Opis:
Charging operations of a compact Tesla transformer were experimentally investigated, in single-shot and rep-rate (50 pps for 1 s) modes, respectively. The charging limitations were also explored. The experimental results were compared and analyzed. The maximum secondary charging voltages of the Tesla transformer were measured to be 380 kV and 300 kV in single-shot and rep-rate modes, respectively. The RMS pulse-to-pulse instability of the secondary charging voltage is generally less than 10% but increases with the increasing initial voltage across the primary capacitor. Since the secondary capacitor of the Tesla transformer is a pulse forming line (PFL), continued operation is possible if there is breakdown in the PFL. Furthermore, operation can even be continued under occasional breakdown for some pulses, without the effects on the operations of subsequent pulses.

Opis:
Solid particles on the floor, both dry and wet, are common but their effects on the friction on the floor were seldom discussed in the literature. In this study, friction measurements were conducted to test the effects of particle size of solid contaminants on the friction coefficient on the floor under footwear, floor, and surface conditions. The results supported the hypothesis that particle size of solids affected the friction coefficient and the effects depended on footwear, floor, and surface conditions. On dry surfaces, solid particles resulted in friction loss when the Neolite footwear pad was used. On the other hand, solid particles provided additional friction when measured with the ethylene vinyl acetate (EVA) footwear pad. On wet surfaces, introducing solid particles made the floors more slip-resistant and such effects depended on particle size. This study provides information for better understanding of the mechanism of slipping when solid contaminants are present.

Opis:
One of the earliest critical secondary complications of diabetes is the opacification of the eye lens - a condition strictly associated with diabetic cataract. The study presented here was designed to investigate the effect of Ginkgo biloba extract (GbE), rutin and quercetin on streptozotocin (STZ) induced diabetic cataract (DC) rats. Ten weeks after administration of GbE, rutin and quercetin, the opacity of diabetic rats' lenses was graded under a slit lamp. Then, the levels of malondialdehyde (MDA), reduced glutathione (GSH), advanced glycosylation end products (AGEs), and the activities of aldose reductase (AR) were estimated. The DC-induced rats produced less GSH, higher levels of MDA and AGEs as well as elevated AR activity when compared to the normal group. Administration of GbE, rutin and quercetin remarkably inhibited the AR activity, stimulated the production of glutathione, and decreased the levels of MDA and AGEs in the lenses of DC-induced rats, which eventually delayed the progression of lens opacification in diabetic rats to various degrees. Our results revealed that quercetin had the highest significant (P<0.05) potential to delay the progression of STZ-induced diabetic cataract when compared with rutin and GbE. The mechanism dictating this interesting prowess of quercetin might be attributed to its AR inhibitory strength, anti-lipid peroxidation potential and anti-AGEs activity.

Opis:
Fluid inclusions in halite can directly record the major composition of evaporated seawater; however, Ordovician halite is very rare. The Ordovician is a key time during the evolution history because profound changes occurred in the planet’s ecosystems. Marine life was characterized by a major diversification, the Great Ordovician Biodiversification Event and the Late Ordovician Mass Extinction, the first of the “big five” mass extinctions. However, so far there is no data on the Ordovician seawater. Data from the Ordovician-Silurian boundary were available only. In this study, we report the major compositions from Middle Ordovician halite in China to give the exact composition of Ordovician seawater. The basic ion composition (K+, Mg2+, Ca2+, and SO42-) of inclusion brines was established with the use of ultramicrochemical analysis. The data on the chemical composition of the brines in the primary inclusions indicated that the brines were of Na-K-Mg-Ca-Cl (Ca-rich) type, and cover a huge gap in the evolution of seawater chemistry. The chemical composition of the primary inclusion brine in halite confirmed the earlier results for the Cambrian and Silurian halite originating from other salt basins and the previous speculation of “calcite sea” during the Ordovician, indicating a higher potassium content in the Lower Paleozoic seawater than in the seawater of other periods of the Phanerozoic.

Opis:
During the Middle Ordovician, the salt deposits of the Majiagou Formation of the Ordos Basin in North China formed, the halite including various genetic types of fluid inclusion. In this study, fit-testing of primary inclusions was performed to reconstruct the physical and chemical conditions during original halite sedimentation. During the post-sedimentation stage, salt was subjected to elevated temperatures (62-70°C) and pressures of tens of megapascals. From these measurements and mathematical calculations, the gas pressure was identified in the primary fluid inclusions, which allowed us to estimate that the brine column thickness in the salt basin was approximately 40 m.

