Opis:
The spinning triangle is a critical region in the spinning process of yarn. Its geometry influences the distribution of fibre tension in the spinning triangle and, thus, affects the properties of spun yarns. Therefore, taking appropriate measures to influence the spinning triangle geometry and thus improve the quality of yarn has attracted great interesting in recent years. During the geometry parameters, the horizontal offset of the twisting point to the symmetric axis of the nip line of the spinning triangle d has attracted more and more attention and is considered as one of the most critical factors influencing the quality of yarn. Therefore, in this paper, the effects of the horizontal offset d of the ring spinning triangle on yarn qualities is investigated. Firstly a theoretical model of the fibre tension distributions in the spinning triangle is given. Relationships between the fibre tension and horizontal offset of the spinning triangle are analysed theoretically. Secondly, as an application of the model proposed, the spinning triangles of a modified ring spinning system with a pair of offset devices which can change the horizontal offset ‘d’ continuously are studied. The distributions of fibre tension in the spinning triangle are simulated numerically, with the horizontal offset varying continuously. Furthermore the properties of spun yarns produced by the modified system are evaluated and analysed by using the simulation results.
Trójkąt przędący jest istotnym parametrem w procesie przędzenia. Jego geometria wpływa na rozkład naprężeń włókien w trójkącie przędącym, co oddziałuje na właściwości przędzy. Dlatego w ostatnich latach dużym zainteresowaniem cieszą się badania nad wpływem geometrii trójkąta przędącego w celu uzyskania możliwie najwyższej jakości. Konfiguracja geometryczna, w tym poziome przesunięcie trójkąta przędącego odgrywają coraz większą rolę w analizach procesu przędzenia obrączkowego. Autorzy przedstawili teoretyczny model rozkładów naprężeń włókien w trójkącie przędącym i przeanalizowali teoretyczne zależności pomiędzy naprężeniem włókien a ustawieniem trójkąta przędącego. Przeprowadzono symulację numeryczną i na jej podstawie wyciągnięto wnioski dotyczące jakości produkowanej przędzy.

Opis:
As a key research objective for low melting explosives and propellants, energetic salts have received worldwide attention. 3-Hydrazino-4-amino-1,2,4triazole (HATr) is an important high-nitrogen compound (73.65% N) with good stability. This paper focuses on the energetic salts which were formed between HATr and picric acid (PA) or 2,4,6-trinitroresorcinol (TNR). Single crystals of HATr·PA and HATr·TNR·H2O were grown and their crystal structures determined at low temperature. They both belong to the monoclinic system, P21/n space group. The thermal characteristics of the two target salts were investigated using DSC and TG-DTG. In addition, the non-isothermal decomposition kinetics, heats of combustion and sensitivity have also been investigated. The detonation pressures (P) and detonation velocities (D) of the salts have been calculated using the K-J equations. The results indicated that both salts have certain potential applications as gunpowder and propellant materials.

Opis:
Energetic salts of doubly-protonated 3-hydrazino-4-amino-1,2,4-triazole (2-4), and mono-protonated 3-hydrazino-4-amino-1,2,4-triazole (5-7), have been prepared in high yields from the corresponding oxygen-containing tetrazoles by (i) reaction of free acids and neutral 3-hydrazino-4-amino-1,2,4-triazole, or (ii) metathesis reactions of 3-hydrazinium-4-amino-1H-1,2,4-triazolium di-chloride with the silver salts of the corresponding oxygen-containing tetrazoles. All of these energetic salts were fully characterized by single-crystal X-ray diffraction, FT-IR and DSC measurements. All of the structures are dominated by extensive hydrogen bonds due to amino groups, hydrazino groups and oxygen atoms in the molecules. These salts exhibit good thermal stability, especially the salt 3-hydrazinium-4-amino-1H-1,2,4-triazolium 1H,1’H-5,5’-bitetrazole-1,1’-diolate (4), which exhibits a measured onset of decomposition temperature of 237 °C. Quantum chemical calculations, carried out using the Gaussian 03 suite of programs and based on the experimental densities were used to calculate the detonation pressures and velocities of all of the salts.

