A Pragmatic Study on Viral Marketing Scenario of Bangladesh

Viral marketing is today's electronic equivalent of old-fashioned word of mouth marketing. In present circumstance, this marketing system may be the most time and cost effective tool for building long term relationship with the customers. The paper aims to identify and analyze the overall system of viral marketing exist in Bangladesh to access the present scenario of this country. At first the study used qualitative approaches to illustrate what viral marketing system (VMS) actually is. The study also attempted to highlight the issues associated with the viral marketing system like significance, classifications, tools, strategies and present situation of Bangladesh. After attaining deeper understanding about VMS through qualitative approaches, the study used quantitative approaches and in this case the primary data has been collected from 100 respondents through survey method. Bangladesh has huge potentials in case of viral marketing system development. But this nation needs to ascertain the scope through development of sufficient technological awareness and internet capacity. Keywords: Viral marketing system, internet marketing, social network marketing system, virtual community and online communication system

Effect of kenaf and EFB fiber hybridization on physical and thermo-mechanical properties of PLA biocomposites

Kenaf/empty fruit bunch/polylactic acid (kenaf/EFB/PLA) hybrid biocomposites were prepared using hot press technique. The ratio of fiber to polylactic acid was set at 60:40 with 1:1 ratio between kenaf and empty fruit bunch fibers. Physical, mechanical and thermal properties of hybrid biocomposites were subsequently characterized using Fourier transform infrared spectroscopy, scanning electron microscope, X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, tensile and water absorption tests. Test results indicated that mechanically stronger fiber was able to support the weaker fiber. Hybrid fiber biocomposite had higher crystallinity as compared to single fiber biocomposite. Water absorption of hybrid composite was higher as compared to single fiber composite. Thermal result revealed that hybridization of fiber was not significantly influence the thermal properties of composites. However, the presence of two different fibers proposed good wettability properties, which could reduce the formation of voids at the fibers-polymer interface and produce composites with high stiffness and strength
