description: The subjects of this study are two proteins called c-Fos and c-Jun, which have important roles in the development of lung cancer induced by cigarette smoke. When the airway lining is exposed to toxicants in the cigarette smoke, c-Fos and c-Jun are activated in certain cells. c-Fos and c-Jun function as a pair by forming a plier-like structure that clamps down on DNA and turns on particular genes. Activation of these genes can lead a cell down the path toward cancer. Many studies suggest that c-Fos and c-Jun induce lung cancer, while others suggest they may suppress it. The reasons why they can act in both ways are not yet clear, and understanding why will be important for controlling their functions. We have hypothesized that the dual nature of c-Fos and c-Jun is due to certain chemical modifications that alter their properties. The goal of our studies is to determine whether a type of small sugar is linked to them, and, if so, how this sugar affects their functions in lung cancer.

 Chemical modifications change protein functions by adding small tags to them so they will be recognized differently by other molecules in the cell. The tagging process is reversible and its effect can be further controlled by another tag. It is analogous to painting a taxi yellow so people will wave at it, but putting on the “off-duty” light will prompt them to wait for the next cab. The cell uses these tags to quickly generate multiple functions out of the same protein. A type of tag called phosphate at certain positions of c-Fos and c-Jun appears to be necessary for their ability to induce cancers. However, c-Fos and c-Jun tagged at these same positions are also reported to suppress tumors. These perplexing findings suggest to us there may be additional unidentified tags that also control their activities. In fact, preliminary studies in our laboratory have identified a new tag on c-Fos and c-Jun, called O-linked N-acetylglucosamine, which is a small sugar molecule. This sugar tag generally modulates the function of a protein in a manner opposite to the phosphate tag. Since phosphate tags appear to be necessary for the cancer-inducing effects of c-Fos and c-Jun, we will investigate if the sugar tag has tumor-suppressive effects in lung cancer cells. The proposed research will provide insights into the mechanism that cigarette smoke induces lung cancer, as well as new drug targets for lung cancer therapy.

description: In the United States, one quarter of mothers who smoke continue to do so during pregnancy (or gestation). Numerous scientific studies have reported that gestational nicotine exposure can lead to shortfalls in learning (to acquire information) and memory (to retain and recall information), in children of mothers who smoked during pregnancy. Unfortunately, little information is currently available as to the reasons why this relationship exists, although human and animal studies are starting to provide more evidence that this link is due to the harmful effects of nicotine (the addictive drug in cigarettes) on the growing brain. Therefore, my proposal aims to determine the cause of gestational nicotine induced learning and memory impairments.

 In the rat, nicotine can directly interact with certain types of cells (noradrenergic neurons) in the brain to release the compound, norepinephrine. This compound has been shown to be important in numerous brain functions (i.e. attention, arousal, stress, and learning and memory). The research in our lab has already shown that the children of rat mothers (offspring of dams), who were exposed to nicotine during pregnancy, release more norepinephrine than those that were not exposed. Moreover, this change in norepinephrine release in the nicotine exposed offspring can remain until adulthood. This result suggests that brain functions, dependent on the amount of norepinephrine around in the brain (i.e. attention, arousal, stress, and learning and memory), may be altered in the animal until adulthood, a finding that has been shown in human studies. In this proposal, the focus has been placed on learning and memory changes, allowing us to hypothesize that nicotine exposure during animal development can have harmful effects on the brain, altering the amount of norepinephrine around, thereby causing problems in an animals’ ability to learn and remember.

 I am proposing to perform two behavioral experiments (an emotional memory task and a “smell” memory task) that have been shown to require a precise amount of norepinephrine for accurate animal performance. The aim is to (i) see whether a single exposure of nicotine can affect either one of the memory tasks, and (ii) determine whether continuous nicotine exposure during a dams’ pregnancy will affect the memory of the developing offspring.

