One of the factors which affects the gas lift performance is specific gravity of a lift gas (or the Molecular weight), which can influence the gas solubility in oil and has a direct effect on the gas lift performance. There are some previous researches which have included the lift gas specific gravity in their modeling, but in none of them, a comprehensive research about the effect of lift gas ...

OpenID has found its usage on the Internet for Web Single Sign-On. Simple Authentication and Security Layer (SASL) and the Generic Security Service Application Program Interface (GSS-API) are application frameworks to generalize authentication. This memo specifies a SASL and GSS-API mechanism for OpenID that allows the integration of existing OpenID Identity Providers with applications using SA...

Mangrove forests are ecosystems located in tidal areas coastal areas, beaches, and small islands. The area of ​​mangrove is decreasing due to the conversion mangrove into fishponds, plantations, timber exploitation. ecosystem rehabilitation activities need be carried out through planting. Avicennia alba a pioneer species that grows swamp habitats on sheltered locations, as well saltier parts co...

A total of 62 strains of Actinomyces pyogenes (previously Corynebacterium pyogenes) were examined by the API 20 Strep system (API System, La Balme Les Grottes, Montalieu-Vercieu, France). The system was shown to be reliable and rapid when the tests were compared with standard identification methods. No confusion occurred with streptococcal profiles in the current API 20 Strep data base.

API 20E and invA PCR were evaluated for the identification of Salmonella enterica isolates from swine farms. API 20E had the highest agreement with other tests at the 99.9% likelihood level. Both tests had 100% sensitivity and 96% specificity compared to 16S rRNA sequencing. Compared to serotyping, both tests had 96% sensitivity; specificity was 86% for API 20E and 79% for invA PCR.

Thermal cracking of heavy oil residues has gained the attention refineries due to increasing need for light fractions, as well its lower value compared fractions. In this paper, thermal process residual crude that product from atmospheric distillation towers in Samawah Refinery was studied order convert into a lighter oil. API gravity and conversion ratio result been adopted indicators accuracy...

Recently, there has seen increasing interest in developing online map services using Google Maps Application Programming Interface (API), Yahoo! Maps API, Microsoft Bing Maps API, Nokia Ovi Maps API, and ESRI ArcGIS API. Application developers utilize Maps API as a platform and combine spatial data from multiple sources to create new customized services – a buzzword commonly called map “mashups...

Of four tested identification systems (API 20E, API Rapid 32 IDE, Micronaut E, and the PCR-based Yersinia enterocolitica Amplification Set), API 20E is still the system of choice for identifying pathogenic Yersinia isolates. It provides the highest sensitivity both at the genus and at the species level and has the best cost-effectiveness correlation.

Arabinose-5-phosphate isomerases (APIs) catalyze the interconversion of d-ribulose-5-phosphate and D-arabinose-5-phosphate, the first step in the biosynthesis of 3-deoxy-D-manno-octulosonic acid (Kdo), an essential component of the lipopolysaccharide in Gram-negative bacteria. Classical APIs, such as Escherichia coli KdsD, contain a sugar isomerase domain and a tandem cystathionine beta-synthas...
