Effectiveness of traditional and digital advertising platforms for the marketing of tourism

This study seeks to measure the effectiveness of traditional media in promoting tourism in this digital age in KwaZulu-Natal, South Africa. This study employed a descriptive research design and a questionnaire was used to collect the data. The findings revealed that traditional and online media are more or less equally competitive in promoting tourism. Traditional media is still effective in promoting tourism in this digital age, especially in the domestic market. The study concluded and recommended that tourism marketers and authorities must come to terms with coexistence with traditional media and online media. There is no need to rely on one media to do it all. Where traditional media is lacking, online media must be there to make up for the difference and enhance the tourist experience.
A statistical method for model extraction and model selection applied to the temperature scaling of the L–H transition

Access to the H mode of confinement in tokamaks is characterized by an abrupt transition, which has been the subject of continuous investigation for decades. Various theoretical models have been developed and multi-machine databases of experimental data have been collected. In this paper, a new methodology is reviewed for the investigation of the scaling laws for the temperature threshold to access the H mode. The approach is based on symbolic regression via genetic programming and allows first the extraction of the most statistically reliable models from the available experimental data. Nonlinear fitting is then applied to the mathematical expressions found by symbolic regression; this second step permits to easily compare the quality of the data-driven scalings with the most widely accepted theoretical models. The application of a complete set of statistical indicators shows that the data-driven scaling laws are qualitatively better than the theoretical models. The main limitations of the theoretical models are that they are all expressed as power laws, which are too rigid to fit the available experimental data and to extrapolate to ITER. The proposed method is absolutely general and can be applied to the extraction or scaling law from any experimental database of sufficient statistical relevance.
Analysis of Bi-Metal Thermostats

The following investigation contains a general theory of bending of a bi-metal strip submitted to a uniform heating. This theory is applied in analysis of operation of a bi-metal strip thermostat. The equations are obtained for calculating the temperature of buckling, the complete travel during buckling, and the temperature of buckling in a backward direction. By using these equations the dimensions of the thermostat for a given temperature of operation and a given complete range of temperature can be calculated. The results obtained are based on certain ideal conditions. For example, it was assumed that the differ­ ence in the coefficients of expansion remained constant during heating, that the friction at the supports could be neglected and that the width
Application of CAD Aided Intelligent Technology in Landscape Design

— The current landscape design methods ignore the depth rendering of scene elements, resulting in low spatial utilization of landscape plant diversity index and landscape spatial pattern. Therefore, this study explores the application of CAD in landscape design. AutoCAD aided intelligent technology is adopted to display the scene in multiple directions and from all angles with terrain design, planning design and planting design as the main contents. Using 3D graphics engine to render landscape elements. On this basis, the spatial coordination planning model of plant landscape is established. The color attribute of landscape space staggered pattern is added to 3D visual reconstruction model by image library function, and the CAD intelligent technology is applied in landscape design. The results shows, the method scored higher in graphic refresh rate, visual brightness and visual contrast, a higher plant diversity coefficient in multiple iterations, and a higher spatial utilization ratio of the landscape pattern than the other two design methods, and the spatial utilization ratio of the landscape pattern of the proposed method is higher than that of the reference method.
R/S Analysis Strange Attractors

A method to estimate the persistent behavior from a chaotic time series is proposed. Persistency means that here each value depends to some extent on the previous values and not only on the recent ones. The data were analyzed by means of Hurst's rescaled range method, i.e., R/S analysis (which was introduced by Mandelbrot and Wallis). The relation of the Hurst exponent to the self-affine and self-simialr fractal dimension is discussed.
Baseline anthropometric measurements and Obesity among students in Sagamu, Ogun State, southwest, Nigeria

