The biggest challenges faced in big cities are greenhouse gas emission and growing energy needs. Efficient utilization of existing infrastructures has a prominent role in response to the challenges. Energy hub approach embraces performance of different energy networks. Energy hub is defined as a super node in electrical system receiving distinctive energy carriers such as gas and electricity in...

In this paper, a comprehensive model for hub location-routing problem is proposed which no network structure other than connectivity is imposed on backbone (i.e. network between hub nodes) and tributary networks (i.e. networks which connect non-hub nodes to hub nodes). This model is applied in public transportation, telecommunication and banking networks. In this model locating and routing is c...

BACKGROUND Problems associated with pain in several body regions due to work-related musculoskeletal disorders (WRMDs), repetitive movement and negative stress at work are quite common in many manufacturing industries of Latvia, int.al. clothing industry. The aim of this study was to evaluate efficiency of the psychotherapeutic intervention using medical hypnotherapy (MH) program for mind-body ...

This chapter deals with the PNA-assisted rare cleavage (PARC) of duplex DNA. The technique is a variety of the general ‘Achilles’ heel ́ cleavage strategy and uses PNA oligomers to protect very few sites on genomic DNA against enzymatic methylation. As a result, the PARC technique makes it possible to convert common restriction enzymes into a pool of infrequent genome cutters. These artificial g...

Using covering problems (CoP) combined with binary search is a well-known and successful solution approach for solving continuous center problems. In this paper, we show that this is also true for center hub location problems in networks. We introduce and compare various formulations for hub covering problems (HCoP) and analyse the feasibility polyhedron of the most promising one. Computational...

Various different objects have been reported to strangulate the penis. We reported on a patient who used metal radiator clamps for an extended period of time. Workup included history, physical examination and urinalysis. The patient was taken to the operating room for further evaluation with cystourethroscopy and orthopedic wire cutters were used to break the metal bands.

Entrapment of prepuce in a zipper is a common cause of prepuceal injury in children. The reported interventions include dismantling the zipper with bone or wire cutters, to circumcision. A quick, simple and non-traumatic approach to the zipper manipulation is presented in which prepuce is instantly released by lateral compression of the zip fastener, using a pliers.
