Improving the Methods of Assessing the Socio-Economic Potential of the Regions of the Republic of Uzbekistan on the Basis of Intellectual Mathematical Models
Authors:   PhD, Tashkent State University of Economics, Otajanov Umid Abdullaevich
Published: December 2021

The article examines the investment potential of the territories of the Republic of Uzbekistan and the issues and investment distribution problems in them. Also, in the article predictions were made using programs of mathematical models of artificial neural networks in the analysis of distributions process problems,and the results were determined by comparing the results with trend and panel methods. Sustainable territorial socio-economic development is determined by general laws of country socio-economic development, the share of export products in the total output of the region, depending on the composition of the gross regional product, in key sectors of the economy is determined by features such as competitive product, scientific potential, population income. Therefore, the problems that arise in ensuring the socio-economic development of the region in modern conditions will have their own regional characteristics.Addressing the territorial socio-economic development problems require strengthening the regulatory role of the state in determining regional economic policy, governance, the development of effective systems, tools and methods of state regulation. Sustainable territorial socio-economic development also depends on the self-sufficiency level of resources and effective budget finance, credit, tax and price policies.
Evaluating English Textbook: A Sociolinguistic Perspective
Authors: ÇAKIR Nurcan
Published: December 2021

This paper examines an English textbook used in Turkey within the context of sociolinguistic issues. Various studies on book evaluation can be found in the literature; however, there seems to be very limited research analysing the course books from a sociolinguistic perspective. By employing the qualitative research design, the 3rd grade English book Just Fun English (Tiras, 2019) published for public primary schools was analysed using the Sociolinguistic Textbook Evaluation Rubric (Atar & Erdem, 2020). Within the framework of the six criteria of the rubric, the results indicate that the textbook is hardly in conformity with the sociolinguistic matters. Though the textbook considers the linguistic ecology of learners and makes learning English accessible to the public, there are no examples of non-native and non-standard accents of English, non-native-non-native interaction, and successful bilinguals. This study contributes to a growing body of literature by evaluating a textbook concerning the sociolinguistic issues and it offers some insights into the improvement of the textbook.
Role of Patrapinda Sweda and Matrabasti in management of Katishoola (Low back pain)- A case study
Authors: Mishra Rajkumar , Sengupta Sanjukta , Mund Jayshankar
Published: December 2021

Low back pain (LBP) is the most common chronic musculoskeletal disorder. It has symptoms like pain, swelling, stiffness or limited range of motion and these symptoms lie very close to the entity Katigraha&Katishoola in Ayurveda which is coming under Vatavyadhi(diseases of Nervous system and musculoskeletal system). The Contemporary management has little effect on the disease.   It is an important clinical, social, economic and public health problem affecting the population indiscriminately.  It is a disorder with many possible aetiologies, occurring in many groups of the population, and with many definitions. The prevalence of LBP in Indian population has been found to vary between 6.2% (in general population) to 92% (in construction workers). This problem supposedly has a favourable natural history, although it can markedly disable, and has challenged the health care providers. Understanding the role of different medical systems in the management of backache,it is important for the cost-effective management of the disease. Ayurveda treatment modality, exercise, regimen may result in low backache recovery. Here in this article, the diagnostic and treatment aspects are discussed and applied critically using Ayurvedic therapy.

Secondary education in transition in Nigeria: The question of quality
Authors: Alani R. A.
Published: December 2021

The paper traced the history of the development of secondary education in Nigeria since its inception in J859. The paper noted the emphasis on traditional art and science subjects in the past and the innovations that have been brought into the secondary school curricula by the National Policy 011 Education published in 1977, but revised in J981 and J998. The problems of implementing the curricula were briefly mentioned. The paper finally highlighted steps that could be taken to improve the quality of secondary education, such as provision of physical and material resources, adequate financing of education, teacher training and development, improvement of the conditions of service for teachers and supervision of instruction, among others.
Work-home conflict among female teachers in basic educational institution in the Cape Coast municipality of Ghana
Authors: Agezo Clement K. , Dzinyela Joseph M
Published: December 2021

