The research deals with the issue of slums, urban sprawl on agriculture land and its impact on the city of Baghdad. This topic needs close attention because it has become a problem facing the city of Baghdad through recruiting agricultural lands and converting them to residential homes in addition to the transgression on the state lands and building abuses. This research deals with the causes of slums, irregular urban sprawl and risks of excesses on land uses of land in Baghdad. In this research, we try to know the extent to which these problems have affected the city of Baghdad. The research methodology based on the descriptive methodology to clarify the factors affecting urban sprawl at the expense of agricultural land, using studies in government and service institutions and images from satellites to clarify the size of urban sprawl over periods after the 2003 war. Finally, a conclusion and future solutions were set to solve these problems.

Technical operation of lifting and transport equipment is one of the key problems of ports and terminals. The functions of technical operation include maintenance and repair of lifting and transport equipment. The imperfection of the maintenance and repair system leads to downtime of lifting and transport equipment, which affects the cost of loading and unloading operations. The main requirements for technical operation are to ensure the quality and speed of loading and unloading operations with minimal operating costs. One of the indicators for assessing the quality of technical operation is the coefficient of technical readiness, which shows that the probability that the lifting and transport equipment will be in a working state at any time, except for periods in which operation is not provided. These periods include the time when the lifting and transport equipment is being maintained and repaired. Technical operation strategy is selected based on the technical readiness coefficient.

The current research empirically examines the connections between several factors in healthcare management operations in order to improve the ability to model and anticipate outcomes. This research incorporates demographic trends, illness incidence, healthcare infrastructure, and socio-economic influences to address the intricate nature of healthcare administration, which encompasses patient care, resource allocation, staff management, and financial planning. The study used a multifactor econometric model to examine the correlation between the rate of newly diagnosed patients per 100,000 population and characteristics such as financial resources, healthcare infrastructure, and demographic trends. The model integrates data from the Republic of Uzbekistan, examining characteristics such as state budget allocations, the average doctor-toresident ratio, the number of hospital beds per 10,000 people, and the quantity of hospitals and outpatient clinics. The findings emphasize the inverse linkages and direct correlations between these characteristics and the frequency of newly diagnosed patients, providing insights into successful healthcare management practices. Forecasting models are utilized to anticipate the future count of newly diagnosed patients, serving as a foundation for strategic planning in healthcare operations. The paper closes by discussing the model’s implications for efficiently allocating resources and enhancing healthcare outcomes.

Aviation is one of the most significant growth drivers not only for the transportation infrastructure, but also for country’s economy as it contributes to both industrial and social progress of society. The paper focuses on Sheremetyevo International Airport, one of the largest Russian airports and analyzes it in terms of short-term and long-term perspectives. Using real statistical data, the article presents the models for forecasting essential performance indicators of airports, namely, passenger traffic and revenue. By comparing quality characteristics, most suitable models were selected and checked for adequacy. Forecasts of the probable changes in the values of the performance indicators were made under the assumption of maintaining the previously formed development trend.

Based on the children’s road traffic injuries analysis and field pedestrians’ behavior observations during the roadway crossing, in order to reduce accidents among pedestrians-children, to create safe approaches to educational institutions is proposed.

The article covers the results of research conducted on production of fabrics of various blended composition, such as local wool + cotton + polyester and cotton + cattail, in order to develop a new assortment of costume fabrics of various compositions. The production of such costume fabrics did not require the replacement of technological equipment, only the equipment was partially improved in order to settle the new assortment of production fabrics. The model for knitting costume fabrics of various compositions that gives positive results has been developed.

The refrigerant R22 has great damage to the ozone layer. R404A is currently the mainstream environmentally friendly refrigerant approved and recommended by most countries in the world, and has zero damage to the ozone layer. Based on this, the performance of heat exchangers of R22 and R404A with different inlet qualities with the circuit number were simulated and compared by EVAP-COND software. The results show that the capacity of the evaporator with R404A was greater than that with R22. Moreover, the difference in the capacity of the evaporator with R410A and R22 drops first, and then it rises. The flow path with the number of circuits 2 had the largest heat exchange rate. The heat exchange rates of R22 and R404A are 4.40kW and 4.50kW, respectively. The heat exchange amount of R404A was larger than that of R22, and the difference in heat exchange amount decreases first and then increases with the increase of branches, and the maximum difference was 4.41%. R404A can be used as a substitute for R22 and had a higher heat exchange rate. It is more environmentally friendly and saves energy.

With the continuous development of industrial technology, the safety and efficiency of thermal equipment work in related industries and industrial fields are facing many problems. First, with the improvement of integrated level, the size of electronic components is getting smaller and smaller, and the heat load per unit area is increasing, which makes the traditional heat dissipation method difficult to meet the requirements; second, with the increase of energy-saving pressure, the temperature difference of low-temperature waste heat recovery is reduced, and the traditional heat exchange equipment is difficult to meet the working requirements. The pulsating heat pipe has the characteristics of small volume and excellent heat transfer performance. In view of the heat transfer performance of the pulsating heat pipe, we designed the gas-liquid pulsating heat pipe heat exchanger and studied its heat transfer performance, which has been verified to be effective.
