Prediction of the fate of pesticides in soil is of interest from an environmental (pollution) as well as an agricultural (efficacy, carryover) viewpoint. Two environmental parameters that control microbial degradation of pesticides in soil are moisture and temperature. This study was designed to quantify the impact of soil water content and temperature on microbial degradation rates of the inse...

This paper presents a numerical study on the response of the unsaturated zone (UZ) system of Yucca Mountain to heat generated from decaying radioactive wastes emplaced at the proposed repository. The modeling study is based on the current thermal-hydrological (TH) mountain-scale model, which uses a locally refined 2D north-south cross-section and dual-permeability numerical approach. The model ...

A simple model of two vertical modes is constructed and analyzed to reveal the basic instability mechanisms of convectively coupled waves. The main novelty of this model is a convective parameterization based on the quasi-equilibrium concept and simplified for a model of two vertical modes. It hypothesizes 1) the approximate invariance of the difference between saturation moist static energy in...

Microwave remote sensing techniques are used, among others, for temporally and spatially highly-resolved observations of land-surface properties, e.g., for the management of agricultural productivity and water resource, as well as to improve the performances of numerical weather prediction and climate simulations with soil moisture data. In this context, the effective dielectric constant of the...

The majority of mechanical wood properties are negatively affected by moisture within the hygroscopic range, disregarding stress relaxation at very low contents (MC). In contrast, structural integrity and thus brittleness appears to be positively moisture. This study aimed examining effect MC on between oven-dry state well above cell wall saturation (CWS), i.e., approx. 100 %. For both softwood...

Moisture removal and water recovery from the air are vital for regulating indoor humidity mitigating scarcity. Most atmospheric harvesters (AWH) focus primarily on increasing moisture capture rate, but it to be economical sustainable, is essential consider energy required recover harvest captured water. Here, a mechanically flexible, biphilic sorption-based AWH made of green, environmentally fr...

Using time domain NMR, the moisture in Norway spruce (Picea abies (L.) Karst.) sapwood subjected to four different treatments (never-dried, dried and remoistened, acetylated, and furfurylated) was studied during drying at 40°C, at sample average moisture contents above fiber saturation. Spin-spin relaxation time distributions were derived from CPMG relaxation curves using multiexponential fitti...

The process by which human fingers gives rise to stable contacts with smooth, hard objects is surprisingly slow. Using high-resolution imaging, we found that, when pressed against glass, the actual contact made by finger pad ridges evolved over time following a first-order kinetics relationship. This evolution was the result of a two-stage coalescence process of microscopic junctions made betwe...

OBJECTIVE To assess the physiological impact of the N95 filtering facepiece respirator (FFR) on healthcare workers. METHODS Ten healthcare workers each conducted multiple 1-hour treadmill walking sessions, at 1.7 miles/h, and at 2.5 miles/h, while wearing FFR with exhalation valve, FFR without exhalation valve, and without FFR (control session). We monitored heart rate, respiratory rate, tida...

The impact of the Degree Saturation (DOS) on granular Sub Base material was investigated in this study. Seven numbers CBR (California Bearing Ratio) samples were fabricated at 95% compaction according to Standard Australian, AS 1289.6.1.1. These prepared against targeted moisture variation between DOS 50% and 70%. In particular, laboratory through proper gradation with optimum content (OMC) app...
