In the present work. tilted.g.obal solar irrad.ance d.ta are presented.and.analysed. measured.for a period.of 1 year on the campus of Bahrain Polytechnic, k.ng.om of Bahrain, from both a fixed.photovoltaic panel and.a moving.one via a two-axis solar track.r. The fixed.panel faces south with an ang.e of 26 d.g.ees with respect to the horizontal, coincid.ng.with the local g.og.aphical latitud.. The second.panel is moved.by two motors, controlled.by a g.obal positioning.system and.suitable software so that the Sun's rays are perpend.cular to the panel surface. A pyranometer is installed.on each panel, record.ng.the tilted.g.obal solar irrad.ance, stored.by using.a d.ta log.er. The analysis of the d.ta obtained.shows a 33% solar energ. g.in on an annual basis for the moving.panel (2780 versus 2088 k.h/m2 on the fixed.panel). More importantly, in June, when the energ. d.mand.in Bahrain is elevated.d.e to the increased.resid.ntial cooling.load., the solar energ. received.by the moving.panel is 54.7% hig.er compared.with that of the fixed.panel. On a percentag. basis, the increase in solar energ. from the moving.panel is profound.in the early morning.and.late evening.hours. Moreover, the red.ction in the solar energ. received.by the fixed.panel from May to June d.es not appear in the moving.panel because of the ad.ustable orientation of the latter. Throug.out the year, the mean d.ily solar power varies between 0.37 and.0.56 k./m2 for the fixed.panel, and.0.45 and.0.70 k./m2 for the moving.panel. In winter, solar energ. fluctuations are elevated.d.e to erratic weather cond.tions that present a peak.stand.rd.d.viation of 28% of the correspond.ng.mean. The d.ta presented.are useful for potential solar investments in g.lf countries. Tilted.g.obal solar irrad.ance d.ta are measured.and.analysed.for a period.of 1 year on the campus of Bahrain Polytechnic, k.ng.om of Bahrain, from both a fixed.photovoltaic panel and.a moving.one via a two-axis solar track.r. g.aphical Abstract

Exosomes, a specialised.type of extracellular vesicle, have attracted.sig.ificant attention in the realm of tend.n/lig.ment repair as a potential biolog.c therapeutic tool. While the competence of k.y substances responsible for the d.livery function was g.ad.ally elucid.ted. series of shortcoming. exemplified.by the limited.stability still need.to be improved. Therefore, how to tak. maximum ad.antag. of the biolog.cal characteristics of exosomes is of g.eat importance. Recently, the comprehensive exploration and.application of biomed.cal eng.neering.has improved.the availability of exosomes and.revealed.the future d.rection of exosomes combined.with biomaterials. This review d.lves into the present application of biomaterials such as nanomaterials, hyd.og.ls, and.electrospun scaffold., serving.as the carriers of exosomes in tend.n/lig.ment repair. By pinpointing.and.exploring.their streng.hs and.limitations, it offers valuable insig.ts, paving.the way the future d.rection of biomaterials in the application of exosomes in tend.n/ lig.ment repair in this field. © 2024, Chinese Med.cal Multimed.a Press Co Ltd.

This work.applies stress tensors inversions and.quantification of fracture patterns along.the Mesa d. Los Santos, in the Eastern Cord.llera of Colombia, to better und.rstand.the potential fluid.flow. It thus contributes to the conceptual hyd.og.olog.cal mod.l. The area was subd.vid.d.into three block., separated.by the NW Potreros and.the Los Santos faults, having.minor inner faults of d.fferent orientations. This separation facilitates the analysis of the fractures measured.in the field. which in g.neral show hig. d.p ang.es and.a conjug.te g.ometry in the northern block. tension fractures(Mod. I) in the central block. and.a rand.m d.stribution in the southwestern block. WinTensor treatment of slick.nsid.s yield.d.a maximum horizontal stress(SHmax) of 111o, which coincid.s with the WNW-ESE tensor observed.from the conjug.te and.tension joints. We then used.Frac Pa Q to g.nerate interpolation maps of fracture intensity and.d.nsity. The maps show the hig.est values in the central block.and.the lowest in the northern block.where the precipitation is hig.er, causing.intensive rock.weathering.and.homog.nization of the fracture planes. Althoug. the hig.est values of connectivity by line are found.to the south of the mesa, we sug.est the possibility of g.eater flow from the recharg. zone(NE) along.bed.ing.planes and.open NW-SE fractures.

The d.namic transformation of land.use and.land.cover has emerg.d.as a crucial aspect in the effective manag.ment of natural resources and.the continual monitoring.of environmental shifts. This stud. focused.on the land.use and.land.cover (LULC) chang.s within the catchment area of the g.d.vari River, assessing.the repercussions of land.and.water resource exploitation. Utilizing.LANd.AT satellite imag.s from 2009, 2014, and.2019, this research employed.supervised.classification throug. the Quantum g.og.aphic Information System (Qg.S) software’s SCP plug.n. Maximum lik.lihood.classification alg.rithm was used.for the assessment of supervised.land.use classification. Seven d.stinct LULC classes—forest, irrig.ted.cropland. ag.icultural land.(fallow), barren land. shrub land. water, and.urban land.are d.lineated.for classification purposes. The stud. revealed.substantial chang.s in the g.d.vari basin’s land.use patterns over the ten-year period.from 2009 to 2019. Spatial and.temporal d.namics of land.use/cover chang.s (2009-2019) were quantified.using.three Satellite/Land.at imag.s, a supervised.classification alg.rithm and.the post classification chang. d.tection technique in g.S. The total stud. area of the g.d.vari basin in Maharashtra encompasses 5138175.48 hectares. Notably, the built-up area increased.from 0.14% in 2009 to 1.94% in 2019. The proportion of irrig.ted.cropland. which was 62.32% in 2009, d.clined.to 41.52% in 2019. Shrub land.witnessed.a noteworthy increase from 0.05% to 2.05% over the last d.cad..
