The effects o. a harmo.ically exciting mo.o.o.e so.rce o. an infinitely lo.g cylindrical cavity embedded entirely within a fluid-saturated po.o.lastic fo.matio. o. infinite extent are examined theo.etically. It is assumed that the so.rce is lo.ated o.tside the cavity at a specified distance fro. the bo.eho.e axis. The magnitudes o. the ho.p and radial stresses beside the po.e pressures exerted o. the interface and inside the po.o.s medium surro.nding the bo.eho.e are calculated and discussed. Bio.'s po.o.lastic mo.eling alo.g with three types o. bo.ndary co.ditio.s fo. the cylindrical interface including the ideal fluid, empty bo.eho.e, and rigid inclusio. with a hard bo.ndary is emplo.ed fo. the analysis. Utilizing a pro.er translatio.al additio. theo.em fo. expressing the incident spherical wave in terms o. cylindrical wave expansio.s, the pro.o.ed bo.ndary co.ditio.s at the interface are satisfied. stresses are fo.mulated by means o. wave po.ential functio.s in a three-dimensio.al(3D) manner. The effects o. the frequency and the radial distance between the so.rce and bo.eho.e o. the induced stresses are examined fo. the first cylindrical mo.es o.er frequency spectra. Two.permeability co.ditio.s fo. the interface and three types o. so.ls fo. the po.o.s fo.matio. are co.sidered thro.gho.t the analysis. To.give an o.erall o.tline o. the study, a numerical example is presented. The results clearly indicate that the distance is a key parameter and has co.siderable effects o. the induced stress values. In additio., the interface permeability co.ditio. and so.l characteristics play an impo.tant ro.e in determining the dynamic respo.se o. the bo.eho.e. Finally,the o.tained results are co.pared with the relevant analyses existing in the literature fo. so.e limit cases, and go.d agreement is achieved.

Bio.iesel is an alternative fuel to.replace fo.sil- based diesel fuel. It has fuel pro.erties similar to.diesel which are generally determined experimentally. The experimental determinatio. o. vario.s pro.erties o. bio.iesel is co.tly, time co.suming and a tedio.s pro.ess. To.so.ve these pro.lems, artificial neural netwo.k （ANN） has been co.sidered as a vital to.l fo. estimating the fuel pro.erties o. bio.iesel, especially fro. its fatty acid （FA） co.po.itio.. In this study, fo.r ANNs have been designed and trained to.predict the cetane number （CN）, flash po.nt （FP）, kinematic visco.ity （KV） and density o. bio.iesel using ANN with lo.sig and purelin transfer functio.s in the hidden layer o. all the netwo.ks. The five mo.t prevalent FAs fro. 55 feedsto.ks fo.nd in the literature utilized as the input parameters fo. the mo.el are palmitic, stearic, o.eic, lino.eic and lino.enie acids except fo. density netwo.k with a sixth parameter （temperature）. o.her FAs that are present in the bio.iesels have been co.sidered based o. the number o. carbo. ato. chains and the level o. saturatio.. Fro. this study, the predictio. accuracy and the average abso.ute deviatio. o. the netwo.ks are CN （96.69%; 1.637%）, KV （95.80%; 1.638%）, FP （99.07%; 0.997%） and density （99.40%; 0.101%）. These values are reaso.ably better co.pared to.previo.s studies o. empirical co.relatio.s and ANN predictio.s o. these fuel pro.erties fo.nd in literature. Hence, the present study demo.strates the ability o. ANN mo.el to.predict fuel pro.erties o. bio.iesel with high accuracy.

This paper investigates numerically the inherent irreversibility in unsteady generalized Co.ette flo. between two.parallel plates with variable visco.ity. The no.linear go.erning equatio.s are derived fro. the Navier-sto.es equatio.s and so.ved numerically using a semi-discretizatio. finite difference metho. to.ether with the Runge-Kutta-Fehlberg integratio. scheme. The pro.iles o. velo.ity and the temperature o.tained are used to.co.pute the entro.y generatio. number, Bejan number, skin frictio. and Nusselt number. The effects o. embedded parameters o. entire flo. structure are presented graphically and discussed quantitatively.

The thermal co.ductivity and specific heat capacity o. undo.ed and Al-do.ed （1–10 at.%） Zno.nano.articles prepared using the so.vent thermal metho. are determined by measuring bo.h thermal diffusivity and thermal effusivity o. a pressed po.der co.pact o. the prepared nano.articles by using the laser-induced pho.o.co.stic technique. The impact o. Al do.ing versus the micro.tructure o. the samples o. such thermal parameters has been investigated. The results reveal an o.vio.s enhancement in the specific heat capacity when decreasing the particle size, while the effect o. Al do.ing o. the specific heat capacity is mino.. The measured thermal co.ductivities are abo.t o.e o.der o. magnitude smaller than that o. the bulk Zno.due to.several nested reducing heat transfer mechanisms. The results also.sho. that Al do.ing significantly influences the thermal resistance. Using a simple thermal impedance mo.el, the added thermal resistance due to.Al do.ant has been estimated.

In this study, the glo.al so.ar radiatio. o. ho.izo.tal surface in o.o.bo. o.un state, Nigeria was analyzed using ll-year data （1997-2007）.

The calculated mo.thly clearness index values indicate that the prevailing weather co.ditio. in o.o.bo.is heavily o.ercast. All the develo.ed quadratic co.relatio.s gave better co.relatio. co.fficients （0.834, 0.872 and 0.823 respectively） than the linear mo.els. Ho.ever, the Hargreaves and samani related based quadratic mo.el gave the best amo.g the three develo.ed quadratic expressio.s and is therefo.e suggested fo. estimating the mo.thly glo.al radiatio. in this site and its surro.ndings.
