where Bn, n ≥ 0, denotes the nth Bernoulli number, and where σν(n) = ∑ d|n d ν . The latter two representations in (1.1) can be established by using the Lipschitz summation formula or Fourier analysis. For these and other basic properties of Eisenstein series, see, for example, R. A. Rankin’s text [41, Chap. 6]. In Ramanujan’s notation, the three most relevant Eisenstein series are defined for ...

Variegated plants provide a valuable tool for studying chloroplast biogenesis by allowing direct comparison between green and white/yellow sectors within the same leaf. While variegated plants are abundant in nature, the mechanism of leaf variegation remains largely unknown. Current studies are limited to a few mutants in model plant species, and are complicated by the potential for cross-conta...

motif is a literary device that is usually used to enrich a text. it has not only to do with any recurring element within a literary work but with the creation of certain effects on the reader. the contemporary iraqi poet, yahya samavi, has used motif not only as a decorative device but as a means to convey ideas dominant in his poetry. one of these dominant motives which reflect his life and m...

This Study addresses some of the poetry experiences that attracts attention. Due to mixing with arts such as cinema, which has always been approaching literature, especially poetry, from very beginning. Therefore, Qasida enjoys properties scenario stages can have a higher literary value, due fact there are many similarities between framework is processed by scriptwriter, and how sentences arran...

the current study examines contradictions in muhammad mahdi al-jawahiri’s political poetry. al-jawahiri led most of his life amidst the turmoil caused by the political events and developments that iraq has undergone through different periods beginning with the 1920 revolution led by religious leaders and ending with al-ba‘th party and saddam hussein. al-jawahiri has beencontradictory in his poe...

A significant role of zinc-binding motifs on metal mobility in Escherichia coli was explored using a chimeric metal-binding green fluorescent protein (GFP) as an intracellular zinc indicator. Investigation was initiated by co-transformation and co-expression of two chimeric genes encoding the chimeric GFP carrying hexahistidine (His6GFP) and the zinc-binding motif fused to outer membrane protei...

Two-component systems are major regulatory systems for bacterial adaptation to environmental changes. During the infectious cycle of Mycobacterium tuberculosis, adaptation to an intracellular environment is critical for multiplication and survival of the micro-organism within the host. The M. tuberculosis prrA gene, encoding the regulator of the two-component system PrrA-PrrB, has been shown to...

A two-step templated, ribosomal biosynthesis/printing method for the fabrication of protein microarrays for surface plasmon resonance imaging (SPRI) measurements is demonstrated. In the first step, a sixteen component microarray of proteins is created in microwells by cell free on chip protein synthesis; each microwell contains both an in vitro transcription and translation (IVTT) solution and ...

A new staining method was developed for the detection of inclusions of Chlamydia psittaci and Chlamydia trachomatis inclusions in cell cultures. Using a combination of methyl green and neutral red stains and washing at pH 5.0, inclusions were stained red while cell cytoplasm was pale pink and cell nuclei were pale green. The method was significantly better than Giemsa staining and comparable to...

BACKGROUND Over the last decade healthcare management and managers have increasingly been in focus in public debate. The purpose of the present study was to gain a deeper understanding of how prolonged, unfavorable media focus can influence both the individual as a person and his or her managerial practice in the healthcare organization. METHODS In-depth interviews (n = 49) with 24 managers a...
