Moasheri, R., Jalili Ghazizadeh, M., and Ahmadi Kohanali, R.
- Abstract
Leakage in water distribution networks precipitates both water wastage and the ingress of pollutants. The localization of leaks, a formidable challenge within water demand management, has spurred an examination of hydraulic simulation-based methodologies as a more economically feasible and time-efficient alternative to conventional methods. This paper introduces a framework for precisely determining the location of leaks within a water distribution network, leveraging the Grasshopper Optimization Algorithm. The approach meticulously compares simulated data with pressure field information. Acknowledging the intrinsic uncertainties pertaining to hydraulic model parameters—such as elevations, nodal base demand, and pipe roughness coefficients in real-world water distribution networks—the developed method incorporates perturbation analysis for judicious parameter selection. Monte Carlo simulation is then employed to apply these parameters in the simulation process systematically. The efficacy of the method is demonstrated by applying it to benchmark water distribution networks (specifically, Poulakis and Balerma) under various leakage scenarios, achieving accuracy levels of up to 99%. Introducing uncertainty into the simulation process results in a maximum 20% reduction in method accuracy. Real-world implementation successfully and accurately localizes leakage, affirming the practical applicability of the proposed method for water utilities. [ABSTRACT FROM AUTHOR]

Timing plays a crucial role in plant survival as it determines the environmental conditions during which each phenophase develops. In Mediterranean regions, with high temperatures and low precipitation during summer, the timing of flowering may impact plant performance. Different species avoid harsh abiotic conditions by flowering weeks or months earlier than others. On a shorter time scale, conspecifics that flower just a few days earlier may also gain biotic advantages, such as reduced competition for nutrients or pollinators. We propose that earlier flowering, whether by days for conspecifics or by weeks to months for different species, allows plants to avoid biotic and abiotic stress, respectively, leading to increased reproductive success and growth. We hypothesize that: (i) earlier‐flowering species will have higher growth and reproductive success than other species co‐occurring in the community, and (ii) earlier‐flowering conspecifics will show higher growth and reproductive success than the average of their co‐occurring conspecifics. A field study was conducted in SE Spain using 98 co‐occurring individuals of four species. We monitored phenology, water loss, and growth over a growing season and estimated relative individual reproduction. Early‐flowering species did not show higher relative reproduction than late, co‐occurring flowering species, although they differed in water loss. However, early‐flowering conspecifics had higher growth and relative reproduction than later‐flowering conspecifics, but did not differ in water loss. Our results suggest that early flowering might reduce intraspecific competition among conspecifics, rather than enhance performance of those species that avoid harsh summer conditions (high temperatures and low precipitations).

Plant stems grow towards the incident light in response to unilateral blue light to optimize photosynthesis. However, our findings reveal that unilateral high-intensity blue light (HBL) triggers backlit lodging in etiolated cotton (Gossypium hirsutum) hypocotyls when they are pulled approximately 1.5 cm from the soil. Phenotypic analysis indicated that stomata on the lit side were open, while those on the shaded side were closed under unilateral HBL. To investigate the relationship between stomatal movement and backlit lodging, we applied abscisic acid (ABA), hydrogen peroxide (H2O2), and lanthanum chloride (LaCl3) to the lit side, and cytokinins (6-BA) and ascorbic acid (ASA) to the shaded side. Results showed that all these treatments inhibited the backlit lodging phenomenon, specifically, ABA, H2O2, and LaCl3 reduced stomatal opening on the lit side, while 6-BA and ASA enhanced stomatal opening on the shade side. These results demonstrate that HBL-induced asymmetrical stomatal opening on the lit and shade side of hypocotyl supports the backlit lodging phenomenon. Notably, maize (Zea mays), which lack stomata in the hypocotyl did not exhibit HBL-induced backlit lodging, whereas soybean (Glycine max), which has stomata in its etiolated hypocotyl, displayed a similar phenotype to that of cotton. Additionally, while both red light and low-intensity blue light (LBL) can induce stomatal opening, they do not trigger the backlit lodging phenomenon. These findings suggest that backlit lodging is a unique HBL-dependent response, but the mechanism need further investigation. Our study unravels that unilateral high intensity blue light (HBL) triggered backlit lodging of etiolated cotton (Gossypium hirsutum) hypocotyls. Unilateral HBL stimulates the change of turgor pressure of hypocotyl lit-side guard cells in cotton seedlings to absorb water from backlit side cells, which resulted in the backlit side cells shrinking and backlit lodging. Abscisic acid signaling can inhibit both HBL-induced stomatal opening and backlit lodging, indicated that the backlit lodging phenomenon attributed to HBL-induced stomatal opening.

