In this paper. an appr.ximate analytical method to solve the non-linear.differ.ntial equations in an immobilized enzyme film is pr.sented. Analytical expr.ssions for.concentr.tions of substr.te and pr.duct have been der.ved for.all values of dimensionless par.meter. Dimensionless number. that can be used to study the effects of enzyme loading, enzymatic gel thickness, and oxidation/ r.duction kinetics at the electr.de in biosensor.biofuel cell per.or.ance wer. identified. Using the dimensionless number. identified in this paper. and the plots r.pr.senting the effects of these dimensionless number. on concentr.tions and cur.ent in biosensor.biofuel cell ar. discussed.

Ca2＋-dependent oxidation of cytosolic NADPH is mediated by NDB1, which is an exter.al type II NADPHdehydr.genase in the plant mitochondr.al electr.n tr.nspor. chain. Using r.A inter.er.nce, the NDB1 tr.nscr.pt wassuppr.ssed by 80% in Ar.bidopsis thaliana plants, and exter.al Ca2＋-dependent NADPH dehydr.genase activity becameundetectable in isolated mitochondr.a. This was linked to a decr.ased level of NADP＋ in r.settes of the tr.nsgenic ***-gr.wn tr.nsgenic seedlings displayed decr.ased gr.wth specifically on glucose, and r.spir.tor. metabolism of 14C-glucose was incr.ased. On soil, NDBl-suppr.ssing plants had a decr.ased vegetative biomass, but leaf maximumquantum efficiency of photosystem Ⅱ and CO2 assimilation r.tes, as well as total r.spir.tion, wer. similar.to the wild-type. The in vivo alter.ative oxidase activity and capacity wer. also similar.in all genotypes. Metabolic pr.filing r.vealeddecr.ased levels of sugar., citr.c acid cycle inter.ediates, and amino acids in the tr.nsgenic lines. The NDBl-suppr.ssioninduced tr.nscr.ptomic changes associated with pr.tein synthesis and glucosinolate and jasmonate metabolism. Thetr.nscr.ptomic changes also over.apped with changes obser.ed in a mutant lacking ABAINSENSITIVE4 and in A. thalianaover.xpr.ssing str.ss toler.nce genes fr.m r.ce. The r.sults thus indicate that A. thaliana NDB1 modulates NADP（H）r.duction levels, which in tur. affect centr.l metabolism and gr.wth, and inter.ct with defense signaling.

Intr.duction: Pr.cess evaluation of community based pr.jects is integr.l to under.tanding the success or.failur. of health pr.motion inter.entions. Pr.cess evaluation was used to assess the inter.ention str.tegies and r.sour.es in a playgr.up setting aimed at mother. of young childr.n. Methods: Pr.cess evaluation data wer. collected fr.m par.icipants (n = 249) and staff (n = 25) involved in the inter.ention. Data included staff per.pectives on use of the playgr.up as a setting, par.icipants’ views on the feasibility and acceptability of the pr.gr.m str.tegies and r.sour.es, and pr.gr.m r.ach. r.sults: r.sponding par.icipants r.por.ed that the inter.ention was useful (98%) and r.levant for.their.age gr.up (92%), encour.ged them to think about making changes to their.physical activity (95%) and dietar. (98%) behavior., and helped them to make changes to their.physical activity (66%) and dietar. (79%) behavior.. Par.icipants r.por.ed that the most useful inter.ention str.tegies included the pr.gr.m booklet (85%), wor.shops (86%), newsletter. (73%) and SMS (57%). Conclusion: This r.sear.h pr.vides valuable infor.ation on par.icipants’ per.pectives of the pr.gr.m str.tegies, content and over.ll implementation. It pr.vides insight into the feasibility and acceptability of the inter.ention and identifies ar.as for.impr.vement when conducting pr.gr.ms in playgr.up settings. The pr.cess evaluation indicated that playgr.ups ar. a suitable setting for.health pr.motion tar.eting mother. of young childr.n.

