Published: October 2020

A Evolução Biológica (EB) constitui um eixo integrador dos conhecimentos biológicos produzidos pelos demais campos da Biologia; contudo, pesquisas apontam para a dificuldade do seu ensino e um déficit na sua aprendizagem. A Teoria da Carga Cognitiva (TCC) pode orientar tanto a elaboração de melhores recursos didáticos, que efetivamente contribuam para o processo de ensino-aprendizagem, quanto a construção de instrumentos para avaliar pedagogicamente tais recursos. Desse modo, o objetivo dessa pesquisa foi avaliar o potencial pedagógico de Objetos de Aprendizagem (OA) relacionados à EB a partir de alguns efeitos da TCC. Os 14 OAs relacionados à EB foram retirados do Banco Internacional de Objetos Educacionais (BIOE) e avaliados a partir dos efeitos da atenção dividida, modalidade, redundância e elementos isolados.

Imaging pearls of the annular pancreas on antenatal scan and its diagnostic dilemma: A case report
Authors: Roul Pradeep Kumar , Kaushik Ashish , Gupta Manish Kumar , Sherwani Poonam
Published: October 2020

Background: Annular pancreas is an uncommon cause of duodenal obstruction and rarely causes complete duodenal obstruction. Due to its rarity of identification in the antenatal period and overlapping imaging features with other causes of duodenal obstruction; it is often misdiagnosed.
Case presentation: A 33-year-old primigravida came for routine antenatal ultrasonography at 28 weeks and 4 days of gestational age. On antenatal ultrasonography, dilated duodenum and stomach were seen giving a double bubble sign and a hyperechoic band surrounding the duodenum. Associated polyhydramnios was also present. Fetal MRI was also done. Postpartum ultrasonography demonstrated pancreatic tissue surrounding the duodenum. The upper gastrointestinal contrast study showed a non-passage of contrast beyond the second part of the duodenum. Due to symptoms of obstruction, the neonate was operated on, and the underlying cause was found to be the annular pancreas.
Conclusion: Diagnosis of duodenal obstruction due to the annular pancreas is very important in the antenatal period to plan for appropriate therapeutic interventions after birth. A double bubble sign is seen due to various etiologies however the presence of a hyperechoic band in the antenatal ultrasound may point to the diagnosis of the annular pancreas.

Türk ve Avrupa Mimarisinde İnsan Ölçeği (15-18.yy)
Authors: ŞAHİN Halise
Published: October 2020

Mimarlık, kısaca inşa bilimi ve yapı tasarım sanatıdır. Hayvanlar, yuvalarını mükemmel şekilde inşa etmek için genetik kodlarını kullanırken; insanlar zevkleri, ideolojileri, duyguları ve değerleri gibi sayısız seçimleri cisimlendirirler. Dini gereksinimler için ibadethaneler, barınmak için konutlar, yaşamdan ayrılanları için anıt mezarlar yapan mimarlar, yapıtlarına bilinçli olarak veya bilinçaltlarının tezahürü olarak simgeler yüklerler. Bu çalışmanın amacı 15-18. yy tarihsel aralığındaki Türk ve Avrupa mimarlığını insan ölçeği simgesi yönünden karşılaştırmaktır. Anıtsal ve sivil mimarideki farklılıkları insan ölçeği cihetinden ortaya koymak ve bu farklılıklara yol açmış olabilecek faktörleri irdelemektir. Avrupa’da Antik Yunan’ın insan ölçeğinde yapılmış, zarif ve saf formlardaki mimarlığı, Antik Roma’ya aktarıldığında Romalılar bu mimarlığa güç simgesini eklemişlerdir. Öte dünya odaklı Mısır mimarlığı karşısında, Roma mimarlığı dünyaya odaklanmıştır. Yapılarında betonu kullanmaya başlayan Roma mimarları mekânı şekillendirirken kubbeli ve büyük yapıları, ışık-gölge oyunları ile “ihtişamın mimarlığı” şeklinde yeni bir simge oluşturmuşlardır. Devam eden süreçte Avrupa mimarlığı, bazen kilisenin, bazen imparatorların bazen de aristokrasinin otorite gösterisi haline getirilmiştir. Artık mimarlık, insan için değil, güç için yapılmaya başlanmıştır. Aynı dönemde Osmanlı mimarlığı tam bir tevazuu yansıtmaktadır. Türk mimarlığı her dönemde pragmatisttir. Yüz yirmi senede tamamlanabilen San Pietro karşısında, yedi senede bitirilen Süleymaniye buna en iyi örnektir. Osmanlı mimari kültürü daha uzun inşa süreçlerine sabır göstermek istememektedir. İmparatorluğun en güzel mimari eserlerinin bulunduğu İstanbul’un doğusunda da, batısında da insan ölçeğini aşan yaklaşımlar çokça vardır. Ancak insanı aşan mimari kültürü barındıran bu iki coğrafyanın arasında sıkışan Osmanlı, hiçbir zaman bunun bir parçası olmayı tercih etmemiştir.

