There are different types of reactive powder concrete (RPC) and researchers continue to develop better-quality mix designs. This research presents an integrated approach for RPC design. For this purpose, 13 designs were collected according expert opinion laboratory samples tested in study validation the characteristics compressive strength water absorption. The then ranked using simple additive...

(See pages 451–2 for the Photo Quiz) Figure 2. Scalp of the infant, showing crusted erythematous erosion following a ruptured bullae. Figure 1. Scaly, erythematous erosions with collaretes of crust and numerous bullae covering the entire lower limbs of the neonate. Diagnosis: congenital syphilis. The infant's rapid plasma reagin test was reactive at a titer of 1:256 dilutions; a Treponema palli...

A monoclonal antibody (mAb) was prepared against a semipurified preparation of an organ specific neoantigen (OSN) reactive in the leukocyte adherence inhibition (LAI) assay. The mAb (LC20.1) induces a positive LAI response when incubated with leukocytes of normal individuals in the presence of OSN derived from either human colon or lung carcinoma cell lines. Absorption of crude OSN preparations...

The NH2-terminal amino acid sequence of type 12 M protein was determined by automated Edman degradation of a 38-kilodalton polypeptide fragment purified from a limited pepsin digest of intact type 12 streptococci. The sequence of the first 13 amino acid residues of the polypeptide confirmed that predicted by the nucleotide sequence of the mature type 12 M protein. A chemically synthesized pepti...

Quercetin is a typical flavonoid with diverse biological effects, attributable to its free radical scavenging activity. Bioavailability of quercetin aglycone and its glycosides is an important factor for its antioxidant activity in vivo. A severe limitation exists and is imputable to very poor absorption of quercetin when administered orally. To overcome this limitation, development of a value ...
