A nematode that can manipulate the behaviour of slugs.

The ability of parasites to manipulate the behaviour of their hosts has evolved multiple times, and has a clear fitness benefit to the parasite in terms of facilitating growth, reproduction and transfer to suitable hosts. The mechanisms by which these behavioural changes are induced are poorly understood, but in many cases parasite manipulation of serotonergic signalling in the host brain is implicated. Here we report that Phasmarhabditis hermaphrodita, a parasite of terrestrial gastropod molluscs, can alte...


Quality Control: Water Activity Considerations for Beyond-use Dates.

There are minimum levels of water activity that are required for growth of bacteria and molds. Water activity is the ratio of vapor pressure of water in a product to pure water at the same temperature. Pure distilled water has a water activity of 1. Water activity is also a measure of water in a material that is available to react with or attach itself to other material; it is also called "free" water while the unavailable water is called "bound" water. Higher water activity substances tend to support more ...

Water use for shale gas extraction in the Sichuan Basin, China.

This study investigates the use of water for extracting shale gas in the Sichuan Basin of China. Both net water use and water intensity (i.e., water use per unit of gas produced) of shale wells are estimated by applying a process-based life cycle inventory (LCI) model. The results show that the net water use and water intensity are around 24500 m/well and 1.9 m water/10 m gas respectively, and that the fracturing and completion stage of shale gas extraction accounts for the largest share in net water ...


Reusable endoscopic water bottles - is daily renewal really necessary?

Most guidelines recommend replacing endoscopic water bottles at least daily with newly sterilized or high-level disinfected water bottles. All these recommendations, however, are mainly based on expert opinions and outbreak reports. We tested the water quality from water bottles used in a gastrointestinal endoscopy unit where water bottles were used up to five days. The results show that the reuse of water bottles for more than one day is inadequate. The expert opinion of changing water bottles daily rather...

Evaluation of ozonated water on the basis of ASTM E1174 for standardized testing of hand wash formulations for healthcare personnel.

We evaluated the bacterial removal effects of hand washing with ozonated water using the ASTM E1174 standard test method. Thirty healthy volunteers were assigned randomly to three groups: ozonated water, antimicrobial soap and water, and non-antimicrobial soap and water. A 3 logCFU reduction was achieved by washing hands with ozonated water or antimicrobial soap and water. However, ozonated water was not significantly superior to non-antimicrobial soap and water. Ozonated water may remove bacteria from the ...

The effects of different types of submerged macrophytes on the phosphorus fraction in the overlying water and interstitial water were explored. The results indicated a significant influence on the concentration of dissolved phosphorus in the overlying water and interstitial water...

Harvesting Water from Air: Using Anhydrous Salt with Sunlight.

Atmospheric water is abundant alternative water resource, equivalent to 6 times of water in all rivers on Earth. This work screens 14 common anhydrous and hydrated salt couples in terms of their physical and chemical stability, water vapor harvesting and release capacity under relevant application scenarios. Among the salts screened, copper chloride (CuCl2), copper sulfate (CuSO4) and magnesium sulfate (MgSO4) distinguish themselves and are further made into bi-layer water collection devices, with the top l...

Synthesizing water quality indicators from standardized geospatial information to remedy water security challenges: A review.

Water is vital not only for food, energy and sanitation but also for ecosystem functioning, human health, socio-economic progress and poverty reduction. Water security exists when all people have physical and economical access to sufficient, safe, and clean water that meets basic needs. However, water security is threatened by growing human population, episodic environmental disasters, indiscriminate land management practices, contaminants, and escalation in geopolitical conflicts.

From aquaporin to ecosystem: Plants in the water cycle.

Vascular plants are major intermediaries in the global water cycle, and are highly adapted to both facilitate and resist water fluxes, such as during root uptake, translocation in the xylem, and transpiration by leaves. Here, we summarize the contributions to a Special Issue on water in the Journal of Plant Physiology, which cluster around the theme of control and facilitation of water movement in plants. We conclude with an editorial view of the need for plant physiologists to consider larger cultural issu...

Drivers of microbiological quality of household drinking water - a case study in rural Ethiopia.

This study aims at assessing the determinants of microbiological contamination of household drinking water under multiple-use water systems in rural areas of Ethiopia. For this analysis, a random sample of 454 households was surveyed between February and March 2014, and water samples from community sources and household storage containers were collected and tested for fecal contamination. The number of Escherichia coli (E. coli) colony-forming units per 100 mL water was used as an indicator of fecal contami...

Driven water/ion transport through narrow nanopores: a molecular dynamics perspective.

Atomistic Molecular Dynamics (MD) simulations provide numerous insights into the process whereby water is driven through a narrow nanopore (diameter on the order of a few water molecules) by application of hydrostatic pressure. If there are ions in the water, e.g., from dissolved salt, these may be swept along with the flowing water. If the surface of the nanopore is charged, electrostatic interaction between the surface charges and the ions as well as with partial charges on the water molecules will influe...

STABLE OXYGEN ISOTOPES IN WATER OF CONCENTATED LIQUID FOODSTUFFS: ARE THE COMMONLY DETERMINED VALUES ACCURATE?

Oxygen isotope analysis of water molecules of liquid foodstuffs is commonly performed under isotopic equilibrium between water in the solution and the vapour water, assuming that the liquid water activity is equal to unity and that liquid water is an ideal mixture of H O isotopologues. A priori this behaviour is not realistic for all foodstuffs, which frequently are very concentrated solutions. In this paper we mainly consider "balsamic vinegar" with the aim of defining an appropriate procedure of oxygen is...

Is the default of 2 liters for daily per-capita water consumption appropriate? A nationwide survey reveals water intake in Japan.

