Abstract:

Accelerated curing results, obtained after only 24 hours, are used to predict the 28 day strength of concrete. Various accelerated curing methods are available. Two of these methods are compared in relation to the accuracy of their predictions and the stability of the relationship between their 24 hour and 28 day concrete strength. The results suggest that Warm Water accelerated curing is preferable to Hot Water accelerated curing of concrete. In addition, some other methods for improving the accuracy of predictions of 28 day strengths are suggested. In particular the frequency at which it is

Bacterial nanocellulose (BNC) membranes have enormous potential as systems for topical drug delivery due to their intrinsic biocompatibility and three-dimensional nanoporous structure, which can house all kinds of active pharmaceutical ingredients (APIs). Thus, the present study investigated the long-term storage stability of BNC membranes loaded with both hydrophilic and lipophilic APIs, namely, caffeine, lidocaine, ibuprofen and diclofenac. The storage stability was evaluated under accelerated testing conditions at different temperatures and relative humidity (RH), i.e., 75% RH/40 °C, 60% RH

Abstract:

The zero length column (ZLC) technique is used to investigate the stability of Mg- and Ni-CPO-27 metal–organic framework (MOF) crystals in the presence of water and humid flue gas. The design of the ZLC enables the stability test to be conducted over a considerably shorter time period and with lower gas consumption than other conventional techniques. A key advantage over other experimental methods for testing the stability of adsorbents is the fact that the ZLC allows us to quantify the amount adsorbed of every component present in the gas mixture. The developed protocol is based on a two-stag

Creatine modification for commercialization has included many variations to increase its stability. The current report assesses the stability of a sodium bicarbonate buffered creatine sold under the brand name Kre-Alkalyn under various conditions. Kre-Alkalyn is shown to have a 6 year stability profile under accelerated testing. It maintains a high pH over time compared to normal creatine and can be augmented with additional stabilizing buffers. This stability and buffering profile may serve useful in providing continued creatine availability.

The stability of an in-vitro diagnostic (IVD) medical device reagent is the ability to maintain the performance characteristics over a defined time interval. The stability studies are performed to demonstrate that the product remains viable under the specified storage condition until the claimed time period. Since, stability of the IVD cannot be directly assessed through accuracy, performance attributes or customer testing; it is the responsibility of the manufacturer to evaluate the performance of the product by identifying critical factors affecting the stability through developing stability

Abstract:

The preservation of DNA in biological samples is important for forensic testing, as samples can be tested years or even decades after collection. Generally, the DNA within biological evidence is stable over shorter time frames but can degrade over extended periods. In this work, we evaluated accelerated aging as a method to reduce the duration of studies examining the stability of DNA in forensic evidence-type samples. Evaluation of the DNA extracted from cells stored at 37 and 50°C for 194 or 79 days, respectively, showed similar quality metrics to cells stored at 25°C for 548 days.

Abstract:

Barrier layers for the long-term encapsulation of implantable medical devices play a crucial role in the devices’ performance and reliability. Typically, to understand the stability and predict the lifetime of barriers (therefore, the implantable devices), the device is subjected to accelerated testing at higher temperatures compared to its service parameters. Nevertheless, at high temperatures, reaction and degradation mechanisms might be different, resulting in false accelerated test results. In this study, the maximum valid temperatures for the accelerated testing of two barrier layers were

Therapeutic proteins can degrade upon administration as they are subjected to a variety of stresses in human body compartments. In vivo degradation may cause undesirable pharmacokinetic/pharmacodynamic profiles.

We used a novel approach by stripping serum of endogenous proteins, which interfere with analytical test methods.

Abstract:

This study describes experiments of testing the color stability of heat-treated okan sapwood samples. Heat-treatment was done at 160°C,180°C,200°C,220°C during 4 hours, under steam. series of experiments were carried out to investigate the color stability of heat-treated okan sapwood compared to untreated wood during 100 hours xenon light irradiation. Color measurements during accelerated weathering were made at intervals throughout the test period. The results are presented in △E* and L* a* b*coordinates according to the CIE(1976)L*a*b* parameters color system. Better photo-stability in terms

Abstract:

Demonstrating functional reliability testing of high temperature electronic devices for long lifetime at 300°C requires electrical test fixtures with even better reliability. Advances in complexity of SiC devices and the need for increased accelerated tests motivate the need for a reliable test fixture at high temperature. The design, fabrication and testing of a prototype test board using commercially available materials shows stability beyond 2000 hours. The approach uses an alumina circuit board with thick film conductors interconnecting an array of BeNi contacts to surface pads. The pads a

Abstract:

Due to the growth of the cosmetics industry, developments and improvements are needed for the productive sector and its products to meet consumer demand and the quality standards imposed by inspection bodies. As a result, an area has developed to meet these needs that is known as phytocosmetics. This area involves the inclusion of constituents with of plant origin in the cosmetic product formulation. The objective of this work was to compare the formulations of lip moisturizers incorporating oleoresins and essential oils of cinnamon (Cinnamomun verum), in addition to testing the microbiologica

Abstract:

The stability of the photovoltaic (PV) modules is critical when deployed in a non-ideal environment. Among the different factors, temperature and humidity are the two major factors affecting PV stability, making them significant causes of its degradation in terms of optoelectric and materials properties. Nowadays, with the increase in PV installation (here, we are only taking account of c-Si-based PV modules) to generate green electricity, effective space utilization is an important issue. Recently, people have been considering deploying PV modules on the road to utilize the space available on

Abstract:

The coronavirus disease 2019 (COVID-19) pandemic has led to accelerated efforts to develop therapeutics and vaccines. A key target of these efforts is the spike (S) protein, which is metastable and difficult to produce recombinantly. We characterized 100 structure-guided spike designs and identified 26 individual substitutions that increased protein yields and stability. Testing combinations of beneficial substitutions resulted in the identification of HexaPro, a variant with six beneficial proline substitutions exhibiting higher expression than its parental construct (by a factor of 10) as we
