background: coordination is a critical factor in successful organization and appropriate response to disasters. in this regard, a centralized coordination mechanism is the first step towards an effective, efficient, and sustainable response in order to be ensured of the short- and long-term recovery. thus, this study aimed to identify and prioritize the barriers and facilitators of coordination...

Series of chiral palladium(II) allyl and cinnamyl complexes bearing a C1-symmetric N-heterocyclic carbenes were synthesized from achiral precursors. The chirality theses results the formation carbene-palladium bond which restricts rotation dissymmetric N-aryl substituents NHC thus creates an axis chirality. Chiral HPLC at preparative scale enabled resolution racemic provided straightforward acc...

The development of coastal adaptation pathways along sandy barrier-island coasts requires an understanding multi-decadal barrier morphodynamics in response to forcings such as sea-level rise, sediment fluxes, and storminess. Long- cross-shore sand exchanges among barrier-system compartments (shorefaces, beaches, dunes, tidal inlets, backbarrier lagoons) between adjacent islands can play a funda...

introduction recently, employment of rotary tillers has been expanded in gardens and small farms, especially in the northern of iran. however using the l-shaped blades in the conventional rotary tillers have some problems such as severe vibration problems, weeds stucking around the blades, forming the plow pan and lower performance due to the less powers of such small rototillers. therefore in ...

Abstract We have studied the strength of Bardeen–Cooper–Schrieffer (BCS) pairing force, used as a residual interaction to relativistic mean-field approach, reproduce height inner fission barriers for actinide nuclei. It was found that increasing by about $13\%$ makes reproduction better over wide range This result verified using moment inertia rotational energy, which introduced avoid and odd-m...

A complete quantum study for the state-to-state Li + HF(v,j,m) LiF(v0,j0,O0) + H reactive collisions has been performed using a wave packet method, for different initial rotational states and helicity states of the reactants. The state-to-state differential cross section has been simulated, and the polarization of products extracted. It is found that the reactivity is enhanced for nearly collin...

this field study was conducted  to investigate barriers to applying principles of management in wards of tehran university on medical science hospitals: head nurses' viewpoints .75 hednurses who  were working  in selected hospitals affiliated to tehran university of medical sciences. the data collection tool was a questionnaire that  it,s validity and reliability was obtained using content...

A complete quantum study for the state-to-state Li + HF(v,j,m) → LiF(v',j',Ω') + H reactive collisions has been performed using a wave packet method, for different initial rotational states and helicity states of the reactants. The state-to-state differential cross section has been simulated, and the polarization of products extracted. It is found that the reactivity is enhanced for nearly coll...

third molar eruption is an unpredictable event. occasionally, mandibular third molars undergo angular changes in young adults. this rotational drift is of unknown etiology, is not predictable and may facilitate the eruption or may make the impaction worse. a rare case is presented with severe rotational drift of a mesioangularly impacted mandibular third molar.
