Understanding consumption and purchase of tap water and diverse tap-alternative drinking water sources in Detroit, Michigan

ABSTRACT Several gaps remain in understanding individuals' water consumption reliance outcomes in disadvantaged communities. We utilize a cross-sectional sample of household-level survey data from predominantly low-income, minoritized households in Detroit, MI, to examine the relationship between tap and tap-alternative drinking water consumption and purchase behavior. We collected survey data from one English-speaking adult per household in May–October 2021 (n = 259). Consistent with past studies, tap water consumption is negatively correlated with single-use bottled water consumption and consuming drinking water from multiple sources. We also find tap distrust is correlated with tap-alternative water consumption, yet there is a surprising positive relationship between tap and overall bottled water consumption levels. Very low-income households were more likely to rely on bottled water and multiple other water sources simultaneously. Female respondents reported lower levels of most types of water consumption. Black respondents reported lower tap water and bottled water consumption but had higher levels of other tap-alternative source consumption. Our results call into question whether higher tap water consumption is synonymous with tap trust or with reduced bottled water consumption. Public health interventions must further address high levels of bottled water consumption among low-income individuals, and low tap water consumption among Black individuals.

Variation characteristic analysis of regional agricultural water consumption under Budyko-type framework

ABSTRACT Agricultural water consumption security is crucial for maintaining food production stability. Aiming to investigate water consumption efficiency and objectives in agricultural and non-agricultural sectors, we adopted a Budyko-analogous framework to establish an optimal water allocation model based on the maximum water utilization benefits principle. The proposed Budyko framework was verified through its application in Anhui Province, China, and the difference in water utilization efficiencies among different regions was discussed. The research findings can be concluded as follows: (1) during 2011–2020, the provincial agricultural productive loss caused by per-unit water shortage was lower compared to non-agricultural sectors, and this trend was adaptive in the south but totally opposite in the north; (2) the guaranteed level of agricultural water consumption was higher compared to non-agricultural sectors in the north due to the predominance of agricultural production but totally contrary in the south. Overall, the above findings are consistent with the actual industrial structure of Anhui Province.

Correlation Mineral Water Consumption and Hemoglobin Levels in Adolescent Girls

Anemia is a global health issue that affects people of all ages, particularly adolescent girls. Adolescent girls require nutritional intake, both from food and water. According to the balanced nutrition guidelines, people (particularly adolescents and adults) require 2000 liters (or eight glasses) of water daily. Most adolescent girls barely consider their water consumption. A lack of water in the body affects the balance of minerals (salt and sugar), disrupting regular metabolic processes such as hemoglobin (Hb) level regulation. This study investigates the correlation between adolescent girls' water consumption and hemoglobin levels. This quantitative study uses a cross-sectional design to collect variable data at a certain time. The study used blood with anti-coagulants EDTA from 30 adolescent girls from Universitas Muhammadiyah Semarang. The primary data for this study are water consumption and hemoglobin levels. Results of the research show that adolescent girls' water consumption was adequate (66.7%) and low (33.3%). The average Hb level among adolescent girls was 12.4 g/dL. Adequate water consumption resulted in 3 respondents with low Hb levels and 7 with normal Hb levels. In contrast, low water consumption resulted in 2 respondents with low Hb levels and 18 with normal Hb levels. The Rank-Spearman correlation test showed sig 0.177 (p>0.05). The study concluded that there was no correlation between adolescent girl water consumption and hemoglobin levels. Food fluid intake can compensate for a lack of water consumption.

Propranolol attenuates the establishment of conditioned context aversions: differential effects compared to MK-801 in an animal model of anticipatory nausea and vomiting.

