Creators: name: Kefelegne  Nega
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2021
Subjects: Service quality dimensions, customer satisfaction, SERVQUAL

description: This study is set out to examine the Effect of service quality on customer satisfaction in Ethiopian road authority central garage. Quantitative means of data collection method is employed to collect the data through questionnaire. Stratified sampling technique is used to select the sample size and samples of 243 internal customers are taken to undertake the study. For the purpose of the study primary data were collected by using Likert scale based questionnaire. And the data were analyzed using descriptive statistics and using statistical tools such as mean, correlation, and regression analysis with SPSS version 20. Correlation and multiple regressions were used to investigate the relationship between dependent and independent variables. The results of this study indicate that, all the service quality dimensions (tangibility, reliability, responsiveness, empathy and assurance) have positive and significant relationship with customer satisfaction in Ethiopian road authority central garage. The correlation results indicate the highest and strong relationship is found between Responsiveness and customer satisfaction and the least but positive relationship between Assurancethat is a positive correlation between the dimensions of service quality and customer satisfaction. The results of the regression test showed that offering quality service have positive effect on overall customer satisfaction. The finding of the analysis showed that, the performance of CEMAD in providing quality service is not in a position to meet the expectation of the customer. Low service quality leads low customer satisfaction. Based on this, in order to improve performance of the CEMAD, the researcher suggested that, the service deliverer has not supported by modern equipment enough man power; The CEMAD employees delivering the services are not neat, disciplined, and professional in their appearance. Therefore the CEMAD should exert its maximum effort to change this result and should work on all the service quality dimensions to improve and maintain its customer satisfaction.

description: We present a spatially resolved, high-spectral resolution (R=12000) K-band temporal monitoring of Rigel using AMBER at the VLTI. Rigel was observed in the Bracket Gamma line and its nearby continuum in 2006-2007, and 2009-2010. These unprecedented observations were complemented by contemporaneous optical high-resolution spectroscopy. We analyse the near-IR spectra and visibilities with the 1D non-LTE radiative-transfer code CMFGEN. The differential and closure phase signal exhibit asymmetries that are interpreted as perturbations of the wind. A systematic visibility decrease is observed across the Bracket Gamma. During the 2006-2007 period the Bracket Gamma and likely the continuum forming regions were larger than in the 2009-2010 epoch. Using CMFGEN, we infer a mass-loss rate change of about 20% between the two epochs. We further find time variations in the differential visibilities and phases. The 2006-2007 period is characterized by noticeable variations of the differential visibilities in Doppler position and width and by weak variations in differential and closure phase. The 2009-2010 period is much more quiet with virtually no detectable variations in the dispersed visibilities but a strong S-shape signal is observed in differential phase coinciding with a strong ejection event discernible in the optical spectra. The differential phase signal that is sometimes detected is reminiscent of the signal computed from hydrodynamical models of corotating interaction regions. For some epochs the temporal evolution of the signal suggests the rotation of the circumstellar structures.

description: We propose a one-step scheme to implement a multiqubit controlled phase gate of one qubit simultaneously controlling multiple qubits with three-level atoms at distant nodes in coupled cavity arrays. The selective qubit-qubit couplings are achieved by adiabatically eliminating the atomic excited states and photonic states and the required phase shifts between the control qubit and any target qubit can be realized through suitable choices of the parameters of the external fields. Moreover, the effective model is robust against decoherence because neither the atoms nor the field modes during the gate operation are excited, leading to a useful step toward scalable quantum computing networks.

description: We reinvestigate the fate of the Vainhstein mechanism in the minimal model of dRGT massive gravity. As the latter is characterised by the complete absence of interactions in the decoupling limit, we study their structure at higher energies. We show that in static spherically symmetric configurations, the lowest energy scale of interactions is pushed up to the Planck mass. This fact points towards an absence of Vainshtein mechanism in this framework, but does not prove it. By resorting to the exact vacuum equations of motion, we show that there is indeed an obstruction that precludes any recovery of General Relativity under the conditions of stationarity and spherical symmetry. However, we argue that the latter are too restrictive and might miss some important physical phenomena. Indeed, we point out that in generic non spherically symmetric or time-dependent situations, interactions arising at energies arbitrarily close to the energy scale of the decoupling limit reappear. This leads us to question whether the small degree of spherical symmetry breaking in the solar system can be sufficient to give rise to a successful Vainshtein mechanism.

