Published: June 2019

This article discusses and solves the problem of designing swimming pools.

Previously, before the advent of modern CAD, designers had to manually draw drawings, as any automation was not available, and it took too much time and effort, and the percentage of errors and errors was large enough.

With the advent of modern CAD, the design of objects has become much easier, it is enough to build a 3D model, and drawings and specifications will be formed automatically. And when you make any change to the 3D model, the drawings and specifications are updated automatically. This greatly simplifies and speeds up the design.

But not everything is still automated. When designing swimming pools, each new project begins with the selection of equipment for water treatment of a particular pool. Selection of equipment depends on the set of initial data determined by the customer, such as: the type and size of the pool, water exchange time, the desired temperature in the pool and so on. Based on these data, the equipment for the water treatment system is calculated (all calculations are strictly regulated according to GOST). Further, after the selection of equipment, a geometric 3D model of the pool is built. The geometric 3D model of the entire water treatment system is designed in stages: a pool bowl is designed, a technical room is designed, 3D models of previously calculated equipment are installed and everything is tied with a pipeline.

Since it takes a lot of time to calculate the equipment and design the pool bowl, and with each new project it has to be done "from scratch", it was decided to automate these modules. The article presents the development of a program to automate the calculation of equipment and the construction of a geometric 3D model of the pool bowl. This development is implemented in the company "ASTRAL CIS", engaged in the design of swimming pools and is actively used, reducing the design time by 2 working days.

A3D geological model was constructed for Al-Sadi reservoir/ Halfaya Oil Field which is discovered in 1976 and located 35 km from Amara city, southern of Iraq towards the Iraqi/ Iranian borders.

Petrel 2014 was used to build the geological model. This model was created depending on the available information about the reservoir under study such as 2D seismic map, top and bottom of wells, geological data & well log analysis (CPI). However, the reservoir was sub-divided into 132x117x80 grid cells in the X, Y&Z directions respectively, in order to well represent the entire Al-Sadi reservoir.

Well log interpretation (CPI) and core data for the existing 6 wells were the basis of the petrophysical model (Porosity, Water saturation, & Permeability) that were distributed for all the created grids and then upscaled.

Published: June 2019

Drastic threat to the natural system is caused by the uncontrolled release of synthetic pollutants, including azo dyes. This study centered on the decolorization and biodegradation of water soluble azo dye reactive blue (RB) in a batch mode sequential anaerobic-aerobic processes. A local sewage treatment plant was the source where activated sludge was collected to be used as non-adapted mixed culture with both free and the alginate immobilized cells for RB biodegradation. Under anaerobic conditions, the free and immobilized mixed cells were proved to completely decolorize 10 mg/ L of RB within 20 and 30 h, respectively. Alginate- immobilized mixed cells, resulted in 88%, 87%, and 87% maximum COD removals with samples containing RB at initial concentration of 10, 20, and 40 mg/L, respectively.  UV-vis spectra showed the biological cleavage of the azo bond in the anaerobic phase. Estimation of the phytotoxicity of the degraded metabolites suggested that the non-adapted immobilized mixed bacterial cells successfully detoxified RB azo dye.

Published: June 2019

Despite the history of Baghdad city extends into a long history, most of the contemporary buildings of Baghdad have been shaped in the era of modernity. Furthermore, most of the buildings of modernity in Baghdad are types of modernity buildings in Iraq as a whole, and due to all the joints of change and development are taking place in Iraq starts from Baghdad. Accordingly, all selected buildings, which would be presented as case studies of modernity will be exclusively in Baghdad. Although the importance of this significant modernist product, which represents the identity of Baghdad, which should be preserved by the renewal and preservation policies, the problem of research was emerged as follow: new finishing materials have been used to cover their exterior facades, which are unrelated to the notion of modernity.

