Reducing environmental hazards through reserve supply chain model

Environmental hazards transpire when industrial wastages are dumped illegally into vacant lands, rivers or low-lying areas. This is a major problem in developing, and less-developed countries where environmental regulations are not (or cannot be) strictly enforced. Researchers around the globe are conducting research to find various ways to minimize or eliminate industrial hazards. In this paper, we take a supply-chain approach and show how the concept of the reverse supply chain can be used to recycle industrial wastage into useful by-products. Our problem domain is poultry industry in Bangladesh. Using Simul8, a simulation model of reverse supply chain is developed for a large poultry plant in Bangladesh where poultry wastes are modelled to turn into various by-products. We use primary and secondary data to run the simulation model. Our results show that poultry wastes can indeed be processed to turn into various by products as bakery products, biogas, artificial charcoal, etc. The management of the poultry plant can use our results to develop policies to reduce poultry hazards and thus save the environment. We touch on research and managerial implications of our results

The focuses on environment and reverse supply chain have increased in recent years among academic and industry circle. Yet, Bangladesh poultry is to achieve environmental sustainability in her extended forward and reverse supply chain. In this paper, supply chain model developed based on a case poultry industry. Design science and case method under positivist and quantitative paradigm followed to develop simulation model using simul8 application to fit the real poultry case. The objectives of this paper are to review literature, develop simulation supply chain model and later tested it through historic data. The results briefly discussed and model capturing the relationship among forward, reverse and mainstream supply chain of the case. Different random trial runs of the simulation model have shown in the result section to find out optimality

Compressive, tensile and thermal properties of epoxy grouts subjected to underwater conditioning at elevated temperature

Oil and gas pipes are susceptible to failure initiated by corrosion due to their operating pressure under adverse atmospheric conditions. Repairs, comprising a composite shell assembled around the pipe with a small gap, which is then infilled with grout, are considered a suitable option for corroded pipelines. This paper presents the investigation on the mechanical (compression, tension) properties and glass transition temperatures of two infill grouts, after 1000 hour of hot/wet conditioning. An extended investigation on the moisture absorption behaviour was also carried out, revealing the highest absorption to be about 6% after 2520 hours of immersion. The glass transition temperatures of the grouts are reduced by approximately 20ºC. The results suggest that the grouts underwent significant reduction of strength and stiffness due to hot/wet conditioning when tested at an elevated temperature, compared to room temperature. This reduced strength and stiffness is the result of the grouts being tested in close proximity to their glass transition temperatures

Effects of flowering behavior and pod maturity synchrony on yield of mungbean [Vigna radiata (L.) Wilczek].

A number of experiments were set up to assess the flower production and flowering pattern in synchrony with pod maturity and seed yield in twelve mungbean genotypes. Synchrony of pod maturity was measured based on percentage of mature pods at first harvest, where; synchrony (>90% mature pods), partial synchrony (80-90% mature pods) and asynchrony (<80% mature pods). Results revealed that genotypes that produced maximal opened flowers within 10-15 days, and ceased flowering within 15-20 days after first flowering (DAF), have synchrony in pod maturity. Additionally, seed yield was strongly correlated with the number of opened flowers and number of produced mature pods. Four genotypes showed synchrony in pod maturity which accompanied with cessation of flower production at 10-15 DAF, but produced lower yields due to fewer opened flowers. In contrast, the remaining genotypes showed partial synchrony or asynchrony in pod maturity due to longer flowering durations, with higher number of opened flowers and seed yield. These results indicate that synchrony in pod maturity and seed yield in mungbean is inversely related

Bureaucratic behaviour, and its influence towards competitiveness – analysing the supply chain of Bangladeshi clothing industry

Distribution systems are becoming increasingly complex and dynamic in business in the consumer market of clothing or Readymade Garments (RMG) products. There are many exterior influencing elements like political action (PA), country risk (CR), and bureaucratic behaviours (BB) that are influencing the clothing supply chain and posing threats to its competitiveness. A research question has developed to know how BB activities affect competitiveness. Based on this research question, this research aims to determine BB’s influence on the competitiveness of the clothing supply chain. Stakeholder philosophies and resource dependence theory have been considered to develop a hypothesis in this study. The Quantitative research method was applied in this study. The data were collected through a field survey. Partial Least Squire (PLS) based Structural Equation Modelling (SEM) was used to analyse collected data. Seven hypotheses were developed in this research. Among them, five hypotheses are supported, and two hypotheses are not supported. In addition, mediation test results are not reflected as positive. The findings are discussed in detail in the discussion and implementation part of this study. The clothing (RMG) industry of Bangladesh could implement the result to improve competitiveness

Effect of Organic and Inorganic Fertilizer on the Growth and Yield of Rice (Oryza sativa L.)

