Thinning is a forest management activity that regulates the competition between trees within forest. However, effect of different thinning treatments on largely unexplored, especially because difficulty in measuring crown characteristics. This study aimed to investigate how type and intensity affect stem- crown-based based terrestrial laser scanning (TLS) point clouds. The research was conducte...

OBJECTIVES The aim of this study was to assess the optical properties of orthodontic elastic ligatures under the influence of exogenous pigments contained in the daily diet. MATERIAL AND METHODS For the analysis, colorless (clear) elastic segments (ORTHO Organizers, lot 660625A10) were used as received from the manufacturer, and were divided into 8 groups of 3 segments each. Each group was im...

The expression of human tumor-associated antigens CO17-1 A, GA733, BR55-2, CICA 19-9, and CASO and of carcinoembryonic antigen was immunohistochemically studied in the colonie mucosa of 70 SpragueDawley rats. Fifty were treated with 1,2-dimethylhydrazine (DMH) (with EDTA as a vehicle), ten were treated with EDTA only, and ten were untreated normal rats. The tumors were histogenetically divided ...

Endometriosis is a common disease, which affects 5-10% of women in fertile age 1. It can affect multiple organs , such as ovaries, lungs, colon, nasal mucosa and brain 2. Endometriosis of the sciatic nerve is a rare presentation 3 , manifesting as cyclic sciatica, parestesis and pa-resis with loss of deep tendon reflex. We cite a case of sciatica endometriosis and make a review of the literatur...

The present dynamic manufacturing environment has been characterized by a greater variety of products, shorter life-cycles of products and rapid introduction of new technologies, etc. Recently, a new manufacturing paradigm, i.e. Reconfigurable Manufacturing Systems (RMS), has emerged to address such challenging issues. RMSs are able to adapt themselves to new business conditions timely and econ...

BACKGROUND Regional citrate anticoagulation (RCA) is being increasingly used during continuous renal replacement therapy (CRRT) in intensive care units as an alternative to systemic heparin anticoagulation. However, due to its availability in a variety of solutions and dialysis systems, RCA is still considered a complex intervention, possibly leading to confusion and pitfalls in everyday practi...

Given the distance between every pair of 3 control points, and given the angle to every pair of the control points from an additional point called the Center of Perspectivity (P ), find the lengths of the segments joining the P to each of the control points. We call this the “perspective-three-point (p3p) problem”. The corresponding algebraic equation system is called the p3p equation system. S...
