Free-Radical-Induced Degradation of Aqueous Polyethylene Oxide by UV/H2O2: Experimental Design, Reaction Mechanisms, and Kinetic Modeling

The advanced oxidation of aqueous polyethylene oxide (PEO) is studied using the UV/H2O2 process in a batch recirculation photoreactor. The response surface methodology (RSM), combined with quadratic programming, is used for the experimental design, statistical analysis, and optimization of the process. In the second part, a detailed mathematical model is developed to predict the total organic carbon (TOC) removal as a function of time. Continuous distribution kinetics is applied to establish the kinetic model for the photodegradation of PEO. The model is validated at different influential operating conditions using experimental data obtained by a recirculating batch photoreactor. An excellent agreement between the model predictions and the experimental data is confirmed for all experimental conditions. Also, the intrinsic rate constants are estimated using an optimization algorithm. The model provides a good insight into the free-radical-induced degradation mechanisms and kinetics that could be considered for the process optimization.
Ideological Motives and Group Decision-Making

This paper studies experimentally when and how ideological motives shape outcomes in group decision-making scenarios. Groups play a repeated coordination game in which they can agree on a payoff-dominant or a payoff-dominated but ideologically preferred outcome, or disagree and forego all payoffs. We find that groups which disagree initially are more likely to end up agreeing on the ideologically preferred outcome. We classify subjects into ideologically motivated and payoff motivated types and show that this effect stems from the two types’ differential reaction to disagreements. After disagreements, ideologically motivated types are more committed and steer the group towards their preferred outcome. Heterogeneous groups disagree more often and, thus, foster agreements on the ideologically motivated outcome. Our treatments show that, because of this mechanism, large groups are more likely to implement the ideologically preferred outcome than small groups. Furthermore, we show that individual ideological commitment is stronger when it targets the prevention of an outcome in conflict with the ideology than when it targets the implementation of an outcome aligned with the ideology. Theoretically, we study whether fixed or malleable ideological preferences can explain our results.
COMPARISON OF QUALITATIVE CRITERIA IN DECISION ON NUMBER OF COLLAGEN FIBRE FAMILIES IN SOFT TISSUES

: In biomechanics of soft tissues, especially of arteries, collagen fibres play an important role. They are arranged in different directions creating thus fibre families with a main direction and a certain dispersion. The number of this families in different arteries and their layers is still questionable although many researchers presume existence of two helical fibre families. We have analysed histograms published in three papers and shown that the presumption on two fibre families may be misleading; in some cases, unimodal or isotropic distributions gave a better quality of the fit than the bimodal distribution. Although we expected that information criteria could strengthen our objections against the generally applied assumption on two fibre families in arterial wall, this was not confirmed and the preferred approximation function was always the same for both of the compared criteria (Akaike information criterion and coefficient of determination R 2 ).
Experimental and Theoretical Analysis of Fast Lithium Ionic Conduction in a LiBH4–C60 Nanocomposite

We have developed a LiBH4–C60 nanocomposite that displays fast lithium ionic conduction in the solid state. The material is a homogeneous nanocomposite that contains both LiBH4 and a hydrogenated fullerene species. In the presence of C60, the lithium ion mobility of LiBH4 is significantly enhanced in the as-prepared state when compared to pure LiBH4. We also observed that after the material is annealed, the lithium ion mobility is further enhanced. The magnitude of enhancement in lithium ion mobility of the annealed material is comparable to that previously observed for LiX (X = halide) addition to LiBH4. In a LiBH4:C60 70:30 wt % sample that was annealed, we measured Li ionic conductivity of 2.0 × 10–5 S/cm at 25 °C and 2.0 × 10–3 S/cm at 140 °C. Constant current cycling demonstrated that the material is stable in the presence of metallic lithium electrodes. First-principles calculations were also performed to demonstrate how C60 perturbs the interaction of lithium with the borohydride anion yielding a p.
Corona Virus and Food Safety in India– Is the Panic in Customers and Hospitality Industry Warrantable?

