Influence of Wheel Materials on Thermal Load of Braking
Creators: name: Frehiwot, Alemayehu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: This paper will study the influence of wheel materials on thermal loads as a result of block braking for stopping the train. Transient thermal analyses of 3D model of railway wheel for different velocities are performed using ANSYS v12.1 workbench. The analysis is done for two wheels having different material compositions (that is bainite steel wheel-new material and CL60 which is going to be used by Ethiopian national railway vehicle). Using the thermal output as input for the transient structural analysis different stresses concentrations are observed. The results obtained for the two wheels show that, wheel 2 (Bainitic) has excellent strength, toughness and good resistance to thermal damage due to better hardness. Therefore, Bainite steel can be applied to wheels in the railway systems.

description: This thesis presents the application of composite of composite for the AALRT car body structure.In the past few decades emission of gases by the vehicle has got attention due to its immense effect on the environment. The amount a gas mitted by the vehicle is directly related with the amount of fuel consumption .the higher the fuel consumption the higher the emission by the vehicle. One of the major factors that contribute for the high fuel consumption of the vehicle is it"s high dead weight. Beside to the high fuel consumption, large dead weigh lengthens the manufacturing time of vehicle. This urges the automotive manufacture to look for a solution so as to minimize the weight of the vehicle without compromising of its static and fatigue strength, crashworthiness and stiffness. That is to have light weight vehicle system. Railway carriage can be divided into three main assemblies the running gears, car body structure and equipment (propulsion, interior, car body etc.).Thus to have light weight railway vehicle system weight reduction for the either the sub assembly shall has to be done. However the most effective approach in terms of cost and complexity of the vehicle system is to reduce the weight car body structure by using composite materials which light weight material but have the desired capability. The light weight, high crashworthiness, high fatigue and static strength, high stiffness and in corrosiveness behaviour of the composite makes them as suitable material for the car body structure as compared to the steel, the material which has been used for the railway car body structure. This thesis present the application of composite material for the AALRT car body structure .For sake of comparison of composite with that of steel static analysis has been done based using SOLIDWORK software .The result shows that composite are capable of producing lower deformation and stress ranging 40-66 5% and 32% respectively for the similar loads applied on them, while minimizing the weight of car body structure by 67%
Improving student academic productivity within remote instruction: investigating the effectiveness of virtual CICO

description: School Wide Positive Behavior Intervention and Supports is a framework by which schools can assess and develop a system of preventative strategies to decrease the likelihood of problematic behaviors. SWPBIS provides for a three tiered system of interventions with increasing supports and complexity to meet students' needs at each level. CICO was developed as a Tier 2 procedure to be implemented for students that are not demonstrating responsiveness to Tier 1 interventions within a well-developed SWPBIS framework and is intended to be implemented with students that are exhibiting disruptive non-dangerous problematic behaviors such as calling out, out of seat behavior, low productivity, and non-compliance. The research which supports the potential flexibility of CICO intervention’s applicability across a wide range of modifications empowers school administrators, teachers, and behavior specialists with the confidence to apply variations of these procedures to atypical circumstances that may arise. In March of 2020, the Covid 19 global pandemic prompts schools across America to implement a novel instructional approach which allows students to attend school remotely through online access. The move towards online schooling requires a re-imagining of how behavioral support can be delivered through virtual instruction. This study reviewed the application and effectiveness of the use of Check In/ Check Out (CICO) implemented virtually during remote instruction through a commonly shared computer based platform (i.e. Google Classroom).

description: The Mg II h&k lines are powerful diagnostics for studying the solar chromosphere. They have become particularly popular with the launch of the IRIS satellite, and a number of studies that include these lines have lead to great progress in understanding chromospheric heating, in many cases thanks to the support from 3D MHD simulations. In this study we utilize another approach to analyze observations: non-LTE inversions of the Mg II h&k and UV triplet lines including the effects of partial redistribution. Our inversion code attempts to construct a model atmosphere that is compatible with the observed spectra. We have assessed the capabilities and limitations of the inversions using the FALC atmosphere and a snapshot from a 3D radiation-MHD simulation. We find that Mg II h&k allow reconstructing a model atmosphere from the middle photosphere to the transition region. We have also explored the capabilities of a multi-line/multi-atom setup, including the Mg II h&k, the Ca II 854.2 nm and the Fe I 630.25 lines to recover the full stratification of physical parameters, including the magnetic field vector, from the photosphere to the chromosphere. Finally, we present the first inversions of observed IRIS spectra from quiet-Sun, plage and sunspot, with very promising results.

