Suzuki-Miyaura cross-coupling reaction
Opis:
N,N,O-Tridentate ligands were prepared by the condensation of 1-(Benzothiazole 2-yl) hydrazine with substituted salicyldehydes or different aromatic ketones. New synthesized metal complex are thermally stable and neither air- nor moisture-sensitive. Suzuki–Miyaura cross-coupling reaction is carried out in present of various ligands and palladium salts, Different solvent/water ratio with different Base and studied effects its effect on the performance of the coupling reaction.

Opis:
p-nucleus, (_1^2)H-nucleus, (_1^3)H-nucleus, and (_2^4)He-nucleus inverse reaction cross sections have been determined using the optical model potentials in a wide range of target nuclei started from A=1 to A=232 using several incident particle energies ( E = 2, 8, 10, 20, and 40 MeV). In this work, a large number of optical model available parameters were used to calculate the inverse reaction cross section and compared to investigate the effect of the mass number and incident particle energy on the inverse reaction cross section. All the calculations were performed using MATHLAB programming language.

Opis:
The subsisting methods of unit rate pricing in the construction industry are either determinate on immediate use basis (analytical pricing) or predictive (cost modeling). The literature cited in this paper showed that cost models used in the industry are spurious. Most of the models attempts to respond to whole building cost from inception to completion with a single formula. This paper argues that on the basis of the units of measurement of the various building elements, a holistic cost model for pricing a complete building cost is a near impossibility. Rather as a negation cost model on the basis of each work item is idealized. Accordingly, this paper responded by generating a unit rate cost model for weld mesh reinforcement. This was done by abstracting and decomposing the relevant cost data and using productivity study by time and motion to determine the various outputs for materials and labour. These were subsequently factored to the cost data to derive the unit rate cost. The paper concludes that the model enjoys flexibility of further mathematical treatment should any of the variable be constrained and recommends that other work items should be modeled if the cost of a project must be known and this model should be used to justify contractor’s tender for weld mesh reinforcement bid.
