La supervivencia final disminuyó de 100 a 27 % a 90 días del injerto.Conclusiones: La época de injertado, el origen de las yemas y el método de injerto, por separado o en interacción, son factores determinantes para el éxito de los injertos intraespecíficos con P. pseudostrobus var. oaxacana.
Menuju Dialog Antar Agama-Agama di Indonesia

Published: May 2021

Sifat kemajemukan bangsa Indonesia merupakan salah satu kekayaaan bangsa yang harus disukuri. Tetapi di lain pihak kemajemukan sering hanya dilihat sebagai suatu perbedaan yang oleh sebagian pihak dianggap sebagai sesuatu yang mengganggu, karenanya perlu “diseragamkan” keberadaannya, termasuk soal keyakinan. Itulah yang menjadi penyebab terjadinya konflik agama di Indonesia—dan ini merupakan penyebab konflik terbesar—yang terjadi, salah satunya karena keberbedaan tadi, di mana ada yang merasa bahwa agamanya yang paling benar dan menganggap agama yang lain adalah agama yang salah, kafir. Merasa bahwa agamanya lebih superior dan menganggap agama yang lain adalah inferior; sehingga memandang rendah agama ataupun kepercayaan agama lain. Anti terhadap pluralisme di Indonesia, bahkan ini dianggap sebagai sesuatu yang sesat. Inilah sifat eksklusivisme, yang menyebabkan intoleransi, kekacauan dan peperangan yang seharusnya tidak perlu terjadi.
Kepemimpinan Menurut Alkitab dan Penerapannya dalam Kepemimpinan Lembaga Kristen
Authors: Sunarto  
Published: May 2021

Alkitab banyak mencatat tentang tokoh-tokoh kepemimpinan dari satu zaman ke zaman berbeda. Kepemimpinan Kristen tidak bisa disamakan dengan kepemimpinan pada umumnya karena gaya kepemimpinan Kristen harus bertolak dari Alkitab sebagai tolok ukur kebenaran. Seorang pemimpin harus memahami sumber dan asal mula otoritas kepemimpinan. Sumber otoritas dan asal mula kepemimpinan berasal dari Allah yang berdaulat. Allah yang memilih dan memanggil seorang pemimpin untuk melakukan tugas dan tanggung jawab berdasarkan agenda kerja Allah. Karena itu kepemimpinan Kristen harus bisa menghadapi berbagai masalah dan tantangan yang muncul pada zamannya. Surat 1 Timotius 3 dan Titus 1 memberikan kualifikasi dasar bagi para penatua dan diaken yang menjadi representatif bagi kepemimpinan di gereja dan lembaga Kristen pada masa kini.
Pengkhotbah dan Peranan Roh Kudus Dalam Berkhotbah
Authors: Sunarto  
Published: May 2021

Gagasan berkhotbah pertama kali muncul bukan dimulai dari manusia, tetapi dimulai dari hati Allah sendiri. Sejak manusia yang pertama diciptakan oleh Allah, hakikat berkhotbah sudah dikerjakan oleh Allah, demikian juga ketika manusia jatuh ke dalam dosa, Allah langsung menyampaikan berita firman-Nya kepada manusia. Mandat berkhotbah akhirnya diteruskan kepada para nabi, rasul dan semua orang percaya dipanggil untuk menyampaikan kebenaran dari Allah. Dunia yang gelap oleh dosa memerlukan terang kebenaran supaya mengerti akan kehendak Allah. Berkhotbah salah satu instrumen yang dapat dipakai oleh Allah untuk menyatakan kehendak-Nya bagi manusia yang berdosa. Dalam berkhotbah ada dua aspek yang terlibat, yaitu: unsur ilahi dan insani. Ada peranan Roh Kudus dalam berkhotbah dan ada peranan manusia yang dipakai oleh Allah dalam menyampaikan kehendak-Nya.

O professor recuperador e os novos mecanismos de apoio escolar serão fundamentais no processo de recuperação de alunos. Este estudo teve como metodologia o método qualitativo por ser considerado o mais adequado aos objetivos propostos, tendo sido utilizado como instrumento para coleta de dados o questionário e a observação. Acredita-se que a pesquisa seja relevante, uma vez que podemos perceber que a interferência de um professor recuperador em sala de aula, principalmente nas quais há um número excessivo de alunos, se faz imprescindível na contribuição da formação dessas crianças. Conclui-se que a presença do professor recuperador em sala de aulas seria mais-valia na atualidade, principalmente quando se depara com salas que tem um número excessivo de alunos, como também nas salas cujo, desenvolvimentos dos educandos são bem diferentes.
Evaluación de la continuidad del cuidado brindado por médicos de atención primaria en un seguro de salud de un hospital universitario privado
Authors: Villalon Gabriel Esteban , Kopitowski Karin , Terrasa Sergio Adrian , Esteban Santiago , Ruiz Yanzi Maria Victoria 
Published: May 2021

