This paper aims to prepare alkyd protective paint by using modified alkyd with 3,6-dichloro benzo[b]thiophene-2-carbonyl glutamic acid (DCBTGA) as a source of dicarboxylic acid and evaluating their anticorrosive properties compared with those of unmodified alkyd coatings for steel protection.

Short, medium and long oil alkyds, which represented as (0, 10, 20 and 30% excess-OH) according to the resin constants (Patton, 1962), were prepared through a condensation polymerization reaction via a solvent process in a one-step reaction. The modification of alkyd was carried out by using DCBTGA as a source of dicarboxylic acid. The prepared modified alkyd was confirmed by IR and NMR spectral analysis. The physicochemical, mechanical and anticorrosion performance properties of the considered modified coating formulations against unmodified blank coating were studied to confirm their application efficiency.

The best results in terms of physicochemical, mechanical and anticorrosion performance properties were found according to the following of this order activity: 30 replacements of the modifier (DCBTGA) for each hydroxyl continent were 30% Ex-OH > 20% Ex-OH > 10% Ex-OH > 0% Ex-OH, compared with that formulation containing unmodified alkyd, especially with increasing the modifier percent.

The prepared DCBTGA-modified resins can be used for different applications based on the type of alkyd and application.

Since 1966, the Severn crossing has been connecting England and Wales. In January 2018, its ownership returned to the UK Government, and this marked the start of a toll-free journey across the two countries and made commuting between the regions more affordable. In this paper, we examine the impact of the toll removal on the property market.

We employ property-level data from the Land Registry and a difference-in-differences (DiD) empirical model for the periods 2016–2018 and 2019–2021 to capture the pre- and post-toll removal dynamics. The DiD estimation allows us to examine the causal relationship between policy changes and property prices.

Our findings suggest that property prices in Newport and Monmouthshire (South East Wales) are positively affected by the policy, which results in a statistically significant increase of 5.8% more than those located in the South West England (Bristol and South Gloucestershire) region in the period 2019–2021. The impact can reach up to 13.1% for properties located in a 10 km radius of the bridge. The results indicate that the toll removal enables the ripple effect across the two markets by reducing commuting costs.

This is the first paper that examines the Severn Crossing case study. Its contribution is significant since we provide empirical evidence on how reduced transportation costs increase property prices in the lowest income region and have the opposite effect on the area with higher incomes and economic activity levels.

This study aims at discovering the antecedent of halal cosmetics’ purchase intention by conducting development on planned behavioral theory through adding the constructs of word of mouth and religiosity. Attitude plays the role as mediation variable which correlates word of mouth and religiosity toward purchase intention and mediation variable between religiosity and halal cosmetics’ purchase intention.

The sample of this study was 196 Muslim women living in Indonesia. This research was conducted using online survey via google form. The collected data were analyzed using partial least square.

Based on the research findings, word of mouth did not directly influence halal cosmetics’ purchase intention. Religiosity variable also did not directly influence halal cosmetics’ purchase intention. Attitude played the role as the mediation between word of mouth and halal cosmetics’ purchase intention. Attitude was also able to become the mediation between religiosity and halal cosmetics’ purchase intention. Behavioral control and attitude directly influenced halal cosmetics’ purchase intention.

This research findings supported business owners to make sure the cosmetics’ safety for the sake of the users. Halal label is a guarantee that the cosmetics’ process has been through the raw materials selection, the standardized product processing and also the hygienic distribution process.

The literature development of halal products, especially cosmetics, is pretty much needed, as cosmetics users tend to increase throughout the world. Business owners can elevate halal cosmetics’ position through users’ recommendation to increase the economic potential value of halal cosmetics.
