Development of physically based liquid water schemes for Greenland firn-densification models
Authors: Verjans Vincent , Leeson Amber A. , Stevens C. Max , MacFerrin Michael , Noël Brice , van den Broeke Michiel R.
Published: July 2019

Abstract. As surface melt is increasing on the Greenland Ice Sheet (GrIS), quantifying
the retention capacity of the firn layer is critical to linking meltwater
production to meltwater runoff. Firn-densification models have so far relied
on empirical approaches to account for the percolation–refreezing process,
and more physically based representations of liquid water flow might bring
improvements to model performance. Here we implement three types of water
percolation schemes into the Community Firn Model: the bucket approach, the
Richards equation in a single domain and the Richards equation in a
dual domain, which accounts for partitioning between matrix and fast
preferential flow. We investigate their impact on firn densification at four
locations on the GrIS and compare model results with observations. We find
that for all of the flow schemes, significant discrepancies remain with
respect to observed firn density, particularly the density variability in
depth, and that inter-model differences are large (porosity of the upper 15 m firn varies by up to 47 %). The simple bucket scheme is as efficient in
replicating observed density profiles as the single-domain Richards equation,
and the most physically detailed dual-domain scheme does not necessarily
reach best agreement with observed data. However, we find that the
implementation of preferential flow simulates ice-layer formation more
reliably and allows for deeper percolation. We also find that the firn model
is more sensitive to the choice of densification scheme than to the choice
of water percolation scheme. The disagreements with observations and the
spread in model results demonstrate that progress towards an accurate
description of water flow in firn is necessary. The numerous uncertainties
about firn structure (e.g. grain size and shape, presence of ice layers) and
about its hydraulic properties, as well as the one-dimensionality of firn
models, render the implementation of physically based percolation schemes
difficult. Additionally, the performance of firn models is still affected by
the various effects affecting the densification process such as
microstructural effects, wet snow metamorphism and temperature sensitivity
when meltwater is present.
Detection and characterization of extreme wind speed ramps
Authors: Hannesdóttir Ásta , Kelly Mark
Published: July 2019

Abstract. The present study introduces a new method to characterize ramp-like wind speed fluctuations, including coherent gusts. This method combines two well-known methods: the continuous wavelet transform and the fitting of an analytical form based on the error function.
The method provides estimation of ramp amplitude and rise time, and is herein used to statistically characterize ramp-like fluctuations at three different measurement sites.
Together with the corresponding amplitude of wind direction change, the ramp amplitude and rise time variables are compared to the extreme coherent gust with direction change from the IEC wind turbine safety standard.
From the comparison we find that the observed amplitudes of the estimated fluctuations do not exceed the one prescribed in the standard, but the rise time is generally much longer, on average around 200 s. The direction change does however exceed the one prescribed in the standard several times, but for those events the rise time is a minute or more.
We also demonstrate a general pattern in the statistical behaviour of the characteristic ramp variables, noting their wind speed dependence, or lack thereof, at the different sites.

Superação IDEB: Formação Continuada De Professores Da Educação Básica
Authors: Paixão Sergio Vale da
Published: July 2019

A falta de diálogos e de conhecimentos sobre possibilidades de trabalho com projetos escolares, à luz das recentes teorias sobre metodologias inovadoras no ensino, favorecem práticas pedagógicas convencionais desprovidas de sentido para os estudantes na escola. Nesse sentido, propomos uma conversa neste texto, no intuito de socializar um projeto de extensão que realizamos há algum tempo junto a uma secretaria de educação municipal, no qual professores do ensino fundamental I estão mudando seu modo de planejar aulas e, principalmente, de trabalhar com projetos na escola. Tais mudanças são frutos de encontros de formação continuada, em que a pedagogia de projetos e as recentes teorias acerca da inovação na educação, uma vez que o assunto não foi contemplado a contento na formação inicial deste grupo de professores, segundo relato das próprias educadoras participantes são temas de trabalho. Com o projeto, temos alcançado resultados satisfatórios no exercício docente e nas avaliações com os alunos.

