Supervisors are expected to observe how student teachers prepare, deliver the lesson and conduct themselves as members of teaching profession and are expected to advise the students on how to improve their teaching skills. The present study is a descriptive survey which sought to analyze student teacher’s perception towards teaching practice as an exercise for grading or improvement and examine student teacher’s perception towards student-supervisor comments during discussion after classroom assessment. The sample comprised of 50 second year Diploma in Education who had undergone teaching practice in 2016. The students were purposefully sampled. In purposeful sampling, the researcher selects the participants because they possess particular characteristics or knowledge being sought. A questionnaire was used to collect data for this study. The findings indicated that majority of student teachers who participated in the teaching practice perceived that the supervisors gave grades which did not reflect the comments made about the teaching performance of the student teacher. Based on the findings recommendations were made, among others, that assessment should match the comments on areas needing improvement and meaningful accompanying comments should be made to guide student teachers in the desired directions during teaching practice, encourage student teachers to try harder or to give credit for work done well.

The student of AMA University persistence in computing which has the keys to providing their talent needed to fill the computer laboratory in the computing professions. A range of factors can affect a student’s decision to remain in a computing major or change to another major if ever they feel that computing education is difficult. This has to describe the activities in computer laboratory specifically exercises, machine problems, and computing case studies interacting different application programs as the basis of their skills and knowledge in programming capability. The nature of those activities addresses by using of IDE as open source in all programming applications which may result of specific intervention such as using the editor to create a source file, the code blocks, comments, and program statements are entered and the file saved. In case, there are no "corrective actions," taken as the editor does not know this is supposed to be a "source file" as opposed to notes for class. If working in a position-dependent language like Java, the developer would have to be very careful about indenting. The file has to be saved with the correct file extension and in a directory where the compiler can find it. Each source file has to be compiled separately, if the program has a few source files, they all have to be named separately in the compiler. When invoking the compiler, it has to be directed to look in the correct directory for the source files and where the output files should be stored. If there is an error in the source file, the compiler will output messages and fail to complete. For any errors, the developer goes back and edits the source file, working from line numbers and compiler messages to fix the problems and these steps continue until all the source files compile without errors. When linking, each object file is specified as being part of the build. Again, the locations for the object files and executable are given. There may be errors at this point because it is not until the entire program is linked that some errors can be detected. Assuming the linker finds all the variables and functions, it produces a file that can be run. If the program is running and working means all well for the developer. If it seems to do nothing, that means it's debugging time, since there is no insight to what the program is doing, the developer may go back and put in some brute force methods, like print statements to print messages out at certain points in the program or blink some light emitting diodes (LEDs) at strategic places, which means back to the editor, and the cycle continues. These are the causes of the developer can sort of sounds like rather than copying and pasting code from previous applications into a new one, that are rewriting the same functionality again and again. This is one of the varied reasons of the dry principle is geared more towards not having the same functionality duplicated throughout an entire system, but reusing code from other applications is better than rewriting it, since IDE is free and available as open source in any codes of environment. The main focus of the study is the development of utility for locking editor in protecting software exercises. Specifically, it sought to solve the following: To develop an editor that will lock the source code during programming laboratory exercises; To assess the propose system in Kirkpatrick model approach; To evaluate the testing assessment of the proposed system in terms of the following indicators: Efficiency, Usability, and reliability As the result, the locking editor for source code generation is a core program for the locking IDE software. It contains both the user interface such as students and instructor which work together in one package. The evaluation of multi-programming environment by testing the editor that, as it develops solutions keep in mind that locking editor uses the architecture and frameworks that most users are accustomed to see. It should build the development environment and use the tools in the way that makes the most sense for organization. The assessment of the proposed system in Kirkpatrick model approach such as reaction, learning, behavior and results with a weighted mean of 4.19, 4.37, 4.25 and 4.67 with a verbal interpretation of “Protectable” and “Highly Protectable” respectively. The determination in testing assessment of the proposed system based on ISO 9126 reveals of efficiency, usability and reliability with a weighted mean of 4.19, 4.58, and 4.75 interpreted “Highly Protectable” and “Protectable” respectively were the main features and characteristics of locking editor.

