Authors: Liu Jinjiang , Zhang Fuxing , Qian Peng , Wu Wenlin
Published: April 2021

Drilling fluid loss always occurs in fracture-porosity reservoirs and it causes severe problems. To reduce and prevent lost circulation, it is important to get to know the cause and the characteristic of drilling fluid loss. According to the approach in the reservoir simulation and well test analysis, a new model for drilling fluid loss in fracture-porosity reservoir is presented. Multi fractures in the formation and drilling fluid seepage between fracture and rock matrix have been considered in the model. The governing equations are derived based on the principle of conservation of mass. The model is solved numerically using Newton-Raphson iterative method. The obtained results indicate that drilling fluid leak-off has great influence on the total leakage volume. It is necessary to consider the impact of the drilling fluid leak-off. In addition, influence of formation properties, such as fracture stiffness, rock matrix porosity, rock matrix permeability, and operation factors, such as pressure difference between wellbore and formation, are also analysed in detail in the paper which could help better understand the factors that influence the drilling fluid loss during drilling operation.

Objetivo: Compreender as complicações relacionadas entre o pneumotórax e os pacientes idosos com DPOC, bem como, as abordagens terapêuticas e a importância do acompanhamento individualizado desse grupo de pacientes. Revisão bibliográfica: O pneumotórax é uma urgência médica definida pela apresentação de ar na cavidade pleural. É classificado como espontâneo ou não espontâneo originado traumaticamente. O pneumotórax espontâneo é subdividido em primário, quando há ausência de doenças pulmonares subjacentes e secundárias, caracterizado pela presença de patologias pulmonares associadas como a DPOC. A DPOC surge como condição prévia para complicações em pacientes idosos com pneumotórax espontâneo secundário. Dentre as complicações do pneumotórax em pacientes idosos com DPOC, temos a piora nas funções cardiopulmonares, insuficiência respiratória crônica, longos tratamentos com oxigenoterapia e até o óbito. Diante da sensibilidade desse quadro é necessária uma avaliação adequada e individualizada desse pneumotórax, principalmente porque a grande maioria dos pacientes com DPOC são idosos. Considerações finais: Assim, para evitar as complicações graves nesse grupo específico, é necessária a reavaliação e rastreamento da DPOC nessa população, a fim de que o tratamento seja realizado o mais precoce, adequado e individualizado possível, evitando, desta forma, não só o desenvolvimento do pneumotórax, mas, também, das complicações mais graves e fatais.

Published: April 2021

Предложен метод оптической спектроскопии для оценки качества растворителя, на примере вазелинового масла (ВМ), используемого при гель-формованиии сверхвысокомолекулярного полиэтилена (СВМПЭ). Метод основан на анализе упруго рассеянного света от частиц загрязнителя в ВМ. С помощью этого метода удалось определить средний размер рассеивающих частиц и их распределение по размерам. Методы динамического светорассеяния (ДСР) и оптической микроскопии подтвердили данные о среднем размере частиц загрязнителя в ВМ и их распределении по размерам, полученные методом оптической спектроскопии.

A method of optical spectroscopy for evaluating the quality of a solvent is proposed, using the example of vaseline oil (VM) used in gel molding of ultra-high molecular weight polyethylene (UHMWPE). The method is based on the analysis of elastically scattered light from pollutant particles in a VM. Using this method, it was possible to determine the average size of scattering particles and their size distribution. The methods of dynamic light scattering (DLS) and optical microscopy have confirmed the data on the average size of pollutant particles in VM and their size distribution obtained by optical spectroscopy.

RELASI TIPO-MORFOLOGI CANDI HINDU DAN BUDDHA PADA ERA MATARAM KUNO
Authors: ; Rahadhian P. Herwindo Marcell Andrew Tuyu
Published: April 2021

