Transforming Hotel Supply Chain Using Intelligent Decision Support System: Prospects and Challenges

Modern technological innovations are driving the trends to digitalize the hotel supply chains. The most famous and used technologies are artificial intelligence, robotics, blockchain, and advanced predictive analytics. These technologies provide the tools that will inevitably redesign and transform many aspects of the hotel supply chains. Thus, this study aims to investigate the opportunities and chart the path to adopt the Intelligent Decision Support System (IDSS) in hotel supply chain management. IDSS is a computerized information system that facilitates the decision-making process by creating alternatives, which can then be evaluated using a set of predetermined patterns to make reliable and fact-based decisions. To that end, this study engaged in 12 Delphi survey with hotel managers and key industry experts in Egypt and received additional inputs from 70 structured surveys conducted amongst four and five-star hotels located in Cairo, Giza, Alexandria, Sharm El-Sheikh, and Hurghada which allow a deeper insight into the prospective scenarios of how IDSS could be applied in hotel supply chain management. The results unveiled that the hotel supply chains in Egypt are moving towards digital transformation, albeit with slow steps. Also, the results revealed that data quality, analytical decision-making capabilities, and transformational impacts appear to be critical factors that influence the adoption of IDSS. A key finding of this study is that Egyptian hotels cannot reap the integration advantage of IDSS technology without additional engagement with supply chain partners.
Changes in hippuric acid in composting processes of different animal bird manure

Utilizing animal bird manure simulating in door composting was carried out. The dynamic change of hippuric content, influence factor in composting process and the variation of hippuric acid content in different manure were studied. The hippuric acid content in different kinds of animal bird manure was in the order of cow manure pig manure chicken manure. The hippuric acid content in cow manure was high reaching 129.48mg/kg, pig manure was in 81.80～85.99mg/kg, while chicken manure was in 42.62～45.11mg/kg. The content of hippuric acid all drastically increased with composting, then decreased slowly, after 42d decreasing to lower than initial value. The hippuric acid change speed and range of different manure were different at different composting stages of different manure. After 14d of degrading, the relation between hippuric acid decomposting rate and time could be better simulated using regression equations v=A+B lnt. The change trend of hippuric acid content and temperature, pH value was identical. Logically, in composting process, humifficating action was one reason of hippuric acid content lowering.
Economic legacy effects of armed conflict: Insights from the civil war in Aceh, Indonesia

The province of Aceh in Indonesia provides a promising case for studying the economic legacy effects of conflict given subnational district-level data on violence and gross domestic product. We demonstrate specific negative economic legacy effects of armed conflict despite a general peace dividend: whilst all districts in Aceh grow faster after conflict ends in 2005 than during the conflict, the districts that suffered relatively more from violence during the war grow relatively more slowly during peacetime than districts that experienced relatively little violence. These negative legacy effects are relatively short-lived, however, and are no longer statistically significant from 2009 onwards. JEL classification: O40, O47, Q54
Enhancement of self-healing to mechanical properties of concrete

Concrete is the main construction material of many structures. Exposing to loads creates cracks in concrete, which reduce the performance and durability. The decrease of concrete cracks becomes a necessity demand to ensure more durability and structural integrity of the concrete structure. Autogenous healing concrete is a kind of new smart concretes, which has the ability to reclose its cracks by means of itself. Concrete self-healing is a type of free repairs processes, which is reduce direct and indirect cost of maintenance and repairing. This work targets to inspect the mechanical properties of concrete after using two combinations of two materials (20 kg/m3 calcium hydroxide Ca(OH)2 and 2 kg/m3 sodium carbonate Na2CO3 and 30 kg/m3 calcium hydroxide and 3 kg/m3 sodium carbonate) as a partial replacement of cement to work as self-healing agents. The paper reports and study the compressive, flexural and splitting tensile strengths and ultrasonic pulse velocity tests’ results at 7, 28 and 90 days of concrete age. Use of two combinations of calcium hydroxide and sodium carbonate, as healing agents, enhanced the mechanical properties of concrete and reduced the width of concrete cracks with time. The concrete compressive strength was increased after curing for 90 days by 9.3 and 11.1 %, respectively. The flexural strength was improved by 14.3 and 15.9 %, respectively. Also, the splitting tensile strength was enhanced by 6.9 and 9.3 %, respectively.
Positive Selection Affects the Expression of Systemic Lupus Erythematosus Associated Loci in Human Populations

