The plants will receive organic Aquaponic technology is a combination of aquaculture technology and hydroponic technology in one system to optimize the function of water and space as a rearing medium. The plants will receive organic fertilizer automatically from the remaining feed and fish waste. The advantage of using aquaponic cultivation is that plant nutrients can be obtained from feces and leftover fish food that settles at the bottom of the pond, so that quality water is produced that meets standards for fish farming. The stability of dissolved oxygen in water will be obtained from a water recirculation system in the form of a shower that results in collisions with pool water. In addition, the production of plants cultivated with the aquaponic system will be better than conventional because of the availability of sufficient water and additional nutrients from fish feces and food scraps.

Prevalence of diarrheal disease and associated factors among under-five children in flood-prone settlements of Northwest Ethiopia: A cross-sectional community-based study.

Diarrheal illnesses are a long-standing public health problem in developing countries due to numerous sanitation issues and a lack of safe drinking water. Floods exacerbate public health issues by spreading water-borne infectious diseases such as diarrhea through the destruction of sanitation facilities and contamination of drinking water. There has been a shortage of studies regarding the magnitude of diarrheal disease in flood-prone areas. Therefore, this research aimed to evaluate the prevalence of diarrheal disease and its predictors among under-five children living in flood-prone localities in the south Gondar zone of Northwest Ethiopia. A community-based cross-sectional research was carried out in flood-prone villages of the Fogera and Libokemkem districts from March 17 to March 30, 2021. Purposive and systematic sampling techniques were used to select six kebeles and 717 study units, respectively. Structured and pretested questionnaires were used to collect the data. A multivariable analysis was performed to determine the predictors of diarrheal disease, with P-value <0.05 used as the cut-off point to declare the association. The prevalence of a diarrheal disease among under-five children was 29.0%. The regular cleaning of the compound [AOR: 2.13; 95% CI (1.25, 3.62)], source of drinking water [AOR: 2.36; 95% CI: (1.26, 4.41)], animal access to water storage site [AOR: 3.04; 95% CI: (1.76, 5.24)], vector around food storage sites [AOR: 9.13; 95% CI: (4.06, 20.52)], use of leftover food [AOR: 4.31; 95% CI: (2.64, 7.04)], and fecal contamination of water [AOR: 12.56; 95% CI: (6.83, 23.20)] remained to have a significant association with diarrheal diseases. The present study found that the prevalence of the diarrheal disease among under-five children was high. Routine compound cleaning, the source of drinking water, animal access to a water storage site, vectors near food storage sites, consumption of leftover food, and fecal contamination of water were significant predictors of diarrheal disease. Therefore, it is advised to provide improved water sources, encourage routine cleaning of the living area, and offer health education about water, hygiene, and sanitation.

Restaurant customers' food leftover reduction intention derived from nature connection and biospheric values: A comparison between men and women.

As the COVID-19 pandemic extends over a long period of time, the World Food Programme (WFP) estimated that food insecurity would take place in the near future. Previous studies focused on various kinds of interventions for food waste prevention. Surprisingly, however, research tackling consumer attitudes and behaviors as a way to reduce food waste is still rare. To fill this gap in the literature, this study examined the antecedent roles of restaurant customers' nature connection and biospheric values in fostering their food leftover reduction intention through environmental self-identity and sense of obligation to reduce food leftover. In addition, the moderating effects of gender were tested on all the relationships in our conceptual model. A quantitative approach with an online survey for restaurant customers was adopted. Structural equation modeling was adopted to analyze the data. Through confirmatory factor analyses, the adequate reliability and validity of the measures were established. All the relationships between the constructs were found to be significant, supporting the hypotheses. In other words, the restaurant customers' nature connection and biospheric values were found to eventually induce the customers' food leftover reduction intention. In addition, in terms of the moderating effect, the male customers' nature connection more strongly increased their biospheric values than the female customers' case. The findings of this study revealed how restaurant customers' food leftover reduction intention is formed through their feeling of oneness with nature and biospheric values. Given that consumer behavior has been recognized as a major driver of restaurant food waste, the findings of this study provide useful insights to restauranteurs and policymakers for the health of society and people in it. It was especially true for men in that their feeling of oneness with nature significantly influences their biospheric values more than women's.

