will suggest itself to you that such a comprehensive subject as Indian fevers could be touched on only in the slightest and most superficial manner, in the brief space accorded me. Instead, therefore, of endeavouring to wander discursively through the wide domain of Indian fevers generally, I shall attempt to limit my remarks to some few, select, points in the history of what is par excellence ...

This paper has a marked practical aspect. We wish to encourage and facilitate the use of Q methodology amongst psychologists interested in qualitative research. The paper duly answers a number of pertinent ‘how to do Q’ questions. Yet our primary intention is not to produce an exhaustive ‘how to do Q’ guide. In discussing issues of theory, method and interpretation in Q methodology, the main ai...

in this paper we have generalized the concepts of ,q-fuzzy ideals, ,q-fuzzy quasi-ideals and,q-fuzzy bi-ideals by introducing the concepts of   k ,q -fuzzy ideals,   k ,q -fuzzy quasiideals and   k ,q -fuzzy bi-ideals in ternary semigroups and several related properties are investigated. different characterizations of regular and weakly regular ternary semigroups b...

امروزه مبدلهای کلیدزنی چند سطحی در کاربردهای بسیاری مانند درایوهای ac، منابع تغذیه ac و جبرانسازهای توان راکتیو بکار گرفته می شوند.ولتاژ خروجی در این مبدلها از ترکیب چندین سطح ولتاژ که عموماً از منابع خازنی به دست می آیند، ساخته می شود. روش کلیدزنی در این مبدلها مانند مبدلهای دو سطحی متنوع بوده و با معیارهایی از قبیل میزان استفاده از ولتاژ باس dc طیف هارمونیکی ولتاژ خروجی منتجه و عملکرد دینامیکی...

The tracing methods determine the contribution the power system sources have in their supplying. The methods can be used to assess the transmission prices, but also to recover the transmission fixed cost. In this paper is presented the influence of the modification of commons structure has on the specific price of transfer. The operator must make use of a few basic principles about allocation. ...

This study explores mobile users’ perceptions about SMS advertising. The empirical study uses a double methodology. First, a qualitative study using the Q-method is conducted. Qualitative analysis reveals that negative attitudes are commonly shared, and that ad-clutter is perceived critically. Therefore, in a second step, a quantitative study is adopted to assess the impact of attitudes towards...

In [2, 3] we gave a number of formulas for qKdV equations derived in a q-Virasoro context. The constructions were meaningful even though the cocycle terms did not visibly satisfy a Jacobi identity. In the present note we modify the framework slightly and produce a cocycle term (morally equivalent to one of those used in [2, 3]) and thereby exhibit a more convincing candidate for a canonical qKd...

Ecotourism spatial planning requires the balance of both development and conservation. Through environmental data analysis, many researchers have suggested spatial planning that falls between these two polarizing concepts. Nonetheless, ecotourism development has been criticized as inconsiderate of places that are precious to local residents. The purpose of this study is to map local stakeholder...
