Abstract
Domestic solid waste management and recycling have been a continuous effort for local authorities. However, recycling activities are still participatory practices in Malaysia. To date, there is no specific law that enforces urban residents to recycle their solid waste. Therefore, this study is intended to investigate recycling facilities (a mechanism) and the urban household’s behaviour towards recycling in Selangor. Shah Alam was selected as the Case Study using six (6) administrative sections (Seksyen 2, 6, 7, 8, 10 and 11) comprising of landed and high-rise housing schemes as the study areas. Research methods included Site Observation, Questionnaire Survey and a Focus Group Discussion (FGD). The questionnaire survey employed the Convenient Random Sampling technique owing to the new norm of the effect of the COVID-19 pandemic. Results demonstrated significant differences in households’ behaviour for residents living in landed properties compared to the high-rise households. The residents are more inclined to recycle when the recycling facilities are closer to their vicinity. This relates very much to the facilities and recycling program delivered by the city council for areas with landed houses and apartments. The study suggested an improvement in domestic solid waste management through proposals put forward by the FGD participants, including the creation of recycling software Applications, enhanced policies and strategies for recycling and further educate the public on the importance of protecting their environment through recycling. The outcome of this study may be a reference to the authority and waste operators in improving their practice for the benefit of Shah Alam’s environment and public well-being.

Abstract
A study was conducted to determine the floristic composition and community structure of trees in lowland dipterocarp forest in Kuala Keniam, Taman Negara, Pahang. This forest is classified as a primary forest and among the oldest rain forest in the world. Five experimental plots with the dimension of 25 m x 20 m each (0.25 ha in total) had been established. The census was carried out for all trees with diameter at breast height (DBH) 5 cm and above. Species composition comprised of 244 individuals from 141 species, 94 genera and 36 families. The total number of taxa is varying across the five plots with the highest total number of families and species recorded in plot 5 with 21 and 43 taxa each. The lowest total number of families and species were recorded in plot 1 with only 14 families and 23 species. Euphorbiaceae is the most speciose family with 20 taxa and 66 individuals followed by Annonaceae with 14 taxa and 19 individuals. These two families are common in the lowland dipterocarp forests in Peninsular Malaysia. Main canopy and understorey and group were recorded with the highest number of species and individuals with 52 and 45 of species and 91 and 75 of individuals, respectively. Pioneer is very rare and was only represented by a single stem of Cratoxylum formosum and Sapium baccatum. Three species, namely Koompassia malaccensis, Elateriospermum tapos and Mallotus leucodermis were represented as the highest total number of individuals for DBH classes of ≥ 5 cm, ≥ 10 cm, ≥ 15 and ≥ 20 cm.

Abstract
3D technology is used in GIS maps to create descriptive graphics that accurately depict the size of real-world items. In a wide variety of various areas, 3D models aid in appearance and survey. For example, 3D maps may depict the height of a building or a mountain in addition to its location. 3D tools must be utilized in conjunction with 2D GIS and then visualized in a 3D environment. The current UPNM campus map accessible to students and staff is not sufficiently helpful and hardly identified its whereabouts. This project was undertaken to develop a web-based 3D campus map and analyze specifically the campus’s area zoning. This study uses a personal computer with Esri CityEngine software to develop the 3D campus map and ArcGIS Online to publish the web-based 3D campus map. The data was acquired by downloading the base map of UPNM from OpenStreetMap (OSM). Completion of data processing results in a web-based 3D UPNM campus map with area zoning. The finding shows that the 3D map, using the Geographical Information System (GIS) platform, is more informative and attractive than the 2D map due to the attribute and spatial data. In addition, the capabilities of the 3D map to visualize and show the campus area and area zoning in the map can be managed according to the structural information. All in all, it can be concluded that this web-based 3D map contributes towards the sustainability of the UPNM infrastructure and campus while facilitating campus maintenance and rehabilitation.

Abstract
A study was conducted to determine the composition of wild fruit tree in Kuala Keniam, Taman Negara (National Park) Pahang. A method of field specimen collection was used in this study. Five plots of 0.05ha (25 m x 20 m) were established. Trees of ≥ 1 cm diameter at breast height (dbh) were measured within the plot. Additional data was also obtained from a general survey around the forest trails. A total of 41 species from 19 genera and 11 families of wild fruit trees were recorded. Guttiferae was listed the highest with 10 species (24.4%). It was followed by Euphorbiaceae and Sapindaceae with seven species (17.1%). Genus-wise, Garcinia has recorded the highest total number of species with 10 species followed by Baccaurea (six species), and Artocarpus (four species). The low total number of species in this study is due to the limitation time for sampling. A detailed study on the composition of fruit trees in the plot is needed in the future to get more information on the importance of wild fruit trees in Kuala Keniam in Taman Negara Pahang.

