Plantings surrounding kindergartens are an integral part of urban green spaces. These open areas play a very important role in the lives of children, in their development, their eating habits, and environmental awareness. For this reason, it is extremely important to select adequate plant species, which are not dangerous for the children. There are 10 public and 9 private preschool institutions in the entire area of the two Novi Zagreb (East and West) city districts. Only public kindergartens have been included in this research. The aim was to determine the size of green open space surrounding public kindergartens, analyse woody plants on site, determine the taxonomic affiliation of plant species, and detect the presence of poisonous and allergenic plant taxa. In green space surrounding kindergartens in the Novi Zagreb – East city district, 49 taxa of trees, and 18 taxa of shrubs and woody climbers from a total of 22 plant families have been identified. Similary, in the Novi Zagreb – West city district, 49 taxa of trees, and 24 taxa of shrubs and woody climbers from a total of 26 plant families have been determined in kindergarten plantings. A total of 32 poisonous taxa, and 36 allergenic taxa have been catalogued in the Novi Zagreb – East city district, while a total of 34 poisonous taxa, and 42 allergenic taxa have been listed in the Novi Zagreb – West city district. The most poisonous species were: Taxus baccata, Prunus laurocerasus and Sambucus nigra. The species with the highest allergenic potential were: Thuja occidentalis, Betula pendula and Acer platanoides.

Modelling the atmospheric dispersion of ammonia in an industrial area in northern Greece

Air pollution is one of the greatest challenges for ecosystems globally, as it adversely affects not only human health, but also water resources, land, animals and plants. The composition of atmospheric air is changing due to urbanization, industry, land surface alteration, climate change and global population increase. Studying the dispersion of atmospheric pollutants is a crucial issue for better urban, regional and global predictions of air quality. Dispersion models have proven a valuable tool in estimating the concentration of air pollutants produced by industrial facilities, as well as predicting future concentrations under specific scenarios (e.g., changes in emission sources or emission rates). The objective of this research was to examine a number of hypothetical industrial accident scenarios, including the local spread of ammonia from an industrial zone located 5 km east of the coastal city of Kavala in northern Greece. For that, the Atmospheric Dispersion Modeling System 5 (ADMS-5) was used as a safety and emergency planning tool, in order to model instantaneous releases (puffs) of ammonia and to investigate changes in ground-level concentration. To determine the structure of the atmospheric boundary layer, seven different meteorological conditions which correspond to the Pasquill-Gifford stability categories A-G were considered. The maximum ground-level concentration (1400 - 2400 μg/m3) occurred in slightly stable and moderately stable conditions (categories E and F) very close to the source, while in extremely stable conditions (category G) the puff remained stagnant for over 600 s after release. The lowest ground-level concentration (300 μg/m3) occurred with slightly unstable conditions (category C). The obtained results can be used for safety and emergency planning reasons and highlight the importance of atmospheric stability on the fate of accidental industrial releases.

Seismicity of the Southern Marmara Region (Türkiye) before and after the August 17, 1999 İzmit earthquake

In the present study seismicity of the Southern Marmara Region before and after the 1999 İzmit earthquake are analyzed and compared. A homogeneous seismicity catalogue that have completeness above the MC=2.9 and covers the time period between 1978 and 2020 is used. Comparison of the spatial mapping of the frequency-magnitude distribution before and after the 1999 İzmit earthquake revealed that b-values demonstrate a general increase after the earthquake indicating a general stress decrease in the region. The shortest computed TL value of about 450 years in the east of city of Bursa vanished after the 1999 earthquake. The computed time variations of b-value have shown an increase from 0.8 to 1.6 between 1978 and 1997 and an anomalous increase from 1.1 to 2.1 between 2000 and 2006. After 2006, b-values have decreased from 2.1 to 0.8, implying that decreased stress after the 1999 İzmit earthquake begun to increase after that year.