The aim of this research is highlighting this Phenomena, which occurred after 2003 in Iraq, and characterized by changing the monuments of modernity buildings. This change was either by undergoing a lot of changes of their facades design or by covering them with new materials. Thus, the use of these materials, specifically plates of aluminum will be analyzed and then, discussed the effects implications, since these buildings represent a cultural and architectural heritage that establishes architectural successes. Consequently, the research methodology will depend on the choice of buildings that built in an important era (between 1950s and 1960s), analysis their facades before and after changes, in order to identify the reasons that resulted to the usage of such materials and suggest recommendations, which can address their negative impacts.

В статье рассматриваются психодидактические аспекты освоения студентами-гуманитариями содержания естественнонаучных дисциплин. Специфика обучения естественнонаучным дисциплинам студентов-гуманитариев определяется наличием у данной группы обучающихся особенностей восприятия и переработки информации. Для гуманитариев в большей мере характерно превалирование ассоциативного, образного мышления, эмоционального восприятия информации, отторжение формализованных, доказательных способов рассуждений, доминирование реального восприятия окружающего мира над абстрактным, идеализированным. Современные педагогические методики в основном ориентированы на левополушарное восприятие, именно поэтому правополушарные учащиеся оказываются в невыгодном положении. The article deals with psychodidactic aspects of mastering the content of natural sciences by humanities students. The specificity of teaching the natural science disciplines of humanities students is determined by the presence of features of perception and processing of information in this group of students. For the humanities, the prevalence of associative, figurative thinking, emotional perception of information, the rejection of formalized, evidence-based ways of reasoning, the dominance of the real perception of the world over the abstract, idealized, are more characteristic. Modern pedagogical methods are mainly focused on left hemisphere perception, which is why right hemispheric students find themselves at a disadvantage.

Authors: Vignoli Richele Grenge , Vechiato Fernando Luiz
Published: June 2019

Research data has been presented with a high level of research in the academic-scientific sphere in Europe, the USA and Brazil. However, sensitive data in this context are still little discussed in the scientific literature. The way in which they are presented, sensitive data are considered classified and highly confidential, with legal and ethical concerns about leakage, preservation, and safety. From this point of view, the research aimed to present initial discussions about sensitive data in research in the context of Information Science, in addition to demonstrating the secrecy, ethics and security care that researchers and information professionals need to have in order to deal with these types of data. The concern with the social issues that involve confidentiality of sensitive data of a subject when collecting scientific research data were also objects of discussion in this work. In order to reach the proposed objectives, a bibliographical research was carried out in the Capes Portal and mainly encompassed the Web of Science and LISA databases. As criteria for conceptual refinement, filters were used to insert the English, Spanish and Portuguese languages, with no pre-stipulated period for the consultation since it is a recent issue in Information Science and literature as a whole. The results of the research in which the keywords Data Research, Sensitive Data and Sensitive Research Data were used, did not cover sensitive data specifically in scientific research, demonstrating that the literature is more focused on discussions about privacy, ethical handling and ways through which such data can be preserved and secured by specific techniques. The research showed initial discussions about the concept of sensitive data from the point of view of Information Science and in scientific research. The awareness and commitment of the researchers and professionals of the area with the confidentiality, ethics and security of the data collected in research and which are sensitive, are fundamental points to be clarified in the management of these data. It should also be pointed out that the responsibility of the Sensitive Data of a research should involve the researcher and the manager (librarian) who will manipulate and organize the data so that they can be reused and / or shared without any legal and / or social damages involved in the process.

