Based on the previous researches, the article also summarizes different perspectives on risk perception, revisit intention, in considering the research trends of this relationship through stages. The research results show that the opposite relationship between these two factors is confirmed by the majority of empirical studies. This is the foundation for establishing policy and governance implications, enabling tourism managers to improve operations, service quality and performance of businesses in tourism.
Development and Metabolic Characterization of Horse Gram (Macrotyloma uniflorum Lam. (Verdc.)) Mutants for Powdery Mildew Resistance

Horse gram is one of the lesser-known beans widely grown in India. One hundred and twenty-three homozygous horse gram mutants were screened for powdery mildew (PM) disease resistance using the grade 0 to 4. The mutants were grouped based on the disease level of 0 to 2 (resistant) and susceptible (3 to 4). The PM altered the chlorophyll fluorescence (a/b ratio), maturity duration, and yield attributing traits. The yield loss ranged from 4.55% to 72.66%. After affirming the resistance level, the resistant mutant (RM) with minimum yield loss (scale:0) and the susceptible mutant (SM) with maximum loss (scale:4) were used for metabolomic analysis through GC-MS. PM infection induced expression of 66 metabolites representing 32 functional classes. The number of unique classes in RM and SM was 13 and 11, respectively, while eight were common. A fold change in the common metabolites indicated an enhanced accumulation of amine, alcohol, and ester in RM. Along with pathogen-induced defensive metabolites, RM produced silane and fluorene, whose biological significance in disease resistance is unknown. Though SM expressed defence-related bio-molecules, it failed to yield better.
Growth Performance and Lipids Profile of Meat of Native Chicken Fed with Feed Substituted with Fermented Banana Peel

This study aims to determine the growth performance, and lipids profile of meat native chicken fed substitution fermented banana peel in feed. Using a completely randomized design, male native chickens (n=200) were randomly distributed into four treatment groups (5 replicates with 10 chickens per replicate). The treatments consisted of T1 (basal diet without substitution). T2, T3, and T4 substitution of fermented banana peel 5, 10, and 15%, respectively. The results showed that the nutrient digestibility of the feed was not affected by the substitution treatment of fermented banana peel in the feed. The performance of native chickens increased significantly (P<0.05) in the feed treatment with fermented banana peel substitution by up to 10%. Dietary substitution with supplementation of banana peel in native chickens decreased the total cholesterol, triglycerides, and HDL levels. It may be concluded that the fermented banana peel can be used as an alternative nutrient in native chicken feed, increasing productivity.
THE INFLUENCE OF RACE AND EMOTION ON COGNITION AND METACOGNITION OF FACIAL PICTURES

"In our daily life, the ability of processing the other people's facial features (such as race, emotion, etc.) are of great significance of us to adapt to social environment and participate in social interaction. In this study, a 2 (race: own-race/ other-race) ×2 (emotion: positive/ negative) within-subjects design was used to investigate how the race and emotion on face affect the processing of cognition and the processing of metacognition. There are five tasks: ease-of-learning (EOL) judgement, remembering, judgement of learning (JOL), recognition and judgement of confidence (JOC). The results revealed that :(1) EOL judgement was only affected by race, which showed that participants made higher EOL judgement for other-race faces than for own-race. (2) The processing fluency was only affected by emotion, which showed that participants spend less time for learning the faces with negative emotion. (3) JOL is not only affected by race, but also moderated by emotion. The results showed that: in the positive emotion condition, JOLs of foreign faces was significantly higher than that of native faces, whereas, in the condition of negative emotion, the difference between the two was not significant. (4) Other-race effect was found in recognition scores, and the other-race effect was moderated by emotion. The results showed that the recognition performance of native face was significantly better than that foreign face in the negative emotion condition. In the condition of positive emotion, the difference between the two was not significant. (5) The trend of confidence judgment was the same as recognition scores. The conclusions were as follows :(1) Emotion has a significant influence on face image cod, while race information has a significant influence on face image cod, and emotional information plays a moderating role; (2) The metacognitive processing of face was influenced by multiple factors such as ethnicity, emotion and cognitive processing information. In conclusion, when processing face image, there is significant separation between cognition and metacognition at different stages, under the influence of ethnicity and emotion. In addition, this study also provides a partial explanation for the difference in accuracy between prospective and retrospective metacognitive monitoring. "
High power wide bandgap cascode switching circuits