Objectives: This study was designed to determine the anthropometric characteristics and prevalence of obesity among secondary and undergraduate students in Sagamu. Methods: This cross-sectional study involved a selection of 260 students aged 10 to 33 years in Sagamu using a convenience sampling method. The weight, height, and waist and hip circumferences of each subject were measured. The body mass index was then calculated. Data were analyzed using SPSS version 25.0 and p-values< 0.05 were considered statistically significant. Results: The age ranges were 1o to 17 years (Secondary school (SS) students) and 14 to 33 years (undergraduate students). There were 130 students in each group, comprising 52.7% males and 47.4% females. Underweight was commoner among the SS students (20.8% versus 6.2%). Most of the subjects were of normal weight 52.3% in SS and 68.5% in undergraduates. Only 3.1% of SS students were obese compared to 4.6% of undergraduate students. The mean BMI of SS students (22.2± 0.39 versus 23.24±0.34) was statistically lower (p=0.019). The mean waist circumference of SS students (66.92±0.44 versus 74.64±0.67) was also statistically lower (p=0.000). The mean BMI of SS students was higher in females than in male subjects (23.14±0.62 versus 20.86±0.42). The mean waist and hip circumferences and BMI were lower in female subjects for both study groups. Conclusions: The mean BMI and hip circumferences were higher in female subjects while the mean waist circumferences were lower in females than males in both study groups.
Sustainable and Scalable Approach for Enhancing the Electrochemical Performance of Molybdenum Disulfide (MoS2)

Molybdenum disulfide (MoS2), the second most thoroughly investigated two-dimensional material after graphene, has attracted considerable interest in energy storage applications owing to its exceptional qualities, including its unique crystal structure, low electronegativity, and high specific capacity. In this study, we showed that a simple ball-milling procedure causes significant improvement in the capacitive properties of the bulk MoS2 (BL-MoS2). We characterized the material before and after the milling process using X-ray diffraction (XRD) and a BET surface area analyzer to find the material’s structural, crystalline features, and surface area, respectively. We prepared electrodes of BL-MoS2 and ball-milled MoS2 (BM-MoS2) for electrochemical investigation. The charge storage characteristics were examined using cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS). The BM-MoS2 and BL-MoS2 have a specific capacitance of 114 F/g and 96 F/g, respectively.
Studies of the solar mean magnetic field with the Birmingham Solar-Oscillations Network (BiSON)

The first analysis of 10 yr of solar mean magnetic field data from the Birmingham Solar-Oscillations Network (BiSON) instrument at Sutherland, SA is presented. Long-period (>1 d) variations correlate well with those observed by the Stanford group, but our daily mean values have a statistical precision over 10 times better than previous work. Differences between the absolute values determined from Sutherland and Stanford are discussed, as are systematic annual variations of the order of 15 per cent. At high frequencies (>0.5 mHz), the mean noise spectral density for our decade of observations is 0.53 G(2) Hz(-1) , setting a lower limit to the noise level than that obtained from brief observations by GOLF on board the ESA/NASA satellite SOHO in 1996. The high-frequency mean noise spectral density is different in different years. The lowest annual value, obtained for 1997, is 0.22 G(2) Hz(-1) , whilst the highest, for 1995, is 1.46 G(2) Hz(-1) . It is not yet clear whether these variations are related to solar activity.

The Effects of Brand Extensions on Market Share and Advertising Efficiency

The authors examine the effects of brand strategy (i.e., brand extensions vs. individual brands) on new product market share and advertising efficiency, and the degree to which these effects are moderated by characteristics of the brand, the product to which it is extended, and the market in which that product competes. The findings indicate that brand extensions capture greater market share and realize greater advertising efficiency than individual brands. The strength of the parent brand is related positively to the market share of brand extensions but has no effect on advertising efficiency. Neither the market share nor the advertising efficiency of extensions is affected by the number of products affiliated with the parent brand. The relative effect of brand extensions on market share is not moderated by the degree of similarity between the extension and other products affiliated with the brand. Advertising efficiency effects, however, are elevated when similarity is high, but only when it is based on intrinsic attributes. Market share and advertising efficiency effects are elevated when the extension is composed primarily of experience attributes and competes in markets where consumers have limited knowledge of the product class. Competitive intensity does not moderate advertising efficiency effects; however, market share effects are elevated when the extension competes in markets comprising few competitors. Finally, both market share and efficiency effects diminish as the extension becomes established in the market.
Interferon-g–Induced Activation of Indoleamine 2,3-Dioxygenase in Cord Blood Monocyte-Derived Macrophages Inhibits the Growth of Group B Streptococci

