description: Using direct numerical simulation of hydrodynamic turbulence with helicity forcing applied at all scales, a near-maximum helical turbulent state is obtained, with an inverse energy cascade at scales larger than the energy forcing scale and a forward helicity cascade at scales smaller than the energy forcing scale. In contrast to previous studies using decimated triads, our simulations contain all possible triads. By computing the shell-to-shell energy fluxes, we show that the inverse energy cascade results from weakly non-local interactions among homochiral triads. Varying the helicity injection range of scales leads to necessary conditions to obtain an inverse energy cascade.

description: We present an empirical model for single pulses of radio emission from pulsars based on gaussian probability distributions for relevant variables. The radiation at a specific pulse phase is represented as the superposition of radiation in two (approximately) orthogonally polarized modes (OPMs) from one or more subsources in the emission region of the pulsar. For each subsource, the polarization states are drawn randomly from statistical distributions, with the mean and the variance on the Poincaré sphere as free parameters. The intensity of one OPM is chosen from a log-normal distribution, and the intensity of the other OPM is assumed to be partially correlated, with the degree of correlation also chosen from a gaussian distribution. The model is used to construct simulated data described in the same format as real data: distributions of the polarization of pulses on the Poincaré sphere and histograms of the intensity and other parameters. We concentrate on the interpretation of data for specific phases of PSR B0329+54 for which the OPMs are not orthogonal, with one well defined and the other spread out around an annulus on the Poincaré sphere at some phases. The results support the assumption that the radiation emerges in two OPMs with closely correlated intensities, and that in a statistical fraction of pulses one OPM is invisible.

description: The paper investigates the conflicting findings in empirical studies linking land productivity to plot size, livestock ownership, investment in farm assets, and land improvement practices. The conflicting impacts found are partly as a result of different model specifications, the type of data used – panel or cross sectional data – and possibly due to imperfections in rural markets. We control for these problems using household and plot level panel data from rural farmers in Uganda. We find that ownership of cattle has a negative and significant impact on land productivity. Investment in farm related assets, land improvements and other small livestock, however, significantly increases productivity. The conflicting impacts are a result of measurement error. The plot size inverse productivity is robust to different specifications and is largely explained by plot-specific unobserved heterogeneity and imperfections in rural markets.

description: This paper demonstrates a comprehensive methodology to assess the viability of an environmental management plan which has long-run economic and ecological impacts. The case study under consideration is the implementation of a water resource management plan in a water scarce region of the world, namely Cyprus. Specifically this plan proposes to replenish a depleting aquifer with treated wastewater. The methodology proposed first identifies the key stakeholder groups, namely farmers and the general public, who are hypothesized to derive economic values (benefits) from the implementation of this plan, and then implements stated preference methods to capture the total economic value of these benefits. Benefits are aggregated over the relevant populations of these stakeholder groups and weighed against the total costs of implementing this plan in a long-run cost-benefit analysis (CBA). An econometrically estimated time declining trajectory of discount rates is used for the CBA in order to assess the long run sustainability of the plan. The results reveal that the net benefit trajectory estimated with the time declining discount rate takes thrice as long to come to a plateau, revealing the importance of using declining discount rates, as well as capturing the entirety of benefits generated by such plans. This methodology is recommended especially for the implementation of the EU Water Framework Directive which advocates the use of the CBA and consideration of the notion of sustainability for the achievement of the good water status for all European waters.