Potatoes are typically stored at low temperatures (5.5–8.9 °C) and high relative humidity (95–97%) to reduce water loss, the primary factor contributing to tuber weight loss. Water loss occurs mainly through transpiration from the tuber skin (97.6%), with only 2.4% through the lenticels. However, ignoring respiration as a water-loss mechanism can lead to inaccurate weight-loss determinations. This study aimed to evaluate respiration's contribution to mass loss (water loss) in russet-type potatoes. Four russet-type cultivars (Russet Burbank, Ivory Russet, Dakota Russet, and Rainier Russet) were cured at 12.8 °C and 95% relative humidity for 14 days. After curing, the temperature was gradually reduced to 5.5 °C, 7.2 °C, or 8.9 °C with 95% RH and stored for up to 9 months. Dakota Russet had the highest and Ivory Russet the lowest weight loss during storage, irrespective of temperature. The transpiration rate per unit of initial mass varied by storage temperature, from 14 ± 50.014±0.005 g kg−1 h−1 at 5.5 °C, 16 ± 60.016±0.006 g kg−1 h−1 at 7.2 °C, and 17 ± 70.017±0.007 g kg−1 h−1 at 8.9 °C. The transpiration rate per unit area decreased until the 4th -5th month of storage. The water vapor pressure deficit was the main factor contributing to total weight loss, with respiration rates contributing less than 10%. Further studies are needed to understand why Dakota Russet experiences significantly greater weight loss than other russet cultivars, despite the observed data on respiration rates. • Dakota Russet Tubers had the highest mass loss regardless of storage temperature. • Dakota Russet had the highest effective diffusivity. • The transpiration rate per initial weight unit increased with storage temperatures. • Water vapor pressure deficit was the main factor contributing to total weight loss.

The Prespa–Ohrid lake system in the southwest Balkan region is the oldest permanent lake system in Europe and a global hotspot of biodiversity and endemism. Its smaller component, Lake Macro Prespa (or simply called Prespa), shared by North Macedonia, Albania and Greece has suffered a dramatic water-level fall (nearly 10 m since the 1950s). It was greater in the periods 1987–1993 and 1998–2004 and has further accelerated in the last 5 years. Analysis of satellite images (remote sensing) revealed that over the period 1984–2020 Prespa Lake lost 18.87 km
2 of its surface (6.9% of its size, dropping from 273.38 km2 to 254.51 km2 ), with a decline in the volume of water estimated as about 54%, even reaching 56.8% in 2022. The environmental status of the lake has also been compromised and the process of its eutrophication is enhanced. The aim of this study is to summarize the current understanding of the diminishing trend in the water level and the factors that have contributed to it. The lake is highly sensitive to external impacts, including climate change, mainly restricted precipitation and increased water abstraction for irrigation. Importantly, nearly half of its outflow is through karst aquifers that feed Ohrid Lake. Of note, the hydrology and especially hydrogeology of the catchment has not been studied in sufficient detail and accurate data for the present state are missing, largely due to a lack of coordinated investigations by the three neighboring countries. However, recent estimation of the water balance of Prespa Lake, elaborated with the consideration of only the natural sources of inflow (precipitation and river runoff) and outflow (evaporation and loss of water through the karst channels) suggested a negative balance of 53 × 106 m3 annually. Our study also offers an estimated projection for the water level in the future in different climate scenarios based on linear regression models that predict its complete loss before the end of the present century.

Water loss is a serious issue affecting the quality of postharvest horticultural products. Aquaporins (AQPs) regulate the transport of water across biological membranes, along the gradient of water potential, and may play a role in water loss. In this study, matured orange fruits (Citrus sinensis) stored at ambinent temperature (RH 85-95%) for 105 d showed that the weight loss persistently increased, and its rate peaked at 45–60 d and 90–105 d. Both water content and potential were higher in the pulp than in the peel. Water content rose before 60 d, and peel water potential fell with an increased gradient after 60 d. Comparing with peel, osmolytes such as soluble sugar, sucrose, glucose, fructose, and organic acids showed higher accumulation, and their levels were the lowest around 60 d. In contrast, soluble protein and inorganic minerals showed low levels of accumulation in the pulp. In total, 31 CsAQP genes were expressed in the fruit, and most of them were down-regulated in the peel but up-regulated in the pulp during storage. These genes were subsequently classified into four clusters based on their expression patterns. Genes in Cluster I — including CsNIP1;1/2;1/2;2/2;3/3;1/4;1/6;1 , CsTIP1;3/2;2/2;3/5;1/6;1 , CsXIP1;1/1;2 , CsSIP1;2 , and CsPIP1;2 — were persistently up-regulated in the pulp for the 105 d of storage, especially at day 60, when some genes showed 103-fold higher expression. Pearson's correlation and principal component analysis further revealed a significant positive correlation among weight loss rate, water content, and water potential gradient (R
2 = 0.85). Indexes positively correlated with osmolyte content and Cluster I gene expression in pulp samples suggest that increased CsAQP gene expression in pulp is linked to faster water loss in oranges, particularly at 60 days postharvest. [ABSTRACT FROM AUTHOR]- Published

Cold mixes containing reclaimed asphalt pavement (RAP) facilitate low energy, low-emission, economical, environmentally friendly, and sustainable means of pavement construction. The air voids in cold mixes lie within a broad range. Since cold mixes are evolutive materials, this study hypothesizes that varying air voids will have a major influence on short-term and long-term evolutive behaviour of cold mixes and should be checked. Moreover, there is still no clear agreement on equivalent relationships between accelerated (short-term) and ambient temperature (long-term) curing. There is lack of consensus concerning what residual moisture content should decide the optimal timing for placement of overlay or opening of traffic. Thus, in this study, cold mix containing 40% virgin aggregates and 60% RAP was designed and the samples were compacted at varying air voids of 6, 8, 10, and 12%. Thereafter, the samples were subjected to short-term curing (40 °C for 72 h) and long-term curing (at ambient temperature of 25 °C up to 180 days). The evolution of water loss (WL), drying process based on rate of evaporation, moisture content, bulk density, air voids, and indirect tensile strength (ITS) was determined for cured samples. These parameters were modelled using Michaelis–Menten (MM) model, standard quadratic polynomial model, and allometric power model. The results indicate that cumulative WL and air voids increase on both short-term and long-term curing. Rate of evaporation and bulk density decreases with the increase in initial air voids and long-term curing time. Short-term curing was found to be equivalent to 16–25 days of long-term curing based on ITSdry and equivalent from 18 to 26 days based on ITSwet. Residual moisture content requirement of 2% was found to be reasonable and cold mix reached this content after 14–21 days. Parametric evaluation based on MM model indicates that WL in first part of curing is faster than ITS development which suggests that curing associated with emulsion breaking and evaporation dominates the rate of gain of strength during initial period of curing whereas hydration of cement influences the delayed development of stiffness.

