Dual Perspectives

Family planning providers' perspectives on dual protection.

CONTEXT Family planning providers can play an important role in helping women to identify their risk of HIV and other sexually transmitted diseases (STDs) and to adopt preventive measures. In-depth investigation of providers' attitudes about approaches to STD risk assessment, contraceptive counseling and dual protection--concurrent protection from STDs and unintended pregnancy--has been limited...

Dual Z-Source Network Dual-Input Dual-Output Inverter

This paper presents a modified nine switch inverter with two inputs and two Z-source networks. This inverter has two DC inputs and two AC outputs. Input DC voltages can be boosted to the required level. Amplitude, frequency and phase of AC output voltages can be controlled, independently. The proposed converter can be used in applications with two unregulated DC sources, which require feeding ...

Membrane Engineering: Future Perspectives

Searching for Key Success Factors of Ubiquitous Supply Chain Management from Dual Perspectives

There has been a little research focusing on the relationship between the key success factors and the benefits of ubiquitous supply chain management (USCM) adoption. Relying on the literature review, case analysis and interview, this research identified the key success factors and the benefits associated to the adoption of USCM. Upon collecting survey data, this research carried out an empirica...

Hybrid Organic/Inorganic Coatings Through Dual-Cure Processes: State of the Art and Perspectives

This paper reviews the current state of the art related to the synthesis and characterization of hybrid organic-inorganic (O/I) coatings obtained through the exploitation of dual-cure processes, which involve a photo-induced polymerization followed by a thermal treatment: this latter allows the occurrence of sol-gel reactions of suitable alkoxy precursors already embedded in the UV-curable syst...
