Central extracorporeal membrane oxygenation as a bridge to recovery in patients with myocardial stunning after coronary artery bypass grafting
Authors: Fouly Mohamed Abdel
Published: May 2020

Background: The role of central extracorporeal membrane oxygenation (ECMO) post coronary artery bypass grafting (CABG) in older patients is debatable. The objectives of our study were to investigate the role of central veno-arterial (V-A) ECMO as a bridge to recovery in patients with myocardial stunning after CABG and its effect on mortality in this group of patients.

Methods: Seventy-five patients had central ECMO as a bridge to recovery  after CABG because of myocardial stunning; 45 of them (60%) had survived (group 1), and mortality occurred in 30 patients (40%) (group 2). Preoperative risk factors such as hypertension, stroke, and renal failure were comparable between groups. In non-survivors, left main disease was more common (19 (63.3%) vs. 13 (28.9%); p= 0.003) and SYNTAX score was higher (Median 33 (25th- 75th percentiles); 33 (29- 35) vs. 26 (25- 32); p< 0.001).

Results: Cross-clamp time was shorter in group 1 (58 minutes; (52-62) vs 115.5 minutes; (84- 161) in group 2; p< 0.001). Cardiopulmonary bypass time was shorter in group 1 compared to group 2 (83; (70-90) vs. 155.5; (60 -120) minutes; p< 0.001). ECMO duration was longer in group 2 (6 days; (6-7) vs. 3 days; (3-4); p<0.001). Stroke occurred in 10 patients (33.33%) in group 2 vs. 1 patient (2.22%) in groups 1; p< 0.001. Longer cross-clamp (OR: 1.61, 95% CI: 1.11- 2.31, p= 0.011) and bypass time (OR: 1.76; 95% CI: 1.57- 1.99; p= 0.048) predicted postoperative mortality.

Conclusion: Central ven-arterial extramembrane oxygenation can be used as a bridge to recovery in patients with stunned myocardium post coronary bypass grafting, especially in centers where heart transplantation and ventricular assist devices are not available.

Day by day the need for electrical power is increasing due to the continuous growth and development in the social and economical status of the society. By and large in conventional electrical power system network, power flows from generating stations through transmission and distribution system to the end user. The demand for electrical power at the distribution systems is also increasing continuously. In order to meet the increase in the demand for the electrical power, it is required to increase the existing capacities of the generation and transmission & distribution system that involves lot of money and is a time consuming process. The best solution for this problem of increase in load demand is perfectly met with electric power generating units of smaller capacity which are going to be installed locally in the distribution system and are termed as “Distributed Generators (DGs)”. DGs not only supplies electrical power that meets the increase in load demand but also reduces the losses, improves the voltage profile and reliability of the system. To get maximum of these benefits, DGs are to be installed at its best optimal locations and are to be operated at its optimal generating capacities. In this work an algorithm based on MBAT is proposed to find the optimal locations and sizes of the DG units by considering the minimization of multiple objective functions like minimization of real power loss, cost function and total voltage deviation. The proposed algorithm is tested on IEEE-33 radial distribution systems and results are presented.

In this study, analysis of the hull forms of traditional vessels in Kerala, viz., Snake boat, Uru and Houseboat have been studied. Ideal draft from wave cut analysis, estimation of drag forces, pressure and velocity contours on the surface of the hulls has been studied using a proposed 3-D model. The CFD package SHIPFLOW 5.1® has been used for the hydrodynamic analysis of ship/vessel in this work. The wave-elevation vectors (Kelvin wave pattern) at different Froude numbers and the different draft has been evaluated along the length of the vessel. The results show that that out of the total drag force experienced by a Snake boat at the ideal draft, 66.8% is attributed to the frictional drag and only 33.2% is wave-making resistance drag. These values change to 73.1% and 26.9% respectively for Uru and 23.7% and 76.3% for a Houseboat. With regards to the magnitude of resistance drag values, the total resistance experience by an Uru when compared to Snake boat and Houseboat are 30.16 and 1.17 times respectively. It has also been found that the presence of the skeg improves the hydrodynamic performance of the Houseboat considerably. The findings will be useful to design these boats considering its specific applications.