description: We report in this paper, measurements of the nonlinear susceptibility χ_sub3(T) in the metamagnetic heavy fermion (HF) compound UPt3. At high temperatures, χ_sub3(T) < 0 and small. It turns positive for T less than 35K, forms a peak at T = 10K and then decreases to zero with further decreasing temperature. The peak in χ_sub3 occurs at a temperature T3 roughly half of T1, the temperature of the maximum in the linear susceptibility. We present results on URu2Si2 and UPd2Al3 to show that this feature is common to other HF materials. A two level model to describe the metamagnetic transition, with separation between the levels being the only energy scale, captures all experimentally observed features.

description: The Occurrence of dyes in aquatic ecosystems has become a serious environmental problem. Studying environmental awareness viz a viz to the economic standpoint, the application of low-cost and ecofriendly adsorbents has been investigated widely as an alternative to the removal of dyes. This study explores the possibility of using waste tyre based activated carbons for the removal of synthetic dyes from aqueous solution. Prior to the adsorption process, the activated carbon was synthesized through a chemical activation method using Ethanoic-KOH as an activating agent. The parameters in the study were impregnation ratio, carbonization temperature, and impregnation time, which were selected through one variable at a time study. The optimum values found were 700℃ carbonization temperature, 16.18 hr. of impregnation time, and not adding Ethanoic-KOH, these sample removed 90.47% of Methylene blue, using face-centered central composite design methodology. The optimized sample had a surface area of 53 m2 /gm. This sample was demineralized by using NaOH and H2SO4 in a 1:1 ratio and the surface area was enhanced to 257 m2 /gm. Besides, while demineralization a massive decrement of metals from the waste and optimized samples were seen. Effect of adsorption dosage, pH, initial dye concentration, temperature, and contact time on percentage reduction of Methylene Blue and Methylene blue number were studied. The maximum removal of Methylene Blue was found at 1.2 g adsorbent dosage, 120 min contact time, pH of 8, Temperature of 20℃, and initial dye concentration of 10 mg/l. Kinetics and isotherm studies showed that the adsorption mechanism of Methylene Blue using waste tyre Activated Carbon samples follows pseudo-second-order while both Temkin adsorption isotherm model well fitted the adsorption data with R2 values of 0.9744, 0.9713, 0.9821, and 0.9901 for the optimized, NaOH, NaOH : H2SO4 (1:1), and H2SO4 demineralized samples respectively. Furthermore, Intraparticle diffusion models indicated that the kinetics of the Methylene Blue adsorption on the waste tyre Activated Carbon do not entirely depend on diffusion, rather other factors were responsible also. To sum up with, waste tyre can be a good precursor for Activated Carbon production and can be used to remove Methylene Blue from wastewater.

description: A novel, model free, approach to experimental closed-loop flow control is implemented on a separated flow. Feedback control laws are generated using genetic programming where they are optimized using replication, mutation and cross-over of best performing laws to produce a new generation of candidate control laws. This optimization process is applied automatically to a backward-facing step flow at Re=1350, controlled by a slotted jet, yielding an effective control law. Convergence criterion are suggested. The law is able to produce effective action even with major changes in the flow state, demonstrating its robustness. The underlying physical mechanisms leveraged by the law are analyzed and discussed. Contrary to traditional periodic forcing of the shear layer, this new control law plays on the physics of the recirculation area downstream the step. While both control actions are fundamentally different they still achieve the same level of effectiveness. Furthermore the new law is also potentially easier and cheaper to implement actuator wise.

description: In this talk I will show that X-ray spectral observations of the ATHENA mission can constrain the equation of state(EOS) of superdense matter. We use our well-constrained continuum-fitting method to determine the mass and radius of a neutron star. Model spectra of the emission from a neutron star were calculated using the atmosphere code ATM24. In the next step, those models were fitted to simulated spectra of the neutron star calculated forATHENA’s Wide Field Imager (WFI) detector, using satellite calibrationfiles. To simulate the spectra we assumed three different values of effective temperature, surface gravity, and gravitational redshift. These cases relate to three different neutron star masses and radii. This analysis allows us to demonstrate both the precision of our method and the need for a fast detector onboard ATHENA. A large grid of theoretical spectra was calculated with various parameters and a hydrogen–helium–iron composition of solar proportions.These spectra were fitted to the simulated spectrum to estimate the precision of mass and radius determination. In each case, we obtained very precise values with errors in the range 3%–10% for mass and 2%–8% for radius within 1σ confidence. We show here that, with the ATHENA/WFI detector, such a determination could be used to constrain the EOS of superdense neutron star matter. This talk is based on the paper by Majczyna et al. (2019; ApJ 888, 123)