Java™ 2 Platform, Enterprise Edition (J2EE) is a set of specifications, for developing enterprise-level applications created by the JCP (Java Community Process). In simple terms it provides a standard for developing multitier, enterprise applications. Advancements in technology further enhanced the need for scalable, efficient and faster solutions for information management. The JEE technology is best suited when it comes to meeting these requirements. J2EE architecture has various layers working in unison. These include the client, presentation, business logic and data access layer. The client tier acts as the interaction point between the client and the application. The presentation layer is where an interface is generated dynamically using different components. These components may include Servlet’s and JavaServer Pages (JSPs), or standalone Java applications. The middle tier is also called as the server tier. Enterprise beans and Web Services encapsulate distributable, reusable business logic for the application in the next tier which also happens to be known as the server tier. The forth tier handles connections with the respective databases.

The poor acceptance of the implementation of the private sector partnership in the financing of infrastructures in Nigeria was discussec in this paper, where it was identified that skill and competence, unethical practice, low political influence and capacity building were some of the challenges facing Estate managers in discharging their statutory roles in implementing private partnership on infrastructure financing in Nigeria. The policy implication of this is that, if these challenges are not urgently checked and corrected within the shortest time, the home based professionals may lose its relevance in practical sense in core service areas. If we want to claim monopoly of our role as prescribed by the law and not doing things right, I want to bring to our notice that some multinationals have been importing Valuers/assessors from overseas since they are not satisfied with the home- based service provider.

Military aircraft engines employ afterburner system for increasing the thrust required during combat and take-off flight conditions. V-gutter is employed for stabilisation of the flame during reheat. For fifth generation aero engine the gas temperature at the start of the afterburner is be-yond the allowable material limits of the V-gutter so it is required to cool the V-gutter to obtain acceptable creep life. The design of cooling configuration for the given source pressure is worked out for different rib configurations to obtain the allowable metal temperature with minimum coolant mass flow.1D network analysis is used to estimate the cooling mass flow and metal temperature for design flight condition. CFD analysis is carried out for four cooling configurations with different rib orientations. Out of four configurations one configuration is selected for the best cooling configuration.

This paper presents geothermal exploration and their geothermometric characteristics in the western part of Yemen. Geologically this volcanic province totals areas approximately 45,000 km2. Tectonically the study area is considered one of the most active in the Arabian Plate boundaries that affected by the opening of the Red Sea and the Gulf of Aden as well as by the African rift valley. Extensive field work had been carried out to evaluate the geothermal characteristics of this area. Water and gas samples were collected from hundreds of thermal springs and shallow domestic wells and geochemically analyzed and reported. Temperatures and PH values range from 35 to 96.3 °C and from 4.5 to 8.5 respectively. Deep geothermal gradient indicates that the geothermal gradients in the western part of the province (Red Sea coast) are relatively high up to 182 °C at the depth of 3290 m. Volcanic units are affected by hydrothermal processes and became intensively altered. By applying geothermometric methods, four geothermal fields have been primarily identified, they are: Al-Lisi and Isbil (Dhamar province); Al-Qafr (Ibb province); Damt (Dhala province) and the Red Sea coast geothermal fields and three water types were recognized which are Na-HCO3-Cl-S and Ca-Na-Cl and Na –HCO3.Results from Al-Lisi and Isbil geothermal area are considered the most promising field. Geothermal detail studies have been achieves and location of the first geothermal exploration well is located in Al-Lisi and Isbil field.By applyig geophisical methods Iso- Resistivity contour maps,these maps reflected high resistivity areas and low.Clearly shows the low resistivity values incentral and Western part of the study area about 11Ωm,While up Resistivity values to the area in the eastern 600Ωm.Also through the use ofthe different current electrode spacing (AB/2) 700, 1000, 1500, and 2000m.We find the low- Resistivity areas becoming more widespread and concentrated in the center of the study area and shrink high - Resistivity areas.Indicating increased electrical conductivity with increasing depth.

With the increasing demands of world biotechnology industries, there is a need to enhance the productivity, reaction stability, reusability and shelf life of enzymes. So, novel techniques are required to facilitate large scale and economic formulations. Enzyme immobilization is done in order to meet all the challenges to enzyme activity. It provides an excellent base for increasing availability of enzyme to the substrate with greater turn over a considerable period of time. This can be done by entrapment, support binding, cross linking of enzyme crystals, etc. Several natural and synthetic support materials are used for the immobilization of enzymes. These increase the efficiency of an enzyme to a great extent. Nowadays, immobilized enzymes are preferred over their free counterpart due to their prolonged availability. Immobilized enzymes are widely used in pharmaceutical industries, cosmetic industries, food processing, biofuel production and many other sectors.

