Photocatalytic Degradation of Acephate on ZnFe2O4-TiO2 Photocatalyst under Visible-Light Irradiation

Abstract The ZnFe2O4-TiO2 composite photocatalyst is prepared by sol-gel method and used to degrade acephate successfully. It demonstrates that the photocatalytic degradation of acephate follows pseudo-first-order degradation kinetics (ln(C0/C)=kt). The rate constant k is affected by initial concentration of acephate, pH, catalyst dosage and H2O2 dosage. The lower initial acephate concentration and higher pH value are helpful for increasing the acephate degradation rate. The photocatalyst and H2O2 dosage has the optimal value of 2.0 g L-1 and 8 mmol L-1, respectively. Under the optimized conditions, after 120 min of irradiation, 89.5% acephate can be decomposed.
LEADERSHIP, RISK-TAKING, DECISIONS-MAKING: The newest outcomes from the Science of Leadership

Globalization and digitization have brought in unprecedented changes in the leadership-organization-environment equation. Managing this equation is complex because it is not confined by clear, known boundaries. Today's leadership, in this situation, faces three major challenges: One, they confront problems that are occurring rapidly, are complex in nature, and may be unclear as not having experienced by them before. Two, they have to make quick decisions, in spite of "complexity, novelty and ambiguity" (Lord & Maher, 19901). Three, they have to take risk, keeping in mind "negative consequences of a solution with respect to other on-solving efforts and broader system goals (Mumford & Peterson, 19992). This article addresses the primary, fundamental issue of leadership competencies, which Prof. Fadil Çitaku’s Leadership Competency Model (2012) and currently published Leadership Competency Model Drenica (Çitaku and Ramadani, 2020) propose, and the Leadership Style befitting to the organizational structure that Prof. Don Zilloux, the author of The Results-Focused Organization (2011) elucidates. Additionally, in this study a large body of evidence-based literature have been reviewed to highlight the newest outcomes from the Science of Leadership regarding Leadership, Risk-Taking and Decision-Making.
Fast Two-Stage Computation of an Index Policy for Multi-Armed Bandits with Setup Delays

We consider the multi-armed bandit problem with penalties for switching that include setup delays and costs, extending the former results of the author for the special case with no switching delays. A priority index for projects with setup delays that characterizes, in part, optimal policies was introduced by Asawa and Teneketzis in 1996, yet without giving a means of computing it. We present a fast two-stage index computing method, which computes the continuation index (which applies when the project has been set up) in a first stage and certain extra quantities with cubic (arithmetic-operation) complexity in the number of project states and then computes the switching index (which applies when the project is not set up), in a second stage, with quadratic complexity. The approach is based on new methodological advances on restless bandit indexation, which are introduced and deployed herein, being motivated by the limitations of previous results, exploiting the fact that the aforementioned index is the Whittle index of the project in its restless reformulation. A numerical study demonstrates substantial runtime speed-ups of the new two-stage index algorithm versus a general one-stage Whittle index algorithm. The study further gives evidence that, in a multi-project setting, the index policy is consistently nearly optimal.
Development of Recipe Composition of Bread With the Inclusion of Juniper Using Mathematical Modeling and Assessment of Its Quality

In order to determine the influence of juniper fruits (Juniperus communis L) on the formation of bread quality, the optimization of the component composition of a new product with increased nutritional value was carried out. To optimize the recipe composition, the response surface methodology was used. The maximum value of the complex indicator of the quality of new bread is noted when the mass fraction of sodium chloride is 1.45 % and the mass fraction of crushed juniper fruits is 3.17 %. According to the developed recipe, prototypes of the product were developed and the main quality indicators were determined. Based on the analysis of the chemical composition, it was found that bread with the inclusion of 3 % crushed juniper fruits is characterized by an increased content of protein, fiber, vitamins, micro- and macroelements compared to the control sample. The influence of juniper on microbiological parameters and shelf life of the finished product was established. The new type of fortified bread with the addition of 3 % crushed juniper fruits can be stored without changing the quality indicators for up to 72 hours, which exceeds the same indicator of the control bread sample. In the course of the study, the influence of juniper on the antioxidant activity and safety indicators of bread was determined. The inclusion of crushed juniper fruits in the bread made it possible to double the antioxidant activity compared to the control sample, which is 15.5 and 7.5 mg/100 g, respectively. In terms of safety indicators, the developed bread fully meets the requirements of regulatory documents. The results obtained make it possible to recommend for production a new type of fortified bread with increased nutritional value with the inclusion of crushed juniper fruits in its recipe, which will expand the range of health products
Review on Q Fever: Epidemiology, Public Health Importance and Preventive Measures

