Authors: Primejdie Lucian George , Achim Andrei Valentin , Bucur Diana Maria , Dunca Georgiana , Georgescu Sanda-Carmen
Published: May 2021

The paper focuses on the numerical modelling of a rural Water Distribution System (WDS), supplied from a deep well, from which the water is pumped in a water tower (storage tank). Consumers are fed gravitationally from the water tower, with variable demand over 24 hours. Simulations were carried out in EPANET 2.2 using two methods: Demand Driven Analysis (DDA) with outflow issuing from emitters, and Pressure Driven Analysis (PDA). To minimize numerical instabilities, a particular attention was paid to the groundwater well (modelled both with variable, and constant hydrodynamic level), as well as to the connection of the water tower to WDS (where the connection was made either using 2 pipes, or a single pipe). By applying the DDA and PDA methods to the resulting 2×2 configurations of the hydraulic system, a total of 8 sets of simulations (solutions) were obtained and compared. The most advantageous pair of method and configuration is recommended to be considered when modelling a complex (e.g. urban size) WDS with groundwater supply and storage tanks.

Published: May 2021

The present study focuses on the operation of a drip irrigation system for greenhouses rose cultivation in Adunatii-Copaceni, Giurgiu County, Romania. The numerical modelling of the irrigation system was performed in EPANET 2.2, using the pressure driven demand model. The pumping schedule fits the real operation, where five greenhouses are irrigated successively each morning, directly through pumping from a groundwater source. Fertigation is applied for each greenhouse every 5 days, in the evening, through pumping from a storage tank. Despite the hydraulic assumptions adopted to model the groundwater well and dripper lines, the computed results match the values of the outflow rates measured for the dripper lines of the real drip irrigation system. Simulations are useful to investigate, at no cost, different scenarios attached to the operation of the studied drip irrigation system.

Published: May 2021

Currently the optimization of raw materials, energetic efficiency and the reduction of environmental impact are aspects of such importance at the time of choosing a product, process or system. The healthcare buildings are a kind of building composed by a whole group of systems, products and processes. This means a great margin for improvement in energy efficiency and environmental impact caused during the construction as well. The main goal of this project is to verify the viability of applying a case of study of Life Cycle Analysis (LCA) in a healthcare building. After the analysis of the results obtained in previous studies, a series of advantages and drawbacks have appeared as a result of applying this tool in healthcare buildings. The result has been beyond satisfactory, since clear conclusions have been obtained from an exhaustive analysis. Among the most important conclusions, it should be noted that the LCA technique is a great asset to evaluate environmental impacts. The application of LCA methodology helps to reduce the total environmental impact generated during the construction of a healthcare building, having a great impact on social benefit as well as an economic benefit. This last is usually associated to the reduction of waste and operative costs and in the energy savings. Also, it has been proposed some solutions to the main drawbacks. These can be the draw of a guide for the application of the LCA technique or the implementation of educational courses.

Published: May 2021

A possible strategy for reducing energy consumption and carbon dioxide emissions in order to protect the environment is the recovery of heat from wastewater. This study aims to achieve an improvement in the effectiveness of heat transfer by changing the flow parameters by using a double heat exchanger to recover the heat from greywater. The results, the thermal energy from wastewater can be recovered, the effectiveness ranged between (25 % — 45 %) with the discharge of (0.15-0.51m3/h) lower to higher, respectively. The cold water flow has a clear effect on the heat transfer efficiency, the decrease in cold water velocity led to the increase in heat transfer performance. This technique is simple to implement and inexpensive. It can be designed and built on the basement of the multi-storey building. The dual heat exchanger splits the flow into two-pipe, decreasing the flow rate velocity and thus, increasing the heat transfer efficiency.

