Effect of pH, Chlorine Residual and Turbidity on the Microbial Bio Indicators of Drinking Water Network

Medical Laboratory Journal, 2015
Background and objective: Bioindicators of drinking water are always influenced by physical and chemical factors such as turbidity and chlorine.  Considering the assessment of drinking water quality is based on residual chlorine, E.coli, heterotrophic ...

Investigating the physical and chemical factors affecting the microbial status of water in the water distribution network of Babol City with an emphasis on the HPC index.

PLoS ONE
Background and purposeSafe and hygienic drinking water is crucial for public health. Secondary bacterial contamination, often caused by improper transport and distribution conditions, poses a significant threat.

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

Advanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Residual chlorine management in water distribution systems using network modelling techniques: case study in Seoul City

, 2004
Twelve sampling locations in a network from a water treatment plant to consumers' taps were selected for measuring residual chlorine loss, THMs, TOC, etc. and 24 hour sampling in the locations was conducted on a bimonthly basis for one year.

[Residues of chlorinated hydrocarbons in milk].

Roczniki Panstwowego Zakladu Higieny, 1996
In 1994 samples of bovine milk were taken in 98 sampling points (2 in each of 49 districts of Poland). Levels of organochlorine pesticides and polychlorinated biphenyls (PCB) were determined by capillary gas chromatography. In almost all milk samples DDT and PCB residues were found.

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

Advanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.