Abstract Plantain is consumed as a stable food in most sub-Saharan countries and to some extent in southern America and Asia. To avoid deterioration of the plantain after harvest and to provide food variety, a reasonable quantity of plantain is now being transformed into flour. Osmotic dehydration (OD) is a critical step in the flour production process because it enhances the nutritional and sensory quality of the flour. There are efforts to use alternative osmotic dehydration agents to sucrose and salts to avoid their high content in the final product which is believed to have serious negative effects on the health of consumers. Suitable alternatives are low-calorie sugars (LCS) because they have low glycemic indices but which unfortunately have not been tested for the OD of plantain. This work investigated osmotic dehydration process of unripe plantain using a commonly consumed commercial LCS (Sussli) as an osmotic agent. The effect of slice thickness, solution concentration, sample solution ratio and temperature on water loss (WL) and solute gain (SG) on the osmotic dehydration of plantain (Musa paradisiaca) were evaluated. All parameters had a significant influence on water loss and solid gain. The osmotic dehydration was modeled using the Azuara, Peleg and Page models. Plantain slice of thickness 5 mm, LCS solution concentration of 50% at ambient temperature (25 ± 2 °C), and a sample/solution ratio of 1:10 (w/v) were judged best for osmotic treatment of plantains in LCS. Under these conditions, the water loss and solid gain were 20% and 1.73% respectively. The best-fitted model was Peleg model with the highest R2 (0.999) and the least RMSE values.

Abstract This study investigates the risk of severe heat stress and associated potential water losses in professional soccer players, considering as well the oxygen content of the inhaled air in the context of the 2026 FIFA World Cup. For the 16 stadiums, hourly values of biometeorological indices (adjusted Universal Thermal Climate Index – UTCI, Water loss – SW and Oxygen volume - Ov) were calculated. UTCI adjustments included modifications to activity levels, movement speeds and clothing configurations to better reflect the level of thermal stress on soccer player during a match. Ten out of the sixteen sites of the 2026 FIFA World Cup are at very high risk of experiencing extreme heat stress conditions. The highest risk of uncompensable thermal stress due to very high average hourly UTCI values above 49.5 °C and excessive water loss (> 1.5 kg/h) occur in the afternoon in stadiums located in Arlington, Houston (USA) and in Monterrey (Mexico). The results of this study will enable optimization of match schedules at individual venues, taking into account the health risks associated with extreme heat stress, but also the physiological reactions to heat potentially affecting the performance of players on the pitch.

Abstract Water scarcity is a critical issue affecting numerous regions, including Addis Ababa, Ethiopia. The city’s growing population and rising water consumption place significant pressure on its existing water infrastructure. This study evaluates the impact of water loss due to leakages in the distribution system on the demand–supply gap in Addis Ababa, utilizing the WB EasyCalc software for analysis. Data analysis from 2023 indicate that monthly water loss contributes to an additional unmet demand of 5 million cubic meters (MCM), emphasizing the urgent need for effective water loss reduction strategies to enhance supply reliability. Currently, the city achieves only 42% water supply coverage, with an average loss of 300 L per connection per day and approximately 25,000 L lost per kilometer of pipeline daily. Furthermore, non-revenue water (NRW) accounts for 41.8% of total production, with real losses constituting 64%. The Infrastructure Leakage Index (ILI) score of 27 underscores the critical need for targeted leakage management interventions. The significance of this research lies in its quantification of water loss and its direct correlation with unmet demand in Addis Ababa. The findings provide essential insights for policymakers and stakeholders, highlighting the necessity for improved infrastructure management and strategic interventions to bolster water supply reliability. Implementing effective leakage reduction measures could substantially mitigate water scarcity challenges, thereby supporting sustainable urban development and enhancing public health outcomes in a city where access to clean water is vital for economic and social stability.

Article Highlights: Addis Ababa's water system suffers from a 41.8% water loss, significantly impacting supply reliability. Physical infrastructure issues like leaks and bursts contribute to 26.3% of the total water losses. Reducing water loss could close the demand–supply gap, ensuring a more sustainable and efficient water supply system. [ABSTRACT FROM AUTHOR]

LEAST squares - Abstract
There is a certain deviation between the calculated daily water loss and the actual water loss in the circulating water system of a certain refinery. Regarding this issue, the calculation of water loss in the circulating water system has been corrected. By comparing the water loss data of the experimental device with the calculated data and using the least squares method for fitting, the deviation rate between the actual loss amount and the calculated value can be controlled within 5% when the optimal interval change slope k of the fitted curve L is controlled between 1.06 -1.09 and the optimal interval change intercept b of the circulating water is controlled between 14 and 19. When k is set to 1.07 and b is set to 15, the maximum deviation rate is only 4.77%, which verifies the feasibility of the algorithm. [ABSTRACT FROM AUTHOR]

