Opis:
This study aimed to investigate the effect of different coating processes on interlayer coating using ProCAST software and identify the preferred coating process so as to prepare an EH40/2205 composite plate with a coating interlayer of Ni-5 Fe-15 Co (wt.%) displaying good performance. The preparation and characterization tests were conducted to analyze the interlayer coating, the diffusion of elements at the bonding interface and the mechanical properties of the hot-rolled composite plate. The results showed that the coating rate increased linearly with an increase in the initial coating temperature, pressure difference and the width ratio of the suction layer. The interlayer coating was complete under the guidance of optimized process parameters, and the test results and simulations confirmed each other. The coated interlayer successfully blocked the diffusion of elements between the bonding surfaces. The tensile strength of the rolled composite plate was 580 MPa, which met the needs of the project. The tensile shear fracture occurred at EH40, which proved that the plate was well bonded.

Opis:
A proof of concept for using paper test as a suitable method in the production of monoclonal antibodies (MAbs) is reported. The paper test which detects antibodies against porcine circovirus type 2 (PCV2) using colloidal gold-labelled capsid protein as the antigen probe was applied exclusively in the screening of anti-PCV2 MAbs. It allowed the detection of 118 single cell clones within 30 min using naked eyes. MAbs with specific binding to authentic epitopes on the virus were selected using a blocking strategy in which the antibody was pre-incubated with PCV2 viral sample before applying to the test paper. Five hybridomas secreting MAbs against the capsid protein were obtained, with only three of them capable of binding to PCV2. The results were validated and confirmed using enzyme-linked immunosorbent assay and immunofluorescence assay. The paper test is simple, rapid, and independent on professional technicians and proves to be an excellent approach for the screening of MAbs against specific targets.

Opis:
The enzyme strictosidine synthase (STR, EC: 4.3.3.2) plays a key role in the biosynthetic pathway of terpenoid indole alkaloid (TIA). It catalyzes the condensation of the tryptamine and secologanin to form 3α(S)-strictosidine, which is the common precursor of all TIAs. In this paper, a STR gene designated as DoSTR (GenBank: KX068707) was first cloned and characterized from Dendrobium officinale with rapid amplified cDNA ends method (RACE). DoSTR has a length of 1380bp with 1179bp open reading frame encoding 392 amino acids. BlastP analyses showed that its amino acid sequence was classified into Str_synth superfamily. qRT-PCR showed that DoSTR was expressed in all tissues tested, with a significantly higher level in flower and the lowest in stem. Four different treatments with MeJA, SA, ABA and AgNO₃, respectively, could induce the DoSTR expression to a different extent. And the effect of MeJA was the most obvious and transcript level of DoSTR induced by MeJA was 20.7 times greater than that of control at 48 hours after treatment. Furthermore, it was found that DoSTR was localized in vacuole through transient expression in tobacco. The characterization and expression of DoSTR can help in further studying the role of DoSTR in the biosynthesis of TIAs in D. officinale. This study may throw light on the alkaloid biosynthesis pathway of D. officinale.

Opis:
Mechanical drying significantly affects the mechanical properties of corn kernels. Improper drying may result in material losses and in a decline in quality due to pressure, collisions, and other factors during subsequent storage and transport operations. A literature survey revealed that at time of writing the characteristics of dried corn kernels have not been systematically and fully studied. In this paper, an orthogonal rotation combination test scheme was designed. Using a multiparameter controllable thin layer drying test bench, corn was dried under different conditions (temperature 30-60°C, relative humidity 30-60%, air velocity 0.46-0.94 m s–1, initial moisture content of corn of 20-30% w.b., tempering ratio 0-3). Then, a texture analyser was used to measure the mechanical properties (rupture force, rupture energy, modulus of elasticity and brittleness) of the dried corn kernels. Relationship models were established for the rupture force, rupture energy, modulus of elasticity and brittleness and drying conditions of corn kernels. An increase in the drying temperature from 30 to 60°C increased the rupture energy, elastic modulus, and brittleness of the corn kernels by 19.11, 11.76, and 4.02%, respectively; an increase in the drying relative humidity from 30 to 60% increased the rupture force, energy, modulus of elasticity and brittleness by 15.07, 13.74, 20.73, and 3.31%, respectively.

Paeonia sect. Moutan is a wide known ornamental plant in the world. The objective of this study was to provide the theoretical basis for scientific preservation and utilization of tree peony resources of Hunan province of China. Simple sequence repeat (SSR) markers were applied to reveal the genetic diversity and relationship of 21 tree peony resources and 45 domestic and foreign tree peony cultivars. Clear bands, the size of which ranged from 115 bp to 379 bp, were detected with 14 primers. In total, 90 alleles were detected and the number of alleles detected with one primer varied between 5 and 13; the number of effective alleles ranged from 1.183 to 2.070; the polymorphism ratio of each locus was 100%. The observed heterozygosity, which ranged from 0.120 to 0.851 with an average of 0.532, was larger than the expected one, which ranged from 0.090 to 0.470 with an average of 0.300. Shannon index ranged from 0.137 to 0.695 and fixation index ranged from −0.332 to −0.869. The results show abundant genetic diversity in tree peony of Hunan province and SSR markers distinguishing homonymous tree peony resources successfully.