Pada Putusan Perkara Nomor: 398/P.dt.G/2013/PA.Pbr, dimana Majelis Hakim Pengadilan Agama kelas IA Kota Pekanbaru memutuskan dan mengabulkan gugatan Penggugat, yakni: hak asuh anak (Hadhanah) diserahkan kepada Penggugat. Kajian ini lebih menelaah kepada proses pelaksanaan ek-sekusi hak asuh anak yang dilakukan di lapangan atas putusan tersebut. Dalam kajian dini di ketahui bahwa pelaksanaan eksekusi hingga penyelesaian akhir telah dilaksanakan sudah sesuai dengan pertimbangan dan aturan hukum yang berlaku di Indonesia. Namun ketika proses eksekusi itu di lakukan di kediaman Tergugat, keempat orang anak yang telah diputuskan Hakim hak asuhnya jatuh kepada Ayahnya (Penggugat) mengadakan perlawanan karena tidak bersedia untuk di eksekusi, dan tetap memilih untuk ikut bersama ibunya (Tergugat). Sehingga penyelesaikan akhir dalam perkara tersebut pelaksanaan eksekusi hak asuh anak ditunda sampai setelah anak tersebut mumayyiz dan di serahkan pada anak untuk memilih ayah atau ibunya sebagai pemegang hak pemeliharaannya. Dari kajian ini, perlunya kejelasan norma hukum yang menjadi acuan pelaksanaan eksekusi hak asuh anak bagi Pengadilan Agama, agar tidak menimbulkan kontradiksi yang berkelanjutan.

Published: May 2020

Impaksi gigi merupakan kondisi gigi tidak dapat tumbuh ke rongga mulut, dan masuk ke lengkung rahang. Kista dentigerous adalah kista di sekitar mahkota gigi yang terbentuk pada gigi belum erupsi. Kista dentigerous pada gigi belum erupsi terbentuk apabila di dalam lapisan epitel email yang tereduksi menumpuk cairan. Kista ini dapat menumpuk di antara epitel dan mahkota gigi yang belum erupsi. Laporan kasus ini bertujuan untuk memperlihatkan perubahan dari lesi pre-kista yang tidak dilakukan perawatan menjadi kista dentigerous dalam jangka waktu dua tahun setelah pasien melakukan perawatan gigi rutin pertama. Kasus ini pada pasien perempuan, berumur 19 tahun dengan keluhan terdapat gigi yang tidak tumbuh pada rahang atas dan terasa berjejal. Pasien ingin dirapikan giginya untuk alasan estetika. Hasil pemeriksaan radiograf panoramik ditemukan perkembangan lesi secara tidak sengaja. Dari radiograf rutin panoramik, terlihat gigi impaksi dengan gambaran lesi prekista dentigerous pada bagian mahkotanya. Dua tahun setelah perawatan pembersihan karang gigi dilakukan radiograf oklusal, terlihat lesi tersebut membesar dan telah berubah menjadi kista dentigerous. Erupsi gigi yang terlambat atau adanya impaksi pada gigi dapat menyebabkan penumpukan cairan di dalam lapisan epitel email gigi. Kista dentigerous dapat terbentuk karena ada cairan yang menumpuk di antara epitel dan mahkota gigi. Pertumbuhan kista yang lambat dan tidak adanya gejala penyerta menyebabkan kista ini baru terdeteksi dari pemeriksaan radiograf rutin.

A Robust-Synchronization-Loop for Grid-Connected Distributed Generation Converters
Authors: Amin Mohammad
Published: May 2020

In this paper, a novel Robust-Synchronization-Loop

(RSL) is proposed to track the phase and frequency of the grid voltage. The method can be widely applied to the grid-connected converters in integration of distributed generations (DGs). The detailed analytical model and the parameter tuning based on a small-signal model of the RSL are presented. It is shown that the eigenvalues associated with the RSL remain always on the left half-plane, thus, it provides better stability property with the grid-connected DG converters. In order to show the effectiveness of the proposed RSL, simulation results are provided for different

scenarios of the grid condition such as voltage and frequency disturbance, unbalance grid condition and grid faults. The results show that the proposed method effectively tracks the phase and frequency of the grid voltage and maintains the good synchronism of the DG converters during these different small and large disturbances in the power system.

Modified Symbiotic Organisms Search for Plug-In
Hybrid Electric Vehicles through Renewable Micro-Grids
Authors: P. Dr. Karrupusamy
Published: May 2020

This paper uses a modern stochastic framework for studying the storage devices, PHEVs (plug-in hybrid electric vehicles), RESs (renewable energy sources) and such MGs (micro grids) for optimal management of energy while applying the popular Monte Carlo simulation technique for modelling the uncertainties of RESs and PHEVs. Prominent charging patterns namely uncontrolled, smart and controlled charging schemes are implemented for analysis of response in MGs for varied PHEV charging behaviours. Simultaneously, we also apply a powerful and robust Symbiotic Organisms Search (SOS) algorithm for analysing the uncertain parameter behaviours in natural stochastic form and the optimal MG operation. The interactions observed in natural organisms that depend on other organisms for survival are simulated by SOS. The total search ability in global and local searches is improved effectively using the modified SOS algorithm. Multiple MG test systems with varied scheduling time limits are used for examination of the proposed technique and its performance. In the presence as well as absence of PHEV charging effects, comparison of proposed technique and other algorithms are conducted with case studies under diverse conditions.

