Dyes wastewater produced during leather processing caused serious environmental pollution. Anionic dyes are always vital crisis in waste treatment. Removal of anionic dyes from tannery wastewater before their discharge into the environment is important for health and environment safety. The use of low-priced and biodegradable adsorbents could be a good method to minimize the environmental impac...

Abstract—Solar water heating is a thermodynamic process of heating water using sunlight with the help of solar water heater. Thus, solar water heater is a device used to harness solar energy. In this paper, a modified solar water heating system (MSWHS) has been proposed over flat plate collector (FPC) and Evacuated tube collector (ETC). The modifications include selection of materials other tha...

With the aid of pH variation, direct transformation of a "1-1" cationic-anionic surfactant pair to a "1-2" cationic-anionic surfactant pair was attained in the system of cetyltrimethylammonium bromide and n-decylphosphoric acid. Owing to the transformation of a "1-1" pair to a "1-2" pair, diverse microstructures and peculiar phase behavior in this cationic-anionic surfactant mixture was obtaine...

Real-time Java is becoming a viable platform for real-time applications, bringing new challenges to a garbage collector. A real-time collector has to be incremental as not to cause deadline misses by suspending an application for too long. In particular, if a real-time collector has to relocate objects in the heap, it must do so incrementally and transparently to the application. This is usuall...

We prepared pH-sensitive anionic liposomes composed solely of anionic bilayer membrane components that were designed to promote efficient release of entrapped agents in response to acidic pH. The pH-sensitive anionic liposomes showed high dispersion stability at neutral pH, but the fluidity of the bilayer membrane was enhanced in an acidic environment. These liposomes were rather simple and wer...

Considerable interest is currently focused on the interactions of beta-2 glycoprotein I (beta2GPI) and anti-phospholipid antibodies with anionic phospholipids in an attempt to understand the association between these antibodies and clinical diseases such as thrombosis. The interactions of beta2GPI and anionic phospholipids have only been characterized partially, and the physiological role of th...

This paper presents BBox, a digital black box to provide for authentic archiving (and, consequently, forensic evidence) for remote auditing in distributed systems. Based upon public key cryptography and trusted computing platforms, the BBox employs standard primitives to ensure the authenticity of records during the transmission from devices to the collector, as well as during their storage on ...

This paper presents the design of a prototypical system to support creative group discussions, like brainstorms. The central concept of this design is the Idea-collector: a tangible input device that is used to organize information displayed on an electronic whiteboard. A working prototype of the Idea-collector was made, following a range of early prototypes. Initial user tests are encouraging ...

We analyze the integration of automatic memory management in a real-time context. We focus on integrating a real-time (copying) garbage collector with hard real-time static-priority periodic tasks. This integration is done by considering the copying collector as an aperiodic task served by a polling server. We analyze the schedulability of this system for any polling server parameters. This ana...

This paper presents BBox, a digital black box to provide for authentic archiving in distributed systems. Based upon public key cryptography and trusted computing platforms, the BBox employs standard primitives to ensure the authenticity of records during the transmission from devices to the collector, as well as during their storage on the collector and retrieval by auditors. Besides presenting...
