در سراسر این پایان نامه r را یک حلقه نوتری جابجایی و یکدار و m را یک مدول با تولید متناهی روی r در نظر گرفته شده است. این پایان امه در سه فصل نوشته شده که در فصل اول تمامی تعاریف قضایایی را که لازم خواهند بود آورده شده است. فصل دوم و سوم براساس دو مقاله زیر تهیه شده است.فصل دو براساس مقاله زیر:injective modules and linear growth of primary decompositions که توسط r.y.sharp در...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
air pollution is one of the major issues is the use of fossil fuels. air pollution in different ways harmful effects of long-term, short-term, devastating and sometimes irreversible in humans, animals and plants life. air pollution leads to increased heart disease, breathing, decreased vision, warming, acidification, etc. one of the problems of air pollution. air pollution threatens the surviva...
This study intends to provide an empirical answer to the question of whether Maastricht and SGP fiscal rules have affected growth of European Union countries. A growth equation augmented with fiscal variables and controlling for the period in which fiscal rules were implemented in Europe is estimated over a panel of 15 EU countries (and 8 OECD countries) for the period 1970-2005 with the purpos...
abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
The estimation of a linear equation from panel data with measurement errors is considered. The equation is estimated (I) by methods operating on the equation in differenced period means, and (II) by Generalized Method of Moments (GMM) procedures using (a) the equation in differences with instruments in levels and (b) the equation in levels with instruments in differences. Both difference transf...
Physicians are key personnel in a sector which is important due to its size as well as the quality of service it provides. We estimate the labor supply of physicians employed at hospitals in Norway, using personnel register data merged with other public records. A dynamic labor supply equation is estimated using a sample of 1303 male physicians observed over the period 1993-1997. The methods of...
In this paper we derive a test statistic generating equation (TSGE) from which several statistics suitable for testing parametric restrictions in models estimated by the generalized method of moments (GMM) may be obtained. This statistic presents three main features: it is valid for producing statistics appropriate for testing constraints expressed in very general forms, which may involve not o...
