Opis:
The interface characteristics, bending and impact behavior, as well as fracture characteristics of stainless steel clad plates fabricated by vacuum hot rolling at different rolling temperatures of 1100°C, 1200°C and 1300°C are investigated in detail. The interface bonding strength is gradually increased with the increasing rolling temperature due to the sufficient diffusion behavior of alloy element. The bending toughness and impact toughness are gradually decreased, while the bending strength increase with the increase of the rolling temperature, which is attributed to mechanisms of matrix softening and interface strengthening at high rolling temperature. Due to the weak interface at 1100°C, the bending and impact crack propagation path was displaced by delamination cracks, which in turn lead to reduction in stress intensity of the main crack, playing an effective role in toughening the stainless steel clad plates. Moreover, the impact fracture morphologies of clad plates show a typical ductile-brittle transition phenomenon, which is attributed to the matrix softening behavior with the increasing rolling temperature.

Opis:
Masson pine (Pinus massoniana) is an important species for resin tapping in China. Molecular assisted selection (MAS) has been gradually introduced in to the selection and breeding of masson pine. Until now, the lack of connection between genome information and phenotypic data has hindered the breeding and selection of important chemical compounds of xylem resin. In this study, gas chromatography mass spectrometer (GC-MS) was employed for qualitative and quantitative analysis of chemical compounds of resin collected from 69 masson pine germplasm resources. Then, genome-wide association study (GWAS) was conducted for the terpenoids with higher heritability. A total of 15 primary compounds, including six diterpenes and nine monoterpenes/sesquiterpenes, were detected from xylem resin. By using five GWAS methods, 42 associated SNPs were identified from these masson pines. The P. taeda genome database was used for detecting candidate genes related to the associated SNPs. By using transcriptome data, several members of PKc_like super family, Cytochrome P450, AP2-ERF, F-box, and ABC transporter were found to be highly expressed in the masson pines with higher resin-yielding capacity. The terpenoids associated SNPs can be directly used for MAS. These candidate genes, especially the two F-box members, will contribute to the study of terpenoid biosynthesis mechanisms in the future.

Opis:
The combined influence of silicon content and oxygen concentration on silicon-containing steels was investigated, via a heating route similar to that applied in the industrial reheating process, using a Simultaneous Thermal Analyzer (STA). Four different oxygen concentrations and three different isothermal holding times were designed. The results show that the effect of silicon on the mass gain depends on the oxygen concentration and the oxidation time. The mass gain of low-silicon steel is greater than that of high-silicon steel at 1260°C in the oxygen concentrations of 1.0 vol.% and 2.0 vol.%, even when the isothermal holding time is 90 minutes. However, there is a critical time point for mass gain in oxygen concentrations ≥3.0 vol.%. The mass gain of lowsilicon steel is greater before and smaller after this critical point. The critical time is deferred with decreasing oxygen concentration.

Opis:
Compression is one of the typical parameters measured in material mechanics. In this research, the compression displacement fields on the front and rear surfaces of an epoxy sample are measured by using a tilt depth-resolved wavenumber-scanning Michelson interferometer. The light source is a distributed feedback laser diode, the wavenumber of which can be modulated to about 1.017 × 104 m–1 by the temperature without mode hopping. A random-sampling Fourier transform is designed to evaluate the phase differences before and after the applied loads. Experimental results show that the depth-resolved measurement of the compression displacement field is of high accuracy. It can be used to analyze force propagation inside resin-based composites.

Opis:
This paper is concerned with cluster consensus of linear multi-agent systems via a distributed event-triggered control scheme. Assume that agents can be split into several clusters and a leader is associated with each cluster. Sufficient conditions are derived to guarantee the realization of cluster consensus by a feasible event-triggered controller if the network topology of each cluster has a directed spanning tree and the couplings within each cluster are sufficiently strong. Further, positive inner-event time intervals are ensured for the proposed event-triggered strategy to avoid Zeno behaviors. Finally, a numerical example is given to illustrate the effectiveness of the theoretical results.

Opis:
Lignite is well known for its strong hydrophilicity and hard-to-float properties. However, the surface free energy of the solid is made up of two components, that is the Lifshitz-van der Waals and acid-base interaction energy. Differences in these two components between the low ash (lower density) and high ash fraction (higher density) provide a benefit for improving the separation efficiency through introducing surfactants in flotation. In this paper, thermodynamic characterization of three density lignite fractions was measured by a Washburn dynamic method. Combining the Washburn equation and Van Oss-Chaudhury-Good theory, the surface free energy components of three samples were calculated according to the wetting process by n-hexane, diiodomethane, deionized water and ethylene glycol. The Lifshitz-van der Waals part of surface free energy reduced with the coal density increase, especially between fractions of -1.45 g/cm3 and 1.45-1.80 g/cm3, while the Lewis base part increased slightly. The interfacial interaction free energies between the surfactant and lignite in aqueous medium indicated that the low hydrophilic index benefited for the stronger adsorption intensity. Increase of the surfactant Lifshitz-van der Waals component increases the adsorptive intensity on lower density lignite and the repulsive intensity on higher density lignite, which is beneficial for separation.

