Published: December 2020

Abstract
Heat stress in livestock is a function of macro- and microclimatic factors, their duration and intensity, the environments where they occur and the biological characteristics of the animal. Due to intense metabolic processes, high-producing dairy cows are highly vulnerable to the effects of heat stress. Disturbances in their thermoregulatory capability are reflected by behavioural, physiological and production changes. Expression of thermoregulatory behaviour such as reduction of activity and feed intake, searching for a cooler places or disturbances in reproductive behaviours may be very important indicators of animal welfare. Especially maintain of standing or lying position in dairy cattle may be a valuable marker of the negative environmental impact. Highly mechanized farms with large numbers of animals have the informatic system can detect alterations automatically, while small family farms cannot afford these type of equipments. Therefore, observing and analysing behavioural changes to achieve a greater understanding of heat stress issue may be a key factor for developing the effective strategies to minimize the effects of heat stress in cattle. The aim of this review is to present the state of knowledge, over the last years, regarding behavioural changes in dairy cows (Bos Taurus) exposed to heat stress conditions and discuss some herd management strategies provided mitigation of the overheat consequences.

Published: December 2020

Abstract
Weed management is one of the most important and expensive steps in okra production. Field experiments were therefore conducted in the early and late wet seasons of 2015 to evaluate the effectiveness and profitability of weed management using hoe weeding, herbicides or their combination in okra production. Propaben or butachlor at 2.0 kg a.i. (active ingredient) ha–1 followed by (fb) supplementary hoe weeding (shw) at 6 weeks after sowing (WAS) significantly (P < 0.05) reduced weed density and biomass with subsequent increase in okra fruit yield similar to three hoe weedings and better than two hoe weedings or either herbicide applied alone in both early and late wet seasons. Although three hoe weedings provided the highest okra fruit yield (3590 and 4102 kg ha–1) and total revenue ($991.7 and $1699.7 ha–1), the gross margin ($186.4 and $931.6 ha–1) and cost-benefit ratio (0.2 and 1.2) obtained were lower than those obtained with herbicide treatments. Highest gross margin ($470.8 and $1224.9 ha–1) and cost-benefit ratio (1.2 and 3.0) in the early and late wet seasons, respectively, were achieved with propaben at 2.0 kg a.i ha–1 fb shw at 6 WAS. The results of this study suggest that integrated weed management with propaben followed by supplementary hoe weeding will improve weed control, productivity and profitability of okra. Multiple hoe weeding, however, did not guarantee highest profit but rather increased the cost of production.
How Impulsivity influences the Post-purchase Consumer Regret?
Authors: Sokić Katarina , Horvat Đuro , Martinčić Sanja Gutić 
Published: December 2020

Abstract

Background
The role of impulsivity in post-purchase consumer regret is unclear and intriguing because of the negative emotions that underlie both constructs. It is particularly important to examine the impact of impulsivity on the relationship between regret and the Emotionality dimension of the HEXACO model of personality.

Objectives
The purpose of this paper was to investigate the associations between consumer regret components: outcome regret and process regret, attention, motor and non-planning dimensions of impulsivity and Fearfulness, Anxiety, Dependence and Sentimentality domains of Emotionality.

Methods/Approach
The sample consisted of undergraduates from Zagreb, Croatia (M
age = 25.93, 56% females). The correlation and the regression analysis were performed. We used the Baratt impulsivity scale (BIS-11), the HEXACO-PI-R Emotionality scale and the Post Purchase Regret Scale (PPRS).

Results
The PPCR total score was associated with the BIS-11 total score, attention and non-planning impulsivity. Regret due to foregone alternatives was related to attention and non-planning impulsivity, while regret due to a change in significance was related only to attention impulsivity. Regret due to under-consideration positively correlated with non-planning impulsivity.

Conclusions
The results indicate that relations between impulsivity and consumer regret have an important role in understanding consumer behavior and that impulsivity has a moderate association between consumer regret and Emotionality.
The impact of residential suburbanization on changes in the morphology of villages in the suburban area of Wrocław, Poland
Authors: Szmytkie Robert 
Published: December 2020

Abstract
Residential suburbanization is one of the most spontaneous processes occurring in the surroundings of large cities in Central and Eastern Europe. In the case of Wrocław, the first phase of suburbanization began as early as the second half of the 19th century. Its spatial scope changed with the expansion of the administrative borders of the city between 1924-28 and 1950-73, when dozens of suburban villages were incorporated into the city. In addition, during the socialism period, the intensity of suburbanization decreased significantly, which was related to the development of the city within the conditions of planned urbanization and industrialization of the country. The second phase of suburbanization began with the system transformation in the 1990s, and its scale and intensity increased in the 21st century. New construction in the hinterlands of the city has contributed to significant changes in the morphology of suburban villages, especially as the growing share of new buildings is multi-family housing. The aim of this article was to identify the most common trends in the morphological changes that affect villages located in the suburban area of Wrocław under the influence of residential suburbanization. Using the analysis of cartographic materials, field research and graph methods, a typology of morphological transformations of villages located in the suburban area was proposed.

