High seedling recruitment of indigenous tree species in forest plantations in Kakamega Forest, western Kenya
2009
Tree plantations are often used to compensate for the destruction and conversion of natural forests in the tropics. An important question is whether these plantations allow for the regeneration of indigenous tree species and are expected to transform into more natural forests in the future. To evaluate the potential of differently managed forest types for seedling recruitment of indigenous tree species we studied structural characteristics as well as tree and seedling communities in stands of natural forest, different types of tree plantations and secondary forest in Kakamega Forest, western Kenya. Forest types differed considerably in structural characteristics and tree composition with st…
Listado taxonómico comentado de los Capitélidos (Annelida, Polychaeta) de la península Iberica, islas Chafarinas, Baleares y Canarias
2013
[EN] The present annotated checklist has been elaborated after revision of preserved materials (from the Museo Nacional de Ciencias Naturales, Madrid and the reference collection of the Marine Biology Laboratory of the University of Valencia) and published literature related to capitellids from the Iberian Peninsula, Chafarinas, Balearic and Canary Islands. Twenty-four species and subspecies belonging to thirteen genera are recognized as valid taxa. With this checklist we include some taxonomic details and information on distribution at both global and regional levels. This work includes the setal formula and diagrammatic representation of capitellid taxa treated in this study.
Analysis of Conflict Datasets and Indicators: The Case of the “Arab Spring”
2017
This chapter contains an analysis of selected indicators of legitimacy, human rights and inequality, as well as information about conflict events for eight African countries affected by the Arab Spring, namely Algeria, Egypt, Libya, Mali, Mauritania, Morocco, Sudan, and Tunisia. The analyses described in this chapter allowed the determination of plausible estimates for input parameters such as legitimacy and welfare inequality, as well as patterns of size, duration and recurrence of conflict events in these countries. These results were used for setting the values of the input parameters, and for analyzing the plausibility of the solutions in the exploration of the agent-based model describ…
Norwegian Sociology and the Recognition of the Saami Minority
2014
At a time when the Saami ethnic minority got little attention by the Norwegian public and the political authorities of the country, sociologists did much to raise public awareness about the conditions of this ethnic minority. In the postwar period of the 1950s and 1960s, sociologists of Norway focused to a large degree on social groups that fell outside the emerging welfare state. Norwegian sociology has been characterized by an approach named “problem-oriented empirism” and also by sociologists playing a vital role as public intellectuals. Sociology professor Vilhelm Aubert (1922- 88) coined the term “problem-oriented empirism” to characterize Norwegian sociology from the end of the Second…
Volcanic CO2 flux measurement at Campi Flegrei by tunable diode laser absorption spectroscopy
2014
Near-infrared room-temperature Tunable Diode Lasers (TDL) have recently found increased usage in atmospheric chemistry and air monitoring research, but applications in volcanology are still limited to a few examples. Here, we explored the potential of a commercial infrared laser unit (GasFinder 2.0 from Boreal Laser Ltd) for measurement of volcanic CO2 mixing ratios, and ultimately for estimating the volcanic CO2 flux. Our field tests were conducted at Campi Flegrei near Pozzuoli, Southern Italy, where the GasFinder was used during three campaigns in October 2012, January 2013 and May 2013 to repeatedly measure the path-integrated mixing ratios of CO2 along cross-sections of the atmospheric…
Meža melleņu antocianīnu ekstrakta bioloģisko efektu izpēte intervences pētījumā geriatrijas pacientiem
2020
Dažādos zinātniskos pētījumos antocianīni uzrāda augstus antioksidatīvos efektus, pretiekaisuma iedarbību, kā arī spēju samazināt kardiovaskulāro slimību risku. Cilvēka organismam novecojot pieaug oksidatīvais stress un tā radītie bojājumi sekmē arī iekaisuma procesu veidošanos, vienlaikus paaugstinot hronisko saslimšanu riskus geriatrijas vecuma cilvēkiem. Darba mērķis bija noskaidrot meža melleņu antocianīnu ekstraktu saturoša uztura bagātinātāja intervences ietekmi, apskatot ar novecošanos saistītu asins bioķīmisko marķieru izmaiņas geriatrijas pacientiem. Rezultāti liecina, ka pēc 4 nedēļu meža melleņu antocianīnu ekstrakta kapsulu lietošanas 2 reizes dienā (50 mg/kaps.) ir droša geriat…

2010
Il saggio segnala per la prima volta e analizza dal punto di vista linguistico e letterario una omissione ex homoeoteleuto nelle glosse interlineari ai Vangeli di Lindisfarne (Gv. 4.13-14)
COVID-19 Pandemic: New Prevention and Protection Measures
2022
As of the end of February 2021, more than 420,000,000 confirmed cases of COVID-19 have been reported worldwide, with 5,856,224 deaths. Transmission of the different genetically engineered variants of SARS-CoV-2, which have been isolated since the beginning of the pandemic, occurs from one infected person to another by the same means: the airborne route, indirect contact, and occasionally the fecal–oral route. Infection is asymptomatic or may present with flulike symptoms such as fever, cough, and mild to moderate and severe respiratory distress, requiring hospitalization and assisted ventilation support. To control the spread of COVID-19, the World Health Organization (WHO) and Centers for …
Monitorización e individualización posológica de glucocerebrosidasa en pacientes con enfermedad de Gaucher Tipo I
2018
La enfermedad de Gaucher tipo I (EG1) es una enfermedad de depósito lisosomal causada por una deficiencia de la enzima glucocerebrosidasa, cuyo tratamiento consiste en la reposición mediante la administración exógena de la enzima deficiente, denominada terapia enzimática sustitutiva(TES). Actualmente, existe una gran controversia y una elevada variabilidad en la dosificación de la TES y en los regímenes utilizados en la práctica clínica debido a la amplia variabilidad observada en la respuesta a la TES; además las modificaciones de dosis para objetivar respuesta al tratamiento se alargan entre 12-24 meses, en una terapia con un elevado impacto económico al sistema nacional de salud. Sin emb…
Neirotrofo faktoru ekspresija streptozocīna - Alcheimera slimības modelī ar muscimolu
2016
1906. gadā vācu psihiatrs un neiropatologs Aloīzs Alcheimers pirmo reizi aprakstīja 56 gadu vecumā mirušu pacienti, kura mira neskaidras slimības dēļ, pēdējo četru gadu laikā strauji zaudējot atmiņu un dažādas iemaņas. Laika gaitā, analizējot medicīniskos pierakstus un pētot mirušās pacientes smadzenes, tika noteikta amiloīdo plātņu un neirofibrilāro mezglu esamība smadzenēs, kas tika nosaukta par Alcheimera slimību (Engstrom, 2007). Alcheimera slimība ir progresējoši smadzeņu darbības traucējumi, kā rezultātā smadzenes pakāpeniski „noārdās”. Visbiežāk tā rodas cilvēkiem 65-70 gadu vecumā. Slimības attīstības gaitā attīstās negatīvas izmaiņas atmiņā, domāšanā, dažādās darbībās un uzvedībā, …
