<p>Soft shell crab farming has been practiced in south-east Asian countries such as Indonesia. Soft shell crabs are harvested when they have just molted to prevent their shells from being hardened. An issue arises when feeding the crabs. Farmers need to feed the crabs 5% food of their body weight. However, farmers sometimes provide incorrect amounts of food to the crabs. If farmers feed the crab exceeding the required amounts of food, it causes food wastage and dirty water in the crabs’ cage. On the other hand, less amounts of food causes slow growth and molting of the crabs. In this study, we developed an automated feeding system for properly feeding of soft-shell crabs. The automated feeding system schedules the feeding time and controls the portion of food using a microcontroller. We also developed a web-based monitoring system to monitor and generate alert message to farmers to make sure that feeding process runs properly.</p>

Hungers in the world are burning issue now-adays and wastage of food is increasing day by day. Surplus Food for Orphanage (SFO) is an online food management system that manages extra food for starving people who have not enough food to remain alive. The aim of the research is to develop a web-based portal named “Surplus Food for Orphanage” which makes a communication between donor and food seeker. This paper represents a new internet-based website that will be helpful for donating old stuff and extra food to all needy people. In this website the donor can register his/her account. When registration becomes successful, donor can access this website by log in to their account. Donor will publish their post by enrolling their food item’s name, quantity of food that donor want to donate, their contact number and location also. A simple notification is given to the admin. Charity can view the donor/restaurant post by logging in to this website. Then charity can contact to the food donor and collected the surplus food from donor and collected food will be distributed to the disadvantaged people. This system will be helpful to reduce the wastage of food, inspiration for the donor to come forward to donate foods for orphanage easily.

Control And Monitoring System

The livestock farming sector usually require a lot of manpower and may face problems such as adhering the designated feeding schedule. Therefore, this paper intends to aid in this sector by bringing the smart feeder system. The main objective of this paper is to control and monitor livestock feeding time using application via smartphones. This is to ensure that the livestock are fed according to the right schedule. This paper also highlighted the advantage of the smart feeder system where it can be used to save up money and energy that can be obtained by having less labor workers. This is because of the hopper storage that can accommodate the food up to three days. The importance of this system is its ability to automate the feeding system for the livestock. The smart feed system designed is different from the existing livestock feeding machines that are available anywhere in the market due to the implementation of Internet of Things (IoT) in the system. The usage of IoT allows farmers to set the feeding schedule automatically by using an application via smartphone. Besides, users will also be informed on the weight of food in the storage and food container through the application. This will allow the users to monitor the food storage and only come to refill it when it is empty. Farmers can also observe whether the livestock have eaten or not by getting updated on the level of food of the food storage using an ultrasonic sensor.

Background: Sexual intercourse is one of the important components of well-being, especially in married couples. There is a dearth of baseline research and data regarding the sexual habits of residents in South-East Asia. Objective: We aimed to see the baseline frequency of sexual intercourses among the residents of 3 South Asian countries (Bangladesh, India, and Nepal). Methods: This web-based cross-national, cross-sectional study was done among the residents of Bangladesh, India, and Nepal through Google forms. Married individuals who were living with their spouses were invited to respond to the survey. Results: A total of 120 respondents participated in this survey of which 46.7%, 38.3%, and 15% of respondents were from India, Nepal, and Bangladesh, respectively. The mean of the weekly sexual intercourse was 2.23 (range: 0-8) among the total respondents; 2.70 (range: 0-7) among the Nepalese, 2.32 (range: 0-5) among the Bangladeshis, and 1.82 (range: 0-8) among the Indians. The differences were not statistically significant. Conclusion: This study revealed very baseline and preliminary excerpts of sexual intercourse habit among the residents of 3 South Asian countries. There is a geographical variation in regard to the sexual contacts. Further, large-scale well-designed studies are warranted to explore the behavior.

AbstractThe African turquoise killifish is an exciting new vertebrate model for aging studies. A significant challenge for any model organism is control over its diet in space and time. To address this challenge, we created an automated and networked fish feeding system. Our automated feeder is designed to be open-source, easily transferable, and built from widely available components. Compared to manual feeding, our automated system is highly precise and flexible. As a proof-of-concept for the feeding schedule flexibility of these automated feeders, we define a favorable regimen for growth and fertility for the African killifish and a dietary restriction regimen where both feeding time and quantity are reduced. We show that this dietary restriction regimen extends lifespan in males. Moreover, combining our automated feeding system with a video camera, we establish an associative learning assay for the killifish. This learning assay provides an integrative measure of cognitive decline during aging. The ability to precisely control food delivery in the killifish opens new areas to assess lifespan and cognitive behavior dynamics and to screen for dietary interventions and drugs in a high-throughput manner previously impossible with traditional vertebrate model organisms.

Summary In a total mixed ration (TMR) feeding system, lambs, as well as other animals, tend to exhibit dietary preferences. The purpose of this paper is to examine differences in the feed selection behavior between lambs previously accustomed to TMR feeding and lambs newly introduced to TMR diets. A total of eight male Suffolk lambs were allocated to two groups of four each. Both groups received the same feed formulation. The roughage portion of the diet consisted of alfalfa hay, whereas the concentrate portion included a concentrate mixture for finishing lambs. One group of lambs was fed total mixed rations containing 30% alfalfa hay and 70% pelleted concentrate. The other group received alfalfa hay and concentrate rations separately as single diets. Diet selection measurements were performed after four weeks of the experimental feeding regime. The results obtained indicate a clear preference of both groups for concentrate (112±5% and 110±6% respectively) over alfalfa hay (72±11% and 77±14% respectively). Significant differences were recorded in the duration of feeding time. The lambs accustomed to TMR feeding consumed 400 g of TMR for 18±1 minutes, whereas the lambs newly introduced to TMR diets required 154±88 minutes for the same allotment. Moreover, the lambs starting on a TMR diet were found to consume feed markedly slower, although their diet selection proved equally successful compared to the lambs accustomed to TMR feeding.

