The PM10 airborne particulate matter with an aerodynamic diameter ≤10 µm is considered as a risk factor of various adverse health outcomes, including lung cancer. Here we described the sampling and composition of PM10 collected from an industrial zone (IZ), and a commercial zone (CZ) of Mexico City. The PM10 was collected with a high-volume sampler in the above mentioned locations and both type...

Olfactory sensory axons target well-defined intermediate targets in the zebrafish olfactory bulb called protoglomeruli well before they form odorant receptor-specific glomeruli. A subset of olfactory sensory neurons are labeled by expression of the or111-7:IRES: GAL4 transgene whose axons terminate in the central zone (CZ) protoglomerulus. Previous work has shown that some of these axons mispro...

Growth of the aerial part of the plant is dependent upon the maintenance of the shoot apical meristem (SAM). A balance between the self-renewing stem cells in the central zone (CZ) and organogenesis in the peripheral zone (PZ) is essential for the integrity, function, and maintenance of the SAM. Understanding how the SAM maintains a balance between stem cell perpetuation and organogenesis is a ...

Metal mines mined using the sublevel caving method often exhibit various environmental problems on ground surface. This can affect safety of production process in mining area. A numerical model Universal Distinct Element Code has been established to investigate deformation failure giving rise this underground mining. The calculations are combined with in-situ monitoring data collected over a pe...

Top-coal caving technology is a productive and efficient method in modern mechanized coal mining, the study of coal-rock recognition is key to realizing automation in comprehensive mechanized coal mining. In this paper we propose a new discriminant analysis framework for coal-rock recognition. In the framework, a data acquisition model with vibration and acoustic signals is designed and the cav...

We have irradiated Czochralski silicon (Cz-Si) and Float Zone silicon (Fz-Si) detectors with 24GeV=c and 10MeV protons. Samples were characterized with Capacitance-Voltage measurements (CV), Transient Current Technique (TCT) and secondary electron backscattering recorded by Scanning Electron Microscope (SEM). We present the evolution of the effective doping concentration as a function of irradi...

Giant multilocular prostatic cystadenoma (GMPC) is a rare benign tumor involving the prostate gland. Microscopically, it masquerades phyllodes tumor or transitional zone hyperplasia. We report one case of GMPC arising from the prostate central zone (CZ), presenting with long-standing aspermia associated with seminal vesicle fibrous obliteration.

Observation and quantification of the Earth’s surface is undergoing a revolutionary change due to the increased spatial resolution and extent afforded by light detection and ranging (lidar) technology. As a consequence, lidar-derived information has led to fundamental discoveries within the individual disciplines of geomorphology, hydrology, and ecology. These disciplines form the cornerstones ...

The critical zone (CZ) represents the most-shallow subsurface, where bio-, hydro-, and geospheres interact with anthropogenic activity. To characterize thickness lateral variations of CZ, here we focus on Eastern Betic Shear Zone (EBSZ), one most tectonically active regions in Iberian Peninsula. Within EBSZ, Guadalentín Depression is a highly populated area intensive agricultural activity, char...

Plant stem cell populations, unlike their animal counterparts, do not use cell migration and oriented cell divisions to maintain their size, and therefore require a precise coordination between self-renewing divisions of stem cells, and rates of cell division and differentiation among stem cell progenitors. Shoot apical meristems (SAMs) of higher plants harbor a set of stem cells within the cen...
