Two fast algorithms for static test sequence compaction are proposed for sequential circuits. The algorithms are based on the observation that test sequences traverse through a small set of states, and some states are frequently re-visited throughout the application of a test set. Subse-quences that start and end on the same states may be removed if necessary and suucient conditions are met for...

OBJECTIVES The aim of this study was to evaluate the sealing ability of lateral compaction and tapered single cone gutta-percha techniques in root canals prepared with stainless steel and rotary nickel titanium root canal instruments by fluid filtration method. STUDY DESIGN The root canals were prepared with stainless steel (SS) and nickel titanium (NiTi) instruments. The canals prepared with...

Nitrogen (N) fertilizers are widely used in vegetable production, particularly in leafy vegetables such as sweet basil. Nitrogen fertilizers have high solubility and low efficiency rates and in cropping systems are applied in high amounts that result in different health and environmental problems. Despite their high application, however, the plant’s need of N may not be meet. In this stud...

   Grazing intensity should follow the management roles to prevent the soil compaction. Soil compaction decreases plant root penetration so that at 2 MPa the root extension and above ground biomass will stop. In this research, digital penetrometer was used to assessment the soil compaction level in Sabalan region in Ardabil province caused by livestock. Grazing intensity and distance from villa...

The effect, of varying the proportion of binder starch paste (SP) and the disintegrant sodium starch glycolate (SSG), on the compaction behavior of wet granulated acetaminophen (ACM) formulations using a fully instrumented rotary tablet press, was studied. Wet granulation formulations were prepared using ACM, SP as binder (equal to 2.5%, 5% or 10% starch concentration), SSG as disintegrant (0%,...

The ASAE standardized tool to detect the depth and strength of compaction layers in the field is the cone penetrometer. Since this method is point-to-point, researchers have experimented with on-the-fly alternatives that can be used as, or in combination with, a standard tillage tool. On-the-fly compaction layer sensing also enables adaptive tillage, where the soil is only tilled as deep as nec...

The suitability of the new isomalt grade galenIQ™ 801 for dry granulation and following tableting is evaluated in this study. Isomalt alone, as well as a blend of equal parts with dibasic calcium phosphate, is roll compacted and tableted. Particle size distribution and flowability of the granules and friability and disintegration time of the tablets are determined. Tensile strength of tab...

soil compaction reduces growth of secondary roots, soil aeration and water and mineral uptake by plant, and decreases chlorophyll content as well as root yield and sugar content. hence, the effect of soil compaction on sugar beet yield and sugar content farms determined by penetrometer using 40 plots of 100 m2 in 40 sugar beet field of hamedan, asadabad, malayer and bahar at the depth of 0-80 c...
