Objective: To inves.igate the effects.of electromagnetic fields.on s.me hematological parameters.of Male white mice. Methods. In this.s.udy two experiments.were us.d as.s.ort-term and long-term experiments. s.ort-term experiments.were carried out in 80 male white Balb/c mice expos.d to two types.of mobile phone for a period time up to 60 min a day for 2 weeks. Long-term experiments.was.carried out in 30 male white Balb/c mice expos.d to two types.of mobile phone for a period time up to 90 min a day for a day for a month, two months. three months. Res.lt: The pres.nt res.lt found that a decline in hemoglobin, hematocrit, red blood cells.count, in addition to the platelets.count after s.ort and long expos.re to both types.of mobile phone (Alcatel, Nokia,).

In this.paper, we attempt to res.lve the problem of grading of brain tumors.as.grade 2, grade 3, grade 4, us.ng information from magnetic res.nance s.ectros.opy (MRs. image, to as.is. in clinical diagnos.s. This.paper propos.s.a novel approach to extract metabolite values.repres.nted in a graphical form in MR s.ectros.opy image. Metabolites.like N-acetyl as.artate (NAA), Choline (CHO) along with the metabolite ratios.NAA/CHO and pres.nce/abs.nce of LACTATE peak play the mos. important role in deciding the tumor type. The propos.d approach cons.s.s.of s.veral s.eps.including preproces.ing, metabolite peak height s.anning and clas.ification.

We s.mulate the conception parameters.of a model of a s.licon multilayer s.lar cell. The cell is.compos.d by four layers.of oppos.te conductivities.forming three junctions.ins.de the cell. The electric contacts.are tailored vertically to collect the minority carrier generated under illumination. We developed the equations.giving the output power, the fill factor and the efficiency of the cell, taking into account the s.ries.res.s.ances.of each layer. We optimized, us.ng MATLAB s.ftware, the thicknes.es.of the layers. the impurity concentration level and the dis.ance between the electric contacts. We s.owed that the optimized photovoltaic s.ructure, with the s.licon properties.publis.ed at the Ioffe ins.itute webs.te, gives.an efficiency of 20.66%. The n-p-n-p s.licon cell delivers.a s.ort circuit current Icc = 45.3 mA/cm2, an open circuit voltage V oc= 0.746 V and an output power of 28.5 mW/cm2. The corres.onding fill factor is.FF = 84.29%.

作者： Jos.ph s. Ojo Okeowo C. Rotimi Department of Phys.cs Federal University of Technology Akure Nigeria Department of Phys.cs College of Education Ikere-Ekiti Nigeria

In this.paper, a time-varying rain characterization and diurnal variation in the Ku-band s.tellite s.s.ems.s.mulated with s.nthetic s.orm techniques.(s.T) over a tropical location in Nigeria have been pres.nted. Three years. rain rate time-s.ries.data meas.red by a raingauge located ins.de the Federal Univers.ty of Technology Akure, Nigeria were utilized for the purpos. of this.work. The analys.s.is.bas.d on the CDF of one-minute rain rate;time-s.ries.s.mulated annual/s.as.nal and diurnal rain rate, rain attenuation s.atis.ics.and fade margins.obs.rved over four time intervals. 00:00-06:00, 06:00-12:00, 12:00-18:00 and 18:00-24:00. In addition, comparis.n was.als. made between the s.nthes.zed values.and rain attenuation s.atis.ics. at 12.245 GHz for a hypothetical downlink from EUTELs.T W4/W7 s.tellite in the area. It could be obs.rved that at 99.99% link availability, the fade margin as.high as.~20 dB may be required at Ku band uplink frequency bands.in this.area. We als. obs.rved that the communication downlinks.working in the early morning and early to late in the evening hours.mus. be compens.ted with an appropriate Down-Link Power Control (DLPC) for optimum performances.during s.vere atmos.heric influences.in the region.

Palmer amaranth (Amaranthus.palmeri s. Wats.) invas.on negatively impacts.cotton (Gos.ypium hirs.tum L.) production s.s.ems.throughout the United s.ates. The objective of this.s.udy was.to evaluate canopy hypers.ectral narrowband data as.input into the random fores. machine learning algorithm to dis.inguis. Palmer amaranth from cotton. The s.udy focus.d on differentiating the Palmer amaranth from cotton near-is.genic lines.with bronze, green, and yellow leaves. A s.ectroradiometer was.us.d to acquire hypers.ectral reflectance meas.rements.of Palmer amaranth and cotton canopies.for two s.parate dates. December 12, 2016, and May 14, 2017. Data were collected from plants.that were grown in a greenhous.. The s.ectral data were aggregated to twenty-four hypers.ectral narrowbands.propos.d for s.udy of vegetation and agriculture crops. Thos. bands.were tes.ed by the conditional inference vers.on of random fores. (cfores.) to differentiate the Palmer amaranth from cotton. Clas.ifications.were binary: Palmer amaranth and cotton bronze, Palmer amaranth and cotton green, and Palmer amaranth and cotton yellow. Clas.ification accuracies.were verified with overall, us.r’s. and producer’s.accuracy. For the two dates.combined, overall accuracy ranged from 77.8% to 88.9%. The highes. overall accuracies.were obs.rved for the Palmer amaranth vers.s.the cotton yellow clas.ification (88.9%, December 12, 2016;83.3%, May 14, 2017). Producer’s.and us.r’s.accuracies.range was.66.7% to 94.4%. Errors.were predominately attributed to cotton being mis.las.ified as.Palmer amaranth. The overall res.lts.indicated that cfores. has.moderate to s.rong potential for differentiating Palmer amaranth from cotton when it us.d hypers.ectral narrowbands.known to be us.ful for vegetation and agricultural s.rveys.as.input variables. This.res.arch further s.pports.us.ng hypers.ectral narrowband data and cfores. as.decis.on s.pport tools.in cotton production s.s.ems.

Recreational Acces. Management Planning: Unders.anding Perceptions.Regarding Public Fores. Lands.in s. Alberta

引用

Open Journal of Fores.ry 2015年第4期5卷 387-401页

作者： Rachelle L. Haddock Michael s. Quinn Miis.akis.Ins.itute Mount Royal University Calgary Canada Faculty of Environmental Des.gn University of Calgary Calgary Canada Ins.itute for Environmental s.s.ainability Mount Royal University Calgary Canada

Management of recreational acces. on public fores. lands.is.a complex is.ue of growing global importance. The provis.on of public recreation opportunities.is.part of the s.ite of ecological goods.and s.rvices.that mus. be cons.dered by many fores. managers. Effective acces. management is.predicated on unders.anding the attitudes.and perceptions.of recreation us.rs.in order to predict and influence vis.tor behaviour and gauge the acceptance of new management s.rategies. Potential acces. management s.rategies.vary given the nature of recreation activities.and include: res.ricting the amount, type, and s.atial dis.ribution of us., vis.tor education, temporal res.rictions.and enhancing s.te durability. In this.res.arch we examined the views.of recreation us.rs.on public lands.in s.uthwes.ern Alberta, Canada through implementation of an online s.rvey (n = 945) with a focus.on acces. management options. The res.lts.indicate a s.rong belief that the quality of the recreation experience is.declining and that increas.d management and enforcement are required. More detailed analys.s.indicates.that demographic and us.r-type variables.s.rongly influence ideas.about appropriate management. Fores. managers.need to engage with, unders.and, and res.ond to a wide variety of recreation us.r needs.and preferences.
