Authors: Prawesthi Endang , Gusfourni Rosita , Marsigit Didik 
Published: December 2019

The labeled denture is important to identify people who have memory loss or identify ofÂ bodies in mass disasters, mainly due to the fires. Denture labeling made of tinfoil or paper laminated, but this form can easily be damaged if exposed to high temperatures. Cobalt Chromium (CoCr)Â Alloy metal is resistant to high temperatures which has melting point 1150Âº-1500ÂºC, so that possibility can be used as a tool in identification.Â Purpose: To determineÂ indentation resistanceÂ ofÂ CoCr alloy plates on heating with high temperatures and be expected the use of its can be alternatives as denture labeling for forensic identification. Methods:Â Experimental Laboratory with sample form of plates made of CoCr metalÂ cast and measuring 30X10X2 mm, withÂ depth of indentation is 1.5 mm. The plates were heated with temperatures 400Âº, 800Âº,1050ÂºC andÂ duration 5 and 15 minutes in the preheatingÂ furnace machine. 42 samples were divided into 3 groups (temperature of heating) and each group was divided into 2 groups again (duration of heating). Results: The size of depth and width of indentation (mm) ofÂ plate for all groups, there was no significant difference between before and after heating, except in groups heating to a temperature of 1050Â°C for 15 minutesÂ (P<0.05). Conclusions: Heating with high temperature is not enough to make the plate damaged and deformed, so labeling indentationÂ can still be read clearly. The use of CoCrÂ plate can be alternatives as denture labeling.

Published: December 2019

Replication of observation allows consistent estimation of slope parameter of a linear structural model when the ratio of variances is unknown or when some external information about parameters is not available. In this paper, we look at the way a linear structural relationship model work by replicating observations with two different estimation methods of slope parameter and different cases of existence of outliers. The maximum likelihood estimate (MLE) and a new nonparametric robust estimation method Â are used to estimate the slope parameter in replicated linear structural relationship model (RLSRM). The simulation studies and the application of real data are used to investigate the performance of the estimated parameters.Â

Published: December 2019

The particle motion, temperature behavior, and drying rate of particle inside a vibrated fluidized bed dryer were numerically investigated in this work. In the simulation, the Distinct Element Method (DEM) based on the Newtonâ€™s second law of motion was used to solve the particle motion. The physical aspects of fluid motion and heat transfer were obtained by applying Computational Fluid Dynamics (CFD) technique. For the drying of particle, only the constant rate period was considered in order to save the computational time. Programming was developed in Standard-C language and using MATLAB to visualize the results. In the simulation, 2,000 particles with stiffness 800Â N m-1 were simulated in a rectangular bed. The developed model was validated with an experimental result of Gupta et al. [1]. The program was then used to study the effect of superficial gas velocity (U0), frequency of vibration (f) and amplitude of vibration (a) in fluidized bed dryer. At low velocities and no vibration of bed,Â articles in the bed were not fluidized but smoothly circulated. Thus, the heat transfer occurred only near the orifice. When superficial gas velocity increased, the fluidization of the particles was observed. The fluidization and drying rate improved with increased in superficial velocity for both vibrated fluidized bed and stationary bed. With introducing of vibration, the fluidization behavior of the particle was improved. The particles in the bed were well mixed and also increased the drying rate. From the simulation results, increasing of frequency and amplitude could not significantly improve rate of drying.

Published: December 2019

HIV or Human Immunodeficiency Virus is a virus affecting immune system consisting of white blood cells and lymphocytes called â€œT-4 cellâ€ or â€œCD-4 cellâ€ which fights infection. The fetus may easily contract the disease from mother with HIV and inflamed placenta. The study aimed to identify knowledge on mother-to-child transmission of HIV in pregnant women with HIV. The study design was quantitative with descriptive phenomenology approach and analysis by Colaizzi method. The study involved 9 participants. This study identified 7 themes including: 1) knowledge about HIV, 2) treatment of pregnant mothers with HIV during, 3) sources that support prevention of HIV, 4) information sources, 5) barrier in prevention, 6) how to deal with barrier, and 7) impact of HIV on fetus. Participants demonstrated inadequate level of knowledge about HIV transmission to fetus based on the identified themes. These findings may be beneficial for further studies and in development of health service programs for pregnant women, especially pregnant women with HIV. Â Â

