Background Despite the initial evidence supporting the utility of intravascular imaging to guide percutaneous coronary intervention (PCI), adoption remains low. Recent new trial data have become available. An updated study‐level meta‐analysis comparing intravascular imaging to angiography to guide PCI was performed. This study aimed to evaluate the clinical outcomes of intravascular imaging–guided PCI compared with angiography‐guided PCI. Methods and Results A random‐effects meta‐analysis was performed on the basis of the intention‐to‐treat principle. The primary outcomes were major adverse cardiac events, cardiac death, and all‐cause death. Mixed‐effects meta‐regression was performed to investigate the impact of complex PCI on the primary outcomes. A total of 16 trials with 7814 patients were included. The weighted mean follow‐up duration was 28.8 months. Intravascular imaging led to a lower risk of major adverse cardiac events (relative risk [RR], 0.67 [95% CI, 0.55–0.82]; P

As this unmanned aerial vehicle (UAV) has a planned airframe that can carry a 25 kg payload, understanding its structural capabilities, such as its compressive and tensile strengths under different situations, is essential. For the purpose of comprehending the fluid–structure interaction (FSI) of the fuselage, this study designs and analyses the lightweight materials used in the airframe of a complex Gyrodyne UAV. A computer model of a composite airframe for a Gyrodyne UAV is built to examine its durability. An essential factor in the aircraft business is minimizing unnecessary weight, and this FSI study emphasizes the importance of sandwiches and their hybrid combinations in this regard. After the material finalization, around 140 material combinations are tested using an advanced computational composite platform, in which four different lightweight material families are implemented. The fluid load (pressure) is imported into ANSYS workbench 17.2, and the structural airframe is then solved according to the boundary conditions of the application domain. Also, experimental experiments using the high-speed jet facility are run to verify computational improvements. Materials for the airframe of the Gyrodyne UAV have been narrowed down to a final list of contenders. As the work focuses on the FSI analysis, not much computational fluid dynamics (CFD) results were discussed here. Only the imported pressure from the CFD analysis was imposed on to the Gyrodyne UAV to proceed for the FSI analysis.

Sacred groves are a traditional form of community forest management and conservation linked with the beliefs, attitudes and perceptions of the communities under whose care they exist. 'law Ryngkew Lum Swer and 'law Lyngdoh / Mawphlang sacred grove are two sacred groves found in Meghalaya, India. Understanding the attitudes and perceptions of the communities that manage them would grant a better understanding of how the sacred groves are viewed and administered. To this end, a structured questionnaire was distributed at the village ofSwer, near'law Ryngkew Lum Swer and the villages of Dongiewrim and Nongrum, located adjacent to 'law Lyngdoh/Mawphlang sacred grove. A structured questionnaire was distributed and 272 were returned duly filled. Cronbach's Alpha Reliability Test for ordinal data obtained via the implementation of a 5 point Likert Scale tested above 0.7 for both sites indicating high data reliability. Most respondents were aware of the sacred grove in their vicinity, but did not to participate in religious ceremonies associated with sacred groves citing various reasons including gender and religious belief. Respondents stated that rituals have not been conducted at Mawphlang for several decades while at Swer they are still conducted. Notable percentages of respondents at both sites still believe sacred groves to be the dwelling place of spirits who would punish violators. A greater percentage at Mawphlang viewed sacred groves as a source of income and employment than at Swer. This may be because Mawphlang sacred grove is a popular commercial tourist attraction while law Ryngkew Lum Swer is not. The paper highlights the importance of sacred groves in the perceptions of local communities and their view regarding the need to conserve them. [ABSTRACT FROM AUTHOR]
