We are very happy to announce that from 13th December 2018, Mr.Ebrahim Jamshidi has joined the team of Elixir Editorial Advisory Board. He/She will carry a special responsibility for dealing with manuscripts based on Educational Management. The appointment of Mr.Ebrahim Jamshidi as member, Editorial Advisory Board strengthens the links and will make it easier for prospective authors to establish contact with the journal.

An aqueous medium multicomponent synthesis of trans-2-aroyl-5-methyl-3-aryl-3, 5-dihydrofuro [3, 2-c]-quinolin-4(2H)-one in pyridine by conventional and microwave irradiation, easy workup, smaller reaction time and lack of column chromatography are the significant feature of this protocol. The Phenacyl bromide with pyridine is first time used as starting with1-methyl-4-hydroxy quinolone, substituted aromatic aldehydes for the biological interest compound (4a-p) for this green transformation generating one C-O and two C-C bonds in one operation, Knoevenagel followed by Michael addition and intramolecular Cyclisation.

Multidimensional assessments of groundwater quality have been carried out in some communities of the Lower Pra Basin in Ghana. Samples were collected from thirty one (31) water points. All ions were determined using standard methods. Results show that ion concentrations are primarily influenced by various hydrogeological processes such as silicate weathering, ion exchange and sea aerosol spray. From the SAR calculation, 90.3% of the water was within the excellent category; 6.5% and 3.2% were within the good and unsuitable category respectively. Calculation of % sodium showed 7%, 48%, 32% and 13% being good, permissible, doubtful and unsuitable respectively. From the Wilcox’s diagram, approximately 71% fall within excellent to good category; 26% in the category of permissible to doubtful; 3% within the doubtful to unsuitable category. Approximately 90% of the samples were found to be good by RSC index; 7% fall within the doubtful category and 3% unsuitable. A high percentage was within permissible ranges for TDS and TH. The results suggest that generally groundwater samples are suitable for domestic and irrigation purposes under normal temperature and pH condition.

The present study was made an attempt to identify the biochemical constituents such as protein, carbohydrate and amino acids in Fenneropenaeus indicus tissue and hepatopancreas. The growth rate of F. indicus was identified with three types of feed habits via., live feeds Artemia, algae (Chlorella sp.) and artificial feed (pellet) inducing the total growth rate was measured by weight biomass. The level of protein, carbohydrate and amino acids content of tissue and hepatopancreas in F. indicus were found maximum in Artemia feed. The Artemia (live feed) resulted better growth and high content of biochemical constituents of the shrimp F. indicus when compare of the other feed.

This piece of research presents an interdisciplinary and challenging research approach originated from mental stimulation and brain based learning paradigms. In more details, it specifically adopts the approach of Artificial neural networks (ANNs) which are conceptually computational systems with increasingly common and sophisticated applications. Furthermore, this work aims to present realistic design of a model integrating ANNs with brain based learning paradigm associated to some educational phenomena. Referring to recent neurological researchers findings that have revealed in order to promote and encourage maximum learning capacity within learners' brains. It is vital to enhance learning performance of arbitrary educational process via mental stimulation of brains' synapses and neurons. In practical educational environment, brain is intimately involved in and connected with, everything instructors and learners do while face to face tutoring sessions. Interestingly , the obtained modeling results support improvement of learning creativity following increase of synaptic connectivity in addition to the neurobiological research work concerned with the other half of the brain (Glial cells).

Paraneoplastic limbic encephalitis is a rare clinical entity. It is clinically manifested by neuropsychiatric disorders that accompanies or precedes most often the discovery of the cancer.We report an interesting case of paraneoplastic limbic encephalitis with anti-Ma2 antibody in a man of 51yers with only apparently benign microcalcification of the testes on imaging, and whose histopathological examination revealed a seminomatous germ cell tumor.

The present paper describes research undertaken to evaluate the appropriateness of strategic performance measurement (PM) system and processes for small- and medium-sized Indian enterprises (SMEs). An evaluation is undertaken of three case studies to facilitate a performance model for the strategic improvement. This evaluation resulted in the identification of a process, based on its congruency to the theoretical model adopted. Data collected from SMEs is analyzed. The paper concludes with a number of recommendations to facilitate the application of model for SMEs.

In this paper we produce a hypergraph using the Peterson hypergraph. We prove that two vertices in this hypergraph are adjacent if and only if they are not adjacent in the Peterson graph. We find maximum independent sets, maximum stable sets, domination number and H-domination number of this hypergraph.

In this paper, slow evaporation method was used for the synthesis of 4-aminopyridinium adipate in triclinic crystal system and it was characterized by the powder X-ray diffraction pattern. Using the X-ray broadening, the crystallite sizes and lattice strain on the peak broadening were studied by Williamson-Hall plot. The result of mean particle size showed that the particle size increases with the decrease in breadth (in degrees) with mosaic defect. Key words: 4-aminopyridine, adipic acid, Powder X-ray diffraction pattern, Williamson-Hall plot

Teaching is a time – honored process and the teacher is now trying to look for better content presentation skills in the light of recent tendencies to reach theory of teaching through practice in the field of learning. The day of teacher’s exclusive concern with presentation of knowledge on Herbartion lines to form apperceptive mass in the minds of learners has come under careful scrutiny by researchers like J.Piaget, D. Ausuble and Guilford. Now cognitive learning is being understood with greater insight and content presentation has become more thoughtful and technical. The practitioners have gone beyond the organization of concepts in the mind of the learner through presentation techniques. But that is not enough. How the learner moves from his personal concrete experience to reflective observation, abstract conceptualization and active experimentation of it in real life situation is the new constructivist schemata which compels the thoughtful teacher to travel from his ivory tower of presentation teaching to the earth rooted learner’s constructivist approach to learning.
