leishmania antigens are weak immunogens and need to be potentiated by various adjuvants and delivery systems. alginate microspheres as an antigen delivery system and quillaja saponins (qs) as an immunoadjuvant have been used to enhance the immune response against autoclaved leishmania major (alm). microspheres were prepared by an emulsification technique and characterized for size, encapsulatio...

 Background: Among all cancers, malignancies of gastrointestinal tract are the most common cancer among Iranian population. Dietary behavior is thought to be the most important risk factor in gastric cancer. Fear and perceived severity are two important constructs of the protection motivation theory (PMT). Despite the evidence of the impact of these two constructs in modifying dietary habi...

Capacitor-couple technique used to lower snapbacktrigger voltage and to ensure uniform ESD current distribution in deep-submicron CMOS on-chip ESD protection circuit is proposed. The coupling capacitor is realized by a poly layer right under the wire-bonding metal pad without increasing extra layout area to the pad. A timing-original design model has been derived to calculate the capacitor-coup...

A substrate-triggered technique is proposed to improve ESD protection efficiency of the stacked-NMOS device in the mixed-voltage I/O circuit. The substrate-triggered technique can further lower the trigger voltage of the stacked-NMOS device to ensure effective ESD protection for the mixed-voltage I/O circuit. The proposed ESD protection circuit with the substrate-triggered technique for 2.5V/3....

In this paper, we assess the protection mechanisms entered into recent clients to fight against the Sybil attack in KAD, a widely deployed Distributed Hash Table. We study three main mechanisms: a protection against flooding through packet tracking, an IP address limitation and a verification of identities. We evaluate their efficiency by designing and adapting an attack for several KAD clients...

We constructed and characterized a Xanthomonas campestris pv. phaseoli oxyR mutant. The mutant was hypersensitive to H2O2 and menadione killing and had reduced aerobic plating efficiency. The oxidants' induction of the catalase and ahpC genes was also abolished in the mutant. Analysis of the adaptive responses showed that hydrogen peroxide-induced protection against hydrogen peroxide was lost, ...

The most important causes of bridge failure are local scour. In this study, laboratory experiments were conducted to investigate the effectiveness of slot as a protection device in reduction of depth of scour at cylindrical piers under clear water flow conditions. The development time of scour depth at the circular pier with and without a slot as a protection device was conducted. The experimen...

This article describes the implementation of early warning feature in an over-current protection module designed for limiting the surgecurrent in communication applications. The early warning signal is generated by a surge-current sensor and a temperature sensor mounted on the protection module. Described solution decreases fault latency and consequently improves the efficiency of the on-line f...
