Motivating the formation of partnerships by small water systems

Small community water systems (CWS) often have difficulty maintaining high-quality service provision. Partnerships can help alleviate these problems, yet may not be attainable or pursued. This research examines the perspectives of U.S. state agencies with drinking water primacy regarding the benefits of water systems partnerships and the points of leverage that can induce water systems to partner. It assesses the benefits, drawbacks, and barriers to five common forms of partnerships as well as the approaches states can use to encourage small CWS partnerships. Findings indicate that while partnerships hold significant potential, in many contexts, there are inherent limitations to their formation.

Recruitment of informal caregivers into research studies in community oncology practices: Results from the 2022 NCI Community Oncology Research Program (NCORP) Landscape Committee Assessment.

219 Background: Understanding experiences of community oncology practices in recruiting informal (unpaid/family) caregivers into research studies can inform resources and strategies to improve their enrollment. In this study, we aimed to describe the recruitment of informal caregivers for research studies in community oncology practices. Methods: The 2022 cross-sectional Landscape Assessment of National Cancer Institute Community Oncology Research Program (NCORP) assessed research capacity among network oncology practices. The University of Rochester Cancer Center (URCC) NCORP Research Base used these data to examine factors associated with the recruitment of informal caregivers into research studies in community oncology practices, adjusting for region of the country, practice ownership type, and total number of oncologists in logistic regression analyses. Results: Information was available from 517 discrete practices representing 271 practice groups. After excluding those serving pediatric patients exclusively (n=12) and missing information on recruitment of informal caregivers (n=1), 258 practice groups were included in final analyses. The practice groups had on average 20 oncologists [standard deviation (SD) 28.8]. Over 70% of practice groups (190/258) had advanced practice providers (APPs) involved in clinical research activities. Less than one third of practice groups (30%, 78/258) had experience recruiting informal caregivers of oncology patients for research studies. Informal caregivers were recruited in the following settings: medical oncology (97%, 76/78), radiation oncology (24%, 19/78), survivorship clinic (14%, 11/78), and surgical oncology (10%, 8/78). On multivariable analysis, having a greater number of oncologists [odds ratio (OR) 2.40, 95% Confidence Interval (95% CI) 1.23 - 4.67] and having APPs involved in clinical research activities (OR 2.32, 95% CI 1.13 - 4.76) were positively associated with experience recruiting informal caregivers for research studies. Conclusions: Most community oncology practices did not have experience recruiting informal caregivers of oncology patients, which may reflect limited research in this area. Future research should explore barriers for recruiting informal caregivers into research studies, especially in practices that may have fewer resources such as small community oncology practices or those without APPs involved in research activities.

Diversity distribution, land used type of small and medium-sized mammals in ghamot national park the state biosphere reserve-Neelum, Pakistan

This research aimed to examine the impact of diversity distributions, seasonal variations, and land use types on the richness and diversity of native small mammal communities in Ghamot National Park, Neelum Valley, Azad Jammu and Kashmir, Pakistan. The study employed five different land-use types and employed various methods, including live traps and indirect evidence, to sample small mammals during both summer and winter seasons. The study compared population numbers and species composition across different study sites and seasons.The findings were based on data from three sampling methods, which resulted in a total of 534 specimens representing 14 species from 8 families. The family Muridae stood out as dominant, with 4 species (28.57%) of rodents. During the summer, the highest number of individuals was observed in the forest zone (n = 171), whereas during the winter season, the highest abundance was recorded in the riparian zone (n = 128). In terms of species richness, the riparian zone (n = 9) and agricultural crop zone (n = 9) had the highest values during the summer season. The highest Shannon diversity values (3.48) were found in riparian and forest habitats, scrubland, and dense vegetation, while the lowest biodiversity (H = 0.77) was observed in high alpine pastures and wetland habitats. Notably, no significant differences were observed between the two seasons (summer and winter) in terms of species richness and abundances.Further analysis using a one-way-ANOSIM test via the Bray-Curtis methods indicated a significant difference (R = 0.02144; p = 0.2873) among various survey locations and land types. Specifically, four habitat types—dense forest, riparian zone, scrubland, and dense vegetation—displayed significant correlations with each other (p < 0.05).

