Abstract This work builds on the iodine-induced stress corrosion cracking (ISCC) model of Lewis and Kleczek by integrating the fuel performance model fuel and sheath modeling tool (FAST) to provide thermal and mechanical analysis of the fuel sheath, which was previously required as input parameters. The iodine transpo…
A new species, Nupela eremica sp. nov. is described from a high mountain lake located in the Eastern Range of Colombian Andes. The new taxon was studied from sediment and epiphyton samples and under light and scanning electron microscope. Comparison with morphologically similar taxa is showed. N. giluwensis, N. caroli…
The use of lathe chucks in machine building companies is the result of a great deal of work and the develop-ment of technical thought. Due to the progress and the possibility of increasing efficiency and at the same time relieving people from work that requires a lot of effort, especially physical effort, the use of b…
With the increasing concern of emerging contaminants (ECs), advanced oxidation processes (AOPs) have been widely investigated to fulfill the drinking water quality because of the potential adverse health effects of ECs. Accordingly, N,N-diethyl-meta-toluamide (DEET) is selected as a model compound belonging ECs to mon…
In consequence, conversion of natural gas (NG) into value added chemicals and fuels has become increasingly important for petrochemical industry, which has noticed the opportunities for new business and technologies, i.e., how to efficiently produce value added higher hydrocarbons from light alkanes. This chapter disc…
The accuracy of a real-time fuel regression measurement by an additive manufactured solid fuel was discussed by comparing with optically measured regression acquired in firing experiments for the conceptual demonstration. The solid fuels that succeeded in fuel regression measurement were manufactured by a multi-materi…
A study of the interaction of methylene blue (MB) with poly(rA)-poly(rU) by the method of fluorescence spectroscopy has been carried out. The data obtained revealed that MB, being a DNA-specific ligand, can bind to double-stranded regions of RNA. In this regard, as in the case of DNA, semi-intercalation was the most p…
The development of next-generation processes that enable the clean and economical conversion of methane to all products that are currently derived from petroleum remains a long-standing, “Grand Challenge” within the field of chemistry. The key challenge with selective methane functionalization is that the oxidation pr…
Nuclear Thermal Propulsion (NTP) is identified as one of the preferred propulsion technologies for future manned missions to Mars and other interplanetary destinations. NTP systems can improve the returns and mitigate the risks of such missions by reducing travel time and improving payload capacity as compared to trad…
The use of abundant natural gas and its efficient conversion to fuels and chemicals has been an important area of research. In addition to energy independence, the development of new technologies that produce no emissions and carbon dioxide-free energy and fuels has also received significant interest in recent decades…
Titanium hydride potassium perchlorate (THPP), which is generally used pressure-producing pyrotechnic initiators, can undergo failure or deviate from the designed performance when subjected to aging. In this paper, we investigated the effects of thermal and hygrothermal aging on the thermodynamic properties of pyrotec…
Chitosan with 80% degree of deacetylation was hydrolyzed by cellulase of Trichoderma viride to prepare chitooligosaccharides (COSs) by the fractionation of the COSs with ultrafiltration membrane. The antioxidant activities of the COSs were clarified in this study by reducing power and free radical scavenging ability a…
Abstract Controlling elastic/acoustic wave-front via compact designs has attracted increasing research interest in past decades. The emerging of metasurface concept provides an unconventional and attractive approach in this filed. A metasurface generally consists of a single array of subwavelength-scaled patterns in t…
Abstract While current neural networks (NNs) are becoming good at deriving single types of abstractions for a small set of phenomena, for example, using a single NN to predict a flow velocity field, NNs are not good at composing large systems as compositions of small phenomena and reasoning about their interactions. W…
Abstract Additive manufacturing methods are becoming more prominent in the world of design and manufacturing due to their reduction of material waste versus traditional machining methods such as milling. The technology to 3D print has been around since the 1970’s. In today’s present time, we now can multi-material 3D…
Abstract The use of conductive fabrics (CF) in the design of wearables for joint sensing has recently received much interest in a wide range of applications such as robotics, rehabilitation, personal wellness, sports, and entertainment. In this paper, we evaluate a new wearable device concept that comprises of a CF st…
Biosorption of heavy metals using plant based materials contributes a significant role in reducing environmental pollution. Here, we investigated removal of hexavalent chromium metal [Cr (VI)] from an aqueous solution by alkali treated novel biosorbent prepared from Calotropis gigantea (L.) Dryand. ex W.T. Aiton leave…
Представлен анализ результатов маркетингового исследования предпочтений потребителей в области спортивного питания Калининграда и Калининградской области. Изучены предпочтения потребителей при выборе спортивных пищевых продуктов. Часто покупаемая форма спортивного питания – батончик, что соответствует форме проектируе…
Reactive hot-melt resin can form joints with a certain flexibility, high processing speed, high initial rigidity, and high temperature. Such resins can be used to manufacture fiberglass composites because they support a high tensile stress, allow for large strains at low stresses, and have a low density and a working…
Abstract The thermal stability of the oligomers obtained by using 2-chloro-2-propen-1-ol as the monomer has been studied. The oligomers were synthesized using chromium(III) and oxovanadium(IV) complexes as the catalysts after activation by modified methylaluminoxane (MMAO-12). The complexes used as the catalysts were…
