Published: September 2019

Introduction: GDM is a metabolic disorder defined as its recognition first time in pregnancy. Women with GDM are at increased risk of morbidity and poor fetal outcome. Hence it is essential that early diagnosis and management of disease is carried out to avoid poor maternal and fetal outcome. Objectives: The study was conducted to find out the prevalence of GDM in KHUH following the International Association of Diabetes and Pregnancy Study Groups (IADPSG} Criteria. Following this strict criteria we analyzed the management and its effect on maternal and fetal outcome. Study Design: Retrospective cohort study. Setting: King Hamad University Hospital. Period: Feb 2015-Jan 2016. Inclusion: Patients diagnosed as GDM after 75gm OGTT. Exclusion Criteria: Known diabetic. Patients with unknown diabetic status. Materials and Methods: The study included 230 patients mostly between 24-28 weeks attending the antenatal clinic and some in late third trimester. This study included patient with GDM from - Feb 2015-Jan 2016. For the said year the total number of deliveries were 2747. These patients were given 75 gm OGTT test, by taking first fasting levels and then were given 75 gms of glucose drink and blood levels were taken at 1and 2hrs respectively. The fasting, 1hr and 2hr values were <5.1, 1 hr <10 and 2hrs <8.5. Patient with GDM were managed and followed till delivery to find out the maternal and fetal outcome. Results: The prevalence of GDM in this study was 8%. The C-section rate was 21.8%. The antenatal complications were 7.3% and major complication was hypertension. The postnatal complications were 5.6% and main complication was post-partum haemorrhage (PPH) due to lacerations. Macrosomia was found in 3.4% of cases. The preterm delivery rate was 2.6%. NICU admission was 25.7% and 58.3% of these were admitted for 24 hour observation only. Conclusion: GDM affects maternal and fetal outcome.

Published: September 2019

Objectives: To observe the role of optical coherence tomography in patients receiving anti-vascular endothelial growth factors for the treatment of diabetic retinopathy. Study Design: Observational descriptive study. Setting: The study was conducted at Department of Ophthalmology, Shahida Islam Teaching Hospital, Lodhran. Period: January 2018 to December 2018. Material & Methods: 177 eyes of 156 patients with diabetic retinopathy were analyzed with optical coherence tomography to quantify and explore changes in macula and inner retinal structures and to see different patterns of DME pre and post intra-vitreal anti-VEGF injections. All eyes had baseline OCT, received anti-VEGF intra-vitreal injection Avastin (Bevacizumab) 1.25mg/0.05ml. Follow up OCT imagining was done 6 weeks after last injection. Results: The patients had mean age of 58.36 ± 3.67 years with the mean diabetes duration of 9.30 ± 2.76 years. Before intra-vitreal injection, two different patterns of DME were recognized and analyzed i.e. diffuse thickening of macula (n=117, 66.10%) and cystoids macular edema (n=60, 33.90%). Base line OCT showed mean ± SD central foveal thickness 416 ± 54µm (n=177). On post intra-vitreal injection OCT, mean ± SD macular thickness was 212 ± 35 µm (n=177). Conclusion: OCT is latest non-invasive imaging modality that currently helps in quantifying and understanding the anatomy of DME and inner retinal damage due to diabetes mellitus. Although vascular leakage in DME is assessed qualitatively with Fluorescein angiography, actual macular thickness calculated with OCT is very helpful in yielding efficacy of treatment. This tool should always be used in monitoring the effect of therapies in future studies.

The search for an efficient and safe resin removal method after debonding has resulted in the introduction of a wide array of instruments and techniques. In the previously, safety of rotary instruments was limited to inspecting the surface under a scanning electron microscope that lacks a quantitative scale. In this study, comparative assessment of the enamel roughness was done quantitavely using surface profilometer. Objectives: To evaluate quantitatively the enamel surface roughness following debonding using three different resin removal methods (composite removing pliers, ultrasonic scaler and low speed Tungsten Carbide bur). Study Design: Prospective study. Setting: Orthodontic clinic of Ihsan Mumtaz Hospital Lahore and PCSIR (Lahore). Period: 6 months from June 2018 to December 2018. Material and Methods: Ninety, healthy extracted maxillary premolars were taken and subjected to profilometric analysis to register four roughness parameters. Brackets were bonded and all specimens were immersed in distilled water for one week. After debonding, teeth were randomly divided into three groups and subjected to different resin removal methods. A second roughness recording was taken and compared with roughness at baseline interval. Enamel surface roughness with three resin removal methods were also compared with one other. Data Analysis: SPSS Version 20.0 was used. Paired t test was applied within three groups separately to establish the comparison between the enamel surface roughnesses at baseline. One way ANOVA was used to establish the comparison of increase in enamel surface roughness among three study groups compared using different resin removal methods (slow speed tungsten carbide bur, ultrasonic scaler and composite removing pliers). Results: Slow speed tungsten carbide bur created the least increase in enamel surface roughness while ultra-sonic scaler had the most elevated values. Conclusion: Enamel surface roughness following debonding can be minimized with the use of tungsten carbide bur for resin removal in a slow speed hand piece.

