Vienas rindas daudzkanālu un vairāku rindu daudzkanālu modeļu matemātiskās analīzes salīdzinājums
2019
Šis darbs ir par vienas rindas daudzkanālu un vairāku rindu daudzkanālu modeļu salīdzināšanu. Darba gaitā tika izvirzītas divas hipotēzes. Pirmā hipotēze: Ja M/M/c modelim ir viena rinda, tad tas ir efektīvāks un tā sagaidāmās kopējās izmaksas ir mazākas nekā M/M/c modelim ar c atsevišķām rindām. Otrā hipotēze: Ja M/M/c modelim ar apkalpošanas prioritātēm ir viena rinda, tad tas ir efektīvāks un tā sagaidāmās kopējās izmaksas ir mazākas nekā tādam pat modelim ar c atsevišķām rindām. Lai apstiprinātu hipotēzes, tika izveidoti divi uzdevumi, kuros salīdzina modeļu efektivitātes rādītājus un sagaidāmās kopējās izmaksas. Darba beigās tiek secināts, ka izvirzītās hipotēzes ir patiesas.
An Expert Opinion From the European Society of Hypertension–European Union Geriatric Medicine Society Working Group on the Management of Hypertension…
2016
Two years after the publication of the 2013 guidelines for the management of arterial hypertension of the European Society of Hypertension (ESH) and the European Society of Cardiology (ESC),1 the ESH and the European Union Geriatric Medicine Society have created a common working group to examine the management of hypertensive subjects aged >80 years. The general term hypertension in the elderly is not sufficiently accurate because it mixes younger old patients (60–70 years) with the oldest old. Our group believes that the management of hypertension in individuals aged ≥80 years should be specifically addressed. Although arbitrary, this cutoff value identifies a population that is expanding …
Physiological and oral parameters contribute prediction of retronasal aroma release in an elderly cohort.
2021
International audience; Malnutrition is a serious problem in the elderly while understanding flavour perception could be a tool for controlling appetite or food choices. To increase our knowledge, we characterised the health and oral physiology (oral volume, swallowing tongue force, number of teeth and salivary flow rate, protein content and antioxidant capacity) of a cohort of 54 community-dwelling French elderly as well as their individual retronasal release of five aroma compounds (2-pentanone, 2-nonanone, 2,3-hexanedione, octanal and linalool) by proton-transfer-reaction mass spectrometry (PTR-MS). In general, large variability across participants was observed in both oral physiological…
Comparative study of the efficacy of olmesartan/amlodipine vs. perindopril/amlodipine in peripheral blood pressure after missed dose in type 2 diabet…
2016
Introduction: Combination therapy is needed to control blood pressure (BP) in a large number of hypertensive patients with diabetes mellitus. Adherence to treatment is a major clinical problem; therefore, the time duration of the antihypertensive action of a drug determines BP control when a dose is skipped. Objectives: The aim was to determine whether the fixed-dose combination of olmesartan/amlodipine provides equal efficacy and safety as the perindopril/amlodipine combination when a drug dose is missed. Methods: In this noninferiority trial with a randomized, double-blind, double-dummy parallel group, controlled design, 260 patients received either olmesartan 20-40 mg/amlodipine 5-10 mg …
Arrhythmias and inhibition of noradrenaline uptake caused by tricyclic antidepressants and chlorpromazine on the isolated perfused rabbit heart
1975
1. Isolated rabbit hearts were perfused with a modified Tyrode solution containing noradrenaline in concentrations increasing stepwise from 5.9 nM to 5.9 μM at 5 min intervals. This dose regime was applied twice before and once 20 min after starting perfusion with one of 9 tricyclic drugs. Ventricular rate and right atrial and ventricular tensions were recorded using the transverse method. 2. Infusions of noradrenaline evoked ventricular arrhythmias in hearts perfused with amitriptyline 4.8 μM, chlorpromazine 5.0 μM, desipramine 5.0 μM, dibenzepine 34.7 μM, doxepin 4.7 μM, imipramine 4.7 μM, noxiptiline 9.1 μM and opipramole 9.2 μM. The incidence of arrhythmias increased with the concentrat…
Comparative Study of the Efficacy of Olmesartan/Amlodipine vs. Perindopril/Amlodipine in Peripheral and Central Blood Pressure Parameters After Misse…
2016
Background Central aortic blood pressure (CBP) and CBP-derived parameters are independent predictors of cardiovascular risk. Angiotensin II receptor blockers (ARBs) or angiotensin-converting enzyme inhibitors plus calcium channel blockers are the recommended first-line treatments in hypertensive diabetic patients; however, the effect in reducing CBP when a dose is skipped has not been established yet. The aim was to determine whether the fixed-dose combination of olmesartan/amlodipine (OLM/AML) provides equal efficacy and safety as the perindopril/AML (PER/AML) combination in reducing CBP, augmentation index (AIx), and pulse wave velocity (PWV) when a drug dose is missed. Methods In this no…

The Grinding Resistance of the Wheat Grain Related to the Grinding Degree For The First Break In The Wheat Milling
2011
Breakage of wheat grain during first break roller milling depends on the characteristics of the wheat (including the distributions of kernel size, hardness and moisture content) and on the design and operation of the roller mill (including roll speeds and differential, roll disposition, fluting profile, number of flutes, fluting spiral, roll gap, the degree of roll wear and the feed rate). The effects of these factors are manifest in the particle size distribution exiting first break, the compositional distribution of those particles (as large particles tend to be richer in bran, while small particles are pure endosperm), the power required to mill the wheat and the rate of roll wear. For t…
Influence of mechanical activation on the physical stability of salbutamol sulphate.
2003
Abstract In order to obtain the optimal particle size distribution for pharmaceutical powders in dry powder inhalers the particles have to be micronised. In most cases the process of micronisation is connected with a high input of energy which induces disorder and defects on the surface of the drug particles and as a result changes in the crystallinity. Consequently, changes in the physical stability of the powders may occur. To investigate changes on the physical stability of the powder, different analytical methods are used in the present investigation: laser diffraction, Differential Scanning Calorimetry (DSC), isothermal microcalorimetry and DVS-method. Air-jet-milling is one of the mos…
