Evaluating Alexandria University heritage buildings: a question of preservation, awareness and management
Authors: Ezz Eldin Dina , Magdy Heba 
Published: March 2024

PurposeHeritage buildings are a witness to previous civilizations and constitute important elements in transmitting cultural identity through generations. In 1938, Alexandria University was established; it was called the University of Farouk at the time. In 1952, the university was named “Alexandria University,” and since then, it has witnessed growth and expansion in several fields. The research aims to preserve the heritage of this academic institution. It seeks to document this wealth of buildings that tell the story of the second-earliest university in Egypt.Design/methodology/approachA mixed-method approach was employed. A descriptive method was used to narrate the history of the university and the importance of its buildings. Within the quantitative approach, a questionnaire was chosen as the survey instrument for collecting the data within the research case study. The aim was to determine the awareness of students, staff and employees of the heritage importance of their faculty. Within the qualitative approach, several interviews were conducted with employees in the engineering departments of the university administrative building at Chatby and some of the selected faculties. The aim was to determine the methods used for the conservation of these buildings.FindingsAlexandria University has a heritage value not only in its great history but also through its heritage buildings. Raising the awarness of the university's affiliates of this heritage will lead to enhance the feelings of loyalty and belongings to the university. Therefore, preserving this heritage and properly managing it is crucial.Originality/valueUniversities have to recognize that their built heritage constitutes a unique expression that can create a distinctive sense of place. University heritage is crucial in defining and interpreting the university cultural identity. The institution must identify resources that will help build a new public image and contribute to develop a successful brand. Campus appearance is an important factor that has a significant impact on student feelings of loyalty and belonging.
A conceptual cost estimation model for the pre-design stage of road projects using multiple regression analysis
Authors: Atapattu Chinthaka Niroshan , Domingo Niluka , Sutrisna Monty 
Published: March 2024

Purpose
The current estimation practice in construction projects greatly needs upgrading, as there has been no improvement in the cost overrun issue over the past 70 years. The purpose of this research was to develop a new multiple regression analysis (MRA)-based model to forecast the final cost of road projects at the pre-design stage using data from 43 projects in New Zealand (NZ).

Design/methodology/approach
The research used the case study of 43 completed road projects in NZ. Document analysis was conducted to collect data, and statistical tests were used for model development and analysis.

Findings
Eight models were developed, and all models achieved the required F statistics and met the regression assumptions. The models’ mean absolute percentage error (MAPE) was between 21.25% and 22.77%. The model with the lowest MAPE comprised the road length and width, number of bridges, pavement area, cut and fill area, preliminary cost and cost indices change.

Research limitations/implications
The model is based on road projects in NZ. However, it was designed to be able to adapt to other contexts. The findings suggest that the model can be used to improve traditional conceptual estimating methods. Past project data is often stored by the project team but rarely used for analysing and forecasting purposes. This research emphasises that past data can be effectively used to predict the project cost at the pre-design stage with limited information.

Originality/value
No research was conducted to adopt cost modelling techniques into the conceptual estimation practice in the NZ construction industry.

Published: March 2024

Purpose
The current study aims to examine if the internal marketing and employees’ personal traits can predict their green innovative behavior at the workplace.

Design/methodology/approach
A survey was conducted with 683 frontline employees working in four- and five-star hotels in Serbia. Zero-order bivariate correlations among variables and linear multiple regression were conducted to predict green innovative behavior based on internal marketing, personality traits and psychological capital. Binary genetic algorithms were used to segregate the subset of predictors that would be most suitable to describe variance in the outcome.

Findings
The results showed that internal communication, incentive and reward systems, work support, work environment, openness and creative self-efficacy were the most important predictors of almost all the phases of green innovative behavior.