Opis:
Magnetic seeding depression (MSD), i.e. adding organic depressant (such as starch) and magnetic seeds and applying a low field intensity pre-magnetization for depressing target mineral in flotation, was investigated in the reverse flotation of hematite ore slimes. Flotation tests found that the iron recovery increased with the addition of magnetic seeds; the depressing ability of starch in flotation was further enhanced by the MSD. The increased adsorption density of starch on target mineral hematite and apparent size enlargement of fine minerals are two reasons for the MSD. Based on FTIR, VSM and AFM measurements it was demonstrated that the starch acted as a bridging adsorption between hematite and magnetic seeds by hydrogen bonding and chemisorption, and resultant coverage of the magnetic seeds and starch on hematite increased the magnetic susceptibility, being beneficial to the agglomeration of hematite fines by reducing the external magnetic intensity needed for agglomeration to take place. The model of the MSD was proposed.

Opis:
Investigation of the tensile and fatigue properties of cast magnesium alloys, created by the heated mold continuous casting process (HMC), was conducted. The mechanical properties of the Mg-HMC alloys were overall higher than those for the Mg alloys, made by the conventional gravity casting process (GC), and especially excellent mechanical properties were obtained for the Mg97Y2Zn1-HMC alloy. This was because of the fine-grained structure composed of the α-Mg phases with the interdendritic LPSO phase. Such mechanical properties were similar levels to those for conventional cast aluminum alloy (Al84.7Si10.5Cu2.5Fe1.3Zn1 alloys: ADC12), made by the GC process. Moreover, the tensile properties (σ and εf) and fatigue properties of the Mg97Y2Zn1-HMC alloy were about 1.5 times higher than that for the commercial Mg90Al9Zn1-GC alloy (AZ91). The high correlation rate between tensile properties and fatigue strength (endurance limit: σl) was obtained. With newly proposed etching technique, the residual stress in the Mg97Y2Zn1 alloy could be revealed, and it appeared that the high internal stress was severely accumulated in and around the long-period stacking-order phases (LPSO). This was made during the solidification process due to the different shrinkage rate between α-Mg and LPSO. In this etching technique, micro-cracks were observed on the sample surface, and amount of micro-cracks (density) could be a parameter to determine the severity of the internal stress, i.e., a large amount to micro-cracks is caused by the high internal stress.

Opis:
Although the social exchange relationships between employers and employees are increasingly important to the performance of safety management systems, the psychological effects of work attitudes on this relationship have been less studied. Using a sample of first-line operators and their supervisors from 188 facilities in Taiwan which had Occupational Health and Safety Assessment Series 18000 (OHSAS 18000) certification, the current research conducted an empirical investigation of the influence of safety climate on organizational citizenship behavior (OCB). Work attitude was used to disclose the psychological effect. Research results indicated that (a) safety climate was a significant predicator of OCB, (b) the psychological effect significantly influenced social exchange relationships, and (c) job satisfaction showed a stronger mediating influence than organizational commitment due to the frequent top management turnover. Discussions and implications are also addressed.

Opis:
Collisions and groundings account for more than 80% among all types of maritime accidents, and risk assessment is an essential step in the formal safety assessment. This paper proposes a method based on fuzzy fault tree analysis and Noisy-OR gate Bayesian network for navigational risk assessment. First, a fault tree model was established with historical data, and the probability of basic events is calculated using fuzzy sets. Then, the Noisy-OR gate is utilized to determine the conditional probability of related nodes and obtain the probability distribution of the consequences in the Bayesian network. Finally, this proposed method is applied to Qinzhou Port. From sensitivity analysis, several predominant influencing factors are identified, including navigational area, ship type and time of the day. The results indicate that the consequence is sensitive to the position where the accidents occurred. Consequently, this paper provides a practical and reasonable method for risk assessment for navigational accidents.

Opis:
A multi-ship collision avoidance decision-making and path planning formulation is studied in a distributed way. This paper proposes a complete set of solutions for multi-ship collision avoidance in intelligent navigation, by using a top-to-bottom organization to structure the system. The system is designed with two layers: the collision avoidance decision-making and the path planning. Under the general requirements of the International Regulations for Preventing Collisions at Sea (COLREGs), the performance of distributed path planning decision-making for anti-collision is analyzed for both give-way and stand-on ships situations, including the emergency actions taken by the stand-on ship in case of the give-way ship’s fault of collision avoidance measures. The Artificial Potential Field method(APF) is used for the path planning in details. The developed APF method combined with the model of ship domain takes the target ships’ speed and course in-to account, so that it can judge the moving characteristics of obstacles more accurately. Simulation results indicate that the system proposed can work effectiveness.

