Polypropylene fibre (PPF) is a kind of polymer material with light weight, high strength, and corrosion resistance. The crack resistance concrete can be improved by adding PPFs. PPF optimize the pore size distribution concrete. As result, durability significantly enhanced since block penetration water or harmful ions in This paper summarizes influence polypropylene on concrete, including drying shrinkage, creep, absorption, permeability resistance, chloride ion sulfate freeze‐thaw cycle...
Simple strategies for decarboxylative functionalizations of electron-deficient benzoic acids via using Cu(I) as promoter and electron-rich ones by employing Pd(II) catalyst under aerobic conditions have been established, which lead to smooth synthesis aryl halides (−I, Br, Cl) through the functionalization with readily available halogen sources CuX (X = I, Cl), easy preparation benzonitriles from cyanation carboxylic nontoxic low-cost K4Fe(CN)6 an oxygen atmosphere first time.
The rapid expansion of large-scale text-to-image diffusion models has raised growing concerns regarding their potential misuse in creating harmful or misleading content. In this paper, we introduce MACE, a finetuning framework for the task mass concept erasure. This aims to prevent from generating images that embody unwanted concepts when prompted. Existing erasure methods are typically restricted handling fewer than five simultaneously and struggle find balance between erasing synonyms...
Anthrax is an acute infectious disease with high mortality caused by bacillus anthracis, which can severely harm human healthy. 2,6-pyridinedicarboxylic acid (DPA) the main component and a major biomarker of anthracis. Therefore, it essential to develop sensitive selective sensor for DPA detection. In this study, luminescent lanthanide nanoparticles, poly(PTEu)-PAA, were successfully synthesized introducing Europium(III)-based complex N-(4-(1,2,2-triphenylvinyl)phenyl)acrylamide (TPENA)...
Abstract Chiral homoallylic alcohols can be prepared from aldehydes upon reaction with two optically pure allylboronatetartramides. The enantiomeric excess is 10–15 % higher for the allylation of benzaldehyde when using N , ' ‐dibenzyl‐tartramide auxiliary 5b than ‐diphenyl‐tartramide ( 5a ). 2‐Allyl‐ ‐dibenzyl‐1,3,2‐dioxaborolane‐4,5‐dicarbamide 2b ) affords 90–99 ee some representative aldehydes. derivatised chiral auxiliaries recovered by simple recrystallization, in 85 yield, without any...
A cross section of the rod is taken as object investigation. The freedom in free or constraint case analyzed and definition virtual displacement given, which can be expressed by a variational operation. Assuming partial differential operations has commutativity, based on hypothesis about surface subjected to rod, discussed equations satisfied displacements are given. Combining D'Alembert principle work, D'Alembert-Lagrange established. When constitutive equation material linear, transformed...
The extended Schrödinger equation for the Kirchhoff elastic rod with noncircular cross section is derived using concept of complex rigidity. As a mathematical model supercoiled DNA, circular special case in this paper. In twistless when principal axes are coincident Frenet coordinates centreline, transformed to Duffing equation. equilibrium and stability discussed bifurcation phenomenon presented.
The problem on stability of equilibrium a thin elastic rod in view dynamics is discussed this paper. dynamical equations the established, and definitions Lyapunov for discrete system with arc-coordinate s time t as double arguments are proposed. As an example, straight noncircular cross-section intrinsic twisting analyzed by use first approximation method. It was proved that stable dynamically when conditions satisfied within scope statics.
Nonlinear mechanics of thin elastic rod, as a model DNA, aroused extensive interest joint research subject and molecular biology. The study the equilibrium rod constrained on surface found an important application in industry, especially In present paper constraint equations forces are analyzed, differential/algebraic established with arc-coordinate central line independent variable. special case when is cylinder dimensionless differential contain only one physical parameter, ratio bending...
The special solutions of the Kirchhoff equations, which are those rela tive to fixed coordinate system, principal system a cross section rod, and Frenet central line respect ively, derived in this paper. Lyapunov stability these is disc us sed by use theory on first-approximation stability, at same time area parameter's plane given.
The optimal control laws of 4WS during single lane-change are studied using the driver model preview follower method based on a certain vehicle model. actual models considered as uncertain systems. cornering stiffness front and rear wheels outer disturbance vary over limited range. An adaptative model-following variable structure is used for controlling steering vehicle, so that characteristics an can follow reference Simulation results have demonstrated system overcome drawbacks parameter...
