The aim of this research is to investigate related effect dyeability linen textiles different printing parameters. study investigated the change in color characteristics when on fabrics with an inkjet MIMAKI Tx400-1800D printer pigmented TP 250 inks. dependence reproduction number print head passes, ink layers be coated, fabric density, and types was investigated. All affects quality its mechan...

The incidence of enteric bacteria and Staphylococcus aureus in four day care centers in Akwa Ibom State was studied using culture techniques. The percentage frequencies of the isolates from 124 samples were Staphylococcus aureus (33.9), Escherichia coli (19.0), Klebsiella sp (14.4), Citrobacter sp (12.5) and Proteus mirabilis (7.4). The sources of contamination were floors, chairs, skin, bed li...

The discovery of past spikes in atmospheric radiocarbon activity, caused by major solar energetic particle events, has opened up new possibilities for high-precision chronometry. The two spikes, or Miyake Events, have now been widely identified in tree-rings that grew in the years 775 and 994 CE. Furthermore, all other plant material that grew in these years would also have incorporated the ano...

Fabrics are pliable, breathable, lightweight, ambient stable, and have unmatched haptic perception. Here, a vapor deposition method is used to transform off-the-shelf plain-woven fabrics, such as linen, silk, and bast fiber fabrics, into metal-free conducting electrodes. These fabric electrodes are resistant to wear, stable after laundering and ironing, and can be bodymounted with little detrim...

Marine textiles form a vital part of our cultural heritage. Some extant sails and surviving sail fragments in museum collections are hundreds of years old. The Victory sail, from the early 19th century, was not only subject to the ravages of the marine environment during its working life but has since suffered further deterioration during storage and display. To determine the optimum protocol f...

A plausible route for the spontaneous synthesis of an activated ribonucleotide that is poised for polymerization has been put forth (Powner et al. (2009) Nature, 459, 239-242). A key step in this route necessitates the regioselective phosphorylation of the secondary alcohol on C(3') of an anhydroarabinonucleoside in the presence of the primary alcohol on C(5'). Here, we propose that this regios...

We study the regularity of the extremal solution of the semilinear biharmonic equation ∆u = λ (1−u)2 , which models a simple Micro-Electromechanical System (MEMS) device on a ball B ⊂ R , under Dirichlet boundary conditions u = ∂νu = 0 on ∂B. We complete here the results of F.H. Lin and Y.S. Yang [14] regarding the identification of a “pull-in voltage” λ∗ > 0 such that a stable classical soluti...
