Decapterus Maruadsi

Decapterus maruadsi surimi products were prepared using the thermal treatment methods of boiling (BOI), steaming (STE), back-pressure sterilization (BAC), roasting (ROA), microwaving (MIC), and frying (FRI), respectively. The effect of glutamine transaminase (TGase) addition was also investigated. The moisture distribution, water retention, microstructure, color, fracture constant, protein secondary structure, chemical forces, and flavor components of each sample were determined. The differences in gel and favor characteristics between D. maruadsi surimi products caused by thermal treatment methods were analyzed. The results showed that BOI, STE, and FRI had the largest protein secondary structure transitions and formed dense gel structures with high fracture constant. The kinds of flavour components in BOI and STE were completer and more balanced. The high temperature treatment available at BAC and FRI (110 °C and 150 °C) accelerated the chemical reaction involved in flavor formation, which highlighted the flavor profiles dominated by furans or esters. The open thermal treatment environments of ROA, MIC, and FRI gave them a low moisture content and water loss. This allowed the MIC to underheat during the heat treatment, which formed a loose gel structure with a low fracture coefficient. The addition of TGase enhances the gel quality, most noticeably in the ROA. The aldehyde content of the FRI was enhanced in the flavor characteristic. The effect of adding TGase to enhance the quality of the gel is most evident in ROA. It also substantially increased the content of aldehydes in FRI. In conclusion, different heat treatments could change the gel characteristics of surimi products and provide different flavor profiles. The gel quality of BOI and STE was consistently better in all aspects.

A new lightweight thermal insulation board, containing expanded perlite and inorganic silicate binder with corresponding industrial production procedure was developed. The industrial technology was developed in cooperation between company Trimo d.d. and Faculty of chemistry and chemical technology Ljubljana and among others includes mixing of raw materials, molding, microwave drying and high temperature treatment of the dried board. A new product has low density (130 – 160 kg/m3), good mechanical properties and durability and can be used in various fields where inorganic thermal insulation is required. The current work presents the experimental study of the final process during plate production – high temperature treatment with sintering. During thermal treatment of the board, certain shrinkage is required to obtain sufficient mechanical properties and durability. Controlling the process of high temperature thermal treatment is the key to achieve the right balance between low final density of the board and its good mechanical properties.

The demand of highly effective aluminosilicates such as class F fly ash for use in geopolymer synthesis initiated a strong scientific interest for a design of the quality assessment methods. At the same time, the existing assessment methods apparently differ in key parameters which determine the quality of aluminosilicate. This research was focused on determination of relationship between the key parameters of different assessment methods for different types of low-calcium fly ash with high portion of vitreous phase. The insoluble aluminosilicate portion in fly ash that remained after treatment in aggressive acidic media followed by high-temperature treatment at 1000 °C (or the parameter α) was measured in this study. The experimental data showed a very low correlation (R2=0.34) between parameter α and compressive strength of the fly-ash based geopolymer paste. The correlation factors between such genetic parameters of fly ash as portion of vitreous phase (C), SiO2-bonding degree in vitreous phase (fSi) and parameter α demonstrated dramatically different values: R2 (С-α)=0.01; R2(fSi-α)=0.71; R2 (С-fSi)=0.0, respectively.

Celadon glazes have been investigated by means of ordinary X-ray fluorescence analysis, and X-ray diffraction and X-ray absorption spectra using synchrotron radiation. The tentative glazes are prepared by mixing raw celadon materials of Masuda feldspar, limestone, quartz, and extra-added Fe2O3 of about 1wt% at thermal treatment till about 1300 °C. It is found that the glaze-colors strongly depend on the Fe2O3 amount and the high-temperature treatment under oxidizing and deoxidizing in the used kiln. Especially, the characteristic color of blue-green, white-green-brown, and white-blue-green result from complex hybridized 3d5L and 3d6L bands. The 3d6L hybridization is induced by an electronic exchange interaction between an empty 3d6 orbital of Fe ions and an occupied 2p orbital of surrounding O ions in the (SiO2 - Al2O3 - CaO) basic complex ceramics of glass-state under the deoxidizing thermal treatment.

Forcing Culture

In order to advance blooming from autumn to spring and to evaluate the vegetative and reproductive characteristics of tuberose, the forcing culture was carried out in greenhouse by treatments of temperature (ck, 4 °C, and 30 °C) and GA3 (0, 40, and 80 mg·L1)on corms before planting. The results showed that number of days to flower with corms treated at 4 or 30 °C was reduced and the corm sprouting was enhanced significantly in all planting dates. High temperature treatment made more corms sprouting than cold treatment except the Dec planting. Flowering percentage at 4 °C was enhanced in the Dec planting compared with CK (15 °C). Low temperature treatment significantly reduced length of spikes in Oct planting. The number of florets per spike was decreased significantly by the low or high temperature treatments in both Oct and Dec plantings. There was no difference in floret number under different temperatures except Oct plantings. GA3 had no significant effects on flowering duration when corms were planted at the same dates. GA3 had less influence on growth and flowering of Double compared with the temperature treatment. The quality of cutting flowers was decreased in greenhouse compared with local field production. Therefore, the forcing cultivation of tuberose may be performed with Double and no man-forced winter dormancy of corm treated at 4 °C for 30 days or 30 °C for 15 days before planting.

Structure Of Proteins

The quality of a multi-layered network predicting the secondary structure of proteins is improved substantially by: (i) using information about evolutionarily conserved amino acids (increase of overall accuracy by six percentage points), (ii) balancing the training dynamics (increase of accuracy for strand), and (iii) combining uncorrelated networks in a jury (increase two percentage points). In addition, appending a second level structure-to-structure network results in better reproduction of the length of secondary structure segments.