Q fever is worldwide zoonotic disease which is caused by obligate intracellular gram-negative bacteria, called Coxiella burnetii. Q fever is air born disease and thus inhalation is considered as primary mode of transmission in both animal and human, sometimes through ingestion they may be infected and ticks play essential role in transmission. The agent is spread a long distance through the wind. The geographical distribution of Q fever is worldwide except New Zealand. The main reservoirs for human infections are cattle, goat, sheep, and pets and ticks are the natural primary reservoir for animal. Coxiella burnetii in ruminant cause reproductive problems like miscarriage, infertility and reduced milk production. The organism can be found in the milk, urine, feces placenta and birth fluids of animals. The airborne transmission of C. burnetii associated with its highly resistance to environments and the ability to easily produce huge quantities of C. burnetii in the after birth of aborted ewes or goats have led to classify C. burnetii as a Category-B, biological terrorism agent. The incubation period of Q fever is depending on the size of infectious. The recommended treatment for ruminant administering two injection of Oxytetracycline during the last month of gestation, also Doxycycline is the best drug. C. burnetii can be reduced in the farm environment by regular cleaning and disinfection of animal facilities. Q fever is global health problem and it is an OIE notifiable disease. Q fever is one of infectious disease which is considered as being having economic and public health importance in Ethiopia. Therefore, awareness creation and, application of prevention and control method has paramount importance in reduce the hazardous effect of this disease.

Obezite Yönetiminde Sağlık İnanç Modelini Kullanma ve Hemşirenin Rolü

Obesity is an important health problem with a gradually increasing incidence in developed and developing countries. In addition to being common, obesity can cause physical diseases such as hypertension and diabetes, psychological problems such as depression and anxiety, and negatively affects quality of life and longevity by increasing mortality and morbidity rates. Obesity affects the country's economy by both resulting deaths and decrease in the labor force and an increase in health spending due to its nature as a chronic disease. Today, it is emphasized that obesity management is necessary to reduce the risks associated with obesity. It is recommended to implement lifestyle changes primarily in obesity management. The nurse's educator role is important in organizing appropriate lifestyle changes. It is necessary to use qualified care models to guide training as well as training strategies in order for training to be effective. The health belief model is described as an effective guide for changing negative lifestyles. This article; The importance of using the "Health Belief Model" and the role of the nurse in obesity management are emphasized.
Biguanidine‐functionalized chitosan to immobilize palladium nanoparticles as a novel, efficient and recyclable heterogeneous nanocatalyst for Suzuki–Miyaura coupling reactions

Biguanidine-functionalized chitosan was synthesized and combined with palladium nanoparticles to yield a recyclable, environmentally benign, heterogeneous catalytic system for the Suzuki–Miyaura C–C coupling reaction. The catalyst was characterized using various techniques. The catalyst was used in Suzuki cross-coupling reactions of various aryl halides, including less reactive chlorobenzenes, with phenylboronic acid to give biaryls without any additive or ligand. A reusability test demonstrated that the catalyst was highly efficient even after six runs. Solid-phase poisoning and leaching tests indicated that the catalyst has a heterogeneous nature.

Advances of Near Infrared Sensitized Radical and Cationic Photopolymerization: from Graphic Industry to Traditional Coatings

This contribution summarizes recent progress in the field of near-infrared (NIR) initiated photopolymerization. The photoinitiator system consists of a cyanine as sensitizer (Sens) and an iodonium salt with distinct structural pattern of both the cation and anion as radical initiator. Both, photonic and thermal events are discussed as the main source for formation of initiating species. Electron transfer between the excited state of Sens (Sens*) and the iodonium salt can be seen as the main source for formation of initiating species such as radicals and protons/electrophiles. Furthermore, the ion mobility as probed by the electric conductivity possesses a major function to tune the reactivity of the photopolymer system. The reactivity of these systems was studied in different applications such as Computer to Plate (CtP), LED curing, photonic baking, and curing of powder coatings with NIR lasers exhibiting line shape focus.

Tourism Development and Air Pollution in Caribbean SIDs: A Bootstrap Panel Granger Causality Analysis

This paper investigates the possibility of Granger causality between tourism development and air pollution in twelve Caribbean small island developing states (SIDs) over the period 1995-2017 in a panel-based model that both allows for the assessment of causality in countries with cross-sectional dependency and heterogeneity and avoids the problem of incorrect specification associated with conventional panel unit root and cointegration tests. The empirical results indicate bidirectional causality between tourism and air pollution for Barbados, Dominican Republic, Jamaica, St. Lucia, and Trinidad and Tobago; unidirectional causality running from tourism to air pollution in Antigua and Barbuda, Cuba, and Guyana; reverse causality from air pollution to tourism in The Bahamas, British Virgin Islands and Haiti, while no causality is found for St. Kitts and Nevis. Our empirical findings provide important policy implications for the Caribbean countries being studied.

