A. rohituka is highly valued tree species for the humans, environment and forestry. The tree is distributed some parts of India but now it is endangered species in many areas in the country. This tree belongs to Meliaceae family. Twin, triple, four and five shoot seedling is one of the abnormalities of seedling which produce single embryo in a seed. This could be due to some developmental errors that occur in the seed. A. rohituka have only one embryo per seed and it produced into one seedling. I had recorded 35 % seeds of A. rohituka produced twin, triple, four and five shoot seedlings. In this research paper studies, Germination, seedlings behaviour and four months growth status were recorded in A. rohituka. These are study parameters, germination percentage, abnormal seedlings percentage, seedling behaviour and growth status at 120 days after germination period. I had recorded two shoot seedlings survival at only early stages (within 60 days) of development but triple, four, five shoot seedlings not survive of A. rohituka. It was observed first time growth status of abnormal seedlings in A. rohituka. This research paper utility in various fields such as forestry, agriculture, environment, genetics, and embryology.

The paper presents the modeling, simulation & analysis of Speed Controller for a Brushless DC Motor. Performance comparison between a position sensor and sensorless based speed control is also presented in the paper. Hall effect Sensors have been used for position sensing and back emf based method has been used for determining the position of rotor in position sensorless scheme. The speed controller has been implemented by incorporating PI controller and hysteresis current controller in MATLAB Simulink. Hysteresis current controller was used to generate PWM pulses for inverter switches. IGBT based inverter was used for conversion of DC power to AC power.

Skill development is an important driver to address poverty reduction by improving employability, productivity and helping sustainable enterprise development and inclusive growth. It facilitates a cycle of high productivity, increased employment opportunities, income growth and development. However, this is just one factor among many affecting the productivity whose measurement differs for individuals, enterprise and economy. The increase in productivity could be due to availability of skilled & healthy manpower; technological up gradation and innovative practices; and sound macroeconomic strategies. The manifestations of improved productivity can be in the form of improvement in real gross domestic product (economy), increased profit (enterprises) and higher wages (workers). In this study, an attempt has been made to conceptually analyse the skill development process in India and the agencies involved in its promotion.

Unified Modeling Language has been widely used in software development for modeling the problem domain to solution domain. The major problems lie in comprehension and testing which can be found in whole process. Program slicing is an important approach to analyze, understand, test and maintain the program. It is a technique for analyzing program by focusing on statements which have dependence relation with slicing criterion. Program slicing is of two types (i) Static slicing (ii) Dynamic slicing. Dynamic slicing refers to a collection of program execution and may significantly reduce the size of the program slice because runtime information, collected during execution, is used to compute the program slice. In this paper we introduce an approach for constructing dynamic slice of unified modeling language (UML) using sequence diagram, state chart diagram, class diagram along with the activity diagram. First we construct an intermediate representation known as model dependency graph. MDG combines information extracted from various sequence diagrams along with those from class, state-machine, sequence diagram and activity diagrams. Then dynamic slice is computed by integrating the activity models into the MDG. Finally for a given slicing criterion test cases has been generated.

In this paper we have investigated the steady plane poiseuille flow of viscous incompressible fluid between two porous parallel plates in magnetic field. We have studied the velocity, average velocity, shearing stress, skin frictions, the volumetric flow, drag coefficients and stream lines.

This paper is the study on setting up a solar PV system plant and rooftop system in the northern hemisphere of India. It includes brief explanation on structure, calculations based on the approximated data collected from the 5MW plant and maintenance required to get the maximum efficiency of the plant. However many locations around the world have years of weather records that will provide average data which is sufficient for designing a PV systems and if no long term data exists for the chosen site, in that case the availability of sun light and the amount of sunshine can also be estimated with the help of available equipments.

This study was to investigate perceptions of selected International Islamic University Malaysia (IIUM) students’ regarding the definition and manifestation of Comprehensive Excellence in the university’s vision and mission statement of Integration, Internationalization, Islamization, and Comprehensive Excellence (Triple ICE) – irrespective of gender, nationality or academic achievement. Individual interview sessions lasting between 45 minutes to 55 minutes were conducted on selected IIUM students at separate venues and times. Each dimension was transcribed from the interview questions and decoded into a template. Main ideas were extracted from the template to answer the research questions within the purpose of the study. Two selected co-raters were identified to evaluate the main ideas of the researcher’s template in order to assure its reliability and validity. A percentage range of 96% to 100% showed that the items were highly reliable and valid. The results showed that Comprehensive Excellence was understood by a selected group of students only, thus more students need to be exposed to the conception of Comprehensive Excellence and other components of Triple ICE of the International Islamic University Malaysia (IIUM). This study may aid IIUM to compete and excel with other universities – locally and/or internationally as well as to prepare employable and marketable graduates.

In the present communication novel tris(hetroaryl)bisazo dyes were synthesized by the coupling of various heterocyclic diazonium salt with 1-ethyl-6-hydroxy-4-methyl-2-oxo-5-((4-phenylthiazol-2-yl)diazenyl)-1,2-dihydropyridine-3-carbonitrile. The later compound was synthesized by a new procedure for the synthesis of well known azo pyridone dyes from 2-cyano-N-ethylacetamide, ethyl-3-oxobutanoate and 4-aryl-2-aminothaizole. Structural confirmation of all the synthesized compounds have been accomplished by UV-Visible, FT-IR, 1H-NMR,13C-NMR and mass spectroscopic techniques. Solvent effects on the visible absorption spectra of the dyes were evaluated. The color of the dyes is discussed with respect to the nature of the heterocyclic ring and substituent present therein. All these dyes were applied as disperse dyes on to polyester fabrics and their fastness properties were evaluated.

The research on Study Habits and Students Academic Performance in English Language among Public Secondary Schools in Oron Local Government Area of Akwa Ibom State was conducted in order to seek solution to the increasing nature of poor academic performance of students in English Language among Public Secondary Schools in Oron Local Government Area. Four variables were adopted to include participation in tutorial classes, attendance to classes, use of library and personal time table, which aimed at finding the relationship between each of those variables with academic performance of students. Four research questions and four research hypotheses were set. The related theories of learning used are connectionism, cognitive and psychological theories of learning. The population of study comprises all the 3 Public Secondary Schools in Oron Local Government Area. The instrument used for the study was Study Habit and Academic Performance Questionnaire (SHAPQ) which has a reliability coefficient of 0.99 using Pearson Product Moment Correlation (PPMC) at P<.05 level of significance. The sample size was 200 students and data collected from the respondents were analyzed using PPMC with the degree of freedom of 198 at 0.05 level of significance. The result of data collections were drawn that: students should participate in tutorial classes, attend classes, use the library and should have a personal time table to improve academically. In conclusion, students should develop good study habits to achieve better academically and otherwise.

We report a case of a young patients with a residual mass surgery of a testicular cancer which was outside the recommended territories. This surgery was justified by the persistence of mass after chemotherapy , and more than a year after surgery our patient presents good evolution both clinical , biological and radiological .
