The Green ring is a powerful mathematical tool used to codify the interactions between representations of groups and algebras. This ring is spanned by isomorphism classes of finite-dimensional indecomposable representations that are added together via direct sums and multiplied via tensor products. In this thesis, we explore the Green rings of a class of Hopf algebras that form an extension of the Taft algebras. These Hopf algebras are pointed and coserial, meaning their simple comodules are 1-dimensional, and their comodules possess unique composition series respectively. The comodules of these Hopf algebras thus have a particularly well-behaved structure. We present results giving structure to the comodule Green ring of the Hopf algebra Hs and in particular fully classify the Green rings of Hs where s ≤ 6. More generally, we classify the indecomposable comodules of Hs and their composition series and prove how the composition series may be used to classify the tensor product of indecomposable comodules. Additionally, for these Hopf algebras we classify the Grothendieck rings, the subrings of the corresponding Green rings consisting only of isomorphism classes of projective indecomposable comodules. We describe a simpler presentation of these Grothendieck rings and the multiplication in the ring.

Studies of vocalizations in a montane population of Green-Tailed Towhees were conducted during the summer months of 1971 and 1972 in Cache County, Utah. The song and call repertoiries of 10 breeding pairs were recorded and analyzed on a sound spectograph. Males averaged 8.7 different song and 18.2 different not types. Song variation on the population level is high (58 different songs) but the sharing of these songs among the males is low (22.4) . Populational note structure is equally diverse but reveals a greater degree of sharing (75%). Both males and females used three calss, the meow, tick, and poitt, whereas at least three more, the rattle, tst-tst-tst, and skee-skee-skee, are used only by the female. Recoginition of the songs of conspecifies apparently is promoted by the distinctive introductory note, the duration of the song and the abruptness of changes within it.

This thesis is a subtask of the research project “Green Production System”, which is jointly launched and run by Volvo/Volvo Technology, Haldex, Saab and All-Emballage J.E. AB as industrial party, and Mälardalen University as academic party. The whole project is dedicated to develop “green production system” to be a competitive mean to Swedish automotive and manufacturing industry through four work packages, which are “Wet preconditions and frames of a green production system”, “Visualization of environmental impact and added value”, “Development and implementation of tools for green control and management” and “Development of guidelines for environmental value improvement and cost decrease” respectively. And this thesis is an effort to package 2. Value stream mapping is assumed to be a potentially effective tool to be developed for visualizing environmental wastes produced by production processes. Thereby, the focus of this thesis is on the transformation of VSM into EVSM (Environmental Value Stream Mapping). By reviewing literature, the reduction of environmental wastes is additionally counted into a characteristic of lean production. Meanwhile, seven environmental wastes are identified and defined. The development of EVSM is on an absolutely great degree based on the identification and measurement of environmental wastes. Thus, waste measurement and production data collection are supposed to be the prerequisite of EVSM implementation. In order to verify the supposition, a test practice was carried out in CH Industry AB, which is a metal processor. After the practical study, CH’s incompetence of working on EVSM is analysed, and advice is proposed. At the end of thesis, analysis of EVSM is made in terms of its prerequisite, difference from VSM, pros and cons, etc. In addition, suggestions for further research are given.

In today’s world Lean and Green are becoming essential components of the supply chain. The thesis tries to contribute to a further understanding of the supply chain management, lean, green and their integration. The basic concepts and the research contributions of various authors are briefed in the theoretical framework made for a better understanding to the readers. Having gained the relevant theoretical knowledge, the interview questions are framed and case companies are analyzed for their lean and green activities in their supply chain. The empirical data collected from the case companies through interviews and surveys are projected. With the empirical results and the relevant theoretical results, an analysis & discussion is made which explicitly gives the implications of lean and green over the supply chain and their associated practical scenarios. The outcome and the findings are used to construct a model which depicts the relationship between lean, green and their influence over the supply chain. Influence on the supply chain by lean and green are projected independently in the lean supply chain model and green supply chain. The Integrated lean and green model illustrates the relationship and influence between lean, green and supply chain factors. This model also serves as a prototype for the industries to make their own indigenous integrated model. Further, outcome that how lean and green improves the supply chain and the lean and green integrated model are summarized in the conclusion. In a bird’s eye view, this research thesis work is a contribution to lean, green and their integration which explicitly shows the ways that lean, green improves the supply chain performance and  provides a framework / prototype model for lean and green integration for the industries.