Abstrak

Mataram Kuno merupakan salah satu kerajaan tertua di pulau Jawa. Pada era ini, pembangunan candi berkembang pesat. Kerajaan Mataram Kuno berdiri dibawah dua kekuasaaan wangsa. Pertama, oleh wangsa Sanjaya yang menganut ajaran Hindu. Kedua, oleh wangsa Sailendra yang menganut ajaran Buddha, namun pada pertengahan wangsa ini ajaran Hindu kembali masuk dan eksis dalam kehidupan rakyatnya. Wangsa atau dinasti yang ada melahirkan arsitektur candi yang dapat dibagi menjadi dua aliran, yaitu aliran Hindu dan aliran Buddha. Walaupun memiliki dua aliran yang berbeda, terdapat beberapa kejanggalan dari identitas arsitektur yang ada pada kedua candi tersebut. Hal yang pertama terlihat jelas adalah dari tata letak candi-candi tersebut, dimana kita dapat melihat beberapa candi Hindu dan Buddha yang letaknya berdekatan bahkan dalam satu kompleks percandian yang sama. Selain itu, diduga terdapat juga kesamaan beberapa elemen pada candi yang bercorak Hindu maupun Buddha pada masa itu. Penelitian ini dilakukan untuk mengetahui relasi antara kedua aliran tersebut dalam pembangunan candi satu sama lain. 

Penelitian menggunakan metode deskriptif dengan pendekatan kualitatif dengan cara mendeskripsikan kajian tipo-morfologi candi Hindu dan candi Buddha pada era Mataram Kuno,  lalu membandingkan keduanya. Data dikumpulkan dengan cara observasi lapangan dan studi pustaka.

Hasilnya ditemukannya persamaan dan perbedaan yang terdapat dalam kajian tipo-morfologi arsitektur candi Hindu dan Buddha pada masa itu. Berdasarkan persamaan dan perbedaan tersebut, penulis menyimpulkan beberapa relasi yang terjadi antara ajaran Hindu dan ajaran Buddha terhadap perancangan candi Hindu dan Buddha pada era Mataram Kuno. Penulis menyimpulkan bahwa relasi dapat ditemukan pada aspek sosok dan ornamentasi, sedangkan perbedaan dapat ditemukan pada aspek tata massa dan tata ruang. Namun perlu ditegaskan bahwa ada kasus khusus dimana dapat ditemukan relasi antara kedua ajaran tersebut, yaitu pada candi Prambanan. Pada kasus ini, dapat dilihat bahwa terjadi pencampuran kedua ajaran tersebut dalam perancangan arsitekturnya. Hal ini dapat dilihat sebagai titik mulainya akulturasi arsitektur candi di Nusantara.

PENGARUH KEMIRINGAN ATRIUM TERHADAP PERFORMA PENCAHAYAAN ALAMI PADA RUANGAN SEKITAR ATRIUM
Authors: ; Ryani Gunawan Safarah Putri Ma’wa
Published: April 2021

Abstrak

Sejak masa architectural re-establishment pada tahun 1970, atrium telah digunakan sebagai upaya untuk mengkonservasi energi dari sisi pencahayaan alami maupun penghawaan alami. Namun penggunaan atrium sebagai salah satu media penetrasi pencahayaan alami ke dalam bangunan masih memiliki kekurangan, yakni tingkat pencahayaan alaminya yang semakin berkurang jika semakin jauh dari sumber, baik secara horizontal maupun vertikal. Kemiringan atrium merupakan salah satu faktor geometri atrium yang dapat memengaruhi kuantitas pencahayaan alami yang masuk ke atrium dan ruangan sekitarnya secara signifikan. Perubahan variabel kemiringan atrium akan berdampak pada perubahan lebar bukaan atap pada atrium, serta munculnya area lantai ruangan sekitar atrium yang terekspos langsung ke arah bukaan atap atrium, sehingga dapat memengaruhi jumlah cahaya alami yang masuk ke ruangan sekitar atrium. Penelitian ini bertujuan untuk mengetahui besarnya pengaruh kemiringan atrium terhadap performa pencahayaan alami pada ruangan sekitar atrium yang ditinjau dari segi distribusi maupun penetrasi, serta untuk mengetahui kemiringan atrium minimal sebagai strategi peningkatan pencahayaan alami pada objek studi. Tinjauan tersebut berupa nilai average daylight factor yang mengindikasikan kemerataan dan jangkauan daylight factor yang mengindikasikan tingkat penetrasi. Objek studi yang digunakan pada penelitian ini adalah atrium Mall Festival Citylink sebagai salah satu atrium yang merepresentasikan terdapatnya area gelap pada ruangan sekitarnya.

Metode yang digunakan pada penelitian ini adalah kuantitatif – eksperimental dengan teknik pengumpulan data berupa simulasi pada ruang virtual. Program komputer Rhinoceros & Grasshopper for Rhino digunakan sebagai visualisasi dan generasi 3D-model, sementara plug-in Honeybee dan Ladybug for Grasshopper digunakan sebagai media simulasi pencahayaan alami. Data yang diperoleh digabungkan dalam program Microsoft Excel dan dianalisa menggunakan program JMP untuk melihat korelasi, signifikansi, dan determinasi antar variabel penelitian.

