Desulphurisation of dibenzothiophene and 4,6–dimethyl dibenzothiophene via enhanced hydrogenation reaction route using RePd–TiO2/SiO2 aerogel catalysts: kinetic parameters estimation and modelling
Authors: Prokic-Vidojevic Dragana , Glisic Sandra , Pesic Radojica , Orlovic Aleksandar
Published: July 2022

Re/Pd-TiO2/SiO2 aerogel catalysts were synthesized by using a sol-gel method
and supercritical drying in excess solvent and investigated in the reaction
of hydrodesulphurisation (HDS) of dibenzothiophene (DBT) and 4,6-dimethyl
dibenzothiophene (4,6-DMDBT). Both Re/Pd catalysts, obtained with and
without the use of mesitylene in the synthesis step, have shown increased
conversions of up to 70 % in the desulphurization of 4,6-DMDBT, when
compared to conventional Co/Mo hydroprocessing catalysts. This observation
is of importance for conversion of highly refractory 4,6-DMDBT and
hydroprocessing to produce ultra-low sulphur diesel fuels, ULSD. In order to
quantify the extent of desulphurisation, which proceeds via a hydrogenation
route, conversions of DBT and 4,6-DMDBT along with evolution of reaction
products characteristic for the direct desulphurisation route and the
hydrogenation route were monitored by using a gas chromatography?mass
spectrometry (GC-MS) analytical technique. The reaction was performed at 630
K and 6 MPa in a batch catalytic reactor. The experimental results were used
in the Hougen-Watson kinetic model describing DBT and 4,6-DMDBT
desulphurisation on ? and ? active sites. Kinetic parameters of this complex
catalytic kinetics were determined by using a Genetic Algorithm method and
minimum deviation function. Values of calculated kinetic parameters and
values of the ratio of 3-methylcyclohexyltoluene (MCHT and dimethyl biphenyl
(DMBPH) expressed as the MCHT/(MCHT+DMBPH) ratio ranging between 0.66 and
0.94, have confirmed that the hydrogenation route is the dominant route for
desulphurisation of 4,6-DMDBT.

Published: July 2022

Introduction. Patients with severe spasticity are effectively treated with intrathecal baclofen therapy (ITB), but because of their invalidity, in case of infection, prognosis is poor. Case outline. We present three cases (two men and one woman) of patients treated with baclofen intrathecal therapy due to spasticity of all four extremities who underwent SARS-CoV2 virus infection. Two of them have multiple sclerosis, and one has trauma of the cervical segment of the spinal cord. In all three patients, the clinical presentation of COVID-19 infection occurred within six months of implantation of the pump for ITB. They were successfully treated in hospital with same dose of the drug and without exacerbation of neurological status. Barthel index (BI) and modified Rankin score were same before and after COVID-19 infection. In two cases BI was 20, and in one 69; and modified Rankin score (mRS) was 3 in one case, and 5 in two cases. Conclusion. Patients with severe spasticity who require intrathecal baclofen therapy can be safely treated regardless of the pandemic.

Authors: ÜSTÜN Ayşe , ÖRTUCU Serkan
Published: July 2022

In this study, fluconazole (FLZ) loaded poly (lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) were prepared with two different formulations consisting of polyvinyl alcohol (PVA) and PVA-rhamnolipid (R) in order to improve antibiofilm activity against Candida albicans ATCC 90028. The encapsulation efficiency, drug loading capacity, in-vitro release, characterization and antibiofilm activity of these formulations were compared. Characterization of NPs were analyzed by scanning electron microscopy (SEM) and Zetasizer. Drug loading capacity and encapsulation efficiency percentages were measured by spectrophotometric method. PLGA-NPs were spherical in shape with mean sizes of ~300 nm and surface charge of FLZ loaded PVA and PVA-R-PLGA NPs -25,9±1.99, -48,1±2.46, respectively. Sustained release of FLZ (≥60% after 6 h) were obtained in PVA-R PLGA-NPs. The encapsulation efficiency percentages of PVA-FLZ-PLGA and PVA-R-FLZ-PLGA were 50% and 85%, respectively. Antibiofilm inhibition percentages are 55% and 63%, respectively. These results show that the PVA-R-FLZ-PLGA drug delivery system is a new therapeutic approach that can be used in infections caused by C. albicans.