A consensus among the global scientists essentially expanded as the changes in climate developed and these sharp changes are expected to happen when the earth’s system is stretched across thresholds. Climate change is one of the global most imperative themes in our own time because of its consequences waiting for the upcoming generation. This paper aimed at assessing the impacts of climate change on the wheat production in the United Kingdom during the two development stages (Grain filling and Grain ripening) over the 30 years period from 1982-2011. A gridded meteorological data from UKCP09 was used to get the mean for the wheat development period that is most sensible to climate (June to September). This was correlated with the UK wheat yield data retrieved from the department for environment, food and rural affairs (DEFRA) using Microsoft excel and R statistical software. The results revealed a highest increase in temperature than rainfall during the wheat development period and that temperature is having more impact on wheat yield in the UK than rainfall. It is also found out that climate change is only but a factor among other factors that influenced the wheat yield in the UK for the past decades. Other factors such as genetic improvement, better changes in cultivating practice, better management of pests and diseases and high application of NPK fertilizers could have more effect on the UK's wheat yield for as far back as decades than only a change in climate.

The objective of the study was to identify the parameters of soil damage, so that the level of damage that occurs was known, as a decision-making material with an appropriate approach to the problem, so that the productivity of the land does not decrease, even increased as a cultivation area that has a function for biomass production. The first step is to determine the potential for indicative soil damage by overlaying with the GIS-based digital map, i.e. soil type map, slope, rainfall, land cover, then with the spatial and regional plan map. The results obtained 4 classes of potential indicative soil damage, namely low (1), medium (2), high (3) and very high (4). Observations were made at (3) and (4). Number of field observation points and soil samples respectively 4 and 2. Field verification found that an effective soil depth (solum thickness) at (3) was ≥90 cm, 25-40% slopes were used for agriculture, whereas (4) was <20 cm and ≥60% only secondary forest. The results of the evaluation found that 5 parameters exceeding the threshold, namely solum thickness (s), surface of rocks (b), permeability (p), soil acidity (a) and electrical conductivity (e). Based on the relative frequency score, the soil damage status is slightly damaged at (3) by limiting factor (a) or D.I-a, while at (4) moderately damaged by limiting factor (s), (b), (p) and (e) or D.II-s, b, p, e. Improvement actions in D.I-a are soil treatment, organic fertilizing (compost) and liming, whereas in D.II-s, b, p, e is difficult to repair due to natural factors.

Kathmandu Metropolitan City (KMC) is the stage of rapid urbanization and its population is on steep rise with increase in economic activities. Many people are migrating to KMC from other parts of the country for job opportunities. In Urban mobility, work trips have a dominant share and at present, people are dependent more on private vehicles, than public transport to go to their work places, which is adding more to road congestion. This research investigates the travel behavior of employees, living in KMC and its relation with four main variables related to Socio-demographic background of an employee, i.e. age, gender and income group and household vehicle ownership. Data was collected by household questionnaire survey of over 1000 households. Different descriptive analysis and inferential statistical analysis were carried and it shows that role of socio-demographic variables on travel behavior is quite significant in many aspects on choice of travel mode and trip length of employees. Finally, the findings of the research were incorporated with the policy implications, so as to increase the use of public transport for work trips.