Melalui hasil simulasi, didapat kesimpulan bahwa pada kondisi eksisting objek studi, dua lantai terendahnya belum memenuhi standar BREEAM (average daylight factor 2%) dan standar LEED (jangkauan daylight factor 2% sebesar 75% dari total kedalaman ruangan sekitar atrium). Untuk memenuhi standar BREEAM, atrium cukup memiliki kemiringan minimal 7° atau kemiringan yang disarankan 10°. Tetapi angka kemiringan ini belum cukup untuk memenuhi standar jangkauan daylight factor yang disyaratkan LEED. Agar seluruh lantai ruangan sekitar atrium memenuhi standar LEED, dibutuhkan kemiringan minimal 11° atau kemiringan yang disarankan 15°. 

 

Kata-kata kunci: kemiringan, ruangan sekitar atrium, average daylight factor, jangkauan daylight factor, atrium Mall Festival Citylink.

However, when traced, it turns out this church is a new church that was built in 2007 by applying the Style of Gothic Architecture on the building. The application of elements of gothic architecture is not only visible from the outside of the church, but also on the inside of the church. For that, it will be further investigated about the application of any gothic elements contained in the study object.Gothic architectural elements are divided into several periods based on its development, ranging from Early Gothic, High Gothic, Late Gothic to Gothic Revival or Neo-Gothic. Gothic architectural elements have different characteristics and characters in each period of development. In this research, discussed theories about elements in gothic architecture based on its development. There are 17 elements analyzed in this research. These seventeen elements are summarized into three major sections covering the structural elements, non-structural elements, and spatial arrangements. Analysis of the application of gothic architectural elements to the Church of St. Laurensius begins by describing the elements present in the study object and then compared with the gothic architectural elements of the gothic period described in the second chapter. Based on the results of the analysis, it can be seen that from 17 elements observed, 12 elements of which are adapted from the building elements contained in the period of neo-gothic architecture.  Key Words: Gothic, Period, Element, Architecture, Neo-Gothic
KOMPARASI TATA MASSA, RUANG, ORNAMEN KUIL HINDU INDIA SELATAN DENGAN CANDI JAWA
Authors: Laurentia ; Yuswadi Saliya Finna
Published: April 2021

Abstrak- Agama Hindu pertama kali muncul di India yang kemudian masuk ke Indonesia. Salah satu buktinya  dapat terlihat dari ditemukannya prasasti yang bertuliskan huruf Pallawa. Pallawa sendiri merupakan salah satu  kerajaan yang pernah berkuasa di India Selatan. Hubungan antara India dengan Indonesia ini melebar hingga ke bidang arsitektur. Apabila dilihat secara sosok sekilas, bentuk kuil pada era Kerajaan Pallawa di abad ke 7  memiliki kemiripan dengan candi era klasik tua di Jawa. Dari adanya kemiripian ini, kuil di India Selatan menarik untuk dibandingkan dengan candi di Indonesia. Tujuan penelitian ini adalah untuk melihat perbedaan dan  persamaan apa saja yang dapat ditemukan dari kuil di India Selatan dan candi di Indonesia apabila dilihat dari  tata massa, ruang dan ornamennya. Penelitian ini menggunakan metode deskriptif dengan pendekatan kualitatif. Pertama, data tentang objek  dikumpulkan dari literatur dan kunjungan langsung ke lapangan. Setelah itu, data dideskripsikan untuk kemudian  dianalisis menggunakan teori yang relevan. Tata massa dan ruang pada masing-masing objek dianalisis  menggunakan teori organisasi ruang dan prinsip penyusunan. Sedangkan ornamen pada masing-masing objek dianalisis sesuai dengan teori pembagian elemen dalam sebuah kuil. Baru kemudian data tersebut dibandingkan  antara kuil di India dengan candi di Indonesia. Hasilnya ditemukan kesamaan pola tatanan massa pada kuil di India Selatan dan candi di Indonesia. Ada  dua pola tatanan massa yang ditemukan yaitu, pola tata massa berjejer dan pola tata massa berhadapan satu-satu.  Apabila dilihat dari kronologis waktu didirikannya kuil atau candi, pola tata massa berjejer sudah ada terlebih  dahulu pada kuil di India, sedangkan pola tata massa berhadapan satu-satu terlebih dahulu ditemukan di Indonesia.  Kedua pola ini sama-sama bisa ditemukan di India maupun di Indonesia. Hal ini menunjukkan adanya relasi atau  hubungan timbal balik antara arsitektur India dengan Indonesia. Sedangkan dari tata ruang, hasil analisis  menunjukkan perbedaan antara kuil di India dengan candi di Indonesia. Ruang yang digunakan untuk aktivitas  beribadah di India bentuknya ternaungi maupun terlingkupi, sedangkan di Indonesia berupa ruangan terbuka. Hal  ini kemungkinan ada kaitannya dengan perbedaan iklim antara Indonesia dengan India. Dari sisi ornamen yang  digunakan, ditemukan lebih banyak perbedaan dibandingkan persamaan antara kuil di India dengan candi di  Indonesia.

