The Kamchatka Peninsula – situated in the Pacific "Ring of Fire" – has 29 active and over 400 extinct volcanoes. Since it is situated in the northeastern extremity of Russia, in subarctic climate,the volcanic landforms are overprinted by the 446 glaciers. This research focuses on the 1^(st) Mutnaya catchment which drains the southern slopes of two active volcanoes: Avachinsky and Koryaksky. Those volcanoes are a permanent threat for the cities of Petropavlovsk and Elizovo, which are the 2 of 3 cities of the peninsula. Hence, most of the studies carried out in the area dealt with the natural hazards and only few focus on landscape evolution. Thus, the purpose of this study was to elaborate a cartographic approach which integrates classic geomorphology with state of the art GIS and remote sensing techniques. As result,different landforms and related processes have been analysed and included in the first general geomorphologic map of the 1^(st) Mutnaya catchment.

POLYMER-SUPPORTED SINGLE AND MIXED AMMONIUM AND PHOSPHONIUM SALTS AS CATALYSTS FOR PHASE-TRANSFER REACTIONS

引用

Chinese Journal of Reactive Polymers 2001年第2期10卷 102-112页

作者： POPA Adriana PARVULESCU Viorica ILIESCU Smaranda ILIA gheorghe DEHELEAN gheorghe Rumanian Academy Institute ofChemistry24 M. Viteazul Str. 1900 Timisoara Roumania. Institute of Physical Chemistry “1.G.Murgulescu" Spl. Independentei 202 Bucharest Romania

In this study was to investigate, by phase-transfer catalysis, the activity of single and mixed ammonium and phosphonium salts grafted on a 揼el-type?styrene-7% divinylbenzene copolymer in the oxidation of benzyl alcohol with hydrogen peroxide. A wide variety of catalysts with different quaternary groups and different quaternary chain length substituents were examined. The activity of single 搊nium?salts increases as a consequence of the association of ammonium and phosphonium salts grafted on the same polymeric support. The activity of polymer-supported ammonium and phosphonium salts increases with the number of carbon atoms contained in the alkyl radicals of the onium and of the functionalization degree with phosphonium groups.

The Relationship between Hypoglycaemic Episodes and Arrhythmias in Type 2 Diabetes Subjects after Acute Myocardial Infarction with ST-Segment Elevation—A Case Series

引用

Journal of Diabetes Mellitus 2022年第2期12卷 141-152页

作者： Roxana Adriana Stoica Diana Frătița Alexandru Scafa-Udriște Oana Florentina gheorghe-Fronea Maria Dorobanțu Constantin Ionescu-Tîrgoviște Cristian Guja Department of Diabetes Nutrition and Metabolic Diseases Carol Davila University of Medicine and Pharmacy Bucharest Romania Department of Cardiology Carol Davila University of Medicine and Pharmacy Bucharest Romania Clinical Emergency Hospital of Bucharest Bucharest Romania

Background and Aims: Several studies have shown that hypoglycaemia, especially a severe episode is associated with an increased mortality rate in diabetes mellitus subjects with previous cardiovascular disease or acute coronary syndrome. One of the presumed mechanisms is the proarrhythmic effect of hypoglycaemia related to the prolongation of the action potential, or the catecholamine surge that follows an episode. The aim of this case series analysis was to investigate the relationship between hypoglycaemia and glucose variability with arrhythmic events in type 2 diabetes patients who suffered an acute myocardial infarction. Materials and Methods: We selected patients admitted consecutively to the cardiology department of Clinical Emergency Hospital in Bucharest for a period of three months with acute myocardial infarction and previously diagnosed type 2 diabetes. For each patient, a retrospective continuous glucose monitoring system (CGMS) or glucose sensor (Medtronic® Enlite, USA) and a dual electrocardiograph and blood pressure monitor for 24 hours were available. Also, patients had an oscillometric device (Arteriograph® TensioMed Ltd) for 24 hours or non-invasive monitoring of central blood pressure, pulse wave velocity and augmentation index. The data were analysed using Medtech®, TensioWin® and Carelink iPro® softwares. We used SPSS® version 20.0 (IBM) for the statistical analysis. The results are presented as median and interquartile range (IQR). Results and Discussion: Ten type 2 diabetes patients (4 males, 6 females) with anterior (4/10) and inferior acute myocardial infarction (6/10) were included. They were treated with insulin (3/10), sulphonylurea (Gliclazide) plus Metformin (4/10), Metformin monotherapy (2/10), or all three (1/10). The patients had a median age of 67.5 (3.25) years with a median disease duration of 8 (7.75) years. The median body mass index was 2

Auto-Scale Factor Circuit Realisation for MIMO Hardware Simulator

引用

Circuits and Systems 2013年第4期4卷 369-385页

作者： Bachir Habib gheorghe Zaharia Ghais El Zein Institute of Electronics and Telecommunications of Rennes (IETR) Rennes France

A hardware simulator reproduces the behavior of the radio propagation channel, thus making it possible to test “on table” the mobile radio equipments. The simulator can be used for LTE and WLAN 802.11ac applications, in indoor and outdoor environments. In this paper, the input signals parameters and the relative power of the impulse responses are related to the relative error and SNR of the output signals. After analyzing the influence of these parameters on the output error and SNR, an algorithm based on an Auto-Scale Factor (ASF) is analyzed in details to improve the precision of the output signals of the hardware simulator digital block architecture. Moreover, the circuit needed for the validation of this algorithm has been introduced, verified and realized. It is shown that this solution increases the output SNR if the relative powers of the impulse responses are attenuated. The new architecture of the digital block is presented and implemented on a Xilinx Virtex-IV FPGA. The occupation on the FPGA and the accuracy of the architecture are analyzed.

MIMO Hardware Simulator: Algorithm Design for Heterogeneous Environments

引用

Circuits and Systems 2013年第2期4卷 217-226页

作者： Bachir Habib gheorghe Zaharia Ghais El Zein Institute of Electronics and Telecommunications of Rennes Rennes France

A wireless communication system can be tested either in actual conditions or by a hardware simulator reproducing actual conditions. With a hardware simulator it is possible to freely simulate a desired type of a radio channel and making it possible to test “on table” mobile radio equipment. This paper presents an architecture for the digital block of a hardware simulator of MIMO propagation channels. This simulator can be used for LTE and WLAN IEEE 802.11ac applications, in indoor and outdoor environments. However, in this paper, specific architecture of the digital block of the simulator is presented to characterize a scenario indoor to outdoor using TGn channel models. The switching between each environment in the scenario must be made in a continuous manner. Therefore, an algorithm is designed to pass from a considered impulse response in the environment to another in other environment. The architecture of the digital block of the hardware simulator is presented and implemented on a Xilinx Virtex-IV FPGA. Moreover, the impulse responses are transferred into the simulator. The accuracy, the occupation on the FPGA and the latency of the architecture are analyzed.