Published: July 2022

The article analyzes and compares charging stations for electric vehicles and their components. The analysis of charging modes of electric vehicles showed that four internationally standardized modes are used, three of which use alternating current with single-phase and three-phase switching and only one – direct current. When charging on direct current, the fastest charging is provided. There are four standardized cases of connecting charging stations to electric vehicles. Three cases of cable connection can be used on alternating current, only the third case – on direct current, and the fourth case – when wirelessly charging an electric car. Analysis of the principles of use of charging stations showed that they classify portable, wall, and stationary stations. National standards introduce road signs for electric vehicles, and a European standard establishes harmonized identifiers for the power supply of electric vehicles. There are some standardized protocols for the interaction of the charging station and the control server, which are designed to optimize energy resources and energy production systems. A comparison of existing types of connectors for charging electric vehicles has shown that the standardized interface between the charging station and the electric vehicle remains one of the most acute problems. Recommendations on approaches to metrological support of charging stations are formulated. The issue of international and regional standardization of electricity meters of direct current for use in charging stations remains relevant. International standards are transformed into relevant European standards without changes. However, in some cases, it is necessary to develop a special European standard, in particular for meters of active electrical energy of the direct current.

Authors: Yudanti Anggita , Setiadi Wicipto
Published: July 2022

In the context of development, laws and regulations are also a means to support the realization of development goals. The focus of this research is what makes regulations in Indonesia still problematic and what actions must be taken so that the regulatory planning and the regional development planning can be carried out carefully so as to produce good legal products. The method used in this research is a normative approach. Primary data are collected from legislation while secondary data are from books, journals and legal articles. The data are then analyzed in a qualitative descriptive technique. The results found that legislative planning and development planning are not integrated so that they are not synchronized and harmonious because there is a separation of schemes; there is a tendency for excessive formation of Ministerial regulations; and the weakness of the planning institutions for the formation of Governmental and Presidential Regulations. Efforts to synchronize the planning system between the center and the regions are needed so that the regulations formed run systematically and sustainably.

Authors: Adityo Rayno Dwi
Published: July 2022

Handling social conflicts can involve elements of the community, one of which is the involvement of community leaders as part of peacemakers and their position is recognized in the law on handling social conflicts. However, the definition of community leaders is still not clear. This article aims to analyze the meaning of community leaders in the law for handling social conflicts in terms of the principle of legal certainty. This article is based on normative juridical research with a literature research scheme. The result shows that the formulation of the concept of understanding community leaders has not fulfilled the element of legal certainty. A clear definition of community leaders will help determine the extent to which the limits of their authority are protected by law. This study also offers additional materials for those who have the authority to be able to make efforts to improve.
Why Marriage Mattered? Marriage and Social Reproduction - the Case of Late Medieval Portuguese Aristocracy (1380-1530)
Authors: Aguiar Miguel
Published: July 2022

¿Cuál era la importancia del matrimonio para la aristocracia medieval? A través del ejemplo de la nobleza curial portuguesa bajomedieval, este artículo plantea conocer las formas en las que el matrimonio contribuyó a proporcionar la estabilidad de la aristocracia como un grupo minoritario, endogámico y dominante. La documentación conservada en archivos públicos y señoriales ha permitido crear un corpus documental, integrado por contratos matrimoniales, testamentos y particiones familiares, a partir del que analizar los aspectos materiales, las estrategias familiares y otras interacciones sociales vinculadas al matrimonio. El argumento principal es que el matrimonio es un mecanismo esencial para construir fuertes y sólidas relaciones sociales. Este estudio de caso demuestra un modelo de endogamia social, organizado por las relaciones estructuradas en torno a la corte real, entrelazadas con matrimonios por consanguinidad distante y por estrecha afinidad.

