(2018-05-16)Unter welchen Voraussetzungen und wie gelingt erfolgreichen Müttern trotz erschwerter Lebensumstände die berufliche Eingliederung? Dieser Frage geht die vorliegende – auf empirisches Datenmaterial bezugnehmende – Arbeit ... -
Digital soil mapping using survey data and soil organic carbon dynamics in semi-arid Burkina Faso
(2018-04-27)With computer-assisted geostatistics and data mining methods, digital soil mapping (DSM) offers new possibilities for providing soil spatial information for data scarce areas such as West Africa. Such information could ... -
Studies on transmissibility, cytopathology and control of Tomato chlorotic dwarf viroid and Potato spindle tuber viroid
(2018-05-17)PSTVd and TCDVd have wide host ranges and are able to cause huge economic losses in many high-valued crops in the Solanaceous family. TCDVd has recently been detected to infect many species worldwide, posing the potential ... -
Investigation of the feeding process at concentrate feeding stations for horses in group housing
(2018-04-26)Computer-controlled concentrate feeding stations are increasingly used to guarantee an individual feed supply of group-housed horses. Blocking times caused by horses remaining in the feeding station without concentrate ... -
Perceptions and Governance of Food Insecurity Risks among Family Farmers in Southwestern Ethiopia
(2018-04-18)In Ethiopia, family farming provides livelihood for 81 percent of the population, and accounts for over 96 percent of total agricultural production. However, family farmers often operate under continuous threats of complex ... -
Genetic and physiological characterization of traits related to salinity tolerance in an advanced backcross population of wheat
(2018-03-22)In large areas of the world wheat production is highly affected by soil salinity. Increasing the genetic variability of currently used wheat varieties is an efficient approach to overcome production losses and prevent food ... -
Vitamin D status and risk of anemia in patients with cardiovascular disease
(2018-03-26)Vitamin D deficiency and anemia are prevalent in patients with cardiovascular disease (CVD), and both are independent risk factors for increased morbidity and mortality. Epidemiological studies suggest an inverse association ... -
The impact of soil water distribution on root development and root water uptake of winter wheat
(2018-04-10)Root water uptake (RWU) is a key process in the root zone that determines water movement from the soil into roots and transport to the atmosphere via plant leaves. Different RWU models were developed with different assumptions ... -
Ethiopian Youth in Agriculture: Relative Deprivation, Well-being and Occupational Choices
(2018-03-05)Africa has the highest share of young people in the world relative to the total population, with the median age of the population under 25 years old, which is not expected to change in the coming decades. This high proportion ... -
Atmospheric refraction and turbulence in VLBI data analysis
(2018-03-06)The progress in further improving the quality of results derived by space-geodetic techniques observing in the radio frequency domain, such as Very Long Baseline Interferometry (VLBI) or Global Navigation Satellite Systems ... -
Investment in health within the agriculture, water, sanitation and hygiene nexus for rural households in Bangladesh
(2018-02-16)Water, sanitation and hygiene (WASH) related burden of disease is one of the most important aspects of human capital formation. As WASH is a system issue, it needs to be investigated with many other complementary factors ... -
Application of proximal sensing techniques for epidemiological investigations of Fusarium head blight in wheat under field and controlled conditions
(2018-02-13)Sensors can provide valuable insight into studying the physiological disorder due to plant pathogens. <em>Fusarium</em> head blight (FHB) influences the optical properties of wheat (<em>Triticum aestivum L.</em>) at canopy ... -
Interventionsstudie zur Rolle von Isoflavonen im Fettstoffwechsel gesunder postmenopausaler Frauen
(2018-03-19)In postmenopausalen Frauen (PMF) gehen hormonelle Veränderungen mit charakteristischen Wechseljahrsbeschwerden und Veränderungen der Körperfettverteilung sowie der Lipoprotein- und Serumlipidkonzentrationen einher und ... -
Occasional direct-seeding of grain legumes in Organic Agriculture in Germany and Brazil: fertilisation with P and S & weed control with natural herbicides
(2018-02-13)The aim of this work was to test strategies, which improve nutrient supply and weed control in occasional direct-seeded (DS) grain legumes in Organic Agriculture. The effect of intra-row fertilisation of rock phosphate ... -
Analyzing trade-offs between ecosystem services in multi-functional landscapes
(2018-03-06)The urgent need to preserve multiple ecosystem services is one of the key challenges in natural resource management globally. A management decision can cause undesired con- sequences when a decision is made without a ... -
Reactions between nitrite and soil organic matter and their role in nitrogen trace gas emissions and nitrogen retention in soil
(2018-01-22)As a key intermediate of both nitrification and denitrification, nitrite (NO<sub>2</sub><sup>-</sup>) is highly chemically reactive to soil organic matter (SOM), and it was proved previously that considerable amounts of ... -
Identification and characterization of a cystatin-like effector protein from beet cyst nematode Heterodera schachtii and its role in plant-nematode interaction
(2018-01-18)Sedentary cyst nematodes are of high economic interest as they can cause substantial yield losses in important crop plants. Due to their complex soil-based life cycle and severe restrictions on the application of nematicides ... -
Effects on Aerobic Processes at Silage Faces
(2018-01-31)In animal nutrition, one of the most important and indispensable requirements is high quality of feed. Especially the staple feed, which builds the basic feed for animals’ rations, has to fulfill high quality criteria. In ... -
MicroRNA-424/503 cluster involvement in regulation of bovine granulosa cell function and oocyte maturation
(2018-01-11)Several microRNA (miRNA) clusters are known to be differentially regulated during follicular development. Previously, it was reported that the miR-424/503 cluster was highly abundant in bovine granulosa cells (bGCs) of ...
