The Impact of Social Media on the Brand Capital of Famous People

The article is of a research nature. The aim of the article is to identify the role of social media in shaping personal brand. To this end, the first part discusses the concept of personal brand, as well as components of brand capital in the case of famous people, including consumer-based capital. Attention was also paid to the great importance of social media and the growing role of their users in the process of shaping personal brand. Based on the analysis of the source literature, a research gap was identified, related to the lack of empirical verification of the relationship between users’ online activity and and capital of famous people, also known as celebrities, associated with artistic and cultural activities. The article uses the results of the direct research carried out in the period 2019–2020. The second (empirical) part of the article presents research hypotheses, methodology, as well as results and conclusions from the research. Based on 26 in-depth individual interviews that were conducted with people famous in Poland (mainly engaged in artistic and cultural activities) and surveys of a group of 324 social media users, it was shown, among others, that online activity of Internet users stimulates the brand capital of famous people. Statistically significant relationships were observed for such components of the personal brand as awareness/associations with the personal brand and for the relationship regarding the perception of the quality of activities carried out by a famous person.
Green chemistry approach for gold nanoparticles synthesis using plant extracts: a potential material towards catalysis and biology

Plant extracts of amla (Phyllanthus emblica), tea (Camellia sinensis) and coffee (Coffea) are prepared and used for the green synthesis of stable gold nanoparticles. The approach is simple, cost effective and environmentally friendly. The various gold nanoparticles (AuNPs-Amla, AuNPs-Tea and AuNPs-Coffee) are characterised by various spectroscopic and microscopic techniques. The borohydride mediated reduction of 4-nitrophenol is used as a model system to study the catalytic activity of the resulting AuNPs. The reaction rates are quite high following the first order kinetics with first order rate constant of 5.4 × 10−1 min−1, 8.7 × 10−1 min−1, and 2.8 × 10−1 min−1 respectively for AuNP-amla, AuNP-tea and AuNP-coffee. The in vitro cytotoxicity study by MTT assay reveals that the various green synthesised AuNPs are not cytotoxic to living cells and their IC50 values towards two cancer cell lines, MCF-7 and HCT-116 are within the permissible doses. Moreover, IC50 values for AuNPs are in good agreement with direct treatment of aqueous plant extracts.
Pass-Through and C Corp Outputs under TCJA

Corporate finance research focuses on C corps (CCs) neglecting pass-throughs (PTs). We answer this neglect by examining PT outputs for the categories of debt choice, valuation, and leverage gain. In the process, we expand on the nongrowth PT research and supplement the recent CC research on the same outputs. Before the Tax Cuts and Jobs Act (TCJA) became effective in January 2018, PTs had an after-tax valuation advantage over CCs. Under TCJA, we demonstrate this advantage has been reverse. This suggests that, ceteris paribus, a typical PT can now find it advantageous to switch to the CC ownership form. More importantly, we show that nongrowth firm values are comparable to growth firm values unless we assume a rise in growth consistent with projections under TCJA where tax rates are lower. We demonstrate this projected growth increase is the key to make businesses more profitable. Additionally, we show PTs achieve optimal debt-to-firm value ratios (ODVs) well below those for CCs; PTs generally attain slightly higher quality credit ratings at their ODVs compared to CCs; and, PTs have lower leverage gains outputs (in the form of the maximum gain to leverage and the percentage increase in unlevered firm value) compared to CCs.
Evapotranspiration and Precipitation over Pasture and Soybean Areas in the Xingu River Basin, an Expanding Amazonian Agricultural Frontier

