This paper discusses the vulnerability and adaptation of the agricultural sector of China to global wanning. Based on a summarization of Chinese agricultural and general circulation model trends, adverse impacts on China's agriculture caused by a warming and drying climate were identified. Because of limited irrigation potential, the sustainable development of Chinese agriculture will be diffic...

Cooling towers (CTs) are a leading source of outbreaks of Legionnaires' disease (LD), a severe form of pneumonia caused by inhalation of aerosols containing Legionella bacteria. Accordingly, proper maintenance of CTs is vital for the prevention of LD. The aim of this study was to determine the distribution of Legionella in a subset of regionally diverse US CTs and characterize the associated mi...

Insufficient chilling resulting from rising winter temperatures associated with climate warming has been an area of particular interest in boreal and temperate regions where a period of cool temperatures in fall and winter is required to break plant dormancy. In this study, we examined the budburst and growth of trembling aspen (Populus tremuloides Michx.), balsam poplar (Populus balsamifera L....

For many species and seed sources used in restoration activities, specific seed germination requirements are often unknown. Because seed dormancy and germination traits can be constrained by phylogenetic history, related species are often assumed to have similar traits. However, significant variation in these traits is also present within species as a result of adaptation to local climatic cond...

Preschool can have positive effects on the development of a healthy lifestyle. The present study analysed to what extent different conditions, structures and behavioural models in preschool and family-children's central social microsystems-can lead to differences in children's health resources. Using a cross-sectional mixed methods approach, contrast analyses of "preschools with systematic phys...

BACKGROUND The purpose of this study was to integrate relevant goal-setting theory and to identify if trainees' goal orientations have an impact on the assigned goals-performance relationship. METHODS Trainees attended 1 of the 3 goal-training activities (do your best, performance, or learning goals) for knot tying (KT) and camera navigation (CN) during the 3rd-year clerkship rotation. Questi...

Several observational and objective methods are available to assess sedation depth; however, data regarding their accuracy in differentiating deep sedation are limited. In this study we compared 3 sedation tools in children from birth to 18 yr of age and determined their relative value in detecting deep levels of sedation. Bispectral index monitoring (BIS), Modified Maintenance of Wakefulness T...

The purpose of this study was to examine the validity and reliability of a new stair sprinting power (SSP) test and, in addition, develop norms for college-age students. Two hundred twenty-seven college-age volunteers participated in the study (ages: males, [Latin capital letter X with macron above] = 21.6 +/- 2.264 years; females, [Latin capital letter X with macron above] = 22.3 +/- 4.214 yea...

The object of this study is to present our experience in dealing with coarctation of the aorta and to discuss policy in the management of individual patients who have widely varying ages and symptoms, sometimes complicated by additional lesions. Surgical treatment, which is on a national basis, was developed rather hesitantly at first, but is now practised with confidence. Forty-four cases have...