Opis:
1,1-Dimethylbiguanidium 1H,1′H-5,5′-bistetrazole-1,1′-diolate (MGBTO), a novel nitrogen-rich energetic salt, was synthesized by cation exchange. Its structure was characterized by elemental analysis, FTIR, NMR, DTA and TG-DTG. Single crystal X-ray diffraction analysis revealed that MGBTO was crystallized in the monoclinic space group C2/c. Thermal analysis demonstrated that its thermal stability extended up to 531.1 K. The nonisothermal kinetic and apparent thermodynamic parameters of the exothermic decomposition of MGBTO were determined by the Kissinger and Ozawa methods. Its detonation velocity and detonation pressure were calculated on the basis of the Kamlet-Jacobs equation and were 6342 m·s–1 and 15.78 GPa, respectively. The impact and friction sensitivities of MGBTO were quantified using standard BAM (10 kg drop hammer) procedures. The results revealed that the salt has good mechanical sensitivity (FS > 120 N, IS > 40 J), thus indicating its potential applications as an energetic material.

Opis:
Canine mammary tumors are the most common neoplasms in intact female dogs. The surgery cannot always solve the problem, chemotherapy are recommend to these patients. However, chemotherapy could always fail because of multidrug resistance (MDR). Through stepwise increasing 5-Fluorouracil (5-FU) concentration in the culture medium, a 5-FU-resistant canine mammary tumor cell line CMT7364/5-FU was established to disclose the molecular mechanism of the drug resistance. Cell morphology, cell sensitivity to drugs, growth curves, expression of proteins, and chemo-sensitivity in vivo were compared between the parental cell line and resistant cell line. As compared it to its parental cell line (CMT7364), CMT7364/5-FU showed different morphology, cross-resistant to other chemo-drugs and a prolonged population doubling time (PDT). The drug efflux pump proteins (ABCB1 and ABCG2) in CMT7364/5-FU were up-regulated. In vivo, the similar result revealed that CMT7364/5-FU cell line was more resistant to 5-FU. In conclusion, a 5-FU-resistant canine mammary tumor cell line (CMT7364/5-FU) was successfully established, it can serve as a good model for researching the mechanism of MDR and screening effective agents to reverse drug resistance.

Opis:
The flotation performance of sodium petroleum sulfonates with different molecular weights was evaluated for flotation of a kyanite ore, by investigating valuable mineral recovery-grade, flotation kinetics and gangue entrainment. The results indicated that the higher molecular weight of agent, the higher final cumulative kyanite recovery was, with the maximum value of 72% being obtained with KY-3 with the molecular weight of 438. The final cumulative kyanite grade initially increased, and then decreased with the molecular weight increasing. In other words, the maximum final cumulative kyanite grade (i.e. 89.05%) was obtained with KY-2 with the molecular weight of 392. The kyanite flotation kinetics followed the first order kinetics well, while the modified flotation rate constant showed a decreasing trend after the initial increase as the molecular weight increased. In addition, the overall entrainment degree decreased with decreasing molecular weight of sodium petroleum sulfonates. The use of KY-2 in kyanite flotation was an attractive option in comparison with KY-1 and KY-3.

Opis:
The opening unit is an important device in a rotor spinning unit to comb fibres and remove trash. In this paper, numerical simulation is carried out to study the flow structure in the rotor spinning channel and the trash removal process in the trash removal unit. Firstly the effect of the opening unit on the airflow field in the rotor channel is investigated by singlephase simulation. The result shows that the effective area for fibre conveyance enlarges as the absolute value of negative pressure at the outlet increases, while it decreases as the opening roller speed increases. However, the effect of the negative pressure and the opening roller speed on the length of the vortex in the axial direction is quite small. Secondly the trash separation process in the trash removal unit is simulated using the Discrete Phase Model (DPM). Suitable rotational speeds of particles of different diameters are acquired. These results could provide a valuable reference for parameter selection in the trash-removal process.
Jednostka otwierająca jest ważnym urządzeniem w przędzarce rotorowej służącym do rozczesywania włókien i usuwania odpadów. W artykule przeprowadzono symulację numeryczną mającą na celu zbadanie struktury przepływu w kanale przędzalniczym wirnika oraz procesu usuwania odpadów. Wpływ jednostki otwierającej na pole przepływu powietrza w kanale wirnika badano symulacją jednofazową. Wyniki wykazały, że efektywny obszar transportu włókien powiększa się, gdy wartość bezwzględnej wartości ujemnego ciśnienia na wylocie wzrasta, a zmniejsza się wraz ze wzrostem prędkości wału otwierającego. Jednakże wpływ podciśnienia i prędkość wału otwierającego na długość wiru w kierunku osiowym jest stosunkowo niewielka. Stwierdzono także, że proces separacji odpadów w jednostce usuwania odpadów jest symulowany przy użyciu modelu dyskretnego fazy (DPM). Otrzymuje się odpowiednie prędkości obrotowe cząstek o różnych średnicach. Wyniki te mogą stanowić cenny punkt odniesienia dla wyboru parametrów w procesie usuwania odpadów.