 If the hypothesis is correct, researchers can use this information to further understand the cause of learning and memory deficits seen in the children of mothers who smoke. Furthermore, the results can be used to educate the public, in more detail, about the harmful effects of smoking during pregnancy. Finally, the findings can also help scientists develop drugs that could prevent learning and memory problems that occur because of maternal cigarette smoking.
Multidimensional modelling of Cross-Beam Energy Transfer for direct-drive Inertial Confinement Fusion
Creators: name: Moloney, Philip
Publisher: name: Imperial College London
Year: 2024

description: Accurate modelling of laser propagation and energy deposition in direct-drive Inertial Confinement Fusion (ICF) is crucial to performing predictive simulations. Cross-Beam Energy Transfer (CBET) is an interaction of laser light and the plasma state of matter, which can halve the deposited power in direct-drive implosions and amplify deposition asymmetries by an order of magnitude. Computational models which do not account for CBET, can therefore not be truly predictive. This thesis presents the development, validation and use of SOLAS: a 3-D, ray-based CBET model, which has been integrated into the CHIMERA code. The development of SOLAS and its integration into the CHIMERA code are described. Test problems were conducted which validated the ray-trace, energy deposition, electric field reconstruction and CBET solver. CHIMERA-SOLAS simulations of direct-drive targets on the OMEGA laser facility are presented, which are in excellent agreement with existing codes. A study is presented, which investigated the role of CBET with respect to the beam radius initial condition for direct-drive implosions. The results demonstrate that in the absence of CBET, increasing the beam radius improves the stagnation state symmetry of implosions. However, a larger beam radius leads to more CBET and a subsequent symmetry degradation. These results could help to explain observed trends in statistical modelling of OMEGA implosions. A final study is presented, which aimed to understand how the role of CBET changes when a target is magnetised prior to the laser drive. Magnetised direct-drive experiments have demonstrated that anisotropic thermal conduction in the coronal plasma can lead to asymmetry of the implosion. Simulations of magnetised direct-drive targets were conducted, to understand if coronal magnetisation affected CBET scattering. Although CBET was observed to be dynamically significant to the implosions, the interplay of CBET with the magnetic field was found to be minimal.

description: Despite all the triumphs of modern medicine, lung cancer remains a terminal illness. The statistics are staggering: 85% of the people with lung cancer will die within 5 years of being diagnosed. With the highest fatality rate among the various cancer subtypes, accounting for nearly one-third of all cancer-related deaths, this disease claimed more than 150,000 lives over the past year in the United States alone. Not surprisingly, the great majority of lung cancer cases are attributed to smoking cigarettes. In the search for an ultimate cure, the development of new treatment options to prolong human life are of far-reaching consequence.

 In the 1970’s, scientists at Sandoz Ltd. discovered the drug Etoposide, which today provides the first line of defense for people who suffer from lung cancer. Unfortunately, previous attempts at making Etoposide have generally proceeded through long, inefficient processes, so lung cancer patients must currently rely upon plant extracts to provide them with this important remedy. These restrictions have also prevented scientists from making many compounds related to Etoposide, which could have promising anticancer properties.

 Therefore, this project proposes a new, highly efficient way to make Etoposide. The knowledge gained by this research has the potential to provide a cost-effective, and rapid way to obtain this valuable clinical therapeutic. Perhaps even more importantly, this approach allows for a great deal of flexibility so that compounds that are related to Etoposide that have never been previously made can be developed. These compounds could lead to the discovery of new, more effective, lung cancer treatments and would represent contributions to both organic chemistry as well as the treatment of tobacco-related diseases.

Change and discontinuity within the Severan dynasty: the case of Macrinus
Creators: name: Scott, Andrew G.
Publisher: name: No Publisher Supplied
Year: 2008

description: This dissertation examines the figure of Macrinus and his relationship to the Severan dynasty and the third century.  As a usurper and non-aristocratic eques, Macrinus presents a problem of continuity within the Severan dynasty and in many ways was the precursor to the so-called "Third Century Crisis" of 235-285.The opening chapters of this dissertation examine the state of Caracalla's foreign and domestic policy at the end of his reign (primarily 215-217), Caracalla's assassination, and Macrinus' accession.  There is also a discussion of Macrinus' career prior to his accession and his initial consolidation of power.A central question is how Macrinus legitimized his reign.  The evidence, which includes literary, epigraphic, and numismatic sources, shows that he planned a familial succession that would be passed down to his son Diadumenian.  Determining how Macrinus expressed his relationship both with the Severans and with his own son is critical for understanding how he tried to situate himself, as usurper, within the ruling family.A further area of importance is Macrinus' program.  Though detractors have suggested that the brevity of Macrinus' reign made it impossible to have a coherent program, even in a short reign development can be traced.  Macrinus was left with a variety of problems due to the failed policies of Caracalla, and it will be the purpose of this study to assess how he attempted to correct these missteps and how he developed his own policies.Finally, Macrinus was a victim of the struggle for power among the army, the equestrian bureaucracy, and the imperial family.  An aspect of the illegitimate nature of Macrinus' reign was the almost instantaneous competition from the Syrian half of the house of Severus, orchestrated by the female relatives of Julia Domna.  An investigation into the characters surrounding this power struggle, with particular emphasis on the women of the Severan line, will illuminate the inner workings of imperial families in this period and the power that women could wield.

