Background: Ceftriaxone is an antibiotic used for treating respiratory,skin,bone and kidney infections. Our purpose was investigating effect of ceftriaxone on testicular tissue. Materials and Methods: 40 mice with 6 weeks old were used in this study. The mice randomly were divided into 2 groups, control- sham and test groups. The test group was subdivided to IP1 and IP2 which received Ceftriaxo...

Thrust chamber cooling system is an important issue in liquid missile systems. In this paper, two more applicable systems, that is, regenerative and radiation cooling systems are studied. Regenerative cooling systems, which are mostly used in high pressure thrust chambers, are normally in two forms, tubular wall structure and double wall structure. Tubular structure has mostly a square form str...

The aim of this study is to optimize performance functions of turbofan engines considering the off-design model of turbofan engine as well as employing multi-objective genetic algorithm. The design variables including high-pressure compressor pressure ratio, low-pressure compressor pressure ratio, fan pressure ratio and bypass ratio are calculated in such a way that the corresponding functions ...

Emissions inventory calculations for airports, using standard emissions inventory reporting methods, are inflated due an assumption of use of maximum takeoff thrust. To enhance the operational life of jet engines and reduce fuel burn, airlines frequently use reduced thrust (i.e. Derated or Flex Temperature thrust) for the takeoff procedure. Without access to internal airline “load sheet” paperw...

In the present study fecundity of Terapon puta was estimated for 47 matured females from the Bay of Bengal, Pondicherry. The fecundity (F) was found to range from 20,002 to 1,23,042 in fishes between 134-219mm Total length(TL) and 30-78 gm weight respectively. The co-efficient of correlation for F/TL (log F = 0.790+1.731 log TL), F/SL (log F = 0.799+1.773 log SL), F/TW (log F = 2.590+0.450 log ...

The body weight and testicular and epididymal parameters of Afar, Long-eared Somali (LES), and Woyto-Guji (WG) breeds of goat were investigated. A total of 405 randomly selected bucks of Afar (n = 135), Long-eared Somali (n = 135), and Woyto-Guji (n = 135) were included in this study. The overall mean scrotal circumference (SC), testicular volume (TV), testicular length (TL), testicular weight ...

Advanced ceramic materials are gradually becoming very important for their superior properties such as high hardness, wear resistance, chemical resistance, and high strength to weight ratio. But machining of advanced ceramic like Al2O3-ceramics is very difficult by any well known and common machining processes. Normally, cleavages and triangular fractures generate when machining of these materi...

Background: In order to improve the evaluation of possible rectal toxicity based on the rectal normal tissue complication probability (NTCP), we consider the fractional dependence of the NTCP on the wall thickness (tW) and rectal displacement (RM). Materials and Methods: The two-dimensional NTCP model (NTCP2D) was developed using radiotherapy plans of ten randomly selected patients with prostat...

The purpose of this paper is to perform the feasibility and performance evaluation of the High-altitude launch technique using high altitude atmospheric Properties to near earth orbits. The current propulsion transportation system from Earth to space has been deemed by many to be expensive, unreliable, and an unnecessarily dangerous means of travel to space. It is suggested in this paper to ana...
