Although rejection sensitivity may be an important feature of body dysmorphic disorder (BDD), no studies have examined rejection sensitivity in a clinical sample and compared types of rejection sensitivity in individuals with BDD. Personal and appearance-based rejection sensitivity scores in forty-six patients diagnosed with BDD were compared with published norms. Associations between rejection...

The soil is a heterogeneous and anisotropic medium. Hydraulic conductivity, an intrinsic property of natural alluvial deposits varies both deterministically and randomly in space and has different values in various directions. In the present study, the permeability of natural deposits and its influence on the seepage flow through a natural alluvial deposit is studied. The 2D Finite Difference c...

Stress waves contain useful information about the properties of porous materials; they can be recovered through different non-destructive testing methods such as crosswell, vertical seismic profile, borehole logging as well as sonic tests. In all these methods, it is crucial to assess the effects of frequency on wave attributes including velocity and intrinsic attenuation. The dependency of per...

The routine measurement of direction-dependent reservoir rock properties like permeability often takes place along the axial direction of core samples. As permeability is a tensor property of porous materials, it should be fully described by a tensor matrix or by three main permeabilities in principal directions. Due to compaction, cementation, and other lithification processes, which take plac...

It is reported that the membrane properties can be enhanced by nanomaterials. However, agglomeration will occur due to overdose of nanomaterials subsequently deteriorating performance. The project aims investigate effect concentration cabon nanomaterials: multiwalled carbon nanotubes (MWCNTs) and graphene oxide (GO), on nanocomposite for methyl blue (MB) dye removal. GO/MWCNTs membranes were sy...

Abstract The interlayer spacing (i.e., d -spacing) plays a crucial role in determining the selectivity and permeability of nanofiltration membranes. A high-throughput directional filtration can be achieved by designing controlling -spacing. In this study, -spacing graphene oxide (GO) membrane was tuned fixed to desired value (approximately 0.79 nm) using solution polyethyleneimine (PEI) GO at P...

Due to its reduced invasiveness, low rejection rate, and remarkable ease of administration, transdermal drug delivery (TDD) has recently become a viable alternative oral injectable administration. The medication method is treatment strategy that extraordinarily safe well-tolerated enormous potential for delivering active ingredients against variety illnesses. However, because the skin permeabil...

Abstract Clustering analysis is fundamental for determining dominant discontinuity properties in rock engineering. Orientation has commonly been considered the only factor when performing clustering, which ignores contributions of other to deformations and strengths masses. This study proposes an improved netting algorithm identify sets based on multiple properties. The method takes ten as clus...

the goals of post-transplant management are to manage and treat postoperative complications, and develop a balanced long-term immunotherapy regimen that minimizes infection and side effects but controls rejection. while modern immunosuppressant regimes have reduced rates of graft loss due to rejection, they impart major risks for infection, growth failure, metabolic complications, and malignanc...