Meal satisfaction analysis of patients at RSUD dr. H. Abdul Moeloek Lampung province

Patient eating satisfaction is an indicator of the success of organizing food in the hospital. One way to evaluate the success of organizing a patient's meal is from the remaining food. Currently, there are many hospitals with leftover food from patients that exceed the established standards. The aim of the study was to analyze the food satisfaction of inpatients with leftovers at hospital of dr. H. Abdul Moeloek, Lampung Province. This type of analytic observational research with a cross sectional design. The number of samples in this study were 66 people. The chi-square test was used to analyze the relationship between patient satisfaction and food waste. There is a relationship between taste (p=0.000), time of distribution (p=0.028), and the appearance of the waitress (p=0.028) and food waste, and there is no relationship between the completeness of cutlery and food waste (p=0.095). This study shows that there is a significant relationship between the taste, time of distribution, and the appearance of the waiter with leftovers, but not the completeness of cutlery. It is recommended that the Nutrition Installation of dr. H. Abdul Meoloek Hospital conduct an evaluation to improve the taste of food, the right time of distribution, the appearance of better waiters.

Syngas production from thermochemical conversion of mixed food waste: A review

AbstractLately, the generation of leftover food or cooked food waste has turned out to be a critical issue and its disposal in an environmental friendly way has been a challenge. This food waste is being sent for incineration and landfilling which results in a significant contribution to environmental pollution. Therefore, alternative methods for processing food waste in an environmentally benign way have been explored by many researchers. Thermochemical methods are one of those methods and are found to be promising for not only handling the food waste in an ecological way but also producing renewable energy efficiently in the form of bio‐oil and syngas along with a solid byproduct, that is, biochar. However, the generation of syngas is favored by only two thermochemical processes, fast pyrolysis, and gasification. Some derived processes such as co‐pyrolysis, and co‐gasification can also generate syngas. All these processes for syngas generation differ from each other in terms of process conditions (temperature, reaction agents, and residence time) and syngas quality generated (amount of syngas produced, syngas composition, and heating capacity). Additionally, supercritical water gasification is the latest process developed for processing food waste to generate syngas with much higher hydrogen fraction; however, it produces syngas with less yield and involves high operational costs.This article is categorized under: Sustainable Energy &gt; Bioenergy Emerging Technologies &gt; New Fuels Sustainable Development &gt; Energy‐Water‐Food Nexus

ВЛИЯНИЕ РАЗВЕДЕНИЯ ЛОБСТЕРОВ В ЗАЛИВЕ СУАН ДАЙ, ПРОВИНЦИИ ФУЙЕН НА СОЦИАЛЬНО-ЭКОНОМИЧЕСКУЮ И ЭКОЛОГИЧЕСКУЮ ОБСТАНОВКУ

Xuan Dai Bay, province Phu Yen has diverse biot and high species richness. This is a favorable condition for the development of aquaculture with high-value farming species such as lobster, cobia, grouper... Based on the history of aquaculture and enviromental conditions, the Provincial People's Committee of province Phu Yen planned to develop Xuan Dai Bay into a key aquaculture area for high-quality seafood (lobster). Research results show that lobster farming operations in the area are very crowded and growing rapidly. Lobster farming has made a significant contribution to the socio-economic development of the area in recent years through larval fishing, fresh food supply, and lobster trade. Lobster farming has clearly changed the face of the countryside, creating many jobs, increasing incomes and improving the lives of people in the area. However, leftover food is dumped directly into the bay, which is one of the causes of environmental pollution. At all sampling stations, the content of total organic carbon in bottom sediments is high. It varies widely between sampling stations and tends to be high in the interior of the bay. The average value is 51.21±11.85%, ranging from 26.68% to 62.12%. These organic substances decompose, causing changes in the structure of sediment particles, reducing the amount of dissolved oxygen in water and sediment and even, under severe hypoxic conditions, promoting a series of anaerobic reactions, creating toxins for living organisms.