Antecedentes. La continuidad del cuidado (CoC) suele describir en qué medida los pacientes ven al mismo profesional a lo largo del tiempo. Constituye un elemento necesario para garantizar la longitudinalidad en la atención, elemento clave de la atención primaria y de la medicina familiar en particular, entendido como el cuidado centrado en la persona a lo largo del tiempo, independientemente del tipo de problema consultado. Esta ha sido vinculada con una serie de beneficios para los pacientes y algunos indicadores duros de utilización de servicios de salud, por ejemplo visitas a la central de emergencias (CE), internaciones hospitalarias y mortalidad. En Argentina y América Latina no habíamos podido identificar estudios que dieran cuenta del nivel local de CoC o de su impacto en la utilización de los servicios de salud.
Objetivo. Cuantificar los niveles de CoC de los afiliados de un Seguro de Salud de un Hospital Universitario Privado y describir su asociación con la utilización de servicios de salud, tales como consultas a la CE e internaciones hospitalarias.
Métodos. Estudio observacional, descriptivo, de cohorte retrospectiva; realizado sobre la totalidad de afiliados que hubieran realizado al menos dos consultas programadas con un médico de atención primaria entre 2015 y 2016.
Las mediciones principales consistieron dos indicadores: el índice del proveedor usual de cuidados y el índice de continuidad del cuidado (UPC y COC, respectivamente, por sus iniciales en inglés) -cuyos valores oscilan entre 0 y 1, y se interpretan como: el paciente siempre fue atendido por diferentes médicos vs siempre por el mismo médico- y el recuento de visitas a la CE e internaciones hospitalarias.
Resultados. Fueron identificados 112.062 pacientes con una mediana de edad de 59 (P5-P95, 4 a 87) años. La medianas (P5-P95) de los indicadores de continuidad, UPC y COC, fueron 0,66 (0,25 a 1) y 0,33 (0,04 a 1), respectivamente. Se observó una asociación inversa y estadísticamente significativa entre los indicadores de CoC y la cantidad de visitas a la CE, evidenciada por una razón de incidencia decreciente de consultas contra quintilos crecientes de COC (tomando como referencia el quintilo más bajo de continuidad). Esta asociación no pudo demostrarse para las internaciones.
Conclusiones. Los niveles de CoC alcanzados y su impacto en la utilización de servicios de salud reflejan valores semejantes a los de otros estudios publicados fuera de nuestra región y podrían aportar elementos útiles para delinear estrategias tendientes a la mejora de la calidad de la atención médica.

New Correlation of Oil Compressibility at Pressures Below Bubble Point For Iraqi Crude Oil
Authors: Hassan Omar F. , Sadiq Dhefaf J. 
Published: May 2021

Oil compressibility represents a significant character in reservoir simulation, design of surface facilities and the analysis of well tests, specifically for systems below the bubble point pressure. Oil compressibility is not directly measured in the laboratory. It is usually gained indirectly from experimental data recorded in PVT reports. The relative volume from the flash test is used to calculate oil compressibility at pressures above the bubble point pressure. At pressures below the bubble point, the reservoir behavior is simulated by the differential liberation test. The solution gas-oil ratio and the oil formation volume factor from the differential liberation test are employed in the estimation of oil compressibility at pressures below the bubble point pressure This paper purposes new correlation for calculating isothermal oil compressibility coefficient at and below bubble point pressure. The formulation of oil compressibility correlation is very difficult as it depends on many variables. This property is a function of many variables such as bubble point pressure, reservoir pressure, reservoir temperature, solution gas-oil ratio, oil formation volume factor, stock-tank oil gravity, specific gravity of gas and gas formation volume factor. Standing’s (1), McCain et al. (2) and Al-Jarri's (3) correlations were submitted for testing their validity to evaluate their performance with Iraqi crude oils and to compare their results with the results of the new correlation. The achievement of the new correlations has been done using two hundreds and nine data points from twenty PVT tests that were collected from Southern Iraqi fields. The evaluation of the previous correlations has achieved with graphical and statistical methods. These checking methods show a poor agreement between the observed and the calculated values. The checking methods (graphical and statistical) explain that the new correlation that was achieved in this paper is suitable to calculate oil compressibility below bubble point pressure for Iraqi crude oils.

