The activity of the Kazan governorate nobility self-government in the middle of the 19th - early 20th century

© the author(s). The importance of the research of the Kazan Governorate nobility self-government activity in the middle of the 19th - early 20th centuries is determined by the fact that the study of this issue gives the opportunity to define the scenarios of keeping the power in the hands of the nobility, as well as the domestic needs of the nobility who represented multifunctional institutions handling both the problems of their social class and the local administration issues. This research is supported by the system approach based upon the study of noble institutions as an integral whole, and all aspects of its activity are geared to the interests of the nobility. The article highlights the study of the Kazan Governorate noble institutions as the bodies of the social class self-government. The authors investigated the interaction with the local government, and the influence on the government policy during the petition campaign and by means of the meetings of the governorate noble society representatives. The activity of the noble institutions shows their role in the formation of the civil society. The practical value of the research is that its conceptual issues and conclusions may be used in the preparation of the summarizing and special works on the history of Russia and Tatarstan. These materials are of research and practical interest within the study of social, political and economic life of the Russian Empire and Kazan Governorate

I. A. Bunin’s Reception in the Literary Cricicism of the Russian Abroad

Благодарности: Смирновой Альфии Исламовне.Acknowledgments: Alfiya I. Smirnova.В статье анализируется восприятие творчества И. А. Бунина литературной критикой русского зарубежья: как хранителя традиций русской литературы, «русского изгнанника», воссоздавшего в своих произведениях рухнувший уклад дореволюционной России; проявление реалистических и модернистских традиций; темы смерти и памяти в зрелом творчестве.The article analyzes I. A. Bunin’s perception by the literary criticism of the Russian abroad. There are distinguished the main aspects of understanding the writer’s prose: Bunin as a Russian literature tradition keeper, as a “Russian exile”, who in his works tried to reflect the collapsed way of pre-revolutionary Russia; realistic and modernist traditions in Bunin’s works; the key topics of death and memory in Bunin’s last works

Proposal for a Listening Comprehension Oriented Classroom -With focus on interpretation practise-

© 2016 American Chemical Society.Interaction of 4,5-dimethyl-2-(2-oxo-1,2-diphenyl)ethoxy-1,3,2-dioxaphospholane, bearing a carboxyl group in the γ-position with respect to the phosphorus atom and obtained from d,l-butanediol, with hexafluoroacetone (CCl4, -40 °C) leads to the simultaneous formation of regio- and stereoisomeric cage-like phosphoranes with phosphorus-carbon and phosphorus-oxygen bonds with a high stereoselectivity (>95%), whose structure was determined by 1D and 2D NMR spectroscopy and XRD. When stored as a solution in dichloromethane for one month, the PCO-isomer rearranges into the thermodynamically more stable POC-isomer of the cage-like phosphorane. Mild hydrolysis of the PCO/POC-isomers proceeds with a high chemoselectivity and leads to the formation of P(IV)-dioxaphospholane derivatives. Acidic hydrolysis of the POC-isomer leads to the formation of an oxirane derivative with an unexpectedly high stereoselectivity (>95%). DFT calculations (using the PBE functional) allowed us to obtain structures and energies of the initial phospholane, reaction products (PCO/POC-isomers), and an intermediate P(V)-oxaphosphirane

Upper Limit on the Magnetic Dipole Contribution to the 5p-8p Transition in Rb by Use of Ultracold Atom Spectroscopy

We report on hyperfine-resolved spectroscopic measurements of the electric-dipole forbidden 5$p_{3/2} \to 8p_{1/2}$ transition in a sample of ultracold $^{87}$Rb atoms. The hyperfine selection rules enable the weak magnetic-dipole (M1) contribution to the transition strength to be distinguished from the much stronger electric-quadrupole (E2) contribution. An upper limit on the M1 transition strength is determined that is about 50 times smaller than an earlier experimental determination. We also calculate the expected value of the M1 matrix element and find that it is less than the upper limit extracted from the experiment.Comment: 7 pages, 4 figures, 3 table