Cancer patients often experience anticipatory nausea and vomiting (ANV) due to Pavlovian conditioning. Both N-methyl-D-aspartate and beta-adrenergic receptors are known to mediate memory formation, but their role in the development of ANV remains unclear. This study used a conditioned context aversion (CCA) paradigm, an animal model for ANV, to assess whether administration of the beta-adrenergic receptor antagonist propranolol or the N-methyl-D-aspartate receptor antagonist MK-801 immediately after CCA training has an effect on the later expression of CCA in CD1 male mice. In experiment 1, three groups were injected with lithium chloride (LiCl) to induce aversion in a novel context, resulting in CCA. A control group was injected with sodium chloride (NaCl). Following conditioning, two of the LiCl-treated groups received different doses of MK-801 (0.05 or 0.2 mg/kg), while the remaining LiCl-treated and NaCl-treated groups received a second NaCl injection. In experiment 2, two groups were injected with LiCl, and one group was injected with NaCl. After conditioning, one of the LiCl-treated groups received a propranolol injection (10 mg/kg). The remaining LiCl-treated and NaCl-treated groups received NaCl injections. Water consumption was measured in all groups 72 h later within the conditioning context. Postconditioning administration of propranolol, but not MK-801, attenuated CCA, as revealed by similar levels of water consumption in animals that received LiCl and propranolol relative to NaCl-treated animals. These findings suggest that beta-adrenergic receptor activation is crucial for the development of CCA. Therefore, propranolol may represent a novel therapeutic approach for cancer patients at high risk of ANV.

Features of eating behavior of early school-age children in the context of the implementation of the school meals reform

The aim of this study is to study the peculiarities of the eating behaviour of children of primary school age, their food preferences, choice of products and attitudes towards school meals, food habits in the choice of products and attitudes towards the school canteen in the context of the implementation of the school meal reform. Materials and methods. A large-scale medical and sociological study was conducted, which included children (5,401) of primary school age (from 6 to 10 years old) and their parents (4,347 people) from various schools in Kyiv, Vinnytsia, and Donetsk regions. The questionnaires included questions about food preferences, frequency of consumption of different foods, attitudes towards school meals and factors that influence food choices. The collected data were processed and analyzed using descriptive statistics methods in Excel. Research results indicate a significant level of awareness of the importance of a healthy diet by most children, but an insufficient level of water consumption, an insufficient understanding of the importance of nutrition for maintaining health by children, high popularity of high-carbohydrate products and a low level of satisfaction of some parents with school meals. Conclusions. The conducted analytical research revealed several educational and organizational problems related to the introduction of healthy food in schools, especially within the framework of reforming school food programs. According to the Strategy for reforming the school nutrition system, compliance with the principles of healthy nutrition, ensuring high-quality, safe and healthy nutrition, and improving the taste properties of school nutrition compliance with the principles of healthy nutrition, is extremely important for the preservation of children's health and the prevention of chronic non-infectious diseases. The results of our research indicate the need for additional educational programs for children and parents, the gradual introduction of new food standards, as well as ensuring the availability of healthy food in school canteens, and the implementation of social projects that will contribute to the formation of healthy eating habits

Designing a heavy metal electrochemical sensor for Pb detection in water—A generalized approach for electrochemical sensing using low‐cost materials

AbstractThis work attempts to design an elemental method for detecting heavy metals in water. The presence of heavy metals in water is a critical issue that needs a check at every level of water consumption. To facilitate the checking, a simple method needs to be identified and developed. Electrochemical sensing is essentially a surface phenomenon and requires a higher surface area for greater accuracy and reliability. We have attempted to use a readily available Cu wire for detecting Pb to 50 μM concentration with 90% reliability. It is important to note that the sensing electrode (Cu wire) utilized for this work has been employed in a facile manner that enhances the ease of use for heavy metal electrochemical sensor. Moreover, post‐usage, the replacement of sensor material for subsequent usage is easy. The low cost and simplicity of the method make it ideal for resource‐constrained environments and portability, resulting in increasing the accessibility of water quality monitoring. The study examines the reliability of a low‐cost electrode for Pb concentration detection in water samples to the concentration of 50 μM using a simple low‐cost electrochemical sensor arrangement.

Estimation of Energy Balance throughout the Growing–Finishing Stage of Pigs in an Experimental Pig Barn

Monitoring the energy inputs and outputs in pig production systems is crucial for identifying potential imbalances and promoting energy efficiency. Therefore, the objective of this study was to measure the energy input, output, and losses during the growing–finishing phase of pigs from 1 September to 1 December 2023. A Livestock Environment Management System (LEMS) was used to measure the temperature, humidity, airflow, and water consumption levels inside the barn, and a load cell was used to measure the body weight of pigs. Furthermore, a bomb calorimetric test was conducted to measure the energy content of pigs’ manure. While calculating energy balance in the experimental barn, it was found that energy from feed and water contributed approximately 81% of the total input energy, while the remaining 19% of energy came from electrical energy. Regarding output energy, manure, and body weight accounted for about 69%, while around 31% was lost due to pig activities, maintaining barn temperature and airflow, and illuminating the barn. In conclusion, this study suggested methods to calculate energy balance in pig barns, offering valuable insights for pig farmers to enhance their understanding of input and output energy in pig production.

