the soltan dam on the river soltan, a branch of tine river, is located about 19 km of mateur city in the northeast of tunisia. the dam is now under study and will be constructed in 2017. the soltan dam has been designed as an earth fill dam with homogeneous materials. the dam and its associated concrete structures are mainly founded on marl, shale and shale of lower miocene age, sandstone of th...

ONE of the most serious handicaps to poultry raising in the Southwestern States is the fowl tick, or blue bug {Argm rmneahis). It is a persistent bloodsucker, and its presence in a poultry house in considerable numbers results in weakened stock, fewer eggs, and emaciation and not infrequently death of some of the fowls. A form of paralysis associated with this tick also afl'ects many fowls, som...

The rapid discovery of novel viruses using next generation sequencing (NGS) technologies including DNA-Seq and RNA-Seq, has greatly expanded our understanding of viral diversity in recent years. The timely identification of novel viruses using NGS technologies is also important for us to control emerging infectious diseases caused by novel viruses. In this study, we identified a novel duck coro...

The phenomena of natural and acquired resistance to transplanted chicken tumors strikingly resemble those observed in the case of transplanted mammalian growths; and no more than those do they suggest that the tumors have an extrinsic cause. That there may exist in fowls implanted with a chicken tumor a resistance directed against the tumor-causing agent distinct from the resistance manifested ...

seepage analysis through earth dams is employed to determine the water loss. moreover, as the magnitude of pore pressure in dam body is calculated using seepage analysis, this analysis plays an important role on the stability analysis in these types of structures. as the hydraulic conductivity of the earth dam materials, is considered as one of the effective parameters on the magnitude of seepa...

This paper reports estimates of correlated genetic change in reproductive performance of purebred gilts producing two-way cross litters and purebred sows producing purebred litters as well as postweaning performance of two-way cross and purebred pigs produced during reciprocal recurrent selection (RRS) between Line 8 (Duroc) and Line 9 (Beltsville No. 1) for 21-d litter weight production of cro...
