Using state-of-the-art electron microscopy techniques, a team led by researchers from Caltech has for the first time visualized and described the precise arrangement of chemoreceptors -- the receptors that sense and respond to chemical stimuli -- in bacteria. In addition, they have found that ...
The lung flora changes over time in the CF lung. It is also known that the composition of the bacterial community in the lung at any one time varies due to the compartmentalised structure of the organ [34]. When working with expectorated sputum, it was assumed that the bacterial community...
is conducive to the creation of extensive regions exhibiting the desired complex structure. Despite this, the governing of such hierarchical growth is in its initial phase, particularly when considering lanthanide-structured systems. Here, we describe the hierarchical growth process of a Dy-based supram...

Applied to the soil, anhydrous ammonia goes through a series of conversions. It is first in gaseous form and reacts with soil moisture to become ammonium ions (NH4+). These ions easily combine with soil particles and do not escape via leaching. In time, the bacteria in the soil turn ammo...

The key feature of this product is that it has a dual-use structure. The product can be used as a grinder by installing around the meat plate and a cross knife at the outlet and can be used as a sausage stuffer when the enema nozzle is installed. It is also thoroughly washable, compl...
The block character of the Palaeozoic basement structure and the tectonic activity of the main transcontinental dislocations have substantially influenced the development and thickness of Mesozoic deposits on the Carpathian Foredeep basement (e.g. Karpenchuk et al. 2006; Buła and Habryn 2011; Kra...
