This study evaluated the antibacterial activity of Biosecur(®) citrus extract surface cleaner against Vibrio vulnificus using plate count method. Two concentrations, 0.5% and 2% of Biosecur(®) surface cleaner were plated on Vibrio vulnificus Agar (VVA) and tested for reduction of Vibrio vulnificus. In order to investigate the lasting residual activity of Biosecur(®), antibacterial activity test...

Cleaning is a major problem associated with pools. Since the manual cleaning is tedious and boring there is an interest in automating the task. This paper presents methods for autonomous localization and navigation for a pool cleaner to enable full coverage of pools. Path following cannot be ensured through use of internal position estimation methods alone; therefore sensing is needed. Sensor b...

TEM and SEM analysis of the tibio-tarsal antennal cleaner in Messor rufitarsis reveals a pore region on the surface of the basitarsus. These pores are originating from a cluster of highly prismatic epidermal cells that fill the anterior hemolymph space of the leg almost completely. Within the cytoplasma of the cells, basal labyrinth, nucleus/rough endoplasmic reticulum, 'secondary lysosomes', a...

BACKGROUND More than 3 billion of the world's population are affected by household air pollution from relying on unprocessed solid fuels for heating and cooking. Household air pollution is harmful to human health, climate, and environment. Sustained uptake and use of cleaner cooking technologies and fuels are proposed as solutions to this problem. In this paper, we present our study protocol ai...

A water soluble, Bronsted acid, 5-sulfosalicylic acid as an efficient organocatalyst was used for the synthesis of physiologically active 2-substituted benzimidazole derivatives from o-phenylenediamine and aromatic aldehydes in ethanol at reflux condition. Cost-effectiveness, use of non-hazardous solvents, metal free and commercially available catalyst, single-step, environmentally fri...

Developing nations face higher stakes in the race towards a cleaner energy future, where it's matter of life, wealth, and basic human needs. Using Tanzania Panel Survey data, this study examined urban households' cooking choices their impact on reducing poverty. Employing advanced statistical models, it found that traditional sources still dominate methods, households relying them are more like...
