Recently, we developed a low power consumption and small total capacitance switched-capacitor filter using a single operational amplifier. It is called a semi-parallel cyclic type (SPCT) filter, in which each capacitance is in proportion to the square root of a transfer function coefficient value. In this paper, we propose the SPCT filter using a single unity gain buffer (UGB). It will be refer...

CONCLUSION We observed for the first time the expression of Uteroglobin (UGB) in the nasal mucosa of mice. The results of our study suggest that UGB may play an important role in the regulation of inflammation in allergic rhinitis (AR) as well as in the lower airway allergic inflammations. OBJECTIVES Uteroglobin is a protein secreted by epithelial lining of organs communicating with the exter...

BACKGROUND Dengue fever may present hemorrhages and cavitary effusions as result of exacerbated immune responses. We investigated hydro-alcoholic extracts from leaves (UGL) and bark (UGB) of the medicinal species Uncaria guinanensis with respect to antiviral effects in Dengue virus (DENV) infection and in immunological parameters associated with in vivo physiopathological features. METHODS Ch...

It is the living conditions in the cities that determine the future of our livelihood. “To change life, we must first change space”Henri Lefebvre. Sustainable development is a utopian aspiration for South African cities (especially the case study of the Gauteng City Region), which are currently characterized by unplanned growth and increasing urban sprawl. While the reasons for poor environment...

BACKGROUND/AIMS Data about the efficiency and outcome of therapeutic endoscopic techniques in children with nonvariceal upper gastrointestinal bleeding (UGB) are scarce. We aimed to analyze our experience with endoscopic hemoclip application in children with non-variceal UGB. MATERIALS AND METHODS During a 3-year period, a total of 1715 endoscopies were performed in our pediatric endoscopy un...

Urban growth boundaries (UGBs) play an important role in controlling urban sprawl and protecting natural ecosystems. Traditional methods mainly focus on the heterogeneity of regional resources environment rather than residents’ behavioral activities. However, activities are one most factors influencing spatial form. Fortunately, emergence big data, especially phone signaling provides alternativ...

Prostate cancer commonly metastasizes bones and lymph nodes, but it very rarely spreads to the gastrointestinal tract. However, only five cases of prostate cancer metastatic to the stomach have been previously reported in the literature. We report a case of a 69-year-old man with metastatic prostate cancer who presented with upper gastrointestinal bleeding (UGB) 4 years after the diagnosis. Eso...

This study was designed to model the spatio-temporal pattern of Land Use/Land Cover (LU/LC) indices and its relationship with Surface Temperature (LST) in Ibadan Metropolis from 1988 2018. Four Landsat images metropolis for 1988, 1999, 2013 2018 were used this study. surface temperature values vegetation, open surfaces built-up analysis carried out using ERDAS IMAGINE 9.2 order ascertain areas ...

A fast settling multipath CMOS OTA for high speed switched capacitor applications is presented here. With the basic topology similar to folded-cascode, bandwidth and DC gain of the OTA are enhanced by adding extra paths for signal from input to output. Designed circuit is simulated with HSPICE using level 49 parameters (BSIM 3v3) in 0.35μm standard CMOS technology. DC gain achieved is 56.7dB an...