This study includes picking seven reflectors from intense sampling of 3D Seismic survey composed of 40 inlines and 30 crosslines, the distance between the seismic lines is equal to 250m. The study deals with extracting and analysing volume seismic attributes of 3D seismic data of Chia Surkh area. The area is located east of Kalar City, Sulaimani Government, Kurdistan Region, Iraq. The main aim is to determine locations of hydrocarbon accumulation by picking seven horizons as well as studying and analysing both subsurface structure and direct hydrocarbon indicators. The seismic volume attributes are calculated from the original seismic data that consist of (400) inlines and (300) crosslines, and the distance between two adjacent lines is equal to (25m). The seismic attributes used in the current study are, variance edge, curvature, root mean square, envelope and sweetness. Revealed existence of a major anticline, a major fault. As well as two small faults were detected and running parallel to the major fault, while the envelope and sweetness attributes emphasized appearance of several bright spots within Lower Fars, Dhiban, Jeribe and Euphrates Formations, which give quite evidence for accumulation of hydrocarbon. The study concluded that the complete system requires for existence of petroleum is available such as the major anticlinal structure, carbonate rocks as an excellent reservoir rocks and gypsum or (anhydrite) as an optimal cap rock. The existence of hydrocarbon is confirmed by bright spots.

Adsorption and physicochemical release of iron ions in soils with different content of Calcium Carbonate and Calcium Sulfate

Three soils of different content of gypsum and lime were selected, the first soil (G1) and the second soil (G3), were obtained near the fields of the Faculty of Agriculture, Tikrit University. As for the third soil (G5), was taken from the AL- alam Village side east of Tikrit city to a depth of (0-10)cm. the proportions of gypsum were 5%, 15%, 25%, and the proportions of lime were 25%, 20%, and 10% for soils G1, G3, and G5, respectively. Ferrous sulfate was added as a source of iron ions added to the three soils in the following proportions (0,10,25,50,100,150,250,500,750) mg.L-1 The concepts of isotherm were tested by using the physicochemical Freundlich and Langmuir adsorption equations. The results of the study showed the success of both equations in describing of iron ion adsorption process for all three soils, because They achieve a high (R2) but Langmuir's equation showed a greater superiority due to its decreasing (SE). As it appears from the results of the study, the superiority of treatment (G1) over treatments (G3) and (G5) in the maximum adsorption values, binding energy, (PBCFe)(KG) and (Kd) for adsorption and release. As for the values of Labale iron, the lowest value was in treatment (G1)then it began to increase until it reached its value in treatment (G5). The (Δf) values for the three soils were positive, and that the highest value was in soil (G1), and starts declining to reach its value for soil (G5).

Solving Temporary Housing Problem by Using Cooperative Grey Games after a Collapse of Sirte-Jufra Line

This paper showed that the cooperative grey game theory can help us to establish a fair cost share among private organizations for supporting the temporary housing problem by using facility location games under uncertainty. Temporary accommodation may be a method that ought to get started before the tragedy happens, as a preventative pre-planning. Although they are temporary constructions, the housing buildings are among the most important parts to be built for emergencies, to contribute to the reconstruction and to recover better.The study was based on a default disaster in the Sirte-Jufra line in the middle of Libya. A number of emergency temporary houses are being built in the following three cities, Ajdabiya, Al-Marj, and Benghazi east of Sirte city as illustrated in Figure 1. Three companies were selected, two of them are locals and a third is foreign to distribute the emergency houses in a fair way among the three cities. For this purpose, we use the cooperative grey game theory to help us define a fair cost allocation among private organizations for supporting the housing problem by using facility location games under uncertainty.

Harmonization of Epidemiologic Research Methods to Address the Environmental and Social Determinants of Urban Slum Health Challenges in Sub-Saharan Africa.

Sub-Saharan Africa (SSA) has a significant proportion of populations living in urban slum conditions, where exposure to multiple environmental stressors and social inequalities is ubiquitous. This commentary synthesizes commonalities in recent environmental health studies from urban cities in East and West Africa, presented during a symposium sponsored by the Africa Chapter of the International Society of Environmental Epidemiology (ISEE) in August 2020. A key takeaway from this symposium is the need for harmonization of epidemiologic and exposure data collection in three domains tailored to the SSA context: (1) improvements in socioeconomic status (SES) measurement through harmonization in the conceptualization and operationalization of SES indicators; (2) improvements in air pollution exposure assessment in resource-constrained contexts by better integration, validation, and harmonization of exposure data of air pollution and mitigating factors; and (3) harmonization in the assessment of health outcomes and biomonitoring of contaminants. Focusing on these three domains would galvanize environmental epidemiologists in SSA around shared data collection instruments and shared data platforms and facilitate the pooling of data across the continent. Fostering this collaborative research will enable researchers and decision-makers to glean new insights and develop robust environmental health interventions and policies for SSA urban slums and for improved population health.

