Keystroke biometrics authentication system is based on a password and keystroke biometric features captured when a user is typing in the password. The system offers a higher level of security and convenience for computers. The system does not require additional hardware as it can be used with any existing keyboard, making it relatively inexpensive and fairly unobtrusive to the user. There have ...

direct contact membrane distillation (dcmd) which emerges as an alternative separation technology can effectively perform a colloidal separation process under thermal driven force. dcmd is capable of extracting pure water from aqueous solutions containing non-volatile nanoparticles through the hydrophobic microporous membrane when a vapour pressure difference was established across the membrane...

the effect of membrane molecular weight cut off (mwco) at three levels (10, 20 & 50 kd) on dynamic behavior of permeate flux (jp), hydraulic resistances (total hydraulic resistance, rt; reversible fouling resistance, rrf; irreversible fouling resistance, rif and membrane hydraulic resistance, rm) and milk solutes rejection (protein, rp; fat, rf; lactose, rl; minerals, rm and total solids, r...

Background: Correlations between bone marrow, heart, kidney, liver, skin and lung transplant rejection or survival with human cytokine gene polymorphisms have been described. There are also reports about the role of cytokines and Tumor Necrosis Factors-Alpha (TNF-α) on corneal transplant in animal models. Further studies are needed to clarify the role of cytokines in corneal allograft rejection...

The paper presents modeling the hydro-turbine governing system with delay in application to turbo-machinery control. originates from wave phenomenon encountered pressure water conduit connected turbine. To facilitate PID control tuning turbine and model is linearized it results linear time referred as neutral system. Particularly, disturbance rejection achieved by response varying power loads. ...

background: the innate immunity plays an important role in the host response to transplantation by toll-like receptors and results in development of acute allograft rejection. the aim of this study was to evaluate the association of tlr2 and cd14 (co-receptor) gene polymorphisms with acute rejection in kidney transplant recipients.   methods : the study was conducted in a population of 239 subj...

background: human cornea expresses functional fas-ligand capable of killing fas+ activated lymphocytes. fas expression is partly regulated by -670 a/g polymorphism in the promoter region of fas gene. objective: the aim of the present study is to determine the association between fas-670a/g polymorphism and survival of corneal transplantation. methods: in 276 graft recipients who mainly underwen...

Seismic reservoir characterization aims to transform obtained seismic signatures into reservoir properties such as lithofacies and pore fluids. We propose a Markov chain Monte Carlo (McMC) workflow consistent with geology, well‐logs, seismic data and rock‐physics information. The workflow uses a multiple‐point geostatistical method for generating realizations from the prior distribution...

for monitoring of renal transplant function, serum b2m was evaluated in 23 recipients. according to clinical diagnosis the patients were in four groups: 1) successful renal transplant the mean concentration of sb2m pretransplantation was 73.1±26.1 mg/l but decreased to nearly normal level (4.43±1.17 mg/l) within 24-48h and then reached to 3.1 mg/l duting 20 days after transplantation. 2) renal ...
