The nonlinear behavior of single- and multi-story steel plate shear walls (SPSWs) strengthened with three different patterns of fiber reinforced polymer (FRP) laminates (including single-strip, multi-strip and fully FRP-strengthened models) is studied using the finite element analysis. In the research, the effects of orientation, width, thickness and type (glass or carbon) of FRP sheets as well as the system aspect ratio and height are investigated. Results show that, despite an increase in the system strength using FRP sheets, ductility of reinforced SPSWs is decreased due to the delay in the initiation of yielding in the infill wall, while their initial stiffness does not change significantly. The content/type/reinforcement pattern of FRPs does affect the nonlinear behavior characteristics and also the mode and pattern of failure. In the case of multi-strip and fully FRP-strengthened models, the use of FPR sheets almost along the direction of the infill wall tension fields can maximize the effectiveness of reinforcement. In the case of single-strip pattern, the effectiveness of reinforcement is decreased for larger aspect ratios. Moreover, a relatively simplified and approximate theoretical procedure for estimating the strength of SPSWs reinforced with different patterns of FRP laminates is presented and compared with the analytical results.

Fracture toughness of particulate composites of Al2O3/SiC, Al2O3/ZrO2 and Al2O3/ZrO2/SiC was analysed theoretically. According to the suggested particle bridging model for obtaining the R-curve height, the crack extension resistance for the long crack was linearly proportional to the residual calmping stress at the interface between the second phase and the matrix. It was also a function of the particle size and the content. It was confirmed that the rising R-curve behavior of Al2O3 containing 30 vol% SiC particles of 3${\mu}{\textrm}{m}$ was owing to the strong crack bridging by SiC particles. For Al2O3/ZrO2/SiC composites, the tensional stress from the 3${\mu}{\textrm}{m}$ SiC particles was large enough to activate the spontaneous transformation of the ZrO2. The crack extension resistance due to the particle bridging mechanism did not seem to be affected much by the coupled toughening, but its resultant toughness increase could be significantly smaller due to the dependency on the matrix toughness.

The use of low-cost substrates represents one key issue to make single cell oil production sustainable. Among low-input crops, Arundo donax L. is a perennial herbaceous rhizomatous grass containing both C5 and C6 carbohydrates. The scope of the present work was to investigate and optimize the production of lipids by the oleaginous yeast Cutaneotrichosporon curvatus from undetoxified lignocellulosic hydrolysates of steam-pretreated A. donax. The growth of C. curvatus was first optimized in synthetic media, similar in terms of sugar concentration to hydrolysates, by applying the response surface methodology (RSM) analysis. Then the bioconversion of undetoxified hydrolysates was investigated. A fed-batch process for the fermentation of A. donax hydrolysates was finally implemented in a 2-L bioreactor. Under optimized conditions, the total lipid content was 64% of the dry cell weight and the lipid yield was 63% of the theoretical. The fatty acid profile of C. curvatus triglycerides contained 27% palmitic acid, 33% oleic acid and 32% linoleic acid. These results proved the potential of lipid production from A. donax, which is particularly important for their consideration as substitutes for vegetable oils in many applications such as biodiesel or bioplastics.

The quality of experience (QoE) of video streaming is degraded by playback interruptions, which can be mitigated by the playout buffers of end users. To analyze the impact of playout buffer dynamics on the QoE of wireless adaptive hypertext transfer protocol (HTTP) progressive video, we model the playout buffer as a G/D/1 queue with an arbitrary packet arrival rate and deterministic service time. Because all video packets within a block must be available in the playout buffer before that block is decoded, playback interruption can occur even when the playout buffer is non-empty. We analyze the queue length evolution of the playout buffer using diffusion approximation. Closed-form expressions for user-perceived video quality are derived in terms of the buffering delay, playback duration, and interruption probability for an infinite buffer size, the packet loss probability and re-buffering probability for a finite buffer size. Simulation results verify our theoretical analysis and reveal that the impact of playout buffer dynamics on QoE is content dependent, which can contribute to the design of QoE-driven wireless adaptive HTTP progressive video management.

Purpose: This study aimed to explore frontline nurses' experience of patient-centered care and understand the factors affecting its implementation in hospitals. Methods: Four focus group interviews were conducted with 30 nurses in two university hospitals. The following theoretical framework of patient-centered care was used: 1) Respect for patients' values, preferences, and expressed needs, 2) Care coordination and integration, 3) Information, communication, and education, 4) Physical comfort, 5) Emotional support and alleviation of fear and anxiety, 6) Involvement of family and friends, 7) Care transition and continuity, and 8) System issues. We performed a directed content analysis. Results: The most frequent patient-centered nursing practices of the hospital nurses were "promoting physical comfort" in inpatient settings and "providing information and communicating" in outpatient settings. The factors influencing patient-centered nursing included the health professionals' mindfulness, work overload and staff shortage, and unreasonable social demands and regulations. Conclusion: A more comprehensive patient-centered nursing practice should be implemented by improving "care transition and continuity," "family/caregiver involvement," and "system building." Health professionals' mindfulness is significant, and organizational supports addressing work overload and staff shortage are needed alongside change in social awareness.

The phenomenon of money laundering through capital market instruments and various investment instruments in it is a challenge for law enforcement officials, particularly the Corruption Eradication Commission (KPK) in investigating money laundering crimes originating from corruption. This study aims to analyze comprehensively about: (1) implementation of policies on prevention and eradication of money laundering at the KPK in the context of handling money laundering on the capital market; and (2) an effective model for implementing policies to prevent and eradicate money laundering in the KPK in the context of handling money laundering on the capital market. By using a qualitative approach and Interactive Model analysis from Miles and Huberman, it was concluded that the results of the implementation of the policy of preventing and eradicating money laundering at the Corruption Eradication Commission in the context of handling money laundering crimes in the capital market had a positive impact on society, individuals and groups. The theoretical implications of the results of this study are related to the content of policy that is still relevant but for the context of implementation it needs to be refined or reconstructed by adding three elements, namely: communication, monitoring, and evaluation and security.
