This paper examines the impact of government guaranteed small business loans on economic growth, and whether government guaranteed loans crowd out new businesses financed through the market. OLS estimates indicate a significant and positive relation between the Small Business Administration’s (SBA) guaranteed loans and metropolitan growth between 1993 and 2002. However, endogeneity hinders caus...

OBJECTIVE Subchondral bone attrition (SBA) is defined as flattening or depression of the osseous articular surface. The causes of attrition are unknown, but remodeling processes due to chronic overload that are reflected as bone marrow edema-like lesions (BMLs) on magnetic resonance imaging (MRI) might predispose the subchondral bone to subsequent attrition. The aim of this study was to evaluat...

Two forms of an acidic bromelain proteinase isolated from crude bromelain, an extract from pineapple stem, were found by a two-step FPLC purification procedure. The basic main components were removed by cation exchange chromatography and the breakthrough fraction was further resolved by anion exchange chromatography into 15 protein fractions, only two of which, called SBA/a and SBA/b, were prot...

BACKGROUND Maternal mortality remains unacceptably high in sub-Saharan Africa with 179,000 deaths occurring each year, accounting for 2-thirds of maternal deaths worldwide. Progress in reducing maternal deaths and increasing Skilled Birth Attendant (SBA) use at childbirth has stagnated in Africa. Although several studies demonstrate the important influences of women's status and empowerment on ...

Tuning the interfacial perimeter and structure is crucial to understanding the origin of catalytic performance. This paper describes the design, characterization, and application of CeO2 modified Au@SBA-15 (Au-CeO2@SBA-15) catalysts in selective oxidation of benzyl alcohol. The reaction results showed that Au-CeO2@SBA-15 catalysts exhibited higher catalytic activity compared with Au@SBA-15 and ...

We formally deene the set-based abstraction of any language whose operational semantics can be deened by environment evaluation. The Aiken-Wimmers soft type system precisely corresponds to this set-based abstraction under their operational semantics. The Heintze set-based analysis is precisely this set-based abstraction under a diierent operational semantics. In general, set-based abstraction d...

Cyanide-functionalized mesoporous silica SBA-15 (CN/SBA-15) with pore diameters larger than 6 nm has been prepared by a one-pot synthesis. The structure of CN/SBA-15 is affected by the amount of the functional silane 2-cyanoethyltriethoxysilane (CTES) and the conditions of co-condensation in the acidic aqueous solution of the triblock copolymer Pluronic P123: whereas direct mixing of the silica...

We evaluated alamarBlue as a metabolic indicator in a standardized assay for the measurement of serum bactericidal activity (SBA) to Haemophilus influenzae type b (Hib) using sera containing natural and vaccine-induced anticapsular (polyribosylribitol phosphate) antibodies. SBA assays with a colorimetric and a fluorometric end point in the presence of alamarBlue were developed and compared to a...