description: Shock compression of silicon (Si) under extremely high pressures (>100 Mbar) was investigated by using two first-principles methods of orbital-free molecular dynamics (OFMD) and path integral Monte Carlo (PIMC). While pressures from the two methods agree very well, PIMC predicts a second compression maximum because of 1s electron ionization that is absent in OFMD calculations since Thomas-Fermi-based theories lack shell structure. The Kohn-Sham density functional theory is used to calculate the equation of state (EOS) of warm dense silicon for low-pressure loadings (P < 100 Mbar). Combining these first-principles EOS results, the principal shock Hugoniot curve of silicon for pressures varying from 1 Mbar to above 10 Gbar was derived. We find that silicon is 20% or more softer than what was predicted by widely-used EOS models. Existing high-pressure experimental data (P = 1 - 2 Mbar) seem to indicate this softening behavior of Si, which calls for future strong-shock experiments (P > 10 Mbar) to benchmark our results.

Factors Affecting Humanitarian Supply Chain Efficiency: The Case Of International Rescue Committee (IRC) – Ethiopia Program
Creators: name: Negero, Yosef
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: This study was conducted to investigate the relationship between factors affecting humanitarian supply chain (measured in terms of seven dimensions, namely lead time, information technology, supply chain policy, training and development, socio economic factor, institutional donors, and socio political factor) and supply chain efficiency in the International Rescue Committee (IRC) – Ethiopia Program. Owning to the small number of the total population, the study had employed census survey to quantitatively assess the supposed relationship between the dependent and independent variables. Questionnaire and purposive interview were used as the formal instrument of data collection. A total of 94 questionnaires were distributed and 78 of them were filled and returned to make the response rate about (82%). The findings identify major barriers to supply chain efficiency within the IRC; in particular, longer lead time, lack of training and development, absence of consistent information communication technology, socioeconomic factors, sociopolitical factors, donor factors, and repeated change of procedures have surfaced. The overall survey findings of this particular study revealed that the supply chain management function effort of International Rescue Committee – Ethiopia Program in relation to supply chain efficiency is moderate. The findings of the study also suggested that all the dimensions of factors affecting humanitarian supply chain have statistically significant relationship both with compounded and individual measures of supply chain efficiency, though the strength of the relationship is relatively higher in the case of lead time and socio economic factor. The regression result also suggested that information technology and socio economic factor have significant impact on determining IRC's supply chain efficiency. It is suggested that International Rescue Committee –Ethiopia Program shall give special emphasis in the improvement of its lead time, information technology and socio economic factor through an efficient streamlining of its supply chain processes, on the one hand, and implement a robust supply chain enabling software on the other. The organization should avail training and development program for supply chain department, establish offline software that can work parallel with the new system and should implement consistent long term contract in all locations with relevant potential suppliers for swift and reliable operation and to speed up the emergency response activities throughout the country

description: We find a complete set of local invariants of singular symplectic forms with the structurally stable Martinet hypersurface on a $2n$-dimensional manifold. In the $\mathbb C$-analytic category this set consists of the Martinet hypersurface $Σ_2$, the restriction of the singular symplectic form $ω$ to $TΣ_2$ and the kernel of $ω^{n-1}$ at the point $p\in Σ_2$. In the $\mathbb R$-analytic and smooth categories this set contains one more invariant: the canonical orientation of $Σ_2$. We find the conditions to determine the kernel of $ω^{n-1}$ at $p$ by the other invariants. In dimension $4$ we find sufficient conditions to determine the equivalence class of a singular symplectic form-germ with the structurally smooth Martinet hypersurface by the Martinet hypersurface and the restriction of the singular symplectic form to it. We also study the singular symplectic forms with singular Martinet hypersurfaces. We prove that the equivalence class of such singular symplectic form-germ is determined by the Martinet hypersurface, the canonical orientation of its regular part and the restriction of the singular symplectic form to its regular part if the Martinet hypersurface is a quasi-homogeneous hypersurface with an isolated singularity.