This study utilized data from the NASA Gravity Recovery and Climate Experiment (GRACE) to examine the variability of the terrestrial water storage anomaly (TWSA) in Iraq between 2002 and 2019. The analysis focused on six grid cells representing the Iraqi territory. The season trend decomposition (SLT) method was used to decompose the signal time series of TWSA to reveal the seasonality, trend, and random noise for the six GRACE blocks. Results proved that Block01 in northwestern side of Iraq, experienced a significant reduction in TWS between 2002 and 2009, followed by a negative linear trend until 2015, and then a positive trend. Block02 which is located in the northeastern part of Iraq showed a decreasing trend in TWS until 2008, after which it had a positive trend. Block03 in the western central side of Iraq reveals a decrease in TWS from 2002 to 2008, followed by a negative linear trend until 2016, and then a positive trend. Block04 in the eastern Mesopotamian plain had a minor increase in TWS until 2006, followed by a substantial decrease until 2016, before stabilizing and showing a positive trend. Block05 in the southwestern side of Iraq demonstrated a continuous decline in TWSA. In contrast, TWS increased in block6 on the southeastern side from 2002 to 2007, then decreased from 2007 to 2009. TWSA levels remained stable from 2009 to 2016, then increased from 2016 to the end of 2019. The seasonal fluctuations in TWS varied across the blocks, but generally, surpluses were observed in winter and spring, while deficits were observed in summer and autumn. The shortage in TWS is attributed to drought and excessive use of groundwater for irrigation. The recent positive trends in TWS in some blocks suggest that the drought may be coming to an end, but further analysis is necessary to reach a definitive conclusion. [ABSTRACT FROM AUTHOR]

Challenges in global food supply chains include preserving postharvest quality and extending the shelf life of fruits and vegetables. The utilization of edible coatings (ECs) combined with biocontrol agents (BCAs) represents a promising strategy to enhance the postharvest quality and shelf life of these commodities. This review analyzes the most recent developments in EC technologies and their combination with BCAs, highlighting their synergistic effects on postharvest pathogen control and quality maintenance. Various types of ECs, including polysaccharides, proteins, and lipids, are discussed alongside coating fundamentals and the mechanisms through which BCAs contribute to pathogen suppression. The review also highlights the efficacy of these combined approaches in maintaining the physicochemical properties, sensory attributes, and nutritional value of fruits. Key challenges such as regulatory requirements, consumer acceptance, and the scalability of these technologies are addressed. Future research directions are proposed to optimize formulations, improve application techniques, and enhance the overall efficacy of these biocomposite coatings and multifunctional coatings. By synthesizing current knowledge and identifying gaps, this review provides a comprehensive understanding of the potential and limitations of using ECs and BCAs for sustainable postharvest management.

Micelle silymarin (MS) is known for its various beneficial properties, including antiswelling, antioxidant, hepatoprotective and antidiabetic effects. The primary goal of this research was to investigate how MS impacts the performance, egg quality, water loss and blood profile of laying hens. 288 Hy‐Line brown laying hens, 28 weeks in age, were utilized for this experiment. The hens were randomly allocated into three dietary treatment groups, with each group comprising eight replicates of 12 hens, each housed in individual pens with access to feed and water. Over a 12‐week feeding trial, the hens were provided with a basal diet supplemented with different levels of MS: 0%, 0.03% and 0.06%. The results indicated that the inclusion of MS in the hens' diet did not have a significant impact on their performance (p > 0.05). However, Haugh units, egg weight and eggshell strength showed a linear improvement (p < 0.05) throughout the entire trial period with MS supplementation. Furthermore, there was a linear decrease in egg yolk colour and eggshell thickness showed linear improvements (p < 0.05), particularly during Week 8, with MS supplementation. Moreover, layers fed diet supplemented with MS showed a linear increased (p < 0.05) in albumen height and eggshell thickness in Week 12. In addition, egg water loss during Week 12, the third day of incubation, linearly decreased as an effect of the increasing level of the MS in the laying hen's diet (p < 0.05). Regarding blood profile parameters, the study revealed a tendency for alkaline phosphatase to decrease, whereas aspartate aminotransferase and cholesterol levels were linearly decreased (p < 0.05). In summary, increasing the level of MS supplementation in the diet of laying hens appeared to be beneficial in improving egg quality, slight improvement for egg water loss and certain aspects of blood profile parameters, without adversely affecting the hens' growth performance.

Background: Coconut (Cocos nucifera L.) is considered a highly valuable and beneficial perennial crop in our country. The basal portion of the coconut embryo enlarges during germination and forms a spongy structure, haustorium, which is an excellent source of essential nutrients. Since consumer preference is shifting towards healthy food and processed coconut products have immense scope in this sector, the study was conducted to standardize the process variables for osmo-dehydration of coconut haustorium and to evaluate the nutritional qualities of the osmo-dehydrated product. Methods: The present study involved the development of osmo-dehydrated coconut haustorium by standardizing the process variables, viz., osmotic solution concentration and immersion time. Mass transfer, physical, biochemical and sensory parameters were analysed to evaluate the nutritional qualities and consumer acceptance. Result: The results on biochemical properties revealed that an increase in concentration and time of immersion increased TSS, total sugar, reducing sugar, ash and mineral content. The process variables were standardized for the development of osmo-dehydrated coconut haustorium with optimum mass transfer characters, better nutritional qualities and consumer acceptance, which has application in the food industry.