The conversion from primary forest to agriculture drives widespread changes that have the potential to modify the hydroclimatology of the Xingu River Basin. Moreover, climate impacts over eastern Amazonia have been strongly related to pasture and soybean expansion. This study carries out a remote-sensing, spatial-temporal approach to analyze inter- and intra-annual patterns in evapotranspiration (ET) and precipitation (PPT) over pasture and soybean areas in the Xingu River Basin during a 13-year period. We used ET estimates from the Moderate Resolution Imaging Spectroradiometer (MODIS) and PPT estimates from the Tropical Rainfall Measurement Mission (TRMM) satellite. Our results showed that the annual average ET in the pasture was ~20% lower than the annual average in soybean areas. We show that PPT is notably higher in the northern part of the Xingu River Basin than the drier southern part. ET, on the other hand, appears to be strongly linked to land-use and land-cover (LULC) patterns in the Xingu River Basin. Lower annual ET averages occur in southern areas where dominant LULC is savanna, pasture, and soybean, while more intense ET is observed over primary forests (northern portion of the basin). The primary finding of our study is related to the fact that the seasonality patterns of ET can be strongly linked to LULC in the Xingu River Basin. Further studies should focus on the relationship between ET, gross primary productivity, and water-use efficiency in order to better understand the coupling between water and carbon cycling over this expanding Amazonian agricultural frontier.
A study on milk quality testing and awareness of science and non science students on milk adulteration

Increased global demand for milk has made it prone to massive levels of adulteration. The aims of this study were to analyze the quality of milk samples and also to assess the awareness of science and non-science students on milk adulteration. A total of 100 milk samples [unbranded (n=50) and branded (n=50)] were randomly collected from different areas of Hyderabad and were chemically analyzed to detect the presence of adulterants using standard procedures. A pre-tested questionnaire was used to assess the knowledge of students (sciences and non-sciences) on milk adulteration. It was observed from the chemical analysis that the unbranded milk samples (n=50) and branded milk samples (n=50) were found to be adulterated with water, cane sugar, urea, detergent, skimmed milk powder and formalin with their extent being 82%, 24%, 12%, 36%, 26%, 22% and 6%, 2%, 0%, 0%, 36%, 28% respectively. It was found from a microbiological examination that 92% of branded milk samples were in good quality, 2% were in fair quality and 6% were in poor quality and all the unbranded milk samples were found to be of poor quality. A significant difference (p<0.05) was observed on the awareness of milk adulteration between Science and Non-Science student respondents. It can be concluded that milk quality is not as per standards. To eradicate this Malpractice, having a quality control system is necessary which could regularly check to ensure good quality milk is sold.
Modeling the Impact of Electric Vehicle Charging Systems on Electric Power Quality

Recently, there has been dynamic development of electromobility. This trend is predicted to grow exponentially, which will contribute to the creation of an extensive infrastructure of electric car charging points. For distribution network operators, this implies that in addition to the increase in demand for power and electricity, the number of converter systems connected to their networks will also increase. It is therefore necessary to determine the potential impact of electric vehicle charging systems on electricity quality. To this end, the authors of the present study developed simulation models based on measurements of the actual charger and the data provided by the manufacturers of the equipment and using simulation models widely described in the literature. On the basis of the study results, the impact of electric car chargers on electric power quality was assessed, and attention was given to the opportunities offered by the development of charging systems with vehicle-to-grid (V2G) functionality. Changes in technical standards aimed at selecting power supply cables by considering their heating under the influence of higher current harmonics generated by converter systems were proposed.
A Numerical Study on the Relation of OH*, CH*, and C2* Chemiluminescence and Heat Release in Premixed Methane Flames

Chemiluminescence (CL) - self emitted radiation from electronically excited molecules - is seen as an attractive option for combustion diagnostics. A successful implementation of CL as a diagnostics tool requires reliable knowledge on the relation between chemiluminescence and heat release. We present results from a numerical study using a detailed kinetic mechanism, for CH4-oxidation [1], incorporating the OH*, CH*, and C2* species. Simulations of one-dimensional premixed laminar flames are performed in lean to rich fuel conditions and at different pressures. The displacement of the peak heat release location from the peak of the excited species concentrations are investigated for its applicability as a potential heat release marker. The results indicate that OH* and CH* are important as a marker for the heat release zone. However, the C2* provides poor estimate on heat release location prediction.
Chief Executive Officer's traits and open innovation in small and medium enterprises: the mediating role of innovation climate

