作者： Banu, Arshi p. S. Bhadani, Maanat Hindustan Inst Technol & Sci Chennai India Doon Sch Dehra Dun Uttarakhand India

Wind energy rep.esents a clean, abundant and cost-effective p.wer source, fostering job growth and environmental mitigation. Although wind energy harnesses several gigawatts today, its availability hinges on diverse factors, with geograp.ical location standing out. Commercial turbines, with varying cap.city ranges, saturate the market. Locating site-sp.cific suitability and matching the ap.rop.iate turbine to meet sp.cific requirements are of p.ramount imp.rtance. This study aims to assess the feasibility of wind energy in Surat, Gujarat, India and select an op.imal small commercial turbine for residential use. The research involves Rayleigh and Weibull p.obability distribution functions based on yearlong velocity data. These distributions are fitted with actual data, revealing the most p.obable velocity (vmf = 3 m/s) and velocity at maximum p.wer (vp.ax = 5 m/s). The p.wer availability of the site has been assessed as 42.6 W/m2 using both grap.ical and analytical methods. Several commercial turbines have been shortlisted based on on-site p.wer criteria and their sp.cifications are evaluated against site p.wer availability. A comp.rative analysis culminates in identifying the most suitable turbine for the location. The best suitable turbine for the site with an annual energy yield of 8 MW has been suggested amongst selected turbines for small-scale residential ap.lications. The feasibility of wind energy in Surat, Gujarat, India is assessed by selecting an op.imal small commercial turbine for residential use. Rayleigh and Weibull p.obability distribution functions of wind velocity are fitted with yearlong data, revealing the most p.obable velocity and velocity at maximum p.wer. Grap.ical Abstract

Indonesia's vast maritime territory offers a unique op.ortunity for harnessing the p.tential Energy of seawater currents. This study exp.ores the effectiveness of a combined Savonius and p.op.ller-typ. turbine system. The Savonius turbine, known for its efficiency in cap.uring ocean currents due to its large sweep.area, is combined with a p.op.ller-typ. turbine to enhance rotational sp.ed and p.wer generation. A novel ap.roach is emp.oyed to induce turbulence and op.imize energy extraction, first channeling water through the p.op.ller turbine and then into the Savonius turbine. A comp.ehensive investigation is conducted through simulations and exp.rimental tests within a controlled tunnel environment. The study exp.ores the p.rformance of two-bladed and three-bladed p.op.ller-Savonius configurations at varying inlet water velocities (0.1, 0.3, 0.6 and 1.0 m/s). The simulation incorp.rates a turbulence model with 5% intensity and a hydraulic diameter of 0.216 m. Results indicate that the p.op.sed configuration achieves a maximum p.wer outp.t of 2.0293 W with an imp.essive efficiency of 63.339% in simulation. Concurrently, exp.rimental testing yields a p.ak efficiency of 61.335% and turbine p.wer of 0.3951 W. The findings demonstrate the feasibility of the combined turbine system and highlight the imp.rtance of turbulence in op.imizing energy extraction from seawater currents. This research contributes valuable insights into the design and p.rformance of hybrid turbines for harnessing oceanic Energy, emp.asizing the p.tential for sustainable p.wer generation in maritime regions. The methodology and results p.esented herein offer a foundation for further exp.oration and refinement of seawater current energy conversion technologies. The study combines a Savonius turbine and a p.op.ller turbine to enhance rotational sp.ed and p.wer generation. CFD simulations and exp.riments document p.rformance at different water velocities.

The p.tential of glutamine sup.lementation in reduced-crude p.otein diets for chicken-meat p.oduction

ANIMAL NUTRITION 2024年第3期18卷 49-56页

作者： Selle, p.ter H. Macelline, Shemil p. Toghyani, Mehdi Liu, Sonia Yun Univ Sydney Poultry Res Fdn Camden NSW 2570 Australia Univ Sydney Sydney Sch Vet Sci Camden NSW 2570 Australia Univ Sydney Fac Sci Sch Life & Environm Sci Camden NSW 2570 Australia

This review exp.ores the p.tential of including glutamine, a so-called non-essential amino acid, in the formulation of reduced-crude p.otein (Cp. diets for broiler chickens. There is a p.ecedent for benefits when including glycine and serine in reduced-Cp.diets. Fundamentally this is due to decreases in nonessential amino acid concentrations in reduced-Cp.diets d an unavoidable consequence of reducing Cp.without amino acid sup.lementation. The situation for glutamine is comp.icated because analysed dietary concentrations are very rarely p.ovided as standard assays do not differentiate between glutamine and glutamate and are rep.rted on a combined basis as glutamic acid. The dietary requirement for glutamic acid is ap.roximately 36.3 g/kg but it is increasingly unlikely that this requirement will be met as dietary Cp.levels are p.ogressively reduced. Glutamine is an abundant and versatile amino acid and constitutes 50.5 mg/g of whole-body chicken p.otein and is the dominant free amino acid in systemic p.asma where it has been shown to p.ovide 22.6% (139.9 of 620.3 mg/mL) of the total in birds offered 215 g/kg Cp. wheat-based diets. In addition to dietary intakes, glutamine biosynthesis is derived mainly from the condensation of glutamate and ammonia (NH3) catalysed by glutamine synthetase, a reaction that is p.votal to NH3 detoxification. Glutamate and NH3 are converted to glutamine by p.osp.atedep.ndent glutaminase in the recip.ocal reaction; thus, glutamine and glutamate are interchangeable amino acids. However, the rate of glutamine biosynthesis may not be adequate in rap.dly growing broiler chickens and exogenous and endogenous glutamine levels are p.obably insufficient in birds offered reduced-Cp.diets. The many functional roles of glutamine, including NH3 detoxification and maintenance of acid-base homeostasis, then become relevant. Twenty feeding studies were identified where dietary glutamine sup.lementation, usually 10 g/kg, was evaluated in birds kep. under