description: The moral value is significant for everyone in every sphere of human life. Moral lessons should be properly taught among students in Schools, Colleges, Universities, Vocational training centers, Madrasas and so on. Above all, along with parents or guardians, it is the prime duty and responsibility of the educator to impart moral based values in order to develop moral qualities such as humility, integrity, truthfulness, courtesy, tolerance, sacrifice, mutual compromise etc among the youth and all level pupils. It will assist in developing positive, constructive social attitudes in new generation which prompt them to raise their moral voice against social evils. The harmonious coexistence of diverse ideologies in society requires respect for ethical and moral values. Value addition from moral education inculcates these virtues in a systematic and widely acceptable manner. Morality is basically the knowledge of knowing what is right and what is wrong. With the morality human being can preserve their sense of humanity and empathy for others’ sorrows while at the same time people can retain their sense of unselfishness for others. Here in this research paper, the “Universal Education Theory” is explained and elaborated which innovated on 2019 A.D. by Dr. Rejaul Abedin, PhD, FCMAN. The innovator who strongly believes that in the present world Universal Education Theory will be useful as it will redirect to gain moral education or to train individual through morally during their academic, social and unearthly life. Moreover, Moral education can control human mind to prevent corruption, manipulation at both the micro and macro levels.Keywords : Universal Education Theory, Moral Education, Universal Education Formula, Prevention of corruption, UE formula,

description: Learning Design has the potential to revolutionize e-learning by capturing the process of education, rather than simply content. By describing sequences of collaborative learning activities, Learning Design offers a new approach to re-use in e-learning. E-learning has a well developed approach to the creation and sequencing of content-based, single learner, self-paced learning objects. While definitions of Learning Design vary, the main elements tend to include greater focus on context dimensions of e-learning, a more activity based view of e-learning, and greater recognition of the role of multi-learner environments. While Learning Design does not exclude single learner, self-paced modes of e-learning, it draws attention to a wider range of collaborative e-learning approaches in addition to single learner approaches. This paper shows an example, which is applied to speciality of economic and rural development agricultural engineer at University of Debrecen and its implementation in the Learning Activity Management System. We created a learning design was implemented at this speciality with LAMS, which is a learning design editing and play back tool that puts the learning process, rather than collections of content, at the heart of e-learning.

description: A theoretical framework is developed for the phenomenon of non-Gaussian normal diffusion that has experimentally been observed in several heterogeneous systems. From the Fokker-Planck equation with the dynamical structure with largely separated time scales, a set of three equations are derived for the fast degree of freedom, the slow degree of freedom and the coupling between these two hierarchies. It is shown that this approach consistently describes "diffusing diffusivity" and non-Gaussian normal diffusion.

description: We construct small-world spring networks based on a one dimensional chain and study its static and quasistatic behavior with respect to external forces. Regular bonds and shortcuts are assigned linear springs of constant $k$ and $k'$, respectively. In our models, shortcuts can only stand extensions less than $δ_c$ beyond which they are removed from the network. First we consider the simple cases of a hierarchical small-world network and a complete network. In the main part of this paper we study random small-world networks (RSWN) in which each pair of nodes is connected by a shortcut with probability $p$. We obtain a scaling relation for the effective stiffness of RSWN when $k=k'$. In this case the extension distribution of shortcuts is scale free with the exponent -2. There is a strong positive correlation between the extension of shortcuts and their betweenness. We find that the chemical end-to-end distance (CEED) could change either abruptly or continuously with respect to the external force. In the former case, the critical force is determined by the average number of shortcuts emanating from a node. In the latter case, the distribution of changes in CEED obeys power laws of the exponent $-α$ with $α\le 3/2$.

description: This study explores the Igba-Nkwu, a folk name for the Igbo tribe's traditional marriage in the southeast of Nigeria. The researcher collected data over two months did the analysis concurrently using Spradley's development research sequence, a qualitative research method. According to the researcher, the recurring themes are a display of the rich cultural heritage of Nigeria, the spraying of money on the couple, and a growing cultural trend of membership of Aso-Ebi. Aso-Ebi is a folk name for the couple friends and family who chose to wear uniformly-designed clothes. The researcher noticed that doing a traditional marriage could be very expensive, and there is an uncontrolled noise level during such occasions. The result is that traditional marriages are excellent methods to unite families and display wealth. People spray money recklessly even though the government has criminalized the act. Spraying money is an undesirable practice that should be banned altogether. Other areas of concern are the increasing cost of marriage and the noise level generated in such ceremonies.