Comprehensive chemical characterization of PM2.5 in the large East Mediterranean-Middle East city of Beirut, Lebanon

The chemical composition of PM2.5 at two sites in Lebanon, a country in the East Mediterranean - Middle East region, is investigated in the spring and summer seasons. The average PM2.5 concentrations were of (29 ± 16) µg/m3 for Beirut urban site and (32 ± 14) µg/m3 for Beirut suburban site. This study showed that the geographic location of the East Mediterranean region, such as its proximity to the Mediterranean Sea and the dust storm intrusion are a significant contributor to the high PM levels from natural sources, which cannot be mitigated, rendering the PM2.5 WHO annual Air Quality guideline unattainable due to high natural background, which also applies to the entire Middle East region. Turkey and Eastern Europe are the dominant origin of air masses throughout our sampling days, suggesting the long-range transport as an important potential contributor to the high observed concentrations of V, Ni, and sulfate in this region most probably in other East Mediterranean countries than Lebanon too. Main local sources determined through the chemical speciation including organics are road transport, resuspension of dust and diesel private generators. A health risk assessment of airborne metals was performed and the carcinogenic risk for all the metals exceeded by 42 (adults) and 14 (children) times the acceptable risk level (10−6) at both sites. Vanadium was the predominant carcinogenic metal, emphasizing the need to replace energy production with cleaner energy on a regional level and highlighting the severe impact of air pollution on the health of inhabitants in this region's main cities.

PUBLIC SPACES, VALUES, AND NEEDS

While cities are expanding, public space is retiring worldwide. In recent decades many Middle East cities have undergone massive transformations; however, the quality of public spaces of the new globalized cities has been often neglected, although new needs and new ways of living are currently searching for new typologies of public spaces. Particularly in Lebanon, in 1990, after fifteen years of war, the Government developed an urban reconstruction plan to rebuild downtown Beirut, completely destroyed. The plan promoted the idea of building a new contemporary Beirut as the capital of the Middle East, a new city with towers, malls, commercial areas, without considering the life quality of Lebanese citizens and their social needs of new public spaces. The main research problem is the claimed need for public spaces from Lebanon's inhabitants that are currently unavailable. The paper's main aim is to promote the values of social places that can help address pressing challenges like social segregation and equity and urban regeneration processes that affect the population's life. Additionally, public space has enormous potential by strategically supporting cities' economic, environmental, and social agendas. The research methodology has been developed by conducting a series of interviews and a literature survey about the need and values of public spaces in Lebanon. The research has highlighted the transforming needs and values of public spaces that follow the transformation of Lebanese society. The research has identified some typologies of spaces currently required to improve the built environment's quality and promote higher living standards.

The life forms of the collected species were 62 (72%) where Hemicryptophyte were dominant, 33 (22%) Therophytes, 14 (9%) Chaemophyte, 42 (27%) Phanerophyte and Geophytes were 4 (2%). The breakup of the habit categories shows that the herbs with 103 (66%) species were dominant to show the flora of the study area, followed by shrubs with 17 (10%) species which shows the flora of the study area. Subshrubs by 9 (6%) and trees 27 (22%) contained the flora of the study area. We studied three stands and in each stand, we placed twenty quadrate to recognize the dominant flora based on IVI. We recognized the dominant lifeform Hemicryptophytes and dominant taxa Thaymus linearis held at the highest value (64.259) based on IVI. The phytosociological studies provided all required information from each stand like dominant habit categories, dominant life forms, and dominant taxa in the study area.

Research on entropy weight multiple criteria decision‐making evaluation of metro network vulnerability

AbstractWhen the subway network system has insufficient resilience and strong vulnerability, the network operation function will be greatly attenuated or even lost due to the failure of key nodes or lines. Evaluating the vulnerability of the metro network is one of the keys to prevent and control risks. This paper proposes an entropy weight multiple criteria decision‐making evaluation method that combines the vulnerability indexes of agglomeration, network efficiency, and network traffic with the multiple criteria decision‐making method, classifies the vulnerability of subway stations with a clustering idea, and analyzes the most vulnerable area of the Beijing Metro network with the Newman fast algorithm. The results show that this method can evaluate the node vulnerability of metro networks more accurately and effectively by considering the topological vulnerability, functional vulnerability, and human flow function vulnerability of the networks. According to the node vulnerability value, the stations can be divided into five grades: The station at the intersection of the loop and radial lines and its adjacent stations have a higher vulnerability level. The vulnerability level of the downtown core area and suburban line terminal stations is relatively low, and the areas with the greatest vulnerability of the Beijing Metro network are mainly located on the east and west sides of the core city.

