Assuring high quality of welded joins is a vital task in many industrial branches also when joints are made manually. It the case metal-arc welding with covered electrode. One main imperfection, that can occur this process slag inclusion. In paper an method for detection inclusion multipass manual proposed and validated. The key idea small temperature disturbances will be noticeable consecutive...

Meloxicam is included in the class II Biopharmaceutical Classification System (BCS). This drug has low solubility and high permeability. The one of factors that affect dissolution rate drug. One effort to increase meloxicam by forming a solid dispersion system made using melting method. addition PEG 6000 poloxamer 188 carriers determine aims meloxicam. purpose this study characterize with matri...

Crystal engineering is an integral part of the drug development research. forms can modify physicochemical properties parent molecule. The present work was aimed at synthesis and characterization crystalline product lamotrigine (LT), U.S. Food Drug Administration approved anti-epileptic drug, with citric acid (CA) to improve its release in gastric region oral absorption. products LT?CA were dev...

The paper discusses the application of pulsed microwave radiation for modification crystalline components a high-energy material (HEsM). model aluminized mixture with increased heat combustion was studied. contained 15 wt.% aluminum micron powder, which modified by irradiation. It found that HEM thermogram has an exo-effect maximum at 364.3 °C. use powder in composition energy release during 11...

Defects on rotor blade leading edges of wind turbines can lead to premature laminar–turbulent transitions, whereby the turbulent boundary layer flow forms turbulence wedges. The increased area around is interest here, as it have a negative effect energy production turbine. Infrared thermography an established method visualize transition from laminar flow, but contrast-to-noise ratio (CNR) wedge...

Abstract In this work, the fabricated polylactic acid (PLA) and hybrid natural fiber (NF) biocomposites via a melt extrusion method were investigated. NFs from locally grown plants utilized as fillers. Polyethene glycol (PEG) was used plasticizer to improve processability of PLA. The effect PLA/NF biocomposite processing assessed by mechanical characterization (tensile, modulus, strain at break...

Poly(lactic-co-glycolic acid) (PLGA) is a biocompatible, biodegradable polymer approved by the FDA and EMA, which most widely used in field of health. In this study, PLGA was synthesized primarily from lactide glycolide polycondensation ring-opening polymerization. Then, amino acid derivatives were reaction acids presence 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC). The polymers PLGA, P...