description: We present an extension of the twistor-motivated MHV vertices and accompanying rules presented by Cachazo, Svrvcek and Witten to the construction of vector-boson currents coupling to an arbitrary source. In particular, we give rules for constructing off-shell vector-boson currents with one fermion pair and n gluons of arbitrary helicity. These currents may be employed directly in the computation of electroweak amplitudes. The rules yield expressions in agreement with previously-obtained results for Z,W,γ^* --> qbar q + n gluons (analytically up to n=3, beyond via the Berends--Giele recursion relations). We also confirm that the contribution to a seven-point amplitude containing the non-abelian triple vector-boson coupling obtained using the next-to-MHV currents matches the previous result in the literature.

description: We use gravitational wave (GW) standard sirens, in addition to Type Ia supernovae (SNIa) and baryon acoustic oscillation (BAO) mock data, to forecast constraints on the electromagnetic and gravitational distance duality relations (DDR). We make use of a parameterised approach based on a specific DDR violation model, along with a machine learning reconstruction method based on the Genetic Algorithms. We find that GW provide an alternative to the use of BAO data to constrain violations of the DDR, reaching $3\%$ constraints on the violation parameter we consider when combined with SNIa, which is only improved by a factor of $\approx1.4$ if one instead considers the combination of BAO and SNIa. We also investigate the possibility that a neglected modification of gravity might lead to a false detection of DDR violations, even when screening mechanisms are active. We find that such a false detection can be extremely significant, up to $\approx10σ$ for very extreme modified gravity scenarios, while this reduces to $\approx4σ$ in a more realistic case. False detections can also provide a smoking gun for the modified gravity mechanism at play, as a result of the tension introduced between the SNIa+GW and SNIa+BAO combinations.

Notch activation induces an endothelial-to-mesenchymal transformation
Creators: name: McLean, Graeme
Publisher: name: University of British Columbia
Year: 2009

description: The Notch signalling pathway is an evolutionarily conserved intercellular signalling mechanism, and mutations in its components disrupt cell fate specification and embryonic development in organisms from nematodes to mammals. Various studies have demonstrated a critical role for Notch signalling in cardiovascular development. Patients with mutations of the Notch ligand, Jagged (JAG)l, demonstrate cardiac anomalies that are consistent with defects in endothelial-to-mesenchymal transformation that is essential for endocardial cushion formation. We demonstrate herein that constitutive activation of Notch in endothelial cells results in morphological and phenotypic changes consistent with this mesenchymal transformation. Specifically, we observe the downregulation of endothelial markers (such as vascular endothelial (VE)-cadherin) and the upregulation of mesenchymal proteins (such as alpha-smooth muscle actin (SMA)) in Notch-transformed endothelial cells. Moreover, we show that endothelial cells expressing activated Notch undergo a functional change characteristic of mesenchymal cells, in that they are capable of migrating towards platelet-derived growth factor (PDGF), but are no longer chemotactic towards vascular endothelial growth factor (VEGF). Our studies also reveal that the Notch-induced endothelial-to-mesenchymal transformation is cell autonomous, and independent of transforming growth factor (TGF)P signalling, which is an important regulator of this transformation in vivo. Furthermore, JAG1 stimulation of endothelial cells induces a similar mesenchymal transformation. Finally, we show that JAG1, Notch 1 and Notch4 are expressed in the ventricular outflow tract at the commencement of endocardial cushion formation. This is the first direct evidence that JAG 1-Notch interactions induce endothelial-to-mesenchymal transformation, and our findings suggest that the cardiovascular defects seen in patients with JAG1 mutations may be due to disruption of this process.