Published: December 2019

The distribution of Formation Temperature of the Fika Shale Formation within part of Borno basin from five wireline logs was investigated.Â The area under studied covered about 20 by 40 kilometre square of the total land mass of the basin. The Fika shale sequence were identified at 865m to 1795m in Kinasar well, 640m to 1990m in Krumta, 980m to 1620m in Masu, 700m to 2710m in Tuma, 710m to 2220m in Wadi. The plot of the entire Formation Temperature of the study area reveals remarkable steep variations in temperature with increased range from 680C to 1280C starting from the southern eastern region to the north western region. This is possibly due to substantial temperature enhancing effects of the underlying basement complex. Interestingly, it was also observed that the minimal temperature variation occurred approximately 20C/ meter across the field and this also lays credence to the fact that the notable subsurface geothermal variation may be recent events initiated by the near- surface magmatic intrusive events which may have had adverse effects on the overlying sedimentary cover. Furthermore, it was deduced that the probability of hydrocarbon accumulation is better in the south eastern region than the north western region although the steep temperature variation of 20C/ meter within some part of the study area may perhaps reduce this possibility.

Neonatal sepsis is a major issue on neonatal-care field. This incident occurs by many factors, one of the factor is infant with a low birth weight. Blood culture is used as the gold standard for diagnosis. The spectrum of bacteria which caused neonatal sepsis is constantly change and vary due to antibiotic resistance phenomenon. This study aimed to determine the relationship of birth weight infant with bacteriological profile and antibiotic resistance of neonatal sepsis in RSAB Harapan Kita Jakarta. This study used observational method with cross sectional design and purposive sampling method which is analyzed by chisquare test. Medical record data and blood culture and antibiotic resistance test from all subjects in Januari until December 2018 were reviewed. The sample in this research is neonatal sepsis patients who met inclusion criteria were 51 patients. From 51 (55,43%) subjects, there were 39 (76,47%) neonatal sepsis in low birth weight infant. Klebsiella pneumonia spp (41,17%) and Staphylococcus epidermidis (19,60%) were the predominant pathogens. Amikacin (62,74%), and meropenem (50,98%) were the most susceptible antibiotic towards bacteria. Maximum resistance among organisms was seen in cefotaxime (84,31%), ceftazidime (78,43%), and amoxicillin (70,58%).Â The result of the analysis found there is a relationship between birth weight infant and bacteriological profile (p-value = 0,035), but there is no relationship between birth weight infant and antibiotic resistance of neonatal sepsis (p-value =0,092; 0,066; and 0,521). There is a relationship between birth weight infant and bacteriological profile , but there is no relationship between birth weight infant and antibiotic resistance of neonatal sepsis.
Emission Trading Scheme and the Effect of Carbon Fee on Petroleum Refineries
Authors: Orugba Henry O. , Ogbeide Samuel E , Osagie Christian 
Published: December 2019

The high volume of green house gases released from petroleum refineries has contributed greatly to global warming. The crude distillation unit of a refinery being an energy-intensive unit generates high volume of greenhouse gases. Unlike solid and liquid pollutants that can easily be handled and treated, gaseous pollutants are difficult to handle once they are generated, hence an effective means of reducing their generation is paramount.Â Because of the cost penalty placed on defaulters, emission trading scheme has been an effective way of controlling the release of these obnoxious gases into the environment as refiners would seek alternative processing schemes that reduce emissions. The crude distillation unit of the refinery under study was simulated in Aspen Hysys. The unit was designed to process 125,000bpsd of a blend of three Nigerian crudes. Greenhouse gases from the unit were targeted from direct (heating sources) and indirect (electricity usage) respectively. The concept of global warming potential was adopted to estimate the carbon (iv) oxide equivalent of the greenhouse gases from the unit. A methodology to allocate emission quota to a refinery was developed and a carbon fee of $5 per tonne was placed for above- limit emissions. The crude distillation unit was found to have a base generation of 491576.27tonne/yr of carbon (iv) oxide equivalent while it pays $491,576.25per year for above-limit emission. The sensitivity analysis revealed that the gross profit is quite sensitive to carbon fee.Â Â