Published: April 2021

The quality of honey produced by stingless bees can be affected by a variety of factors.
Different seasons may have an influence on stingless bee behaviour while different flower
sources may affect the properties of stingless bee honey. Thus, this study aimed to
determine the antioxidant and antimicrobial properties of stingless bee honey from
different multifloral sources collected during dry and rainy seasons. Honey was collected
from hives placed in two different areas with multifloral (area A and B). The difference
between these areas was area A only planted with two types of flowers (with stevia) and
area B with more than two flowers. Pollen in the honey samples was identified to confirm
the seasonal variations. The antioxidative potential of the honey samples was determined
using total phenolic content (TPC), DPPH and FRAP assays and total carotenoid content
(TCC). Antimicrobial properties were analysed using well diffusion method (mm) against
the foodborne pathogens Escherichia coli, Staphylococcus aureus, Listeria
monocytogenes and Salmonella enterica serovar Typhimurium. The results revealed that
honey harvested during the dry season showed higher antioxidant properties compared to
those harvested in the rainy season. The highest antioxidant activities were measured in
honey samples taken from area B. Nevertheless, honey harvested in both seasons showed
antimicrobial properties against all tested food pathogens, with the dry season samples
showing the highest inhibition. Surprisingly, only honey from area A present showed no
antimicrobial effect against E. coli. This study showed that the antioxidant and
antimicrobial properties of multifloral stingless bee honey are strongly affected by
seasonal differences and the distribution of the flowering plant

The Didactic Mediation of Authorial Texts and Reader-effect in the Initial Education of Biology Teachers
Authors: Palcha Leandro Siqueira , Oliveira Odisséa Boaventura de
Published: April 2021

This paper presents the results of research carried out in a Biology teacher education program at a Brazilian public university, during the performance of supervised internship in high schools. From the epistemic framework of Discourse Analysis with a French strand, the discursive positions (of teacher and student) were analyzed in the mediation promoted by trainee undergraduates when using their authorial texts in Biology classes. Our data sources were the teaching projects containing authorial texts, a field journal, and classes’ video records. The results demonstrate that when considering the subject positions (author and reader), the trainees involved students in the activity of mediation and reading comics, structuring their practices within a controversial approach to the pedagogical discourse. Finally, we indicate to the research area the relevance of a discursive basis in studies on the role of reading and language in Science Education and, above all, to insert it as a relevant topic to be discussed.
Investigation of the Distribution of the Daytime Employed Population of Yangon, Myanmar, with and without the Impact of Work from Home
Authors: Aung Ye Wint , Myint San San
Published: April 2021

Work from home (WFH) has gradually become more popular since COVID-19 started its transmission in Myanmar during the first quarter of 2020. Its consequence was a re-evaluation of the culture of workplaces and a significant change has occurred to the pattern of daytime employment distribution. In this paper, the network distribution model was built with three constraints, Distribution Bias 1, 2, and 3. These biases were determined through questionnaires, survey data collections of responses from Yangonites, and geographical data of urban employment cores. These percentile biases influenced the amount of employed population per distribution times and gave rise to two results. One was the ordinary daytime employed population and another was the improved daytime employed distribution (considering WFH). These two results were compared and contrasted with coefficient of variations, t-tests, and other correlation methods to determine the effect of WFH on the daytime employed population. With survey data, it was clarified that majorities in Yangon do favor work from home as an alternative option for future employment. Subsequently, the compared results revealed that work from home significantly decreased the amount of employment distribution and the amount of such decrements were more consistent and had less variations, hence reducing cramming during daytime distribution.