Dual Language Program Models and English Language Learners: An Analysis of the Literacy Results from a 50/50 and a 90/10 Model in Two California Schools
Authors: Acosta Jatnna , Williams III John , Hunt Brittany
Published: July 2019

This paper examines the literacy results of English language learners (ELLs) in two California schools following either the 50/50 or the 90/10 dual language (DL) program model. The purpose of this paper is to provide a literature review of dual language programs with an analysis of two schools’ websites and literacy assessment data in order to determine the effectiveness of each program model in establishing strong foundational literacy skills and fostering the prolonged academic success of ELLs. California provides various options for the bilingual education of its increasing immigrant population. Under the umbrella of bilingual education, dual language programs aim to provide students with instruction in two languages which will allow them to become fully bilingual and develop biliteracy skills. The intended purpose of biliteracy is for students to demonstrate reading and writing proficiency in both instructional languages. Although California implements a variety of dual language program models, this paper provides an overview and comparison of the 50/50 and 90/10 models as they are implemented in two California schools with similar demographics. This paper provides an analysis of the English Language Arts/literacy results of ELLs under both program models as depicted on the California Assessment of Student Performance and Progress to determine which model is most effective in its literacy instruction of language minority students. The findings indicate that ELLs demonstrate higher levels of literacy proficiency under the 90/10 program model. These findings have implications for native language proficiency and the preservation of the mother tongue.

Se presenta la mejora de las comprensiones de los estudiantes de grado décimo en la asignatura de Química, frente al contenido disciplinar y el desarrollo de las habilidades del pensamiento crítico mencionadas, partiendo del cambio en las prácticas pedagógicas del docente de ciencias en un ámbito rural. Por lo tanto, una organización clara y coherente en la planeación de las clases (en adelante, unidades de comprensión), las reflexiones sobre la práctica, la evaluación continua del aprendizaje y el uso de rutinas de pensamiento, conllevaron a mejorar significativamente los niveles de comprensión en los estudiantes.
Diagnóstico de bullying en escuelas focalizadas del municipio de Santa Ana
Authors: Pleitez Miguel Ángel
Published: July 2019

Este artículo presenta un diagnóstico realizado en una muestra de las escuelas focalizadas del municipio de Santa Ana como un insumo para la Unidad de Arte, Cultura, Recreación, Deportes y Ciudadanía del Ministerio de Educación, Ciencia y Tecnología (MINEDUCYT). La investigación descriptiva abordo nueve de treinta escuelas focalizadas, haciendo un total de 117 sujetos, entre estos: directivos, docentes y estudiante. El bullying no es una situación nueva; en la mayoría de los casos, se asume su existencia. Pero, lastimosamente, se carece de un cuerpo teórico-práctico que indique la forma en que este se desarrolla, a fin de poder intervenirlo y paulatinamente erradicarlo. Por esa razón, se describen las manifestaciones de este flagelo y determinan cuáles son los mecanismos vertidos en el Manual de Convivencia Escolar para su tratamiento. Este proceso, por su carácter sensible y socioeducativo, permitió encontrar manifestaciones diversas: por un lado, el temor de los directivos por considerar el fenómeno como una falencia administrativa, más que un problema social que debe ser intervenido de forma adecuada, en beneficio de toda la comunidad educativa; y, por otro lado, optimismo de parte de docentes y estudiantes, ya que se hizo visible una problemática que afecta a todos. Todo lo anterior contribuyó a la construcción de un recurso investigativo que permitirá el planteamiento de futuras acciones para intervenir el bullying de forma pronta, precisa y adecuada.

Chemical and Application Properties of Some Solvent and Water Based Coatings on Wooden Substrate
Authors: Shukla Shikhar , Pandey Krishna K. , Kumar V. S. Kishan
Published: July 2019

Wood finishes are used extensively to improve the aesthetic value and protect wood products from moisture. These organic coatings generally contain volatile organic compounds (VOC) as solvents that evaporate when the coatings cure over the surface. Due to strict legislations against these hazardous VOCs, the buyers across the globe are shifting towards products finished with water borne coats. Two of the most commonly used wood coatings in India are polyurethane and nitrocellulose (NC) lacquer. This paper aims at comparing these two wood coatings with their water borne counterparts. The study was conducted on the wood substrate of Melia dubia. Chemical characterization of the cured coats was attempted through FTIR spectroscopy. Physical appearances in terms of gloss and film thickness were also studied. Bands of urethane, urea and nitric groups were identified, which helped in understanding the changes in chemical structure of the finishes after curing. The thickness of the organic coatings was significantly higher than that of their water-borne counterparts. Gloss of water based coatings was observed to be lesser than that of their organic solvent based counterparts in either coating material. In case of lacquer, the reduction was up-to 33 %. whereas in case of PU, gloss dropped down by about 54 %.