description: VISVE, a computational tool developed with the support of the Office of Naval Research (ONR), is specifically designed for analyzing marine propeller performance in turbulent flows. To facilitate the computational demands of the simulations, all the development work and tests were conducted on TACC-affiliated supercomputers. The performance of the code was analyzed through profiling, identifying the most time-consuming components. To optimize the computational efficiency, the code was parallelized using a hybrid OpenMP and MPI strategy. Scalability tests were conducted on the ICX nodes, Stampede2, with a focus on a 3-D propeller operating within turbulent flows. This study contributes to the development of a robust numerical model, which can be effectively utilized for analyzing propeller performance in complex turbulent flow conditions. The parallelization strategy employed in VISVE significantly enhances its computational capabilities, making it suitable for high-performance computing platforms at TACC.

description: Chromium is one of the most hazardous pollutants in industrial effluents, the leather industry takes larger share. The goal of this study was, thus, to investigate the adsorptive capacity of eggshell-based cobalt oxide and zinc oxide nano composite for the removal of Cr (VI) ions from its aqueous solutions. The eggshell was cleared and pre-treated with hydrochloric acid. Then, the eggshell-based cobalt oxide and zinc oxide nano composite was synthesised by crafting cobalt and zinc oxides on treated eggshell and then calcinated at 600 °C for 3 hrs. The synthesized composite was characterized using scanning electron microscope, Fourier transform infrared spectroscopy, X-ray diffraction, particle size analyser, BET, differential scanning calorimeter, thermal gravimetric analyses. The results reveal that the composite fulfils nano composite materials and adsorbents requirements. As was seen from the SEM image and evidenced from particle size analyser, the composite particles size was found in the range of 1.5–5 nm, the average being 2.4 nm. Besides, BET results showed that the nano composite had considerable surface (142 m2 /g) for adsorption. The nano composite as was studied using TGA showed that it can sustain up to 600 °C temperature. Moreover, the nano composite was 68.5% crystal as shown in the XRD analysis. The adsorption efficacy of the synthesized composite was evaluated to investigate the effect of adsorption time, adsorbent dose and initial concentration of chromium (VI). The adsorptions were carried out over time of 60-120 minutes, pH from 1-3, adsorbent dose from 1-2 g/L and initial concentration from 30-60 mg/L. These optimum parameters for removal of chromium (VI) from aqueous solution was obtained using Response Surface Methodology (RSM). The optimum chromium (VI) removal of 94.8% were obtained at absorption time of 90 minutes, pH of 2, adsorbent dose of 1.5 g/L and initial concentration of 45 mg/L. On top the adsorption process optimization, the adsorption kinetics and isotherm models were studied. A pseudo -second-order with R-squared of 0.989 and Langmuir isotherm with R-squared of 0.999 mathematical models were found to represent the kinetics and isotherm of Cr (VI) adsorption on the surface of the eggshell-based cobalt oxide and zinc oxide nano composite.

description: We present a detailed AC susceptibility investigation of the fluctuation regime in the insulating cubic helimagnet Cu2OSeO3. For magnetic fields mu_0 H >= 200 mT, and over a wide temperature range, the system behaves according to the scaling relations characteristic of the classical 3D Heisenberg model. For lower magnetic fields the scaling is preserved only at higher T, and becomes renormalized in a narrow T range above the transition temperature. Contrary to the well-studied case of MnSi, where the renormalization has been interpreted within the Brazovskii theory, our analysis of the renormalization at H = 0 shows the fluctuation regime in Cu2OSeO3 to lie closer to that expected within the Wilson-Fischer scenario.