Emerging wide bandgap (WBG) power transistors are capable of improving the efficiency of mains voltage power electronic circuits. Several commercial WBG transistors are now available, but all exhibit undesirable gate drive characteristics. The cascode circuit has been suggested as a solution to this problem: WBG cascodes improve the switching speed, gate characteristics and noise immunity of devices, at the expense of greater on-state resistance. WBG cascodes have not, however, been widely accepted in commercial applications. Previous research has typically been too application-specific, with little practical information available for design engineers wishing to use them. This thesis addresses these shortcomings through a comprehensive investigation of practical design considerations for switch-mode cascode circuits. A SPICE simulation and simplified mathematical model are developed as design tools to give a detailed insight into cascode hard-switching behaviour and to aid cascode optimisation and device selection. The effects of the cascode configuration on static (DC) device performance are quantified for a silicon super-junction (SJ) metal-oxide-semiconductor field-effect transistor (MOSFET), silicon carbide (SiC) junction field-effect transistor JFET and SiC MOSFET. The on-state resistance penalty of the cascode configuration is shown to be modest and potentially mitigated by careful selection of HV transistor gate bias. There are few advantages to using silicon SJ MOSFETs in a cascode configuration, but both SiC MOSFET and JFET cascodes benefit from improved gate drive, reverse conduction and switching characteristics. SiC MOSFETs are shown to be better suited to efficient high temperature operation, while SiC JFETs are more appropriate for high current applications. Cascode switching losses are shown to be reduced compared to standalone devices, although reverse recovery losses can counteract this. Methods of controlling switching transients using gate resistors or feedback capacitors are investigated and shown to be effective. The effects of stray inductance on cascode switching are quantified experimentally for the first time. This corroborates other work and informs the layout of cascode circuits. The resilience of cascodes to severe dV dt is also demonstrated. The findings of this thesis are summarised in a practical design guide aimed at design engineers who wish to use this useful circuit.

New uncertainty principles for the Dunkl wavelet transform

After reviewing the Dunkl Pitt and the Dunkl Beckner inequalities we connect both the inequalities to show a generalization of uncertainty principles for the Dunkl wavelet transform. Next we present two concentration uncertainty principles such as Benedick-Amrein-Berthier’s uncertainty principle and local uncertainty principle. Finally, we study the Dunkl logarithmic Sobolev inequalities. Obtaining best possible constants of inequalities, we connect the inequalities to show a generalization of the uncertainty principles of Heisenberg type.
Characteristics, Source Area-weathering, Sedimentary Processes, Tectonic Setting and Taxonomy of Vertisols Developed on Alluvial Sediments in the Benue Trough of North Cameroon

Although Vertisols have been highly documented owing to technological breakthroughs, numerous aspects are still not fully understood such as implication of geochemistry on source area-weathering, provenance, tectonic setting and sedimentary processes as well as problems of classification and management. This work aims to highlight the geochemical characteristics of Vertisols formed on alluvial deposits in the Benue Basin of North Cameroon and to highlight their source area-weathering, sedimentary processes, tectonic setting, taxonomic level and possible management strategies. The work was done in the field and in the Laboratory. The main results showed that smectite is the predominant clay mineral. Chemical composition revealed high Si, Al and Fe contents. Heavy minerals contents are of plutonic (augite, aegerine and aegerinic augerinic augite), metamorphic (kyanite, sillimanite and andalusite) and volcanic (tourmaline) origin. This agrees with the Al2O3/TiO2 ratio of 8.72 to 30.40 reflecting sediments from felsic rocks and minor mafic rocks. The CIA (chemical index of alteration: 70 to 85), PIA (plagioclase index of alteration: 66 to 82) and Ruxton’s index (SiO2/Al2O3: 2.27 to 3.55) suggest a warm and humid climate during moderate to intense chemical weathering probably prevailing during a more humid pre-depositional period. The K2O/Na2O ratio <1 suggests high sediments chemical maturity. The predominance of angular quartz grains suggests short fluvial transport distance and low sorting. The tectonic setting discrimination ternary diagram indicates that alluvial sediments, parent material of Vertisols, originate from an Active Continental Margin while the discriminant function-based multidimensional tectonic diagram indicates an arc-collisional setting suggesting that parent materials are from the Pan-African basement of the Central African Fold Belt. The Vertisols are classified as Ustic Haplusterts Clayey Isohyperthermic (United States Department of Agriculture) and as Gleyic Stagnic Vertisols (Pellic, Hypereutric, Clayic) (World Reference Base for Soil Classification).
Munich Personal RePEc Archive Hours and Wages: A Bargaining Approach