Originality/value
The research showed that a multidimensional approach in analyzing green innovative behavior is necessary as some factors can be significant or not so significant predictors. Acknowledging that innovation is a multistage process, entailing distinct activities and requiring varied individual behaviors to accomplish each task, amplifies the importance of this inquiry. Employees’ personal characteristics have direct impact on green innovative behavior in hospitality. Further, the results gave an insight into the possible mix of elements of internal marketing that can be used for boosting employees’ green innovative behavior in hospitality. This is important as implementing effective internal marketing practices empowers organizations to motivate employees to invest discretionary efforts.
Importance of natural energy, and blue resources to address environmental challenges in view of the Saudi Vision 2030
Authors: Bakoben Hussam Buzaid M. , Khan Mohd Saeed 
Published: March 2024

AbstractThe purpose of this study is to scrutinize the impact of natural resources, energy, and blue economic indicators on the ecological footprint of Saudi Arabia over the period from 1993 to 2022 by employing a nonlinear autoregressive distributed lag model. We have simulated the missing data using the Markov Chain Monte Carlo algorithm. The study encompasses the effects of post‐Vision 2030 and post‐COVID‐19 policies and their assistance in minimizing the environmental footprint. The observed results determine that non‐renewable energy consumption increases the ecological footprint, whereas natural resources and biocapacity drop the ecological footprints in the case of pre‐ and post‐Vision 2030. For variable fisheries production, the post‐ and pre‐Vision 2030 results demonstrate a boosted ecological footprint in Saudi Arabia, with the highest coefficient among all results. This research offers valuable insights into how Saudi Arabia's energy consumption and natural resource management impact its ecological footprint, highlighting the effectiveness of Vision 2030 and post‐COVID policies in promoting environmental sustainability. The study's findings provide crucial guidance for policy making to reduce environmental impact while considering the role of fisheries and biocapacity in ecological balance. Based on empirical findings, this study commends some policy understandings that assist in being effectively implemented towards a sustainable environment.

Published: March 2024

AbstractAlthough the addition of bran to bread makes it healthier and more functional, it brings with it some technological problems. One way to eliminate these problems is hydrothermal pretreatment of wheat bran. In this study, five different ratios (10%, 20%, 30%, 50%, and 100%) of hydrolysates from hydrothermal pretreatment of wheat bran (150°C, 30 min) were substituted with dough‐kneading water during dough kneading for bread making. The physical, chemical, functional, textural and important starch fractions of the bread produced were determined. The addition of hydrolysate in different amounts to the dough‐kneading water resulted in similar physical properties (height, specific volume, and crust color) as the control bread. While the addition of hydrolysate decreased the hardness of the breads, it positively improved important starch fractions (increasing the amount of slowly digestible starch and decreasing the amount of rapidly digestible starch). It also increased antioxidant capacity (iron (III) reducing antioxidant power, ABTS, and DPPH (2,2‐diphenyl‐1‐picrylhydrazyl) and reduced the starch hydrolysis index of the bread. It was shown that the hydrolysate obtained after the hydrothermal treatment of bran could be used in bread making to satisfy the demand for products preferred by consumers from both health and sensory points of view.

AbstractThe impact of high hydrostatic pressure (HHP) on protein digestibility of egg yolk and egg yolk granule was evaluated by static in vitro digestion using the standardized INFOGEST 2.0 method. The degree of hydrolysis (DH) and the phospholipid content were determined during digestion, and the protein and peptide profiles were characterized by sodium dodecyl sulfate‐polyacrylamide gel electrophoresis and reverse phase‐high pressure liquid chromatography (RP‐HPLC). The results showed that HHP induced protein aggregation in egg yolk and granule, mainly by disulfide bridges, which were not disrupted in the oral phase. Proteolysis during the gastric phase improved egg yolk and granule protein solubility, regardless of whether HHP was applied. However, the extent of the samples’ digestibility was not affected, with DH values ranging from 15% to 20%. During the intestinal phase, the DH of egg yolk protein (∼40%) was higher than that of the granule (∼25%), probably due to the denser structure of the granule reducing the accessibility of intestinal enzymes. The DH, peptide, and protein profiles of control and HHP‐treated egg yolk showed similar protein digestion behaviors for both gastric and intestinal phases. Among the different proteins, only the digestibility of β‐phosvitin in HHP‐treated granule was enhanced. Consequently, applying HHP to granules represents an interesting process that improves the digestibility of phosvitin with the potential to generate bioactive phosvitin‐derived phosphopeptides.Practical ApplicationHigh hydrostatic pressure, mainly used as a preservation process, did not impair the nutritional quality of the egg yolk and granule proteins but improved the susceptibility of phosvitin (protein contained in egg yolk) proteolysis to produce bioactive phosphopeptides. Consequently, applying HHP to granules represents an interesting process that improves the digestibility of phosvitin.

