Recent efforts show that microchannel technologies have much to offer the field of nanomanufacturing: the structuring of matter on the order of one billionth of a meter. During the synthesis of nanomaterials, microchannel reactors take advantage of large surface-to-volume ratios to accelerate heat and mass transport. This accelerated transport allows...

The fermentation of honey-based musts has been a feature of civilization for millennia. Typically comprised of 75-90% (w/w) simple (i.e. fermentable) sugars, the glucose and fructose present are readily fermented by either pitched or adventitious micro-organisms. Nevertheless, despite its venerable heritage, honey-based fermentations are prone to inconsistency, and it is...
Many D2d-symmetric 2,2',6,6'-tetrasubstituted biphenyls are
readily prepared via net oxidative dimerization of appropriate
1,3-disubstituted benzenes. Conversion of such proprochiral
compounds to useful C2-symmetric chiral biphenyls requires
formal replacement of two substituents on opposing aryl ring
units with alternate groups. This under exploited
desymmetrization tactic has been demonstrated for the
generation...
Quinolinate (QUIN) is an endogenous neurotoxic product of the kynurenine
pathway of tryptophan metabolism. Quinolinate is a selective agonist of the NMDA
family of glutamate receptors and, as such, may play a role in the pathology of a number
of major central nervous system (CNS) disorders. These include both chronic...
Advances of colloidal nanomaterials for societal benefit have been hampered by the high cost and low quality of nanoparticles (NPs). The production of high quality nanoparticles within colloidal suspension has two related concerns; (1) current high production rates methods of synthesizing nanoparticles result in a larger range of particle size,...
In 2011 Oregon enacted a public education open enrollment policy that gives students and families the choice of what school to attend, regardless of district lines. Despite the lack of public information, this policy will sunset this school year unless it is further extended during legislative session. This paper attempts...
The FLEX/REFLEX paradigm is applied to the description of a computer program system. The paradigm is shown to be relevant and appropriate to computer program systems and to advantageously display and structure the general hierarchical characteristics of computer program systems. Program systems characterized in the paradigm are described both holistically...
Chromosome maps were made of Drosophila gibberosa salivary gland
and fat body chromosomes, and the puffing patterns were compared in
the two tissues for selected times in development. The times were
early third instar (E), late third instar (0, at pupariation
(0 hr), at two hours (2 hr), four hours...
Most measures of program complexity gauge either textual or
control flow attributes of a program. A recent addition to the field
of complexity measures, the knot metric, is a function of both these
attributes. A knot measurement reflects the degree of control-flow
tangle in a program's listing. This thesis discusses...
The purpose of this study was to evaluate a native remnant forest in Westport, Connecticut. The study site is a fragmented woodland located near a highly urbanized area of roadways and development. Preliminary descriptive information was collected for a partial sampling of tree stands in an attempt to obtain baseline...
In this work, continuous synthesis routes for binary nanoparticles using advantages of microchannel mixing (low diffusion distances and higher mass transfer) and fast heating rates provided by ultrasound induced heating are investigated. In addition, the application of silica nanoparticles in anti-reflective coatings on glass and understanding the structure property-performance correlation...
The arithmetic portions of almost all modern processor architectures are of very similar design. We use the term "traditional" to describe this design, the primary characteristics of which are native support for integer and floating-point number types and special disjoint instructions and hardware for each supported type. Decades of refinement...
As urban populations increase, the presence of well-maintained trees provide a cost-effective solution to combat the effects of climate change, specifically the urban heat island effect. Unfortunately, the associated ecological, social and economic benefits of trees are not distributed equitably in the landscape due to lingering effects of redlining policies....
The behavior of a metal vapor plasma arc in a vacuum arc remelting (VAR) furnace is believed to contribute to the formation of defects in reactive metal and super-alloy ingots. Industry standard instrumentation, which includes electric current and voltage measurements, can asses the stability of an arc but cannot predict...
In this work we propose a computer based approach by means of
which the decision maker in Bendel State, Nigeria, can best be assisted
in the formulation of policies related to land use.
In Chapter I we briefly discuss the role of the computer in
planning and state the problem....
Soil bulk density and disturbance were measured before and after a commercial
thinning of 3 0-50 year-old Douglas-fir using a cut-to-length (CTL) and a skyline system
on the Willamette National Forest in the Oregon Cascades. A dual-probe nuclear
densimeter was used to measure bulk density at four and eight inches....
Reinterpretation of the leafhopper tribe Scaphytopiini reveals it
to be primarily a New World taxon with only limited representation in
the Palearctic, Oriental and possibly Ethiopian regions. Approximately
75 species assigned to three genera are known from the United
States and Canada with at least another 75 species representing an...
Effective management of urban forests is vital to society due to the numerous ecological, economic, and social benefits they provide. In many cities, management efforts are commonly supported by citizen advisory groups, which are often generically referred to as “tree boards” within the urban forestry context. Very little is known...
Greenway trails have become a popular way to connect communities, increase public health and provide ecosystem services. Urban forests provide similar and overlapping benefits as greenways but are often unknown and underfunded. Integrating urban forest management with greenway management could be a way to create synergistic benefits for the community....