Design and evaluation of maternal early warning system to reduce preventable maternal mortality in pregnancy and puerperium for high-risk women in China

BackgroundThe maternal early warning system is an effective tool to reduce maternal mortality and morbidity. However, there has been limited research on developing a maternal early warning system especially suitable for Chinese high-risk pregnant women. ObjectiveThe purpose is to develop a maternal early warning system to reduce preventable maternal mortality in pregnancy and puerperium in high-risk women in China. DesignA cross-sectional survey design. SettingThe study was conducted in a first-level hospital in China. ParticipantsA total of 306 pregnant women were selected as the objects who were admitted to give birth from April to June 2021 in xxx. MethodsA convenience sampling method was used to select 42 experts from 20 hospitals in more than 10 cities in east and west China, which represents the developed and undeveloped cities. The maternal early warning indicators of high-risk pregnancy during pregnancy and after birth were determined via literature research, research group discussion, and the Delphi expert consultation. Measurements and findingsThe final maternal early warning system for high-risk women in pregnancy and puerperium included 8 first-level indicators and 30 second-level indicators. The expert authority coefficients of the two rounds of consultation were 0.92 and 0.94, respectively. The Kendall harmony coefficients were 0.252 and 0.386, respectively (P<0.001). The area under the ROC curve predicted by the early warning system for high-risk pregnancy during childbirth was higher than 0.86, and the best cut-off point was 9.97. It was statistically significant (P<0.001). Key conclusionsThe constructed maternal early warning system for high-risk pregnancy in pregnancy and puerperium has comprehensive contents and high reliability, which will help midwives to identify high-risk pregnancies during childbirth. Implications for practiceThe results of this study can help to detect deterioration of the patient, predict morbidity in high-risk women and enable timely intervene to prevent possible severe illness.

An integrated hydrological and hydraulic modelling approach for flash flood hazard assessment in eastern Makkah city, Saudi Arabia

Flash floods are among the most destructive natural disasters with associated adverse impacts on society and the environment. The present study assesses the adverse impacts of flash floods within the Wadi Mehassar basin on the holy sites (i.e., Al Mashaaer Al Muqaddassa) and urban areas, east of Makkah city, which are highly vulnerable to flash floods especially during short duration high intensity rainfall. The difficulty associated with assessing the flash flood hazards in the study area is attributed to the rapid alterations in topography with accelerated urban development and the lack of hydrometric stations to gauge the surface runoff. Thus, in order to achieve the goals of the study, The ArcGIS 10.4, ERDAS Imagine 2015, and the Watershed Modelling System WMS 11.0 were used to process geological and hydrological data and prepare the modelling inputs such as geological, metrological and hydrological groups of the drainage basins under examination. Moreover, a mathematical hydrologic model (HEC-1), was applied to produce the hydrograph curves of the Wadi Mehassar basin, based on the synthetic unit hydrograph of the Soil Conservation Service (SCS-UH). The two-dimensional hydraulic modelling (HEC-RAS 5.0.7) software was employed, to calculate and simulate the water surface elevations, flow velocities, flow depths and spread of the flash flood, in order to develop the hazard rating map of flash flood inundation. The model results identified 44% of total area as liable to flash floods, and out of which 5.4% indicated high risk, 13.3% showed medium risk and the remaining 81.3% area fell under low risk of flash flooding.

There is small change in the pH value during the observation period among upstream, basin and downstream. Different genera of algae found in Degala basin.

