Water is the second important ingredient in coffee preparation after coffee type and affects the coffee quality. In this study, it was aimed to investigate the effects of four different water hardness (bottled, purified, medium hard and hard water) used i... see more

BACKGROUND: Cardiovascular disease (CVD) is one of the common diseases and today, it is considered as not only an important cause of mortality but also a significant aspect of health geography. The evidence presented in the literature indicates that hard ... see more

Water with good quality is water which requires good conditions of physic, chemical, bacteriology, and radioactive. One of chemical requirement is total hardness (CaCO3) with maximum degree 500 mg/L. Water with high level hardness can cause several proble... see more

Calcium hardness of water samples has been determined using a method based upon the energy Dispersive X-ray fluorescence (EDXRF) technique for elemental analysis. the minimum detection limit for Ca has been found in the range 0.1-100ppm. the experimental ... see more

This paper reports the results of studying epoxy compositions with gypsum taken in the form of dispersed powders in the original and water-hardened form. The exact pattern has been shown in the way the introduction of a gypsum additive in the amount of 50... see more

The objective of this work is to determine the physical-chemical variations in the water quality of Carrizal River (Manabí), in 21 sampling stations, covering an area of ??51 km. Seven points were sampled in (i) the microbasin, 5 points in (ii) La Esperan... see more

Maintenance of dissolved oxygen at saturated level will help the growth and reproduction of normal population of fish and other aquatic organisms1,2. Due to increase of industries, it is necessary to monitor the DO level of water resources. This will help... see more

The potability of water is judged by its physical, chemical and biological analysis. While analysing the water quality of Chandrapur district for winter 2012, summer 2013 and post-monsoon 2013 an eccentric observation was observed for total hardness estim... see more

This paper presents the experimental research results, regarding the effect of hydromechanical parameters and based on the relative reduction of the starting hardness of geothermal water of Sijarinska Banja and Niška Banja as well as the water from the Me... see more
