This paper evaluated the pozzolanic activity of ceramic sanitary ware (CSW) waste when blended with Portland cement (PC). CSW units were broken, crushed and milled to reduce their particle size. These particles characterized by scanning electron microscopy (SEM-EDX), laser granulometry, X-ray fluorescence (XRF) diffraction tests (XRD), then used replace 0–50 wt.% PC CEM I 42.5R in pastes mortar...

Geoscience data are typically big data, and they are distributed in various agencies and individuals worldwide. Efficient data sharing and interoperability are important for managing and applying geoscience data. The OGC (Open Geospatial Consortium) Catalogue Service for the Web (CSW) is an open interoperability standard for supporting the discovery of geospatial data. In the past, regular OGC ...

Recent advances in Sensor Web geospatial data capture, such as high-resolution satellite imagery and Webready data processing and model technologies, have led to the generation of large amounts of datasets from real-time or near real-time observation and measurement. How to find and retrieve the sensor or data complying with criteria such as specific time, location, and scale has become a bottl...

Latino immigrants in the United States are disproportionally impacted by the HIV epidemic but face barriers to clinic-based testing. We assessed a community-based strategy for rapid HIV testing by conducting "door-to-door" outreaches in apartments with predominately Latino immigrants in Durham, North Carolina, that has experienced an exponential growth in its Latino population. Eligible persons...

Inland saline groundwater is abundant in various areas of the world but is not suitable for traditional agriculture irrigation and is also not suitable for marine aquaculture mainly because of potassium deficiencies. In the present work, we used marbled spinefoot rabbitfish Siganus rivulatus, as a model organism to investigate whether varying levels of aqueous K affect survival and growth, and ...

BACKGROUND Ahmedabad is an industrial city in Gujarat, India. In 2003, the HIV prevalence among commercial sex workers (CSWs) in Ahmedabad reached 13.0%. In response, the Jyoti Sangh HIV prevention programme for CSWs was initiated, which involves outreach, peer education, condom distribution, and free STD clinics. Two surveys were performed among CSWs in 1999 and 2003. This study estimates the ...

BACKGROUND Natriuresis with polyuria is common after aneurysmal subarachnoid hemorrhage (aSAH). Previous studies have shown an increased risk of symptomatic cerebral vasospasm or delayed cerebral ischemia (DCI) in patients with hyponatremia and/or the cerebral salt wasting syndrome (CSW). However, natriuresis may occur in the absence of hyponatremia or hypovolemia and it is not known whether th...

OBJECTIVE To describe the outcome of patient referral at the STD clinic of the University Hospital Rotterdam. To study characteristics of heterosexual index patients and partnerships related to referral outcome. METHODS In 1994, patients with gonorrhoea and chlamydia were referred to public health nurses for interview and patient referral. Referral outcome was classified as "verified" if part...

BACKGROUND llicit sexual behavior by commercial sex workers (CSW) may have a disproportionate impact on the reproductive health of a woman that often leads to cervicitis. This study aimed at examining the cytopathology, patterns, prevalence and burden of cervicitis in CSW in Enugu metropolis, Nigeria. METHODS Cervical smear was collected from the endocervix of about one hundred and eighteen (...