Published: October 2020

Incidence of stroke among young adults between the age brackets of 20 to 54 years of age has increased significantly; suggesting that stroke in the young is on the rise. In a community based retrospective study, the proportion of all strokes that occurred in young adults increased from 13% to 19% over one decade. Additionally, the incidence rate of stroke among blacks increased from 83 per 100,000 to 128 per 100,000, as compared to whites in whom, the incidence rate increased from 26 to 48 per 100,000. Therefore, aggressive risk factor control particularly among blacks is extraordinarily important. Furthermore, almost all the conventional stroke risk factors for incident stroke, proved to also be a risk factor for recurrent stroke, suggesting that equal vigilance for risk-factor prevention and control is appropriate for primary and secondary stroke prevention. This review tends to shed some light on the role of sickle cell anaemia in the pathophysiologic mechanism of stroke hoping that, the review would not only create more awareness on stroke management but would inform policy-makers on the urgency and mechanism required for cheap and affordable treatment of acute stroke among sickle cell anaemia patient, particularly in resource limited countries like Nigeria. It would also be a useful resource material for regional, national and international bodies that are involved in the management of patients with stroke.

Thermal Stability of Poly (vinyl chloride) Formulations Containing Iron Additives as a Replacement for Antimony Oxide
Authors: BA Howell , YG Daniel , FJ Butwin , ED Weil
Published: October 2020

Poly (vinyl chloride) [PVC] is a widely used commodity polymer with particular application for wire and cable coating, and for pipe and profile extrusion. For processing, PVC must be heavily plasticized. In addition, a number of other additives are usually introduced to promote thermal stability, to enhance processability and to inhibit flammability. Antimony oxide is often used in PVC formulations. However, the growing concern about the negative health and environmental impacts of antimony oxide has stimulated efforts to find suitable replacements. Iron compounds have been examined as suitable replacements for antimony oxide. PVC formulations containing 45 phr of Pevalen plasticizer, 50 phr of magnesium hydroxide and 2 or 10 phr of an iron additive were processed using a two-roll mill at 180°C. The thermal degradation and flammability of these materials have been evaluated utilizing thermogravimetry (TGA) and limiting oxygen index (LOI) measurements. All of the iron additives are effective in increasing LOI for combustion of the blends and in promoting char formation. The impact of the presence of all the iron additives is comparable and independent of the oxidation level of iron. Based on considerations of cost and availability, simple iron oxide may be the additive of choice. Keywords: PVC additives; Antimony oxide replacements; Combustibility of formulated PVC; Impact of additives on the thermal stability of PVC;

Direct simulation of fiber suspensions under smalland large amplitude oscillatory shear flow
Authors: Mezher Rabih
Published: October 2020

Experimentally, oscillatory shear flow is used to investigate polymeric viscoelastic properties. However, the knowledge of the microstructure’s orientation evolution (kinematics) with time is essential in order to predict those properties, and is difficult experimentally. Therefore it is often required to conduct numerical simulations to get insight on the kinematics evolution of fiber suspensions. The main aim of the current work is to use direct numerical simulations to investigate the time evolution of the orientation and kinematics of fiber suspensions under small and large amplitude oscillatory shear flow. Keywords: fiber suspensions; direct numerical simulation; oscillatory shear flow; fiber-fiber interactions;
Chemical Bonds in Metallic Alloys
Authors: Ustinovshikov Yuri
Published: October 2020

This review article represents a summary of completed, original work, embodying the results of extensive laboratory and theoretical investigations as well as new interpretations of existing problems in Materials Science. Using the examples of a number of binary Ni-base and Fe-base alloys, the TEM method has shown that the main reason for the precipitation of particles of a new phase is the chemical interactions that always exist between all atoms of an alloy, both in the solid and in the liquid state. It has been found experimentally that the sign of the chemical interaction energy in many alloys changes with a temperature change (the ‘orderingphase separation’ transition). It has been shown that the cause of the ‘ordering-phase separation’ transition is the electronic ‘ionic bond ↔ covalent bond’ transition. Such a transition takes place when delocalization of a couple of the valence electrons occurs on the A and B atoms simultaneously with the hybridization of a couple of the valence electrons on the B atoms. All these discoveries radically change the existing ideas about diffusion phase transformations in alloys.

Published: October 2020

Robot manipulators, given their promising features and capabilities, have found a variety of applications in many fields including construction, nuclear, car, manufacturing and surgical industries, among others, which has turned them to a large and diffuse industry. In construction, use of robots has automated many tasks and risky jobs, including multitask road construction and maintenance processes based on ergonomic and economic analyses, surface finishing, concreting, excavating and backfilling, to name but a few. Hence, manipulators have progressively replaced human labor to meet strict health regulations, productivity gains, and control goals. Movement of an effector tool into a proper location and orientation required for a work object is the main role of a manipulator. In this research dynamic modeling and control of a 2-DOF planar robotic manipulator is presented using a PID controller to obtain optimal position of final operator of the manipulator. Considering nonlinearity of the system under consideration, to optimize final position of the manipulator, parameters of PID controller were tuned using Tabu Search (TS) algorithm as one of meta-heuristic optimization techniques. Numerical results obtained from simulations in this study demonstrated robustness and efficiency of the selected approach for optimizing the final position of the manipulator, minimizing oscillations and fast convergence of the error function to zero, compared to that of uncontrolled state as well as controlled system by PID controller with empirically adjusted factors. Efficiency of the proposed method was verified for different angular positions of joints in the manipulator. Keywords:Lagrangian Modeling; Manipulator; MIMO PID Controller; Evolutionary Algorithms