Litter buffet: On the use of trash bins by birds in six boreal urban settlements

Unintentional food resources in urban areas (street litter, food leftovers, overflowing trash bins) are dietary components of some urban-exploiter bird species. In this study, we report on 13 bird species in six southern Finnish cities using urban trash bins and describe differences in their activity when provided with food resources (i.e., bait) in different bin types. We used generalized linear models (GLM) and classification and regression trees (CART) to test for associations between environmental variables and bird activity at the binscapes. Bird activity at the binscapes significantly differed among all cities and among types of bins and was significantly higher after placing bait in all cases. Bins with the largest opening had more activity as opposed to those with smaller openings or lids. Corvids and gulls had the highest activity, with corvids usually being present before the bait was placed and gulls increasing their activity thereafter. These differences show that trash bin foraging is highly malleable and thus susceptible to management preventing its occurrence. Suitable waste management measures could aid in reducing the number of species close to bins and their surroundings, benefiting both bird and human health.

Influence of the autochthonous cellulolytic bacteria on the domestic compost process improvement.

This work aimed to determine the influence of the inoculation of autochthonous cellulolytic bacteria on the composting process without any modifications of physical or chemical parameters. Bacteria with cellulolytic abilities were isolated from composted material containing food and plant leftovers and identified as Bacillus licheniformis, Bacillus altitudinis, and Lysinibacillus xylanilyticus. The experimental composter containing garden and household wastes was inoculated with bio-vaccine prepared as a mixture of isolated cellulolytic bacterial strains and composted for the next 96 days parallelly to the control composter without the inoculation. During the experiment, changes in temperature, humidity, the content of the humic acids (HAs), organic carbon, nitrogen, and C : N ratio were determined. As the particular microbial groups play a key role in the composting process, the biodiversity of the microorganisms present in the composter as well as the number of psychrophilic, mesophilic, and sporeforming microorganisms, Actinomycetes, and fungi were analyzed. The changes in the abundance of particular bacterial groups were convergent with temperature changes in the temperature of composting material. The composting material inoculated with autochthonous microorganisms was characterized by higher HA content and lower biodiversity. The inoculation with autochthonous microorganisms positively influenced the composting material in the corners for the entire process and in the middle of the container for 61 days. Thus, the effect of inoculation depended on the localization of the process inside the container subjected to biopreparation.

Influence of Organic Waste on Nutrient Composition of Compost and the Impact of Sawdust on Composting Process.

To improve soil health and fertility use of compost is a better idea than chemical fertilizers. Compost is a product of the degradation of waste organic matter. The choice of organic waste to get a good quality of compost is needed for the proper recycling of organic waste. So, the present study was to identify the effect of the type of organic waste on the physical properties and nutrient content of compost. The experiment was conducted with four types of organic waste (Fruit waste, vegetable waste, cooked leftovers, and farm waste). The analysis shows that type of organic waste in composting influences the nutrient content of compost but the physical properties of compost are not much affected by the type of organic waste. It was observed that waste from cooked leftover food contains more nutrient content than other waste. So this waste is more suitable for composting. During the study effect of sawdust as a bulking agent was also observed. Sawdust significantly affects the composting process as it accelerates composting and also affects the quality of compost.

LIFE ON THE STREETS IS HORRIBLE: OLDER RURAL-URBAN MIGRANTS COPE WITH HOMELESSNESS IN ETHIOPIA

Abstract The prevalence of homelessness among older adults in Ethiopia is growing. While prior studies examined the push factors and challenges of homeless elders, little is known about how older people in Sub Saharan Africa cope with homelessness. This study explored the coping strategies of homeless older people in Kobo Town, Ethiopia. Purposive sampling was used to identify 10 homeless older people and four key informants. Study participants were homeless for a year or longer. Thematic analysis was used to analyze the data collected through in-depth interviews. To cope with the challenges faced on the street, homeless older people used various strategies including begging, holy water, drying leftover food, using river water for hygiene and sanitation, sleeping in church compounds, and creating their own social networks. Despite their efforts, the coping strategies used by elders were not sufficient. In the absence of family and government support, study participants relied heavily on begging to meet their survival needs. The findings call attention to the need for a national income support program and other supportive services for older adults. Homelessness is the product of a failing support system. Despite Ethiopia having a Plan of Action for Older Persons and Social Protection Policy for Vulnerable Groups, these policies have not been effectively implemented leaving older adults with no safety net. This study calls for the development of new policies to empower older people in Ethiopia and prevent them from turning to begging as their only recourse.