Balance of coastal and marine assets for Panggang Island and Semak Daun Island, Kepulauan Seribu DKI Jakarta

Coastal and marine areas hold great wealth for the welfare of coastal and small island communities with dynamic magnitudes. Panggang Island and Semak Daun Island have the potential for promising coastal and marine resource assets and provide benefits for community welfare. The research aims to compile a balance sheet of coastal and marine resource assets for Panggang Island and Semak Daun Island. The research was conducted in the Seribu Islands Administrative District, DKI Jakarta Province, in August-September 2023. It included various information data to map the value of ecosystem services and asset balances. The economic valuation method using the benefits transfer technique is used as input for the value of natural resource assets and the coastal and marine environment. The research results show that the value of coastal and marine resource assets of Panggang Island and Semak Daun Island have quite significant dynamics. In 2014-2019, the coastal and marine resource assets of Panggang Island and Semak Daun Island experienced a considerable decline, namely 1,001.92 billion ( Panggang Island ) and 59.97 billion ( Semak Daun Island ). They decreased respectively by 200.38 billion per year (12.34%) and decreased by 11.99 billion/year (9.29%). The estimation results show that there will be an improvement in asset value in 2022 for Panggang Island to 687.73 billion and for Semak Daun Island to 82.32 billion. The estimation results show that there has been an improvement in the ecosystem during the 2020-2022 period. This increase is due to reduced pressure on coastal and marine ecosystems on the two islands. Ecosystem-based integrated management needs to be carried out so that the sustainability and value of resource assets can benefit the welfare of coastal and small island communities.

Assessing the Awareness and Practices of the Community in Brgy. Cawilan, Tagana-an, Surigao Del Norte towards Solid Waste Management

The problem of solid waste management increases as years pass by. In the Philippines, small communities like Brgy. Cawilan, in the Municipality of Tagana-an, Surigao del Norte have long-term solid waste management problems despite the countless seminars conducted, implemented policies on solid waste management, and key programs to reduce the volume of waste in the community with no landfills and such. Thus, this poses a greater threat to the community’s health and waste disposal. Hence, this study aimed to assess the awareness and practices of the community in Brgy. Cawilan, Tagana-an, Surigao del Norte towards solid waste management. Moreover, this study utilized descriptive-correlation research design employing survey method as a tool in data gathering. The adopted survey questionnaire was floated to the 108 randomly selected residents of Brgy. Cawilan to determine their level of awareness and practices on solid waste management. Results revealed that the level of awareness on solid waste management of Brgy. Cawilan was High, which means that the community are Aware of the solid waste management programs implemented in the barangay. The segregation and reduce practices were Practiced, the reuse practices were Highly Practiced, and the recycle and disposal practices were Less Practiced and lastly the awareness on solid waste management of the community does not affect their practices in terms of disposal but their practices in terms of segregation, reduce, reuse, and recycle influence their awareness on solid waste management. Hence, it is recommended the barangay should reconduct a seminar to reiterate the consequences of violating solid waste management ordinances and to refresh the policies for effective implementation and should have stricter and efficient ways of recycling waste materials to lessen the volume of waste that can be repurposed and schedule collection of waste, provide a centralized disposal areas, and establish a structured landfill disposal to be able to avoid improper waste disposal practices.

Small mammal community composition impacts bank vole (Clethrionomys glareolus) population dynamics and associated seroprevalence of Puumala orthohantavirus.