Superfine tailings-blast furnace slag backfill (SBB) has been designed for recycling solid waste in mines and decreasing the cost of the overall process. During the mining process, the decrease of adjacent ore rock causes backfills water loss and its exposure to air. The mechanical behavior of SBB was investigated by uniaxial compressive strength (UCS), acoustic emission (AE) characteristics, and numerical simulations. Wavelet transform and fast Fourier transform were used to obtain the frequency components of AE events during the whole loading. The results indicated that the main frequency components of AE signals in SBB were close to 100 kHz, while medium and high-frequency components could be also distinguished for specific specimens with certain water loss. Particle flow code (PFC), a typical discrete element method (DEM), could reproduce the stress–strain curves of SBB specimens with varied water loss and simulate AE events of SBB during the loading. For the whole loading process, both indoor experiments and numerical simulation showed that AE events and simulated AE clusters began in the early stage of loading, which indicated that the crack initiated from a low stress level.

Introduction: Skin barrier dysfunction is an important component of atopic dermatitis (AD) pathophysiology. Topical corticosteroids (TCSs) are the mainstay therapy, but steroid phobia is emerging due to potential side effects. We aimed to determine the short-term effect of clobetasone butyrate on patients with AD. Methods: This investigator-blinded, randomised, moisturiser-controlled study evaluated patients with stable mild-to-moderate AD. Clobetasone butyrate ointment plus aqueous cream (Aq) or Aq alone was applied on randomised sites twice daily for 6 weeks. The itch score, modified Eczema Area and Severity Index (M-EASI) and epidermal biophysical parameters were assessed at baseline and 1 h, 3 h, 2 weeks and 6 weeks after application. Results: Sixteen patients, among whom 14 (87.5%) were women and two (12.5%) were men, participated in the study. There were no significant differences in pH, transepidermal water loss (TEWL) and hydration between TCS + Aq and Aq from 1 h to 6 weeks. A non-significant trend of pH increment was observed with TCS + Aq from baseline to 6 weeks. TEWL and hydration improved at 6 weeks for both treatment arms. The difference in TEWL from baseline was significant with Aq (P=0.01). The M-EASI at 6 weeks was comparable between the two arms. TCS + Aq improved itch and erythema better than Aq (P=0.02). No cutaneous adverse effects were observed at both sites. Conclusion: Short-term application of clobetasone butyrate with Aq is safe with no significant changes in epidermal biophysical parameters while controlling the symptoms and signs of eczema faster than Aq alone.

This study presents a new visual-based method that uses a thermal tracer and infrared thermography to detect sink points in shallow flooded areas. Laboratory experiments were conducted in a 2 × 2 m
2 soil flume where different scenarios with varying sink characteristics (e.g., permeability) were examined. To detect the sink point, hot water was continuously applied to create a temperature gradient across the flooded area, and multiple tracer discharges were tested. A portable infrared video camera was used to obtain high-resolution thermal imaging. The sink detection method was based on tracking the leading edge of the tracer's plume over time. This method successfully identified water sink points in most experimental scenarios and provided valuable insights into surface flow processes. Specific combinations of tracer discharge and sink characteristics (e.g., location and saturated hydraulic conductivity) could influence the method's effectiveness in detecting the sink location.

High temperatures that prevail at sun-exposed sites such as heaths, depressions, or on slopes, increase the risk of desiccation for rove beetles (Staphylinidae). Therefore, atmospheric and sub-atmospheric humidity determine the microclimates and thus habitat preference and activity of xerothermophilous species. In the nature reserve Marienfließ, a heathland in the south of Mecklenburg-Western Pomerania, Northeast German Lowlands, air temperature and humidity were recorded year-round along a transect at 10 sites, i.e. where the vegetation was more dense and more humid than where the vegetation was sparse and it was drier, using data loggers placed in the litter layer that recorded the conditions every 30 min in 2021. Monthly visits were made to determine the biomass of vegetation, soil and litter properties, edaphic rove beetle fauna and total abundance and and that of individual species at 1 m2 sites. Statistical analysis of 365 diurnal cycles per site, with pronounced amplitude in air temperature and humidity, clearly delineated the cooler and more humid sites from warmer and drier ones. Between 10 and 22 of the 30 xerothermophilous species (73.3%), such as, e.g. Quedius persimilis Mulsant & Rey, 1876, Xantholinus gallicus Coiffait, 1956, Cousya longitarsis (Thomson, 1867) and Euaesthetus superlatus Peyerimhoff, 1937, were recorded only at the cooler and moist sites on the heath. Comparison of the abundances and distribution of species revealed that the xerothermophilous heath-dwelling and desiccation-prone species prefer rather constant environmental conditions, i.e. niches in cool and moist habitats on warm and dry heathland.

The search for an effective and reliable model for predicting accidents on water supply networks by determining their exact locations has always been important for effectively managing water distribution systems. This study, based on the adaptive neuro-fuzzy logical inference system (ANFIS) model, was developed to predict accidents in the city of Kyiv (Ukraine) water supply network. The ANFIS model was combined with genetic algorithms and swarm optimization (ACO) methods and integrated into a GIS to visualize results and determine locations. Forecasts were evaluated according to the following criteria: mean absolute error (MAE), root mean square error (RMSE), and coefficient of determination (R2). Depending on the amount and type of input data, ANFIS optimization with genetic algorithms and swarm optimization (ACO) can, on average, increase the accuracy of ANFIS predictions by 10.1% to 11%. The obtained results indicate that the developed hybrid model may be successfully applied to predict accidents on water supply networks.

