Authors: Nagy Amira Mohamed , El-Nadi Mohamed ElHosseiny , Nasr Nany Ali Hassan , Hussien Hossam Mostafa 
Published: November 2021

Abstract
The study aimed to create a compact pretreatment unit before the ultrafiltration modules. This unit targeted to improve the inlet water quality to meet the average values of the feed water quality required for the ultrafiltration plants according to the manufacturer. The used unit in this study was a pipe worked as a sedimentation unit with inclined plates to apply the plate settler technology. The suitability of using this unit was determined by using varied water sources with different Total Suspended Solids (TSS) concentrations and different retention times. The removal efficiencies for the low TSS water source reached 96.47 %, 82.94 %, 64.80 % & 30.59 % with retention time 30 minutes, 15 minutes, 5 minutes & 20 seconds respectively. For the medium TSS water source at the same retention times, the removal efficiencies reached 97.33 %, 92.87 %, 86.10 % & 63.89 %. For the high TSS water source, the removal efficiencies reached 98.64 %, 93.86 %, 87.51 % & 76.23 %. These results make the sedimentation unit able to work as an effective pretreatment unit for the ultrafiltration units for all water sources.
Estimation of Mechanical Properties and Mass Density of Al-Malwiya Masonry
Authors: Husain Muhammed Abbas 
Published: November 2021

Abstract
This paper presents the first estimation for the mechanical properties and the mass density of the masonry of Al-Malwiya heritage minaret. Many approaches are investigated in order to estimate the modulus of elasticity, shear modulus, Poisson’s ratio, and the mass density for this historic masonry. The mechanical properties are estimated by using empirical formulas and analytical equations, while the mass density is estimated after carrying out experimental tests for the extracted samples of the historic mortar. The estimated properties showed relatively low values compared with the newly constructed masonries, but they were interpreted as reasonable for such a historic construction.

Published: November 2021

Abstract
Noise became one of the main environmental indicators of the quality of urban life. The aim of this study was to develop a traffic noise model for an arterial road in Amman, the capital of Jordan, which was being subjected to a persistent increase in traffic and its related issues. The characteristics of the traffic and its relevant noise were analysed to develop a noise prediction model using an adaptive neuro-fuzzy inference system (ANFIS). A geographic information system (GIS) was then implemented to model the current noise along the arterial road. The results of ANFIS model showed that traffic delays and the percentage of heavy vehicles were the main causes of traffic noise generation within the urban area. However, the developed ANFIS model can simulate traffic noise with a relatively low root mean square error. Furthermore, this study will help to improve the perception about traffic noise and its development along arterial roads.

Published: November 2021

Abstract
The hollow structural elements occupy a great deal of researchers’ interest due to the possibility of losing their weights and maintaining or developing their resistances especially when increasing both compressive and tensile strength of modern materials. The flexural strength based on the forces balance and stain compatibility was derived. Nine beams of Ultra High Performance concrete (UHPC) and conventional reinforced steel bars were casted. Several parameters were taken which are the thickness of the concrete top flange, thickness of the concrete bottom flange, depth of the longitudinal hollow and the ratio of the longitudinal reinforcing steel. By comp aring the practical and theoretical results, the proposed flexural strength provided a safety factor of one-fifth against the experimental collected data. The ultimate flexural force developed up 260 % when increasing the reinforced steel area 4.6 times and 230 % comparing with the solid beam. Many aspect ratios were also mentioned that keep the strength in developing.
Mitigation Techniques for Interior Radon in Refurbishment Work in High Radiation Areas of Galicia: An Experimental Model to Test Building Solutions
Authors: Pol Ricardo , Rodríguez Raúl , Quindos Luis , Fuente Ismael 
Published: November 2021

Abstract
Radon is a naturally occurring radioactive gas, which tends to accumulate inside built structures. It is therefore necessary to include techniques to mitigate radon concentration during refurbishing work. The aim of this study is to assess the effectiveness of a number of mitigation techniques, under real conditions, to determine which is most suitable, in each case, for use in rebuilding solutions. The methodology consisted in performing four experimental tests on mitigation strategies recommended by the Código Técnico de la Edificación (Technical Building Code) (CTE-DB-HS6) and by the Government of the Autonomous Community of Galicia, (Xunta de Galicia, 2018). The concentration was measured with three different systems: radon in soil at 80 cm, passive detectors to confirm mean concentration, and continuous monitoring by devices calibrated at the LaRUC Laboratory of the University of Cantabria, in order to compare the results of the tests. The experiments were carried out in premises located in a high radiation area in Arteixo (La Coruña, Spain). Four experimental models were designed, corresponding to each of the building solutions under study, and tested over a period of 16 days in two repeated series of trials. The results obtained show that, of the different strategies tested, pressurising the living space achieves an efficient reduction of the radon concentration with a significant simplicity of construction. This solution, compatible with the minimal intervention and reversibility principles stablished in the charters of Venice, Krakovia and Nara, is shown to be especially useful when work is carried out on structures considered to be part of protected heritage.

