The flexibility in.radiotherapy can.be improved if patien.s can.be moved between.an. on. of the departmen.’s medical lin.ar accelerators (LIn.Cs) without the n.ed to chan.e an.thin. in.the patien.’s treatmen. plan. For this to be possible, the dosimetric characteristics of the various accelerators must be the same, or n.arly the same. The purpose of this work is to describe further an. compare measuremen.s an. parameters after the in.tial ven.or-recommen.ed beam matchin. of the five LIn.Cs. Deviation. related to dose calculation. an. to beam matched accelerators may compromise treatmen. accuracy. The safest an. most practical way to en.ure that all accelerators are within.clin.cal acceptable accuracy is to in.lude TPS calculation. in.the LIn.Cs matchin. evaluation. Treatmen. plan.in. system (TPS) was used to create three photon. plan. with differen. field sizes 3 × 3 cm, 10 × 10 cm an. 25 × 25 cm at a depth of 4.5 cm in.Perspex. Calculated TPS plan. were sen. to Mosaiq to be delivered by five LIn.Cs. TPS plan. were compared with five LIn.Cs measuremen.s data usin. Gamma an.lyses of 2% an. 2 mm. The results suggest that for four out of the five LIn.Cs, there was gen.rally good agreemen., less than.a 2% deviation.between.the plan.ed dose distribution.an. the measured dose distribution. However, on. specific LIn.C n.med “Asterix” exhibited a deviation.of 2.121% from the plan.ed dose. The results show that all of the LIn.Cs’ performan.e were within.the acceptable deviation.an. deliverin. radiation.dose con.isten.ly an. accurately.

Rhizobium tropici-derived extracellular polymeric substan.es (EPS) have been.used in.soils to en.an.e soil structures an. mitigate soil erosion.. However, in.ormation.on.their use to improve soil health an. fertility in.icators, an. plan. growth is limited. In.a green.ouse study, we in.estigated their effects on.some soil health, soil fertility in.ices, an. the growth of black-eyed peas (Vign. un.uiculate). Results showed that soils in.ubated with EPS sign.fican.ly in.reased basal soil respiration. soil microbial biomass, perman.an.te oxidizable carbon.(POC), an. poten.ially min.ralizable n.trogen.(PMn.. The EPS shifted microbial population. from bacteria to fun.i an. Gram (−ve) to Gram ( ve) bacteria. However, it had little or n. effects on.soil pH, soil organ.c matter (SOM), an. cation.exchan.e capacity (CEC). The EPS decreased soil moisture loss, in.reased soil aggregate stability, but delayed blacked-eyed peas germin.tion. in.the soils. At 0.1% (w/w) con.en.ration. in.soils, there was in.rease in.plan. root n.dulation. an. vegetative growth. This study was carried out within.40 days of in.ubatin. soils with EPS or growin. the black-eyed peas in.a green.ouse study. The plan. growth parameters were taken.before flowerin. an. fruitin.. Further studies of the effects of in.ubatin. soils with the extracellular polymeric substan.es on.plan. growth. Soil microbial biomass, microbial diversities, an. other soil fertility in.ices are deemed n.cessary.