Published: December 2020

Abstract
The aim of this study was to determine the phytochemical content of Moroccan Jujube Honey and to establish the principal components of this staple Moroccan food, which contributes health benefit for the local population. Total phytochemical compounds as determined by analytical HPLC-ESI-MS in the honey extracts were 29.39±5.21 mg/kg (range 16.64–42.16) wet weight. The individual phytochemical compounds definitively identified by HPLC-DAD-ESI-MS in the Jujube honeys were the alkaloids: (I) 4-hydroxyquinoline glucoside, (II) 4-hydroxyquinoline and (V) kynurenic acid (17.66±0.87 mg/kg), and the phenolic compounds: (III) p-hydroxybenzoic acid, (IV) caffeic acid and (VI) methyl syringate (11.73±0.50 mg/kg). The structures were confirmed by GC-EI-MS apart from 4-hydroxyquinoline-glucoside. The major components were methyl syringate (8.34±2.49 mg/kg), 4-hydroxyquinoline (6.61±3.23 mg/kg) and kynurenic acid (6.56±0.97 mg/kg). The mean content of polyphenolic compounds (11.73±0.50 mg/kg) of Moroccan Jujube honeys compared favorably with those described for six Chinese Jujube honeys (2.49 mg/kg), five commercial Jujube honeys from different countries (0.92 mg/kg) and twelve Jujube honeys from Yemen (25.71 mg/kg). Reference studies did not identify alkaloids as components of Jujube honey, and therefore the phytochemical profile of Moroccan Jujube honey appears to be unique.
Complete Approximations by Multivariate Generalized Gauss-Weierstrass Singular Integrals
Authors: Anastassiou George A. 
Published: December 2020

Abstract
This research and survey article deals exclusively with the study of the approximation of generalized multivariate Gauss-Weierstrass singular integrals to the identity-unit operator. Here we study quantitatively most of their approximation properties. The multivariate generalized Gauss-Weierstrass operators are not in general positive linear operators. In particular we study the rate of convergence of these operators to the unit operator, as well as the related simultaneous approximation. These are given via Jackson type inequalities and by the use of multivariate high order modulus of smoothness of the high order partial derivatives of the involved function. Also we study the global smoothness preservation properties of these operators. These multivariate inequalities are nearly sharp and in one case the inequality is attained, that is sharp. Furthermore we give asymptotic expansions of Voronovskaya type for the error of multivariate approximation. The above properties are studied with respect to Lp
norm, 1 ≤ p ≤ ∞.
Governing Illiberal Democracies: Democratic Backsliding and the Political Appointment of Top Officials in Hungary
Authors: Meyer-Sahling Jan-Hinrik , Toth Fanni 
Published: December 2020

Abstract
This paper examines the impact of democratic backsliding on the management of top officials in Hungary. Based on a unique data set of more than 1,600 top officials the article shows that the number of appointments to top positions increased in 2010 and subsequent years, during which Hungary experienced democratic back-sliding. Moreover, the data shows that turnover in top official positions was higher in 2010 and in subsequent years than in the period between 1990 and 2010. The paper concludes that the politicisation and high degree of instability in top official positions may be characteristic of governance in illiberal democracies.
Machine Learning Algorithm for Surface Quality Analysis of Friction Stir Welded Joint
Authors: Mishra Akshansh 
Published: December 2020

Abstract
The Friction Stir Welding process usually produces weld members of good quality compared to composite weld made with a standard welding process. However, there is a possibility of the formation of various defects if the input parameters are not properly selected. In the recent case study, an image-based feature recognition system using the Fourier conversion method which is a computer visual recognition tool is developed. Five types of filters like Ideal Filter, Butterworth Filter, Low Filter, Gaussian Filter, and High Pass Filter. The results showed that the high pass filter has more ability to detect surface defects compared to the other four filters. It has also been observed that the Ideal filter has a lot of distortions compared to the Gaussian Filter and the Butterworth Filter.