Polish feminism between East and West
Creators: name: Grabowska, Magdalena
Publisher: name: No Publisher Supplied
Year: 2009

description: By focusing on the unique forces that shape women’s movements in the post-communist context, this dissertation asks if the established geopolitical and theoretical frameworks, based on dichotomies between East and West, South and North can be utilized outside these locations. Or is a new framework necessary to fully understand the specific processes that are at work in the ambiguous “Second” World location? Chapter One, traces the individual and collective trajectories of Polish women’s movement to the 19th century anti-partition mobilizations, the Second World War, the 1968 students’ liberation movement, the “Solidarity” labor union, and the 1990s Polish debate on abortion. Chapter Two identifies two elements as crucial for the unique development of transnational activism in the context of CEE: 1) its trajectory (“late” arrival into the international feminist space) and 2) the domination and critique of the EU “gender mainstreaming” paradigm within gender social justice discourses. Chapter Three recognizes the 1990s “abortion debate” became in impulse for the feminisms to move beyond the borders of the conservative nation state and bring the question of women’s sexual rights into the supranational political spaces and became a momentum for the emergence of versatile, vibrant mobilizations for gender and sexual justice in Poland and (e.g. European Court of Justice decision in the case of Alicja Tysiac against the Polish state). Chapter Four argues that secularism that had become, a necessary feminist response to violent and oppressive discourses that act to restrict women’s sexualities and rights, has also hindered feminist connectivity with religious women. In Poland a purification of the sexuality, emergence of the “political Catholicism” and “secular feminism” produced the subaltern, traveling identities of Catholic feminists. Chapter Five examines re-appropriation of the Anti-Semitic language of civic strangeness, historically represented by Polish Jews to the experience of sexual minorities. In conclusion this dissertation delineates two factors as decisive for current positionality of the “Second” world in the transnational feminist theory and practice: the rejection of Marxism as representing the colonial practices from the East (Russia, Soviet Union), the priotization of the supranational engagements with the European Union and Western Europe rather then Third World.

description: We compare predictions of cooled masses and cooling rates from three stripped-down Semi-Analytic Models (SAMs) of galaxy formation with the results of N-body+SPH simulations with gas particle mass of 3.9x10^6 Msun, where radiative cooling of a gas of primordial composition is implemented. We also run a simulation where cooling is switched on at redshift ~2, in order to test cooling models in a regime in which their approximations are expected to be valid. We confirm that cooling models implemented in SAMs are able to predict the amount of cooled mass at z=0 to within ~20 per cent. However, some relevant discrepancies are found. (i) When the contribution from poorly resolved halos is subtracted out, SAMs tend to under-predict by ~30 per cent the mass that cools in the infall-dominated regime. (ii) At large halo masses SAMs tend to over-predict cooling rates, though the numerical result may be affected by the use of SPH. (iii) As found in our previous work, cooling rates are found to be significantly affected by model details: simulations disfavour models with large cores and with quenching of cooling at major mergers. (iv) When cooling is switched on at z~2, cold gas accumulates very quickly in the simulated halos. This accumulation is reproduced by SAMs with varying degrees of accuracy.

description: Pile foundations are intended to transmit heavy loads into the ground. Static pile load tests performed at full scale were considered in the establishment and simulation of the load-carrying capacity of each three considered piles. In a comparison of simulation of the full-scale test, the parameters considered include actual stratification property and dimensions, loading magnitudes, and loading durations were investigated and simulated. In this study, three different projects withstatic compression pile load tests conducted have been considered for simulation with a diameter of piles 600mm and 800mm and depth range from 17m to 28m. In this paper, the initial step was the determination of soil parameters required for simulating these static compression load tests using ABAQUS 2017 software and followed by modeling of these tests considering loading and unloading stages and durations according to actual load tests performed. The results found in the simulation of the actual pile load test give a reasonably good estimation for performed tests witha result variation of 28% and 12% maximum and minimum respectively. This would be a good input to estimate future pile load test plans before execution of the test as well as execution of theproject
Consciousness raised

