3D plume modeling of SPT-100
… of a well known, stationary plasma thruster SPT-100 plume modeling was performed using a hybrid MPI-GPU AMR code CHAOS. Xe atoms, Xe+, and Xe+2 ions are modeled using a kinetic approach. Modeling electrons using a kinetic approach is not feasible in today's computational power for a Hall …

PIC simulation of SPT Hall thrusters : high power operation and wall effects
… refined and used to obtain results for the P5 SPT Hall thruster at 3kw and 5kw operation. Performance data agree well with experiments [3], although very low values of anomalous diffusivity must be used for convergence. Particle temperatures and plasma potentials in the chamber are similar to …

Load and resistance factor design of drilled shafts in shale using SPT and TCP measurements
… tests, such as the Standard Penetration Test (SPT) and the Texas Cone Penetration test (TCP), as surrogates for conventional coring and laboratory testing. In order to utilize results of in-situ tests for design of drilled shafts using Load and Resistance Factor Design (LRFD), it is necessary …

Energy transfer and grain size effects during the Standard Penetration Test (SPT) and Large Penetration Test (LPT)
The Standard Penetration Test (SPT) is the most widely used in-situ soil test in the world. "Large Penetration Test" (LPT) is a term used to describe any scaled up version of the SPT. Several types of LPT have been developed around the world for the purpose of characterizing gravel deposits, as SPT …

Análisis dimensional de la relación entre el ensayo de penetración estándar (SPT) y las velocidades de propagación sísmica primaria y secundaria
… la relación entre el resultado del ensayo SPT en suelos de diversa naturaleza con la velocidad de propagación de ondas sísmicas primarias (vp) y secundarias (vs) obtenidas mediante sísmica de refracción y análisis multicanal de ondas superficiales (MASW), respectivamente. Esto permitirá en …

The role of eicosanoids in the human skin's response to ultraviolet radiation.
… skin of individuals with either skin phototype (SPT) 1 or 4 to UVR. Sixteen normal healthy individuals were selected for study (8 SPT-1 & 8 SPT-4). Buttock skin was investigated by immunohistochemistry for leukocyte subtypes, eicosanoid producing enzymes and NO synthases under basal and …

Entangling symmetry and topology in correlated electrons
… matter named Symmetry-Protected Topological (SPT) phases. These are short-range-entangled quantum phases hosting non-trivial states on their boundaries. In the free-fermion limit, they are famously known as Topological Insulators (TI). Huge progress has been made recently in understanding SPT …

Standard penetration test correlations for Las Vegas soils
Standard penetration tests (SPT) are used to approximate soil properties including the consistency, cohesion and the internal angle of friction. Due to the frequency of cemented sands, gravel and clay in the Las Vegas Valley, the generally accepted SPT correlations vary from actual local …

Assessment of stress and burnout in physical therapist clinical instructors
… component of a student physical therapist’s (SPT’s) journey to becoming a physical therapist (PT). Clinicians who are willing to be clinical instructors (CIs) are needed to educate and mentor the SPT on affective, cognitive, and psychomotor skills, however the role of CI is typically filled …

Applications of conformal field theories in topological phases of matter
… protected and symmetry-enriched topological (SPT/SET) phases in three dimensions are quantum systems that support non-trivial two-dimensional surface states. These surface states develop finite excitation energy gaps when the relevant symmetries are broken. On the other hand, one-dimensional …

Validation and application of the small sample punch test for toughness measurement of steels
… The quasi-non-destructive small punch test (SPT) method was developed to determine the integrity and mechanical properties of materials with use of minimal material removal from components being examined, improving on the conventional mechanical test methods which require a substantial amount …

Examining the Six-Party Talks Process on North Korea: Dynamic Interactions among the Principal States
… on North Korea known as the Six-Party Talks (SPT). Despite the failure in achieving a primary objective of denuclearizing North Korea, the SPT were believed to provide interesting and informative cases to investigate dynamic interactions among states engaged in security talks with different …

The regulation of ceramide content and insulin resistance in skeletal muscle
… We also measured serine palmitoyltransferase (SPT) to determine if AICAR regulates ceramide synthesis by inhibiting SPT. Total SPT protein level increased by -27% (P<0.05) and SPT activity increased by -44% (P<0.05) compared with the control group. By contrast, after muscles were incubated with …
