Wastewater treatment and reclamation : A review of pulp and paper industry practices and opportunities

2016

The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with cost-effective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which…

Integrating Domain Knowledge in Data-Driven Earth Observation With Process Convolutions

2022

The modelling of Earth observation data is a challenging problem, typically approached by either purely mechanistic or purely data-driven methods. Mechanistic models encode the domain knowledge and physical rules governing the system. Such models, however, need the correct specification of all interactions between variables in the problem and the appropriate parameterization is a challenge in itself. On the other hand, machine learning approaches are flexible data-driven tools, able to approximate arbitrarily complex functions, but lack interpretability and struggle when data is scarce or in extrapolation regimes. In this paper, we argue that hybrid learning schemes that combine both approa…

Remote sensing and climate data as a key for understanding fasciolosis transmission in the Andes: review and update of an ongoing interdisciplinary p…

2006

Fasciolosis caused by Fasciola hepatica in various South American countries located on the slopes of the Andes has been recognized as an important public health problem. However, the importance of this zoonotic hepatic parasite was neglected until the last decade. Countries such as Peru and Bolivia are considered to be hyperendemic areas for human and animal fasciolosis, and other countries such as Chile, Ecuador, Colombia and Venezuela are also affected. At the beginning of the 1990s a multidisciplinary project was launched with the aim to shed light on the problems related to this parasitic disease in the Northern Bolivian Altiplano. A few years later, a geographic information system (GIS…

Water Depollution by Advanced Oxidation Technologies

2020

This chapter deals with water treatments by advanced oxidation processes (AOPs) based on chemical and photochemical reactions. The most used processes are described, and for each of them, the main reaction mechanisms, principles, advantages, drawbacks, performances and formation of by-products, coupled with technologies and their applications to waters and wastewater depollution, have been analysed, supporting the main results of studies published in the pertinent literature.

A mathematical study on effective wavenumber, an operative computation procedure, and its use with radiance-temperature relationships

2003

In this paper we study the existence of effective wavenumber for any sensor by means of simple mathematics. We implement a numeric algorithm, based on the developed mathematical background, into a computer program named 'srf2radi', which is freely available via anonymous File Transfer Protocol (FTP) at ftp://ftp.uv.es/pub/src/. The number of effective wavenumbers for each temperature and their accuracy are also computed and studied for NOAA-16 Advanced Very High Resolution Radiometer Version 3 (AVHRR/3) channel 4. These effective wavenumbers can be used to obtain radiance-temperature relationships with physical meaning for any sensor in user-defined temperature intervals.

"Välillä mua on melkein itkettäny mennä luennolle" : advanced language learners' experiences with foreign language anxiety

2014

Tutkielman tarkoituksena oli selvittää vieraiden kielten yliopisto-opiskelijoiden kokemuksia kielijännityksestä. Tavoitteena oli tarkastella missä tilanteissa opiskelijat kokevat kielijännitystä, mistä se heiden mielestään johtuu, millaisia vaikutuksia jännityksellä on ja millaisia keinoja opiskelijoilla on pärjätä oman jännityksen kanssa. Tutkimuksessa keskeisessä roolissa ovat opiskelijoiden omat käsitykset ja kokemukset. Kielijännitystä on tutkittu paljon mutta aiempi tutkimus on keskittynyt aloitteleviin kielten opiskelijoihin erityisesti Pohjois-Amerikkalaisessa yliopisto kontekstissa. Aiempi tutkimus on myös ollut pitkälti määrällistä tutkimusta. Tästä syystä tämä laadullinen tutkielm…

Safeguarding the Ultra-dense Networks with the aid of Physical Layer Security: A review and a case study

2016

In the wake of the extensive application of the fourth generation system, investigations of new technologies have been moving ahead vigorously to embrace the next generation communications in 2020. Thereinto, the technique of ultra-dense networks (UDNs) serves as a key enabler in meeting the roaring mobile traffic demands. With the prevalence of mobile Internet services especially those involve the mobile payment, security has gained an unprecedented amount of attention and become a highlighted feature for the fifth generation. Resource allocation, one of the most significant tools on getting over the obstacle of ubiquitous interference as well as elevating the spectrum/energy efficiency, h…

Attitudes Among Patients With Advanced Cancer Toward Euthanasia and Living Wills

2015

Euthanasia has been invariably discussed throughout Europe. In some countries, euthanasia has been legalized under specific conditions that must be fulfilled. These include a properly reported request to be considered carefully, unbearable suffering, no other reasonable alternatives, and a consultation with an independent physician. A living will, also called an advance directive, is a written document that allows a patient to give explicit instructions about medical treatments to be administered when the patient is terminally ill and unable to communicate. In Italy, euthanasia remains illegal, and living wills are not used. These issues have been the subject of constant debate.2 Such discu…
