Sanitary management and the presence of Salmonella spp. in a small-scale aviary and poultry carcasses

Salmonella spp. is one of the primary foodborne pathogens and is a problem for public health and poultry farming. This study aimed to evaluate the sanitary management of a small poultry farm of a family farming company under female management in Jataí-GO and how such management affects the presence of Salmonella spp. Samples were collected for microbiological analysis from the environment of two batches of chicks at the entrance (D0), on the 28th (D28) and the 60th (D60) day of the chicks; from the carcass, from the evisceration table and the chicken plucker. The presence of Salmonella spp. was not detected in any of the samples, which were taken from the bottoms of the transport boxes, from eggshell residues, from the growth and fattening rations, from shoe covers, from chicken litter, from the reception sheds, from the feeders and water fountains, from the walls and screens, from the external area of ​​the shed, from the compost pile and the carcasses. The pH, water chlorine, ambient temperature, and carcass temperature were assessed using a good production practices monitoring form and were considered adequate. The descriptive analysis of the data considered the current legislation. Therefore, strict monitoring of the standards underlying the Good Manufacturing Practices (GMP) and Standard Hygiene Operating Procedures (SHOP) programs controlled the spread of Salmonella spp. in the poultry meat rearing and processing process and also ensured the quality of the final product for consumption.

Dust formation in common envelope binary interactions – II: 3D simulations with self-consistent dust formation

ABSTRACT We performed numerical simulations of the common envelope (CE) interaction between thermally pulsing asymptotic giant branch (AGB) stars of 1.7 and 3.7 M$_{\odot }$, respectively, and a 0.6 M$_{\odot }$ compact companion. We use tabulated equations of state to take into account recombination energy. For the first time, formation and growth of dust is calculated explicitly, using a carbon dust nucleation network with a C/O abundance ratio of 2.5 (by number). The first dust grains appear within $\sim$1–3 yr after the onset of the CE, forming an optically thick shell at $\sim$10–20 au, growing in thickness and radius to values of $\sim$400–500 au over $\sim$40 yr, with temperatures around 400 K. Most dust is formed in unbound material, having little effect on mass ejection or orbital evolution. By the end of the simulations, the total dust yield is $\sim 8.4\times 10^{-3}$ and $\sim 2.2\times 10^{-2}$ M$_{\odot }$ for the CE with a 1.7 and a 3.7 M$_{\odot }$ AGB star, respectively, corresponding to a nucleation efficiency close to 100 per cent, if no dust destruction mechanism is considered. Despite comparable dust yields to single AGB stars, in CE ejections the dust forms a thousand times faster, over tens of years as opposed to tens of thousands of years. This rapid dust formation may account for the shift in the infrared of the spectral energy distribution of some optical transients known as luminous red novae. Simulated dusty CEs support the idea that extreme carbon stars and ‘water fountains’ may be objects observed after a CE event.

Enhancing Visualization of Roman Aqueducts and Water Canalization in Volubilis, Morocco: A Study Using UAV Photogrammetry and Field Observations

This study investigates the application of Small Unmanned Aerial Vehicle (UAVs) photogrammetry alongside field observations to enhance the visualization of aqueduct and water canalization systems in Volubilis, Morocco, a UNESCO World Heritage site. Focused on the Roman period, the research explores the aqueducts’ role in supplying water to diverse structures, including private houses, cisterns, public fountains, baths, official buildings, and public latrines. The city’s growth from the Mauretanian period to its establishment as a Roman municipality in 42 A.D. witnessed the development of significant structures and an intricate water management system. The aqueducts sourced water from the springs of Fertassa and Laksar, utilizing the topography and gravity to direct water from upland to Volubilis. In contrast to previous studies relying on surface observations and/or geophysical methods, the research herein study integrates both photogrammetry and field observation techniques. Orthomosaics maps, digital 3D models, and Digital Elevation Models (DEMs) obtained from Small Unmanned Aerial Vehicles (UAVs) surveys of Volubilis were used to illustrate the aqueducts’ orientation and direction of canalization within the city. The complex network of water systems within houses is exemplified by the House of Venus and the House of Orpheus. The study identifies three main categories: surface and subsurface canals, intra-wall conduits made of ceramic or lead, and/or a combination of both. Despite gaps resulting from the loss or collapse of entire structures, the study successfully connects water conduits from aqueducts to various locations in Volubilis. The DEM underscores the crucial role of gravity in water distribution, prompting inquiries into the mechanisms involved and suggesting potential employment of surface, siphoning, over-wall canalization, and/or a combination thereof. Photogrammetric analysis, coupled with meticulous field observations, contributes to the reconstruction of a comprehensive conceptual model of the hydraulic system of Volubilis. The latter showcases elaborate water basins, latrines, baths, and fountains, with water directed through a vertical ceramic pipe fed by underground channels originating from the main aqueduct crossing the center of Volubilis. This research provides valuable insights into Roman water supply and infrastructure management, highlighting the seamless integration of photogrammetry, field observations, and historical evidence. The findings significantly contribute to our understanding of ancient aqueduct systems and their role in sustaining urban life in the Roman city of Volubilis.