One of the factors that contributes most significantly to the success of an organization is the effectiveness of its staff. This is particularly true of educational institutions. No matter how efficient and well-intentioned the school administrator is, he can hardly achieve success without the support and co-operation of well qualified, didicated, committed and effective staff. The study cirtically examines work home conflict among female teachers at the Basic Eduwtion level. and its impact on effectiveness in the classroom and other organizational work in the school. Data from questionnaires and interviews with 268 female teachers and 25 heads respectively suggest that there is a relationship between work-home conflict and effectiveness of female teachers. The combination of paid employment with the care of the home and children involves an excessive strain and stress which negatively affects effectiveness of female.
Employing management by objectives in multi-campus administration of a tertiary institution, how feasible?
Authors: Okae-Anti Christie
Published: December 2021

Educational managers in tertiary institutions operate basically in four areas: to maximise results, by harmonising immediate and longrange goals; to establish precise goals and measurable objectives; and to evaluate progress toward pre-determined goals and objectives, to organise, motivate, communicate and sh-engthen superordinates, peers and subordinates. In employing MBO the registrar and others in his department would define the major areas of their responsibilities and establish measures for operation. For instance, in the major areas. Thus the three satellite campuses of the University College of Education, Winneba, operating under a common mission may visibly embrace the principle of MBO, for after all, the large number 163 of disciplines and the interrelationship through the division system put the university in a better position to assemble the necessary skills and expertise to attain the mission and visions of a young multi-campus university.
Improving the use of Competence-Based Training (CBT) in polytechnic education in Ghana: an evaluation of the civil engineering department of Takoradi Polytechnic
Authors: Apori Samuel Obeng , Nkrumah Maame Afua
Published: December 2021

Quality Polytechnic education and training is expected to equip students with consistent, high quality Training and education that can be delivered and recognized across territorial boundaries. Currently, the ongoing restructuring of the labour markets and significant changes in occupational structures and skill requirements have strongly challenged the quality and performance of vocational education in Chana. Further, substantial concern is being raised about how polytechnic education can influence employment and the school to work transition. This research explores these new changes and demands. A major objective of the study was to investigate how the department could improve the effectiveness of the already existing mechanisms for CBT at Takoradi Polytechnic and maximize the effectiveness of Polytechnic-industry collaborations. There were in total 181 respondents; from the industries and Takoradi Polytechnic. Three different sets of questionnaires and an interview guide were used to collect data the respondents. Descriptive statistics were used to present the data after which evaluation criteria were used to make value judgment about the quality of the polytechnic education. The study showed that the level of practiced Training is not satisfactory, and there is a limited relationship between the polytechnic and the industry. Hence there is the need to: redesign the curriculum giving more attention to practical training; improve the practical knowledge of the staff; make real life research a core activity of the department; and develop other better ways of connecting the polytechnic with the industries other than students' attachment using the CBT approach.

Authors: Oguntiemehun Yekinni Abiodun
Published: December 2021

This study assessed the adequacy or otherwise of the reading materials (modules) and objectives achievement of the National Teachers' Institute's Nigeria Certificate in Education programme in Ogun State. To obtain an in-depth assessment, subject specialists (experts) were randomly drawn from the three tertiary institutions that train teachers, namelv Olabisi Onabanjo University; Ago-Iwove, Tai Solarin Unil'ersity of Education, Ijagun Ijebu-Ode, and Federal College of Education, Osiele, Abeokuta. In all, sixty-three (63) subject specialists were sampled for the modules' assessment. The records on graduating students of National Teachers' Institute were collected from the State Headquarters, Abeokuta to assess the objectives achievement. Data were analyzed using descriptive statistics. Results showed that the objectives are being achieved; the modules are adequate in terms of content, presentation, self-evaluation, dynamism and editing, but not adequate in printing and availability. It is therefore recommended that the NTI(NCE) programme should not be scrapped; quality printing materials for the modules should be used and be readily available.
La independencia judicial y su endémico déficit de garantías
Authors: Andrés Ibáñez Perfecto
Published: December 2021

La independencia judicial es un valor a cuyo dilatado proceso de formación histórica han contribuido la experiencia práctica y la elaboración teórica, siempre en estrecha conflictual relación. En este trabajo se deja breve constancia de ese proceso, contemplando ambas vertientes del asunto. Luego se examina críticamente el modelo napoleónico de organización judicial, un verdadero hito, extraordinariamente difundido y particularmente negativo desde el punto de vista del principio que se considera, que además ha dejado su impronta en todas las organizaciones judiciales de procedencia europea continental. Se presta atención al dato sumamente significativo de la fácil integración funcional de los jueces de ese perfil en la experiencia europea de los nazifascismos y en otras dictaduras. Se discurre sobre las exigencias que el vigente constitucionalismo de derechos suscita en materia de modelo de juez y de estatuto judicial. Y, en fin, se pone el foco en la desoladora experiencia española del Consejo General del Poder Judicial.
Effects of dietary inclusion of Spirulina meal on growth and hematological parameters of cultured Asian sea bass, Lates calcarifer
Authors: Tan Chin Yong , Galaz German Bueno , Shapawi Rossita
Published: December 2021

