Published: May 2019

Para el estudiante universitario, analizar en base a situaciones que se ejecutan día a día, o sobre aquellas que son determinantes a la hora de tomar alguna decisión, cada vez se vuelve tarea más difícil, en vista de que el ser humano por lo general actúa de manera predictiva, imponiendo su convicción innata y de frente a la praxis tradicional del docente, no pone en práctica su capacidad reflexiva, ya que esta requiere de más tiempo de lo pensado. Cuando surgió el problema se estableció como objetivo primordial, proponer un conjunto de lineamientos para la formación del pensamiento reflexivo en el área de la Física I. Se aplicó una metodología de tipo descriptiva, proyectiva, con diseño no experimental transaccional de campo. Las unidades son estudiantes (61) y docentes (2). Se utilizaron como instrumentos dos cuestionarios. Se validaron mediante la consulta a expertos y su confiabilidad fue de 0.88. El contenido de la investigación comprendió los aspectos más relevantes sobre el desarrollo del Pensamiento Reflexivo y su incidencia en el Aprendizaje en el Área de la física; por ello se consideró pertinente definir lineamientos que permitan el aprendizaje reflexivo para lograr un aprendizaje significativo de la física.

Investigation of fused deposition modeling processing parameters of 3D PLA specimens by an experimental design methodology
Authors: Çelebi Ahu 
Published: May 2019

Abstract
The main objective of this study is to analyze the tensile strength of PLA parts manufactured through fused filament fabrication (FFF) using a commercially available 3D printer. This study is primarily focused on the effects of the tensile strength of specimens subjected to the influence of four factors; layer thickness, fill density, raster orientation and sample structure type. A 2331 mixed-level factorial design approach was used, and the individual effects of the four main factors and their interactions determined. This experimental design had been implemented for two different infills: rectilinear and honeycomb. Specimens were printed at raster orientation angles of 30 °, 60 ° and 90 ° at a fill density of 50 % and 100 %. A layer thickness of 0.15 mm and 0.05 mm was chosen for printing the specimens. The samples were tested using a standard tensile testing machine with an extensometer to determine mechanical strength characteristics such as ultimate tensile strength, maximum force and maximum elongation. The data obtained was then analyzed using Minitab 13.20 software. The results showed that 30 ° raster orientation yields the highest mechanical properties at each individual layer when compared to 60 ° and 90 °. The fill density proves to be the most influential parameter on tensile strength, followed by the sample structure type. The results also found tensile strength to directly proporionate to layer thickness. By improving the material properties through the addition of layers as observed in the results, it will be possible to provide support for software developers, mechanical designers and engineers to reduce manufacturing time, material use and costs.
Uncertainty analysis of milling parameters using Monte Carlo simulation, the Taguchi optimization method and data-driven modeling

Published: May 2019

Abstract
Surface roughness plays an important role in the performance of finished structures. The surface quality obtained is enormously affected by cutting parameters. Therefore, the purpose of the present study is to examine the surface roughness value of aluminum 7075 workpiece material during milling operation by considering three steps: (1) the multi-nonlinear regression (MNLR) modeling basis of Taguchi design, (2) optimization based on signal to noise ratio (S/N), and (3) probabilistic uncertainty analysis depending on Monte Carlo technique as a result of depth of cut, cutting speed and feed rate. The depth of cut of 0.2 mm, cutting speed of 900 m × min−1, and feed rate of 0.1 mm × tooth−1 were determined as Taguchi-optimized conditions with a surface roughness of 0.964 μm. In order to justify the surface roughness predicted under optimized conditions in relation to the predicted Taguchi method, three repetitive verification experiments were performed and surface roughness of 0.964 μm ± 0.3 % was achieved. The best-fit MNLR method with an R2
pred (predicted regression coefficient) of 98.02 % is useful for calculating the success of estimating the outcome variable. Monte Carlo simulations were found to be quite effective for identifying the uncertainties in surface roughness that could not be captured by means of deterministic methods.
Strengthening of reinforced concrete buildings with soft story irregularity
Authors: Döndüren Mahmud Sami , Nakipoğlu Abdulhamit 
Published: May 2019