The Relationship of Food Leftovers and Students' Level of Satisfaction with the Food Served with the Nutritional Status of Nurul Ulum Islamic Boarding Students in Peureulak, East Aceh

Nutritional status is a condition determined by the degree of food whose physical impact can be measured. Adolescents are a group that is vulnerable to experiencing nutritional problems. The prevalence of wasting among adolescents aged 16-18 years nationally is 9.4% (1.9% are very thin and 7.5% are thin). The prevalence of adolescent nutritional status in Aceh among adolescents aged 16–18 years is 7.3% thin, 12.6% fat, and 4.6% obese. Good nutritional status must be balanced with incoming and outgoing energy and protein intake. One way to measure a person's food intake is by weighing food waste. This research is descriptive and analytical in nature, using a cross-sectional approach with a total sampling of 60 people carried out in February 2019 at the Nurul Ulum Islamic Boarding School, Peureulak, East Aceh. The research variables are food waste with nutritional status and level of satisfaction with nutritional status. Descriptive data analysis included frequency distribution and percentages with the Chi-square test. The results of this study showed that 42 people (70.0%) had a normal BMI, 10 people were thin (16.7%), and 8 people were obese (13.3%). The results of female students' food waste show an average of 20.1%. Most of the female students at the Nurul Ulum Islamic Boarding School in Pereulak, East Aceh, had a lot of food leftovers, 35 people (58.3%) and 25 people (41.7%) a little food waste, and for this category, the level of satisfaction showed that the average was 68.9 The majority of those who were dissatisfied were 45 people (75%), and those who were satisfied were 15 people (25%). The results of this research concluded that there was a relationship between food waste and the nutritional status of female students at the Nurul Ulum Islamic Boarding School, Pereulak, East Aceh, marked with a P value of 0.023 or (P&lt;0.05), while the relationship between female student satisfaction and the nutritional status of female students at the Nurul Ulum Islamic Boarding School, Pereulak Aceh East there is no relationship indicated by a P value of 0.921 or (P&gt;0.05).

Evolving technology and new paradigms in analytical sciences. A sustainable solution for degradation of biodecomposable waste - a hybrid model

The accompanying processes of economic progress, such as growing urbanisation, industrialisation, and changes in lifestyle patterns, result in increased waste production and environmental hazards. Technology advancements in recent years have made it possible to safely dispose of waste while also producing a significant amount of decentralised energy. The goal of the current study was to examine the vermicomposting of kitchen waste and food scraps into garden manure using earthworm species, “Eiseniafetida” - “Vermigold” (a name coined by the authors), as well as microorganisms such as Lactobacillus acidophilus, Lactococcus lactis, Lactococcus lactis cremoris, etc. Two different feedstocks were prepared with varying dosages of the The findings indicate that the vermicompost's NPK content increased dramatically. In the current study, these microorganisms are compared in the presence of earthworms on green substrates (kitchen trash), and a parallel investigation using leftover food is also conducted.

Detection of chlorinated organic pollutants with an integrated screen-printed electrochemical sensor based on a carbon nanocomposite derived from bread waste

Halogenated organic compounds are ubiquitous in water bodies due to anthropogenic activities and some of them pose a real threat to the aquatic environment and human health. That is the case of artificial sweeteners such as sucralose and haloacetic acid disinfection byproducts such as trichloroacetic acid (TCA), classified as contaminants of emerging concern. This motivates the search for rapid, cost-effective and easy-to-use analytical tools that could be deployed to facilitate the analysis of organohalide pollutants and aid in accurately monitoring water quality. This work explores the rapid detection of sucralose and TCA using a very simple miniaturized sample-to-result integrated electrochemical sensor. The device incorporates a screen-printed three-electrode electrochemical cell (SPE) where the working electrode is made of a nanocomposite of Ag nanoparticles and porous C (Ag/C). The material is prepared from bread waste, in an attempt to add value to one of the largest fractions of food leftovers and thus contribute to the sustainable circular economy. The electrochemical process behind the sensor analytical performance is initially evaluated using free Cl− ions in solution and then, the sensor is used to analyze the mentioned target analytes. A paper disk integrated over the electrode area and loaded with the reagents required for the sample conditioning makes the analysis straightforward. The sensor thus produced can be inserted in a highly compact low-power instrument connected to a mobile phone, making an easy-to-use device suitable for on-site analytical studies.