In a recent paper, Bick et al. (2022) show the presence of a hump-shaped relationship between hours and hourly wages with a maximum around 50 hours worked. We show that a model with fixed labor costs where workers and firms bargain in wages and hours can help explain this non-linear relationship. Also, a quantitative version of the model is able to match the empirical hourly-wage to hours worked relationship estimated by those authors for the US. JEL Classifications : C78, E24, J31.
Histological Study on The Effects of Orlistat on Left Ventricular Myocardium of High Fat Diet-Fed Adult Male Wistar Rats

Obesity-induced by a high-fat diet in animal studies recapitulates the human form of obesity. Obesity is a serious public health concern, a risk factor for many diseases, including cardiovascular disorders. Our study evaluated the impact of orlistat on the left ventricular myocardium in high fat diet-induced obese adult Wistar rats. Our study included fifteen adult male Wistar rats weighing between (130-150g). The rats following environmental acclimatization were assigned into three groups A-C (n=5 each), the control (standard rat diet), high-fat diet only, high-fat diet, and orlistat as A, B, and C, respectively. The rats were placed on diets for eight weeks, which performed the sacrifice and histological procedures. The heart and left ventricles were excised and fixed in 10% buffered formalin solution for histological studies. Body Mass Index (BMI) of the high-fat diet-only group markedly increased (P<0.05) relative to the control and the orlistat-treated groups. Heart weight and relative heart weights were not significantly different across the groups. Histological examination of the left ventricular myocardium with the hematoxylin and eosin stain revealed significant deviation from the regular pattern in the high-fat diet-only group. The orlistat-treated group showed a near-normal left ventricular myocardial histoarchitectural pattern. Orlistat ameliorated left ventricular myocardial alteration, restored elastic tissue component, and reversed increased collagen deposition in high fat diet-induced obese male Wistar rats.
Machining of Polymethyl-methacrylate (PMMA) bone cement-based nanocomposite using Combined compromise solution (CoCoSo) theory

Polymethyl-methacrylate (PMMA) bone cement has become an effective biomaterial in orthopedic applications due to its outstanding biocompatibility and mechanical properties. A machining test is essential required while using PMMA bone cement nanocomposite in implant applications. Drilling on the prosthetic product is mainly needed when using PMMA to insert bolts for safety and fixation in the human body. The drilling on bone cement-based prostheses is the most often used machining method during bone-grafting and implant interface surgical procedures. Henceforth, this article focus on the relatively new Combined compromise solution (CoCoSo) theory to study the influence of varying process variables on the drilling performance of Graphene Nanoplatelets (GNP) infused PMMA bone cement nanocomposites. The control of process constraints, namely, GNP weight percentage (Wt.%), spindle speed (SPEED), and drill bit tool material (TOOL) such as HSS, Carbide, and TiAlN, is mainly done to achieve the desired value of Surface roughness (SR) and Material removal rate (MRR) during the drilling experimentation. Using the CoCoSo technique, the optimum setting was attained as Wt. % = 4, SPEED = 1428 rpm, and a Carbide drill bit tool. The synthesized sample was also subjected to an XRD examination to validate the appropriate infusion of nanomaterials in PMMA bone cement. The flexural analysis of the developed nanocomposite sample indicates that mechanical property improves significantly due to the supplement of GNP in PMMA. The findings of the proposed nanocomposites material show its feasibility in biomedical functions. Also, the drilling optimization results demonstrate new criteria to control the quality and productivity indices. It can be recommended for multicriteria optimization case studies.