It can be said that Integrated Information Systems (IIS) are a fundamental operating tool in modern business systems and form the basis of successful company management. The goal of our research was to determine the IT level of business operations in Croatian wood processing industry and to assess how significant it has been in enhancing its business performance. A survey method was used to collect data, which resulted in gathering predominantly small and medium-sized companies. Our results indicate an average use of IIS modalities among surveyed companies. Using cluster analysis, three types of companies were identified with respect to the degree of system implementation. Analysis of financial benefits of the IIS implementation did not find any statistically significant relationship. However, subjective impressions on non-financial indicators show that companies in all three clusters see the greatest benefit of IIS in the improved inventory efficiency and sales efficiency.

Published: July 2019

Esse artigo traz o recorrente debate relacionando a abordagem predominantemente positivista no que se refere a pesquisas em marketing e a necessidade de tornar a disciplina uma ciência consolidada. Para isso, é feito um levantamento relacionado a objetividade e subjetividade em ciências sociais, à segmentação de pesquisadores em abordagens positivistas e interpretativistas, associado à recorrente demanda de validação e acreditação de pesquisas, sobretudo qualitativas (interpretativista). Essas questões fomentam preocupações que se direcionam à resolução desses dilemas. A triangulação é vista como uma possível forma de abrandar problemas relacionados a credibilidade em pesquisas, por adotar como estratégia de investigação múltiplas formas e métodos de obtenção de informações. O procedimento metodológico seguido referiu-se à pesquisa bibliográfica, dessa forma, esse artigo pretende organizar e sistematizar as principais questões envolvidas a essas barreiras das pesquisas em marketing e mostrar os aspectos da triangulação que poderiam amenizar os problemas da hegemonia positivista na metodologia de pesquisa da área.

Published: July 2019

La atracción migratoria (reciente y acumulada) es una construcción específica de la migración interna, la cual contiene dinámicas socioeconómicas y culturales, entre otras, desde los centros rurales o urbanos, con perspectivas territoriales y regionales. En México, el indicador de la atracción migratoria reciente muestra mejores condiciones y dinámicas de la economía desde hace siete años. Por su parte, Veracruz presenta desde hace una década un importante crecimiento demográfico y de inmigración interna, además de una significativa migración hacia entidades del norte. En este contexto, el objetivo del artículo es construir indicadores de atracción migratoria y reciente a nivel nacional y para el estado de Veracruz, que sirvan como base para futuras investigaciones que profundicen en las causas y factores de la migración interna, y expliquen las dinámicas entre un territorio y otro.

The migratory attraction (recent and accumulated) is a specific construction of internal migration, which contains socio - economic and cultural dynamics, among others; from rural or urban centers, with territorial and regional perspectives. In Mexico, the indicator of recent migration attraction shows the best conditions and dynamics of the economy since seven years ago. On the other hand, Veracruz has had an important demographic and internal immigration growth since a decade, as well as an important migration towards northern entities. In this context, the objective of the article is to build indicators of mig ratory and recent attraction at the national level and for the state of Veracruz, which serve as a basis for future research that delves into the causes and factors of internal migration and explain the dynamics between one territory and another.
Inuit Symbolism of the Bearded Seal
Authors: Sonne Birgitte
Published: July 2019

The skins of the bearded seal—both dress and interior skins—were indispensable in Inuit/Yupiit technology. Converted into straps, thongs, covers, pokes, rain clothing, and underwear, the skins served to make transport possible, facilitate hunting activities, and protect people against wet and stormy weather. Similarly, the same skin objects permitted contact and exchanges with the beings of the Other Worlds, on which the earthly life of humans depended. Symbolic analysis of the characteristics of bearded seal as reflected in ritual, myth, and sayings reveals that bearded seal turns out to bear both frightening and beneficial meanings. Feared in the figure of a bogey at the height of winter, welcomed as the first seal to arrive from a great distance in early spring, inspiring reproduction and protecting Raven in renewing the earth at equinoxes, bearded seal made the Inuit/Yupiit world cohere.
Une approche de recherche en écosanté peut-elle aider à résoudre les problématiques liées aux chiens à Kuujjuaq ?
Authors: Simon Audrey , Saint-Charles Johanne , Lévesque Francis , Ravel André
Published: July 2019

