Crystal structure of a rare trigonal bipyramidal titanium(IV) coordination complex: trichlorido(3,3′-di-tert-butyl-2′-hydroxy-5,5′,6,6′-tetramethyl-1…

2017

The title compound, [Ti(C24H33O2)Cl3(C4H8O)], is a rare example of a trigonal–bipyramidal titanium coordination complex with three chloride and two oxygen donor ligands. The asymmetric unit contains two independent molecules having essentially the same conformation. The molecules feature the titanium(IV) metal cation complexed with three chloride ligands, a tetrahydrofuran molecule, and one oxygen atom from the resolved ligand precursor (R)-(+)-5,5′,6,6′-tetramethyl-3,3′-di-t-butyl-1,1′-biphenyl-2,2′-diol, where the remaining phenolic hydrogen atom engages in intermolecular O—H...Cl hydrogen bonding. In one molecule, the THF ligand is disordered over two orientations with refined site occup…

230Th/U dating of Last Interglacial brain corals from Bonaire (southern Caribbean) using bulk and theca wall material

2016

Abstract We compared the suitability of two skeletal materials of the Atlantic brain coral Diploria strigosa for 230Th/U-dating: the commonly used bulk material comprising all skeletal elements and the denser theca wall material. Eight fossil corals of presumably Last Interglacial age from Bonaire, southern Caribbean Sea, were investigated, and several sub-samples were dated from each coral. For four corals, both the ages and the activity ratios of the bulk material and theca wall agree within uncertainty. Three corals show significantly older ages for their bulk material than for their theca wall material as well as substantially elevated 232Th content and (230Th/238U) ratios. The bulk mat…

Diorganotin(IV) complexes ofD-galacturonic acid: solid-state and solution-phase structural study

2003

Three diorganotin(IV) complexes of D-galacturonic acid (H2GalA; R = Me, n-Bu, Ph), two of which are new derivatives (R = Me, Ph), have been synthesized and their solid-state and solution-phase investigated by IR, Mossbauer, 1H, 13C and 119Sn NMR spectroscopy. The FTIR data suggest that H2GalA, in the dialkyltin derivatives, behaves as a dianionic ligand, coordinating the tin(IV) atom through an ester-type carboxylate and deprotonated alcoholic hydroxo groups, whereas a bridging carboxylate occurs in the diphenyltin(IV) complex. Octahedral and trigonal bipyramidal local geometries on tin(IV) atoms are proposed for dialkyltin(IV)GalA and diphenyltin(IV)GalA complexes respectively on the basis…

Dažu funkciju definēšana, lietojot diferenciālvienādojumus

2022

Darbā ir apūkoti divi paņēmieni funkciju definēšanai: paņēmiens, kas balstās uz teorēmu par lineāra homogēna diferenciālvienādojuma atrisinājuma eksistenci un vienīgumu (Košī uzdevuma atrisinājums) un klasiskais vidusskolas vai matemātiskās analīzes paņēmiens. Darbā tiek aplūkotas sekojošas funkcijas: eksponentfunkcija, hiperboliskais sinuss un kosinuss un trigonometriskais sinuss un kosinuss. Liela uzmanība veltīta šo funkciju svarīgākajām īpašībām un formulu pierādījumiem ar abu paņēmienu palīdzību. Rezultātā jaunais paņēmiens ar diferenciālvienādojumu palīdzību tiek uzskatīts par salīdzinoši viegli uztveramu un izmantojamu, kuru var pielietot zinot tikai vienu teorēmu no diferenciālvienā…

Sensibilidad al trigo y gluten no celiaca. Identificación de la enfermedad y manejo nutricional

2019

La sensibilidad al gluten no celiaca (SGNC) es un trastorno caracterizado por síntomas tanto intestinales como extraintestinales con la ingestión de alimentos que contienen gluten en individuos con un diagnóstico negativo para la enfermedad celiaca (EC) y alergia al trigo/gluten (AG). Los síntomas podrían ser causa de la ingesta no solo del gluten, sino de otros componentes vinculados al trigo como los inhibidores de la amilasa y la tripsina (ATIs) y los carbohidratos de cadena corta (oligosacáridos, disacáridos y monosacáridos) y polioles (FODMAPS). El tratamiento establecido hasta el momento para evitar estos síntomas es la dieta sin gluten (DSG). No se ha definido ningún biomarcador que …

Isolated erythema (cellulitis) of the breast.

2002

Abstract This paper reports nine cases of breast cellulitis in women patients (four cases in pregnancy, four postmenopausal cases following hormone replacement therapy and one case of unilateral breast oedema following a mediastinal lymphoma). Biopsies were obtained from the erythematous area in one pregnant patient, one postmenopausal patient and the patient with breast oedema associated with the mediastinal lymphoma. Histology revealed unspecific dermatitis with extensive perivascular lymphoplasmocellular infiltrates. Histopathological examination of biopsies obtained from the underlying mammary tissue along with the corresponding mammographic data gave no evidence of mastitis or mammary …

Solitary Myofibroma of the Bladder Trigone in a 3-Month-Old Patient: First Case Report

2016

Visceral solitary myofibromas are uncommon in childhood. We report a case of a solitary asymptomatic visceral myofibroma of the bladder trigone occurring in a 3-month-old boy. Once malignancies were ruled out by cystoscopy, radical excision was performed in order to avoid any potential impairment of bladder dynamic. Postoperative course was uneventful and patient was discharged on day 3 after surgery. After 36 months of follow-up, the patient is toilet-trained and remains well; bladder function is normal.

Differential of metric valued Sobolev maps

2020

We introduce a notion of differential of a Sobolev map between metric spaces. The differential is given in the framework of tangent and cotangent modules of metric measure spaces, developed by the first author. We prove that our notion is consistent with Kirchheim's metric differential when the source is a Euclidean space, and with the abstract differential provided by the first author when the target is $\mathbb{R}$.
