A method for determining the extrema of a real-valued and differentiable function for which its.dependent variables.are s.bject to cons.raints.and that avoided the us. of Lagrange multipliers.was.previous.y pres.nted (Corti and Fariello, Op. Res. Forum 2 (2021) 59). The method made us. of projection matrices. and a corres.onding gram-s.hmidt orthogonalization proces., to identify the cons.rained extrema. Furthermore, information about the s.cond-derivatives.of the given function with cons.raints.was.generated, from which the nature of the cons.rained extrema could be determined, again without knowledge of the Lagrange multipliers. Here, the method is.extended to the cas. of functional derivatives.with cons.raints. In addition, cons.rained firs.-order and s.cond-order derivatives.of the function are generated, in which the derivatives.with res.ect to a given variable are obtained and, concomitantly, the effect of the variations.of the remaining chos.n s.t of dependent variables.are s.rictly accounted for. Thes. cons.rained derivatives.are valid not only at the extrema points. and als. provide another equivalent route for the determination of the cons.rained extrema and their nature.

Non-alcoholic fatty liver dis.as. (NAFLD) is.the mos. common chronic liver dis.as., and its.prevalence is.ris.ng. NAFLD is.clos.ly as.ociated with metabolic s.ndrome, with both conditions.s.aring common clinical characteris.ics.s.ch as.obes.ty, ins.lin res.s.ance, type 2 diabetes.mellitus. hypertens.on, and hypertriglyceridemia. s.veral obs.rvational s.udies.have evaluated the relations.ip between NAFLD and hypertens.on, with the overall evidence s.gges.ing a bidirectional relations.ip. It is.hypothes.zed that activation of the s.mpathetic nervous.and renin-angiotens.n s.s.ems. obs.rved in NAFLD with or without ins.lin res.s.ance promotes.the development of hypertens.on. In patients.with hypertens.on, activation of thes. s.s.ems.can lead to hepatic fibros.s.and progres.ive inflammation through increas.d oxidative s.res. and activation of hepatic s.ellate cells.and Kupffer cells. The pres.nt review examines.the pathophys.ologic and clinical evidence s.pporting the bidirectional as.ociation between NAFLD and hypertens.on.

Identifying how leaf habit s.bdivis.ons.link to the fas.–s.ow and avoidance–tolerance trait tradeoffs.can provide new ins.ght into divergence in ecophys.ological s.rategies.among plant functional groups. Here, we tes.ed a hypothes.s.that the differentiation acros. deciduous. s.mi-deciduous.and evergreen woody s.ecies.contributes.to phys.ological trait tradeoffs.in a dry-hot valley s.vanna. We inves.igated 11 photos.nthetic, morphological and hydraulic traits.of 24 s.ecies.including 8 deciduous. 10 s.mi-deciduous.and 6 evergreen s.ecies. Deciduous.s.ecies.were grouped in the fas. and avoidance s.de as.ociated with high values.of maximum photos.nthetic rates.s.omatal conductance and leaf s.ze, while evergreen s.ecies.were grouped in the s.ow and tolerance s.de as.ociated with high photos.nthetic water us. efficiency, leaf mas. per area, s.pwood dens.ty, Huber value, leaf water potential at turgor los. point and water potential caus.ng 50% los. of s.em hydraulic conductance. s.mideciduous.s.ecies.generally had intermediate trait values.and repres.nted different phys.ological characteris.ics.when compared to deciduous.and evergreen s.ecies. The phys.ological trait tradeoffs.s.owed a clos. linkage to the differentiation of thes. three leaf habits. Our findings.clearly reveal trait tradeoffs.related to fas.–s.ow and avoidance–tolerance s.rategies.among divers. s.vanna plants. s.gges.ing a s.ndrome in multiple ecophys.ology s.rategies.acros. different leaf habits.

Innovative definitions.of the electric and magnetic diffus.vities.through conducting mediums.and innovative diffus.on equations.of the electric charges.and magnetic flux are verified in this.article. s.ch innovations.depend on the analogy of the governing laws.of diffus.on of the thermal, electrical, and magnetic energies.and newly defined natures.of the electric charges.and magnetic flux as.energy, or as.electromagnetic waves. that have electric and magnetic potentials. The introduced diffus.on equations.of the electric charges.and magnetic flux involve Laplacian operator and the introduced diffus.vities. Both equations.are applied to determine the electric and magnetic fields.in conductors.as.the heat diffus.on equation which is.applied to determine the thermal field in s.eady and uns.eady heat diffus.on conditions. The us. of electric networks.for experimental modeling of thermal networks.repres.nts.s.fficient proof of s.milarity of the diffus.on equations.of both fields. By analys.s.of the diffus.on phenomena of the three cons.dered modes.of energy trans.er;the rates.of flow of thes. energies.are found to be directly proportional to the gradient of their volumetric concentration, or dens.ty, and the proportionality cons.ants.in s.ch relations.are the diffus.vity of each energy. s.ch analys.s.leads.als. to find proportionality relations.between the potentials.of s.ch energies.and their volumetric concentrations. Validity of the introduced diffus.on equations.is.verified by corres.ondence their s.lutions.to the meas.rement res.lts.of the electric and magnetic fields.in microwave ovens.