This paper aims to study the impact of Chief Executive Officer's (CEO's) personality traits on open innovation (OI) strategies and the mediating effect of innovation climate by mobilizing the upper echelons theory and the OI literature. In fact, CEO's role in OI promotion has been under-investigated in the literature especially in small and medium-sized enterprises (SMEs) and in developing economies. ,Based on the structural equation modeling, a survey is scheduled by administrating a questionnaire within 178 CEOs in Tunisian high-tech sector. The relevance of the empirical evidences is to disclose human levers to the success of OI strategies in the Tunisian context as a developing country. ,The results show the importance of CEO's entrepreneurial orientation (EO) and attitude in promoting innovation climate and so then OI strategies. The study offers a reading grid for managers of high-tech SMEs to better lead and identify key factors for OI adoption. Innovative climate is found to be a relevant driver of OI encompassing the key role of attitude and EO of top managers. ,Results highlight the relevance of the recruitment of appropriate top managers with high levels of EO and with positive attitude toward OI in order to facilitate OI integration and to enhance SMEs' competitiveness. Entrepreneurially oriented CEOs should be required in order to overcome "Not Invented Here" and "Not Shared Here" syndromes, to support innovative climate and to encourage knowledge import and export in the Tunisian SMEs. ,This paper sheds light on the micro-foundation of OI by emphasizing the relevance of human factors and namely EO and attitude of CEOs in OI issue. It provides conceptual and empirical clarification of the extent to which CEO's traits affect OI through innovative climate. This would value initiatives exploring key individual's characteristics influence on OI strategies within SMEs.
Printed Paper Waste as an Alternative Growing Medium Component to Produce Brassica Seedlings under Nursery Conditions

Significant quantities of paper waste (PW) have been accumulated in recent years and the reuse/recycling of PW is required due to environmental concerns. In the present study, printed PW was used as a peat (P) substitute in growing medium for the Brassica seedlings production, considering recycling, sustainable agriculture, and partly peat replacement. Seeds of cauliflower, broccoli, and cabbage were seeded in growing media made of 0–10–30–50% PW. The addition of PW improved the growing media pH and mineral content, reduced the media aeration, and affected seed emergence. The PW decreased plant growth and the effects were more pronounced at 50% PW. The PW ≥ 30% decreased stomatal conductance, while chlorophyll fluorescence and content of chlorophylls decreased with high PW ratio, negatively affecting the plant physiology. The PW decreased plant sodium and iron and increased potassium, calcium, magnesium, and copper content. The PW increased antioxidant activity to a certain degree for cauliflower and cabbage and resulted in no change for broccoli, while polyphenols increased in cabbage seedlings. The addition of PW did not cause cellular damage as both lipid peroxidation and hydrogen peroxide production remained at low levels, maintaining low levels on the antioxidant enzymes (catalase, superoxide dismutase, peroxidase) metabolism. The present study shows that low PW content can partially replace peat for Brassica seedling production under a sustainable agriculture and environmentally friendly scheme.
Morphometric analysis of the shell of the intertidal gastropod Echinolittorina lineolata (d'Orbigny, 1840) at different latitudes along the Brazilian coast

Abstract Morphometric analysis is one of the tools widely used to quantify, analyse and describe the variations in the biological forms of animals. In this study, we examined the linear morphometric variations of the shell of the small intertidal gastropod Echinolittorina lineolata and compared the patterns to identify variations among populations and between sexes. The individuals were collected from latitudes 3°S, 14°S, 21°S and 23°S along the Brazilian coast. Traditional morphometric analysis was performed, and the morphometric variables of the shells, namely, the length and width of the shell and the length and width of the shell opening were obtained. The observed size pattern was influenced by latitude, as well as by local spatial responses to factors such as the substrate changing the morphometric variables of the snail. Of the morphometric variables, the length and the width of the shell were the most representative variables that influenced the gastropods in the different latitudes. These variables were also different in males and females, with females having larger shell lengths and widths across all latitudes.
A CROSS-SECTIONAL STUDY OF CLINICAL PROFILE OF CEREBRAL PALSY PATIENTS VISITING A GOVERNMENT TERTIARY CARE HOSPITAL FROM MAHARASHTRA, INDIA