Cauchy projectors on non-smooth and non-rectifiable curves

Let f (t) be defined on a closed Jordan curve Γ that divides the complex plane on two domains D + , D − , ∞ ∈ D − . Assume that it is representable as a difference f (t) = F + (t) − F − (t), t ∈ Γ, where F ± (t) are limits of a holomorphic in C \ Γ function F (z) for D ± 3 z → t ∈ Γ, F (∞) = 0. The mappings f → F ± are called Cauchy projectors. Let H ν (Γ) be the space of functions satisfying on Γ the Hölder condition with exponent ν ∈ (0,1]. It is well known that on any smooth (or piecewise-smooth) curve Γ the Cauchy projectors map H ν (Γ) onto itself for any ν ∈ (0, 1), but for essentially non-smooth curves this proposition is not valid. We will show that even for non-rectifiable curves the Cauchy projectors continuously map the intersection of all spaces H ν (Γ), 0 < ν < 1 (considered as countably-normed Frechet space) onto itself

Detection of sulfate surface-active substances via fluorescent response using new amphiphilic thiacalix[4]arenes bearing cationic headgroups with Eosin Y dye

© 2016 Elsevier B.V.New ammonium-containing derivatives of p-tert-butylthiacalix[4]arene in 1,3-alternate stereoisomeric form were synthesized via copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction of corresponding azides with N-propargyl-N,N,N-triethylammonium bromide. Critical aggregation concentration (CAC) of new amphiphilic thiacalixarenes 1-3 (with butyl, octyl and tetradecyl substituents) determined by pyrene micellization method are 91, 59 and 33 μM, respectively. According to DLS data the diameter of these aggregates is around 130 nm. Anionic dye Eosin Y (EY) forms the associates with positive charged thiacalixarenes 1-3, shifts CAC to the low concentration region (2 μM) and decreases nanoaggregates size up to 90 nm. Thiacalixarene/EY associates were investigated as fluorescent probe for the determination of different surface active substances (SAS) in the solution. It was found that only sodium dodecyl sulfate (SDS) and sodium laureth sulfate (SLES) causes EY release, while other anionic, cationic and zwitterionic SAS form only mixed aggregates. Fluorescent response of thiacalixarene/EY associates is considerable from 3.5 μM concentration of SDS

