Opis:: Tartary buckwheat seed and especially its sprouts are rich in D-chiroinositol (DCI). The research was to evaluate when DCI was most accumulated in tartary buckwheat sprouts. In addition, we explored the activity and expression pattern of α-galactosidase during tartary buckwheat seed germination. The results showed that DCI contents steadily increased at early stage of germination and reached the highest level of 33.42 μg/seed at 24 h during the 72 h trail. However, the total fagopyritol contents sharply decreased from 214.6 μg/seed to 46 μg/seed at the end of the germination. The activity of acid α-galactosidase increased gradually to the peak of 0.36 nkat/seed at 24 h after the primed seed imbibition. We cloned the gene fragment of α-galactosidase in tartary buckwheat for the first time. The deduced amino acid sequence is 93% identical to that of P. vulgaris. The quantitative PCR result of gene expression pattern was consistent with its enzyme activity during seed germination.

Opis:: The parenchyma cellulose isolated from bagasse pith was used as an alternative resource for preparation of water-soluble cellouronic acid sodium salt (CAS). The influence of ultrasound treatment on the cellulose was investigated for obtaining CAS by regioselective oxidization using 4-acetamide-TEMPO and NaClO with NaClO₂ as a primary oxidant in an aqueous buffer at pH 6.0. The yield, carboxylate content and polymerization degree (DP) of CAS were measured as a function of ultrasonic power, agitating time and cellulose consistency by an orthogonal test. The ultrasound-treated conditions were further improved by discussion of ultrasonic power, the most important factor influencing the yield and DP. An optimized CAS yield of 72.9% with DP value (DPv) of 212 was found when the ultrasonic strength is 550 W, agitating time is 3 h and cellulose consistency is 2.0%. The oxidation reactivity of cellulose was improved by ultrasonic irradiation, whereas no significant changes in crystallinity of cellulose were measured after ultrasonic treatment. Moreover, the ultrasound treatment has a greater effect on yielding CAS from parenchyma cellulose than from bagasse fibrous’ one. The CAS was further characterized by Fourier transform infrared spectroscopy (FT-IR) and Scanning electron microscopy (SEM).

Opis:: Based on studying the constitution of yarn system and the geometric modality of relevant yarns in the multi-axial warp-knitted structure, 3D solid models of the loop yarns, insertion yarns and chopped strand mat in modern multi-axial warp-knitted fabrics were built to reflect the geometric structures of the three items by using NURBS curves and the principle of curved surfaces. Besides, OpenGL was employed to explore the corresponding 3D computer simulation system under the condition of VC++.NET, which could simulate the geometric model of multi-axial warp-knitted fabric. Meanwhile, through the selection of the unit cell of the fabric, the unit cell model of modern multi-axial warp-knitted fabric with chopped strand mat was developed and the relation between geometric parameters and process variables was deduced. The theoretical fibre volume fraction formula of modern multi-axial warp-knitted fabric with chopped strand mat was obtained as well. Furthermore, by using different specifications of fabric as samples, theoretical and experimental values of the fibre volume fraction were compared. The results revealed that there was good agreement between the theoretical and experimental values, which proved that the model was scientific and practical.
Na podstawie badań struktury systemu przędz i geometrycznej modalności odpowiednich przędz w wieloosiowej dzianej strukturze osnowowej opracowano modele brył 3D przędz pętli, przędz wprowadzanych i struktur z włókien odcinkowych we współczesnych wieloosiowych dzianinach osnowowych w celu zobrazowania ich geometrycznych struktur dzięki zastosowaniu krzywych NURBS i reguł dotyczących zakrzywionych powierzchni. Oprócz tego zastosowano program OpenGL dla zbadania systemu symulacji komputerowej 3D przy warunkach VC++.NET, co pozwala na symulację geometrycznego modelu wieloosiowych dzianin osnowowych. Jednocześnie dzięki selekcji komórki podstawowej dzianiny opracowano model takiej komórki podstawowej dla konfiguracji wcześniej opisanej. Określono również zależności pomiędzy parametrami geometrycznymi a zmiennymi procesowymi. Uzyskano teoretyczną objętość włókien, następnie korzystając ze specyfikacji różnego rodzaju próbek określono zależności pomiędzy teoretycznymi i eksperymentalnymi wartościami objętości poszczególnych frakcji włókien. Wyniki wykazały, że istnieje zgodność pomiędzy teoretycznymi i eksperymentalnymi wartościami, co oznacza, że opracowany model jest naukowo uzasadniony i możliwy do stosowania w praktyce.

