the pharmacokinetics of cefpirome was investigated in buffalo calves following its single intramuscular (im) administration (10 mg). the peak plasma concentration of cefpirome at 30 min was 9.0 ± 0.5 μg.ml-1, which declined to 0.2 ± 0.1 μg.ml -1 at 24 hrs. the absorption half-life (t1/2ka) and elimination half-life (t1/2 β) were 0.19 ± 0.03 hr and 2.39 ± 0.05 hr, respectively. the area under th...

Cold region covers over 50% all the world. As an indispensable part of project, concrete is greatly affected by temperature during curing process. In this paper, through orthogonal experiment design, we studied mixing temperature, steel fiber, and water reducing agent dosage on mixture slump; influence agent, accelerating content compressive strength concrete; final microstructure scanning elec...

The effect of the degree of polymer branching on retention and drainage performance of flocculated kraft pulp fiber suspensions containing precipitated calcium carbonate (PCC) was investigated and has been correlated with flocs properties obtained by light diffraction scattering (LDS). The results show that polymers of medium charge density are more adequate to be used as retention aids since l...

As a vibration- free concrete, self- compacting concrete (SCC) can be easily used in the absence of consolidation, therefore; it is a good option for repairing and retrofitting concrete structures. The quality of repair layer is highly effective on a successful repair. Accordingly, in this study, factors affecting the quality of fiber-reinforced self-compacting concrete repair layer, including ...

Bio-absorbent palm fiber was applied for removal of cationic violet methyl dye from water solution. For this purpose, a solid phase extraction method combined with the artificial neural network (ANN) was used for preconcentration and determination of removal level of violet methyl dye. This method is influenced by factors such as pH, the contact time, the rotation speed, and the adsorbent dosag...

This paper puts forward a novel non-ionic augmentation system, namely, gelation of native starch in the presence of borax and papermaking fibers. Native starch was blended with high concentration pulp and auxiliary agents. After pasting, the starch gel adhered onto fiber surfaces. However, an excess dosage of agents led to a rigid structure and poor gel strength. Starch became gelatinized and t...

The paper focuses on the introduction of fiber optics, a fusion of science and engineering and describes the materials generally used for its construction along with the procedure used to design the fibers. It gives an idea of the materials used for the construction along with the pros and cons associated with them and various factors governing the emission of ultraviolet, infrared or visible r...

Postweaning diarrhea (PWD) in pigs is a leading cause of economic loss in pork production worldwide. The current practice of using antibiotics and zinc to treat PWD is unsustainable due to the potential of antibiotic resistance and ecological disturbance, and novel methods are required. In this study, an in vitro model was used to test the possibility of producing prebiotic fiber in situ in the...
