The aim of this study was to increase the understanding of diversity and activity of dominant bacterial populations in the rhizospheres of three economically important grain legumes (Vicia faba, Lupinus albus and Pisum sativum). A cultivation-independent approach was employed to achieve this aim bearing in mind the limitation of cultivation-dependent technique that only 10% of bacteria present in rhizosphere can be cultured. PCR amplification of 16S rDNA and subsequent separation of the amplicon...

This thesis studies the optical burst switched (OBS) networks. It consists of three parts.In the first part, we present a detailed analysis of three major wavelengthreservation schemes for OBS networks: JIT, JET, and Horizon.The contributions include:(i) analytical models of JET and Horizon (on a single OBSnode) that are more accurate than previously published ones and valid for general burst length and offset length distributions;(ii) determination of the regions of parameter values, such as bu...

Sociology

AbstractTaylor, Tiffany. Defining Anger: Deconstructing the Experience and Expression of Angerby Race, Class, and Gender. (Under the direction of Barbara Risman.)The research on anger in the sociology of emotions literature, however, categorizes anger as a negative emotion, a form of distress with negative consequences. In contrast, I see anger as a potential source of empowerment and expect it to be tied to attributes of stratification, to gender, race, and class. Unlike much of the prior resea...

Computer Science

Long-running parallel applications suffer from performance limitations particularly due to inefficiencies in accessing memory. Dynamic optimizations, i.e., optimizations performed at execution time, provide opportunities not available at compile or link time to improve performance and remove bottlenecks for the current execution. In particular, they enable one to apply transformations to tune theperformance for a particular execution instance. This can potentially include effects of the environm...

Crop Science

In all agricultural systems using few or no herbicides, cultural and mechanical techniques are crucial to economic viability. Further advances in non-chemical weed control will require in-depth knowledge of weed biology. The objective of new strategies likely will be to alter competitive interactions between crop and weed species. An important part of weed biology, and often the basis for competitiveness, is species response to the environment. Environmental conditions differ greatly in differen...

Computer Science

Direct manipulation interfaces already employ a weak analogy to the use of physical tools in the real world. Despite certain tradeoffs, a stronger application of tool-using principles can lead to improvements in the design of software interfaces. I outline here some of the theory behind such an approach, and describe the design of systems that follow these principles, with emphasis on a tool-based drawing application called HabilisDraw.

Sociology

Using data from the 1998 General Social Survey, this thesis examines the effects of black-white contact and close interracial friendships on whites attitudes towards blacks. Intergroup contact theory maintains that contact between people of different groups reduces prejudices and improves attitudes. The majority of previous contact studies have focused on casual black-white contact in neighborhoods and workplaces. Emerging in the current literature is a focus on more personal contact between bla...

Civil Engineering

Methyl tertiary-butyl ether (MTBE) is frequently detected in surface and ground water. Because of its hydrophilicity, MTBE is difficult to remove from aqueous solution by activated carbon adsorption processes. In drinking water treatment applications, natural organic matter (NOM) also adsorbs on activated carbons, which further decreases the MTBE adsorption capacity. Unlike activated carbons, high-silica zeolites are adsorbents with well-defined pore sizes. From a drinking water treatment perspe...

In this paper, let be a sequence of k-record values from a population with common distribution function F. We will characterize the continuous (or discrete) distribution function F by the conditional expectation functions. We also study the necessary and sufficient conditions such that the conditional expectations of k-record values hold for some distribution function F. A corresponding characterization based on weak k-record values and some related characterizations are also investigated.

AbstractSmall and medium enterprises (SMEs) were one of the major contributors to the economic miracle of Taiwan. There are over a million SMEs, which comprise 97.7% of all Taiwanese enterprises, However, SMEs faced with high risks of failure, especially at their entrepreneurship stages, due to their lack of expertise and abilities in technologies developments, together with their disadvantages in economy scale, market, capital and business connections. Thus more than 60 incubators were founded ...