Opis:
From the perspective of a virtual power plant (VPP) with electric vehicles (EVs), a self-scheduling strategy considering the response time margin (RTM) and state of charge margin (SOCM) is proposed. Firstly, considering the response state of the state of charge (SOC) and charge-discharge state of EVs, a VPP based response capacity determination model of EVs is established. Then, RTM and SOCM indexes are introduced on the basis of the power system scheduling target and the EV users’ traveling demands. The RTM and SOCM indices are calculated and then are used to generate a priority sequence of responsive EVs for the VPP. In the process of the scheduling period and rolling iteration, the scheduling schemes of the EVs in the VPP for multiple time periods are determined. Finally, the VPP self-scheduling strategy is validated by taking an VPP containing three kinds of EV users as an example. Simulation results show that with the proposed strategy, the VPP is able to respond to the scheduling power from the power system, while ensuring the traveling demands of the EV users at the same time.

Opis:
The influence of the variation in water content, sampling location and loading speed on the shearing and across-compression mechanical characteristics of dwarf-denseearly major cotton variety stalks was analysed. The second-order response models of the factors vs. the maximum shear force and critical across-compression failure force were built using the response surface methodology. Besides, the sampling location and water content have a significant influence over the maximum shear force and critical across-compression failure force, especially the sampling location. Both the maximum shear force and critical across-compression failure force reach a theoretical maximum when the water content is 10%, the sampling location is the lower part and the loading speed is 40 mm min-1. When the sampling location is the lower part, optimization is carried out assuming the theoretical minimum of the maximum shear force and critical across-compression failure force as the optimization target. In this case, the loading speed is 20 mm min-1, while the water content is between 30 and 50%. This indicates that the parameter range requires a low power consumption during the crushing of film residue mixtures. The test data can provide some theoretical references for the technical research and equipment development for the crushing of film.

Opis:
The Salt Range Formation in northern Pakistan is globally well-known for its extremely large evaporite deposits dated to the upper Ediacaran–lower Cambrian. This huge evaporite belt formed an area covering present-day parts of India, Pakistan, Iran, Oman, and even South China (~200,000 km2 in South China). Sulphate minerals, including anhydrite and gypsum, can continuously record seawater sulphur isotopic composition. Until now, there was only one dataset reporting the isotopic composition of evaporites in Pakistan. This study reports new data, which points to a strongly positive sulphur isotopic shift (>+30‰, VCDT values) in the Salt Range Formation in Pakistan. Based on the stratigraphic position, similarity in lithology, age, and sulphur isotope data of the evaporitic sequences, it can be inferred that the Neoproterozoic Indo-Pakistan Plate and the Yangtze Platform were closely related palaeogeographically during the terminal Neoproterozoic. This interpretation can improve understanding of the palaeogeographical evolution of the area during the Neoproterozoic, with particular reference to the origin of biogeochemical cycles and the diagenetic evolution of the evaporitic deposits.

Opis:
The terms of soccer scoring techniques (SSTs) used in practice and research have been remaining confusing; even dramatic, we still do not know how many SSTs available for the game. This scenario hinders not only the scientific studies on some unique SSTs but also the development of novel coaching methods for learning these SSTs. The current paper aims to bridge the gap by establishing a SST terminology system. The system is built based on goal repeatability, selected anatomical & biomechanical parameters, and analyses of 579 attractive goals from international professional tournaments. The results have revealed that there are 43 SSTs existed in current soccer practice. Some SSTs can be identified by preliminary parameters (i.e. anatomical parameters, the ball vertical position at the shot and the hit-point on the ball), but most of them need additional biomechanical examination on the movement control in frontal & transverse planes, jumping control, and trunk orientation at shots in order to identify uniquely. Further, the new SST terminology has disclosed that soccer attractiveness is linked to the diversity, ingenuity and artistry of shots. The most attractive type of scoring awaited by millions of spectators is aerial shots. Lastly, the most important contribution of the new SST terminology system is to help researchers and practitioners launch target-orientated studies that would provide a practical and convincing scientific coach-method, clear definitions, and means to reevaluate and improve SSTs in practice.

Opis:
A novel technology for the simultaneous and independent measurement of dual parameters is proposed and experimented. By using a single fiber Bragg grating half-pasted by 1C-LV epoxy under different curing conditions, the sensor structure is designed such that the reflective single-peak spectrum splits into a twin-peak spectrum, which makes the FBG spectrum form a natural spectral peak splitting bias. A measurement limitation exists in the FBG sensor packaging at room temperature, which can be solved by the high-temperature cured packaging method. To verify the validity of the theory and methodology, the experimental system is used. In the range from –1000 to +1000 με and from 35 to 75°C, the Bragg wavelength change is relative linear to the strain and temperature. The temperature and strain variations can be independently and simultaneously measured using the split peak, and the deviations of the FBG sensor are ±1°C and ±5 με, respectively. This single FBG sensor can realize dual-parameter measurement, which is valuable for narrow-space health monitoring.

