Abstract

Ice nucleating bacteria can harm plants by stimulating the formation of ice in their tissues. On the other hand they contribute to cloud formation and rain precipitation on earth. It looks like they can play a role to local weather formation. In the same time the ice nucleating bacteria, has proteins which can bind ice crystal and contribute to the crystals formation. They can be dangerous during late frosts in the spring in orchards, affecting the blossoms, and producing damages and crop looses. They can be used in different purposes, in order to obtain ice in different conditions. The damage in orchards is highlighted. Some bacterial products were issued in order to fight with this kind of frost and to protect plants.

Abstract

In this study, fourteen reinforced concrete beams were tested to investigate the shear behavior of lightweight fiber reinforced concrete beams. Lightweight Expanded Clay Aggregate (LECA) was used as a partial and full replacement to the normal weight aggregate. The experimental program included three lightweight concrete beams with partial replacement of aggregate, nine lightweight concrete beams with full replacement of aggregate, and two normal weight control beams. In each group one beam was cast using steel fiber concrete, one with polypropylene fiber concrete, and one without fibers. The effects of parameters such as weight of concrete, type of fibers, area of stirrups, and shear span to depth ratio (a/d) on the beams behavior are presented. The response of the tested beams is analyzed in terms of mode of failure, deflection, strain, cracking load, and ultimatecapacity. The test results are compared to those estimated from different design codes for lightweight concrete structures.

Keywords: lightweight concrete; shear behavior; failure mode; cracking load; ultimate load

Abstract

The objective of this thesis is centered in the synthesis of a method of design of broadband monopole antennas for the range of HF and VHF. The antenna must have a practical size to be installed in a mobile station (automobile) and the power must radiate omnidirectionally for transmission of interference in the frequency band of interest (20-100MHz). There are several antenna topologies that can be used, each with a variety of options of loaded sections and of them the antenna selected was the traditional monopole antenna of whip type, due to its practical size to be installed in a mobile station and the stability of its structure. With the help of CST Studio Site 2015 software, the simulation and optimization processes of the proposed antenna were carried out. This antenna was numerically optimized taking into account the load elements and considering the return losses (S11), the voltage standing wave ratio (VSWR) and the gain value, among other parameters. The results of the optimal load solution for the monopole antenna are compared to each other to arrive at the best design. The best result obtained is the monopole antenna with four load sections distributed along its length. The simulation results should show that the proposed antenna to meet the specifications of the voltage standing wave ratio below 3 (VSWR<3:1) over the entire frequency band specified.

Abstract

The hydrological rate of flow of the watershed of Lake Laya El Hammam depends on its morphometric and geological features as well as its precipitation.The watershed of Lake Laya El Hammam is part of the coastal watersheds in the central-east of Tunisia. It is the only watershed which is not affected by hydraulic constructions such as dams. Besides, it features a surface area that extends to 204 km2 and a high recorded rainfall. To determine the hydrological rate of flow of the watershed, we had to identify its geological and morphometric characteristics, and gauge the flow of Lake Laya El Hammam. The final results have allowed us to identify: the general aspect of the flow of water in the watershed of Lake Laya El Hammam, the relationship lake/ sheet and the importance of gauging in Eastimating the rate of flow of water during periods marked by lack of rain.

Keywords: watershed, hydrological rate of flow, Lake of Laya El Hammam, Tunisia.

Abstract

Software projects’ past goes back to four or more decades. We encounter the first software project risk management paper in 1991[1] and the study [2] reports that in 1995 US spent $250 billion to software projects and these projects had estimated $59 billion in cost overruns and another $81 billion had spent on canceled software projects.Although failures are tremendous, we have observed the project risks and critical success factors are given like shopping lists and so the remedies of risk factors. Very few studies exist for searching the relationships of these risk factors and the relationship between remedies and risk factors. We are trying to construct a simple model of risks and remedies borrowing concepts from systems and control theory.

