Use Of Core Stabilization Exercise And Medical Exercise Therapy In The Treatment Of A Patient With Chronic Post Partum Low Back Pain: A Case Report
Low back pain and lumbar hyper-mobility are common during and after pregnancy. Chronic postpartum low back pain (LBP) can be difficult to manage. Core stabilization exercises (CSE) have been shown to improve function and reduce pain in patients with chronic LBP due to lumbar instability. Medical Exercise Therapy (MET) has shown good outcomes in reducing pain in patients with LBP but has not been thoroughly investigated in the treatment of chronic post partum LBP. There is limited research reporting the use of a combined treatment protocol utilizing CSE and MET in the treatment of chronic LBP in postpartum women. The purpose of this case report was to investigate a combined physical therapy treatment protocol of CSE and MET on a patient with chronic low back pain 2 years post-partum.https://dune.une.edu/pt_studcrposter/1079/thumbnail.jp
PURE ROTATIONAL STUDY OF CYANOPHENYLACETYLENE ()
The reaction of cyano radical with hydrocarbon chains and rings is thought to be important in the formation of complex nitriles, particularly in the formation of polycyclic aromatic hydrocarbons (PAHs).
Difficulties in studying these reactions arise from both the plethora of possible product channels, and gaps in our knowledge as to the key species in each pathway.
One reaction that has been studied in some detail is cyano radical with phenylacetylene.\footnote{Bennett et al., Phys. Chem. Chem. Phys. 12, 8737-8749 (2010)}
One of the products identified in this reaction is cyanophenylacetylene (3-Phenyl-2-propynenitrile, \ce{C6H5C3N}), the rotational spectrum of which has not been previously studied.
Motivated in part by the recent detection of benzonitrile in the ISM,\footnote{McGuire et al., Science 359, 202â205 (2018)} and the presence of large cyanopolyyne chains there,\footnote{Broten et al., ApJL 223, L105-L107 (1978)}, the pure rotational spectrum of \ce{C6H5C3N} has been investigated in the 8--18 GHz and 75--220 GHz regions.
We will present our results (experimental spectrum and rotational constants), and discuss the various methods we used in fitting the data.
The new data now allow a search for this species in the ISM
BUILDING A DATABASE FOR QCL PUMPED FAR-IR LASERS
Our collaborative team is developing new experimental set-ups based on heterodyne mixing of synchrotron radiation (extracted by the AILES beamline of SOLEIL) with various Local Oscillators (LOs).
In the sub-millimeter and THz regions (defined as 0.1--1 THz), LOs from electronic techniques are easy to implement through the use of multiplication chains.
However, it is more challenging to produce fixed LOs in the far-IR domain (1--6 THz).
The recent development of a new generation of molecular lasers pumped by 10 m QCLs\footnote{Pagies et al., APL Photonics 1 (2016)} allows us to generate many more far-IR frequencies than the previous approach which used CO lasers as a pump source.
The difficulty in this technique stems from selecting the proper far-IR transitions that both involve rotational states susceptible to lase and that are accessible with our 10 m QCL source.
