This study investigated the fresh, physical, and mechanical properties of self-compacting geopolymer mortars (SCGs) with synthetic wollastonite microfiber (SWM). SCGs were designed Class F fly ash (FA) as a binder by activating it Na2SiO3 NaOH solutions. First, SWM was produced in laboratory. Alkali ratios determined 1.5, 2.0, 2.5, whereas percentages utilized 0%, 4%, 8%, 12% weight binder. Aft...

Solid waste management (SWM) in rural areas of many low- and middle-income countries (LMICs) represents a critical underrated topic. However, almost half the world’s population still lives an adequate SWM is crucial reducing environmental health threats. A lack knowledge appropriate tools often leads to inappropriate practices such as dumping uncontrolled burning. methods can transform into res...

Seasonality in carbon chemistry of Cochin backwaters, Southern India, was investigated between 2018 and 2019. Dissolved inorganic (DIC) showed strong seasonal variations. Lowest DIC observed during the Southwest Monsoon (SWM), conjunction with low salinity surface waters, suggesting freshwater influence. The maximum concentration partial pressure dioxide water (pCO 2 w) recorded from polluted w...

The present study aimed at investigating the association between short-term heart rate variability and executive function performance in two groups of adult population, that is, young adults middle-aged adults. influence physical activity on was also analyzed. A cross-sectional conducted 143 adults; 65 78 Each participant’s recorded during ideal state, task recovery state. tests included Delaye...

A brief review is provided of the use of the Square Wave Method (SWM) in the field of signal and image analysis and it is specified how results thus obtained are expressed using the Square Wave Transform (SWT), in the frequency domain. To illustrate the new approach introduced in this field, the results of two cases are analyzed: a) a sequence of samples (that is, measured values) of an electro...

Over the last decade, great strides have been made in land surface modeling at regional to continental scales. The North American Land Data Assimilation System has developed new approaches for estimating current land surface moisture conditions (e.g., soil moisture, snow and runoff) as well as retrospective reconstructions of the same variables. These science-based products were motivated by a ...
