Studies in Chemical Toxicology: Synthesis of a Protected N2-Deoxyguanosine Adduct of a Cyclopenta-Polycyclic Aromatic Hydrocarbon
Creators: name: Matthews, Denise L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: A pilot synthesis was undertaken to develop synthetic routes for synthesis of N^2-deoxyguanosine adducts of a cyclopentapolycyclic aromatic hydrocarbon (CP-PAH), which have potential application for use as chromatographic standards in the 32^P-postlabeling assay. A straightforward synthetic route was developed for the synthesis of an 0^6-p-nitrophenylethyl (NPE) and 3',5'-p-toluoyl group protected derivative of 2-bromo-2'-deoxyinosine(2-BrdI) (compound 6B). The successful strategy involved sodium salt gylcosylation of 0^6-NPE-protected 2-bromohypoxanthine (4) with 2-deoxy-3.5-di-O-p-toluoyl-α-D-erythro pentofuranosyl chloride (5B) to give desired pure N-9 β glycosylation product (6B) in 39% yield. The direct glycosylation product (6B) was coupled with a CP-PAH amino alcohol, trans acenaphthene l-amino-2-ol (7), to generate the first example of a protected N^2-deoxyguanosine adduct of a CP-PAH (compound 8) in ~5% yield. This successful condensation reaction proved the usefulness of the protected 2-BrdI derivative (6B) as a precursor to target N^2-modified-2'-deoxyguanosine. The p-toluoyl groups can be removed by ammonolysis of compound 6B to give 0°6-NPE-protected-2-BrdI in 63% yield. The structural identity and purity of reaction products were confirmed by 1^H NMR and mass spectra.

description: The ability to represent others’ beliefs, desires and intentions, having a Theory of mind (ToM), is believed to decline in older age. Classic ToM tasks, however, typically encompass demands on executive functions (EF), which are also thought to decline in older age. Research to date has yet to tease apart the interaction between ToM and EF in healthy ageing. We assessed how older versus younger adults were affected by three core EF/ToM manipulations embedded within a novel false belief task: 1) Knowledge of reality 2) Congruence of perspectives between two agents 3) Congruence of perspectives between Self and Other. Our data show some comparability in the patterns of difficulty experienced between older and younger adults, where representing an agent whose belief differed from another agent’s, or from one’s own belief, was consistently more effortful than representing beliefs which were congruent between Self and Other. Nonetheless, when compared with younger adults, older adults were disproportionately affected by incompatibility between Self and Other perspectives. We discuss these results in line with conceptual and methodological implications for past and future investigations of ToM in healthy ageing.

A Numerical Model to Predict Worker Exposure from a Hand-Held Source
Creators: name: Muthedath, Premkumar
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: The dispersion of massless tracer particles released from a point source in the wake of a two-dimensional elliptic cylinder is used to model worker exposure from a hand-held source. A discrete vortex flow model is combined with a particle tracking algorithm to calculate time-averaged concentrations in the plane of the source. By space-averaging these concentrations over a computational breathing zone, estimates of breathing zone concentrations are derived. The model predictions are found to be in good agreement with measured values from wind tunnel studies. Such computational models are powerful tools to study local exhaust ventilation.

description: The aim of the paper is to explore the case of the NUP 2X35 strategic analysis campaign conducted by the Polish Armed Forces (PAF) and to identify lessons and best practices from employing the inclusive network approach to the conduct of strategic foresight analysis. The research process is centred around the following research questions: (1) What are the assumptions of the NUP 2X35 campaign of strategic analysis? (2) How was the strategic foresight analysis conducted? (3) What are the lessons and best practices from the campaign? (4) How can the case illustrate the employment of the concepts of a learning organization, open innovation and absorptive capacity in military organizations? The single case study methodology is employed as a framework for analysis. Data for analysis is collected from personal, participatory observations conducted by the authors, analysis of official documents related to NUP 2X35 released to the public, and opinions about the project expressed by key leaders of the Polish Armed Forces. The NUP 2X35 strategic foresight analysis is an interesting example of employing an inclusive, network approach to bring valuable external (civilian) knowledge into military analysis. The case shows how the armed forces recognize external knowledge, establish inclusive communities of interest grouping together military officers and civilian researchers to absorb this knowledge, how knowledge is assimilated and transformed, and finally exploited for the benefit of the Polish Armed Forces, the national defence sector and NATO. Moreover, the military pays back by increasing the awareness and understanding of defence and national security issues among the society.