The purpose of this study is to find the relationship between financial ratio and EVA with fishery subsector stock return in Indonesia. The finacial ratio used in this study areÂ Current Ratio, Debt to Equity Ratio (DER), and Return on Equity (ROE) who are represent liquidity, solvency, and companies profitability. Other factor that has to be measured is Economic Value Added (EVA). EVA has been used for years to measure companies performance, however there are a lot of diferent result among researcher around the world about EVA as the best finacial peformance indicator for companies and can affect companies stock return. One of the macroeconomic factor that expected to have significant effect on stock return is exchange rate. The activity of fishery industries are circle around export and import, therefore exchange rate are expected to be the macroeconmic factor that could affect stock return. The result of this research shown that there are no significant relationship between finacial ratio, EVA, and exchange rate with stock return in fishery subsector.
Leadership in Self-organized Systems: Squaring the Circle or a New Kind of Responsibility?
Authors: Minnig Christoph , Zaengl Peter 
Published: December 2019

Current changes in society, in particular globalization, demographic trends, and changes in the labour market, have far-reaching implications for how we live and work together. Common social problems, for instance, are becoming more complex and new problematic situations continually arise. With cuts in the social sector and increasing demands for efficiency and effectiveness, overall conditions are becoming worse. Faced with these developments, social security systems are increasingly pushed to the limit and are forced to redefine their areas of responsibility. In addition, we must take account the issue of crowding-out processes in the social sphere. Large, mostly internationally operating enterprises for example are increasingly receiving performance contracts from governments in the areas of elderly care or immigrant services. It is also apparent that social service organizations are overloaded and that their established structures and historically evolved market positions are eroding. In the current discussion, we have to find answers to at least two questions within the context of developing organizations:1.Â Â Â Â Â Â Â Â Â Â Â Â How should we build organizations so that they are able to withstand or handle these challenges?2.Â Â Â Â Â Â Â Â Â Â Â Â How can we define the role of leadership in these organizations?First, we will discuss the concept of responsibility. We will then describe the different challenges that organizations face, particularly in the social sector. Based on Frederic Lalouxâ€™s (2014) model of â€œEvolutionary Organizations,â€ we will present a critical discussion of the possibilities for responsible leadership that are available to organizations in the social sector.

Published: December 2019

â€˜Geo-hazardsâ€™ is a collective term to describe hazards causing huge problems with human settlements, where the hazards are many and varied, including earthquakes, floods, windstorms, and drought, all of which are intensifying over time in large part due to climate change and population growth.Â In particular, issues of availability of â€˜safeâ€™ water are major disruptive elements frequently causing widespread incidence of diarrheal diseases both during and post, geo-hazard events. In response, arguments are described which demonstrate ceramic water filters (CWFs) have credible potential to effectively remove E.-coli (and, by similar attribute characterization), are effective in the removal of cholera. Field experience in terms of removal have been demonstrated as 94.7% removal of E-coli and all users in some applications have expressed interest in continuing use of ceramic filters beyond the trial period. Arguments are put forth, for CWFs as a Point-of-Use (POU) technology by which they can be stored and rapidly disseminated given occurrence of geo-hazards, thereby providing the opportunity to respond quickly. CWFs can be effectively stored without deterioration, are inexpensive, and easy to train recipients for their post-geo-hazard occurrence.

