Efficient tracing of system-wide execution, allowing integrated analysis of both kernel space and user space, is something difficult to achieve. The following article will present you a new tracer core, Linux Trace Toolkit Next Generation (LTTng), that has taken over the previous version known as “LTT”. It has the same goals of low system disturbance and architecture independance while being fu...

background: mesenchymal stem cells (msc) have ability to regulate immune response via proinflamatory cytokines. in this study we aimed to investigate the effect of different mechanism for t cell activation and adjacency on immunoregulatory properties of msc. methods: bone marrow mscs were purchased and t cells were obtained from whole blood sample. t cells were activated by two different mechan...

Weldments inevitably shrink during cooling from the melt pool. Residual stresses then occur owing to surrounding constraints. Tensile residual in weldments cause various problems, such as deformation and reduction of fatigue strength. Low-temperature transformation (LTT) welding consumables can reduce tensile stress through volume expansion, which accompanies a phase austenite martensite. In th...

Partially purified antigenic fractions of Leishmania major promastigotes were obtained by sodium dodecyl sulfate (SDS-PAGE) and electro-elution. Three isolated protein fractions designated as frac‌tions (Fr.) 1, 2, and 3 correspond to 40-60, 60-80, 80-100 kilodalton (kDa) respectively. They were used for immunization of BALB/c mice against Leishmaniasis. The effects of these fractions on immune...

Abstract LTT 1445 is a hierarchical triple M-dwarf star system located at distance of 6.86 pc. The primary 1445A (0.257 M ⊙ ) known to host the transiting planet 1445Ab with an orbital period 5.36 days, making it second-closest exoplanet system, and closest one for which dwarf. Using Transiting Exoplanet Survey Satellite data, we present discovery second in 3.12 days. We combine radial-velocity...

Pielke and Chase (1) contend that the troposphere has not warmed since 1979, and that tropospheric warming cannot contribute to observed increases in tropopause height (2). They base this contention on the absence of tropospheric warming in thickness data and geopotential heights obtained from the National Center for Environmental Prediction (NCEP) reanalysis, which is a synthesis of in situ ob...