Starburst Driven Galactic Superbubbles Radiating to 10 K

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Our three-dimensional hydro-dynamical simulations of starbursts examine the formation of superbubbles over a range of driving luminosities and mass loadings that determine superbubble growth and wind velocity. From this we determine the relationship between the velocity of a galactic wind and the power of the starburst. We find a threshold for the formation of a wind, above which the speed of the wind is not affected by grid resolution or the temperature floor of our radiative cooling. We investigate the effect two different temperature floors in our radiative cooling prescription have on wind kinematics and content. We find that cooling to $10$ K instead of to $10^4$ K increases the mass fraction of cold neutral and hot X-ray gas in the galactic wind while halving that in warm H$α$. Our simulations show the mass of cold gas transported into the lower halo does not depend on the starburst strength. Optically bright filaments form at the edge of merging superbubbles, or where a cold dense cloud has been disrupted by the wind. Filaments formed by merging superbubbles will persist and grow to $>400$ pc in length if anchored to a star forming complex. Filaments embedded in the hot galactic wind contain warm and cold gas that moves $300-1200$ km s$^{-1}$ slower than the surrounding wind, with the coldest gas hardly moving with respect to the galaxy. Warm and cold matter in the galactic wind show asymmetric absorption profiles consistent with observations, with a thin tail up to the wind velocity.

description: Concentrations of O6-methylguanine (O6MG), O4-methylthymidine (O4MT), and N7-methylguanine (N-7MG) were measured in the livers of Fischer 344 rats following treatment with 1,2-dimethylhydrazine (SDMH, 20 mg/kg s.c.) alone or in combination with the O6-alkylguanine transferase (AGT) inhibitor, O6-benzylguanine (O6BG, 100 mg/kg i.p. daily). Animals were sacrificed at 12, 24, 36, and 48 hours following SDMH exposure. Direct measurement of AGT demonstrated that O6BG treatment completely eliminated detectable AGT activity in the livers of treated rats. Adducts in liver DNA were quantitated by HPLC separation followed by fluorescence detection, uv absorption, and/or specific radio immunological assays (RIA). In animals exposed to SDMH alone, O6MG and O4MT disappeared, whereas animals exposed to both O6BG and SDMH showed less removal of these adducts, with significant differences between the two populations appearing at 36 and 48 hours. O6BG treatment had no effect on the removal of N-7MG. These results show that the rate of disappearance of both O6MG and O4MT is slower following AGT depletion and suggest that mammalian AGT is involved in the removal of O4MT lesions as well as O6MG lesions.

Methyl-donor Enrichment Attenuates Alcohol-induced Liver Injury: Mechanisms of Protective Action
Creators: name: Craig, Christopher Patrick
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Alcohol abuse is a major social as well as clinical problem with nearly 20% of alcoholics developing fibrosis and subsequent cirrhosis of the liver, neither of which have an acceptable cure outside of organ transplantation. Chronic alcohol abuse leads to abnormal hepatic methionine metabolism resulting in decreased levels of S-adenosylmethionine (SAM) which increasing evidence suggests is a critical factor in the development of alcohol-induced liver injury (ALI). The mitigation of disease severity in animal models of ALI has been achieved through dietary supplementation of methionine metabolites including SAM and betaine; however, the mechanism of protection remains unclear. To determine whether methyl-donor supplementation acts through modulating alcohol metabolism, mice were administered a high fat diet (HFD), or methyl-donor (MD) enriched HFD (MDHFD) with or without ethanol for 4 wks using intra-gastric intubation. Attenuation of ALI was achieved in mice administered a MDHFD as compared to those only on a HFD, an effect which was accompanied by an improved GSH:GSSG ratio, reduced hepatic cysteinylglycine levels, reduced liver:body weight and reduced cell proliferation. Blood and liver alcohol concentrations were not different between ethanol-treated groups at sacrifice; however, mean daily urine alcohol concentrations (UAC) were reduced in half by MDHFD. Stomach catalase activity was not different between alcohol treated groups in the sub-chronic study, suggesting that the lowered UAC by MDHFD was not due to altered first pass metabolism of alcoholin the stomach. Next, we investigated whether MDHFD altered hepatic ethanol metabolism. Alcohol dehydrogenase activity was similar between ethanol treated groups; however, cytochrome P4502E1 activity was reduced in half in mice fed MDHFD containing ethanol. Interestingly, acyl CoA oxidase activity along with catalase activity were elevated in mice administered a MDHFD containing ethanol. In summary, a MD-enriched diet stimulated hepatic ethanol metabolism via catalase resulting in lowered UAC in addition to improved liver detoxification capacity. Since methyl-donor supplements are being considered as potential therapies for ALI, understanding the protective mechanism of action has the potential to increase therapeutic efficacy.