Two liters per day is generally applied as the default drinking water intake rate for risk assessments, although evidence supporting this value is insufficient. This study aimed to reveal actual water intakes from tap water and other types of drinks, and to explore the relationships between these intakes. For this purpose, we conducted a nationwide Internet questionnaire survey. Tap water intake negatively correlated with bottled water and soft drink intakes, suggesting a mutually complementary relationship...

Distribution of tightly and loosely bound water in biological macromolecules and age-related diseases.

This mini-review article is focused on publications devoted to the changes in water binding energy and content of bound water in biological tissues during aging processes, when bound water lost from the hydration layer becomes free water. Bound water is released during cataractogenesis. In skin, water bound to proteins and other biomacromolecules becomes more mobile with increasing skin age. Extracellular to intracellular water ratio increases with age and was associated with muscle cell atrophy. Bound wate...

Access to drinking water: time matters.

Despite the reported achievement of the Millennium Development Goals (MDGs) with respect to drinking water, lack of access to water remains widespread worldwide. The indicator used there to measure access to water in the MDGs refers to the use of an improved water source. However, the amount of time spent in collecting water is high in countries where access to drinking water supplies located on premises is not common. 26.3% of the world's population did not have such access in 2015. Thus the need to travel...

Equipment factors affecting identification of water level with echo for the blind.

Blind people adopt their remaining intact senses to perceive the world for tasks such as determining the water level in a bowl. Pouring water into a bowl generates water sounds and echoes reflected in the bowl. This research develops a bowl with increased echo (called an echo bowl), and analyzes the accuracy of water levels perceived by visually impaired people using a container or a kettle to pour water into a common bowl or an echo bowl. The analysis of factors of pouring and filled equipment indicates th...

The potential of the tree water potential.

Non-invasive quantification of tree water potential is one of the grand challenges for assessing the fate of trees and forests in the coming decades. Tree water potential is a robust and direct indicator of tree water status and is preferably used to track how trees, forests and vegetation in general respond to changes in climate and drought. In this issue of Tree Physiology, Dietrich et al. (2018) predict the daily canopy water potential of mature temperate trees from tree water deficit derived from stem d...

Structure and Dynamics of Water Confined in Imogolite Nanotubes.

We have studied the properties of water adsorbed inside nanotubes of hydrophilic imogolite, an aluminium silicate clay mineral, by means of molecular simulations. We used a classical force field to describe the water and the flexible imogolite nanotube, and validated it against data obtained from first-principles molecular dynamics. With it, we observe a strong structuration of the water confined in the nanotube, with specific adsorption sites and a distribution of hydrogen bond patterns. The combination of...

Spin-Isomer Conversion of Water at Room Temperature and Quantum-Rotor-Induced Nuclear Polarization in the Water-Endofullerene H_{2}O@C_{60}.

Water exists in two forms, para and ortho, that have nuclear spin states with different symmetries. Here we report the conversion of fullerene-encapsulated para water to ortho water. The enrichment of para water at low temperatures is monitored via changes in the electrical polarizability of the material. Upon rapid dissolution of the material in toluene the excess para water converts to ortho water. In H_{2}^{16}O@C_{60} the conversion leads to a slow increase in the NMR signal. In H_{2}^{17}O@C_{60} the c...

Recycling of drinking water treatment residue as an additional medium in columns for effective P removal from eutrophic surface water.

This study assesses the feasibility of recycling drinking water treatment residue (DWTR) to treat eutrophic surface water in a one-year continuous flow column test. Heat-treated DWTR was used as an additional medium (2%-4%) in columns in case excessive organic matter and N were released from the DWTR to surface water. The results indicated that with minimal undesirable effects on other water properties, DWTR addition substantially enhanced P removal, rendering P concentrations in treated water oligotrophic ...

Effect of humidity and water intercalation on the tribological behavior of graphene and graphene oxide.

In this work, the effect of humidity and water intercalation on the friction and wear behavior of few-layers of graphene and graphene oxide (GO) was studied using friction force microscopy. Thickness measurements demonstrated significant water intercalation within GO affecting its surface topography (roughness and protrusions), whereas negligible water intercalation of graphene was observed. It was found that water intercalation in GO contributed to wearing of layers at a relative humidity as low as ~30%. T...

Long-term evaluation of water quality parameters of the Karoun River using a regression approach and the adaptive neuro-fuzzy inference system.

This paper investigates chemical water quality parameters of the Karoun, the greatest and the most important river of Iran, during a 48-year period, from 1968 to 2015. Water discharge (Q) fluctuates between 191.1m3s-1 and 1758.7m3s-1, with a decreasing trend over the 48-year period. Except pH, other water quality parameters increased, significantly, so that the rate of increase for EC and TDS was 25.71μScm-1y-1 and 16.66mgl-1y-1, respectively. Moreover, SO4-2, HCO3-, Cl-, Ca+2, Mg+2 and Na+ have increased ...

Water Exchange Produces Significantly Higher Adenoma Detection Rate Than Water Immersion: Pooled Data From 2 Multisite Randomized Controlled Trials.

To test the hypothesis that water exchange (WE) significantly increases adenoma detection rates (ADR) compared with water immersion (WI).

Application of a hydroxyl-radical-based disinfection system for ballast water.

A hydroxyl radical (OH) ballast water treatment system (BWTS) was developed and applied to inactivate entrained organisms in a 10,000-ton oceanic ship, where OH was produced by a strong ionization discharge combined with a water jet cavitation effect. The calculated OH generation rate was 1373.4 μM min in ballast water, which is much higher than that in other advanced oxidative processes such as photocatalysis. As a result, non-indigenous red tide algae were inactivated to meet the ballast water discha...
