The effects of the human and bovine LSF (derived from sera) as well as their purified fractions were studied on murine lymphocytes reactions indicated by blast transformation (BT) assay, mixed lymphocyte culture (MLC) and IgG synthesis. The results indicated that bovine lipid suppressor factor (LSF) has significant immunosuppressive activity on lymphocytes proliferation both in BT and MLC ...

A new text-independent speaker identification (SI) system is proposed. This system utilizes the line spectral frequencies (LSFs) as alternative feature set for capturing the speaker characteristics. The boundary and ordering properties of the LSFs are considered and the LSF are transformed to the differential LSF (DLSF) space. Since the dynamic information is useful for speaker recognition, we ...

Reducethese impacts, concrete is some degree subbed among blend Silica Fume (SF) and Fly Ash (FA) sand by Quarry Dust (QD) with addition steel fibre. This paper centered on...

A sustainable economy can be achieved only by assessing processes finalized to optimize the use of resources. Waste can be a relevant source of energy thanks to energy-from-waste processes. Concerns regarding the toxic fly ashes can be solved by transforming them into resource as recycled materials. The commitment to recycle is driven by the need to conserve natural resources, reduce imports of...

The use of date palm fiber (DPF) as natural in concrete and mortar continues to gain acceptability due its low-cost availability. However, the main disadvantage DPF cement-based composites is that it reduces compressive strength increases porosity composite. Hence, for be efficiently used concrete, negative effects must counteracted. Therefore, this study, silica fume was employed supplementary...
