SARS-CoV-2 wastewater monitoring in rural and small metropolitan communities in Central Michigan.

Central Michigan University (CMU) participated in a state-wide SARS-CoV-2 wastewater monitoring program throughout the 2021-2022 academic year. Wastewater samples were collected weekly from ten on-campus sites and nine off-campus wastewater treatment plants servicing small metropolitan and rural communities. SARS-CoV-2 genome copies were quantified using droplet digital PCR.

From Grieving to Giving: When Former Bereavement Campers Return as Volunteers.

This study examines the lived experiences of bereavement camp participants who return to camp as volunteer counselors. Participants in the study were eight bereavement camp counselors who once attended camp as bereaved participants. Using a qualitative case study design, the participants were interviewed by the researchers, and data collected from these interviews were analyzed using the constant comparison method.

Probing the effect of polymer molecular weight on penetration into the wood cell wall using polyethylenimine (PEI) as a model compound.

Decking is one of the largest applications for the treated wood market. The most challenging property to obtain for treated wood is dimensional stability, which can be achieved, in part, by cell wall bulking, cell wall polymer crosslinking and removal of hygroscopic components in the cell wall. A commonly accepted key requirement is for the actives to infuse through the cell wall, which has a microporosity of ∼5-13 nm.

Benefits transfer and the aquatic environment: An investigation into the context of fish passage improvement.

We present findings from a choice experiment investigating improvements in the aquatic environment from mitigation of barriers to fish passage. Implemented at a local and national level, results reveal positive preferences for increased numbers of fish species as well as fish abundance. In addition, we examine if in this case the willingness to pay estimates are suitable for direct transfer between national and local settings.

The Impact of Death Education on Fear of Death and Death Anxiety Among Human Services Students.

Human services professionals will undoubtedly work with the dying and bereaved populations at one time or other. Yet, they are poorly prepared to do so since death education, that is, lessons about the human and emotional aspects of death, its implications, and subsequent bereavement issues, is often not part of their curriculum. This nonequivalent comparison group study (N = 86) examined death fear and death anxiety among human services students before and after receiving death education using the Multidimensional Fear of Death Scale.

Child maltreatment histories among female inmates reporting inmate on inmate sexual victimization in prison: the mediating role of emotion dysregulation.

Despite data indicating that child maltreatment (CM) in various forms is associated with adult sexual victimization among community women, few studies have explicitly explored how types of CM might relate to prison sexual victimization. Because little is known about how CM might give rise to prison sexual victimization, the present study also examined emotion dysregulation emanating from early abuse experiences as a potential mediator in the link between early CM and inmate-on-inmate prison sexual victimization. Approximately 168 incarcerated women completed self-report inventories assessing various types of childhood maltreatment, emotion dysregulation, and coerced or forced sexual experiences in prison.

Species identification in cell culture: a two-pronged molecular approach.

Species identification of cell lines and detection of cross-contamination are crucial for scientific research accuracy and reproducibility. Whereas short tandem repeat profiling offers a solution for a limited number of species, primarily human and mouse, the standard method for species identification of cell lines is enzyme polymorphism. Isoezymology, however, has its own drawbacks; it is cumbersome and the data interpretation is often difficult.

Static and dynamic novelty detection methods for jet engine health monitoring.

Novelty detection requires models of normality to be learnt from training data known to be normal. The first model considered in this paper is a static model trained to detect novel events associated with changes in the vibration spectra recorded from a jet engine. We describe how the distribution of energy across the harmonics of a rotating shaft can be learnt by a support vector machine model of normality.

Rearrest and linkage to mental health services among clients of the Clark County mental health court program.

Objective: This study examined rearrest and linkage to mental health services among 368 misdemeanants with severe and persistent mental illness who were served by the Clark County Mental Health Court (MHC). This court, established in April 2000, is based on the concepts of therapeutic jurisprudence. This study addressed the following questions about the effectiveness of the Clark County MHC: Did MHC clients receive more comprehensive mental health services? Did the MHC successfully reduce recidivism? Were there any client or program characteristics associated with recidivism?

Methods: A secondary analysis of use of mental health services and jail data for the MHC clients enrolled from April 2000 through April 2003 was conducted.

Lessons learned in preparing to receive large numbers of contaminated individuals.

Traditionally, medical radiation emergency plans have provided for the receipt and care of a limited number of individuals, usually no more than two or three at any given time. Large numbers of contaminated, uninjured individuals cannot be effectively handled in the emergency departments (EDs) of hospitals as they present a risk of forcing the ED to close because of contamination and they divert ED personnel away from patients needing medical attention. Alternative locations and plans for handling large numbers of contaminated but otherwise uninjured patients must be considered.

Obesity-related differential gene expression in the visceral adipose tissue.

Background: This study investigates the expression patterns in human adipose tissue, and identifies genes that may be involved in the abnormal energy homeostasis.

Methods: Subjects were prospectively recruited from morbidly obese patients undergoing bariatric surgery and from non-obese organ donors. Extensive clinical data and visceral fat specimens were obtained from each subject at the time of surgery.

Recent experiences with shielding a PET/CT facility.

Since the photon energy of positron emitting radionuclides is significantly higher than the maximum kVp of diagnostic x rays, designing a shielding plan for a PET/CT imaging facility requires careful consideration of future workloads and potential occupancy of surrounding spaces. The shielding calculations can be done by hand or with the aid of available software. In calculating the shielding, specific considerations arise.

Potential Dose to Nuclear Medicine Technologists from 99mTc-DTPA Aerosol Lung Studies.

Air sampling performed during 190 Tc-labeled DTPA aerosol lung ventilation studies indicated that the maximum airborne concentration to which the nuclear medicine technologists might be exposed was 7.1 × 10 Bq mL (1.9 × 10 μCi mL).

Potential dose to nuclear medicine technologists from 99mTc-DTPA aerosol lung studies.

Air sampling performed during 190 Tc-labeled DTPA aerosol lung ventilation studies indicated that the maximum airborne concentration to which the nuclear medicine technologists might be exposed was 7.1 x 10(-1) Bq mL(-1) (1.9 x 10(-5) microCi mL(-1)).

A practical and scaleable synthesis of A-224817.0, a novel nonsteroidal ligand for the glucocorticoid receptor.

A practical and scaleable synthesis of a novel nonsteroidal ligand for the glucocorticoid receptor A-224817.0 1A is described. The synthesis proceeds in seven steps starting from 1,3-dimethoxybenzene.

Asymmetric synthesis of A-240610.0 via a new atropselective approach for axially chiral biaryls with chirality transfer.

A new approach for atropselective preparation of axially chiral biaryl was developed. This process proceeded through a chirality transfer from a stereogenic center of a secondary alcohol to the stereogenic axis via regioselective intramolecular silyl group migration. This methodology allowed for the preparation of a single atropisomer 2 in good yield (85%) with high diastereoselectivity (99:1), which subsequently led to the successful development of an efficient asymmetric synthesis of A-240610.
