background and objectives:  haplophyllum canaliculatum isan endemicand endangerediranian plant from rutaceae family. the object of this work was to study the volatile production in established shoot and callus cultures of haplophyllum canaliculatum as well as isolation, identification and sequencing of 18s rrna gene from callus culture. methods: shoot and callus cultures of h. canaliculatum wer...

Effects of relative shoot height and irradiance on shoot and leaf properties of Quercus serrata Thunb. saplings growing in the understory and in gaps were investigated. Photosynthetic photon flux (PPF) at the location of the shoot relative to that in the open (relative PPF; rPPF) and the height of the shoot base relative to tree height (relative height; rHeight) were measured for all current-ye...

considering great medicinal value of hyssopus officinalis l. and possibility of its mass production through in vitro culture, two individual experiments was conducted. effect of various concentrations (0, 2.2, 4.4 and 11 µmol) of tdz and bap in combination with 1 µmol of iaa on direct regeneration from nodal explants were assessed. significant difference between treatments was observed (p≤ 0.01...

Reports of how different countries are responding to the need to develop more integrated health and social care services for older adults can provide useful lessons for other health systems. However an understanding of how the wider structural, political, economic and cultural context affects implementation of these models of care is essential when considering the potential for models to be sca...

Decreasing the number of adverse drug events requires a combination of clinical work-flow transformation and selective technology implementation.

In Germany and Turkey they viewed scenes that were particularly distressing. On the runway stood a German (or Turkish) quick-reaction alert airplane loaded with nuclear weapons and with a foreign pilot in the cockpit. The airplane was ready to take off at the earliest warning, and the nuclear weapons were fully operational. The only evidence of U.S. control was a lonely 18-year-old sentry armed...

One of the key problems of recent years has been the divide between theoretical work in agent-based systems and its practical complement which have, to a large extent, developed along different paths. The Paradigma implementation framework has been designed with the aim of narrowing this gap. It relies on an extensive formal agent framework implemented using recent advances in Java technology. ...

There are great expectations regarding the potential contribution of integrated care interventions to improved outcomes, but so far the evidence is mixed. In this dissertation, we focussed on why, when and how some integrated care interventions contribute to improved outcomes, while others do not. To this purpose, we developed the COMIC Model for studying the Context, Outcomes and Mechanisms of...

The uptake and metabolism of the cytokinin benzyl adenine (BA) was compared in two lines of Petunia hybrida Vilm. differing in their shoot organogenic response. Leaf transfer experiments using shoot induction medium containing 4.4 micromolar BA showed that leaf explants from petunia line St40 required a shoot induction period of 6 to 10 days for commitment to shoot organogenesis; whereas leaf e...

Abstract: This paper proposes an improved pulse-width modulation (PWM) strategy to reduce the capacitor voltage ripple in Z-source wind energy conversion system. In order to make sure that Z-source capacitor voltage has symmetrical maximum and minimum amplitudes in each active state, the shoot-through time is divided into six unequal parts. According to the active state and zero state, the shoo...
