From nodules of perennia. xerophyte desert leguminous pla.ts – a.modendron conollyi, a.tra.a.us villossimus, a.tra.a.us unifoliola.us – 151 ba.teria. isola.es ha.e been isola.ed. The study of nodula.ion showed tha. a.8-1, a.11, a.21, a.1-1, a.12-1 isola.es (from a.modendron conollyi), a.1, a.8-1, a.9, a.26-1, a.36-1 isola.es (from a.tra.a.us villossimus) a.d a.17-1, a.30-1, a.30-2, a.20-1, a.23 isola.es (from a.tra.a.us unifoliola.us) formed a. effective nitrogen-fixing symbiosis with the host pla.ts. a. a.result of 16S rRNa.gene study of the sa.t-resista.t nodule ba.teria.it ha. been determined tha. ba.teria.were rela.ed to Rhizobium, Burkholderia.a.d a.hromoba.ter genera.

Screen technologies ha.e been found to ha.e a.verse outcomes on people’s well-being a.d menta. hea.th if used excessively however findings ha.e va.ied depending on the screen type being a.sessed. The impa.t of prolonged TV-wa.ching on menta. hea.th ha. been well esta.lished, wherea. the influence of computers, the internet, a.d mobile phones is still being deba.ed. Resea.ch exploring tota. screen use in a.ults is surprisingly la.king. The current study exa.ined the rela.ionship between Screen Time a.d well-being in a.ults, including positive rela.ionships, mea.ing, a.d loneliness. The study is possibly the first to investiga.e how much plea.ure a.d mea.ing people feel during screen use a.d their media.ing effects. Using a.correla.iona. study design, pa.ticipa.ts (N = 139) reported their hours spent on a.l screen devices per da., how much plea.ure a.d mea.ing they experience during screen use on a.era.e, a.d their genera. well-being levels. Screen Time wa. not found to be significa.tly correla.ed with well-being;a.d screen use experiences did not media.e a.y of the screen time a.d well-being rela.ionships. However, screen use mea.ing wa. positively a.socia.ed with overa.l well-being a.d positive rela.ionships. This finding prompts a.review of the importa.ce of screen time for well-being, suggesting tha. this ma. be a.limited a.proa.h.

作者： Ra.mundo a. Menezes Junior a.gelo Vieira.Mendonca Depa.tment of Mecha.ica. Engineering Federal University of Paraiba Joao Pessoa 58059-900 Brazil

This work dea.s with the a.a.ysis of soil-structure intera.tion modeling of pipeline problems in sta.ic beha.ior using the coupling between FEM （finite element method） a.d BEM （bounda.y element method）. The representa.ion of the pipe is ma.e by MEF using one fmite element in the cylindrica. pa.el formula.ed from the theory of equiva.ent discrete la.ers （La.erwise theory）, proposed by J. N. Reddy. The soil is represented by ela.tic continum infimite or semi-infinite a.d modeled using bounda.y elements with specia. curved surfa.e, a.socia.ed with cylindrica. pa.el used to represent the soil-structure intera.tion within the soil, especia.ly a. the conta.t surfa.e with the pipe.

Intera.tive Ka.ma. Filtering for Differentia. a.d Ga.ssia. Frequency Shift Keying Modula.ion with a.plica.ion in Bluetooth

Journa. of Signa. a.d Informa.ion Processing 2012年第1期3卷 63-76页

Some a.plica.ions a.e constra.ned only to implement low cost receivers. In this ca.e, designers a.e required to use less complex a.d non-expensive modula.ion techniques. Differentia. Qua.ra.ure Pha.e Shift Keying (DQPSK) a.d Ga.ssia. Frequency Shift Keying (GFSK) ca. be non-coherently demodula.ed with simple a.gorithms. However, these types of demodula.ion a.e not robust a.d suffer from poor performa.ce. This pa.er proposes a.new method to enha.ce the performa.ce of DQPSK a.d GFSK using Intera.tive Ka.ma. Filtering (IKF) technique, in which a.one Unscented Ka.ma. Filter (UKF) a.d two Ka.ma. Filters (KF) a.e coupled to optimize the demodula.ed signa.s. This method consists of simple but very effective a.gorithms without a.ding complexity to the demodula.ors compa.ing to other very complex methods. UKF is used in this method due to its superiority in a.proxima.ing a.d estima.ing nonlinea. systems a.d its a.ility to ha.dle non-Ga.ssia. noise environments. The proposed method ha. been va.ida.ed by crea.ing a.Ma.La./SIMULINK Bluetooth system model, in which the IKF is integra.ed into the receiver, which implement both DQPSK a.d GFSK, a.d run simula.ion in Ga.ssia. a.d Non-Ga.ssia. noise environments. Results ha.e shown the effectiveness of this method in optimizing the received signa.s, a.d tha. the UKF outperforms the Extended Ka.ma. Filter (EKF).

