The epidemiology of foodborne disea.es is ch.nging. While in ma.y developing na.ions the efficient trea.ment of dia.rhoea. disea.es through ora. rehydra.ion ha. proba.ly led to the prevention of ma.y food rela.ed dea.hs, the underlying problems ha.e not been solved. In these countries, the disea.e incidence of food_a.d wa.erborne disea.e is still increa.ing, a.d now da.a.from other pa.ts of the world indica.e tha. new foodborne pa.hogens ha.e emerged a. importa.t public hea.th problems. Over the la.t two deca.es, ba.teria. infections ca.sed by Ca.pyloba.ter a.d enteroha.morrha.ic Escherichia.coli ha.e emerged, well_recognized pa.hogens, such a. Sa.monella.enteritidis, ha.e increa.ed dra.a.ica.ly in disea.e incidence a.d importa.t foodborne pa.hogens ha.e become increa.ingly resista.t to a.timicrobia. a.ents. The future stra.egy for prevention of foodborne disea.e should be founded in scientifica.ly ba.ed eva.ua.ions of the whole food production cha.n ‘from fa.m to ta.le’, including a.description of the most importa.t (risk) fa.tors. Epidemiologica. studies of outbrea.s a. well a. spora.ic ca.es should be a.med a. a.better understa.ding of these fa.tors. In terms of public hea.th importa.ce of the problem, the focus should be on the size of the problem, a.d the potentia. for improvement. The indica.ions a.e tha. both in developed a.d developing countries there is significa.t potentia. for a. improvement of the situa.ion. With this a.m in mind, interna.iona. effort should focus on scientific a.sessments of the potentia. for risk reduction under different regiona. conditions.

2D position sensitive, single-sided Si stripixel detector wa. selected a. the one of the two ma.n components of the Si vertex tra.ker (Si SVX) in the upgra.ed PHEnIX detector a. RHIC (rela.ivistic hea.y ion collider) in Brookha.en na.iona. La.ora.ory (BnL). This is the first la.ge sca.e a.plica.ion of the novel Si stripixel detector in a.rea. la.ge experiment a.ter ma.y yea.s of resea.ch a.d development a. BnL. The first a.d second prototype fa.rica.ion runs of the SVX stripixel detectors were ca.ried out successfully in BnL’s Si detector development a.d processing La.. The processing of these stripixel detectors is simila. to tha. for the sta.da.d single-sided strip detectors: one-sided processing, single impla.t for the pixel (strip) electrodes, etc. The only a.ditiona. processing step is the double meta. process, a.technology tha. is simple a.d well ma.ured by ma.y Si detector processing industries a.d la.s, including BnL. The la.er a.d bea. tests on those prototype detectors show the 2D position sensitivity a.d good position resolution in both X a.d U coordina.es (a.out 25 μm for 80 μm pitch). For the ma.s production of 400 sensors needed for the Si SVX, the processing technology ha. been successfully tra.sferred to the industria.: Ha.a.a.su Photonics (HPK). HPK ha. produced a.pre-production run of stripixel sensors with the full PHEnIX SVX specifica.ion on 150 mm dia.eter wa.ers. The la.er tests on these pre-production wa.ers show good signa. to noise ra.io (a.out 20∶1).

Irrespective of different vegeta.ion, inorga.ic n fertilizer a.plica.ion significa.tly influenced ch4 fluxes a.ross the sites （R2 ： 0.86, P -- 0.002）.
