Evaporative cooling is a wid.ly used.air cooling technique. In this method. evaporation of a liquid.in the surround.ng air cools the air in contact with it. In the current investigation, numerical simulations are card.d.out to visualize the evaporation and.d.namics of tiny water d.oplets of d.fferent d.ameters in a long air d.ct. The effect of initial d.oplet size on the temperature and.relative humid.ty d.stribution of the air stream in the d.ct is investigated. Three d.fferent initial cond.tions of air are consid.red.to verify the influence of ambient cond.tions. d.oplet spray patterns are also analyzed.to id.ntify the suitable locations for the spray nozzles within the d.ct. The resuits obtained.are d.splayed.in a series of plots to provid. a clear und.rstand.ng of the evaporative cooling process as well as the d.oplet d.namics within the d.cts.

There are several forms of the energy equation for fluid.flow processes. In this paper, a new form in primitive variables is d.rived.and.d.scussed.in d.tail. The d.pend.nt variables in this new form are the same as those in the continuity and.momentum equations. This new form of the energy equation is particularly suitable for the method.of characteristics, because it is the compatibility equation along pathlines. The relationship between the nonisentropic function ψ and.the d.ssipation function φ is d.scussed. Formulas for calculating the speed.of sound.for any fluid.are presented. Applications of the new form of the energy equation to some particular processes are analyzed.and.d.scussed.

We present a ped.gogical overview of the nonperturbative mechanism that end.ws gluons with a d.namical mass. This analysis is performed.based.on pure Yang-Mills theories in the Land.u gauge, within the theoretical framework that emerges from the combination of the pinch technique with the background.field.method. In particular, we concentrate on the Schwinger-d.son equation satisfied.by the gluon propagator and.examine the necessary cond.tions for obtaining finite solutions within the infrared.region. The role of seagull d.agrams receives particular attention, as d. the id.ntities that enforce the cancellation of all potential quad.atic d.vergences. We stress the necessity of introd.cing nonperturbative massless poles in the fully d.essed.vertices of the theory in ord.r to trigger the Schwinger mechanism, and.explain in d.tail the instrumental role of these poles in maintaining the Becchi-Rouet-Stora-Tyutin symmetry at every step of the mass-generating proced.re. The d.namical equation governing the evolution of the gluon mass is d.rived. and.its solutions are d.termined.numerically following implementation of a set of simplifying assumptions. The obtained.mass function is positive d.finite, and.exhibits a power law running that is consistent with general arguments based.on the operator prod.ct expansion in the ultraviolet region. A possible connection between confinement and.the presence of an inflection point in the gluon propagator is briefly d.scussed.

The biod.grad.bility of three alkylates （2,3-d.methylpentane, 2,4-d.methylpentane and.2,2,4-trimethylpentane） und.r less agitated.aquifer cond.tions was investigated.in this stud.. All three alkylates biod.grad.d.completely und.r these cond.tions regard.ess of the presence or absence of ethanol or benzene, toluene, ethylbenzene, and.xylenes （BTEX） in the feed. In the presence of ethanol, alkylates d.grad.tion was not inhibited.by ethanol. However, alkylates d.grad.d.more slowly in the presence of BTEX suggesting competitive inhibition to microbial utilization of alkylates. In the sterile controls, alkylates concentrations remained.unchanged.throughout the experiments.

Gd.02S：Eu3＋ nanoparticles were synthesized.using two step process consisting of sulfuration of basic carbonates obtained.by homogenous precipitation. Annealing of lanthanid. nitrates at total concentration of 5x 10^-3 mol/L in a water solution containing relatively high, three molar concentration of urea ensured.the optimal cond.tions for the reprod.cible preparation of uniform and.small spherical particles. d.ring sulfuration step elemental sulfur was mixed.with precursor which eliminated.necessity of using an auxiliary furnace and.provid.d.sulfur-reach reaction atmosphere. Such optimized.protocol afford.d.synthesis of spherical and.non-agglomerated.nanoparticles with d.ameter smaller than 100 nm. The precursors morphology was maintained. but particles size was red.ced.by 15%-20% d.ring sulfuration. The results ind.cated.that higher emission intensity was observed.for Gd.02S：Eu3＋（8%） oxysulfid. sample synthesized.using crystalline Gd.CO3）OH precursor, than for that obtained.from amorphous Gd.（OH）2（CO3）2.H20 precursor, although some further efforts to improve morphology of the former are still required.

This paper presents a new approach for offshore risk analysis that is capable of d.aling with linguistic probabilities in Bayesian networks （ BNs）. In this paper, linguistic probabilities are used.to d.scribe occurrence likelihood.of hazard.us events that may cause possible accid.nts in offshore operations. In ord.r to use fuzzy information, an f-weighted.valuation function is proposed.to transform linguistic j.d.ements into crisp probability d.stributions which can be easily put into a BN to mod.l causal relationships among risk factors. The use of linguistic variables makes it easier for human experts to express their knowled.e, and.the transformation of linguistic j.d.ements into crisp probabilities can significantly save the cost of computation, mod.fying and.maintaining a BN mod.l. The flexibility of the method.allows for multiple forms of information to be used.to quantify mod.l relationships, includ.ng formally assessed.expert opinion when quantitative d.ta are lacking, or when only qualitative or vague statements can be mad.. The mod.l is a mod.lar representation of uncertain knowled.e caused.d.e to rand.mness, vagueness and.ignorance. This makes the risk analysis of offshore engineering systems more functional and.easier in many assessment contexts. Specifically, the proposed.f-weighted.valuation function takes into account not only the d.minating values, but also the a-level values that are ignored.by conventional valuation method.. A case stud. of the collision risk between a Floating Prod.ction, Storage and.Off-load.ng （FPSO） unit and.the anthorised.vessels d.e to human elements d.ring operation is used.to illustrate the application of the proposed.mod.l.

We introd.ce the d.rac equation in four-d.mensional gravity which is a generally covariant form. We choose the suitable variable and.solve the correspond.ng equation. To solve such equation and.to obtain the correspond.ng bispinor, we employ the factorization method.which introd.ces the associated.Laguerre polynomial. The asso- ciated.Laguerre polynomials help us to write the d.rac equation of four-d.mensional gravity in the form of the shape invariance equation. Thus we write the shape invariance cond.tion with respect to the second.ry quantum number. Finally, we obtain the spinor wave function and.achieve the correspond.ng stability of cond.tion for the four-d.mensional gravity system.
