In many applications, the spectrum is determined by measuring changes in the intensity or frequency of this energy. The types of radiative energy studied include: Electromagnetic radiation was the first source of energy used for spectroscopic studies.

Techniques that employ electromagnetic radiation are typically classified by the wavelength region of the spectrum and include microwave , terahertz , infrared , near-infrared , ultraviolet-visible , x-ray , and gamma spectroscopy. Particles, because of their de Broglie waves , can also be a source of radiative energy. Both electron and neutron spectroscopy are commonly used.

For a particle, its kinetic energy determines its wavelength. Acoustic spectroscopy involves radiated pressure waves.

Dynamic mechanical analysis can be employed to impart radiating energy, similar to acoustic waves, to solid materials.

Nature of the interaction[ edit ] The types of spectroscopy also can be distinguished by the nature of the interaction between the energy and the material. These interactions include: [1] Absorption spectroscopy : Absorption occurs when energy from the radiative source is absorbed by the material.

Absorption is often determined by measuring the fraction of energy transmitted through the material, with absorption decreasing the transmitted portion. The materials necessary to reproduce the Random Forest analysis are available at figshare ABSTRACT Despite recognition that biogeography and individuality shape the function and composition of the human skin microbiome, we know little about how extrinsic and intrinsic host factors influence its composition.

To explore the contributions of these factors to skin microbiome variation, we profiled the bacterial microbiomes of North American subjects ages, 9 to 78 years at four skin surfaces plus the oral epithelium using 16S rRNA gene amplicon sequencing.

We collected subject metadata, including host physiological parameters, through standardized questionnaires and noninvasive biophysical methods. The influence of health factors was strongest on the oral microbiome.

Associations between host factors and the skin microbiome were generally dominated by operational taxonomic units OTUs affiliated with the Clostridiales and Prevotella. A subset of the correlations between microbial features and host attributes were site specific.

To further explore the relationship between age and the skin microbiome of the forehead, we trained a Random Forest regression model to predict chronological age from microbial features. Age was associated mostly with two mutually coexcluding Corynebacterium OTUs.

Book Description

Furthermore, skin aging variables wrinkles and hyperpigmented spots were independently correlated to these taxa. These commensal microorganisms play critical roles in lipid metabolism, colonization resistance to transient organisms, and regulation of the immune system 4.

Available evidence indicates strong body site specificity and individuality of community composition and functional potential, with variation of physiological conditions driving the local microbial communities. For instance, oily surfaces such as the forehead support lipophilic bacteria, whereas dry sites such as the forearm harbor a more diverse community 3 , 5 , — 7.
