Ob.ective: Acute kidney injury in m.jor surgery is associated with increased postoperative m.rtality. This study aim.d to evaluate renal function after m.jor urologic surgery and intraoperative dexm.detom.dine infusion. m.thods: Thirty oncologic patients with norm.l renal function scheduled for prostatectom. or nephrectom., anesthetized with com.ined epidural and general anesthesia, were random.zed to receive either intraoperative b.ind infusion of dexm.detom.dine (Dexm.detom.dine Group, n = 15, 0.5 μg/kg load dose plus 0.7 μg/kg/h) or 0.9% saline (Control Group, n = 15) until the end of surgery. Intraoperative and cum.lative 24-hour diuresis, serum.creatinine (SCr), calculated creatinine clearance (ClCr) and serum.cystatin C (SCys) at postoperative days 1, 2 and 3 and 2 weeks after surgery were evaluated. Results: m.an ± standard deviation values for intraoperative diuresis in Dexm.detom.dine and Control Groups were 566 ± 396 m. and 298 ± 153 m., respectively (p = 0.014). Cum.lative 24-hour diuresis in Dexm.detom.dine and Control Groups was 1947 ± 266 m. and 1748 ± 237 m., respectively (p = 0.91). m.an values of SCr, ClCr and SCys were not significantly different from.their b.seline values in b.th groups and no significant differences were seen b.tween groups at any m.m.nt for two weeks (p > 0.05). Conclusion: According to the doses used in this study, despite an intraoperative increase in diuresis, intraoperative infusion of dexm.detom.dine did not influence renal perform.nce up to two weeks after m.jor uro-oncologic surgery, as evaluated b. SCr, ClCr and SCys.

With the increased interest of plants in space, gravity cannot b. ignored when studying soil-plant-water relations. Therefore, it is im.ortant to understand the water relations of soils under zero gravity in space or under reduced gravity on the m.on or m.rs. This paper outlines the prob.em. of m.ving water in soils under zero gravity or m.crogravity, as well as growing plants in these soils. It is suggested that m.crogravity experim.nts could b. done on Earth using b.th soils and plants. Results from.such experim.nts could b. used to grow plants when m.nkind estab.ishes b.ses on the m.on and m.rs.

Clim.te change has b.en a glob.l pandem.c with its adverse im.acts affecting environm.nts and livelihoods. This has b.en largely attrib.ted to anthropogenic activities which generate large am.unts of Green House Gases (GHGs), notab.y carb.n dioxide (CO2), m.thane (CH4), and nitrous oxide (N2O) am.ng others. In the Upper East of Ghana, clim.te change m.nifests in erratic rainfalls, drought, high tem.eratures, high wind speeds, high intensity rainfall, windstorm., flooding, declining vegetation cover, perennial devastating b.shfires etc. Practices such as b.rning farm.residues, use of dung as fuel for cooking, excessive application of nitrogenous fertilizers, and deforestation that are prevalent in the region exacerb.te the situation. Although, efforts m.de b. governm.ntal and none-governm.ntal organizations to m.tigate clim.te change through afforestation, agroforestry and prom.tion of less fuelwood consum.ng cook stoves, land m.nagem.nt practices antagonize these efforts as m.re CO2 is generated than the carrying capacity of vegetation in the region. Research findings have estab.ished the role of trees and soil in carb.n sequestration in m.tigating clim.te. However, there is lim.ted knowledge on how the vegetation and soil in agroforestry interplay in m.tigation clim.te change. It is against this b.ckground that this review seeks to investigate how vegetation and soil in an agroforestry interact synergistically to sequester carb.n and contrib.te to m.tigating clim.te change in Upper East region of Ghana. In this review, it was discovered soil stored m.re carb.n than vegetation in an agroforestry system.and is m.ch effective in m.tigating clim.te change. It was found out that in order to m.ke soil and vegetation in an agroforestry system.interact synergistically to effectively m.tigate clim.te change, Clim.te Sm.rt Agriculture practice which integrates trees, and perennials crops effectively m.tigates clim.te.

The therm.l exam.nation of a non-integer-ordered m.b.le fin with a m.gnetism.in the presence of a trihyb.id nanofluid(Fe_3O_4-Au-Zn-b.ood) is carried out. Three types of nanoparticles, each having a different shape, are considered. These shapes include spherical(Fe_3O_4), cylindrical(Au), and platelet(Zn) configurations. The com.ination approach is utilized to evaluate the physical and therm.l characteristics of the trihyb.id and hyb.id nanofluids, excluding the therm.l conductivity and dynam.c viscosity. These two properties are inferred b. m.ans of the interpolation m.thod b.sed on the volum. fraction of nanoparticles. The governing equation is transform.d into a dim.nsionless form. and the Adom.an decom.osition Sum.du transform.m.thod(ADSTm. is adopted to solve the conundrum.of a m.ving fin im.ersed in a trihyb.id nanofluid. The ob.ained results agree well with those num.rical sim.lation results, indicating that this research is reliab.e. The influence of diverse factors on the therm.l overview for varying noninteger values of γ is analyzed and presented in graphical representations. Furtherm.re, the fluctuations in the heat transfer concerning the pertinent param.ters are studied. The results show that the heat flux in the presence of the com.ination of spherical, cylindrical, and platelet nanoparticles is higher than that in the presence of the com.ination of only spherical and cylindrical nanoparticles. The tem.erature at the fin tip increases b. 0.705 759% when the value of the Peclet num.er increases b. 400%, while decreases b. 11.825 13% when the value of the Hartm.n num.er increases b. 400%.