Abstract
Indiscriminate waste disposal poses a severe environmental challenge globally. Recycling of industrial wastes for concrete production is currently the utmost effective way of managing wastes for a cleaner environment and sustainable products. This study investigates the strength characteristics of self-compacting concrete (SCC) containing induction furnace slag (IFS) as a supplementary cementitious material (SCM). The materials utilized include 42.5R Portland cement, induction furnace slag as an SCM ranging from 0 to 50 % by cement weight at 10 % interval, river sand, granite, water and superplasticizer. The fresh properties were tested for filling ability, passing ability and segregation resistance, the strength characteristics measured include compressive strength, splitting tensile strength, flexural strength and Schmidt/rebound number. The oxide compositions and microstructural analysis of SCC were investigated using x-ray fluorescence analyser (XRF) and scanning electron microscopy equipped with energy-dispersive x-ray spectroscopy (SEM-EDS), respectively. Empirical correlations were statistically analyzed using MS-Excel tool. The filling ability characteristic was determined via both the slump flow test and the T50cm slump flow time test. Moreover, the passing ability characteristic was determined using L-Box test. The segregation resistance characteristic was determined using V-funnel at T5minutes test. The results of the fresh properties showed a reduction in the slump flow with increasing IFS content. On the other hand, the T50cm slump flow increased with increasing IFS content. Furthermore, the L-Box decreased with higher IFS content. On the contrary, the V-funnel at T5minutes increased considerably with greater IFS content. The strength test results revealed that the strength properties increased to 20 % IFS, with a value of 66.79 N/mm2 compressive strength at 56 days, giving a rise of 12.61 % over the control. The SCC microstructural examinations revealed the amorphous and better interface structures with increasing IFS content in the mix. The empirical correlations revealed that linear relationships exist among the measured responses (fresh and strength properties). Ultimately, IFS could be utilized as a sustainable material in producing self-compacting concrete.

Abstract
The main aim of the article is demonstrating successful design of spread foundations of a commercial centre building, where geotechnical monitoring allows us to check design efficiency and calculate reliability in comparison with real vertical deformation of building. Introduction to the case study area and building structure and foundations was done in previously published first part of the article in which engineering geological conditions were described. There was also presented a comparison of calculated vertical settlement of selected footings with the real geodetic measurement provided during construction time till the period of two years’ operation time after completion of civil works. Geotechnical engineers do not have many opportunities to evaluate their designs, especially when everything passes successfully. Our presented case study is one of the examples, which could be evaluated from the point of view of reliability index of design adjusted with real geodetic measurement. Index of reliability of selected foundations was calculated by deterministic probability methods. In order to evaluate thousands of statistical data combinations, programing tool in Python language was developed for batch processing calculation of vertical displacement of foundation in Plaxis software. Discussion part of the article contains the actual state of reliability theory in structural standards in Europe.

Abstract
The majority of historical heritage structures of Makli, Thatta require rehabilitation. As the Tomb of Jam Nizam-al-Din Samoo is near the slope’s edge, the settlement increased due to slope degradation. This study aims to investigate the effect of structural elements such as secant pile and structural nails on the settlement of Tomb. From this study, it was observed that with the installation of secant piles on the slope, Tomb’s settlement can be reduced considerably; moreover, the anchors did not have an appreciable role in the settlement. The secant pile of 12 m sufficient to reduce settlement. This will be economical and easy approach as compare to the retaining wall. The Factor of safety (FOS) reduced from 1.36 to 1.10 with increase of slope from 45 to 35. The FOS of slope also increased with the installation of nails from east side of slope. The will reduce the chances of slope failure and consequently the tilting/collapse of Tomb.

O artigo versa sobre a hipótese de adoção do sistema Multiportas no âmbito da Advocacia pública para oferecer a informação sobre os métodos autocompositivos previamente a uma judicialização. A Ouvidoria é considerada a primeira porta e um espaço de triagem e filtro de conflituosidade para que a maquina estatal não seja movimentada por mera deficiência ou inexistência de comunição.
RESUMO:
A Ouvidoria da Advocacia Geral da União é tratada como canal de acesso à atuação consensual, o que a torna autônoma em relação ao servir consultivo e contencioso. Primeira porta idealizada na hipótese de um Sistema Multiportas adaptado à Advocacia Pública Federal, que tem a capacidade de aproximar Estado e Cidadão, de modo a solucionar conflitos sem interveniência do Judiciário. O tratamento da comunicação pela Ouvidoria tem o benefício de distinguir conflitos reais dos aparentes e de propiciar a movimentação da máquina administrativa, lidando com os conflitos de forma mais econômica e racional, evitando-se que se repita um grave problema constituído no âmbito do Judiciário: a judicialização desnecessária ou precipitada que, muitas vezes, está longe de pacificar as partes.

Authors: Vieira da Silva Filho Edson , Helena Vieira da Silva Marina 
Published: November 2021

A realização de revista, tanto pessoal quanto íntima, em funcionários, no ambiente laboral, é pratica recorrente adotada pelos empregadores, levando, em uma perspectiva garantista e a partir da ótica da proteção de Direitos Fundamentais, à necessidade de análise dos princípios constitucionais aplicáveis nas referidas situações, uma vez que tais práticas violam os direitos dos empregados em não serem submetidos a tais constrangimentos. A partir de uma metodologia de revisão bibliográfica e de estudo de casos, o presente trabalho possui como objetivo central a realização, de acordo com a legislação vigente, e com os princípios constitucionais aplicáveis aos casos que tratam da matéria, segundo as perspectivas de Souto Maior, uma análise crítica acerca da impossibilidade de o empregador proceder a revista íntima e pessoal no empregado. Será analisada, primeiramente, a construção da legislação trabalhista existente aceca do tema, para que, posteriormente, sejam analisados os impactos gerados pela constitucionalização do direito trabalhista, com o advento do constitucionalismo contemporâneo e do seu núcleo duro de Direitos Fundamentais, especificamente na prática da revista, bem como nos efeitos dos princípios garantidores dos direitos dos empregados frente ao empregador, para que, por fim, possa se atingir o objetivo da pesquisa, ou seja, através de uma análise principiológica e jurisprudencial, com base em julgados dos Tribunais Regionais do Trabalho dos Estados de Minas Gerais e São Paulo em acórdãos dos últimos 10 anos, questionar e analisar a fundamentação para alguns dos posicionamentos distintos que são adotados acerca do mesmo tema buscando apontar o caminho decisório constitucionalmente adequado.
