Injections of Particulate Steroids for Nerve Root Blockade: Ultrastructural Examination of Complicating Factors
2014
Selective nerve root block by a transforaminal approach with radiological control allows injection of an appropriate corticosteroid next to the nerve root, although it has been associated with major neurological complications in a few cases. There have been several reports in which corticosteroid injections performed at the level of the cervical or lumbar spine have led to severe spinal cord ischemic infarction. These have occurred independently of whether the procedure was performed under radiological control, in which the tip of the needle is identified to prevent vascular spreading of the solution injected.
Internet of Autonomous Vehicles: Architecture, Features, and Socio-Technological Challenges
2019
Mobility is the backbone of urban life and a vital economic factor in the development of the world. Rapid urbanization and the growth of mega-cities is bringing dramatic changes in the capabilities of vehicles. Innovative solutions like autonomy, electrification, and connectivity are on the horizon. How, then, we can provide ubiquitous connectivity to the legacy and autonomous vehicles? This paper seeks to answer this question by combining recent leaps of innovation in network virtualization with remarkable feats of wireless communications. To do so, this paper proposes a novel paradigm called the Internet of autonomous vehicles (IoAV). We begin painting the picture of IoAV by discussing th…

2020
Bakalaura darba mērķis ir izpētīt un izanalizēt iedzīvotāju ienākuma nodokļa principus, veikt iedzīvotāju ienākuma nodokļa piemērošanas analīzi algas nodokļa maksātājiem un saimnieciskās darbības veicējiem, izpētīt un izvērtēt iedzīvotāju ienākuma nodokļa plānošanas un prognozēšanas iespējas, izdarīt secinājumus un izstrādāt priekšlikumus nodokļa piemērošanā un plānošanā, un prognozēšanā. Latvijā ir noteikti 15 dažāda veida nodokļi, kurus uzliek saskaņā ar kokrētā nodokļa likumu, un kuri veido Latvijas nodokļu un nodevu sistēmu. Iedzīvotāju ienākuma nodoklis un uzņēmumu ienākuma nodoklis veido vienotu ienākuma nodokļu sistēmu. Iedzīvotāju ienākuma nodoklis ir nodoklis ar ko apliek fiziskas …
Ultra-high resolution mass separator—Application to detection of nuclear weapons tests
2009
Abstract A Penning trap-based purification process having a resolution of about 1 ppm is reported. In this context, we present for the first time a production method for the most complicated and crucially important nuclear weapons test signature, 133mXe. These pure xenon samples are required by the Comprehensive Nuclear-Test-Ban Treaty Organization to standardize and calibrate the worldwide network of xenon detectors.
Flaws in the Treaty on the Non-Proliferation of Nuclear Weapons as shown by Marshall Islands v. United Kingdom, Marshall Islands v. Pakistan, Marshal…
2020
The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) amongst its goals included both non-proliferation of nuclear weapons and nuclear disarmament. The cases Marshall Islands v. United Kingdom, Marshall Islands v. Pakistan, Marshall Islands v. India show that nuclear disarmament remains an unresolved issue. These cases refer to Article VI of NPT as being breached, and allege that the NPT can be considered to be customary international law. Furthermore, nuclear non-proliferation obligation has been fulfilled, however the obligation of nuclear disarmament has not been fulfilled. The Marshall Islands cases present three significant flaws in the NPT. The first flaw which is the ambiguous…
Numerical Investigations of an Implicit Leapfrog Time-Domain Meshless Method
2014
Numerical solution of partial differential equations governing time domain simulations in computational electromagnetics, is usually based on grid methods in space and on explicit schemes in time. A predefined grid in the problem domain and a stability step size restriction need. Recently, the authors have reformulated the meshless framework based on smoothed particle hydrodynamics, in order to be applied for time domain electromagnetic simulation. Despite the good spatial properties, the numerical explicit time integration introduces, also in a meshless context, a severe constraint. In this paper, at first, the stability condition is addressed in a general way by allowing the time step inc…
Assessment of treatment response in hepatocellular carcinoma: a review of the literature
2013
Hepatocellular carcinoma (HCC) has a high incidence all over the world. Even if the primary end point of treatment of HCC is survival, radiological response could be a surrogate end point of survival, and could have a key role in clinical management. Since 1950 several radiological response criteria have been applied; however, it was not until 2000 that specific criteria for HCC were introduced by the European Association for the Study of the Liver (EASL), and these were then standardized in 2010 with the development of the modified Response Evaluation Criteria for Solid Tumors (mRECIST) for HCC. The purpose of this brief review is to compare data in literature regarding the application an…
Are radiological endpoints surrogate outcomes of overall survival in hepatocellular carcinoma treated with transarterial chemoembolization?
2021
Background& Aims: Time to progression (TTP) and progression-free survival (PFS) are commonly used as surrogate endpoints in oncology trials. We aimed to assess the surrogacy relationship of TTP and PFS with overall survival (OS) in studies of transarterial chemoembolization (TACE) for unresectable hepatocellular carcinoma (u-HCC) by innovative methods. Methods: A search of databases for studies of TACE for u-HCC reporting both OS and TTP or PFS was performed. Individual patient data were extracted from TTP/PFS and OS Kaplan-Meier curves of TACE arms. Pooled median TTP and OS were obtained from random-effect model. The surrogate relationships of hazard ratios (HRs) and median TTP for OS …
Prevalence of impacted teeth and supernumerary teeth by radiographic evaluation in three Latin American countries: A cross-sectional study
2021
Background Supernumerary teeth are those that exceed the usual dental formula. There are different classifications depending on their anatomical location, shape and number. The objective of this study was to determine the prevalence of impacted and supernumerary teeth in a sample of panoramic radiographs from three Latin American countries. Material and Methods A retrospective and cross-sectional study with a quantitative approach, in which the radiographic observation and analysis of 2000 panoramic radiographs, provided by different radiological centers in Peru, Colombia and Bolivia were performed. An examiner, specialized in Stomatology and Oral Surgery, carried out the radiographic analy…
First tests of mechanical harvest of Origanum vulgare L.
2003
In Italy Origanum vulgare L. is cultivated only in few areas and its production does not even satisfy the national market demand. Until now the interest on this crop has been very low because of the high cost of manual harvest and bunch binding. The aim of this work is to evaluate the use of a reaper-binder (made for harvesting cereal crops) for harvesting and bunch binding Origanum vulgare L. The tests were carried out in Sicily, in the summer of 2001. The mechanical harvest was carried out using the reaper-binder unmodified, but the results were not satisfactory. The machine was then modified reducing its forward speed and cutting height, in order to improve its working productivity and h…