Se analizan las diferentes dinámicas sepulcrales del poder laico en relación a la elección de sepulturas en los monasterios y conventos de Castilla durante la Baja Edad Media. A través del análisis de cada uno de los grupos de poder –familia real, oficiales de la corte, nobleza y oligarquías urbanas– se constatan diferentes dinámicas que van desde la concentración a la dispersión y desde la continuidad con los antepasados, hasta la ruptura. En dichas dinámicas intervinieron cuestiones como el poder alcanzado por un miembro del linaje, los cambios devocionales, la dispersión de los dominios señoriales, nuevas fundaciones monásticas o, del lado contrario, la falta de cohesión de un linaje. Todos estos y otros aspectos estuvieron presentes a la hora de la elección de la sepultura en un monasterio por parte de los poderosos.

Authors: Sha Zhan
Published: July 2022

Thriving of the society in Zhengzhou city and development of its economy needs scientific and practical solutions of two main problems; natural water shortage and pollution. It is essential to assess the groundwater quality in order to confirm public safety in Zhengzhou and to reduce contamination in there. Fuzzy Synthetic evaluation was applied to delineate the extent of groundwater contamination in Zhengzhou. Assessment of shallow groundwater results concluded that the first three grades of Chinese water quality standards are 91%, whereas the fourth and fifth grades constitute 9% of it. For the deep water quality, the first two grades are 94% and 6%. It is deduced that part of the shallow groundwater quality is effectively contaminated. Contamination disappears going downward into the deep water. Cluster analysis show exactly same deduction. Fuzzy synthetic evaluation results (using Geographic Information System) were employed to assess the groundwater flow direction around the surveyed wells. It is concluded that infiltration of upstream industrial groundwater is probable into the deep confined groundwater

MEASUREMENT OF MAGNETIC FIELDS EMITTED FROM WELDING MACHINES
Authors: Kamil . J. Ali
Published: July 2022

The electric arc welding process makes use of the heat produced by the electric arc to fusion weld metallic pieces. An electric arc is formed when an electric current passes between two electrodes separated by a short distance from each other. The aim of this work is to determine the electromagnetic field strength emitted by different electrical welding machines at different ranges and identify the safe ranges in order to avoid its negative health effects on the welder body. The research has been performed in two parts, mathematical calculations and practical measurements using (EMF-827) field tester. Both measurements indicate that these exposure levels lie within permissible international standard limits , but in some very close to the torch the values of magnetic filed are above the standard permissible values, so there is no harm to human health if the exposure is for an intermittent and discontinuous periods

PREDICTION OF PHYSICAL & THERMODYNAMICAL PROPERTIES FOR BINARY SYSTEMS USING EQUATION OF STATE
Authors: Karima M. Putrus
Published: July 2022

A single equation of state (EOS) such as Soave – Redlich Kwong EOS can accurately describe both the liquid and vapour phase, therefore it is used for binary systems to predict some physical and thermodynamical properties. Two methods, which are Soave- Redlich Kwong and Generalized Compressibility Factor Correlation are compared and adopted for the cubic equation of state to calculate molar volume, density, viscosity, thermal conductivity, specific heat and compressibility factor.

 In this paper a computer program is developed requiring critical properties to perform these calculations. The results are compared with some available literature data, and we find that the computer programs are shown to be adequately reliable for this purpose, with deviation in some properties equal to (3.6%) as other predictive programs and procedures. Also from this comparison we notice that the Generalized Compressibility Factor Correlation method is better and more general than the Soave- Redlich Kwong
BEARING CAPACITY BASED ON SPT-COMPUTER INTERPOLATION
Authors: Zakaria Waad
Published: July 2022