Eye tracking analysis of airport flight information display system (FIDS) to improve the information search efficiency

Air transportation is one mode of transport with a large economic contribution to Indonesia (38,12%). The airport must ensure to provide the best service, especially the efficiency of information given. Flight Information Display System (FIDS) is one substantial information system in the airport and aims to increase communication efficiency about the flight information. Based on the preliminary research, the airport’s FIDS showed different visual design one to another. Therefore, this research aims to analyze it to improve information search efficiency. The research used full factorial design as the experimental design method, eye tracker as the data gathering, and mixed-design ANOVA with post hoc test as the data analysis. We involved 3 factors that have a strong correlation with FIDS searching time efficiency: color combination of background and text, row arrangement, and column arrangement. As the measure, time to first fixation and total fixation used to indicate the information search efficiency. Data analysis generated 2 variables that improved information search efficiency on both data, except the row arrangement (only on Total Fixation data). The intended variable levels are dark color background and light color text, row arrangement based on the alphabetic order of the “Flight” column, and column arrangement “Flight-Time-Destination”.
Considerations on Current and Voltage Unbalance of Nonlinear Loads in Residential and Educational Sectors

Most often, electrical consumers in the residential and educational sectors are different from industrial electrical consumers. Whereas the vast majority of industrial electrical consumers are low-voltage, three-phase (with three or four wires), electrical consumers in the residential and educational sectors are low-voltage, single-phase. However, in practice, electrical consumers in the residential and educational sectors are in large numbers. Usually, current and voltage unbalances are lower in the industrial sector compared to the residential and educational sectors, where there are a large number of low-voltage, single-phase consumers that are connected/disconnected in an uncontrollable way and that need to be wired and balanced on each phase of power transformers from power substations. The purpose of this paper is to present the results of electrical balance and improve the power factor in the power substation from residential and educational sectors. The paper investigates the current and voltage unbalance of nonlinear con sumers in the residential and educational sectors. For this purpose, we performed measurements in the laboratory and the power substation to investigate the unbalance in the three-phase system. Laboratory measurements were made in the unbalanced operation of the single-phase electrical consumers connected at three-phase system. The measurements from power substation were carried out after the electrical consumers were uniformly spread among the three phases from the low-voltage power network, on two different days: a workday and a weekend day. The current and apparent power unbalance were reduced and the power factor was improved using the capacitive single-phase electric consumers (e.g., personal computers, which are in large numbers in such sectors) evenly across the phases.
Determination of path attenuation and site characteristics of the North-west Himalayan region and adjoining regions within the Indian Territory using Generalized inversion method

North-west Himalayas and its adjoining regions have been experiencing deadly earthqaukes from time to time and are home for a large portion of population of Indian subcontinent. Knowledge of regional path attenuation and site parameters are prerequisite while attempting seismic hazard studies towards minimizing damages during future earthqaukes for a region. Present work focuses on the determination of path attenuation and site characteristics of earthqaukes recording stations, located in the north-west Himalayas and its adjoining regions, within India. It is done using two- step generalized inversion technique. In the first step of inversion, non-parametric attenuation curves are developed by constraining attenuation to be a smooth decaying function with hypocentral distance. Qs = (105 ± 11)f (0.94 ± 0.08) as S wave quality factor is obtained indicating that the region is seismically active having high degree of heterogeneities in the crustal medium. In the second step of generalized inversion, site amplification curve, at each recording station, is computed as the ratio of site spectral amplitude of horizontal and vertical components. In addition, based on Horizontal to vertical spectral ratio (HVSR) method, predominant frequency of each recording station is calculated. Values of predominant frequencies based on HVSR and generalized inversion are found matching for each of the recording station. Based on obtained predominant frequency, site class of 101 recording stations, which at present are absent, are determined in this work. Determined path attenuation as well as site parameters can be collectively used for developing regional ground motion models and subsequently for seismic hazard studies for the selected region.

COMBINATION OF EMOJI AND TEXT IN MUSICIANS’ TWITTER POSTS

ABSTRACT This research aims to understand the status relation and the way the text and emoji interact in musicians’ twitter posts. This research focuses on the musicians’ twitter posts containing promotion, which also include emoji and text. This research is in a form of a descriptive qualitative which uses the multimodality theory through the generalized image-text relation of Radan Martinec and Andrew Salway. Findings shows that the musicians tend to position the emoji subordinately to text. In terms of logico-semantic relation, the extension relation occurs more than the exemplification relation and enhancement relation. The emoji mostly provides additional information, which cannot be transferred with the text, such as expression and feeling. It is also used to symbolize the event they promote in the post, such as guitar emoji () in a concert promotion. The religious musicians tend to use emoji to provide information about themselves, such as feeling and expression. While, the rock musicians use the emoji more to put information about the event, such as the place and how many days left until the event begins.
Hygienic safety characteristics of bottled water, used for potable water supply

On the basis of the results of performed analysis of literature references concerning influence of phthalates on population health indicators it was found out that their influence at prenatal period may lead to asthma development in children, as well as to allergy, obesity; they also provide anti-androgens effect, leading to growth inhibition and delay in sexual maturation, and to variance of systolic pressure. In case of men phthalates are associated with decreasing of testosterone level and sperms quality, that indicates at their possible role in male sterility. In case of women phthalates are associated with increase of the risk of the second type of diabetes appearance, as well as leiomyoma, endometriosis and breast carcinoma. Laboratory studies performed in accordance with Customs union’s technical regulation ТР ТС 005/2011 enabled to detect phthalates in the packages of bottled water, able to migrate into the bottled water. The results justify the necessity to monitor phthalates in bottled water.
