Although microbial communities have varying degrees of exposure to environmental stresses such as chemical pollution, little is known on how these communities respond to environmental disturbances and how past disturbance history affects these community-level responses. To comprehensively understand the effect of organophosphorus insecticide application on microbiota in soils with or without in...

the adsorption study was conducted on three japanese soils with different soil properties to characterize the adsorption pattern of arsenic (as). double tube method was used to find out the effect of soil moisture levels on as adsorption. for this study, besides double tube method, conventional batch method also was used. the as adsorption showed two phase kinetics. an initial and rapid adsorpt...

Heap spraying is a security attack that increases the exploitability of memory corruption errors in type-unsafe applications. In a heap-spraying attack, an attacker coerces an application to allocate many objects containing malicious code in the heap, increasing the success rate of an exploit that jumps to a location within the heap. Because heap layout randomization necessitates new forms of a...

Heap-spraying is an attack technique that exploits memory corruptions in web browsers. A realtime detection of heap-spraying is difficult because of dynamic nature of JavaScript and monitoring overheads. In this paper, we propose a runtime detector of heap-spraying attacks in web browsers. We build a string trace graph by tracing all string objects and string operations in JavaScript. The graph...

Methods We studied 50 patients with infrequent ( 1 episode/month), sustained ( 1 min) palpitations. Before enrollment, patients had a negative initial evaluation, including history, physical examination, and ECG. Patients were randomized either to conventional strategy (24-h Holter recording, a 4-week period of ambulatory ECG monitoring with an external recorder, and electrophysiological study)...

Sugar spraying can cause induced plant resistance. In this study we investigated the effects of sugar spraying on the resistance to western flower thrips, WFT, Frankliniella occidentalis on tomato. We tested three different sugars: sucrose, fructose and glucose, at four concentrations: 0, 1, 10 and 100 ppm, to induce resistance of the cultivated tomato (var. Moneymaker). Bioassays conducted 2 w...

LetM = (M,OM) be a smooth supermanifold with connection ∇ and Batchelor model OM ∼= ΓΛE∗ . From (M,∇) we construct a connection on the total space of the vector bundle E →M . This reduction of∇ is well-defined independently of the isomorphism OM ∼= ΓΛE∗ . It erases information, but however it turns out that the natural identification of supercurves inM (as maps from R1|1 toM) with curves in E r...