Published: June 2019

Los tumores del saco vitelino representan los tumores de células germinales testiculares malignos más frecuentes en la edad pediátrica. Dicha neoplasia, al igual que los otros subtipos de TCG, se han visto vinculados con factores de riesgo tales como criptorquidia, historia familiar de neoplasia testicular o TCG, alteraciones genéticas y microlitiasis testicular. La edad de presentación en la mayoría de los casos ronda los 16 y 17 meses de edad. En general, se presentan como masas testiculares asintomáticas, por lo que comúnmente los padres o los médicos de atención primaria son los primeros en identificarlas. Los tumores del seno endodérmico característicamente son productores de alfa feto proteína (AFP), por lo que este se considera el marcador serológico más importante, para el diagnóstico y el seguimiento posterior al tratamiento. El ultrasonido escrotal se considera la herramienta diagnóstica más importante para la caracterización de las masas testiculares. Se dice que por lo general los tumores del saco vitelino se presentan como masas sólidas, con gran hipervascularidad. La mayoría de los pacientes se presentan inicialmente con enfermedad estadío I, siendo la orquiectomía radical la única terapia requerida en esta fase. En casos más avanzados, la implementación de quimioterapia con platinos, ha demostrado mejorar la sobrevida.

Published: June 2019

La colestasis intrahepática del embarazo es la enfermedad hepática específica del embarazo más común, y se presenta típicamente durante el segundo trimestre tardío o tercer trimestre del embarazo. Tiene una etiología multifactorial, que dependerá de características genéticas e influencias hormonales entre otras variables. Se caracteriza por prurito y alteraciones a nivel de parámetros de laboratorio, tales como elevación de ácidos biliares y alteración de pruebas de función hepática. Aún es poco comprendida, y debido a que no se han estandarizado las guías, cuenta con distintos criterios diagnósticos. El pilar del tratamiento consiste en el ácido ursodesoxicólico. Suele ser benigna para la mujer con una rápida resolución posterior al parto, pero está asociada a complicaciones adversas perinatales, entre ellas el parto pretérmino y la muerte fetal intrauterina. Aún queda mucho por explorar y determinar respecto a esta patología de carácter complejo, para lograr alcanzar un consenso entre las distintas guías y conseguir las mejores recomendaciones para la población a escala mundial.

Los medicamentos son elementos que mejoran nuestra calidad de vida de diferentes maneras. Sin embargo, con el uso de los medicamentos podemos tener efectos secundarios relacionados con la interacción entre medicamento-medicamento, medicamentos-alimentos, medicamentos-suplementos, drogas-enfermedades, y por último medicamentos y el cuerpo humano. El síndrome de reacción eosinofílica medicamentosa y síntomas sistémicos es una toxicodermia grave, infrecuente y potencialmente mortal. La cronología abarca un intervalo de tiempo largo entre la toma del medicamento y la aparición de los primeros síntomas (2-8 semanas). Su fisiopatología no está totalmente dilucidada. Intervienen una respuesta inmunitaria contra el medicamento o sus metabolitos en un contexto de susceptibilidad genética (expresada por la asociación a algunos antígenos leucocíticos humanos [HLA] y/o anomalías del metabolismo del medicamento) y una reactivación de virus del grupo herpes (virus herpes humano 6 [VHH-6], VHH-7, virus de Epstein-Barr, citomegalovirus), con una respuesta inmunitaria linfocítica T dirigida contra estos virus. El diagnóstico de este síndrome se confirma con criterios diagnósticos clínicos y paraclínicos. El tratamiento no está bien estandarizado, pero se basa en la interrupción del presunto medicamento implicado y en una corticoterapia.

A RANS K-? SIMULATION OF 2D TURBULENT NATURAL CONVECTION IN AN ENCLOSURE WITH HEATING SOURCES
Authors: Ahmadi Mehdi , Agha Mirjalily Seyed Ali , Abbas Oloomi Seyed Amir
Published: June 2019

