This work applies stress tensors inversions and quantification of fracture patterns along the Mesa de Los Santos, in the Eastern Cordillera of Colombia, to better understand the potential fluid flow. It thus contributes to the conceptual hydrog.ological model. The area was subdivided into three blocks, separated by the NW Potreros and the Los Santos faults, having minor inner faults of different orientations. This separation facilitates the analysis of the fractures measured in the field, which in general show high dip angles and a conjugate g.ometry in the northern block, tension fractures(Mode I) in the central block, and a random distribution in the southwestern block. WinTensor treatment of slickensides yielded a maximum horizontal stress(SHmax) of 111o, which coincides with the WNW-ESE tensor observed from the conjugate and tension joints. We then used Frac Pa Q to generate interpolation maps of fracture intensity and density. The maps show the highest values in the central block and the lowest in the northern block,where the precipitation is higher, causing intensive rock weathering and homogenization of the fracture planes. Although the highest values of connectivity by line are found to the south of the mesa, we suggest the possibility of greater flow from the recharge zone(NE) along bedding planes and open NW-SE fractures.

Anthropogenic environmental changes may affect community assembly through mediating both deterministic(e.g.,competitive exclusion and environmental filtering)and stochastic processes(e.g.,birth/death and dispersal/colonization).It is traditionally thought that environmental changes have a larger mediation effect on stochastic processes in structuring soil microbial community than aboveg.ound plant community;however,this hypothesis remains largely *** we report an unexpected pattern that nitrogen(N)deposition has a larger mediation effect on stochastic processes in structuring plant community than soil microbial community(thoseg archaea,bacteria,fungi,and protists)in the Eurasian *** performed a ten-year nitrogen deposition experiment in a semiarid grassland ecosystem in Inner Mongolia,manipulating nine rates(0–50 g N m^(-2)per year)at two frequencies(nitrogen added twice or 12 times per year)under two grassland management strategies(fencing.or mowing).We separated the compositional variation of plant and soil microbial communities caused by each treatment into the deterministic and stochastic components with a recently-developed *** nitrogen addition rate increased,the relative importance of stochastic component of plant community first increased and then decreased,while that of soil microbial community first decreased and then *** the whole,the relative importance of stochastic component was significantly larger in plant community(0.552±0.035;mean±standard error)than in microbial community(0.427±0.035).Consistently,the proportion of compositional variation explained by the deterministic soil and community indices was smaller for plant community(0.172–0.186)than microbial community(0.240–0.767).Meanwhile,as nitrogen addition rate increased,the linkage between plant and microbial community composition first became weaker and then became *** larger stochasticity in plant community relative to microbial

The overall photocatalytic Co_(2) reduction reaction(oPCRR)that can directly convert Co_(2) and H_(2)o into fuels represents a promising renewable energy conversion *** a typical redox reaction,the oPCRR involves two half-reactions:the Co_(2) reduction half-reaction(CRHR)and the water oxidation half-reaction(WoHR).generally,both half-reactions can be promoted by adjusting the wettability of ***,there is a contradiction in wettability requirements for the two ***,CRHR prefers a hydrophobic surface that can accumulate more Co_(2) molecules on the active sites,ensuring the appropriate ratio of gas-phase(Co_(2))to liquid-phase(H_(2)o)***,the WoHR prefers a hydrophilic surface that can promote the departure of the gaseous product(o_(2))from the catalyst surface,preventing isolation between active sites and the reactant(H_(2)o).Here,we successfully reconciled the contradictory wettability requirements for the CRHR and WoHR by creating an alternately hydrophobic *** was achieved through a selectively hydrophobic modification method and a charge-transfer-control ***,the collaboratively promoted CRHR and WoHR led to a significantly enhanced oPCRR with a solar-to-fuel conversion efficiency of 0.186%.Notably,in ethanol production,the catalyst exhibited a 10.64-fold increase in generation rate(271.44μmol g^(-1)h~(-1))and a 4-fold increase in selectivity(55.77%)compared to the benchmark *** innovative approach holds great potential for application in universal overall reactions involving gas participation.

The efficiency of photocatalytic Co_(2) reduction reaction(PCRR)is restricted by the low solubility and mobility of Co_(2) in water,poor Co_(2) adsorption capacity of catalyst,and competition with hydrogen evolution reaction(HER).Recently,hydrophobic modification of the catalyst surface has been proposed as a potential solution to induce the formation of triple-phase contact points(TPCPs)of Co_(2)(gas phase),H_(2) o(liquid phase),and catalysts(solid phase)near the surface of the catalyst,enabling direct delivery of highly concentrated Co_(2) molecules to the active reaction sites,resulting in higher Co_(2) and lower H+surface *** TPCPs thus act as the ideal reaction points with enhanced PCRR and suppressed ***,the initial synthesis of triple-phase photocatalysts tends to possess a lower bulk density of TPCPs due to the simple structure leading to limited active points and Co_(2) adsorption ***,based on constructing a hydrophobic hierarchical porous Tio_(2)(o-HPT)with interconnected macropores and mesopores structure,we have significantly increased the density of TPCPs in a unit volume of the *** with hydrophobic macroporous Tio_(2)(o-MacPT)or mesoporous Tio_(2)(o-MesPT),the o-HPT with increased TPCP density leads to enhanced photoactivity,enabling a high methanol production rate with 1111.5μmol g^(−1) h^(−1) from *** results emphasize the significance of high-density TPCPs design and propose a potential path for developing efficient PCRR systems.

Backg.ound: Benign prostatic hyperplasia (BPH) is the proliferation of the stromal and epithelial cells of the prostate gland, resulting in an increase in its size. This may result in obstruction of the lower urinary tract causing storage and voiding symptoms. Methods: This was a prospective cross-sectional study from August 2020 to July 2021, to evaluate the characteristic of patients presenting to the Tamale Teaching Hospital with lower urinary tract symptoms secondary to BPH. Results: The median age at presentation with LUTS secondary to BPH is 68.88 ± 11.10 years with an average prostate volume of 70 g. The average time of presentation to the hospital is 5 months, mostly with moderate to severe symptoms. Correlation between Prostate volume (PV) and age yielded a positive relationship;however, this was not statistically significant, (r = 0.028, p-value = 0.747). There was a significant positive relationship between PV and the IPSS score, (r = 0.334, p-value Conclusion: our patients with symptomatic BPH present at age 60 years and above, with nearly all of them presenting with moderate to severe LUTS.
