Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...

Phenotypic and molecular characterization of multiple antibiotic resistant Gram-negative bacteria in urine samples pregnant women Mother Child Hospital, Nigeria was reported. In the study, 407 apparently healthy were recruited. Structured questionnaire administered to patients obtain their socio-demographic information medical history. Urine collected, processed analysed using standard microbio...

This paper focuses on interpreting the major conceptual features of California’s Academic Performance Index (API) as a coherent set of statistical procedures. To facilitate a characterization of its statistical properties, we first cast the index as a simple weighted average of the subjective worth of students’ normative performance and present its estimation in the form of a linear model. In t...

Determination of the enzymatic profile of 41 Cryptococcus neoformans strains, 20 isolated from AIDS patients and 21 from bird droppings, was performed by using the API-ZYM commercial kit system (Bio-Mérieux, France), which tests 19 different kinds of enzymes. All the strains showed positive enzymatic activity to the esterase (C4) (n. 3). On the contrary, alkaline phosphatase (n. 2), cystine ary...

Three genetically distinct groups of Candida parapsilosis were detected among clinical isolates. These were distinguishable on the basis of isoenzyme profiles and DNA sequences of internally transcribed spacer (ITS) sequences flanking the 5.8S RNA gene. In an investigation of 45 strains, including 32 clinical isolates from Texas, C. parapsilosis group I composed the majority of the common clini...

Fifty-five isolates of coagulase-negative staphylococci from blood were identified four times each by using the API Staph-Ident (API-SI) system to determine the identification reproducibility of the system. Identifications were determined by using both Version 1 and Version 2 of the API-SI Profile Index. The 75 to 100% reproducibility levels, including reproducible nonidentifications, were 98.2...

Antimicrobial resistance (AMR) of foodborne pathogens is public health concern, especially in developing countries such as Zambia. This study was undertaken to determine the antimicrobial profiles Escherichia coli (E. coli) and Salmonella isolated from retail broiler chicken carcasses purchased open markets supermarkets A total 189 E. five isolates were isolated. Identification confirmation don...

Most applications need to invoke some Application Programming Interfaces (APIs), e.g. JDK (Java Development Kit) API. When invoking those APIs, applications must follow some API constraints. Violation of these constraints will lead to some severe program defects. To detect this kind of defects, lots of static and dynamic approaches are explored, using formally described API constraints. While m...

Mode analysis and dispersion relations are the basic characteristics for cylindrical dielectric waveguides. The waveguide configuration is based on geometry and on the index profile. The nominal index profile is the basis for the calculation of the field profile and the dispersion relations. However, a strong motivation exists for the evaluation of a real index profile. The modern index profile...
