In ocean exploration and other maritime engineering, UAN (Underwater Acoustic Networks) is bound to play more important roles. Thinking of the serious environment UAN operates, safety and security must be guaranteed first. Among the possible attacks against UAN, DoS (Denial of Service) is a class of commonly-used methods. The basic procedures of different DoS attacks are analyzed and some of th...

Greenhouse studies were conducted in 2006 to evaluate the effects of urea ammonium nitrate (UAN) solution on bispyribac and penoxsulam efficacy on barnyardgrass and hemp sesbania. Bispyribac and penoxsulam treatments containing an adjuvant and UAN significantly reduced barnyardgrass biomass over most treatments without UAN. Urea ammonium nitrate did not increase hemp sesbania biomass reduction,...

There is an increasing requirement of the application of Underwater Acoustic Network (UAN) both in many fields. In the commercial applications, terrorists may carry through destroy activities; while in the military applications, even it is an inevitable activity to degrade the adversary UAN. Thus it can be seen that security measures must be integrated into UAN. This paper tries to do some effo...

Laboratory incubations of four broiler litter (BL) samples at 30°C were performed to investigate the effect of water content on the decay of uric acid nitrogen (UAN) and xanthine nitrogen (XN). UAN and XN concentrations increased in all samples during a period of 1 to 8 d before declining for the remaining 30 d. The increases may be the result of guanine and adenine catabolism. The slopes of li...

In this paper we define a translation from the User Action Notation (UAN) to the process algebra Communicating Sequential Processes (CSP). UAN is an informal notation, used for task modeling and design. Translating a UAN task description to CSP provides a basis for rigorous development of an interactive system. The resulting CSP description is a suitable abstract starting point for development,...

Spring application of post-emergence (POST) broadleaf herbicides in a urea ammonium nitrate (UAN) as the carrier may provide winter wheat growers with a one-pass option for weed control and nitrogen application. Winter wheat tolerance to bromoxynil/MCPA, dichlorprop/2,4-D, thifensulfuron/tribenuron + MCPA amine or pyrasulfotole/bromoxynil applied using 28% UAN at various carrier volumes (0, 100...

PURPOSE To examine the distribution of encapsulated nerve endings called mechanoreceptors in the human distal interphalangeal (DIP) joint and surrounding structures. METHODS We processed 12 right index finger DIP joints and surrounding structures from fresh cadavers for immunohistochemistry of the anti-protein gene product 9.5 (PGP9.5) and silver staining to detect encapsulated nerve endings....

A nitrogen (N) source comparison study was conducted to further evaluate the effects of inorganic N source and placement on growing-season and non-crop period soil nitrous oxide (NO). Commercially available controlled-release N fertilizers were evaluated for their potential to reduce NO emissions from a clay loam soil compared with conventionally used granular urea and urea-ammonium nitrate (UA...

In this note, we study monodromies of algebraic connections on the trivial vector bundle. We prove that on a smooth complex affine curve, any monodromy arises as the underlying local system of an algebraic connection on the trivial bundle. We give a generalization of this for rank one monodromies in higher dimension. Monodromies des connexions algébriques sur le fibré trivial Résumé. Dans cette...

There is great concern worldwide about air and water pollution arising from N-fertilizer. Considering the expansion of agriculture and fertilization practices in Argentina, the objective of this study was to determine the effect of Nfertilizers on soil N dynamics and then relationship with nitrate concentration in aquifers. Soil samples were taken during a maize crop cycle in two agricultural f...
