The use of laminar airflow rooms and a life island unit for comprised patients was evaluated. Six patients spent a total of 170 days in the laminar airflow rooms and 112 days in the life island unit, and none acquired any exogenous infection. Patients were febrile for 7 out of 170 days (4.1%) in the laminar airflow rooms and 4 out of 112 days (3.6%) in the life island unit. No significant diffe...

Past studies of bird migration times have shown great variation in migratory responses to climate change. We used 33 years of bird capture data (1970–2002) from Manomet, Massachusetts to examine variation in spring migration times for 32 species of North American passerines. We found that changes in first arrival dates – the unit of observation used in most studies of bird migration times – oft...

Information integrating in Semantic Concept Networks (SCN) is one of the important operations in these networks. These operations require resource usage. Due to the limited resource of units, the resource productivity should be considered as a key objective in design of Semantic Concept Networks. Therefore the Integrating is a suitable method that used in resource usage management. For this pur...

Many studies have examined the role of mean climate change in agriculture, but an understanding of the influence of inter-annual climate variations on crop yields in different regions remains elusive. We use detailed crop statistics time series for ~13,500 political units to examine how recent climate variability led to variations in maize, rice, wheat and soybean crop yields worldwide. While s...

Tibetan Plateau is one of the largest and most unique habitats for organisms including arbuscular mycorrhizal fungi (AMF). However, it remains unclear how AMF communities respond to key environmental changes in this harsh environment. To test if precipitation could be a driving force in shaping AMF community structures at regional scale, we examined AMF communities associated with dominant plan...

Introduction: Quality and knowledge-based human resources are the most important competitive advantage and the scarcest source in today's knowledge-based economy. Hence, the development of the capabilities, expertise, and commitment of well-trained employees is considered the most important management challenge in our time. The present study was conducted to investigate the role of Management S...

Mortality decline has historically been a result of reductions in the level of mortality at all ages. The slope of mortality increase with age has been remarkably stable. A number of leading researchers on aging, however, suggest that the next revolution of longevity increase will be the result of slowing down the rate of aging. In this paper, we show mathematically how varying the pace of sene...

women have to leave India before they have arrived at the age "when menstruation ceases. When, however, the occasion does come, the responsibility is doubly felt, and the want of personal experience makes the desire for guidance all the more strong. The information to be gleaned from sources usually available is fragmentary and deficient in detail, and all are ready to welcome any author who co...