This study investigated the perception of science and technology undergraduate students on the relevancy of entrepreneurial Studies in south west Nigeria Universities. Two research questions and three null hypotheses were formulated and tested to guide the study at 0.05 Significance level. This study employed descriptive research design of a survey type and multistage sampling technique to get a sample of 400 science and technology related undergraduates in Federal and State Universities. A self-designed questionnaire titled; Relevance of Entrepreneurship Study Questionnaire (RESQ) was developed for data collection. Content and face validity of the instrument was determined by three experts while the reliability of the instrument was determined through test-retest method using Pearson’s Product Moment Correlation Analysis. The reliability coefficient of 0.83 was obtained. Mean, percentages and bar charts were used to analyse the research questions while ANOVA and t-test statistics were used to test the hypothesis. The result shows that majority of respondents perceived entrepreneurship study as relevant to their university education. Significant difference did not also exist in the perception of respondents based on course of study. There was also no significant difference in the perceptions of undergraduate students based on Level and University Status. Based on the findings, it was recommended that University authorities should intensify efforts in promoting entrepreneurship development by embarking on mass capacity building. Government should engage in strengthening universities-private sector collaboration with attention to science and technology related disciplines to facilitate entrepreneurship development in areas such as agriculture, medicine, engineering, solid minerals exploitation, fabrication of scientific equipment and production of reagent.
(De)Legitimizing Violence: Gendering the Arab Spring - A Comparative Analysis of Institutions in Egypt and Tunisia
Authors: ElMorally Reham
Published: May 2020

The Arab Spring (2011) was characterized by uprisings in various Arab countries that attempted to oust their respective regimes. The revolutions diffused from the movement in Tunisia to the rest of the Arab countries. The Arab Spring was followed by what is now commonly known as the Arab Winter, i.e. the resurgence of the authoritarian and oppressive regimes and array of radicalization. This research attempts to compare and contrast the uprisings in Egypt, which is considered a failed story, and Tunisia, which is considered a success story. The underlying question is: what are the institutional and social structures that exist in the respective countries that have amounted to their success/failure? The hypothesis is that Tunisia’s social and institutional configurations are more gender conscious than Egypt’s, leading to a stronger and more resilient superstructure that encapsulated the aggregate of the population instead of lobbying for the interests of the social hegemonic blocs. In other words, Tunisia’s society might be more aware of the bargaining power the historically marginalized women have in ousting the regime, as opposed to the Egyptian population. This awareness is reflected in the structure of political institutions, the power dynamics within those institutions, and affects the selection and orientation of decision-makers.
Is All Fair in Distancing Human Rights from Customary International Law Rule on State of Necessity?
Authors: Krasikov Dmitry V. , Lipkina Nadezhda N.
Published: May 2020

The international human rights law theory and practice traditionally follow the path of distancing human rights from the state of necessity under general international law. The existence of derogation clauses contained in major human rights treaties excludes the possibility for States parties to invoke the customary rule on necessity to excuse non-compliance with the obligations under such treaties (the narrow distancing approach). Presently, a broader distancing approach, covering human rights obligations outside the treaties’ derogation regimes, is evolving employing certain alternative grounds for departure from human rights obligations. The article argues that the way the broader distancing approach evolves raises doubts as to its conformity with its intrinsic rationale. To address this concern a due account should be taken of the pro homine reasoning for distancing human rights from the state of necessity. The present paper is a part of a larger project “Circumstances precluding wrongfulness of conduct: the analysis of functional role and applicability parameters in the framework of International Human Rights Law” supported by the Russian Foundation for Basic Research (RFBR Grant No. 18-011-00660).
Talent Management Based-Education: Indonesian Case

Published: May 2020

This study aims to determine the effect variables on the implementation of talent management of based education (TMBE). The paper is part of the results study in 3 (three) cities in DKI Jakarta, Banten, West Java Province, Republic of Indonesia with a sample of three senior high schools each taken by purposive technique, especially good criteria and have teacher guidance and counseling status. From each school 20 high school teachers were randomly drawn to answer the questionnaire distributed to them. The questionnaire was previously validated and reliable using the product moment test criteria from Pearson and Cronbach Alpha with the help of the SPSS program version 24.0. Data is processed and analyzed using the Structural Equation Modeling (SEM) approach using the Lisrel 8.70 program. The study resulted that the provincial government policy variables (PDS), school conditions (SC), teaching activities (LT), teacher guidance and counseling (GC) functions, and parent participation (PP) had a direct positive effect on the TMBE, Cultural Values (CV), and National Education (NE) variables. The indirect effect of PDS, SC, LT, GC, PP on TMBE is greater through CV and NE, then TMBE has a positive effect on Student Outcome (SO). It is recommended that TMBE implementation requires a holistic approach taking into account the variables and all the indicators studied. Ignoring one or more variables and trend indicators will influence the success or failure of talent-based education management and in turn will have an impact on student achievement (SO).
