Aye Aye Myint, Aye Aye Khaing, Tin Tin Moe, Tu Tu Wai
In this study, the removal of lead by adsorption using charcoal of plum seed coats was conducted. The percent adsorptions of lead (II) ions on four different sizes of charcoal samples were determined. The optimum size (40 mesh) of the charcoal powder sample was observed on the basis of time duration to achieve the completeness and percent adsorption for lead ion. The FT-IR spectral measurements were done before and after adsorption of lead ion to know the efficiency of each particle size of the charcoal powder sample. The adsorption of Pb2+ on plum seed coats charcoal follows Freundlich isotherm. The straight line with value of slope equal to 1/n and log k as y-axis intercept was obtained. Lead is a highly toxic heavy metal and exposure to which can produce a wide range of adverse health effects. Adsorption is the adhesion of atoms, molecules, or ions from a gas, liquid or dissolved solid to a surface charcoal from nut shells and husks are particularly good as adsorbents. Hence, the activated charcoals are now widely used to remove pollutants from waste water by adsorption processes.

Ethiopian Paper Currency Recognition System: An Optimal Feature ExtractionPDF
Asfaw Alene Shefraw
Abstract—Forged banknotes are becoming serious threats hampering smooth transactions in Ethiopia. Hence, Availability of such fake notes in the market needs the automation system. The banking industries in Ethiopia are unable to full fill the ATM’s intensively. Nevertheless, banks have not yet utilized a reliable recognition system to identify forged banknotes. This calls for the development of a better authenticity verification system. In this study, we have examined the color momentum, SIFT, GLCM, combination of SIFT, color and GLCM, and CNN as a feature extraction technique and FFANN as a classifier to design the Ethiopian banknote recognition system. The experimental result shows that the CNN feature registers 99.4% recognition accuracy in classifying Ethiopian banknote denomination. Again, for fake currency recognition, CNN feature outperformed the other feature extraction techniques with an accuracy level of 96.46 %. Therefore, it is recommended to study the CNN model by with an advanced architecture like GoogLeNet and ResNet with a larger dataset.

Optimal Power Restoration in MV Distribution Network with Optimal Allocation of Remote Controlled SwitchesPDF
Doaa Adel Hassan Sabry
This paper presents a heuristic programming approach of optimal restoration of Medium Voltage radial distribution network. After the isolation of the faulty section, the supplying must be restored in the whole area through the network reconfiguration. A new methodology to find remote controlled switches (RCS) optimal location in a Medium Voltage (MV) distribution network is presented. This methodology is based on the minimization of Energy Not Supplied (ENS) for the whole electric system, considering the possible switches locations in every feeder. This methodology considers also the normally closed (NC) and normally open (NO) switches previously installed in the MV network. Reliability data relating to power lines are necessary. The ENS cost for each load pointand total ENS is also considered. Finally, the proposed methodology can help a system operator to evaluate the economic impact of new RCS switches in a given distribution system.
On the Interaction Between Literature and PsychologyPDF
Daniel Mengistie
Comparative literature is an interdisciplinary field whose practitioners study literature across national borders, across time periods, across languages, across genres, across boundaries between literature and the other arts (music, painting, dance, film, etc.), across disciplines (literature and psychology, philosophy, science, history, architecture, sociology, politics, etc.). Defined most broadly, comparative literature is the study of "literature without borders". Literature, which intertwines within such fields as history, philosophy, sociology, psychology and so on, is a discipline wherein language is used as a medium of expression so as to interpret man, existence and culture. The relation between psychology and literature is a bilateral relation. Human’s soul makes the literature and literature nourishes human’s soul. Human’s psychical receptions take into consideration the human and natural life perspectives and provides references of literal works; on the other hand, literature also take into account the life’s truths to make clear the perspectives of human’s soul. Literature and psychology both, pay attention to fancy, thinks, feelings sensations and soul psychical issues. Past writers and poets by detecting “unwilling conscience” psychical unwilling and reflecting many of psychical contention had found the meaning of this problem in their works. The term paper is trying to consider the relation between literature and psychology by means of psychological criticism in categories such as psychoanalysis the author, reader and text also the Psychology and the creative process, Psychoanalysis and biography by using psychoanalysis. KEYWORDS: comparative literature, literature and psychology unwilling conscious and psychological criticism.

Esther L. Baluyos, Helen L. Rivera, Genelyn R. Baluyos
School heads' leadership behavior plays a vital role in the teachers' classroom management practices. This study determined the relationship between the school heads' leadership behavior and the teachers' classroom management practices. The respondents included one hundred four (104) school heads and three hundred thirteen (313) teachers, chosen through stratified random sampling. The researcher used the Transformational Leadership Behavior Questionnaire to measure the level of Leadership Behavior of the school heads, and the Self-Assessment Classroom Management (SACM) Tool to measure the teachers' classroom management practices. The study used mean, standard deviation, and Multiple Regression Analysis as statistical tools in analyzing the data. Findings revealed that the school heads' leadership behavior and the teachers' classroom management practices were both excellent. School heads' idealized influence, inspirational motivation, and idealized attributes were the predictors of teachers' classroom management practices. School heads need to allocate time where both school heads and teachers can interact and share their beliefs, aspirations, and values in the realization's vision and mission. The annual action plan of the school, with clear outcomes and identified responsible persons, together with the steps on how each action is carried out, is suggested.

Dr Than Htike, Dr Htay Htay Myint, Dr Tu Tu Wai, Dr Aye Aye Khaing, and Htay Htay Nwe
ABSTRACT The chemical reaction usually involves organic compounds like flavonoids, alkaloids, terpenoids, polyphenols etc, reacting with metal ions to create a metal nanoparticles. The chemical constituents of plant extracts in the process act as reducing agent as well as stabilizing agent for the nanoparticles. There are a number ways of synthesizing nanoparticles; one way is using biomolecules from plant extract to reduce metal ions to nanoparticles in a single step. In this work, copper nanoparticles were synthesized by using Ecliptal alba Hassk leaves extract as bioreducing agent. Phytochemical constituents of sample leaves were detected by chemical methods and also chemical compositions of the sample were analyzed by EDXRF. Synthesized copper nanoparticles were charac-terized by FT-IR, SEM and XRD techniques.