Abstract
Turkey is one of the most earthquake-prone countries in the world. The studies on the damaged buildings with reinforced concrete structural systems, especially done after the 1999 Gölcük earthquake and other earthquakes in the past, showed that the negative effects of the structural irregularities in the buildings come to light through the impact of earthquake load. They also revealed that the regularity of structural systems is one of the main principles in the design of earthquake resistant reinforced concrete structural systems. In this study, two-story single-span 1/3 scaled reinforced concrete test specimens having soft story irregularity (interstory stiffness irregularity) and insufficient earthquake resistance were tested by applying different strengthening methods. The purpose of strengthening applications is to eliminate the adverse effects of the soft story irregularity. Reversed-cyclic lateral load was applied on the test specimens to simulate the earthquake effect. While the upper stories in all the test specimens had infill walls, the lower stories had been strengthened using different types of steel bracings. The first frame was strengthened with K-type shaped (<>), the second one with straight V-type (V) and the third with turned sideways V-type (>) steel diagonal elements. As a reference to these three strengthened frames, the following two frames, which were taken from another study, were used; a frame with both stories having infill walls and a frame with infill walls on the upper story, which is empty on the lower story. As a result of the study, load and displacement histories, hysteresis and envelope curves and energy dissipation graphs of these three strengthened reinforced concrete frames were obtained. Furthermore, all the experimental results, obtained graphs and the data from the reference frames were compared and interpreted. The results show that the frame strengthened with K-type steel bracings is the best solution to reduce the effect of soft story irregularity.
In-Service Microstructural Modifications caused by Fatigue Phenomena leading to the Failure of a High-Voltage Cable

Published: May 2019

Abstract
This study analyses the causes leading to the failure of a high-voltage cable in regions close to it “mooring” at the end near to one of the high-voltage towers. The horizontal span of the cable between moorings was over 1040 m, with a difference in elevation between high-voltage towers of approximately 300 m. The conductor was made up of 30 aluminium strands with a 7 strands eutectoid steel core. The aluminium filaments were distributed in 2 layers, an outer layer with 18 filaments and an inner layer with 12. The steel filaments were distributed in a layer composed of 6 filaments surrounding a single central filament. All the filaments had a diameter of 2.6 mm. Cold drawn and twisted aluminium and the possible presence of recovery substructures in regions close to the fracture were analysed by means of optical microscopy. The steel was similarly studied, verifying its pearlitic nature and assessing the existence of softening phenomena due to recovery or recrystallization. The thicknesses of the zinc coating on the steel filaments were determined. The fracture faces of the aluminium and steel filaments were analysed by scanning electron microscopy and the fused remains resulting from possible arcs between the aluminium filaments were examined. In order to assess the deterioration of the filaments, tensile tests were performed on all the individual filament in regions adjacent to and at a certain distance from the fracture. The failure of the conductor had its origin in the outer aluminium filaments due to causes imputable to fatigue phenomena. The reduction in the cross-section of the conductor led to an increase in temperature, leading to the weakening of the remaining aluminium filaments and their subsequent failure, the electrical current being subsequently transferred to the steel core. The increase in electrical resistivity characteristic of steel led to a significant increase in temperature that drastically decreased the mechanical strength of the steel cables.

Published: May 2019

Background: Red cell distribution width (RDW) is a routine parameter in fully automated hematology auto analyzer, can give the idea of iron deficiency before haemoglobin and mean corpuscular volume in early iron deficiency or latent stage. Patient can be benefited by doing complete blood count including RDW for the diagnosis of early iron deficiency as a cheaper test than iron profile. This study was aimed to predict early iron deficiency by RDW, mean corpuscular volume and haemoglobin concentration in pregnant women.
Methods: In this study, 190 pregnant women were included from Gynae and Obstetric outdoor of Bangabandhu Sheikh Mujib Medical University from august 2008-2009. Complete blood count including haemoglobin percentage, mean corpuscular volume and RDW and iron profile were done. RDW was compared with haemoglobin concentration and mean corpuscular volume in various stages of iron deficiency.
Results: RDW was more significant than haemoglobin concentration in latent iron deficiency when haemoglobin level was normal (p<0.05). In mild and moderate iron deficiency anemia, RDW was increased progressively though haemoglobin level was reduced. RDW was more significant than mean corpuscular volume level in latent iron deficiency, mild and moderate iron deficiency anemia. The difference of mean corpuscular volume and RDW was statistically significant (p<0.05) in latent iron deficiency, mild iron deficiency anaemia and moderate iron deficiency anaemia (p value of 0.001, 0.001 and 0.011). In this study RDW had sensitivity 82.3% and specificity 97.4%. haemoglobin concentration and mean corpuscular volume had sensitivity 56.6% and 29.2 % and specificity 90.9% and 98.7 % respectively. Based on the receiver-operator characteristic (ROC) curves RDW had the best area (0.925) under curve compared to haemoglobin and mean corpuscular volume.
Conclusion: Latent iron deficiency without other existing disease like haemoglobinopathy, early folate / vit B12 deficiency could be predicted early by increased RDW when haemoglobin concentration and mean corpuscular volume were normal.

