Factors associated with adherence to safe water chain practices among refugees in Pagirinya refugee settlement, Northern Uganda

Poor adherence to safe water chain practices is a major obstacle to consumption of safe drinking water. In refugee settings, adherence to safe water chain is critical in minimizing water-related diseases. Despite this, little is known about the level of adherence to safe water chain and associated factors, especially in emergency settings. In this study, we interviewed 400 household heads in Pagrinya refugee camp in Northern Uganda and assessed household level adherence to safe water chain practice and associated factors. Modified Poisson regression was used to model the association between adherence to safe water chain and independent variables. All households utilized improved water sources and 74.0% had high adherence to safe water chain. Having post-primary education and high level of knowledge about the safe water chain were positive predictors of high adherence to the safe water chain while round travel time exceeding 1 hour during water collection was negatively associated with high adherence. There is a need for awareness campaigns on safe water chain maintenance among refugees without any formal education. Constructing more water sources would also minimize round travel time during water collection and enable households to collect sufficient water that enables hygienic water storage and use.

Double Palindrome Water Chain in Cu(II) Theophylline Complex. Synthesis, Characterization, Biological Activity of Cu(II), Zn(II) Complexes with Theophylline

Two metal complexes of theophylline were synthesized. Namely, 1 with the formula [Cu(theop)2(H2O)3]·2H2O and 2, [Zn(theop)2]∙H2O (where: theop = theophylline ion). Their properties were thoroughly investigated by the elemental analysis (EA), flame atomic absorption spectrometry (FAAS), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA) that were augmented by antimicrobial and antioxidant analyses. Their radical scavenging ability (RSA) is notably higher than that of a pure theophylline itself. Similarly to theophylline complexes already studied by us 3, [Mn(theop)2(H2O)4] 4, [Co(theop)2(H2O)4] and 5, [Ni(theop)2(H2O)4] title compounds are inactive against Gram-negative bacteria, but they show moderate or mild activity against Gram-positive rods. The low temperature, single crystal X-ray diffraction technique determines the crystal structure of 1. Its supramolecular crystal topology is affected by the unique, double palindrome water chain that formed by two conserved and a sole coordinated water molecules. Crystal packing arrangements were characterized by fingerprint plots that were derived from the Hirshfeld surfaces (HS), as calculated for all structures in the series 1, 3, 4, 5.

From a bulk to nanoconfined water chain: bridge water at the pore of the (6,6) carbon nanotube

Hydrophobic porous materials with nano-pores are critical in many processes such as water desalination and biological membrane transportation.

Enhanced wettability of long narrow carbon nanotubes in a double-walled hetero-structure: unraveling the effects of a boron nitride nanotube as the exterior

The electrostatic heatmap of hetero-nanotube confirms that the implementation of the outer wall led the liquid–solid quasi-phase transition of single-file water chain in the long CNT (5,5).

Mechanistic study of the ATP hydrolysis reaction in dynein motor protein
