Internal Hernia Masquerading As Necrotizing Enterocolitis
2017
In extremely preterm infants, acute abdominal emergencies are fortunately less common with improving care. Spontaneous intestinal perforation and necrotizing enterocolitis are conditions where emergency surgery is most often needed. Conservative medical management and placement of temporary drain are often used in the initial management. Internal hernia (IH) is an uncommon cause of bowel obstruction in neonates, is difficult to diagnose and unfortunately are found only at autopsy. The presentation in preterm infants, distinction between these conditions, and the need for early diagnosis of IH are discussed.
Updating the OSPF routing protocol for communication networks by optimal decision-making over the k-shortest path algorithm
2019
Internet routing protocols such as Routing Information Protocol (RIP) pre-compute all the shortest paths by Dijkstra's algorithm (shortest path first, SPF) based on the number of hops between one node and another. Every time any communication is intended, RIP looks-up for the optimal choice in a routing table. This is a high speed method in the decision-making process but not necessary fast for data traffic as it does not take into account any real-time measure of route congestion. Open Shortest Path First (OSPF) presents a dynamic version of this problem by computing the shortest paths taking into account network features such as bandwidth, delay and load. OSPF thereby maintains link-state…
Pancreatitis aguda necrótico-hemorrágica: propósito de dos autopsias judiciales
2015
la pancreatitis necrótico-hemorrágica, es una complicación inusual y altamente mortal en los casos de inflamación de la glándula pancreática. El diagnóstico es de sospecha clínica apoyado por pruebas de laboratorio y de radiodiagnóstico. Constituye una causa excepcional de muerte súbita. Pero esta forma de presentación de pancreatitis sólo puede ser confirmada mediante el estudio anatomopatológico de la glándula, del cual se dispone en raras ocasiones. Exponemos los hallazgos macroscópicos de dos casos mortales de Pancreatitis Aguda Necro-Hemorrágica. hemorrhagic and necrotizing pancreatitis, is an unusual and highly lethal complication in cases of inflammation of the pancreatic gland. The …
Combined fuzzy TOPSIS and AHP-based methodology for the prioritization of maintenance key performance indicators: Application to an oil refinery plant
2017
A Maintenance Performance Measurement model based on the use of Maintenance Key Performance Indicators (MKPIs) is proposed in the present paper. Referring to a specific industrial context, a multi-level hierarchical structure is firstly designed to highlight the most meaningful perspectives which affect the maintenance performance. Then, MKPIs selected from the literature or properly formulated to detail some particular perspective of the investigated maintenance process are assigned to the hierarchical framework and prioritized by a Fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS) and Analytic Hierarchy Process (AHP)-based approach.
A comparison of statistical methods and multi-criteria decision making to map flood hazard susceptibility in Northern Iran
2018
In north of Iran, flood is one of the most important natural hazards that annually inflict great economic damages on humankind infrastructures and natural ecosystems. The Kiasar watershed is known as one of the critical areas in north of Iran, due to numerous floods and waste of water and soil resources, as well as related economic and ecological losses. However, a comprehensive and systematic research to identify flood-prone areas, which may help to establish management and conservation measures, has not been carried out yet. Therefore, this study tested four methods: evidential belief function (EBF), frequency ratio (FR), Technique for Order Preference by Similarity To ideal Solution (TOP…
Logotipu semiotiskā analīze un auditorijas uztveres pētījums. 2018. gada Latvijas mīlētāko zīmolu topa piemērs
2019
Bakalaura tēma ir “Logotipu semiotiskā analīze un auditorijas uztveres pētījums. 2018. gada Latvijas mīlētāko zīmolu topa piemērs”. Darbā gaitā tika atlasīti 50 zīmolu logotipi, kuriem tika veikta semiotiskā analīze, kā arī tie tika izmantoti auditorijas uztveres pētījumā. Darba teorētiskajā daļā tika aplūkota logotipu vēsture, izcelsme kā arī to veidi. Tika aplūkota arī semiotika un iespējamie zīmju uztveršanas veidi, kā arī zīmju iedalījums pēc to nozīmes. Darba metodoloģiskajā un arī empīriskajā daļā, ir aplūkotas un pielietotas tādas pētniecības metodes kā semiotiskā analīze, interneta aptauja, fokusgrupas diskusija un intervija. Darba mērķis ir noskaidrot kā cilvēki uztver zīmolu logot…
Initial results of NEXT-DEMO, a large-scale prototype of the NEXT-100 experiment
2013
NEXT-DEMO is a large-scale prototype of the NEXT-100 detector, an electroluminescent time projection chamber that will search for the neutrinoless double beta decay of Xe-136 using 100-150 kg of enriched xenon gas. NEXT-DEMO was built to prove the expected performance of NEXT-100, namely, energy resolution better than 1% FWHM at 2.5MeV and event topological reconstruction. In this paper we describe the prototype and its initial results. A resolution of 1.75% FWHM at 511 keV (which extrapolates to 0.8% FWHM at 2.5 MeV) was obtained at 10 bar pressure using a gamma-ray calibration source. Also, a basic study of the event topology along the longitudinal coordinate is presented, proving that it…
Geostatistical 3-dimensional integration of measurements of soil magnetic susceptibility.
2010
In soil magnetometry, two types of measurements are usually performed. The first type is measurements performed on the soil surface, frequently using an MS2D sensor. The second type includes measurements of magnetic susceptibility carried out in the soil profile, usually to a depth of about 30 cm. Up to now, such measurement results were analyzed separately. However, it is possible and advantageous to integrate these two types of measurements. The goal of the study was to integrate measurements of magnetic susceptibility performed on the soil surface and in the soil profile. More specifically, the goal was to obtain 3-dimensional spatial distributions of magnetic susceptibility of the topso…
Post-Mortem Immunohistochemical Evidence of β2-Adrenergic Receptor Expression in the Adrenal Gland
2019
The evidence from post-mortem biochemical studies conducted on cortisol and catecholamines suggest that analysis of the adrenal gland could provide useful information about its role in human pathophysiology and the stress response. Authors designed an immunohistochemical study on the expression of the adrenal &beta
