Dedicated to Professor Heinrich Nöth on the occasion of his 85th birthday The metathesis reaction of strontium diiodide [(thf)5SrI2] with K[N(Ph)iPr] in THF yields [(thf)4Sr{N(Ph)iPr}2] (1). Ligand exchange reactions with 1,2-dimethoxyethane (DME), tetramethylethylenediamine (TMEDA), and pentamethyldiethylenetriamine (PMDETA) allow the isolation of the corresponding adducts [(dme)2Sr{N(Ph)iPr}2...
BACKGROUND AND PURPOSE Intraprocedural rupture (IPR) is a well known complication of intracranial aneurysm treatment. Risks and predictors of IPR and its impact on outcome have not been clearly established. METHODS Potential predictors of IPR were evaluated in patients treated in the Cerebral Aneurysm Rerupture After Treatment (CARAT) study using multivariate logistic regression with stepwise...
We describe a new construction algorithm for the recursive generation of all non-isomorphic IPR fullerenes. Unlike previous algorithms, the new algorithm stays entirely within the class of IPR fullerenes, that is: every IPR fullerene is constructed by expanding a smaller IPR fullerene unless it belongs to a limited class of irreducible IPR fullerenes that can easily be made separately. The clas...
Dioxygen reacts with the gold(I) hydride (IPr)AuH under insertion to give the hydroperoxide (IPr)AuOOH, a long-postulated reaction in gold catalysis and the first demonstration of O2 activation by Au-H in a well-defined system. Subsequent condensation gave the peroxide (IPr)Au-OO-Au(IPr) (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene). The reaction kinetics are reported, as well as the...
BACKGROUND The Swedish National Inpatient Register (IPR), also called the Hospital Discharge Register, is a principal source of data for numerous research projects. The IPR is part of the National Patient Register. The Swedish IPR was launched in 1964 (psychiatric diagnoses from 1973) but complete coverage did not begin until 1987. Currently, more than 99% of all somatic (including surgery) and...
پیش زمینه و هدف: بر طبق مطالعات اخیر، نانوذرات فولرن دارای یک ماهیت روبشی قوی برای رادیکال های آزاد در محیط های زیستی می باشند. ازآنجایی که رادیکال های آزاد اکسیژن (ros) یک مکانیسم پایه ای آسیب مغز در سکته هستند، ما قصد داشتیم اثرات محافظت نورونی نانوذرات فولرن بر روی آسیب های مغزی ناشی از ایسکمی در مدل آزمایشگاهی سکته مغزی را موردمطالعه قرار دهیم. مواد و روش کار: آزمایش در سه گروه موش صحرایی ا...
Synthesis and reactivity of coordinatively unsaturated halocarbonyl molybdenum PNP pincer complexes.
In the present study a series of six-coordinate neutral 16e halocarbonyl Mo(ii) complexes of the type [Mo(PNP(Me)-iPr)(CO)X2] (X = I, Br, Cl), featuring the PNP pincer ligand N,N'-bis(diisopropylphosphino)-N,N'-dimethyl-2,6-diaminopyridine (PNP(Me)-iPr), were prepared and fully characterized. The synthesis of these complexes was accomplished by different methodologies depending on the halide li...
Tässä artikkelissa tehdään katsaus aineettomien oikeuksien eli IPR- (intellectual property rights) aineistoihin erityisesti suomalaisesta ja eurooppalaisesta näkökulmasta. Keskityn patentti-, hyödyllisyysmalli-, tavaramerkki- mallioikeusaineistoihin teollisoikeuksiin jättäen tekijänoikeudet tarkastelun ulkopuolelle. Digitalisaation myötä rekisteriaineistojen laatu saatavuus ovat jatkuvasti lisä...
ipr owners have a right about voluntary transfer but sometimes intellectual property right transfer by force and thus, there are challenge that this article regard for its. ipr shall be devolved to their legitimate heirs after their death unless, owner indicate otherwise in their wills. the heirs have the exclusive right to exercise economic and moral rights, they decide upon publication of the...
Herein, we report on the synthesis, characterization, and reactivity studies of first cyclic C 2 As -diradicaloid {(IPr)CAs} ( 6 ) (IPr = C{N(Dipp)CH} ; Dipp 2,6- i Pr H 3 ). Treatment (IPr)CH 1 with AsCl affords Lewis adduct {(IPr)CH }AsCl Compound undergoes stepwise dehydrochlorination to yield {(IPr)CH}AsCl {(IPr)CAsCl} 5a or [{(IPr)CAs} Cl]OTf 5b Reduction (or magnesium turnings gives as a ...