PREDICTION OF HEAT TRANSFER CHARACTERISTICS FOR FORCED CONVECTION PIPE FLOW USING ARTIFICIAL NEURAL NETWORKS
Authors: Saleem Khalid , Kheioon Imad , Sultan Hussien
Published: September 2019

This paper investigates the ability of utilizing the artificial neural network (ANN) in calculating the forced convection characteristics coefficients from internal flow of air inside a pipe subjected to constant heat flux. The heat transfer characteristics such as Nusselt number (Nu), Stanton number (St) and friction factor (f) which are calculated using the empirical correlations have high deviation from that obtained from the experiments. So, the ANN method is proposed for predicting these characteristics coefficients more close to the experimental results. The training and testing data for optimizing the ANN structure are based on the experimental data obtained from the experiments performed on a forced convection apparatus. Three training algorithms for the training of the ANN were used and the presented ANN is implemented by using such MATLAB program. For the preferable ANN structure acquired in the current work, an acceptable mean square error was achieved for the training and test data, using the Trainlm algorithm. The results reveal that the estimated results are very close to the experimental data. Also, a new Graphical User Interface (GUI) is implemented for the application of ANN in the calculation of the attempted heat transfer parameters.

COMPARATIVE STUDY OF META-HEURISTIC AND CLASSICAL TECHNIQUES FOR AUTOMATIC GENERATION CONTROL OF A MULTI-SOURCE SINGLE-AREA HYDRO-THERMAL-GAS POWER SYSTEM
Authors: Dinakin Demilade , Oluseyi Peter
Published: September 2019

The PID controller still remains a widely used and very effective means of achieving stability in control systems. Generally, the performance of the controller is determined by the proportional, integral and derivative gains of the controller. The classical techniques: Ziegler-Nichols (ZN) open loop method; ZN closed loop method; Chien-Hrones-Reswick (C-H-R) load rejection method; and meta-heuristic technique: the fuzzy logic algorithm, are used to determine the tuning parameters of the PID controller in this study. The performance comparison of these controllers is done for automatic generation control (AGC) of a multi-source single-area hydro-thermal-gas power system. In such power systems, each source has a participation factor that determines its contribution to total power generation. The root mean square error (RMSE) is deployed to determine the proportionate balance of each generator’s output with its corresponding participation factor. The performance comparison of the controllers using Simulink/MATLAB shows that the fuzzy-PID controller achieved the most proportionate generation balance.

REFLECTIVE PRACTICE AND SELF-IDENTITY AS PARTS OF PROFESSIONAL DEVELOPMENT: A SURVEY IN A TERTIARY LEVEL
Authors: Amalia Lulu Laela
Published: September 2019

This study aims at revealing the knowledge of the teachers on the concept of reflective practice and self-identity as parts of professional development in an EFL higher education context. Reflective practice is closely related to the idea of learning from experience (Thomson & Pascal, 2012) and ithas been an important activity since 1980s in western education. Unfortunately, it has not been treated as one in Asian context, let alone in Indonesia. Despite the debate on the constant definition of reflective practice, investigating the understanding of the concept is yet thought-provoking. Thus, this study involves some teachers in tertiary level from both state and private universities in Indonesia. The data in this study are gained through distributing a Likert scale questionnaire on the knowledge of Reflective Practice and self-identity and an interview as a follow up data collection method in order to have thorough information. The result of the study shows that almost all teachers are aware of both concepts and their benefits for their professional development. Key words: Reflective practice, Professional development, Self-identity

Variación del color de flores y números cromosómicos en el noroeste del área de distribución de Turnera sidoides (Turneraceae)
Authors: Solís Neffa Viviana G. , Panseri Andrea F. , Reynoso Walter , Seijo J. Guillermo
Published: September 2019

En el marco de los estudios evolutivos que se desarrollan en el complejo autopoliploide Turnera sidoides (x= 7) se realizó un muestreo sistemático en el noroeste de su área de distribución. Se hallaron 6 poblaciones con flores de color salmón y 35 con flores amarillas de la subsp. pinnatifida. La distribución de estas poblaciones está asociada con variables climáticas y espaciales. Las poblaciones que presentan flores de color salmón viven en los bosques semiáridos (Provincia Biogeográfica del Chaco Boreal) y las de flores amarillas en los valles interandinos (Provincia Biogeográfica Boliviano-Tucumana). Todas las poblaciones analizadas son diploides. Los resultados obtenidos sustentan el modelo de diversificación alopátrica de las poblaciones con diferente color de flores a nivel diploide, probablemente favorecido por el sistema de barreras orográficas y los cambios climáticos surgidos a partir del levantamiento de los Andes y de las glaciaciones del Cuaternario. Además, el análisis evidencia que el noroeste del área de T. sidoides constituye un importante centro de variación de la subsp. pinnatifida y es el mayor centro de diploides hasta ahora detectado

