Hydrolysis of organ.c phosphorus(P) by soil phosphatases is an.importan. process of P cyclin. in.terrestrial ecosystems, sign.fican.ly affected by n.trogen.n. an./or P fertilization. However, how soil acid phosphatase(ACP) an. alkalin. phosphatase(ALP) activities respon. to n.an./or P fertilization.an. how these respon.es vary with climatic region., ecosystem types, an. fertilization.man.gemen. remain.un.lear. This kn.wledge gap hin.ers our ability to assess P cyclin. an. availability from a global perspective. We performed a meta-an.lysis to evaluate the global pattern. of soil ACP an. ALP activities in.respon.e to n.an./or P addition. We also examin.d how climatic region.(arctic to tropical), ecosystem types(croplan., grasslan., an. forest), an. fertilization.man.gemen.(experimen. duration.an. fertilizer type an. application.rate) affected chan.es in.soil phosphatases after fertilization. It was shown.that n.fertilizer resulted in.10.1% ± 2.9% in.rease in.soil ACP activity but a min.mal effect on.soil ALP activity. In.con.rast, P fertilizer resulted in.7.7% ± 2.6% decrease in.soil ACP activity but a small in.rease in.soil ALP activity. The respon.es of soil ACP an. ALP activities to n.an./or P fertilization.were largely con.isten. across climatic region. but varied with ecosystem types an. fertilization.man.gemen., an. the effects of ecosystem types an. fertilization.man.gemen. were en.yme-depen.en.. Ran.om forest an.lysis iden.ified climate(mean.an.ual precipitation.an. temperature) an. chan.e in.soil pH as the key factors explain.n. variation. in.soil ACP an. ALP activities. Therefore, n.in.ut an. ecosystem types should be explicitly disen.an.led when.assessin. terrestrial P cyclin..

Decipherin. the gen.tic determin.n.s in.olved in.cell wall assembly is a strategic issue for breedin. programs that target both rumin.n. feedin. an. biofuel production. The Arabidopsis thalian. model system has great poten.ials to elucidate the gen.tic determin.n.s in.olved in.cell wall compon.n. biosyn.hesis an. those in.olved in.the regulation.cascades allowin. their coordin.ted assembly. QTL for biomass quality related traits (cell wall con.en., lign.n.con.en., an. cell wall degradability) were mapped in.the three Arabidopsis RIL progen.es Bay0 × Shahdara, Bur0 × Col0, an. Blh1 × Col0. Overall, 40 QTL were detected for these traits, explain.n. up to 33 an. 12% of the observed phen.typic variation.for lign.n.con.en. an. cell wall degradability respectively. Major QTL hotspots were mapped on.chromosome 1 (position.5 Mbp), chromosome 4 (position.1 Mbp), an. chromosome 5 (position.3 Mbp). A putative can.idate gen. set (82 gen.s) was con.idered in.ludin. those previously described as in.olved in.cell wall phen.lic compon.n. biosyn.hesis, their regulation.factors, an. gen.s in.olved in.lign.fied tissue pattern.n.. Colocalisation. observed (accordin. to the referen.e sequen.e of Col0) between.the detected QTL an. these can.idate gen.s did n.t prioritize an. of the three gen. groups (mon.lign.l biosyn.hesis, tran.cription.factors, lign.fied tissue pattern.n.). Colocalization. were thus observed for 57% of mon.lign.l biosyn.hesis related gen.s, 55% of the tran.cription.factors con.idered, an. 66% of gen.s con.idered to be in.olved in.lign.fied tissue pattern.n. an. assembly. Colocalization. were observed for at least on. member of all in.estigated gen. families, except WRKY tran.cription.factors. Colocalization. were also shown.with several miRn. putatively in.olved in.the regulation.of lign.fyin. tissue assembly. Takin. in.o accoun. the QTL shown.in.the Bur0 × Col0 progen., allelic variation. were shown.in.the MYB32, MYB58, MYB75, GRAS SCARECROW, AtC3H14 zin. fin.er, SHI

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.

The possibility of the life origin.in.the stellar systems, located at a distan.e of ~200 pc from the solar system, was in.estigated. The stars, in.the spectrums of which C (carbon., O (oxygen., n.(n.trogen., an. P (phosphorus) are foun., are called Dn.-stars. Based on.stellar abun.an.es a n.w method for searchin. for habitable exoplan.ts has been.developed an. a list of 48 Dn.-stars in.the solar n.ighborhood, on.which life is possible, has been.defin.d. The quota of Dn.-stars is equal 1.3% of the total amoun. of Hypatia Stellar Catalog. On.y three Dn.-stars out of selected 48 stars belon. to the spectral class as our Sun.(G2V). The closest to the solar system is the Dn.-star with the n.mber HIP 15510, which belon.s to the G8V class an. is 6 pc away from the solar system. n.n. Dn.-stars, which have the highest chemical similarity with solar spectrum, were iden.ified. It is iden.ified that on. of these n.n. stars, HIP 24681, has six plan.ts.

Chemical elemen.s in.space can.be syn.hesized by stellar n.clear reactors. Studyin. the dyn.mics of processes occurrin. in.the stars in.roduces a con.ept of the en.emble-averaged stellar reactor. For future in.erstellar mission., the terrestrial an. solar abun.an.es were compared with con.iderable n.mber of stars allocated in.the ~200 pc solar n.ighborhood. Accordin. to the value of the effective temperature, four stellar classes are distin.uished, for which the correlation.coefficien.s an. stan.ard deviation.are calculated. The statemen. about the possibility of tran.ferrin. heavy elemen.s syn.hesized by stars over lon. distan.es in.space has been.completely refuted. There is n. immutability of the distribution.of elemen.s on.n.ighborin. stars an. in.the Solar System. It is shown.that chemical elemen.s are main.y syn.hesized in.ide each stellar reactor. The theory of the buoyan.y of elemen.s is gen.ralized to stars. It has been.suggested that stars overheat due to a shift in.the parameters of n.clear processes occurrin. in.ide stars, which leads to the syn.hesis of heavy elemen.s.
