Traditionally, morphological features are used for their taxonomy and discrimination. However, these methods fail to provide an accurate for discrimination and authentication, suggesting the use of other method inevitable. In this study, RAPD method was used for genotypes identification and characterization of five most socio-economical Palestinian thymes: Thymus syriacus, Thymus fruticosus, Thymus incanus, Thymus majorana, and Thymus capitatus. Eight out of ten decamer primers were tested for their ability to generate polymorphism from selected thyme species using RAPD-PCR, and the obtained data were analyzed. The primers (OPD-19, OPH-02 and OPAN-08) were generated 78.6% average polymorphism across five studied Thyme species. Pairwise similarity analysis revealed banding patterns between the studied plant species ranged from 0.18 to 0.67. By this study, genetic diversities of studied five Palestinian Thyme species were ascertained successfully using RAPD markers, concluding that it could be useful tools for identifying Thymes species in any putative breeding programs that will be carried in the country. 2014-09-08T00:00:00Z https://scholar.ptuk.edu.ps/handle/123456789/131 Title: Design and Construction of a Biogas Burner Authors: OlubiyiObada, David; Iheanyichukwu Obi, Anthony; Dauda, Muhammad; OlukayodeAnafi, Fatai Abstract: This paper details the design and fabrication of a burner system, operating on biogas,for use in remote or rural regions of developing countries such as Nigeria. A desirable use for such a system in these areas is domestic cooking, and the burner has been designed with this need in mind, focusing on characteristics such as simplicity, cost effectiveness, efficiency and safety. Mild steel, brass and galvanized pipe sourced locally were selected for the construction. An empirical version of Bernoulli’s theorem was used to derive the flow rate of gas. The different components of the burner design were shown. Also discussed are the modifications necessary to meet the requirements of stable flame for the burner and the testing involved in determining the performance of the burner system. 2014-09-23T00:00:00Z https://scholar.ptuk.edu.ps/handle/123456789/130 Title: Bit Error Rate Analysis of Mobile Ad Hoc Networks over η − µ Fading Channels Authors: Ghareeb, Ibrahim; Atiani, Amani Abstract: In this paper the performance analysis of Mobile ad hoc networks (MANETs) is conducted for a differential QPSK (DQPSK) signals with post-detection equal gain combining (EGC) receiver operating over additive white Gaussian noise (AWGN) as well as for slow frequency nonselective η − µ fading channels, in which the diversity branches can have unequal signal-to-noise ratios (SNRs) as well as different severity parameters. The average bit error probability (ABEP) is evaluated using MGF-based approach. The average BER per multi-hop route of MANETs for this communication is studied. 2014-09-14T00:00:00Z https://scholar.ptuk.edu.ps/handle/123456789/129 Title: Development of a Manually Operated Guillotine Cutter Authors: MomohBello, Omiogbemi Ibrahim; DanielOmomoh, Itsisor; Egwakhide, Oaikhinan Patrick; Olubiyi, Obada David; Vincent, ChiraChike Abstract: A manually operated foot leverage pedal with adjustable blades guillotine cutter was designed and constructed using locally available materials. This machine was designed to shear variety of materials with various thicknesses and sizes depending on the cutting blade capacity and the shearing angle, which cuts the materials with minimal waste and without the formation of chips and bending of the material. The machine is foot powered. It works by first clamping the material with a ram. A moving blade then comes down across a fixed blade to shear the material. The moving blade was inclined at 0.5°, this angle is called the rake angle, to keep the material from becoming wedged between the blades. Test carried out on mild steel shows that the machine is capable of shearing the metal sheet with maximum thickness of 0.5mm. 2014-09-08T00:00:00Z
