history means research on events that at a certain time have been taken into account, observed and kept in mind by researchers and has built a structure of the story about same events. reality is greater than history and in terms of number exceeds it highly. this leads into identity generating. in this sense, identity is a criterion that historical event can be studied based on it. as we speak ...

The ability to produce three-dimensional physical property models of the subsurface from surface geophysical data, coupled with an increasing need to explore for minerals in concealed terranes, results in geophysical inversions providing more significant information to the exploration team. We examine the role that geophysical inversion can play in an integrated mineral exploration program, and...

 Events leading up to the release of toxic chemicals in the processing plants are one of the main hazards of chemical industries that can endanger employees and also people in neighborhood. In this study, DOW's Chemical Exposure Index (CEI) is used to determine hazard distances of possible toxic chemical releases in one of the South Pars gas refineries. To...

Oil and gas well drilling activities are associated with numerous hazards which have the potential to cause injury or harm for people, property and the environment. These hazards are also a threat for the reputation of drilling companies. To prevent accidents and undesired events in drilling operations it is essential to identify, evaluate, assess and control the attendant risks. In this work, ...

Evaluation of volcanic hazards typically focusses on single eruptive centres or spatially restricted areas, such as fields. Expanding hazard assessments across wide regions (e.g., large sections a continental margin) has rarely been attempted, due to the complexity integrating temporal and spatial variability in tectonic magmatic processes. In this study, we investigate new approaches quantify ...

Although sperm are typically thought to be small, tadpole-like cells produced in vast quantities, sperm size, form and number all vary tremendously across species. Sperm form ranges from amoeboid or discoid to multiflagellate elongated structures [1]. Even within the more familiar uniflagellate spermatozoa, length varies by several orders of magnitude, from the tiny 28μm long porcupine sperm to...

The previous detection of two species related to the nonpolar molecule cyanogen (NCCN), its protonated form (NCCNH + ) and one metastable isomer (CNCN), in cold dense clouds supported hypothesis that dicyanopolyynes are abundant space. Here we report first identification space NC 4 NH . This cation is N, which second member series after NCCN. was based on observation six harmonically lines with...

In the course of glacier retreat, new glacier lakes can develop. As such lakes can be a source of natural hazards, strategies for predicting future glacier lake formation are important for an early planning of safety measures. In this article, a multi-level strategy for the identification of overdeepened parts of the glacier beds and, hence, sites with potential future lake formation, is presen...

Electronic health records (EHRs) have potential quality and safety benefits. However, reports of EHR-related safety hazards are now emerging. The Office of the National Coordinator for Health Information Technology recently sponsored an Institute of Medicine committee to evaluate how health information technology use affects patient safety. In this article, we propose the creation of a national...