Step feeding flow configuration is an attractive process alternative for large treatment systems designed for nitrogen removal, eliminating the need for internal recycling and optimizing organic carbon utilization for denitrification. Volume ratios of anoxic and aerobic volumes and wastewater fraction to be diverted from the inlet of the system are important parameters to be considered in the design of the step feeding process. Wastewater characterization and especially C/N ratio significantly affect the design. The effect of wastewater characterization is illustrated for the Riva Plant in Istanbul, with a capacity of 4 million population equivalent, designed as a two-stage step feeding system for biological nutrient removal. It is shown that the proposed design cannot meet the effluent standard of 10 mgl−1 total N for the relevant sewage characterization assessed on the basis of an extensive experimental study, totally different from the one adopted for design.

AbstractChanges in the formulation and flavour of concentrate foods may temporarily reduce their acceptability to cattle, leading to reduced intake when they are offered for a limited time during milking. The rate of intake of 12 dairy cows offered 1 kg of salty or bitter concentrates was compared with a sweet concentrate, with or without an artificial sweetener to mask adverse flavours. The cows were offered the test concentrates twice a day in a Latin-square design with seven feeding occasions per period and the apparent and actual (excluding non-feeding time) food intake rates were recorded for all seven feeding occasions. Both apparent and actual intake rates were slower for the bitter compared with the salty and sweet flavoured concentrate.For the first two feeding occasions the intake rate was recorded separately for the 1st min and the subsequent period until the end of feeding. The intake rate was faster in the 1st min because of more rapid prehension of the food and fewer interruptions to the feeding process. Where no mask was included there was no effect of flavour on the apparent intake rate in the 1st min of the first feeding occasion but in the 1st min of the second feeding occasion the apparent intake rate of the salty concentrate was less than that for the sweet or bitter concentrates. The actual intake rates of the bitter and salty concentrates were less than for the sweet concentrate. The mask increased the apparent intake rate of the bitter and sweet concentrates in the 1st min of both the first and second feeding occasions, by reducing the non-feeding time and it also increased the actual intake rate of salty concentrates.After the 1st min the apparent intake rate of the salty concentrate was faster than that of the bitter and sweet concentrates, where no mask was included. The mask increased the apparent intake rate of the sweet concentrates at this time but reduced it for salty and bitter concentrates. It therefore reduced the acclimatization to the salty and bitter concentrates and enhanced the attractiveness of the sweet concentrates.There was a residual effect from the previous period of concentrates which were eaten slowly i.e. salty concentrates, which reduced the 1st min intake of foods that were eaten rapidly, i.e. sweet concentrates, in the subsequent period. This was largely due to increases in the time spent pausing between bouts of food ingestion. After the 1st min the apparent intake rate of cows receiving salty concentrate for a second consecutive period was increased, suggesting acclimatization. The opposite effect was observed for the sweet concentrate, probably because the novelty of the sweetness had diminished, making it relatively less attractive to the cow. This experiment therefore provides evidence that bitter and to some extent salty concentrates are consumed at a slower rate than sweet concentrates, except for the 1st min in which they are offered to cattle and that a reduced concentrate intake rate may persist after the flavour is removed from the food. Cattle did, however, demonstrate an ability to acclimatize to salty concentrate over time.

Abstract Background The Regional Network for Asian Schistosomiasis and Other Helminth Zoonoses (RNAS+) was established in 1998, which has developed close partnerships with Asian countries endemic for schistosomiasis and other helminthiasis in Asia. RNAS+ has provided an ideal regional platform for policy-makers, practitioners and researchers on the prevention, control and research of parasitic diseases in Asian countries. China, one of the initiating countries, has provided significant technical and financial support to the regional network. However, its roles and contributions have not been explored so far. The purpose of this study was to assess China's contributions on the supporting of RNAS+ development. Methods An assessment research framework was developed to evaluate China’s contributions to RNAS+ in four aspects, including capacity building, funding support, coordination, and cooperation. An anonymous web-based questionnaire was designed to acquire respondents’ basic information, and information on China’s contributions, challenges and recommendations for RNAS+development. Each participant scored from 0 to 10 to assess China’s contribution: “0” represents no contribution, and “10” represents 100% contribution. Participants who included their e-mail address in the 2017–2019 RNAS+ annual workshops were invited to participate in the assessment. Results Of 71 participants enrolled, 41 responded to the survey. 37 (37/41, 90.24%) of them were from RNAS+ member countries, while the other 4 (4/41, 9.76%) were international observers. Most of the respondents (38/41, 92.68%) were familiar with RNAS+. Respondents reported that China’s contributions mainly focused on improving capacity building, providing funding support, coordination responsibility, and joint application of cooperation programs on RNAS+ development. The average scores of China’s contributions in the above four fields were 8.92, 8.64, 8.75, and 8.67, respectively, with an overall assessment score of 8.81 (10 for a maximum score). The challenge of RNAS+ included the lack of sustainable funding, skills, etc. and most participants expressed their continual need of China’s support. Conclusions This survey showed that China has played an important role in the development of RNAS+ since its establishment. This network-type organization for disease control and research can yet be regarded as a great potential pattern for China to enhance regional cooperation. These findings can be used to promote future cooperation between China and other RNAS+ member countries.
