This study aims to determine the Influence of Google Search Intensity on the Stability of the Indonesian Capital Market, as well as looking at the defense and security aspects, especially the economy. The research sample is the shares of the banking sector companies listed on the Indonesia Stock Exchange for the 2016-2018 period. The independent variable used in this study is the Abnormal Search Volume Index. The control variables used are Volatility, and Abnormal Trading Volume Lagged. The dependent variable used is Abnormal Trading Volume. The sampling method used in this study used a purposive sampling technique. Obtained the number of samples as many as 18 companies. The analysis technique used in this research is panel data regression. The results of this study indicate that the intensity of Google searches using the ASVI proxy has a significant positive effect on the stability of the stock represented by Abnormal Trading Volume. This illustrates that the use of Google search intensity data can be used as a reference in making defense policies against non-military threats, especially the stability of the Indonesian Capital Market.

Oil foams stabilized by crystallizing agents exhibit outstanding stability and show promise for applications in consumer products. The stability and mechanics imparted by the interfacial layer of crystals underpin product shelf-life, as well as optimal processing conditions and performance in applications. Shelf-life is affected by the stability against bubble dissolution over a long time scale, which leads to slow compression of the interfacial layer. In processing flow conditions, the imposed deformation is characterized by much shorter time scales. In practical situations, the crystal layer is therefore subjected to deformation on extremely different time scales. Despite its importance, our understanding of the behavior of such interfacial layers at different time scales remains limited. To address this gap, here we investigate the dynamics of single, crystal-coated bubbles isolated from an oleofoam, at two extreme timescales: the diffusion-limited timescale characteristic of bubble dissolution 10,000 s, and a fast time scale characteristic of processing flow conditions, 0.001 s. In our experiments, slow deformation is obtained by bubble dissolution, and fast deformation in controlled conditions with real-time imaging is obtained using ultrasound-induced bubble oscillations. The experiments reveal that the fate of the interfacial layer is dramatically affected by the dynamics of deformation: after complete bubble dissolution, a continuous solid layer remains; while after fast, oscillatory deformation of the layer, small crystals are expelled from the layer. This observation shows promise towards developing stimuli-responsive systems, with sensitivity to deformation rate, in addition to the already known thermo- and photo-responsiveness of oleofoams.

Purpose This paper aims to evaluate how strands of differing investments influence stability in the banking industry using data from 37 countries in Sub-Sahara Africa from 2000 to 2018. Design/methodology/approach Empirical analyses in the study were carried out using a two-step system Generalized Method of Moments estimation methodology. Findings Empirical results suggest that generally, growth in investments by governments, foreign investments and private domestic investments have a significant positive impact in stabilizing the banking industry. The empirical estimates further suggest that macroeconomic conditions such as macroeconomic uncertainty adversely affects the liquid reserve position of banks even during periods of appreciable growth in investments. Originality/value The authors present a different approach to the banking industry discourse. Instead of surmise the relationship with the direction of impact often emanating from the banking industry to other variables of interest or conditions, this study rather examines how investment dynamics among economies influence the stability of the banking industry overtime. In contrast to related studies, this study examines how strands of investment variables influence the stability of the banking industry. Specifically, this study is modeled to examine the extent to which variability in investment growth (using different investment variables) affect stability in the banking industry.

The widely held view that Kellie Lodging (23 High Street, Pittenweem) was built as a townhouse for the Earls of Kellie cannot be correct. The stability of burgage plots in this part of the street shows a reliable match with 16th-century archival data, allowing identification of the occupants of the house at the time it was built (c 1585). Drawings made by Reverend John Sime in 1829 reveal a close historical association between this house and its neighbour at 19–21 High Street, demolished soon after his survey. The occupants of both houses were burgesses, living at a time of acute tension in the town between members of the laird class and the merchants. The siting of the houses at the head of Water Wynd, leading directly to the mid shore, reflects a shift in the town’s focus from the defunct religious area in the Augustinian priory towards a trade-oriented zone around the harbour. Kellie Lodging was the first in the street to have a projecting stair-tower, built not just for display but also for protection in dangerous times. It was quickly followed (1590) by the building of 19–21 with its own stair-tower directly abutting that of Kellie Lodging. Sime’s side-by-side plans of the two houses show the simple L-plan house of Kellie Lodging to be a less ambitious structure than 19–21, which had space to incorporate an inner courtyard to the rear. The street frontage symmetry of the two gables, with an unusual abutment of projecting stair-towers, can be read as a display of solidarity and resolution, as the merchants emerged as the dominant force in the burgh.

The article presents the calculated ratios of indicators determining the stationary states of the lactic acid production process. Three technologies that are most often mentioned in scientific publications are identified: the technology of using strains of microorganisms to produce biomass is a technology that is extremely rarely used; the fairly common technology of using strains of microorganisms to produce lactic acid with the consumption of the main substrate (most often glucose); the promising technology of obtaining lactic acid using, in addition to the main substrate, a component that reproduces the main substrate in the synthesis process. For each technology, the equations of material balance for stationary and non-stationary conditions, a generalized differential equation for non-stationary conditions, and a characteristic equation are given. The formulas for estimating the coefficients of differential equations and the coefficients of the characteristic equation are also given. The equations for non-stationary conditions according to the last two technologies are based on the use of the Taylor series expansion of functions with the preservation of only the first terms of the expansion, i. e. deviations from stationarity in small. The characteristic equation is formed using the eigenvalues . The methodology for all three technologies is given, which allows us to assess the stability of the considered stationary state – the Hurwitz method. For all three technologies, numerical results are obtained for estimating the coefficients of the characteristic equations Pi. Tabular values of the coefficients are given, according to which stability estimates for the dilution rate of 0.1 h–1, 0.2 h–1, 0.3 h–1 are obtained using determinants according to the Hurwitz matrix. The results of numerical estimates for the stability of stationary states for all three technologies are presented. The estimates were based on the indicators of constants published in scientific studies.