description: The Coulomb interaction among massless Dirac fermions in graphene is unscreened around the isotropic Dirac points, causing a logarithmic velocity renormalization and a cone reshaping. In less symmetric Dirac materials possessing anisotropic cones with tilted axes, the Coulomb interaction can provide still more exotic phenomena which have not been experimentally unveiled yet. Here, using site-selective nuclear magnetic resonance, we find a non-uniform cone reshaping accompanied by a bandwidth reduction and an emergent ferrimagnetism in tilted Dirac cones that appear on the verge of charge ordering in an organic compound. Our theoretical analyses based on the renormalization-group approach and the Hubbard model show that these observations are the direct consequences of the long-range and short-range parts of the Coulomb interaction, respectively. The cone reshaping and the bandwidth renormalization, as well as the novel magnetism revealed here, can be ubiquitous and vital for many Dirac materials.

"It's not about me!": a phenomenological examination of work calling in higher educational leaders
Creators: name: Gibbs, Aaron
Publisher: name: No Publisher Supplied
Year: 2022

description: There are varying motivations for tenured faculty choosing to enter positions of higher education leadership. For some, the prestige of leadership and legacy building is the driving force. Conversely, there are others motivated primarily by a strong sense of work calling and a desire to be of service. These individuals choose to put aside personal accomplishment and recognition in favor of serving the greater good. As a result, the work calling orientation increases their job engagement, impacts their leadership style, and influences the organizations they build. This phenomenological study drew on Logotherapy (Frankl, 2006) and Self Determination Theory (SDT) (Ryan and Deci, 2008) to examine the role of work calling on a select few who felt “called” to move away from the classroom and into executive level leadership roles. Snowball and criterion sampling methods were employed to identify the tenured faculty. Participants took part in open-ended interviews with the goal of understanding work calling’s stages from awareness to manifestation and its impact on the organizations these individuals lead. This work also reviewed how demographics, specifically gender and ethnicity, interact with work calling in order to investigate the ways in which tenured faculty who choose to become higher education leaders.

Mothers' Satisfation Factorsat Health with Delivery Services Andassociated Institutions in West Arsi, Oromia Regional State, Ethiopia
Creators: name: Urgessa, Aman
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Background: Maternal mortality and morbidity are attributed to poor maternity quality of care. Globally, more than half a million women die annually as a result of complications of pregnancy and childbirth.So, at a time when global efforts to reduce maternal mortality have been stepped up, it is important to look at maternal satisfaction and factor affecting it. Objective: The objective of the study was to assess the mothers' satisfaction with delivery services at health institutions and associated factors in West Arsi Zone, Oromia Region, Ethiopia, 2016. Methods: A facility based cross-sectional survey with exit interview was conducted in West Arsi, Oromia Regional State, Ethiopia.Four hundred seventy seven (477) postpartum mothers wereenrolled in the study. Data was checked, coded and entered to Epi-data and was exported to SPSS version 21 for analysis. Multivariate and binary logistic regression was applied to identify the relative effect of each explanatory variable on the outcome (satisfaction). Results:This study finding showed that the overall satisfaction level of mothers with delivery service was 74.6%. Women who had no formal education, primary education and secondary education were less satisfied than women who had diploma and above (AOR= 0.851, 95%CI: 0.306, 0.863, AOR=0.399, 95%CI: 0.154, 0.730and AOR=0.569, 95%CI: 0.229, 0.412) respectively. Women who had monthly income less than 650ETB were three times more satisfied with delivery service than women who had monthly income more than 1900ETB (AOR=3.294,95% CI:1.337,8.114).Mothers who had assisted vaginal delivery were less satisfied than mothers who had caesarian section (AOR=0.31, 95%CI: 1.253, 4.115).Mothers those their privacy measures was maintained were six times more satisfied with their delivery service at health institution than those did not maintained(AOR=6.988, 95%CI:4.047,12.066). Conclusion: Only 74.6% of the mothers were satisfied from the overall level of delivery service. From this study, educational status, economical status, privacy of mothers, mode of delivery and waiting time were important predictors of level of satisfaction. Recommendation: Health institutions and health personnel should work on identified factors to increase mother's satisfaction with delivery service.Future studies should consider gathering more data from a more diverse sample to address the generalizability issue.

description: We present terahertz (THz) metasurfaces based on aligned rectangular graphene patches placed on top of a dielectric layer to convert the transmitted linearly polarized waves to circular or elliptical polarized radiation. Our results lead to the design of an ultrathin broadband THz quarter-wave plate. In addition, ultrathin metasurfaces based on arrays of L-shaped graphene periodic patches are demonstrated to achieve broadband cross-polarization transformation in reflection and transmission. The proposed metasurface designs have tunable responses and are envisioned to become the building blocks of several integrated THz systems.