Rodents are important reservoirs for zoonotic pathogens that cause diseases in humans. Biodiversity is hypothesized to be closely related to pathogen prevalence through multiple direct and indirect pathways. For example, the presence of non-host species can reduce contact rates of the main reservoir host and thus reduce the risk of transmission ("dilution effect"). In addition, an overlap in ecological niches between two species could lead to increased interspecific competition, potentially limiting host densities and reducing density-dependent pathogen transmission processes. In this study, we investigated the relative impact of population-level regulation of direct and indirect drivers of the prevalence of Puumala orthohantavirus (PUUV) in bank voles (Clethrionomys glareolus) during years with high abundance. We compiled data on small mammal community composition from four regions in Germany between 2010 and 2013. Structural equation modeling revealed a strong seasonality in PUUV control mechanisms in bank voles. The abundance of shrews tended to have a negative relationship with host abundance, and host abundance positively influenced PUUV seroprevalence, while at the same time increasing the abundance of competing non-hosts like the wood mouse (Apodemus sylvaticus) and the yellow-necked field mouse (Apodemus flavicollis) were associated with reduced PUUV seroprevalence in the host. These results indicate that for PUUV in bank voles, dilution is associated with increased interspecific competition. Anthropogenic pressures leading to the decline of Apodemus spp. in a specific habitat could lead to the amplification of mechanisms promoting PUUV transmission within the host populations.

Limited effects of azithromycin on the oropharyngeal microbiome in children with CF and early pseudomonas infection

BackgroundTobramycin inhalation solution (TIS) and chronic azithromycin (AZ) have known clinical benefits for children with CF, likely due to antimicrobial and anti-inflammatory activity. The effects of chronic AZ in combination with TIS on the airway microbiome have not been extensively investigated. Oropharyngeal swab samples were collected in the OPTIMIZE multicenter, randomized, placebo-controlled trial examining the addition of AZ to TIS in 198 children with CF and early P. aeruginosa infection. Bacterial small subunit rRNA gene community profiles were determined. The effects of TIS and AZ were assessed on oropharyngeal microbial diversity and composition to uncover whether effects on the bacterial community may be a mechanism of action related to the observed changes in clinical outcomes.ResultsSubstantial changes in bacterial communities (total bacterial load, diversity and relative abundance of specific taxa) were observed by week 3 of TIS treatment for both the AZ and placebo groups. On average, these shifts were due to changes in non-traditional CF taxa that were not sustained at the later study visits (weeks 13 and 26). Bacterial community measures did not differ between the AZ and placebo groups.ConclusionsThis study provides further evidence that the mechanism for AZ’s effect on clinical outcomes is not due solely to action on airway microbial composition.

PROPOSTA DE MELHORIA NO PROCESSO DE PICKING - ESTUDO DE CASO EM UM CENTRO DE DISTRIBUIÇÃO FARMACÊUTICA NA CIDADE DE MANAUS/AM

This article deals with the study of the picking process of a pharmaceutical distribution company located in the city of Manaus/AM, the largest urban centre in the Brazilian Amazon where, due to its geographical characteristics and the need to efficiently serve the capital and the small drugstores located in small communities, it has different characteristics and specificities from other places on the planet. The definition and analysis of performance indicators for a Distribution Centre are topics that are discussed, improved and recurrent, and the performance of the Picking process is one of the main indicators, especially for the case studied, where the company serves. Most of the customers are small businesses that don't have adequate space in their units for storing products and working capital that can be committed to stock. This is the type of customer that predominates in the city of Manaus and the state of Amazonas. This characteristic requires distribution to sort and deliver small quantities with great frequency, thus avoiding a shortage of pharmaceutical products. The aim of this study is to identify the factors that directly influence the drop in the service level of the picking routines. In order to achieve this objective, the Value Stream Mapping quality tool was used, and strategies were then implemented to solve the problems identified in the analysis process. In order to carry out the research during the methodological process, data collection included direct observation of the operation, documentary records from the quality area, such as stock control spreadsheets and performance reports by operators, as well as the use of closed questionnaires for customers and employees. The results and conclusions obtained in relation to the factors that directly influence a drop in the level of service of the picking routines are 05: picking items by stations, thin stock (retail), order consolidation and closing, printing invoices, printing orders, distribution of orders by picking zones. As for defining a methodology for measuring the service level of the picking routines, according to our study, the quality tool that best applies is the VSM. With regard to the opportunities for improvement identified in the processes under analysis, we highlight 05 Improvement in the process of replenishing allocations, Improvement in the addressing of the Flow-rack, Improvement in the information technology infrastructure, Improvement in the technology in the automation process.