Opis:
Energetic salts as a unique class of energetic materials have recently been investigated widely, since they possess advantages over their atomically similar nonionic analogues – they tend to exhibit lower vapor pressures, higher densities and better thermal stabilities. Furthermore, these salts are readily improved upon by the appropriate combination of different cations and anions. Over the last twenty years, our group has continued to synthesize and study novel ionic energetic materials. Here, we have summarized all of the series of nitrogen-rich energetic salts. This review gives an overview of the various studies dealing with synthetic aspects and some of the physicochemical properties of ionic compounds that are based on ammonia, guanidine, semicarbazide, carbohydrazide, tetrazine, tetrazole, triazole and imidazole. In addition, their potential applications in the fields of explosives and propellants are discussed. We hope these investigations will be helpful in providing a wider insight for future research in the area of energetic salts.

Opis:
Increasing concentrations of aluminum phosphide (AlP) in waste fumigants and residues pose a serious threat to human health. This study focused on the effectiveness of the widely used simple immersion treatment for waste fumigants from shipments, which usually have a higher concentration of residual AlP. A field survey of an operational process was conducted followed by a quantitative analysis of the immersion treatment's hydrolytic effect on AlP. Further investigation on the safety of waste fumigants after the immersion treatment was conducted. It was found that the AlP concentration in the waste fumigant varied significantly with the sampling date, ranging from 12.93 +/- 0.67 wt. % to 29.50 +/- 1.18 wt. %. Simple immersion treatment could reduce the concentration of residual AlP in waste fumigants but the hydrolytic effect varied largely ranging from 19.5% to 31.9%. The concentration of residual AlP remained high (9.1-20.1 wt. %) after the immersion treatment. About 3.2-15.2 wt. % of AlP remained in the samples, following an additional 40 days of natural air-drying when phosphine gas release was not detected. The study indicates that conventional simple immersion treatment cannot ensure the complete hydrolysis of AlP from waste fumigants of shipments.

Comparison of flotation performance between the flotation column and mechanical flotation was carried out to promote the grade and economic value of the graphite ore (15.40% ash content). The ash content of the concentrate of the mechanical flotation was 10.77% at the yield of 79.34%. In contrast, the yield of the concentrate of the column flotation was increased to 88.93% with 10.55% ash content. Comparative study of the Fuerstenau upgrading curves indicated that the column flotation was more efficient for cleaning the graphite ore in the presence of the centrifugal force field, nanobubbles (generated by hydrodynamic cavitation), and the thicker froth layer in comparison with the mechanical flotation.

Opis:
Zeolite can effectively regulate the nutrient status in the root zone of crops, thereby increasing nitrogen utilization. However, there has been relatively little research conducted concerning a possible reduction in the frequency of nitrogen application due to the sustained-release properties of zeolite. In this study, 157.5 kg ha-1 nitrogen in the form of urea fertilizer was applied at the same rate, either as a one-time application or as a 3-way split application with and without 10 t ha-1 zeolite. The effects on rice yield, nitrogen uptake, root morphology and soil properties were evaluated in 2014 and 2015. Results showed that zeolite could enhance the biomass, leaf area index and nitrogen uptake. A higher rice grain yield and nitrogen uptake following soil treatment with zeolite could be attributed to a higher soil cation exchange capacity as well as nitrogen and potassium availability in the soil especially during the vegetative period of the rice plant. The addition of nitrogen to the soil as a one-time application or 3-way split application with 10 t ha-1 zeolite significantly increased rice grain yield by 8.5 or 10.7% compared with nitrogen as a one-time application without zeolite. Zeolite addition greatly improved the development of root morphology and activity compared with treatments without zeolite, which contributed to additional plant growth. The addition of nitrogen to the soil with 10 t ha-1 zeolite as a one-time application that can significantly increase nutrient retention is recommended to improve rice grain yield and decrease nitrogen application frequencies in order to lower both labour forces and energy requirements.

A compact fiber-optic accelerometer based on a modal interferometer, which is fabricated by misaligned splicing of a short section of a thin-core fiber between two sections of a standard single-mode fiber, is demonstrated experimentally. 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.