This study was conducted to investigate the effects of dietary inclusion of Spirulina platensis on growth performance and hematological parameters of juvenile Asian sea bass (Lates calcarifer) reared in a freshwater culture system. Five experimental diets were prepared by replacing fish meal protein with the microalga at replacement levels of 5% (SP5), 10% (SP10), 20% (SP20) and 30% (SP30), and the substitution effect was compared with a control diet (Con) in which fish meal was the sole protein. Fish were stocked in net cages placed in a 150-ton tank with a stocking density of 20 fish per cage. After 8 weeks of feeding trial, the fish did not show any significant differences in growth performance but numerically higher weight gain and specific growth rate were achieved in the fish stock fed diet SP10 compared to other treatments. Feed conversion ratio and survival rate of fish were significantly affected by the inclusion of Spirulina in the diets. Except for crude ash content, whole-body proximate composition of the experimental fish was also significantly influenced by the diets. Regarding the effects of diets on blood parameters, only hematocrit, hemaglobin, HDL-c and AST were significantly affected by the inclusion of Spirulina in the diets. This study demonstrated that Spirulina could replace up to 10% of FM protein in practical diets of juvenile Asian sea bass without negative effects on growth performance. However, replacement of fish meal with Spirulina meal at 5% might be considered for commercial use considering a significant decrease in survival above this value.
Dietary leucine requirement for growth and maintenance, and its utilization efficiency for fingerling of Nile tilapia, Oreochromis niloticus (Linnaeus)
Authors: Zehra Seemab , Khan Mukhtar A.
Published: December 2021

Two separate 12-week feeding trials were conducted to investigate the leucine requirement for maintenance and its utilization efficiency for growth of fingerlings of Oreochromis niloticus. In the first experiment, six diets (35% CP; 13.71 kJ g-1 DE) containing graded levels of leucine (0.71, 0.95, 1.26, 1.49, 1.72 and 1.95% dry diet) were fed to the fish (3.74Â±0.11 cm, 0.65Â±0.05 g) near to satiation to determine its leucine requirement. Highest performance in terms of absolute weight gain (AWG, 5.83 g fish-1), protein gain (PG, 1.02 g fish-1), leucine gain (LG, 82.19 mg fish-1), RNA/DNA ratio (4.74) and best feed conversion ratio (FCR, 1.51) were recorded at 1.49% dietary leucine. Quadratic analysis of AWG, PG, LG against varying levels of leucine indicated the requirement at 1.56, 1.61 and 1.57% dry diet, corresponding to 4.45, 4.60 and 4.48% dietary protein, respectively. In the second experiment, six experimental diets (35.0% CP; 13.8 kJg-1 DE) at 5, 25, 45, 65, 85 and 95% of optimum level of leucine determined in experiment I (1.58% dry diet) corresponding to 0.08, 0.39, 0.71, 1.03, 1.34 and 1.50 g of leucine 100g-1 of dry diet were given to the same sized fish under almost identical laboratory conditions to estimate the leucine maintenance requirement and its utilization efficiency which were calculated by solving the linear equations of protein gain and leucine gain data to leucine intake levels. The maintenance requirement based on protein gain and leucine gain calculated at Y = 0 amounted to 8.23 and 9.62 mg kg-1 BW 0.7day-1. Extrapolating the linear equations of protein gain and leucine gain to the Y intercept showed that zero leucine intake resulted in a net daily loss of 91.9 mg whole body protein and 5.65 mg whole body leucine kg-1 BW0.7. The maintenance need for leucine represented 6Â·07% of the total need for leucine. Slope of the leucine gain line showed that the efficiency of leucine utilization above the maintenance level is 58.7%.
Determination of selected metallic elements in marsh clam, Polymesoda expansa, collected from Tanjung Lumpur Mangrove Forest, Kuantan, Pahang
Authors: Ong Meng Chuan , Ibrahim Amalina
Published: December 2021