Cerebral palsy has emerged as one of the major causes of childhood disability in India. In low and middle income countries there are gaps in knowledge in the spheres of epidemiological research, intervention and service utilization. AIMS AND OBJECTIVES: This study describes the clinical features associated problems of children with CP visiting a government tertiary care Hospital from Maharashtra, India. Materials and Methods: This was cross sectional retrospective observational study conducted on 78 children of cerebral palsy. Result: Among 78 enrolled children, maximum 50%(n=39) of children were between1-3yr age group with male to female ratio was 1.05:1. History of consanguinity was seen in 35.9% (n=28) subjects, 69.2%(n=54)of subjects were from the urban area. 78.2% (n=61) subjects were born term , 65.3%(n=51) cases had a history of NICU stay with the most common etiological factor being birth asphyxia seen in 38.4 %( n=30) subjects followed by sepsis in 29.5% subjects (n=23). Most common type of cerebral palsy was spastic 87.1% followed by dyskinetic 10.2%. Most of the participants were at GMFCS level IV and V (23.1% and 47.4% respectively). 78.2% subjects were having feeding problems, 43.6% had associated epilepsy. Majority of our subjects had Microcephaly (69.2%) and malnutrition (74.3%). MRI was done in only 34.6% of subjects with most common finding being periventricular white matter injury (PVWMI)). Conclusion: It is suggested that rehabilitation clinics should be set up for CP patients at every government medical college so that parents can be made aware of the disease, handicaps, prognosis, and management.
Physical drivers facilitating a toxigenic cyanobacterial bloom in a major Great Lakes tributary

The Maumee River is the primary source for nutrients fueling seasonal Microcystis‐dominated blooms in western Lake Erie's open waters though such blooms in the river are infrequent. The river also serves as source water for multiple public water systems and a large food services facility in northwest Ohio. On 20 September 2017, an unprecedented bloom was reported in the Maumee River estuary within the Toledo metropolitan area, which triggered a recreational water advisory. Here we (1) explore physical drivers likely contributing to the bloom's occurrence, and (2) describe the toxin concentration and bacterioplankton taxonomic composition. A historical analysis using 10‐years of seasonal river discharge, water level, and local wind data identified two instances when high‐retention conditions occurred over ≥ 10 d in the Maumee River estuary: in 2016 and during the 2017 bloom. Observation by remote sensing imagery supported the advection of cyanobacterial cells into the estuary from the lake during 2017 and the lack of an estuary bloom in 2016 due to a weak cyanobacterial bloom in the lake. A rapid‐response survey during the 2017 bloom determined levels of the cyanotoxins, specifically microcystins, in excess of recreational contact limits at sites within the lower 20 km of the river while amplicon sequencing found these sites were dominated by Microcystis. These results highlight the need to broaden our understanding of physical drivers of cyanobacterial blooms within the interface between riverine and lacustrine systems, particularly as such blooms are expected to become more prominent in response to a changing climate.
Non-Constant Elasticity of Substitution and Intermittent Renewable Energy

In this article, we present a model of the electricity sector where generation technologies are intermittent. The economic value of an electricity generation technology is given by integrating its production profile with the market price of electricity. We use estimates of the consumer's intertemporal elasticity of substitution for electricity consumption while parameterizing the model empirically to numerically calculate the elasticity between renewables and fossil energy. We find that there is a non-constant elasticity of substitution between renewable and fossil energy that depends on prices and intermittency. This suggests that the efficacy and welfare effects of carbon taxes and renewable subsidies vary geographically. Subsidizing research into battery technology and tailoring policy for local energy markets can mitigate these distributional side effects while complementing traditional policies used to promote renewable energy.
Degradation of Acid Pharmaceuticals in the UV/H2O2 Process: Effects of Humic Acid and Inorganic Salts

