The research aimed at the economic evaluation of marine aquaculture in the Triangle area in Damietta Governorate. The data was collected using a personal interview questionnaire during the months of September and October of the year 2020. This is for a regular random sample of 57 holders of marine fish farms in Damietta Governorate, representing about 5% of the total holders of marine fish farms. The descriptive and quantitative statistical analysis method has been used to estimate some averages, percentages and economic indicators that serve the research objectives. The research reached several results, the most important of which are: (1) The relative contribution of natural fisheries in Egypt and Damietta Governorate declined, as their contribution reached 22.74% and 15.14%, respectively. While the role of fish farming has been steadily growing, its contribution amounted to 77.26% and 84.86% of the total fish production in Egypt and Damietta Governorate, which amounted to 1599.69 thousand tons, 150.36 thousand tons as an average for the period (2010-2019), respectively. (2) The average value of the variable and fixed costs per acre in marine farms amounted to 208.70 thousand pounds, 23.70 thousand pounds, representing 89.80%, 10.20%, respectively, of the total costs, which amounted to 232.40 thousand pounds/feddan. (3) The average selling price of a ton of sea bream and sea bass was 100 thousand pounds, 70 thousand pounds for mullet, and the average production per acre of marine fish was 2.889 tons, while the total revenue from sold marine fish was 283.23 thousand pounds/feddan. (4) Marine aquaculture projects generate profit and an economic return. (5) The feasibility of investing in marine aquaculture activity was shown, as the average internal rate of return was estimated at 37%. (6) Investment efficiency indicators are more sensitive to changes in the farm selling price of marine fish than changes in the purchase price of feed and fingerlings, but the profitability of these projects remains economically feasible. (7) The critical value of the average selling price of bream and sea bass was estimated at 88.50 thousand pounds / ton, and mullet 61.95 thousand pounds / ton, while the critical value for the price of a ton of fodder was 25.40 thousand pounds, while the critical value of the mortality rate was 30%. (8) The problems of marine fish farming facing the respondents were of high relative importance and were represented in administrative and organizational problems, technical and operational problems, and economic and marketing problems. (9) The most important proposals of the respondents to overcome the problems of marine fish farming that they face are to provide and support the prices of feed, seed, and production requirements from the Authority - Establishing fish sales and marketing outlets near the areas of marine fish farms - Constantly cleansing the septic tanks and public drains and increasing the number of openings and septic tanks in the Triangle area and the road. Port Said International to constantly replenish the water - Establishing a fish hatchery that serves the marine fish farms area in Damietta to provide fry continuously and in a timely manner - Increasing the rental period for marine fish farms while working on ownership of lands for owners of marine fish farms.

The state is concerned with maintaining a clean environment and gives top priority to facing various environmental challenges resulting from the negative practices of citizens, production institutions and service bodies that pollute the environment, and represent risks to human health and depletion of natural resources. The problem of the study crystallizes in the inability to expand the establishment of forests trees on the land of the governorate despite the availability of all of the lands eligible for cultivation, as well as the surplus in the sewage water in that governorate. The study relied on two types of data, which are the published and unpublished secondary data issued to some authorities, such as the Ministry of Agriculture and Land Reclamation, and the primary data through the questionnaire formThe study concluded that the net revenue unit from the water unit for the woody trees represented in eucalyptus, kazorina, and pine, It amounted to about 34.18, 29.80, and 29.3 pounds for each unit of treated wastewater, while this net decreased for each of Kaya, Conocarpis, and Neem trees, reaching about 3.17, 7.3, 8.2 pounds for each unit of treated wastewater, as for the net revenue It reached about 44.33, 42.25, 38.92 pounds per unit of waterThe treated sewage for each of the casuarina, eucalyptus, and pine trees, while the revenues decreased for each of the neem, conocarpus and kayatrees, which amounted to about 17.94, 15.84, 11.59 pounds for each unit of treated wastewater, and the amount of water needed to produce a ton of wood from wooden trees was about 52.06, 34.95, 215.62, 113.63, 59.09, 78 m3 for each of the camphor, casorina, and kaya trees, Conocarpus, pine and neem, respectively [ABSTRACT FROM AUTHOR]

The review of the literature survey of transient stability constrained optimal power flow (TSCOPF) shows that only mechanical input power is used as a key parameter in the energy sensitivity approaches while generator's voltage changes are not considered. Using AC-OPF, this paper considers the effect of generator voltage changes in the calculation of energy sensitivity. To evaluate the transient stability, a new index from the family of corrected hybrid techniques is proposed and applied. It is shown that the change of the proposed index against the mentioned key parameters is linear. Thus, to reduce the computational burden of the approach, this linear property is considered to define the transient stability constraint. The proposed framework is implemented on the New England 39-bus test network. A comparison of the obtained results with those in the literature survey shows that using the proposed approach, the operation cost is decreased from 61799.68 ($/h) to 60927.86 ($/h) which achieves 1.41% saving in the fuel cost while securing the network against considered contingency.

Background and Objective: The purpose of this study was to use the HELP model to estimate the leachate generation rate and its pattern in a landfill located in the semi-arid region of Iran. Materials and Methods: The input data for the model were collected through fieldwork. To evaluate the accuracy of outputs, the actual amount of leachate production has been measured on-site for 10 months. In addition, sensitivity analysis was conducted to find out the most important parameters in leachate generation in the landfill. Results: The results showed that the model was able to estimate the rate of leachate generation with an accuracy of 75.5% and the correlation between the model's estimated values and actual values was 60%. In addition. the sensitivity analysis showed that the most important factors affecting the leachate generation in the landfill were waste moisture content and rainfall, respectively. Conclusion: The model showed satisfactory performance in the prediction of leachate generation in the arid area. The model showed that the moisture content of the waste significantly contributes to leachate generation in Karaj landfill and therefore, it is suggested to identify and implement procedures to reduce the moisture content of the waste at the source of generation.

Purpose: This study aims to propose a multi-objective model for determining reliable suppliers of one-shot systems. Design/methodology/approach: First, based on the evaluation indicators, the risk of each supplier is estimated. The subsets’ risks are also evaluated using the causal-effect matrix. Considering possible events for the one-shot case and analyzing a fault tree led the researchers to meet the best composition of equipment. Findings: The proposed model is capable of leading practitioners to allocate suppliers effectively when a one-shot case is considered. Research limitations/implications: The results of this study are referred to the current equipment of the focused one-shot system. Also, the results are limited to potential risks identified, evaluations related to comments, and the proposed model for the considered time interval. Practical implications: Based on the findings, applying the proposed approach can lead to an effective management tool for selecting suppliers with acceptable risk in one-shot systems. Social implication: A one-shot device is defined as a unit that can be used only once, hence the device cannot be used for testing more times. Each subset used in one-shot systems, regardless of how it supplies, has a specific risk level. Depending on what any subset provides, it also affects the factors influencing the overall system failure. Therefore, selecting appropriate suppliers is significant to ensure correct function of a system. Originality/value: The proposed model can be used as a fast and reliable method for determining appropriate suppliers for one-shot systems, whose results can be relied upon with a suitable approximation in respect of the sensitivity analysis. To the best of the authors’ knowledge, nobody else have addressed the problem in such a way. [ABSTRACT FROM AUTHOR]
