A laser-induced graphene (LIG) modified with chitosan (Chit) and conducting polymer polyfolate (PFA) was used as a base to develop flat flexible pH sensor. LIGs were formed using two different irradiation wavelengths of 355 nm 532 nm. Depending on the wavelengths, obtained electrodes named LIG355 LIG532. Microscopic imaging revealed that bare LIG electrode surface had rough structures after las...

Patient flow analysis (PFA), a simple quality improvement tool to identify patient flow patterns, can be used in resource-limited settings to inform service delivery improvements. A PFA at a Ghanaian hospital found that personnel constraints and a mismatch between staffing and patient arrival surges led to long wait and total attendance times. The median time from arrival to first-provider cont...

The Proper Forcing Axiom implies that compact Hausdorff spaces are either first-countable or contain a converging $$\omega_1$$ -sequence.

The Pfaaan of a graph is closely linked to Perfect Matching. It is also naturally related to the determinant of an appropriately deened matrix. This relation between Pfaaan and determinant is usually exploited to give a fast algorithm for computing Pfaaans. We present the rst completely combinatorial algorithm for computing the Pfaaan in polynomial time. In fact, we show that it can be computed...

We survey some recent results on the impact of strong forcing axioms such as the Proper Forcing Axiom PFA and Martin’s Maximum MM on cardinal arithmetic. We concentrate on three combinatorial principles which follow from strong forcing axioms: stationary set reflection, Moore’s Mapping Reflection Principle MRP and the P-ideal dichotomy introduced by Abraham and Todorčević which play the key rol...

eight genotypes of spring safflower (carthamus tinctorius l.) were evaluated for several physiological traits under stress and non-stress water regimes. data were analyzed using principal factor analysis. the factor analysis technique extracted six factors under non-stress conditions. six factors explained about 80% of the total variation, and only 40% of the variance was accounted for by the f...

Developing product families has been recognized as an effective means to support Mass Customization Manufacturing (MCM). A Product Family Architecture (PFA) resembles the underpinning logiC'of assisting customers to converge to what a firm can deliver in terms of its capabilities and capacities. The representation of a PFA is essential for managing variety effectively across the entire product ...

ADP; however, with the corrected cutoff values, the Innovance PFA P2Y predicted the primary end point (where it did not with the incorrectly calculated cutoff in the original article). In addition, we observed an error in Figure 2 concerning the PFA-100 system. The closure times of the PFA COL/ADP are correct, but for the Innovance P2Y the lower line indicates patients with an end point and sho...
