a.dela.ed cha.ing model is proposed to simula.e the cha.e beha.ior in the queue, where ea.h member rega.ds the closest one a.ea. a. the ta.get, a.d the lea.er is a.tra.ted to a.ta.get point with slight fluctua.ion. When the initia. dista.ces between neighbors possess a. identica. low va.ue, the fluctua.ing ta.get of the lea.er ca. ca.se a. a.plified disturba.ce in the queue. a.ter a.long period of time, the queue recovers the sta.le sta.e from the disturba.ce, forming a.stra.ghtline-like pa.tern a.a.n, but dista.ces between neighbors grow. Whether the queue ca. keep sta.le or not depends on initia. dista.ce, desired velocity, a.d rela.a.ion time. Furthermore, we ca.ry out convergence a.a.ysis to expla.n the divergence tra.sforma.ion beha.ior a.d confirm the convergence conditions, which is in a.proxima.e a.reement with simula.ions.

The purpose of this pa.er is to present a.systema.ic review of studies tha. used Video Conferencing (VC) intervention for common chronic conditions. Chronic conditions a.count for the ma.ority of poor hea.th, disa.ility, a.d dea.h, a.d for a.ma.or portion of hea.th-ca.e expenditures in the United Sta.es. Innova.ive methods a.d interventions a.e needed to enha.ce ca.e a.d ma.a.ement, improve a.cess to ca.e, improve pa.ient outcomes, na.row hea.th dispa.ities a.d reduce hea.thca.e costs. Video Conferencing could be pa.ticula.ly releva.t in improving hea.th, ca.e ma.a.ement, a.cess a.d cost in the ca.e of chronic illnesses. a.comprehensive litera.ure sea.ch process guided by the PRISMa.sta.ement led to the inclusion of 27 a.ticles mea.uring video conferencing, a. lea.t one chronic illness, a.d pa.ient outcomes for a.ults living in a.community setting. While VC ha. been found to be fea.ible a.d effective, a.low number of ra.domized controlled tria.s limit evidence. In a.dition, studies in this review were not designed to a.dress the question of whether a.cess to ca.e in rura. a.ea. is improved through VC. Hence, more resea.ch is needed.

The development of a.benign environmenta. ca.a.yst for the genera.ion of biodiesel is a. a.ea.of importa.ce to reduce the overa.l usa.e of fossil fuels. In the current work, biocha. wa. produced by slow pyrolysis of Irul wood sa.dust. The optimiza.ion for biocha. genera.ion wa. ca.ried out for different rea.tion tempera.ures a.d hea.ing dura.ions. The biocha. wa. used to prepa.e solid a.id ca.a.ysts by sulfona.ion process. The cha.a.teriza.ion of biocha. a.d the sulfona.ed ca.a.yst were ca.ried out using Elementa. a.a.ysis, Fourier Tra.sform Infra.ed spectroscopy(FTIR), Powder X-ra. Diffra.tion(XRD), Thermo Gra.imetric a.a.ysis(TGa., Sca.ning Electron Microscopy(SEM) a.d Surfa.e a.ea.a.a.yzer(BET). The cha.a.teriza.ion results showed tha. sulfona.ion of biocha. resulted in biocha. ba.ed solid a.id ca.a.yst conta.ning va.ious functiona. a.idic groups like wea. a.idic\\OH groups, strong a.idic\\COOH a.d SO3 H groups. The tota. a.id density a.d sulfonic a.id group density of ca.a.yst were estima.ed a.d showed excellent a.idic sites concentra.ion which gives a.good ca.a.ytic a.tivity for biodiesel production through simulta.eous esterifica.ion a.d tra.sesterifica.ion. The enha.ced ca.a.ytic a.tivity is due to the high a.id density of SO3 H groups a.d the rea.ta.t a.cessibility towa.ds a.idic sites a. well a. the strong a.finity between the hydrophilic rea.ta.ts a.d the neutra. OH groups which a.e bonded with the polycyclic a.oma.ic ca.bon rings. The performa.ce of biocha. ca.a.yst for the production of biodiesel wa. eva.ua.ed by compa.ing the yield obta.ned. The FTIR a.d Ga. Chroma.ogra.hy–Ma.s Spectroscopy(GC–MS) were a.so ca.ried out for the a.a.ysis of biodiesel produced.
