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 ...

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 ...

Kurzarbeit im Korsettt der Versicherungslogik: Es ist Zeit, die "Bazooka" neu zu justieren
(2021-06)
Ehre wem Ehre gebührt, aber Olaf Scholz hat die Kurzarbeit nicht erfunden, wie es ihm im Eifer des Wahlkampfs herausrutschte. Es besteht zwar kein Zweifel, dass er als Arbeitsminister in der Finanz- und Wirtschaftskrise 2008/09 dieses Instrument kreativ und effektiv nutzte, erfunden haben es aber die Badener:innen schon in der Tabakkrise 1909. Dabei diente dieses Instrument in Baden nicht nur als Brücke der fairen Einkommenssicherung, sondern auch als Brücke zu einem nachhaltigen Strukturwandel: Statt weiter am Anbau ...

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) ...

An investigation of the aspects affecting non-Muslim customers’ purchase intention of halal food products in Jakarta, Indonesia
(2021-05-25)
The international trade market of halal food products is huge and has become a fast-growing segment. People that consume food and beverage will also consider if it is good for health, well-being, nutrition, and physical fitness. Nowadays, halal products are requested by Muslim and non-Muslim customers due to safety and quality concern. Even though several studies have been conducted for Muslim customers, but there is a lack of data by foregoing studies which exploring non-Muslim customers about their intention in ...

Synthese von Ester- und Etherlipiden durch die GPAT/AGPAT-Proteinfamilie und Lipin in Dictyostelium
(2021-05-12)
The synthesis of glycerolipids starts with the acylation of lipid backbones. Two structurally different glycerolipids emerge in the cell: ether-lipids and ester-lipids. In the case of ether-lipids the first fatty acid is substituted with a fatty alcohol inside the peroxisome. By the characterization of the protein FARAT in this thesis, a key enzyme in etherlipid-synthesis was identified for D. discoideum. FARAT shows a peroxisomal localization and is in principle able to do two jobs. Firstly, it initiates the peroxisomal ...

Accelerating Entrepreneurial Decision-Making Through Hybrid Intelligence
(2020)
Purpose: Previous studies revealed that around 75 percent of all start-ups fail at an early stage. One main reason for this tremendous failure rate is that entrepreneurs are typically confronted with high levels of uncertainty about the viability of their proposed business idea. Following this argumentation, entrepreneurial decision-making can be defined as complex decision-making problem under both risk and uncertainty. While risk includes quantifiable probabilities, uncertainty describes situations where neither ...

What Do Coaches Actually Do? A Context-Sensitive Approach to Workplace Coaching
(2021)
Vor dem Hintergrund einer noch wenig fortgeschrittenen Forschung zu Wirkfaktoren von Coaching, zielt diese Dissertation darauf ab, die in neueren Forschungsarbeiten skizzierten Forschungslücken hinsichtlich Coach-Verhalten und Kontextfaktoren zu schließen. Um den Blickwinkel auf relevante Kontextfaktoren zu erweitern, liegt der Fokus auf dem Verhalten von Coaches in zwei verschiedenen Arten von Kontexten: dem Beginn von Coaching-Prozessen (d.h. der Eingangsdiagnostik) und Coaching für Gründer*innen.

Morphological and functional examination of neuropeptides in the circadian system of Rhyparobia maderae with special focus on myoinhibitory peptides
(2021)
Die circadiane Uhr terrestrischer Organismen erlaubt die Anpassung von Physiologie und Verhalten an 24 h Rhythmen der Umwelt wie beispielsweise den täglichen Licht-Dunkel-Wechsel. Rhyparobia maderae wurde als Organismus zur Forschung an der inneren Uhr etabliert. Die circadiane Uhr der Madeira Schabe ist die akzessorische Medulla (AME) im optischen Lobus, welche von etwa 240 Neuronen innerviert wird. Diese Neuronen exprimieren und kolokalisieren auffällig viele Neuropeptide, die als Neuromodulatoren/Neurotransmitter ...

Ferrocen-basierte N-heterocyclische Tetrylene mit tertiären Alkylsubstituenten an den Stickstoff-Atomen
(2020)
In 2009, our group published two stable N-heterocyclic carbenes (NHCs) with a 1,1'-ferrocenediyl backbone (fc), which formally exhibit a six-membered FeIIC2N2CII-heterocycle. The stabilization of the fcNHCs is favored by bulky N-substituents. So far neopentyl and 2-adamantyl have been used for this purpose - a bulky primary and secondary alkyl substituent. In contrast to other cyclic diaminocarbenes, the fcNHCs are capable of activating small molecules such as NH3 or CO. The reason for this remarkable ability is the ...