Tracheobronchial injuries in blunt thoracic trauma

Catedra Chirurgie nr.1 ,,Nicolae Anestiadi’’, Catedra Chirurgie nr.4, USMF ,,Nicolae Testemiţanu’’, Secția Chirurgie Toracică, Departament Clinic Chirurgie IMU, Chișinău, Republica Moldova, Conferința stiințifică „Nicolae Anestiadi – nume etern al chirurgiei basarabene” consacrată centenarului de la nașterea profesorului Nicolae Anestiadi 26 august 2016Introducere. Majoritatea traumatismelor toracice severe (80%) sunt rezultatul politraumatismelor. Acestea reprezintă o entitate asociată unui risc sporit de morbiditate şi mortalitate de până la 15-30%. Leziunea traheobronşică, deşi rară ca incidenţă (1,5-3%), reprezintă un traumatism potenţial letal prin dezvoltarea complicațiilor precoce (insuficiență cardiorespiratorie acută) și tardive (sepsisul pulmonar), care sunt dependente direct de momentul diagnosticării. Scop. Aprecierea factorilor preoperatorii determinanți necesari stabilirii precoce a diagnosticului şi tacticii chirurgicale adecvate în timpi oportuni. Material şi metode. Trei politraumatizaţi (Cr,To,Lo) cu leziune predominantă toracică, vârsta medie – 23,67±2,73ani, raportul B:F/2:1, perioada de referință 2011-2015, cu ISS=38p(3), RTS=6,171(1) și 7,841(2), și TRISS – 20,3%(1), 6,2%(2). În 100% cazuri s-a efectuat hemoleucograma, radiografia toracelui, USG-FAST și FBS, TC doar într-un caz. Durata accident-intervenţie: până la 12h(2), 5zile(1) – transfer AVIASAN. Rezultate. Rx-toracic a evidenţiat: fracturi costale multiple bilaterale(2), unilaterale(1), hemopneumotorace bilateral(2), pneumotorace bilateral(1) și pneumomediastinum(2) cu suspecție de leziune bronşică într-un caz. S-a efectuat toracocenteză bilaterală (100%) și drenarea mediastinului anterior (1). TC a evidențiat fracturile costale, contuzia pulmonară și pneumotoracele persistent. Fluxul aerian continuu prin drenajele montate a impus necesitatea bronhoscopiei diagnostice (100%), care a confirmat leziunea bronșică (BPD – 2, BPS – 1). S-a efectuat toracotomie cu plastia bronhiei lezate(3) și lobectomie superioară dreaptă(1). Evoluția postoperatorie favorabilă, durata de spitalizare – 17,67±2,72zile. Toți au dezvoltat pneumonie, confirmată prin examenele imagistice și paraclinice. Concluzii. Instabilitatea hemodinamică și respiratorie acută, prezența fluxului de aer continuu posttoracocenteză și examenele imagistice impun suspecția leziunii traheobronșice și necesită confirmare prin fibrobronhoscopie. Ultima asigură diagnosticul cert şi determină tactica chirurgicală oportună în timpi efectivi.Introduction. The majority of severe thoracic trauma (80%) result from polytrauma. It is associated with a high risk of morbidity and mortality (15-30%). Despite the rare incidence of tracheobronchial injury (1,5- 3%), the lethality is high due to development of early complications (acute cardiorespiratory failure) and late complications (lung sepsis) that depend directly on the time of diagnosis. Purpose. Appreciation of determinant preoperative factors, necessary to establish on time an accurate diagnosis and surgical treatment. Material and methods. Three polytraumatized patients (Cr,Th,Loco) with predominant thoracic injury, mean age – 23,67±2,73 years, M:F ratio 2:1, hospitalized between 2011-2015. ISS=38p(3), RTS= 6,171(1) and 7,841(2), TRISS – 20,3%(1), 6,2%(2). In 100% of cases investigations include: chest x-ray, FAST and FBS, TC – one case. The time period injury-intervention: up to 12h(2), 5 days(1) – AVIASAN transfer. Results. Chest x-ray revealed: multiple bilateral rib fractures(2), unilateral(1), bilateral hemopneumothorax(2), bilateral pneumothorax(1) and pneumomediastinum(2) with suspicion of bronchial lesion in one case. Bilateral thoracocentesis was performed in all patients, anterior mediastinal drainage – in one. TC revealed rib fractures, lung contusion and persistent pneumothorax. The continuous airflow through drainages required diagnostic bronchoscopy(100%) that confirmed the bronchial lesion (RMB – 2, LMB – 1). Thoracotomy with the plasty of injured bronchus was performed in all patients, right upper lobectomy in 1. Postoperative evolution – favorable, hospitalization period – 17,67±2,72 days. All patients developed pneumonia, confirmed by imagistic examinations. Conclusions. Acute hemodynamic and respiratory instability, the presence of the continuous airflow through drainages and imagistic examinations lead to suspicion of tracheobronchial injury, which required a confirmation by fibrobronchoscopy, that guarantees the right diagnosis and surgical treatment on time

Sensitisation waves in a bidomain fire-diffuse-fire model of intracellular Ca²⁺ dynamics

We present a bidomain threshold model of intracellular calcium (Ca²⁺) dynamics in which, as suggested by recent experiments, the cytosolic threshold for Ca²⁺ liberation is modulated by the Ca²⁺ concentration in the releasing compartment. We explicitly construct stationary fronts and determine their stability using an Evans function approach. Our results show that a biologically motivated choice of a dynamic threshold, as opposed to a constant threshold, can pin stationary fronts that would otherwise be unstable. This illustrates a novel mechanism to stabilise pinned interfaces in continuous excitable systems. Our framework also allows us to compute travelling pulse solutions in closed form and systematically probe the wave speed as a function of physiologically important parameters. We find that the existence of travelling wave solutions depends on the time scale of the threshold dynamics, and that facilitating release by lowering the cytosolic threshold increases the wave speed. The construction of the Evans function for a travelling pulse shows that of the co-existing fast and slow solutions the slow one is always unstable
