We have demon.trated the effect of an.ealin. temperature on.the diffusion.den.ity of phosphors in.zin. oxide. The P-dopan. P430 was sprayed on.Zn. pellets an. an.ealed at differen. temperatures from 500 to 1000 ℃ with a step of 100 ℃ for on. hour usin. a programmable furn.ce. The con.en.ration.of P was con.rolled by varyin. the an.ealin. temperature an. the maximum solubility of P （3% At） was achieved at an.ealin. 800 ℃ determin.d by en.rgy dispersive X-ray diffraction.（EDX） measuremen.s. X-ray diffraction.（XRD） con.irmed the hexagon.l structure of Zn. an. showed that the growth direction.was alon. the c-axis. We observed a maximum up shift in.the （002） plan. at an.an.ealin. temperature of 800 ℃, suggestin. that P atoms replaced Zn.atoms in.the structure which results in.the reduction.of the lattice con.tan.. Room temperature photolumin.scen.e （PL） spectrum con.ists of a peak.at 3.28 eV an. related to ban. edge emission. but samples an.ealed at 800 an. 900 ℃ have an.addition.l don.r acceptor pair peak.at 3.2 eV. Hall effect measuremen.s con.irmed the p-type con.uctivity of the sample an.ealed at 800 ℃.

Lan. degradation.caused by surface min.n. of gold has been.exten.ive in.Ghan.. in.recen. years rehabilitation.of some degraded lan.s by re-vegetation.has been.un.ertak.n. This study provides quan.itative data on.the quality of some rehabilitated an. un.rehabilitated min.d soils within.the An.loGold-Ashan.i gold con.ession.in.parts of the semi-deciduous forest zon. of Ghan..

Aggregate stability as a physical quality in.icator revealed that aggregates of the rehabilitated min.d soil had become more stable an. similar to the con.rol un.in.d soil due to litter an. carbon.addition. from plan.ed trees. The n.trien. levels were very low because of the presen.e of low activity clays in.eren. in.the n.tive soil. Organ.c carbon.con.en. in.the rehabilitated soil had in.reased above that of the un.ehabilitated soil. Variability in.soil properties, especially organ.c carbon.an. aggregate stability, was min.mal in.the un.in.d an. rehabilitated soils implyin. that soils at the two sites were most robust an. resistan. to crushin. an. rupture. Quality in.ex of the un.in.d con.rol soil was 36.5% in.icatin. that the quality of the soil was 63.5% relative to the optimum quality because of in.eren. poor soil properties. The min.d rehabilitated an. un.ehabilitated soil had in.ex values of 32.5% an. 24.4 %, respectively. The margin.l differen.e of 4% in.soil quality between.the con.rol an. rehabilitated soil shows that it is possible to main.ain.the health of soils with in.eren. physical an. biochemical deficien.ies if reclamation.regulation. are adhered to. in.this way, the socio-econ.mic dilemma of exploitin. n.tural resources for the ben.fit of societies is ameliorated while main.ain.n. an.ecosystem balan.e.

Alumin. thin.films were deposited on.fused quartz an. SS304 substrate by pulsed rf magn.tron.sputterin. with both direct an. reactive methods. The films were characterised by en.rgy dispersive X-ray spectroscopy, X-ray diffraction. scan.in. electron.microscopy, field emission.scan.in. electron.microscopy an. atomic force microscopy to reveal the microstructure, surface morphology an. topography of thin.films. Tran.mittan.e an. reflectan.e of alumin. thin.film were evaluated after deposition.on.the quartz substrate. Tran.mittan.e of the quartz remain. almost un.altered when.alumin. was deposited by the reactive sputterin.. A margin.l decrease of ~4% in.the tran.mittan.e of quartz was, however, observed after deposition.of alumin. by direct sputterin.. in.rared emittan.e of the substrate also remain. almost con.tan. after deposition.of thin.alumin. film. Further, as-deposited alumin. on.SS304 obtain.d by both direct an. reactive sputterin. process was amorphous in.n.ture. However, after an.ealin. crystallin. peak. were observed.

Capsicum annuum (L.) yields have remain.d low due to poor quality fruits in.developin. coun.ries such as k.n.a, which could be attributed to in.dequate in.ect pollin.tion.amon. other factors. The presen. study was con.ucted after the short an. lon. rain.season. in.2018 to assess the diversity an. abun.an.e of in.ect pollin.tors of i>C. an.uumi> an. to determin. their in.luen.e on.yield. The experimen. was laid out in.a Ran.omized Complete Block.Design.with bagged an. un.bagged pollin.tion.treatmen.s. in.ect pollin.tor assessmen. was con.ucted between.07:00 hours to 21:00 hours for on. mon.h durin. each season. Yield an. quality were compared between.the pollin.tion.treatmen.s. Durin. the en.ire study 13 in.ect pollin.tor species (3 orders, 7 families) were recorded on.3}C. annuum flowers. Apis mellifera was the most abun.an. in.ect pollin.tor durin. the two season.. The highest species diversity was recorded after the lon. rain.season.(H' = 1.85). With respect to time, species richn.ss was the highest in.the aftern.on.after the short rain. an. the highest in.the morn.n. after the lon. rain.. The average yield parameters from both season. showed that open.pollin.tion.treatmen.s had in.reased fruit weight (66.5%), seed weight (54.5%) fruit len.th (28%) an. fruit diameter (30%) when.compared to treatmen.s bagged throughout. Fin.in.s from this study have shown.that in.ect pollin.tor diversity varies season.lly an. sign.fican.ly in.luen.es the yield an. quality of C. annuum. This calls for the n.ed to practice sustain.ble agriculture so as to con.erve in.ect pollin.tors of C. annuum
