Solvent effects of pyridine on the NMR spectra of carboxylic acids. I—study of the acrylic,trans-crotonic and 3-butenoic acids

1975

Proton magnetic resonance spectral parameters of acrylic, trans-crotonic and 3-butenoic acids, their methyl esters and the corresponding alcohols (COOH substituted by CH2OH) have been measured for 5% (w/v) solutions in carbon tetrachloride and in pyridine-d5 at 33·5 °C. The total solvent effect of pyridine on the shifts of the skeleton protons of the acid was found to consist of three different effects independently measured from the reference samples.

Recent Advances of Spin Crossover Research

2004

Thermal spin transition (spin crossover), one of the most fascinating dynamic electronic structure phenomena occurring in coordination compounds of third row transition metal ions, mostly of iron(II), iron(III) and cobalt(II) with critical ligand field strengths competing with the spin pairing energy, has attracted increasing attention by many research groups. One of the reasons is the promising potential for practical applications. In this chapter we intend to cover essential recent work, primarily accomplished within the European research network on "Thermal and Optical Switching of Molecular Spin States (TOSS)". New spin crossover compounds and their thermal spin transition behaviour, al…

Investor Inattention to All-Cash Acquisition Announcements: A Joint Day-Time Analysis in the Spanish Market

2021

Prior studies suggest that investors have limited attention, which determines the speed with which information is incorporated into share prices and, in turn, affects the efficiency of the markets. Unlike other corporate events, the information contained in an acquisition announcement is generally less standard and more complicated to process. Therefore, investor inattention is less likely around this event. In this study we test the existence of investor inattention for a sample of all-cash acquisition announcements of listed and unlisted target firms released by listed Spanish firms from 1998 to 2018. Cash acquisitions allow us to control for the strategic behavior of overvalued companies…

Theoretical demonstration of the potentiality of boron nitride nanotubes to encapsulate anticancer molecule.

2015

Anticancer drug transport is now becoming an important scientific challenge since it would allow localizing the drug release near the tumor cell, avoiding secondary medical effects. We present theoretical results, based on density functional theory and molecular dynamics simulations, which demonstrate the stability of functionalized single (10,10) boron nitride nanotubes (BNNTs) filled with anticancer molecule such as carboplatin (CPT). For this functionalized system we determine the dependence of the adsorption energy on the molecule displacement near the inner BNNTs surface, together with their local morphological and electrical changes and compare the values to the adsorption energy obta…

Objectives: The present naturalistic study aims to investigate the differential effects of the patient’s and the therapist’s attachment representations on the attachment to the therapist as perceived by the patient, and their impact on self-esteem-change through psychotherapy.Methods: Attachment variables of N = 573 patients as well as N = 16 therapists were assessed. Attachment representations were measured for therapists and patients via the Bielefelder Questionnaire for Client Attachment Exploration, the Relationship Specific Attachment to Therapist Scales and the Adult Attachment Interview. The patient’s attachment to therapists was evaluated and patients’ self-esteem was measured via t…

Optical characterization of YCa4O(BO3)3 and Nd:YCa4O(BO3)3 crystals

2007

International audience; We report a complete optical characterization of YCa4O(BO3)3 and Nd:YCa4O(BO3)3 crystals. We studied the relative orientation between the dielectric and the crystallographic frames as a function of the wavelength and performed accurate phase-matching angles measurements for second harmonic generation, using a single crystal cut as a sphere. We also recorded polarized luminescence spectra of Nd:YCOB along the principal axes of the dielectric frame. For both crystals, we measured the gray-tracking and the thermo-optic properties as a function of temperature and wavelength using oriented slabs. Finally, we measured all their dielectric and electro-optic coefficients, as…

Unilateral multicystic dysplastic kidney in infants exposed to antiepileptic drugs during pregnancy

2007

Prenatal exposure to antiepileptic drugs (AEDs) increases the risk of major congenital malformations (MCM) in the fetus. AED-related abnormalities include heart and neural tube defects, cleft palate, and urogenital abnormalities. Among the various congenital anomalies of the kidney and urinary tract (CAKUT), multicystic dysplastic kidney (MCDK) disease is one of the most severe expressions. Although prenatal ultrasound (US) examination has increased the prenatal diagnosis of MCDK, the pathogenesis is still unclear. We report on four cases of MCDK in infants of epileptic women treated with AEDs during pregnancy. From October 2003 to June 2006, we observed four infants with unilateral MCDK bo…

Short stem total hip arthroplasty: Potential explanations for persistent post-surgical thigh pain.

2017

Abstract: Short stem uncemented femoral implants were developed with the aim of preserving proximal bone stock for future revisions, improving biomechanical reconstruction, aiding insertion through smaller incisions and potentially decreasing or limiting the incidence of thigh pain. Despite all the advantages of short stem designs, it remains unclear whether they are able to limit post-surgical thigh pain. In patients with short stem hip arthroplasty and persistent thigh pain, it is of the utmost importance to understand the potential etiologies of this chronic pain for selecting the appropriate treatment strategy. Therefore, this manuscript explores the hypothetical etiologies of persisten…

Network governance arrangements and rural-urban synergy

2021

Increasing attention has been paid to the importance of balanced rural–urban interaction to sustainable regional development. Yet, our knowledge on the elements of network governance for such interaction is scarce. The aim of this paper is to study what kind of network governance arrangements currently exist, how they can be improved, and whether evolutionary governance paths can be identified. We analyse five existing and evolving cases of functioning rural–urban interaction in European Union (EU) member states, using a network governance framework as an analytical lens. We supplement the governance analysis with examining what kind of spatial understanding or combination of di…

Imūnsupresīvās terapijas radītās neiroloģiskās blaknes pacientiem pēc nieru transplantācijas

2017

Mērķis: Neiroloģiskas blaknes dažādām imūnsupresīvām zālem nav daudz pētītas un iespējamo blakņu incidences un smaguma atšķirību identifikācia var palīdzēt optimizēt terapiju, lai palīdzētu uzlabot pacientu dzīves kvalitāti pēc transplatācijas. Šī pētījuma mērķis ir salīdzināt incidenci un smagumu neiroloģiskām blaknēm pacientiem, kuri saņem dažāda veida imūnsupresīvu terapiju pēc nieres pārstādīšanas un izvērtēt blakņu incidenci starp sieviešu un vīriešu dzimumiem. Metodes: Pētījums tika viekts Rīgas Paula Stradiņa Klīniskajā Universitātes Slimnīcā ambulatorajā nieru transplantāciju nodaļā. Pētījuma populācija sastāvēja no pacientiem, kuri vismaz sešus mēnešus pēc nieru transplantācijas sa…