Background: Systemic lupus erythematosus (SLE) shows marked population-specific disparities in disease prevalence, including substantial variation in manifestations and complications according to genetic ancestry. Several recent studies suggest that a substantial proportion of variation of gene expression shows genetic ancestry-associated differences in gene regulation on immune responses. Positive selection may act in a population-specific manner on expression quantitative trait loci (eQTLs) and thereby contributes to the difference in the differences of SLE prevalence and manifestation in human populations. We tested the hypothesises that some of the identified SLE risk polymorphisms display pleiotropic effects or polygenicity driven by positive selection. We performed a genome-wide scan for recent positive selection by using integrated Haplotype Score (iHS) statistics in different human populations. In addition, we estimated the timing of beneficial mutations to understand what possible selective pressures drive positive selection at SLE-associated loci. Results: We identified several SLE risk loci that are population-specifically under positive selection. Almost all SNPs that are under positive selection function as cis-eQTLs in different tissue types. We determined that adaptive eQTLs affect the expression of fewer genes than non-adaptive eQTLs, suggesting a limited range of effect of an eQTL at SLE risk sites that show signatures of positive selection. Furthermore, some positively selected SNPs are located in transcription factor binding sequences. The timing of positive selection for the studied loci suggests that both environmental and recent lifestyle changes during as well as after the Neolithic Transition may have become selectively effective. We propose a novel link between positively selected eQTLs at a certain SLE risk locus in Europeans and a physiological pathway not previously considered in SLE.Conclusions: We conclude that population-specific adaptive eQTLs contribute to the observed variation in specific manifestations and complications of SLE in different ethnicities. Our results suggest also that human populations adapt more rapidly to environmental and lifestyle stimuli via modification of gene expression without having to alter the genetic code.
What Drives Closed-End Fund Discounts? Evidence from COVID-19

This paper investigates the impact of the onset of the COVID‐19 pandemic in the United States on closed‐end fund (CEF) discounts. I show that CEF discounts increased after the onset of the COVID‐19 pandemic in the United States, while individual investor sentiment declined. Furthermore, CEFs with higher retail ownership had a larger discount increase, which suggests that individual investor sentiment is a potential contributor to CEF discounts. This finding seems less likely to be driven by rational channels or income‐driven fire sales, as shown by further analysis. Overall, the results shed light on the CEF discount puzzle using a new setting.
Effects of including core strengthening exercise as part of a comprehensive rehabilitation programmes on people with lower-limb amputation: a pilot study

Exercise can be a useful rehabilitation approach for people with lower-limb amputation. However, there is a lack of research in this regard. The aim of this study was to analyse functional mobility, walking speed, range of motion and quality of life changes experienced by people with lower-limb amputation after taking part in a comprehensive exercise programme that included core strengthening exercises. This was a pilot study including six individuals who carried out a comprehensive exercise programme, which was performed once a week for 5 months. During the first 2 weeks, the participants attended 1-hour sessions that focused on the execution of diaphragmatic breathing and body scheme exercises. From the fourth week until the end of the intervention, the sessions were much longer, and included a warm-up phase, two circuit training workouts for core strength and balance, and a final stretching routine. Significant improvements were found in the participants' functional mobility (P=0.007) and walking speed (P=0.001). The exercise intervention did not have a significant impact on the participants' range of motion and quality of life. In a group of people with lower-limb amputation, the performance of a comprehensive exercise programme that included core strengthening, was found to be beneficial for functional mobility and walking speed, although no significant effect was observed for range of motion and quality of life measures.
EFFECTS OF ZEOLITE (Clinoptilolite) ON SOME WATER AND GROWTH PARAMETERS OF RAINBOW TROUT (Oncorhynchus mykiss WALBAUM, 1792)