The present work investigated the pressure changes caused by water hammer through the georeferenced model to investigate the stress impact on water transmission lines. The results of the hydraulic analysis of the research showed that the sudden stop of the pumps in the transmission line 1,600 m in length caused negative pressures of −5 to −10 (bar). In pressure values close to −10 (bar), the water vaporization, cavitation, and separation of the column happened. The maximum pressure in the transmission line was calculated to be 43 (mH2O) and the minimum pressure in the transmission line was 10 (mH2O). The relative vacuum mentioned in the transmission line as a destructive factor caused two columns of steam and water to collide. The collision of two columns caused a great pressure that had the potential to destroy the transmission line. The research results showed that the maximum amount of elastic strain was equal to 16772E-7 mm/m. The equivalent stress beneath the pipe Q4 varied from 0.000 to 7E-2 m and the maximum stress value was 3.3535E7 (Pascal). The maximum amount of deformation or change in the shape and size of the pipe due to the applied stress (0.000–7E-2 m) was equivalent to 1.9287E5 m. HIGHLIGHTS Conceptual model for the water transmission line.; Investigation of the most critical point geospatial location.; Determination of critical points due to the water hammer in the transmission line.; Meshing and analysis of the most critical point on the pipeline and supports in the transmission line.; Concrete support for the most critical point to deal with the maximum stress in the transmission line.;

Infrastructure service affordability has become a burgeoning concern over the past years due to the recent economic crisis and the growing role of tariffs in funding the services. Pressure on utilities to promote social assistance programs in addition to an efficient service has risen toward providing water as affordable as possible. This study shows the positive impact of efficient services on families' water affordability by analyzing the new Brazilian water loss goals and the potential effect of water loss reduction on total expenses reported in the Brazilian utilities' National Water and Sanitation Information System. The total service cost for water and sanitation (before and after the aforementioned goals) was then translated to average tariff per cubic meter and affordability ratios. The potential water volume saved in physical losses can reach up to 16.6% of the water consumed in the country, and although the impact on water affordability was timid, the positive results indicate utilities have an important role in assuring water and sanitation for all, and regulators must be involved toward taking a deep look at local conditions. HIGHLIGHTS Efficient utilities have an important role on water affordability.; The new Brazilian water loss goals have potential positive outcomes for families’ budget.; Several Brazilian utilities may not achieve financial savings due to nonrevenue water programs costs.;

This paper aims to assess non-revenue water (NRW) in the urban water distribution system in Cameroon. The methodological approach used in this study was based on online searches using the databases such as Google Scholar, Web of Science, PubMed, and the International Water Association. These online searches have been completed through field observations and interviews with institutional and non-institutional stakeholders in the urban water sector. Results indicate that the total volume of NRW in the urban area of Cameroon was 100.26 million m3/year, which represents 52.5% of the total system input volume. About 2 million people could be supplied by cutting Cameroon's NRW to half the present level. Findings also suggest that the water utility (Camwater) practices passive leakage control, meaning that Camwater repairs only those leaks that are visible. Reducing NRW can be achieved through leakage detection and pipe replacement, pressure management, water metering, and a program to identify, remove, and replace illegal connections. HIGHLIGHTS This study shows that the annual volume of non-revenue water (NRW) is estimated at 274,679.2 m3/day, or 100.26 million m3/year, which represents about 52.5% of the annual system input volume.; About 4 million people (14% of the population) could be supplied with the present level of NRW.;

The aim of this study was to apply osmotic dehydration (OD) to produce minimally processed chayote (Sechium edule (Jacq.) Swartz) slices. Thus, the effect of osmotic solution concentration, temperature, processing time, and vacuum pulse application on mass transfer during osmotic dehydration of the fruit was evaluated. The kinetics of water loss (WL), solids gain (SG), and water activity (aw) were obtained using sucrose solutions with concentrations of 40, 50 and 60 °Bx at 25, 35 and 45 °C. Osmotic solution concentration, temperature, and processing time had a greater influence than vacuum pulse application on WL and SG. The temperature showed an Arrhenius-type dependence on effective diffusivity. The osmodehydrated chayote had lower aw (up to 0.846), higher total soluble solids (TSS) content (up to 31.9 °Bx) and purer and more intense color (up to 18.75 in chroma) compared to fresh chayote. These findings suggest that OD allows for the production of minimally processed chayote that could be included in quick-cook products, such as salads or soup mixes. [ABSTRACT FROM AUTHOR]

