In Morocco, the extraction of beach and dune sand for use in the construction industry is destroying significant portions of the nation’s natural heritage. The authors of this report have significant experience in evaluating coastal mining worldwide. We believe that the coastal sand mining operations that we witnessed in Morocco are the world’s largest. In addition, the environmental impacts of...

What can the enlightened sectors of the international community do to prevent and halt the proliferation of genocides and massive human rights violations around the planet? We evade the obvious, albeit costliest answer—to arrest them before, or at least while they are happening, by any means necessary: to stop them by stopping them. Instead, we focus on actions after the fact. One method, which...

This paper reports on the results of a security analysis of the European Railway Traffic Management System (ERTMS) specifications. ERTMS is designed to be fail-safe and the general philosophy of ‘if in doubt, stop the train’ makes it difficult to engineer a train accident. However, it is possible to exploit the fail-safe behaviour of ERTMS and create a situation that causes a train to halt. Thu...

Radix Notoginseng (commonly known as notoginseng or sanqi) is an herb primarily indicated for bloodand circulation-related conditions. In traditional Chinese medicine, notoginseng is often used together with other herbs to halt both internal and external bleeding, although the effects are mostly attributed to notoginseng itself [1]. Experimental findings have provided support to other effects, ...

As a consequence of the rapid growth of temporary agency employment in Germany the debate on the remuneration of temporary agency workers has intensified recently. The study finds that the temp wage gap in Germany is indeed large. Decomposition reveals that the gap is mainly driven by differences in personal characteristics. Temps already suffer from a marked wage decline before entering the te...

According to the aging phenomenon that di-methyl silicon oil working as a cooling material for liquid-immersed concentrating photovoltaic system for long time. In this paper, the method that enhances the weather-resistance of silicon oil by adding additives was proposed. Hydroxy-4-methoxy-benzophenone (UV-9) and a hindered amine light stabilizer named GW-783 were selected as additive to prepare...

Electric field-induced locomotion and transport of worms Caenorhabditis elegans (C. elegans) in a microfluidic device (electrotaxis) is demonstrated in this paper. Direct (DC) and alternating (AC) electric fields inside a microchannel were used to stimulate worms locomotion towards the negative pole and to halt their locomotion while localizing them at desired locations in the channel respectiv...

Filtering large amounts of unsolicited bulk e-mail, also known as spam, is expensive. Either because of the time spent on manual deletion or complex analysis by algorithms putting heavy load on e-mail servers. Due to exponential growth of the volume of spam campaigns, Internet Service Providers (ISP’s) are increasingly forced to use rigorous rejection policies to prevent their filter servers fr...

In this paper, we study the dynamics of absolute return, trading volume and bid–ask spread after the trading halts using high-frequency data from the Shanghai Stock Exchange. We dealwith all three types of trading halts, namely intraday halts, one-day halts and inter-day halts, of 203 stocks in Shanghai Stock Exchange fromAugust 2009 to 2011.We find that absolute return, trading volume, and in ...

This report presents a method for investigation of speech planning processes that uses a stop-signal paradigm. An experiment was conducted to investigate how produced speech rhythm and syllable stress influence the ability to halt speech in mid-utterance. Subjects produced three sentences with precisely controlled metrical patterns, and on 75% of trials were given a signal at a random time to s...