Au Nunavik, les politiques publiques relatives aux chiens sont calquées sur celles du sud du Québec et ne tiennent pas compte des normes ni des pratiques culturelles des Inuit. Ces politiques appellent des pratiques génératrices de tension et les interventions relatives aux chiens qui s’y appuient obtiennent, au mieux, un succès mitigé. Prenant en considération ces résultats, de même que la complexité des problématiques liées aux chiens, rapportées tant par des habitants du Nunavik que par les autorités locales et provinciales, une équipe de recherche interdisciplinaire a développé un projet utilisant l’approche écosanté en collaboration avec plusieurs partenaires locaux. Après avoir présenté le contexte entourant la gestion des chiens à Kuujjuaq, l’article propose une analyse des facteurs favorisant ou nuisant à la résolution des problématiques liées aux chiens. L’article montre ensuite la manière dont le projet écosanté interagit avec ces facteurs pour le développement de solutions efficaces et durables à ces problématiques, menant ultimement à des changements de pratiques et de politiques publiques entourant la gestion des chiens à Kuujjuaq.
Igreja provisional e ecumenismo: possibilidades e desafios em Christian Duquoc
Authors: Wolff Elias , Pereira Eliseu
Published: July 2019

As principais igrejas cristãs de hoje reconhecem o problema da divisão e a urgência de promover e resgatar a unidade dos cristãos. Entendem que a unidade é o desejo de Cristo, conforme expresso na oração sacerdotal, “Que todos sejam um” (Jo 17,21), que é um dom de Deus e uma graça do Espírito Santo. O esforço ecumênico alcançou resultados significativos ao longo do último século, especialmente se se levar em conta a situação separação e hostilidade entre as igrejas cristãs no final do século XIX e início do século XX. Mesmo assim persistem obstáculos sérios no caminho da unidade fraterna entre as igrejas. O objetivo deste artigo é analisar a tese de Christian Duquoc em Creo en la Iglesia: precariedad institucional y Reino de Dios (2001) como contribuição ao diálogo ecumênico. A tese de Duquoc é que a Igreja deve se considerar como provisória a caminho do Reino de Deus que é o perfeito. O atributo de provisoriedade não diminui a natureza da Igreja, pelo contrário a engrandece, como comunidade de Cristo que espera e dá testemunho do Reino de Deus.
TransPrise: a novel machine learning approach for eukaryotic promoter prediction
Authors: Pachganov Stepan , Murtazalieva Khalimat , Zarubin Alexei , Sokolov Dmitry , Chartier Duane , Tatarinova Tatiana V
Published: July 2019

As interest in genetic resequencing increases, so does the need for effective mathematical, computational, and statistical approaches. One of the difficult problems in genome annotation is determination of precise positions of transcription start sites. In this paper we present TransPrise - an efficient deep learning tool for prediction of positions of eukaryotic transcription start sites. TransPrise offers significant improvement over existing promoter-prediction methods. To illustrate this, we compared predictions of TransPrise with the TSSPlant approach for well annotated genome of Oryza sativa. Using a computer equipped with a graphics processing unit, the run time of TransPrise is 250 minutes on a genome of 374 Mb long. We provide the full basis for the comparison and encourage users to freely access a set of our computational tools to facilitate and streamline their own analyses. The ready-to-use Docker image with all necessary packages, models, code as well as the source code of the TransPrise algorithm are available at ( http://compubioverne.group /). The source code is ready to use and customizable to predict TSS in any eukaryotic organism.
Identification of conserved genes involved in nitrogen metabolic activities in wheat
Authors: Li Lei , Gong Hao , Sun Zhengxi , Li Tao
Published: July 2019

Nitrogen (N) plays a very important role in crop growth and development. Many N-metabolism-related genes responsive to N application have been identified in many plants such as Arabidopsis, rice and maize; however, few genes have been reported in wheat, which is one of the most widely grown crops in the world. In this study, a wheat wild type with N dependent lesion mimic (LM) and its mutants without LM were used to identify conserved N-metabolism-related genes.TaPAP,TaUPSandTaNMRwere differentially expressed among N levels both in the wild type and two of its mutants, and the expression patterns of these genes were further studied under application of three chemotypes of N (NH4+, NO3-and NH4NO3). The results showed that these genes are conserved N-metabolism-related genes andTaNMRis a novel player in N-metabolism.