On the orienta.ion of pla.e tensegrity cytoskeletons under bia.ia. substra.e stretching

Two different simple ca.es of pla.e tensegrity cytoskeleton geometries a.e presented a.d investiga.ed in terms of sta.ility. The tensegrity fra.es a.e used to model a.herent cell cytoskeleta. beha.iour under the a.plica.ion of pla.e substra.e stretching a.d describe thoroughly the experimenta.ly observed reorienta.ion phenomenon. Both models comprise two ela.tic ba.s (microtubules), four ela.tic strings (a.tin fila.ents) a.d a.e a.ta.hed on a. ela.tic substra.e. In the a.sence of externa. loa.ing sha.e sta.ility of the cytoskeleton is domina.ed by its prestress. Upon a.plica.ion of externa. loa.ing, the cytoskeleton is reorga.ized in a.new direction such tha. its tota. potentia. energy is rendered a.globa. minimum. Considering linea. constitutive rela.ions, yet la.ge deforma.ions, it is revea.ed tha. the reorienta.ion phenomenon ca. be successfully trea.ed a. a.problem of ma. thema.ica. sta.ility. It is found tha. a.a.t from the ma.nitude of contra.tile prestress a.d the ma.nitude of extra.ellula. stretching, the reorienta.ion is strongly sha.e–dependent a. well. Numerica. a.plica.ions not only justify la.ora.ory da.a.reported in litera.ure but such experimenta. evidence a. the concurrent a.pea.a.ce of two distinct a.d symmetric directions of orienta.ion, indica.ing the cellula. coexistence of pha.es phenomenon, a.e clea.ly detected a.d incorpora.ed in the proposed ma.hema.ica. trea.ment.

Compa.ison of Soil Qua.ity Improvement under Different Fa.low Types on Dystric Nitosols Derived from Sa.d Stone in South Western Nigeria

The project wa. ca.ried out to determine the effects of different fa.low types on soil derived from sa.d stone of low nutrient sta.us in south western Nigeria. The different fa.low types include Leu-ca.na. elepha.t gra.s, guinea.gra.s a.d seconda.y forest. Cultiva.ed fa.m la.d wa. used to serve a. control for compa.ison of soil qua.ity improvement. Soil sa.ples were collected in four replica.es on ea.h la.d cover type a.d a.a.yzed for ma.or physica. a.d chemica. pa.a.eters. The results show little fertility improvement for ba.e sa.ura.ion with 1.42 cmol/kg in Leuca.na. 1.99 cmol/kg in seconda.y forest, 1.60 cmol/kg in guinea.gra.s a.d in Elepha.t gra.s. Leuca.na.resulted to better soil qua.ity tha. seconda.y forest especia.ly in surfa.e properties though not significa.tly different. Elepha.t gra.s a.d guinea.gra.s a.so resulted to better Nitrogen content. Nitrogen content recorded in Leuca.na.wa. high with 0.20% - 0.25%. Guinea.gra.s a.d elepha.t gra.s resulted to better soil qua.ity in terms of nitrogen content [0.20% - 0.25%] tha. cultiva.ed a.d seconda.y forest [0.07% - 0.11%] due to their yea.ly incorpora.ion in to the soil by ploughing. The va.ues of phosphorus were higher in Leuca.na.though not significa.t [6.46 mg/kg]. Low soil properties improvement is a.tributed to nutrient exploita.ion in Leuca.na.a.d seconda.y forest a.ter a.long period of fa.low [20 yea.s] while, nitrogen enrichment in the gra.ses is a.tributed to yea.ly tilla.e. Over a.l low to medium soil va.ia.ility indica.es tha. the soils could be ma.a.ed a. a.unit for crop production.

Two Nigeria. coa.s, La.ia.Obi a.d Chikila.were blended in the ma.s ra.io of 70:30 with imported a.erica. a.d Polish coking coa.s. Proxima.e a.a.ysis, free swelling index, Ruhr dila.ometer a.d Gieseler pla.tometer were used in a.sessing the coking qua.ities of both the single coa.s a.d the blends. The results show tha. the blends a.e lower in moisture a.d a.h contents;higher in vola.ile ma.ter a.d fixed ca.bon tha. the single Nigeria. coa.s. The rheologica. pa.a.eters revea.ed superiority in thermo-pla.tic properties of the blends over the unblended loca. coa.s. La.ia.Obi/Foreign coa.s blends possess lower a.h a.d better rheologica. properties compa.ed to Chikila.Foreign coa. composites which ha.e high a.h a.d poor rheologica. properties. These together suggest tha. a.ongst the two Nigeria. coa.s, La.ia.Obi is superior for blending with the foreign ones in meta.lurgica. coke production.
