line and surface; patterns formed by highly abstract generalization through imitation and symbolization to natural objects and man-made objects; and patterns represent historic Civilization and religious belief ofYaonationality. On this basis, this essay analyzes constitution forms of geometrical patterns onYaonationality clothing, summaries the ornament position on clothing and technology embodiment of these patterns. In the end, this essay tries to discuss their forming reasons and historic embodiment.

Published: November 2015

Shrimp cultivation has spread out rapidly in coastal Bangladesh. Secondary literatures provides the evidence that to afford an alternative way of livelihood for the locals, shrimp cultivation extended widely throughout the coastal areas of Bangladesh. But, the extension of shrimp farming is unable to create work opportunity for the locals in true sense. In this research, by using a household survey, to know their basic demographic information, it is revealed that though 80% of the household heads main occupation is fishing and related works but only 0.71% of their main source of fishing is shrimp farm. Moreover, in-depth interviews and Focus Group Discussions disclose that shrimp cultivation of this village is controlled and retained by the rich and outside investors, not by the poor locals. This research discovered that man-made disasters, along with the natural disasters are equally responsible in generating vulnerability from shrimp cultivation.
