Assessment of pond and integrated aquaculture (IAA) systems in six districts of Tanzania
(2021-06-04)
Integrated agriculture and aquaculture systems (IAA) are well known for their ability to improve the overall farm productivity and profitability. This is through recycling of on-farm resources, such as nutrient rich fish pond water and agriculture remains that would otherwise be considered as wastes. The present study explores the existing and potential IAA systems in Tanzania. It also examines management strategies and their influence on fish yield and the economic returns between IAA and non-IAA fish farming. The ...

Choice of savings instruments among rural women maize farmers: evidence from Uganda
(2021-05-25)
Households in developing countries employ a wide range of mechanisms for making cash and in-kind (goods and services) savings which are either formal or informal. Yet, literature on how choices about appropriate savings instruments are made remains scanty. We examine the patterns and choice of these saving instruments using household data from women farmers in eastern Uganda. In particular, the paper focuses on the choice between formal cash saving instruments like commercial banks, village savings and loans associations ...

Lokale Konzepte und Partikelverben in einem Modell der Sprachproduktion
(1998)
This article deals with semantically transparent particle verbs in German, which contain an incorporated local expression cognate with a local preposition. In contrast to expressions containing local prepositional phrases, the potential reference object of the incorporated local particle remains systematically unspecified. Regarding the data from a procedural vantage point, we argue that an adequate formulation of the underlying contextual/conceptual structure of particle verbs requires no referential specification ...

Microscale-Motivated Continuum Damage Simulations of Brittle Ceramics under Thermomechanical Loading
(2016-05-02)
Two approaches towards modeling damage in a brittle material caused by thermomechanical loading are presented.
Bothrelyonmicrocrack growth, in the first case in ahomogeneousmatrix, in the second one at grain boundaries.Two-scale simulations e.g. of thermal shocks applied to single-phase or layered structures are performed in connection with the finite element method. Damage and crack patterns are predicted just as quantities like residual strength or critical temperature jumps.

Nutrient digestibility, nitrogen balance and rumen fermentation parameters of West African dwarf goats offered treated maize stover supplemented with Gmelina arborea
(2021-05-20)
A large portion of agricultural crop residues are potential feed resources for ruminants in the tropics. This study therefore, investigated the intake, nutrient digestibility, nitrogen utilisation and rumen fermentation parameters of West African dwarf goats (WAD) fed treated and untreated maize stover supplemented with Gmelina arborea. Twenty male WAD goats (11.50 ± 0.45 kg body weight) were randomly allotted into four treatments with five animals each. Untreated maize stover (MS), urea treated maize stover (UT), ...

Projektionsfläche Hildegard
(2012)
Im Oktober diesen Jahres soll Hildegard von Bingen zur Kirchenlehrerin erhoben werden. Dies hat der als Vatikanexperte geltende Journalist Andrea Tornielli im Dezember 2011 in der italienischen Zeitung „La Stampa“ angekündigt. Ein wichtiger Schritt dorthin ist bereits vollzogen. Hildegard von Bingen wäre die vierte Frau, die den Ehrentitel der Kirchenlehrerin erhält. Am 10. Mai hat Benedikt XVI. Hildegard von Bingen offiziell in das Verzeichnis der Heiligen aufgenommen und die bisher nur im deutschsprachigen Raum ...

Growth performance and immunological response of African Catfish (Clarias gariepinus) juveniles reared in biofloc system
(2021-06-08)
This study was conducted to examine the growth and immune performance of catfish (Clarias gariepinus) juveniles cultured in a biofloc fish farming system. To achieve this, 900 C. gariepinus juveniles (9.0 ± 0.23 g) were cultured in an intensive zero water exchange biofloc system for 72 days in 9 separate tanks (2 m3 each) aerated by an air blower, after which growth assessment of fish was conducted. The trial consisted of three treatments in triplicates, a control without carbon source addition, and two biofloc ...

A review of the literature on gender and chemical fertiliser use in maize production in sub-Saharan Africa
(2021-05-25)
Are there differences in men’s and women’s access to and use of fertiliser in sub-Saharan Africa? This article explores the issue through a systematic review of the extant literature on gender and fertiliser use in maize production. The findings show that indeed a gender gap in the use of fertiliser exists. More than a decade after the World Bank identified a gender gap in fertiliser use, there are no systematic national or global data sets comparing fertiliser use by gender. While farm input subsidies can improve ...

Incorporation of dried goat rumen contents in layer diets improves egg yolk colour and acceptability of eggs
(2021-06-07)
The use of dried goat rumen content (DGRC) as a partial replacement for fish meal in layer diets was investigated. A total of 90 H&N Brown Nick layer chickens were offered diets in which DGRC were incorporated at 0, 5 and 10% levels. Iso-caloric and nitrogenous diets were formulated to meet the recommended nutritional requirements for laying hens. Experimental birds were assigned to 9 cages (10 birds/cage) and experimental diets offered in a completely randomized design (CRD) with three replications. Data was collected ...

Do We Pronounce Quotation? An Analysis of Name-informing and Non-name-informing Contexts
(2019-12-23)
Quotation marks are a tool to refer to the linguistic form of an expression. For instance, in cases of so-called pure quotation as in “Hanover” has three syllables, they point to the syllabic characteristics of the name of the town of Hanover. Cases of this nature differ from sentences like Hanover is a town in New Hampshire, in which Hanover is used denotationally and, thus, refers to the town of Hanover itself. Apart from quotation marks, other means such as italics, bold, capitalization, or air quotes represent ...
