In this study, the fibers produced from the banana plants provided from Antalya region were treated with a variety of mordants, and then the fibers were dyed with the natural dye extracted from turmeric plant (Curcuma longa) via ultrasonic and conventional method. Finally, the dye uptake and fastness properties of samples were investigated. The recent studies have demonstrated that the synthetic dyes can be non-biodegradable, allergenic, cytotoxic and partially carcinogenic. Recently demand for eco-friendly, non-carcinogenic and non-toxic products have been gradually increased. Compared to the synthetic dyes, the natural dyes are advantageous in the way of been biodegradable and non-toxic and not causing health problems, produced under temperate conditions. These properties of natural dyes lately result in increasing their usage. Today utilization of many plant extracts as natural dyes has been investigated such as turmeric plant.

In this study, flax fabrics were applied with oxygen and nitrogen plasma treatment for different execution time. After the plasma treatment, the effects of gas type and execution time on flax fabrics were investigated in terms of shear strength, hydrophility, color differences, dimensional change and surface properties. According to the results, nitrogen plasma treatment caused to increase the shear strength of flax fabrics more than oxygen plasma treatment. Furthermore, the oxygen and nitrogen plasma treatment caused to increase of hydrophility of flax fabrics and the hydrophility of samples increased with the increment in execution time of plasma treatment. The color differences results indicated that there were not significant differences in color change of flax samples. Besides, scanning electron microscope images demonstrated that the nitrogen plasma treatment provided the optimal surface modification. According to the results, plasma treatment can be improved the physical and chemical properties of flax fabrics.

After COVID-19 was first observed in Wuhan at the end of 2019, it spread all over the world and became a pandemic which has yet to end. The United States Food and Drug Administration (FDA) suggested that convalescent plasma obtained from individuals who’ve recovered from COVID-19 might be helpful in treating COVID-19 infections, and this treatment has started to be applied in various countries. Convalescent plasma started to be used in Turkey to treat COVID-19 as per a decision of the Ministry of Health. The Turkish Red Crescent has been placed in charge of the convalescent plasma supply. In this scope, objectives for recruiting convalescent plasma donors have been set in motion. The supply of convalescent plasma required for COVID -19 treatment has been conducted in three main stages: managing the course of operations, determining donor selection criteria, and recruiting donors. For the course of operations, convalescent plasma donation centers have been founded, and a national reference guide has been prepared about convalescent plasma donations in addition to documents for providing standard practices in line with this guide. Convalescent plasma donor selection criteria have been defined, followed by convalescent plasma donor recruitment strategies. This study summarizes the Turkish Red Crescent’s experiences and the strategies used to encourage individuals to donate convalescent plasma.
