Efficacy and safety of the glucagon-like peptide 1 (GLP-1) analog oral semaglutide sodium-glucose cotransporter 2 inhibitor empagliflozin were compared in patients with type diabetes uncontrolled on metformin.Patients randomized to once-daily open-label treatment 14 mg (n = 412) or 25 410) a 52-week trial. Key end points change from baseline week 26 HbA1c (primary) body weight (confirmatory secondary). Two estimands addressed efficacy-related questions: policy (regardless trial product...
To compare the efficacy and safety of once-weekly dulaglutide with that insulin glargine in combination metformin and/or a sulphonylurea mainly Asian patients type 2 diabetes mellitus (T2DM).In this 52-week, randomized, parallel-arm open-label study, we enrolled aged ≥18 years T2DM for at least 6 months glycated haemoglobin (HbA1c) concentration ≥53.0 mmol/mol (7.0%) ≤96.7 (11.0%). The primary outcome was change HbA1c from baseline to week 26 determine non-inferiority 1.5 mg versus...
This study describes the method of determining cutting force components in oblique turning. The scheme how investigations were performed is presented. characteristic curves vs. thickness material removed, tool clearance and rake angles are shown. presents data, which have been obtained during experimental analytically calculated, on forces subject to changes depending a cutter angle, depth feed turning operations. analysis approximation results error check theoretical calculations relative...
In the given work we present results of experimental estimation chip shrinkage under turning with straight and radius cutters for two schemes cutting: "direct" "reverse". Ratios thickening, broadening longitudinal were established as parameters. The paper presents graphic charts showing dependences upon cutting depth, supply edge inclination which indicate deformations taking place in area when cup-tip cutters. authors show significant difference character degree working according to various cutting.
The fundamentals of the theory surface acoustic waves (SAW) and principles construction differential SAW-based converters are disclaimed. concept constructing a microaccelerometer, which allows to provide stability device operation in wide temperature range, is presented. Calculation optimal form microaccelerometer console for reducing effect technological errors technology quartz packaging, possibility laser frequency adjustment resonator simultaneous application structures on opposite...
This paper proposes an idea of accelerometer based on surface acoustic waves. Such devices should be able to survive high shocks (up 65 000 g) and still small, energy efficient low-cost. Theory basics, design concepts, experimental modeling results are discussed.
The paper considers the method of determining components cutting force under completed with a radius cutter. authors provide design experimental study. data on change in process turning cutter according to edge inclination, depth and supply obtained experimentally calculated analytically. also provides results work approximation theoretical error checking related data.
The article is presented results of a study the process for dry friction metal-polymer couple on scheme disc-finger. Track membrane from polyethylene terephthalate was research material. Membrane had pores with 0.4 and 0.8 μm diameters. effect sliding velocity membranes microns determined. Research shown that increasing pore's diameter caused reduction coefficient downturn its magnitude vibrations. showed track have adequate resistance to wear can be successfully used in surgical procedures...
The erosion plume resulting from ablation of copper and tantalum targets in vacuum with excimer laser irradiation (308 nm) was studied using Langmuir probe optical emission spectroscopy. ion electron currents were obtained the range energy densities 0.2 to 2.2 J/cm2 at target a probe-to-target distance 10 133 mm. velocity distribution calculated time-of-flight measurements has been revealed as multimodal kind. Curves spatial time dependence current real time. temperature different regions...
Automatization of engineering processes requires developing relevant mathematical support and a computer software. Analysis metal cutting kinematics tool geometry is necessary key task at the preproduction stage. This paper focused on procedure for determining oblique peakless round-nose lathe machining with use vector/matrix transformations. Such an approach allows integration into modern software packages in distinction to traditional analytic description. advantage very promising...
Microtexturing the metal cutting tool surfaces is a novel technique intended for enhancing workability of these tools. The microtexturing used in machining titanium alloys air-space applications reducing adhesion wear blades. This paper focused on forming microtextured dotted, banded and overlapped areas high-speed steel samples. treated have been examined using laser scanning microscopy microtexture pattern roughness. It has shown that obtained samples were free cracks. Surface roughness...
A Langmuir probe was used to study the erosion plume produced during ablation of a tantalum target in vacuum by radiation from an excimer laser at 308 nm. The spatial and temporal dependences electron ion currents were obtained real time. temperature different regions distances measured for first time series current on voltage. nonuniformity its lowering with increasing expansion determined. density determined target.
The possibility of using the acoustic emission method for monitoring cutting process mode is considered. influence mechanical chatter in technological system on parameters signals has been experimentally revealed. It established that a short-term drop spectral power observed transition from steady to regime. In region high-amplitude vibrations, time dependencies median frequency AE decreases, while increases sharply.