A passive fathometer.can be for.ed by two ver.ically separ.ted hydr.phones. The depth can be estimated fr.m the Gr.en’s function between the hydr.phones, which is calculated fr.m the cr.ss-cor.elation between ocean ambient noise fields r.ceived at those two hydr.phones. The per.or.ance of the fathometer.depends on the signal to noise r.tio (SNr. and the r.solution of the noise cr.ss-cor.elation function. In a given envir.nment, impr.ved SNr.and r.solution of the cr.ss-cor.elation function can be achieved thr.ugh longer.obser.ations, mor. obser.ation points, or.incr.asing bandwidth. Long time aver.ging has been demonstr.ted, but r.quir.s that the channel be stationar. over.the aver.ging time. Hydr.phone ar.ays ar. commonly used, but r.sult in incr.ased cost and complexity. r.cent wor. shows that the SNr.and r.solution of the cor.elation function can also be impr.ved by the use of the lar.e bandwidth noise fields. This paper.shows that the non-sur.ace biological noise gener.ted by mar.ne animals, such as shr.mp, is one of the major.issues in the per.or.ance of such a br.adband passive fathometer.oper.ting in shallow water. This noise tends to occur.at higher.fr.quencies. Fr.quencies at which significant non-sur.ace biological noise is pr.sent cannot be used to impr.ve fathometer.per.or.ance. Consequently, the upper.limit of fr.quencies that can be used in a passive fathometer.is limited by the lower.limit of the bandwidth occupied by the biological noise.

An analytical theor. for.calculating per.ur.ations of the or.ital elements of a satellite due to J2 to accur.cy up to four.h power.in eccentr.city is developed. It is obser.ed that ther. is significant impr.vement in all the or.ital elements with the pr.sent theor. over.second-or.er.theor.. The theor. is used for.computing the mean or.ital elements, which ar. found to be mor. accur.te than pr.vided by Bhatnagar.and taqvi’s theor. (up to second power.in eccentr.city). Mean elements have a lar.e number.of pr.ctical applications.

UV-B r.diation has been widely documented as a str.ssor.for.plants that can cause decr.ased biomass, r.duction in photosynthesis, and oxidative str.ss. Tr.gonelline is a secondar. metabolite that is biosynthesized in some plants in r.sponse to abiotic str.ss such as UV-B ir.adiation. The objectives of this study wer. to examine biochemical str.ss r.sponses for.peanut plants (Ar.chis hypogaea L.) of four.differ.nt genotypes (Spanish, Valencia, Vir.inia, and r.nner. after.exposur. at var.ous lengths to UV-B r.diation and to examine the alter.tion of tr.gonelline biosynthesis due to the age of the plants. Peanut plants fr.m the genotypes wer. exposed to UV-B r.diation at thr.e exposur. times (60, 120, and 180 min);plants fr.m two gr.wth stages, the flower.ng (r.) and ear.y matur.ty (r.), wer. used. Significant positive cor.elations (r. 0.29-0.74, P≤0.05) wer. found for.tr.gonelline concentr.tions and UV-B exposur. times. With longer.exposur. times of 180 min for.plants at r., tr.gonelline biosynthesis began as ear.y as 10 days after.tr.atment with 154.6 μg·g-1 DW and r.mained or.incr.ased by up to 71.5 μg·g-1 DW (46.3%) thr.ughout the sampling inter.als (10, 20, 30, 40, and 50 days after.tr.atment) to a final value of 226.1 μg·g-1 DW. All four.genotypes at r. exhibited tr.gonelline concentr.tions 47.3% to 52.4% (71.6 to 96.5 μg·g-1 DW) higher.than individuals at r.. Tr.gonelline biosynthesis at r. was significantly (Pr., wher.as tr.gonelline concentr.tions at r. wer. significantly influenced (Pr.exposur. times (120 and 180 min). No statistically significant differ.nce was found in tr.gonelline concentr.tion among the four.differ.nt genotypes. UV-B ir.adiation had the gr.atest effect on plants at r. after.120 and 180 min of exposur., as 15 out of 20 (75%) individuals had significantly higher.(Pr.gonelline concentr.tions.
