Experimental and Numerical Study on Enhancing the Performance of a Stepped Solar Still Using Porous Sponge Materials

open access: yesEnergy Science &Engineering, EarlyView.
Three designs were built and tested: a single‐slope still, a six‐stepped still, and a six‐stepped still with 5 mm sponge sheets. The novelty lies in fixing porous sponge sheets to the vertical faces of the steps. Yield of freshwater and instantaneous efficiency were determined in various combinations, that is, base, stepped, and stepped‐cum‐sponge ...

Infant frontal alpha asymmetry predicts social attention and transdiagnostic risk for emotional reactivity

open access: yesJCPP Advances, EarlyView.
Abstract Background Differences in Frontal Alpha Asymmetry (FAA), derived from the electroencephalogram (EEG), have been associated with approach‐withdrawal behavior, although inconsistently. The current study examined how early patterns of FAA during the first 2 years of life relate to various socioemotional characteristics (at 2 years) and ultimately

Slum‐Based CAV Networks: Networking in Unyielding Poverty Situations

open access: yesStrategic Change, EarlyView.
ABSTRACT Over a billion of the world's population reside in slums. However, the configurations of their social and structural ties in these environments remain unsubstantiated. Drawing on a psychosociological rational choice perspective, we introduce theoretical explanations distinguishing slum dwellers' behavior, actions, and attitudes in community ...

Exploring Electrical Resistivity Tomography (ERT) to Detect Soil Pipes: Theoretical Modeling and Field Experiments

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil erosion research remains critical for sustainable development as it impacts soil health through different erosive processes. Recent studies on soil piping highlight advancements in detecting surface features (using UAV); however, detecting underground pipes still remains challenging.