description: Agricultural production is among the riskiest production activities. Similarly to other branches of agriculture in animal breeding the finished product is the result of complex procedures. The biological-technological procedure, the creation of the product is affected by an outstanding number of environmental factors which also cause uncertainties. In the North Great Plain Region of Hungary, sows, gilts and slaughter pigs are produced on a corporate farm. The reliable operation data of this company provide a stable basis for and estimating future costs and revenue and their distributions. Monte Carlo methods are one of the generally accepted tools for modeling risks. The significant independent variables, their ranges and probability distributions, and the correlation between them were inputs to the model. The values of the variables were produced using a random number generator. The computer simulation was performed using@Risk (Palisade Corporation) software. The study concentrates on the factors affecting the number of offspring (piglets). Model inputs were the mating, mortality and farrowing rates; the costs and the income values based on these rates have been analysed as the output data of the model.

description: We study the creep motion of an elastic string in a two dimensional pinning landscape by Langevin dynamics simulations. We find that the Velocity-Force characteristics are well described by the creep formula predicted from phenomenological scaling arguments. We analyze the creep exponent $μ$, and the roughness exponent $ζ$. Two regimes are identified: when the temperature is larger than the strength of the disorder we find $μ\approx 1/4$ and $ζ\approx 2/3$, in agreement with the quasi-equilibrium-nucleation picture of creep motion; on the contrary, lowering enough the temperature, the values of $μ$ and $ζ$ increase showing a strong violation of the latter picture.

description: Supergiant fast X-ray transients (SFXTs) are a sub-class of supergiant high mass X-ray binaries hosting a neutron star accreting from the stellar wind of a massive OB companion. Compared to the classical systems, SFXTs display a pronounced variability in X-rays that has long been (at least partly) ascribed to the presence of clumps in the stellar wind. We report here on the first set of results of an on-going XMM-Newton observational program aimed at searching for spectroscopic variability during the X-ray flares and outbursts of the SFXTs. The goal of the paper is to present the observational program and show that the obtained results are according to expectations, with a number of flares (between one and four) generally observed per source and per observation (20~ks-long, on average). We base our work on a systematic and uniform analysis method optimized to consistently search for spectral signatures of a variable absorption column density, as well as other parameters of the spectral continuum. Our preliminary results show that the program is successful and the outcomes of the analysis support previous findings that most of the X-ray flares seem associated to the presence of a massive structure approaching and getting accreted by the compact object. However, we cannot rule out that other mechanisms are at work together with clumps to enhance the X-ray variability of SFXTs. This is expected according to current theoretical models. The success of these observations shows that our observational program can be a powerful instrument to deepen our understanding of the X-ray variability in SFXTs. Further observations will help us in achieving a statistically robust sample. This is required to conduct, in the future, a systematic analysis on the whole SFXT class with the ultimate goal of disentangling the role of different mechanisms giving rise to these events.

Rural development is of great significance for the future of both the EU and Hungary. We must reduce migration, create new jobs and focus on sustainability and the principles and goals of environmental protection and nature conservation. Rural economy is a complex and dynamic system, and agriculture should be treated as a part of it. The development of rural settlements and their infrastructure, the manifold exploitation of the agroecological potential, the rationalization of farming remain, extremely important components of rural development.