description: The kernel of the $\mathbb{Z}_2^{n}$ Dirac-Dunkl operator is examined. The symmetry algebra $\mathcal{A}_{n}$ of the associated Dirac-Dunkl equation on $\mathbb{S}^{n-1}$ is determined and is seen to correspond to a higher rank generalization of the Bannai-Ito algebra. A basis for the polynomial null-solutions of the Dirac-Dunkl operator is constructed. The basis elements are joint eigenfunctions of a maximal commutative subalgebra of $\mathcal{A}_{n}$ and are given explicitly in terms of Jacobi polynomials. The symmetry algebra is shown to act irreducibly on this basis via raising/lowering operators. A scalar realization of $\mathcal{A}_{n}$ is proposed.

Characterization of Zinc as a Potential Alternative for the Reduction of Nitrate in Water Supplies
Creators: name: Bennett, Brad
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Groundwater contamination by nitrate (N03-) is caused mainly by anthropogenic sources including nitrogen fertilizers, animal wastes, septic systems and industrial processes. Due to the potential toxicity of nitrate and nitrite, the United States Environmental Protection Agency (USEPA) has established maximum contaminant levels (MCLs) of 10mg-N/L and 1mg-N/L, respectively, for the two pollutants in drinking water. The significant drawbacks associated with current treatment alternatives for nitrate-contaminated water have resulted in a large research thrust being developed toward the application of reducing nitrate to less toxic forms (i.e. N2(g) or NH4+) with zero-valent iron (Fe°). With the motivation to expand the scope of chemical reductants of nitrate, zinc (Zn°), which is electrochemically similar to iron, brass, a zinc-copper alloy, and copper (Cu°) were tested, using batch reactions, to characterize their effectiveness in reducing nitrate. Since zinc proved to be very effective in reducing nitrate, an empirical rate law was developed to determine the dependency of the reactions between zinc and oxidized nitrogen species on the initial nitrate concentration, zinc dose, and initial pH. The rate law was approximately first order with respect to the initial nitrate concentration and zinc dose, and a fractional order with respect to the initial pH was observed. A direct electron transfer mechanism between the zinc and oxidized nitrogen species is suggested and future work involving potential bench-scale applications with the zinc are proposed.

THE SYNERGY BETWEEN TECHNOLOGY AND SOLDIERS IN WARFARE – THE RUSSIAN ARMED FORCES IMAGE DURING THE WAR IN UKRAINE
Creators: name: Śliwa, Zdzisław
Publisher: name: Wiedza Obronna
Year: 2022

description: The technology has impacted all the domains of human life and one of them are military affairs. The combination of sophisticated technologies and human capacities has created new qualities based on training and education allowing to achieve advantage over less developed nations. On the contemporary battlefield this combination of people and modern weapons could cause success or lead to failure if not achieved. The range of emerging military technologies is very wide including reducing dependency on people enhancing combat efficiency. However, the technological culture of societies matters to ensure that qualified personnel could operate such a variety of systems. This is related to the values of a society and respect for other people and nations facilitating understanding and following the rules and laws, which are recognized in democratic and civilized societies. The war in Ukraine has demonstrated the importance of synergy between technology and soldiers especially when comparing the Ukrainian and Russian armed forces. There is a different perception of those armed forces based on their performance during war. The paper will focus on the Russian way of conducting aggression against sovereign Ukraine to discuss two aspects of the Russian Federation’s armed forces: technology and the human factor. The paper will use official documents and data within primary and secondary research allowing analysing and synthesising specific aspects of Russian efficiency during war.

description: Most military operations, military campaigns and wars in history have lasted longer than expected. Why do wars last longer than expected? In general, what factors determine the duration of the war? These are some of the questions that researchers think about the most. It should be noted that in order to draw reasonable conclusions about the duration of wars, they must be grouped according to their characteristics. Wars vary in intensity and scale. While some wars lasted for years, even decades, others lasted only a few days. Some wars involved only two countries, some took on a global scale. In some wars, limited battles took place and some have been engraved in history with heavy destruction. In many cases, while countries mobilize the whole society for war, some do not see the need for it. The article depicts the essence of the theories of war regarding the causes and termination, substantiates the link between them and highlights the factors that affect the duration of the war. The results of the analysis of the the Second Karabakh War and the conditions of peace have been presented. Opinions have been put forward about the outcomes of the war.

