Effects of three leafy vegetables on the growth performance of Giant African Snail Achatina (Lissachatina) fulica
(2019-06-07)
This present research was performed to evaluate the effects of three leafy vegetable diets [bitter leaf (Vernonia amygdalina), fluted pumpkin leaf (Telfairia occidentalis) and pawpaw leaf (Carica papaya)] on the growth performance of Giant African Snail (Achatina fulica). A total of ninety (90) A. fulica were used for the study. Thirty (30) snails each were subjected to three different dietary treatments in three replicates of 10 snails per replicate and fed with the fresh leaves of these vegetables over a period of ...

Crack path predictions in fiber reinforced composites
(2017-09-06)
Composite materials exhibit beneficial features compared to conventional engineering material, e.g. a comparable strength and a reduced weight at the same time. To fully exploit these beneficial properties within technical structures, fracture mechanical concepts must be taken into account. The global fracture behavior in composite materials is related to the local delamination at interfaces between matrix and inclusion as well as the local fracture behaviors of the constituents. Because of their structure, the global ...

Die Welt in Karten. Umbrüche und Kontinuitäten im Mittelalter
(2017-06-28)
This paper addresses the changes and continuities within the wide range of cartographic practices that existed in the Middle Ages. Following introductory thoughts on methodological issues, the text focuses on three different types of maps, all of which represent the world in its entirety: schematic maps, world maps and nautical charts. Within different texts, as independent artifacts or as atlases, these maps were employed for diverse purposes, such as the representation of fundamental principles, of encyclopaedic ...

The impact of uncertainty on smallholder farmers' income in Kyrgyzstan
(2019-12-12)
The farming systems in the mountain areas of Kyrgyzstan are primarily characterised by small-scale crop and livestock activities. Farmers are faced with several environmental, socio-economic and political challenges and constraints that result in significant uncertainties affecting their operations. This paper attempts to model how various sources of uncertainty collectively affected the smallholders’ farm incomes during a mid-term horizon using Monte Carlo simulation. The analyses were based on data collected through ...

Equivalence of Reading and Listening Comprehension Across Test Media
(2011-09-28)
Whether an ability test delivered on either paper or computer provides the same information is an important question in applied psychometrics. Besides the validity, it is also the fairness of a measure that is at stake if the test medium affects performance. This study provides a comprehensive review of existing equivalence research in the field of reading and listening comprehension in English as a foreign language and specifies factors that are likely to have an impact on equivalence. Taking into account these ...

A pilot investigation of the relationship between climate variability and milk compounds under the bootstrap technique
(2015)
This study analyzes the linear relationship between climate variables and milk components in Iran by applying bootstrapping to include and assess the uncertainty. The climate parameters, Temperature Humidity Index (THI) and Equivalent Temperature Index (ETI) are computed from the NASA-Modern Era Retrospective-Analysis for Research and Applications (NASA-MERRA) reanalysis (2002–2010). Milk data for fat, protein (measured on fresh matter bases), and milk yield are taken from 936,227 milk records for the same period, ...

Immer noch und immer wieder – Streit um den Status von DRK-Krankenschwestern – Überlegungen nach der Lektüre einer Entscheidungsanmerkung Bernd von Maydells
(2018)
Viele tausend Schwestern des Deutschen Roten Kreuzes arbeiten noch heute in deutschen Krankenhäusern und in der Krankenpflege. Sie tun dies meist auf der Grundlage sogenannter Gestellungsverträge zwischen ihrer jeweiligen Schwesternschaft und dem Krankenhausträger. Der arbeitsrechtliche Status der DRK-Schwestern ist seit Jahrzehnten hochumstritten. Ein Aspekt dieser komplexen Problematik betrifft die Frage, ob solche Schwestern, die aufgrund von Gestellungsverträgen dauerhaft in Krankenhäusern arbeiten, in Bezug auf ...

Las tradiciones discursivas, la pragmalingüística y la lingüística del discurso
(2017)
El concepto de tradición discursiva desarrollado por la lingüística románica es central para una lingüística de enfoque cultural. Este concepto se basa en el modelo coseriano de la competencia lingüística, del cual se deduce la definición de las tradiciones discursivas. Una cuestión central de la lingüística con enfoque cultural es saber según qué principios, reglas y tradiciones se rigen los hablantes al realizar tareas comunicativas. El modelo de Coseriu abarca la sistematicidad lingüística de estas reglas y ...

Fusion of Ultrasonic and Spectral Sensor Data for Improving the Estimation of Biomass in Grasslands with Heterogeneous Sward Structure
(2017-01-21)
An accurate estimation of biomass is needed to understand the spatio-temporal changes of forage resources in pasture ecosystems and to support grazing management decisions. A timely evaluation of biomass is challenging, as it requires efficient means such as technical sensing methods to assess numerous data and create continuous maps. In order to calibrate ultrasonic and spectral sensors, a field experiment with heterogeneous pastures continuously stocked by cows at three grazing intensities was conducted. Sensor ...

Competitive interaction between guava and weeds: Effect on initial growth
(2019-12-03)
Guava (Psidium guajava L.) is one of the 50 most consumed fruits in the world. However, weed competition compromises fruit production in cultivation areas. Thus, this work aimed to evaluate the competitive interaction between guava plants and common infesting species on initial growth. Guava seedlings were cultivated during 60 days with Bidens subalternans DC., Waltheria indica L. or Commelina benghalensis L. in a randomized block design with four replicates. The experiment was conducted under greenhouse condition ...
