T-pattern analysis for the study of temporal structure of animal and human behavior : a comprehensive review
2014
A basic tenet in the realm of modern behavioral sciences is that behavior consists of patterns in time. For this reason, investigations of behavior deal with sequences that are not easily perceivable by the unaided observer. This problem calls for improved means of detection, data handling and analysis. This review focuses on the analysis of the temporal structure of behavior carried out by means of a multivariate approach known as T-pattern analysis. Using this technique, recurring sequences of behavioral events, usually hard to detect, can be unveiled and carefully described. T-pattern analysis has been successfully applied in the study of various aspects of human or animal behavior such …
Multivariate regression analysis applied to the calibration of equipment used in pig meat classification in Romania.
2016
This paper highlights the statistical methodology used in a dissection experiment carried out in Romania to calibrate and standardize two classification devices, OptiGrade PRO (OGP) and Fat-o-Meat'er (FOM). One hundred forty-five carcasses were measured using the two probes and dissected according to the European reference method. To derive prediction formulas for each device, multiple linear regression analysis was performed on the relationship between the reference lean meat percentage and the back fat and muscle thicknesses, using the ordinary least squares technique. The root mean squared error of prediction calculated using the leave-one-out cross validation met European Commission (EC…

Formation of fumonisin B(1)-glucose reaction product, in vitro cytotoxicity, and lipid peroxidation on kidney cells.
2010
Fumonisin B(1) (FB(1)) content in corn products decreases during the heating process in foods containing reducing sugars, mainly because of the formation of N-(carboxymethyl)fumonisin B(1). In this study, a rapid method has been developed for the determination of both compounds in corn products using a high-speed blender, Ultra-Turrax, for solvent extraction and liquid chromatography-tandem mass spectrometry. The kinetics of FB(1) degradation and the formation of the Maillard adduct were studied in a model system constituted by corn bread spiked with FB(1) and heated at 160, 180, and 200 degrees C for 3, 6, 10, 15, and 20 min. FB(1) decreased from 0.96 to 0.3 mg/kg and N-(carboxymethyl)fumo…
Effect of the mechanical harvest of drupes on the quality characteristics of green fermented table olives
2015
Background: Because of damage caused by mechanical harvesting, the drupes for table olive production are traditionally hand harvested. Until now, no data have been available on the microbiological and chemical features of mechanically harvested drupes during fermentation. Results: Drupes mechanically harvested and inoculated with Lactobacillus pentosus OM13 were characterized by the lowest concentrations of potential spoilage microorganisms. On the other hand, drupes mechanically harvested and subjected to spontaneous fermentation showed the highest concentration of Enterobacteriaceae and pseudomonads during transformation. The lowest decrease of pH (4.20) was registered for the trials inoc…
Management and Control of the Read Out Processors (tpps) of the Aleph Time Projection Chamber
1989
The readout of the Aleph time projection chamber (TPC) relies on a set of 72 time projection processors (TPPs), which are based on a Motorola 68020 microprocessor running a real-time operating system. The advanced processing capabilities of the TPPs allow them to perform in parallel a number of tasks, both during and outside of data acquisition, which are outlined. The management and control of such a large number of intelligent devices is presented. The discussion covers the hardware configuration of the TPPs; the software running the TPPs; their management, status, and control; exception handling and message logging; and the TPP monitoring tasks. >

Effects of technological processes on enniatin levels in pasta
2015
BACKGROUND Potential human health risks posed by enniatins (ENs) require their control primarily from cereal products, creating a demand for harvesting, food processing and storage techniques capable to prevent, reduce and/or eliminate the contamination. In this study, different methodologies to pasta processing simulating traditional and industrial processes were developed in order to know the fate of the mycotoxin ENs. The levels of ENs were studied at different steps of pasta processing. The effect of the temperature during processing was evaluated in two types of pasta (white and whole-grain pasta). Mycotoxin analysis was performed by LC-MS/MS. RESULTS High reductions (up to 50% and 80%…
Factors affecting the presence of ochratoxin A in wines.
2006
Ochratoxin A (OTA) are synthesized mainly by different species of Aspergillus and Penicillium being its human toxicological effects reflected in different countries due to the consumption of different foods and beverages such as red, white, rose, and special wines. This review presents an overview of the direct (meteorological conditions, grape cultivation, and wine-making techniques) and indirect (latitude, year of production, use of pesticides, presence of spoilage microorganisms, conditions of storage of the harvested grapes, type of maceration, and conditions of fermentation), factors affecting the presence of OTA in wines.
Influence of roasting and different brewing processes on ochratoxin A content in coffee determined by high-performance liquid chromatography-fluoresc…
2008
A rapid and reliable procedure has been developed for the determination of ochratoxin A (OTA) in green and roasted coffee. The method consists of extraction of the sample with methanol-5% aqueous sodium hydrogen carbonate/1% PEG8000 (20:80), followed by immunoaffinity column (IAC) clean-up and, finally, high-performance liquid chromatography (HPLC) determination with fluorimetric detection. Mean recoveries for green and roasted coffee spiked at different levels ranging from 94 and 105% were obtained. The limit of determination (S/N = 3) was 0.032 ng g(-1) and the precision (within-laboratory relative standard deviation) was 6%. The method described has been used to assess the influence of r…