Se evaluó la utilización de la harina de algarrobo, sustituyendo parcialmente al maíz en el balanceado con niveles de 7, 14 y 21 %, para la alimentación de conejos en crecimiento y engorde. Se trabajó bajo un diseño completamente aleatorizado con 40 conejos neozelandés distribuido en los tres tratamientos a base de harina de algarrobo frente a un tratamiento control,  con 5 repeticiones y el tamaño de la unidad experimental fue de un animal por jaula. Al final de la investigación se determinó que el mejor peso final y la mejor ganancia de peso lo registró el nivel de 14 % de harina de algarrobo con 2,775 y 2,277 kg. En cuanto al consumo de alimento las mejores respuestas se registraron en los niveles 14 y 21 % con 5,591 y 5,473 kg ms. La conversión alimenticia más eficiente con 2.469 y el mejor rendimiento a la canal con 64.51 % fue también para el nivel 14 %. En lo relacionado al factor sexo hubo una supremacía de los machos en relación a las hembras en el peso final, ganancia de peso, conversión alimenticia y el peso a la canal. En lo referente al indicador beneficio/costo la mejor utilidad fue para el nivel 14 % con 1:33. Por lo cual se recomienda la utilización del 14 % de harina de algarrobo en sustitución del maíz para la alimentación de conejos en las etapas de crecimiento y engorde. The use of carob flour was evaluated, partially replacing the corn in the balanced feed with levels of 7, 14 and 21%, for the Feeding of growing and fattening rabbits. A completely randomized design with 40 New Zealand rabbits distributed in the three treatments based on locust bean meal versus a control treatment was used, with 5 replicates and the size of the experimental unit was one animal per cage. At the end of the investigation it was determined that the best final weight and the best weight gain was recorded at the level of 14% of carob flour with 2,775 and 2.277 kg. Regarding food consumption the best responses were recorded at the levels 14 and 21% with 5,591 and 5.473 kg Dry Weight (DW). The most efficient feed conversion with 2.469 and the best yield to the channel with 64.51% was also for the 14 % level. Regarding the sex factor, there was supremacy of males in relation to females in the final weight, weight gain, feed conversion and weight to the carcass. Regarding the indicator profit / cost the best profit was for level 14% with 1:33. Therefore it is recommended the use of 14% of locust bean meal in substitution of corn for the feeding of rabbits in the stages of growth and fattening.

El presente artículo tiene como objetivo analizar el Sistema de evaluación, seguimiento y acreditación de la calidad educativa en Venezuela. Se investiga si la creación de este sistema ha sido el resultado de una política enmarcada en la mejora de la calidad en la educación superior. La metodología utilizada fue un estudio documental aplicando la técnica del fichaje bibliográfico, a partir de la cual se desarrollaron los núcleos teóricos. A los fines del análisis, se planteó el trabajo en cuatro partes: la primera describe la  calidad educativa en las universidades venezolanas. En la segunda se refiere a la evaluación de las universidades venezolanas. En una tercera el sistema de evaluación, seguimiento y acreditación del sector universitario. Finalmente, se reflexiona acerca de los logros obtenidos en torno a la evaluación de las instituciones de educación superior y los desafíos pendientes que se consideran claves para alcanzar una educación superior de calidad.  Se concluye que a pesar de los múltiples intentos por parte de los organismos gubernamentales y las universidades, hasta el año 2016 son pocos los avances y resultados que permitan implantar un sistema para evaluar la calidad educativa de la educación superior venezolana. This article aims to analyze the evaluation system, monitoring and accreditation of educational quality in Venezuela. It investigates whether the creation of this system has been the result of a policy framed in the improvement of quality in higher education. The methodology used was a documentary study using the technique of bibliographic signing, from which the theoretical nuclei were developed. For the purposes of analysis, it was split into four parts: the first describes the quality of education in Venezuelan universities. The second part was about the evaluation of Venezuelan universities. The third was concerned about the evaluation system, monitoring and accreditation of the university sector. Finally, I reflect on the achievements regarding the evaluation of higher education institutions and the challenges that are considered key to achieving a higher quality education. It is concluded that despite multiple attempts by government agencies and universities until 2016, little progress and results have been reached to allow implementation of a system for evaluating the quality of higher education in Venezuela.

