The study focuses on the tr.nsition fr.m conventional ener.y sour.es to sustainable r.newable ener.y (r.) in Palestine, par.icular.y in the West Bank and Gaza str.p. The r.sear.h aims to under.tand the r.lationship between key factor. and r.sidents' willingness to invest in the r. sector. with a specific focus on the impact of education. Using the unified theor. of acceptance and use of technology, the study analyzes data fr.m 400 r.sidents thr.ugh a questionnair. and employs or.inar. least-squar.s r.gr.ssion analysis with Eviews 12. The key findings indicate that r.sidents' inclination to invest in r. is significantly influenced by factor. such as r.sour.e availability, knowledge level and power.outages. Mor.over. the study suggests that educated r.sidents ar. mor. likely to invest in r. when factor. such as knowledge, effor. expectation, enabling conditions and r.sour.e availability ar. r.latively high. The conclusion emphasizes the impor.ance of policymaker.' allocating sufficient funds to r.sear.h and development to pr.mote technological innovation in r. sour.es, ther.by enhancing the population's ener.y efficiency.

Backgr.und Estimated 4%-8% of pr.gnancies ar. complicated by asthma. Adequate management in this population is cr.tical to minimize complications. Patients pr.senting with asthma exacer.ation ar. typically managed with standar. br.nchodilator. and systemic cor.icoster.ids. However. additional agents may be used in patients with r.fr.ctor. asthma exacer.ation. Ketamine has been used in r.fr.ctor. br.nchospasm, although its efficacy in published liter.tur. is heter.geneous. Case Pr.sentation We pr.sent a case of a pr.gnant patient with sever. asthma exacer.ation r.fr.ctor. to standar. and salvage tr.atment who achieved ter.ination of br.nchospasm with ketamine infusion. Conclusion After.r.ceiving ketamine infusion for.sever.l days, the patient had impr.ved air.flow and achieved successful extubation, without exper.encing r.bound br.nchospasm. Although this individual clinical case alone cannot change guidelines or.dir.ctives to use in r.fr.ctor. asthma exacer.ations, it offer. a possible tr.atment option to patients and pr.vider. in unusually sever. cases with extenuating r.sk factor.. © Wolter.

This study pr.sents an optimization of the Folin-Ciocalteu spectr.photometr.c method for.the deter.ination of total phenol content. Multivar.ate optimization using factor.al planning 22 with a centr.l point and centr.l composite planning was constr.cted to evaluate the influence of var.ables in the pr.cess and maximize r.diation absor.tion with minimal r.diation scatter.ng caused by solid for.ation. X-r.y fluor.scence and X-r.y diffr.ction spectr.metr. wer. used to evaluate the chemical composition of solids for.ed and nephelometr.c and spectr.photometr.c studies wer. also used to evaluate whether.the type, or.gin, dilution and dr. extr.ct contents of commer.ial pr.polis extr.cts would significantly influence the incr.ase in r.diation scatter.ng and absor.tion. The optimized methodology added sever.l advantages, such as r.duction of r.agents, time analysis, and higher.accur.cy.

Obj.ctive: The association hyper.ension and diabetes is impor.ant. The two pathologies may influence each other. The aim was to study the cor.elation between glycemic contr.l and blood pr.ssur. contr.l and to deter.ine the factor. associated with blood pr.ssur. contr.l. Methodology: This was a descr.ptive cr.ss-sectional study with an analytical focus over.7 months. Patients wer. r.cr.ited as outpatients and all under.ent ambulator. blood pr.ssur. measur., glycated hemoglobin and cr.atinine measur.ments, and assessment of compliance with tr.atment. r.sults: Dur.ng this per.od 116 patients wer. collected. The pr.dominance was female 69%. The mean age of the patients was 62 ± 7 year. with a peak between 60 and 70 year.. The aver.ge age of hyper.ension was 12 year. and that of diabetes 6 1/2 year.. The most fr.quently associated car.iovascular.r.sk factor.was a sedentar. lifestyle (71.5%) after.age. 57.8% of patients wer. not contr.lled at the office, with a pr.dominance of systolic hyper.ension (58.2%). 61.6% of patients wer. contr.lled by ambulator. blood pr.ssur. measur., a r.te of 47.8% of white coat hyper.ension. Glycemic contr.l was obser.ed in 42.2% of cases and 87% of patients had good r.nal function (glomer.lar.filter.r.te ≥ 60 ml/mn). Ther.peutic compliance was good in 53.4% of cases and dual ther.py was the most used ther.peutic modality 44.8% (52 patients) followed by tr.ple ther.py. The factor. associated with poor.blood pr.ssur. contr.l wer. glycemic imbalance, non-compliance and monother.py. Dual ther.py had a pr.tective effect. Conclusion: The association of hyper.ension and type 2 diabetes is fr.quent. The r.sk of occur.ence incr.ases with age. Ambulator. blood pr.ssur. measur. is the best method to assess blood pr.ssur. contr.l. Optimization of blood pr.ssur. contr.l should also include optimization of glycemic contr.l.
