Opis:: We present a precise measurement of double-polarization asymmetries in the $^{3}\vec{He} \left ( \vec{e}, {e}'d \right )$ reaction. This particular process is a uniquely sensitive probe of hadron dynamics in $^{3}He$ and the structure of the underlying electromagnetic currents. The measurements have been performed in and around quasielastic kinematics at $Q^{2}=0.25(GeV/c)^{2}$ for missing momenta up to 270 MeV/c. The asymmetries are in fair agreement with the state-of-the-art calculations in terms of their functional dependencies on $p_{m}$ and $\omega$ , but are systematically offset. Beyond the region of the quasielastic peak, the discrepancies become even more pronounced. Thus, our measurements have been able to reveal deficiencies in the most sophisticated calculations of the three-body nuclear system, and indicate that further refinement in the treatment of their two-and/or three-body dynamics is required.

Opis:: The impact of the bleed off-take cavity within aspirated blades on the aerodynamic perfor- mance of a highly loaded compressor cascade was explored. Three-dimensional Navier-Stokes simulations were conducted in rectangular compressor cascades after validation against expe- rimental results were done. Five different off-take configurations with varying suction loca- tion were numerically evaluated. The results show that the regularities of the suction flow distribution on the suction slot inlet greatly influence the benefits of boundary layer suction. The distribution style greatly depends not only on the flow condition of the blade passage, but also on the realization of the suction process and the geometry of the cavity inside the aspirated blade. The low kinetic fluid in the endwall region compared with that around the midspan is usually prone to be sucked into the suction slot. The distribution of the suc- tion mass flow along the spanwise direction would be symmetrical if the suction position is properly selected and the inside off-take cavity is well designed, even though the bleeding system has been simplified to be asymmetrical as employed in the present document.

Opis:: We propose an optical system employing a compound parabolic concentrator for near infrared spectroscope in noninvasive blood components testing. A truncated two-stage compound parabolic concentrator system is designed, which consists of a normal first-stage compound parabolic concentrator and a truncated second-stage compound parabolic concentrator. Using advanced ray tracing technique, the optical efficiencies of truncated two-stage compound parabolic concentrator system, ellipsoidal mirror system and non-optical-focusing mirror system are calculated to be 25.4%, 22.4% and 4.0%, respectively. Furthermore, the total length of truncated two-stage compound parabolic concentrator is only about 68 mm while the ellipsoidal mirror is 110 mm. It indicates that the truncated two-stage compound parabolic concentrator system enhances the ability of concentrating human diffuse transmission light, and it is a benefit to improve signal-to-noise ratio of noninvasive biochemical analysis system efficiently. Due to the advantage of small size, it tends to achieve a miniature instrument.

Opis:: The activated sludge process of the digestate liquors after chemical separation was conducted using a 10 L lab-scale sequencing batch reactor (SBR) and a 0.50 m³ pilot-scale SBR independently (with pH control). Due to the relatively high concentration of free ammonia (FA), clear inhibitory effects of the digestate liquors on the nitrifying bacteria were observed. The adaptation of the activated sludge to the toxicity was evaluated with the trends of ammonia uptake rate (AUR) and nitrate utilization rate (NUR). The lab-scale AUR values decreased from 5.3 to 2.6 g N/(kg VSS·h) over time after the addition of digestate liquors (5–10% of the reactor working volume), indicating an apparent FA inhibition on the nitrification process in the FA concentration range of 0.3–0.5 mg N/L. The pilot-scale AUR values increased from 1.8 to 3.6 g N/ (kg VSS·h) in the first two weeks and then decreased to 2.4 g N/(kg VSS·h), showing a lag of the inhibition on the nitrifying bacteria at the FA concentration ≈ 0.15 mg N/L. The lab-scale NURs increased from 2.6 to 10.4 g N/(kg VSS·h) over time, and the pilot-scale NURs increased from 1.0 to 4.0 g N/(kg VSS·h) in a similar pattern. The clear dependence of both the lab- and pilot-scale NURs on time indicated the adaptation of the heterotrophic biomass to the digestate liquors. Ethanol – used instead of fusel oil – was found to be a more efficient external carbon source for better adaptation of the activated sludge under unfavorable conditions.