Fullfilment for the needs of housing is a priority that cannot be suspended, especially in urban areas of developing country whose population continues to increase because of the rapid urbanization. Indonesia as the developing country still has a fairly high backlog approximately at 7.6 millions unit house in 2014, most of them are low income people. The Government has several plan in striving for the scarcity of housing. One of them is the development of rental flats which have goals for the social housing fulfillment for low income people and increase their housing affordability by lowering the rental rates. The intention is to assist the low income people save their money to buy their own homes. But in facts, there are several constraints related to this rental flats finance, such as late payment by the residents, uncontroled right transfer, and the tariff adjusted to the ability of the inhabitants, can not cover the cost of the physical building management and maintanance. This study aims to evaluate Sombo rental flat finance for for low income people, in which the data are collected through in depth interview, observation, and documentation. The results of several qualitatively descriptive analysis show that the effectiveness of rental flat financing in the aspect of the purpose and goal to facilitating low income community needs of housing is quiet accomplished. Beside that, the organization is also well structured and have the efficient human resources. But Sombo rental flats effectivenes is relatively low in the aspect of profit ability, rental financing program, and in the enforcement of rules and regulation. The main problem is in the arrears of residents rental payment and the deficiency for maintanance cost so it has to depend on the city government subsidies. The rental finance constraint are caused by several factors, which are historic factors, resident’s factors, and the vision and commitment of the city government to facilitate housing for low income people in Surabaya City.

The demand for large diameter pipes in terms of their strength and toughness properties is increasing day by day. The quality and mechanical strength values of the steels, used in new gas pipeline projects, are gradually increasing. Today, high strength steels are used instead of the steels with low yield values. In this study, the micro-structure mechanical properties of the high strength X70 steel, used in the Trans Anatolian Gas Pipeline Project (TANAP), were investigated before and after the welding process and the weld zone was examined. The submerger arc welding process has been employed for the weld process. While the mechanical properties were determined by tensile, notched bend impact, bend and hardness measurements, the microstructures were examined by using optical microscope and scanning electron microscope (SEM). The radiographic and ultrasonic methods were employed in the non-destructive test of the weld zone.

The aim of this paper is to study the mechanical behavior of knitted fabrics, which are used in protection gloves, at large deformation and different strain rates in terms of extension/recovery cycling. The non linear viscoelastic model, proposed here, is based on the standard solid model. It contains three nonlinear spring and damper elements. The idea is to consider that, by analogy with elastomers, the mechanical behavior of the fabric in terms of hysteresis loop is due to the contribution of two parts: the first one represents the equilibrium state of the fabric and the second one is due to the deviation from this equilibrium. Then, the stress-strain behavior of the fabric at different strain rates can be computed using the same parameters determined at one value of strain rate. A good agreement has been obtained between the experimental and theoretical results.

It is proposed that the ball lightning and UFO are analogous objects. The variety of different observations is explained. It is proposed on a uniform basis using a hypothesis that the ball lightning and UFO are created like a spherical capacitor filled by polar molecules mainly and in some cases by various chemicals which influence the final manifest of the object. A mechanism of a formation of the spherical capacitor is discussed. A peculiar behavior like e.g. sudden change of direction of motion, shape of disc and possible penetration through wall is explained as a consequence of internal structure of the object. Finally an experimental verification of the hypothesis is suggested.

The presence of heavy metals in landfill leachates poses a risk to the environment, especially in the unpaved dumps where their dissipation in groundwater might occur. This study is focused on the assessment of heavy metal load in landfill leachate of El Hajeb (Morocco) and their effects on the environment in general. To do this, raw leachate samples were collected monthly from basins available at the heart of the landfill and analyzed using the atomic absorption spectrophotometer (AAS) to quantify the heavy metals during the period which extends of May, 2015 to February, 2017. The results showed the presence of Pb (2.68 mg/L), Co (0.92 mg/L), Hg (0.009 mg/L), Cr (5.14 mg/L), As (1.95 mg/L), Cd (0.41mg/L) and Mn (61.52 mg/L) in significant amounts. What makes these extremely toxic effluents and thus presented a potential danger for the health of the riparian population and the adjacent groundwater. The determination of heavy metals content will thus make it possible to orient the choice of the leachate treatment process to answer the strictest standards of rejection.

This research work focuses on developing an amplitude modulation index based equation that can predict the harmonic content in the conventional seven-level cascaded H-bridge multilevel inverter (CHBMLI) at low switching frequency. A logic circuit using phase opposition disposition pulse width modulation (PODPWM) scheme is used for the seven-level CHBMLI. The multilevel inverter (MLI) is simulated for amplitude modulation indices from 0.10 to 0.26.The simulated and calculated results of the harmonic content in the output voltage at amplitude modulation index of 0.20 produce minimum values of 16.61 % and 13.00 % respectively. The harmonic content from the amplitude modulation equation, on average, deviates from the simulated result by 2.74 %. Simulation results are obtained using MATLAB/SIMULINK software.

