An experiment was conducted to investigate the effects of dietary supplementation of Ziziphora (Thymyus valgaris), Oregano (Oreganum valgare) and Peppermint (Lamiaceae Mentha piperita) on performance [feed intake, weight gain and feed conversion ratio (FCR)] and carcass characterization of broiler chickens. 240 ROSS strain broiler chicks were selected and divided into 4 treatments and 3 replicates based on completely randomized design. The groups comprised group 1 or control (fed basal diet, without medicinal plant supplementation), group 2 (fed 1% Ziziphora, 0.5% Oregano and 0.5% Peppermint), group 3 (fed 1% Oregano, 0.5 Ziziphora and 0.5% Peppermint) and group 4 (fed 1% Peppermint, 0.5% Ziziphora and 0.5% Oregano). Significant effects of dietary medicinal plants mixture on performance and carcass quality were observed (P<0.05). The highest feed intake (163.53 g) was recorded for group 2, while the highest daily weight gain (166.53 g), best feed conversion ratio (FCR: 1.91), highest carcass yield (70.76% of body weight), lowest abdominal fat (2.34%) and lowest gastrointestinal weight (6.34%) were recorded for group 3, in comparison with other experimental groups. In conclusion, dietary supplementation of 2% from this combination of medicinal plants (1% Oregano, 0.5% Ziziphora and 0.5% Peppermint) caused performance and carcass quality improvement via more weight gain increase in carcass yield and then decreases abdominal fat deposition. © 2011 Academic Journals.

The goal of the present research paper is to study the effect of cash flow on investment levels in companies. 75 firms accepted in Tehran Stock Exchange were investigated for their performances during the years between 2004 and 2010. The year 2008 was assumed to be the index year. In this paper the effects of four variables related to operational cash flow, financial supply and investment on investments' levels were studied. These variables are operational incomes, operational profit, debt ratio, and change in tangible fixed assets. The results of the regression test showed that cash flow, previous operational incomes, operational profit, and the ratio of debts and tangible fixed assets have a positive and meaningful effect on investment levels in companies but the future operational income does not affect companies' investments.

Different methods have been presented to optimize the need to query processing optimization in databases. Reasons of these need increase the amount of data and the queries sent to the Database Management System. This article presents a multi agent system for heterogeneous distributed database by compiling two technologies of query processing optimization in database. This system is compatible of ordering adaptation and it is also flexible in adapting necessary changes as it progresses. In this system a new Algorithm based on modeling of users' long term requirements is used. In this system an Agent gathers data related to manner of users' usage from join in queries. Results of performances show that suggested Algorithm have high adaption ability with comparison to classic Algorithm. © 2010 IEEE.

In this paper, we demonstrate a compact and integrated optical spectrum analyzer (OSA) based on metal composite single nanoparticle. We present and analyze an OSA at nanoscale which is able to selected different frequency contents of the incident field and illustrate with corresponding different amplitudes and wavelengths on monitor. The spectrum analyzer is composed of a single metal nanocomposite particle, forming relatively tunable narrowband filter implemented by Electromagnetically Induced Transparency (EIT) that operates at different frequencies. The composite metal nanoparticle composed of plasmonic core-shell nanoparticle is used as a building block for this idea in our study. Also, the proposed idea can easily be integrated on optical chips. The present design is simple for realization using optical integrated circuits, and has high accuracy and compact. This new OSA is suitable for spectroscopy of molecular systems in a nanoscale pattern for increasing density of integration in integrated systems.

Innovation is considered as one of the reinforcing agents in organizations. Software engineering teams are composed of different people with different skills. These teams can make use of innovation. The aims of using innovation in these teams are of three types: competition in market; production of goods and general or other goals. This research attempts to examine different viewpoints and offer innovation as an opportunity in software teams. However, if not controlled, innovation can be a real challenge for these teams. This research try to answer the question that whether innovation is an opportunity or a challenge in software development. As the research indicates, innovation as an opportunity in software development teams was accepted and if controlled and managed correctly, it can bring about many advantages for the team and the organization. © 2013 Academic Journals Inc.