Passionately attached or properly matched? The effect of self-congruence on grocery store loyalty

PurposeFresh products' homogeneity makes it difficult for grocery stores to differentiate themselves by improving product or service quality. This study analysed grocery store loyalty from the perspective of self-congruence and compared the relative importance of affective attachment and lifestyle matching, which acts as a mediating mechanism in influencing customer loyalty.Design/methodology/approachIndividuals in Shanghai, Guangzhou, Chengdu, Beijing and Xi'an; representative cities of China's east, south, west, north and central regions, responded to questionnaires. Altogether, 282 valid responses were obtained; structural equation modelling (SEM) was used to test the hypotheses.FindingsThe findings show that lifestyle congruence has a greater mediating effect than emotional attachment in the relationship between store-self congruence and grocery store loyalty. Furthermore, social self-congruence was the dominant dimension of store-self congruence that affects grocery store loyalty.Research limitations/implicationsThe first important academic contribution of this study is the provision of knowledge on the issue of whether to focus on generating grocery store loyalty via the mediating effect of emotional attachment or lifestyle congruence. Furthermore, the empirical findings further clarify the boundary of brand attachment theory, demonstrating the limitation of this theory in explaining the mediating mechanism for self-congruence on loyalty in a context that sells low-involvement products in a collectivistic culture. Another academic contribution focuses on the examination of dominant dimensions of self-congruence.Practical implicationsThis study provides a new strategy for grocery store managers to avoid the trap of homogeneous competition, namely, to clearly define consumers' social rather than personal identity. Additionally, grocery stores should focus on matching their image with target customers' lifestyles when building customer loyalty.Social implicationsThis study's findings also shed light on public policy. Some implications could be increasing the layout rationality of retail commercial outlets to facilitate the interaction between grocery stores and community consumers and promoting the matching of grocery stores and consumer lifestyles. Such policies may boost grocery sales, which in turn would boost farmers' incomes.Originality/valueCompared to previous studies, this study analysed the customer loyalty of grocery stores from the perspective of self-congruence, analysed the mechanisms by which self-congruence influences customer loyalty via the mediating effects of emotional attachment and lifestyle congruence and compared the relative significance of these two paths. Furthermore, this study clarified the relative importance of self-congruence dimensions in influencing grocery store loyalty.

Health risks of inhalation exposure to BTEX in a municipal wastewater treatment plant in Middle East city: Shiraz, Iran.

Benzene, toluene, ethylbenzene, and xylene, known as BTEX, adversely affect human health. This study aimed to measure BTEX concentration and assess the health risk through inhalation exposure to these compounds in a municipal wastewater treatment plant. The ambient air samples were collected using the active sampling method in summer and winter. Sampling sites were close to wastewater treatment units, including bar screen & grit chamber (Site-1), aeration tank & secondary clarifiers (Site-2), anaerobic sludge digester (Site-3), and office & control building (Site-4). Results indicate that the mean levels of benzene and toluene in winter were higher than in summer. The levels of benzene and toluene were below the occupational exposure levels of the American Conference of Governmental Industrial Hygienists (ACGIH) and Occupational Safety and Health Administration (OSHA). The carcinogenic risk (CR) and hazard quotient (HQ) were assessed using the United States Environmental Protection Agency (U.S.EPA) method, and Monte Carlo simulation (MCS) was applied to quantify the uncertainty and sensitivity analysis. The CRs for all sampling sites were below the U.S.EPA threshold limit (1.0×10-4). The HQ values for benzene nearby Site-2 were above 1.0, indicating inhalation exposure could pose a health hazard. Besides, the HQ results for exposure to toluene in all sampling sites were less than 1.0. The sensitivity analysis had shown that the risk determinant for carcinogenic and non-carcinogenic risk was exposure time, followed by concentration.

Land Surface Temperature and its Relationship to Population Density

Population density due to urbanization contributes to the SUHI phenomenon and urban climate change. Understanding the SUHI phenomenon that brings enormous negative impacts to the environment and human life, Land Surface Temperature (LST) assessment is essential for creating a feasible and livable city. By utilizing the data of 1999 and 2018, this study aims to assess the LST value and its relationship to population density in Tanjungpinang city over two decades. As an island, Tanjungpinang has a vulnerability to SUHI and the climate change phenomenon. This study applied GIS and remote sensing models based on the mathematical formula of digital remote sensing images to calculate the LST value, and the relationship between LST and population density was examined using correlation analyses with Microsoft Excel. The results showed that Tanjungpinang city had increased 3.5oC in LST and 94.80% in density population over two decades. SUHI phenomenon has occurred during this period. It also indicated that there was a significant relationship between population density and LST. The LST spatial pattern spread from west to east of Tanjungpinang city was in line with the population density distribution pattern. The area with the highest percentage of population density addition and experienced the highest LST was Tanjungpinang Barat District. This study considers local governments to create effective population control and adaptive planning strategies for SUHI phenomenon mitigation.