The effects of zeolite (Clinoptilolite (CL)) added into pond water, on some water and growth parameters of rainbow trout (Oncorhynchus mykiss Walbaum, 1792), were investigated, in the present study. CL was added into water by 0 (control), 1, 2, 3 mg l -1 rates and carried out in 100 days. The results of the study showed that average body weights of fish in group were respectively, 128.242±4.748 g, 126.623±5.545 g, 126.349±0.339 g and 126.556±7.663 g and average total lengths were 21.870±0.355 cm, 21.340±0.341 cm, 21.783±0.255 cm and 21.191±0.193 cm. However, there was no statistical difference among groups for all parameters (P>0.05). At the end of the study, there was no statistical difference among groups for water parameters (P>0.05), but an obvious decreasing was observed in nitrate rates during study and in ammonium and nitrite rates during only first period.
A Model of Damage for Brittle and Ductile Adhesives in Glued Butt Joints

The paper presents a new analytical model for thin structural adhesives in glued tube-to-tube butt joints. The aim of this work is to provide an interface condition that allows for a suitable replacement of the adhesive layer in numerical simulations. The proposed model is a nonlinear and rate-dependent imperfect interface law that is able to accurately describe brittle and ductile stress–strain behaviors of adhesive layers under combined tensile–torsion loads. A first comparison with experimental data that were available in the literature provided promising results in terms of the reproducibility of the stress–strain behavior for pure tensile and torsional loads (the relative errors were less than 6%) and in terms of failure strains for combined tensile–torsion loads (the relative errors were less than 14%). Two main novelties are highlighted: (i) Unlike the classic spring-like interface models, this model accounts for both stress and displacement jumps, so it is suitable for soft and hard adhesive layers; (ii) unlike classic cohesive zone models, which are phenomenological, this model explicitly accounts for material and damage properties of the adhesive layer.
Clinically Reliable Knee Flexion Angle Measured on Stress Radiography for Quantifying Posterior Instability in Posterior Cruciate Ligament Injury

Background: After posterior cruciate ligament injury, stress radiography is a common method of quantifying posterior instability, defined as the side-to-side difference in posterior tibial displacement (PTD) between the injured knee and contralateral noninjured knee. However, no study has evaluated the reliability of PTD according to knee flexion angle (KFA) measurements on stress radiographs. Purpose: To evaluate the test-retest reliability of stress radiographic measurements of the KFA in the noninjured knee. In addition, we established a reliable range of KFAs to indicate posterior instability by comparing results with the instability measured at 90° KFA, which is considered the gold standard. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: We evaluated patients who had undergone bilateral stress radiographic examinations at least 5 times for ligament injuries between January 2013 and November 2019. All examinations were performed on a Telos device with a 150-N posterior load. A total of 120 knees and 644 stress radiographs were enrolled. We measured the KFA and PTD on stress radiographs and evaluated the reliability of repeated PTD measurement and the correlation between KFA and PTD. Results: The distribution of the actual noninjured knee KFA ranged from 56.9° to 106.7°. Among the 644 radiographs, 155 (24.1%) showed KFAs between 85° and 95°, and 287 (44.6%) showed KFAs between 80° and 85°. A significant correlation was found between KFA and PTD (P < .001), and the intrapatient intraclass correlation coefficient (ICC) was 0.788. A KFA range of 85° to 92° satisfied the criteria of high ICC (0.885) and nonsignificant correlation between KFA and PTD (P = .055) and thus was considered a reliable range of KFAs for quantifying posterior instability. We found no significant risk factors for measurement error, including age (P = .674), sex (P = .328), height (P = .957), weight (P = .248), or body mass index (P = .257). Conclusion: We found high reproducibility of posterior displacement measurements on Telos stress radiography at a KFA of 85° to 92° in noninjured knees.
Descripción del cambio del TEL al TDL en contexto angloparlante

