ABSTRACTThe main purpose of Green Supply Chain Management (GSCM) is to improve the quality of supply chain management strategies and environmental performance. As per current statistics, the chemical industry is growing fast in Bangladesh. In order to compete for global competition, GSCM is essential in this sector. This paper proposes a systematic approach of structural framework whose aim is to enhance the probability of constructive implementation of GSCM in the field chemical industry in Bangladesh. Therefore, this framework evaluates the appropriate interrelationship along with the drivers of GSCM in the chemical industry. In total, eight drivers were finalized from an associated literature review with the help of survey and by taking expert opinions via the Delphi methodology. In addition to MICMAC analysis, the driving and the dependence powers for all the drivers were determined. Moreover, the structural frameworks for the drivers were developed by means of total interpretive structural modeling (TISM) technique. As a result, the findings indicate that the most significant driver was supplier pressure and willingness and the most important barrier was high cost. Finally, the main objective of this research is expected to help industrial managers to evaluate and understand the critical areas where they should emphasize to implement GSCM in the chemical industry. 相似文献

The effects of weathering on the constituents of wood and polymer matrix behavior in wood plastic composites (WPCs) were investigated.
WPCs were produced from pine, extractives-free pine, and pine holocellulose fibers (60%) together with HDPE (40%). These composites
were subjected to xenon-arc accelerated and outside weathering for a total of 1200 h and 120 days, respectively. The color
and chemical changes that occurred on the surface of the WPCs were analyzed using a set of analytical techniques. For pine
and extractive-free pine filled composites, the results showed that the total color change, lightness, and oxidation increased,
while the lignin content decreased. In addition, the weight average molecular weight (Mw) and number average molecular weight (Mn) of extracted HDPE decreased with an increase in exposure time of the composites. However, HDPE crystallinity increased with
longer exposure time. Lightness of holocellulose-based WPC changed the least while the change in its HDPE crystallinity was
not significant compared to the other composite types. Therefore, holocellulose-based WPC may be preferred for applications
where color stability is of high priority. 相似文献

The potential impacts of land use on large woody debris (LWD) were examined in Sourdough Creek Watershed, a rapidly growing
area encompassing Bozeman, Montana, USA. We identified six land classes within a 250 m buffer extending on either side of
Sourdough Creek and assessed aquatic habitat and geomorphologic variables within each class. All LWD pieces were counted,
and we examined 14 other variables, including undercut bank, sinuosity, and substrate composition. LWD numbers were generally
low and ranged from 0 to 8.2 pieces per 50 m of stream. Linear regression showed that LWD increased with distance from headwaters,
riparian forest width, and sinuosity in four of the six land classes. Statistically significant differences between land classes
for many aquatic habitat and geomorphologic variables indicated the impacts of different land uses on stream structure. We
also found that practices such as active wood removal played a key role in LWD abundance. This finding suggests that managers
should prioritize public education and outreach concerning the importance of in-stream wood, especially in mixed-use watersheds
where wood is removed for either aesthetic reasons or to prevent stream flooding. 相似文献

Problem
Falling is a leading cause of serious injury, loss of independence, and nursing-home admission in older adults. Impaired balance control is a major contributing factor.Methods
Results from our balance-control studies have been applied in the development of new and improved interventions and assessment tools. Initiatives to facilitate knowledge-translation of this work include setting up a new network of balance clinics, a research-user network and a research-user advisory board.Results
Our findings support the efficacy of the developed balance-training methods, balance-enhancing footwear, neuro-prosthesis, walker design, handrail-cueing system, and handrail-design recommendations in improving specific aspects of balance control.Impact on Knowledge Users
A new balance-assessment tool has been implemented in the first new balance clinic, a new balance-enhancing insole is available through pharmacies and other commercial outlets, and handrail design recommendations have been incorporated into 10 Canadian and American building codes. Work in progress is expected to have further impact. 相似文献