Presence of metallic elements in organisms is one of the important topics in environmental pollution, toxicology and food safety. It has been extensively studied because of the impact of these elements on the ecosystem and health of the seafood consumers. This study provides information on the concentration of some essential metals (copper, Cu; zinc, Zn) and non-essential metals (cadmium, Cd; lead, Pb) in the commonly consumed marsh clam, Polymesoda expansa, sampled randomly from Tanjung Lumpur mangrove forest, Kuantan, Pahang. It also focuses on the human health risk assessment in terms of toxicity of these metallic elements. Closed acid digestion method was used to digest the samples and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) was used to measure the metal contents in the samples. The mean concentration of each metal in the tissues was recorded on a dry weight basis. The average values were: Cu, 15.5 Î¼g/g.; Zn, 296 Î¼g/g ; Pb, 2.31 Î¼g/g and Cd, 1.04 Î¼g/g . These values are within the permissible limits set by Malaysian Food Regulation (1985) and the World Health Organization (1982). The pollution load index (PLI) value of 2.94 indicates that there is no serious metal pollution in this study area. The correlation coefficient matrix between four metallic elements shows positive value, suggesting that the selected metals may have originated from the same source and accumulated in the clam tissue. A positive correlation was noted between the size of the clam and concentrations of Cd, Zn and Cu whereas it was negative for Pb. The present finding shows that the marsh clams from Tanjung Lumpur are safe for human consumption. However, a proper and continuous assessment should be done in order to monitor any changes in the contents of metallic elements since Tanjung Lumpur is near the Kuantan city center and the mining activities at the upstream area might at some stage cause metal pollution.
Pond sludge and increased pH cause early mortality syndrome/acute hepatopancreatic necrosis disease (EMS/AHPND) in cultured white shrimp
Authors: Akazawa Noriaki , Eguchi Mitsuru
Published: December 2021

Microcosm experiments simulating the occurrence of early mortality syndrome/acute hepatopancreatic necrosis disease (EMS/AHPND) in white shrimp production ponds were performed in 30-L aquariums. Healthy white shrimp, Litopenaeus vannamei, were reared in aquariums containing EMS/AHPND-free hatchery or pond water. Raw pond sludge, collected from shrimp ponds where EMS/AHPND had occurred, was added to some test aquariums, while others were treated with sterilized pond sludge. In some aquariums, water pH was increased from 7.5 to 8.8. Microcosms with stable pH (around 7.5) and/or autoclaved sludge served as controls. The combination of raw sludge and increased pH induced EMS/AHPND and killed white shrimp, whereas raw sludge/stable pH and autoclaved sludge/increased pH combinations did not affect healthy shrimp. Thus, EMS/AHPND outbreaks are due not only to the causative agent but also to environmental stresses such as pH fluctuation. These findings contribute to improved management in shrimp production farms.

MANIPULAÇÕES POST-MORTEM DO CORPO HUMANO: Implicações Arqueológicas e Antropológicas
Authors: Kerner Jennifer
Published: December 2021

Este trabalho é uma exploração das diferentes estratégias desenvolvidas pelas pessoas para responder ao problema do luto através das ações realizadas no cadáver. A manipulação post-mortem dos corpos regularmente fornece ao arqueólogo "sepulturas secundárias" e ossos "perturbados". Estas duas categorias são referidas com o termo genérico de “ossos na posição secundária” para expressar que os ossos não estão mais conectados e que a posição original do corpo não é mais legível. Estes depósitos são frequentemente subavaliados pelos arqueólogos porque são pouco compreendidos. Tais vestígios implicam uma gestão complexa e planejada do processo fúnebre e gestos / práticas / cerimônias em vários episódios. Eles são, portanto, valiosos para a compreensão de fenômenos sociais e crenças antigas. Esta tese propõe um esclarecimento dos conceitos relativos aos “ossos na posição secundária”, bem como um aprimoramento da metodologia relacionada a esses depósitos específicos.POST-MORTEM MANIPULATIONS OF THE HUMAN BODY: Archaeological and Anthropological ImplicationsABSTRACTHuman remains resulting from sophisticated mortuary treatments represent a preferred information source about the organization of societies and about belief systems of ancient people. Secondary deposits, sacred artefacts made of humain bones or dismembered / scattered burials emerge as precious raw material in order to reconstruct gestures, practices and, finally, the symbolic discourse built around those dead who are selected to become particular protective entities, perhaps Ancestors. An ethnoarcheological study on multiplesteps funerals has been performed in order to improve methods of recognition of these peculiar remains on the archaeological field.Keywords: Ethnoarchaeology; multiple-steps funerals; archaeological methods.