Published: December 2019

Package down-scaling or miniaturization has become the trend in semiconductor industry, with smaller and thinner package being the prime objective.Â Stacked dice process in semiconductor packages is now also becoming popular as semiconductor industries try to come up with products that offer multiple channels in a small IC (integrated circuit) package.Â However, as different dice are brought together, several challenges have to be overcome in terms of package design and assembly.This technical paper specifically considers the challenges encountered in the development of a compact and thinner package that incorporates multiple or stacked dice in one.Â For the case of this paper, Die1 is smaller than Die2 and must be the first one to be die bonded, making the internal construction an unbalanced stacked dice.Â Normally, stacked dice is in pyramid layout, wherein a single large die supports smaller top die.Â Nevertheless, success is measured when there is a solution to control die attach voids and eliminate or significantly minimize delamination for unbalanced stacked dice as mentioned.Â Ultimately, the paper presents the understanding of the factors involved and the package design optimization approach used to produce a successful unbalanced stacked die in a thin package using thin substrate.

Authors: Dincoglan Ferrat , Sager Omer , Demiral Seluck , Beyzadeoglu Murat 
Published: December 2019

Background: Cerebral arteriovenous malformations (AVMs) are rarely seen congenital vascular anomalies. AVMs may lead to intracranial hemorrages due to disorganized tangle of vessels. Lifetime risk of bleeding from AVMs may be significant given the diagnosis at typically earlier ages of the lifespan, and complications associated with hemorrhage may lead to substantial morbidity or mortality. Management of AVMs aims at eliminating or reducing the risk of subsequent bleeding. In this context, microvascular surgical resection, endovascular embolization and radiosurgical treatment may be used for management of AVMs.Objective: In this study, we assessed the incorporation of Magnetic Resonance Imaging (MRI) in treatment planning for AVM radiosurgery.Â Methods: We identified 25 patients receiving radiosurgery for AVMs at our institution. Radiosurgery target volumes generated by using CT-only based imaging and CT-MR fusion based imaging for each patient were evaluated.Results: Twenty five patients undergoing SRS for AVMs were evaluated for target volume determination in this study. Mean target volume was 4.9 cc (range: 1.3-15.9 cc) on CT-only imaging, 5.7 cc (range: 1.4-16.7 cc) on CT-MR fusion based imaging, and 5.9 cc (range: 1.4-16.9 cc) on consensus decision of all treating physicians with colleague peer review. Target definition based on CT-MR fusion based imaging was identical to the consensus decision of all treating physicians in majority of patients.Conclusions: Treatment planning for AVM radiosurgery may be improved by incorporating CT-MR fusion based imaging, which clearly should be supplemented with additional data from angiography. There is need for additional studies to establish a consensus on optimal target definition by multimodality imaging for SRS of AVMs.
Degradação arquitetônica e a morfologia do Bairro da Campina no centro histórico de Belém (Pará, Brasil) | Architectonic degradation and the morphology of Campina Neighbourhood in the historic center of Belém (Pará, Brazil)
Authors: Morhy Samia Saady , Lima José Júlio Ferreira 
Published: December 2019

O artigo parte do registro da localização e caracterização de imóveis com degradação arquitetônica no bairro da Campina, Centro Histórico de Belém, para análise das relações entre sua morfologia e as condições socioeconômicas responsáveis pelo processo de degradação do bairro. Busca associar aspectos da socioeconomia da área, seu histórico de ocupação, alterações nas atividades comerciais ligadas às classes populares com as condições morfológicas. A metodologia consiste no cadastramento e análise da degradação de imóveis e suas localizações quanto à acessibilidade, conforme a teoria da Sintaxe Espacial. Observa-se prevalência de imóveis degradados com estacionamentos para veículos e depósitos para mercadorias de ambulantes. A inteligibilidade da morfologia do bairro é devida à acessibilidade e a atratores, como a Feira do Ver-o-Peso, bancos e instituições. Resultados demonstram um ciclo de degradação com duas dinâmicas articuladas ligadas a fatores socioeconômicos, uma resultante da demanda por estacionamentos para veículos e depósitos para mercadorias de ambulantes espacialmente distribuídas em função dos níveis de acessibilidade veicular e outra pela distribuição de ambulantes nas ruas do bairro. Longe de uma visão determinista, o artigo conclui que as relações entre morfologia urbana e localização de imóveis degradadas constituem fenômeno que necessita ser incluído em análises de políticas urbanas associadas com políticas de preservação do patrimônio edificado.