SUMMARY: The plant cuticle is composed of cuticular wax and cutin polymers and plays an essential role in plant tolerance to diverse abiotic and biotic stresses. Several stresses, including water deficit and salinity, regulate the synthesis of cuticular wax and cutin monomers. However, the effect of wounding on wax and cutin monomer production and the associated molecular mechanisms remain unclear. In this study, we determined that the accumulation of wax and cutin monomers in Arabidopsis leaves is positively regulated by wounding primarily through the jasmonic acid (JA) signaling pathway. Moreover, we observed that a wound‐ and JA‐responsive gene (CYP96A4) encoding an ER‐localized cytochrome P450 enzyme was highly expressed in leaves. Further analyses indicated that wound‐induced wax and cutin monomer production was severely inhibited in the cyp96a4 mutant. Furthermore, CYP96A4 interacted with CER1 and CER3, the core enzymes in the alkane‐forming pathway associated with wax biosynthesis, and modulated CER3 activity to influence aldehyde production in wax synthesis. In addition, transcripts of MYC2 and JAZ1, key genes in JA signaling pathway, were significantly reduced in cyp96a4 mutant. Collectively, these findings demonstrate that CYP96A4 functions as a cofactor of the alkane synthesis complex or participates in JA signaling pathway that contributes to cuticular wax biosynthesis and cutin monomer formation in response to wounding. Significance Statement: Plant cuticle is a lipidic barrier composed of cuticular wax and cutin polymers. Cuticle plays a critical role in protecting plants from various biotic and abiotic stresses. Wounds due to mechanical damage or insect feeding are common and are potentially harmful to plants. However, the effect of wounding on plant cuticular wax and cutin monomer biosynthesis remains unclear. In our study, the findings present the validation that the Arabidopsis cuticle development was positively regulated by wounding mainly through the jasmonic acid (JA) signaling pathway. We also characterized the wound‐ and JA‐responsive gene CYP96A4, which is required for wound‐ and JA‐induced synthesis of cuticular wax and cutin monomer. [ABSTRACT FROM AUTHOR]

- Abstract
Summary: Water retention technology plays a critical role in enhancing the flavour and yield of meat products, as well as maximising the economic advantages of meat processing in contemporary practices. This technique enhances the economic viability of the firm by augmenting the texture profile of meat products and optimising the yield. Water retention approaches essentially encompass the manipulation of pH levels, the inhibition of protein oxidation denaturation, and the alteration of the micro‐spatial structure of muscles. This study reviewed the different factors that contribute to water loss in meat and meat products, encompassing aspects such as animal species and cuts, pH levels, processing methodologies, storage and packing conditions, and salt concentration. This study reviewed the application of water retention techniques in the context of meat processing and its resultant products. The primary objective of this study is to offer theoretical justification for the reduction of juice loss, preservation of essential water content, enhancement of texture, and improvement of meat quality throughout the stages of processing and storage.

- Abstract
This study was conducted to explore the use of non-expansive soil as protective cover for expansive soil slopes. Laboratory model experiments were carried out on expansive soil systems with varying thickness of non-expansive soil cover. The models were subjected to three wet-dry cycles. Variation in soil moisture content was monitored using moisture probes. Surface and internal cracking of soil was observed using cameras. Variation of infiltration rate of the cover with wet-dry cycles was measured in-situ. Results of the study show correlation between cover thickness and evaporation rate and crack formation in the expansive soil. Crack size, quantity, depth, and interconnectivity in the expansive soil increased with decreasing cover thickness. Even the thinnest cover significantly reduced the the number and depth of cracks. The infiltration rate of the cover remained unchanged after three cycles wet-dry cycles. The final water content, after the third drying, in the expansive soil increased with increasing cover thickness. [ABSTRACT FROM AUTHOR]

Water loss is a serious issue affecting the quality of postharvest horticultural products. Aquaporins (AQPs) regulate the transport of water across biological membranes, along the gradient of water potential, and may play a role in water loss. In this study, matured orange fruits (Citrus sinensis) stored at ambinent temperature (RH 85-95%) for 105 d showed that the weight loss persistently increased, and its rate peaked at 45–60 d and 90–105 d. Both water content and potential were higher in the pulp than in the peel. Water content rose before 60 d, and peel water potential fell with an increased gradient after 60 d. Comparing with peel, osmolytes such as soluble sugar, sucrose, glucose, fructose, and organic acids showed higher accumulation, and their levels were the lowest around 60 d. In contrast, soluble protein and inorganic minerals showed low levels of accumulation in the pulp. In total, 31 CsAQP genes were expressed in the fruit, and most of them were down-regulated in the peel but up-regulated in the pulp during storage. These genes were subsequently classified into four clusters based on their expression patterns. Genes in Cluster I — including CsNIP1;1/2;1/2;2/2;3/3;1/4;1/6;1, CsTIP1;3/2;2/2;3/5;1/6;1, CsXIP1;1/1;2, CsSIP1;2, and CsPIP1;2 — were persistently up-regulated in the pulp for the 105 d of storage, especially at day 60, when some genes showed 103-fold higher expression. Pearson’s correlation and principal component analysis further revealed a significant positive correlation among weight loss rate, water content, and water potential gradient (R2 = 0.85). Indexes positively correlated with osmolyte content and Cluster I gene expression in pulp samples suggest that increased CsAQP gene expression in pulp is linked to faster water loss in oranges, particularly at 60 days postharvest.

Water loss is a critical concern in postharvest fruit technology, significantly impacting fruit quality, shelf life, and market value. This phenomenon involves the loss of moisture from fruit tissues, leading to physiological changes, reduced quality, and lower market value, which can contribute to food waste. Consumers perceive fruit with visible signs of water loss as lower quality. Therefore, minimizing water loss is essential through proper postharvest handling and storage practices, including temperature and humidity control, cooling, humidification, and the application of edible coatings and new modified coating techniques. Despite the importance of managing water loss, comprehensive information on its mechanisms and contributing factors in postharvest fruit technology is scarce. This paper aims to provide insights into the mechanisms, impact, influencing factors, and control strategies related to water loss in the context of postharvest fruit technology.

