Determination Of Palm Biodiesel/Petroleum Diesel Blend Ratio Through Spectroscopic Method / Alinda Samsuri, Alinda Samsuri

Student Works (2000-2009)

Biodiesel, defined as the alkyl esters (usually methyl esters) of vegetable oils, is miscible with conventional petroleum diesel fuel at all blend levels. Blends of biodiesel with conventional petroleum diesel fuel represent a common utilization of biodiesel. The Malaysian Government has initiated the implementation of palm biodiesel since 2007 and the proposed blend is B5. Accordingly, there is interest and need for the development of methods for determining or verifying the blend level of biodiesel in petroleum diesel. To date, the most widely used and acceptable method for determination of biodiesel blend levels is using IR spectroscopy. The present study …

Bioremediation Of Landfill Gas Under Laboratory Conditions / Navarani A/P Vejaratnam, Navarani Vejaratnam

Student Works (2000-2009)

Per capita generation of municipal solid waste (MSW) in Malaysia has reached 1.3kg per day giving a total generation of more than 31000 tonnes daily. All the MSW collected are disposed into 260 landfills or dumps with 90% of the landfills being non-sanitary. Due to lack of proper gas collection facilities, almost all the methane produced are released passively to the atmosphere.Malaysian landfills produce 1.3-7.5 L/kg/year of methane gas. Since methane is 23 times more harmful as greenhouse gas than CO2, it is essential to mitigate its emission from landfills. One option to reduce methane emissions is to oxidize the …

An Investigation Into Hotel Employees' Perception Of Green Practices, Sun-Hwa Kim

Electronic Theses and Dissertations

This study examined how employees of the hotel industry perceived green practices. Data was collected from 220 employees working in eight green certified hotels in Orlando. Research results revealed that performance levels of green practices implemented by hotels were lower than the importance levels of those same green practices as perceived by hotel employees. The results of the study illustrated that (1) the employees' perception regarding green practices was not different than one of hoteliers in terms of importance and performance, and (2) employees weighted the green practices that were beneficial to them as more important than green practices that …

Delayed Rejection Of Mhc Class Ii-Disparate Skin Allografts In Mice Treated With Farnesyltransferase Inhibitors, Ken Field

Faculty Journal Articles

Farnesyltransferase inhibitors (FTIs), developed as anti-cancer drugs, have the potential to modulate immune responses without causing nonspecific immune suppression. We have investigated the possibility that FTIs, by affecting T cell cytokine secretion, can attenuate alloreactive immune responses. The effects of FTIs on murine alloreactive T cells were determined both in vitro, by measuring cytokine secretion or cell proliferation in mixed lymphocyte cultures, and in vivo, by performing skin allografts from H-2^bm12mice to MHC class II-disparate B6 mice. We found that two different FTIs, ABT-100 and L-744,832, blocked secretion of IFN-γ, IL-2, IL-4, and TNF-α from naïve …

Roses Are Red, Violets Are Bluehow Poetry In Science Can Help Students Learn Something New, Kimberly Casselman

Electronic Theses and Dissertations

This study was an attempt to examine how poetry integrated with science could assist eighth graders in the memorization of key science vocabulary words. Furthermore, it would investigate if student attitude, interest, and motivation would improve with the use of the poetry. Instruction was adjusted to implement poetry into astronomy lessons. Memorization activities such as poems, chanting, and repetition were used to help students remember the vocabulary and the definitions. Pre/post tests were used to interpret if the poetry did assist in the memorization of the astronomy vocabulary. Science interest surveys and science attitude surveys were used to interpret if …

Changes In Longitudinally Assessed Biomechanical Parameters Related To Increased Risk Of Anterior Cruciate Ligament (Acl) Injuries In Adolescent Female And Male Athletes, Kevin Ray Ford

University of Kentucky Doctoral Dissertations

Females suffer anterior cruciate ligament (ACL) injuries at a 2 to 10-fold greater rate compared to male athletes participating in similar sports. Altered movement patterns and inadequate knee stiffness are two interrelated factors that may increase ACL injury risk. Onset of these neuromuscular risk factors may coincide with the rapid adolescent growth that results in the divergence of a multitude of neuromuscular parameters between sexes. The overall purpose of this dissertation was to determine if neuromuscular ACL injury risk factors in female athletes increase following rapid growth and development compared to males. Male and female athletes were tested with three-dimensional …

Regulation Of Low Density Lipoprotein Receptor Splicing Efficiency, I-Fang Ling

University of Kentucky Doctoral Dissertations

Low density lipoprotein receptor (LDLR) is an apolipoprotein E (apoE) receptor and may play a role in Alzheimer’s disease (AD) development. A single nucleotide polymorphism (SNP), rs688, that has been identified to modulate the splicing efficiency of LDLR exon 12 and is associated with higher cholesterol and AD in some case-control populations. The exon 12 deleted mRNA is predicted to produce a soluble form of LDLR that fails to mediate apoE uptake. To gain additional insights, in this study, I seek to understand the regulation of LDLR splicing efficiency. To identify functional cis-elements within LDLR exon 12, I mutated several …

Direct Products And The Intersection Map Of Certain Classes Of Finite Groups, Julia Chifman

University of Kentucky Doctoral Dissertations

The main goal of this work is to examine classes of finite groups in which normality, permutability and Sylow-permutability are transitive relations. These classes of groups are called T , PT and PST , respectively. The main focus is on direct products of T , PT and PST groups and the behavior of a collection of cyclic normal, permutable and Sylow-permutable subgroups under the intersection map. In general, a direct product of finitely many groups from one of these classes does not belong to the same class, unless the orders of the direct factors are relatively prime. Examples suggest that …

Age May Be Hazardous To Outcome Following Traumatic Brain Injury: The Mitochondrial Connection, Lesley Knight Gilmer

University of Kentucky Doctoral Dissertations

Older individuals sustaining traumatic brain injury (TBI) experience a much higher incidence of morbidity and mortality. This age-related exacerbated response to neurological insult has been demonstrated experimentally in aged animals, which can serve as a model to combat this devastating clinical problem. The reasons for this worse initial response are unknown but may be related to age-related changes in mitochondrial respiration.

Evidence is shown that mitochondrial dysfunction occurs early following traumatic brain injury (TBI), persists long after the initial insult, and is severitydependent. Synaptic and extrasynaptic mitochondrial fractions display distinct respiration capacities, stressing the importance to analyze these fractions separately. …