Tetrodotoxin Intoxications in Nagasaki, Japan: Symptoms of Patients, Tetrodotoxin Levels in Leftover Food and Clinical Urine and Serum Samples

Incidents of food poisoning associated with tetrodotoxin (TTX) contamination occur every year throughout Japan. Here, we determined TTX levels in leftover foods and serum and urine samples from eight food poisoning incidents associated with TTX contamination in Nagasaki, Japan, from 2011 to 2017.Seven food samples associated with four of these food poisoning incidents were classified as weakly toxic (four samples), moderate-to-strongly toxic (two samples), and strongly toxic (one sample).In comparison with previous reports, TTX was detected at harmful levels in the urine samples, but the grade of poisoning symptoms varied.The patients' time to maximum serum TTX levels (Tmax) was estimated to be 12-24 h after ingestion of TTX-containing foods. Additionally, serum TTX levels of 19.5 ng/mL or higher within 24 h after ingestion indicated Grade 3 poisoning associated with respiratory abnormalities.These conditions were considered indicators of severe symptoms, while TTX levels of 1-3 ng/mL relate to the onset and disappearance of symptoms. A negative correlation was found between the logarithm of serum TTX concentration and the time after ingestion for two patients, indicating that the TTX serum levels decreased logarithmically. Furthermore, the TTX serum half-lives (T1/2) were 17.5 and 23.7 h.The results of this study enhance our understanding of TTX food safety and contribute to TTX risk assessment.

Ophthalmomyiasis in a preterm neonate resulting in blindness: A case report from Botswana

Myiasis is an infestation of human tissue by insect larvae. While rare, healthcare-associated myiasis has been reported from immobilized patients in resource-limited healthcare facilities in warm climates without adequate vector control measures. We describe a case of Ophthalmomyiasis in a hospitalized neonate in Botswana that resulted in vision loss. The neonate, who was initially hospitalized due to the complications of prematurity, received phototherapy for jaundice, and to avoid phototherapy-related retinopathy, the neonate’s eyes were covered using cotton gauze and adhesive tapes that potentially damaged the skin as commercially available eye covering was not in stock. Therefore, eye covering was not changed and when the eye covering was removed almost 3 days after placement, insect larvae were noted in the patient’s eyes and nose. Ophthalmologic evaluation revealed perforated corneal ulcer and uveal prolapse in the right eye resulting in complete blindness and corneal scarring of the left eye. The patient’s clinical course was further complicated by an Enterobacter species bloodstream infection. This case highlights the importance of vector control as a major patient safety measure for neonatal units in warm climates. Flies had been observed in the room and mitigation measures included reducing fly populations through traps, screens, and removal of standing water and leftover food. Every mother and staff were sanitizing hands when entering the room and gowns were used. This case also reinforces the importance to conduct vigilant monitoring of patients, especially neonates with eyes covered during phototherapy.

PSVI-13 Nutritional Supplementation with Leftover Food of Dairy Cows Upon Reproductive Response of Goats

