This report deals with forestry in Korea in its various aspects and what has been done about forestry problems in Korea.
The ratio of forest land to total area of country is so high
that it is sometimes compared to Finland's, but the similarity with Finland stops there.
The adverse...
The evolutionary relationship between Frankia and actinorhizal plants was evaluated
by reconstructing molecular phylogenetic trees from nifH, 16S rDNA, and rbcL
nucleotide sequences. Subgroupings in Frankia phylogenetic trees reconstructed from
nifH and from 16S rDNA sequences were consistent in terms of plant origins of Frankia
strains. Although the branching order...
Microbial electrolysis cells (MECs) for hydrogen production exhibit great advantages over many other biohydrogen production techniques in terms of versatility of substrate and hydrogen yield. However, hydrogen scavenging by methanogens put forward a great challenge to the application of the single chamber MECs when using mixed culture. Various strategies were...
Deep learning is now being utilized widely in applications where sensitive data is being used for model training, for example, in health care. In this scenario, any data leakage will cause privacy concerns to whose data records are used to train the model. An attacker can actively cause privacy leakage...
This thesis argues for significant correlations in the politics of representation of Chinatown and mother-daughter relationships in two literary texts by Maxine Hong Kingston and Fae Myenne Ng. The two novels do not follow traditional representations of Chinatown and provide critical representations of Chinatown and mother-daughter relationships. First, Kingston's The...
We explore the application of deep learning to the disparate fields of natural language processing and computational biology. Both the sentences uttered by humans as well as the RNA and protein sequences found within the cells of their bodies can be considered formal languages in computer science, as sets of...
The reactions of cyclodeca-1, 2, 5, 8-tetraene with mercuric salts
in solvents of varying nucleophilicity are described. Instead of forming
the usual oxymercuration products reported for reactions of olefins
and allenes with mercuric salts, the major products obtained in the
present cases result from the initial electrophilic addition of the...
This thesis consists of three manuscripts related to the methodology of evaluating charring behavior in cross laminated lumber panel specimens subjected to fire performance tests on cross-laminated lumber panel specimens. The topic of the first manuscript is the measurement of char rates of unprotected CLT layups fabricated with ponderosa pine...
In this dissertation, I present the work of developing more efficient and economical techniques for fragmenting large bio-molecules, and ultimately making mass spectrometry a more powerful tool in proteomics, DNA sequencing, and other areas of biomolecular analysis.
Aiming at lowering the installation and operating cost, and delivering electron capture dissociation...
Piezoelectric materials have been widely used in electromechanical actuators, sensors, and ultrasonic transducers. Among these materials, lead zirconate titanate Pb(Zr[subscript 1‐x]Ti[subscript x])O₃ (PZT) has been primarily investigated due to its excellent piezoelectric properties. However, environmental concerns due to the toxicity of PbO have led to investigations into alternative materials systems....
The demand for the development of sustainable energy is an all time high as we burn through limited fossil fuel reserves and as environmental concerns rise every year. Renewable energy sources such as wind and solar power have limitations due to inconsistent power supply that cannot meet the regular needs...
The rural two-lane highway in the southeastern United States is frequently associated with a disproportionate number of serious and fatal crashes. The major research objectives are to investigate the relations between probabilities of fatal crash type occurrence and potential contributing factors from road geometric design characteristics and roadside, environmental features....
The flux-gradient relationship of water vapor Fq was obtained from the Cooperative Atmosphere-Surface Exchange Study-1999 (CASES-99) field experiment, which was conducted on a flat and grassy field in the southeastern part of Kansas, USA, during October 1999. The CASES-99 data include turbulence measurements of wind, temperature, and vapor density along...
Compositional data is a type of data where the features are non-negative and always sum to a constant. This type of data is frequently encountered in many fields such as microbiology, geology, economics and natural language processing. Compositional data has unique statistical properties that makes it difficult to apply standard...
This objective of this study is to investigate the capability of nanostructured surfaces on dissipating heat flux by performing pool boiling and convective flow boiling. The generation of ultra-high heat flux from high performance electric devices has motivated a number of investigations related to advanced heat transfer especially in two-phase...
Biocompatible hydrogels composed of covalently crosslinked, chemically modified hyaluronan (HA), gelatin (Gtn), and heparin (Hp) were synthesized for controlled release of human vascular endothelial growth factor (VEGF) or basic fibroblast growth factor (bFGF). We hypothesized that inclusion of small quantities of heparin in these gels would result in regulated growth...
Nitrosomonas europaea (ATCC19718) participates in the biological removal of nitrogen from wastewater by oxidizing ammonia to nitrite, the first step in nitrification. This bacterium is sensitive to heavy metals (Zn²⁺, Cd²⁺, Cu²⁺, and Hg²⁺) and cyanide, compounds commonly encountered in wastewater treatment plants. Therefore, we characterized physiological and transcriptional responses...
The production of Cheddar cheese is a complex process with multiple potential sources of undesirable bacteria, including those that have negative impacts on product quality (spoilage organisms) and those that are used to evaluate sanitary conditions in the production environment (indicator organisms). The dairy industry commonly uses coliform bacteria as...