Nanocomposite Based on Bacterial Cellulose and Silver Nanoparticles Improve Wound Healing Without Exhibiting Toxic Effect

Wound healing is an important and complex process, containing a multifaceted process governed by sequential yet overlapping phases. Certain treatments can optimize local physiological conditions and improve wound healing. Silver nanoparticles (AgNP) are widely known for their antimicrobial activity. On the other hand, bacterial cellulose (BC) films have been used as a dressing that temporarily substitutes the skin, offering many advantages in optimizing wound healing, in addition to being highly biocompatible. Considering the promising activities of AgNP and BC films, the present study aimed to evaluate the wound healing activity in Wistar Hannover rats using a nanocomposite based on bacterial cellulose containing AgNP (AgBC). In a period of 21 days, its influence on the wound area, microbial growth, histopathological parameters, and collagen content were analyzed. In addition, toxicity indicators were assessed, such as weight gain, water consumption, and creatinine and alanine transaminase levels. After 14 days of injury, the animals treated with AgBC showed a significant increase in wound contraction. The treatment with AgBC significantly reduced the number of microbial colonies compared to other treatments in the first 48 h after the injury. At the end of the 21 experimental days, an average wound contraction rate greater than 97 % in relation to the initial area was observed, in addition to a significant increase in the amount of collagen fibers at the edge of the wounds, lower scores of necrosis, angiogenesis and inflammation, associated with no systemic toxicity. Therefore, it is concluded that the combination of preexisting products to form a new nanocomposite based on BC and AgNP amplified the biological activity of these products, increasing the effectiveness of wound healing and minimizing possible toxic effects of silver.

Enhancing Environmental Sustainability through Public Procurement: A Case Study of the National Environment Management Authority

The researcher examines the impact of public procurement on environmental concerns. The purpose of the study was to find out the impact of public procurement on environmental concerns. This study focused on the National Environment Management Authority as a case study. This study might help the National Environment Management Authority better advice the public on how to protect the environment through minimizing, reusing, and recycling the environment. The study was both descriptive and analytical, and the following instruments were used for collecting data: interviews, questionnaires, and documentary reviews. A sample section was used to select respondents who could participate in the research. The researcher recommends two types of public procurement. The government was to set minimum environmental standards for the procurement of a variety of goods. These standards were mandatory within the central government departments and agencies, as well as elsewhere in the public sector. The government was committed to sustainable procurement, which means only purchasing goods and services that are needed and buying items whose production, use, and disposal minimize negative impacts on the environment and society. Procurement is an important tool for helping a government meet its targets for operating sustainably, for example, by minimizing its use of energy and carbon dioxide emissions, water consumption, and waste levels, and increasing its recycling rates. Sustainable procurement also offers the opportunity and power to influence suppliers and the products they develop and design for the wider benefit of the economy and the environment. Partnership is a long-term collaborative form of relationship that is based on a high level of trust. The reason for this relationship with suppliers is risk reduction and product development to achieve better solutions.

Data Center Environmental Burden Reduction Through On-Site Renewable Power Generation

Abstract The energy demands from data centers contribute greatly to water scarcity footprint and carbon emissions. Understanding the use of on-site renewable power generation is an important step to gain insight into making data centers more sustainable. This novel study examines the impact of on-site solar or wind energy on data center water scarcity usage effectiveness (WSUE) and carbon usage effectiveness (CUE) at a U.S. county scale for a given data center size, water consumption level, and energy efficiency. The analysis uncovers combinations of specific metrics associated with grid-based carbon emissions and water scarcity footprint that enable predictions of the improvements anticipated when implementing on-site solar or wind energy. The implementation of on-site renewables has the most benefit in reducing carbon footprint in areas with high existing grid-based emissions such as the western side of the Appalachian Mountains (e.g., central and eastern Kentucky). The largest benefit in reducing water scarcity footprint is generally seen in counties with low water scarcity compared to adjacent areas (e.g., northern California).

