Is MOND discarded? 


Best insight from top research papers

No, MOND (Modified Newtonian Dynamics) is not discarded. Recent studies have shown that MOND can account for various phenomena such as the baryonic Tully-Fisher relation, the mass discrepancy-acceleration relation, and the acceleration observed in the "bullet cluster" galaxies . While the gravitational-wave event GW170817 and the corresponding gamma-ray burst have ruled out certain modified gravity theories, they do not falsify MOND itself . Additionally, modified inertia (MI) formulations of MOND have been explored, which can differ from modified-gravity (MG) theories in predicting phenomena such as the external-field effect . Furthermore, observations of dwarf spheroidals have shown compelling agreement with the predictions of MOND, suggesting that dark matter may not be necessary .

The paper does not explicitly state whether MOND (Modified Newtonian Dynamics) is discarded or not. The paper discusses the various aspects and predictions of MOND and its modified inertia formulations, but does not provide a conclusion on its validity or rejection.

The paper concludes that the MOND hypothesis is unnecessary, as the HLSS model and a dark matter-based analysis can account for the observed phenomena.
The paper does not discard MOND (Modified Newtonian Dynamics) per se, but it severely constrains relativistic extensions of MOND that rely on different Shapiro delays for electromagnetic and gravitational radiation.

Discuss ways of dispose museum collection ?5 answersDisposing of museum collections is a crucial aspect of collection management. Museums face challenges due to overstocked collections resulting from decades of liberal acquisition practices. To address this, disposal should be viewed as a necessary tool in collections management, requiring clear consultation with the public. However, there is a professional reticence towards disposal, with museums continuing to collect at a significant rate without utilizing disposal effectively. It is essential for museums to establish a coherent intellectual framework to justify disposals beyond pragmatic reasons like saving costs or space. By incorporating disposal as a strategic element in collection management, museums can ensure sustainability and reduce the burden on future generations.
How much blood is typically discarded after a blood draw?5 answersOn average, the amount of blood discarded after a blood draw varies depending on the study and the specific components being considered. Studies have reported discard rates ranging from 1.76% to 61.11% for different blood components. Reasons for discarding blood include undiagnosed sterility, quality control issues, underweight units, hemolysis, expiry, and transfusion-transmitted infections. Platelets are often the most commonly discarded component due to their short shelf life and unpredictable demand. Implementing strategies like self-audits, staff training, strict donor selection criteria, and proper storage can help minimize blood wastage and improve utilization rates. Additionally, reducing the volume of blood discarded during sampling procedures from 5 mL to 3 mL has been suggested to limit iatrogenic blood loss.
What is the importance if the research is gone?4 answersResearch is important for various reasons. It provides foundational knowledge about a problem and suggests policies and strategies for addressing it. Long-term research is critical for understanding forest dynamics and informing forest management and policy. Market research is a critical function in the tourism and hospitality sector, contributing to an organization's success on a day-to-day basis. Ignoring the importance of market research in product design can lead to a lack of direction and understanding of consumer behavior, hindering market expansion. When research projects collapse, valuable insights and knowledge are lost, and researchers and participants are affected. In the case of firearm-related public health and safety problems, the lack of research and data collection hinders efforts to reduce gun violence. Overall, research plays a crucial role in generating knowledge, informing decision-making, and addressing various societal challenges.
How can we help abandoned people?5 answersTo help abandoned people, three promising models have been identified: alternative middle and high schools for those at risk of dropping out, programs aimed at helping older students earn a GED, and whole-school restructuring efforts aimed at dropout prevention. These models have been found effective in preventing dropouts and providing educational opportunities for those who have been abandoned or are at risk of being abandoned. Additionally, it is important to provide support and resources for mental health and well-being, as abandonment can have significant emotional and psychological impacts. Creating safe and supportive environments, offering counseling services, and connecting individuals with community resources can help address the needs of abandoned people and assist them in rebuilding their lives. By implementing these strategies, we can work towards providing abandoned individuals with the necessary support and opportunities for a better future.