The presence of acid pharmaceuticals in water environments poses a potential threat to ecosystems and human health. Recent research has shown that photo oxidation processes are much more effective for removing these pharmaceuticals. However, the existence of humic acid (HA) could inhibit the clearance efficiency of this process. In this study, we investigated the photochemical degradation of six selected acid pharmaceuticals in surface water and effluent from wastewater treatment plants using the UV/H2O2 process. The results showed that HA can act as a photo sensitizer or a . OH sink, and its concentration had a significant inhibitory effect on the degradation of acid pharmaceuticals. Most of these pharmaceuticals were inhibited during this process when HA was added to deionized water solutions. In addition, the effects of chloride, bicarbonate, and nitrate on the degradation of these pharmaceuticals were different. The removal efficiency of these acid pharmaceuticals is lower in natural samples than in deionized samples because of the complex constituents in the latter.
Heterogeneous Labor Impacts of Migration Across Skill Groups: The Case of Costa Rica

Popular empirical strategies that examine the labor impacts of migrants, like the skill-cell approach, are frequently used to measure the effects of immigrants from a particular skill group on native-born workers with similar skills. I use an augmented version of the skill-cell approach to examine the impacts of immigrants on native workers with similar skills but also across skill groups. I apply this approach to the case of Nicaraguan immigrants in Costa Rica. I find large positive employment and wage effects on high-skilled women arising from low-skilled migrants. These positive effects are derived from both the household channel and the complementary-skills channel. I also find negative but small effects on low-skilled native workers. The results show that immigrants can have complex labor market effects on native workers with own and cross elasticities that can be quite different.
What is the prevalence of dyslipidemia in patients with idiopathic tinnitus?

Background: Dyslipidemia is a metabolic disorder that results from imbalanced and overfeeding as well as sedentary life. Elevated blood lipid levels can affect cochlear blood flow and fluidity, leading to decreased hearing and tinnitus. We aimed to determine whether there is a relationship between tinnitus and dyslipidemia by investigating the blood lipoprotein values of patients with tinnitus.Methods: The lipid profiles of the patients with idiopathic tinnitus who were selected among the patients who applied to Istanbul Haydarpaşa Numune Training and Research Hospital with the complaint of tinnitus between January 2019 and May 2020 were examined. The test results and age and gender distributions were compared with control groups without tinnitus complaints and statistical evaluation was performed.Results: Hypercholesterolemia in 42% of 6472 patients with idiopathic tinnitus, 18% low HDL, 50% high LDL, Hyperlipidemia was detected in 21%. 1942 (30%) of these patients were male; 4530 (70%) are women. The number of patients in the control group without tinnitus was 6470. Hypercholesterolemia in 49% of this group; 21% low HDL, 42% high LDL, 16% hyperlipidemia was detected. In this control group, 1950 (30%) of the patients were male and 4520 (70%) were female. Cholesterol of male and female patients with tinnutus. When the cholesterol, LDL and triglyceride values of HDL and LDL values and female and male patients in the control group were examined, a statistically significant difference was found (p <0.005). No statistically significant difference was found between HDL values of female and male patients with tinnutus and HDL values of female and male patients in the control group (P> 0.05). Conclusions: There is a statistically relationship between tinnitus and dyslipidemia. The presence of dyslipidemia is vital due to atherosclerosis caused by dyslipidemia, especially coronary artery involvement. Therefore, dyslipidemia should be treated as it causes many diseases.
Muslim tourists’ purchase intention of halal food in Spain

ABSTRACT This quantitative study aims to observe the purchase intention of halal food products in Spain from the perspective of Muslim tourists. 500 Muslim respondents who have visited Spain participated in answering our research questionnaire. The data were analyzed using the PLS-SEM method using SmartPLS 3.0 software. Our result shows that both the halal credence and the need for cognition have no direct effects on halal purchase intention. However, halal consumers’ attitude acts as significant mediators in the indirect effects of both halal credence and the need for cognition on halal purchase intention.
