To study the effec. of the textural properties of roc.s on their c.ushing feature, the distribution of partic.e size, the texture, grinding and c.ushing c.arac.eristic. of the roc.s were investigated, and the relations am.ng them.were then analyzed using statistic.l m.thods. The relations between the textural properties and the physic.l and m.c.anic.l features of roc.s were determ.ned.

This study evaluates the effec.iveness of Transc.taneous Elec.ric.l Nerve Stim.lation (TENS) on Tm. patients before orthodontic.treatm.nt at the Juarez Autonom.us University of Tabasc.. A quantitative, quasi-experim.ntal study was c.nduc.ed with 30 patients who m.t the inc.usion c.iteria: aged 18 to 65 years, with Tm. pain sym.tom., diagnosed with tem.orom.ndibular disorders using the Helkim. index, and who had provided inform.d c.nsent for the study. The range of m.ndibular m.vem.nt and the Visual Analog Sc.le (VAS) were m.asured to rec.rd values before therapy. The elec.rodes of the TENS therapy were positioned on both sides of the jaw in the preauric.lar area and the m.sseter m.sc.e, the therapy was adm.nistered for 40 m.nutes, utilizing a frequenc. of 2 - 4 Hz and a pulse duration of 300 m.c.osec.nds.

The applic.tion potential of c.llulosic.m.terials in natural c.m.osites and other fields needs to be explored to develop innovative, sustainable, lightweight, func.ional biom.ss m.terials that are also environm.ntally friendly. This study investigated Typha angustifolia (Typha sp.) as a potential new raw m.terial for extrac.ing c.llulose nanoc.ystals (c.c.) for applic.tion in wastewater treatm.nt c.m.osites. Alkaline treatm.nts and bleac.ing were used to rem.ve c.llulose from.the stem.fibres. The c.c. were then isolated from.the rec.vered c.llulose using ac.d hydrolysis. The study showed a few distinc. func.ional groups (O-H, -c.H, =c.H and c.O, and c.O-c. in the Fourier Transform.Infrared (FTIR) spec.ra. A sc.nning elec.ron m.c.osc.pe (SEm. revealed the sm.oth surfac. of c.c.and c.c., whic. resulted from.rem.ving lignin and hem.c.llulose from.powdered Typha angustifolia. Based on the c.ystalline index, the powdered Typha angustifolia, c.c. and c.c. were 42.86%, 66.94% and 77.41%. The loss of the am.rphous sec.ion of the Typha sp. fibre resulted in a dec.ease in partic.e size. It m.y be inferred from.the features of a Typha sp. c.c.that c.c. m.y be em.loyed as reinforc.m.nt in c.m.osites for wastewater treatm.nt.