What do participants participate in? Insights from the community of Peccioli

ABSTRACT This research is part of a broader study investigating citizen participation in public decisions affecting the present and future of the community of Peccioli, a small village in Tuscany (Italy), through repeated surveys on a random sample of the citizens, and within participatory processes promoted by the local administration. The paper investigates how citizens who participate in one of these processes take part in political, associative and cultural life, and through which channels. The investigation is carried out in a small community, while the vast majority of studies on participation mechanisms so far have concentrated on large urban areas. This contribution presents the findings of a study carried out in 2022 through surveying a random sample of these Peccioli citizens (n = 144). Unlike studies of participatory processes reported in the literature, our study did not rely on the involvement of other public institutions or organized groups but considered ordinary citizens regardless of their potential affiliations. Our research found, firstly, that the respondents were strongly involved in political, social and cultural activities, to a higher extent than reported at national level. Secondly, as expected, their participation in socio-cultural activities was higher than in political activities. Thirdly, even in a small village like Peccioli, the vast majority of participants used a variety of media, particularly digital media, to stay informed and up to date on current affairs.

Deconstruction of Wikipédia Jawa as the Source of Javanese Online Information

This study aims to deconstructed Wikipédia Jawa as a source of reference for Javanese article using Derrida's deconstruction theory. Wikipédia Jawa is one of the Wikipedia projects along with local communities in the world to re-popularize local languages that are empowered for free through internet. This research begins by reading the Wikipédia Jawa website through text which was profided on the page then delays the meaning by searching for the deeper meaning in the website through context and co-text. The hypothesis of this study is Wikipédia Jawa loses its simpleness and easy-to-understand values that cling to ‘Wikipedia’ itself. Wikipédia Jawa as a source of reference for online information in Javanese uses high level of Javanese, Bahasa Jawa Krama, which makes it more difficult for general readers to understand the articles. Furthermore, Wikipédia Jawa only can be consumed by small community which provokes exclusivity of society members.

Outcomes of rural generalist internship training in Victoria, Australia.

