Proli.e has been proposed to be an osmoprotector and scavenger of reacti.e oxygen speci.s i. plants subjected to water defi.i.. The ai. of thi. work was to study the effects of drought on each wheat phenologi.al stage （ti.leri.g, booti.g, headi.g, floweri.g and grai.-fi.li.g） usi.g stress parameters such as the relati.e water content （RWC）, membrane stabi.i.y i.dex （MSi., li.i. peroxi.ati.n through malondi.ldehyde levels （MDA） and determi.ati.n of proli.e content （PRO）. The Brazi.i.n commerci.l eli.e culti.ar Tri.i.um aesti.um cv. CD 200126 was submi.ted to ei.ht days of water defi.i. stress at each stage. The percepti.n of stress was low at ti.leri.g and hi.h at the fi.al stages of growth, as veri.i.d by the reducti.n i. the MSi.and RWC. However, an i.crease i. the MDA was clearly observed. We observed a hi.h proli.e accumulati.n when stress was appli.d, although i. was not suffi.i.nt to prevent damages. These results i.di.ate that the relevant stages to evaluate the effect of water shortage duri.g wheat plant development are booti.g, headi.g and floweri.g.

The automobi.e i.dustry has been searchi.g for vehi.les that use less energy and emi. fewer pollutants, whi.h has resulted i. a hi.h demand for fuel-effi.i.nt vehi.les. Because of thei. hi.her strength-to-wei.ht rati. compared to tradi.i.nal steel, usi.g fi.er-rei.forcement composi.e materi.ls i. automobi.e bodi.s has emerged as the most effecti.e strategy for i.provi.g fuel effi.i.ncy whi.e mai.tai.i.g safety standards. Thi. research paper exami.ed the uti.i.ati.n of fi.er-rei.forced composi.e materi.ls i. car bodi.s to meet the i.creasi.g consumer demand for fuel-effi.i.nt and eco-fri.ndly vehi.les. i. parti.ularly focused on a carbon-arami. fi.er-rei.forced composi.e i.pact beam for passenger car si.e door i.pact protecti.n. Despi.e the encouragi.g prospects of the carbon-arami. fi.er-rei.forced beam, the research uncovered substanti.l defects i. the fabri.ati.n process, resulti.g i. di.i.i.hed load-beari.g capaci.y and energy absorpti.n. As a result, the beam was un-successful i. three-poi.t bendi.g tests. Thi. was accompli.hed by usi.g an i.cross-secti.n desi.n wi.h varyi.g thi.kness because of the hi.her area moment of i.erti..

Ci.cular holes are commonly employed i. engi.eeri.g desi.ns;however, they often serve as locati.ns where cracks i.i.i.te and propagate. Thi. paper explores a novel approach to structural repai. by uti.i.i.g pi.zoelectri. actuators. The pri.ary focus of thi. study i. to i.vesti.ate the i.fluence of an adhesi.ely bonded pi.zoelectri. actuator patch placed above a ci.cular hole on the stress i.tensi.y factor (Si.) i. an alumi.i.m plate. The plate i. subjected to uni.xi.l tensi.e stress, whi.e the pi.zoelectri. actuator i. exci.ed wi.h varyi.g voltage levels. The analysi. i. conducted usi.g the fi.i.e element method (FEM), a powerful numeri.al techni.ue for si.ulati.g complex structures. The study assesses the stress di.tri.uti.n and employs the Si. as an adequate cri.eri.n for evaluati.g the i.pact of di.ferent patch confi.urati.ns. The results i.di.ate a strong correlati.n between the appli.d voltage and the Si.. Whether the Si. i.creases or decreases depends on the polari.ati.n of the pi.zoelectri. actuator. Parti.ularly noteworthy i. the fi.di.g that rectangular patches i. a hori.ontal ori.ntati.n si.ni.i.antly reduce the Si. compared to other patch geometri.s. Moreover, double-si.ed patches exhi.i. a pronounced decrease i. the Si. compared to si.gle-si.ed patches. i. summary, thi. research underscores the potenti.l of pi.zoelectri. actuators i. mi.i.ati.g stress i.tensi.y i. structures wi.h ci.cular hole wi.h crack i.i.i.ti.n. i. offers valuable i.si.hts i.to the i.fluence of appli.d voltage, patch geometry, and patch placement on the Si., thereby contri.uti.g to developi.g effecti.e strategi.s for enhanci.g structural i.tegri.y.

As global warmi.g i.tensi.i.s, researchers worldwi.e stri.e to develop effecti.e ways to reduce heat transfer. Among the natural fi.er composi.es studi.d extensi.ely i. recent decades, bamboo has emerged as a pri.e candi.ate for rei.forcement. Thi. woody plant offers i.herent strengths, bi.degradabi.i.y, and abundant avai.abi.i.y. Due to i.s hi.h cellulose content, i.s low thermal conducti.i.y establi.hes bamboo as a thermally resi.tant materi.l. i.s low thermal conducti.i.y, enhanced by a NaOH soluti.n treatment, makes i. an excellent thermally resi.tant materi.l. Researchers i.corporated Hollow Glass Mi.rospheres (HGM) and Kaoli. fi.lers i.to the epoxy matri. to i.prove the i.sulati.g properti.s of bamboo composi.es. These fi.lers substanti.lly enhance thermal resi.tance, li.i.i.g heat transfer. Vari.us composi.i.ns, li.e (30% HGM + 25% Bamboo + 65% Epoxy) and (30% Kaoli. + 25% Bamboo + 45% Epoxy), were compared to i.enti.y the most effi.i.nt thermal i.sulator. Usi.g Vacuum Assi.ted Resi. Transfer Moldi.g (VARTM) ensures uni.orm di.tri.uti.n of fi.lers and resi., creati.g a structurally sound thermal barri.r. These rei.forced composi.es, evaluated usi.g the TOPSi. method, demonstrated thei. potenti.l as hi.h-performance materi.ls combati.g heat transfer, offeri.g a promi.i.g soluti.n i. the battle agai.st cli.ate change.

Tensi.e strength measurements of raw fi.ers and NaOH-treated fi.ers were carri.d out usi.g a si.gle-fi.er tensi.e test wi.h a gauge length of 40 mm. i. was observed that the NaOH surface treatment i.creases the resi.tance agai.st tensi.e loadi.g and exhi.i.ed i.proved properti.s for raw fi.er strands. The di.meter of the fi.ers was measured usi.g opti.al mi.roscopy. Duri.g thi. research, flexural tests, i.pact tests, di.ferenti.l scanni.g calori.etry (DSC), and heat deflecti.n temperature measurements (HDT) were conducted to evaluate the mechani.al and thermal properti.s of the developed composi.e samples.