Watershed water policy based on a glacier water service perspective in the typical glacier basins, Western China

Abstract Taking the Yangtze River Source Basin (YRSB) and Shule River Basin (SRB) as two typical cases, the sustainability of the water resources in these two basins was evaluated using the level of water stress (LWS) from sustainable development goal 6.4.2, and the regulating effect of the glacier runoff on the LWS was quantified. From 2000 to 2030, the level of socioeconomic development in the YRSB is low, and the total water consumption is only about 0.18 × 108 m3, whereas the SRB has a relatively high level of socioeconomic development and total water consumption is about 10 × 108 m3, i.e., 50 times higher than that in the YRSB. For the aforementioned reasons, the SRB's LWS is much higher than the YRSB's, resulting in a very low sustainability of water resources. As natural assets, glaciers flow downstream in the runoff mode, so compensation at the watershed scale should be considered. In the basin, the optimal allocation of water resources is needed. At the inter-basin scale, the compensation mechanism of glacier water resources needs to be improved.

Textile waste management and recycling opportunities and challenges for Africa

Global fibre supply increased to 113 million tonnes in 2021, contributing to elevated energy and water consumption levels, agricultural pollution, and post-consumer textile waste. Introducing second-hand clothing as an alternative to mitigate textile waste is advantageous for providing affordable clothing. However, the disposal of substandard and unsold garments obstructs riverways and drainage systems, leading to flooding. Moreover, incineration produces heightened greenhouse gas emissions, exacerbating poverty and impeding development, particularly in Africa. Nevertheless, textile wastes present opportunities for establishing large-scale regeneration and recycling facilities, offering the potential for employment generation and skill development in Africa. This mini-review aims to underscore Africa’s potential and challenges in textile waste recycling. The findings underscore the importance of recognizing African textile waste, both as an environmental hazard and as a valuable resource for the production of new clothing. Additionally, they emphasize how efforts to add value to recovered textiles are gaining traction, particularly in East, South, and North Africa. However, no formal textile recycling facilities were identified in West and Central Africa. This mini-review is constrained by data limitations, encouraging future researchers to broaden its scope by examining individual countries and recycling companies.

Synthesis of novel hydrazide Schiff bases with anti-diabetic and anti-hyperlipidemic effects: in-vitro, in-vivo and in-silico approaches

The increasing global incidence of non-insulin-dependent diabetes mellitus (NIDDM) necessitates innovative therapeutic solutions. This study focuses on the design, synthesis and biological evaluation of Schiff base derivatives from 2-bromo-2-(2-chlorophenyl) acetic acid, particularly hydrazone compounds 4a and 4b. Both in-vitro and in-vivo assays demonstrate these derivatives’ strong antidiabetic and anti-hyperlipidemic properties. In a 15-d experiment, we administered 4a and 4b at doses of 2.5 and 5 mg/kg body weight, which effectively improved symptoms of alloxan-induced diabetes in mice. These symptoms included weight loss, increased water consumption and high blood glucose levels. The compounds also normalized abnormal levels of total cholesterol (TC), triacylglycerol (TG) and low-density lipoprotein cholesterol (LDL-C), while raising the levels of high-density lipoprotein cholesterol (HDLC). Computational analysis showed that these compounds effectively inhibited the α-glucosidase enzyme by interacting with key catalytic residues, specifically Asp214 and Asp349. These computational results were confirmed through in-vitro tests, where 4a and 4b showed strong α-glucosidase inhibitory activity, with IC50 values of 0.70 ± 0.11 and 10.29 ± 0.30 µM, respectively. These compounds were more effective than the standard drug, acarbose, which had an IC50 value of 873.34 ± 1.67 µM. Mechanistic studies further indicated competitive inhibition, reinforcing the therapeutic potential of 4a and 4b for NIDDM treatment. Communicated by Ramaswamy H. Sarma

Hanehalkı Su Tüketimi ve Tarife Yapısı: Türkiye’de Üç Büyükşehir Üzerine Bir Analizi

Analysis of urban water management has been researched in several countries. However, the attention given to this subject in Türkiye remains limited. This study addresses this research gap by focusing on the analysis of water tariffs, a critical tool for urban water management policies of local governments in Türkiye. The research aim is to investigate issues related to the attributes widely studied globally when the Türkiye case is considered. The study utilises a dataset from the Household Budget Survey of the Turkish Statistical Institute (TÜİK) between 2015 and 2018. The research has two folds. First, household water tariffs, average water prices, water consumption levels, and household characteristics are comprehensively examined in three metropolitan cities of Türkiye, namely, İstanbul, Ankara, and İzmir. Secondly, water consumption data is compiled from diverse geographical regions worldwide and compared with the ones in Türkiye. The findings reveal that the accessibility to clean water and the financial burden of clean water on household budgets, particularly for low-income households in Türkiye, are notably disadvantaged compared to many developed countries.

