introduction: many organizations, especially service oriented ones, relative to their goals and mission, have a special view towards quality phenomena and its management. methods: this paper analyzes medical service quality in one case the internal section of shaheed rahnemoon hospital based on the basis of gap analysis model and servqual technique. a questionnaire was designed and applied to m...

Pollinators are a key component of global biodiversity, providing vital ecosystem services to crops and wild plants. There is clear evidence of recent declines in both wild and domesticated pollinators, and parallel declines in the plants that rely upon them. Here we describe the nature and extent of reported declines, and review the potential drivers of pollinator loss, including habitat loss ...

Michael Hogan, chair of the President's New Freedom Commission on Mental Health, describes the commission's findings on the fragmentation of the public mental health services infrastructure and its effort to formulate strategies for improving the alignment of federal, state, and local policy and practice. Clinical treatment needs to be coordinated with supportive services such as housing, educa...

background: heat shock protein a2 (hspa2) is correlated with sperm maturity and function. therefore, dysfunctional expression of this gene results in abnormal spermatogenesis. on the other hand, dna damage in spermatozoa is considered to be an important cause of male infertility, and the presence of sperm with dna fragmentation and chromatin abnormalities in human ejaculates is well documented,...

This paper presents the design of a secure and fault-tolerant CORBA datastore based on the Fragmentation-Redundancy-Scattering (FRS) technique. This technique consists in fragmenting the con dential data and scattering the resulting fragments across several archives. The FRS-Datastore service interacts with the other CORBA services, in particular with the Persistence, Security and Trading servi...

Service oriented middleware draws a lot of attention in current research on sensor networks. The automatic distribution of services within a network and the preservation of this distribution is a fundamental aspect of network applications with self-x properties. The network gains the ability to react on mobility, network fragmentation, node failures and new user demands. This paper proposes a d...

The increasing proliferation of mobile devices has resulted in people being able to express their opinions and sentiments more easily. To obtain people’s preferences and evaluations about products and services, sentiments expressed over Websites and social network services need to be analyzed. However, due to the diversity of the media and the short lengths of messages, the sentiment data is fr...

Background: It is stated that pentoxifyline can improve sperm motility and suggested to use in ART for asthenozoospermia. But, probable effect of this drug on sperm DNA in unknown. Our main goal was to evaluate the impact of pentoxifyline on sperm DNA fragmentation. Materials and Methods: Thirty eight asthenozoospermic patients were selected for this prospective study. After direct swim-up, spe...

Few studies directly address the consequences of habitat fragmentation for communities of pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes). Bees typically live in habitats where nesting substrates and bloom are patchily distributed and spatially dissociated. Bee studies have all defined habitat fragments as remnant patches of floral hosts or forests,...

1. Forests provide critical habitat for many species, essential ecosystem services, and are coupled to atmospheric dynamics through exchanges of energy, water and gases. One of the most important changes produced in the biosphere is the replacement of forest areas with human dominated landscapes. This usually leads to fragmentation, altering the sizes of patches, the structure and function of t...