El Trastorno Específico del Lenguaje (TEL) es un trastorno del neurodesarrollo que afecta aproximadamente a un 7% de la población y que compromete a la expresión y/o comprensión del lenguaje oral. Sin embargo, es un trastorno muy desconocido para la población general. Uno de los factores que lo explican es la gran dispersión terminológica que diferentes profesionales y manuales de diagnóstico han utilizado para designarlo. Ante el gran desconocimiento del trastorno y la confusión generada a nivel profesional respecto a la nomenclatura y los criterios diagnósticos Bishop et al. (2016, 2017) llevaron a cabo dos estudios a través del método Delphi en el que participaron diferentes investigadores, profesionales del TEL así como personas de asociaciones de familiares del ámbito angloparlante (consorcio CATALISE). Las principales conclusiones fueron la apuesta por el cambio terminológico hacia el Trastorno del Desarrollo del Lenguaje (TDL) así como unos criterios de diagnósticos que enfatizan en las dificultades funcionales que genera el trastorno y en su pronóstico. En el presente artículo se hace una revisión exhaustiva de todas las implicaciones que los resultados de estos estudios tienen en la conceptualización, la evaluación y la intervención del trastorno. En el ámbito hispanohablante es necesario que se lleve a cabo un trabajo de reflexión y consenso que acuerde la nomenclatura y los criterios de diagnósticos para adaptarlos/ajustarlos al contexto sociocultural y lingüístico de todos los países de habla hispana.
The Attack in Volleyball from the Perspective of Social Network Analysis: Refining Match Analysis through Interconnectivity and Composite of Variables

This study aimed to develop an instrument for analysing the attack in high-level volleyball considering the refined variables adjacent to the attack action, the interconnection between direct and indirect actions, the impact of the previous action, and the formation of composite variables. The game complexes were approached as interacting subsystems. The primary goal was to understand the influence of game actions adjacent to the attack. Three matches of a National Women’s 1st Division 2018/2019 (nine sets, 415 plays) were analysed, considering all game complexes (except attack coverage due to reduced occurrence). An Eigenvector Centrality network with 420 nodes and 7367 edges was created. The networks showed that ideal setting conditions, and strong attacks by the outside and opposite hitters without having received a perfect ball, were central in side-out. In transition, we highlight ideal setting conditions, preferences of the outside hitter, quick attacks in Z4, and high balls in Z2. This study is distinct because it considers different aspects related to the systemic review of the game by using composite variables and the actions prior to the attack. Of these results, we highlight that players attacked with slower tempos for the double action of receive-attack, and these were either preferably directed to the parallel or explored the block. Moreover, for the double defence-attack actions, attackers sought the soft spike in Z2, Z4, and Z8; and when two consecutive individual errors occurred, the players did not err but instead continued to attack to force the opponent’s error.
Environmental drivers of plant distributions at global and regional scales

Editor: Anne Bjorkman Abstract Aim: How environmental factors drive plant distribution across the globe is one of the most fundamental questions in ecology. Nevertheless, the relative importance of different environmental factors in driving plant distributions across spatial scales and among plant groups is not clear. This study aims to disentangle how plant–environment relationships vary with latitude and among plant taxa. Location: Global. Time period: Present day. Main taxa: Plant taxa including angiosperms, gymnosperms, pteridophytes and bryophytes. Methods: We obtained global distribution occurrence data of mass plant groups (625 families, 6,221 genera, and 54,101 species) from the Global Biodiversity Information Facility (GBIF) database. We used random forest method to quantify the relative effects of 15 environmental factors (including climate, soil and topography) on plant distributions at global and regional scales (divided into different latitude zones). We also used phylogenetic generalized least squares (PGLS) models to investigate the relationships between environmental variables and geographical range size, latitudinal range and limits of plants at the global scale. Results: Our analyses revealed the primacy of the effects of climatic variability (temperature seasonality and isothermality) on plant distribution at the global scale. The relative contributions of temperature seasonality and isothermality peaked in tropical areas, whereas solar radiation and annual mean temperature had stronger influence in high-latitude areas. Wide-range plant groups tended to occur in areas with higher temperature variability (isothermality and temperature seasonality) and flatter terrain (low slope). Both climate variability and extreme influenced geographical range size, latitudinal range and limits of plants. Main conclusions: Our study highlights the significance of climate variability for global plant distributions. Environmental effects upon plant distributions vary across latitudes. The findings imply that environmental factors affecting plant distributions change with geographical scales, suggesting that different geographical and ecological processes should be integrated to explain multi-scale distribution patterns.
Technological properties, in vitro starch digestibility and in vivo glycaemic index of bread containing crude malva nut gum