description: The personal is political: this revelation sent ripples through the women’s liberation movement in the late 1960’s and early 1970’s and inspired a feminist practice to discuss personal experience openly and collectively in a safe and supportive context. This practice came to be known as consciousness raising (CR). CR helped women recognize that individual struggles were, by and large, fueled by gender politics. A historical practice with a precipitous rise and fall, CR has been revitalized and improved through medical support and education websites. By grounding access to valid health information in the trusted and proven feminist practice of CR, these web based resources add credibility and familiarity to a complex subject. The contemporary American expectation that information be available on demand makes web based resources extremely important. Medical support and education websites that incorporate computer- mediated communication create avenues to medical information – both professional and experiential – that can result in an increased level of health literacy. This project examines the feminist practice of consciousness raising through a comparative case study of face-to-face and web-based health literacy projects. In both contexts group discussions of personal realities establish links between subjective experience and larger political themes. This evaluation of the evolution of CR focuses on the Boston Women’s Health Book Collective, an early, long-lasting and effective CR group, and Breastcancer.org, a more recent but rapidly expanding web-based tool for raising women’s consciousness. Both sites focus on health literacy through education, support and collective discussion. They provide the basis for an in-depth examination of successful CR communication strategies. This study will explore the methods of information distribution utilized by the Boston Women’s Health Book Collective and frame those against a web-based breast cancer support and education website, Breastcancer.org. This comparison will establish a connection in the modes of information distribution, communication strategies and support offered via face-to-face and text based CR. I highlight the effectiveness of breast cancer support and education sites that use a new form of CR to advocate for health literacy. Health literacy does not make an individual a medical expert; rather it provides the necessary information and perspective for women to play an active role in their health care plan. Themes that will be present throughout this project include: consciousness raising as a feminist practice, the role of the Boston Women’s Health Book Collective within the women’s health movement, breast cancer support and education websites that foster health literacy, and the exchange of ideas, experience and medical knowledge – that is CR – that ties them together.

description: In this master's thesis, I examine 100+ Men Against Domestic Violence, a training program that was offered to Rutgers University students, faculty, and staff in September 2008 in New Brunswick, New Jersey. This training program was designed to educate and empower men to end domestic violence in their communities by utilizing the bystander intervention model which aims to change underlying social norms and attitudes that contribute to the problem of violence against women. Ten months following the training program, interviews were conducted with several men that attended the program in order to evaluate the program. Both the training program and the interviews will be examined in this paper.I will introduce the topic area of violence against women; provide theoretical frameworks in which to examine these issues; outline the 100+ Men Against Violence training program; present the evaluation of the program; and provide further deliberation on the implications of this research and suggestions for the future. This paper particularly focuses on bystander intervention, which is a major component of the 100+ Men Against Domestic Violence Program, in order to evaluate the efficacy of its principles as a primary prevention program.

description: This is the finalized Unified Field Equation developed by Eric Franz (2025). It unifies all four fundamental forces — gravity, electromagnetism, strong nuclear, and weak nuclear — into a single system through time-frequency-energy modulation. This model introduces a new perspective on time distortion, field resonance, and the deep structure of mass and energy.

Core Equation:Δt = μ × (r × h) / (m × c²) × √(1 - 2GM / rc²)

Where:– Δt = Time distortion– μ = Frequency modulation (resonance)– r = Radius / confinement distance– h = Planck’s constant– m = Mass– c = Speed of light– G = Gravitational constant– M = Gravitational body mass

Highlights:– Bridges general relativity and quantum mechanics– Explains nuclear binding and decay through resonance– Scales across space-time and atomic interactions– Opens potential for new tech in propulsion, energy, and time-based communication

description: The power harvesting capacity of wind turbines is the major performance metric that depends on weather conditions and controller accuracies. This dissertation work presents a statistical estimation of wind power. It examines the impact of uncertainties on wind power generation. Also, new control approaches are developed to improve the output power of horizontal axis wind turbines. Statistically, the wind power capacity of the Adama II wind farm site is estimated. In 2019, the yearly average wind power density of the site is 532 W/m2 . The uncertain weather conditions are one of the many factors that affect the energy-yielding ability of wind turbines. Thus, this study statistically investigates uncertain weather conditions, parametric uncertainties, and analyses the performance of wind turbines using real-time data. Due to variations in an annual average air density and yearly average wind speed, and uncertainties in aerodynamic parameters of a wind turbine, the annual uncertainty in the output power is 32% of the rating of the selected 1.5 MW wind turbine. The linearized model of doubly-fed induction generator (DFIG) based wind turbine performance is estimated by using the system identification technique. The parametric uncertainty in this model and its effects on the dynamic and steadystate performances of the DFIG based wind turbine are examined. It caused instability in the dynamic model and influenced the steady-state performances. The output power of wind turbines that operate under uncertainty is improved by three new approach control strategies: model identification (MI) based, Adaptive Network Fuzzy Inference System (ANFIS), and the Mandani Fuzzy Inference System (MFIS). These three methods focused on improving the power conversion coefficient of wind turbines by incorporating control techniques of the turbine blade pitch actuator. The proposed control strategies are implemented and verified on a 1.5 MW DFIG based wind turbine using MATLAB/Simulink software. The results of the study show that the SI-based controller and MFIS based controller improve the output power of the wind turbine by 14.12% and 16.74%, respectively in comparison to factory test report data of the SANY SE7715 model wind turbine. The simulation results verify that the ANFIS based controller improves the output power of the Gamesa G80 wind turbine by 9.47% in comparison to data taken from the power curve of G80 manufacture (Gamesa). Thus, the researcher recommends the practical implantation of the proposed controllers to efficiently harness wind energy.