Neonatal sepsis is most often caused by group B streptococci (GBS) and is a major cause of death in the neonatal period. The response of the immune system in the newborn child has received much attention and is thought to be deficient in a number of ways. The effector response of neonatal monocyte-derived macrophages (MDM) was investigated. Interferon-g induced the activation of indoleamine 2,3-dioxygenase in MDM and inhibited the growth of GBS. Both effects were enhanced by the addition of tumor necrosis factor-a to the culture conditions. The coincident supplementation of L-tryptophan with the bacteria abrogated the bacterial growth inhibition, thus confirming the causative role of L-tryptophan depletion. Control of the extracellular as well as intracellular Ltryptophan levels may thus be one of the effector mechanisms with which the immune system defends the host against GBS dissemination and disease.
Nanocapsules for drug delivery through the skin barrier by tissue-tolerable plasma

For many years, several attempts have been made to enhance skin penetration by chemical, physical or mechanical manipulation to reduce the barrier function of the skin. The present study demonstrates the possibility of penetration enhancement for 400 nm sized nanocapsules loaded with a model drug consisting of a fluorescent dye by the application of tissue-tolerable plasma (TTP). Therefore, the stability of the nanocapsules and their penetration through the skin barrier prior to and in combination with TTP application was evaluated. The results revealed that the penetration of the nanocapsules could be effectively enhanced when applied in combination with TTP, hence delivering the model drug unaffected by plasma into deeper skin layers. The stability testing showed no significant structural changes of the nanocapsules after contact with TTP. Thus, the present study introduces a new strategy for the penetration enhancement of substances by the combined utilization of nanocapsules and TTP.
Horizontal Wind Systems in the Ionospheric E region Deduced from the Dynamo Theory of the Geomagnetic Sq Variation Part IV

Horizontal wind systems in the ionospheric E region are deduced along the same line as in a previous paper [1]. This time, however, the wind systems on both northern and southern hemispheres in the solstice season are obtained. The wind systems thus obtained represent the actual state instead of the mean state as in Part I and II [1] [3], in the solstice season. In Part IV the effect of the Coriolis force is taken into account and an advance is made in the treatment in Part III where the wind velocity is simply assumed to be irrotational [4]. It is shown, as in Part III, that in summer the diurnal wind motion is predominant over the semi-diurnal, whereas in winter the velocity of the former is almost the same as that of the latter. Further the diurnal wind velocity is greater in summer than in winter and the semi-diurnal wind velocity is somewhat smaller in summer than in winter.Some differences are found between the results of Part III and IV. However, more observational material than available at present must be accumulated before discussing these differences,

End-of-line delivery vehicle routing optimization based on large-scale neighbourhood search algorithms considering customer-consumer delivery location preferences

Logistics is an important guarantee for economic and social development. Among the various aspects of logistics, the urban logistics end distribution link, which involves the direct connection between distribution personnel and customers, has a direct impact on customers' sense of experience and satisfaction with logistics services. At present, there are unscientific and unreasonable selection methods for logistics end distribution paths, often based on the subjective experience of distribution personnel, which often results in a mismatch between distribution paths and distribution needs, affecting market demand while further increasing the distribution costs of enterprises. Therefore, based on the characteristics of customer-consumers, this paper considers that consumers can select multiple receiving addresses, and each address has a corresponding time window limit. This paper finds that it needs to spend a lot of costs for the enterprise to improve the service level of distribution, and the enterprise can save the cost from time window, as well as obtain the better distribution time by using alternative addresses through the verification and analysis of an example. Based on the above analysis, this paper proposes the urban logistics terminal distribution path optimization path based on large-scale neighbourhood search algorithm, which can promote the further matching between logistics distribution enterprises and customer needs, so as to improve the probability of consumers receiving goods in time as well as reduce the cost of enterprises.
A bipolar outflow in the globule Lynds 810

A high angular resolution map in (C-12)O has been made of the large globule L810 which reveals an outflow associated with a cluster of embedded young stellar objects and a water maser. It is argued that two stars are responsible for the outflow. The morphology of the regions of redshifted and blueshifted high-velocity emission resembles that of a biconical flow model, with both cones intersecting the line of sight and each cone producing both blueshifted and redshifted emission. This is the first outflow identified with this flow geometry. The high-velocity gas is very optically thick in (C-12)O and is clumpy with beam filling factor around 0.4 in the central part of the outflow region. The mass of the globule with a radius of 2 arcmin is estimated to be 300-600 solar masses. The total mass of the globule is about 750 solar masses. 38 refs.
Highly efficient broadband anisotropic metasurface for cross polarization conversion operating in the terahertz band