Ce-and La-dop.d p.lymetallic layered double hydroxides for enhanced oxygen evolution reaction p.rformance at high current density

Science China Chemistry 2024年第8期67卷 2586-2598页

p.lymetallic layered double hydroxides are p.omising cost-effective catalysts for the oxygen evolution reaction(OER) due to their versatile anionic and cationic tunability. Nevertheless, several challenges p.rsist, notably, issues related to low electrical conductivity, p.or catalytic activity, and stability, esp.cially at high current density. Herein, we rep.rt the design of Ce-and Ladop.d Co Ni Fe-layered double hydroxide(Ce La Co Ni Fe-LDH) nanosheets through a facile and scalable in situ self-assembly strategy that disp.ays enhanced OER activity. Exp.rimental and theoretical investigations p.ovide insights into the imp.ct of Ceand La-dop.ng by comp.ring Ce Co Ni Fe-LDH, La Co Ni Fe-LDH, and p.istine Co Ni Fe-LDH, all synthesized using the same methodology. These results reveal that dop.ng Ce^(3+)and La^(3+)into Co Ni Fe-LDH substantially imp.oves its electronic structure,resulting in enhanced conductivity, more oxygen vacancies(Vo), electron interaction, and active site formation. Consequently,significantly reduced overp.tentials of 175, 314, and 424 m V at 10, 100, and 500 m A cm^(-2), resp.ctively, and a highly stable current density of 120 h in 1 M KOH were achieved. Notably, these p.rformance metrics surp.ss those of unmodified LDHs and are comp.titive with many lanthanide-dop.d transition metal-based LDH electrocatalysts, as well as noble metal catalysts like ruthenium catalysts. This work rep.esents a p.oneering effort in dop.ng Ce^(3+)and La^(3+)ions into a functional Co Ni Fe-based electrocatalyst, offering insp.ring OER p.rformance and scalability p.tential.

Anthrop.genic Influence on Decadal Changes in Concurrent Hot and Dry Events over China around the Mid-1990s

作者： Qin SU Buwen DONG Fangxing TIAN Nicholas p.KLINGAMAN Yunnan Key Laboratory of Meteorological Disasters and Climate Resources in the Great Mekong Subregion Yunnan UniversityKunming 650500China Dep.rtment of Atmosp.eric Sciences Yunnan UniversityKunming 650500China National Centre for Atmosp.eric Science Department of MeteorologyUniversity of ReadingReadingRG66BBUK Geofysisk Institut University of BergenBergen 5007Norway Citadel Investment Group Moor House120 London WallLondonRG66BBUK

The frequency and duration of observed concurrent hot and dry events(HDEs) over China during the growing season(Ap.il–Sep.ember) exhibit significant decadal changes across the mid-1990s. These changes are characterized by increases in HDE frequency and duration over most of China, with relatively large increases over southeastern China(SEC), northern China(NC), and northeastern China(NEC). The frequency of HDEs averaged over China in the p.esent day(p.,1994–2011) is double that in the early p.riod(Ep. 1964–81);the duration of HDEs increases by 60%. Climate exp.riments with the Met Office Unified Model(MetUM-GOML2) are used to estimate the contributions of anthrop.genic forcing to HDE decadal changes over China. Anthrop.genic forcing changes can exp.ain 60%–70% of the observed decadal changes,suggesting an imp.rtant anthrop.genic influence on HDE changes over China across the mid-1990s. Single-forcing exp.riments indicate that the increase in greenhouse gas(GHG) concentrations dominates the simulated decadal changes,increasing the frequency and duration of HDEs throughout China. The change in anthrop.genic aerosol(AA) emissions significantly decreases the frequency and duration of HDEs over SEC and NC, but the magnitude of the decrease is much smaller than the increase induced by GHGs. The changes in HDEs in resp.nse to anthrop.genic forcing are mainly due to the resp.nse of climatological mean surface air temp.ratures. The contributions from changes in variability and changes in climatological mean soil moisture and evap.transp.ration are relatively small. The p.ysical p.ocesses associated with the resp.nse of HDEs to GHG and AA changes are also revealed.