Fatty acid composition of plant food (oil) is important for its economic and nutritional value. Assessment of fatty acid contents of two Nigerian masticatories cum traditional snacks: African walnut kernel (AW) and African elemi pulp (AE) were carried out. Samples were subjected to graded wet heat contact time based on their traditional methods of processing and their oil extract evaluated for fatty acid (FA) contents using chromatographic method. The processing methods had no statistically significant effect on both the oil and FA contents of the samples. Both samples contain nutritionally relevant levels of fat ranging respectively from 49.8±1.08 to 52.8±2.70g/100g sample and 41.93±6.03 to 42.8±4.61g/100g sample in AW and AE. A total of six fatty acids including two essential ones namely omega-6 (C18:2) and omega-3 (C18:3), were identified and quantified in the two plant foods. The predominant FAs in the plant foods were oleic acid (16.12±1.86 - 17.11±1.31g/100g fat), linoleic acid (16.88±1.66 - 18.80±1.52g/100g fat) and linolenic acid (55.95±5.68 - 57.08±6.57g/100g fat) in AW and palmitic acid (48.59±4.35 - 50.51±3.29g/100g fat), oleic acid (32.02±3.27 - 35.74±1.46g/100g fat) and linoleic acid (15.15±3.57 - 15.40±3.82g/100g fat) in AE. The study shows that on the average, one serving of AW could supply about 41.52% and 647.09% of the Recommended Daily Intakes (RDIs) for the essential FAs Linoleic and Linolenic acids respectively, while that of AE will supply about 29.13% of the RDI for Lineleic acid. Based on their essential FAs contents the plant foods apparently have potentials for applications as nutraceuticals.

Today, Computing technologies are becoming the pioneers of the organizations, and helpful in individual functionality i.e. added to computing device we need to add softwares. Set of instruction or computer program is known as software. The development of software is done through some traditional or some new or evolutionary models. Software development is becoming a key and a successful business nowadays. Without software, all hardware is useless. Some collective steps that are performed in the development of these are known as Software development life cycle (SDLC). There are some adaptive and predictive models for developing software. Predictive mean “already known” like WATERFALL, Spiral, Prototype and V-shaped models while Adaptive model include agile (Scrum). All methodologies of both adaptive and predictive have their own procedure and steps. Predictive are Static and Adaptive are dynamic mean change cannot be made to the predictive while adaptive have the capability of changing. The purpose of this study is to get familiar with all these and discuss their uses and steps of development. This discussion will be helpful in deciding which model they should use in which circumstance and what are the development step including in each model.

In order to study the mechanical behaviour of elastomers at large deformations, a theoretical description was developed for the loading-unloading hysteresis loop at large deformations and as a function of the strain rate. Bergström and Boyce’s proposition that the elastomer behaviour is controlled by two contributions, the first one corresponding to the equilibrium state and the second one to a non-linear rate-dependent deviation from that equilibrium state, and their use of Zener’s rheological model, were applied to an uniaxial tension configuration. A validation of the description was performed with nitrile rubber. A good agreement of the theoretical description with experimental results was obtained. This simple description of the hysteresis behaviour of elastomers as a function of the strain rate provides a useful tool for estimating the mechanical behaviour at various strain rates, with potential application in the design of protective gloves.

The digestive system, hence digestion of food is usually one of the topics taught at the secondary and tertiary levels of education. Often, this topic is taught using teaching aid in the form of diagrams or charts drawn on plane papers. The inanimate nature of these teaching aid employed makes learning less interesting and comprehension difficult. This paper presents the design and construction of a semi animated digestive module with remote control that visualizes the movement and process of food digestion in the body. Basically, the system consists of carved wooden digestive organs with light emitting diodes (LEDs) carefully fixed on the path of digestion. A remote control is also built to aid remote access to the module. These LEDs start to blink indicating swallowing from the mouth down to the anus illustrating the process of digestion which also involves the production of enzymes. A comparison of with the improved teaching aid will make conventional types showed that it aroused student, interest during teaching and learning process.

