−The inhibition of methane production in the continuous anaerobic degradation process for the treatment of sewage sludge containing sulfate was investigated. Also, the competition between sulfate-reducing bacteria (SRB) and methane-producing bacteria (MPB) with COD/sulfate ratio was explained in terms of electron flow. The methane production rate was 0.07, 0.13, 0.24, 0.31 and 0.33 l-CH4 g-COD ...

Aluminum alloy 7075 is an important engineering material for ship structures. However, the corrosion of Al alloys generally exists in various environments, especially marine environment. Currently, behaviors sulfate-reducing bacteria (SRB) environment has not been well-addressed. In this paper, effect SRB on aluminum was studied by adding to real seawater. The microstructure and grain orientati...

Offenders with antisocial traits are relatively likely to attempt suicide, largely because they are more likely to have high negative emotionality and low constraint. Among 682 male offenders, we tested whether negative emotionality, low constraint, and also substance use problems mediated any relationship between antisocial personality disorder (ASPD) and psychopathy on the one hand, and suici...

Data intensive applications constitute a large and increasing share of Grid computing. However there are relatively few results on how to improve the efficiency of the basic data transfer mechanisms used to move large data set in and out of clusters. In this paper we describe a simple and general technique to improve the throughput of data transfer protocols and we demonstrate it on the SDSC St...

An essential building block for any Data Grid infrastructure is the storage server. In this paper we describe a high-performance cluster storage server built around the SDSC Storage Resource Broker (SRB) and commodity workstations. A number of performance critical design issues and our solutions to them are described. We incorporate pipeline optimizations into SRB to enable the full overlapping...

The main objective of this study was to investigate whether the sex ratio at birth (SRB, male proportion) alter in Iraq during its war against Iran (1980-1988). Here we compared 785 births (348 males, 437 females) during 1980-1989 with 1144 births (655 males, 489 females) before 1980 and 2914 births (1496 males, 1418 females) after 1989 in Fallujah, Iraq. The SRB significantly decreased during ...

The relationship between oxygen and microbiologically influenced corrosion (MIC) resulting from obligate anaerobic microbial processes is complex. Most reported cases of MIC of carbon steel and copper alloys in marine environments are caused by sulphate-reducing bacteria (SRB) with some dissolved oxygen in the bulk medium. Yet most laboratory experiments with SRB are conducted in the absolute a...

Surveys that directly ask participants whether they have been abused are likely to derive different results than studies that ask about specific childhood sexual experiences (CSEs) or about experiences with specific types of parental physical aggression, which participants may or may not personally define as abusive. We compared results from the SHIP survey with the results of the confidential ...
