Precision Measurement of the Beam-Normal Single-Spin Asymmetry in Forward-Angle Elastic Electron-Proton Scattering.

A beam-normal single-spin asymmetry generated in the scattering of transversely polarized electrons from unpolarized nucleons is an observable related to the imaginary part of the two-photon exchange process. We report a 2% precision measurement of the beam-normal single-spin asymmetry in elastic electron-proton scattering with a mean scattering angle of θ_{lab}=7.9° and a mean energy of 1.

Umbilical arterial catheter insertion length: in quest of a universal formula.

Objective: The study was aimed at comparing the accuracy in length of insertion of umbilical arterial catheter in all new born groups stratified according to weight, by using two different methods, that is, Wright et al./Case (Group I): (4 × Body wt (BW) (kg)) +7; Shukla et al./Control (Group II): (3 × BW (kg)) +9.

Transported neonates by a specialist team - how STABLE are they.

The study was designed to compare the biochemical characteristics of neonates transported by qualified transport team, before and after stabilization, interventions required and setbacks during these transports. Prospective cohort study of all neonatal transports during a period of 13 months from various maternity and pediatric centers was conducted; 151 babies who fulfilled the criteria were included in the study. 58% of babies < 32 wks were hypothermic, 21% of the total babies were hypotensive and a total of 25% of the babies were hypoxic at the referral hospital.

The importance, design and modeling of biodegradable complexants. An extension of the structure-soft character relations.

Complexing Chem. or chelating agents are used in plant cultivation to avail of different phytobiologically useful macro- and microelements. The great majority of the traditional chelators (e.

Soft ligands--biodegradable complexants in plant cultivation and environmental protection.

In this paper, the place and role of biodegradable complexants in light of modern plant cultivation criteria is discussed. From this point of view, micro- and macroelement (metal) chelators play a remarkable role. They are widely used in a variety of consumer products and processes, especially in agriculture.