Opis:
In this study the collecting power of N-oleoyl sarcosine acid towards wolframite and quartz was studied using flotation. The adsorption mechanism was also discussed based on the results from adsorption experiments, zeta potential measurements and infrared spectroscopy study. The flotation results showed that N-oleoyl sarcosine acid showed a good collecting power towards wolframite, and the optimal flotation pH = 7 was obtained. However, the collecting power of N-oleoyl sarcosine acid towards quartz was weak. Therefore, the flotation separation of wolframite from quartz can be performed using N-oleoyl sarcosine acid as a collector. The adsorption tests and electrokinetic studies showed that N-oleoyl sarcosine acid adsorbed only on the wolframite surface. Additionally, the results from the infrared spectroscopy study confirmed that N-oleoyl sarcosine acid is adsorbed on the wolframite surface, and the metal complex (ferriccarboxylate) maybe the major adsorbed species.

Opis:
Mechanical fastening techniques are used extensively in different industry fields for joining various materials in the assembly of components and structures. The use of mechanical clinching is of interest to different industries such as aerospace, automotive, packaging and domestic appliance. This, together with increasing use of light-weight materials, has produced a significant increase in the use of mechanical clinching in light-weight structures in recent years. This paper deals with the mechanical properties and fracture analysis of extensible die clinched joints in the dissimilar metal sheets combinations of titanium sheet material and aluminum sheet material. Tensile-shear tests were carried out to characterize the mechanical properties of different clinched joints made of the dissimilar metal sheets combinations. The normal hypothesis tests were performed to examine the rationality of the test data. The load-bearing capacity and failure modes of different titanium sheets clinched joints were studied. Results showed that most titanium sheets clinched joints failed in the neck fracture mode. Results also showed that the load-bearing capacity of clinch joints with titanium as upper sheets is higher than that of the clinched joints with titanium as lower sheets.

Opis:
Three-dimensional (3D) locally resonant phononic crystals (LRPCs) are studied with the aim of optimising the sub-wavelength band gaps of such composites. By analysing their effective acoustic properties, it has been found that the effective acoustic speed of the composite will drop to zero when local resonance arise, and will increase monotonically when Bragg scattering effects occur. Moreover, if the matrix is a low-shear-speed medium, local resonators can significantly reduce the effective acoustic speed of the composite and, therefore, lower the frequency where Bragg scattering effects occur. Hence, a specific LRPC with alternating elastic and fluid matrices is proposed, whose resonance and Bragg gaps are already close in frequency. The fluid matrix behaves as a wave filter, which prevents the shear waves from propagating in the composite. By using the layer-multiple-scattering theory, the coupling behaviour of local resonance and Bragg scattering band gaps has been investigated. Both gaps are enhanced when they move closer to each other. Finally, a gap-coupled case is obtained that displays a broad sub-wavelength band gap. Such proposal excels at the application of underwater acoustic materials since the arrangement of structure can be handily adjusted for tuning the frequency of coupled gap.

Opis:
Assuming independently but identically distributed sources, the traditional DOA (direction of arrival) estimation method of underwater acoustic target normally has poor estimation performance and provides inaccurate estimation results. To solve this problem, a new high-accuracy DOA algorithm based on sparse Bayesian learning algorithm is proposed in terms of temporally correlated source vectors. In novel method, we regarded underwater acoustic source as a first-order auto-regressive process. And then we used the new algorithm of multi-vector SBL to reconstruct the signal spatial spectrum. Then we used the CS-MMV model to estimate the DOA. The experiment results have shown the novel algorithm has a higher spatial resolution and estimation accuracy than other DOA algorithms in the cases of less array element space and less snapshots.

Opis:
Clinching is an effective joining technique for lightweight sheet materials that are difficult or impossible to weld. A theoretical model for clinched joints in metal sheets was established and a design method for improving joint strength by selecting different clinching tools was proposed. The analytic model is defined as a function of the neck-thickness and the undercut, which are the key parameters of joint geometry. Based on the analytic model, the design method of clinched joint strength that can satisfy required strength was proposed. Clinching experiments were conducted with 2.00 mm thick aluminium alloy 5052 sheets. Various conditions were used during the clinching process to validate the joint strength model. Tensile-shear strength of clinched joints was measured by a servo-hydraulic testing machine. The calculated joint strength was in good agreement with the experimental results.

