Development of \u3ci\u3eOrius Insidiosus\u3c/i\u3e (Hemiptera: Anthocoridae) in Relation to Temperature

A developmental threshold of lO.3°C and a thermal constant of 307 day-degrees C were estimated for a Wisconsin population of Orius insidiosus (Say) (Hemiptera: Anthocoridae) by rearing eggs and nymphs at various constant temperatures

Archeological Excavations in the Courtyard of Castillo de San Marcos, St. Augustine, Florida

The recorded history of the fortifications at St. Augustine, Florida, begins on the day the Spaniards, under Don Pedro Menendez de Aviles, landed at the Timucua Indian village of Seloy in the late summer of 1565. A large Indian communal house was turned over to the newcomers, who immediately set to work throwing up earthworks around the aboriginal structure

Monte Carlo Simulation of Lyman Alpha Scattering and Application to Damped Lyman Alpha Systems

A Monte Carlo code to solve the transfer of Lyman alpha (Lya) photons is developed, which can predict the Lya image and two-dimensional Lya spectra of a hydrogen cloud with any given geometry, Lya emissivity, neutral hydrogen density distribution, and bulk velocity field. We apply the code to several simple cases of a uniform cloud to show how the Lya image and emitted line spectrum are affected by the column density, internal velocity gradients, and emissivity distribution. We then apply the code to two models for damped Lya absorption systems: a spherical, static, isothermal cloud, and a flattened, axially symmetric, rotating cloud. If the emission is due to fluorescence of the external background radiation, the Lya image should have a core corresponding to the region where hydrogen is self-shielded. The emission line profile has the characteristic double peak with a deep central trough. We show how rotation of the cloud causes the two peaks to shift in wavelength as the slit is perpendicular to the rotation axis, and how the relative amplitude of the two peaks is changed. In reality, damped Lya systems are likely to have a clumpy gas distribution with turbulent velocity fields, which should smooth the line emission profile, but should still leave the rotation signature of the wavelength shift across the system.Comment: 19 pages, 17 eps figures. One panel is added in Fig.1 to show the recoil effect. Revisions are made in response to the referee's comments. Accepted for publication in Ap

Standards, Harmonization and Cultural Differences: Examining the Implementation of a European Stem Cell Clinical Trial

This is the author accepted manuscript. The final version is available from Taylor & Francis via the DOI in this record.A complex set of European regulations aims to facilitate regenerative medicine, harmonizing good clinical and manufacturing standards and streamlining ethical approval procedures. The sociology of standardization has elaborated some of the effects of regulation but little is known about how such implementation works in practice across institutions and countries in regenerative medicine. The effects of transnational harmonization of clinical trial conduct are complex. A long-term ethnographic study alongside a multinational clinical trial finds a range of obstacles. Harmonization standardizes at one level, but implementing the standards brings to the fore new layers of difference between countries. Europe-wide harmonization of regulations currently sdisadvantages low-cost clinician-lead research in comparison to industry-sponsored clinical trials. Moreover, harmonized standards must be aligned with the cultural variations in everyday practice across European countries. Each clinical team must find its own way of bridging harmonized compulsory practice with how things are done where they are, respecting expectations from both patients and the local hospital ethics committee. Established ways of working must further be adapted to a range of institutional and cultural conventions that affect the clinical trial such as insurance practices and understandings of patient autonomy. An additional finding is that the specific practical roles of team members in the trial affect their evaluation of the importance of these challenges. Our findings lead to conclusions of wider significance for the sociology of standards concerning how regulation works and for medical sociology about how trial funding and research directions in stem cell medicine intersect.The BAMI Project is partially funded by the European Commission under the 7th Framework Programme (Grant agreement number 278967)

Triple-Pomeron Matrix Model for Dispersive Corrections to Nucleon-Nucleus Total Cross Section

Dispersive corrections to the total cross section for high-energy scattering from a heavy nucleus are calculated using a matrix model, based on the triple-Pomeron behavior of diffractive scattering from a single nucleon, for the cross section operator connecting different states of the projectile nucleon . Energy-dependent effects due to the decrease in longitudinal momentum transfers and the opening of more channels with increasing energy are included. The three leading terms in an expansion in the number of inelastic transitions are evaluated and compared to exact results for the model in the uniform nuclear density approximation for the the scattering of nucleons from Pb^{208} for laboratory momenta ranging from 50 to 200 GeV/c.Comment: 16 pages, 2 figures, RevTex

The North American Spa Industry: An Examination of Emergent Trends

The spa industry is rapidly growing, both in North America and around the globe. However, hospitality and tourism professionals seem to be surprised and unprepared of the impressive evolution. The authors report of the North American spa industry’s current practices and emergent trends that are likely to prove significant for spa stakeholders and educators in this growing field of inquiry

Electromagnetic multipole theory for optical nanomaterials

Optical properties of natural or designed materials are determined by the electromagnetic multipole moments that light can excite in the constituent particles. In this work we present an approach to calculate the multipole excitations in arbitrary arrays of nanoscatterers in a dielectric host medium. We introduce a simple and illustrative multipole decomposition of the electric currents excited in the scatterers and link this decomposition to the classical multipole expansion of the scattered field. In particular, we find that completely different multipoles can produce identical scattered fields. The presented multipole theory can be used as a basis for the design and characterization of optical nanomaterials

A simple method for detection of mitochondrial DNA polymorphisms

Polymorphisms were identified in mtDNA of Heterobasidion annosum by digesting total genomic DNA with HaeIII, CfoI, or MspI, which recognize the restriction sites GGCC, GCGC, and CCGG, respectively. Most DNA was digested to fragments of less than 2 kb, while AT-rich fragments of 1.7 to 17 kb stood out as bands of uniform intensity after ethidium bromide staining. These fragments hybridized to mtDNA probes and were inherited in a uniparental fashion

Steroid-Responsive Encephalopathy Associated with Autoimmune Thyroiditis Presenting as Confusion, Dysphasia, and Myoclonus

Steroid response encephalopathy associated with autoimmune thyroiditis (SREAT), or Hashimoto's encephalopathy, is a rare disorder believed to be immune-mediated. It is most often characterized by a subacute onset of confusion with altered level of consciousness, seizures, and myoclonus. We describe the case of a 48-year-old gentleman who presented with confusion and dysphasia. Specific clinical features and laboratory results led to a diagnosis of Hashimoto's encephalopathy. This case highlights the core features of this condition and the potential for complete response to steroid therapy
