A Simplified Mechanical Model for Rocking Structures on Compliant Foundations

Housner’s classical rocking model assumes a rigid base, often leading to inaccurate seismic assessments in real-world soil conditions. This study quantitatively establishes the applicability limits of the rigid-base assumption and defines a reference range for its validity. To bridge this gap, a novel Soil-Structure Interaction (SSI)-rocking model is formulated via the Lagrange Equation, capturing the coupled dynamics between rocking blocks and compliant foundations. Crucially, a closed-form relationship is derived to correlate the analytical model’s interface stiffness with the shear and Young’s moduli used in industrial finite element (FE) software. Our findings reveal that rocking behavior depends not only on soil stiffness but also on the inherent stiffness of the structure. Consequently, a relative stiffness parameter is introduced to bridge the analytical and numerical frameworks. Validation using LS-DYNA confirms the model’s precision across varying base stiffnesses. Results indicate that softer soils significantly alter rocking initiation thresholds and amplify peak angles. This proposed analytical model provides a computationally efficient, FE-compatible tool to improve stability predictions and design strategies for unanchored structures in earthquake-prone regions.

Polyhydroxyalkanoates (PHAs) are biodegradable microbial polyesters that represent a promising sustainable alternative to petroleum-based plastics. Salterns, hypersaline environments, are recognized as significant sources of halotolerant microorganisms that can produce PHAs in high-salinity conditions; however, Vietnamese saltern ecosystems have not been extensively investigated. This research aimed to isolate and initially characterize salt-tolerant bacteria capable of synthesizing PHAs from the Hon Khoi saltern in Khanh Hoa province, Vietnam. A total of 37 halotolerant bacterial isolates were obtained, and potential PHA-producing strains were initially screened using Sudan Black B and Nile Blue A. TEM microscopy was then employed to confirm the existence of PHA granules. Furthermore, FTIR spectroscopy and GC–MS/MS spectrometry were utilized to analyze the chemical structure and monomer composition of the extracted polymers. Six isolates were identified as PHA-producing bacteria, including Salinivibrio sp. HK101 and HK116, Halomonas sp. HK105, Priestia sp. HK125 and HK142, and Bacillus sp. HK130. These strains exhibited growth across 3–10% NaCl and temperatures from 25 to 45 °C. Priestia sp. HK142 and Salinivibrio sp. HK101 exhibited the most substantial PHA accumulation, achieving 50.72 ± 1.83% and 42.07 ± 1.8% of DCW, respectively. These results indicate that the Hon Khoi saltern represents a promising source of halotolerant PHA-producing bacteria with potential relevance for future biopolymer production studies.

The Time Interval Only Set, Part 2
Harmen H. Hollestelle
This paper is Part 2 continuing from investigation Part 1 from 2024. To recall, in Part 1, with the derivation of two theorems, defined is an axiomatic approach to the time interval only description. The time interval only set approach is an alternative to the usual one moment time description and the traditional tangent approach of change and differentiation. The two fundamental and nearly equivalent set theorems are the multiplication linearity theorem and the multiplication closure theorem. Both these theorems claim the multiplication of two time intervals results is a time interval. The present paper includes the construction of an overall simultaneous emission example surface for any approximation of spherical symmetric wave emission, applying a variation to a well known construction for indecomposable continua. Several comments and overall theorems are derived that evaluate the example surface construction. These include proof of two new theorems, emission theorem I and II, related to the identity transformation or mapping, which have value in their own right when considered as mathematical theorems. Emission theorem I and II depend on the ‘current parameter’ concept applying a multiple ‘dimensional domain definition’ within both the one moment time and time interval only description, new concepts defined applying set representation theory. Another part of the approach is the linear functional theorem. Within this approach defined is zero and non-zero equilibrium and simultaneous emission with ‘zero’ temperature to be a lowest bound temperature, resembling Boson type of simultaneous emission from collectives of multiple star sources. Finite time intervals being asymmetric this approach can be integrated in Curie’s principle for asymmetry. The current parameter allows for a comment on the fundamental theorem on polynomials. Assuming simultaneous emission internal interaction with em kinematic energy and gravitation energy provides several overall results including introduction of a time interval only description gravitation constant.

Londin et al. discovered miRNAs (LmiRNAs) whose properties had been little studied for unknown reasons. In this study, we examined fully complementary interactions of LmiRNAs with mRNAs of human genes. Using the MirTarget program, a significant number of target genes with unique properties of interaction with LmiRNAs were identified. Of 3707 LmiRNAs in the mRNAs of 75 target genes, the sites of fully complementary LmiRNA binding were located in the 5'UTR with a high free energy of interaction. In the mRNAs of 81 target genes, the fully complementary LmiRNA binding sites (BSs) were located in the CDS. Only seven LmiRNAs bound in the 3'UTRs of target genes. The KIFC3, PHF15, RPL15 and SNX11 genes were identified, encoding LmiRNA-5p and LmiRNA-3p, which bind to the mRNAs of these genes. The mRNA of most genes were bound by only one LmiRNA. The BMP8B, BMP8B, FGFRL1 and SDC3 genes were identified, whose mRNAs bound the pair ID00121.5p and ID02992.5p. These results expand our knowledge of LmiRNAs and allow us to recommend these LmiRNAs as diagnostic and therapeutic agents for various diseases.