Year: 2014

description: Introduction: The UN (United Nation) Millennium Development Goals (MDG 4) calls for Ethiopia to reduce child mortality by a two-third by the year 2015. The practice of appropriate health care seeking has a great potential to reduce the occurrence of severe and life-threatening childhood illnesses. However, varieties of factors have been identified as the leading causes of poor utilization of primary health care services. Poor socio-economic status, lack of physical accessibility, attitude to modern treatment, low literacy level of the mothers, large family size, number of symptoms, previous experience of child death, and perceived severity of illness were the predictors of care seeking behavior Objective: To assess mothers/care givers health care seeking behavior and its determinants for childhood illnesses Methodology: The study employed both quantitative and qualitative data collection methods with face to face prepared questionnaire for quantitative and focus group discussion for qualitative study from April 11 to May 10/2014. For quantitative data template was prepared and the data was entered, categorized, coded, and summarized using EPI 3.5.3 and transformed to SPSS version 20.00 for further analysis. Bivariate and multivariate logistic regression analysis was done to see the association of each categories of variable with the outcome variable. Significance was checked at 95% CI with p-value <0.05. Result: Regarding child hood illness 4 weeks preceding the study. 212 (33.1%) children had illness. Most of the respondents 438(68.3%) believed that there were childhood illness that could not be treated by modern medicine Mothers/ caregivers who had diploma and above education level were more likely to seek health care than those who were illiterate and Place of residence also appeared as an important factor that influenced healthcare-seeking, with residents urban more likely seek health care than rural residence. Conclusion and Recommendation: The critical predictors of healthcare-seeking identified using multivariate analysis are; place of residence, educational status of the mothers/care givers, age of the mothers /care givers, distance of the health facility and private drug shop owner. Regarding to recommendation, efforts need to be done by government and non-governmental organization to improve the mothers' health seeking behavior by providing information, education and behavioral change communication. Key words: mothers/care givers, health, care, seeking, behavior, childhood, illness, and rural district

description: G 207-9 and LP 133-144 are two rarely observed ZZ Ceti stars located in the middle and close to the blue edge of the ZZ Ceti instability domain, respectively. We aimed to observe them at least during one observing season at Konkoly Observatory with the purpose of extending the list of known pulsation modes for asteroseismic investigations and detect any significant changes in their pulsational behaviour. We determined five and three new normal modes of G 207-9 and LP 133-144, respectively. In LP 133-144, our frequency analysis also revealed that at least at three modes there are actually triplets with frequency separations of ~4 microHz. The rotational period of LP 133-144 based on the triplets is ~42 h. The preliminary asteroseismic fits of G 207-9 predict Teff=12 000 or 12 400 K and M*=0.855-0.870 MSun values for the effective temperature and mass of the star, depending on the assumptions on the spherical degree (l) values of the modes. These results are in agreement with the spectroscopic determinations. In the case of LP 133-144, the best-fitting models prefer Teff=11 800 K in effective temperature and M*>=0.71 MSun stellar masses, which are more than 0.1 MSun larger than the spectroscopic value.

description: We consider model social networks in which information propagates directionally across layers of rational agents. Each agent makes a locally optimal estimate of the state of the world, and communicates this estimate to agents downstream. When agents receive information from the same source their estimates are correlated. We show that the resulting redundancy can lead to the loss of information about the state of the world across layers of the network, even when all agents have full knowledge of the network's structure. A simple algebraic condition identifies networks in which information loss occurs, and we show that all such networks must contain a particular network motif. We also study random networks asymptotically as the number of agents increases, and find a sharp transition in the probability of information loss at the point at which the number of agents in one layer exceeds the number in the previous layer.