Plants are rich sources of antioxidants that are protective against diseases associated to oxidative stress. There is a need for high throughput screening method that should be useful in determining the antioxidant concentration in plants. Such screening method should significantly simplify and speed up most antioxidant assays. This paper aimed at comparing the applicability of a semi-automated clinical chemistry analyzer (Pointe Scientific, MI, USA) with the traditional standard curve method and using a Vis spectrophotometer in performing the DPPH assay for antioxidant screening. Samples of crude aqueous leaf extract of kulitis, Amaranthus viridis Linn, and chayote, Sechium edule Linn, were screened for the Total Antioxidant Concentration (TAC) using the two methods. Results presented in mean ± SD (μg/dl) were compared using unpaired Student’s t-test (P<0.05). All runs were done in triplicates. The mean TAC of A. viridis was 646.0 ± 45.5 μg/dl using the clinical chemistry analyzer and 581.9 ± 19.4 μg/dl using the standard curve-spectrophotometer. On the other hand, the mean TAC of S. edule was 660.2 ± 35.9 μg/dl using the semi-automated clinical chemistry analyzer and 672.3 ± 20.9 μg/dl using the spectrophotometer. No significant differences were observed between the readings of the two methods for A. viridis (P>0.05) and S. edible (P>0.05). This implies that the clinical chemistry analyzer can be an alternative method in conducting the DPPH assay to determine the TAC in plants. This study presented the applicability of a semi-automated clinical chemistry analyzer in performing the DPPH assay. Further validation can be conducted by performing other antioxidant assays using this equipment.

The corrosion caused by chemical reaction between metallic structures and surrounding mediums, such as soil or water .the (CP) cathodic protection system is used to protect metallic structure against corrosion. Cathodic protection (CP) used to minimize corrosion by utilizing an external source of electrical current which forces the entire structure to become a cathode. There are two Types of cathodic protection system (Galvanic current, Impressed current).the Galvanic current is called a sacrificial anode is connected to the protected structure (cathode) through a DC power supply. In Galvanic current system ,a current passes from the sacrificing anode to the protected structure .the sacrificial anode is corroded rather than causing the protected structure corrosion .protected structure requires a constant current to stop the corrosion which determined by area, structure metal and the surrounding medium. The rains, humidity are decrease soil resistivity and increase the DC current .The corrosion and over protection resulting from increase in the DC current is harmful for the metallic structure. This problem can be solved by conventional cathodic protection system by manual adjustment of DC voltage periodically to obtain a constant current .the manual adjustment of DC voltage depends on experience of the technician and using the accuracy of the measuring equipment. The errors of measuring current depend on error from the technician or error from the measuring equipment. the corrosion of structure may occur when the interval between two successive adjustment is long .An automatically regulated cathodic protection system is used to overcome problems from conventional cathodic protection system .the regulated cathodic protection system adjust the DC voltage of the system automatically when it senses the variations of surrounding medium resistivity so the DC current is constant at the required level.

The process of modern urbanization in Ethiopia began to take shape since the later part of the nineteenth century. The territorial expansion of emperor Menelik (r. 1889 –1913), political stability and effective centralization and bureaucratization of government brought relative acceleration of the pace of urbanization in Ethiopia; the improvement of the system of transportation and communication are identified as factors that contributed to this new phase of urban development. Central government expansion to the south led to the appearance of garrison centers which gradually developed to small-sized urban center or Katama. The garrison were established either on already existing settlements or on fresh sites and also physically they were situated on hill tops. Consequently, Limmu Genet town was founded on the former Limmu Ennarya state’s territory as a result of the territorial expansion of the central government and system of administration. Although the history of the town and its people trace many year back to the present, no historical study has been conducted on. Therefore the aim of this study is to explore the history of Limmu Genet town from its foundation up to present.

The various approaches of separating baseflow from other streamflow components are hinged on their respective strengths and drawbacks with respect to the watershed considered. Little wonder therefore, that this research work has ventured on some methods amongst multitude of emerged methods, to establish the best method(s) of baseflow separation and henceforth address the strength and drawback dichotomy associated with the different baseflow separation methods. The examined methods of baseflow separation used in this work are conveniently categorized into five basic approaches of fixed interval, sliding interval, local minimum, Baseflow Index and frequency analysis. Data for the analyses obtained from Otamiri River at Nekede were utilized for this study and daily recorded streamflow discharge data obtained from the historical records held at the libraries of the Anambra Imo River Basin Development Authority, Owerri and the Nigerian National Meteorological Services. The results of the predictability of the stream flow from the estimated baseflow for all the methods used conformed as evident in the regression analysis and the results showed that the value of the coefficient of simple determination (r2) was highest in the fixed interval method and least in the frequency analysis method which implies that the fixed interval method was the best method of separating the base flows for Otamiri stream.