Published: October 2020

Goal of this research is to produce a controlling voltage for Pulse Width Modulation (PWM) generator so that its Total Harmonic Distortion (THD) characteristic is reduced and Dynamic Voltage Restorer (DVR) compensates function of the system against error as well as turbulence in such a way that the end user has no trouble with supplied voltage. In this study, a DVR system has been utilized which is capable of counteracting adverse effects of changing voltage against sensitive loads. Continuous and stable supply of energy is the most important goal in serviceability of electrical networks. Turbulence in distribution networks causes disturbances in level and quality of the voltage. To eliminate destructive effects of these disturbances especially over sensitive users, one could use compensator devices. So, a PSO-Fuzzy controller has been employed to optimize SAG characteristics of voltage of the sensitive load. Simulation results obtained in this study, considering the complicated and nonlinear nature of DVR system, demonstrates efficiency of proposed PSO-Fuzzy controller in improving behavior of the dynamic voltage restorer introduced to the network for the purpose of eliminating destructive effects of imminent disturbances over sensitive users.

A Markovian-based methodology for the life-cycle cost analysis of bridge maintenance interventions under changing deterioration rates
Authors: D Fernando , S Walbridge , B Wan
Published: October 2020

Markovian transition probability matrices employing condition states are often used in bridge management systems to determine optimal intervention strategies. This approach assumes a constant deterioration matrix throughout the entire analysis period. In addition, decisions to carry out interventions are normally based on deterioration to predefined condition states, which are generally not linked to structural safety. However, in order to adequately model and evaluate certain intervention options, such as fiber-reinforced polymer (FRP) strengthening, it is necessary to model the impact of the intervention on the deterioration rate, as well as the safety of the structure. This paper presents a Markovian approach to model interventions that impact deteriorating rates. A model employing this approach is proposed, which also accounts for the safety of the structure. A simplified methodology to determine the optimal intervention strategy based on steady state probabilities is also presented. The proposed model and methodology are illustrated in a hypothetical bridge example, where one of the interventions is FRP strengthening of a concrete girder bridge.

Authors: Dawood Eethar Thanon
Published: October 2020

Superplasticizer is one of the most common types of chemical admixtures used in the mortar or concrete, especially that characterized high performance like Reactive powder concrete. Recently, the chemical admixture is considered as one of the main components of cement-based products due to it has a significant role to improve the physical and mechanical properties generally. Therefore, the experimental work of this research has been an attempt to study the influence of two types of superplasticizers with different dosages on the properties of reactive powder concrete. The workability, compressive strength, and saturated surface dry density of reactive powder concrete used two types of chemical admixture(superplasticizer) individual and in combination have been studied and compared together. The results indicated that the use of superplasticizer type ViscoCrete-5930 in individual or combination with superplasticizer type KUT PLAST PCE600 has a positive impact on the properties of reactive powder concrete especially its flowability and compressive strength.

Adjuvant Surgical Oophorectomy Plus Tamoxifen: New Efficacy and Secondary Effects Data
Authors: RL Richard
Published: October 2020

Recent publication of the 8-year update of the SOFT and TEXT trials indirectly calls attention to the leading role that surgical oophorectomy plus tamoxifen (SO+T) should now play in global breast cancer care. The here-reviewed breadth of its therapeutic effects, and its practicality, distinguish this treatment from GnRH plus tamoxifen treatment. Ovarian function suppression, whether by surgery or by GnRH treatment, in combination with tamoxifen, has been repeatedly-and now conclusively with the TEXT and SOFT results-- demonstrated to be more effective as adjuvant therapy than tamoxifen alone. The magnitude of this benefit should be greater absolutely in more commonly higher-risk cases seen in low- and middle-income countries. SO+T has additional benefits on rates of cardiovascular disease and lung and ovarian cancers, which significantly outweigh minor increases in endometrial cancers and thromboembolism. The bone loss toxicity profile of SO+T is unique and salutary: no loss of hip bone mineral density in the first two years and modest loss only in the first year in the lumbar spine. In contrast, multiple clinical issues compromise the efficacy in clinical practice, safety and practicality of GnRH + tamoxifen treatment, and long-term effects on cardiovascular events and rates of other cancers are unknown. In achieving potential population benefits, surgical oophorectomy plus tamoxifen is an optimal therapy---the surgery can be obtained by the majority of global patients with very low complication rates, tamoxifen is inexpensive, and the drop out from any hormonal treatment is reduced.