Victoria, Australia commenced its first Rural Community Internship Training program in 2012 to support the development of rural generalist (RG) doctors. These general practitioners have additional skills to work at a broad scope to deliver the range of primary care and additional specialist services that communities need. Unlike most internships, which are wholly hospital-based and delivered mostly within larger metropolitan and regional centres, this RG internship training model involves completing general practice experience in smaller rural communities working with RGs and visiting specialists. This study aimed to explore the characteristics and satisfaction of doctors who participate in RG internship training in Victoria and their workforce outcomes. Between October and November 2021, a retrospective 10-minute anonymous survey invitation was sent to all contactable interns (n=222) who had completed/were completing the RG internship training (2012-2021). The survey was co-designed with RG internship managers and other stakeholders of a statewide evaluation advisory group, informed by the latest evidence regarding RG medicine and rural training predictors, and outcomes of interest. Participants completed the survey using Microsoft Forms, with three invitations circulated to an up-to-date email address maintained by the internship program. Collected data were analysed descriptively, by subgroup, to explore training pathway outcomes by region, training stage and specialty choice. Workforce distribution outcomes were defined in line with objectives of the program and predetermined indicators of RG scope. Results were compared with the benchmarks of rural workforce training outcomes in Australia using recent research. There were 59 participants (27% response rate); 81% were in postgraduate years 3-7. Respondents included 54% male, 17% rurally bonded, 39% of rural origin, 34% having had more than 3 months rural undergraduate training and 48% doing RG training where they previously did undergraduate training. All were satisfied/very satisfied with the RG training and 61% were working in general practice (excluding the prevocational group). Overall, 40% were currently working in the same rural region as their internship (including three who were currently interns), 56% continued to complete some prevocational training in the same region as their RG internship, while 20% had gone on to be currently based in smaller rural communities (Modified Monash Model locations 4-7) and 44% to be working part-time in smaller rural communities. Overall, 42% self-identified as working as an RG and nearly all (97%) met at least one of the key indicators of extended (RG) scope. In all areas the RG internship outcomes were better than the national benchmarks from published evidence about rural training. This study provides evidence from doctors up to 9 years after completing their RG internship. Compared with industry benchmarks, the RG internships attract rurally intentioned and rurally experienced doctors who may be likely to remain in the same rural region as their undergraduate rural medical training and continue their postgraduate training in the same region. They were all satisfied with RG internship training, had high propensity to follow a general practice career and work at broad scope in smaller communities. Importantly, they intended to stay in the region where they trained. This suggests RG internship programs are a positive intervention for promoting an RG workforce.

Long-Term Stability of Harvest Mouse Population

The Eurasian harvest mouse (Micromys minutus) is a tiny rodent of the Palearctic and Indomalayan regions, with a distinct regional species status in Europe and irregularly varying local numbers. We analysed the population of M. minutus in Lithuania (Northern Europe) based on trapping data from 1975 to 2022 and owl pellet data from 1986 to 2009. Based on both datasets, the proportion of this species in the small mammal community was similar, 1.13% and 0.62%, respectively. The proportions have remained stable across all decades. Relative abundance was 1.19 ± 0.19 individuals per 1000 trap days, stable over the long term and across the country. Irregular fluctuations in abundance were observed in some of the sites surveyed. The highest average RA was recorded in open sedge habitats, meadows and marshes. The absolute highest RA was 88 individuals per 1000 trap days in floodplain meadows after a major flood. Although the negative impact of habitat anthropogenisation has been confirmed, M. minutus does not require special conservation measures in Lithuania.

Ensuring compliance of physical culture and sports services with quality standards in small and medium-sized territorial communities on the example of Slobozhanshchyna, Dnipro and Zaporizhzhia Regions

The purpose of the article is to investigate the peculiarities of ensuring compliance of physical culture and sports services with quality standards in small and medium-sized territorial communities of Slobozhanshchyna, Dnipro and Zaporizhzhia regions. It was revealed that the management of physical culture and sports takes place on the basis of a developed system of standards, which is characterized by requirements for conducting pedagogical activities with the provision of physical culture and sports services. The need to comply with the standardization of educational requirements for physical culture and sports in territorial communities is explained by the need to improve the quality of provided physical culture and sports services, in particular through the development of special programs to improve the professional qualifications of physical culture teachers in regional sports facilities. The expansion of the powers of the authorities of territorial communities made it possible to develop individual models of the development of physical culture and sports, taking into account the needs of the population of a specific territorial community. Compliance with the requirements in the process of standardization of physical culture and sports provides an opportunity to improve the quality of provided physical culture and sports services in regional sports facilities. The practical significance and prospects for further research are explained by the need to develop and implement new innovative standards in order to improve the quality of provided physical culture and sports facilities in regional sports facilities. The problem of finding opportunities for expanding the powers of territorial communities regarding the quality management of physical culture and sports services, increasing financing of physical culture and sports with the aim of improving the material base and attracting highly professional workers for the training of athletes and the implementation of sports and health activities of the population needs further study.

