"OLD AND LOW-COST SENSOR" FOR MICROPHOTOGRAMMETRY. CASE STUDY: THE EMPEROR <i>MAXIMIANUS HERCULEUS</i>' MEDALLION AT THE CORRER MUSEUM (VENICE)
Abstract. The microphotogrammetric survey of the roman emperor Maximianus Herculeus' medallion, described in this report, demonstrated that, despite the use of an "old" and, nowadays, "low cost" camera sensor it is still possible to obtain a detailed 3D textured model useful for different scientific purposes and virtual enhancement. Here are presented the photogrammetric results reached with the selection of the best solutions in terms of number of images, in order to speed up the entire photogrammetric workflow and pursue the goals previously explained. This medallion is one of the most important examples of roman medallions which belongs to the numismatic collection stored at the Correr Museum in Venice. Its 3D survey was developed as a parallel step of a main project which aims to acquire in three-dimensions, with a structured light scanner, the complete roman collection of medallions. This digitization project proposes to record the volumetric information of these small archaeological remains and to realize an online virtual gallery in the web site of the museum (using 3DHOP, an open source web viewer developed by the Visual Computing Lab of the CNR-ISTI of Pisa). At the end of the microphotogrammetric workflow, a distance analysis was computed to highlight the differences between the meshes obtained with a photogrammetric approach and a structured light scanner
Experimental and theoretical study of the fluorescence emission of ferulic acid: Possible insights into the fluorescence properties of humic substances
Pengaruh Kompensasi Dan Lingkungan Kerja Terhadap Loyalitas Karyawan (Studi Kasus PT. Capella Dinamik Nusantara Cab. Kandis)
This study aims to determine the effect of Compensation and Working Environment Employee Loyalty (Case Study PT. Capella Dinamik Nusantara Cab. Kandis). Compensation as a variable (X1), Environmental Working as a variable (X2) and employee loyalty as a variable (Y).The method in this research is descriptive and quantitative with program SPSS, where samples were used that all employees as many as 25 respondents. To determine the sample, this study used census techniques. Data collection through questionnaires.The study concluded that the variable compensation positive effect on employee loyalty, work environment positive effect on employee loyalty and significant influence between compensation and work environment on employee loyalty

Fracture toughness and material strength are the only parameters required to operate the criterion. This paper provides a formulation of the criterion speci c to blunt notches and further examines the capability of the criterion for samples weakened by U-notches. Predictions are compared to signi cant experimental results from U-notched samples that were subject to mixed-mode fracture. Good agreement is demonstrated, justifying and substantiating the theory
HEV in the pork food chain in United Kingdom
Hepatitis E virus (HEV) is responsible of acute viral hepatitis in people and it is endemic in developing countries where it is transmitted mainly through faecal contamination of drinking water. Some of the cases in developed countries are autochthonous

Biomolecules responsible for the total antioxidant capacity (Tac) of human plasma in healthy and cardiopathic individuals: A chemical speciation model
(1) Background: Much effort has been expended to investigate the antioxidant capacity of human plasma, attempting to clarify the roles of both metabolic and food substances in determining defenses against oxidative stress. The relationship between the total antioxidant capacity (TAC) and the concentrations of redox-active biomolecules in the human plasma of healthy and cardiopathic individuals was investigated in the present study to develop a chemical speciation model. (2) Methods: Plasma was collected from 85 blood donors and from 25 cardiovascular surgery patients. The TAC was measured using the CUPRAC-BCS (CUPric Reducing Antioxidant Capacity — Bathocuproinedisulfonic acid) method. Biomolecule concentrations were determined via visible spectrophotometry or HPLC/RP techniques. The relationship between the TAC and the concentrations was defined by applying a multiple regression analysis. The significance of the variables was first tested, and chemical models were proposed for the two datasets. The model equation is βTAC=∑iβi·Ai, where βi and [Ai] are the electronic exchange and the molar concentrations of the ith antioxidant component, respectively. (3) Results: The major contributions to the TAC, ~80%, come from endogenous compounds in both healthy and cardiopathic individuals, whereas the contributions from exogenous compounds were different between the two datasets. In particular, γ-tocopherol showed a different role in the chemical models developed for the two groups