Terahertz (THz) band has been attracting an enormous reputation due to the paucity of natural materials in this range. Artificially flat thin films, called metasurfaces, plead the research community owing to their unprecedented features to manipulate the scattering properties of electromagnetic (EM) waves. Capitalizing on these unique attributes of the metasurfaces, a wideband polarization converter is investigated for THz frequencies. The proposed metasurface rotates the incoming EM wave into its cross-component over a broad spectral range from 1 THz to 1.75 THz. The designed polarization conversion metasurface (PCM) manifests above 90% efficiency, having a bandwidth of 0.75 THz. This unit cell is also scalable to other operating regimes such as microwave and visible, just by scaling its physical dimensions. This kind of wideband PCM remains prudent for various applications of radar cross-section reduction (RCSR), imaging, communication, etc.
Evaluating the sustainability of agritourism in the wild coast region of South Africa

Abstract In recent decades, agritourism has been proposed by various agencies as a strategy for the sustainable development of rural areas and the diversification of the rural economy. The study aimed to examine and identify the role of agritourism in entrepreneurship and sustainability. Semi-structured interviews were used to collect data from 15 business owners and 68 residents from local households on the Wild Coast. Consequently, various facets of agritourism for sustainable rural development were investigated using a qualitative research method. The findings revealed that agritourism in the study area can be enhanced by integrating it with farm entrepreneurship. Furthermore, because many disenfranchised families already engage in crafts, subsistence farming, fishing, and other activities, agritourism has the potential to lift many of them out of poverty.
Half - Quantum Vortices

Unlike to superfluid $^4$He the superfluid $^3$He-A support the existence of vortices with half quantum of circulation as well as single quantum vortices. The singular single quanta vortices as well as nonsingular vortices with 2 quanta of circulation have been revealed in rotating $^3$He-A. However, the half quantum vortices in open geometry always possess an extra energy due to spin-orbit coupling leading to formation of domain wall at distances larger than dipole length $\sim 10^{-3}cm$ from the vortex axis. Fortunately the same magnetic dipole-dipole interaction does not prevent the existence of half-quantum vortices in the polar phase of superfluid $^3$He recently discovered in peculiar porous media "nematically ordered" aerogel. Here we discuss this exotic possibility. The discoveries of half-quantum vortices in triplet pairing superconductor Sr$_2$RuO$_4$ as well in the exciton-polariton condensates are the other parts of the story about half-quantum vortices also described in the paper.
Cavitation Bubble Collapse in Viscous, Compressible Liquids—Numerical Analysis

Collapse of a spherical bubble in a compressible liquid, including the effects of surface tension, viscosity, and an adiabatic compression of gas within the bubble is investigated by numerical solutions of the hydrodynamic equations. A limiting value of shear viscosity causes the bubble collapse to slow down markedly, for both compressible and incompressible liquids, whereas moderate viscosities have very little effect on the rate of collapse. The inclusion of surface tension and viscosity introduces two scaling parameters into the solution, so that a single normalized solution is no longer sufficient to describe collapse behavior. The magnitude of the density changes calculated for the compressible liquid and the extremely rapid changes with time suggest that the usual Navier-Stokes equation of motion may not be appropriate. The possibility of liquid relaxational phenomenon and its contribution to sonoluminescence is considered. Shock waves or damagingly high pressures are not generated during collapse at a distance in the liquid equal to the initial radius from the center of collapse, although they will appear at such a distance if the bubble rebounds.
The effect of facade deterioration on urban life: a historical analysis of the Korba area in Cairo

In heritage conservation and revival, much of the focus is placed on the techniques and methods to preserve, restore, and revive heritage structures and locations. However, less research examines how deterioration happens and effects they have on the area’s character and socio-economic status. To this end, this research aims to examine the decline and its effect in the El Korba area in Heliopolis, Cairo, Egypt. El Korba was designed with a unique architectural character to stimulate social and economic life. However, the area has been on a path of physical deterioration that is corroding the social life on its streets. Previous research proposed a framework that connected six street-level façade design parameters to the social interactions on streets and sidewalks: complexity and architectural character, permeability, territoriality and personalization, enclosure, ground-floor use, and physical comfort. This research builds on this framework to study the changes in El Korba’s buildings’ architectural features through a diachronic analysis in Ibrahim El-Lakkani Boulevard of El Korba using descriptive analysis. Architectural features of the street level during both the original state (1906) and the current state (2021) are broken down and categorized in those six parameters to understand their decline or improvement over time.
