Alkaloids are aromatic hydrocarbons with nitrogen as heteroelements in the ring structure that responsible for bonding metal surface and help to reduce corrosion of metals such mild steel (MS) an acidic medium. In this study, alkaloid Rhynchostylis retusa (RR) was extracted by solvent extraction method confirmed chemical test well FTIR spectroscopic test. Extracted alkaloids were tested green i...

dans cet article, l'auteur tudie la creation d'une voie ferre interurbaine, de la banlieue ou urbaine, et essaie de d6terminer le nombre optimal de stations pour une longueur donnee de la ligne; compte tenue d'une repartion du trafic, ie long de la ligne en question qui est suppose etre connue. le critere d'optimalisation est le temps total perdu par l'ensemble des usag...

dans cet article i' intervalle entre deux trains successifs a ete etudie en fonction de leur vitesses dans deux cas differents. dans ie premier cas ,on suppose que la vitesse des deux trains a une valeur constante, et on etudie les variations de l'intervalle minimum en fonction de la vitesse on determine la vitesse optimale et on etudie les variations de l'intervalle minimum en f...

Abstract Synthesis and inhibition effectiveness of (2E)-2-(furan-2-ylmethylidene) hydrazine carbothioamide (FMHC) as an inhibitor for corrosion mild steel in 0.5 M H 2 SO 4 is reported. Experiments were conducted at various temperatures (303–323 K) by adopting potentiodynamic polarization electrochemical impedance spectroscopy. Readings obtained demonstrated that percentage efficiency (% IE) im...

background: molecules expressed on the surface of infected erythrocytes (ie) with plasmodium falci-parum play important roles in malaria pathogenesis and immune evasion. some of these molecules are specific adhesive ligands mediating adhesion of ie to the vascular endothelium. in the current study, the antigens exposed on the surface of ie with different isolates and various binding subpopulati...

more commonly among men in their 50s. Back pain (19.1%) was the most common rheumatic manifestation. Myalgia (15.5%) was also frequently observed, as was arthra l gia without art h ritis (10%). Pe ri p h e ra l arthritis (13.6%) was also present, but generally as monoarthritis. In contrast, sacroiliitis was only observed in a single patient. This patient was a man in his early twenties, who had...

Brainstem-mediated antinociceptive inhibitory reflexes of the temporalis muscle were investigated in 82 patients (47 F, 35 M, mean age 28.3 years, SD 9.4) with acute posttraumatic headache (PH) following whiplash injury but without neurological deficits, bone injury of the cervical spine or a combined direct head trauma on average 5 days after the acceleration trauma. Latencies and durations of...

Aminoglycoside 2″-phosphotransferases are the major aminoglycoside-modifying enzymes in clinical isolates of enterococci and staphylococci. We describe a novel aminoglycoside 2″-phosphotransferase from the Gram-negative pathogen Campylobacter jejuni, which shares 78% amino acid sequence identity with the APH(2″)-Ia domain of the bifunctional aminoglycoside-modifying enzyme aminoglycoside (6') a...

In the background where there are many factors affecting Japanese families such as decrease of children, change family structures, gender concept, etc., "family'' has become a noticeable issue attracting much attention nowadays. The type traditional named "IE'' was officially regulated in law during Meiji period. After war, legal status eliminated; however, reality, still remains popular. fact,...