Opis:
Drought variability of Kyrgyzstan is an important component of climate change of high Asia. Long-term information about the history of drought is, however, limited because the instrumental records are short. Here, we developed three chronologies for juniper trees (Juniperus turkestanica) under different microsite conditions in the Gulcha River Basin, Kyrgyzstan. The three chronologies (GUL, GUR and GUD) were compared with climate data which covered the study area. Growth of the GUL site correlates positively with May–June precipitation of the current growing season and September precipitation of the previous year, but negatively with temperatures of prior July, current May and July. Growth of the GUR site correlates positively with precipitation of current May and September, and negatively with temperature of current June and July. Ring width at GUD site is negatively correlated with temperature of the current May and July, and positively correlated with precipitation of prior December and current September. Response analysis shows that water availability is the main factor limiting the radial growth of juniper trees at the GUL and GUD sites. Based on the relationships derived from climate response analyses, the potential of tree-ring chronologies from this species to provide drought reconstructions in the Gulcha River Basin has been established. The GUL chronology and other moisture sensitive tree-ring series from high Asia capture the recent wetting trend. The records contribute to a growing tree-ring network for high Asia, including sites in China, Kyrgyzstan, Pakistan and Tajikistan.

A spectrum analysis method is used to detect an acceleration signal rapidly. The experimental results show that the thin-core fiber-based fiber-optic accelerometer has a minimum detectable acceleration of 3.3×10–3g (g – gravitational acceleration), and a wide frequency response range from 10 to 1200 Hz. Moreover, the proposed accelerometer exhibits the advantages of low cost, simple structure and easy fabrication.

Due to the increased use of lightweight sheet materials, there has been a significant increase in the use of self-pierce riveting. This paper deals with the strength and fracture mechanism of single-lap self-pierce riveted joints. The online window technique was introduced in the single-lap self-pierce riveting processes for evaluating the quality of joints. Signals obtained from sensors were amplified and transferred to the data acquisition system which measures, processes and saves the signals. Monotonic tensile tests were carried out to measure the ultimate tensile strengths for the single-lap self-pierce riveted joints. For investigating the fracture mechanism of the single-lap self-pierce riveted joints, the electrolytic polishing and anode film coating were used for dealing with the cross-section. The differential interference contrast method was used for observing the micro-structure of the cross-section of the joints. The distribution of the hardness in the cross-section of the single-lap self-pierce riveted joints was also studied. The normal hypothesis tests were performed to examine the rationality of the test data.

Pharmaceutical industry is forced to develop new pharmacologically active molecules. Like other plants, mosses are considered to be potential source of new biologically active compounds. The present study was designed to evaluate the The antimicrobial and antioxidant activities of extracts obtained from some moss species in Turkey antimicrobial and antioxidant activity of 8 moss species: Hypnum cupressiforme, Homalothecium sericeum, Thuidium delicatulum, Homalothecium lutescens, Homalothecium nitens, Leucodon sciuroides, Ctenidium molluscum, and Eurhynchium striatulum obtained from Turkey. Methods: The antimicrobial activity of extracts was investigated against four Gram (+) and six Gram (–) bacterial strains and three tested fungi. Total phenolic content (TPC), cupric reducing antioxidant capacity (CUPRAC), ferric reducing antioxidant power (FRAP), and DPPH radical scavenging activity assays were applied to determine the antioxidant activity. All moss extacts were found to be active against all the organisms except Homalothecium nitens. Especially, H. sericeum and E. striatulum showed the best antioxidant activity. The obtained results show that mosses may be used as possible natural antioxidant, antimicrobial agents to control various human, animal and plant diseases.
Przemysł farmaceutyczny wciąż poszukuje nowych związków aktywnych. Podobnie jak inne rośliny, również mchy uważa się za potencjalne źródło nowych związków biologicznie czynnych. Przedstawione badania miały na celu określenie aktywności przeciwdrobnoustrojowej i przeciwutleniającej ośmiu gatunków mchów rosnących w Turcji: Hypnum cupressiforme, Homalothecium sericeum, Thuidium delicatulum, Homalothecium lutescens, Homalothecium nitens, Leucodon sciuroides, Ctenidium molluscum i Eurhynchium striatulum. Działanie przeciwdrobnoustrojowe wyciągów badano w stosunku do czterech szczepów bakterii Gram (+) i sześciu Gram (–) oraz w stosunku do trzech gatunków grzybów. Działanie przeciwutleniające badano oznaczając sumę zawartości związków fenolowych (TPC), zdolność redukowania miedzi (CUPRAC), zdolność redukowania jonów żelaza (FRAP) i oznaczając działanie przeciwutleniające z użyciem rodnika DPPH . Wszystkie badane wyciągi z mchów (za wyjątkiem Homalothecium nitens) wykazywały aktywność przeciwdrobnoustrojową w stosunku do testowanych mikroorganizmów. Najsilniejsze działanie przeciwutleniające wykazały wyciągi z H. sericeum i E. striatulum. Otrzymane wyniki wskazują, że można traktować mchy jako potencjalne naturalne źródła substancji antyoksydacyjnych i przeciwdrobnoustrojowych do zwalczania chorób ludzi, zwierząt i roślin.