Excited-state OH Masers in the Water Fountain Source IRAS 18460-0151

Water fountain objects are generally defined as evolved stars with low to intermediate initial mass accompanied by high-velocity molecular jets detectable in the 22.235 GHz H2O maser line. They are the key objects of understanding the morphological transitions of circumstellar envelopes during the post asymptotic giant branch phase. Masers are useful tools to trace the kinematic environments of the circumstellar envelopes. In this Letter we report the discovery of exceptionally uncommon excited-state hydroxyl (ex-OH) masers at 4660 and 6031 MHz toward the water fountain source IRAS 18460−0151. These are the brightest ex-OH masers discovered in late-type objects to date. To the best of our knowledge, prior to the current work, no evolved stellar object has been observed in the 4660 MHz ex-OH maser line. The ground-state hydroxyl (g-OH) masers at 1612 and 1665 MHz are also observed. The velocity components of the 4660 MHz ex-OH maser line and the much weaker 1665 MHz g-OH maser line all can be seen in the 1612 MHz g-OH maser line profile. The blueshifted components of the three masers are more intense than the redshifted ones in contrast to the ex-OH maser line at 6031 MHz. The relevance of the behaviors of the ex-OH masers to the circumstellar environments is unclear.

PYAAVS AND PAANPOIS - A STUDY OF THE CHANGING FACE OF PUBLIC WATER DISPENSING UNITS OF PUNE

Water has always been an essential part of human civilization, shaping urban landscapes and influencing social life. The drinking water fountains built during colonial period are locally called as pyaavs while water dispensing units are generally called as paanpois. Two old drinking water fountains and some new water dispensing units are located within the Pune Cantonment region. Whereas the ancient Paanpois were located on the outskirts of Pune. The aim of this paper is to study the evolution of the historic pyaavs and the paanpois which are regional expressions of water dispensing units from Pune. This study explores the tangible and intangible legacy through a variety of photographic documentation and a review of existing research in the topic, showcasing the individuality of each water dispensing unit.

Relationship of Physico-chemical Properties of Water with Phytoplankton Abundance in Peraru Village Tank in Vavuniya District

The village tank cascade system, predominantly found in the Vavuniya district, satisfies the water demand for agriculture and domestic needs considerably. Among them, the Peraru village tank lies in a cascade line in the Vavuniya district. The water resource of Peraru village reservoir is treated by the National Water Supply and Drainage Board, Vavuniya, and distributed to the local public. As Peraru a drinking water fountain, the study of phytoplankton and water quality is important. The study's objective was to identify the phytoplankton and estimate the abundance of phytoplankton in the Peraru village tank along with the Physico-chemical characteristics of water. A phytoplankton sampling was done by using plankton net at the selected three locations of Peraru village reservoir weekly from March to April 2021. Totally, 24 samples were analyzed during the study period. Simultaneously, water samples were also collected at each site to determine dissolved oxygen, electrical conductivity, pH, turbidity, temperature, nitrate, and phosphate concentrations. Identification of phytoplankton was made based on standard guides, and the abundances of phytoplankton were estimated using Sedgewick- rafter counting cells. The results of Physico- chemical parameters were statistically tested using ANOVA and found correlations between the abundance of phytoplankton and Physico-chemical parameters. Phylum Bacillariophyta and genus Aulacoseira were the dominant phylum and genus in the Peraru village tank. Dissolved Oxygen (DO), Electrical Conductivity (EC), nitrate, and phosphate positively influenced the abundance of phytoplankton in the Peraru village tank, while turbidity negatively affected the same.