The relative effectiveness of combined spinal manipulative therapy and action potential therapy versus combined spinal manipulative therapy and placebo action potential therapy in the treatment of mechanical low back pain
Authors:   , Atkinson Micah Justin
Published: December 2021

Lower back pain represents as a common disorder, with between 60% and 80% of the general population being affected (Kirkaldy-Willis 1992:2). This, apart from just the health aspects, has serious financial implications which are an ongoing concern to industry (Frymoyer 1991: 137). This study was designed to determine the effectiveness of combined spinal manipulation and "Action Potential" therapy versus spinal manipulative therapy and placebo "Action Potential" therapy in the treatment of mechanical lower back pain. It is currently accepted that spinal manipulation is of great benefit in the treatment of lower back pain (Di Fabio 1992), and it appears that "Action Potential Simulation" therapy, a new low-frequency electrical current therapy, would fit the criteria necessary to address the dysfunctional phase of low back pain as set out by the authors such as Kirkaldy- Willis (1988).

Security issues of a system are factors that need to be considered in the operation of information systems, which are intended to prevent threats to the system and detect and correct any damage to the system. Distributed Denial of Services (DDOS) is a form of attack carried out by someone, individuals or groups to damage data that can be attacked through a server or malware in the form of packages that damage the network system used. Security is a mandatory thing in a network to avoid damage to the data system or loss of data from bad people or heckers. Packages sent in the form of malware that attacks, causing bandwidth hit continuously. Network security is a factor that must be maintained and considered in an information system. Ddos forms are Ping of Death, flooding, Remote controled attack, UDP flood, and Smurf Attack. The goal is to use DDOS to protect or prevent system threats and improve damaged systems. Computer network security is very important in maintaining the security of data in the form of small data or large data used by the user.

Puzzle game is a game that shifts numbers from a box consisting of nine boxes. Eight boxes must have values arranged in numerical order starting from numbers 1 to 8. Puzzle games can produce the correct sequence according to the initial state provided that they follow the rules established rules. Completion of this game using a heuristic method, using the Ascent hill Climbing algorithm. The working process of the Ascent hill Climbing method is a process of looking for several possible solutions in order to get the optimal value for solving the problem by arranging the values from the position of the smallest value to the position of the largest value. The problem that is often experienced in this case is a lack of user knowledge in the concept of puzzle game rules so that search results are difficult to find,with this method it can make it easier to solve puzzle game cases by following the game rules and done systematically so that Goals are quickly found. The Goal results obtained are in the form of steps in the process of finding a solution and calculating the time required in the search to find a solution.

Public transportation is one of the important modes of transportation and is the backbone of transportation in Indonesia. The development of public transportation is also supported by the government, this government support is evident in the national policy, namely the National Medium Term Development Plan (RPJMN). Although public transportation is an effective mode of transportation, it also has obstacles in its development, namely how to meet customer desires in choosing a mode of transportation. There are several variables that are the focus of this research, namely age, gender, income, cost, speed, comfort, safety, efficiency and flexibility. The search for influential variables will use the K-Means and DBSCAN clustering algorithms, these two algorithms are also compared to their performance to find a better algorithm. The results of the Silhouette Coefficient show that DBSCAN has a better performance with a value of 0.99 than K-Means with a value of 0.86. The variables that affect the interest in using public transportation are the most important ones related to cost, speed, comfort, safety, efficiency and flexibility.

Abstract. Lidar observations were analysed to characterize atmospheric pollen at four EARLINET (European Aerosol Research Lidar Network) stations (Hohenpeißenberg, Germany; Kuopio, Finland, Leipzig, Germany; and Warsaw, Poland) during the ACTRIS-COVID-19 campaign in May 2020. The re-analysis lidar data products, after the centralized and automatic data processing with the Single Calculus Chain (SCC), were used in this study, focusing on particle backscatter coefficients at 355 nm and 532 nm, and particle linear depolarization ratios (PDRs) at 532 nm. A novel method for the characterization of the pure pollen depolarization ratio was presented, based on the non-linear least square regression fitting using lidar-derived backscatter-related Ångström exponents (BAEs) and PDRs. Under the assumption that the BAE between 355 and 532 nm should be zero (± 0.5) for pure pollen, the pollen depolarization ratios were estimated: for Kuopio and Warsaw stations, the pollen depolarization ratios at 532 nm were of 0.24 (0.19–0.28) during the birch dominant pollen periods; whereas for Hohenpeiβenberg and Leipzig stations, the pollen depolarization ratios of 0.21 (0.15–0.27) and 0.20 (0.15–0.25) were observed for periods of mixture of birch and grass pollen. The method was also applied for the aerosol classification, using two case examples from the campaign periods: the different pollen types (or pollen mixtures) were identified at Warsaw station, and dust and pollen were classified at Hohenpeißenberg station.