description: Well intervention pressure control refers to the processes and equipment used to safely manage and control wellbore pressure during various types of interventions in oil and gas wells. These interventions may involve maintenance, repairs, or enhancements to a well to restore or improve its productivity, without completely drilling a new well. The key aspect of pressure control is to prevent uncontrolled flow of fluids (oil, gas, or other wellbore fluids) that could lead to blowouts or hazardous situations. Key components of well intervention pressure control include: 1. **Blowout Preventers (BOPs):** These are critical safety devices designed to seal, control, and monitor oil and gas wells to prevent blowouts. For well intervention, there are specific types of BOPs like annular and ram-type preventers. 2. **Coiled Tubing Units (CTU):** In some interventions, coiled tubing is used to perform operations inside the well without needing to remove the tubing string. Pressure control equipment like injector heads and stripper BOPs are used to maintain well integrity during these operations. 3. **Wireline Pressure Control Equipment:** Wireline interventions, where tools or equipment are lowered into the well on a wire, require specialized pressure control tools such as lubricators, grease injection systems, and wireline BOPs to maintain well control while allowing for intervention operations. 4. **Snubbing Units:** This equipment is used to force pipes into wells that are under pressure. Snubbing allows for operations without shutting down the well completely, making pressure control a vital safety aspect of the process. 5. **Wellhead and Christmas Tree:** These are the assemblies at the surface of the well that control pressure and regulate production. During interventions, modifications or special pressure control equipment are attached to these assemblies to ensure safety. 6. **Kill Fluid:** In some situations, heavy fluids known as kill fluids are pumped into the well to counteract the pressure from subsurface formations, helping to control the well during intervention. Well intervention operations can be high-risk, and effective pressure control is essential to avoid uncontrolled releases of hydrocarbons, safeguard personnel, and protect the environment.

Does graduation from a token economy predict long-term outcomes of a residential treatment program?
Creators: name: Schwab, Avi-Yonah M.
Publisher: name: No Publisher Supplied
Year: 2008

description: Token economies are efficacious and widely-used treatments for disruptive adolescents in residential settings.  However, the literature suggests that positive effects of these treatments may not maintain or generalize when artificial reinforcement is no longer available.  Theory and research from both social and behavioral psychology suggest that generalization could be enhanced if acute behavior change in token economies is followed by a phase that emphasizes self-regulation training and natural and logical consequences over token reinforcement.  At Girls and Boys Town's family-style residential program for youth with multiple behavioral and environmental problems, youth who succeed in the program progress through motivation system levels, from traditional token economy levels to a motivation system that emphasizes self-regulation and natural and logical consequences.  It was hypothesized that youth who ended their treatment at higher motivation system levels would have better outcomes at 5-16-year follow-up, even when controlling for a proxy of general success in the treatment program (Favorable Departure Rating).  One cohort of former residents was surveyed 16 years, on average, after departure (n = 207; 42% of the total cohort), and another cohort of former residents was surveyed 5 years after departure (n = 131; 61% of the total cohort).  Data on respondents were also collected from treatment records.  Analyses of the 16-year follow-up group suggested that discharge from higher motivation systems positively predicted educational attainment, household income, and military service and marginally predicted locus of control and happiness.  However, when controlling for Favorable Departure, motivation system marginally predicted only two outcomes.  Favorable Departure was a more reliable predictor of happiness, highest grade completed, and (marginally) respondents' retroactive evaluation of the treatment at follow-up than motivation system was.  Neither measure significantly predicted outcome on 13 other long-term outcome measures.  In the 5-year follow-up group, motivation system was again a strong predictor of military service, even when controlling for Favorable Departure.  However, neither motivation system nor Favorable Departure was a significant predictor of any of the other 16 long-term outcome measures.  Exploratory analyses of predictors of post-treatment success and long-term follow-up outcomes of residential treatment were also conducted.  Extensive recommendations for follow-up research are offered.

