Hydrogenolysis and dehydrogenation of propane were studied over model nickel–gold catalysts. The supported model Ni–Au catalysts were prepared by depositing Ni and Au onto a planar silica film. Infrared reflection absorption spectroscopic data showed that isolated Ni sites appeared and became dominant on the surface with the addition of Au to Ni. For the conversion of propane in the presence of...

While the principle of tomosynthesis has been known for almost a century, digital breast tomosynthesis (DBT) is a novel technology that owes its rapid development to the introduction of full-field digital mammography (FFDM). This review article covers the principles and design considerations of DBT, including system geometry. Further, the article provides an in-depth introduction to DBT dosimet...

Single crystal catalysts have been used to investigate ethane hydrogenolysis. The apparatus used in these studies allows for catalyst preparation and surface characterization in ultrahigh vacuum (UHV) with an in vacua transfer to a second UHV chamber designed for high pressure kinetic studies. Kinetic measurements on single crystals of nickel show the hydrogenolysis of ethane to be “structure s...

This review investigated the relative performance of digital breast tomosynthesis (DBT) (alone or with full field digital mammography (FFDM) or synthetic digital mammography) compared with FFDM alone for detecting breast cancer lesions in asymptomatic women. A systematic review was carried out according to systematic reviewing principles provided in the Cochrane Handbook for Systematic Reviews ...

Desulfurization of dibenzothiophene (DBT) and alkylated DBT derivatives present in transport fuel through specific cleavage of carbon-sulfur (C-S) bonds by a newly isolated bacterium Chelatococcus sp. is reported for the first time. Gas chromatography-mass spectrometry (GC-MS) analysis of the products of DBT degradation by Chelatococcus sp. showed the transient formation of 2-hydroxybiphenyl (2...

Purpose This paper will explore the lived experiences of staff and service-users regarding the introduction of Dialectical Behaviour Therapy (DBT) into an NHS forensic learning disability (LD) service. Design/methodology/approach Drawing on data from two recent qualitative research studies,the research team used a caseoriented approach to see beyond original findings to capture the shared exper...

Borderline personality disorder (BPD) involves a complex constellation of symptoms including suicidal threats, suicidal gestures, and self-harming behaviors. There are limited effective treatment options for adolescent patients with BDP or BDP traits in the inpatient hospital setting. This paper discusses BPD and BPD traits in adolescents, examines challenges faced by inpatient nurses, summariz...

The topic of Doppler and Bearing Tracking (DBT) problem is to achieve a target trajectory using the Doppler and Bearing measurements. The difficulty of DBT problem comes from the nonlinearity terms exposed in the measurement equations. Several techniques were studied to deal with this topic, such as the unscented Kalman filter. Nevertheless, the performance of the filter depends directly on the...

Objective: The purpose of the present study was to explore facets of the client and therapist-rated therapeutic alliance as predictors of suicide attempts, non-suicidal self-injury, depression, and introject during the course of two psychosocial treatments for borderline personality disorder. Method: A total of 101 women meeting DSM-IV criteria for borderline personality disorder participated i...

Evidence suggests that heightened negative affectivity is a prominent feature of Borderline Personality Disorder (BPD) that often leads to maladaptive behaviors. Nevertheless, there is little research examining treatment effects on the experience and expression of specific negative emotions. Dialectical Behavior Therapy (DBT) is an effective treatment for BPD, hypothesized to reduce negative af...