Merger rate of charged black holes from the two-body dynamical capture

We consider the two-body dynamical capture of black holes carrying U(1) charge which can not only correspond to electric or magnetic charge but also have other physical interpretations such as dark or hidden charge. In the low-velocity and weak-field regime, we study gravitational and electromagnetic radiations from point masses with U(1) charges in a hyperbolic orbit, and we develop a formalism to derive the merger rate of charged black holes from the two-body dynamical capture. We apply the formalism to find the effects of the charge-to-mass ratio on the merger rate for possible different cases and discover that the effects depend on the models.
SMART WATER MANAGEMENT- INNOVATION WITHIN TRADITION

In global water arena, a consensus had been emerged that urban water management urgently calls for smart solutions in order to adapt to climate change. The ways our society is managing water resources are clearly in need of innovation and experimentation, but on the other hand call for reinstatement of traditional knowledge based on locally developed practices of water use. This paper describes a smart water system as a system that implements meaningful data and transforms it into actionable intelligence, but in the same time as a system build upon traditional knowledge. Transect coding is used as research method, to answer the question, how to smartly manage urban water systems at different scales and in different type of urbanized landscape.
PID VS PI CONTROL OF SPEED GOVERNOR FOR SYNCHRONOUS GENERATOR BASED GRID CONNECTED MICRO HYDRO POWER PLANT

Most of the micro hydro power plants operating in isolated mode are based upon induction generator technology. However; in the recent years, there has been a growing interest in the use of synchronous generator based Micro Hydro Power Plants (MHPPs), for grid connected systems, because of the proven advantages over other renewable technologies where the extension of grid systems are economically viable for grid connection. Among various other components of micro hydro power plants, the speed governor mainly functions to control the hydraulic turbine. It constitutes not only the control mechanism but also the actuating equipment to regulate the flow of water, to start and stop the unit, and to regulate the speed and power output of the generator in case of any electrical disturbance. The proper control of actuating devices for these governors plays a significant role in stable and acceptable operation of the connected power system. The use of the Proportional-Integral-Derivative (PID) based control in speed governors is now gaining popularity because of the simplicity and flexibility. This research work makes an effort to analyze the behavior of the PID vs PI (Proportional-Integral) controllers; for speed governor operation of grid connected MHPP, deploying synchronous generator, under the influence of a electrical disturbance; to identify more suitable controller from the regulation point of view. The dynamic performance of the proposed controllers for speed governor function is fully validated through digital simulations carried out using MATLAB/Simulink software package.
Static and Fatigue Load Bearing Investigation on Porous Structure Titanium Additively Manufactured Anterior Cervical Cages

This study investigates the static and fatigue behavior of porous and conventional anterior cervical cages. Porous structure titanium anterior cervical cages were manufactured using direct selective laser sintering technique. Four different types of cervical cages were designed and manufactured, among which three designs consist of porous structure (type 1, type 2, and type 3) and manufactured using metal 3D printing. Remaining one design (type 4) was manufactured using conventional machining and did not consist any porous structure. All types of manufactured cages were tested in compression under static and fatigue loading conditions as per ASTM F2077 standard. Static and fatigue subsidence testing was performed using ASTM F2267 standard. Static compression testing results of type 1 and type 4 cages reported higher yield load when compared to the type 2 and type 3 cages. Static subsidence testing results reported almost 11% less subsidence rate for additively manufactured cages than the conventional cages. Fatigue subsidence testing results showed that type 2 and type 3 cages can withstood approximately 21% higher number of cycles before subsidence as compare to the type 1 and type 4 cages. During fatigue testing, all the cages design survived 5 million cycles at the 3000 N loading. For 6000 N and 8000 N, loading rate type 2 and type 3 cages showed lower fatigue life when compared to other cages design. Since fatigue life of type 2 and type 3 cage designs were reported lower than other cages design, it is concluded that the performance of the additively manufactured porous cages can be significantly varied based upon the cage design features.
ATHLETE-PERCEIVED IMPACT OF FRAME RUNNING ON PHYSICAL FITNESS, FUNCTIONAL MOBILITY AND PSYCHOSOCIAL OUTCOMES

LAY ABSTRACT Frame Running (RaceRunning) allows people with mo-derate-to-severe walking difficulties to walk or run in dependently using a 3-wheeled frame with a saddle and handlebars. In this study 115 Frame Running athletes living in the UK, Sweden or the Netherlands and aged 5 years or over (or their parents) completed a survey about taking part in Frame Running. More than half used a wheelchair or walker for distances over 50 m. Most felt that Frame Running stretched their muscles and increased their self-confidence. Four athletes per ceived extreme fatigue and 17 reported sore muscles after training. Approximately half of the athletes reported that they were less out of breath during mobility tasks (walking, standing) and two thirds reported better functional mobility since they had started Frame Running. Injuries lasting more than 4 weeks were reported by 4 athletes. We conclude that Frame Running is a safe activity with the potential to improve physical fitness, functional mobility, and self-confidence.