Authors: Bhaskar Vennapusa Vijaya , Srinivas Kolla , Rao Devireddy Siva Bhaskara 
Published: December 2020

Abstract
The present work addresses the physical and mechanical properties of banana and palmyra fiber reinforced epoxy composites with the aim of study on the effect of weight ratio and fiber percentage. The banana and palmyra fibers were arranged with different weight ratios (1:1, 1:3, and 3:1) and then mixed with the epoxy matrix by hand lay-up technique to prepare the hybrid composites with various fiber percentages (10%, 20%, 30% and 40%). The properties are measured by testing its density, water absorption, tensile strength, impact strength, hardness and flexural strength and compared. From the results, it was indicated that addition of banana and palmyra fiber in to the matrix material up to 30% by fiber percentage results in increasing the mechanical properties and slightly variation with weight ratios. Interfacial analysis of the hybrid composites were also observed by using scanning electron microscope (SEM) to study the internal failures and micro structure of the tested specimen.

Published: December 2020

Objectives: To determine the current tobacco smoking prevalence among Iranian adults, its geographical distribution in 2011, 2016, and time trend during 2004-2016.Methods: We conducted a pooled analysis of the published reports of 2004, 2007, 2008, 2009, and the data of 2011 and 2016 of the STEPwise approach to chronic disease risk-factor surveillance (STEPS) surveys.Results: The prevalence of current tobacco smoking and current daily cigarette smoking in 2016 was 14.1 and 9.7%, respectively. Only 0.2% of participants smoked water-pipe. Current tobacco smoking prevalence remained unchanged during 2004-2016 for both men and women. The prevalence of passive smoking at home or workplace was 27.4%. Current tobacco smoking prevalence and current daily cigarette smoking was significantly lower among women than men. Current tobacco smoking prevalence showed a geographical pattern throughout the country. In both 2011 and 2016, current tobacco smoking prevalence was higher among men who lived in the western provinces, especially the north-west, than those who lived in the eastern and southern provinces.Conclusions: The current tobacco smoking prevalence among Iranian population has not changed significantly during 2004-2016 and does not conform to the international guidelines. Therefore, it remains crucial yet challenging that effective nationwide policies be implemented to reduce the use of tobacco products. One cannot hope for any reductions in smoking prevalence until a cocktail of interventions are built around strong commitment to government policy.

Evaluating and improving the treatment of gases in radiation schemes: the Correlated K-Distribution Model Intercomparison Project (CKDMIP)
Authors: Hogan Robin J. , Matricardi Marco 
Published: December 2020

Abstract. Most radiation schemes in weather and climate models use the
“correlated k distribution” (CKD) method to treat gas absorption,
which approximates a broadband spectral integration by N
pseudo-monochromatic calculations. Larger N means more accuracy and
a wider range of gas concentrations can be simulated but at greater
computational cost. Unfortunately, the tools to perform this
efficiency–accuracy trade-off (e.g. to generate separate CKD models
for applications such as short-range weather forecasting to climate
modelling) are unavailable to the vast majority of users of radiation
schemes. This paper describes the experimental protocol for the
Correlated K-Distribution Model Intercomparison Project (CKDMIP),
whose purpose is to use benchmark line-by-line calculations: (1) to
evaluate the accuracy of existing CKD models, (2) to explore how
accuracy varies with N for CKD models submitted by CKDMIP
participants, (3) to understand how different choices in the way that CKD
models are generated affect their accuracy for the same N, and (4) to generate freely available datasets and software facilitating the
development of new gas-optics tools. The datasets consist of the
high-resolution longwave and shortwave absorption spectra of nine
gases for a range of atmospheric conditions, realistic and idealized.
Thirty-four concentration scenarios for the well-mixed greenhouse
gases are proposed to test CKD models from palaeo- to future-climate
conditions. We demonstrate the strengths of the protocol in this
paper by using it to evaluate the widely used Rapid Radiative Transfer
Model for General Circulation Models (RRTMG).
Sensing of COVID‐19 Antibodies in Seconds via Aerosol Jet Nanoprinted Reduced‐Graphene‐Oxide‐Coated 3D Electrodes