AbstractConventional methods for inhibiting browning in wine are not suitable for cili (Roxburgh rose) wine, which is naturally rich in ascorbic acid and subject to restrictions on SO2 addition. In this study, the capacity of various additives to suppress the browning of cili wine caused by ascorbic acid degradation was investigated. SO2, pure reduced glutathione (GSH), regular inactive dry yeast (IDY), and IDY with various levels of glutathione enrichment (g‐IDY) were separately introduced into cili wine following the completion of alcoholic fermentation. Over a period of 12 months, the color parameters, levels of ascorbic acid, phenolic compounds, antioxidant activity, and GSH content of the aged cili wine were analyzed. Among the investigated additives, g‐IDY exhibited the strongest inhibitory effect on browning. Moreover, adding 800 mg L−1 g‐IDY increased the total reducing power and residual GSH content by factors of 1.52 and 2.44, respectively, with respect to those of the SO2‐treated cili wine, thus enhancing its antioxidant capacity. Using ultra‐performance liquid chromatography–tandem mass spectrometry analysis, a total of 22 monomeric phenolic compounds were identified. After g‐IDY treatment, the contents of 15 easily oxidizable o‐diphenols decreased, preventing the depletion of ascorbic acid as an antioxidant. As a result, the levels of ascorbic acid and total phenolics were 1.5‐fold and 1.17‐fold higher than those in the SO2‐treated wine, respectively. This study demonstrates that g‐IDY provides a new approach to preventing the browning of wine caused by ascorbic acid degradation.Practical ApplicationCili wine, characterized by its high ascorbic acid content, can decelerate cellular senescence and bolster immune function, which has contributed to its popularity. Ascorbic acid, a potent antioxidant, can be spiked into white wines to significantly enhance their antioxidative properties. Nevertheless, the high ascorbic acid content in cili wine renders it susceptible to oxidation under both aerobic and anaerobic conditions, which alters the wine's hue from golden to dark brown, thus diminishing its commercial value. Overcoming this browning associated with ascorbic acid degradation is therefore of considerable importance and could facilitate the advancement of the cili industry.

Published: March 2024

AbstractChlorate and hexavalent chromium (chromate) are both widely used in different industries, and the improper waste management in the past left many sites with elevated concentrations in groundwater that pose potential risk to human and/or ecological health. Bioremediation is a sustainable management solution that can reduce both of these contaminants to less toxic species. In our earlier microcosms experiments, we have demonstrated that native microorganisms collected from a site contaminated with chlorate and chromate can lower the concentration of these chemicals in groundwater to acceptable regulatory levels provided sufficient electron donor, nitrogen, and phosphorous are provided. In this study, continuous flow column experiments were performed using soil from the site impacted by both chlorate and chromate in the Province of Manitoba (Canada) and synthetic groundwater amended with acetate, nitrogen, and phosphorous. The objective was to evaluate at a bench scale possibility of in‐situ groundwater treatment. Concentrations of chromate and chlorate measured in the columns' effluent water dropped by 86% and 96%, respectively. However, increased biomass and precipitation of trivalent chromium reduced the water flow rate in the columns, a concern for implementing this method as a long‐term in‐situ remediation solution.

AbstractIntroductionIn China, young men who have sex with men (YMSM) are one of the groups most at risk of HIV/AIDS. The uptake of pre‐exposure prophylaxis (PrEP) among YMSM has not been well documented. A cascade analysis of awareness, willingness, use and adherence with regard to PrEP was conducted separately among YMSM students and non‐students.MethodsFrom 20 October to 30 December 2021, all adolescents aged 16–24 years were selected for the study from among MSM recruited from 31 provincial administrative regions in mainland China. Participants were included in a cross‐sectional study of awareness, willingness, use and adherence with regard to PrEP among YMSM. Logistic regression modelling was used to identify factors associated with the four outcomes.ResultsAmong 1014 student and 866 non‐student YMSMs, respectively, 88.07% and 81.64% had heard of PrEP; 58.16% and 50.35% were willing to use PrEP; 7.59% and 7.62% had used PrEP; and 3.16% and 3.58% had adhered to PrEP. Among students, those living in high‐risk areas and pilot cities and those who had engaged in commercial sex and group sex had a positive effect on PrEP use, and the same trends were found among non‐students living in high‐risk areas and pilot cities and those who had engaged in group sex. ‘Daily oral’ and ‘flexible’ PrEP use positively influenced adherence among both groups.ConclusionsA differentiation strategy of PrEP promotion should be implemented among YMSM. Material support for students, such as financial resources, should increase, while non‐students should increase their level of perception of HIV risk.

