The corrosion inhibition properties of cefradine (CFD) for mild steel corrosion in HCl solution were analysed by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and gravimetric methods. Potentiodynamic polarization study clearly revealed that cefradine acted as mixed type inhibitor. The experimental data showed a frequency distribution and therefore a modelling element with frequency dispersion behaviour, a constant phase element (CPE) has been used. The various thermodynamic parameters of dissolution and adsorption processes were evaluated in order to elaborate adsorption mechanism. Adsorption of inhibitor obeyed Langmuir adsorption isotherm model. © 2014 by ESG.

Summary: The Tasman Glacier is one of many freshwater-terminating glaciers located in the Aoraki/Mt Cook National Park that has retreated significantly since the mid-20th century. Although there have been several observations made of the glacier since the formation of Tasman Lake and the following rapid retreat, the glacier entered a period of rapid terminus disintegration and retreat since c. AD 2000. The retreat of Tasman Glacier between 2000 and 2008 has occurred in two distinct periods: an initial period of relatively slow retreat prior to 2006, followed by a secondary period of rapid retreat between 2006 and 2008. Terminus full width retreat for the period 2000-2006 occurred at a rate of 54 m a-1, accelerating to 144 m a-1 during 2006-2008. During the period 2000-2006, the controlling process of ice loss at the terminus was iceberg calving resulting from thermal undercutting. In contrast, the retreat between 2006 and 2008 was probably controlled by buoyancy-driven iceberg calving caused by decreased overburden pressure as a result of supraglacial pond growth. As a result, the surface area of Tasman Lake has increased by 86% over the period 2000-2008, with lake volume increasing by 284% between 1995 and 2008. Currently, the volume of Tasman Lake is 510 × 106 m3. It will increase dramatically in near future as the lake expands into deeper water.

This research focused on the impacts of discourses on images and, in turn, on the impact of these images on actions. Specifically, on the restoration actions conditioned by an image of secularization facing an autonomy discourse. For this purpose, analysis categories were defined: discourses, images and actions. Subsequently, discourse types were identified: heteronomy and autonomy; then, the type of images: worship and secular. And finally, the types of actions: restoration and new works. As a result of the analysis, a power relationship between discourses and images was established, projected by people with some type of power, which further inspired restoration actions, and the discourses and images projected by those affected by such actions.

Current Opinion in HIV and AIDS | Year: 2015

Purpose of review: Detection of early HIV infections (EHIs), including acute HIV infection (AHI), is important for individual health, prevention of HIV transmission, and measurement of HIV incidence. We describe markers of EHI, diagnostic strategies for detecting these markers, and ways to incorporate these strategies into diagnostic and HIV incidence algorithms.Recent findings: For individual diagnosis in the USA and Europe, laboratory-based diagnostic algorithms increasingly incorporate fourth-generation HIV antigen tests, allowing for earlier detection. In some sub-Saharan African settings, symptom-based screening is being explored to identify subsets of persons at high risk for AHI. Point-of-care diagnostics designed for AHI detection are in the pipeline and, if validated, represent an opportunity for real-time AHI diagnosis. At the population level, multiassay algorithms are promising new strategies for estimating HIV incidence on the basis of several assays applied to cross-sectional samples. These algorithms can be developed to optimize performance, in addition to cost and logistical considerations.Summary: There are important recent advances in detection of EHIs at the individual and population levels. Applying optimal combinations of tests in diagnostic and HIV incidence algorithms is urgently needed to support the multiple goals derived from enhanced detection and discrimination of EHIs. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins.

The optimal combination of size and shape parameters for classifying structural elements with the lowest percentage error is determined. For this purpose, logical sequences and a series of micrographs of tissues of the pumpkin Cucurbita pepo L. were used to identify and manually classify structural elements into three different classes: cells, intercellular spaces and unrecognizable elements. From each element, eight parameters of size and shape (area, equivalent diameter, major axis length, minor axis length, perimeter, roundness, elongation and compaction) were determined, and a logical sequence was developed to determine the combination of parameters that generated the lowest error in the classification of the microstructural elements by comparison with manual classification. It was found by this process that the minimum error rate was 12.7%, using the parameters of major axis, minor axis, perimeter and roundness.