Published: December 2020

AbstractRapid diagnosis is critical for the treatment and prevention of diseases. An advanced nanomaterial‐based biosensing platform that detects COVID‐19 antibodies within seconds is reported. The biosensing platform is created by 3D nanoprinting of three‐dimensional electrodes, coating the electrodes by nanoflakes of reduced‐graphene‐oxide (rGO), and immobilizing specific viral antigens on the rGO nanoflakes. The electrode is then integrated with a microfluidic device and used in a standard electrochemical cell. When antibodies are introduced on the electrode surface, they selectively bind with the antigens, changing the impedance of the electrical circuit which is detected via impedance spectroscopy. Antibodies to SARS‐CoV‐2 spike S1 protein and its receptor‐binding‐domain (RBD) are detected at a limit‐of‐detection of 2.8 × 10−15 and 16.9 × 10−15 m, respectively, and read by a smartphone‐based user interface. The sensor can be regenerated within a minute by introducing a low‐pH chemistry that elutes the antibodies from the antigens, allowing successive sensing of test samples using the same sensor. Sensing of S1 and RBD antibodies is specific, which cross‐reacts neither with other antibodies such as RBD, S1, and nucleocapsid antibody nor with proteins such as interleukin‐6. The proposed sensing platform could also be useful to detect biomarkers for other infectious agents such as Ebola, HIV, and Zika.
A study on the impact of storage boundary and caprock morphology on carbon sequestration in saline aquifers
Authors: Ahmadinia Masoud , Shariatipour Seyed M. 
Published: December 2020

AbstractStructural trapping is known to be the primary storage mechanism in geological carbon sequestration (GCS), where the injected CO2 rises upwards due to buoyancy forces and becomes trapped under an ultra‐low permeability layer. Although it is relatively common in GCS studies to assume a planar caprock for the synthesised models, in a real scenario this is not always the case as the caprock might exhibit some small‐ or large‐scale topography changes. Moreover, little is known about the impact of the caprock morphology on the CO2 plume migration and the storage capacity. In this work, we performed a preliminary study of the effects of boundary conditions on the CO2 plume migration and dissolution. This was performed because most of the case study models which are employed for GCS studies are part of larger reservoirs. The obtained results were used in the simulation models of the second part of the work, to model an infinite‐acting reservoir appropriately. Three different volume modifier values of 105, 107 and 109 were considered on either one side or both sides of the reservoir for both horizontal and tilted caprock models. The CO2 dissolution in the tilted models was seen to be higher once the multiplier was on the opposite side of the slope. Horizontal models closed on one side (closed faults, salt walls, etc.) were also found to exhibit more significant dissolution than models which were open from both sides. We subsequently investigated the impact of caprock morphology on the CO2 plume advancement and its structural and dissolution trapping mechanisms by performing numerical simulations on nine synthetic models. The dissolution and migration distance are seen to be at a maximum for tilted reservoirs, where the CO2 has more space to migrate upwards and to interact with more formation water. The lowest dissolution occurred where the significant portion of the injected CO2 was trapped in a sand ridge or an anticline. Moreover, the possibility and also the amount of structural trapping was evaluated using an analytical method, and the results showed a fair match with the ones from the numerical simulation. We believe that this methodology could be applied for site screening prior to performing numerical simulations. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.
Disturbance observer‐based two‐Layer control strategy design to deal with both matched and mismatched uncertainties
Authors: Shafei Hamid Reza , Bahrami Mohsen , Talebi Heidar Ali 
Published: December 2020

AbstractThis study presents a novel control strategy for managing nonlinear systems in the presence of mismatched uncertainties. Dealing with the uncertainties that do not satisfy the so‐called matching conditions is an ongoing issue in control engineering. In this regard, and for the first time, a disturbance observer (DO)‐based hybrid control system, which considers robustness as well as control signal optimality, is developed in this article. For this purpose, and with the aim of robustly managing uncertain nonlinear systems and achieving optimized control effort, an optimal control law based on the state‐dependent Riccati equation is integrated with a DO‐based second‐order sliding mode controller. The Lyapunov stability theory is applied to verify the asymptotic stability of the designed control system. Computer simulations are performed to demonstrate the efficacy and the superiority of our novel controller over two other existing methods (DO‐based sliding mode control [SMC] and DO‐based adaptive SMC). The simulation results show that the presented method is capable of managing uncertain nonlinear systems robustly and with much less control effort than the two mentioned methods.

XYZ spin chain with the antiperiodic boundary condition. The key point of our method is that there exist some degenerate points of the crossing parameter ηm,l, at which the associated inhomogeneous T − Q relation becomes a homogeneous one. This makes extrapolating the formulae deriving from the homogeneous one to an arbitrary η with O(N−2) corrections for a large N possible. The ground state energy and elementary excitations of the system are obtained. By taking the trigonometric limit, we also give the results of antiperiodic XXZ spin chain within the gapless region in the thermodynamic limit, which does not have any degenerate points.
