Assessment of surface water quality: Case study of Oued Fez catchment areas (Morocco)

Environmental and Sustainability Indicators
Under sustainable development conditions, water quality and quantity play a crucial role in meeting basic human needs. To meet the growing demand for water, surface water quality management is an important aspect.

Effect of storage on bacteriological quality of borehole water

African Journal of Clinical and Experimental Microbiology, 2005
The effect of storage on the bacteriological quality of water from a borehole was investigated. Water samples drawn from the borehole were stored in covered tap-fitted buckets of different colours at room temperature. Physicochemical parameters (pH and suspended solids contents) as well as bacteriological parameters (total bacterial and total coliform ...

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Assessment of Bacteriological Quality of Drinking Water in some Household Water Filter Systems in Benghazi City

Journal of High Institute of Public Health, 2008
Water is very important to human beings. Although human life can exist for many days without food, the absence of water for only a few days has fatal consequences.

A chemo‐enzymatic colorimetric cascade for detecting ethylene glycol contamination

The FEBS Journal, EarlyView.
A chemo‐enzymatic cascade is developed for ethylene glycol (EG) detection. EG is oxidized by GoADH with C1‐mediated cofactor recycling to produce glycolaldehyde (GAL). GAL subsequently reacts with purpald to generate a detectable purple chromophore.

Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

The FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.

Evaluation of Water Quality Index in Cabaña River, Moa-Cuba

Minería y Geología, 2021
Quality of surface waters is generally affected by discharges of domestic and industrial waste that alter their physical, chemical and bacteriological properties, rendering them unfit for consumption.

Determination of Bathing Water Quality Using Thermal Images Landsat 8 on the West Coast of Tangier: Preliminary Results

Remote Sensing, 2019
Bathing water quality has been monitored in the west coast of Tangier, Morocco due to increased urban and industrial discharge through the Boukhalef river, using in-situ bacteriological measurements which demand high economical and temporal costs.

Constrictions and shear stress are key determinants of amyloidogenic light chain (AL) amyloidosis

The FEBS Journal, EarlyView.
In this study, we investigate how flow constrictions and shear stress trigger cardiac antibody light chain (AL) fibril formation and deposition. We mimic the mechanical forces exerted by the heart and the microvasculature network using a mini‐peristaltic pump setup and a grid‐type microchannel network, respectively.
