in this study 74 stray dogs including 39 females and 35 males with cooperation of dog killing team of municipality were killed, examined macroscopically and microscopically in kerman city from 1992 to 1993. taenia hydatigena was the most prevalent helminth observed in 57 dogs (77%), dipylidium caninum in 13 dogs (17.6%), echinococcus granulosus in 5 dogs (6.8%) and toxocara canis in one dog (1....

As a result of various communications from S. Han, we conclude that our criticism of the Dresselhaus et al. Letter [1] is incorrect. Our calculation of the change in free energy DF was obtained by first calculating the voltage sV d independent electrostatic energy part DE and next adding to it the term for the work done, which is V dependent. We compared our DE result with what we thought was t...

Power transformers represent the largest portion of capital investment in transmission and distribution substations. In addition, power transformer outages have a considerable economic impact on the operation of an electrical network. One of the most important parameters’ governing a transformer’s life expectancy is the hot-spot temperature value. Due to under estimation of stray losses in powe...

The development of SiC and GaN power devices to achieve high-speed switching operations in converter circuits is underway. stray inductance caused by the bus bar geometries between DC capacitors influences circuits, such as surge voltages losses. Therefore, evaluation parasitic parameters essential designing circuits. Currently, that consider various are calculated using finite element analysis...

Leptospira reactivity in stray and household dogs in Campeche as well as associated risk factors to the seropositivity in household dogs have been herein determined. The survey included 323 dogs, 142 of which were stray dogs and 181 household dogs. Nine Leptospira interrogans serovars were tested by the microagglutination test. Reactivity was 21.3 % (69/323), 17.2 % corresponded to household do...

Abstract: In order to analyze the distribution rules and influence of stray current on subway rectangulartunneland subway Shield tunnel, threedimensional models were built separately. By changing the values of carry-current, ansys was used toanalyzeunder different geological conditions.Simulations show that the potential attenuation is nonlinear from the subway tunnel to the surrounding undergr...

in the present study 6500 stray dogs were killed in 1993-4 to initiate a preliminary control program in rural and urban areas of the city of kerman. 391 dogs including 169 (43.12%) females and 222 (56.8%) males were selected randomly, dissected and examined for echinococcus granulosus and microscopically. the overall prevalence rate was 7.4%. the younger dogs were more susceptible to infection ...

Formation of stray grain defects particularly around re-entrant features of the turbine blade airfoils is one of the major problems in directional and single crystal solidification processes. In this work, directional solidification tests of the GTD-111 Ni-based superalloy were conducted at different withdrawal velocities of 3, 6 and 9 mm.min-1 using various stepped cylindrical and cubic design...

In high power converter design, low-inductance busbar connecting DC capacitors and power devices is the main concern to improve the quality of the whole power electronics system. This paper analyzes the impact of layernumber on the stray inductance of busbar taking a subway traction converter as example. The method of partial element equivalent circuit and the Q3D software are used to extract t...

This paper clarifies the effect of gate inductance $L_{g}$ inside IGBT modules on voltage spikes when a digital driver is employed. Three with different were fabricated to implement double pulse tests by conventional driving and contr...