Systematic Search for Water Fountain Candidates Using the Databases of Circumstellar Maser Sources

Water fountains (WFs) are thought to be objects in the morphological evolution of the circumstellar envelopes of low- and intermediate-mass evolved stars, transitioning from spherically symmetric to asymmetric shapes. We used databases of circumstellar 1612 MHz OH and 22.235 GHz H2O maser sources to search for new WF candidates using the criterion of a larger velocity range of the H2O maser emission compared to that of the OH maser emission. Thus, it is in principle possible to identify WFs with H2O velocity ranges smaller than those for the previously known WFs. For the OH maser line, we analyzed database entries of 8474 observations from 2195 sources, and 6085 observations from 3642 sources for the H2O maser line. After a close examination of the velocity ranges and line profiles, we identified 11 sources that meet the criterion mentioned above. We examined the IRAS colors of the selected sources and found that two of them (IRAS 19069+0916 and IRAS 19319+2214) are in the color region for post-AGB stars. We find that the maser velocity criterion can discover other astrophysically interesting objects than just WFs. Such objects may include peculiar planetary nebulae with maser emissions and stellar merger remnants.

FLASHING: Project overview

Abstract This paper describes an overview of the FLASHING (Finest Legacy Acquisitions of SiO-/H2O-maser Ignitions by the Nobeyama Generation) project promoted using the 45 m telescope of Nobeyama Radio Observatory, which aims to intensively monitor H2O (at 22 GHz) and SiO (at 43 GHz) masers associated with so-called “water fountain” sources. Here we show scientific results based on the data taken in the first five seasons of FLASHING, from 2018 December to 2023 April. We show the evolution of the H2O maser spectra, discovering new spectral components that break the record of the jet’s top speed and/or systematic velocity drifts in the spectrum indicating acceleration or deceleration of the maser gas clumps. For the 43 GHz SiO maser emission, we newly detect it in one source and find that it is no longer present in another source. This implies that the jets from these water fountains can be accelerated or decelerated, and show how circumstellar envelopes are destroyed.

Evaluation of Growth Performance, Efficiency of Dietary Net Energy Utilization, and Carcass Trait Responses of Heavy Finishing Lambs Administered 12 mg of Zeranol Subcutaneously in the Ear 59 d before Harvest

The objective of this research was to determine the influence of implanting heavy wether lambs with 12 mg of zeranol (1 pellet Ralgro, Merck Animal Health. Madison, NJ, USA) 59 d before harvest. Average daily gain (ADG), feed efficiency, and carcass merit were evaluated. Polypay and crossbred wethers (n = 32) were equally divided into two treatment groups: non-implanted; (CON) or implanted with 12 mg of zeranol (IMP) in a randomized complete block design. Sixteen pens were used, resulting in eight replicate pens per treatment. Wethers were fed a finishing diet consisting of cracked corn, soybean meal, and soybean hulls ad libitum for 59 d. Lambs had access to clean water at all times from water fountains. Lambs were weighed on d -1, 1, 14, and 59. On d 59, 16 lambs (8 lambs/treatment) were harvested in the South Dakota State University Meat Lab. Hot carcass weight (HCW), dressing percent (DP), rib fat, body wall thickness, loin eye area, boneless closely trimmed retail cut percentages, and yield grades were recorded. Final body weight (BW), cumulative ADG, and gain efficiency were greater (p ≤ 0.01) for implanted lambs by 2.9%, 25.0%, and 35.2%, respectively, while dry matter intake (DMI) was unaffected by implant treatment (p = 0.18); thus, the efficiency of dietary net energy utilization was increased for IMP (p ≤ 0.01). No appreciable differences were noted (p ≥ 0.17) between treatments for any carcass traits measured. These results indicate that zeranol improves growth performance in heavy finishing lambs without detriment to carcass quality, which implies that producers can improve profitability due to increased gains and efficiency.

Amperometric Determination of Hydrazine Using Au Nanoparticle Incorporated CMK-3 Modified Glassy Carbon Electrode

Abstract In this work, ordered mesoporous carbon (CMK-3) was synthesized using nano-casting method, in which Au nanoparticles were incorporated using citrate-reduction method. It was characterized using various physicochemical techniques like XRD, Raman, HRSEM, BET, and HRTEM. The synthesized material was utilized as an electrocatalyst for the electrochemical determination of hydrazine (HZ). From the cyclic voltametric studies, it is understood that the bare as well as CMK-3 modified glassy carbon electrodes fail to produce signal against hydrazine. On the contrary, Au nanoparticle incorporated CMK-3 modified glassy carbon electrode (AuNP-CMK-3/GCE) senses the analyte at the applied overpotential of 0.22 V. Using the amperometric measurements, it is concluded that the electrode is able to produce signal against the target analyte in the concentration range of 3 – 27 µM with the R2 value of 0.9964. Further, sensitivity and limit of detection (LOD) of the electrode against HZ were found as 0.00289 µA/µM and 1 µM, respectively. The selectivity of the electrode was examined in the presence of other interferrents, which revealed that the electrode is selective to HZ. The real-time applicability of the electrode was ascertained in the water samples collected from pond and water fountain.

