In this paper, the authors analyzed the correlation between the microbiological stability of white wines and the content of sulfur dioxide, which influences the main redox processes that take place in the technological stages of the wine. The consecutive, parallel and spontaneous development of several redox processes and their impact on the quality, microbiological and crystalline stability of white wines were examined. The reduction of additive and subtractive technological interventions, of the amounts of adjuvants (sulphurous anhydride) is essential for the production of organic wines. 展开更多

Two magnetic monopole models (i.e., model (I, II)) are presented to discuss the energy resources problem based on magnetic monopole catalytic nuclear decay in massive white dwarfs. We find that the luminosities for most of massive white dwarfs increase as the temperature increases. The luminosities of model (II) are agreed well with those of the observations at relativistic high temperature (e.g., T6=1,10), However, the luminosities of the observations can be five orders of magnitude larger than those of model (I). 展开更多

Green and low carbon promote the application and development of light-weight materials in body-in-white. Large-scale die-casting Al alloy (DCAA) and high-strength thermo-formed steel sheet (TFSS) have put forward higher requirements for the application of joining technology of high-strength steel/Al dissimilar materials. Taking the new die-casting Al alloy body as an example, this paper systematically studies the progress of the latest joining methods of steel/Al dissimilar material with combination of two-layer plate and three-layer plate. By analyzing the joining technologies such as FSPR, RES, FDS and SPR, the technology and process characteristics of steel/Al dissimilar material joining are studied, and the joining technical feasibility and realization means of different material combination of the body are analyzed. The conditions of material combination, material thickness, material strength, flange height, preformed holes and joint spacing for achieving high-quality joining are given. The FSPR joining technology is developed and tested in order to meet with the joining of parts with DCAA and TFSS, especially for the joining of three-layer plates with them. It finds the method and technical basis for the realization of high quality joining of dissimilar materials, provides the early conditions for the application of large DCAA and TFSS parts in body-in-white, and meets the design requirements of new energy body. . 展开更多

The study of the morphology of White Blood Cells (WBCs) further contributes to the clinical diagnosis of blood diseases. In this research paper, we come up with an image segmentation enhancement by combining Fourier Fast Transform on smear blood capture and classical thresholding. The Fast Fourier Transform (FFT) is a very powerful tool in image processing and it was used to segment and extract the WBCs. Our image processing method uses a Fast Fourier Transform combined with filtering and an Inverse Fast Fourier Transform for the extraction and visualization of the high frequency region of the image. In order to remove residual Red Blood Cells acting as noise in the expected result, a final thresholding step is added at the end of the processing. The results presented in this article report the tests performed using our mathematical implementation. Moreover, we were able to detect and differentiate the sub-families of WBCs. 展开更多

The management of diabetes mellitus is based on lifestyle and dietary measures suggesting the consumption of foods with a low glycemic index. The present study was conducted in order to propose food formulas based on white rice and white beans resulting in a lower glycemic response. For this, food formulations based on these foods were first made, in particular the formulation [75% white rice + 25% white beans] and the formulation [50% rice + 50% white beans]. Then, the biochemical composition of white rice, white bean and these two formulations was determined by the usual methods. Finally, their glycemic responses over 120 minutes were studied by the FAO/ WHO 1998 method. The results showed that white rice [100% white rice] had the highest carbohydrate content (54.61%) followed respectively by the formulation [75% white rice + 25% white bean] (45.69%), the white bean [100% white bean] (29.1%) and the formulation [50% white rice + 50% white bean] (26.16%). In terms of glycemic responses, the formulation [50% white rice + 50% white beans] presented the best evolution with a lower peak (6.041 mmol/L) observed at T45<sub>min</sub> and a lower postprandial glycemia (4.872 mmol/ L) at T120<sub>min</sub>. An increase in the proportion of beans is therefore recommended as it may suggest a beneficial metabolic effect. 展开更多
