Arizona aquaculture production in 2000 was 680 metric tons. Finfish including tilapia, bass, trout and catfish accounted for 590 metric tons, while other culture organisms, primarily marine shrimp rounded out production. The continued success of the aquaculture industry in Arizona is dependent on the success of individual farms. By increasing the chances of success through the proper selection ...

Smallholding in the cocoa sector has been seen as a hindrance to production and productivity growth due to the ageing of the cocoa farmers, limited access to credit, low level of education and low adoptability of innovations. In order to curb this, policy makers have resorted to implementing policy instruments that encourage the extension of small rural farms into larger farms, thereby undermin...

Salmonid farming in Ireland is mostly organic, which implies limited disease treatment options. This highlights the importance of biosecurity for preventing the introduction and spread of infectious agents. Similarly, the effect of local network properties on infection spread processes has rarely been evaluated. In this paper, we characterized the biosecurity of salmonid farms in Ireland using ...

let $a$ be an abelian topological group and $b$ a trivial topological $a$-module. in this paper we define the second bilinear cohomology with a trivial coefficient. we show that every abelian group can be embedded in a central extension of abelian groups with bilinear cocycle. also we show that in the category of locally compact abelian groups a central extension with a continuous section can b...

Background and aims: Visit quality is a crucial component of patient-physician interaction that its inadequacy can negatively influence the diagnosis and treatment efficiency. The waiting time and visit length are important determinants of quality in the outpatient care setting. Thus, the aim of this study was to determine waiting time and visit length and to compare them befor...

artificial insemination (ai) is an important technique for breeding that has been extensively used in dairy farming worldwide. however, it has not been fully adopted in iran's dairy farms, especially in ardabil province. the main objective of this research was to study factors affecting adoption of ai in dairy farms of ardabil province. in order to predict the adoption of ai, technology ad...

background and aims: visit quality is a crucial component of patient-physician interaction that its inadequacy can negatively influence the diagnosis and treatment efficiency. the waiting time and visit length are important determinants of quality in the outpatient care setting. thus, the aim of this study was to determine waiting time and visit length and to compare them before implementation ...

in recent decades, large investments have been made to introduce soil conservation methods, but most of these efforts have had limited success in achieving the goals. as a result, attempt to identify the factors deterring or promoting adoption of soil conservation practices is important. therefore, this study aimed to investigate factors affecting adoption of soil conservation practices by rain...
