Mastitis in One Humped She-Camels (Camelus dromedarius) in Jordan
Azmi D. Hawari,Dhia S. Hassawi
Journal of Biological Sciences , 2008,
Abstract: This study was conducted to establish data on mastitis in she-camels in Jordan. Milk samples were collected from 90 dromedary camels in south province of Jordan. California Mastitis Test (CMT) gave results with 70 milk samples; 42 samples (60%) showed positive CMT. Infection with some bacterial species was associated with positive CMT. About 21% of the camels revealed clinical signs of mastitis. The highest percentage of bacterial count, which range from 3.0x102 to <3.0x103 cfu mL-1, was founded in the milk samples. The most predominant bacterial isolates were Micrococcus spp., Staphylococcus aureus, Streptococcus spp. and Corynebacterium spp. Gentamycin, Ampicillin and Tetracycline were the most effective antimicrobial agents against the bacterial isolates.
The Effect of Fat Supplementation in Shami Goat Diets on Milk Production and Composition, Does Body Weight and Growth Performance of Their Suckling Kids
Fawzi M. AL-Dabbas,Azmi D. Hawari
Pakistan Journal of Biological Sciences , 2011,
Abstract: The aim of this study was to evaluate the effect of feeding a dry fat source to Shami does on their milk production and composition, body weight change, weaning weight and average daily gain of their suckling kids. For this purpose we used thirty two multiparous Shami does weighing (47.431.38 kg) and randomly assigned into four dietary treatments in a Completely Randomized Design (CRD) set. Does were housed with their suckling kids and fed one of four isonitrogenous total mixed rations containing 0, 2, 3 or 4% of dry fat. Milk production and milk fat content were higher (p<0.05) for fat treated does, with no differences between 2% fat level and control group while there was no differences among groups in milk protein content. Final body weight of does was not affected by fat supplementation while body weight changes were higher (p=0.05) for fat treated groups. Weaning weight and average daily gain of suckling kids were increased (p=0.05) for fat treated does, with no differences between 2% fat level and control group. It is concluded that supplemental fat to does rations at 3 or 4% during their postpartum period can improve their milk production and milk fat content, as well as body weight change of does, weaning weight and average daily gain of suckling kids, without any effect on their milk protein content.
Isolation and Identification of Mannheimia haemolytica and Pasteurella multocida in Sheep and Goats using Biochemical Tests and Random Amplified Polymorphic DNA (RAPD) Analysis
A.D. Hawari,D.S. Hassawi,M. Sweiss
Journal of Biological Sciences , 2008,
Abstract: The aims of this study were to isolate the M. haemolytica and P. multocida from sheep and goats of Jordan and to identify these bacteria by using biochemical tests and molecular technique. One hundred and ninety six samples were collected from nasal and throat of sheep and goats of two regions (Middle and Northern) in Jordan. The results of the biochemical tests and API 20 E kits identified 50 isolates of Pasteurella multocida and 5 isolates of Mannheimia haemolytica. The identification of these isolates was confirmed by polymerase chain reaction (PCR) technique using PMOut primers for P. multocida and PHSSA primers for M. haemolytica and by random amplified polymorphic DNA (RAPD) using the random primer (OPA-11). Fourteen RAPD profiles were found in P. multocida and 2 profiles were found in M. haemolyitca. The results of this study indicated that identification of P. multocida and M. haemolytica by RAPD analysis was in accordance with those of biochemical tests and using of more than one RAPD primers could improve the identification of the isolates.
Transverse Momentum Distributions at the LHC and Tsallis Thermodynamics
M. D. Azmi,J. Cleymans
Physics , 2013,
Abstract: An overview is presented of transverse momentum distributions of particles at the LHC using the Tsallis distribution. The use of a thermodynamically consistent form of this distribution leads to an excellent description of charged and identified particles. The values of the Tsallis parameter q are truly remarkably consistent.
