In this paper a mathematical model for the soda ash drying process in pneumatic dryer was presented. The presents macroscopic aspect of process, two-phase, gas-solid system. is based on mass and heat transfer between gas phase particle, movement air particles through system, geometric characteristics system (fan, heater, dryer, cyclone). effects parameters, such as airflow, inlet temperature, r...

The present study was conducted in the northern outskirts of the Jaworzno town situated in the Upper Silesia, the most industrialized part of Poland, where the over hundred-year-old landfill site of soda ash waste is situated. The 10 waste samples and 10 topsoil samples were collected. Value of the pH and the total load of selected heavy metals (Cd, Cr, Pb and Zn) were determined for both types...

Electrochemistry on gases originated in 1839 with Grove's "gaseous voltaic battery". Over 90 years later, Bacon built a demonstration fuel cell consisting of porous nickel electrodes. He is credited with creating a stable three phase reaction zone of electrode, gas, and electrolyte. Today's fuel cell electrodes are far more sophisticated and lend themselves to other important electrochemical pr...

OBJECTIVE This study aimed to compare diet soda drinkers, regular soda drinkers, and individuals who do not regularly consume soda on clinically significant eating disorder psychopathology, including binge eating, overeating, and purging. METHOD Participants (n=2077) were adult community volunteers who completed an online survey that included the Eating Disorder Examination Questionnaire and ...

Abstract International expeditions extensively excavated Lower Nubia (between the First and Second Nile Cataracts) before it was submerged under waters of Lake Nasser Nubia. The concentrated on monumental architecture cemeteries, including sites at Qustul Serra East, where New Kingdom, Napatan, Meroitic, Nobadian, Makurian-period elites common people were buried, ca. 1400 BC–AD 1400. Although f...

The carbonation tower is a key reactor to manufacturing synthetic soda ash using the Solvay process. Because of the complexity of the reaction in the tower, it is difficult to control such a nonlinear large-time-delay system with normal measurement instrumentation. To solve this problem, a time-delay neural network (TDNN) is used in the soft measurement model in this paper. A special back-propa...

A chromium-loaded ash originating from incineration of tannery sludge under anoxic conditions was mixed with low grade soda-lime glass powder coming from commercial glass bottles. The relative weight proportions of ash over glass powder tested were 30/70, 40/60 and 50/50. The solid mixtures, formed in green state compacts, were sintered at the temperature range of 800C up to 1200C. The resultin...

OBJECTIVE Diet soda consumption increases cardiometabolic risk. The aim of this investigation was to assess the relations between self-reported soda consumption and subclinical cardiac remodeling. METHODS We assessed the relations between self-reported soda consumption and left ventricular mass (LVM) and left atrial dimension (LAD) (both standardized within sex) in a sample of middle-aged att...

OBJECTIVE To determine if baking soda toothpastes are relatively more effective than non-baking soda toothpastes in promoting plaque removal from less accessible sites in the dentition. METHODS Several single-brushing comparisons of baking soda and non-baking soda toothpastes for their overall ability to remove plaque have been published. In this study, individual comparisons of these publish...

The present study examines the direct effects of television commercials advertising soda on actual sugar-sweetened soda consumption among young women. An experimental-observational study design was used, in which 51 female students (ages 18-29) were exposed to a 35-min movie clip, interrupted by two commercial breaks consisting of soda or water commercials. Their actual soda consumption while w...