Design of P-FLANN Model for Intelligent Water Fountain Sound Pleasantness Monitoring Using Bio-inspired Computing and Human Speech Perception

Cognitive-inspired Computational Computing systems play a crucial role in designing intelligent health monitoring systems which help both patients and hospitals. It also helps in early and consistent decision-making for various health issues including human psychological health. Water fountains built in parks and public spaces are used as decorative instruments which not only give appealing visuals but also it provides a relaxing environment to the visitors. These natural sounds have a direct effect on the psychological health of visitors. Very few research works are reported on developing the relationship between water sounds and their corresponding psychological impact. This assessment needs trained manpower and a lot of experimental time which is costly and may not be always available. In this paper to access the human health-friendly water fountain sounds from the pleasantness, a Perceptually Weighted functional link artificial neural network (P-FLANN) model is developed. To reduce the computational complexity of training and for faster convergence, swam intelligence-based optimization algorithm is used for updating the weights. It is observed from the comparative simulation results that the proposed P-FLANN model can effectively perform prediction tasks which is not only cost-effective but also 95% accurate and can play a crucial role in designing human health-friendly water fountains in smart cities.

Investigating water safety in multi-purpose buildings used as an elementary school and plumbing remediation effectiveness

Three buildings that were repurposed for use as an elementary school were shutdown for three months in response to the pandemic. Building cold and hot water quality was monitored before reopening to detect and resolve chemical and microbiological problems. The authors collected first draw pre-flush and post-flush water samples. First draw water samples did not contain detectable disinfectant residual, but nickel and lead sometimes exceeded the health-based action limits for cold water (max. 144 μg Ni/L, 3.4 μg Pb/L). Stagnant cold water at a bathroom sink (188 MPN/100 mL) and drinking water fountain (141.6 MPN/100 mL), in the same building, exceeded theL.pneumophilathresholds advised by the World Health Organization (WHO) (10 CFU/mL) and American Industrial Hygiene Association (AIHA) (100 CFU/mL). Fixture flushing was conducted to remove cold and hot stagnant water and noL.pneumophilawas detected immediately after flushing. Two weeks after no subsequent building water use, chemical and microbiological contaminant levels were found to be similar to levels prior to flushing with one exception. The maximumL.pneumophilalevel (kitchen sink, hot water: 61.1 MPN/100 mL) was found in a different building than the prior maximum detections. No repeat positive locations forL.pneumophilawere found during the second visit, but new fixtures were positive the organism. When this study was conducted no evidence-based guidelines for plumbing recommissioning were available. A single plumbing flush reduced heavy metal andL.pneumophilalevels below WHO and AIHA thresholds in all three buildings. Additional work is needed to examine the role of building size, type and plumbing design on fixture water quality in shutdown buildings.

Saving natural resources is something that is very necessary today, both in the household environment and in the wider environment. The use of reservoirs or commonly called water fountains used to hold water can reduce the use of electrical energy and provide a sustainable water supply. The use of this automatic toren also has a considerable contribution in saving water when a person's level of care is not good. To find out the water level in the reservoir is very difficult to do manually. While the location of the water reservoir is very difficult to reach. So that when the water reservoir is full, there is often water overflowing or exceeding the height limit of the reservoir, and if there is no warning system if the water flow is disturbed. Thus there is a waste of water resources. The sound sensor serves as a marker when the water reservoir has overflowed or exceeded the height limit of the water reservoir. In this study, it was examined how effective the sound sensor is in providing signs or warnings to objects / humans

In this brief review, the focus on university infrastructure and environmental sustainability is apparent, coupled with a review of the tools for success after interventions in children's schools. Given the great overall interest in fluid intake guidelines for public health, higher education campuses should implement policy and infrastructure changes to increase the number of drinking fountains on campus.

Evolution of the Outflow in the Water Fountain Source IRAS 18043–2116* *Released on 2021 March 1.