Abstract
Malaysia is on track to become an aged nation by 2030, with older people accounting for 15% of the total population. Changes in a country’s demographic composition of older people have a significant socioeconomic impact, given that medical and long-term care services account for the majority of government spending. Promoting an active and healthy lifestyle among older people has become critical to their ability to live independently. Social participation among older persons is one way to encourage active ageing. The purpose of this study was to learn more about older people’s preferred social activities to better understand their preferences to promote sustainable cities and communities (SDG 11). A qualitative research approach was used in the study by using a semi-structured interview with a total of 41 older persons. Three states including Penang, Selangor and Kuala Lumpur were selected as the main location to reach the targeted participants in the study. All the older participants were selected based on the inclusion criteria including; (1) older persons aged 60 years and above; (2) older persons who participated in the social activities; (3) activities centres located at three urban areas including Penang, Kuala Lumpur and Selangor. The findings of the study found five (5) types of preferred activities among older persons: (1) Leisure learning activities; (2) Religious activities; (3) Community-related activities; (4) Home-based activities; and (5) Job-related activities. In conclusion, there is an apparent need to provide aged–friendly areas and create a good built environment to assist the older persons, in keeping with the national agenda to achieve aged nation status and achieve the SDGs.

Published: May 2022

Abstract
A highly selective and sensitive assay of Al(III) using ratiometric fluorescence enhancement is reported in an aqueous solution. The probe (named RS5) exhibits a red-shift of 54 nm upon binding with Al(III) ion. The significant enhancement response of RS5 at 481 nm is attributed to the formation of a 1:1 complex between the probe and Al(III), wherein RS5 acts as a tridentate NNN-donor ligand. The complexation process is ascertained by 1H, 13C, and 27Al NMR and HR-MS spectral techniques. The binding constant of the complex is determined to be 1.3 × 105 M−1. The ratiometric change in fluorescence upon complexation with Al(III) is ascribed to an increase in intramolecular charge transfer (ICT) transition along with chelation enhanced fluorescence (CHEF) processes. The probe can be applied for monitoring Al(III) in a pH range of 6–8. The limit of detection (LOD) of RS5 for the examination of Al(III) is found to be 0.3 μM. With an aim to understand the sensing behavior of RS5, the optical properties of the probe and its Al(III) complex are investigated using density functional theory (DFT) and time-dependent density functional theory (TD-DFT) methods. The probe is successfully employed for the determination of Al(III), with very high recovery percentages, in natural matrices like deep well water, tap water, drinking water, pond water, river water, bovine serum albumin (BSA) solution and blood serum.

Published: May 2022

Abstract
We report here the development of a surface-modified quartz glass sheet, which affords an opportunity for converting conventional spectrofluorometers to ion-selective optochemical sensors by placing it diagonally into a photometric cuvette. Moreover, we describe a generalizable technique, which allows the usage of any polymerizable ionophores for developing multiple-use fluorescent chemosensors of various selectivity. A fluorescent bis(acridino)-crown ether containing allyl groups was photocatalytically copolymerized with a methacrylate-acrylamide-based monomer mixture to obtain an ion-selective sensor membrane layer on the surface of the cuvette-compatible glass sheet. This glass membrane-based direct optode enabled the analysis of Zn2+ above a lower limit of detection of 2.2 × 10–7 mol·l−1 with an excellent reusability. Limiting factors, like pH and competing ionic or organic agents were thoroughly investigated. Moreover, spiked river-water samples were measured to demonstrate applicability. The proposed sensor placed in any conventional spectrofluorometer provides an innovative method for perturbation-free analysis of Zn2+ for all the chemists in need of a fast, easy-to-use, portable and regenerable analyzer without the requirement of an analyte-specific instrumentation.
Microstructure and mechanical properties of TLP-bonded 9CrMoCoB heat-resistant steel with Ni–Cr–B interlayer

Published: May 2022

Abstract
9CrMoCoB heat-resistant steel was transient liquid phase (TLP) bonded by using a Ni–Cr–B amorphous filler metal. Results indicated that the TLP-bonded joint was composed of three feature regions, and the precipitates in the diffusion affected zone (DAZ) were M23(C,B)6-type carboborides and M3B2-type borides with different morphologies and locations. Fine granular Fe2Mo-type Laves phases and MX-type carbides that existed in the original base metal were found in the grain. The carboborides and borides in the DAZ that grew with the increase in bonding time and temperature were reduced or completely dissolved after post weld heat treatment (PWHT). The joints without PWHT showed high strength and low elongation due to the high hardness and high hardenability of the matrix. The initiation of cracks occurred on borides in the athermal solidification zone and carboborides in the Ni-DAZ and passed through in the bonded seam, resulting in the reduction in the tensile strength of the bonded joints. The hardness of the joints was obviously reduced, and their toughness was obviously improved after PWHT. The highest tensile strength reached to 744 MPa when the TLP joints were bonded at 1150 °C for 30 min, which was comparable with the original base metal.