Maps are known since antiquity, the oldest examples are from the 6th to 5th centuries BC. From the Babylonian world map, known as the Imago Mundi, maps evolved continuously. In the present day, maps allow us to visualize data in new and informative ways and to present it in an interactive manner. In recent years, web mapping technology has become a necessity for urban planning, and not only, by helping the population to take better and informed decisions. When communicating with decision-makers or only to take the best decision we need first to assess the answers to all the following questions “What and Why and When and How and Where and Who” and what better way to do this than by using Open Data? The governmental and administrative institutions have data in the form of historical maps, topographic maps, digital terrain models, statistical analysis, and other types of data. Our goal was to make these data available for the public in an easy and interactive way, by creating web maps, applications, and a website that gathers all these data.
Original masonry versus advanced masonry
Authors: Irimia C M , Sofronie R
Published: May 2021

The paper deals with a comparative analysis between original and advanced masonry. Both are of high practical interest in buildings and monuments. Particularly, in seismic areas, where they are submitted to the strong actions of earthquakes, the Latin principle Primum non-nocere should be applied. That principle was considered by the Venice Chart in 1964. Later it was resumed by ICOMOS-Iscarsah Recommendations in 2001. The paper presents first some historical data for each type of masonry. The original masonry has a long history when it was well checked by time. On the contrary, the history of advanced masonry is very short. Among the basic proprieties of the original masonry is the ductility of the lime mortar. Its mechanical strengths are lower than that of bricks. In these conditions, the original masonry exhibits the phenomenon of self-defending by adaptation. It is not the case of the advanced masonry which remains stiff. By physical modeling, the main proprieties of original and advanced masonry were proved. Then, by numerical modeling, the testing results were generalized and prepared for further use in design and research. From the comparative analysis results that each of the two types of masonry has specific fields of application.
Reinforcing original masonry with polymer grids
Authors: Irimia C M , Sofronie R
Published: May 2021

The paper deals with enhancing the strength of original masonry with polymer grids by preserving its basic physical properties of strength, stiffness, and potential energy. The behavior of the original masonry is carefully analyzed. The adopted solution for seismic protection of masonry was based on Landau’s Theory of dislocation. The basic idea of the patented method of reinforcing original masonry was related to the vertical joints of the original masonry. The suitable reinforcement for the original masonry should have high strength and long durability. The paper is suggesting some applications of reinforcing the original masonry. The tests on physical models confirm the practical value of the proposed method of reinforcing the original masonry. The numerical models extend the field of application regarding the polymer grids as suitable reinforcements.

Authors: Anastase A , Tarlea G M
Published: May 2021

Considering the current EU regulations, the GWP limit for comercial refrigeration systems is 150 starting with 1st of January 2022. This study uses a selection software for condensing units to evaluate the options available on the UE market which can fulfill the GWP limit. For this purpose a theoretical comparison between R404A (past), R449A (present) and R744 (future) condensing units with a cooling power of 10kW is made. The COP in the range of ambient temperature from 0°C to +40°C is the main criterion evaluation. Size and weight are also evaluated as secondary criteria. The results of COP evaluation are similar with conclusions from other studies and confirm that R449A unit has better COP than R744 and R404A. Also the size of the unit in case of R744 is three times bigger than R449A unit. The main conclusion is that even if R744 has low GWP and fulfill the legislation requirment it has not good efficiency. Further studies should be made in order to find a good solution for small cooling capacities.
Case studies for existing buildings with blind walls
Authors: Draghici Robert , Abdulfattah Abdulfattah Zainulabdeen K.
Published: May 2021

The blind walls, arranged between the neighboring buildings, are at the same time structural walls for the buildings from the typological groups analyzed in this paper. The foundations we can find in these are in 95% of cases continuous, surface foundations: stone or brick masonry; simple, unreinforced concrete (due to the knowledge from the respective historical moment) or reinforced concrete.

Depending on the type of floor and the materials used, there may be: flexible floors, which do not have a horizontal diaphragm behavior (rigid and resistant washer), specific to floors with unidirectional discharge or rigid and resistant floors, which have a horizontal diaphragm behavior (rigid and resistant washer), specific to monolithic floors in RC.;

Regardless of the type of floors that are discharged at the turbocharged walls, it is observed that, at most, there are discharges only on one side of the turbines, and not on both sides as on the structural walls inside the buildings.