Opis:: A new method using sodium carbonate solution to treat a vanadium-bearing steel slag is proposed. The effects of the particle size, solid-to-liquid ratio, initial concentration of sodium carbonate solution, leaching temperature and stirring speed on the leaching rate of vanadium were investigated. The leaching kinetics of vanadium from the vanadium-bearing steel slag was studied, which indicated that the leaching rate was controlled by the step of diffusion through the solid layer around the unreacted core. The apparent activation energy for the process was 13.75 kJ/mol. By using this process, vanadium could be extracted effectively with the leaching rate of more than 80%.

Opis:: The Aselliscus Stoliczkanus bat, studied here, has intricately shaped structures surrounding the nostrils. These structures are hypothesised to have influence on animals’ acoustic radiation patterns. Using micro-tomography scanning technique, a 3D digital model of the noseleaf is reconstructed and biosonar beam pattern is analysed using a finite element method based on the 3D noseleaf model. The present research focuses on the conspicuous furrows in noseleaf, and our analysis allows to conclude the followings: a) structural details in noseleaf of Aselliscus Stoliczkanus bat can produce acoustic effects even if it is not adjacent to the nostrils, b) the furrows possess frequency-selective characteristics, c) the furrows have the function to manipulate the direction and width of the outgoing ultrasound wave.

Opis:: Based on the concept of circular economy, a novel method of industrial organic wastewater treatment by using adsorption on coal is introduced. Coal is used to adsorb organic pollutants from coking wastewaters. After adsorption, the coal would be used for its original purpose, its value is not reduced and the pollutant is thus recycled. Through systemic circulation of coking wastewater zero emissions can be achieved. Lignite, coking coal and anthracite were used as adsorbents in batch experiments. The quinoline removal efficiency of coal adsorption was investigated. The coking coal and anthracite exhibited properties well-suited for adsorption onto both adsorbents. The experimental data were fitted to Langmuir and Freundlich isotherms as well as Temkin, Redlich–Peterson (R-P) and Dubinin-Radushkevich (D-R) models. Both Freundlich Isotherm and D-R model provided reasonable models of the adsorption process. The thermodynamic parameters of quinoline adsorption on coking coal were calculated. The thermodynamic parameters indicated that the adsorption process is exothermic and is a physical adsorption. The △S° value indicated that the adsorption entropy decreased because the adsorbate molecule was under restrictions after it adsorption on the coal surface. The coal adsorption method for removing refractory organic pollutants is a great hope for achieving zero emission waste water for a coking plant.

Opis:: A new technique for pretreatment of coking wastewater is introduced based on the concept of circular economy. Coal is fed into a coking system after adsorption. This study validates the feasibility of using coking coal to adsorb organic pollutants in coking wastewater. The sorption kinetics and equilibrium sorption isotherms of coking coal for removal of chemical oxygen demand (COD) and phenol from coking wastewater was also discussed in this paper. Gas chromatograph/mass spectroscopy (GC/MS) was used to detect changes in the quality of coking wastewater. The results showed that when coking coal dosage was 120 g/dm3, 65% of COD and 34% of phenol in waste water can be removed after 40 min of agitation. The surface functional groups of coking coal before and after adsorption were observed with a Fourier transform infrared spectrometer. The kinetics of COD and phenol adsorption from coking wastewater by coking coal fitted the pseudo second-order model. The adsorption process of coking coal can be classified into two categories, namely, rapid and slow. The Freundlich isotherm provided a better fit with all adsorption isotherms than the Langmuir isotherm. Coking coal could be a suitable low-cost adsorbent for recalcitrant organic pollutants.