Effect of Pressure and Temperature Change on Undersaturated Oil Viscosity
Authors: Daway Mohammed M. 
Published: May 2021

A study has been done based on data received from one of the southern Iraqi's oil fields, consists of eighty eight experimental points of oil viscosity at known pressure and temperature above the bubble point pressure.
Fourteen formulas assumed to define the effect of pressure and temperature change on undersaturated oil viscosity. Every formula gives a value of viscosity at any temperature and pressure (above bubble point) depending on a known value of
viscosity at known pressure and temperature. Depending on the least squares method, the constants of these formulas are calculated.
A formula appeared to have the minimum average absolute error (4.8 %) with a value of correlation coefficient equal to (0.8996) is selected to be the best formula adopted in this study. The most proper formula has been compared with two correlations (Khan's correlation and Vasquez and Beggs correlation) and it appeared to be better than the both correlations.
Adsorbtion of Nitrogen Compounds from Hydrocarbon Liquids by Using Fixed Packed Bed Activated Carbon
Authors: Mohammed Mohammed Sabah 
Published: May 2021

The Extraction behavior of nitrogen compounds (quionoline, indole, and pyridine) from a liquid hydrocarbon (nonane, C9) was studied by using batch and fixed bed activated carbon experiments. The adsorption isotherm curves and the extraction percentage were determined in batch experiments in the conditions of initial concentration 20,40,60,80,and 100 ppm of either of quionoline, indole, and pyridine, fuel/(AC) ratio of 20 wt/wt, room temperature 30 ± 1°C , and stirring time of 2h.
In the fixed bed experiments the breakthrough curves were determined as a function of the following variables:

Bed height of activated carbon 3, 5, and10 cm.
Initial concentration of nitrogen compounds 50, 75, and100 ppm.
Flow rate of the feed (15, 25, and35) ml/min.
Particle Diameter of activated carbon 1.5, 1.2, and1 mm.

The adsorption capacity increases with increasing equilibrium concentration of the nitrogen compounds in the liquid phase, which is a very favorable isotherm irreversible adsorption. Also the activated carbon has very high affinity for the nitrogen compounds in the order indole < quinoline < pyridine and the conversion values were (50, 46, and42) % respectively. In fixed bed experiments the time to breakthrough point decreases with:

Decreasing in bed height.
The increase in flow rate.
The increase in initial concentration of nitrogen compounds.
There is no effect of varying the particle diameter of the activated carbon because the experimental values of the activated carbon lies in the region of the large particle size and macrospore volume and there is no gradient in the particle size.
Hydrodynamic Characteristics Effect of Foam Control in a Three-Phase Fluidized Bed Column
Authors: Fadhil Mohammad 
Published: May 2021

The present work was devoted to study the effect of operating parameters (e.g., superficial gas and liquid velocities, size of solid particles, volume percentage of particles loaded in column and type of particles) on foams, and to investigate the process of foam suppression.
The experimental apparatus was operated in continuous mode for the two phases (i.e. air and a solution of aqueous anionic surfactant). Sands which were considered as hydrophilic behavior particles were used as solid phase. A specific surface treatment was performed on hydrophilic sands particles to transfer it into hydrophobic one. These two versions of sands were used in the experimental setup respectively to study their effect on suppression of foams. The average gas holdup for the entire column was measured by means of the local gas holdup which was computed from the pressure difference in each segment of the column. Local solid concentration along the column was measured experimentally by analyzing the samples of mixture drawn from the sampling ports. From the present work it was found that: Flow regimes of multiphase system could be easily determined by utilizing local gas holdup profile measured by pressure drop transducer method. The transition from the homogenous to heterogeneous regime was advanced, from ug=4 to 2cm/s with increasing solid concentration from 10 to 20%v and decreasing average particle diameter from dp=(0.8) to (0.25) mm.
When a mixture of water/surfactant was employed in the bubble column, foam could be present depending on the input operating parameters. The fluid mechanism of foam suppression with hydrophilic particles was enhanced by a direct attack on the foam by hydrophobic particles (i.e. hydrophobic particles were more effective in retaining liquid–destroying foam than the hydrophilic particles). It was found that hydrophobic particles of 0.25 mm average diameter and 10%v loading in the reactor could reduce foaminess fraction from 0.85 to 0.15 if the liquid velocity was 0.3 cm/s. The foaminess fraction could be reduced to 0.0 if the liquid velocity increased to 0.4 cm/s. The results of this study may have abroad applications in petroleum and petrochemical industries where liquid hydrocarbons are processed.
