Difficulties of concept of function: The case of general secondary school students of Ethiopia[ ]


This study presents investigation of difficulties of grade nine students have on the concept of function using a descriptive survey method. Both quantitative and qualitative research approaches were used to explore the students’ challenges in this study. Data was collected using test, interview and teachers’ questionnaire. The four commonly used ways to represent function is then used to analyse students’ interpretation and manipulation in different contexts. The finding of the study reviled that students have difficulties in basic definition of function, to identify the difference between function and relation, difficulty to identify an equation with two variables x and y as a function or not. The students have also difficulty in verbal and graphical representation of function. Identified students misunderstanding about the function concept are: any functions should contain both x and y variables, any continuous graph are a function and a discontinuous graph is not a function. This could be because of students’ attention to the lesson, their background weakness and students limited English language skills. Based on the findings of the study different recommendations are suggested in order to solve the problems.

Elemental Total Nitrogen (TN): Total Phosphorus (TP) Ratios Influences On The Geological Metal Partitioning In Upstream River Kapsabet, Kenya[ ]


Most aquatic environments normally undergo enrichment with nitrogen or phosphorus resulting in differences in the TN:TP ratios. Ideal TN:TP ratios may affect the overall functioning of the aquatic ecosystems. In this study, the overall impacts of TN:TP were related to the metal concentration along River Kapsabet. Water was collected using plastic bottles and Total nitrogen and total phosphorus analyzed. In addition levels of metals along the sites were analyzed using spectrophotometer. The concentration of TP increased from the upstream to the downstream sites while that of TN reduced from the upstream to the downstream resulting in consistent decline in the TN:TP ratio down the river profile. There were significant differences in the concentration of TN and TP among sites (p < 0.05). In water, the means and ranges in concentration of metals were: (g/L): 0.24 (0.01-0.75) Pb, 0.07 (0.02-0.21) Cu, 2.78 (0.17-3.41) Fe and 0.32 (0.02-1.22) Zn. There was significant (p < 0.05) spatial distribution of metals along the river profile. In both water and sediments, site 3 and 4 contained significantly (p < 0.05) the highest concentrations of Pb, Fe and Zn associated with anthropogenic pollution. This study demonstrate gradient specific increase in total phosphorus along the river profile and associated reduction in total nitrogen resulting in the overall reduction in the TN:TP ratio along the river profile. All metals except Cu displayed increased concentration along the river profile and therefore indicate increased anthropogenic contribution to water enrichment with heavy metals. Yet, along the profile, there was an exponential increase in the concentration of essential metals with increased TN:TP ratio with no association between the TN:TP ratio and the essential Pb. These results indicate that application of the Redfield ratio (TN:TP) ratio may remedy the problem of heavy metal contamination in the aquatic ecosystems.

Performance Improvement of QPSK Modem with AWGN Implemented in FPGA[ ]


This paper presents the methods to design optimized QPSK MODEM with AWGN. The Proposed methods consume less time, power and give better throughput using Spartan-3 and Sparatn-6 FPGA boards. The whole module is divided into several sub modules and those modules are designed using the verilog HDL. Finally, these modules are invoked and integrated to design top level module. Here, two different approaches are used to design the QPSK modulator and they are compared with a conventional QPSK modulator which is designed using arithmetic multipliers and adders. In one of the proposed methods, the modulator is designed by using Vedic multiplier and carry look-ahead adder and demodulator is designed using an FIR LPF with AWGN. The FIR LPF coefficients are generated in MATLAB using a rectangular window and hamming window with AWGN. In the second method, QPSK modulator is designed using multiplexers. The QPSK module is implemented on Spartan-3 and Spartan-6(Atlys) FPGA board. The whole system has been simulated in Xilinx 14.7 and implemented on to the chips XC3S400-4pq208 and XC6SLX45 - CSG324. The results show that the proposed methods can greatly improve the speed and reduce the latency and improve the frequency of operation.

Hydroponics: Producing plants In-vitro on artificial support medium[ ]


With the advent of civilization, open field/soil-based agriculture is facing some major challenges; most importantly decrease in per capita land availability. In 1960 with 3 billion population over the World, per capita land was 0.5 ha but presently, with 6 billion people it is only 0.25 ha and by 2050, it will reach at 0.16 ha. Due to rapid urbanization and industrialization as well as melting of icebergs (as an obvious impact of global warming), arable land under cultivation is further going to decrease. Again, soil fertility status has attained a saturation level, and productivity is not increasing further with increased level of fertilizer application. Besides, poor soil fertility in some of the cultivable areas, less chance of natural soil fertility build-up by microbes due to continuous cultivation, frequent drought conditions and unpredictability of climate and weather patterns, rise in temperature, river pollution, poor water management and wastage of huge amount of water, decline in ground water level, etc. are threatening food production under conventional soil-based agriculture. Under such circumstances, in near future it will become impossible to feed the entire population using open field system of agricultural production only. Naturally, soil-less culture is becoming more relevant in the present scenario, to cope-up with these challenges. In soil-less culture, plants are raised without soil. Improved space and water conserving methods of food production under soil-less culture have shown some promising results all over the World. Growing plants such as Zea mays (Maize), Aloe vera (Indian Aloe), Sorghum bicolor (Sorghum), artificially on sponge support in contact with nutrient medium, it was found that the growth was much more pronounced than the same plants grown on soil. In addition, since only organic nutrients were supplied, the plant products produced were purely organic.

Geotechnical Conditions and Stability Analysis of Landslide Prone Area: A Case Study in Bonga Town, South-Western Ethiopia[ ]


There were several slides and associated ground subsidence which brought significant impact on cracking of walls and floor of several private and governmental buildings in Bonga Town. The principal and secondary roads were also affected by subsidence with vertical displacement up to 1m which hampered the traffic in the town. Water pipelines along the road were disturbed by the sliding which were later repaired. Cracking of the walls and floor of more than 120 private residences and more than 10 government buildings were recorded. The main highway that connects Bonga-Tepi- Masha via Alamo and Gatiba has been disrupted at four locations. This resulted in hampering in traffic for several days. This research aimed to evaluate the cause and failure mechanism as well as the stability condition of the landslides. The study involved the investigation of the Geotechnical parameters of soil and the terrain characteristics to be used for the stability analysis of the slope, including distribution and characteristics of soils, the groundwater table, and the depth and geometry of the failures. The Slope stability analysis is supplemented by using Geo-studio 2004 software. Soil samples were collected, and were tested for grain size analysis, distribution analysis (sieve & hydrometer) plastic limit, liquid limit, plasticity index, water content, unit weight of soil, specific gravity and shear strength parameters following the ASTM procedures. Based on the findings, the landslides were triggered by heavy rainfall. Therefore, the main factors controlling the stability of slope are soil type and characteristics, slope angle, water (surface and groundwater), and slope steepness. The design of retaining wall is recommended to mitigate the impact of landslides in the study area.

Apparatus for measuring Thermal conductivity of fluids[ ]


In recent years Thermal Engineering has developed in many aspects. Due to the development in thermal engineering there is a case for measuring thermal conductivity of the fluids .Thermal conductivity of fluids is measured by Steady state methods as well as Transient method. The Transient Hot Wire has been widely accepted as the most accurate technique over a wide range of fluids. Although the principle of the method is apparent simple, its experimental implementation requires suitable temperature sensing, automatic control, data acquisition, and data analysis systems. Because of the relatively short experimental times and large amounts of parametric data involved in the measurement process, computer control of the measurement is essential. A predetermined current is applied to the hot wire to produce a temperature difference across the fluids. By measuring the temperature differential the thermal conductance of the fluids may be determined.