Proposal of an Agricultural Vulnerability Stochastic Model for the Rural Population of the Northeastern Region of Brazil

Agriculture is the world’s main economic activity. According to the Intergovernmental Panel on Climate Change, this activity is expected to be impacted by drought. In the Northeast region of Brazil (NEB), most agricultural activity is carried out by small rural communities. Local socio-economic data were analyzed using multivariate statistical techniques in this study to determine agricultural sensitivity to drought events (SeA) and agricultural vulnerability to drought extremes (VaED). The climate data used to develop the risk factor (Rdrought) were the drought indicator with the Standard Precipitation Index (SPI) and the average number of drought disasters from 1991 to 2012. Conditional probability theory was applied to determine agricultural vulnerability to drought extremes (VaED). Characterization of the risk of agricultural drought using the proposed methodology showed that the rainy season presents high risk values in the central region, covering areas of the states of Ceará, Piauí, Pernambuco and Rio Grande do Norte, as well as all areas of the semi-arid region. The risk ranged from high to medium. The results also indicated that part of the south of Bahia and the west of Pernambuco have areas of extreme agro-climatic sensitivity. Consequently, these states have an extreme degree of climate vulnerability during the region’s rainy season.

Professional development through CALL lesson study: L2 writing teachers’ perception and practice

Despite a surge of interest in teachers’ purposeful integration of technology into classrooms, research on L2 writing teachers’ digitallymediated writing instruction through lesson study (LS) is essentially lacking. To address this void, we investigated how L2 writing teachers perceived and practices professional development (PD) through technology-assisted writing pedagogy within the three LS phases, i.e., collaborative LS design and implementation, peer observation and feedback, and peer revision. The data sources included the participant teachers’ screencasts, peer reflective comments/responses, and semi-structured interviews. The findings demonstrated that the experience of LS-oriented, digitallymediated writing instruction facilitated the writing teachers’ firsthand exploration of digital spaces and promoted their digitallymediated teaching competence through peer reflection, team coaching, and project-based practices. Additionally, the experience enhanced their pedagogical flexibility, confidence, and autonomy for adapting writing instruction to virtual platforms, assisted them in developing technology-mediated writing lesson plan, task design, and assessment rubric, engaged them in a small community of L2 writing teachers as digital materials co-producers, and helped them use digital tools to meet learners’ context-specific writing needs. The study promises implications for CALL teachers and CALL teacher education programs.

A UVA light-emitting diode microreactor for the photocatalytic degradation of humic acids and the control of disinfection by-products formation potential

Chlorination is one of the most applied technologies for drinking water disinfection. However, the generation of disinfection by-products (DBPs) in the chlorination process is threatening drinking water safety, especially when the concentration of natural organic matter (NOM) is high in source water. Climate change increases the fluctuation of NOM in source water, which further challenges water safety in small and rural communities. In this study, environmental microfluidics was introduced to a UVA-LED photocatalytic oxidation system for a rapid oxidation of NOM. The results showed that HA adsorption and degradation, and DOC degradation were more favored in low pH. At pH 5, 56.9% of HA and 58.1% of dissolved organic carbon (DOC) were removed in 3.4 min by the microreactor. DBP formation potential was efficiently reduced, with the highest reduction of THM and HAA formation potentials by 76% and 70.7%, respectively. Compared with the bottle reactor, the degradation rate constants of HA and DOC by UVA-LED microreactor were increased by 2.99 – 15.8 times, and 6.8 – 170.2 times, respectively. Homogenous irradiation and rapid mass transfer in the microreactor accelerated the inhibited oxidation of HA in acidic and base solutions and increased the apparent quantum yields of photocatalysis. Further, the microfluidic photocatalytic oxidation was much more efficient in the reduction of DPBs formation potential in a source water sample. The process was rapid and had low chemical and energy consumption. Approaches on system scale-up, system simplification, and energy conservation would increase potential of microfluidic photocatalytic oxidation in water purification for households and small communities.