Published: May 2019

Background: Chikungunya is a rapidly spreading viral infection of global concern. Initial presentation of chikungunya infection is often indistinguishable from other viral infections. In Bangladesh, chikungunya is an emerging infection. In this report, we describe socio-demographic, clinical and laboratory characteristics of chikungunya in a selected group of Bangladeshi patients.
Methods: A multi-center descriptive study was done including adult patients with chikungunya virus infection from July 1, 2017 to October 31, 2017. Diagnosis of chikungunya virus infection was confirmed by reverse transcriptase polymerase chain reaction (RT-PCR) or immunoglobulin M (IgM) against chikungunya.
Results: Total patients were 107 including 61 (57%) males. Mean age of the study participants was 35.6 (range 19-84) years. Ninety three (86.9%) patients presented with fever and 14 (13.1%) patients (with history of recent fever) presented due to joint pain. Most (93, 86.9%) patients were managed as out-patient basis; while 14 (13.1%) patients required hospitalization. Common features were fever/history of fever, joint pain, rash and lymphadenopathy. Out of 93 patients who presented with fever, 79 (85%) had concomitant arthralgia/ arthritis, 70 (75.3%) had persistent joint symptoms beyond febrile illness requiring paracetamol, 63 (67.2%) patients had joint pain beyond 3 weeks (sub-acute phase) requiring paracetamol, non-steroidal antiinflammatory drugs or corticosteroids and 11 patients had passed 3 months since symptom onset (chronic phase) and only one (9%) had joint symptoms requiring hydroxychloroquine. There was no death.
Conclusion: Clinical manifestation of chikungunya virus infection was comparable with other viral infections but arthritis/arthralgia was an important differentiating point. As chikungunya is an emerging infection in Bangladesh, physicians should have a high index of suspicion and care should be taken to exclude other viral infections specially dengue.

Background: Diabetes mellitus is the most frequently encountered endocrine disorder in pregnancy and is associated with adverse outcomes if remain undiagnosed or untreated. This study was done to compare the maternal and perinatal outcome of pregestational diabetes mellitus (PGDM) with that of gestational diabetes (GDM).
Methods: This observational analytical study with group comparison was carried out in the Department of Obstetrics and Gynaecology, BIRDEM General Hospital, Dhaka from July 2015 to June 2016. This study was conducted on two groups of pregnant women: group A (PGDM) and group B (GDM). A total of 100 cases were selected and in each group 50 pregnant women were enrolled. Singleton pregnancy and age 18 to 45 years were included. Pregnancy with hypertension, heart disease, renal disease and other metabolic disorders were excluded.
Results: In this study mean gestational age of the study subjects were 35.72 ± 2.61 weeks and 36.58 ± 2.34 weeks in PGDM and GDM groups. History of GDM [34.0% vs 16.0%], intrauterine death (IUD) [14.0% vs 2.0%] and abortion [22.0% vas 6.0%] were significantly higher among PGDM patients than GDM patients. Regarding present pregnancy complications, polyhydramnios [32.0% vs 14.0%], preterm delivery [38.0% vs 20.0%], vulvovaginitis [28.0% vs 12.0%] and premature rupture of membrane (PROM) [24.0% vs 8.0%] were significantly higher in PGDM than GDM patients. Wound infection was significantly high in PGDM groups [35.7% vs 11.1%] among the patients delivered by lower uterine Cesarean section (LUCS). Regarding perinatal complications, hypoglycemia [22.0% vs 8.0%], birth asphyxia [24.0% vs 8.0%], RDS [24.0% vs 8.0%] were significantly higher among PGDM comparing GDM patients.
Conclusion: The maternal and perinatal outcomes of pregestational diabetes mellitus were less favorable than those of gestational diabetes mellitus.