description: The behaviour of a single sub-millimetre-size water drop falling through a viscous oil while subjected to an electric field is of fundamental importance to industrial applications such as crude oil electrocoalescers. Detailed studies, both experimental and computational, have been performed previously, but an often challenging issue has been the characterization of the fluids. As numerous authors have noted, it is very difficult to have a perfectly clean water-oil system even for very pure model oils, and the presence of trace chemicals may significantly alter the interface behaviour. In this work, we consider a well- characterized water-oil system where controlled amounts of a surface active agent (Span 80) have been added to the oil. This addition dominates any trace contaminants in the oil, such that the interface behaviour can also be well-characterized. We present the results of experiments and corresponding two-phase- flow simulations of a falling water drop covered in surfactant and subjected to a monopolar square voltage pulse. The results are compared and good agreement is found for surfactant concentrations below the critical micelle concentration.

description: Der Kabarettist, Liedermacher und Romancier Rainald Grebe befasst sich in seinem Werk intensiv mit dem Gefühl der Überforderung, das seit den 1990er Jahren in Deutschland bestimmend geworden sei. Er beobachtet ein sich hieraus ergebendes Bedürfnis nach Beheimatung, Orientierung in Raum und Zeit und einer Selbstversicherung der eigenen Identität, das leicht in eine Neigung zur Ab- und Ausgrenzung anderer Personen, Gruppen und Sichtweisen umschlagen könne. Der Aufsatz arbeitet Grebes künstlerische Strategien heraus, jenes Sinn- und Identifikationsbedürfnis ernst zu nehmen, ohne dabei retrograden Tendenzen und trügerische Essentialismen einen Resonanzraum zu geben. Mit Richard Rorty lässt sich dieses Verfahren Grebes als ironisch fassen: Entweder macht Grebe mögliche Heimatentwürfe auf ihren partikularen Charakter hin transparent oder er lässt sie als rein private, auf Generalisierbarkeit von vornherein verzichtende Haltungen erscheinen.

description: A systematic study of electron or hole transfer along DNA dimers, trimers and polymers is presented with a tight-binding approach at the base-pair level, using the relevant on-site energies of the base-pairs and the hopping parameters between successive base-pairs. A system of $N$ coupled differential equations is solved numerically with the eigenvalue method, allowing the temporal and spatial evolution of electrons or holes along a $N$ base-pair DNA segment to be determined. Useful physical quantities are defined and calculated including the maximum transfer percentage $p$ and the pure maximum transfer rate $\frac{p}{T}$ for cases where a period $T$ can be defined, as well as the pure mean carrier transfer rate $k$ and the speed of charge transfer $u=kd$, where $d = N \times$ 3.4 Å is the charge transfer distance. The inverse decay length $β$ used for the exponential fit $k = k_0 \exp(-βd)$ and the exponent $η$ used for the power law fit $k = k_0' N^{-η}$ are computed. The electron and hole transfer along polymers including poly(dG)-poly(dC), poly(dA)-poly(dT), GCGCGC..., ATATAT... is studied, too. $β$ falls in the range $\approx$ 0.2-2 Å$^{-1}$, $k_0$ is usually 10$^{-2}$-10$^{-1}$ PHz although, generally, it falls in the wider range 10$^{-4}$-10 PHz. $η$ falls in the range $\approx$ 1.7-17, $k_0'$ is usually $\approx 10^{-2}$-10$^{-1}$ PHz, although generally, it falls in the wider range $\approx10^{-4}$-10$^3$ PHz. Finally, the results are compared with the predictions of Wang et al. Phys. Rev. Lett. 93, (2004) 016401, as well as experiments, including Murphy et al. Science 262, 1025 (1993); Arkin et al. Science 273, 475 (1996); Giese et al. Angew. Chem. Int. Ed. 38, 996 (1999); Giese et al. Nature 412, 318 (2001). This method allows to assess the extent at which a specific DNA segment can serve as an efficient medium for charge transfer.