description: We provide a detailed derivation of the analytical expansion of the lunar and solar disturbing functions. Although there exist several papers on this topic, many derivations contain mistakes in the final expansion or rather (just) in the proof, thereby necessitating a recasting and correction of the original derivation. In this work, we provide a self-consistent and definite form of the lunisolar expansion. We start with Kaula's expansion of the disturbing function in terms of the equatorial elements of both the perturbed and perturbing bodies. Then we give a detailed proof of Lane's expansion, in which the elements of the Moon are referred to the ecliptic plane. Using this approach the inclination of the Moon becomes nearly constant, while the argument of perihelion, the longitude of the ascending node, and the mean anomaly vary linearly with time. We make a comparison between the different expansions and we profit from such discussion to point out some mistakes in the existing literature, which might compromise the correctness of the results. As an application, we analyze the long--term motion of the highly elliptical and critically--inclined Molniya orbits subject to quadrupolar gravitational interactions. The analytical expansions presented herein are very powerful with respect to dynamical studies based on Cartesian equations, because they quickly allow for a more holistic and intuitively understandable picture of the dynamics.

description: Using intersection and self-intersection of loops, Turaev introduced in the seventies two fundamental operations on the algebra $\mathbb{Q}[π]$ of the fundamental group $π$ of a surface with boundary. The first operation is binary and measures the intersection of two oriented based curves on the surface, while the second operation is unary and computes the self-intersection of an oriented based curve. It is already known that Turaev's intersection pairing has an algebraic description when the group algebra $\mathbb{Q}[π]$ is completed with respect to powers of its augmentation ideal and is appropriately identified to the degree-completion of the tensor algebra $T(H)$ of $H:=H_1(π;\mathbb{Q})$. In this paper, we obtain a similar algebraic description for Turaev's self-intersection map in the case of a disk with $p$ punctures. Here we consider the identification between the completions of $\mathbb{Q}[π]$ and $T(H)$ that arises from a Drinfeld associator by embedding $π$ into the pure braid group on $(p+1)$ strands; our algebraic description involves a formal power series which is explicitly determined by the associator. The proof is based on some three-dimensional formulas for Turaev's loop operations, which involve $2$-strand pure braids and are shown for any surface with boundary.

description: Incineration has been chosen as the preferred method for disposing of animal carcasses containing radioactive microspheres at East Carolina University. Routine surveys of ash from successive non-radioactive burns have shown significant contamination from previously incinerated microspheres. Past studies on microsphere incineration quantified the amount of activity retained in ash, but did not address any subsequent releases. This topic was not considered in earlier studies because, in most cases, the carcasses were placed in some type of container to facilitate recovery of ash, preventing contamination of the incinerator refractory. Five sets of controlled burns were performed to quantify the subsequent releases of the microsphere radioisotopes Ce-141, Sn-113, Ru-103, Nb-95, and Sc-46. Each set consisted of three successive burns. The first burn of each set incinerated a non-radioactive carcass, the second burn, a radioactive carcass, and the third, a non-radioactive carcass. In all of the burns, the carcasses were placed directly on the incinerator refractory floor, as is the standard procedure during normal operations. The data collected document that significant subsequent releases of activity from the refractory do occur. This results in contamination of ash from non-radioactive burns. The actual amount of activity released varies with each isotope. These findings have caused East Carolina University to re-evaluate the quantities of radioactivity which may be burned, and to initiate a program to monitor all incinerator ash for gamma emitting radionuclides.

