Journal of High Energy Physics, Gravitation and Cosmology 2024年第3期10卷 1095-1137页

作者： rafael Cañete Mesa Independent Researcher Seville Spain

In this paper we develop and study, as the second part of one more general development, the energy transmutation equation for the material singularity, previously obtained through the symmetrisation of a wave packet, that is, we develop the correlation between the terms of this equation, which accounts for the formation of matter from a previous vibrational state, and the different possible energy species. These energetic species are ascribed, in a simplified form, to the equation E¯ω=E¯k+E¯f, which allows us, through its associated phase factor, to gain an insight into the wave character of the kinetic energy and thus to attain the basis of the matter-wave, and all sorts of related phenomenologies, including that concerning quantum entanglement. The formation of the matter was previously identified as an energetic process, analogous to the kinetic one, in which finally the inertial mass is consolidated as a mass in a different phase, now, in addition, the mass of the material singularity is identified as a volumetric density of waves of toroidal geometry created in the process of singularisation or energy transfer between species, which makes it possible to establish the real relation or correspondence between the corpuscular and photonic energy equation (E=mc2=hν), i.e. to explain through m the intimate sense of the first equivalence, which explains what νis in the second one.

背景：在髌股关节康复训练中经常进行负重的弓步动作，但这种动作下的髌股关节压力和应力状况尚不明确。方法：18名受试者在负重下做跨步和不跨步的前弓步和侧弓步动作，负重重量为可进行12次重复动作的最大负荷。将肌电学、测力平台以及运动学数据输入生物力学模型中，计算不同膝关节屈曲角度下的髌股关节压力和应力。结果：髌股关节的压力和应力随膝关节屈曲角度增加而增高，随膝关节屈衄角度减小而降低。膝关节屈曲80°-90°时，侧弓步下的髌股关节压力和应力大于前弓步；膝关节屈曲10°-50°时，跨步下的髌股关节压力和应力大于不跨步。弓步和跨步之间无明显的相互作用。膝关节屈曲0°—50°时髌股关节压力和应力小于膝关节屈曲60°～90°时的压力和应力，因此在髌股关节康复训练早期应限制膝关节屈曲在50°以内。解释：为了尽量减小髌股关节的压力和应力，应当在不跨步下进行前弓步和侧弓步练习，尤其是膝关节屈曲0°～50°时。了解不同弓步间髌股关节压力和应力的差异，可能有助于临床医生制定更加安全有效的康复训练方法。

We determined whether the inclusion of 100 g/kg dry matter of grape pomace silage (GPS) and grape pomace bran (GPB) as substitutes for other traditional fiber sources in the diet of steers (Charolais x Nellore) would improve carcass characteristics, meat quality and composition, and shelf life. Twenty-four animals (248 ± 19.32 kg of initial body weight) were fed a high concentrate diet for 121 days. Carcass characteristics were measured, and the longissimus dorsi muscle was analyzed for fatty acid (fA) profile and composition. The meat was sliced and stored in air-permeable packages for 10 days. On each sampling day (d 1, 3, 7, and 10), oxidative stability, bacterial load, lipid and protein oxidation, and staining were analyzed. The experimental diets influenced the pH of cold carcasses only. The GPS group had a higher pH than the control. The GPS and GPB groups showed improved oxidant status (i.e., lower lipid peroxidation and concentrations of reactive oxygen species were in the meat of both groups than in control). On the first day of storage, the antioxidant enzyme glutathione S-transferase activity was more significant in the meat of the GPS and GPB groups than in the control. The bacterial loads in the meat were attenuated by GPS inclusion;there were lower total coliform counts and a trend toward lower counts for enterobacteria in the control group. The diets altered the fA profile of the meat;i.e., the GPB diet allowed for a more significant amount of the n-6 omegas in the meat, while the GPS diet showed a tendency for a more significant amount of n-6 and 9 omegas. Both diets (GPS and GPB) increased the amounts of long-chain fAs. The GPS diet decreased saturated fA levels. We conclude that the dietary treatments GPS and GPB are a promising alternative to maintain meat quality standards throughout in real-world retail conditions. These treatments gave rise to an improvement in the nutritional value of the meat due to the more significant amounts of fAs that im