description: BACKGROUND: There is resurgent interest in the concept and practice of self-care as a means to improve the health, wellness and wellbeing of individuals, and as an avenue to mitigate financial pressures and growing demands on health and social care systems worldwide. An ongoing challenge has been the lack of clarity on the specific nature and entire scope of self-care, coupled to a lack of a universal or widely accepted framework that could support the conceptualisation and study of selfcare in its totality, in all settings and from different perspectives. OBJECTIVES: To advance a comprehensive yet pragmatic and widely accessible framework to support the conceptualisation of self-care in its totality, in order to facilitate the development, commissioning, evaluation and study of self-care initiatives across a variety of settings. METHOD AND FRAMEWORK DEVELOPMENT: A pragmatic review of the academic and lay literature was undertaken to identify extant theories and conceptual models of self-care. Following a content analysis, the models were characterised, and a configuration matrix was constructed to illustrate the key components and main themes of each model. These themes were organised into a number of domains which were grouped together into cardinal dimensions of self-care. The dimensions of self-care were consolidated in an inclusive framework and visually depicted on a schema to illustrate their inter-relationship. RESULTS: We identified a total of 32 candidate models, theories and frameworks of self-care. Characterising these models led to the identification of various themes and domains. These were found to naturally group into four cardinal dimensions of self-care: (1) Activities, (2) Behaviours, (3) Context, and (4) Environment. A new model was synthesised to illustrate the relationship between each dimension on a configuration matrix resulting in the creation of the Self-Care Matrix (SCM). CONCLUSION: The Self-Care Matrix (SCM) is a useful framework that can be used to conceptualise and frame the totality of self-care and its various interlinked elements. SCM is intended for use by all stakeholders who are interested in the study, development, commissioning and evaluation of self-care initiatives.

description: Sustainability and multifunctionality, two key principles, which will determine future development in any activities. On the bases of these principles, society as a whole has already outlined future expectations towards rural areas. Rural functions (economic, ecological and socio-cultural ones) have been declared in European Charter for Rural Areas. To what extend can different rural development initiatives meet these functions? The question may be answered by using the method of multifunctional rural resource analysis (NAGY, 2007). The paper is investigating the potential for Hungarian grasslands by using this methodology. It is concluded that our grasslands, as land use systems in their present conditions can participate in integrated rural development in the most balanced way compared to other land use systems in the county. Economically their potential is good. Ecologically their potential is outstanding. The socio-cultural potential of grassland use in Hungary is also outstanding due to the historical roots. As a future prediction the relative importance of the three grassland functions has been outlined in integrated agriculture and rural development.

description: The $120^0$ ordered antiferromagnetic state of the Hubbard model on a triangular lattice presents an interesting case of $U$-controlled competing interactions and frustration. The spin stiffness is found to vanish at $U^* _{\rm stiff} \approx 6$ and the spin-wave energy $ω_M$ at ${\bf q}_M=(2π/3,0)$ etc. is found to vanish at $U_M ^* \approx 6.8$ due to competing spin couplings generated at finite $U$. The loss of magnetic order due to the magnetic instability at ${\bf q}_M$ yields a first-order quantum phase transition in the insulating state at $U=U_{\rm M}^*$. Implications of the quantum spin disordered insulator to the spin-liquid state and Mott transition in the organic systems $\rm κ-(BEDT-TTF)_2 X$ are discussed. Effects of hole and electron doping on magnetic ordering and spin stiffness are also examined.

description: The purpose of this paper is to evaluate the marketing management capabilities of SMEs producing traditional food products, in order to analyse the market orientation of SMEs in the food industry. Following the theoretical approach of Market Orientation, our analysis is based on an assessment of the marketing management process. The methodology refers to a survey developed through a questionnaire published on the web, and a sample of 371 firms based in Belgium, Italy, Spain, the Czech Republic and Hungary was used in the analysis. Cluster analysis was applied to find the different levels of market orientation of the firms. The results revealed a certain lack of appropriate skills in marketing management in the firms of the sample, confirming the evidence found in economic literature concerning SMEs. Nevertheless, cluster analysis outlined a group of firms with good marketing capabilities and market oriented, and these represent a great part of the sample (40%). With regard to the stages of the marketing management process, the most problematic are those of planning and implementation, and control and evaluation, highlighting the difficulties SMEs encounter in carrying out coordinated marketing; which appears to be generally characterised by poor organisational capacity.

