The qua.tifica.ion of the pa.tern a.d spa.ia. distribution of soil orga.ic ca.bon （SOC） is funda.enta. to understa.d ma.y ecosystem processes. This study a.med to a.ply ordina.y kriging （OK） to model the spa.ia. distribution of SOC in a.selected pa.t of Za.bia. a.tota. of 100 soil sa.ples were collected from the study a.ea.a.d a.a.yzed for SOC by determining soil oxidiza.le ca.bon using the Wa.kley-Bla.k method. a. a.toma.ed fitting procedure wa. followed when modeling the spa.ia. structure of the SOC da.a.with the exponentia. semiva.iogra.. The results indica.ed tha. the short ra.ge spa.ia. dependence of SOC wa. strong with a.nugget close to zero. The spa.ia. a.tocorrela.ion wa. high to medium with a.nugget to sill ra.io of 0.25. The root mea. squa.e error of the predictions wa. 0.64, which represented 58.18% of the mea. observed da.a.for SOC. It ca. be concluded tha. the genera.ed ma. could serve a. a.proxy for SOC in the region where evidence of spa.ia. structure a.d qua.tita.ive estima.es of uncerta.nty a.e reported. Therefore, the ma.s produced ca. be used a. guides for va.ious uses including optimiza.ion of soil sa.a.ling.

Tinnitus is the perception of a.monotonous sound not present in the environment. Nea.ly 20% of the U.S. popula.ion suffers from tinnitus, a.d tinnitus ha. been reported to be the most preva.ent service-connected disa.ility of a.l U.S. vetera.s （Henry et a.., 2005; Eggermont, 2012; Vetera.s Benefits a.ministra.ion, 2014）. Ma.y types of periphera. injury ha.e been understood to induce tinnitus, including da.a.e to the cochlea.by intense sound or ototoxic medica.ions a.d destruction of the a.ditory nerve by cochlea. a.la.ion or nerve tra.section （Lee a.d God- frey, 2014）. The pa.hophysiologica. mecha.isms by which tin- nitus develops a.e only poorly understood. In order to further cla.ify the pa.hogenesis, a.need ha. been expressed for a.better understa.ding of the reba.a.cing of excita.ory a.d inhibitory signa.ing mecha.isms tha. occur a.ter periphera. injury （Gold a.d Ba.o, 2014）. One of the current, prominent hypotheses of tinnitus development is tha., a.ter being triggered by periphera. injury, tinnitus ma. result from a.ma.a.a.ta.ion of the centra. a.ditory system to this periphera. dysfunction （a.erba.h et a.., 2014）, a.d tha. one of the mecha.isms by which this occurs is a.decrea.e in inhibitory neurotra.smission. The ma.or struc- tures tha. pla. a.role in tra.smitting neura. a.tivity through the a.cending centra. a.ditory system include the cochlea. nucleus a.d superior oliva.y complex of the pons-medulla.region, the inferior colliculus of the midbra.n, the media. genicula.e nude- us of the tha.a.us, a.d the a.ditory cortex.
