A pre-phylogenetic revision of the family Phalacridae at the genus level is presented. Twenty-eight new generic synonymies are established as follows: Acylomus Sharp 1888 (=Liophalacrus Sharp 1888, syn. nov.; Ganyrus Guillebeau 1894, syn. nov.; Podocesus Guillebeau 1894, syn. nov.; Tinodemus Guillebeau 1894, syn. nov.; Ledorus Guillebeau 1895, syn. nov.; Astenulus Guillebeau 1896, syn. nov.; Af...

The present study investigated changes in suspension stability and ecotoxicity of engineered nanoparticles (ENPs) by addition of Suwannee River natural organic matter and aging of stock and test suspensions prior to testing. Acute toxicity tests of silver (Ag), zinc oxide (ZnO), and titanium dioxide (TiO2 ) ENPs with Daphnia magna were carried out following Organisation for Economic Co-operatio...

BACKGROUNDS/AIMS The aim of this study was to compare operative versus non-operative management of patients with liver injury and to ascertain the differences of the clinical features. METHODS From April 2000 to July 2012, 191 patients were admitted to Seoul St. Mary's Hospital and St. Vincent's Hospital for liver injuries. Of these, 148 patients were included in this study. All patients were...

A long-standing problem in aquatic geochemistry has been the incorporation of natural organic matter (NOM) into speciation models. The general effect of NOM on metal ion sorption by particles has been understood for some time, and significant progress has been made in elucidating some of the details of the role of NOM through the use of surrogate organic acids such as citric acid. However, a ga...

47 Blunt abdominal trauma is a major cause of abdominal injury in children. The liver is the second most commonly injured organ followed by the spleen1. Nonoperative management (NOM) became the main choice for hemodynamically stable patients with solid organ injury (SOI)2-4. The reported success rate of NOM in pediatrics reached up to 90%3. Adjunct arterial embolization, if indicated, increases...

The extraction and determination of aliphatic and aromatic carboxylic acids as well as their influence on the aromaticity and molecularity relationship of natural organic matter (NOM) in water are reported in this study. Three solid phase extraction (SPE) sorbents were used and their extraction efficiencies evaluated after chromatographic determinations (using gas chromatography with a time of ...

Effect of natural organic matter (NOM) on the stability of inorganic arsenic species in simulated raw water was examined at circumneutral pH. An ion chromatography-inductively coupled plasma mass spectrometry system was used for simultaneous determination of As(1I1) and As(V). A reduction of arsenate (As(V)) to arsenite (As(lll)) was observed in the unfiltered simulated raw waters (USW). The As...

BACKGROUND The daily television program 'the Netherlands on the Move' (NOM-tv), which primarily targets people aged over 55 (estimated Dutch 55+ population: 4 million), was designed as part of a national campaign for promoting physical activity. The aim of the study was to identify the determinants of exercise participation and viewing NOM-tv. METHODS The method used was baseline test by quot...

OBJECTIVES The aim of this study was to introduce the concept of non-operative management (NOM) for blunt liver trauma by establishing a protocol and a prospective Liver Trauma Registry in Kuwait. SUBJECTS AND METHODS A prospective Liver Trauma Registry was started in 4 hospitals and it included 117 patients who had sustained blunt liver trauma (94 men and 23 women). Unstable patients were ta...

Natural organic matter (NOM) is ubiquitous and is one of the most complex naturally occurring mixtures. NOM plays an essential role in the global carbon cycle; atmospheric and natural water photochemistry; and the long-range transport of trace compounds and contaminants. There is a dearth of separation techniques capable of resolving this highly complex mixture. To our knowledge, this is the fi...