Any structural design must be accompanied with sound analysis referring to the foundation design. The columns carrying the total load of the building may be in very high stress. The actual stress that exists in columns may reach in actual cases to half f'c or more. On the other hand, the maximum carrying stress of soil is very much small compared with that for reinforced concrete, the situation that necessitate the enlargement of column end to have "a footing". While the compressive strength of concrete is easy to measure, the bearing stress of soil is not. Methods of evaluating the soil bearing capacity are numerous and consist of field and laboratory. The SPT is one of these field methods. Scientists tried to relate the SPT-N value with the soil strength properties resulting in large number of tables, charts, and graphs. This research considers the most famous methods to evaluate the bearing capacity from the SPT. A BASIC computer program is written to aid in using these formulas. In going to this step all tables, curves, and graphs must be converted to numerical equations. This is done by using the usual FD technique of interpolation. The authors feel that this program must be used with caution since it is not a replacement of sound hand calculations associated with engineering judgment and experience. This is because the very SPT is used only as a guide and never as a replacement of laboratory testing program except for sands since it is very difficult to get undisturbed samples.
Nonlinear Analysis of Reinforced Concrete Beams Strengthened with Prestressed CFRP sheets Under Cyclic Load
Authors: Jinan L. Abbas
Published: July 2022

Analysis of reinforced concrete beams strengthened by prestressed CFRP sheets has been investigated in this paper. A three dimensional finite element analysis ANSYS computer program (version 9.0) was conducted to obtain the response of the strengthened beams. The eight –node brick elements(solid 65) are used for the idealization of concrete while the CFRP sheets are idealized by using three-dimensional layered elements (solid 46).The steel plates are idealized by using three dimensional solid elements (solid 45).Five beams are analyzed in study ,four with prestressed –CFRP sheets and one with non-prestressed- CFRP sheet. The effect of different level of prestress ,induced by prestressing the CFRP –sheets, on the cracking loads and  flexural stiffness of the strengthened beams are studied. It is found that the cracking load and the flexural stiffness are significantly increased as the level of prestress increased. The response of the strengthened beam under cyclic loads is also conducted in terms of deflection versus number of cycles which is related to the cyclic behaviour of the constituent materials used in the beam ( concrete , tension steel, and CFRP sheets).

The deformation of each these materials under cyclic loadings is presented in terms of measured strains as a percent of the number of cycles of fatigue. The results obtained from finite element analysis are compared with available   experimental results and the comparison gives good accuracy
RESOURCES SUAINABILITY PLANNING MODEL USING HIERARCHICAL APPROACH FOR CONSTRUCTION PROJECT
Authors: ABBAS M. ABD
Published: July 2022

Within the early stages of construction project planning, resources restrictions are often neglected. Usually this leads to cost and schedule overruns. Moreover, the adoption of resources restricted project planning may lead to a complex optimization problem. Thus engineers should focus on resources-based project planning for more schedule efficiency. Nevertheless, the integration with traditional methods as the PERT (program evaluation and review technique) or the CPM (critical path method), can improve schedule reliability significantly in project failures due to insufficient resource allocation. Potential applications of resource-restricted project scheduling for construction project planning are revealed with some suggestions on the integration of this approach into traditional planning methods are made. For overlapping both, traditional planning methods as well as resource-based planning models, knowledge transferred from production planning to project planning by applying a hierarchical approach. Analyses of multi planning problems in construction projects are undertaken and the roles of the generalized resource-restricted project scheduling model and selected extensions within construction project planning are discussed

MEASUREMENT OF MAGNETIC FIELDS EMITTED FROM WELDING MACHINES
Authors: Kamil . J. Ali
Published: July 2022

The electric arc welding process makes use of the heat produced by the electric arc to fusion weld metallic pieces. An electric arc is formed when an electric current passes between two electrodes separated by a short distance from each other. The aim of this work is to determine the electromagnetic field strength emitted by different electrical welding machines at different ranges and identify the safe ranges in order to avoid its negative health effects on the welder body. The research has been performed in two parts, mathematical calculations and practical measurements using (EMF-827) field tester. Both measurements indicate that these exposure levels lie within permissible international standard limits , but in some very close to the torch the values of magnetic filed are above the standard permissible values, so there is no harm to human health if the exposure is for an intermittent and discontinuous periods.