Opis:: In view of the fact that the design of jacquard warp knitting patterns is time-consuming, this paper proposes a rapid segmentation method to divide the multi-textural regions of jacquard warp-knitted fabric which could be used for automatic identification of fabric patterns to improve the efficiency of design. After pretreatment, the images scanned were decomposed by a two-layer two-dimensional wavelet transform and the standard deviations of five channels were extracted as the eigen values. Then, after giving the cluster centers, a multi-channel clustering was made combined with a K-means clustering algorithm. Finally the removal of noises caused by classification errors was needed , after which an accurate identification image was obtained. The experiments show that this method can achieve automatic texture segmentation of jacquard warp-knitted fabric with more than three textural regions. The identification results have high regional consistency, and the segmentation accuracy is up to 92%. The method can also adapt to a variety of mesh regions. Besides this, the approach is fast and can simplify craft personnel’s traditional process of pattern tracing classification when it is combined with CAD. Through this method, the efficiency of jacquard warp-knitted product designing can be improved a lot.
Biorąc pod uwagę, że określenie wzorów żakardowych dzianin osnowowych jest czasochłonne, zastosowano metodę szybkiej segmentacji wzorów dla wydzielenia wielostrukturalnych rejonów dzianin, które mogłyby zostać wykorzystane dla automatycznej identyfikacji wzorów dzianin i usprawnieniu procesu projektowania. Po wstępnej obróbce zeskanowane obrazy zostają podzielone poprzez dwuwarstwową, dwuwymiarową transformacje typu „wavelet”, następnie określa się odchylenia standardowe dla pięciu kanałów i ekstrahuje się jako wartość własną. Następnie przeprowadza się wielowarstwową analizę klastrów opartą na specjalnym algorytmie. W końcu usuwa się szumy spowodowane przez błędy klasyfikacyjne co pozwala na dokładną identyfikację obrazów. Eksperymenty wykazują, że opracowana metoda pozwala na automatyczną segmentację struktury osnowowych dzianin żakardowych z więcej niż trzema regionami strukturalnymi. Opracowana metoda zapewnia identyfikację z dokładnością do 92% i znacznie usprawnia proces projektowania dzianin żakardowych.

Opis:: Korean arborvitae (Thuja koraiensis) is an evergreen shrub or small tree native to Korea and the extreme Changbai Mountain of China threatened by habitat loss. Due to the limited genomic sources of Ko- rean arborvitae, it is important to explore transcriptome to understand this economically important plant. We used RNA-seq technology to characterize the transcriptome of root, stem and leaf in Korean arborvitae, respectively. Based on the bioinformatics analysis of assembled transcriptome data, transcriptional path- ways and differentially expressed genes (DEGs) were identified. There were 152.26 million reads generated, and 446,568 unigenes with a mean size of 423.51 nt obtained via de novo assembly. Of these, 204,091 unigenes (45.70%) were further annotated by comparison to public protein databases. A total of 63,495 unigenes (14.22%) were associated into 130 pathways by searching against the KEGG database. DEGs analysis identified 11,890, 5,900 and 10,136 DEGs from the comparison of root vs. stem, root vs. leaf and stem vs. leaf, respectively. Besides, photosynthesis, plant hormone signal transduction and metabolism and biosynthesis of sugar and amino acids were changed in different tissues. We obtained 446,568 unigenes in Korean arborvitae and 11,890, 5,900 and 10,136 DEGs from the compar- ison of root vs. stem, root vs. leaf and stem vs. leaf, respectively. These results will aid in understanding and carrying out future studies on the molecular basis of Korean arborvitae and contribute to future artificial production and applications.