Abstract

Today, the most important modes of transportation for cities are public transportation. Public transport provides citizens with fast, reliable, timely and inexpensive transportation.Public transportation systems are constructed according to the size of the cities. Bus systems are the most common means of public transport in small-scale cities. However, as cities grow, the rail system becomes an important model for public transportation. Turkey's largest city of Istanbul has a population of over 14 million. With a 149 km rail system line, it is aimed to create a railway system network of 1.000 km for public transportation in Istanbul. In this context, 276 km railway system construction is continuing. The completion of the investments financed by the municipality and the government at the targeted time and in the desired qualification is very important in terms of the quality of life of the citizens. For the Rail System Lines, risk management is required to achieve the intended objectives. In this study; continuing rail system projects in Istanbul; design, engineering services (supervisor) and construction phases. For the study, a risk matrix was created and a questionnaire survey was conducted with 60 senior experts working on the Istanbul rail system projects in the public and private sectors. Survey results and evaluations were given in the study.

Abstract

Nnewi in the past two decades has grown considerably not only in size and infrastructural development but also as a commercial town to reckon with in Anambra State South-East Nigeria. This work therefore tries to assess the performance of commercial real estate development as an investment option in Nnewi using shops, offices and warehouses. This study is also delimited to old Nnewi-Onitsha road, Edo-Ezemewi Road and Nwagbara Road which are important commercial roads (CBD) in Nnewi. The study tries to determine the performance of the selected commercial uses in the selected roads from 2006 – 2010 and 2011 – 2015. Thereafter a comparison of the two periods was made. The survey research method was adopted. Data was collected through questionnaires distributed to Landlords of commercial properties in the study area, Estate Surveyors and Valuer, property developers in Nnewi and other secondary sources. The hypothesis developed was tested using ANOVA. The study shows a significant difference in the performance of shops offices and warehouses in Nnewi. The study recommended among other things that real estate investors in Nnewi and indeed in Nigeria should seek the help of professionals (Estate Surveyors and Valuers) who will carry out market and consumer preferences research/analysis before they venture into commercial real estate development.

Abstract

A three-dimensional numerical analysis of laminar natural convection with entropy generation in an open trapezoidal cavity filled with water has been carried out. In this investigation, the inclined wall is maintained at isothermal hot temperature while cold water enters into the cavity from its right open boundary and all other walls are assumed to be perfect thermal insulators. Attention is paid on the effects of buoyancy forces on the flow structure and temperature distribution inside the open enclosure. Rayleigh number is the main parameter which changes from 103 to 105 and Prandtl number is fixed at Pr =6.2. Obtained results have been presented in the form of particles trajectories, iso-surfaces of temperature and those of entropy generated as well as the average Nusselt number. It has been found that the flow structure is sensitive to the value of Rayleigh number and that heat transfer increases with increasing this parameter.

Abstract

The effect of adverse climate change is of major concern worldwide and several approaches are being developed to mitigate against anticipated economic and social disaster. Carbon emissions has been identified as a major contributor to the adverse climate change and following the Kyoto protocol , European countries have , through a caucus, effected a market to reward or fine members depending on their compliance position. The commodity for the market is the carbon emission credits. Stochastic models for pricing of options on these credits are considered in this paper. In particular, we determine the price basing on the Normal Inverse Gaussian and the Brownian Motion models. Maximum Likelihood Estimation is applied to determine model parameter estimates in each case. It is shown that the Normal Inverse Gaussian model has a better fit to the data but gives higher prices for a given strike price , compared to the Brownian Motion model

Keywords: Carbon Emission Credit, Brownian Motion, Kyoto Protocol Compliance, Normal Inverse Gaussian Distribution, Fourier Transform, Risk-Neutral Option Pricing.

Abstract

In vacuum nano electronics different electron sources are used. They usually consist of hot or cold zirconia, tungsten, or carbon tips, the latter being in diamond or nanotube form. Electron sources of a special composite of precious metal crystals, which are embedded in a fullerene matrix, were first developed in 1992 at the Research Institute of Deutsche Telekom FTZ in Darmstadt, Germany. With those very high emission current densities were achieved and were brought to applications. Outstanding room temperature conductivities were achieved with these nanogranular composite materials, and are presented here along with a model to explain the measured data,