Castor seeds were processed and the oil was extracted from the paste by cold pressing and the yield obtained was 42.80%. Moisture content of 4.38% was found. The crude oil was obtained as clear, viscous, pale-yellow liquid. of crude castor oil with methanol to produce in the presence of calcium oxide (CaO) as a catalyst was carried out. This study the fuel properties of ; the FTIR spectrum for the revealed the functional groups with characteristics bands, C=O, (CH2) n-, C-O, C=C, OH and C-H in the spectrum. From the result of the FTIR and GC-MS, the methyl ester groups present in the produced was determined and 9-Octadecenoic acid-12-hydroxy- methyl ester was identified as the most abundant compound in the which have all the functional groups as revealed by the FTIR. The experimental design as well as statistical analysis were done and using Response Surface Methodology (RSM) design expert 12.0 version software which was also used for the optimization of the three process parameters. The optimum conditions for production were a reaction temperature of 620C, methanol to oil ratio of 11:1 and a catalyst of 3.5 of oil at 1hour. The content under these optimum conditions was 54%. R2 value of 0.9996 was obtained showing good fitting

Abstract: Coffee production with shade trees is important to improve growth and quality of coffee, sustain and restore agroecology and nature based agroforestry practices. The trial was conducted at Mechara Agricultural Research Center (on station) in DaroLebu District of West Hararghe Zone, Oromia, Ethiopia. The study was intended to evaluate the influence of coffee shade trees on growth performance, yield and quality of coffee (Coffea arabica L.) under the canopy of Erytherina absinica, Cordia africana and Acacia sieberiana. The design was Randomized complete block design with three replications. The outcome had been observed a significant value at (p<0.05) probability level, non- significant value at (p>0.05) probability level and highly significance value at (p<0.01) probability level between treatments. Statistically significant and non- significant differences were observed between shaded and unshaded as well as within shaded effect based on the given parameters. Integration of shade in coffee farming system created creditable promising in producing organic coffee. Shade utility could be confirmed as to be ecologically sustainable, economically viable and socially acceptable practice. In so doing that, the effect of Erytherina absinica, Cordia africana shade trees illustrated the highest mean value in most parameters, while the least one is under the Acacia sieberiana shade tree. So the effect of Erytherina absinica mean observed with the highest value on total bearing plants 60%, thousand seed weight 59% and yield in Quintal per hectare 47.4% greater than the least treatments’ mean value based on growth parameters. On the other hand, the effect of Erytherina absinica mean observed with the higher value on aromatic intensity 46.4%, aromatic quality 87.2%, acidity 92.4%, body 93.5%, flavors 88.6% and overall quality 88.6% than the least treatments’ mean value, and also the effect of un-shade mean observed with the higher value on astringency 68.8% and bitterness 93.5% than the least treatments’ mean value based on organoleptic parameters. The highest mean value of Erytherina absinica observed on total bearing plants 12.1, thousand seed weight 130 gram and yield in Quintal per hectare 5.7 based on growth parameters, while based on organoleptic parameters, the highest mean value observed under the effect of Erytherina absinica shade tree on aromatic intensity 4.5, aromatic quality 3.9, acidity 7.9, body 7.7, flavors 7.9 and overall quality 7.9. Therefore, based on the most treatments’ parameters, to be the best shade tree was Erythrina abyssinica followed by cordia africana. Commonly, the dynamic indication of the treatment’s means difference were indicated between shaded and unshaded rather than within shaded means variation at most treatments’ parameters.

The purpose of the study was to study the pulmonary vessels in patients with pulmonary hypertension using Computed Tomography scan (CT) This is a prospective ,analytical study. this study was conducted at Khartoum Hospital (Sudan); in the period between November 2020 - January 2021 a sample of (100) patients with clinically diagnosed as pulmonary hypertension was enrolled, their mean ages were (47.92 ± 19.03) years, the sample included both genders, (42) patients were females while (58) were males and their ages were ranged from (3 - 80) years old. (CTPA) scans were acquired, all patients were examined by using multislice (CT) scanner, the data collected by special designed sheet from findings and analyzed statistically by using an (SPSS) Statistics software package.

The sample was directed to study the relationship of pulmonary hypertension with the presence of pulmonary vessels measurements; the patient's age and gender correlation with the pulmonary hypertension were investigated. The results find that the right and left main pulmonary arteries diameters changes were found to be significantly related to the presence of pulmonary hypertension, while there was no significant difference in the main pulmonary artery diameters measurements. The study concluded that CT for pulmonary artery plays an important role in the diagnostic evaluation of patients with pulmonary hypertension this due to it is easily accessible and excellent non-invasive method for the visualization and measurement of pulmonary artery and to know the possible cause of pulmonary hypertension.
