Traditional Turkish Coffee with Medicinal Effect

Traditional Turkish coffee (TTC) is highly associated with caffeine and is known as a mind and heart stimulant as it helps keep tiredness at bay. Daily consumption of TTC naturally benefits human health such as anti-cancer, anti-diabetic, improved energy, anti-depression, reduced risk of heart disease, etc. The TTC was derived from particular types of Arabic coffee beans (ACB), and the preparation method of TTC is unique from other types of coffee. The main objective of the study was to investigate the therapeutic and biological effects of TTC. The ACB powder was characterized physicochemically using UV-Vis spectroscopy, Fourier transforms infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). In vitro analysis using HaCaT (Human keratinocyte cell line) proved the biocompatibility of ACB powder. Case studies which were focusing on healthy individuals as the research populace were conducted using TTC. Consumption of TTC was found beneficially compared to other types of coffee. The TTC was obtained from ACB, which was characterized by spectroscopic techniques and displayed biocompatibility due to the results on HaCaT cell lines. The TTC has beneficial therapeutic effects on individuals. According to statistical analysis, the disease-affected ratio of diabetes, heart disease, and depression was significantly decreased

SARACİYELİK DERİLERDE YAĞLAYICI AKRİLİK POLİMERİN YAŞLANMA ÜZERİNE ETKİSİ

Vegetable tannins are used in the production of shoe upper, saddlery as well as heavy, firm and resistant leathers. They are viable ecological replacements of chromium and other inorganic tanning agents which show high hydrophilic character and sensitivity to rubbing and sunlight. To improve these properties, vegetable tanned leathers are treated with polymeric materials. In the study, accelerated ageing was applied to saddlery leathers treated with different amounts of lubricating acrylic polymer. The effect of ageing was determined in accordance with tensile and tear strength, water vapor permeability, color measurement, rubbing and light fastness in addition to morphological properties. It is found that the negative effect of ageing can be eliminated by 8% application of acrylic polymer.Bitkisel tabaklama maddeleri ayakkabılık ve saraciyelik derilerin üretimi yanında ağır, sert ve dolgun derilerin üretiminde de kullanılmaktadır. Krom ve diğer inorganik tabaklama maddelerinin ekolojik ikamesi olabilen bitkisel tabaklama maddeleri; hidrofil karakterdedirler, sürtmeye ve güneş ışınlarına karşı hassasiyet gösterirler. Bu özelliklerini geliştirmek için bitkisel tabaklanmış deriler, polimerik malzemelerle muamele edilirler. Çalışmada, farklı oranlarda yağlayıcı akrilik polimerlerin kullanıldığı saraciyelik derilere hızlandırılmış yaşlandırma işlemi uygulanmıştır. Yaşlandırmanın etkisi, derilerin çekme ve yırtılma mukavemeti, su buharı geçirgenliği, sürtme, renk ve ışık haslığı değerleri ile morfolojik özellikleri açısından değerlendirilmiştir. Sonuç olarak, yaşlanmanın olumsuz etkisinin %8 yağlayıcı akrilik uygulaması ile elimine edilebileceği belirlenmiştir
