How do management practices and farm structure impact productive performances of dairy cattle in the province of Pichincha, Ecuador
(2020-11-11)
The combination of "ancestral knowledge" and modern agricultural techniques are increasingly used by Andes farmers, demonstrating its great importance as an ideal alternative to achieve international standards of productivity and sustainability. Pasture management has demonstrated its relevance in terms of milk volume and quality in farms located in the Ecuadorian highlands, showing a wide range of types of forage resource use, in its constant search for better animal yields from the occupancy rate. However, while ...

An approach to the use of technology in the cocoa-growing sector: a look from the producer
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-03-06)
A study was conducted to keep scientific record of the challenges and opportunities of the insertion of a mobile app for cocoa producers in the Colombia region as a prospective tool or strategy for technological transfer and appropriation into that sector. A survey with structured and semi-structured questions that pertained to cocoa producer men and women was conducted. The questions were related to the general conditions of their labour activities and were discriminant in the following categories: cocoa-grower ...

Are there gender differences in access to and demand for East Coast fever vaccine? Empirical evidence from rural smallholder dairy farmers in Kenya
(2020-11-03)
Women lag in the adoption of agricultural innovations compared to men, mainly due to gender inequalities in access to complementary inputs, capital, and knowledge/information. The Infection-and-Treatment-Method (ITM) is considered a safe and effective method of controlling East Coast fever. However, since its commercialisation in Kenya differences in demand for this vaccine among smallholder men and women dairy cattle keepers have not been assessed. Using a sample of 448 respondents, we used an Average-Treatment-Effect ...

Can calcium sprays alleviate jelly seed in mango fruits?
(2020-03-27)
Jelly seed is a major challenge in mango production leading to enormous losses in the value chain. This internal fruit disorder is characterised by disintegration of cells, consistency of jelly and broken cells. Calcium plays an important role in enhancing tissue stability and firmness thus reducing cell disintegration. A two-year field study was conducted in Embu County, Kenya using ‘Van Dyke’ cultivar trees of approximately 10 years old. The objective of the study was to investigate the effect of varied sources of ...

On the Impact of Texture and Grain Size on the Pseudoelastic Properties of Polycrystalline Fe–Ni–Co–Al–Ti Alloy
(2020-05-08)
The effects of thermomechanical treatments on crystallographic texture and grain size evolution and their impact on the pseudoelastic properties in Fe41–Ni28–Co17–Al11.5–Ti2.5 (at.%) were studied in the present paper. The results show that cold rolling leads to brass-type texture in this alloy, which is typical for low stacking fault energy materials. Thermal treatments up to 1300 °C were conducted and it is shown that the presence of β-phase helps to control grain growth. After the dissolution of the secondary phase ...

Characterisation of productivity and diseases affecting dairy goats in smallholder systems of Greater Thika Region, Kenya
(2020-11-18)
The current cross-sectional study aimed at characterising the productivity and diseases affecting dairy goats kept by smallholder farmers in three sub-counties in Thika Region, Kenya. Standard questionnaires were administered to 240 farmers through face-to-face interviews and the outputs were analysed using descriptive and inferential statistics. The farmers mainly kept crosses of Toggenburg (45.9 %), Kenyan Alpine (29.5 %) and Saanen (17.4 %) dairy goats. The average dairy goat flock size was 4.5 (range 1–23) and ...

Economic and financial returns of livestock agribusiness in high mountains of Nepal
(2020-11-25)
Development partners and donor agencies often target programs and projects in poverty stricken and vulnerable regions around the world. However, there is paucity on economic and financial analysis of such investments. This study contributes to the literature by assessing financial internal rate of return (FIRR) and economic internal rate of return (EIRR) of livestock agribusiness, a vital component of ‘High Mountain Agribusiness and Livelihood Improvement’ (HIMALI) project supported by the Asian Development Bank (ADB) ...

The influence of electric loading on crack paths in ferroelectrics
(2020-05-30)
Ferroelectric materials are widely used in our daily life and many advanced industrial products. The understanding of their fracture behavior has been in the focus of research for decades, since the success of their application requires reliability and durability. For ferroelectric fracture behavior, different fracture criteria have been proposed and the influence of various mechanical-electric loading combinations on crack propagation have been investigated. However, the crack path and the deflection of crack ...

Effect of Village Savings and Loan Associations on adoption of index-based crop insurance under limited liabilities
(2020-03-26)
A household survey and focus group discussions were conducted to quantify the general determinants of an index-based crop insurance adoption under limited liabilities in Burundi, and specifically the effect of existing Village Savings and Loan Associations (VSLAs). The survey sample comprised of 40 crop insurance adopters, 40 non-adopters and 40 drop-outs in Bukirasazi and Makebuko communes of Gitega province.
The results indicated that saving money (by VSLAs) for upcoming premium payments and regularly VSLA meetings ...

Warum man Weihnachten erfinden müsste ...
(2020)
„Wenn es Weihnachten nicht längst gäbe, so müsste man es erfinden.“ Dieses dem US-amerikanischen Autor und Journalisten Eric Sevareid zugeschriebene Zitat behauptet zu Recht die Ausnahmestellung von Weihnachten. Kein anderes Fest der christlichen Kulturtradition weckt so viel an Erwartungen, Gefühlen und Hoffnungen in den Menschen.