Matthew, the oldest son of Mr. Joni and Mrs. Hani cannot speak normally although he is four years old. He will get furious by hitting his head and keeping rolling around on the floor if we do not fulfill his want. The parents have to struggle hard to make their son grow and develop normally like other normal children. Besides sending him to a Special School, they also use their own method to cure his retardation. The research used a case study by finding out the inter-personal communication between Matthew and his parents. The data were gathered by conducting in-depth interviews with the parents and observation on the communicative activity between Matthew and his parents in order to get triangulation data. The result of the research showed that 1) the paradigm used was symbolical interactions which explained the method of communication between parents and their son who underwent Speech delay, 2) the theory used in the research was the theory of effectiveness in communication, 3) The result found that family was the environment where children spent most of their time during their growth; therefore, parents should provide an favorable environment which supports their children’s growth and development.

Staying in the termination environment for a long time as well as very limited facilities is certainly very influential on the physical and psychological development of children Rohingya refugees. Limitations of interaction with the surrounding environment, limited financial condition of the family, unmet need for continuing education and environmental conditions and shelter that has not been fully adequate. This condition certainly affects the rate of development of refugee children, some of whom are very anxious and feel they have no future. Based on the initial observations of refugees both parents and children are very open, the main problem is that there is no certainty in the future when they will be placed into a third country and the lack of educational facilities for their children. The average family of refugees has been living in a termination of more than 5 years. Parent-child communication can affect the overall functioning of the family and the psychosocial well-being of the child (Shek, 2000). Therefore, the role of parental communication is needed to overcome traumatic in the Rohingya refugee children. This study aims to find out how the parent communication to overcome the traumatic conditions of children by forming children's self-concept, giving recognition and support, and create models. The research method used is descriptive qualitative method by collecting data through interviews to some parents and children in termination both experiencing direct violent conflict and discrimination that happened in during their stay in their country Interpersonal communication between parents and their children in a conflicting situation was interested to be analyzed by using Coordinated Management Meaning Theory because in a conflicting condition parents should set their psychological condition aside as the traumatic victims. The result of the research showed that the function of parents’ communication with their children could help solve the children’s traumatic condition by developing their self-concept, give recognition and complete support, and apply exemplar model to them so that they could reduce their trauma. It could be seen through the increase in their activity and their willingness to self-actualize by continuing their study and their transparency toward their surrounding.

Nowadays, people suffering from obesity/cholesterol are often heard. This disease is due to the excess of mainly carbohydrate and lipid in an individual’s diet and the lack of expenditure of energy such as exercise. Therefore, the patawali plant, or its scientific name, Tinospora crispa is believed to be a traditional cure for the problem. A sample of patawali plant (Tinospora crispa) juice, lime juice, ginger juice and grapefruit juice was prepared for the experiment. Next, fresh chicken fats are chosen and prepared as they contain a high value of cholesterol. The chicken fat was rinsed with water, dried using a filter paper and then immersed in the juice samples for a duration of 1 hour. The initial and final mass of chicken fat was recorded. At the end of the experiment, it is found that ginger and Tinospora crispa shows significant in reducing the mass of chicken fat. Thus, it can be concluded that Tinospora crispa and ginger has the potential to be the future cure for obesity.

Rabin-Karp is one of the algorithms used to detect the similarity levels of two strings. In this case, the string can be either a short sentence or a document containing complex words. In this algorithm, the plagiarism level determination is based on the same hash value on both documents examined. Each word will form K-Gram of a certain length. The K-Gram will then be converted into a hash value. Each hash value in the source document will be compared to the hash value in the target document. The same number of hashes is the level of plagiarism created. The length of K-Gram is the determinant of the plagiarism level. By determining the proper length of K-Gram, it produces the accurate result. The results will vary for each K-Gram value.

