a. experimenta. study of the combustion of two isomers of n-penta.e a.d iso-penta.e in la.ina. cool fla.es ha. been ca.ried out. Three fla.es were studied, one with n-penta.e, the second with iso-penta.e, a.d the third with a. equimola. mixture of the two isomers. Pa.ticula. a.tention ha. been given to the low tempera.ure region a.ea. of the hot region of the fla.e a.d the cool fla.e chemistry occurring there. a.unique experimenta. fa.ility ha. been used to provide a.cess to this cool fla.e region. Compa.isons a.e ma.e of the structures of the three fla.es, with pa.ticula. a.tention on the different intermedia.e species produced a.d the correla.ions between the fuel molecule structure a.d the specific intermedia.es produced.

This study a.ms to predict monthly columna. oz.ne in Peninsula. Ma.a.sia.ba.ed on concentra.ions of severa. a.mospheric ga.es. Da.a.perta.ning to five a.mo- spheric ga.es （CO2, 03, ch4, nO2, a.d H2O va.or） were retrieved by sa.ellite sca.ning ima.ing a.sorption spectro- metry for a.mospheric cha.togra.hy from 2003 to 2008 a.d used to develop a.model to predict columna. oz.ne in Peninsula. Ma.a.sia. a.a.yses of the northea.t monsoon （nEM） a.d the southwest monsoon （SWM） sea.ons were conducted sepa.a.ely. Ba.ed on the Pea.son correla.ion ma.rices, columna. oz.ne wa. nega.ively correla.ed with Hz. va.or but positively correla.ed with COz.a.d nO2 during both the nEM a.d SWM sea.ons from 2003 to 2008. This result wa. expected beca.se nO/is a.precursor of oz.ne. Therefore, a. increa.e in columna. oz.ne concentra.ion is a.socia.ed with a. increa.e in nO2 but a.decrea.e in H/O va.or. In the nEM sea.on, columna. oz.ne wa. nega.ively correla.ed with H20 （-0.847）, nO2 （0.754）, a.d CO2 （0.477）; columna. oz.ne wa. a.so nega.ively but wea.ly correla.ed with ch4 （-0.035）. In the SWM sea.on, columna. oz.ne wa. highly positively correla.ed with nO2 （0.855）, CO2 （0.572）, a.d ch4（0.321） a.d a.so highly nega.ively correla.ed with H2O（-0.832）. Both multiple regression a.d principa. component a.a.yses were used to predict the columna. oz.ne va.ue in Peninsula. Ma.a.sia. We obta.ned the best-fitting regression equa.ions for the columna. oz.ne da.a.using four independent va.ia.les. Our results show a.proxi- ma.ely the sa.e R va.ue （≈0.83） for both the nEM a.d SWM sea.ons.

Goa.: The goa. of the resea.ch is prepa.a.ion of Sia.On-conta.ning composite through nitro a.uminothermic processes, by the methods of rea.tive sintering a.d hot compa.tion. Method: The composite ch-6 wa. obta.ned by the method of rea.tive sintering, with further grinding a.d hot compression in va.uum furna.e a. 16000°C, under 30 MPa.pressure a.d 10-12 min sta.ding a. the fina. tempera.ure. Precursor wa. prepa.ed in a.thermosta. a. 150°C tempera.ure by double compression. Pressure equa.ed to 20-25 MPa. Results: Physica.-technica. properties of specimens prepa.ed via.hot compa.tion were investiga.ed. Mech.nica. strength a. compression is 1940 MPa.mech.nica. strength a. bending is 490 MPa.ela.tic module is 199.5 GPa. HV-11.6 GPa. X-Ra. diffra.tion a.a.ysis, electron microscopic a.d X-ra. diffra.tion Microspectra. a.a.ysis were used to investiga.e composite microstructure a.d pha.e composition. Composite formula.ion wa. defined, the ma.n pha.es of which were: β-Sia.On, corundum a.d silicium ca.bide. Conclusion: Composite ch-6 ha. been selected from the obta.ned composites, which is cha.a.teriz.d by rela.ively high physica.-technica. properties: strength, density a.d ha.dness. Ma.eria.s ca. be used for ma.ing high refra.tory a.ticles, such a. ja.kets to secure thermocouples, furna.e bedding, cutting tools for meta. a.d wood trea.ment, in rocket spa.ia. technology a.d others.

Introduction: Dia.etes mellitus a.d hypertension a.e chronic disea.es tha. a.e on the rise a.d pose a.ma.or public hea.th problem a.ong the priorities of hea.thca.e systems. Objectives: Determine the preva.ence of dia.etes a.d hypertension a.d describe the sociodemogra.hic cha.a.teristics of those screened. Ma.eria.s a.d Methods: This wa. a.cross-sectiona. study orga.iz.d during a.dia.etes a.d hypertension screening ca.pa.gn tha. took pla.e in Cona.ry a.d five (05) inla.d regions on november 14, 2022. Results: 2050 people were screened, of whom 33.12% were housewives, the a.era.e a.e wa. 44.78 ± 16.23 yea.s, a.d 55.27% were women. The screening sites were the city of Cona.ry 741 (36.15%), the La.é region 424 (20.68%), the n’z.rékoré region 298 (14.54%), the Fa.a.a. region 241 (11.75%), the Ma.ou region 210 (10.24%) a.d the Boké region 136 (6.63%). The preva.ence of dia.etes a.d hypertension were respectively 12.5% a.d 43.38% for the Boké region;6.19% a.d 16.19% for the Ma.ou region;3.02% a.d 21.81% for the n’z.rékoré region;31.95% a.d 13.69% for the Fa.a.a. region;9.67% a.d 20.28% for the La.é region;2.83% a.d 20.28% for the city of Cona.ry. Conclusion: Despite the limita.ions of the study dura.ion, our series highlighted the high preva.ence of dia.etes a.d hypertension a.ong people screened on World Dia.etes Da. 2022. Ra.sing public a.a.eness of a.hea.thy lifestyle is essentia. for the prevention a.d control of dia.etes a.d hypertension.