Opis:: The optical gradient force distributions in focal plane of cosh-Gaussian beams with sine-azimuthal variation wavefront and half space phase modulation were investigated. Results show that optical gradient force distributions can be affected considerably by the phase retardation of half-space phase modulation, of a phase parameter that indicates the phase change frequency on an increasing azimuthal angle, and beam parameters in cosh terms of the incident beams. Many gradient force patterns occur, including cross-shape, multiple optical trap arrays, multiple-trap wheel, and many kinds of gradient force lines and curves. Symmetry of the whole gradient force pattern can also be altered remarkably. Above results may find wide applications in optical trapping systems.

An attempt was made to find the rate-limiting step involved in the adsorption processes. Both boundary-layer diffusion and intraparticle diffusion are likely involved in the rate-limiting mechanisms. Effect of pH on coal adsorptions by coking coal was investigated. The process of quinoline adsorption on coal was researched. The coal adsorption method for removing refractory organic pollutants is a great hope for achieving wastewater zero emission for coking plants.

Opis:: The normal modes cannot be extracted even in the Pekeris waveguide when the source-receiver distance is very close. This paper introduces a normal mode extraction method based on a dedispersion transform (DDT) to solve this problem. The method presented here takes advantage of DDT, which is based on the waveguide invariant such that the dispersion associated with all of the normal modes is removed at the same time. After performing DDT on a signal received in the Pekeris waveguide, the waveform of resulting normal modes is very close to the source signal, each with different position and amplitude. Each normal mode can be extracted by determining its position and amplitude parameters by applying particle swarm optimization (PSO). The waveform of the extracted normal mode is simply the waveform of the source signal; the real waveform of the received normal mode can then be recovered by applying dispersion compensation to the source signal. The method presented needs only one receiver and is verified with experimental data.

Opis:: It is generally assumed that plants can respond to varying degrees of physical damage by growth compensation via resprouting, and resprouting is a key functional trait in many species. Few studies have investigated how grass and shrub species distributed in moving dunes and semifixed dunes in semiarid areas respond to the combined effects of temperature and shoot removal. Medicago sativa, Artemisia ordosica, and Artemisia sphaerocephala plants were grown in a glasshouse for 8 weeks at air temperatures of 10/20°C, 12.5/22.5°C, 15/25°C, and 17.5/27.5°C (night/day) and were subjected to treatments of removing all leaves (LR), removing all leaves followed by cutting at half the plant height (HC), and removing all aboveground tissue (WC). The species, temperature, and damage extent had significant effects on the shoot number, leaf mass ratio, leaf area ratio and ratio of belowground to aboveground dry matter, and the species had a significant effect on the net assimilation rate, specific leaf area, and total biomass. The three species grew well under the HC and LR treatments, and high temperatures (15/25°C and 17.5/27.5°C) significantly promoted the regrowth of the three species. Medicago sativa grew faster than the two Artemisia species. Medicago sativa can be used for fertilizing or vegetation restoration in unimportant conservation areas, and the two Artemisia species can be effectively used for vegetation restoration in the Mu Us Sandland. Due to the low labor costs and the local climate conditions, plants should be clipped before the beginning of the main growing season (end of May or early June) to ensure rapid growth.

Opis:: Cold protective clothing was studied in 2 European Union projects. The objectives were (a) to examine different insulation calculation methods as measured on a manikin (serial or parallel), for the prediction of cold stress (IREQ); (b) to consider the effects of cold protective clothing on metabolic rate; (c) to evaluate the movement and wind correction of clothing insulation values. Tests were carried out on 8 subjects. The results showed the possibility of incorporating the effect of increases in metabolic rate values due to thick cold protective clothing into the IREQ model. Using the higher thermal insulation value from the serial method in the IREQ prediction, would lead to unacceptable cooling of the users. Thus, only the parallel insulation calculation method in EN 342:2004 should be used. The wind and motion correction equation (No. 2) gave realistic values for total resultant insulation; dynamic testing according to EN 342:2004 may be omitted.