Published: July 2019

A high diversity of culturable foliar endophytic fungi is known from various mangrove plants, and the core taxa include species from Colletotrichum, Pestalotiopsis, Phoma, Phomopsis, Sporomiella, among others. Since a small fraction of fungi is able to grow in culture, this study investigated the diversity of fungi associated with leaves of Acanthus ilicifolius var. xiamenensis using both isolation and metabarcoding approaches. A total of 203 isolates were cultured from surface-sterilized leaves, representing 47 different fungal species: 30 species from the winter samples (104 isolates), and 26 species from the summer samples (99 isolates). Ascomycota was dominant in both types of leaf samples, while Basidiomycota was isolated only from the summer samples. Drechslera dematioidea (10.58%, percentage of occurrence), Colletotrichum sp. 3 (7.69%) and Alternaria sp. (7.69%) were dominant in the winter samples; Fusarium oxysporum (13.13%), Diaporthe endophytica (10.10%) and Colletotrichum sp. 1 (9.09%) in the summer samples. Overall, Corynespora cassiicola (6.90%), F. oxysporum (6.40%) and Guignardia sp. (6.40%) had the highest overall percentage of occurrence. In the metabarcoding analysis, a total of 111 operational taxonomic units (OTUs) were identified from 17 leaf samples: 96 OTUs from the winter and 70 OTUs from the summer samples. Sequences belonging to Ascomycota and Basidiomycota were detected in both samples but the former phylum was dominant over the latter. Based on read abundance, taxa having the highest percentage of occurrence included Alternaria sp. (3.46%), Cladosporium delicatulum (2.56%) and Pyrenochaetopsis leptospora (1.41%) in the winter leaves, and Aureobasidium sp. (10.72%), Cladosporium sp. (7.90%), C. delicatulum (3.45%) and Hortaea werneckii (3.21%) in the summer leaves. These latter four species also had the highest overall percentage of occurrence. Combining the results from both methods, a high diversity of fungi (at least 110 species) was found associated with leaves of A. ilicifolius var. xiamenensis. Many of the fungi identified were plant pathogens and may eventually cause diseases in the host.

Rice blast disease is the most destructive disease to rice plants and can cause a lost in a yield ranging from 50 to 100%. To develop resistant genotypes, it is necessary to determine the source of resistance, the nature of resistance and the mode of gene action that gives resistance to the disease. It is known that Silicon enhances durable resistance to rice blast disease. The rice silicon uptake inheritance can be studied through crossing the high silicon uptake with low silicon uptake genotypes. Seven genotypes were crossed in a full-dialel design, two genotypes having very high silicon uptake ability, two having moderate silicon ability, two having low silicon uptake ability and the last one was having very low silicon ability. The F1 plants were selfed and F2 plants were tested for silicon uptake ability. Then genetic traits of the segregating F2 populations and their parents were analyzed in order to determine the heritability. A high narrow sense coefficient of genetic determination suggested that there was a considerable heritability of resistance for rice blast. The analysis of gene action revealed that additive gene effects contributed more than the non-additive effects for the inheritance of silicon uptake ability as indicated by high Baker’s ratio (above 0.8 and 0.3) for both silicon uptake and water lose respectively. Genotypes, GIZA182 and E20 were found to have the most desirable GCA among the genotypes used in the study.

Aim: The study investigated the possible risks associated with gastrointestinal ulcer disease by evaluating the biochemical response of three body organs; heart, kidney and liver, in gastric ulcerated rats.

Methodology: Twenty male wistar albino rats were used in the study. Gastric ulcer was induced in rats with single oral dose of 400 mg/kg body weight (b.w.) aspirin, 80 mg/kg b.w. indomethacin and 5 ml/kg b.w. acidified ethanol (40:60 v/v). Blood samples were collected into heparinized bottle and centrifuged at 4000 rpm for 10 mins to obtain the plasma. Gastric tissue, liver, kidney and heart were also collected.

Results: Oral administration of 400 mg/kg b.w. aspirin, 80 mg/kg b.w. indomethacin and 5 ml/kg b.w. acidified ethanol caused a remarkable increase in ulcer index. There was observed a significant (p<0.05) reduction in AST and ALT activities in gastric ulceration caused by aspirin (Asp), with no significant (p<0.05) change in total protein (TP) concentration, lactate dehydrogenase and creatine kinase activity. However, there was increase in creatinine and urea concentration. Acidified ethanol and Indomethacin-induced ulcerated rats showed significant (p<0.05) reduction in all other parameters except ALT and lactate dehydrogenase activities which did not show any significant (p<0.05) change. There was also observed a significant (p<0.05) increase in creatine kinase activity in indomethacin-induced ulcerated rats.