ABSTRACT: This study is conducted to investigate turbulent natural convection flow in an enclosure with thermal sources using the low-Reynolds number (LRN) k-? model. This enclosure has a cold source with temperature Tc and a hot source with temperature Th as thermal sources, other walls of the enclosure are adiabatic. The aim of this study is to predict the effect of change in Rayleigh number, repositioning of cold and hot sources, and thermal sources aspect ratio on the flow field, temperature, and rate of heat transfer. To achieve this aim, the equations of continuity, momentum, energy, turbulent kinetic energy, and kinetic energy dissipation are employed in the case of 2D turbulence with constant thermo-physical properties except the density in the buoyancy term (Boussinesq approximation). To numerically solve these equations, the finite volume method and SIMPLE algorithm are used. According to the modeling results, the most optimal temperature distribution in the enclosure is seen when the hot source is below the cold source. With decreasing distance between hot and cold sources, heat transfer rate increases. The maximal heat transfer rate is derived via study of the heating sources aspect ratio. In constant positions of cold and hot sources on a wall, the heat transfer rate increases with increasing Rayleigh number (Ra=109-1011).

ABSTAK: Kajian ini dijalankan bagi mengkaji perubahan semula jadi aliran perolakan dalam tempat tertutup dengan sumber haba menggunakan model k-? nombor Reynolds-rendah (LRN). Bekas tertutup ini mempunyai dua sumber haba iaitu sumber sejuk dengan suhu Tc dan sumber panas dengan suhu Th, manakala dinding lain bekas ini adalah adiabatik. Tujuan kajian ini adalah bagi mengesan perubahan nombor Rayleigh, mengubah sumber sejuk dan panas dan nisbah sumber haba kepada kawasan aliran, suhu dan halaju perubahan haba. Bagi mencapai tujuan tersebut, persamaan sambungan, momentum, tenaga, tenaga kinetik perolakan, dan pengurangan tenaga kinetik telah dilaksanakan dalam kes perolakan 2D dengan sifat fizikal-haba berterusan (malar) kecuali isipadu terma keapungan (anggaran Boussinesq). Bagi menyelesaikan persamaan ini secara berangka, kaedah isipadu terhad dan algorithma MUDAH telah digunakan. Berdasarkan keputusan model, suhu distribusi optimal dalam bekas tertutup dilihat apabila sumber panas adalah kurang daripada sumber sejuk. Dengan pengurangan jarak antara sumber panas dan sejuk, kadar pertukaran haba meningkat. Kadar pertukaran haba maksima telah diperoleh melalui kajian nisbah  aspek sumber pemanasan. Kadar pertukaran haba bertambah dengan bertambahnya nombor Rayleigh  (Ra=109-1011), pada posisi tetap sumber sejuk dan panas pada dinding bekas.

Published: June 2019

ABSTRACT: Piezoelectric energy harvesting is a possible breakthrough to reduce the global issue of electronic waste as they can efficiently convert the ambient vibration to the electrical energy without any additional power. This work presents the design and development of a piezoelectric energy harvester that is capable of transforming vibration from ambient sources into electricity. It focuses on a magnetically plucked piezoelectric beam as an alternative to the mechanically induced harvesters, as the latter are subjected to wear and tear. A prototype comprising of a 40 mm PZT-5H piezoelectric beam with a permanent magnet mounted at one end of the beam, as well as a series of permanent magnets of same types attached on an eccentric rotor was developed along with a National Instruments® data acquisition device. Mean output voltages of 2.98 V, 1.76 V and 0.34 V were recorded when the eccentric rotors were slowly rotated at 8.4 rad/s with increasing distances of 5 mm, 7.5 mm and 10 mm respectively, between the magnets on the rotor and the beam. These results have proven that voltage could also be generated by magnetically plucking the piezoelectric beam, and by reducing the distance between magnets, the amount of voltage generated will be higher. The outcome of this work signifies the possibility for implementation of energy harvesters that are capable of powering electronic devices from hybrid kinetic motion, with a reduced risk of equipment fatigue.

