Toroidal grating astigmatism of high-harmonics characterized by EUV Hartmann sensor
The beam transport of single high-order harmonics in a monochromator arrangement is studied. A toroidal grating combines spectral filtering and focusing in order to produce a small individual spot for each harmonic. Here, the effect of small deviations from perfect alignment is investigated. Experimentally, a Hartmann sensor monitors the EUV wavefront while the grating is subjected to an online alignment procedure. The obtained results are confirmed by a simple theoretical description employing optical matrix methods
Preparing community pharmacists for a role in mental health: An evaluation of accredited Australian pharmacy programs
Background: Australian community pharmacists are well placed to provide medication-related support and contribute to optimization of outcomes for mental health consumers and their caregivers. However, little is known about the actual competencies of community pharmacists to provide this care. To determine how graduates are being prepared to competently assist mental health consumers and their caregivers, an exploration of the mental health content of university pharmacy programs that set the foundation for pharmacists' professional roles is needed. Aim: To investigate the mental health content of accredited Australian pharmacy qualifying programs. Method: A review of publically available online profile information for accredited degree programs was conducted, and program coordinators from the 18 accredited pharmacy degree programs providers in Australia were surveyed. Results: Mental health education is embedded in core subjects such as pharmacology, pharmacotherapy, and pharmacy practice. Multiple options are employed to deliver mental health teaching, including lectures, workshops, and experiential learning. However, while education is intended to align with pharmacists' expected level of professional competencies, there is a lack of national standardized outcome-based competency criteria for new graduates and wide-ranging inter-program variations were evident. Conclusion: A lack of standardized content in pharmacy qualifying programs that underpin pharmacists' mental health knowledge and skills might result in variations to practice competencies. Further work is needed to determine how variations impact the way pharmacists deliver care to mental health consumers and their caregivers
Construction and model-based analysis of a promoter library for E. coli: an indispensable tool for metabolic engineering
<p>Abstract</p> <p>Background</p> <p>Nowadays, the focus in metabolic engineering research is shifting from massive overexpression and inactivation of genes towards the model-based fine tuning of gene expression. In this context, the construction of a library of synthetic promoters of <it>Escherichia coli </it>as a useful tool for fine tuning gene expression is discussed here.</p> <p>Results</p> <p>A degenerated oligonucleotide sequence that encodes consensus sequences for <it>E. coli </it>promoters separated by spacers of random sequences has been designed and synthesized. This 57 bp long sequence contains 24 conserved, 13 semi-conserved (W, R and D) and 20 random nucleotides. This mixture of DNA fragments was cloned into a promoter probing vector (pVIK165). The ligation mixtures were transformed into competent <it>E. coli </it>MA8 and the resulting clones were screened for GFP activity by measuring the relative fluorescence units; some clones produced high fluorescence intensity, others weak fluorescence intensity. The clones cover a range of promoter activities from 21.79 RFU/OD<sub>600 </sub>ml to 7606.83 RFU/OD<sub>600 </sub>ml. 57 promoters were sequenced and used for promoter analysis. The present results conclusively show that the postulates, which link promoter strength to anomalies in the -10 box and/or -35 box, and to the length of the spacer, are not generally valid. However, by applying Partial Least Squares regression, a model describing the promoter strength was built and validated.</p> <p>Conclusion</p> <p>For <it>Escherichia coli</it>, the promoter strength can not been linked to anomalies in the -10 box and/or -35 box, and to the length of the spacer. Also a probabilistic approach to relate the promoter sequence to its strength has some drawbacks. However, by applying Partial Least Squares regression, a good correlation was found between promoter sequence and promoter strength. This PLS model can be a useful tool to rationally design a suitable promoter in order to fine tune gene expression.</p
Performance Measurement of Zakat Utilization: The Effectiveness of Zakat Distribution
In this study, we will examine the performance of zakat. The background of the research is the zakat utilization program as one of the programs in the zakat intermediation role, performance must be assessed to see the sustainability of the program. One of them is the effectiveness of the zakat distribution program. The research method used is a case study of zakat programs (BAZNAS) in West Java area, with a descriptive analysis approach. Data collection techniques used were observation, in-depth interviews and documentation. The results of this study are expected to be an innovation that becomes a reference for zakat institution managers to assess the performance of zakat utilization by looking at the effectiveness of the zakat distribution program. Zakat distribution program at BAZNAS of West Java focuses on the economy, health, and education. BAZNAS of West Java is distributed for da’wah and the victims of natural disasters. Zakat utilization at BAZNAS of West Java covers the fields of economy, health, and education. In carrying out the role as a zakat distributor, BAZNAS of West Java still encounters obstacles that hinder the effectiveness of the zakat distribution program. Many measurements are used to assess the effectiveness of its role in zakat distribution, including the implementation of standard operating procedures (SOP).

Immunomodulation of the Tumor Microenvironment: Turn Foe Into Friend
Immunotherapy, where the patient's own immune system is exploited to eliminate tumor cells, has become one of the most prominent new cancer treatment options in the last decade. The main hurdle for classical cancer vaccines is the need to identify tumor- and patient specific antigens to include in the vaccine. Therefore, in situ vaccination represents an alternative and promising approach. This type of immunotherapy involves the direct intratumoral administration of different immunomodulatory agents and uses the tumor itself as the source of antigen. The ultimate aim is to convert an immunodormant tumor microenvironment into an immunostimulatory one, enabling the immune system to eradicate all tumor lesions in the body. In this review we will give an overview of different strategies, which can be exploited for the immunomodulation of the tumor microenvironment and their emerging role in the treatment of cancer patients
Emoto - visualising the online response to London 2012.
In recent years we have moved from data scarcity to data abundance. As a response, a variety of methods have been adopted in art, design, business, science and government to understand and communicate meaning in data through visual form. emoto (emoto2012.org) is one such project, it visualised the online audience response to a major global event, the London 2012 Olympic and Paralympic Games. emoto set out to both give expression to and augment online social phenomena, that are emergent and only recently made possible by access to huge real-time data streams. This report charts the development and release of the project, and positions it in relation to current debates on data and visualisation, for example, around the bias and accessibility of the data, and how knowledge practices are changing in an era of so-called 'big data.