Coronaviruses are a virus that are often responsible for causing colds and seasonal flu. In the past have seen Severe Acute Respiratory syndrome (SARS) and Middle Eastern Respiratory Syndrome (MERS), affecting humans. COVID-19 or SARS-COV2 also belongs to these strains of viruses, having first detected in Wuhan China. First discovered in Wuhan seafood market, the virus is said to have been transmitted from Bats to human being. According to WHO food contamination can occur through hands, sneezing and coughing of workers responsible for the preparation and packaging of foods. Similarly, consumption of contaminated or unclean food can cause COVID-19. The origin theory of COVID-19 relating it to food service industry has led to severe mistrust amongst the consumers, and, in turn has caused the hospitality industry to panic. While most of the industry stalwarts are brainstorming the future of the Hospitality industry post COVID-19. Is the panic justified? Agreed as of now, there is a widespread mistrust regarding eating out, or trusting restaurant food, but is there a solution? In this paper we will have a look at how unsafe, eating out is right now? Do the current food preparation norms, fulfil the standards? Is there an overreaction to the COVID-19 Situation? The author has taken liberty to take India as point in case where wider dynamics are at play.

Production of potential functional dairy products using herb treated by microwave radiation

Europe is a significant market of dried herbs and spices; Hungary is one of the most important suppliers [CBI]. 60-70% of the 35-40 thousand tons of the produced drugs are exported [5]. These products are commonly used in dried form. For their microbiological decontamination using ionizing radiation is authorized by the Regulation (EC) No. 1993/3, although their consumption in food products -which do not require further processingcould mean significant risk from the aspect of food safety [8]. However, dried herbs have low water activity, and due to this, they do not favor the growth of the pathogenic microorganisms after the rehydration of these matrixes could mean significant risk factors to food safety [4]. There are not extensive literature data about the microbiological decontamination of the dried herbs and spices, furthermore it is unclarified whether the sterilizing effect is primarily caused by the heat treatment [13], induced by the microwave generated changes of the water molecule’s rotation and friction [11] or to the non-thermal effect of microwave [2; 3; 7]. One of the aims of our study was to produce by our developed technology cheeses and develop a potentially functional food with the addition of the microwave treated herbs. We tried to determine that is there any detectable inhibitory effect of the added herb on the number of microorganisms and in this context, the shelf life of the products [10]. Our study’s main purpose was creating a microbiological stable product using microwave treatment on 2.45GHz frequency, applying lower performance value (900W) like it has been used in the connecting literature [7].
Purcell Factor: A Tunable Metric for Plasmon-Coupled Fluorescence Emission Enhancements in Cermet Nanocavities

We demonstrate an important approach to correlate Purcell factor (PF) and surface plasmon-coupled emission (SPCE) enhancements with the use of finite-difference time-domain (FDTD) simulations and time-correlated single-photon counting (TCSPC) studies of a radiating dipole in cermet nanocavities. We observed >50-fold fluorescence enhancement with high directionality and polarization of Rhodamine 6G (Rh6G) emission trapped in the nanocavity created between the titanium-based ceramic nanoparticle and metallic silver thin film. Compositional variation with hybrid nanoparticles, TiC0N1 (TiN), TiC0.5N0. 5 (TiCN), and TiC1N0 (TiC), brought about enhanced PFs and tunable fluorescence enhancements that were used for mobile-phone-based detection of tryptophan with nanomolar sensitivity. We hope that this study opens the door to next-gen plasmonics with the ability to tune and enhance the hot-spot electromagnetic field intensity of alternative plasmonic materials, as hybrid synergy spacers in the SPCE platform.

Intrinsic motivation and motives for Facebook use - a formative measurement approach

For over a decade, Facebook is part of the everyday life of university students. Its growing popularity stimulated the research aiming to understand the motivations that are driving people to join and use social networking websites. To answer this research question various approaches have been taken: technology acceptance model (TAM), uses and gratification theory, the theory of consumption values, and multidimensional models. The objective of this paper is to analyze the relationship between the intrinsic motivation of using Facebook and the motives for its use. Intrinsic motivation for using Facebook has been conceptualized as perceived enjoyment. The motives for Facebook use have been conceptualized as a formatively-measured construct that impacts two drivers of the intention of use: the perceived enjoyment and the perceived ease of use. The results show that four motives for using Facebook are predicting Facebook's perceived enjoyment: keeping in touch with known people, entertainment, finding useful information and resources, and socialization.