We present the spectral and spatial evolution of H2O masers associated with the water fountain source IRAS 18043−2116, found in observations with the Nobeyama 45 m Telescope and the Australia Telescope Compact Array. We have found new highest-velocity components of the H2O masers (at the redshifted side V LSR ≃ 376 km s−1 and at the blueshifted side V LSR ≃ −165 km s−1), and the resulting velocity spread of ≃540 km s−1 breaks the speed record of fast jets/outflows in this type of sources. The locations of those components have offsets from the axis joining the two major maser clusters, indicating a large opening angle of the outflow (∼60°). The evolution of the maser cluster separation of ∼2.9 mas yr−1 and the compact (∼0.″2) CO emission source mapped with the Atacama Large Millimeter-submillimeter Array suggest a very short (∼30 yr) timescale of the outflow. We also confirmed an increase in the flux density of the 22 GHz continuum source. The properties of the jet and the continuum sources and their possible evolution in the transition to the planetary nebula phase are further discussed.

Eco-City-Based Sustainable Settlement Planning In Bengkayang New City Area

The inability of a city to the pressure of increasing activity in urban areas which has encouraged the expansion of development into suburban areas is a phenomenon that often occurs in major urban centers. With the development of a new area, it can be a solution to solving urban problems, expanding the availability of housing and infrastructure, and reducing disparities between the main city and suburban areas. The development of a new city, in addition to physically changing the suburban area, can also have a socio-economic impact on the people, as a challenge to fulfill the welfare of the urban housing phenomenon. Bengkayang Regency is one of the developing districts. As one of the border frontier cities in West Kalimantan Province, Indonesia, Bengkayang is the main border gate between Indonesia and neighboring Malaysia and Brunei Darussalam. The great potential of Bengkayang Regency has not been supported by adequate urban planning and arrangement, which can reflect unique regional characteristics (local wisdom). The local government has established a policy regarding the development of a new city in Bengkayang, which is located in the Bumi Sebalo Village. This study aims to carry out sustainable settlement planning in the New City Area of Bengkayang based on Eco-City. Determination of the location based on the new Bengkayang city master plan data, namely in the sub BWP housing and green open space, with a descriptive qualitative analysis method. Settlement planning carried out includes aspects of housing, area support facilities and public green open spaces. The direction for housing arrangement uses a balanced residential concept, with a cluster system without guardrails, a grid pattern following the contours and condition of the land, pedestrian-friendly, and utilizing natural potential in the form of river flows as public open space areas and jogging tracks. Commercial facilities as supporting areas are placed on main road access with more strategic functions. Public green open space as a means of socializing and recreation on a city scale, how many sub-BWP green open spaces are equipped with urban forests as bearers of ecological functions, playgrounds, water fountains, amphitheater, street vendor areas to support the local community's economy, festival market areas as well as several tourist and cultural attractions as support activity.

Microbiological water quality and derived health risks from exposure to ornamental water fountains in the city of Hannover.

Ornamental fountains are attractive urban infrastructures helping cities to cope with global warming, as water sprays have great cooling effects due to evaporative properties; however, exposure to microbiologically impaired water from ornamental fountains during recreational activities may result in adverse health outcomes for the exposed population. This study assesses the microbial water quality of four ornamental water fountains (Blätterbrunnen, Körtingbrunnen, Klaus-Bahlsen-Brunnen, and Marstallbrunnen) and performs a quantitative microbial risk assessment (QMRA) for children using Escherichia coli, Enterococci, and Salmonella to quantify the probability of gastrointestinal illnesses and Pseudomonas aeruginosa to quantify the risk of dermal infections. Samples were collected fortnightly in two campaigns in 2020 and 2021 and processed to determine bacterial concentrations. Data on exposure time were obtained during field observations on the selected fountains; a total of 499 people were observed of which 30% were children. Mean bacterial concentrations ranged from 1.6×101 to 6.1×102 most probable number (MPN)/100mL for E. coli, 1.2×101 -1.2×103 MPN/100mL for Enterococci, 8.6×103 -3.1×105 CFU/100mL for Salmonella, and 2.5×103 -3.2×104 MPN/100mL for P. aeruginosa. The results of the QMRA study showed that the USEPA illness rate of 36 NEEAR-gastrointestinal illnesses/1000 was exceeded for Enterococci at the Körtingbrunnen, Klaus-Bahlsen-Brunnen, and Marstallbrunnen fountains and for Salmonella and P. aeruginosa at the Körtingbrunnen fountain, suggesting that exposure to microbiologically contaminated water from ornamental fountains may pose a health risk to children. The scenario analysis shows the importance of keeping low bacterial concentrations in ornamental fountains so that the risk of illness/infection to children does not exceed the USEPA illness rate benchmark.