Abstract. The impact of anthropogenic climate change on marine net primary production (NPP) is a reason for concern because changing NPP will have widespread consequences for marine ecosystems and their associated services. Projections by the current generation of Earth System Models have suggested decreases in global NPP in response to future climate change, albeit with very large uncertainties. Here, we make use of two versions of the Institut Pierre Simon Laplace Climate Model (IPSL-CM) that simulate divergent NPP responses to similar high-emission scenarios in the 21st century and identify nitrogen fixation as the main driver of these divergent NPP responses. Differences in the way N-fixation is parameterized in the marine biogeochemical component PISCES of the IPSL-CMs lead to N-fixation rates that are either stable or double over the course of the 21st century, resulting in decreasing or increasing global NPP, respectively. An evaluation of these 2 model versions does not help constrain future NPP projection uncertainties. However, the use of a more comprehensive version of PISCES, with variable nitrogen-to-phosphorus ratios as well as a revised parameterization of the temperature sensitivity of N-fixation, suggests only moderate changes of global-averaged N-fixation in the 21st century. This leads to decreasing global NPP, in line with the model-mean changes of a recent multi-model intercomparison. Lastly, despite contrasting trends in NPP, all our model versions simulate similar and significant reductions in planktonic biomass. This suggests that projected plankton biomass may be a much more robust indicator than NPP of the potential impact of anthropogenic climate change on marine ecosystems across model.

Abstract. Global tide and surge models play a major role in forecasting coastal flooding due to extreme events or climate change. The model performance is strongly affected by parameters such as bathymetry and bottom friction. In this study, we propose a method that estimates bathymetry globally and the bottom friction coefficient in the shallow waters for a Global Tide and Surge Model (GTSMv4.1). However, the estimation effect is limited by the scarcity of available tide gauges. We propose to complement sparse tide gauges with tide time-series generated using FES2014. The FES2014 dataset outperforms GTSM in most areas and is used as observations for the deep ocean and some coastal areas, such as Hudson Bay/Labrador, where tide gauges are scarce but energy dissipation is large. The experiment is performed with a computation and memory efficient iterative parameter estimation scheme applied to Global Tide and Surge Model (GTSMv4.1). Estimation results show that model performance is significantly improved for deep ocean and shallow waters, especially in the European Shelf directly using the CMEMS tide gauge data in the estimation. GTSM is also validated by comparing to tide gauges from UHSLC, CMEMS, and some Arctic stations in the year 2014.
Between Form and Molecule: Investigating the Beyond in Chris Colfer’s The Wishing Spell
Authors: Akram Zainab
Published: December 2021

Fairy tales permeate the world with a magical charm, but time has brought changes in fairy tale narration, mode, context and interpretations. Under the post structural lens, the undertaken research investigates the transformations that occur at molecular level, beyond the physical and molar corporeality among selected characters in the fairy tale, The wishing spell (2013). The focus is not the examination of changes in physical anatomic structure or form of the selected characters, rather the exploration of body’s capability and potentials of undergoing phenomenological transformations through the lens of becoming molecular by Gilles Deleuze and Felix Guattari (1987). Becoming molecular promotes the idea that instead of comprehending the whole form of an issue, a fragment or molecule needs to be comprehended as it makes it easy to understand the entire form of problem. Becoming molecular is an internal or mind attachment of the body to another entity and the attachment or link is beyond the physical form of corporal state of being. The undertaken research endeavors to map multiple occurrences of becoming molecular in the characters of Snow White and the Evil Queen, by following the thematic model of textual analysis by Miles and Huberman (2014). The findings reveal that becoming molecular is an endless process that emerges in unlimited molecular links amid two different bodies. These links illuminate profound insights by influencing thoughts and bringing changes in actions and behavior. The changes cannot be perceived through senses as in the physical world. These links do not disrupt the physical appearance of either body, rather bring changes at molecular level.