description: A three-dimensional (3D) Poisson solver with longitudinal periodic and transverse open boundary conditions can have important applications in beam physics of particle accelerators. In this paper, we present a fast efficient method to solve the Poisson equation using a spectral finite-difference method. This method uses a computational domain that contains the charged particle beam only and has a computational complexity of $O(N_u(logN_{mode}))$, where $N_u$ is the total number of unknowns and $N_{mode}$ is the maximum number of longitudinal or azimuthal modes. This saves both the computational time and the memory usage by using an artificial boundary condition in a large extended computational domain.

description: It was shown via numerical simulations that geometric phase (GP) and fidelity susceptibility (FS) in some quantum models exhibit universal scaling laws across phase transition points. Here we propose a singular function expansion method to determine their exact form across the critical points as well as their corresponding constants. For the models such as anisotropic XY model where the energy gap is closed and reopened at the special points ($k_0 = 0, π$), scaling laws can be found as a function of system length $N$ and parameter deviation $λ- λ_c$ (where $λ_c$ is the critical parameter). Intimate relations for the coefficients in GP and FS have also been determined. However in the extended models where the gap is not closed and reopened at these special points, the scaling as a function of system length $N$ breaks down. We also show that the second order derivative of GP also exhibits some intriguing scaling laws across the critical points. These exact results can greatly enrich our understanding of GP and FS in the characterization of quantum phase transitions.

A method for the quantitative recovery of mononucleotides from fermentation waste by precipitation
Creators: name: Longden, Jonathan
Publisher: name: Lancaster University
Year: 2015

description: Several thousand litres of liquid effluent waste are generated from the production of mycoprotein, at the Quorn Foods production facility in Billingham (UK) every day. All of this waste currently undergoes effluent treatment before disposal, despite the fact that potentially valuable mononucleotides are known to be present at significant concentrations in the waste. To harness these nucleotides, an extraction procedure was necessary. Polynucleotide extraction procedures are well reported, using methods such as precipitation, phenol-chloroform extraction or polyethylene glycol (PEG) extraction, but application of these methods for mononucleotide has not been reported, so significant adaptation of conventional protocols was necessary to ensure good recovery of mononucleotides, with specific consideration of the process operating industrially. Precipitation of nucleotides was identified as the most favourable option, after comparison of conventional laboratory-based extraction protocols. The effects of salt choice, salt molarity, solvent choice, solvent ratio, pH, incubation temperature, pre-treatment and product washing were all tested as a function of yield, purity, protein retention and salt contamination, using UV-Visible spectrophotometry, the bicinchoninic acid (BCA) assay and inductively-coupled plasma optical emission spectroscopy (ICP-OES). Results showed that 0.06 M magnesium acetate was effective at extracting mononucleotides at a yield of up to 50%, although higher yields may be possible following recommended further work. It is hoped that this method may be the basis for an industrial procedure for the large-scale extraction of nucleotides from waste, which can then be distributed to a number of active markets across the UK, Europe and beyond.
A qualitative study: parental involvement as defined by parents and special educators
Creators: name: Flores Martin, Amanda C.
Publisher: name: No Publisher Supplied
Year: 2022

description: Research indicates that parents who are involved in their children’s schools support their children’s learning at home, and engage more frequently with their children’s teachers (Reinke et al., 2019). In contrast, lower levels of parental involvement are associated with adverse behaviors at school, less social interactions, and lower academic achievement (El Nokali et al., 2010). The roles and expectations of parental involvement may differ between teachers and parents. Often, educators and school staff make assumptions about the explanations for such lack of school involvement among their students’ families (Finders & Lewis, 1994; Lightfoot, 2004). These findings clearly demonstrate that schools and teachers play a crucial role in how and to what extent parents participate in the education of their children (Benson et al., 2008). The purpose of this qualitative interview study was to explore the beliefs and practices that surround parental involvement, specifically among parents and special educators of adolescents with developmental disabilities (DD). Few studies have queried both the parents’ and teachers’ experiences working with one another. Five parents and five special educators were interviewed to identify parent and teacher perceptions of parental involvement. The following research questions were examined: (a) How do special educators and parents of students within self-contained and/or Learning and/or Language Disabilities (LLD) urban classroom settings define parental involvement? (b) What are special educators’, who teach in self-contained and/or LLD urban classroom settings, perceptions of families? (c) How do these special educators engage in and encourage parental involvement? (d) How do parents perceive their involvement in their child’s school and education? (e) What are the similarities and differences between the perceptions of parental involvement among parent and special educator pairs? In the current study, parents and teachers of adolescents with DD defined parental involvement as needs-based communication where teamwork is essential for the student. Special educators held more negative perceptions of the parents than positive perceptions, and identified expected roles of these parents. Additionally, parents perceived limited opportunities for parental involvement as well as barriers to how they could contribute to their children's education.
Travel Demand Modeling of Addis Ababa East – West Light Rail Transport