Conclusion: Overall, the result indicates a link between gastric ulcer and organ toxicity. The use of NSAIDs above the therapeutic doses in the treatment of pains and related illness as well as excess consumption of alcohol is shown to negatively impact the stomach and cause serious damage to different body organs of wistar rats.

The hormones are closely related to the emergence of gemstones contained seedlings of sugarcane, at the time of planting of the stems. The objective of this work was to evaluate the effects of the ethephon associated to the position of gemstones in the cane of sugar cane in the initial development of the culture. In March 2014, at the Rio Vermelho Plant, located in Junqueirópolis, State of São Paulo, a cane plant with a sugar cane plant was selected for seedlings with an approximate age of 11 months. Two areas with dimensions of 20x20 meters were demarcated. In one of the areas ethephon was applied. At 15 days after application, the seedlings containing 1 and 2 buds were collected to compose two independent experiments. From the area where the product was not applied, seedlings were removed for the control and application treatments of ethephon in the planting groove in pots. The gems were sent to the Faculty of Agrarian and Technological Sciences of the Paulista State University "Júlio de Mesquita Filho" - from Dracena, State of São Paulo. The seedlings came from the apex, middle and base of the canes of sugarcane. In this way, the experimental design was in a 3x3 factorial scheme, that is, the position of the seedlings in the canes of sugarcane and the modes of application of ethephon. The use of ethephon and positions of the seedlings in sugarcane stalks did not influence the Chlorophyll Index and Stomatal Conductance. The use of ethephon in the plant 15 days before planting, together with seedlings from the apex followed by the medium of the canes of sugarcane, presented better results for the ultrastructural characteristics of sugarcane foliage.

Published: July 2019

In spite the identification of stigma as a factor impeding public utilisation of HIV counselling, testing, and treatment services in Nigeria, gaps still exist in knowledge on the impact of stigma, and discrimination on adherence to medication amongst people living with HIV (PLWH). This study adopted mixed methods to examine the impact of stigma and discrimination on adherence to medication amongst PLWH in Nigeria.  A sample of 1,621 respondents was collected using multi-stage and purposive sampling methods. Structured interviews using questionnaires and in-depth interviews (using a guide) were utilised for data collection. SPSS (version 21) was used for quantitative data analysis while the qualitative data was analysed thematically. There are 46.3% men and 53.7% women respondents. Generally, their income is low, 70.7% are earning less than N25, 000 (approximately $125 USD) per month. Some of the HIV patients are stigmatised. In reaction, they avoid public places, travel long distances away from their immediate community to collect drugs and to avoid been noticed around the centers. They sometimes miss taking drugs regularly as prescribed, suffer depression and die. Stigma and discrimination impede adherence to medication amongst PLHW in Nigeria. More efforts should be made to create awareness to reduce stigma and discrimination of HIV patients, while augmenting their income to meet up with the challenges of adherence to medication. The overall benefits would be enhanced mechanism of HIV prevention, treatment and control in the study area.

Background:

This study focused on the etiology of patients with extra-adrenal primary malignancy in addition to isolated synchronous adrenal incidentalomas.

Methods:

Patients who were diagnosed as extra-adrenal primary malignancy and synchronous adrenal incidentalomas were enrolled from a single tertiary medical center from 2004 to 2014. Those with a history of malignancy or any extra-adrenal metastases at the time of diagnosis were excluded. Statistical analysis was performed to determine possible predictors for adrenal metastases.

Results:

The primary malignancies of hepatocellular carcinoma and lung cancer had higher rates of adrenal metastases than colon cancer and renal cell carcinoma. Significant predictors for adrenal metastasis were clinical T stage and adrenal mass diameters. Patients with stage T1/2 primary malignancies were more likely to have benign adrenal tumors than those with stage T3 or T4. The average adrenal mass diameters in the benign and metastatic groups were 2.87 and 4.97 cm, respectively (P = 0.001).

Conclusions:

Nearly 40% of the isolated synchronous adrenal incidentalomas in patients with newly diagnosed extra-adrenal malignancies proved to be metastases. In patients with large adrenal lesions, high mass density on computed tomography scans, or a primary malignancy at a high clinical T stage, the risk of adrenal metastasis was high.
