What is the best molecules formation for shock nullification?5 answersThe best molecules for shock nullification have not been explicitly mentioned in the provided abstracts. However, some papers discuss the formation of molecules and particles in shock systems. Herzler et al. studied the formation of TiN molecules and particles in TiCl4/NH3/H2 systems using laser absorption spectroscopy. Tan et al. calculated the resonance energies of various explosives, indicating that lower resonance energy corresponds to higher shock sensitivity. These studies provide insights into the behavior of molecules under shock conditions, but do not specifically address the best molecules for shock nullification. Further research is needed to determine the most effective molecules for this purpose.
What is the null hypothesis?4 answersThe null hypothesis is a statement that asserts that there is no relationship between two variables or no difference between two groups. It is often used in statistical analysis to test the validity of research hypotheses in various fields, including molecular genetics and biology. The null hypothesis is typically compared to an alternative hypothesis, which suggests the presence of an effect or difference. In the testing process, if the observed results or p-value indicate that the null hypothesis is unlikely true, it is rejected in favor of the alternative hypothesis. The null hypothesis is an important concept in scientific research as it helps researchers draw valid conclusions from their studies.
What is nothing?5 answersNothing is a sociologically neglected terrain that encompasses non-identification, non-participation, and non-presence. It is created and managed through meaningful social interaction, and is accomplished through active commission or passive omission. Four dimensions of negative social space - non-identity, inactivity, absence, and silence - contribute to the productive nature of nothing, as other symbolic objects are generated through the apprehension of phantoms, imaginaries, replacements, and alternatives. This sociological analysis reveals the significance of nothing in shaping social processes. Additionally, nothing is the formless flesh that surrounds every thing, serving as a ground or horizon that allows for connection and presence. It is the presence of an absence, the divine or spiritual element that enables the existence of things. This understanding of nothing challenges the fleshless interaction model and emphasizes the constitutive ground in between.
Why less than 0.05 reject the null hypothesis?3 answersThe significance level of 0.05 is commonly used to reject the null hypothesis in statistical hypothesis testing. However, there is controversy surrounding this practice. The traditional null hypothesis significance testing (NHST) was never intended for clinical significance to be inferred from statistical significance. The American Statistical Association has stated that p-values do not provide a good measure of evidence for a hypothesis and recommend stating the exact p-value along with effect size and confidence intervals. The prevalence of true effects is not generally known, and the false discovery rate can be high, especially when using p-values close to 0.05. Lowering the alpha level to 0.005 has been proposed as a way to combat the replication crisis in psychology, as findings with p-values close to 0.05 represent insufficient empirical evidence. In summary, the use of p < 0.05 to reject the null hypothesis is based on historical convention, but there are concerns about its validity and the high false discovery rate associated with it.
Why does nulliparity increase risk of ovarian cancer?2 answersNulliparity increases the risk of ovarian cancer. Women who have never given birth have a higher likelihood of developing ovarian malignancy compared to women who have experienced one or more deliveries. The risk of ovarian cancer decreases with each childbirth, indicating a dose-response relationship. The exact reason for the increased risk among nulliparous women is not fully understood. It is unclear whether the higher risk is due to the higher proportion of nulliparous women among infertile women or if it is related to some form of ovarian pathology that contributes to both infertility and increased ovarian cancer risk. Further research is needed to better understand the relationship between nulliparity and ovarian cancer risk.