Summary The effects of crude malva nut gum (CMG) on the texture, digestion and the glycaemic index (GI) of white bread were investigated. Different CMG levels (0%, 2.5%, 5%, 7.5% and 10% w/w based on weight of flour) were added into a bread formula. The lightness (L*) and loaf-specific volumes of the bread decreased with increased CMG levels. Firmness of the bread increased with increased CMG content. The in vitro starch digestion kinetics showed that bread containing CMG had generally lower predicted GI (74–81 vs. the control). In vivo human testing showed that increasing the CMG reduced the GI of the bread. The GI values of bread containing CMG ranged from 73 to 98 of the control. Overall liking scores of consumers ranged between ‘like slightly’ and ‘like moderately’ (6.1–7.1) compared to 7.1 for the control. Thus, the addition of CMG in carbohydrate-based foods may lower the GI.
Clinical Fracture of Fiber Reinforced Resin Composite Versus Conventional Resin Composite Restorations in Endodontically Treated Molars: A Randomized Clinical Trial

Background: Short fiber reinforced resin composite (Ever X Posterior) is a bulk fill resin compositeindicated as a core dentine substitute at high stress-bearing areas improve strength and fracture toughness ofconventional resin composite and restored teeth. So, this randomized clinical trial was conducted to validateclinical performance of short fiber reinforced resin composite in endodontically treated molars.Method: 56 participants having endodontically treated lower molars with moderate amount of remainingtooth structure were randomly enrolled in this trial and received either Ever X Posterior covered by Gaenialposterior or only Gaenial posterior resin composite that applied according to manufacturer instructions.Mann-Whitney U test was used for intergroup comparisons and Wilcoxon signed rank test was used forintragroup comparisons. The significance level was set at p ? 0.05. No statistically significant difference wasobserved between both tested groups for all USPHS criteria at different follow-up periods except for colormatch favoring Gaenial posterior with a significant difference between both groups.Conclusion: Both types of restorations showed an acceptable clinical performance along 1 year follow-upperiod.
Optimization of batch Novozym435-catalyzed transesterification of waste cooking oil with methanol for biodiesel production in a solvent-free medium

ABSTRACT In this study, response surface methodology based on face center composite – 1/2 factorial fraction design (FCCD) of experiments was employed to optimize the batch transesterification process of waste cooking oil as one of the most abundant and readily available domestic wastes with methanol using immobilized Candida antarctica lipase (Novozym435) to maximize the production of high-purity biodiesel. Statistically significant second-order quadratic model equations (p < 0.0001) were elucidated through multiple regression analysis to describe the interrelationships between response of interest (biodiesel yield wt% and % conversion, i.e. the transesterification efficiency) and five independent variables (methanol:oil molar ratio, enzyme concentration wt%, reaction temperature °C, reaction time h, and mixing rate rpm). The statistical significance of the effect of these variables (factors) and their interactions on the transesterification efficiency was evaluated and the validity of the predicted models was conﬁrmed. The optimum operating conditions were found to be: 3.63:1 M:O, 8.94 wt% Novozym435, 45.23°C, 2.76 h, and 535.84 rpm. This produced 97 wt% biodiesel yield with % conversion of ≈ 91.79%. An overall acceptable agreement was achieved between the produced biodiesel fuel properties at the aforementioned optimal operating conditions and the Egyptian petrodiesel and international biodiesel standards.
