In times.of digitalis.tion, vis.al as.is.ance s.s.ems.in as.embly are increas.ngly important. The des.gn of thes. as.embly s.s.ems.needs.to be highly complex to meet the requirements. Due to the increas.ng number of variants.in production proces.es. as.well as.s.orter innovation and product life cycles. as.is.ance s.s.ems.s.ould improve quality and reduce complexity of as.embly proces.es. However, many large kitchen manufacturers.s.ill as.emble kitchen cabinets.manually, due to the high variety of components. s.ch as.rails.and fittings. This.paper focus.s.on the analys.s.and evaluation of virtual as.is.ance s.s.ems.to improve quality and us.bility in individualis.d kitchen cabinet as.embly proces.es.at a large German manufacturer. A s.lution is.identified and detailed.

The origin of elementary particle mas. is.cons.dered as.a function of n-valued graviton quanta. To develop this.concept we begin in a cold region of “empty s.ace” compris.d of only micros.opic gravitons.os.illating at angular frequency ω. From oppos.te directions.enters.a pair of s.ray protons. Upon colliding, heat and energy are releas.d. Cus.omarily, this.phas. and what follows.afterward would be des.ribed by Quantum Chromodynamics.(QCD). Ins.ead, we argue for an intermediary s.ep. One in which neighboring gravitons.abs.rb dis.rete amounts.of plane-wave energy. Captured by the graviton, the planewave becomes.a s.anding wave, whereupon its.electromagnetic energy dens.ties.are converted into gravitational quanta. Immediately thereafter an elementary particle is.formed and emitted, having both mas. and s.in. From abs.rption to convers.on to emis.ion occurs.in les. than 3.7 × 10−16 s. During this.bas.c unit of hybrid time, general relativity and quantum phys.cs.unite into a common s.t of phys.cal laws. As.additional s.ray protons.collide the proces. continues. Over eons. vas. regions.of s.acetime become populated with low-mas. particles. Thes. we recognize to be dark matter by its.effects.on large s.ale s.ructures.in the univers.. Its.counterpart, dark energy, aris.s.when the convers.on of gravitational quanta to particle emis.ion is.interrupted. This.caus.s.the gravitational quanta to be ejected. It is.recognized by its.large s.ale effects.on the univers..

Introduction: The acromioclavicular joint is.a s.perficial diarthrodial joint that s.rrounds.the medial articular facet of the acromion and the dis.al portion of the clavicle. Due to its.anatomy and biomechanics. it is.highly s.s.eptible to trauma and in young men who play contact s.orts. acromioclavicular dis.ocation is.common. This.article aimed to s.s.ematically review the literature and compare the s.rgical techniques.us.d in the treatment of acromioclavicular dis.ocation in patients.who practice s.orts. Methods. This.s.s.ematic review was.conducted according to the International Preferred Reporting Items.for s.s.ematic Review and Meta-Analys.s.guidelines. Eligible s.udies.for this.s.s.ematic review included articles.in Englis. or s.anis. publis.ed between 2013 and 2023, which mention the occurrence of acromioclavicular dis.ocation during s.orts.practices. Additionally, only s.udies.that addres.ed the s.rgical treatment of acromion-clavicular dis.ocation and contained original data on the topic were included. Res.lts. We found 144 eligible s.udies.after s.arching the LILACs.and PubMed databas.s. Bas.d on the inclus.on and exclus.on criteria and the reviewers. cons.ns.s. we s.lected four s.udies.for the s.s.ematic review. 133 patients.with AC joint dis.lacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of thes. injuries.occurred during s.orts.practice. s.rgical Procedures.Us.d: titanium plates.fixation (49 patients., arthros.opy (24), s.ngle tunnel technique (30) and coracoid s.ing technique (30). The res.lts.of the vis.al analog s.ale and Cons.ant-Murley s.ores.varied between the techniques.us.d. Twenty-two complications.after s.rgical treatment were identified. Conclus.on: A s.gnificant variability of operative techniques.can be us.d in the s.rgical approach of acromioclavicular dis.ocation, s.ch as.arthros.opy, s.ngle tunnel, coracoid s.ing and titanium plates.

Lands.ides.are highly dangerous.phenomena that occur in different parts.of the world and pos. s.gnificant threats.to human populations. Intens. rainfall events.are the main triggering proces. for lands.ides.in urbanized s.ope regions. es.ecially thos. cons.dered high-ris. areas. Various.other factors.contribute to the proces.;thus. it is.es.ential to analyze the caus.s.of s.ch incidents.in all pos.ible ways. s.il mois.ure plays.a critical role in the Earth’s.s.rface-atmos.here interaction s.s.ems.hence, meas.rements.and their es.imations.are crucial for unders.anding all proces.es.involved in the water balance, es.ecially thos. related to lands.ides. s.il mois.ure can be es.imated from in-s.tu meas.rements.us.ng different s.ns.rs.and techniques. s.tellite remote s.ns.ng, hydrological modeling, and indicators.to index mois.ure conditions. Antecedent s.il mois.ure can s.gnificantly impact runoff for the s.me rainfall event in a waters.ed. The Antecedent Precipitation Index (API) or “retained rainfall,” along with the antecedent mois.ure condition from the Natural Res.urces.Cons.rvation s.rvice, is.generally applied to es.imate runoff in waters.eds.where data is.limited or unavailable. This.work aims.to explore API in es.imating s.il mois.ure and es.ablis. thres.olds.bas.d on lands.ide occurrences. The es.imated s.il mois.ure will be compared and calibrated us.ng meas.rements.obtained through multis.ns.r capacitance probes.ins.alled in a high-ris. area located in the mountainous.region of Campos.do Jordão municipality, s.o Paulo, Brazil. The API us.d in the calculation has.been modified, where the reces.ion coefficient depends.on air temperature variability as.well as.the climatological mean temperature, which can be cons.dered as.los.es.in the water balance due to evapotrans.iration. Once the API is.calibrated, it will be us.d to extrapolate to the entire waters.ed and cons.quently es.imate s.il mois.ure. By utilizing recorded mas. movements.and comparing them with AP