SummaryHawthorn fruit and anise seeds are considered medicinal plants. Both have a long history of medical use, which dates back to traditional medicine and has been supported by scientific studies that have demonstrated their effectiveness in many areas. Through pressure‐driven membrane processing, this study describes an environmentally friendly approach to concentrating bioactive compounds in extracts of these plants. Two reverse osmosis membranes (RO‐99 and X‐20) and one nanofiltration membrane (NF‐270) were tested. The composition of initial extracts and the resulting streams (permeates and concentrates) was compared, and the process efficiency was assessed based on the flux profiles and the contents of examined compounds such as antioxidant activity, total phenolic content (TPC) and total flavonoid content (TFC). For the concentration of these extracts, the X‐20 membrane presented the most effective results, showing the lowest overall decrease in permeability. RO99 and NF‐270 followed this. In addition, X‐20 shows the lowest fouling index, followed by RO‐99, and both exhibit reversible contamination. In contrast to the NF‐270 membrane, the contamination was irreversible. Additionally, TPC increased 20 and 18‐fold, respectively, in the final retentate of anise seed extract and hawthorn fruit extract. TFC increased 8‐fold for both extracts compared to the initial content. Furthermore, the process using X‐20 showed an improvement of around 12‐fold for anise extracts, 15‐fold for hawthorn extracts for antioxidant activity by FRAP, and around 9‐fold by the DPPH method for both anise and hawthorn extracts. The phenolic and flavonoids compounds were detected at values <0.4 mg/g in the permeate from X‐20.
Encapsulation of Antarctic krill oil and kaempferol co‐loaded nano‐liposomes in alginate‐chitosan hydrogel beads: improved stability and modified digestive behaviour
Authors: Li Yujie , Liu Guoqin 
Published: March 2024

SummaryIn this study, alginate (NaAlg) and/or chitosan (CS) hydrogel beads were prepared to encapsulate Antarctic krill oil (AKO) and kaempferol (KL) co‐loaded nano‐liposomes. The SEM study confirmed that the hydrogel beads were spherical, in which nano‐liposomes was distributed evenly within the polymer network. The FTIR spectra indicated no evidence of any chemical interaction between nano‐liposomes and hydrogel beads. The hydrogel beads especially the NaAlg‐CS hydrogel beads caused decrease in the release of KL and AKO mostly own to the improved density of bead microstructure. Furthermore, the network structure in the hydrogel beads especially the NaAlg‐CS hydrogel beads successfully insulated oxygen to improve AKO oxidation stability and protected KL by preventing degradation under natural light, while maintaining its antioxidant capacity. Importantly, the hydrogel beads significantly reduced the release of free fatty acids during in vitro digestion compared to nano‐liposomes. In principle, these new delivery systems may combine the benefits of nano‐liposomes and hydrogel beads to encapsulate AKO and KL and broaden their applicability in food industry.

SummaryBrown seaweed is a natural source of fucoidan, a polysaccharide known for its remarkable bioactivities. This study investigated the anti‐obesity effects of fucoidan (Fsar) from Malaysian brown seaweed (Sargassum binderi) using Sprague Dawley rats. The rats were divided into four dietary groups, including normal diet (ND), high‐fat diet (HFD), HFD with orlistat (HFD‐O) and HFD with Fsar (HFD‐F) for 28 days. Results showed a significant (P < 0.05) 36% reduction in body weight gain and an 18% decrease in visceral fat mass in the HFD‐F group compared to the HFD group. Additionally, Fsar treatment also significantly (P < 0.05) reduced insulin (threefold) and leptin (1.3‐fold) levels in blood serum. Improvements in obesity‐related biomarkers by Fsar were observed with a 1.1–1.4‐fold decrease in serum lipid profiles of total cholesterol, triglycerides and low‐density lipoprotein (LDL), without causing kidney or liver toxicity. These findings highlight fucoidan's potential as an anti‐obesity, especially in the food and pharmaceutical industries.