These aspects must be taken into account even if, through the safety measures and methods, the turban walls end up passing from type 1 to type 2, with the unloading of the floors.

Authors: Ungureanu R D , Toma M G , Dicu M
Published: May 2021

Currently, worldwide, different technologies or different materials are used to increase the performance of the asphalt mix. Depending on climate and traffic conditions, each country has adopted specific solutions that improve the behaviour of asphalt pavement over time. Because each of these products has a particular effect, it is not possible to add a product to the mix to improve all of its technical features. The performance of asphalt pavement depends on the optimal selection of basic materials: natural aggregates, filler, bitumen, polymer and fiber. The aim of this paper is to investigate the relationship between the constituents of the asphalt mixture and its physico-mechanical properties. Characteristic properties of bitumen used in the mixtures were determined by conventional bitumen tests and rheological tests according to SHRP. After optimum bitumen content was determined, the influence of the polymer in the mixture was studied. SMA mixes were prepared with different penetration grades bitumen, from different sources and performance tests were conducted in order to evaluate the behaviour of the mixtures.

The building seismic performance assessment can be defined as a posterior phase of investigation in which a detailed analysis is executed in order to evaluation of seismic damages and quantify the sequences of the earthquake for a building, this approach could be probabilistic evaluation or deterministic one. The aim of this paper is to perform seismic damage evaluation for educational multi-storey reinforced Concrete Building in Al-Mustaqbal University College (MUC) in Al-Hilla City, Babylon governorate in the middle of Iraq by using FEMA P-58 methodology. A 3D mathematical modelling, pushover analysis by using SeismoStruct software. In addition, incremental dynamic analysis (IDA) and fragility curve according to FEMA P-58 are developed in order to obtain damage limits in term of performance levels of the case study building. Fragility curves are useful tools for showing the probability of structural damage due to earthquakes as a function of ground motion indices. IDA is performed for those simulated building using twelve ground motions with scaling peak ground acceleration increased every 0.1g until it achieved 1.5g to determine the drift capacity of the building in four performance levels, operational (OP), immediate occupancy (IO), life safety (LS) and near collapse (NC) as defined in FEMA P-58. Based on those capacities, fragility curves were developed in terms of peak ground acceleration (PGA) and elastic spectral displacement for drift levels with lognormal distribution assumption.

Bookworm, religious nationalists, and thinker: Bung Hatta’s personality from a graphological, geographical, and historical analysis
Authors: Fauzi W I , Yulianti I
Published: May 2021

The younger generation needs “examples” that will be used as role models in developing their personality. There are many ways that can be done to understand a person’s character. Personality can be analyzed with a historical approach and spatial analysis where the character has undergone a process of socialization and internalization. Besides, personality can be explored with a graphological approach. Graphology is the art of interpreting a person’s personality characteristics by looking at the type of handwriting and signature. The main problem of this article is “how do Bung Hatta’s analysis results compare using the graphological, geographic, and historical approaches? This article takes a historical approach, geography, and handwriting analysis [graphology] approach to describe Bung Hatta’s personality. The influence of West Sumatra, with its Minang culture shaped Hatta as a nationalist and religious figure. In Padang, young Hatta began to be an independent person. He learned to take care of himself, divided his time between school and organization. While in Padang, in addition to public schools, Hatta also studied the Quran from local scholars such as Haji Abdullah Ahmad and also Abdul Karim Amirullah. Graphological and historical analysis shows Bung Hatta more as a thinker, a conceiver who conveyed his thoughts through writing since he was a student in the Netherlands. The figure of Hatta is inseparable from books because he is indeed a “bookworm”. Hatta’s thoughts on the Indonesian economy had a far-future vision. He initiated a people-based economy. Hatta has broad insight and is also visionary. His integrity is morally and politically recognized by his friends and foes.