ABSTRAK: Penjanaan tenaga melalui piezoelektrik adalah satu penemuan terbesar dalam mengurangkan isu global pengurusan sisa elektronik. Ini kerana ia berupaya mengubah getaran persekitaran kepada tenaga elektrik tanpa sebarang tambahan tenaga. Kajian ini berkenaan reka bentuk dan pembangunan penjana tenaga piezoelektrik yang mampu mengubah getaran persekitaran kepada elektrik. Fokus kajian adalah pada penjanaan tenaga secara magnetik dari bilah piezoelektrik sebagai alternatif kepada penjanaan mekanikal, kerana penjanaan tenaga secara mekanikal berisiko tinggi kepada kerosakan alat dalam jangkamasa panjang. Prototaip piezoelektrik PZT-5H yang berukuran 40 mm ini telah dilengkapi magnet kekal pada hujung bilah, serta satu siri magnet kekal jenis sama turut dipasang pada pemutar eksentrik bersama peranti pengambilan data National Instruments®. Secara purata, sebanyak 2.98 V, 1.76 V dan 0.34 V voltan output telah direkodkan ketika pemutar eksentrik berputar perlahan pada 8.4 rad/s dengan jarak tambahan antara magnet pemutar dan bilah piezoelektrik bersamaan 5 mm, 7.5 mm dan 10 mm, masing-masing. Keputusan menunjukkan tenaga dapat dihasilkan dengan cara pemacuan piezoelektrik secara magnetik, dan tenaga yang terhasil akan bertambah dengan pengurangan jarak antara magnet. Hasil kerja menunjukkan tenaga dapat dihasilkan daripada gerakan kinetik hibrid, dengan risiko rendah pada kerosakan alat.

Grease products recommended by OEM for conventional 11kV switchgears are generally trusted. Some disadvantages might however exist among them or their supply could be insufficient and lead to use of non-OEM-recommended grease. This paper reports analysis methods to evaluate both types of grease that were recently used in the switchgears at local electrical distribution stations owned by Tenaga Nasional Berhad. Hardened, greenish and severely irritating greases probably caused by incompatible compounding, electrochemical reaction, and hazardous components, respectively, were among common problems faced by workers. Eight physical tests and four chemical tests were conducted on 10 grease samples using thermogravimetry, switchgear rig, gas chromatography and infrared spectroscopy besides other equipment and standard methods. Grease stability, oil bleeding, flammability of grease droplet and dropping point were among the characteristics determined in the analyses. The results reveal copper corrosion, chemical change, instable and inconsistent grease, and toxics in grease, which surprisingly included the OEM-recommended one.

ABSTRAK: Produk gris yang disyorkan oleh Pengeluar Peralatan Asal (OEM) bagi gear-suis konvensional 11 kV secara umumnya dipercayai ramai. Kemungkinan terdapat kekurangan pada produk-produk tersebut ataupun bekalan gris mereka yang tidak mencukupi telah mendorong kepada penggunaan gris yang tidak disyorkan oleh OEM. Kaedah analisis kajian ini melaporkan tentang kedua-dua jenis gris yang kebelakangan ini digunakan oleh Tenaga Nasional Berhad pada gear-suis di stesen pencawang elektrik. Gris mengeras, berlumut dan menjengkelkan mungkin disebabkan oleh sebatian bahan yang tidak sesuai, tindak balas elektrokimia dan komponen yang tidak selamat, masing-masing adalah antara masalah yang dihadapi oleh para pekerja. Lapan ujian fizikal dan empat ujian kimia telah dijalankan pada 10 sampel gris menggunakan termogravimetri, pemakai gear-suis, kromatografi gas dan spektroskopi inframerah selain alatan lain dan kaedah-kaedah piawai. Antara ciri-ciri yang dikaji dalam analisis ini adalah kestabilan gris, sifat lelehan minyak, sifat mudah terbakar titisan gris dan takat rendah gris. Hasil kajian mendapati gris ini menyebabkan tembaga terhakis, sifat kimia berubah, sifat gris yang tidak stabil dan mudah berubah, dan juga beracun memberi kejutan kerana pihak OEM tetap mengesyorkan gris jenis ini.