description: The general objective of this paper is to present the inner connections of the broiler product chain and the process of value generation in the economic situation of 2007. I introduce the input-output model of the broiler product chain adapted from macro-economic analysis, in which I calculated the direct connections of the product chain phases and between the national economic branches outside the chain. Then I point to the disproportion of the product chain through the profit distribution. Moreover, to evaluate the process of the value generation I demonstrate the value added generated along the value chain (year 2007). On the basis of the results 825 EUR of value added is realized to one ton of ready product (chicken meat), from which the major portion is shared by processing. The paper also determines the added value and the major factors influencing its ratio within the product chain.

description: Eastern part of Croatia is agricultural region according to natural resources (fertile soil, first of all), as well as human potential (long experience in traditional agriculture). Besides agriculture as traditional activity, a characteristic of rurality is also added to this region. Rural area is dominant in Eastern Croatia and it effects on relatively small urban areas. This paper represents new possibilities of rural economic activities on family farms in Eastern Croatia. Role and significant of rural economic activities is analyzed through indicators overview (land structure, GDP, population, population density, TEA index, unemployment ect.). Challenges through diversification of rural economic activities in this paper includes added economic activities realized on family farms through tourism, crafts, handy work, processing, renewable energy etc. Added economic activities on family farms in Eastern Croatia participate with only 3.9%. Suggestions and possibilities measures of rural economic activities diversification are reflected through two main streams. First stream is diversification of activities through added value of agricultural products as vertical connection (organic food, autochthony products, functional food, renewable energy sources etc.). Other one economic activity diversification indicates distribution function of final products through different services on the family farm (direct sale, specialized shops, rural tourism and many other services).

description: We study a semi-local Abelian Higgs sigma model with $\mathbb{CP}^2$-valued scalar fields coupled to gravity. We establish the conditions needed for self-duality in this system and obtain cosmic strings, both of self-dual character and out of the self-dual point, in the reference chart of $\mathbb{CP}^2$. In any of the other two charts of a minimum atlas, the transition functions break the global $SU(2)$ symmetry to the Abelian subgroup $e^{i σ^3 α}$. In this context, using the transition functions a new self-dual structure can be constructed, which defines a second species of cosmic strings. Because of the presence of a potential energy for the scalar fields, each species takes values in a different bounded region of the target space and is most naturally described using a particular chart of $\mathbb{CP}^2$.

description: Central authorities are the prominent choice when two parties wantto establish trust between each other. For example, web servers are usingcentral authorities to establish a secure socket layer (SSL) connection withthe browser. A signi?cant aw of central authorities is that, if the primarynode is compromised, all of the nodes are rendered untrustworthy, becauseof the hierarchical structure. Another alternative to central authorities isthe Pretty Good Privacy (PGP) web of trust (WOT), where each user actsas an authority. Still, a lack of incentives for correctly identifying anotheruser as trustworthy and missing punishments for malicious actions are themain reasons why the WOT is not considered reliable. Additionally, sybilnodes represent a threat to the WOT since there is no defence mechanismfor identifying a group of users who maliciously identify each other astrustworthy.Multi-factor authentication (MFA) is the concept that emerged in the1980s. However, most of the customers did not consent physically carryinganother factor for authentication and thus, the market did not adoptit. After introducing smartphones that provide the possibility to sendevidence of possession, inherence, knowledge, or context to another user,MFA is accessible for billions of people. MFA is used as a safer wayto establish trust relations in a network. Security-critical organizationssimilar to banks, authenticate customers using their knowledge, inherence,and possesions. Furthermore, contextual information such as the time,location, and device model can be considered as an additional factor ofauthentication. The more factors are used during authentication, the saferthe process becomes. Thus, if the attacker compromises one factor, it isnot valuable for the authentication without other factors because until allof the factors are not validated, the user cannot be authenticated.In this thesis, another alternative to public key infrastructures calledAuthcoin, is further developed using customizable challenges and MFA.Blockchain technology is utilized for storing authentication-related data,and hence, transparency, trustworthiness, and immutability of data areachieved. This thesis implements an additional layer of security for theAuthcoin protocol by providing an MFA artifact and describing how toreplace central authority and PGP/WOT systems by the implementedsolution. The produced software artifact is documented and described fortechnical-oriented and managerial-oriented readers.
On the size of the algebraic difference of two random Cantor sets

description: In this paper we consider some families of random Cantor sets on the line and investigate the question whether the condition that the sum of Hausdorff dimension is larger than one implies the existence of interior points in the difference set of two independent copies. We prove that this is the case for the so called Mandelbrot percolation. On the other hand the same is not always true if we apply a slightly more general construction of random Cantor sets. We also present a complete solution for the deterministic case.

