On Scale Invariance and Anomalies in Quantum Mechanics

We re-consider the quantum mechanics of scale invariant potentials in two dimensions. The breaking of scale invariance by quantum effects is analyzed by the explicit evaluation of the phase shift and the self-adjoint extension method. We argue that the breaking of scale invariance reported in the literature for the $\delta$(r) potential, is an example of explicit and not an anomaly or quantum mechanical symmetry breaking.Comment: 15 pp in latex, no figure

Assessing the Level of Effectiveness of Marketing Activities of HEIs in the National Capital Region

Higher Education Institutions in the Philippines, just as any business institutions, conduct marketing activities to ensure the thriving admission and retention of students. This paper ascertained the effectiveness of the marketing activities used by selected HEIs in the National Capital Region through the “Four P’s of Marketing”. Results of the study can be used as references by HEIs in updating their marketing activities. Keywords: Marketing Activities, Four Ps of Marketing, Higher Education Institutio

The Promotion of Safety and Quality in Fall Prevention

Falls in a hospital setting are considered one of the most frequent, preventable adverse events that need to be addressed through the creation of safer environments. Nurses play a key element in the prevention and management of injuries related to falls. The focus question for this quality improvement initiative (QII) was whether an evidence-based QII program could reduce falls in the inpatient population. The objective of the project was to improve the practices related to fall prevention to reduce the number of inpatients falls. The change model of Kotter and the Preventing Falls in Hospitals: A Toolkit for Improving Quality of Care were used to implement the QII. The prevalence of falls from 1 month before the start of the project was compared to 1 month after the implementation of the falls program. The nurses were taught about the evidence-based interventions, the intentional hourly rounds, and the patients’ educations as well as administered the Fall Knowledge Test (Tool 2E) pre- and postimplementation. The interventions were implemented and the findings of the prevalence 3 months later show a significant decrease in the number of falls with 0 cases reported in November and December. Compared to the previous analysis, 53% (n = 8) of nurses recognized that meeting patients’ toileting needs decreases the risk for falls versus the pre-implementation result of 0% recognizing this action. The findings reinforce that a change in staff awareness was achieved, and the decrease in the incidence of falls reinforces the effectiveness of intentional hourly rounds and patient education. The results of this project may influence nursing administrators and other leaders to increase the application of fall prevention policies. The findings of this project promote a positive social change because the falls were reduced through the implementation of evidence-based interventions

Новий погляд на проблему української бідності

Статья посвящена формированию нового взгляда на проблему украинской бедности через призму современных социально-экономических реалий в Украине и в мировом сообществе. В роботе рассматриваются различные определения бедности по монетарным и немонетарным признакам и их пригодность для оценки ситуации в Украине.The article is devoted to forming of the new look to the problem of Ukrainian poverty through the prism of modern socio-economic realities in Ukraine and in the world. Different criteria of poverty determination by monetary and nonmonetary signs and their fitness to the estimation of situation in Ukraine are examined

Nanostructural differences in pectic polymers isolated from strawberry fruits with low expression levels of pectate lyase or polygalacturonase genes

Our research group has obtained transgenic strawberry plants expressing antisense sequences of either a pectate lyase (APEL lines) [1] or a polygalacturonase gene (APG lines) [2]. Both genes encode ripening-specific endo-pectinases with a common target, deesterified homogalacturonans, but each enzyme act by a different mechanism and pH range. Ripe fruits from both transgenic genotypes were significantly firmer than control, being APG fruits on average 25% firmer than APEL fruits. Cell wall analysis of both transgenic genotypes indicated that pectin fractions extracted with CDTA and sodium carbonate were significantly modified in transgenic fruits [2,3]. To gain insight in the role of these pectinases in pectin disassembly during ripening, CDTA and Na2CO3 pectins have been analyzed by atomic force microscopy (AFM). APEL and APG CDTA pectins had similar contour lengths but both were significantly longer than control. Similarly, APG carbonate chains were longer than control, showing APEL carbonate chains an intermediate length. Furthermore, transgenic pectins displayed a more complex branching pattern and a higher number of micellar aggregates, especially in the sodium carbonate fractions of APG samples. Acid hydrolysis of carbonate pectins reduced the number of micellar aggregates. AFM analyses confirm that the inhibition of both pectinases reduces pectin disassembly, and also suggest that each pectinase acts on specific pectin domains. Particularly, polygalacturonase silencing induces more significant pectin modifications, nicely correlated with the firmer phenotype of APG fruits, than the down-regulation of pectate lyase

A Novel Reporter Mouse Uncovers Endogenous Brn3b Expression.

Brn3b (Pou4f2) is a class-4 POU domain transcription factor known to play central roles in the development of different neuronal populations of the Central Nervous System, including retinal ganglion cells (RGCs), the neurons that connect the retina with the visual centers of the brain. Here, we have used CRISPR-based genetic engineering to generate a Brn3b-mCherry reporter mouse without altering the endogenous expression of Brn3b. In our mouse line, mCherry faithfully recapitulates normal Brn3b expression in the retina, the optic tracts, the midbrain tectum, and the trigeminal ganglia. The high sensitivity of mCherry also revealed novel expression of Brn3b in the neuroectodermal cells of the optic stalk during early stages of eye development. Importantly, the fluorescent intensity of Brn3b-mCherry in our reporter mice allows for noninvasive live imaging of RGCs using Scanning Laser Ophthalmoscopy (SLO), providing a novel tool for longitudinal monitoring of RGCs