Authors: Cabral Elsa L. , Mari Eliana , Pire Stella Maris
Published: September 2019

Se actualiza la taxonomía de la sección Pseudodiodia Hassl. del género BorreriaG. Mey., en la cual se incluían hasta ahora seis especies. En este trabajo se agregan cuatro especies a la sección, elevando el número a un total de diez taxones: dos de las Islas Galápagos (B. suberecta Hook. f. y B. dispersa Hook. f.) y dos continentales, de Brasil (B. decipiens K. Schum. y B. tocantinsiana E. L. Cabral & Bacigalupo). Se examinaron los granos de polen de esas especies mediante microscopio óptico y microscopio electrónico de barrido. Las especies continentales presentan el polen característico de Pseudodiodia (colpos largos y exina tectado-espinulosa), mientras que el polen producido por las especies insulares presenta variaciones en la exina.

Sterculiaceae de Paraguay. I. Ayenia, Byttneria, Guazuma, Helicteres, Melochia y Sterculia
Authors: Cristóbal Carmen L.
Published: September 2019

Se presenta la revisión de la familia Sterculiaceae para Paraguay, que está representada por 56 especies y 4 variedades, o sea un total de 59 entidades, de las cuales 3 son endémicas. Están repartidas en 7 géneros, los mismos que en la Argentina, con un número variable de especies, desde solamente una como enSterculia y Guazuma, hasta 16 como en Byttneria y Melochia.. La familia habita en todo el territorio en ambientes muy diversos, bosques en galería, campos de tierra fértil, también calcáreos, salitrosos o arenosos. El porte es generalmente arbustivo o subarbustivo, raro arbóreo o lianas. Las plantas son inermes o con aguijones como en especies de Byttneria. El proyecto de revisar esta familia incentivó la atención en los viajes de recolección. Como resultado se encontróAyenia magna representante de la sección Cybiostigma. La localidad más austral conocida era Trinidad en la costa de Venezuela, y ahora fue encontrada en Cerro León, en el centro-norte de Paraguay Occidental. Otro registro interesante es el deAyenia spinulosa de la cual se conocía solamente el ejemplar elegido como Tipo. Esta especie es propia de suelos calcáreos del Departamento Concepción. Una generosa cantidad de duplicados hizo posible que esta especie esté ahora representada en muchos herbarios del mundo. Las flores de las Sterculiaceae son siempre pequeñas, generalmente aglomeradas en las axilas de las hojas, a menudo son morfológicamente complejas. Los pétalos son rojizos o violáceos, raro amarillos como en Waltheria, o blancos. Las hojas son pecioladas, estipuladas, con pelos estrellados, también simples o glandulares. En Melochia pueden ser longistilas, brevistilas o medioestilas. El aspecto de las plantas y el indumento es bastante semejante al de muchas Malvaceae por esta razón es necesario revisar esta familia en los herbarios cuando se estudian las Sterculiaceae. Hay que prestar atención a las anteras que son 2-3-tecas y alargadas en las Sterculiaceae y monotecas y redondeadas en las Malvaceae. El texto incluye descripción, sinonimia, ilustración de cada taxón y claves para facilitar la identificación de cada uno de ellos, sus distribuciones están representadas en 11 mapas.Las ilustraciones de algunos géneros fueron tomadas de trabajos de Cristóbal, pero las de Melochia fueron elaboradas para el presente trabajo, lo que consideramos interesante, por que el autor de la monografía no incluye figuras de cada taxón.

Recursos fitoterapéuticos y comportamiento poblacional en la ribera rioplatense de Berisso, Buenos Aires, Argentina
Authors: Hernández Marcelo P. , Arambarri Ana M.
Published: September 2019

El trabajo da a conocer de manera comparativa, el recurso fitoterapéutico utilizado por los habitantes de dos sectores de la ribera rioplatense, uno continental, ubicado en las localidades de Palo Blanco y Los Talas denominado "Monte" y, otro insular, representado por la isla Paulino, ambos situados al noreste del partido de Berisso, provincia de Buenos Aires, Argentina. El objetivo es analizar comparativamente el comportamiento de los habitantes en el uso de las plantas medicinales en relación con el ambiente en que se encuentran situadas las unidades domésticas. Los resultados demostraron que existen diferencias atribuibles a factores tradicionales, estructurales y ambientales que conducen a un mayor conocimiento y uso de plantas para tratar afecciones de la piel, reumatismo, artritis y asma en la zona insular, mientras que en la zona continental, se destaca el uso de plantas para tratar parasitosis y problemas de las vías respiratorias. De un total de 61 especies, se destaca el uso de Aloe vera (L.) Burm f. (Asphodelaceae), Cortaderia selloana (Schult. & Schult. f.) Asch. & Graebn. (Poaceae) y Equisetum giganteum L. (Equisetaceae), así como el uso del liquen Ramalina celastri (Spreng.) Krog & Swinscow en la Isla Paulino.