With greater calls for environmental protection worldwide, countries have implemented rules such as RoHS, EuP, WEEE and REACH to regulate components of product materials and chemicals. Taiwanese firms should actively promote environmental protection and coordinate suppliers in various regions so as to improve green supply chain performance given that firms in supply chain are located around the world. This study, using qualitative interview, interviewed 7 leading Taiwanese companies that actively promote green supply chain and listed integration and coordination mechanisms often used. Integration and coordination of green supply chain used in Taiwan included: (1) setting up units responsible for promoting greening; (2) holding supplier meeting; (3) audit system of suppliers; (4) establishment of inter-departmental unit; (5) training for suppliers; (6) assisting suppliers; and (7) setting up information-sharing system. Location in supply chain, supply chain relationship and industry sectors determine uses and varieties of integration and coordination of green supply chain. They are as follows: 1.Location in supply chain: downstream firms have more and often use integration and coordination of green supply chain than upstream ones. 2.Supply chain relationship: central factories have more and often use integration and coordination of green supply chain than satellite ones. 3.Industry sectors: emerging strategic industries have more and often use integration and coordination of green supply chain than traditional ones.

This study develops two researches to examine the influence of green concept on performance. The research I focuses on firm level. The research II focuses on consumer level. In the research I, the results show that (1) green learning-orientation is positively associated with proactive green innovation capability, (2) green learning-orientation is positively associated with firm performance, and (3) proactive green innovation capability is positively associated with firm performance. Thus, companies that are pioneers in green learning have the ability to enhance their innovation capability in terms of processes, products, and services and increase their performance. Additionally, proactive green innovation capability is also an important source of performance. In the research II, the results show that (1) green product quality is positively associated with green customer satisfaction and green customer loyalty; (2) green corporate image is positively associated with green customer satisfaction and green customer loyalty; and (3) green customer satisfaction is positively associated with green customer loyalty. The results indicate that green product quality can bring about green customer satisfaction and green customer loyalty. Additionally, green corporate image can contribute to green customer satisfaction and green customer loyalty.

The present study was carried out to examine the chemopreventive effects of curcumin and green tea polyphenols on the hamster cheek pouch carcinogenesis model. This model of oral carcinogenesis has been widely used in chemoprevention studies, however, these studies have been limited to the use of DMBA as the carcinogenic agent. We have developed a protocol of carcinogenesis in the hamster cheek pouch using B[a]P, a broadly distributed environmental carcinogen, formed as a by-product of the combustion of organic materials including cigarette smoke. B[a]P- induced tumors in the hamster cheek pouch are primarily endophytic squamous cell carcinomas that closely resemble squamous cell carcinomas of the human oral mucosa. The cheek pouch of male Syrian hamsters were treated topically for eight weeks with 0.6% curcumin, 6.0% curcumin, 2.5% green tea polyphenols, or 5.0% green tea polyphenols, 3 times per week 30 minutes prior to the application of 2.0% B[a]P. The animals were sacrificed 24 hours and 72 hours after the last treatments. Short-term mechanistic markers of malignant progression were used to determine effects of each compound. Cellular proliferation, assessed by bromodeoxyuridine (Brdu) incorporation, p53 protein accumulation, and apoptotic activity were evaluated. The results of the present study demonstrated that 0.6% curcumin and 2.5% green tea polyphenols had strong inhibitory effects on cellular proliferation and p53 protein accumulation. And 6.0% curcumin and 5.0% green tea polyphenols appeared to induce apoptosis. Our data suggest that curcumin and green tea polyphenols may have a plausible chemopreventive effect on oral carcinogenesis in the hamster cheek pouch model.
