Recently, researches have been used Artificial Neural Network (ANN) to predict the early-age thermal cracking of rectangle piers. But ANN has not resulted for different types of concrete piers. This article presents an evaluation of the early-age thermal characteristics of mass concrete piers with four distinct cross-sectional shapes.

Ebook "Raman spectroscopy of conformational rearrangements at low temperatures: Folding and stretching of alkanes in supersonic jets" identifies the turning point in chain length, after which alkanes self-solvate into a folded structure instead of an extended stretched conformation. After this turning point, London dispersion forces rearrange isolated n-alkanes into a particular hairpin-structure, while for shorter chain lengths, a simple stretched conformation is energetically preferred.

Auricular acupuncture (AA) is a method for diagnosing and treating physical and psychosomatic dysfunctions by stimulating a specific point in the ear. In our study, we surveyed the change in temperature of the skin surface at the mandibular area when using AA at the Jaw point on each side of the ear in healthy people.

This specification covers five grades of as-welded, wrought austenitic stainless steel fittings for low-pressure piping and intended for low and moderate temperatures and general corrosive service. Users should note that certain corrosive conditions may restrict the use of one or more grades. For applications requiring a product that requires heat treatment or full pressure rating, refer to Specification A403/ A403M. The term “fittings” applies to butt and socket welding parts such as 45° and 90° elbows, tees, reducers, wyes, laterals, crosses, and stub ends.

The W isotopic compositions have been investigated within the classical approach to the sprocess nucleosynthesis. The Maxwellian averaged neutron capture cross-sections (MACS) adopted in the calculation are obtained from the TALYS-1.9 code with four nuclear level density models: the constant temperature plus Fermi gas, the back-shifted Fermi gas, the generalised superfluid, and the microscopic method of Goriely.

The enhancement of heat transfer from fuel rods to coolant of a Liquid Metal Fast Reactor (LMFR) decreases the fuel temperature and, thus, improves the safety margin of the reactor. One of the mechanisms that increases heat transfer consists of large coherent structures that can occur across the gap between adjacent rods.

Polyacrylamide–montmorillonite (PAAm-Mt) and polyacrylamide–clinoptilolite (PAAm-Z) composites were prepared by cross-linked polymerization of acrylamide in dispersions of Mt and Z. The composites were characterized by FT-IR, SEM, XRD, CEC, and PZC analysis. The adsorptive features of PAAm-Mt and PAAm-Z for methylene blue (MB) were investigated by their relevance to initial dye concentration, temperature, contact time, PZC, and pH.

The synthesis and biological properties of tetra-substituted zinc and cobalt phthalocyanines bearing ethynylpyridine units on the periphery and their quaternized derivatives have been reported. The binding of quaternized ZnPc and CoPc (Q-ZnPc and Q-CoPc) with calf thymus DNA was investigated by UV-Vis spectrophotometric methods and thermodynamics. The mixtures of Q-ZnPc or Q-CoPc and DNA solutions were used to determine the change in the thermal melting temperature of DNA with the thermal denaturation profile.

The synthesis of 3 benzimidazole-based ionic Pd(II)-NHC complexes (NHC:N -heterocyclic carbene) is presented. The structures of the complexes are as follows: [NHC-PdBr3]−[NHC]+. The ionic palladium(II)-NHC complexes were synthesized in high yields and were fully characterized by nuclear magnetic resonance spectroscopy, X-ray diffraction, LC-MS/MS, and elemental analysis. These complexes have been identified as active catalysts in Suzuki–Miyaura reactions in a solution of 2-propanol and water at room temperature for different aryl bromides.

Dy3+ doped lithium-sodium aluminoborate glass (60-x) B2O3-10Al2O3-15Na2O-15Li2O-xDy2O3 (ABLN: Dy3+) are prepared by the conventional melting procedure. Optical absorption and luminescence spectra have been measured at room temperature. Using the Judd - Ofelt (JO) theory, the intensity parameters Ωλ (λ = 2,4,6) have been evaluated for ABLN: Dy3+ glass. These intensity parameters are used to predict radiative properties that include electric (Sed) magnetic (Smd) dipole line strength, radiative transition probabilities (AR), lifetime (τR), branching ratios (βR) for the excited levels of Dy3+.

Microbial transglutaminase (MTGase) is an enzyme widely used in food industry. In this study, MTGases had been applied to produce fresh cheese made from whole milk powder. A set of 18 experiments was carried out to evaluate the influence of factors in reconstituted milk treatment with MTGase. A response surface methodology was applied to evaluate quality properties of fresh cheese via objective functions of hardness, yield, protein content, total solid content and sensory evaluation score. In this model, three factors were enzyme concentration (0.6 - 3.