Association between Physical Activity, Diet Quality and Leisure Activities of Young Poles.

The aim of this study was to determine the association between eating behaviours, sedentary behaviours and physical activity based on a self-reported survey conducted on a sample of the Polish population of adolescents aged 13-16. The field survey was conducted on a nationwide group of 6818 respondents. The object of the statistical analysis was to develop a model regarding the influence of selected socio-demographic characteristics on engaging in physical activity and selected dietary behaviours. Due to the dichotomous nature of the dependent variable, logistic regression models were used in the model. It was found that the higher the level of physical activity, the more well-balanced the diet, including higher levels of fruit consumption, water consumption and protein-containing products, as well as the relatively less frequent occurrence of sedentary behaviour as a form of leisure activity. However, there is a constant need to develop, in cooperation with scientific and research institutions and educational establishments, mechanisms for influencing a change in the behaviour of young people towards a more pro-healthy lifestyle so that the effects of these educational activities are not only reflected in an increase in the level of knowledge in this area but also contribute to real changes in dietary behaviour.

Experimental Evaluation of the Pharmacological Safety of a New Propagandic Acid Derivative with a Cardiotropic Action

We present the results of experimental studies into the pharmacological safety of a pharmaceutical substance 4-[(3-oxo-3-ethoxypropanoyl)amino]benzoic acid (Etmaben) under a single intragastric administration at various experimental doses (60–3000 mg/kg) to female laboratory outbred rats. A clinical examination of the experimental animals was carried out in order to identify signs of intoxication. To that end, the level of food and water consumption was assessed and biochemical blood tests were performed. In addition, the state of the central nervous and cardiovascular systems, physical endurance, and respiratory rate were assessed. The tested pharmaceutical substance in the studied doses after a single intragastric administration to female rats had no negative effect on the behavior, blood parameters, the state of the central nervous system and the cardiovascular system of experimental animals.

Thermal effectiveness and NTU of horizontal plate drain water heat recovery unit - experimental study

The operating characteristics of plate heat exchanger in horizontal drain water heat recovery unit for domestic shower system were investigated in an experimental study. Based on test data the thermal effectiveness (ε) and number of heat transfer units (NTU) were calculated. The tests were carried out in simulated real-world conditions in three shower water flow rates (water consumption levels) for 4, 8 and 12 l/min, and two primary and secondary flows configurations (balanced and unbalanced), as a reflection of the three shower intensity standards and water temperature range of 30–50 °C covering the usual user-specific shower conditions. The least favorable test results (ε = 18.6% and NTU = 0.24) were obtained for the drain water temperature of 26.6 °C and cold water / drain flow rate at 12/12 l/min. The most beneficial results (ε = 50.0% and NTU = 0.99) were obtained for the sewage temperature of 50.8 °C and 4/12 l/min. It has been shown that the higher the flow on the drain water side and lower on the cold water side, the better the effectiveness. For a system with equal and low flows on both sides, the drain temperature change has a negligible effect on the effectiveness (4% growth with a drain temperature increase of 25.4 °C for 4/4 l/min). The paper presents developed easy-to-use charts of the variability of the effectiveness and NTU with the drain water temperature relates to a different set of primary and secondary flows in horizontal, plate, compact drain water heat recovery exchanger. The results of effectiveness obtained in the research were compared to the values presented in the literature for other drain water heat recovery units, both in vertical and horizontal applications.

Convergence and influencing factors of urban domestic water consumption in the Yangtze River Delta under urbanization

ABSTRACT This study employs panel data from 41 cities from 2010 to 2019 in the Yangtze River Delta. The entropy weight method is used to calculate the urbanization level. Then, the convergence, panel spatial econometric, and threshold regression models are adopted to examine the convergence and to identify the factors affecting water consumption. The following conclusions may be drawn: Spatial differences in the level of domestic water consumption show a trend of gradual reduction over time; there exists mutual influence of neighboring cities; urbanization positively affects domestic water consumption significantly; the spatial spillover effect of urbanization on domestic water consumption is significantly negative; the promotion effect of urbanization on domestic water consumption is nonlinear, and the promotion effect increases with the increase of the proportion of domestic water and the proportion of public service water. Then, targeted countermeasures are brought forward.
