But this is just misunderstanding of physics based off of the false notion that general relativity is correct in explaining the universe any more than its math contribution. \u0000Methodology: I will explain exactly what neutrinos and potons are in this paper according to the reasoning of Dynamic Gravity, the only theory of gravity that can accurately calculate gravity, dark energy, and dark matter perfectly with observation with the same equation. \u0000Findings: The most powerful form of a gravity field would be a gravnetic field created by neutrinos in motion as electrons are in electric magnetic fields. Dynamic Gravity once again rises above all other theories in explaining every single aspect of the universe and physics in a way that all other theories can only dream of. Dynamic Gravity does confidently explain almost every single observation ever made in space and on this planet. In the name of science, proceed cautiously and assume nothing is incontrovertible. \u0000Unique Contribution to Theory, Practice and Policy: Dynamic Gravity recommends that experiments take place to measure the value G for different sources of gravity other then the sole source of Lead, and assuming that all other materials are the same.","PeriodicalId":135806,"journal":{"name":"European Journal of Physical Sciences","volume":"33 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141808143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Popper’s Propensity Interpretation of Quantum Physics as a form of Modal Metaphysics","authors":"Basilis Dzelajei","doi":"10.47672/ejps.1528","DOIUrl":"https://doi.org/10.47672/ejps.1528","url":null,"abstract":"With the emergence of quantum physics in the 1920s, the major philosophical question was, do the unobservables in quantum system have ontological status or are mere instruments for scientific prediction? The Copenhagen interpretation developed an instrumentalist thesis, contending that the unobservables are tools for making predictions concerning the observables. Thus, we cannot have knowledge of the quantum particles. However, Popper attempts a realist and an objective interpretation. As such, he criticizes the Copenhagen interpretation, developing the propensity view, which accords ontological status to subatomic particles. The main thrust of our argument in this paper is that by replacing probability possibilities with propensities, Popper positions himself as a proponent of the metaphysics of modality. It is then our objective to establish the parallelism between Popper’s Propensity Interpretation and Modal Metaphysics.  To establish this contention we proceeded analytically: firstly by situating the seismic shift from macro to quantum physics, secondly by examining Popper’s critique of the Copenhagen Interpretation and thirdly by attempting a demonstration of the correlation between Popper’s propensity interpretation and modal metaphysics. The merit of this paper resides in its elucidation of the importance of metaphysics in science. It is a double challenge at the same time for antimetaphysical philosophy of science and for antiscientific metaphysics, to rethink the relationship between Metaphysics and science and invest in finding how both disciplines nurture each other. Finally, it is hoped that policy makers in Philosphy and science uses our findings to revamp the conceptualisation and practice of interdisciplinarity. \u0000 ","PeriodicalId":135806,"journal":{"name":"European Journal of Physical Sciences","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132559894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the parameter to be investigated was varied while others were fixed. The effectiveness of the immobilization protocol were assessed using four catalytic parameters – protein loading, immobilization yield, specific activity and ester yield.   Statistical analysis was performed using one way ANOVA (IBM SPSS -20.0) software while significant differences within ranges in a parameter, if any was given as p  0.05. \u0000Findings: The study revealed that the optimal values of concentration of CRL solution, immobilization time and immobilization temperature required to immobilize CRL onto SiO2-MNPs derived from oil palm leave were 5. 0 mg/mL, 16 h and 25  respectively.

High energy output gain is essential for ICF reactors and greater energy efficiency can reduce energy costs. The injection of Ion beam is one method used to achieve FI fusion reaction in ICF. A fusion of deuteron with lithium-6 isotope, DLi6 is reviewed in this work alongside the fusion of Deuterium – Tritium (DT), Deuterium – Deuterium (DD), Deuterium – Helium-3 (DHe3) and Proton – Boron-11 (PB11). \u0000Materials and Methods: In this work, it is proposed the projection of laser-driven deuteron beam in the FI scheme for ICF in the DLi6 plasma. Fusion occurs as the projected deuteron ion beam hits the lithium-6 target in the thermonuclear fusion reaction. \u0000Results: The results show that the fusion reactions of DD, DHe3 and PB11 all require high input kinetic energy (Mega-electronvolts) for the fusion process to occur because of higher Coulomb barrier and the probability of fusion increases by increasing the input energy drive with low output energy gain. DT fusion which require low input kinetic energy of about 400 KeV with high cross section and generated considerable high output energy gain of about 17.59 MeV, However this fusion reaction require large tritium inventory and tritium does not occur naturally, therefore the need for tritium breeding. When the energy of deuteron beam is projected at 200 keV to lithium-6 isotope target, although D + Li6 has a low total cross section of about 19.409 mbarn, the stopping power of the electrons would be more than ions, nuclear stopping power is considerable at very low deuterons energies, the Coulomb interaction of deuteron and lithium-6 occurs with output energy gain of about 22.373 MeV. \u0000Conclusion: The investigations indicate that fusion target energy gain efficiency is independent of lithium-6 numerical density. The highest value of energy efficiency gain occurs with lower input kinetic energy of deuteron beam of about 200 KeV to lithium-target. \u0000Recommendation: This findings contribute to the core mission of NIF in achieving fast ignition with low ignition energy input to achieve Lawson break-even or \"ignition\" point of the fusion fuel pellet, where it gives off 100% or more energy than it absorbs. However the simulation results were based on programmed model of Geant4 Hadr03.