Opis:
The purpose of this paper was to develop an intelligent recognition system consisting of a feature reduction method combining cluster and correlation analyses, and a probabilistic neural network (PNN) classifier to identify different types of hip shape from 3D measurement for each person. Firstly 28 items reflecting lower body part information of 300 female university students aging from 20 to 24 years were selected. The feature reduction method was employed to extract typical indices. Secondly hip shapes were subdivided into five types by a K-means cluster and analysis of variance (ANOVA). Finally the PNN was then trained to serve as a classifier for identifying five different hip shape types. The average classification accuracy of the scheme proposed was 97.37%, and its effectiveness was successfully validated by comparing with the BP and Support Vector Machine (SVM) scheme. Thus an intelligent recognition system was developed to make hip shape type classification of high-precision and time saving.

Wyselekcjonowano 28 przypadków odzwierciedlających dolną część sylwetki 300 studentek w wieku od 20 do 24 lat. Zastosowano metodę redukcji poszczególnych właściwości dla wybrania typowych wskaźników. Następnie kształt bioder podzielono na 5 typów za pomocą algorytmu klastrowego i systemu ANOVA (analiza wariancji). Następnie przeprowadzono trening sieci neuronowej aby mogła posłużyć jako klasyfikator identyfikacji 5 różnych kształtów bioder. Przeciętna dokładność klasyfikacji proponowanego systemu wynosiła 97,37%, a efektywność była sukcesywnie sprawdzana przez porównanie schematów BP i SVM. W ten sposób stworzono inteligentny system rozpoznania typu kształtu bioder o dużej precyzji, pozwalający na oszczędność czasu.

Opis:
Porcine reproductive and respiratory syndrome virus (PRRSV) is an important swine pathogen, causing huge economic losses each year worldwide. Immunization with vaccines containing the glycoprotein 5 (GP5) of PRRSV is the main measure to induce neutralizing antibodies and control the disease. Here, we developed a GP5 protein-based ELISA for detecting antibodies against PRRSV. The overall yield of purified GP5 in E. coli flask culture was more than 45 mg/L cell culture. Western blot and IFA indicated that the GP5 protein was highly immunogenic. After optimization and validation with IDEXX PRRS using 566 clinical sera, the DSN, DSP, and accuracy of GP5-ELISA were 81.39%, 75.96%, and 80.39%, respectively. Besides, GP5-ELISA is highly specific, showing no cross-reactions with sera against other important swine pathogens. Hence, GP5 is a good diagnostic antigen and the GP5 protein-based ELISA has the potential to be used in the field

A microbial consortium OP-1 was enriched from a pesticide production plant and spread cultivated on various food waste (FW) culture media. Results indicated that OP-1 can efficiently degrade organophosphorus pesticides (OPs): isocarbophos, dimethoate and dichlorvos (DDVP). The microbial consortium obtained from the spreading cultivation using FW culture maintained certain degradation capacity of OPs. However, it was decreased after spreading cultivation, probably due to the change of microbial community structure. The finding of this study provided scientific supporting for the development of microbial degradation technique for the environmental remediation.

We present a new dual-wavelength quantitative measurement approach that can be employed for simultaneously measuring both the refractive index and the thickness of the homogenous specimen. This method is realized by dual-wavelength in-line phase-shifting digital holography, and then the phase images are obtained by using four-phase step algorithm for each wavelength separately. Based on computer simulation technology, the feasibility and the effectiveness of our proposed method are demonstrated by comparing our simulation results with the experimental results of the spherical silica bead and the red blood cell, respectively. Our work will provide some guidance in the experimental research for transparent phase objects.

Opis:
A new water-soluble ionic polyacetylene was synthesized by the acid-catalyzed polymerization of 2-ethynylpyridine using acrylic acid. The polymerization proceeded well to give a high yield of polymer. The acetylenic C ≡ C bond stretching (2110 cm¯¹) and acetylenic ≡ C-H bond stretching (3293 cm¯¹) peaks of 2-ethynylpyridine monomer were not seen in the FT-IR spectrum of polymer. The electro-optical and electrical properties of the ionic polyacetylene were measured and discussed. The resulting polymer showed strong maximum at 513 nm in the UV-Visible absorption, which is corresponding to photon energy of 2.42 eV. The energy gap width of polymer was estimated to be of 2.08 eV. It was observed that the electrochemical process of polymer is reproducible in the potential range of -1.80 to 1.60 V vs Ag/AgNO₃. HOMO and LUMO levels of polymer were 4.85 eV and 2.77 eV, respectively.
