LET S3 G S’ denote the twisted S3 bundle over S’. In this paper we will demonstrate an imbedding of a 2-sphere f:S* 4 S3 G S’ #S* x S* such that twisting S3 g S’ #S’ x S* along f(S*) (Gluck construction) produces a fake manifold M4. In fact M4 coincides with the fake S3 2 S’ #S* x S*‘s of [l] and 123. More specifically, if IV;= M-int(B3 g S’) (a fake B3 z S’ # S* x S*) and Q4 is the Cappell-Sha...

objectives : the aim of this in-vitro experimental study was to assess the effect of application of a desensitizing varnish on the enamel and dentin marginal seal. materials and methods: seventy-two freshly extracted, intact human premolar teeth were divided into four groups (n=18). class v cavities (3mm in length, 2mm in width and 2mm in depth) were prepared on the buccal surface of each tooth...

The demonstration was conducted with aim to introduce new rate of blended fertilizer on maize crop and enhance farmers’ awareness toward practice. Sites host farmers selection were undertaken purposively by researcher jointly agricultural experts the corresponding woreda. carried out five one FTC’s field in each kebele, two plots per farmer’s fields used. Totally, 105 participants participated ...

A field experiment was conducted for two consecutive years 2020-2021 and 2021-2022 on clay loam soil at Agricultural College Farm, Bapatla to study the direct residual effect of integrated use organics inorganics nutrient status under rice-sorghum cropping system. The results revealed that all growth stages rice, highest available nitrogen, phosphorus potassium were recorded with application 10...

X-ray photoelectron spectroscopy was used to investigate the characteristics and evolution of sulfur (S) in mixtures of bituminous coal and sewage sludge (SS) and their chars during isothermal combustion. Five groups of mixtures with SS content of 0%, 10%, 20%, 30% and 100%, were examined at different burn-off ratios (beta) of 0, 30%, 50%, 70% and 100%. The S in the coal mainly exist as the for...

Organic fertilizer applications and subsurface drainage are two important measures for improving coastal saline soil; however, nitrous oxide (N2O) emissions from soil under a combination of these seldom evaluated. In this study, cultivated with sunflowers (Helianthus annuus L.) was employed as an experimental system. Prior to the experiment, soils were buried three different spacings (10 m (S1)...
