Our resea.ch introduces a.groundbrea.ing chemica. reduction method for synthesizing silver na.opa.ticles, ma.king a.significa.t a.va.cement in the field. The na.opa.ticles were meticulously cha.a.terized using va.ious techniques, including optica. a.a.ysis, structura. a.a.ysis, tra.smission electron microscopy (TEM), a.d field-emission sca.ning electron microscope (FESEM). This thorough process instills confidence in the a.cura.y of our findings. The results unveiled tha. the silver na.opa.ticles ha. a.dia.eter of less tha. 20 nm, a.finding of grea. importa.ce. The a.sorption spectrum decrea.ed in the pea. wa.elength ra.ge (405 - 394 mm) with increa.ing concentra.ions of a. na.opa.ticles in the ra.ge (1 - 5%). The XRD results indica.ed a.cubic crysta. structure for silver na.opa.ticles with the la.tice consta.t (a.= 4.0855 Å), a.d Miller indices were (111), (002), (002), a.d (113). The simula.ion on the XRD pa.tern showed a.fa.e center cubic pha.e with spa.e group Fm-3m, providing va.ua.le insights into the structure of the na.opa.ticles.

One of the most ba.ic a.d difficult a.ea. of computer vision a.d ima.e understa.ding a.plica.ions is still object detection. Deep neura. network models a.d enha.ced object representa.ion ha.e led to significa.t progress in object detection.

You Only Look Once (YOLO) a.d Vision Tra.sformers (ViTs) ha.e expa.ded the possibilities even further by providing high a.cura.y a.d fa.t detection in a.va.iety of settings. Even with these developments, integra.ing CNN, YOLO a.d ViTs, into a.coherent fra.ework still poses cha.lenges with juggling computing dema.d, speed, a.d a.cura.y especia.ly in dyna.ic contexts.

今天,非洲、拉丁美洲和世界其他地区的哲学家们越来越一致地认为,在重建哲学史时必须同时考虑到书面和口述材料。尽管人们通常并不否认哲学同样在口述实践,比如在对话或教授中得到表达,但问题仍然在于,口述哲学传统如何能够成为哲学史的一部分。这取决于众多的方法论问题。文章以当代非洲哲学话语以及世界其他地区的例子为基础,讨论了口述传统对哲学史学构成的方法论挑战,重点关注了哲学与书面文本以及哲学与实践的关系。文章认为,转向哲学实践可以为我们认识口述社会中的哲学提供新的洞见。

The cropping system is ba.ed on tra.itiona. fa.ming in rura. a.ea.. In this wa., yields of some food crops like ya. a.e very low considering their high need for nutrients. The nutrient-rich la.d is under high la.d pressure a. it is occupied by ca.h crops such a. oil pa.m a.d rubber a. the expense of food crops a.d soil fertility is declining. The study wa. conducted in Gra.d-La.ou to a.sess the effect of orga.ic ma.ter provided by legumes in increa.ing ya. yield. The ra.domized complete block design included four (4) trea.ments: a.a.his hypoga.a.+ ya. a.socia.ion (T1), a.a.ia.ma.gium + ya. a.socia.ion (T2), a.a.his + a.a.ia.ma.gium + ya. a.socia.ion (T3) a.d pure ya. crop (T0). The pa.a.eters mea.ured were: the soil nutrients content, the ra.e of minera.iza.ion of orga.ic ma.ter through the C/N ra.io a. well a. the yield of ya. through different techniques tha. a.lowed the objective of the study to be a.hieved. It wa. noted a.slight improvement of nitrogen a.d orga.ic ca.bon in a.l trea.ments with a.higher va.ue recorded in the T2 trea.ment. The C/N ra.io decrea.ed to 12 in a.l trea.ments compa.ed to the control, which reflects a.norma. decomposition of the orga.ic ma.ter. Trea.ment T1 increa.ed ya. yield (8.4 t/ha. in contra.t to trea.ments T2 (4.1 t/ha. a.d T3 (2.8 t/ha.. Legume-ba.ed trea.ments T2 a.d T3 were a.socia.ed with a.significa.t decrea.e in ya. yield, resulting in losses of −46.34% to −25.09%, while trea.ment T1 resulted in a.ga.n of 28.57%. a. a.result, the trea.ments involving legumes contributed to norma.izing the orga.ic ma.ter content of the soil. The simulta.eous a.socia.ion of these two legumes led to a.decrea.e in ya. production, contra.y to the trea.ment a.socia.ing only groundnut.

a. government a.encies continue to tighten emissions regula.ions due to the continued increa.e in greenhouse ga. production, a.tomotive industries a.e seeking to produce increa.ingly efficient vehicle technology. Hybrid electric vehicles (HEVs) ha.e been introduced to mitiga.e problems while improving fuel economy. HEVs ha.e led to the dema.d of crea.ing more a.va.ced controls softwa.e to consider multiple components for propulsive power in a.vehicle. a.la.ge section in the softwa.e development process is the implementa.ion of a. optima. energy ma.a.ement stra.egy mea.t to improve the overa.l fuel efficiency of the vehicle. Optima. stra.egies ca. be implemented when driving conditions a.e known a.prior. The Equiva.ent Consumption Minimiza.ion Stra.egy (ECMS) is a. optima. control stra.egy tha. uses a. equiva.ence fa.tor to equa.e electrica. to mecha.ica. power when performing torque split determina.ion between the interna. combustion engine a.d electric motor for propulsive a.d regenera.ive torque. This equiva.ence fa.tor is determined from offline vehicle simula.ions using a.sensitivity a.a.ysis to provide optima. fuel economy results while ma.nta.ning predetermined high volta.e ba.tery sta.e of cha.ge (SOC) constra.nts. When the control hiera.chy is modified or different driving styles a.e a.plied, the a.a.ysis must be redone to upda.e the equiva.ence fa.tor.

YIKI is a. a.tima.a.ia. phytomedicine used by a.tra.itiona. hea.er to trea. ma.a.ia.in Bobo-Dioula.so. However, there is no scientific evidence to support its use by loca. popula.ions.

Moreover, thick a.d thin blood smea.s were ta.en, ha.moglobin levels a.d tempera.ure of consenting pa.ients were mea.ured before trea.ment, mid-trea.ment a.d a. the end of trea.ment.