A robotic welding system can offer companies a competitive advantage over those that have not made the shift to welding automation. There are several steps manufacturers can take — from choosing the right system to proper weld cell design and operator training — to optimize results and help ensure maximum ROI from the investment. In this guide to welding automation, learn more about: Benefits of robotic welding Types of welding robots Choosing a robotic gun and nozzle Robotic weld cell design Operator training Best practices for welding automation Benefits of robotic welding Automated welding is especially well-suited for operations that produce highly repeatable parts and have low variability in what they are making. The change can help companies increase productivity, more aggressively and accurately bid work, and identify inefficiencies elsewhere in the manufacturing process.
Probing the structure of dextran systems and their organization

Year: 2008

description: Dextran with molecular weight 9,700 (T10) was dissolved directly in water (66%) at room temperature to form a concentration of three times its overlap concentration. Wide angle x-ray scattering (WAXS) and differential scanning calorimetry were used to monitor the change in the crystallinity of concentrated dextran solutions with time. Dextran solutions (66%) were also probed with steady and dynamic rheological measurements to understand the changes in structure as the concentrated dispersion aged, Finally FTIR was used to understand the molecular origins of the crystalline changes of the concentrated dextran solution. Concentrated dextran solutions showed a phase transition from clear solution to opaque semi-solid without water losses a result of aging time. Both WAXS and DSC measurements indicated that the sample crystallinity increased with time, and reached a plateau after 4 hours and remained relatively stable after that. FTIR spectra showed an increase of the concentration of hydrogen bonds with time. Rheological measurements indicated that both the storage and loss moduli (G' and G") increased gradually with time and showed a sudden increase at 3-4 hours. These findings provided fundamental understanding of a unique crystalline phase in the liquid state for the behavior of dextran molecules and serve as a model possibly for other carbohydrates in solution and their aggregation, which in turn helps improve the quality of carbohydrates containing concentrated semi-solid foods.

description: Tobacco use among California’s multiethnic youth is growing, yet there is little research indicating what environmental factors impact use and prevention. Asian Americans and Pacific Islanders (AAPIs) are a very diverse population making up 13% of our state, yet we understand even less about these pro- and anti-tobacco factors.

 We propose to conduct a three-year study to understand the environmental influences associated with tobacco use in two AAPI communities: Cambodians and Chamorros. The overall goal of this project is to identify and understand the environmental characteristics associated with tobacco initiation among these two ethnic youth. The specific aims of the study are twofold: 1) to use geographic information system (GIS) mapping to identify, inventory and explore the pro- and anti-tobacco environmental characteristics in two low-income Cambodian and Chamorro populations; and 2) to study the relationship between these environmental characteristics (both pro- and anti-tobacco) and tobacco initiation and use among Cambodian youth. This study hypothesizes that the density of tobacco outlets and other pro-tobacco influences will be higher in low-income AAPI neighborhoods than in higher-income white neighborhoods. In addition, AAPI youth living in neighborhoods with high density of pro-tobacco influences and less access to anti-tobacco resources will have higher tobacco susceptibility and use.

 Environmental assessments will be conducted in three geographic areas: Long Beach and Richmond (California), and Seattle (Washington). Individual surveys of youth will be conducted in Long Beach only. Data analysis will be carried out on both the environmental data (using GIS mapping and spatial analytic techniques) and the individual survey (using multivariate techniques) to identify significant factors within each component, as well as the relationship between environmental and individual tobacco use. Findings from this study will inform further multi-level research on the environmental influences on tobacco uptake and use in California’s ethnically diverse youth populations.
Prevention of achievement loss in the middle school transition: evaluation of a social-emotional learning intervention

Year: 2008

description: Decades of research have shown a normative decline in academic performance to be associated with the transition from elementary school to middle school. Based on the idea that these difficulties stem from a lack of relevant coping skills, the current study focused on the preventive effects of a three-year social and emotional learning (SEL) program in mitigating transitional achievement loss. Quality of implementation, a crucial, but often overlooked, factor in program evaluation, is the framework through which students' intervention experiences were defined. In each intervention year, implementation was assessed through teacher-reported curriculum fidelity and teacher's perception of program quality. These factors were tested as predictors of changes in GPA and standardized test scores across the transition. Intervention dosage received over the fifth grade year emerged as a significant predictor of GPA change. Dosage was unrelated to standardized test change, though differences between genders and ethnic groups in transitional standardized test performance were found. Teachers' ratings of program effectiveness were also unrelated to outcome, but were associated with intervention dosage.