The diversity of multidrug-resistance (MDR) of pathogenic strains to antibiotics, most widely used for treatment of human diseases in the Republics of Armenia and Nagorno Karabakh were examined. It was shown, that difference of resistance of pathogens to antibiotics depends on their isolation sources. It was shown, that bacteriocin containing partially purified preparations, obtained from different strains of Enterococcus faecium and durans species, isolated from various samples of matsun, salted cheese and other acid milk products from milk of different domestic animals from rural households, inhibited the growth of multidrug-resistant bacteria belonging to different taxonomic groups with different efficiency.

Influence of processing parameters on flexural properties of injection moulded polypropylene was investigated using response surface approach. Investigations were focused on the rheological behaviour of injection moulded polyvinyl chloride (PVC) products at different temperature. Flexural strength test was conducted on the test specimens moulded at different injection parameters ranging from 1700C to 2100C barrel temperature, 33 seconds to 43 seconds cooling time, 46 rpm to 56 rpm screw speed and 350C to 450C mould temperature. The test information was subjected to design expert 10.1 analyses. The results obtained indicate that a melt temperature has an effect on viscosity of injection moulded polyvinyl chloride. Also, optimum parameter values of 390C mould temperature, 52 rpm screw speed, 1900C barrel temperature, cooling time and flexural strength respectively were obtained. The results of this finding will be useful in polymer industries were polyvinyl chloride is been used as a raw material during injection moulding were flexural strength is a paramount requirement of the output component.

This study aims to present experimental studies on the dispersion of immiscible liquids in agitated vessels for a range of liquids and geometries under both batch and continuous conditions. Preliminary experiments were first carried out in a small scale single –stage mixer-settler unit operating with the 20% TBP/OK, 0.05M nitric acid, uranyl nitrate system. This work was followed by measurements of drop size distribution in agitated liquid-liquid systems in 6 and 9 inches baffled and a 20 cm side square tank using six-flat bladed turbine type impellers. The drop size measurement technique employed fiber optic probes and photography. The liquid-liquid systems used for the measurements were methyl-iso-butyl ketone/water, cyclohexane/water and 20%TBP/OK/0.05 nitric acid. The volumetric fractions were 0.10, 0.15 and 0.20 Impeller speeds varied from 300 to 500 r.p.m. A correlation of the mean drop size for the cylindrical and square vessels under both batch and continuous conditions were established.

It has been reported that seeds and fruits, but for their content of antinutrients, could offer a cheap means of providing adequate nutrients to their consumer. The effect of processing on antinutrients contents of the pulp of African elemi, AE (Canarium schweinfurthii) and kernel of African walnut, AW (Plukenetia conophora) consumed as traditional snacks (masticatories) in Nigeria were investigated. The levels of the antinutrients in raw samples of the traditional snacks as well as their corresponding residual levels in samples subjected to graded doses of heat treatment were evaluated using standard methods. Saponins, alkaloids, cyanogenic glycosides and oxalate were obtained in both samples while AE contained tannins and flavonoids in addition. The concentrations of saponins (1.00±0.19) and flavonoids (14.98±2.91) in raw AE and saponins (1.05±0.13) in AW were increased by the processing methods. The rest of the antinutrients were decreased in both samples. The effects on saponins and oxalate became significant (p<0.05) as the processing time was increased. The plant foods, with respect to the tolerable limits of the antinutrients, could therefore be considered safe for human consumption at all levels of processing.

Anti-patterns are poor solution to design and im-plementation problems. Developers may introduce anti-patterns in their software systems because of time pressure, lack of understanding, communication and or-skills. Anti-patterns create problems in software maintenance and development. Database anti-patterns lead to complex and time consuming query process-ing and loss of integrity constraints. Detecting anti-patterns could reduce costs, efforts and resources. Researchers have proposed approaches to detect anti-patterns in software development. But not much research has been done about database anti-patterns. This report presents two approaches to detect schema design anti-patterns in relational database. Our first approach is based on pattern matchingwe look into potential candidates based on schema patterns. Second approach is a machine learning based approach we generate features of possible anti-patterns and build SVMbased classifier to detect them. Here we look into these four anti-patterns a) Multi-valued attribute b) Nave tree based c) Entity Attribute Value and d)Polymorphic Association . We measure precision and recall of each approach and compare the results. SVM-based approach provides more precision and recall with more training dataset.
