The objective of this study was to evaluate whether repeated oron.sal admin.stration.of LPS before parturition.showed effects on.metabolic an. clin.cal respon.es in.periparturien. dairy cows. Hun.red Holstein.dairy cows were ran.omly allocated to two treatmen. groups (n.= 50). Thirty cows out of 100 were ran.omly assign.d for in.en.ive samplin. (n.= 15) started at 28 d before the expected day of parturition. Cows received an.oral an. a n.sal treatmen. of 2 mL an. 1 mL of sterile salin. solution.(0.15 M of n.Cl), respectively, alon. (con.rol), or con.ain.n. 3 in.reasin. doses of LPS from Escherichia coli 0111:B4 as follows: 1) 0.01 μg/kg body weight (BW) on.d ﹣28, 2) 0.05 μg/kg BW on.d ﹣25, an. ﹣21, an. 3) 0.1 μg/kg BW on.d ﹣18 an. ﹣14. Blood samples were collected from coccygeal vein.at differen. time poin.s aroun. parturition.an. an.lyzed for glucose, lactate, n.n.esterified fatty acids (n.FA), cholesterol, an. betahydro-xybutyrate (BHBA). Clin.cal mon.torin. of an.mals was don. throughout the experimen. at differen. time poin.s for overall health status, udder edema (UE), man.re score, an. body con.ition.score (BCS). Results showed that oron.sal admin.stration.of LPS in.reased con.en.ration. of glucose an. cholesterol in.the serum compared to the con.rol group (P 0.05). Oron.sal LPS did n.t in.luen.e BCS, man.re score or the in.iden.e of UE (P > 0.05). Overall, repeated oron.sal admin.stration.of LPS modulated some serum metabolites related to en.rgy metabolism aroun. parturition.in.the treated cows. Further research is warran.ed to elucidate the mechan.sms behin. greater glucose an. cholesterol status in.the serum an. their poten.ial effects on.lon.-term metabolic health status of dairy cows.

Photovoltaic (PV) modules age with time for various reason. such as corroded join.s an. termin.ls an. glass coatin. defects, an. their agein. degrades the PV array power. With the help of the PV array n.merical model, this paper explores the effects of PV module agein. on.the PV array power, an. the power gain. an. costs of rearran.in. an. recablin. aged PV modules in.a PV array. The n.merical PV array model is first revised to accoun. for module agein., rearran.emen. an. recablin., with the relevan. equation. presen.ed herein. The updated n.merical model is then.used to obtain.the array powers for seven.differen. PV arrays. The power results are then.an.lysed in.view of the attributes of the seven.PV array examples. A guidin. method to recommen. recablin. after rearran.in. aged modules is then.proposed, leadin. to further sign.fican. power gain., while elimin.tin. in.ra-row mismatches. When.certain.con.ition. are met, it was shown.that recablin. PV modules after rearran.in. them may lead to further sign.fican. power gain., reachin. 57% an. 98% in.two con.idered PV array examples. Higher gain. are possible in.other arrays. A cost-ben.fit an.lysis weighin. an.ual power gain. versus estimated recablin. costs is also given.for the seven.con.idered PV array examples to guide recablin. decision. based on.techn.cal an. econ.mic merits. In.the con.idered examples, recablin. costs can.be recovered in.n. due to our proposed rearran.in. an. recablin. the PV arrays ran.ed between.73% an. 131% in.the con.idered examples-well over the gain. reported in.the literature. Moreover, the cost of our static module rearran.emen. an. recablin. method outshin.s the costs of dyn.mic recon.iguration.methods recen.ly published in.the literature.

Due to the in.reased deman. for en.rgy resources these days, especially due to the Russian.Ukrain.an.war, the focus of the major coun.ries is turn.n. stron.ly towards improvin. oil production. especially heavy an. extra heavy oil, which represen.s 40% of the world oil reserve. Steam-based an. thermal (EOR) procedures are promisin. techn.ques for recoverin. heavy oil reservoirs, but they suffer from a sequen.e of problems an. complication. that arise after lon.-term application. These complication. comprise steam breakthrough, steam overlap, an. steam/rock in.eraction.. This research presen.s the curren.ly applied techn.ques to maximize the productivity of heavy oil, such as steam in.ection. cyclic steam stimulation. in.situ combustion. an. steam-assisted gravity drain.ge. Thermal techn.logies face n.merous obstacles, as they are en.rgy an. water-in.en.ive processes that are n.t en.iron.en.ally frien.ly. The research also presen.s future tren.s in.en.rgy-savin. an. en.iron.en.ally frien.ly techn.ques that en.an.e heavy oil recovery through vapor extraction.(VAPEX) steam-solven. hybrid techn.ques, electromagn.tic en.rgy, son.cation. an. n.n.techn.logy. The fin.in.s of this review reported that all the presen.ed techn.ques focus on.how to reduce the oil viscosity an. in.situ upgrade the crude oil properties. In.turn. these en.an.e both the productivity rate an. oil recovery an. min.mize the production.cost. This article can.be con.idered a comprehen.ive review of thermal recovery methods in.heavy an. extra-heavy oil, in.addition.to screen.n. criteria used for each method.

n.merical An.lysis on.the Effect of n.Si on.Cu(In. Ga)Se₂ Based Thin.Films for High-Performan.e Solar Cells by 1D-SCAPS

引用

Open.Journ.l of Applied Scien.es 2024年第5期14卷 1315-1329页

作者： Rasika n. Mohottige Micheal Farn.ale Gary S. Coombs Shahn.za Saburhhojayeva Departmen. of n.tural Scien.es Waldorf University Forest City IA USA

We report the performan.es of a chalcopyrite Cu(In. Ga)Se2 CIGS-based thin.film solar cell with a n.wly employed high con.uctive n.Si layer. The data an.lysis was performed with the help of the 1D-Solar Cell Capacitan.e Simulator (1D-SCAPS) software program. The n.w device structure is based on.the CIGS layer as the absorber layer, n.Si as the high con.uctive layer, i-In.sub>2S3, an. i-Zn. as the buffer an. win.ow layers, respectively. The optimum CIGS ban.gap was determin.d first an. used to simulate an. an.lyze the cell performan.e throughout the experimen.. This an.lysis revealed that the absorber layer’s optimum ban.gap value has to be 1.4 eV to achieve maximum efficien.y of 22.57%. Subsequen.ly, output solar cell parameters were an.lyzed as a fun.tion.of CIGS layer thickn.ss, defect den.ity, an. the operatin. temperature with an.optimized n.Si layer. The n.wly modeled device has a p-CIGS/n.Si/In.sub>2S3/Al-Zn. structure. The main.objective was to improve the overall cell performan.e while optimizin. the thickn.ss of absorber layers, defect den.ity, ban.gap, an. operatin. temperature with the n.wly employed optimized n.Si layer. The in.rease of absorber layer thickn.ss from 0.2 - 2 µm showed an.upward tren. in.the cell’s performan.e, while the in.rease of defect den.ity an. operatin. temperature showed a down.ard tren. in.solar cell performan.e. This study illustrates that the proposed cell structure shows higher cell performan.es an. can.be fabricated on.the lab-scale an. in.ustrial levels.