The Tsallis Distribution at Large Transverse Momenta
M. D. Azmi,J. Cleymans
Physics , 2015, DOI: 10.1140/epjc/s10052-015-3629-9
Abstract: Fits to the transverse momentum distributions of charged particles produced in p - p collisions at LHC energies based on the Tsallis distribution have been shown to work over 14 orders of magnitude. Two versions of the Tsallis distribution are compared and discussed, the thermodynamically consistent version leads to a temperature of T = 74 +/- 13 MeV at the highest beam energy, a result which is in agreement with previous analyses done with lower transverse momentum data.
Transverse Momentum Distributions in p-Pb collisions and Tsallis Thermodynamics
M. D. Azmi,J. Cleymans
Physics , 2013,
Abstract: The transverse momentum distributions of charged particles in p-Pb collisions as sqrt{s_{NN}} = 5.02 TeV measured by the ALICE collaboration are fitted using Tsallis statistics. The use of a thermodynamically consistent form of this distribution leads to an excellent description of the transverse momentum distributions for all rapidity intervals. The values of the Tsallis parameter q, the temperature T and the radius R of the system do not change within the measured pseudorapidity intervall.
Failure monitoring of E-glass/vinylester composites using fiber grating acoustic sensor
A. I. Azmi,Raju,G. D. Peng
Photonic Sensors , 2013, DOI: 10.1007/s13320-012-0076-1
Abstract: This paper reports an application of an optical fiber sensor in a continuous and in situ failure testing of an E-glass/vinylester top hat stiffener (THS). The sensor head was constructed from a compact phase-shifted fiber Bragg grating (PS-FBG). The narrow transmission channel of the PS-FBG is highly sensitive to small perturbation, hence suitable to be used in acoustic emission (AE) assessment technique. The progressive failure of THS was tested under transverse loading to experimentally simulate the actual loading in practice. Our experimental tests have demonstrated, in good agreement with the commercial piezoelectric sensors, that the important failures information of the THS was successfully recorded by the simple intensity-type PS-FBG sensor.
Gamma Dose Rate Measurements in Kuwait Using a Car-Borne GPS Integrated Dosimetric System  [PDF]
Darwish Al-Azmi
World Journal of Nuclear Science and Technology (WJNST) , 2014, DOI: 10.4236/wjnst.2014.43021
A mobile system comprising of a Geiger-Muller (GM) dosimeter connected with a smart phone was used for ambient gamma dose rate survey within the districts and on the roads within the state of Kuwait. While the dosimeter provides data on gamma dose rates, the smart phone provides the GPS navigation information and saves the data for subsequent analysis and mapping. The survey covered a total distance of about 2300 km within the country and 3117 data points were recorded to show the dose rate distribution on the map of Kuwait. The results show that the ambient dose rates in Kuwait range from 40 to 180 nSv.h-1 with a mean value of 103 nSv.h-1. The dosimetric system described has good potential as a tool for determining baseline background radiation dose rates in an area.

Circuits and Systems (CS) , 2013, DOI: 10.4236/cs.2013.41009

Electrical transformers are vital components found virtually in most power-operated equipments. These transformers spontaneously radiate heat in both operation and steady-state mode. Should this thermal radiation inherent in transformers rises above allowable threshold a reduction in efficiency of operation occurs. In addition, this could cause other components in the system to malfunction. The aim of this work is to detect the remote causes of this undesirable thermal rise in transformers such as oil distribution transformers and ways to control this prevailing thermal problem. Oil transformers consist of these components: windings usually made of copper or aluminum conductor, the core normally made of silicon steel, the heat radiators, and the dielectric materials such as transformer oil, cellulose insulators and other peripherals. The Resistor-Inductor-Capacitor Thermal Network (RLCTN) model at architectural level identifies with these components to have ensemble operational mode as oil transformer. The Inductor represents the windings, the Resistor representing the core and the Capacitor represents the dielectrics. Thermography of transformer under various loading conditions was analyzed base on Infrared thermal gradient. Mathematical, experimental, and simulation results gotten through RLCTN with respect to time and thermal image analysis proved that the capacitance of the dielectric is inversely proportional to the thermal rise.