Irrigating urban green space for cooling benefits: the mechanisms and management considerations
Authors: Cheung Pui Kwan , Nice Kerry A , Livesley Stephen J 
Published: May 2022

Abstract
Evapotranspiration is an important cooling mechanism in urban green space (UGS). Irrigating vegetated surfaces with potable water, collected stormwater or recycled sewage water has the potential to increase the cooling effect of UGS by increasing evapotranspiration. Such cooling effect may not always be strong because evapotranspiration is dependent on local and regional factors such as background climate, seasonality and vegetation type. When using irrigation for cooling, city managers also need to consider management issues such as irrigation water supply and amenity use of the UGS. This study aims to develop a theoretical framework that explains the physical and energetic mechanisms of irrigation cooling effect and a framework to assist city managers to make decision about the use of irrigation for urban cooling. This is achieved by reviewing the impacts of irrigation on local climate reported in the literature and identifying the regional and local factors that influence irrigation cooling effect in warm seasons. The literature suggests that irrigation can potentially reduce daily maximum air temperature and ground surface temperature by approximately 2.5 °C and 4.9 °C, respectively, depending on weather conditions and irrigation amount. Background climate is an important factor that influences the cooling potentials of irrigation. Cities with dry and warm climates have the highest cooling potentials from irrigation. The cooling potentials are also influenced by seasonality and weather, vegetation type, irrigation time of day and irrigation amount. Cities with a dry and warm season can consider using irrigation to mitigate urban heat within UGS because such climatic conditions can increase cooling potentials. To maximise irrigation cooling effect, cities with abundant irrigation water supply can use a soil moisture-controlled irrigation regime while those with limited supply can use a temperature-controlled regime. More studies are required to understand the cooling potentials of irrigating small, individual UGS.
Discovering gene regulatory networks of multiple phenotypic groups using dynamic Bayesian networks
Authors: Suter Polina , Kuipers Jack , Beerenwinkel Niko 
Published: May 2022

Abstract
Dynamic Bayesian networks (DBNs) can be used for the discovery of gene regulatory networks (GRNs) from time series gene expression data. Here, we suggest a strategy for learning DBNs from gene expression data by employing a Bayesian approach that is scalable to large networks and is targeted at learning models with high predictive accuracy. Our framework can be used to learn DBNs for multiple groups of samples and highlight differences and similarities in their GRNs. We learn these DBN models based on different structural and parametric assumptions and select the optimal model based on the cross-validated predictive accuracy. We show in simulation studies that our approach is better equipped to prevent overfitting than techniques used in previous studies. We applied the proposed DBN-based approach to two time series transcriptomic datasets from the Gene Expression Omnibus database, each comprising data from distinct phenotypic groups of the same tissue type. In the first case, we used DBNs to characterize responders and non-responders to anti-cancer therapy. In the second case, we compared normal to tumor cells of colorectal tissue. The classification accuracy reached by the DBN-based classifier for both datasets was higher than reported previously. For the colorectal cancer dataset, our analysis suggested that GRNs for cancer and normal tissues have a lot of differences, which are most pronounced in the neighborhoods of oncogenes and known cancer tissue markers. The identified differences in gene networks of cancer and normal cells may be used for the discovery of targeted therapies.
Art Training and Artistic Efficacy as Predictors of Volunteerism in Elders

Published: May 2022

Abstract
Facilitating elders’ volunteerism, which comprises motivation and practice to help people formally, is beneficial to the elders and their volunteering beneficiaries. According to social–cognitive theory, such facilitation supposedly benefits from art training to raise elders’ artistic efficacy. This study examines such a supposition with a two-wave panel survey of 118 elders in Hong Kong, China. Among them, forty-seven were art trainees in a senior centre and seventy-one were non-trainees. Results show that art training significantly contributed to Waves 1 and 2 artistic efficacy and volunteerism in the elder. Moreover, Wave 1 artistic efficacy significantly contributed to Wave 2 volunteerism. The results imply that art training aiming to raise artistic efficacy in a senior centre is valuable for facilitating elders’ volunteerism. Incorporating such training in social services is thus worthwhile.