We will present our program making use of HITRAN, JPL, CDMS, and ExoMol databases to produce lists of far-IR lasing frequencies
STRATEGIES FOR INTERPRETING TWO DIMENSIONAL MICROWAVE SPECTRA
Microwave spectroscopy can uniquely identify molecules because their rotational energy levels are sensitive to the three principal moments of inertia. However, a priori predictions of a molecule's structure have traditionally been required to enable efficient assignment of the rotational spectrum. Recently, automated microwave double resonance spectroscopy (AMDOR) has been employed to rapidly generate two dimensional spectra based on transitions that share a common rotational level, which may enable automated extraction of rotational constants without any prior estimates of molecular structure. Algorithms used to date for AMDOR have relied on making several initial assumptions about the nature of a subset of the linked transitions, followed by testing possible assignments by âbrute force.â In this talk, we will discuss new strategies for interpreting AMDOR spectra, using eugenol as a test case, as well as prospects for library-free, automated identification of the molecules in a volatile mixture
A rotational and vibrational investigation of phenylpropiolonitrile (CHCN)
The evidence for benzonitrile (CHCN}) in the starless cloud core
TMC-1 makes high-resolution studies of other aromatic nitriles and their
ring-chain derivatives especially timely. One such species is
phenylpropiolonitrile (3-phenyl-2-propynenitrile, CHCN), whose
spectroscopic characterization is reported here for the first time. The low
resolution (0.5 cm) vibrational spectrum of CHCN} has been
recorded at far- and mid-infrared wavelengths (50 - 3500 cm) using a
Fourier Transform interferometer, allowing for the assignment of band centers
of 14 fundamental vibrational bands. The pure rotational spectrum of the
species has been investigated using a chirped-pulse Fourier transform microwave
(FTMW) spectrometer (6 - 18 GHz), a cavity enhanced FTMW instrument (6 - 20
GHz), and a millimeter-wave one (75 - 100 GHz, 140 - 214 GHz). Through the
assignment of more than 6200 lines, accurate ground state spectroscopic
constants (rotational, centrifugal distortion up to octics, and nuclear
quadrupole hyperfine constants) have been derived from our measurements, with a
plausible prediction of the weaker bands through calculations. Interstellar
searches for this highly polar species can now be undertaken with confidence
since the astronomically most interesting radio lines have either been measured
or can be calculated to very high accuracy below 300 GHz.Comment: 7 figures, 4 tables. Accepted for publication in J. Mol. Spe
Orthopaedic Surgeon Density in West Virginia
Abstract
West Virginia (WV) has many healthcare disparities and access barriers. For bone and joint disorders, WV has some of the highest rates of musculoskeletal problems, including the highest reported rate of adult arthritis in the nation (36.2%). We hypothesized that WV has one of the lowest Orthopaedic surgeon densities in the country, which can negatively impact the delivery of musculoskeletal care. Using the WV Board of Medicine practitioner databank, the Veterans Administration practitioner data, and national Orthopaedic surgeon census data, we demonstrated a considerably low Orthopaedic surgeon density in WV (7.71/100,000 population versus the national average of 8.51/100,000 population) with 54% of our counties (n=30) having no Orthopaedic surgeons. This data is currently being used to further determine the appropriate allocation of resources to help improve access to specialized orthopaedic care for our state
Estimating dominant runoff modes across the conterminous United States
Effective natural resource planning depends on understanding the prevalence of runoff generating processes. Within a specific area of interest, this demands reproducible, straightforward information that can complement available local data and can orient and guide stakeholders with diverse training and backgrounds. To address this demand within the contiguous United States (CONUS), we characterized and mapped the predominance of two primary runoff generating processes: infiltrationâexcess and saturationâexcess runoff (IE vs. SE, respectively). Specifically, we constructed a gapâfilled grid of surficial saturated hydraulic conductivity using the Soil Survey Geographic and State Soil Geographic soils databases. We then compared surficial saturated hydraulic conductivity values with 1âhr rainfallâfrequency estimates across a range of return intervals derived from CONUSâscale random forest models. This assessment of the prevalence of IE versus SE runoff also incorporated a simple uncertainty analysis, as well as a case study of how the approach could be used to evaluate future alterations in runoff processes resulting from climate change. We found a low likelihood of IE runoff on undisturbed soils over much of CONUS for 1âhr storms with return intervals \u3c5 years. Conversely, IE runoff is most likely in the Central United States (i.e., Texas, Louisiana, Kansas, Missouri, Iowa, Nebraska, and Western South Dakota), and the relative predominance of runoff types is highly sensitive to the accuracy of the estimated soil properties. Leveraging publicly available data sets and reproducible workflows, our approach offers greater understanding of predominant runoff generating processes over a continental extent and expands the technical resources available to environmental planners, regulators, and modellers