Opis:
In order to study the change in performance of the Suifenhe cable-stayed bridge in China over 12 years, cable force, elevation, static and dynamic load tests were conducted in 2006 and 2018, respectively. In this paper, theoretical data, obtained through finite element model analysis, were compared with the measured load test data for changes in static and dynamic performances. A comparison between 2006 and 2018 shows that additional dead load deflection exists in the main span after 12 years of operation. And that the cable force due to dead load of the full-scale cable-stayed bridge decreases and redistributes, which have adverse effects on the safety of bridge structure after long-term operations. Therefore, on-site inspection, static and dynamic load tests are reco mmended for cable-stayed bridges over 10-years old to test their static and dynamic performance. Moreover, cable force adjustments are to be conducted whenever necessary for the cable-stayed bridge used swivel construction.

Opis:
The influence of UV radiation on the gloss, structure (SEM, FTIR), thermal (TGA, DTG) and mechanical properties of polyurethane resins and the three-layer protective coating made of them was investigated. The gloss of the resins was greater than that of the protective coating. UV radiation has been proven to reduce gloss (at 1,200 hours irradiation, 81.3° to 8.9° for resins, and 61.1° to 2.8° for coating).The tensile strength of the resins decreased during aging, and the relative elongation at break after reaching the minimum was increased (at the irradiation time of 100 h). In the case of coating, both the tensile strength and elongation decreased during aging and, after reaching the minimum they increased (at the irradiation time of 800 h), reaching the maximum (at the irradiation time of 1000 h), and then decreased.
Zbadano wpływ promieniowania UV na połysk, strukturę (SEM, FTIR), właściwości termiczne (TGA, DTG) i mechaniczne żywic poliuretanowych oraz wykonanej z nich trójwarstwowej powłoki ochronnej. Połysk żywic był większy niż powłoki ochronnej. Potwierdzono, że promieniowanie UV zmniejsza połysk (przy naświetlaniu przez 1200 godzin, w przypadku żywic z 81,3° do 8,9°, a w przypadku powłok z 61,1° do 2,8°). Wytrzymałość na rozciąganie żywic zmniejszała się w trakcie starzenia, a wydłużenie względne przy zerwaniu po osiągnięciu minimum zwiększało (przy czasie naświetlania 100 h). W przypadku powłoki zarówno wytrzymałość na rozciąganie, jak i wydłużenie zmniejszały się w trakcie starzenia i po osiągnięciu minimum zwiększały (przy czasie naświetlania 800 h), osiągając maksimum (przy czasie naświetlania 1000 h), a następnie zmniejszały.

Let D be a strong digraph. An arc subset S is a k-restricted arc cut of D if D − S has a strong component D′ with order at least k such that D\V (D′) contains a connected subdigraph with order at least k. If such a k-restricted arc cut exists in D, then D is called λk-connected. For a λk-connected digraph D, the k-restricted arc connectivity, denoted by λk(D), is the minimum cardinality over all k-restricted arc cuts of D. It is known that for many digraphs λk(D) ≤ ξk(D), where ξk(D) denotes the minimum k-degree of D. D is called λk-optimal if λk(D) = ξk(D). In this paper, we will give some sufficient conditions for digraphs and bipartite digraphs to be λ3-optimal.

Opis:
In order to effectively monitor the wear and predict the life of cylinder liner, a nonlinear degradation model with multi-source uncertainty based on Wiener process is established to evaluate the remaining useful life (RUL) of cylinder liner wear. Due to complex service performance of cylinder liner, the uncertainty of operational environment and working conditions of cylinder liner wear are considered into the model by a random function. The probability density function (PDF) formula of RUL is derived, and the maximum likelihood estimation method is adopted to estimate the unknown parameters of PDF. Considering the evaluated parameters as the initial values, the model parameters are updated adaptively, and an adaptive PDF is obtained. Furthermore, the proposed model is compared with two classical degradation models. The results show that the proposed model has a good performance for predicting the life, and the error is within 5%. The method can provide a reference for condition monitoring of cylinder liner wear.

The meso-level which reveals deformation phenomena of granular materials under the action of external loads is highly complex. At the qualitative level, the static compaction process of coal gangue samples can be roughly divided into three stages: initial compaction stage, compaction and crushing stage, and crushing (compaction) stage. It is proved that the interaction of lateral confined unidirectional compression of granular materials is mainly compression.