This work aimed to determine the optimum conditions for dehydration impregnation by immersion (D2I) and by intermittent immersion (D3I) of mango (Mangifera indica) slices measuring 4 × 1 × 1 cm3. To this end, the Doehlert response surface plan was used, with the following factors for D2I: the volume of D2I solution/fruit mass ratio (6/1–13/1 mL/g), the process time (120–360 min) and the Brix degree of the solution (45–65 °Brix) and with the following factors for D3I: immersion time (20–60 min), process time (60–300 min) and de-immersion time (7–25 min). The temperature was fixed according to literature at 35 °C. The optimum responses obtained for the D2I process were (47.63 ± 1.79) g/100 g (w-b) for water loss, and (6.67 ± 1.04) g/100 g (w-b) for solute gain, for optimum operating conditions of 6/1 mL/g; 245 min and 61.6°Brix respectively for the immersion ratio, process time and solute concentration of the hypertonic solution. The optimum responses obtained for D3I process were (47.98 ± 2.12) g/100 g (w-b) for water loss, and (4.31 ± 0.052) g/100 g (w-b) for solute gain (SG), for operating conditions of 21; 270; and 9 min, respectively for immersion time, process time and de-immersion time. The Student's t-test on the predicted and experimental optima of WL and SG revealed valuable insights for comparing these two processes. The present study will undoubtedly introduce a new dynamic to the osmotic dehydration systems for fruits and vegetables.

The Prespa–Ohrid lake system in the southwest Balkan region is the oldest permanent lake system in Europe and a global hotspot of biodiversity and endemism. Its smaller component, Lake Macro Prespa (or simply called Prespa), shared by North Macedonia, Albania and Greece has suffered a dramatic water-level fall (nearly 10 m since the 1950s). It was greater in the periods 1987–1993 and 1998–2004 and has further accelerated in the last 5 years. Analysis of satellite images (remote sensing) revealed that over the period 1984–2020 Prespa Lake lost 18.87 km2 of its surface (6.9% of its size, dropping from 273.38 km2 to 254.51 km2), with a decline in the volume of water estimated as about 54%, even reaching 56.8% in 2022. The environmental status of the lake has also been compromised and the process of its eutrophication is enhanced. The aim of this study is to summarize the current understanding of the diminishing trend in the water level and the factors that have contributed to it. The lake is highly sensitive to external impacts, including climate change, mainly restricted precipitation and increased water abstraction for irrigation. Importantly, nearly half of its outflow is through karst aquifers that feed Ohrid Lake. Of note, the hydrology and especially hydrogeology of the catchment has not been studied in sufficient detail and accurate data for the present state are missing, largely due to a lack of coordinated investigations by the three neighboring countries. However, recent estimation of the water balance of Prespa Lake, elaborated with the consideration of only the natural sources of inflow (precipitation and river runoff) and outflow (evaporation and loss of water through the karst channels) suggested a negative balance of 53 × 106 m3 annually. Our study also offers an estimated projection for the water level in the future in different climate scenarios based on linear regression models that predict its complete loss before the end of the present century.

This paper aims to assess non-revenue water (NRW) in the urban water distribution system in Cameroon. The methodological approach used in this study was based on online searches using the databases such as Google Scholar, Web of Science, PubMed, and the International Water Association. These online searches have been completed through field observations and interviews with institutional and non-institutional stakeholders in the urban water sector. Results indicate that the total volume of NRW in the urban area of Cameroon was 100.26 million m³/year, which represents 52.5% of the total system input volume. About 2 million people could be supplied by cutting Cameroon's NRW to half the present level. Findings also suggest that the water utility (Camwater) practices passive leakage control, meaning that Camwater repairs only those leaks that are visible. Reducing NRW can be achieved through leakage detection and pipe replacement, pressure management, water metering, and a program to identify, remove, and replace illegal connections.

Infrastructure service affordability has become a burgeoning concern over the past years due to the recent economic crisis and the growing role of tariffs in funding the services. Pressure on utilities to promote social assistance programs in addition to an efficient service has risen toward providing water as affordable as possible. This study shows the positive impact of efficient services on families' water affordability by analyzing the new Brazilian water loss goals and the potential effect of water loss reduction on total expenses reported in the Brazilian utilities' National Water and Sanitation Information System. The total service cost for water and sanitation (before and after the aforementioned goals) was then translated to average tariff per cubic meter and affordability ratios. The potential water volume saved in physical losses can reach up to 16.6% of the water consumed in the country, and although the impact on water affordability was timid, the positive results indicate utilities have an important role in assuring water and sanitation for all, and regulators must be involved toward taking a deep look at local conditions.

Taking care of water resources and minimizing water losses in water supply networks requires a broad approach to identifying and neutralizing operational problems. The correct selection of water meters to minimize apparent losses requires knowledge of the characteristic flows that may occur in the facility to which water is supplied. The research aimed to develop tools in the form of mathematical models and water consumption curves along with hourly water consumption coefficients to facilitate the process of selecting water meters for engineers and creating computer models of water supply systems. The research involved monitoring the flow of 76 single-family and multi-family buildings in four towns in Poland, followed by data analysis and development of tools supporting the selection of water meters and the construction of computer models of water distribution networks. High correlation coefficients of the studied variables indicate the results' usefulness. Four models were developed to determine the maximum flow values in multi-family buildings (three models) and single-family buildings (one model) in the range of water meter diameters DN15-DN40. Characteristics of the average hourly peak coefficient (HPC) values were also developed, along with the range of changes in HPC values for single-family and multi-family buildings.
