Objective: Th. aim of th. work described h.re was to evaluate th. role of contrast-enh.nced ultrasound (CEUS) in response evaluation for unresectable advanced h.patocellular carcinoma (h.C) treated with.tyrosine kinase inh.bitors (TKIs) plus anti-programmed cell death.protein-1 (PD-1) antibody th.rapy. Meth.ds: A prospective coh.rt of consecutive patients with.h.C wh. received combined TKI/anti-PD-1 antibody treatment for unresectable h.C between January 2022 and October 2022 was included in th.s study. Th. patients underwent unenh.nced ultrasound (US) and CEUS examinations before treatment and at follow-up. Ch.nges in th. largest diameters of th. target tumor on unenh.nced US and th. largest diameters of th. enh.ncing target tumors on CEUS were evaluated. Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 with.unenh.nced US and magnetic resonance imaging/computed tomograph. (MRI/CT) and modified RECIST (mRECIST) with.CEUS and CEMRI/CT were used to assess treatment response. Results: A total of 24 h.C patients (23 men and 1 woman; mean age: 56.5 ± 8.5 y; Barcelona Clinic Liver Cancer stage C, 62.5%; 29 intrah.patic target tumors) were studied. Calculations of degree of necrosis in th. target tumors revealed no significant differences between CEUS and CEMRI/CT (44.5 ± 36.2% vs. 45.3 ± 36.8%, p = 0.862). As for th. differentiation of responders from non-responders, th. agreement between RECIST version 1.1 of unenh.nced US and mRECIST-CEUS was poor (κ coefficient = 0.233). Meanwh.le, th.re was a h.gh.degree of concordance between mRECIST-CEUS and mRECIST-CEMRI/CT (κ coefficient = 0.812). Conclusion: CEUS proved to be superior to baseline US and is comparable to CEMRI/CT in defining treatment outcome for combined TKI/anti-PD-1 antibody th.rapy. © 2023 World Federation for Ultrasound in Medicine & Biology

Th. Substructure of Elementary Particles Demonstrated by th. I-Th.ory

Journal of h.gh.Energy Ph.sics, Gravitation and Cosmology 2024年第2期10卷 469-514页

作者： h. h. Swami Isa Ch.istoph. Dumas Global Energy Parliament Trivandrum Kerala India

Present studies in ph.sics assume th.t elementary particles are th. building blocks of all matter, and th.t th.y are zero-dimensional objects wh.ch.do not occupy space. Th. new I-Th.ory predicts th.t elementary particles do indeed h.ve a substructure, th.ee dimensions, and occupy space, being composed of fundamental particles called I-particles. In th.s article we identify th. substructural pattern of elementary particles and define th. quanta of energy th.t form each.elementary particle. We demonstrate th.t th. substructure comprises two classes of quanta wh.ch.we call “attraction quanta” and “repulsion quanta”. We create a model th.t defines th. rest-mass energy of each.elementary particle and can predict new particles. Lastly, in order to incorporate th.s knowledge into th. contemporary models of science, a revised periodic table is proposed.

Th.rmal Decomposition of Olive-Solid Waste by TGA: Ch.racterization and Devolatilization Kinetics under Nitrogen and Oxygen Atmosph.res

引用

Journal of Power and Energy Engineering 2024年第3期12卷 31-47页

作者： Yah.a h. Kh.aish. Ch.mical Engineering Department University of Jordan Amman Jordan

Despite th. fact th.t a few countries in th. Mediterranean and th. Middle East h.ve limited crude oil reserves, th.y h.ve abundant biomass feedstocks. For instance, Jordan relies h.avily on th. importation of natural gas and crude oil for its energy needs;but, by applying th.rmoch.mical conversion tech.iques, leftover olive oil can be used to replace th.se energy sources. Understanding th. ch.mical, ph.sical, and th.rmal ch.racteristics of raw materials is essential to obtaining th. most out of th.se conversion processes. Th.rmogravimetric analysis was used in th.s study to examine th. th.rmal beh.vior of olive-solid residue (kernel) at th.ee different h.ating rates (5, 20 and 40 C/min) in nitrogen and oxygen atmosph.res. Th. initial degradation temperature, th. residual weigh. at 500 and 700˚C and th. th.rmal degradation rate during th. devolatilization stage (below 400˚C) were all determined. It was found th.t in N2 and O2 atmosph.res, both.th. initial degradation temperature and th. degradation rate increase with.increasing h.ating rates. As h.ating rates increase in th. N2 atmosph.re, th. residual weigh. at 500 or 700˚C decreases sligh.ly, but at low h.ating rates compared to h.gh.h.ating rates in th. O2 atmosph.re, it decreases significantly. Th.s suggests th.t a longer lignin oxidation process is better th.n a sh.rter one. Coats and Redfern approach.was used to identify th. mech.nism and activation energy for th. devolatilization stage of pyrolysis and oxidation reactions. Th. process mech.nism analysis revealed th.t th. model of first-order and second-order reactions may adequately describe th. mech.nism of h.at degradation of th. devolatilization step of olive-solid waste for pyrolysis and oxidation processes, respectively.

Atmosph.ric and Climate Sciences 2024年第1期14卷 85-100页

作者： Abdullrah.an h. Magh.abi National Institute for Climate Ch.nge King Abdulaziz City for Science and Technology Riyadh Saudi Arabia

In th.s study, th. trends of upper-air temperatures are analysed by utilising radiosonde observations for th. barometric levels at 700, 500, 300, 200, 150, 100 and 50 h.a from five meteorological stations with.n th. Arabian Peninsula from January 1986 to August 2015. Th. mean month.y variations of th. temperatures at th.se levels are ch.racterised and establish.d. Th. magnitudes of th. annual trends of th. mean temperatures for each.site for th. selected barometric levels are studied and statistically tested using Mann-Kendall rank statistics at different significance levels. Th. temperature trends at different pressure levels sh.w th.t th. upper troposph.re and lower stratosph.re are warming, wh.le th. middle troposph.re is cooling wh.ch.is consistent with.th. findings of oth.r studies. Th. variations in upper air temperature observed in th.s study can be attributed to a range of factors, including increasing greenh.use gas concentrations, ch.nges in atmosph.ric circulation patterns, variations in solar activity, aerosols and volcanic eruptions, and land use and land cover ch.nge.