Abstract To evaluate the effect of nutritional supplementation with leftover food of dairy cows upon the reproductive response of multiracial female goats fed in open range in northern Mexico (26°N, 104°W), 38 multiparous goats in extensive grazing conditions were randomly assigned to two groups with similar weight (BW; Kg) and body condition score (BCS; scale 1-5). The control group (CG; n=19; BCS 1.7± 0.03; BW 60.42 ± 1.5 Kg, fed only in native vegetation) and supplemented group (SG; n=19; BCS; 1.7± 0.07; BW 60.21± 0.97 Kg) were fed native vegetation plus a nutritional supplementation with a ration fully mixed of leftover dairy feed, which consisted of 96.67 g of corn silage, 54.08 g of alfalfa ground hay, 49.38 of soybean paste, 37.80 g of cottonseed, 124.27 g of rolled corn and 37.80 g of commercial mixture with vitamins and minerals (totaling 400g; 14.5 PC,80% DM). The diet was offered individually daily (before grazing) from day -5 to +15 of the study. All females were subject to the male effect (Day 0; 2/group) for 10 days. By transrectal ultrasonography (Aloka SSD-500; 7.5MHz) were determined: the proportions of females having ovulations (OF: day 8) and pregnant females (PF, day 45). All data were compared using a Chi-square test (IBM SPSS 25). Differences were observed (P&amp;lt; 0.05) for OF (SG:15/19;78.9% vs CG: 9/19; 47.3%), but not for PF (SG:10/19; 52.6% vs CG: 6/19; 31.5%). We conclude that the proportion of ovulating females was greater n SG than in CG, nevertheless, the PF was not different, possibly because the time in which the nutritional supplementation was offered did not influence the period of embryonic implantation, it would be interesting to do an experiment extending the period of nutritional supplement with leftover food.

Tableware Tidying-Up Robot System for Self-Service Restaurant-Detection and Manipulation of Leftover Food and Tableware.

In this study, an automated tableware tidying-up robot system was developed to tidy up tableware in a self-service restaurant with a large amount of tableware. This study focused on sorting and collecting tableware placed on trays detected by an RGB-D camera. Leftover food was also treated with this robot system. The RGB-D camera efficiently detected the position and height of the tableware and whether there was leftover food or not by image processing. A parallel arm and robot hand mechanism was designed to realize the advantages of a low cost and high processing speed. Two types of rotation mechanisms were designed to realize the function of throwing away leftover food. The effectiveness of the camera detection system was verified through the experiments of tableware and leftover food detection. The effectiveness of the prototype robot and the rotation assist mechanism was verified through the experiments of grasping tableware, throwing away leftover food by two types of rotating mechanisms, collecting multiple tableware, and the sorting of overlapping tableware with multiple robots.

CORRELATION BETWEEN BODY WEIGHT AND ORGAN WEIGHT IN DIGESTIVE SYSTEM OF NORTH SULAWESI LOCAL PIG

North Sulawesi local pigs have good potential because they have a high adaptability to the environment and low-quality feed obtained from processed food remnants of the population. The samples used in this study were local sows from North Sulawesi which were spread on traditional farms. The purpose of this study was to obtain data on body weight of livestock including the weight of organs in the digestive system (stomach, intestine and liver). Body weight data will be correlated with organ weight and intestinal length data. The results showed that the average body weight of the local pigs used in this study ranged from 16.65 ± 0.66 kg with the age of the cattle ranging from 1 year. The results of statistical analysis of the correlation test between body weight and organ weight of local pigs showed a very significant correlation value (P &lt; 0.01). The correlation value shown in the study shows a very strong value in the correlation between body weight and the weight of an empty stomach and a strong correlation value is shown in the correlation between body weight and liver weight and intestine length, meaning that the weight of organs in the body in the digestive system will increase with increase in body weight. Body weight is one indicator of livestock productivity that can be estimated based on the size of the animal's body.

Predictors of Reuse and Donation Intentions of Leftover Food items: an Empirical Analysis

The recent estimates points that around 30% of food gets wasted globally along the food supply chain, household food wastage accounting to nearly half of it. With the unprecedented growth in population, it is expected that by 2050 there will be a 70% increase in the demand for food (FAO, 2017). Therefore, there is a need to understand factors that may reduce the food wastage among households. The data was gathered from 260 Indian female respondents aged between 18 and 65 years who were responsible for their household chores. Structural equation modelling was applied for the analysis. Findings showed that religiosity significantly affects both moral norms and concern for community. Moral norms, subjective norms, concern of community are significant predictors of attitude towards reduction of food wastage whereas attitude towards reduction of food wastage leads to its reuse and donation. However, environmental literacy does not have any significant impact on attitude towards reduction of food wastage.