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:: An investigation was made on the electromagnetic shielding behaviour and other functional properties for manufactured multifunctional elastic warp-knitted fabrics. Bamboo charcoal polyester/Crisscross-section polyester (BC-PET/CSP) blended yarns were used as the back of the warp-knitted fabric while conductive composite yarns were used as the front. The variation in the far infrared emissivity and anion density of elastic-warp knitted fabrics produced with different proportions of BC-PET content were studied in detail. Moreover the electromagnetic shielding effectiveness (EMSE) of the fabrics with different elongation was measured in this study. The experimental results showed that increased elongation almost did not significantly affect the EM shielding behaviour of fabric K1 in the elongation range of 0 - 40%. Finally to increase the EMSE of the fabric, the lamination method was used in this study. EMSE measurement results showed that two layer K1 warpknitted fabrics with 90° interval displayed a better shielding effect against the EM wave compared to that with a 0° interval.
Przeprowadzono badania właściwości ekranujących przed polem elektromagnetycznym i innych właściwości funkcyjnych wyprodukowanych wielofunkcyjnych elastycznych dzianin kolumienkowych. Zastosowano przędze kompozytowe z mieszanek zawierających drut ze stali kwasoodpornej, ciągłe włókna poliamidowe i poliestrowe oraz cięte włókna ze regenerowanej celulozy z surowca bambusowego. Badano emisyjność w dalekiej podczerwieni i gęstość anionową dzianin kolumienkowych wytworzonych przy rożnych proporcjach zastosowanych składników. Poza tym badano efektywność ochrony elektromagnetycznej dzianin przy rożnych wydłużeniach. Wyniki eksperymentów pokazują, że zwiększone wydłużenie prawie nie wpływa istotnie na właściwości ekranujące. Dla zwiększenia efektu ekranowania zastosowano metodę laminacji.

Opis:: 3,3’-Dinitro-5,5’-diamino-bi-1,2,4-triazole (DABNT) was synthesized by a facile method and its crystalline density was determined as 1.839 g·cm−3 at 293(2) K by X-ray diffraction. Its thermal decomposition kinetics and mechanism were studied by means of differential scanning calorimetry-thermogravimetry (DCS-TG), in situ thermolysis by rapid-scan Fourier transform infrared spectroscopy (RSFTIR) and simultaneous TG-IR technology. The results showed that the apparent activation energies obtained by the Kissinger, Ozawa and Starink methods were 122.9 kJ·mol−1, 123.2 kJ·mol−1 and 123.5 kJ·mol−1, respectively. The thermodynamic parameters of ΔS≠, ΔH≠ and ΔG≠ were −37.5 J·K−1·mol−1, 118.4 kJ·mol−1 and 138.7 kJ·mol−1, respectively. The decomposition reaction process of DABNT starts with the transformation from a primary amine to a secondary amine and then the loss of one nitro-group from the DABNT structure. Gaseous products, such as N2O and H2O, were detected from decomposition in the range of 50-300 °C. Density functional theory (DFT) calculations were further employed to illustrate the decomposition mechanism. The above-mentioned information on the synthesis and thermal behaviour is quite useful for the scale-up and evaluation of the thermal safety of DABNT.

Opis:: Fatigue property of FV520B-I is affected by the ultrahigh loading frequency significantly, and the ultrasonic fatigue experimental data can’t be employed directly to analyze the fatigue failure in the actual remanufacturing engineering. However few theories about the effect of loading frequency on the fatigue property of FV520B-I has ever been proposed. In this paper, both ultrasonic experiment and conventional experiment are conducted out to obtain the fatigue data. The effect of loading frequency on the fatigue data distribution is discussed firstly, its fatigue limit declines with the increase of the loading frequency. Then the fracture surface observations are captured, the fatigue property and fatigue behavior mechanism of FV520B-I is examined by analyzing the fracture surface features, crack initiation and failure observations. A new material frequency correction factor is proposed and introduced to eliminate the influence of the loading frequency on the FV520B-I fatigue property. FV520B-I empirical fatigue life conversion model and fatigue strength conversion model are established with comprehensive use of a fitting algorithm based on the combination of experimental data and classic formula. A clear understand of the effect of loading frequency on the fatigue property of FV520B-I is novel and has an important significance in guaranteeing the accuracy of the actual fatigue analysis of FV520B-I in the remanufacturing engineering.