John Weinzweig’s Woodwind quartet : a study in compositional development and serial methods
Creators: name: Lind, Stephanie Kathleen
Publisher: name: University of British Columbia
Year: 2009

description: John Weinzweig was the first Canadian composer to use techniques of serial organization in his compositions. Through his teaching, composing, and promotion of Canadian music, he has been influential in the development of Canadian music. Because of this, it is of interest to study one of his significant works, the Woodwind Quintet (1963/64). This work exemplifies Weinzweig's serial techniques, including the use of row forms that share common segments (such as dyads, trichords, tetrachords, and hexachords), as well as an allusion to octatonic sounds. This thesis approaches Weinweig's work first from a serial standpoint, and then examines how the composer approaches the idea of motivic development within his work. Thorough analysis of twelve-tone relationships, themes, textures, and rhythms reveals how Weinzweig focuses not just on serial materials, but also on other aspects of composition. Following a brief introduction about the composer and the piece, Chapter 1 examines the properties of the row used in the Woodwind Quintet. The discussion continues, in Chapters 2, 3, and 4, by examining each movement from a different analytical perspective, giving an overview of the work as a whole. Texture and instrumentation are the focus of the discussion of the first movement; segmentation is examined in the second movement; and rhythmic motives are studied in the third movement. Rotation, inversion, and other serial techniques are examined in the work as a whole. This thesis attempts to give an overview of Weinzweig's compositional style while discussing specific passages from the Woodwind Quintet and their unique manner of development.

description: The moral value is significant for everyone in every sphere of human life. Moral lessons should be properly taught among students in Schools, Colleges, Universities, Vocational training centers, Madrasas and so on. Above all, along with parents or guardians, it is the prime duty and responsibility of the educator to impart moral based values in order to develop moral qualities such as humility, integrity, truthfulness, courtesy, tolerance, sacrifice, mutual compromise etc among the youth and all level pupils. It will assist in developing positive, constructive social attitudes in new generation which prompt them to raise their moral voice against social evils. The harmonious coexistence of diverse ideologies in society requires respect for ethical and moral values. Value addition from moral education inculcates these virtues in a systematic and widely acceptable manner. Morality is basically the knowledge of knowing what is right and what is wrong. With the morality human being can preserve their sense of humanity and empathy for others’ sorrows while at the same time people can retain their sense of unselfishness for others. Here in this research paper, the “Universal Education Theory” is explained and elaborated which innovated on 2019 A.D. by Dr. Rejaul Abedin, PhD, FCMAN. The innovator who strongly believes that in the present world Universal Education Theory will be useful as it will redirect to gain moral education or to train individual through morally during their academic, social and unearthly life. Moreover, Moral education can control human mind to prevent corruption, manipulation at both the micro and macro levels.Keywords : Universal Education Theory, Moral Education, Universal Education Formula, Prevention of corruption, UE formula,

description: We experimentally demonstrate a dipolar polariton based electric field sensor. We tune and optimize the sensitivity of the sensor by varying the dipole moment of polaritons. We show polariton interactions play an important role in determining the conditions for optimal electric field sensing, and achieve a sensitivity of 0.12 V-m$^{-1}$-Hz$^{-0.5}$. Finally we apply the sensor to illustrate that excitation of polaritons modify the electric field in a spatial region much larger than the optical excitation spot.