Current status. Panurginus niger Nylander, 1848, syn. nov.
Remarks. E. Eversmann (1852: 62) described this species as a male when it was actually a female. He was probably misled by the yellow clypeus, which is typical of males. V. Popov (1946: 106), after studying the type specimen, corrected this error and synonymised this species with Panurginus labiatus (Eversmann, 1852). And for a long time Panurgus clypeatus Eversmann, 1852 was accepted as a junior synonym of Panurginus labiatus (Eversmann, 1852). For the present study a lectotype was designated and then additional material from the genus Panurginus from the Urals and Siberia was examined. The lectotype specimen has brownish wings and light brown veins (vs white wings and yellow veins in P. labiatus) and is conspecific with Panurginius niger Nylander, 1848, which is widely distributed in the Eastern Palaearctic. The lectotype has an abnormally yellow clypeus and among the bees studied, there was one female of P. niger with a partially yellow clypeus (Fig. 34c), whereas the other specimens had a typically black clypeus. Thus, Panurgus clypeatus Eversmann, 1852 is recognised here for the first time as a junior synonym of Panurginus niger Nylander, 1848.

Controlled-release antimicrobials for preventing biofilm formation in food and medical applications
Creators: name: Rosenberg, Linda E.
Publisher: name: No Publisher Supplied
Year: 2008

description: Bacterial biofilms generally are more resistant to stresses as compared to free planktonic cells. Therefore, the discovery of antimicrobial stress factors that have strong inhibitory effects on bacterial biofilm formation would have great impact on the food, personal care, and medical industries. Biofilm formation can be prevented through controlled release of nature-derived antimicrobials formulated into polymer systems, especially those featuring multiple stresses as hurdles for the bacteria to overcome to prevent the development of resistance. Salicylate-based poly(anhydride-esters) have previously been shown to inhibit biofilm formation. Our research evaluated the effect of salicylate-based poly(anhydride-esters) on biofilm forming Salmonella enterica serovar Typhimurium.  The results indicate that the salicylic acid-based polymers do interfere with biofilm formation through a combination of pH effects and a thus-far-unknown mechanism. Systems combining pH stress with the controlled release of natural antimicrobials have great potential to prevent biofilm development in many environments to prevent adverse outcomes, especially implant contamination and foodborne illness.

Zammara strepens is also distributed in southeastern Brazil (Amyot & Audinet-Serville 1843; Metcalf 1963a). Zammara tympanum appears to be a more northernly distributed species with records from Brazil, Peru, Costa Rica, Guatemala, Honduras and Belize (Metcalf 1963a; Duffels & van der Laan 1985; Sanborn 2006b; 2011b; 2013). Zammara strepens has been reported from Argentina, Brazil, and French Guiana (Metcalf 1963a; Sanborn 2011b; 2013; Sanborn et al. 2011a) but no specific locations within Argentina were provided. We collected the species in the understory of the Paranense floristic province (Sanborn et al. 2011a).

Enumeration schemes for pattern-avoiding words and permutations

description: Let p=p_1...p_n and q=q_1...q_m be permutations.  We say that p contains q as a pattern if there are indices 1 [less than]= i_1 [less than] ... [less than] i_m [less than]= n such that p_{i_j} [less than] p_{i_k} if and only if q_i [less than] q_k; otherwise, p avoids q.  The study of pattern avoidance in permutations is well studied from a variety of perspectives.  This thesis is concerned with two generalizations of this pattern avoidance problem. The first generalization is that of pattern avoidance in words (where p and q may have repeated letters).  The second is that of barred permutation patterns (where p avoids q unless q is part of an instance of an even larger pattern in p). In both cases, we seek to find universal methods that count words (resp. permutations) avoiding a particular set of patterns, and automate these methods to achieve new enumeration results.

Studies of in-plane anisotropic physical properties in a-plane MgXZn1-XO
Creators: name: Saraf, Gaurav
Publisher: name: No Publisher Supplied
Year: 2008

