SUMMARYImprovements in farming systems and food supply will come from: increased production efficiencies per unit land area or per unit input of key components such as water or fertilizer; from less negative impact on local and global environments, allowing sustainable biodiversity goals to be integrated with production performance; and from enhanced approaches to bringing global supply and demand in balance, allowing internationally agreed goals for biosphere stability to be shaped, managed and delivered. Each stage will deliver significant improvements to current farming approaches. Modern engineering methods and technology advances have enhanced productivity in all major industries, and farming is yet to make much progress by developing and adopting these technologies. Sensors, control and integrated management systems will be major features, delivering enhanced farming productivity per unit input and per person employed, complemented by decreased environmental impacts and lower losses in the food chain. New insights into modelling and interpreting systems' performance will provide key contributions to optimization and control under complex challenges.

Nowadays steelworks exists unmatched phenomenon of production rhythm between basic oxygen furnace and continuous caster, which need to saving ladle to ensure the caster casting, therefore the scientific-reasonable saving ladle control model of steel ladle could achieve energy saving significance. Based on the steel ladles of H steelworks as the research object, this article analyzes its operation process and time, matching model of basic oxygen furnace and caster. Through analyzing the relationship between the time of saving ladle and heats, the control model of saving ladle is constructed, which could calculate the reasonable time value of saving ladle, full ladle operation time and turnover cycle. Through applying Gantt chart to analysis and study the turnover rule of steel ladle, the turnover number control model of steel ladle is constructed. Satisfactory effects were obtained after applying the control model in production: saving number and turnover number were reduced, turnover ratio was increased, temperature drop was reduced.

Abstract The water distribution plan for the three major irrigation districts (Changma, Shuangta, and Huahai) in the Shule River Basin in the planned year was analyzed in this study in an effort to resolve the insufficient natural endowment of water resources and contradiction between supply and demand throughout the basin. Based on this plan, and under the condition of satisfying the scheduling constraints of cascade reservoirs, the minimum total water supply shortage in the watershed was taken as the main goal coupled with the cascade reservoir runoff optimization control coefficient. An optimized dispatch model of the reservoir group was established accordingly. The large system coordination decomposition algorithm was called to solve the model and obtain the water scheduling scheme of each reservoir. After the optimal regulation of runoff, the water demand of the three major irrigation areas of Changma, Shuangta, and Huahai in the planned year is greater than the available water resources of the Shule River and the Petroleum River. The total surface runoff water shortage is 66.01 million m3, which cannot be satisfied. Among the reservoirs, Shuangta has the highest water shortage quota of 43.503 million m3, followed by Chijinxia with a water deficit quota of 22.18 million m3, and finally by Changma with a minimum water shortage quota of 0.3277 million m3. The results of this work may provide technical support for water resource allocation and regulations, as well as for the efficient usage of the Shule River Basin.

In order to improve the working efficiency of hot blast stoves, reduce environmental pollution, reduce labor intensity and improve combustion efficiency, this paper uses ANSYS software to simulate the temperature field and flow field of the hot blast stove, and uses the PID controller to realize the automatic control of the hot blast stove. The model and working principle of the hot blast stove are briefly introduced. The operating parameters (blowing fan air flow, coal intake) of the hot blast stove are briefly studied. The results show that the amount of air flow of the blast furnace depends on the coal intake of the hot blast stove, which is generally per kilogram of coal. 8m3-10m3- air is required. When the coal intake is 120kg/h and the air volume of the blower is 1200m3/h, the hot blast stove can work stably with high efficiency. The results obtained are input into the database for later combustion. The work provides a theoretical basis.

This paper is a contribution to the growing literature on the role of projective identification in understanding couples' dynamics. Projective identification as a defence is well suited to couples, as intimate partners provide an ideal location to deposit unwanted parts of the self. This paper illustrates how projective identification functions differently depending on the psychological health of the couple. It elucidates how healthier couples use projective identification more as a form of communication, whereas disturbed couples are inclined to employ it to invade and control the other, as captured by Meltzer's concept of "intrusive identification". These different uses of projective identification affect couples' capacities to provide what Bion called "containment". In disturbed couples, partners serve as what Meltzer termed "claustrums" whereby projections are not contained, but imprisoned or entombed in the other. Applying the concept of claustrum helps illuminate common feelings these couples express, such as feeling suffocated, stifled, trapped, held hostage, or feeling as if the relationship is killing them. Finally, this paper presents treatment challenges in working with more disturbed couples.

The design and control of blast furnace (BF) ironmaking must be optimized in order to be competitive and sustainable, particularly under the more and more demanding and tough economic and environmental conditions. To achieve this, it is necessary to understand the complex multiphase flow, heat and mass transfer, and global performance of a BF. In this paper injection of alternative reducing agents via lances in the tubers of blast furnaces is discussed to reduce the consumption of metallurgical coke. Besides liquid hydrocarbons and pulverized coal the injection of recycled waste plastics is possible, offering the opportunity to chemically reuse waste material and also utilize the energy contained in such remnants.

Regional Regulation (Perda) which regulates public issues such as prostitution, alcoholic beverages, gambling, and the relationship between men and women turns out to be identified as a Regional Regulation with nuances of Islamic law. in Banyumas Regency there is a Regional Regulation which if used by the identification of Arfiansyah above, it can be referred to as a Regional Regulation with nuances of Islamic law. The regulation is: Banyumas District Regulation Number 15 of 2014 concerning Control, Supervision and Control of Circulation of Alcoholic Beverages and Regional Regulations of Banyumas Regency Number 16 of 2015 concerning Community Disease Management. This research has two formulations of the first problem related to the results of the content of the analysis on the Perda that are nuanced by Islamic law in Banyumas Regency. Both of the results of the analysis content on the Regional Regulations that are nuanced by Islamic law in Banyumas Regency are not contrary to Law-Invitation Number 12 of 2011? This research is a qualitative-descriptive study. The research method used is normative juridical. The main source of data is the Banyumas District Regulation Number 15 of 2014 concerning Control, Supervision and Control of Circulation of Alcoholic Beverages and Regional Regulations of Banyumas Regency Number 16 of 2015 concerning Community Disease Management. Interviews were also conducted with resource persons. Furthermore, the results of the analysis were carried out. Regional Regulation No. 15 of 2014 is actually a Regional Regulation that has a broad purpose of public interest, for the nation and state. So that the claim that Perda No 15 of 2014 as a Regional Regulation with nuances of Islamic law is not true. Regional Regulation No. 16 of 2015 is actually a Regional Regulation that has a broad purpose of public interest, for the nation and state. So that the claim that Perda No 16 of 2015 as a Regional Regulation with nuances of Islamic law is not true. Both of these Perda (Perda No 15 of 2014 and Perda No. 16 of 2015) are not in conflict with Law No. 12 of 2011 concerning the Establishment of Legislation. Both in terms of content, principles, goals, arrangements, administrative sanctions and criminal sanctions. Formally and procedurally the two Perda are in accordance with Law Number 12 of 2011