Abstract: Combination of organic and inorganic sources of nutrients is necessary for sustainable agriculture that can ensure food production with high quality. In order to study the effect of vermicompost and chemical fertilizers on the growth and yield components in rice, an experiment was carried out during December 2013 to June 2014, in randomized block design based on 3 replications. The treatments of vermicompost were given in 4 levels (0.0, 1.0, 2.0 and 4.0 t ha -1 ) and 4 levels of chemical fertilizers (0-0-0-0, 50-8-33-6, 100-16-66-12 and 150-24-99-18 kg N, P, K and S ha -1 , respectively). Different levels of vermicompost and NPKS fertilizers showed significant effect on growth, yield and yield contributing characters of BRRI dhan29. Results showed that application of medium level of chemical fertilizer with 4 t ha -1 vermicompost gave the maximum yield. It was observed that over dose of NPKS fertilizers from chemical source decreased rice yield. Results also revealed that the highest plant height, effective tillers hill -1 , flag leaf length, panicle length, filled grains panicle -1 , 1000-grain weight, grain yield, straw yield and biological yield were obtained from the combination of 4 t ha -1 vermicompost with 100 kg ha -1 N, 16 kg ha -1 P, 66 kg ha -1 K, 12 kg ha -1 S. It was observed that yield of rice can be increased substantially with the judicious application of organic fertilizer with chemical fertilizer

Integrated effects of marketing stimuli on customer loyalty in Palestine grocery supply-chain: does satisfaction perform mediating role?

Grocery stores are a crucial connection in the food delivery system and a fundamental component of the retail industry. Some grocery stores have worked with regional suppliers to benefit the community and the consumer. Palestinian market is uncommon because clients have connected what they manufacture and sell under particular circumstances. This study is, therefore, an integrated examination of the critical influencing factors on the marketing of food products in Palestine. A survey questionnaire was used. An organised, self-administered survey was used to acquire data, and analysis techniques were outlined using Structural Equation Modelling (SEM). According to the findings, relationship marketing and service quality are the crucial brand strategy factors influencing customers’ decisions to purchase groceries and showing how happy and devoted they are to grocery stores. The Palestinian government has greatly benefited from the results of this study of how consumers perceive essential factors that may be considered when formulating future regulations about food and other grocery items

Planning “Exceptionalism”? Political Economy of Climate Resilient Development in Bangladesh

Following three major disasters in 2007, Bangladesh intensified its effort to tackle climate change through development of the Bangladesh Climate Change Strategy and Action Plan (BCCSAP). The process of plan formulation led to debates nationally and internationally regarding the financing and integration of climate change into development planning. Using a political economic lens, this article illustrates how major national initiatives around international problems must be understood in terms of the interplay of actors, their ideas and power relations. The article argues that: (a) power relations among actors significantly influenced the selection of ideas and implementation activities; (b) donor concerns around aid effectiveness and consequent creation of parallel mechanisms of planning and implementation may run counter to both the mainstreaming process and the alignment of assistance with country priorities and systems; (c) climate change planning processes must be opened up to include actors from across sectors, population groups and geographical areas

An overview of burst, buckling, durability and corrosion analysis of lightweight FRP composite pipes and their applicability

© 2019 Elsevier Ltd. All rights reserved.The main aim of this review article was to address the performance of filament wound fibre reinforced polymer (FRP) composite pipes and their critical properties, such as burst, buckling, durability and corrosion. The importance of process parameters concerning merits and demerits of the manufacturing methods was discussed for the better-quality performance. Burst analysis revealed that the winding angle of ±55° was observed to be optimum with minimum failure mechanisms, such as matrix cracking, whitening, leakage and fracture. The reduction of buckling effect was reported in case of lower hoop stress value in the hoop to axial stress ratio against axial, compression and torsion. A significant improvement in energy absorption was observed in the hybrid composite pipes with the effect of thermal treatment. However, the varying winding angle in FRP pipe fabrication was reported as an influencing factor affecting all the aforementioned properties. Almost 90% of the reviewed studies was done using E-glass/epoxy materials for the composite pipe production. By overcoming associated limitations, such as replacing synthetic materials, designing new material combinations and cost-benefit analysis, the production cost of the lightweight FRP composite pipes can be decreased for the real-time applications.Peer reviewe