Coastal aquifer water quality for domestic supply of small communities in the semiarid Potiguar - Brazilian Northeast

This study analyzed groundwater quality used to supply small communities in the coastal zone of the Brazilian Northeast, identifying the risks from domestic use of water, and potential contaminants from domestic effluents. We realized analyses of 24 chemical and physical parameters in 15 samples of water from shallow wells. The data was processed through quality modeling, descriptive statistics, principal component analysis, and geoespacialization through kriging. The groundwater used by communities showed some limitations to domestic use. Parameters of Br, hardness, Na+, NO3−, Cl−, SO4−, and turbidity exceed the allowed for Brazilian Health Minister (Ministerial Order n. 888/2021). Furthermore, TDS values present low water quality, predominantly brackish and saltwater, most salinity waters are related to depth and sea proximity. Depth of saturated zone probably is a determinant in nitrate concentrations, comparing the study areas. Water self-supply is considered a risk by health because inferior natural quality of water used and contaminations from domestic sewage determine concentrations of some parameters above of legislation.

Vertical flow wetlands as the core for the sustainable treatment of coffee wastewater in small communities in Colombia: preliminary results of the treatment of coffee wastewater in rural areas by vertical flow wetlands.

Coffee is one of the most important agricultural products in Colombia. To date, small-scale Colombian coffee growers have developed this activity with a simple infrastructure and random use of water that generates harmful by-products to the water resource mainly in the stage of separation of the mucilage. The coffee mucilage wastewater (CMW) is composed of high organic loads and its impact on water sources is due to its high load of nutrients such as nitrogen (N), phosphorus (P), and chemical oxygen demand (COD) values of over 25,000 mg/L. However, there is no consensus on what treatment can be used, especially whether it is accessible to coffee producers. Thus , the aim of this study consisted of assessing the performance of the combination of a carbon filter (CF) as pretreatment and vertical flow wetland (VFW) as a Natural-based Solution (NbS). The results show a reduction of more than 85% of COD, 96% of total solids, and UV254 close to 94%. It was remarkable that both treatments are appropriate for waters with a high concentration of solids. Finally, it can be concluded that CF + VFW is a feasible technology to treat the coffee wastewater from small communities of coffee producers.

Effect of isoindole derivative pigments with planar macroconjugated structure on the UV resistance of HDPE

Different colors of high-density polyethylene (HDPE) natural gas pipelines, water supply pipelines, geomembranes in small communities, garden agriculture, and large factories, play a differentiation, warning, decorative aesthetic, and other aspects of the role. However, little research has been done on HDPE that can be used for long periods and in a variety of colors other than black and white. Phthalocyanine pigments with a large planar conjugate structure are often used in modern artists' paints because of their good stability and are hopeful for use in HDPE. For this reason, in this paper, phthalocyanine blue with a high lightfastness rating was selected. Pure HDPE and HDPE with pigment were compared by color difference, carbonyl index (CI), mechanical properties, and thermomechanical properties before and after UV irradiation. After irradiation for 2000 h, the latter not only did not fade easily but also maintained 82 % elongation at break. At the same time, the carbonyl index was much lower, representing the addition of pigments to inhibit the photo-aging process. Hindered amine light stabilizers (HALS) were also added to the matrix to further improve the ultraviolet (UV) stability along with ultraviolet light absorber (UVA). Addition of HALS and pigments had a positive effect on the UV stability of HDPE, but the excess of HALS had a negative effect on color stability, dispensability and tensile strength. Addition of UVA had little effect on HDPE/Blue/HALS. Finally, the mechanism of the phthalocyanine blue pigment in improving the light aging resistance of HDPE was investigated by ultraviolet spectroscopy. HDPE/Blue/HALS prepared in this work had a low CI and high elongation at break of all formulations at 2000 h of irradiation, indicating that it maintains good performance over a long period of time. The low color change and dispersion uniformity of that under prolonged irradiation met the long-term aesthetic needs of HDPE.
