Radiometric correction of multispectral uas images : Evaluating the accuracy of the parrot sequoia camera and sunshine sensor

Unmanned aerial systems (UAS) carrying commercially sold multispectral sensors equipped with a sunshine sensor, such as Parrot Sequoia, enable mapping of vegetation at high spatial resolution with a large degree of flexibility in planning data collection. It is, however, a challenge to perform radiometric correction of the images to create reflectance maps (orthomosaics with surface reflectance) a

High efficient ethanol production from corn stover by modified mild alkaline pretreatment

Sodium carbonate pretreatment, an environmentally-friendly and efficient pretreatment, was used to improve solid-state ethanol production from corn stover (CS). To further enhance ethanol yield from the pretreated CS, especially at low enzyme loadings, a combined pretreatment, including steam and sodium carbonate pretreatments, was developed. The removal/modification of lignin by sodium carbonate

Methodology for developing reduced reaction mechanisms, and their use in combustion simulations

Combustion, present in a vast majority of energy and material production as well as in transportation, represents a foundation of our modern society. To improve and optimize the applications relying on combustion demand a high level of knowledge, and an ability to simulate the combustion process. To do so three-dimensional Computational Fluid Dynamic (CFD) combustion simulations can be used, whereCombustion, present in a vast majority of energy and material production as well as in transportation, represents a foundation of our modern society.

This report describes a system model for assessing and updating the condition state and reliability of bridge structures utilizing inspection and monitoring data. The system model was developed on the basis of an existing continuous single-cell prestressed concrete box girder. The system model consists of two integrated sub-models: a condition model for predicting the deterioration state of the bo

A 20-GHz Bandwidth Power Amplifier for Phased Array 5G New Radio Transmitters

A 27-47-GHz differential cascode power amplifier for millimeter-wave 5G new radio applications is presented. The PA is a three-stage design using inductively coupled impedance transformers with 31-dB nominal power gain. A device periphery ratio of 1:2:6 is adopted for predriver, driver, and final stage, respectively. A gain equalization technique was used in the interstage transformers to obtain t

Religion and Forced Displacement in Georgia

This policy report focuses on religion-state relations in Georgia and argues that competition between the Eastern Orthodox Church, the Armenian Apostolic Orthodox Church and the Muslim community have had an impact on state involvement with humanitarian programmes. The Georgian case stands out as the country experienced three waves of internal forced displacement. Each wavehas shown that religious

Identifying New Antimigraine Targets : Lessons from Molecular Biology

Primary headaches are one of the most common conditions; migraine being most prevalent. Recent work on the pathophysiology of migraine suggests a mismatch in the communication or tuning of the trigeminovascular system, leading to sensitization and the release of calcitonin gene-related peptide (CGRP). In the current Opinion, we use the up-to-date molecular understanding of mechanisms behind migrai

A semidiscrete scheme for a one-dimensional Cahn-Hilliard equation

We analyze a semidiscrete scheme for the Cahn-Hilliard equation in one space dimension, when the interface length parameter is equal to zero. We prove convergence of the scheme for a suitable class of initial data, and we identify the limit equation. We also characterize the long-time behavior of the limit solutions.

Differential associations of APOE-ε2 and APOE-ε4 alleles with PET-measured amyloid-β and tau deposition in older individuals without dementia

Purpose: To examine associations between the APOE-ε2 and APOE-ε4 alleles and core Alzheimer’s disease (AD) pathological hallmarks as measured by amyloid-β (Aβ) and tau PET in older individuals without dementia. Methods: We analyzed data from 462 ADNI participants without dementia who underwent Aβ ([18F]florbetapir or [18F]florbetaben) and tau ([18F]flortaucipir) PET, structural MRI, and cognitive

RIFM fragrance ingredient safety assessment, glyceryl monooleate, CAS Registry Number 111-03-5

The existing information supports the use of this material as described in this safety assessment. Glyceryl monooleate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that glyceryl monooleate is not genotoxic. Data on glyceryl monooleate provide a cal

Transitions between levels of dependency among older people receiving social care - a retrospective longitudinal cohort study in a Swedish municipality

BACKGROUND: Knowledge is scarce on how needs for home help and special housing evolve among older people who begin to receive support from municipal social care. The purpose of this study was to describe baseline distributions and transitions over time between levels of dependency among older persons after being granted social care in a Swedish municipality.METHODS: Based on a longitudinal cohort

Brottslingar av en mycket speciell sort. : Spionskandalen som en maktkamp mellan visselblåsare, grävande journalister och underrättelsetjänster.

Spy scandals in Western democracies can be seen as a power battle between three actors: investigative journalists, whistleblowers and the intelligence organizations at the center of the scandal. It is a conflict played out both within and outside of the court-house as the actors try to claim the label “hero” for themselves while actively trying to repudiate other labels, such as “traitor”, “spy” o

Downstream effects of polypathology on neurodegeneration of medial temporal lobe subregions

The medial temporal lobe (MTL) is a nidus for neurodegenerative pathologies and therefore an important region in which to study polypathology. We investigated associations between neurodegenerative pathologies and the thickness of different MTL subregions measured using high-resolution post-mortem MRI. Tau, TAR DNA-binding protein 43 (TDP-43), amyloid-β and α-synuclein pathology were rated on a sc