description: With pervasive and persistent changes affecting education, educators are called to challenge current paradigms about best practices in instructional design and delivery and redefine how they are integrated into the curriculum. The purpose of this article is to introduce a model designed to support the new paradigm for best practices in education. The model recognizes the transformational nature of teaching and learning, and equips educators with the tools to proactively and continuously adapt to change. Implications for practice include developing curriculum that meets learner orientations and responds to labour market demands for program currency and graduate preparedness. The term "best practices" has become standard nomenclature pervading the teaching and learning discipline. As educators, we refer to best practices as our toolkit of classroom activities, strategies, and techniques developed over years of honing our craft and sharing our expertise with colleagues. Armed with exemplary teaching practices, we strive to motivate learners and enhance the enjoyment and effectiveness of learning (PE Central, 2002). Dialoguing about best practices to discern the most effective teaching tools is a central theme at professional development conferences and around the proverbial water cooler in the workplace. We engage in the continuous exploration for and experimentation with the practices that define excellence in our profession.
Band structure and electron-phonon coupling in H$_3$S:a tight-binding model

description: We present a robust tight-binding description, based on the Slater-Koster formalism, of the band structure of H$_3$S in the {\em Im}$\bar{3}${\em m} structure, stable in the range of pressure $P = 180-220$ GPa. We show that the interatomic hopping between the 3$s$ and 3$p$ orbitals (and partially between the 3$p$ orbitals themselves) of sulphur is fundamental to capture the relevant physics associated with the Van Hove singularities close to the Fermi level. Comparing the model so defined with density functional theory calculations we obtain a very good agreement not only of the overall band-structure, but also of the low-energy states and of the Fermi surface properties. The description in terms of Slater-Koster parameters permits us also to evaluate at a microscopic level a hopping-resolved linear electron-lattice coupling which can be employed for further tight-binding analyses also at a local scale.

Evaluation of a Low-Cost Compartmentalized Bag MPN Method for the Detection and Quantification of E. coli in Fecally Contaminated Drinking Water
Creators: name: Pierson, Katherine A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Fecally contaminated drinking water contributes to 1.8 million diarrheal disease deaths every year. There is currently no simple, affordable, readily available method for people to test the quality of their drinking water without having access to a laboratory, making testing inaccessible for many people who are uncertain about the quality of their drinking water. There is a need for a quantitative test for fecal contamination in drinking water that is low-cost, can be used outside a laboratory, and gives results comparable to currently accepted standard methods. The purpose of this work was to evaluate a novel low-cost Most Probable Number (MPN) assay in a compartmentalized plastic bag for the enumeration of E. coli in drinking water. Test waters were natural surface waters with and without the addition of primary sewage effluent. Lauryl Tryptose Broth with X-glucuronide, a chromogenic substrate specific for E. coli, was added to 100 mL of test water in a 5-compartment bag. Replicate samples were incubated for 24-48 hours at 27°C, 37°C, and 44.5°C. For comparison to a standard method, samples were analyzed using both the plastic bag and the IDEXX Colilert® Quanti-Tray 2000. Results obtained from experiments using Morgan Creek natural surface water showed that at incubation temperatures of 37°C or 44.5°C for 24 hours of incubation, no significant differences in E. coli concentrations were found between the compartmentalized bag tests (CBT) and the Quanti-Tray (QT) (p=0.3501 and p=0.4155 for 37°C and 44.5°C, respectively). At an incubation temperature of 27°C for 48 hours incubation, there was no significant difference in E. coli concentrations between the CBT and the QT (p=0.3125). These results suggest that the CBT gives results comparable to a standard method for the detection of E. coli in drinking water, and can potentially be incubated at non-standard temperatures. The compartmentalized bag test is a potential low-cost alternative to standard drinking water quality tests for low-resource settings.
A note on APN permutations in even dimension

description: APN permutations in even dimension are vectorial Boolean functions that play a special role in the design of block ciphers. We study their properties, providing some general results and some applications to the low-dimension cases. In particular, we prove that none of their components can be quadratic. For an APN vectorial Boolean function (in even dimension) with all cubic components we prove the existence of a component having a large number of balanced derivatives. Using these restrictions, we obtain the first theoretical proof of the non-existence of APN permutations in dimension 4. Moreover, we derive some contraints on APN permutations in dimension 6.

Time-Delayed Treatment of Effluent For Intermittent Operating Facilities Using Low Pressure Pipe Treatment
Creators: name: Blake, M. Travis
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1985

description: Many facilities—such as weekend camps, retreats, and churches—operate for only a few days out of the week. The cost for wastewater treatment is one of the larger cost to these intermittent operating facilities. Given these two factors and possible poor soil conditions at the site, the facility may not be able to acquire a permit for a proper treatment facility or afford to install a properly-sized treatment system. Given these conditions, a treatment system was designed for such a facility using an unusually large storage capacity and a smaller low pressure pipe absorption area than would be required . This paper describes the process followed to arrive at this system's design, as well as its installation, maintenance and operation.
