We present an empirical application of multispectral laser scanning for monitoring the seasonal and spatial changes in pine chlorophyll (a+ b) content and upscaling the accurate leaf-level chlorophyll measurements into branch and tree level. The results show the capability of the new instrument for monitoring the changes in the shape and physiology of tree canopy: the spectral indices retrieved...

One non destructive method of biomass quantization involves exploiting biophysical parameters of trees such as diameter at breast height (DBH), height, basal area, volume and stocking. Generally, these parameters are estimated through model functions or algorithms which transform a set of remote sensing observations into biophysical measurements. Several studies have investigated the estimation...

Lymphangiomatosis with Gorham-Stout syndrome is a rare disease involving two pathological processes: Infiltration of nonmalignant, aberrant lymphatic vessels into soft and hard tissues and bone lysis. This report will describe a patient suffering from Lymphangiomatosis with external dental cervical resorption that mimics caries lesions. The rate of resorption was found to be related to disease ...

Climate change and population growth risk the world’s food supply. Annual crop yield production is one of most crucial components global Moreover, COVID-19 pandemic has stressed security, production, supply chains. Using biomass estimation as a reliable indicator, space-based monitoring crops can assist in mitigating these stresses by providing product information. Research been conducted to es...

A USDA Natural Resources Conservation Service, Conservation Innovation Grant project coordinated by the United Egg Producers (UEP) conducted concurrent demonstrations in Iowa and Pennsylvania (PA) at commercial laying hen facilities. The goal was to document manure nutrient and gas emission improvements through the use of dried distiller’s grain with solubles (DDGS) diets and/or other dietary m...

In this experiment, the effect of prebiotic Bio-Mos® (MOS) and types of feed formulation (total and digestible amino acids) were evaluated on performance and the small intestine microflora in laying hens for a duration of 10 wks. A total of 168 Hy line W-36 laying hens, with an initial age of 73 wks, were randomly allocated to 4 dietary treatments, 7 replicates and 6 birds in each replicate. Th...

Many applications that exploit the manufacturing flexibility of additive manufacturing (AM) produce surfaces, primarily internal features, which cannot be measured using conventional contact or lineof-sight optical methods. This paper evaluates the capability of a novel technique to extract areal surface data from micro-focus x-ray computed tomography (XCT) from AM components and then generate ...

introduction: one of the most common problems we confront in orthodontic therapy is periodontal diseases. initial factor which causes these diseases is colonization of anaerobic microorganisms in subgingival plaque. technically, local environmental changes related to orthodontic band and brackets may influence the bacterial species in periodontal plaque. however, it seems necessary to assess va...