Force approximation of the human hand in contact with a climbing wall handle

This paper presents a new algorithm that approximates the forces that develop between a human hand and the handles of a climbing wall. A hand-to-handle model was developed using this algorithm for the Open Dynamics Engine physics solver, which can be plugged into a full-body climbing simulation to improve results. The model data are based on biomechanical measurements of the average population presented in previously published research. The main objective of this work was to identify maximum forces given hand orientation and force direction with respect to the climbing wall handles. Stated as a nonlinear programming problem, solution was achieved by applying a stochastic Covariance Matrix Adaptation Evolution Strategy (CMA-ES). The algorithm for force approximation works consistently and provides reasonable results when gravity is neglected. However, including gravity results in a number of issues. Since the weight of the hand is small in relation to the hand-to-handle forces, neglecting gravity does not signiﬁcantly aﬀect the reliability and quality of the solution.

SAW-TOOTH SHAPED SEQUENTIALLY ROTATED FRACTAL BOUNDARY SQUARE MICROSTRIP PATCH ANTENNA FOR WIRELESS APPLICATION

This paper presents a new saw-tooth shaped sequentially rotated fractal boundary (SRFB) square microstrip patch antenna (SMPA) for wireless application. The square shape is rotated by an angle ‘θ’ and superimposed, realizing fractal like geometry at boundary. The rotation of square shaped patch is divided in equal number of scaling angles θn such that for every iteration of angle θ, fractal boundary geometry has been realized. The square shape is modified into a circular shape patch resonating at 2.5 GHz. A 45◦ tilted rectangular slot is cut inside the radiating element to achieve circular polarization at 2.45 GHz. The antenna is fabricated using an RT Duroid 5880 substrate, having size of 70 mm×70mm. The antenna offers measured impedance bandwidth (VSWR < 2) of 50 MHz (2%) with simulated peak gain about 7 dBi. The fabricated antenna is tested, and measured results are in close agreement with simulated ones.
Physical Education Survey during the COVID-19 Pandemic in Eastern Indonesia

Almost the whole world was affected by the Study From Home (SFH) policy from Elementary Schools to Higher Education during the Covid-19 Pandemic, however teaching and learning activities did not stop even though the world was facing an outbreak of this disease including Indonesia despite face-to-face teaching and learning activities since last March and schools were not ready to reopen face-to-face teaching and learning activities physically because it was still difficult to implement the Covid-19 prevention health protocol and increasingly massive procedures in educational institutions during face-to-face learning. This study aims to see how the distance learning activities for students are implemented in eastern Indonesia. A total of 432 students from junior high school, high school and tertiary education were sampled in this study. Through this research, data about interest in distance learning can be obtained, as well as what they experience during the distance learning period. This study also provides an overview of difficulties during distance learning, the dominant material and tasks given by the teacher during the Pandemic period as well as inhibiting and supporting factors in distance learning. This study uses a descriptive method, with the research instrument using a questionnaire made through the google form application from respondents and direct visits of subject teachers to students' homes that are not reached by the internet.

Immunohistochemical Expression of CD200 in Renal Cell Carcinoma

Background and Objectives: Renal cell carcinoma (RCC) is the most common malignant renal neoplasm in adults. CD200 is a transmembrane protein and is a promising target for cancer immunotherapy. The aim of this study is to assess the CD200 expression in RCC. Materials and Methods: Eighty paraffin-embedded radical nephrectomy specimens, diagnosed with RCC were evaluated immunohistochemically for CD200 expression. Results: Out of eighty cases studied, CD200 was expressed in n = 73 cases (91.25%) with high intensity in 27 cases (33.75%), moderate intensity in 22 cases (27.5%), and mild intensity in 24 cases (30%). No staining was observed in the adjacent apparently normal renal tissue in all examined sections. No significant relationship was found between CD200 expression and the gender, tumor size, tumor side, histologic type, nuclear grade, T stage, and tumor necrosis. Conclusion: CD200 expression in most of the studied cases of RCC may refer to the potential therapeutic of anti-CD200 antibody for this cancer.