description: healthy economy, diversified and well managed transportation system needs in place. As part of the first GTP, the Federal government has built international and national railway networks. The city of Addis Ababa has gain an opportunity to have 34km of Light Rail Transport line. In order to keep any transportation systems fully functional during its service years, appropriate transport planning and modeling needed. The first step of transport planning and modeling it is to identify the needs for transportation, usually called travel demand modeling. The main objective of this research is to determine Addis Ababa East - West Light Rail travel demand by using the conventional statically oriented and trip based approach of the four step travel demand modeling technique. This modeling principle needs data of, transportation network, city level socio-economic indicators, transportation cost, travel time cost, available means of transport, and other relevant data that dictate mobility and choice of transportation mode. In order to facilitate modeling procedures TransCAD 4.5 modeling tool was utilized. In the course of modeling, Addis Ababa Transport Master Plan study serve as a basic platform for modeling by updating its input variable with 2012 base year data. The 99 Kebels of Addis Ababa used as TAZ's, transportation network developed, regression equations of trip production and attraction with updated variables used. The balanced trip production of the four trip categories, Home Based Work, Home Based Education, Home Based Others, and Non Home Based trips distributed over TAZ's. By deducting percentage of none public transport users, total number of traffics split over the three modes of public transports; Taxi, Bus and Medium Bus; and assigned over the network. By considering LRT as the fourth means of transport in the East - West corridor, traffic modal share recalculated using generalized cost, and percentage share of the four means of transport identified. As the modeling results showed, 3.5 million people reside in Addis Ababa, total number of traffic in the study corridor is 644,400, with 25.9 percentage share 167,200 passengers use LRT per day. Of all the segments, Mexico, Coca, Torhayloch and Stadium area has the highest number LRT user. These and other findings of this research compared with design document of LRT and it is concluded that the base year of 2012 traffic by itself surpass both initial and short term expected design traffic. Therefore, it is highly recommended a quick review of LRT traffic forecast is needed in order to alleviate the current over crowded in East – West LRT line.
Worldline CPT and massless supermultiplets

description: The action for a massless particle in 4D Minkowski space has a worldline time-reversing symmetry corresponding to CPT invariance of the quantum theory. The analogous symmetry of the N-extended superparticle is shown to be anomalous when N is odd, in the supertwistor formalism this is because a CPT-violating worldline-Chern-Simons term is needed to preserve the chiral U(1) gauge invariance. This accords with the fact that no massless N=1 super-Poincaré irrep is CPT-self-conjugate. There is a CPT self-conjugate supermultiplet when N is even, but it has $2^{N+1}$ states when N/2 is odd (e.g. the N=2 hypermultiplet) in contrast to just $2^N$ when N/2 is even (e.g. the N=4 Maxwell supermultiplet). This is shown to follow from a Kramers degeneracy of the superparticle state space when N/2 is odd.

description: Optical microcavities supporting exciton-polariton quasi-particles offer one of the most powerful platforms for investigation of rapidly developing area of topological photonics in general, and of photonic topological insulators in particular. Energy bands of the microcavity polariton graphene are readily controlled by magnetic field and influenced by the spin-orbit coupling effects, a combination leading to formation of linear unidirectional edge states in polariton topological insulators as predicted very recently. In this work we depart from the linear limit of non-interacting polaritons and predict instabilities of the nonlinear topological edge states resulting in formation of the localized topological quasi-solitons, which are exceptionally robust and immune to backscattering wavepackets propagating along the graphene lattice edge. Our results provide a background for experimental studies of nonlinear polariton topological insulators and can influence other subareas of photonics and condensed matter physics, where nonlinearities and spin-orbit effects are often important and utilized for applications.