description: MgxZn1-xO is a compound semiconductor material formed by alloying ZnO with MgO. The larger direct bandgap of MgxZn1-xO (~4eV for Mg0.33Zn0.67O) renders it useful as a barrier layer in ZnO/MgxZn1-xO based heterostructures and quantum wells. Conventionally grown c-oriented ZnO based quantum wells suffer from piezoelectric and spontaneous polarization fields, leading to lower quantum efficiency. Non-polar a-plane and m-plane ZnO based heterostructures avoid such problems.  The non-polar MgxZn1-xO films also possess in-plane anisotropic optical, acoustic and electrical properties, useful for novel polarization sensitive devices. However, as-grown non-polar MgxZn1-xO films show rougher surface compared to its c-plane counterpart, introducing serious difficulty in growth of high quality heterostructures. This dissertation addresses growth optimization and comprehensive characterization of a-plane MgxZn1-xO (0[less than or =] x [less than or =] 0.33) films on r-sapphire substrates using Metalorganic Chemical Vapor Deposition (MOCVD). Angle Resolved Auger electron spectroscopy (ARAES) indicates that Mg replaces Zn in ZnO lattice. Mg composition and films' crystal properties are characterized using transmission spectroscopy and x-ray diffraction (HRXRD), respectively. The in-plane strain along c-axis is compressive, while perpendicular to c-axis is tensile. Strain anisotropy reduces with increase in film thickness due to relaxation, with complete relaxation at film thickness of ~2µm. An increase in Mg composition increases a-axis lattice parameter and reduces c-axis lattice parameter, resulting in higher strain in the films. Scanning tunneling microscopy (STM) shows long and elongated terraces on films surface due to anisotropic surface diffusion and strain-relaxation. The direction of terraces is dependent on the miscut direction of r-sapphire substrates. The effects of film thickness, Mg composition, and deposition temperature on surface morphology have been analyzed. A red shift in the optical transmission edge is observed for electric field polarized perpendicular to in-plane c-axis as compared to that along in-plane c-axis. An increase in Mg composition reduces the separation in transmission edge. In-plane anisotropy in Hall mobility is analyzed, with mobility measured perpendicular to c-axis being higher than that along c-axis. The ZnO thin film transistors (TFTs) fabricated with devices aligned along and perpendicular to c-axis. The TFTs show high on-off ratio up to ~109.  The field-effect mobility and transconductance of ~35.5cm2/Vs and 1.09mS/mm are obtained.

Crack Propagation in Weldments

description: Crack Propagation in Weldments

The basic topic of the present study is the determination of the fatigue strength by fracture mechanics. Common fracture mechanics-based fatigue considerations, e.g., within the frame of damage tolerance considerations, are usually limited to residual lifetime determination of so-called long cracks which are often defined in conjunction with nondestructive testing. The extension of this concept to the total lifetime, as in the S-N curve approach, requires an adequate description of so-called short crack propagation which cannot be based on the DK concept and must consider the crack closure phenomenon as well as its gradual buildup at the short crack stage.
Understanding the origins of stickiness in wheat flour tortillas and devising strategies to reduce it

Year: 2008

description: This thesis aimed to determine the factors which affect stickiness in wheat flour tortilla products based on a phase/state-change approach and measurement of water activity and surface properties. Strategies were considered to reduce stickiness of flour tortillas by adding GRAS ingredients and modifying processing conditions.Commercial wheat tortillas with a wide range of stickiness were selected and equilibrated to different water activity levels (0.12-0.97). Moisture sorption isotherms were developed. Differential scanning calorimetry and mechanical spectroscopy were used to characterize the phase behavior and freezable water, wide-angle x-ray scattering to understand the effect of crystallinity, contact angle measurements to determine the surface hydrophobicity. An objective instrumental test technique was developed using a texture analyzer to quantify the stickiness in tortilla samples. X-ray microtomography was used to measure tortilla cellularity. Tortillas were prepared with Xanthan gum, carboxymethylcellulose, glycerol and propylene glycol. To understand the effect of processing conditions on stickiness, tortillas were prepared using different combinations of dough resting times, baking temperatures and cooling times after baking.Sticky tortilla showed lower glass transition temperature compared to non-sticky tortillas but both were in rubbery state at room temperature. Higher product Aw resulted in increase in surface energy which in turn caused an increase in instrumental stickiness scores as hypothesized. The polar component of surface energy was found to have a good correlation with stickiness. The sticky tortillas showed low crystallinity as compared to non-sticky tortillas.  Tortillas containing 0.5 % gums and 4 % glycerol showed increased water retention, decreased water activity, reduction in surface free energy and lower freezable water. Addition of glycerol reduced the water activity from 0.94 to 0.91. Tortillas baked at 450° F were stickier than tortillas baked at 350°. Rupture force to extend tortillas increases with increase in storage time and temperature. Storage of tortillas at lower temperatures retains freshness as was shown by reduced rupture force values.
