INTRODUCTION Polymorphic light eruption (PLE) is a common idiopathic photodermatosis that typically presents with pruritic papular or papulovesicular lesions on sun-exposed skin between spring and autumn. In many subjects PLE is mild, and can usually be prevented by the use of broad-spectrum topical sunscreens and a gradual increase in sunlight exposure. However, in some individuals, sunlight e...

or metabolites. The presence of anti-neural antibodies in patients with pns has led to the suggestion that the associated neurologic symptoms are a result of antibody-induced inflammatory reactions3. Because of the infrequent incidence of ple, there is a paucity of literature discussing its diagnosis and management. Here, we describe a case of ple in a male patient, and we discuss the syndrome’...

Personal Learning Environments (PLEs) are attracting increasing interest in the e-learning domain. However, the term Personal Learning Environment is used in a variety of different ways in the field. This paper firstly draws distinctions between the term PLE and similar terms. It then discusses the dimensions which characterise current conceptions of PLEs, thereby defining a space of PLEs. Thre...

The growing importance of media and media-like codes ha s caused general-purpose processors too incorporate SIMD-like extensions, such as MMX, SSE, and Alt iVec. While these media extensions do improve performance , significant parallelism in these codes remains u nexploited. In this paper, we propose and evaluate a programmable loopp engine (PLE for short) that executes media codes and kernels...

Counter to commonly accepted views observations of interactive seeking behavior in different search environments show that a user behaves precisely in the same manner in traditional IR systems and on the Web. Unmediated users resort to the same tactics of successive search based on the principle of least effort (PLE). On the contrary, an intermediary in classical mediated searching follows the ...

A comparison of analysis in evaluating the hepatoprotective action of ethanolic extract of M. azedarach (MAE) and P. longum (PLE) with their combination biherbal extract (BHE) against carbon tetrachloride (CCl4) induced hepatic damage is reported in albino rats. There was a marked elevation of serum marker enzyme levels in CCl4 treated rats, which were restored towards normalization in the drug...

Web 2.0 integration requires a high level of learner-centered skills to create a personal learning environment (PLE). The pedagogical capability of Web 2.0 could support and promote self-regulated learning (SRL) by enabling the constructions of PLEs. This study investigated how will each of the six aspects of self-regulated online learning (i.e., environment structuring, goal setting, time mana...

Intelligent tutoring systems (ITSs) provide students with a one-on-one tutor, allowing them to work at their own pace, and helping them to focus on their weaker areas. The RUR– Python Learning Environment (RUR-PLE), a game-like virtual environment to help students learn to program, provides an interface for students to write their own Python code and visualize the code execution (Roberge 2005)....

The new maximum contaminant level (MCL) of 10 microg/L for arsenic in the US drinking water will take effect on January 22, 2006. The compliance cost is estimated to be approximately dollar 600 million per year using current treatment technologies. This research aims to develop an innovative ion exchange process that may help water utilities comply with the new MCL in a more cost-effective mann...

Polymorphic light eruption (PLE), with an overall prevalence of 10-20%, is mainly provoked by ultraviolet A (UVA) (320-400 nm) and to a lesser degree by UVB (280-320 nm). The most effective prophylaxis of PLE, application of UV protection clothing, is not feasible for all sun-exposed areas of the skin and UV-hardening is time-consuming and may be associated with side-effects. Most sunscreens pr...
